AEGION CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.    GENERAL

The accompanying unaudited consolidated financial statements of Aegion Corporation and its subsidiaries (collectively, “Aegion” or the “Company”) reflect all adjustments (consisting only of normal recurring adjustments) that are, in the opinion of management, necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the dates and periods presented. Results for interim periods are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period. All significant intercompany related accounts and transactions have been eliminated in consolidation.

The Consolidated Balance Sheet as of December 31, 2018, which is derived from the audited consolidated financial statements, and the interim unaudited consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), the requirements of Form 10-Q and Article 10 of Regulation S-X and, consequently, do not include all information or footnotes required by GAAP for complete financial statements or all the disclosures normally made in an Annual Report on Form 10-K. Accordingly, the unaudited consolidated financial statements included herein should be read in conjunction with the audited consolidated financial statements and footnotes included in the Company’s 2018 Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 1, 2019.

Acquisitions/Strategic Initiatives/Divestitures

2017 Restructuring

On July 28, 2017, the Company’s board of directors approved a realignment and restructuring plan (the “2017 Restructuring”). As part of the 2017 Restructuring, the Company announced plans to: (i) divest the Company’s pipe coating and insulation businesses in Louisiana, The Bayou Companies, LLC and Bayou Wasco Insulation, LLC (collectively “Bayou”; (ii) exit all non-pipe related contract applications for the Tyfo^® system in North America; (iii) right-size the cathodic protection services operation in Canada and the CIPP businesses in Australia and Denmark; and (iv) reduce corporate and other operating costs.

During 2018, the Company’s board of directors approved additional actions with respect to the 2017 Restructuring, which included the decisions to: (i) divest the Australia and Denmark CIPP businesses; (ii) take actions to further optimize operations within North America, including measures to reduce consolidated operating costs; and (iii) divest or otherwise exit multiple additional international businesses. See Note 4.

Infrastructure Solutions Segment (“Infrastructure Solutions”)

On May 14, 2018, the Company’s board of directors approved a plan to divest the Company’s CIPP business in Australia (“Insituform Australia”). While restructuring actions in Insituform Australia led to improvements in operating results, an assessment of the long-term fit within the Company’s portfolio led to the decision to divest the business. Accordingly, the Company has classified Insituform Australia’s assets and liabilities as held for sale on the Consolidated Balance Sheet at March 31, 2019 and December 31, 2018. See Note 5.

Corrosion Protection Segment (“Corrosion Protection”)

During the first quarter of 2019, the Company initiated plans to sell its interest in its cathodic protection materials manufacturing and production joint venture in Saudi Arabia, Corrpower International Limited (“Corrpower”) and its interest in its Titeliner^® and CIPP joint venture in South Africa, Aegion South Africa Proprietary Limited (“Aegion South Africa”). Accordingly, the Company has classified the assets and liabilities of both businesses as held for sale on the Consolidated Balance Sheet at March 31, 2019. See Note 5.

2.    ACCOUNTING POLICIES

On January 1, 2019, the Company adopted FASB ASC 842, Leases (“FASB ASC 842”). See Note 6 for further information. Other than the adoption of FASB ASC 842, there were no material changes in accounting policies from those disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

8

Accumulated Other Comprehensive Income (Loss)

As set forth below, the Company’s accumulated other comprehensive loss is comprised of three main components: (i) currency translation; (ii) derivatives; and (iii) gains and losses associated with the Company’s defined benefit plan in the United Kingdom (in thousands):

	March 31,   2019			December 31, 2018
Currency translation adjustments	$	(39,158	)	$	(41,107	)
Derivative hedging activity	(431		)	1,715
Pension activity	(919		)	(898		)
Total accumulated other comprehensive loss	$	(40,508	)	$	(40,290	)

For the Company’s international subsidiaries, the local currency is generally the functional currency. Assets and liabilities of these subsidiaries are translated into U.S. dollars using rates in effect at the balance sheet date while revenues and expenses are translated into U.S. dollars using average exchange rates. The cumulative translation adjustment resulting from changes in exchange rates are included in the Consolidated Balance Sheets as a component of “Accumulated other comprehensive loss” in total stockholders’ equity. Net foreign exchange transaction losses of $0.8 million and $0.3 million in the first quarters of 2019 and 2018, respectively, are included in “Other expense” in the Consolidated Statements of Operations.

Taxation

The Company provides for estimated income taxes payable or refundable on current year income tax returns as well as the estimated future tax effects attributable to temporary differences and carryforwards, based upon enacted tax laws and tax rates, and in accordance with FASB ASC 740, Income Taxes (“FASB ASC 740”). FASB ASC 740 also requires that a valuation allowance be recorded against any deferred tax assets that are not likely to be realized in the future. The determination is based on the Company’s ability to generate future taxable income and, at times, is dependent on its ability to implement strategic tax initiatives to ensure full utilization of recorded deferred tax assets. Should the Company not be able to implement the necessary tax strategies, it may need to record valuation allowances for certain deferred tax assets, including those related to foreign income tax benefits. Significant management judgment is required in determining the provision for income taxes, deferred tax assets and liabilities and any valuation allowances recorded against net deferred tax assets.

Earnings per Share

Earnings per share have been calculated using the following share information:

	Quarters Ended   March 31,
	2019	2018
Weighted average number of common shares used for basic EPS	31,704,923	32,483,963
Effect of dilutive stock options and restricted and deferred stock unit awards	—	—
Weighted average number of common shares and dilutive potential common stock used for dilutive EPS	31,704,923	32,483,963

The Company excluded 549,679 restricted and deferred stock units for the quarter ended March 31, 2019, and 710,173 restricted and deferred stock units and stock options for the quarter ended March 31, 2018 from the diluted earnings per share calculation for the Company’s common stock because of the reported net loss for the periods.

Cash, Cash Equivalents and Restricted Cash

The Company classifies highly liquid investments with original maturities of 90 days or less as cash equivalents. Recorded book values are reasonable estimates of fair value for cash and cash equivalents.

Cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheets and Consolidated Statements of Cash Flows are as follows (in thousands):

Balance sheet data	March 31,   2019		December 31,   2018
Cash and cash equivalents	$	62,482	$	83,527
Restricted cash	1,235		1,359
Cash, cash equivalents and restricted cash	$	63,717	$	84,886

9

Restricted cash held in escrow primarily relates to funds reserved for legal requirements, deposits made in lieu of retention on specific projects performed for municipalities and state agencies, or advance customer payments and compensating balances for bank undertakings in Europe. Restricted cash related to operations is similar to retainage, and is, therefore, classified as a current asset, consistent with the Company’s policy on retainage.

Investments in Variable Interest Entities

The Company evaluates all transactions and relationships with variable interest entities (“VIE”) to determine whether the Company is the primary beneficiary of the entities in accordance with FASB ASC 810, Consolidation. There were no changes in the Company’s VIEs during the quarter ended March 31, 2019.

Financial data for consolidated variable interest entities are summarized in the following tables (in thousands):

Balance sheet data	March 31,   2019(1)		December 31,   2018
Current assets	$	29,847	$	33,066

Newly Issued Accounting Pronouncements

In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement: Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for Level 1, Level 2 and Level 3 instruments in the fair value hierarchy. The guidance is effective for the Company’s fiscal year beginning January 1, 2020, including interim periods within that fiscal year. The adoption of this standard is not expected to have a material impact on its consolidated financial statements.

In February 2018, the FASB issued Accounting Standards Update No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits a company to reclassify the income tax effects of the Tax Cuts and Jobs Act on items within accumulated other comprehensive income to retained earnings. Companies may adopt the new guidance using one of two transition methods: (i) retrospective to each period (or periods) in which the income tax effects are recognized, or (ii) at the beginning of the period of adoption. The Company adopted this standard effective January 1, 2019 and elected not to reclassify the tax effects due to the immaterial impact on the Company’s consolidated financial statements.

In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Measurement of Credit Losses on Financial Instruments, which changes the way in which entities estimate and present credit losses for most financial assets, including accounts receivable. The guidance is effective for the Company’s fiscal year beginning January 1, 2020, including interim periods within that fiscal year. Early adoption is permitted, although the Company does not intend to do so. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842), which requires lessees to present right-of-use assets and lease liabilities on the balance sheet for all leases with lease terms longer than twelve months. The Company adopted this standard, effective January 1, 2019, using the adoption-date transition provision, which recognizes and measures leases existing at January 1, 2019 but without retrospective application. See Note 6.

10

3.    REVENUES

On January 1, 2018, the Company adopted FASB ASC 606 for all contracts that were not completed using the modified retrospective transition method. The Company recognized the cumulative effect of initially applying FASB ASC 606 as a net reduction to opening retained earnings of $0.3 million as of January 1, 2018 due to the cumulative impact of adopting FASB ASC 606, with the impact primarily related to royalty license fee revenues.

Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in FASB ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. For contracts in which construction, engineering and installation services are provided, there is generally a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. The bundle of goods and services represents the combined output for which the customer has contracted. For product sales contracts with multiple performance obligations where each product is distinct, the Company allocates the contract’s transaction price to each performance obligation using its best estimate of the standalone selling price of each distinct good in the contract. For royalty license agreements whereby intellectual property is transferred to the customer, there is a single performance obligation as the license is not separately identifiable from the other goods and services in the contract.

The Company’s performance obligations are satisfied over time as work progresses or at a point in time. Revenues from products and services transferred to customers over time accounted for 92.9% and 95.0% of revenues for the quarters ended March 31, 2019 and 2018, respectively. Revenues from construction, engineering and installation services are recognized over time using an input measure (e.g., costs incurred to date relative to total estimated costs at completion) to measure progress toward satisfying performance obligations. Incurred cost represents work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Contract costs include labor, material, overhead and, when appropriate, general and administrative expenses. Revenues from maintenance contracts are structured such that the Company has the right to consideration from a customer in an amount that corresponds directly with the performance completed to date. Therefore, the Company utilizes the practical expedient in FASB ASC 606-55-255, which allows the Company to recognize revenue in the amount to which it has the right to invoice. Applying this practical expedient, the Company is not required to disclose the transaction price allocated to remaining performance obligations under these agreements. Revenues from royalty license arrangements are recognized either at contract inception when the license is transferred or when the royalty has been earned, depending on whether the contract contains fixed consideration. Revenues from stand-alone product sales are recognized at a point in time, when control of the product is transferred to the customer. Revenues from these types of contracts accounted for 7.1% and 5.0% of revenues for the quarters ended March 31, 2019 and 2018, respectively.

On March 31, 2019, the Company had $474.5 million of remaining performance obligations from construction, engineering and installation services. The Company estimates that approximately $445.1 million, or 93.8%, of the remaining performance obligations at March 31, 2019 will be realized as revenues in the next 12 months.

Contract Estimates

Accounting for long-term contracts involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, the Company estimates the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract, and recognizes that profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that sometimes span multiple years. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; the performance of subcontractors; and the availability and timing of funding from the customer.

The Company’s contracts do not typically contain variable consideration or other provisions that increase or decrease the transaction price. In rare situations where the transaction price is not fixed, the Company estimates variable consideration at the most likely amount to which it expects to be entitled. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. For royalty license agreements, the Company applies the sales-based and usage-based royalty exception and recognizes royalties at the later of: (i) when the subsequent sale or usage occurs; or (ii) the satisfaction or partial satisfaction of the performance obligation to which some or all of the sales-or usage-based royalty has been allocated. For contracts in which a portion of the transaction price is retained and paid after the good or service has been transferred to the customer, the Company does not recognize a significant financing component. The primary purpose of the retainage payment is often to provide the customer with assurance that the Company will perform its obligations under the contract, rather than to provide financing to the customer.

11

The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available.

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, contract assets and contract liabilities on the Consolidated Balance Sheets. Contract assets represent work performed that could not be billed either

12

due to contract stipulations or the required contractual documentation has not been finalized. Substantially all unbilled amounts are expected to be billed and collected within one year.

For fixed fee and time-and-materials based contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. For some royalty license arrangements, minimum amounts are billed over the license term as quarterly royalty amounts are determined. This results in contract assets as the Company recognizes revenue for the license when the license is transferred to the customer at contract inception. The Company’s contract liabilities consist of advance payments, billings in excess of revenue recognized and deferred revenue.

The Company’s contract assets and contract liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. Advance payments, billings in excess of revenue recognized and deferred revenue are each classified as current.

Net contract assets (liabilities) consisted of the following (in thousands):

	March 31,    2019(1)			December 31,   2018(2)
Contract assets – current	$	59,422		$	62,467
Contract liabilities – current	(27,060		)	(32,339		)
Net contract assets	$	32,362		$	30,128

__________________________

⁽¹⁾  Amounts exclude contract assets of $2.9 million and contract liabilities of less than $1.1 million that were classified as held for sale at March 31, 2019 (see Note 5).

⁽²⁾  Amounts exclude contract assets of $1.8 million and contract liabilities of less than $0.1 million that were classified as held for sale at December 31, 2018 (see Note 5).

Included in the change of total net contract assets was a $3.0 milliondecrease in contract assets, primarily related to the timing between work performed on open contracts and contractual billing terms, and a $5.3 milliondecrease in contract liabilities, primarily related to the timing of customer advances on certain contracts.

Substantially all of the $32.3 million and $51.6 million contract liabilities balances at December 31, 2018 and December 31, 2017, respectively, were recognized in revenues during the first quarters of 2019 and 2018, respectively.

Impairment losses recognized on receivables and contract assets were not material during the first quarters of 2019 and 2018.

4.    RESTRUCTURING

On July 28, 2017, the Company’s board of directors approved the 2017 Restructuring. As part of the 2017 Restructuring, the Company announced plans to: (i) divest Bayou; (ii) exit all non-pipe related contract applications for the Tyfo^® system in North America; (iii) right-size the cathodic protection services operation in Canada and the CIPP businesses in Australia and Denmark; and (iv) reduce corporate and other operating costs.

During 2018, the Company’s board of directors approved additional actions with respect to the 2017 Restructuring, which included the decisions to: (i) divest the Australia and Denmark CIPP businesses; (ii) take actions to further optimize operations within North America, including measures to reduce consolidated operating costs; and (iii) divest or otherwise exit multiple additional international businesses, including: (a) the Company’s cathodic protection installation activities in the Middle East, including Corrpower; (b) United Pipeline de Mexico S.A. de C.V., the Company’s Tite Liner^® joint venture in Mexico; (c) the Company’s Tite Liner^® businesses in Brazil and Argentina; (d) Aegion South Africa; and (e) the Company’s CIPP contract installation operations in England.

Total pre-tax 2017 Restructuring and related impairment charges since inception were $142.5 million ($128.5 million post-tax) and consisted of cash charges totaling $28.9 million and non-cash charges totaling $113.6 million. Cash charges included employee severance, retention, extension of benefits, employment assistance programs and other restructuring costs associated with the restructuring efforts described above. Non-cash charges included (i) $86.4 million related to goodwill and long-lived asset impairment charges recorded in 2017 as part of exiting the non-pipe FRP contracting market in North America, and (ii) $27.2 million related to allowances for accounts receivable, write-offs of inventory and long-lived assets, impairment of definite-lived intangible assets, as well as net losses on the disposal of both domestic and international entities. The Company reduced headcount by approximately 440 employees as a result of these actions.

13

The Company expects to incur additional cash and non-cash charges of $12 million to $16 million during 2019. The identified charges are primarily focused in the international operations of both Infrastructure Solutions and Corrosion Protection, but will also include certain charges in Energy Services to a lesser extent. The Company expects to reduce headcount by an additional 50 employees as a result of these further actions.

During the quarters ended March 31, 2019 and 2018, the Company recorded pre-tax expenses related to the 2017 Restructuring as follows (in thousands):

5.    ASSETS AND LIABILITIES HELD FOR SALE

During the first quarter of 2019, the Company initiated plans to sell its interests in Corrpower and Aegion South Africa. The Company is currently in discussions with third parties for each of the entities and believes that it is probable that sales of each entity will occur in the second half of 2019.

On May 14, 2018, the Company’s board of directors approved a plan to divest the assets and liabilities of Insituform Australia (see Note 1). The Company is currently in discussions with a third party and management believes that it is probable that a sale will occur in the first half of 2019.

The relevant asset and liability balances at March 31, 2019 and December 31, 2018 are accounted for as held for sale and measured at the lower of carrying value or fair value less cost to sell. No impairment charges were recorded on these assets as the net carrying value approximated or was less than management’s current expectation of fair value less cost to sell. In the event the Company is unable to sell the assets and liabilities or sells them at a price or on terms that are less favorable, or at a higher cost than currently anticipated, the Company could incur impairment charges or a loss on disposal.

6.    LEASES

Effective January 1, 2019, the Company adopted FASB ASC 842 using the adoption-date transition provision rather than at the earliest comparative period presented in the financial statements. Therefore, the Company recognized and measured leases existing at January 1, 2019 but without retrospective application. The Company also elected the package of practical expedients not to reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs and the lessee practical expedient to combine lease and non-lease components. The Company also made a policy election to not recognize right-of-use assets and lease liabilities for short-term leases for all asset classes. The impact of FASB ASC 842 on the Consolidated Balance Sheet beginning January 1, 2019 was through the recognition of operating lease assets and corresponding operating lease liabilities of $70.5 million. No impact was recorded to the Consolidated Statement of Operations or beginning retained earnings.

The Company’s operating lease portfolio includes operational field locations, administrative offices, equipment, vehicles and information technology equipment. The majority of the Company’s leases have remaining lease terms of 1 year to 20 years, some of which include options to extend the leases for 5 years or more. Right-of-use assets are presented within “Operating lease assets” on the Consolidated Balance Sheet. The current portion of operating lease liabilities are presented within “Accrued expenses”, and the non-current portion of operating lease liabilities are presented within “Operating lease liabilities” on the Consolidated Balance Sheet.

Operating lease assets and liabilities are recognized based on the present value of lease payments over the lease term at inception. For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating leases in effect prior to

16

January 1, 2019 were recognized at the present value of the remaining payments on the remaining lease term as of January 1, 2019. A portion of the Company’s real estate, equipment and vehicle leases is subject to periodic changes in the Consumer Price Index, LIBOR or other market index. The changes to these indexes are treated as variable lease payments and recognized in the period in which the obligation for those payments is incurred. Because most leases do not provide an explicit rate of return, the Company utilizes its incremental secured borrowing rate on a lease-by-lease basis in determining the present value of lease payments at the commencement date of the lease.

