NOTES TO UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

(dollars in thousands, except per share amounts)

1. Basis of Presentation

        The condensed consolidated interim financial statements are unaudited, and certain information and footnote disclosures related thereto normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been omitted in accordance with Rule 10-01 of Regulation S-X. In the opinion of management, the accompanying unaudited condensed consolidated financial statements were prepared following the same policies and procedures used in the preparation of the audited financial statements and reflect all adjustments (consisting of normal recurring adjustments) considered necessary to present fairly the financial position and results of operations of Charles River Laboratories International, Inc. (the "Company"). The results of operations for the interim periods are not necessarily indicative of the results for the entire fiscal year. These condensed consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 28, 2002.

        Certain amounts in prior-year financial statements and related notes have been reclassified to conform with current-year presentation.

2. Long-Term Debt

        On March 31, 2003, the Company entered into a revolving credit agreement which matures on March 31, 2006. The agreement permits the Company to borrow up to $100,000 at an interest rate based on, at the Company's option, the greatest of the Prime Rate, the Base CD Rate plus 1%, and the Federal Funds Effective Rate plus 0.5%, or LIBOR multiplied by the Statutory Reserve Rate plus a spread of 1.25% to 2.50% based on the leverage ratio of the Company and the aggregate borrowing under the revolving credit agreement. Interest is payable, ranging from monthly to semi-annually, based on the Company's option of interest rate selected. The credit agreement requires the Company to pay a quarterly commitment fee which ranges from 25 through 50 basis points annually on the undrawn balance, based on the leverage ratio of the Company. The agreement also requires the Company to remain in compliance with certain financial ratios as well as other restrictive covenants. No amounts were outstanding under the credit agreement as of June 28, 2003.

        On May 29, 2002, the Company repaid all of the outstanding senior secured term loan facilities, including $14,000 term loan A facility, $41,100 term loan B facility and $13,500 term loan C facility. The Company recorded a loss of $1,790 due to the write-off of deferred financing costs.

        On February 14, 2002, the Company completed a tender offer for $79,728 par value for all of its 13.5% senior subordinated notes. The Company recorded a loss of $27,479 due to the payment of premiums related to the early extinguishment of debt ($23,886), the write-off of deferred financing costs ($2,726) and issuance discounts ($867).

        Effective at the beginning of fiscal year 2003, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections." SFAS No. 145 eliminates the requirement that gains and losses from the extinguishment of debt be aggregated and, if material, classified as an extraordinary item, net of the related income tax effect. However, an entity would not be prohibited from classifying such gains and losses as extraordinary items so long as they are both unusual in nature and infrequent in occurrence. As the tender offer and repayment of the senior secured term loan facilities were not unusual in nature and infrequent in occurrence, the extraordinary loss before tax for

7

the three and six months ended June 29, 2002 of $1,790 and $29,269, respectively, was reclassified to loss on debt retirement. The related tax benefit for the three and six months ended June 29, 2002 of $698 and $11,415, respectively, was reclassified to the provision for income taxes in the condensed consolidated statements of income.

        On January 24, 2002, the Company issued $175,000 par value of senior convertible debentures through a private placement offering. On February 11, 2002, the Company issued an additional $10,000 par value of senior convertible debentures through the additional purchase option. The Company received approximately $179,450, net of underwriter discounts. The senior convertible debentures accrue interest at an initial annual rate of 3.5% which will reset (but not below the initial rate of 3.5% or above 5.25%) on August 1, 2007, August 1, 2012 and August 1, 2016. Interest is payable semi-annually in arrears, beginning August 1, 2002. The senior convertible debentures mature in 2022 and are convertible into shares of the Company's common stock at a conversion price of $38.87, subject to adjustment under certain circumstances. On or after February 5, 2005, the Company may redeem for cash all or part of the debentures that have not been previously converted at the redemption prices set forth in the purchase agreement. Holders may require the Company to repurchase for cash all or part of their debentures on February 1, 2008, February 1, 2013 or February 1, 2017 at a price equal to 100% of the par value of the debentures plus accrued interest up to but not including the date of repurchase. In addition, upon a change in control of the Company occurring on or prior to February 1, 2022, each holder may require the Company to repurchase all or a portion of such holder's debentures for cash. The Company used a portion of the net proceeds from the senior convertible debenture offering to retire all of the 13.5% senior subordinated notes through a tender offer.

