A. SELECTED FINANCIAL DATA

Our consolidated financial statements included in this annual report are prepared in accordance with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board, or IASB.

We publish our consolidated financial statements in Mexican pesos. References in this annual report to “dollars,” “U.S.$” or “U.S. dollars” are to United States dollars. References to “Ps.” or “pesos” are to Mexican pesos. This annual report contains translations of certain Mexican peso amounts into U.S. dollars at specified rates solely for your convenience. These translations should not be construed as representations that the Mexican peso amounts actually represent such U.S. dollar amounts or could be converted into U.S. dollars at the rate indicated. Unless otherwise indicated, U.S. dollar amounts have been translated from Mexican pesos at an exchange rate of Ps. 17.34 to U.S.$ 1.00, the exchange rate determined by reference to the free market exchange rate as reported by Banco de Mexico, or Banxico, as of December 31, 2015.

The term “billion” as used in this annual report means 1,000 million. Certain amounts in this annual report may not sum due to rounding.

Financial Data

The following table presents our selected consolidated financial information for or as of each of the periods or dates indicated, and has been derived in part from our audited consolidated financial statements. This information should be read in conjunction with, and is qualified in its entirety by reference to, our consolidated financial statements, including the notes to our consolidated financial statements.

The consolidated financial statements of income and other comprehensive income for the years ended December 31, 2014, 2013, 2012 and 2011 have been adjusted to reflect the reclassification of the SPC Projects, which previously had been classified as discontinued operations, as a continuing operation reported in our Concessions segment.

(1) Except share, per share, and per ADS data. Amounts stated in U.S. dollars as of and for the year ended December 31, 2015 have been translated at a rate of Ps. 17.34 to U.S.$ 1.00 using the Banxico free market exchange rate on December 31, 2015.

(2) Represents the adjustment to fair value for an acquisition by our subsidiary State Town Corp, S.A. of a property in Panama. See “Item 5. Operating and Financial Review and Prospects—Operating Results” and Note 10 to our consolidated financial statements.

(3) Gross profit is calculated as the sum of construction revenues, concession revenues and sales of assets and other, less their respective costs, and does not include fair value upon recognition of real estate inventories.

(4) For 2015, includes principally (i) Ps. 507 million in restructuring costs related to severance payments, (ii) Ps. 128 million from the deconsolidation of San Martin Contratistas Generales, S.A. or San Martin, which we ceased consolidating in October 2015 due to our loss of control over the entity, as a result of our decrease in shareholding from 51% to 31.2%, (iii) Ps. 112 million from the sale of Punta Condesa Group, (iv) Ps. 163 million of a gain resulting from an adjustment in the contingent consideration for the acquisition of Facchina, (v) Ps. 209 million gain from the sale of equity method investments; and (vi) profit related to the sale of property, plant and equipment for Ps. 228 million. For 2014, includes principally (i) Ps. 194 million for the additional payments made as part of the acquisition cost of San Martín Contratistas Generales, S.A., or San Martin, (ii) Ps. 17 million in loss on sales of shares mainly related to the Aguas Tratadas del Valle de Mexico consortium, or ATVM, and (iii) Ps. 10 million in gain on sales of property, plant and equipment.

Diluted earnings (loss) per share and per ADS are calculated by giving effect to all potentially dilutive common shares outstanding during the period. The dilutive effect of our potential ordinary shares does not have a material effect on our determination of earnings per share; thus, diluted earnings per share approximates basic earnings per share for the years ended December 31, 2015, 2014, 2013, 2012, and 2011.

In recent decades, the Mexican Central Bank has consistently made foreign currency available to Mexican private-sector entities (such as us) to meet their foreign currency obligations. Nevertheless, in the event of shortages of foreign currency, we cannot assure you that foreign currency would continue to be available to private-sector companies or that foreign currency needed by us to service foreign currency obligations or to import goods could be purchased in the open market without substantial additional cost.

Fluctuations in the exchange rate between the peso and the U.S. dollar will affect the U.S. dollar value of securities traded on the Mexican Stock Exchange (Bolsa Mexicana de Valores), and, as a result, will likely affect the market price of our American Depository Shares, or ADSs. Such fluctuations will also affect the U.S. dollar conversion by The Bank of New York, the depositary for our ADSs, of any cash dividends paid by us in pesos.

On May 13, 2016, the exchange rate was Ps. 18.21 per U.S.$1.00, according to the U.S. Federal Reserve Board. The above rates may differ from the actual rates used in the preparation of the financial statements and the other financial information appearing in this Form 20-F.

For a discussion of the effects of fluctuations in the exchange rates between the Mexican peso and the U.S. dollar, see “Item 10. Additional Information—Exchange Controls.”

B. RISK FACTORS

Risks Related to Our Operations

We have insufficient liquidity to pay or repay our debt and other obligations. If a restructuring of our debt is not successful, we may not be able to pay all or a portion of the principal or interest on our unsecured debt and our operations may be adversely affected.

In recent years, we have incurred substantial indebtedness to finance our Company’s growth and operations. As of December 31 2015, we had consolidated indebtedness to banks, financial institutions and other lenders of approximately Ps. 69,913 million. Currently, income from our projects does not generate sufficient liquidity to satisfy our outstanding debt and other payment obligations.

4

As of December 2015, we have been in default on payments under our unsecured indebtedness, including our Senior Notes. See “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Indebtedness.” In December 2015, we announced that we would pursue a restructuring of our debt. We can make no assurances that a restructuring will be successful or that our projects in the future will satisfy our payment obligations.

On October 29, 2015, we announced our engagement of Rothschild Mexico as a financial advisor to advise us in evaluating debt restructuring alternatives to implement a long-term solution to our capital structure and debt service requirements.

In December 2015, we announced our engagement of FTI Consulting as a financial advisor to advise us in preparing a cost-cutting plan and restructuring plan, in conjunction with Rothschild Mexico.

During this time, Standard & Poor’s Investment Advisory Services, (“Standard & Poor’s”) has lowered our foreign and local currency corporate credit ratings to “D”, as well as the ratings on our senior unsecured notes due 2017, 2021, and 2024 with a negative outlook; additionally, Moody’s Investors Service (“Moody’s”) lowered our long-term corporate credit rating and the ratings on our existing notes to Caa3 with negative outlook. These negative credit ratings and downgrades have further restricted our sources for short-term financing, thereby impeding our ability to finance our operations. Furthermore, the negative publicity surrounding these recent downgrades has further adversely affected our ability to pay our providers.

If our current liquidity crisis continues, our ability to undertake important activities may be impaired, including:

• our ability to adjust to rapidly changing market conditions, thus making us more vulnerable in the event the downturn in general economic conditions or our business continues;

• our ability to maintain relationships with key suppliers;

• our ability to participate in public bids;

• our ability to enter into long-term contracts with customers;

• our ability to undertake capital expenditures;

• our ability to maintain a positive image to regulators, investors, lenders or credit rating agencies; or

• our ability to maintain and improve our enterprise value.

We are in default under our indentures and other financial instruments, and our future is dependent upon our ability to restructure our debt and other financial instruments.

In order to preserve the cash necessary to continue our operations, we did not make a U.S.$31 million scheduled interest payment due November 30, 2015 on our U.S.$ 700 million in 8.875% senior notes due 2024, or (the “2024 Notes”). In 2016, we did not make a U.S.$6 million scheduled interest payment due January 25, 2016 on our U.S.$ 150 million of 8.375% senior notes due 2017, (the “2017 Notes”), and we did not make a U.S.$ 22 million scheduled interest payment due February 4, 2016 on our U.S.$ 500 million of 8.9% senior notes due 2021, (the “2021 Notes” and together with the 2017 Notes and the 2024 Notes the “Senior Notes”). Under the indentures governing the Senior Notes, the noteholders have the right to accelerate this debt, resulting in cross-defaults under certain other corporate debt of our Company starting in December 2015. As a result, certain creditors have foreclosed on the collateral securing our corporate debt or initiated other remedial actions against us.

Any restructuring is dependent upon third parties over whom we have no control. We cannot assure that these third parties will be willing to engage in negotiations with us, nor that any negotiations will completely restructure or reduce our debt obligations. Even if a restructuring is successful with third parties, we cannot assure that any agreements reached will not be overturned in Mexican courts.

5

Our insufficient liquidity could severely impact our ability to continue as a going concern.

Our Company’s operations require liquidity. If we are unable to obtain and maintain sources of liquidity, we will not be able to complete our construction projects and, consequently, will not generate income under those projects or be able to pay our employees.

Our ability to continue as a going concern could also be affected by our overall inability to pay our debt and other payment obligations, such as taxes and secured credit arrangements.

Our consolidated financial statements have been prepared under the assumption that we will continue as a going concern. However, our independent auditors have stated in their most recent report that there is substantial doubt about our ability to continue as a going concern. Our consolidated financial statements do not include any adjustments that might result from the outcome of that uncertainty. If we are not successful in consummating a debt restructuring and in generating sufficient cash from operating activities to meet our financial obligations and to make essential capital expenditures, our inability to successfully restructure our debt would materially and adversely affect our financial condition and continuing operations and would likely cause us to seek bankruptcy court protection. If we are required to liquidate our operations, the holders of our debt and our shareholders will likely incur a significant loss.

If the debt restructuring negotiations with our creditors are not successful, we face a substantial risk of Mexican reorganization-related proceedings.

If we remain in default on our obligations, including our Senior Notes, some or all of our creditors will have the option of taking legal action against us, including starting an involuntary reorganization proceeding in Mexico. Further, we may choose to start a voluntary reorganization proceeding under either the Ley de Concursos Mercantiles (Mexican Bankruptcy Law) or the United States Bankruptcy Code. We cannot predict the duration of any such restructuring. A reorganization proceeding would likely result in significant changes to our existing obligations that could include the cancellation or rescheduling of all or part of those obligations. While any such proceeding is pending, our ability to operate or manage our business, to retain employees, to maintain existing or create new customer relationships, to continue to collect payments for our services or to obtain any type of funding or financing would likely be materially adversely affected.

We are dependent on third parties agreeing to renegotiate our debt and our ability to make agreements with them using the assets we currently have. If we are unable to do so, our liquidity will be insufficient and we will be forced to initiate reorganization proceedings in court.

Our current Mexican construction projects may be terminated by our clients if one of our construction subsidiaries is directly subject to a bankruptcy proceeding under the Ley de Concursos Mercantiles.

If we were declared bankrupt, our creditors would find it difficult to collect payment on our unsecured debt instruments.

If we were declared bankrupt by a Mexican court, or if we were subject to a reorganization proceeding in a Mexican court, our obligations under our debt securities would be dependent upon the outcome of the bankruptcy or reorganization proceeding. Payment, if any, of our unsecured debt obligations would occur at the same time as the claims of all of our unsecured creditors are satisfied, if and to the extent funds are sufficient. A substantial portion of our assets are pledged as collateral under guarantee agreements and the value of those assets may be insufficient to generate funds to repay our secured creditors. A Mexican court may order unsecured creditors to accept a significant reduction in repayment. There can be no assurance that our unsecured creditors would receive any meaningful recovery from a bankruptcy or reorganization proceeding.

We may be unable to realize the value of our planned divestitures in time to repay our creditors or reach agreements with them and we may not receive the full expected value from them. Our restructuring program requires liquidity during the time that we are negotiating with our creditors.

We are currently prioritizing the continuation of ongoing projects. As a result, liquidity generated from our projects is applied primarily to satisfy financial and operating expenses directly related to those projects. Consequently, liquidity to carry out our restructuring program is dependent upon income from divestitures. These divestitures may not occur as planned or may be subject to pricing pressure. Either of these situations would adversely affect our creditors in either our ability to repay debt or our ability to renegotiate our debt. As of December 31, 2015, we have not classified any asset as held for sale.

We and our independent registered accounting firm have concluded that our internal control over financial reporting was not effective as of December 31, 2015. Investor confidence and the market price of our common shares may be adversely impacted if we are unable to maintain effective internal control over financial reporting.

As we are subject to reporting obligations under the U.S. federal securities laws, we are required by the U.S. Securities and Exchange Commission, or SEC, pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley Act, to include a report on our internal control over financial reporting in our annual reports on Form 20-F to disclose our management’s assessment of the effectiveness of our internal control over financial reporting.

In addition, our annual reports on Form 20-F shall include an independent registered public accounting firm’s attestation report on the effectiveness of our internal control over financial reporting.

In connection with the evaluation of our internal control over financial reporting as of December 31, 2015, our management identified material weaknesses in our internal control over: (i) a deficiency in our Company’s control activities, information and communication, and monitoring activities associated with the valuation of deferred tax assets related to net loss carry forwards, and (ii) deficiencies in our Company’s control activities, information and communication, and monitoring activities in our Civil Construction Segment.

These material weaknesses arose during the restructuring process of our Company and we are defining a remediation plan to be implemented promptly. To address these material weaknesses we have identified, we have added the task of preparing a risk analysis and action plan for these material weaknesses to the Audit Committee’s agenda.

The actions that we are taking are subject to ongoing management review. See “Item 15 —Controls and Procedures.” However, we cannot assure you that these remedial measures will be effective or complete, or that we will be able to implement such measures or any additional measures in a timely manner. After we implement these remedial measures, these material weaknesses identified in our internal control over financial reporting may not be successfully remedied.

The covenants in our debt agreements could cause a reduction in our income from operations.

Some of our debt instruments have cross default provisions and restrictive covenants, including mandatory repayment obligations that require prepayment in the event of an asset sale or failure to maintain certain debt coverage ratios. If a mandatory payment is triggered, or any other covenant is breached in project-related debt, proceeds from our project-related debt may not be available to use in the operation of those projects. In 2015, certain creditors foreclosed on collateral securing our secured debt obligations, such as Deutsche Bank, which foreclosed on certain of our shares in GACN. We entered into remedial agreements with other lenders related to assets securing debt obligations such as shares in San Martin thereby decreasing our ability to generate income from this and other assets or investments.

We may not be able to make payments in U.S. Dollars. We have to pay interest and principal on our dollar-denominated debt with revenues generated in pesos or other currencies, as we do not generate sufficient revenue in U.S. Dollars from our operations.

The depreciation of the Mexican peso has negatively affected our ability to repay any debt we have in U.S. dollars. The peso depreciated from Ps. 14.7348 per U.S. dollar on December 31, 2014 to Ps. 17.3398 per dollar on December 31, 2015, and was 18.21 on May 13, 2016. Given that more than 69% of our income is paid in Mexican pesos, this depreciation trend and any further depreciation will additionally negatively affect our ability to make payments in U.S. dollars. Only our Facchina subsidiary generates a significant portion of its income in U.S. dollars, and our bonding and operating agreements significantly restrict our ability to use the cash from operations for any purpose other than that company’s operations.

Our business and our ability to continue operations are highly dependent on sales volume, which has been significantly reduced as a result of our financial situation.

We are highly dependent on the Mexican government for sales. Since announcing our restructuring we have not yet been awarded a significant contract by the Mexican government. Although the rate of awards is lower than in prior years across the industry, not receiving any project awards is not viable going forward. If we are not able to come to agreements with clients for additional works, or to qualify to bid on new projects, we will be unable to operate.

If we are subject to bankruptcy proceedings, it may result in the inability of holders of our shares and ADSs to recover any of their investments.

Our future is dependent on our ability to refinance or restructure our indebtedness successfully. If we fail to do so for any reason, we might not be able to continue as a going concern and could be forced to seek relief under applicable bankruptcy procedures, in which case our shares and ADSs may lose all or substantial amount of their value.

Our performance is tied to Mexican public sector spending on infrastructure facilities.

Our performance historically has been tied to Mexican public sector spending on infrastructure facilities and to our ability to bid successfully for such contracts. Mexican public sector spending, in turn, generally has been dependent on the state of the Mexican economy. A decrease in public sector spending as a result of a deterioration of the Mexican economy, changes in Mexican governmental policy, or for other reasons can have an adverse effect on our financial condition and results of operations. Beginning in the second half of 2008 and due to the impact of the credit crisis and turmoil in the global financial system, the rate of awards of infrastructure projects in Mexico was slower than contemplated under the National Infrastructure Program, although we did see an increase in contracting in 2010 and 2011 for our company. Federal elections were held in Mexico on July 2, 2012, Enrique Peña Nieto of the political party known as the Partido Revolucionario Institucional, or PRI, obtained a plurality of the vote and assumed office on December 1, 2012. In 2015, the PRI again won a plurality with its coalition parties in Congressional elections. Although the PRI won a plurality of the seats in the Mexican Congress, no party succeeded in securing a majority in either chamber of the Mexican Congress. The absence of a clear majority by a single party is likely to continue, at least until the Presidential and Congressional elections in 2018. In the period leading up to

8

and following the change in presidential administration, the number of large public sector construction contracts the Mexican government offered for public bidding decreased. The rate of awards decreased in 2014 due to a decrease in public works spending in Mexico. In 2015 the rate of awards decreased due to both a decrease in public works spending in Mexico as well as the reputational and other consequences of our restructuring. We cannot provide any assurances that the rate of awards will not increase or decrease. Decreases in the number of available projects or delays in bidding for projects, including delays in payment for current projects, can also result from the federal, state or local administration reviewing the terms of project contracts granted by the previous administration or authorities pursuing different priorities than the previous administration or authority. Additionally, the Mexican government may face budget deficits that prohibit it from funding proposed and existing projects or that cause it to exercise its right to terminate our contracts with little or no prior notice. The decrease in the price of oil in 2015 negatively affected Mexico’s economy generally and its infrastructure spending in particular. Traditionally Mexico’s revenues have been highly dependent on oil revenues. With the drop in price and its effect on the Mexican Peso, Petroleos Mexicanos decreased its spending by 11.5% in February 2015, further producing decreases in infrastructure spending. We cannot provide any assurances that economic and political developments in Mexico, over which we have no control, will not have an adverse effect on our business, financial condition or results of operation. See “—Risks Related to Mexico and Other Markets in Which We Operate—Economic and political developments in Mexico could affect Mexican economic policy and adversely affect us.”

Our current accounts payable to our key providers and other providers may impair our ability to successfully complete our current projects or to bid at competitive prices for future projects.

Our accounts payable to our providers was Ps. 7,285 million at December 31, 2015. There are key products in the Mexican market that we generally need to source for all our projects, including cement and machinery. If our key providers or other local providers stop providing services for our current projects it may severely delay or impair our projects. If our failure to pay key providers results in their ceasing to provide goods and services, we would be forced to obtain these products from providers who may require guarantees or uncompetitive prices.

Competition from foreign and domestic construction companies may adversely affect our results of operations.

The market for construction services in Mexico is highly competitive. As a result of the integration of the Mexican economy into the global economy, we compete with foreign construction companies for most of the industrial and infrastructure projects on which we bid in Mexico and civil construction projects as well. We believe that competition from foreign companies has reduced and may continue to reduce the Mexican construction industry’s operating margins, including our own, as foreign competition has driven down pricing. Furthermore, our foreign competitors may have better access to capital and greater financial and other resources, which would give them a competitive advantage in bidding for such projects.

Foreign competition also allows sponsors such as government agencies for infrastructure construction and industrial construction projects to require contractors to provide construction on a “turnkey” basis, which increases our financial risks.

Our use of the percentage-of-completion method of accounting for construction contracts could result in a reduction of previously recorded profits.

Under our accounting policies, we measure and recognize a large portion of our revenues and profits under the percentage-of-completion accounting methodology for construction contracts. This methodology allows us to recognize revenues and profits ratably over the life of a construction contract, without regard to the likelihood, and timing, of receipt of cash payments, by comparing the amount of the costs incurred to date against the total amount of costs expected to be incurred. The effect of revisions to estimated costs, and thus revenues, is recorded when the amounts are known and can be reasonably estimated. These revisions can occur at any time and could be material, including under contracts like our construction contract for Line 12 of the Mexico City metro system. However, as our clients are under scrutiny related to their processes of project variation and controls, we reevaluated those projects where the recovery of amounts included in our progress toward completion was unlikely either in the near-term or at all and determined that we needed to reserve a significant portion of amounts owed to us related to costs and estimated earnings in excess of billings, thereby affecting our profits. Given the uncertainties associated with these types of contracts and inherent in the nature of our industry, it is possible for actual costs to vary from estimates previously made, which may result in reductions or reversals of previously recorded profits in the future as well.

Our future revenues will depend on our ability to finance and bid for infrastructure projects.

In recent years we have been increasingly required to contribute equity to and arrange financing for construction projects. We are currently undertaking various construction and infrastructure projects that involve significant funding commitments and minimum equity requirements. Our policy is not to bid for projects that have significant financing requirements without prior funding commitments from financial institutions. However, we cannot assure you that we will obtain financing on a timely basis or on favorable terms, particularly due to the continuing defaults on our indebtedness and the ongoing restructuring process. The financing requirements for public construction contracts may range from a term of months to the total construction period of the project, which may last several years. Providing financing for construction projects, however, increases our capital requirements and exposes us to the risk of loss of our investment in the project. In particular, uncertainty and tightening in the global credit markets, including developments related to the global economic crisis, may adversely affect our ability to obtain financing. Our inability to obtain financing for any of these projects could have a material adverse effect on our financial condition and results of operation. Additionally, EMICA (our parent company) had been increasingly been required to give parent guarantees as a form of credit enhancement for debt of our subsidiaries, as well as to accept take-out financing clauses (where the debtor commits to either incur or cause the project company to incur permanent or long-term indebtedness in order to refinance short-term project indebtedness) and clauses which, if invoked, typically require EMICA to pay additional amounts under a loan agreement as may be necessary to compensate a lender for any increase in costs to such lender as a result of a change in law, regulation or directive. Our ability to obtain financing through parent company guarantees may also be affected by our parent company’s defaults.

Global credit crises or unfavorable general economic and market conditions, including those that affect the Mexican economy may negatively affect our liquidity, business and results of operations, and may affect a portion of our client base, subcontractors and suppliers.

The effect of an economic crisis and related turmoil in the global financial system on the economies in which we operate, our clients, our subcontractors, our suppliers and us cannot be predicted. It could lead to reduced demand and lower prices for construction projects, air travel and our related businesses. The Mexican economy has suffered from a devaluation of the Peso versus the U.S. dollar during 2015, as well as a significant decrease in the price of oil, both of which have affected the Mexican financial markets. See “—Our performance is tied to Mexican public sector spending on infrastructure facilities.” In response to market conditions, clients may choose to make fewer capital expenditures, to otherwise slow their spending on or cancel our services, to delay payments (which may in turn cause us to pay our providers more slowly) or to seek contract terms more favorable to them. Furthermore, any financial difficulties suffered by our subcontractors or suppliers could increase our costs or adversely impact project schedules.

Many lenders and institutional investors have reduced and, in some cases, ceased to provide funding to borrowers. Credit rating agencies have also become more stringent in their debt rating requirements. Continued disruption of the credit markets could adversely affect our suppliers’, clients’ (particularly our private sector clients’) and our own borrowing capacities, which could, in turn, adversely affect the continuation and expansion of our projects because of contract cancellations or suspensions, project delays (as delays in our supply chain can in turn affect our deliverables) or payment delays or defaults by our clients, which could result in the need to foreclose on our rights to collateral. See “—We may have difficulty obtaining the letters of credit and performance bonds that we require in the normal course of our operations.” Our ability to expand our business would be limited if, in the future, we were unable to access or increase our existing credit facilities on favorable terms or at all. These disruptions could negatively affect our liquidity, business and results of operations.

Under our construction contracts, we are increasingly required to assume the risk of inflation, increases in the cost of raw materials and errors in contract specifications, which could jeopardize our profits and liquidity.

Historically, a majority of our construction business was conducted under unit price contracts, which contain an “escalation” clause that permits us to increase unit prices to reflect the impact of increases in the costs of labor,

10

materials and certain other items due to inflation. These unit price contracts allow flexibility in adjusting the contract price to reflect work actually performed and the effects of inflation. However, our construction contracts, and construction contracts throughout the industry, have been increasingly fixed price or not-to-exceed contracts, under which we are committed to provide materials or services at fixed unit prices, including our two major raw material requirements—cement and steel. Fixed price and not-to-exceed contracts shift the risk of any increase in our unit cost over our unit bid price to us. See “Item 4. Information on our Company—Business Overview—Description of Business Segments—Construction—Contracting Practices.”

In the past we experienced significant losses due to risks assumed by us in fixed price and not-to-exceed contracts, and we may face similar difficulties in the future. For example, a number of our construction contracts specify fixed prices for various raw materials and other inputs necessary for the construction business, including steel, asphalt, cement, construction aggregates, fuels and various metal products. Increased prices of these materials can negatively affect our results if we are unable to transfer the risk to the client. Under the terms of many of our fixed price contracts, we have been required to bear the cost of the increases in the cost of raw materials from the time we entered into the contracts, which has adversely affected our results of operations and liquidity. While we may enter into long term contracts with certain providers of cement and steel for the life of some of our larger projects, we have generally relied on purchases from various suppliers. Prices for various steel products increased significantly between 2003 and 2008, we believe due in part to a decrease in production and global consumption because of the global financial crisis, but stabilized beginning in 2009, which continued through 2015. Despite a significant depreciation in the Mexican peso, steel prices have fluctuated between +/-5% mainly because of the low demand for steel in Mexico caused by a slower pace in the construction and infrastructure projects. Although we seek to negotiate for the recovery of the increase in the cost of raw materials in our contracts whenever possible, we cannot assure you that we will be successful in recovering any portion of these cost increases, which will negatively affect our operating margins.

We may also experience other construction and administrative cost overruns, including as a result of incorrect contract specifications that we are unable to pass on to the customer. We expect that, because of conditions attendant to financing arrangements, future concession-related, infrastructure and industrial construction contracts may not permit an adjustment of the contract price for additional work done due to incorrect project specifications and, as a result, our operating margins and liquidity would be negatively affected. Additionally given that our clients have increased regulation related to project variations, we may not be able to recover for these changes in our civil construction projects. See “Item 5. Operating and Financial Review and Prospects—Operating Results—Construction—Civil Construction.”

Our backlog is subject to unexpected adjustments and cancellations and, therefore, may not be a reliable indicator of our future revenue or earnings.

Our backlog is not necessarily indicative of our future operating revenues or earnings related to the performance of the underlying work. Our backlog, which represents our expected revenues under signed contracts, is often subject to revision over time. We cannot guarantee that our backlog will be realized or profitable or that we will secure contracts equivalent in scope and duration to replace current backlog. Project cancellations, scope adjustments or deferrals may occur, from time to time, due to various factors including but not limited to commercial issues, regulatory requirements and adverse weather. Such developments could have a material adverse effect on our business and our profits. See “Item 5. Operating and Financial Review and Prospects—Operating Results—Construction—Construction Backlog.”

Our participation in projects and other operations, particularly including our participation in joint ventures and affiliates, or acquisitions, outside Mexico involves greater and different risks than those typically faced in Mexican projects and could jeopardize our profits.

To date, our foreign projects and operations in Latin America and elsewhere have generated negative to mixed results. We have experienced significant losses on projects in Latin America and elsewhere in the past. There can be no assurance that our projects outside of Mexico will be successful, which would jeopardize profits.

11

Our operations in markets outside of Mexico expose us to several risks, including risks from changes in foreign currency exchange rates, interest rates, inflation, governmental spending, social instability and other political, economic or social developments that may materially reduce our net income.

Our hedging contracts may not effectively protect us from financial market risks including exchange rate risk and may negatively affect our cash flow.

Our activities are exposed to various financial market risks (such as risks related to interest rates, exchange rates and prices). One strategy we use to attempt to minimize the potential negative effects of these risks on our financial performance is to enter into derivative financial instruments to hedge our exposure to such risks with respect to our recognized and forecasted transactions and our firm commitments.

We have entered into various types of hedges, including with respect to foreign currency exposure, and other trading derivative instruments for the terms of some of our credit facilities with the objective of reducing the uncertainties resulting from interest rate and exchange rate fluctuations. To date, our derivative financial instruments have had mixed results. Their marked-to-market valuation as of December 31, 2015 decreased our derivative liabilities by Ps.46 million and decreased our derivative assets by Ps. 937 million.

The contract amounts for our derivative financial instruments are generally based on our estimates of cash flows for a project as of the date we execute the derivative. As actual cash flows may differ from estimated cash flows, we cannot assure you that our derivative financial instruments will protect us from the adverse effects of financial market risks. See “—Risks Related to Mexico and Other Markets in Which We Operate—Appreciation or depreciation of the Mexican peso relative to the U.S. dollar, other currency fluctuations and foreign exchange controls could adversely affect our financial condition and results of operations.” The use of derivative financial instruments may also generate obligations for us to make additional cash payments, which would negatively affect our liquidity. See “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Derivative Financial Instruments.”

A substantial percentage of our cash and cash equivalents is held through less-than-wholly owned subsidiaries, or in reserves, that restrict our access to them.

As of December 31, 2015, we had total cash and cash equivalents of Ps. 9,289 million, of which Ps. 4,473 million was restricted, as compared to Ps. 3,513 million of restricted cash as of December 31, 2014. Restricted cash is presented as a separate line item in our statement of financial position. As of December 31, 2015, we held Ps. 5,058 million that represent 54% of our consolidated cash and cash equivalents (including restricted cash) through less-than-wholly owned subsidiaries (including 29% in the Airports segment, 10% in the Kantunil–Cancun toll road, 6% in Rio Verde-Ciudad Valles Highway and 5% in Acapulco Tunnel among others). Approximately Ps. 4,231 million, the remainder of our total cash and cash equivalents as of December 31, 2015, was held in our parent company EMICA or in other operating subsidiaries.

A portion of our cash and cash equivalents are held in reserves established to secure financings. These resources form part of our restricted cash, mentioned above, as presented in our statement of financial position. At December 31, 2015, Ps. 4,039 million, or 43%, of our cash and cash equivalents were held in reserves established to secure financings, including any related expenses, principally in connection with the following projects: the SPC Projects, the Acapulco Tunnel, the Kantunil–Cancun Toll Road, Rio Verde-Ciudad Valles Highway, the La Piedad bypass and the Palmillas-Apaseo El Grande Toll Road, all of which are restricted. The reserve requirements of such financings could also limit our access to liquid resources and limit our ability to decide when to use our cash and cash equivalents.

Additionally, some uses of cash and cash equivalents by certain of our less than wholly-owned subsidiaries require the consent of the other shareholders or partners, as applicable, of such subsidiary, such as Caisse de depot et placement du Quebec or (CDPQ) in the case of ICA OVT Constructora Meco S.A. in the case of the Domingo Diaz project in Panama, and Promotora del Desarrollo de America Latina, S.A. de C.V., in the case of Scenic Bypass project in Acapulco. While the cash held in these entities is not designated for a specific use or set aside as a compensating balance, the requirements for its use could limit our access to liquid resources or limit us from freely deciding when to use cash and cash equivalents outside of normal operations.

12

A significant portion of our assets are pledged under financing arrangements.

Portions of our assets are pledged to a number of banks under credit arrangements, including: Credit Suisse AG, Cayman Islands Branch, Global Bank Corporation; Banco Inbursa, BBVA Bancomer Institución de Banca Multiple, Grupo Financiero BBVA Bancomer; Banco Mercantil de Norte, S.A. Grupo Financiero Banorter; Bancodel Bajo, S.A, Banco Nacional de Obras y Servicios Publicos, S.N.C; Bancolombia, S.A., Deutsche Bank AG, London Branch; Interamerican Credit Corporation and Sociedad Hipotecaria Federal. The assets we have pledged include collection rights under construction contracts, concessions, construction machinery and equipment, real property, dividend rights and shares of each of our financed concession projects. Notably among these, we have pledged, Autovia Necaxa-Tihuatlan, S.A. de C.V., (“Auneti”), our joint venture that operates the Nuevo Necaxa-Tihuatlan highway, our 50% interest in Los Portales, S.A., a real estate associate located in Peru, our interest in the El Realito project, our interest in the Agua Prieta project, our shares of Autopista Naucalpan Ecatepec, S.A. de C.V., (“ANESA”), the contractor for the Rio de los Remedios-Ecatepec toll highway project, as well as the collection rights of the Rio de Los Remedios-Ecatepec project and Palmillas-Apaseo El Grande toll road Apaseo El Grande Toll Road. In general, assets securing credit arrangements will remain pledged until the arrangement secured by these assets expire. As a result of these arrangements, our ability to dispose of pledged assets requires the consent of these banks and our ability to incur further debt (whether secured or unsecured) is limited. In 2015, Deutsche Bank foreclosed on certain of our shares in GACN and subsequently, during 2016, we have reached agreements with other secured parties regarding foreclosure on additional shares in GACN.

We may have difficulty obtaining the letters of credit and performance bonds that we require in the normal course of our operations.

Historically, our clients have required us to obtain bonds to secure, among other things, bids, and performance, or to make advance payments. In recent years, however, our clients, including the Mexican Federal Electricity Commission (Comision Federal de Electricidad), the Mexican Ministry of Communication and Transportation, and Petroleos Mexicanos, or Pemex, and foreign clients, have increasingly required letters of credit and other forms of guarantees to secure such bids, to advance payments and to guarantee performance. As a result of our financial condition, we have found it difficult to obtain the performance bonds or letters of credit necessary to perform the large infrastructure projects in Mexico and abroad that historically have generated a substantial majority of our revenues. We cannot assure you that in the future we will not find it difficult to obtain performance bonds or letters of credit as lenders generally have reduced the credit they extend to us for bonding and our access to new sources of letters of credit and bonding for our construction projects is restricted as a result of our current defaults. Our ability to provide additional letters of credit and other forms of collateralized guarantees is limited, which may impact our ability to participate in projects in the future.

The nature of our engineering and construction business exposes us to potential liability claims and contract disputes, which may reduce our profits.

We engage in engineering and construction activities for large facilities where design, construction or systems failures can result in substantial injury or damage to third parties or our clients and result in reputational damage to us. We have been and may in the future be named as a defendant in legal proceedings where third parties or our clients may make a claim for damages or other remedies with respect to our projects or other matters. These claims generally arise in the normal course of our business. We are currently involved in litigation related to alleged defects in construction of Line 12 of the Mexico City metro system. See “Item 8. Financial Information—Legal and Administrative Proceedings—Line 12 of the Mexico City Metro.” When it is determined that we have a liability, we may not be covered by insurance or, if covered, the dollar amount of these liabilities may exceed our policy limits. In addition, even where insurance is maintained for such exposures, the policies have deductibles resulting in our assuming exposure for a layer of coverage with respect to any such claims. Any liability not covered by our insurance, in excess of our insurance limits or, if covered by insurance but subject to a high deductible, could result in a significant loss for us, which may reduce our profits and cash available for operations.

13

We have increasingly been required to meet minimum equity requirements, financial ratios or more stringent experience requirements and obtain transaction ratings in order to bid on large public infrastructure projects, which could reduce our ability to bid for potential projects.

In recent years, we have increasingly been required to meet minimum equity requirements, certain financial ratios or more stringent experience requirements (particularly in international biddings) and obtain transaction ratings on our financial proposals from a recognized rating agency in order to bid on large public infrastructure projects. For example, Pemex, Mexico’s state-owned oil company, has increasingly required that companies that submit bids for certain of its public projects meet minimum equity requirements. Similarly, Mexico City’s government has increasingly required that companies submitting bids for its public works projects meet minimum financial ratios. The levels and types of ratios vary substantially. We cannot assure you that we will be able to comply with such during our restructuring or in the future. If we do not meet such requirements, it could impair our ability to bid for potential projects, which would have an adverse effect on our financial condition and results of operations.

We are subject to Mexico’s anti-corruption laws and the U.S. Foreign Corrupt Practices Act. Our failure to comply with these laws could result in penalties, which could harm our reputation and have an adverse effect on our business, results of operations and financial condition.

We are subject to Mexican and international anti-corruption laws, including the U.S. Foreign Corrupt Practices Act, or the FCPA, which generally prohibits companies and anyone acting on their behalf from offering or making improper payments or providing benefits to government officials for the purpose of obtaining or keeping business. Transparency International, an international organization that reviews potential governmental and institutional corruption, has rated the construction industry and many of the countries in which we operate poorly in terms of corruption risk. As part of our construction business, we often bid for projects run by or related to government-owned enterprises or government ministries, departments and agencies, or require governmental authorizations to perform work. We are thus in frequent contact with persons who may be considered “foreign officials” under the FCPA, resulting in an elevated risk of potential FCPA violations.

We maintain policies and procedures that require our employees to comply with anti-corruption laws, including the FCPA, and our corporate standards of ethical conduct. However, we cannot ensure that these policies and procedures will always protect us from intentional, reckless or negligent acts committed by our employees or agents. If we are not in compliance with the FCPA and other applicable anti-corruption laws, we may be subject to criminal and civil penalties and other remedial measures, which could have an adverse impact on our business, financial condition, and results of operations. Any investigation of any potential violations of the FCPA or other anti-corruption laws by U.S. or other governmental authorities, including Mexican authorities, could adversely impact our reputation, cause us to lose or become disqualified from bids, and lead to other adverse impacts on our business, financial condition and results of operations.

In 2015, the global infrastructure industry was subject to increasing anticorruption scrutiny, implicating some of the biggest companies in the industry.

Our business may evolve through foreign or domestic mergers, acquisitions or divestitures which may pose risks or challenges.

Our Board of Directors and management may from time to time engage in discussions regarding possible strategic transactions, including merger, acquisition or divestment transactions with third parties and other alternatives, for the purpose of strengthening our position or restructuring our company. However, there can be no assurance that we will be able to successfully identify, negotiate and complete any such strategic transactions. In addition, if we complete a strategic transaction, the implementation of such transaction will involve risks, including the risks that we will not realize the expected benefits of such transaction, that we may be required to incur non-recurring costs or other charges and that such transaction may result in a change in control. In addition, certain strategic transactions must be approved by our stockholders or Board of Directors, depending upon their materiality, and may require, among other things, approval from governmental agencies.

14

The success of our strategic alliances depends on the satisfactory performance by our alliance partners of their joint venture obligations. The failure of our alliance partners to perform their joint venture obligations could impose on us additional financial and performance obligations that could result in reduced profits or, in some cases, significant losses for us with respect to the alliance.

We enter into various joint ventures, associations and other strategic alliances and collaborations as part of our engineering, procurement, construction and infrastructure businesses, including ICA Fluor, Los Portales, and Actica Sistemas S. de R.L. de C.V., or Actica, as well as project-specific joint ventures, including the Eastern Discharge Tunnel, On April 13, 2015, we entered into an agreement with the Caisse de dépôt et placement du Québec to sell a 49% stake in our subsidiary ICA Operadora de Vías Terrestres, S.A.P.I. de C.V. (“ICA OVT”), created on March 19, 2015, which owns the concessions for Consorcio del Mayab, S.A. de C.V., ICA San Luis, S.A. de C.V., Libramiento La Piedad, S.A. de C.V. and Túneles Concesionados de Acapulco, S.A. de C.V. The success of these and other joint ventures depends, in part, on the satisfactory performance by our joint venture partners of their joint venture obligations. If our joint venture partners fail to satisfactorily perform their joint venture obligations as a result of financial or other difficulties, the joint venture may be unable to adequately perform or deliver its contracted services. Under these circumstances, we may be required to make additional investments and provide additional services to ensure the adequate performance and delivery of the contracted services. These additional obligations could result in reduced profits or, in some cases, significant losses for us with respect to the joint venture. We cannot assure you that our business partnerships or joint ventures will be successful in the future.

Our current financial constraints, our defaults on our debt instruments, including those related to certain of our joint ventures may cause us to divest of revenue generating businesses or deconsolidate them due to change of control provisions.

We cannot assure you that we will not be forced to decrease our holdings in our joint ventures or fully divest them. For example, our acquisition of San Martin required certain payments over time and our inability to make such payments when due resulted in the sale of our controlling interest in that company. We now own a non-controlling interest and may further decrease our holding due to our default on a loan guaranteed by our shares in this entity.

If we are unable to form teaming arrangements, our ability to compete for and win certain contracts may be negatively impacted.

In both the private and public sectors, either acting as a prime contractor, a subcontractor or as a member of a team, we may join with other firms to form a team to compete for a single contract, especially in projects located outside of Mexico, where we may seek local experience, or involving a more complex technical and/or financial structure. Because a team can offer stronger combined qualifications than a firm standing alone, these teaming arrangements can be important to the success of a particular contract bid process or proposal. The failure to maintain such relationships in certain markets, such as the government market, may impact our ability to win work.

We face risks related to project performance requirements and completion schedules, which could jeopardize our profits.

In certain instances, we have guaranteed completion of a project by a scheduled acceptance date or achievement of certain acceptance and performance testing levels. However, there is a risk that adherence to these guarantees may not be possible. Additionally, under certain Mexican laws, public officials may be held personally liable for decisions made in their professional capacities, and as a result officials who oversee our projects may not make decisions, such as executing change orders, required for progress of our projects. We are currently involved in litigation with the Mexico City government related to alleged defects in construction of Line 12 of the Mexico City metro system. See “Item 8. Financial Information—Legal and Administrative Proceedings—Line 12 of the Mexico City Metro.” The failure to meet any schedule or performance requirements for any reason could result in costs that exceed projected profit margins, including fixed-amount liquidated damages up to a certain percentage of the overall contract amount and/or guarantees for the entire contract amount. We cannot assure you that the financial penalties stemming from the failure to meet guaranteed acceptance dates or achievement of acceptance and performance testing levels would not have an adverse effect on our reputation, financial condition and results of operations.

Our return on our investment in a concession project may not meet the originally estimated returns.

Our return on any investment in any concession (including highway, social infrastructure, tunnel or wastewater treatment concessions) is based on the duration of the concession and the amount of capital invested, in addition to the amount of usage revenues collected, debt service costs and other factors. For example, traffic volumes, and thus toll revenues, are affected by a number of factors including toll rates, the quality and proximity of alternative free roads, fuel prices, taxation, environmental regulations, consumer purchasing power and general economic conditions. The level of traffic on a given highway also is influenced heavily by its integration into other road networks. Usually concession and Public-Private Partnership, or PPP, contracts provide that the grantor of the contract shall deliver the right-of-way to the project land in accordance with the construction schedule. If the grantor fails to deliver such rights-of-way on time, we may incur additional investments and delays at the start of operations, and therefore we may need to seek the modification of the concession or PPP contract. We cannot assure you that we will reach an agreement as to the amendment of any such contracts or that the grantor will honor its obligations thereunder. Particularly for new projects in which we take on construction risk, overruns of budgeted costs may create a higher capital investment base than expected, and therefore a lower return on capital. Given these factors, we cannot assure you that our return on any investment in a concession will meet the estimates contemplated in the relevant concession or PPP contract.

Governments may terminate our concessions under various circumstances, some of which are beyond our control.

Our concessions are among our principal assets, and we would be unable to continue the operations of a particular concession without the concession right from the granting government. A concession may be revoked by a government for certain prescribed reasons pursuant to the particular title and the particular governing law, which may include failure to comply with development and/or maintenance programs, temporary or permanent halt in our operations, failure to pay damages resulting from our operations, exceeding our maximum authorized rates or failure to comply with any other material term of a concession.

In particular, the Mexican government may also terminate a concession at any time through reversion, if, in accordance with applicable Mexican law, it determines that it is in the public interest to do so. The Mexican government may also assume the operation of a concession in the event of war, public disturbance or threat to national security. In addition, in the case of a force majeure event, the Mexican government may require us to implement certain changes in our operations. In the event of a reversion of the public domain assets that are the subject of our concessions, the Mexican government under Mexican law is generally required to compensate us for the value of the concessions or added costs. Similarly, in the event of an assumption of our operations, other than in the event of war, the government is required to compensate us and any other affected parties for any resulting damages. Other governments often have similar provisions in their concession contracts and applicable law. We cannot assure you that we would receive such compensation on a timely basis or in an amount equivalent to the value of our investment in a concession and lost profits.

Our failure to recover adequately on claims or change orders against project owners for payment could have a material adverse effect on us.

We may bring claims against project owners for additional costs that exceed the contract price or for amounts not included in the original contract price, including change orders. These types of claims occur due to matters such as owner-caused delays, increased unit prices or changes from the initial project scope that result, both directly and indirectly, in additional costs. Often, these claims can be the subject of lengthy arbitration, litigation or third-party expert proceedings, and it can be difficult to accurately predict when these claims will be fully resolved. When these types of events occur and unresolved claims are pending, we may invest significant working capital in projects to cover cost overruns pending the resolution of the relevant claims. With respect to change orders in particular, we may agree on the scope of work to be completed with a client without agreeing on the price, and in this case we may be required to use a third-party expert to set the price for the change order. We do not have control over such third-party experts and they may make price determinations that are unfavorable to us. As of December 31, 2015, we had Ps. 6,672 million of allowance for doubtful accounts related to contract and trade receivables, including an allowance for doubtful accounts in the Civil Construction segment related to the Line 12 of the Mexico City metro system project, Barranca Larga in Oaxaca and Lazaro Cardenas Port Terminal in

16

Michoacan,. See “Item 8. Financial Information—Legal and Administrative Proceedings—Line 12 of the Mexico City Metro.” A failure to promptly recover on these types of claims and change orders could have a material adverse effect on our liquidity and financial condition. As of December 31, 2015, we created reserves for doubtful accounts receivable in the amount of Ps.5,380 in the Civil Construction Segment related to Barranca Larga, Terminal de Contenedores and Corredor Norte, as related to certain claims and unbilled but executed works.

Our operational stability during the restructuring and potential growth in the future will require us to hire and retain qualified personnel. If we lose key members of our management team and are unable to attract other qualified personnel, our business could be adversely affected.

Over the past years, the demand for employees who engage in and are experienced in the services we perform has continued to grow as other competitors enter the market, and as a result of the structural legal reforms related to the oil and gas industry. Although we significantly reduced our overall workforce in 2015 and continue to do so in connection with asset sales and our cost reduction plan, our current projects and our continuing obligations require us to retain employees. Our successful restructuring is also dependent upon being able to attract and retain personnel, including engineers, corporate management and craft employees, who have the necessary and required experience and expertise. Competition for this kind of personnel is intense and our reputation in the marketplace related to the restructuring and the corresponding reduction in workforce may affect our ability to compete. Difficulty in attracting and retaining these personnel could reduce our capacity to perform adequately in present projects and to bid for new ones.

We maintain a workforce based upon current and anticipated workloads. If we do not receive future contract awards or if these awards are delayed, we may incur significant costs.

Our estimates of future performance depend on, among other matters, whether and when we will receive certain new contract awards. While our estimates are based upon our good faith judgment, these estimates can be unreliable and may frequently change based on newly available information. As of December 31, 2015, the number of employees in our workforce decreased by 9,188 employees as compared to December 31, 2014, based on decreased expectations for future projects in the near term, resulting in additional costs under Mexican labor law related to these reductions. In the case of large-scale domestic and international projects where timing is often uncertain, it is particularly difficult to predict whether and when we will receive a contract award. The uncertainty of contract award timing can present difficulties in matching our workforce size with our contract needs. If an expected contract award is delayed or not received or if as a result of the current restructuring we need to continue to reduce our workforce, Mexican labor law requirements could cause us to incur costs resulting from reductions in workforce or redundancy of facilities that would have the effect of reducing our profits.

Risks Related to Our Airport Operations

Our Airport segment’s operating income and net income are dependent on our subsidiary GACN, and GACN’s revenues are closely linked to passenger and cargo traffic volumes and the number of air traffic movements at its airports.

We operate 13 concessioned airports in Mexico through Grupo Aeroportuario del Centro Norte, S.A. de C.V. (“GACN”). As of December 31, 2015, we controlled shares representing approximately 37.5% of GACN’s capital stock. Our interest in GACN exposes us to risks associated with airport operations.

In 2015, GACN represented 14% of our consolidated revenues and 32% of our operating income. GACN’s airport concessions from the Mexican government are essential to GACN’s contribution to revenues and operating income. Any adverse effect on GACN would have an adverse effect on our operating results.

Historically, a substantial majority of GACN’s revenues have been derived from aeronautical services, and GACN’s principal source of aeronautical services revenues is passenger charges. Passenger charges are payable for each passenger (other than diplomats, infants, transfer and transit passengers) departing from the airport terminals we operate, collected by the airlines and paid to GACN. In 2015, 2014 and 2013, passenger charges represented 55.6%, 55.5%, and 54.2%, respectively, of GACN’s total revenues. GACN’s revenues are thus closely linked to

17

passenger and cargo traffic volumes and the number of air traffic movements at its airports. These factors directly determine GACN’s revenues from aeronautical services and indirectly determine its revenues from non-aeronautical services. Passenger and cargo traffic volumes and air traffic movements depend in part on many factors beyond our control, including economic conditions in Mexico, the U.S. and the world, the political situation in Mexico and elsewhere in the world, high incidences of crime, particularly related to drug trafficking, throughout Mexico but especially in the northern cities, the attractiveness of GACN’s airports relative to that of other competing airports, fluctuations in petroleum prices (which can have a negative impact on traffic as a result of fuel surcharges or other measures adopted by airlines in response to increased fuel costs) and changes in regulatory policies applicable to the aviation industry. International conflicts and health epidemics, such as the Influenza A(H1N1) epidemic, and the Ebola crisis, Zika and Chikungunya, have negatively affected the frequency and pattern of air travel worldwide. The future occurrence or worsening of any of such developments going forward would adversely affect GACN’s business, and in turn, our business. Any decreases in passenger and cargo traffic volumes and the number of air traffic movements to or from our airports as a result of these factors could adversely affect GACN’s business, results of operations, prospects and financial condition, thereby negatively affecting our overall results.

Terrorist attacks have had a severe impact on the international air travel industry, and terrorist attacks and other international events have adversely affected GACN’s business and may do so in the future.

As with all airport operators, GACN is subject to the threat of terrorist attack. The terrorist attacks on the United States on September 11, 2001 had a severe adverse impact on the air travel industry, particularly on U.S. carriers and on carriers operating international service to and from the United States. Airline traffic in the United States fell precipitously after the attacks. GACN’s terminal passenger volumes declined 5.8% in 2002 as compared to 2001. Any future terrorist attacks involving one of GACN’s airports, whether or not involving aircraft, will likely adversely affect our business, results of operations, prospects and financial condition. Among other consequences, airport operations would be disrupted or suspended during the time necessary to conduct rescue operations, investigate the incident and repair or rebuild damaged or destroyed facilities, and our future insurance premiums would likely increase. In addition, GACN’s insurance policies do not cover all losses and liabilities resulting from terrorism. Any future terrorist attacks, whether or not involving aircraft, will likely adversely affect GACN’s business, results of operations, prospects and financial condition.

Because a substantial majority of GACN’s international flights involve travel to the U.S., it may be required to comply with security directives of the U.S. Federal Aviation Authority, in addition to the directives of Mexican aviation authorities. The International Civil Aviation Organization, an agency of the United Nations Organization, established security guidelines requiring checked baggage on all international commercial flights as of January 2006, and all domestic commercial flights as of July 2006, to undergo a comprehensive screening process for the detection of explosives; on May 1, 2014, the Mexican Bureau of Civil Aviation published similar guidelines. Security measures taken to comply with future security directives or in response to a terrorist attack or threat could reduce passenger capacity at GACN’s airports due to increased passenger screening and slower security checkpoints, as well as increase our operating costs, which would have an adverse effect on GACN’s business, results of operations, prospects and financial condition. Recent world events such as the terrorist attacks in Paris and Brussels and other attacks attributed to the Islamic State of Iraq and Syria or any other organization could lead to additional security measures taken by the FAA or the ICAO and could require GACN to incur additional costs to comply with these measures. Similarly, GACN’s airport operations and passenger volume could be negatively impacted by terrorist attacks on aircrafts, such as those which occurred with international airlines’ aircraft operating over Egypt and the Ukraine in 2015.

Other international events such as the conflicts in the Middle East and public health crises such as the Severe Acute Respiratory Syndrome, or SARS crisis and the Influenza A(H1N1) crisis, the Ebola crisis, Zika and Chikungunya have, in the past, negatively affected the frequency and pattern of air travel worldwide. Because GACN’s revenues are largely dependent on the level of passenger traffic in its airports, any general increase of hostilities relating to reprisals against terrorist organizations, further conflict in the Middle East, outbreaks of health epidemics such as SARS, Influenza A(H1N1) and, Ebola, Zika and Chikungunya,or other international events of general concern (and any related economic impact of such events) could result in decreased passenger traffic and increased costs to the air travel industry and, as a result, could cause a material adverse effect on GACN’s business, results of operations, prospects and financial condition.

18

Variations in international fuel prices could directly or indirectly affect GACN’s business and results from operations.

Although international fuel prices, which represent a significant cost for airlines using GACN’s airports, have decreased in recent months, in the past, increased costs were among the factors leading to cancellations of routes, decreases in frequencies of flights, and in some cases even contributed to filings for bankruptcy by some airlines. Likewise, recent decreases in international fuel prices have led to budgetary cuts in Mexico, affecting economic growth and consumer spending. Any substantial variation in fuel prices could have an adverse effect on GACN’s results of operations and financial condition.

GACN provides a public service regulated by the Mexican government and its flexibility in managing its aeronautical activities is limited by the regulatory environment in which it operates.

GACN operates its airports under concessions, the terms of which are regulated by the Mexican government. As with most airports in other countries, GACN’s aeronautical fees charged to airlines and passengers are regulated. In 2015, 2014 and 2013, approximately 67.5%, 67.9% and 66.4%, respectively, of GACN’s total revenues were earned from aeronautical services, which are subject to price regulation under its maximum rates. These regulations may limit GACN’s flexibility in operating its aeronautical activities, which could have a material adverse effect on its business, results of operations, prospects or financial condition. In addition, several of the regulations applicable to GACN’s operations and that affect its profitability are authorized (as in the case of its master development programs) or established (as in the case of its maximum rates) by the Ministry of Communications and Transportation for five-year terms. We generally do not have the ability to unilaterally change GACN’s obligations (such as the investment obligations under its master development programs or the obligation under its concessions to provide a public service) or increase its maximum rates applicable under those regulations should passenger traffic or other assumptions on which the regulations were based change during the applicable term. In addition, this price regulation system may be amended in the future in a manner that would cause additional sources of GACN’s revenues to be regulated, which could limit GACN’s flexibility in setting prices for additional sources of revenues that are not currently subject to any restriction.

We cannot predict how the regulations governing our Airports segment will be applied.

Many of the laws, regulations and instruments that regulate our airport business were adopted or became effective in 1999, and there is only a limited history that would allow GACN to predict the impact of these legal requirements on GACN’s future operations. In addition, although Mexican law establishes ranges of sanctions that might be imposed should GACN fail to comply with the terms of one of its concessions, the Mexican Airport Law (Ley de Aeropuertos) and its regulations or other applicable law, we cannot predict the sanctions that are likely to be assessed for a given violation within these ranges. We may encounter difficulties in complying with these laws, regulations and instruments.

Although GACN’s master development programs and maximum rates through 2000 have been set, we cannot predict what GACN’s master development plan for 2021 and the following years will establish. When determining GACN’s maximum rates for the next five-year period (covering 2021 to 2025), the Ministry of Communications and Transportation may be subject to significant pressure from different entities (for example, the Mexican Federal Competition Commission (Comisión Federal de Competencia) and the carriers operating at GACN’s airports) to modify GACN’s maximum rates, which may reduce the profitability of our airport business. The laws and regulations governing our airport business, including the rate-setting process and the Mexican Airport Law, may change in the future or be applied or interpreted in a way that could have a material adverse effect on GACN’s business, results of operations, prospects and financial condition.

Additionally, the Ministry of Communications and Transportation has announced that it intends to establish a new, independent regulatory agency, the Federal Agency of Civil Aviation, that is expected to serve a role similar to that of the Mexican Bureau of Civil Aviation (Dirección General de Aeronáutica Civil) of establishing, coordinating, overseeing and controlling international and national air transportation, as well as overseeing the airports, complementary services and generally all activities related to civil aviation. We cannot predict whether or when this new agency will be organized, the scope of its authority, the actions that it will take in the future or the effect of any such actions on our business.

19

The Mexican government could grant new concessions that compete with our airports and could have an adverse effect on our revenues.

The Mexican government could grant additional concessions to operate existing government managed airports or authorize the construction of new airports, which could compete directly with our airports. Any competition from other such airports could have a material adverse effect on GACN’s business and results of operations. Under certain circumstances, the grant of a concession for a new or existing airport must be made pursuant to a public bidding process. In the event that a competing concession is offered in a public bidding process, we may not participate in such process, or we may not be successful if we were to participate.

Our operations depend on certain key airline customers, and the loss of or suspension of operations of one or more of them could result in a loss of a significant amount of our revenues.

Of the total aeronautical revenues generated at GACN’s airports in 2015, Aerovias de Mexico, S.A. de C.V., or Aeromexico, and its affiliates accounted for 28.3%, VivaAerobus represented 16.3%, Interjet represented 17.5% and Volaris represented 12.1%.

None of GACN’s contracts with its airline customers obligate them to continue providing service from GACN’s airports and if any of GACN’s key customers reduced their use of GACN’s airports, competing airlines may not add flights to their schedules to replace any flights no longer handled by GACN’s principal airline customers. Our business and results of operations could be adversely affected if we do not continue to generate comparable portions of our revenue from our key customers.

In addition, Mexican law prohibits an international airline from transporting passengers from one Mexican location to another (unless the flight originated outside Mexico), which limits the number of airlines providing domestic service in Mexico. Accordingly, GACN expects to continue to generate a significant portion of its revenues from domestic travel from a limited number of airlines.

Due to increased competition, volatility in fuel prices and the general decrease in demand consequent to the global volatility in the financial and exchange markets and economic crisis, many airlines are operating in adverse conditions. Should fuel prices increase or in the event of other adverse economic developments one or more of GACN’s principal carriers could become insolvent, cancel routes, suspend operations or file for bankruptcy. All such events could have a material adverse effect on GACN’s results of operations.

The operations of GACN’s airports may be affected by the actions of third parties, which are beyond our control.

As is the case with most airports, the operation of GACN’s airports is largely dependent on the services of third parties, such as air traffic control authorities, airlines and providers of catering and baggage handling. GACN is also dependent upon the Mexican government or government entities for provision of services, such as electricity, supply of fuel to aircraft, air traffic control and immigration and customs services for international passengers. The disruption or stoppage of taxi or bus services at one or more of GACN’s airports could also adversely affect GACN’s operations. We are not responsible for and cannot control the services provided by these parties. Any disruption in, or adverse consequence resulting from, their services, including a work stoppage, financial difficulties or other similar event, may have a material adverse effect on the operation of GACN’s airports and on GACN’s results of operations.

Risks Related to Mexico and Other Markets in Which We Operate

Adverse economic conditions in Mexico may adversely affect our business, financial condition or results of operations.

A substantial portion of our operations is conducted in Mexico and is dependent upon the performance of the Mexican economy. As a result, our business, financial condition and results of operations may be affected by the general condition of the Mexican economy, over which we have no control. See “Item 4. Information on our

20

Company—History and Development of our Company—Public Sector Spending and the Mexican Economy.” In the past, Mexico has experienced economic crises, caused by internal and external factors, characterized by exchange rate instability (including large devaluations), high inflation, high domestic interest rates, economic contraction, a reduction of international capital flows, a reduction of liquidity in the banking sector and high unemployment rates. We cannot assume that such conditions will not return or that such conditions will not have a material adverse effect on our business, financial condition or results of operations.

In 2008, GDP grew by approximately 1.8% and inflation reached 6.5%. Mexico entered into a recession beginning in the fourth quarter of 2008, and in 2009 GDP fell by approximately 6.5% and inflation was 3.6%. In 2010, GDP grew 5.5% and inflation reached 4.4%. In 2011, GDP grew by 3.9% and inflation declined to 3.8%. In 2012, GDP grew by 3.9% and inflation decreased to 3.6%. In 2013, GDP growth fell to 1.1% and inflation reached 3.97%. In 2014, GDP grew by 2.1% and inflation reached 4.0%. In 2015, GDP grew by 2.5% and inflation reached 2.13%.

Mexico also has, and is expected to continue to have, high real and nominal interest rates as compared to the United States. The annualized interest rates on 28-day Cetes averaged approximately, 3.7%, 3.0 % and 3.1% for 2013, 2014 and 2015 respectively. As of December 31, 2015, 55% of our debt is denominated in Mexican pesos, and we may continue to incur peso-denominated debt for our projects in Mexico for which the source of repayment of financing is in Mexican pesos. To the extent that we incur peso-denominated debt in the future, it could be at high interest rates compared to U.S. dollar-denominated debt.

If the Mexican economy experiences another recession, if inflation or interest rates increase significantly or if the Mexican economy is otherwise adversely impacted, our business, financial condition or results of operations could be materially and adversely affected.

Appreciation or depreciation of the Mexican peso relative to the U.S. dollar, other currency fluctuations and foreign exchange controls could adversely affect our financial condition and results of operations.

A substantial portion of our construction revenues and a substantial portion of our debt, including the Senior Notes are denominated in U.S. dollars, while the majority of our raw materials, a portion of our long-term indebtedness and a substantial portion of our purchases of machinery and day-to-day expenses, including employee compensation, are denominated in Mexican pesos. As a result, an appreciation of the Mexican peso relative to the U.S. dollar would decrease our dollar revenues when expressed in Mexican pesos. In addition, currency fluctuations may affect the comparability of our results of operations between financial periods, due to the translation of the financial results of our foreign subsidiaries.

In 2015, there was a significant depreciation in the Mexican peso against the U.S. dollar, and the noon buying rate increased to Ps. 17.3398 on December 31, 2015, representing a depreciation of approximately 17.7% compared to December 31, 2014. The Mexican peso has since further depreciated, and the noon buying rate was Ps. 18.2105 per U.S.$1.00 on May 13, 2016. Fixed price and not-to-exceed contracts require us to bear the risk of fluctuation in the exchange rate between the Mexican peso and other currencies in which our contracts, such as financing agreements, are denominated or which we may use for purchases of supplies, machinery or raw materials, day-to-day expenses or other inputs. A severe devaluation or depreciation of the Mexican peso may also result in disruption of the international foreign exchange markets and may limit our ability to transfer or to convert Mexican pesos into U.S. dollars and other currencies for the purpose of making timely payments of interest and principal on our U.S. dollar-denominated indebtedness or obligations in other currencies. While the Mexican government does not currently restrict, and since 1982 has not restricted, the right or ability of Mexican or foreign persons or entities to convert Mexican pesos into U.S. dollars or to transfer other currencies out of Mexico, the Mexican government could institute restrictive exchange control policies in the future. We cannot assure you that the Mexican Central Bank will maintain its current policy with respect to the peso. Currency fluctuations may have an adverse effect on our financial condition, results of operations and cash flows in future periods. Such effects include foreign exchange gains and losses on assets and liabilities denominated in U.S. dollars, fair value gains and losses on derivative financial instruments, and changes in interest income and interest expense. These effects can be more volatile than our operating performance and our cash flows from operations. See “—Risks Related to Our Operations—Our hedging contracts may not effectively protect us from financial market risks and may negatively affect our cash flow.”

21

Economic and political developments in Mexico could affect Mexican economic policy and adversely affect us.

Mexican governmental actions concerning the economy and state-owned enterprises could have a significant effect on Mexican private sector entities in general, and us in particular, as well as on market conditions, prices and returns on Mexican securities, including our securities. In the past, economic and other reforms have not been enacted due to legislative gridlock. Because no single party obtained a clear majority in the 2015 congressional election, governmental gridlock and political uncertainty may continue.

In December 2013, reforms to the Mexican Income Tax Law were approved for fiscal year 2014, resulting in several changes, including the elimination of the Mexican business flat tax (Impuesto Empresarial a la Tasa Unica or IETU) and the consolidation regime. See “Item 5. Operating and Financial Review and Prospects—Tax.”

In July 2013, the Federal Law for the Prevention and Identification of Transactions with Proceeds of Illicit Origin was enacted as part of the Mexican government’s strategies to combat criminal organizations and activity, including money laundering.

The law incorporates recommendations by the Financial Action Task Force on the prevention of money laundering and terrorism financing. Effective November 2013, certain of our subsidiaries, including our subsidiary ICA Planeación y Financiamiento, S.A. de C.V., SOFOM E.N.R., or ICAPLAN, are subject to additional reporting and other procedural requirements to comply with the law and implementing regulations, in particular with regard to our operations related to intercompany loans, real estate sales, and real estate leasing.

Compliance with these regulations may be burdensome and could result in increased costs. Additionally, if as a result of the more stringent requirements under the new law we are associated with, or accused of being associated with, or become a party to, money laundering and/or terrorism financing, then our reputation could suffer and/or we could become subject to fines, sanctions and/or legal enforcement, any one of which could have a material adverse effect on our operating results, financial condition and prospects.

The timing and scope of modifications such as the above are unpredictable, which can adversely affect our ability to manage our tax or other planning and, as a result, negatively affect our business, financial condition and results of operation.

Security risks may negatively affect our business, specifically with regards to our user-number based projects located in regions with increased security risk.

We have projects located in regions with recently increased security risks that may affect the revenues of projects based on number of users, such as our toll road, tunnel and airport concessions.

Additionally, home sales in low-income housing depend substantially on purchasers’ access to credit through the Institution for Worker’s Housing (Instituto del Fondo Nacional de la Vivienda para los Trabajadores, or Infonavit), a public funding agency. An increase in drug-related offenses and other crime has led to higher vacancy rates in housing developments in the northern border states of Mexico. As a result, it is possible that Infonavit may restrict grants or disbursements of housing credit in northern cities.

Developments in other countries could adversely affect the Mexican economy, our business, financial condition or results of operations and the market value of our securities.

The Mexican economy, the business, financial condition or results of operations of Mexican companies and the market value of securities of Mexican companies may be, to varying degrees, affected by economic, geopolitical and market conditions in other countries. Although economic conditions in other countries may differ significantly from economic conditions in Mexico, investors’ reactions to adverse developments in other countries may have an adverse effect on the market value of securities of Mexican issuers. In recent years, economic conditions in Mexico

22

have become increasingly correlated with economic conditions in the United States as a result of NAFTA and increased economic activity between the two countries. In the second half of 2008, the prices of both Mexican debt and equity securities decreased substantially as a result of the prolonged decrease in the United States securities markets. This general correlation continued in 2011 and 2012. However, in the first quarter of 2013 the Mexican economy declined while the U.S. economy improved. For example, during 2014 and 2015 the U.S. securities market trended upward while the Mexican market oscillated at a stable rate. Nonetheless, adverse economic conditions in the United States, the termination of NAFTA or other related events or geopolitical events with global repercussions could have a material adverse effect on the Mexican economy. However, Mexico may not, and has not, uniformly benefited from the strengthening of the U.S. economy. The Mexican debt and equities markets also have been adversely affected by ongoing developments in the global credit markets. We cannot assure you that events in other emerging market countries, in the United States or elsewhere will not materially adversely affect our business, financial condition or results of operations.

Corporate disclosure in Mexico may differ from disclosure regularly published by or about issuers of securities in other countries, including the United States.

A principal objective of the securities laws of the United States, Mexico, and other countries is to promote full and fair disclosure of all material corporate information, including accounting information. However, there may be different or less publicly available information about issuers of securities in Mexico than is regularly made available by public companies in countries with highly developed capital markets, including the United States.

Risks Related to our Securities and our Major Shareholders

We have been notified by the New York Stock Exchange that the average trading price of our ADSs does not meet the New York Stock Exchange’s continued listing requirements.

The New York Stock Exchange requires a certain minimum average trading price over a thirty-day period. On January 8 2016, we were notified by the New York Stock Exchange that the average trading price of our ADSs did not meet the New York Stock Exchange’s continued listing requirements. We may not be able to comply with or remedy the average trading price in order to continue trading after the cure period for doing so expires. If we are unable to comply with the NYSE’s trading price requirements, the NYSE may suspend our ADSs from trading.

You may not be entitled to participate in future preemptive rights offerings.

In a public offering, pursuant to Article 53 of the Mexican Securities Market Law, we are not required to grant preemptive rights to any holders of our ADSs, Ordinary Participation Certificates, or CPOs, or shares. We are not required by law to undertake our capital increases using public offerings.

If we issue new shares for cash in a private offering, as part of a capital increase, we must grant our stockholders the right to purchase a sufficient number of shares to maintain their existing ownership percentage in our company. Rights to purchase shares in these circumstances are known as preemptive rights. However, we are not legally required to grant holders of ADSs, CPOs or shares in the United States any preemptive rights in any future private offering.

To allow holders of ADSs in the United States to participate in a private preemptive rights offering, we would have to file a registration statement with the Securities and Exchange Commission or conduct an offering that qualified for an exemption from the registration requirements of the Securities Act of 1933, as amended. We cannot assure you that we would do so. At the time of any future capital increase, we will evaluate the costs and potential liabilities associated with filing a registration statement with the Securities and Exchange Commission, as well as any other factors that we consider important to determine whether we will file such a registration statement. In addition, under current Mexican law, sales by the depository of preemptive rights and distribution of the proceeds from such sales to you, the ADS holders, is not possible.

The significant share ownership of our management and members of our Board of Directors, coupled with their rights under the bylaws, may have an adverse effect on the future market price of our ADSs and shares.

As of December 31, 2015, the total beneficial shareholding of our directors and executive officers (including shares held in a management trust) was approximately 67,234,136 or 11.0%, of our outstanding shares. This total included shares beneficially owned by the Chairman of our Board of Directors, Bernardo Quintana Isaac, or his family, including Alonso Quintana (our former Chief Executive Officer, and a member of our Board of Directors), Diego Quintana (formerly responsible for investments in our industrial construction operations and all partnerships, former member of our Board of Directors and current Chairman of GACN’s Board of Directors), and Rodrigo Quintana (our General Counsel), comprising approximately 7.4% of our outstanding shares. Additionally, the management trust held 21,631,035 or 3.5%, of our outstanding shares (including 1.1% shares included in the total of beneficial ownership by the Quintana family). Another trust controlled by our management, the foundation trust, held 8,343,608 or 1.4%, of our shares. See “Item 6. Directors and Senior Management—Share Ownership,” “—Compensation—Management Bonuses” and “Item 7. Major Shareholders and Related Party Transactions—Major Shareholders.”

Actions by our management and Board of Directors with respect to the disposition of the shares and ADSs they beneficially own, or the perception that such action may occur, may adversely affect the trading price of the shares on the Mexican Stock Exchange or the ADSs on the New York Stock Exchange.

Holders of ADSs and CPOs are not entitled to vote.

Holders of ADSs and the underlying CPOs are not entitled to vote the shares underlying such ADSs or CPOs. Such voting rights are exercisable only by the CPO trustee, which is required to vote all such shares in the same manner as the holders of a majority of the shares that are not held in the CPO trust and that are voted at the relevant meeting. As a result, holders of ADSs or CPOs will not be entitled to exercise minority rights to protect their interests and are affected by decisions taken by significant holders of our shares that may have interests different from those of holders of ADSs and CPOs.

Item 4. Information on the Company

A. HISTORY AND DEVELOPMENT OF THE COMPANY

We are a sociedad anonima bursatil de capital variable incorporated as Empresas ICA, S.A.B. de C.V. under the laws of Mexico. Our business began in 1947 with the incorporation of Ingenieros Civiles Asociados, S.A. de C.V., which provided construction services for infrastructure projects for the Mexican public sector. Our registered office is located at Blvd. Manuel Avila Camacho 36, Col. Lomas de Chapultepec, Del. Miguel Hidalgo, 11000 Mexico City, Mexico, telephone (52-55) 5272-9991.

We are an engineering, procurement and construction company, and a provider of construction services to both public and private-sector clients in Mexico and abroad. We are engaged in a full range of construction and related activities, involving the development and construction of infrastructure facilities, as well as industrial and urban construction. In addition, we are engaged in the construction, maintenance and operation of airports, highways, social infrastructure and tunnels and in the management and operation of water supply systems and solid waste disposal systems under concessions granted by governmental authorities.

Since 1947, we have expanded and diversified our construction and related businesses. In the past, our business strategy had been to strengthen and expand our core construction business, while diversifying our sources of revenue. We are active in every stage of the infrastructure development cycle, from engineering and financing to construction and operation. In 2016 we expect to focus on our construction activities in Mexico. Our construction business accounted for approximately 62% of revenues in 2015, 66% in 2014, 67% in 2013 and 80% in 2012.

We also expect to continue our planned asset sales. These planned asset sales may be of our entire interest in an asset or may involve sales of shares representing less than a controlling interest which would allow us to obtain value in the short term and retain control. This includes the securitization and subordination of our project debt and sale of minority stake in our assets.

Due to our current lack of liquidity, in December 2015 we suspended corporate debt payments and entered into a full operational and financial restructuring. As of December 31 2015, our restructuring was focused on cost reduction, including a reduction of our workforce. Our workforce of 22,116 total employees (of which 9,898 are administrative staff) as of December 31, 2015 represents a reduction of 9,188 total employees and 2,295 administrative staff employees, as compared to December 31, 2014. Our workforce of 18,069 total employees (of which 8,473 are administrative staff) as of April 30, 2016 represents a reduction of 14,647 total employees and 4,072 administrative staff employees as compared to April 30, 2014.

Capital Spending

Our capital spending program is focused on the acquisition, upgrading and replacement of property, plant and equipment as well as investments in infrastructure concessions required for our projects.

The following table sets forth our capital spending for each year in the three-year period ended December 31, 2015. Capital spending in the following table includes amounts invested for property, plant and equipment as well as for acquisitions of real estate inventories, which are included in the Corporate and Other segment. Acquisitions of real estate inventories are included in operating activities in our consolidated statements of cash flows. Accordingly, the table below does not reflect capital expenditures as reported in our consolidated statements of cash flows. Capital spending in our Industrial Construction segment is not reflected in our consolidated capital spending, but is incorporated in our consolidated results through our share in results of joint ventures and associated companies.

	Year Ended December 31,
	2015			2015			2014			2013
	(Millions of U.S. dollars)			(Millions of Mexican pesos)
Civil Construction	U.S.$	166			Ps. 2,877			Ps. 710			Ps. 487

Industrial Construction Eliminations		(5	)		(85	)		(52	)		—
Total	U.S.$	478			Ps. 8,283			Ps. 6,902			Ps. 8,113

Aggregate capital spending increased 20% in 2015 as compared to 2014. The increase in aggregate capital spending in 2015 primarily reflected increased spending in our Construction and Concession segments. The increased spending in our Construction segment was primarily due to investments in machinery and equipment. Concession segment was primarily due to investments in Barranca Larga-Ventanilla Highway, Palmillas – Apaseo el Gande toll road and Acapulco Scenic Bypass. In our Airports segment the increase in spending primarily resulted from increased spending on improvements related to teminals, runways and aprons. The decreases in the Corporate and Other segment primarily resulted from the decrease in our real state business .

Our principal capital expenditures currently in progress include Ps. 3,862 million in investments in our Concessions segment. Most of our principal expenditures are in Mexico and funded through third party financings, including proceeds from our 2011, 2012 and 2014 notes offerings and our 2009 equity offering. Third party financing, other than our 2011, 2012 and 2014 senior notes offerings and 2009 equity offering, is typically structured through project finance vehicles and, to a lesser extent, through corporate term loan financing.

In 2012, ICA acquired the business of San Martin. As of December 31, 2014, we had a pending consideration payment of US $46.4 million, equivalent to Ps.683.7 million, which was scheduled to be paid as follows: (i) a payment of US $ 33.8 million in June 2015 and (ii) another payment for US $12.6 million in May 2016, in addition to the agreement to pay interest. The payment due in June 2015 was not fully paid, resulting in the total pending consideration amount becoming immediately due and payable. However, we negotiated with the counterparty to make a partial payment and extend the date for payment of the remaining payment. On October 19, 2015, our Company received formal notification of default and on October 22, 2015, settlement of the obligation was made through delivery by our Company of 19.98% of its shareholding in San Martin, thereby reducing our investment to 31.2%. Our Company also assigned to another shareholder legal rights over dividends on future results of San Martín up to US $3 million and a new shareholder agreement was signed, where the relevant operating and financing decisions of San Martin and the board integration are in favor of another shareholder.

As a result of the above, in October 2015, ICA lost control over the management and operation in San Martín and ceased consolidating the entity as of such date.

26

On April 14, 2014, our subsidiary, ICATECH Corporation, acquired 100% of the equity of Facchina Construction Company, Inc. (“Facchina”), a U.S. medium-sized heavy construction firm that operates in the Washington D.C. metropolitan area and the southeast of Florida. The purchase price is payable over a five-year period and could range from our initial payment of U.S.$59.3 million to a total of U.S.$95 million if Facchina meets agreed EBITDA targets and other conditions established by us and Facchina. In 2015, we negotiated a U.S.$5.1 million reduction of initial payment amount , decreasing the intial payment to U.S.$54.2 million. As of December 31, 2015, the amount of contigent consideration is U.S.$18.4 million or Ps. 319.6 million. This acquisition is included in the Civil Construction segment

Divestitures

We have recently undertaken several divestments as part of a short-term strategy to reinvest capital in new projects and pay down certain indebtedness.

On September 3, 2015, we sold our shares of Grupo Punta Condesa, S. A. de C.V., a subsidiary of ViveICA, S. A. de C.V. The sale price was Ps. 500 million, of which Ps.150 million was collected on the date of signing the agreement, Ps. 150 million was collected within 90 calendar days following the date of the agreement and Ps. 200 million remains to be collected on July 3, 2016.

On December 17, 2015, our Company signed a sale and purchase agreement with CI Banco Institución de Banca Múltiple to sale its participation in Proactiva Medio Ambiente, S.A. de C.V. (“Proactiva”), representing 49% of the shares of Proactiva. The agreed price was Ps. 1,240 million, consisting of an initial payment of Ps. 992 million or 80% of the price, with the remaining Ps. 248 million, or 20% of the payment, deposited into a trust chosen by the buyer. Of this Ps. 248 million, 5% of the purchase price is allocated for possible indemnity payments to the buyer and 15% is allocated to payment of the remaining purchase price, subject to certain conditions being met and subject to adjustments under the contract.

In September 2015, our Company transferred its fiduciary rights in the real estate development Reserva Escondida, for Ps. 100 million.

In October 2015, our Company sold its 50% stake in Grupo Rodio Kronsa for an amount of Ps. 284 million.

On January 5, 2016, Aeroinvest merged into CONOISA, a wholly-owned subsidiary of EMICA, with CONOISA as the surviving entity. As a result of this internal merger, CONOISA assumed all of the rights and obligations of Aeroinvest, including with respect to Aeroinvest’s beneficial ownership of Series B Shares of GACN.

In January 2016, in connection with the termination of a financing transaction with Banco Santander Mexico S.A. (“Santander”), (i) on January 8, 2016, Santander sold an aggregate of 27,795,120 Series B Shares of GACN, or 6.9% of Series B Shares of GACN currently outstanding, at a price of Ps. 78.01 per Series B Share, which resulted in aggregate net proceeds of Ps. 2,168 million; and (ii) on January 15, 2016, Monex Casa de Bolsa, S.A. de C.V.,

See Note 42 to our consolidated financial statements.

In August 2013, we completed the sale of our 18.7% stake in Red de Carreteras de Occidente, S.A.B. de C.V., or RCO, the concessionaire for approximately 760 kilometers of highways in Mexico, to funds managed by Goldman Sachs for approximately Ps. 5,073 million. The gain on the sale in this investment was Ps. 441 million.

In the fourth quarter of 2013, we completed the sale of our Ciudad Acuña water treatment plant to Suministros Termoelectronicos, S.A. de C.V. and Promotora ELJA, S.A. de C.V. for a purchase price of approximately Ps. 145 million. We will no longer operate and maintain this water treatment plant.

In December 2013, we entered into an agreement with Promotora del Desarrollo de America Latina, S.A. de C.V., for the sale of our interest in the Atotonilco water treatment plant concession. In November 2014 we completed the sale of our interest in the Atotonilco water treatment plant concession for a purchase price of approximately Ps. 55 million.

In December 2013, we completed the sale of our interest in the Panamanian company Compania Insular Americana, S.A., a company created to perform the real estate development of previously existing fill-in rights from our prior Corredor Sur concession, to Ocean Reef Islands Inc. for a purchase price of Ps. 225 million.

On March 31, 2014, we completed the sale to Promotora del Desarrollo de America Latina, S.A. de C.V. of our interest in the concession for the Autovia Urbana Sur expressway for a purchase price of approximately Ps. 1,000 million. We will no longer operate and maintain this expressway. See Note 34 to our consolidated financial statements.

In January 2014, we announced that we had signed an agreement with CGL Management Group, LLC, or CGL, a subsidiary of the Hunt Corporation, to form a joint venture for managing and developing additional social infrastructure facilities in Mexico. Under the agreement, we would sell to CGL a 70% equity interest in the holding company of our two SPC contracts to provide future ongoing non-penitentiary services at the federal detention centers in Sonora and Guanajuato for a purchase price of approximately U.S.$ 116 million. As of December 31, 2013, the related assets and liabilities were classified as held for sale, valued at their fair value, in our consolidated statement of financial position. Their results of operations were classified as discontinued operations.

28

Subsequently, on December 5, 2014, we and CGL announced that we had terminated the agreement due to the parties’ failure to obtain consent from the Mexican federal government for the transaction as proposed. However, as we actively sought sale of our investment, we continued to report discontinued operations in our consolidated financial statements as of and for the year ended December 31, 2014.

During 2015, after not receiving a formal offer to purchase, the administration of our Company decided to withdraw its intention to sell such assets. Consequently, at December 31, 2015, we reclassified the operations of the two SPC contracts to continuing operations for all years presented.

On April 13, 2015, we announced that we had signed an agreement with the Caisse de dépôt et placement du Québec (CDPQ) to form an entity focused on developing, operating, and acquiring non-rail road, highway and toll-road infrastructure assets in Mexico. Under the agreement, we sold to CDPQ a 49% interest in our subsidiary ICA OVT, which owns the toll road and highway concessions of our concessionaire subsidiaries Consorcio del Mayab, S.A. de C.V., ICA San Luis, S.A. de C.V., Libramiento La Piedad, S.A. de C.V. and Túneles Concesionados de Acapulco, S.A. de C.V., including the concessions for the Mayab Toll Road, the Rio Verde-Ciudad Valles Highway, the La Piedad Bypass and the Acapulco Tunnel. We hold a 51% stake in ICA OVT after the closing of the transaction. We continue to operate the highways owned by ICA OVT and are responsible for all operating and maintenance and major maintenance requirements for those highway concessions. In June 2015, our Company completed the sale of 49% of our stake in ICA OVT to CDPQ, who paid approximately Ps. 3,014 million for the participation in ICA OVT’s capital. The financial statements of ICA OVT continue to be incorporated in the consolidated financial statements, since we exercise control over the entity.

Public Sector Spending and the Mexican Economy

Our performance and results of operations historically have been tied to Mexican public sector spending on infrastructure and industrial facilities. Mexican public sector spending, in turn, has generally been dependent on the state of the Mexican economy and accordingly has varied significantly in the past. Mexico’s gross domestic product grew by 5.5% in 2010. In 2012 GDP grew by 3.9%, and in 2013, GDP grew by 1.1%. In 2014, GDP grew by 2.1%. In 2015, GDP grew by 2.5%. The average interest rates on 28-day Mexican treasury notes were 3.14% in 2015, 3.0% in 2014 and 3.7% in 2013. Inflation was 2.13% in 2015, 4.1% in 2014 and 3.9% in 2013.

According to the INEGI, GDP of the Mexican construction sector, in real terms as compared to the prior year, increased by 2.5% in 2015, increased by 1.9% in 2014 and decreased by 4.7% in 2013, and represented 7.1%, 7.3%, and 7.4% of Mexico’s total gross domestic product in those years, respectively. According to data published by the Mexican Ministry of Finance and Public Credit, the average annual budgetary investment in infrastructure was 7.2% of GDP during 2013, and 5.5% during the period between 2008 and 2012.

In June 2013, Mexican President Enrique Peña Nieto announced the National Development Plan for the period 2013 to 2018. The new program contemplated investments of approximately U.S.$ 415 billion, representing 5.7% of Mexico’s gross domestic product, in over 1,000 projects in the transportation, water management, energy and urban development sectors. The majority of the budget (approximately 64%) was expected to be allocated to the energy sector, and investment in highways was expected to represent approximately U.S.$ 17 billion, or 4.1% of the proposed new program. The program was expected to generate 3.9 million jobs and to contribute to Mexico’s economic development.

In December 2013, the Mexican government enacted constitutional amendments designed to reform Mexico’s energy industry in order to allow greater economic development. These reforms are expected to stimulate public and private investment in Mexico’s energy industry, including infrastructure development. We believe that we are well positioned to take advantage of these developments and the expected economic growth given our experience in construction and construction-related services in the Mexican energy industry.

On April 29, 2014, Mexican President Enrique Peña Nieto announced the National Infrastructure Plan for the period 2014 – 2018. The new program contemplated investments of approximately Ps. 7,750 billion (U.S.$593 billion) in: (i) transportation and communication; (ii) energy; (iii) hydraulic development; (iv) health facilities; (v) urban development and housing; and (vi) tourism development, an increase over the 2013 announcements.

29

On January 30, 2015, the Mexican Ministry of Finance and Public Credit announced adjustments to the 2015 annual budget, reducing it by Ps. 124.3 billion, equivalent to 0.7% of Mexico’s GDP. The most affected government entities were PEMEX with a reduction of Ps. 62 billion and CFE with a reduction of Ps. 10 billion. The investment budget in infrastructure, was reduced by Ps. 18.1 billion, which included the cancellation of the Transpeninsular train and the suspension of the Mexico-Queretaro train. These adjustments are not expected to affect the project for the new international airport in Mexico City.

On March 20, 2015, at the closing of the 78th Mexican Banking Convention, Mexican President Enrique Peña Nieto announced that the 2016 budget would undergo a complete redesign. To that end he has instructed his Cabinet to analyze the budgets of various government agencies in order to find areas of opportunity.

On April 28, 2015, Banco de Mexico announced that they reported an operating surplus of Ps. 31,000 million in their audited financial statements for the year ended at December 31, 2014. As a result, its board decided, in compliance with the Banco de Mexico Law, to transfer this amount to the Mexican Federal Government.

On February 17, 2016 the Mexican Ministry of Finance and Public Credit announced adjustments to the 2016 annual budget, reducing it by Ps. 132.3 billion, or 0.7 of Mexico’s GDP. The entities most affected by this reduction in the annual budget were Pemex with a reduction of Ps. 100 billion and the Federal Government itself with a reduction of Ps. 32 billion. 40% of the Ps. 2016 annual budget reduction affects investment projects that have no immediate technical or legal feasibility. The 2016 annual budget protects projects such as the New Airport of Mexico City and the Train between Mexico and Toluca, which are a priority for the administration.

On April 4, 2016, a 175 billion budget cut was announced for the 2017 budget, affecting mainly the health, education and agriculture sectors. Among the priority programs of the government, a program of railway infrastructure of the SCT and three of the Comisión de Energía e Hidrocarburos will have reduced budgets for the year 2017.

B. BUSINESS OVERVIEW

For the years ended at December 31, 2015, 2014 and 2013, our results are presented with the following five business segments under IFRS:

• Civil Construction,

• Industrial Construction,

• Concessions,

• Airports, and

• Corporate and Other.

Historically, substantially all of our construction services were performed in connection with projects developed and financed by third parties. However, the current industry trend is that governments and government agencies, including the Mexican government and Mexican state-owned enterprises, have significantly changed their spending practices on traditional infrastructure and industrial facilities and have sought, instead, to stimulate private investment in such facilities. Accordingly, we are increasingly required to participate in arranging the financing for the construction of infrastructure facilities and to invest equity or provide other financing for such projects. Competition has also increased due in part to the ability of many foreign competitors to obtain financing on more attractive terms. We have experienced an increase in demand (and expect to continue experiencing strong demand) for infrastructure projects in which we are required to obtain financing, especially in projects for the construction of highways, railroads, power plants, hydroelectric projects, prisons, water storage facilities and oil drilling platforms and refineries.

Description of Business Segments

Construction

Our construction business in 2015 was divided into the Civil Construction and Industrial Construction segments. See “Item 4. Business Overview—Description of Business Segments—Construction—Civil Construction” and “—Industrial Construction.”

Contracting Practices

Historically, a majority of our construction business was conducted under unit price contracts, which contain an “escalation” clause that permits us to increase unit prices to reflect the impact of increases in the costs of labor, materials and certain other items due to inflation. Under this traditional form of contract, while a total price is quoted, the construction project is broken down into its various constituent elements, such as excavation volume, square footage of built-up area, footage of pipes to be laid, and a price per unit is established for each such element. Where the amount of work required to complete the contract (i.e., the amount of each constituent element) is greater than the amount quoted in the contract due to incorrect specifications or changes in specifications, we are entitled to an increase in the contract price on the basis of the quantity of each element actually performed, multiplied by its unit price. These unit price contracts allow flexibility in adjusting the contract price to reflect work actually performed and the effects of inflation.

In recent years, however, our construction contracts have been increasingly of the fixed price type or not to exceed type, which generally do not provide for adjustment of pricing except under certain circumstances for inflation or as a result of errors in the contract’s specifications, or mixed price contracts in which a portion of the contract is at fixed price and the rest at unit prices. Examples of mixed price projects in which we are currently involved include the Eastern Discharge Tunnel. Fixed price, not-to-exceed and mixed price contracts collectively accounted for approximately 46% of our Civil Construction backlog as of December 31, 2015, 58% of our Civil Construction backlog as of December 31, 2014 and 56% of our Civil Construction backlog as of December 31, 2013. Despite the decrease as a percentage of our backlog in 2015, we believe that fixed price contracts are more prevalent in the construction market and the contracts that we enter into in the future may reflect this shift to fixed price contracts. Additionally, we expect that, because of conditions attendant to financing arrangements, future concession-related, infrastructure and industrial construction contracts may restrict the adjustment of the contract price for additional work done due to incorrect contract specifications.

However, under Mexican law, traditional public works contracts provide for the price adjustment of certain components, regardless of whether the contract is fixed price or mixed price. Under a traditional public works mechanism, the counterparty pays us periodically (often monthly) as our work is certified over the term of the contract and we do not finance the project.

We earn a portion of our Civil Construction revenues under contracts whose prices are denominated in currencies other than Mexican pesos, substantially all of which are of the fixed price, mixed price or not-to-exceed type. Approximately 79% of our contract awards in 2015 (based on the contract amount) were foreign-currency denominated, including the Facchina’s contracts. Approximately 16% of our Civil Construction backlog as of December 31, 2015 was denominated in foreign currencies. Our foreign currency denominated contracts are denominated in U.S. dollars, Costa Rican colones, Peruvian Soles Colombian pesos and Guatemalan Quetzals.

Our policy requires that a committee review and approve all construction projects and concessions with construction components expected to generate material revenues. The committee supervises our decisions to bid on new construction projects based upon a number of criteria, including the availability of multilateral financing for potential projects, the availability of rights of way, the adequacy of project specifications, the customer’s financial condition and the political stability of the host country, if the project is outside of Mexico.

We obtain new contracts for new projects either through a process of competitive bidding or through negotiation. Generally, the Mexican Federal Public Administration and its agencies may only award construction contracts through a public bidding process conducted in accordance with the Public Works and Related Services

31

Law (Ley de Obras Publicas y Servicios Relacionados con las Mismas). However, public sector construction contracts may be awarded without a public bidding process under limited circumstances, such as: (i) in response to certain emergencies, including those relating to public health and safety as well as environmental disasters; (ii) when the project to be executed will be performed exclusively for military purposes or if the bidding process could jeopardize national security; (iii) when a publicly-bid contract has been rescinded due to breach by the winning contractor; (iv) when a public bidding process is declared void due to a lack of offers that comply with the bidding guidelines or prices or inputs are unacceptable, provided that the conditions of contracting are the same as those originally published; or (v) when there is a proven strategic alliance between the government and the contractor in order to promote technological innovation in projects. The majority of the contracts for new projects awarded to us from Mexican public-sector clients are awarded through competitive bidding. Most contracts for new projects awarded to us by private sector and foreign government clients are also the result of a bidding process.

The competitive bidding process poses two basic risks: we may bid too high and lose the bid or bid too low and adversely affect our gross margins. The volume of work generally available in the market at the time of the bid, the size of our backlog at that time, the number and financial strength of potential bidders, whether the project requires the contractor to contribute equity or extend financing to the project, the availability of equipment and the complexity of the project under bid are all factors that may affect the competitiveness of a particular bidding process. Direct negotiation (as opposed to competitive bidding) generally tends to represent a more certain method of obtaining contracts and to result in better gross margins.

In addition to construction contracts for new projects, increases in the scope of work to be performed in connection with existing projects are an important source of revenue for us. In 2015, increases in scope of work accounted for Ps. 8,734 million in our total construction backlog. Construction contracts for such work are not typically put up for bid, but are negotiated by the client with the existing contractor.

In determining whether to bid for a project, we take into account (apart from the cost, including the cost of financing, and potential profit) efficient usage of machinery, the relative ease or difficulty of obtaining financing, geographic location, project-specific risks, current and projected backlog of work to be performed, our particular areas of expertise and our relationship with the client.

As is customary in the construction business, from time to time we employ sub-contractors for particular projects, such as specialists in electrical, hydraulic and electromechanical installations. We are not dependent upon any particular sub-contractor or group of sub-contractors.

Backlog

Backlog in the engineering and construction industry is a measure of the amount of revenue that we expect to realize from future work under long-term contracts at a particular reporting period. These estimates include revenues that we reasonably expect to realize from contracted work not yet completed at the beginning of the period, new contracts, firm orders, work scope modifications authorized by our clients, change orders authorized by our clients under conditions specified in the original contract and certain documented claims and termination or redemption fees presented to our clients. Backlog does not reflect operating margins earned from contract completion.