The following table presents the components of lease expense (in thousands):

	Quarter Ended March 31, 2019
Operating lease cost	$	5,452

In October 2015, the Company entered into an amended and restated $650.0 million senior secured credit facility with a syndicate of banks. In February 2018 and December 2018, the Company amended this facility (the “amended Credit Facility”). The amended Credit Facility consists of a $275.0 millionfive-year revolving line of credit and a $308.4 millionfive-year term loan facility, each with a maturity date in February 2023.

During the first quarter of 2018, the Company paid expenses of $2.4 million associated with the amended Credit Facility, $0.9 million related to up-front lending fees and $1.5 million related to third-party arranging fees and expenses, the latter of which was recorded in “Interest expense” in the Consolidated Statement of Operations. In addition, the Company had $2.4 million in unamortized loan costs associated with the original Credit Facility, of which $0.2 million was written off and recorded in “Interest expense” in the Consolidated Statement of Operations during the first quarter of 2018.

Generally, interest is charged on the principal amounts outstanding under the amended Credit Facility at the British Bankers Association LIBOR rate plus an applicable rate ranging from 1.25% to 2.25% depending on the Company’s consolidated leverage ratio. The Company can also opt for an interest rate equal to a base rate (as defined in the credit documents) plus an applicable rate, which also is based on the Company’s consolidated leverage ratio. The applicable LIBOR borrowing rate (LIBOR plus Company’s applicable rate) as of March 31, 2019 was approximately 4.49%.

The Company’s indebtedness at March 31, 2019 consisted of $275.6 million outstanding from the term loan under the amended Credit Facility and $44.0 million on the line of credit under the amended Credit Facility. Additionally, the Company had $0.9 million of debt held by its joint ventures (representing funds loaned by its joint venture partners) listed as held for sale at March 31, 2019 related to the planned sales of Corrpower and Aegion South Africa. During the first quarter of 2019, the Company borrowed $13.0 million on the line of credit for domestic working capital needs.

As of March 31, 2019, the Company had $22.6 million in letters of credit issued and outstanding under the amended Credit Facility. Of such amount, $12.3 million was collateral for the benefit of certain of our insurance carriers and $10.3 million was for letters of credit or bank guarantees of performance or payment obligations of foreign subsidiaries.

The Company’s indebtedness at December 31, 2018 consisted of $282.2 million outstanding from the term loan under the amended Credit Facility, $31.0 million on the line of credit under the amended Credit Facility and $1.0 million of third-party notes and bank debt.

At March 31, 2019 and December 31, 2018, the estimated fair value of the Company’s long-term debt was approximately $323.8 million and $307.7 million, respectively. Fair value was estimated using market rates for debt of similar risk and maturity and a discounted cash flow model, which are based on Level 3 inputs as defined in Note 13.

In October 2015, the Company entered into an interest rate swap agreement for a notional amount of $262.5 million, which is set to expire in October 2020. The notional amount of this swap mirrors the amortization of a $262.5 million portion of the Company’s $350.0 million term loan drawn from the original Credit Facility. The swap requires the Company to make a monthly fixed rate payment of 1.46% calculated on the amortizing $262.5 million notional amount, and provides for the Company to receive a payment based upon a variable monthly LIBOR interest rate calculated on the same amortizing $262.5 million notional amount. The receipt of the monthly LIBOR-based payment offsets a variable monthly LIBOR-based interest cost on a corresponding $262.5 million portion of the Company’s term loan from the original Credit Facility. After considering the impact of the interest rate swap agreement, the effective borrowing rate on the Company’s term note as of March 31, 2019 was approximately 3.74%. This interest rate swap is used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and is accounted for as a cash flow hedge. See Note 13.

On March 12, 2018, the Company entered into an interest rate swap forward agreement that begins in October 2020 and expires in February 2023 to coincide with the amortization period of the amended Credit Facility. The swap will require the

19

Company to make a monthly fixed rate payment of 2.937% calculated on the then amortizing $170.6 million notional amount, and provides for the Company to receive a payment based upon a variable monthly LIBOR interest rate calculated on the same amortizing $170.6 million notional amount. The receipt of the monthly LIBOR-based payment will offset the variable monthly LIBOR-based interest cost on a corresponding $170.6 million portion of the Company’s term loan from the amended Credit Facility. This interest rate swap will be used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and accounted for as a cash flow hedge. See Note 13.

The amended Credit Facility is subject to certain financial covenants, including a consolidated financial leverage ratio and consolidated fixed charge coverage ratio. Subject to the specifically defined terms and methods of calculation as set forth in the amended Credit Facility’s credit agreement, the financial covenant requirements, as of each quarterly reporting period end, are defined as follows:

• Consolidated financial leverage ratio compares consolidated funded indebtedness to amended Credit Facility defined income with a maximum amount not to exceed 3.75 to 1.00. At March 31, 2019, the Company’s consolidated financial leverage ratio was 3.23 to 1.00 and, using the amended Credit Facility defined income, the Company had the capacity to borrow up to $54.0 million of additional debt.

• Consolidated fixed charge coverage ratio compares amended Credit Facility defined income to amended Credit Facility defined fixed charges with a minimum permitted ratio of not less than 1.15 to 1.00. At March 31, 2019, the Company’s fixed charge ratio was 1.35 to 1.00.

At March 31, 2019, the Company was in compliance with all of its debt and financial covenants as required under the amended Credit Facility.

9.    STOCKHOLDERS’ EQUITY AND EQUITY COMPENSATION

Share Repurchase Plan

In December 2018, the Company’s board of directors authorized the open market repurchase of up to two million shares of the Company’s common stock. The program did not establish a time period in which the repurchases had to be made. In December 2018, the Company amended its Credit Facility, which limits the open market share repurchases to $32.0 million for 2019. Once repurchased, the Company promptly retires such shares.

The Company is also authorized to repurchase up to $10.0 million of the Company’s common stock in each calendar year in connection with the Company’s equity compensation programs for employees. The participants in the Company’s equity plans may surrender shares of common stock in satisfaction of tax obligations arising from the vesting of restricted stock, restricted stock unit awards and performance unit awards under such plans and in connection with the exercise of stock option awards. The deemed price paid is the closing price of the Company’s common stock on the Nasdaq Global Select Market on the date that the restricted stock, restricted stock unit or performance unit vests or the shares of the Company’s common stock are surrendered in exchange for stock option exercises. With regard to stock option awards, the option holder may elect a “net, net” exercise in connection with the exercise of employee stock options such that the option holder receives a number of shares equal to the built-in gain in the option shares divided by the market price of the Company’s common stock on the date of exercise, less a number of shares equal to the taxes due upon the exercise of the option divided by the market price of the Company’s common stock on the date of exercise. The shares of common stock surrendered for taxes due on the exercise of the option are deemed repurchased by the Company.

During the first quarter of 2019, the Company acquired 622,043 shares of the Company’s common stock for $11.1 million ($17.82 average price per share) through the open market repurchase program discussed above, 152,946 shares of the Company’s common stock for $3.1 million ($20.48 average price per share) in connection with the satisfaction of tax obligations in connection with the vesting of restricted stock units and performance units, and 48,409 shares of the Company’s common stock in connection with “net, net” exercises of employee stock options. Once repurchased, the Company immediately retired all such shares.

During the first quarter of 2018, the Company acquired 353,831 shares of the Company’s common stock for $8.4 million ($23.78 average price per share) through the open market repurchase program discussed above and 217,749 shares of the Company’s common stock for $5.3 million ($24.14 average price per share) in connection with the satisfaction of tax obligations in connection with the vesting of restricted stock, restricted stock units and performance units. Once repurchased, the Company immediately retired all such shares. The Company did not acquire any of the Company’s common stock in connection with “net, net” exercises of employee stock options.

20

Equity-Based Compensation Plans

In April 2016, the Company’s stockholders approved the 2016 Employee Equity Incentive Plan, which was amended in 2017 by the First Amendment to the 2016 Employee Equity Incentive Plan (as amended, the “2016 Employee Plan”). In April 2018, the Company’s stockholders approved the Second Amendment to the 2016 Employee Equity Incentive Plan, which increased by 1,700,000 the number of shares of the Company’s common stock reserved and available for issuance in connection with awards issued under the 2016 Employee Plan. The 2016 Employee Plan, which replaced the 2013 Employee Equity Incentive Plan, provides for equity-based compensation awards, including restricted shares of common stock, performance awards, stock options, stock units and stock appreciation rights. The 2016 Employee Plan is administered by the Compensation Committee of the board of directors, which determines eligibility, timing, pricing, amount and other terms or conditions of awards. As of March 31, 2019, 1,944,014 shares of the Company’s common stock were available for issuance under the 2016 Employee Plan.

In April 2016, the Company’s stockholders also approved the 2016 Non-Employee Director Equity Incentive Plan (the “2016 Director Plan”), which replaced the 2011 Non-Employee Director Equity Incentive Plan. The 2016 Director Plan provides for equity-based compensation awards, including non-qualified stock options and stock units. The board of directors administers the 2016 Director Plan and has the authority to establish, amend and rescind any rules and regulations related to the 2016 Director Plan. As of March 31, 2019, 68,689 shares of the Company’s common stock were available for issuance under the 2016 Director Plan.

Stock Awards

Stock awards, which include shares of restricted stock, restricted stock units and performance stock units, are awarded from time to time to executive officers and certain key employees of the Company. Stock award compensation is recorded based on the award date fair value and charged to expense ratably through the requisite service period. The forfeiture of unvested restricted stock, restricted stock units and performance stock units causes the reversal of all previous expense to be recorded as a reduction of current period expense.

A summary of the stock award activity is as follows:

	Quarter Ended    March 31, 2019
	Stock Awards		Weighted Average Award Date Fair Value
Outstanding at December 31, 2018	1,143,205		$	23.26
Restricted stock units awarded	283,472		20.24
Performance stock units awarded	146,367		22.78
Restricted stock units distributed	(171,073	)	18.21
Performance stock units distributed	(111,155	)	25.85
Restricted stock units forfeited	(6,655	)	23.13
Performance stock units forfeited	(42,939	)	25.90
Outstanding at March 31, 2019	1,241,222		$	22.88

Expense associated with stock awards was $2.0 million and $2.1 million for the quarters ended March 31, 2019 and 2018, respectively. Unrecognized pre-tax expense of $16.7 million related to stock awards is expected to be recognized over the weighted average remaining service period of 2.96 years for awards outstanding at March 31, 2019.

Deferred Stock Unit Awards

Deferred stock units are generally awarded to directors of the Company and represent the Company’s obligation to transfer one share of the Company’s common stock to the grantee at a future date. Historically, awards were fully vested, and fully expensed, on the date of grant. Beginning in April 2019, as a result of a recent amendment of the 2016 Director Plan, the expense related to the issuance of deferred stock units is based on the award date fair value and charged to expense ratably through the requisite service period, which is generally one year. The forfeiture of unvested deferred stock units causes the reversal of all previous expense to be recorded as a reduction of current period expense.

21

A summary of deferred stock unit activity is as follows:

	Quarter Ended    March 31, 2019
	Deferred Stock Units		Weighted Average Award Date Fair Value
Outstanding at December 31, 2018	287,350		$	22.80
Awarded	2,891		16.69
Distributed	(9,438	)	18.69
Outstanding at March 31, 2019	280,803		$	20.83

Expense associated with deferred stock unit awards was less than $0.1 million for each of the quarters ended March 31, 2019 and 2018.

Stock Options

Stock options on the Company’s common stock were awarded from time to time to executive officers and certain key employees of the Company. Stock options granted generally had a term of seven to ten years and an exercise price equal to the market value of the underlying common stock on the date of grant. There were 52,783 stock options exercised during the quarter ended March 31, 2019 with a weighted average exercise price of $18.11 per share. There were no stock options outstanding at March 31, 2019.

10.    TAXES ON INCOME

The Company’s effective tax rate in the quarter ended March 31, 2019 was a benefit of 16.0% on a pre-tax loss. The effective rate was negatively impacted by valuation allowances recorded on certain net operating losses in foreign jurisdictions for which no income tax benefits are expected to be recognized.

The Company’s effective tax rate in the quarter ended March 31, 2018 was a benefit of 40.4% on a pre-tax loss. The benefit was positively impacted by a $1.5 million net tax benefit, or 60.0% benefit to the effective tax rate, related to employee share-based payments vested during the first quarter of 2018. Excluding this benefit, the Company recorded income tax expense on a pre-tax loss primarily due to valuation allowances recorded on certain net operating losses in foreign jurisdictions for which no income tax benefits are expected to be recognized.

11.    COMMITMENTS AND CONTINGENCIES

Litigation

The Company is involved in certain litigation incidental to the conduct of its business and affairs. Management, after consultation with legal counsel, does not believe that the outcome of any such litigation, individually or in the aggregate, will have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows.

Purchase Commitments

The Company had no material purchase commitments at March 31, 2019.

Guarantees

The Company has many contracts that require the Company to indemnify the other party against loss from claims, including claims of patent or trademark infringement or other third-party claims for injuries, damages or losses. The Company has agreed to indemnify its surety against losses from third-party claims of subcontractors. The Company has not previously experienced material losses under these provisions and, while there can be no assurances, currently does not anticipate any future material adverse impact on its consolidated financial position, results of operations or cash flows.

The Company regularly reviews its exposure under all its engagements, including performance guarantees by contractual joint ventures and indemnification of its surety. As a result of the most recent review, the Company has determined that the risk of material loss is remote under these arrangements and has not recorded a liability for these risks at March 31, 2019 on its Consolidated Balance Sheet.

22

12.    SEGMENT REPORTING

The Company has three operating segments, which are also its reportable segments: Infrastructure Solutions; Corrosion Protection and Energy Services. The Company’s operating segments correspond to its management organizational structure. Each operating segment has a president who reports to the Company’s chief executive officer, who is also the chief operating decision manager (“CODM”). The operating results and financial information reported by each segment are evaluated separately, regularly reviewed and used by the CODM to evaluate segment performance, allocate resources and determine management incentive compensation.

The following disaggregated financial results have been prepared using a management approach that is consistent with the basis and manner with which management internally disaggregates financial information for the purpose of making internal operating decisions. The Company evaluates performance based on stand-alone operating income (loss), which includes acquisition and divestiture expenses and restructuring charges, if applicable.

During the first quarter of 2019, the Company began reporting Corporate expenses separately rather than allocating those costs to the operating segments. The reported information for the quarter ended March 31, 2018 has been revised to conform to the current period presentation.

Financial information by segment was as follows (in thousands):

13.    DERIVATIVE FINANCIAL INSTRUMENTS

As a matter of policy, the Company uses derivatives for risk management purposes, and does not use derivatives for speculative purposes. From time to time, the Company may enter into foreign currency forward contracts to hedge foreign currency cash flow transactions. For cash flow hedges, a gain or loss is recorded in the Consolidated Statements of Operations upon settlement of the hedge. All of the Company’s hedges that are designated as hedges for accounting purposes were highly effective; therefore, no notable amounts of hedge ineffectiveness were recorded in the Company’s Consolidated Statements of Operations for either the settlement of cash flow hedges or the outstanding hedged balance. At March 31, 2019, the Company’s cash flow hedges were in a net deferred loss position of $0.4 million compared to a net deferred gain position of $1.8 million at December 31, 2018. The change during the period was due to unfavorable movements in short-term interest rates relative to the hedged position. The Company presents derivative instruments in the consolidated financial statements on a gross basis. Deferred gains and losses were recorded in other non-current assets and other non-current liabilities, respectively, and other comprehensive income on the Consolidated Balance Sheets. The net periodic change of the Company’s cash flow hedges was recorded on the foreign currency translation adjustment and derivative transactions line of the Consolidated Statements of Equity.

The Company also engages in regular inter-company trade activities and receives royalty payments from certain of its wholly-owned entities, paid in local currency, rather than the Company’s functional currency, U.S. dollars. The Company utilizes foreign currency forward exchange contracts to mitigate the currency risk associated with the anticipated future payments from certain of its international entities. During the first three months of 2019 and 2018, a gain of $0.2 million and a loss of $0.1 million, respectively, were recorded upon settlement of foreign currency forward exchange contracts. Gains and losses of this nature are recorded to “Other income (expense)” in the Consolidated Statements of Operations.

In October 2015, the Company entered into an interest rate swap agreement for a notional amount of $262.5 million, which is set to expire in October 2020. The notional amount of this swap mirrored the amortization of a $262.5 million portion of the Company’s $350.0 million term loan drawn from the original Credit Facility. The swap requires the Company to make a monthly fixed rate payment of 1.46% calculated on the amortizing $262.5 million notional amount and provides for the Company to receive a payment based upon a variable monthly LIBOR interest rate calculated by amortizing the $262.5 million same notional amount. The receipt of the monthly LIBOR-based payment offsets a variable monthly LIBOR-based interest cost on a corresponding $262.5 million portion of the Company’s term loan from the original Credit Facility. This interest rate swap is used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and is accounted for as a cash flow hedge.

24

On March 12, 2018, the Company entered into an interest rate swap forward agreement that begins in October 2020 and expires in February 2023 to coincide with the amortization period of the amended Credit Facility. The swap will require the Company to make a monthly fixed rate payment of 2.937% calculated on the then amortizing $170.6 million notional amount, and provides for the Company to receive a payment based upon a variable monthly LIBOR interest rate calculated on the same amortizing $170.6 million notional amount. The receipt of the monthly LIBOR-based payment will offset the variable monthly LIBOR-based interest cost on a corresponding $170.6 million portion of the Company’s term loan from the amended Credit Facility. This interest rate swap will be used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and accounted for as a cash flow hedge.

The following table summarizes the Company’s derivative positions at March 31, 2019:

	Position	Notional Amount		Weighted Average Remaining Maturity In Years	Average Exchange Rate
USD/British Pound	Sell	£	3,552,000	0.3	1.31
EURO/British Pound	Sell	£	2,568,300	0.3	1.16
Interest Rate Swap		$	206,718,750	3.8

The following table provides a summary of the fair value amounts of our derivative instruments, all of which are Level 2 inputs as defined below (in thousands):

Designation of Derivatives	Balance Sheet Location	March 31,   2019			December 31,   2018
Derivatives Designated as Hedging Instruments:
Interest Rate Swaps	Other non-current assets	$	2,546		$	3,648
	Total Assets	$	2,546		$	3,648
Interest Rate Swaps	Other non-current liabilities	$	2,988		$	1,885

	Total Net Derivative Asset (Liability)	$	(525	)	$	1,719

FASB ASC 820, Fair Value Measurements (“FASB ASC 820”), defines fair value and establishes a framework for measuring and disclosing fair value instruments. The guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include:

• Level 1 – defined as quoted prices in active markets for identical instruments;

• Level 2 – defined as inputs other than quoted prices in active markets that are either directly or indirectly observable;

• Level 3 – defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

In accordance with FASB ASC 820, the Company determined that the value of all of its derivative instruments, which are measured at fair value on a recurring basis, are derived from significant observable inputs, referred to as Level 2 inputs.

