NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1. BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION

The accompanying condensed consolidated financial statements of IDEXX Laboratories, Inc. (“IDEXX,” the “Company,” “we” or “our”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the requirements of Regulation S-X, Rule 10-01 for financial statements required to be filed as a part of Form 10-Q.

The accompanying condensed consolidated financial statements include the accounts of IDEXX Laboratories, Inc. and our wholly-owned and majority-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

The accompanying condensed consolidated financial statements reflect, in the opinion of our management, all adjustments necessary for a fair presentation of our financial position and results of operations. All such adjustments are of a recurring nature. The consolidated balance sheet data at December 31, 2010 was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. The results of operations for the three and nine months ended September 30, 2011 are not necessarily indicative of the results to be expected for the full year or any future period. These condensed consolidated financial statements should be read in conjunction with this Quarterly Report on Form 10-Q for the quarter ended September 30, 2011 and our Annual Report on Form 10-K for the year ended December 31, 2010 filed with the Securities and Exchange Commission.

Certain reclassifications have been made to the prior year condensed consolidated financial statements to conform to the current year presentation. Reclassifications had no material impact on previously reported results of operations, financial position or cash flows.

NOTE 2. ACCOUNTING POLICIES

Significant Accounting Policies

The significant accounting policies used in preparation of these condensed consolidated financial statements for the nine months ended September 30, 2011 are consistent with those discussed in Note 3 to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2010.

Recent Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (“FASB”) issued amended accounting guidance for goodwill in order to simplify how companies test goodwill for impairment. The amendments permit a company to first assess the qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The more-likely-than-not threshold is defined as having a likelihood of more than 50 percent. If, after assessing the totality of events or circumstances, a company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted. We do not expect the adoption of this accounting pronouncement to have a material effect on our financial statements when implemented.

In June 2011, the FASB issued an amendment to the accounting guidance for presentation of comprehensive income. Under the amended guidance, a company may present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In either case, a company is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. Regardless of choice in presentation, of which we are currently evaluating, a company is required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. For public companies, the amendment is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and shall be applied retrospectively. Early adoption is permitted. Other than a change in presentation, the implementation of this accounting pronouncement is not expected to have a material impact on our financial statements when implemented.

In May 2011, the FASB issued authoritative guidance that amends the existing requirements for fair value measurement and disclosure. Among other things, the guidance expands the disclosure requirements around fair value measurements categorized in Level 3 of the fair value hierarchy and requires disclosure of the level in the fair value hierarchy of items that are not measured at fair value in the statement of financial position but whose fair value must be disclosed. It also clarifies and expands upon existing requirements for measurement of the fair value of financial assets and liabilities as well as instruments classified in shareholders’ equity. The guidance is effective for interim and annual periods beginning after December 15, 2011. We do not expect the adoption of the guidance to have a material impact on our financial statements when implemented.

There are no other new accounting pronouncements adopted or enacted during the three and nine months ended September 30, 2011 that had, or are expected to have, a material impact on our financial statements.

NOTE 3. SHARE-BASED COMPENSATION

The fair value of options, restricted stock units, deferred stock units with vesting conditions and employee stock purchase rights awarded during the three and nine months ended September 30, 2011 totaled $0.1 million and $23.6 million, respectively, compared to $0.5 million and $15.8 million for the three and nine months ended September 30, 2010, respectively.

The total unrecognized compensation expense, net of estimated forfeitures, for unvested share-based compensation awards outstanding at September 30, 2011 was $32.4 million, which will be recognized over a weighted average of approximately 1.9 years.

Options

We determine the assumptions used in the valuation of option awards as of the date of grant. Differences in the stock price volatility, expected term or risk-free interest rate may result in distinct valuation assumptions at each grant date. As such, we may use different assumptions for options granted throughout the year. Option awards are granted with an exercise price equal to the closing market price of our common stock at the date of grant. We have never paid any cash dividends on our common stock and we have no present intention to pay a dividend; therefore, we assume that no dividends will be paid over the expected terms of option awards. The weighted averages of the valuation assumptions used to determine the fair value of each option award on the date of grant and the weighted average estimated fair values were as follows:

	For the Nine Months Ended September 30,
	2011			2010

Expected stock price volatility		33	%		31	%
Expected term, in years		4.8			4.9
Risk-free interest rate		2.3	%		2.3	%

Weighted average fair value of options granted	$	24.87		$	16.56

NOTE 4. INVENTORIES

Inventories include material, labor and overhead, and are stated at the lower of cost (first-in, first-out) or market. The components of inventories were as follows (in thousands):

	September 30,		December 31,
	2011		2010

Raw materials	$	28,892	$	26,758
Work-in-process		14,111		13,790
Finished goods		94,140		87,337
	$	137,143	$	127,885

NOTE 5. GOODWILL AND INTANGIBLE ASSETS

We acquired a business in September 2011 for a purchase price of $3.2 million, the majority of which was allocated to intangible assets and to goodwill. Intangible assets other than goodwill decreased during the nine months ended September 30, 2011 as continued amortization of our assets more than offset the impact of the business acquisition. Changes in foreign currency exchange rates did not have a material impact on goodwill and other intangible assets during the nine months ended September 30, 2011.

All assets acquired in connection with the September 2011 business acquisition were assigned to the Companion Animal Group (“CAG”) segment. The results of operations of the acquired business have been included in our financial statements since the acquisition date. Pro forma information has not been presented because such information is not material to the financial statements taken as a whole.

