Recent Accounting Standards Not Yet Adopted	5. Recent Accounting Standards Not Yet Adopted Securities and Exchange Commission Simplification and Update of Disclosure Requirements In August 2018, the Securities and Exchange Commission announced that it had voted to adopt amendments to certain disclosure requirements that have become duplicative, overlapping, or outdated in light of other Commission disclosure requirements, U.S. Generally Accepted Accounting Principles (GAAP), or changes in the information environment. The Commission has also referred certain disclosure requirements that overlap with, but require information incremental to, GAAP to the Financial Accounting Standards Board (FASB) for consideration for potential incorporation into GAAP. The amendments will be effective 30 days from publication in the Federal Register, or November 4, 2018. CRA has not yet determined the effects, if any, that the adoption of these amendments may have on its financial position, results of operations, cash flows, or disclosures. Fair Value Measurements (Topic 820) In August 2018, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework -- Changes to the Disclosure Requirements for Fair Value Measurement (“ASU No. 2018-13”). The ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements from ASC 820. Entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurement. The new standard is effective for interim and annual periods beginning after December 15, 2019. Entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. CRA has not yet determined the effects, if any, that the adoption of ASU 2018-10 may have on its financial position, results of operations, cash flows, or disclosures. Leases (Topic 842) In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 establishes a comprehensive new lease accounting model. The new standard clarifies the definition of a lease, requires a dual approach to lease classification similar to current lease classifications, and causes lessees to recognize leases on the balance sheet as a lease liability with a corresponding right-of-use asset for leases with a lease term of more than 12 months. The new standard is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The new standard requires a modified retrospective transition for capital or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements, but it does not require transition accounting for leases that expire prior to the date of initial application. While CRA is currently evaluating the impact of adopting ASU 2016-02, based on the lease portfolio as of September 29, 2018, CRA anticipates recording a right of use asset and a lease liability that will materially increase its assets and liabilities on the consolidated balance sheet. CRA continues to evaluate the impact on its consolidated income statement. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases (“ASU 2018-10”). ASU 2018-10 clarifies or corrects unintended application of guidance related to ASU 2016-02. The amendment affects narrow aspects of ASU 2016-02 related to (1) residual value guarantees, (2) rate implicit in the lease, (3) lessee reassessment of lease clarification, (4) lessor reassessment of lease term and purchase option, (5) variable lease payments that depend on an index or a rate, (6) investment tax credits, (7) lease term and purchase option, (8) transition guidance for amounts previously recognized in business combinations, (9) certain transition adjustments, (10) transition guidance for leases previously classified as capital leases under Topic 840, (11) transition guidance for modifications to leases previously classified as direct financing or sales-type leases under Topic 840, (12) transition guidance for sale and leaseback transactions, (13) impairment of net investment in the lease, (14) unguaranteed residual assets, (15) effect of initial direct costs on rate implicit in the lease, and (16) failed sale and leaseback transactions. The amendments in this update affect the amendments in ASU 2016-02, which are not yet effective, but for which early adoption upon issuance is permitted. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements, which creates an optional transition expedient that allows an entity to apply the transition provisions of the new standard, including its disclosure requirements, at its adoption date instead of at the beginning of the earliest comparative period presented as originally required by FASB ASU No. 2016-02. We are in the process of implementing a plan for the adoption of FASB ASU No. 2016-02. Through our implementation efforts, we have determined that we intend to elect to apply the package of practical expedients, and we do not intend to elect to apply the hindsight practical expedient. We will adopt FASB ASU No. 2016-02 on December 30, 2018 using this transition expedient. We expect that adoption of this standard will result in the recognition of a lease liability and right-of-use asset for certain operating leases that are currently not recorded on the consolidated balance sheets. While we have not yet quantified the impact of FASB ASU No. 2016-02 on our consolidated financial position or results of operations, at December 30, 2017, we were contractually obligated to make future payments of $134.0 million under our operating lease obligations in existence as of that date, primarily related to long-term facility leases. Under FASB ASU No. 2016-02, the related operating leases would potentially be required to be presented on our consolidated balance sheets. Compensation -- Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting (Topic 718) (“ASU 2018-07”). ASU 2018-07 expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments in this update specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used effectively to provide financing to the issuer or awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The new guidance is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The new guidance requires a remeasurement of nonemployee awards at fair value as of the adoption date and disclosure of the nature of and reason for the change in accounting principle and, if applicable, quantitative information about the cumulative effect of the change on retained earnings or other components of shareholders’ equity. CRA has not yet determined the effects, if any, that the adoption of ASU 2018-07 may have on its financial position, results of operations, cash flows, or disclosures.

Compensation -- Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting

In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting (Topic 718) (“ASU 2018-07”).
