Special Note on Factors Affecting Future Results

This Quarterly Report on Form 10-Q contains forward-looking statements regarding future events and the future results of Charles River Laboratories International, Inc. (“Charles River”) that are based on current expectations, estimates, forecasts, and projections about the industries in which Charles River operates and the beliefs and assumptions of our management. Words such as “expect,” “anticipate,” “target,” “goal,” “project,” “intend,” “plan,” “believe,” “seek,” “estimate,” “will,” “likely,” “may,” “designed,” “would,” “future,” “can,” “could” and other similar expressions that are predictions of or indicate future events and trends or which do not relate to historical matters are intended to identify such forward-looking statements. These statements are based on current expectations and beliefs of Charles River and involve a number of risks, uncertainties, and assumptions that are difficult to predict. For example, we may use forward-looking statements when addressing topics such as: future demand for drug discovery and development products and services, including the outsourcing of these services; future actions by our management; the outcome of contingencies; changes in our business strategy; changes in our business practices and methods of generating revenue; the development and performance of our services and products; market and industry conditions, including competitive and pricing trends; changes in the composition or level of our revenues; our cost structure; the impact of acquisitions and dispositions; the timing of the opening of new and expanded facilities; our expectations with respect to sales growth, efficiency improvements and operating synergies; changes in our expectations regarding future stock

option, restricted stock and other equity grants to employees and directors; changes in our expectations regarding our stock repurchases; assessing (or changing our assessment of) our tax positions for financial statement purposes; and our cash flow and liquidity. You should not rely on forward-looking statements because they are predictions and are subject to risks, uncertainties and assumptions that are difficult to predict. Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this document or in the case of statements incorporated by reference, on the date of the document incorporated by reference. Factors that might cause or contribute to such differences include, but are not limited to, those discussed in our Annual Report on Form 10-K for the year ended December 30, 2006 under the section entitled “Risks Related to Our Business and Industry,” the section of this Quarterly Report on Form 10-Q entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in our press releases and other financial filings with the Securities and Exchange Commission. We have no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or risks. New information, future events or risks may cause the forward-looking events we discuss in this report not to occur.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED
INTERIM FINANCIAL STATEMENTS
(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. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the accompanying unaudited condensed consolidated financial statements were prepared following the same policies and procedures used in the preparation of the audited financial statements and reflect all adjustments (consisting of normal recurring adjustments) considered necessary to state fairly the 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 30, 2006.

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

2. Discontinued Operations

The consolidated financial statements have been reclassified to segregate, as discontinued operations, the assets and liabilities, operating results and cash flows, of the businesses being discontinued for all periods presented. Operating results from discontinued operations are as follows:

	Three Months Ended							Six Months Ended
	June 30, 2007			July 1, 2006				June 30, 2007				July 1, 2006
Net sales		$	174		$	30,927			$	546		$	60,556
Income (loss) from operations of discontinued businesses, before income taxes		$	169		$	(6,668	)		$	(510	)	$	(135,070	)
Provision for income taxes		54			364				(161		)	592
Income (loss) from operations of discontinued businesses, net of taxes		$	115		$	(7,032	)		$	(349	)	$	(135,662	)

Assets and liabilities of discontinued operations at June 30, 2007 and December 30, 2006 consisted of the following:

	June 30, 2007			December 30, 2006
Current assets		$	1,123		$	6,330
Long-term assets		4,217			751

(dollars in thousands, except per share amounts)

Current assets included accounts receivable, prepaid income taxes and other current assets. Non-current assets included property, plant and equipment, goodwill and other intangible assets. Current liabilities consisted of accounts payable, deferred income and accrued expenses.

During 2006, the Company sold Phase II-IV of its clinical services business. Actions to initiate this sale began during the first quarter of fiscal 2006. Accordingly, management performed appropriate goodwill impairment and asset impairment tests for the clinical business segment. As a result, the Company recorded charges of $129,187 to write down the value of the goodwill associated with the clinical business in the first quarter of 2006.

In the second quarter of 2006, taking into account the planned divestiture of the Phase II-IV Clinical Services business, the Company performed an impairment test on the long-lived assets of the Clinical Phase II-IV business. Based on this analysis, the Company determined that the book value of assets assigned to the Clinical Phase II-IV business exceeded its future cash flows, which included the proceeds from the sale of the business, and therefore, recorded an impairment of the assets of $3,900 in the second quarter of 2006.

In addition, during the second quarter of 2006 the Company made a decision to close its Interventional and Surgical Services (ISS) business, which was formerly included in the Preclinical Services segment. The Company performed an impairment test on the long-lived assets of the ISS business and based on that analysis, determined that the book value of the ISS assets exceeded the future cash flows of the ISS business. Accordingly, an impairment charge of $1,070 was recorded in the second quarter of 2006.

3. Impairment and Other Charges

During the second quarter of 2006, the Company recorded charges of $5,300 associated with actions designed to improve operating efficiency and profitability. In the Research Models and Services segment the charges were $2,334 for closure of two small vaccine facilities and a management consolidation in the Transgenic Services business. In the Preclinical Services segment, the charges were $2,966 for headcount reductions, primarily in the Montréal facility and closure of a small Interventional and Surgical Services operation in Ireland.

4. Business Acquisitions

On June 14, 2007, the Company closed its joint venture with Shanghai BioExplorer Co., Ltd., a Shanghai, China-based provider of preclinical services, to form Charles River Laboratories Preclinical Services—China. The Company paid $2,400 in cash for a 75% ownership interest in the joint venture. Additionally, as part of the agreement, the joint venture purchased the net assets of Shanghai BioExoplorer for a purchase price of $1,350 including transaction costs of $550. Intangible assets of $870 were recorded by the joint venture based on the preliminary purchase price allocation.