NOTE 6. OTHER NONCURRENT ASSETS

Other noncurrent assets consisted of the following (in thousands):

	September 30,		December 31,
	2011		2010

Investment in long-term product supply arrangements	$	12,421	$	12,120
Customer acquisition costs, net		16,547		5,470
Other assets		14,986		12,374
	$	43,954	$	29,964

NOTE 7. ACCRUED LIABILITIES

Accrued liabilities consisted of the following (in thousands):

	September 30, 2011		December 31, 2010

Accrued expenses	$	41,081	$	36,150
Accrued employee compensation and related expenses		49,076		47,914
Accrued taxes		16,642		12,320
Accrued customer programs		30,000		22,214
	$	136,799	$	118,598

NOTE 8. DEBT

In July 2011, we refinanced our existing $200 million unsecured revolving credit facility by entering into an amended and restated credit agreement relating to a five-year unsecured revolving credit facility in the principal amount of $300 million with a syndicate of multinational banks, which matures on July 25, 2016 (the new credit facility and the previous credit facility are referred to collectively as the “Credit Facility”) and requires no scheduled prepayments before that date. Though the Credit Facility does not mature until July 25, 2016, all amounts borrowed under the terms of the Credit Facility are reflected in the current liabilities section in the accompanying condensed consolidated balance sheets because the Credit Facility contains a subjective material adverse event clause, which allows the debt holders to call the loans under the Credit Facility if we fail to notify the syndicate of such an event. The funds available under the Credit Facility as of September 30, 2011 and December 31, 2010 reflect a further reduction due to the issuance of a letter of credit for $1.0 million, which was issued in connection with our workers’ compensation policy covering claims for the years 2009, 2010 and 2011. Applicable interest rates on borrowings under the Credit Facility generally range from 0.875 to 1.25 percentage points (“Credit Spread”) above the London interbank rate (“LIBOR”) or the Canadian Dollar-denominated bankers’ acceptance rate (“CDOR”), dependent on our leverage ratio, or the prevailing prime rate plus a maximum spread of up to 0.25%, dependent on our leverage ratio. Under the Credit Facility, we pay quarterly commitment fees of 0.15% to 0.30%, dependent on our leverage ratio, on any unused commitment. The obligations under the Credit Facility may be accelerated upon the occurrence of an event of default under the Credit Facility, which includes customary events of default including, without limitation, payment defaults, defaults in the performance of affirmative and negative covenants, the inaccuracy of representations or warranties, bankruptcy and insolvency related defaults, defaults relating to judgments, certain events related to employee pension benefit plans under the Employee Retirement Income Security Act of 1974, the failure to pay specified indebtedness, and a change of control default. The Credit Facility contains affirmative, negative and financial covenants customary for financings of this type. The negative covenants include restrictions on liens, indebtedness of subsidiaries of the Company, fundamental changes, investments, transactions with affiliates and certain restrictive agreements. The financial covenant is a consolidated leverage ratio test that requires our ratio of debt to earnings before interest, taxes, depreciation and amortization, defined as the consolidated leverage ratio under the terms of the Credit Facility, not to exceed 3-to-1. At September 30, 2011, we were in compliance with the covenants of the Credit Facility.

In 2009, we entered into two forward fixed interest rate swap agreements to manage the economic effect of variable interest obligations. Under these agreements, beginning on March 31, 2010 the variable interest rate associated with $80 million of borrowings outstanding under the Credit Facility became effectively fixed at 2% plus the Credit Spread through March 30, 2012. In August 2011, we entered into two additional forward fixed interest rate swap agreements for the same purpose. Under these agreements, beginning on March 30, 2012, the variable interest rate associated with $40 million of borrowings outstanding under the Credit Facility will become effectively fixed at 1.36% plus the Credit Spread through June 30, 2016 and beginning on March 28, 2013, the variable interest rate associated with an additional $40 million of borrowings outstanding under the Credit Facility will become effectively fixed at 1.64% plus the Credit Spread through June 30, 2016. See Note 17 for a discussion of our derivative instruments and hedging activities.

At September 30, 2011, our mortgage is consistent with that discussed in Note 11 to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2010.

NOTE 9. WARRANTY RESERVES

We provide for the estimated cost of instrument warranties in cost of product revenue at the time revenue is recognized based on the estimated cost to repair the instrument over its warranty period. As we sell new instruments, our provision for warranty expense increases. Cost of product revenue reflects not only estimated warranty expense for the systems sold in the current period, but also any changes in estimated warranty expense for the installed base that results from our quarterly evaluation of service experience. Our actual warranty obligation is affected by instrument performance in the customers’ environment and costs incurred in servicing instruments. Should actual service rates or costs differ from our estimates, which are based on historical data and projections of future costs, revisions to our estimated warranty liability would be required. The liability for warranties is included in accrued liabilities in the accompanying condensed consolidated balance sheets.

