Special Note on Factors Affecting Future Results

This Quarterly Report on Form 10-Q contains forward-looking statements regarding future events and the future results of Charles River Laboratories International, Inc. that are based on our current expectations, estimates, forecasts, and projections about the industries in which we operate and the beliefs and assumptions of our management. Words such as “expect,” “anticipate,” “target,” “goal,” “project,” “intend,” “plan,” “believe,” “seek,” “estimate,” “will,” “likely,” “may,” “designed,” “would,” “future,” “can,” “could” and other similar expressions that are predictions of or indicate future events and trends or which do not relate to historical matters are intended to identify such forward-looking statements. These statements are based on our current expectations and beliefs and involve a number of risks, uncertainties, and assumptions that are difficult to predict. For example, we may use forward-looking statements when addressing topics such as: goodwill and asset impairments still under review; future demand for drug discovery and development products and services, including the outsourcing of these services and spending trends by our clients; our expectations regarding stock repurchases, including the number of shares to be repurchased, expected timing and duration, the amount of capital that may be expended and the treatment of repurchased shares; present spending trends and other cost reduction activities by our clients; future actions by our management; the outcome of contingencies; changes in our business strategy; changes in our business practices and methods of generating revenue; the development and performance of our services and products; market and industry conditions, including competitive and pricing trends; our strategic relationships with venture capital limited partnerships and leading pharmaceutical companies and opportunities for future similar arrangements; changes in the composition or level of our revenues; our cost structure; the impact of acquisitions (including BioFocus and Argenta, see Note 2, "Business Acquisitions"); the impact of dispositions; our expectations with respect to revenue growth and operating synergies (including the impact of specific actions intended to cause related improvements); the impact of specific actions intended to improve overall operating efficiencies and profitability (and our ability to accommodate future demand with our infrastructure) including gains and losses attributable to businesses our plans to close, consolidate or divest; changes in our expectations regarding future stock option, restricted stock, performance share units and other equity grants to employees and directors; expectations with respect to foreign currency exchange; assessing (or changing our assessment of) our tax positions for financial statement purposes; and our liquidity. In addition, these statements include the impact of economic and market conditions on our clients; the effects of our cost-saving actions and the steps to optimize returns to shareholders on an effective and timely basis and our ability to withstand the current market conditions. You should not rely on forward-looking statements because they are predictions and are subject to risks, uncertainties and assumptions that are difficult to predict. Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this document or in the case of statements incorporated by reference, on the date of the document incorporated by reference. Factors that might cause or contribute to such differences include, but are not limited to, those discussed in our Annual Report on Form 10-K for the year ended December 28, 2013 under the section entitled “Our Strategy,” the section entitled “Risks Related to Our Business and Industry,” the section entitled “Management's Discussion and Analysis of Financial Condition and Results of Operations” and in our press releases and other financial filings with the Securities and Exchange Commission. We have no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or risks. New information, future events or risks may cause the forward-looking events we discuss in this report not to occur.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

(in thousands, except share and per share amounts)

1. BASIS OF PRESENTATION

The condensed consolidated interim financial statements of Charles River Laboratories International, Inc. (the Company) are unaudited, and certain information and footnote disclosures related thereto normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) have been omitted in accordance with Rule 10-01 of Regulation S-X. In the opinion of management, the accompanying unaudited condensed consolidated financial statements were prepared following the same policies and procedures used in the preparation of the audited financial statements and reflect all adjustments (consisting of normal recurring adjustments) considered necessary to state fairly the Company's financial position and results of operations. The results of operations for the interim periods are not necessarily indicative of the results for the entire fiscal year. These condensed consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 28, 2013. Certain reclassifications have been made to prior periods' financial statements to conform with the current period presentation.

During the quarter ended June 28, 2014, the Company revised its reportable segments to ensure alignment with the Company's view of the business following its acquisition of the contract research organization (CRO) services division of Galapagos N.V. (Early Discovery). The Company reviewed the new and existing markets addressed by the business, the recently revised go-to-market strategy, long-term operating margins, the discrete financial information available to its Chief Operating Decision Maker (CODM) and considered how its businesses aggregate based on these qualitative and quantitative factors. Based on this review, the Company identified three reportable segments: Research Models and Services (RMS), Discovery and Safety Assessment (DSA) and Manufacturing Support (Manufacturing). The Company will report segment results on this basis beginning in the quarter ended June 28, 2014 and retrospectively for all comparable prior periods.