8. Long-Term Debt

On July 31, 2006, the Company amended and restated its $660,000 credit agreement to reduce the current interest rate, modify certain restrictive covenants and extend the term. The amount of debt outstanding under the original $660,000 credit agreement remained the same at the time of amendment. The now $428,000 credit agreement provides for a $156,000 U.S. term loan facility, a $200,000 U.S. revolving facility, a C$57,800 term loan facility and a C$12,000 revolving facility for a Canadian subsidiary, and a GBP 6,000 revolving facility for a U.K. subsidiary. The $156,000 term loan facility matures in 20 quarterly installments with the last installment due June 30, 2011. The $200,000 U.S. revolving facility matures on July 31, 2011 and requires no scheduled payment before that date. Under specified circumstances, the $200,000 U.S. revolving facility may be increased by $100,000. The Canadian term loan is repayable in full by June 30, 2011 and requires no scheduled prepayment before that date. The Canadian and U.K. revolving facilities mature on July 31, 2011 and require no scheduled prepayment before that date. The interest rate applicable to the Canadian term loan and the Canadian and U.K. revolving loans under the credit agreement is the adjusted LIBOR rate in its relevant currency plus an interest rate margin based upon the Company’s leverage ratio. The interest rates applicable to term loans and revolving loans under the credit agreement are, at the Company’s option, equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) or the adjusted LIBOR rate plus an interest rate margin based upon the Company’s leverage ratio. Based on the Company’s leverage ratio, the margin range for LIBOR based loans is 0.625% to 0.875%. The interest rate margin was 0.75% as of June 30, 2007 and is secured by the stock of certain subsidiaries as well as certain U.S. assets. The $428,000 credit agreement includes certain customary representations and warranties, events of default and negative and affirmative covenants including the ratio of consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) to consolidated interest expense, for any period of four consecutive fiscal quarters, of no less than 3.5 to 1.0. The Company had $5,388 outstanding under letters of credit as of June 30, 2007 and December 30, 2006.

During the first six months of 2007, the Company did not borrow under its revolving credit facility. As of June 30, 2007, there was no outstanding balance on the revolving facility.

On July 27, 2005 the Company entered into a $50,000 credit agreement (“$50,000 credit agreement”), which was subsequently amended on December 20, 2005 and again on July 31, 2006 to reflect substantially

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED
INTERIM FINANCIAL STATEMENTS (Continued)
(dollars in thousands, except per share amounts)

the same modifications made to the covenants in the $660,000 and $428,000 credit agreements, respectively. On June 15, 2007, the Company executed a third amendment to the $50,000 credit agreement to extend the maturity date and reduce the interest rate. The $50,000 credit agreement provides for a $50,000 term loan facility which matures on June 22, 2010. Prior to the amendment, the interest rate applicable to term loans under the credit agreement was, at the Company’s option, equal to either the base rate (which was the higher of the prime rate or the federal funds rate plus 0.50%) or the LIBOR rate plus 0.75%. Between June 15, 2007 through June 21, 2008, the interest rates applicable to term loans under the credit agreement was, at the Company’s option, equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) minus 2.25% or the LIBOR rate plus 0.50%. Commencing June 22, 2008 through June 22, 2010, the applicable interest rates are equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) or the adjusted LIBOR rate plus an interest rate margin based on the Company’s leverage ratio. The $50,000 credit agreement includes certain customary representations and warranties, negative and affirmative covenants and events of default. As of June 30, 2007, the entire balance of the $50,000 credit agreement was outstanding and classified as long-term debt.

On June 12, 2006, the Company issued $300,000 aggregate principal amount of convertible senior notes (“the 2013 Notes”) in a private placement with net proceeds to the Company of approximately $294,000. On June 20, 2006, the initial purchasers associated with this convertible debt offering exercised an option to purchase an additional $50,000 of the 2013 Notes for additional net proceeds to the Company of approximately $49,000. The 2013 Notes bear interest at 2.25% per annum, payable semi-annually, and mature on June 15, 2013. The 2013 Notes are convertible into cash and shares of the Company’s common stock (or, at the Company’s election, cash in lieu of some or all of such common stock), if any, based on an initial conversion rate, subject to adjustment, of 20.4337 shares of the Company’s common stock per $1,000 principal amount of notes (which represents an initial conversion price of $48.94 per share), only in the following circumstances and to the following extent: (i) during any fiscal quarter beginning after July 1, 2006 (and only during such fiscal quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is more than 130% of the conversion price on the last day of such preceding fiscal quarter; (ii) during the five business-day period after any five consecutive trading-day period, or the measurement period, in which the trading price per note for each day of that measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such day; (iii) upon the occurrence of specified corporate transactions, as described in the indenture for the 2013 Notes; and (iv) at the option of the holder at any time beginning on the date that is two months prior to the stated maturity date and ending on the close of business on the second trading-day immediately preceding the maturity date. Upon conversion, the Company will pay cash and shares of its common stock (or, at its election, cash in lieu of some or all of such common stock), if any. As of June 30, 2007, no conversion triggers were met. If the Company undergoes a fundamental change as described in the indenture for the 2013 Notes, holders will have the option to require the Company to purchase all or any portion of their notes for cash at a price equal to 100% of the principal amount of the notes to be purchased plus any accrued and unpaid interest, including any additional interest to, but excluding, the purchase date. The related debt issuance costs of $7,000 were deferred and are being amortized on a straight-line basis over a seven-year term.

Concurrently with the sale of the 2013 Notes, the Company entered into convertible note hedge transactions with respect to its obligation to deliver common stock under the notes. The convertible note hedges give the Company the right to receive, for no additional consideration, the number of shares of common stock that it is obligated to deliver upon conversion of the notes (subject to anti-dilution adjustments substantially identical to those in the 2013 Notes), and expire on June 15, 2013. The aggregate cost of these convertible note hedges was $98,293.

Separately and concurrently with the pricing of the 2013 Notes, the Company issued warrants for approximately 7.2 million shares of its common stock. The warrants give the holders the right to receive, for no additional consideration, cash or shares (at the option of the Company) with a value equal to the appreciation in the price of the Company’s shares above $59.925, and expire between September 13, 2013 and January 22, 2014 over 90 equal increments. The total proceeds from the issuance of the warrants was $65,423.

In accordance with Emerging Issues Task Force Issue (“EITF”) No. 00-19, “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock” (“EITF No. 00-19”), SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” and SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity,” the Company recorded both the purchase of the convertible note hedges and the sale of the warrants as adjustments to additional paid in capital, and will not recognize subsequent changes in fair value of the agreement. At June 30, 2007, the fair value of the outstanding 2013 Notes was approximately $421,750, based on their quoted market value.

9. Shareholders’ Equity

Earnings (Loss) per Share

Basic earnings per share for the three and six months ended June 30, 2007 and July 1, 2006 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. Diluted earnings per share was computed upon the weighted average number of common shares outstanding in the three months ended June 30, 2007 and July 1, 2006 and the six months ended June 30, 2007 and July 1, 2006 and dilutive common stock equivalents outstanding. Potential common shares outstanding principally include stock options under our stock option plans, warrants and the assumed conversion of our 2013 Notes.

Options to purchase 1,439,767 and 2,403,536 shares were outstanding in each of the three respective months ended June 30, 2007 and July 1, 2006, but were not included in computing diluted earnings per share because their inclusion would have been anti-dilutive. Options to purchase 2,174,418 and 1,479,150 shares were outstanding in each of the respective six months ended June 30, 2007 and July 1, 2006, but were not included in computing diluted earnings per share because their inclusion would have been anti-dilutive.