The following is a summary of changes in accrued warranty reserves for the three and nine months ended September 30, 2011 and 2010 (in thousands):

	For the Three Months Ended September 30,						For the Nine Months Ended September 30,
	2011			2010			2011			2010

Balance, beginning of period	$	1,675		$	2,597		$	2,196		$	3,104
Provision for warranty expense		668			740			1,763			2,296
Change in estimate, balance beginning of period		(172	)		(463	)		(394	)		(1,021	)
Settlement of warranty liability		(604	)		(760	)		(1,998	)		(2,265	)
Balance, end of period	$	1,567		$	2,114		$	1,567		$	2,114

NOTE 10. REPURCHASES OF COMMON STOCK

The following is a summary of our open market common stock repurchases for the three and nine months ended September 30, 2011 and 2010 (in thousands, except per share amounts):

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2011		2010		2011		2010

Shares repurchased		886		567		2,183		2,080
Total cost of shares repurchased	$	67,597	$	33,433	$	166,016	$	117,157
Average cost per share	$	76.27	$	58.98	$	76.04	$	56.32

We primarily acquire shares by means of repurchases in the open market. However, we also acquire shares that are surrendered by employees in payment for the minimum required withholding taxes due on the vesting of restricted stock units and the settlement of deferred stock units, otherwise referred to herein as employee surrenders. Shares acquired through employee surrenders were not significant for both the three months ended September 30, 2011 and 2010. We acquired 54,940 shares at a total cost of $4.3 million in connection with such employee surrenders for the nine months ended September 30, 2011 compared to 51,168 shares at a total cost of $2.7 million for the nine months ended September 30, 2010. Employee surrenders are generally most significant during the first quarter of each year in connection with the vesting of our annual restricted stock unit awards.

In 2011, we began issuing shares of treasury stock upon the vesting of certain restricted stock units. The number of shares of treasury stock issued during the three and nine months ended September 30, 2011 was not significant.

Our effective income tax rates were 30.8% and 31.1% for the three and nine months ended September 30, 2011 compared to 29.5% and 30.8% for the three and nine months ended September 30, 2010. The increase in our effective income tax rate for both the three and nine months ended September 30, 2011 as compared to the same periods of the prior year were due primarily to lower tax benefits recognized in connection with the expiration of certain statutes of limitations and with U.S. manufacturing activities. These unfavorable impacts were partly offset by federal research and development tax incentives available during the three and nine months ended September 30, 2011, but not available during the three and nine months ended September 30, 2010.

NOTE 12. COMPREHENSIVE INCOME

The following is a summary of comprehensive income for the three and nine months ended September 30, 2011 and 2010 (in thousands):

NOTE 13. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income attributable to IDEXX Laboratories, Inc. stockholders by the weighted average number of shares of common stock and vested deferred stock units outstanding during the period. Vested deferred stock units outstanding are included in shares outstanding for basic and diluted earnings per share because the associated shares of our common stock are issuable for no cash consideration, the number of shares of our common stock to be issued is fixed and issuance is not contingent. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased for the assumed exercise of dilutive options and assumed issuance of unvested restricted stock units and unvested deferred stock units using the treasury stock method, unless the effect is anti-dilutive.

The following is a reconciliation of shares outstanding for basic and diluted earnings per share for the three and nine months ended September 30, 2011 and 2010 (in thousands):

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2011		2010		2011		2010

Shares outstanding for basic earnings per share		56,699		57,620		57,141		57,799

Shares outstanding for diluted earnings per share:
Shares outstanding for basic earnings per share		56,699		57,620		57,141		57,799
Dilutive effect of share-based payment awards		1,308		1,656		1,495		1,892
		58,007		59,276		58,636		59,691

Certain options to acquire shares have been excluded from the calculation of shares outstanding for diluted earnings per share because they were anti-dilutive. The following table presents information concerning those anti-dilutive options for the three and nine months ended September 30, 2011 and 2010 (in thousands):

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2011		2010		2011		2010

Weighted average number of shares underlying anti-dilutive options		665		598		566		654

NOTE 14. COMMITMENTS, CONTINGENCIES AND GUARANTEES

As discussed in our Annual Report on Form 10-K for the year ended December 31, 2010, in January 2010, we received a letter from the U.S. Federal Trade Commission (“FTC”), stating that it was conducting an investigation to determine whether we or others have engaged in, or are engaging in, unfair methods of competition in violation of Section 5 of the Federal Trade Commission Act (“FTC Act”) through pricing or marketing policies for companion animal veterinary products and services, including but not limited to exclusive dealing or tying arrangements with distributors or end-users of those products or services. The letter stated that the FTC has not concluded that we or anyone else has violated Section 5 of the FTC Act. In April 2010 and August 2011, we received subpoenas from the FTC requesting that we provide the FTC with documents and information relevant to this investigation. We are cooperating fully with the FTC in its investigation.

In November 2010, we received notification that the United Kingdom Office of Fair Trading (“OFT”) was conducting an investigation to determine whether we had engaged in, or are engaging in, practices foreclosing the supply of companion animal diagnostic testing services in violation of the United Kingdom Competition Act of 1998. We have provided the OFT with documents and information relevant to this investigation as requested and we are cooperating fully with the OFT on this matter.

We believe that our marketing and sales practices for companion animal veterinary products and services do not violate the antitrust laws of the U.S., U.K., or any other country. At this time, we cannot predict whether government investigations will lead to enforcement proceedings, or what the outcomes of those proceedings will be, including whether those outcomes will involve the payment of fines or penalties. As such, we have not recognized a loss contingency as potential losses related to either investigation are neither probable nor can they reasonably be estimated through the date of the filing of this Quarterly Report on Form 10-Q.

Other commitments, contingencies and guarantees at September 30, 2011 are consistent with those discussed in Note 14 to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2010.

