Notes to Condensed Consolidated Financial Statements

(Unaudited)

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

The accompanying unaudited condensed consolidated financial statements reflect the results of operations, financial position, cash flows, and shareholders' equity as of and for the fiscal quarters and year-to-date periods ended June 30, 2018 and July 1, 2017, respectively. These financial statements have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (SEC) for Quarterly Reports on Form 10-Q. Accordingly, these financial statements do not include all the information and note disclosures required by accounting principles generally accepted in the United States of America (GAAP) for annual financial statements. In the opinion of management, these financial statements reflect all adjustments of a normal, recurring nature necessary for the fair statement of CRA's results of operations, financial position, cash flows, and shareholders' equity for the interim periods presented in conformity with GAAP. Results of operations for the interim periods presented herein are not necessarily indicative of results of operations for a full year. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the fiscal year ended December 30, 2017 included in CRA's Annual Report on Form 10-K filed with the SEC on March 12, 2018.

The preparation of financial statements in conformity with GAAP requires management to make significant estimates and judgments that affect the reported amounts of assets and liabilities, as well as the related disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of consolidated revenues and expenses during the reporting period. Estimates in these condensed consolidated financial statements include, but are not limited to, allowances for accounts receivable and unbilled services, revenue recognition on fixed price contracts, depreciation of property and equipment, share-based compensation, valuation of acquired intangible assets, impairment of long lived assets, goodwill, accrued and deferred income taxes, valuation allowances on deferred tax assets, valuation of contingent consideration, accrued compensation, and other accrued expenses. These items are monitored and analyzed by CRA for changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are recorded in the period in which they become known. CRA bases its estimates on historical experience and various other assumptions that CRA believes to be reasonable under the circumstances. Actual results may differ from those estimates if CRA's assumptions based on past experience or other assumptions do not turn out to be substantially accurate.

The condensed consolidated financial statements include the accounts of CRA and its wholly owned subsidiaries. In addition, as more fully explained below, the condensed consolidated financial statements include CRA's interest in GNU123 Liquidating Corporation ("GNU", formerly known as

NeuCo, Inc.). All significant intercompany transactions and accounts have been eliminated in consolidation.

CRA's ownership interest in GNU was 55.89% for all periods presented. GNU's financial results have been consolidated with CRA, and the portion of GNU's results allocable to its other owners is shown as "noncontrolling interest."

On April 13, 2016, a buyer acquired substantially all the business assets and assumed substantially all the liabilities of GNU for a purchase price of $1.35 million. Of this amount, $1.1 million was received at closing, and the remaining $0.25 million was paid in full on May 3, 2017. GNU recognized a gain on sale of its business assets of $0.25 million during the second quarter of fiscal 2017, of which $0.14 million is attributed to CRA. GNU was dissolved on December 15, 2017. In December 2017, CRA received a partial distribution of $0.6 million in accordance with the asset purchase agreement. The final distribution is expected to be received during fiscal 2018, refer to Note 19.

CRA adopted Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASC 606), which established Accounting Standards Codification ("ASC") Topic 606, on December 31, 2017, using the modified retrospective method for all contracts not completed as of the date of adoption. The reported results for fiscal 2018 reflect the application of ASC 606 guidance while the reported results for fiscal 2017 were prepared under the guidance of ASC 605, Revenue Recognition (ASC 605). The cumulative effect of applying ASC 606 to all contracts with customers that were not completed as of December 30, 2017 amounted to $0.4 million. The cumulative effect adjustment resulted in an increase to CRA's fiscal 2018 opening balance of retained earnings of $0.4 million, net of tax. Prior periods were not retrospectively adjusted.

CRA adopted ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18") on January 1, 2018. ASU 2016-18 amends ASC 230 to add or clarify guidance on the classification and presentation of restricted cash in the statement of cash flows. The new standard requires cash and cash equivalents balances on the statement of cash flows to include restricted cash and cash equivalent balances. ASU 2016-18 requires a company to provide appropriate disclosures about its accounting policies pertaining to restricted cash in accordance with GAAP. Additionally, changes in restricted cash and restricted cash equivalents that result from transfers between cash, cash equivalents, and restricted cash and restricted cash equivalents are not to be presented as cash flow activities in the statement of cash flows. The adoption of ASU 2016-18 did not have a material impact on CRA's financial position, results of operations, cash flows, or disclosures.

CRA adopted ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business ("ASU 2017-01") on January 1, 2018. ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist companies and other reporting organizations with evaluating

whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the amendments, a business is an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to investors or other owners, members, or participants. The adoption of ASU 2017-01 did not have a material impact on CRA's financial position, results of operations, cash flows, or disclosures.

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

CRA adopted ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04") on January 1, 2018. ASU 2017-04 simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. Under the amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the charge recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment charge, if applicable. The amendments also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. The adoption of ASU 2017-04 did not have a material impact on CRA's financial position, results of operations, cash flows, or disclosures.

Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting

CRA adopted ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09") on January 1, 2018. ASU 2017-09 updates guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. Under the amendments, an entity should account for the effects of a modification unless all the following conditions are met. First, the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification. Second, the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified. Third, the classification of the modified award as an equity instrument or a liability is the same as the classification of the original award immediately before the original award is modified. The adoption of ASU 2017-09 did not have a material impact on CRA's financial position, results of operations, cash flows, or disclosures.

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118, "Income Tax Accounting Implications of the Tax Cuts and Jobs Act" ("SAB 118"), to address the application of GAAP in situations when a company does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act (the "Tax Act"). SAB 118 summarizes a three-step process to be applied at each reporting period to account for and disclose: (1) the effects of the change in tax law for which accounting is complete; (2) provisional amounts (or adjustments to provisional amounts) for the effects of the change in tax law where accounting is not complete, but a reasonable estimate has been determined; and (3) current or deferred tax amounts reflected in accordance with law prior to the enactment of the change in tax law because the accounting of the effects of the change in tax law are not complete and a reasonable estimate has not been determined, together with qualitative disclosure of the effects of the changes in tax law for which the accounting is not compete, the reason why the accounting is not complete, and the additional information that is needed to be obtained, prepared or analyzed in order to complete the accounting. Because the Tax Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretations are expected over the next 12 months, CRA considers the accounting of deferred tax remeasurements and other items to be incomplete due to the forthcoming guidance and CRA's ongoing analysis of final year-end data and tax positions. Adjustments to these preliminary amounts identified during the measurement period, as defined, will be included as an adjustment to tax expense from continuing operations in the period in which the amounts are determined. CRA believes that it has made a good faith effort to complete the accounting under ASC 740 with respect to the Tax Act. SAB 118 provides that the measurement period is complete when a company's accounting is complete and in no circumstances, should the measurement period extend beyond one year from the enactment date of the applicable change in tax law.

In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 establishes a comprehensive new lease accounting model. The new standard clarifies the definition of a lease, requires a dual approach to lease classification similar to current lease classifications, and causes lessees to recognize leases on the balance sheet as a lease liability with a corresponding right-of-use asset for leases with a lease term of more than 12 months. The new standard is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The new standard requires a modified retrospective transition for capital or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements, but it does not require transition accounting for leases that expire prior to the date of initial application. While the Company is currently evaluating the impact of adopting ASU 2016-02, based on the lease portfolio as of June 30, 2018, the Company anticipates recording a right of use asset and a lease liability that will materially increase its assets and liabilities on the consolidated balance sheet. The Company continues to evaluate the impact on its consolidated income statement.

