CRA International, Inc. ("CRA") is a worldwide leading consulting services firm that applies advanced analytic techniques and in-depth industry knowledge to complex engagements for a broad range of clients. CRA offers services in two broad areas: litigation, regulatory, and financial consulting and management consulting. CRA operates in one business segment. CRA operates its business under its registered trade name, Charles River Associates.

The accompanying unaudited condensed consolidated financial statements reflect the results of operations, financial position, cash flows, and stockholders' equity as of and for the quarters ending April 1, 2017 and April 2, 2016, 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 ("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 December 31, 2016 included in our Annual Report on Form 10-K filed with the SEC on March 15, 2017.

The preparation of financial statements in conformity with 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 consolidated 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.

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 GNU123 Liquidating Corporation ("GNU", formerly known as NeuCo Inc.). All significant intercompany transactions and 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."

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 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.

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 requires all of the tax effects related to share-based payments to be recorded through the income statement. The new pronouncement also allows for the option of estimating awards expected to vest or accounting for forfeitures when they occur. In the statement of cash flows, cash paid by employers when withholding shares for tax withholding purposes should be classified as a financing activity whereas cash flows resulting from excess tax benefits should be reported in operating activities. The amendments in this update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Accordingly, CRA adopted ASU No. 2016-09 on January 1, 2017, resulting in the recognition of a tax benefit of $0.3 million for the quarter ended April 1, 2017, in our condensed consolidated income statements. The Company had traditionally classified employee taxes paid through employer share withholdings as financing activities, therefore no further adjustment is necessary. The Company has elected to classify excess tax benefits from share-based compensation as operating activities on a prospective basis beginning in the quarter ended April 1, 2017. Additionally, the Company is not planning on making any changes in its accounting for forfeitures and will continue to estimate forfeitures based on historical experience.

In August 2015, the Financial Accounting Standards Board ("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. 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. The standard is expected to have an impact on the amount and timing of revenue recognized and the related disclosures on the Company's financial statements. The Company will adopt ASU 2014-09 during the first quarter of 2018 and the Company expects to adopt this new standard using the modified retrospective method. The Company has not completed its assessment and has not yet determined whether the impact of the adoption of this standard on its financial position, results of operations, cash flows, or disclosures will be material.

In February 2016, the FASB issued Accounting Standards Update ("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 has not yet determined the effects, if any, that the adoption of ASU 2016-02 may have on its financial position, results of operations, cash flows, or disclosures.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"). 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 the registrant 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 should not be presented as cash flow activities in the statement of cash flows. A registrant with a material balance of amounts generally described as restricted cash and restricted cash equivalents must disclose information about the nature of the restrictions. The new standard is effective for interim and annual periods beginning after December 15, 2017. CRA believes that the adoption of ASU 2016-18 will not have a material impact on its financial position, results of operations, cash flows, or disclosures.

On January 5, 2017, the FASB issued a new ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business ("ASU 2017-01"). 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. For public companies, ASU 2017-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. Early application of the amendments in ASU 2017-01 is allowed for transactions of which the acquisition date occurs before the issuance date or effective date of the amendments, only when the transaction has not been reported in financial statements that have been issued or made available for issuance; and for transactions in which a subsidiary is deconsolidated or a group of assets is derecognized that occur before the issuance date or effective date of the amendments, only when the transaction has not been reported in financial statements that have been issued or made available for issuance. CRA has not yet determined the effects, if any, that the adoption of ASU 2017-01 may have on the its financial position, results of operations, cash flows, or disclosures.

Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment

On January 26, 2017, the FASB issued a new ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). 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 loss 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 loss, if applicable. The amendment 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. For public companies, ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. CRA has not yet determined the effects, if any, that the adoption of ASU 2017-04 may have on the its financial position, results of operations, cash flows, or disclosures.

On January 30, 2017, CRA acquired substantially all of the assets and assumed certain liabilities of C1 Consulting LLC, an independent consulting firm, and its wholly own subsidiary C1 Associates (collectively, "C1") for initial consideration comprised of cash and CRA restricted common stock. The asset purchase agreement provided for additional purchase consideration to be paid for up to four years following the transaction in the form of an earnout, if specific performance targets are met. These earnout payments are payable in cash and CRA restricted common stock. The fair value of this obligation was measured as of the acquisition date and accounted for as a component of the purchase

consideration, any adjustments to this initial valuation in future accounting periods will be reported as an adjustment to net income.

