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; 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, 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; our cost structure; the impact of acquisitions (including Argenta and BioFocus, VivoPath, ChanTest, Sunrise and Celsis); 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 we plan 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 27, 2014 under the sections entitled “Our Strategy,” “Risk Factors,” “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.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. | BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements are unaudited and have been prepared by Charles River Laboratories International, Inc. (the Company) in accordance with accounting principles generally accepted in the United States (U.S. GAAP) and pursuant to Rule 10-01 of Regulation S-X. The year-end condensed consolidated balance sheet data was derived from the Company’s audited financial statements, but does not include all disclosures required by U.S. GAAP. These interim condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 27, 2014. The condensed consolidated financial statements, in the opinion of management, reflect all normal and recurring adjustments necessary for a fair statement of our financial position and results of operations. Certain reclassifications have been made to prior year amounts to conform to the current year presentation. The Company’s fiscal year is the twelve-month period ending the last Saturday in December.
Use of Estimates
The preparation of condensed consolidated financial statements in accordance with U.S. GAAP requires that the Company make 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, judgments and methodologies. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of 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.
Consolidation
The Company’s consolidated financial statements reflect its financial statements and those of its subsidiaries in which the Company holds a controlling financial interest. 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 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.
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 2014 Annual Report on Form 10-K.
Newly Adopted Accounting Pronouncements
In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-03, “Simplifying the Presentation of Debt Issuance Costs,” which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of debt discounts or premiums. The ASU is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. During the three months ended June 27, 2015, the Company elected early adoption of this standard and applied the changes retrospectively to all prior periods presented in its consolidated financial statements.
The Company historically presented deferred debt issuance costs, or fees related to directly issuing debt, as assets on the consolidated balance sheets. As of June 27, 2015 and December 27, 2014, the adoption of this standard has resulted in the reclassification of $7.7 million and $5.4 million, respectively, from other assets to long-term debt, net and capital leases. These costs will continue to be amortized as interest expense over the term of the corresponding debt issuance.
Newly Issued Accounting Pronouncements
In April 2015, FASB issued ASU 2015-04, “Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets” to provide a practical expedient related to the measurement date of the defined benefit plan assets and obligations. The practical expedient allows employers with fiscal year-end dates that do not coincide with a calendar month end to measure pension and post-retirement benefit plan assets and obligations as of the calendar month-end date closest to the fiscal year end. The standard requires entities that elect the practical expedient to adjust the measurement of benefit plan assets and obligations for contributions or significant events between the month-end measurement date and the entity fiscal year end. The ASU is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. The Company is still evaluating the impact the election of the practical expedient would have on its consolidated financial statements and related disclosures.
In February 2015, the FASB issued ASU 2015-02, “Amendments to the Consolidation Analysis,” which amends existing consolidation requirements. The guidance affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the guidance amends (i) the identification of variable interests (fees paid to a decision maker or service provider), (ii) the variable interest entity characteristics for a limited partnership or similar entity and (iii) the primary beneficiary determination. The ASU is effective for fiscal years beginning after December 15, 2015, and interim periods within
7

those fiscal years. Early adoption is permitted. The adoption of this standard is not expected to have a significant impact on the Company’s financial position or results of operations.
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. The ASU was originally effective for annual and interim periods beginning after December 15, 2016; however, on July 9, 2015, the FASB decided to defer by one year the effective date of the ASU. As a result, the standard will be effective for annual and interim periods beginning after December 15, 2017. 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
Sunrise
On May 5, 2015, the Company acquired Sunrise Farms, Inc. (Sunrise), a producer of specific pathogen free fertile chicken eggs and chickens for the manufacture of live viruses. The purpose of this business acquisition was to expand the capabilities of the Company’s existing Avian Vaccine Services business. The preliminary purchase price of the acquisition was $9.6 million and included payments for estimated working capital, which is subject to final adjustment based on the actual working capital of the acquired business as of the closing date. The acquisition was funded by cash on hand and borrowings on the Company's revolving credit facility. The business is reported in the Company's Manufacturing Support (Manufacturing) reportable segment.
The Company recorded a bargain purchase gain of $9.9 million, which represents the excess of the estimated fair value of the net assets acquired over the preliminary purchase price. The bargain purchase gain was recorded in other income (expense), net in the Company’s consolidated statement of income and was not recognized for tax purposes. The Company believes there were several factors that contributed to this transaction resulting in a bargain purchase gain, including the highly specialized nature of Sunrise’s business falling outside of the seller’s core activities and a limited pool of potential buyers.
Before recognizing the gain from the bargain purchase, the Company reassessed its initial identification and valuation of assets acquired and liabilities assumed to validate that all assets and liabilities that the Company is able to identify at the acquisition date are properly recognized.
The preliminary purchase price allocation of $9.6 million, net of less than $0.1 million of cash acquired, is as follows:

