GULF ISLAND FABRICATION, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

FOR THE THREE - MONTH AND SIX - MONTH

PERIODS ENDED JUNE 30, 2013 AND 2012

NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Gulf Island Fabrication, Inc., together with its subsidiaries (the “Company”, “we” or “our”), is a leading fabricator of offshore drilling and production platforms and other specialized structures used in the development and production of offshore oil and gas reserves. The Company’s corporate offices and five major subsidiaries are located in Houma, Louisiana, and another major subsidiary is located in San Patricio County, Texas. The Company’s principal markets are concentrated in the offshore regions and along the coast of the Gulf of Mexico. The consolidated financial statements include the accounts of Gulf Island Fabrication, Inc. and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Gulf Island Fabrication, Inc. serves as a holding company and conducts all of its operations through its subsidiaries, including Gulf Island, L.L.C. (“Gulf Island”) and Gulf Marine Fabricators, L.P. (“Gulf Marine”) (both performing fabrication of offshore drilling and production platforms and other specialized structures used in the development and production of oil and gas reserves), Gulf Island Marine Fabricators, L.L.C. (“Gulf Island Marine”, performing marine fabrication and construction services), Dolphin Services, L.L.C. (“Dolphin Services”, performing offshore and onshore fabrication and construction services), Dolphin Steel Sales, L.L.C. (“Dolphin Steel Sales”, selling steel plate and other steel products) and Gulf Island Resources, L.L.C. (“Gulf Island Resources”, hiring of laborers with similar rates and terms as those provided by contract labor service companies).

Structures and equipment fabricated by us include: jackets and deck sections of fixed production platforms; hull, tendon, and/or deck sections of floating production platforms (such as “TLPs”, “SPARs”, “FPSOs” and “MinDOCs”); piles; wellhead protectors; subsea templates; various production, compressor and utility modules; offshore living quarters; towboats, offshore support vessels, dry docks, liftboats, tanks and barges. The Company also provides offshore interconnect pipe hook-up, inshore marine construction, manufacture and repair of pressure vessels, heavy lifts such as ship integration and TLP module integration, loading and offloading of jack-up drilling rigs, semi-submersible drilling rigs, TLPs, SPARs or other similar cargo, onshore and offshore scaffolding, piping insulation services, and steel warehousing and sales. For definitions of certain technical terms contained in this Form 10-Q, see the Glossary of Certain Technical Terms contained in our Annual Report on Form 10-K for the year ended December 31, 2012.

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information, the instructions to Form 10-Q, and Article 10 of Regulation S-X. Accordingly, the consolidated financial statements do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Cash flows from operating activities for prepaid subcontractor costs in the consolidated statement of cash flows for the six-months ended June 30, 2012 has been reclassfied to conform to the June 30, 2013 presentation. Operating results for the three-month and six-month periods ended June 30, 2013 are not necessarily indicative of the results that may be expected for the year ended December 31, 2013.

- 7 -

The balance sheet at December 31, 2012 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements.

For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

NOTE 2 – CONTRACTS RECEIVABLE AND RETAINAGE

The principal customers of the Company include major and large independent oil and gas companies and their contractors. Of our contracts receivable balance at June 30, 2013, $57.7 million, or 78.8%, is with four customers.

NOTE 3 – ASSETS HELD FOR SALE

On July 13, 2012, we received notice from our customer, Bluewater Industries (“Bluewater”), requesting (i) a slowdown of work on ATP Oil & Gas (UK) Limited’s (“ATP UK’s”) Cheviot project ordered pursuant to a master service contract between Bluewater and the Company (the “Contract”), and (ii) an amendment to the scheduled payment terms under the Contract. On August 16, 2012, we entered into a binding agreement (the “Agreement”) with Bluewater, an engineering consulting firm engaged by ATP UK to oversee the fabrication of the Cheviot project, to amend and restate the Contract and suspend the project. Among other things, the Agreement outlined revised payment terms for the contracts receivable balance. Specifically, Bluewater was required to pay $200,000 on or before the last day of each calendar month until February 28, 2013, with the remaining outstanding balance due on or before March 31, 2013. We recorded a $14.5 million reserve on the balance as of December 31, 2012. All installments under the Agreement were paid through February 28, 2013; however, the remaining balance of $30.9 million was not paid at March 31, 2013. We also entered into a separate agreement with Bluewater pursuant to which Bluewater granted us a security interest in certain of its equipment currently located on our facilities. As of April 1, 2013, the Agreement terminated and we initiated action to enforce our rights under the security agreement.