25

The Company had no transfers between Level 1, 2 or 3 inputs during the quarter ended March 31, 2019. Certain financial instruments are required to be recorded at fair value. Changes in assumptions or estimation methods could affect the fair value estimates; however, the Company does not believe any such changes would have a material impact on its financial condition, results of operations or cash flows. Other financial instruments including cash and cash equivalents and short-term borrowings, including notes payable, are recorded at cost, which approximates fair value, which is based on Level 2 inputs as previously defined.

26

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

The following is management’s discussion and analysis of certain significant factors that have affected our financial condition, results of operations and cash flows during the periods included in the accompanying unaudited consolidated financial statements. This discussion should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2018.

We believe that certain accounting policies could potentially have a more significant impact on our consolidated financial statements, either because of the significance of the consolidated financial statements to which they relate or because they involve a higher degree of judgment and complexity. A summary of such critical accounting policies can be found in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of our Annual Report on Form 10-K for the year ended December 31, 2018 and in Note 2 to the consolidated financial statements contained in this report.

During the first quarter of 2019, we began reporting Corporate expenses separately rather than allocating those costs to the operating segments. The reported information for the quarter ended March 31, 2018 has been revised to conform to the current period presentation.

Our Long-Term Strategy

We are committed to being a valued partner to our customers, with a constant focus on expanding those relationships by solving complex infrastructure problems, enhancing our capabilities and improving execution while also developing or acquiring innovative technologies and comprehensive services. We are pursuing three key strategic initiatives:

Municipal Pipeline Rehabilitation – The fundamental driver in the global municipal pipeline rehabilitation market is the growing gap between the need and current spend. While we do not expect the spending gap to close any time soon, the increasing need for pipeline rehabilitation supports a long-term sustainable market for the technologies and services offered by our Infrastructure Solutions segment. We are committed to maintaining our market leadership position in the rehabilitation of wastewater pipelines in North America using our CIPP technology, the largest contributor to Aegion’s consolidated revenues. We have a diverse portfolio of trenchless technologies to rehabilitate aging and damaged municipal pipelines. The focus today is growing our presence in the rehabilitation of pressure pipelines through both internal development and acquisitions. Our pressure pipe portfolio includes Fusible PVC^®, InsituMain^® CIPP, Tyfo^® fiber-reinforce polymer (“FRP”) and Tite Liner^® high-density polyethylene (“HDPE”) systems. Our international strategy is to use a blend of third-party product sales as well as CIPP and FRP contract installation operations in select markets. A key to the success of this strategy is a continuing focus on improving productivity to reduce costs and increase efficiencies across the entire value chain from engineering, manufacturing and installation of our technology-based solutions.

Pipeline Integrity and Corrosion Management – There are over one million miles of regulated pipelines in North America, which remain the safest and most cost-effective mode of oil and gas transmission. Within our Corrosion Protection segment, the design and installation of cathodic protection systems to help prevent pipeline corrosion have historically represented a large portion of the revenues and profits for the segment. We also provide inspection services to monitor these systems and detect early signs of corrosion. In 2017, we launched a new asset integrity management program designed to increase the efficiency and accuracy of the pipeline corrosion assessment data we collect as well as upgrade how we share this valuable information with customers. Through this program, we seek to improve customer regulatory compliance and add new services in the areas of data gathering and validation, advanced analytics and predictive maintenance.

Downstream Oil Refining and Industrial Facility Maintenance – We have long-term relationships with oil refinery and industrial customers on the United States West Coast through our Energy Services segment. Our objective is to leverage those relationships to expand the services we provide in mechanical maintenance, electrical and instrumentation services, small capital construction, shutdown and turnaround maintenance activity and specialty services. We also continue to promote our safety and scaffolding services. There are opportunities in other industries on the West Coast such as oil and oil product terminals, chemicals, industrial gas and power to leverage our experience in maintenance and construction services. In addition, we are looking to expand our turnaround and specialty services beyond the West Coast.

Business Outlook

We believe a positive commercial outlook and the progress made over the last several years to simplify and position the Company in markets with favorable scale and earnings profiles will lead to modest earnings growth in 2019, despite a projected decline in consolidated revenues due to the lack of large project contributions during the year. Longer term, we believe our core businesses can generate annual revenue growth in the low to mid-single digit range, which should result in low double-digit annual earnings per share growth.

Infrastructure Solutions

One of the most attractive areas for growth is in the rehabilitation of municipal wastewater and pressure pipelines, primarily in North America. We offer a diverse portfolio of solutions in a highly fragmented and growing market. We made investments in 2018 to expand the use of Insituform^® CIPP in several regions currently underserved by Insituform in the North American wastewater pipeline market. Outside North America, we also have an attractive market in Asia-Pacific for large-diameter pressure pipe strengthening, and we are continuing to pursue a strategy of growing third-party product sales around the globe. Our objective is to maintain growth and our share in a large and mature market through a continued focus on productivity and offering customer-driven solutions through technological differentiation.

Over the last few years, we completed a research and development effort that significantly reduced material and installation costs for the Tyfo^® system while maintaining the superior material properties and quality of the technology. We also improved our InsituMain^® CIPP technology to give customers a more robust solution. In 2019, we are focused on two key technology initiatives to serve the pressure pipe and wastewater rehabilitation business. We are in final development and field testing for a robotic system to mechanically and effectively seal the service connection between a CIPP pressurized water main line to residential lines into homes. Success with this development initiative could address a weak point in current commercially available small-diameter pressure pipe rehabilitation systems today. We also recently introduced the application of ultraviolet light technology to cure felt CIPP tubes, which has the potential to reduce the environmental and equipment footprint that is currently required for the curing process. Any new technology takes time to penetrate the market, but we believe both initiatives represent long-term growth levers for the segment.

Corrosion Protection

Over 50 percent of Corrosion Protection’s revenues come from cathodic protection services for midstream oil and gas pipelines in North America, an attractive and growing market that we believe justifies further investment to outpace market growth. To that end, we continue to promote our new asset integrity management program for pipeline corrosion assessments. This new service improves data accuracy and processing efficiency, customizes the data transfer format (including geospatial mapping) and provides faster access to the information by customers. Corrosion Protection’s pipeline assessment services are expected to create a multiplier effect for our other capabilities in direct pipeline assessments, engineering, cathodic protection system installation and pipeline corrosion remediation. Our objective is to expand the relationships with our top customers, who are the leading pipeline owners in North America, to accelerate revenue growth.

With oil prices trading in a more stable range, we have seen improved demand for our Tite Liner^® lining pipeline protection system and our field pipe coatings applications, both in our North America market as well as overseas. We are focused on capturing additional opportunities in the Middle East, where we see a robust sales funnel over the next several years as national energy companies look to increase production through multiple major onshore and offshore gas and oil field development and expansion projects.

Energy Services

We expect Energy Services to continue to build on the momentum achieved in 2018. The outlook for day-to-day downstream refinery maintenance remains robust based on long-term contracts and our position as the lead outsourced provider of maintenance services at 14 out of the 17 refineries on the United States West Coast. We have an effort underway to expand our services to those customers in mechanical maintenance, turnaround service, electrical and instrumentation maintenance, scaffolding services and small capital construction activities.

Strategic Initiatives/Divestiture

2017 Restructuring

On July 28, 2017, our board of directors approved the 2017 Restructuring. As part of the 2017 Restructuring, we announced plans to: (i) divest our pipe coating and insulation businesses in Louisiana, The Bayou Companies, LLC and Bayou Wasco Insulation, LLC (collectively “Bayou”; (ii) exit all non-pipe related contract applications for the Tyfo^® system in North America; (iii) right-size the cathodic protection services operation in Canada and the CIPP businesses in Australia and Denmark; and (iv) reduce corporate and other operating costs.

During 2018, our board of directors approved additional actions with respect to the 2017 Restructuring, which included the decisions to: (i) divest the Australia and Denmark CIPP businesses; (ii) take actions to further optimize operations within North America, including measures to reduce consolidated operating costs; and (iii) divest or otherwise exit multiple additional international businesses, including: (a) our cathodic protection installation activities in the Middle East, including Corrpower International Limited, our cathodic protection materials manufacturing and production joint venture in Saudi Arabia; (b) United Pipeline de Mexico S.A. de C.V., our Tite Liner^® joint venture in Mexico; (c) our Tite Liner^® businesses in Brazil and Argentina; (d) Aegion South Africa Proprietary Limited, our Tite Liner^® and CIPP joint venture in the Republic of South Africa; and (e) our CIPP contract installation operations in England.

29

We divested our Bayou and Denmark CIPP businesses in 2018. Discussions are underway with a prospective buyer for the sale of the Australia CIPP business and we believe that it is probable that a sale will occur in the first half of 2019. During the first quarter of 2019, we also initiated plans to sell our cathodic protection joint venture in Saudi Arabia, Corrpower International Limited (“Corrpower”), and our Titeliner^® and CIPP joint venture in South Africa, Aegion South Africa Proprietary Limited (“Aegion South Africa”). We are currently in discussions with third parties for each of the entities and believe it is probable that sales will occur in the second half of 2019. Planned exits of the remaining international businesses noted above are expected to be substantially complete by June 30, 2019.

Total pre-tax 2017 Restructuring charges recorded during the first quarter of 2019 were $2.9 million ($2.6 million post-tax) and consisted of employee severance, retention, extension of benefits, employment assistance programs, early lease and contract termination and other restructuring costs associated with the restructuring efforts described above. Total pre-tax 2017 Restructuring and related impairment charges since inception were $142.5 million ($128.5 million post-tax), including cash charges of $28.9 million and non-cash charges of $113.6 million, of which $86.4 million relates to goodwill and long-lived asset impairment charges recorded in 2017 as part of exiting the non-pipe FRP contracting market in North America.

We expect to incur additional cash and non-cash charges of $12 million to $16 million during 2019. The identified charges are primarily focused in the international operations of both Infrastructure Solutions and Corrosion Protection, but will also include certain charges in Energy Services and Corporate to a lesser extent. We expect to reduce headcount by an additional 50 employees as a result of these further actions.

See Note 4 to the consolidated financial statements contained in this Report for a detailed discussion regarding our restructuring efforts.

Divestitures – Planned and Completed

Through our restructuring efforts to exit higher-risk, low return markets and streamline our operations, we have divested, or planned to divest, certain businesses in our Infrastructure Solutions and Corrosion Protection segments during 2019 and 2018:

i. During the first quarter of 2019, we entered into discussions with prospective buyers regarding the sale of our interests in Corrpower and Aegion South Africa. We currently believe it is probable that sales will occur in the second half of 2019.

ii. On November 1, 2018, we sold substantially all of the fixed assets and inventory from our CIPP operations in Denmark. In connection with the sale, we entered into a five-year exclusive tube-supply agreement whereby the buyers will exclusively purchase our Insituform^® CIPP liners. The buyers will also be entitled to use the Insituform^® trade name based on a trademark license granted for the same five-year time period.

iii. On August 31, 2018, we sold substantially all of the assets of Bayou and our ownership interest in Bayou Wasco Insulation LLC, which collectively had been held for sale as part of the 2017 Restructuring and reflected our desire to reduce further our exposure in the North American upstream oil and gas markets.

iv. On May 14, 2018, our board of directors approved plans to divest the assets and liabilities of our CIPP operations in Australia (“Insituform Australia”). While restructuring actions in Insituform Australia led to year-over-year improvements in operating results in 2018, an assessment of the long-term fit within Aegion’s portfolio led to the decision to divest the business. We are currently in discussions with a third party and, if those discussions are successful, we expect to close a transaction in the first half of 2019.

See Notes 1 and 5 to the consolidated financial statements contained in this Report for additional information.

Results of Operations – Quarters Ended March 31, 2019 and 2018

Significant Events

2017 Restructuring– As part of the 2017 Restructuring, we recorded pre-tax charges of $2.9 million ($2.6 million post-tax) and $5.2 million ($4.7 million post-tax) during the first quarter of 2019 and 2018, respectively. Restructuring charges primarily impacted the Infrastructure Solutions and Corrosion Protection reportable segments. See Note 4 to the consolidated financial statements contained in this Report.

Acquisition and Divestiture Expenses– We recorded pre-tax expenses of $0.1 million and $0.4 million during the first quarter of 2019 and 2018, respectively, related primarily to the planned divestitures of Insituform Australia, Corrpower and Aegion South Africa in 2019 and the Bayou divestiture and Hebna acquisition in 2018. Expenses primarily impacted the Corrosion Protection and Infrastructure Solutions reportable segments.

30

Warranty Reserve– During the first quarter of 2019, we recorded a pre-tax estimated project warranty reserve of $4.4 million ($3.3 million post-tax) related to a CIPP wastewater project in our North American operation of Infrastructure Solutions. The project was originally awarded in 2016 and construction was substantially completed during 2017. Recent inspections of the installed liners revealed structural failures due to extreme environmental conditions at the time of the installation. Replacement work will be performed during 2019 to remediate the warranty issues.

Revenues

Revenues decreased $48.0 million, or 14.8%, in the first quarter of 2019 compared to the first quarter of 2018. The decrease in revenues was due to a $33.6 milliondecrease in Corrosion Protection primarily from the sale of our pipe coating and insulation operation in 2018 and lower revenues in our Middle East coating services operation, a $11.5 milliondecrease in Energy Services due to a decrease in turnaround and construction services activities, and a $2.9 milliondecrease in Infrastructure Solutions primarily due to decreased international revenues from our CIPP contracting installation services operations as we exit or divest non-core operations as part of the 2017 Restructuring.

Gross Profit and Gross Profit Margin

Gross profit decreased $13.2 million, or 21.5%, in the first quarter of 2019 compared to the first quarter of 2018. During the first quarter of 2019, we recorded a $4.4 million charge for estimated project warranty costs in Infrastructure Solutions. Excluding this charge, gross profit decreased $8.7 million, or 14.2%, in the first quarter of 2019 compared to the first quarter of 2018. The decrease in gross profit was due to: (i) a $10.7 milliondecrease in Corrosion Protection primarily from lost gross profit related to our divested pipe coating and insulation operation and lower gross margins associated with our Middle East coating services operation as larger projects were completed in the prior year; and (ii) a $2.4 milliondecrease in Energy Services mainly due to a lower mix of higher-margin turnaround projects. Partially offsetting these decreases was a $4.3 millionincrease in Infrastructure Solutions primarily due to higher revenues and improved productivity related to CIPP contracting installation services activity in our North American operation and loss avoidance due to the divestiture of the Denmark CIPP operation in 2018.

Gross profit margin declined to 17.4% in the first quarter of 2019 from 18.9% in the first quarter of 2018. Excluding the project warranty charge noted above, gross profit margin improved 20 basis points to 19.1% in the first quarter of 2019. The improvement was primarily due to productivity improvements related to North American CIPP contracting installation services activity noted above and loss avoidance from Denmark. Partially offsetting the improvement in Infrastructure Solutions were decreases in Corrosion Protection from lower gross margins associated with our Middle East coating services operation and North American cathodic protection operations, and decreases in Energy Services from a lower mix of higher-margin turnaround projects.

Operating Expenses

Operating expenses decreased $8.3 million, or 14.7%, in the first quarter of 2019 compared to the first quarter of 2018. As part of our restructuring efforts, we recognized charges of $1.5 million and $3.5 million in the first quarters of 2019 and 2018, respectively. Excluding restructuring charges, operating expenses decreased $6.3 million, or 12.0%, in the first quarter of 2019 compared to the first quarter of 2018. The decrease in operating expenses was due to: (i) a $2.6 milliondecrease in Corrosion

31

Protection primarily due to our divested pipe coating and insulation operation and cost savings achieved in connection with our 2017 Restructuring actions; (ii) a $1.5 milliondecrease in Infrastructure Solutions primarily from exiting CIPP contracting installation services in certain international locations in Europe and Asia, and achieved cost savings in North America in connection with our 2017 Restructuring actions; and (iii) a $1.8 million decrease in Corporate expenses due to decreased spending and other cost-cutting measures as a result of the 2017 Restructuring, lower incentive compensation expense and lower medical and prescription drug expenses.

Operating expenses as a percentage of revenues were 17.3% in the first quarters of both 2019 and 2018. Excluding restructuring charges, operating expenses as a percentage of revenues were 16.7% in the first quarter of 2019 compared to 16.2% in the first quarter of 2018.

Consolidated Net Loss

Consolidated net loss was $4.0 million in the first quarter of 2019, an increase of $1.9 million from a loss of $2.1 million in the first quarter of 2018.

Included in consolidated net loss were the following pre-tax items: (i) restructuring charges of $2.9 million and $5.2 million in the first quarters of 2019 and 2018, respectively, related to employee severance, retention, extension of benefits, employee assistance programs, wind-down and other related restructuring costs; (ii) acquisition and divestiture expenses of $0.1 million and $0.4 million in the first quarters of 2019 and 2018, respectively; and (iii) a $4.4 million charge for estimated project warranty costs in Infrastructure Solutions in the first quarter of 2019.

Excluding the after-tax effect of the above items, consolidated net income was $2.0 million in the first quarter of 2019, a decrease of $2.2 million, or 52.9%, from $4.2 million in the first quarter of 2018. The decrease was primarily due to lower operating income in Corrosion Protection due to the divestiture of our pipe coating and insulation operation and lower contributions from the high-margin, large projects in our Middle East coating services operation. Partially offsetting the decrease in consolidated net income was an increase from Infrastructure Solutions related to higher revenues and profitability from our North American CIPP operation, loss avoidance from the Denmark sale in 2018 and improved execution of CIPP project activity in our Australian operation. Consolidated net income in the first quarter of 2019, as compared to the first quarter of 2018, was also positively impacted by lower non-controlling interest income, but negatively impacted by a higher tax rate due to certain discrete tax benefits recorded during the first quarter of 2018.