C1 provides management consulting services in the life sciences industry, and has built a reputation for its specialty consulting services. Acquiring C1 will assist CRA in expanding its geographical presence in the western part of the United States and Europe, servicing CRA's existing life sciences customers more efficiently, and providing opportunities to engage with new clients in both the United States and European markets.

The acquisition has been accounted for under the purchase method of accounting, and C1's results of operations have been included in the accompanying condensed consolidated income statements from the date of acquisition. The following is a preliminary allocation of the purchase price to the estimated fair value of assets acquired and liabilities assumed. The allocation of the purchase price will be finalized as CRA receives additional information relevant to the acquisition and completes its analysis of transaction-related activities. The final purchase price allocation may be different from the preliminary estimate reported, the impact of which is not expected to be material to CRA's results of operations for fiscal 2017.

The following table shows CRA's acquired assets and liabilities assumed from the purchase of C1 Consulting (in thousands):


Assets Acquired:
Current assets:
Accounts receivable and unbilled receivables	$	3,898
Current Intangible assets		924
Other current assets		10

Total current assets		4,832

Property and equipment		206
Other non-current assets		106
Intangible assets		8,046
Goodwill		12,831

Total assets acquired	$	26,021

The intangible assets acquired are comprised of non-compete agreements and the value of customer relationships, the fair value of which was determined using the incremental income method and multi-period excess earning method, respectively. The non-compete agreements are being amortized over the stated term of five years on a straight-line basis. The customer relationships intangible is being amortized over a ten year life on a straight-line basis which approximates the expected pattern of economic benefit from this asset. The fair value of the contingent consideration was determined using a Monte Carlo simulation and will be accreted over the liabilities' measurement period to its expected future payment value on a straight-line basis. The Company is unable to estimate a range of possible outcomes for the expected future payment of the contingent consideration attributed to the limited amount of C1 GAAP historical financial results. 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.

Transaction related costs, which are principally legal and accounting service fees, amounts to $0.5 million for the fiscal quarter ended April 1, 2017.

Cash equivalents consist principally of money market funds with maturities of three months or less when purchased. As of April 1, 2017 and April 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 its cash on deposit is fully liquid. CRA continually monitors the credit ratings of the institution.

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 April 1, 2017 and December 31, 2016 that are measured and recorded in the financial statements at fair value on a recurring basis (in thousands):

The fair values of CRA's money market funds are based on quotes received from third-party banks.

The contingent acquisition liabilities in the table above are for estimated future contingent consideration payments related to prior acquisitions. The fair value measurement 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.

The following table summarizes the changes in the contingent consideration liability over the fiscal quarter ended April 1, 2017 and the fiscal year ended December 31, 2016 for the periods presented (in thousands):

Forgivable loan activity for the fiscal quarter ended April 1, 2017 and fiscal year ended December 31, 2016 is as follows (in thousands):

The changes in the carrying amount of goodwill during the fiscal quarter ended April 1, 2017, is as follows (in thousands):

Intangible assets that are separable from goodwill and have determinable useful lives are valued separately and amortized over their expected useful lives. There were no impairment losses related to intangible assets during the first quarter of fiscal 2017 or the first quarter of fiscal 2016.

The components of acquired identifiable intangible assets are as follows (in thousands):

As of April 1, 2017 and December 31, 2016, approximately $26.6 million and $53.9 million, respectively, of accrued bonuses were included above in "Compensation and related expenses".

CRA is party to a credit agreement that provides CRA with a $125.0 million revolving credit facility and a $15.0 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 $6.0 million in borrowings outstanding under this revolving credit facility as of April 1, 2017. There were no outstanding borrowings on this facility as of December 31, 2016.

As of April 1, 2017, the amount available under this revolving credit facility was reduced by certain letters of credit outstanding, which amounted to $2.2 million. Under the credit agreement, CRA must comply with various financial and non-financial covenants. Compliance with these financial covenants is tested on a fiscal quarterly basis. As of April 1, 2017 and December 31, 2016, CRA was in compliance with the covenants of its credit agreement.