As a result of the termination of the agreement, the carrying amount of assets and liabilities relating to the project have been classified as held for sale in our consolidated balance sheet, resulting in a non-cash change in contract receivables, billings in excess of costs and estimated earnings on uncompleted contracts, and assets held for sale as of June 30, 2013.

Assets held for sale are required to be measured at the lower of its carrying amount or fair value less cost to sell. Management determined fair value with the assistance of third party valuation specialists, assuming the sale of the underlying assets individually or in the aggregate to a willing market participant, including normal ownership risks assumed by the purchaser, and the sale of certain components at scrap value. We estimated fair value relying on the cost approach primarily, while applying the market approach where comparable sales transaction information was readily available. The estimation of fair value under the cost approach is based on current replacement or reproduction costs of the asset less depreciation attributable to physical, functional, and economic factors. The market approach involves gathering data on sales and offerings of similar assets in order to value the subject assets. This approach also includes an assumption for the measurement of the loss in value from physical, functional, and economic factors inherent in the individual asset. The fair value of assets held for sale represent Level 3 fair value measurements (as defined by GAAP), based on the limited ability of market pricing information for either identical or similar items.

To date, we have not sold, licensed, or leased any of the equipment subject to the security agreement; however, we continue to actively market the equipment, and believe that the asset value is recoverable through the eventual disposition of project deliverables and the enforcement of our security interest. The ultimate recoverability of our investment in the assets is dependent upon various

- 8 -

factors such as market interest in the project deliverables and equipment, which may change in the future. These changes may lead to a revision in the recorded amount of assets held for sale and the amount ultimately recovered.

NOTE 4 – LINE OF CREDIT

Effective October 29, 2012, we entered into the Eleventh Amendment to the Ninth Amended and Restated Credit Agreement which, among other things, increased our revolving line of credit from $60 million to $80 million and extended the term of our revolver from December 31, 2013 to December 31, 2014. Our revolving line of credit is secured by substantially all of our assets. Amounts borrowed under our revolving line of credit bear interest, at our option, at either the prime lending rate established by JPMorgan Chase Bank, N.A. or LIBOR plus 1.5 percent. We pay a fee on a quarterly basis of one-fourth of one percent per annum on the weighted-average unused portion of our revolving line of credit.

At June 30, 2013, no amounts were outstanding under our revolving line of credit, and we had outstanding letters of credit totaling $48.7 million, which reduced the unused portion of our revolving line of credit to $31.3 million. We are required to maintain certain financial covenants, including a minimum current ratio of 1.25 to 1.0, a net worth minimum requirement of $244.8 million, debt to net worth ratio of 0.5 to 1.0, and earnings before interest, taxes, depreciation and amortization (EBITDA) to interest expense ratio of 4.0 to 1.0. As of June 30, 2013, we were in compliance with all covenants.

NOTE 5 – CONTRACT COSTS

We define material, freight, equipment rental and sub-contractor services included in the direct costs of revenue associated with projects as pass-through costs. Since we use the percentage-of-completion accounting method to recognize revenue on construction contracts under a direct labor efforts expended method, pass-through costs have little or no impact in the determination of gross margin for a particular period. Pass-through costs as a percentage of revenue were 53.1% and 42.1% for the three-month periods ended June 30, 2013 and 2012, respectively. Pass-through costs as a percentage of revenue were 54.7% and 39.1% for the six-month periods ended June 30, 2013 and 2012, respectively.

We recorded $35.0 million as of June 30, 2013 and $33.1 million as of December 31, 2012 of prepaid subcontractor costs. These costs primarily represent materials purchased using customer funds, but not installed on one of our major deepwater projects. These prepayments will be recognized as pass-through costs in future periods when installed.

At June 30, 2013, we recorded revenue totaling $1.7 million related to certain change orders on two projects which have been approved as to scope but not price. We expect to resolve these change orders in the third and fourth quarters of 2013. At June 30, 2012, we recorded revenue totaling $2.1 million related to certain change orders on two projects that had been approved as to scope but not price.

Report of Independent Registered

Public Accounting Firm

The Board of Directors and Shareholders

Gulf Island Fabrication, Inc.