Backlog for each reporting period is calculated based on backlog from the prior reporting period, to which we (i) add estimated revenue from future uncompleted contracts, firm orders and other expected income streams and (ii) deduct revenue from contracts that have been canceled or fully completed during the reporting period. For each reporting period, we determine on a contract-by-contract basis as of the date of determination, the fair value of consideration billed or to be billed representing goods delivered and services to be delivered or performed over the course of the contract. Pursuant to the “percentage of completion” methodology, the contract amount for these purposes is estimated based on costs to be incurred through the end of the project and the estimated profit margin therein in accordance with IAS 11 “Construction Contracts.” Actual revenues earned from the contract during the reporting period are also determined based on the percentage-of-completion method. See Note 4(cc) to our consolidated financial statements.

32

Consolidated backlog includes contracts pursuant to which we control a project, such as when we hold a controlling interest, a leadership role and decision-making power regarding key project areas. Through September 2015, we consolidated the backlog of San Martin, both its civil construction backlog and its mining services backlog but commencing in October 2015, we deconsolidated both revenue and backlog. See Note 2 c to our consolidated financial statements. For internal reporting purposes, we group our mining services business within our Civil Construction segment due to the similarity between our mining services and certain services provided by our traditional construction business, which leads us to review and manage our mining activities within the scope of our Civil Construction segment’s performance metrics.

The following table sets forth, at the dates indicated, our backlog of Civil Construction, mining services and other services contracts. See Note 8 to our consolidated financial statements.

Total Civil Construction contract awards and net additions to existing contracts totaled Ps. 13,624 million (approximately U.S.$786 million) in 2015. Ten projects represented approximately 75% of backlog in the Civil Construction segment, and 86% of total consolidated backlog, each at December 31, 2015. The following table sets forth certain information relating to these ten projects:

	Amount		Estimated Completion Date		% of Total Civil Construction Backlog
	(Millions of Mexican pesos)

33

As of December 31, 2015, approximately 16% of Civil Construction backlog was attributable to construction projects outside of Mexico. Public sector projects represented approximately 81% of our total Civil Construction backlog. At December 31, 2015, construction contracts with a value exceeding U.S.$200 million accounted for 38% of our total Civil Construction backlog, construction contracts with a value ranging from U.S.$100 million to U.S.$200 million accounted for 40% of our Civil Construction backlog and construction contracts with a value of less than U.S.$100 million accounted for 21% of our total Civil Construction backlog. Of these ten projects, the Mitla-Tehuantepec Highway had changes to margins, which decreased by 1.2% in 2015 compared to 2014, Facchina’s Projects decreased in 2.9%, the Palmillas – Apaseo El Grande Highway decreased by 1.1%, Tunel Emisor Oriente decreased by 2.4%, Churubusco Xochiaca Tunnel decreased by 0.3% and the Sonora Package Highways in Sonora State decreased by 0.9% .

In the case of joint ventures in which we share control, as well as associated companies, we include in unconsolidated backlog a share of expected contract revenues that corresponds to our percentage interest in the joint venture or associated company.

The following table sets forth, at the dates indicated, our unconsolidated backlog of joint venture and associated company contracts.

	As of December 31,
	2015		2015		2014		2013
	(Millions of U.S. dollars)		(Millions of Mexican pesos)
Joint Venture and Associated Company Backlog	U.S. $	1,855		Ps. 32,163		Ps. 43,921		Ps. 10,864

In 2015, Civil Construction backlog included the maintenance of approximately 990 kilometers of oil pipelines in southern Colombia for Ps. 1,937 million, the construction of the Acapulco Scenic Bypass in Acapulco Guerrero for Ps. 1,051 million and Facchina’s joint ventures for Ps. 464 million. We also incorporated backlog from San Martin’s joint ventures of Ps. 5,938 million.

Joint venture and associated company backlog increased 51% from 2015 over 2014 principally due to the incorporation of San Martin’s backlog related to mining and construction, which as of December 31, 2015 were Ps. 5,938 million, and the incorporation of a Ps. 17,616 million agreement related to ICA Fluor on the Tula 4a Package, Joint venture and associated company backlog increased 95% from 2014 over 2013 principally due to new contracts of ICA Fluor (of which we own a 51% share), including Ps. 18,339 million from the Tula Refinery Phase II, Ps. 9,379 million from the Ramones II Sur Gas Pipeline and Ps. 3,549 million from the well pad modules for Shell Canada, as well as net contract additions. See “Item 4. Information on our Company—Business Overview—Description of Business Segments—Construction—Civil and Industrial Construction”.

The amount of backlog is not necessarily indicative of our future revenues related to the performance of such work. Although backlog represents only business that is considered to be firm, we cannot assure you that cancellations or scope adjustments will not occur. In 2015, cancellations and scope adjustments did occur with respect to the TEC II and Monterrey VI contracts. However, margin trends are primarily influenced by the mix of projects in backlog, competition on awarded contracts, overall industry trends, force majeure, and delay in delivery of or obtaining rights-of-way, change orders and alleged breaches of contract, many of which are difficult to predict. In the period leading up to and following the change in presidential administration, the number of large public sector construction contracts the Mexican government offered for public bidding decreased. We experienced a significant decrease in the rate of awards in 2013 due to the change of administration as well as the administration’s initial focus on structural reforms, rather than a focus on its infrastructure projects. We have continued to experience a slowdown in contract awards through the first quarter of 2016. We can make no assurances that the rate of awards will increase.

34

In certain instances, we have guaranteed completion by a scheduled acceptance date or achievement of certain acceptance and performance testing levels. Failure to meet any such schedule or performance requirements could result in costs that exceed projected profit margins, including substantial penalties fixed as a percentage of a contract price. Fixed price, not-to-exceed and mixed price contracts collectively accounted for approximately 46% of our Civil Construction backlog as of December 31, 2015. See “Item 5. Operating and Financial Review and Prospects—Operating Results—Backlog.”

Competition

The main competitive factors in our Civil Construction segment, in addition to price, are performance and the ability to provide the engineering, planning, financing and management skills necessary to complete a project in a timely fashion.

The market for construction services in Mexico and elsewhere is highly competitive. In the Civil Construction segment, competition is relatively more intense for infrastructure and industrial construction projects outside Mexico.

In our Civil Construction segment, in addition to the Mexican companies, we compete primarily with Spanish and Brazilian companies. Major competitors include IDEAL and Carso Infraestructura y Construcciones, S.A. de C.V., both related parties of Grupo Carso, Omega Construcciones Industriales, S.A. de C.V., GIA+A, S.A. de C.V., Tradeco Infraestructura, S.A. de C.V., La Peninsular Compañia Constructora S.A. de C.V. (a member of Grupo Hermes), COCONAL, S.A. de C.V., Promotora y Desarrolladora Mexicana, S.A. de C.V., Azvi-Cointer de Mexico, S.A. de C.V., Fomento de Construcciones y Contratas, S.A., or FCC, ACS Actividades de Construcciones y Servicios, S.A. and Dragados S.A. (together, ACS), Mota-Engil, S.A. de C.V., and Constructora Aldesem, S.A. de C.V. This market is fragmented, with many small local participants in civil construction. In our Concessions segment, we compete primarily with Mexican and Spanish companies, including IDEAL, Globalvia Infraestructuras, S.A. de C.V., Compañia Contratistas Nacional, S.A. de C.V., La Peninsular Compañia Constructora, S.A. de C.V., OHL Mexico, S.A.B. de C.V., Promotora y Operadora de Infraestructura, S.A.B. de C.V., Fomento de Construcciones y Contratas, S.A., FCC Aqualia, S.A., Acciona Agua, S.A., Abengoa Mexico, S.A. de C.V., Impulsa Infraestructura, S.A. de C.V., Mota-Engil, S.A. de C.V., Mitusui de México, S. de R.L. de C.V., Grupo México, S.A.B de C.V. and GIA, S.A. de C.V.

We believe that our proven track record in Mexico and our experience and know-how have historically allowed us to maintain our leadership position in the Mexican construction market. Nevertheless, our recent limited liquidity has decreased our ability to compete in both the Concessions and Civil Construction segments. In recent years, the sponsors of many infrastructure construction and industrial construction projects throughout the world, including Mexico, have required contractors to provide construction on a “turnkey” basis. Many of our foreign competitors have better access to capital and greater financial and other resources. As a result, we have been increasingly experiencing significant competition in Mexico from Brazilian, Chinese, Japanese, Spanish and, to a lesser extent, other European construction companies.

Raw Materials

The main raw materials we require for our construction operations are cement, construction aggregates and steel. In our Civil Construction segment, raw materials accounted for Ps. 4,702 million, or 13%, of our consolidated cost of sales in 2015, Ps. 5,861 million, or 19%, of our consolidated cost of sales in 2014 and Ps. 3,806 million, or 16%, of our consolidated cost of sales in 2013.

Civil Construction

Our civil construction business focuses on infrastructure projects in Mexico, including the construction of roads, highways, transportation facilities (such as mass transit systems), bridges, dams, ports, hydroelectric plants, prisons, tunnels, canals and airports, hospitals, athletic complexes as well as the construction, development and remodeling of large multi-storied urban buildings, including office buildings, multiple-dwelling housing developments shopping centers. Our Civil Construction segment has also pursued projects in other parts of Latin America such as: Panama, Colombia, Guatemala, Costa Rica, Chile, Peru (through San Martín a consolidated

35

subsidiary through September 2015, subsequently accounted for as an equity method investment), as well as in the United States (through Facchina). Our civil construction business performs activities such as demolition, clearing, excavation, de-watering, drainage, embankment fill, structural concrete construction, concrete and asphalt paving, mining services and tunneling.

In addition to construction for third parties, our civil construction business also includes revenues earned by our construction subsidiaries for construction work on our concessions performed under Engineering, Procurement and Construction (“EPC”) contracts with our concessionaire subsidiaries. These are eliminated upon consolidation but are presented within the civil construction business’ individual financial information.

In 2015, our Civil Construction segment accounted for approximately 62% of our total revenues.

The civil construction business projects are usually large and complex and require the use of large construction equipment and sophisticated managerial and engineering techniques. Although our Civil Construction segment is engaged in a wide variety of projects, our projects generally involve contracts whose terms range from two to five years.

We have played an active role in the development of Mexico’s infrastructure and have completed large infrastructure facilities and constructed buildings throughout Mexico and Latin America. Among the facilities and buildings we have constructed from our incorporation in 1947 through 2015:

• the Apulco, Comedero, El Novillo, El Caracol, Cajon de Peña, Tomatlan, Infiernillo, Chicoasen, El Guineo, El Cobano, Jicalan, Falcon, Huites, Aguamilpa, Caruachi, El Cajon and La Yesca power dams;

• the Mazatlan-Culiacan, Leon-Lagos-Aguascalientes, Guadalajara-Tepic, Mexico City-Morelia-Guadalajara, Cuernavaca-Acapulco, Oaxaca-Sola de Vega, Libramiento La Piedad, Río de los Remedios Ecatepec, Rioverde-Ciudad Valles and, Nuevo Necaxa-Tihuatlán concessioned highways and the Tehuacan-Oaxa federal highways as well as the Panama South Corridor;

• 17 of the 58 existing airports in Mexico and two airports outside Mexico (the Tocumen Panama international airport in Panama and the Philip S.W. Goldson international airport in Belize) and Terminal 2 of the Mexico City International Airport;

• Buildings, including: offices, hospitals, stadiums, hotels such as Torre Mayor, Internacional Convention Center in Los Cabos, Manuel Gea González Hospital, Chivas Soccer Stadium, Hyatt Regency (formerly Hotel Nikko), Paraíso Radisson in Mexico City represent just some of our important buildings.

• Lines 1through 12, A and part of B of the Mexico City metro system; and

• deep sewage systems, such as Río de la Compañía Tunnel, Medellín Northern Interceptor and Tunnel Emisor Oriente.

The following projects under construction contributed the most to revenues in the Civil Construction segment during 2015:

• Mitla – Tehuantepec Highway;

• Monterrey VI Aqueduct ⁽¹⁾;

• Churubusco Xochiaca Water Tunnel;

• Facchina projects (including Le Parc, Apollo Residences at Town Center, the Grove at Grand Bay, Crimson Tower and Hoffman Town Center);

36

• San Martin projects (including Minera Chinalco Peru S.A., Hudbay Peru SAC, Union Andina de Cementos S.A.A. – UNACEM S.A.A., Gold Fields La Cima S.A.A. Shougang Hierro Peru S.A.A, and Compañía Minera Coimolache, S.A.);

• Palmillas-Apaseo El Grande Toll Road;

• Lazaro Cardenas Port Terminal;

• Corredor Norte Toll Road in Panama;

• Barranca Larga – Ventanilla Highway; ⁽¹⁾

• Eastern Discharge Tunnel;

• Mexico-Toluca Railway Tunnel; and

• Santa Maria Dam.

(1) These projects have recently been suspended; see further discussion below.

The civil construction business’ contract awards and additions in 2015 totaled approximately Ps. 13,624 million (approximately U.S.$786 million), of which Ps. 9,699 million were awarded outside Mexico, including the Facchina contracts.

The following projects were key projects in the Civil Construction segment, due to their contributions of revenues or backlog to the segment in 2015:

Mitla-Tehuantepec Highway. In June 2010, through our wholly-owned subsidiaries, Caminos y Carreteras del Mayab, S.A.P.I. de C.V. and CONOISA, we entered into a 20-year PPP concession for the construction, operation and maintenance of the 169-kilometer Mitla-Tehuantepec federal highway, which is expected to link the city of Oaxaca with the Isthmus of Tehuantepec, Mexico, thereby increasing connectivity between the industrial port of Salina Cruz and Oaxaca. The construction contract has a value of approximately Ps. 9,456 million. Construction of the highway, which includes three segments—Mitla-Santa María Albarradas, Santa Maria Albarradas-Lachiguir and Lachiguiri-Entronque Tehuantepec II. In January 2012, we completed the transfer of a 40% interest in this concession to IDEAL and now hold a 60% interest. In 2013, we entered into an agreement with IDEAL in this project, whereby we gained control of the construction contract. The highway is expected to be completed in November 2017. A rescheduling of the term of the construction works is currently under negotiation between the concessionaire and the Communications and Transportation Ministry, (“the SCT”), as a result of delays in the project caused by certain political and social issues and delays in the delivery of rights of way outside our Company’s control.

Monterrey VI Aqueduct. On October 6, 2014, a consortium led by our subsidiary CONOISA signed one of the first contracts under the new Public Private Partnership law in Mexico with the Water and Drainage Services of Monterrey (Servicios de Agua y Drenaje de Monterrey), the water and sanitation services company of the State of Nuevo León. CONOISA has a 37.75% interest in the consortium. As of the date of this report the project is expected to be approximately Ps. 17,684 million. The Monterrey VI Aqueduct will bring water from intake works on the Rio Panuco to the existing Cerro Prieto reservoir in Linares, Nuevo León and pass through the states of San Luis Potosi, Veracruz, and Tamaulipas. The 84-inch diameter pipeline will have a maximum capacity of 6,000 liters/second. The project also includes six pumping stations, seven regime change tanks, a regulation tank, a pre-treatment system, and telemetry. The project has been suspended by the Water and Drainage Services of Monterrey and the consortium hasn’t received any further communication from the client.

Palmillas-Apaseo El Grande Toll Road. We were awarded a 30-year concession for the Palmillas-Apaseo El Grande Toll Road by the Ministry of Communications and Transportation in November 2012. The concession title was signed in February 2013 for a total investment of Ps. 9,359 million. In June 2013 we entered into a Ps. 5,675

37

million loan agreement, which was modified on September 19, 2013 to Ps. 5,450 million. The 86-kilometer, 4-lane, high specification toll road in the states of Queretaro and Guanajuato will create a new link between the Mexico City metropolitan region, the Central Mexican region and the Northern Mexican region. The concession includes nine interchanges, 29 vehicular overpasses and underpasses and calls for the construction of 15 major bridges, and is expected to start operations in 2016.

Churubusco Xochiaca Water Tunnel. On August 19, 2014, we were awarded a contract by the National Water Commission to build the Churubusco-Xochiaca water tunnel in Mexico City and Mexico state with a total value of Ps. 2,566 million. The fixed-price contract was awarded through a domestic bidding process. Construction will be completed over a period of 29 months. The Churubusco-Xochiaca water tunnel is designed as an additional measure to reduce seasonal flooding in the Valley of Mexico, particularly in a portion of the Nezahualcoyotl municipality and the adjacent Venustiano Carranza district of Mexico City. The project includes construction of a 13 kilometer, 5 meter interior diameter tunnel, nine 12-meter diameter drop shafts with a depth of 30 meters, six 8-meter diameter drop shafts with a depth of 18 meters, and associated work.

Barranca Larga – Ventanilla—Highway. In August 2012, our construction company Ingenieros Civiles Asociados, S.A. de C.V. was awarded a contract to perform the construction work under the Barranca Larga – Ventanilla concession. This concession was awarded on April 16, 2012, by the Ministry of Communications and Transportation to our concession subsidiary Desarrolladora de Infraestructura Puerto Escondido, S.A. de C.V., or DIPESA. It is a 30-year concession for the construction, operation and maintenance of the 104-kilometer Barranca Larga-Ventanilla toll road in the state of Oaxaca. Constructions cost overruns caused by social and environmental issues and updated traffic studies have shown that the project is no longer financially viable. Accordingly, ICA has suspended construction work on most of the project. ICA is currently analyzing alternatives to restore the project to financial viability. An allowance of Ps. 1,731 million was recorded related to receivables from cost overruns; additionally, an impairment of Ps. 2,209 million in the intangible asset was recorded in 2015. See Note 13(h) to our consolidated financial statements.

Eastern Discharge Tunnel. In November 2008, the Mexican National Water Commission (Comisión Nacional del Agua), the government of Mexico City and the government of the state of Mexico, acting together as a trust, awarded an ICA-led consortium a Ps. 9,595 million (excluding value-added tax) contract for the construction of the Eastern Discharge Tunnel (Tunel Emisor Oriente) in the Mexico City valley. The tunnel will increase drainage capacity in the Mexico City region and prevent flooding during the rainy season. The ICA-led consortium, Constructora Mexicana de Infraestructura Subterranea, S.A. de C.V., is comprised of Ingenieros Civiles Asociados, S.A. de C.V., Carso Infraestructura y Construccion, S.A. de C.V., Construcciones y Trituraciones, S.A. de C.V., Constructora Estrella, S.A. de C.V. and Lombardo Construcciones, S.A. de C.V. We recognize 50% of the operations from this project, or Ps. 4,797 million of the total construction contract. In 2011, we entered into an agreement increasing our share of the total contract value to Ps. 7,062 million. In 2012 and 2013 we received an additional contract increase of Ps. 230 million, for a total value of Ps. 7,292 million. In 2014 we received an additional contract increase of Ps. 2,023 million, for a total value of Ps. 9,315 million. In 2015 we received an additional contract increase of Ps. 769 million, for a total value of Ps. 10,084 million. The fixed-term contract has both unit price and fixed price components, and scheduled completion of the project in October 2018. The construction contract is under a traditional public works mechanism, in which the counterparty pays us periodically (often monthly) as our work is certified over the term of the contract and we do not finance the project. The project includes the construction of a 62-kilometer tunnel and 24 related access shafts. The tunnel will start at the border of the Federal District and Ecatepec, run along one side of Lake Zumpango, and end in El Salto, Hidalgo.

Mexico – Toluca Railway Tunnel. In August 2014, we were awarded, through a consortium, a construction contract for Ps. 10,400 million, of which we recognize a backlog for Ps. 2,462 million. This contract was awarded by the by the Secretariat of Works and Services of Mexico City. The project consists of a high speed rail (160 kilometers per hour) along the 57.7 kilometer route between the Observatorio metro station in Mexico City and Zinacatepec in the State of Mexico. The second phase includes the construction of two 4.6-kilometer tunnels. This project is scheduled to take 25 months.

Santa Maria Dam. In November 2014, we were awarded a Ps. 3,989 million unit-price public-works contract by the National Water Commission and the Environmental and Natural Resources Commission for the construction of Santa Maria water storage dam, located over the Baluarte River, in the region of Rosario in Sinaloa. This public works contract has a 3-year maturity. The construction schedule is currently under negotiation with the

38

client as a result of delays caused by a suspension order by the client. The contract scope includes river diversion works formed by two cofferdams, three 2.4 kilometer-length and 16x16 meter width portal-section tunnels with three intakes and six floodgates. The construction contract also includes containment structured works including a 153 meter concrete-based rock-fill with a 980 meters-cubed storage capacity.

Our Civil Construction segment has pursued infrastructure projects in Central, America, South America and the Caribbean Due to the current operational restructuring, we do not expect to seek future projects abroad in the near future except for those associated with Facchina. In the past, projects in these areas have ranged from construction of a section of the subway system in Santiago, Chile to the construction of a natural gas pipeline system in Argentina and the Caruachi hydroelectric dam in Venezuela. In 2015, 30% of our revenues in the Civil Construction segment were attributable to construction activities outside Mexico. In January 2010, a consortium comprised of ICA, with a 43% interest; Fomento de Construcciones y Contratas of Spain, with a 43% interest; and Constructora Meco of Costa Rica, with a 14% interest, was awarded a contract with an approximate value of U.S.$ 268 million by the Panama Canal Authority for the construction of a three-kilometer section of the new Pacific Access Channel (PAC-4) for the Panama Canal’s new Pacific locks, running parallel to the existing channel from the Pedro Miguel to the Miraflores locks. The unit price, fixed term public works contract was awarded through an international bidding process. The PAC-4 contract is part of the overall project to widen the Panama Canal. In 2011, we were awarded contracts to (i) build the Northern Interceptor Tunnel in Medellin, Colombia, (ii) extend the Avenida Domingo Diaz and the Corredor Norte highways, both in Panama City, Panama, and (iii) expand the Atlantic petroleum terminal in Limon, Costa Rica. In 2013, Ecopetrol, S.A. awarded a multi-year contract with an approximate value of U.S.$ 272 million to the Pipeline Maintenance Alliance, a consortium of which we hold a 30% interest, for the maintenance of approximately 990 kilometers of oil pipelines in southern Colombia. Work on the pipelines began in December 2013. In November 2012, the San Carlos Consortium, comprised of ICA, with a 70% interest; ALCA Ingenieria S.A.S., with a 15% interest; and NOARCO, S.A., with a 15% interest, was awarded a construction project with an approximate value of U.S.$ 40 million for the maintenance and rehabilitation of the Florencia Altamira Highway in Colombia. Due to our acquisition of the Facchina in April 2014, we acquired their contracts, which have an approximate construction backlog value of U.S.$208 million as of December 31, 2015.

Mining Services and Other Services

Additionally, in our Civil Construction segment we reported our mining services and other services contracts. As of December 31, 2015, we no longer report mining services backlog. As of December 31, 2015, the other services backlog was Ps. 91 million. This sub-segment in our backlog no longer contemplates mining contracts from San Martin its deconsolidation in October 2015. Until 2014, these projects principally reflected the contracts held by our San Martin subsidiary in Peru. As a result of our inability to pay the full amount of the remaining acquisition price of San Martin, we reduced our participation in San Martín from 51% to 31.2% during the last quarter of 2015, which led to a reduction in mining and other services backlog as of December 31 2015 compared to as of December 31 2014. The results of our participation in San Martin, via the equity method, continue to be accounted for in our Civil Construction segment.

Industrial Construction

Beginning in the fourth quarter of 2014, our executive committee began to include the stand alone internal financial data and operational performance of ICA Fluor in its regular review process due to the importance of ICA Fluor’s operations to our consolidated results, among other factors. Accordingly, we include our 50% interest in ICA Fluor as a separate Industrial Construction segment. The amounts attributable to ICA Fluor are removed from our consolidated segment information through Industrial Construction eliminations such that the operations of our Industrial Construction segment are reflected in our consolidated results through our share in results of joint ventures and associated companies. We include backlog for our Industrial Construction segment within joint venture and associated company backlog.

Industrial Construction projects focus on the engineering, procurement, construction, design and commissioning of large manufacturing facilities such as power plants, chemical plants, petrochemical plants, fertilizer plants, pharmaceutical plants, steel mills, paper mills, drilling platforms and automobile and cement factories.

Relationship with ICA Fluor. In 1993, we sold a 49% interest in our industrial construction subsidiary to Fluor Daniel Mexico, S.A., or Fluor, a subsidiary of The Fluor Corporation, forming the ICA Fluor joint venture. Since 1993, we have owned 50% of the ICA Fluor joint venture. Partner resolutions require the approval of a simple majority of ICA Fluor’s partners’ interests, except for decisions relating to matters such as capital increases, changes to ICA Fluor’s bylaws, dividend payments and a sale of all or substantially all of the assets of ICA Fluor. We and Fluor are each entitled to appoint an equal number of members of ICA Fluor’s board of directors and executive committee. Historically, we have designated the chief executive officer of ICA Fluor. In addition, we and Fluor have agreed that ICA Fluor will be the exclusive means for either party to provide construction, procurement, project management, start-up and maintenance services to the production and pipeline, power plant, petrochemical, industrial, environmental services, mining, chemicals and plastics and processing plants within Mexico, and portions of Central America and the Caribbean. This agreement will terminate upon a sale by Fluor or us of any of our partnership interests in ICA Fluor or, following a breach of any of the ICA Fluor agreements, one year after payment of any damages due to the non-breaching party in respect of this breach.

Typical Projects. Projects in our Industrial Construction segment typically involve sophisticated engineering techniques and require us to fulfill complicated technical and quality specifications. Our industrial construction backlog, as of December 31, 2015, was 43% peso-denominated and 57% dollar-denominated. 5% was fixed price and 95% was mixed price.

The most important projects under construction in our Industrial Construction segment during 2015 included:

• Tula 4a package, Integration and auxiliary Services.

It is the second package to be converted to the EPC stage under the open book established in the Phase I contract. The mechanical completion of the project is scheduled for the fourth quarter of 2017. ICA Fluor was awarded the contract for Phase I of the Residue Recovery Project for the Miguel Hidalgo refinery in 2013.

Concessions

Our Concessions segment focuses on the construction, development, maintenance and operation of long-term concessions of toll roads, tunnels, social infrastructure and water projects and accounted for 22% of our total revenues in 2015. The construction work we perform on our concessions is included in our Civil Construction segment when, pursuant to an EPC contract, we sub-contract one of our construction subsidiaries to perform the work. If the construction work is contracted with a third party, as is the case of construction of rights of way and environmentally-related construction such as environmental impact assessment, our construction subsidiaries do not perform any construction services. In these cases, the construction revenues are recognized within the Concessions segment rather than the Civil Construction segment. Our concessionaire subsidiaries also recognize financing income, which stems from the (i) reimbursement of the cost of financing obtained to build infrastructure assets granted under concession arrangements and (ii) interest income earned on concession assets accounted for as long-term accounts receivable.

We participate in all stages of infrastructure project development, including formulation, engineering, structuring and financing, construction, operation and management as part of a portfolio of assets. We monetize assets that are in the operating stage and arrange new projects under development.

During 2015, we participated in: (i) six concessioned highways operating, in whole or in part, and one operating concessioned tunnel (the Acapulco tunnel), five of which we consolidate, (ii) four highways in construction, three of which we consolidate, (iii) two operating prisons that we consolidate and (iv) the management and operation of water supply systems such as the Aqueduct II water supply system, the El Realito Aqueduct and the Agua Prieta Water Treatment plant, which we do not consolidate.

Contracting Practices

Mexican state and municipal governments and the governments of certain foreign countries award concessions for the construction, maintenance and operation of infrastructure facilities. The Mexican government actively pursues a policy of granting concessions to private parties for the design, construction, financing, maintenance and operation of highways, prisons, bridges and tunnels to promote the development of Mexico’s infrastructure without burdening the public sector’s resources and to stimulate private-sector investment in the Mexican economy. A long-term concession is a license of specified duration (typically between 20 and 40 years), granted by a federal, state or municipal government to finance, build, establish, operate and maintain a public means of communication or transportation.

Our return on any investment in a concession is based on the duration of the concession, in addition to the amount of toll revenues collected or government payments based on operation volume, operation and maintenance costs, debt service costs and other factors. Recovery of our investment in highway concessions is typically accomplished through the collection of toll tariffs or, if under the PPP contract structure, a fixed payment for highway availability (together with a smaller shadow tariff based on traffic volume), or a combination of the two methods. Our return on investment in our water treatment concessions is generally based on the volume of water supplied or treated.

To finance the obligations of our projects, we typically provide a portion of the equity and the rest is arranged through third party financing in the form of loans and debt securities. Recourse on the indebtedness is typically limited to the subsidiary engaged in the project. Our investment of equity is returned over time once the project is completed. Generally, we contribute equity to a project by accepting deferred payment of a portion of its construction contract price or through direct capital contributions. Depending on the requirements of each specific infrastructure concession project, we typically seek to form a consortium with entities that have expertise in different areas and that can assist us in obtaining financing from various sources.

Highway and Tunnel Concessions

The following table sets forth certain information as of December 31, 2015, regarding the eight highway and two tunnels concessions in which we currently participate, either through subsidiaries unconsolidated joint ventures or associated companies. As of December 31, 2015, we had five highway and one tunnel concessions in operation.

The Kantunil-Cancun Highway (Mayab Consortium). On March 12, 2008, we acquired all of the equity of the Mayab Consortium, which holds the concession for the Kantunil-Cancun toll road. We paid Ps. 912 million to acquire the Mayab Consortium, which holds the concession to construct, operate, and maintain the 241.5-kilometer highway that connects the cities of Kantunil and Cancun in the states of Yucatan and Quintana Roo through December 2020. In August 2011, we signed an amendment to our concession agreement with the Ministry of Communications and Transportation to construct an extension of the toll road. The amendment includes the construction, operation, conservation and maintenance of a 54-kilometer expansion of the Kantunil-Cancun highway to Playa del Carmen and extends the term of the concession to 2050. The expansion of the highway required an estimated investment of approximately Ps. 5,370 million. We consolidate the investment in our consolidated financial statements, including long term debt that, as of December 31, 2015, was equivalent to Ps. 4,542 million. This long-term debt matures in 2034, and is expected to be repaid from toll revenues generated by the concession. See “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Indebtedness—The Kantunil-Cancun Highway (Mayab Consortium).” On June 18, 2015, we announced that we had closed an agreement to sell to CDPQ a 49% participation in our subsidiary ICA OVT, which was established on March 19, 2015 and owns the Kantunil-Cancun Highway concession. We expect to continue to operate this highway for the 35 years remaining in the concession.

Acapulco Tunnel. In 1994, the government of the state of Guerrero granted our subsidiary Tuneles Concesionados de Acapulco, S.A. de C.V., or TUCA, a 25-year concession for the construction, operation and maintenance of a 2.9-kilometer tunnel connecting Acapulco and Las Cruces. The concession term started in June 1994. On November 25, 2002, the Congress of the State Government of Guerrero approved the extension of the concession term by 15 years because the actual volume of usage was lower than the amount foreseen by the terms of the concession agreement. See “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Indebtedness—Acapulco Tunnel” and Note 13 to our audited consolidated financial statements. On June 18, 2015, we announced that we had closed an agreement to sell to CDPQ a 49% participation in our subsidiary ICA OVT, which was established on March 19, 2015 and owns the Acapulco Tunnel concession. We expect to continue to operate this highway for the 19 years remaining in the concession.

Acapulco Scenic Bypass. In November 2012 the State of Guerrero awarded us with a 30-year concession for a toll tunnel and highway in Acapulco. The project includes a 3.3-kilometer tunnel from the Brisamar interchange to Cayao – Puerto Marques and a 4.7-kilometer highway from the tunnel entrance to the Zona Diamante section of Acapulco. The expected date of completion of construction is July 2017.

The Rio Verde-Ciudad Valles Highway. In July 2007, the Ministry of Communications and Transportation awarded the 20-year concession for a 113.2-kilometer highway between Rio Verde and Ciudad Valles in the state of San Luis Potosi to a consortium made up of our subsidiaries. The estimated total investment at December 2014 will be approximately Ps. 5,240 million. The scope of the concession includes: (i) the operation, conservation, maintenance, modernization, and widening of a 36.6 kilometer tranche from Rio Verde—Rayon; (ii) the construction, operation, conservation, and maintenance of a 68.6 kilometer tranche from Rayon—La Pitahaya; and (iii) the operation, conservation, maintenance, modernization, and widening of an 8.0 kilometer tranche from La

43

Pitahaya—Ciudad Valles. This concession includes the exclusive right for the 20-year service contract with the Mexican federal government, acting through the Ministry of Communications and Transportation. On September 19, 2008, we procured the financing for this project in the amount of Ps. 2,550 million. In August 2014, the Ministry of Communications and Transportation extended the PPP term for 4 additional years, with a termination date in August 2031. The Ministry also extended the concession for 20 additional years until August 2047. See “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Indebtedness—Rio Verde-Ciudad Valles Highway.” The concession began full operations in July 2013. On June 18, 2015, we announced that we had closed an agreement to sell to CDPQ a 49% participation in our subsidiary ICA OVT, which was established on March 19, 2015 and owns the Rio Verde-Ciudad Valles Highway concession. We expect to continue to operate this highway for the 32 years remaining in the concession.

The La Piedad Bypass. On March 24, 2009, through our wholly-owned subsidiary Libramiento ICA La Piedad, S.A. de C.V., we entered into a thirty-year concession for (i) the construction, operation, conservation and maintenance of the 21.38-kilometer La Piedad Bypass, to alleviate congestion caused by long-haul traffic between the Bajio region and western Mexico, and (ii) the modernization of 38.8 kilometers of the toll-free Federal Highway 110 in the states of Guanajuato and Michoacan and 7.32 kilometers of Highway 90. This concession began full operations in November 2012. In September 2013 the Ministry of Communications and Transportation extended the concession for 15 additional years, with a termination date in March 2054 On June 18, 2015, we announced that we had closed an agreement to sell to CDPQ a 49% participation in our subsidiary ICA OVT, which was created on March 19 2015 and owns the La Piedad Bypass concession. We expect to continue to operate this highway for the 39 years remaining in the concession.

Barranca Larga-Ventanilla Highway. On April 16 2012, the Ministry of Communications and Transportation awarded us a 30-year concession for the construction, operation and maintenance of the 104-kilometer Barranca Larga-Ventanilla toll road in the state of Oaxaca. We entered into long term financing for the project on June 15 2012. An impairment loss of Ps. 2,208 million was recognized for the investment in the Barranca Larga-Ventanilla tollroad concession. Construction cost overruns caused by social and environmental issues and updated traffic studies have shown that the project is no longer financially viable. Accordingly, ICA has suspended construction work on most of the project. ICA is currently analyzing alternatives to restore the project to financial viability.

Palmillas-Apaseo El Grande Toll Road. We were awarded a 30-year concession for the Palmillas-Apaseo El Grande Toll Road by the Ministry of Communications and Transportation in November 2012. The concession title was signed in February 2013 for a total investment of Ps. 9,359 million. In June 2013 we entered into a Ps. 5,675 million loan agreement, which was amended on September 19, 2013 to Ps. 5,450 million. The 86-kilometer, 4-lane, high specification toll road in the states of Queretaro and Guanajuato will create a new link between the Mexico City metropolitan region, the Central Mexican region and the Northern Mexican region. The concession includes nine interchanges, 29 vehicular overpasses and underpasses and calls for the construction of 15 major bridges, and is expected to start operations in 2016.

The Mitla-Tehuantepec Highway. On June 17, 2010, through our wholly-owned subsidiaries Caminos y Carreteras del Mayab, S.A.P.I. de CV, and Controladora de Operaciones de Infraestructura, S.A. de C.V., or CONOISA, we entered into a twenty-year PPP concession for the construction, operation and maintenance of the 169-kilometer Mitla-Tehuantepec federal highway in Oaxaca. The road includes three segments: Mitla-Entronque Tehuantepec II, Mitla-Santa Maria Albarradas and Lachiguiri-Entronque Tehuantepec II. The construction work is expected to take 40 months. The highway will link the city of Oaxaca with the Isthmus of Tehuantepec, increasing the connectivity of the industrial port of Salina Cruz with central Oaxaca. The modernized highway is expected to promote the economic development of the region and the communities along its route. We began the construction of this project in July 2012. In January 2012, we completed the transfer of 40% of this concession to IDEAL and now hold 60%. A rescheduling of the term of the construction works is currently under negotiation between the concessionaire and the SCT, as a result of delays in the project caused by political and social issues and delays in the delivery of rights of way outside our Company’s control.

Nuevo Necaxa-Tihuatlan Highway. In June 2007, the Ministry of Communications and Transportation awarded us a 30-year concession for the construction, operation, maintenance and preservation of the Nuevo Necaxa—Tihuatlan highway. The 85-kilometer highway is located in the states of Puebla and Veracruz. The 30-year concession, with a total investment of approximately Ps. 10,284 million, includes: (i) construction, operation,

44

maintenance, and preservation of the 36.6 kilometer Nuevo Necaxa—Avila Camacho segment; (ii) operation, maintenance, and preservation of the 48.1 kilometer Avila Camacho—Tihuatlan segment; and (iii) a long-term service contract to sustain the capacity of the highway for the Nuevo Necaxa—Avila Camacho segment, in accordance with the exclusive rights provided by the concession. This is the final tranche to complete the highway that will connect Mexico City with the port of Tuxpan in Veracruz. In June 2008, we entered into a financing agreement in the amount of Ps. 6,061 million to finance the construction of this project. See “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Indebtedness—Nuevo Necaxa—Tihuatlan.” The project was completed in the third quarter of 2014.

Rio de los Remedios—Ecatepec. We participate in the Rio de los Remedios—Ecatepec project with a 100% interest in ANESA (formerly known as Viabilis Infraestructura S.A.P.I. de C.V., or Viabilis). In 2008, we began participating in this project with a 50% interest in Viabilis, the contractor for the construction and financing of public works. In June 2009, we obtained a controlling interest in Viabilis by purchase one additional share above our existing 50% interest, allowing us an additional seat on the board of directors of Viabilis. As of such date, we consolidate ANESA. In May 2012, we completed the acquisition of the 50% interest we did not own in Viabilis, and as a result we now wholly own the company and changed its name to ANESA. The Ps. 6,568 million project relates to isolating a drainage canal and building a 25.5-kilometer toll highway in the Mexico City and state of Mexico metropolitan areas. The project calls for construction in three phases, with Phase 1 completed in July 2009 and Phase 2 completed in March 2013. As of the date of this report, we are in negotiations with the System of Highways, Airports, Related and Auxiliary Services (“SAASCAEM”) of the government of the state of Mexico regarding Phase 3 of the project. ANESA was awarded the construction contract for the project on November 15, 2004 by the SAASCAEM. The contract was amended and restated in May 2007. In June 2008, we obtained bridge loan financing for the project in the amount of U.S.$40 million structured by the Ahorro Corporacion of Spain with Caja de Ahorros Municipal de Burgos as agent for various lenders. We have repaid the bridge loan and subsequently became a lender to the project, and in February 2010 we entered into a long term financing agreement in the amount of Ps. 3,000 million with Banobras development bank. An allowance of Ps. 1,201 million was made for receivables for the Rio de los Remedios financed public works project, as a result of a change in the estimated return on the project. As of December 31, 2015, the 3 stretches of the Río de los Remedios-Ecatepec Highway have been in operation for two full years, generating real toll data, as well as the experience of the application of the resources managed by the Trust, and the assessment of periodic rate increases. By assessing this information, the cash flow analysis was estimated to the end of 2015, which is determined based on discounted future flows. Additionally, the cash flow variables were reviewed, taking into account the operating experience of the highway in the last 3 years, the inflation rate reduction observed during the year, and the rate increases that were lower than what had been projected. According to the results obtained, our management decided to define a maximum recovery term of 60 years, even though that pursuant to the construction contract, there is no deadline for the recovery of the account receivable, and an estimate for bad debt accounts was recorded in the amount of Ps.1,012 million, presented in the cost of concessions in the profit and loss statement and in other comprehensive loss items.

Port Concessions.

Lazaro Cardenas Port Terminal. In 2012, our affiliate APM Terminals Lazaro Cardenas, S.A. de C.V., or APMT-Lazaro Cardenas, of which we own 5%, signed a thirty-year agreement to design, finance, construct, operate and maintain the new “TEC II” container terminal in Lazaro Cardenas port, located on Mexico’s Pacific coast. There will be four separate stages of investment and construction. Phase I is expected to be completed in 2015 and was expected to require an investment of approximately Ps. 7,682 million. ICA was expected to perform 100% of the construction of Phase I. The construction contract for Phase I was awarded to ICA, which during 2015 received a notification of early termination. Currently the parties to the construction contract are involved I an ordinary dispute resolution proceeding. On June 2015, we completed the sale of our interest in this concession.

Water Distribution and Water Treatment Concessions

During 2014, we participated in one water treatment plant, which is currently under construction, and in three water supply systems, two of which are currently under construction. The following table sets forth certain information as of December 31, 2015, regarding the water treatment plant and water supply system concessions in which we currently participate, either through subsidiaries or affiliates. We account for all of our water projects using the equity method in our consolidated financial statements as we either consider that we have joint control over the joint venture investment, or we have the ability to significantly influence the key operating and financial decisions of the venture.

Atotonilco Water Treatment Plant. A consortium of which our subsidiary CONOISA holds 10.2% was awarded, through an international bidding process, the concession for the construction and operation of the Atotonilco water treatment plant in Tula, Hidalgo by the National Water Commission, (or “Conagua”). On January 7, 2010, the consortium entered into a final contract with Conagua. The consortium is responsible for the design, construction, electromechanical equipment and testing, as well as the operation, conservation and maintenance of the water treatment plant including electricity cogeneration and the removal and final disposition of all waste and biosolids that are produced, over the 25-year term of the agreement. The Atotonilco plant is expected to be the largest of its kind in Mexico and one of the largest in the world, with a treatment capacity of up to 42 cubic meters of wastewater per second. The plant will be located at the outlet of the Eastern Discharge Tunnel, which we are also building. The consortium was comprised of Promotora del Desarrollo de America Latina, S.A. de C.V., a subsidiary of Grupo Carso, as the leader with 40.8%, ACCIONA Agua S.A. with 24.26%, Atlatec, S.A. de C.V. (a subsidiary of Mitsui & Co., Ltd.) with 24.26%, our subsidiary CONOISA with 10.2% and other minority investors. The resources for the investment will be provided by the National Fund for Infrastructure for Ps. 4.6 billion, representing 49% of the equity capital of the consortium, and commercial bank debt. In December 2013, we entered into an agreement to sell our share of the concession to Promotora del Desarrollo de America Latina, S.A. de C.V. The agreement to sell our interest in this plant was signed on November 3, 2014 and the sale was completed in November 2014.

Aqueduct II Water Supply. In May 2007, a consortium we lead was granted a 20-year concession by the State Water Commission of Queretaro for the construction, operation, and maintenance of the Aqueduct II water supply and purification system in Queretaro state. The Aqueduct II brings water 108 kilometers from the Moctezuma River to the city of Queretaro. The required investment of Ps. 2,854 million was financed by Banco Santander with HSBC and Banorte, among others, on October 5, 2007 in the amount of Ps. 1,700 million for a 17-year period. Additionally, the National Fund for Infrastructure is contributing Ps. 872 million directly to the project. The construction of this project began in 2007. We initiated operations of the project in February 2011. The concessionaire Suministro de Agua de Queretaro, S.A. de C.V., or SAQSA, is made up of the following shareholders: ICA, as consortium leader (primarily through our subsidiary CONOISA) with 37%; Servicios de Agua Trident, S.A. de C.V., a subsidiary of Mitsui Corp with 26%; Fomento de Construcciones y Contratas (including two additional affiliates) with 26%; and Proactiva Medio Ambiente Mexico, S.A. de C.V., or PMA Mexico, with 11%. Including our interest in PMA Mexico, which is our affiliate, our direct and indirect economic interest in SAQSA is 42.39%. We account for this investment using the equity method.

El Realito Aqueduct. In 2009, a consortium we lead signed a 25-year service contract with the State Water Commission of San Luis Potosi to build, operate and maintain the El Realito aqueduct water supply and purification system. In March 2011, our subsidiary Aquos el Realito S.A. de C.V. entered into an 18-year term financing agreement for the construction of the El Realito Aqueduct project, to which it holds a long-term service agreement, in an amount up to Ps. 1,319 million. The consortium is comprised of our subsidiary Controladora de Operaciones de Infraestructura, S.A. de C.V., or CONOISA, as consortium leader, with 51% and Fomento de Construcciones y Contratas, through a subsidiary, with 49%. We account for this investment using the equity method. See Note 4 to our consolidated financial statements. We initiated operations of this aqueduct in January 2015.

Agua Prieta Water Treatment Plant. In 2009, a consortium we lead was granted a 20-year contract with the Jalisco State Water Commission for the construction and operation of the Agua Prieta wastewater treatment plant. The Ps. 2,318 million contract is a fixed price, fixed term contract with a 33-month term for construction and a subsequent 207-month term for operation. We will earn a portion of the total contract price based on our construction work, which will be set forth in a construction contract at a later date. We expect to finance the project with contributions from the Mexican federal government’s National Fund for Infrastructure, equity contributions from the consortium and commercial bank debt. In addition to ICA, which is consortium leader and holds a 50% interest, the consortium also includes ATLATEC, S.A. de C.V. with a 34% interest and Servicios de Agua Trident S.A. de C.V. with a 16% interest, both of which are subsidiaries of Mitsui & Co, Ltd. We account for this investment using the equity method. The Agua Prieta Water Treatment Plant was inaugurated in July 2014 and initiated operations in November 2014. The total investment for this project was Ps. 2,967 million.

Monterrey VI. In October 2014, a consortium led by CONOISA signed one of the first contracts under the new Public Private Partnership law in Mexico with Servicios de Agua y Drenaje de Monterrey, the water and sanitation services company of the State of Nuevo León. CONOISA has a 37.75% interest in the consortium. The bulk water delivery contract includes the construction, equipment, operation, and maintenance of the Monterrey VI Aqueduct. The 372 kilometer pipeline will have a capacity of 6 cubic meters and will increase by more than 40% the supply of potable water for the Monterrey metropolitan region. This increase ensure adequate water supplies for the next 30 years. Total investment in the project is expected to be approximately Ps. 17,684 million. The Monterrey VI Aqueduct will bring water from intake works on the Rio Panuco to the existing Cerro Prieto reservoir in Linares, Nuevo León and will pass through the states of San Luis Potosi, Veracruz, and Tamaulipas. The 84-inch diameter pipeline will have a maximum capacity of 6,000 liters per second. The project also includes six pumping stations, seven regime change tanks, a regulation tank, a pre-treatment system, and telemetry. The project has been suspended by the Water and Drainage Services of Monterrey and the consortium hasn’t had any further communication from the client. We account for the concession using the equity method.

Energy Concessions

Reynosa I Windpark. On October 17, 2014, we, through our subsidiary CONOISA, announced that we had joined a consortium to invest in and build the 60 megawatt Reynosa I Windpark in Reynosa, Tamaulipas, together with Santander Capital Structuring, S.A. de C.V. (“SCS”), the capital structuring arm of the Santander Group, which

47

focuses on investing the bank’s own capital in renewable energy, energy efficiency and climate change projects, and private equity investors.

CONOISA was expected to be the primary user of the electricity generated under long-term Power Purchase Agreements (PPAs). Some of the necessary environmental permits have been received. The Phase I project will require a total investment of approximately U.S.$151 million. CONOISA held 20% of the equity and was responsible for construction. CONOISA was also party to the asset management contract during the operation phase. SCS and private equity investors own the remaining 80%. CONOISA’s 20% stake in the project was sold to Zuma Energía, S.A. de C.V. and Zuma Energía Servicios, S.A. de C.V on March 23, 2016. Prior to the sale, the Reynosa I Windpark was accounted for as a Joint Ventures and Associated Company in our consolidated financial statements.

Discontinued operations.

As of December 31, 2015, we do not have any operations classified as discontinued operations.

In our consolidated financial statements as of and for the year ended December 31, 2014, we previously reported the project below as a discontinued operation:

SPC Projects. In 2011, we entered into two agreements to build and operate over a 22-year term two federal penitentiaries (the “SPC Project”) for a total investment of Ps. 9,890 million. Construction for the projects was completed in 2012 and the projects are now operational. The infrastructure operations relate to non-penitentiary services. In January 2014, we announced that we had signed an agreement to sell CGL a 70% equity interest in our two SPC contracts. This investment was reported as a discontinued operation. On December 5, 2014, we announced the expiration of this agreement. However, as we actively sought sale of our investment, we continued to report discontinued operations in our consolidated financial statements as of and for the year ended December 31, 2014. During 2015, after not receiving a formal offer to purchase, the administration of our Company decided to withdraw its intention to sell such assets. Consequently, at December 31, 2015, we reclassified the operations of the two SPC contracts to continuing operations for all years presented. See Note 2.d to our consolidated financial statements.

Airports

Our Airports segment accounted for 14% of our total revenues in 2015.

As of December 31, 2015, we controlled the vote of 149,932,500 shares of GACN, representing 37.48% of GACN’s capital stock. Our investment in GACN was comprised of 83,132,500 Series B Shares owned directly through our wholly-owned subsidiary Aeroinvest, and 49,766,000 Series B and BB Shares controlled through our ownership of 74.5% of the capital stock of SETA. The remaining 25.5% of SETA was owned by Aeroports de Paris Management, or ADPM. The remaining shareholders in GACN held 60.56% of its outstanding capital stock and 1.96% of the shares are held in GACN’s treasury. Because of the decrease in our interest in GACN in 2013, we continued to reassess our effective control over GACN and concluded that we retained effective control through December 31, 2014 based on our substantive rights as controlling shareholder, ability to appoint directors and executives of GACN, administration of the relevant activities of GACN and other factors. Additionally during 2015 we sold 3.09% of our shares in

48

GACN and also reassessed our effective control over it, concluding that based on our substantive rights as the controlling shareholder of the BB shares, our ability to appoint directors and executives of GACN, administration of the relevant activities of GACN and other factors we continued to effectively control GACN. Although in 2016 we have been subject to foreclosure of additional B shares in GACN and have sold an additional 50.43% of those shares, we continue to effectively control GACN through the same rights under our shareholding agreements, as further demonstrated by our ability to nominate board members in GACN’s most recent Shareholders’ Meeting held in the second quarter of 2016. See Note 17 to our consolidated financial statements. GACN is listed on the Mexican Stock Exchange and the NASDAQ Stock Market. CONOISA (as successor in interest to Aeroinvest) and ADPM have agreed that:

• The GACN Corporate Practices Committee and Audit Committee shall be comprised of at least three independent members; and

• CONOISA (as successor in interest to Aeroinvest) and ADPM shall have the right to propose at least one of the members of each Committee.

Pursuant to the consortium agreement entered into among ADPM, CONOISA (as successor in interest to Aeroinvest) and Vinci, S.A. (a corporation organized under the laws of France) on May 16, 2000, as amended and restated on April 13, 2015, the shareholders of SETA agreed that ADPM shall have the right to appoint one member of our Board of Directors and that CONOISA shall have the right to appoint two directors. Since September 14, 2005, ADPM and CONOISA (as successor in interest to Aeroinvest) are the sole parties to the consortium agreement. The right to appoint certain of our officers under the consortium agreement is allocated as follows: CONOISA shall appoint our chief executive officer, chief financial officer, human resources manager (subject to the approval of ADPM) and general counsel; ADPM shall appoint our chief operating officer and our commercial and marketing officer (subject to the approval of CONOISA). The maintenance and infrastructure officer shall be appointed by SETA.

CONOISA (as successor in interest to Aeroinvest) and ADPM have also agreed that, in accordance with our bylaws, at least one member of each of our Audit Committee and Corporate Practices, Finance, Planning and Sustainability Committee shall be appointed by SETA.

The consortium agreement also requires the unanimous vote of CONOISA (as successor in interest to Aeroinvest) and ADPM to approve (if approved at the meeting on first call): (i) the pledging or creation of a security interest in any of our shares held by SETA and the shares issued by SETA; (ii) any amendments to SETA’s bylaws or the SETA shareholders’ agreement; (iii) our merger, split, dissolution or liquidation; (iv) the amendment or termination of our bylaws, the Participation Agreement, the Technical Assistance Agreement, the technology transfer agreement or related ancillary agreements; (v) changes in our capital structure; (vi) the conversion of our Series BB shares into our Series B Shares; and (vii) any sale or transfer of shares of SETA.

Under the consortium agreement, transfers by either of CONOISA or ADPM of its respective shares in SETA to an unaffiliated party are subject to limited rights of first refusal in favor of the non-transferring shareholder, and such transfers by CONOISA are subject, under certain conditions, to tag-along rights in favor of ADPM. The consortium agreement also sets forth a put option in favor of ADPM pursuant to which, under certain conditions, ADPM may require CONOISA to purchase all of ADPM’s shares in SETA in case of a disagreement between the parties with respect to a matter to be decided by our or SETA’s Board of Directors or shareholders. Through GACN, we operate 13 airports in the Central North region of Mexico pursuant to concessions granted by the Mexican government, including the Monterrey airport, which accounted for approximately 44.5% of GACN’s revenues in 2015 and 42% in 2014. The airports serve a major metropolitan area (Monterrey), three tourist destinations (Acapulco, Mazatlan and Zihuatanejo), two border cities (Ciudad Juarez and Reynosa) and seven regional centers (Chihuahua, Culiacan, Durango, San Luis Potosi, Tampico, Torreon and Zacatecas). All of the airports are designated as international airports under Mexican law, meaning that they are all equipped to receive international flights and maintain customs, refueling and immigration services managed by the Mexican government.

49

In October 2008, GACN acquired 90% of the shares of Consorcio Grupo Hotelero T2, S.A. de C.V., which has the rights to develop and operate a 287-room hotel and approximately 5,000 square meters of commercial space inside the new Terminal 2 of the Mexico City International Airport under a 20-year lease agreement with the Mexico City International Airport. NH Hoteles, S.A. de C.V., a Spanish company, owns the other 10%. For the year ended December 31, 2015, total revenues of the hotel amounted to Ps. 212 million. Annual average occupancy increased to 80.5% in 2015 from 79.6% in 2014. In 2015, the annual average rate per room was Ps. 1,968, as compared to Ps. 1,817 in 2014.

The substantial majority of the Airports segment’s revenues are derived from providing tariff-regulated services, which generally are related to the use of airport facilities by airlines and passengers. For example, approximately 66.4% of GACN’s total revenues in 2015 were earned from aeronautical (tariff-regulated) services such as the provision of aircraft parking, passenger walkways and airport security services. Changes in revenues from aeronautical services are principally driven by the passenger and cargo volume at the airports. All of our revenues from aeronautical services are also affected by the “maximum rates” the subsidiary concessionaires are allowed to charge under the price regulation system established by the Ministry of Communications and Transportation. The “maximum rate” system of price regulation that applies to aeronautical revenues is linked to the traffic volume (measured in workload units) at each airport; thus, increases in passenger and cargo volume generally permit greater revenues from aeronautical services. In December 2010, the Ministry of Communications and Transportation approved the master development programs for each of our Airport segment’s subsidiary concession holders for the 2011 to 2015 period. These programs will be in effect from January 1, 2011 until December 31, 2015. In December 2015, the Ministry of Communications and Transportation approved the master development programs for each of our Airport segment’s subsidiary concession holders for the 2016 to 2020 period. These five-year master development programs will be in effect from January 1, 2016 until December 31, 2020.

The Airports segment also derives revenues from non-aeronautical activities, which principally relate to the commercial, non-aeronautical activities carried out at the airports, such as the leasing of space in terminal buildings to restaurants and retailers. Revenues from non-aeronautical activities are not subject to the system of price regulation established by the Ministry of Communications and Transportation. Thus, non-aeronautical revenues are principally affected by the passenger volume at the airports and the mix of commercial activities carried out at the airports. While we believe aeronautical revenues will continue to represent a substantial majority of future total revenues, we anticipate that the future growth of revenues from commercial activities will exceed the growth rate of this division’s aeronautical revenues.

The airports are also focusing their business strategy on generating new services and products to diversify our revenue, such as hotel services, air cargo logistics services and real estate services. They plan to develop land not needed for aeronautical operations at all of the airports for industrial, logistical or commercial uses that are directly or indirectly related to airport activities in order to strengthen the airports’ role as focal points of economic development in the cities where they are located. As a result of such efforts, revenues from diversification activities increased by 38.4% in the year ended December 31, 2015 as compared to the year ended December 31, 2014.

(2) Revenues per terminal passenger are calculated by dividing the total revenues for each airport by the number of terminal passengers for each airport. The result has been rounded to the decimal.

Competition

The Acapulco, Mazatlan and Zihuatanejo International Airports are substantially dependent on tourists. These airports face competition from competing tourist destinations. We believe that the main competitors to these airports are those airports serving other vacation destinations in Mexico, such as Los Cabos, Cancun and Puerto Vallarta, and abroad, such as Puerto Rico, Florida, Cuba, Jamaica, the Dominican Republic, other Caribbean islands and Central America.

In the future, we may face competition from Aeropuerto del Norte, an airport near Monterrey operated by a third party pursuant to a concession. Historically, Aeropuerto del Norte has been used solely for general aviation operations. The state of Nuevo Leon has requested in the past that the Ministry of Communications and Transportation amend Aeropuerto del Norte’s concession to allow it to serve commercial aviation operations. To date, the Ministry of Communications and Transportation has not amended Aeropuerto del Norte’s concession. The Ministry of Communications and Transportation may authorize such an amendment, and commercial aviation flights may operate from Aeropuerto del Norte in the future. In addition, we understand that Aeropuerto del Norte is not capable of accommodating commercial passenger traffic with its current infrastructure.

Excluding our airports servicing tourist destinations, our airports currently do not face significant competition.

Corporate and Other

Our Corporate and Other segment includes all of our real estate operations, including our affordable entry-level housing operations as well as our corporate operations through our subsidiary Grupo ICA S.A. de C.V. See “Item 4. Information on our Company—History and Development of our Company—Divestitures.” In 2015, our Corporate and Other segment accounted for 2% of our total revenues.

51

Our housing operations during 2015 covered all stages of the housing industry, performing and procuring architectural and engineering design, facilitating buyer financing and constructing and marketing homes. We subcontracted some construction services, such as urbanization.

As of December 31, 2015, due to various market factors, including third party offers received, we recorded an adjustment in the determination of net realizable value of inventories of Ps. 1,757 million. See Note 10 to our consolidated financial statements.

The principal raw materials we require for our housing operations are cement, steel, construction aggregates, doors, windows and other housing fixtures.

In 2010, we expanded our operations in the housing operations by increasing our stake in Los Portales, a real estate development company in Peru, from 18% to 50%, and we participated in several new housing development projects in Mexico, including a joint venture with Prudential Investment Management, Inc. to develop social interest housing with Prudential Real Estate Investors, S. de R.L. de C.V. During 2015, 2014 and 2013 we sold 629, 1,859 and 1,513 homes, respectively.

Additionally we continued to develop certain vertical residential properties, and other selected mid-rise and high-rise properties that together make up our vertical housing business.

Our housing operations compete primarily with large and mid size Mexican public housing developers such as Corporacion GEO, S.A.B. de C.V., Grupo Javer, S.A. de C.V., Grupo Sadasi, S.A. de C.V., Inmobiliaria Ruba, S.A. de C.V., and Consorcio Ara S.A.B. de C.V., as well as regional competitors.

Recently, the industry has been affected by instability due to changes in government housing policies and access to sources of funding has become increasingly limited. Several of our competitors in the industry recently entered into reorganization proceedings (Concurso mercantil), which has contributed to instability among other companies in the industry. The outlook of the housing sector remains uncertain.

Geographical Distribution of Revenues

Revenues from foreign operations accounted for approximately 31% of our revenues in 2015, 34% of our revenues in 2014 and 24% of our revenues in 2013. The decrease in 2015 over 2014 of the percentage of our revenues derived from foreign operations principally reflected a decreased in contribution from our projects in Panama which were completed or near completion during the period, and which contributed 79% less to revenues in 2015 as compared to 2014, as well as after the application of the equity method in San Martin during the fourth quarter of 2015 which represented a 20% decrease in revenues.

The following table sets forth our revenues for Mexico and abroad for each of the years in the three-year period ended at December 31, 2013, 2014, and 2015.

	Year Ended December 31,
	2015					2014					2013

Mexico		Ps. 22,708		69	%		Ps. 26,060		68	%		Ps. 24,452		76	%
Other countries		10,416		31	%		12,269		32	%		7,905		24	%
Total revenues		Ps. 33,124		100	%		Ps. 38,329		100	%		Ps. 32,358		100	%

52

Approximately 16% of our Civil Construction backlog as of December 31, 2015 is related to projects outside Mexico (as compared to approximately 11% as of December 31, 2014) and approximately 16% of our Civil Construction backlog as of December 31, 2015 was denominated in foreign currencies (principally U.S. dollars) (as compared to approximately 11% of our backlog as of December 31, 2014).

Foreign projects may be more difficult to supervise due to their greater distances from our principal operations. Foreign projects require familiarity with foreign legal requirements and business practices. In contrast to domestic infrastructure projects, foreign projects also typically do not allow us to benefit from our reputation and past experiences with Mexican government officials and private-sector individuals. Although we are active abroad, we have sought to be more selective than in the past when bidding for international projects. See “Item 5. Operating and Financial Review and Prospects—Operating Results.”

Environmental Matters

Our Mexican operations are subject to both Mexican federal and state laws and regulations relating to the protection of the environment. At the federal level, the most important of these environmental laws is the Mexican General Law of Ecological Balance and Environmental Protection, or the Ecological Law (Ley General de Equilibrio Ecologico y Proteccion al Ambiente). Under the Ecological Law, rules have been promulgated concerning water pollution, air pollution, noise pollution and hazardous substances. Additionally, the Mexican federal government has enacted regulations concerning the import, export and handling of hazardous materials and bio-hazardous wastes. The waste and water treatment plants that are operated by one of our equity investees are subject to certain waste regulations, including for bio-hazardous waste. The Mexican federal agency in charge of overseeing compliance with the federal environmental laws is the Ministry of the Environment and Natural Resources (Secretaría de Medio Ambiente y Recursos Naturales). The Ministry of the Environment and Natural Resources has the authority to enforce Mexican federal environmental laws. As part of its enforcement powers, the Ministry of the Environment and Natural Resources can bring administrative and criminal proceedings against companies that violate environmental laws, and has the power to close non-complying facilities. We believe that we are in substantial compliance with Mexican federal and state environmental laws. Changes in Mexican federal or state environmental laws could require us to make additional investments to remain in compliance with such environmental laws, and changes in the interpretation or enforcement of such laws could cause our operations to cease to be in compliance with such laws. Any such event could have an adverse effect on our financial condition and results of operations.

Since 1990, Mexican companies have been required to provide the Ministry of the Environment and Natural Resources with periodic reports regarding their production facilities’ compliance with the Ecological Law and the regulations thereunder. These reports are required to include information with respect to environmental protection controls and the disposal of industrial waste. We have provided the information required by these reports to the Ministry of the Environment and Natural Resources. There are currently no material legal or administrative proceedings pending against us with respect to any environmental matter in Mexico, and we do not believe that continued compliance with the Ecological Law or Mexican state environmental laws will have a material adverse effect on our financial condition or results of operations, or will result in material capital expenditures or materially adversely affect our competitive position. However, financing institutions providing credit for projects on a case—by-case basis now and in the future could require us to comply with international environmental regulations that may be more restrictive than Mexican environmental regulations.

Through our Environmental Management Systems—which have ISO 14001:2004 certification—and our material and human resources, we manage projects from the bidding phase through completion of construction. In the case of concessions, we manage the remediation of our projects, seeking to ensure that the necessary studies are conducted (among them identification of species of flora and fauna listed in NOM-059-SEMARNAT-2010

53

“Environment protection – Native Mexican species of animal and plant wildlife categories of risk and specifications for inclusion, exclusion or change. This year 3,031 species of flora and fauna were recovered in construction projects, of which 2,517 were rescued and preserved corresponding to endangered species, and the environmental impact mitigation activities have been proposed before projects begin. We have promoted the management of natural resources through operational eco-efficiency. As part of the contractual conditions for infrastructure construction, we have established guidelines with our clients in order to use natural resources optimally and reduce emissions of greenhouse gases (GHG) emissions from fossil fuels. During the course of our projects, through external audits and consultation with environmental authorities and clients, we verify compliance with agreed-upon environmental protection activities, placing special emphasis on those relating to biodiversity through flora and fauna rescue programs, reforestation, environmental monitoring, soil protection and land slope stabilization, and waste management, among others. In projects outside of Mexico, including within the Panama Canal zone, we are also required to comply with environmental laws by applicable authorities. We believe we are in substantial compliance with environmental laws to which we are subject.

Sustainable Infrastructure for Development

In 2011, in an effort to measure and improve our sustainability performance, we began publishing an annual Sustainability Report providing a snapshot of our operations’ economic, environmental and social impacts. Our annual report expands upon and deepens our engagement with a diverse range of stakeholders—including investors, local communities in which we operate, employees and their families, suppliers and other business partners—by explaining how we respond to their expectations and interests. Since 2013 we have conducted our integrated activities in accordance with the guidelines of the Global Reporting Initiative (GRI) V4 and the International Integrated Reporting Council (IIRC) frameworks.

By creating and maintaining a culture of sustainability, we seek to achieve long-term business success that aligns with the interests and needs of other stakeholders. In the recent years we have sought to redouble our efforts related to our zero-tolerance policy towards corruption. We have developed an anticorruption program that involves training of our employees, testing employees about conflicts of interest, as well as specific training and follow-up in our procurement area. In January 2013, our Board of Directors approved our first Code of Ethics and Conduct for Providers, Contractors and Business Partners. For two years in a row, ICA was the only construction and engineering company of Latin America listed in the Dow Jones Sustainability Emerging Markets Index for 2014-2015. In 2014, we kept our commitments on sustainability as Global Compact signatories as members of the Council Network for Mexico (Consejo de la Red de México) and as volunteers in the emissions report following the guidelines of the Carbon Disclosure Project (CDP). We also chaired the Sustainability Subcommittee of the Mexican Stock Exchange (Subcomité de Sustentabilidad de la Bolsa Mexicana de Valores) and the Infrastructure Comission of the Business Coordination Council (Consejo Coordinador Empresarial) as members of the World Business Council for Sustainable Development. In order to promote sustainability and evaluate the quality of our projects, we started collaboration with the Zofnass Program for Sustainable Infrastructure of Harvard Design School. In 2014, two case studies were conducted on ICA’s projects: the Nuevo Necaxa-Tihuatlán Highway and the Mayab Highway. By analyzing these two cases, we sought to create guidelines for evaluating and improving the performance of sustainability matters in our projects. Additionally, in 2014, we also started a strategic alliance with the Network for Sustainability in Emerging Markets of the German Development Cooperation (GIZ) to share expertise and best practices relating to environmental assets.

Finally, our culture of sustainability has allowed us to focus on specific composite initiatives to be implemented in the short, medium and long term activities and to consolidate our sustainability strategy.

Item 4A. Unresolved Staff Comments

None.

Item 5. Operating and Financial Review and Prospects

The following discussion should be read in conjunction with our consolidated financial statements and the notes thereto. Our consolidated financial statements have been prepared in accordance with IFRS. We organize our reportable segments based on internally reported financial segment information, which is presented to our management through business unit reports. Our management regularly reviews this information to aid in operational decision-making, including regarding resource allocation, and for performance evaluation.

For the years ended December 31, 2015, 2014 and 2013, we have five reportable segments: Civil Construction, Industrial Construction (representing our 50% interest in ICA Fluor), Airports, Concessions and Corporate and Other.

Overview

We are a Mexican company principally engaged in construction and the operation of infrastructure projects under long-term concession or service agreements. Approximately 69% of our revenue in 2015 was generated in Mexico. As a result, our results of operations are substantially affected by developments in Mexico and Mexican public spending on large infrastructure projects. Our results of operations also vary from period to period based on the mix of projects under construction, the contract terms relating to those projects, the volume of traffic on our highway concessions and in our airports, and conditions in the Mexican housing market, among other factors.

55

In recent years, our results of operations have deteriorated as a result of a lower volume of construction work performed and declining margins across several of our business segments. As a result of our declining financial performance, we increasingly were required to fund our operations through additional indebtedness. In 2015, our operating results were further adversely affected by the depreciation of the peso relative to the dollar. By the end of 2015, these factors led to a liquidity crisis, which limited our ability to repay our indebtedness and make other required payments, including tax payments and payments to suppliers.

As of December 31, 2015, as a result of the developments described below, our Company’s short-term liabilities exceeded current assets by Ps. 25.6 billion and our Company had a stockholders’ deficit with respect to equity held by controlling interests of Ps. 3.0 billion. Additionally, we had net losses of Ps. 19.7 billion and Ps. 2.0 billion during the years ended December 31, 2015 and 2014, respectively. These results and the matters described below raise substantial doubt about our ability to continue as a going concern. Our Company’s financial statements have been prepared under the assumption that we will continue as a going concern, which assumes the realization of our assets and the settlement of our liabilities and obligations in the normal course of business. Consequently, the accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Lack of growth in our backlog, low customer base recovery, high fixed costs, and losses incurred in projects abroad and other businesses, such as housing, contributed to the imbalance in our short-term cash flow. This lack of liquidity has significantly affected the fulfillment of our obligations, resulting in delays in tax payments, payments to suppliers and payment of debt service.

Management of our Company has been implementing a series of initiatives aiming at allowing us to regain financial flexibility and improve the efficiency and productivity of our operations. Management is considering various options, including negotiations with its current bondholders and certain suppliers to restructure our debt and other obligations. We have engaged and expect to continue to engage in discussions with advisors, secured creditors, unsecured creditors and potential investors in order to evaluate potential restructuring strategies. Additionally, we are analyzing the feasibility of the sale of certain non-core assets, and the partial realization of investments to allow us to obtain access to liquidity sources. We retained financial advisors to advise us in evaluating debt-restructuring alternatives to implement a long-term solution to our capital structure and debt service requirements.

Recent Developments

Interest and Principal Payment Defaults. In order to preserve the necessary cash to continue our operations and as part of our operational and financial restructuring process, we suspended payments under our unsecured debt beginning in the fourth quarter of 2015:

• In 2015, we did not make a U.S.$31 million scheduled interest payment due November 30, 2015 on our 2024 Notes. In 2016, we did not make a U.S.$6 million scheduled interest payment due January 25, 2016 on our 2017 Notes and we did not make a U.S.$22 million scheduled interest payment due February 4, 2016 on our 2021 Notes. Under the indentures governing the Senior Notes, the noteholders have the right to accelerate this debt.

• Our defaults under the Senior Notes resulted in cross-defaults under certain other corporate debt of our Company starting in December 2015. As a result, certain creditors foreclosed on the collateral securing our corporate debt or initiated other remedial actions against us . As of the date of this report, we continue to suspend payment on unsecured debt in order to preserve liquidity and creditors have continued to foreclose on collateral guaranteeing secured debt. For more information, see “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Indebtedness.”

• We have been pursuing negotiations with financial creditors to restructure our debt.

Cost Reduction Initiatives and Organizational Changes. As part of the measures we are adopting to improve our financial position, we are pursuing a significant cost reduction plan, in addition to implementing certain organizational changes.

56

We continue to delay payments to certain service suppliers and creditors and to delay payment of taxes. In addition, we are in the process of reducing our workforce, divesting non-productive assets and reducing the scope of our operations. Our workforce of 22,116 total employees (of which 9,898 are administrative staff) as of December 31, 2015 represents a reduction of 9,186 total employees and 2,295 administrative staff employees as compared to December 31, 2014. Our workforce of 18,069 total employees (of which 8,473 are administrative staff) as of April 30, 2016 represents a reduction of 14,647 total employees and 4,072 administrative staff employees as compared to April 30, 2014. Our Company is also preparing a strategic exit from our international businesses as well as its businesses related to housing and real estate.

• We announced a series of operational changes, including the:

• appointment of Guadalupe Phillips Margain as Chief Restructuring Officer; and

• appointment of Luis Zárate Rocha as CEO and Pablo Garcia Aguilar as CFO, in addition to other changes in operating management.

• In addition, we are prioritizing efficient utilization of the funds assigned to our projects.

Effects of Devaluation. Since the end of 2014, the Mexican peso has depreciated significantly against the U.S. dollar, which has resulted in an increase in the cost of servicing our U.S. dollar-denominated debt. Given the significant decline in our revenues, which are principally earned in Pesos, we are not able to enter into hedging arrangements to adequately protect against the increased exchange rate risk. Our financial condition and results of operations may continue to deteriorate if the peso continues to depreciate against the dollar during 2016.

A. OPERATING RESULTS

Certain U.S. Dollar amounts have been translated from Mexican pesos for convenience purposes at an exchange rate of Ps. 17.34 per U.S.$1.00, the free market exchange rate for Mexican pesos on December 31, 2015, as reported by Banco de Mexico.

Our operations are divided into the following five segments: (1) Civil Construction, (2) Industrial Construction, (3) Concessions, (4) Airports, and (5) Corporate and Other.

Consolidated Results of Operations for the Three Years Ended December 31, 2015

Total Revenues

Total revenues decreased 14% in the year ended December 31 2015 as compared to the year ended December 31, 2014. This decrease was primarily the result of (i) delays in the execution of works of certain projects in Mexico, including Barranca Larga – Ventanilla Highway, Mitla-Tehuantepec Highway, Nuevo Necaxa Tihuatlan Highway and the Kantunil- Cancun highway to Playa del Carmen; (ii) the deconsolidation in the fourth quarter of 2015 of the construction contracts held by San Martin in Peru, as a result of the reduction of our ownership from 51% to 31.2%; (iii) income recognized in 2014 from the initial recognition of market value of land in Los Faros, Panama; and (iv) the completion of several projects in Central and South America. This was partially offset by a 90% increase in revenue from Facchina, which was Ps. 5,112 million in the year ended December 31, 2015 as compared to Ps. 2,685 million in the year ended December 31, 2014, as a result of the inclusion of a full year of consolidation in 2015. Revenues in the Corporate and Other segment also decreased, due to the slowdown in the real estate business.

Total revenues increased 18% in the year ended December 31 2014 as compared to the year ended December 31 2013. This increase was primarily the result of the favorable performance of our Construction segment’s works contracted in Mexico, the consolidation effective in April 2014 of Facchina in the U.S., the high rates of vehicle traffic growth in the Concessions segment and the continued increases in passenger traffic in our Airports segment.

57

The following table sets forth the revenues of each of our segments and divisions for each of the years in the three-year period ended December 31, 2015. The revenues of our Industrial Construction segment are not reflected in our consolidated revenues, but are incorporated in our consolidated results through our share in results of joint ventures and associated companies. See Note 41 to our consolidated financial statements.

Total		Ps. 33,124			100	%		Ps. 39,428			—			Ps. 32,358			—

During 2014, we recognized a gain of an adjustment to fair value of Ps. 1,099 million for the acquisition in 2014 by our Panamanian subsidiary, State Town Corporation, S.A., of a property located in Panama through an auction process for U.S.$49 million, and after we acquired the property we cancelled a past due receivable owed to us in connection with construction work on the property. The property is composed of the land and the foundations for the construction of three towers in Panama City. Our management determined that the property, including the foundations, should be designated as real estate inventory as it was considering developing a real estate project on the property at the time. At December 31, 2015, and related to our announced financing restructuring process, we no longer had a short-term plan to develop the land, and there, we wrote down inventories to net realizable value for Ps. 1,040 million, resulting in a total value of the land of Ps. 1,123 million (considering the effects of exchange rate on the inventory). See Note 10 to our consolidated financial statements. In connection with this transaction, we entered into a bank loan agreement with Global Bank for U.S.$40 million with a fixed interest rate of 7.5% and a maturity date of July 2016. This loan was guaranteed by our shares in State Town Corporation, S.A. and the real estate inventory described above is pledged as collateral.

Gross Profit (Loss)

Gross profit (loss) is calculated as the sum of construction revenues, concession revenues, and sales by assets and other, less their respective costs, and does not include the line item “fair value upon recognition of real estate inventories.”

Gross profit (loss) decreased by Ps 11,989 million to a gross loss of Ps. (3,798) million in the year ended December 31 2015, as compared to a gross profit of Ps. 8,192 million in the year ended December 31 2014. The decline in gross profit (loss) was mainly due to recognition in 2015 reserves for doubtful accounts receivable for Ps. 5,801 million, an adjustment in the determination of net realizable value of inventories of Ps. 1,560 million; an, and impairments to investment properties and concession assets of Ps. 2,403 million. See Note 2(b) to our consolidated financial statements. Our greatest gross profit increase was in the Airports segment. Gross profit (loss) as a percentage of total revenue decreased to (11)% in the year ended December 31 2015 compared to 21% in the year ended December 31 2014, primarily due to the aforementioned impairments.

Gross profit increased 17% to Ps. 8,192 million in the year ended December 31 2014 compared to Ps. 7,954 million in the year ended December 31 2013. The growth in gross profit was mainly due to higher volume of traffic in the Concessions segment and a growth in the passenger rate in the Airports segment. Our greatest gross profit increase was in both our Concessions and Airports segments. Gross profit as a percentage of total revenue decreased to 21% compared to 25% in the year ended December 31 2013, primarily due to construction contracts that were executed in the year ended December 31 2014 with a smaller margin.

General Expenses

Selling, general and administrative expenses decreased 0.3% to Ps. 3,057 million in the year ended December 31, 2015 compared to Ps. 3,066 million in the year ended December 31 2014. Selling, general and administrative expenses as a percentage of total revenue increased to 9.2% in the year ended December 31 2015 compared to 7.8% in the year ended December 31 2014. The increase as a percentage of total revenue was due primarily to lower revenues generated during the year ended December 31 2015 as compared to revenues generated in the year ended December 31 2014, despite the stability in general expenses from 2014 to 2015.

Selling, general and administrative expenses increased 2% to Ps. 3,066 million in the year ended December 31 2014 compared to Ps. 3,012 million in the year ended December 31 2013. Selling, general and administrative expenses as a percentage of total revenue decreased to 7.8% in the year ended December 31 2014 compared to 9.3% in the year ended December 31 2013. The decrease as a percentage of total revenue was due primarily to greater revenues in the year ended December 31 2014 compared with revenues from the year ended December 31 2013 principally due to the incorporation of Ps. 2,685 million of revenues from Facchina.

Other Income and Expenses, Net

In the year ended December 31 2015, our net other income (expenses) was Ps. 458 million in net other income, compared to net other expenses of Ps. (181) million in the year ended December 31 2014. Net other income (expenses) in the year ended December 31,2015 was mainly comprised of (i) Ps. 507 million in losses as a result of restructuring costs related to severance payments, (ii) Ps. 128 million as a result of a gains from the deconsolidation of San Martin, which we ceased consolidating in October 2015 due to our loss of control over the entity, as our shareholding decreased from 51% to 31.2%, (iii) Ps. 112 million gain from the sales of Punta Condesa Group, (iv) Ps. 163 million of a gain from adjusting the contingent consideration for the acquisition of Facchina, (v) Ps. 209 million gain from the sale of equity method investments; and (vi) gains related to the sale of property, plant and equipment for Ps. 228 million.

In the year ended December 31 2014, our net other income (expenses) was Ps. (181) million, compared to net other income of Ps. 61 million in the year ended December 31 2013. Net other income (expenses) in the year ended December 31, 2014 is mainly comprised of (i) Ps. 194 million in additional consideration for the acquisition of San Martín Contratistas Generales, S.A., or San Martin, compared to Ps. 544 million in the year ended December 31 2013, (ii) Ps. 17 million in loss on sales of shares mainly related to the Aguas Tratadas del Valle de Mexico consortium (“ATVM”), compared to a Ps. 587 million gain in the year ended December 31 2013 related to the sale of RCO and (iii) Ps. 10 million in gain on sales of property, plant and equipment.

Operating Income (Loss)

The following table sets forth operating income or loss of each of our segments for each of the years in the three-year period ended December 31, 2015. The operating income of our Industrial Construction is not reflected in our consolidated operating income, but is incorporated in our consolidated results through our share in results of joint ventures and associated companies.

	Year Ended December 31

Operating income (loss) decreased by Ps. 12,440 million, from an operating income of Ps. 6,044 million for the year ended December 31, 2014 to an operating loss of Ps. (6,396) million for the year ended December 31, 2015. This decrease was driven primarily by the factors discussed above within gross profit (loss) related to adjustments for the allowance for doubtful accounts, determination of net releasable value of inventories and impairments to investment properties and concession assets, the decrease in revenue as a result of the slowdown in various projects as well as adjustments for impairments of assets, coupled with the fact that certain construction projects adjusted their margins at year end.

Operating income increased by 21% for the year ended December 31, 2014 from the year ended December 31, 2013. This increase was driven primarily by an adjustment to fair value on initial recognition of real estate inventories with respect to the Panama City property. The adjustment, which took into account the characteristics and location of the property, was for Ps. 1,099 million, and is presented in fair value on initial recognition of real estate inventories in our consolidated statement of results and other comprehensive income (loss).

Civil Construction

The following table sets forth the revenues and operating income of the Civil Construction segment for each of the years in the three-year period ended December 31, 2015.

	Year Ended December 31,
	2015			2014			2013
	(Millions of Mexican pesos)

Operating income (loss)		(7,355	)		1,457			891
Operating margin		(36	)%		6	%		4	%

Revenues. The 20% decrease in the Civil Construction segment’s revenues in the year ended December 31, 2015 from the year ended December 31, 2014 is principally due to (i) delays in the execution of works of certain projects in Mexico, including Barranca Larga – Ventanilla Highway, Mitla-Tehuantepec Highway and the Lazaro Cardenas Port Terminal; (ii) the deconsolidation of construction and mining contracts held by San Martin in Peru in October of 2015, as a result of the reduction in our share ownership of San Martin from 51% to 31.2%; (iii) income recognized in 2014 derived from the initial recognition of market value of land in Los Faros, Panama; and (iv) the completion of several projects in Central and South America. This decrease was partially offset by increased revenues from Facchina from Ps. 2,685 million in the year ended December 31, 2014 to Ps. 5,112 million in the year ended December 31, 2015. The following six projects together contributed 71% of revenues in this segment in 2015: Facchina, Mitla – Tehuantepec Highway, certain San Martin projects, Lázaro Cárdenas Port Terminal, Barranca Larga Ventanilla Highway and Palmillas—Apaseo El Grande Toll Road.

The 19% increase in the Civil Construction segment’s revenues in 2014 from 2013 is principally due to the inclusion of the amounts related to the Facchina acquisition in April 2014, which contributed 65% of this increase. The remaining increase was principally related to the revenues from the Mitla-Tehuantepec project. The following six projects together contributed 52% of revenues in 2014: Mitla-Tehuantepec, Barranca Larga Ventanilla, Avenida Domingo Diaz, Northern Corridor, Facchina and certain projects in the San Martin subsidiary.

Additionally, during 2014, the Civil Construction segment recognized a gain of Ps. 1,099 million upon the acquisition of a property in Panama, acquired in exchange for a past due receivable owed to us in connection with the construction work on the property.

60

Operating Income. Operating income for the Civil Construction segment decreased by Ps. 8,812 million to an operating loss of Ps. (7,355) million in the year ended December 31 2015 as compared to operating income of Ps. 1,457 million in the year ended December 31 2014, primarily due to (ii): the deconsolidation of construction and mining contracts held by San Martin in Peru in October 2015, as a result of the reduction in our share ownership of San Martin from 51% to 31.2%, due to recognition in 2015 of reserves for doubtful accounts receivable for Ps. 5,801 million.

Operating income for the Civil Construction segment increased by 64% in the year ended December 31, 2014 from the year ended December 31, 2013, primarily due to the loss on sale of shares for an amount of Ps. 544 million in the year ended December 31, 2013, which reduced the operating margin, as well as provisions made in the year ended December 31, 2013, for doubtful accounts receivable.

Concessions

The following table sets forth the revenues and operating results of our Concessions segment for each year in the three-year period ended December 31, 2015.

	Year Ended December 31,
	2015			2014			2013
	(Millions of Mexican pesos)

Operating Income		135			3,318			3,448
Operating Margin		2	%		44	%		51	%

The following table sets forth the material revenue streams in our Concessions segment for each year in the three-year period ended December 31, 2015:

	Year Ended December 31,
	2015				2014				2013
	(Millions of Mexican pesos)		(Percent of Total)		(Millions  of Mexican pesos)		(Percent of Total)		(Millions of Mexican pesos)		(Percent of Total)
Tolls		Ps. 2,293		31%		Ps. 2,059		27%		Ps. 2,015		30%
Construction		849		12		1,126		15		941		14
Financing		3,484		48		3,566		47		3,155		47
Other		685		9		845		11		655		10
Total		Ps. 7,311		100%		Ps. 7,596		100%		Ps. 6766		100%

Revenues in the Concessions segment are generated from various sources, as noted in the table above. Tolls represent the collection of fees from the operation of our concessions, which generally stems from use of toll roads, fees for the availability and use of toll-free roads and fees by volume of treated water delivered to municipalities. Construction revenues are comprised of construction on our concession assets pursuant to IFRS Interpretations Committee Interpretation No. 12 (“IFRIC 12”), Concession Arrangements. The first phase of development of a concession is the construction or rehabilitation of the asset, after which the operation and maintenance phase takes place over a specified period. To carry out the construction phase of a project, our respective concessionaire subsidiary subcontracts construction, entering into an EPC contract with a construction company. If such construction company is a related party that we consolidate, those construction revenues are recognized by our construction subsidiary in the Civil Construction segment. In addition, because our concessionaire subsidiary has entered into a construction and operating agreement with the grantor of the concession, it also recognizes construction revenues within the Concession segment pursuant to IFRIC 12. Upon consolidation, the construction revenues recognized by our concessionaire subsidiary are eliminated from the concession segment such that solely construction revenues recognized pursuant to IFRIC 12 are recognized only in the Civil Construction segment. However, segment results in our consolidated financial statements for both the Civil Construction and Concession segments include the related construction revenues. The information in the tables herein solely reflects external revenues and thus includes intercompany eliminations. For the years ended December 31, 2015, 2014 and 2013, intersegment revenues as a result of the above accounting treatment for construction services accounted for

Ps. 2,599 million, or 36%, Ps. 1,856 million, or 24% and Ps. 2,349 million, or 35%, respectively, of our Concessions segment revenues. The increase in intersegment revenues in the year ended December 31, 2015 was principally due to the fact that the Barranca Larga Ventanilla Highway and Palmillas - Apaseo el Grande Toll Road projects were in a more advanced construction phase as compared to the year ended December 31, 2014. The decrease in intersegment revenues in the year ended December 31, 2014 was principally due to the completion of the construction stages of several concessioned projects, such as, La Piedad Bypass and the Rio Verde – Ciudad Valles Highway. The decrease in intersegment revenues in the year ended December 31, 2013 was principally due to a decrease in intersegment contracts between our construction company and our concession companies, principally due to the completion of construction work under the SPC contracts in the year ended December 31, 2012.

Our concessionaire subsidiary may also enter into an EPC contract with a third party, as is the case of construction of rights of way and environmentally related construction such as environmental impact assessments. In such cases, our construction subsidiary does not perform any construction services, and therefore does not recognize any construction revenues; our concessionaire subsidiary, however, continues to recognize construction revenues pursuant to the guidance in IFRIC 12, which are disclosed in the table above.

The Concessions segment also contains financing income and other income. Financing income is composed of two sources: (i) the reimbursement of the cost of financing obtained to build infrastructure assets granted under concession arrangements and (ii) interest income earned on concession assets accounted for as long-term accounts receivable. Income from other sources is composed primarily of conservation and maintenance of highways and construction income related to construction by third parties.

Revenues. The Concessions segment’s revenue was Ps. 7,311 million in the year ended December 31, 2015. The 4% decrease in revenue over 2014 was due to the decrease in finance income related to Rio de los Remedios – Ecatepec, SPC Projects and Kantunil – Cancun Highway . The revenues described above are not eliminated because they are not consolidated in the Civil Construction segment.

The Concessions segment’s revenue was Ps. 7,595 million in the year ended December 31, 2014. The 12% increase in revenue over 2013 was due to an increase in finance income related to the Rio de los Remedios Highway, Barranca Larga Ventanilla Highway and Palmillas – Apaseo El Grande Toll Road projects, as well as an increase in construction revenues recognized in the Concessions segment related to the Scenic Bypass. The revenues described above are not eliminated because they are not consolidated in the Civil Construction segment.

The segment had eight highways, two tunnels, four concessioned water projects, two social infrastructure projects, and one energy project as of December 31, 2015. Of these 16 concessions, 11 were operational, four were under construction and one under development phase at year end. The source of revenues in the Concessions segment depends on the mix of concessions under construction versus in operation and the nature of those concessions (financial versus intangible) as well as our active management of our investments in the segment, including whether we hold them to the end of the term or sell all or part of our interest in them. Therefore, revenue streams may vary from year to year. For example we have recently experienced a trend of increased construction revenues and financial income in this segment, as we enter into new concessions in the construction phase, which are classified as financial, as opposed to intangible, assets. This trend may change as a result of the foregoing factors.

Operating Income. The Concessions segment reported a 96% decrease in operating income for the year ended December 31, 2015 compared to the year ended December 31, 2014, principally due to the recognition of an impairment on the investment in the Barranca Larga—Ventanilla highway concession in the amount of Ps. 2,209 million. Cost overruns stemming from social and environmental issues as well as updated estimated traffic studies have caused the project to be financially unviable; accordingly, most of the construction on the project has been suspended. Currently, we are analyzing different alternatives to generate financial viability for the project. Additionally, the account receivable for the Rio de los Remedios—Ecatepec projects was impaired by Ps. 1,021 million pursuant to a change of estimated profitability. Please see “Item 4. Information on The Company – B. Business Overview – Description of Business Segments – Concessions.”

62

The Concessions segment reported a 5% increase in operating income for the year ended December 31, 2014 compared to the year ended December 31, 2013, principally due to an increase in segment revenues related to finance, construction and operation in certain highways discussed above, as well as a decrease in general expenses margins primarily to decreased administrative cost partially offset by an increase in costs principally related to subcontractors and suppliers. The changes described above are related primarily to increases in operating income from the Rio Verde Ciudad Valles Highway, the La Piedad bypass and the new branch of the Kantunil-Cancun toll road, due to the fact that these concessions commenced operations in the fourth quarter of 2013.

Airports

The following table sets forth the revenues and operating results of our Airports segment for each year in the three-year period ended December 31, 2015.

	Year Ended December 31,
	2015			2014			2013
	(Millions of Mexican pesos)
Revenues		Ps. 4,477			Ps. 3,770			Ps. 3,420
Operating income		1,915			1,516			1,145
Operating margin		43	%		40	%		33	%

Revenues.

The Airports segment’s revenues increased by 19% in the year ended December 31, 2015 from the year ended December 31, 2014, primarily as a result of an increase in both aeronautical and non-aeronautical revenues. The sum of aeronautical and non-aeronautical revenues in the year ended December 31, 2015 increased by 21.1% as compared to the year ended December 31, 2014.

Aeronautical revenues increased by 19.8% in the year ended December 31, 2015 from the year ended December 31, 2014, primarily due to an increase in passenger charges from Ps. 2,068 million in the year ended December 31, 2014 to Ps. 2,533 million in the year ended December 31, 2015. This increase in passenger charges was attributable to a 15.2% increase in passenger traffic from 14.7 million in 2014 to 16.9 million in the year ended December 31, 2015.

Non-aeronautical revenues increased by 24.9% from Ps. 890 million in the year ended December 31, 2014 to Ps. 1,111 million in the year ended December 31, 2015, due primarily to car parking revenues, which increased by 24.3% from Ps. 146 million in the year ended December 31, 2014 to Ps. 181 million in 2015, OMA Carga operations, which increased by 127.1% from Ps. 47 million in the year ended December 31, 2014 to Ps. 107 million in 2015, baggage screening revenues, which increased by 26.4% from Ps. 79 million in 2014 to Ps. 100 million in the year ended December 31, 2015, food and beverage revenues, which increased by 24.7% from Ps. 54 million in the year ended December 31, 2014 to Ps. 67 million in the year ended December 31, 2015, and advertising revenues, which increased by 11.3% from Ps. 87,420 in the year ended December 31, 2014 to Ps. 97,255 in the year ended December 31, 2015.

Total terminal passenger traffic volume increased 15.2% in the year ended December 31, 2015 compared to the year ended December 31, 2014. Domestic terminal passenger traffic volume increased 14.6%, while international terminal passenger traffic volume increased 16.5%. The main percentage increases in total terminal passenger traffic volume (excluding transit passengers) in the year ended December 31, 2015 as compared to the year ended December 31, 2014 were at the Torreon (with a 45.8% increase), Durango (with a 23.4% increase), San Luis Potosi (with an 18.9% increase) and Monterrey (with an 18.7% increase) airports, while the Monterrey airport had the greatest absolute increase in total terminal passenger traffic volume.

The Airports segment’s revenues increased by 10% in the year ended December 31, 2014 from the year ended December 31, 2013, primarily as a result of increase in revenue from an increase in both aeronautical and non-aeronautical revenues. The sum of aeronautical and non-aeronautical revenues in the year ended December 31, 2014 increased by 12% as compared to the year ended December 31, 2013.

63

Aeronautical revenues increased by 12% in the year ended December 31, 2014 from the year ended December 31, 2013, primarily due to an increase in passenger charges from Ps. 1,854 million in the year ended December 31, 2013 to Ps. 2,068 million in the year ended December 31, 2014. This increase in passenger charges was attributable to a 11% increase in passenger traffic from 13.3 million in 2013 to 14.7 million in the year ended December 31, 2014.

