NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 

(Unaudited)

NOTE 1. BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION 

The accompanying unaudited condensed consolidated financial statements of IDEXX Laboratories, Inc. and its subsidiaries have been prepared in accordance with 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 this Quarterly Report on Form 10-Q. Unless the context requires otherwise, references in this Quarterly Report on Form 10-Q to “IDEXX,” the “Company,” “we,” “our,” or “us” refer to IDEXX Laboratories, Inc. and its subsidiaries.

The accompanying unaudited condensed consolidated financial statements include the accounts of IDEXX Laboratories, Inc. and our wholly-owned and majority-owned subsidiaries. We do not have any variable interest entities for which we are the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.

The accompanying unaudited condensed consolidated financial statements reflect, in the opinion of our management, all adjustments necessary for a fair statement of our financial position and results of operations. All such adjustments are of a recurring nature. The condensed consolidated balance sheet data as of December 31, 2022, 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 six months ended June 30, 2023, are not necessarily indicative of the results to be expected for the full year or any future period. These unaudited condensed consolidated financial statements should be read in conjunction with this Quarterly Report on Form 10-Q for the quarter ended June 30, 2023, and our Annual Report on Form 10-K for the year ended December 31, 2022, (the “2022 Annual Report”) filed with the SEC.

The preparation of our condensed consolidated financial statements requires us to make estimates, judgments, and assumptions that may affect the reported amounts of assets, liabilities, equity, revenues, and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis we evaluate our estimates, judgments, and methodologies. We base our estimates on historical experience and on various other assumptions that we believe are reasonable, the results of which form the basis for making judgments about the carrying values of assets, liabilities, and equity, and the amount of revenues and expenses.

We have included certain terms and abbreviations used throughout this Quarterly Report on Form 10-Q in the “Glossary of Terms and Selected Abbreviations.”

NOTE 2. ACCOUNTING POLICIES  

Significant Accounting Policies

The significant accounting policies used in preparation of these unaudited condensed consolidated financial statements as of and for the three and six months ended June 30, 2023, are consistent with those discussed in “Note 2. Summary of Significant Accounting Policies” to the consolidated financial statements in our 2022 Annual Report, and as updated below.

Accounts Payable - Supplier Financing Program

We have an agreement with a third party to provide a supplier finance program, which facilitates participating suppliers’ ability to finance payment obligations from us with a designated third-party financial institution. Participating suppliers may, at their sole discretion, make offers to finance one or more of our payment obligations prior to their scheduled due dates at a discounted price. Our obligations to our suppliers, including amounts due and scheduled payment dates, are not impacted by suppliers’ decisions to finance amounts under these arrangements. The terms of payments are in-line with the terms of our trade payables. Activity related to the obligations is presented within operating activities on the unaudited consolidated statements of cash flows. The changes in our outstanding payment obligations under this arrangement, which are included in accounts payable on the unaudited condensed consolidated balance sheets, are as follows:

New Accounting Pronouncements Adopted

We adopted ASU 2022-04, “Liabilities - Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations,” as of January 1, 2023, which adds certain disclosure requirements for a buyer in a supplier finance program. The amendments in this update require that a buyer in a supplier finance program discloses sufficient information about the program to allow a user of financial statements to understand the program's nature, activity during the period, changes from period to period, and potential magnitude.

We adopted ASU 2021-08, “Business Combinations (Topic 805): Accounting for Acquired Contract Assets and Contract Liabilities,” as of January 1, 2023. ASU 2021-08 is intended to improve comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of and after a business combination by providing consistent recognition guidance. The adoption of ASU 2021-08 did not have a material impact on our unaudited condensed consolidated financial statements.

NOTE 3. REVENUE RECOGNITION

Our revenue is recognized when, or as, performance obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to a customer. We exclude sales, use, value-added, and other taxes we collect on behalf of third parties from revenue. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or services to a customer. To accurately present the consideration received in exchange for promised products or services, we apply the five-step model outlined below:

1.Identification of a contract or agreement with a customer

2.Identification of our performance obligations in the contract or agreement

3.Determination of the transaction price

4.Allocation of the transaction price to the performance obligations

5.Recognition of revenue when, or as, we satisfy a performance obligation        

9

We enter into contracts where customers purchase combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. The timing of revenue recognition, billings, and cash collections results in accounts receivable, lease receivables, and contract assets as a result of revenue recognized in advance of billings, and contract liabilities or deferred revenue as a result of receiving consideration in advance of revenue recognition within our unaudited condensed consolidated balance sheet. Our general payment terms range from 30 to 60 days, with exceptions in certain geographies.

Contracts may be amended to account for changes in contract specifications and requirements. Contract modifications exist when the amendment either creates new, or changes existing, enforceable rights and obligations. A modification is considered to be a separate contract, and revenue is recognized prospectively, when the modification creates new performance obligations to deliver additional goods or services and the related increase in consideration approximates the standalone selling price for the additional goods or services. If a contract modification does not create a new performance obligation to deliver new goods and/or services but the goods and/or services to be delivered after the contract modification date are distinct from the goods and/or services delivered on or before the contract modification date, then this contract modification is not accounted for as a separate contract, and we account for the goods and/or services to be delivered after the contract modification date prospectively. We account for a contract modification as if it were a part of the existing contract if the remaining goods or services are not distinct and, therefore, form part of a single performance obligation that is partially satisfied at the date of the contract modification. The effect that these contract modifications have on the transaction price, and on our measure of progress toward complete satisfaction of the performance obligation, is recognized as an adjustment to revenue at the date of the contract modification, with the adjustment to revenue made on a cumulative catch-up basis.

Below is a listing of our major categories of revenue for our products and services:

Diagnostic Products and Accessories. Diagnostic products and accessories revenues, including IDEXX VetLab® consumables and accessories, rapid assay, LPD, Water, and OPTI testing products, are predominantly recognized and invoiced at the time of shipment, which is when the customer obtains control of the product based on legal title transfer and we have the right to payment. We also provide customers with certain consumables that are recognized upon utilization by the customer, which is when we have the right to payment and the risks and rewards of ownership transfer. Shipping costs reimbursed by the customer are included in revenue and cost of sales. As a practical expedient, we do not account for shipping activities as a separate performance obligation.

Laboratory Diagnostic and Consulting Services. Laboratory diagnostic and consulting services revenues are recognized and invoiced when the laboratory diagnostic service is performed.

Instruments, Software and Systems. CAG Diagnostics capital instruments, veterinary software, and diagnostic imaging systems revenues are recognized and invoiced when the customer obtains control of the products based on legal title transfer and we have the right to payment, which generally occurs at the time of installation and customer acceptance. Our instruments, software, and systems are often included in one of our significant customer programs, as further described below. For veterinary software systems that include multiple performance obligations, such as perpetual software licenses and computer hardware, we allocate revenue to each performance obligation based on estimates of the price that we would charge the customer for each promised product or service if it were sold on a standalone basis.

Lease Revenue. Revenues from instrument rental agreements and reagent rental programs are recognized either as operating leases on a ratable basis over the term of the agreement or as sales-type leases at the time of installation and customer acceptance. Customers typically pay for the right to use instruments under rental agreements in equal monthly amounts over the term of the rental agreement. Our reagent rental programs provide our customers the right to use our instruments upon entering into multi-year agreements to purchase annual minimum amounts of consumables. These types of agreements include an embedded lease for the right to use our instruments. For some agreements, the customers are provided with the right to purchase the instrument at the end of the lease term. Lease revenues from these agreements are presented in product revenue on our unaudited condensed consolidated income statement. Lease revenue was approximately $5.5 million and $10.0 million for the three and six months ended June 30, 2023, respectively, as compared to $4.9 million and $9.9 million for the three and six months ended June 30, 2022, respectively, including both operating leases and sales-type leases under ASC 842, Leases, for leases entered into after January 1, 2019, and ASC 840, “Leases,” for leases entered into prior to 2019. Refer to below for revenue recognition under our reagent rental programs.

Extended Warranties and Post-Contract Support. CAG Diagnostics capital instruments and diagnostic imaging systems extended warranties typically provide customers with continued coverage for a period of one to five years beyond the first-year standard warranty. Customers can either pay in full for the extended warranty at the time of instrument or system

10

purchase or can be billed on a quarterly basis over the term of the contract. We recognize revenue associated with extended warranties over time on a ratable basis using a time-elapsed measure of performance over the contract term, which approximates the expected timing in which applicable services are performed.

Veterinary software post-contract support provides customers with access to technical support when and as needed through access to call centers and online customer assistance. Post-contract support contracts typically have a term of 12 months and customers are billed for post-contract support in equal quarterly amounts over the term. We recognize revenue for post-contract support services over time on a ratable basis using a time-elapsed measure of performance over the contract term, which approximates the expected timing in which applicable services are performed.

