Recent Accounting Standards Adopted	4. Recent Accounting Standards Adopted Revenue from Contracts with Customers CRA adopted Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASC 606), which established Accounting Standards Codification ("ASC") Topic 606, on December 31, 2017, using the modified retrospective method for all contracts not completed as of the date of adoption. The reported results for fiscal 2018 reflect the application of ASC 606 guidance, while the reported results for fiscal 2017 were prepared under the guidance of ASC 605, Revenue Recognition (ASC 605). The cumulative effect of applying ASC 606 to all contracts with customers that were not completed as of December 30, 2017 amounted to $0.4 million. The cumulative effect adjustment resulted in an increase to CRA's fiscal 2018 opening balance of retained earnings of $0.4 million, net of tax. Prior periods were not retrospectively adjusted. Statement of Cash Flows (Topic 230): Restricted Cash CRA adopted ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), on January 1,2018. ASU 2016-18 amends ASC 230 to add or clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. The new standard requires cash and cash equivalents balances on the statement of cash flows to include restricted cash and cash equivalent balances. ASU 2016-18 requires a company to provide appropriate disclosures about its accounting policies pertaining to restricted cash in accordance with GAAP. Additionally, changes in restricted cash and restricted cash equivalents that result from transfers between cash, cash equivalents, and restricted cash and restricted cash equivalents are not to be presented as cash flow activities in the statement of cash flows. The adoption of ASU 2016-18 did not have a material impact on CRA’s financial position, results of operations, cash flows, or disclosures. Business Combinations (Topic 805): Clarifying the Definition of a Business CRA adopted ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), on January 1, 2018. ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist companies and other reporting organizations with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the amendments, a business is an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to investors or other owners, members, or participants. The adoption of ASU 2017-01 did not have a material impact on CRA’s financial position, results of operations, cash flows, or disclosures. Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment CRA adopted ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), on January 1, 2018. ASU 2017-04 simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. Under the amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the charge recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment charge, if applicable. The amendments also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. The adoption of ASU 2017-04 did not have a material impact on CRA’s financial position, results of operations, cash flows, or disclosures. Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting CRA adopted ASU No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”), on January 1, 2018. ASU 2017-09 updates guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. Under the amendments, an entity should account for the effects of a modification unless all the following conditions are met. First, the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification. Second, the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified. Third, the classification of the modified award as an equity instrument or a liability is the same as the classification of the original award immediately before the original award is modified. The adoption of ASU 2017-09 did not have a material impact on CRA’s financial position, results of operations, cash flows, or disclosures. Staff Accounting Bulletin No. 118 (SAB 118) On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act” (“SAB 118”), to address the application of GAAP in situations when a company does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act (the “Tax Act”). SAB 118 summarizes a three-step process to be applied at each reporting period to account for and disclose: (1) the effects of the change in tax law for which accounting is complete; (2) provisional amounts (or adjustments to provisional amounts) for the effects of the change in tax law where accounting is not complete, but a reasonable estimate has been determined; and (3) current or deferred tax amounts reflected in accordance with law prior to the enactment of the change in tax law because the accounting of the effects of the change in tax law are not complete and a reasonable estimate has not been determined, together with qualitative disclosure of the effects of the changes in tax law for which the accounting is not compete, the reason why the accounting is not complete, and the additional information that is needed to be obtained, prepared or analyzed in order to complete the accounting. Because the Tax Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretations are expected over the next 12 months, CRA considers the accounting of deferred tax remeasurements and other items to be incomplete due to the forthcoming guidance and CRA’s ongoing analysis of final year-end data and tax positions. Adjustments to these preliminary amounts identified during the measurement period, as defined, will be included as an adjustment to tax expense from continuing operations in the period in which the amounts are determined. CRA believes that it has made a good faith effort to complete the accounting under ASC 740 with respect to the Tax Act. SAB 118 provides that the measurement period is complete when a company's accounting is complete and in no circumstances, should the measurement period extend beyond one year from the enactment date of the applicable change in tax law.