Non-aeronautical revenues increased by 12% in the year ended December 31, 2014 from the year ended December 31, 2013, primarily due to car parking revenues, which increased 14% from Ps. 128 million in the year ended December 31, 2013 to Ps. 146 million in 2014, hotel services revenues, which increased 11% from Ps. 177 million in the year ended December 31, 2013 to Ps. 196 million in the year ended December 31, 2014, baggage-screening revenues, which increased 23% from Ps. 64 million in the year ended December 31, 2013 to Ps. 79 million in the year ended December 31, 2014, food and beverage revenues, which increased 16% from Ps. 46 million in the year ended December 31, 2013 to Ps. 54 million in the year ended December 31, 2014, and advertising revenues, which increased 9% from Ps. 80 million in the year ended December 31, 2013 to Ps. 87 million in the year ended December 31, 2014.

Total terminal passenger traffic volume increased 10.6% in the year ended December 31, 2014 compared to 2013. Domestic terminal passenger traffic volume increased 10.8%, while international terminal passenger traffic volume increased 9%. The main percentage increases in total terminal passenger traffic volume (excluding transit passengers) in the year ended December 31, 2014 as compared to the year ended December 31, 2013 were at the San Luis Potosi (with a 43% increase), Reynosa (with a 20% increase), Tampico (with a 13% increase) and Torreon (with a 12% increase) airports, while the Monterrey airport had the greatest absolute increase in total terminal passenger traffic volume.

Operating Income. The Airports segment reported a 26% increase in operating income for the year ended December 31, 2015 compared to the year ended December 31, 2014, mainly as a result of the increase in total revenues.

The Airports segment reported a 32% increase in operating income for the year ended December 31, 2014 compared to the year ended December 31, 2013, mainly as a result of the increase in total revenues.

Industrial Construction

The Industrial Construction segment is comprised of our 50% equity interest in ICA Fluor. The results of the Industrial Construction segment are reflected in joint ventures and associated companies. See “Item 5. Operating and Financial Review and Prospects—Operating Results—Share in Results of Joint Ventures and Associated Companies.”

Corporate and Other

The Corporate and Other segment includes our housing inventories, including our horizontal housing assets, which, due to their relative size, are no longer presented as a stand-alone segment. The segment also includes the administrative operations of our holding and subholding companies, including functions that are not directly managed by our other business segments. The following table sets forth the revenues and operating income of the Corporate and Other segment for each year in the three-year period ended December 31, 2015.

	Year Ended December 31,
	2015			2014			2013
	(Millions of Mexican pesos)
Revenues		Ps. 653			Ps. 1,457			Ps. 872
Operating loss		(1,133	)		(341	)		(291	)
% Margin		(173	)%		(23	)%		(33	)%

64

Revenues. The Corporate and Other segment’s revenues decreased by 55% in the year ended December 31, 2015 from the year ended December 31, 2014, principally due to the divestments of real estate we have undertaken, such as the sale of our Grupo Punto Condesa for proceeds in the amount of Ps. 500 millon, as part of a short-term strategy to focus on our operations in the construction segment and pay down certain indebtedness The Corporate and Other segment’s revenues increased by 67% in the year ended December 31, 2014 from the year ended December 31, 2013, principally due to an increase in real estate and property sales principally related to reactivation in our low income housing developments as well as continued real estate divestment.

Operating Loss. The Corporate and Other segment’s operating loss increased to a loss of Ps. (1,133) million in the year ended December 31, 2015 as compared to a loss of Ps. (341) million in the year ended December 31, 2014, which is mainly due to the recognition of a reduction in value in the real estate inventory and assets available for sale of Ps. 1,030 million, taking into account the sales forecasts, the current economic environment, the current business plan, and the restructuring plan in process.

The Corporate and Other segment’s operating loss increased to Ps. 341 million in the year ended December 31, 2014 from a loss of Ps. 291 million in the year ended December 31, 2013, which is due to the recognition of an impairment of certain real estate inventories for Ps.114 million.

Backlog

The following table sets forth, at the dates indicated, our backlog of Civil Construction, mining services and other services contracts, which are consolidated (San Martin mining services and construction contracts through September 2015), and joint venture and associated company contracts, which are unconsolidated (and include San Marting mining services and construction contracts beginning in September 2015). Our distressed financial capacity may adversely affect our ability to win awards. The amounts included in the table below for joint venture and associated company backlog represent the full amounts of the related contracts.

	As of December 31,
	2015		2015		2014		2013
	(Millions of U.S. dollars)		(Millions of Mexican pesos)
Civil Construction Backlog	U.S.$	1,867		Ps. 32,380		Ps. 36,957		Ps. 30,658
Mining Services Backlog		—		—		4,770		4,949
Other Services Backlog		5		91		337		751
Joint Venture and Associated Company Backlog		1,855		32,163		21,230		10,864

Civil Construction Backlog

Total Civil Construction segment backlog at December 31, 2015 decreased 12% compared to December 31, 2014, reaching Ps. 32,380 million primarily due to the increase in the execution of works of certain projects, mainly concession projects such as the Palmillas - Apaseo El Grande Highway and the Mitla - Tehuantepec Highway, reductions related to certain projects such as the Barranca Larga Ventanilla Highway and to a lesser extent, the deconsolidation of San Martin in Peru.

Total Civil Construction segment backlog at December 31, 2014 increased 21% compared to December 31, 2013, reaching Ps. 36,957 million primarily due to the incorporation of Ps. 3,299 million (U.S.$224 million) in backlog of the Facchina construction projects at December 31, 2014, which represents 52% of the increase in this backlog.

65

The table below sets forth the nine projects that represented approximately 87% of backlog in the Civil Construction segment as of December 31, 2015.

	Amount		Estimated Completion Date	% of Civil  Construction Backlog
	(Millions of Mexican pesos)
Civil Construction Backlog
Monterrey Aqueduct VI		4,688	36 months after commencement of construction		14	%
Santa Maria Dam		4,125	Third quarter of 2018		13	%
Facchina		3,612	-		11	%
Palmillas – Apaseo El Grande Toll Road		3,398	Fourth quarter of 2016		10	%
Mitla-Tehuantepec Highway		Ps. 2,822	Fourth quarter of 2016		9	%
Mexico – Toluca train		2,397	Fourth quarter of 2017		7	%
Churubusco – Xochiaca Tunnel		2,219	Fourth quarter of 2017		7	%
Eastern Discharge Tunnel		2,196	Fourth quarter of 2018		7	%
Sonora State Package Highways		1,392	Second quarter of 2019		4	%
Guatemala penitentiary		1,226	Second quarter of 2016		4	%

As of December 31, 2015 approximately 16% of Civil Construction segment backlog was attributable to construction projects outside Mexico, and public sector projects represented approximately 81% of our total Civil Construction backlog.

Our book and burn index (defined as the ratio of new Civil Construction contracts, plus net Civil Construction contract additions to existing contracts, to executed Civil Construction works) was 0.7 in 2015 compared to 1.4 in 2014. New contract awards and net increases to existing contracts during 2015 were lower than the execution of projects during the year.

Mining and Other Services Backlog

As a result of the deconsolidation of San Martin, as of December 31, 2015, our mining backlog is no longer presented in our consolidated backlog. However, it is presented as part of the backlog of Associated and Joint Venture companies. The other services contracts correspond to contracts for machinery and equipment leasing of Ps. 91 million, as compared to Ps. 337 million in 2014.

Total mining services and other backlog at December 31, 2014 decreased compared to December 31, 2013, primarily due to the fact that the rate of completion of projects was higher than the rate of our acquisition of new contracts.

Joint Venture and Associated Company Backlog

Our joint venture and associated company backlog at December 31, 2015 increased compared to December 31, 2014, reaching Ps. 32,163 million at December 31, 2015, from Ps. 21,230 million at December 31, 2014, primarily due to the incorporation of San Martin’s backlog, our associated entity in Peru, both for its construction contracts such as mining, as well as the addition of the new contract 4A package in Tula from ICA Fluor for Ps. 18,932 million.

Our total joint venture and associated company backlog at December 31, 2014 increased compared to December 2013, reaching Ps. 21,230 million, primarily due to the new contracts of ICA Fluor such as the Tula Refinery Phase II of Ps. 18,339 million, the Ramones II Sur Gas Pipeline of Ps. 9,379 million and the well pad modules for Shell Canada of Ps. 3,549 million as well as net contract additions.

Financing Cost, Net

The following table sets forth the components of our net financing costs for each year in the three-year period ended December 31, 2015.

	Year Ended December 31,
	2015			2014			2013
	(Millions of Mexican pesos)
Interest expense		Ps. 6,840			Ps. 6,170			Ps. 4,102
Interest income		(327	)		(481	)		(500	)
Exchange (gain) loss, net		4,740			3,161			357
Loss (gain) on financial instruments		(287	)		580			326
Financing cost, net(1)		Ps. 10,966			Ps. 9,430			Ps. 4,285

(1) Does not include net financing costs of Ps. 688 million, Ps. 692 million and Ps. 616 million in 2015, 2014 and 2013, respectively, that are included in cost of sales. See Note 37 to our consolidated financial statements.

Net financing costs in the year ended December 31, 2015 reached Ps. 10,966 million. The 16% increase in net financing costs in the year ended December 31, 2015 from the year ended December 31, 2014 was mainly due to exchange losses from the depreciation of the Mexican Peso against the U.S. dollar, and increased interest expenses as a result of the depreciation of the Mexican Peso against the U.S. Dollar, which were partially offset by gains in the valuation of financial instruments.

Net financing costs in 2014 reached Ps. 8,454 million. The 150% increase in net financing costs in the year ended December 31, 2014 from the year ended December 31, 2013 was mainly due to exchange losses from the depreciation of the Mexican peso against the U.S. dollar; interest expense as a result of the early amortization of capitalized costs for the prepayment of U.S. $200 million of our 2017 notes, and from the effect of the calculation of the net present value of the liability resulting from the fiscal deconsolidation that occurred in 2013 as a result of changes in the tax consolidation regime.

Interest expense increased by 11% in the year ended December 31, 2015 compared to the year ended December 31, 2014, primarily due to the depreciation of the mexican peso against the U.S. dollar, as interest on our bonds are denominated in dollars.

Interest expense increased by 50% in the year ended December 31, 2014 compared to the year ended December 31, 2013, primarily due to the accelerated amortization of placement expenses on our repurchased notes, the prepayment premium offered to holders, commissions, and the early amortization of the capitalized costs; the effect of the calculation of the net present value of the liability resulting from the fiscal deconsolidation that occurred in 2013 as result of changes in the tax consolidation regime; and the cost of early termination of derivatives related to the La Piedad Bypass and the Rio Verde – Ciudad Valles highway project financings.

Interest income decreased by 32% in the year ended December 31, 2015 in part due to a decrease in excess cash held for operation.

Interest income decreased by 4% in the year ended December 31, 2014 in part due a decrease of excess cash held for the operation which is partially offset partly by variations in bank interest rates.

Our total debt as of December 31, 2015 increased 7% compared to December 31, 2014, primarily as result of the depreciation of the Mexican peso against the U.S. dollar, and increased borrowing in our Concessions segment.

Our total debt as of December 31, 2014 increased 39% compared to December 31, 2013, primarily as result of the depreciation of the Mexican peso against the dollar, and increased borrowing in our Concessions, Airports and Corporate and Other segments.

67

At December 31, 2015 and March 31, 2016 we had U.S.$ 32,140 million and U.S.$ 27,341 million, respectively, of debt issued or guaranteed as joint obligor or guarantor by our parent company.

At December 31, 2014 and March 31, 2015, we had U.S.$3,285 million and U.S.$3,336 million, respectively, of debt issued or guaranteed as joint obligor or guarantor by our parent company.

At December 31, 2015, 2014 and 2013, 45%, 45% and 35% respectively, of our total debt was denominated in currencies other than Mexican pesos, principally U.S. dollars. We may in the future incur additional non-peso denominated indebtedness. Declines in the value of the Mexican peso relative to such other currencies could both increase our interest costs and result in foreign exchange losses. Conversely, an increase in the value of the Mexican peso relative to such other currencies could have the opposite effect.

Share in Results of Joint Ventures and Associated Companies

Our share in joint ventures and associated companies includes the operations ICA Fluor; our environmental services affiliate PMA Mexico (sold in December 2015), which operates municipal potable water treatment and supply, sewage, waste water treatment and other waste management systems; our real estate affiliate Los Portales S.A.; our affiliate Actica San Martin (starting in October 2015), and the Facchina joint ventures, among others. Our Industrial Construction segment, comprised of the ICA Fluor joint venture, accounted for 74%, 41% and 62% of our total share in results of joint ventures and associated companies as of December 31, 2015, 2014 and 2013, respectively.

The following table sets forth our share in results of unconsolidated joint ventures and associated companies by segment for each year in the three-year period ended December 31, 2015.

	Year Ended December 31,
	2015		2014			2013
	(Millions of Mexican pesos)
Civil Construction		Ps. 137		Ps. 94			Ps. 180
Industrial Construction		44		(3	)		67
Concessions		284		123			21
Corporate and Other		356		335			103
Total		Ps. 821		Ps. 549			Ps. 350

We include the results of our investments in the following associated companies and joint ventures in our Civil Construction segment: Grupo Rodio Kronsa (sold in the fourth quarter of 2015), Constructoras de Infraestructura de Agua del Potosí, Infraestructura y Saneamiento Atotonilco, Aquos El Realito, Administracíon y Servicios, the Atotonilco water treatment plant, the Acapulco Scenic Bypass, three of the Facchina’s joint venture projects, the Consortium for maintenance of oil pipelines in southern Colombia and the Construction Consortium for Line 3 of the metro in Chile, and beginning in the fourth quarter of 2015, the San Martin investment.

We include our share of the results of the following associated companies and alliances in the Concessions segment: PMA Mexico (sold in the fourth quarter of 2015), Autovia Nuevo Necaxa – Tihuatlan, Autovia Mitla – Tehuantepec, Renova – Atlatec, Suministro de Agua de Queretaro and El Realito.

We include the results of our investments in the following companies in the Corporate and Other segment: Los Portales, Fideicomiso Banco Invex, S.A. Reserva Escondida Trust (sold in the fourth quarter of 2015) Trust and Actica.

We include the results of our investment in ICA Fluor in the Industrial Construction segment.

Our share of income of unconsolidated associated companies represented a gain of Ps. 821 million in the year ended December 31, 2015 as compared to Ps. 549 million in the year ended December 31, 2014, primarily due to an increase in net income from ICA Fluor, PMA Los Portales y Autovia Mitla – Tehuantepec, among others. Our share of income of unconsolidated associated companies represented a gain of Ps. 549 million in the year ended December 31, 2014 as compared to Ps. 350 million in the year ended December 31, 2013, primarily due to the addition of Ps. 78 million in joint venture projects of Facchina, as well as an increase in net income from PMA Mexico and SAQSA.

68

With regard to ICA Fluor in particular, our share in results of our investment in ICA Fluor increased 173% in the year ended in December 31, 2015 from a loss in the year ended December 31, 2014 and increased 27.4% in the year ended December 31, 2014 from the year ended December 31, 2013. ICA Fluor’s revenues increased 95% in the year ended December 31, 2015 from the year ended December 31, 2014 principally due to the high volume of activity in Tula Coker plant and Los Ramones Sur gas pipeline projects. ICA Fluor’s revenues increased by 21% in the year ended December 31, 2014 from the year ended December 31, 2013 principally due to the high volume of activity in the Los Ramones Sur gas pipeline project, which had total revenues of Ps. 2,699 million during the year ended December 31, 2014, partially offset by the lower margins in this project. ICA Fluor’s operating income increased by 171% in the year ended December 31, 2015 from the year ended December 31, 2014, principally due to maintaining administrative costs at levels similar to the year ended December 31, 2014, coupled with a significant increase in revenue. ICA Fluor’s operating income increased by 99% in the year ended December 31, 2014 from the year ended December 31, 2013, principally due to maintaining administrative costs at levels similar to the year ended December 31, 2013, in addition to a significant increase in revenue.

Tax

In December 2013, the Mexican Congress approved a tax reform that became effective on January 1, 2014. The previous fiscal consolidation regime, which had permitted a parent company to report taxes on a consolidated basis, including those of majority-owned subsidiaries, was eliminated. Additionally, the tax reform eliminated the IETU regime and planned reductions in the statutory income tax rate were eliminated, such that the tax rate will continue at 30%.

In 2014, a new optional tax regime (the “Optional Regime for Groups of Companies”) was approved for companies that meet conditions and requirements similar to the previous regime of consolidation. This new optional tax regime allows qualifying companies , under certain rules, to defer a portion of income tax for up to three years through the determination of an integration factor, which is applied individually by all companies in the group to determine the income tax payable.

We chose to join the new Optional Regime for Groups of Companies of 2014, as allowed by the Income Tax Law of 2014, after submitting to the tax authorities the corresponding notice. We opted in this regime to take advantage of the minimum deferral available for the current fiscal year and potential deferrals in the future.

Tax liabilities due to the effects of deconsolidation as of December 31, 2013 will continue to be paid under the terms of the previous tax law. As of December 31, 2015 our estimated total liability for tax deconsolidation was Ps. 3,845 million, of which amount we have recorded Ps. 1,228 million as short-term and Ps. 2,617 million as a long-term liability (net of discounting for present value). As of December 31, 2014, we recorded Ps. 3,881 million of tax liability from deconsolidation, of which Ps. 182 million were recorded as short-term and Ps. 3,699 million were recorded as a long-term liability. See Note 28 to our consolidated financial statements.

As a result of the repeal of the IETU, the deferred IETU tax liability that we had recognized of Ps. 512 million in 2013 was cancelled for accounting purposes as of the date of the promulgation of the tax reform. See Note 28 to our consolidated financial statements.

In 2015, we recorded consolidated net tax of Ps. 3,223 million. As of December 31, 2015, we recorded a deferred income tax asset of Ps.3,333 million, comprised of temporary differences of Ps.3,331 million (including a benefit from deductible temporary differences on items included in other comprehensive income for Ps.161 million) and IMPAC recoverable of Ps.2 million. Additionally, we recorded a net deferred ISR liability of Ps.2,866 million, comprised mainly of Ps.2,694 million of taxable temporary differences and Ps.172 million of taxable temporary differences on items included in other comprehensive income. Our effective tax rate was (19.49%) in 2015. The 45.96% increase over 2014 was due primarily to deferred tax assets not recognized in 2014 of Ps. 7,288 million (44.06%). The effective tax rate differed from the statutory rate in 2015 by 49.49% due to the net effect of inflation, non-deductible expenses, tax losses updated with the inflation, investment in concessions, deferred tax assets not recognized previously and the effects of the difference in rates of foreign subsidiaries.

69

In 2014, we recorded consolidated net tax benefits of Ps. 751 million, which included income tax benefits of Ps. 1,034 million and tax credits for foreign taxes paid of Ps. 2 million. As of December 31, 2014, we recorded a deferred income tax asset of Ps. 6,164 million, comprised of temporary differences of Ps.6,106 million (including a benefit from deductible temporary differences on items included in other comprehensive income for Ps. 30 million), Ps. 55 million related to tax credits for foreign taxes paid and IMPAC recoverable of Ps. 2 million. Additionally, we recorded a net deferred income tax liability of Ps. 2,616 million, comprised mainly of Ps. 2,601 of taxable temporary differences and Ps. 15 million of taxable temporary differences on items included in other comprehensive income. Our effective tax rate was 26.47% in 2014. The 6.71% increase over 2013 was due primarily to the cancellation in 2013 of Ps. 512 million of deferred IETU tax liability (74.45%), the recovery of Ps. 125 million in taxes on assets (14.75%) (Asset Tax, or IMPAC) in 2013, due to the net effect of inflation Ps. 231 million (21.72%) and the effects of the difference in rates of foreign subsidiaries Ps. 191 million (17.88%). The effective tax rate differed from the statutory rate in 2014 by 3.53% due to the net effect of inflation, non-deductible expenses, the effects of unrecognized tax benefits, investments in joint ventures and associated companies and the effects of the difference in rates of foreign subsidiaries.

In 2013, we recorded consolidated net tax benefits of Ps. 354 million, which included income tax of Ps. 137 million and IETU benefits of Ps. 491 million. As of December 31, 2013, we recorded a deferred income tax asset of Ps. 4,546 million comprised of net deductible temporary differences of Ps. 4,199 million, Ps. 250 million related to tax credits for foreign taxes paid and IMPAC recoverable of Ps. 97 million. Additionally, we recorded a net deferred ISR liability of Ps. 2,075 million mainly of Ps. 2,126 of taxable temporary differences and Ps. 51 million of benefit of taxable temporary difference on items included in other comprehensive income. Our effective tax rate was (33.18)% in 2013. The (29.43)% increase over 2012 was due primarily due to of Ps. 703 million the effects of the difference in rates of subsidiaries (75.75%), due to the net effect of inflation of Ps. 513million (55.30%) and IETU tax liability of Ps. 89 million (9.55%).

The statutory tax rate in Mexico is 30%. Generally, the differences between effective tax rates and statutory tax rates are due to different rates for foreign subsidiaries, the effects of inflation and exchange rate fluctuations.

As of December 31, 2015, we assessed the probability for recovery of tax loss carry forwards, and decided to exclude from the determination of deferred taxes an amount of Ps.19,166 million. Until December 31, 2014 such tax losses were included in this determination, this led to the cancellation of Ps.5,750 million of deferred income tax assets in conjunction with our restructuring analysis. However, we maintain our right to redeem this tax loss, which has a term ranging between 6 and 10 years. See Note 28 to our financial statements.

Additionally we have been working with the Mexican tax authority to resolve any payments delays through in-kind payments or otherwise. See Note 22 (4) to our consolidated financial statements

As of December 31, 2015, the outstanding tax payment amounts is Ps. 973 million.

Net Income

We reported a consolidated net loss of Ps.(19,764) million in the year ended December 31, 2015, compared to consolidated net loss of Ps.(2,086) million in the year ended December 31, 2014, representing an increase in net loss of 848%.

We reported a consolidated net loss of Ps. 2,086 million in the year ended December 31, 2014, compared to consolidated net income of Ps. 1,422 million in the year ended December 31, 2013, representing a decrease of 247%.

Net income of non-controlling interest was Ps. 659 million in the year ended December 31, 2015 and Ps. 937 million in the year ended December 31, 2014. Net loss of controlling interest was Ps.(20,423) million in the year ended December 31, 2015 and net income of controlling interest was Ps. 3,024 million in the year ended December 31, 2015.

70

Net income of non-controlling interest was Ps. 937 million in the year ended December 31, 2014 and Ps. 999 million in the year ended December 31, 2013. Net loss of controlling interest was Ps. 3,024 million in the year ended December 31, 2014 and net income of controlling interest was Ps. 424 million in the year ended December 31, 2013.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in accordance with IFRS, including its amendments and interpretations, as issued by IASB.

Below is a description of the principal critical accounting policies which require the significant use of estimates and the judgment of management based on their experience and current events, as well as a description of the respective accounting internal control.

Accounting for Construction Contracts

Accounting Policy

Revenue is recognized to the extent that it is probable that the economic benefits associated with the transaction will flow to the company. Revenue is measured at the fair value of the consideration received or receivable and represents the amounts receivable for goods and services provided in the normal course of activities. Revenues are reduced for estimated customer returns, rebates and other similar allowances.

For accounting purposes, we recognize revenue from construction contracts using the percentage of completion method, based on the cost incurred method, taking into account the development of activities considering total costs and revenues estimated at the end of the project, established in International Accounting Standard 11 “Construction Contracts” (“IAS 11”). The percentage of completion method provides an understanding of the performance of the project in a timely manner, and appropriately presents the legal and economic substance of the contracts. Under this method, revenue from the contract is compared against the costs incurred by the contract, based on percentage-of-completion, which determines the amount of revenue, expenses and income that can be attributed to the portion of work completed.

The base revenue utilized to calculate percentage of profit includes the following: (i) the initial amount established in the contract, (ii) additional work orders requested by the customer, (iii) changes in the considered yields, (iv) the value of any adjustments (for inflation, exchange rates or changes in prices, for example) agreed to in the contract, (v) the decrease in the original contract value and agreements in contracts (vi) claims and conventional penalties, and (vii) completion or performance bonuses, as of the date on which any revision takes place and is effectively approved by the customers.

In order to determine the basis for costs used to calculate the percentage of completion in accordance with the costs incurred method, we consider the following: (i) the costs directly related to the specific contract, (ii) indirect costs related to the general contract activity that can be identified with a specific contract; and (iii) any other costs that may be transferred to the customer under the contract terms. The costs directly related to the specific contract include all direct costs such as materials, labor, subcontracting costs, manufacturing and supply costs of equipment carried out in independent workshops, start-up costs and depreciation. Indirect costs identified that are assignable to the contract include indirect labor, payroll of technical and administrative personnel, construction site camps and related expenses, quality control and inspection, internal and external contract supervision, insurance costs, bonds, depreciation, amortization, repairs and maintenance.

Costs which are not included within contract costs are: (i) any general administrative expenses not included under any form of reimbursement in the contract; (ii) selling expenses; (iii) any research and development costs and expenses not considered reimbursable under the contract; and (iv) the depreciation of machinery and equipment not used in the specific contract even though it is available on hand for a specific contract, when the contract does not allow revenue for such item. In addition, work performed in independent workshops and construction in-process are also excluded and are recorded as assets when they are received or used under a specific project.

71

Variations in the scope of construction works may arise due to several factors, including: improvements in the construction process due to reduced supplies or runtime, local regulatory changes and changes in the conditions for the execution of the project or its implementation, design changes requested by the customer and the geological conditions not included in the original plan. Additionally, and in order to identify possible changes in contracts, we have implemented a method whereby these changes can be identified and reported, and whereby the amounts can be quantified and approved and the changes implemented efficiently on projects. A variation in contract revenue is recognized when (a) it is probable that the changes will be approved and the amount of revenue resulting from the change, (b) the amount of revenue can be reliably measured and (c) and it is probable that the economic benefits flow to the entity. Claims or incentives for early completion are recognized as part of the revenue of a contract, provided that there is sufficient evidence that the customer will authorize payment for these items. Consequently, claims and incentives are included in contract revenue only when (a) negotiations have reached an advanced stage such that it is probable that the customer will accept the claim, and (b) the probable amount to be accepted by the customer can be reliably determined. With respect to incentive payments, revenues are recognized only when the execution of the contract is significantly advanced to conclude that the specified standards of performance will be achieved or exceeded and the amount of the incentive payment can be reliably measured.

Costs incurred for change orders based on customers’ instructions which are still awaiting definition and price authorization are recognized as assets within the caption “cost and estimated earnings in excess of billings on uncompleted contracts.”

For those funded projects in which financing revenue are included as part of the selling price, only borrowing costs directly related to the acquisition or construction of the asset, less the realized yields by the temporary investment of such funds and the exchange loss, to the extent it is an adjustment to interest costs, are attributed to the contract costs. The borrowing costs that exceed the estimates and cannot be passed on to the customers are not part of contract costs. In these types of contracts, the collection of the contract amount from the client may take place at the completion of the project. However, periodic reports of the advance of the project to date are provided to and approved by the client, which serve as the basis so that we can continue to obtain financing for the project.

When a contract includes construction of various facilities, construction of each facility is treated as a separate profit center when: (i) separate proposals have been submitted for each facility; (ii) each facility has been subject to separate negotiation and we and the customer have been able to accept or reject that part of the contract relating to each asset; (iii) the costs, revenues and profit margin of each asset can be identified.

A group of contracts, whether with one or several clients, are treated together as one unique center of profit when: (i) the group of contracts have been negotiated together as a unique package; (ii) the contracts are so closely interrelated that they are effectively part of a single project with an overall profit margin; and (iii) the contracts are executed simultaneously or in a continuous sequence.

The estimated profit of various profit centers cannot offset one another. We ensure that when several contracts integrate a profit center, its results are properly combined.

Under the terms of various contracts, revenue recognized is not necessarily related to the amounts billable to customers.

The line item “Cost and Estimated Earnings in Excess of Billings on Uncompleted Contracts” included in the heading of “Customers”, originates from construction contracts and represents the difference between the costs incurred plus recognized profit (or less any recognized losses) and less certifications made for all contracts in progress, in excess of the amount of the certificates of work performed and invoiced. Any amounts received before work has been performed are included in the consolidated statement of financial position as a liability, as advances from customers. Amounts invoiced from the performed work but not yet paid by the customer are included in the consolidated statement of financial position as billing contracts and other receivables.

72

Internal Control

As part of the planning process of a construction contract before commencing any project, we review the principal obligations and conditions of the specific contract for the purpose of reasonably estimating (i) the projected revenue, (ii) the costs to be incurred in the project, (iii) the gross profit of the project. We determine the method by which to accurately measure the executed work based on this review, and in conjunction with an analysis, based on each contract, of the legal and economic rights for the receipt of payment for the work performed.

The decision of whether or not to participate in a project is made collectively with representatives of the technical, legal, financial and administrative areas, which considers an analysis of the customer’s economic solvency and reputational standing, the legal framework, the availability of resources, the technological complexity of the project, the obligations and rights assumed, the economic, financial and geological risks, and the possibility of mitigation of risks, as well as the analysis of each contract. Our policy is to avoid contracts with material risks, unless such risks may be mitigated or transferred to the customers, suppliers and/or subcontractors.

In contracts involving performance guarantees related to the equipment on which the performance of the project depends, the decision to participate will depend on, among other factors, our ability to transfer the risks and penalties related to these guarantees to the suppliers and/or subcontractors.

In contracts involving guarantees related to timely delivery, we generally plan the project to take into consideration the risk of delay and allow sufficient time for the timely completion of the project in spite of unavoidable delays.

Projects are executed in accordance with a work program determined prior to commencement of the project, which is periodically updated. The work plan includes the description of the construction to be performed, the critical execution route, the allocation and timeliness of the resources required and the project’s cash flow forecast.

The construction contracts into which we enter are generally either (i) unit price or (ii) fixed price (either lump sum or not-to exceed). The evaluation of the risks related to inflation, exchange rates and price increases for each type of contract depends on if the contract is a public works contract or is with the private sector.

In unit price contracts in the private sector, the customer generally assumes the risks of inflation, exchange-rate and price increases for the materials used in the contracts. Under a unit price contract, once the contract is signed the parties agree upon the price for each unit of work. However, unit price contracts normally include escalation clauses whereby we retain the right to increase the unit price of such inputs as a result of inflation, exchange-rate variations or price increases for the materials, if any of these risks increases beyond a percentage specified in the contract.

For unit price contracts related to public works, in addition to escalation clauses, in Mexico the “Public Works and Services Law” establishes mechanisms to adjust the value of such public unit-price contracts for cost increases. The Public Works and Services Law provides the following mechanisms for the adjustment of unit prices in unit-price contracts: (i) a review of individual unit prices for which adjustment may be possible; (ii) review of unit prices by group where the estimated amount of work remaining to be performed represents at least 80% of the total amount of remaining work under the contract; and (iii) for those projects in which the relationship between the input and the total contract cost is established, an adjustment to reflect the increased cost may be made based on such proportion. The application of these mechanisms is required to be specified in the relevant contract.

In lump sum contracts, not-to-exceed contracts or contracts where there are no escalation clauses in which we undertake to provide materials or services at fixed unit prices required for a project in the private sector, we generally absorb the risk related to inflation, exchange-rate fluctuations or price increases for materials. However, we seek to mitigate these risks as follows: (i) when the bid tender is prepared, such risks are included in determining the costs of the project based on the application of certain economic variables which are provided by recognized economic analysis firms; (ii) contractual arrangements are made with the principal suppliers, among which advance payments are made to ensure that the cost of the materials remains the same during the contract term; and (iii) the exchange-rate risk is mitigated by contracting suppliers and subcontractors in the same currency as that in which the contract is executed with the customer.

73

For those risks that cannot be mitigated or which surpass acceptable levels, we carry out a quantitative analysis in which we determine the probability of occurrence of the risk, measure the potential financial impact, and adjust the fixed price of the contract to an appropriate level.

For fixed price contracts in the public sector, the Public Works and Services Law protects the contractors when adverse economic conditions arise that could not have been anticipated at the time of awarding the contract and thus were not considered in the initial contract bid. The Public Works and Services Law allows the Controller’s Office (Secretaria de la Funcion Publica) to issue guidelines through which public works contractors may recognize increases in their initial contract prices as a result of adverse economic changes.

In recent years, our construction contracts have been increasingly of the fixed price type or mixed price contracts in which a portion of the contract is at fixed price and the rest at unit prices. While we have entered into contracts with unit pricing in the last three years, we believe that fixed price contracts are more prevalent in the construction market and the contracts that we enter into in the future will reflect this shift to fixed price contracts.

Furthermore, we expect that due to the financing trends, future contracts related to concessions, infrastructure construction and industrial construction will restrict adjustments to the contract price for additional work performed as a result of incorrect contract specifications.

In order to be able to apply percentage-of-completion method, the following requirements must be met: (i) the contract must clearly specify the legal rights related to the goods or services to be provided and to be received by the parties, the consideration to be exchanged and the terms of the agreement; (ii) our legal and economic right to receive the payment for the work performed as the contract is executed must be specified; (iii) the expectation must be that both the contractor and the customer will fulfill their respective contractual obligations; and (iv) based on the construction budget and contract, the total amount of revenue, the total cost to be incurred and the estimated profit can be determined.

The estimations are based on the terms, conditions and specifications of each specific contract, including assumptions made by management of the project in order to ensure that all costs attributable to the project were included.

Periodically, we evaluate the reasonableness of the estimates used in the determination of the percentage of completion. Cost estimates are based on assumptions, which can differ from the actual cost over the life of the project. Accordingly, estimates are reviewed periodically, taking into account factors such as price increases for materials, the amount of work to be done, inflation, exchange-rate fluctuations, changes in contract specifications due to adverse conditions and provisions created based on the construction contracts over the project duration, including those related to penalties, termination and startup clauses of the projects and the rejection of costs by customers, among others. If, as a result of this evaluation, there are modifications to the revenue or cost previously estimated, adjustments are made for the percentage of completion and if there are indications that the total estimated cost of the project exceeds expected revenues, a provision is recognized for estimated contract loss in the period in which it is determined. The estimated revenues and estimated costs may be affected by future events. Any change in these estimates may affect our results.

In addition to our technical and operational processes, our construction operations include legal and economic factors that help us to determine the probability that economic benefits will flow to us from claims and work executed:

• Construction contracts in which we participate are typically governed by the civil law of various jurisdictions that recognize a contractor’s right to receive payment for work performed. The buyer is the legal owner of the works in execution while they are in-process, and the contractor (ICA) is entitled to payment for work performed, even though payment may not occur until the completion of the contract. The typical terms of our contracts also provide for our right to receive payment for work performed.

74

We also have established procedures that support the requirements of work performed for our customers, such as the work log, authorizations of the physical progress by the supervisor of the customer, construction contracts and their addendums and/or amendments. The reconciliation and recognition of the work performed and the definition of prices are slower.

• A significant portion of our contracts entered into with the public sector are with the state governments or government offices, which have a slower process of authorization of work performed, due to the fact that a change in the elected federal government also may cause changes in the administrations of the institutions granting us our public sector contracts.

We evaluate credit risk before the presentation of the offer. For public clients, we evaluate the origin of the funds, whether they are federal or state funds or whether they will come from a financing. At the same time, we evaluate the payment history of such client. In this way, we assure that there is an initial budget for the project. For private clients, we also evaluate their payment history and the origin of the funds for the project. The explanation of the credit risk is reviewed and approved by the committees of our senior management.

In addition, we periodically evaluate the reasonableness of our accounts receivable. In cases when an indication of collection difficulty exists, allowances for bad debts are created and charged to results in the same period. The allowance is determined based on management’s best judgment in accordance with prevailing circumstances at that time, modified by changes in circumstances. Our policy is not to recognize an allowance for doubtful accounts on contracts that require the customer to pay for the work not as it is performed, but only when the project is completed unless there are sufficient indicators that such receivable will not be collectible.

Occasionally, claims are initiated against project clients for additional costs that went above the contract price, or for amounts not includes in the original contract price, include orders to make changes to the project. These types of claims occur as a result of certain issues, such as delays attributed to the client, unit prices that are higher than expected, or changes to the scope of the initial project, that result in, directly and indirectly, additional costs. Frequently, these claims can serve as matters in long arbitration disputes, litigation, or proceedings with external experts, and, often, it may be difficult to predict with precision when these claims will be definitively resolved. When these types of matters occur and there are pending claims without resolution, we may invest significant amounts of working capital into the project in order to cover the excess costs while the claim in question is being resolved. With respect to change orders in particular, we may agree with the client with regards to the scope of the work that will be completed without agreeing on the price. In this case, it may be necessary to seek external experts and those external experts may provide valuations that are unfavorable to us, which we would be unable to control.

Construction backlog takes into account only those projects over which we have control. We consider ourselves to have control when we have a majority participation in the project, when we are assigned leadership and we have the power to make decisions over the relevant operating and financial decisions of the entity that holds the construction project. In a case in which there is contractual joint control, the percentage of the contract is incorporated in the backlog according to our participation in the association and our rights regarding liabilities and obligations regarding liabilities, as defined in IFRS 11 “Joint Arrangements.” For disclosure purposes only and separately, we include the backlog of joint ventures and associated companies, which are accounted for using the equity method. See Note 8(b) to our consolidated financial statements.

Long-Lived Assets

The long-lived assets that we have refer to property, machinery and equipment and concessions granted by the Mexican government and foreign governments for the construction, operation and maintenance of highways, bridges and tunnels, airport administration and municipal services.

The investment in concessions is classified either as an intangible asset, a financial asset (account receivable) or a combination of both based on the terms of service concession agreements.

75

A financial asset is originated when an operator constructs or makes improvements to the infrastructure and the operator has an unconditional right to receive a specific amount of cash or other financial asset during the contract term. An intangible asset is originated when the operator constructs or makes improvements and is allowed to operate the infrastructure for a fixed period after the construction ends. In this case the operator’s future cash flows have not been specified, because they may vary depending on the use of the asset and they are therefore considered contingent.

A combination of both – a financial asset and an intangible asset – is originated when the return/profit for the operator is partially provided by a financial asset and partially by an intangible asset.

We recognize and measure contractual obligations for major maintenance of infrastructure in accordance with IAS 37. We believe that periodic maintenance plans for infrastructure, whose cost is recorded in expenses in the period in which the obligation arises, are sufficient to maintain the concession in good operating condition, in accordance with the obligations specified by the grantor and to ensure the delivery of the related infrastructure in good operating use at the end of the term of the concession, ensuring that no additional significant maintenance costs will arise as a result of the reversion to the grantor. For airports the estimated major maintenance costs are based on the master development plan, which is reviewed and updated every five years.

When the effect of the time value of money is material, the amount of the provision equals the present value of the expenditures expected to be required to settle the obligation. Where discounting is used, the carrying amount of the provision increases in each period to reflect the passage of time and this increase is recognized as a borrowing cost. After initial recognition, we review provisions at the end of each reporting period and we adjust them to reflect current best estimates.

Adjustments to provisions arise from three sources: (i) revisions to estimated cash flows (both in amount and timing); (ii) changes to present value due to the passage of time; and (iii) revisions of discount rates to reflect prevailing current market conditions. In periods following the initial recognition and measurement of the maintenance provision at its present value, the provision is revised to reflect estimated cash flows being closer to the measurement date. The unwinding of the discount relating to the passage of time is recognized as a financing cost and the revision of estimates of the amount and timing of cash flows is a reassessment of the provision and charged or credited as an operating item within the consolidated statements of income and other comprehensive income.

Accounting Policy

Upon transition to IFRS, we elected to value certain land, buildings and major machinery and equipment at their fair value, using values calculated by appraisers, representing deemed cost for those assets. Subsequent to initial adoption of IFRS, and in accordance with IAS 16 and IAS 38, with respect to land, buildings and major machinery, equipment and concession investments, we apply a historical cost model, which consists of recording acquisitions at their acquisition or construction cost, or at fair value in the case of goods acquired through contributions, donations or in payment of debt.

For certain investments in concessions, a financial asset is recorded at fair value and is subsequently valued at amortized cost by calculating interest through the effective interest method at the date of the financial statements, based on the yields determined for each of the concession contracts. Interest income on financial assets from concessions are recognized within revenues, as they form part of our ordinary operations and as such, form part of the general objective of the concession activity, carried out regularly and thereby providing revenues on a routine basis.

Investments in concessions which result in the recognition of an intangible asset, are recorded at their acquisition value or construction cost. The comprehensive cost of financing accrued during the construction period is capitalized.

Expenditures for property, machinery and equipment are capitalized and valued at acquisition cost.

76

Depreciation is recognized so as to write off the cost or deemed cost of assets (other than freehold land and properties under construction).

We calculate depreciation on our fixed assets, such as buildings, furniture, office equipment and vehicles, using the straight-line method over the useful life of the asset, taking into consideration the related asset’s residual value. Depreciation begins in the month in which the asset is available for use. The depreciation of machinery and equipment is calculated according to the units of production method (machine hours used in regard to total estimated usage hours of the assets during their useful lives, which range from 4 to 10 years). Depreciation begins in the month in which the asset is placed in service. In investment in concessions, amortization as in the case of our investment in highways and tunnel concessions involving the use of facilities over the period of the concession is calculated by the units of production method. In the case of water treatment plants we consider treated water volumes. At the airport concessions, amortization is determined by considering the term of the concession, which is 50 years.

Financing costs incurred during the construction and installation of buildings and machinery and equipment are capitalized.

We review residual values, useful lives and depreciation methods at the end of each year and adjusted prospectively if applicable. If the depreciation method is changed, this is recognized in retrospectively.

Depreciation of property, machinery and equipment is recognized as part of the cost of sales of those assets which are in use and generate income. Depreciation of equipment used by our management is recognized in general expenses. Land and construction in progress are not depreciated.

We periodically evaluate the impairment of long-lived assets, in order to determine whether there is evidence that those assets have suffered an impairment loss. If impairment indicators exist, the recoverable amount of assets is determined, with the help of independent experts, to determine the extent of the impairment loss, if any. When it is not possible to estimate the recoverable amount of an individual asset, we estimate recoverable amount of the cash-generating unit to which the asset belongs. Where a reasonable and consistent basis of allocation can be identified, corporate assets are also allocated to individual cash-generating units, or otherwise they are allocated to the smallest group of cash-generating units for which a reasonable and consistent allocation basis can be identified.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, we reduce the carrying amount of the asset (or cash-generating unit) to its recoverable amount. An impairment loss is recognized immediately in profit or loss. When an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognized immediately in profit or loss.

The maintenance costs of airports, which are approved in the master development plan, are provisioned with a charge to results of the year; in the other concessions, the provision is created with a charge to results of the year for the amount which is expected to be disbursed.

Internal Control

Discount rates used to determine the value in use, which is the present value of discounted future net cash flows, are determined in real terms by calculating the weighted average cost of capital for each cash-generating unit, which in turn is calculated by estimating the cost of equity and the cost of debt incurred for each cash-generating unit. The cost of equity is calculated using the capital asset pricing model, which uses the beta coefficients of

77

comparable public companies in local and international markets. The cost of incurred debt is calculated based on the terms of debt currently outstanding for projects in-process as well as existing financial market conditions. The method we use to calculate the recoverable value of our cash-generating units takes into account the particular circumstances of the assets, including the terms and conditions of each concession, machinery and equipment involved, and intangible assets.

We evaluate indicators of impairment as part of the process to determine the recoverable values of cash-generating units. The indicators of impairment considered for these purposes include, among others, 1) the operating losses or negative cash flows in the period if they are combined with a history or projection of losses, 2) depreciation and amortization charged to results which, in percentage terms, in relation to revenues, are substantially higher than those of previous years, 3) the effects of obsolescence, 4) reduced demand for the services rendered, 5) competition and other economic and legal factors. The mechanism to calculate the recovery value is based on the specific circumstances of the concessions, machinery and intangibles. In the case of the concessioned routes, the projected revenues consider the projected vehicle flows, and assumptions and estimates are used relative to population growth and the peripheral economy of the concessioned route, temporary reductions in vehicle flows due to rate increases, commercial strategies to boost their use, among others, which may be determined and adjusted depending on the actual results obtained.

In addition, as part of the process to determine the recoverable values of our cash-generating units, when there are indicators of impairment, we perform sensitivity analyses that measure the effect of key performance variables on projected net cash flows, considering the most probable outcomes of those variables. The critical variables used in our sensitivity analyses for the determination of recoverable value consider those variables that create value in each of our projects. These include (i) operating revenues, (ii) costs of operation and (iii) macroeconomic conditions, including foreseeable changes in interest rates. Our analyses also include contractually agreed-upon values related to maintenance and other investments when we are contractually bound to incur such investments in certain projects. Variations in discount rates are taken into account considering general changes in market interest rates and are applied to three possible scenarios with respect to projections of revenues: an optimistic case, a probable case (base case) and a pessimistic case. We consider that this range of outcomes is sufficiently broad to help us analyze the limits of the value of each critical variable and can also be broad enough for us to effectively consider projects that are in their mature phase. Variations are considered with respect to individual variables as well as with respect to “cross variations” where we apply simultaneous changes to combined variables.

Periodically, we analyze and document if there is evidence of impairment indicators.

Types of Long-Lived Assets

Depending upon their operating status, projects related to long-lived assets or cash-generating units can either be in the construction phase or operating phase. Projects in the construction phase are composed of investments in the process of being executed (constructed), whereas projects in the operating phase involve operating risks.

In the case of highways, we participate in two main project types: concessions and public-private partnerships (PPPs). The main difference between these categories is that revenues for PPP projects are paid directly by the government (not users) and include fixed revenues in addition to variable revenues, which we believe improves our revenue profile and risk exposure arising from our highways portfolio. Projected variable revenue scenarios are taken from studies that forecast traffic volume, which we use as a base from which to determine future cash flows. These forecasts also take into account anticipated changes in toll levels and are prepared using statistical models based on historic behavior for each project. Operating expense projections are developed by the individuals in charge of the project operation. Projections for investment commitments are considered when such commitments are contractually required under the concession agreement. Projections are reviewed by operating committees and by the trusts in which both the governmental authorities and the project’s lenders participate.

In water treatment and transportation projects, the structure of the project differs only in that the service is not provided directly to the public at large, but instead to governmental entities for water and drainage systems. In these types of projects, revenues and expenses are related both to the demand for the services by the population as a whole and the operating capacity of the project. Typically revenues include a fixed component to recover investment and fixed operating and maintenance costs, as well as a variable component that depends on the volume of water processed. The sensitivity analysis in these cases is based primarily on population growth, which is the most decisive factor for a future service demand.

78

Our airport projects are regulated by five-year master plans negotiated with the Mexican government, in which our future investment commitments are established and in which the maximum tariff we can charge per passenger is set. These are high-volume projects in which the variable that most affects the value in use is revenue. The sensitivity analyses for these projects are based on different scenarios of passenger traffic and ability to recover the maximum tariff.

Our estimates for all projects may be based on assumptions that differ from, and may be adjusted according to, actual use.

Income Tax

Accounting Policy

We determine and recognize income tax expense as the sum of the tax currently payable and deferred tax. The tax currently payable is based on taxable profit for the year. Taxable profit differs from profit as reported in the consolidated statement of income and other comprehensive income because of items of income or expense that are taxable or deductible in periods different from when they are recognized in accounting profit or for items that are never taxable or deductible.

In December 2013, Congress approved the Mexican Tax Reform with among other things, eliminated the flat tax (“IETU”) and the tax consolidation regime. As a result of the elimination of the IETU, for accounting purposes we cancelled our existing deferred IETU recorded at the date of the Mexican Tax Reform. With regard to the previous tax consolidation regime, a deconsolidation option was established for groups that consolidated under that regime, discussed further below. Three alternatives for calculating deferral of. the tax payment stemming from the effects of deconsolidation as of December 31, 2013 were provided, as was a fractional payment scheme over the next five years.

As a result of the elimination of the tax consolidation regime, we and our subsidiaries have the obligation to pay tax related to the deconsolidation, which was deferred in accordance with the previous tax law. The tax was determined from the date of deconsolidation and will be payable in accordance with the options provided in the Income Tax Law issued in 2014 and over a 10-year period beginning in 2014, according with the tax reform of 2009, as described below.

A new optional tax regime, a “regime of fiscal integration” was introduced those groups of companies that meet conditions and requirements similar to the previous consolidation regime. The main features of this regime are as follows: (i) a minimum controlling interest of 80% in the voting shares of integrated companies is required by the integrating entity, (ii) it allows the deferral of a portion of income tax up to three years, establishing strict controls in current income tax and paid at the individual level, (iii) tax loss carryforwards from integrated or integrative companies which belong to previous periods may not be incorporated into the regime (only tax loss carryforwards which are generated from the enactment date of the change in the tax law may be incorporated into this regime), and (iv) an integrating factor is determined which is applied by all companies in the group, individually, to determine the income tax payable and amount to be deferred income tax over three years.

We elected to be in the new optional fiscal integration regime for group companies beginning in 2014, as permitted by the 2014 Income Tax Law, having presented the appropriate notice to the tax authorities.

Pursuant to Section XVIII of the transitional ninth article of the 2014 tax reform, and because we were a holding company through December 31, 2013 and as of that date were subject to the payment schedule contained in section VI of article four of the transitional provisions of the Income Tax Law published in the Official Gazette of the Federation on December 7, 2009, or Article 70-A of the Income Tax Act 2013 which was subsequently abrogated by the 2014 Tax Reform, we are required to continue to make payments, under the deferred payment schedule, that were generated from fiscal consolidation rules in the previous 2009 Mexican Tax Reform (discussed below).

79

We determine the tax provisions of foreign subsidiaries based on taxable income of each individual company.

We recognize the deferred income taxes from the applicable temporary differences resulting from comparing the accounting and tax values of assets and liabilities plus any future benefits from tax loss carryforwards. Except as mentioned in the following paragraph, we recognize deferred tax liabilities for all taxable temporary differences and deferred tax assets are recognized for all deductible temporary differences and the expected benefit of tax losses. We review the carrying amount of deferred tax assets at the end of each reporting period and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered.

We recognize deferred tax liabilities for taxable temporary differences associated with investments in subsidiaries, except where we are able to control the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax assets arising from deductible temporary differences associated with such investments and interests are only recognized to the extent that it is probable that there will be sufficient taxable profits against which to utilize the benefits of the temporary differences and they are expected to reverse in the foreseeable future.

We measure our deferred tax assets and liabilities at the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which we expect, at the end of the reporting period, to recover or settle the carrying amount of our assets and liabilities.

We recognize current and deferred taxes as income or expense in profit or loss, except when it relates to items recognized outside of profit or loss, as in the case of other comprehensive income, stockholders’ equity items, or when the tax arises from the initial recognition of a business combination, in which case we recognize the tax in other comprehensive income as part of the equity item in question or, in the recognition of the business combination, respectively.

We presume that for the purposes of measuring deferred tax liabilities and deferred tax assets for investment properties that are measured using the fair value model, the carrying amounts of such properties, will be recovered entirely through sale, unless the presumption is rebutted. The presumption is rebutted when the investment property is depreciable and is held within a business model whose objective is to consume substantially all of the economic benefits embodied in the investment property over time, rather than through sale. We reviewed our investment property portfolios and concluded that none of our investment properties are held under a business model whose objective is to consume substantially all of the economic benefits embodied in the investment properties over time, rather than through sale. Therefore, we have determined that the “sale” presumption set out in the amendments to IAS 12 is not rebutted.

Derivative Financial Instruments

We enter into derivative financial instruments to hedge our exposure to interest rate and foreign currency exchange risk including foreign currency forward contracts, interest rate swaps and combined interest rate and foreign exchange swaps (cross currency swaps), related to the financing for our construction and concessions projects.

Accounting Policy

We recognize initially the derivatives at fair value at the date the derivative contract is entered into and subsequently, we remeasure them at fair value at the end of each reporting period. Fair value is determined based on recognized market prices. When the derivative is not listed on a market, fair value is based on valuation techniques accepted in the financial sector. Valuations are conducted quarterly in order to review the changes and impacts on the consolidated results.

80

We recognize the resulting gain or loss from remeasurement to fair value in profit or loss unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship.

A derivative with a positive fair value is recognized as a financial asset; a derivative with a negative fair value is recognized as a financial liability. A derivative is presented as a non-current asset or a non-current liability if the remaining maturity of the instrument is greater than 12 months and it is not expected to be realized or settled within 12 months. We present other derivatives as current assets or current liabilities.

Hedge accounting

At the inception of the hedge relationship, we document the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, we document whether the hedging instrument is highly effective in offsetting changes in fair values or cash flows of the hedged item.

When the related transaction complies with all hedge accounting requirements, we designate the derivative as a hedging financial instrument (either as a cash flow hedge, a foreign currency hedge or a fair value hedge) at the time we enter into the contract. The decision to apply hedge accounting depends on economic or market conditions and economic expectations in the national or international markets. When we enter into a derivative for hedging purposes from an economic perspective, but such derivative does not comply with all the requirements established by IFRS to be considered as hedging instruments, the gains or losses from the derivative financial instrument are recorded in the results of the period in which it occurs. Our policy is not to enter into derivative instruments for purposes of speculation but certain instruments that we contract do not qualify to be accounted for as hedging instruments and are considered for accounting purposes as trading instruments and the fluctuation in fair value is recognized in the financial results of the period in which they are measured.

Effectiveness tests of derivatives that qualify as hedging instruments from an accounting perspective are performed at least once every quarter and every month, if there is a significant change.

For cash flow hedges (including interest rate swaps and interest rate options) and foreign currency hedges designated as foreign currency cash flow hedges and including exchange rate instruments, foreign currency swaps and foreign currency options, we recognize the effective portion within statement of comprehensive income as a component of other comprehensive income. We recognize the ineffective portion immediately in the interest income or expense of the period.

Amounts previously recognized in other comprehensive income and accumulated in equity are reclassified to results in the periods when the hedged item is recognized in results, in the same line item in the statement of income and other comprehensive income where the hedged item is recognized. However, when a forecasted transaction that is hedged gives rise to the recognition of a non-financial asset or a non-financial liability, the gains and losses previously accumulated in equity are transferred from equity and are included in the initial measurement of the cost of the non-financial asset or non-financial liability.

Interruption of hedge accounting

Hedge accounting is discontinued when we revoke the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or when it no longer qualifies for hedge accounting. Any accumulated gain or loss on the hedging instrument recognized in other comprehensive income remains there until the hedged item affects results. When a forecasted transaction is no longer expected to occur, the accumulated gain or loss is reclassified immediately to results.

81

Fair value hedges

The change in the fair value of the hedging instruments and the change in the hedged item attributable to the hedged risk are recognized in the line item in the statement of income and other comprehensive (loss) income relating to the hedged item.

Internal Control

Our activities are exposed to different economic risks which include (i) market financial risks (interest rate, foreign currency and pricing), (ii) credit risk, and (iii) liquidity risk.

We try to minimize the potential negative effects of the aforementioned risks in financial performance through different strategies. We use financial derivatives to hedge those exposures to the financial risks of operations recognized in the statement of financial position (recognized assets and liabilities), as well as firm commitments and forecast transactions which are probable to occur.

We only contract hedge financial derivatives to reduce uncertainty in the returns on projects. The financial derivatives which we enter into may be designated for accounting purposes as hedging instruments or as trading instruments, without affecting our objective of mitigating the risks to which we are exposed in the projects.

In interest rate hedges we enter into the instruments in order to fix interest rates and thus make the projects more feasible. We enter into exchange rate hedge instruments to reduce the exchange rate risk in projects whose labor costs and inputs are incurred in a currency different from that of their financing source. We enter into the financing in the same currency as that of the payment source.

The contracting of financial derivatives is in most cases related to project financing, for which reason it is quite common that the same institution (or its affiliates) which provided the financing also acts as the counterparty. This includes instruments which cover fluctuations in the interest rate and the exchange rate. In both cases, the derivatives are contracted directly with the counterparties.

Our internal control policy establishes that the contracting of credit and of the risks involved in the projects requires a collective analysis by representatives from the finance, legal, administration and operations departments, before they can be authorized. As part of such analysis we also evaluate the use of derivatives to hedge financing risks. Based on internal control policy, the contracting of derivatives is the responsibility of the finance and administration departments once the aforementioned analysis is concluded.

When evaluating the use of derivatives to hedge financing risks, we conduct sensitivity analyses of the different possible levels of the relevant variables, in order to define the economic efficiency of each of the different alternatives available to hedge the risk measured. We compare the obligations and/or conditions of each alternative in order to define the best one. Furthermore, we conduct effectiveness tests with the support of an appraisal expert to determine the treatment applicable to the financial instrument once it is entered into.

We maintain a policy of entering into financial instruments at the project level, and we do not enter into instruments involving margin calls or additional credit contracts to those authorized by our committees responsible for their performance, as no additional sources of liquidity are designated for those types of instruments. In those projects requiring collateral, the policy is that the necessary deposits are made initially or letters of credit (contingent) are established at the time they are entered into, in order to limit project exposure.

See “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Derivative Financial Instruments.”

Other Policies

Accounting for Real Estate Sales

Accounting Policy

We recognize revenues derived from sales of low income housing, residential environment, and real estate in accordance with International Financial Reporting Interpretations Committee “Agreements for the Construction of Real Estate” (or IFRIC 15) and IAS 18, the house or real estate development is completed and, when the risks and benefits of the housing have been transferred to the buyer, which occurs upon passage of title to the buyer.

For sales of developments in which financial resources are obtained from financial institutions, revenue is recognized only when the properties are completed, the respective financing is received and the deed had been finalized. When we provide financing, revenue is recognized upon the execution of the deed of delivery-receipt, which is the moment upon which the risks, benefits, rights and obligations of the property have been transferred to the buyer and only when is probable that the economic benefits associated with the transaction will flow to us. We retain neither ongoing management involvement in the property sold in the degree to which usually is associated with an owner, except for the reservation of title, which is released at the time the price has been paid in full and the deed is ultimately processed.

Our real estate inventories are divided into two large segments: land held for development and inventories in-process (which include both houses under construction and unsold finished houses).

Housing and housing development costs comprise at the cost of the acquisition of land, improvements and condition thereof, permits and licenses, labor costs, materials and direct and indirect costs. Borrowing costs incurred during the construction period are capitalized.

Land to be developed over a period of more than 12 months is classified under non-current assets and is recorded at acquisition cost.

The valuation of inventory, the control of the cost of sales and the related profit are recognized through a cost budgeting system. The cost budgeting system is reviewed quarterly and updated periodically when modifications are made to sales price or cost estimates of construction and development of the home. Variations in the original cost budget that require a change in value of inventory are applied to results in the period in which they are determined. Inventory costs include (i) the cost of land, (ii) rights, licenses, permits and other project costs, (iii) housing development costs, construction and infrastructure costs, (iv) financial cost incurred during the construction period and (v) administration and supervision of real estate. The costs related to real estate projects that are capitalized during development of the project and are applied to cost of sales in the proportion in which revenues are recognized.

Internal Control

To determine any possible impairment of our land held for development, we carry out appraisals every two years or more frequently when events or changes in circumstances indicate that the carrying amounts may not be recoverable. If the valuation is less than the carrying value of the inventory, an impairment loss is recorded in results of the period in which the impairment was determined.

If circumstances that previously caused the reduction no longer exist or when there is clear evidence of an increase in net realizable value due to a change in economic circumstances, the previously recognized impairment is reversed.

With respect to inventory in-process, approximately 84% of homes under construction and unsold finished homes are within the low-income sector, while the remainder is within the moderate-income sector. With respect to homes in the low income sector, sales of such homes are generally financed by government-sponsored housing fund programs, which provide financial aid to customers to stimulate home purchases in this sector. Prices of homes in

83

this sector are generally regulated by such government programs, thereby limiting our flexibility to establish sale prices. Sale prices in this sector are therefore sensitive to the availability of funding offered by the government under such programs as well as conditions prevailing in the Mexican economy, which in turn can be affected by global economic conditions. However, through 2014, we have not historically experienced significant fluctuations in sales in this sector and have been able to maintain a stable gross margin of between 30% and 35%. Despite the global financial crisis, Mexican governmental policies supporting housing development have continued, albeit at a slower pace. Although we expect that trend to continue, any strict price controls put in place by the Mexican federal government or inherent from adverse economic conditions in Mexico that exceed our current operating margin could cause an impairment with respect to housing in this sector.

With respect to homes in the moderate-income sector, we perform a review of estimated revenues and costs on a quarterly basis for the projects currently in progress, in order to evaluate the sector’s operating margin. Additionally, on an annual basis, we perform formal impairment tests based on discounted cash flow projections and to determine the expected rates of returns of the project. Such cash flow projections incorporate actual revenues and costs through the date of the evaluation as well as estimated future investments we expect to incur to complete and sell the project. Revenues are projected based on the current selling price of the home, considering any discounts that we may offer.

Selling prices for the moderate-income sector are based on market studies of what a willing buyer would pay, comparable prices for similar projects in the areas in which we develop and the general economic conditions in Mexico. We only offer discounts on sale prices of homes when sales prices have increased over time and the discount would not exceed the original sale price of the home. Our policy is not to grant discounts when the discounted sales price would result in a value lower than the carrying value of the inventory. Our management determines discounts on a home-by-home basis. Cost estimates are based on our cost budgeting system as discussed above. Impairment is recognized when the fair value less costs to sell is less than the carrying amount of the inventory. As in the low-income sector, we generally earn a gross margin of approximately 30% to 35% in this sector. Accordingly, we are only recognize impairment on inventories in the moderate-income sector if we offer discounts greater than our operating margin or otherwise significantly reduce our prices below our operating margin because of, for example, market forces or deteriorating economic factors.

In both the low-and moderate-income sectors, we have seen an increase of 22% in the last quarter of 2014 compared to the last quarter of 2013 and a decrease of 53% in the first quarter of 2015 in home sales, when compared to the same period in the prior year.

Other Critical Accounting Judgments and Estimates

See Note 5 to our consolidated financial statements for further information regarding additional critical accounting policies.

Recently Issued Accounting Standards Application of new and revised IFRS

i) Effective January 1, 2015, we adopted the following International Financial Reporting Standards and interpretations in our consolidated financial statements:

IFRS 9 Financial Instruments

IFRS 9 was issued in November 2009 and introduced new requirements for the classification and measurement of financial assets. IFRS 9 was subsequently amended in October 2010 to include requirements for the classification and measurement of financial liabilities and for derecognition, and in November 2013, to include the new requirements for general hedge accounting. Another revised version of IFRS 9 was issued in July 2014 mainly to include (a) impairment requirements for financial assets and (b) limited amendments to the classification and measurement requirements by introducing a ‘fair value through other comprehensive income’ (FVTOCI) measurement category for certain simple debt instruments.

Key requirements of IFRS 9:

• All recognized financial assets that are within the scope of IAS 39 Financial Instruments: Recognition and Measurement are required to be subsequently measured at amortized cost or fair value. Specifically, debt investments that are held within a business model whose objective is to collect the contractual cash flows, and that have contractual cash flows that are solely payments of principal and interest on the principal outstanding are generally measured at amortized cost at the end of subsequent accounting periods. Debt instruments that are held within a business model whose objective is achieved both by collecting contractual cash flows and selling financial assets, and that have contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding, are measured at FVTOCI. All other debt investments and equity investments are measured at their fair value at the end of subsequent accounting periods. In addition, under IFRS 9, entities may make an irrevocable election to present subsequent changes in the fair value of an equity investment (that is not held for trading) in other comprehensive income, with only dividend income generally recognized in profit or loss.

85

• With regard to the measurement of financial liabilities designated as at fair value through profit or loss, IFRS 9 requires that the amount of change in the fair value of the financial liability that is attributable to changes in the credit risk of that liability is presented in other comprehensive income, unless the recognition of the effects of changes in the liability’s credit risk in other comprehensive income would create or enlarge an accounting mismatch in profit or loss. Changes in fair value attributable to a financial liability’s credit risk are not subsequently reclassified to profit or loss. Under IAS 39, the entire amount of the change in the fair value of the financial liability designated as fair value through profit or loss is presented in profit or loss.

• In relation to the impairment of financial assets, IFRS 9 requires an expected credit loss model, as opposed to an incurred credit loss model under IAS 39. The expected credit loss model requires an entity to account for expected credit losses and changes in those expected credit losses at each reporting date to reflect changes in credit risk since initial recognition. In other words, it is no longer necessary for a credit event to have occurred before credit losses are recognized.

• The new general hedge accounting requirements retain the three types of hedge accounting mechanisms currently available in IAS 39. Under IFRS 9, greater flexibility has been introduced to the types of transactions eligible for hedge accounting, specifically broadening the types of instruments that qualify for hedging instruments and the types of risk components of non-financial items that are eligible for hedge accounting. In addition, the effectiveness test has been overhauled and replaced with the principle of an ‘economic relationship’. Retrospective assessment of hedge effectiveness is also no longer required. Enhanced disclosure requirements about an entity’s risk management activities have also been introduced.

We are in the process of determining the potential impacts on our consolidated financial statements resulting from the adoption of this standard.

IFRS 15, Revenue from Contracts with Customers

In May 2014, IFRS 15 was issued which establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. IFRS 15 will supersede the current revenue recognition guidance including IAS 18 Revenue, IAS 11 Construction Contracts and the related Interpretations when it becomes effective.

The core principle of IFRS 15 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Specifically, the Standard introduces a 5-step approach to revenue recognition:

• Step 1: Identify the contract(s) with a customer.

• Step 2: Identify the performance obligations in the contract.

• Step 3: Determine the transaction price.

• Step 4: Allocate the transaction price to the performance obligations in the contract.

• Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

Under IFRS 15, an entity recognizes revenue when (or as) a performance obligation is satisfied, i.e. when ‘control’ of the goods or services underlying the particular performance obligation is transferred to the customer. Far more prescriptive guidance has been added in IFRS 15 to deal with specific scenarios. Furthermore, extensive disclosures are required by IFRS 15.

We are in the process of determining the potential impacts on our consolidated financial statements resulting from the adoption of this standard.

86

IFRS 16 Leases

IFRS 16 (Leases) was issued in January 2016 and supersedes IAS 17 (Leases) and related interpretations. This new standard requires that most leases be presented in the statement of financial position for lessees under a single model, eliminating the distinction between operating and finance leases. Lessor accounting, however, remains largely unchanged and the distinction between operating and finance leases remains in effect. IFRS 16 is effective for periods beginning on or after January 1, 2019, with earlier adoption permitted if IFRS 15 has also been applied.

Under IFRS 16, a lessee recognizes a right-of-use asset and a lease liability. The right-of-use asset is treated similarly to other non-financial assets and depreciates accordingly and the liability accrues interest. This will typically produce a front-loaded expense profile (whereas operating leases under IAS 17 would typically have had straight-line expenses) as an assumed linear depreciation of the right-of-use asset and the decreasing interest on the liability will lead to an overall decrease of expense over the reporting period.

In addition, the financial liability is initially measured at the present value of the lease payments payable over the lease term, discounted at the rate implicit in the lease if the rate can be readily determined. If the rate cannot be readily determined, the lessee shall use their incremental borrowing rate.

However, a lessee may elect to account for lease payments as an expense on a straight-line basis over the lease term for leases with a lease term of 12 months or less and containing no purchase options (this election is made by class of underlying asset); and leases where the underlying asset has a low value when new, such as personal computers or small items of office furniture (this election can be made on a lease-by- lease basis).

IFRS 16 establishes different transitional provisions, including retrospective application or the modified retrospective application where the comparative period is not restated.

We are in the process of assessing the potential impact on our consolidated financial statements that could result from the adoption of this standard.

Amendments to IFRS 11 Accounting for Acquisitions of Interests in Joint Operations

The amendments to IFRS 11 provide guidance on how to account for the acquisition of a joint operation that constitutes a business as defined in IFRS 3 Business Combinations. Specifically, the amendments state that the relevant principles on accounting for business combinations in IFRS 3 and other standards (e.g. IAS 36 Impairment of Assets regarding impairment testing of a cash-generating unit to which goodwill on acquisition of a joint operation has been allocated) should be applied. The same requirements should be applied to the formation of a joint operation if and only if an existing business is contributed to the joint operation by one of the parties that participate in the joint operation.

Our administration does not anticipate that the application of these amendments to IFRS 11 will have a material impact on our consolidated financial statements.

Amendments to IAS 1 Disclosure Initiative

The amendments to IAS 1 give some guidance on how to apply the concept of materiality in practice. Our administration does not anticipate that the application of these amendments to IAS 1 will have a material impact on the our consolidated financial statements.

Amendments to IAS 16 and IAS 38 Clarification of Acceptable Methods of Depreciation and Amortization

The amendments to IAS 16 prohibit entities from using a revenue-based depreciation method for items of property, plant and equipment. The amendments to IAS 38 introduce a rebuttable presumption that revenue is not an appropriate basis for amortization of an intangible asset. This presumption can only be rebutted in the following two limited circumstances:

• When the intangible asset is expressed as a measure of revenue; or

• When it can be demonstrated that revenue and consumption of the economic benefits of the intangible asset are highly correlated.

87

Currently, we use the straight-line method for depreciation and amortization of property, and furniture, office equipment and vehicles and intangible assets for airport concessions; for machinery, we use the method of hours of use. Amortization of intangible assets for highway concessions is determined based on vehicle flow.

Our administration believes that the methods used are the most appropriate to reflect the consumption of the economic benefits inherent in the respective assets and accordingly, does not anticipate that the application of these amendments will have a material impact on our consolidated financial statements.

Amendments to IAS 12 Income Taxes

The amendments to IAS 12 (Income Taxes), clarify that unrealized losses in debt instruments measured at fair value and for tax purposes measured at cost, originate a temporal difference, regardless if the instrument holder expects to recover the book value of the instrument through its sale or its use. In addition, they specify that the book value in an asset does not limit the estimation of probable future taxable profits and that when comparing the deductible temporary differences with future taxable profits, the latter exclude tax deductions that would result from the reversal of the above mentioned deductible temporary differences. These amendments are effective for annual periods starting from January 1, 2017, with retrospective application, although early adoption is permitted.

We are in the process of assessing the potential impact that the adoption of these amendments could have in its consolidated financial statements.

Amendments to IAS 7 (Cash Flow Statement) Disclosure Initiative

Amendments to IAS 7 (Cash Flow Statement) require separate disclosure of the following changes in liabilities that arise from financing activities:

(i) changes in cash flows from financing activities;

(ii) changes by acquisition or loss of control in subsidiaries or other businesses;

(iii) exchange rate fluctuations;

(iv) changes in fair values; and other changes.

A way of complying with the new requirement is through a reconciliation between the opening and final balance of liabilities in the statement of financial position that arise from financing activities. Liabilities arising from financing activities are those whose cash flows are classified, or that will be classified in the future, such as financing activities cash flows in the statement of cash flow. The new disclosure requirements also apply to changes in financial assets as long as comply with the same definition.

These amendments are effective for annual periods beginning on January 1, 2017, with early adoption permitted, and entities are not require to submit comparative information when applied for the first time.

We are in the process of assessing the potential impact that the adoption of these amendments could have in its consolidated financial statements.

Effect of Application of the Critical Accounting Policies and Estimates on Results and Financial Position

Set forth below are the results derived from the application of the aforementioned policies and their effects on our consolidated financial statements as of and for the years ended December 31, 2015, 2014 and 2013.

Construction Contracts

Our consolidated financial statements for the year ended December 31, 2015 included a provision for costs relating to project terminations amounting to Ps.205 million and a machinery lease provision of Ps.512 million. Our consolidated financial statements for the year ended December 31, 2014 included a provision for costs relating to project terminations amounting to Ps. 370 million and a machinery lease provision of Ps. 368 million. Our consolidated financial statements for the year ended December 31, 2013 included a provision for costs relating to project terminations amounting to Ps. 743 million and a machinery lease provision of Ps. 387 million. See Note 23(a) to our consolidated financial statements. As of December 31, 2015, 2014 and 2013, our consolidated financial statements include an allowance for doubtful accounts related to construction contracts of Ps. 5,755 million, Ps. 1,457 million and Ps. 897 million, respectively. Allowances and provisions were recorded based on our best estimates and current circumstances. If these circumstances change, we may need to modify the amount of allowances and provisions we have recorded.

Below is a table of relevant projects with either upward and downward changes in gross profit and their corresponding accounting effect due to favorable or unfavorable adjustments to contracts based on the percentage-of-completion method. The net changes in project profitability from revisions in estimates, both increases and decreases, were a net decrease of Ps. 791 million, a decrease of Ps. 470 million and an increase of Ps. 51 million for the years ended December 31, 2015, 2014 and 2013, respectively. The projects are summarized as follows:

(1) Contract amounts were selected whose variation in gross margin was higher than Ps. 189 million, Ps. 111 million and Ps. 91 million for the years ended December 31, 2015, 2014, and 2013, respectively.

(2) The projects adjusted were principally Barranca Larga-Ventanilla Highway, Eastern Discharge Tunnel and Facchina Group of companies.

Income Tax

In 2015, we recorded a net tax of Ps. 3,223 million, which reflected the following components:

• a current ISR expense of Ps.890 million,

• a deferred ISR expense of Ps.2,333 million,

As of December 31, 2015, we recorded a deferred ISR asset of Ps.3,333 million, comprised of temporary differences of Ps.3,331 million (including benefit of deductible temporary differences on items included in other comprehensive income for Ps.161 million), and recoverable IMPAC of Ps.2 million. Additionally, we recorded a net deferred ISR liability of Ps.2,866million mainly of Ps.2,694 million of taxable temporary differences and Ps.172 million of taxable temporary differences on items included in other comprehensive income

89

In 2014, we recorded a net tax of Ps. 751 million, which reflected the following components:

• a current ISR expense of Ps. 285 million,

• a deferred ISR benefit of Ps. 1,034 million,

• a tax credits for foreign taxes paid of Ps. 2 million,

As of December 31, 2014, we recorded a deferred ISR asset of Ps. 6,164 million, comprised of temporary differences of Ps. 6,106 million (including benefit of deductible temporary differences on items included in other comprehensive income for Ps. 30 million), Ps. 55 million related with credit tax of foreign taxes paid and recoverable IMPAC of Ps. 2 million. Additionally, we recorded a net deferred ISR liability of Ps. 2,616 million mainly of Ps. 2,601 million of taxable temporary differences and Ps. 15 million of taxable temporary differences on items included in other comprehensive income.

In 2013, we recorded a net tax of Ps. (354) million, which reflected the following components:

• a current ISR and asset tax expense of Ps. 181 million,

• a deferred ISR benefit of Ps. 44 million,

• a current IETU expense of Ps. 21 million, and

• a deferred IETU benefit of Ps. 512 million.

As of December 31, 2013, we recorded a deferred ISR asset of Ps. 4,546 million comprised of net deductible temporary differences of Ps. 4,199 million, Ps. 250 million related to tax credits for foreign taxes paid and IMPAC recoverable of Ps. 97 million. Additionally, we recorded a net deferred ISR liability of Ps. 2,075 million mainly related to net taxable temporary differences, primarily of Ps. 2,126 million of taxable temporary differences and Ps. 51 million of benefit of taxable temporary differences on items included in other comprehensive income.

Tax losses as of December 31, 2013 have been recognized, as we believe we will be able to recover such losses based on our projections and business plan. Our existing level of backlog is expected to generate a greater volume of business in the future, resulting in increased taxable income that will compensate deferred tax assets recognized as of December 31, 2013.

At December 31, 2015 and 2014, we have recognized a deferred tax asset from tax losses carry forwards in subsidiaries of Ps.4,864 million and Ps.11,199 million, respectively, which we expect will be recovered in the future according with their taxable income projections and various operating strategies.

At December 31, 2015, the tax payable for deconsolidation is Ps.4,251 million, payable as follows: Ps.1,228 million in 2016 (reflected in current liabilities at December 31, 2015) and Ps.3,023 million from 2017 to 2024. The estimate that is reflected in the financial statements was determined based on the terms of the Mexican Income Tax Law. The long-term liability for Ps.3,023 million, was recognized at present value in the consolidated financial statements for Ps.2,617 million, with a cumulative discount effect for Ps.405 million. See Note 28 (e) to our consolidated financial statements. The aggregate tax liability for deconsolidation as of the date of this report is Ps. 1.228 million. At December 31, 2014, the tax payable for deconsolidation is Ps. 4,411 million, payable as follows: Ps. 183 million in 2015 (reflected in current liabilities at December 31, 2014) and Ps. 4,229 million from 2016 to 2023. The estimate that is reflected in the financial statements was determined based on the terms of the Mexican Income Tax Law. The long-term liability for Ps. 4,229 million, was recognized at present value in the consolidated financial statements for Ps. 3,699 million, with a cumulative discount effect for Ps. 530 million. See Note 28 to our consolidated financial statements

90

Derivative Financial Instruments

We have entered into interest rate swaps and options (designated as cash flow hedges), foreign currency swaps and options (designated as foreign currency cash flow hedges) and other derivative instruments (designated as trading derivatives as they do not meet hedge accounting requirements) for the terms of some of our credit facilities with the objective of reducing the uncertainties resulting from interest rate and exchange rate fluctuations. To date, the results of our derivative financial instruments have been mixed. Their mark-to-market valuation as of December 31, 2015, decreased our derivative liabilities by Ps. 46 million and decreased our derivative assets by Ps. 937 million. Those effects are reflected in our consolidated equity by Ps. 144 million and Ps. (288) million in our consolidated statement of comprehensive income for 2015. Their mark-to-market valuation as of December 31, 2014, increased our derivative liabilities by Ps. 75 million and increased our derivative assets by Ps. 192 million. Those effects are reflected in our consolidated equity by Ps. (68) million and Ps. 581 million in our consolidated statement of comprehensive income for 2014. Their mark-to-market valuation as of December 31, 2013, decreased our derivative liabilities by Ps. 131 million and increased our derivative assets by Ps. 280 million. Those effects are reflected in our consolidated equity by Ps. (207) million and Ps. 326 million in our consolidated statement of comprehensive income for 2013.

B. LIQUIDITY AND CAPITAL RESOURCES

General

Our principal uses of funds in the year ended December 31, 2015 were:

• Ps. 12,838 million for the payment of bank and securities debt;

• Ps. 574 million for the construction of the Mitla – Tehuantepec Highway;

• Ps. 352 million for the construction of the Barranca Larga – Ventanilla Highway; and

• Ps. 299 million for the construction of the Palmillas – Apaseo El Grande Toll Road.

Our principal sources of funds in 2015 were asset divestitures, third party financing for our construction and concessions projects, proceeds from project execution, debt refinancing through project bonds, and asset divestitures.

• Sales of 49% stake of the operational platform ICA OVT to one of Canada’s leading institutional fund managers, CDPQ. This platform includes, the Mayab Toll Road, Rioverde – Ciudad Valles highway, the La Piedad Bypass and the Acapulco Tunnel. The total proceeds received from this sale was Ps. 3,014 million

• Sale of a 100% stake in Proactiva for Ps. 1,240 million

• Sale of 3.02% of Series B Shares of GACN for Ps. 967 million

• Sale of a 100% stake in Rodio – Kronsa for Ps. 284 million

• Sale of Grupo Punta Condesa and Reserva Escondida for a total of Ps. 600 million

• Financing transaction with Santander for Ps. 2,250 million, with Series B Shares of GACN pledged as collateral

• Credit agreement with Deutsche Bank and Barclays for US$92 million, with Series B Shares of GACN pledged as collateral

• Credit Agreement with Deutsche Bank for US$66 million, with Series B Shares of GACN pledged as collateral

• Working Capital lines for Ps. 1,000 million for the Civil Construction Segment

91

Our expected future sources of liquidity include cash flow from our Civil Construction, Concessions and Airport segments, debt refinancing and asset sales within our Concessions segments, as well as from third party debt and equity for our construction, concessions and real estate projects. We cannot guarantee that we will be able to continue to generate liquidity from these sources particularly in light of our current financial situation. We expect our principal future commitments for capital expenditures to include capital requirements related to new and existing concessions. Each of the concessions we currently have under contract has long-term third party financing. Our policy and practice is to have indicative arrangements in place for third party financing at the time we participate in a bid offering for a concession. It is also our policy and practice to have arrangements in place for third party financing at the time we participate in a bid offering for a construction project, if the construction project requires financing. Construction projects that require third party financing include those without traditional public works payment procedures, where we receive an initial payment in advance and we invoice the client periodically after making expenditures for the project. Our traditional public works contracts, on the other hand, require spending simultaneously with or after payment of invoices by the public project client, thereby typically not requiring capital expenditures in excess of available funding. Because of our third-party financing policies and the procedures of our public works contracts, we expect our capital requirements related to concessions to vary less than our discretionary capital spending in other areas such as in non-public works construction, which are more often sensitive to market conditions, although there can be no assurance that our capital requirements related to concessions will not vary.

As of December 31, 2015 we had net working capital (current assets less current liabilities) of Ps.(25,699) million compared to Ps. 10,316 million as of December 31, 2014 and Ps. 5,537 million as of December 31, 2013. The decrease in our total net working capital as of December 31, 2015 compared to as of December 31, 2014 was primarily attributable to the reclassification to short-term of certain debt obligations in the Construction and Concessions segment and the three corporate bonds that may become due once there was a non-compliance on payment obligations. The decrease in our total net working capital as of December 31, 2014 compared to December 31, 2013 was primarily attributable to an increase in cash and receivables, and a decrease in notes payable.

From 2010 to 2013, we experienced a trend towards lower net working capital due in part to a larger portion of our concessions entering into their operating stage. During the construction phase of concession projects, we tend to experience higher working capital balances as a result of higher cash balances from the financing obtained for the concession project. During the operational phase of a concession, our cash balances may not be as high, as cash was utilized in the construction phase of the concession, and what remains is cash generated from the operation of the concession, including payables related to the operations of concessions. We expect this trend to continue as more of our concessions move from the construction phase to the operational phase. During 2014, we issued long-term debt that was used mainly to refinance short-term debt, causing a reversal of the trend towards lower net working capital. During 2015, the increase of the allowance for doubtful accounts, the reversal of the costs and estimated earnings in excess of billings and the reclassification to short-term debt of certain debt obligations had a negative impact in our Balance Sheet, decreasing our net working capital balance.

There can be no assurance, however, that the trend toward lower net working capital balances will not continue due to changes in the mix of projects under execution at any given time and their completion dates. Another trend toward our greater working capital needs is the growth of our Concessions segment, in which we have seen a trend toward greater investment requirements in infrastructure projects. When we perform construction under concessions, we generally must wait for an extended period—until after the concession has completed construction and begun operating—to recover the costs of construction. Finally, when constructing public works, we often experience a delay in payment, particularly in the initial phases of a project. The impact of the turmoil in the global financial system, and the recession in Mexico may result in delayed payment of monthly invoices for construction compared to what is historically typical.

The increase in 2015 in current liabilities was primarily due to the reclassification to short-term debt of certain debt obligations and the three Senior Notes that may become due once there was non-compliance on payment obligations. The decrease in 2014 in current liabilities was primarily due to the reduction of short-term debt. The increase in 2013 in current liabilities was primarily due to the slowdown in the collection cycle and its corresponding impact on the timing of our payments to providers. Our liabilities have increased in line with increases in our work volume of and number of projects, which typically result in an increase in current liabilities with subcontractors and suppliers.

92

Our cash and cash equivalents (including restricted cash) were Ps. 9,289 million as of December 31, 2015, of which Ps. 2,697 million was unrestricted cash held at GACN, as compared to Ps.8,413 million as of December 31, 2014 and Ps. 6,964 million as of December 31, 2013, As of December 31, 2015, we had a current ratio (current assets over current liabilities) of 0.56, as compared to a current ratio of 1.37 as of December 31, 2014 and 1.19 as of December 31, 2013.

Cash and cash equivalents (including restricted cash) at year-end 2015, included:

• Ps. 4,039 million, or 43% of our cash and cash equivalents, held in reserves established to secure financings, in connection with the SPC Projects, Acapulco Tunnel, the Kantunil-Cancun toll road, the Rio Verde-Ciudad Valles, the La Piedad bypass project, and the Palmillas- Apaseo El Grande Toll Road project, all of which are restricted; and

• Ps. 2,697 million, or 29% of our cash and cash equivalents, held in our Airports segment, which is unrestricted.

Some uses of cash and cash equivalents by certain of our less than wholly-owned subsidiaries require the consent of the other shareholders or partners, as applicable, of such subsidiaries, such as Constructora Meco S.A. in the case of our subsidiary for the Domingo Diaz project in Panama, and certain projects with Promotora del Desarrollo de America Latina, S.A. de C.V., in the case of our subsidiary for the construction of Acapulco Scenic Bypass project in Acapulco. In the case of these entities, the consent of our partners or other shareholders is only required with respect to the use of cash and cash equivalents outside of normal budgeted operations. The budget for normal operations is set by the board of directors of each of these entities, which are comprised of members appointed by both us and by the other partners or shareholders, depending on the terms of the bylaws of the entity, and in some cases, may be represented by equal numbers of members appointed by us and the other partner or shareholder. While the cash held in these entities is not designated for a specific use or set aside as a compensating balance, the requirements for its use could limit our access to liquid resources or limit us from freely deciding when to use cash and cash equivalents outside of normal operations. Additionally, a portion of our cash and cash equivalents are held in reserves established to secure financings and thus form part of our restricted cash balances. These resources form part of our restricted cash as presented in our statement of financial position. The reserve requirements of such financings could also limit our access to liquid resources and limit our ability to decide when to use our cash and cash equivalents. See “Item 3. Key Information—Risk Factors—A substantial percentage of our cash and cash equivalents are held through less-than-wholly owned subsidiaries or joint ventures, or in reserves, that restrict our access to them.”

We generated a net Ps. 7,120 million in operating activities during the year ended December 31, 2015, as compared to generating a net Ps. 1,993 million in operating activities during the year ended December 31, 2014. This increase can mainly be attributed to an increase in funding from suppliers and creditors combined with decreased payment on our accounts receivables. We generated a net Ps. 1,993 million in operating activities during the year ended December 31, 2014, as compared to generating a net Ps. 1,753 million in operating activities during the year ended December 31, 2013. This increase can mainly be attributed to an increase in the number and volume of projects under execution. Portions of our assets are pledged to a number of banks under credit arrangements, including: Credit Suisse AG, Cayman Islands Branch, Global Bank Corporation; Banco Inbursa, BBVA Bancomer Institución de Banca Multiple, Grupo Financiero BBVA Bancomer; Banco Mercantil de Norte, S.A. Grupo Financiero Banorter; Bancodel Bajo, S.A, Banco Nacional de Obras y Servicios Publicos, S.N.C; Bancolombia, S.A., Deutsche Bank AG, London Branch; Interamerican Credit Corporation and Sociedad Hipotecaria Federal. The assets we have pledged include collection rights under construction contracts, concessions, construction machinery and equipment, real property, dividend rights and shares of each of our financed concession projects. Notably among these, we have pledged, Autovia Necaxa-Tihuatlan, S.A. de C.V., (“Auneti”), our joint venture that operates the Nuevo Necaxa-Tihuatlan highway, our 50% interest in Los Portales, S.A., a real estate associate located in Peru, our interest in the El Realito project, our interest in the Agua Prieta project, our shares of Autopista Naucalpan Ecatepec, S.A. de C.V., (“ANESA”), the contractor for the Rio de los Remedios-Ecatepec toll Highway project, as well as the collection rights of the Rio de Los Remedios-Ecatepec project and Palmillas-Apaseo El Grande Toll Road. In general, assets securing credit arrangements will remain pledged until the arrangement secured by these assets expire. As a result of these arrangements, our ability to dispose of pledged assets requires the consent of these banks and our ability to incur further debt (whether secured or unsecured) is limited. At December 31, 2015, we had unrestricted access to Ps.4,816 million of our cash and cash equivalents, as compared to Ps.4,955 million at December 31, 2014 and Ps. 3,535 million as of December 31, 2013. See Note 6 to our consolidated financial statements.

93

Our debt agreements contain standard covenants and events of default applicable to us, including cross-defaults that permit our lenders to accelerate debt. The indentures under which we issued the Senior Notes at the holding company level in February 2011, July 2012 and May 2014, respectively (of the U.S.$350 million issued in July 2012, US.$150 million are currently outstanding as a result of our May 2014 tender offer), and under each of which we are currently in default, contain various covenants and conditions that limit our ability to, among other things: incur or guarantee additional debts; create liens; enter into transactions with affiliates; and merge or consolidate with other companies. In addition, our other debt agreements provide for various covenants that restrict the ability of us and our operating subsidiaries to incur additional indebtedness, sell fixed and other non-current assets and make capital distributions to us. We have also increasingly been required to accept clauses which, if invoked, typically require a borrower to pay additional amounts under a loan agreement as may be necessary to compensate a lender for any increase in costs to such lender as a result of a change in law, regulation or directive. As a result of these covenants, we are limited in the manner in which we conduct our business and may be unable to engage in certain business activities. Restrictive covenants in our project debt agreements restrict only the project contracting the financing agreement in which they are contained, and generally do not restrict our operating subsidiaries. See Note 27 to our consolidated financial statements and “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Indebtedness.”

In certain bidding processes we have also been required to prove, typically at the bidding level, our debt ratios (total debt divided by total assets) and liquidity ratios (short-term assets divided by short-term debt). The requirements related to these ratios vary. In certain projects, we were required only to disclose the existing ratios to the potential client, without a minimum requirement. In other bidding guidelines we have seen debt ratios required to be less than 0.7 or 0.8, and liquidity ratios required to be greater than 1.0 or 1.2. Our experience shows that these requirements can vary greatly from client to client and country to country. We have historically met or exceeded the debt and liquidity ratio requirements for the projects on which we have bid.

We have also been required to demonstrate minimum capital in order to participate in bids for construction contracts and concessions. The minimum capital requirements are not uniform across clients, and can also vary for the same client depending on a project’s type and magnitude. For example, in two bids with the Ministry of Communications and Transportation, we were required to have minimum capital of Ps. 280 million and Ps. 900 million, respectively. The state government of Jalisco, Mexico required minimum capital of Ps. 386 million for the Agua Prieta project, while the Atotonilco project’s client, the National Water Commission, required Ps. 1,000 million. We believe we will continue to be required to demonstrate minimum capital in order to participate in certain bids for construction contracts and concessions although the levels required will vary among clients.

Project Financing

We use a number of project financing structures to raise the capital necessary for our projects. We historically financed our construction operations primarily through advances from customers. Increasingly, we have been required to arrange construction-phase financing. This has typically been done through bank financing under limited - or non-recourse structures. Our ability to arrange financing for the construction of infrastructure facilities is dependent on many factors, including the availability of financing in the credit market.

In our Concessions segment, we typically provide a portion of the equity and our investment is returned over time once the project is completed. Concessions are an approach to financing public-sector projects through the private sector. In certain non-concession projects that are financed as part of Mexico’s public works financing program, payment of the contract price is deferred until the project is operational. Due to the nature of most infrastructure projects, which typically involve long-term operations, we do not recover our equity or debt contribution or receive payment under the contract until the construction phase is completed. Depending on the requirements of each specific infrastructure project, whether such project is a concession or not, we typically seek to form a consortium with entities that have expertise in different areas and that can assist us in obtaining financing from various sources. See “Item 3. Key Information—Business Overview—Infrastructure.” We anticipate that future revenues will depend significantly on our ability directly or indirectly to arrange financing for the construction of infrastructure projects.

94

In addition to providing equity capital to our project construction subsidiaries, we arrange third party financing in the form of loans and debt securities to finance the obligations of our projects. The revenues and receivables of the project are typically pledged to lenders and security holders to secure the indebtedness of the project. Recourse on the indebtedness is typically limited to the subsidiary engaged in the project.

We believe that our ability to finance our projects has in the past enabled us to compete more effectively in obtaining concessions projects. Providing financing for construction projects, however, increases our capital requirements and exposes us to the risk of loss of our investment in a project. Furthermore, our current liquidity constraints and financial situation may further limit our ability to finance projects. We attempted to compensate for this risk by entering into financing arrangements on terms generally intended to provide us with a reasonable return on our investment. We have implemented a policy to be selective in choosing projects where we expect to recover our investment and earn a reasonable rate of return. However, we cannot assure you that we will be able to realize these objectives or continue financing construction projects as we have in the past.

Indebtedness

Our total consolidated debt to equity ratio was 15 to 1 at December 31, 2015 and 2.9 to 1.0 at December 31, 2014. This deterioration in the debt to equity ratio at December 31, 2015 from December 31, 2014 mainly reflected an increase in U.S. Dollar-denominated bank debt, principally due to recognition in 2015 for doubtful accounts receivable, an adjustment in the determination of net realizable value of inventories, impairments to investment properties and concession assets, and the effect of depreciation of the Mexican peso relative to the U.S. Dollar. Our total consolidated debt to equity ratio was 2.9 to 1.0 at December 31, 2014 and 2 to 1.0 at December 31, 2013. This deterioration in the debt to equity ratio at December 31, 2014 from December 31, 2013 mainly reflected an increase in U.S. Dollar denominated bank debt, principally due to a depreciation of the Mexican peso relative to the U.S. dollar and also, to a lesser extent, to additional financings, including U.S. dollar-denominated financing for the acquisition of Facchina. See Item 13—Defaults, Dividend Arrearages and Delinquencies.

As of December 31, 2015, approximately 33% of our consolidated revenues and 45% of our indebtedness were denominated in foreign currencies, mainly U.S. dollars. Unless, as is our policy, we contract debt financing in the same currency as the source of its repayment, decreases in the value of the Mexican peso relative to the U.S. dollar may increase the cost in Mexican pesos of our debt service obligations with respect to our U.S. dollar denominated indebtedness and may also result in foreign exchange losses as the Mexican peso value of our foreign currency denominated indebtedness is increased. We have entered into cash flow hedges, including with respect to foreign currency cash flow, and other trading derivative instruments for the terms of some of our credit facilities with the objective of reducing the uncertainties resulting from interest rate and exchange rate fluctuations. To date, the results of our derivative financial instruments have been mixed and have not substantially affected our cash flows. See “Item 3. Risk Factors—Risks Related to Mexico and Other Markets in Which We Operate—Appreciation or depreciation of the Mexican peso relative to the U.S. dollar, other currency fluctuations and foreign exchange controls could adversely affect our financial condition and results of operations” and “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Derivative Financial Instruments.” Several of our subsidiaries have lesser exposure to foreign currency risk because a higher percentage of their revenues are denominated in U.S. dollars.

