Special Note on Factors Affecting Future Results
This Quarterly Report on Form 10-Q contains forward-looking statements regarding future events and the future results of Charles River Laboratories International, Inc. that are based on our current expectations, estimates, forecasts and projections about the industries in which we operate and the beliefs and assumptions of our management. Words such as “expect,” “anticipate,” “target,” “goal,” “project,” “intend,” “plan,” “believe,” “seek,” “estimate,” “will,” “likely,” “may,” “designed,” “would,” “future,” “can,” “could,” and other similar expressions thatwhich are predictions of, or indicate future events and trends or which do not relate to historical matters, are intended to identify such forward-looking statements. These statements are based on our current expectations and beliefs and involve a number of risks, uncertainties and assumptions that are difficult to predict. These statements also include statements regarding risks and uncertainties associated with the unauthorized access into our information systems reported on April 30, 2019, including the timing and effectiveness of adding enforced security features and monitoring procedures, and the potential revenue and financial impact related to the incident.
For example, we may use forward-looking statements when addressing topics such as: goodwill and asset impairments still under review; future demand for drug discovery and development products and services, including the outsourcing of these services; our expectations regarding stock repurchases, including the number of shares to be repurchased, expected timing and duration, the amount of capital that may be expended and the treatment of repurchased shares; present spending trends and other cost reduction activities by our clients; future actions by our management; the outcome of contingencies; changes in our business strategy, business practices and methods of generating revenue; the development and performance of our services and products; market and industry conditions, including competitive and pricing trends; our strategic relationships with leading pharmaceutical and biotechnology companies, and venture capital investments, and opportunities for future similar arrangements; our cost structure; the impact of acquisitions;acquisitions, including Citoxlab; our expectations with respect to revenue growth and operating synergies (including the impact of specific actions intended to cause related improvements); the impact of specific actions intended to improve overall operating efficiencies and profitability (and our ability to accommodate future demand with our infrastructure), including gains and losses attributable to businesses we plan to close, consolidate, divest or divest (including our Maryland research model production site);repurpose; changes in our expectations regarding future stock option, restricted stock, performance share units, and other equity grants to employees and directors; expectations with respect to foreign currency exchange; assessing (or changing our assessment of) our tax positions for financial statement purposes; and our liquidity. In addition, these statements include the impact of economic and market conditions on us and our clients; the effects of our cost saving actions and the steps to optimize returns to shareholders on an effective and timely basis; and our ability to withstand the current market conditions.
You should not rely on forward-looking statements because they are predictions and are subject to risks, uncertainties, and assumptions that are difficult to predict. Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this document, or in the case of statements incorporated by reference, on the date of the document incorporated by reference.
Factors that might cause or contribute to such differences include, but are not limited to, those discussed in our Annual Report on Form 10-K for the year ended December 30, 2017,29, 2018, under the sections entitled “Our Strategy,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and in this Quarterly Report on Form 10-Q, under the sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors,” in our press releases, and other financial filings with the Securities and Exchange Commission. We have no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or risks. New information, future events, or risks may cause the forward-looking events we discuss in this report not to occur.

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


1. BASIS OF PRESENTATION
The accompanying condensed consolidated financial statements are unaudited and have been prepared by Charles River Laboratories International, Inc. (the Company) in accordance with accounting principles generally accepted in the United States (U.S. GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). The year-end condensed consolidated balance sheet data was derived from the Company’s audited consolidated financial statements, but does not include all disclosures required by U.S. GAAP. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for fiscal year 2017.2018. The unaudited condensed consolidated financial statements, in the opinion of management, reflect all normal and recurring adjustments necessary for a fair statement of the Company’s financial position and results of operations.
The Company has reclassified certain amounts in the unaudited condensed consolidated statements of income for prior periods to conform to the current year presentation. See “Newly Adopted Accounting Pronouncements” below for further discussion and impact on the condensed consolidated financial statements.
Use of Estimates
The preparation of unaudited condensed consolidated financial statements in accordance with U.S. GAAP requires that the Company make estimates and judgments that may affect the reported amounts of assets, liabilities, redeemable noncontrolling interest, revenues, expenses and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, judgments, and methodologies. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Changes in estimates are reflected in reported results in the period in which they become known.
Consolidation
The Company’s unaudited condensed consolidated financial statements reflect its financial statements and those of its subsidiaries in which the Company holds a controlling financial interest. For consolidated entities in which the Company owns or is exposed to less than 100% of the economics, the Company records net income (loss) attributable to noncontrolling interests in its consolidated statements of income equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. Intercompany balances and transactions are eliminated in consolidation.
The Company’s fiscal year is typically based on 52-weeks, with each quarter composed of 13 weeks ending on the last Saturday on, or closest to, March 31, June 30, September 30, and December 31.
Summary of Significant Accounting Policies
The Company’s significant accounting policies are described in Note 1, “Description of Business and Summary of Significant Accounting Policies,”Policies” in the Company’s Annual Report on Form 10-K for fiscal year 2017.2018 as well as Note 16, “Leases” in this Quarterly Report on Form 10-Q.
Newly Adopted Accounting Pronouncements
In MarchJune 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-05, “Income Taxes2018-07, “Stock Compensation (Topic 740) - Amendments718): Improvements to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (SAB 118).Nonemployee Share-Based Payment Accounting.This standard amends Accounting Standards Codification 740, Income Taxes (ASC 740) to provide guidance onASU 2018-07 aligns the accounting for the tax effects of U.S. Tax Reform pursuantshare-based payment awards issued to SAB 118, which allows companiesemployees and nonemployees as well as improves financial reporting for share-based payments to complete the accounting under ASC 740 within a one-year measurement period from the enactment date of U.S. Tax Reform. This standard is effective upon issuance and the Company has complied with the amendments. See Note 11, “Income Taxes” for further discussion.
In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The standard allows for reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects arising from the change in the reduction of the U.S. federal statutory income tax rate to 21% from 35%. During the three months ended March 31, 2018, the Company elected to early adopt this standard as permitted on a prospective basis, resulting in a reclassification of $3.3 million from accumulated other comprehensive income to retained earnings as a result of remeasuring the Company’s deferred tax liabilities related to its pension and other post-retirement benefit plan gains and losses. The Company’s policy is to release material stranded tax effects on a specific identification basis.
In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The standard requires an employer to disaggregate the service cost component from the other components of net benefit cost and provides explicit guidance on the presentation of the service cost component and the other components of net benefit cost in the statements of income.nonemployees. This standard became effective for the Company in the three months ended March 31, 2018. The Company applied the changes retrospectively to the presentation of the service cost component and the other components of net periodic pension cost in the statements of income for all periods presented as required. The adoption of this standard increased operating income by $0.2 million during the three months ended April 1,