In July 2018, the FASB issued Accounting Standards Update ("ASU") No. 2018-10, Codification Improvements to Topic 842, Leases ("ASU 2018-10"). ASU 2018-10 clarifies or corrects unintended application of guidance related to ASU 2016-02. The amendment affects narrow aspects of ASU 2016-02 related to (1) residual value guarantees, (2) rate implicit in the lease, (3) lessee reassessment of lease clarification, (4) lessor reassessment of lease term and purchase option, (5) variable lease payments that depend on an index or a rate, (6) investment tax credits, (7) lease term and purchase option, (8) transition guidance for amounts previously recognized in business combinations, (9) certain transition adjustments, (10) transition guidance for leases previously classified as capital leases under Topic 840, (11) transition guidance for modifications to leases previously classified as direct financing or sales-type leases under Topic 840, (12) transition guidance for sale and leaseback transactions, (13) impairment of net investment in the lease, (14) unguaranteed residual assets, (15) effect of initial direct costs on rate implicit in the lease, and (16) failed sale and leaseback transactions. The amendments in this update affect the amendments in ASU 2016-02, which are not yet effective, but for which early adoption upon issuance is permitted. CRA has not yet determined the effects, if any, that the adoption of ASU 2018-10 may have on its financial position, results of operations, cash flows, or disclosures.

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

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting (Topic 718) ("ASU 2018-07"). ASU 2018-07 expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments in this update specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor's own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used effectively to provide financing to the issuer or awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The new guidance is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The new guidance requires a remeasurement of nonemployee awards at fair value as of the adoption date and disclosure of the nature of and reason for the change in accounting principle and, if applicable, quantitative information about the cumulative effect of the change on retained earnings or other components of shareholders' equity. CRA has not yet determined the effects, if any, that the adoption of ASU 2018-07 may have on its financial position, results of operations, cash flows, or disclosures.

On January 31, 2017, CRA acquired C1 Consulting LLC, an independent consulting firm, and its wholly-owned subsidiary C1 Associates (collectively, "C1") for initial consideration comprised of cash and CRA restricted common stock. The asset purchase agreement provided for additional purchase consideration to be paid for up to four years following the transaction in the form of an earnout, if specific performance targets are met. These earnout payments are payable in cash and CRA restricted common stock. The fair value of this obligation was measured as of the acquisition date and accounted

for as a component of the purchase consideration. Any adjustments to the initial valuation of the obligation in future accounting periods will be reported as an adjustment to net income. The acquisition accounting resulted in the recognition of goodwill of $13.0 million, amortizable intangible assets of $8.5 million and a contingent consideration liability of $2.4 million.

Cash equivalents consist principally of money market funds with maturities of three months or less when purchased. As of June 30, 2018, a substantial portion of CRA's cash accounts was concentrated at a single financial institution, which potentially exposes CRA to credit risks. The financial institution has a short-term credit rating of A-2 by Standard & Poor's ratings services. CRA has not experienced any losses related to such accounts. CRA does not believe that there is significant risk of non-performance by the financial institution, and its cash on deposit is fully liquid. CRA continually monitors the credit ratings of the institution.

Results of operations for CRA's non-U.S. subsidiaries are translated from the designated functional currency to the reporting currency of the U.S. dollar. Revenues and expenses are translated at average exchange rates for each month, while assets and liabilities are translated at balance sheet date exchange rates. The resulting net translation adjustments are recorded as a component of shareholders' equity in "Accumulated other comprehensive income (loss)."

Transaction gains and losses arising from currency exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are included in on the condensed consolidated income statements. Such transaction gains and losses may be realized or unrealized depending upon whether the transaction settled during the period or remains outstanding at the balance sheet date.

ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1 measurement), then priority to quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market (Level 2 measurement), then the lowest priority to unobservable inputs (Level 3 measurement).

The following table shows CRA's financial instruments as of June 30, 2018 and December 30, 2017 that are measured and recorded in the financial statements at fair value on a recurring basis (in thousands):

The fair values of CRA's money market funds are based on quotes received from third-party banks. The carrying value of CRA's revolving line of credit approximates the fair value based upon the short-term nature of the arrangement and the variable interest rate.

The contingent consideration liability in the tables above is for estimated future contingent consideration payments related to a prior acquisition. These deferred payments are recorded at fair value at the time of acquisition and are included in other current and/or non-current liabilities on our consolidated balance sheet. The fair value of the contingent consideration is determined using the Monte Carlo simulation (in a risk-neutral framework). The fair value of this liability is based on significant inputs not observed in the market, such as internally generated projections of future profitability, as well as related volatility and discount rates, and thus represent a Level 3 measurement. The fair value of this contingent acquisition liability is reassessed on a quarterly basis by CRA using additional information as it becomes available, and any change in the fair value estimates are recorded in cost of services on the condensed consolidated income statement of that period.

The following table summarizes the changes in the contingent consideration liabilities over the fiscal year-to-date period ended June 30, 2018 and the fiscal year ended December 30, 2017 (in thousands):

Forgivable loan activity for the fiscal year-to-date period ended June 30, 2018 and the fiscal year ended December 30, 2017 is as follows (in thousands):

The changes in the carrying amount of goodwill during the fiscal year-to-date period ended June 30, 2018, are as follows (in thousands):

Intangible assets that are separable from goodwill and have determinable useful lives are valued separately and amortized over their expected useful lives. There were no impairment losses related to intangible assets during the second quarter of fiscal 2018. There were impairment losses of $0.5 million related to intangible assets during the second quarter of fiscal 2017.

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

As of June 30, 2018 and December 30, 2017, approximately $36.2 million and $63.8 million, respectively, of accrued bonuses were included above in "Compensation and related expenses". Additionally, as of June 30, 2018, "Other" accrued expenses include $4.7 million of commissions due to senior consultants, $1.0 million of direct project accruals, $5.7 million of operating expense accruals and $4.1 million of accrued leasehold improvements. As of December 30, 2017, "Other" accrued expenses include $6.1 million of commissions due to senior consultants, $1.3 million of direct project accruals, $4.4 million of operating expense accruals and $2.5 million of accrued leasehold improvements.

CRA is party to a credit agreement that provides CRA with a $125.0 million revolving credit facility and a $15.0 million sublimit for the issuance of letters of credit. CRA may use the proceeds of the revolving credit facility to provide working capital and for other general corporate purposes. CRA may repay any borrowings under the revolving credit facility at any time, but no later than October 24, 2022. There were $20.8 million in borrowings outstanding under this revolving credit facility as of June 30, 2018, which consisted of $17.5 million in the U.S. and £2.5 million in the U.K., refer to Note 19. These borrowings are expected to be repaid over the next 12 months in accordance with the terms of the agreement. There were no outstanding borrowings on this facility as of December 30, 2017.

As of June 30, 2018, the amount available under this revolving credit facility was reduced by certain letters of credit outstanding, which amounted to $3.9 million. Under the credit agreement, CRA must comply with various financial and non-financial covenants. Compliance with these financial covenants is tested on a fiscal quarterly basis. As of June 30, 2018 and December 30, 2017, CRA was in compliance with the covenants of its credit agreement.