CRA offers consulting services in two broad areas: litigation, regulatory, and financial consulting and management consulting. Together, these two service areas comprised 100.0% of CRA's consolidated revenues for the fiscal quarter ended April 1, 2017. 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 allowance is as follows (in thousands):

A rollforward of the unbilled receivables allowance is as follows (in thousands):

Revenues also include reimbursable expenses, which include travel and other out-of-pocket expenses, outside consultants, and other reimbursable expenses. Reimbursable expenses are as follows (in thousands):

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.

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 for 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 shares 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 first quarter of fiscal 2017 or fiscal 2016.

The following table presents a reconciliation from net income to the net income available to common shareholders (in thousands):

The following presents a reconciliation of basic to diluted weighted average shares of common stock outstanding (in thousands):

For the first quarter ended April 1, 2017, 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 8,234 shares. For the first quarter ended April 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 346,245 shares. These share-based awards each period were anti-dilutive because their exercise price exceeded the average market price over the respective period.

On March 21, 2016, CRA's Board of Directors authorized the repurchase of up to $20.0 million of CRA's common stock. Repurchases under these programs are discretionary and CRA may make such purchases 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 first quarter ended April 1, 2017 and the first quarter ended April 2, 2016, there were no shares repurchased or retired under these share repurchase programs. As of April 1, 2017, there was approximately $9.0 million available for future repurchases under these programs. See note 17 for subsequent additional repurchase authorization.

CRA's effective income tax rates were 38.6% and 46.5% for the first quarters of fiscal 2017 and fiscal 2016, respectively. The effective tax rate for the first quarter of fiscal 2017 was lower than the prior year primarily due to a more favorable geographical mix of earnings as well as the tax benefit on stock-based compensation related to the adoption of ASU 2016-09, partially offset by unfavorable discrete items in the first quarter of fiscal 2017. The effective tax rate in the first quarter of fiscal 2017 was lower than the combined federal and state statutory tax rate due to a favorable geographical mix of earnings. The effective tax rate in the first quarter of fiscal 2016 was higher than the combined federal

and state statutory tax rate primarily due to a loss in GNU for the quarter that was not benefited, as well as other permanent items, offset partially by a benefit for jurisdictional mix of earnings.

CRA has not provided for deferred income taxes or foreign withholding taxes on undistributed earnings from its foreign subsidiaries as of April 1, 2017 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.

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.

On April 12, 2017, CRA announced that Robert A. Whitman was appointed to CRA's Board of Directors effective May 3, 2017.

On April 21, 2017, CRA entered into the first amendment of the New York, New York lease for an additional 16,587 square feet of office space. The lease for the additional space will commence on April 15, 2017 and is set to expire on April 30, 2027. The annual base rent for the additional space will be approximately $1.2 million per year subject to an increase of approximately 8% after five years. The amendment includes a base rent abatement of approximately $1.2 million as well as a tenant improvement allowance of approximately $1.4 million.

On May 3, 2017, CRA's Board of Directors declared a quarterly cash dividend of $0.14 per share of CRA's common stock, payable on June 16, 2017 to shareholders of record as of May 29, 2017.

On May 3, 2017, CRA's Board of Directors authorized the repurchase of up to $20.0 million of CRA's common stock, as a result, the Company's total available authorization for share repurchases as of that date was $29.0 million.

On May 8, 2017, CRA entered into the first amendment of the Chicago, Illinois lease to extend the term of the currently leased space of 41,642 square feet, for an additional 10 years ending on July 31, 2028. Beginning on August 1, 2018, the annual base rent will be approximately $1.1 million per year, subject to annual increases of approximately 2.5% per year. The amendment includes a base rent abatement of approximately $0.9 million as well as a tenant improvement allowance of approximately $2.3 million.

ITEM 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

Except for historical facts, the statements in this quarterly report are forward-looking statements. Forward-looking statements are merely our current predictions of future events. These statements are inherently uncertain, and actual events could differ materially from our predictions. Important factors that could cause actual events to vary from our predictions include those discussed below under the heading "Risk Factors." We assume no obligation to update our forward-looking statements to reflect new information or developments. We urge readers to review carefully the risk factors described in the other documents that we file with the Securities and Exchange Commission, or SEC. You can read these documents at www.sec.gov.