On December 31, 2022, our deferred revenue related to extended warranties and post-contract support was $26.4 million, of which approximately $1.8 million and $16.9 million were recognized during the three and six months ended June 30, 2023, respectively. Furthermore, as a result of new agreements, our deferred revenue related to extended warranties and post-contract support was $25.9 million as of June 30, 2023. We do not disclose information about remaining performance obligations that are part of contracts with an original expected duration of one year or less and do not adjust for the effect of the financing components when the period between customer payment and revenue recognition is one year or less. Deferred revenue related to extended warranties and post-contract support with an original duration of more than one year was $10.0 million as of June 30, 2023, of which approximately 24%, 37%, 21%, 9%, and 9% are expected to be recognized during the remainder of 2023, the full years 2024, 2025, 2026, and thereafter, respectively. Additionally, we have determined these agreements do not include a significant financing component.

SaaS Subscriptions. We offer a variety of veterinary software and diagnostic imaging SaaS subscriptions including ezyVet®, Animana®, Neo®, Cornerstone® Cloud, Pet Health Network® Pro, Petly® Plans, Web PACS, rVetLink®, and Smart Flow™. We recognize revenue for our SaaS subscriptions over time on a ratable basis over the contract term, beginning on the date our service is made available to the customer. Our subscription contracts vary in term from monthly to two years. Customers typically pay for our subscription contracts in equal monthly amounts over the term of the agreement. Deferred revenue related to our SaaS subscriptions is not material.

Contracts with Multiple Performance Obligations. We enter into contracts with multiple performance obligations where customers purchase a combination of IDEXX products and services. Determining whether products and services are considered distinct performance obligations that should be accounted for separately requires significant judgment. We determine the transaction price for a contract based on the total consideration we expect to receive in exchange for the transferred goods or services. To the extent the transaction price includes variable consideration, such as volume rebates or expected price adjustments, we apply judgment in constraining the estimated variable consideration due to factors that may cause reversal of revenue recognized. We evaluate constraints based on our historical and projected experience with similar customer contracts.

We allocate revenue to each performance obligation in proportion to the relative standalone selling prices, and recognize revenue when transfer of the related goods or services has occurred for each obligation. We utilize the observable standalone selling price when available, which represents the price charged for the promised product or service when sold separately. When standalone selling prices for our products or services are not directly observable, we determine the standalone selling prices using relevant information available and apply suitable estimation methods including, but not limited to, the cost plus a margin approach. We recognize revenue as each performance obligation is satisfied, either at a point in time or over time, as described in the revenue categories above. We do not disclose information about remaining performance obligations that are part of contracts with an original expected duration of one year or less.

The following customer programs represent our most significant customer contracts that contain multiple performance obligations:

Customer Commitment Programs. We offer customer incentives upon entering into multi-year agreements to purchase annual minimum amounts of products and services.

Up-Front Customer Loyalty Programs. Our up-front loyalty programs provide customers with incentives in the form of cash payments or IDEXX Points upon entering into multi-year agreements to purchase annual minimum amounts of future products or services. If a customer breaches their agreement, they are required to refund all or a portion of the up-front cash or IDEXX Points, or make other repayments, remedial actions, or both. Up-front incentives to customers in the form of cash or IDEXX Points are not made in exchange for distinct goods or services and are capitalized as customer acquisition costs within other current and long-term assets, which are subsequently recognized as a reduction to revenue over the term of

11

the customer agreement. If these up-front incentives are subsequently utilized to purchase instruments, we allocate total consideration, including future committed purchases less up-front incentives and estimates of expected price adjustments, based on relative standalone selling prices to identified performance obligations and recognize instrument revenue and cost at the time of installation and customer acceptance. To the extent invoiced instrument revenue exceeds recognized instrument revenue, we record deferred revenue as a contract liability, which is subsequently recognized upon the purchase of products and services over the term of the contract. We have determined these agreements do not include a significant financing component. Differences between estimated and actual customer purchases may impact the timing and amount of revenue recognition.

On December 31, 2022, our capitalized customer acquisition costs were $158.0 million, of which approximately $13.0 million and $26.4 million were recognized as a reduction of revenue during the three and six months ended June 30, 2023, respectively. Furthermore, as a result of new up-front customer loyalty payments, net of subsequent recognition, our capitalized customer acquisition costs were $162.6 million as of June 30, 2023. We monitor customer purchases over the term of their agreement to assess the realizability of our capitalized customer acquisition costs and review estimates of variable consideration. Impairments and revenue adjustments that relate to performance obligations satisfied in prior periods, including cumulative catch-up adjustments to revenue arising from contract modifications during the three and six months ended June 30, 2023, were not material.

Volume Commitment Programs. Our volume commitment programs, such as our IDEXX 360 program, provide customers with free or discounted instruments or systems upon entering into multi-year agreements to purchase annual minimum amounts of products and services. We allocate total consideration, including future committed purchases and expected price adjustments, based on relative standalone selling prices to identified performance obligations and recognize instrument revenue and cost at the time of installation and customer acceptance in advance of billing the customer, which is also when the customer obtains control of the instrument based on legal title transfer. Our right to future consideration related to instrument revenue is recorded as a contract asset within other current and long-term assets. The contract asset is transferred to accounts receivable when customers are billed for future products and services over the term of the contract. We have determined these agreements do not include a significant financing component. Differences between estimated and actual customer purchases may impact the timing and amount of revenue recognition.

On December 31, 2022, our volume commitment contract assets were $190.8 million, of which approximately $10.9 million and $22.0 million were reclassified to accounts receivable when customers were billed for related products and services during the three and six months ended June 30, 2023, respectively. Furthermore, as a result of new placements under volume commitment programs, net of subsequent amounts reclassified to accounts receivable, and allowances established for credit losses, our volume commitment contract assets were $207.9 million as of June 30, 2023. We monitor customer purchases over the term of their agreement to assess the realizability of our contract assets and review estimates of variable consideration. Impairments and revenue adjustments that relate to performance obligations satisfied in prior periods, including cumulative catch-up adjustments to revenue arising from contract modifications during the three and six months ended June 30, 2023, were not material.

For our up-front customer loyalty and volume commitment programs, we estimate future revenues related to multi-year agreements to be approximately $3.0 billion, of which approximately 15%, 27%, 22%, 18%, and 18% are expected to be recognized during the remainder of 2023, the full years 2024, 2025, 2026, and thereafter, respectively. These future revenues relate to performance obligations not yet satisfied, for which customers have committed to future purchases, net of the expected revenue reductions from customer acquisition costs and expected price adjustments, and, as a result, are lower than stated contractual commitments by our customers.

Instrument Rebate Programs. Our instrument rebate programs require an instrument purchase and provide customers the opportunity to earn future rebates based on the volume of products and services they purchase over the term of the program. We account for the customer’s right to earn rebates on future purchases as a separate performance obligation and determine the standalone selling price based on an estimate of rebates the customer will earn over the term of the program. Total consideration allocated to identified performance obligations is limited to goods and services that the customer is presently obligated to purchase and does not include estimates of future purchases that are optional. We allocate total consideration to identified performance obligations, including the customer’s right to earn rebates on future purchases, which is deferred and subsequently recognized upon the purchase of products and services, partly offsetting rebates as they are earned.

12

On December 31, 2022, our deferred revenue related to instrument rebate programs was $25.6 million, of which approximately $2.4 million and $5.0 million were recognized when customers purchased eligible products and services and earned rebates during the three and six months ended June 30, 2023, respectively. Furthermore, as a result of new instrument purchases under rebate programs, net of subsequent recognition, our deferred revenue was $23.7 million as of June 30, 2023, of which approximately 19%, 29%, 22%, 15%, and 15% are expected to be recognized during the remainder of 2023, the full years 2024, 2025, 2026, and thereafter, respectively.

Reagent Rental Programs. Our reagent rental programs provide our customers the right to use our instruments upon entering into multi-year agreements to purchase annual minimum amounts of consumables. These types of agreements include an embedded lease for the right to use our instrument, and we determine the amount of lease revenue allocated to the instrument based on relative standalone selling prices. We evaluate the terms of these embedded leases to determine classification as either a sales-type lease or an operating lease.

Sales-type Reagent Rental Programs. Our reagent rental programs that effectively transfer control of instruments to our customers are classified as sales-type leases, and we recognize instrument revenue and cost in advance of billing the customer, at the time of installation and customer acceptance. Our right to future consideration related to instrument revenue is recorded as a lease receivable within other current and long-term assets, and is transferred to accounts receivable when customers are billed for future products and services over the term of the contract. On December 31, 2022, our lease receivable assets were $18.4 million, of which approximately $1.1 million and $2.2 million were reclassified to accounts receivable when customers were billed for related products and services during the three and six months ended June 30, 2023, respectively. Furthermore, as a result of new placements under sales-type reagent rental programs, net of subsequent amounts reclassified to accounts receivable, and allowances established for credit losses, our lease receivable assets were $19.7 million as of June 30, 2023. The impacts of discounting and unearned income as of June 30, 2023 were not material. Profit and loss recognized at the commencement date and interest income during the three and six months ended June 30, 2023, were not material. We monitor customer purchases over the term of their agreement to assess the realizability of our lease receivable assets. Impairments during the three and six months ended June 30, 2023 were not material.

