Notes to Condensed Consolidated Financial Statements

(Unaudited)

1. Description of Business

        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 its services in two broad areas: litigation, regulatory and financial consulting and management consulting. CRA operates in one business segment, which is consulting services. CRA operates its business under its registered trade name, Charles River Associates.

2. Unaudited Interim Condensed Consolidated Financial Statements and Estimates

        The following financial statements included in this report are unaudited: the condensed consolidated income statements for the fiscal quarters and year to date periods ended June 28, 2014 and June 29, 2013, the condensed consolidated statements of comprehensive income for the fiscal quarters and year to date periods ended June 28, 2014 and June 29, 2013, the condensed consolidated balance sheet as of June 28, 2014, the condensed consolidated statements of cash flows for the fiscal year to date periods ended June 28, 2014 and June 29, 2013, and the condensed consolidated statement of shareholders' equity for the fiscal year to date period ended June 28, 2014. In the opinion of management, these statements include all adjustments necessary for a fair presentation of CRA's consolidated financial position, results of operations, and cash flows. The condensed consolidated balance sheet as of December 28, 2013 included in this report was derived from audited consolidated financial statements included in CRA's Annual Report on Form 10-K that was filed on March 13, 2014.

        The preparation of financial statements in conformity with generally accepted accounting principles in the U.S. ("U.S. GAAP") requires management to make significant estimates and judgments that affect the reported amounts of assets and liabilities, and 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 consolidated financial statements include, but are not limited to, accounts receivable allowances, 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 statement of cash flows for the fiscal year to date period ended June 29, 2013 has been adjusted to properly present payments of debt issuance costs, which were previously presented in cash used in operating activities and have been reclassified to cash used in financing activities. This revision is not material to CRA's consolidated financial statements taken as a whole.

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. ("NeuCo"). All significant intercompany accounts have been eliminated.

        CRA's ownership interest in NeuCo constitutes control under U.S. GAAP for all periods presented. Therefore, NeuCo's financial results have been consolidated with CRA and the portion of NeuCo's results allocable to its other owners is shown as "noncontrolling interest."

        NeuCo'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 NeuCo. CRA does not believe that the reporting lag will have a significant impact on CRA's consolidated income statements or financial condition.

4. Recent Accounting Standards

Accounting for Share-Based Payments

        In June 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force) ("ASU 2014-12"). ASU 2014-12 clarifies that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting. Therefore, an entity would not record compensation expense (measured as of the grant date without taking into account the effect of the performance target) related to an award for which transfer to the employee is contingent on the entity's satisfaction of a performance target until it becomes probable that the performance target will be met. No new disclosures are required under ASU 2014-12. ASU 2014-12 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. CRA believes that the adoption of ASU 2014-12 will not have a material impact on its financial position, results of operations, cash flows, or disclosures.

Revenue from Contracts with Customers

        In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). 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. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. CRA has not yet determined the effects, if any, that the adoption of ASU 2014-09 may have on its financial position, results of operations, cash flows, or disclosures.

Presentation of Unrecognized Tax Benefits

        In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11") to clarify the presentation of current and deferred income taxes on the balance sheet.

CRA International, Inc.

Notes to Condensed Consolidated Financial Statements (Continued)

(Unaudited)

4. Recent Accounting Standards (Continued)

Under ASU 2013-11, companies generally must present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, for a net operating loss carryforward, similar tax loss, or tax credit carryforward using the "net presentation" approach as a reduction of a deferred tax asset, with some allowed exceptions. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. CRA's adoption of ASU 2013-11 in the first quarter of fiscal 2014 had no impact on its financial position, results of operations, cash flows, or disclosures.

Cumulative Translation Adjustment

        In March 2013, the FASB issued ASU No. 2013-05, Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity ("ASU 2013-05"). ASU 2013-05 addresses the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. ASU 2013-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and should be applied prospectively. CRA's adoption of ASU 2013-05 in the first quarter of fiscal 2014 had no impact on its financial position, results of operations, cash flows, or disclosures.

5. Cash and Cash Equivalents

        Cash equivalents consist principally of money market funds with maturities of three months or less when purchased. As of June 28, 2014, 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 the cash on deposit is fully liquid. CRA continually monitors the credit ratings of this institution.

        The carrying amounts of these instruments classified as cash equivalents are stated at amortized cost, which approximates fair value because of their short-term maturity.

6. Prepaid Expenses and Other Current Assets, and Other Assets

        Prepaid expenses and other current assets consist of the following (in thousands):

	June 28, 2014		December 28, 2013
Term loans to employees	$	1,764	$	1,764
Other		14,011		10,011
Total	$	15,775	$	11,775

6. Prepaid Expenses and Other Current Assets, and Other Assets (Continued)

        Other assets consist of the following (in thousands):

	June 28, 2014		December 28, 2013
Forgivable loans to employees and non-employee experts	$	45,280	$	51,083
Other		2,919		3,538
Total	$	48,199	$	54,621

        In order to attract and retain highly skilled professionals, CRA may issue forgivable loans or term loans to employees and non-employee experts which are classified in "prepaid expenses and other current assets" and "other assets" within the accompanying balance sheets as of June 28, 2014 and December 28, 2013. A portion of the term loans are 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 CRA over the term of the loans, so long as the employee or non-employee expert continues employment or affiliation with CRA 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. During the second quarter of fiscal 2014, CRA issued approximately $0.7 million in forgivable loans to employees and non-employee experts for future service. As of June 28, 2014, CRA had obligations to issue approximately $4.1 million in forgivable loans to employees, future employees, and non-employee experts for future service, which are included in the $45.3 million of such loans reported as of June 28, 2014 in the table above. CRA expects that the $4.1 million in loans will be issued, and the corresponding payments will be made, before the end of the third quarter of fiscal 2014.

7. Goodwill

        In accordance with Accounting Standards Codification ("ASC") Topic 350, Intangibles—Goodwill and Other, goodwill is not subject to amortization, but is monitored at least annually for impairment, or more frequently, as necessary, if events or circumstances exist that would more likely than not reduce the fair value of the reporting unit below its carrying amount. For CRA's goodwill impairment analysis, CRA operates under one reporting unit. Under ASC Topic 350, in performing the first step of the goodwill impairment testing and measurement process, CRA compares its entity-wide estimated fair value to its net book value to identify potential impairment. Management estimates the entity-wide fair value utilizing CRA's market capitalization, plus an appropriate control premium. Market capitalization is determined by multiplying the shares outstanding on the test date by the market price of CRA's common stock on that date. CRA has utilized a control premium that considers appropriate industry, market and other pertinent factors, including indications of such premiums from data on recent acquisition transactions. If the fair value of CRA is less than its net book value, the second step is performed to determine if goodwill is impaired. If CRA determines through the impairment evaluation process that goodwill has been impaired, an impairment charge would be recorded in its consolidated income statements.

        There were no impairment losses related to goodwill during each of the fiscal year to date periods ended June 28, 2014 and June 29, 2013, respectively, as there were no events or circumstances that would more likely than not reduce CRA's fair value below its carrying amount.

7. Goodwill (Continued)

        CRA continues to monitor its market capitalization. If CRA's market capitalization, plus an estimated control premium, is below its net book value for a period considered to be other-than-temporary, it is possible that CRA may be required to record an impairment of goodwill either as a result of the annual assessment that CRA conducts in the fourth quarter of each fiscal year, or in a future quarter if events or circumstances exist that would more likely than not reduce CRA's fair value below its carrying amount. A non-cash goodwill impairment charge would have the effect of decreasing CRA's earnings in such period.

        The changes in the carrying amount of goodwill during the fiscal year to date period ended June 28, 2014, are as follows (in thousands):

	Goodwill, gross		Accumulated impairment losses			Goodwill, net
Balance at December 28, 2013	$	153,466	$	(71,893	)	$	81,573
Goodwill adjustments related to acquisitions		1,829		—			1,829
Effect of foreign currency translation		494		—			494
Balance at June 28, 2014	$	155,789	$	(71,893	)	$	83,896

9. Credit Agreement

        As of June 28, 2014, 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 loans for working capital and 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 was no amount outstanding under this revolving line of credit as of June 28, 2014.

        As of June 28, 2014, the amount available under this revolving line of credit was reduced by certain letters of credit outstanding, which amounted to $1.4 million. Borrowings under the revolving credit facility bear interest at a rate per annum 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 CRA's 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 CRA's total leverage ratio. CRA is 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 its total leverage ratio. Borrowings under the credit facility are secured by 100% of the stock of certain of CRA's U.S. subsidiaries and 65% of the stock of certain of its foreign subsidiaries, which represent approximately $7.0 million in net assets as of June 28, 2014.

        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. Any indebtedness outstanding under the credit facility may become immediately due and payable upon the occurrence of stated events of default, including CRA's failure to pay principal, interest or fees or a violation of any financial covenant. The financial covenants require CRA to maintain a consolidated interest expense to adjusted consolidated EBITDA ratio of more than 2.5 to 1.0 and to comply with a consolidated debt to adjusted consolidated EBITDA ratio of not more than 3.0 to 1.0. The non-financial covenant restrictions of the senior credit agreement include, but are not limited to, CRA's ability to incur additional indebtedness, engage in acquisitions or dispositions, and enter into business combinations. As of June 28, 2014, CRA was in compliance with the covenants of its credit agreement.

10. Revenue Recognition

        CRA derives substantially all of its revenues from the performance of professional services. CRA's revenues include projects secured by our non-employee experts as well as projects secured by our employees. 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

10. Revenue Recognition (Continued)

engagement plus all direct expenses incurred to complete the engagement, including any amounts billed to CRA by its non-employee experts.