CRA offers consulting services in two broad lines: litigation, regulatory, and financial consulting and management consulting. Together, these two service lines comprised all of CRA's consolidated revenues during the fiscal quarter ended June 30, 2018. CRA recognizes all project revenue on a gross basis based on consideration of the criteria set forth in ASC Topic 606-10-55, Principal versus Agent Considerations. Revenue recognized during the fiscal quarter and fiscal year-to-date periods ended June 30, 2018 under ASC 606 are not materially different from the revenues that would have been recognized under ASC 605.

CRA evaluates its revenue contracts with customers based on the five-step model under ASC 606: (1) Identify the contract with the customer; (2) Identify the performance obligations in the contract; (3) Determine the transaction price; (4) Allocate the transaction price to separate performance obligations; and (5) Recognize revenue when (or as) each performance obligation is satisfied. CRA evaluates its contracts for legal enforceability at contract inception and subsequently throughout CRA's relationship with its customers. If legal enforceability with regards to the rights and obligations exist for both CRA and the customer, then CRA has an enforceable contract and revenue recognition is permitted subject to the satisfaction of the other criteria. If, at the outset of an arrangement, CRA determines that a contract with enforceable rights and obligations does not exist, revenues are deferred until all criteria for an enforceable contract are met.

Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the promised consulting services are transferred to customers. Revenue is measured as the amount of consideration CRA expects to receive in exchange for transferring consulting services to a customer ("transaction price"). To the extent the transaction price includes variable consideration, CRA estimates the amount of variable consideration that should be included in the transaction price utilizing the most likely amount to which it expects to be entitled. Variable consideration is included in the transaction price if, in CRA's judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are

based largely on an assessment of CRA's anticipated performance and all information (historical, current and forecasted) that is reasonably available. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Applying the practical expedient in ASC 606, CRA does not assess whether a significant financing component exists if the period between when it performs its obligations under the contract and when the customer pays is one year or less. None of CRA's contracts contained a significant financing component as of June 30, 2018.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised consulting services underlying each performance obligation. CRA determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, CRA estimates the standalone selling price considering all available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

Contracts are often modified to account for changes in project scope. Contract modifications exist when the modification either creates new or changes the existing enforceable rights and obligations. Generally, contract modifications for consulting services are not distinct from the existing contract as the modification expands CRA's consulting services and thus are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue on a cumulative catch-up basis.

Consulting services revenue is generally recognized over time as the services are delivered to the customer based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the consulting services to be provided. Depending on which better depicts the transfer of value to the customer, CRA generally measures its progress using either right-to-invoice for time and materials projects, or cost-to-cost for fixed-price projects. CRA uses the right-to-invoice measure of progress when it has a right to invoice the customer for an amount that corresponds directly with the value to the customer of its performance to date. Under the right-to-invoice measure of progress, revenues are recorded equal to the amount CRA could invoice the customer. CRA uses the cost-to-cost measure of progress when it best depicts the transfer of value to the customer which occurs as it incurs costs on its contract. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred.

The contracts CRA enters into and operates under specify whether the engagements are 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 (input method), 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 CRA's employee consultants on the engagement plus all direct expenses incurred to complete the engagement, including any amounts billed to CRA by its non-employee experts.

The following table disaggregates CRA's revenue by major business line and timing of transfer of its consulting services. Refer to Note 12 to CRA's consolidated financial statements included in the annual report on Form 10-K for fiscal 2017, which was filed with the SEC on March 12, 2018, for further detail on revenues by geographical location (in thousands).

Revenues from CRA's consulting services are recorded at the net sales price, or transaction price, which includes estimates of variable consideration for which reserves are established and result from price concessions that are expected to be extended to CRA's customers. These reserves on the variable consideration components subject to constraint are classified as reductions of accounts receivable.

These calculated estimates take into consideration CRA's historical experiences of prior period revenues which were subsequently reversed due to these price concessions. Overall, these reserves reflect CRA's best estimates of the amount of consideration to which it is entitled based on the terms of its contracts with its customers. The amount of variable consideration which is included in the transaction price may be constrained, and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from its estimates. If actual results in the future vary from its estimates, CRA adjusts these estimates, which would affect net revenue and earnings in the period such variances become known.

CRA's billed and unbilled receivables consist of receivables from a broad range of clients in a variety of industries located throughout the U.S. and in other countries. CRA performs a credit evaluation of its clients to minimize its collectability risk. Periodically, CRA will require advance payment from certain clients. However, CRA does not require collateral or other security. CRA maintains accounts receivable allowances for estimated losses and disputed amounts resulting from clients' failures to make required payments. CRA bases its estimates on historical collection experience, current trends, and credit policy. In determining these estimates, CRA examines historical write-offs of its receivables and reviews client accounts to identify any specific customer collection issues. If the financial condition of any of CRA's customers were to deteriorate, resulting in an impairment of their ability or intent to make payment, additional allowances may be required.

During the fiscal quarter and fiscal year-to-date period ended June 30, 2018, $0.8 million and $1.1 million, respectively, were recorded as a bad debt expense and reported as a component of selling, general and administrative expenses related to credit-related losses.

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):

ASC 606 requires that CRA disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied as of June 30, 2018. The guidance provides certain practical expedients that limit this requirement for (1) contracts with an original expected length of one year or less and (2) contracts for which revenue is recognized at the amount to which CRA has the right to invoice for consulting services performed. Given the nature of its business, CRA does not disclose the value of unsatisfied performance obligations as the practical expedients apply to its unsatisfied performance obligations as of June 30, 2018.

CRA defines contract assets as assets for which it has recorded revenue because it determines that it is probable that it will earn a performance based or contingent fee, but is not yet entitled to receive a fee, because certain events, such as completion of the measurement period or client approval, must occur. These contract assets are included in accounts receivable, net and unbilled services within the consolidated balance sheets. The contract assets balance was immaterial as of June 30, 2018 and December 30, 2017.

CRA defines contract liabilities as advance payments or billings to its clients for services that have not yet been performed or earned and retainers. These liabilities are recorded within deferred revenues and are recognized as services are provided. Any taxes assessed on revenues relating to services provided to clients are recorded on a net basis.

During the fiscal quarter and fiscal year-to-date period ended June 30, 2018, CRA recognized the following revenue as a result of changes in the contract liability balance (in thousands):

The timing of revenue recognition, billings and cash collections results in billed receivables, unbilled services and contract liabilities on the condensed consolidated balance sheets.

When consideration is received, or such consideration is unconditionally due from a customer prior to transferring consulting services to the customer under the terms of a contract, a contract liability is recorded. Contract liabilities are recognized as revenue after control of the consulting services are transferred to the customer and all revenue recognition criteria have been met.

Prior to the adoption of ASC 606, CRA expensed bonuses paid to its employees. Under ASC 606, bonuses are not linked or paid based on specific contract billings or revenues and therefore do not represent incremental costs of obtaining a contract with a customer. Furthermore, even if the bonuses paid were incremental, the practical expedient in ASC 340 would apply, allowing for incremental costs of obtaining contracts to be expensed as incurred if the amortization period of the assets that it otherwise would have recognized is one year or less. As such, these costs are included in both cost of services and selling, general, and administrative expenses.