NOTE 15. SEGMENT REPORTING

We operate primarily through three business segments: diagnostic and information technology-based products and services for the veterinary market, which we refer to as CAG, water quality testing products (“Water”) and products for livestock and poultry health, which we refer to as Livestock and Poultry Diagnostics (“LPD”). We also operate two smaller operating segments that comprise products for testing milk quality (“Dairy”) and products for the human point-of-care medical diagnostics market (“OPTI Medical”). Financial information about our Dairy and OPTI Medical operating segments is combined and presented with one of our remaining pharmaceutical product lines and our out-licensing arrangements in an “Other” category because they do not meet the quantitative or qualitative thresholds for reportable segments.

The accounting policies of the segments are consistent with those discussed in Notes 1 and 15 to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2010, except for the change in our measure of segment profitability during the three months ended March 31, 2011 as discussed below. Intersegment revenues, which are not included in the table below, were not significant for the three and nine months ended September 30, 2011 and 2010.

On January 1, 2011, we changed the measure of profitability for our reportable segments. As a result of this change, a portion of corporate support function expenses and personnel-related expenses, certain manufacturing costs and certain foreign currency exchange gains and losses are no longer allocated to our reportable segments and, instead, are reported under the caption “Unallocated Amounts.” Similar to our treatment of share-based compensation expense, we estimate corporate support function expenses and certain personnel-related costs and allocate the estimated expense to the operating segments. This allocation differs from the actual expense and consequently yields a difference that is now reported under the caption “Unallocated Amounts.” With respect to manufacturing costs, the costs reported in our operating segments include our standard cost for products sold and any variances from standard cost for products purchased or manufactured within the period. We capitalize these variances for inventory on hand at the end of the period to record inventory in accordance with U.S. GAAP. We then record these costs as cost of product revenue as that inventory is sold. The impact to cost of product revenue resulting from this variance capitalization and subsequent expense recognition is now reported within the caption “Unallocated Amounts.” Prior to January 1, 2011, “Unallocated Amounts” included primarily corporate research and development expenses that did not align with one of our existing business or service categories and the difference between estimated and actual share-based compensation expense. The segment income (loss) from operations discussed within this report for the three and nine months ended September 30, 2010 have been restated to conform to our new measure of segment profitability. This change in measure of segment profitability did not have a material impact on the results of operations for any of our individual segments. There was no change to the business composition of our reportable segments.

The following is a summary of segment performance for the three and nine months ended September 30, 2011 and 2010 (in thousands):

NOTE 16. FAIR VALUE MEASUREMENTS

U.S. GAAP defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. U.S. GAAP also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value.

There are three levels of inputs that may be used to measure fair value:

Level 1

Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date.

Level 2

Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Foreign currency exchange contracts classified as derivative instruments are valued using an income approach, based on the present value of the forward rate less the contract rate multiplied by the notional amount. The product of this calculation is then adjusted for counterparty risk. Interest rate swaps classified as derivative instruments are valued using an income approach, utilizing a discounted cash flow analysis based on the terms of the contract and the interest rate curve and is then adjusted for counterparty risk.

Level 3

Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. At September 30, 2011 and December 31, 2010, we had no Level 3 assets or liabilities.

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

We did not have any significant nonfinancial assets or nonfinancial liabilities which required remeasurement during the nine months ended September 30, 2011. We did not have any transfers between Level 1 and Level 2 measurements during the nine months ended September 30, 2011.

The following tables set forth our assets and liabilities that were measured at fair value on a recurring basis at September 30, 2011 and at December 31, 2010 by level within the fair value hierarchy (in thousands):

As of September 30, 2011	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance at September 30, 2011

Deferred compensation(4)		2,222		-		-		2,222
Interest rate swaps(5)		-		1,611		-		1,611

(1)	Money market funds are included within cash and cash equivalents.

(2)	Equity mutual funds relate to a deferred compensation plan that was assumed as part of a previous business combination. This amount is included within other long-term assets, net. See number (4) below for a discussion of the related deferred compensation liability.

(3)	Foreign currency exchange contracts are included within other current assets; other long-term assets, net; accrued liabilities; or other long-term liabilities depending on the gain (loss) position and anticipated settlement date.

(4)	Deferred compensation plans are included within other long-term liabilities. The fair value of our deferred compensation plan is indexed to the performance of the underlying equity mutual funds discussed in number (2) above.

(5)	Interest rate swaps are included within accrued liabilities.

The estimated fair value of certain financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and the current portion of our mortgage, approximate carrying value due to their short maturity. The estimated fair value of our Credit Facility approximates carrying value as we believe that we could obtain an unsecured revolving credit facility bearing interest rates, based on current market conditions, similar to those effective under our current Credit Facility, which was refinanced in July 2011. The estimated fair value of the noncurrent portion of our mortgage approximates the carrying value based on current market prices for similar debt issues with similar remaining maturities.

Financial instruments that potentially subject us to concentrations of credit risk are principally cash, cash equivalents, accounts receivable, investments and derivatives. To mitigate such risk with respect to cash, cash equivalents and investments, we place our cash with highly-rated financial institutions, in non-interest bearing accounts that are fully insured by the U.S. government and money market funds invested in government securities. Concentration of credit risk with respect to accounts receivable is limited to certain customers to whom we make substantial sales. To reduce risk, we routinely assess the financial strength of our most significant customers and monitor the amounts owed to us, taking appropriate action when necessary. As a result, we believe that accounts receivable credit risk exposure is limited. We maintain an allowance for doubtful accounts, but historically have not experienced any significant losses related to an individual customer or group of customers in any particular industry or geographic area. To mitigate concentration of credit risk with respect to derivatives we enter into transactions with highly-rated financial institutions, enter into master netting arrangements with the counterparties to our derivative transactions and frequently monitor the credit worthiness of our counterparties.