Basic weighted average shares outstanding for the three and six months ended June 30, 2007 and July 1, 2006 excluded the weighted average impact of 1,066,410 and 393,840 shares, respectively, of non-vested fixed restricted stock awards.

Treasury Shares

On July 27, 2005, the Board of Directors authorized a share repurchase program to acquire up to $50,000 of common stock. On October 26, 2005, the Board of Directors authorized increasing the share repurchase program by $50,000 to a total of $100,000. On May 9, 2006, the Board of Directors authorized an additional increase of the Company’s share repurchase program by $200,000 to acquire up to a total of $300,000 of common stock. On August 1, 2007, the Board of Directors authorized an additional increase of

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED
INTERIM FINANCIAL STATEMENTS (Continued)
(dollars in thousands, except per share amounts)

the Company’s share repurchase program by $100,000. The program does not have a fixed expiration date. In order to facilitate these share repurchases, the Company entered into Rule 10b5-1 Purchase Plans.

As of June 30, 2007, approximately $28,563 remained authorized for share repurchases prior to the new $100,000 authorization.

Share repurchases during the three and six months ended June 30, 2007 and July 1, 2006 were as follows:

	Three Months Ended				Six Months Ended
	June 30, 2007		July 1, 2006		June 30, 2007		July 1, 2006
Number of shares of common stock repurchased	48,000		3,921,300		143,200		4,168,200
Total cost of repurchase	$	2,538	$	157,458	$	6,748	$	168,886

Additionally, the Company’s 2000 Incentive Plan and 2007 Incentive Plan permits the netting of common stock upon vesting of restricted stock awards in order to satisfy individual tax withholding requirements. During the six months ended June 30, 2007 and July 1, 2006, the Company acquired 47,331 shares for $2,227 and 52,020 shares for $2,539, respectively, as a result of such withholdings. During the three months ended June 30, 2007 and July 1,2006, the Company acquired 2,991 shares for $143 and 4,319 shares for $202, respectively.

The timing and amount of any future repurchases will depend on market conditions and corporate considerations.

Warrants

As part of the recapitalization of the Company in 1999, the Company issued 150,000 units, each comprised of a $1,000 senior subordinated note and a warrant to purchase 7.6 shares of common stock of the Company for total proceeds of $150,000. The Company allocated the $150,000 offering proceeds between the senior subordinated notes ($147,872) and the warrants ($2,128), based upon the estimated fair value. The portion of the proceeds allocated to the warrants is reflected as capital in excess of par in the accompanying consolidated financial statements. Each warrant entitles the holder, subject to certain conditions, to purchase 7.6 shares of common stock of the Company at an exercise price of $5.19 per share of common stock, subject to adjustment under some circumstances. Upon exercise, the holders of warrants would be entitled to purchase 149,910 shares of common stock of the Company as of June 30, 2007. The warrants expire on October 1, 2009.

10. Income Taxes

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

	Three Months Ended						Six Months Ended
	June 30, 2007			July 1, 2006			June 30, 2007			July 1, 2006
Income before income taxes and minority interest	$	53,061		$	43,305		$	105,852		$	84,033
Effective tax rate	28.5		%	22.8		%	28.7		%	25.8		%
Provision for income tax	$	15,101		$	9,870		$	30,411		$	21,681

The Company’s overall effective tax rate was 28.5% in the second quarter of 2007. The increase from the 22.8% effective tax rate in the second quarter of 2006 is primarily due to the recording of a favorable discrete tax event related to Canadian federal tax rate reduction during the second quarter of 2006.

The Company adopted FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN48”), an interpretation of FASB Statement No. 109 (“SFAS 109”) on December 31, 2006. As a result of the implementation of FIN48, the Company recognized no adjustment in the liability for unrecognized income tax benefits. The total amount of unrecognized tax benefits as of the date of adoption was $17,514. At June 30, 2007 the amount recorded for income tax uncertainties was $20,236. The increase from the date of adoption is primarily due to the continuing evaluation of uncertain tax positions conducted in the current period. The amount of unrecognized tax benefits that, if recognized, would favorably impact the effective tax rate was $8,260 at the date of adoption and $10,671 as of June 30, 2007.

The Company continues to recognize interest and penalties related to uncertain tax positions in income tax expense. The total amount of accrued interest relating to uncertain tax positions as of December 31, 2006 and June 30, 2007 was $617 and $1,163, respectively. The Company has not recorded a provision for penalties associated with uncertain tax positions.

The Company conducts business globally and, as a result, the Company and its subsidiaries file income tax returns in the U.S. and foreign jurisdictions. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world, including but not limited to such major jurisdictions as Canada, the United Kingdom and the United States. With few exceptions the Company is no longer subject to U.S. and international income tax examinations for years before 2002.

The Company and certain of its subsidiaries are currently under audit by Canada Revenue Agency and the Internal Revenue Service in the United States. In regards to the Internal Revenue Service examinations of the 2004 tax returns of the Company and an acquired subsidiary, the Company filed its formal protests of certain proposed income tax adjustments with the Appeals Division on July 2, 2007. The Company does not believe that the ultimate settlement of these proposed adjustments will have a material impact to the financial statements. It is likely that the examination phase of the Canadian audit may conclude in 2007. The Company believes it has appropriately provided for all uncertain tax positions.

(dollars in thousands, except per share amounts)

During the period ended June 30, 2007, the Company settled audits with HM Revenue and Customs in the United Kingdom. The settlements had no significant impact to the uncertain tax positions or effective tax rate.

Due to the extensive protocol involved in finalizing audits with the relevant tax authorities including potential formal legal proceedings, it is not possible to estimate the impact of any amount of change to previously recorded uncertain tax positions.

12. Stock-Based Compensation Plans

Effective January 1, 2006, the Company adopted, on a modified prospective basis, the provisions of SFAS No. 123(R), “Share-Based Payment (Revised 2004),” (“SFAS No. 123(R)”) and related guidance which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including employee stock options and restricted stock awards

based on estimated fair values. Accordingly, stock-based compensation cost is measured at grant date, based on the fair value of the award and is recognized as expense on a straight-line basis over the requisite service period.