The revised reportable segments are as follows:

Research Models and Services	Discovery and Safety Assessment	Manufacturing Support
Research Models	Discovery Services (1)	Endotoxin and Microbial Detection
Research Model Services (2)	Safety Assessment	Avian Vaccine Services
		Biologics Testing Solutions

⁽¹⁾ Discovery Services includes the Early Discovery businesses, which were acquired on April 1, 2014.

⁽²⁾ Research Model Services include Genetically Engineered Models and Services (GEMS), Research Animal Diagnostic Services (RADS), and Insourcing Solutions (IS).

Prior to recasting the reportable segments, the businesses were reported in two segments as follows:

Research Models and Services	Preclinical Services
Research Models (3)	Discovery Services
Research Model Services (4)	Safety Assessment
Endotoxin and Microbial Detection	Biologics Testing Solutions

⁽³⁾ Research Models included Avian Vaccine Services.

⁽⁴⁾ Research Model Services included GEMS, RADS, IS and Discovery Research Services.

Use of Estimates

The preparation of condensed consolidated financial statements in accordance with U.S. GAAP requires that the Company makes estimates and judgments that may affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to revenue recognition, impairment of long-lived assets, equity investments, income taxes including the valuation allowance for deferred tax assets, defined benefit pension plans, contingencies and share-based compensation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of

NOTES TO UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS (Continued)

(in thousands, except share and per share amounts)

which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Changes in estimates are reflected in reported results in the period in which they become known.

Summary of Significant Accounting Policies

The Company’s significant accounting policies are described in Note 1, “Description of Business and Summary of Significant Accounting Policies,” in the 2013 Annual Report on Form 10-K.

Consolidation

The Company's condensed consolidated financial statements reflect its financial statements, those of its wholly-owned subsidiaries and those of certain variable interest entities where the Company is the primary beneficiary. For consolidated entities in which the Company owns or is exposed to less than 100% of the economics, the Company records net income (loss) attributable to noncontrolling interests in its condensed consolidated statements of income equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. Intercompany balances and transactions are eliminated in consolidation.

In determining whether the Company is the primary beneficiary of an entity and therefore required to consolidate, the Company applies a qualitative approach that determines whether it has both (1) the power to direct the economically significant activities of the entity and (2) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to that entity. The Company continuously assesses whether it is the primary beneficiary of a variable interest entity as changes to existing relationships or future transactions may result in the Company consolidating or deconsolidating certain of its variable interest entities.

Recent Accounting Pronouncements

In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The ASU is effective for annual and interim periods beginning after December 15, 2014. The Company is evaluating the impact the adoption will have on its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers."  The standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is not permitted. The ASU is effective for annual and interim periods beginning after December 15, 2016. The Company has not yet selected a transition method and is evaluating the impact the adoption will have on its consolidated financial statements and related disclosures.

2. BUSINESS ACQUISITIONS

Early Discovery

On April 1, 2014, the Company acquired Early Discovery consisting of (1) 100% of the shares of the United Kingdom (U.K.) based entities Argenta and BioFocus, and (2) certain Dutch assets. These businesses have formed the core of the Company's Early Discovery business. With this acquisition, the Company has enhanced its position as a full service, early-stage CRO, with integrated in vitro and in vivo capabilities from target discovery through preclinical development. The preliminary purchase price of the acquisition is $191,354, including $861 in contingent consideration. The acquisition was funded by cash on hand and borrowings on the Company's revolving credit facility. The purchase price includes payment for estimated working capital, which is subject to final adjustment based on the actual working capital of the acquired business. The business will be reported in the Company's DSA segment.

The contingent consideration is a one-time payment that could become payable based on the achievement of a revenue target for the twelve-month period following the acquisition. If achieved, the payment would become due in the second quarter of 2015. The aggregate, undiscounted amount of contingent consideration that the Company would pay is €5,000 ($6,825 as of June 28, 2014). The Company estimated the fair value of this contingent consideration based on a probability-weighted set of outcomes.

The goodwill resulting from the transaction of $66,330 is primarily attributed to the potential growth in the Company's DSA businesses from customers introduced through the Early Discovery business, the assembled workforce of the acquired businesses and expected cost synergies. The goodwill attributable to Argenta and BioFocus is not deductible for tax purposes. The Company incurred transaction and integration costs in connection with the acquisition of $1,574 and $4,879 during the three and six months ended June 28, 2014, respectively, which are included in selling, general and administrative expenses.