| May 5, 2015
| (in thousands)
Accounts receivable, net | $ | 981 |
Inventory | 1,518 |
Other current assets (excluding cash) | 318 |
Property, plant and equipment | 13,866 |
Definite-lived intangible assets | 3,400 |
Current liabilities | (397 | )
Long-term liabilities | (250 | )
Fair value of net assets acquired | 19,436 |
Bargain purchase gain | (9,878 | )
Total purchase price allocation | $ | 9,558 |

The purchase price allocations were prepared on a preliminary basis and are subject to change as additional information becomes available concerning the fair value and tax basis of the assets acquired and liabilities assumed. Any additional adjustments to the purchase price allocation will be made as soon as practicable but no later than one year from the date of acquisition.

The identifiable definite-lived intangible assets acquired represent the client relationships intangible, which is being amortized over the estimated useful life of approximately 15 years.
The Company incurred transaction and integration costs in connection with the acquisition of $0.3 million and $0.6 million during the three and six months ended June 27, 2015, respectively, which were included in selling, general and administrative expenses.
ChanTest
In October 2014, the Company acquired ChanTest Corporation (ChanTest), a leading provider of ion channel testing services to the pharmaceutical and biotech industry. The acquisition augments the Company’s early discovery capabilities and enhances the Company’s ability to support clients’ target discovery and lead optimization efforts. The preliminary purchase price of the acquisition was $59.3 million, including $0.3 million in contingent consideration. The aggregate, undiscounted amount of contingent consideration that could become payable is a maximum of $2.0 million. The Company estimated the fair value of this contingent consideration based on a probability-weighted set of outcomes. The purchase price is subject to an adjustment based on the final determined net working capital as of the closing date. The business is reported in the Company’s Discovery and Safety Assessment (DSA) reportable segment.
The preliminary purchase price allocation of $52.1 million, net of $7.2 million in cash acquired, is as follows:

| October 29, 2014
| (in thousands)
Current assets (excluding cash) | $ | 4,648 |
Property, plant and equipment | 1,579 |
Definite-lived intangible assets | 23,920 |
Goodwill | 34,927 |
Current liabilities | (3,515 | )
Long-term liabilities | (9,486 | )
Total purchase price allocation | $ | 52,073 |

The purchase price allocations were prepared on a preliminary basis and are subject to change as additional information becomes available concerning the fair value and tax basis of the assets acquired and liabilities assumed. During the six months ended June 27, 2015, the Company recorded measurement period adjustments related to the ChanTest acquisition that resulted in an immaterial change to the purchase price allocation. Any additional adjustments to the purchase price allocation will be made as soon as practicable but no later than one year from the date of acquisition.
The breakout of definite-lived intangible assets acquired is as follows:

Other intangible assets | 4,920 |  |  | 9
Total definite-lived intangible assets | $ | 23,920 |  |  |