Operating-type Reagent Rental Programs. Our reagent rental programs that do not effectively transfer control of instruments to our customers are classified as operating leases, and we recognize instrument revenue and costs ratably over the term of the agreement. The cost of the instrument is capitalized within property and equipment. During the three and six months ended June 30, 2023, we transferred instruments of $4.8 million and $8.6 million, respectively, as compared to $4.6 million and $7.6 million for the three and six months ended June 30, 2022, respectively, from inventory to property and equipment.

We estimate future revenue to be recognized related to our reagent rental programs of approximately $47.8 million, of which approximately 13%, 25%, 21%, 16%, and 25% are expected to be recognized during the remainder of 2023, the full years 2024, 2025, 2026, and thereafter, respectively. These future revenues relate to performance obligations not yet satisfied for which customers have committed to future purchases, net of any expected price adjustments, and, as a result, may be lower than stated contractual commitments by our customers.

Other Customer Incentive Programs. Certain agreements with customers include discounts or rebates on the sale of products and services applied retrospectively, such as volume rebates achieved by purchasing a specified purchase threshold of goods and services. We account for these discounts as variable consideration and estimate the likelihood of a customer meeting the threshold in order to determine the transaction price using the most predictive approach. We typically use the most-likely-amount method for incentives that are offered to individual customers and the expected-value method for programs that are offered to a broad group of customers. Revenue adjustments that relate to performance obligations satisfied in prior periods, including cumulative catch-up adjustment to revenue arising from contract modifications, during the three and six months ended June 30, 2023, were not material. Refund obligations related to customer incentive programs are recorded in accrued liabilities for the actual issuance of incentives, incentives earned but not yet issued, and estimates of incentives to be earned in the future.

Program Combinations. At times, we combine elements of our significant customer programs within a single customer contract. We separate each significant program element and include the contract assets, customer acquisition costs, deferred revenues, and estimated future revenues within the most relevant program disclosures above. Each customer contract is presented as a net contract asset or net contract liability on our unaudited condensed consolidated balance sheet.

13

IDEXX Points. IDEXX Points may be applied to trade receivables due to us, converted to cash, or applied against the purchase price of IDEXX products and services. We consider IDEXX Points equivalent to cash. IDEXX Points that have not yet been used by customers are included in accrued liabilities until utilized or expired. Breakage is not material because customers can apply IDEXX Points to trade receivables at any time.

Accounts Receivable. We recognize revenue when it is probable that we will collect substantially all of the consideration to which we will be entitled, based on the customer’s intent and ability to pay the promised consideration. We apply judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the customer. Concentrations of credit risk with respect to accounts receivable are limited due to the large number of customers that purchase our products and services, and we have no significant customers that accounted for greater than 10% of our consolidated revenues during the three and six months ended June 30, 2023.

Disaggregated Revenues. We present disaggregated revenue for our CAG segment based on major product and service categories. Our Water segment is comprised of a single major product category. Although our LPD segment does not meet the quantitative requirements to be reported as a separate segment, we believe it is important to disaggregate these revenues as a major product and service category separately from our Other reportable segment given its distinct markets, and therefore we have elected to report LPD as a reportable segment.

The following table presents disaggregated revenue by major product and service categories:

(in thousands)	For the Three Months Ended June 30,				For the Six Months Ended June 30,

Total revenue	$	943,630	$	860,546	$	1,843,825	$	1,697,095

Costs to Obtain a Contract. We capitalize sales commissions, and the related fringe benefits earned by our sales force when considered incremental, and recoverable costs of obtaining a contract. Our contracts include performance obligations related to various goods and services, some of which are satisfied at a point in time and others over time. Commission costs related to performance obligations satisfied at a point in time are expensed at the time of sale, which is when revenue is recognized. Commission costs related to long-term service contracts and performance obligations satisfied over time, including extended warranties and SaaS subscriptions, are deferred and recognized on a systematic basis that is consistent with the

14

transfer of the goods or services to which the asset relates. We apply judgment in estimating the amortization period, which ranges from 3 to 7 years, by taking into consideration our customer contract terms, history of renewals, and expected length of customer relationship, as well as the useful life of the underlying technology and products. Amortization expense is included in sales and marketing expenses in the accompanying unaudited condensed consolidated statements of income. Deferred commission costs are periodically reviewed for impairment.

On December 31, 2022, our deferred commission costs, included within other assets, were $19.2 million, of which approximately $1.7 million and $3.4 million of commission expense was recognized during the three and six months ended, respectively. June 30, 2023. Furthermore, as a result of commissions related to new extended warranties and SaaS subscriptions, net of subsequent recognition, our deferred commission costs were $19.5 million as of June 30, 2023. Impairments of deferred commission costs during the three and six months ended June 30, 2023, were not material.

NOTE 4. ACQUISITIONS, ASSET PURCHASES AND INVESTMENTS

We believe that our acquisitions of businesses and other assets enhance our existing businesses by either expanding our geographic range, customer base, or existing product and service lines. From time to time we may acquire small reference laboratories or radiology practices that we account for as either asset purchases or business combinations.

Asset Purchases and Investments

During the first quarter of 2022 we made a $10.0 million payment for a perpetual intellectual property license, which will be amortized over 10 years. The related amortization expense is recorded in our CAG segment.

During the second quarter of 2022, we entered into two discrete arrangements to license intellectual property for which we paid $65.0 million over the course of the 2022, and accrued $15.0 million in subsequent payments, all of which was charged to research and development expense. The $15.0 million milestone payment was made in the first quarter of 2023. These two arrangements were treated as asset acquisitions under U.S. GAAP and resulted in the full amount being expensed to research and development expense as in-process research and development costs with no alternative future use. The acquisition of these licensing arrangements supports new instrument platform advancements.

During the second quarter of 2022 we purchased $25.0 million of preferred shares for a noncontrolling minority interest in one of the entities with which we have a license agreement. We elected to measure the investment as an equity security investment, under ASC 321, “Investment - Equity Securities,” and recorded the investment at cost.

Business Combinations

During the third quarter of 2022, we acquired the assets of an international water testing company located in Canada for approximately $12.8 million in cash, including a holdback of approximately $1.3 million. This acquisition expands our product offering in the Water segment. The fair values of the assets and liabilities acquired consists of technology intangibles of approximately $3.4 million, with a life of 10 years; customer relationship intangibles of approximately $1.2 million, with a life of 10 years; approximately $6.9 million of goodwill, representing synergies with our Water testing portfolio; and approximately $1.3 million of tangible assets, including inventory and accounts receivable. Goodwill related to this acquisition is expected to be deductible for tax purposes. Pro forma information has not been presented for this acquisition because such information is not material to the financial statements. The results of operations have been included in our Water segment since the acquisition date. The acquisition expenses were not material.

NOTE 5. SHARE-BASED COMPENSATION 

The fair value of options, restricted stock units, deferred stock units, and employee stock purchase rights awarded during the three and six months ended June 30, 2023, totaled $3.3 million and $60.6 million, respectively, as compared to $4.4 million and $55.4 million for the three and six months ended June 30, 2022, respectively. The total unrecognized compensation expense, net of estimated forfeitures, for unvested share-based compensation awards outstanding as of June 30, 2023, was $94.3 million, which will be recognized over a weighted average period of approximately 1.7 years. During the three and six months ended June 30, 2023, we recognized expenses of $15.4 million and $29.3 million, respectively, as compared to $12.3 million and $23.5 million for the three and six months ended June 30, 2022, respectively, related to share-based compensation.

We determine the assumptions used in the valuation of option awards as of the date of grant. Differences in the expected stock price volatility, expected term, or risk-free interest rate may necessitate distinct valuation assumptions at each

15

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 or greater than 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 intention to pay such a dividend at this time; 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 Six Months Ended June 30,
	2023			2022
Expected stock price volatility	32		%	30		%
Expected term, in years	6.7			6.4
Risk-free interest rate	3.7		%	2.0		%
Weighted average fair value of options granted	$	201.37		$	167.25

NOTE 6. CREDIT LOSSES  

We are exposed to credit losses primarily through our sales of products and services to our customers. We maintain allowances for credit losses for potentially uncollectible receivables. We base our estimates on a detailed analysis of specific customer situations and a percentage of our accounts receivable by aging category. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current economic conditions.

Additional allowances may be required if either the financial condition of our customers were to deteriorate, or a strengthening U.S. dollar impacts the ability of foreign customers to make payments to us on their U.S. dollar-denominated purchases. We monitor our ongoing credit exposure through active review of counterparty balances against contract terms and due dates. Our activities include timely account reconciliations, dispute resolution, and payment confirmations. We may employ collection agencies and legal counsel to pursue recovery of defaulted receivables.

Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered. We may require collateralized asset support or a prepayment to mitigate credit risk. We do not have any off-balance sheet credit exposure related to our customers.

Accounts Receivable

The allowance for credit losses associated with accounts receivable was $9.8 million and $8.3 million as of June 30, 2023 and December 31, 2022, respectively. The amount of accounts receivable reflected on the balance sheet is net of this reserve. Based on an aging analysis, as of June 30, 2023, approximately 89% of our accounts receivable had not yet reached the invoice due date, and approximately 11% was considered past due, of which less than 1% was greater than 60 days past due. As of December 31, 2022, approximately 86% of our accounts receivable had not yet reached the invoice due date, and approximately 14% was considered past due, of which approximately 2% was greater than 60 days past due.

Contract assets and lease receivables

The allowance for credit losses associated with the contract assets and lease receivables was $6.0 million and $5.5 million as of June 30, 2023 and December 31, 2022, respectively. The assets reflected on the balance sheet are net of these reserves. Historically, we have experienced low credit loss rates on our customer commitment programs and lease receivables. We apply judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the customer.

NOTE 11. DEBT

Credit Facility

As of June 30, 2023, we had $264.0 million in outstanding borrowings under our Credit Facility, which consisted of $14.0 million drawn under our line of credit and a $250.0 million Term Loan, with a weighted average effective interest rate of 6.3%, excluding any impact of our interest rate swap. As of December 31, 2022, we had $579.0 million in outstanding borrowings under our Credit Facility, which consisted of $329.0 million drawn under our line of credit and a $250.0 million Term Loan, with a weighted average effective interest rate of 5.1%. As of June 30, 2023, we had a remaining borrowing availability of $984.5 million under our $1.25 billion Credit Facility. The funds available under the Credit Facility reflect a further reduction due to the issuance of letters of credit, which were issued primarily in connection with our workers’ compensation policy, for $1.5 million.

The applicable interest rate for the Credit Facility is calculated at a per annum rate equal to either (at our option) (1) a prime rate plus a margin ranging from 0.0% to 0.375% based on our consolidated leverage ratio, (2) an adjusted term SOFR rate, plus 0.10%, plus a margin ranging from 0.875% to 1.375% based on our consolidated leverage ratio, or (3) an adjusted daily simple SOFR rate, plus 0.10%, plus a margin ranging from 0.875% to 1.375% based on our consolidated leverage ratio. In March 2023 we entered into an interest rate swap contract to manage the economic effect of $250 million of variable interest borrowings under our Credit Facility. Refer to Note 19 for a discussion of our derivative instruments and hedging activity.

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 sole financial covenant is a consolidated leverage ratio test that requires our ratio of debt to earnings before interest, taxes, depreciation, amortization, and share-based compensation defined as the consolidated leverage ratio under the terms of the Credit Facility, not to exceed 3.5-to-1. At June 30, 2023 and December 31, 2022, we were in compliance with the covenants of the Credit Facility.

Senior Notes

The following describes all of our currently outstanding unsecured senior notes issued and sold in private placements (collectively, the “Senior Notes”) as of June 30, 2023:

The Senior Note Agreements contain affirmative, negative, and financial covenants customary for agreements of this type. The negative covenants include restrictions on liens, indebtedness of our subsidiaries, priority indebtedness, fundamental changes, investments, transactions with affiliates, and certain restrictive agreements. The sole financial covenant is a consolidated leverage ratio test that requires our ratio of debt to earnings before interest, taxes, depreciation, amortization, and share-based compensation, as defined in the Senior Note Agreements, not to exceed 3.5-to-1. At June 30, 2023 and December 31, 2022, we were in compliance with the covenants of the Senior Note Agreements.

NOTE 12. REPURCHASES OF COMMON STOCK

We primarily acquire shares by repurchases in the open market. However, we also acquire shares that are surrendered by employees in payment for the minimum required statutory withholding taxes due on the vesting of restricted stock units and the settlement of deferred stock units, otherwise referred to herein as employee surrenders. We issue shares of treasury stock upon the vesting of certain restricted stock units and upon the exercise of certain stock options. The number of shares of treasury stock issued during the three and six months ended June 30, 2023 and 2022 was not material.

The following is a summary of our open market common stock repurchases, reported on a trade date basis, and shares acquired through employee surrender:

(in thousands, except per share amounts)	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2023		2022		2023		2022
Shares repurchased in the open market	—		809		—		1,311

NOTE 13. INCOME TAXES 

Our effective income tax rate was 21.6% for the three months ended June 30, 2023, as compared to 22.9% for the three months ended June 30, 2022, and 20.8% for the six months ended June 30, 2023, as compared to 21.0% for the six months ended June 30, 2022. The decrease in our effective tax rate for the three and six months ended June 30, 2023, as compared to the same period in the prior year, was primarily driven by geographical income mix, partially offset by a decrease in the tax rate benefits related to share-based compensation.

The effective tax rate for the three and six months ended June 30, 2023, differed from the U.S. federal statutory tax rate of 21% primarily due to U.S. state income taxes, net of federal benefit, partially offset by taxes benefits from share-based compensation.

NOTE 15. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income attributable to our stockholders by the weighted average number of shares of common stock and vested deferred stock units outstanding during the year. 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 treasury stock method assumes that proceeds, including cash received from the exercise of employee stock options and the total unrecognized compensation expense for unvested share-based compensation awards, would be used to purchase our common stock at the average market price 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. Refer to Note 5 to the consolidated financial statements in our 2022 Annual Report for additional information regarding deferred stock units.

The following is a reconciliation of weighted average shares outstanding for basic and diluted earnings per share:

(in thousands)	For the Three Months Ended June 30,		For the Six Months Ended June 30,
	2023	2022	2023	2022
Shares outstanding for basic earnings per share	83,086	83,922	83,039	84,164
Shares outstanding for diluted earnings per share:

	83,983	84,858	83,980	85,222

Certain awards and 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 awards and options:

Weighted average number of shares underlying anti-dilutive options	397	284	371	248

NOTE 16. COMMITMENTS, CONTINGENCIES AND GUARANTEES

Commitments

Refer to “Note 8. Leases,” for more information regarding our lease commitments.

Contingencies

We are subject to claims that may arise in the ordinary course of business, including with respect to actual and threatened litigation and other matters. We accrue for loss contingencies when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. However, the results of legal actions cannot be predicted with certainty, and therefore our actual losses with respect to these contingencies could exceed our accruals. Except for the litigation matter described below, as of June 30, 2023, our accruals with respect to actual and threatened litigation were not material.

We are a defendant in an ongoing litigation matter involving an alleged breach of contract for underpayment of royalty payments made from 2004 through 2017 under an expired patent license agreement. The plaintiff has asserted a claim of approximately $50 million, inclusive of interest through June 30, 2020, alleging that the incorrect royalty provision was applied to certain licensed products and services throughout the agreement term and that royalties were also due on non-licensed diagnostic services that were provided concurrently with licensed services. The trial court previously ruled in favor of the plaintiff in this matter. The appellate court reversed the trial court’s decision, and the plaintiff has petitioned the state supreme court for review. While we believe the claim is without merit and continue to vigorously defend ourselves against the plaintiff’s allegations, litigation is inherently unpredictable, and there can be no assurance that we will prevail in this matter. During the third quarter of 2020, we established an accrual of $27.5 million related to this ongoing matter, which represents the amount of the contingent loss that we have determined to be probable and estimable. We have not made any adjustments to this accrual since it was established. The actual cost of resolving this matter may be higher or lower than the amount we have accrued.

From time to time, we have received notices alleging that our products infringe third-party proprietary rights, although we are not aware of any pending litigation with respect to such claims. Patent litigation frequently is complex and expensive, and the outcome of patent litigation can be difficult to predict. There can be no assurance that we will prevail in any infringement proceedings that may be commenced against us. If we lose any such litigation, we may be stopped from selling certain products and/or we may be required to pay damages as a result of the litigation.

Guarantees

We enter into agreements with third parties in the ordinary course of business under which we are obligated to indemnify such third parties for and against various risks and losses. The precise terms of such indemnities vary with the nature of the agreement. In many cases, we limit the maximum amount of our indemnification obligations, but in some cases, those obligations may be theoretically unlimited. We have not incurred material expenses in discharging any of these indemnification obligations and, based on our analysis of the nature of the risks involved, we believe that the fair value of potential indemnification under these agreements is minimal. Accordingly, we have recorded no liabilities for these obligations as of June 30, 2023 and December 31, 2022.