        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):

	Quarter Ended				Fiscal Year to Date Period Ended
	June 28, 2014		June 29, 2013		June 28, 2014		June 29, 2013
Reimbursable expenses	$	8,658	$	9,750	$	17,686	$	17,408

        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.

11. Net Income per Share

        Basic net income per share represents net income divided by the weighted average shares of common stock outstanding during the period. Diluted net income per share represents net income divided by the weighted average shares of common stock and common stock equivalents, if applicable, outstanding during the period. Common stock equivalents arise from stock options and unvested shares of restricted stock, using the treasury stock method. Under the treasury stock method, the amount CRA would receive on the exercise of stock options and the vesting of shares of restricted stock, the amount of compensation cost for future service that CRA has not yet recognized, and the amount of tax benefits that would be recorded in common stock when these stock options and shares of restricted stock become deductible, are assumed to be used to repurchase shares at the average share price over the applicable fiscal period, and these repurchased shares are netted against the shares underlying these stock options and these unvested shares of restricted stock. CRA's unvested shares of restricted stock that contain rights to receive non-forfeitable dividends are considered participating securities, but net earnings available to these participating securities were not significant for the second quarter and the first half of fiscal 2014. A reconciliation of basic to diluted weighted average shares of common stock outstanding is as follows (in thousands):

	Quarter Ended				Fiscal Year to Date Period Ended
	June 28, 2014		June 29, 2013		June 28, 2014		June 29, 2013
Basic weighted average shares outstanding		9,919		10,100		9,974		10,085
Common stock equivalents:
Stock options and restricted shares		107		88		93		89
Diluted weighted average shares outstanding		10,026		10,188		10,067		10,174

        For the second quarter and fiscal year-to-date period ended June 28, 2014, certain share-based awards, which amounted to 888,746 and 1,088,180 shares, respectively, were excluded from the calculation of common stock equivalents for purposes of computing diluted weighted average shares

outstanding because they were anti-dilutive. For the second quarter and fiscal year to date period ended June 29, 2013, 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 1,065,240 and 1,103,932 shares, respectively. These share-based awards were anti-dilutive because their exercise price exceeded the average market price over the respective period.

        On August 10, 2012 and February 13, 2014, the Board of Directors authorized the repurchase of up to $5.0 million and $15.0 million, respectively, of CRA's common stock. During the second quarter of fiscal 2014, CRA repurchased and retired 157,000 shares under these share repurchase programs at an average price per share of $21.70. During the first half of fiscal 2014, CRA repurchased and retired 252,600 shares under these share repurchase programs at an average price per share of $21.91. During the first half of fiscal 2013, CRA did not repurchase and retire any shares of its common stock under these programs. There was approximately $10.9 million available for future repurchases under these programs as of June 28, 2014. CRA may repurchase shares under these programs in open market purchases or in privately negotiated transactions in accordance with applicable insider trading and other securities laws and regulations.

12. Income Taxes

        CRA's effective income tax rates were 50.0% and 59.9% for the second quarters of fiscal 2014 and fiscal 2013, respectively. The effective tax rate in the second quarter of fiscal 2014 was higher than CRA's combined Federal and state statutory tax rate primarily due to a non-cash tax expense recorded in the second quarter of fiscal 2014 to correct an error in its previously issued consolidated financial statements. During the second quarter of fiscal 2014, CRA identified the prior period error, which was related to the valuation of deferred tax assets in CRA's previously issued consolidated financial statements, concluded that this error was not material to its prior reporting periods, and recorded a non-cash tax expense of approximately $0.8 million to correct this error.

        CRA's effective income tax rates were 44.7% and 37.9% for the fiscal year to date periods ended June 28, 2014 and June 29, 2013, respectively. The effective tax rate for the fiscal year to date period ended June 28, 2014 was higher than CRA's combined Federal and state statutory tax rate primarily due to the approximately $0.8 million non-cash tax expense recorded in the second quarter of fiscal 2014 to correct the error in CRA's previously issued consolidated financial statements, described earlier in this note 12, partially offset by certain favorable tax adjustments that were treated as discrete items in the first half of fiscal 2014.

        The effective tax rate for the second quarter of fiscal 2013 was higher than CRA's combined Federal and state statutory tax rate primarily due to losses in foreign jurisdictions that provided no tax benefit. In addition, during the second quarter of fiscal 2013, CRA incurred a charge for a one-time tax adjustment of approximately $0.3 million. The effective tax rate for the fiscal year to date period ended June 29, 2013 was lower than CRA's combined Federal and state statutory tax rate primarily due to the favorable settlement of a tax matter in the first quarter of fiscal 2013, partially offset by a one-time tax adjustment recorded in the second quarter of fiscal 2013 and the effect of losses in foreign jurisdictions that provided no tax benefit in the first half of fiscal 2013.

12. Income Taxes (Continued)

        CRA has not provided for deferred income taxes or foreign withholding taxes on undistributed earnings from its foreign subsidiaries as of June 28, 2014 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. credit lines 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.

13. Restructuring Charges

        CRA did not incur any restructuring charges during the second quarter or first half of fiscal 2014. The restructuring reserve balance was as follows as of June 28, 2014 (in thousands):

	Office Vacancies
Balance at December 28, 2013	$	1,170
Amounts paid, net of amounts received, during the first half of fiscal 2014		(452	)
Adjustments during the first half of fiscal 2014		20
Balance at June 28, 2014	$	738

        On the accompanying balance sheet as of June 28, 2014, the reserve balance of $0.7 million was classified principally in "current portion of deferred rent".

        CRA did not incur any restructuring charges during the second quarter or first half of fiscal 2013. The restructuring reserve balance was as follows as of June 29, 2013 (in thousands):

	Office Vacancies			Employee Workforce Reduction			Total Restructuring
Balance at December 29, 2012	$	2,106		$	873		$	2,979
Amounts paid, net of amounts received, during the first half of fiscal 2013		(451	)		(716	)		(1,167	)
Adjustments and effect of foreign currency translation during the first half of fiscal 2013		(177	)		(144	)		(321	)
Balance at June 29, 2013	$	1,478		$	13		$	1,491

14. Compensation Arrangements

        In connection with an acquisition completed in fiscal 2013, CRA agreed to pay incentive performance awards to certain non-employee experts and employees of the acquired business, if specific performance targets are met from June 2013 through May 2017. Retention of amounts paid is contingent on the individuals' continued relationships with CRA through May 2019. CRA also has compensation arrangements with other non-employee experts. 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 awards are expensed prospectively over their remaining service period.

Critical Accounting Policies and Significant Estimates

        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, liabilities, revenue and expenses, 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, accounts receivable allowances, 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.

        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 2013. 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 2013 for a detailed description of these policies and their potential effects on our results of operations and financial condition.

Revenue recognition and accounts receivable allowances

•

Share-based compensation expense

•

Valuation of goodwill and other intangible assets

•

Accounting for income taxes

        We did not adopt any changes in the first half of fiscal 2014 that had a material effect on these critical accounting policies nor did we make any changes to our accounting policies in the first half of fiscal 2014 that changed these critical accounting policies.

Recent Accounting Standards

Quarter Ended June 28, 2014 Compared to the Quarter Ended June 29, 2013

        Revenues.    Revenues increased by $13.0 million, or 19.9%, to $78.2 million for the second quarter of fiscal 2014 from $65.2 million for the second quarter of fiscal 2013. Our revenue increase was due primarily to the momentum from the latter part of fiscal 2013 that continued into first half of fiscal 2014 compared to a slow start in the first half of fiscal 2013. Revenue increased in our litigation, regulatory, and financial consulting business and management consulting business in the second half of fiscal 2013 and into the first half of fiscal 2014, reflecting organic growth and increasing contributions from the new senior-level hires we welcomed to CRA during the first quarter of fiscal 2013. Utilization increased to 78% for the second quarter of fiscal 2014 from 67% for the second quarter of fiscal 2013. NeuCo had an increase in revenue of approximately $0.2 million in the second quarter of fiscal 2014 as compared with the second quarter of fiscal 2013. A decrease in client reimbursable expenses, which are

18

pass-through expenses that carry little to no margin, partially offset the increased revenue in the second quarter of fiscal 2014 as compared to the second quarter of fiscal 2013.

        Overall, revenues outside of the U.S. represented approximately 21% of total revenues for the second quarter of fiscal 2014 and the second quarter of fiscal 2013. Revenues derived from fixed-price engagements increased to 18% of total revenues for the second quarter of fiscal 2014 compared with 14% for the second quarter of fiscal 2013. This increase was due primarily to the increase in the percentage of our revenue related to our management consulting business as the management consulting business typically has a higher concentration of fixed-price service contracts.

        Costs of Services.    Costs of services increased by $7.6 million, or 16.9%, to $52.7 million for the second quarter of fiscal 2014 from $45.0 million for the second quarter of fiscal 2013. The increase in costs of services was due primarily to an increase in incentive compensation expense for our employee consultants, principally as a result of an increase in profitability, partially offset by a decrease of $1.1 million in client reimbursable expenses for the second quarter of fiscal 2014 as compared to the second quarter of fiscal 2013. As a percentage of revenues, costs of services decreased to 67.4% for the second quarter of fiscal 2014 from 69.1% for the second quarter of fiscal 2013 due primarily to the increase in revenues outpacing the increase in incentive compensation expense for our employee consultants in the second quarter of fiscal 2014 as compared with the second quarter of fiscal 2013.