Our principal Internet address is www.crai.com. Our website provides a link to a third-party website through which our annual, quarterly, and current reports, and amendments to those reports, are available free of charge. We believe these reports are made available as soon as reasonably practicable after we file them electronically with, or furnish them to, the SEC. We do not maintain or provide any information directly to the third-party website, and we do not check its accuracy.

Our website also includes information about our corporate governance practices. The Investor Relations page of our website provides a link to a web page where you can obtain a copy of our code of business conduct and ethics applicable to our principal executive officer, principal financial officer, and principal accounting officer.

The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the U.S. ("U.S. GAAP"). The preparation of these financial statements requires us 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 management 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. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from our estimates if our assumptions based on past experience or our other assumptions do not turn out to be substantially accurate.

Apart from the additional business combinations accounting policy included below, we have described our significant accounting policies in Note 1 to our consolidated financial statements included in our annual report on Form 10-K for fiscal 2016, which was filed with the SEC on March 15, 2017. We have reviewed our accounting policies, identifying those that we believe to be critical to the preparation and understanding of our consolidated financial statements in the list set forth below. See the disclosure under the heading "Critical Accounting Policies" in Item 7 of Part II of our Annual Report on Form 10-K for fiscal 2016 for a detailed description of these policies and their potential effects on our results of operations and financial condition.

We did not adopt any changes in the fiscal quarter ended April 1, 2017 that had a material effect on these critical accounting policies nor did we make any changes to our accounting policies in the fiscal quarter ended April 1, 2017 that changed these critical accounting policies.

Business Combinations. We recognize and measure identifiable assets acquired, and liabilities assumed, of our acquirees as of the acquisition date at fair value. Fair value measurements require extensive use of estimates and assumptions, including estimates of future cash flows to be generated by the acquired assets. In addition, we recognize and measure contingent consideration at fair value as of the acquisition date. Contingent consideration obligations that are classified as liabilities are remeasured at fair value each reporting period with the changes in fair value resulting from either the passage of time, revised expectations of performance, or ultimate settlement to the amount or timing of the initial measurement recognized in the consolidated statements of comprehensive income.

See Note 5 to our condensed consolidated financial statements included in this quarterly report on Form 10-Q for a discussion of recent accounting standards that we have not yet adopted. Additionally, Note 5 should be read in conjunction with the disclosure under the heading "Recent Accounting Standards" contained in Note 1 of the consolidated financial statements and the notes contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Fiscal Quarter Ended April 1, 2017 Compared to the Fiscal Quarter Ended April 2, 2016

Revenues. Revenues increased by $7.3 million, or 9.0%, to $88.2 million for the first quarter of fiscal 2017 from $80.9 million for the first quarter of fiscal 2016. Revenues increased primarily in our litigation, regulatory and business consulting practices. The increase in net revenue was a result of an increase in gross revenues of $7.7 million as compared to the first quarter of fiscal 2016, while write-offs and reserves were relatively flat compared to the first quarter of 2016. Notwithstanding a reduction in utilization to 72% for the first quarter of fiscal 2017 from 75% for the first quarter of fiscal 2016, the primary driver of revenue growth was the overall headcount growth of more than 100 consultants from the C1 acquisition and other recruiting activities in the first quarter of fiscal 2017 as compared to the first quarter of fiscal 2016.

Overall, revenues outside of the U.S. represented approximately 18% of total revenues for the first quarter of fiscal 2017 compared with approximately 22% of total revenues for the first quarter of fiscal 2016. Revenues derived from fixed-price engagements increased to 19% of total revenues for the first quarter of fiscal 2017 compared with 13% for the first quarter of fiscal 2016. These percentages of revenue derived from fixed-price engagements depend largely on the proportion of our revenues derived from our management consulting business, which typically has a higher concentration of fixed-price service contracts. The 6 percentage point increase in the first quarter of fiscal 2017 compared to the first quarter of fiscal 2016 is primarily attributable to the acquisition of C1.