NOTE 17. DERIVATIVE INSTRUMENTS AND HEDGING

Disclosure within this footnote is presented to provide transparency about how and why we use derivative instruments, how the instruments and related hedged items are accounted for, and how the instruments and related hedged items affect our financial position, results of operations and cash flows. Derivative instruments are recognized on the balance sheet as either assets or liabilities at fair value with a corresponding offset to other comprehensive income (“OCI”), which is presented net of tax.

We are exposed to certain risks related to our ongoing business operations. The primary risks that we manage by using derivative instruments are foreign currency exchange risk and interest rate risk. Our subsidiaries enter into foreign currency exchange contracts to manage the exchange risk associated with their forecasted intercompany inventory purchases and sales for the next year. From time to time, we may also enter into foreign currency exchange contracts to minimize the impact of foreign currency fluctuations associated with specific, significant transactions. We enter into interest rate swaps to minimize the impact of interest rate fluctuations associated with our variable-rate debt.

The primary purpose of our foreign currency hedging activities is to protect against the volatility associated with foreign currency transactions. We also utilize natural hedges to mitigate our transaction and commitment exposures. Our corporate policy prescribes the range of allowable hedging activity. We enter into exchange contracts with large multinational financial institutions and we do not hold or engage in transactions involving derivative instruments for purposes other than risk management. Our accounting policies for these contracts are based on our designation of such instruments as hedging transactions. Market gains and losses are deferred in OCI until the contract matures, which is the period when the related obligation is settled. We primarily utilize forward exchange contracts with durations of less than 24 months. We present our derivative assets and liabilities on the balance sheet on a gross basis.

Cash Flow Hedges

We have designated our foreign currency exchange contracts and variable-to-fixed interest rate swaps as cash flow hedges. For derivative instruments that are designated as cash flow hedges, changes in the fair value of the derivatives are recognized in OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. We de-designate derivative instruments from hedge accounting when the probability of the hedged transaction occurring becomes less than probable, but remains reasonably possible. For de-designated instruments, the gain or loss from the time of de-designation through maturity of the instrument is recognized in earnings. Any gain or loss in OCI at the time of de-designation is reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. We immediately record in earnings the extent to which a hedge is not effective in achieving offsetting changes in fair value of the hedged item.

We did not de-designate any instruments from hedge accounting treatment during the three and nine months ended September 30, 2011 or 2010. Gains or losses related to hedge ineffectiveness recognized in earnings during the three and nine months ended September 30, 2011 and 2010 were not material. At September 30, 2011, the estimated net amount of gains, net of tax, that are expected to be reclassified out of OCI and into earnings within the next 12 months was $1.3 million if exchange and interest rates do not fluctuate from the levels at September 30, 2011.

We enter into foreign currency exchange contracts for amounts that are less than the full value of forecasted intercompany inventory purchases and sales. Our hedging strategy related to intercompany inventory purchases and sales is to employ the full amount of our hedges for the succeeding year at the conclusion of our budgeting process for that year, which is complete by the end of the preceding year. Quarterly, we enter into contracts to hedge incremental portions of anticipated foreign currency transactions for the current and following year. As a result, the notional value of foreign currency exchange contracts outstanding may be higher throughout the year in comparison to the amounts outstanding at the end of the year. Accordingly, our risk with respect to foreign currency exchange rate fluctuations may vary throughout each annual cycle.

In March 2009, we entered into two forward fixed interest rate swap agreements to manage the economic effect of variable interest obligations on amounts borrowed under the terms of our Credit Facility. Under these agreements, beginning on March 31, 2010 the variable interest rate associated with $80 million of borrowings outstanding under the Credit Facility became effectively fixed at 2% plus the Credit Spread through March 30, 2012. In August 2011, we entered into two additional forward fixed interest rate swap agreements for the same purpose. Under these agreements, beginning on March 30, 2012, the variable interest rate associated with $40 million of borrowings outstanding under the Credit Facility will become effectively fixed at 1.36% plus the Credit Spread through June 30, 2016 and beginning on March 28, 2013, the variable interest rate associated with an additional $40 million of borrowings outstanding under the Credit Facility will become effectively fixed at 1.64% plus the Credit Spread through June 30, 2016.

■ Business Overview and Trends

Operating segments. We operate primarily through three business segments: diagnostic and information technology-based products and services for the veterinary market, which we refer to as our Companion Animal Group (“CAG”), water quality testing products (“Water”) and products for livestock and poultry health, which we refer to as Livestock and Poultry Diagnostics (“LPD”). We also operate two smaller operating segments that comprise products for testing milk quality (“Dairy”) and products for the human point-of-care medical diagnostics market (“OPTI Medical”). Financial information about our Dairy and OPTI Medical operating segments is combined and presented with one of our remaining pharmaceutical product lines and our out-licensing arrangements in an “Other” category because they do not meet the quantitative or qualitative thresholds for reportable segments. See Note 15 to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for financial information about our segments and the section entitled “Description of Business by Segment” under the heading “Item 1. Business” in our Annual Report on Form 10-K for the year ended December 31, 2010 for additional description of our segments.

