Basis Of Presentation and Estimates
Basis of Presentation and Estimates	2. Basis of Presentation and Estimates The accompanying unaudited condensed consolidated financial statements reflect the results of operations, financial position, cash flows, and stockholders' equity as of and for the fiscal quarters and year-to-date periods ended July 2, 2016 and July 4, 2015, respectively. These financial statements have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") for Quarterly Reports on Form 10-Q. Accordingly, these financial statements do not include all of the information and note disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP") for annual financial statements. In the opinion of management, these financial statements reflect all adjustments of a normal, recurring nature necessary for the fair statement of CRA's results of operations, financial position, cash flows, and stockholders' equity for the interim periods presented in conformity with GAAP. Results of operations for the interim periods presented herein are not necessarily indicative of results of operations for a full year. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended January 2, 2016 included in our Annual Report on Form 10-K, filed with the SEC on March 4, 2016. The preparation of financial statements in conformity with U.S. GAAP requires management to make significant estimates and judgments that affect the reported amounts of assets and liabilities, as well as the related disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates in these condensed consolidated financial statements include, but are not limited to, allowances for accounts receivable and unbilled services, revenue recognition on fixed price contracts, depreciation of property and equipment, share-based compensation, valuation of acquired intangible assets, impairment of long lived assets, goodwill, accrued and deferred income taxes, valuation allowances on deferred tax assets, accrued compensation, accrued exit costs, and other accrued expenses. These items are monitored and analyzed by CRA for changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are recorded in the period in which they become known. CRA bases its estimates on historical experience and various other assumptions that CRA believes to be reasonable under the circumstances. Actual results may differ from those estimates if CRA's assumptions based on past experience or other assumptions do not turn out to be substantially accurate.

Principles of Consolidation
Principles of Consolidation	3. Principles of Consolidation The condensed consolidated financial statements include the accounts of CRA and its wholly owned subsidiaries. In addition, the condensed consolidated financial statements include CRA's interest in NeuCo, Inc. Effective April 13, 2016, in accordance with the asset purchase agreement, NeuCo's name was changed to GNU123 Liquidating Corporation ("GNU"). All significant intercompany accounts have been eliminated. CRA's ownership interest in GNU was 55.89% for all periods presented. GNU's financial results have been consolidated with CRA, and the portion of GNU's results allocable to its other owners is shown as "noncontrolling interest." Additionally, a member of CRA's board of directors holds a greater than 5% interest in GNU. GNU's interim reporting schedule is based on calendar month-ends, but its fiscal year end is the last Saturday of November. CRA's quarterly results could include a few days reporting lag between CRA's quarter end and the most recent financial statements available from GNU. CRA does not believe that the reporting lag will have a significant impact on CRA's consolidated income statements or financial condition. On January 8, 2015, GNU entered into an agreement to settle a note payable of approximately $981,000 in exchange for aggregate payments of $375,000. GNU recorded a gain on the extinguishment of this debt in the first quarter of fiscal 2015 of approximately $606,000. Under the settlement order, the scheduled payments were made as follows: $150,000 on January 8, 2015 and $150,000 on February 28, 2015. The final payment of $75,000 was paid on February 16, 2016. On April 13, 2016, a buyer acquired substantially all of the business assets and assumed substantially all of the liabilities of GNU for a purchase price of $1.35 million. Of this amount, $1.1 million was received at closing, with the remaining $0.25 million payable on or after April 13, 2017, subject to contingencies, as outlined in the asset purchase agreement. GNU recognized a gain on sale of its business assets of $3.8 million during the second quarter of fiscal 2016, of which $2.1 million is attributed to CRA.