CRA calculates basic and diluted earnings per common share using the two-class method. Under the two-class method, net earnings are allocated to each class of common stock and participating security as if all the net earnings for the period had been distributed. CRA's participating securities

consist of unvested share-based payment awards that contain a nonforfeitable right to receive dividends and therefore are considered to participate in undistributed earnings with common shareholders. Basic earnings per common share excludes dilution and is calculated by dividing net earnings allocable to common shares by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share is calculated by dividing net earnings allocable to common shares by the weighted-average number of common shares as of the balance sheet date, as adjusted for the potential dilutive effect of non-participating share-based awards. Net earnings allocable to participating securities were not significant for the second quarter of fiscal 2018 and fiscal 2017.

The following table presents a reconciliation from net income attributable to CRA International, Inc. to net income available to common shareholders (in thousands):

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

For the fiscal quarter and fiscal year-to-date period ended June 30, 2018, 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 22,757 and 11,379 shares, respectively. For the fiscal quarter and fiscal year-to-date period ended July 1, 2017, the anti-dilutive share based awards that were excluded from the calculation of common stock equivalents for purposes of computing diluted weighted average shares outstanding amounted to 192,504 and 56,360 shares, respectively. These share-based awards were anti-dilutive because their exercise price exceeded the average market price over the respective period.

On May 3, 2017 and February 15, 2018, CRA announced its Board of Directors authorized the repurchase of up to an additional $20.0 million and $20.0 million, respectively, of CRA's common stock. Repurchases under these programs are discretionary and CRA may make such purchases under any of these programs in the open market (including under any Rule 10b5-1 plan adopted by CRA) or in

privately negotiated transactions, in each case in accordance with applicable insider trading and other securities laws and regulations. CRA records the retirement of its repurchased shares as a reduction to common stock. During the fiscal quarter and fiscal year-to-date period ended June 30, 2018, CRA repurchased and retired 215,585 shares and 378,477 shares, respectively, under these share repurchase programs at an average price per share of $55.99 and $53.90, respectively. During the fiscal quarter and fiscal year-to-date period ended July 1, 2017, there were 389,079 shares repurchased and retired under these share repurchase programs at an average price per share of $34.63. As of June 30, 2018, there was approximately $9.1 million available for future repurchases under these programs.

On December 22, 2017, the Tax Cuts and Jobs Act (the "Tax Act") was signed into U.S. law. The Tax Act significantly changes the Internal Revenue Code of 1986, as amended. The Tax Act, among other things, includes changes to the U.S. corporate tax rate, expands limitations on the deductibility of meals and entertainment, eliminates the exception to the section 162(m) limitation on the deductibility of the compensation paid to certain executive officers for "qualified performance-based compensation," allows for the expensing of capital expenditures, migrates from a "worldwide" system of taxation to a territorial system, and includes a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. ASC Topic 740, "Accounting for Income Taxes," requires companies to recognize the effect of tax law changes in the period of enactment even though the effective date for most provisions is for tax years beginning after December 31, 2017, or in the case of certain other provisions of the law, January 1, 2018.

Given the significance of the legislation, the U.S. Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118 ("SAB 118"), which allows registrants to record provisional amounts during a one year "measurement period" similar to that used when accounting for business combinations. However, the measurement period is deemed to have ended earlier when the registrant has obtained, prepared, and analyzed the information necessary to finalize its accounting. During the measurement period, impacts of the law are expected to be recorded at the time a reasonable estimate for all or a portion of the effects can be made, and provisional amounts can be recognized and adjusted as information becomes available, prepared, or analyzed.

SAB 118 summarizes a three-step process to be applied at each reporting period to account for and disclose: (1) the effects of the change in tax law for which accounting is complete; (2) provisional amounts (or adjustments to provisional amounts) for the effects of the change in tax law where accounting is not complete, but a reasonable estimate has been determined; and (3) current or deferred tax amounts reflected in accordance with law prior to the enactment of the change in tax law because the accounting of the effects of the change in tax law are not complete and a reasonable estimate has not been determined, together with qualitative disclosure of the effects of the changes in tax law for which the accounting is not compete, the reason why the accounting is not complete, and the additional information that is needed to be obtained, prepared or analyzed in order to complete the accounting. CRA is applying the guidance in SAB 118 when accounting for the enactment-date effects of the Tax Act. As of June 30, 2018, CRA has not completed its accounting for all the tax effects of the Tax Act; however, in certain cases, as described below, aspects of accounting are complete. Additionally, CRA

has made a reasonable estimate of other effects. As further discussed below, during the fiscal year-to-date period ended June 30, 2018, CRA recognized an adjustment of $0.3 million to the provisional amounts recorded at December 30, 2017 and included this adjustment as a component of income tax expense from continuing operations. In all cases, CRA will continue to make and refine its calculations as additional analysis is completed. CRA's estimates may also be affected as it gains a more thorough understanding of the tax law. These changes could be material to income tax expense.

Deferred tax assets and liabilities: In response to the Tax Act, CRA remeasured its U.S. related deferred tax assets and liabilities based on the expected rates at which they may reverse in the future, which is generally 21%. CRA recorded a provisional amount of $3.6 million as of December 30, 2017 related to the remeasurement of its deferred tax balances. Upon refinement of its calculations during the fiscal year-to-date period ended June 30, 2018, CRA adjusted its provisional amount by $0.1 million. Additionally, as a result of anticipated guidance in connection with the deductibility of compensation paid to certain executive officers for "qualified performance-based compensation," CRA recorded a provisional amount of $0.2 million which resulted in a 2.5% increase to the quarterly effective tax, raising it from 27.3% to 29.8%. Both adjustments were included as a component of income tax expense from continuing operations. CRA will continue to analyze and refine its calculations related to deferred tax balances.

The Tax Act includes a one-time mandatory repatriation transition tax on the net accumulated earnings and profits of a U.S. taxpayer's foreign subsidiaries. At December 30, 2017, CRA did not record any transition tax liability as it is in an accumulated deficit position with respect to its foreign subsidiaries based on its earnings and profits ("E&P") analysis. CRA considers its accounting for the transition tax to be complete.

The Tax Act subjects a U.S. shareholder to current tax on global intangible low-taxed income ("GILTI") earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740 No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI resulting from those items in the year the tax is incurred. Given the complexity of the GILTI provisions, CRA is still evaluating the effects of the GILTI provisions and has not yet determined its accounting policy. As of the June 30, 2018 reporting period, CRA has included GILTI associated with current-year operations solely within the estimated annual effective tax rate ("EAETR") and has not provided additional GILTI on deferred items.

The Tax Act allows U.S. Corporations to take a deduction related to its foreign-derived intangible income ("FDII") produced in the U.S. CRA expects to be able to take FDII deduction for the fiscal year ended December 29, 2018. CRA has made sufficient progress in its calculations to reasonably estimate the effect on its estimated annual effective tax rate but will continue to refine its calculations, which may result in changes to this amount.