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)


2017. In connection with the impact of operating income to the Company’s reportable segments, Research Models and Services (RMS) decreased by less than $0.1 million, Discovery and Safety Assessment (DSA) decreased by $0.3 million, Manufacturing Support (Manufacturing) decreased by less than $0.1 million, and Unallocated corporate increased by $0.6 million during the three months ended April 1, 2017.
In January 2017, the FASB issued ASU 2017-01, “Clarifying the Definition of a Business.” The standard clarifies the definition of a business by adding guidance to assist entities in evaluating whether transactions should be accounted for as acquisitions of assets or businesses. This standard became effective for the Company in the three months ended March 31, 201830, 2019 and did not have a significantmaterial impact on the consolidated financial statements and related disclosures.
In October 2016, the FASB issued ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory.” The standard requires the immediate recognition of tax effects for an intra-entity asset transfer other than inventory. This standard became effective for the Company in the three months ended March 31, 2018 and did not have a significant impact on the consolidated financial statements and related disclosures.
In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Liabilities.” This standard, including a subsequently issued amendment under ASU 2018-03, “Technical Corrections and Improvements to Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities”, requires equity investments that are not accounted for under the equity method of accounting to be measured at fair value with changes recognized in net income, simplifies the impairment assessment of certain equity investments, and updates certain presentation and disclosure requirements. This standard became effective for the Company in the three months ended March 31, 2018, resulting in an increase of $1.9 million to other assets with a corresponding increase to retained earnings and deferred taxes of $1.4 million and $0.5 million, respectively.
In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” The standard, including subsequently issued amendments, replaced most existing revenue recognition guidance in U.S. GAAP and permits the use of either a modified retrospective or cumulative effect transition method. The Company elected the modified retrospective transition method. The standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard became effective for the Company in the three months ended March 31, 2018. See Note 3, “Revenue From Contracts With Customers” for a discussion of the Company’s adoption of this standard and its impact on the consolidated financial statements and related disclosures.
Newly Issued Accounting Pronouncements
In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815) Targeted Improvements to Accounting for Hedging Activities.” ASU 2017-12 refines and expands hedge accounting for both financial and commodity risks. It also creates more transparency around how economic results are presented, both on the face of the financial statements and in the disclosures. In addition, this ASU makes certain targeted improvements to simplify the application of hedge accounting guidance. This standard became effective for the Company in the three months ended March 30, 2019 and did not have a material impact on the consolidated financial statements and related disclosures.
In February 2016, the FASB issued ASU 2016-02, “Leases.” The standard, including subsequently issued amendments, collectively referred to as Accounting Standards Codification (ASC) 842, “Leases”, established the principles that lessees and lessors will apply to report useful information to users of financial statements about the amount, timing and uncertainty of cash flows arising from a lease. The Company adopted this standard using the modified retrospective transition approach as applied to leases existing as of or entered into after the adoption date (December 30, 2018) in the three months ended March 30, 2019. See Note 16, “Leases” for a discussion of the Company’s adoption of this standard and its impact on the consolidated financial statements and related disclosures.
Newly Issued Accounting Pronouncements
In August 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computer Arrangement that is a Service Contract.” ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and