We and certain of our subsidiaries and unconsolidated affiliates have entered into debt and other agreements containing restrictive covenants that restrict the ability of us and our operating subsidiaries to incur additional indebtedness, sell fixed and other non-current assets and make capital. See Note 21 to our consolidated financial statements.

In 2015, our debt service obligations (principal and interest before commission expenses) totaled Ps.70.923 million for debt denominated in principally in pesos and U.S. Dollars, as compared to Ps. 65,700 million in 2014. As of December 31, 2015, our consolidated net debt (interest paying debt less cash and cash equivalents of our consolidated subsidiaries) was Ps.58,328 million, as compared to Ps.54,836 million as of December 31, 2014. Our net debt increased in 2015 by Ps.3,597 million due to an increase in U.S. Dollar denominated debt and depreciation

95

of the Mexican peso against the U.S. dollar. Although not an IFRS measure, we believe that consolidated net debt is a measure that provides useful information to our investors because we review net debt as part of our management of our overall liquidity, financial flexibility, capital structure and leverage. Consolidated net debt is composed of total debt (current debt and current portion of long-term debt plus long term debt) less cash and cash equivalents, each of which appears in our consolidated financial statements.

La Yesca

CPH is a special purpose subsidiary created to construct the La Yesca hydroelectric project. The terms of the La Yesca contract require that we secure financing for the project costs and limit disbursements during the construction phase to 90% of the cash cost of any certified work performed. We and the other shareholder of CPH have agreed to guarantee certain obligations of CPH under the project contracts, including the financing documents, subject to certain limitations, in the event of an early termination of the public works contract for the project. CPH obtained financing for the construction phase of the La Yesca hydroelectric project in the first quarter of 2008 from WestLB AG, which also structured the financing for the El Cajon hydroelectric project. The financing consisted of a U.S.$910 million line of credit to be used to cover construction costs and a U.S.$140 million revolving line of credit to be used to finance monthly working capital requirements and to be repaid from the construction line of credit, both of which contain various restrictive covenants typical in a project financing including, significantly, covenants limiting CPH’s access to additional cash other than what the project specifically requires until project completion and after final payment from the Mexican Federal Electricity Commission (Comision Federal de Electricidad) is received, as well as covenants limiting CPH’s ability to contract additional debt or guarantees. The U.S.$910 million construction line of credit was syndicated and has a term that lasts the duration of the construction period, subject to certain permissible extensions if the La Yesca project completion date is delayed. The repayment of the construction line of credit has occurred in three installments: (i) the first payment of U.S.$700 million was made on the date of provisional acceptance of the first turbine unit, (ii) the second payment of U.S.$342 million was paid on December 20, 2012 upon delivery of the second turbine unit in 2012, (iii) an additional payment of U.S.$147 million, which represented partial settlement for additional work undertaken on the project, was paid on December 23, 2013 and (iv) from May 2014 to December 2014 we collected an additional amount of Ps. 653 million (approximately U.S.$ 41 million).

Operating and Financial Review and Prospects—Operating Results—Critical Accounting Policies and Estimates—Derivative Financial Instruments.” The decision to enter into a derivative financial instrument is linked, in most cases, to the financing for a project, because the uncertainties we seek to reduce result from fluctuations in interest rates and exchange rates relevant to the project’s financing. Our derivative financial instruments as of December 31, 2015 are composed of instruments that hedge interest rate and exchange rate fluctuations.

When financing for our projects is at a variable interest rate, we may enter into interest rate hedges. Our interest rate hedges can include swaps to reduce our exposure to volatility risks; these swaps convert the interest rate from variable to fixed. In 2015, we had interest rate swaps in connection with the Nuevo Necaxca – Tihuatlan highway, the Palmillas- Apaseo El Grande toll road, the El Realito aqueduct, the Agua Prieta Water Treatment Plant and the Mitla-Tehuantepec highway.

We may enter into exchange rate hedges to reduce the foreign currency exchange rate risk where the currency used in the financing (and corresponding repayment) of the project is different from the currency in which we expect the project to incur labor, supply or other costs. In 2015, we entered into foreign exchanges hedges in connection with ICA Fluor working capital.

We may also enter into interest rate options that establish a maximum limit to the variable rate to capitalize financial costs. In 2015 and 2014, we entered into interest rate options in connection with Aqueduct II water supply.

It is our policy to enter into financial instruments at the level of each project, by the subsidiaries carrying out such project. Accordingly, the counterparty for a derivative financial instrument is often the same institution (or an affiliate) that provides the financing for the project to which that instrument is linked. We generally execute our derivatives directly with the hedge provider.

It is our policy not to enter into, and we have not entered into, derivative instruments that have margin calls or similar mechanisms that might impose additional obligations on parent companies of our subsidiaries. Since we enter into all our derivative instruments at the level of each project, hedge providers on occasion require additional financial support for the project subsidiary’s obligations. In those cases, our policy is to limit such support to cash collateral or a standby letter of credit provided at the time we enter into the derivative, so that the amount of such collateral or letter of credit is defined without any provision that would permit increase thereof or margin calls. It is also our policy that such collateral or letter of credit only be payable to the hedge provider upon an event of default under the hedge agreement.

Our internal control policies state that entering into derivative financial instruments requires collaborative analysis by representatives from our Finance, Legal, Administration and Operations areas, prior to approval. Once this analysis has been concluded and documented, the responsibility for entering into derivatives belongs to the Finance and Administration areas, in accordance with our internal control policy. Our policies do not expressly require authorization by the Corporate Practices, Finance, Planning and Sustainability Committee or the Audit Committee for entry into derivative financial instruments. Our policies limit the authority of those who can execute derivative financial instruments in certain ways, the most important of which are the following:

• Our Board of Directors establishes limitations on the amounts and types of derivative transactions that our officers may enter into on our behalf.

• The Board has vested our Chief Executive Officer with the power to enter into derivative financial instruments subject to certain limits on amount and complexity. The CEO has delegated this power using powers of attorney, also subject to caps on amount and complexity, to our Vice President for Finance and Administration and appropriate Finance officers.

103

• In the event that the CEO, the Vice President for Finance and Administration or an appropriate Finance officer wishes to enter into a derivative financial instrument that exceeds or goes beyond the limitations set by the board, the board’s specific authorization is required.

When assessing the potential use of derivatives to hedge financial market risks, we perform sensitivity analyses of possible outcomes of alternative derivative instruments to help us evaluate the economic efficiency of each alternative available to us to hedge the risk. We compare the terms, obligations and conditions to choose which alternative best suits our strategy. Once we enter into a derivative, we conduct effectiveness tests with the help of expert appraisers to determine its accounting treatment. See “Item 5. Operating and Financial Review and Prospects —Operating Results—Critical Accounting Policies and Estimates—Derivative Financial Instruments.”

Other Derivatives

In the second half of 2010, we entered into cross-currency swap transactions in order to mitigate our interest and exchange rate exposure in the Eastern Discharge Tunnel project to hedge prices of the tunnel boring machines used in this project. As of December 31, 2015, the fair value of these instruments is Ps. 17.8 million. These instruments are classified as hedging contracts for accounting purposes.

In February 2011, we entered into four coupon-only cross-currency swaps to hedge our foreign currency interest payment exposure related to our U.S.$ 500 million senior unsecured notes. For more information on our senior unsecured notes, see “Item 5. Liquidity and Capital Resources—Indebtedness—Empresas ICA.”. These instruments were classified as hedging contracts for accounting purposes. In June 2015, EMICA unwound the positive mark-to-market values held by all four hedge instruments in connection with the U.S. $ 500 million senior unsecured notes, in order to obtain additional liquidity equivalent to Ps. 394 million.

In August 2012, we entered into three coupon-only swaps to hedge our foreign currency interest payment exposure related to our then U.S.$ 350 million senior unsecured notes. These instruments were classified as hedging contracts for accounting purposes. In 2014, EMICA unwound the positive mark-to-market values held by all three hedge instruments in connection with the U.S. $ 350 million senior unsecured notes, in order to obtain additional liquidity equivalent to Ps. 111 million.

During 2012 and 2013 we entered into a series of cross currency swaps, forwards and options in connection with certain indebtedness incurred by CICASA, our Civil Construction sub holding company, ICASA, and Aeroinvest, with notional amounts equivalent to EUR $33.5 million and Ps. 750 million, respectively. These instruments were unwound on March 2016 and November 2015, respectively, in order to obtain additional liquidity in the amount of Ps. 32.4 million and US$3.2 million.

During 2013 we entered into two interest rate swaps (exchanging variable or floating rates for fixed rates): in our Concessions segment in connection with the project Pamillas with a notional amount of Ps. 1,006 million, and Aeroinvest loan with a notional amount of Ps. 750 million. The hedge instruments in connection with the Palmillas project were restructured with a notional amount of Ps. 1,946 million. The fair value as of December 31, 2015 of these instruments was Ps. 217 million in favor of the counterparty. The interest rate swap in collection with an Aeroinvest loan was unwound in order to obtain liquidity equivalent to US $472,000.

In December 2013, our subsidiary ICAPLAN entered into a cross currency swap with Credit Suisse in order to mitigate the fluctuations in exchange rates and interest rates related to a dollar-denominated, variable rate bridge loan. The fixed exchange rate is Ps.12.877 per U.S. dollar with a floating rate at the 28-day TIIE, plus a 6.32% spread. The primary position related to this instrument is dollar-denominated debt bearing interest at LIBOR. As part of the same transaction, ICAPLAN entered into an existing derivative financial instrument with Credit Suisse, which gives an affiliate of the lender the right to purchase 11.9 million shares of EMICA at a fixed price, through a novation with CICASA. This instrument was classified as a trading instrument.

In June 2014, our subsidiary ICAPLAN entered into a second cross currency swap with Credit Suisse in order to mitigate the fluctuation in exchange rates and interest rates related to a dollar-denominated, variable rate bridge loan. The fixed exchange rate is Ps. 13.07 per U.S. dollar with a floating rate at the 28-day TIIE, plus a 8.69% spread. The primary position related to this instrument is dollar-denominated debt bearing interest at LIBOR.

104

In July 2014, our subsidiary ICAPLAN entered into a zero-strike equity instrument with Credit Suisse, which consisted of (i) a debt transaction with a notional amount of Ps. 203 million and monthly payment obligations, and (ii) an option over 11,966,716 of our shares, to be settled in cash similar to a European-style collar with a zero cost premium. The option has a call at Ps. 28.2776 and a put at Ps. 18.8517. The debt portion has a termination date of December 8, 2015. The equity option has six possible expiration dates in 2015: October 27, November 7, November 10, November 17, November 24 and December 1.

All positive mark-to-market positions with Credit Suisse were unwound in order to generate US $10 million in liquidity to repay the debt position of the ICAPLAN derivative. The new outstanding balance of the debt portion is U.S.$ 0.8 million after the unwinding. As of December 31, 2015, there are no hedge positions linked with the Credit Suisse transactions.

On March 26, 2015, we unwound two of five derivatives entered into in connection with the U.S.$ 700 million in notes issued by EMICA in May 2014—a U.S.$ 200 million derivative with Morgan Stanley and a U.S.$ 200 million derivative instrument with Santander—and executed two new derivative instruments representing an income of US$5 million for our Company to replace the original instruments. As part of this transaction, EMICA liquidated a portion of the positive mark-to-market values held by the two derivatives . Subsequently, we executed new contracts for each of the original derivatives under which new terms were applied. In connection with the new U.S.$ 200 million Morgan Stanley derivative instrument, EMICA also purchased U.S.$ 1.5 million in long put options with a floor rate of Ps. 14.00 per U.S. dollar.

The new U.S.$200 million Morgan Stanley derivative retained the same termination date and the fixed coupon rate as the original contract, while the exchange rates were adjusted. The new derivative settled with an exchange rate of Ps. 14.60 per U.S. dollar, as compared to Ps. 12.884 per U.S. dollar for the original derivative.

The new U.S.$200 million Santander derivative retained the same the termination date, but the exchange rate and the coupon rates were modified. The new derivative settled with an exchange rate of Ps. 13.984 per U.S. dollar with a Party A Fixed Rate of 8.875% and Party B Fixed Rate of 9.83%, as compared to Ps. 12.884 per U.S. dollar with a Party A Fixed Rate of 8.875% and Party B Fixed Rate of 9.43% in the original derivative.

In July 2015, both the Santander and the Morgan Stanley derivatives were unwound in order to obtain additional liquidity equivalent to Ps. 508 million.

In January 2015, Mayab Consortium entered into a series of forwards at a 14.879 exchange rate, floor options at a 13.5 exchange rate and cap options at 16.5 with Morgan Stanley and Santander with a total notional amount of U.S. 100 million with maturity on October, 2015. These derivatives were considered trading positions for accounting purposes. In June, 2015 all Mayab Consortium derivatives were unwound and generated US $4 million.

Additional Sources and Uses of Funds

We may from time to time repurchase or sell our outstanding equity securities if market conditions and other relevant considerations make such repurchases or sales appropriate. The amount that we may use to repurchase our securities is authorized annually by our shareholders at our ordinary general meeting. See “Item 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchaser.”

Historically our clients have required us to issue bonds to secure, among other things, bids, advance payments and performance. In recent years, our clients have been increasingly requiring letters of credit and other forms of guarantees to secure such bids, advance payments and performance. We are currently in contact with issuers of letters of credit, but we cannot guarantee that we will be able to obtain all of the letters of credit required for our normal operations.

In recent years, our liquidity has also been adversely affected by the length of our average collection period for accounts receivable. Our average collection period for accounts receivable considered net of value-added tax was 275 days as of December 31, 2015, which is a 17% increase from 221 days as of December 31, 2014, primarily as a result of delays in the collection of accounts receivable, mainly in the Construction Segment. See Notes 7(b) and (f) to our consolidated financial statements.

105

Our principal sources of funds in 2015 were third party financing for our construction and concessions, proceeds from project execution, debt refinancing through project bonds, and asset divestitures totaling Ps. 6,692 million in proceeds, described in the “Liquidity and Capital Resources” section.

C. RESEARCH AND DEVELOPMENT, PATENTS AND LICENSES, ETC.

B. COMPENSATION

For the year ended December 31, 2015, the aggregate compensation of our directors and executive officers paid or accrued in that year for services in all capacities was approximately Ps. 88 million. In 2015, we paid management and non-management directors Ps.60 thousand net of taxes for each board meeting, Corporate Practices, Finance, Planning and Sustainability Committee meeting or Audit Committee meeting they attend. Since December 2015, the Corporate Practices Committee reduced the fee paid to the non-management directors fees to Ps.20 thousand net of taxes for each extraordinary meeting they attend, and excluded the management directors from any fee for attending either regular or extraordinary meetings.

As of April 29, 2016, we pay Ps. 60 thousand, net of taxes to non-management directors for each regular board meeting and Ps. 70 thousand net of taxes to the chair of each meeting. Additionally, we pay non-management directors Ps. 20 thousand net of taxes for each extraordinary board meeting, Corporate Practices Committee or Audit Committee meeting they attend.

Management Bonuses

Performance bonuses are paid to eligible members of management by the subsidiaries that employ them.

Our Corporate Practices Committee determines the bonuses for senior and middle management. Through April 29, 2015 the Corporate Practices, Finance, Planning and Sustainability Committee determined compensation for executive officers and the Chief Executive Officer. As of April 29, 2015, our shareholders approved the restructuring of the Corporate Practices, Finance, Planning and Sustainability Committee, dividing its responsibilities into two committees, the Corporate Practices Committee and the Finance, Planning and Sustainability Committee. The Corporate Practices Committee will determine the compensation of executive officers and the Chief Executive Officer. We have adopted the following policies regarding the calculation of the performance bonus:

• in years in which our income (calculated as described below) is 4% or less of our net worth, no bonuses will be paid,

• in years in which our income (calculated as described below) is greater than 4% of our net worth, up to 20% of the amount by which income exceeds 4% of net worth may be paid as bonuses.

Income for these purposes means income from all sources (including extraordinary items) before income taxes, employees’ statutory profit sharing and the bonus itself. Net worth for these purposes is our net worth as at the end of the year for which the bonus is being calculated, without giving effect to that bonus. This formula is subject to change by the Board of Directors, provided that all outside directors approve any such change.

A substantial portion of the shares beneficially owned by our directors and executive officers, along with other shares owned by our management, are owned through a trust, which we refer to as the management trust. The management trust is supervised by a technical committee consisting of members of our Board of Directors, and the Quintana family controls the vote of the management trust. This technical committee has broad discretionary authority over the corpus of this trust, including voting power over the shares contained therein and the conditions governing withdrawal of such shares. The technical committee is authorized to modify the terms of the management trust.

Bonuses are paid into the management trust and may be used by the technical committee to purchase shares, for the account of the bonus recipient. All dividends paid with respect to shares in the management trust are also deposited in the management trust. Cash dividends are, at the discretion of the technical committee, distributed to participants in the management trust or used to purchase shares at prevailing market prices for the benefit of the participants. Upon leaving us, participants in the management trust are entitled to receive the shares representing such participant’s interest in periodic installments. The management trust may, but is not required to, purchase the shares constituting such installments. All dividends received with respect of the shares owned by any former employee are paid to such former employee.

111

As described above, members of management that leave us are entitled to receive, in annual installments, the shares credited to their accounts in the management trust. Certain exceptions may be made to these rules from time to time to permit employees leaving us to receive their shares on an accelerated basis.

Additionally, and only for our executive management, we have a performance bonus plan, directly linked to the overall performance of the company and on a secondary basis to the performance of certain business units and the satisfaction of personal objectives. This bonus is payable in cash.

For the period 2014 certain bonuses were paid 2015, however given our policy and as described above no stock bonuses would be payable for the period 2015.

Options to Purchase Securities from Registrant or Subsidiaries

On March 31, 2000, we adopted a stock option plan pursuant to which our officers and senior management were entitled to annual stock options. Options were granted based on a percentage of the grantees’ annual base salary on April 29, 2003.

The stock option plan was terminated on April 16, 2004 and all options granted under the plan expired on April 29, 2010. We do not expect to grant stock options going forward.

Prior to their expiration on April 29, 2010, 113,485 options (on a post-reverse split basis) were exercised at a weighted average exercise price of Ps. 22.50. As of December 31, 2015, we had no stock options outstanding.

Pension Plan

In 2006, we created a defined benefit pension plan covering all active employees aged more than 65 who are part of our Board of Directors and have a minimum of 10 years of service as members of the board prior to their retirement. Until 2008, these employees were entitled to benefits beginning at the age of 55, with gradual reductions of their salary taken into account for pension purposes. Beginning January 1, 2008, the plan was revised to defer the early retirement age an additional two years, which such deferral ended in 2010. In 2012, the pension plan was further modified to provide lifelong benefits for executives as well as to establish an early retirement age of 60 for all employees, provided that they have 10 years of service with our Company. See Note 39 to our consolidated financial statements.

In 2011, the existing defined benefit pension plan was replaced as the vehicle for new enrollees with a new voluntary retirement savings plan offered to senior and executive management employees. This plan offers a pre-tax savings component of up to 10% of the employee’s taxable income, and corporate matching of up to 2.5%

For the year ended December 31, 2015, the present value of funded defined benefit obligation is Ps. 1.054 million.

In 2013, we also established a voluntary retirement plan for personnel over 60 with more than 10 years of service to the company.

C. BOARD PRACTICES

For a table setting forth our current directors and management, the expiration of their current terms of office and the period of time during which each has served in that office, see “Item 6. Directors, Senior Management and Employees—Directors and Senior Management.” We have no service contracts for our directors providing benefits upon termination of employment.

The Mexican Securities Market Law enacted by Mexico’s Federal Congress on December 30, 2005 (in effect since June 2006) altered the legal regime applicable to public companies in Mexico. In order to comply with the new law, our shareholders approved the amendment of our by-laws at an extraordinary general shareholders’ meeting on September 12, 2006.

112

Management Structure

Our management is vested in a Board of Directors and a chief executive officer. The duties of the Board of Directors are, among others, to set general strategy for the company, and for the legal entities controlled by it, and to appoint, supervise and, if and as necessary, remove the chief executive officer. In fulfillment of its duties and responsibilities, our bylaws, in accordance with the Mexican Securities Market Law, provide for our Board of Directors to be aided by one or more committees made up of independent directors.

Our bylaws provide for our Board of Directors to be comprised of no fewer than 5 and no more than 21 directors, of which at least 25% must be independent directors. Members of the Board of Directors are elected on a staggered basis. Each year, one-third of the members of the board are elected by our shareholders and, once elected, board members occupy their positions for the following three years without the need for shareholder ratification in the interim. Notwithstanding the foregoing, at any ordinary general shareholders’ meeting, any director can be removed by a 51% vote of our shareholders.

Any holder or group of holders of 10% of the voting capital stock of ICA may appoint a director. Shareholders that exercise such right may not participate in the appointment of remaining directors.

Our Board of Directors meets at least on a quarterly basis and has the duties and authority set forth in the company’s bylaws and in the Mexican Securities Market Law. The chairman of the Board of Directors is appointed by the shareholders at each annual ordinary general shareholders’ meeting, or by the Board of Directors itself, and has the authority to propose to the board the discussion and resolution of various matters, including proposals as to the independent directors that are to comprise the committee or committees that perform auditing and corporate practices duties, as well as the appointment and removal of the chief executive officer. The independent members of our board meet once per year with the chairman of our board. Under Mexican law, the chairman of our board may not be president of any of our committees

Our Board of Directors has the authority to establish special committees to assist the board in the performance of its duties. Our bylaws provide that audit and corporate practices duties may be delegated to one committee or to two separate committees at the discretion of the board.

Our chief executive officer is the main executive of the company, responsible for the management, direction and execution of our business, subject to the strategies set forth by the Board of Directors. The chief executive officer is also responsible for the fulfillment of resolutions approved by shareholders or the board. The chief executive officer is vested with broad agency authority. However, this authority is limited when it comes to exercising voting rights attached to the company’s shares in its subsidiaries. In regards thereto, the chief executive officer must act in accordance with instructions or policies provided by the board. Such authority is also limited in respect of sales of our real estate and equity holdings and in respect of transactions referred to in paragraph c), Section III of Article 28 of the Mexican Securities Market Law. In either such case, the chief executive officer may only act with the Board of Directors’ prior authorization. Furthermore, if the relevant transaction involves an amount equal to or exceeding 20% of the company’s net worth, the chief executive officer may only act with the prior authorization of our shareholders.

Board Practices

In response to the enactment of the Mexican Securities Market Law, our Board of Directors established the Corporate Practices Committee. On April 9, 2014, the annual shareholders meeting approved the division of the Corporate Practices, Finance, Planning and Sustainability Committee into two Board committees: the Corporate Practices Committee, with its duties set forth in Section I of Article 42 and other applicable provisions of the Mexican Securities Market Law, and the Finance, Planning and Sustainability Committee. On April 29, 2016, our Board of Directors combined the Finance, Planning and Sustainability Committee with the Corporate Practices Committee. The duties of the Corporate Practices Committee include providing an opinion on the nomination of the chief executive officer, assessing the performance of our senior management, providing an opinion on related-party transactions and compensation proposals for senior management and reviewing certain exempted actions of the Board of Directors, as well as the duties related to the former Finance, Planning and Sustainability Committee, such as proposing general guidelines for creating and monitoring compliance with our strategic plan, providing an

113

opinion on investment and financing policies proposed by our chief executive officer, providing an opinion on the assumptions in the annual budget and monitoring application of the budget and our control system, and evaluating risk factors that affect us and our mechanisms for controlling risk. As of April 29, 2016, Carlos Guzmán Bofill is chairman of the Corporate Practices Committee. Each member’s term on the committee runs concurrently with such member’s term on our Board of Directors. All members of the committee are independent directors as such term is defined in the Mexican Securities Market Law, and Bernardo Sepúlveda Amor, Jorge Ricardo Gutiérrez Muñoz and Elsa B. García Bojorges are independent directors as such term is defined in Rule 10A-3 under the U.S. Securities Exchange Act of 1934, as amended, or the Exchange Act.

The Mexican Securities Market Law requires that the Audit Committee be responsible for the duties set forth in Section II of Article 42 and other applicable provisions of the Mexican Securities Market Law. Such duties include evaluating our independent auditor, reviewing the audit report, opinion, and other documents prepared annually by the independent auditor, informing the Board of Directors of the quality of and any deficiencies in the company’s internal control mechanisms and regarding internal audits of the company or entities controlled by the company. As of April 29, 2016, the members of the Audit Committee are Elsa Beatriz Garcia Bojorges, as chair, and Luis G. Zazueta Domínguez and Carlos Guzmán Bofill, each of whom were independent as such term is defined in the Mexican Securities Market Law and in Rule 10A-3 under the Exchange Act. Each member’s term on the Audit Committee runs concurrently with such member’s term on our Board of Directors.

Both of the above committees are empowered to call shareholders’ meetings and hire independent counsel and other advisors, as they deem necessary to carry out their duties, including, in the case of the Corporate Practices Committee, the review of related-party transactions.

D. EMPLOYEES

As of each of the three years ended December 31, 2015, 2014 and 2013, we had approximately 22,116, 31,302 and 31,982 employees, respectively, approximately 45%, 41% and 39% of whom were permanent employees, respectively. The number of temporary employees employed by us varies significantly and is largely dependent on the level of our construction activities.

In Mexico, all of our employees, other than managerial and certain administrative employees, are currently affiliated with labor unions. Labor relations in each facility in Mexico are governed by a separate collective bargaining agreement, executed between the relevant subsidiary and a union selected by the employees of the relevant facility. Wages are renegotiated every year while other terms are renegotiated every two years. Labor relations for each construction project are governed by a separate collective bargaining agreement, which is coterminous with the project. Such agreements are reviewed once per year if the duration of the project so permits. Although, from time to time we have faced strikes at particular facilities or construction sites, we have never had a strike that materially affected our overall operations in Mexico. We believe that we have good relations with our employees.

E. SHARE OWNERSHIP

As of December 31, 2015, Mr. Bernardo Quintana and members of his immediate family, including our former directors Alonso Quintana Kawage and Diego Quintana Kawage and our general counsel Rodrigo Antonio Quintana Kawage, may be deemed to have had beneficial ownership of 45,076,793, or 7.4%, of our outstanding shares (excluding shares owned through the management trust). Through the management trust they hold 6,861,821 shares, or 1.1%, for a total of 51,938,614 or 8.5%, of our outstanding shares. None of our directors or officers has voting rights different from other shareholders, other than, as applicable, rights as a participant in the management trust or ICA Foundation Trust described below and rights of the position of director and/or officer.

114

Item 7. Major Shareholders and Related Party Transactions

A. MAJOR SHAREHOLDERS

The following table sets forth certain information regarding the ownership of outstanding shares as of December 31, 2015.

Identity of Person or Group	Amount Owned		Percentage(1)
Bernardo Quintana I(2)		45,076,793		7.4	%
Management Trust		21,631,035		3.5	%
Foundation Trust		8,343,608		1.4	%

(1) For all percentages, based upon 611,029,276 shares outstanding as of December 31, 2015.

(2) Reflects shares owned directly by Mr. Quintana and his family, including Rodrigo Antonio Quintana Kawage, and not through the management trust.

The major shareholders, as set forth in the table above, do not have voting rights different from other shareholders, other than Mr. Quintana’s rights as a participant in the management trust and foundation trust described below and as a member of our Board of Directors.

Our shares are the only class of security we offer in Mexico. We have no information as to the number of record holders in Mexico. As of December 31, 2015, 114,934,596 shares, or 18.8% of shares outstanding, were held in the form of CPOs, which have limited voting rights. See “Item 9. The Offer and Listing—Trading—Limitations affecting ADS Holders and CPO Holders.” As of December 31, 2015, 6.4% of our outstanding shares were represented by 9,815,476 ADSs representing four of our shares each, and such ADSs were held by 51 record holders with registered addresses in the United States. Because certain of the ADSs are held by nominees, the number of record holders may not be representative of the number of beneficial holders. See “Item 9. The Offer and Listing—Trading.” On January 8, 2016, we were notified by the New York Stock Exchange that the average trading price of our ADSs did not meet the New York Stock Exchange’s continued listing requirements.

Our directors and executive officers, as a group, beneficially own approximately 67,234,136 shares or 11.0% of the shares outstanding. A portion of the shares beneficially owned by our directors and executive officers (collectively, approximately 3.5% of the shares outstanding), are owned through a trust, referred to as the management trust. The technical committee of the management trust, which consists of members of our Board of Directors, has broad discretionary authority over the corpus of this trust, including voting power over the shares contained therein and the conditions governing withdrawal of such shares.

In April 2011, pursuant to the Mexican Securities Market Law, we announced that we had acquired 7,545,300 of our shares outstanding using the reserve for share purchases, at an average price of Ps. 26.47 per share, for an amount of Ps. 200 million. As part of our employee stock plan, 3,781,275 of these shares were transferred to the management trust at an average price of Ps. 28.05 per share.

In May 2012, pursuant to the Mexican Securities Market Law, we announced that we had acquired 4,207,000 of our outstanding shares using the reserve for share repurchases at an average price of Ps. 23.93 per share and at a total purchase price of Ps. 101 million. As part of our employee stock plan, 6,885,385 of these shares were transferred to the management trust at an average price of Ps. 20.65 per share.

The technical committee is authorized to modify the terms of the management trust. The technical committee, in its discretion, is authorized to distribute bonuses to participants in the form of cash and permit our current employees to withdraw shares held in the management trust. The technical committee generally has discretion over the sale of shares withdrawn from the management trust and generally has sought to conduct such sales in a manner that minimizes any adverse effect on the market price of the shares. Whenever an employee belonging to the management trust retires, his or her shares are released from the management trust so that such employee may dispose of his or her shares as he or she wishes.

In 1992, members of management donated 10% of their then-owned shares to Fundacion ICA, a non-profit organization formed to fund research and education activities in Mexico. In addition, certain former members of management donated 20% of their shares to Fundacion ICA. Fundacion ICA’s shares are held by a trust, which we

115

refer to as the foundation trust. We are entitled to appoint two of the five members of the foundation trust’s technical committee, while the remaining members are independent from us. Any disposition of the shares held by the foundation trust requires the approval of more than a simple majority of such technical committee and, therefore, may require approval of our representatives on this committee. Under the terms of the foundation trust, the shares held by Fundacion ICA, which, as of December 31, 2015, represented approximately 1.4% of the shares outstanding, are required to be voted in the manner specified by a majority of the technical committee. The Quintana family controls the vote of the foundation trust.

B. RELATED PARTY TRANSACTIONS

For a description of our related party transactions, see Note 38 to our consolidated financial statements.

Item 8. Financial Information

See “Item 18. Financial Statements” beginning on page F-1.

A. LEGAL AND ADMINISTRATIVE PROCEEDINGS

We are party to various legal proceedings in the ordinary course of business. Other than as disclosed in this annual report, we are not currently involved in any litigation or arbitration proceeding, including any proceeding that is pending or threatened of which we are aware, which we believe will have, or has had, a material adverse effect on us. Other legal proceedings pending against or involving us and our subsidiaries are incidental to the conduct of our and their business and we believe will be resolved in our favor or with an insignificant effect on our financial position, results of operations and cash flow. We believe that the ultimate disposition of such other proceedings individually or on an aggregate basis will not have a material adverse effect on our consolidated financial condition or results of operations.

Aqueduct II Water Supply System in Querétaro

By virtue of the construction of the project Acueducto II de Querétaro, various controversies emerged with the customer Querétaro State Water Commission (Comisión Estatal de Agua de Querétaro “CEAQ”), because during the work development, there were several developments that increased the value of the original budget. Therefore, on December 19, 2013, a formal payment request was presented through Notary Public. However, the CEAQ did not reply.

In April 2014, the claim was submitted before the District Judge in Civil Matter in Querétaro for the amount of Ps. 474 million.

However, the judge declared its incapacity to rule, considering that this issue must be heard by a judge in administrative matters; therefore, Suministro de Agua de Querétaro (“SAQSA”) filed an appeal.

The Court that heard of the appeal resolved that this was a civil, not an administrative, issue, but considered that it was within the competency of a District Judge of the Federal District, based on what was agreed in one of the modifying agreements to the contract, ordering that the lawsuit and its annexes were returned to SAQSA.

In November 2014, the claim was filed again, with the Seventh Judge of the District in Civil Matters in the Federal District. Therefore, in December 2014, CEAQ, Banobras, and one of the two supervisory companies were summoned.

In January 2015, the CEAQ and Banobras replied to the claim, opposing it on the grounds of lack of subject matter jurisdiction and territorial jurisdiction, that is, that the process must be in administrative matters and processed in the City of Querétaro.

The Court resolved that the jurisdictional challenges were unfounded. Therefore the CEAQ and Banobras filed an appeal. A decision was issued against them. Thus, both institutions filed an amparo action against the ruling of October 30, 2015, issued by the Third Unit Court in Civil and Administrative Matters of the First Circuit, which resolved to declare that the Third Judge of District in Civil Matters in Mexico City had jurisdiction.

116

On April 15, 2016, the Second Unit Court in Civil and Administrative Matters of the First Circuit issued a ruling resolving not to protect CEAQ and Banobras.

CEAQ and Banobras could file a revision recourse against this sentence.

SAQSA and the CEAQ have held several discussions to reach a conciliatory agreement. They are analyzing the technical concepts of the in the claim, the financial aspects to see how the debt could be paid, and finally, the legal aspects in order to conclude the legal process and execute a modifying agreement to the CPS.

Based on the evidence that SAQSA submitted in the claim, we consider that the possibility of recovering the debt are high.

Puebla Collector Road

The government of the state of Puebla, through the State Infrastructure Secretary, initiated a call for bids for the comprehensive project for the modernization of the México – Puebla highway and the Santa Ana – Chautempan freeway.

The original amount of the contract was of Ps. 670 million and it was completed with the amount of Ps.1,119 million. Therefore, there is a difference in favor of ICA of Ps. 450 million approximately.

During the execution of the works, various factors occurred that affected the work program and scope, causing cost overruns to ICA, such as:

1. Certain real estate property required for the execution of the project were not released by the Puebla State Government;

2. The project design was modified;

3. We incurred extraordinary expenses to obtain the necessary right of way, and

4. Social objections delayed the agreed program.

On December 5, 2013, a formal payment request was issued to the Puebla State Infrastructure Department, which did not respond. Consequently on August 22, 2014, we filed a claim for Ps. 472 million with the local courts of Puebla State.

Our management believes we have strong arguments in support of recovering the amounts described herein.

According to the legislation of the state of Puebla, before bringing a suit, the defendant must be summoned on at least three occasions to attempt to reach a conciliatory agreement. If a conciliatory agreement is not reached, the defendant is summoned and is granted a certain time to reply to the claim.

Due to the fact the Government of Puebla did not appear in the three conciliation hearings, it was summoned and during the time given for it to reply to the claim, the file that contained our demand was lost.

For the above reasons and due to the delays of the Court to expedite the document replacement, ICA filed several amparos to exercise pressure on the Judge and to order a document replacement, which he finally did. The government of the state of Puebla replied to the demand and to this date, April 15, 2015, it is in evidence submittal stage. On April 20, 2016, the expert evidence will be submitted, offered by ICA in financial engineering, costs, technical and accounting matters.

The government of the state of Puebla did not offer any expert evidence supporting their position. Therefore, we consider that there is a high probability of recovering the claim because our expert evidence is properly supported.

117

We estimate that the recovery process will take at least twelve months.

ICAMEX – TERMOTÉCNICA

There are two proceedings involving the ICAMEX-TERMOTECNICA Consortium.

Tax liability process involving ICAMEX – TERMOTÉCNICA based on the contract executed with ECOPETROL.

On September 28, 2012, CORPONOR notified the ICAMEX – TERMOTÉCNICA Consortium of a request for an out of court settlement to claim direct reparations from the Consortium and Empresa Colombiana de Petroleos ECOPETROL, S.A., for the environmental damage caused by the oil hydrocarbon spill that occurred at the Caño Limón—Coveñas oil pipeline. The claims filed by CORPONOR to return the ecosystem to its pre-spill condition total approximately U.S.$18.5 million.

The amount CORPONOR anticipates is required to recover the ecosystem and leave it in the condition it was before the spill is approximately US $18.5 million.

CORPONOR informed the involved parties that an out-of-court settlement hearing would be held on November 7, 2012. However, as an agreement was not reached at this hearing, CORPONOR had the right to file a legal action against the ICAMEX – TERMOTÉCNICA Consortium.

Consequently, on December 9, 2013, CORPONOR filed a petition for direct reparations with the Administrative Court of Northern Santander against Ecopetrol and the ICAMEX – TERMOTÉCNICA consortium, which was admitted by court order March 5, 2014.

On April 28, 2015, the initial hearing for the proceeding was held, with the opportunity to defend the exceptions stated in the reply to the lawsuit, but they were denied by the judge. After this determination, ICAMEX – TERMOTÉCNICA filed an appeal, which was resolved unfavorably on July 21, 2015 by the Council of State, which ruled that they must be resolved in the final judgment.

The file was returned to the Administrative Court of Northern Santander to continue with the proceeding. Through a decree on October 5, 2015, the parties were called to continue the initial hearing on January 26, 2016.

Notwithstanding the above, we do not consider it necessary to create a reserve for this lawsuit, as there is currently no legal indicator in the trial about a potential contingency. Even though the trials started in 2012, the court has had delays particularly during the evidentiary stage of the legal proceeding. Additionally, and based on the information available, including the review of the contract between the consortium and ECOPETROL, we believe that there is a valid defense that the oil spill is not attributable to the Consortium ICAMEX – TERMOTECNICA, and that the claims of the government are outside the contract scope.

Malla Vial

In April 2002, an arbitration tribunal in Colombia issued an award in favor of the IDU for US $ 2.2 million, as compensation for our alleged breach of contract, which, after the IDU obtained a judicial recognition of the arbitration award in Mexico in 2007, was paid in full. On January 8, 2009, the Mexican court recognized the payment in full.

In another proceeding related to the same project, the IDU filed a lawsuit against ICA before a court of Colombia for damages and contract default, for an approximate amount of US $4.7 million and filed a claim against the bonding company for the return of the advance payment that had not been amortized.

ICA also filed a counterclaim demanding indemnification and damages and losses for the amount of US $17.8 million. The Court orders to suspend all the actions against the bonding company until the resolution of the counterclaim filed by ICA.

118

Subsequent to the IDU’s announcement, political developments made this alleged agreement invalid. In June 2011, the suspension order blocking actions against the bonding company expired, raising the risk that, notwithstanding the unresolved counterclaims, the bond may be executed in an amount equal to U.S.$17 million plus interest, although such execution may be appealed. Nevertheless, we reached a second settlement agreement in principle with the IDU on all claims, and in December 2011 we filed a joint motion for the court to supervise and approve the conciliation procedure under Colombian law. On September 26, 2012, the parties signed a Conciliation Agreement and filed it for final review and approval by the tribunal. In order to decide on the matter, the tribunal requested that the attorney general provide an opinion on the Conciliation Agreement.

On February 28, 2013, the Administrative Court of Cundinamarca denied the conciliation with the IDU. Therefore, on March 8, 2013, we filed an appeal. The appeal was resolved in a ruling on April 17, 2013. In this ruling, the partial stay was granted against the decree in which the conciliation proposal was partially accepted and the file was sent to the Council of State for its resolution.

With regards to the executive process started by the IDU against Chubb de Colombia de Seguros S.A. and ICA, for the collection of the resolution that declared the contract expiration and enforced the pecuniary criminal clause (proceeding No. 2002-02258), the Court issued a ruling on October 18, 2013, in which it did not give a statement about the exceptions presented by ICA, and instead ruled in favor of the enforcement. An appeal recourse was filed on November 28, 2103, based mainly on the conciliation agreed with the IDU. On April 28, 2014, the Council of State admitted the waiver, thus putting an end to this proceeding.

Concerning the executive process started by the IDU against Chubb de Colombia de Seguros S.A. and ICA, for the collection of the resolution that enforced the amparo of down payment of the performance guarantee (proceeding no. 2003-00429), the Administrative Court of Cundinamarca stated that there was no evidence for the exceptions proposed by Chubb de Colombia de Seguros S.A. Therefore, it ruled in favor of the enforcement of the amount indicated in the claim filed on February 18, 2003. Subsequently, on May 3, 2013, an appeal was submitted with a request to nullify the ruling.

Through a resolution on October 24, 2013, the Council of State approved the conciliation agreed with the IDU. Therefore, the parties consider that the contract 462 of 1997 has been acquitted. As a result of the above, ICA made the payment of the sums involved in the conciliation, and the IDU filed its respective waiver in the executive proceeding no. 2002-2258, which was accepted through a decree of the Council of State, notified on May 6, 2014.

On May 14, 2014, the IDU presented the corresponding waiver to the proceeding no. 2003-00429, which had a negative ruling August 4, 2014 because the IDU representative did not have the express power to withdraw from the proceeding.

On August 14, 2014, the IDU lawyer filed an appeal for reversal, accompanied by a new power of attorney, through which the IDU authorized the lawyer expressly to withdraw from the proceeding.

On February 12, 2015, the Residing Judge partially ruled in our favor, accepting only the IDU waiver, arguing that the plaintiffs are two different entities; the IDU and the Capital District – Ministry of Public Works, and that the request was submitted only by the representative of the IDU. After this ruling, the representative of the IDU filed on February 20, 2015 an appeal for reversal, which was rejected at it was found unfounded through decree of April 29, 2015, in which the Council of State also ordered to continue with the proceeding.

On August 20, 2015, the Council of State granted the appeal filed by Chubb, against the original, issued by the Administrative Court of Cundinamarca on April 12, 2013.

On September 16, 2015, the Council of State gave notice to the parties. The IDU also filed an appeal for reversal. The proceeding is currently pending resolution with the Residing Judge requesting they present their concluding arguments.

Ciudad Juarez Airport

Parties purporting to be former owners of land comprising a portion of GACN’s Ciudad Juarez International Airport initiated legal proceedings against the airport to reclaim the land, alleging that it was improperly transferred to the Mexican government. As an alternative to recovery of this land, the claimants sought monetary damages of U.S.$ 120 million. On May 18, 2005, a Mexican court ordered GACN to return the disputed land to the plaintiffs.

However that decision, and three subsequent constitutional claims (juicios de amparo), permitted the case to be reconsidered, and as a result of such constitutional claims, the original claimants must now include the Ministry of Communications and Transportation as a party to the litigation since the Ministry of Communications and Transportation is the grantor of the concession title to the Ciudad Juarez Airport. On August 28, 2009, the Mexican federal government filed its answer to the claim, in which it requested that the trial be removed to federal court. In May 2010, the Court of Appeals granted the federal government’s request, giving the Federal Courts jurisdiction to hear the lawsuit. The plaintiffs filed a constitutional claim against this ruling before the Federal District Court in Chihuaha and on November 29, 2010, the District Court in Chihuaha confirmed the Court of Appeals’ ruling. Against this ruling, the plaintiffs filed an appeal (recurso de revision) before the Federal District Circuit Court, and on July 7, 2011, the Federal Circuit Court ruled that the plaintiffs’ constitutional claim should be heard by a District Court in Ciudad Juarez. In October 2011, the District Court in Ciudad Juarez denied the plaintiffs’ constitutional claim, against which, in November 2011, the plaintiffs filed a new appeal (recurso de revision) before the Federal Circuit Court. On January 7, 2012, the Federal Circuit Court confirmed that the District Court in Ciudad Juarez had jurisdiction to hear the claim. On April 30, 2012, the Federal District Court in Ciudad Juarez ruled that it did not have jurisdiction to hear the claim, and the determination of jurisdiction was sent to the Supreme Court. However, after the Federal District Court denied jurisdiction, a conflict arose that has been resolved by the Circuit Court. The Federal Circuit Court ruled on January 13, 2013 that a state or local court must hear the lawsuit rather than a federal court. The lawsuit is still underway at this time. As of May 15, 2016, the final resolution of this dispute remains pending.

In the event that any subsequent action results in a decision substantially similar to the May 18, 2005 court order or otherwise adverse to GACN, and the Mexican government does not subsequently exercise its power of eminent domain to retake possession of the land for our use, which we believe the terms of its concessions would require, our concession to operate the Ciudad Juarez Airport would terminate. In 2015, the Ciudad Juarez International Airport represented 4.1% of GACN’s consolidated revenues. Although we believe and have been advised by the Ministry of Communications and Transportation that under the terms of GACN’s concessions the termination of its Ciudad Juarez concession would not affect the validity of its remaining airport concessions and that the Mexican federal government would be obligated to indemnify GACN against any monetary or other damages resulting from the termination of its Ciudad Juarez concession or a definitive resolution of the matter in favor of the plaintiffs, we cannot assure you that we would be so indemnified. For this reason, our financial statements do not include a provision for this litigation.

We do not believe a material loss is probable in this matter.

Line 12 of the Mexico City Metro

1.a) Collection civil suit

On December 14, 2012, ICA, – together with its partners Carso Infraestructura and Construccion, S.A. de C.V. (“CARSO”), and Alstom Mexicana, S.A. de C.V. (“ALSTOM”) (collectively with ICA, the “Consortium”) –, filed a civil lawsuit against the Federal District Government (“GDF”), the Federal District Secretary of Works and Services, and the deconcentrated Federal District Subway Project office.

The claim sought the collection of additional and extraordinary works outside the scope of the Lump Work Agreement No. 8.07 C0 01 T.2.022, executed on June 17, 2008, for the execution of works for the Mexico City Subway Line 12 Project.

120

The claim was for Ps. 3,835 million pesos, plus the value added tax and Ps.118 million for financial expenses caused by the delay in the payment of work estimates, in addition to the delinquent interest, legal expenses and costs generated throughout the duration of the trial.

ICA’s portion of the claim amount was Ps. 2,690 million plus the value added tax.

On April 23, 2013, the Judge to whom the lawsuit was referred, decided not to go in-depth in the issue of the controversy, and referred the case to an administrative proceeding without impairing the procedural and substantial rights that we could enforce, if applicable, once that administrative set of proceedings was exhausted. For this reason, the parties tried to settle their differences in an out-of-court proceeding to solve technical and administrative issues.

On December 13, 2013, the parties agreed in the conciliation process in a joint proposal presented to the Mexico City Internal Control Authority, that both sides would be bound by an expert opinion on all technical and administrative matters. The expert was jointly nominated by our consortium and the client. On January 16, 2014, an expert opinion was issued confirming that additional work outside the scope of the contract had been performed, in the amount of Ps. 2,248 million.

Notwithstanding the expert’s opinion, Mexico City’s government subsequently disavowed the expert opinion. The conciliation process concluded without compliance with the agreed resolution, allowing each party to enforce its claims before competent courts located in Mexico City. We are engaged in litigation to enforce our rights both under the technical opinion rendered by the expert and for our other claims related to financial costs in the amount of Ps. 398 million, for a total amount claimed of Ps. 2,691 million. We believe that a favorable resolution is likely, as we have evidence, the jointly nominated expert opinion and the opinion of the external auditor hired by the GDF, all supporting the validity of the claim. Additionally, we are preparing a claim to enforce several rights which were not part of the analysis and technical opinion rendered by the expert, including the claim for additional maintenance works and rehabilitation of the Line 12 tracks.

On May 9, 2014, the Consortium filed a federal ordinary civil lawsuit against the Mexico City government, seeking enforcement of and compliance with the above-mentioned agreement of December 13, 2013 and seeking the payment for the amount of Ps. 2,247 million plus other costs estimated as of December 2014 to be Ps. 398 million.

Of the amounts mentioned in the paragraph above, 81.39% corresponds to ICA. Our management believes that as of the date of filing this report, we have strong arguments in favor of the amounts claimed and estimates that this recovery will take more than 12 months.

Through agreement issued by the Judge on February 25, 2015, it determined that said lawsuit was founded. So, it summoned the Federal District Government on March 3, 2015. The deadline for the GDF to reply to this summons ended on March 18, 2015.

After several jurisdictional challenges concerning the venue of the Federal Courts to resolve the controversy, and to the proper lawsuit integration, the proceeding is currently in its final evidence submittal stage.

On April 15, 2016, the file was referred for sentence issuance, which we believe will be favorable to the interests of the Consortium. Therefore, we believe it is very likely that the debt will be recovered.

In addition to the above-mentioned lawsuit, the Consortium filed two lawsuits and two other lawsuits are pending, through which we are demanding to GDF’s payment of various items that were not included in the expert opinion, such as: pending estimates, maintenance works, refurbishing of the tracks Atlalilco - San Andrés stretch, social effects, among others, for the total amount of Ps. 575.7 million.

On February 18, 2016, the Consortium filed a federal ordinary civil lawsuit against the GDF for the amount of Ps. 347 million, for the balance due to the Consortium and in charge of the GDF for the execution of Contract 022, which does not cover the execution of additional works and / or extraordinary works.

121

Also, on February 18, 2016, the Consortium filed a claim against the GDF for the effects of several social consequences of the Line 12 construction. The GDF and the Consortium entered into a debt acknowledgement agreement, which resulted in a favorable balance of the Consortium for Ps. 63 million.

We believe there are sufficient elements to prove the claim. Therefore, we believe the probability of recovering this debt is high.

The filing of two claims is pending, of which the notary payment requirements have been made to the GDF, consisting of the following:

1.1.a) For amounts related to various activities and works in connection with the maintenance of Line 12, which were not covered in the Public Work Contract 022, and in the Agreement of December 13, 2013, and which activities were performed at the direction of the GDF, generating a charge in favor of the Consortium for Ps.133.8 million.

1.2.b) For various activities and works related to the Line 12 refurbishment, different from those covered in the Contract 022 and in the Agreement of December 13, 2013, which were performed at the direction of the GDF, generating a charge in favor of the Consortium for a credit of Ps. 31.5 million.

As of April 15, 2016, these claims have not been filed yet, because it was necessary to wait 30 business days from the date when the notary payment request was made to the GDF. We expect that our submission of these claims in local court is forthcoming.

We believe we have a high probability of recovery of the debt because we believe there is sufficient evidence to support our claim.

1.b) Local Declarative Action filed by GDF

On April 24, 2014, the GDF filed an ordinary civil proceeding (“Declarative Action”) against ICA, CARSO, and ALSTOM individually.

In this claim, the GDF sought to obtain a legal judgment determining that the work contract related to the Line 12 was executed under the “lump sum” contract model and that for this reason, no modification to the amount and execution period is justified, and accordingly, that the GDF is not responsible for payments sought for any additional work that the Consortium might demand. In this lawsuit, the GDF is not demanding any amount.

In March 2015, this trial was in the evidence submittal state. This lawsuit does not implicate any direct economic contingency or risk of an adverse decision for the Corporation, because its only purpose is to obtain a declarative court judgment.

One of the legal challenges posed by the Consortium was the lack of jurisdiction of the Local Courts to hear the issues related to the Contract 022, because since federal resources had been involved, the federal legislation was applicable and, consequently, the Federal Courts would be the appropriate venue.

The Federal District Civil Judge confirmed its jurisdiction, and the Consortium appealed the refusal of jurisdiction acceptance. Therefore, the Civil Room that learnt of this appeal ruled in favor of the Consortium, ruling that federal jurisdiction applied.

Due to this ruling, the GDF promoted an “amparo”, which was denied. With this ruling, the GDF filed a revision action, which should have been resolved by a Collegiate Court, but was adopted by the Supreme Court of Justice of the Nation. The resolution is pending.

On March 12, 2015, the Judge 61 issued a ruling in the Declarative Action in favor of the GDF. Both the GDF and the Consortium filed an appeal, which was resolved by the Civil Court, again in favor of the GDF. Therefore, both the GDF and the Consortium again filed an amparo trial, which is currently pending in a Collegiate Court. The process as of April 15, 2016, is suspended until the issue of jurisdiction is resolved by the Supreme Court of Justice of the Nation.

122

In this claim, the Consortium does not have any economic risk because the GDF only challenged the legal statement by the Consortium related to stating before the judge if the work called Subway Line 12 was completed and stating that the agreement executed was a lump sum agreement.

1.c) Contract Settlement and Acquittal Process

In September 2014, the Consortium filed an indirect amparo claim against the imminent unilateral contract settlement and acquittance by the GDF through which the GDF intended to impose certain economic penalties for supposed work shortages or works executed improperly, as well as against the unconstitutionality of article 57 of the Federal District Law of Public Works.

The Sixteenth Judge of District in Administrative Matters granted to the Consortium a final stay so that GDF was prevented from enforcing the guarantees granted by the Consortium concerning the work contract settlement and acquittance. With this stay, the GDF is prevented from performing arbitrarily any action with the intention of imposing sanctions or charges, including the enforcement of the performance bond against the Consortium, until the amparo trial is resolved.

However, on January 9, 2015, the Consortium expanded the amparo claim for the fourth time because on December 5, 2014, the GDF issued the Unilateral Acquittance of the Public Work Contract. Thus, through agreement of February 27, 2015, this extension was admitted for proceeding by the Judge.

Until March 2015, this amparo was in the period of evidence submittal by the Consortium.

This amparo was resolved on September 11, 2015 in favor of the Consortium, which determined that the Unilateral Settlement Document must be declared without effect and that to that date the powers of the GDF to issue any settlement and / or a quittance related to the Public Work Contract 022 have expired.

Even though the amparo was resolved in favor of the Consortium, because the ruling was not favorable to the Consortium with respect to all the claims, both the Consortium and the GDF filed revision actions, which are pending resolution until the Supreme Court of Justice of the Nations issues a decision about the jurisdictional challenge.

In granting the amparo suspension, the District Judge first took as guarantee for the suspension the bond that the Consortium had submitted to guarantee hidden defects that could appear in the work. However, when the duration of said bond policy expired on May 6, 2015, the District Judge requested a new guarantee, which the Consortium did not grant. Consequently, the suspension was no longer in force and effect and the GDF demanded the bond payment from ACE Fianzas Monterrey.

ACE brought an action to nullify before the Federal Court of Tax and Administrative Justice. The resolution of this proceeding is still pending as of April 15, 2016.

In addition, the Consortium promoted an indirect amparo trial for the bond claim submitted by the GDF, which was still pending resolution as of April 15, 2016.

We believe that the decision in the aforementioned proceeding will be favorable to the interests of the Consortium.

ICA vs. Hermosa Provincia

On February 20 2014, ICA filed a claim against Constructora Hermosa Provincia, because that company sued ICA on several occasions for civil matters to pay several claims. The judges that have heard these claims have determined that the right of Constructora Hermosa Provincia to sue had expired.

123

The elements submitted to support the investigation and evidence the facts were the documents of the different civil actions that the Constructora Hermosa Provincia has filed. It was proven that the decisions established the expiration and is res judicata.

The prevailing problem is that the address of this company cannot be located. Thus, the lawyer and attorney-in-fact that file the claims have never indicated an address for service of notice and they have always indicated the courthouse as the address to be served notice.

In 2015, Constructora Hermosa Provincia filed a new civil claim, demanding the same claims against ICA, but now for the amount of Ps. 42.5 million superior to the previous demands. Therefore, a claim expansion will be presented.

We believe ICA does not have any economic risk in this matter. We reiterate that the rights of Hermosa Provincia have expired and is res judicata. However, it is necessary to deal with the claims and follow-up on them in order to resolve the matters filed by this company.

ICA vs. Ignacio Dominguez Parra and Simon Garcia Huizar (Mazatlán)

ICA filed a claim against Messrs. Ignacio Dominguez Parra and Simon Garcia Huizar, because even if they were paid various compensations ordered by civil authority twenty years ago, they have tried to obtain undue personal advantage, based on arbitrary, illegal, and inaccurate statements in several demands of guarantees, intending with it to obtain illegal profits for the amount of Ps. 469 million.

Ignacio Dominguez Parra filed an amparo action before the Court of District for fear of being arrested when he gave his statement before the Prosecutor’s Office. The amparo was denied.

In parallel, his partner, Simon Garcia Huizar, gave a statement to the Public Prosecutor’s Office. He said that he has not filed any action against ICA because twenty years ago ICA paid them for their claim, which was founded at that time.

With the above statement, the Federal Prosecutor’s Office issued the order of appearance and location of Ignacio Dominguez Parra. So, this individual filed a new amparo action, which resolution is currently pending.

As of this date, April 15, 2016, the preliminary investigation is on hold until the above-mentioned amparo action is resolved.

The Supreme Court of Justice of the Nation resolved that the amparo action to demand from ICA the previously mentioned amount was red judicata. Therefore, we believe that there is no economic risk for our Company as a result of this proceeding.

Bahía Petempich

ICA filed an ordinary commercial trial against the company Desarrolladora Bahía Petempich to demand the payment of Ps. 67 million, for the outstanding balance of the agreed-upon price for the construction of the project called Bahía Petempich, as well as for financial expenses, and for additional and extraordinary works.

Due to several procedural actions, the trial was suspended for three years and was not continued until March 2015, and as of April 15, 2016, was in the initial judgment issuance process.

We believe that the recovery of the amount claimed is feasible. However, the second appeal has to be developed, which is the appeal, amparo and, if applicable, revision.

Jose de Jesus Montes Lozano

The controversy originated in a highway accident that occurred on December 24, 1999 in the Autopista de Occidente, operated by Maxipistas, S.A. de C.V. (“MAXIPISTAS”), caused by excessive speed and a tire abandoned on the highway. Two people died.

Consequently, on December 14, 2001, the successors of the deceased demanded the payment of various compensations, although the payment amounts were not quantified, with the intention of quantifying them in the ruling issuance. So far, the amount is unknown.

On November 10, 2008, an initial ruling was issued, ordering MAXIPISTAS to pay to the plaintiff the amount for the moral and psychological damage that were quantified in the ruling. However, this sentence is not final because of several challenges submitted by the parties.

In January 2013, the plaintiff filed a claim before the Supreme Court of Justice of the Nation to finalize the ruling and to enforce it against MAXIPISTAS. However, we believe that the resolution will be favorable to us, because judgment is not final because the plaintiff has challenged the resolutions of the original Judge, mainly because the calculation of moral damage was not made in the proper procedural time. Thus, we consider that this is an issue that will not affect the equity of our Company at the end of the controversy.

Concerning the admission of the claim submitted before the Supreme Court of Justice of the Nation, we were never given notice because it has been dismissed.

In December 2013, the file was referred to the court of origin in Guadalajara, Jalisco, and it was expected that the plaintiff would start its award calculation claim, trying to justify the amount for moral damage concept.

This trial did not have any procedural movements during 2014.

In 2015, the plaintiff started the award calculation claim, reiterating what it demanded in its initial writing, which was for an approximate indemnification amount of Ps. 100. So, the Judge decided to process it, stressing that this award would occur according to a resolution that was not challenged by the plaintiff, which determined that the only indemnification applicable was for lost profits, meaning that the amount to be paid must match what each of the victims would have earned in minimum wage and in accordance with the life expectancy they had when they died, reducing significantly the aspiration of the plaintiff, that is, the indemnification would not be superior to Ps. 3 million.

The plaintiff appealed and to as of April 15, 2016, the proceeding is suspended until this appeal is resolved. We believe that the resolution will be in favor of the interests of ICA.

Indemnification request for expropriation of plots of land in Querétaro

In writing dated November 27, 2013, Inmobiliaria Baja, S.A. de C.V. (hereinafter, Inmobiliaria Baja), requested to the Ministry of Communications and Transportation the payment of indemnifications owed as a result of the expropriation of two plots of land, one of 159,887.75 square meters and another of 60,487.75 square meters located in the city of Querétaro, Querétaro.

This request was filed before the General Civil Aviation Direction (“the DGAC”) and on April 4, 2014, the DGAC refused to admit such request by arguing that the right to submit the request had expired.

Inmobiliaria Baja filed an indirect amparo action against the denial of the request by DGAC, which was processed before the Sixteenth Court of Justice in Administrative Matters of the First Circuit and it was resolved through a final ruling on July 31, 2014, granting the amparo to Inmobiliaria Baja so that the DGAC leaves without effect the official document number 4.1.-372 of April 4, 2014 through which it refused to admit the request of Inmobiliaria Baja, and it deals with its request that consist of determining the indemnification derived from the expropriations.

125

The First Collegiate Court of Circuit of the Auxiliary Center of the First Region, located in Mexico City, confirmed the above final ruling.

In compliance with the above, the DGAC admitted for processing the request of Inmobiliaria Baja, communicating to it that it would request to the Instituto de Administracion y Avaluos de Bienes Nacionales (hereinafter, INDAABIN) to determine through an appraisal the price that it would establish as indemnification of the areas expropriated.

Through various writings dated November 3 and 4, 2015, Inmobiliaria Baja requested to the DGAC to be given notice of the appraisals that the INDAABIN issued to determine the indemnification price, but no reply was obtained.

Inmobiliaria Baja filed an indirect amparo action against the failure and delay of the DGAC to give notice of the appraisals and to resolve the proceeding concerning the payment of the indemnifications owed, which was processed before the Sixteenth Court of District in Administrative Matters of the First Circuit.

In response to this amparo trial, the DGAC submitted the appraisals and Inmobiliaria Baja had knowledge of the appraisals, expanding its initial claim document to demand only the appraisal made with respect to the larger plot of land, because the amount of indemnification payment for it is derived from an appraisal that has expired.

In January 2014, Inmobiliaria Baja requested the appraisal of the plots of land, resulting in the following appraisals:

Larger plot of land; Ps. 271 million

Smaller plot of land; Ps.102 million

The INDAABIN issued the following appraisal:

Larger plot of land; Ps. 279 million and

Smaller plot of land; Ps. 210 million

We consider that the INDAABIN must correct the appraisal amount of the larger plot of land, because it is illogical that the smaller plot of land has a superior value. We believe that the probability of recovering the indemnifications is very high.

Rights of way of the Corredor Sur

Banco Hipotecario Nacional (“BHN”) filed and ordinary proceeding of a higher amount against ICA Panamá, S.A. for the effects caused by the use of rights of way of the Corredor Sur, which was admitted by the Third Court or Circuit on December 11, 2003. In it, BHN demanded the payment of the amount of US $2.5 million. Evidence submittal was set up for the month of February 2012.

In March 2012, the expert reports were presented, both by the experts of the Court and by the experts of the ENA (formerly ICA PANAMÁ) and BHN. The appraisal results show figures superior to the estimated amount, because of the indemnification of the property affected during the construction of the Corredor sur. The professional fees of the Court expert were rejected and submitted for review because they were considered to be excessive.

In March 2013, the Court issued a ruling in the first instance, in favor of BHN and establishing as compensation the sum of US $1.9 million. On March 5 and 19, BHN and the defendant, respectively, filed an appeal against the ruling, which is pending resolution.

126

On June 5, 2013, notice was given to the Specialized District Attorney’s Office in Civil Matters of the sentence, and on June 10, it requested its clarification and filed an appeal against it. Through decree no. 1656/456, dated October 31, 2013, the Court did not admit the clarification request. Through decree no. 1877/456 dated December 13, 2013, the appeal recourses filed by the parties were admitted against the ruling in the first instance no. 12/456-03. The recourses are pending of resolution.

Sonama Panamá, S.A. and Sonama, S.A., vs the Consortium ICA-FCC-MECO

On June 28, 2013, Sonama Panamá, S.A. and Sonama, S.A., filed a lawsuit for damages and losses against the members that make up the Consortium ICA-FCC-MECO, for the amount of $25.4 million balboas. The intentions of the plaintiffs are based on a presumed default of commercial and business obligations of the offer made to the members of the Consortium ICA- FCC-MECO, for the execution of works as subcontractor in the Project Pac-4.

The lawsuit filed was admitted through decree no. 1075, dated August 14, 2013, and on February 7, 2014, ICA acknowledged its receipt. On March 21, 2014, the lawsuit was replied to before the Seventh Court of Circuit of Civil Matters of the First Judicial Circuit of Panama.

On April 25 and May 6, 2014, ICA, FCC, and MECO filed evidence, counterevidence, and objections to them.

When the above was completed, the conclusion defense statements were submitted.

On September 24, 2015, the Seventh Court of Civil Circuit issued the ruling, which was favorable to the Consortium, ordering only the return of the amount that the Consortium had withheld from the companies Sonama and Sonama Panama, as well as the interest generated on it, for the amount of US $439,555.

Both parties filed an appeal, which is pending admission and referral to the Superior Court.

The main argument of the Consortium ICA-FCC-MECO to support its defense is on the fact that the parties never executed a contract supporting the plaintiffs claims. Therefore, creating a reserve for this cause was not considered to be necessary.

Dominican Republic Combined Cycle, L.L.C.

Dominican Republic Combined Cycle, L.L.C. is a subsidiary of ICATECH, with minority investment of Fluor Corporation, through which a combined cycle thermoelectric plant was built for the customer AES.

In connection with that project, the company Proyectos de Ingenieria Electromecanica, S.A., filed a civil trial against Dominican Republic Combined Cycle, L.L.C., for repair of moral damages and losses, payment of cost overruns, payment of two estimates, and return of the guarantee fund.

Due to the procedural irregularities of the plaintiff, the trial continues in the first instance and is processed in the Third Room of the Civil and Commercial Chamber of the Court of First Instance of Santo Domingo, Dominican Republic. We expect that the ruling will be issued in 2016, which could be challenged by the parties.

We believe that the resolution in this trial will be favorable to ICA Fluor, and as a result no reserve has been created. To this date, the total value of the contingency is of approximately US $16 million.

Labor lawsuits

There are several ongoing labor trials, filed against the various subsidiaries. Considering their nature, and even collectively, they do not represent a significant economic impact, because in the vast majority of the trials a conciliatory agreement is reached with the workers, in amounts equivalent to 30 and 45 days of wage. The average amounts could range between Ps. 10 to Ps. 2 million and in those cases where the entire process is exhausted, conciliatory agreements are reached to cancel up to 50% of their value.

127

Environmental Matters

There are currently no material legal or administrative proceedings pending against us with respect to any environmental matter in Mexico or the United States.

B. DIVIDENDS

We did not pay dividends in respect of our ordinary shares in any year between 2000 and 2015 and do not anticipate paying dividends in 2016.

The declaration, amount and payment of dividends are approved by the shareholders, upon the recommendation of the Board of Directors, and may only be paid from retained earnings from accounts previously approved by our shareholders, provided that the legal reserves have been duly created and losses for prior fiscal years have been paid. If our shareholders approve the payment of dividends, the amount of the dividends will depend upon our operating results, financial condition and capital requirements, and upon general business conditions. A number of our loan agreements contain covenants that restrict the ability of certain of our subsidiaries to make capital distributions to us and, accordingly, may affect our ability to pay dividends.

C. SIGNIFICANT CHANGES

Except as identified in this annual report on Form 20-F, no significant change in our financial condition has occurred since the date of the most recent audited consolidated financial statements contained in this annual report.

Our bylaws prohibit ownership of our shares by non-Mexican investors. As of December 31, 2015, 18.8% of our shares were represented by CPOs, and 6.4% of the total shares were CPOs held by the depositary. According to our depositary bank, as of December 31, 2015, 6.4% of our outstanding shares were represented by ADSs, and such ADSs were held by 51 holders with registered addresses in the United States. As of December 31, 2015, there were 611,029,276 shares outstanding.

As permitted by the Mexican Securities Market Law and the Rules promulgated by the Mexican Banking and Securities Commission, we may create a reserve fund from which we may repurchase our shares on the Mexican Stock Exchange at prevailing prices to the extent of funds remaining in this reserve account. We created this reserve account in 1992. Any shares so repurchased will not be deemed to be outstanding for purposes of calculating any quorum or voting at a shareholders’ meeting during the period in which we own such shares. As of December 31, 1999, 2,570,000 shares had been repurchased. After 1999, we did not make any repurchases until 2008. On April 3, 2008, our shareholders approved the use of Ps. 750.5 million for the repurchase reserve for the year 2008. In 2008, we repurchased 4,978,000 shares in the nominal amount of Ps. 69.0 million. On April 16, 2010, our shareholders approved the use of Ps. 726.8 million for the repurchase reserve for the year 2010. In 2010, we made no share repurchases. On April 14, 2011, our shareholders approved the use of Ps. 1,000 million for the repurchase reserve for the year 2011, and on November 17, 2011, our shareholders voted to increase such amount to Ps. 1,850 million and authorized management to carry out repurchases up to that amount in accordance with the Policy for the Acquisition and Placement of Own Shares. In addition, the November 17, 2011 shareholders’ meeting approved the cancellation of up to 32,748,689 repurchased shares, equivalent to approximately 5% of the shares outstanding as of December 31, 2010. In 2011, we repurchased 48,534,300 shares in the nominal amount of Ps. 996.6 million. In 2012, we repurchased 4,207,000 shares in the nominal amount of Ps. 100 million. On April 18, 2012, our shareholders approved the setting of Ps. 1,850 million as the maximum amount to be used for share repurchases. See “Item 10. Additional Information—Purchase by our Company of its Shares.”

On April 9, 2014 our shareholders approved the use of up to Ps. 2,140 million for the repurchase reserve and we repurchased 6,409,430 shares in the nominal amount of Ps. 139 million.

On April 23, 2015 our shareholders approved the use of up to Ps. 2,101 million for the repurchase reserve and we repurchased 4,156,059 shares in the nominal amount of Ps. 33 million

Trading on the Mexican Stock Exchange

The Mexican Stock Exchange, located in Mexico City, is the only stock exchange in Mexico. Founded in 1894, it ceased operations in the early 1900s, and was reestablished in 1907. The Mexican Stock Exchange is organized as a public company. Member firms are exclusively authorized to trade on the floor of the Exchange. Trading on the Mexican Stock Exchange takes place exclusively through an automated inter-dealer quotation system known as SENTRA, which is open between the hours of 8:30 a.m. and 3:00 p.m., Mexico City time, each business day. Trading is performed electronically and is continuous. Trades in securities listed on the Mexican Stock Exchange can, subject to certain requirements, also be effected off the Exchange. Due primarily to tax considerations, however, most transactions in listed Mexican securities are effected through the Exchange. The Mexican Stock Exchange operates a system of automatic suspension of trading in shares of a particular issuer as a means of controlling excessive price volatility. The suspension procedures will not apply to shares that are directly or indirectly (through ADSs or other equivalent instruments) quoted on a stock exchange outside Mexico. Settlement is effected two business days after a share transaction is effected on the Mexican Stock Exchange. Deferred settlement, even if by mutual agreement, is not permitted without the approval of the Mexican Banking and Securities Commission. Most securities traded on the Mexican Stock Exchange are on deposit with S.D. Indeval Institucion para el Deposito de Valores, S.A. de C.V., a privately owned central securities depositary that acts as a clearing house, depositary, custodian and registrar for Mexican Stock Exchange transactions, eliminating the need for the physical transfer of shares.

The Mexican Stock Exchange is one of Latin America’s largest exchanges in terms of market capitalization, but it remains relatively small and illiquid compared to major world markets, and therefore subject to greater volatility.

As of December 31, 2015, 137 Mexican companies, excluding mutual funds, had equity listed on the Mexican Stock Exchange. In 2015, the ten most actively traded equity issues in the IPC Index (Indice de Precios y Cotizaciones) (excluding banks) represented approximately 87% of the total volume of equity issues in the IPC traded on the Mexican Stock Exchange. Although the public participates in the trading of securities, a major part of the activity of the Mexican Stock Exchange reflects transactions by institutional investors. There is no formal over-the-counter market for securities in Mexico. The market value of securities of Mexican companies is, to varying degrees, affected by economic and market conditions in other emerging market countries.

Limitations Affecting ADS Holders and CPO Holders

Each of our ADSs represents four CPOs, and each CPO represents a financial interest in one share of common stock. Each share entitles the holder thereof to one vote at any of our shareholders’ meetings. Holders of CPOs are not entitled to vote the shares underlying such CPOs. Such voting rights are exercisable only by the CPO trustee, which is required to vote all such shares in the same manner as the holders of a majority of the shares that are not held in the CPO trust and that are voted at the relevant meeting.

Whenever a shareholders’ meeting approves a change of corporate purpose, change of nationality or restructuring from one type of corporate form to another, any shareholder who has voted against such change or restructuring has the right to withdraw from us and receive an amount equal to the book value of its shares (in accordance with our latest balance sheet approved by the annual ordinary general meeting), provided such shareholder exercises its right to withdraw during the 15-day period following the meeting at which such change or restructuring was approved. Because the CPO trustee is required to vote the shares held in the CPO trust in the same manner as the holders of a majority of the shares that are not held in the CPO trust and that are voted at the relevant meeting, appraisal rights will not be available to holders of CPOs.

Under Article 51 of the Mexican Securities Law, holders of at least 20% of our outstanding shares may have any resolution adopted by a shareholders’ meeting suspended by filing a complaint with a court of law within 15 days after the close of the meeting at which such action was taken by stating that the challenged action violates Mexican law or our corporate charter. To be entitled to relief, the holder (or the CPO trustee, in the case of CPOs) must not have attended the meeting or, if such holder attended, must have voted against the challenged action. Such relief will not be available to holders of CPOs or ADSs.

Item 10. Additional Information

A. MEMORANDUM AND ARTICLES OF INCORPORATION

Set forth below is a brief summary of certain significant provisions of our bylaws and Mexican law. This description does not purport to be complete and is qualified by reference to our bylaws, which have been filed as an exhibit to this annual report. For a description of the provisions of our bylaws relating to our Board of Directors and statutory auditors, see “Item 6. Directors, Senior Management and Employees.”

Organization and Register

We are a sociedad anonima bursatil de capital variable organized in Mexico under the Mexican Securities Market Law (Ley del Mercado de Valores) and the Mexican Companies Law (Ley General de Sociedades Mercantiles). We were registered in the Public Registry of Commerce of Mexico City on July 25, 1979, under folio number 8723. Our object and purpose according to Section 2 of our bylaws is (a) to hold an interest in the capital stock or equity of all types of legal persons; (b) to acquire any type of rights on all types of securities, of any type of legal person, as well as to dispose of and negotiate such securities; (c) to act as agent or representative of natural or legal persons; (d) to undertake all types of commercial or industrial activities allowed by law; (e) to obtain all types of loans or credit instruments; (f) to grant any type of financing or loan to companies, associations, trusts, and institutions in which our Company has an interest or holding; (g) to grant all types of personal and real guaranties, and guaranties for obligations or credit instruments to companies, associations, trusts, and institutions in which our Company has an interest or share; (h) to subscribe to and issue all types of credit instruments, as well as to endorse them; (i) to acquire, lease, usufruct, exploit, and sell chattels and real property required for its establishment, as well as to purchase and sell other things that are required to achieve its objectives; (j) to acquire, use and in general, dispose of industrial property rights, as well as copyrights, options thereon and preferences; and (k) to enter into, grant, and execute all acts, regardless of their legal nature, which it deems necessary or convenient for the realization of the aforementioned objectives, including associating with other national or foreign persons.

Voting Rights

Each share entitles the holder thereof to one vote at any meeting of our shareholders. Holders of CPOs are not entitled to vote the shares underlying such CPOs. Such voting rights are exercisable only by the CPO trustee, which is required to vote all such shares in the same manner as the holders of a majority of the shares that are not held in the CPO trust and that are voted at the relevant meeting. ADS holders are entitled only to the rights of CPO holders and thus are not entitled to exercise any voting rights with respect to the shares or to attend our stockholders’ meetings.

Under Mexican Law, holders of shares of any series are entitled to vote as a class on any action that would prejudice the rights of holders of shares of such series but not rights of holders of shares of other series, and a holder of shares of such series would be entitled to judicial relief against any such action taken without such a vote. The determination whether an action requires a class vote on these grounds would initially be made by our Board of Directors or other party calling for shareholder action. A negative determination would be subject to judicial challenge by an affected shareholder, and the necessity for a class vote would ultimately be determined by a court. There are no other procedures for determining whether a proposed shareholder action requires a class vote, and Mexican law does not provide extensive guidance on the criteria to be applied in making such a determination.

Under the Mexican Securities Market Law and the Mexican Companies Law, the shareholders are authorized to create voting agreements. However, shareholders must notify our company of any such agreements and make disclosure to the public. Our bylaws require that any voting agreement that involves more than 5% of our outstanding shares be authorized by our Board of Directors.

131

Shareholders’ Meetings

General shareholders’ meetings may be ordinary meetings or extraordinary meetings. Extraordinary general meetings are those called to consider certain matters specified in Article 182 of the Mexican Companies Law, including, principally, amendments of the bylaws, liquidation, merger, spin-off, change in nationality and transformation from one type of company to another. General meetings called to consider all other matters are ordinary meetings.

An ordinary general meeting must be held during the four months following the end of each fiscal year to consider the approval of the report of our Board of Directors regarding our performance and our consolidated financial statements and that of certain of our subsidiaries for the preceding fiscal year, to elect directors and to determine the allocation of the profits of the preceding year. At such ordinary general meeting, any shareholder or group of shareholders representing 10% or more of the outstanding shares has the right to appoint one director. The shareholders establish the number of directors at each annual ordinary general meeting.

The quorum for ordinary general meetings is 50% of the outstanding shares and action may be taken by a majority of the shares present. If a quorum is not present, a subsequent meeting may be called at which action may be taken by holders of a majority of the shares present regardless of the percentage of outstanding shares represented at such meeting. The quorum for extraordinary general meetings is 75% of the outstanding shares, but if a quorum is not present a subsequent meeting may be called. The quorum for each subsequent meeting is 50% of the outstanding shares. Action at any extraordinary general meeting may only be taken by holders of at least 50% of the outstanding shares provided, however, that a quorum of 85% and approval of at least 80% of the outstanding shares, will be required to approve the following (1) mergers, other than mergers with subsidiaries; and (2) amendment or deletion of the provision in the bylaws that regulate share ownership of the company, shareholders’ meetings and the Board of Directors.

Shareholders’ meetings may be called by the chairman of our Board of Directors, the chairman of Audit Committee or the chairman of the Corporate Practices, Finance, Planning and Sustainability Committee and must be called by any such chairman upon the written request of holders of at least 10% of our outstanding share capital. In addition, any such chairman shall call a shareholders’ meeting at the written request of any shareholder if no shareholders’ meeting has been held for two consecutive years or if the shareholders’ meetings held during such period have not considered the preceding year’s board of director’s report or our consolidated financial statements or have not the elected directors and determined their compensation. Notice of meetings must be published in a major newspaper in Mexico City. Meetings must be held in Mexico City. A proxy may represent a shareholder at a shareholders’ meeting.

Holders of 20% of our outstanding shares may oppose any resolution adopted at a shareholders’ meeting and file a petition for a court order to suspend the resolution temporarily within 15 days following the adjournment of the meeting at which the action was taken, provided that the challenged resolution violates Mexican law or our bylaws and the opposing shareholders neither attended the meeting nor voted in favor of the challenged resolution. In order to obtain such a court order, the opposing shareholder must deliver a bond to the court in order to secure payment of any damages that we may suffer as a result of suspending the resolution in the event that the court ultimately rules against the opposing shareholder. Shareholders representing at least 10% of the shares present at a shareholders’ meeting may request to postpone a vote on a specific matter on which they consider themselves to be insufficiency informed.

Dividend Rights

At the annual ordinary general meeting, our Board of Directors submits to the shareholders for their approval our consolidated financial statements and of certain of our subsidiaries. Five percent of our net earnings must be allocated to a legal reserve fund, until such fund reaches an amount equal to at least 20% of our share capital. Additional amounts may be allocated to other reserve funds as the shareholders determine. The remaining balance, if any, of net earnings may be distributed as dividends on the shares. Cash dividends on the shares will be paid against surrender to us of the relevant dividend coupon registered in the name of the holder thereof.

132

Holders of CPOs are entitled to receive the economic benefits corresponding to the shares underlying the CPOs, at the time that we declare and pay dividends or make distributions to stockholders, and to receive the proceeds of the sale of such shares at the termination of the CPO trust agreement. The CPO trustee will distribute cash dividends and other cash distributions received by it in respect of the shares held in the CPO trust to the holders of the CPOs in proportion to their respective holdings, in each case in the same currency in which they were received. Dividends paid with respect to shares underlying the CPOs will be distributed to the holders (including the depositary) on the business day on which Indeval receives the funds on behalf of the CPO trustee.

If our distribution consists of a dividend in shares, such shares will be held in the CPO trust and the CPO trustee will distribute to the holders of outstanding CPOs, in proportion to their holdings, additional CPOs in an aggregate number equal to the aggregate number of shares received by the CPO trustee as such dividend. If the maximum amount of CPOs that may be delivered under the CPO deed would be exceeded as a result of a dividend in shares, a new CPO deed would need to be entered into setting forth that new CPOs (including those CPOs exceeding the number of CPOs authorized under the CPO deed) may be issued. In the event that the CPO trustee receives any distribution with respect to shares held in the CPO trust other than in the form of cash or additional shares, the CPO trustee will adopt such method as it may deem legal, equitable and practicable to effect the distribution of such property.

If we offer or cause to be offered to the holders of shares the right to subscribe for additional shares, subject to applicable law, the CPO trustee will offer to each holder of CPOs the right to instruct the CPO trustee to subscribe for such holder’s proportionate share of such additional shares (subject to such holder’s providing the CPO trustee with the funds necessary to subscribe for such additional shares). Neither the CPO trustee nor we are obligated to register such rights, or the related shares, under the Securities Act. If the offering of rights is possible, under applicable law and without registration under the Securities Act or otherwise, and CPO holders provide the CPO trustee with the necessary funds, the CPO trustee will subscribe for the corresponding number of shares, which will be placed in the CPO trust, and deliver additional CPOs through Indeval in respect of such shares to the applicable CPO holders pursuant to the CPO deed or, to the extent possible, pursuant to a new CPO deed.

According to Mexican law, dividends or other distributions and the proceeds from the sale of the shares held in the CPO trust that are not received or claimed by a CPO holder within three years from the receipt of such dividends or distributions or ten years from such sale will become the property of the estate of the Mexican Ministry of Health.

The Bank of New York as depository, is required to convert, as soon as possible, into U.S. dollars, all cash dividends and other cash distributions denominated in Mexican pesos (or any other currency other than U.S. dollars) that it receives in respect of the deposited CPOs, and to distribute the amount received to the holders of American Depositary Receipts, or ADRs, in proportion to the number of ADSs evidenced by such holder’s ADRs without regard to any distinctions among holders on account of exchange restrictions or the date of delivery of any ADR or ADRs or otherwise. The amount distributed will be reduced by any amounts to be withheld by us, the CPO trustee and the depositary, including amounts on account of any applicable taxes and certain other expenses. If the depositary determines that in its judgment any currency other than U.S. dollars received by it cannot be so converted on a reasonable basis and transferred, the depositary may distribute such foreign currency received by it or in its discretion hold such foreign currency (without liability for interest) for the respective accounts of the ADR holders entitled to receive the same.

If we declare a dividend in, or free distribution of, additional shares, upon receipt by or on behalf of the depositary of additional CPOs from the CPO trustee, the depositary may with our approval, and shall if we so request, distribute to the holders of outstanding ADRs, in proportion to the number of ADSs evidenced by their respective ADRs, additional ADRs evidencing an aggregate number of ADSs that represents the number of CPOs received as such dividend or free distribution. In lieu of delivering ADRs for fractional ADSs in the event of any such distribution, the depositary will sell the amount of CPOs represented by the aggregate of such fractions and will distribute the net process to holders of ADRs in accordance with the deposit agreement. If additional ADRs (other than ADRs for fractional ADSs) are not so distributed, each ADS shall thereafter also represent the additional CPOs distributed in respect of the CPOs represented by such ADS prior to such dividend or free distribution.

133

Changes in Share Capital and Preemptive Rights

The fixed portion of our capital stock may only be increased or decreased by resolution of an extraordinary general meeting, whereas the variable portion of our capital stock may be increased or decreased by resolution of an ordinary general meeting.

In the event of a capital increase, each holder of existing shares has a preferential right to subscribe for a sufficient number of new shares to maintain the holder’s existing proportionate holding of shares. Preemptive rights must be exercised within 15 days after publication of a notice of the capital increase in the Official Gazette of the Federation (Diario Oficial de la Federacion) or they will lapse. Preemptive rights may not be waived in advance by a shareholder except under limited instances, and cannot be represented by an instrument that is negotiable separately from the corresponding share. Shares issued by us in connection with an increase in its variable capital, with respect to which preemptive rights have not been exercised, may be sold by us on terms previously approved by the shareholders’ meeting or the Board of Directors, but in no event below the price at which they had been offered to shareholders.

Holders of CPOs or ADSs that are U.S. persons or are located in the United States may be restricted in their ability to participate in the exercise of such pre-emptive rights.

Shares issued under Article 53 of the Mexican Securities Market Law (which are those held in treasury to be delivered upon their subscription) may be offered for subscription and payment by the Board of Directors without preemptive rights being applicable, provided that the issuance is made to effect a public offering in accordance with the Mexican Securities Market Law.

Limitations on Share Ownership

Our bylaws prohibit ownership of the shares by foreign investors. Any acquisition of shares in violation of such provision would be null and void under Mexican law and such shares would be canceled and our share capital accordingly reduced. Non-Mexican nationals may, however, hold financial interests in shares through the CPOs issued under the CPO trust.

Pursuant to our amended bylaws, significant acquisitions of shares of our capital stock and changes of control require prior approval of our Board of Directors. Our Board of Directors must authorize in advance any transfer of voting shares of our capital stock that would result in any person or group becoming a holder of 5% or more of our shares. Any acquisition of shares of our capital stock representing more than 15% of our capital stock by a person or group of persons requires the purchaser to make a public offer for the greater of:

• the percentage of shares sought, or

• 10 percent of the total shares.

If the tender offer is oversubscribed, shares sold will be allocated on a pro rata basis among the selling shareholders. If the authorized purchase of shares is for the intent of acquiring control of us, the purchaser must make an offer to purchase 100 percent of the shares.

The public offer to purchase must be made at the same price for all shares. The offer price is required to be highest of:

• the book value of the shares,

• the highest closing price on the Mexican Stock exchange during the 365 days preceding the date of the authorization, or

• the highest price paid at any time by the persons intending to purchase the shares.

134

Notwithstanding the foregoing, the Board of Directors may authorize that the public offer be made at a different price, which may be based the prior approval of the Audit Committee and an independent valuation.

These provisions shall not apply in cases of transfer of shares as a result of death, the repurchase or amortization of shares, subscription of shares in exercise of preferential rights, or by us and our subsidiaries, or by the person who maintains effective control of us.

Delisting

In the event that we decide to cancel the registration of our shares with the National Registry of Securities (Registro Nacional de Valores) or the CNBV, orders this deregistration, our shareholders who are deemed to have “control” will be required to make a tender offer to purchase the shares held by minority shareholders prior to such cancellation. Shareholders deemed to have “control” are those that own a majority of our common shares, have the ability to control our shareholders’ meetings, or have the ability to appoint a majority of the members of our Board of Directors. The price of the offer to purchase will generally be the higher of:

• the average trading price on the Mexican Stock Exchange during the last 30 days on which the shares were quoted prior to the date on which the tender offer is made; and

• the book value of the shares as reflected in our latest quarterly financial information filed with the CNBV and the Mexican Stock Exchange.

In accordance with the applicable regulations, in the event that our controlling shareholders are unable to purchase all of our outstanding shares pursuant to a tender offer, they must form a trust and contribute to it the amount required to secure payment of the purchase price offered pursuant to the tender offer to all of our shareholders that did not sell their shares pursuant to the tender offer. The trust must exist for a period of at least six months.

Controlling shareholders are not required to make a tender offer if the deregistration is approved by 95% of our shareholders. Nevertheless, the trust mechanism described in the previous paragraph still must be implemented.

Five business days prior to the commencement of the tender offer, our Board of Directors must make a determination with respect to the fairness of the terms of the offer, taking into account the rights of our minority shareholders, and disclose its opinion, which must refer to the justifications for the offer price. If the Board of Directors is precluded from making this determination as a result of a conflict of interest, the board’s resolution must be based on a fairness opinion issued by an expert selected by the Audit Committee.

Certain Minority Rights

Mexican law includes a number of minority shareholder protections. These minority protections include provisions that permit:

• holders of at least 10% of our outstanding share capital to vote (including in a limited or restricted manner) to call a shareholders’ meeting;

• holders of at least 10% of our outstanding share capital to appoint one member of our Board of Directors;

• holders of at least 5% of our outstanding share capital (represented by shares or CPOs) to bring an action against our directors, members of the Audit Committee and secretary of Board for violations of their duty of care or duty of loyalty, if

• the claim covers all of the damage alleged to have been caused by us and not merely the damage suffered by the plaintiff, and

• any recovery is for our benefit and not the benefit of the plaintiffs;

135

• holders of at least 10% of our shares who are entitled to vote (including in a limited or restricted manner) at any shareholders’ meeting to request that resolutions, with respect to any matter on which were not sufficiently informed, be postponed; and

• holders of at least 20% of our outstanding share capital to contest and suspend any shareholder resolution, subject to certain requirements under Mexican law.

Other Provisions

Duration

Our corporate existence under our bylaws is unlimited, but may be terminated by resolution of an extraordinary general meeting of shareholders.

Conflict of Interest

A shareholder must abstain from voting in a shareholders’ meeting on a transaction in which the shareholder’s interest conflicts with our interest. If the shareholder nonetheless votes, such shareholder may be liable for damages, but only if the transaction would not have been approved without the vote of such shareholder. In addition, any director who has a conflict of interest with us relating to a proposed transaction must disclose the conflict and refrain from voting on the transaction or may be liable for damages.

Appraisal Rights

Whenever a shareholders’ meeting approves a change of corporate purpose, change of nationality or restructuring from one type of corporate form to another, any shareholder who has voted against such change or restructuring has the right to withdraw and receive an amount equal to the book value of its shares (in accordance with the latest balance sheet approved by the annual ordinary general meeting), provided such shareholder exercises its right to withdraw during the 15-day period following the meeting at which such change or restructuring was approved. Because the CPO trustee is required to vote the shares held in the CPO trust in the same manner as the holders of a majority of the shares that are not held in the CPO trust and that are voted at the relevant meeting, appraisal rights will not be available to holder of CPOs.

Purchase by our Company of its Shares

We may purchase shares for cancellation pursuant to a decision of our extraordinary general meeting of shareholders. We may also repurchase shares on the Mexican Stock Exchange at the then prevailing market prices. Any such repurchase must be approved by our Board of Directors, and must be paid for using shareholders’ equity. If, however, the repurchased shares will be converted into treasury shares, we may allocate our capital toward such repurchases. The corporate rights corresponding to such repurchased shares may not be exercised during the period in which such shares are owned by us, and such shares will not be deemed to be outstanding for purposes of calculating any quorum or vote at a shareholders’ meeting during such period. The repurchased shares (including any received as dividends) must be resold on the Mexican Stock Exchange.

Purchase of Shares by Subsidiaries of our Company

Companies or other entities controlled by us may not purchase, directly or indirectly, shares or shares of companies or entities that are our shareholders.

Rights of Shareholders

The protections afforded to minority shareholders under Mexican law are different from those in the United States and many other jurisdictions. The substantive law concerning fiduciary duties of directors has not been the subject of extensive judicial interpretation in Mexico, unlike many states in the United States where duties of care and loyalty elaborated by judicial decisions help to shape the rights of minority shareholders. Mexican civil

136

procedure does not contemplate class actions or shareholder derivative actions, which permit shareholders in U.S. courts to bring actions on behalf of other shareholders or to enforce rights of the corporation itself. Shareholders cannot challenge corporate action taken at a shareholders’ meeting unless they meet certain procedural requirement, as described above under “Shareholders’ Meetings.”

As a result of these factors, in practice it may be more difficult for our minority shareholders to enforce rights against us or our directors or controlling shareholders than it would be for shareholders of a U.S. company.

In addition, under the U.S. securities laws, as a foreign private issuer we are exempt from certain rules that apply to domestic U.S. issuers with equity securities registered under the U.S. Securities Exchange Act of 1934, as amended, including the proxy solicitation rules, the rules requiring disclosure of share ownership by directors, officers and certain shareholders. We are also exempt from certain of the corporate governance requirements of the NYSE.

Enforceability of Civil Liabilities

We are organized under the laws of Mexico, and most of our directors, officers and controlling person reside outside the United States. In addition, all or a substantial portion of our subsidiaries and their assets are located in Mexico. As a result, it may be difficult for investors to effect service of process within the United States on such persons. It may also be difficult to enforce against them, either inside or outside the United States, judgments obtained against them in U.S. courts, or to enforce in U.S. courts judgments obtained against them in courts in jurisdictions outside the United States, in any action based on civil liabilities under the U.S. federal securities laws. There is doubt as to the enforceability against such persons in Mexico, whether in original actions or in actions to enforce judgments of U.S. courts, of liability based solely on the U.S. federal securities laws.

B. MATERIAL CONTRACTS

We have not entered into any material contracts, other than in the ordinary course of business for the two years immediately preceding the date of this annual report on Form 20-F.

C. EXCHANGE CONTROLS

Mexico has had a free market for foreign exchange since 1991 and the government has allowed the Mexican peso to float freely against the U.S. dollar since December 1994. We cannot assure you that the government will maintain its current foreign exchange policies. See “Item 3. Key Information—Exchange Rates.”