3. Business Acquisitions

        Effective January 2, 2003, the Company acquired an additional 19% of the equity (404,321 common shares) of Charles River Japan from Ajinomoto Company, Inc., the minority interest partner, which has increased the Company's ownership to 85% of the outstanding shares. The purchase price for the equity was 1.3 billion yen, or $10,841, which was paid in cash. The Company recorded goodwill of $2,553 based on preliminary purchase price allocation in the first quarter. The Company has reallocated this amount to fixed assets based on an independent valuation of these fixed assets, which was completed during the second quarter. Charles River Japan is an extension of the Company's research model business.

        During the first quarter of 2003, the Company recorded a deferred tax liability of $6,000 associated with prior-year acquisitions. This resulted in an increase in goodwill of $6,000.

        On June 7, 2002, Charles River Europe GmbH, a subsidiary of the Company, acquired 100% of the voting equity interests of privately-held Biological Laboratories Europe Limited (BioLabs). Consideration, including acquisition expenses, was $22,900, net of cash acquired of $2,998. The consideration consisted of $21,012 in cash and $1,888 in future payments, of which approximately $629 is recorded in current liabilities and the remaining amount is recorded in long-term liabilities, which are to be paid to certain former shareholders of BioLabs over a three-year period. BioLabs, located in western Ireland, provides a broad range of services supporting the discovery, development and manufacturing of pharmaceutical, medical devices and animal and human health products. BioLabs was

8

acquired to strengthen the Company's existing biomedical products and services segment by adding new capabilities to service the large and growing global animal health and medical device industry. The acquisition was recorded as a purchase business combination in accordance with SFAS No. 141.

        The following selected unaudited pro forma consolidated results of operations are presented as if each acquisition had occurred as of the beginning of 2002, after giving effect to certain adjustments for additional interest expense and related income tax effects. The pro forma data is for informational purposes only and does not necessarily reflect the results of operations had the companies operated as one during the period. No affect has been given for synergies, if any, that may have been realized through acquisitions.

        Refer to Note 7 for further discussion of the method of computation of earnings per share.

4. Litigation Settlement

        On March 28, 2003, the Company's French subsidiaries, which are included in the biomedical products and services segment, settled a pending breach of contract claim against a customer. The Company's French subsidiaries had previously been awarded damages of approximately $4,600 by the Commercial Court of Lyon and the damages award was stayed pending appeal by the customer at the French Supreme Court. The final settlement of this dispute was for a gross value of approximately $3,750, resulting in the retention by the Company's French subsidiaries of the amount previously deposited by the customer, pursuant to the order of the Commercial Court of Lyon and recorded in deferred income in the consolidated balance sheet. During 2000, the Company recognized approximately $350 of the damages award to offset a portion of subcontractor costs incurred based on the indemnification clause in the original customer agreement. After legal and related expenses, the Company's French subsidiaries recorded a net gain for the retained settlement amount of $2,908, which was recorded in the first quarter of 2003 as other operating income in the condensed consolidated statements of income.

5. Asset Impairment Charge

        During the first quarter of 2003, the Company re-evaluated the marketability of certain long-lived assets related to a biopharmaceutical production facility in Maryland, which is included in the biomedical products and services segment, due to a significant decline in market interest in purchasing these assets. Since the Company was unable to locate a buyer for these assets, an impairment charge

9

was recognized because future undiscounted cash flows were estimated to be insufficient to recover the related book value. The Company recorded an asset impairment charge of $3,655 for the write-down of those assets including a net write-down of leasehold improvements of $2,195 and machinery and equipment of $1,460. The charge was recorded as other operating expenses in the condensed consolidated statements of income.