Early adoption is permitted. This update appliesThe Company is still evaluating the impact this standard will have on its consolidated financial statements and related disclosures.
In August 2018, the FASB issued ASU 2018-14, “Compensation Retirement Benefits - Defined Benefit Plans -General (Subtopic 715-20).” ASU 2018-14 removes the requirements to disclose the amounts in Accumulated other comprehensive income (loss) expected to be recognized as components of net periodic benefit cost over the next fiscal year and the related party disclosures about the amount of future annual benefits covered by insurance contracts. In addition, the ASU adds the requirement to disclose an explanation for any significant gains and losses related to changes in the benefit obligation for the period. The ASU is effective for fiscal years ending after December 15, 2020 and will be applied on a retrospective basis to all existing hedging relationshipsperiods presented. Early adoption is permitted. The Company is still evaluating the impact this standard will have on its consolidated financial statements and related disclosures.
In August 2018, the date of adoption withFASB issued ASU 2018-13, “Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the cumulative effect of adoption being reflectedDisclosure Requirements for Fair Value Measurement.” ASU 2018-13 removes the disclosure requirement for the amount and reasons for transfers between Level 1 and Level 2 fair value measurements as well as the process for Level 3 fair value measurements. In addition, the ASU adds the disclosure requirements for changes in unrealized gains and losses included in Other comprehensive income (loss) for recurring Level 3 fair value measurements held at the end of the reporting period as well as the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The ASU is effective for fiscal years beginning of theafter December 15, 2019, and interim periods within those fiscal year of adoption.years and will be applied on a retrospective basis to all periods presented. Early adoption is permitted. The Company is still evaluating the impact this standard will have on its consolidated financial statements and related disclosures.
In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment.” The standard simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. This standard is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and will be applied on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements and related disclosures.
In FebruaryJune 2016, the FASB issued ASU 2016-02, “Leases.2016-13, “Financial Instruments - Credit Losses.” The standard establishedrequires a financial asset measured at amortized cost basis, such as accounts receivable, to be presented at the principlesnet amount expected to be collected based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that lessees and lessors will apply to report useful information to usersaffect the collectability of financial statements about the amount, timing and uncertainty of cash flows arising from a lease.reported amount.

For contracts that were modified before the effective date, the Company reflected the aggregate effect of all modifications when identifying performance obligations and allocating transaction price in accordance with the practical expedient, which did not have a material effect on the cumulative impact of adopting ASC 606. The reported results for 2018 reflect the application of ASC 606 guidance while the historical results for 2017 were prepared under the guidance of ASC 605, “Revenue Recognition” (ASC 605).
The cumulative effect of applying ASC 606 to all contracts with customers that were not completed as of December 30, 2017 was immaterial. There is no material difference in the reporting of revenue for the 2018 period in accordance with ASC 606 when compared to ASC 605.
Revenue Recognition
Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to customers. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer (“transaction price”).
To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the most likely amount to which the Company expects to be entitled. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.
When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Generally, the Company does not extend payment terms beyond one year. Applying the practical expedient, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component for the 2018 period presented.three months ended March 30, 2019.
Contracts with customers may contain multiple performance obligations. For such arrangements, the transaction price is allocated to each performance obligation based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.
Contracts are often modified to account for changes in contract specifications and requirements. Contract modifications exist when the modification either creates new, or changes existing, enforceable rights and obligations. Generally, when contract modifications create new performance obligations, the modification is considered to be a separate contract and revenue is recognized prospectively. When contract modifications change existing performance obligations, the existing transaction price and measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.
Product revenue is generally recognized when the customer obtains control of the Company’s product, which occurs at a point in time, and may be upon shipment or upon delivery based on the contractual shipping terms of a contract. Service revenue is generally recognized over time as the services are delivered to the customer based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. Depending on which better depicts the transfer of value to the customer, the Company generally measures its progress using either cost-to-cost (input method) or right-to-invoice (output method). The Company uses the cost-to-cost measure of progress when it best depicts the transfer of value to the customer which occurs as the Company incurs costs on its contract, generally related to fixed fee service contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The costs calculation includes variables such as labor hours, allocation of overhead costs, research model costs, and subcontractor costs. Revenue is recorded proportionally as costs are incurred. The right to invoiceright-to-invoice measure of progress is generally related to rate per unit contracts, as the extent of progress towards completion is measured based on discrete service or time-based increments, such as samples tested or labor hourhours incurred. Revenue is recorded in the amount invoiced since that amount corresponds directly to the value of the Company’s performance to date.

The RMS business generates revenue through the commercial production and sale of research models and the provision of services related to the maintenance and monitoring of research models and management of clients’ research operations. Revenue from the sale of research models is recognized at a point in time when the customer obtains control of the product, which may be upon shipment or upon delivery based on the contractual shipping terms of a contract. Revenue generated from research models services is recognized over time and is typically based on a right-to-invoice measure of progress (output method) as invoiced amounts correspond directly to the value of the Company’s performance to date.
DSA
The Discovery and Safety Assessment business provides a full suite of integrated drug discovery services directed at the identification, screening and selection of a lead compound for drug development and offers a full range of safety assessment services including bioanalysis, drug metabolism, pharmacokinetics, toxicology and pathology.