        Selling, General and Administrative Expenses.    Selling, general and administrative expenses increased by $2.1 million, or 13.5%, to $17.5 million for the second quarter of fiscal 2014 from $15.4 million for the second quarter of fiscal 2013. The primary contributors to this increase were increased compensation expense and increased commissions to our nonemployee experts for the second quarter of fiscal 2014 as compared to the second quarter of fiscal 2013.

        As a percentage of revenues, selling, general and administrative expenses decreased to 22.3% for the second quarter of fiscal 2014 from 23.6% for the second quarter of fiscal 2013 due primarily to the increase in revenues outpacing the increased compensation expense in the second quarter of fiscal 2014 as compared with the second quarter of fiscal 2013, except that commissions to our nonemployee experts increased to 3.5% of revenues for the second quarter of fiscal 2014 compared to 3.0% of revenues for the second quarter of fiscal 2013.

        Other Income (Expense), Net.    Other income (expense), net changed by $423,000 to expense of $71,000 for the second quarter of fiscal 2014 from income of $352,000 for the second quarter of fiscal 2013. Other income (expense), net consists primarily of foreign currency exchange transaction gains and losses. The multi-currency credit facility we entered into on April 24, 2013 allows us to minimize such foreign exchange exposures. We continue to manage our foreign currency exchange exposure through frequent settling of intercompany account balances and by self-hedging movements in exchange rates between the value of the dollar and foreign currencies including the Euro and the British Pound.

        Provision for Income Taxes.    The income tax provision was $3.2 million, and the effective tax rate was 50.0%, for the second quarter of fiscal 2014 compared to $2.0 million and 59.9% for the second quarter of fiscal 2013. The effective tax rate in the second quarter of fiscal 2014 was higher than our combined Federal and state statutory tax rate primarily due to a non-cash tax expense recorded in the second quarter of fiscal 2014 to correct an error in our previously issued consolidated financial statements. During the second quarter of fiscal 2014, we identified the prior period error, which was related to the valuation of deferred tax assets in our previously issued consolidated financial statements, concluded that this error was not material to our prior reporting periods, and recorded a non-cash tax expense of approximately $0.8 million to correct it.

        Our effective tax rate in the second quarter of fiscal 2013 was higher than our combined Federal and state statutory tax rate primarily due to losses in foreign jurisdictions that provided no tax benefit.

19

In addition, during the second quarter of fiscal 2013, we incurred a charge for a one-time tax adjustment of $0.3 million.

        Net Loss Attributable to Noncontrolling Interest, Net of Tax.    Our ownership interest in NeuCo constitutes control under U.S GAAP. As a result, NeuCo's financial results are consolidated with ours, and allocations of the noncontrolling interest's share of NeuCo's net income result in deductions to our net income, while allocations of the noncontrolling interest's share of NeuCo's net loss result in additions to our net income. Our ownership interest in NeuCo is 55.89%. The results of operations of NeuCo allocable to its other owners was a net loss of $21,000 for the second quarter of fiscal 2014 and a net loss of $58,000 for the second quarter of fiscal 2013.

        Net Income Attributable to CRA International, Inc.    Net income attributable to CRA International, Inc. increased by $1.8 million to net income of $3.2 million for the second quarter of fiscal 2014 from net income of $1.4 million for the second quarter of fiscal 2013. The net income per diluted share was $0.32 per share for the second quarter of fiscal 2014, compared to $0.14 of net income per diluted share for the second quarter of fiscal 2013. Diluted weighted average shares outstanding decreased by approximately 162,000 shares to approximately 10,026,000 shares for the second quarter of fiscal 2014 from approximately 10,188,000 shares for the second quarter of fiscal 2013. The decrease in diluted weighted average shares outstanding was primarily due to repurchases of common stock since the second quarter of fiscal 2013, offset in part by an increase as a result of shares of restricted stock that have vested or that have been issued since the second quarter of fiscal 2013.

Fiscal Year to Date Period Ended June 28, 2014 Compared to the Fiscal Year to Date Period Ended June 29, 2013

        Revenues.    Revenues increased by $26.1 million, or 20.3%, to $154.4 million for the fiscal year to date period ended June 28, 2014 from $128.3 million for the fiscal year to date period ended June 29, 2013. Our revenue increase was due primarily to the momentum from the latter part of fiscal 2013 that continued into the first half of fiscal 2014 compared to a slow start in the first half of fiscal 2013. Revenue increased in our litigation, regulatory, and financial consulting business and management consulting business in the second half of fiscal 2013 and into the first half of fiscal 2014, reflecting organic growth and increasing contributions from the new senior-level hires we welcomed to CRA during the first quarter of fiscal 2013. Utilization increased to 78% for the first half of fiscal 2014 from 67% for the first half of fiscal 2013. NeuCo had an increase in revenues of $0.3 million in the first half of fiscal 2014 as compared to the first half of fiscal 2013.

        Overall, revenues outside of the U.S. represented approximately 23% of total revenues for each the first half of fiscal 2014 and the first half of fiscal 2013. Revenues derived from fixed-price engagements increased to 15% of total revenues for the fiscal year to date period ended June 28, 2014 compared with 14% for the fiscal year to date period ended June 29, 2013. This increase was due primarily to the increase in the percentage of our revenue related to our management consulting business as the management consulting business typically has a higher concentration of fixed-price service contracts.

        Costs of Services.    Costs of services increased $17.5 million, or 20.1%, to $104.5 million for the fiscal year to date period ended June 28, 2014 from $87.1 million for the fiscal year to date period ended June 29, 2013. The increase in costs of services was due primarily to an increase in incentive compensation expense for our employee consultants, principally as a result of an increase in profitability, and an increase of $0.9 million in forgivable loan amortization. As is common in our industry, we have issued forgivable loans to attract and retain certain significant revenue-producing employees and non-employee experts. We issued $5.7 million and $38.0 million of forgivable loans in the first half of fiscal 2014 and the first half of fiscal 2013, respectively. Costs of services also had an increase of $0.3 million in client reimbursable expenses for the first half of fiscal 2014 as compared to

20

the first half of fiscal 2013. As a percentage of revenues, costs of services decreased to 67.7% for the first half of fiscal 2014 from 67.8% for the first half of fiscal 2013 due primarily to the increase in revenues outpacing the increases in costs of services in the first half of fiscal 2014 as compared with the first half of fiscal 2013.

        Selling, General and Administrative Expenses.    Selling, general and administrative expenses increased by $3.4 million, or 11.0%, to $34.6 million for the fiscal year to date period ended June 28, 2014 from $31.2 million for the fiscal year to date period ended June 29, 2013. The primary contributors to this increase were increased compensation expense, increased commissions to our nonemployee experts, increased rent and office operating expenses, and increased professional fees in the first half of fiscal 2014 as compared to the first half of fiscal 2013.

        As a percentage of revenues, selling, general and administrative expenses decreased to 22.4% for the first half of fiscal 2014 from 24.3% for first half of fiscal 2013 due primarily to the increase in revenues outpacing the increased compensation expense, commissions to our nonemployee experts, rent and office operating expenses, and professional fees in the first half of fiscal 2014 as compared with the first half of fiscal 2013. Commissions to our nonemployee experts decreased to 3.1% of revenues for the first half of fiscal 2014 compared to 3.2% of revenues for first half of fiscal 2013.

        Other Income (Expense) Net.    Other expense, net increased by $152,000 to $191,000 for the fiscal year to date period ended June 28, 2014 as compared to $39,000 for the fiscal year to date period ended June 29, 2013. Other income (expense), net consists primarily of foreign currency exchange transaction gains and losses. The multi-currency credit facility we entered into on April 24, 2013 allows us to minimize such foreign exchange exposures. We continue to manage our foreign currency exchange exposure through frequent settling of intercompany account balances and by self-hedging movements in exchange rates between the value of the dollar and foreign currencies including the Euro and the British Pound.

        Provision for Income Taxes.    For the fiscal year to date period ended June 28, 2014 our income tax provision was $5.2 million, and the effective tax rate was 44.7%, compared to a provision of $2.6 million and an effective tax rate of 37.9% for the fiscal year to date period ended June 29, 2013. The effective tax rate in the first half of fiscal 2014 was higher than our combined Federal and state statutory tax rate primarily due to a non-cash tax expense recorded in the second quarter of fiscal 2014 to correct an error in our previously issued consolidated financial statements, partially offset by certain favorable tax adjustments that were treated as discrete items in the first half of fiscal 2014. During the second quarter of fiscal 2014, we identified the prior period error, which was related to the valuation of deferred tax assets in our previously issued consolidated financial statements, concluded that this error was not material to our prior reporting periods, and recorded a non-cash tax expense of approximately $0.8 million to correct it.

        Our effective tax rate for the fiscal year to date period ended June 29, 2013 was lower than our combined Federal and state statutory tax rate primarily due to the favorable settlement of a tax matter in the first quarter of fiscal 2013, partially offset by a one-time tax adjustment recorded in the second quarter of fiscal 2013 and the effect of losses in foreign jurisdictions that provided no tax benefit in the first half of fiscal 2013.

        Net Loss Attributable to Noncontrolling Interest, Net of Tax.    Our ownership interest in NeuCo constitutes control under U.S. GAAP. As a result, NeuCo's financial results are consolidated with ours and allocations of the noncontrolling interest's share of NeuCo's net income result in deductions to our net income, while allocations of the noncontrolling interest's share of NeuCo's net loss result in additions to our net income. Our ownership interest in NeuCo is 55.89%. The results of operations of NeuCo allocable to its other owners was a net loss of $123,000 for the fiscal year to date period ended June 28, 2014 and a net loss of $192,000 for the fiscal year to date period ended June 29, 2013.