The definite-lived intangibles are largely attributed to the expected cash flows related to client relationships existing at the acquisition closing date. The goodwill resulting from the transaction is primarily attributed to the potential growth of the business and is not deductible for tax purposes.
VivoPath
In June 2014, the Company acquired substantially all of the assets of VivoPath LLC (VivoPath), a discovery services company specializing in the rapid, in vivo compound evaluation of molecules in the therapeutic areas of metabolism, inflammation and oncology. The purchase price was $2.3 million, including $1.6 million in contingent consideration, and was allocated primarily to the intangible assets acquired. The aggregate, undiscounted amount of contingent consideration that could become payable is a maximum of $2.4 million, payable over three years based on the achievement of revenue growth targets. During the three

months ended June 27, 2015, the first-year tranche of the contingent consideration of $0.6 million was earned. The Company estimated the fair value of this contingent consideration based on a probability-weighted set of outcomes. The business is reported in the Company’s DSA reportable segment.
Argenta and BioFocus
On April 1, 2014, the Company acquired (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 contract research organization, with integrated in vitro and in vivo capabilities from target discovery through preclinical development. The purchase price of the acquisition was $191.8 million, including $0.9 million in contingent consideration. The acquisition was funded by cash on hand and borrowings on the Company’s revolving credit facility. The purchase price included payment for estimated working capital, which was subject to final adjustment based on the actual working capital of the acquired business. The businesses are reported in the Company’s DSA reportable segment.
The contingent consideration earn-out period ended on April 1, 2015. As a result, the related contingent consideration liability, as adjusted for subsequent changes in fair value, was reversed and a gain of $0.8 million was recorded in selling, general, and administrative expenses during the three months ended March 28, 2015, as no payments are expected to be made. The contingent consideration was a one-time payment that could have become payable in the second quarter of 2015 based on the achievement of a certain revenue target for the twelve-month period following the acquisition. The aggregate, undiscounted amount of contingent consideration that the Company could have paid was €5.0 million ($5.6 million as of June 27, 2015). The Company estimated the fair value of this contingent consideration based on a probability-weighted set of outcomes.
The purchase price allocation of $183.6 million, net of $8.2 million of cash acquired, was as follows (in thousands):

Current assets (excluding cash) | $ | 31,682 |
Property, plant and equipment | 21,008 |
Other long term assets | 11,140 |
Definite-lived intangible assets | 104,470 |
Goodwill | 65,235 |
Current liabilities | (13,139 | )

The goodwill resulting from the transaction is primarily attributed to the potential growth of the Company’s DSA businesses from clients introduced through Argenta and BioFocus, 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 less than $0.1 million during the three and six months ended June 27, 2015 and of $1.6 million and $4.9 million during the three and six months ended June 28, 2014, respectively, which were included in selling, general and administrative expenses.

There were no sales of available-for-sale securities during the six months ended June 27, 2015.
6. FAIR VALUE
The Company has certain financial assets and liabilities recorded at fair value which have been classified as Level 1, 2, or 3 within the fair value hierarchy:

• | Level 1 - Fair values are determined utilizing quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access;

• | Level 2 - Fair values are determined by utilizing quoted prices for identical or similar assets and liabilities in active markets or other market observable inputs such as interest rates, yield curves, and foreign currency spot rates;

• | Level 3 - Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

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. The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each quarter. During the six months ended June 27, 2015 and June 28, 2014, there were no transfers between levels.
14

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Valuation methodologies used for assets and liabilities measured or disclosed at fair value are as follows:

• | Cash equivalents - Valued at quoted market prices determined through third-party pricing services.

• | Mutual funds - Valued at the unadjusted quoted net asset value of shares held by the Company.

• | 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.

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

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

Redeemable Noncontrolling Interest
The Company’s redeemable noncontrolling interest resulted from the acquisition of a 75% ownership interest in Vital River. Concurrent with the acquisition, the Company entered into a joint venture agreement with the noncontrolling interest holders that provides the Company 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 purchase the remaining 25%

interest, the noncontrolling interest is classified in the mezzanine section of the consolidated balance sheet, which is above the equity section and below liabilities.
The following table provides a rollforward of the fair value of the Company’s redeemable noncontrolling interest:

| Six Months Ended
| June 27, 2015 |  | June 28, 2014
| (in thousands)
Beginning balance | $ | 28,419 |  |  | $ | 20,581 |