Recent Accounting Standards Not Yet Adopted
Recent Accounting Standards Not Yet Adopted	4. Recent Accounting Standards Not Yet Adopted Revenue from Contracts with Customers On May 9, 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients . The relevant amendments in this ASU affect only the following aspects of Topic 606: (1) collectability criterion in Step 1, (2 ) presentation of sales taxes collected from customers in the transaction price, (3) non-cash consideration, and (4) Contract Modifications at Transition. CRA is currently evaluating the potential effects, if any, that the adoption of ASU 2016-12 may have on its financial position, results of operations, cash flows, or disclosures. On April 14, 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies two aspects of the guidance on identifying performance obligations and the licensing implementation guidance while maintaining the principles in those areas. CRA is currently evaluating the potential effects, if any, that the adoption of ASU 2016-10 may have on its financial position, results of operations, cash flows, or disclosures. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations ("ASU 2016-08"). ASU 2016-08 clarifies the provisions of principal versus agent implementation. ASU 2016-08 requires entities to determine whether they are a principal or agent for each distinct good or service they provide to customers. The new standard also clarifies the assessment necessary to determine whether the entity is acting as a principal or agent based on contract and customer. For a public entity, the amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. CRA is currently evaluating the potential effects, if any, that the adoption of ASU 2016-08 may have on its financial position, results of operations, cash flows, or disclosures. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date ("ASU 2015-14"). ASU 2015-14 defers by one year the effective date of ASU No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). The deferral results in ASU 2014-09 being effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted for interim and annual periods beginning after December 15, 2016. The main provision of ASU 2014-09 is to recognize revenue when control of the goods or services transfers to the customer, as opposed to the existing guidance of recognizing revenue when the risks and rewards transfer to the customer. CRA is currently evaluating the potential effects, if any, that the adoption of ASU 2015-14 may have on its financial position, results of operations, cash flows, or disclosures. Improvements to Employee Share-Based Payment Accounting In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (" ASU 2016-09"). ASU 2016-09 establishes new classification for excess tax benefits and deficiencies relating to share based payments. In addition, the new pronouncement allows for the option of estimating awards expected to vest or accounting for forfeitures when they occur. Cash paid by employers when withholding shares for tax withholding purposes will now be classified as a financing activity. For public business entities, the amendments in this update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. CRA is currently evaluating the potential effects, if any, that the adoption of ASU 2016-09 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 twelve 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. CRA is currently reviewing existing lease agreements and evaluating the potential effects, if any, that the adoption of ASU 2016-02 may have on its financial position, results of operations, cash flows, or disclosures. Reporting of Going-Concern Uncertainties In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern ("ASU 2014-15"). ASU 2014-15 is intended to define management's responsibility to evaluate whether there is substantial doubt about an organization's ability to continue as a going concern and provides guidance to an organization's management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures in the financial statement footnotes. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. CRA believes that the adoption of ASU 2014-15 will not have a material impact on its financial position, results of operations, cash flows, or disclosures.

Cash and Cash Equivalents	5. Cash and Cash Equivalents Cash and cash equivalents consist principally of money market funds with maturities of three months or less when purchased. As of July 2, 2016, a substantial portion of CRA's cash accounts was concentrated at a single financial institution, which potentially exposes CRA to credit risks. The financial institution has a short-term credit rating of A-2 by Standard & Poor's ratings services. CRA has not experienced any losses related to such accounts. CRA does not believe that there is significant risk of non-performance by the financial institution, and our cash on deposit is fully liquid. CRA continually monitors the credit ratings of the institution.

Fair Value of Financial Instruments
Fair Value of Financial Instruments	6. Fair Value of Financial Instruments Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1 measurement), then priority to quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market (Level 2 measurement), then the lowest priority to unobservable inputs (Level 3 measurement). The following table shows CRA's financial instruments as of July 2, 2016 and January 2, 2016 that are measured and recorded in the financial statements at fair value on a recurring basis (in thousands): July 2, 2016 Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Other Observable Inputs Significant Unobservable Inputs Level 1 Level 2 Level 3 Assets: Money market funds $ $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Assets $ $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: Contingent acquisition liability $ — $ — $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Liabilities $ — $ — $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ January 2, 2016 Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Other Observable Inputs Unobservable Inputs Level 1 Level 2 Level 3 Assets: Money market funds $ $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Assets $ $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: Contingent acquisition liability $ — $ — $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Liabilities $ — $ — $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The fair values of CRA's money market funds are based on quotes received from third-party banks. The contingent acquisition liability in the table above is for estimated future contingent consideration payments related to a prior acquisition. The fair value measure of this liability is based on significant inputs not observed in the market and thus represents a Level 3 measurement. The significant unobservable inputs used in the fair value measurements of this contingent acquisition liability are CRA's measures of the estimated payouts based on internally generated financial projections and discount rates. The fair value of the contingent acquisition liability is reassessed on a quarterly basis by CRA using additional information as it becomes available and any change in the fair value estimate is recorded in the earnings of that period.