CRA's effective income tax rates were 29.8% and 34.0% for the second quarter of fiscal 2018 and fiscal 2017, respectively. The effective tax rate for the second quarter of fiscal 2018 was lower than the prior year primarily due to a lower statutory U.S. corporate tax rate of 21% as well as an increased tax

benefit on stock-based compensation related to the adoption of ASU 2016-09. This was partially offset by higher non-deductible items in fiscal 2018 as a result of the Tax Act stemming from new limitations on the deductibility of compensation paid to executive officers and the deductibility of meals and entertainment, coupled with an immaterial discrete benefit recorded in fiscal 2017 that was nonrecurring in fiscal 2018. The effective tax rate in the second quarter of fiscal 2018 was higher than the combined federal and state statutory tax rate primarily due to the non-deductible items referenced above as a result of the Tax Act, partially offset by the tax benefit on stock-based compensation related to the adoption of ASU 2016-09. The effective tax rate in the second quarter of fiscal 2017 was lower than the combined federal and state statutory tax rate primarily due to a favorable geographical mix of earnings as well as the tax benefit related to stock-based compensation and the tax implications associated with the reversal of contingent consideration recorded as discrete items during the quarter.

CRA's effective income tax rates were 25.1% and 36.0% for the first half of fiscal 2018 and fiscal 2017, respectively. The effective tax rate for the first half of fiscal 2018 was lower than the prior year primarily due to a lower statutory U.S. corporate tax rate of 21% as well as an increased tax benefit on stock-based compensation related to the adoption of ASU 2016-09, partially offset by higher non-deductible items as a result of the Tax Act stemming from new limitations on the deductibility of compensation paid to executive officers and the deductibility of meals and entertainment. The effective tax rate in the first half of fiscal 2018 was lower than the combined federal and state statutory tax rate primarily due to the tax benefit on stock-based compensation related to the adoption of ASU 2016-09, partially offset by non-deductible items referenced above as a result of the Tax Act. The effective tax rate in the first half of fiscal 2017 was lower than the combined Federal and state statutory tax rate primarily due to a favorable geographical mix of earnings, as well as the tax benefit related to stock-based compensation and the tax implications associated with the reversal of contingent consideration.

During fiscal 2016, an examination by the Internal Revenue Service for fiscal 2014 commenced. During the second quarter of fiscal 2018, the IRS exam concluded with no changes made to CRA's fiscal 2014 tax liability. As a result, CRA recognized previously unrecognized gross tax benefits of approximately $209 thousand.

CRA has not provided for deferred income taxes or foreign withholding taxes on undistributed earnings and other basis differences that may exist from its foreign subsidiaries as of June 30, 2018 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 in the U.S. to fund its U.S. operational and strategic needs. If CRA were to repatriate its foreign earnings that are indefinitely reinvested, it would accrue substantially no additional tax expense.

CRA is subject to legal actions arising in the ordinary course of business. In management's opinion, CRA has adequate legal defenses and/or insurance coverage with respect to the eventuality of such actions. CRA does not believe any settlement or judgment relating to any pending legal action would materially affect its financial position or results of operations.

During the first quarter of fiscal 2018, CRA discovered the December 30, 2017 balances of deferred compensation and other non-current liabilities of $20.7 million and deferred rent and facility-related non-current liabilities of $11.5 million had been transposed. These immaterial offsetting errors had a net effect of $0 on non-current liabilities and total liabilities and have been revised as follows in the presentation of the December 30, 2017 balance sheet in this quarterly report on Form 10-Q (in thousands):

During the second quarter of fiscal 2018, CRA discovered that the accounts receivable and unbilled services allowances presented on the December 30, 2017 consolidated balance sheet required adjustment. These adjustments in disclosure are immaterial and had no effect on the amounts of accounts receivable and unbilled services presented on the December 30, 2017 consolidated balance sheet (in thousands):

As a result of the adjustment to the accounts receivable allowance, the following classification changes were required within the operating activities portion of the July 1, 2017 consolidated statement of cash flows (in thousands):

On August 2, 2018, CRA announced that its Board of Directors declared a quarterly cash dividend of $0.17 per share of CRA's common stock, payable on September 21, 2018 to shareholders of record as of August 28, 2018.

During the month of July 2018, CRA repaid $7.5 million in the U.S. and £2.5 million in the U.K. on its existing borrowings under its revolving line of credit. After these repayments, $10 million of borrowings remain outstanding in the U.S.

In July 2018, CRA received the GNU final distribution in the amount of $56 thousand in accordance with the asset purchase agreement.

The Investor Relations page of our website provides a link to a web page where you can obtain a copy of our code of business conduct and ethics applicable to our principal executive officer, principal financial officer, and principal accounting officer.

The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the U.S. ("U.S. GAAP"). The preparation of these financial statements requires us to make significant estimates and judgments that affect the reported amounts of assets and liabilities, as well as the related disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates in these condensed consolidated financial statements include, but are not limited to, allowances for accounts receivable and unbilled services, revenue recognition on fixed price contracts, depreciation of property and equipment, share-based compensation, valuation of acquired intangible assets, impairment of long lived assets, goodwill, accrued and deferred income taxes, valuation allowances on deferred tax assets, accrued compensation, 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 2017, which was filed with the SEC on March 12, 2018. 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 2017 for a detailed description of these policies and their potential effects on our results of operations and financial condition.

Except for the adoption of ASC 606, we did not adopt any changes in the first half of fiscal 2018 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 2018 that changed these critical accounting policies.

We adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASC 606) on January 1, 2018, using the modified retrospective method for all contracts not completed as of the date of adoption. The reported results for fiscal 2018 reflect the application of ASC 606 guidance while the reported results for fiscal 2017 were prepared under the guidance of ASC 605, Revenue Recognition (ASC 605). The cumulative effect of applying ASC 606 to all contracts with customers that were not completed as of December 30, 2017 amounted to $0.4 million.

Fiscal Quarter Ended June 30, 2018 Compared to the Fiscal Quarter Ended July 1, 2017

Revenues. Revenues increased by $11.9 million, or 12.7%, to $105.5 million for the second quarter of fiscal 2018 from $93.6 million for the second quarter of fiscal 2017. The increase in net revenue was a result of an increase in gross revenues of $11.7 million as compared to the second quarter of fiscal 2017, while write-offs and reserves decreased by $0.2 million compared to the second quarter of 2017. Included in revenues are the effect of changes in currency exchange rates of an increase of $1.2 million and a decrease of $1.8 million for the second quarters of fiscal 2018 and 2017, respectively. Utilization increased to 79% for the second quarter of fiscal 2018 from 76% for the second quarter of fiscal 2017, while consultant headcount grew modestly from 600 at the end of the second quarter of fiscal 2017 to 628 at the end of the second quarter of fiscal 2018. Billable hours increased by 9.9% for the second quarter of fiscal 2018 when compared to the second quarter of fiscal 2017.

Overall, revenues outside of the U.S. represented approximately 19% of total revenues for the second quarter of fiscal 2018 compared with approximately 20% of total revenues for the second quarter of fiscal 2017. Revenues derived from fixed-price engagements decreased to 20% of total revenues for the second quarter of fiscal 2018 compared with 30% of total revenues for the second quarter of fiscal 2017. These percentages of revenue derived from fixed-price engagements depend largely on the proportion of our revenues derived from our management consulting business, which typically has a higher concentration of fixed-price service contracts.