The following selected unaudited pro forma consolidated results of operations are presented as if the Early Discovery acquisition had occurred as of the beginning of the period immediately preceding the period of acquisition after giving effect to certain adjustments, including amortization of intangible assets and depreciation of fixed assets of $3,651 and other one-time costs. The pro forma data is for informational purposes only and does not necessarily reflect the results of operations had the companies operated as one entity during the periods reported. No effect has been given for synergies, if any, that may have been realized through the acquisition.

may result in the future. Early Discovery revenue and operating income for the three months ended June 28, 2014 are $23,513 and $39, respectively.

VivoPath

In June 2014, the Company acquired substantially all of the assets of VivoPath, LLC, a discovery service company specializing in the rapid, in vivo compound evaluation of molecules in the therapeutic areas of metabolism, inflammation and oncology. The preliminary purchase price of the acquisition is $2,267, including $1,567 in contingent consideration. The aggregate, undiscounted amount of contingent consideration that could become payable is a maximum of $2,400 payable over the next three years based on the achievement of revenue growth targets. The Company estimated the fair value of this contingent consideration based on a probability-weighted set of outcomes. The business will be reported in the Company's DSA segment.

3. RESTRUCTURING AND ASSET IMPAIRMENTS

Facilities

RMS Japan

In the second quarter of 2014, the Company committed to a plan to consolidate certain research model operations in Japan. As a result, the Company adjusted the carrying value of certain facilities impacted by the consolidation plan. During the second quarter of 2014, the Company recorded $440 of accelerated depreciation. The Company anticipates that additional accelerated depreciation for the second half of 2014 will amount to approximately $2,640.

RMS North America

In the first quarter of 2014, the Company committed to a plan to close its research model production facility located in Michigan by the end of the 2014 and to reassign the sourcing of research models to other facilities in the United States (U.S.). As a result of these actions, the Company reviewed the long-lived assets of this asset group, consisting of land improvements, building and equipment, for potential impairment based on the undiscounted cash flows of the group and considered the potential redeployment and future utilization of the facility's machinery and equipment. Based on the results of this analysis, during the first quarter the Company recorded an asset impairment and other charges of $690 and accelerated depreciation of$290 reflecting the adjusted remaining useful life and estimated residual value of building and improvements. During the second quarter of 2014, the Company recorded $294 of asset impairment and other charges and $293 of accelerated depreciation. The Company anticipates that additional accelerated depreciation for 2014 will amount to approximately $503.

RMS Europe

In 2012, the Company commenced a consolidation of certain research model operations in Europe. As a result, the Company adjusted the carrying value of certain facilities impacted by the consolidation plan to fair value through an asset impairment charge in 2012. In the second quarter of 2014, an update to the fair value resulted in an asset impairment charge of $312. During the first quarter of 2014, the Company entered into a purchase and sale agreement to sell a facility impacted by the consolidation plan. The sale closed in the second quarter of 2014, resulting in a gain of $1,107.

Staffing Reductions

The Company has periodically implemented staffing reductions to improve operating efficiency and profitability at various sites. As a result of these actions, for the six months ended June 28, 2014 and June 29, 2013, the Company recorded severance and retention charges as shown below. As of June 28, 2014, $2,541 was included in accrued compensation and $1,282 in other long-term liabilities on the Company's consolidated balance sheet.

5. MARKETABLE SECURITIES AND INVESTMENTS IN LIMITED PARTNERSHIPS

Marketable Securities

The Company's investments in marketable securities are reported at fair value and consist of time deposits with original maturities ranging from three months to one year. The carrying value for these time deposits approximates fair value and, accordingly, there are no unrealized gains or losses reflected on the consolidated balance sheet.

Investments in Venture Capital Limited Partnerships

The Company has invested in several venture capital limited partnerships that invest in start-up companies in the life sciences industry. The Company's total commitment to these entities as ofJune 28, 2014 is $55,000 of which the Company has funded $15,549 to date. During the three months and six months ended June 28, 2014, the Company received dividends in cash and in securities totaling $940 and $7,438, respectively. The Company's ownership interest in these limited partnerships ranges from 3.8% to 12.1%. These limited partnerships prepare quarterly financial statements following investment company accounting guidelines, whereby investments are adjusted to fair value with resulting gains and losses recorded in earnings. These entities estimate the fair value of non-publicly traded investments based on all available information, including value implied by the pricing of subsequent preferred share offerings and the net present value of future cash flows.