We have reviewed the condensed consolidated balance sheet of Gulf Island Fabrication, Inc. as of June 30, 2013, and the related condensed consolidated statements of income and cash flows for the three-month and six-month periods ended June 30, 2013 and 2012, and condensed consolidated statement of changes in shareholders’ equity for the six-month period ended June 30, 2013. These financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures, and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the condensed consolidated interim financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Gulf Island Fabrication, Inc. as of December 31, 2012, and the related consolidated statements of income, changes in shareholders’ equity and cash flows for the year then ended (not presented herein) and in our report dated March 13, 2013, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2012, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Forward-Looking Statements

Statements under “Backlog,” “Results of Operations” and “Liquidity and Capital Resources” and other statements in this report and the exhibits hereto that are not statements of historical fact are forward-looking statements. These statements are subject to certain risks and uncertainties that could cause actual results and outcomes to differ materially from the results and outcomes predicted in the forward-looking statements and investors are cautioned not to place undue reliance upon such forward-looking statements. Important factors that may cause our actual results to differ materially from expectations or projections include those described in Item 1A. Risk Factors included in our Annual Report on Form 10-K for the year ended December 31, 2012 and Item 1A. Risk Factors contained in this Quarterly Report on Form 10-Q. Such factors include, among others, the cyclical nature of the oil and gas industry; the timing of new projects, including deepwater projects, and our ability to obtain them; our ability to attract and retain skilled employees at acceptable compensation rates; the dangers inherent in our operations and the limits on insurance coverage; and competitive factors in the marine fabrication and construction industry.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, which require us to make estimates and assumptions (see Note 1 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2012). We believe that our accounting policy on revenue recognition involves a high degree of judgment and complexity. Critical accounting policies are discussed more fully in our Annual Report on Form 10-K for the year ended December 31, 2012. There have been no changes in our evaluation of our critical accounting policies since December 31, 2012.

Backlog

Our backlog is based on management’s estimate of the direct labor hours required to complete, and the remaining revenue to be recognized with respect to those projects for which a customer has authorized us to begin work or purchase materials pursuant to written contracts, letters of intent or other forms of authorization. Often, however, management’s estimates are based on preliminary engineering and design specifications by the customer and are refined together with the customer. As engineering and design plans are finalized or changes to existing plans are made, management’s estimate of the direct labor hours required to complete a project and the price of a project at completion is likely to change. In addition, all projects currently included in our backlog generally are subject to suspension or termination at the option of the customer, although the customer is generally required to pay us for work performed and materials purchased through the date of termination and, in some instances, cancellation fees. In addition, customers have the ability to delay the execution of projects.

- 12 -

As of June 30, 2013, we had a revenue backlog of $433.8 million and a labor backlog of approximately 3.6 million man-hours remaining to work, including commitments received through July 17, 2013, compared to a revenue backlog of $537.0 million and a labor backlog of 4.4 million man-hours reported as of December 31, 2012, including commitments received through March 13, 2013.

Of our backlog at June 30, 2013,

• 70.7% was for three customers as compared to 66.5% for three customers at December 31, 2012.

• $358.7 million, or 82.7%, represented projects destined for deepwater locations compared to $393.3 million, or 73.2%, at December 31, 2012.

• $31.9 million, or 7.4%, represented projects destined for foreign locations compared to $41.9 million, or 7.8%, at December 31, 2012.

Depending on the size of the project, the termination or postponement of any one project could significantly reduce our backlog, and could have a material adverse effect on revenue, net income and cash flow.

As of June 30, 2013, we expect to recognize revenues from our backlog of approximately

• $267.4 million, or 61.6%, during the remaining six months of 2013,

• $124.6 million, or 28.7% during calendar year 2014, and

• $41.8 million, or 9.7% thereafter.

The timing of our recognition of the revenue backlog as presented above is based on management’s estimates of the application of the direct labor hours to complete the projects in our backlog. Certain factors and circumstances, as mentioned above, could cause changes in when we actually recognize revenue from our backlog as well as the ultimate amounts recorded.

Based on the activity of the major oil and gas companies and certain engineering companies, we expect bids for deepwater projects to be available in the second half of 2013 and into 2014. Bidding activity for marine related projects continues to remain steady.

Workforce

As of June 30, 2013, we had approximately 2,034 employees and approximately 548 contract employees, compared to approximately 2,180 employees and approximately 344 contract employees as of December 31, 2012.

Man-hours worked were 1.1 million during the three-month period ended June 30, 2013, compared to 1.3 million for the three-month period ended June 30, 2012. The major factor contributing to the decrease in man-hours worked for the three-month period ended June 30, 2013 was a higher utilization of subcontract work as compared to the three-month period ended June 30, 2012.