Costs of Services (exclusive of depreciation and amortization). Costs of services (exclusive of depreciation and amortization) increased by $4.5 million, or 6.9%, to $69.7 million for the second quarter of fiscal 2018 from $65.2 million for the second quarter of fiscal 2017. The increase in costs of services was due primarily to an increase of $2.0 million in employee compensation and fringe benefit costs attributable to salaries and benefits associated with our increased consulting headcount, an increase in forgivable loan amortization of $1.3 million and an increase in incentive and retention compensation costs of $2.5 million, offset by a decrease in stock compensation expense of $0.3 million and decrease in the valuation of the contingent consideration of $2.3 million, of which $1.7 million relates to a decrease in valuation of the contingent consideration liability during the second quarter of fiscal 2018 compared to an increase of $0.6 million in the valuation of the contingent consideration liability during the second quarter of fiscal 2017. Additionally, client reimbursable expenses increased by $1.4 million in the second quarter of fiscal 2018 compared to the second quarter of fiscal 2017. As a percentage of revenues, costs of services (exclusive of depreciation and amortization) decreased to 66.0% for the second quarter of fiscal 2018 from 69.7% for the second quarter of fiscal 2017.

Selling, General and Administrative Expenses. Selling, general and administrative expenses increased by $3.4 million, or 16.7%, to $23.7 million for the second quarter of fiscal 2018 from $20.3 million for the second quarter of fiscal 2017. A significant contributor to this increase was a $0.6 million increase in employee and incentive compensation, $1.4 million increase in other operating expenses due to increased travel and entertainment costs and professional services fees, a $0.7 million increase in rent expense due to additional leased space in our San Francisco, Chicago and London offices, as well as an increase in commissions to our nonemployee experts of $1.2 million for the second quarter of fiscal 2018 as compared to the second quarter of fiscal 2017, as a higher percentage of our revenue for the quarter was sourced by our nonemployee experts. Offsetting these increases was a decrease of $0.5 million in impairment charges related to customer relationship intangibles in fiscal 2017.

As a percentage of revenues, selling, general and administrative expenses increased slightly to 22.5% for the second quarter of fiscal 2018 from 21.7% for the second quarter of fiscal 2017 due primarily to the aforementioned increase in selling, general and administrative expenses, somewhat offset by the effect of an increase in revenues in the second quarter of fiscal 2018 as compared with the second quarter of fiscal 2017. Commissions to our nonemployee experts increased slightly to 3.3% of

revenues for the second quarter of fiscal 2018 compared to 2.4% of revenues for the second quarter of fiscal 2017.

Provision for Income Taxes. The income tax provision was $2.9 million and the effective tax rate was 29.8% for the second quarter of fiscal 2018 compared to $2.0 million and 34.0% for the second quarters of fiscal 2017. The effective tax rate for the second quarter of fiscal 2018 was lower than the prior year primarily due to a lower statutory US corporate tax rate of 21% as well as an increased tax benefit related to stock-based compensation resulting from the adoption of ASU 2016-09. This was partially offset by higher non-deductible items in fiscal 2018 as a result of the Tax Act stemming from new limitations on the deductibility of compensation paid to executive officers and the deductibility of meals and entertainment, coupled with a discrete benefit recorded in fiscal 2017 that was nonrecurring in fiscal 2018. The effective tax rate in the second quarter of fiscal 2018 was higher than the combined federal and state statutory tax rate primarily due to the non-deductible items referenced above as a result of the Tax Act, partially offset by the tax benefit on stock-based compensation related to the adoption of ASU 2016-09. The effective tax rate in the second quarter of fiscal 2017 was lower than the combined federal and state statutory tax rate primarily due to a favorable geographical mix of earnings as well as the tax benefit related to stock-based compensation and the tax implications associated with the reversal of contingent consideration recorded as discrete items during the quarter.

Net Income Attributable to CRA International, Inc. Net income attributable to CRA International, Inc. increased by $3.0 million to $6.8 million for the second quarter of fiscal 2018 from $3.8 million for the second quarter of fiscal 2017. The net income per diluted share was $0.79 per share for the second quarter of fiscal 2018, compared to $0.44 of net income per diluted share for the second quarter of fiscal 2017. Weighted average diluted shares outstanding decreased by approximately 68,000 shares to approximately 8,550,000 shares for the second quarter of fiscal 2018 from approximately 8,618,000 shares for the second quarter of fiscal 2017. The decrease in weighted average diluted shares outstanding was primarily due to the repurchase and retirement of shares of our common stock since July 1, 2017, offset in part by an increase related to our share-based compensation awards.

Fiscal Year-to-Date Period Ended June 30, 2018 Compared to the Fiscal Year-to-Date Period Ended July 1, 2017

Revenues. Revenues increased by $23.3 million, or 12.8%, to $205.0 million for the fiscal year-to-date period ended June 30, 2018 from $181.7 million for the fiscal year-to-date period ended July 1, 2017. The increase in net revenue was a result of an increase in gross revenues of $24.0 million as compared to the first half of fiscal 2017, offset by an increase in write-offs and reserves of $0.8 million as compared to the first half of fiscal 2017. Included in revenues are the effect of changes in currency exchange rates of an increase of $3.4 million and a decrease of $3.9 million for the second quarters of fiscal 2018 and 2017, respectively. Utilization increased to 76% for the first half of fiscal 2018 from 74% for the first half of fiscal 2017, while consultant headcount declined modestly during the first half of fiscal 2018.

Overall, revenues outside of the U.S. represented approximately 20% and 19% of total revenues for the fiscal year-to-date period ended June 30, 2018 and the fiscal year-to-date period ended July 1, 2017, respectively. Revenues derived from fixed-price engagements were 20% and 26% of total revenues for the fiscal year-to-date period ended June, 2018 and the fiscal year-to-date period ended July 1, 2017, respectively. These percentages of revenue derived from fixed-price engagements depend largely on the proportion of our revenues derived from our management consulting business, which typically has a higher concentration of fixed-price service contracts.

Costs of Services (exclusive of depreciation and amortization). Costs of services (exclusive of depreciation and amortization) increased by $11.3 million, or 8.8%, to $139.1 million for the fiscal year-to-date period ended June 30, 2018 from $127.8 million for the fiscal year-to-date period ended

July 1, 2017. The increase in costs of services was due primarily to an increase of $4.9 million in employee compensation and fringe benefit costs attributable to salaries and benefits associated with our increased consulting headcount, primarily attributable to the C1 acquisition, an increase in incentive and retention compensation costs of $5.1 million, and an increase in forgivable loan amortization of $1.0 million, offset by a decrease in stock compensation expense of $0.7 million and a decrease in the valuation of the contingent consideration of $2.4 million of which $1.8 million relates to a decrease in valuation of the contingent consideration liability during the fiscal year-to-date period ended June 30, 2018 compared to an increase of $0.6 million in the valuation of the contingent consideration liability during the fiscal year-to-date period ended June 30, 2017. Additionally, client reimbursable expenses increased by $3.5 million in the first half of fiscal 2018 compared to the first half of fiscal 2017. As a percentage of revenues, costs of services (exclusive of depreciation and amortization) decreased to 67.8% for the first half of fiscal 2018 from 70.3% for the first half of fiscal 2017.