Costs of Services. Costs of services increased by $7.1 million, or 12.7%, to $62.6 million for the first quarter of fiscal 2017 from $55.5 million for the first quarter of fiscal 2016. The increase in costs of services was due primarily to an increase of $2.3 million in employee compensation and fringe benefit costs attributable to salaries and benefits associated with our increased consulting headcount, an increase in incentive and retention compensation costs of $2.9 million, and an increase in forgivable loan amortization of $0.8 million. Additionally, client reimbursable expenses increased by $1.1 million in the first quarter of fiscal 2017 compared to the first quarter of fiscal 2016. As a percentage of revenues, costs of services increased to 71.0% for the first quarter of fiscal 2017 from 68.6% for the first quarter of fiscal 2016 due primarily to the previously mentioned increase in employee compensation and fringe benefit costs due to the increase in headcount, as well as the increase in incentive and retention compensation as a percentage of revenue was sourced by employees rather than consultants in the first quarter of fiscal 2017 compared to the first quarter of fiscal 2016.

Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased by $0.5 million, or 2.6%, to $18.7 million for the first quarter of fiscal 2017 from $19.2 million for the first quarter of fiscal 2016. A significant contributor to this decrease was a reduction in commissions to our nonemployee experts of $0.4 million for the first quarter of fiscal 2017 as compared to the first quarter of fiscal 2016, as a lower percentage of our revenue for the quarter was sourced by our nonemployee experts, as well as a $0.2 million decrease in rent expense as there was no double rent in the first quarter of fiscal 2017 as compared to double rent for our New York office in the first quarter of fiscal 2016. Partially offsetting this reduction were higher other professional fees of $0.6 million relative to the first quarter of fiscal 2016. Additionally, selling, general and administrative expense for GNU decreased by $0.8 million to $0.1 million in the first quarter of fiscal 2017 from $0.8 million in the first quarter of fiscal 2016, due to the cessation of its operations in April 2016.

As a percentage of revenues, selling, general and administrative expenses decreased to 21.2% for the first quarter of fiscal 2017 from 23.8% for the first quarter of fiscal 2016 due primarily to the aforementioned decrease in selling, general and administrative expenses and the increase in revenues in the first quarter of fiscal 2017 as compared with the first quarter of fiscal 2016. Commissions to our nonemployee experts decreased to 3.1% of revenues for the first quarter of fiscal 2017 compared to

3.9% of revenues for first quarter of fiscal 2016 as less revenue was sourced by nonemployee experts in the first quarter of fiscal 2017.

Provision for Income Taxes. The income tax provision was $1.8 million, and the effective tax rate was 38.6%, for the first quarter of fiscal 2017 compared to $1.9 million and 46.5% for the first quarter of fiscal 2016. The effective tax rate for the first quarter of fiscal 2017 was lower than the prior year primarily due to a more favorable geographical mix of earnings as well as the tax benefit on stock-based compensation related to the adoption of ASU 2016-09, partially offset by unfavorable discrete items in the first quarter of fiscal 2017. The effective tax rate in the first quarter of fiscal 2017 was lower than the combined Federal and state statutory tax rate due to a favorable geographical mix of earnings. The effective tax rate in the first quarter of fiscal 2016 was higher than the combined federal and state statutory tax rate primarily due to a loss in GNU for the quarter that was not benefited, as well as other permanent items, offset partially by a benefit for jurisdictional mix of earnings.

Net Income Attributable to CRA International, Inc. Net income attributable to CRA International, Inc. increased by $0.5 million to $2.9 million for the first quarter of fiscal 2017 from $2.4 million for the first quarter of fiscal 2016. The net income per diluted share was $0.33 per share for the first quarter of fiscal 2017, compared to $0.27 of net income per diluted share for the first quarter of fiscal 2016. Weighted average diluted shares outstanding decreased by approximately 306,000 shares to approximately 8,621,000 shares for the first quarter of fiscal 2017 from approximately 8,927,000 shares for the first quarter of fiscal 2016. The decrease in weighted average diluted shares outstanding was primarily due to the full benefit from the share repurchases of common stock in the remainder of fiscal 2016, offset in part by an increase as a result of shares of restricted stock and time-vesting restricted stock units that have vested or that have been issued as part of the long-term incentive plan or C1 acquisition, and stock options that have been exercised, since the first quarter of fiscal 2016.

We believe that our current cash, cash equivalents, cash generated from operations, and amounts available under our bank revolving line of credit will be sufficient to meet our anticipated working capital and capital expenditure requirements for at least the next 12 months.