CAG develops, designs, manufactures and distributes products and performs services for veterinarians, primarily related to diagnostics and information management. Water develops, designs, manufactures and distributes a range of products used in the detection of various microbiological parameters in water. LPD develops, designs, manufactures and distributes diagnostic tests and related instrumentation that are used to detect a wide range of diseases and to monitor health status in livestock and poultry. Dairy develops, designs, manufactures and distributes products to detect contaminants in milk. OPTI Medical develops, designs, manufactures and distributes point-of-care electrolyte and blood gas analyzers and related consumable products for the human medical diagnostics market. Further, OPTI Medical manufactures our VetStat® Electrolyte and Blood Gas Analyzer, a component of our Catalyst Dx® Analyzer and electrolyte consumables used with our Catalyst Dx® Analyzer.

On January 1, 2011, we changed the measure of profitability for our reportable segments. As a result of this change, a portion of corporate support function expenses and personnel-related expenses, certain manufacturing costs and certain foreign currency exchange gains and losses are no longer allocated to our reportable segments and, instead, are reported under the caption “Unallocated Amounts.” Similar to our treatment of share-based compensation expense, we estimate corporate support function expenses and certain personnel-related costs and allocate the estimated expense to the operating segments. This allocation differs from the actual expense and consequently yields a difference that is now reported under the caption “Unallocated Amounts.” With respect to manufacturing costs, the costs reported in our operating segments include our standard cost for products sold and any variances from standard cost for products purchased or manufactured within the period. We capitalize these variances for inventory on hand at the end of the period to record inventory in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). We then record these costs as cost of product revenue as that inventory is sold. The impact to cost of product revenue resulting from this variance capitalization and subsequent expense recognition is now reported within the caption “Unallocated Amounts.” Prior to January 1, 2011, “Unallocated Amounts” included primarily corporate research and development expenses that did not align with one of our existing business or service categories and the difference between estimated and actual share-based compensation expense. The segment income (loss) from operations discussed within this report for the three and nine months ended September 30, 2010 have been restated to conform to our new measure of segment profitability. This change in measure of segment profitability did not have a material impact on the results of operations for any of our individual segments. There was no change to the business composition of our reportable segments.

Effects of Certain Factors on Results of Operations

Distributor Purchasing and Inventories. The instrument consumables and rapid assay products in our CAG segment are sold in the U.S. and certain other geographies by third party distributors, who purchase products from us and sell them to veterinary practices, which are the end users. As a result, distributor purchasing dynamics have an impact on our reported sales of these products. Distributor purchasing dynamics may be affected by many factors and may be unrelated to underlying end-user demand for our products. Consequently, reported results may reflect fluctuations in distributors’ inventories and not necessarily reflect changes in underlying end-user demand. Therefore, we believe it is important to track distributor sales to end users and to distinguish between the impact of end-user demand and the impact of distributor purchasing dynamics on reported revenue.

Where growth rates are affected by changes in end-user demand, we refer to the impact of practice-level sales on growth. Where growth rates are affected by distributor purchasing dynamics, we refer to the impact of changes in distributors’ inventories on growth. If during the current year, distributors’ inventories grew by less than those inventories grew in the comparable period of the prior year, then changes in distributors’ inventories have a negative impact on our reported sales growth in the current period. Conversely, if during the current year, distributors’ inventories grew by more than those inventories grew in the comparable period of the prior year, then changes in distributors’ inventories have a positive impact on our reported sales growth in the current period.

At the end of a quarter, we believe that our U.S. CAG distributors typically hold inventory equivalent to approximately four weeks of our anticipated end-user demand for instrument consumables and rapid assay products.

Currency Impact. For the three and nine months ended September 30, 2011, approximately 25% and 26%, respectively, of our revenue was derived from products manufactured in the U.S. and sold internationally in local currencies compared to 24% and 25% for the three and nine months ended September 30, 2010, respectively. Strengthening of the rate of exchange for the U.S. dollar relative to other currencies has a negative impact on our revenues derived in currencies other than the U.S. dollar and on profits of products manufactured in the U.S. and sold internationally, and a weakening of the U.S. dollar has the opposite effect. Similarly, to the extent that the U.S. dollar is stronger in current or future periods relative to the exchange rates in effect in the corresponding prior periods, our growth rate will be negatively affected. The impacts of foreign currency denominated operating expenses and foreign currency denominated supply contracts partly offset this exposure.

The impact on revenue from changes in foreign currency exchange rates is a non-U.S. GAAP financial measure, which is a numerical measure the components of which do not align with the most directly comparable measure calculated and presented in accordance with U.S. GAAP. This particular measure is calculated by applying the differences between the average exchange rates during the current year period and the comparable previous year period to foreign currency denominated revenues for the current year period.

During the three months ended September 30, 2011, compared to the three months ended September 30, 2010, changes in foreign currency exchange rates increased total company revenue by approximately $9.5 million, due primarily to the weakening of the U.S. dollar against the Euro and, to a lesser extent, Australian dollar, Canadian dollar, Japanese yen, Swiss franc and British pound.

During the nine months ended September 30, 2011, compared to the nine months ended September 30, 2010, changes in foreign currency exchange rates increased total company revenue by approximately $26.2 million, due primarily to the weakening of the U.S. dollar against the Euro, Australian dollar and, to a lesser extent, Japanese yen, Canadian dollar, British pound and Swiss franc.