Credit Agreement
Credit Agreement	10. Credit Agreement CRA is party to a credit agreement that provides CRA with a $125.0 million revolving credit facility and a $15 million sublimit for the issuance of letters of credit. CRA may use the proceeds of the revolving credit facility to provide working capital and for other general corporate purposes. CRA may repay any borrowings under the revolving credit facility at any time, but no later than April 24, 2018. There were no borrowings outstanding under this revolving line of credit as of July 2, 2016. As of July 2, 2016, the amount available under this revolving line of credit was reduced by certain letters of credit outstanding, which amounted to $2.1 million. Under the credit agreement, CRA must comply with various financial and non-financial covenants. Compliance with these financial covenants is tested on a quarterly basis. As of July 2, 2016, CRA was in compliance with the covenants of its credit agreement.

Revenue Recognition	11. Revenue Recognition CRA offers consulting services in two broad areas: litigation, regulatory, and financial consulting and management consulting. Together, these two service areas comprised approximately 100.0% and 99.5% of CRA's consolidated revenues for the fiscal quarter and fiscal year-to-date period ended July 2, 2016, respectively, and approximately 0.0% and 0.5% of CRA's consolidated revenues for these periods, respectively, came from its GNU subsidiary. CRA recognizes all project revenue on a gross basis based on consideration of the criteria set forth in ASC Topic 605-45, Principal Agent Considerations . The contracts that CRA enters into and operates under specify whether the engagement will be billed on a time-and-materials or a fixed-price basis. Most of CRA's revenue is derived from time-and-materials service contracts. Revenues from time-and-materials service contracts are recognized as services are provided based upon hours worked and contractually agreed-upon hourly rates, as well as indirect fees based upon hours worked. Revenues from a majority of CRA's fixed-price engagements are recognized on a proportional performance method based on the ratio of costs incurred, substantially all of which are labor-related, to the total estimated project costs. In general, project costs are classified in costs of services and are based on the direct salary of the consultants on the engagement plus all direct expenses incurred to complete the engagement, including any amounts billed to CRA by its non-employee experts. CRA's billed and unbilled receivables consist of receivables from a broad range of clients in a variety of industries located throughout the U.S. and in other countries. CRA performs a credit evaluation of its clients to minimize its collectability risk. Periodically, CRA will require advance payment from certain clients. However, CRA does not require collateral or other security. CRA maintains accounts receivable allowances for estimated losses and disputed amounts resulting from clients' failures to make required payments. CRA bases its estimates on historical collection experience, current trends, and credit policy. In determining these estimates, CRA examines historical write-offs of its receivables and reviews client accounts to identify any specific customer collection issues. If the financial condition of any of CRA's customers were to deteriorate, resulting in an impairment of their ability or intent to make payment, additional allowances may be required. A rollforward of the accounts receivable allowances is as follows (in thousands): Fiscal Year-to-Date Period Ended Fiscal Year Ended July 2, 2016 January 2, 2016 Balance at beginning of period $ $ (Decreases) increases to reserve Amounts written off ) ) Effects of foreign currency translation ) ​ ​ ​ ​ ​ ​ ​ ​ Balance at end of period $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ A rollforward of the unbilled receivables allowance is as follows (in thousands): Fiscal Year-to-Date Period Ended Fiscal Year Ended July 2, 2016 January 2, 2016 Balance at beginning of period $ $ Increases to reserves Amounts written off ) ) Effects of foreign currency translation ) — ​ ​ ​ ​ ​ ​ ​ ​ Balance at end of period $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amounts deemed uncollectible are recorded as a reduction to revenues.