General. In the fiscal quarter ended April 1, 2017, cash and cash equivalents decreased by $31.7 million. We completed the period with cash and cash equivalents of $21.8 million and working capital (defined as current assets less current liabilities) of $68.3 million. The principal driver of the reduction of cash was payment of a significant portion of our fiscal 2016 performance bonuses in the first quarter of 2017 and cash paid for the C1 acquisition.

Of the total cash and cash equivalents of $21.8 million at April 1, 2017, $3.2 million was held within the U.S. We have sufficient sources of liquidity in the U.S., including cash from operations and availability on our revolving line of credit, to fund U.S. activities. At April 1, 2017, we had outstanding borrowings on the revolving line of credit of $6.0 million, which is expected to be paid within twelve months of borrowings.

Sources and Uses of Cash. During the fiscal quarter ended April 1, 2017, net cash used in operating activities was $20.4 million. The primary factor in cash used in operations was the decrease in the "accounts payable, accrued expenses, and other liabilities" line item of the cash flow statement of $23.1 million due to the payment of a significant portion of our fiscal 2016 performance bonuses during the first quarter of fiscal 2017. Other uses of cash included a decrease in the "unbilled services" line item of the cash flow statement of $12.7 million due to the increase in unbilled amounts. Net income was $2.8 million for the fiscal quarter ended April 1, 2017. Offsetting these uses of cash was a $1.9 million increase in the "prepaid expenses and other current assets, and other assets" line item of

the cash flow statement, and the $4.1 million increase in the "accounts receivable" and "accounts receivable allowances" line item of the cash flow statement that occurred over the fiscal quarter. Cash provided by operations included cash provided by depreciation and amortization expense of $2.0 million and by share-based compensation expenses of $1.7 million. The change in forgivable loans for the period of $2.2 million was primarily driven by $3.7 million of forgivable loan amortization and repayments, net of $1.5 million of forgivable loan issuances.

During the fiscal quarter ended April 1, 2017, net cash used in investing activities was $17.0 million, which included $16.2 million in consideration relating to the C1 acquisition and $0.8 million for capital expenditures.

$5.4 million was provided by net cash from financing activities during the first quarter of fiscal 2017, primarily from the borrowings under the line of credit of $6.0 million and $1.3 million received upon the issuance of shares of common stock related to the exercise of stock options. Offsetting these increases in cash was the payment of $1.2 million cash dividend to shareholders and $0.7 million of excess tax benefits from share-based compensation.

We are party to a credit agreement that provides us with a $125.0 million revolving credit facility and a $15.0 million sublimit for the issuance of letters of credit. We may use the proceeds of the revolving credit facility to provide working capital and for other general corporate purposes. Generally, we may repay any borrowings under the revolving credit facility at any time, but must repay all borrowings no later than April 24, 2018. There was $6.0 million in outstanding balances under this revolving line of credit as of April 1, 2017.

The amount available under this revolving line of credit is reduced by certain letters of credit outstanding, which amounted to $2.2 million as of April 1, 2017.

Borrowings under the revolving credit facility bear interest at a rate per annum, at our election, of either (i) the adjusted base rate, as defined in the credit agreement, plus an applicable margin, which varies between 0.50% and 1.50% depending on our total leverage ratio as determined under the credit agreement, or (ii) the adjusted eurocurrency rate, as defined in the credit agreement, plus an applicable margin, which varies between 1.50% and 2.50% depending on our total leverage ratio. We are required to pay a fee on the unused portion of the revolving credit facility at a rate per annum that varies between 0.25% and 0.375% depending on our total leverage ratio. Borrowings under the revolving credit facility are secured by 100% of the stock of certain of our U.S. subsidiaries and 65% of the stock of certain of our foreign subsidiaries, which represent approximately $23.2 million in net assets as of April 1, 2017.

Under the credit agreement, we must comply with various financial and non-financial covenants. Compliance with these financial covenants is tested on a fiscal quarterly basis. Any indebtedness outstanding under the credit facility may become immediately due and payable upon the occurrence of stated events of default, including our failure to pay principal, interest or fees or a violation of any financial covenant. The financial covenants require us to maintain an adjusted consolidated EBITDA to consolidated interest expense ratio of more than 2.5:1.0 and to comply with a consolidated debt to adjusted consolidated EBITDA ratio of not more than 3.0:1.0. The non-financial covenant restrictions of the senior credit agreement include, but are not limited to, our ability to incur additional indebtedness, engage in acquisitions or dispositions, and enter into business combinations.