These changes in foreign currency exchange rates impacted the revenues generated by each of our individual operating segments in a manner similar to the impact on the company as a whole.

Effect of Economic Conditions. Demand for many of our products and services has been negatively affected by economic conditions since approximately mid-2008. In our CAG segment, we believe that low economic growth and relatively high unemployment have led to negative or cautious consumer sentiment, which has affected the number of patient visits to veterinary clinics. Since the beginning of the economic slowdown, patient visits have been flat to slightly down in each year-over-year period. We continued to observe this trend during the three and nine months ended September 30, 2011 relative to the same periods in 2010. We believe the essentially flat patient visits have had a slightly negative impact on the growth rate of sales of rapid assay tests, instrument consumables and reference laboratory diagnostic and consulting services. In addition, we believe the rate of growth of sales of our instruments and digital radiography systems, which are larger capital purchases for veterinarians, has been negatively affected by continued caution among veterinarians regarding economic conditions. Weaker economic conditions have also caused our customers to remain sensitive to the pricing of our products and services resulting in lower growth due to limited price increases for certain products.

We also believe that current economic conditions have affected purchasing decisions of our Water business customers. Lower water testing volumes have resulted from a decline in discretionary testing and a decline in mandated testing as a result of lower home and commercial construction.

We believe that the diversity and innovative nature of our products and services, and the geographic diversity of our markets, have and will continue to partially mitigate the effects of the slow economic growth and negative consumer sentiment. However, until we see improvements in broad factors that measure the economic climate both in the U.S. and Europe, we expect that our growth rates will continue to be negatively affected.

■ Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates. We base our estimates on historical experience and on various assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. The significant accounting policies used in preparation of these condensed consolidated financial statements for the three and nine months ended September 30, 2011 are consistent with those discussed in Note 3 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2010. The critical accounting policies and the significant judgments and estimates used in the preparation of our condensed consolidated financial statements for the three and nine months ended September 30, 2011 are consistent with those discussed in our Annual Report on Form 10-K for the year ended December 31, 2010 in the section under the heading “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates.”

(1)

The percentage change from currency is a non-U.S. GAAP measure. It represents the percentage change in revenue resulting from the difference between the average exchange rates during the three months ended September 30, 2011 and the same period of the prior year applied to foreign currency denominated revenues for the three months ended September 30, 2011.

(2)	The percentage change from acquisitions is a non-U.S. GAAP measure. It represents the percentage change in revenue during the three months ended September 30, 2011 compared to the three months ended September 30, 2010 attributed to incremental revenues from acquisitions subsequent to June 30, 2010.

(3)	Organic revenue growth is a non-U.S. GAAP measure and represents the percentage change in revenue during the three months ended September 30, 2011 compared to the three months ended September 30, 2010 net of acquisitions and the effect of changes in foreign currency exchange rates.

The following revenue analysis and discussion reports on organic revenue growth. Organic revenue growth should be considered in addition to, and not as a replacement for or as superior to, revenues reported in accordance with U.S. GAAP, and may not be comparable to similarly titled measures reported by other companies. Management believes that reporting organic revenue growth provides useful information to investors by facilitating easier comparisons of our revenue performance with prior and future periods and to our peers. We exclude the effect of changes in foreign currency exchange rates because changes in foreign currency exchange rates are not under management’s control, are subject to volatility and can obscure underlying business trends. We exclude the effect of acquisitions and divestitures because the nature, size and number of acquisitions can vary dramatically from period to period and therefore can also obscure underlying business trends.

(2)	The percentage change from acquisitions is a non-U.S. GAAP measure. It represents the percentage change in revenue during the three months ended September 30, 2011 compared to the three months ended September 30, 2010 attributed to incremental revenues from acquisitions subsequent to June 30, 2010.

(3)	Organic revenue growth is a non-U.S. GAAP measure and represents the percentage change in revenue during the three months ended September 30, 2011 compared to the three months ended September 30, 2010 net of acquisitions and the effect of changes in foreign currency exchange rates.

Instruments revenue was $24.8 million and $21.1 million for the three months ended September 30, 2011 and 2010, respectively. Consumables revenue was $63.3 million and $57.0 million for the three months ended September 30, 2011 and 2010, respectively. Instrument service and accessories revenue was $11.2 million and $10.2 million for the three months ended September 30, 2011 and 2010, respectively. The remaining sources of revenue are not significant to overall instruments and consumables revenue. Instruments revenue growth was due primarily to higher sales volumes of our Catalyst Dx® instrument and our ProCyte Dx® instrument, the hematology analyzer that we began shipping during the third quarter of 2010. These favorable factors were partly offset by lower average unit sales prices driven by discounts associated with customer purchase programs. Consumables revenue growth was due primarily to higher sales of consumables used with our Catalyst Dx® instrument, partly offset by lower sales of consumables used with our VetTest® chemistry instrument as customers continue to upgrade from our VetTest® instrument to our Catalyst Dx® instrument. Higher sales of consumables used with our ProCyte Dx® instrument also contributed to the increase in consumables revenue. Service and accessories revenue growth was primarily a result of the increase in our active installed base of instruments. The impact of changes in distributors’ inventory levels reduced instruments and consumables revenue growth by less than 1%.

The slight decrease in rapid assay revenue was due primarily to the unfavorable impact of changes in distributors’ inventory levels, which reduced revenue growth by 3%. This unfavorable impact was substantially offset by an increase in U.S. practice-level sales of our canine heartworm and canine combination test products and, to a lesser extent, sales of our feline pancreatitis test product, which we began shipping during the second quarter of 2011.