Contract Backlog

Contract backlog is our expectation of revenues to be generated from received, signed and uncompleted contracts, the cancellation of which is not anticipated at the time of reporting. We assume that these signed contracts are funded. For government or municipal contracts, our customers generally obtain funding through local budgets or pre-approved bond financing. We have not undertaken a process to verify funding status of these contracts and, therefore, cannot reasonably estimate what portion, if any, of our contracts in backlog have not been funded. However, we have little history of signed contracts being canceled due to the lack of funding. Contract backlog excludes any term contract amounts for which there are not specific and determinable work releases or values beyond a renewal date in the forward 12-month period. Projects whereby we have been advised that we are the low bidder, but have not formally been awarded the contract, are not included. Although backlog represents only those contracts and Master Service Agreements (“MSAs”) that are considered to be firm, there can be no assurance that cancellation or scope adjustments will not occur with respect to such contracts.

The following table sets forth our consolidated backlog by segment (in millions):

	March 31, 2019		December 31, 2018		March 31, 2018
Infrastructure Solutions (1)	$	305.2	$	323.3	$	349.2
Corrosion Protection (2)	130.7		127.9		155.6
Energy Services	218.4		218.2		215.6
Total backlog (3)	$	654.3	$	669.4	$	720.4

__________________________

⁽¹⁾  Included backlog from exited or to-be exited operations of $14.9 million, $10.0 million and $29.7 million at March 31, 2019, December 31, 2018 and March 31, 2018, respectively.

⁽²⁾  Included backlog from exited or to-be exited operations of $8.0 million, $11.6 million and $30.7 million at March 31, 2019, December 31, 2018 and March 31, 2018, respectively.

32

⁽³⁾  Total backlog for March 31, 2019, December 31, 2018 and March 31, 2018 included backlog from exited or to-be exited operations of $22.9 million, $21.6 million and $60.4 million, respectively.

Included within backlog for Energy Services are amounts that represent expected revenues to be realized under long-term MSAs and other signed contracts. If the remaining term of these arrangements exceeds 12 months, the unrecognized revenues attributable to such arrangements included in backlog are limited to only the next 12 months of expected revenues. Although backlog represents only those contracts and MSAs that are considered to be firm, there can be no assurance that cancellation or scope adjustments will not occur with respect to such contracts.

Within our Infrastructure Solutions and Corrosion Protection segments, certain contracts are performed through our variable interest entities, in which we own a controlling portion of the entity. As of March 31, 2019, 0.1% and 18.4% of our Infrastructure Solutions backlog and Corrosion Protection backlog, respectively, related to these variable interest entities. A substantial majority of our contracts in these two segments are fixed price contracts with individual private businesses and municipal and federal government entities across the world. Energy Services generally enters into cost reimbursable contracts that are based on costs incurred at agreed upon contractual rates.

Consolidated customer orders, net of cancellations (“New Orders”), decreased $88.0 million, or 24.9%, to $264.8 million in the first quarter of 2019 compared to $352.8 million in the first quarter of 2018.

Infrastructure Solutions Segment

“N/A” represents not applicable.

Revenues

Revenues decreased $2.9 million, or 2.1%, in the first quarter of 2019 compared to the first quarter of 2018. The decrease in revenues was primarily due to decreased international revenues from our CIPP contracting installation services operations as we exit or divest non-core operations as part of the 2017 Restructuring. Partially offsetting the decrease in revenues was an increase in CIPP contracting installation services activity in North America as a result of improved crew productivity following significant weather, labor and equipment challenges in the prior year.

Gross Profit and Gross Profit Margin

Gross profit decreased $0.1 million, or 0.5%, in the first quarter of 2019 compared to the first quarter of 2018. During the first quarter of 2019, we recorded a $4.4 million charge for estimated project warranty costs related to one CIPP contracting installation project in our North American operation. Excluding this charge, gross profit increased $4.3 million, or 16.0%, in the first quarter of 2019 compared to the first quarter of 2018. The increase in gross profit was primarily due to: (i) higher revenues and execution efficiencies related to CIPP contracting installation services activity in our North American operation; (ii) loss avoidance due to the divestiture of Denmark in 2018; and (iii) improved execution of CIPP project activity in our Australian operation.

Gross profit margin improved 30 basis points in the first quarter of 2019 compared to the first quarter of 2018 mainly due to the same factors that improved gross profit above.

33

Operating Expenses

Operating expenses decreased $2.1 million, or 9.3%, in the first quarter of 2019 compared to the first quarter of 2018. As part of our restructuring efforts, we recognized charges of $1.3 million and $1.9 million in the first quarters of 2019 and 2018, respectively. Excluding restructuring charges, operating expenses decreased $1.5 million, or 7.6%, in the first quarter of 2019 compared to the first quarter of 2018. The decrease in operating expenses was primarily due to exiting CIPP contracting installation services in certain international locations in Europe and Asia, and achieved cost savings in North America in connection with our 2017 Restructuring actions.

Operating expenses as a percentage of revenues were 15.2% in the first quarter of 2019 compared to 16.4% in the first quarter of 2018. Excluding restructuring charges, operating expenses as a percentage of revenues were 14.2% in the first quarter of 2019 compared to 15.1% in the first quarter of 2018.

Operating Income and Operating Margin

Operating income increased $2.5 million, or 76.6%, to $5.7 million in the first quarter of 2019 compared to $3.2 million in the first quarter of 2018. Operating margin improved to 4.3% in the first quarter of 2019 compared to 2.4% in the first quarter of 2018.

Included in operating income are the following items: (i) restructuring charges of $2.1 million and $3.2 million in the first quarters of 2019 and 2018, respectively, related to employee severance, retention, extension of benefits, employee assistance programs, wind-down and other related restructuring costs; (ii) acquisition and divestiture related expenses of $0.1 million and less than $0.1 million in the first quarters of 2019 and 2018, respectively; and (iii) a $4.4 million charge in the first quarter of 2019 for estimated project warranty costs related to one CIPP contracting installation project in our North American operation.

Excluding the above items, operating income increased $5.8 million, or 89.9%, to $12.3 million in the first quarter of 2019 compared to $6.5 million in the first quarter of 2018, and operating margin improved 450 basis points to 9.3% in the first quarter of 2019 compared to 4.8% in the first quarter of 2018. Operating income increased primarily due to higher revenues and profitability from our North American CIPP operation due to crew productivity improvement, loss avoidance due to the divestiture of Denmark in 2018 and improved execution of CIPP project activity in our Australian operation.

Corrosion Protection Segment

Key financial data for Corrosion Protection was as follows:

“N/A” represents not applicable.

Revenues

Revenues decreased $33.6 million, or 34.3%, in the first quarter of 2019 compared to the first quarter of 2018. The decrease was primarily due to: (i) an $11.6 million decrease in revenues related to our pipe coating and insulation operation, which was divested in the third quarter of 2018; (ii) decreased revenue from our coating services operation, which benefited in the first quarter of 2018 from large project activity in the Middle East; (iii) decreased project activities in our cathodic protection operations; and (iv) decreased international revenues from our industrial linings and cathodic protection operations as we exit or divest non-core operations as part of the 2017 Restructuring.

Gross Profit and Gross Profit Margin

Gross profit decreased $10.7 million, or 45.4%, and gross profit margin declined 400 basis points in the first quarter of 2019 compared to the first quarter of 2018. Gross profit decreased primarily due to: (i) a $3.1 million decrease in gross profit

34

related to our divested pipe coating and insulation operation; (ii) lower revenues and gross margins associated with our coating services operation, most notably in the Middle East, as larger projects were completed; and (iii) decreased gross profit from certain international industrial linings and cathodic protection operations as noted above. Gross profit and gross profit margin were also negatively impacted by our North American cathodic protection operations, which experienced lower revenues and project delays in Canada.

Operating Expenses

Operating expenses decreased $4.1 million, or 22.0%, in the first quarter of 2019 compared to the first quarter of 2018. As part of our restructuring efforts, we recognized charges of $0.1 million and $1.3 million in the first quarters of 2019 and 2018, respectively. Excluding restructuring charges, operating expenses decreased $2.6 million, or 15.5%, in the first quarter of 2019 compared to the first quarter of 2018. Operating expenses decreased primarily due to: (i) a $1.5 million decrease related to our divested pipe coating and insulation operation; (ii) cost savings achieved in connection with our 2017 Restructuring actions; and (iii) lower incentive compensation expense.

Operating expenses as a percentage of revenues were 22.3% in the first quarter of 2019 compared to 18.8% in the first quarter of 2018. Excluding restructuring charges, operating expenses as a percentage of revenues were 22.4% in the first quarter of 2019 compared to 17.4% in the first quarter of 2018. The increase, as a percentage of revenues, was primarily driven by the lower revenues generated from our coating services operation during the first quarter of 2019, as compared to the same period in 2018.

Operating Income (Loss) and Operating Margin

Operating income decreased $6.7 million, or 135.5%, to a loss of $1.8 million in the first quarter of 2019 compared to income of $5.0 million in the first quarter of 2018. Operating margin declined to (2.7)% in the first quarter of 2019 compared to 5.1% in the first quarter of 2018.

Included in operating income are (i) restructuring charges of $0.2 million and $1.5 million in the first quarters of 2019 and 2018, respectively, related to employee severance, retention, extension of benefits, employee assistance programs, wind-down and other related restructuring costs; and (ii) acquisition and divestiture related expenses of less than $0.1 million in each of the first quarters of 2019 and 2018.

Excluding restructuring charges and acquisition and divestiture expenses, operating income decreased $8.0 million to a loss of $1.5 million in the first quarter of 2019 compared to income of $6.5 million in the first quarter of 2018 and operating margin declined to (2.3)% in the first quarter of 2019 compared to 6.6% in the first quarter of 2018. The decreases in operating income and operating margin were primarily the result of: (i) decreased operating income related to our divested pipe coating and insulation operation; (ii) lower revenues and related gross profit generated from our coating service operation in the Middle East; and (iii) lower revenues and decreased project performance in our North American cathodic protection operations.

“N/A” represents not applicable.

Revenues

Revenues decreased $11.5 million, or 12.4%, in the first quarter of 2019 compared to the first quarter of 2018. The decrease was due primarily to lower turnaround activities and, to a lesser extent, lower construction activity compared to the record revenues achieved in the prior year quarter. These decreases were partially offset by a higher volume of maintenance services activity as we continue to expand our presence with existing customers.

35

Gross Profit and Gross Profit Margin

Gross profit decreased $2.4 million, or 21.2%, in the first quarter of 2019 compared to the first quarter of 2018 and gross profit margin declined 130 basis points in the first quarter of 2019 compared to the first quarter of 2018. The decreases in gross profit and gross profit margin were primarily due to a lower mix of higher-margin turnaround projects. Gross profit margin associated with maintenance activities also decreased slightly due to a greater mix of lower margin services.

Operating Expenses

Operating expenses decreased $0.4 million, or 5.0%, in the first quarter of 2019 compared to the first quarter of 2018. The decrease was primarily due to lower variable costs associated with decreased turnaround and construction activity as well as higher prior year costs to support the labor transitions at refineries to comply with labor laws in California. Operating expenses as a percentage of revenues were 9.5% in the first quarter of 2019 compared to 8.8% in the first quarter of 2018.

Operating Income and Operating Margin

Operating income decreased $2.0 million, or 64.3%, to $1.1 million in the first quarter of 2019 compared to $3.1 million in the first quarter of 2018, primarily due to the decreased turnaround and construction activities discussed above. Operating margin declined to 1.4% in the first quarter of 2019 compared to 3.4% in the first quarter of 2018.

Operating Expenses

Operating expenses decreased $1.8 million, or 23.4%, in the first quarter of 2019 compared to the first quarter of 2018. As part of our restructuring efforts, we recognized charges of $0.2 million in each of the first quarters of 2019 and 2018. The decrease in operating expenses was primarily due to: (i) decreased spending and other cost reduction initiatives as a result of the 2017 Restructuring; (ii) lower medical and prescription drug expenses as a result of improved claims history and changes to the structure of our medical plan to reduce costs; and (iii) lower incentive compensation expense. Corporate operating expenses as a percentage of consolidated revenues were 2.1% in the first quarter of 2019 compared to 2.3% in the first quarter of 2018.

Other Income (Expense)

Interest Income and Expense

Interest income increased $0.2 million in the first quarter of 2019 compared to the prior year quarter primarily due to interest received on the $8.0 million note receivable acquired in the Bayou sale during the third quarter of 2018. Interest expense decreased $1.9 million in the first quarter of 2019 compared to the prior year quarter primarily due to expenses of $1.7 million recorded in the first quarter of 2018 for certain arrangement and other fees associated with amending our credit facility as well as the write-off of previously unamortized deferred financing costs. Additionally, interest expense decreased due to reduced loan principal balances during the first quarter of 2019 compared to the first quarter of 2018, partially offset by higher LIBOR-based borrowing costs under our Credit Facility.

36

Other Expense

Other expense was $0.7 million and $0.3 million in the quarters ended March 31, 2019 and 2018. The balances primarily consisted of foreign currency transaction losses.

Tax Benefit on Loss

The tax benefit on the pre-tax loss was $0.8 million and $1.0 million in the first quarters of 2019 and 2018, respectively. Our effective tax rate was a benefit of 16.0% on a pre-tax loss in the quarter ended March 31, 2019 compared to a benefit of 40.4% on a pre-tax loss in the quarter ended March 31, 2018. During both periods, the effective rates were negatively impacted by valuation allowances recorded on certain net operating losses in foreign jurisdictions for which no income tax benefits are expected to be recognized. The effective tax rate for the quarter ended March 31, 2018, however, was positively impacted by a $1.5 million net tax benefit, or 60.0% benefit to the effective tax rate, related to employee share-based payments that vested during the first quarter of 2018.

Non-controlling Interests

Income attributable to non-controlling interests was less than $0.1 million in the quarter ended March 31, 2019 compared to income of $0.6 million in the quarter ended March 31, 2018. In the first quarter of 2019, income was primarily driven from our Corrosion Protection joint venture in Saudi Arabia and our Infrastructure Solutions joint ventures in Asia, partially offset by our Corrosion Protection joint ventures in Oman and South Africa. In the first quarter of 2018, income was primarily driven from our Corrosion Protection joint ventures in Louisiana, Saudi Arabia and Oman.

Liquidity and Capital Resources

Cash and Cash Equivalents

(in thousands)	March 31,   2019		December 31,   2018
Cash and cash equivalents	$	62,482	$	83,527
Restricted cash	1,235		1,359

Restricted cash held in escrow primarily relates to funds reserved for legal requirements, deposits made in lieu of retention on specific projects performed for municipalities and state agencies, or advance customer payments and compensating balances for bank undertakings in Europe.

Sources and Uses of Cash

We expect the principal operational use of funds for the foreseeable future will be for capital expenditures, working capital, debt service and share repurchases.

During the first quarter of 2019, capital expenditures were primarily used to: (i) support our Infrastructure Solutions North American CIPP business and expand our Corrosion Protection businesses in the Middle East; and (ii) boost our information systems platform with upgrades to our enterprise resource planning system. For 2019, we anticipate that we will spend approximately $25.0 to $30.0 million for capital expenditures, which is slightly below that in 2018.

In December 2018, our board of directors authorized the open market repurchase of up to two million shares of our common stock. The program did not establish a time period in which the repurchases had to be made. That authorization is now limited to $32.0 million in 2019 due to the December 2018 amendment to our Credit Facility. The shares are repurchased from time to time in the open market, subject to cash availability, market conditions and other factors, and in accordance with applicable regulatory requirements. We are not obligated to acquire any particular amount of common stock and, subject to applicable regulatory requirements, may commence, suspend or discontinue purchases at any time without notice or authorization. During the quarter ended March 31, 2019, we acquired 622,043 shares of our common stock for $11.1 million ($17.82 average price per share) through the open market repurchase program discussed above. In addition, we repurchased 152,946 shares of our common stock for $3.1 million ($20.48 average price per share) in connection with the satisfaction of tax obligations in connection with the vesting of restricted stock units and performance units. Any shares repurchased during 2019 are expected to be funded primarily through available cash. Once repurchased, we promptly retire such shares.

As part of our 2017 Restructuring, we utilized cash of $3.3 million during the first quarter of 2019 and $26.5 million in cumulative cash payments since 2017 related to employee severance, extension of benefits, employment assistance programs, early lease and contract termination and other restructuring related costs as we exit our non-pipe related contract applications

37

for the Tyfo^® system in North America, right-size our cathodic protection services operations in Canada, right-size our Infrastructure Solutions businesses in Australia and Denmark, and reduce corporate and other operating costs. Cumulatively, we have incurred both cash and non-cash charges of $142.5 million, of which $86.4 million relates to goodwill and long-lived asset impairment charges recorded in 2017 as part of exiting the non-pipe FRP contracting market in North America. We expect to incur additional cash and non-cash charges of $12 million to $16 million during 2019.

At March 31, 2019, our cash balances were located worldwide for working capital and support needs. Approximately $43.6 million, or 69.7%, of our cash was denominated in currencies other than the United States dollar as of March 31, 2019. We manage our worldwide cash requirements by reviewing available funds among the many subsidiaries through which we conduct business and the cost effectiveness with which those funds can be accessed. The repatriation of cash balances from certain of our subsidiaries could have adverse tax consequences or be subject to regulatory capital requirements; however, those balances are generally available without legal restrictions to fund ordinary business operations. At this time, we do not intend to distribute earnings in a taxable manner, and therefore, intend to limit distributions to: (i) earnings previously taxed in the U.S.; (ii) earnings that would qualify for the 100 percent dividends received deduction provided in the Tax Cuts and Jobs Act; or (iii) earnings that would not result in significant foreign taxes. As a result, we did not recognize a deferred tax liability on any remaining undistributed foreign earnings at March 31, 2019.

Our primary source of cash is operating activities. We occasionally borrow under our line of credit’s available capacity to fund operating activities, including working capital investments. Our operating activities include the collection of accounts receivable as well as the ultimate billing and collection of contract assets. At March 31, 2019, we believed our net accounts receivable and our contract assets, as reported on our Consolidated Balance Sheet, were fully collectible and a significant portion of the receivables will be collected within the next twelve months. From time to time, we have net receivables recorded that we believe will be collected but are being disputed by the customer in some manner. Disputes of this nature could meaningfully impact the timing of receivable collection or require us to invoke our contractual or legal rights in a lawsuit or alternative dispute resolution proceeding. If in a future period we believe any of these receivables are no longer collectible, we would increase our allowance for bad debts through a charge to earnings.

