CHARLES RIVER LABORATORIES INTERNATIONAL, INC. - Annual Report: 2023 (Form 10-K)

Interest expense for fiscal year 2023 was $136.7 million, an increase of $77.4 million, or 130.6%, compared to $59.3 million in fiscal year 2022. The increase was due primarily to higher interest rates, and the absence of $49.7 million of gains recognized in connection with a debt-related foreign exchange forward contract in the corresponding period in 2022.
Other income, net for fiscal year 2023 was $95.5 million, an increase of $65.0 million, or 213.0%, compared to $30.5 million for fiscal year 2022. The increase was due primarily to a gain on acquisition of $98.5 million for Noveprim, the absence of $46.5 million of foreign currency losses recognized in connection with a U.S. dollar denominated loan borrowed by a non-U.S. entity with a different functional currency, and lower net losses incurred on our venture capital, other strategic equity investments, and life insurance investments as compared to fiscal year 2022; partially offset by the absence of a gain on the divestiture of our Avian business of $123.4 million in fiscal year 2022.

Income tax expense for fiscal year 2023 was $100.9 million, a decrease of $29.5 million compared to $130.4 million for fiscal year 2022. Our effective tax rate was 17.4% for fiscal year 2023 compared to 20.9% for fiscal year 2022. The decrease in our effective tax rate in fiscal year 2023 compared to fiscal year 2022 was primarily attributable to the impact of the non-taxable gain on Noveprim of $98.5 million; partially offset by a decreased tax benefit from stock-based compensation deductions.
Liquidity and Capital Resources
Liquidity and Cash Flows
We currently require cash to fund our working capital needs, capital expansion, acquisitions, and to pay our debt, lease, venture capital and strategic equity investments, and pension obligations. Our principal sources of liquidity have been our cash flows from operations, recent divestitures, 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.
The following table presents our cash, cash equivalents and short-term investments:

Net cash provided by operating activities$683,898 $619,640 
Net cash provided by cash flows from operating activities represents the cash receipts and disbursements related to all of our activities other than investing and financing activities. Operating cash flow is derived by adjusting our net income for (1) non-cash operating items such as depreciation and amortization, stock-based compensation, loss on debt extinguishment and other financing costs, deferred income taxes, long-lived asset impairment changes, gains and/or losses on venture capital and strategic equity investments, gains and/or losses on divestitures, changes in fair value of contingent consideration, 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. During fiscal year 2023, our cash flows from operations was $683.9 million compared with $619.6 million for fiscal year 2022. The increase in net cash provided by operating activities was primarily driven by the amounts and timing of compensation payments and inventory purchases.

Net cash used in financing activities$(85,521)$(42,397)
For fiscal year 2023, net cash used in financing activities was primarily driven by debt repayments on our Credit Facility offset by borrowings to fund the recent acquisition of Noveprim.
Net cash used in financing activities also reflected treasury stock purchases of $24.2 million made due to the netting of common stock upon vesting of stock-based awards in order to satisfy individual statutory tax withholding requirements, $4.8 million payment to purchase the remaining 8% interest in our Vital River subsidiary, $4.0 million of dividends paid to noncontrolling interests, and $2.7 million of contingent consideration payments; partially offset by proceeds from exercises of employee stock options of $25.6 million. We did not pay any dividends on our Common Stock in fiscal year 2023 and have no current plans to do so in the coming fiscal year.
For fiscal year 2022, net cash used in financing activities reflected the net proceeds of $19.8 million on our Credit Facility and finance lease obligations. Included in the net proceeds are the following amounts:
Borrowings under our Credit Facility of $300 million, which were used primarily for the acquisition of Explora BioLabs;
Net repayments of $100 million on our Credit Facility throughout fiscal year 2022;
Payments of $2.0 billion partially offset by $1.9 billion of proceeds in connection with a non-U.S. Euro functional currency entity repaying Euro loans and replacing the Euro loans with U.S. dollar denominated loans. A series of forward currency contracts were executed to mitigate any foreign currency gains or losses on the U.S. dollar denominated loans. These proceeds and payments are presented as gross financing activities.
Net cash used in financing activities also reflected treasury stock purchases of $38.7 million made due to the netting of common stock upon vesting of stock-based awards in order to satisfy individual statutory tax withholding requirements, approximately $15 million payment to purchase an additional 10% interest in a subsidiary, $15.7 million payment to acquire the remaining 2% ownership interest in Cognate, $10.4 million of contingent consideration payments, and $5.3 million of dividends paid to noncontrolling interests; partially offset by proceeds from exercises of employee stock options of $25.1 million.