21

        Net Income Attributable to CRA International, Inc.    Net income attributable to CRA International, Inc. increased by $2.2 million to net income of $6.6 million for the fiscal year to date period ended June 28, 2014 from net income of $4.4 million for the fiscal year to date period ended June 29, 2013. The diluted net income per share was $0.66 per share for the fiscal year to date period ended June 28, 2014, compared to net income per share of $0.43 per share for the fiscal year to date period ended June 29, 2013. Diluted weighted average shares outstanding decreased by approximately 107,000 shares to approximately 10,067,000 shares for the fiscal year to date period ended June 28, 2014 from approximately 10,174,000 shares for the fiscal year to date period ended June 29, 2013. The decrease in diluted weighted average shares outstanding was primarily due to repurchases of common stock, offset in part by an increase as a result of shares of restricted stock that have vested or that have been issued since June 29, 2013.

Liquidity and Capital Resources

Fiscal Year to Date Period Ended June 28, 2014

        We believe that current cash, cash equivalents, cash generated from operations, and amounts available under our bank 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 first half of fiscal 2014, cash and cash equivalents decreased by $23.6 million. We completed the period with cash and cash equivalents of $27.6 million and working capital (defined as current assets less current liabilities) of $84.5 million. The principal drivers of the reduction in cash were the payment of the majority of our fiscal 2013 performance bonuses in the first quarter of fiscal 2014, the increase in days sales outstanding from 94 days at the end of fiscal 2013 to 108 days at the end of the second quarter of fiscal 2014, and the repurchase and retirement of 252,600 shares of our common stock during the first half of fiscal 2014.

        Of the total cash and cash equivalents of $27.6 million at June 28, 2014, $18.9 million was held within the U.S. We have sufficient sources of cash in the U.S. to fund U.S. cash requirements without the need to repatriate any funds.

        As of June 28, 2014, a substantial portion of our cash accounts was concentrated at a single financial institution, which potentially exposes us to credit risks. The financial institution has a short-term credit rating of A-2 by Standard & Poor's ratings services. We have not experienced any losses related to such accounts. We do not believe that there is significant risk of non-performance by the financial institution, and our cash on deposit at this financial institution is fully liquid. We continually monitor the credit ratings of such institution. A change in the credit worthiness of this financial institution could materially affect our liquidity and working capital.

        Sources and Uses of Cash.    During the first half of fiscal 2014, net cash used in operating activities was $15.2 million. The primary factor in cash used in operations was the decrease in "accounts payable, accrued expenses, and other liabilities" of $18.5 million due to the payment of the majority of our fiscal 2013 performance bonuses during the first quarter of fiscal 2014. Other uses of cash included a $6.5 million net unfavorable movement in "accounts receivable" and "accounts receivable allowances" and an unfavorable movement of $3.5 million in "unbilled services". Sources of cash included a $1.7 million favorable movement in "prepaid expenses and other assets". Cash provided by operations also included net income of $6.5 million, non-cash charges for depreciation and amortization expense of $3.1 million, share-based compensation expense of $2.6 million, and deferred income tax provision of $0.9 million, partially offset by decreased "deferred rent" of $1.5 million.

        During the first quarter of fiscal 2014, net cash used by investing activities was $2.9 million, which included $1.5 million of net acquisition consideration payments and $1.4 million for capital expenditures.

22

        We used $5.5 million of net cash in financing activities during the first half of fiscal 2014, primarily for the repurchase and retirement of our common stock of $5.4 million and the redemption of $0.1 million in vested employee restricted shares for tax withholdings.

Indebtedness

        As of June 28, 2014, we are party to a credit agreement that provides us with a $125.0 million revolving credit facility and a $15 million sublimit for the issuance of letters of credit. We may use the proceeds of the revolving credit loans 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 were no amounts outstanding under this revolving line of credit as of June 28, 2014.

        The amount available under this revolving line of credit is reduced by certain letters of credit outstanding, which amounted to $1.4 million as of June 28, 2014.

        Borrowings under the revolving credit facility bear interest at a rate per annum 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 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 $7.0 million in net assets as of June 28, 2014.

        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 a consolidated interest expense to adjusted consolidated EBITDA ratio of more than 2.5 to 1.0 and to comply with a consolidated debt to adjusted consolidated EBITDA ratio of not more than 3.0 to 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.

Forgivable Loans and Term Loans

        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 the term loans are 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. During the second quarter and first half of fiscal 2014, we issued approximately $0.7 million and $5.7 million, respectively, in forgivable loans to employees and non-employee experts for future service. As of June 28, 2014, we had obligations to issue approximately $4.1 million in forgivable loans to employees, future employees and non-employee experts for future service. We expect that the $4.1 million in loans will be issued, and the corresponding payments will be made, before the end of the third quarter of fiscal 2014.

23

Compensation Arrangements

        In connection with an acquisition completed in fiscal 2013, we agreed to pay incentive performance awards to certain non-employee experts and employees of the acquired business, if specific performance targets are met from June 2013 through May 2017. Retention of amounts paid is contingent on the individuals' continued relationships with us through May 2019. The amount of the award could fluctuate depending on future performance through May 2017. We also have compensation arrangements with other non-employee experts. 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 financing transactions.

Business Acquisitions

        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 line of credit with our bank, and the overall credit and equity market environments.

Share Repurchases

        On August 10, 2012 and February 13, 2014, our Board of Directors authorized the repurchase of up to $5.0 million and $15.0 million, respectively, of our common stock. During the second quarter of fiscal 2014 and first half of fiscal 2014, we repurchased and retired 157,000 shares and 252,600 shares of our common stock under these programs at an average price per share of $21.70 and $21.91, respectively. Approximately $10.9 million was available for future repurchases under these programs as of June 28, 2014. We will finance these programs with available cash and cash from future operations. We may repurchase shares under these programs in open market purchases or in privately negotiated transactions in accordance with applicable insider trading and other securities laws and regulations. We expect to continue to repurchase shares under these programs.

Factors Affecting Future Performance

        Part II, Item 1A of this quarterly report sets forth risks and uncertainties that could cause actual results to differ materially from the results contemplated by the forward-looking statements contained in this quarterly report. 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.

ITEM 3.    Quantitative and Qualitative Disclosures About Market Risk

Foreign Exchange Risk

        The majority of our operations are based in the U.S., and accordingly, the majority of our transactions are denominated in U.S. Dollars. However, we have foreign-based operations where transactions are denominated in foreign currencies and are subject to market risk with respect to fluctuations in the relative value of foreign currencies. Our primary foreign currency exposures relate to

24

our short-term intercompany balances with our foreign subsidiaries and accounts receivable and cash valued in the United Kingdom in U.S. Dollars or Euros. Our primary foreign subsidiaries have functional currencies denominated in the British Pound and the Euro, and foreign denominated assets and liabilities are re-measured each reporting period with any exchange gains and losses recorded in our consolidated income statements. We continue to manage our foreign currency exchange exposure through frequent settling of intercompany account balances and by self-hedging movements in exchange rates between the value of the U.S. Dollar and foreign currencies and the Euro and the British Pound. Holding all other variables constant, fluctuations in foreign exchange rates may impact reported revenues and expenses significantly, based on currency exposures at June 28, 2014. A hypothetical 10% movement in foreign exchange rates would have affected our income before provision for income taxes for the second quarter of fiscal 2014 by approximately $0.2 million. However, actual gains and losses in the future could differ materially from this analysis based on the timing and amount of both foreign currency exchange rate movements and our actual exposure.

        From time to time, we may use derivative instruments to manage the risk of exchange rate fluctuations. However, at June 28, 2014, we had no outstanding derivative instruments. We do not use derivative instruments for trading or speculative purposes.

Interest Rate Risk

        We maintain an investment portfolio consisting mainly of money market funds with maturities of three months or less when purchased. These held-to-maturity securities are subject to interest rate risk. However, a hypothetical change in the interest rate of 10% would not have a material impact to the fair values of these securities at June 28, 2014 primarily due to their short maturity.

ITEM 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

        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 to provide reasonable assurance that we record, process, summarize and report the information we must disclose in reports that we file or submit under the Securities Exchange Act of 1934, as amended, 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 June 28, 2014, due to the material weakness in internal controls over our income tax accounting and reporting for income taxes described in Item 9A of our Annual Report on Form 10-K for the fiscal year ended December 28, 2013.

        Notwithstanding the material weakness, management has concluded that the 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.

Evaluation of Changes in Internal Control over Financial Reporting

        Other than with respect to the ongoing remediation of the material weakness in internal controls over our income tax accounting and reporting for income taxes pursuant to the plan described in Item 9A of our Annual Report on Form 10-K for the fiscal year ended December 28, 2013, there were no changes in our internal control over financial reporting identified in connection with the above evaluation that occurred during the second quarter of fiscal 2014 that have materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

25

Important Considerations

        The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to various inherent limitations, including cost limitations, 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.

PART II. OTHER INFORMATION

ITEM 1.    Legal Proceedings

        None.

ITEM 1A.    Risk Factors

        Our operations are subject to a number of risks. You should carefully read and consider the following risk factors, together with all other information in this report, in evaluating our business. 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. If that happens, the market price of our common stock could decline, and you may lose all or part of your investment.

