Basis of presentation

The unaudited condensed consolidated financial statements and notes herein should be read in conjunction with the audited consolidated financial statements of Great Lakes Dredge & Dock Corporation and Subsidiaries (the “Company” or “Great Lakes”) and the notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The condensed consolidated financial statements included herein have been prepared by the Company without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the SEC’s rules and regulations, although management believes that the disclosures are adequate and make the information presented not misleading. In the opinion of management, all adjustments, which are of a normal and recurring nature (except as otherwise noted), that are necessary to present fairly the Company’s financial position as of September 30, 2016, and its results of operations for the three and nine months ended September 30, 2016 and 2015 and cash flows for the nine months ended September 30, 2016 and 2015 have been included.

The components of costs of contract revenues include labor, equipment (including depreciation, maintenance, insurance and long-term rentals), subcontracts, fuel, supplies, short-term rentals and project overhead. Hourly labor is generally hired on a project-by-project basis. Costs of contract revenues vary significantly depending on the type and location of work performed and assets utilized.

The Company’s cost structure includes significant annual equipment-related costs, including depreciation, maintenance, insurance and long-term rentals. These costs have averaged approximately 21% of total costs of contract revenues over the prior three years. During the year, both equipment utilization and the timing of fixed cost expenditures fluctuate significantly. Accordingly, the Company allocates these fixed equipment costs to interim periods in proportion to revenues recognized over the year, to better match revenues and expenses. Specifically, at each interim reporting date the Company compares actual revenues earned to date on its dredging contracts to expected annual revenues and recognizes equipment costs on the same proportionate basis. In the fourth quarter, any over or under allocated equipment costs are recognized such that the expense for the year equals actual equipment costs incurred during the year.

The Company has two operating segments: dredging and environmental & infrastructure, previously referred to as environmental & remediation, which are also the Company’s two reportable segments. The Company has determined that dredging, Terra Contracting Services, LLC (“Terra”) and Great Lakes Environmental & Infrastructure, LLC (“GLEI”) are the Company’s three reporting units.

The Company performed its most recent annual test of impairment as of July 1, 2016 with no indication of impairment as of the test date. The Company will perform its next scheduled annual test of goodwill in the third quarter of 2017. Due to a decline in the overall financial performance and declining cash flows in the Terra reporting unit, the Company concluded there was a triggering event that required an interim impairment test for the reporting unit in the second quarter of 2015 and recorded a goodwill impairment charge of $2,750 during the quarter ended June 30, 2015. This impairment of goodwill is discussed in Note 6.

The condensed consolidated results of operations and comprehensive income for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year.

Recent Accounting Pronouncements

In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update No. 2016-15 (“ASU 2016-15”), Classification of Certain Cash Receipts and Cash Payments which amends FASB’s standards for reporting cash flows in general-purpose financial statements. The amendments address the diversity in practice related to the classification of certain cash receipts and payments. The guidance is effective for fiscal years beginning after December 15, 2017. The Company is currently evaluating the impact of ASU 2016-15 on its consolidated financial statements.

In March 2016, the FASB issued Accounting Standards Update No. 2016-09 (“ASU 2016-09”), Compensation – Stock Compensation (Topic 718). ASU 2016-09 identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently evaluating the impact of ASU 2016-09 on its consolidated financial statements.

In February 2016, the FASB issued Accounting Standard Update No. 2016-02 (“ASU 2016-02”), Leases (Topic 842). The Board issued this update to increase the transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods. The Company is currently evaluating the impact of ASU 2016-02 on its financial statements.

In November 2015, the FASB issued Accounting Standard Update No. 2015-17 (“ASU 2015-17”), Income Taxes: Balance Sheet Classifications of Deferred Taxes (Topic 740) which simplifies the presentation of deferred income taxes by requiring that deferred tax liabilities and assets be classified as noncurrent in the balance sheet. The update is effective for public companies for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. The guidance may be adopted prospectively or retrospectively and early adoption is permitted. As of December 31, 2015, the Company elected to early adopt this ASU 2015-17 on a prospective basis and therefore, prior years were not retrospectively adjusted.

In April 2015, the FASB issued Accounting Standard Update No. 2015-03 (“ASU 2015-03”), Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. This update is effective for fiscal years beginning after December 15, 2015, and is required to be applied retrospectively. The Company adopted this standard in the first quarter of 2016 on a retrospective basis. As a result, the Company presented $3,502 of unamortized debt issuance costs that had been included in other assets in the consolidated balance sheet as of December 31, 2015 as direct deductions from the carrying amounts of the related debt liabilities.

In May 2014, the FASB issued Accounting Standard Update No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606), which supersedes the existing revenue recognition requirements. ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 has been deferred to be effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period, which will be its first quarter of fiscal 2018. Although early adoption is permitted in fiscal 2017, the Company expects to adopt ASU 2014-09 in first quarter of 2018. The Company is currently evaluating the impact of ASU 2014-09 on its consolidated financial statements.