Total gains or losses (realized/unrealized): |  |  |
Net income attributable to noncontrolling interest | 364 |  |  | 372 |
Foreign currency translation | 112 |  |  | (462 | )
Change in fair value, included in additional paid-in capital | 1,081 |  |  | 2,992 |
Ending balance | $ | 29,976 |  |  | $ | 23,483 |

The significant unobservable inputs used in the fair value measurement of the Company’s redeemable noncontrolling interest are the estimated future cash flows based on projected financial data and a discount rate of 19.0%. Significant changes in the timing or amounts of the estimated future cash flows would result in a significantly higher or lower fair value measurement. Significant increases or decreases in the discount rate would result in a significantly lower or higher fair value measurement, respectively.
Contingent Consideration
The following table provides a rollforward of the contingent consideration related to the acquisitions of Argenta, BioFocus, VivoPath and ChanTest. See Note 2, “Business Acquisitions.”

| Six Months Ended

Reversal of previously recorded contingent liability and change in fair value | (672 | ) |  | (8 | )
Ending balance | $ | 2,831 |  |  | $ | 2,420 |

The significant unobservable inputs used in the fair value measurement of the Company’s contingent consideration are the probabilities of successful achievement of certain financial 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.
Debt Instruments
The book value of the Company’s term and revolving loans, which are variable rate loans carried at amortized cost, approximates their 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.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)
In April 2015, the Company amended and restated the $970M Credit Facility creating a $1.3 billion facility ($1.3B Credit Facility) that provides for a $400.0 million term loan facility and $900.0 million multi-currency revolving facility. The term loan facility matures in 20 quarterly installments with the last installment due April 22, 2020. The revolving facility matures on April 22, 2020 and requires no scheduled payment before that date.
The interest rates applicable to term loans and revolving loans under our credit agreement are, at our option, equal to either the base rate (which is the higher of (1) the prime rate, (2) the federal funds rate plus 0.5% or (3) the one-month adjusted LIBOR rate) or the adjusted LIBOR rate plus an interest rate margin based upon the our leverage ratio. As of June 27, 2015 and December 27, 2014, the weighted average interest rate on the Company’s debt was 1.31% and 1.42%, respectively.
The $1.3B Credit Facility includes certain customary representations and warranties, events of default, notices of material adverse changes to the Company’s business, and negative and affirmative covenants. As of June 27, 2015, the Company was compliant with all covenants.
At June 27, 2015 and December 27, 2014, the Company had $4.9 million and $5.0 million in outstanding letters of credit, respectively.
Capital Lease Obligations
The Company acquired a built-to-suit lease as part of its acquisition of Argenta and BioFocus. In accordance with accounting guidance applicable to entities involved with the construction of an asset that will be leased when the construction is completed, the Company was considered the owner, for accounting purposes, of this property during the construction period. Accordingly, the Company recorded an asset and a corresponding financing obligation on its consolidated balance sheet for the amount of total project costs incurred related to the construction in progress for this property through completion of the construction period. Upon completion of the construction, the Company determined that it is no longer considered the owner of the property because it did not have continuing involvement. Consequently, the Company recorded a successful sale leaseback and derecognized the property and the associated financing obligation from the Company’s consolidated balance sheet and recorded a capital lease asset and a corresponding liability of $35.8 million.
The Company’s capital lease obligations amounted to $37.4 million and $1.0 million at June 27, 2015 and December 27, 2014, respectively.

excluded the weighted average impact of approximately 1.1 million and 1.2 million shares, respectively, of non-vested restricted stock and restricted stock units.
Treasury Shares
In July 2010, the Company’s Board of Directors authorized a $500.0 million stock repurchase program, and subsequently approved increases to the stock repurchase program of $250.0 million in 2010, $250.0 million in 2013 and $150.0 million in 2014 for an aggregate authorization of $1,150.0 million. The Company repurchased approximately 1.2 million shares for $90.8 million and approximately 1.7 million shares for $90.3 million in the six months ended June 27, 2015 and June 28, 2014, respectively. As of June 27, 2015, the Company had $87.6 million remaining on the authorized stock repurchase program. The Company’s 2007 Incentive Plan permits the netting of common stock upon vesting of restricted stock and restricted stock units in order to satisfy individual minimum statutory tax withholding requirements. During the six months ended June 27, 2015 and June 28, 2014, the Company acquired approximately 0.1 million shares for $8.7 million and approximately 0.1 million shares for $6.7 million, respectively.
Accumulated Other Comprehensive Income (Loss)