We depend upon key employees to generate revenue

        Our business consists primarily of the delivery of professional services, and, accordingly, our success depends heavily on the efforts, abilities, business generation capabilities, and project execution capabilities of our employee consultants. In particular, our employee consultants' personal relationships with our clients are a critical element in obtaining and maintaining client engagements. If we lose the services of any employee consultant or group of employee consultants, or if our employee consultants fail to generate business or otherwise fail to perform effectively, that loss or failure could adversely affect our revenues and results of operations. We do not have non-competition agreements with a majority of our employee consultants, and they can terminate their relationships with us at will and without notice. The non-competition and non-solicitation agreements that we have with some of our employee consultants offer us only limited protection and may not be enforceable in every jurisdiction. In the event that an employee leaves, some clients may decide that they prefer to continue working with the employee rather than with us. In the event an employee departs and acts in a way that we believe violates the employee's non-competition or non-solicitation agreement, we will consider any legal remedies we may have against such person on a case-by-case basis. We may decide that preserving cooperation and a professional relationship with the former employee or clients that worked with the employee, or other concerns, outweigh the benefits of any possible legal recovery.

Our business could suffer if we are unable to hire and retain additional qualified consultants as employees

        Our business continually requires us to hire highly qualified, highly educated consultants as employees. Our failure to recruit and retain a significant number of qualified employee consultants could limit our ability to accept or complete engagements and adversely affect our revenues and results of operations. Relatively few potential employees meet our hiring criteria, and we face significant competition for these employees from our direct competitors, academic institutions, government

26

agencies, research firms, investment banking firms, and other enterprises. Many of these competing employers are able to offer potential employees greater compensation and benefits or more attractive lifestyle choices, career paths, or geographic locations than we can. Competition for these employee consultants has increased our labor costs, and a continuation of this trend could adversely affect our margins and results of operations.

Maintaining our professional reputation is crucial to our future success

        Our ability to secure new engagements and hire qualified consultants as employees depends heavily on our overall reputation as well as the individual reputations of our employee consultants and principal non-employee experts. Because we obtain a majority of our new engagements from existing clients, any client that is dissatisfied with our performance on a single matter could seriously impair our ability to secure new engagements. Given the frequently high-profile nature of the matters on which we work, including work before and on behalf of government agencies, any factor that diminishes our reputation or the reputations of any of our employee consultants or non-employee experts could make it substantially more difficult for us to compete successfully for both new engagements and qualified consultants.

We depend on our non-employee experts

        We depend on our relationships with our non-employee experts. We believe that these experts are highly regarded in their fields and that each offers a combination of knowledge, experience, and expertise that would be very difficult to replace. We also believe that we have been able to secure some engagements and attract consultants in part because we can offer the services of these experts. Most of these experts can limit their relationships with us at any time for any reason. These reasons could include affiliations with universities with policies that prohibit accepting specified engagements, termination of exclusive relationships, the pursuit of other interests, and retirement.

        In many cases we seek to include restrictive covenant agreements in our agreements with our non-employee experts, which could include non-competition agreements, non-solicitation agreements and non-hire agreements. The limitation or termination of any of their relationships with us, or competition from any of them after these agreements expire, could harm our reputation, reduce our business opportunities and adversely affect our revenues and results of operations. These restrictive covenant agreements that we may have with some of our non-employee experts offer us only limited protection and may not be enforceable in every jurisdiction. In the event that non-employee experts leave, clients working with these non-employee experts may decide that they prefer to continue working with them rather than with us. In the event a non-employee expert departs and acts in a way that we believe violates the expert's restrictive covenant agreements, we will consider any legal and equitable remedies we may have against such person on a case-by-case basis. We may decide that preserving cooperation and a professional relationship with the former non-employee expert or clients that worked with the non-employee expert, or other concerns, outweigh the benefits of any possible legal action or recovery.

        To meet our long-term growth targets, we need to establish ongoing relationships with additional non-employee experts who have reputations as leading experts in their fields. We may be unable to establish relationships with any additional non-employee experts. In addition, any relationship that we do establish may not help us meet our objectives or generate the revenues or earnings that we anticipate.

Clients can terminate engagements with us at any time

        Many of our engagements depend upon disputes, proceedings, or transactions that involve our clients. Our clients may decide at any time to seek to resolve the dispute or proceeding, abandon the

27

transaction, or file for bankruptcy. Our engagements can therefore terminate suddenly and without advance notice to us. If an engagement is terminated unexpectedly, our employee consultants working on the engagement could be underutilized until we assign them to other projects. In addition, because much of our work is project-based rather than recurring in nature, our consultants' utilization depends on our ability to secure additional engagements on a continual basis. Accordingly, the termination or significant reduction in the scope of a single large engagement could reduce our utilization and have an immediate adverse impact on our revenues and results of operations.

Potential conflicts of interests may preclude us from accepting some engagements

        We provide our services primarily in connection with significant or complex transactions, disputes, or other matters that are usually adversarial or that involve sensitive client information. Our engagement by a client may preclude us from accepting engagements with the client's competitors or adversaries because of conflicts between their business interests or positions on disputed issues or other reasons. Accordingly, the nature of our business limits the number of both potential clients and potential engagements. Moreover, in many industries in which we provide consulting services, such as in the telecommunications industry, there has been a continuing trend toward business consolidations and strategic alliances. These consolidations and alliances reduce the number of potential clients for our services and increase the chances that we will be unable to continue some of our ongoing engagements or accept new engagements as a result of conflicts of interests.

Deterioration of global economic conditions, global market and credit conditions, and regulatory and legislative changes affecting our clients, practice areas, or competitors could have an impact on our business

        Overall global economic conditions and global market and credit conditions in the industries we service can negatively impact the market for our services. These factors are outside of our control and include the availability of credit, the costs and terms of borrowing, merger and acquisition activity, and general economic factors and business conditions.

        Similarly, many of our clients are in highly regulated industries. Regulatory and legislative changes in these industries could also impact the market for our service offerings and could render our current service offerings obsolete, reduce the demand for our services, or impact the competition for consulting and expert services. For example, potential changes in the patent laws could have a significant impact on our intellectual property practice. We are not able to predict the positive or negative effects that future events or changes to the U.S. or international business environment could have on our operations.

We depend on our antitrust and mergers and acquisitions consulting business

        We derive a significant amount of our revenues from engagements related to antitrust and mergers and acquisitions activities. Any substantial reduction in the number or size of our engagements in these areas could adversely affect our revenues and results of operations. Adverse changes in general economic conditions, particularly conditions influencing the merger and acquisition activity of larger companies, could adversely affect engagements in which we assist clients in proceedings before the U.S. Department of Justice, the U.S. Federal Trade Commission, and various foreign antitrust authorities. For example, global economic recessions have resulted in, and may in the future result in, reduced merger and acquisition activity levels. Any of these reductions in activity level would adversely affect our revenues and results of operations.

28

Our failure to execute our business strategy or manage future growth successfully could adversely affect our revenues and results of operations

        Any failure on our part to execute our business strategy or manage future growth successfully could adversely affect our revenues and results of operations. In the future, we could open offices in new geographic areas, including foreign locations, and expand our employee base as a result of internal growth and acquisitions. Opening and managing new offices often requires extensive management supervision and increases our overall selling, general, and administrative expenses. Expansion creates new and increased management, consulting, and training responsibilities for our employee consultants. Expansion also increases the demands on our internal systems, procedures, and controls, and on our managerial, administrative, financial, marketing, and other resources. We depend heavily upon the managerial, operational, and administrative skills of our executive officers to manage our expansion and business strategy. New responsibilities and demands may adversely affect the overall quality of our work.

Competition from other litigation, regulatory, financial, and management consulting firms could hurt our business

        The market for litigation, regulatory, financial, and management consulting services is intensely competitive, highly fragmented, and subject to rapid change. We may be unable to compete successfully with our existing competitors or with any new competitors. In general, there are few barriers to entry into our markets, and we expect to face additional competition from new entrants into the economic and management consulting industries. In the litigation, regulatory, and financial consulting markets, we compete primarily with other economic and financial consulting firms and individual academics. In the management consulting market, we compete primarily with other business and management consulting firms, specialized or industry-specific consulting firms, the consulting practices of large accounting firms, and the internal professional resources of existing and potential clients. Many of our competitors have national or international reputations as well as significantly greater personnel, financial, managerial, technical, and marketing resources than we do, which could enhance their ability to respond more quickly to technological changes, finance acquisitions, and fund internal growth. Some of our competitors also have a significantly broader geographic presence and resources than we do.

We derive our revenues from a limited number of large engagements

        We derive a portion of our revenues from a limited number of large engagements. If we do not obtain a significant number of new large engagements each year, our business, financial condition, and results of operations could suffer. In general, the volume of work we perform for any particular client varies from year to year, and due to the specific engagement nature of our practice, a major client in one year may not hire us in the following year.

Our engagements may result in professional liability and we may be subject to other litigation, claims or assessments

        Our services typically involve difficult analytical assignments and carry risks of professional and other liability. Many of our engagements involve matters that could have a severe impact on a client's business, cause the client to lose significant amounts of money, or prevent the client from pursuing desirable business opportunities. Accordingly, if a client is dissatisfied with our performance, the client could threaten or bring litigation in order to recover damages or to contest its obligation to pay our fees. Litigation alleging that we performed negligently, disclosed client confidential information, or otherwise breached our obligations to the client could expose us to significant liabilities to our clients and other third parties and tarnish our reputation.