Contract Balances from Contracts with Customers
The timing of revenue recognition, billings and cash collections results in billed receivables (client receivables), contract assets (unbilled revenue), contract liabilities (current and non-current deferred revenue), and customer deposits on the unaudited condensed consolidated balance sheets. The Company’s payment terms are generally 30 days in the United States and consistent with prevailing practice in international markets. WhenA contract asset is recorded when a right to consideration in exchange for goods or services transferred to a customer is conditioned other than the passage of time. Client receivables are recorded separately from contract assets since only the passage of time is required before consideration is due. A contract liability is recorded when consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a contract, a contract liability is recorded.contract. Contract liabilities are recognized as revenue after control of the products or services is transferred to the customer and all revenue recognition criteria have been met. The following table provides information about client receivables, contract assets, and contract liabilities from contracts with customers:

6. VENTURE CAPITAL INVESTMENTS
The Company invests in several venture capital funds that invest in start-up companies, primarily in the life sciences industry. The Company’s ownership interest in these funds ranges from 0.6%less than 1% to 12.0%. The Company accounts for the investments in limited partnerships (LPs), which are variable interest entities, under the equity method of accounting. For publicly-held investments in the LPs, the Company adjusts for changes in fair market value based on reported share holdings at the end of each fiscal quarter. The Company is not the primary beneficiary because it has no power to direct the activities that most significantly affect the LPs’ economic performance. The Company accounts for the investments in limited liability companies, which are not variable interest entities, under the equity method of accounting.

The Company has certain assets and liabilities recorded at fair value, which have been classified as Level 1, 2, or 3 within the fair value hierarchy:
Level 1 - Fair values are determined utilizing prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access,
Level 2 - Fair values are determined by utilizing quoted prices for identical or similar assets and liabilities in active markets or other market observable inputs such as interest rates, yield curves, and foreign currency spot rates,
Level 3 - Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.
The fair value hierarchy level is determined by asset and liability class based on the lowest level of significant input. The observability of inputs may change for certain assets or liabilities. This condition could cause an asset or liability to be reclassified between levels. The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each quarter. During the three months ended March 30, 2019 and March 31, 2018, and April 1, 2017, there were no transfers between levels.
Valuation methodologies used for assets and liabilities measured or disclosed at fair value are as follows:
Cash equivalents - Valued at market prices determined through third-party pricing services;
Mutual funds - Valued at the unadjusted quoted net asset value of shares held by the Company;
Foreign currency forward contracts - Valued using market observable inputs, such as forward foreign exchange points and foreign exchanges rates;
Life insurance policies - Valued at cash surrender value based on the fair value of underlying investments;
Debt instruments - The book value of the Company’s term and revolving loans, which are variable rate loans carried at amortized cost, approximates the fair value based on current market pricing of similar debt;debt. The book value of the Company’s 5.5% Senior Notes (Senior Notes) due in 2026, which are fixed rate debt, are carried at amortized cost. Fair value of the Senior Notes is based on quoted market prices and on borrowing rates available to the Company; and
Contingent consideration - Valued based on a probability weighting of the future cash flows associated with the potential outcomes.

The unobservable inputs used in the fair value measurement of the Company’s contingent consideration are the probabilities of successful achievement of certain financial targets and a discount rate. Increases or decreases in any of the probabilities of success would result in a higher or lower fair value measurement, respectively. Increases or decreases in the discount rate would result in a lower or higher fair value measurement, respectively.
Debt Instruments
The book value of the Company’s term and revolving loans, which are variable rate loans carried at amortized cost, approximates the fair value based on current market pricing of similar debt. As the fair value is based on significant other observable inputs, including current interest and foreign currency exchange rates, it is deemed to be Level 2 within the fair value hierarchy.
As of both March 30, 2019 and December 29, 2018, the book value of the Company’s Senior Notes, which is a fixed rate obligation carried at amortized cost, was $500.0 million. The fair value of the Company’s Senior Notes as of March 30, 2019 and December 29, 2018 was $520.0 million and $495.0 million, respectively. Fair value is based on quoted market prices as