Reimbursable expenses are as follows (in thousands): Quarter Ended Fiscal Year-to-Date Period Ended July 2, 2016 July 4, 2015 July 2, 2016 July 4, 2015 Reimbursable expenses $ $ $ $ CRA collects goods and services and value added taxes from customers and records these amounts on a net basis, which is within the scope of ASC Topic 605-45, Principal Agent Considerations.

Net Income per Share
Net Income per Share	12. Net Income per Share CRA calculates basic and diluted earnings per common share using the two-class method. Under the two-class method, net earnings are allocated to each class of common stock and participating security as if all of the net earnings of the period had been distributed. CRA's participating securities consist of unvested share-based payment awards that contain a nonforfeitable right to receive dividends and therefore are considered to participate in undistributed earnings with common shareholders. Basic earnings per common share excludes dilution and is calculated by dividing net earnings allocable to common shares by the weighted-average number of common share outstanding for the period. Diluted earnings per common share is calculated by dividing net earnings allocable to common shares by the weighted-average number of common shares as of the balance sheet date, as adjusted for the potential dilutive effect of non-participating share-based awards. Net earnings allocable to these participating securities were not significant for the second quarter of fiscal 2016 and fiscal 2015. The following table presents a reconciliation from net income to the net income available to common shareholders (in thousands): Quarter Ended Fiscal Year to Date Period Ended July 2, 2016 July 4, 2015 July 2, 2016 July 4, 2015 Net income, as reported $ $ $ $ Common stock equivalents: Less: net income attributable to participating shares ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income available to common shareholders $ $ $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The following is a reconciliation of basic to diluted weighted average shares of common stock outstanding (in thousands): Quarter Ended Fiscal Year to Date Period Ended July 2, 2016 July 4, 2015 July 2, 2016 July 4, 2015 Basic weighted average shares outstanding Common stock equivalents: Stock options, restricted shares, and restricted stock units ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Diluted weighted average shares outstanding ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the second quarter and fiscal year-to-date period ended July 2, 2016, the anti-dilutive share based awards that were excluded from the calculation of common stock equivalents for purposes of computing diluted weighted average shares outstanding amounted to 532,734 and 958,857 shares, respectively. For the second quarter and fiscal year-to-date period ended July 4, 2015, the anti-dilutive share based awards that were excluded from the calculation of common stock equivalent for purposes of computing diluted weighted average shares outstanding amounted to 371,421 and 381,577 shares, respectively. These share-based awards were anti-dilutive because their exercise price exceeded the average market price over the respective period. On October 23, 2014 and March 21, 2016, CRA's Board of Directors authorized the repurchase of up to $30.0 million and $20.0 million, respectively, of CRA's common stock. Repurchases under these programs are discretionary and CRA may make repurchases under any of these programs in the open market (including under any Rule 10b5-1 plan adopted by CRA) or in privately negotiated transactions, in each case in accordance with applicable insider trading and other securities laws and regulations. CRA records the retirement of its repurchased shares as a reduction to common stock. During the second quarter and first half of fiscal 2016, CRA repurchased and retired 672,795 shares, under these share repurchase programs at an average price per share of $24.09. During the second quarter and first half of fiscal 2015, CRA repurchased and retired 118,900 shares and 263,800 shares, respectively, under these share repurchase programs at an average price per share of $28.90 and $30.23, respectively. There was approximately $11.9 million available for future repurchases under these programs as of July 2, 2016.