NOTE 17. SEGMENT REPORTING

We operate primarily through three business segments: Companion Animal Group (“CAG”), Water quality products (“Water”), and Livestock, Poultry and Dairy (“LPD”). CAG provides products and services for veterinarians and the biomedical research community, primarily related to diagnostics and information management. Water provides innovative testing solutions for the detection and quantification of various microbiological parameters in water. LPD provides diagnostic tests, services, and related instrumentation that are used to manage the health status of livestock and poultry, to improve producer efficiency, and to ensure the quality and safety of milk. Our Other operating segment combines and presents our human medical diagnostic business (“OPTI Medical”) with our out-licensing arrangements because they do not meet the quantitative or qualitative thresholds for reportable segments. OPTI Medical develops, manufactures, and distributes human medical diagnostic products and provides human medical diagnostic services. 

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker (“CODM”), or decision-making group, in deciding how to allocate resources and in assessing performance. Our CODM is our Chief Executive Officer. Our reportable segments include: CAG, Water, LPD, and Other. Assets are not allocated to segments for internal reporting purposes.

The following is a summary of segment performance:

NOTE 18. FAIR VALUE MEASUREMENTS 

U.S. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value.

We have certain financial assets and liabilities that are measured at fair value on a recurring basis, certain nonfinancial assets and liabilities that may be measured at fair value on a non-recurring basis, and certain financial assets and liabilities that are not measured at fair value in our unaudited condensed consolidated balance sheets but for which we disclose the fair value.

The fair value disclosures of these assets and liabilities are based on a three-level hierarchy, which is defined as follows: 

Level 1	Quoted prices in active markets for identical assets or liabilities that the entity can 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.
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.

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 transfers between Level 1 and Level 2, or transfers in or out of Level 3, of the fair value hierarchy during the three and six months ended June 30, 2023.

Our cross currency swap contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets. We measure the fair value of our cross currency swap contracts classified as derivative instruments using prevailing market conditions as of the close of business on each balance sheet date. The product of this calculation is then adjusted for counterparty risk.

Our foreign currency exchange contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets. We measure the fair value of our foreign currency exchange contracts classified as derivative instruments using an income approach, based on prevailing market forward rates less the contract rate multiplied by the notional amount. The product of this calculation is then adjusted for counterparty risk.

Our interest rate swap contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets. We measure the fair value of our interest rate swap contracts classified as derivative instruments using current market interest rates for debt issues with similar remaining years to maturity, adjusted for applicable credit risk.

The amounts outstanding under our unsecured credit facility (“Credit Facility”) and senior notes (“long-term debt”) are measured at carrying value in our unaudited condensed consolidated balance sheets though we disclose the fair value of these financial instruments. We determine the fair value of the amount outstanding under our Credit Facility and long-term debt using an income approach, utilizing a discounted cash flow analysis based on current market interest rates for debt issues with similar remaining years to maturity, adjusted for applicable credit risk. Our Credit Facility and long-term debt are valued using Level 2 inputs. The estimated fair value of our Credit Facility approximates its carrying value. The estimated fair value and carrying value of our long-term debt were $730.1 million and $772.2 million, respectively, as of June 30, 2023, and $725.6 million and $769.8 million, respectively, as of December 31, 2022.

(1)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. Refer to footnote (4) below for a discussion of the related deferred compensation liability. 

(2)Cross currency swaps and foreign currency exchange contracts are included within other current assets, other long-term assets, accrued liabilities, or other long-term liabilities depending on the gain (loss) position and anticipated settlement date.  

(3)Interest rate swap is included within other long-term liabilities.

(4)A deferred compensation plan assumed as part of a previous business combination is included within accrued liabilities and 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 footnote (1) above.

The estimated fair values of certain financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, approximate their respective carrying values due to their short maturity.

Contingent Consideration

We have classified our liabilities for contingent consideration related to acquisitions within Level 3 of the fair value hierarchy because the fair value is determined using significant unobservable inputs, which includes the achievements of future revenues. The contingent consideration is included within other short-term liabilities.

27

We record changes in the estimated fair value of contingent consideration in the unaudited condensed consolidated statements of income. Changes in contingent consideration liabilities are measured at fair value on a recurring basis using unobservable inputs (Level 3) and during the three and six months ended June 30, 2023, are as follows:

NOTE 19. HEDGING INSTRUMENTS

Disclosure within this note is presented to provide transparency about how and why we use derivative and non-derivative instruments (collectively “hedging 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.

We are exposed to certain risks related to our ongoing business operations. We utilize hedging instrument to manage a portion our foreign currency exchange risk and interest rate risk. During the first quarter of 2023, we entered into an interest rate swap to manage the impact of interest rate fluctuations associated with $250.0 million of borrowings under our variable-rate Credit Facility. We have designated the interest rate swap as a cash flow hedge.

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 other foreign currency exchange contracts, cross currency swaps, or foreign-denominated debt issuances to minimize the impact of foreign currency fluctuations associated with specific balance sheet exposures, including net investments in certain foreign subsidiaries.  

The primary purpose of our foreign currency hedging activities is to protect against the volatility associated with foreign currency transactions, including transactions denominated in the euro, British pound, Japanese yen, Canadian dollar, and Australian dollar. 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 foreign currency exchange contracts with well-capitalized 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.

We recognize all hedging instrument assets and liabilities at fair value at the balance sheet date. Instruments that do not qualify for hedge accounting treatment are recorded at fair value through earnings. To qualify for hedge accounting treatment, cash flow and net investment hedges must be highly effective in offsetting changes to expected future cash flows or fair value on hedged transactions. If the instrument qualifies for hedge accounting, changes in the fair value of the hedging instrument from the effective portion of the hedge are deferred in AOCI, net of tax, and 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 hedging instrument is not effective in achieving offsetting changes in fair value. We de-designate hedging instruments from hedge accounting when the likelihood of the hedged transaction occurring becomes less than probable. 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 AOCI at the time of de-designation is reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Refer to “Note 14. Accumulated Other Comprehensive Income” for further information regarding the effect of hedging instruments on our unaudited condensed consolidated statements of income for the three and six months ended June 30, 2023 and 2022.

We enter into master netting arrangements with the counterparties to our derivative transactions, which permit certain outstanding receivables and payables to be offset in the event of default. Our derivative contracts do not require either party to post cash collateral. We elect to present our derivative assets and liabilities in the unaudited condensed consolidated balance sheets on a gross basis. All cash flows related to our foreign currency exchange contracts are classified as operating cash flows, which is consistent with the cash flow treatment of the underlying items being hedged. 

28

Cash Flow Hedges 

We have designated our foreign currency exchange contracts and our interest rate swap as cash flow hedges as these derivative instruments manage our exposure to variability in the cash flows of forecasted transactions attributable to foreign currency exchange and interest rates on variable interest obligations under the terms of our Credit Facility. Unless noted otherwise, we have also designated our derivative instruments as qualifying for hedge accounting treatment.  

We did not de-designate any instruments from hedge accounting treatment during either the three and six months ended June 30, 2023 or 2022. As of June 30, 2023, the estimated amount of net gains, net of tax, from our foreign currency exchange contracts which are expected to be reclassified out of AOCI and into earnings within the next 12 months, is $0.6 million if exchange rates do not fluctuate from the levels as of June 30, 2023. 

Foreign Currency Exchange Contracts: We target to hedge approximately 75% to 85% of the estimated exposure from intercompany product purchases and sales denominated in the euro, British pound, Canadian dollar, Japanese yen, and Australian dollar. We have additional unhedged foreign currency exposures related to foreign services and emerging markets where it is not practical to hedge. We primarily utilize foreign currency exchange contracts with durations of less than 24 months. Quarterly, we enter into contracts to hedge incremental portions of anticipated foreign currency transactions for the current and following year. As a result, our risk with respect to foreign currency exchange rate fluctuations and the notional value of foreign currency exchange contracts may vary throughout the year. The U.S. dollar is the currency purchased or sold in all of our foreign currency exchange contracts. The notional amount of foreign currency exchange contracts to hedge forecasted intercompany inventory purchases and sales totaled $247.9 million and $258.2 million as of June 30, 2023 and December 31, 2022, respectively.

Interest Rate Swap: We entered into an interest rate swap contract to manage the economic effect of variable interest obligations on amounts borrowed under the terms of the Credit Facility. Beginning on March 31, 2023, the variable interest rate associated with $250.0 million of borrowings outstanding under the Credit Facility became effectively fixed at 3.9% plus the applicable credit spread, through October 20, 2025.