Selling, General and Administrative Expenses. Selling, general and administrative expenses increased by $6.4 million, or 16.4%, to $45.4 million for the first half of fiscal 2018 from $39.0 million for the first half of fiscal 2017. The primary contributors to this increase were an increase in employee and incentive compensation of $1.0 million, a $1.8 million increase in other operating expenses due to increased travel and entertainment costs and professional services fees, $2.4 million increase in rent and operating costs due additional space in our New York, San Francisco, Chicago and London offices, as well as an increase in commissions to our nonemployee experts of $1.5 million for the first half of fiscal 2018 as compared to the first half of fiscal 2017, as a higher percentage of our revenue for the quarter was sourced by our nonemployee experts.

As a percentage of revenues, selling, general and administrative expenses increased to 22.1% for the fiscal year-to-date period ended June 30, 2018 from 21.4% for the fiscal year-to-date period ended July 1, 2017 due primarily to the increase in revenues. Commissions to our nonemployee experts increased to 3.2% of revenues for the fiscal year-to-date period ended June 30, 2018 compared to 2.8% of revenues for the fiscal year-to-date period ended July 1, 2017 as less revenue was sourced by nonemployee experts in the first half of fiscal 2017 compared to the first half of fiscal 2018.

GNU Gain on Sale of Business Assets. On April 13, 2016, a buyer acquired substantially all of the business assets and assumed substantially all of the liabilities of GNU for a purchase price of $1.35 million. Of this amount, $1.1 million was received at closing, and the remaining $0.25 million was paid in full on May 3, 2017. GNU recognized a gain on sale of its business assets of $0.25 million during the second quarter of fiscal 2017, of which $0.14 million is attributed to CRA.

Provision for Income Taxes. For the first half of fiscal 2018, our income tax provision was $3.9 million, and the effective tax rate was 25.1%, compared to a provision of $3.8 million and an effective tax rate of 36.0% for the first half of fiscal 2017. The effective tax rate for the first half of fiscal 2018 was lower than the prior year primarily due to a lower statutory U.S. corporate tax rate of 21% as well as an increased tax benefit on stock-based compensation related to the adoption of ASU 2016-09, partially offset by higher non-deductible items as a result of the Tax Act stemming from new limitations on the deductibility of compensation paid to executive officers and the deductibility of meals and entertainment. The effective tax rate in the first half of fiscal 2018 was lower than the combined federal and state statutory tax rate primarily due to the tax benefit on stock-based compensation related to the adoption of ASU 2016-09, partially offset by non-deductible items referenced above as a result of the Tax Act. The effective tax rate in the first half of fiscal 2017 was lower than the combined federal and state statutory tax rate primarily due to a favorable geographical mix of earnings, as well as the tax benefit related to stock-based compensation and the tax implications associated with the reversal of contingent consideration.

Net Income Attributable to CRA International, Inc. Net income attributable to CRA International, Inc. increased by $5.0 million to $11.7 million for the fiscal year-to-date period ended

June 30, 2018 from $6.7 million for the fiscal year-to-date period ended July 1, 2017. The diluted net income per share was $1.35 for the fiscal year-to-date period ended June 30, 2018, compared to diluted net income per share of $0.77 for the fiscal year-to-date period ended July 1, 2017. Diluted weighted average shares outstanding increased by approximately 30,000 to approximately 8,649,000 shares for the fiscal year-to-date period ended June 30, 2018 from approximately 8,619,000 shares for the fiscal year-to-date period ended July 1, 2017.

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

General. In the fiscal year-to-date period ended June 30, 2018, cash and cash equivalents decreased by $45.0 million. We completed the period with cash and cash equivalents of $9.0 million and working capital (defined as current assets less current liabilities) of $36.6 million. The principal drivers of the reduction of cash was payment of a significant portion of our fiscal 2017 performance bonuses in the first half of 2018, the repurchase of shares, the funding of forgivable loans and the buildout costs of our New York, San Francisco, Chicago and London offices.

Of the total cash and cash equivalents of $9.0 million at June 30, 2018, $3.2 million was held within the U.S. We have sufficient sources of liquidity in the U.S., including cash from operations and availability on our revolving line of credit, to fund U.S. activities. At June 30, 2018, we had outstanding borrowings on the revolving line of credit of $20.8 million, which is expected to be paid within 12 months of borrowing.

Sources and Uses of Cash. During the fiscal year-to-date period ended June 30, 2018, net cash used in operating activities was $32.8 million. Net income was $11.7 million for the fiscal year-to-date period ended June 30, 2018. The primary factor in cash used in operations was the decrease in the "accounts payable, accrued expenses, and other liabilities" line item of the statement of cash flows of $31.3 million due to the payment of a significant portion of our fiscal 2017 performance bonuses during the first half of fiscal 2018. Other uses of cash included an increase of $9.9 million in accounts receivable, an increase of $5.0 million in unbilled receivables and an increase of $12.1 million in forgivable loans. The change in forgivable loans for the period of $12.1 million was primarily driven by $19.3 million of forgivable loan issuances, net of repayments, as well as an increase of $0.4 million of foreign currency exchange, offset by $7.6 million of forgivable loan amortization. Offsetting these uses of cash was a $0.4 million decrease in the prepaid expenses and other current assets, and other assets and a $1.5 million decrease in incentive cash awards. Cash provided by operations included non-cash items including depreciation and amortization expense of $4.7 million and share-based compensation expenses of $2.4 million.

During the fiscal year-to-date period ended June 30, 2018, net cash used in investing activities was $8.9 million for capital expenditures.

During the fiscal year-to-date period ended June 30, 2018, net cash used in financing activities was $2.8 million, primarily as a result of borrowings under the revolving line of credit of $30.2 million and $0.9 million received upon the issuance of shares of common stock related to the exercise of stock options. Offsetting these increases in cash were the tax withholding payments reimbursed by restricted shares of $1.8 million, payment of $2.8 million of cash dividends to shareholders, repayment of $8.8 million under the revolving line of credit, and $20.4 million of repurchases of common stock.

We are party to a credit agreement that provides us with a $125.0 million revolving credit facility and a $15.0 million sublimit for the issuance of letters of credit. We may use the proceeds of the revolving credit facility to provide working capital and for other general corporate purposes. Generally, we may repay any borrowings under the revolving credit facility at any time, but must repay all borrowings no later than October 24, 2022. There was $20.8 million in outstanding borrowings under this revolving line of credit as of June 30, 2018. During the month of July 2018, we repaid $7.5 million in the U.S. and £2.5 million in the U.K. After these repayments, $10 million of borrowings remain outstanding in the U.S. The remaining borrowings are expected to be repaid over the next 12 months in accordance with the terms of the agreement.

The amount available under this revolving line of credit is reduced by certain letters of credit outstanding, which amounted to $3.9 million as of June 30, 2018. Borrowings under the revolving credit facility bear interest at a rate per annum, at our election, of either (i) the adjusted base rate, as defined in the credit agreement, plus an applicable margin, which varies between 0.25% and 1.25% 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 1.25% and 2.25% 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 0.20% and 0.35% depending on our total leverage ratio. Borrowings under the revolving credit facility are secured by 100% of the stock of certain of our U.S. subsidiaries and 65% of the stock of certain of our foreign subsidiaries, which represent approximately $28.2 million in net assets as of June 30, 2018.

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

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

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

to fund these payments, if any, from existing cash resources, cash generated from operations, or borrowings on our existing revolving credit facility.