June 27, 2015 | $ | (37,017 | ) |  | $ | (53,346 | ) |  | $ | (90,363 | )

Foreign currency translation and other includes an insignificant amount of unrealized gains (losses) on available-for-sale marketable securities.
Nonredeemable Noncontrolling Interests
The Company has investments in several entities, whose financial results are consolidated in the Company’s financial statements, as it has the ability to exercise control over these entities. The interests of the respective noncontrolling parties in these entities have been recorded as noncontrolling interests. The activity within the nonredeemable noncontrolling interests was insignificant during the three and six months ended June 27, 2015 and June 28, 2014.
10. INCOME TAXES
The Company’s overall effective tax rate for the three months ended June 27, 2015 and June 28, 2014 was 18.4% and 27.9%, respectively. The Company’s overall effective tax rate was 12.4% and 26.1% for each of the six months ended June 27, 2015 and June 28, 2014, respectively. For the three months ended June 27, 2015 the decrease was primarily attributable to a $1.8 million release of an uncertain tax position resulting from an ability to offset tax on a capital gain from an investment in a limited partnership, the non-taxable bargain purchase gain of $9.9 million associated with the acquisition of Sunrise, and a prior year discrete tax cost of $1.4 million related to nondeductible transaction costs. For the six months ended June 27, 2015, the decrease reflects the items above as well as a reduction in unrecognized tax benefits and related interest of $10.4 million due to the expiration of the statute of limitations associated with pre-acquisition tax positions on forgiveness of debt.
During the three months ended June 27, 2015, the Company’s unrecognized tax benefits decreased by $0.1 million to $23.0 million primarily due to the $1.8 million release resulting from an ability to offset tax on a capital gain from an investment in a limited partnership, offset by the current year reserve associated with Canadian research credits and unfavorable foreign exchange movement. The amount of unrecognized income tax benefits that would impact the effective tax rate decreased by $0.4 million, to $20.1 million. The amount of accrued interest on unrecognized tax benefits was $1.0 million at June 27, 2015.
19

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)
The Company believes that it is reasonably possible that the unrecognized tax benefits will decrease by up to $0.2 million over the next twelve-month period, as a result of the settlement of audits.
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 2011.
The Company and certain of its subsidiaries are currently under audit by various tax authorities in the U.S., Canada, 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 December 2, 2014, the Quebec government released Information Bulletin 2014-11, which elaborated on a proposed law change to its SR&ED credit that, if passed, would provide a one-time retroactive benefit to operating income in the year of enactment and would provide a corresponding increase to the Company’s effective income tax rate. If passed as proposed, the tax law change would also provide an ongoing reduction in benefit to operating income and an additional corresponding increase to the Company’s effective income tax rate in the year of enactment 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 three months ended June 27, 2015 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
| June 27, 2015 |  | June 28, 2014 |  | June 27, 2015 |  | June 28, 2014

During the six months ended June 27, 2015, the Company issued approximately 0.2 million restricted stock units with a per share weighted average grant date fair value of $76.67, less than 0.1 million shares of restricted stock with a per share weighted average grant date fair value of $70.29, approximately 0.5 million stock options with a per share weighted average grant date fair value of $17.27, and approximately 0.2 million PSUs with a per share weighted average grant date fair value of $87.50. The maximum number of common shares to be issued upon vesting of PSUs granted during the six months ended June 27, 2015 is approximately 0.3 million.
During the three months ended March 28, 2015, the Company modified certain stock-based awards granted in previous years as part of executive retirement transitions. For the stock-based awards granted to employees during the six months ended June 27, 2015 the Company introduced a new retirement provision, which allows for continued vesting of such awards after the employee’s retirement if certain eligibility conditions are met. The introduction of the new retirement provision and stock-based award modifications increased the Company’s stock-based compensation expense for the six months ended June 27, 2015 by $2.6 million.