6. Restructuring Charges

        During the second quarter of 2003, the Company recorded a charge of $871 for severance to employees who were terminated as part of a cost savings program. The Company recorded $613 of the charge to cost of services provided and the remaining to selling, general and administrative expenses in the condensed consolidated statements of income. Approximately 100 employees, mainly technicians, technical support and administrative staff, were terminated as part of the cost savings program.

        During the fourth quarter of 2001, the Company recorded restructuring charges of $1,788, including asset disposals of $1,041, employee separation of $477 and other charges of $270, associated with the closure of a San Diego, California, facility. The restructuring plan included the termination of approximately 40 employees and the exit of a facility utilized under an operating lease. All terminated employees had separated from the Company by the end of the third quarter of 2002. During 2002, the Company recorded an additional $292 charge relating to the remaining lease obligation at the facility based on the Company's revised estimate of expected sublease income generated over the remaining lease term.

        During the fourth quarter of 2000, the Company recorded restructuring charges of $1,290, including asset disposal of $212, associated with the closure of a facility in France. During 2001, the Company recorded additional charges of $1,915, which included a write down of assets held for sale of $400 and additional severance payments and other related expenses of $1,515, relating to the settlement of labor disputes which originated during the first quarter of 2001. Approximately 60 employees were terminated as a result of the restructuring. All terminated employees had separated from the Company by the end of the third quarter 2002.

        A summary of the activities associated with the above charges and the related liabilities balance are as follows:

The Company has closed both the San Diego facility and the French facility and expects all the above reserves to be fully utilized by 2004.

7. Earnings per Share

        Basic earnings per share for the three and six months ended June 28, 2003 and June 29, 2002 were computed by dividing earnings available to common shareholders for these periods by the weighted average number of common shares outstanding in the respective periods. The weighted average number of common shares outstanding in the three and six months ended June 28, 2003 and June 29, 2002 have been adjusted to include common stock equivalents for the purpose of calculating diluted earnings per share for these periods.

        Options to purchase 1,888,065 and 31,550 shares were outstanding at June 28, 2003 and June 29, 2002, respectively, but were not included in computing diluted earnings per share in each of the respective three months ended because their inclusion would have been anti-dilutive. Options to purchase 1,868,065 and 66,650 shares were outstanding at June 28, 2003 and June 29, 2002, respectively, but were not included in computing diluted earnings per share in each of the respective six months ended because their inclusion would have been anti-dilutive.

        Basic weighted average shares outstanding for the three and six months ended June 28, 2003 and June 29, 2002 excluded the weighted average impact of 20,000 contingently issuable shares. In addition, weighted average shares outstanding for the three and six months ended June 28, 2003 and June 29, 2002 excluded the weighted average impact of 61,669 and 11,500 shares, respectively, of non-vested fixed restricted stock awards.

        The following table illustrates the reconciliation of the numerator and denominator of the basic and diluted earnings per share computations:

11

8. Stock-Based Compensation Plans

        As permitted under SFAS No. 123, "Accounting for Stock-Based Compensation," the Company accounts for its stock-based compensation plans using the intrinsic value method prescribed by Accounting Principles Board Opinion (APB) No. 25, "Accounting for Stock Issued to Employees" and Financial Accounting Standards Board (FASB) Interpretation No. 44 (FIN 44), "Accounting for Certain Transactions Involving Stock Compensation—an interpretation of APB Opinion No. 25." Also, the Company accounts for variable restricted stock grants under the provisions of FASB Interpretation No. 28, "Accounting for Stock Appreciation Rights and Other Variable Stock Options Award Plans." The Company recognizes compensation expenses for fixed and variable restricted stock grants over the restriction period.

        SFAS No. 123 requires the presentation of certain pro forma information as if the Company had accounted for its employee stock options under the fair value method. For purposes of this disclosure, the fair value of the fixed option grants was estimated using the Black-Scholes option pricing model.

        The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility and expected life of the options. Because the Company's employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimates, in management's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options. However, for each period presented, management believes the Black-Scholes model is the most appropriate option valuation model.