29

        Despite our efforts to prevent litigation, from time to time we are party to various lawsuits, claims, or assessments in the ordinary course of business. Disputes may arise, for example, from business acquisitions, employment issues, regulatory actions, and other business transactions. The costs and outcome of any lawsuits or claims could have a material adverse effect on us.

Fluctuations in our quarterly revenues and results of operations could depress the market price of our common stock

        We may experience significant fluctuations in our revenues and results of operations from one quarter to the next. If our revenues or net income in a quarter falls below the expectations of securities analysts or investors, the market price of our common stock could fall significantly. Our results of operations in any quarter can fluctuate for many reasons, including:

•

our ability to implement rate increases;

•

the number, scope, and timing of ongoing client engagements;

•

the extent to which we can reassign our employee consultants efficiently from one engagement to the next;

•

the extent to which our employee consultants or clients take holiday, vacation, and sick time, including traditional seasonality related to summer vacation and holiday schedules;

•

employee hiring;

•

the extent of revenue realization or cost overruns;

•

fluctuations in the results and continuity of the operations of our software subsidiary, NeuCo;

•

fluctuations in our provision for income taxes due to changes in income arising in various tax jurisdictions, valuation allowances, non-deductible expenses, and changes in estimates of our uncertain tax positions;

•

fluctuations in interest rates; and

•

collectability of receivables and unbilled work in process.

        Because we generate a majority of our revenues from consulting services that we provide on an hourly fee basis, our revenues in any period are directly related to the number of our employee consultants, their billing rates, and the number of billable hours they work in that period. We have a limited ability to increase any of these factors in the short term. Accordingly, if we underutilize our consultants during one part of a fiscal period, we may be unable to compensate by augmenting revenues during another part of that period. In addition, we are occasionally unable to utilize fully any additional consultants that we hire, particularly in the quarter in which we hire them. Moreover, a significant majority of our operating expenses, primarily office rent and salaries, are fixed in the short term. As a result, any failure of our revenues to meet our projections in any quarter could have a disproportionate adverse effect on our net income. For these reasons, we believe our historical results of operations are not necessarily indicative of our future performance.

Acquisitions may disrupt our operations or adversely affect our results

        We regularly evaluate opportunities to acquire other businesses. The expenses we incur evaluating and pursuing acquisitions could adversely affect our results of operations. If we acquire a business, we may be unable to manage it profitably or successfully integrate its operations with our own. Moreover, we may be unable to realize the financial, operational, and other benefits we anticipate from these acquisitions or any other acquisition. Many potential acquisition targets do not meet our criteria, and, for those that do, we face significant competition for these acquisitions from our direct competitors,

30

private equity funds, and other enterprises. Competition for future acquisition opportunities in our markets could increase the price we pay for businesses we acquire and could reduce the number of potential acquisition targets. Further, acquisitions may involve a number of special financial and business risks, such as:

•

diversion of our management's time, attention, and resources;

•

decreased utilization during the integration process;

•

loss of key acquired personnel;

•

increased costs to improve or coordinate managerial, operational, financial, and administrative systems including compliance with the Sarbanes- Oxley Act of 2002;

•

dilutive issuances of equity securities, including convertible debt securities;

•

the assumption of legal liabilities;

•

amortization of acquired intangible assets;

•

potential write-offs related to the impairment of goodwill, including if our enterprise value declines below certain levels;

•

difficulties in integrating diverse corporate cultures; and

•

additional conflicts of interests.

Our clients may be unable or unwilling to pay us for our services

        Our clients include some companies that may from time to time encounter financial difficulties, particularly during a downward trend in the economy or may dispute the services we provide. If a client's financial difficulties become severe or a dispute arises, the client may be unwilling or unable to pay our invoices in the ordinary course of business, which could adversely affect collections of both our accounts receivable and unbilled services. On occasion, some of our clients have entered bankruptcy, which has prevented us from collecting amounts owed to us. The bankruptcy of a client with a substantial accounts receivable could have a material adverse effect on our financial condition and results of operations. Historically, a small number of clients who have paid sizable invoices have later declared bankruptcy, and a court determination that we were not properly entitled to any of those payments may require repayment of some or all of them, which could adversely affect our financial condition and results of operations.

        Additionally, from time to time, we may derive a significant amount of revenue from government agencies in the United States. Because we may derive a significant percentage of our revenue from contracts with the Federal government, changes in Federal government budgetary priorities could directly affect our financial performance. This could result in the cancellation of contracts and/or the incurrence of substantial costs without reimbursement under our contracts with the U.S. Government, which could have a negative effect on our business, financial condition, results of operations and cash flows.

Our entry into new lines of business could adversely affect our results of operations

        If we attempt to develop new practice areas or lines of business outside our core litigation, regulatory, financial, and management consulting services, those efforts could harm our results of operations. Our efforts in new practice areas or new lines of business involve inherent risks, including risks associated with inexperience and competition from mature participants in the markets we enter. Our inexperience in these new practice areas or lines of business may result in costly decisions that could harm our business.

31

Our international operations create special risks

        Our international operations carry special financial and business risks, including:

•

greater difficulties in managing and staffing foreign operations;

•

difficulties from fluctuations in world-wide utilization levels;

•

currency fluctuations that adversely affect our financial position and operating results;

•

unexpected changes in trading policies, regulatory requirements, tariffs, and other barriers;

•

different practices in collecting accounts receivable;

•

increased selling, general, and administrative expenses associated with managing a larger and more global organization;

•

longer sales cycles;

•

restrictions on the repatriation of earnings;

•

potentially adverse tax consequences, such as trapped foreign losses or changes in statutory tax rates;

•

the impact of differences in the governmental, legal and regulatory environment in foreign jurisdictions, as well as U.S. laws and regulations related to our foreign operations;

•

less stable political and economic environments; and

•

civil disturbances or other catastrophic events that reduce business activity.

        If our international revenues increase relative to our total revenues, these factors could have a more pronounced effect on our operating results.

Our performance could be affected if employees and non-employee experts default on loans

        We utilize forgivable loans and term loans with some of our employees and non-employee experts, other than our executive officers, as a way to attract and retain them. A portion of the term loans are collateralized. Defaults under these loans could have a material adverse effect on our consolidated statements of operations, financial condition and liquidity.

The market price of our common stock may be volatile

        The market price of our common stock has fluctuated widely and may continue to do so. Many factors could cause the market price of our common stock to rise and fall. Some of these factors are:

•

variations in our quarterly results of operations;

•

the hiring or departure of key personnel or non-employee experts;

•

changes in our professional reputation;

•

the introduction of new services by us or our competitors;

•

acquisitions or strategic alliances involving us or our competitors;

•

changes in accounting principles or methods;

•

changes in estimates of our performance or recommendations by securities analysts;

•

future sales of shares of common stock in the public market; and

•

market conditions in the industry and the economy as a whole.

        In addition, the stock market often experiences significant price and volume fluctuations. These fluctuations are often unrelated to the operating performance of particular companies. These broad

32

market fluctuations may adversely affect the market price of our common stock. When the market price of a company's stock drops significantly, shareholders often institute securities class action litigation against that company. Any litigation against us could cause us to incur substantial costs, divert the time and attention of our management and other resources, or otherwise harm our business.

Our stock repurchase program could affect the market price of our common stock and increase its volatility.

        Our Board of Directors has from time to time authorized repurchase programs of our outstanding common stock. Under these stock repurchase programs, we are authorized to repurchase, from time-to-time, shares of our outstanding common stock on the open market or in privately negotiated transactions. The timing and amount of stock repurchases will be determined based upon our evaluation of market conditions and other factors. The stock repurchase program may be suspended, modified or discontinued at any time, and we have no obligation to repurchase any amount of our common stock under the program. Repurchases pursuant to our stock repurchase program could affect the market price of our common stock and increase its volatility. Any termination of our stock repurchase programs could cause a decrease in the market price of our common stock price, and the existence of a stock repurchase program could cause our stock price to be higher than it would be in the absence of such a program and could potentially reduce the market liquidity of our common stock. There can be no assurance that any stock repurchases under these programs will enhance stockholder value because the market price of our common stock may decline below the levels at which those repurchases were made. Although our stock repurchase program is intended to enhance long-term stockholder value, short-term fluctuations in the market price of our common stock could reduce the program's effectiveness.

Our debt obligations may adversely impact our financial performance

        We have a revolving line of credit with our bank for $125.0 million. The amounts available under this line of credit are constrained by various financial covenants and reduced by certain letters of credit outstanding. Our loan agreement with the bank will mature on April 24, 2018. The degree to which we are leveraged could adversely affect our ability to obtain further financing for working capital, acquisitions or other purposes and could make us more vulnerable to industry downturns and competitive pressures. Our ability to secure short-term and long-term debt or equity financing in the future will depend on several factors, including our future profitability, the levels of our debt and equity, restrictions under our existing revolving line of credit, and the overall credit and equity market environments.

We may need to take material write-offs for the impairment of goodwill and other intangible assets, including if our market capitalization declines

        As further described in our Notes to Consolidated Financial Statements, goodwill and intangible assets with indefinite lives are monitored annually for impairment, or more frequently, if events or circumstances exist that would more likely than not reduce our fair value below our carrying amount. In performing the first step of the goodwill impairment testing and measurement process, we compare our entity-wide estimated fair value to net book value to identify potential impairment. We estimate the entity-wide fair value utilizing our market capitalization, plus an appropriate control premium. Market capitalization is determined by multiplying the shares outstanding on the test date by the market price of our common stock on that date. We have utilized a control premium that considers appropriate industry, market and other pertinent factors, including indications of such premiums from data on recent acquisition transactions. If our fair value is less than our net book value, the second step is performed to determine if goodwill is impaired. If we determine through the impairment evaluation process that goodwill has been impaired, an impairment charge would be recorded in our consolidated income statement.

