Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting standard that will supersede existing revenue recognition guidance under current GAAP. The new standard is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods and services. The standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. This guidance is effective for fiscal reporting periods and interim periods within that reporting period, beginning after December 15, 2017 (first quarter of fiscal 2019 for us). We continue to evaluate the impact that this guidance will have on our consolidated financial statements. We expect to use the modified retrospective method, which will result in a cumulative effect adjustment as of the date of adoption. Due to the nature of our business, which is primarily comprised of consulting and design services, and our percentage-of-completion revenue recognition methodology, our current evaluation is that the cumulative effect adjustment and the ongoing impact to revenue recognition beginning in fiscal 2019 will be immaterial. In January 2016, the FASB issued guidance that generally requires companies to measure investments in other entities, except those accounted for under the equity method, at fair value and recognize any changes in fair value in net income. The guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2017 (first quarter of fiscal 2019 for us). We do not expect the adoption of this guidance to have an impact on our consolidated financial statements. In February 2016, the FASB issued guidance that primarily requires lessees to recognize most leases on their balance sheets but record expenses on their income statements in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. The guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2018 (first quarter of fiscal 2020 for us). Early adoption is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements. In June 2016, the FASB issued updated guidance which requires entities to estimate all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The updated guidance also expands the disclosure requirements to enable users of financial statements to understand the entity’s assumptions, models and methods for estimating expected credit losses. This guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2019 (first quarter of fiscal 2021 for us). Early adoption is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements. In August 2016, the FASB issued guidance to address eight specific cash flow issues to reduce the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2017 (first quarter of fiscal 2019 for us). Early adoption is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements. In October 2016, the FASB issued updated guidance which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This guidance is effective for fiscal reporting periods and interim reporting periods within those fiscal reporting periods, beginning after December 15, 2017 (first quarter of fiscal 2019 for us). Early adoption is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements. In November 2016, the FASB issued updated guidance which provides amendments to address the classification and presentation of changes in restricted cash in the statement of cash flows. This guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2017 (first quarter of fiscal 2019 for us). Early adoption is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements. In January 2017, the FASB issued updated guidance to simplify the test for goodwill impairment. This guidance eliminates step two from the goodwill impairment test. Under the updated guidance, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. This guidance is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019 (first quarter of fiscal 2021 for us), on a prospective basis. Earlier adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. We adopted this guidance in the first quarter of our fiscal 2018, and the adoption of this guidance had no impact on our consolidated financial statements. In May 2017, the FASB issued updated guidance to clarify when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under the updated guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award changes as a result of a change in terms or conditions. This guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2017 (first quarter of fiscal 2019 for us), on a prospective basis. Early adoption is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements. In August 2017, the FASB issued accounting guidance on hedging activities. The amendment better aligns an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. This guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2018 (first quarter of fiscal 2020 for us). Early adoption is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements. In February 2018, the FASB issued guidance on reclassification of certain tax effects from accumulated comprehensive income, which allows for a reclassification of stranded tax effects from the TCJA from accumulated other comprehensive income to retained earnings. This guidance is effective for fiscal years beginning after December 15, 2018 (first quarter of fiscal 2020 for us). We are currently evaluating the impact that this guidance will have on our consolidated financial statements.
