The accompanying consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) have been condensed or omitted. Readers of this Quarterly Report on Form 10-Q should also read our consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 28, 2018 ( 2018 Form 10-K). In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of our consolidated financial statements at December 28, 2018 , and for the three months ended December 28, 2018 . Our interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year. Effective the beginning of fiscal first quarter 2019, the Company adopted ASC Topic 606, Revenue from Contracts with Customers , including the subsequent ASUs that amended and clarified the related guidance. The Company adopted ASC Topic 606 using the modified retrospective method, and accordingly the new guidance was applied retrospectively to contracts that were not completed or substantially completed as of September 29, 2018 (the date of initial application). See Note 13 - Revenue Accounting for Contracts and Adoption of ASC Topic 606 to the consolidated financial statements. On October 21, 2018, the Company and WorleyParsons Limited, a company incorporated in Australia (Buyer), entered into a Stock and Asset Purchase Agreement pursuant to which Buyer agreed to acquire the Companys ECR business for a purchase price of $3.3 billion consisting of (i) $2.6 billion in cash plus (ii) 58.2 million ordinary shares of the Buyer, subject to adjustments for changes in working capital and certain other items (the Transaction). The Transaction, which has been approved by the boards of directors of the Company and Buyer, is expected to close in the first half of calendar year 2019. As a result of the Transaction and all facts, management has concluded that the disposal group, which includes our entire ECR business, met the criteria to be held for sale beginning in the current fiscal quarter. Furthermore, we determined that the assets held for sale qualify for discontinued operations reporting under U.S. GAAP. Consequently, the financial results of the ECR business are reflected in our unaudited consolidated statements of earnings as discontinued operations for all periods presented. Furthermore, current and non-current assets and liabilities of the disposal group are reflected in the unaudited consolidated balance sheets for both periods presented. For further discussion see Note 7 - Discontinued Operations - Sale of Energy, Chemicals and Resources ("ECR") Business to the consolidated financial statements.