The estimated fair value of the Company’s stock-based awards, less expected forfeitures, is amortized over the awards’ vesting period on a straight-line basis. The effect of recording stock-based compensation for the three and six months ended June 30, 2007 and July 1, 2006 was as follows:

	Three Months Ended								Six Months Ended

The Company estimates the fair value of stock options using the Black-Scholes valuation model. Key inputs and assumptions used to estimate the fair value of stock options include the exercise price of the award, the expected option term, the risk-free interest rate over the option’s expected term, the expected annual dividend yield and the expected stock price volatility. The expected stock price volatility assumption was determined using the historical volatility of the Company’s common stock over the expected life of the option. The risk-free interest rate was based on the market yield for the five year U.S. Treasury security. The expected life of options was determined using historical option exercise activity. Management believes that the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in calculating the fair values of the Company’s stock options granted. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards.

Performance-Based Stock Award Program

During the first quarter of 2007, the Company adopted a new performance-based stock award program for its executives. Compensation expense associated with awards made under this new program of $792 and $1,095 has been recorded during the three and six months ended June 30, 2007, respectively. Payout of this award is contingent upon achievement of individualized stretch goals during 2007 as determined by the Company’s Board of Directors.

13. 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.

15. Recently Issued Accounting Standards

The FASB has issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of SFAS No. 109” (“FIN 48”), which clarifies the accounting for uncertainty in income taxes. Prior to the effective date of FIN 48, the accounting for uncertainty in income taxes was subject to significant and varied interpretations that have resulted in diverse and inconsistent accounting practices and measurements. Addressing such diversity, FIN 48 prescribes a consistent recognition threshold and measurement attribute, as well as clear criteria for subsequently recognizing, derecognizing and measuring changes in such tax positions for financial statement purposes. FIN 48 also requires expanded disclosure with respect to the uncertainty in income taxes. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company adopted the provisions of FIN 48 effective December 31, 2006 which did not have a significant impact on its consolidated financial results. Refer to Note 10.

The Company adopted the recognition and disclosure requirements of SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans—an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”) as of December 30, 2006. This Standard includes two phases of implementation. The second phase of SFAS 158 requires that the valuation date of plan accounts be as of the end of the fiscal year, with that change required to be implemented by fiscal years ending after December 15, 2008. The Company will change the valuation date relating to its foreign plans which will not have a material impact on the Company’s consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (“SFAS 157”). SFAS 157 establishes a single authoritative definition of fair value, sets out framework for measuring fair value and expands on required disclosures about fair value measurements. SFAS 157 is effective for the Company on January 1, 2008 and will be applied prospectively. The provisions of SFAS 157 are not expected to have a material impact on the Company’s consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115” (“SFAS 159”). This Standard allows companies to elect to follow fair value accounting for certain financial assets and liabilities in an effort to mitigate volatility in earnings without having to apply complex hedge accounting provisions. SFAS 159 is applicable only to certain financial instruments and is effective for fiscal years beginning after November 15, 2007. The provisions of SFAS 159 are not expected to have a material impact on the Company’s consolidated financial statements.

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

The following discussion should be read in conjunction with our condensed consolidated financial statements and the related notes.

Overview

Continuing Operations

We are a leading global provider of solutions that advance the drug discovery and development process, including research models and associated services and outsourced preclinical services, which include Phase I clinical services. We partner with global pharmaceutical companies, a wide range of biotechnology companies, as well as government agencies, leading hospitals and academic institutions throughout the world in order to bring drugs to market faster and more efficiently. Our broad portfolio of products and services enables our customers to reduce costs, increase speed and enhance their productivity and effectiveness in drug discovery and development. We have been in business for 60 years.

For the second quarter of 2007, sales growth was driven by spending by major pharmaceuticals, biotechnology companies and academic institutions on our global products and services, which aid in their development of new drugs and products. Future drivers for our business as a whole are primarily expected to emerge from our customers’ continued growing demand for drug discovery and development services, including increased strategic focus on outsourcing.

We expect our continuing capacity expansion program to position us to take advantage of these long-term opportunities. For instance, in order to meet demand for our preclinical services, we opened our new preclinical site in Massachusetts, we plan to open our new preclinical site in Nevada in 2008 and plan to construct additional preclinical capacity in Scotland, Canada, Ohio and China. We are particularly enthusiastic to commence construction of our new China facility, which we hope will enable us to be the partner of choice for our global pharmaceutical and biotechnology customers as they establish and expand research and development activities in the rapidly growing Chinese market. Furthermore, the opening of our California Research Models and Services (“RMS”) expansion and the ground breaking of our facility in Maryland, which will support the National Cancer Institute (“NCI”) contract, reflect our commitment to address demand for our RMS products and services. Our capital expenditures of $87.3 million during the six months ended June 30, 2007, and our planned capital expenditures in the range of $200 million to $225 million for total 2007, reflect our ongoing commitment to our capital expansion program. In addition to internally generated organic growth, our business strategy includes strategic “bolt-on” acquisitions that complement our business, increase the rate of our growth or geographically expand our existing services.

Total net sales during the second quarter of 2007 were $307.4 million, an increase of 14.8% over the same period last year. The sales increase was due primarily to increased customer demand and higher pricing, with strong sales in both Preclinical Services (“PCS”) and RMS. The effect of foreign currency translation added 2.1% to sales growth. Our gross margin decreased to 39.3% of net sales for the second quarter of 2007, compared to 40.0% of net sales for the second quarter of 2006, due mainly to start-up and transition cost for our PCS Massachusetts facilities, partially offset by favorable results in our other large PCS locations and in RMS.

Our operating income for the second quarter of 2007 was $56.7 million compared to $47.7 million for the second quarter of 2006, an increase of 18.9%. The operating margin was 18.5% for the second quarter of 2007 compared to 17.8% for the prior year, primarily due to improved margins in the RMS businesses and lower amortization expense partially offset by higher costs in the PCS segment due to Massachusetts start-up and transition costs. Net income from continuing operations was $37.8 million for the second quarter of 2007 compared to $32.8 million for the second quarter of 2006. Diluted earnings per share from continuing operations for the second quarter of 2007 were $0.55 compared to $0.46 for the second quarter of 2006.

Total net sales during the six months ended June 30, 2007 were $598.6 million, an increase of 14.7% over the same period last year. The sales increase was due primarily to increased customer demand and higher pricing, with strong sales in both PCS and RMS. The effect of foreign currency translation added 2.4% to sales growth. Our gross margin increased to 39.5% of net sales for the six months ended June 30, 2007, compared to 38.8% of net sales for the first six months of 2006, due primarily to improved capacity utilization in the PCS and RMS segments, partially offset by start-up and transition costs for our PCS Massachusetts facilities.

Our operating income for the six months ended June 30, 2007 was $111.4 million compared to $91.4 million for the six months ended July 1, 2006, an increase of 21.9%. The operating margin was 18.6% for the six months ended June 30, 2007 compared to 17.5% for the prior year, with improved margins in both the PCS and RMS businesses. Net income from continuing operations was $75.1 million for the six months ended June 30, 2007 compared to $61.3 million for the six months ended July 1, 2006. Diluted earnings per share from continuing operations for the first six months of 2007 were $1.10 compared to $0.84 for the first six months of 2006.