13. COMMITMENTS AND CONTINGENCIES
Litigation
Various lawsuits, claims, and proceedings of a nature considered normal to its business are pending against the Company. While the outcome of any of these proceedings cannot be accurately predicted, the Company does not believe the ultimate resolution of any of these existing matters would have a material adverse effect on the Company’s business or financial condition.
In 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 $1.5 million of excess amounts billed on these contracts since January 1, 2007 and reserved such amount. Because of the ongoing 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 $1.5 million.
Lease Commitments
During the six months ended June 27, 2015, the Company entered into new lease agreements or exercised options to extend the lease terms for certain existing leases. As a result, the Company’s lease obligations through May 2020 increased by $10.1 million.

15. SUBSEQUENT EVENTS
On July 24, 2015, the Company acquired Celsis International Ltd. (Celsis), a leading provider of rapid testing systems for non-sterile bacterial contamination for the biopharmaceutical and consumer products industries. The purpose of this acquisition was to expand the portfolio of the Company’s Endotoxin and Microbial Detection (EMD) business. The preliminary purchase price for Celsis was $212.0 million in cash, which is subject to a final net working capital adjustment as of the closing date. The business will be reported in the Company’s Manufacturing reportable segment. Due to the limited time between the acquisition date and the filing of this Quarterly Report on Form 10-Q, it is not practicable for the Company to disclose the preliminary allocation of purchase price to assets acquired and liabilities assumed.

Overview
We are a full service, early-stage contract research organization. For nearly 70 years, we have been in the business of providing the research models required in research and development of new drugs, devices, and therapies. Over this time, we have built upon our original core competency 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. We also provide a suite of products and services to support our clients’ manufacturing activities. 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 currently operate approximately 62 facilities in 17 countries worldwide, which numbers exclude our Insourcing Solutions (IS) sites.
We report our financial performance in three segments: Research Models and Services (RMS), Discovery and Safety Assessment (DSA) and Manufacturing Support (Manufacturing). Our RMS segment includes the Research Models and Research Model Services businesses. Research Models includes the commercial production and sale of small research models, as well as the supply of large research models. Research Model Services includes three business units: Genetically Engineered Model Services, which performs contract breeding and other services associated with genetically engineered models; Research Animal Diagnostic Services, which provides health monitoring and diagnostics services related to research models; and IS, which provides colony management of our clients’ research operations (including recruitment, training, staffing and management services). Our DSA segment includes services required to take a drug through the early development process including discovery services, which are non-regulated services to assist clients with the identification, screening and selection of a lead compound for drug development, and regulated and non-regulated safety assessment services. Our Manufacturing segment includes Endotoxin and Microbial Detection (EMD), which includes in vitro (non-animal) lot-release testing products and microbial detection and species identification services, as well as Biologics Testing Services (Biologics), which performs specialized testing of biologics and devices, and Avian Vaccine Services (Avian), which supplies specific-pathogen-free fertile chicken eggs and chickens.

Revenue for the three months ended June 27, 2015 decreased $1.6 million, or 0.5%, compared with the corresponding period in 2014. Reported revenue decreased by $20.9 million, or 6.2%, when compared to the prior period, due to negative effects of changes in foreign currency exchange rates.
RMS revenue decreased by $13.1 million primarily due to lower research models revenue in Europe and Japan and lower research model services revenue, partially offset by an increase of research models revenue in North America.
DSA revenue increased $10.8 million due to higher revenue in the Safety Assessment business, with study volume, market share gains, and pricing as the primary contributors, as well as an increase in the Discovery Services business, which includes the ChanTest acquisition.
25

Manufacturing revenue increased $0.7 million, as higher Avian revenue, which includes the Sunrise acquisition, was offset by lower Biologics revenue.