The following table presents the effect of cash flow hedge accounting on our unaudited condensed consolidated statements of income and comprehensive income, and provides information regarding the location and amounts of pretax gains or losses of derivatives:

Net Investment Hedges, Euro-Denominated Notes

In June 2015, we issued and sold through a private placement an aggregate principal amount of €88.9 million in euro-denominated 1.785% Series C Senior Notes due June 18, 2025. We have designated these euro-denominated notes as a hedge of our euro net investment in certain foreign subsidiaries to reduce the volatility in stockholders’ equity caused by changes in foreign currency exchange rates in the euro relative to the U.S. dollar. As a result of this designation, gains and losses from the change in translated U.S. dollar value of these euro-denominated notes are recorded in AOCI rather than to earnings. We recorded losses of $0.4 million and $1.8 million, net of tax, within AOCI as a result of this net investment hedge for the three and six months ended June 30, 2023, respectively, and gains of $4.1 million and $5.5 million for the three and six months ended June 30, 2022, respectively. The related cumulative unrealized gain recorded as of June 30, 2023, will be reclassified to earnings when the foreign subsidiaries are sold or substantially liquidated or all or a portion of the hedge no longer qualifies for hedge accounting treatment. Refer to Note 13 to the consolidated financial statements included in our 2022 Annual Report for further information regarding the issuance of these euro-denominated notes.

Net Investment Hedges, Cross Currency Swaps

We have entered into several cross currency swap contracts as a hedge of our net investment in foreign operations to offset foreign currency translation gains and losses on the net investment. These cross currency swaps have maturity dates beginning on June 30, 2025, through June 30, 2028. At maturity of the cross currency swap contracts we will deliver the notional amount of €15 million and will receive approximately $17.5 million from the counterparties on June 18, 2025; we will deliver the notional amount of €35 million and will receive $37.8 million from the counterparties on March 31, 2028; and we will deliver the notional amount of €90 million and will receive $98.2 million from the counterparties on June 30, 2028. The changes in fair value of the cross currency swap contracts are recorded in AOCI and will be reclassified to earnings when the foreign subsidiaries are sold or substantially liquidated. During the three and six months ended June 30, 2023, we recorded losses of $1.8 million and $3.0 million, net of tax, respectively, within AOCI as a result of these net investment hedges, and gains of $4.3 million and gains of $5.3 million during the three and six months ended June 30, 2022, respectively. We will receive quarterly interest payments from the counterparties based on a fixed interest rate until maturity of the cross currency swaps. This interest rate component is excluded from the assessment of hedge effectiveness and is recognized as a reduction to interest expense over the life of the hedge instrument. We recognized approximately $0.8 million and $1.5 million related to the excluded component as a reduction of interest expense for the three and six months ended June 30, 2023, respectively, and $0.7 million and $1.4 million and for the three and six months ended June 30, 2022, respectively.

During the second quarter of 2023, the notional amount of €90.0 million in cross currency swaps matured, resulting in a net cash receipt of $6.3 million. The receipt of cash is reflected within financing activities on the Condensed Consolidated Statements of Cash Flows.

Item 1. Financial Statements” of this Quarterly Report on Form 10-Q.

Our fiscal quarter ended on June 30. Unless otherwise stated, the analysis and discussion of our financial condition and results of operations below, including references to growth and organic growth and increases and decreases, are being compared to the equivalent prior-year periods.

Business Overview 

We develop, manufacture, and distribute products and provide services primarily for the companion animal veterinary, livestock, poultry and dairy, and water testing sectors. We also design, manufacture, and distribute point of care and laboratory diagnostics for the human medical diagnostics sector. Our primary products and services are:

•Point-of-care veterinary diagnostic products, comprising instruments, consumables, and rapid assay test kits;

•Veterinary reference laboratory diagnostic and consulting services;

•Practice management and diagnostic imaging systems and services used by veterinarians;

•Health monitoring, biological materials testing, and laboratory diagnostic instruments and services used by the biomedical research community;

•Diagnostic, health-monitoring products for livestock, poultry, and dairy;

•Products that test water for certain microbiological contaminants; and

•Point-of-care electrolytes and blood gas analyzers.

Description of Business Segments. We operate primarily through three business segments: diagnostic and information management-based products and services for the companion animal veterinary industry, which we refer to as the Companion Animal Group (“CAG”), water quality products (“Water”), and diagnostic products and services for livestock and poultry

32

health and to ensure the quality and safety of milk and improve producer efficiency, which we refer to as Livestock, Poultry and Dairy (“LPD”). Our Other operating segment combines and presents our human medical diagnostics products and services business (“OPTI Medical”) with our out-licensing arrangements because they do not meet the quantitative or qualitative thresholds for reportable segments. 

CAG develops, designs, manufactures, and distributes products and software, and performs services for veterinarians and the biomedical analytics sector, 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 software and performs services that are used to manage the health status of livestock and poultry, to improve bovine reproductive efficiency, and to ensure the quality and safety of milk. OPTI Medical develops, designs, manufactures, and distributes point-of-care and laboratory diagnostics (including electrolyte and blood gas analyzers and related consumable products) for the human medical diagnostics sector. During the first quarter of 2023, we discontinued actively marketing our OPTI COVID-19 PCR testing products and services.

Currency and Other Items

Currency Impact. Refer to “Part I, Item 3. Quantitative and Qualitative Disclosures about Market Risk” included in this Quarterly Report on Form 10-Q for additional information regarding the impact of foreign currency exchange rates.

Other Items. Refer to “Part I, Item 1. Business - Patents and Licenses” and “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our 2022 Annual Report for additional information regarding trends in companion animal healthcare, distributor purchasing and inventories, economic conditions, and patent expiration.

Critical Accounting Estimates and Assumptions 

The discussion and analysis of our financial condition and results of operations is based upon our unaudited 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. We evaluate our estimates on an ongoing basis. 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 critical accounting policies and the significant judgments and estimates used in the preparation of our unaudited condensed consolidated financial statements for the three and six months ended June 30, 2023, are consistent with those discussed in our 2022 Annual Report in the section under the heading “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Estimates and Assumptions.”  

Recent Accounting Pronouncements 

For more information regarding the impact that recent accounting standards and amendments will have on our consolidated financial statements, refer to Note 2 to the unaudited condensed consolidated financial statements in “Part I. Item 1. Financial Statements” of this Quarterly Report on Form 10-Q.

Non-GAAP Financial Measures

The following revenue analysis and discussion focuses on organic revenue growth, and references in this analysis and discussion to “revenue,” “revenues,” or “revenue growth” are references to “organic revenue growth.” Organic revenue growth is a non-GAAP financial measure and represents the percentage change in revenue during the three and six months ended June 30, 2023, as compared to the same periods for the prior year, net of the effect of changes in foreign currency exchange rates, certain business acquisitions, and divestitures. Organic revenue growth should be considered in addition to, and not as a replacement for, or as a superior measure to, revenue growth 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 the performance of our peers.

We exclude from organic revenue growth 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 calculate the impact on revenue resulting from changes in foreign currency exchange rates by applying the

33

difference between the weighted average exchange rates during the current year period and the comparable prior-year period to foreign currency denominated revenues for the prior-year period. 

We also exclude from organic revenue growth the effect of certain business acquisitions and divestitures because the nature, size, and number of these transactions can vary dramatically from period to period, and because they either require or generate cash as an inherent consequence of the transaction, and therefore can also obscure underlying business and operating trends. We consider acquisitions to be a business when all three elements of inputs, process, and outputs are present, consistent with ASU 2017-01, “Business Combinations: (Topic 805) Clarifying the Definition of a Business.” In a business combination, if substantially all the fair value of the assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, we do not consider these assets to be a business. A typical acquisition that we do not consider a business is a customer list asset acquisition, which does not have all elements necessary to operate a business, such as employees or infrastructure. We believe the efforts required to convert and retain these acquired customers are similar in nature to our existing customer base and therefore are included in organic revenue growth. The percentage change in revenue resulting from acquisitions represents revenues during the current year period, limited to the initial 12 months from the date of the acquisition, that are directly attributable to business acquisitions.

We also use Adjusted EBITDA, gross debt, net debt, gross debt to Adjusted EBITDA ratio and net debt to Adjusted EBITDA ratio, in this Quarterly Report on Form 10-Q, all of which are non-GAAP financial measures that should be considered in addition to, and not as a replacement for, financial measures presented according to U.S. GAAP. Management believes that reporting these non-GAAP financial measures provides supplemental analysis to help investors further evaluate our business performance and available borrowing capacity under our Credit Facility.

(1)Reported revenue growth and organic revenue growth may not recalculate due to rounding.

Total Company Revenue. The increase in organic revenue reflects growth in CAG Diagnostics recurring revenue, including benefits from higher realized prices globally and increased volume in the U.S. and International regions. Increases in our subscription-based veterinary software and diagnostic imaging services also contributed to higher revenue. Higher revenue in our Water business was primarily due to higher realized prices and higher testing volumes in certain international regions, as well as the benefit of an acquisition in the third quarter of 2022. LPD revenue was relatively flat compared to the same period in the prior year as price gains and higher volumes in our poultry and swine testing were partially offset by lower herd health screening volumes. The decrease in Other revenue reflects lower sales of OPTI COVID-19 PCR testing products and services, and lower volumes of our OPTI Medical instruments and consumables internationally. The impact of foreign currency movements decreased total revenue growth by 0.5%.