The increase in reference laboratory diagnostic and consulting services revenue resulted primarily from the impact of higher testing volume and, to a lesser extent, price increases. Higher testing volume was driven by the acquisition of new customers due in part to geographic expansion and customer acquisition related programs in which customers are provided incentives in the form of IDEXX Points or cash in exchange for agreements to purchase services in future periods.

The increase in practice management systems and digital radiography revenue resulted primarily from higher service and support revenue and an increase in sales volumes of our practice management systems. These favorable factors were partly offset by an increase in placements of digital radiography systems under customer acquisition related programs for which the related revenue is recognized over future periods.

Water. The increase in Water revenue resulted primarily from higher sales volumes of Colilert® test products, partly offset by the unfavorable impact of higher relative sales of Colilert® test products in geographies where products are sold at lower average unit sales prices.

Livestock and Poultry Diagnostics. The increase in LPD revenue resulted primarily from higher sales volumes of certain bovine tests and, to a lesser extent, higher sales volumes of certain poultry tests. The increased sales volume of certain bovine tests was due, in part, to sales in Germany where we have won several government tenders for testing in connection with a country-wide eradication program for a virus impacting beef and dairy production yields. These increases were partly offset by lower sales volumes of certain swine tests and, to a lesser extent, lower sales of Bovine Spongiform Encephalopathy (“BSE” or “mad cow disease”) tests resulting from the changes in European Union BSE testing requirements. Effective July 1, 2011, the age at which healthy cattle to be slaughtered are required to be tested for BSE in the European Union was increased from 48 months to 72 months, which is reducing the population of cattle tested for this disease.

Other. The increase in Other revenue was primarily attributable to higher sales volumes in our OPTI Medical line of business, partly offset by lower sales volumes of our Dairy SNAP® residue test for the detection of melamine. Increased sales volume in our OPTI Medical line of business was driven by sales of consumables used with our instruments and, to a lesser extent, by sales of instruments.

Gross Profit

Total Company. The following table presents gross profit and gross profit percentages by operating segment:

For the Three Months Ended September 30,
Gross Profit (dollars in thousands)	2011		Percent of Revenue			2010			Percent of Revenue			Dollar Change			Percentage Change

CAG	$	126,048		50.8	%	$	113,924			51.1	%	$	12,124			10.6	%
Water		14,317		66.1	%		12,542			62.6	%		1,775			14.2	%
LPD		13,666		66.1	%		11,812			67.6	%		1,854			15.7	%
Other		4,009		38.0	%		4,104			44.6	%		(95	)		(2.3	%)
Unallocated Amounts		627		N/A			(175	)		N/A			802			N/A
Total Company	$	158,667		52.7	%	$	142,207			52.7	%	$	16,460			11.6	%

Companion Animal Group. Gross profit for CAG increased due to higher sales, partly offset by a slight decrease in the gross profit percentage. The decrease in gross profit percentage was due primarily to increased manufacturing costs, higher relative sales of certain of our VetLab® instruments that yield lower margins compared to other CAG products and services and lower average unit sales prices due, in part, to discounts associated with customer purchase programs. Increased manufacturing costs were driven, in part, by lower production volumes associated with certain of our VetLab® consumables during the three months ended September 30, 2011 compared to the same period of the prior year. These unfavorable factors were partly offset by lower costs of service.

Water. Gross profit for Water increased due to higher sales and an increase in the gross profit percentage to 66% from 63%. The increase in the gross profit percentage was due primarily to reductions in certain manufacturing costs that we do not expect to continue at this level and, to a lesser extent, higher relative sales of our Colilert® products that yield higher margins. These favorable impacts were partly offset by lower average unit sales prices of our Colilert® products and, to a lesser extent, increased freight costs as a result of rising fuel surcharges.

Livestock and Poultry Diagnostics. Gross profit for LPD increased as higher sales were partly offset by a decrease in the gross profit percentage to 66% from 68%. The decrease in the gross profit percentage was due primarily to lower average unit sales prices of our BSE tests and increased freight costs as a result of rising fuel surcharges.

Other. Gross profit for Other operating units decreased due to a decrease in the gross profit percentage to 38% from 45%, partly offset by higher sales. The decrease in the gross profit percentage was due primarily to increased manufacturing costs in our OPTI Medical line of business that we do not expect to continue and higher relative sales of products that yield lower gross margins. These unfavorable factors were partly offset by the favorable impact of currency driven by the net favorable impact of changes in foreign currency exchange rates.

Unallocated Amounts. Gross profit for Unallocated Amounts increased $0.8 million to $0.6 million due primarily to a decrease in certain personnel-related costs, partly offset by the unfavorable impact of certain manufacturing costs. See the subsection above titled “Business Overview and Trends” for further information regarding the nature of these manufacturing costs. Also as discussed in subsection above titled “Business Overview and Trends” under the heading “Item 2. Management’s Discussion and Analysis of Financial Conditions and Results of Operations” in this Quarterly Report on Form 10-Q, we estimate certain personnel-related costs and allocate the estimated expenses to the operating segments. This allocation differs from actual expense and consequently yields a difference that is reported under the caption “Unallocated Amounts.” The decrease in certain personnel-related costs for Unallocated Amounts is due primarily to lower self-insured health care costs during the three months ended September 30, 2011 compared to the same period of the prior year.