        Had compensation expense for the Company's option grants been recognized consistent with the provisions of SFAS No. 123 as amended by SFAS No. 148, "Accounting for Stock-Based Compensation—Transition and Disclosure, an Amendment of FASB Statement No. 123", the

12

Company's net income and earnings per share for the three and six months ended June 28, 2003 and June 29, 2002 would have been reduced to the pro forma amounts indicated below:

9. Supplemental Balance Sheet Information

        The composition of inventories is as follows:

        Inventories are stated at the lower of cost or market. Cost is determined principally on the average cost method. Costs for large animals are accumulated in inventory until the animals are sold.

13

        The composition of property, plant and equipment is as follows:

10. Comprehensive Income

        The components of comprehensive income for the three and six months ended June 28, 2003 and June 29, 2002 are set forth below:

11. Commitments and Contingencies

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

        As of June 28, 2003 and December 28, 2002, the Company had $5,258 and $4,708 outstanding under letters of credit, respectively.

12. Business Segment Information

        The following table presents sales and other financial information by product line segment for the three and six months ended June 28, 2003 and June 29, 2002. Sales to unaffiliated customers represent

14

net sales originating in entities primarily engaged in either biomedical products and services or research models.

        A reconciliation of segment operating income to consolidated operating income is as follows:

        A summary of unallocated corporate overhead consists of the following:

15

        Other general unallocated corporate expenses consist of various costs including those associated with senior executive salaries and departments such as corporate accounting, legal and investor relations.

        A summary of total assets of each business segment is as follows:

13. Goodwill and Other Intangible Assets

        The following table displays goodwill and other intangible assets not subject to amortization and other intangible assets that continue to be subject to amortization:

16

        The changes in the gross carrying amount and accumulated amortization of goodwill from December 28, 2002 to June 28, 2003 are as follows:

        Estimated amortization expense for each of the next five years is as follows:

14. Recently Issued Accounting Standards

        In May 2003, the FASB issued SFAS No.150, "Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity." This statement establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. SFAS No. 150 is effective for financial instruments entered into or modified after May 31, 2003. This statement does not result in any material change to the Company's existing reporting.

        In April 2002, the FASB issued SFAS No. 145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections." SFAS No. 145 eliminates the requirement that gains and losses from the extinguishment of debt be aggregated and, if material, classified as an extraordinary item, net of the related income tax effect. However, an entity would not be prohibited from classifying such gains and losses as extraordinary items so long as they are both unusual in nature and infrequent in occurrence. The Company adopted the provisions of SFAS No. 145 as of the beginning of fiscal year 2003 and reclassified losses on extinguishment of debt that had been classified as an extraordinary item in prior periods presented.

        In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." SFAS No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When the liability is initially recorded, the entity is required to capitalize the cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. The Company adopted SFAS No. 143 as of the beginning of fiscal year

17

2003. The adoption of this standard did not have any material effect on the Company's consolidated financial statements.

        In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities," which nullifies EITF Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)." SFAS No. 146 requires a liability for a cost associated with an exit or disposal activity be recognized and measured initially at its fair value in the period in which the liability is incurred. If fair value cannot be reasonably estimated, the liability shall be recognized initially in the period in which fair value can be reasonably estimated. In periods subsequent to the initial measurement, changes to the liability resulting from a revision to either the timing or the amount of estimated cash flows shall be recognized as an adjustment to the liability in the period of the change. The Company adopted the provisions of SFAS No. 146 as of the beginning of fiscal year 2003. The adoption of the standard did not have any material effect on the Company's consolidated financial statements.