We report two segments: RMS and PCS, which reflect the manner in which our operating units are managed. Our PCS segment includes our Phase I clinical services business, which we view as an integral strategic component of our service offerings because it enables us to support our customers’ preclinical efforts through early-stage clinical trials.

Our RMS segment, which represented 46.8% of net sales in the second quarter of 2007, includes research models, transgenic services, laboratory services, discovery services, consulting and staffing services, vaccine support and in vitro technology (primarily endotoxin testing). Net sales for this segment increased 9.9% for the second quarter of 2007 compared to the second quarter of 2006, due to increased transgenic sales, strong in vitro sales and increased small model sales in the United States and Europe. Favorable foreign currency translation increased the net sales gain by 1.8%. We experienced increases in both the RMS gross margin and operating margin compared to last year (to 43.9% from 42.4% and to 31.5% from 29.1%, respectively), mainly due to the impact of higher sales. Our Northern California production facility expansion is intended to meet our West Coast customers’ increased need for models and discovery services for their drug discovery and development efforts. We began production in approximately one half of this addition in the second quarter of 2007.

Sales on a year to date basis for our RMS business segment increased 10.4% compared to the first six months of 2006, due to increased large model shipments, increased transgenic sales, strong in vitro sales and increased small model sales in the United States and Europe, partially offset by lower small model growth in Japan and lower vaccine sales. Operating income on a year to date basis was $92.3 million compared to $78.5 million, an increase of $13.8 million, or 17.6%, from the same period last year. Operating income for the first six months as a percent of net sales increased to 32.2% compared to 30.2% for the same period last year.

Our PCS segment, which represented 53.2% of net sales in the second quarter of 2007, includes services required to take a drug through the development process including discovery support, toxicology, pathology, biopharmaceutical, bioanalysis, pharmacokinetics and drug metabolism services, as well as, Phase I clinical trials. Sales for this segment for the second quarter of 2007 increased 19.4% over the second quarter of 2006. Sales were driven by continuing strong demand for general and specialty toxicology studies by pharmaceutical and biotechnology customers and the addition of the Northwest Kinetics Phase I clinical services business. Favorable foreign currency increased sales growth by 2.3%. We experienced a decrease in the PCS gross margin for the second quarter of 2007 from 37.7% in 2006 to 35.4% due mainly to start-up and transition costs related to our PCS Massachusetts facilities, partially offset by favorable results for our other large PCS locations and RMS. Operating income increased to 16.8% of net sales for the second quarter of 2007, compared to 16.4% for 2006 due to lower amortization expense offset by the

lower gross margin. We expect to see increasing levels of customer demand in certain of our development services businesses, particularly large model, reproductive and inhalation toxicology. We continue to focus on meeting the growing demand for our preclinical services and increased outsourcing trends through our capital expansion program.

Sales on a year to date basis for our Preclinical Services segment increased 18.9% over the same period last year. Operating income for the first six months increased to 16.3% of net sales, compared to 13.9% for the first six months of 2006, due to lower amortization expense and increased gross margin.

Discontinued Operations

Our former Phase II-IV Clinical Services and our Interventional and Surgical Services (“ISS”) businesses are reported as discontinued operations. Our historical information has been reclassified to reflect discontinued operations.

The net loss from discontinued operations for the first half of 2007 was $0.3 million, which relates to results from our ISS business.

During fiscal 2006, we initiated actions to sell and sold Phase II-IV of our clinical business. Accordingly, management performed appropriate goodwill impairment and asset impairment tests for the clinical business segment. As a result, we recorded charges of $133.1 million to write down the value of the goodwill and impaired assets associated with the clinical business in the first six months of 2006. Additionally, we made a decision to close our ISS business, which was formerly included in the PCS segment, and recorded an impairment charge of $1.1 million associated with this business.

Three Months Ended June 30, 2007 Compared to Three Months Ended July 1, 2006

Net Sales. Net sales for the three months ended June 30, 2007 were $307.4 million, an increase of $39.5 million, or 14.8%, from $267.9 million for the three months ended July 1, 2006.

Research Models and Services. For the three months ended June 30, 2007, net sales for our RMS segment increased to $143.8 million from $130.8 million for the three months ended July 1, 2006, an increase of 9.9%. Favorable foreign currency translation increased sales growth by approximately 1.8%. RMS sales increased due to pricing and unit volume increases in both models and services, driven by increases in basic research and biotechnology spending.

Preclinical Services. For the three months ended June 30, 2007, net sales for our PCS segment were $163.6 million, an increase of $26.6 million, or 19.4%, compared to $137.0 million for the three months ended July 1, 2006. The increase was primarily due to the increased customer demand for toxicology and other specialty preclinical services, reflecting increased customer outsourcing and the addition of the Northwest Kinetics Phase I clinical service business. Favorable foreign currency increased sales growth by 2.3%.

Cost of Products Sold and Services Provided. Cost of products sold and services provided for the three months ended June 30, 2007 was $186.5 million, an increase of $25.8 million, or 16.0%, from $160.7 million for the three months ended July 1, 2006. Cost of products sold and services provided for the three months ended June 30, 2007 was 60.7% of net sales, compared to 60.0% for the three months ended July 1, 2006.

Research Models and Services. Cost of products sold and services provided for RMS for the three months ended June 30, 2007 was $80.7 million, an increase of $5.4 million, or 7.1%, compared to $75.3 million for the three months ended July 1, 2006. Cost of products sold and services provided decreased as a percent of net sales to 56.1% for the three months ended June 30, 2007, compared to the three months ended July 1, 2006 at 57.6% of net sales. Increased sales during the quarter resulted in greater facility utilization and greater economics of scale.

Preclinical Services. Cost of products sold and services provided for the PCS segment for the three months ended June 30, 2007 was $105.8 million, an increase of $20.4 million, or 23.9%, compared to $85.4 million for the three months ended July 1, 2006. Cost of products sold and services provided as a percentage of net sales was 64.6% for the three months ended June 30, 2007, compared to 62.3% for the three months ended July 1, 2006. The increase in cost of products sold and services provided as a percentage of net sales was primarily due to start-up and transition cost for our PCS Massachusetts facilities, partially offset by favorable results for our other PCS toxicology locations.