- 13 -

Man-hours worked were 2.1 million during the six-month period ended June 30, 2013, compared to 2.5 million for the six-month period ended June 30, 2012. The major factor contributing to the decrease in man-hours worked for the six-month period ended June 30, 2013 was the reduction in work requested to be performed on one of our larger deepwater projects and a higher utilization of subcontract work as compared to the six-month period ended June 30, 2012.

Results of Operations

Our revenue for the three-month periods ended June 30, 2013 and 2012 was $154.6 million and $137.2 million, respectively, an increase of 14.4%. Our revenue for the six-month periods ended June 30, 2013 and 2012 was $305.0 million and $250.3 million, respectively, an increase of 21.8%.

The increase in revenue for the three and six-month periods ended June 30, 2013 is primarily attributable to change orders that were approved during the quarter and included in contract revenue, and to a lesser degree an increase in pass-through costs for the respective periods. Pass-through costs as a percentage of revenue were 53.1% for the three-month period ended June 30, 2013, compared to 42.1% for the three-month period ended June 30, 2012. Pass-through costs as a percentage of revenue were 54.7% for the six-month period ended June 30, 2013, compared to 39.1% for the six-month period ended June 30, 2012. Pass-through costs were a significant portion of revenue for the three-month and six-month period ended June 30, 2013 due to the increased amounts of subcontractor services incurred for our two major deepwater projects. Pass-through costs, as described in Note 5 in the Notes to Consolidated Financial Statements, are included in revenue, but have generally little or no impact on our gross margin.

For the three-month periods ended June 30, 2013 and 2012, gross profit was $9.7 million (6.3% of revenue) and $13.9 million (10.1% of revenue), respectively. The decrease in gross profit was primarily due to losses of $11.0 million recognized during the three months ended June 30, 2013, associated with a large deepwater project, scheduled for delivery in the first quarter of 2014. To a lesser extent, gross profit was impacted by the higher level of pass-through costs for the three-month period ended June 30, 2013, relative to the comparable period in 2012. For the three months ended June 30, 2013, we recognized $82.1 million in revenue from pass-through costs, compared to $57.8 million for the three months ended June 30, 2012.

For the six-month periods ended June 30, 2013 and 2012, gross profit was $16.4 million (5.4% of revenue) and $26.6 million (10.6% of revenue), respectively. The decrease in gross profit was primarily due to losses associated with a large deepwater project, as described above, and to a lesser extent, the higher level of pass-through costs for the six-month period ended June 30, 2013, relative to the comparable period in 2012. For the six-months ended June 30, 2013, we recognized $166.9 million in revenue from pass-through costs, compared to $97.9 million for the six months ended June 30, 2012.

General and administrative expenses were $2.9 million and $5.2 million for the three-month and six-month periods ended June 30, 2013, respectively, compared to $2.6 million and $5.2 million for the three-month and six-month periods ended June 30, 2012, respectively. As a percentage of revenue, general and administrative expenses for the three-month and six-month periods ended June 30, 2013 were 1.8% and 1.7%, respectively, compared to 1.9% and 2.1% for the three-month and six-month periods ended June 30, 2012, respectively.

The Company had net interest expense of $60,000 and $123,000 for the three-month and six-month periods ended June 30, 2013, respectively, compared to net interest income of $157,000 and $309,000 for the three-month and six-month periods ended June 30, 2012, respectively. The increase in net interest expense for the three- and six-month periods ended June 30, 2013 was primarily related to the Company’s higher level of cash available for temporary investment for the comparable periods in 2012 relative to 2013. In addition, interest expense increased for the six-month period ended June 30, 2013 as a result of increased borrowings on the line of credit during the first six months of 2013.

The Company had $43,000 of other expense for the three-month and six-month periods ended June 30, 2013, compared to $22,000 and $85,000 in other income for the three-month and six-month periods ended June 30, 2012, respectively. Other income (expense) for the periods ended June 30, 2013 and 2012 primarily represents gains or losses on sales of property, plant, and equipment.

Our effective income tax rate for the three-month and six-month periods ended June 30, 2013 was 36.3% and 35.8%, respectively, compared to an effective tax rate of 34.0% for the comparable periods of 2012.