D. TAXATION

The following summary contains a description of the principal U.S. federal income and Mexican federal tax consequences of the purchase, ownership and disposition of CPOs or ADSs by a holder that is a citizen or resident of the United States or a U.S. domestic corporation or that otherwise will be subject to U.S. federal income tax on a net income basis in respect of the CPOs or ADSs (a “U.S. holder”), but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a decision to purchase CPOs or ADSs. In particular, the summary deals only with U.S. holders that will hold CPOs or ADSs as capital assets and does not address the tax treatment of U.S. holders that own (or are deemed to own) 10% or more of our voting shares or that may be subject to special tax rules, such as banks, insurance companies, dealers in securities or currencies, persons that will hold CPOs or ADSs as a position in a “straddle” for tax purposes and persons that have a “functional currency” other than the U.S. dollar. Further, this summary does not address the alternative minimum tax, the Medicare tax on net investment income or other aspects of U.S. federal income or state and local taxation that may be relevant to you in light of your particular circumstances.

The summary is based on tax laws of the United States and the federal income tax laws of Mexico as in effect on the date of this annual report, including the provisions of the income tax treaty between the United States and Mexico (and the protocols thereto), or the Tax Treaty, which are subject to change. Holders of CPOs or ADSs should consult their own tax advisers as to the U.S., Mexican or other tax consequences of the purchase, ownership and disposition of CPOs or ADSs, including, in particular, the effect of any foreign, state or local tax laws.

137

For purposes of this summary, the term “non-resident holder” means a holder that is not a resident of Mexico and that will not hold CPOs or ADSs or a beneficial interest therein in connection with the conduct of a trade or business through a permanent establishment in Mexico.

For purposes of Mexican taxation, a natural person is a resident of Mexico, among other circumstances, if he has established his home or his center of vital interests in Mexico. Under Mexican law, individuals are considered to have their center of vital interests in Mexico if more than 50% of their income in any calendar year is from Mexican sources, or if their main center of professional activity is located in Mexico. Natural persons that are employed by the Mexican government will be deemed to be a resident of Mexico, even if their center of vital interests is in another country. A legal entity is a resident of Mexico either if it has its principal place of business or its place of effective management in Mexico. If a non-resident has a permanent establishment in Mexico for tax purposes, all income attributable to such permanent establishment will be subject to Mexican taxes, in accordance with applicable tax laws.

In general, for U.S. federal income tax purposes, holders of ADSs or CPOs will be treated as the beneficial owners of the shares represented by those ADSs or CPOs.

Taxation of Dividends

Mexican Tax Considerations

Under Mexican income tax law, dividends, either in cash or in kind, paid to Mexican individuals and non-resident holders with respect to the shares represented by the ADSs or CPOs are subject to a 10% Mexican tax withholding (provided that no Mexican withholding tax will apply to distributions of net taxable profits generated before 2014). Non-resident holders may be subject to withholding tax at reduced rates if they are eligible for benefits under an applicable tax treaty with Mexico.

U.S. Tax Considerations

The gross amount of any dividends paid with respect to the shares represented by ADSs or CPOs (including any Mexican taxes withheld) generally will be includible in the gross income of a U.S. holder on the day on which the dividends are received by the CPO trustee (which will be the same date as the date of receipt by the Depositary) and will not be eligible for the dividends received deduction allowed to corporations under the Internal Revenue Code of 1986. Dividends, which will be paid in Mexican pesos, will be includible in the income of a U.S. holder in a U.S. dollar amount calculated by reference to the exchange rate in effect on the day they are received by the CPO trustee. U.S. holders should consult their own tax advisors regarding the treatment of foreign currency gain or loss, if any, on any Mexican pesos received that are converted into U.S. dollars on a date subsequent to receipt. Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of dividends received by an individual generally will be subject to taxation at a preferential rate if the dividends are “qualified dividends.” Dividends paid will be treated as qualified dividends if (1) the securities with respect to the which the dividends are received are readily tradable on an established securities market in the United States or we are eligible for the benefits of a comprehensive income tax treaty with the United States that the Internal Revenue Service has approved for the purposes of the qualified dividend rules and (2) we were not, in the year prior to the year in which the dividend was paid, and are not, in the year in which the dividend is paid, a passive foreign investment company, or PFIC. The ADSs are listed on the New York Stock Exchange, and will qualify as readily tradable on an established securities market in the United States so long as they are so listed. The Tax Treaty has been approved for the purposes of the qualified dividend rules. Based on our audited financial statements and relevant market and shareholder data, we believe that we were not treated as a PFIC for U.S. federal income tax purposes with respect to our 2015 taxable year. In addition, based on our audited financial statements and our current expectations regarding the value and nature of our assets, the sources and nature of our income, and relevant market and shareholder data, we do not anticipate becoming a PFIC for our 2016 taxable year.

138

The U.S. Treasury has announced its intention to promulgate rules pursuant to which holders of ADSs or ordinary stock and intermediaries through whom such securities are held will be permitted to rely on certifications from issuers to establish that dividends are treated as qualified dividends. Because such procedures have not yet been issued, it is not clear whether we will be able to comply with them. Holders of ADSs, CPOs and ordinary shares should consult their own tax advisers regarding the availability of the reduced dividend tax rate in the light of their own particular circumstances.

Dividends generally will constitute foreign source income for U.S. foreign tax credit purposes.

Distributions to holders of additional shares with respect to their ADSs or CPOs that are made as part of a pro rata distribution to all of our shareholders generally will not be subject to U.S. federal income tax.

A holder of CPOs or ADSs that is a non-U.S. holder generally will not be subject to U.S. federal income or withholding tax on dividends received, unless such income is effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States.

Taxation of Dispositions of ADSs or CPOs

Mexican Tax Considerations

Subject to applicable tax treaties, gain on the sale of CPOs by a non-resident holder will be subject to a 10% Mexican tax so long as (i) the transaction is carried out through the Mexican Stock Exchange or a securities market approved by the Mexican Ministry of Finance and Public Credit (including the NYSE) and (ii) the holder does not beneficially own and, within 24 months of the transaction, dispose of 10% or more of the capital stock of the CPO issuer. If these requirements are not met, a non-resident holder generally will be subject to Mexican tax on the sale of CPOs at a 25% rate on the gross proceeds from sale or other disposition. Alternatively, subject to certain requirements, a non-resident holder may elect to pay Mexican tax at a 35% rate on the net gain realized on the sale or disposition of its CPOs, which gain should be calculated pursuant to Mexican income tax law provisions.

Gain from the sale or disposition of ADSs (as opposed to directly held shares) by a non-resident holder generally should not be subject to Mexican withholding tax, provided that the transaction is carried out through an approved stock exchange (including the NYSE).

Under the Tax Treaty, a non-resident holder that is eligible to claim the benefits of the Tax Treaty will be exempt from Mexican tax on gains realized on a sale or other disposition of CPOs or ASDs in a transaction that is not carried out through the Mexican Stock Exchange or such other approved securities markets, so long as the holder did not own, directly or indirectly, 25% or more of our capital stock (including ADSs) within the 12-month period preceding such sale or other disposition.

U.S. Tax Considerations

Gain or loss realized by a U.S. holder on the sale or other disposition of ADSs or CPOs will be subject to U.S. federal income taxation as capital gain or loss in an amount equal to the difference between the amount realized on the disposition and such U.S. holder’s tax basis in the ADSs or the CPOs. Gain or loss realized by a U.S. holder on such sale, redemption or other disposition generally will be long-term capital gain or loss if, at the time of the disposition, the ADSs or the CPOs have been held for more than one year. The net amount of long-term capital gain recognized by an individual is taxed at a reduced rate. Deposits and withdrawals of CPOs by U.S. holders in exchange for ADSs will not result in the realization of gain or loss for U.S. federal income tax purposes.

Gain, if any, realized by a U.S. holder on the sale or other disposition of CPOs or ADSs will be treated as U.S. source income for U.S. foreign tax credit purposes. Consequently, if a Mexican withholding tax is imposed on the sale or disposition of CPOs or ADSs, a U.S. holder that does not receive significant foreign source income from other sources may not be able to derive effective U.S. foreign tax credit benefits in respect of these Mexican taxes. U.S. holders should consult their own tax advisors regarding the application of the foreign tax credit rules to their investment in, and disposition of CPOs or ADSs.

139

A non-U.S. holder of CPOs or ADSs will not be subject to U.S. federal income or withholding tax on gain realized on the sale of CPOs or ADSs, unless:

• such gain is effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States, or

• in the case of gain realized by an individual non-U.S. holder, the non-U.S. holder is present in the United States for 183 days or more in the taxable year of the sale and certain other conditions are met.

Other Mexican Taxes

There are no Mexican inheritance, gift, succession or value-added taxes applicable to the ownership, transfer or disposition of debentures, ADSs or CPOs by non-resident holders; provided, however, that gratuitous transfers of CPOs may in certain circumstances cause a Mexican federal income tax to be imposed upon the recipient. There are no Mexican stamp, issue, registration or similar taxes or duties payable by non-resident holders of debentures, ADSs or CPOs.

U.S. Backup Withholding and Information Reporting

A U.S. holder of ADSs or CPOs may, under certain circumstances, be subject to “backup withholding” with respect to certain payments to such U.S. holder, such as dividends, or the proceeds of a sale or disposition of ADSs or CPOs unless such holder (1) comes within certain exempt categories, and demonstrates this fact when so required, or (2) provides a correct taxpayer identification number, certifies that it is not subject to backup withholding and otherwise complies with applicable requirements of the backup withholding rules. Any amount withheld under these rules does not constitute a separate tax and will be creditable against the holder’s U.S. federal income tax liability. While non-U.S. holders generally are exempt from backup withholding, a non-U.S. holder may, in certain circumstances, be required to comply with certain information and identification procedures in order to prove this exemption.

Item 11. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk from changes in currency exchange rates and interest rates. From time to time, we assess our exposure and monitor our opportunities to manage these risks. We monitor our revenue and debt composition and perform market analysis to anticipate any interest rate changes.

Interest Rate Risk

Interest Rate Sensitivity Analysis Disclosure

The sensitivity analyses below are based on the assumption of an unfavorable movement of basis points in interest rates, in the amounts indicated, applicable to each category of floating-rate financial liabilities. These sensitivity analyses cover all of our indebtedness and derivative financial instruments. We calculated our sensitivity by applying the hypothetical interest rate to our outstanding debt and adjusting accordingly for debt that is covered by our derivative financial instruments for such fluctuations.

140

For the year ended December 31, 2015, a hypothetical, instantaneous and adverse change of 100, 50 and 25 basis points in the interest rate applicable to the variable rate financial liabilities, including financial derivatives only if they are held for hedging purposes, would have resulted in an additional financing expense of approximately Ps.179 million, Ps.95 million and Ps.54 million, respectively.

Qualitative Information

Interest rate risk exists principally with respect to our indebtedness that accrues interest at floating rates. At December 31, 2015, we had outstanding approximately Ps.67,617 million of indebtedness (including notes payable and after consideration of debt issuance costs), of which 47% bore interest at fixed interest rates and 53% bore interest at floating rates of interest. At December 31, 2014, we had outstanding approximately Ps.53,779 million of indebtedness (including notes payable and after consideration of debt issuance costs), of which 75% bore interest at fixed interest rates and 25% bore interest at floating rates of interest. At December 31, 2013, we had outstanding approximately Ps.39,413 million of indebtedness, of which 52% bore interest at fixed interest rates and 48% bore interest at floating rates of interest.

We have entered into cash flow hedges, including with respect to interest rate swaps (not for trading purposes), and other trading derivative instruments for the terms of some of our credit facilities with the objective of reducing the uncertainties resulting from interest rate fluctuations. See “Risk Factors—Risks Related to Our Operations—Our hedge contracts may not effectively protect us from financial market risks and may negatively affect our cash flow” and “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Derivative Financial Instruments.”

Foreign Currency Risk

Foreign Currency Sensitivity Analysis Disclosure

The sensitivity analyses below assume an instantaneous unfavorable fluctuation in exchange rates affecting the foreign currencies in which our indebtedness is denominated. These sensitivity analyses cover all of our foreign currency assets and liabilities, as well our derivative financial instruments, We calculated our sensitivity by applying the hypothetical change in the exchange rate to our outstanding debt denominated in a foreign currency and adjusting accordingly for debt that is covered by our derivative financial instruments for such fluctuation.

As of December 31, 2015, a hypothetical, instantaneous and unfavorable change in the exchange rate of 100 Mexican cents to the exchange rate applicable to our receivables, payables and debt, including derivative financial instruments not held for trading purposes (and excluding the debt hedged by instruments held for trading purposes), would have resulted in an estimated exchange loss of approximately Ps. 1,884 million based on the highest value in pesos of the debt expressed in foreign currency.

Qualitative Information

Our principal exchange rate risk involves changes in the value of the Mexican peso relative to the dollar. As of December 31, 2015, approximately 35% of our consolidated revenues and 45% of our indebtedness were denominated in foreign currencies, mainly U.S. dollars. An appreciation of the Mexican peso relative to the U.S. dollar would decrease our dollar revenues when expressed in Mexican pesos. In addition, currency fluctuations may affect the comparability of our results of operations between financial periods, due to the translation of the financial results of our foreign subsidiaries, such as Rodio Kronsa, Los Portales, San Martin and the projects under construction in Panama. The majority of revenues and expenses of Rodio Kronsa are denominated in euros, so we believe we have a natural hedge for our exposure to exchange rate risk associated with our euro-denominated contracts. Several of our subsidiaries have lesser exposure to the foreign currency risk because a higher percentage of their revenues are denominated in U.S. dollars.

At December 31, 2015 and 2014, approximately 16% and 22%, respectively, of our construction backlog was denominated in foreign currencies and approximately 8% and 13%, respectively, of our accounts receivable were denominated in foreign currencies. As of December 31, 2015 and 2014, approximately 15% and 21%, respectively,

141

of our consolidated financial assets were denominated in foreign currencies, with the balance denominated in Mexican pesos. In addition, as of December 31, 2015 and 2014, approximately 45% and 45%, respectively, of our indebtedness was denominated in foreign currencies. Decreases in the value of the Mexican peso relative to the U.S. dollar could increase the cost in Mexican pesos of our foreign currency denominated costs and expenses and, unless contracted in the same currency as the source of repayment (as is our policy), of the revenue on the related contracts. A depreciation of the Mexican peso relative to the dollar could also result in foreign exchange losses as the Mexican peso value of our foreign currency denominated indebtedness is increased, unless the source of repayment is in the same currency as the indebtedness (as is our policy). Beginning in the second half of 2008, the Mexican peso substantially depreciated against the U.S. dollar, falling 33% from July 2 to December 31, 2008. The Mexican peso stabilized in the first quarter of 2010, and continued to be stable throughout the remainder of the year. In 2011, there was a significant depreciation in the Mexican peso against the U.S. dollar, and the noon buying rate increased to Ps. 13.95 on December 30, 2011, representing a depreciation of approximately 13%. In 2014, there was a relevant depreciation in the Mexican peso against the U.S. dollar, falling 12% from June 2, 2014 to December 31, 2014. In 2015, there was a significant depreciation in the Mexican peso against the U.S. dollar, falling 16.57% % from December 31, 2014 to December 31, 2015.

A severe devaluation or depreciation of the Mexican peso may also result in disruption of the international foreign exchange markets and may limit our ability to transfer or to convert Mexican pesos into U.S. dollars and other currencies for the purpose of making timely payments of interest and principal on our U.S. dollar-denominated indebtedness or obligations in other currencies. While the Mexican government does not currently restrict, and since 1982 has not restricted, the right or ability of Mexican or foreign persons or entities to convert Mexican pesos into U.S. dollars or to transfer other currencies out of Mexico, the Mexican government could institute restrictive exchange control policies in the future. We cannot assure you that the Mexican Central Bank will maintain its current policy with respect to the peso.

We have entered into cash flow hedges, including with respect to foreign currency cash flow, for the terms of some of our long-term credit facilities with the objective of reducing the uncertainties resulting from exchange rate fluctuations. See “Risk Factors—Risks Related to Our Operations—Our hedging contracts may not effectively protect us from financial market risks and may negatively affect our cash flow” and “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources—Derivative Financial Instruments.”

The depositary of our ADSs, The Bank of New York Mellon, collects its fees directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects these fees by deducting them from the amounts distributed or by selling a portion of distributable property to pay the fees. For example, the depositary may deduct from cash distributions, directly bill investors or charge the book-entry system accounts of participants acting for them. The depositary may generally refuse to provide fee-attracting services until its fees for these services are paid.

PART II

Item 13. Defaults, Dividend Arrearages and Delinquencies

On November 30, 2015, we elected not to pay approximately US$ 31 million in interest on our Senior Notes due 2024 (“2024 Notes”), in order to preserve liquidity, prioritize ongoing operations, and fund projects currently under development. Our Company did not subsequently we did not make the payment prior to the end of the 30-day grace period provided for in the Indenture agreement for the 2024 Notes.

Item 14. Material Modifications to the Rights of Security Holders and Use of Proceeds

None.

Item 15. Controls and Procedures

(a) Disclosure Controls and Procedures

We have evaluated, with the participation of our chief executive officer and chief financial officer, the design and operation of our disclosure controls and procedures as of December 31, 2015.

There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our chief executive officer and chief financial officer have concluded that, as of December 31. 2015, our disclosure controls and procedures were not effective, due to the material weaknesses in our internal control over: (i) a deficiency in our Company’s control activities, information and communication and monitoring activities associated with the valuation of deferred tax assets related to net loss carry forward, and (ii) deficiencies in our Company’s control activities, information and communication, and monitoring activities in our Civil Construction segment.

145

(b) Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities and Exchange Act of 1934. For the year ended December 31, 2015, our financial statements were prepared in accordance with the International Financial Reporting Standards, or IFRS, issued by the International Accounting Standards Board. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards. Our internal control over financial reporting includes those policies and procedures that:

(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;

(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with IFRS, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

(3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate. Under the supervision of our Chief Executive Officer and Chief Financial Officer, our management assessed the design and effectiveness of our internal control over financial reporting as of December 31, 2015. In making its assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, in Internal Control – Integrated Framework (2013).

Our management identified material weaknesses in our internal control as described above.

As a result of these material weaknesses, we concluded that our internal control over financial reporting was not effective as of December 31, 2015.

Galaz, Yamazaki, Ruiz Urquiza, S.C. a member of Deloitte Touche Tohmatsu Limited, the independent registered public accounting firm that has audited our consolidated financial statements, has issued an attestation report on the effectiveness of our internal control over financial reporting.

146

(c) Management’s Remediation Plans and Activities

To address the material weaknesses we have identified, we have added the task of preparing a risk analysis of the material weaknesses to the Audit Committee’s agenda. These material weaknesses arose during the restructuring process of our Company and our Audit Committee along with our Company management are defining a remediation plan to be implemented immediately.

(d) Report of Independent Registered Public Accounting Firm on Internal Control over Financial Reporting

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Empresas ICA, S.A.B. de C.V.

We have audited the accompanying consolidated statements of financial position of Empresas ICA, S.A.B. de C.V. and subsidiaries (the “Entity”) as of December 31, 2015, 2014 and 2013, and the related consolidated statements of results and other comprehensive (loss) income, changes in stockholders’ equity, and of cash flows for each of the three years in the period ended December 31, 2015. Our audits also included the financial statement schedules listed in the Index in Item 18. These consolidated financial statements and financial statement schedules are the responsibility of the Company’s management. Our responsibility is to express an opinion on the consolidated financial statements and financial statement schedules based on our audits. We also have audited the Entity’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Entity’s management is responsible for these consolidated financial statements, for the financial statement schedules listed in the Index at Item 18, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Item 15(b) Management’s Annual Report on Internal Control over Financial Reporting of the 2015 Form 20-F. Our responsibility is to express an opinion on these consolidated financial statements, the financial statement schedules and an opinion on the Entity’s internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the financial reporting standards used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with International Financial Reporting Standards and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

147

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Entity’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in management’s assessment: (i) a deficiency in the Entity’s control activities, information and communication, and monitoring activities associated with the valuation of deferred tax assets related to net loss carryforwards, and (ii) deficiencies in the Entity’s control activities, information and communication, and monitoring activities at its civil construction segment. These material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the consolidated financial statements as of and for the year ended December 31, 2015, of the Entity and this report does not affect our report on such financial statements.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Empresas ICA, S.A.B. de C.V. and subsidiaries as of December 31, 2015, 2014 and 2013, and the results of their operations and other comprehensive (loss) income and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also, in our opinion, such financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein. Additionally, in our opinion, because of the effect of the material weaknesses identified above on the achievement of the objectives of the control criteria, the Entity has not maintained effective internal control over financial reporting as of December 31, 2015, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We do not express an opinion or any other form of assurance on management statements regarding remediation activities contained in Item 15(b) Management’s Annual Report on Internal Control over Financial Reporting of the 2015 Form 20-F.

The accompanying consolidated financial statements as of and for the year ended December 31, 2015 have been prepared assuming that the Entity will continue as a going concern. As discussed in Notes 2 and 27 to the consolidated financial statements, the Entity is experiencing recurring net losses and as of December 31, 2015 has an excess of current liabilities over current assets and failed to make a certain required interest payments. These circumstances raise substantial doubt about the Entity’s ability to continue as a going concern. Management’s plans concerning these matters are also discussed in Note 2 to the consolidated financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Our audits also comprehended the translation of Mexican peso amounts into U.S. dollar amounts and, in our opinion, such translation has been made in conformity with the basis stated in Note 3.c to the consolidated financial statements. Such U.S. dollar amounts and the translation of the financial statements into English are presented solely for the convenience of readers outside Mexico.

Item 16G. Corporate Governance

NYSE Corporate Governance Comparison

Pursuant to Section 303A.11 of the Listed Company Manual of the NYSE, we are required to provide a summary of the significant ways in which our corporate governance practices differ from those required for U.S. companies under the NYSE listing standards. We are a Mexican corporation with shares listed on the Mexican Stock Exchange. Our corporate governance practices are governed by our bylaws, the Mexican Securities Market Law and the regulations issued by the Mexican National Banking and Securities Commission. We also comply on a voluntary basis with the Mexican Code of Best Corporate Practices (Codigo de Mejores Practicas Corporativas) as indicated below, which was created in January 2001 by a group of Mexican business leaders and was endorsed by the Mexican Banking and Securities Commission. On an annual basis, we file a report with the Mexican Banking and Securities Commission and the Mexican Stock Exchange regarding our compliance with the Mexican Code of Best Corporate Practices.

150

The table below discloses the significant differences between our corporate governance practices and the NYSE standards.

NYSE Standards	Our Current Corporate Governance Practices
A majority of board of directors must be independent. §303A.01	Pursuant to the Mexican Securities Market Law and our bylaws, our shareholders are required to appoint a Board of Directors of between five and twenty-one members, 25% of whom must be independent within the meaning of the Mexican Securities Market Law, which differs from the definition of independent under the rules of the New York Stock Exchange.
	Our Board of Directors currently consists of twelve members, of which nine are outside (i.e. non-management) directors. Seven of our directors are independent directors within the meaning of the Mexican Securities Market Law and within the meaning of Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act.
	Pursuant to our bylaws board members must be appointed based on their experience, ability and professional prestige. Our Board of Directors must meet at least every three months.
A director is not independent if such director is:	Under Article 26 is of the Mexican Securities Market Law, a director is not independent if such director is:
(i) a person who the board determines has a material direct or indirect relationship with the listed company;	(i) or has been within the last year, an employee or officer of the company;
(ii) or has been within the last three years, an employee, or an immediate family member of an executive officer, of the listed company, other than employment as interim chairman or CEO;	(ii) a shareholder that, without being an employee or officer of the company, has influence or authority over the company’s officers;
(iii) or has been within the last three years, a person who receives, or whose immediate family member receives, more than $ 120,000 during any 12-month period in direct compensation from the listed company, other than director and committee fees and pension or other deferred compensation for prior service (and other than compensation for service as interim chairman or CEO or received by an immediate family member for service as a non-executive employee);	(iii) a partner or employee of a consultant or adviser, to the company or its affiliates, where the income from the company represents 10% or more of the overall income of such consultant or adviser;
(iv) a person who is, or whose immediate family member is, or has been within the last three years, a partner or employee of an internal or external auditor of the listed company, subject to limited exceptions for persons who did not personally work on the listed company’s audit in the last three years;	(iv) an important client, supplier, debtor or creditor (or a partner, director or employee thereof). A client and supplier is considered important when its sales to or purchases from the company represent more than 10% of the client’s or supplier’s total sales or purchases. A debtor or creditor is considered important whenever the aggregate amount of the relevant loan represents more than 15% of the debtor’s, creditor’s or the company’s aggregate assets;

151

NYSE Standards	Our Current Corporate Governance Practices
(v) an executive officer, or an immediate family member of an executive officer, of another company where any of the listed company’s present executive officers at the same time serves or served on that company’s compensation committee; or
(vi) an executive officer or employee of a company, or an immediate family member of an executive officer of a company, that has made payments to, or has received payments from, the listed company, its parent or a consolidated subsidiary for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $ 1 million or 2% of such other company’s consolidated gross revenues (except for contributions to tax-exempt organizations provided that the listed company discloses such contributions in the company’s proxy statement or annual report)
“Immediate family member” includes a person’s spouse, parents, children, siblings, mothers and fathers-in-law, sons and daughters-in-law and anyone (other than domestic employees) who shares the person’s home. Individuals who are no longer immediate family members due to legal separation, divorce or death (or incapacity) are excluded. §303A.02(b)	(v) a “family member” related to any of the persons mentioned above in (i) through (iv). “Family member” includes a person’s spouse, concubine or other relative up to the fourth degree of consanguinity and affinity, as well as a spouse or concubine of the individuals mentioned above.
“Company” includes any parent or subsidiary in a consolidated group with the listed company.
Non-management directors must meet regularly in executive sessions without management. Independent directors should meet alone in an executive session at least once a year. §303A.03	There is no similar requirement under our bylaws or applicable Mexican law.
A listed company must have a nominating/corporate governance committee of independent directors. The committee must have a charter specifying the purpose, minimum duties and evaluation procedures of the committee. §303A.04	We are required to have a corporate practices committee pursuant to the provisions of the Mexican Securities Market Law and our bylaws. Our bylaws require that the Corporate Practices Committee be composed of independent directors within the meaning of the Mexican Securities Market Law. The duties of our Corporate Practices Committee include:
	•      providing an opinion on the nomination of the members of the Board of Directors, •      providing an opinion on the nomination of the chief executive officer,
	•      assessing the performance of our senior management,
	•      providing an opinion on related party transactions,
	•      providing an opinion on compensation proposals for senior management, and

152

NYSE Standards	Our Current Corporate Governance Practices
	•      reviewing certain exempted actions of the Board of Directors.
A listed company must have a compensation committee composed entirely of independent directors, which must approve executive officer compensation. The committee must have a charter specifying the purpose, minimum duties and evaluation procedures of the committee. §303A.05	The Corporate Practices Committee provides an opinion on compensation proposals for the Chief Executive Officer and other executive officers pursuant to the provisions of the Mexican Securities Market Law.
	Our Corporate Practices Committee makes recommendations as to compensation for senior and middle management to the Board of Directors, which must approve such recommendations.
A listed company must have an audit committee satisfying the independence and other requirements of Rule 10A-3 under the Exchange Act and the more stringent requirements under the NYSE standards. §§303A.06, 303A.07	We have a three-member Audit Committee, which is composed of independent directors appointed by our board. The Mexican Securities Market Law requires that our shareholders appoint the president of our Audit Committee. Currently all members of our Audit Committee are independent as such term is defined under the Mexican Securities Market Law and under Rule 10A-3 under the Exchange Act.
	However, the members of our Audit Committee are not required to satisfy the NYSE independence and other audit committee standards that are not prescribed by Rule 10A-3.
	Our Audit Committee complies with the requirements of the Mexican Securities Market Law and has the following attributes:
	•      Our Audit Committee operates pursuant to a written charter adopted by the Audit Committee and approved by our Board of Directors.
	•      Pursuant to our bylaws and Mexican law, our Audit Committee submits an annual report regarding its activities to our Board of Directors.
	•      The duties of the Audit Committee include:
	•      periodically evaluating our internal control to oversee our internal auditing and control systems;
	•      periodically evaluating our internal control mechanisms;
	•      recommending independent auditors to our Board of Directors;

153

NYSE Standards	Our Current Corporate Governance Practices
	•      establishing procedures for the confidential, anonymous submission by employees of concerns regarding questionable accounting or auditing matters controls;
	•      hiring independent counsel and other advisors as it deems necessary to carry out its duties, including the review of related-party transactions; and
	•      overseeing the performance of our outside auditor.
Equity compensation plans and material revisions thereto require shareholder approval, subject to limited exemptions. §303A.08	In accordance with Mexican law, our shareholders have approved our existing equity compensation plans at shareholder meetings, which plans are carried out by the board with respect to our executives.
A listed company must adopt and disclose corporate governance guidelines and a code of business conduct and ethics for directors, officers and employees, and promptly disclose any waiver for directors or executive officers within four business days of such determination. §§303A.09, 303A.10	We have adopted a code of ethics, which has been accepted by all of our directors and executive officers and other personnel. We are required by Item 16B of this Form 20-F to disclose any waivers granted to our chief executive officer, chief financial and accounting officer and persons performing similar functions.
The CEO must certify to the NYSE each year that he or she is not aware of any violation by the company of NYSE corporate governance listing standards and must promptly notify the NYSE in writing after any executive officer becomes aware of any non-compliance with the NYSE corporate governance listing standards. §303A.12	Our CEO will promptly notify the NYSE in writing if any executive officer becomes aware of any material noncompliance with any applicable provisions of the NYSE corporate governance rules.

Report of Independent Registered Public Accounting Firm to the Board of Directors and Stockholders of Empresas ICA, S. A. B. de C. V.

We have audited the accompanying consolidated statements of financial position of Empresas ICA, S.A.B. de C.V. and subsidiaries (the “Entity”) as of December 31, 2015, 2014 and 2013, and the related consolidated statements of results and other comprehensive (loss) income, changes in stockholders’ equity, and of cash flows for each of the three years in the period ended December 31, 2015. Our audits also included the financial statement schedules listed in the Index at Item 18. These consolidated financial statements and financial statement schedules are the responsibility of the Company’s management. Our responsibility is to express an opinion on the consolidated financial statements and financial statement schedules based on our audits. We also have audited the Entity’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Entity’s management is responsible for these consolidated financial statements, for the financial statement schedules listed in the Index at Item 18, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Item 15(b) Management´s Annual Report on Internal Control over Financial Reporting of the 2015 Form 20-F. Our responsibility is to express an opinion on these consolidated financial statements, the financial statement schedules and an opinion on the Entity’s internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the financial reporting standards used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with International Financial Reporting Standards and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

F-4

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Entity’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in management’s assessment: (i) a deficiency in the Entity’s control activities, information and communication, and monitoring activities associated with the valuation of deferred tax assets related to net loss carryforwards, and (ii) deficiencies in the Entity’s control activities, information and communication, and monitoring activities at its civil construction segment. These material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the consolidated financial statements as of and for the year ended December 31, 2015, of the Entity and this report does not affect our report on such financial statements.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Empresas ICA, S.A.B. de C.V. and subsidiaries as of December 31, 2015, 2014 and 2013, and the results of their operations and other comprehensive (loss) income and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also, in our opinion, such financial statement schedules, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein. Additionally, in our opinion, because of the effect of the material weaknesses identified above on the achievement of the objectives of the control criteria, the Entity has not maintained effective internal control over financial reporting as of December 31, 2015, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We do not express an opinion or any other form of assurance on management statements regarding remediation activities contained in Item 15(b) Management’s Annual Report on Internal Control over Financial Reporting of the 2015 Form 20-F.

The accompanying consolidated financial statements as of and for the year ended December 31, 2015 have been prepared assuming that the Entity will continue as a going concern. As discussed in Notes 2 and 27 to the consolidated financial statements, the Entity is experiencing recurring net losses and as of December 31, 2015 has an excess of current liabilities over current assets and failed to make a certain required interest payments. These circumstances raise substantial doubt about the Entity’s ability to continue as a going concern. Management’s plans concerning these matters are also discussed in Note 2 to the consolidated financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Our audits also comprehended the translation of Mexican peso amounts into U.S. dollar amounts and, in our opinion, such translation has been made in conformity with the basis stated in Note 3.c to the consolidated financial statements. Such U.S. dollar amounts and the translation of the financial statements into English are presented solely for the convenience of readers outside Mexico.

Notes to Consolidated Financial Statements

For the years ended December 31, 2015, 2014 and 2013

(Thousands of Mexican pesos, except as otherwise indicated)

1. Nature of business

Empresas ICA, S.A.B. de C.V.and subsidiaries (“ICA” or, together with its subsidiaries, the Entity”) is a holding company incorporated in Mexico with over 68 years experience, the subsidiaries of which are engaged in a wide range of construction and related activities including the construction of infrastructure facilities as well as industrial, urban and housing construction, for both the Mexican public and private sectors. ICA’s subsidiaries are also involved in the construction, maintenance and operation of highways, bridges and tunnels granted by the Mexican government and foreign governments under concessions. Through its subsidiaries, the Entity also manages and operates airports. In addition, some of ICA’s subsidiaries are engaged in real estate and housing development. Through its associated entities, since 2012, ICA provided mining related services, such as exploration and exploitation of deposits for others, transportation and other mining-related activities. ICA’s shares are traded on the Mexican Stock Exchange and the New York Stock Exchange, see Note 42. Its registered address is 36 Boulevard Manuel Avila Camacho, Piso 15, Lomas de Chapultepec, 11000 Mexico, D. F.

2. Significant events

a. Going concern

During December 2015, the Entity defaulted on the U.S.$31 million interest payment on its U.S.$700 million Senior Notes maturing in 2024. Subsequent to year end, the Entity also defaulted on U.S.$22 million and U.S.$6 million in interest payments on its U.S.$500 million Senior Notes maturing in 2021 and its U.S.$150 million Senior Notes, maturing in 2017, respectively.

The Entity’s failure to pay the interest on these Senior Notes resulted in cross-defaults of certain other long-term debt in December 2015 and subsequently in 2016, which resulted in the guarantees existing under those secured loans being executed by the respective bank creditors during the first quarter of 2016. See footnote 42. These loans, together with the obligations of the Senior Notes, are presented in current liabilities at December 31, 2015, in the Entity’s consolidated statement of financial position (see Notes 27 and 42). Additionally, the Entity has experienced a general delay in payments to certain service suppliers and creditors and taxes, as well as a reduction of operations and personnel adjustments.

At December 31, 2015, short-term liabilities exceed current assets by Ps.25.7 billion pesos and the Entity has a stockholders’ deficit, with respect to equity held by controlling interests, of Ps.3.0 billion pesos. Additionally, the Entity has suffered net losses of Ps.19.8 million and Ps.2.0 million during the last two years. These events and results raise substantial doubt about the Entity’s ability to continue as a going concern. The accompanying financial statements have been prepared under the assumption that the Entity will continue as a going concern, which assumes the realization of its assets and the settlement of its liabilities and obligations in the normal course of business. Consequently, the accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Management is considering various options, including negotiations with its current bondholders and certain suppliers in an effort to restructure its debt and other obligations as well as seek additional financing. Additionally, the Entity is analyzing the feasibility of the sale of certain assets, which are not strategic for the Entity’s operation, or the partial realization of investments to allow the Entity to obtain access to resources over the coming months. Moreover, the Entity has implemented a series of operating restructuring measures, including a reduction of personnel costs, appointment of a Restructuring

F-13

Director, changes involving key management personnel, and the creation of trusts to ensure the adequate utilization of funds assigned to certain construction projects. The Entity has hired external advisors to advise the Entity on the best restructuring strategy based on the Entity’s finances, liquidity requirements, payment capacity and operations.

Although the Entity’s management is focused on making its operations profitable, concluding and executing its restructuring plan and obtaining new financing sources, the outcome of the restructuring process and the implications it may have for parties with an interest in the Entity, such as its stockholders, creditors, suppliers, customers and employees, cannot be guaranteed, nor can the successful outcome of the restructuring plan be assured.

b. Summary of reserves and asset impairments

During 2015, the Entity recorded reserves, asset impairments, and provisions, for an amount of Ps.10,802, comprised as follows:

	December 31, 2015
Allowance for current doubtful, including costs and estimated earnings in excess of billings (Note 7.a)	Ps.	3,927,443
Allowance for long-term doubtful accounts, including costs and estimated earnings in excess of billing (Note 7.c)		1,453,762

c. Divestitures of subsidiaries

San Martín

During 2012, ICA acquired the business of San Martín Contratistas Generales, S.A. (“San Martín”). At December 31, 2014, the balance of the consideration payable was U.S.$46.4 million, equivalent to Ps. 683,741; the liability would have been payable as follows (i) U.S.$33.8 million in June 2015 and (ii) U.S.$12.6 million in May 2016. The Entity did not make the complete payment in June 2015, resulting in the immediate payment requirement of total liability. However, the Entity negotiated with the seller to make a partial payment and extend the date for payment of the remaining amount. Notwithstanding such negotiations, on October 19, 2015, the Entity received formal notification of default and on October 22, 2015, the following agreements were signed for the settlement of the liability: (i) in lieu of payment, the Entity delivered to another shareholder, shares of San Martin equivalent to 19.98% of the shares of San Martin, thereby reducing the Entity’s investment to 31.2%; (ii) the Entity assigned to another shareholder the legal right to receive dividends related to the shares of San Martín transferred up to U.S. $3 million; and (iii) a new shareholder agreement was signed, where the relevant operating decisions and the integration of the Board of Directors of San Martin will be in favor of another shareholder.

As a result of the above, as of October 2015, ICA lost control of San Martin. Accordingly, as of such date, San Martín was deconsolidated the remaining investment held by ICA in San Martin was revalued to its fair value and recognized as an investment in associated entity with a balance of Ps. 630,212 at December 31, 2015, which included the fair value of the investment at the date of loss of control, plus the equity method corresponding to the third quarter of 2015.

d. ICA OVT, sale of non-controlling interest

In April 2015, ICA signed a partnership agreement with Caisse de Dépôt et Placement du Québec (“CDPQ”), one of the leading fund managers in Canada. The agreement provides for the formation of a business that initially includes four highway concessions: ICA San Luis, S.A. de C.V., Libramiento ICA La Piedad, S.A. de C.V., Consorcio del Mayab, S.A. and Acapulco Tunnel, S.A. de C.V., indirect subsidiaries of the Entiy.

For this purpose, ICA Operadora de Vías Terrestres, S.A.P.I. de C.V. (“ICA OVT”) was created in March 2015, as a spin-off of Controladora de Operaciones de Infraestructura, S.A. de C.V. (“CONOISA”), a subsidiary of ICA. ICA OVT is the direct holder of the shares of the aforementioned concession entities, for which a series of administrative actions to achieve this objective were carried out. In May 2015, the competent governmental authorities approved the conditions precedent for the operation. In June 2015, ICA sold 49% its ownership interest in ICA OVT to CDPQ, for consideration of $3,014 million, which generated a gain, net of tax, of Ps.196 million. The gain is presented in retained earnings in the statement of changes in stockholders’ equity as control of ICA OVT was maintained and the transaction is considered a transaction between shareholders.

The financial statements of ICA OVT continue to be consolidated in the accompanying consolidated financial statements as ICA continues to maintain control over the entity with a 51% ownership in its equity. See Note 17.

e. Reversal of discontinued operations presented

On January 22, 2014, an agreement between CONOISA and Hunt Companies, Inc., American Company, was formalized, for the possible acquisition of the 70% of shareholding of CONOISA in Sarre Infraestructura y Servicios, S.A. de C.V. (“Sarre”) and Papagos Servicios Para la Sociedad, S.A. de C.V. (“Papagos”). Both entities are part of the concessions segment. The consideration for the sale of the shares was fixed at Ps.1,511 million, which was to be paid on the closing date, and was subject to the fulfillment of the terms and conditions of the agreement.

The agreement considered obtaining authorization from the Ministry of Public Security (the “Secretary”), given that Sarre and Pápagos are concession holders for the provision of correctional services in a contract executed with the Secretary. At the end of the period specified in the agreement, the Secretary did not provide its authorization for the transaction, based on the conditions of the sales transaction with Hunt. Consequently, in December 2014, the sales agreement between the Entity and Hunt was terminated.

After the withdrawal of the buyer, the Entity’s management had continued carry out formal actions to sell the assets of Sarre and Papagos. During 2015, as a result of not executing a formal sale proposal, the Entity’s management decided to forego its intention to sell such assets.

Additionally, the assets and liabilities that were classified as held for sale in the consolidated statement of financial position at December 31, 2014 and 2013 were reclassified into their respective line items in such statements.

3. Basis of presentation and consolidation

a. Statement of compliance

The consolidated financial statements have been prepared in accordance with IFRS, including its amendments and interpretations, as issued by the International Accounting Standards Board (“IASB”).

b. Basis of measurement

The consolidated financial statements have been prepared on the historical cost basis except for the revaluation of investment property and financial instruments at fair value, and certain real estate inventory which is recorded at fair value as referred to in Note 10.c and d.

i. Historical cost

Historical cost is generally based on the fair value of the consideration given in exchange for goods and services.

ii. Fair value

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, regardless of whether that price is directly observable or estimated using another valuation technique. In estimating the fair value of an asset or a liability, the Entity takes into account the characteristics of the asset or liability if market participants would take those characteristics into account when pricing the asset or liability at the measurement date. Fair value for measurement and/or disclosure purposes in these consolidated financial statements is determined on such a basis, except for share-based payment transactions that are within the scope of IFRS 2, leasing transactions that are within the scope of lAS 17, and measurements that have some similarities to fair value but are not fair value, such as net realizable value in lAS 2 or value in use in lAS 36.

In addition, for financial reporting purposes, fair value measurements are categorized into Level 1, 2 or 3 based on the degree to which the inputs to the fair value measurements are observable and the significance of the inputs to the fair value measurement in its entirety, which are described as follows:

• Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date;

• Level 2 inputs are inputs, other than quoted prices included within Level 1, that are observable for the asset or liability, either directly or indirectly; and

• Level 3 inputs are unobservable inputs for the asset or liability.

c. Convenience translation

Solely for convenience of readers, peso amounts included in the consolidated financial statements as of December 31, 2015 and for the year then ended have been translated into U.S. dollar amounts at

F-22

exchange rate of Ps.17.3398 pesos per U.S. dollar, as published by Banco de Mexico, S.A. Such translation should not be construed as a representation that the Mexican peso amounts have been, could have been or could, in the future, be converted into U.S. dollars at such rate or any other rate.

d. Reporting currency

The Mexican peso, legal currency of the United Mexican States is the currency in which the consolidated financial statements are presented. Transactions in currencies other than the peso are recorded in accordance with established policies described in Note 4.c and t.

e. Consolidated statements of results and other comprehensive (loss) income

The Entity chose to present the consolidated statement of results income and other comprehensive (loss) income in a single statement, including separate lines for gross profit and operating income, in accordance with practices of the industry. Costs and expenses were classified according to their function due to different economic activities and businesses of the Entity. Additional information regarding depreciation expense, amortization expense and employee benefits are presented in Note 35.c. Gross profit is calculated based on the sum of construction revenues, concession revenues and sales of assets and other, less their respective costs.

f. Principles of consolidation

The consolidated financial statements incorporate the financial statements of the Entity and the entities controlled by the Entity. Control is achieved when the Entity:

• has power over the investee;

• is exposed, or has rights, to variable returns from its involvement with the investee; and

• has the ability to use its power to affect its returns.

The Entity reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above.

When the Entity has less than a majority of the voting rights of an investee, it has power over the investee when the voting rights are sufficient to give it the practical ability to direct the relevant activities of the investee unilaterally. The Entity considers all relevant facts and circumstances in assessing whether or not the Entity’s voting rights in an investee are sufficient to give it power, including:

• the size of the Entity’s holding of voting rights relative to the size and dispersion of holdings of the other vote holders;

• potential voting rights held by the Entity, other vote holders or other parties;

• rights arising from other contractual arrangements; and

• any additional facts and circumstances that indicate that the Entity has, or does not have, the current ability to direct the relevant activities at the time that decisions need to be made, including voting patterns at previous shareholders’ meetings.

Consolidation of a subsidiary begins when the Entity obtains control over the subsidiary and ceases when the Entity loses control of the subsidiary. Specifically, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated statement of results and other comprehensive income (loss) from the date the Entity gains control until the date when the Entity ceases to control the subsidiary.

Net profit or loss and each component of other comprehensive (loss) income are attributed to the owners of the Entity and to the non-controlling interests. Total comprehensive income of subsidiaries is attributed to the owners of the Entity and to the non-controlling interests even if this results in the non-controlling interests having a deficit balance.

F-23

The non-controlling interests in equity of subsidiaries are presented separately as non-controlling interests in the consolidated statements of financial position, within the stockholders’ equity section, and the consolidated statements of results and other comprehensive (loss) income.

If is necessary, adjustments to the financial statements of subsidiaries are made to align its accounting policies in accordance with the accounting policies of the Entity.

The financial statements of companies that are included in the consolidation are prepared as of December 31 of each year.

All intra-group transactions, balances, income and expenses are eliminated in full on consolidation.

Note 44 includes the subsidiaries consolidated by ICA as well as information related thereto.

Changes in ICA’s ownership in subsidiaries

Changes in the Entity’s ownership interests in subsidiaries that do not result in the Entity losing control over the subsidiaries are accounted for as equity transactions. The carrying amounts of the Entity’s interests and the non-controlling interests are adjusted to reflect the changes in their relative interests in the subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in equity and attributed to owners of the Entity.

When ICA loses control of a subsidiary, a gain or loss is recognized in profit or loss and is calculated as the difference between (i) the aggregate of the fair value of the consideration received and the fair value of any retained interest and (ii) the previous carrying amount of the assets (including goodwill), and liabilities of the subsidiary and any non-controlling interests. The amounts previously recognized in other comprehensive income and accumulated in equity are accounted for as if the Entity had directly disposed of the relevant assets (i.e. they are reclassified to profit or loss or transferred directly to retained earnings as specified by applicable IFRS). The fair value of any investment retained in the former subsidiary at the date when control is lost is regarded as the fair value on initial recognition for subsequent accounting under IAS 39, Financial Instruments: Recognition and Measurement (“IAS 39”) or, when applicable, the cost on initial recognition of an investment in an associate or a jointly controlled entity.

The results of subsidiaries acquired or divested during the year are included in the consolidated statement of results and other comprehensive income (loss) from the acquisition date or the date of divestiture, as applicable.

g. Business combination

On April 2014, ICA acquired Facchina Construction Company, Inc. (“Facchina”) which was recorded using the acquisition method. The results of the acquired business were included in the consolidated financial statements from the acquisition date. Business acquired is as follows:

	Principal activity	Date of acquisition	Proportion of voting equity interest acquired	Consideration transferred
Facchina Construction Company, INC (“Facchina”) (1)	Construction services	April 14, 2014	100%	Ps.	1,151,609

(1) Facchina is a construction company which provides service in the metropolitan area of Washington. Its main offices are located in La Plata, MD, USA, providing construction services mainly to the greater

F-24

Washington area, Baltimore, Northern Virginia, Southern Maryland and Florida. The purchase price consists of an initial payment of U.S$59.3 million; during August as a result of certain negotiations, the initial payment was reduced by U.S$5 million, and contingent consideration was established based on a formula that considers achieving certain EBITDA margin levels for the years 2014 to 2019, to be paid over the next five years. The maximum amount payable for this acquisition is U.S.$95 million.

This transaction represents a significant increase in international sales of the Entity. Facchina has a business model that coincides with ICA; both operate in markets with high growth potential, ICA adds value with their experience in concessions, in which the United States is preparing a significant portfolio of Public Private Partnerships.

The characteristics of the consideration of Facchina are:

• The maximum amount of the contingent consideration will be U.S.$40 million; this can only be achieved in the first three years (initial period of payment of the contingent consideration).

• Calculation periods of contingent consideration will begin April 2014 and end on whichever occurs first: the maximum amount established of U.S.$40 million or March 31, 2017.

• Contingent consideration will be 60% of EBITDA achieved in the calculation period.

• If the amount of US $ 40 million is not reached, and the accumulated amount is less than U.S.$35 million, the period is extended another two years.

Impact of acquisitions on the financial information of the Entity

Below is consolidated pro forma financial information of ICA, considering results as if the acquisition of Fachina had occurred on January 1, 2014. This pro-forma information does not necessarily represent the actual results of operations of ICA if the acquisitions had occurred as of such date. ICA’s

F-26

Management considers these pro forma numbers to represent an approximate measure of the performance of the combined group on an annualized basis and to provide a reference point for comparison in future periods. Condensed financial information is as follows:

Consolidated statements of income and other comprehensive income:

In determining the pro forma’ revenue and profit of ICA, if had Facchina been acquired in January, 2014, the Entity has:

• Calculated depreciation of plant and equipment acquired on the basis of the fair values arising in the initial accounting for the business combination rather than the carrying amounts recognized in the pre-acquisition financial statements;

• Calculated borrowing costs on the funding levels, credit ratings and debt/equity position of the Entity after the business combination

F-27

4. Significant accounting policies

The consolidated financial statements are prepared in accordance with IFRS. Preparation of financial statements under IFRS requires management of the Entity to make certain estimates and use assumptions to value certain of the items in the consolidated financial statements as well as their related disclosures required therein. The areas with a high degree of judgment and complexity or areas where assumptions and estimates are significant in the consolidated financial statements are described in Note 5. The estimates are based on information available at the time the estimates are made, as well as the best knowledge and judgment of management based on experience and current events. However, actual results could differ from those estimates. The Entity has implemented control procedures to ensure that its accounting policies are appropriate and are properly applied. Although actual results may differ from those estimates, the Entity’s management believes that the estimates and assumptions used were adequate under the circumstances.

The consolidation requirements, accounting policies and valuation methods used in preparing the consolidated financial statements as of and for the year ended December 31, 2015 are the same as those applied in the consolidated financial statements for 2014 and 2013, except for the standards and interpretations described in paragraph a) (i) included below, which are effective in 2015.

a. Application of new and revised IFRS

i) Effective January 1, 2015, the Entity adopted the following International Financial Reporting Standards and interpretations in its consolidated financial statements:

– Amendments to IAS 19, Defined Benefit Plans: Employee Contributions

– Annual Improvements to IFRSs, 2010-2012 Cycle

– Annual Improvements to IFRSs, 2011-2013 Cycle

The Entity does not provide contributions to its defined benefit plans. Therefore, the application of Amendments to IAS 19 has had no impact on the disclosures or the amounts recognized in the consolidated financial statements. Also the application of IFRS Annual Improvements to the 2010-2012 and 2011-2013 cycle did not have a significant impact on the consolidated financial statements.

ii) The Entity has not applied the following new and revised IFRSs that have been issued but are not yet effective:

– IFRS 9, Financial Instruments (“IFRS 9”) ⁽³⁾

– IFRS 15, Revenue from Contracts with Customers ⁽³⁾

– IFRS 16, Leases ⁽⁴⁾

– Amendments to IFRS 11, Accounting for Acquisitions of Interests in Joint Operations ⁽¹⁾

IFRS 9 Financial Instruments

IFRS 9 issued in November 2009 introduced new requirements for the classification and measurement of financial assets. IFRS 9 was subsequently amended in October 2010 to include requirements for the classification and measurement of financial liabilities and for derecognition, and in November 2014 to include the new requirements for general hedge accounting. Another revised version of IFRS 9 was issued in July 2014 mainly to include a) impairment requirements for financial assets and b) limited amendments to the classification and measurement requirements by introducing a ‘fair value through other comprehensive income’ (FVTOCI) measurement category for certain simple debt instruments.

Key requirements of IFRS 9:

• All recognized financial assets that are within the scope of IAS 39 Financial Instruments: Recognition and Measurement are required to be subsequently measured at amortized cost or fair value. Specifically, debt investments that are held within a business model whose objective is to collect the contractual cash flows, and that have contractual cash flows that are solely payments of principal and interest on the principal outstanding are generally measured at amortized cost at the end of subsequent accounting periods. Debt instruments that are held within a business model whose objective is achieved both by collecting contractual cash flows and selling financial assets, and that have contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding, are measured at FVTOCI. All other debt investments and equity investments are measured at their fair value at the end of subsequent accounting periods. In addition, under IFRS 9, entities may make an irrevocable election to present subsequent changes in the fair value of an equity investment (that is not held for trading) in other comprehensive income, with only dividend income generally recognized in profit or loss.

• With regard to the measurement of financial liabilities designated as at fair value through profit or loss, IFRS 9 requires that the amount of change in the fair value of the financial liability that is attributable to changes in the credit risk of that liability is presented in other comprehensive income, unless the recognition of the effects of changes in the liability’s credit risk in other comprehensive income would create or enlarge an accounting mismatch in profit or loss. Changes in fair value attributable to a financial liability’s credit risk are not subsequently reclassified to profit or loss. Under IAS 39, the entire amount of the change in the fair value of the financial liability designated as fair value through profit or loss is presented in profit or loss.

• In relation to the impairment of financial assets, IFRS 9 requires an expected credit loss model, as opposed to an incurred credit loss model under IAS 39. The expected credit loss model requires an entity to account for expected credit losses and changes in those expected credit losses at each reporting date to reflect changes in credit risk since initial recognition. In other words, it is no longer necessary for a credit event to have occurred before credit losses are recognized.

• The new general hedge accounting requirements retain the three types of hedge accounting mechanisms currently available in IAS 39. Under IFRS 9, greater flexibility has been introduced to the types of transactions eligible for hedge accounting, specifically broadening the types of instruments that qualify for hedging instruments and the types of risk components of non-financial items that are eligible for hedge

F-29

accounting. In addition, the effectiveness test has been overhauled and replaced with the principle of an ‘economic relationship’. Retrospective assessment of hedge effectiveness is also no longer required. Enhanced disclosure requirements about an entity’s risk management activities have also been introduced.

The Entity is in the process of determining the potential impacts that will result in its consolidated financial statements for the adoption of this standard.

IFRS 15, Revenue from Contracts with Customers

In May 2014, IFRS 15 was issued which establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. IFRS 15 will supersede the current revenue recognition guidance including IAS 18 Revenue, IAS 11 Construction Contracts and the related Interpretations when it becomes effective.

The core principle of IFRS 15 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Specifically, the Standard introduces a 5-step approach to revenue recognition:

• Step 1: Identify the contract(s) with a customer.

• Step 2: Identify the performance obligations in the contract.

• Step 3: Determine the transaction price.

• Step 4: Allocate the transaction price to the performance obligations in the contract.

• Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

Under IFRS 15, an entity recognizes revenue when (or as) a performance obligation is satisfied, i.e. when ‘control’ of the goods or services underlying the particular performance obligation is transferred to the customer. Far more prescriptive guidance has been added in IFRS 15 to deal with specific scenarios. Furthermore, extensive disclosures are required by IFRS 15.

The Entity is in the process of determining the potential impacts that will result in its consolidated financial statements for the adoption of this standard.

IFRS 16 Leases

IFRS 16 (Leases) was issued in January 2016 and supersedes IAS 17 (Leases) and related interpretations. This new standard requires that most leases be presented in the statement of financial position for lessees under a single model, eliminating the distinction between operating and finance leases. Lessor accounting, however, remains largely unchanged and the distinction between operating and finance leases remains in effect. IFRS 16 is effective for periods beginning on or after January 1, 2019, with earlier adoption permitted if IFRS 15 has also been applied.

Under IFRS 16, a lessee recognizes a right-of-use asset and a lease liability. The right-of-use asset is treated similarly to other non-financial assets and depreciated accordingly and the liability accrues interest. This will typically produce a front-loaded expense profile (whereas operating leases under IAS 17 would typically have had straight-line expenses) as an assumed linear depreciation of the right-of-use asset and the decreasing interest on the liability will lead to an overall decrease of expense over the reporting period.

In addition, the financial liability is initially measured at the present value of the lease payments payable over the lease term, discounted at the rate implicit in the lease if the rate can be readily determined. If the rate cannot be readily determined, the lessee shall use their incremental borrowing rate.

However, a lessee may elect to account for lease payments as an expense on a straight-line basis over the lease term for leases with a lease term of 12 months or less and containing no purchase options (this election is made by class of underlying asset); and leases where the underlying asset has a low value when new, such as personal computers or small items of office furniture (this election can be made on a lease-by- lease basis).

F-30

IFRS 16 establishes different transitional provisions, including retrospective application or the modified retrospective application where the comparative period is not restated.

The Entity is in the process of assessing the potential impact that the adoption of this standard could have in its consolidated financial statements.

Amendments to IFRS 11 Accounting for Acquisitions of Interests in Joint Operations

The amendments to IFRS 11 provide guidance on how to account for the acquisition of a joint operation that constitutes a business as defined in IFRS 3 Business Combinations. Specifically, the amendments state that the relevant principles on accounting for business combinations in IFRS 3 and other standards (e.g. IAS 36 Impairment of Assets regarding impairment testing of a cash-generating unit to which goodwill on acquisition of a joint operation has been allocated) should be applied. The same requirements should be applied to the formation of a joint operation if and only if an existing business is contributed to the joint operation by one of the parties that participate in the joint operation.

The administration of the Entity does not anticipate that the application of these amendments to IFRS 11 will have a material impact on the Entity’s consolidated financial statements.

Amendments to IAS 1 Disclosure Initiative

The amendments to IAS 1 give some guidance on how to apply the concept of materiality in practice. The administration of the Entity does not anticipate that the application of these amendments to IAS 1 will have a material impact on the Entity’s consolidated financial statements.

Amendments to IAS 16 and IAS 38 Clarification of Acceptable Methods of Depreciation and Amortization

The amendments to IAS 16 prohibit entities from using a revenue-based depreciation method for items of property, plant and equipment. The amendments to IAS 38 introduce a rebuttable presumption that revenue is not an appropriate basis for amortization of an intangible asset. This presumption can only be rebutted in the following two limited circumstances:

• When the intangible asset is expressed as a measure of revenue; or

• When it can be demonstrated that revenue and consumption of the economic benefits of the intangible asset are highly correlated.

Currently, the Entity uses the straight-line method for depreciation and amortization of property, and furniture, office equipment and vehicles and intangible assets for airport concessions; for machinery, the Entity uses the method of hours of use. Amortization of intangible assets for highway concessions is determined based on vehicle flow.

The administration of the Entity believes that the methods used are the most appropriate to reflect the consumption of the economic benefits inherent in the respective assets and accordingly, does not anticipate that the application of these amendments will have a material impact on the Entity’s consolidated financial statements.

Amendments to IAS 12 Income Taxes

The amendments to IAS 12 (Income Taxes), clarify that unrealized losses in debt instruments measured at fair value and for tax purposes measured at cost, originate a temporal difference, regardless if the instrument holder expects to recover the book value of the instrument through its sale or its use. In addition, they specify that the book value in an asset does not limit the estimation of probable future taxable profits and that when comparing the deductible temporary differences with future taxable profits, the latter exclude tax deductions that would result from the reversal of the above mentioned deductible temporary differences. These amendments are effective for annual periods starting from January 1, 2017, with retrospective application, although early adoption is permitted.

F-31

The Entity is in the process of assessing the potential impact that the adoption of these amendments could have in its consolidated financial statements.

Amendments to IAS 7 (Cash Flow Statement) Disclosure Initiative

Amendments to IAS 7 (Cash Flow Statement) require separate disclosure of the following changes in liabilities that arise from financing activities:

(i) changes in cash flows from financing activities;

(ii) changes by acquisition or loss of control in subsidiaries or other businesses;

(iii) exchange rate fluctuations;

(iv) changes in fair values; and other changes.

A way of complying with the new requirement is through a reconciliation between the opening and final balance of liabilities in the statement of financial position that arise from financing activities. Liabilities arising from financing activities are those whose cash flows are classified, or that will be classified in the future, such as financing activities cash flows in the statement of cash flow. The new disclosure requirements also apply to changes in financial assets as long as comply with the same definition.

These amendments are effective for annual periods beginning on January 1, 2017, with early adoption permitted, and entities are not require to submit comparative information when applied for the first time.

The Entity is in the process of assessing the potential impact that the adoption of these amendments could have in its consolidated financial statements.

Annual Improvements to IFRSs 2012-2014 Cycle

The Annual Improvements to IFRSs 2012-2014 Cycle include a number of amendments to various IFRSs, which are summarised below.

The amendments to IFRS 5 introduce specific guidance in IFRS 5 for when an entity reclassifies an asset (or disposal group) from held for sale to held for distribution to owners (or vice versa). The amendments clarify that such a change should be considered as a continuation of the original plan of disposal and hence requirements set out in IFRS 5 regarding the change of sale plan do not apply. The amendments also clarify the guidance for when held-for-sale accounting is discontinued.

The amendments to IFRS 7 provide additional guidance to clarify whether a servicing contract is continuing involvement in a transferred asset for the purpose of the disclosures required in relation to transferred assets.

The amendments to IAS 19 clarify that the rate used to discount post-employment benefit obligations should be determined by reference to market yields at the end of the reporting period on high quality corporate bonds. The assessment of the depth of a market for high quality corporate bonds should be at the currency level (i.e. the same currency as the benefits are to be paid). For currencies for which there is no deep market in such high quality corporate bonds, the market yields at the end of the reporting period on government bonds denominated in that currency should be used instead.

The administration of the Entity does not anticipate that the application of these amendments to IFRS will have a material impact on the Entity’s consolidated financial statements.

F-32

b. Disclosure restatements

Certain disclosures in the financial statements for the year ended December 31, 2014 and 2013 have been restated as follows:

Accounts receivable

– The amounts disclosed in the average age (days) of accounts receivable from customers past due but not impaired of Note 7.b, at December 31 2014 and 2013 were modified; instead of disclosing the accounts receivable aged from customers past due but not impaired, the disclosure presents the average age (days) of all accounts receivable. Turnover of accounts receivable was determined based on total revenues less effects of fair value on initial recognition of inventories in 2014, as it is a non-recurring transaction, and less construction revenues from the Rio de los Remedios project, given that the collection of this receivable is expected over the long-term and inclusion of current revenues and a long-term receivable would distort the is is a a long-term projec; accounts receivable average of these transactions are excluded also. The average age (days) of accounts receivable from customers, both originally filed and as amended, is as follows:

c. Operations and transactions in foreign currency

Translation of financial statements of foreign subsidiaries

Upon consolidation, the assets and liabilities of operations in countries whose currency is other than the Mexican peso, are translated into Mexican pesos using the exchange rates prevailing at the end of each reporting period. Items of income and expenses are translated at average rates of exchange prevailing in each period, unless these fluctuate significantly during the period, in which case the exchange rates at the date the transactions are effected are used. The exchange rate differences arising, if applicable, are recognized in other comprehensive income and are accumulated in equity (attributed to non-controlling interests as appropriate).

When the functional currency of a foreign transaction differs from the recording currency, before applying the terms of the preceding paragraph, the recording currency must be converted to the

F-34

functional currency by using the following methodology: monetary assets and liabilities are converted by using the exchange rate in effect at the date of the statement of changes in financial position, while nonmonetary assets and liabilities, stockholders’ equity, income, costs and expenses must be considered at the historical exchange rate. Any differences arising from this method must be recognized in the results of the year.

On the disposal of a foreign operation, all of the accumulated exchange differences in respect of that operation attributable to the Entity are reclassified to profit or loss in the year of disposal or when control is lost.

In addition, in relation to a partial disposal of a subsidiary that includes a foreign operation that does not result in the Entity losing control over the subsidiary, the proportionate share of accumulated exchange differences are re-attributed to non-controlling interests and are not recognized in profit or loss. For all other partial disposals (i.e. partial disposals of associates or joint arrangements that do not result in the Entity losing significant influence or joint control), the proportionate share of the accumulated exchange differences is reclassified to results.

Goodwill and fair value adjustments to identifiable assets acquired and liabilities assumed through acquisition of a foreign operation are treated as assets and liabilities of the foreign operation and translated at the rate of exchange prevailing at the end of each reporting period. Exchange differences arising are recognized in other comprehensive (loss) income.

Foreign currency transactions

Foreign currency transactions are recorded at the exchange rate in effect at the date of the transaction date. Monetary assets and liabilities denominated in foreign currency are translated into Mexican pesos at the exchange rate prevailing at the end of the reporting period. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated. Exchange fluctuations are recorded in profit or loss, except for:

• Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the cost of those assets when they are regarded as an adjustment to interest costs on those foreign currency borrowings;

• Exchange differences on transactions entered into in order to hedge certain foreign currency risks (see paragraph (w) below for hedging accounting policies); and

• Exchange differences on monetary items such as receivables from or payables to a foreign operation for which settlement is neither planned nor likely to occur (therefore forming part of the net investment in the foreign operation), which are recognized initially in other comprehensive income and reclassified from equity to profit or loss on disposal or partial disposal of the net investment.

d. Cash and cash equivalents and restricted cash

Cash and cash equivalents consist mainly of bank deposits in checking accounts and short-term investments, highly liquid and easily convertible into cash, maturing within three months as of their acquisition date, which are subject to immaterial value change risks. Cash is stated at nominal value and cash equivalents are measured at fair value.

Cash and investments subject to restrictions or intended for a specific purpose are presented separately under current or non-current assets as the case may be.

e. Construction materials inventories

Construction materials inventories are stated at the lower of cost, using average cost, or net realizable value. Net realizable value represents the estimated selling price for inventories less all estimated costs of completion and costs necessary to make the sale.

F-35

Reductions to the value of inventories are comprised of estimates representing the impairment of inventories.

f. Real estate inventories

Housing and housing development costs comprise the cost of the acquisition of land, improvements, permits and licenses, labor costs, materials and direct and indirect costs. Borrowing costs incurred during the construction period are capitalized.

Land to be developed over a period of more than 12 months is classified under non-current assets and is recorded at acquisition cost.

The valuation of inventory, the control of the cost of sales and the related profit are recognized through a cost budgeting system. The cost budgeting system is reviewed quarterly and updated periodically when modifications are made to sales price or cost estimates of construction and development of the home. Variations in the original cost budget that require a change in cost of sales of inventory are applied to results in the period in which they are determined. Inventory costs include (i) the cost of land, (ii) rights, licenses, permits and other project costs, (iii) housing development costs, construction and infrastructure costs, (iv) borrowing costs incurred during the construction period and (v) administration and supervision of real estate. The costs related to real estate projects are capitalized during development of the project and are applied to cost of sales in the proportion in which revenues are recognized.

A review of income and estimates for the projects currently in progress, to assess the operating margin of the sector costs, is performed quarterly. Additionally, on an annual basis, the Entity performs formal impairment tests based on discounted cash flow projections and to determine the expected rates of returns of the project. Such cash flow projections incorporate actual revenues and costs through the date of the evaluation as well as estimated future investments the Entity expects to incur to complete and sell the project. Revenues are projected based on the current selling price of the home, considering any discounts that the Entity may offer. Selling prices for the moderate-income sector are based on market studies of what a willing buyer would pay, comparable prices for similar projects in the areas in which the Entity develops and the general economic conditions in Mexico. The Entity only offers discounts on sale prices of homes when sales prices have increased over time and the discount would not exceed the original sale price of the home. The policy is not to grant discounts when the discounted sales price would result in a value lower than the carrying value of the inventory. Management determines discounts on a home-by-home basis. Cost estimates are based on the cost budgeting system as discussed above. Impairment is recognized when the sales price less costs to sell is less than the carrying amount of the inventory. Accordingly, the Entity only recognizes impairment on inventories in the moderate-income sector if it offers discounts greater than the operating margin or otherwise significantly reduce the prices below the operating margin because of, for example, market forces or deteriorating economic factors.

The Entity assesses the impairment of real estate inventories at each balance sheet date and appraisals are conducted every two years or more frequently if events or changes in circumstances indicate that certain amounts accrued will not be recoverable. If the valuation is less than the carrying value of the inventory, an impairment is recorded in results of the period in which the impairment was determined.

If circumstances that previously caused the reduction no longer exist or when there is clear evidence of an increase in net realizable value due to a change in economic circumstances, the previously recognized impairment is reversed.

g. Property, machinery and equipment

Expenditures for property, machinery and equipment are capitalized and valued at acquisition cost.

F-36

Depreciation is recognized so as to write off the cost or deemed cost of assets (other than freehold land and properties under construction). Depreciation of buildings, furniture, office equipment and vehicles is calculated using the straight-line method over the useful life of the asset, taking into consideration the related asset’s residual value. Depreciation of machinery and equipment is calculated according to the hours of use method (machine hours used in regard to total estimated usage hours of the assets during their useful lives, which range from 4 to 10 years). Depreciation begins in the month in which the asset is placed in service. The useful lives of assets are as follows:

	Useful
	lives (years)
Buildings	20 to 50
Machinery and operating equipment	4 to 10
Furniture, office equipment and vehicles	4 to 10
Machinery and equipment leasing	3 to 5

Financing costs incurred during the construction and installation of buildings and machinery and equipment are capitalized.

Residual values, useful lives and depreciation methods are reviewed at the end of each year and adjusted prospectively if applicable. If the depreciation method is changed, this is recognized in retrospectively.

The depreciation of property, machinery and equipment is recorded in results. Land is not depreciated.

Disposal of assets

The gain or loss on the sale or retirement of an item of property, machinery and equipment is calculated as the difference between the net revenue from the sale and the carrying value of the asset, and is recognized in income when all risks and rewards of ownership of the asset is transferred to the buyer, which generally occurs when ownership of the asset is transferred to the buyer.

Replacements or renewals of complete items that extend the useful life of the asset, or its economic capacity are recognized as an increase to property, machinery and equipment, with the consequent withdrawal or derecognition of the replaced or renewed.

Construction in progress

Construction in progress is carried at cost less any recognized impairment loss. Cost includes professional fees and, in the case of qualifying assets, borrowing costs capitalized in accordance with the accounting policy of the Entity. Such properties are transferred to the appropriate categories of property, machinery and equipment when completed and ready for intended use. The depreciation of these assets, as well as other properties, begins when the assets are ready for use.

Subsequent costs

Subsequent costs form part of the value of the asset or are recognized as a separate asset only when it is probable that such disbursement represents an increase in productivity, capacity, efficiency or an extension of the life of the asset and the cost of the item can be determined reliably. All other expenses, including repairs and maintenance are recognized in comprehensive income as incurred.

Machinery and equipment leasing

Assets held under finance leases are depreciated over their estimated useful lives on the same basis as owned assets. However, when there is no reasonable certainty that ownership will be obtained by the end of the least term, assets are depreciated over the shorter of the lease term and their useful lives.

F-37

h. Investment property

Investment properties are properties held to earn rentals and/or for capital appreciation (including property under construction for such purposes). Investment properties are measured initially at cost, including transaction costs. Subsequent to initial recognition, investment properties are measured at fair value. Gains and losses arising from changes in the fair value of investment properties are included in profit or loss in the period in which they arise.

An investment property is derecognized upon disposal or when the investment property is permanently withdrawn from use and no future economic benefits are expected from the disposal. Any gain or loss arising on derecognition of the property (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in profit or loss in the period in which the property is derecognized.

i. Leasing

Leases are classified as finance leases whenever the terms of the contract lease transfer substantially all the risks and rewards of ownership to the lessee. All other leases are classified as operating leases.

Financial leasing

In financial leasing where the Entity is the lessee, assets are initially recognized as assets of the Entity at their fair value at the inception of the lease or, if lower, at the present value of the minimum lease payments. The liability to the lessor is included in the statement of financial position as other accounts payable.

Lease payments are apportioned between finance expenses and reduction of the lease obligation so as to achieve a constant rate of interest on the remaining balance of the liability. Finance expenses are recognized immediately in profit or loss, unless they are directly attributable to qualifying assets, in which case they are capitalized in accordance with the Entity ’s general policy for borrowing costs (see paragraph j).

Assets held under finance leases are depreciated over their estimated useful lives on the same basis as owned assets; however, if there is no reasonable certaintly that the Entity will obtain title to the assets at the end of the lease term, the assets are depreciated over the shorter of the lease term or the useful life of the asset.

Operating leasing

As lessor

Rental income from operating leases is recognized on a straight-line basis over the term of the relevant lease. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized in profit using the same criteria used for the recognition of lease income.

As lessee

Any payment or collection made upon execution of an operating lease is treated as an advanced payment or collection that is recognized in results over the lease term, as the benefits of the leased asset are received or transferred.

The costs and expenses arising under operating leases are recognized in results using the straight line method during the term of the lease. Contingent rentals arising under operating leases are recognized as an expense in the period in which they are incurred.

j. Borrowing costs

Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale.

F-38

Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. All other borrowing costs are recognized in profit or loss in the period in which they are incurred.

k. Business combination

Acquisitions of businesses are accounted for using the acquisition method. The consideration transferred in a business combination is measured at fair value at the acquisition date, as well as the net assets and liabilities acquired. Acquisition-related costs are generally recognized in profit or loss as incurred.

Identifiable assets acquired and liabilities assumed of the acquiree that meet the conditions for recognition under IFRS 3, Business Combinations are recognized at their fair value at the acquisition date, except that:

• Deferred tax assets or liabilities, and assets or liabilities related to employee benefit arrangements are recognized and measured in accordance with IAS 12 and IAS 19 respectively;

• Liabilities or equity instruments related to share-based payment arrangements of the acquiree or share-based payment arrangements of the Entity entered into to replace share-based payment arrangements of the acquire are measured in accordance with IFRS 2, Share-based Payments (“IFRS 2”) at the acquisition date; and

• Assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5 are measured in accordance with that standard.

Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non-controlling interest in the acquiree, and the fair value of previous shareholding of the acquirer in the acquiree (if any) over the net amounts of identifiable assets acquired and liabilities assumed at the acquisition date. If after a revaluation net of the amounts of identifiable assets acquired and liabilities assumed at the date of acquisition exceeds the sum of the consideration transferred, the amount of any non-controlling interest in the acquiree and the fair value of previous shareholding the acquirer in the acquiree (if any), the excess is recognized immediately in the income statement as a gain on bargain purchase.

Non-controlling interests that are shareholdings and entitle their holders a proportionate share of the net assets of the acquired Entity in the event of liquidation can be initially measured either at fair value or the value of the proportionate share of non-controlling interest in the amounts recognized of the identifiable net assets of the acquired Entity. The measurement option is applicable on each transaction. Other types of non-controlling interests are measured at fair value or, when applicable, based on the specification by others IFRS.

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Entity reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized at that date.

“Measurement period” is from the date of purchase until the Entity has obtained full information about facts and circumstances that existed at the date of acquisition, and can not exceed one year from the acquisition date.

When the consideration transferred in a business combination includes assets or liabilities resulting from a contingent consideration arrangement, the contingent consideration is measured at its

F-39

acquisition-date fair value and included as part of the consideration transferred in a business combination. Subsequent changes in fair value are adjusted against the cost of acquisition when they are classified as measurement period adjustments. The accounting treatment for changes in fair value of contingent consideration that does not qualify as measurement period adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not remeasured at subsequent reporting dates and its subsequent settlement is accounted for within equity. Contingent consideration that is classified as an asset or liability is remeasured at subsequent reporting dates in accordance with IAS 39, or IAS 37 Provisions, Contingent Liabilities and Contingent Assets (“IAS 37”), as appropriate, recognizing the corresponding gain or loss in the statement of results and other comprehensive income (loss).

Goodwill is not amortized and is subject to impairment tests annually or earlier if indicators of impairment are presented. For assessing impairment, goodwill is allocated to each cash-generating unit of which the Entity expects to make profits. If the recoverable amount of the cash-generating unit is less than the carrying amount of the unit, the impairment loss is allocated first to reduce the carrying amount of goodwill allocated to the unit and then to the other assets of unit, proportionally, based on the carrying amount of each asset in the unit. The impairment loss recognized for goodwill purposes cannot be reversed at a later period.

Upon the disposal of a subsidiary, the amount attributable to goodwill is included in determining the gain or loss on disposal.

The Entity’s policy for goodwill arising from the acquisition of an associate is described in subsection (l) below.

When a business combination is achieved in stages, the previously held equity interest in the acquiree is remeasured to fair value at the acquisition date (i.e. the date when the Entity obtains control) and the resulting gain or loss, if any, is recognized in results. Amounts arising from interests in the acquiree prior to the acquisition date that have previously been recognized in other comprehensive income are reclassified to profit or loss where such treatment would be appropriate if that interest were disposed of.

l. Investments in associates and joint ventures

An associate is an entity over which the Entity has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies.

A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control.

The results of associated companies and joint venture are incorporated in the consolidated financial statements using the equity method, unless the investment is classified as held for sale, in which case it is accounted for in accordance with IFRS 5.

Under the equity method, an investment in an associate or joint venture is initially recognized in the consolidated statement of financial position at cost and adjusted thereafter to recognize the Entity’s share of the profit or loss and other comprehensive income of the associate or joint venture. When the Entity’s share of losses of an associate exceeds the Entity’s interest in that associate (which includes any long-term interests that, in substance, form part of the Entity’s net investment in the associate), the Entity discontinues recognizing its share of further losses. Additional losses are recognized only to the extent that the Entity has incurred legal or constructive obligations or made payments on behalf of the associate or joint venture.

F-40

Any excess of the cost of acquisition over the Entity’s share of the net fair value of the identifiable assets, liabilities and contingent liabilities of an associate or joint venture recognized at the date of acquisition is recognized as goodwill, which is included within the carrying amount of the investment. Any excess of the Entity’s share of the net fair value of the identifiable assets, liabilities and contingent liabilities over the cost of acquisition, after reassessment, is recognized immediately in profit or loss.

The requirements of IAS 39 are applied to determine whether it is necessary to recognize any impairment loss with respect to the Entity’s investment in an associate or joint venture. When necessary, the entire carrying amount of the investment (including goodwill) is tested for impairment in accordance with IAS 36 Impairment of Assets (“IAS 36”) as a single asset by comparing its recoverable amount (higher of value in use and fair value less costs to sell) with its carrying amount. Any impairment loss recognized forms part of the carrying amount of the investment. Any reversal of that impairment loss is recognized in accordance with IAS 36 to the extent that the recoverable amount of the investment subsequently increases.

Upon disposal of an associate or joint venture that results in the Entity losing significant influence over that associate or joint venture, any retained investment is measured at fair value at that date and the fair value is regarded as its fair value on initial recognition as a financial asset in accordance with IAS 39. The difference between the previous carrying amount of the associate or joint venture attributable to the retained interest and its fair value is included in the determination of the gain or loss on disposal of the associate or joint venture. In addition, the Entity accounts for all amounts previously recognized in other comprehensive income in relation to that associate on the same basis as would be required if that associate had directly disposed of the related assets or liabilities. Therefore, if a gain or loss previously recognized in other comprehensive income by that associate or joint venture would be reclassified to profit or loss on the disposal of the related assets or liabilities, the Entity reclassifies the gain or loss from equity to profit or loss (as a reclassification adjustment) when it loses significant influence over that associate or joint venture.

When a group entity transacts with its associate or joint venture, profits and losses resulting from the transactions with the associate or joint venture are recognized in the Entity’ consolidated financial statements only to the extent of interests in the associate or joint venture that are not related to the Entity.

m. Interest in joint operations

A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the assets, and obligations for the liabilities, relating to the arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control.

When a subsidiary of the Entity operates in the context of joint operations, the Entity as a joint operator recognizes in relation to its interest in a joint operation:

• Its assets, including its share of any assets held jointly.

• Its liabilities, including its share of any liabilities incurred jointly.

• Its revenue from the sale of its share of the output arising from the joint operation.

• Its share of the revenue from the sale of the output by the joint operation.

• Its expenses, including its share of any expenses incurred jointly.

When a subsidiary of the Entity enters into transactions with a joint arrangement in which it is a joint operator (such as a sale or contribution of assets), the Entity is considered to be conducting the transaction with the other parties to the joint operation, and gains and losses resulting from the transactions are recognized in the Entity’s consolidated financial statements only to the extent of other parties’ interests in the joint operation.

When a subsidiary of the Entity enters into transactions with a joint operation in which an entity of the Entity is a joint operator (such as a purchase of assets), the Entity does not recognize its share of the gains and losses until it resells those assets to a third party.

F-41

n. Investment in concessions

Under all of the Entity’s concession arrangements, (i) the grantor controls or regulates what services the Entity must provide with the infrastructure, to whom it must provide them, and at what price; and (ii) the grantor controls, through ownership, any significant residual interest in the infrastructure at the end of the term of the arrangement. Accordingly, the Entity classifies the assets derived from the construction, administration and operation of the service concession arrangements either as intangible assets, financial assets (accounts receivable) or a combination of both.

A financial asset results when an operator constructs or makes improvements to the infrastructure, in which the operator has an unconditional right to receive a specific amount of cash or other financial assets during the contract term. An intangible asset results when the operator constructs or makes improvements and is allowed to operate the infrastructure for a fixed period after construction is complete, in which the future cash flows of the operator have not been specified, because they may vary depending on the use of the asset, and are therefore considered contingent. Both a financial asset and an intangible asset may result when the return/gain for the operator is provided partially by a financial asset and partially by an intangible asset.

Financial assets are recorded at fair value and are valued at amortized cost by calculating interest by the effective interest method at the date of the financial statements, based on the yields determined for each of the concession contracts. Interest income on financial assets from concessions are recognized within revenues, as they form part of ordinary operations of the Entity and as such, form part of the general objective of the concession activity, carried out regularly and thereby providing revenues on a routine basis.

The cost of financing incurred during the construction period is capitalized.

Investments in concessions resulting in the recognition of an intangible asset are recorded at acquisition value or construction cost and are amortized, in the case of investment in highways, tunnels and concessions that involve the use of facilities for the duration of the concessions, based on units of production. For water treatment plants, amortization is based on treated water volumes. In the airport concessions, amortization is based on the term thereof which is 50 years.

Major maintenance provisions

The Entity measures and recognizes its contractual obligations related to major maintenance of infrastructure as it accrues, in conformity with IAS 37. When the effect of the time value of money is material, the amount of the provision equals the present value of the expenditures expected to be required to settle the obligation. Where discounting is used, the carrying amount of the provision increases each period to reflect the passage of time and this increase is recognized as a borrowing cost. After initial recognition, provisions are reviewed at the end of each reporting period and adjusted to reflect current best estimates. Adjustments to provisions arise from three sources: (i) revisions to estimated cash flows (both in amount and timing); (ii) changes to present value due to the passage of time; and (iii) revisions of discount rates to reflect prevailing current market conditions. In periods following the initial recognition and measurement of the maintenance provision at its present value, the provision is revised to reflect estimated cash flows being closer to the measurement date. The unwinding of the discount relating to the passage of time is recognized as a financing cost and the revision of estimates of the amount and timing of cash flows is a reassessment of the provision and charged or credited as an operating item within the consolidated statements of results and other comprehensive income (loss).

The Entity establishes periodic maintenance plans to the infrastructure for airports. The estimated major maintenance costs are based on the master develop plan (MDP), which is reviewed and updated every five years. These plans are sufficient to maintain the concession within the conditions specified by the grantor and to ensure delivery of the assets in good condition at end of the term of the concession.

F-42

o. Government grants

Agencies of the Mexican government have provided grants to the Entity to finance certain concession investments. The conditions set forth with respect to the grants are approved by the competent agencies.

The Entity identifies government grants with assets for which the grant implies the purchase of the asset or the construction or acquisition of other assets, restricting the type or location of such assets or the periods during which they are to be acquired or held to match the terms and conditions of the grant.

Government grants that are receivable as compensation for expenses or losses already incurred or for the purpose of giving immediate financial support to the Entity with no future related costs are recognized in profit or loss in the period in which they become receivable.

Grants for the acquisition of assets are presented net against the related asset, and are applied to results over the same period and using the same amortization criteria as that of the related asset, except when they are recognized at the time of their collection, because no basis existed for allocating a grant to periods other than that in which it was received.

Government grants are not recognized until there is reasonable assurance that the Entity will comply with the conditions attached to them and that the grants will be received. Receipt of a grant does not provide conclusive evidence that the conditions attached to it have been or will be fulfilled.

p. Prepaid expenses

Prepaid assets mainly consist of costs related to uncompleted construction contracts, (mainly related to insurance and performance bonds) which are recorded at historical cost and amortized over the estimated useful life of the asset, as applicable.

q. Applications of IT

Costs associated with software maintenance are recognized as expenses when incurred. The acquisition and development costs that are directly attributable to the design, implementation and testing of identifiable and unique software that the Entity manages, are recognized as other assets when they fulfill the following criteria:

– It is technically possible to complete the software so that it can be used;

– Management intends to complete the software and use or sell it;

– The ability to use or sell the software exists;

– It can be shown that it is probable that the computer program will generate future economic benefits;

– Existence of the technical, financial and other resources to complete the development of software that allows use or sale, and the expenditure attributable to the software during its development can be measured reliably.

The direct costs are capitalized as part of cost of computer programs and include the costs of employees performing the computer program and a portion of the indirect costs.

Development costs of computer programs that are recognized as assets are amortized on a straight line from the start of operations of each application within their estimated useful lives fluctuating between three to five years.

r. Impairment of long-lived assets in use

Management periodically evaluates the impairment of long-lived assets in order to determine whether there is evidence that those assets have suffered an impairment loss. If impairment indicators exist, the recoverable amount of assets is determined, with the help of independent experts, to determine the extent of the impairment loss, if any. When it is not possible to estimate the recoverable amount of an

F-43

individual asset, the Entity estimates recoverable amount of the cash-generating unit to which the asset belongs. Where a reasonable and consistent basis of allocation can be identified, corporate assets are also allocated to individual cash-generating units, or otherwise they are allocated to the smallest group of cash-generating units for which a reasonable and consistent allocation basis can be identified.

Intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment at least annually, and whenever there is an indication that the asset may be impaired.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognized immediately in profit or loss.

Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognized immediately in profit or loss.

The Federal Government granted the airport concessions as a package of thirteen airports. The concessionaires are required to operate the airports, independently of the results that generate individually; therefore, each airport individually can not be considered as a cash generating unit; the assessment of impairment is determined by considering the figures of the entire airports segment.

s. Assets classified as held for sale

Non-current assets and disposal groups are classified as held for sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use. This condition is regarded as met only when:

i) the asset (or disposal group) is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such asset (or disposal group),

ii) its sale is highly probable,

iii) Management must be committed to the sale, and

iv) the sale is expected to be completed within one year from the date of classification.

In addition, IFRS requires separate presentation of the results of the discontinued operation in the consolidated income statement, retrospectively for all comparative periods. Discontinued operations consider only those assets available for sale representing a line of business or geographical area.

When the Entity is committed to a sale plan involving loss of control of a subsidiary, all of the assets and liabilities of that subsidiary are classified as held for sale when the criteria described above are met, regardless of whether the Entity will retain a non-controlling interest in its former subsidiary after the sale.

When the Entity is committed to a sale plan involving disposal of an investment, or a portion of an investment, in an associate or joint venture, the investment or the portion of the investment that will be disposed of is classified as held for sale when the criteria described above are met, and the Entity discontinues the use of the equity method in relation to the portion that is classified a held for sale. Any retained portion of an investment in an associate or a joint venture that has not been classified as held for sale continues to be accounted for using the equity method. The Entity discontinues the use of the equity method at the time of disposal when the disposal results in the Entity losing significant influence over the associate or joint venture.

F-44

After the disposal takes place, the Entity accounts for any retained interest in the associate or joint venture in accordance with IAS 39 unless the retained interest continues to be an associate or a joint venture, in which case the Entity uses the equity method (see the accounting policy regarding investments in associates or joint ventures described in paragraph l).

Non-current assets (and disposal groups) classified as held for sale are measured at the lower of their previous carrying amount and fair value less costs to sell.

The circumstances of each asset available for sale are analyzed when the sale is not made within a year to ensure it remains appropriate to classify it as available for sale.

t. Investment units

Certain financial instruments are lined to inflation, such as those denominated in investment units (UDIs). UDIs are units of value established by the Bank of Mexico to address mortgage loan obligations or any financial or commercial transaction and are similar to a floating rate financial instrument. The value of the UDI increases daily to maintain the purchasing power of money and is published in the Official Gazette in Mexico. The value of UDIs is determined considering the Mexican National Consumer Price Index (“INPC”), taking into account inflation. The UDI-denominated financial instruments are valued at amortized cost. In determining the effective interest rate to measure debt instruments using the effective interest method, expected future changes in the value of the UDI are not taken into account. Changes in the value of the UDI during the year are recognized in the statement of income and comprehensive income.

As of December 31, 2015, 2014 and 2013 the UDI value was Ps.5.3811, Ps.5.2704 and Ps.5.0587, respectively.

u. Financial instruments

Financial assets and financial liabilities are recognized when the Entity becomes a party to the contractual provisions of the instruments.

Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities (other than financial assets and financial liabilities at fair value through profit or loss) are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at fair value through profit or loss are recognized immediately in profit or loss.

Financial assets are classified into four categories, which in turn determine the form of recognition and valuation of financial assets: “Financial assets at fair value through profit or loss”, “investments held-to-maturity”, “financial assets available-for-sale” and “loans and receivables”. The classification depends on the nature and purpose of the financial assets and is determined by the administration of the Entity upon initial recognition. The Entity generally only has financial assets at fair value through profit or loss and loans and receivables.

In the consolidated statement of financial position, financial assets are classified into current and noncurrent, depending on whether their maturity is less than / equal to or greater than 12 months.

Financial assets at fair value through profit or loss

Financial assets are classified at fair value through profit or loss when the financial asset is held for trading or it is designated fair value through results. A financial asset is classified as held for trading if:

• It has been acquired principally for the purpose of selling it in the near term; or

F-45

• On initial recognition it is part of a portfolio of identified financial instruments that the Entity manages together and has a recent actual pattern of short-term profit-taking; or

• It is a derivative (except those designated as hedging instruments or that is a financial guarantee).

Financial assets at fair value through profit of loss are recorded at fair value, recognizing in results any gain or loss arising from their remeasurement. The gain or loss recognized in results includes any dividend or interest earned from the financial asset and is recorded in interest expense or income in the consolidated statements income and other comprehensive income. Fair value is determined as described in Note 30.f.

Loans and receivables

Loans and receivables are non-derivative financial assets, that have fixed or determinable payments that are not quoted in an active market. After initial recognition, loans and receivables are measured at amortized cost using the effective interest method.

“Amortized cost” means the initial amount recognized for a financial asset or liability less principal repayments, less (or plus) the cumulative amortization using the effective interest method of any difference between the initial amount and the amount at maturity, less any reduction (directly or through a reserve) for impairment or bad debt.

Impairment of financial assets

Financial assets other than financial assets at fair value through profit or loss are assessed for indicators of impairment at the end of each reporting period. Financial assets are considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of the investment have been affected.

Objective evidence of impairment could include:

• Significant financial difficulty of the issuer or counterparty; or

• Breach of contract, such as a default or delinquency in interest or principal payments; or

• It becoming probable that the borrower will enter into bankruptcy or financial reorganization; or

• The disappearance of an active market for that financial asset because of financial difficulties.

The carrying amount of the financial asset is reduced directly by the impairment loss, except for trade receivables, where the carrying amount is reduced through the use of an allowance account. When a trade receivable is considered uncollectible, it is written off against the allowance account. Subsequent recoveries of amounts previously written off are recorded in results. Changes in the carrying amount of the allowance account are recognized in profit or loss.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss is reversed through results to the extent that the carrying amount of the investment at the date the impairment is reversed does not exceed the amortized cost if the impairment would not have been recognized.

Derecognition of financial assets

On derecognition of a financial asset in its entirety, the difference between the asset´s carrying amount and the sum of the consideration received and receivable and the cumulative gain or loss that had been recognized in other comprehensive income and accumulated in equity is recognized in results.

F-46

Financial liabilities

Financial liabilities are classified as financial liabilities at fair value through profit or loss, or other financial liabilities based on the substance of contractual arrangements.

Financial liabilities at fair value through profit or loss

A financial liability at fair value through profit or loss is a financial liability that is classified as held for trading or designated at fair value through profit or loss.

A financial liability is classified as held for trading if:

• It has been acquired principally for the purpose of repurchasing it in the near term; or

• On initial recognition it is part of a portfolio of identified financial instruments that are managed together for which there is evidence of a recent pattern of making short-term profits, or

• It is a derivative that accounting purposes does not comply with requirements to be designated as a hedging instrument.

A financial liability other than a financial liability held for trading may be designated as at fair value through profit or loss upon initial recognition if:

• Such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise; or

• The financial liability forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair value basis, in accordance with the Entity’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or

• It forms part of a contract containing one or more embedded derivatives, and IAS 39 permits the entire combined contract (asset or liability) to be designated as at fair value through profit or loss.

Financial liabilities at fair value through profit or loss are stated at fair value, with any gains or losses arising on remeasurement recognized in profit or loss. The net gain or loss recognized in results incorporates any interest paid on the financial liability and is included in effects of valuation of financial instruments in the statement income and other comprehensive income.

Other financial liabilities

Other financial liabilities, including loans, bond issuances and debt with lenders and trade creditors and other payables are valued initially at fair value, represented generally by the consideration transferred, net of transaction costs, and are subsequently measured at amortized cost using the effective interest method.

Derecognition of financial liabilities

The Entity derecognizes financial liabilities when, and only when, the obligations are discharged, cancelled or they expire. The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable is recognized in results.

F-47

Effective interest method

The effective interest method is a method of calculating the amortized cost of a financial asset or liability and of allocating interest income or cost over the relevant period. The effective interest rate is the rate that exactly discounts future cash receivable or payable (including all fees and points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the financial instrument, or (where appropriate) a shorter period, to the carrying amount of the financial asset or liability on its initial recognition. When calculating the effective interest rate, all cash flows must be estimated (for example, prepayment, call options “call” and the like) except for future credit losses. The calculation must include all commissions and payments or receipts between the parties to the financial instrument, including other premiums or discounts.