Selling, General and Administrative Expenses. Selling, general and administrative expenses for the three months ended June 30, 2007 were $56.1 million, an increase of $6.1 million, or 12.1%, from $50.0 million for the three months ended July 1, 2006. Selling, general and administrative expenses for the three months ended June 30, 2007 were 18.2% of net sales compared to 18.7% of net sales for the three months ended July 1, 2006. The decrease as a percentage of sales was due primarily to lower selling, general and administrative expenses as a percentage of sales in both RMS and PCS, partially offset by increases in unallocated corporate overhead.

Research Models and Services. Selling, general and administrative expenses for RMS for the three months ended June 30, 2007 were $17.5 million, an increase of $0.1 million, or 0.5%, compared to $17.4 million for the three months ended July 1, 2006. Selling, general and administrative expenses decreased as a percentage of sales to 12.1% for the three months ended June 30, 2007 from 13.3% for the three months ended July 1, 2006 due mainly to greater economies of scale.

Preclinical Services. Selling, general and administrative expenses for the PCS segment for the three months ended June 30, 2007 were $22.6 million, an increase of $2.8 million, or 14.3%, compared to $19.8 million for the three months ended July 1, 2006. Selling, general and administrative expenses for the three months ended June 30, 2007 decreased to 13.8% of net sales, compared to 14.5% of net sales for the three months ended July 1, 2006.

Unallocated Corporate Overhead. Unallocated corporate overhead, which consists of various corporate expenses, including those associated with pension, executive salaries, stock-based compensation and departments such as corporate accounting, information technology, human resources, and tax, was $16.0 million for the three months ended June 30, 2007, compared to $12.8 million for the three months ended July 1, 2006. The increase in unallocated corporate overhead during the second quarter of 2007 was due primarily to increased stock compensation, higher information technology costs and increased corporate business development costs.

Amortization of Other Intangibles. Amortization of other intangibles for the three months ended June 30, 2007 was $8.1 million, a decrease of $1.3 million, from $9.4 million for the three months ended July 1, 2006.

Preclinical Services. For the three months ended June 30, 2007, amortization of other intangibles for our PCS segment was $7.8 million, compared to $9.3 million for the three months ended July 1, 2006. The decrease was primarily due to reduced amortization related to the acquisition of Inveresk.

Operating Income. Operating income for the three months ended June 30, 2007 was $56.7 million, an increase of $9.0 million, or 18.9%, from $47.7 million for the three months ended July 1, 2006. Operating income for the three months ended June 30, 2007 was 18.5% of net sales, compared to 17.8% of net sales for the three months ended July 1, 2006.

Operating income as a percentage of net sales for the three months ended June 30, 2007 was 31.5%, compared to 29.1% for the three months ended July 1, 2006. The increase

in operating income as a percentage of sales was primarily due to increased utilization as a result of higher sales volume.

Preclinical Services. For the three months ended June 30, 2007, operating income for our PCS segment was $27.4 million, an increase of $4.9 million, or 21.7%, from $22.5 million for the three months ended July 1, 2006. Operating income as a percentage of net sales increased to 16.8%, compared to 16.4% of net sales for the three months ended July 1, 2006. The increase in operating income as a percentage of net sales was primarily due to lower amortization costs and favorable results for most of our PCS locations, partially offset by the gross margin impact of the start-up and transition costs for our PCS Massachusetts facilities.

Interest Expense. Interest expense for the three months ended June 30, 2007 was $4.9 million, compared to $4.6 million for the three months ended July 1, 2006.

Interest Income. Interest income during the second quarter of 2007 was $2.3 million compared to $1.0 million during the second quarter of 2006 due to increased funds available for investment.

Income Taxes. Income tax expense for the three months ended June 30, 2007 was $15.1 million, an increase of $5.2 million compared to $9.9 million for the three months ended July 1, 2006. The increase was primarily due to the recording of a favorable discrete tax event related to the Canadian federal tax rate reduction during the second quarter of last year.

Income from Continuing Operations. Net income from continuing operations in the second quarter of 2007 was $37.8 million, compared to $32.8 million in the same period last year. Diluted earnings per share from continuing operations in the second quarter of 2007 were $0.55, compared to $0.46 in the same period last year.

Income (Loss) from Discontinued Operations. For the three months ended June 30, 2007, income from discontinued operations was $0.1 million, related to our ISS business, compared to a loss of $7.0 million in the second quarter of 2006. In the second quarter of 2006, taking into account the planned divestiture of the Phase II-IV Clinical Services business and the closure of the ISS business, the Company recorded $5.0 million of impairment charges.

Net Income. Net income for the three months ended June 30, 2007 was $38.0 million, an increase of $12.2 million from $25.8 million for the three months ended July 1, 2006.

Six Months Ended June 30, 2007 Compared to Six Months Ended July 1, 2006

Net Sales. Net sales for the six months ended June 30, 2007 were $598.6 million, an increase of $76.6 million, or 14.7%, from $522.0 million for the six months ended July 1, 2006.

Research Models and Services. For the six months ended June 30, 2007, net sales for our RMS segment were $286.9 million, an increase of $27.1 million from $259.8 million for the six months ended July 1, 2006, due to strong demand for research models from large pharmaceutical customers in North America and Europe, increased demand for transgenic services and higher sales of in vitro products, partially offset by lower small model growth in Europe and Japan. Sales of large models increased as shipments which had been delayed from the fourth quarter of 2006 due to an extended quarantine were released. Favorable foreign currency translation increased sales growth by approximately 2.2%. RMS sales increased due to pricing and unit volume increases in both models, including large models, and services. The RMS sales growth was driven by increases in basic research and biotechnology spending, which drove greater demand for our products and services.

Preclinical Services. For the six months ended June 30, 2007, net sales for our PCS segment were $311.7 million, an increase of $49.5 million, or 18.9%, compared to $262.2 million for the six months ended July 1, 2006. The increase in PCS sales was primarily due to the increased customer demand for toxicology

and other specialty preclinical services, reflecting increased customer outsourcing and the addition of Northwest Kinetics Phase I clinical service business. Favorable foreign currency increased sales growth by 2.6%.

Cost of Products Sold and Services Provided. Cost of products sold and services provided for the six months ended June 30, 2007 was $362.1 million, an increase of $42.7 million, or 13.4%, from $319.4 million for the six months ended July 1, 2006. Cost of products sold and services provided for the six months ended June 30, 2007 was 60.5% of net sales, compared to 61.2% for the six months ended July 1, 2006, due to greater utilization which resulted from the increased sales.

Cost of products sold and services provided for RMS for the six months ended June 30, 2007 was $160.1 million, an increase of $11.7 million, or 7.9%, compared to $148.4 million for the six months ended July 1, 2006. Cost of products sold and services provided as a percentage of net sales for the six months ended June 30, 2007 was 55.8% compared to the six months ended July 1, 2006 at 57.1% of net sales. The greater facility utilization was the result of the increased sales during the quarter.