The Company accounts for these investments under the equity-method, whereby the Company records its portion of the investment gains and losses as reported in the fund's financial statements on a quarterly lag each reporting period. In addition, the Company adjusts the carrying value of these investments to reflect its estimate of changes to fair value since the fund's

(in thousands, except share and per share amounts)

financial statements based information from the fund's management team, market prices of known public holdings of the fund and other information.

The Company's investments in these limited partnerships are subject to a high degree of volatility and are generally higher risk relative to other investments the Company may hold. The Company reports gains and losses from its limited partnership investments in other income, net. The Company recognized gains related to these investments of $2,076 and $1,395 for the three months ended June 28, 2014 and June 29, 2013, respectively. The Company recognized gains related to these investments of $8,180 and $1,305 for the six months ended June 28, 2014 and June 29, 2013, respectively. As of June 28, 2014 and December 28, 2013, these investments had a carrying value of $21,828 and $17,911, respectively, which is reported in other assets on the consolidated balance sheets.

6. FAIR VALUE

Valuation methodologies used for assets and liabilities measured or disclosed at fair value are as follows:

• Time deposits—Valued at their carrying amount, which approximates fair value, as reported by the financial institutions that hold the Company's securities.

• Investments in life insurance policies—Valued at cash surrender value based on fair value of underlying investments.

• Redeemable noncontrolling interest—Valued primarily using the income approach based on estimated future cash flows of the underlying business based on the Company's projected financial data discounted by a weighted average cost of capital. Significant assumptions include a discount rate of 17.5% and a long-term pretax operating margin of 32%.

• Contingent consideration—Valued based on a probability-weighting of the future cash flows associated with the potential outcomes.

The fair value hierarchy level is determined by asset and liability class based on the lowest level of significant input. The observability of inputs may change for certain assets or liabilities. This condition could cause an asset or liability to be reclassified between levels. During the periods ended June 28, 2014, there were no transfers between levels.

Assets and liabilities measured at fair value on a recurring basis are summarized below:

The book value of the Company's term and revolving loans, which are variable rate loans carried at amortized cost, and approximates fair value based on current market pricing of similar debt. As the fair value is based on significant other observable inputs, including current interest and foreign currency exchange rates, it is deemed to be Level 2.

Concurrent with the acquisition of Vital River in 2013, the Company entered into a joint venture agreement with the noncontrolling interest holders that provide it with the right to purchase the remaining 25% of the entity for cash at its then appraised value beginning in January 2016. Additionally, the noncontrolling interest holders were granted the right to require the Company to purchase the remaining 25% of the entity at its then appraised value beginning in January 2016 for cash. These rights are accelerated in certain events. As the noncontrolling interest holders can require the Company to purchase for cash the remaining 25% interest, the Company classifies the carrying amount of the noncontrolling interest above the equity section and below liabilities on the consolidated balance sheet and adjust the carrying amount to fair value each quarter end. Adjustments to fair value, which is deemed to be Level 3 as the fair value is based on unobservable inputs, are recorded through additional paid-in capital.

As part of the Company's acquisitions of the Early Discovery businesses and VivoPath assets, it agreed to make cash payments upon the satisfaction of certain future financial measures. The carrying amount of these obligations is adjusted to fair value each quarter end. As the fair value is based on unobservable inputs, it is deemed to be Level 3.

The significant unobservable inputs used in the fair value measurement of the Company's contingent consideration are the probabilities of successful achievement of certain revenue targets and a discount rate. Significant increases or decreases in any of the probabilities of success would result in a significantly higher or lower fair value measurement, respectively. Significant increases or decreases in the discount rate would result in a significantly lower or higher fair value measurement, respectively.

The Company enters into derivative instruments to hedge foreign currency exchange risk to reduce the impact of changes to foreign currency rates on its financial statements. During the three months and the six months ended June 28, 2014, the Company recognized $(499) and $76 of net hedge (gains) losses associated with forward currency contracts, respectively. As of June 28, 2014, there were no open forward currency contracts.