Financing and 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.
Amounts outstanding under our Credit Facility and our Senior Notes were as follows:
December 30, 2023December 31, 2022
(in thousands)
Revolving facility$1,129,243 $1,197,586

4.0% Senior Notes due 2031500,000 500,000 
Total$2,629,243 $2,697,586 
The interest rates applicable to the Credit Facility are equal to (A) for revolving loans denominated in U.S. dollars, at the Company’s option, 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 SOFR rate plus 1.0%) or the adjusted SOFR rate, (B) for revolving loans denominated in euros, the adjusted EURIBOR rate and (C) for revolving loans denominated in sterling, the daily simple SONIA rate, in each case, plus an interest rate margin based upon the Company’s leverage ratio. In March 2023 and in conjunction with the Credit Agreement second amendment (Second Amendment) the Company modified the variable rate on the Credit Facility from adjusted LIBOR to adjusted term SOFR. All outstanding U.S. dollar borrowings remained at adjusted LIBOR through their respective interest reset periods in April 2023 and were then set to term SOFR.
Our 2028 Senior Notes have semi annual interest payments due May 1 and November 1. Our 2029 and 2031 Senior Notes have semi annual interest payments due March 15 and September 15.
During the fourth fiscal quarter of 2022, we entered into an interest rate swap with a notional amount of $500 million to manage interest rate fluctuation related to our floating rate borrowings under the Credit Facility, at a fixed rate of 4.70%. In March 2023 and in conjunction with the Second Amendment, we modified the variable rate on our interest rate swap from 1-month LIBOR to 1-month term SOFR. Effective with the modification we will pay a fixed rate of 4.65% on our swap maturing November 2, 2024. The transition did not have an impact on our hedge accounting or a material impact to our consolidated financial statements.
Our off-balance sheet commitments related to our outstanding letters of credit as of December 30, 2023 were $21.6 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. The principal functional currencies of our foreign subsidiaries are the Euro, British Pound, and Canadian Dollar. During fiscal year 2023, the most significant drivers of foreign currency translation adjustment we recorded as part of other comprehensive income (loss) were the British Pound, Euro, Canadian Dollar, and Hungarian Forint.
Fluctuations in the foreign currency exchange rates of the countries in which we do business will affect our financial position, results of operations, and cash flows. As the U.S. dollar strengthens against other currencies, the value of our non-U.S. revenue, expenses, assets, liabilities, and cash flows will generally 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. expenses, which will decline when reported in U.S. dollars. As the U.S. dollar weakens versus other currencies, the value of the non-U.S. revenue, expenses, assets, liabilities, and cash flows will generally increase when reported in U.S. dollars. For fiscal year 2023, our revenue would have decreased by $126.7 million and our operating income would have decreased by $2.8 million, if the U.S. dollar exchange rate had strengthened by 10%, with all other variables held constant.
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.
We entered into foreign exchange forward contracts during fiscal year December 31, 2022 to limit our foreign currency exposure related to a U.S. dollar denominated loan borrowed by a non-U.S. Euro functional currency entity under the Credit Facility. Refer to Note 11. Debt and Other Financing Arrangements to our consolidated financial statements contained in Item