Liquidity and Capital Resources

Historically, we have funded our business activities through funds generated from operations. Effective October 29, 2012, we entered into the Eleventh Amendment to the Ninth Amended and Restated Credit Agreement which, among other things, increased our revolving line of credit from $60 million to $80 million and extended the term of our revolver from December 31, 2013 to December 31, 2014. Our revolving line of credit is secured by substantially all our assets. Amounts borrowed under our revolving line of credit bear interest, at our option, at the prime lending rate established by JPMorgan Chase Bank, N.A. or LIBOR plus 1.5 percent. We pay a fee on a quarterly basis of one-fourth of one percent per annum on the weighted-average unused portion of our revolver.

At July 30, 2013, no amounts were borrowed under our revolving line of credit, and we had outstanding letters of credit totaling $48.7 million, which reduced the unused portion of our revolver to $31.3 million. We are required to maintain certain financial covenants, including a minimum current ratio of 1.25 to 1.0, a minimum net worth requirement of $244.8 million, debt to net worth ratio of 0.5 to 1.0, and earnings before interest, taxes, depreciation and amortization (EBITDA) to interest expense ratio of 4.0 to 1.0. As of June 30, 2013, we were in compliance with all covenants. For information on the amount borrowed on the revolver at June 30, 2013 see Note 4 in the Notes to Consolidated Financial Statements.

At June 30, 2013, our cash and cash equivalents totaled $29.7 million, compared to $24.9 million at December 31, 2012. Working capital was $76.0 million and our ratio of current assets to current liabilities was 1.62 to 1.00 at June 30, 2013. Our primary use of cash during the period was related to capital expenditures. As of June 30, 2013, our investment in net contract position was $38.7 million compared to $43.3 million as of December 31, 2012, representing a decrease of $4.6 million, net of a non-cash

- 15 -

reclassification of $13.5 million to assets held for sale, as further described in Note 3 in the Notes to Consolidated Financial Statements. The change is due to timing of work performed on several larger contracts compared to scheduled contractual billing terms, and potential cost recoveries negotiated with customers. We define net contract position as contracts receivable, contract retainage, costs and estimated earnings in excess of billings on uncompleted contracts, materials and other amounts prepaid to subcontractors, accounts payable, accrued contract losses, and billings in excess of costs and estimated earnings on uncompleted contracts. An overall decrease in these contract related accounts represents a relative increase in cash on hand for working capital needs and a decrease in cash utilized by contracts in progress.

For the six-month period ended June 30, 2013, net cash provided by operating activities was $15.2 million compared to net cash used in operating activities of $4.2 million for the six-month period ended June 30, 2012. The overall increase in cash provided by operations for the six-month period ended June 30, 2013, compared to the six-month period ended June 30, 2012, is primarily due to the change in our net contract position, including the non-cash reclassification referred to above.

Net cash used in investing activities for the six-month period ended June 30, 2013 was $7.4 million, mainly related to capital expenditures for equipment and improvements to our production facilities, including an additional $1.1 million on ground preparation at our Texas facility and $1.2 million for dredging purposes for one of our projects at our Texas facility.

We anticipate additional capital expenditures for 2013 to be approximately $11.0 million for the purchase of equipment and additional yard and facility infrastructure improvements, including $5.8 of maintenance capital expenditures, $3.6 million for rolling equipment to replace aging rolling equipment at our Texas facility and $1.0 million for improvements to the graving dock at our Texas facility.

Net cash used in financing activities for the six-months ended June 30, 2013 and 2012 was $2.9 million, respectively.

We believe our cash and cash equivalents, generated by operating activities, reduction in our investment in net contract position, as previously discussed, and funds available under the revolver will be sufficient to fund our capital expenditures, and meet our working capital needs for the next twelve months. However, job awards may require us to issue additional letters of credit further reducing the capacity available on our revolving line of credit.

LINE OF CREDIT

NOTE 4 – LINE OF CREDIT

Effective October 29, 2012, we entered into the Eleventh Amendment to the Ninth Amended and Restated Credit Agreement which, among other things, increased our revolving line of credit from $60 million to $80 million and extended the term of our revolver from December 31, 2013 to December 31, 2014. Our revolving line of credit is secured by substantially all of our assets. Amounts borrowed under our revolving line of credit bear interest, at our option, at either the prime lending rate established by JPMorgan Chase Bank, N.A. or LIBOR plus 1.5 percent. We pay a fee on a quarterly basis of one-fourth of one percent per annum on the weighted-average unused portion of our revolving line of credit.

