Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Principles of Consolidation | Principles of Consolidation The Condensed Consolidated Financial Statements do not include footnotes and certain financial information normally presented annually under accounting principles generally accepted in the United States and, therefore, should be read in conjunction with the company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (the "2018 10-K"). Accounting measurements at interim dates inherently involve greater reliance on estimates than at year-end. The results of operations for the three and nine months ended September 30, 2019 may not necessarily be indicative of results that can be expected for the full year. The Condensed Consolidated Financial Statements included herein are unaudited; however, they contain all adjustments of a normal recurring nature which, in the opinion of management, are necessary to present fairly its consolidated financial position as of September 30, 2019 and December 31, 2018 and its consolidated results of operations and cash flows for the interim periods presented. All significant intercompany transactions of consolidated subsidiaries are eliminated. Certain amounts in 2018 have been reclassified to conform to the 2019 presentation, which includes discontinued operations and assets and liabilities held for sale, as discussed below. Management has evaluated all material events occurring subsequent to the date of the financial statements up to the filing date of this Form 10-Q. In the third quarter of 2019, management committed to a plan to sell substantially all of its government and AMECO equipment businesses, while retaining two fixed-price projects previously included in the government segment and a few small international components of AMECO. Management has concluded that these disposal groups have met the criteria to be classified as held for sale beginning in the third quarter of 2019, and as a result, the assets and liabilities of the government and AMECO businesses have been classified as held for sale on the Condensed Consolidated Balance Sheet as of September 30, 2019 and December 31, 2018. Management has also concluded that the operations of the disposal groups qualify for discontinued operations presentation because their disposal represents a strategic shift that will have a major effect on the company's financial results. Therefore, the results of the government and AMECO businesses have been presented as earnings from discontinued operations, net of tax, in the Condensed Consolidated Statement of Operations for all periods presented. See Note 21 for further discussion of the company's discontinued operations. Segment operating information for 2018 has been recast to reflect changes in the composition of the company’s reportable segments as discussed in Note 17. In the first quarter of 2019, the company adopted Accounting Standards Update (“ASU”) 2016-02 (ASC Topic 842), “Leases” using the modified retrospective method in which the new guidance was applied to leases that existed or were entered into on or after January 1, 2019. Results for the reporting period beginning on January 1, 2019 have been presented under ASC 842, while prior period amounts have not been adjusted and continue to be reported in accordance with previous guidance. See Note 3 for further discussion of the adoption and the impact on the company’s financial statements.