8, “Financial Statements and Supplementary Data,” in this Annual Report on Form 10-K for further details regarding these types of forward contracts.
Repurchases of Common Stock
During fiscal year 2023, we did not repurchase any shares under our authorized $1.3 billion stock repurchase program. As of December 30, 2023, we had $129.1 million remaining on the authorized stock repurchase program. Our stock-based compensation plans permit the netting of common stock upon vesting of restricted stock, restricted stock units, and performance share units in order to satisfy individual statutory tax withholding requirements. During fiscal year 2023, we acquired 0.1 million shares for $24.2 million through such netting.
Commitments and Other Purchasing Arrangements
We lease properties and equipment for use in our operations. In addition to rent, the leases may require us to pay additional amounts for taxes, insurance, maintenance, and other operating expenses. As of December 30, 2023, we had $757.4 million of operating leases inclusive of future minimum rental commitments under non-cancellable operating leases, net of income from subleases as well as $39.9 million of financing leases. The expected payments of our operating and finance lease liabilities over the next twelve months are $70.6 million and $3.8 million, respectively as of December 30, 2023.
In addition to the obligations on the balance sheet at December 30, 2023, we entered into unconditional purchase obligations in the ordinary course of business. Unconditional purchase obligations include agreements to purchase goods or services that are enforceable and legally binding and that specify all significant terms, including fixed or minimum quantities to be purchased, fixed, minimum or variable price provisions, and the approximate timing of the transaction. Purchase obligations exclude agreements that are cancellable at any time without penalty. As of December 30, 2023, we had approximately $390 million of unconditional purchase obligations, the majority of which are expected to be settled during 2024.
We invest in several venture capital funds that invest in start-up companies, primarily in the life sciences industry. Our total commitment to the funds as of December 30, 2023 was $212.9 million, of which we funded $145.2 million through December 30, 2023.
Refer to Note 8. Venture Capital and Strategic Equity Investments to our consolidated financial statements contained in Item 8, “Financial Statements and Supplementary Data,” in this Annual Report on Form 10-K for further details.
In connection with certain business and asset acquisitions, we agreed to make additional payments based upon the achievement of certain financial targets and other milestones in connection with the respective acquisition. As of December 30, 2023, we had approximately $98 million of gross contingent payments, of which $33 million are expected to be paid.
We have certain federal and state income tax liabilities of $32.4 million relating to the one-time Transition Tax on unrepatriated earnings under the 2017 Tax Act. The Transition Tax will be paid, interest free, over an eight-year period through 2026.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders of Charles River Laboratories International, Inc.:
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Charles River Laboratories International, Inc. and its subsidiaries (the “Company”) as of December 30, 2023 and December 31, 2022, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 30, 2023, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 30, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 30, 2023 and December 31, 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 30, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 30, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
As described in Management’s Report on Internal Control Over Financial Reporting, management has excluded Noveprim Group (“Noveprim”) from its assessment of internal control over financial reporting as of December 30, 2023, because it was acquired by the Company in a purchase business combination during 2023. We have also excluded Noveprim from our audit of internal control over financial reporting. Noveprim is a subsidiary whose total assets and total revenues excluded from management’s assessment and our audit of internal control over financial reporting represent less than 1%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 30, 2023.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over
55

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Acquisition of Noveprim – Valuation of Biological Assets
As described in Notes 1 and 2 to the consolidated financial statements, on November 30, 2023, the Company completed the acquisition of Noveprim, resulting in a 90% controlling interest. Of the acquired long-term assets, $167.8 million of biological assets were recorded. The determination of the fair value of biological assets requires the use of significant judgment using management’s best estimates of inputs and assumptions that a market participant would use. To determine the fair value, management utilized the multiple period excess earnings model, which relies on the following key assumptions: projections of cash flows from the acquired entities, which includes future revenue, cost of revenue, operating income margins, and productivity rates, as well as the discount rate based on market participant’s weighted average cost of capital.
The principal considerations for our determination that performing procedures relating to the valuation of biological assets acquired in the acquisition of Noveprim is a critical audit matter are (i) the significant judgment by management when developing the fair value estimate of the biological assets acquired; (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating management’s significant assumptions related to the cost of revenue, productivity rates, and discount rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the acquisition accounting, including controls over management’s valuation of the biological assets acquired. These procedures also included, among others (i) reading the purchase agreement; (ii) testing management’s process for developing the fair value estimate of the biological assets acquired; (iii) evaluating the appropriateness of the multiple period excess earnings model; (iv) testing the completeness and accuracy of the underlying data used in the multiple period excess earnings model; and (v) evaluating the reasonableness of the significant assumptions used by management related to the cost of revenue, productivity rates, and discount rate. Evaluating management’s assumptions related to the cost of revenue and productivity rates involved considering (i) the past performance of Noveprim; (ii) the consistency with external research data; and (iii) whether the assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in evaluating (i) the appropriateness of the multiple period excess earnings model and (ii) the reasonableness of the discount rate assumption.
Discovery and Safety Assessment Service Revenue Recognized Over Time Using the Input Method
As described in Notes 1 and 3 to the consolidated financial statements, the Company recognized Discovery and Safety Assessment (DSA) revenue from services and products transferred over time of $2,611.6 million for the year-ended December 30, 2023, of which the majority relates to services that are delivered to the customer based on the extent of progress towards completion of the performance obligation that management
56