At June 30, 2013, no amounts were outstanding under our revolving line of credit, and we had outstanding letters of credit totaling $48.7 million, which reduced the unused portion of our revolving line of credit to $31.3 million. We are required to maintain certain financial covenants, including a minimum current ratio of 1.25 to 1.0, a net worth minimum requirement of $244.8 million, debt to net worth ratio of 0.5 to 1.0, and earnings before interest, taxes, depreciation and amortization (EBITDA) to interest expense ratio of 4.0 to 1.0. As of June 30, 2013, we were in compliance with all covenants.

CONTRACT COSTS

NOTE 5 – CONTRACT COSTS

We define material, freight, equipment rental and sub-contractor services included in the direct costs of revenue associated with projects as pass-through costs. Since we use the percentage-of-completion accounting method to recognize revenue on construction contracts under a direct labor efforts expended method, pass-through costs have little or no impact in the determination of gross margin for a particular period. Pass-through costs as a percentage of revenue were 53.1% and 42.1% for the three-month periods ended June 30, 2013 and 2012, respectively. Pass-through costs as a percentage of revenue were 54.7% and 39.1% for the six-month periods ended June 30, 2013 and 2012, respectively.

We recorded $35.0 million as of June 30, 2013 and $33.1 million as of December 31, 2012 of prepaid subcontractor costs. These costs primarily represent materials purchased using customer funds, but not installed on one of our major deepwater projects. These prepayments will be recognized as pass-through costs in future periods when installed.

At June 30, 2013, we recorded revenue totaling $1.7 million related to certain change orders on two projects which have been approved as to scope but not price. We expect to resolve these change orders in the third and fourth quarters of 2013. At June 30, 2012, we recorded revenue totaling $2.1 million related to certain change orders on two projects that had been approved as to scope but not price.

ASSETS HELD FOR SALE

NOTE 3 – ASSETS HELD FOR SALE

On July 13, 2012, we received notice from our customer, Bluewater Industries (“Bluewater”), requesting (i) a slowdown of work on ATP Oil & Gas (UK) Limited’s (“ATP UK’s”) Cheviot project ordered pursuant to a master service contract between Bluewater and the Company (the “Contract”), and (ii) an amendment to the scheduled payment terms under the Contract. On August 16, 2012, we entered into a binding agreement (the “Agreement”) with Bluewater, an engineering consulting firm engaged by ATP UK to oversee the fabrication of the Cheviot project, to amend and restate the Contract and suspend the project. Among other things, the Agreement outlined revised payment terms for the contracts receivable balance. Specifically, Bluewater was required to pay $200,000 on or before the last day of each calendar month until February 28, 2013, with the remaining outstanding balance due on or before March 31, 2013. We recorded a $14.5 million reserve on the balance as of December 31, 2012. All installments under the Agreement were paid through February 28, 2013; however, the remaining balance of $30.9 million was not paid at March 31, 2013. We also entered into a separate agreement with Bluewater pursuant to which Bluewater granted us a security interest in certain of its equipment currently located on our facilities. As of April 1, 2013, the Agreement terminated and we initiated action to enforce our rights under the security agreement.

As a result of the termination of the agreement, the carrying amount of assets and liabilities relating to the project have been classified as held for sale in our consolidated balance sheet, resulting in a non-cash change in contract receivables, billings in excess of costs and estimated earnings on uncompleted contracts, and assets held for sale as of June 30, 2013.

Assets held for sale are required to be measured at the lower of its carrying amount or fair value less cost to sell. Management determined fair value with the assistance of third party valuation specialists, assuming the sale of the underlying assets individually or in the aggregate to a willing market participant, including normal ownership risks assumed by the purchaser, and the sale of certain components at scrap value. We estimated fair value relying on the cost approach primarily, while applying the market approach where comparable sales transaction information was readily available. The estimation of fair value under the cost approach is based on current replacement or reproduction costs of the asset less depreciation attributable to physical, functional, and economic factors. The market approach involves gathering data on sales and offerings of similar assets in order to value the subject assets. This approach also includes an assumption for the measurement of the loss in value from physical, functional, and economic factors inherent in the individual asset. The fair value of assets held for sale represent Level 3 fair value measurements (as defined by GAAP), based on the limited ability of market pricing information for either identical or similar items.

To date, we have not sold, licensed, or leased any of the equipment subject to the security agreement; however, we continue to actively market the equipment, and believe that the asset value is recoverable through the eventual disposition of project deliverables and the enforcement of our security interest. The ultimate recoverability of our investment in the assets is dependent upon various factors such as market interest in the project deliverables and equipment, which may change in the future. These changes may lead to a revision in the recorded amount of assets held for sale and the amount ultimately recovered.