As part of our business, we regularly evaluate opportunities to acquire other consulting firms, practices or groups or other businesses. In recent years, we have typically paid for acquisitions with cash, or a combination of cash and our common stock, and we may continue to do so in the future. To pay for an acquisition, we may use cash on hand, cash generated from our operations, borrowings under our revolving credit facility, or we may pursue other forms of financing. Our ability to secure short-term and long-term debt or equity financing in the future, including our ability to refinance our current senior loan agreement, will depend on several factors, including our future profitability, the levels of our debt and equity, restrictions under our existing revolving line of credit with our bank, and the overall credit and equity market environments. See Note 6 to our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for further details of the C1 acquisition in 2017.

On May 3, 2017 and February 15, 2018, we announced our Board of Directors approved share repurchase programs of up to $20.0 million, and $20.0 million, respectively, of our common stock. We may repurchase shares under these programs in open market purchases (including through any Rule 10b5-1 plan adopted by us) or in privately negotiated transactions in accordance with applicable insider trading and other securities laws and regulations. During the fiscal quarter and fiscal year-to-date period ended June 30, 2018, we repurchased and retired 215,585 shares and 378,477 shares, respectively, under these share repurchase programs at an average price per share of $55.99 and $53.90, respectively. During the fiscal quarter and fiscal year-to-date period ended July 1, 2017, we repurchased and retired 389,079 shares under these share repurchase programs at an average price per share of $34.63. As of June 30, 2018, there was approximately $9.1 million available for future repurchases under these programs. We will finance these programs with available cash, cash from future operations and funds from our existing revolving credit facility. We expect to continue repurchasing shares under these programs.

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

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

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

The hiring of individuals to replenish and expand our employee base is an essential part of our business operations and has historically been funded principally from operations. Many of the other above activities are discretionary in nature. For example, capital expenditures can be deferred, acquisitions can be forgone, and share repurchase programs and regular dividends can be suspended. As such, our operating model provides flexibility with respect to the deployment of cash flow from operations. Given this flexibility, we believe that our cash flows from operations, supplemented by cash on hand and borrowings under our bank credit facility (as necessary), will provide adequate cash to fund our cash needs from normal operations for at least the next 12 months.

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

On August 16, 2017, we entered into a second amendment to our lease with BP Hancock LLC, as landlord, for our office space located at 200 Clarendon Street, Boston, Massachusetts. Under the amendment, we will lease 28,757 square feet of office space on the building's 11^th floor, in addition to the 67,659 square feet of office space we currently lease on the building's 9th, 10th and 25th floors. The landlord expects to deliver possession of the new space on or before April 1, 2019. If we do not have possession of the new space by April 1, 2020 and certain other conditions are not satisfied, the amendment gives us a right to terminate the lease with respect to the space on the 11th floor. The

amendment also extends the base term of the lease for an additional five years ending on July 31, 2030. Beginning six months after the landlord delivers possession of the new space on the 11^th floor to us or, if earlier, when we commence operations in the new space, the annual base rent for the new space through the end of the lease's base term, exclusive of customary operating costs and expenses, will be approximately $1.9 million per year, subject to annual increases of approximately 1.7% per year. Beginning on August 1, 2025, the annual fixed rent for the 9th and 10th floors will be payable at the same rate per square foot then in effect for the 11th floor. The amendment includes a tenant improvement allowance of approximately $2.9 million. Subject to certain conditions, the lease will be extendable for two additional five-year periods. The amendment also gives us the right to terminate our lease of 10,057 square feet of office space on the building's 25^th floor effective as of the date on which we begin paying rent for the 11th floor. On May 24, 2018, we notified the landlord of our intent to terminate the lease of the 25^th floor effective as of the rent commencement date of the second amendment, which is expected to occur on or before October 1, 2019.

On June 27, 2018, we entered into a third amendment to our lease with BP Hancock LLC for an additional 14,097 square feet of office space on the 12^th floor of our Boston office building. The landlord expects to deliver possession of the new space on or before May 1, 2019. If we do not have possession of the new space on the 12^th floor by May 1, 2020 and certain other conditions are not satisfied, the amendment gives us a right to terminate the lease with respect to the new space. The third amendment is coterminous with the lease for the 9^th, 10^th and 11^th floors, ending on July 31, 2030. Beginning six months after the landlord delivers possession of the new space on the 12^th floor to us or, if earlier, when we commence operations in the new space, the annual base rent for the new space through the end of the lease's base term, exclusive of customary operating costs and expenses, will be approximately $1.0 million per year, subject to annual increases of approximately 1.6% per year. The amendment includes a tenant improvement allowance of approximately $1.2 million. The amendment also gives us a right of first offer to rent certain additional office space in the building if it becomes available.

Important factors that could cause our actual results to differ materially from the forward-looking statements we make in this Quarterly Report on Form 10-Q, as well as a description of material risks we face, are set forth under the heading "Risk Factors" included in Part I—Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 30, 2017 filed with the SEC on March 12, 2018. If any of these risks, or any risks not presently known to us or that we currently believe are not significant, develops into an actual event, then our business, financial condition, and results of operations could be adversely affected.

For information regarding our exposure to certain market risks see "Item 7A. Quantitative and Qualitative Disclosures about Market Risk," in our Annual Report on Form 10-K for the fiscal year ended December 30, 2017 filed with the SEC on March 12, 2018.

Under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. This is done in order to ensure that information we are required to disclose in the reports that are filed or submitted under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and

reported within the time periods specified in the SEC's rules and forms. Based upon that evaluation, our President and Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of June 30, 2018, due to the material weaknesses in internal control over financial reporting related to the inadequate design and execution of controls over non-routine technical accounting matters and information technology general controls ("ITGC") related to program changes to our accounting software. In addition, despite the significant efforts made during the fiscal year ended December 30, 2017 to remediate our previously identified material weaknesses, the material weakness in internal controls over ITGC prevented us from remediating the material weaknesses in internal controls over financial reporting in respect of revenue and related reserve processes and compensation-related processes described in Item 9A of our Annual Report on Form 10-K for the fiscal year ended December 30, 2017.

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

Under the supervision and with the participation of our management, including our President and Chief Executive Officer and Chief Financial Officer, we evaluated whether there were any changes in our internal control over financial reporting during the first half of fiscal 2018. Except for the ongoing remediation of the material weaknesses in internal controls over financial reporting noted above pursuant to the plans described in Item 9A of our Annual Reports on Form 10-K for the fiscal years ended December 31, 2016 and December 30, 2017, respectively, 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 2018, except those disclosed below, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

On December 31, 2017, we implemented ASC 606, Revenue from Contracts with Customers. Although the new revenue standard did not have a material impact on our ongoing net income, we did implement changes to our processes related to revenue recognition and the control activities within them. These included the development of new policies based on the five-step model provided in the new revenue standard, new training, ongoing contract review requirements, and gathering of information provided for disclosures.

We are committed to remediating the control deficiencies that gave rise to the material weaknesses described above. Management is responsible for implementing changes and improvements to our internal control over financial reporting and for remediating the control deficiencies that gave rise to these material weaknesses. During fiscal 2018, we have enhanced our system of internal controls over financial reporting with the following actions:

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

There has been no material change in any risk factors previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 30, 2017 filed with the SEC on March 12, 2018. See "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 30, 2017 for a complete description of the material risks we face.

(c) The following table provides information about our repurchases of shares of our common stock during the fiscal quarter ended June 30, 2018. 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 2018.