33

        A goodwill impairment charge in any period would have the effect of decreasing our earnings in such period. If we are required to take a substantial impairment charge, our operating results would be materially adversely affected in such period, though such a charge would have no impact on cash flows or working capital.

Fluctuations in the types of service contracts we enter into may adversely impact revenue and results of operations

        We derive a portion of our revenues from fixed-price contracts. These contracts are more common in our management consulting area, and would likely grow in number with expansion of that area. Fluctuations in the mix between time-and- material contracts, fixed-price contracts and arrangements with fees tied to performance-based criteria may result in fluctuations of revenue and results of operations. In addition, if we fail to estimate accurately the resources required for a fixed-price project or fail to satisfy our contractual obligations in a manner consistent with the project budget, we might generate a smaller profit or incur a loss on the project. On occasion, we have had to commit unanticipated additional resources to complete projects, and we may have to take similar action in the future, which could adversely affect our revenues and results of operations.

We could incur substantial costs protecting our proprietary rights from infringement or defending against a claim of infringement

        As a professional services organization, we rely on non-competition and non-solicitation agreements with many of our employees and non-employee experts to protect our proprietary rights. These agreements, however, may offer us only limited protection and may not be enforceable in every jurisdiction. In addition, we may incur substantial costs trying to enforce these agreements.

        Our services may involve the development of custom business processes or solutions for specific clients. In some cases, the clients retain ownership or impose restrictions on our ability to use the business processes or solutions developed from these projects. Issues relating to the ownership of business processes or solutions can be complicated, and disputes could arise that affect our ability to resell or reuse business processes or solutions we develop for clients.

        In recent years, there has been significant litigation in the U.S. involving patents and other intellectual property rights. We could incur substantial costs in prosecuting or defending any intellectual property litigation, which could adversely affect our operating results and financial condition.

        Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to obtain and use information that we regard as proprietary. Litigation may be necessary in the future to enforce our proprietary rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement or invalidity. Any such resulting litigation could result in substantial costs and diversion of resources and could adversely affect our business, operating results and financial condition. Any failure by us to protect our proprietary rights, or any court determination that we have either infringed or lost ownership of proprietary rights could adversely affect our business, operating results and financial condition.

Insurance and claims expenses could significantly reduce our profitability

        We are exposed to claims related to group health insurance. We self-insure a portion of the risk associated with these claims. If the number or severity of claims increases, or we are required to accrue or pay additional amounts because the claims prove to be more severe than our original assessment, our operating results would be adversely affected. Our future insurance and claims expense might exceed historical levels, which could reduce our earnings. We expect to periodically assess our self-insurance strategy. We are required to periodically evaluate and adjust our claims reserves to reflect our experience. However, ultimate results may differ from our estimates, which could result in losses over our reserved amounts. We maintain individual and aggregate medical plan stop loss

34

insurance with licensed insurance carriers to limit our ultimate risk exposure for any one case and for our total liability.

        Many businesses are experiencing the impact of increased medical costs as well as greater variability in ongoing costs. As a result, our insurance and claims expense could increase, or we could raise our self-insured retention when our policies are renewed. If these expenses increase or we experience a claim for which coverage is not provided, results of our operations and financial condition could be materially and adversely affected.

Information or technology systems failures, or a compromise of our or our client's confidential or proprietary information, could have a material adverse effect on our reputation, business and results of operations

        We rely upon information and technology infrastructure and systems to operate, manage and run our business and to provide services to our clients. This includes infrastructure and systems for receiving, storing, hosting, analyzing, transmitting and securing our and our clients' sensitive, confidential or proprietary information, including, but not limited to, health and other personally-identifiable information and commercial, financial and consumer data. Our ability to secure and maintain the confidentiality of this information is critical to our reputation and the success of our businesses. We may be affected by or subject to events that are out of our control, including, but not limited to, viruses, malicious software, worms, failures in our or our third party hosting sites' information and technology systems, disruptions in the Internet or electricity grids, natural disasters, terrorism and malicious attacks, and unauthorized intrusions by unknown third parties. Any of these events could disrupt our or our client's business operations or cause us or our clients to incur unanticipated losses and reputational damage, which could have a material adverse effect on our business and results of operations.

        In addition, our or our clients' sensitive, confidential or proprietary information could be compromised, whether intentionally or unintentionally, by our employees, outside consultants or vendors. A breach or compromise of the security of our information technology systems or infrastructure, or our processes for securing sensitive, confidential or proprietary information, could result in the loss or misuse of this information. Any such loss or misuse could result in our suffering claims, fines, damages, losses or reputational damage, any of which could have a material adverse effect on our business and results of operations.

Our charter and by-laws, and Massachusetts law may deter takeovers

        Our amended and restated articles of organization and amended and restated by-laws and Massachusetts law contain provisions that could have anti-takeover effects and that could discourage, delay, or prevent a change in control or an acquisition that our shareholders may find attractive. These provisions may also discourage proxy contests and make it more difficult for our shareholders to take some corporate actions, including the election of directors. These provisions could limit the price that investors might be willing to pay for shares of our common stock.

        (b)   Not applicable.

        (c)   The following table provides information about our repurchases of shares of our common stock during the fiscal quarter ended June 28, 2014. 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 second quarter of fiscal 2014.

On August 10, 2012 and February 13, 2014, our Board of Directors authorized the repurchase of up to $5.0 million and $15 million, respectively, of our common stock. All the shares indicated were repurchased under these programs and then retired. Approximately $10.9 million was available for future repurchases under these programs as of June 28, 2014. We expect to continue to repurchase shares under these programs.

Unaudited Interim Condensed Consolidated Financial Statements and Estimates

2. Unaudited Interim Condensed Consolidated Financial Statements and Estimates

        The following financial statements included in this report are unaudited: the condensed consolidated income statements for the fiscal quarters and year to date periods ended June 28, 2014 and June 29, 2013, the condensed consolidated statements of comprehensive income for the fiscal quarters and year to date periods ended June 28, 2014 and June 29, 2013, the condensed consolidated balance sheet as of June 28, 2014, the condensed consolidated statements of cash flows for the fiscal year to date periods ended June 28, 2014 and June 29, 2013, and the condensed consolidated statement of shareholders' equity for the fiscal year to date period ended June 28, 2014. In the opinion of management, these statements include all adjustments necessary for a fair presentation of CRA's consolidated financial position, results of operations, and cash flows. The condensed consolidated balance sheet as of December 28, 2013 included in this report was derived from audited consolidated financial statements included in CRA's Annual Report on Form 10-K that was filed on March 13, 2014.

        The preparation of financial statements in conformity with generally accepted accounting principles in the U.S. ("U.S. GAAP") requires management to make significant estimates and judgments that affect the reported amounts of assets and liabilities, and 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 consolidated financial statements include, but are not limited to, accounts receivable allowances, 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 statement of cash flows for the fiscal year to date period ended June 29, 2013 has been adjusted to properly present payments of debt issuance costs, which were previously presented in cash used in operating activities and have been reclassified to cash used in financing activities. This revision is not material to CRA's consolidated financial statements taken as a whole.

10. Revenue Recognition

        CRA derives substantially all of its revenues from the performance of professional services. CRA's revenues include projects secured by our non-employee experts as well as projects secured by our employees. 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.

        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):

	Quarter Ended				Fiscal Year to Date Period Ended
	June 28, 2014		June 29, 2013		June 28, 2014		June 29, 2013
Reimbursable expenses	$	8,658	$	9,750	$	17,686	$	17,408

        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

11. Net Income per Share

        Basic net income per share represents net income divided by the weighted average shares of common stock outstanding during the period. Diluted net income per share represents net income divided by the weighted average shares of common stock and common stock equivalents, if applicable, outstanding during the period. Common stock equivalents arise from stock options and unvested shares of restricted stock, using the treasury stock method. Under the treasury stock method, the amount CRA would receive on the exercise of stock options and the vesting of shares of restricted stock, the amount of compensation cost for future service that CRA has not yet recognized, and the amount of tax benefits that would be recorded in common stock when these stock options and shares of restricted stock become deductible, are assumed to be used to repurchase shares at the average share price over the applicable fiscal period, and these repurchased shares are netted against the shares underlying these stock options and these unvested shares of restricted stock. CRA's unvested shares of restricted stock that contain rights to receive non-forfeitable dividends are considered participating securities, but net earnings available to these participating securities were not significant for the second quarter and the first half of fiscal 2014. A reconciliation of basic to diluted weighted average shares of common stock outstanding is as follows (in thousands):

	Quarter Ended				Fiscal Year to Date Period Ended
	June 28, 2014		June 29, 2013		June 28, 2014		June 29, 2013
Basic weighted average shares outstanding		9,919		10,100		9,974		10,085
Common stock equivalents:
Stock options and restricted shares		107		88		93		89
Diluted weighted average shares outstanding		10,026		10,188		10,067		10,174

        For the second quarter and fiscal year-to-date period ended June 28, 2014, certain share-based awards, which amounted to 888,746 and 1,088,180 shares, respectively, were excluded from the calculation of common stock equivalents for purposes of computing diluted weighted average shares outstanding because they were anti-dilutive. For the second quarter and fiscal year to date period ended June 29, 2013, 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 1,065,240 and 1,103,932 shares, respectively. These share-based awards were anti-dilutive because their exercise price exceeded the average market price over the respective period.