Offsetting of financial assets and liabilities

Offsetting of financial assets and liabilities in the consolidated statement of financial position only occurs for accounts receivable and payable arising in transactions that contractually, or by law, have established a right of setoff and for which the Entity has the intention to pay a net amount or to realize the asset and pay the liability simultaneously.

v. Risk management policy

The Entity is exposed to risks that are managed through the implementation of systems related to identification, measurement, limitation of concentration, mitigation and supervision of such risks. The basic principles defined by Entity in the establishment of its risk management policy are the following:

• Compliance with Corporate Governance Standards

• Establishment, by each different business line and subsidiary, of risk management controls necessary to ensure that market transactions are conducted in accordance with the policies, rules and procedures of the Entity

• Special attention to financial risk management, basically composed by interest rate, exchange rate, liquidity and credit risks (see Note 30).

Risk management in ICA is mainly preventive and oriented to the medium- and long-term, taking into consideration the most probable scenarios of evolution of the variables affecting each risk.

w. Derivative financial instruments

The Entity underwrites a variety of financial instruments to manage its exposure to the risks of volatility in interest rates and exchange rates, including foreign currency forward contracts, interest rate swaps and combined interest rate and foreign exchange swaps (cross currency swaps) related to the financing of its concession projects and construction. Note 26 includes a more detailed explanation of derivative financial instruments.

Derivatives are initially recognized at fair value at the date the derivative contract is entered into and are subsequently remeasured at fair value at the end of each reporting period. Fair value is determined based on recognized market prices. When the derivative is not listed on a market, fair value is based on valuation techniques accepted in the financial sector. Valuations are conducted quarterly in order to review the changes and impacts on the consolidated results.

The resulting gain or loss from remeasurement to fair value is recognized in profit or loss unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship.

A derivative with a positive fair value is recognized as a financial asset; a derivative with a negative fair value is recognized as a financial liability. A derivative is presented as a non-current asset or a non-current liability if the remaining maturity of the instrument is greater than 12 months and it is not expected to be realized or settled within 12 months. Other derivatives are presented as current assets or current liabilities.

F-48

Hedge accounting

At the inception of the hedge relationship, the Entity documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Entity documents whether the hedging instrument is highly effective in offsetting changes in fair values or cash flows of the hedged item.

When the related transaction fulfills all hedge accounting requirements, the derivative is designated as a hedging instrument when the contract is entered (either as a hedge of cash flow or hedge of foreign currencies or a fair value hedge). The decision to apply hedge accounting depends on economic or market conditions and economic expectations in the national or international markets. When the Entity contracts a derivative financial instrument for hedging purposes from an economic perspective but that instrument does not comply with all requirements established by IFRS to be considered as hedging instruments, gains or losses from such derivative financial instrument is applied to the results in the period in which it occurs.

The Entity’s policy not to enter into derivative financial instruments for speculative purposes, but certain instruments entered into by the Entity that do not qualify as hedging instruments and accounted for as trading instruments and the fluctuation in fair value is recognized in the financial results of the period in which they are measured.

Effectiveness tests of derivatives that qualify as hedging instruments from an accounting perspective are performed at least once every quarter and every month, if there is a significant change.

Note 26 include details of the fair values of derivative instruments used for hedging purposes.

Fair value hedges

The change in the fair value of the hedging instruments and the change in the hedged item attributable to the hedged risk are recognized in the line item in the statement of income and other comprehensive (loss) income relating to the hedged item.

Cash flow hedges

For cash flow hedges (including interest rate swaps and interest rate options) and hedging exchange rate designated as cash flow hedges and foreign currency instruments including foreign exchange, currency swaps foreign and foreign currency options, the effective portion of changes in fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income. The ineffective portion is recognized immediately in the financial results of the period.

Amounts previously recognized in other comprehensive income and accumulated in equity are reclassified to results in the periods when the hedged item is recognized in results, in the same line item in the statement of income and other comprehensive income where the hedged item is recognized. However, when a forecasted transaction that is hedged gives rise to the recognition of a non-financial asset or a non-financial liability, the gains and losses previously accumulated in equity are transferred from equity and are included in the initial measurement of the cost of the non-financial asset or non-financial liability.

F-49

Interruption of hedge accounting

Hedge accounting is discontinued when the Entity revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or when it no longer qualifies for hedge accounting. Any accumulated gain or loss on the hedging instrument recognized in other comprehensive income remains there until the hedged item affects results. When a forecasted transaction is no longer expected to occur, the accumulated gain or loss is reclassified immediately to results.

Embedded derivatives

Hedge accounting is discontinued when the Entity revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or when it no longer qualifies for hedge accounting. Any accumulated gain or loss on the hedging instrument recognized in other comprehensive income remains there until the hedged item affects results. When a forecasted transaction is no longer expected to occur, the accumulated gain or loss is reclassified immediately to results.

The Entity has no significant effects arising from embedded derivatives at the end of the periods reported.

Hedges of net investments in foreign operations

Hedges of net investments in foreign operations are accounted for similarly to cash flow hedges. Any gain or loss on the hedging instrument relating to the effective portion of the hedge is recognized in other comprehensive income and accumulated under the heading of foreign currency translation reserve. The gain or loss relating to the ineffective portion is recognized immediately in profit or loss, and is included in interest expense or income.

Gains and losses on the hedging instrument relating to the effective portion of the hedge accumulated in the foreign currency translation reserve are reclassified to profit or loss on the disposal of the foreign operation.

x. Provisions

Provisions are recognized when the Entity has a present obligation (legal or constructive) as a result of a past event, when it is probable that the Entity will be required to settle the obligation, and when a reliable estimate can be made of the amount of the obligation.

The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties associated with the obligation. When a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows.

The main provisions recognized by the Entity are for major maintenance (for concession assets), completion of construction and machinery leasing and related guarantees, and are classified as current or noncurrent based on the estimated time period to settle the obligation.

When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, a receivable is recognized as an asset if it is virtually certain that reimbursement will be received and the amount of the receivable can be measured reliably.

Restructurings

A restructuring provision is recognized when the Entity has developed a formal plan for the restructuring, and has created a valid expectation among those affected, that it will carry out the restructuring, either through commencement of the implementation of the plan or having announced its main features to those affected by the plan. The restructuring provision includes only the direct expenditures arising from it, which necessarily include amounts arising from the restructuring, and are not associated with the continuing operations of the Entity.

F-50

Contingent liabilities acquired in a business combination

Contingent liabilities acquired in a business combination are initially measured at fair value at the acquisition date. At the end of subsequent reporting periods, such contingent liabilities are measured at the higher of the amount that would be recognized in accordance with IAS 37 and the amount initially recognized less cumulative amortization recognized in accordance with IAS 18 Revenue.

y. Reserve for repurchase of shares

The Entity records a reserve for the repurchase of shares from amounts appropriated from retained earnings, to strengthen the supply and demand of its shares in the stock market, as permitted by Mexican Securities Law. The shareholders authorize the maximum disbursement for the repurchase of shares.

Purchases and sales of treasury shares are recorded decreasing or increasing stockholders’ equity of the Entity through the reserve for the repurchase of shares account, based on the cost of reacquisition and replacement of such shares, respectively. Any gain or loss is recorded as additional paid-in capital. Gains or losses arising from the purchase, sale, issue or cancellation of equity instruments of ICA are not recognized in results.

z. Income taxes

Income tax expense represents the sum of the tax currently payable and deferred tax. The tax currently payable is based on taxable profit for the year. Taxable profit differs from profit as reported in the consolidated statement of income and other comprehensive income because of items of income or expense that are taxable or deductible in periods different from when they are recognized in accounting profit or for items which are never taxable or deductible. Through December 31, 2013, the Business Flat Tax (“IETU”) was in effect, which was determined based on cash flows, considering the income received less the expenditures authorized by law. The income tax incurred was the higher of regular income tax (“ISR”) and IETU.

In December 2013, Congress approved the proposal of the Federal Government to amend certain aspects of the Law on Income Tax, among others, eliminate tax consolidation regime in which ICA was authorized by the Ministry of Finance and Public Credit to prepare its income tax on a consolidated basis, which included the proportional tax of taxable income or loss of its Mexican subsidiaries. The government established three alternatives are offered to companies to deconsolidate from a tax perspective and thus determine the deferred tax at December 31, 2013, including a deferred payment scheme over the next five fiscal years for the impact of deconsolidation.

The tax provisions of foreign subsidiaries are determined based on taxable income of each individual company.

Deferred income taxes are recognized for the applicable temporary differences resulting from comparing the accounting and tax values of assets and liabilities plus any future benefits from tax loss carryforwards. Except as mentioned in the following paragraph, deferred tax liabilities are recognized for all taxable temporary differences and deferred tax assets are recognized for all deductible temporary differences and the expected benefit of tax losses. The carrying amount of deferred tax assets is reviewed at the end of each reporting period and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered.

Deferred tax liabilities are recognized for taxable temporary differences associated with investments in subsidiaries, except where the Entity is able to control the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax assets arising from deductible temporary differences associated with such investments and interests are only recognized to the extent that it is probable that there will be sufficient taxable profits against which to utilize the benefits of the temporary differences and they are expected to reverse in the foreseeable future.

F-51

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Entity expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

Current and deferred taxes are recognized as income or expense in profit or loss, except when it relates to items recognized outside of profit or loss, as in the case of other comprehensive income, stockholders’ equity items, or when the tax arises from the initial recognition of a business combination, in which case the tax is recognized in other comprehensive income as part of the equity item in question or, in the recognition of the business combination, respectively.

In addition, deferred tax liabilities are not recognized if the temporary difference arises from the initial recognition of goodwill.

For the purposes of measuring deferred tax liabilities and deferred tax assets for investment properties that are measured using the fair value model, the carrying amounts of such properties are presumed to be recovered entirely through sale, unless the presumption is rebutted. The presumption is rebutted when the investment property is depreciable and is held within a business model whose objective is to consume substantially all of the economic benefits embodied in the investment property over time, rather than through sale. The management of the Entity reviewed the Entity’s investment property portfolios and concluded that none of the Entity’s investment properties are held under a business model whose objective is to consume substantially all of the economic benefits embodied in the investment properties over time, rather than through sale. Therefore, the Entity has determined that the “sale” presumption set out in the amendments to lAS 12 is not rebutted.

Assets and deferred tax liabilities are offset when a legal right to offset assets with liabilities exists and when they relate to income taxes relating to the same tax authorities and the Entity intends to liquidate its assets and liabilities on a net basis.

aa. Employee benefits

Retirement benefit costs and termination benefits

Payments to defined contribution retirement benefit plans are recognized as an expense when employees have rendered service entitling them to the contributions.

For defined benefit retirement benefit plans, the cost of providing benefits is determined using the projected unit credit method, with actuarial valuations being carried out at the end of each annual reporting period. Remeasurement, comprising actuarial gains and losses, the effect of the changes to the asset ceiling (if applicable) and the return on plan assets (excluding interest), is reflected immediately in the statement of financial position with a charge or credit recognized in other comprehensive income in the period in which they occur. Remeasurement recognized in other comprehensive income is reflected immediately in retained earnings and will not be reclassified to profit or loss. Past service cost is recognized in profit or loss in the period of a plan amendment. Net interest is calculated by applying the discount rate at the beginning of the period to the net defined benefit liability or asset. Defined benefit costs are categorized as follows:

• Service cost (including current service cost, past service cost, as well as gains and losses on curtailments and settlements).

• Net interest expense or income.

• Remeasurement.

The Entity presents the first two components of defined benefit costs in profit or loss in the line item costs and general expenses. Curtailment gains and losses are accounted for as past service costs.

F-52

The retirement benefit obligation recognized in the consolidated statement of financial position represents the actual deficit or surplus in the Entity’s defined benefit plans. Any surplus resulting from this calculation is limited to the present value of any economic benefits available in the form of refunds from the plans or reductions in future contributions to the plans.

A liability for a termination benefit is recognized at the earlier of when the entity can no longer withdraw the offer of the termination benefit and when the entity recognizes any related restructuring costs.

Short-term employee benefits

Liabilities recognized in connection with employee benefits in the short term are valued at the undiscounted amount of benefits expected to be paid in exchange for related services.

Certain subsidiaries are subject to statutory employee profit sharing (“PTU”) payment stemming from legal dispositions, which is recorded in the results of the year in which it is incurred and presented under general expenses in the consolidated statements of income and other comprehensive (loss) income.

A liability is recognised for benefits accruing to employees in respect of wages and salaries, annual leave and sick leave in the period the related service is rendered at the undiscounted amount of the benefits expected to be paid in exchange for that service.

bb. Share-based payments

Based on IFRS 2, a share-based payment of ICA, granted to executives, is classified as an equity instrument, and is recognized when the services are received by the Entity subsequently settled by delivering shares. The cost of equity an instrument reflects their fair value at the date of grant and is recognized in earnings during the period in which the executive rights to the benefit accrue.

The fair value determined at the grant date of the equity-settled share-based payments is expensed on a straightline basis over the vesting period, based on the Entity’s estimate of equity instruments that will eventually vest, with a corresponding increase in equity. At the end of each reporting period, the Entity revises its estimate of the number of equity instruments expected to vest. The impact of the revision of the original estimates, if any, is recognized in profit or loss such that the cumulative expense reflects the revised estimate, with a corresponding adjustment to additional paid-in capital.

cc. Revenue recognition

Revenues are recognized when it is likely that the Entity will receive the economic benefits associated with the transaction. Revenue is measured at the fair value of the consideration received or receivable and represents the amounts receivable for goods and services provided in the normal course of activities. Revenues are reduced for estimated customer returns, rebates and other similar allowances.

By type of activity, revenue is recognized based on the following criteria.

Construction Contracts

Revenues from construction contracts are recognized using the percentage-of-completion method based on the costs incurred method or the units of work method, considering total costs and revenues estimated at the end of the project, in accordance with IAS 11, Construction Contracts (“IAS 11”). The percentage-of-completion method provides an understanding of the performance of the project in a timely manner, and appropriately presents the legal and economic substance of the contracts. Under this method, revenue from the contract is compared against the costs incurred thereof, based on percentage-of-completion, which will determine the amount of revenue, expenses and income that can be attributed to the portion of work completed.

F-53

To use the percentage of completion method, the following requirements should be met: (i) the contract must clearly specify legal rights relating to goods or services to be provided and received by the parties, the consideration to be paid and the terms of the agreement, (ii) the contract must specify the legal and economic right to receive payment for work performed while the contract progresses, (iii) it is expected that the contractor and the customer fulfill their contractual obligations, and (iv) that, based on the budget and the work contract, they can determine the total revenues, the total cost to be incurred and the estimated profit.

The base revenue utilized to calculate the amount of revenue to recognize as work progresses includes the following: (i) the initial amount established in the contract, (ii) additional work orders requested by the customer, (iii) changes in the considered yields, (iv) the value of any adjustments (for inflation, exchange rates or changes in prices, for example) agreed to in the contract, (v) the decrease in the original contract value and agreements in contracts, (vi) claims and conventional penalties, and (vii) completion or performance bonuses, as of the date on which any revision takes place and is effectively approved by the customers.

The basis for costs used to calculate the percentage of completion in accordance with the costs incurred method considers: (i) costs that relate directly to the specific contract, (ii) indirect costs related to contract activity and that can be identified with a specific contract, and (iii) any other costs that may affect the customer under the terms agreed in the contract. Costs that relate directly to a specific contract include all direct costs as raw material, labor, costs of subcontracting, manufacturing costs and supply of equipment carried out in independent workshops, project startup costs and depreciation. Indirect costs that are assignable to the contract include: indirect labor, administrative payroll, housing camps and related costs, quality control and inspection, internal and external oversight of the contract, insurance costs, bonds, depreciation, amortization, repair and maintenance.

The costs which are excluded are: (i) general administrative expenses that are not included under any form of reimbursement in the contract, (ii) selling expenses, (iii) the costs and expenses of research and development that have not been considered reimbursable by the contract, and (iv) depreciation of machinery and equipment not used in the specific contract even when available for a specific contract, if the contract does not allow revenue for such concept. Additionally, costs for work performed in independent workshops and construction in-process are excluded until their receipt or use, and are recorded as assets until such time.

Periodically, the Entity evaluates the reasonableness of the estimates used in determining the percentage of completion. Estimates of the costs of construction contracts are based on assumptions which may differ from the actual cost over the life of the project. The cost estimates are reviewed periodically, taking into account factors such as increases in the prices of materials, amount of work to be performed, inflation, exchange rate fluctuations, changes in contract specifications due to adverse conditions, provisions that are recorded in accordance with construction contracts throughout the duration of projects, including those relating to penalty clauses, completion and commissioning of the projects and the rejection of costs by customers, among others. If, as a result of this evaluation, there are modifications to the revenue or cost previously estimated, adjustments are made for the percentage of completion and if there are indications that the estimated costs to be incurred to completion of the project will exceed the expected revenue, a provision is recognized for estimated contract loss in the period in which it is determined. Revenues and estimates costs may be affected by future events. Any changes in these estimates may affect the results of the Entity.

A variation on the extent of the work may be due to several factors, including: improvements in the construction process due to reduced supplies or runtime, local regulatory changes and changes in the conditions for the execution of the project or its implementation, design changes requested by the customer and the geological conditions not included in the original plan. Additionally, and in order to identify possible changes in contracts, ICA has implemented a method by which these changes can be identified and reported, the amounts can be quantified and approved and the changes can be implemented efficiently on projects. A variation is included in contract revenue when: a) it is probable that the customer will approve the changes and the amount of revenue resulting from the change, b) the

F-54

amount of revenue can be reliably measured and c) and it is probable that the economic benefits flow to the entity. Claims or incentives for early completion are recognized as part of the revenue of a contract, provided that there is sufficient evidence that the customer will authorize payment for these items. Consequently, claims and incentives are included in contract revenue only when: a) negotiations have reached an advanced stage such that it is probable that the customer will accept the claim, and b) the amount that probable to be accepted by the customer can be determined reliably. The costs incurred for change orders instructed by the client and are awaiting the definition and authorization of price, are recognized as an asset under the caption “Cost and Estimated Earnings in Excess of Billings on Uncompleted Contracts” described below. With respect to incentive payments, revenues are recognized only when the execution of the contract is significantly advanced to conclude that the specified standards of performance will be achieved or exceeded and the amount of the incentive payment can be measured reliably.

In projects financed by the Entity in which the value of the contract includes revenues from work execution and financing, only borrowing costs directly related to the acquisition or construction of assets, less any yield obtained by the temporary investment of such funds and the foreign exchange loss to the extent it is an adjustment to interest costs, are attributed to contract costs. Borrowing costs that exceed estimates and are not contractually reimbursed by customers are not part of the contract costs. In these types of contracts, the collection of the contract amount from the client may take place at the end of the project. However, periodic progress reports are presented to and approved by the customer, which form the basis for the Entity to obtain where appropriate, financing for the project in question.

When a contract includes the construction of several facilities, the construction of each is considered a separate profit center when: (i) separate proposals have been submitted for each facility, (ii) each facility has been subject to separate negotiations and the contractor and customer have been able to accept or reject that part of the contract relating to each asset, and (iii) revenue, costs and profit margin of each facility can be identified.

A group of contracts, whether with one or more customers, are managed as a single profit center if: (i) the group of contracts had been negotiated as a single package, (ii) the contracts are so closely interrelated that they are, in effect, part of a single project with an overall profit margin, and (iii) the contracts are performed simultaneously or in in a continuous sequence.

The Entity does not offset the profit and loss from separate profit centers. The Entity also ensures that when several contracts comprise a profit center, a combined result is presented.

Under the terms of various contracts, revenue recognized is not necessarily related to the amounts billable to customers. Management periodically assesses the reasonableness of its receivables. In cases where there are indications of difficulty of their recovery, estimates for doubtful accounts are recognized through results of the year they are determined. The estimate is based on the best judgment of the Entity under the circumstances prevailing at the time of determination, modified by changes in circumstances.

The line item “Cost and Estimated Earnings in Excess of Billings on Uncompleted Contracts” included in the heading of “Customers”, originates from construction contracts and represents the difference between the costs incurred plus recognized profit (or less any recognized losses) and less certifications made for all contracts in progress, in excess of the amount of the certificates of work performed and invoiced. Any amounts received before work has been performed are included in the consolidated statement of financial position as a liability, as advances from customers. Amounts invoiced from the performed work but not yet paid by the customer are included in the consolidated statement of financial position as billings on contracts and other receivables.

F-55

Infrastructure concessions

In accordance with IFRIC 12, for both financial concession assets and intangible concession assets, the revenues and costs related to construction or improvements during the construction phase are recognized in revenues and construction costs. Revenues stemming from the financing of the investment in concessions are recorded in the statement of income and other comprehensive income as they accrue and are presented in concession revenues within continuing operations.

Revenues from the operation of concession projects are recognized as concession revenues, as they accrue, which is generally at the time vehicles make use of the highway and pay the respective toll in cash or electronically at toll collection booths. Revenues are derived directly from users of the concession, or at times, from the grantor of the concession. Aeronautical services revenues consist of the right of use of airports (TUA), which are recognized when services are provided. Prices for the services rendered are regulated by the grantor. In concessions involving toll revenues, tariff revisions do not apply until their effective date of application.

Real estate sales

According to IFRIC 15, Agreements for the Construction of Real Estate and IAS 18, revenues derived from sales of low- and medium-income housing and real estate are recognized as revenue once the house or real estate development is completed and the rights, benefits and obligations related to the property have transferred to the buyer, which occurs upon formalization of the deed.

For sales of developments in which financial resources are obtained from financial institutions, revenue is recognized only when the properties are completed, the respective financing is received and the deed had been finalized. When the Entity provides financing, revenue is recognized upon the execution of the deed of delivery-receipt, which is the moment upon which the risks, benefits, rights and obligations of the property have been transferred to the buyer and only when is probable that the economic benefits associated with the transaction will flow to the Entity. The Entity retains neither ongoing management involvement in the property sold in the degree to which usually is associated with an owner, except for the reservation of title, which is released at the time the price has been paid in full and the deed is ultimately processed.

Real estate inventories are divided into two large segments: land held for development and inventories in-progress (which include both houses under construction and unsold finished houses).

Mining services

Revenues from the rendering of mining services are recognized based on the stage of completion based on the services contracted with and approved by the customer.

Interest income

Interest income is recorded on a periodic basis, with reference to capital and the effective interest rate applicable.

Leasing revenues

The Entity’s policy for recognition of revenue from operating leases is described in subparagraph (i) of this note (the Entity as lessor)

Revenue from services

Revenues from services are recognized when services are rendered.

F-56

Income from fair value

The fair value determined at initial recognition of assets acquired in a transfer, where the assets acquired will be utilized in the ordinary operations of the Entity, is recognized as income in the consolidated statement of results and other comprehensive income (loss).

dd. (Basic and diluted (loss) earnings per share

Basic (loss) earnings per share is computed over three levels of income, dividing: a) (loss) income from continuing operations attributable to the controlling interest, b) (loss) income from discontinued operations attributable to the controlling interest and c) the net (loss) income of the controlling interest, over the weighted average number of common shares outstanding during the year. The dilutive effect of the Entity’s potential ordinary shares does not have a significant material effect on the Entity’s determination of earnings per share; thus diluted (loss) earnings per share approximates basic earnings per share during the years ended December 31, 2015, 2014 and 2013.

5. Critical accounting judgments and key sources of estimation uncertainty

In the application of the Entity’s accounting policies, which are described in Note 4, management of is required to make judgments, estimates and assumptions about the carrying amounts of assets and liabilities. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

Estimates and assumptions are reviewed regularly. Changes to accounting estimates are recognized in the period in which the change is made and future periods if the change affects both the current period and to subsequent periods.

a. Critical judgments in applying accounting policies

The following are the critical judgments, apart from those involving estimations (see paragraph b), performed by management throughout the process of applying the accounting policies of the Entity and that have the most significant effect on the amounts recognized in the consolidated financial statements.

• Assessing whether material uncertainties exists that would cause doubt as to whether the Entity could continue as going concern, Note 2.a.

• Evaluation of the existence of control in subsidiaries, joint control or significant influence over investments in joint ventures and investments in associates (Notes 17, 18 and 19).

• The assessment of the circumstances and requirements for assets held available for sale (Note 34).

• Through December 31, 2012, for the determination of deferred taxes, the Entity prepared projections of future taxable income for period over which deferred taxes will reverse, in order to establish whether it expected to pay IETU or ISR in those years for purposes of determining the basis of the deferred income tax. The Entity noted that certain subsidiaries will only incur ISR, while others will only incur IETU; it had therefore recognized deferred taxes by using the basis applicable for each legal entity. As of January 1, 2014, IETU was eliminated, such that deferred income taxes are only recognized on an ISR basis (Note 28).

• The Entity’s defined benefit obligation is discounted at the rate set by reference to market yields at the end of the reporting period on government bonds. Significant judgment is required when setting the criteria for bonds to be included in the population from which the yield curve is derived (Note 39).

F-57

• The Entity is subject to transactions or contingent events over which professional judgment is exercised in developing estimates of probability of occurrence of probable outflows associated with adverse outcomes. The factors considered in these estimates are the legal merits of the case, as substantiated by the opinion of the Entity’s legal advisors.

b. Key sources of estimation uncertainty

The following are the key assumptions concerning the future, and other key sources of estimation uncertainty at the end of the reporting period, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year:

• Estimates of total construction contract revenues, costs and profits, according to the accounting for percentage of completion; and the determination of the responsibilities of the Entity relating to certain contingencies, including the result of pending work to be executed or future litigation, arbitration or other dispute resolution procedures relating to claims on contracts (Note 4.cc and 29).

The construction process of the Entity, apart from its technical and operating processes, have legal and economic aspects that require the Entity to determine the probability that the economic benefits related to claims for executed works will flow to the Entity, as follows:

Construction contracts in which the Entity participates are typically regulated by the legislation of various Mexican jurisdictions, which recognize the contractor’s right to receive payment for work completed. As a legal matter, the client owns projects in process and the contractor (e.g., ICA) is entitled to payment for these projects, even when payment might not occur until completion of the contract. Standard contract terms also establish the contractor’s right to receive payment for work completed. In addition, the Entity has internal procedures in place that uphold the requirements of completed projects for its clients, such as the construction logbook, approvals of the physical progress by the client’s supervisor, work contracts and, when necessary, addendums and/or modifications to the foregoing. The reconciliation and recognition of work performed, in addition to pricing, is a slower process which may extend beyond one year.

A significant portion of the Entity’s public sector contracts are executed with state governments or governmental institutions. The changes in the federal administration have led to changes in the administrations of these state institutions, which has notably slowed the approval process related to work performed.

The Entity believes that the potential credit risk related to construction contracts is adequately covered because the construction projects in which the Entity participates generally involve customers of recognized solvency, Note 7.e.

• In order to estimate doubtful accounts receivable, among other elements, the Entity considers the credit risk derived from the customer’s financial position and any significant collection delays based on the terms agreed in construction service agreements (Note 7.d).

• The realizability of real estate inventory (Notes 4.f and 10) and long-term accounts receivable (Note 7.c).

• Fair value of assets acquired in business combinations (Note 3.g).

F-58

• The management of the Entity assesses the recovery account long-term customers considering tolls, traffic, inflation, years of recovery, maintenance and an operation cost. The valuation of this account is based on the discount of future cash flows and is prepared annually (Note 7.c.).

• The long-lived assets of the Entity correspond to property, machinery and equipment and concessions granted by the Mexican government and foreign governments for the construction, operation and maintenance of roads, bridges and tunnels, airport management and municipal services. The Entity reviews the estimated useful life and depreciation and amortization methods used for tangible and intangible assets derived from concessions at the end of each reporting period and the effect of any changes in estimates are recognized prospectively. Annually, to assess any evidence of impaired assets, the Entity prepares a value in use calculation assigned to each cash-generating unit, in the case of certain assets. The estimate of value in use requires the Entity to determine future cash flows to be derived from the cash generating units and an appropriate discount rate to calculate the present value. The Entity uses cash flow projections of revenue based on estimates of market conditions, the calculation of prices and volumes of traffic (Notes 13 and 14).

• The Entity reviews the estimated useful lives and residual values of property, machinery and equipment at the end of each annual period. Based on the detailed analysis, Entity management makes modifications in the useful lives of certain property, machinery and equipment. The level of uncertainty associated with estimates of useful lives is related to changes in the market and use of assets because of production volumes and technological development (Note 13).

• Valuations for determining the recoverability of deferred tax assets and recoverable asset tax, using projections of future tax results, the primary estimate represented by the projection of revenues, costs and expenses for tax purposes (Note 28).

• The estimates made by the independent appraisers in determining the fair value of investment property (Note 15).

• In determining whether goodwill is impaired, the Entity makes an estimate of the value in use of the cash-generating units to which goodwill has been allocated. The value in use calculation requires that the Entity to estimate the future cash flows expected to arise from the cash-generating unit and a suitable discount rate in order to calculate present value (Note 16).

• Management prepares estimates to determine and recognize the provision necessary for the maintenance and repair of highways and other infrastructure under concession, which affects the results of the periods in which the infrastructure under concession becomes available for use and through the date on which the maintenance and/or repair work is performed. The Entity makes estimates to determine and recognize the provision for project completion, rental and maintenance of equipment, which is determined based on the degree of completion of projects and the hours of operation in the case of machinery. To determine certain provisions, the Entity uses factors related to lead times for construction contracts and production volume, as well as hours of use for owned and leased machinery (Note 23).

• The Entity values and recognizes derivatives at fair value, regardless of the purpose for holding them. Its bases fair value on market prices for derivatives traded in recognized markets. If no active market exists, the derivative instrument is valued using the valuations of counterparties (valuation agents) verified by a price provider authorized by the National Registry of Securities (Registro Nacional de Valores). These valuations are based on methodologies recognized in the financial sector and are supported by sufficient and reliable information, and consider credit risk. Techniques and methods of valuation of derivative financial instruments are disclosed in Note 26.

F-59

Although these estimates were made based on the best information available at December 31, 2015, it is possible that events may take place in the future that will require their modification (increases or decreases) in subsequent years, which such modification would be made prospectively in the Entity’s consolidated financial statements.

6. Cash, cash equivalents and restricted cash

7. Customers

a. As of December 31, 2015, 2014 and 2013, the balance of short-term customers is as follows:

	Deccember 31,

Total customer receivables from sales and services	Ps.	13,408,832		Ps.	18,442,771		Ps.	16,377,508

⁽¹⁾  As of December 31, 2015, includes accounts receivable by Ps.401 million pesos corresponding to the indemnity payment from the Directorate General of Civil Aviation, derived from the expropriation of land of Inmobiliaria Baja, S.A. de C.V. (“Inbaja”). Related income is presented in other income (expense) in consolidated statement of results and other comprehensive (loss) income, see Note 36.

⁽²⁾ Future cash flows of the Canal General, Tren Interurbano, Túnel Churubusco-Xochiaca and Boca del Río projects, which such projects had a balance of cost and estimated earnings in excess of billings on uncompleted contracts at December 31, 2015 of Ps.332,538, and had a balance of billings on contracts as of such date of Ps. 1,149 million, have been pledged as collateral for certain loans. On April 1, 2016, the related loan was repaid and pledge over the cash flows from these projects was cancelled, see Note 21.

Customer receivables are measured at amortized cost.

Management considers that the amounts recorded related to customer receivables reflects their fair value. No interest on current customer accounts receivable is charged. As of December 31, 2015, an increase in the allowance for doubtful accounts for current receivables was recognized for Ps.3,927 million, which corresponds mainly to the Barranca Larga, Terminal de Contenedores, and Corredor Norte projects, originated by the changes in circumstances during 2015 with regards to the previous year, which are described hereunder. Likewise, as is explained in paragraph (c) of this note, an increase in the allowance for doubtful accounts for long-term receivables was recognized for $1,454 million pesos (see Note 7.c), which corresponds to the projects of Río de los Remedios, Línea 12, and Distribuidor Vial Puebla. The total balance of allowance for doubtful accounts as of December 31, 2015, 2014, and 2013, amounted to Ps.6,672 million, Ps.1,457 million, and Ps.961 million, respectively, for both current and long-term receivables, determined based on the default experiences of the counterparty and an analysis of their current financial situation. During 2015, cancellation of costs and earnings in excess of estimated billings on uncompleted contracts was also recognized for Ps.420,211 (see Note 2.b). In addition to the customers mentioned in Note 41, no other customer represents more than 5% of the total balance of the accounts receivable of customers.

Barranca Larga

This project relates to a construction contract entered into by Ingenieros Civiles Asociados, S.A. de C.V. (“ICASA”) and Desarrolladora de Infraestructura de Puerto Escondido, S.A. de C.V., both subsidiaries of ICA, corresponding to the project granted under concession for the construction of the Oaxaca- Puerto Escondido highway, which is described in Note 13.h. The complex political, social, union, and communal situation in the State of Oaxaca has resulted in significantly lower construction

F-61

progress than what was originally planned, which has resulted in cost overruns, which comprise a portion of the amount included in the balance of costs and estimated earnings in excess of billings on uncompleted contracts as of December 31, 2015. These aforementioned political, social, union and communal issues have modified the economic aspects of the project originally estimated in the concession agreement and have originated expenses that translate into cost overruns related to construction activities. Negotiations are currently being carried out with the Ministry of Communications and Transportation (SCT) for the authorization and / or acknowledgment of the cost overruns generated in the project.

Considering the circumstances and status as of December 31, 2015 of this project mentioned in Note 13.h, the Entity does not believe that it is probable that it will recover the balance of costs and estimated earnings in excess of billings, coupled with the fact that their recovery will depend on the results of the negotiations carried out jointly (for both the construction company and concessionaire) with the grantor of the concession. As a result of the uncertainties surrounding amounts that could potentially be recovered, the Entity recorded a provision to the allowance for doubtful accounts for Ps.1,731 million, which represents the total balance of costs and estimated earnings in excess of billings of the project as of December 31, 2015.

Terminal de Contenedores

In July 2012, APM Terminals Lazaro Cardenas, S.A. de C.V. (“APMT”) and ICASA entered into a contract for the construction of the Terminal Especializada de Contenedores II (“TEC II”) in the port of Lazaro Cárdenas, Michoacán. During the project execution, several modifications were made to the scope requested by APMT, which increased the project timing and cost. Although requested by APMT, these changes were not acknowledged through a written modification of the contract with the customer at that time, these impacts were not recognized by the customer through of an amendment agreement to contract.

After a series of negotiations, in August 2015, a Memorandum of Understanding was executed that established the new dates for project milestones, which were included in the first modifying agreement that was excuted on September 11, 2015. On November 12, 2015, APMT and ICASA began negotiations with respect to additional changes in scope related to phase one of the project, as well as the disincorporation of certain other changes that would be agreed to in a second modifying agreement. The second modifying agreement established, among other things, that APMT would pay to ICASA U.S.$48 million, equivalent to Ps.832,310, derived from the works outlined in such modification, as part of the acknowledgment of the changes to the contract scope that APMT authorized, and U.S.$2 million equivalent to additional Ps.34,680, as incentive for performance on the dates agreed. Finalization of this agreement took place in the first week of December 2015, and it was agreed with APMT that, through the delivery of the performance bonds by ICASA related to an advance payment initially made by APMT and through the compliance by ICASA of its performance, the second modifying agreement would be executed.

On December 16, 2015, when ICASA communicated to APMT that it would deliver the performance bonds to proceed with the execution of the second modifying agreement, APMT reported unilaterally to ICASA, the termination of the construction contract.

Based on the terms set forth in the construction contract, further negotiations must begin, with the assistance of an independent engineer, who will determine the value of the works executed through the termination date. As of the date of this report, this process had not commenced, nor has there been any indication of the commencement of the negotiations between the parties. However, the Entity considers that even during construction, when negotiations between the parties with respect to contract changes took place and an independent engineer was involved, the results generally tended to favor APMT.

There does not appear to be certainty regarding the final amounts that may result from the negotiations nor a definitive date at to when such negotiations will take place, resulting in what the Entity believes are unfavorable results for ICASA. ICASA is analyzing the possibility of an arbitration process to submit the claims for the changes that APMT requested from project origin and that ICASA believes are not being negotiated fairly.

F-62

As a result of the above uncertainties, the Entity recognized an allowance for bad debts of Ps.959 million, comprising the balance of costs and estimated earnings in excess of billings for this project as of December 31, 2015, and Ps.50 million comprising the amount of withheld certifications. Additionally, as of December 31, 2015, there are Ps.108 million of construction inventories of which, according to the contract terms, APMT would be entitled to take for the conclusion of the pending works should contract termination actually occur. Therefore, the Entity has also recorded a reserve for obsolete inventories, see Note 9. The application of the balance of the advance payment received by APMT for Ps.367 million will depend on the result of the negotiations, for which reason this amount continues to be maintained as a liability in the consolidated statement of financial position as of December 31, 2015.

Corredor Norte

This project related to the contract for the construction of the highway, Phase II of the Corredor Norte Segmento el Golf – Tocumen (Lajas stretch – December 24th) in Panama, entered into by Ingenieros Civiles Asociados Panamá, S.A. (“ICAPSA”) and Ena Este, S.A. (“ENA”). During the construction process, cost overruns were generated for additional works and other concepts. In May 2015, ICAPSA delivered to ENA an acknowledgment request of additional costs, financing costs, amount of additional works, adjustments to the contractual sum, fair profit, and extension of the term for the project execution. ENA replied on October 28, 2015, stating its disagreement to the ICAPSA request. However, it indicated its intention to commence a liquidation process for 60-day term beginning from the date of their reply.

In spite of the aforementioned, the Corredor Norte Phase II was opened and started operations on October 15, 2015. ENA has not executed any substantial termination certificate, nor has it set forth any valid or legal argument that justifies its aforementioned posture nor its failure to comply with the contract.

On February 24, 2016, ICAPSA met with ENA to propose a reduction in the cost overruns originally submitted for the amount of U.S.$57 million, equivalent to Ps.988,369, to an amount that would at least allow ICAPSA to pay its obligations to creditors, suppliers, subcontractors, banks, factoring, of U.S.$35 million, equivalent to Ps.606,893. ENA stated that it is only willing to pay US$7 million, equivalent to Ps.121,379, of which it has already paid U.S.$4.5 million, equivalent to Ps.78,029, for these concepts, thereby only owing U.S.$2.5 million, equivalent to Ps.43,350.

As a result of the different postures between the parties, ICAPSA is assessing the possibility of submitting an arbitration claim. Once it is presented, ICAPSA will determine if there is a possibility that ENA may negotiate from its original proposal, otherwise ICAPSA will continue with the arbitration process.

The recovery of the amounts owed to ICAPSA will depend initially on the negotiations carried out with ENA, when the arbitration claim is filed. Considering the uncertainty of the final sum to be negotiated, and taking into account the circumstances that surround the project, as of December 31, 2015, the Entity recognized an allowance for doubtful accounts of U.S.$20 million, equivalent to Ps.347 million, representing 40% of the account balance of this customer at the end of 2015.

ICA’s principal customers are concentrated in the construction segment and represent 63%, 67%, and 67% of total consolidated revenues for the years ended December 31 2015, 2014 and 2013, respectively, see Note 41.

The management of accounts receivable and the determination of the need for a reserve are carried out by each individual entity that forms part of the consolidated financial statements, as each entity has more thorough knowledge of the financial situation and relationship with each of its customers. However, in each of the Entity’s lines of business, certain guidelines exist regarding specific characteristics that each customer must possess depending on the nature of the line of business. For foreign private clients, the Entity’s policy is to generally require payments in advance at the start of the project and routine collections on a short-term basis to allow positive working capital management.

F-63

b. Accounts receivable to customers include amounts that are past due at the end of the reporting period (see analysis below for aging), but for which the Entity has not recognized any allowance for bad debts since there has been no significant change in credit quality and the amounts are still considered recoverable. The Entity does not maintain any collateral or other credit enhancement on those balances, nor does it have the legal right of offset against any amount owed by the Entity to the counterparty.

Accounts past due, but not impaired, which are not considered in the allowance for doubtful accounts, are as follows:

	December 31,
	2015		2014		2013
Aged between 180 and 359 days	Ps.	1,527,590	Ps.	259,421	Ps.	648,487
Aged 360 days and thereafter		171,993		297,253		590,310
Total	Ps.	1,699,583	Ps.	556,674	Ps.	1,238,797

In accordance with the nature of the Entity’s activities, the industry in which it operates and its average credit terms, the Entity has determined that accounts receivable aged greater than 180 are considered past due. The following table indicates billed accounts receivable past due but not impaired of main projects at December 31, 2015, 2014 and 2013:

	Ps.	15,330,604		Ps.	16,434,967		Ps.	13,244,812

⁽¹⁾  As of December 31, 2015, 2014, and 2013, the balance includes Ps.11,871 million Ps.11,739 million, and Ps.11,126 million, which corresponds to the services agreement related to the public works and financed public works of the Río de los Remedios-Ecatepec highway, which Autopista Naucalpan Ecatepec, S.A.P.I. de C.V. (“ANESA”), a subsidiary of ICA, has executed with the Sistema de Autopistas, Aeropuertos, Servicios Conexos y Auxiliares del Estado de Mexico, (“SAASCAEM”). Amounts owed, including a guaranteed return on investment, as well as the guarantee of total investment made and related financing, will be made based on the tolls charged by the trust established for this purpose. Amounts are required to be paid until the investment is recovered, plus the guaranteed internal return rate of 10%. In March 2013, the third stretch of the highway started operations, which includes from Av. Vallejo to the Mexico- Pachuca highway. From that date, the stretch in operation, together with the first stretch (Puente de Vigas - A. Vallejo), represents a total length of de 12.1 kilometers. As of December 31, 2015, the three stretches of the Río de los Remedios-Ecatepec Highway have been operating for three complete years, generating actual toll data as well as historical evidence of the application of the resources managed by the Trust. It has also provided actual information related to periodic rate increases. Using this information, a discounted cash flow analysis was prepared at the end of 2015. Additionally, the inputs to the discounted cash flow model were reviewed, taking into account the operating experience of the highway in the last three years, the inflation rate reduction observed during the year, as well as more realistic rate increases based on the actual data accumulated. Based on its analysis considering actual results over the past three years, management decided to define a maximum recovery term of 60 years, even though pursuant to the construction contract, there is no stated term for the recovery of the account receivable. As a result, a provision for doubtful accounts was recognized for Ps.1,012 million, presented in cost of concession s in the statement of results and other comprehensive (loss) income.

⁽²⁾ As of December 31, 2015 and 2014, amounts are mainly comprised of Ps.3,745 million and Ps.506 million, and Ps.3,745 million and Ps.699 million of project Line 12 (see Note 29.c) and Autopista Rio de los Remedios, respectively. At December 31, 2013, the balance includes mainly Ps.848 million and Ps.696 million of Centro de Readaptación Social Nayarit and Autopista Rio de los Remedios, respectively.

d. The allowance for doubtful accounts, considering both current and long-term is comprised as follows:

Considering the existing economic outlook for the Entity at the end of 2015, the Entity assessed the balances of costs and estimated earnings in excess of billings on uncompleted contracts as well as their adequate classification and valuation. This assessment considered the analysis of the circumstances of each construction project. As of December 31, 2015, the Entity recorded an increase in the allowance for doubtful accounts related to various completed projects and other projects in process, when the circumstances and events indicated a deterioration in recoverability such that a conclusion was reached that there was virtually no certainty of recovery. As a result of the above, an increase in the allowance for doubtful accounts was recognized for Ps.5,381 million which Ps.4,369 million is presented in the cost of construction and Ps.1,012 million in the consolidated statement of results and other comprehensive (loss) income. Of the increase, Ps.3,927 million correspond to current accounts receivable, principally with respect to the projects described in paragraph (a) of this note, and Ps.1,454 million correspond to long-term accounts receivable, Ps.1,012 million for Río de los Remedios, see paragraph (c) of this note, Ps.166 million for Líne 12, and Ps.241 million for Distribuidor Vial Puebla. These last two projects are in legal proceedings with respect to their recovery.

Líne 12

As is mentioned in Note 29, during 2015 the Entity filed a new claim, through which it is demanding from the Federal District Government the payment of various concepts that were not included in the expert opinion, such as: pending estimates, maintenance works, rehabilitation of the tracks of the stretch Atlalilco - San Andrés, among others. In the analysis of the amount claimed, Ps.166 million were excluded because it is considered that there is a low probability of their recovery. Therefore, a corresponding provision to the allowance for doubtful accounts was recongized.

Distribuidor Vial Puebla

Considering the status of the lawsuit for the recovery of the account receivable, as of December 31, 2015, which is described in Note 29, including (i) actions carried out by the Government of the State of Puebla, in which did not appear at three reconciliation hearings to which it was summoned; (ii) during the period provided to the Government to respond, the lawsuit paperwork file was lost; and (iii) court delays have occurred, without indication of replacement dates, management has determined that there is a low probability that it will recover all amounts owed under this project and has recognized an allowance for doubtful accounts for Ps.241 million, a portion of the amounts receivable.

e. The cost and estimated earnings in excess of billings on uncompleted contracts is originated by construction contracts, as mentioned in Notes 4 (cc) and 5.b and represents the difference between the costs incurred plus recognized profits and / or less recognized losses and less certification amounts of work performed and billed on uncompleted contracts, as a result of applying the percentage of completion method of accounting for construction revenues. Requirements exist that must be met before billing of the cost and estimated earnings in excess of billings on uncompleted contracts, which

F-66

are established in the billing terms defined in each of the contracts. Furthermore, the billings of change orders and claims are subject to the reconciliation of work, definition of the prices and the final resolution between the parties.

The Entity believes that the amounts of cost and estimated earnings in excess of billings on uncompleted contracts are current according to the status of projects, the documentation that supports the work performed, the progress of negotiations with the customer to reconcile balances for works such as additional works and contract changes, and the characteristics of its operation. Although costs and earnings in excess of billings may be outstanding for more than 365 days, based on the characteristics of the operation, the Entity believes that it is able to collect within the normal course of its operations, given that most often, balances are greater than one year as a result of changes and modifications to the original contract, which are negotiated and approved by the customer. However, they usually have to go through various reconciliation and administrative processes which may take more time than originally estimated. The Entity believes that its classification as current is appropriate. The Entity classifies these receivables as long-term only when collection is contractually agreed to be long-term or when the amounts are in a legal recovery process. For example, during 2014, the Entity assessed the legal status of the accounts receivable related to the Line 12 and Distribuidor Vial Puebla projects, for Ps.3,745 million and Ps.519 million respectively (Note 29), concluding that the resolution of these claims is probable to occur over a period longer than 12 months, a situation that remained at the end of 2015. The above conclusion led to the reclassification of accounts receivable of these projects from current to long-term in 2014. Based on management estimates, the allowance for doubtful accounts of costs and estimated earnings in excess of billings on uncompleted contracts is sufficient.

At December 31, 2015, 2014 and 2013, the composition of the cost and estimated earnings in excess of billings on uncompleted contracts, according to the date it was recorded, is as follows:

	December 31,
	2015		2014		2013
0 to 90 days	Ps.	1,796,060	Ps.	4,523,189	Ps.	1,911,816
91 to 360 days		5,175,645		3,489,923		3,839,977
More than 360 days		5,344,871		4,670,328		5,966,132
		12,316,576		12,683,440		11,717,925
Plus:
Long-term		5,151,474		5,540,996		1,561,133
Total cost and estimated earnings in excess of billings on uncompleted contracts	Ps.	17,468,050	Ps.	18,224,436	Ps.	13,279,058

The cost and estimated earnings in excess of billings on uncompleted contracts includes revenue related to claims. For determining the probability of recovery, the Entity considers factors such as the evaluation of law, collections received to date and its experience with the related customer. The recovery of these items can take more than a year, depending on whether the matter can be resolved directly with the customer or litigation or arbitration is necessary. When new information becomes available that indicates a change in the recoverable amount, an adjustment is made to the allowance which is recognized in results in the period in which the change occurs.

In the long-term balance of cost and estimated earnings in excess of billings at December 31, 2015 and 2014, there are balances of approximately Ps. 4,410 million and Ps.4.264 million, respectively, subject to pending litigation or dispute resolution procedures, as described in Note 29. Balances therein reflect the best estimate of management regarding the probability of recovery of the amount of claims in dispute, considering such factors as the evaluation of law, collections through the reporting date and experience with the related customer.

In the determination of the above calculation, the revenues and account receivable of the project Río de los Remedios are excluded, as is described in paragraph (c) above. This project corresponds to a service agreement related to the public works and financed public works of the Río de los Remedios-Ecatepec Highway. The collection of this account includes a guaranteed return on investment, as well as recovery of the investment made by the Entity and all the related financing. As the collection of this account is expected to be over the long-term and the revenues of this construction contract are recorded on an annual basis, it was concluded that if the effects of this construction contract were not excluded in the determination of the age of customers, the financial ratio would be distorted. Therefore, in the calculation of the financial ratio, the revenues recorded in the years that ended December 31, 2015, 2014, and 2013, as well as the balance of the account receivable at December 31, 2015, 2014, and 2013 of Río de los Remedios were excluded.

To determine the age of customers, the balance of costs and estimated earnings in excess of billings on uncompleted contracts is included, because the numerator of the financial ratio considers total revenues, which includes amounts related to this concept that form part of this balance.

Additionally, in the calculation of the age of customers, the balance of the current portion of the financial asset from concessions is also included, which is presented in other accounts receivable (see Note 11) of the Rioverde, Sarre, and Papagos projects (see Note 13), because the revenues generated are included in the total revenues considered in the financial ratio.

8. Construction backlog

a. Backlog includes the entire contract amount only for contracts in which ICA has control over the project. ICA considers that it controls a project when it has a controlling interest and it is the project leader. When control is shared, the amount included in backlog represents ICA’s equity participation in the backlog of the association. A reconciliation of backlog representing executed construction contracts at December 31, 2015, 2014 and 2013 is as follows:

	Civil Construction			Mining Services			Other Services		Total

⁽¹⁾ Ps.5,986 million corresponds to the incorporation of Facchina, see Note 3.g, and Ps.853 millions to the Barranca Larga project.

⁽²⁾ Corresponds to the deconsolidation of San Martin, see Note 2.c.

⁽³⁾ Includes the Monterrey VI Aqueduct project for Ps.4.688 millon, which as of the date of this report, has not initiated operations (see Note 18).

b. When the control is shared, backlog incorporates the portion of the contract belonging to ICA based on its rights to the assets and obligations for the liabilities, as defined by IFRS 11. The principal activity of the Entity is focused on the construction segment. Backlog, in millions of pesos, in which ICA participates through its joint ventures (see Note 19) is as follows:

	Total associates and joint ventures
	(Million pesos)
Proportion of ownership held by ICA at December 31, 2013	Ps.	10,864
Balance at September 30, 2014 (1)	Ps.	25,216
New contracts and updates in 2014		26,849
Exchange rate adjustment		426
Construction revenue earned 2014		(8,570	)

Construction revenue earned 2015		(27,981	)
Balance at December 31, 2015		65,366
Proportion of ownership held by ICA	Ps.	32,163

(1) Starting in the fourth quarter of 2014, the segment information delivered to the Executive Committee of ICA includes the financial and operating performance information of the ICA Fluor joint venture (Note 19). This change occurred in ICA’s internal reporting because of the importance of industrial construction business for the Entity, the relocation of ICA Fluor’s shares to ICA Civil Construction, and because it is part of the strategic development goals of ICA. Therefore, the Administration of the Entity considers ICA Fluor as a reportable segment and has separately presented the information of ICA Fluor in its segment information. Because of this, the disclosure of backlog from associates and joint ventures is included from that date, see Note 41.

9. Construction materials inventories

Construction materials inventories are as follows:

	December 31,
	2015			2014		2013
Raw materials and other materials	Ps.	660,096		Ps.	592,706	Ps.	655,291
Parts, accessories and other		78,994			360,228		282,336

Recognized impairment		(195,469	)		—		—
	Ps.	543,621		Ps.	952,934	Ps.	937,627

Based on the economic outlook of the Entity at the end of 2015, management of the Entity analyzed the balances of construction material inventories for their adequate valuation. As discussed in Note 7, Ps.108 million were impaired because of the status of the Terminal de Contenedores project. Additionally, for balances aged greater than 120 days, the Entity estimated an impairment of Ps.87 million. These impairments are presented in costs of construccion n the statement of results and other comprehensive (loss) income.

10. Real estate inventories

a. Short-term real estate inventories consist of the following:

	December 31,

Short-term real estate inventories	Ps.	835,171	Ps.	1,467,037	Ps.	2,075,582

F-72

b. Capitalized financing costs are Ps. 621 million, Ps.551 million and Ps.457 million, as of December 31, 2015, 2014 and 2013, respectively.

c. During 2015, the Entity recorded an adjustment to decrease the inventory to its net realizable value of Ps.1,040 million, presented in cost of goods sold in the statement of results and other comprehensive (loss) income, for which the inventory is ultimately valued at Ps.1,123 million. The balance at December 31, 2014, was Ps.1,838 million. This real estate inventory guarantees one of the Entity’s bank loans of U.S.$40 million with a fixed interest rate of 7.5% and maturing in July 2016 (see Note 21).

At December 31, 2014, the balances of vertical projects include the following: The Entity acquired through an auction, a property in foreclosure, at a price of U.S.$49 million dollars, which includes land and buildings (foundations for the construction of three towers in Panama). Management of the Entity considered this investment as part of its long-term real estate inventory, as based on the conditions of its location; the Entity considered that it would be able to develop the property in the future, in the normal course of its operations. The Entity considered that the price paid at the public auction was not representative of the fair value of the property, considering principal markets, defined by IFRS. Consequently the purchase price of the property acquired was adjusted to fair value on initial recognition, which was determined according to an appraisal; the characteristics and location of the property were considered. The adjustment was for Ps.1,099 million, and were presented in fair value on initial recognition of real estate inventory in the consolidated financial statement of results and other comprehensive (loss) income in 2014.

The fair value in 2014, was determined based on the market comparable that reflects recent transaction prices for similar properties, adjusted for specific characteristics related to the Entity’s property, obtained through market research by different media, direct visits to comparable properties and mass-media.

⁽¹⁾ During 2015, the Entity reviewed the real estate inventories and their adequate valuation. This assessment considered commercial demand, density increase aspects, current and projected prices, available financing, and other variables and circumstances that may imply changes in the future business model currently followed by the Entity. As of December 31, 2015, the Entity recorded an impairment to the net realizable value of real estate inventories, associated with development projects, when the circumstances and events indicated a potential impairment and the net proceeds from any expected sales were s lower than the carrying value of such projects. These estimates are derived from the sales forecasts, the current economic outlook, the current business plan, and the ongoing restructuring plan. The impairment amounted to Ps.1,560 million pesos, which is presented within cost of goods sold in the statement of results and other comprehensive (loss) income.

⁽²⁾ During the last quarter of 2014, the Entity initiated certain activities to sell their real estate inventories to the Entity’s suppliers, specifically one of its vertical housing projects; this resulted in an adjustment to the carrying value of the inventory. At December 31, 2014, its carrying value is Ps.265 million pesos.

e. The vertical and horizontal housing has the following characteristics:

The vertical housing consists of multi-level houses built on common property, with rights of ownership to the common property, but for which in contrast to the horizontal property described below, does not result in a community of owners.

Vertical growth architecture offers different activities within a common property area, where mixed land use is obtained. The challenge provided by vertical architecture is to generate the best use of the common property.

A vertical development integrates as many possible uses of the common areas for people who reside there, and provides vegetation in spaces that would normally be occupied by a horizontal housing development and provides low density.

Horizontal housing is characterized by extended private property on one floor or locale of a building or urban or complex construction. Horizontal housing is a legal institution that refers to the set of rules governing the division and organization of various properties, as a result of the segregation of a building or common ground. The horizontal property is a mixture of private property and co-ownership. It is a form of division of property by dividing housing into condominiums, and attributes to the holder of such units an absolute and exclusive right of ownership over the property as well as a right of ownership regarding property in common domain.

The horizontal housing is a regime that regulates the way in which a property is divided, the relationship between the owners of private property and common assets that have been segregated of a land or a building. The horizontal housing allows the organization of the co-owners and maintenance of the common areas.

The right of horizontal property includes a percentage of ownership in the common elements of all apartment owners in the condominium.

f. At December 31,2015, 2014 and 2013, certain real estate inventory valued at Ps.1,360 million, Ps.985 million and Ps.1,448 million, respectively, are pledged as collateral for loans outstanding totaling Ps.872 million, Ps.1,015 million and Ps.898 million, respectively (see Note 27).

g. Tourism and real estate projects of Ps. 1,142 million, Ps.1,145 million and Ps.1,110 million as of December 31, 2015, 2014 and 2013, respectively, corresponds to development Aak-Bal. In November 2014, it began operating the first phase of this resort.

Concession projects are generally financed with long-term debt without recourse to shareholders, which are mainly guaranteed by the cash flows generated by the related concession, project resources and assets, receivables and contract rights. When cash flow is the main guarantee for the payment of the debt, funds are not freely disposable to shareholders until compliance with certain conditions are met, which are assessed annually.

Additionally, the Entity provides and maintains reserve accounts during the term of the related loan, usually corresponding to six months of debt service, which are not available to the concessionaire. These funds are for debt service, in the event that the cash flows generated by the concession are insufficient.

h. Below is a description of the primary concessions held by the subsidiaries of the Entity:

Grupo Aeroportuario Centro Norte (“GACN”)

The concessions granted by the SCT have a term of 50 years from November 1, 1998, concession agreements to manage operate and where appropriate, build and maintain the following international airports: Acapulco, Ciudad Juarez, Culiacan, Chihuahua, Durango, Mazatlan, Monterrey, Reynosa, San Luis Potosi, Tampico, Torreon, Zacatecas and Zihuatanejo. As these airports are state-owned, after the termination of the concession period, any improvements and additional installations permanently attached to the concessioned assets and created during the concession period will revert to the state.

The Entity is obligated to carry out maintenance, improvements to concessioned assets and acquire fixed assets according to the master development program. The master development program for 2016-2020 is Ps. 4,446 million based on December 31, 2014 values and Ps.4,640 million based on December 31, 2015 values, updated using the National Producer Price Index (NPPI) excluding oil, according with the concession contract, which is anticipated to be as follows:

Year	Amount
2016	Ps.	1,352,412
2017		1,297,204
2018		986,513
2019		606,428
2020		397,605
	Ps.	4,640,162

From the 2011-2015 master development program with an amount of Ps. 3,418 million updated to December 31, 2015, the remaining amount is Ps. 20,612 thousan; corresponding to construction at the Acapulco and San Luis Potosí airports for Ps.11,943 thousan and Ps.8,669 thousan, respectively. These amounts are a product of savings made from the investments in such airports. The proposal made by the Entity to use such savings in other investments was, as of December 31, 2015, in the process of authorization by the Mexican Bureau of Civil Aviation. The cost of airport improvements recognized by the Mexican Bureau of Civil Aviation that form part of the Entity’s investment in the concession are “recovered” by the Entityin the form of adjustments to the maximum rates that the Entitymay charge for aeronautical services, which are regulated by the Mexican Bureau of Civil Aviation.

In 2009, the Entity paid Ps.1,160 million to acquire land strategically located adjacent to the Monterrey airport to allow for the airport’s future growth, including the construction of a second runway, which the Entity intends to complete in the future. The acquired land is classified in the Entity’s financial statements for the year ended December 31, 2015, 2014 and 2013 as land owned by the Entity at its acquisition value, presented as a fixed asset. The Entity is negotiating the ability to recognize the cost of the investment made on this land as part of its future investment in the Monterrey airport concession included in the airport’s required master development program investments, rather than as a fixed asset owned by the Entity.

F-80

The DGAC approved the recognition of Ps.386,538, value date of December 31, 2009, Ps.461,159 to restated value at December 31, 2015 with the INPP according to the concession contract, the land acquired as part of the Entity’s investment in concession included in the MDP at the Monterrey airport for the period from 2013 to 2015.

Of the Ps.386,538 thousand authorized by the DGAC, Ps. 121,701 thousand were authorized for recognition as investment in concession by the Entity in 2013, Ps.138,486 for 2014, and Ps.126,351 thousand were authorized for 2015. An additional amount of Ps.77,306 was authorized by the DGAC through the extraordinary review of the maximum rate in 2011. The Entity is still negotiating for the recognition as investment in concession of the remaining cost of the land acquired, for the amount of Ps.695,769. All amounts in this paragraph are expressed in nominal at December 2009 pesos. The current amounts to be recognized by the DGAC as part of the investment in the concession will be adjusted based on the INPP.

The land acquired by the Entity is the exclusive property of the Entity and are classified in the consolidated statement of financial position as part of property and equipment. The land will remain classified as a fixed asset until negotiations with DGAC have been concluded. If the DGAC recognizes the land as part of the concession, it is expected that title thereto will transfer from the Entity to the Mexican government, at which point the Entity would derecognize the fixed asset and recognize a corresponding addition for the same amount as part of the investment in airport concessions (intangible assets).

Acapulco Tunnel (“TUCA”)

In May 1994, the Government of the State of Guerrero (the “State Government”) granted, to one of the Entity’s subsidiaries, a 25-year concession for the construction, operation and maintenance of a 2.947, kilometer tunnel connecting Acapulco and Las Cruces. The concession term started in June 1994. In November 2002, the Congress of the State Government of Guerrero approved the extension of the concession term by 15 years because the actual volume of usage was lower than the amount foreseen by the terms of the concession agreement.

Toll revenues provided by this concession guarantee a long-term debt agreement which matures over 25 years (see Note 27).

Rio Verde - Ciudad Valles - Highway (“RVCV”)

In July 2007, the SCT granted the Entity a concession for the highway between Rio Verde and Ciudad Valles covering a length of 113.2 kilometers for: (i) operation, maintenance upgrade, conservation and extension of the Rio Verde — Rayon highway of 36.6 kilometers; (ii) construction, operation, maintenance and conservation of the Rayon — La Pitaya II highway of 68.6 kilometers; and (iii) operation, maintenance upgrade, conservation and extension of the La Pitaya — Ciudad Valles III highway of 8.0 kilometers. The concession term is for 20 years.

In August 2014, the term of the concession was extended 20 years and the maturity of the PPS contract was extended 4 years, such that the term of the concession will end in 2047 and the PPS contract will end in 2031.

At December 31, 2014, the road sections mentioned above have begun operations.

At December 31, 2013, accumulated financing cost amounted to Ps.336 million. The annual average capitalization rate was 5.25%.

Kantunil- Cancun - Highway

In December 1990, the SCT granted a concession to Mayab Consortium, S.A. to build, operate and maintain 241.5 kilometers of road, which connects the cities of Kantunil and Cancun in the states of Yucatan and Quintana Roo. The concession term is for 30 years. The first stretch of highway came into operation in December 1991.

During the third quarter of 2011, the Entity signed an amendment to the concession which adds to the terms of the concession the construction, operation, conservation and maintenance of an additional 54 kilometers related to the Kantunil-Cancun highway to Playa del Carmen. This additional highway project will connect Lazaro Cardenas with the Playa del Carmen municipality, which would be a branch of the toll road from Cancun to Merida. It is estimated that the additional 54 kilometers, which began construction in January 2012, will have two phases: 7 km into the municipality of Solidaridad (Playa del Carmen) and another 47 kilometers into Lazaro Cardenas, which will have two lanes, one for each direction of 3.5 meters each with a width of 2.5 meters; with a right of way of 40 meters and a maximum speed of 110 kilometers per hour. The first section, called Cedral-Tintal, will begin at the Trunk Cedral junction, which connects with Kantunil Highway in the town of Lazaro Cardenas, bound for Playa del Carmen; while the beginning of the branch-Playa del Carmen Tintal be built in the second grade-separated junction- called Tintal junction-, that the project will also connect with the toll road Merida-Cancun.

The term of the concession is extended 30 years, terminating in 2050.

In November 2014, the Playa del Carmen on the Kantunil-Cancun highway tranche began operations.

Toll revenues provided by this concession guarantee the redeemable participation certificates that will be amortized over a 17 year period (see Note 27).

At December 31, 2014 and 2013, accumulated financing cost amounted to Ps.255 million and Ps.117 million, respectively. The annual average capitalization rate was 5.23% and 5.83%, respectively.

Libramiento La Piedad - Highway (“LIPSA”)

In March 2009, the SCT granted to the Entity’s subsidiary, Libramiento ICA La Piedad, S.A. de C.V., the concession to construct, operate, conserve and maintain the Libramiento de La Piedad (La Piedad Bypass), which is 21.388 km long and includes the modernization of the federal highways 110 and 90, for a length of 38.8 km and 7.32 km, respectively, located in the States of Guanajuato and Michoacan. The Libramiento de La Piedad will form part of the major junction joining the highway corridors of Mexico City-Nogales and Queretaro-Ciudad Juarez and will free the city of La Piedad from the long-haul traffic moving between the Bajio region and Western Mexico. The concession term is for 30 years. The construction period concluded in November 2012, date on which operations of the concession began.

In 2013, the concession was financially restructured, which originated the modification of the concession to extend its term for an additional term of 15 years, therefore, the term of the concession conclude in 2054.

At December 31, 2013, accumulated financing cost amounted to Ps.145 million; the annual average capitalization rate was 10.93%.

Barranca Larga – Ventanilla - Highway

In January 2009, the SCT granted to DIPESA a concession for the construction, operation, use and maintenance of the Barranca Larga – Ventanilla highway, in the state of Oaxaca, with a length of 104 kilometers. Total investment of the project is approximately Ps.5,352 million. The concession term is for 30 years.

The new highway will provide a fast connection between the tourist development of Huatulco and Puerto Escondido on the Pacific coast and the capital of the state of Oaxaca. The new four-lane highway will decrease travel time from Oaxaca to Puerto Escondido by approximately 100 minutes.

The previous owners of DIPESA did not obtain the necessary financing for the construction of the highway. Therefore, on March 23, 2012, the first amendment to the concession was executed, whereby the date of completion of construction was changed to 24 months after the date of the start of construction (May 31, 2012). Accordingly, construction was expected to conclude on May 2015.

At December 31, 2015, 2014 and 2013, accumulated financing cost amounted to Ps.555 million Ps.328 million and Ps.139 million, respectively. The annual average capitalization rate was 12.55%, 13.19% and 12.69%.

Project status

During 2014, the Entity’s was able to contribute capital to the project in a timely and adequeate maner. However, during the second and third quarters of 2015, the Entity’s capital contributions to the project were affected by its lack of liquidity, which worsened in the fourth quarter of 2015.

Additionally, from the beginning of the project, the Entity experienced problems related to the rights of way with the surrounding communities. Although a resolution was expected during 2015, the issue was not resolved and the entire central zone of the highway (San Francisco) was blocked, preventing access to any works, nor was it possible to cross via the rights of way. The situation worsened and in the last 2 years, there were 62 events documented before the SCT (of a total of 96 events of different types and dimensions of blockage by the surrounding communities). These events directly affected the construction development, generating cost overruns.

Additionally, as a result of ICA’s liquidity problems during 2015, mainly in the third quarter of the same year, the Entity was unable to make sufficient capital contributions to the project. Likewise, credit lines the Entity was negotiating in order to try to raise financing for the project were ultimately not approved. The events, coupled with the aforemention social problems which were not imputable to the Entity, resulted in ICA requesting a third modification to the project schedule, requesting to extend the construction period until October 2016. As of the issue date of these financial statements, a response to this request has not been given.

According to the second modification, the project’s construction phase should have been completed in December 2015. Due to the aforementioned factors, management assessed the uncertainty in the recovery of the total investment included in the concession intangible, and determined an impairment existed of Ps.2,209 million, resulting in a net investment remaining of Ps.1,547 million, representing the value of capital contributed, as well as financing resources invested in the project.

As of the date of issue of these fiancnail statements, the project is operating at a minimal level, and ICA is engaged in negotiations with FONADIN to analyze the options for a financial restructuring of the project and obtain the necessary resources for its completion.

Palmillas - Apaseo El Grande

In February 2013, the SCT granted a concession to build, operate, conserve and maintain the Palmillas —   Apaseo El Grande highway. The cost of construction is approximately Ps.5,366 million. The 4-lane, 68-kilometer, high specification highway, located between the states of Queretaro and Guanajuato, creates a new connection between the metropolitan area of Mexico City, the Bajio region and the North. The highway will provide greater flow of traffic around the city of Queretaro that will reduce traffic, will improve environmental conditions and road safety. The total investment will be approximately Ps.9,550 million. The plan is to complete the construction of the highway at the second quarter of 2015. The concession term is for 30 years.

At December 31, 2015, 2014 and 2013, accumulated financing cost amounted to Ps.818 million, Ps.448 million and Ps.194 million, respectively. The annual average capitalization rate was 12.56% and 11.31%, respectively.

d. Description of effective control in San Martin

Since October 1, 2015, the financial statements of San Martin were no longer consolidated in financial statements of ICA, see Note 2. As of that date San Martin became an investment in associate and is accounted using the equity method.

Through September 30, 2015, management assessed whether ICA had control over San Martin based on its ability to make unilateral decisions regarding the relevant activities of San Martin. As part of its judgment, management considered the rights of non-controlling interest holders, as well as its own potential voting rights with respect to call options that are included in the shareholders’ agreement. After such analysis, management concluded that ICA had the ability to direct the relevant activities of San Martin and therefore has control. Potential voting rights are considered substantive because they can be exercised at the time that there is a potential disagreement regarding a decision related to the relevant activities of the Entity and their exercise price would be at fair value.

e. Changes in ICA’s ownership interests in GACN

As of December 31, 2015, 2014 and 2013, Aeroinvest holds directly 20.78%, 23.80% and 24.68%, respectively, of the capital GACN, which is listed on the stock exchange in Mexico and New York. Aeroinvest also directly owns 74.5% of the share capital of the entity Servicios de Tecnología Aeroportuaria, SA de CV (“SETA”) which in turn owns 16.70% of the capital stock of GACN. The control group of ICA, being the major shareholder of the Entity and related party thereof, also directly owns 6.07% of capital stock of GACN.

As mentioned in Note 2, in August 2015, Aeroinvest sold 12,081,300 shares of GACN, which is equivalent to 3.02% of its investment in GACN. The sale resulted in a gain, net of taxes, of Ps.545 million. In December 2014, Aeroinvest sold 3.5 million shares of GACN, which equivalent to .87% of its investment. Additionally, in July 2013, Aeroinvest sold certain of its shares of GACN in a secondary public offering (the “Offering”). As a result of the Offering, the shareholding of the Entity in GACN decreased from 54.37% to 37.12%. The sale resulted in a gain of Ps.1,015 million. The gains generated on disposal of shares described above, are reported in consolidated statements of changes in stockholders’ equity because ICA retains control of the subsidiary, for which reason such sales are considered a transaction between shareholders.

The capital structure the principal shareholders of GACN, as of December 31, 2015 is as follows:

	Number of Shares						Percentage of Issued and Outstanding Capital
	B Shares		BB Shares		Total shares		B Shares			BB Shares			Total shares
Aeroinvest (1)		83,121,400				83,121,400		20.78	%		—			20.78	%
SETA		17,034,000		49,766,000		66,800,000		4.26	%		12.44	%		16.70	%
Control group		23,618,410				23,618,410		5.90	%		—			5.90	%
Public		226,460,190				226,460,190		56.62	%					56.62	%
						400,000,000								100.00	%

⁽¹⁾ In the first quarter of 2016, Aeroinvest merged with CONOISA, prevailing CONOISA in its capacity as surviving entity; therefore, it assumes the rights and obligations of the merged entity. The merger shall take legal effect in June 2016.

During 2015, 9,034,000 Series BB shares were converted to Series B shares.

At December 31, 2015, 68,679,398 shares of GACN owned by ICA guarantee various bank loans as described in Note 27. On December 29, 2015, the Entity entered into default on interest payments on one of its loans, for which reason the related bank exercised its guarantee over the shares of GACN held by ICA, see Note 42. Additionally, 7,287,068 shares of GACN are pledged as a guarantee (without transmission of possession) for certain letters of credit for the Acapulco Diamond Tunnel (Note 13.h) and Mitla Tehuantepec (Note 19.b) projects.

F-92

After the execution of the aforementioned guarantees, Aeroinvest’s participation in GACN is 14.32%, considering the indirect participation of SETA. As of the date of these financial statements, the Entity continues to maintain control over the GACN and continues to consolidate its results and operations.

The relevant activities of GACN that significantly affect its returns and that the Entity controls through Aeroinvest, among others, include: negotiation of airline, passenger and cargo services contracts and the related fees, to the extent unregulated fees associated therewith, and fees within the maximum tariff approved by the government; management and oversight of GACN’s airport concessions and allocation and distribution of profits of GACN or subsidiaries.

GACN’s bylaws establish that the major decisions of GACN, including the determination of business strategy and budget are entrusted to the GACN board of directors (the “Board of Directors” or “Board”). The affirmative vote of the directors appointed by SETA is required for major decisions of GACN including the election of the chief executive officer of GACN, approval of GACN’s management structure and any amendments thereto, approval of the business plan and the investment budget on an annual basis, including master development plans for airports, entry into material financing arrangements and execution of material asset acquisitions and sales.

GACN’s Board of Directors is comprised of a minimum of 11 members, considering that a minimum of 25% of members must be independent. In accordance with Mexican securities law, each shareholder with 10% equity has the right to nominate a director. The Series BB shareholders (SETA) are entitled to nominate three directors, of which two are appointed by Aeroinvest. Aeroinvest as the holder of a direct 20.78% of the shares of GACN can appoint two directors, and an additional director together with the control group of ICA. The remaining five members are appointed by majority vote at the general meeting of shareholders of GACN. At December 31, 2015, there is only one shareholder participation of 6%, the rest is dispersed, for which reason it is unlikely agreement among them would be reached with respect the election of members of the Board.

At December 31, 2015, the majority of directors were, designated by the Entity at the shareholders meeting held on April 2015, either directly or through its affiliates, as a result of shareholdings prior mentioned. Pursuant to the current bylaws of GACN in existence as of such date, once the Board members are elected, they remain on the Board for one year unless removed due to death or incapacitation, resignation, applicable law or termination by 51% (excluding the three SETA-appointed directors) of voting shares pursuant to Article 15 thereof. Because under Article 25 of the GACN bylaws, none of the other current shareholders had the right to call a meeting for a period of one year, such that Aeroinvest by having appointed a majority of the Board, effectively controlled the Board and major Board decisions as of December 31, 2015.

The Entity considers that the following are other factors that indicate their “de facto” control over GACN:

• Aeroinvest holds significant appointment rights with respect to management of GACN, including the ability to appoint the CEO, the chief financial officer (“CFO”), the general counsel, and the human resources manager of GACN. The Entity considers this is further evidence of de facto control by their over GACN.

• The majority of the members of the investee’s governing body are related parties of the Entity. Of the 11 members of GACN’s Board, six of them in 2014 were also members of the Entity. One is the current CEO of the Entity, and one is a current Vice President. Additionally three members of GACN’s Board were formerly of the Entity’s board, two of which were previously Executive Vice President and CEO of the Entity. In addition, the current GACN CFO was previously employed with the Entity.

Exposure to variable returns - With regard to variable returns of GACN, Aeroinvest has exposure through (i) its 20.78% equity investment in GACN, (ii) its ability to declare GACN dividends, which may be issued by favorable vote of a simple majority of the series BB shares (of which Aeroinvest

F-93

owns 74.5%), and (iii) the remuneration that SETA receives for services provided to GACN under a technical assistance and technology transfer contract, under which Aeroinvest, through SETA, is paid fees that vary based on GACN’s annual operating profit.

Considering the analysis and elements described above, management has concluded that ICA possesses the power to direct the relevant activities of GACN and subsidiaries, at December 31, 2015. Accordingly, ICA continues to consolidate GACN in its consolidated financial statements, under IFRS 10. However, it will continue to evaluate its ability to consolidate under argument of facto control in the consolidated financial statements of 2016.

Nevertheless, the decrease in the percentage of participation of ICA in GACN resulted in the deconsolidation of GACN by ICA for tax purposes during 2013, as required by Mexican Income Tax Law, see Note 28.

During 2015, 2014 and 2013, GACN made capital repayments and dividends to non-controlling interest for Ps.749,952, Ps.703,560 and Ps.496,492, respectively.

Derived from the financial and operational restructuring that the Entity began during the last quarter of 2015, a provision for restructuring expenses was recognized, which principally includes the estimated cost of reducing staff and external consultant’s fees. The provision for restructuring expenses includes only the direct expenditures arising from the restructuring and does not include costs associated with the continuing operations of the entity. This provision is presented in the caption other (income) expense in the consolidated statements of results and other comprehensive (loss) income, see Note 36.

The provision related to costs expected to be incurred at the end of the project refers to costs that are originated under construction projects it will incur through the time the projects are finished and ultimately paid for by the customer. Such amounts are determined systematically based on a percentage of the value of the work completed, over the performance of the contract, based on the experience gained from construction activity.

Due to the nature of the industry in which the Entity operates, projects are performed with individual specifications and guarantees, which require the Entity to create guarantee and contingency provisions that are continually reviewed and adjusted during the performance of the projects until they are finished, or even after termination. The increases, applications and cancellations shown in the previous table represent the changes derived from the aforementioned reviews and adjustments, as well as the adjustments for expiration of guarantees and contingencies.

The Entity recognizes a provision for the costs expected to be incurred for major maintenance, mainly at airports, which affect the results of periods from the commencement of operation of the concession, until the year in which the maintenance and/or repair work is performed. This provision is recognized in accordance with IAS 37 and IFRIC 12. A portion is recorded as short-term and the remainder as long-term depending on the period in which the Entity expects to perform the major maintenance.

The provision for litigation is recognized in accordance with the analysis of the related lawsuits or claims, according to opinions prepared by the legal advisers of ICA. The Entity does not derecognize provisions until final resolutions are obtained and the payment process has begun, or there is no further doubt with respect to the associated risk.

The provision for repairs and maintenance of machinery under lease agreements is accrued based on the estimated hours used. The provision is used to cover the expenses related to maintenance, spare parts and repairs for return of the asset to the lessor in accordance with the terms of the lease agreement.

26. Derivative financial instruments

a. Financial instruments for trading and hedging purposes

As of December 31, 2015, ICA had outstanding approximately Ps.11,177 million in notional amount of derivative financial instruments for hedging and Ps.36 million in notional amount of derivative financial instruments for trading purposes. The Entity enters into derivative financial instruments to hedge the exposure to the interest rate risk and exchange rate risk of foreign currency related to the financing of construction and concession projects. The Entity’s policy is not to enter into derivative instruments for purposes of speculation.

There are no significant differences in the financial market risk to which the aggregated portfolios of derivative financial instruments are exposed.

Derivative financial instruments as of December 31, 2015, 2014 and 2013 are composed of instruments that hedge interest and exchange rate fluctuations.

The estimated amount expected to be recycled to results in 2016 is Ps.526 million.

The values shown in the “Received” column are as of December 31, 2015.

⁽¹⁾ Weighted average rate for the amount of the three derivatives of this project.

As of May 9, 2016, date of the last available accounting close, the fair value of these instruments has not fluctuated significantly.

RVCV

On December 3, 2008 the Entity entered into an interest rate swap in order to modify the profile of interest payments on a variable rate credit loan related to this project. Through the contract the Entity receives the 28-day TIIE rate paid on the credit loan and agrees to pay a fixed rate of 9.65% plus the applicable margin in the period of construction of 1.80%. At December 31, 2013 and 2012, this swap was designated as a cash flow hedge for which fluctuations in fair value are presented in other comprehensive income. In 2014, because of the early payment of the bank loan mentioned in Note 27, this derivative instrument was discontinued and it was recognized in financial expenses in consolidated statements of results for Ps.179 million.

LIPSA

In January 2010, an interest rate swap was entered into to fix the project financing rate. With this instrument, a floating interest rate of the 28-day TIIE is received and a fixed interest rate of 8.59% is paid. As of December 31, 2013 and 2012 it was considered a hedging derivative and its fair value fluctuations are presented in other comprehensive income. On February 16, 2011, the derivative was restructured to conform to the terms of the project. Additionally, in April and August 2011, two interest rate swaps were contracted to conform to the terms of the project by reducing the fixed rate to

F-116

a weighted average rate of 7.35%. In 2014, because of the early payment of the bank loan mentioned in Note 27, this derivative instrument was discontinued and it was recognized in financial expenses in consolidated statements of results for Ps.72 million.

Palmillas

In September 2013, an interest rate swap was entered into to fix the project financing rate. With this instrument, a floating interest rate of the 28-day TIIE is received and a fixed interest rate of 6.92% is paid. As of December 31, 2013, it is considered a hedging derivative and fair value fluctuations are presented under other comprehensive income.

During 2014, the ratio of changes in valuation of derivatives / changes in the primary position, from one period to another, exceeded the range stipulated by the standard (80% -125%), resulting in the suspension of hedge accounting. Accordingly, the effect in results was Ps.242 million, which represents the differences in provisions of project flows, because of failure to release the right of way.

In December 2015, the financial instrument was restructured as result of renegotiating the primary position considering 88% of drawdowns, based on the future cash flows from construction progress of the project. The restructuring consisted in adjusting the cash flows of the instrument to the actual provisions of debt. As a result of these modifications, effectiveness tests fell within the acceptable range specified by IFRS. Accordingly, the Entity reactivated hedge accounting. The renegotiation resulted in a payment of Ps.24 million, which was recorded in other comprehensive loss in equity.

Aeroinvest

In January 2013, an interest rate swap was entered into to fix the rate of the loan. With this instrument, a floating interest rate of the 28-day TIIE is received and a fixed interest rate of 5.16% is paid. As of December 31, 2014, this IFD is considered a negotiation derivative.

Sensitivity analysis

A sensitivity analysis was performed considering the following interest rate scenarios: +100 basis points, +50 basis points, +25 basis points, -25 basis points, -50 basis points -100 basis points. This analysis reflects the potential gain or loss of each derivative financial instrument depending on the position that it was in at the end of December 2015, providing an overall effect on the portfolio of instruments that the Entity maintains, with the intent of reflecting static scenarios that may or may not occur.

Sensitivity analysis

For the main instruments included in paragraphs b and c above, a sensitivity analysis was performed considering the following interest rate scenarios: +100 basis points, +50 basis points, +25 basis points, -25 basis points, -50 basis points - 100 basis points. Additionally, the following changes in the exchange rates and for the share price (SETA) were considered for each of the above scenarios: -100 cents, -50 cents, -25 cents, +25 cents, + 50 cents and +100 cents. This analysis reflects the potential gain or loss of each derivative financial instrument depending on the position that it was in at the end of December 2015, providing an overall effect on the portfolio of instruments that the Entity maintains, with the intent of reflecting static scenarios that may or may not occur.

ICA

At December 31, 2015, ICA held the following derivative financial instruments:

• During 2015, derivative financial instruments described in the following paragraphs were terminated early. The amount received on the date of settlement was comprised of accrued interest through the date of the instrument was early-terminated, plus interest to be accrued based on the agreed-upon maturity. The former were recorded in financial expenses in the consolidated statement of results and other comprehensive (loss) income while the latter were recorded in other comprehensive loss. Because the hedged item has not yet been recycled to results, the effects recorded in other comprehensive (loss) income will be recycled via amortization at the same time as the related hedged item. The effect recorded in results for the year ended December 31, 2015, amounted to Ps.485 million corresponding to interest accrued through early-termination date plus Ps.35 million included in other comprehensive loss. As of December 31, 2015, the balance in other comprehensive loss is Ps.380 million, net of deferred tax.

• In May, June and July of 2014, the Entity entered into five Cross Currency Swaps (CCS) with maturities of five years, in order to mitigate the exchange rate risk of the bond coupons on ICA’s Senior Notes of U.S.$700 million. The CCSs hedge a notional of U.S.$600 million. The maximum level sets an exchange rate of Ps.12.884 pesos per U.S.$1.00 in two of the instruments and Ps.12.910, Ps.12.925 and Ps.12.975 pesos per U.S.$1.00 in the other three and a fixed rate of 9.43 % in two of the instruments, and 9.62%, 9.58% and 9.6% in the other three. A fixed rate is paid in Mexican pesos in exchange for receiving interest in a foreign currency used to pay the interest of the coupons to the holders of the bond. During 2015, these instruments were terminated early.

F-120

• In February 2011, the Entity entered into four Cross Currency Swaps (CCS) with maturities of six years, in order to mitigate the exchange rate risk of the bond coupons on ICA’s Senior Notes of U.S.$500 million. The maximum level sets an exchange rate of Ps.12.055 per U.S. dollar at a fixed rate of 9.95%. A fixed rate is paid in Mexican pesos in exchange for receiving interest in a foreign currency, used to pay the coupons to the holders of the bond. During 2015, these instruments were terminated early.

• In August 2012, the Entity entered into three CCSs with maturities of three years, in order to mitigate the exchange rate risk of the interest payments on ICA’s Senior Notes of $350 million. The maximum level sets an exchange rate of Ps.13.30 per U.S. dollar at a fixed rate of 8.66%. During 2014, the CCS which covered US$200 million was discontinued because of the prepayment of this ICA Senior Note. During 2015, these instruments were terminated early.

These instruments were designated as hedging instruments at the time they were entered into and fluctuations in the fair value are presented in other comprehensive (loss) income.

• In June 2012, the Entity entered CCSs in order to mitigate the exchange rate risk. The primary position of this instrument is contractual obligations denominated in Peruvian new soles. The fixed exchange rate is Ps.5.2543 per new Peruvian soles. The instrument was liquidated on its maturity date.

• Paragraph e) of this Note, includes an option with market value as of December 31, 2013, of Ps.63,887, which corresponds to the transaction described below: on May 22, 2012, ICA, as buyer, signed a contract with Banco Santander, as seller, for a purchased call (the “Call”) to give ICA the right to purchase 22,280,100 of its shares at an average strike price of Ps.24.99, maturing on August 21, 2013. On the same date, ICA signed another contract with Banco Santander for a written put, allowing Santander to put to ICA (the “Put”) the same number of shares at the same average strike price and same maturity. The realization of the Call and Put was subject to a schedule of maturities agreed at the time of the contracts, to be applied during the contract period. Settlement of both the Call and the Put were physical or in cash, a determination that would be made three days before the instruments were exercised.

At December 31, 2012, the value of the instrument was recognized as a liability of Ps.6 million, a charge to equity of Ps.75 million less deferred income taxes of Ps.23 million, and a corresponding gain recognized in results of Ps.69 million.

In August 2013, the instrument was restructured. The modification consisted of an extension of the term of the instrument until February 2014 and a change in the strike price. This modification, subsequent valuations and the exercise of a portion of the instrument in 2013 resulted in a value of the instrument at December 31, 2013 of Ps.64 million in assets, Ps. 132 million in issued common stock, and Ps.68 million charged to results.

Beginning November 2013 and until February 2014, ICA fully exercised the instruments, repurchasing 22,013,000 of its own shares resulting, in a net gain of Ps.77 million (Ps.23 million in 2013 and Ps.54 million in 2014.

⁽¹⁾ In December 2015, a cross-default occurred on this loan as a result of the failure of the Entity to pay interest of approximately U.S.$ 31 million corresponding to its U.S.$700 million Senior Notes also described in this note; accordingly, this debt is presented as current debt in consolidated statements of financial position at December 31, 2015.

b. The scheduled maturities of long-term debt as of December 31, 2015, are presented in Note 30.

c. As of December 31, 2015, the Entity has credit lines with financial institutions as follows:

Credit lines:
Amount awarded	Ps.	19,203,876
Used		11,086,491
Available to use (1)	Ps.	8,117,385

⁽¹⁾ Includes credit line in UDI 95,256,361, equivalent to Ps.512,591, awarded to Rio de los Remedios project, maturing in July 2037 and interest rate of 10%. As of 31 December 2015, no dispositions have been made.

d. Long-term debt issued by some Entity’s subsidiaries includes various covenants that restrict the ability of certain subsidiaries of the Entity to incur additional indebtedness and capital lease obligations, issue guarantees, sell fixed and other non-current assets and make capital distributions to ICA, as well as require compliance with certain other financial ratios. These financial ratios include: the ratio of total liabilities to equity; the ratio of current assets to current liabilities; the ratio of current assets less affiliated accounts receivable to current liabilities; and the ratio of operating earnings plus depreciation to net financing expenses. The covenants of the debt contracts only restrict the resources stemming from project related to the loan and generally they do not limit the operations of the related subsidiaries. In addition, some of the long-term bank loans contain cross-defaults upon a default of the Senior Notes issued by ICA.

For the years ended December 31, 2014 and 2013, the Entity and its subsidiaries were in compliance with such covenants.

e. As mentioned in Note 2, due to the liquidity problems experienced by the Entity, which worsened in the last quarter of 2015, ICA management elected to use its resources mainly for its business operations and project execution rather than for paying the coupon interest of its U.S.$700 million Senior Notes with maturity in 2024, for the amount of U.S.$31 million that were due at the end of the month of December in 2015.

As a result of defaulting on this interest payment, cross defaults occurred in certain other long-term bank liabilities, which in certain cases; the related guarantees were enforced by the bank creditors in

F-132

the first months of 2016. By virtue of the above, these loans and the Senior Note liabilities for the amount of Ps. 30,937,234, after fees and financing expenses, were reclassified to the short-term liabilities in the consolidated balance sheet of the Entity as of December 31, 2015.

f. The Entity has issued guarantees to its subsidiaries for loans totaling Ps.6,582 million (see Note 29.k).

28. Income tax

ISR – The rate was 30% for the years 2015, 2014 and 2013, and under the new Income Tax Law 2014 (2014 Income Tax Law) will continue at 30% for 2016 and subsequent years. The Entity incurred ISR on a consolidated basis through 2013 with its Mexican subsidiaries.

IETU – Beginning in 2014, the flat tax was eliminated. Accordingly, the Entity was subject to, and recognized, IETU through December 31, 2013, which is a tax based on cash flows from both income and deductions and certain tax credits in each year. The rate was 17.5%.

As opposed to ISR, the parent and its subsidiaries incurred IETU on an individual basis.

Tax Reform 2014

In December 2013, Congress approved the Mexican Tax Reform that included elimination the flat tax (“IETU”) and the tax consolidation regime. As a result of the elimination of the IETU, the Entity cancelled the deferred IETU in its consolidated financial statements. Regarding the tax consolidation regime, a desconsolidation option was established for groups which consolidated under such regime, and provided three alternatives for calculating the deferred tax at December 31, 2013, as well as a fractional payment scheme during the next five years.

The Entity has the obligation to pay the tax related to the deconsolidation that was deferred in 2007 and earlier fiscal years. This in accordance with Section XVIII of transitional ninth article of the 2014 Tax Reform, and because ICA was a holding company through December 31, 2013 and as of this date was subject to the payment schedule contained in section VI of article four of the transitional provisions of the Income Tax Law published in the Official Gazette of the Federation on December 7, 2009, or Article 70-A of the Income Tax Act 2013 which was subsequently abrogated by Tax Reform 2014 (“2014 Law”). The tax was determined from the date of deconsolidation and will be payable according to the options provided in the 2014 Law and over a 10-year period beginning in 2014, according with the tax reform of 2009, discussed below.

Tax Reform 2009

In December 2009, modifications were published to the Income Tax Law (“2009 Tax Reform”) effective as of 2010, which establish that: a) the payment of ISR on benefits received from tax consolidation of subsidiaries, obtained in the years 1999 through 2004, must be made in partial installments from the year 2010 until 2014 and b) the tax on benefits obtained from the tax consolidation of subsidiaries for 2005 and subsequent years will be paid during the sixth through tenth years after that in which the benefit was obtained. The payment of the tax on the dividends distributed between companies that consolidated for tax purposes, made in years prior to 1999, could also be required to be paid in some cases, as established in tax provisions, such as upon sale of the shares of the controlled companies or at the time the Entity eliminates the tax consolidation regime, among others

Based on the above, as of December 31, 2015, 2014, and 2013 the tax payable for deconsolidation totaled Ps.4,251 million, Ps.4,411 million and Ps.4,588 million, respectively, and Ps.102 million of IMPAC, see paragraph (e) of this Note.

Asset Tax (IMPAC)

From 2008, the IMPAC Law was eliminated; however, in certain circumstances, recovery of IMPAC paid in the ten years immediately preceding that in which for first time ISR is paid is permitted, in the terms of the law.

F-133

Optional Regime for Groups of Companies

The Entity elected to be in the new optional fiscal integration regime for group companies beginning in 2014, as permitted by the 2014 Law, having presented the appropriate notice to the tax authorities. The main features of this regime are: (i) a minimum controlling interest of 80% in the voting shares of integrated companies is required by the integrating entity, (ii) it allows the deferral of a portion of income tax up to three years, establishing strict controls of current income tax and paid at the individual level, (iii) tax loss carryforwards from integrated or integrative companies which belong to previous periods may not be incorporated into the regime; only tax loss carryforwards which are generated from the effective date of the change in the tax law may be incorporated into this regime, (iv) an integrating factor is determined which is applied by all companies in the group, individually, to determine the income tax payable, and the deferred income tax over three years.

Through December 31, 2013, current income tax was based on the greater of ISR and IETU. Additionally, as of December 31, 2013, only deferred ISR is calculated, as a result of the elimination of IETU.

⁽¹⁾ During 2015, with the contraction of the construction industry and the appreciation of the U.S. dollar, principally, the Entity experienced a reduction in its revenues, which thereby directly impacted the generation of tax earnings that would allow the Entity to benefit from the amortization of its accrued tax losses. Notwithstanding, in the same year, in the framework of the third Presidential Address of the President Enrique Peña Nieto, announced the implementation of several initiatives to promote the economic development of the country. One of those initiatives is the creation of the “FIBRA E” as a new investment vehicle, which will allow public and private investors to monetize assets that have predictable and stable cash flows, under a tax program that reduces the tax levels and allows distributions. The FIBRA E represents an alternative investment substantially similar to the Master Limited Partnerships (MLPs) placed in the American market since 1981.

Among the exclusive activities to create the FIBRA E, there are investment projects in infrastructure, implemented through concessions, among others: i) roads, highways, railroad tracks, and bridges, ii) drinking water, drainage, sewage, and wastewater treatment, in accordance with the initiative announced.