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
measures using the cost-to-cost (input method). Management uses the input method measure of progress when it best depicts the transfer of value to the customer, which occurs as the Company incurs costs on its contract, generally related to fixed fee service contracts. Under the input method measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The cost calculation includes variables such as labor hours, allocation of overhead costs, research model costs, and subcontractor costs. Revenue is recorded proportionally as costs are incurred.
The principal considerations for our determination that performing procedures relating to DSA service revenue recognized over time using the input method is a critical audit matter are a high degree of auditor subjectivity and effort in performing procedures and evaluating audit evidence related to the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to DSA service revenue recognized over time using the input method, including controls over the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation, review of contracts, testing of budget versus actual costs incurred, and testing of revenue recognition. These procedures also included, among others (i) reading contracts and reports describing the results of services provided for a sample of DSA service contracts; (ii) testing management’s process for determining the amount of DSA service revenue recognized over time for a sample of DSA service contracts; (iii) evaluating the appropriateness of the input method used by management; (iv) evaluating the reasonableness of the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations through performing a retrospective comparison of actual costs incurred to historical estimated costs for completed service contracts; and (v) testing actual costs incurred for a sample of in-progress service contracts by examining evidence of costs incurred.

days in the United States and consistent with prevailing practice in international markets. A contract asset is recorded when a right to consideration in exchange for goods or services transferred to a customer is conditioned other than the passage of time. Client receivables are recorded separately from contract assets since only the passage of time is required before consideration is due. A contract liability is recorded when consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a contract. Contract liabilities are recognized as revenue after control of the products or services is transferred to the customer and all revenue recognition criteria have been met. Cumulative catch-up adjustments to revenue are periodically recorded that affect the corresponding contract asset or contract liability, including adjustments arising from a change in the measure of progress, a change in an estimate of the transaction price (including any changes in the assessment of whether an estimate of variable consideration), or a contract modification.

The Company estimates the fair value of contingent consideration obligations through valuation models, such as probability-weighted and option pricing models, that incorporate probability adjusted assumptions and simulations related to the achievement of the milestones and the likelihood of making related payments. The unobservable inputs used in the fair value measurements include the probabilities of successful achievement of certain financial targets, forecasted results or targets, volatility, and discount rates. The remaining maximum potential payments are approximately $ million, of which the value accrued as of December 30, 2023 is approximately $ million. The weighted average probability of achieving the maximum target is approximately %. The average volatility and weighted average cost of capital are approximately % and %, respectively.
Cash Flow Hedge
The Company is exposed to market fluctuations in interest rates as well as variability in foreign exchange rates. In November 2022, the Company entered into an interest rate swap with a notional amount of $ million to manage interest rate fluctuation related to floating rate borrowings under the Credit Facility, at a fixed rate of %.
In March 2023 and in conjunction with an amendment of the Credit Agreement (Second Amendment), the Company modified the variable rate on its interest rate swap from 1-month LIBOR to 1-month adjusted term SOFR. Effective with the modification, the Company will pay a fixed rate of % on its swap maturing November 2, 2024. The Company elected to apply the optional expedient in ASC 848, Reference Rate Reform, in connection with modifying its interest rate swap from LIBOR to SOFR that enabled it to consider the modification a continuation of the existing contract. As a result, the transition did not have an impact on the Company’s hedge accounting or a material impact to the Company’s financial statements.
Debt Instruments
The book value of the Company’s term and revolving loans, which are variable rate loans carried at amortized cost, approximates the fair value based on current market pricing of similar debt. As the fair value is based on significant other