In the second quarter of 2014, the Company revised its reportable segments to align with the view of the business following its Early Discover acquisition. See Note 1, "Basis of Presentation." As a result of this reorganization, goodwill was allocated from the Company's prior reporting units to new reporting units, as shown in the preceding table within "transfers." The allocation was based on the fair value of each business group within its original reporting unit relative to the fair value of that reporting unit. In addition, the Company completed an assessment of any potential goodwill impairment for all reporting units immediately prior to the reallocation and determined that no impairment existed.

8. LONG-TERM DEBT AND CAPITAL LEASE OBLIGATIONS

Long-Term Debt

Capital Lease Obligations

The Company acquired a build-to-suit lease as part of its acquisition of Early Discovery. The Company is the deemed owner of the asset during the construction period for accounting purposes due to its involvement during the construction period. The Company capitalized $9,698 related to this construction at June 28, 2014 along with a corresponding financing obligation of the same amount. See Note 13, "Commitments and Contingencies."

Capital lease obligations amounted to $10,753 and $740 at June 28, 2014 and December 28, 2013, respectively.

9. EQUITY

Earnings Per Share

Basic earnings per share for the three and six months ended June 28, 2014 and June 29, 2013 was computed by dividing earnings available to common shareholders for these periods by the weighted average number of common shares outstanding in the respective periods adjusted for contingently issuable shares, such as unvested restricted stock. The weighted average number of common shares outstanding for the three and six months ended June 28, 2014 and June 29, 2013 has been adjusted to include common stock equivalents for the purpose of calculating diluted earnings per share for these periods.

Options to purchase 943,484 and 2,591,555 shares were outstanding in each of the three months ended June 28, 2014 and June 29, 2013, respectively, but were not included in computing diluted earnings per share because their inclusion would have been anti-dilutive. For the six months ended June 28, 2014 and June 29, 2013, anti-dilutive options outstanding were 783,220 and 2,868,814 shares, respectively. Basic weighted average shares outstanding for the three and six months ended June 28, 2014 and June 29, 2013 excluded the weighted average impact of 1,192,859 and 1,121,561 shares, respectively, of non-vested restricted stock awards.

Treasury Shares

In July 2010, the Company's Board of Directors authorized a $500,000 stock repurchase program.  The Board of Directors subsequently approved increases to the stock repurchase program by $250,000 in 2010, and by $250,000 in 2013 for an aggregate authorization of $1,000,000.  Additionally, the Company's 2007 Incentive Plan permits the netting of common stock upon vesting of restricted stock awards in order to satisfy individual tax withholding requirements.

Share repurchases for the three and the six months ended June 28, 2014 and June 29, 2013 were as follows:

	Three Months Ended				Six Months Ended

10. INCOME TAXES

The following table provides a reconciliation of the provision for income taxes on the condensed consolidated statements of income:

	Three Months Ended				Six Months Ended
	June 28, 2014		June 29, 2013		June 28, 2014		June 29, 2013
Income from continuing operations before income taxes	50,541		36,847		93,527		72,495
Effective tax rate	27.9	%	22.3	%	26.1	%	24.7	%
Provision for income taxes	14,081		8,219		24,439		17,941

The Company's overall effective tax rate was 27.9% for the three months ended June 28, 2014 and 22.3% for the three months ended June 29, 2013. The Company's overall effective tax rate was 26.1% and 24.7% for each of the six months ended June 28, 2014 and June 29, 2013, respectively. The increases were primarily attributable to recent tax law changes, including a statutory 25% decrease in the Canadian Scientific Research and Experimental Development (SR&ED) credit, an increase in the limitation of deductibility of interest expense in France, and the movement from an enhanced deduction related to research and development costs to a research and development credit in the U.K. that is recorded in cost of services. In addition, the effective tax rate for the six months ended June 28, 2014 reflects a discrete tax cost of $1,406 related to the nondeductible transaction costs incurred in 2014 for the acquisition of the Early Discovery businesses and a discrete tax cost of $1,220 related to the write-off of deferred tax assets as a result of the reorganization of the Company's RMS U.K. entities. These increases were partially offset by an ability to offset a capital gain from an investment in a limited partnership resulting in a release of an uncertain tax position of $305 and $2,142 in the three and six months ended June 28, 2014, respectively.