ICA is eligible to create and apply the FIBRA E benefits, and until the last quarter of 2015, the projections indicated that the earnings generated through this mechanism would produce sufficient tax earnings to amortize the accrued tax losses. However, the default on interest payments related to the unsecured financial debt of the Entity, related to the three corporate bonds with expiration in 2017, 2021, and 2024 mentioned in Notes 27 and 42, as well as the default of certain obligations contained in other loan contracts with financial institutions as a result of cross-defaults (see Notes 27 and 42), make it unfeasible for the Entity to establish this FIBRA E mechanism. Notwithstanding the above, when the current operating and financial restructuring process is completed, the Entity believes it will have the possibility to implement the FIBRA E mechanism.

Tax losses to be amortized have been excluded from the determination of deferred tax assets as of December 31, 2015, originating the cancellation of deferred income tax assets for Ps.5,750 million. From a fiscal standpoint, the Entity maintains its right to amortize these losses, which depending on the result of each related entity, have duration between 6 and 10 years.

For the years ended December 31, 2015, 2014 and 2013, (loss) income before income taxes of foreign subsidiaries is Ps.(1,587) million, Ps.1,256 million and Ps.35 million, respectively.

⁽¹⁾ At December 31, 2015, 2014 and 2013, the Entity recognized a deferred tax asset of Ps.3,993, million, Ps.6,582 million and Ps.4,283 million, respectively, tax loss carryforwards of subsidiaries. Management has the expectation of applying such benefits in accordance with projections of taxable income in the related entities coupled with tax strategies with expected favorable outcomes.

e. Tax consolidation:

Changes in the income tax liability resulting from fiscal deconsolidation are as follows:

				December 31,
	2015			2014			2013
Beginning balance	Ps.	4,411,697		Ps.	4,588,523		Ps.	4,901,137
Increase in liability for tax consolidation		(61,267	)		(93,174	)		1,604,860
Unused tax losses in tax consolidation		—			—			(1,643,502	)
Inflation		88,660			172,941			—
Payments		(187,985	)		(256,593	)		(273,972	)
Total income tax payable for deconsolidation		4,251,105			4,411,697			4,588,523
Current income tax payable for deconsolidation		(1,228,380	)		(182,509	)		(260,236	)
Discount of tax liability by deconsolidation, arising from definition of specific time to payment		(405,268	)		(530,633	)		(675,000	)
Non-current income tax payable for deconsolidation	Ps.	2,617,457		Ps.	3,698,555		Ps	3,653,287

The income tax at December 31, 2015 on the tax consolidation will be paid as follows:

Year	Deferred ISR
2016	Ps.	1,228,380
2017		369,905
2018		454,204
2019		679,518
2020		588,678
2021-2024		930,420
	Ps.	4,251,105

However, the Entity did not make the 2016 payment which was due on March 31, 2016, in the amount of Ps.325 million. This originated the automatic enforceability of income tax payable for the years 2007, 2008 and 2010, amounting to Ps.903 million. Therefore, this amount was reclassified to current income tax payable as of December 31, 2015. Therefore, the current liability for tax deconsolidation at the issuance date of this report amounts to Ps.1,228 million as disclosed in the table above.

As of December 31, 2013, a liability for IMPAC of Ps.101 million was recognized, which was cancelled during 2014 by certain tax provisions effective from this year. Additionally, the IMPAC asset recorded of Ps.95 million was also eliminated accordingly.

F-139

f. The benefits from tax loss carryforwards, for which a deferred ISR asset has been recognized, can be recovered under certain circumstances. Expiration dates and restated amounts as of December 31, 2015 are:

Year of	Tax loss
Expiration	carry forwards
2017	Ps.	7,396
2018		99,270
2019		191,607
2020		589,972
2021		47,398
2022		976,574
2023		2,772,589
2024		1,266,156
2025		10,262,440
	Ps.	16,213,402

Additionally, each concession has received the approval of the Mexican Tax Authorities to amortize the tax losses until they are exhausted, the term of the concession has been completed or the concessions have been liquidated. The total amount of tax loss carry forwards from concessions which do not have an expiration date is Ps.9,035 million.

g. Certain tax loss carry forwards that can be used to offset future taxable income were not included in the determination of deferred tax of 2015, because the Entity believes it is not likely to recover are for Ps.24,836 million. Expiration dates and restated amounts at December 31, 2015, are as follows:

Year of	Tax loss
Expiration	carry forwards
2016	Ps.	407,897
2017		738,835
2018		330,574
2019		576,007
2020		590,115
2021		2,767,458
2022		3,177,405
2023		1,052,322
2024		8,479,693
2025		6,715,963
	Ps	24,836,269

As of December 31, 2015, the Entity assessed the probability for recovery of these tax loss carry forwards; based on its analysis, it determined that it is not probable that sufficient taxable profits will be available to allow approximately Ps.19,166 million of tax loss carryforwards to be recovered. Accordingly, the Entity did cancelled Ps.5,750 million of deferred income tax assets. However, from a fiscal standpoint, the Entity maintains its right to redeem this tax loss, which have a term ranging between 6 and 10 years, see subsection (a) of this Note.

F-141

29. Contingencies

a. Lawsuits and litigation - At December 31, 2015, there are several labor issues against many of the Entity’s subsidiaries in process, arising in the ordinary course of business. The Entity’s management and legal advisers expect that, given their nature, the resolutions of these lawsuits and claims will not represent a significant economic effect and will not have a significant effect in the consolidated financial statements in the years of resolution of these matters, either individually or as a whole.

b. Tax lawsuits - As of the date of these financial statements, ICA and certain of its subsidiaries are in the process of settling several tax disputes before the relevant authorities. Given that these disputes relate to the return or recovery of taxes paid by the Entity’s subsidiaries before filing such claims, the Entity does not expect to pay any additional amounts in the event it does not obtain favorable resolutions of such matters.

c. Labor Trials – There are several ongoing labor trials, filed against the various subsidiaries. Considering their nature, and even collectively, they do not represent a significant economic impact, because in the vast majority of the trials a conciliatory agreement is reached with the workers, in amounts equivalent to 30 and 45 days of wage. The amounts could be of 10 to 20 thousand pesos, and in those cases where the entire process is exhausted, agreements are reached to cancel up to 50% of their value.

d. Reorganization Trials – As of the date of these financial statements, no reorganization legal proceedings have been filed against any ICA Entity.

e. Construction

Línea 12 del Metro

1.a) Collection civil suit

On December 14, 2012, ICA, – together with its partners Carso Infraestructura and Construccion, S.A. de C.V. (“CARSO”), and Alstom Mexicana, S.A. de C.V. (“ALSTOM”) (collectively with ICA, the “Consortium”) –, filed a civil lawsuit against the Federal District Government (“GDF”), the Federal District Secretary of Works and Services, and the deconcentrated body called the Federal District Subway Project.

The above was derived from the collection of additional and extraordinary works outside the scope of the Lump Work Agreement No. 8.07 C0 01 T.2.022, executed on June 17, 2008, for the execution of the Mexico City Subway Line 12 Project.

The benefits demanded were the payment of the amount of Ps.3,835 million, plus the value-added tax and the amount of Ps.118 million, for the concept of financial expenses caused by the delay in the payment of work estimates, in addition to the delinquent interest, legal expenses and costs generated throughout the trial duration.

As far as ICA is concerned, the benefits claimed amount to the sum of Ps.2,691 million, plus the value-added tax.

On April 23, 2013, the judge appointed to hear the lawsuit decided not to order a study based on the merits of the case because, in his opinion, a prior administrative procedure should have been performed, albeit without affecting the petitioner’s procedural and substantive rights once this administrative instance has been concluded. The parties therefore settled their differences through an out-of-court procedure to resolve certain technical and administrative issues.

F-142

Within the conciliation procedure, more specifically the hearing held on December 13, 2013, the parties jointly filed a proposal to resolve their discrepancies with the Internal Control Entity, which essentially consisted of each party accepting the report issued by an expert witness appointed and approved by both parties, provided it was free from errors, fraud or bad faith. Likewise, the agreement expressly noted that the proposed solution was the only feasible way to resolve technical and administrative discrepancies and that there was no other dispute between them.

On January 16, 2014, the expert witness appointed by the parties delivered its reports and conclusions to the GDF and Consortium in accordance with the agreement of December 13, 2013, which determined an amount of Ps.2,247,913 owed to the Consortium. However, the GDF refused to fulfill the terms of this agreement.

On May 9, 2014, the Consortium filed an ordinary civil lawsuit at the federal court level against the GDF to request the formalization and fulfillment of the agreement of December 13, 2013 by the GDF and, as a result, the settlement of the amount of Ps.2,247,913 plus ancillary government charges which, through December 31, 2014, are estimated at Ps.398,000.

Of the amounts discussed in the immediately preceding paragraph, 81.39 % is receivable by ICA. At the date of this report, management considers that it has sound legal arguments to enable it to recover the claimed amounts; it estimates that this process will take more than 12 months.

Through the ruling issued on February 25, 2015, the Judge accepted the aforementioned legal action and served a summons to the GDF on March 3, 2015. The deadline for the GDF to reply to this summons ended on March 18, 2015.

After several jurisdictional challenges concerning the venue of the Federal Courts that should resolve the proceeding as well as proper lawsuit integration, the proceeding is currently in its final evidence submittal stage.

On April 15, 2016, the file was referred for sentence issuance, which the Entity considers will be favorable to the interests of the Consortium. Therefore, the Entity believes that it is probable that it will recover the amounts it is owed.

In addition to the aforementioned lawsuit, the Consortium filed two additional lawsuits as well as two other pending lawsuits discussed below, through which it is demanding from the GDF the payment of various items that were not included in the expert opinion, such as: pending estimates, maintenance works, refurbishing of the tracks Atlalilco - San Andrés stretch, social effects, among others, for the total amount of Ps.575,736.

On February 18, 2016, the Consortium filed a federal ordinary civil lawsuit against the GDF for the amount of Ps.346,979, related to amounts owed to the Consortium from the GDF for the execution of contract 022, which does not consider the execution of additional works and / or extraordinary works.

Also, on February 18, 2016, the Consortium filed a claim against the GDF for having to manage several social issues related to the Line 12 construction. The GDF and the Consortium entered into a debt acknowledgement agreement, which resulted in an amount owed by the GDF in favor of the Consortium for Ps.63,360.

The Entity believes it has sufficient documentary evidence of the amounts it is owed and as such, has high probabilities of recovering its accounts receivable.

The filing of two claims is pending, of which the notary payment requirements have been made to the GDF, and which consist of the following:

F-143

1.1.a) For concept of various activities and works related to maintenance of Line 12, not considered in the Public Work Contract 022, and in the Agreement of December 13, 2013, and which activities were performed at the direction of the GDF, generating a charge in favor of the Consortium for Ps.133,853.

1.2.b) For concept of various activities and works related to the Line 12 refurbishment, different from those considered in the Contract 022 and in the Agreement of December 13, 2013, which were performed at the direction of the GDF, generating a charge in favor of the Consortium for a credit of Ps.31,543.

As of April 15, 2016, these latter claims have not been filed yet, because it was necessary to wait 30 business days from the date when the notary payment request was made to the GDF. The Entity believes it will submit these claims in mid 2016.

1.b) Local Declarative Action filed by GDF

On April 24, 2014, the GDF filed an ordinary civil proceeding (“Declarative Action”) against ICA, CARSO, and ALSTOM individually.

In this claim, the GDF intends to obtain a legal judgment that determines that the work contract related to the Line 12 was executed under the “lump sum” modality and that for this reason, no modification to the amount and execution period is founded, and accordingly, evade the payment obligation of any additional work that the Consortium might demand. In this lawsuit, the GDF is not demanding any amount.

In March 2015, this lawsuit was at the evidence submission stage. However, it does not imply a direct economic contingency to the Entity because a declaratory action is exclusively intended to obtain a legal ruling regarding the proposed concepts rather than to obtain an economic settlement.

It is important to highlight that among the challenges posed by the Consortium was the lack of jurisdiction of the Local Courts to hear the issues related to the Contract 022, because if federal resources had been involved, the federal legislation was applicable and, consequently, the Federal Courts would be the appropriate venue.

As the Federal District Civil Judge confirmed its jurisdiction, the Consortium appealed to the refusal of jurisdiction acceptance. Therefore, the Civil Room that learnt of this appeal resolved in favor of the Consortium, stating that it is federal jurisdiction.

For reason of this resolution, the GDF promoted an “amparo”, which was denied. With this sentence, the GDF filed a revision recourse, which should have been resolved by a Collegiate Court, but was adopted by the Supreme Court of Justice of the Nation. The resolution is pending.

On March 12, 2015, Judge 61 issued sentence in the Declarative Action in favor of the GDF. Both the GDF and the Consortium filed an appeal, which was resolved by the Civil Court, favoring the GDF again. Therefore, both the GDF and the Consortium filed again an amparo trial, which resolution is pending by a Collegiate Court. As of April 15, 2016, this process is suspended until the lack of jurisdiction is resolved by the Supreme Court of Justice of the Nation.

1.c) Contract Settlement and Acquittal Process.

In September 2014, the Consortium presented an indirect amparo claim against the imminent unilateral contract settlement and acquittance by the GDF through which, the GDF intended to impose certain economic penalties for supposed work shortages or works executed improperly, as well against the unconstitutionality of article 57 of the Federal District Law of Public Works.

F-144

By virtue of the above, the Sixteenth Judge of District in Administrative Matters granted to the Consortium the final suspension so that GDF refrains from enforcing the guarantees granted by the Consortium, concerning the work contract settlement and acquittance. With this suspension, the GDF is prevented from performing arbitrarily any action with the intention of imposing sanctions or charges, including the enforcement of the performance bond against the Consortium, until this amparo trial is finally resolved.

However, on January 9, 2015, for the fourth time the Consortium expanded said amparo claim because on December 5, 2014, the GDF issued the Unilateral Acquittance of the Public Work Contract. Thus, through agreement of February 27, 2015, this extension was admitted for proceeding by the Judge.

As of March 2015, this amparo was in the period of evidence submittal by the Consortium.

This amparo was resolved by sentence of September 11, 2015 in favor of the Consortium, which determined essentially that the Unilateral Settlement Document must be declared without effect and that to that date the powers of the GDF to issue any settlement and / or a quittance related to the Public Work Contract 022 have expired.

Even though the amparo was resolved in favor of the Consortium, and that the sentence was not favorable in all the acts claimed, both the Consortium and the GDF filed revision recourses, which resolution is pending until the Supreme Court of Justice of the Nations issues a decision about the lack of jurisdiction controversy.

For reason of granting the amparo suspension, first the District Judge took as guarantee for said suspension the bond that the Consortium had submitted to guarantee the hidden defects that could appear in the work. However, when the duration of said bond policy expired on May 6, 2015, the District Judge requested a new guarantee, which the Consortium did not grant. So, the suspension had no longer force and effect and the GDF demanded to Ace Fianzas Monterrey (“ACE”) the bond payment.

Discontented with this request, ACE brought a nullity action before the Federal Court of Tax and Administrative Justice. The resolution of this proceeding is still pending as of the date of these financial statements.

On the other hand, the Consortium promoted an indirect amparo trial for reason of the bond claim submitted by the GDF, which resolution is still pending as of the date of these financial statements.

In the aforementioned proceedings, we consider that the decision will be favorable to the interests of the Consortium.

Acueducto II de Querétaro

By virtue of the construction of the project Acueducto II de Querétaro, various controversies emerged with the customer, Comision Estatal de Agua de Querétaro (“CEAQ”), because during the work development, there were several concepts that increased the value of the original budget. Therefore, on December 19, 2013, through Notary Public, a formal payment request was presented. However, the CEAQ did not give any reply.

In April 2014, the claim was submitted before the District Judge in Civil Matter in Querétaro for the amount of Ps.474,186.

However, the Judge declared its incapacity to rule, considering that this issue must be heard by the Judge in administrative matters; therefore, Suministro de Agua de Querétaro (“SAQSA”) filed an appeal.

F-145

The Court that heard of the appeal resolved that this is a civil, not an administrative, issue, but considered that it is the competency of a District Judge of the Federal District, based on what was agreed in one of the modifying agreements to the contract, ordering that the lawsuit and its annexes were returned to SAQSA.

In November 2014, the claim was filed again, residing in the Seventh Judge of District in Civil Matters in the Federal Districts. Therefore, in December 2014, CEAQ, BANOBRAS, and one of the two supervisory companies were summoned.

In January 2015, the CEAQ and BANOBRAS replied to the claim, opposing on the grounds of lack of jurisdiction by matter and by territory, that is, that the process must be in administrative matters and processed in the City of Querétaro.

The Court resolved that the lack of jurisdiction challenges were unfounded. Therefore the CEAQ and BANOBRAS filed an appeal. The decision was issued against them. Thus, both institutions filed an amparo action against the sentence of October 30, 2015, issued by the Third Unit Court in Civil and Administrative Matters of First Circuit, which resolved to declare that the Third Judge of District in Civil Matters in Mexico City had jurisdiction.

On April 15, 2016, the Second Unit Court in Civil and Administrative Matters of the First Circuit issued a sentence resolving not to protect the CEAQ and BANOBRAS.

CEAQ and BANOBRAS could file a revision recourse against this sentence.

SAQSA and the CEAQ have held several discussions to reach a conciliatory agreement. They are analyzing the technical concepts of the claim, the financial aspects to see how the debt could be paid, and finally, the legal aspects to conclude the legal process and execute a modifying agreement to the CPS.

Based on the evidence that SAQSA submitted in the claim, the Entity believes there is a high probability that it will recover the amounts it is owed.

Distribuidor Vial Puebla

The government of the state of Puebla, through the State Infrastructure Secretary, initiated a bid for the modernization of the interchange of the Mexico – Puebla highway and the Santa Ana – Chautempan freeway.

The original amount of the contract was of Ps.670,000; the Project was completed with a total investment of Ps.1,119,000. Therefore, there is a difference in favor of ICA of approximately Ps.450,000.

During the work execution, various factors occurred that affected the work program and scope, causing cost overruns to ICA, such as:

1. Various real estate properties required for the work execution were not cleared;

2. The executive project was modified;

3. ICA had to make extraordinary expense to release the rights of way, and

4. There was social opposition that delayed the agreed-upon program schedule.

On December 5, 2013, a formal payment request was made to the Infrastructure Secretary of the State of Puebla. However, this authority did not reply. Therefore, on August 22, 2015, the claim was submitted before the local courts of the state of Puebla for the amount of Ps.472,789.

F-146

Management considers that it has robust elements to recover the amounts described herein.

According to the legislation of the state of Puebla, before bringing a lawsuit, the defendant must be summoned on three occasions at least to see if a conciliatory agreement can be reached. Otherwise, the defendant is summoned and is granted a certain time to reply to the claim. This is what happened in this issue.

However, as the Government of Puebla did not appear in the three conciliation hearings, it was summoned and during the time given for it to reply to the claim, the file that contained the Entity’s demand was lost.

For the above reasons and due to the delays of the Court to expedite the document replacement, ICA filed several amparos to exercise pressure on the Judge and ordered the replacement, which was ultimately replaced. The government of the state of Puebla replied to the demand and as of the date of these financial statements, it is in evidence submittal stage. On April 20, 2016, the expert evidence was submitted, offered by ICA in financial engineering, costs, technical and accounting matters.

It is worth mentioning that the government of the state of Puebla did not offer any expert evidence. Therefore, the Entity considers that there are high probabilities to recover certain amounts it is owed as its expert evidence is properly supported.

The Entity estimates that the recovery process will take at least twelve months.

ICA vs Hermosa Provincia

ICA filed a claim against Constructora Hermosa Provincia, because that company has sued ICA on several occasions for civil matters to pay several benefits. The judges that have heard these claims have determined that statute of limitations on the right to sue ICA have expired.

The elements submitted to support the investigation and evidence the facts were the documents of the different civil actions that the Constructora Hermosa Provincia has filed. It was proved that the decisions established the statute of limitations as well as res judicata (a matter already judged).

The prevailing problem is that the address of this company cannot be located. Thus, the lawyer and attorney-in-fact that promote the claims have never indicated an address for service of notice and they have always indicated the courthouse at the address to be served notice.

In 2015, Constructora Hermosa Provincia filed a new civil claim, demanding the same benefits against ICA, but now for the amount of Ps.42,500, superior to the previous demands. Therefore, a claim expansion will be presented.

The Entity insist that the rights of Hermosa Provincia have expired and is res judicata. However, it is necessary to deal with the claims and follow-up on them in order to halt further legal action brought forth by this company.

The Entity has not recorded any provision relating to this claim, as it is not probable that an outflow of resources embodying economic benefits will be required to settle this obligation

ICA vs Ignacio Domínguez Parra y Simón García Huizar (Mazatlán)

ICA filed a claim against Messrs. Ignacio Dominguez Parra and Simon Garcia Huizar. These individuals were paid various compensations ordered by civil authority twenty years ago, but continue to try to obtain undue personal advantage, based on arbitrary, illegal, and inaccurate statements in several demands of guarantees, intending to obtain illegal profits for the amount of Ps.469,000.

F-147

Ignacio Dominguez Parra filed an amparo action before the Court of District for fear of being arrested when he gave his statement before the Prosecutor’s Office. The decision was not to protect him and the amparo was denied.

In parallel, his partner, Simon Garcia Huizar, gave his statement before the Public Prosecutor’s Office. He said that he has not filed any action against ICA because twenty years ago ICA paid them for their claim, which was founded at that time.

With the above statement, the Federal Prosecutor’s Office issued the order of appearance and location of Ignacio Dominguez Parra. So, this individual filed a new amparo action, which resolution is currently pending.

As of the date of these financial statements, the preliminary investigation is on hold until the above-mentioned amparo action is resolved.

It is worth mentioniong that in the amparo suit, the Supreme Court of Justice of the Nation resolved that it the case was res judicata (a matter already judged). Therefore, the Entity believes it is remote that there will be an unfavorable outcome.

Bahía Petempich

ICA filed an ordinary commercial trial against the company Desarrolladora Bahía Petempich to demand the payment of Ps.67,349, for concept of the remaining balance of the price agreed for the construction of the project called Bahía Petempich, as well as for financial expenses, additional and extraordinary works.

For reason of several procedural actions, the trial was suspended for threes year and it was not until the month of March 2015 that the process continued. As of the date of these financial statements, it is in the judgment issuance process in the first instance.

The Entity considers that the probability of recovery of the account receivable is remote and has recorded allowance for doubtful accounts.

f. ICA Infraestructura

José de Jesús Montes Lozano.

The controversy originated in a highway accident that occurred on December 24, 1999 in the Autopista de Occidente, operated by Maxipistas, S.A. de C.V. (“MAXIPISTAS”), caused by excessive speed and a tire abandoned on the highway. Two people died.

Consequently, on December 14, 2001, the successors of the deceased demanded the payment of various compensations, which were indicated only conceptually, with the intention of quantifying them in the sentence issuance. So far, the amount is unknown.

On November 10, 2008, sentence was issued in the first instance, condemning MAXIPISTAS to pay to the plaintiff the amounts for concept of indemnification for moral and psychological damage that are quantified. However, this sentence is not final because of several challenges submitted by the parties.

In January 2013, the plaintiff filed a claim to the Supreme Court of Justice of the Nation, for that the legal judgment, mentioned in the preceding paragraph, was considered final and thus executed against Maxipistas. However, the Entity considers that legal decision shall be issued in its favor, if the judgment has not been final, is because the plaintiff has challenged the resolutions of the original

F-148

Judge, mainly because it did not quantify at the appropriate procedural moment the compensation of moral damages. Thus, the Entity has not recorded any provision relating to this lawsuit, as it is not probable that an outflow of resources economic will be required to settle these obligation.

Concerning the admission of the claim submitted before the Supreme Court of Justice of the Nation, the Entity was never given notice because it has been dismissed.

In December 2013, the file was referred to the court of origin in Guadalajara, Jalisco, where it was expected that the plaintiff would declare the amount that it is seeking under the lawsuit.

This trial did not have any procedural movements during 2014.

In 2015, the plaintiff reiterated what it demanded in its initial writing, which was for an approximate indemnification amount of Ps.100,000. The Judge decided to process it, emphasizing that this award would occur according to a resolution that was not challenged by the plaintiff. Additionally, the Judge indicated that the only indemnification applicable was for lost profits, meaning that the amount to be paid must match what each of the victims would have earned in minimum wage and in accordance with the life expectancy they had when they died, reducing significantly the indemnification to an amount not to exceed Ps.3,000.

By virtue of the above, the plaintiff appealed and as of the date of the financial statements, the proceeding is suspended until this recourse is resolved. The Entity believes that there is a high probability that the resolution will be in favor of the interests of ICA.

g. Inmobiliaria Baja

Indemnification request for expropriation of plots of land in Querétaro

In writing dated November 27, 2013, Inmobiliaria Baja, S.A. de C.V. (hereinafter, Inmobiliaria Baja), requested to the Ministry of Communications and Transportation the payment of indemnifications owed for reason of the expropriation of two plots of land, one of 159,887.75 m² (larger plot of land) and another of 60,487.75 m² (smaller plot of land) located in the city of Querétaro, Querétaro.

This request was filed before the General Civil Aviation Direction (hereinafter, the DGAC); and through official document number 4.1.-372, dated April 4, 2014, it refused to admit said request by considering that the right to submit it had expired.

Inmobiliaria Baja filed an indirect amparo action against the denial of the DGAC, which was processed before the Sixteenth Court of Justice in Administrative Matters of the First Circuit, with the file number 747/2014, and it was resolved through final sentence of July 31, 2014, granting the amparo to Inmobiliaria Baja so that the DGAC leaves without effect the official document number 4.1.-372 of April 4, 2014 through which it refused to admit the request of Inmobiliaria Baja, and it deals with its request that consists of determining the indemnification derived from the expropriations.

The First Collegiate Court of Circuit of the Auxiliary Center of the First Region, located in Mexico City, confirmed the above final sentence.

In compliance with the above, the DGAC declared null and void the official document number 4.1.-372 dated April 4, 2014 and it admitted for processing the request of Inmobiliaria Baja, communicating to it that it would request to Instituto de Administracion y Avaluos de Bienes Nacionales (hereinafter, INDAABIN) to determine through an appraisal the price that it would establish as indemnification of the areas expropriated.

F-149

Through various writings of November 3 and 4, 2015, Inmobiliaria Baja requested to the DGAC to be given notice of the appraisals that the INDAABIN issued to determine the indemnification price, but no reply was obtained.

In disagreement with the above, Inmobiliaria Baja filed an indirect amparo action against the omission and delay of the DGAC to give notice of the appraisals and to resolve the proceeding concerning the payment of the indemnifications owed, which is processed before the Sixteenth Court of District in Administrative Matters of the First Circuit with the file number 2093/2015.

For reason of this amparo trial, the DGAC submitted the appraisals and Inmobiliaria Baja had knowledge of them, and has expanded its initial claim document to demand only the appraisal made to the larger plot of land, because the amount determined as indemnification payment for it is derived from an appraisal updating that has expired.

In January 2014, Inmobiliaria Baja requested the appraisal of the plots of land, resulting in the following:

• Larger plot of land Ps.271,193 and

• Smaller plot of land Ps.102,594

The INDAABIN issued the following appraisal:

• Larger plot of land Ps.279 and

• Smaller plot of land Ps.210,093

The Entity considers that the INDAABIN must correct the appraisal amount of the larger plot of land, because it is illogical that the smaller plot of land has a superior value. The Entity considers that the probability of recovery of the superior values is high.

h. ICA Internacional

Instituto de Desarrollo Urbano del Distrito Capital de Bogotá, Colombia (“IDU”)

In April 2002, ICA was condemned by an arbitration court to pay to the IDU an indemnification for default in a work contract of the project “Mall Vial” in Bogotá, for approximately US$2,200,000, and established the criteria for the contract acquittance. This decision was acknowledged by the Mexican judicial authority in January 2009 and the resulting amount was paid.

In another proceeding related to the same project, the IDU filed a lawsuit against ICA before a court of Colombia for damages and contract default, for an approximate amount of US$4,720,000, and filed a claim against the bonding company for the return of the advance payment that had not been amortized.

On the other hand, ICA filed a counterclaim demanding an indemnification plus damages and losses for the amount of US$17,800,000. The Court ordered the suspension of all the actions against the bonding company until the resolution of the counterclaim filed by ICA.

In June 2011, the suspension of the process ordered by the Judge in the executive proceeding, filed against the bonding company, was completed, updating the possibility that despite the mutual claims of the parties, the bond enforcement could be requested for the amount of US$17,000,000 plus interest, even though there are legal recourses to challenge this type of determination.

On September 26, 2012, a conciliation settlement was executed between the parties, with the intention to put an end to all the controversies derived from the execution of the contract 462 of 1997. This agreement was submitted before the Administrative Court of Cundinamarca, which to make a determination, it requested the Attorney General’s Office of the Nation of Colombia to provide its opinion to this regard.

F-150

On February 28, 2013, the Administrative Court of Cundinamarca denied the conciliation with the IDU. Therefore, on March 8, 2013, ICA filed an appeal recourse, which was resolved through sentence of April 17, 2013. In this sentence, the partial suspensive effect was granted against the decree in which the conciliation proposal was partially accepted and the file was sent to the Council of State for its resolution.

With regards to the executive process started by the IDU against Chubb de Colombia de Seguros S.A. and ICA, for the collection of the resolution that declared the contract expiration and enforced the pecuniary criminal clause (proceeding No. 2002-02258), the Court issued sentence on October 18, 2013, in which it did not give a statement about the exceptions presented by ICA, and ordered to continue with the enforcement. Against this decision an appeal recourse was filed on November 28, 2103, based mainly on the conciliation agreed with the IDU. Through decree of April 28, 2014, the Council of State admitted the waiver, thus putting an end to this proceeding.

Concerning the executive process started by the IDU against Chubb de Colombia de Seguros S.A. e ICA, for the collection of the resolution that enforced the amparo of down payment of the performance guarantee (proceeding no. 2003-00429), the Administrative Court of Cundinamarca stated that there was no evidence for the exceptions proposed by Chubb de Colombia de Seguros S.A. Therefore, it ordered to continue with the enforcement of the amount indicated in the claim presented on February 18, 2003. Against this decree, on May 3, 2013, an appeal recourse was submitted and a nullity request.

Through resolution of October 24, 2013, the Council of State approved the conciliation agreed with the IDU. Therefore, the parties consider that the contract 462 of 1997 has been acquitted. As a result of the above, ICA made the payment of the sums involved in the conciliation, and the IDU presented its respective waiver in the executive proceeding no. 2002-2258, which was accepted through a decree of the Council of State, notified on May 6, 2014.

On May 14, 2014, the IDU presented the corresponding waiver to the proceeding no. 2003-00429, which had a negative resolution through decree of August 4, 2014 because the IDU representative did not have the express power to withdraw from the proceeding.

On August 14, 2014, the IDU lawyer filed an appeal for reversal, accompanied by a new power of attorney, through which the IDU authorized the express withdraw from the proceeding. From August 28, 2014, the proceeding is with the Residing Judge for the recourse resolution.

Through decree of February 12, 2015, it was partially resolved favorably, because the Residing Judge only accepted the waiver about the IDU, arguing this time that the plaintiffs are two different entities; the IDU and the Capital District – Ministry of Public Works, and that the request was submitted only by the representative of the IDU. Against this decision, the representative of the IDU presented on February 20, 2015 an appeal for reversal, which was rejected at it was found unfounded through decree of April 29, 2015, in which the Council of State also ordered to continue with the proceeding.

Through decree of August 20, 2015, the Council of State decided to admit the appeal recourse presented by Chubb, against the judgment in the first instance, issued by the Administrative Court of Cundinamarca on April 12, 2013.

In continuation with the proceeding, through decree of September 16, 2015, the Council of State gave notice to the parties so that they presented their conclusion allegations, but against that decision, the IDU also filed an appeal for reversal. Since October 29, 2015 to this date, the process has been with the Residing Judge for its study and resolution.

F-151

Direct repair process started by the Corporacion Autonoma Regional de la Frontera Nororiental (“CORPONOR”) against the Consortium ICAMEX – TERMOTÉCNICA

On September 28, 2012, the CORPONOR gave notice to the Consortium ICAMEX – TERMOTÉCNICA of the out-of-court conciliation request in which this Consortium is assigned, as well as the Empresa Colombiana de Petroleos ECOPETROL, S.A., the direct repair for environmental damages as a result of the hydrocarbon spill that occurred in the oil duct Caño Limon – Coveñas.

The sum anticipated by CORPONOR to recover the ecosystem and leave it in the condition it was before the spill amounts to approximately US $18,510,000.

CORPONOR communicated to the parties involved that an out-of-court conciliation hearing would be held on November 7, 2012. In this hearing, an agreement was not reached. Therefore, CORPONOR could proceed to file a demand against the Consortium ICAMEX – TERMOTÉCNICA.

As a result of the above, on December 9, 2013, CORPONOR filed before the Administrative Court of Norte de Santander the demand of direct repair against Ecopetrol and the Consortium ICAMEX – TERMOTÉCNICA, which was admitted through decree of March 5, 2014.

On April 28, 2015, the initial hearing of the proceeding was held, with the opportunity to defend the exceptions stated in the reply to the lawsuit, but they were denied by the Judge. Against this determination, ICAMEX- TERMOTÉCNICA filed an appeal recourse, which was resolved unfavorably on July 21, 2015 by the Council of State, considering that they must be resolved in the final judgment.

The file was returned to the Administrative Court of Norte de Santander to continue with the proceeding. Through decree of October 5, 2015, the parties were called so that on January 26, 2016 the Initial Hearing continues.

Notwithstanding the above, it is not considered that is necessary to create a reserve to deal with this process, as there is no legal indicator currently in the trial about a potential contingency. Even though the trials started in 2012, the court has had delays and it is during the evidence stage that the legal proceeding has been delayed. Additionally and based on the information available, including the review of the contract between the consortium and ECOPETROL, the belief is that there is a valid defense that the hydrocarbon spill is not attributable to the Consortium ICAMEX – TERMOTECNICA, and that the demands of the government are outside the contract scope.

According to what mentioned in the previous paragraph, The Entity has not recorded any provision relating to this lawsuit, as it is not probable that an outflow of resources economic will be required to settle these obligations.

Lawsuit against ICA Panamá, S.A. for the rights of way of the Corredor Sur

Banco Hipotecario Nacional (“BHN”) filed and ordinary proceeding of a higher amount against ICA Panamá, S.A. for the effects caused by the use of rights of way of the Corredor Sur, which was admitted by the Third Court or Circuit on December 11 2003. In it, it is demanding the payment of the amount of US$2,568,000. Once the lawsuit was admitted, a difficult process has developed in terms of formal aspects, which have been resolved throughout the trial. Evidence submittal has been was set up for the month of February 2012.

In March 2012, the expert reports were presented, both of the experts of the Court and of the ENA (formerly ICA PANAMÁ) and BHN. The appraisal results show figures superior to the estimated amount, for the issue of indemnification of the property affected during the construction of the Corredor sur. The professional fees of the Court expert were rejected and submitted to review because they were considered to be excessive.

F-152

In March 2013, the Court issued a sentence in the first instance, acknowledging the pretense of BHN, establishing as compensation the sum of US $1,981,598. On March 5 and 19, BHN and the defendant, respectively, filed an appeal recourse against the sentence, which is pending of resolution.

On June 5, 2013, notice was given to the Specialized District Attorney’s Office in Civil Matters of the sentence, and on June 10, it requested its clarification and filed an appeal recourse against it. Through decree no. 1656/456, dated October 31, 2013, the Court did not admit the clarification request. Through decree no. 1877/456 dated December 13, 2013, the appeal recourses filed by the parties were admitted against the sentence in the first instance no. 12/456-03. The recourses are pending of resolution.

Lawsuit of higher amount through an ordinary proceeding filed by Sonama Panamá, S.A. and Sonama, S.A., against the Consortium ICA-FCC-MECO

On June 28, 2013, Sonama Panamá, S.A. and Sonama, S.A., filed a lawsuit for damages and losses against the members that make up the Consortium ICA-FCC-MECO, for the amount of $25,414,183 balboas. The intentions of the plaintiffs are based on a presumed default of commercial and business obligations of the offer made to the members of the Consortium ICA- FCC-MECO, for the execution of works as subcontractor in the Project Pac-4.

The lawsuit filed was admitted through decree no. 1075, dated August 14, 2013, and it was until February 7, 2014, when ICA acknowledged its receipt. On March 21, 2014, the lawsuit was replied to before the Seventh Court of Circuit of Civil Matters of the First Judicial Circuit of Panama.

On April 25 and Jay 6, 2014, ICA, FCC, and MECO presented a document of evidence, counterevidence, and objection to them, which were developed until April 15, 2015.

When the above was completed, the conclusion defense statements were submitted.

On September 24, 2015, the Seventh Court of Civil Circuit issued the sentence no. 34, which was favorable to the Consortium, ordering only the return of the amount that the Consortium had withheld from the Companies Sonama and Sonama Panama, as well as the interest generated on it, for the amount of US $439,555.

Both parties filed an appeal recourse, which is pending of admission and referral to the Superior Court.

The main argument of the Consortium ICA-FCC-MECO to support its defense lies on the fact that the parties never executed a contract that supports the pretenses of the plaintiffs. Therefore, the Entity does not believe that it is reasonably posible that it will be required to make payment and thus has not created a reserve for this contingency.

ICA FLUOR – Dominican Republic Combined Cycle, L.L.C.

Dominican Republic Combined Cycle, L.L.C. is a subsidiary of ICATECH, with minority investment of Fluor Corporation, through which a combined cycle thermoelectric plant was built for the customer AES.

F-153

Derived from that project, the company Proyectos de Ingenieria Electromecanica, S.A., filed a civil trial against Dominican Republic Combined Cycle, L.L.C., for concept of repair of moral damages and losses, payment of cost overruns, payment of two estimates, and return of the guarantee fund.

Due to the procedural irregularities of the plaintiff, the trial continues in the first instance and is processed in the Third Room of the Civil and Commercial Chamber of the Court of First Instance of Santo Domingo, Dominican Republic. The Entity expects that a sentence will be issued in 2016, which could be challenged by the parties.

As the consideration is that the resolution in this trial will be favorable to ICA Fluor, no reserve has been created. To this date, the total value of the contingency is of approximately US $16,500,000.

i. Airports

I. Property tax

Reynosa Airport

As of December 31, 2015, the airport has in charge the following court trials pending of resolution:

In February 2011, November 2011, August 2012 and March 2014, the municipality of Reynosa filed property tax claims against the Company for Ps. 117,654, Ps. 127,312, Ps. 1,119 and Ps. 1,361, respectively. In response to these claims, the Company has filed administrative appeals before the Administrative Court (Tribunal de lo Contencioso Administrativo del Estado de Tamaulipas).

On July 16, 2015, the Administrative Court issued a ruling in the Entity’s favor declaring the annulment of the tax claim requested in February, 2011, for the amount of Ps. 117,654. As of April 27, 2016, the rest of the Company’s appeals were still pending.

The Entity does not believe that liabilities related to any of these claims or proceedings against the Entity are likely to have, individually or in the aggregate, a material adverse effect on its consolidated financial condition or results of operations. Should a court determine that these taxes must be paid in response to any future proceedings, the Entity believes that only the owners of the land would be responsible for paying these taxes directly, and the obligation to pay these taxes is not otherwise contemplated in the terms of its concessions. The Mexican government has not acknowledged an obligation to pay such taxes, however, and changes to the Mexican Constitution and other applicable laws could render the Entity liable to municipalities for property taxes in the future.

II. Amparo trial related to the requirement of municipal licenses

1. Monterrey Airport

On November 19, 2013, the Apodaca municipality executed an inspection order and closed the commercial premises located in the Monterrey airport, which include a strip mall, gas station and industrial park, because they did not have multiple licenses for ground use and/or construction. A constitutional claim lawsuit was filed against these acts challenging this shutdown and the constitutionality of the municipal order.

The court granted a provisional suspension ordering that municipa authorities remove the barriers and enable the businesses to continue operations. On October 14, 2014, the District Court ruled in favor of the Monterrey airport. On November 19, 2014, the Apodaca municipality filed an appeal before the Federal Circuit Court against the judgment.

On February 4, 2015, the Apodaca municipality filed an appeal with the Federal Circuit Court to exercise its competence to hear and determine the appeal against the October 14, 2014 judgment of the District Court. On March 6, 2015, the First Chamber of the Mexican Supreme Court decided to consider exercising its competence to hear the appeal. As of April 27, 2016, neither the Federal Circuit Court nor the Mexican Supreme Court has resolved the appeals.

F-154

Moreover, in February 2014, the Apodaca municipality filed a constitutional controversy lawsuit against the federal government for its approval of the Monterrey airport’s 2011 2015 master development program as well as the authorization of the construction projects, including the hotel at Terminal B, protected under amparo. The Mexican Supreme Court agreed to hear the constitutional controversy claim but denied the Apodaca municipality’s petition for the suspension of the challenged authorizations. However, this challenge was decided against the Apodaca municipality denying their petition to suspend the construction projects carried out at the Monterrey airport under the master development program.

On February 18, 2015, the constitutional controversy claim was decided against the Apodaca municipality. The judgment determined that the constitutional controversy claim was unfounded and declared the federal government’s authorizations to be valid.

2. Reynosa airport

In October 2014, the municipality of Reynosa issued an inspection order and imposed a stoppage on the sales of alcoholic beverages in commercial premises located at the Reynosa airport as it had not obtained a state license for the sale of alcoholic beverages.

The airport filed a constitutional claim lawsuit against these acts to challenge the closure and the constitutionality of the municipal regulations and state law. On June 9, 2015, the Federal District Court granted relief to the airport and instructed the authorities to annul the municipal acts for lack of capacity to regulate the airport inasmuch as the airport is an exclusively federal facility subject to the federal laws. The municipality of Reynosa filed an appeal with the Federal Circuit Court against the judgment, which as of April 27, 2016 has not been resolved.

The Entity has not recorded a provision relating to this lawsuit considering that the municipal requirements that are being challenged do not have an economic impact and that there are legal precedents in connection with similar cases that are favorable to its case.

III. Conflict related with ownership of certain lands

1. Reynosa airport

The Entity filed a proceeding for annulment against the Mexican Bureau of Civil Aviation and the Ministry of Communications and Transportation with the Administrative Court (Tribunal de lo Contencioso Administrativo del Estado de Tamaulipas) in relation to the administrative ruling containing a constructive disapproval of the application filed by the plaintiff with the Ministry of Communications and Transportation for the return of land of 200,000 hectares (772 square miles). The plaintiff claims that this land is situated within Reynosa airport. The Reynosa airport has been summoned in its capacity as an interested third party.

The main claim focuses on: (i) the annulment of the administrative act that deprived the plaintiff of its ownership of the real property; (ii) the restitution of the ownership rights of which it was deprived due to an irregular administrative act; (iii) the immediate return of its ownership of the real property; and (iv) the payment of damages. These claims are based on the argument submitted by the plaintiff to the effect that the disputed land is not subject to an expropriation decree.

The submission of expert evidence by the plaintiff is currently pending.

Given that the federal government is the main defendant in this case, if an unfavorable verdict is issued, it will be liable for paying the resulting economic effect, as detailed in the concession title. As of April 27, 2016, the final resolution of this dispute remains pending.

F-155

In connection with the previous judgment, on November 17, 2015 the Reynosa airport was notified of a constitutional claim lawsuit filed by another plaintiff claiming the dispossession of land of 19,603 square meters (211,004 square feet) situated within the Reynosa airport. The lawsuit was filed against the Ministry of Communications and Transportation, and the Reynosa airport was summoned in its capacity as an interested third party.

The elements of the claim are: (i) the annulment of the administrative act that deprived the plaintiff of its ownership of the real property; (ii) the restitution of the ownership rights of which it was deprived due to an irregular administrative act; (iii) the immediate return of its ownership of the real property; and (iv) the payment of damages. The Ministry of Communications and Transportation appeared at the trial and argued the inadmissibility of the claim, further arguing that the land was lawfully expropriated and that its legitimate owners were duly indemnified pursuant to applicable law. As of April 27, 2016, the final resolution of this dispute remains pending.

The Entity has not recorded any provision relating to this lawsuit, as it is not probable that an outflow of resources economic will be required to settle these obligations.

2. Ciudad Juarez airport

Parties purporting to be former owners of land comprising a portion of the Ciudad Juárez airport initiated legal proceedings against the airport to reclaim the land, alleging that it was improperly transferred to the Mexican government. As an alternative to recovery of this land, the claimants also sought monetary damages of U.S.$120.0 million. On May 18, 2005, a Mexican court ordered the Company to return the disputed land to the plaintiffs. However, that decision and three subsequent constitutional claims permitted the ruling to be reconsidered, and as a result of such constitutional claims, the original claimants must now include the Ministry of Communications and Transportation as a party to the litigation, as the Ministry of Communications and Transportation is the grantor of the concession title to the Ciudad Juárez airport. On August 28, 2009, the federal government filed its answer to the claim, in which it requested that the trial beremoved to federal court. In May 2010, the Court of Appeals granted the federal government’s request, giving the Federal Courts jurisdiction to hear the lawsuit. The plaintiffs filed a constitutional claim against this ruling before the Federal District Court in Chihuahua and on November 29, 2010, the District Court in Chihuahua confirmed the Court of Appeals ruling. Against this ruling, the plaintiffs filed an appeal (recurso de revisión) before the Federal District Circuit Court and on July 7, 2011, the Federal District Circuit Court ruled that the plaintiffs’ constitutional claim should be heard by a District Court in Ciudad Juárez. In October 2011, the District Court in Ciudad Juárez denied the plaintiffs’ constitutional claim, against which, in November 2011, the plaintiffs filed a new appeal (recurso de revisión) before the Federal District Circuit Court. On January 7, 2012, the Federal District Circuit Court confirmed that the District Court in Ciudad Juárez had jurisdiction to hear the claim. On April 30, 2012, the Federal District Court in Ciudad Juárez ruled that it did not have jurisdiction to hear the claim, and the determination of jurisdiction was sent to the Mexican Supreme Court. However, after the Federal District Court denied jurisdiction, a conflict arose that has been resolved by the Circuit Court. The Federal District Circuit Court ruled on January 13, 2013 that a state or local court must hear the lawsuit rather than a federal court. The lawsuit is still underway at this time. As of April 27, 2016, the final resolution of this dispute remains pending.

In the event that any subsequent action results in a decision substantially similar to the May 18, 2005 court order or that is otherwise adverse to the Entity, and the Mexican government does not subsequently exercise its power of eminent domain to retake possession of the land for its use, which the Entity believes the terms of its concessions would require, its concession to operate the Ciudad Juárez airport would terminate. In 2015, the Ciudad Juárez airport represented 4.1% of the Entity’s consolidated total revenues. Although the Entity believes and have been advised by the Ministry of Communications and Transportation that under the terms of its concessions the termination of the Ciudad Juárez concession would not affect the validity of its remaining airport concessions and that the Mexican government would be

F-156

obligated to indemnify the Entity against any monetary or other damages resulting from the termination of its Ciudad Juárez concession or a definitive resolution of the matter in favor of the plaintiffs, the Entity may not be so indemnified.

The Entity has not recorded any provision relating to this lawsuit, as it is not probable that an outflow of resources economic will be required to settle these obligations.

IV. Conflict related to the purchase-sale of land

Monterrey airport

On January 12, 2012, a third party filed a claim that it was the owner of a property previously acquired by the Monterrey airport. The third party is seeking a declaration that the documents of sale to the Monterrey airport are null and void based on the absence of a sale deed for the property and the restitution of the property to the third party, together with the corresponding improvements and property rights.

On August 27, 2015, a new claim was filed against the Monterrey airport in connection with the ownership of land with an approximate area of 96 hectares (107,639 square feet) acquired in 2008. The claim was filed by Banco Mercantil del Norte, S.A., acting as trustee of a transnational domain trust, arguing that the trust’s settlors are the rightful owners of the property. The claim was filed against the Monterrey airport but it was requested to call to trial the seller of the property as interested third party. As of April 27, 2016, the final resolution of this dispute remains pending.

The contingency is not quantified in the demand. However, the Entity considers that if an unfavorable verdict is issued, the economic impact of the trial would be assumed by the seller of the land. The Entity has not recorded any provision relating to this lawsuit, as it is not probable that an outflow of resources economic will be required to settle these obligations.

V. Other trials

Acapulco airport

In December 2011, the Local Tax Audit Administration of the Tax Administration Service in Acapulco conducted a new audit of the Acapulco airport and determined a tax liability of Ps.27,876 for the year of 2006 for alleged profit sharing omissions, excess deductions, surcharges and fines. The Entity filed a motion for reconsideration against such determination; the resolution for the motion resulted in a new unpaid income tax liability and additional government charges of Ps.15,946 as well as profit-sharing of Ps.2,787. The Entity believes that it has sufficient elements to obtain a favorable result; otherwise, it intends to file an administrative appeal with the Federal Tax and Administrative Court of Justice.

In opposition to this final judgment, a claim was brought before the Federal Tax and Administrative Court of Justice, which was also decided, on June 17, 2014, in the Entity’s favor. Pursuant to the decision, the Tax Administration Service (Servicio de Administración Tributaria) determined a new tax credit amounting to Ps.11,864. The credit was announced on December 9, 2014 and challenged before the Federal Tax and Administrative Court of Justice. As of April 27, 2016, the final resolution of this dispute remains pending. The Entity has not recorded any provision relating to this lawsuit, as it is not probable that an outflow of resources economic will be required to settle these obligations.

j. Performance guarantees - In the ordinary course of business, the Entity is required to secure construction obligations, mainly related to the completion of construction contracts or the quality of its work, by granting letters of credit or bonds. At December 31, 2015, the Entity had granted bonds to its customers for Ps.16,544 million of Mexican pesos, U.S.$194 million, $226 Quetzales and $135,614 Colombian pesos. At December 31, 2015, the Entity had granted bonds to its customers for Ps.16,515 million of Mexican pesos y U.S.$172 million, whose responsibility is for the same amount.

F-157

Additionally, the Entity has issued letters of credit to guarantee its performance obligations under certain concession arrangements and construction contracts, in the amount of U.S$5 million, EUR$1 million and Ps.3,171 million of Mexican pesos.

k. Guarantees – The Entity has granted guarantees for the amount of US $459 million, equivalent to $7.952 billion pesos, to some of its related parties for bank liabilities contracted for them, of which $1.350 billion pesos are related to short-term loans (see note 21) and $6.582 billion pesos are related to long-term loans (see note 27).

Based on the nature of its activities, ICA is exposed to different financial risks, mainly as a result of its ordinary business activities and its debt contracts entered into to finance its operating activities.

The Corporate Treasury function provides services to ICA business to coordinate access to domestic and international financial markets, monitors and manages the financial risks relating to the operations of ICA. The principal financial risks to which operating units are exposed are: market risk (interest rates, currency exchange rates and foreign currency pricing), credit risk and liquidity risk.

Periodically, the Entity’s management assesses risk exposure and reviews the alternatives for managing those risks, seeking to minimize the effects of these risks using financial derivatives to hedge risk exposures. The Board of Directors sets and monitors policies and procedures to enter into derivative financial instruments. The Entity does not use derivatives for speculative purposes. The risks, to which the Entity is exposed, are described below.

c. Market risk

The Entity is exposed to price risks, mainly for the following activities:

Construction contracts

The construction contracts, into which the Entity enters, are generally either: (i) fixed price (either “lump sum” or “or not-to exceed”) or (ii) profit margin over cost (“unit price”). The evaluation of the risks related to inflation, exchange rates and price increases for each type of contract depends on if the contract is a public works contract or if it is with the private sector, which is normally different.

In unit price contracts in the private sector, the customer generally assumes the risks of inflation, exchange-rate and price increases for the materials used in the contracts. Under a unit price contract, once the contract is signed, the parties agree upon the price for each unit of work. However, unit price contracts normally include escalation clauses whereby the Entity retains the right to increase the unit price of such inputs as a result of inflation, exchange-rate variations or price increases for the materials, if any of these risks increases beyond a percentage specified in the contract.

For unit price contracts related to public works, in addition to escalation clauses, in Mexico the “Public Works and Services Law” establishes mechanisms to adjust the value of such public unit-price contracts for cost increases. The Public Works and Services Law provides the following mechanisms for the adjustment of unit prices in unit-price contracts: (i) a review of individual unit prices for which adjustment may be possible; (ii) a review of unit prices by group, which multiplied by their corresponding amounts of work remaining to be performed, represent at least 80% of the total amount of remaining work under the contract, and (iii) for those projects in which the relationship between the input and the total contract cost is established, an adjustment to reflect the increased cost may be made based on such proportion. The application of these mechanisms is required to be specified in the relevant contract.

F-159

In lump sum contracts, not-to-exceed contracts or contracts where there are no escalation clauses in which the Entity undertakes to provide materials or services at fixed unit prices required for a project in the private sector, generally the Entity absorbs the risk related to inflation, exchange-rate fluctuations or price increases for materials The Entity mitigates these risks as follows: (i) when the bid tender is prepared, such risks are included in determining the costs of the project based on the application of certain economic variables which are provided by recognized economic analysis firms; (ii) contractual arrangements are made with the principal suppliers, among which advance payments are made to ensure that the cost of the materials remains the same during the contract term; and, (iii) the exchange-rate risk is mitigated by contracting suppliers and subcontractors in the same currency as that in which the contract is executed with the customer. For those risks that cannot be mitigated or which surpass acceptable levels, the Entity carries out a quantitative analysis in which it determines the probability of occurrence of the risk, measures the potential financial impact, and adjusts the fixed price of the contract to an appropriate level.

For fixed price contracts in the public sector, the Public Works and Services Law protects the contractors when adverse economic conditions arise that could not have been anticipated at the time of awarding the contract and thus were not considered in the initial contract bid. The Public Works and Services Law allows the Controller’s Office (Secretaria de la Función Pública) to issue guidelines through which public works contractors may recognize increases in their initial contract prices as a result of adverse economic changes. The proposed application of these mechanisms for the public-to-private initiative is uncertain, but the proposed law would benefit the Public/Private Partnership (Proyecto para Prestación de Servicios, or PPS) by introducing options to renegotiate, in good faith, the contract terms in the event of government action to increase the project costs or otherwise reduce contractual benefits to developers.

In recent years, the construction contracts have been increasingly of the fixed price type or mixed price contracts in which a portion of the contract is at fixed price and the rest at unit prices. Even though the Entity has entered into contracts with unit pricing in the last 3 years, it believes that fixed price contracts are more prevalent in the construction market and the contracts that the Entity enters into in the future will reflect this shift to fixed price contracts.

Additionally, it is expected that due to trends toward financing, future contracts related to concessions, infrastructure construction and industrial construction will restrict price adjustments for additional work performed due to incorrect specifications in the original contract.

Concessions

The financing structure of the concession segment naturally exposes the Entity to interest rate risk. The Entity manages a fixed rate in order to limit the impact of the fluctuations in interest rates and optimize the cost of debt. To minimize the effects of this risk, the Entity uses interest rate swaps. These swaps are classified as cash flow hedges.

The Entity is exposed to price risk in concessions, particularly in projects in which the construction risks are assumed; the overruns can generate a higher investment in capital than expected which results in a lower return on capital. Generally, the concession contracts and PPS stipulate that the grantor must deliver the right-of way to the land involved in the project in accordance with the construction program. If the grantor does not timely release such rights of way, the Entity might be required to incur additional investments and suffer delays at the start of operations and could therefore find it necessary to seek amendments to the concession contract or PPS. ICA cannot ensure that it will reach agreement on the amendments to any of such contracts. Particularly in relation to new projects, in which it absorbs construction costs, cost overruns may generate a higher base investment than that expected, which results in a lower return on investment. Based on these factors, there is no assurance that its return on any investment in a highway, bridge, tunnel or residual water treatment plant concession matches the estimates established in the respective concession contract or PPS.

F-160

The return to the Entity on any investment in a concession for a highway, bridge, tunnel or wastewater treatment plant is based on the duration of the concession and the amount of capital invested, as well as the amount of the revenues obtained from use, debt servicing costs and other factors. For example, traffic volumes and, consequently, the revenues from highway tolls, are affected by several factors, including toll rates, the quality and proximity of alternate free highways, the price of fuel, taxes, environmental regulations, the purchasing power of the consumer and general economic conditions. The traffic volume of a highway is also strongly influenced by its integration into other highway networks.

Payments of receivables under financial assets from concessions are indexed to inflation as permitted by the concession contracts, by reference to the INPC, thereby allowing a natural hedge of the liability in UDIs entered into related to those concessions.

Interest rate risk management – This risk principally arises from changes in the future cash flows of debt entered into variable interest rates (or with short-term maturity and presumable renewal) as a result of fluctuations in the market interest rates. The purpose of managing this risk is to lessen the impact in the cost of the debt due to fluctuations in such interest rates. To mitigate this risk, ICA enters into financial derivatives which ensure fixed interest rates, establish maximum limits (ceilings) or narrow fluctuation bands for interest payments, relative to a substantial portion of any debt affected by such risk.

The risk is also managed by ICA through maintaining an appropriate combination of fixed rate loans and variable rate loans, and using hedging and futures contracts for interest rates. Hedging activities are assessed regularly so that they are in line with the interest rates and the identified risk so as to ensure that the most profitable hedging strategies are applied.

As of December 31, 2015, the Entity had an approximate of Ps.69,307 million of outstanding debt, before commissions and issuance costs, of which 81% had a fixed interest rate and 19% a variable interest rate. As of December 31, 2014, the Entity had an approximate of Ps.69,999,241 million of outstanding debt, of which 79% had a fixed interest rate and 21% a variable interest rate. As of December 31, 2013, the Entity had an approximate of Ps.49,373 million of outstanding debt, of which 62% had a fixed interest rate and 38% a variable interest rate. The interest rate on the variable rate debt of ICA is generally based on reference to the LIBOR rate and the TIIE rate.

ICA has entered into cash flow hedge contracts, including cash flows in foreign currency and other commercial derivative instruments for the duration of some of its long-term lines of credit, in order to reduce uncertainty due to interest rate fluctuations.

Analysis of interest-rate sensitivity – The following sensitivity analyses are based on the assumption of an adverse change in basis points, in the amounts indicated, applicable to each category of variable rate financial liability. The sensitivity analysis below has been determined based on the exposure to interest rates for both derivatives and non-derivative instruments at the end of the reporting period. For liabilities accruing interest at a floating rate, the analysis was prepared assuming the amount of liability outstanding at the end of the year was outstanding throughout the year. ICA determines its sensitivity analyses by applying the hypothetical interest rate to its outstanding debt and making adjustments due to such fluctuations for the debt which is hedged by the financial derivatives.

For the year ended December 31, 2015, a hypothetical, instantaneous and adverse change of 100, 50 and 25 basis points in the interest rate applicable to the variable rate financial liabilities, including financial derivatives only if they are held for hedging purposes, would have resulted in an additional financing expense of approximately Ps.179 million, Ps.95 million and Ps.54 million, respectively.For the year ended December 31, 2014, a hypothetical, instantaneous and adverse change of 100, 50 and 25 basis points in the interest rate applicable to the variable rate financial liabilities, including financial derivatives only if they are held for hedging purposes, would have resulted in an additional financing expense of approximately Ps.34 million, Ps.13 million and Ps.5 million, respectively. For the year ended December 31, 2013 a hypothetical, instantaneous and adverse change of 100, 50 and 25 basis points in the interest rate applicable to the variable rate financial liabilities, including financial derivatives only if they are held for hedging purposes, would have resulted in an additional financing expense of approximately Ps.169 million, Ps.87 million and Ps.43, million, respectively.

F-161

Foreign exchange risk management – The Entity performs transactions denominated in foreign currency; consequently, it is exposed to exchange rate risks, which are managed within the parameters of established and approved policies by using, as the case may be, exchange rate forward contracts when they are considered effective. The main risk related to the exchange rate involves changes in the value of the Mexican peso against the U.S. dollar.

In fixed price, lump sum or guaranteed maximum price contracts, the Entity assumes the risk of fluctuations in the exchange rate between the Mexican peso and other currencies in which the contracts are expressed, included the related financing agreements, or other contracts entered into for the purchase of supplies, machinery or raw materials, ordinary expenses and other inputs. A severe devaluation or appreciation of the Mexican peso could also result in an interruption in the international currency markets and could limit the ability to transfer or convert pesos to U.S. dollars and other currencies in order to make timely payments of interest and principal on the related obligations expressed in U.S. dollars or in other currencies. Although the Mexican government does not currently restrict, and has not restricted since 1982, the right or ability of Mexican individuals or business entities to convert pesos into U.S. dollars or other currencies, or to transfer them outside Mexico, the Mexican government could institute exchange control policies in the future. It cannot be guaranteed that the Banco de Mexico will maintain its current policy regarding the peso. The fluctuation of the currency may have an adverse effect on the Entity’s financial position, results of operations and cash flows in future years.

For the year ended December 31, 2015, approximately 33% of consolidated revenues were expressed in foreign currencies, mainly U.S. dollars. An appreciation of the Mexican peso against the U.S. dollar would reduce the dollar-denominated revenues and the Entity’s obligations under dollar-denominated debt when expressed in pesos, whereas a depreciation of the peso against the U.S. dollar would increase the Entity’s dollar-denominated revenues and obligations under debt agreements when expressed in pesos.

For the year ended December 31, 2015, 2014 and 2013, approximately 16%, 22% and 26%, respectively, of the Entity’s backlog was denominated in foreign currencies, and approximately 15%, 23% and 22%, respectively, of the accounts receivable were denominated in foreign currencies. For the year ended December 31, 2015, 2014 and 2013, approximately 12%, 15% and 16%, respectively, of consolidated financial assets were denominated in foreign currencies and the rest in Mexican pesos. Furthermore, for the year ended December 31, 2015, 2014 and 2013, approximately 44%, 44% and 43%, respectively, of debt was expressed in foreign currencies A depreciation of the Mexican peso against the U.S. dollar would increase the peso value of the costs and expenses denominated in foreign currency and, unless they were denominated in the same currency as the source of payment (as established by ICA’s risk management policies), it would increase the obligations for debt expressed in foreign currency. For the year ended December 31, 2015, the Mexican peso depreciated against the U.S. dollar by 18%, related to the foreign exchange rate existing of the year ended December 31, 2014. For the year ended December 31, 2014, the Mexican peso depreciated against the U.S. dollar by 13%, related to the foreign exchange rate existing of the year ended December 31, 2013. For the year ended December 31, 2013, the Mexican peso depreciated against the U.S. dollar by 1.75%, related to the foreign exchange rate existing of the year ended December 31, 2012.

Foreign currency sensitivity analysis – The following sensitivity analyses are based on an instantaneous and unfavorable change in exchange rates which affect the foreign currencies in which the assets and liabilities are expressed. These sensitivity analyses cover all the assets and liabilities denominated in foreign currency, as well as its derivative financial instruments. Sensitivity is determined by applying a hypothetical exchange rate change to those items, including the outstanding debt expressed in foreign currency, subsequently adjusting for this fluctuation for debt hedged by derivative financial instruments.

As of December 31, 2015, 2014 and 2013, a hypothetical, instantaneous, unfavorable change of 100 cents to the exchange rate applicable to the Entity’s receivables, payables and debt, including derivative financial instruments not held for trading purposes (and excluding the debt hedged by instruments held for trading purposes), would have resulted in an estimated exchange loss of approximately Ps.1,884, Ps.1,977 and Ps. 1,273 million, based on the highest value in pesos of the debt expressed in foreign currency. As of December 31, 2015, the Entity did not hold any derivative financial instruments for trading purposes, except as mentioned in Note 26.

F-162

UDI exchange rate risk management – For the years ended December 31, 2015, 2014 and 2013, 17%, 19% and 17%, respectively, of the Entity’s debt is denominated in UDIs, which corresponds to the ICASAN, LIPSA, Mayab, Sarre and Papagos debt is denominated in UDIs. Although a portion of long-term debt is contracted in UDIs, the Entity does not believe a significant exchange risk exists, because the issuance of the debt at Sarre and Papagos was under the same currency in which the Entity is going to receive the payments from a subsecretary of the Federal Government for Sarre and Papagos and for the remaining concessions, the concession contracts allow for tolls to be increased by inflation each year.

The foreign currency position of national and foreign subsidiaries of the Entity is as follows:

d. Credit risk

Credit risk management - Credit risk refers to the risk that the counterparty to ICA fails to comply with its contractual obligations, thereby generating a financial loss for Entity. The objective of this risk management is to reduce its impact by reviewing the solvency of the Entity’s potential customers. Once contracts are underway, the credit rating of uncollected amounts is periodically evaluated and estimates are revised for allowance for doubtful accounts with corresponding entries to the statements of results and other comprehensive (loss) income in the period of the revision.

The Entity’s maximum credit risk exposure is presented in the amounts included in the table in subsection b) as well as within the past due but not impaired analysis of accounts receivable, included in Note 7.

The Entity evaluates such risk before the presentation of its offer. For public sector clients, the origin of the funds is analyzed to determine if they are governmental, state or if they come from financing. As well, the Entity evaluates the payment history of the client. Likewise, the Entity evaluates if a governmental budget exists for the project. For private clients, the Entity likewise evaluates the payment history of the client and the origin of the funds. The Entity’s credit exposure is reviewed and approved by senior management committees. The credit risk derived from cash, cash equivalents and derivative financial instruments is limited because counterparties are banks with high credit ratings assigned by credit bureaus. The financial instruments which potentially expose the Entity to credit risks are primarily composed by receivable certifications and other accounts receivable.

F-163

Claims are occasionally filed against customers for additional project costs which exceed the contract price or for amounts which were not included in the original contract price, including modification orders. This type of claim is filed for issues such as delays attributable to the customer, higher unit prices or the modification of the initial project scope, thereby resulting in additional indirect or direct costs. These claims are often subject to long arbitration or legal processes or procedures involving external experts, meaning that it is difficult to accurately forecast when they will be definitively resolved. When this occurs and it has unresolved claims, ICA can invest significant amounts of working capital in projects to cover excess costs while claims are resolved. Regarding particular modification orders, ICA can reach an agreement with the customer regarding the work scope, albeit without determining the final price. In this case, the opinion of external experts may be required to appraise unfavorable prices determined outside the Entity’s control.

The failure of customers to pay under certain projects that became pronounced at the end of 2015, have deepened lack of liquidity of the Entity, resulting in the Entity recognizing an allowance for doubtful accounts as of December 31, 2015 for Ps.6.672 million (see Note 7.a); such allowance was Ps.1,457 million and Ps.961 million as of December 31, 2014 and 2013, respectively; including an allowance for doubtful accounts of Ps.12 million at December 31, 2015, Ps.126 million at December 31, 2014 and 2013 in the Airport segment related to the bankruptcy of the airlines of the Mexicana Group. The failure to quickly recover resources from this type of claim and modification orders could have a significant adverse effect on the Entity’s liquidity and financial position. At times, even though a project may be contemplated in a governmental budget, certain line items in the budget may be cut, including related to the project.

The credit risk on liquid funds and derivative financial instruments is limited because the counterparties are banks with high credit ratings assigned by recognized rating agencies.

The Entity does not have any kind of guarantees or other credit enhancement to cover its credit risk associated with financial assets.

Other accounts receivable are composed by amounts receivable from associated companies and notes receivable. The Entity considers that these amounts will not result in a significant credit risk concentration.

e. Liquidity risk

Liquidity risk management - This risk is generated by temporary differences between the funding required by the Entity to fulfill business investment commitments, debt maturities, current asset requirements, etc., and the origin of funds generated by the regular activities of ICA, different types of bank financing and disinvestment; this disalignment of funds and obligations was aggravated in 2015 by the lack of payment on various amounts owed. The objective of ICA in the management of this risk is to maintain a balance between the flexibility, period and conditions of credit facilities contracted to manage short, medium and long-term funding requirements. In this regard, the Entity’s use of project financing and debt with limited resources described in Note 27 and the short-term financing of current assets are significant. The Operations Committee of ICA is ultimately responsible for liquidity management. This Committee has established appropriate liquidity management guidelines. The Entity manages its liquidity risk by maintaining reserves, financial facilities and adequate loans, while constantly monitoring projected and actual cash flows and reconciling the maturity profiles of financial assets and liabilities. Additionally, as mentioned in Note 27, the Entity has available credit lines for working capital.

The following table details the remaining contractual maturity for the financial liabilities of the Entity with agreed repayment periods. This table has been prepared based on the projected non-discounted cash flows of financial liabilities at the date on which ICA must make payments. The table includes projected interest cash flows such as disbursements required for the financial debt included in the consolidated statement of financial position. As interest is accrued at variable rates, the non-discounted amount is derived from interest rate curves at the end of the reporting period. Contractual maturity is based on the earliest date when ICA must make the respective payment.

The amounts forming part of the debt contracted with credit institutions include fixed and variable rate instruments. Variable-rate financial liabilities are subject to change when variable interest rates differ from the estimated interest rates determined at the end of the reporting period.

As mentioned in Note 2.a, management is considering various options, including negotiations with its current bondholders and certain suppliers in an effort to restructure its debt and other obligations. Additionally, the Entity is analyzing the feasibility of the sale of certain assets, which are not strategic for the Entity’s operation, or the partial realization of investments to obtain access to resources over the coming months.

The Entity has access to credit lines with different banking institutions for certain projects, see Note 27.

31. Stockholders’ equity

a. Equity risk management

The objectives of Entity with respect to management of equity risk is to maintain an optimum financial-net worth structure, to reduce capital costs and safeguard its capacity to continue its operations with solid indebtedness ratios.

The Entity is not subject to any externally imposed requirements for managing capital.

The Operations Committee quarterly reviews the Entity ´s equity structure. As part of this review, the Committee considers the cost of capital and the risks associated with each class of equity.

The equity structure is essentially managed through the maintenance of adequate levels of Earnings before Interest, Taxes, Depreciation and Amortization (EBITDA), which is calculated in the following manner: income (loss) attributable to controlling interests plus income attributable to non-controlling interests, income taxes, other expenses (income), net, plus the participation in the equity held in associated entities and joint ventures, plus borrowing costs, depreciation, amortization and the borrowing costs included in the cost of sales of projects financed during the construction stage.

c. At an Ordinary Shareholders’ meeting held on April 23, 2015, an increase in the reserve fund for the repurchase of the Entity’s shares for up to Ps.2,100 million was approved. At the Ordinary Shareholders’ Meeting held on April 9, 2013 and November 17, 2011, the shareholders approved an increase in the reserve fund for the purchase of Entity shares up to Ps.2,140 and Ps.1,850 million, respectively, authorizing the availability to repurchase shares of the Entity up to that maximum amounts.

a. Share plan - At December 31, 2005, the number of shares held in treasury assigned to meet the Entity’s obligation under the employee bonus plan was 9,647,899, of which at December 31, 2008, 3,308,313 shares were granted.

ICA also offered an Option Plan for executives and employees, whose term ended in 2010. Upon cancellation of the plan, 370,827 shares designated to meet the requirements of this plan were transferred to the Share Plan for executives of Empresas ICA. The balance of treasury shares designated for the Share Plan for executive of Empresas ICA as of December 31, 2015 is 495,459.

F-170

e. Equity forward – The Entity entered into an equity forward to be settled in cash with respect to 22,280,100 shares of its capital, from May 22, 2012 to August 21, 2013 in non-consecutive terms, at a weighted average strike price (“strike”) of Ps.24.99. During 2013, the instrument and the strike, were renewed, concluding its term in February 2014, see Note 26.

f. Stockholders’ equity, except restated paid-in capital and tax retained earnings, will be subject to income tax at the rate in effect when a dividend is distributed. Any tax paid on such distribution may be credited against the income tax payable or provisional payments, of the year in which the tax on the dividend is paid and the two fiscal years following such payment.

g. Retained earnings include the statutory legal reserve. The General Corporate Law requires that at least 5% of net income of the year be transferred to the legal reserve until the reserve equals 20% of capital stock at par value. The legal reserve may be capitalized but may not be distributed unless the entity is dissolved, and must replenished if it is reduced for any reason. As of December 31, 2015, 2014 and 2013, the legal reserve amounted to Ps.676, Ps.621 and Ps.563 million, respectively.

32. Share-based payment

ICA has established a share-based compensation plan for executive middle- and upper-level management. Middle- and upper-level management identified as key management personal and personnel with significant potential will obtain a stock bonus under the plan, awarded with ordinary shares of the Entity.

The number of shares granted is calculated in accordance with the performance-based formula approved by the Compensation Committee (“Committee”). The formula rewards executives and middle- and upper-management based on their individual achievements and their contribution to the Entity, evaluated based on both quantitative and qualitative criteria stemming from the following measures: performance and achievement of goals and objectives, conduct in accordance with the principles of teamwork and morals, integrity, service attitude, and achievement and adherence to the Code of Ethics and corporate policies.

The Entity has established the following policies regarding the calculation of the performance bonus: if the net income of ICA represents 4% or less of the value of stockholders’ equity or less, the bonus will not be paid, and if the net income of ICA represents more than 4%, the amount of the stock bonus may not exceed 20% of the amount of net income, which should also not exceed 4% of equity.

Once the stock bonus has been authorized by the Committee, ICA will transfer shares (either shares repurchased under ICA’s repurchase program or new shares issued for the bonus program, as approved by the shareholders) to the Administration Trust 11971-5 that was established on April 8, 1992 (“Trust”), with the National Bank of Mexico as trustee. Bonds within the Trust can be designated by the technical committee to purchase shares in the name of those who received a bonus. All dividends paid with respect to the shares included in the Trust also are placed within the Trust. At the discretion of the technical committee, dividends on shares assigned to participants in the Trust may be paid in cash or are used to purchase shares at the prevailing market price for the benefit of the respective employee. If an employee terminates is working relationship with the Entity, such employee is entitled to receive, via partial periodic payments, its respective shares; certain exceptions may be permitted to accelerate those payments to the former employee. The Trust may, but is not required to, buy the shares constituting such partial periodic payments. All dividends received with respect to the shares owned by any former employee are paid to such former employee.

Members of the administration that stop working for the Entity are entitled to receive, in annual installments, the shares credited to their accounts in the management trust. From time to time, certain exceptions may be made to these rules to allow employees that stop working for the Entity to receive shares on an accelerated basis.

For the year ended December 31, 2015, the Entity did not grant any share-based payments. During the years ended December 31, 2014 and 2013, the Entity made share-based payments of 2,974,623 and 4,335,094, shares, respectively; the shares issued in 2014 and 2013 were valued at 13.78 per share corresponding to the

F-171

theoretical value of the shares in circulation (subscribed and paid capital) at the date of their grant. The Entity recorded Ps.41 million and Ps.125 million as an increase to the common stock of the Entity. The fair value of the shares paid as a bonus to the date of grant, amounted to Ps.25.79 and Ps.33.26, respectively, according to the market value of the stock as listed on the Mexican Stock Exchange (“BMV”).

33. Non-controlling interest in consolidated subsidiaries

Non-controlling interest consist of the following:

	Year ended December 31
	2015		2014		2013
Common stock	Ps.	1,812,889	Ps.	1,417,482	Ps.	1,996,392

	Ps.	7,555,323	Ps.	5,651,150	Ps.	5,555,362

The fluctuation in the non-controlling interest mainly occurs because of the effects of dividends received and changes in controlling interest of subsidiaries. For the year ended December 31, 2015, the net increase in common stock and retained earnings and others is due to the divestiture of San Martin and the sale of the non-controlling interest of ICA OVT, partially offset by the capital repayment of GACN.

34. Assets classified as held for sale

a. As mentioned in Note 2, the Entity classified as assets available for sale, the land that was presented within investment properties as well as its investment in Arrendadora Viveica, S.A. de C.V. (“Arrendadora”). Although the agreement was finalized in 2016 (see Note 42), the criteria for assets held for sale was met as of December 31, 2015.

The Entity has received a proposal for the purchase of the land owned by Centro Sur, S.A. de C.V., which has been valued at fair value less costs to sell, if any, based on the offer received.

The Entity signed a binding agreement to sell the shares of Arrendadora, the investment has been valued at fair value less costs to seel, if any, considering the purchase price agreed in the binding agreement.

Based on the foregoing, the land of Centro Sur and assets and liabilities of Arrendadora are presented as assets held for sale and liabilities directly associated with assets held for sale in the consolidated statement of financial position as of December 31, 2015. Because Arrendadora does not represent a major line of business or geographical location, it does not qualify as a discontinued operation and its results of the year are presented as continuing operations in the consolidated statement of results and other comprehensive (loss) income.

39. Retirement benefit obligation

The liability for employees derives from the pension plan, seniority premiums and payments at the end of employment to employees upon retirement, and is determined based on actuarial computations made by external actuaries, using the projected unit credit method. Seniority premiums consist of a single payment equal to 12 day’s salary for each year of service based on the employee’s most recent salary, but without exceeding twice the current minimum wage established by law.

In 2006, the Entity created a defined benefit pension plan covering all active employees aged more than 65, who are part of the board of Empresas ICA, S.A.B. de C.V. and have a minimum of 10 years’ of service as a member of the board prior to their retirement. These individuals may exercise these benefits after the age of 55, with gradual reductions of the salaries considered for pension purposes. Beginning January 1, 2008, the plan deferred the early retirement age an additional two years, which such deferral ended in 2010. During 2012, the pension plan was further modified to provide lifelong benefits for these executive. In November 2015, three executives were paid benefits under pension plan, using all available funds on that date.

Also, in 2012, the Entity established an early retirement from age 60 for all employees, provided that they have 10 years of service with the Entity.

The plans in Mexico typically expose the Entity to actuarial risks such as: investment risk, interest rate risk, longevity risk and salary risk

Investment risk	The present value of the defined benefit plan liability is calculated using a discount rate determined by reference to long-term government bond yields. To select the discount rate, the rate of the bond yield that is similar to the duration of the obligations of labor liabilities of the Entity is considered. This rate is obtained from a company dedicated to provide updated prices for the valuation of financial instruments, as well as comprehensive calculation, reporting, analysis, and risks related to these prices, and that is regulated by the National Banking and Securities Commission. The choice of rate also considers the average days over which the employee benefits would be payable and not the maturity of the bond, which means that the discount rate will depend on the expected flow of benefit payments from plan.
Interest risk	A decrease in the bond interest rate will increase the plan liability; however, this will be partially offset by an increase in the return on the plan’s debt investments.
Longevity risk	The present value of the defined benefit plan liability is calculated by reference to the best estimate of the mortality of plan participants both during and after their employment. An increase in the life expectancy of the plan participants will increase the plan’s liability.
Salary risk	The present value of the defined benefit plan liability is calculated by reference to the future salaries of plan participants. As such, an increase in the salary of the plan participants will increase the plan’s liability.

No other post-retirement benefits are provided to these employees.

The most recent actuarial valuation of the defined benefit obligation was carried out at December 31, 2015, by Towers Watson Consultores Mexico, S.A. de C.V., which employs actuaries certified by the Colegio Nacional de Actuarios de Mexico. For the years ended December 31, 2014 and 2013, the actuarial valuer was Mercer The present value of the defined benefit obligation, and the related current service cost and past service cost, were measured using the projected unit credit method

The principal assumptions used for the purposes of the actuarial valuations were as follows:

	December 31,
	2015			2014			2013
Discount rate(s), average		6.29	%		7.17	%		7.50	%

(1) As a result of the decrease in personnel payroll by settlements, significant release of liability was originated, the favorable effect was recorded as a reduction of obligation.

(2) Relates to adjustments in actuarial assumptions for example: updating the liabilities accrued pension uncollected or an average increase of 13.29% to directors at base payroll for employees that they remained active during the year, or transfers of staff (increased obligation because they adhered to the pension plan).

The current service cost and the net interest expense for the year are included in the employee benefits expense in results.

The remeasurement of the net defined benefit liability is included in other comprehensive income.

The information below shows the most significant detail about the plans of the Entity.

The amount included in the consolidated statement of financial position arising from the Entity’s obligation in respect of its defined benefit plans is as follows:

Present value of defined benefit obligation as of December 31	Ps.	—		Ps.	156,423		Ps.	160,587

The fair value of the plan assets at the end of the reporting period for each category, are as follows:

	Fair value of plan assets
	December 31,
	2015		2014		2013
Debt instruments	Ps.	—	Ps.	156,423	Ps.	160,587

The fair values of the above debt instruments are determined based on quoted market prices in active markets.

The actual return on plan assets was Ps.9,277, Ps.11,617 and Ps.9,919 for December 31, 2015, 2014 and 2013, respectively.

Significant actuarial assumptions for the determination of the defined obligation are discount rate, expected salary increase and mortality. The sensitivity analyses below have been determined based on reasonably possible changes of the respective assumptions occurring at the end of the reporting period, while holding all other assumptions constant.

• If the discount rate is 100 basis points higher (lower), the defined benefit obligation would decrease to Ps.1,020 million (increase to Ps.1,087 million), decrease by Ps.1, 076 million (increase by Ps.1, 131 million), and decrease by Ps.1, 046 million (increase by Ps.1, 148 million), as of December 31, 2015, 2014 and 2013, respectively.

• If the expected salary growth increases (decreases) by 1%, the defined benefit obligation would increase by Ps.1,058 million (decrease by Ps.1,053 million), increase by Ps.1, 110 million (decrease by Ps.1, 096 million) and increase by Ps.1, 118 million (decrease by Ps.1, 066 million), as of December 31, 2015, 2014 and 2013, respectively.

The sensitivity analysis presented above may not be representative of the real change in the defined benefit obligation as it is unlikely that the change in assumptions would occur in isolation of one another as some of the assumptions may be correlated.

Furthermore, in presenting the above sensitivity analysis, the present value of the defined benefit obligation has been calculated using the projected unit credit method at the end of the reporting period, which is the same as that applied in calculating the defined benefit obligation liability recognized in the statement of financial position.

There was no change in the methods and assumptions used in preparing the sensitivity analysis from prior years.

There has been no change in the process used by the Entity to manage its risks from prior periods.

Obligation at December 31, 2015 is 16 years (2014: 15 and 2013: 14 years).

40. Nonmonetary transactions

During the years ended December 31, 2015, 2014 and 2013, the Entity carried out the following nonmonetary transactions, which are not reflected in its consolidated cash flow statement

a. The Entity recognized construction revenues which were exchanged for intangible assets for the year ended December 31, 2015, 2014 and 2013, for the amount of Ps.3,513 million, Ps. 3,180 million and Ps. 3,776 million, respectively. Construction costs are considered as an operating activity.

b. As of December 31, 2014 and 2013, the Entity had an increase in stockholders’ equity for Ps.77 million and Ps. 144 million, respectively, corresponding to shares delivered as share-based payment to executive middle- and upper-level management.

c. As of December 31, 2015, 2014 and 2013, the Entity acquired machinery through capital leases for the amount of Ps.1,366 million, Ps.197 million and Ps.87 million, respectively, for which an asset and liability were recorded for the same amount.

d. For the year ended December 31, 2014, the Entity credited tax paid abroad by Ps.260,236 against tax deconsolidation short-term.

41. Business segment data

a. The reportable segments are determined based on the financial information by segment which is reported internally by the Entity. Segment information is presented according to internal reports of the Entity’s business units, which are regularly reviewed by management for purposes of making operating decisions, in order to allocate resources to the segment and assess segment performance.

For the years ended December 31, 2015, 2014 and 2013, the Entity was organized into five major reportable segments which were: Civil Construction, Industrial Construction (corresponds to the Entity’s 50% investment in the joint venture ICA Fluor, and it is part of the strategic development goals of ICA), Airports, Concessions and Corporate and other.

Civil Construction

The Civil Construction segment focuses on infrastructure projects in Mexico, including the construction of roads, highways, transportation facilities (such as mass transit systems), bridges, dams, hydroelectric plants, prisons, tunnels, canals and airports, as well as on the construction, development and remodeling of large multi-storied urban buildings, including office buildings, multiple-dwelling housing developments and shopping centers. The Civil Construction segment has also pursued opportunities in other parts of Latin America, the Caribbean, Asia and the United States, and in 2011 was pursuing select opportunities outside of Mexico and performing one construction project in Panama and Colombia. The Civil Construction segment performs activities such as demolition, clearing, excavation, de-watering, drainage, embankment fill, structural concrete construction, concrete and asphalt paving, and tunneling. For the years ended December 31, 2015, 2014 and 2013, the Civil Construction segment accounted for approximately 62%, 67% and 67%, respectively, of total revenues.

Industrial Construction

The Industrial Construction segment is integrated exclusively by the 50% participation in the joint venture ICA Fluor, and it focuses on the engineering, procurement, construction, design, and commissioning of large manufacturing facilities such as power plants, chemical plants, petrochemical plants, fertilizer plants, pharmaceutical plants, steel mills, paper mills, drilling platforms, and automobile and cement factories. Fort the years ended December 31, 2015, 2014 and 2013, the industrial construction segment reported revenues for Ps.11,958 million, Ps. 6,128 million and Ps. 5,079 million, respectively. Eliminations are made in the segment information below to account only for the 50% joint control ICA has in ICA Fluor. This investment is accounted for using the equity method.

F-184

Airports

Through GACN, ICA operates 13 airports in the Central North region of Mexico pursuant to concessions granted by the Mexican government, including the Monterrey airport. For the years ended December 31, 2015, 2014 and 2013, the Airports segment amounted for 13%,10% and 12%, respectively, of total revenues. The airports serve a major metropolitan area (Monterrey), three tourist destinations (Acapulco, Mazatlan and Zihuatanejo), two border cities (Ciudad Juarez and Reynosa) and seven regional centers (Chihuahua, Culiacan, Durango, San Luis Potosi, Tampico, Torreon and Zacatecas). All of the airports are designated as international airports under Mexican law, meaning that they are all equipped to receive international flights and maintain customs, refueling and immigration services managed by the Mexican government.

Concessions

The concessions segment focuses on the construction, development, maintenance and operation of long-term concessions of toll roads, tunnels and water projects. For the years ended December 31, 2015, 2014 and 2013, this segment accounts for 22%, 20% y 21, respectively, of total revenues for the year. The construction work the Entity performs on the concessions is included in the Civil Construction segment. During 2015, ICA participated in two highways and a tunnel concessioned under construction and three operating concessioned highways; a tunnel in operation (the Acapulco tunnel), two rehabilitation centers, a bypass. Additionally, through associates and joint ventures during 2015, ICA participated in a highway under construction; 3 aqueducts, a highway and parking lots in operation, under concession.

Mexican state and municipal governments and the governments of certain foreign countries award concessions for the construction, maintenance and operation of infrastructure facilities. The Mexican government actively pursues a policy of granting concessions to private parties for the construction, maintenance and operation of highways, bridges and tunnels to promote the development of Mexico’s infrastructure without burdening the public sector’s resources and to stimulate private sector investment in the Mexican economy. A long-term concession is a license of specified duration (typically between 20 and 40 years), granted by a federal, state or municipal government to finance, build, establish, operate and maintain a public means of communication or transportation.

The return on any investment in a concession is based on the duration of the concession, in addition to the amount of toll revenues collected or government payments based on operation volume, operation and maintenance costs, debt service costs and other factors. Recovery of the investment in highway concessions is typically accomplished through the collection of toll tariffs or, if under the Public Private Partnership (PPP) contract structure, a fixed payment for highway availability (together with a smaller shadow tariff based on traffic volume), or a combination of the two methods. The return on investment in the water treatment concessions is generally based on the volume of water supplied or treated.

To finance the obligations of the projects, ICA typically provides a portion of the equity and the rest is arranged through third party financing, through loans or debt securities. Recourse on the indebtedness is typically limited to the subsidiary engaged in the project. The investment of equity is returned over time once the project is completed. Generally, ICA contributes equity to a project by accepting deferred payment of a portion of its construction contract price. Depending on the requirements of each specific infrastructure concession project, ICA typically seeks to form a consortium with entities that have expertise in different areas and that can assist us in obtaining financing from various sources.

42. Subsequent events

a. As is mentioned in Note 2, the Entity defaulted on payments of interest on its Senior Notes, which included guarantees of the subsidiaries CICASA, CONOISA, and CONEVISA, originating the default on various loans of the subsidiaries. For certain loans, shares of GACN were pledged as a guarantee; the bank institutions enforced the guarantees for the immediate payment of the total liabilities secured in 2016. The balances as of December 31, 2015 of these loans are as follows:

	Liabilities		GACN shares
Institution and borrower
Santander (Aeroinvest), (Note 27) (1)	Ps.	2,250,000		27,795,120
Deustche Bank/ Barclays (Aeroinvest), (Note 27)		1,595,261		22,334,934
Deutsche Bank AG / Corpbanca (ICASA) , (Note 21) (2)		798,124		10,827,666
Value (Aeroinvest), (Note 21)		600,000		7,721,678
Total	Ps.	5,243,385		68,679,398

(1) On the date the guarantees were executed, 2,550,475 additional shares were delivered to settle the debt, including the financial cost.

(2) The liabilities with these institutions amounted to Ps.1,147,087, the outstanding difference was documented with an unsecured loan for Ps.348,963.

(3) On the date the guarantees were executed, the value of the guarantee was superior to the related obligations. The creditor returned cash to the Entity for the amount of Ps.907.

In addition to the execution of guarantees, during February 2016, 4,386,250 GACN shares were sold, obtaining a profit of Ps.328 million.

As a result of the execution of guarantees over the shares of GACN as well as the sale described above, the equity interest of Aeroinvest in GACN was reduced. As of the date of these financial statements, Aeroinvest’s direct interest in GACN is 7.5 million of Series B shares, which represent 1.8% of the capital stock of GACN. Additionally, Aeroinvest maintains indirectly 12.5% of the capital stock of GACN through its stock holding of 74.5% in SETA. In total, Aeroinvest maintains 14.3% of interest of GACN, maintains its control and continues consolidating its financial statements.

b. In April 2016, notice was given to the Entity of the loan default for US $55 million dollars of ICA Plan, which is secured with the shares of San Martin, mentioned in Note 27. As of the date of these financial statements, the guarantee had not been enforced.

c. As is mentioned in Note 28, the Entity defaulted in its payment of its tax deconsolidation liabilities, which should have been made on March 31, 2016, resulting in the reclassification of such amounts to current liabilities for Ps.903 million.

d. As discussed in Note 22, as a result of defaults on value-added tax payments, in March 2016, the General Tax Collection Administration began an administrative enforcement proceeding against certain subsidiary entities for which the Entity has placed in guarantee, whereby it may seize certain of the subsidiaries assets for payment of the Ps. 973 million in taxes owed.

e. As a result of the financial situation of ICA, the bonding company with which Facchina operated decided not to grant bonds for the new contracts. To ensure its bonding capacity, in March 2016, Berkshire Hathaway was selected as bonding company, which requested the creation of a trust, in which all the Facchina shares were deposited as guarantee.

f. On February 22, 2016, the Entity formalized the purchase – sale agreement for 100% of the representative shares of the capital stock of Arrendadora, with Banca Mifel as trustee, and Grupo Desarrollador ZKC, as purchaser. The transaction amounted to Ps.347 million (see Note 34).

F-189

g. On February 9, 2016, Covimsa, S.A. de C.V. executed an agreement with the CKD Fomento a la Energía e Infraestructura de Mexico (EXI), through the trust EXICK, for a convertible loan of Ps.750 million. These resources will be used to complete the highway project Palmillas – Apaseo El Grande (see Note 13).

h. On January 8, 2016, the Entity was given notice of the New York Stock Exchange (NYSE), reporting that ICA no longer complied with the NYSE listing standards, because the closing average price of the ICA ADS, in a consecutive period of 30-days, was lower than U.S.$1.00 per ADS.

i. In January and February 2016, the Entity defaulted in the payment of interest of U.S.$22 million dollars and U.S.$6 million dollars related to the U.S.$500 million dollar and U.S.$150 million dollar unsecured Senior Notes.

43. Authorization for issuance of financial statements

The publication of the consolidated financial statements prepared in accordance with IFRS was authorized on April 12, 2016, by Luis Fernando Zarate Rocha, General Director of Empresas ICA, S.A.B. de C.V., and Pablo García Aguilar, Administration and Finance Vicepresident of the Entity, and on April 29, 2016 were approved by the Shareholders of the Entity.

Selected Information to Separate Financial Statements

For the years ended December 31, 2015 and 2014

(Thousands of Mexican pesos, except as otherwise indicated)

1. Nature of business

Empresas ICA, S.A.B. de C.V. (“ICA” or, the Entity”) is a holding company incorporated in Mexico with over 68 years experience, the subsidiaries of which are engaged in a wide range of construction and related activities including the construction of infrastructure facilities as well as industrial, urban and housing construction, for both the Mexican public and private sectors. ICA’s subsidiaries are also involved in the construction, maintenance and operation of highways, bridges and tunnels granted by the Mexican government and foreign governments under concessions. Through its subsidiaries, the Entity also manages and operates airports. In addition, some of ICA’s subsidiaries are engaged in real estate and housing development. Through its associated entities, since 2012, ICA provided mining related services, such as exploration and exploitation of deposits for others, transportation and other mining-related activities. ICA’s shares are traded on the Mexican Stock Exchange and the New York Stock Exchange, see Note 42. Its registered address is 36 Boulevard Manuel Avila Camacho, Piso 15, Lomas de Chapultepec, 11000 Mexico, D. F.

As of December 31, 2015, the Entity has no employees; consequently it is not subject to labor-obligations.

2. Going concern

During December 2015, the Entity defaulted on the U.S.$31 million interest payment on its U.S.$700 million Senior Notes maturing in 2024. Subsequent to year end, the Entity also defaulted on U.S.$22 million and U.S.$6 million in interest payments on its U.S.$500 million Senior Notes maturing in 2021 and its U.S.$150 million Senior Notes, maturing in 2017, respectively.