Gross Profit. Gross profit increased due to higher revenue and a 100 basis point increase in the gross profit margin. The increase in the gross profit margin was primarily due to recurring revenue net price gains, the benefit of reference laboratory and operational productivity initiatives, improved software services gross margins, and product mix associated with lower CAG Diagnostics instrument revenue. These increases were partially offset by higher product and labor costs, which reflect the effects of inflation, as well as investments in productivity initiatives and to support future growth. The impact from foreign currency movements decreased the gross profit margin by approximately 60 basis points, including the impact of lower hedge gains in the current year, as compared to the prior year.

Operating Expenses. Sales and marketing expense increased primarily due to higher personnel-related and travel costs, including investments in our global commercial capability. General and administrative expense increased primarily due to higher personnel-related costs. Research and development expense decreased primarily due to the comparison to the prior year acquisition of rights to use certain licensed technology for $80 million, partially offset by higher personnel-related and project costs. The overall change in foreign currency exchange rates was immaterial on operating expenses growth.

Revenue. Revenue was relatively flat compared to the same period in the prior year. Price gains and higher poultry and swine testing volumes in the U.S. were partially offset by lower herd health screening revenues primarily related to reduced China import levels. The unfavorable impact of foreign currency movements decreased revenue growth by 0.5%.

Gross Profit. The decrease in gross profit was primarily due to a 310 basis point decrease in the gross profit margin. The impact from foreign currency movements, including the impact of hedge losses in the current year compared to hedge gains in the prior year, decreased the gross profit margin by approximately 510 basis points. Excluding the impact of foreign currency movements, the increase in the gross profit margin was primarily due to higher realized prices, partially offset by unfavorable sales mix impacts related to lower herd health screening volumes.

Operating Expenses. Sales and marketing expense increased primarily due to increases in personnel-related costs. General and administrative expense increased primarily due to increases in personnel-related costs. Research and development costs were relatively constant compared to the prior year.

Revenue. The decrease in revenue was primarily due to lower sales of OPTI COVID-19 PCR testing products and services in the U.S., following our discontinuation of active marketing of such products and services in the first quarter of 2023, as well as lower volumes of our OPTI Medical instruments and consumables internationally, partially offset by higher realized prices.

Gross Profit. Gross profit decreased due to lower sales volume and a 2,820 basis point decrease in the gross profit margin. The decrease in the gross profit margin was primarily due to sales mix with lower OPTI COVID-19 PCR testing volumes, and higher product and distribution costs, partially offset by higher realized prices. The overall change in foreign currency exchange rates had an immaterial impact on gross profit.

Operating Expenses. General and administrative expense decreased primarily due to lower foreign exchange losses on settlements of foreign currency denominated transactions, as compared to the prior year, partially offset by higher bad debt expense. Foreign exchange losses on settlements for all operating segments are reported within our Other segment. Research and development expense decreased primarily due to lower product development costs compared to investments in the development of infectious disease tests during the prior year.

Non-Operating Items

Interest Expense. Interest expense was $10.5 million for the three months ended June 30, 2023, as compared to $8.3 million for the same period in the prior year. The increase in interest expense was primarily the result of higher interest rates, partially offset by lower average debt levels.

Provision for Income Taxes. Our effective income tax rate was 21.6% for the three months ended June 30, 2023, as compared to 22.9% for the three months ended June 30, 2022. The decrease in our effective tax rate was primarily driven by geographical income mix, partially offset by a decrease in the tax rate benefits related to share-based compensation.

(1)Reported revenue growth and organic revenue growth may not recalculate due to rounding.

Total Company Revenue. The increase in organic revenue reflects growth in CAG Diagnostics recurring revenue, including benefits from higher realized prices globally and increased volume in the U.S. Increases in our subscription-based veterinary software and diagnostic imaging services also contributed to higher revenue. Higher revenue in our Water business was primarily due to higher realized prices and higher testing volumes in certain international regions, as well as the benefit of our acquisition in the third quarter of 2022. The decline in our LPD business was primarily due to lower herd health screening volume, partially offset by higher realized prices. The decrease in Other revenue reflects lower sales of OPTI COVID-19 PCR testing products and services, and lower volumes of our OPTI Medical instruments and consumables internationally. The impact of currency movements decreased total revenue growth by 1.4%.

Revenue. The increase in revenue was due to higher realized prices and, to a lesser extent, higher testing primarily in Europe. The impact of currency movements decreased revenue growth by 2.0%. The impact of the acquisition completed during the third quarter of 2022 increased revenue growth by 1.7%.

Gross Profit. Gross profit increased due to higher revenue. The impact from foreign currency movements, including the impact of lower hedge gains in the current year compared to the prior year, decreased the gross profit margin by approximately 140 basis points. Excluding the impact of foreign currency movements, the increase in the gross profit margin was primarily due to higher realized prices.

Operating Expenses. Sales and marketing expense increased primarily due to higher personnel-related costs. General and administrative expense increased primarily due to higher personnel-related costs and incremental costs associated with the acquisition that occurred in the third quarter of 2022. Research and development expense increased primarily due to higher project and personnel-related costs, partially offset by lower third-party costs. The overall change in foreign currency exchange rates resulted in a decrease in operating expenses growth by approximately 1%.

Income from operations	$	3,259	5.5	%	$	9,967	16.4	%	$	(6,708)	(67.3	%)

Revenue. Revenue decreased primarily due to lower herd health screening revenues related to reduced China imports, partially offset by price gains and higher volumes in our swine, poultry, and ruminant testing in certain regions. The unfavorable impact of foreign currency movements decreased revenue growth by 2.2%.

Gross Profit. The decrease in gross profit was primarily due to lower sales volumes and a 740 basis point decrease in the gross profit margin. The decrease in the gross profit margin is primarily due to higher product costs and, to a lesser extent, sales mix, partially offset by higher realized prices. The impact from foreign currency movements decreased the gross profit margin by approximately 390 basis points, including the impact of hedge losses in the current year compared to hedge gains in the prior year.

Operating Expenses. Sales and marketing expense increased primarily due to increases in personnel-related and travel costs. General and administrative costs and research and development costs were relatively constant compared to the prior year. The overall change in foreign currency exchange rates resulted in a decrease in operating expenses growth by approximately 1%.

Income from operations	$	(766)	(8.6	%)	$	3,218	20.8	%	$	(3,984)	(123.8	%)

Revenue. The decrease in revenue was primarily due to lower sales of OPTI COVID-19 PCR testing products and services in the U.S., following our discontinuation of active marketing of such products and services in the first quarter of 2023, and lower volumes of our OPTI Medical instruments and consumables internationally, partially offset by higher realized prices.

Gross Profit. Gross profit decreased due to lower sales volume and a 2,060 basis point decrease in the gross profit margin. The decrease in the gross profit margin was primarily due to sales mix with lower OPTI COVID-19 PCR testing volumes, and higher product, freight, and distribution costs, partially offset by higher realized prices. The overall change in foreign currency exchange rates had an immaterial impact on gross profit.

Operating Expenses. General and administrative expense decreased primarily due to lower foreign exchange losses on settlements of foreign currency denominated transactions, as compared to the prior year, partially offset by higher bad debt expense. Foreign exchange losses on settlements for all operating segments are reported within our Other segment. Research and development expense decreased primarily due to lower product development costs compared to investments in the development of infectious disease tests during the prior year.

Non-Operating Items

Interest Expense. Interest expense was $23.7 million for the six months ended June 30, 2023, as compared to $15.3 million for the same period in the prior year. The increase in interest expense was primarily the result of higher interest rates, partially offset by lower average debt levels.

Provision for Income Taxes. Our effective income tax rate was 20.8% for the six months ended June 30, 2023, compared to 21.0% for the six months ended June 30, 2022. The decrease in our effective tax rate was primarily driven by geographical income mix, partially offset by a decrease in the tax rate benefits related to share-based compensation.

Liquidity and Capital Resources  

We fund the capital needs of our business through cash on hand, funds generated from operations, proceeds from long-term senior note financings, and amounts available under our Credit Facility. We generate cash primarily through the payments made by customers for our companion animal veterinary, livestock, poultry, dairy, and water products and services, consulting services, and other various systems and services. Our cash disbursements are primarily related to compensation and benefits for our employees, inventory and supplies, taxes, research and development, capital expenditures, rents, occupancy-related charges, interest expense, and business acquisitions. As of June 30, 2023, we had $132.8 million of cash and cash equivalents, as compared to $112.5 million as of December 31, 2022. Working capital totaled $295.2 million as of June 30, 2023, as compared to negative $134.3 million as of December 31, 2022. The change in working capital is primarily due to lower outstanding borrowings under our Credit Facility. As of June 30, 2023, we had borrowing availability of $984.5 million under our $1.25 billion Credit Facility, with $264.0 million in outstanding borrowings under the Credit Facility. The general availability of funds under our Credit Facility is reduced by $1.5 million for outstanding letters of credit. We believe that, if necessary, we could obtain additional borrowings to fund our growth objectives. We further believe that current cash and cash equivalents, funds generated from operations, and committed borrowing availability will be sufficient to fund our operations, capital purchase requirements, and anticipated growth needs for the next twelve months. We believe that these resources, coupled with our ability, as needed, to obtain additional financing, will also be sufficient to fund our business as currently conducted for the foreseeable future. We may enter into new financing arrangements or refinance or retire existing debt in the future depending on market conditions. Should we require more capital than is generated by our operations, for example, to fund significant discretionary activities, we could elect to raise capital through the incurrence of debt or equity issuances, which we may not be able to complete on favorable terms or at all. In addition, these alternatives could result in increased interest expense or other dilution of our earnings.