Cash Flows from Operations

Cash flows from operating activities used $6.6 million in the first quarter of 2019 compared to $1.3 million provided in the first quarter of 2018. The decrease in operating cash flow from the prior year period was primarily due to lower operating income during the first quarter of 2019 as compared to the first quarter of 2018, exclusive of non-cash charges in both periods. Additionally, cash flows during the quarters ended March 31, 2019 and 2018 were negatively impacted by $3.3 million and $4.4 million, respectively, in cash payments related to our restructuring activities. Working capital used $12.8 million of cash during the first quarter of 2019 compared to $12.6 million used in the first quarter of 2018.

Cash Flows from Investing Activities

Cash flows from investing activities used $7.8 million during the first quarter of 2019 compared to $5.0 million used during the first quarter of 2018. We used $8.1 million in cash for capital expenditures in the first quarter of 2019 compared to $5.2 million in the prior year period. In the first quarter of 2019 and 2018, $1.0 million of non-cash capital expenditures were included in accounts payable and accrued expenses in both periods. Capital expenditures in the first quarter of 2019 and 2018 were partially offset by $0.3 million and $0.3 million, respectively, in proceeds received from asset disposals.

Cash Flows from Financing Activities

Cash flows from financing activities used $7.1 million during the first quarter of 2019 compared to $16.9 million used in the first quarter of 2018. During the first quarter of 2019 and 2018, we used net cash of $13.3 million and $13.7 million, respectively, to repurchase 774,989 and 571,580 shares, respectively, of our common stock through open market purchases and in connection with our equity compensation programs as discussed in Note 9 to the consolidated financial statements contained in this report. During the first quarter of 2019, we had net borrowings of $13.0 million on our line of credit to fund domestic working capital needs. Additionally, during the first quarter of 2019, we used cash of $6.6 million to pay down the principal balance of our term loans. During the first quarter of 2018, we had net borrowings of $5.0 million from our line of credit primarily to fund domestic working capital needs, and we used cash of $6.6 million to pay down the principal balance of our term loan and used cash of $1.7 million to amend our original credit facility, as discussed in Note 8 to the consolidated financial statements contained in this report.

Long-Term Debt

In October 2015, the Company entered into an amended and restated $650.0 million senior secured credit facility with a syndicate of banks. In February 2018 and December 2018, the Company amended this facility (the “amended Credit Facility”).

38

Following the sale of Bayou, the amended Credit Facility consists of a $275.0 million five-year revolving line of credit and a $308.4 million five-year term loan facility, each with a maturity date in February 2023.

Our indebtedness at March 31, 2019 consisted of $275.6 million outstanding from the term loan under the amended Credit Facility and $44.0 million on the line of credit under the amended Credit Facility. Additionally, the Company had $0.9 million of debt held by its joint ventures (representing funds loaned by its joint venture partners) listed as held for sale at March 31, 2019 related to the planned sales of Corrpower and Aegion South Africa.

As of March 31, 2019, we had $22.6 million in letters of credit issued and outstanding under the amended Credit Facility. Of such amount, $12.3 million was collateral for the benefit of certain of our insurance carriers and $10.3 million was for letters of credit or bank guarantees of performance or payment obligations of foreign subsidiaries.

In October 2015, we entered into an interest rate swap agreement for a notional amount of $262.5 million, which is set to expire in October 2020. The notional amount of this swap mirrors the amortization of a $262.5 million portion of our $350.0 million term loan drawn from the Credit Facility. The swap requires us to make a monthly fixed rate payment of 1.46% calculated on the amortizing $262.5 million notional amount, and provides for us to receive a payment based upon a variable monthly LIBOR interest rate calculated on the same amortizing $262.5 million notional amount. The receipt of the monthly LIBOR-based payment offsets a variable monthly LIBOR-based interest cost on a corresponding $262.5 million portion of our term loan from the Credit Facility. This interest rate swap is used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and is accounted for as a cash flow hedge.

On March 12, 2018, we entered into an interest rate swap forward agreement that begins in October 2020 and expires in February 2023 to coincide with the amortization period of the amended Credit Facility. The swap will require us to make a monthly fixed rate payment of 2.937% calculated on the then amortizing $170.6 million notional amount, and provides for us to receive a payment based upon a variable monthly LIBOR interest rate calculated on the same amortizing $170.6 million notional amount. The receipt of the monthly LIBOR-based payment will offset the variable monthly LIBOR-based interest cost on a corresponding $170.6 million portion of our term loan from the amended Credit Facility. This interest rate swap will be used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and accounted for as a cash flow hedge.

The amended Credit Facility is subject to certain financial covenants including a consolidated financial leverage ratio and consolidated fixed charge coverage ratio. We were in compliance with all covenants at March 31, 2019 and expect continued compliance for the foreseeable future.

We believe that we have adequate resources and liquidity to fund future cash requirements and debt repayments with cash generated from operations, existing cash balances and additional short- and long-term borrowing capacity for the next 12 months.

See Note 8 to the consolidated financial statements contained in this report for additional information and disclosures regarding our long-term debt.

Disclosure of Contractual Obligations and Commercial Commitments

There were no material changes in contractual obligations and commercial commitments from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2018. See Note 11 to the consolidated financial statements contained in this report for further discussion regarding our commitments and contingencies.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market Risk

We are exposed to the effect of interest rate changes and of foreign currency and commodity price fluctuations. We currently do not use derivative contracts to manage commodity risks. From time to time, we may enter into foreign currency forward contracts to fix exchange rates for net investments in foreign operations to hedge our foreign exchange risk.

Interest Rate Risk

The fair value of our cash and short-term investment portfolio at March 31, 2019 approximated carrying value. Given the short-term nature of these instruments, market risk, as measured by the change in fair value resulting from a hypothetical 100 basis point change in interest rates, would not be material.

Our objectives in managing exposure to interest rate changes are to limit the impact of interest rate changes on earnings and cash flows and to lower overall borrowing costs. To achieve these objectives, we maintain fixed rate debt whenever favorable; however, the majority of our debt at March 31, 2019 was variable rate debt. We substantially mitigate our interest

39

rate risk through interest rate swap agreements, which are used to hedge the volatility of monthly LIBOR rate movement of our debt. We currently utilize interest rate swap agreements with a notional amount that mirrors approximately 75% of our outstanding borrowings from the term loan under our amended Credit Facility.

At March 31, 2019, the estimated fair value of our long-term debt was approximately $323.8 million. Fair value was estimated using market rates for debt of similar risk and maturity and a discounted cash flow model. Market risk related to the potential increase in fair value resulting from a hypothetical 100 basis point increase in our debt specific borrowing rates at March 31, 2019 would result in a $0.8 million increase in interest expense.

Foreign Exchange Risk

We operate subsidiaries and are associated with licensees and affiliated companies operating solely outside of the United States and in foreign currencies. Consequently, we are inherently exposed to risks associated with the fluctuation in the value of the local currencies compared to the U.S. dollar. At March 31, 2019, a substantial portion of our cash and cash equivalents was denominated in foreign currencies, and a hypothetical 10% change in currency exchange rates could result in an approximate $5.0 million impact to our equity through accumulated other comprehensive income (loss).

In order to help mitigate this risk, we may enter into foreign exchange forward contracts to minimize the short-term impact of foreign currency fluctuations. We do not engage in hedging transactions for speculative investment reasons. There can be no assurance that our hedging operations will eliminate or substantially reduce risks associated with fluctuating currencies. At March 31, 2019, there were no material foreign currency hedge instruments outstanding. See Note 13 to the consolidated financial statements contained in this report for additional information and disclosures regarding our derivative financial instruments.

Commodity Risk

We have exposure to the effect of limitations on supply and changes in commodity pricing relative to a variety of raw materials that we purchase and use in our operating activities, most notably resin, chemicals, staple fiber, fuel, metals and pipe. We manage this risk by entering into agreements with certain suppliers utilizing a request for proposal, or RFP, format and purchasing in bulk, and advantageous buying on the spot market for certain metals, when possible. We also manage this risk by continuously updating our estimation systems for bidding contracts so that we are able to price our products and services appropriately to our customers. However, we face exposure on contracts in process that have already been priced and are not subject to any cost adjustments in the contract. This exposure is potentially more significant on our longer-term projects.

We obtain a majority of our global resin requirements, one of our primary raw materials, from multiple suppliers in order to diversify our supplier base and thus reduce the risks inherent in concentrated supply streams. We have qualified a number of vendors in North America, Europe and Asia that can deliver, and are currently delivering, proprietary resins that meet our specifications.

The primary products and raw materials used by our infrastructure rehabilitation operations in the manufacture of fiber reinforced polymer composite systems are carbon, glass, resins, fabric and epoxy raw materials. Fabric and epoxies are the largest materials purchased, which are currently purchased through a select group of suppliers, although we believe these and the other materials are available from a number of vendors. The price of epoxy historically is affected by the price of oil. In addition, a number of factors such as worldwide demand, labor costs, energy costs, import duties and other trade restrictions may influence the price of these raw materials.

We rely on a select group of third-party extruders to manufacture our Fusible PVC^® pipe products.

Item 4. Controls and Procedures

Our management, under the supervision and with the participation of our Chief Executive Officer (our principal executive officer) and Chief Financial Officer (our principal financial officer), has conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of March 31, 2019. Based upon and as of the date of this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act (a) is recorded, processed, summarized and reported within the time period specified in the Securities and Exchange Commission’s rules and forms and (b) is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

During the quarter ended March 31, 2019, we implemented new controls as part of our efforts to adopt FASB ASC 842. These new controls relate to: (i) gathering, monitoring and assessing the necessary lease data; and (ii) a new third-party

40

software as a system to capture, calculate and properly account for leases under FASB ASC 842. There were no other changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2019 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

41

PART II—OTHER INFORMATION

Item 1. Legal Proceedings

We are involved in certain actions incidental to the conduct of our business and affairs. Management, after consultation with legal counsel, does not believe that the outcome of any such actions, individually and in the aggregate, will have a material adverse effect on our consolidated financial condition, results of operations or cash flows.

Item 1A. Risk Factors

There have been no material changes to the risk factors described in Items 1A in our Annual Report on Form 10-K for the year ended December 31, 2018.

_________________________________

⁽¹⁾  In December 2018, our board of directors authorized the open market repurchase of up to two million shares of our common stock beginning January 1, 2019. Any shares repurchased are pursuant to one or more 10b5-1 plans. The program expires on the earlier of the repurchase by the Company of two million shares of common stock pursuant to the program or the board of directors' termination of the program. In December 2018, we amended our senior secured credit facility, which limits the open market repurchase of our common stock to be made during 2019 to $32.0 million. We began repurchasing shares under this program in January 2019. Once repurchased, we promptly retired the shares.

⁽²⁾  In connection with approval of our credit facility, our board of directors approved the purchase of up to $10.0 million of our common stock in each calendar year in connection with our equity compensation programs for employees and directors. The number of shares purchased includes shares surrendered to us to pay the exercise price and/or to satisfy tax withholding obligations in connection with “net, net” exercises of employee stock options and/or the vesting of restricted stock, restricted stock units or performance units issued to employees. During the quarter ended March 31, 2019, 48,409 shares were surrendered in connection with stock swap transactions and 104,537 shares were surrendered in connection with restricted stock unit and performance unit transactions. The deemed price paid was the closing price of our common stock on the Nasdaq Global Select Market on the date that the restricted stock units or performance units vested. Once repurchased, we promptly retired the shares.

Exhibit 10.1

AEGION CORPORATION

MANAGEMENT ANNUAL INCENTIVE PLAN

CORPORATE EMPLOYEES

This Management Annual Incentive Plan (the “Plan”) of Aegion Corporation (the “Company”) is effective as of the 1^st day of January 2019.

A. Plan Purpose

The purpose of this Plan is to enhance business performance by motivating and rewarding executive and management employees for the achievement of incentive goals structured to achieve desired corporate results.

B. Eligible Employees

A committee comprised of the Company’s Chief Executive Officer, General Counsel, Chief Financial Officer and Senior Vice President - Human Resources (together, the “Plan Committee”), shall designate the employees of the Company and its subsidiaries who are to be participants (the “Participants”) in the Plan for the applicable fiscal year, which, in this case, is January 1, 2019 through December 31, 2019 (the “Plan Year”).

Except where prohibited by law, as a condition to participation in the Plan and the receipt of any payment hereunder, Participants shall be required to sign any (i) confidentiality, non-solicitation and/or non-competition agreement, (ii) acknowledgement of the Company’s right to recoup any incentive compensation and/or (iii) acknowledgment of and agreement to comply with the Company’s Code of Conduct, each as may be required by the Company. Certain Participants who are employees of a business unit may participate in both this Plan and the plan for business unit employees, with a total award based in part on performance in this Plan and in part on performance under the plan for business unit employees.

To be eligible for payment under the Plan, an employee must be a current employee in good standing at the time of payout, which includes, but is not limited to, completing the Company’s annual compliance training requirements within the time period provided for completion. In addition, to be eligible for payment under the Plan, a Participant must have up to date performance reviews completed by June 30, 2019 and individual personal objectives in place by March 31, 2019 for each of the Participant’s direct reports. The Company has the right, in its sole discretion, to determine whether an employee is in good standing and/or otherwise eligible for a Plan award.

C. Participant Incentive Award Goals

The Plan Committee shall establish an incentive award goal (a “Goal”) for each Participant that shall be expressed as a percentage of such Participant’s annual base salary. Participant Goals shall be reviewed and approved by the Plan Committee on an annual basis. The Compensation Committee of the Board of Directors of the Company (the “Compensation Committee”) shall approve Goals and Bookings Targets (as defined below), if applicable, of all executive officers of the Company.

D. Funding and Award Summary

Each Participant’s Goal shall be measured and achieved through two separately weighted elements: (a) a Financial Goal weighted at 75% of the overall Goal; and (b) a Non-Financial Goal weighted at 25% of the overall Goal.

Financial Goal: 75% of each Goal under the Plan (the “Financial Goal”) shall be based upon total Company performance for the Plan Year or portion of Plan Year, as applicable for the biannual awards described in Section H of this Plan (the “Biannual Awards”),¹ subject to the discretion of the Compensation Committee based upon other subjective performance factors. Total Company performance shall be measured based on the actual consolidated Company EBT (as defined below) achieved (“Actual EBT”) as compared against the targeted consolidated Company EBT (“EBT Target”) for the Plan Year, or portion of Plan Year, as applicable for the Biannual Awards (“Biannual EBT Targets”), each as approved by the Compensation Committee; provided, however, with respect to only Participants who have, as a primary job function, the oversight of sales (“Chief Sales Officer”), 50% of the Financial Goal shall be measured based on the actual consolidated Company Bookings (as defined below) achieved for the Plan Year (“Actual Bookings”) as compared against the target Bookings (“Bookings Target”) for the Plan Year, or portion of Plan Year, as applicable for the Biannual Awards (“Biannual Bookings Targets”), as approved by the Company’s Chief Executive Officer, and the remaining 50% of the Financial Goal shall be based on Actual EBT.

Non-Financial Goal: 25% of each Goal under the Plan shall be based upon the achievement of at least three of four individual personal objectives for the Plan Year (the “Non-Financial Goal”). A Participant’s individual personal objectives for the Plan Year shall be approved by the Participant’s direct supervisor no later than March 31, 2019; however, a Participant and his/her direct supervisor may jointly modify a Participant’s objectives during the Plan Year if circumstances warrant. A Participant’s achievement of such objectives shall be determined by the Participant’s direct supervisor. A Participant’s achievement of at least three of their personal objectives shall entitle them to a 25% payout of his/her Goal. Failure to achieve at least three personal objectives will result in zero payout of the Non-Financial Goal. The Non-Financial Goal is an “all or nothing” pay-out goal. A Participant will be eligible for full payment of the Non-Financial Goal regardless of whether the Annual EBT Target is achieved. In the event a Participant achieves his/her Non-Financial Goal, and if the Company exceeds the Annual EBT Target, the Participant shall be eligible to receive greater than the 25% payout amount in accordance with the payout schedule set forth in Exhibit A. The Company’s failure to achieve at least 100% of the Annual EBT Target shall not impact the funding or payment of the Non-Financial Goal.

E. EBT and Bookings

For purposes of this plan, “EBT” shall be defined as “income before taxes on income and before extraordinary items less income/(loss) before taxes of non-controlling interests” of the Company for the Plan Year, which shall mean the consolidated income before taxes on income and less income/(loss) before taxes of non-controlling interests of the Company during the fiscal year, as determined by the Plan Committee in conformity with accounting principles generally accepted in the United States of American and contained in financial statements that are subject to an audit report of the Company’s independent public accounting firm, but excluding:

(i) operating results and/or losses associated with the write-down of assets of a subsidiary, business unit or division that has been designated by the Board of Directors as a discontinued business operation or to be liquidated;

(ii) gains or losses on the sale of any subsidiary, business unit or division, or the assets or business thereof;

(iii) gains or losses from the disposition of material capital assets (other than in a transaction described in subsection (ii)) or the refinancing of indebtedness, including, among other things, any make-whole payments and prepayment fees;

1 All references to the Plan Year include applicable portions of the Plan Year, as they apply to the Biannual Awards described in Section H of this Plan.

(iv) losses associated with the write-down of goodwill or other intangible assets of the Company due to the determination under applicable accounting standards that the assets have been impaired;

(v) gains or losses from material property casualty occurrences or condemnation awards, taking into account the proceeds paid by insurance companies and other third parties in connection with the casualty or condemnation;

(vi) any income statement effect resulting from a change in tax laws, accounting principles (including, without limitation, generally accepted accounting principles), regulations, or other laws regulations affecting reported results, except, in each case, to the extent the effect of such a change is already reflected in the target EBT amount;

(vii) reorganization or restructuring charges and acquisition- or divestiture-related transaction expenses and costs;

(viii) any gains or losses from unusual nonrecurring or extraordinary items;

(ix) operating results of any entity or business acquired or disposed of during the Plan Year, except, in the case of an acquisition, to the extent such entity or business was included in the Company’s operating business plan for the Plan Year or, in the case of a disposition, to the extent such entity or business was not included in the Company’s operating business plan for the Plan Year;

(x) any gain or loss resulting from currency fluctuations or translations as set forth in the Aegion Corporation Foreign Exchange Rate Policy for Annual Incentive Plan and Long- Term Incentive Plan;

(xi) any material income or loss item the realization of which is not directly attributable to the actions of current senior management of the Company; and

(xii) the income taxes (benefits of any of the above-designated gains or losses.