(1) DSA includes accumulated impairment losses of $ billion, which were recognized in fiscal years 2008 and 2010.
Based on the Company’s quantitative goodwill impairment test, which was performed in the fourth quarter for each of the fiscal years 2023, 2022 and 2021, the fair value of each reporting unit exceeded the reporting unit’s book value and, therefore, goodwill was t impaired. After completing the quantitative testing for fiscal year 2023, all reporting units exceeded the carrying value by a significant amount except for the Biologics Solutions reporting unit which had a fair value that exceeded its carrying value by approximately %.
The increase in goodwill during fiscal year 2023 related to the acquisitions of Noveprim and SAMDI in the DSA reportable segment. The increase in goodwill during fiscal year 2022 related to the acquisition of Explora in the RMS reportable segment, partially offset by a decrease due to the Avian divestiture impacting the Manufacturing reportable segment.

Nonredeemable Noncontrolling Interest
The Company has an investment in an entity whose financial results are consolidated in the Company’s financial statements, as it has the ability to exercise control over this entity. The interest of the noncontrolling party in this entity has been recorded as noncontrolling interest within Equity in the accompanying consolidated balance sheets. The activity within the nonredeemable noncontrolling interest (net income less dividends declared) during fiscal years 2023, 2022, and 2021 was not significant.
Redeemable Noncontrolling Interests
The Company holds a % ownership interest in Noveprim. The Company has the right to purchase, and the noncontrolling interest holders have the right to sell, the remaining % equity interest at a fixed redemption value that ranges from $ million to $ million depending on when exercised, which represents a derivative embedded within the equity instrument. The Company has the call option right to purchase the remaining % equity up until one month after the sixth anniversary of closing the % equity stake (December 2029). On the first anniversary of the expiration of the call option (December 2030), a 12-month put option will be triggered giving the seller the right to require the Company to acquire the remaining shares of the seller for $ million. Additionally, the % noncontrolling interest holders may receive a dividend disproportionate to their equity ownership, which has an approximate fair value of $ million. The redeemable noncontrolling interest is measured at the greater of the amount that would be paid if settlement occurred as of the balance sheet date based on the accreted redemption value using the interest method and the carrying amount adjusted for net income (loss) attributable to the noncontrolling interest. As the noncontrolling interest holders have the ability to require the Company to purchase the remaining % interest, the noncontrolling interest is classified in the mezzanine section of the consolidated balance sheets, which is presented above the equity section and below liabilities.

% ownership interest in Vital River, a commercial provider of research models and related services in China as of December 31, 2022. The Company had the right to purchase, and the noncontrolling interest holders had the right to sell, the remaining % equity interest at a contractually defined redemption value, subject to a redemption floor, which represents a derivative embedded within the equity instrument. The redeemable noncontrolling interest was measured at the greater of the amount that would be paid if settlement occurred as of the balance sheet date based on the contractually defined redemption value and the carrying amount adjusted for net income (loss) attributable to the noncontrolling interest. The amount that the Company could be required to pay to purchase the remaining % equity interest was not limited. During the fourth quarter of fiscal 2023, the Company acquired the remaining % and as of December 2023, has paid $ million of the total $ million due. The remaining purchase price payable has been reclassified from the mezzanine section to Accrued liabilities on the consolidated balance sheet and is expected to be paid during fiscal year 2024.