Income Taxes
Income Taxes	13. Income Taxes CRA's effective income tax rates were 27.0% and 40.6% for the second quarters of fiscal 2016 and fiscal 2015, respectively. The effective tax rate for the second quarter of fiscal 2016 was lower than the prior year primarily due to a favorable geographical mix of earnings compared to the prior year, as well as the gain on sale of business assets of GNU of approximately $3.8 million, resulting in a disproportionately lower share of taxes as the gain was offset by net operating losses that had a full valuation allowance. The lower effective tax rate in the second quarter of fiscal 2016 was offset by the non-recurring valuation allowance benefit realized in the prior year. The effective tax rate in the second quarter of fiscal 2016 was lower than the combined Federal and state statutory tax rate due to a favorable geographical mix of earnings, as well as the sale of business assets described herein. The effective tax rate in the second quarter of fiscal 2015 was in line with the combined Federal and state statutory tax rate and included favorable rate drivers resulting from the geographical mix of earnings and the use of valuation allowances, offset by the tax treatment of contingent consideration and other permanent tax differences. Additionally, there was a discrete benefit in the quarter related to prior period true-ups primarily as a result of a statutory rate decrease for withholding taxes. CRA's effective income tax rates were 33.1% and 39.1% for the first half of fiscal 2016 and the first half of fiscal 2015, respectively. The effective tax rate for the first half of 2016 was lower than the prior year primarily due to a favorable geographical mix of earnings compared to the prior year as well as the gain on sale of business assets of GNU of approximately $3.8 million, resulting in a disproportionately lower share of taxes as the gain was offset by net operating losses that had a full valuation allowance. The lower effective tax rate in the first half of fiscal 2016 was offset by the non-recurring valuation allowance benefit realized in the prior year. The effective tax rate in the first half of fiscal 2016 was lower than the combined Federal and state statutory tax rate primarily due to a favorable geographical mix of earnings, as well as the sale of business assets described herein. The effective tax rate in the first half of fiscal 2015 was slightly lower than the combined Federal and state statutory tax rate and included favorable rates drivers resulting from the geographical mix of earnings and the use of valuation allowances, offset by the tax treatment of contingent consideration and other permanent tax differences. The valuation allowance benefit resulted from the utilization of certain historical foreign net operating losses that previously had valuation allowances. Additionally, there was a discrete benefit year-to-date related to prior period true-ups primarily as a result of a decrease in a statutory withholding tax rate, as well as the release of reserves in connection with the finalization of the tax examination in France for fiscal years 2011 and 2012, offset by a discrete provision in the first quarter of fiscal 2015 in connection with income taxes payable for a state examination that has now concluded. CRA has not provided for deferred income taxes or foreign withholding taxes on undistributed earnings from its foreign subsidiaries as of July 2, 2016 because such earnings are considered to be indefinitely reinvested. CRA does not rely on these unremitted earnings as a source of funds for its domestic business as it expects to have sufficient cash flow and availability from its U.S. revolving credit facility to fund its U.S. operational and strategic needs. If CRA were to repatriate its foreign earnings that are indefinitely reinvested, it would incur minimal additional tax expense. As of January 2, 2016, CRA had an approximate $1,265,000 balance of unrecognized tax benefits, of which, approximately $195 thousand was expected to reverse within twelve months. Of that balance, an additional $109 thousand is also expected to reverse in the foreseeable future.

Contingencies	14. Contingencies On May 20, 2016, CRA, as guarantor, and its wholly owned UK subsidiary, CRA International (UK) Limited, as tenant, entered into two agreements to lease an aggregate of 22,990 square feet of office space in London, UK. The leases commenced on May 20, 2016 and are set to expire on May 19, 2031. Following an initial rent-free period, annual fixed rent for the office space will be £0.2 million for the ground floor space, which CRA's UK subsidiary will begin paying on November 13, 2017, and £1.4 million for the fourth floor space, which CRA's UK subsidiary will begin paying on July 13, 2018. The rent under each lease is subject to increase every five years, based on rental market conditions at that time. The landlord has agreed to pay an aggregate amount of £0.1 million plus VAT to cover various costs incurred by CRA's UK subsidiary in connection with the building out of the leased properties. Subject to certain conditions, the lease for the ground floor may be terminated after 10 years. At the end of the lease terms, CRA's UK subsidiary will be responsible for returning the vacated floors to their original condition. CRA is subject to legal actions arising in the ordinary course of business. In management's opinion, CRA believes it has adequate legal defenses and/or insurance coverage with respect to the eventuality of such actions. CRA does not believe any settlement or judgment relating to any pending legal action would materially affect its financial position or results of operations.