        On November 25, 2002, the FASB issued FASB Interpretation No. 45 (FIN 45), "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an interpretation of SFAS Nos. 5, 57, and 107 and Rescission of FASB Interpretation No. 34." FIN 45 clarifies the requirements of SFAS No. 5, "Accounting for Contingencies," relating to the guarantor's accounting for, and disclosure of, the issuance of certain types of guarantees. FIN 45 requires that, upon issuance of a guarantee, the guarantor must recognize a liability for the fair value of the obligation. FIN 45 is applicable to guarantees that encompass guarantees based on changes in an underlying asset, liability or equity security, guarantees that are made on behalf of another entity's performance, certain indemnification agreements and indirect guarantees of the indebtedness of others. The recognition and measurement provisions of FIN 45 are effective prospectively for guarantees issued or modified after December 31, 2002. The disclosure requirements are effective for reporting periods ending after December 15, 2002. The Company has made the required disclosures in the consolidated financial statements as of December 28, 2002. The adoption of the standard did not have any material effect on the Company's consolidated financial statements.

        In November 2002, the EITF reached final consensus on EITF Issue No. 00-21, "Accounting for Revenue Arrangements with Multiple Deliverables." EITF Issue No. 00-21 addresses certain aspects of a vendor's accounting for arrangements under which it will perform multiple revenue-generating activities. It provides additional guidance as to how revenue should be measured and allocated to the separate units of accounting. EITF Issue No. 00-21 is effective prospectively for revenue arrangements entered into during fiscal periods beginning after June 15, 2003. The Company believes the adoption of the standard will not have a material effect on the Company's consolidated financial statements.

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

Overview

        We are a leading provider of critical research tools and integrated support services that enable innovative and efficient drug discovery and development. We are the global leader in providing the animal research models required in research and development for new drugs, devices and therapies and have been in business for more than 55 years.

        Total net sales for the second quarter of 2003 were $154.4 million, an increase of 13.1% over the same period last year. Favorable foreign currency translation contributed approximately 4.5% to the net sales gain. Net sales attributable to Biological Laboratories Europe Limited (BioLabs) and Springborn Laboratories, Inc. (Springborn), which we acquired in 2002, contributed 4.6% to the net sales gain. Our gross margin increased to 38.6% of total net sales, compared to 38.4% of total net sales for the same period last year, due primarily to increased margins in the research models business from higher sales and improved capacity utilization. During the second quarter we implemented a cost savings program for our development services unit of biomedical products and services. The cost savings program resulted in a severance charge of $0.9 million in the second quarter of 2003 and we believe will generate ongoing cost savings of approximately $6.0 million of compensation on an annual basis. Operating income for the second quarter of 2003, which includes the charge for the cost savings program rose to $35.0 million, an increase of 15.2% over the same period last year. Operating margin increased to 22.7% compared to 22.3% achieved in the second quarter of last year. Net income for the second quarter of 2003 was $20.6 million compared to $16.3 million for the second quarter of 2002. Last year's second quarter results included a charge of $1.8 million for the early retirement of debt.

        On a year to date basis, total net sales were $306.5 million, an increase of 13.4% over the same period last year. Favorable foreign currency translation contributed approximately 4.6% to the net sales gain. Net sales attributable to BioLabs and Springborn, which we acquired in 2002, contributed 4.9% to the net sales gain. Our gross margin increased to 38.4% of total net sales, compared to 37.9% of total net sales for the same period last year. The year to date results include a net charge of $0.8 million. Operating income on a year to date basis increased 17.1% over last year. On a year to date basis, the operating margin increased to 22.5% compared to 21.7% for last year. Net income was $39.9 million compared to $14.1 million last year. Last year's results included a charge of $29.3 million for the early retirement of debt.

        We have two segments for financial reporting purposes: biomedical products and services and research models.

        Our biomedical products and services segment consists of our four business units: discovery services, development services, in vitro technology and vaccine support products. Our biomedical products and services segment represented 58.5% of total net sales in the second quarter of 2003. Sales for this segment increased 12.9% over the same period last year. Favorable foreign currency translation contributed approximately 2.3% of the net sales gain. The acquisitions of BioLabs and Springborn in 2002 contributed 7.9% to the net sales growth in the second quarter of 2003. Through the second quarter of 2003, this segment continued to be adversely affected by our development services business unit. During the second quarter, we completed a cost savings program for our development services unit. The cost savings program resulted in a severance charge of $0.9 million in the second quarter of 2003 and we believe will generate ongoing cost savings of approximately $6.0 million of compensation on an annual basis. We continue to believe that the decline in spending on development services, such as ours, by pharmaceutical and biotechnology drug companies that we experienced in the fourth quarter of 2002 and through the second quarter of 2003 will continue to adversely affect the growth of our biomedical products and services segment at least through the end of fiscal 2003. During the second quarter, we began to see improving levels of customer demands in certain of our development services businesses, particularly large animal and reproductive toxicology, as well as strong growth in