In order to attract and retain highly skilled professionals, we may issue forgivable loans or term loans to employees and non-employee experts. A portion of these loans is collateralized. The forgivable loans have terms that are generally between three and eight years. The principal amount of forgivable loans and accrued interest is forgiven by us over the term of the loans, so long as the employee or non-employee expert continues employment or affiliation with us and complies with certain contractual requirements. The expense associated with the forgiveness of the principal amount of the loans is recorded as compensation expense over the service period, which is consistent with the term of the loans.

We have entered into compensation arrangements for the payment of incentive performance awards to certain of our non-employee experts and employees if specific performance targets are met. The amounts of the awards to be paid under these compensation arrangements could fluctuate depending on future performance through the respective measurement periods. Changes in the estimated award are expensed prospectively over the remaining service period. We believe that we will have sufficient funds to satisfy any obligations related to the incentive performance awards. We expect to fund these payments, if any, from existing cash resources, cash generated from operations, or borrowings on our existing revolving credit facility.

As part of our business, we regularly evaluate opportunities to acquire other consulting firms, practices or groups or other businesses. In recent years, we have typically paid for acquisitions with cash, or a combination of cash and our common stock, and we may continue to do so in the future. To pay for an acquisition, we may use cash on hand, cash generated from our operations, borrowings under our revolving credit facility, or we may pursue other forms of financing. Our ability to secure short-term and long-term debt or equity financing in the future, including our ability to refinance our current senior loan agreement, will depend on several factors, including our future profitability, the levels of our debt and equity, restrictions under our existing revolving line of credit with our bank, and the overall credit and equity market environments. See Note 6 Business Acquisitions to the condensed consolidated financial statements to this Form 10-Q for further details of the C1 acquisition.

On March 21, 2016, our Board of Directors authorized the repurchase of up to $20.0 million of our common stock. Repurchases under these programs are discretionary and we may make such purchases under any of these programs in the open market (including under any Rule 10b5-1 plan adopted by us) or in privately negotiated transactions in accordance with applicable insider trading and other securities laws and regulations. During the fiscal quarter ended April 1, 2017, we did not repurchase or retire any shares under these programs. On May 3, 2017, our Board of Directors authorized the repurchase of up to $20.0 million of our common stock, as a result, our total available authorization for share repurchases is $29.0 million.

We will finance these programs with available cash, cash from future operations and funds from our existing revolving credit facility. We expect to continue to repurchase shares under these programs.

We anticipate paying regular quarterly dividends each year. These dividends are anticipated to be funded through cash flow from operations, available cash on hand, and/or borrowings under our revolving credit facility. Although we anticipate paying regular quarterly dividends on our common stock for the foreseeable future, the declaration of any future dividends is subject to the discretion of our board of directors.

To date, inflation has not had a material impact on our financial results. There can be no assurance, however, that inflation will not adversely affect our financial results in the future.

We anticipate that our future capital and liquidity needs will principally consist of funds required for:

The hiring of individuals to replenish and expand our employee base is an essential part of our business operations and has historically been funded principally from operations. Many of the other above activities are discretionary in nature. For example, capital expenditures can be deferred, acquisitions can be forgone, and share repurchase programs and regular dividends can be suspended. As such, our operating model provides flexibility with respect to the deployment of cash flow from operations. Given this flexibility, we believe that our cash flows from operations, supplemented by cash on hand and borrowings under our bank credit facility (as necessary), will provide adequate cash to fund our long-term cash needs from normal operations for at least the next twelve months.