The Company’s effective tax raterates for the three months ended March 30, 2019 and March 31, 2018 were 16.0% and April 1, 2017 was 15.5% and 39.8%, respectively. The slight increase in the 2019 period compared to the 2018 period was primarily attributable to tax benefits from favorable tax authority rulings in the 2018 period, partially offset by increased tax benefits from stock-based compensation deductions in the 2019 period.
For the three months ended March 31, 2018, the decrease was primarily attributable to the tax on the gain on the divestiture of the CDMO business of $18.0 million in the first quarter of 2017 and tax benefits from favorable taxing authority rulings for the three months ended March 31, 2018 of $2.7 million.
During the three months ended March 31, 2018,30, 2019, the Company’s unrecognized tax benefits decreasedincreased by $3.7$0.7 million to $21.0$19.5 million, primarily due to benefits from a favorable tax ruling, offset with an additional quarter of Canadian Scientific Research

and Experimental Development Credit reserves. The amount ofreserves as well as unfavorable foreign exchange. For the three months ended March 30, 2019, the unrecognized income tax benefits that would impact the effective tax rate decreasedincreased by $3.5$0.5 million to $19.3$18.1 million, for the same reasons listed above. The amount of accrued interest on unrecognized tax benefits was $2.6$2.9 million at March 31, 2018.30, 2019. The Company estimates that it is reasonably possible that the unrecognized tax benefits will decrease by up to $1.9$8.2 million over the next twelve-month period, primarily as a result ofdue to the outcome of pending tax audits.
The Company continues to monitor its accounting for the elements of U.S. Tax Reform enacted in December 2017.

The Company has not recorded any measurement period adjustments during the quarter ended March 31, 2018 to the provisional amounts recorded in the fourth quarter of 2017. The Company anticipates finalizing and recording any adjustments resulting from the release of any additional guidance and interpretations by the end of its fiscal year ending December 29, 2018.
The Company conducts business in a number ofseveral tax jurisdictions. As a result, it is subject to tax audits in jurisdictions including the U.S., U.K., China, France, Germany, Canada, Japan and Canada.India. With few exceptions, the Company is no longer subject to U.S. and international income tax examinations for years before 2015.

16. LEASES
Adoption of ASC Topic 842, “Leases” (ASC 842)
ASC 842 became effective for the Company on December 30, 2017.2018 and was adopted using the modified retrospective method for all leases that had commenced as of the effective date, along with certain available practical expedients. The Company elected to recognize any effects of applying the new standard as a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, which there were none. In addition, the Company elected to adopt the package of practical expedients permitted under the transition guidance within the new standard. The practical expedient package applied to leases that commenced prior to the effective date of the new standard and permits a reporting entity not to: i) reassess whether any expired or existing contracts are or contain leases, ii) reassess the historical lease classification for any expired or existing leases, and iii) reassess initial direct costs for any existing leases.
The reporting results for the three months ended March 30, 2019 reflect the application of ASC 842 guidance while the historical results for fiscal year 2018 were prepared under the guidance of ASC 840. The adoption of the new standard did not have a significant impact upon the Company’s condensed consolidated statements of income and cash flows. The adoption of the new standard resulted in the following impact to the condensed consolidated balance sheet: i) no significant change in the carrying values of assets and liabilities related to the Company’s finance leases, previously referred to as capital leases (See Note 9, “Long-Term Debt and Finance Lease Obligations”), ii) the derecognition of assets and related liabilities pertaining to certain build-to-suit arrangements previously accounted for under ASC 840 and recording them under the guidance of ASC 842, and iii) the recording of right-of-use assets and corresponding lease liabilities pertaining to the Company’s operating leases on the condensed consolidated balance sheet, adjusted for existing balances of prepaid rent and deferred rent liabilities as of the transition date. The cumulative effect of applying ASC 842 to all leases that had commenced as of December 30, 2018 was as follows:

Operating and Finance Leases
At inception of a contract, the Company determines if a contact meets the definition of a lease. A lease is a contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration.     The Company determines if the contract conveys the right to control the use of an identified asset for a period of time. The Company assesses throughout the period of use whether the Company has both of the following: (1) the right to obtain substantially all of the economic benefits from use of the identified asset, and (2) the right to direct the use of the identified asset. This determination is reassessed if the terms of the contract are changed. Leases are classified as

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


operating or finance leases based on the terms of the lease agreement and certain characteristics of the identified asset. Right-of-use assets and lease liabilities are recognized at lease commencement date based on the present value of the minimum future lease payments.
The Company leases laboratory, production, and office space (real estate), as well as land, vehicles and certain equipment under non-cancellable operating and finance leases. The carrying value of the Company’s right-of-use lease assets is substantially concentrated in its real estate leases, while the volume of lease agreements is primarily concentrated in vehicles and equipment leases. The Company’s policy is to not record leases with an original term of twelve months or less on the condensed consolidated balance sheets. The Company recognizes lease expense for these short-term leases on a straight-line basis over the lease term.
Certain lease agreements include rental payments that are adjusted periodically for inflation or other variables. In addition to rent, the leases may require the Company to pay additional amounts for taxes, insurance, maintenance and other expenses, which are generally referred to as non-lease components. Such adjustments to rental payments and variable non-lease components are treated as variable lease payments and recognized in the period in which the obligation for these payments was incurred. Variable lease components and variable non-lease components are not measured as part of the right of use asset and liability. Only when lease components and their associated non-lease components are fixed are they accounted for as a single lease component and are recognized as part of a right of use asset and liability. Total contract consideration is allocated to the combined fixed lease and non-lease component. This policy election applies consistently to all asset classes under lease agreements.
Most leases contain clauses for renewal at the Company’s option with renewal terms that generally extend the lease term from 1 to 5 years. Certain lease agreements contain options to purchase the leased property and options to terminate the lease. Payments to be made in option periods are recognized as part of the right-of-use lease assets and lease liabilities when it is reasonably certain that the option to extend the lease will be exercised or the option to terminate the lease will not be exercised, or is not at the Company’s option. The Company determines whether the reasonably certain threshold is met by considering contract-, asset-, market-, and entity-based factors.
A portfolio approach is applied to certain lease contracts with similar characteristics. The Company’s lease agreements do not contain any significant residual value guarantees or material restrictive covenants imposed by the leases.
The Company subleases a limited number of lease arrangements. Sublease activity is not material to the condensed consolidated financial statements.