Preclinical Services. Cost of products sold and services provided for the PCS segment for the six months ended June 30, 2007 was $202.0 million, an increase of $31.1 million, or 18.2%, compared to $170.9 million for the six months ended July 1, 2006. Cost of products sold and services provided as a percentage of net sales was 64.8% for the six months ended June 30, 2007, compared to 65.2% for the six months ended July 1, 2006. The decrease in cost of products sold and services provided as a percentage of net sales was primarily due to improved capacity utilization resulting from the increased sales of services, partially offset by the start-up and transition costs of PCS Massachusetts facilities.

Selling, General and Administrative Expenses. Selling, general and administrative expenses for the six months ended June 30, 2007 were $109.1 million, an increase of $16.3 million, or 17.6%, from $92.8 million for the six months ended July 1, 2006. Selling, general and administrative expenses for the six months ended June 30, 2007 were 18.2% of net sales compared to 17.8% of net sales for the six months ended July 1, 2006. The increase as a percentage of sales was due primarily to increases in unallocated corporate overhead.

Research Models and Services. Selling, general and administrative expenses for RMS for the six months ended June 30, 2007 were $33.7 million, an increase of $1.0 million, or 3.2%, compared to $32.7 million for the six months ended July 1, 2006. Selling, general and administrative expenses decreased as a percentage of sales to 11.8% for the six months ended June 30, 2007 from 12.6% for the six months ended July 1, 2006 due mainly to greater economies of scale.

Net Income (Loss). Net income for the six months ended June 30, 2007 was $74.7 million compared to a net loss for the six months ended July 1, 2006 of $74.4 million.

Liquidity and Capital Resources

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

Our principal sources of liquidity have been our cash flow from operations, the convertible debt offering and our revolving line of credit arrangements.

On June 12, 2006, we issued $350.0 million aggregate principal amount of convertible senior subordinated notes (“the 2013 Notes”) in a private placement with net proceeds to the Company of $343.0 million. The 2013 Notes bear interest at 2.25% per annum, payable semi-annually, and mature on June 15, 2013. The 2013 Notes are convertible into cash and shares of common stock (or, at the Company’s election, cash in lieu of some or all of such common stock) based on an initial conversion rate, subject to adjustment, of 20.4337 shares of common stock per $1,000 principal amount of notes (which represents an initial conversion price of $48.94 per share).

Concurrently with the sale of the 2013 Notes, we entered into convertible note hedge transactions with respect to our obligation to deliver common stock under the 2013 Notes. The convertible note hedges give us the right to receive, for no additional consideration, the numbers of shares of common stock that we are obligated to deliver upon conversion of the 2013 Notes (subject to antidilution adjustments substantially identical to those in the 2013 Notes), and expire on June 15, 2013. The aggregate cost of these convertible note hedges was $98.3 million.

Separately and concurrently with the pricing of the 2013 Notes, we issued warrants for approximately 7.2 million shares of our common stock. The warrants give the holders the right to receive, for no additional consideration, cash or shares (at our option) with a value equal to the appreciation in the price of our shares above $59.925, and expire between September 13, 2013 and January 22, 2014 over 90 equal increments. The total proceeds from the issuance of the warrants were $65.4 million.

From our economic perspective, the cumulative impact of the purchase of the convertible note hedges and the sale of the warrants increases the effective conversion price of the 2013 Notes from $48.94 to $59.25 per share.

On July 31, 2006, we amended and restated our $660.0 million credit agreement to reduce the current interest rate, modify certain restrictive covenants and extend the term. The amount of debt outstanding under the original $660.0 million credit agreement remained the same at the time of amendment. The now $428.0 million credit agreement provides for a $156 million U.S. term loan facility, a $200.0 million U.S. revolving facility, a C$57.8 million term loan facility and a C$12.0 million revolving facility for a Canadian subsidiary, and a GBP 6.0 million revolving facility for a U.K. subsidiary. The $156.0 million term loan facility matures in 20 quarterly installments with the last installment due June 30, 2011. The $200.0 million U.S. revolving facility matures on July 31, 2011 and requires no scheduled payment before that date. Under specified circumstances, the $200.0 million U.S. revolving facility may be increased by $100.0 million. The Canadian term loan is repayable in full by June 30, 2011 and requires no scheduled prepayment before that date. The Canadian and U.K. revolving facilities mature on July 31, 2011 and require no scheduled prepayment before that date. The interest rate applicable to the Canadian term loan and the Canadian and U.K. revolving loans under the credit agreement is the adjusted LIBOR rate in its relevant currency plus an interest rate margin based upon our leverage ratio. The interest rates applicable to term loans and revolving loans under the credit agreement are, at our option, equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) or the adjusted LIBOR rate plus an interest rate margin based upon our leverage ratio. Based on our leverage ratio, the margin range for LIBOR based loans is 0.625% to 0.875%. The interest rate margin was 0.75% as of June 30, 2007. We have pledged the stock of certain subsidiaries as well as certain U.S. assets as security for the $428.0 million credit agreement. The $428.0 million credit agreement includes certain customary representations and warranties, negative and affirmative covenants and events of default. We had $5.0 million outstanding under letters of credit as of June 30, 2007 and December 30, 2006.

During the first six months of 2007, we did not borrow under our revolving credit facility. As of June 30, 2007, there was no outstanding balance on the revolving facility.

On July 27, 2005, we entered into a $50 million credit agreement (“$50 million credit agreement”), which was subsequently amended on December 20, 2005 and again on July 31, 2006 to reflect substantially the same modifications made to the covenants in the $660 million and $428 million credit agreements, respectively. On June 15, 2007, we executed a third amendment to the $50 million credit agreement to extend the maturity date and reduce the interest rate. The $50 million credit agreement provides for a $50 million term loan facility which matures on June 22, 2010. Prior to the amendment, the interest rate applicable to term loans under the credit agreement was, at our option, equal to either the base rate (which was the higher of the prime rate or the federal funds rate plus 0.50%) or the LIBOR rate plus 0.75%. From June 15, 2007 through June 21, 2008, the interest rates applicable to term loans under the credit agreement was, at our option, equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) minus 2.25% or the LIBOR rate plus 0.50%. Commencing June 22, 2008 through June 22, 2010, the applicable interest rates are equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) or the adjusted LIBOR rate plus an interest rate margin based on our leverage ratio. The $50 million credit agreement includes certain customary representations and warranties, negative and affirmative covenants and events of default. As of June 30, 2007, the entire balance of the $50 million credit agreement was outstanding and classified as long-term debt.