In 2020, the Company acquired an % equity interest in a subsidiary, which included a % redeemable noncontrolling interest. In June 2022, the Company purchased an additional % interest in the subsidiary for $ million, resulting in a remaining noncontrolling interest of %. Beginning in 2024, the Company has the right to purchase, and the noncontrolling interest holders have the right to sell, the remaining % equity interest at its appraised value. The redeemable noncontrolling interest is measured at the greater of the amount that would be paid if settlement occurred as of the balance sheet date based on the appraised value and the carrying amount adjusted for net income (loss) attributable to the noncontrolling interest ($ million as of December 30, 2023) or a predetermined floor, which represents a derivative embedded within the equity instrument. The amount that the Company could be required to pay to purchase the remaining % equity interest is not limited.

The $ million decrease in unrecognized income tax benefits during fiscal year 2023 as compared to the corresponding period in 2022 is primarily attributable to prior year reductions to Canadian Scientific Research and Experimental Development (SR&ED) credits, partially offset by an additional year of SR&ED credit additions. The amount of unrecognized income tax benefits that, if recognized, would favorably impact the effective tax rate was $ million as of December 30, 2023 and $ million as of December 31, 2022. It is reasonably possible as of December 30, 2023 that the liability for unrecognized tax benefits for the uncertain tax position will decrease by approximately $ million over the next twelve-month period. The Company continues to recognize interest and penalties related to unrecognized income tax benefits in income tax expense. The total amount of cumulative accrued interest related to unrecognized income tax benefits as of December 30, 2023 and December 31, 2022 was $ million and $ million, respectively. Interest expense recorded as a component of income taxes was immaterial for all periods. There were accrued penalties related to unrecognized income tax benefits as of December 30, 2023 or as of December 31, 2022.
The Company conducts business in a number of tax jurisdictions. As a result, it is subject to tax audits on a regular basis including, but not limited to, such major jurisdictions as the U.S., the U.K., China, France, Germany, and Canada. With few exceptions, the Company is no longer subject to U.S. and international income tax examinations for years before 2019.
The Company and certain of its subsidiaries have ongoing tax controversies in the U.S., Canada, France, and India. The Company does not anticipate resolution of these audits will have a material impact on its consolidated financial statements.

The Company provides certain active employees an annual contribution into their DCP account of % of the employee’s base salary plus the lesser of their target annual bonus or actual annual bonus.
In addition to the DCP, certain officers and key employees also participate, or in the past participated, in the Company’s Executive Supplemental Life Insurance Retirement Plan (ESLIRP), which is a non-funded, non-qualified arrangement. Annual benefits under this plan will equal a percentage of the highest five consecutive years of compensation, offset by amounts payable under the U.S. Pension Plan and Social Security. In connection with the establishment of the DCP, certain active ESLIRP participants, who agreed to convert their accrued ESLIRP benefit to a comparable deferred compensation benefit, discontinued their direct participation in the ESLIRP. Instead, the present values of the accrued benefits of ESLIRP participants were credited to their DCP accounts, and future accruals are converted to present values and credited to their DCP accounts annually.
The net periodic benefit cost associated with these plans for fiscal years 2023, 2022 and 2021 totaled $ million, $ million and $ million, respectively.
The Company has invested in several corporate-owned key-person life insurance policies with the intention of using these investments to fund the ESLIRP and the DCP. Participants have no interest in any such investments. As of December 30, 2023 and December 31, 2022, the cash surrender value of these life insurance policies were $ million and $ million, respectively.