Overview of Results of Operations and Liquidity

Revenue for the three months ended March 31, 201830, 2019 was $494.0$604.6 million compared to $445.8$494.0 million in the corresponding period in 2017.2018. This increase of $48.2$110.6 million, or 10.8%22.4%, was primarily due to the recent acquisition of MPI Research as well as growth in our DSA and Manufacturing segments. The positivesegments; partially offset by the negative effect of changes in foreign currency exchange rates increasedwhich decreased revenue by $20.8$13.9 million, or 4.6%2.8%, when compared to the corresponding period in 2017.2018.
In the three months ended March 31, 2018,30, 2019, our operating income and operating income margin were $67.8$69.8 million and 13.7%11.5%, respectively, compared with $69.7$67.8 million and 15.6%13.7%, respectively, in the corresponding period of 2017.2018. The decreaseincrease in operating income and operating income margin was primarily due to our recent acquisitions. The decreases in operating income margin were primarily due to increased amortization expense and costs related to our recent acquisitions; as well as continued investments in the business to support future growth of the Company.businesses, which includes increased investments in personnel (staffing levels and hourly wage increases) and facility expansions (primarily in the RMS and Biologics business). Offsetting the decreases in operating income margin were the realization of improved volume and pricing across our products and services portfolio.
Net income attributable to common shareholders increased to $52.6$55.1 million in the three months ended March 31, 2018,30, 2019, from $46.8$52.6 million in the corresponding period of 2017.2018. The increase in netNet income attributable to common shareholders was primarily due to a reduction of $21.3 millionthe increase in the provision foroperating income taxes resulting from the tax on the gain on the divestiture of the CDMO business of $18.0 million in the first quarter of 2017 and tax benefits from favorable taxing authority rulings for the three months ended March 31, 2018 of $2.7 million; partially offset by the absence of a $10.6 million gain recorded in other income, net on the CDMO divestiture in 2017.discussed above.
During the first three months of 2018,2019, our cash flows from operations was $60.1$14.9 million compared with $34.0$60.1 million for 2017.the same period in 2018. The increasedecrease was primarily driven by an increaseunfavorable changes in income from continuing operations and favorable timing of cash flows related to our operating assets and liabilities, specifically related to net contract balances from contracts with customers (collectively trade receivables, net; deferred revenue; and customer contract deposits) and accrued compensation compared to the prior year.year period.
On March 26, 2018, we amended and restated our $1.65 billion credit facility creating a $2.3B Credit Facility. The $2.3B Credit Facility provides for a $750.0 million term loan and a $1.55 billion multi-currency revolving facility. The term loan facility matures in 19 quarterly installments with the last installment due March 26, 2023. The revolving facility matures on March 26, 2023, and requires no scheduled payment before that date. Under specified circumstances, we have the ability to increase the term loan and/or revolving facility by up to $1.0 billion in the aggregate.

On April 3, 2018, we closed on the offering ofissued $500.0 million in aggregate principal amount of the Company’s 5.5% Senior Notes (Senior Notes) due 2026 in an unregistered offering. Interest on the Senior Notes is payable semi-annually on April 1 and October 1, of each year, beginning on October 1, 2018.
In March 2019, we detected unauthorized access into portions of our information systems and commenced an investigation into the incident, coordinated with U.S. federal law enforcement and leading cybersecurity experts, and promptly implemented a comprehensive containment and remediation plan. While the investigation is ongoing, we have determined that some client data was copied by a highly sophisticated, well-resourced intruder. We have not yet determined the potential revenue or financial impact related to this incident. 
We continue to move aggressively to further secure our information systems, which includes adding enhanced security features and monitoring procedures to further protect our client data. While we have taken substantial steps to minimize unauthorized access into our information systems, until our ongoing remediation process is complete, we will be unable to determine that this incident has been entirely remediated. We have not observed any further indications of continued unauthorized activity in our information systems.