For purposes of this Plan, “Bookings” shall be defined as either (i) actual consolidated orders booked by the Company for the Plan Year (reduced by any previously recorded orders that were cancelled during the Plan Year), or (ii) actual consolidated gross profit for actual consolidated orders booked by the Company for the Plan Year (reduced by the actual gross profit associated with any previously recorded orders that were canceled during the Plan Year), each of which shall be calculated and determined by the Company’s Chief Financial Officer in a manner consistent with how the Company records and reports hard backlog.

The Compensation Committee shall have final authority with respect to any determination by the Plan Committee regarding the definition of “EBT” and “Bookings” and, in exercising such authority, may consult with the Company’s independent auditor and/or Audit Committee as it deems necessary and advisable.

F. Consolidated Company Financial Performance Pool Funding

The Financial Goal portion of the Plan, as well as any payout amount exceeding the Non- Financial Goal portion of the Plan (i.e. amounts exceeding 25% of the overall Goal), shall be funded based on the EBT performance and Bookings performance of the Company as a whole (such funding pool shall be referred to as the “Consolidated Company Financial Performance Pool”). At the outset of each Plan Year, the Compensation Committee shall determine (i) the EBT Target for the Plan Year; (ii) with respect to Sales Participants who are executive officers, if applicable, the Bookings Target for the Plan Year; and

(iii) the target funding amount (the “Company Target Funding Amount”) based on both the EBT Target and the Bookings Target for the Consolidated Company Financial Performance Pool. The actual amount funded to the Consolidated Company Financial Performance Pool shall be determined upon calculation of Actual EBT and Actual Bookings after the end of the Plan Year, subject to any adjustments required pursuant to Section E hereof.

1. If Actual EBT equals the EBT Target, the portion of the Consolidated Company Financial Performance Pool related to EBT shall be equal to the portion Company Target Funding Amount related to EBT, subject to the additional terms specified in Exhibit A.

2. If Actual EBT exceeds or falls below the EBT Target, the portion of Consolidated Company Financial Performance Pool related to EBT shall be determined in accordance with the chart in Exhibit A (using interpolation for Actual EBT levels as specified therein), and subject to the additional terms specified therein.

3. If Actual EBT is less than the threshold percentage of the EBT Target specified in the chart in Exhibit A, the maximum amount funded to the Consolidated Company Financial Performance Pool shall be equal to $500,000; provided, however, that (i) such amount shall only be awarded to individual Participants for extraordinary performance, as determined by the Company’s Chief Executive Officer in his sole discretion (subject to the review and approval by the Compensation Committee of any awards to executive officers of the Company); (ii) such amount shall be reduced such that any funding under this paragraph and the similar mechanism in Section F(13) of the Management Annual Incentive Plan for Business Unit Employees shall together not exceed $500,000.

4. If Actual Bookings equals the Bookings Target, the portion of the Consolidated Company Financial Performance Pool related to Bookings shall be equal to the portion of Company Target Funding Amount related to Bookings, subject to the additional terms specified in Exhibit B.

5. If Actual Bookings exceed or falls below the Bookings Target, the portion of the Consolidated Company Financial Performance Pool related to Bookings shall be determined in accordance with the chart in Exhibit B (using interpolation for Actual Bookings levels as specified therein), and subject to the additional terms specified therein.

6. If Actual Bookings are less than the threshold percentage of the Bookings Target (after the threshold percentage has been determined by the Chief Executive Officer in his sole discretion, per Exhibit B), the amount funded to the Consolidated Company Financial Performance Pool shall be equal to $0.

The maximum funding amount for the Consolidated Company Financial Performance Pool shall be 200% of the Company Target Funding Amount. In all events, the Compensation Committee, subject to any required approval of the Board of Directors, shall have the ability and authority to increase or decrease the amount of the Consolidated Company Financial Performance Pool calculated in accordance with the provisions of this Plan to reflect any extraordinary or unforeseen events or occurrences during the Plan Year.

G. Consolidated Company Financial Performance Bonus Pool Awards

The Consolidated Company Financial Performance Pool Shall be awarded to Participants subject to available pool funding. Except as otherwise provided in Section L below, a Participant must be an employee in good standing at the time the award is paid. The Company has the right, in its sole discretion, to determine whether an employee is in good standing and/or otherwise eligible for a Plan award.

H. Award Opportunities for Non-Sales Participants

Each non-sales Participant has the following opportunities to be paid an Award:

1. 1H2019 Award

• Participants who are Section 16 Officers of the Company on June 30, 2019

2. 2H2019 Award

However, if the Annual EBT Target exceeds 100% of EBT Target, the Personal Objective Award may be increased according to the payout schedule in the Annual EBT Chart in Exhibit A.

If the Company achieves its EBT threshold for the Plan Year, each non-Sales Participant shall be eligible to receive an Annual Award of up to 200% of his/her Financial Goal (“Annual Award”), less the amount of any 1H2019 Award and/or 2H2019 Award paid to the Participant and subject to the payout offsets described in Section J. The payout scale shall be as follows:

• If actual EBT is less than 75% of the EBT Target, the Consolidated Company Financial Performance Pool shall not be funded (subject to Section F(3)).

• If actual EBT is at least 100% of the EBT Target but less than 110% of EBT Target, each Participant shall be eligible to receive a minimum of 100% of his/her Financial Goal.

• If actual EBT is at least 110% of the EBT Target but less than 120% of EBT Target, each Participant shall be eligible to receive a minimum of 150% of his/her Financial Goal.

• To the extent the Company’s actual EBT is greater than 75% of Target EBT but less than 100% of Target EBT, or greater than 100% of Target EBT but less than 120% of Target EBT, the payout level shall be calculated based on a straight-line, sliding scale using the performance levels (75% and 100%, on the one hand, and 100% and 120%, onthe other hand) between which the Company’s actual performance falls as the end points for this calculation.

I. Award Opportunities for Chief Sales Officer

If specifically and separately designated in writing by the Chief Executive Officer as eligible for an AIP award in 2019, the Chief Sales Officer has the opportunity to be paid an Annual Award, as follows:

• 25% of the target payout is tied to a Non-Financial Goal, as set forth herein.

• 75% of the target payout is tied to a Financial Sales Goal, defined as follows:

◦ 50% of the target payout for each Sales Participant tied to a Financial Sales Goal shall be based on EBT, as described in Section H, and as set forth in the payout scale in Exhibit A (the “EBT Sales Goal”).

◦ 50% of the target payout tied to a Financial Sales Goal shall be based on Bookings, as set forth in the payout scale in Exhibit B, and in accordance with the following parameters (the “Bookings Sales Goal”):

• If Actual Bookings are less than 95% of the Bookings Target (at 100%), the Bookings Sales Goal shall not be funded with respect to Bookings.

• The Target Payout percentage for the threshold Bookings Target for the Chief Sales Officer with Bookings Goals also shall be equal to the average of the percentage of Target Payout for each of the three Senior Vice Presidents of Sales, or as otherwise designated, for the Company’s three platforms.

• To the extent the Company’s Actual Bookings are greater than the threshold Bookings Target but less than 100% of Bookings Target, or greater than 100% of the Bookings Target but less than the maximum Bookings Target, the payout level of the Bookings Sales Goal shall be calculated based on a straight-line, sliding scale using the performance levels (threshold and target, on the one hand, and target and maximum, on the other hand) between which the Company’s Actual Bookings performance falls as the end points for this calculation.

J. Payout Offsets for 2H2019 and Annual Awards

For 2H2019 and Annual Awards, once performance criteria have been met and a Target Payout has been calculated per the tables above, Financial Goal payouts may be reduced subject to one or more of the following offsets:

• Payouts shall be reduced by 17% if the Company fails to achieve its Company consolidated DSO target for 2019.

• Payout shall be reduced by 17% if the Company fails to achieve its Company consolidated Total Recordable Incident Rate (“TRIR”) goal for 2019.

• Annual Awards shall be offset by amounts paid for 1H2019 and H2019 Awards. In the event that a Participant receives a 1H2019 and/or 2H2019 Award, but is not eligible for an Annual Award due to failure to meet the Annual EBT threshold, the Participant will not be required to pay back the 1H2019 and/or 2H2019 Award or any portion thereof.

Payment shall be made within 30 days of the date of death. For these purposes, “Beneficiary” means the Participant’s surviving spouse and, if the Participant leaves no surviving spouse, the Participant’s estate.

The amount of such award shall be based on the Participant’s annualized base salary and the target award level (i.e., without regard to actual performance). Payment shall be made within 30 days of the date of the Disability. For these purposes, “Disability” means that the Participant is, by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months, receiving income replacement benefits for a period of not less than three months under an accident and health plan covering employees of the Company. A Participant who incurs a Disability between January 1, 2019 and the 1H2019 Award payout date (as set forth in Section K) will not be eligible to receive a 1H2019 Award or 2H2019 Award. A Participant who incurs a Disability between July 1, 2019 and the 2H2019 payout date (as set forth in Section K) will not be eligible to receive a 2H2019 Award.

In the event of a Change in Control (as defined below), outstanding awards shall become payable, based on the annualized base salary of each Participant, prorated based on the days in the Plan Year prior to the Change in Control, using the greater of the actual performance at the date of the Change in Control or the target award level. Payment shall be made within 30 days of the date of the Change in Control and will be offset by payments made for 1H2019 and/or 2H2019 Awards. For these purposes, a “Change in Control” shall mean (i) the acquisition by one person, or more than one person acting as a group, in a transaction or series of related transactions, of ownership of stock of the Company that, together with stock held by such person or group, constitutes more than 30% of the total fair market value or total voting power of the stock of the Company; and/or (ii) a majority of the members of the Company’s Board of Directors is replaced during any twelve-month period by directors whose appointment or election is not endorsed by a majority of the members of the Company’s Board of Directors before the date of the appointment or election; and/or (iii) the consummation of a merger or consolidation of the Company other than a merger or consolidation that would result in the voting securities of the Company outstanding immediately prior to the transaction continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or any parent thereof) at least 50% of the combined voting power of the securities of the Company or such surviving entity or any parent thereof outstanding immediately after such merger or consolidation; and/or (iv) the stockholders of the Company approve a plan of complete liquidation or dissolution of the Company or there is a consummated sale or disposition by the Company of all or substantially all of the Company’s assets, other than a sale or disposition by the Company of all or substantially all of the Company’s assets to an entity, at least 50% of the combined voting power of the voting securities of which are owned by stockholders of the Company in substantially the same proportions as their ownership of the Company immediately prior to such sale.

Deferred Stock Units that have not vested upon your termination of service from the Company’s Board of Directors will be automatically and immediately forfeited and you will have no right to receive the underlying related Common Stock. However, if your termination of service from the Company’s Board of Directors is due to your Retirement (as defined below), you will receive a cash payment upon Retirement equal to the closing price of the Company’s Common Stock on the date of your Retirement multiplied by the number of unvested Deferred Stock Units that were forfeited and by a fraction, the numerator of which is the number of days of service you completed during the vesting period, and the denominator of which is three hundred sixty-five (365). For these purposes, “Retirement” means your voluntary resignation from the Company's Board of Directors for reasons unrelated to death, disability or Change in Control.

Your Deferred Stock Units are not transferable by you. Except as may be required by federal income tax withholding provisions or by the tax laws of any state, your interests (and the interests of your beneficiaries, if any) under this Agreement are not subject to the claims of your creditors and may not be voluntarily or involuntarily sold, transferred, alienated, assigned, pledged, anticipated, or encumbered. Any attempt to sell, transfer, alienate, assign, pledge, anticipate, encumber, charge or otherwise dispose of any right to benefits payable hereunder shall be void.

3.Distribution of Shares of Common Stock.

Promptly after the date(s) you specified in a written distribution election filed with the Company on or before December 31, 2018, shares of Common Stock equal to the number of vested Deferred Stock Units reflected in your Deferred Stock Unit Account, shall be distributed to you in accordance with your election. If you did not file such an election, distribution with respect to vested Deferred Stock Units will be made promptly following your termination of service on the Company’s Board of Directors, or, if earlier, upon a Change in Control. Distributions shall be made in shares of Common Stock, with fractional shares rounded up to the nearest whole share.

4.     Death Beneficiary Designation. You may designate a beneficiary or beneficiaries (contingently, consecutively or successively) to receive shares of Common Stock, if you die while Deferred Stock Units are held in your Deferred Stock Unit Account, and, upon your death, the Company will transfer shares of Common Stock equal in number to the vested Deferred Stock Units, if any, reflected in your Deferred Stock Unit Account to your beneficiary(ies).

You may designate a beneficiary or beneficiaries from time to time, and you may change your designated beneficiary(ies). A beneficiary may be a trust. A beneficiary designation must be made in writing in a form prescribed by the Company and delivered to the Company while you are alive. If you do not have a designated beneficiary surviving at the time of your death, any transfer of shares of Common Stock will be made to your surviving spouse, if any, and if you do not have a surviving spouse, then to your estate.

5.Cash Dividend Equivalents; Adjustments. If the Company pays a cash dividend on its Common Stock, then, as soon as practical after such cash dividend is paid, the Company will pay you an amount in cash equal to the amount per share of such cash dividend multiplied by the number of Deferred Stock Units credited to your Deferred Stock Unit Account as of the record date of such cash dividend. Notwithstanding the foregoing, dividend equivalents payable with respect to unvested Deferred Stock Units will be payable on the one-year anniversary of grant.

If there is any change in the Common Stock by reason of stock dividends, split-ups, mergers, consolidations, reorganizations, combinations or exchanges of shares or the like, the number of Deferred Stock Units credited to your Deferred Stock Unit Account shall be adjusted appropriately so that the number of Deferred Stock Units reflected in your Deferred Stock Unit Account after such an event shall equal the number of shares of Common Stock a stockholder would own after such an event if the stockholder, at the time such an event occurred, had owned shares of Common Stock equal to the number of Deferred Stock Units reflected in your Deferred Stock Unit Account immediately before such an event.

6.No Stockholder Rights. You will not have any stockholder rights, such as rights to vote or to receive dividends or other distributions, with respect to any Deferred Stock Units reflected in your Deferred Stock Unit Account. You will have only the cash dividend equivalent and adjustment rights provided in this Agreement.

7.Securities Laws. Shares of Common Stock will not be transferred under this Agreement if such transfer would violate any federal or state securities law. The Company may take any appropriate action to achieve compliance with those laws in connection with any transfer of Common Stock to you.

8.No Right to Further Grants. Deferred Stock Unit grants are within the discretion of the Plan Administrator, and no such grant entitles you to any further grants.

9.Interpretations Binding. Plan Administrator interpretations and determinations are binding and conclusive.

10.Notices. Notices to the Company or the Plan Administrator shall be sent to the Company’s Corporate Headquarters, Attn: “General Counsel.”

Organization, Consolidation and Presentation of Financial Statements [Abstract]

General

GENERAL

The accompanying unaudited consolidated financial statements of Aegion Corporation and its subsidiaries (collectively, “Aegion” or the “Company”) reflect all adjustments (consisting only of normal recurring adjustments) that are, in the opinion of management, necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the dates and periods presented. Results for interim periods are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period. All significant intercompany related accounts and transactions have been eliminated in consolidation.

The Consolidated Balance Sheet as of December 31, 2018, which is derived from the audited consolidated financial statements, and the interim unaudited consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), the requirements of Form 10-Q and Article 10 of Regulation S-X and, consequently, do not include all information or footnotes required by GAAP for complete financial statements or all the disclosures normally made in an Annual Report on Form 10-K. Accordingly, the unaudited consolidated financial statements included herein should be read in conjunction with the audited consolidated financial statements and footnotes included in the Company’s 2018 Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 1, 2019.

Acquisitions/Strategic Initiatives/Divestitures

2017 Restructuring

On July 28, 2017, the Company’s board of directors approved a realignment and restructuring plan (the “2017 Restructuring”). As part of the 2017 Restructuring, the Company announced plans to: (i) divest the Company’s pipe coating and insulation businesses in Louisiana, The Bayou Companies, LLC and Bayou Wasco Insulation, LLC (collectively “Bayou”; (ii) exit all non-pipe related contract applications for the Tyfo^® system in North America; (iii) right-size the cathodic protection services operation in Canada and the CIPP businesses in Australia and Denmark; and (iv) reduce corporate and other operating costs.

During 2018, the Company’s board of directors approved additional actions with respect to the 2017 Restructuring, which included the decisions to: (i) divest the Australia and Denmark CIPP businesses; (ii) take actions to further optimize operations within North America, including measures to reduce consolidated operating costs; and (iii) divest or otherwise exit multiple additional international businesses. See Note 4.

Infrastructure Solutions Segment (“Infrastructure Solutions”)

On May 14, 2018, the Company’s board of directors approved a plan to divest the Company’s CIPP business in Australia (“Insituform Australia”). While restructuring actions in Insituform Australia led to improvements in operating results, an assessment of the long-term fit within the Company’s portfolio led to the decision to divest the business. Accordingly, the Company has classified Insituform Australia’s assets and liabilities as held for sale on the Consolidated Balance Sheet at March 31, 2019 and December 31, 2018. See Note 5.

Corrosion Protection Segment (“Corrosion Protection”)

During the first quarter of 2019, the Company initiated plans to sell its interest in its cathodic protection materials manufacturing and production joint venture in Saudi Arabia, Corrpower International Limited (“Corrpower”) and its interest in its Titeliner^® and CIPP joint venture in South Africa, Aegion South Africa Proprietary Limited (“Aegion South Africa”). Accordingly, the Company has classified the assets and liabilities of both businesses as held for sale on the Consolidated Balance Sheet at March 31, 2019. See Note 5.