The increase was due primarily to the write-off of a portion of debt issuance costs in connection with the modification of our $970M Credit Facility and interest expense related to new capital leases.
Other Income (Expense), Net Other income (expense), net was a net other income of $8.7 million for the three months ended June 27, 2015, an increase of $6.0 million, or 225.2%, compared to a net other income of $2.7 million for the three months ended June 28, 2014. The increase in other income (expense), net was due mainly to a $9.9 million gain on the bargain purchase of Sunrise, partially offset by a decrease of $3.0 million in income from our investments in limited partnerships accounted for under the equity method and other activity of $0.9 million.
Income Taxes Income tax expense for the three months ended June 27, 2015 was $11.1 million, a decrease of $3.0 million compared to $14.1 million for the three months ended June 28, 2014. Our effective tax rate was 18.4% for the second quarter of 2015, compared to 27.9% for the second quarter of 2014. The decrease was primarily attributable to a $1.8 million release of an uncertain tax position resulting from an ability to offset tax on a capital gain from an investment in a limited partnership, the non-taxable bargain purchase gain of $9.9 million associated with the acquisition of Sunrise, and a prior year discrete tax cost of $1.4 million related to nondeductible transaction costs.

Liquidity and Capital Resources
We currently require cash to fund our working capital needs, pension obligations, capital expansion, and acquisitions and pay our debt obligations. Our principal sources of liquidity have been our cash flows from operations, supplemented by long-term borrowings. Based on our current business plan, we believe that our existing funds, when combined with cash generated from operations and our access to financing resources, are sufficient to fund our operations for the foreseeable future.

Borrowings
In April, 2015, we amended and restated our $970M Credit Facility creating a $1.3 billion facility ($1.3B Credit Facility) that provides for a $400.0 million term loan facility and $900.0 million multi-currency revolving facility. The term loan facility matures in 20 quarterly installments with the last installment due April 22, 2020. The revolving facility matures on April 22, 2020 and requires no scheduled payment before that date. The interest rates applicable to term loans and revolving loans under our credit agreement are, at our option, equal to either the base rate (which is the higher of (1) the prime rate, (2) the federal funds rate plus 0.50% or (3) the one-month adjusted LIBOR rate) or the adjusted LIBOR rate plus an interest rate margin based upon the our leverage ratio.
Amounts outstanding under the $1.3B Credit Facility were as follows:

Operating cash flow is derived by adjusting our net income from continuing operations for (1) non-cash operating items such as depreciation and amortization, stock-based compensation and gains (losses) on investments in limited partnerships and gains on bargain purchases as well as (2) changes in operating assets and liabilities, which reflect timing differences between the receipt and payment of cash associated with transactions and when they are recognized in our results of operations. For the six months ended June 27, 2015, compared to the six months ended June 28, 2014, the increase in cash provided by operating activities is primarily driven by higher income from continuing operations. Our days sales outstanding, which includes deferred revenue as an offset to accounts receivable in the calculation, was 54 days as of June 27, 2015, compared to 52 days as of December 27, 2014.

For the six months ended June 27, 2015, cash used by financing activities reflected treasury stock purchases of $99.5 million made primarily pursuant to our authorized stock repurchase program and net debt repayments of $7.1 million, partially offset by proceeds from exercises of employee stock options of $35.6 million . For the six months ended June 28, 2014, cash provided by financing activities reflected net debt borrowings of $139.5 million and proceeds from exercises of employee stock options of $36.5 million, partially offset by treasury stock purchases of $101.6 million.
Contractual Commitments and Obligations
The disclosure of our contractual obligations and commitments was reported in our Annual Report on Form 10-K for the year ended December 27, 2014. There have been no material changes from the contractual commitments and obligations previously disclosed in our Annual Report on Form 10-K other than the changes described in Note 13, “Commitments and Contingencies,” in this Quarterly Report on Form 10-Q.
Off-Balance Sheet Arrangements
We do not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, that would have been established for the purpose of facilitating off-balance sheet arrangements (as that term is defined in Item 303(a)(4)(ii) of Regulation S-K) or other contractually narrow or limited purposes. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in those types of relationships. We include standard indemnification provisions in client contracts, which include standard provisions limiting our liability under such contracts, including our indemnification obligations, with certain exceptions.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States (U.S.). The preparation of these financial statements requires us to make certain estimates and assumptions that may affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses during the reported periods and related disclosures. These estimates and assumptions are monitored and analyzed by us for changes in facts and circumstances, and material changes in these estimates could occur in the future. We base our estimates on our historical experience, trends in the industry, and various other factors that are believed to be reasonable under the circumstances. Actual results may differ from our estimates under different assumptions or conditions.
31