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

Borrowings
On March 26, 2018, we amended and restated our $1.65 billion credit facility, creating our $2.3B Credit Facility which extended the maturity date for the credit facility. The $2.3B Credit Facility provides for a $750.0 million term loan and a $1.55 billion multi-currency revolving facility. The term loan facility matures in 19 quarterly installments with the last installment due March 26, 2023. The revolving facility matures on March 26, 2023, and requires no scheduled payment before that date.
On April 3, 2018, we entered into an indenture (Indenture) with MUFG Union Bank, N.A., in connection with the offering of $500.0 million in aggregate principal amount of the Senior Notes due in 2026 in an unregistered offering. Under the terms of the Indenture, interest on the Senior Notes is payable semi-annually on April 1 and October 1, beginning on October 1, 2018.
Amounts outstanding under our credit facilities and Senior Notes were as follows:

Under specified circumstances, we have the ability to increase the term loan and/or revolving facility by up to $1.0 billion in the aggregate. The interest rates applicable to the term loan and revolving facility under the $2.3B Credit Facility are, at our option, equal to either the base rate (which is the higher of (1) the prime rate, (2) the federal funds rate plus 0.50%, or (3) the one-month adjusted LIBOR rate plus 1.0%) or the adjusted LIBOR rate, plus an interest rate margin based upon our leverage ratio.
Upon the executionThe acquisition of theCitoxlab on April 29, 2019 for €448 million in cash (or approximately $500 million) was funded through a combination of cash on hand and proceeds from our $2.3B Credit Facility we paidunder the remaining $601.3 million balance on the previously drawn term loan. As of March 31, 2018, we had no outstanding term loans. On April 3, 2018, in conjunction with the purchase of MPI Research, we drew $750.0 million of term loan from the $2.3B Credit Facility.

Our stock-based compensation plans permit the netting of common stock upon vesting of restricted stock, restricted stock units, and performance share units in order to satisfy individual statutory tax withholding requirements.

Net cash provided by cash flows from operating activities represents the cash receipts and disbursements related to all of our activities other than investing and financing activities. Operating cash flow is derived by adjusting our income from continuing operations for (1) non-cash operating items such as depreciation and amortization, stock-based compensation, deferred income taxes, and gains on venture capital investments, and divestiture,impairment charges, as well as (2) changes in operating assets and liabilities, which reflect timing differences between the receipt and payment of cash associated with transactions and when they are recognized in our results of operations. For the three months ended March 31, 2018,30, 2019, compared to the three months ended April 1, 2017,March 31, 2018, the increasedecrease in cash provided by operating activities was primarily driven by an increase in income from continuing operations and positiveunfavorable changes in operating assets and liabilities, duespecifically related to net contract balances from contracts with customers (collectively trade receivables, net; deferred revenue; and customer contract deposits) resulting from the timingintegration of the information systems of MPI Research (having since been completed), which the Company acquired in 2018, and accrued compensation compared to the prior year period.

Refer to Note 9, “Long-Term Debt and Capital Lease Obligations” in our notes to the unaudited condensed consolidated financial statements in this Quarterly Report on Form 10-Q for additional information.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements prepared in accordance with generally accepted accounting principles in the U.S. The preparation of these financial statements requires us to make certain estimates and assumptions that may affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses during the reported periods and related disclosures. These estimates and assumptions are monitored and analyzed by us for changes in facts and circumstances, and material changes in these estimates could occur in the future. We base our estimates on our historical experience, trends in the industry, and various other factors that are believed to be reasonable under the circumstances. Actual results may differ from our estimates under different assumptions or conditions.
We believe that our application of the following accounting policies, each of which require significant judgments and estimates on the part of management, are the most critical to aid in fully understanding and evaluating our reported financial results: (1) revenue recognition, (2) income taxes, (3) goodwill and intangible assets, (4) valuation and impairment of long-lived assets, (5) pension and other retirement benefit plans, and (6) stock-based compensation. Our significant accounting policies are described in our Annual Report on Form 10-K for fiscal year 2017, with the exception of revenue recognition, which was updated upon the adoption of ASC 606 in the three month period ended March 31, 2018. Refer to2018 as well as Note 3, “Revenue From Contracts With Customers” in our notes to the unaudited condensed consolidated financial statements16, “Leases” in this Quarterly Report on Form 10-Q for our revenue recognition accounting policy.10-Q.
Recent Accounting Pronouncements
For a discussion of recent accounting pronouncements please refer to Note 1, “Basis of Presentation,” in our notes to the unaudited condensed consolidated financial statements in this Quarterly Report on Form 10-Q. Other than as discussed in Note 1, “Basis of Presentation,” we did not adopt any other new accounting pronouncements during the three months ended March 31, 201830, 2019 that had a significant effect on our unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
We are exposed to market risk from changes in interest rates and currency exchange rates, which could affect our future results of operations and financial condition. We manage our exposure to these risks through our regular operating and financing activities.
Interest Rate Risk
We are exposed to changes in interest rates while conducting normal business operations as a result of ongoing financing activities. As of March 31, 2018,30, 2019, our debt portfolio was comprised primarily of floating interest rate borrowings. A 100-basis point increase in interest rates would increase our annual pre-tax interest expense by $10.9$10.6 million.
Foreign Currency Exchange Rate Risk
We operate on a global basis and have exposure to some foreign currency exchange rate fluctuations for our financial position, results of operations, and cash flows.
While the financial results of our global activities are reported in U.S. dollars, our foreign subsidiaries typically conduct their operations in their respective local currency. The principal functional currencies of the Company’s foreign subsidiaries are the Euro, British Pound, Canadian Dollar, Chinese Yuan Renminbi, and Japanese Yen. During the three months ended March 31, 2018,30, 2019, the most significant drivers of foreign currency translation adjustment the Company recorded as part of otherOther comprehensive income (loss) were the Euro, British Pound, Canadian Dollar, and Chinese Yuan Renminbi, and Japanese Yen.Renminbi.
Fluctuations in the foreign currency exchange rates of the countries in which we do business will affect our financial position, results of operations, and cash flows. As the U.S. dollar strengthens against other currencies, the value of our non-U.S. revenue, expenses, assets, liabilities, and cash flows will generally decline when reported in U.S. dollars. The impact to net income as a result of a U.S. dollar strengthening will be partially mitigated by the value of non-U.S. expenses, which will decline when reported in U.S. dollars. As the U.S. dollar weakens versus other currencies, the value of the non-U.S. revenue, expenses, assets, liabilities, and cash flows will generally increase when reported in U.S. dollars. For the three months ended March 31, 2018,30,