19

interventional pharmacology services. The charge for the cost savings program and the decrease in sales at this business segment resulted in a decrease in operating income to 18.5% for the second quarter of 2003 from 20.4% for the second quarter of 2002.

        Sales on a year to date basis for our biomedical products and services segment increased 13.0% over the same period last year. Operating income decreased slightly to 17.1% of net sales through the second quarter of 2003, including the $0.9 million charge for the cost savings program, compared to 19.4% through the second quarter of 2002.

        Our research models business segment represented 41.5% of total net sales for the second quarter of 2003. Net sales for this segment increased 13.3% over the same period in 2002. Favorable foreign currency translation contributed approximately 7.6% of the net sales gain. The net sales increase drove an 18.2% improvement in operating income, which increased to 35.0% of total net sales for the second quarter of 2003, compared to 33.6% of net sales for the same period last year.

        Our research models business net sales on a year to date basis increased 13.9% over the same period in 2002.

The increase was primarily due to our 2002 acquisitions and continued growth in outsourcing of discovery services. The acquisitions of BioLabs and Springborn contributed $6.3 million to the net sales growth for the three months ended June 28, 2003. Our discovery services sales growth continued to be driven by our transgenic services and contract staffing business units. Our vaccine support business sales increased for the three months ended June 28, 2003 due to increased product sales and increased pricing and the consolidation of our Mexican joint venture. The consolidation of our Mexican joint venture added $1.9 million of sales for the three months ended June 28, 2003. Our development business sales increased primarily due to the 2002 acquisitions of BioLabs and Springborn, partially offset by reduced safety assessment studies, business at our contract biopharmaceutical production facility and biosafety testing.

        Research Models.    Net sales of research models for the three months ended June 28, 2003 were $64.1 million, an increase of $7.6 million, or 13.3%, from $56.5 million for the three months ended June 29, 2002.

Liquidity and Capital Resources

        The following discussion analyzes liquidity and capital resources by operating, investing and financing activities as presented in the Company's condensed consolidated statements of cash flows.

        Our principal sources of liquidity are cash flows from operations and proceeds from our debt and equity offerings.

24

        On March 31, 2003, the Company entered into a revolving credit agreement which matures on March 31, 2006. The agreement permits the Company to borrow up to $100.0 million at an interest rate based on, at the Company's option, the greatest of the Prime Rate, the Base CD Rate plus 1%, and the Federal Funds Effective Rate plus 0.5%, or LIBOR multiplied by the Statutory Reserve Rate plus a spread of 1.25% to 2.50% based on the leverage ratio of the Company and the aggregate borrowing under the revolving credit agreement. Interest is payable based on the Company's option of interest rate selected, which ranges from monthly to semi-annually. The credit agreement requires the Company to pay a quarterly commitment fee which ranges from 25 through 50 basis points on the undrawn balance, based on the leverage ratio of the Company. The agreement also requires the Company to remain in compliance with certain financial ratios as well as other restrictive covenants. No amounts were outstanding under the credit agreement as of June 28, 2003.

        Effective January 2, 2003, we acquired an additional 19% of the equity (404,321 common shares) of our then 66% equity joint venture company, Charles River Japan, from Ajinomoto Company, Inc. The purchase price for the equity was 1.3 billion yen, or $10.8 million, which was paid in cash.

        In connection with the acquisition of Springborn in 2002, we entered into a $6.0 million three-year unsecured subordinated note. The note is payable in three equal annual installments of principal, together with interest accrued in arrears commencing on October 1, 2003. Interest is payable based on the one-month LIBOR rate plus 1%, which equaled 2.81% at June 28, 2003.