Accounting Policies [Abstract]

Accounting Policies

ACCOUNTING POLICIES

On January 1, 2019, the Company adopted FASB ASC 842, Leases (“FASB ASC 842”). See Note 6 for further information. Other than the adoption of FASB ASC 842, there were no material changes in accounting policies from those disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Accumulated Other Comprehensive Income (Loss)

As set forth below, the Company’s accumulated other comprehensive loss is comprised of three main components: (i) currency translation; (ii) derivatives; and (iii) gains and losses associated with the Company’s defined benefit plan in the United Kingdom (in thousands):

	March 31,   2019			December 31, 2018
Currency translation adjustments	$	(39,158	)	$	(41,107	)
Derivative hedging activity	(431		)	1,715
Pension activity	(919		)	(898		)
Total accumulated other comprehensive loss	$	(40,508	)	$	(40,290	)

For the Company’s international subsidiaries, the local currency is generally the functional currency. Assets and liabilities of these subsidiaries are translated into U.S. dollars using rates in effect at the balance sheet date while revenues and expenses are translated into U.S. dollars using average exchange rates. The cumulative translation adjustment resulting from changes in exchange rates are included in the Consolidated Balance Sheets as a component of “Accumulated other comprehensive loss” in total stockholders’ equity. Net foreign exchange transaction losses of $0.8 million and $0.3 million in the first quarters of 2019 and 2018, respectively, are included in “Other expense” in the Consolidated Statements of Operations.

Taxation

The Company provides for estimated income taxes payable or refundable on current year income tax returns as well as the estimated future tax effects attributable to temporary differences and carryforwards, based upon enacted tax laws and tax rates, and in accordance with FASB ASC 740, Income Taxes (“FASB ASC 740”). FASB ASC 740 also requires that a valuation allowance be recorded against any deferred tax assets that are not likely to be realized in the future. The determination is based on the Company’s ability to generate future taxable income and, at times, is dependent on its ability to implement strategic tax initiatives to ensure full utilization of recorded deferred tax assets. Should the Company not be able to implement the necessary tax strategies, it may need to record valuation allowances for certain deferred tax assets, including those related to foreign income tax benefits. Significant management judgment is required in determining the provision for income taxes, deferred tax assets and liabilities and any valuation allowances recorded against net deferred tax assets.

Earnings per Share

Earnings per share have been calculated using the following share information:

	Quarters Ended   March 31,
	2019	2018
Weighted average number of common shares used for basic EPS	31,704,923	32,483,963
Effect of dilutive stock options and restricted and deferred stock unit awards	—	—
Weighted average number of common shares and dilutive potential common stock used for dilutive EPS	31,704,923	32,483,963

The Company excluded 549,679 restricted and deferred stock units for the quarter ended March 31, 2019, and 710,173 restricted and deferred stock units and stock options for the quarter ended March 31, 2018 from the diluted earnings per share calculation for the Company’s common stock because of the reported net loss for the periods.

Cash, Cash Equivalents and Restricted Cash

The Company classifies highly liquid investments with original maturities of 90 days or less as cash equivalents. Recorded book values are reasonable estimates of fair value for cash and cash equivalents.

Cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheets and Consolidated Statements of Cash Flows are as follows (in thousands):

Balance sheet data	March 31,   2019		December 31,   2018
Cash and cash equivalents	$	62,482	$	83,527
Restricted cash	1,235		1,359
Cash, cash equivalents and restricted cash	$	63,717	$	84,886

Restricted cash held in escrow primarily relates to funds reserved for legal requirements, deposits made in lieu of retention on specific projects performed for municipalities and state agencies, or advance customer payments and compensating balances for bank undertakings in Europe. Restricted cash related to operations is similar to retainage, and is, therefore, classified as a current asset, consistent with the Company’s policy on retainage.

Investments in Variable Interest Entities

The Company evaluates all transactions and relationships with variable interest entities (“VIE”) to determine whether the Company is the primary beneficiary of the entities in accordance with FASB ASC 810, Consolidation. There were no changes in the Company’s VIEs during the quarter ended March 31, 2019.

Financial data for consolidated variable interest entities are summarized in the following tables (in thousands):

Balance sheet data	March 31,   2019(1)		December 31,   2018

Newly Issued Accounting Pronouncements

In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement: Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for Level 1, Level 2 and Level 3 instruments in the fair value hierarchy. The guidance is effective for the Company’s fiscal year beginning January 1, 2020, including interim periods within that fiscal year. The adoption of this standard is not expected to have a material impact on its consolidated financial statements.

In February 2018, the FASB issued Accounting Standards Update No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits a company to reclassify the income tax effects of the Tax Cuts and Jobs Act on items within accumulated other comprehensive income to retained earnings. Companies may adopt the new guidance using one of two transition methods: (i) retrospective to each period (or periods) in which the income tax effects are recognized, or (ii) at the beginning of the period of adoption. The Company adopted this standard effective January 1, 2019 and elected not to reclassify the tax effects due to the immaterial impact on the Company’s consolidated financial statements.

In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Measurement of Credit Losses on Financial Instruments, which changes the way in which entities estimate and present credit losses for most financial assets, including accounts receivable. The guidance is effective for the Company’s fiscal year beginning January 1, 2020, including interim periods within that fiscal year. Early adoption is permitted, although the Company does not intend to do so. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842), which requires lessees to present right-of-use assets and lease liabilities on the balance sheet for all leases with lease terms longer than twelve months. The Company adopted this standard, effective January 1, 2019, using the adoption-date transition provision, which recognizes and measures leases existing at January 1, 2019 but without retrospective application. See Note 6.

Revenue from Contract with Customer [Abstract]

Revenues

REVENUES

On January 1, 2018, the Company adopted FASB ASC 606 for all contracts that were not completed using the modified retrospective transition method. The Company recognized the cumulative effect of initially applying FASB ASC 606 as a net reduction to opening retained earnings of $0.3 million as of January 1, 2018 due to the cumulative impact of adopting FASB ASC 606, with the impact primarily related to royalty license fee revenues.

Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in FASB ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. For contracts in which construction, engineering and installation services are provided, there is generally a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. The bundle of goods and services represents the combined output for which the customer has contracted. For product sales contracts with multiple performance obligations where each product is distinct, the Company allocates the contract’s transaction price to each performance obligation using its best estimate of the standalone selling price of each distinct good in the contract. For royalty license agreements whereby intellectual property is transferred to the customer, there is a single performance obligation as the license is not separately identifiable from the other goods and services in the contract.

The Company’s performance obligations are satisfied over time as work progresses or at a point in time. Revenues from products and services transferred to customers over time accounted for 92.9% and 95.0% of revenues for the quarters ended March 31, 2019 and 2018, respectively. Revenues from construction, engineering and installation services are recognized over time using an input measure (e.g., costs incurred to date relative to total estimated costs at completion) to measure progress toward satisfying performance obligations. Incurred cost represents work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Contract costs include labor, material, overhead and, when appropriate, general and administrative expenses. Revenues from maintenance contracts are structured such that the Company has the right to consideration from a customer in an amount that corresponds directly with the performance completed to date. Therefore, the Company utilizes the practical expedient in FASB ASC 606-55-255, which allows the Company to recognize revenue in the amount to which it has the right to invoice. Applying this practical expedient, the Company is not required to disclose the transaction price allocated to remaining performance obligations under these agreements. Revenues from royalty license arrangements are recognized either at contract inception when the license is transferred or when the royalty has been earned, depending on whether the contract contains fixed consideration. Revenues from stand-alone product sales are recognized at a point in time, when control of the product is transferred to the customer. Revenues from these types of contracts accounted for 7.1% and 5.0% of revenues for the quarters ended March 31, 2019 and 2018, respectively.

On March 31, 2019, the Company had $474.5 million of remaining performance obligations from construction, engineering and installation services. The Company estimates that approximately $445.1 million, or 93.8%, of the remaining performance obligations at March 31, 2019 will be realized as revenues in the next 12 months.

Contract Estimates

Accounting for long-term contracts involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, the Company estimates the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract, and recognizes that profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that sometimes span multiple years. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; the performance of subcontractors; and the availability and timing of funding from the customer.

The Company’s contracts do not typically contain variable consideration or other provisions that increase or decrease the transaction price. In rare situations where the transaction price is not fixed, the Company estimates variable consideration at the most likely amount to which it expects to be entitled. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. For royalty license agreements, the Company applies the sales-based and usage-based royalty exception and recognizes royalties at the later of: (i) when the subsequent sale or usage occurs; or (ii) the satisfaction or partial satisfaction of the performance obligation to which some or all of the sales-or usage-based royalty has been allocated. For contracts in which a portion of the transaction price is retained and paid after the good or service has been transferred to the customer, the Company does not recognize a significant financing component. The primary purpose of the retainage payment is often to provide the customer with assurance that the Company will perform its obligations under the contract, rather than to provide financing to the customer.

The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is reasonably available.

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, contract assets and contract liabilities on the Consolidated Balance Sheets. Contract assets represent work performed that could not be billed either due to contract stipulations or the required contractual documentation has not been finalized. Substantially all unbilled amounts are expected to be billed and collected within one year.

For fixed fee and time-and-materials based contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. For some royalty license arrangements, minimum amounts are billed over the license term as quarterly royalty amounts are determined. This results in contract assets as the Company recognizes revenue for the license when the license is transferred to the customer at contract inception. The Company’s contract liabilities consist of advance payments, billings in excess of revenue recognized and deferred revenue.

The Company’s contract assets and contract liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. Advance payments, billings in excess of revenue recognized and deferred revenue are each classified as current.

Net contract assets (liabilities) consisted of the following (in thousands):

	March 31,    2019(1)			December 31,   2018(2)
Contract assets – current	$	59,422		$	62,467
Contract liabilities – current	(27,060		)	(32,339		)
Net contract assets	$	32,362		$	30,128

__________________________

⁽¹⁾  Amounts exclude contract assets of $2.9 million and contract liabilities of less than $1.1 million that were classified as held for sale at March 31, 2019 (see Note 5).

⁽²⁾  Amounts exclude contract assets of $1.8 million and contract liabilities of less than $0.1 million that were classified as held for sale at December 31, 2018 (see Note 5).

Included in the change of total net contract assets was a $3.0 milliondecrease in contract assets, primarily related to the timing between work performed on open contracts and contractual billing terms, and a $5.3 milliondecrease in contract liabilities, primarily related to the timing of customer advances on certain contracts.

Substantially all of the $32.3 million and $51.6 million contract liabilities balances at December 31, 2018 and December 31, 2017, respectively, were recognized in revenues during the first quarters of 2019 and 2018, respectively.

Impairment losses recognized on receivables and contract assets were not material during the first quarters of 2019 and 2018.

Restructuring and Related Activities [Abstract]

Restructuring

RESTRUCTURING

On July 28, 2017, the Company’s board of directors approved the 2017 Restructuring. As part of the 2017 Restructuring, the Company announced plans to: (i) divest Bayou; (ii) exit all non-pipe related contract applications for the Tyfo^® system in North America; (iii) right-size the cathodic protection services operation in Canada and the CIPP businesses in Australia and Denmark; and (iv) reduce corporate and other operating costs.

During 2018, the Company’s board of directors approved additional actions with respect to the 2017 Restructuring, which included the decisions to: (i) divest the Australia and Denmark CIPP businesses; (ii) take actions to further optimize operations within North America, including measures to reduce consolidated operating costs; and (iii) divest or otherwise exit multiple additional international businesses, including: (a) the Company’s cathodic protection installation activities in the Middle East, including Corrpower; (b) United Pipeline de Mexico S.A. de C.V., the Company’s Tite Liner^® joint venture in Mexico; (c) the Company’s Tite Liner^® businesses in Brazil and Argentina; (d) Aegion South Africa; and (e) the Company’s CIPP contract installation operations in England.

Total pre-tax 2017 Restructuring and related impairment charges since inception were $142.5 million ($128.5 million post-tax) and consisted of cash charges totaling $28.9 million and non-cash charges totaling $113.6 million. Cash charges included employee severance, retention, extension of benefits, employment assistance programs and other restructuring costs associated with the restructuring efforts described above. Non-cash charges included (i) $86.4 million related to goodwill and long-lived asset impairment charges recorded in 2017 as part of exiting the non-pipe FRP contracting market in North America, and (ii) $27.2 million related to allowances for accounts receivable, write-offs of inventory and long-lived assets, impairment of definite-lived intangible assets, as well as net losses on the disposal of both domestic and international entities. The Company reduced headcount by approximately 440 employees as a result of these actions.

The Company expects to incur additional cash and non-cash charges of $12 million to $16 million during 2019. The identified charges are primarily focused in the international operations of both Infrastructure Solutions and Corrosion Protection, but will also include certain charges in Energy Services to a lesser extent. The Company expects to reduce headcount by an additional 50 employees as a result of these further actions.

During the quarters ended March 31, 2019 and 2018, the Company recorded pre-tax expenses related to the 2017 Restructuring as follows (in thousands):

Assets and Liabilities Held for Sale

ASSETS AND LIABILITIES HELD FOR SALE

During the first quarter of 2019, the Company initiated plans to sell its interests in Corrpower and Aegion South Africa. The Company is currently in discussions with third parties for each of the entities and believes that it is probable that sales of each entity will occur in the second half of 2019.

On May 14, 2018, the Company’s board of directors approved a plan to divest the assets and liabilities of Insituform Australia (see Note 1). The Company is currently in discussions with a third party and management believes that it is probable that a sale will occur in the first half of 2019.

The relevant asset and liability balances at March 31, 2019 and December 31, 2018 are accounted for as held for sale and measured at the lower of carrying value or fair value less cost to sell. No impairment charges were recorded on these assets as the net carrying value approximated or was less than management’s current expectation of fair value less cost to sell. In the event the Company is unable to sell the assets and liabilities or sells them at a price or on terms that are less favorable, or at a higher cost than currently anticipated, the Company could incur impairment charges or a loss on disposal.

The following table provides the components of assets and liabilities held for sale (in thousands):

Leases [Abstract]

Leases

LEASES

Effective January 1, 2019, the Company adopted FASB ASC 842 using the adoption-date transition provision rather than at the earliest comparative period presented in the financial statements. Therefore, the Company recognized and measured leases existing at January 1, 2019 but without retrospective application. The Company also elected the package of practical expedients not to reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs and the lessee practical expedient to combine lease and non-lease components. The Company also made a policy election to not recognize right-of-use assets and lease liabilities for short-term leases for all asset classes. The impact of FASB ASC 842 on the Consolidated Balance Sheet beginning January 1, 2019 was through the recognition of operating lease assets and corresponding operating lease liabilities of $70.5 million. No impact was recorded to the Consolidated Statement of Operations or beginning retained earnings.

The Company’s operating lease portfolio includes operational field locations, administrative offices, equipment, vehicles and information technology equipment. The majority of the Company’s leases have remaining lease terms of 1 year to 20 years, some of which include options to extend the leases for 5 years or more. Right-of-use assets are presented within “Operating lease assets” on the Consolidated Balance Sheet. The current portion of operating lease liabilities are presented within “Accrued expenses”, and the non-current portion of operating lease liabilities are presented within “Operating lease liabilities” on the Consolidated Balance Sheet.

Operating lease assets and liabilities are recognized based on the present value of lease payments over the lease term at inception. For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating leases in effect prior to January 1, 2019 were recognized at the present value of the remaining payments on the remaining lease term as of January 1, 2019. A portion of the Company’s real estate, equipment and vehicle leases is subject to periodic changes in the Consumer Price Index, LIBOR or other market index. The changes to these indexes are treated as variable lease payments and recognized in the period in which the obligation for those payments is incurred. Because most leases do not provide an explicit rate of return, the Company utilizes its incremental secured borrowing rate on a lease-by-lease basis in determining the present value of lease payments at the commencement date of the lease.

The following table presents the components of lease expense (in thousands):

	Quarter Ended March 31, 2019

Total	$	286,417	$	282,003

In October 2015, the Company entered into an amended and restated $650.0 million senior secured credit facility with a syndicate of banks. In February 2018 and December 2018, the Company amended this facility (the “amended Credit Facility”). The amended Credit Facility consists of a $275.0 millionfive-year revolving line of credit and a $308.4 millionfive-year term loan facility, each with a maturity date in February 2023.

During the first quarter of 2018, the Company paid expenses of $2.4 million associated with the amended Credit Facility, $0.9 million related to up-front lending fees and $1.5 million related to third-party arranging fees and expenses, the latter of which was recorded in “Interest expense” in the Consolidated Statement of Operations. In addition, the Company had $2.4 million in unamortized loan costs associated with the original Credit Facility, of which $0.2 million was written off and recorded in “Interest expense” in the Consolidated Statement of Operations during the first quarter of 2018.

Generally, interest is charged on the principal amounts outstanding under the amended Credit Facility at the British Bankers Association LIBOR rate plus an applicable rate ranging from 1.25% to 2.25% depending on the Company’s consolidated leverage ratio. The Company can also opt for an interest rate equal to a base rate (as defined in the credit documents) plus an applicable rate, which also is based on the Company’s consolidated leverage ratio. The applicable LIBOR borrowing rate (LIBOR plus Company’s applicable rate) as of March 31, 2019 was approximately 4.49%.

The Company’s indebtedness at March 31, 2019 consisted of $275.6 million outstanding from the term loan under the amended Credit Facility and $44.0 million on the line of credit under the amended Credit Facility. Additionally, the Company had $0.9 million of debt held by its joint ventures (representing funds loaned by its joint venture partners) listed as held for sale at March 31, 2019 related to the planned sales of Corrpower and Aegion South Africa. During the first quarter of 2019, the Company borrowed $13.0 million on the line of credit for domestic working capital needs.

As of March 31, 2019, the Company had $22.6 million in letters of credit issued and outstanding under the amended Credit Facility. Of such amount, $12.3 million was collateral for the benefit of certain of our insurance carriers and $10.3 million was for letters of credit or bank guarantees of performance or payment obligations of foreign subsidiaries.

The Company’s indebtedness at December 31, 2018 consisted of $282.2 million outstanding from the term loan under the amended Credit Facility, $31.0 million on the line of credit under the amended Credit Facility and $1.0 million of third-party notes and bank debt.

At March 31, 2019 and December 31, 2018, the estimated fair value of the Company’s long-term debt was approximately $323.8 million and $307.7 million, respectively. Fair value was estimated using market rates for debt of similar risk and maturity and a discounted cash flow model, which are based on Level 3 inputs as defined in Note 13.