Our conclusion that we will be able to fund our cash requirements by using existing capital resources and cash generated from operations does not take into account the impact of any future acquisition transactions or any unexpected significant changes in the number of employees or other expenditures that are currently not contemplated. The anticipated cash needs of our business could change significantly if we pursue and complete additional business acquisitions, if our business plans change, if economic conditions change from those currently prevailing or from those now anticipated, or if other unexpected circumstances arise that have a material effect on the cash flow or profitability of our business. Any of these events or circumstances, including any new business opportunities, could involve significant additional funding needs in excess of the identified currently available sources and could require us to raise additional debt or equity funding to meet those needs on terms that may be less favorable compared to our current sources of capital. Our ability to raise additional capital, if necessary, is subject to a variety of factors that we cannot predict with certainty, including:

Important factors that could cause our actual results to differ materially from the forward-looking statements we make in this Quarterly Report on Form 10-Q, as well as a description of material risks we face, are set forth under the heading "Risk Factors" included in Part I—Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on March 15, 2017. If any of these risks, or any risks not presently known to us or that we currently believe are not significant, develops into an actual event, then our business, financial condition, and results of operations could be adversely affected.

For information regarding our exposure to certain market risks see "Item 7A. Quantitative and Qualitative Disclosures about Market Risk," in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. This is done in order to ensure that information we are required to disclose in the reports that are filed or submitted under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Based upon that evaluation, our President and Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of April 1, 2017, due to the material weaknesses in internal control over financial reporting related to the inadequate design and execution of controls over revenue and related reserve processes, compensation-related processes, and certain non-routine technical accounting processes described in Item 9A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Notwithstanding the material weaknesses discussed, management has concluded that the condensed consolidated financial statements included in this Form 10-Q present fairly, in all material aspects, our financial position, results of operations and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States.

Under the supervision and with the participation of our management, including our President and Chief Executive Officer and Chief Financial Officer, we evaluated whether there were any changes in our internal control over financial reporting during the first quarter of fiscal 2017. Except for the ongoing remediation of the material weaknesses in internal controls over financial reporting related to the allocation of GNU's net income (loss) to noncontrolling interest and other deficiencies in the financial statement close process and the inadequate design and execution of controls over revenue and related reserve processes, compensation-related processes, and certain non-routine technical accounting processes pursuant to the plans described in Item 9A of our Annual Reports on Form 10-K for the fiscal years ended January 2, 2016 and December 31, 2016, respectively, there were no changes in our internal control over financial reporting identified in connection with the above evaluation that occurred during the first quarter of fiscal 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management has initiated a remediation plan which includes, but is not limited to, the following actions:

The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to various inherent limitations, including judgments used in decision making, assumptions about the likelihood of future events, the soundness of our systems, the possibility of human error, and the risk of fraud. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions and the risk that the degree of compliance with policies or procedures may deteriorate over time. Because of these limitations, there can be no assurance that any system of disclosure controls and procedures or internal control over financial reporting will be successful in preventing all errors or fraud or in making all material information known in a timely manner to the appropriate levels of management.

There has been no material change in any risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on March 15, 2017. See "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 for a complete description of the material risks we face.

(c) The following table provides information about our repurchases of shares of our common stock during the fiscal quarter ended April 1, 2017. During that period, we did not act in concert with any affiliate or any other person to acquire any of our common stock and, accordingly, we do not believe that purchases by any such affiliate or other person (if any) are reportable in the following table. For purposes of this table, we have divided the fiscal quarter into three periods of four weeks, four weeks, and five weeks, respectively, to coincide with our reporting periods during the first quarter of fiscal 2017.

(1): During the four weeks ended February 25, 2017 we accepted 1,782 shares of our common stock as a tax withholding from certain of our employees, in connection with the vesting of shares of restricted stock that occurred during the indicated period, pursuant to the terms of our 2006 equity incentive plan, at the average price of $36.54. During the five weeks ended April 1, 2017 we accepted 17,737 shares of our common stock as a tax withholding from certain of our employees, in connection with the vesting of shares of restricted stock and restricted stock units that occurred during the indicated period, pursuant to the terms of our 2006 equity incentive plan, at the average price per share of $35.92.
(2): On March 21, 2016, we announced that our Board of Directors approved share repurchase programs of up to $20.0 million of our common stock. We may repurchase shares under any of these programs in open market purchases (including through any Rule 10b5-1 plan adopted by us) or in privately negotiated transactions in accordance with applicable insider trading and other securities laws and regulations. We did not repurchase any shares under these programs during the fiscal quarter ended April 1, 2017. On May 3, 2017, our Board of Directors authorized the repurchase of up to$20.0 million of our common stock, as a result, our total available authorization for share repurchases is $29.0 million.