        On January 24, 2002, we issued $175.0 million par value of senior convertible debentures through a private placement offering. On February 11, 2002, we issued an additional $10.0 million par value of the senior convertible debentures through the additional purchase option. The senior convertible debentures accrue interest at an initial annual rate of 3.5% which will be reset (but not below the initial rate of 3.5% or above 5.25%) on August 1, 2007, August 1, 2012 and August 1, 2016. Interest is payable semi-annually in arrears, beginning August 1, 2002. The senior convertible debentures will mature in 2022 and are convertible into shares of our common stock at a fixed conversion price of $38.87, subject to adjustments under certain circumstances. On or after February 5, 2005, we may redeem for cash all or part of the debentures that have not been previously converted at the redemption prices set forth in the purchase agreement. Holders may require us to repurchase for cash all or part of their debentures on February 1, 2008, February 1, 2013 or February 1, 2017 at a price equal to 100% of the principal amount of the debentures plus accrued interest. In addition, upon a change in control of our Company occurring on or prior to February 1, 2022, each holder may require us to repurchase all or a portion of such holder's debentures for cash. In 2002, we used a portion of the net proceeds from the senior convertible debenture offering to retire all of the 13.5% senior subordinated notes through a tender offer.

        During 2002, we repaid our outstanding senior secured term loan facilities and terminated our revolving credit facility. As a result of the termination of our revolving credit facility, we were required to transfer $5.0 million into a separate bank account to support outstanding letters of credit. This amount is reported as restricted cash in our consolidated financial statements as of December 28, 2002. During the second quarter of 2003, the restriction was lifted due to the new revolving credit agreement entered into by the Company. As of June 28, 2003 and December 28, 2002, we had approximately $5.3 million and $4.7 million outstanding under letters of credit, respectively.

        Cash and cash equivalents totaled $144.3 million at June 28, 2003, compared with $122.5 million at December 28, 2002.

        Net cash provided by operating activities for the six months ended June 28, 2003 and June 29, 2002 was $49.3 million and $53.6 million, respectively. The decrease in cash provided by operations is primarily the result of our improved collection efforts which began in early 2002. Our days sales outstanding decreased to 63 days as of June 28, 2003, from 70 days as of June 29, 2002, but remained constant with the DSO of 64 days as of December 28, 2002.

25

        Net cash used in investing activities during the six months ended June 28, 2003 and June 29, 2002 was $25.0 million and $33.8 million, respectively. The cash used in investing activities during the six months ended June 28, 2003 relates to the acquisition of an additional 19% of equity in Charles River Japan for $10.8 million and capital expenditures of $14.5 million. For the first six months ended June 29, 2002, the cash used in investment activities related to the acquisition of BioLabs and capital expenditures of $14.3 million.

        Financing activities during the six months ended June 28, 2003 used cash of $3.9 million and provided cash of $4.4 million during the six months ended June 29, 2002. During March 2002, we issued $185.0 million par value of senior convertible debentures and used $103.6 million of the proceeds to repay all of the 13.5% senior subordinated notes, including a premium of $23.9 million.

        We anticipate that our operating cash flows, together with borrowings under our new revolving credit facility, will be sufficient to meet our anticipated future operating expenses, capital expenditures and debt service obligations as they become due. We currently intend to retain any earnings to finance future operations and expansion.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

        Certain of our financial instruments are subject to market risks, including interest rate risk and foreign currency exchange rates.

        The fair value of long-term fixed interest rate debt is subject to interest rate risk. In addition, the fair value of our senior convertible debentures would be impacted by our stock price. The estimated fair value of our long-term debt at June 28, 2003 was $209.1 million. Fair values were determined from available market prices, using current interest rates and terms to maturity.

        During 2002, we terminated our revolving credit facility and repaid all of our variable-rate term loans. Our senior convertible debentures accrue interest at an initial rate of 3.5%, which will be reset (but not below the initial rate of 3.5% or above 5.25%) on August 1, 2007, August 1, 2012 and August 1, 2016. Fluctuations in interest rates will not affect the interest payable on the senior convertible debentures, which is fixed through August 1, 2007.