Litigation
On February 16, 2023, the Company was informed by the U.S. Department of Justice (DOJ) that in conjunction with the U.S. Fish and Wildlife Service (USFWS), it had commenced an investigation into the Company’s conduct regarding several shipments of non-human primates from Cambodia. On February 17, 2023 the Company received a grand jury subpoena requesting certain documents related to such investigation. The Company is aware of a parallel civil investigation being undertaken by the DOJ and USFWS. The Company is cooperating with the DOJ and the USFWS and believes that the concerns raised with respect to the Company’s conduct are without merit. The Company maintains a global supplier onboarding and oversight program incorporating risk-based due diligence, auditing, and monitoring practices to help ensure the quality of our supplier relationships and compliance with applicable U.S. and international laws and regulations, and has operated under the belief that all shipments of non-human primates it received satisfied the material requirements, documentation and related processes and procedures of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) documentation and related processes and procedures, which guides the release of each import by USFWS. Notwithstanding our efforts and good-faith belief, in connection with the civil investigation, the Company has voluntarily suspended future shipments of non-human primates from Cambodia to the United States until such time that the Company and USFWS can agree upon and implement additional procedures to reasonably ensure that non-human primates imported from Cambodia are purpose-bred. The Company continues to care for the Cambodia-sourced non-human primates from certain recent shipments in the United States. The carrying value of the inventory related to these shipments is approximately $ million as of December 30, 2023, which reflects the value of the shipments in accordance with the Company’s inventory accounting policy. On May 16, 2023, the Company received an inquiry from the Enforcement Division of the U.S. Securities and Exchange Commission (SEC) requesting it to voluntarily provide information, subsequently augmented with a document subpoena, primarily related to the sourcing of non-human primates, and the Company is cooperating with the request. We are not able to predict what action, if any, might be taken in the future by the DOJ, USFWS, SEC or other governmental authorities as a result of the investigations. None of the DOJ, USFWS or SEC has provided the Company with any specific timeline or indication as to when these investigations or, specific to the DOJ and USFWS, discussions regarding future processes and procedures, will be concluded or resolved. The Company cannot predict the timing, outcome or possible impact of the investigations, including without limitation any potential fines, penalties or liabilities.
A putative securities class action was filed on May 19, 2023 against the Company and a number of its current/former officers in the United States District Court for the District of Massachusetts. On August 31, 2023, the court appointed the State Teachers Retirement System of Ohio as lead plaintiff. An amended complaint was filed on November 14, 2023 that, among other things, included only James Foster, the Chief Executive Officer and David R. Smith, the former Chief Financial Officer as defendants along with the Company. The amended complaint asserts claims under §§ 10(b) and 20(a) of the Securities Exchange Act of 1934 (the Exchange Act) on behalf of a putative class of purchasers of Company securities from May 5, 2020 through February 21, 2023, alleging that certain of the Company’s disclosures about its practices with respect to the importation of non-human primates made during the putative class period were materially false or misleading. The Company filed a motion to dismiss. While the Company cannot predict the outcome of this matter, it believes the class action to be without merit and plans to vigorously defend against it. The Company cannot reasonably estimate the maximum potential exposure or the range of possible loss in association with this matter.
On November 8, 2023, a stockholder filed a derivative lawsuit in the U.S. District Court of the District of Delaware asserting claims on the Company’s behalf against the members of the Company’s Board of Directors and certain of the Company’s current/former officers (James Foster, the Chief Executive Officer; David R. Smith, the former Chief Financial Officer; and Flavia Pease, the current Chief Financial Officer). The complaint alleges that the defendants breached their fiduciary duties to the Company and its stockholders because certain of the Company’s disclosures about its practices with respect to the importation of non-human primates were materially false or misleading. The complaint also alleges that the defendants breached their fiduciary duties by causing the Company to fail to maintain adequate internal controls over securities disclosure and compliance with applicable law and by failing to comply with the company’s Code of Business Conduct and Ethics. The Company intends to file a motion to dismiss. While the Company cannot predict the outcome of this matter, it believes the derivative lawsuit to be without merit and plans to vigorously defend against it. The Company cannot reasonably estimate the maximum potential exposure or the range of possible loss in association with this matter.

Item 9A.    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, as of December 30, 2023, 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. 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.
(b)   Management’s Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Under the supervision and with the participation of our management, including our CEO and CFO, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our assessment and those criteria, management concluded that the Company maintained effective internal control over financial reporting as of December 30, 2023.
Our assessment of the effectiveness of our internal control over financial reporting as of December 30, 2023 excluded Noveprim, which was acquired by the Company in 2023. Noveprim, whose total assets and total revenues were excluded from the Company’s assessment, represented approximately less than 1%, respectively, of the related consolidated amounts as of and for the fiscal year ended December 30, 2023.
The effectiveness of our internal control over financial reporting as of December 30, 2023, has been audited by PricewaterhouseCoopers LLP, an Independent Registered Public Accounting Firm, as stated in their report which appears in Item 8, “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.
(c) Changes in Internal Controls Over Financial Reporting
During fiscal year 2023, there were no material 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 fourth quarter of 2023 that materially affected, or were reasonably likely to materially affect, the Company’s internal control over financial reporting.