In October 2015, the Company entered into an interest rate swap agreement for a notional amount of $262.5 million, which is set to expire in October 2020. The notional amount of this swap mirrors the amortization of a $262.5 million portion of the Company’s $350.0 million term loan drawn from the original Credit Facility. The swap requires the Company to make a monthly fixed rate payment of 1.46% calculated on the amortizing $262.5 million notional amount, and provides for the Company to receive a payment based upon a variable monthly LIBOR interest rate calculated on the same amortizing $262.5 million notional amount. The receipt of the monthly LIBOR-based payment offsets a variable monthly LIBOR-based interest cost on a corresponding $262.5 million portion of the Company’s term loan from the original Credit Facility. After considering the impact of the interest rate swap agreement, the effective borrowing rate on the Company’s term note as of March 31, 2019 was approximately 3.74%. This interest rate swap is used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and is accounted for as a cash flow hedge. See Note 13.

On March 12, 2018, the Company entered into an interest rate swap forward agreement that begins in October 2020 and expires in February 2023 to coincide with the amortization period of the amended Credit Facility. The swap will require the Company to make a monthly fixed rate payment of 2.937% calculated on the then amortizing $170.6 million notional amount, and provides for the Company to receive a payment based upon a variable monthly LIBOR interest rate calculated on the same amortizing $170.6 million notional amount. The receipt of the monthly LIBOR-based payment will offset the variable monthly LIBOR-based interest cost on a corresponding $170.6 million portion of the Company’s term loan from the amended Credit Facility. This interest rate swap will be used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and accounted for as a cash flow hedge. See Note 13.

The amended Credit Facility is subject to certain financial covenants, including a consolidated financial leverage ratio and consolidated fixed charge coverage ratio. Subject to the specifically defined terms and methods of calculation as set forth in the amended Credit Facility’s credit agreement, the financial covenant requirements, as of each quarterly reporting period end, are defined as follows:

• Consolidated financial leverage ratio compares consolidated funded indebtedness to amended Credit Facility defined income with a maximum amount not to exceed 3.75 to 1.00. At March 31, 2019, the Company’s consolidated financial leverage ratio was 3.23 to 1.00 and, using the amended Credit Facility defined income, the Company had the capacity to borrow up to $54.0 million of additional debt.

• Consolidated fixed charge coverage ratio compares amended Credit Facility defined income to amended Credit Facility defined fixed charges with a minimum permitted ratio of not less than 1.15 to 1.00. At March 31, 2019, the Company’s fixed charge ratio was 1.35 to 1.00.

At March 31, 2019, the Company was in compliance with all of its debt and financial covenants as required under the amended Credit Facility.

Equity [Abstract]

Stockholders' Equity and Equity Compensation

STOCKHOLDERS’ EQUITY AND EQUITY COMPENSATION

Share Repurchase Plan

In December 2018, the Company’s board of directors authorized the open market repurchase of up to two million shares of the Company’s common stock. The program did not establish a time period in which the repurchases had to be made. In December 2018, the Company amended its Credit Facility, which limits the open market share repurchases to $32.0 million for 2019. Once repurchased, the Company promptly retires such shares.

The Company is also authorized to repurchase up to $10.0 million of the Company’s common stock in each calendar year in connection with the Company’s equity compensation programs for employees. The participants in the Company’s equity plans may surrender shares of common stock in satisfaction of tax obligations arising from the vesting of restricted stock, restricted stock unit awards and performance unit awards under such plans and in connection with the exercise of stock option awards. The deemed price paid is the closing price of the Company’s common stock on the Nasdaq Global Select Market on the date that the restricted stock, restricted stock unit or performance unit vests or the shares of the Company’s common stock are surrendered in exchange for stock option exercises. With regard to stock option awards, the option holder may elect a “net, net” exercise in connection with the exercise of employee stock options such that the option holder receives a number of shares equal to the built-in gain in the option shares divided by the market price of the Company’s common stock on the date of exercise, less a number of shares equal to the taxes due upon the exercise of the option divided by the market price of the Company’s common stock on the date of exercise. The shares of common stock surrendered for taxes due on the exercise of the option are deemed repurchased by the Company.

During the first quarter of 2019, the Company acquired 622,043 shares of the Company’s common stock for $11.1 million ($17.82 average price per share) through the open market repurchase program discussed above, 152,946 shares of the Company’s common stock for $3.1 million ($20.48 average price per share) in connection with the satisfaction of tax obligations in connection with the vesting of restricted stock units and performance units, and 48,409 shares of the Company’s common stock in connection with “net, net” exercises of employee stock options. Once repurchased, the Company immediately retired all such shares.

During the first quarter of 2018, the Company acquired 353,831 shares of the Company’s common stock for $8.4 million ($23.78 average price per share) through the open market repurchase program discussed above and 217,749 shares of the Company’s common stock for $5.3 million ($24.14 average price per share) in connection with the satisfaction of tax obligations in connection with the vesting of restricted stock, restricted stock units and performance units. Once repurchased, the Company immediately retired all such shares. The Company did not acquire any of the Company’s common stock in connection with “net, net” exercises of employee stock options.

Equity-Based Compensation Plans

In April 2016, the Company’s stockholders approved the 2016 Employee Equity Incentive Plan, which was amended in 2017 by the First Amendment to the 2016 Employee Equity Incentive Plan (as amended, the “2016 Employee Plan”). In April 2018, the Company’s stockholders approved the Second Amendment to the 2016 Employee Equity Incentive Plan, which increased by 1,700,000 the number of shares of the Company’s common stock reserved and available for issuance in connection with awards issued under the 2016 Employee Plan. The 2016 Employee Plan, which replaced the 2013 Employee Equity Incentive Plan, provides for equity-based compensation awards, including restricted shares of common stock, performance awards, stock options, stock units and stock appreciation rights. The 2016 Employee Plan is administered by the Compensation Committee of the board of directors, which determines eligibility, timing, pricing, amount and other terms or conditions of awards. As of March 31, 2019, 1,944,014 shares of the Company’s common stock were available for issuance under the 2016 Employee Plan.

In April 2016, the Company’s stockholders also approved the 2016 Non-Employee Director Equity Incentive Plan (the “2016 Director Plan”), which replaced the 2011 Non-Employee Director Equity Incentive Plan. The 2016 Director Plan provides for equity-based compensation awards, including non-qualified stock options and stock units. The board of directors administers the 2016 Director Plan and has the authority to establish, amend and rescind any rules and regulations related to the 2016 Director Plan. As of March 31, 2019, 68,689 shares of the Company’s common stock were available for issuance under the 2016 Director Plan.

Stock Awards

Stock awards, which include shares of restricted stock, restricted stock units and performance stock units, are awarded from time to time to executive officers and certain key employees of the Company. Stock award compensation is recorded based on the award date fair value and charged to expense ratably through the requisite service period. The forfeiture of unvested restricted stock, restricted stock units and performance stock units causes the reversal of all previous expense to be recorded as a reduction of current period expense.

A summary of the stock award activity is as follows:

	Quarter Ended    March 31, 2019
	Stock Awards		Weighted Average Award Date Fair Value
Outstanding at December 31, 2018	1,143,205		$	23.26
Restricted stock units awarded	283,472		20.24
Performance stock units awarded	146,367		22.78
Restricted stock units distributed	(171,073	)	18.21
Performance stock units distributed	(111,155	)	25.85
Restricted stock units forfeited	(6,655	)	23.13
Performance stock units forfeited	(42,939	)	25.90
Outstanding at March 31, 2019	1,241,222		$	22.88

Expense associated with stock awards was $2.0 million and $2.1 million for the quarters ended March 31, 2019 and 2018, respectively. Unrecognized pre-tax expense of $16.7 million related to stock awards is expected to be recognized over the weighted average remaining service period of 2.96 years for awards outstanding at March 31, 2019.

Deferred Stock Unit Awards

Deferred stock units are generally awarded to directors of the Company and represent the Company’s obligation to transfer one share of the Company’s common stock to the grantee at a future date. Historically, awards were fully vested, and fully expensed, on the date of grant. Beginning in April 2019, as a result of a recent amendment of the 2016 Director Plan, the expense related to the issuance of deferred stock units is based on the award date fair value and charged to expense ratably through the requisite service period, which is generally one year. The forfeiture of unvested deferred stock units causes the reversal of all previous expense to be recorded as a reduction of current period expense.

A summary of deferred stock unit activity is as follows:

	Quarter Ended    March 31, 2019
	Deferred Stock Units		Weighted Average Award Date Fair Value
Outstanding at December 31, 2018	287,350		$	22.80
Awarded	2,891		16.69
Distributed	(9,438	)	18.69
Outstanding at March 31, 2019	280,803		$	20.83

Expense associated with deferred stock unit awards was less than $0.1 million for each of the quarters ended March 31, 2019 and 2018.

Stock Options

Stock options on the Company’s common stock were awarded from time to time to executive officers and certain key employees of the Company. Stock options granted generally had a term of seven to ten years and an exercise price equal to the market value of the underlying common stock on the date of grant. There were 52,783 stock options exercised during the quarter ended March 31, 2019 with a weighted average exercise price of $18.11 per share. There were no stock options outstanding at March 31, 2019.

The Company’s effective tax rate in the quarter ended March 31, 2019 was a benefit of 16.0% on a pre-tax loss. The effective rate was negatively impacted by valuation allowances recorded on certain net operating losses in foreign jurisdictions for which no income tax benefits are expected to be recognized.

The Company’s effective tax rate in the quarter ended March 31, 2018 was a benefit of 40.4% on a pre-tax loss. The benefit was positively impacted by a $1.5 million net tax benefit, or 60.0% benefit to the effective tax rate, related to employee share-based payments vested during the first quarter of 2018. Excluding this benefit, the Company recorded income tax expense on a pre-tax loss primarily due to valuation allowances recorded on certain net operating losses in foreign jurisdictions for which no income tax benefits are expected to be recognized.

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

Litigation

The Company is involved in certain litigation incidental to the conduct of its business and affairs. Management, after consultation with legal counsel, does not believe that the outcome of any such litigation, individually or in the aggregate, will have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows.

Purchase Commitments

The Company had no material purchase commitments at March 31, 2019.

Guarantees

The Company has many contracts that require the Company to indemnify the other party against loss from claims, including claims of patent or trademark infringement or other third-party claims for injuries, damages or losses. The Company has agreed to indemnify its surety against losses from third-party claims of subcontractors. The Company has not previously experienced material losses under these provisions and, while there can be no assurances, currently does not anticipate any future material adverse impact on its consolidated financial position, results of operations or cash flows.

The Company regularly reviews its exposure under all its engagements, including performance guarantees by contractual joint ventures and indemnification of its surety. As a result of the most recent review, the Company has determined that the risk of material loss is remote under these arrangements and has not recorded a liability for these risks at March 31, 2019 on its Consolidated Balance Sheet.

Segment Reporting [Abstract]

Segment Reporting

SEGMENT REPORTING

The Company has three operating segments, which are also its reportable segments: Infrastructure Solutions; Corrosion Protection and Energy Services. The Company’s operating segments correspond to its management organizational structure. Each operating segment has a president who reports to the Company’s chief executive officer, who is also the chief operating decision manager (“CODM”). The operating results and financial information reported by each segment are evaluated separately, regularly reviewed and used by the CODM to evaluate segment performance, allocate resources and determine management incentive compensation.

The following disaggregated financial results have been prepared using a management approach that is consistent with the basis and manner with which management internally disaggregates financial information for the purpose of making internal operating decisions. The Company evaluates performance based on stand-alone operating income (loss), which includes acquisition and divestiture expenses and restructuring charges, if applicable.

During the first quarter of 2019, the Company began reporting Corporate expenses separately rather than allocating those costs to the operating segments. The reported information for the quarter ended March 31, 2018 has been revised to conform to the current period presentation.

Financial information by segment was as follows (in thousands):

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

DERIVATIVE FINANCIAL INSTRUMENTS

As a matter of policy, the Company uses derivatives for risk management purposes, and does not use derivatives for speculative purposes. From time to time, the Company may enter into foreign currency forward contracts to hedge foreign currency cash flow transactions. For cash flow hedges, a gain or loss is recorded in the Consolidated Statements of Operations upon settlement of the hedge. All of the Company’s hedges that are designated as hedges for accounting purposes were highly effective; therefore, no notable amounts of hedge ineffectiveness were recorded in the Company’s Consolidated Statements of Operations for either the settlement of cash flow hedges or the outstanding hedged balance. At March 31, 2019, the Company’s cash flow hedges were in a net deferred loss position of $0.4 million compared to a net deferred gain position of $1.8 million at December 31, 2018. The change during the period was due to unfavorable movements in short-term interest rates relative to the hedged position. The Company presents derivative instruments in the consolidated financial statements on a gross basis. Deferred gains and losses were recorded in other non-current assets and other non-current liabilities, respectively, and other comprehensive income on the Consolidated Balance Sheets. The net periodic change of the Company’s cash flow hedges was recorded on the foreign currency translation adjustment and derivative transactions line of the Consolidated Statements of Equity.

The Company also engages in regular inter-company trade activities and receives royalty payments from certain of its wholly-owned entities, paid in local currency, rather than the Company’s functional currency, U.S. dollars. The Company utilizes foreign currency forward exchange contracts to mitigate the currency risk associated with the anticipated future payments from certain of its international entities. During the first three months of 2019 and 2018, a gain of $0.2 million and a loss of $0.1 million, respectively, were recorded upon settlement of foreign currency forward exchange contracts. Gains and losses of this nature are recorded to “Other income (expense)” in the Consolidated Statements of Operations.

In October 2015, the Company entered into an interest rate swap agreement for a notional amount of $262.5 million, which is set to expire in October 2020. The notional amount of this swap mirrored the amortization of a $262.5 million portion of the Company’s $350.0 million term loan drawn from the original Credit Facility. The swap requires the Company to make a monthly fixed rate payment of 1.46% calculated on the amortizing $262.5 million notional amount and provides for the Company to receive a payment based upon a variable monthly LIBOR interest rate calculated by amortizing the $262.5 million same notional amount. The receipt of the monthly LIBOR-based payment offsets a variable monthly LIBOR-based interest cost on a corresponding $262.5 million portion of the Company’s term loan from the original Credit Facility. This interest rate swap is used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and is accounted for as a cash flow hedge.

On March 12, 2018, the Company entered into an interest rate swap forward agreement that begins in October 2020 and expires in February 2023 to coincide with the amortization period of the amended Credit Facility. The swap will require the Company to make a monthly fixed rate payment of 2.937% calculated on the then amortizing $170.6 million notional amount, and provides for the Company to receive a payment based upon a variable monthly LIBOR interest rate calculated on the same amortizing $170.6 million notional amount. The receipt of the monthly LIBOR-based payment will offset the variable monthly LIBOR-based interest cost on a corresponding $170.6 million portion of the Company’s term loan from the amended Credit Facility. This interest rate swap will be used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and accounted for as a cash flow hedge.

The following table summarizes the Company’s derivative positions at March 31, 2019:

	Position	Notional Amount		Weighted Average Remaining Maturity In Years	Average Exchange Rate

FASB ASC 820, Fair Value Measurements (“FASB ASC 820”), defines fair value and establishes a framework for measuring and disclosing fair value instruments. The guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include:

• Level 1 – defined as quoted prices in active markets for identical instruments;

• Level 2 – defined as inputs other than quoted prices in active markets that are either directly or indirectly observable;

• Level 3 – defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

In accordance with FASB ASC 820, the Company determined that the value of all of its derivative instruments, which are measured at fair value on a recurring basis, are derived from significant observable inputs, referred to as Level 2 inputs.

The Company had no transfers between Level 1, 2 or 3 inputs during the quarter ended March 31, 2019. Certain financial instruments are required to be recorded at fair value. Changes in assumptions or estimation methods could affect the fair value estimates; however, the Company does not believe any such changes would have a material impact on its financial condition, results of operations or cash flows. Other financial instruments including cash and cash equivalents and short-term borrowings, including notes payable, are recorded at cost, which approximates fair value, which is based on Level 2 inputs as previously defined.

Taxation

Taxation

The Company provides for estimated income taxes payable or refundable on current year income tax returns as well as the estimated future tax effects attributable to temporary differences and carryforwards, based upon enacted tax laws and tax rates, and in accordance with FASB ASC 740, Income Taxes (“FASB ASC 740”). FASB ASC 740 also requires that a valuation allowance be recorded against any deferred tax assets that are not likely to be realized in the future. The determination is based on the Company’s ability to generate future taxable income and, at times, is dependent on its ability to implement strategic tax initiatives to ensure full utilization of recorded deferred tax assets. Should the Company not be able to implement the necessary tax strategies, it may need to record valuation allowances for certain deferred tax assets, including those related to foreign income tax benefits. Significant management judgment is required in determining the provision for income taxes, deferred tax assets and liabilities and any valuation allowances recorded against net deferred tax assets.

Cash, Cash Equivalents and Restricted Cash

Cash, Cash Equivalents and Restricted Cash

The Company classifies highly liquid investments with original maturities of 90 days or less as cash equivalents. Recorded book values are reasonable estimates of fair value for cash and cash equivalents.

Investments in Variable Interest Entities

Investments in Variable Interest Entities

The Company evaluates all transactions and relationships with variable interest entities (“VIE”) to determine whether the Company is the primary beneficiary of the entities in accordance with FASB ASC 810, Consolidation.

Newly Issued Accounting Pronouncements

Newly Issued Accounting Pronouncements

In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement: Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for Level 1, Level 2 and Level 3 instruments in the fair value hierarchy. The guidance is effective for the Company’s fiscal year beginning January 1, 2020, including interim periods within that fiscal year. The adoption of this standard is not expected to have a material impact on its consolidated financial statements.

In February 2018, the FASB issued Accounting Standards Update No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits a company to reclassify the income tax effects of the Tax Cuts and Jobs Act on items within accumulated other comprehensive income to retained earnings. Companies may adopt the new guidance using one of two transition methods: (i) retrospective to each period (or periods) in which the income tax effects are recognized, or (ii) at the beginning of the period of adoption. The Company adopted this standard effective January 1, 2019 and elected not to reclassify the tax effects due to the immaterial impact on the Company’s consolidated financial statements.

In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Measurement of Credit Losses on Financial Instruments, which changes the way in which entities estimate and present credit losses for most financial assets, including accounts receivable. The guidance is effective for the Company’s fiscal year beginning January 1, 2020, including interim periods within that fiscal year. Early adoption is permitted, although the Company does not intend to do so. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842), which requires lessees to present right-of-use assets and lease liabilities on the balance sheet for all leases with lease terms longer than twelve months. The Company adopted this standard, effective January 1, 2019, using the adoption-date transition provision, which recognizes and measures leases existing at January 1, 2019 but without retrospective application. See Note 6.