        We generally do not use financial instruments for trading or other speculative purposes.

        We also have exposure to some foreign currency exchange rate fluctuations for the cash flows received from our foreign affiliates. This risk is mitigated by the fact that their operations are principally conducted in their respective local currencies.

Item 4. Controls and Procedures.

        Based on their evaluation required by paragraph (b) of the Exchange Act Rules 13a-15 or 15d-15, 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) under the Securities Exchange Act of 1934 (the "Exchange Act") are effective as of June 28, 2003 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.

        There were no changes in the Company's internal controls 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 28, 2003 that materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

Recently Issued Accounting Standards

        In May 2003, the FASB issued SFAS No.150, "Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity." This statement establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. SFAS No. 150 is effective for financial instruments entered into or modified after May 31, 2003. This statement does not result in any material change to the Company's existing reporting.

        In April 2002, the FASB issued SFAS No. 145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections." SFAS No. 145 eliminates the requirement that gains and losses from the extinguishment of debt be aggregated and, if material, classified as an extraordinary item, net of the related income tax effect. However, an entity would not be prohibited from classifying such gains and losses as extraordinary items so long as they are both unusual in nature and infrequent in occurrence. The Company adopted the provisions of SFAS No. 145 as of the beginning of fiscal year 2003 and reclassified losses on extinguishment of debt that had been classified as an extraordinary item in prior periods presented.

        In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." SFAS No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When the liability is initially recorded, the entity is required to capitalize the cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. The Company adopted SFAS No. 143 as of the beginning of fiscal year 2003. The adoption of this standard did not have any material effect on the Company's consolidated financial statements.

        In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities," which nullifies EITF Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)." SFAS No. 146 requires a liability for a cost associated with an exit or disposal activity be recognized and measured initially at its fair value in the period in which the liability is incurred. If fair value cannot be reasonably estimated, the liability shall be recognized initially in the period in which fair value can be reasonably estimated. In periods subsequent to the initial measurement, changes to the liability resulting from a revision to either the timing or the amount of estimated cash flows shall be recognized as an adjustment to the liability in the period of the change. The Company adopted the provisions of SFAS No. 146 as of the beginning of fiscal year 2003. The adoption of the standard did not have any material effect on the Company's consolidated financial statements.

        On November 25, 2002, the FASB issued FASB Interpretation No. 45 (FIN 45), "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an interpretation of SFAS Nos. 5, 57, and 107 and Rescission of FASB Interpretation No. 34." FIN 45 clarifies the requirements of SFAS No. 5, "Accounting for Contingencies," relating to the guarantor's accounting for, and disclosure of, the issuance of certain types of guarantees. FIN 45 requires that, upon issuance of a guarantee, the guarantor must recognize a liability for the fair value of the obligation. FIN 45 is applicable to guarantees that encompass guarantees based on changes in an underlying asset, liability or equity security, guarantees that are made on behalf of another entity's performance, certain indemnification agreements and indirect guarantees of the indebtedness of others. The recognition and measurement provisions of FIN 45 are effective prospectively for guarantees issued or modified after December 31, 2002. The disclosure requirements are effective for reporting periods ending after December 15, 2002. The Company has made the required disclosures in the consolidated financial statements as of December 28, 2002. The adoption of the standard did not have any material effect on the Company's consolidated financial statements.

        In November 2002, the EITF reached final consensus on EITF Issue No. 00-21, "Accounting for Revenue Arrangements with Multiple Deliverables." EITF Issue No. 00-21 addresses certain aspects of a vendor's accounting for arrangements under which it will perform multiple revenue-generating activities. It provides additional guidance as to how revenue should be measured and allocated to the separate units of accounting. EITF Issue No. 00-21 is effective prospectively for revenue arrangements entered into during fiscal periods beginning after June 15, 2003. The Company believes the adoption of the standard will not have a material effect on the Company's consolidated financial statements.