During the second quarter of 2014, the Company's unrecognized tax benefits recorded increased by $18,850 to $34,762 primarily due to pre-acquisition tax positions taken by the newly acquired Early Discovery businesses. The amount of unrecognized income tax benefits that would impact the effective tax rate increased by $18,585 to $32,878 primarily due to pre-acquisition tax positions taken by the newly acquired Early Discovery businesses. The amount of accrued interest on unrecognized tax benefits increased by $585 to $1,252 in the second quarter of 2014 primarily due to the pre-acquisition tax positions taken by the newly acquired Early Discovery businesses. The Company believes that it is reasonably possible that the Company's unrecognized tax benefits (and a corresponding indemnification asset), will decrease by up to $12,211, including $511 of interest expense, over the next twelve-month period as a result of the expiration of the statute of limitations on an issue related to the forgiveness of debt.

In July 2013, the FASB issued ASU 2013-11 “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” The ASU requires an entity to present an unrecognized tax benefit as a reduction of the deferred tax asset for a net operating loss, or similar loss or tax credit carryforward, as opposed to a liability, unless certain circumstances exist. The ASU became effective during the Company's first fiscal quarter and the Company adopted the provisions of ASU 2013-11 retrospectively. The adoption of the ASU decreased net non-current deferred tax assets and decreased the associated long-term tax liabilities related to unrecognized tax benefits by $16,271 and $11,865 as of June 28, 2014 and December 28, 2013, respectively.

The Company conducts business in a number of tax jurisdictions. As a result, it is subject to tax audits in jurisdictions including the U.S., U.K., Japan, France, Germany, and Canada. With few exceptions, the Company is no longer subject to U.S. and international income tax examinations for years before 2010 although carryforward attributes that were generated prior to 2010 may still be adjusted upon examination by taxing authorities if they either have been, or will be, used in a future period. As of June 28, 2014, the Company anticipates the statute of limitations to expire within the next twelve months for a year which includes an uncertain tax position associated with an acquisition agreement termination fee. However, the Company does not expect the liability associated with this uncertain tax position to decrease until the statute expires on the year in which a carryforward attribute is utilized.

The Company and certain of its subsidiaries are currently under audit by various tax authorities in the U.S., Canada, Germany, and France. The Company does not believe that resolution of these controversies will have a material impact on its financial position or results of operations.

On June 4, 2014, the Quebec government furthered a proposed tax law change on its SR&ED credit that, if passed, would provide a one-time benefit to operating income in the year of enactment and would provide a corresponding increase to the Company's effective tax rate. If passed as proposed, this tax law change would also provide for a reduction in benefit to operating income in 2015 and an additional corresponding increase to the Company's effective tax rate in 2015 and beyond.

In accordance with the Company's policy, the remaining undistributed earnings of its non-U.S. subsidiaries remain indefinitely reinvested as of the end of the second quarter of 2014 as they are required to fund needs outside the U.S. and cannot be repatriated in a manner that is substantially tax free.

The income tax expense (benefit) related to items of other comprehensive income are as follows:

	Three Months Ended					Six Months Ended

12. STOCK PLANS AND STOCK-BASED COMPENSATION

The Company has stock-based compensation plans under which employees and non-employee directors may be granted stock-based awards such as stock options, restricted stock and performance share units.

The following table provides the financial statement line items in which stock-based compensation is reflected:

Performance Based Stock Award Program

In the first quarters of 2014 and 2013, the Company issued performance share units (PSUs) to certain employees. The number of common stock issued for each PSU is adjusted based on a performance condition linked to the Company's financial performance. Certain awards are further adjusted based on a market condition, which is calculated based on the Company's stock price performance relative to a peer group over the three year vesting period. The fair value of the market condition is reflected in the fair value of the award at grant date. Each reporting period, the Company records a ratable amount of stock-based compensation for the estimated number of common shares expected to be issued upon the vesting of the PSUs based on the Company's estimated outcome for the performance condition.

During the three months ended March 29, 2014, the Company issued 214,823 PSUs using a fair value per share of $67.82. The maximum amount of common shares to be issued upon vesting of these PSUs is 429,646. During the first quarter of 2013, the Company issued 163,847 PSUs using a fair value per share of $44.47. The maximum amount of common shares to be issued upon vesting of these PSUs is 327,694. During the three months ended June 28, 2014, the Company issued 5,800 PSUs using a fair value per share of $61.25. These 5,800 PSUs are not adjusted based on a market condition and have a maximum amount of common shares to be issued upon vesting of 5,800. For the three and six months ended June 28, 2014, the Company recognized $2,620 and $3,654, respectively, of stock-based compensation related to performance share units granted in 2014 and 2013.