2019, our revenue would have decreasedincreased by approximately $20.3$19.4 million and our operating income would have decreasedincreased by approximately $1.5$0.5 million, if the U.S. dollar exchange rate had strengthened by 10.0%, with all other variables held constant.

We attempt to minimize this exposure by using certain financial instruments in accordance with our overall risk management and our hedge policy. We do not enter into speculative derivative agreements.
During the three months ended March 31, 2018,30, 2019, we utilizedentered into foreign exchange forward contracts principally to hedge certain balance sheet exposures resulting fromlimit our foreign currency fluctuations. Noexposure related to both intercompany loans and a U.S. dollar denominated loan borrowed by a non-U.S. Euro functional currency entity under our $2.3B Credit Facility. We did not have any foreign currency contracts were open related to intercompany loans as of March 31, 2018.30, 2019.
Item 4. Controls and Procedures
(a)   Evaluation of Disclosure Controls and Procedures
Based on their evaluation, required by paragraph (b) of Rules 13a-15 or 15d-15, promulgated by the Securities Exchange Act of 1934, as amended (Exchange Act), the Company’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act, are effective, at a reasonable assurance level, as of March 31, 2018,30, 2019, to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurances of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures.
(b) Changes in Internal Controls
The Company continued to execute a plan to centralize certain accounting transaction processing functions to internal shared service centers during the three months ended March 31, 2018.30, 2019. There were no other material changes in the Company’s internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of the Exchange Act Rules 13a-15 or 15d-15 that occurred during the quarter ended March 31, 201830, 2019 that materially affected, or were reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
Please refer to Note 15,17, “Commitments and Contingencies” in our notes to the unaudited condensed consolidated financial statements in this Quarterly Report on Form 10-Q.
Item 1A. Risk Factors
In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for fiscal year 2017,2018, which could materially affect our business, financial condition, and/or future results. The risks described in our Annual Report on Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, and/or operating results. There have been no material changes to the risk factors set forth in our Annual Report on Form 10-K for fiscal year 2017.2018, except as disclosed below.
We have in the past experienced and in the future could experience an unauthorized access into our information systems.
We operate large and complex information systems that contain significant amounts of client data. As a routine element of our business, we collect, analyze, and retain substantial amounts of data pertaining to the non-clinical studies we conduct for our clients. Unauthorized third parties could attempt to gain entry to such information systems for the purpose of stealing data or disrupting the systems. While we have taken measures to protect them from intrusion, in March 2019, we detected evidence that an unauthorized third party has accessed certain of our information systems and acquired data. The Company’s investigation is ongoing, but we believe that the incident is attributable to a sophisticated intruder. We are working with a leading data security firm to assist in our investigation, and are also coordinating with law enforcement authorities. The investigation indicates that the affected information included client information. 
Our contracts with our clients typically contain provisions that require us to keep confidential the information generated from the studies we conduct. The unauthorized access detected, as well as any future breaches, could expose us to significant harm including termination of customer contracts, damage to our customer relationships, damage to our reputation and potential legal claims from customers, employees and others. In addition, we may face investigations by government regulators and agencies as a result of this incident or as a result of future incidents.
While the Company is in the process of implementing additional security safeguards, it is expected to take a number of months for all of these additional security safeguards to be fully implemented. While we have taken steps to limit the unauthorized third party’s access to our computer systems, we will be unable to determine that this matter has been entirely contained until the additional steps to secure our information systems have been fully implemented. In addition, there can be no assurance that the additional security safeguards will be successful. In the event that additional data is accessed prior to the full implementation of these additional security safeguards or in the event that such additional security safeguards are unsuccessful, we could suffer significant harm.