In November 2006, we entered into a new Rule 10b5-1 Stock Purchase Plan with a third-party investment bank for the remaining shares authorized under our share repurchase program. As of June 30, 2007, approximately $28.6 million remained authorized for share repurchases. On August 1, 2007, the Board of Directors authorized an additional increase of our share repurchase program by $100 million. The timing and amount of future repurchases will depend on market conditions and corporate considerations.

Cash and cash equivalents totaled $162.1 million at June 30, 2007, compared to $175.4 million at December 30, 2006.

Net cash provided by operating activities for the six months ended June 30, 2007 and July 1, 2006 was $93.4 million and $60.2 million, respectively. The increase in cash provided by operations was primarily a result of increased earnings. Our days sales outstanding (“DSO”) of 40 days as of June 30, 2007 increased from 39 days at December 30, 2006 and 33 days at July 1, 2006. Our DSO includes deferred revenue as an offset to accounts receivable in the calculation.

Net cash used in investing activities for the six months ended June 30, 2007 and July 1, 2006 was $93.1 million and $90.4 million, respectively. For the six months ended June 30, 2007, we used $87.3 million for capital expenditures, compared to the six month period in 2006, during which we paid $56.8 million for capital expenditures. Year to date 2007, we made capital expenditures in RMS of $17.8 million and in PCS of $69.6 million, due mainly to the construction of our facilities in Nevada and Massachusetts. We anticipate that future capital expenditures will be funded by cash provided by operating activities. For fiscal 2007, we project capital expenditures to be approximately $200 - 225 million. For the six months ended June 30, 2007, purchases of marketable securities were $79.5 million, compared to $47.6 million in 2006.

Net cash used in financing activities for the six months ended June 30, 2007 was $15.1 million compared to net cash provided by financing activities of $114.1 million for the six months ended July 1, 2006. For the six months ended July 1, 2006, we had proceeds from long-term debt of $440.2 million due mainly to the sale of the 2013 Notes. Proceeds from exercises of employee stock options amounted to $30.6 million and $17.5 million for the six months ended June 30, 2007 and July 1, 2006, respectively. Year to date 2007 and 2006, we repaid $38.0 million and $132.6 million of debt, respectively.

New Accounting Pronouncements

The FASB has issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of SFAS No. 109” (“FIN 48”), which clarifies the accounting for uncertainty in income taxes. Prior to the effective date of FIN 48, the accounting for uncertainty in income taxes was subject to significant and varied interpretations that have resulted in diverse and inconsistent accounting practices and measurements. Addressing such diversity, FIN 48 prescribes a consistent recognition threshold and measurement attribute, as well as clear criteria for subsequently recognizing, derecognizing and measuring changes in such tax positions for financial statement purposes. FIN 48 also requires expanded disclosure with respect to the uncertainty in income taxes. FIN 48 is effective for fiscal years beginning after December 15, 2006. We adopted the provisions of FIN 48 effective December 31, 2006 which did not have a significant impact on its consolidated financial results. Refer to Note 10.

We adopted the recognition and disclosure requirements of SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans—an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”) as of December 30, 2006. This Standard includes two phases of implementation. The second phase of SFAS 158 requires that the valuation date of plan accounts be as of the end of the fiscal year, with that change required to be implemented by fiscal years ending after December 15, 2008. We will change the valuation date relating to our foreign plans which will not have a material impact on our consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157 establishes a single authoritative definition of fair value, sets out framework for measuring fair value and expands on required disclosures about fair value measurements. SFAS 157 is effective for us on January 1, 2008 and will be applied prospectively. The provisions of SFAS 157 are not expected to have a material impact on our consolidated financial statements.

Off-Balance Sheet Arrangements

The conversion features of our 2013 Notes are equity-linked derivatives. As such, we recognize these instruments as off-balance sheet arrangements. The conversion features associated with these notes would be accounted for as derivative instruments, except that they are indexed to our common stock and classified in stockholders’ equity. Therefore, these instruments meet the scope of exception of paragraph 11(a) of SFAS No. 133, “Accounting for Derivatives Instruments and Hedging Activities,” and are accordingly not accounted for as derivatives for purposes of SFAS No. 133.

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

Interest Rate Risk

The fair value of our marketable securities is subject to interest rate risk and will fall in value if market interest rates increase. If market rates were to increase immediately and uniformly by 100 basis points from levels at June 30, 2007, then the fair value of the portfolio would decline by approximately $0.2 million.

We have entered into two credit agreements, the $428 million credit agreement (prior to July 31, 2006, the $660 million credit agreement) and the $50 million credit agreement. Our primary interest rate exposure results from changes in LIBOR or the base rates which are used to determine the applicable interest rates under our term loans in the $428 million credit agreement and in the $50 million agreement and our revolving credit facilities. Our potential loss over one year that would result from a hypothetical, instantaneous and unfavorable change of 100 basis points in the interest rate would be approximately $4.1 million on a pre-tax basis. The book value of our debt approximates fair value.

We issued $350 million of the 2013 Notes in a private placement in the second quarter of 2006. The convertible senior debenture notes bear an interest rate of 2.25%. The fair market value of the outstanding notes was $421.8 million on June 30, 2007.

Foreign Currency Exchange Rate Risk

We operate on a global basis and have exposure to some foreign currency exchange rate fluctuations for our earnings and cash flows. This risk is mitigated by the fact that various foreign operations are principally conducted in their respective local currencies. A portion of our foreign operations’ revenue is denominated in U.S. dollars, with the costs accounted for in their local currencies. We attempt to minimize this exposure by using certain financial instruments, for purposes other than trading, in accordance with our overall risk management and our hedge policy. In accordance with our hedge policy, we designate such transactions as hedges as set forth in SFAS No. 133.

During 2007, we utilized foreign exchange contracts, principally to hedge the impact of currency fluctuations on customer transactions and certain balance sheet items. There were no contracts open as of June 30, 2007.

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

Based on their evaluation, required by paragraph (b) of Rules 13a-15 or 15d-15, promulgated by the Securities Exchange Act of 1934, 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 as of June 30, 2007 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 an issuer in the reports that it files or submits under the Act is accumulated and communicated to the issuer’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 recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurances of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures. We continually are in the process of further reviewing and documenting our disclosure controls and procedures, and our internal control over financial reporting, and accordingly may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

(b) Changes in Internal Controls

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 30, 2007 that materially affected, or were reasonably likely to materially affect, the Company’s internal control over financial reporting.

The program does not have a fixed expiration date. On August 1, 2007, the Board of Directors authorized an additional increase of the Company’s share repurchase program by $100.0 million.