We believe that our application of the following accounting policies, each of which require significant judgments and estimates on the part of management, is the most critical to aid in fully understanding and evaluating our reported financial results: (1) revenue recognition, (2) income taxes, (3) goodwill and intangible assets, (4) valuation and impairment of long-lived assets, (5) pension and other retiree benefit plans, and (6) stock-based compensation. Our critical accounting policies are described in our Annual Report on Form 10-K for the fiscal year ended December 27, 2014.
Recent Accounting Pronouncements
For a discussion of recent accounting pronouncements please refer to Note 1, “Basis of Presentation,” in this Quarterly Report on Form 10-Q. We did not adopt any new accounting pronouncements during the six months ended June 27, 2015 that had a material effect on our condensed consolidated financial statements included in this report.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
We are exposed to market risk from changes in interest rates and currency exchange rates, which could affect our future results of operations and financial condition. We manage our exposure to these risks through our regular operating and financing activities.
Interest Rate Risk
We are exposed to changes in interest rates while conducting normal business operations as a result of ongoing financing activities. As of June 27, 2015, our debt portfolio was comprised primarily of floating interest rate borrowings. A 100-basis point increase in interest rates would increase our annual pre-tax interest expense by approximately $13.0 million.
Foreign Currency Exchange Rate Risk
We operate on a global basis and have exposure to some foreign currency exchange rate fluctuations for our financial position, results of operations and cash flows.
While the financial results of our global activities are reported in U.S. dollars, our foreign subsidiaries typically conduct their operations in their respective local currency. Fluctuations in the foreign currency exchange rates of the countries in which we do business will affect our operating results, often in ways that are difficult to predict. In particular, as the U.S. dollar strengthens against other currencies the value of our non-U.S. revenue will decline when reported in U.S. dollars. The impact to net income as a result of a U.S. dollar strengthening will be partially mitigated by the value of non-U.S. expense which will also decline when reported in U.S. dollars. As the U.S. dollar weakens versus other currencies the value of the non-U.S. revenue and expenses will increase when reported in U.S. dollars.
We attempt to minimize this exposure by using certain financial instruments in accordance with our overall risk management and our hedge policy. We do not enter into speculative derivative agreements.
During the six months ended June 27, 2015, we utilized foreign exchange contracts, principally to hedge certain balance sheet exposures resulting from currency fluctuations. No foreign currency contracts were open at June 27, 2015.

Item 4. Controls and Procedures
(a) Evaluation of Disclosure Controls and Procedures
Based on their evaluation, required by paragraph (b) of Rules 13a-15 or 15d-15, promulgated by the Securities Exchange Act of 1934, as amended (Exchange Act), the Company’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act, are effective, at a reasonable assurance level to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, as of June 27, 2015. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurances of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures. We continually are in the process of further reviewing and documenting our disclosure controls and procedures, and our internal control over financial reporting, and accordingly may, from time to time, make changes aimed at enhancing their effectiveness to ensure that our systems evolve with our business.
(b) Changes in Internal Controls
There were no changes in the Company’s internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of the Exchange Act Rules 13a-15 or 15d-15 that occurred during the quarter ended June 27, 2015 that materially affected, or were reasonably likely to materially affect, the Company’s internal control over financial reporting.