The Entity’s failure to pay the interest on these Senior Notes resulted in cross-defaults of certain other long-term debt in December 2015 and subsequently in 2016, which resulted in the guarantees existing under those secured loans being executed by the respective bank creditors during the first quarter of 2016. See footnote 42. These loans, together with the obligations of the Senior Notes, are presented in current liabilities at December 31, 2015, in the Entity’s consolidated statement of financial position. Additionally, the Entity has experienced a general delay in payments to certain service suppliers and creditors and taxes, as well as a reduction of operations and personnel adjustments.

At December 31, 2015, short-term liabilities exceed current assets by Ps.24.4 billion pesos. Additionally, the Entity has suffered net losses of Ps.6.2 million and Ps.2.5 million during the last two years. These events and results raise substantial doubt about the Entity’s ability to continue as a going concern. The accompanying financial statements have been prepared under the assumption that the Entity will continue as a going concern, which assumes the realization of its assets and the settlement of its liabilities and obligations in the normal course of business. Consequently, the accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Management is considering various options, including negotiations with its current bondholders and certain suppliers in an effort to restructure its debt and other obligations as well as seek additional financing. Additionally, the Entity is analyzing the feasibility of the sale of certain assets, which are not strategic for the Entity’s operation, or the partial realization of investments to allow the Entity to obtain access to resources over the coming months. Moreover, the Entity has implemented a series of operating restructuring measures, including a reduction of personnel costs, appointment of a Restructuring Director, changes involving key management personnel, and the creation of trusts to ensure the adequate utilization of funds assigned to certain construction projects. The Entity has hired external advisors to advise the Entity on the best restructuring strategy based on the Entity’s finances, liquidity requirements, payment capacity and operations.

G-7

Although the Entity’s management is focused on making its operations profitable, concluding and executing its restructuring plan and obtaining new financing sources, the outcome of the restructuring process and the implications it may have for parties with an interest in the Entity, such as its stockholders, creditors, suppliers, customers and employees, cannot be guaranteed, nor can the successful outcome of the restructuring plan be assured.

3. Convenience translation

Solely for convenience of readers, peso amounts included in the financial statements as of December 31, 2015 and for the year then ended have been translated into U.S. dollar amounts at exchange rate of Ps.17.3398 pesos per U.S. dollar, as published by Banco de Mexico, S.A. Such translation should not be construed as a representation that the Mexican peso amounts have been, could have been or could, in the future, be converted into U.S. dollars at such rate or any other rate.

4. Notes payable

Notes payable consist of the following:

	December 31,
	2015		2014
Payable in U.S. dollars:
Loan granted to ICA in November 2014, for U.S.$46 million dollars, accruing interest at fixed rate 7.5%. The loan matures in November 16, 2015. Costs and financing commissions of Ps.40,322.

5. Long-term debt

Payable in U.S. dollars:
In May 2014, ICA placed senior notes for a principal amount of U.S.$700 million dollars, maturing in 2024. Debt instruments have an annual interest rate of 8.875%, interest is paid semi-annually.

As of December 31, 2015 debt corresponds to U.S.$150 million, resulting from the operation is described below:
In July 2012, ICA placed senior notes for a principal amount of U.S.$350 million dollars, maturing in 2017. Debt instruments have an annual interest rate of 8.375%, payable semi-annually, resulting in a yield to maturity of 8.625%. U.S.$200 million dollars were prepaid with the resources obtained from senior notes placed in May 2014. This early settlement caused the payment of a premium to the bondholders for U.S.$13.5 million dollars which was recorded in financial cost in 2014. (1)		2,600,970			2,210,220
In February 2011, ICA placed senior notes for a principal amount of U.S.$500 million dollars, with a coupon of 8.90% and maturing in 2021. (1)		8,669,900			7,367,400

(1) These debt instruments were issued by ICA as unsecured notes, with Constructoras ICA, S.A. de C.V. (“CICASA”), Controladora de Operaciones de Infraestructura, S.A. de C.V. (“CONOISA”) and Controladora de Empresas de Vivienda, S.A. de C.V. (“CONEVISA”), as guarantors.

b. The scheduled maturities of long-term debt as of December 31, 2015, is as follow:

At December 31, 2015	1 year		Up to 2 years		Up to 3 years		Up to 4 years		Up to 5 years		Up to 6 years and thereafter		Total

(1) Amounts before commissions and issuance costs.

c. Long-term debt issued by Entity includes various covenants that restrict the ability to incur additional indebtedness and capital lease obligations, issue guarantees, sell fixed and other non-current assets and make capital distributions, as well as require compliance with certain other financial ratios. These financial ratios include: the ratio of total liabilities to equity; the ratio of current assets to current liabilities; the ratio of current assets less affiliated accounts receivable to current liabilities; and the ratio of operating earnings plus depreciation to net financing expenses.

d. As mentioned in Note 2, due to the liquidity problems experienced by the Entity, which worsened in the last quarter of 2015, ICA management elected to use its resources mainly for its business operations and project execution rather than for paying the coupon interest of its U.S.$700 million Senior Notes with maturity in 2024, for the amount of U.S.$31 million that were due at the end of the month of December in 2015.

As a result of defaulting on this interest payment, cross defaults occurred in certain other long-term bank liabilities, which in certain cases, the related guarantees were enforced by the bank creditors in the first months of 2016. By virtue of the above, the Senior Note liabilities for the amount of Ps.22,809,107, after fees and financing expenses, were reclassified to the short-term liabilities in the balance sheet of the Entity as of December 31, 2015.

G-9

6. Guarantees

The Entity has granted guarantees for the amount of U.S. $459 million, equivalent to Ps.7.952 billion, to some of its related parties for bank liabilities contracted for them, of which Ps.1.350 billion are related to short-term loans and Ps.6.582 billion are related to long-term loan.

7. Subsequent events

a. The Entity defaulted on its payment of its tax deconsolidation liabilities, which should have been made on March 31, 2016, resulting in the reclassification of such amounts to current liabilities for Ps.903 million as of such date.

b. On January 8, 2016, the Entity was given notice of the New York Stock Exchange (NYSE), reporting that ICA no longer complied with the NYSE listing standards, because the closing average price of the ICA ADS, in a consecutive period of 30-days, was lower than U.S.$1.00 per ADS.

c. In January and February 2016, the Entity defaulted on the payment of interest of U.S.$22 million dollars and U.S.$6 million dollars related to the U.S.$500 million dollar and U.S.$150 million dollar unsecured Senior Notes.

Independent Auditors’ Report to the Board of Directors and Partners of ICA Fluor Daniel, S. de R. L. de C. V.

We have audited the accompanying consolidated financial statements of ICA Fluor Daniel, S. de R. L. de C. V. and Subsidiaries (the “Entity”), which comprise the consolidated statements of financial position as of December 31, 2015 and 2014, and the related consolidated statements of income and other comprehensive income (loss), changes in stockholders’ equity and cash flows for the years ended December 31, 2015 and 2014, and the related notes to the consolidated financial statements.

Management’s Responsibility for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Responsibility of the Independent Auditors

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the Entity’s preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Notes to Consolidated Financial Statements

For the years ended December 31, 2015, 2014 and 2013

(Thousands of Mexican pesos and thousands of American dollars, except as otherwise indicated)

1. Activities

ICA Fluor Daniel, S. de R. L. de C. V. (“ICA FD” or together with its subsidiaries, the “Entity”) was incorporated on March 16, 1978 under Mexican laws on March 16, 1978 and is primarily engaged in all types of engineering activities, which include construction, procurement, engineering, and installation services related to all types of industrial facilities (civil, electromechanical and maritime), as well as project management services. Until December 2014, the Entity was direct 51% directly owned by Constructoras ICA, S. A. de C. V. (CICASA); as a result of a contribution in shares of CICASA to Ingenieros Civiles Asociados, S.A. de C.V., the latter became the holder of the shares of the Entity directly and thus is indirectly owned by Empresas ICA, S. A. B. de C. V. (“ICA”) and 49% directly owned by Fluor Daniel México, S. A. (“Fluor Daniel”), which is a subsidiary of Fluor Inc., a U.S. entity. Accordingly, the Entity is a joint venture between ICA and Fluor Daniel. Its registered address is Dakota # 95, Colonia Nápoles, C.P. 03810 Benito Juárez, México, D. F.

2. Significant Events

The Entity entered into the following new contracts in 2015:

Customer	Project	Backlog at December 31, 2015	Termination date of the contract
PEMEX Trasformación Industrial	DUBA Madero Hydrosulfuric plants	Ps.17,340,967	October 2018
PEMEX Refinación	Tula Coker Plant	15,441,683	April 2018
PEMEX Trasformación Industrial	Tula – Package of 4 Integration and Auxiliary Service Works	18,931,792	June 2018
TAG Pipelines Sur, S. de R.L. de C.V.	Los Ramones Pipeline	2,146,918	October 2016

3. Basis of presentation and consolidation

a. Statement of compliance

The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS), including its amendments and interpretations, as issued by the International Accounting Standards Board (“IASB”).

b. Basis of measurement

The consolidated financial statements have been prepared on the historical cost basis except for the derivative financial instruments which are recorded at fair value.

H-13

i. Historical cost

Historical cost is generally based on the fair value of the consideration given in exchange for goods and services.

ii. Fair value

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, regardless of whether that price is directly observable or estimated using another valuation technique. In estimating the fair value of an asset or a liability, the Entity takes into account the characteristics of the asset or liability if market participants would take those characteristics into account when pricing the asset or liability at the measurement date. Fair value for measurement and/or disclosure purposes in these consolidated financial statements is determined on such a basis, except for share-based payment transactions that are within the scope of IFRS 2, leasing transactions that are within the scope of IAS 17, and measurements that have some similarities to fair value but are not fair value, such as net realizable value in IAS 2 or value in use in IAS 36 Impairment of Assets.

In addition, for financial reporting purposes, fair value measurements are categorized into Level 1, 2 or 3 based on the degree to which the inputs to the fair value measurements are observable and the significance of the inputs to the fair value measurement in its entirety, which are described as follows:

• Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date;

• Level 2 inputs are inputs, other than quoted prices included within Level 1, that are observable for the asset or liability, either directly or indirectly; and

• Level 3 inputs are unobservable inputs for the asset or liability.

c. Convenience translation

Solely for convenience of readers, peso amounts included in the consolidated financial statements as of December 31, 2015 and for the year then ended have been translated into U.S. dollar amounts at exchange rate of Ps.17.3398 pesos per U.S. dollar, FIX rate as published by Banco de Mexico, S.A. Such translation should not be construed as a representation that the Mexican peso amounts have been, could have been or could, in the future, be converted into U.S. dollars at such rate or any other rate.

d. Reporting currency

The Mexican peso, legal currency of the United Mexican States is the currency in which the consolidated financial statements are presented. Transactions in currencies other than the peso are recorded in accordance with established policies described in Note 4.c.

e. Consolidated statements of income and other comprehensive income

The Entity chose to present the consolidated statements of income and other comprehensive income in a single statement, including separate lines for gross profit and operating income, in accordance with practices of the industry. Costs and expenses were classified according to their function.

f. Basis of consolidation

The consolidated financial statements incorporate the financial statements of ICA FD and entities controlled by the Entity. Control is achieved when the Entity:

• Has power over the investee;

• Is exposed, or has rights, to variable returns from its involvement with the investee; and

• Has the ability to use its power to affect its returns.

H-14

The Entity reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above.

When the Entity has less than a majority of the voting rights of an investee, it has power over the investee when the voting rights are sufficient to give it the practical ability to direct the relevant activities of the investee unilaterally. The Entity considers all relevant facts and circumstances in assessing whether or not the Entity’s voting rights in an investee are sufficient to give it power, including:

• The size of the Entity’s holding of voting rights relative to the size and dispersion of holdings of the other vote holders;

• Potential voting rights held by the Entity, other vote holders or other parties;

• Rights arising from other contractual arrangements; and

• Any additional facts and circumstances that indicate that the Entity has, or does not have, the current ability to direct the relevant activities at the time that decisions need to be made, including voting patterns at previous shareholders’ meetings.

Consolidation of a subsidiary begins when the Entity obtains control over the subsidiary and ceases when the Entity loses control of the subsidiary. Specifically, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated statement of income and other comprehensive income from the date the Entity gains control until the date when the Entity ceases to control the subsidiary.

Profit or loss and each component of other comprehensive income are attributed to the owners of the Entity and to the non-controlling interests. Total comprehensive income of subsidiaries is attributed to the owners of the Entity and to the non-controlling interests even if this results in the non-controlling interests having a deficit balance.

The non-controlling interests in equity of subsidiaries are presented separately as “non-controlling interests” in the consolidated statements of financial position, within the stockholders’ equity section, and the consolidated statements of income and other comprehensive income.

When necessary, adjustments to the financial statements of subsidiaries are made to align its accounting policies in accordance with the accounting policies of the Entity.

The financial statements of the companies that are included in the consolidation are prepared as of December 31 of each year.

All significant intercompany balances and transactions have been eliminated on consolidation.

Changes in the Entity’s ownership interests in subsidiaries

Changes in the Entity’s ownership interests in subsidiaries that do not result in the Entity losing control over the subsidiaries are accounted for as equity transactions. The carrying amounts of the Entity’s interests and the non-controlling interests are adjusted to reflect the changes in their relative interests in the subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in equity and attributed to owners of the Entity.

When the Entity loses control of a subsidiary, a gain or loss is recognized in profit or loss and is calculated as the difference between (i) the aggregate of the fair value of the consideration received and the fair value of any retained interest and (ii) the previous carrying amount of the assets (including goodwill), and liabilities of the subsidiary and any non-controlling interests. The amounts previously recognized in other comprehensive income and accumulated in equity are accounted for as if the Entity had directly disposed of the relevant assets (i.e. they are reclassified to profit or loss or transferred directly to retained earnings). The fair value of any investment retained in the former subsidiary at the date when control is lost is regarded as the fair value on initial recognition for subsequent accounting under IAS 39, Financial Instruments: Recognition and Measurement (“IAS 39”) or, when applicable, the cost on initial recognition of an investment in an associate or a jointly controlled entity.

H-15

4. Significant accounting policies

The consolidated financial statements are prepared in accordance with IFRS as issued by the IASB. Preparation of financial statements under IFRS requires management of the Entity to make certain estimates and use assumptions to value certain of the items in the consolidated financial statements as well as their related disclosures required therein. The areas with a high degree of judgment and complexity or areas where assumptions and estimates are significant in the consolidated financial statements are described in Note 5. The estimates are based on information available at the time the estimates are made, as well as the best knowledge and judgment of management based on experience and current events. However, actual results could differ from those estimates. The Entity has implemented control procedures to ensure that its accounting policies are appropriate and are properly applied. Although actual results may differ from those estimates, the Entity’s management believes that the estimates and assumptions used were adequate under the circumstances.

The consolidation requirements, accounting policies and valuation methods used in preparing the consolidated financial statements as of and for the year ended December 31, 2015 are the same as those applied in the consolidated financial statements for 2014 and 2013.

a. Application of new and revised IFRS

i) Effective January 1, 2015, the Entity adopted the following International Financial Reporting Standards and interpretations in its consolidated financial statements:

– Amendments to IAS 19, Defined Benefit Plans: Employee Contributions

– Annual Improvements to IFRSs, 2010-2012 Cycle

– Annual Improvements to IFRSs, 2011-2013 Cycle

The Entity does not provide contributions to its defined benefit plans. Therefore, the application of Amendments to IAS 19 has had no impact on the disclosures or the amounts recognized in the consolidated financial statements. Also the application of IFRS Annual Improvements to the 2010-2012 and 2011-2013 cycle did not have a significant impact on the consolidated financial statements.

ii) The Entity has not applied the following new and revised IFRSs that have been issued but are not yet effective:

– IFRS 9, Financial Instruments (“IFRS 9”) ⁽³⁾

– IFRS 15, Revenue from Contracts with Customers ⁽³⁾

– IFRS 16, Leases ⁽⁴⁾

– Amendments to IFRS 11, Accounting for Acquisitions of Interests in Joint Operations ⁽¹⁾

– Amendments to IAS 1, Disclosure Initiative ⁽¹⁾

– Amendments to IAS 16 and IAS 38, Clarification of Acceptable Methods of Depreciation and Amortization ⁽¹⁾

– Amendments to IFRS 10, IFRS 12, and IAS 28 Investment Entities: Applying the Consolidation Exception ⁽¹⁾

– Annual Improvements to IFRSs 2012-2014 Cycle ⁽¹⁾

– Amendments to IAS 12 Income Taxes ⁽²⁾

– Amendments to IAS 7 (Cash Flow Statement) Disclosure Initiative ⁽²⁾

¹ Effective for annual periods beginning on or after July 1, 2016, with earlier application permitted.

³ Effective for annual periods beginning on or after January 1, 2018, with earlier application permitted.

⁴ Effective for annual periods beginning on or after January 1, 2019, with earlier application permitted.

IFRS 9 Financial Instruments

IFRS 9 issued in November 2009 introduced new requirements for the classification and measurement of financial assets. IFRS 9 was subsequently amended in October 2010 to include requirements for the classification and measurement of financial liabilities and for derecognition, and in November 2014 to include the new requirements for general hedge accounting. Another revised version of IFRS 9 was issued in July 2014 mainly to include a) impairment requirements for financial assets and b) limited amendments to the classification and measurement requirements by introducing a ‘fair value through other comprehensive income’ (FVTOCI) measurement category for certain simple debt instruments.

Key requirements of IFRS 9:

• All recognized financial assets that are within the scope of IAS 39 Financial Instruments: Recognition and Measurement are required to be subsequently measured at amortized cost or fair value. Specifically, debt investments that are held within a business model whose objective is to collect the contractual cash flows, and that have contractual cash flows that are solely payments of principal and interest on the principal outstanding are generally measured at amortized cost at the end of subsequent accounting periods. Debt instruments that are held within a business model whose objective is achieved both by collecting contractual cash flows and selling financial assets, and that have contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding, are measured at FVTOCI. All other debt investments and equity investments are measured at their fair value at the end of subsequent accounting periods. In addition, under IFRS 9, entities may make an irrevocable election to present subsequent changes in the fair value of an equity investment (that is not held for trading) in other comprehensive income, with only dividend income generally recognized in profit or loss.

• With regard to the measurement of financial liabilities designated as at fair value through profit or loss, IFRS 9 requires that the amount of change in the fair value of the financial liability that is attributable to changes in the credit risk of that liability is presented in other comprehensive income, unless the recognition of the effects of changes in the liability’s credit risk in other comprehensive income would create or enlarge an accounting mismatch in profit or loss. Changes in fair value attributable to a financial liability’s credit risk are not subsequently reclassified to profit or loss. Under IAS 39, the entire amount of the change in the fair value of the financial liability designated as fair value through profit or loss is presented in profit or loss.

• In relation to the impairment of financial assets, IFRS 9 requires an expected credit loss model, as opposed to an incurred credit loss model under IAS 39. The expected credit loss model requires an entity to account for expected credit losses and changes in those expected credit losses at each reporting date to reflect changes in credit risk since initial recognition. In other words, it is no longer necessary for a credit event to have occurred before credit losses are recognized.

• The new general hedge accounting requirements retain the three types of hedge accounting mechanisms currently available in IAS 39. Under IFRS 9, greater flexibility has been introduced to the types of transactions eligible for hedge accounting, specifically broadening the types of instruments that qualify for hedging instruments and the types of risk components of non-financial items that are eligible for hedge accounting. In addition, the effectiveness test has been overhauled and replaced with the principle of an ‘economic relationship’. Retrospective assessment of hedge effectiveness is also no longer required. Enhanced disclosure requirements about an entity’s risk management activities have also been introduced.

The Entity is in the process of determining the potential impacts that will result in its consolidated financial statements for the adoption of this standard.

IFRS 15, Revenue from Contracts with Customers

In May 2014, IFRS 15 was issued which establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. IFRS 15 will supersede the current revenue recognition guidance including IAS 18 Revenue, IAS 11 Construction Contracts and the related Interpretations when it becomes effective.

The core principle of IFRS 15 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Specifically, the Standard introduces a 5-step approach to revenue recognition:

• Step 1: Identify the contract(s) with a customer.

• Step 2: Identify the performance obligations in the contract.

• Step 3: Determine the transaction price.

• Step 4: Allocate the transaction price to the performance obligations in the contract.

• Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

Under IFRS 15, an entity recognizes revenue when (or as) a performance obligation is satisfied, i.e. when ‘control’ of the goods or services underlying the particular performance obligation is transferred to the customer. Far more prescriptive guidance has been added in IFRS 15 to deal with specific scenarios. Furthermore, extensive disclosures are required by IFRS 15.

The Entity is in the process of determining the potential impacts that will result in its consolidated financial statements for the adoption of this standard.

IFRS 16 Leases

IFRS 16 (Leases) was issued in January 2016 and supersedes IAS 17 (Leases) and related interpretations. This new standard requires that most leases be presented in the statement of financial position for lessees under a single model, eliminating the distinction between operating and finance leases. Lessor accounting, however, remains largely unchanged and the distinction between operating and finance leases remains in effect. IFRS 16 is effective for periods beginning on or after January 1, 2019, with earlier adoption permitted if IFRS 15 has also been applied.

Under IFRS 16, a lessee recognizes a right-of-use asset and a lease liability. The right-of-use asset is treated similarly to other non-financial assets and depreciated accordingly and the liability accrues interest. This will typically produce a front-loaded expense profile (whereas operating leases under IAS 17 would typically have had straight-line expenses) as an assumed linear depreciation of the right-of-use asset and the decreasing interest on the liability will lead to an overall decrease of expense over the reporting period.

In addition, the financial liability is initially measured at the present value of the lease payments payable over the lease term, discounted at the rate implicit in the lease if the rate can be readily determined. If the rate cannot be readily determined, the lessee shall use their incremental borrowing rate.

However, a lessee may elect to account for lease payments as an expense on a straight-line basis over the lease term for leases with a lease term of 12 months or less and containing no purchase options (this election is made by class of underlying asset); and leases where the underlying asset has a low value when new, such as personal computers or small items of office furniture (this election can be made on a lease-by- lease basis).

IFRS 16 establishes different transitional provisions, including retrospective application or the modified retrospective application where the comparative period is not restated.

The Entity is in the process of assessing the potential impact that the adoption of this standard could have in its consolidated financial statements.

H-18

Amendments to IFRS 11 Accounting for Acquisitions of Interests in Joint Operations

The amendments to IFRS 11 provide guidance on how to account for the acquisition of a joint operation that constitutes a business as defined in IFRS 3 Business Combinations. Specifically, the amendments state that the relevant principles on accounting for business combinations in IFRS 3 and other standards (e.g. IAS 36 Impairment of Assets regarding impairment testing of a cash-generating unit to which goodwill on acquisition of a joint operation has been allocated) should be applied. The same requirements should be applied to the formation of a joint operation if and only if an existing business is contributed to the joint operation by one of the parties that participate in the joint operation.

Entity’s management does not anticipate that the application of these amendments to IFRS 11 will have a material impact on its consolidated financial statements.

Amendments to IAS 1 Disclosure Initiative

The amendments to IAS 1 give some guidance on how to apply the concept of materiality in practice. Entity’s management does not anticipate that the application of these amendments to IAS 1 will have a material impact on its consolidated financial statements.

Amendments to IAS 16 and IAS 38 Clarification of Acceptable Methods of Depreciation and Amortization

The amendments to IAS 16 prohibit entities from using a revenue-based depreciation method for items of property, plant and equipment. The amendments to IAS 38 introduce a rebuttable presumption that revenue is not an appropriate basis for amortization of an intangible asset. This presumption can only be rebutted in the following two limited circumstances:

• When the intangible asset is expressed as a measure of revenue; or

• When it can be demonstrated that revenue and consumption of the economic benefits of the intangible asset are highly correlated.

Currently, the Entity uses the straight-line method for depreciation and amortization of property, and furniture, office equipment and vehicles and intangible assets for airport concessions; for machinery, the Entity uses the method of hours of use. Amortization of intangible assets for highway concessions is determined based on vehicle flow.

Entity’s management believes that the methods used are the most appropriate to reflect the consumption of the economic benefits inherent in the respective assets and accordingly, does not anticipate that the application of these amendments will have a material impact on the Entity’s consolidated financial statements.

Amendments to IAS 12 Income Taxes

The amendments to IAS 12 (Income Taxes), clarify that unrealized losses in debt instruments measured at fair value and for tax purposes measured at cost, originate a temporal difference, regardless if the instrument holder expects to recover the book value of the instrument through its sale or its use. In addition, they specify that the book value in an asset does not limit the estimation of probable future taxable profits and that when comparing the deductible temporary differences with future taxable profits, the latter exclude tax deductions that would result from the reversal of the above mentioned deductible temporary differences. These amendments are effective for annual periods starting from January 1, 2017, with retrospective application, although early adoption is permitted.

The Entity is in the process of assessing the potential impact that the adoption of these amendments could have in its consolidated financial statements.

H-19

Amendments to IAS 7 (Cash Flow Statement) Disclosure Initiative

Amendments to IAS 7 (Cash Flow Statement) require separate disclosure of the following changes in liabilities that arise from financing activities:

(i) changes in cash flows from financing activities;

(ii) changes by acquisition or loss of control in subsidiaries or other businesses;

(iii) exchange rate fluctuations;

(iv) changes in fair values; and other changes.

A way of complying with the new requirement is through a reconciliation between the opening and final balance of liabilities in the statement of financial position that arise from financing activities. Liabilities arising from financing activities are those whose cash flows are classified, or that will be classified in the future, such as financing activities cash flows in the statement of cash flow. The new disclosure requirements also apply to changes in financial assets as long as comply with the same definition.

These amendments are effective for annual periods beginning on January 1, 2017, with early adoption permitted, and entities are not require to submit comparative information when applied for the first time.

The Entity is in the process of assessing the potential impact that the adoption of these amendments could have in its consolidated financial statements.

Annual Improvements to IFRSs 2012-2014 Cycle

The Annual Improvements to IFRSs 2012-2014 Cycle include a number of amendments to various IFRSs, which are summarized below.

The amendments to IFRS 5 introduce specific guidance in IFRS 5 for when an entity reclassifies an asset (or disposal group) from held for sale to held for distribution to owners (or vice versa). The amendments clarify that such a change should be considered as a continuation of the original plan of disposal and hence requirements set out in IFRS 5 regarding the change of sale plan do not apply. The amendments also clarify the guidance for when held-for-sale accounting is discontinued.

The amendments to IFRS 7 provide additional guidance to clarify whether a servicing contract is continuing involvement in a transferred asset for the purpose of the disclosures required in relation to transferred assets.

The amendments to IAS 19 clarify that the rate used to discount post-employment benefit obligations should be determined by reference to market yields at the end of the reporting period on high quality corporate bonds. The assessment of the depth of a market for high quality corporate bonds should be at the currency level (i.e. the same currency as the benefits are to be paid). For currencies for which there is no deep market in such high quality corporate bonds, the market yields at the end of the reporting period on government bonds denominated in that currency should be used instead.

The Entity’s management does not anticipate that the application of these amendments to IFRS will have a material impact on the Entity’s consolidated financial statements.

b. Restatement of disclosures

- The amounts disclosed in the aging of balances receivable from customers that are considered past due but not impaired as disclosed in Note 7.b has been modified to exclude those amounts for cost and estimated earnings in excess of billings on uncompleted contracts. The Entity generally does not bill the cost and estimated earnings in excess of billings on uncompleted contracts until there is a contractual right to do so, which usually happens with customer approval. Therefore, these amounts should not be part of receivables past due but not impaired. The original and modified disclosures are as follows:

H-20

Aged up to 120 days	Ps.	317,544
Aged 120 to 360 days		1,523,089

Total	Ps.	17,827

c. Operations and transactions in foreign currency

Translation of financial statements of foreign operations

The individual financial statements of each subsidiary of the Entity are presented in the currency of the primary economic environment in which the entity operates (its functional currency). To consolidate the financial statements of foreign subsidiaries, their financial information is translated into Mexican pesos (the reporting currency), considering the following methodology:

The operations in which the functional currency and the recording currency are the same, the financial statements of the entity are translated to the reporting currency using the following exchange rates: i) the closing exchange rate in effect at the date of the statement of financial position for assets and liabilities, ii) historical exchange rates for stockholders’ equity as well as revenues, costs and expenses. Translation effects are recorded in other comprehensive income.

When the functional currency of a foreign operation differs from the recording currency, before applying the terms of the preceding paragraph, the recording currency must be converted to the functional currency by using the following methodology: monetary assets and liabilities are converted by using the exchange rate in effect at the date of the statement of changes in financial position, while nonmonetary assets and liabilities, stockholders’ equity, income, costs and expenses must be considered at the historical exchange rate. Any differences arising from this method must be recognized in the results of the year.

On the disposal of a foreign operation, all of the accumulated exchange differences in respect of that operation attributable to the Entity are reclassified to profit or loss in the year of disposal.

In relation to a partial disposal of a subsidiary that includes a foreign operation (that does not result in the Entity losing control over the subsidiary), the proportionate share of accumulated exchange differences are re-attributed to non-controlling interests and are not recognized in profit or loss. For all other partial disposals (i.e. partial disposals of associates or joint arrangements that do not result in the Entity losing significant influence or joint control), the proportionate share of the accumulated exchange differences is reclassified to results.

Goodwill and fair value adjustments to identifiable assets acquired and liabilities assumed through acquisition of a foreign operation are treated as assets and liabilities of the foreign operation and translated at the rate of exchange prevailing at the end of each reporting period. Exchange differences arising are recognized in other comprehensive income.

H-21

Foreign currency transactions

In preparing the financial statements, transactions in currencies other than the functional currency of the entity foreign currency transactions are recorded at the exchange rate in effect at the date of the transaction date. Monetary assets and liabilities denominated in foreign currency are translated into Mexican pesos at the exchange rate prevailing at the end of the reporting period. Non-monetary items carried at fair value denominated in foreign currency are converted at the exchange rates prevailing at the date the fair value was determined. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated.

Exchange differences on monetary items are recognized in profit or loss in the period in which they arise except for:

• Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the cost of those assets when they are regarded as an adjustment to interest costs on those foreign currency borrowings.

• Exchange differences on transactions entered into in order to hedge certain foreign currency risks (see Note 4n. below for hedging accounting policies).

• Exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither planned nor likely to occur (therefore forming part of the net investment in the foreign operation), which are recognized initially in other comprehensive income and reclassified from equity to profit or loss on repayment of the monetary items.

d. Cash and cash equivalents

Cash and cash equivalents consist mainly of bank deposits in checking accounts and short-term investments, highly liquid and easily convertible into cash, maturing within three months as of their acquisition date, which are subject to immaterial value change risks. Cash is stated at nominal value and cash equivalents are measured at fair value.

e. Inventories of building materials

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the average cost method. Net realizable value represents the estimated selling price for inventories less all estimated costs of completion and costs necessary to make the sale.

Reductions to the value of inventories are comprised of estimates representing the impairment of inventories.

H-22

f. Property, machinery and equipment

Expenditures for property, machinery and equipment are capitalized and valued at acquisition cost.

Depreciation is recognized so as to write off the cost of assets (other than freehold land and properties under construction). Depreciation of property, machinery and equipment is calculated using the straight-line method over the useful life of the asset, taking into consideration the related asset’s residual value. Depreciation begins in the month in which the asset is placed in service. The useful lives of assets are as follows:

	Useful lives (years)
Buildings	40
Other construction	27
Machinery and operating equipment	2
Minor machinery	3
Vehicles	3
Furniture and equipment	10
Computers	3
Communication equipment	10
Leasehold improvements	Contract term

Financing costs incurred during the construction and installation of property, machinery and equipment are capitalized.

Residual values, useful lives and depreciation methods are reviewed at the end of each year and adjusted prospectively if applicable. If the depreciation method is changed, this is recognized in retrospectively.

The depreciation of property, machinery and equipment is recorded in results. Land is not depreciated.

Disposal of assets

The gain or loss on the sale or retirement of an item of property, machinery and equipment is calculated as the difference between the proceeds from the sale and the carrying value of the asset, and is recognized in income when all risks and rewards of ownership of the asset is transferred to the buyer, which generally occurs when ownership of the asset is transferred to the buyer.

Replacements or renewals of complete items that extend the useful life of the asset, or its economic capacity are recognized as an increase to property, machinery and equipment, with the consequent withdrawal or derecognition of the replaced or renewed.

Construction in progress

Construction in progress is carried at cost less any recognized impairment loss. Cost includes professional fees and, in the case of qualifying assets, borrowing costs capitalized in accordance with the accounting policy of the Entity. Such properties are classified to the appropriate categories of property, machinery and equipment when completed and ready for intended use. The depreciation of these assets, as well as other properties, begins when the assets are ready for use.

Subsequent costs

Subsequent costs form part of the value of the asset or are recognized as a separate asset only when it is probable that such disbursement represents an increase in productivity, capacity, efficiency or an extension of the life of the asset and the cost of the item can be determined reliably. All other expenses, including repairs and maintenance are recognized in comprehensive income as incurred.

Assets held under finance leases are depreciated based on their estimated as own assets useful life; however, if there is no reasonable certainty that the Company will obtain ownership of the asset at the end of the lease term, the assets fully depreciated over its useful life or the lease term, the minor.

g. Leasing

Leases are classified as finance leases whenever the terms of the contract lease transfer substantially all the risks and rewards of ownership to the lessee. All other leases are classified as operating leases.

H-23

Financial Leasing

In financial leasing where the Entity is the lessee, assets are initially recognized as assets of the Entity at their fair value at the inception of the lease or, if lower, at the present value of the minimum lease payments. The liability to the lessor is included in the statement of financial position as long-term leasing arrangements.

Lease payments are apportioned between finance expenses and reduction of the lease obligation so as to achieve a constant rate of interest on the remaining balance of the liability. Finance expenses are recognized immediately in profit or loss, unless they are directly attributable to qualifying assets, in which case they are capitalized in accordance with the Entity’s general policy for borrowing costs (see paragraph h).

Assets held under finance leases are depreciated over their estimated useful lives on the same basis as owned assets.

Operating Leasing

As lessor

Rental income from operating leases is recognized on a straight-line basis over the term of the relevant lease. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized in profit using the same criteria used for the recognition of lease income.

As lessee

Any payment or collection made upon execution of an operating lease is treated as an advanced payment or collection that is recognized in results over the lease term, as the benefits of the leased asset are received or transferred.

The costs and expenses arising under operating leases are recognized in results using the straight line method during the term of the lease. Contingent rentals arising under operating leases are recognized as an expense in the period in which they are incurred.

h. Borrowing cost

Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale.

Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. All other borrowing costs are recognized in profit or loss in the period in which they are incurred.

i. Investment in associates and joint ventures

An associated entity is an entity over which the Entity has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies.

A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control.

H-24

The results of associated companies and joint venture are incorporated in the consolidated financial statements using the equity method, unless the investment is classified as held for sale, in which case it is accounted for in accordance with IFRS 5.

Under the equity method, an investment in an associate or joint venture is initially recognized in the consolidated statement of financial position at cost and adjusted thereafter to recognize the Entity’s share of the profit or loss and other comprehensive income of the associate or joint venture. When the Entity’s share of losses of an associate exceeds the Entity’s interest in that associate (which includes any long-term interests that, in substance, form part of the Entity’s net investment in the associate), the Entity discontinues recognizing its share of further losses. Additional losses are recognized only to the extent that the Entity has incurred legal or constructive obligations or made payments on behalf of the associate or joint venture.

Any excess of the cost of acquisition over the Entity’s share of the net fair value of the identifiable assets, liabilities and contingent liabilities of an associate or joint venture recognized at the date of acquisition is recognized as goodwill, which is included within the carrying amount of the investment. Any excess of the Entity’s share of the net fair value of the identifiable assets, liabilities and contingent liabilities over the cost of acquisition, after reassessment, is recognized immediately in profit or loss.

The requirements of IAS 39 are applied to determine whether it is necessary to recognize any impairment loss with respect to the Entity’s investment in an associate or joint venture. When necessary, the entire carrying amount of the investment (including goodwill) is tested for impairment in accordance with IAS 36 Impairment of Assets (“IAS 36”) as a single asset by comparing its recoverable amount (higher of value in use and fair value less costs to sell) with its carrying amount. Any impairment loss recognized forms part of the carrying amount of the investment. Any reversal of that impairment loss is recognized in accordance with IAS 36 to the extent that the recoverable amount of the investment subsequently increases.

Upon disposal of an associate or joint venture that results in the Entity losing significant influence over that associate or joint venture, any retained investment is measured at fair value at that date and the fair value is regarded as its fair value on initial recognition as a financial asset in accordance with IAS 39. The difference between the previous carrying amount of the associate or joint venture attributable to the retained interest and its fair value is included in the determination of the gain or loss on disposal of the associate or joint venture. In addition, the Entity accounts for all amounts previously recognized in other comprehensive income in relation to that associate on the same basis as would be required if that associate had directly disposed of the related assets or liabilities. Therefore, if a gain or loss previously recognized in other comprehensive income by that associate or joint venture would be reclassified to profit or loss on the disposal of the related assets or liabilities, the Entity reclassifies the gain or loss from equity to profit or loss (as a reclassification adjustment) when it loses significant influence over that associate or joint venture.

When Entity transacts with its associate or joint venture, profits and losses resulting from the transactions with the associate or joint venture are recognized in the Entity’s consolidated financial statements only to the extent of interests in the associate or joint venture that are not related to the Entity.

j. Other current assets

Prepaid assets, included within other assets, mainly consist of costs related to uncompleted construction contracts, (mainly related to insurance and performance bonds) and software, which are recorded at historical cost and amortized over the estimated useful life of the asset, as applicable. Other assets also includes advances to subcontractors and suppliers as well as other prepaid expenses.

H-25

k. Impairment of long-lived assets

The Entity periodically evaluates the impairment of long-lived assets in order to determine whether there is evidence that those assets have suffered an impairment loss. If impairment indicators exist, the recoverable amount of assets is determined, with the help of independent experts, to determine the extent of the impairment loss, if any. When it is not possible to estimate the recoverable amount of an individual asset, the Entity estimates recoverable amount of the cash-generating unit to which the asset belongs. Where a reasonable and consistent basis of allocation can be identified, corporate assets are also allocated to individual cash-generating units, or otherwise they are allocated to the smallest group of cash-generating units for which a reasonable and consistent allocation basis can be identified.

Intangible assets with an indefinite useful life or not yet available for use are tested for impairment at least annually, and whenever there is an indication that the asset may be impaired.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognized immediately in profit or loss.

Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognized immediately in profit or loss.

l. Financial instruments

Financial assets and liabilities are recognized when the entity becomes a party to the contractual provisions of the instruments.

Financial assets and liabilities are initially measured at fair value. The transaction costs that are directly attributable to the acquisition or issue of a financial asset or liability different from financial assets and liabilities that are recognized at fair value through results are added or deducted from the fair value of assets and liabilities financial, initial recognition. Costs directly attributable to the acquisition of assets or financial liabilities recognized at fair value through profit or loss transaction are recognized immediately in the income statement.

Financial assets are classified into the following four categories, which in turn determine their form of valuation and kind of recognition: “Financial assets at fair value through profit or loss”, “preserved to maturity investments”, “financial assets available for sale “and” loans and receivables”. The classification depends on the nature and purpose of the administration at the time of initial recognition. The Entity generally only has financial assets at fair value through profit or loss, loans and accounts receivable.

In the statement of financial position, financial assets are classified as current and non-current depending on their maturity is less than / equal to or greater than 12 months

Financial assets at fair value through profit or loss

Financial assets are classified at fair value through profit or loss when the financial asset is held for trading or is designated as a financial asset at fair value through profit or loss. A financial asset is classified as held for trading if:

• It has been acquired principally for the purpose of selling it in the near term; or

H-26

• On initial recognition it is part of a portfolio of identified financial instruments that the Entity manages together and has a recent actual pattern of short-term profit-taking; or

• It is a derivative (except those designated as hedging instruments or that is a financial guarantee).

Financial assets at fair value through the results are recorded at fair value, recognizing any gain or loss arising from their remeasurement loss. The net gain or loss recognized in results includes any dividends or interest earned from financial asset and included in the valuation effect of financial instruments in the consolidated statements of comprehensive income. The fair value is determined as described in Note 22 f.

Loans and receivables

Loans and receivables are non-derivative financial assets, that have fixed or determinable payments that are not quoted in an active market. After initial recognition, loans and receivables are measured at amortized cost using the effective interest method.

“Amortized cost” means the initial amount recognized for a financial asset or liability less principal repayments, less (or plus) the cumulative amortization using the effective interest method of any difference between the initial amount and the amount at maturity, less any reduction (directly or through a reserve) for impairment or bad debt.

Impairment of financial assets

Financial assets other than financial assets at fair value through results are assessed for indicators of impairment at the end of each reporting period. Financial assets are considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of the investment have been affected.

Objective evidence of impairment of financial assets could include:

• Significant financial difficulty of the issuer or counterparty;

• Breach of contract, such as a default or delinquency in interest or principal payments; or

• It becoming probable that the borrower will enter bankruptcy or financial reorganization; or

• The disappearance of an active market for that financial asset because of financial difficulties.

The carrying amount of the financial asset is reduced directly by the impairment loss, except for trade receivables, where the carrying amount is reduced through the use of an allowance account. When a trade receivable is considered uncollectible, it is written off against the allowance account. Subsequent recoveries of amounts previously written off are recorded in results. Changes in the carrying amount of the allowance account are recognized in profit or loss.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss is reversed through results to the extent that the carrying amount of the investment at the date the impairment is reversed does not exceed the amortized cost if the impairment would not have been recognized.

Derecognition of financial assets

On partial or total derecognition of a financial asset in its entirety, the difference between the asset´s carrying amount and the sum of the consideration received and receivable and the cumulative gain or loss that had been recognized in other comprehensive income and accumulated in equity is recognized in results.

H-27

Financial liabilities

Financial liabilities are classified as financial liabilities at fair value through profit or loss, or other financial liabilities based on the substance of contractual arrangements.

Financial liabilities at fair value through profit or loss

Financial liabilities are classified at fair value through profit or loss when the financial liability is (i) contingent consideration that would be paid by the purchaser as part of a business combination to which IFRS 3 applies, (ii) held for trading, or (iii) it is designated at fair value through profit or loss.

A financial liability is classified as held for trading if:

• It has been acquired principally for the purpose of repurchasing it in the near term; or

• On initial recognition it is part of a portfolio of identified financial instruments that are managed together for which there is evidence of a recent pattern of making short-term profits, or

• It is a derivative that for accounting purposes does not comply with requirements to be designated as a hedging instrument.

A financial liability other than a financial liability held for trading or contingent consideration to be paid by the purchaser as part of a business combination may be designated as at fair value through profit or loss upon initial recognition, if:

• Such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise; or

• The financial liability forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair value basis, in accordance with the Entity’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or

• It forms part of a contract containing one or more embedded derivatives, and IAS 39 permits the entire combined contract (asset or liability) to be designated as at fair value through profit or loss.

Financial liabilities at fair value through profit or loss are stated at fair value, with any gains or losses arising on measurement recognized in profit or loss. The net gain or loss recognized in results incorporates any interest paid on the financial liability and is included in the effects of valuation of derivative financial instruments line item in the statement income and other comprehensive income.

Other financial liabilities

Other financial liabilities, including loans, bond issuances and debt with lenders and trade creditors and other payables are valued initially at fair value, represented generally by the consideration transferred, net of transaction costs, and are subsequently measured at amortized cost using the effective interest method.

Derecognition of financial liabilities

The Entity derecognizes financial liabilities when, and only when, the obligations are discharged, cancelled or they expire. The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable is recognized in results.

H-28

Effective interest rate method

The effective interest method is a method of calculating the amortized cost of a financial asset or liability and of allocating interest income or cost over the relevant period. The effective interest rate is the rate that exactly discounts future cash receivable or payable (including all fees and points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the financial instrument, or (where appropriate) a shorter period, to the carrying amount of the financial asset or liability on its initial recognition. When calculating the effective interest rate, all cash flows must be estimated (for example, prepayment, call options “call” and the like) except for future credit losses. The calculation must include all commissions and payments or receipts between the parties to the financial instrument, including other premiums or discounts.

Offsetting of financial assets and liabilities

Offsetting of financial assets and liabilities in the consolidated statement of financial position only occurs for accounts receivable and payable arising in transactions that contractually, or by law, have established a right of setoff and for which the Entity has the intention to pay a net amount or to realize the asset and pay the liability simultaneously.

m. Risk management policy

The Entity is exposed to risks that are managed through the implementation of systems related to identification, measurement, limitation of concentration, mitigation and supervision of such risks. The basic principles defined by Entity in the establishment of its risk management policy are the following:

• Compliance with the Corporate Governance Standards

• Establishment, by each different business line and subsidiaries, of risk management controls necessary to ensure that market transactions are conducted in accordance with the policies, rules and procedures of the Entity.

• Special attention to the financial risk management, basically composed by interest rate, the exchange rate, liquidity and credit risks (see Note 22).

Risk management in the Entity is mainly preventive and oriented to the medium and long term, taking into consideration the most probable scenarios of evolution of the variables affecting each risk.

n. Derivative financial instruments

The Entity underwrites a variety of financial instruments to manage its exposure to the risks of volatility in interest rates and exchange rates, including foreign currency forward contracts, interest rate swaps and cross currency swaps related to financing its construction projects. Note 19 includes a more detailed explanation of derivative financial instruments.

Derivatives are initially recognized at fair value at the date the derivative contract is entered into and are subsequently remeasured at fair value at the end of each reporting period. Fair value is determined based on recognized market prices. When the derivative is not listed on a market, fair value is based on valuation techniques accepted in the financial sector. Valuations are conducted quarterly in order to review the changes and impacts on the consolidated results.

The resulting gain or loss from remeasurement to fair value is recognized in profit or loss unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship.

A derivative with a positive fair value is recognized as a financial asset; a derivative with a negative fair value is recognized as a financial liability. A derivative is presented as a non-current asset or a non-current liability if the remaining maturity of the instrument is greater than 12 months and it is not expected to be realized or settled within 12 months. Other derivatives are presented as current assets or current liabilities.

H-29

Hedge accounting

At the inception of the hedge relationship, the Entity documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Entity documents whether the hedging instrument is highly effective in offsetting changes in fair values or cash flows of the hedged item.

When the related transaction fulfills all hedge accounting requirements, the derivative is designated as a hedging instrument when the contract is entered (either as a hedge of cash flow or hedge of foreign currencies or a fair value hedge). The decision to apply hedge accounting depends on economic or market conditions and economic expectations in the national or international markets. When the Entity contracts a derivative financial instrument for hedging purposes from an economic perspective but that instrument does not comply with all requirements established by IFRS to be considered as hedging instruments, gains or losses from such derivative financial instrument is applied to the results in the period in which it occurs.

The Entity’s policy is not to enter into derivative financial instruments for speculative purposes, but certain instruments entered into by the Entity that do not qualify as hedging instruments are accounted for as trading instruments and the fluctuation in fair value is recognized in the financial results of the period in which they are measured.

Effectiveness tests of derivatives that qualify as hedging instruments from an accounting perspective are performed at least once every quarter and every month, if there is a significant change.

Note 22 include details of the fair values of derivative instruments used for hedging purposes.

Fair value hedges

The change in the fair value of the hedging instruments and the change in the hedged item attributable to the hedged risk are recognized in the line item in the statement of income and other comprehensive income relating to the hedged item.

Cash flow hedges

For cash flow hedges (including interest rate swaps and interest rate options) and exchange rate hedges designated as cash flow hedges and foreign currency instruments including foreign exchange, currency swaps foreign and foreign currency options, the effective portion of changes in fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income. The ineffective portion is recognized immediately in the financial results of the period.

Amounts previously recognized in other comprehensive income and accumulated in equity are reclassified to results in the periods when the hedged item is recognized in results, in the same line item in the statement of income and other comprehensive income where the hedged item is recognized. However, when a forecasted transaction that is hedged gives rise to the recognition of a non-financial asset or a non-financial liability, the gains and losses previously accumulated in equity are transferred from equity and are included in the initial measurement of the cost of the non-financial asset or non-financial liability.

Interruption of hedge accounting

Hedge accounting is discontinued when the Entity revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or when it no longer qualifies for hedge accounting. Any accumulated gain or loss on the hedging instrument recognized in other comprehensive income remains there until the hedged item affects results. When a forecasted transaction is no longer expected to occur, the accumulated gain or loss is reclassified immediately to results.

H-30

Embedded derivatives

The Entity reviews all of its contracts to identify embedded derivatives that should be separated from the host contract for purposes of valuation and accounting. Derivatives embedded in other financial instruments or other host contracts are treated as separate derivatives when their risks and characteristics are not closely related to those of the host contracts and the host contracts are not measured at fair value through results.

The Entity has no significant effects arising from embedded derivatives at the end of the periods reported.

o. Provisions

Provisions are recognized when the Entity has a present obligation (legal or constructive) as a result of a past event, when it is probable that the Entity will be required to settle the obligation, and when a reliable estimate can be made of the amount of the obligation.

The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties associated with the obligation. When a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows.

The main provisions recognized by the Entity are for major maintenance, completion of construction and machinery leasing and related guarantees, and are classified as current or noncurrent based on the estimated time period to settle the obligation.

When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, a receivable is recognized as an asset if it is virtually certain that reimbursement will be received and the amount of the receivable can be measured reliably.

p. Income taxes

Income tax expense represents the sum of the tax currently payable and deferred tax. The tax currently payable is based on taxable profit for the year. Taxable profit differs from profit as reported in the consolidated statement of income and other comprehensive income because of items of income or expense that are taxable or deductible in periods different from when they are recognized in accounting profit or for items which are never taxable or deductible. Through December 31, 2013, the Business Flat Tax (“IETU”) was in effect, which was determined based on cash flows, considering the income received less the expenditures authorized by law. The income tax incurred was the higher of regular income tax (“ISR”) and IETU.

Deferred income taxes are recognized for the applicable temporary differences resulting from comparing the accounting and tax values of assets and liabilities plus any future benefits from tax loss carryforwards. Except as mentioned in the following paragraph, deferred tax liabilities are recognized for all taxable temporary differences and deferred tax assets are recognized for all deductible temporary differences and the expected benefit of tax losses. The carrying amount of deferred tax assets is reviewed at the end of each reporting period and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered.

Deferred tax liabilities are recognized for taxable temporary differences associated with investments in subsidiaries, except where the Entity is able to control the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax assets arising from deductible temporary differences associated with such investments and interests are only recognized to the extent that it is probable that there will be sufficient taxable profits against which to utilize the benefits of the temporary differences and they are expected to reverse in the foreseeable future.

H-31

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Entity expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

Current and deferred taxes are recognized as income or expense in profit or loss, except when it relates to items recognized outside of profit or loss, as in the case of other comprehensive income, stockholders’ equity items, or when the tax arises from the initial recognition of a business combination, in which case the tax is recognized in other comprehensive income as part of the equity item in question or, in the recognition of the business combination, respectively.

In addition, deferred tax liabilities are not recognized if the temporary difference arises from the initial recognition of goodwill.

Assets and deferred tax liabilities are offset when a legal right to offset assets with liabilities exists and when they relate to income taxes relating to the same tax authorities and the Entity intends to liquidate its assets and liabilities on a net basis.

q. Employee benefits

Retirement benefit costs and termination benefits

Payments to defined contribution retirement benefit plans are recognized as an expense when employees have rendered service entitling them to the contributions.

For defined benefit retirement benefit plans, the cost of providing benefits is determined using the projected unit credit method, with actuarial valuations being carried out at the end of each annual reporting period. Remeasurement, comprising actuarial gains and losses, the effect of the changes to the asset ceiling (if applicable) and the return on plan assets (excluding interest), is reflected immediately in the statement of financial position with a charge or credit recognized in other comprehensive income in the period in which they occur and will not be reclassified to profit or loss. Past service cost is recognized in profit or loss in the period of a plan amendment. Net interest is calculated by applying the discount rate at the beginning of the period to the net defined benefit liability or asset. Defined benefit costs are categorized as follows:

• Service cost (including current service cost, past service cost, as well as gains and losses on curtailments and settlements).

• Net interest expense or income.

• Remeasurement.

The Entity presents the first two components of defined benefit costs in profit or loss in the lines items construction cost and general expenses. Curtailment gains and losses are accounted for as past service costs.

The retirement benefit obligation recognized in the consolidated statement of financial position represents the actual deficit or surplus in the Entity’s defined benefit plans. Any surplus resulting from this calculation is limited to the present value of any economic benefits available in the form of refunds from the plans or reductions in future contributions to the plans.

A liability for a termination benefit is recognized at the earlier of when the entity can no longer withdraw the offer of the termination benefit and when the entity recognizes any related restructuring costs.

H-32

Short-term employee benefits

Liabilities recognized in connection with employee benefits in the short term are valued at undiscounted amount of the benefits expected to be paid in exchange for related services.

Certain subsidiaries are subject to statutory employee profit sharing (“PTU”), which is determined based on the Law on Income Tax (“ISR”), which is recorded in the results of the year in which it is incurred and presented under general expenses in the consolidated statements of income and other comprehensive income.

A liability is recognised for benefits accruing to employees in respect of wages and salaries, annual leave and sick leave in the period the related service is rendered at the undiscounted amount of the benefits expected to be paid in exchange for that service.

r. Revenue recognition

Revenues are recognized when it is likely that the Entity will receive the economic benefits associated with the transaction. Revenue is measured at the fair value of the consideration received or receivable and represents the amounts receivable for goods and services provided in the normal course of activities, Revenues are reduced for estimated customer returns, rebates and other similar allowances.

By type of activity, revenue is recognized based on the following criteria.

Construction Contracts

Revenues from construction contracts are recognized using the percentage-of-completion method based on the costs incurred method or the units of work method, considering total costs and revenues estimated at the end of the project, in accordance with IAS 11, Construction Contracts (“IAS 11”). The percentage-of-completion method provides an understanding of the performance of the project in a timely manner, and appropriately presents the legal and economic substance of the contracts. Under this method, revenue from the contract is compared against the costs incurred thereof, based on percentage-of-completion, which will determine the amount of revenue, expenses and income that can be attributed to the portion of work completed.

To use the percentage of completion method the following requirements must be met: (i) the contract must clearly specify legal rights relating to goods or services to be provided and received by the parties, the consideration to be paid and the terms of the agreement, (ii) the contract must specify the legal and economic right to receive payment for work performed while the contract progresses, (iii) it is expected that the contractor and the customer fulfill their contractual obligations, and (iv) that, based on the budget and the work contract, they can determine the total revenues, the total cost to be incurred and the estimated profit.

The base revenue utilized to calculate the amount of revenue to recognize as work progresses includes the following: (i) the initial amount established in the contract, (ii) additional work orders requested by the customer, (iii) changes in the considered yields, (iv) the value of any adjustments (for inflation, exchange rates or changes in prices, for example) agreed to in the contract, (v) the decrease in the original contract value and agreements in contracts, (vi) claims and conventional penalties, and (vii) completion or performance bonuses, as of the date on which any revision takes place and is effectively approved by the customers.

The basis for costs used to calculate the percentage of completion in accordance with the costs incurred method considers: (i) costs that relate directly to the specific contract, (ii) indirect costs related to contract activity and that can be identified with a specific contract, and (iii) any other costs that may affect the customer under the terms agreed in the contract. Costs that relate directly to a specific contract include all direct costs as raw material, labor, costs of subcontracting, manufacturing costs and supply of equipment carried out in independent workshops, project startup costs and depreciation. Indirect costs that are assignable to the contract include: indirect labor, administrative payroll, housing camps and related costs, quality control and inspection, internal and external oversight of the contract, insurance costs, bonds, depreciation, amortization, repair and maintenance.

H-33

The costs which are excluded are: (i) general administrative expenses that are not included under any form of reimbursement in the contract, (ii) selling expenses, (iii) the costs and expenses of research and development that have not been considered reimbursable by the contract, and (iv) depreciation of machinery and equipment not used in the specific contract even when available for a specific contract, if the contract does not allow revenue for such concept. Additionally, costs for work performed in independent workshops and construction in process are excluded until their receipt or use and are recorded as assets until such time.

Periodically, the Entity evaluates the reasonableness of the estimates used in determining the percentage of completion. Estimates of the costs of construction contracts are based on assumptions which may differ from the actual cost over the life of the project. The cost estimates are reviewed periodically, taking into account factors such as increases in the prices of materials, amount of work to be performed, inflation, exchange rate fluctuations, changes in contract specifications due to adverse conditions, provisions that are recorded in accordance with construction contracts throughout the duration of projects, including those relating to penalty clauses, completion and commissioning of the projects and the rejection of costs by customers, among others.

If, as a result of this evaluation, there are modifications to the revenue or cost previously estimated, adjustments are made for the percentage of completion and if there are indications that the estimated costs to be incurred to completion of the project will exceed the expected revenue, a provision is recognized for estimated contract loss in the period in which it is determined. Revenues and estimated costs may be affected by future events. Any changes in these estimates may affect the results of the Entity.

A variation on the extent of the work may be due to several factors, including: improvements in the construction process due to reduced supplies or runtime, local regulatory changes and changes in the conditions for the execution of the project or its implementation, design changes requested by the customer and the geological conditions not included in the original plan. Additionally, and in order to identify possible changes in contracts, the Entity has implemented a method by which these changes can be identified and reported, the amounts can be quantified and approved and the changes can be implemented efficiently on projects. A variation is included in contract revenue when: a) it is probable that the customer will approve the changes and the amount of revenue resulting from the change, b) the amount of revenue can be reliably measured and c) and it is probable that the economic benefits flow to the entity. Claims or incentives for early completion are recognized as part of the revenue of a contract, provided that there is sufficient evidence that the customer will authorize payment for these items. Consequently, claims and incentives are included in contract revenue only when: a) negotiations have reached an advanced stage such that it is probable that the customer will accept the claim, and b) the amount that probable to be accepted by the customer can be determined reliably. The costs incurred for change orders instructed by the client and are awaiting the definition and authorization of price, are recognized as an asset under the caption “Cost and Estimated Earnings in Excess of Billings on Uncompleted Contracts” described below. With respect to incentive payments, revenues are recognized only when the execution of the contract is significantly advanced to conclude that the specified standards of performance will be achieved or exceeded and the amount of the incentive payment can be measured reliably.

In projects financed by the Entity in which the value of the contract includes revenues from work execution and financing, only borrowing costs directly related to the acquisition or construction of assets, less any yield obtained by the temporary investment of such funds and the foreign exchange loss to the extent it is an adjustment to interest costs, are attributed to contract costs. Borrowing costs that exceed estimates and are not contractually reimbursed by customers are not part of the contract costs. In these types of contracts, the collection of the contract amount from the client may take place at the end of the project. However, periodic progress reports are presented to and approved by the customer, which form the basis for the Entity to obtain where appropriate, financing for the project in question.

H-34

When a contract includes the construction of several facilities, the construction of each is considered a separate profit center when: (i) separate proposals have been submitted for each facility, (ii) each facility has been subject to separate negotiations and the contractor and customer have been able to accept or reject that part of the contract relating to each asset, and (iii) revenue, costs and profit margin of each facility can be identified.

A group of contracts, whether with one or more customers, are managed as a single profit center if: (i) the group of contracts had been negotiated as a single package, (ii) the contracts are so closely interrelated that they are, in effect, part of a single project with an overall profit margin, and (iii) the contracts are performed simultaneously or in in a continuous sequence.

The Entity does not offset the profit and loss from separate profit centers. The Entity also ensures that when several contracts comprise a profit center, a combined result is presented.

Under the terms of various contracts, revenue recognized is not necessarily related to the amounts billable to customers. Management periodically assesses the reasonableness of its receivables. In cases where there are indications of difficulty of their recovery, estimates for doubtful accounts are recognized through results of the year they are determined. The estimate is based on the best judgment of the management under the circumstances prevailing at the time of determination, modified by changes in circumstances.

The line item “Cost and Estimated Earnings in Excess of Billings on Uncompleted Contracts” included in the heading of “Customers”, originates from construction contracts and represents the difference between the costs incurred plus recognized profit (or less any recognized losses) and less certifications made for all contracts in progress, in excess of the amount of the certificates of work performed and invoiced. Any amounts received before work has been performed are included in the consolidated statement of financial position as a liability, as advances from customers. Amounts invoiced from the performed work but not yet paid by the customer are included in the consolidated statement of financial position as trade and other receivables.

Interest income

Interest income is recorded on a periodic basis, with reference to capital and the effective interest rate applicable.

Leasing revenues

The Entity’s policy for recognition of revenue from operating leases is described in subsection f) on this note (the Entity as lessor).

5. Critical accounting judgments and key sources of estimation uncertainty

In the application of the Entity’s accounting policies, which are described in Note 4, the Entity’s management is required to make judgments, estimates and assumptions about the carrying amounts of assets and liabilities. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

Estimates and assumptions are reviewed regularly. Changes to accounting estimates are recognized in the period in which the change is made and future periods if the change affects both the current period and subsequent periods.

a. Critical judgments in applying accounting policies

The following are the critical judgments, apart from those involving estimations (see subsection b), performed by management throughout the process of applying the accounting policies of the Entity and that have the most significant effect on the amounts recognized in the consolidated financial statements.

H-35

• Assessment of the existence of control in subsidiaries, joint control or significant influence over investments in joint ventures (Note 14).

• The Entity’s defined benefit obligation is discounted at the rate set by reference to market yields at the end of the reporting period on government bonds. Significant judgment is required when setting the criteria for bonds to be included in the population from which the yield curve is derived (Note 28).

• The Entity is subject to transactions or contingent events over which professional judgment is exercised in developing estimates of probability of occurrence of probable outflows associated with adverse outcomes. The factors considered in these estimates are the legal merits of the case, as substantiated by the opinion of the Entity’s legal advisors.

b. Key sources of uncertainty in estimates

The following are the key assumptions concerning the future and other key sources of estimation uncertainty at the end of the reporting period that may have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year:

• Estimates of total construction contract revenues, costs and profits, according to the accounting for percentage of completion; and the determination of the responsibilities of the Entity relating to certain contingencies, including the result of pending work to be executed or future litigation, arbitration or other dispute resolution procedures relating to claims on contracts (Note 4r.)

• In order to estimate doubtful accounts receivable, among other elements, the Entity’s management considers the credit risk derived from the customer’s financial position and any significant collection delays based on the terms agreed in construction service agreements (Note 7).

• The Entity’s management reviews the estimated useful life and depreciation and amortization methods used for property, machinery and equipment at the end of each reporting. Based on detailed analysis the Entity’s management makes changes to the useful life of certain assets of property and equipment. The degree of uncertainty in estimates of useful lives is related to changes in the market and use of assets by production volumes and technological development (Note 11).

• Valuations for determining the recoverability of deferred tax assets and recoverable asset tax (Note 20).

• The Entity makes estimates to determine and recognize the provision for project completion, rental and maintenance of equipment, which is determined based on the degree of completion of projects and the hours of operation in the case of machinery (Note 17). To determine certain provisions, the Entity uses factors related to lead times for construction contracts and production volume, as well as hours of use for owned and leased machinery.

• The Entity values and recognizes derivatives at fair value, regardless of the purpose for holding them. Its bases fair value on market prices for derivatives traded in recognized markets. If no active market exists, the derivative instrument is valued using the valuations of counterparties (valuation agents) verified by a price provider authorized by the National Registry of Securities Comisión Nacional Bancaria y de Valores (“CNBV”). These valuations are based on methodologies recognized in the financial sector and are supported by sufficient and reliable information. Techniques and methods of valuation of derivative financial instruments are disclosed in Note 19.

Although these estimates were made based on the best information available at December 31, 2015, it is possible that events may take place in the future that will require their modification (increases or decreases) in subsequent years, which such modification would be made prospectively in the Entity’s consolidated financial statements.

Total customers	Ps.	11,562,821		Ps.	4,876,197

(1) Advance payments on work performed are applied against the receivable certificates as work on those projects is carried out.

Customers receivables are measured at amortized cost.

The Entity’s management considers that the carrying amount of accounts receivable represents its fair value. There is no interest charged on short-term accounts receivable from customers.

The management of accounts receivable and the determination of the need for a reserve are carried out at each project level that forms part of the consolidated financial statements, as each project has more thorough knowledge of the financial situation and relationship with each of its customers. However, certain guidelines do exist regarding specific characteristics that each customer must possess depending on the nature of the project. Generally, receivables from governmental entities do not possess recoverability issues.

With respect to private sector contracts, a maximum level of risk is assigned and collection conditions and terms are established based on the credit profile of the customer at the beginning of the customer relationship based on the magnitude of the specific project. For foreign private clients, the Entity’s policy is to generally require payments in advance at the start of the project and routine collections on a short-term basis to allow positive working capital management.

With respect to public contracts (mainly Pemex), the contracting entities define the payment through their established contract models, which provide for the payment of monthly amounts as well as payment in advance at the beginning of each of the periods during which the project will be executed.

H-37

Beginning in September 2015, Pemex entities restructured, such that “Pemex Refining” and “Pemex Gas and Basic Petrochemicals” merged into a single entity, “Pemex Transformation Industrial”; along with this restructuring, their payment period changed to 180 days.

b. Accounts receivable include amounts that are past due but not impaired at the end of the reporting period (see below the age analysis). The Entity does not hold any collateral or other credit enhancements over these balances, nor has the legal right to offset against any amount owed by the Entity to the counterpart. Aging of receivable balances that are past due but not impaired are as follows:

	December, 31
	2015		2014
Aged 61 to 120 days	Ps.	—	Ps.	9,143
Aged 120 to 360 days		12,801		557
Aged more than 360 days		2,724		8,127
Total	Ps.	15,525	Ps.	17,827
Average age (days)		285		217

According to the nature of the activities of the Entity, the industry in which it operates and the average credit conditions, the Entity has determined that the receivables aged greater than 60 days are considered past due. Detail of receivables that are aged greater than 60 days as of December 31, 2015 and 2014 are as follows:

	December 31, 2015						December 31, 2014

d. The cost and estimated earnings in excess of billings on uncompleted contracts is originated by construction contracts, and as is mentioned in Notes 5.b and 4. r represents the difference between the costs incurred plus recognized profits and / or less recognized losses and less certification amounts of work performed and billed on uncompleted contracts, as a result of applying the percentage of completion method of accounting for construction revenues. Requirements exist that must be met before billing of the cost and estimated earnings in excess of billings on uncompleted contracts, which are established in the billing terms defined in each of the contracts. Furthermore, the billings of change orders and claims are subject to the reconciliation of work, definition of the prices and the final resolution between the parties.

H-38

The Entity believes that the amounts of cost and estimated earnings in excess of billings on uncompleted contracts are current according to the status of projects, the documentation that supports the work performed, the progress of negotiations with the customer to reconcile balances for works such as additional works and contract changes, and the characteristics of its operation. Although costs and earnings in excess of billings may be outstanding for more than 365 days, based on the characteristics of the operation, the Entity believes that is able to collect within the normal course of operations under any of those contracts, given that most often times, they are outstanding as a result of contract changes and modifications, which are negotiated with and approved by the client. The amounts generally have to go through various reconciliation and administrative processes which may take more time than originally estimated. The Entity believes that its classification as current is appropriate. The Entity classifies these receivables as long-term only when collection is contractually agreed to be long-term or when the amounts are in a legal recovery process. Additionally, based on management estimates, the allowance for doubtful accounts of costs and estimated earnings in excess of billings on uncompleted contracts is sufficient.

As of December 31 2015 and 2014, the composition of the costs and estimated earnings in excess of billings on uncompleted contracts according to the date it was recorded, is as follows:

	December, 31
	2015		2014
0 to 90 days	Ps.	5,936,383	Ps.	2,417,576
From 91 to 360 days		4,239,959		1,820,149
More than 360 days		774,010		220,595
Total costs and estimated earnings in excess of billings on uncompleted contracts	Ps.	10,950,352	Ps.	4,458,320

e. Cost and estimated earnings in excess of billings on uncompleted contracts is composed as follows:

The provision related to costs expected to be incurred at the end of the project refers to costs that are originated under construction projects that the Entity anticipates it will incur through the time the projects are finished and ultimately paid for by the customer. Such amounts are determined systematically based on a percentage of the value of the work completed, over the performance of the contract, based on the experience gained from construction activity.

Due to the nature of the industry in which the Entity operates, projects are performed with individual specifications and guarantees, which require the Entity to create guarantee and contingency provisions that are continually reviewed and adjusted during the performance of the projects until they are finished, or even after termination. The increases, applications and cancellations shown in the previous table represent the changes derived from the aforementioned reviews and adjustments, as well as the adjustments for expiration of guarantees and contingencies.

The provision for litigation is recognized in accordance with the analysis of the related lawsuits or claims, according to opinions prepared by the legal advisers of the Entity. The Entity does not derecognize provisions until final resolutions are obtained and the payment process has begun, or there is no further doubt with respect to the associated risk.

Operating leases

a. Costs and expenses for operating leases

Operating leases are related to machinery and equipment with different lease terms, which range from 5 to 10 years. All operating lease contracts with terms greater than 5 years, contain a clause that stipulates a rental rate review at least every 5 years. The Entity does not have an option to purchase the leased assets end of the lease term.

Less than a year	Ps.	—	Ps.	3,897
Greater than 1 year and less than 5 years		—		—
Total	Ps.	—	Ps.	3,897

The income for operating leases for the years ended December 31, 2015, 2014 and 2013, amounted to Ps. 1,281, Ps. 8,226and Ps. 8,698, respectively.

19. Derivative financial instruments—Currency Forwards

Certain of the Entity’s construction contracts are denominated in U.S. dollars, while the related construction costs incurred are in Mexican pesos. In order to mitigate the risk of changes in the exchange rate of the U.S. dollar against the Mexican peso, forward currency contracts were entered into through which the exchange rate in which U.S. dollars will be received is fixed.

H-50

The risk of changes in the exchange rate to which the Entity is exposed because its monetary position is different from its functional currency is mitigated by contracting currency forwards through which the exchange results are compensated.

The forwards are “over the counter” entered into with financial institutions and designated as cash flow hedging instruments for a forecasted transaction (future revenue receivable in U.S. dollars) for which fluctuations in fair value are recognized in other comprehensive income in equity.

As of December 31, 2015 and 2014, the characteristics of current forward contracts are shown below:

20. Income taxes

The Entity is subject to ISR and through December 31, 2013, to IETU.

2014 Fiscal Reform

ISR - The rate was 30 % for the years 2015, 2014 and 2013, and under the new Income Tax Law enacted in 2014 (2014 Act), the rate will continue at 30% for 2016 and subsequent years. . The Entity incurred ISR on a consolidated basis with its subsidiaries through December 31, 2013.

In December 2013, Congress approved the Mexican Tax Reform with among other things, eliminated the flat tax (“IETU”) and the tax consolidation regime. As a result of the elimination of the IETU, for accounting purposes the Entity cancelled its existing deferred IETU recorded at the date of the Mexican Tax Reform.

IETU – Beginning in 2014, the flat tax was eliminated. Accordingly, the Entity was subject to, and recognized, IETU through December 31, 2013, which is a tax based on cash flows from both income and deductions and certain tax credits in each year. The rate was 17.5%. As a result of the elimination of the tax, the Entity canceled its existing deferred IETU balances through results of year and in its financial position.

Through December 31, 2013, income tax incurred was the higher of regular income tax (“ISR”) and IETU. Beginning January 1, 2014, income tax is solely ISR.

From 2008, the IMPAC Law was eliminated; however, in certain circumstances, recovery of IMPAC paid in the ten years immediately preceding that in which for first time ISR is paid is permitted, in the terms of the law.

21. Commitments and contingencies

a. Lawsuits and litigation - At December 31, 2015, the Entity was subject to labor legal proceedings and claims, against various Entity subsidiaries, which have their origin in the ordinary course of business. Management and legal advisers do not expect the Entity’s results of operations and financial condition as described in its consolidated financial statements will be materially impacted by the resolution of these matters.

b. Tax lawsuits - As of the date hereof, the Entity is in the process of settling several tax disputes before the relevant authorities. Given that these disputes relate to the return or recovery of taxes paid by the Entity before filing such claims, it does not expect to pay any additional amounts in the event it does not obtain favorable resolutions of such matters.

c. Performance guarantees. In the normal course of its operations, the Entity is required to guarantee its performance on its construction contracts, by means of letters of credit or bonds that guarantee compliance with its contracts or the quality of work performed. At December 31, 2015 the Entity has issued letters of credit in favor of its customers of U.S. $ 168,3626.

In addition at December 31, 2015, the Entity has also taken out bonds, mostly in favor of its customers, of Ps. 5,201,649, and U.S. $447,338.

Based on the nature of its activities, the Entity is exposed to different financial risks, mainly arising from the conduct of its ordinary business activities and its borrowings entered into to finance its operating activities. The Corporate Treasury function provides services to coordinate access to domestic and international financial markets, monitors and manages the financial risks relating to the operations of the Entity. The financial risks to which the Entity is subject are mainly: market risk (interest rates, currency exchange rates and prices), credit and liquidity risk.

H-57

Periodically, the Entity’s management assesses risk exposure and reviews the alternatives for managing those risks, seeking to minimize the effects of these risks using financial derivatives to hedge risk exposures. The Entity does not enter into derivatives for speculative purposes. The Board of Directors sets and monitors policies and procedures to measure and manage the risks to which the Entity is exposed, which are described below.

c. Market risk

The Entity is exposed to price risk, mainly for the following activities:

Construction contracts

The Entity generally executes two kinds of construction contracts with its customers: (i) fixed price (“either lump-sum or not-to exceed”) or (ii) profit margin over cost (“unit price”). The risks associated with inflation, exchange rates and the price increases of each contract type, whether executed with the public or private sector, are usually evaluated in a different manner.

In the case of private sector unit price contracts, the customer generally assumes risks involving inflation, exchange rates and the price increases of materials used for contract purposes. Under a unit-price contract, the signing of the contract, the parties agree the price for each unit of work. However, Unit price contracts normally contain escalation clauses whereby the Entity reserves the right to increase the unit price of certain inputs based on inflation, exchange rate variations or price increases whenever these risks increase over and above the percentage specified in the contract.

For unit price contracts related to public works, in addition to escalation clauses, in Mexico the “Public Works and Services Law” establishes mechanisms to adjust the value of such public unit-price contracts for cost increases. The Public Works and Services Law provides the following mechanisms for the adjustment of unit prices in unit-price contracts: (i) a review of individual unit prices for which adjustment may be possible; (ii) a review of unit prices by group, which multiplied by their corresponding amounts of work remaining to be performed, represent at least 80% of the total amount of remaining work under the contract, and (iii) for those projects in which the relationship between the input and the total contract cost is established, an adjustment to reflect the increased cost may be made based on such proportion. The application of these mechanisms is required to be specified in the relevant contract.

In lump-sum contracts, not-to exceed contracts or where there are no escalation clauses in which the Entity undertakes to provide materials or services at the unit prices required for a project in the private sector generally require it to absorb risks related to inflation, exchange rate fluctuations and materials price increases. However, these risks are mitigated in the following manner: (i) when preparing its bid, the Entity considers these risks to determine project costs and applies certain economic variables provided by firms of acknowledged reputation as regards economic analysis; (ii) certain contractual arrangements are made with the Entity’s main suppliers, including the payment of advances to ensure fixed materials prices throughout the duration of the contract; and (iii) the exchange rate risk is mitigated by executing contracts with suppliers and subcontractors in the same currency as that used for the customer contract. For those risks which cannot be mitigated or surpass acceptable levels, the Entity performs a quantitative analysis to determine the probability of each risk arising, measure its financial impact and adjust fixed contractual costs to an appropriate level.

For fixed price contracts in the public sector, the Public Works and Services Law protects the contractors when adverse economic conditions arise that could not have been anticipated at the time of awarding the contract and thus were not considered in the initial contract bid. The Public Works and Services Law allows the Controller’s Office (Secretaria de la Funcion Publica) to issue guidelines through which public works contractors may recognize increases in their initial contract prices as a result of adverse economic changes. The proposed application of these mechanisms for the public-to-private initiative is uncertain, but the proposed law would benefit the Public/Private Partnership (Proyecto para Prestación de Servicios, or PPS) by introducing options to renegotiate, in good faith, the contract terms in the event of government action to increase the project costs or otherwise reduce contractual benefits to developers.

H-58

In recent years, the construction contracts have been increasingly of the fixed price type or mixed price contracts in which a portion of the contract is at fixed price and the rest at unit prices. Even though, the Entity has entered into contracts with unit pricing in the last three years, it believes that fixed price contracts are more prevalent in the construction market and the contracts that the Entity enters into in the future will reflect this shift to fixed price contracts.

Interest rate risk management - This risk principally stems from changes in the future cash flows of debt entered into a variable interest rates (or with short-term maturity and presumable renewal) as a result of fluctuations in the market interest rates. The purpose of managing this risk is to lessen the impact in the cost of the debt due to fluctuations in such interest rates. To mitigate this risk, the Entity enters into financial derivatives which ensure fixed interest rates, establish maximum limits (ceilings) or narrow fluctuation bands for interest payments, relative to a substantial portion of any debt affected by such risk.

The risk is managed by the Entity maintaining an appropriate mix between fixed rate loans and variable rate, and the use of hedging contracts and interest rate futures contract interest rate. Hedging activities are evaluated regularly to align with interest rate risk and defined; ensuring that the most profitable coverage strategies are applied.

Given its debt position as of the reporting periods presented herein, management of the Entity does not consider that its interest rate risk is significant related to its financial position, operations and cash flows.

The administration of the Entity considers its interest rate risk is not significant in relation to its financial position, operations and flows.

Foreign exchange risk management - The Entity performs transactions denominated in foreign currency; consequently it is exposed to exchange rate risks which are managed within the parameters of approved policies. Accordingly, for this purpose, the Entity contracts exchange rate forwards whenever these instruments are considered to be effective. The main exchange rate risk is based on changes to the value of the Mexican peso against the U.S. dollar.

In fixed price, lump sum or guaranteed maximum price contracts, estimates are made to try and contemplate the risk of fluctuations in the exchange rate between the Mexican peso and other currencies in which the contracts are expressed, included the related financing agreements, or other contracts entered into for the purchase of supplies, machinery or raw materials, ordinary expenses and other inputs. A severe devaluation or appreciation of the Mexican peso could also result in an interruption in the international currency markets and could limit the ability to transfer or convert pesos to U.S. dollars and other currencies in order to make timely payments of interest and principal on the related obligations expressed in U.S. dollars or in other currencies. Although the Mexican government does not currently restrict, and has not restricted since 1982, the right or ability of Mexican individuals or business entities to convert pesos into U.S. dollars or other currencies, or to transfer them outside Mexico, the Mexican government could institute exchange control policies in the future. It cannot be guaranteed that the Banco de México will maintain its current policy regarding the peso. The fluctuation of the currency may have an adverse effect on the Entity’s financial position, results of operations and cash flows in future years.

For the year ended December 31, 2015, approximately 66% of consolidated revenues were expressed in foreign currencies, mainly U.S. dollars. An appreciation of the Mexican peso against the U.S. dollar would reduce the dollar denominated revenues when expressed in pesos, whereas a depreciation of the peso against the U.S. dollar would increase the dollar denominated revenues when expressed in pesos.

H-59

For the year ended December 31, 2015, 2014 and 2013, approximately 57%, 74% and 43%, respectively, of the construction backlog was denominated in foreign currencies, and approximately 43%, 31% and 21%, respectively, of accounts receivable were denominated in foreign currencies. At December 31, 2015, 2014 and 2013, approximately 66%, 61% and 40%, respectively, of consolidated financial assets were denominated in foreign currencies. Moreover, at December 31, 2015, 2014 and 2013, roughly 16%, 9% and 42%, respectively, of the debt was expressed in foreign currency. A depreciation in the value of the Mexican peso against the dollar will increase the peso value of costs, expenses and obligations denominated in U.S. dollars, unless they were denominated in the same currency as the source of payment. For the year ended at December 31, 2014, the Mexican peso had a 18% depreciation against the U.S. dollar compared to the exchange rates at the end of 2014.

Foreign currency sensitivity analysis - The following sensitivity analyses are based on an instantaneous and unfavorable change in exchange rates which affect the foreign currencies in which the Entity’s debt is expressed. These sensitivity analyses cover all the assets and liabilities denominated in foreign currency, as well as its derivative financial instruments. Sensitivity is determined by applying the hypothetical exchange rate change to its outstanding debt and making adjustments due to such fluctuations for the debt which is hedged by the financial derivatives.

As of December 31, 2015, a hypothetical, instantaneous and unfavorable change of 100 Mexican cents to the currency exchange rate applicable to the Entity’s debt, including derivative financial instruments only for hedging purposes, would have resulted in an estimated exchange loss of approximately Ps. 13 million.

The foreign currency position of the Entity is as follows:

	Liabilities				Assets
	December 31,				December 31,
Currency	2015		2014		2015		2014
U.S. dollars		385,618		341,759		372,022		266,242
Euros		2		66		1,459		208

The exchange rates prevailing at the date of the financial statements were as follows:

	December 31
	2015		2014
U.S. dollar exchange rate:
Interbank		Ps.17.3398		Ps.14.7348
Euro exchange rate		18.7873		17.9264

a. As of May 13, 2016, the issuance date of the 2015 financial statements, the interbank FIX rate was Ps. 17.9915.

d. Credit risk

Credit risk management - Credit risk refers to the risk whereby one of the parties defaults on its contractual obligations, thereby generating a financial loss for the Entity. To the extent possible, the objective of this risk management is to reduce its impact by reviewing the solvency of the Entity’s potential customers. Once contracts are underway, the credit rating of uncollected amounts is periodically evaluated and estimates are revised for allowance for doubtful accounts with corresponding entries to the statements of income and other comprehensive income in the period of the revision. The credit risk has historically been very limited.

H-60

The Entity’s maximum credit risk exposure is based on the table amounts detailed in the subsection b). Additionally, details of overdue, unimpaired accounts receivable are included in note 7.

The Entity has adopted the policy of only doing business with solvent parties and obtaining sufficient collateral when necessary, so as to mitigate the risk of financial losses derived from potential default. The Entity only performs transactions with entities with the best possible risk rating. The Entity’s credit exposure is reviewed and approved by senior management committees. The credit risk derived from cash, cash equivalents and derivative financial instruments is limited because counterparties are banks with high credit ratings assigned by credit bureaus. The financial instruments which potentially expose the Entity to credit risks are primarily composed by receivable certifications and uncertified work completion (generically known as “construction instruments”) and other accounts receivable.

Claims are occasionally filed against customers for additional project costs which exceed the contract price or for amounts which were not included in the original contract price, including modification orders. This type of claim is filed for issues such as delays attributable to the customer, higher unit prices or the modification of the initial project scope, thereby resulting in additional indirect or direct costs. These claims are often subject to long arbitration or legal processes or procedures involving external experts, meaning that it is difficult to accurately forecast when they will be definitively resolved. When this occurs and it has unresolved claims, the Entity can invest significant amounts of working capital in projects to cover excess costs while claims are resolved. Regarding particular modification orders, the Entity can reach an agreement with the customer regarding the work scope, albeit without determining the final price. In this case, the opinion of external experts may be required to appraise unfavorable prices determined outside the Entity’s control. As of December 31, 2015 and 2014 the Entity had an allowance for doubtful accounts of Ps. 0 and Ps. 3,937 related to commercial contracts and accounts receivable, respectively.

The credit risk on liquid funds and derivative financial instruments is limited because the counterparties are banks with high credit ratings assigned by recognized rating agencies. Other accounts receivable consist of amounts owed by debtors.

The Entity considers that these amounts do not result in significant concentrations of credit risk.

e. Liquidity risk

Liquidity risk management - This risk is generated by temporary differences between the funding required by the Entity to fulfill business investment commitments, debt maturities, current asset requirements, etc., and the origin of funds generated by the regular activities of the Entity, different types of bank financing and disinvestment. The objective of the Entity in the management of this risk is to maintain a balance between the flexibility, period and conditions of credit facilities contracted to manage short, medium and long-term funding requirements. The Executive Committee of the Entity is ultimately responsible for liquidity management. This Committee has established appropriate liquidity management guidelines. The Entity manages its liquidity risk by maintaining reserves, financial facilities and adequate loans, while constantly monitoring projected and actual cash flows and reconciling the maturity profiles of financial assets and liabilities.

H-61

The following table details the remaining contractual maturity of the Entity’s non-derivative financial liabilities, together with agreed repayment periods. This table has been prepared based on the projected non-discounted cash flows of financial assets and liabilities at the date on which the Entity must make payments. The table includes cash flows projected capital expenditures as financial debt included in the statement of financial position interests. To the extent that the interest is at variable rates, the undiscounted amount is derived from the curves in the interest rate at the end of the reporting period. Contractual maturity is based on the earliest date when the Entity must make the respective payment.

The Entity expects to meet its liabilities with its operational cash flows and resources received from the maturity of its financial assets. Furthermore, the Entity has access to revolving credit lines with different banking institutions.

f. Financial instruments at fair value

Some of the Entity’s financial assets and financial liabilities are measured at fair value at the end of each reporting period. The following table gives information about how the fair values of these financial assets and financial liabilities are determined (in particular, the valuation technique(s) and inputs used):

Financial assets and liabilities	Fair value at		Fair value hierarchy	Valuation models and key inputs	Significant unobservable inputs	Relation of unobservable inputs to fair value
	Diciembre 31,
	2015	2014
Foreign currency forward contracts (See Note 19)	Assets: Ps. 0 Liabilities: Ps. 134,192	Assets: Ps. 0 Liabilities: Ps. 6,645	Level 2	Future cash flows are calculated on the basis of exchange rates forward (from the types of observable change forward at the end of the reference period) and the rates of the forward contract, discounted at a rate reflecting the credit risk of various counterparties	NA	NA

During the period there were no transfers between Level 1 and 2.

The Entity considers carrying amount of all other financial assets and liabilities shown in financial statements approximate their fair value given their nature and short-term maturity.

23. Stockholders’ equity

a. Equity risk management

The objectives of the Entity with respect to management of its equity risk, are intended to maintain an optimum financial-net worth structure, to reduce capital costs and safeguard its capacity to continue its operations with solid indebtedness ratios.

H-62

The equity structure is essentially managed through the maintenance of adequate levels of Earnings before Interest, Taxes, Depreciation and Amortization (EBITDA), which is calculated in the following manner:

	For the year ended at December 31
	2015		2014		2013
Operating income	Ps.	2,041,120	Ps.	728,762	Ps.	390,879
Depreciation and amortization		147,126		139,785		110,565
Interest expense in cost of sales		28,177		31,554		24,531
EBITDA	Ps.	2,216,423	Ps.	900,101	Ps.	525,975

b. At December 31, 2015 and 2014 the share capital is variable, with a fixed minimum of Ps. 270 and is divided into two social parts (Series A and Series B). The series A represents 51% of the capital and can only be acquired by Mexican citizens. Series B represents 49% of the capital and subscription is free. As of December 31, 2015, 2014 and 2013 capital is as follows:

	Series		Amount		Amount
Partner	Class		2015		2014
Ingenieros Civiles Asociados, S.A. de C.V. (1)		“A”	Ps.	173,310	Ps.	479,310
Fluor Daniel México, S. A.		“B”		166,514		460,514
Historical value			Ps.	339,824	Ps.	939,824

(1) As mentioned in Note 1, the owner of the shares “A”, until December 2014, was CICASA.

c. At the stockholders’ ordinary general meeting in March 30, 2015, the stockholders approved an increase to the legal reserve for Ps21,772

d. At the stockholders’ ordinary general meeting in March 30, 2015, the stockholders declared dividends of Ps. 223,000, which have been fully paid.

e. At the stockholders’ extraordinary general meeting on November 3, 2015, the stockholders approve a reimbursement of capital of Ps. 600,000 of which Ps. 100,000 have been paid as of December 31, 2015 and 200,000 in January 2016, pending payment 300,000.

f. At the stockholders’ ordinary general meeting on April 21, 2014, the stockholders agreed to increase the legal reserve of Ps. 15,126.

g. At an extraordinary shareholders’ meeting held on December 17, 2013, the shareholders agreed to increase the variable capital of the Entity via a cash contribution of Ps. 600,000.

h. At the stockholders’ extraordinary general meeting on September 30, October 14 and December 2013 the stockholders declared dividends of Ps. 50,000, Ps. 600,000 and Ps. 300,000, respectively, which have been fully paid.

i. Stockholders’ equity, except restated paid-in capital and tax retained earnings will be subject to income tax at the rate in effect upon distribution. Any tax paid on such distribution may be credited against annual and estimated income tax of the year in which the tax on dividends is paid and the following two fiscal years, against the exercise tax and interim payments.

j. Retained earnings include the statutory legal reserve. The General Corporate Law requires that at least 5% of net income of the year be transferred to the legal reserve until the reserve equals 20% of capital stock at par value (historical pesos). The legal reserve may be capitalized but may not be distributed unless the entity is dissolved. The legal reserve must be replenished if it is reduced for any reason. At December 31, 2015 and 2014, the legal reserve is Ps. 94,863 and Ps. 73,091, respectively.

28. Employee benefits

The liability for employees derives from the pension plan, seniority premiums and payments at the end of employment to employees upon retirement, are determined based on actuarial computations made by external actuaries, using the projected unit credit method. Seniority premiums consist of a single payment equal to 12 day’s salary for each year of service based on the employee’s most recent salary, but without exceeding twice the current minimum wage established by law, and the pension plan consists of a single payment of 3 months salary plus 20 days per year worked based on the last salary.

H-66

The plans in Mexico typically expose the Entity to actuarial risks such as: investment risk, interest rate risk, longevity risk and salary risk.

Investment risk	The present value of the defined benefit plan liability is calculated using a discount rate determined by reference to long- term government bond yields, and if the return on the plan assets is below this rate, a deficit will be created in the plan. Currently the plan has a relatively balanced investment in variable income securities, debt instruments and real estate investments. Due to the long-term nature of the plan assets, the managing board of the pension fund considers it appropriate to invest a reasonable portion of the plan assets in variable income securities and in the real estate sector to maximize the fund’s profitability.
Interest rate risk	A decrease in the bond interest rate will increase the plan liability; however, this will be partially offset by an increase in the return on the plan’s debt investments.
Longevity risk	The present value of the defined benefit plan liability is calculated by reference to the best estimate of the mortality of plan participants both during and after their employment. An increase in the life expectancy of the plan participants will increase the plan’s liability.
Salary risk	The present value of the defined benefit plan liability is calculated by reference to the future salaries of plan participants. As such, an increase in the salary of the plan participants will increase the plan’s liability.

The most recent actuarial valuation of the defined benefit obligation were carried out at December 31, 2015 by Willis Towers Watson, which employs actuaries certified by the Colegio Nacional de Actuarios de Mexico. The present value of the defined benefit obligation, and the related current service cost and past service cost, were measured using the projected unit credit method.

The main assumptions used for the purposes of the actuarial valuations were as follows:

	December 31,
	2015			2014			2013
Discount for present value of labor benefits		7.00	%		6.75	%		7.00	%
Salaries increase		5.50	%		5.50	%		5.50	%

The amounts recognized in other comprehensive income in relation to these defined benefit plans are as follows:

Total	Ps.	62,565		Ps.	72,415	Ps.	49,179

The current service cost and the net interest expense for the year are included in the employee benefits expense in results. For the years ended December 31, 2015, 2014 and 2013 Ps. 54,471, Ps. 48,512 and Ps. 43,640 respectively, have been included in the consolidated income statement as cost of sales and administrative expenses.

The remeasurement of the net defined benefit liability is included in other comprehensive income. The following information shows a detail of the most significant plans of the Entity.

Amounts included in the consolidated statement of financial position arising from the entity’s obligation related to defined employees benefit are as follows:

	December 31,
	2015			2014			2013
Present value of funded defined benefit obligation	Ps.	(506,751	)	Ps.	(458,831	)	Ps.	(400,062	)

Changes in the present value of plan assets in the period:

	Year ended December 31,
	2015			2014			2013

Interest income		9,554			10,602			6,467
Re-measurement gain (loss):

Total plan assets at fair value	Ps.	143,836		Ps.	156,008		Ps.	164,692

As of December 31, 2015, 2014 and 2013 plan assets are invested in government securities.

The actuarial assumptions to determine the defined obligation are: the discount rate and the salary increase. The following sensibility analysis is determined based on reasonable changes that could occur at the end of the period, keeping constant all other variables:

• If the base discount rate increases 100 points, the obligation for defined benefit would be decrease by Ps. 38,523.

• If the base discount rate decreases 100 points, the obligation for defined benefit would increase by Ps. 44,527.

• If the salary rate were to increase by 1 %, the obligation for defined benefit would increase by Ps. 42,906.

• If the salary rate were to decrease by 1 %, the obligation for defined benefit would decrease Ps. 37,745.

The sensitivity analysis presented above may not be representative of the actual change in the defined benefit obligation as it is unlikely that the change in assumptions would occur in isolation of one another as some of the assumptions may be correlated.

Furthermore, in presenting the above sensitivity analysis, the present value of the defined benefit obligation has been calculated using the projected unit credit method at the end of the reporting period, which is the same as that applied in calculating the defined benefit obligation liability recognized in the statement of financial position.

There was no change in the methods and assumptions used in preparing the sensitivity analysis from prior years.

There was no change in the process followed by the Entity to manage its risks from prior periods.

The average duration of the benefit obligation as of December 31, 2015 and 2014 was 7.95 and 8.87 years respectively.

Defined contribution plans:

As part of the employee benefits, the Entity has defined contribution plans covering all employees under which the Entity contributes a maximum of 12.5% of each employee’s annual salary.

At December 2015, 2014 and 2013, the Entity has established a fund to which it contributes to cover the defined contribution plan which amounts to Ps. 45,224 and Ps. 47,082, and Ps. 39,494, and is invested in deposits financial institutions at market interest rate. The amount of contributions to the plan during the years ended December 31, 2015, 2014 and 2013 was Ps. 0 and Ps. 6,153 and Ps. 8,804, respectively.