13. COMMITMENTS AND CONTINGENCIES

Various lawsuits, claims and proceedings of a nature considered normal to the Company's business are pending against it. In the opinion of management, the outcome of such proceedings and litigation currently pending will not materially affect the Company's consolidated financial statements.

In early May 2013, the Company commenced an investigation into inaccurate billing with respect to certain government contracts.  The Company promptly reported these matters to the relevant government contracting officers, the Department of Health and Human Services' Office of the Inspector General, and the Department of Justice, and the Company is cooperating with these agencies to ensure the proper repayment and resolution of this matter. The Company identified approximately $1,500 in excess amounts billed on these contracts since January 1, 2007 and reserved such amount.  Because of the preliminary stage of discussions with the government and complex nature of this matter, the Company believes that it is reasonably possible that additional losses may be incurred. However, the Company cannot at this time estimate the potential range of loss beyond the current reserve of $1,500. 

In July 2012, a Mauritius supplier of large animal models submitted an Application for Arbitration with The Permanent Secretariat, The Permanent Court of Arbitration, The Mauritius Chamber of Commerce and Industry in Port Louis, Mauritius.  The supplier asserted that the Company failed to pay certain invoices and the supplier was therefore permitted to terminate the

supply agreement.  The Company filed a counterclaim asserting that the supplier had failed to meet its contractual obligations under the supply agreement.  The arbitration hearing relating to this contract dispute took place in Mauritius in August 2013 and final arguments were presented in March 2014. In May 2014 and August 2014, the arbitrator issued the final rulings, ordering the Company to pay the supplier (1) the sum of $1,200 and (2) all of the supplier's arbitration costs, in each case with interest. The Company is awaiting clarification from the arbitrator as to the magnitude of the arbitration costs and the determination of the interest amounts.

A result of the Company's April 1, 2014 Early Discovery acquisition, the Company became the obligor for an aggregate of approximately $72,700 in minimum lease payments under non-cancellable operating and capital leases payable over a period of up to 20 years.

14. BUSINESS SEGMENT INFORMATION

During the quarter ended June 28, 2014, the Company revised its reportable segments to align with its view of the business following its Early Discovery acquisition.

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

The following discussion should be read in conjunction with our condensed consolidated financial statements and accompanying footnotes of this quarterly report on Form 10-Q and our audited consolidated financial statements and related footnotes included in our Annual Report on Form 10-K for the year ended December 28, 2013.

Overview

We are a leading full-service contract research organization (CRO) with integrated early-stage capabilities to support the drug discovery and early-stage development process. We provide our products and services to pharmaceutical and biotechnology companies, government agencies, leading hospitals and academic institutions around the world in order to bring drugs to market faster and more efficiently. We have built upon our core competency of laboratory animal medicine and science (research model technologies) to develop a diverse portfolio of discovery and safety assessment services, both Good Laboratory Practice (GLP) and non-GLP that are able to support our clients from target identification through preclinical development. Utilizing our broad portfolio of products and services enables our clients to create a more flexible drug development model, which reduces their costs, enhances their productivity and effectiveness and increases speed to market. We have been in business for over 65 years and currently operate more than 70 facilities in 17 countries worldwide.

During the quarter ended June 28, 2014, we revised our reportable segments to ensure alignment with our view of the business following our acquisition of the CRO services division of Galapagos N.V. (Early Discovery). We reviewed the new and existing markets addressed by the business, the recently revised go-to-market strategy, long-term operating margins, the discrete financial information available to its Chief Operating Decision Maker and considered how our businesses aggregate based on these qualitative and quantitative factors. Based on this review, we identified three reportable segments: Research Models and Services (RMS), Discovery and Safety Assessment (DSA) and Manufacturing Support (Manufacturing). We will report segment results on this basis beginning in the quarter ended June 28, 2014 and retrospectively for all comparable prior periods. The change to our reportable segment does not impact our historical consolidated operating results previously reported.

The revised reportable segments are as follows:

Research Models and Services	Discovery and Safety Assessment	Manufacturing Support
Research Models	Discovery Services (1)	Endotoxin and Microbial Detection