Our Insider Trading Policy is posted on our website and can be accessed by selecting the “Corporate Governance” link at http://ir.criver.com.
E.    Code of Ethics
We have adopted a Code of Business Conduct and Ethics that applies to all of our employees and directors, including our principal executive officer, principal financial officer, principal accounting officer, controller, or persons performing similar functions. Our Code of Business Conduct and Ethics is posted on our website and can be accessed by selecting the “Corporate Governance” link at http://ir.criver.com. We will provide to any person, without charge, a copy of our Code of Business Conduct and Ethics. To obtain a copy, please mail a request to the Corporate Secretary, Charles River Laboratories International, Inc., 251 Ballardvale Street, Wilmington, MA 01887. Information on our website is not incorporated by reference in this annual report.
F.    Changes to Board Nomination Procedures
In December 2021, we amended our By-laws to include a proxy access by-law. Under our proxy access by-law, if a stockholder (or a group of up to 20 stockholders) who has owned at least 3% of our shares for at least three years and has complied with the other requirements set forth in our By-laws wants us to include director nominees (up to the greater of two nominees or 20% of the Board) in our proxy statement for an upcoming Annual Meeting, the nominations must be received in a timely manner, between 120 and 150 days prior to the anniversary of the date our proxy statement was first sent to stockholders in connection with the prior year’ annual meeting.
Item 11.    Executive Compensation
A.    Policies and Practices for Granting Certain Equity Awards.
The Compensation Committee of the Board of Directors is responsible for the review and approval of our policies and practices with respect to granting equity awards. The Compensation Committee typically targets the second quarter of our fiscal year, shortly after our annual meeting of shareholders and the release of our first quarter financial results, for granting annual stock awards to eligible recipients, absent an extraordinary event. The Compensation Committee believes this aligns timing of equity grants with the planning of annual salary increases (also in the second quarter of our fiscal year), allowing our managers to take a holistic view of total compensation.
The Compensation Committee seeks to structure equity grants so that they are awarded during an open window period as designated by our Insider Trading Policy, or, if Compensation Committee approval is provided during a non-window period, are typically made effective on the first business day following our press release with respect to financial results for the prior quarter. This policy is intended to ensure that options are awarded at a time when the exercise price fully reflects all recently disclosed information. In the case of new hires eligible to receive equity grants, grants are generally made on the first business day of the month following the date the individual commences employment.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
All grants to executive officers are made by the Compensation Committee itself and not pursuant to any delegated authority.
We have never had any programs, policies, or practices which are intended to time stock option grants with the release of material, non-public information in a manner that would provide advantageous option exercise prices to grant recipients. Option exercise prices are, in all cases, equal to the closing price of our common stock on the date of grant.
B.     Actions to Recover Erroneously Awarded Compensation
At no point during or after the last completed fiscal year did we prepare an accounting statement that required the recovery of erroneously awarded compensation pursuant to the company’s clawback policy, nor was there an outstanding balance as of the end of the last completed fiscal year of erroneously awarded compensation to be recovered from the application of the policy to a prior restatement.
The remainder of the information required by this Item will be included in the 2024 Proxy Statement under the sections captioned “2023 Director Compensation,” “Compensation Discussion and Analysis,” “Executive Compensation and Related Information,” “Compensation Committee Interlocks and Insider Participation” and “Report of Compensation Committee,” and is incorporated herein by reference thereto.

The information required by this Item will be included in the 2024 Proxy Statement under the sections captioned “Beneficial Ownership of Securities” and “Equity Compensation Plan Information” and is incorporated herein by reference thereto.