        On August 10, 2012 and February 13, 2014, the Board of Directors authorized the repurchase of up to $5.0 million and $15.0 million, respectively, of CRA's common stock. During the second quarter of fiscal 2014, CRA repurchased and retired 157,000 shares under these share repurchase programs at an average price per share of $21.70. During the first half of fiscal 2014, CRA repurchased and retired 252,600 shares under these share repurchase programs at an average price per share of $21.91. During the first half of fiscal 2013, CRA did not repurchase and retire any shares of its common stock under these programs. There was approximately $10.9 million available for future repurchases under these programs as of June 28, 2014. CRA may repurchase shares under these programs in open market purchases or in privately negotiated transactions in accordance with applicable insider trading and other securities laws and regulations.

5. Cash and Cash Equivalents

        Cash equivalents consist principally of money market funds with maturities of three months or less when purchased. As of June 28, 2014, 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 the cash on deposit is fully liquid. CRA continually monitors the credit ratings of this institution.

        The carrying amounts of these instruments classified as cash equivalents are stated at amortized cost, which approximates fair value because of their short-term maturity.

4. Recent Accounting Standards

Accounting for Share-Based Payments

        In June 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force) ("ASU 2014-12"). ASU 2014-12 clarifies that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting. Therefore, an entity would not record compensation expense (measured as of the grant date without taking into account the effect of the performance target) related to an award for which transfer to the employee is contingent on the entity's satisfaction of a performance target until it becomes probable that the performance target will be met. No new disclosures are required under ASU 2014-12. ASU 2014-12 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. CRA believes that the adoption of ASU 2014-12 will not have a material impact on its financial position, results of operations, cash flows, or disclosures.

Revenue from Contracts with Customers

        In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). 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. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. CRA has not yet determined the effects, if any, that the adoption of ASU 2014-09 may have on its financial position, results of operations, cash flows, or disclosures.

Presentation of Unrecognized Tax Benefits

        In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11") to clarify the presentation of current and deferred income taxes on the balance sheet. Under ASU 2013-11, companies generally must present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, for a net operating loss carryforward, similar tax loss, or tax credit carryforward using the "net presentation" approach as a reduction of a deferred tax asset, with some allowed exceptions. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. CRA's adoption of ASU 2013-11 in the first quarter of fiscal 2014 had no impact on its financial position, results of operations, cash flows, or disclosures.

Cumulative Translation Adjustment

        In March 2013, the FASB issued ASU No. 2013-05, Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity ("ASU 2013-05"). ASU 2013-05 addresses the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. ASU 2013-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and should be applied prospectively. CRA's adoption of ASU 2013-05 in the first quarter of fiscal 2014 had no impact on its financial position, results of operations, cash flows, or disclosures.

12. Income Taxes

        CRA's effective income tax rates were 50.0% and 59.9% for the second quarters of fiscal 2014 and fiscal 2013, respectively. The effective tax rate in the second quarter of fiscal 2014 was higher than CRA's combined Federal and state statutory tax rate primarily due to a non-cash tax expense recorded in the second quarter of fiscal 2014 to correct an error in its previously issued consolidated financial statements. During the second quarter of fiscal 2014, CRA identified the prior period error, which was related to the valuation of deferred tax assets in CRA's previously issued consolidated financial statements, concluded that this error was not material to its prior reporting periods, and recorded a non-cash tax expense of approximately $0.8 million to correct this error.

        CRA's effective income tax rates were 44.7% and 37.9% for the fiscal year to date periods ended June 28, 2014 and June 29, 2013, respectively. The effective tax rate for the fiscal year to date period ended June 28, 2014 was higher than CRA's combined Federal and state statutory tax rate primarily due to the approximately $0.8 million non-cash tax expense recorded in the second quarter of fiscal 2014 to correct the error in CRA's previously issued consolidated financial statements, described earlier in this note 12, partially offset by certain favorable tax adjustments that were treated as discrete items in the first half of fiscal 2014.

        The effective tax rate for the second quarter of fiscal 2013 was higher than CRA's combined Federal and state statutory tax rate primarily due to losses in foreign jurisdictions that provided no tax benefit. In addition, during the second quarter of fiscal 2013, CRA incurred a charge for a one-time tax adjustment of approximately $0.3 million. The effective tax rate for the fiscal year to date period ended June 29, 2013 was lower than CRA's combined Federal and state statutory tax rate primarily due to the favorable settlement of a tax matter in the first quarter of fiscal 2013, partially offset by a one-time tax adjustment recorded in the second quarter of fiscal 2013 and the effect of losses in foreign jurisdictions that provided no tax benefit in the first half of fiscal 2013.

        CRA has not provided for deferred income taxes or foreign withholding taxes on undistributed earnings from its foreign subsidiaries as of June 28, 2014 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. credit lines 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.

Total	$	48,199	$	54,621

        In order to attract and retain highly skilled professionals, CRA may issue forgivable loans or term loans to employees and non-employee experts which are classified in "prepaid expenses and other current assets" and "other assets" within the accompanying balance sheets as of June 28, 2014 and December 28, 2013. A portion of the term loans are 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 CRA over the term of the loans, so long as the employee or non-employee expert continues employment or affiliation with CRA 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. During the second quarter of fiscal 2014, CRA issued approximately $0.7 million in forgivable loans to employees and non-employee experts for future service. As of June 28, 2014, CRA had obligations to issue approximately $4.1 million in forgivable loans to employees, future employees, and non-employee experts for future service, which are included in the $45.3 million of such loans reported as of June 28, 2014 in the table above. CRA expects that the $4.1 million in loans will be issued, and the corresponding payments will be made, before the end of the third quarter of fiscal 2014.

7. Goodwill

        In accordance with Accounting Standards Codification ("ASC") Topic 350, Intangibles—Goodwill and Other, goodwill is not subject to amortization, but is monitored at least annually for impairment, or more frequently, as necessary, if events or circumstances exist that would more likely than not reduce the fair value of the reporting unit below its carrying amount. For CRA's goodwill impairment analysis, CRA operates under one reporting unit. Under ASC Topic 350, in performing the first step of the goodwill impairment testing and measurement process, CRA compares its entity-wide estimated fair value to its net book value to identify potential impairment. Management estimates the entity-wide fair value utilizing CRA's market capitalization, plus an appropriate control premium. Market capitalization is determined by multiplying the shares outstanding on the test date by the market price of CRA's common stock on that date. CRA has utilized a control premium that considers appropriate industry, market and other pertinent factors, including indications of such premiums from data on recent acquisition transactions. If the fair value of CRA is less than its net book value, the second step is performed to determine if goodwill is impaired. If CRA determines through the impairment evaluation process that goodwill has been impaired, an impairment charge would be recorded in its consolidated income statements.

        There were no impairment losses related to goodwill during each of the fiscal year to date periods ended June 28, 2014 and June 29, 2013, respectively, as there were no events or circumstances that would more likely than not reduce CRA's fair value below its carrying amount.

        CRA continues to monitor its market capitalization. If CRA's market capitalization, plus an estimated control premium, is below its net book value for a period considered to be other-than-temporary, it is possible that CRA may be required to record an impairment of goodwill either as a result of the annual assessment that CRA conducts in the fourth quarter of each fiscal year, or in a future quarter if events or circumstances exist that would more likely than not reduce CRA's fair value below its carrying amount. A non-cash goodwill impairment charge would have the effect of decreasing CRA's earnings in such period.

        The changes in the carrying amount of goodwill during the fiscal year to date period ended June 28, 2014, are as follows (in thousands):

	Goodwill, gross		Accumulated impairment losses			Goodwill, net

9. Credit Agreement

        As of June 28, 2014, 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 loans for working capital and 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 was no amount outstanding under this revolving line of credit as of June 28, 2014.

        As of June 28, 2014, the amount available under this revolving line of credit was reduced by certain letters of credit outstanding, which amounted to $1.4 million. Borrowings under the revolving credit facility bear interest at a rate per annum 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 CRA's 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 CRA's total leverage ratio. CRA is 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 its total leverage ratio. Borrowings under the credit facility are secured by 100% of the stock of certain of CRA's U.S. subsidiaries and 65% of the stock of certain of its foreign subsidiaries, which represent approximately $7.0 million in net assets as of June 28, 2014.

        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. Any indebtedness outstanding under the credit facility may become immediately due and payable upon the occurrence of stated events of default, including CRA's failure to pay principal, interest or fees or a violation of any financial covenant. The financial covenants require CRA to maintain a consolidated interest expense to adjusted consolidated EBITDA ratio of more than 2.5 to 1.0 and to comply with a consolidated debt to adjusted consolidated EBITDA ratio of not more than 3.0 to 1.0. The non-financial covenant restrictions of the senior credit agreement include, but are not limited to, CRA's ability to incur additional indebtedness, engage in acquisitions or dispositions, and enter into business combinations. As of June 28, 2014, CRA was in compliance with the covenants of its credit agreement.

        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. ("NeuCo"). All significant intercompany accounts have been eliminated.

        CRA's ownership interest in NeuCo constitutes control under U.S. GAAP for all periods presented. Therefore, NeuCo's financial results have been consolidated with CRA and the portion of NeuCo's results allocable to its other owners is shown as "noncontrolling interest."

        NeuCo'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 NeuCo. CRA does not believe that the reporting lag will have a significant impact on CRA's consolidated income statements or financial condition.