We manage our worldwide cash requirements considering available funds among all of our subsidiaries. Our foreign cash, cash equivalents, and marketable securities are generally available without restrictions to fund ordinary business operations outside the U.S. 

The following table presents cash, cash equivalents, and marketable securities held domestically and by our foreign subsidiaries:

Cash, cash equivalents and marketable securities (dollars in thousands)	June 30, 2023		December 31, 2022
U.S.	$	7,559	$	16,112
Foreign	125,279		96,434
Total	$	132,838	$	112,546
Total cash, cash equivalents, and marketable securities held in U.S. dollars by our foreign subsidiaries	$	7,153	$	6,647

Of the $132.8 million of cash and cash equivalents held as of June 30, 2023, greater than 99% was held as bank deposits at a diversified group of institutions, primarily systemically important banks. Cash and cash equivalents as of June 30, 2023, included approximately $2.4 million in cash denominated in non-U.S. currencies held in countries with currency control restrictions, which limit our ability to transfer funds outside of the countries in which they are held. The currency control restricted cash is generally available for use within the country where it is held.

The following table presents additional key information concerning working capital: 

	For the Three Months Ended
	June 30, 2023	March 31, 2023	December 31, 2022	September 30, 2022	June 30, 2022
Days sales outstanding (1)	43.9	42.9	43.4	43.4	43.2
Inventory turns (2)	1.3	1.3	1.3	1.3	1.5

(1)     Days sales outstanding represents the average of the accounts receivable balances at the beginning and end of each quarter divided by revenue for that quarter, the result of which is then multiplied by 91.25 days.

(2)     Inventory turns represent inventory-related cost of product revenue for the 12 months preceding each quarter-end divided by the average inventory balances at the beginning and end of each quarter.

Sources and Uses of Cash 

The following table presents cash provided (used):

	For the Six Months Ended June 30,
(dollars in thousands)	2023		2022		Change
Net cash provided by operating activities	$	384,226	$	180,556	$	203,670
Net cash used by investing activities	(66,981)		(96,924)		29,943
Net cash used by financing activities	(297,114)		(105,387)		(191,727)
Net effect of changes in exchange rates on cash	161		(8,337)		8,498
Net change in cash and cash equivalents	$	20,292	$	(30,092)	$	50,384

Operating Activities. The increase in cash provided by operating activities of $203.7 million was driven primarily by an increase in net income, including the comparative increase in comparison to net income as a result of higher research and development investments in the prior year, and changes in other assets and liabilities. The following table presents cash flow impacts from changes in operating assets and liabilities: 

	For the Six Months Ended June 30,
(dollars in thousands)	2023		2022		Change
Accounts receivable	$	(61,158)	$	(53,794)	$	(7,364)
Inventories	(38,906)		(49,349)		10,443
Accounts payable	(4,155)		(6,735)		2,580
Deferred revenue	(1,855)		(2,344)		489
Other assets and liabilities	(24,236)		(94,729)		70,493
Total change in cash due to changes in operating assets and liabilities	$	(130,310)	$	(206,951)	$	76,641

Cash used decreased due to changes in operating assets and liabilities during the six months ended June 30, 2023, as compared to the same period in the prior year, by approximately $76.6 million. The increase in cash used by accounts receivable was primarily due to higher revenue growth during the current period. The decrease in cash used by inventories was primarily due to increases in the prior year to mitigate supply chain risks. The decrease of cash used for other assets and liabilities was primarily due to higher non-cash operating expenses recorded as accrued liabilities for personnel-related costs and lower annual employee incentive program payments in the current year, and lower tax payments in the current year, as compared to the same period in the prior year, partially offset by milestone payments to license intellectual property made in the current year.

We have historically experienced proportionally lower net cash flows from operating activities during the first quarter and proportionally higher cash flows from operating activities for the remainder of the year driven primarily by payments related to annual employee incentive programs in the first quarter following the year for which the bonuses were earned.

Investing Activities. Cash used by investing activities was $67.0 million for the six months ended June 30, 2023, as compared to $96.9 million for the same period in the prior year. The decrease in cash used by investing activities was primarily due to the comparison to the prior year equity investment and acquisition of intangible assets, partially offset by higher investments in property and equipment in the current year primarily related to the construction of our facility in Scarborough, Maine.

Our total capital expenditure plan for 2023 is estimated to be approximately $180.0 million, which includes capital investments to support growth in manufacturing and operations facilities and in customer-facing software.

Financing Activities. Cash used by financing activities was $297.1 million for the six months ended June 30, 2023, as compared to $105.4 million of cash used for the same period in the prior year. The increase in cash used by financing activities was due to $315.0 million cash used for repayments under our Credit Facility in the current year, compared to borrowings of $537.5 million under our Credit Facility, partly offset by cash used to pay off our $75.0 million 2022 Series A Notes in the prior year. The increase in cash used by financing activities was also partly offset by $573.1 million cash used to repurchase our common stock in the prior year.

50

During the six months ended June 30, 2023, we did not purchase any shares of our common stock in the open market. During the six months ended June 30, 2022, we purchased $573.1 million of shares of our common stock. We believe that the repurchase of our common stock is a favorable means of returning value to our stockholders, and we also repurchase our stock to offset the dilutive effect of our share-based compensation programs. Repurchases of our common stock may vary depending upon the level of other investing and deployment activities, as well as share price and prevailing interest rates. Refer to Note 12 to the unaudited condensed consolidated financial statements in “Part I. Item 1. Financial Statements” of this Quarterly Report on Form 10-Q for additional information about our share repurchases.

Under our Credit Facility, the net borrowing activity during the six months ended June 30, 2023, as compared to the same period in the prior year, decreased $315.0 million. As of June 30, 2023, we had $264.0 million in outstanding borrowings under the Credit Facility. The obligations under our Credit Facility may be accelerated upon the occurrence of an event of default under the Credit Facility, which includes customary events of default including payment defaults, defaults in the performance of the affirmative, negative and financial 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 (“ERISA”), the failure to pay specified indebtedness, cross-acceleration to 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.

In February 2022, we paid off our $75.0 million 2022 Series A Notes with cash provided by operations and financing activity. The aggregate principal amounts of our 2023 Series A Notes for $75.0 million will become due and payable on December 11, 2023. We anticipate paying off our 2023 Series A Notes for $75.0 million when due in December 2023 with cash provided by operations. Should we elect to prepay any of our senior notes, such aggregate prepayment will include the applicable make-whole amount(s), as defined within the applicable Senior Note Agreements. Additionally, in the event of a change in control of the Company or upon the disposition of certain assets of the Company, the proceeds of which are not reinvested (as defined in the Senior Note Agreements), we may be required to prepay all or a portion of the senior notes. The obligations under the senior notes may be accelerated upon the occurrence of an event of default under the applicable Senior Note Agreements, each of which includes customary events of default including payment defaults, defaults in the performance of the affirmative, negative and financial 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 ERISA, the failure to pay specified indebtedness, cross-acceleration to specified indebtedness, and a change of control default.

Effect of Currency Translation on Cash. The net effect of changes in foreign currency exchange rates is related to changes in exchange rates between the U.S. dollar and the functional currencies of our foreign subsidiaries. These changes will fluctuate for each period presented as the value of the U.S. dollar relative to the value of foreign currencies changes. A currency’s value depends on many factors, including interest rates and the issuing governments’ debt levels and strength of economy.

Off-Balance Sheet Arrangements. We have no off-balance sheet arrangements or variable interest entities, except for letters of credit and third-party guarantees.

51

Financial Covenant. The sole financial covenant of our Credit Facility and Senior Note Agreements is a consolidated leverage ratio test that requires our ratio of debt to earnings before interest, taxes, depreciation and amortization, non-recurring transaction expenses incurred in connection with acquisitions, share-based compensation expense, and certain other non-cash losses and charges (“Adjusted EBITDA”), as defined in the Senior Note Agreement and Credit Facility, not to exceed 3.5-to-1. As of June 30, 2023, we were in compliance with such covenant. The following details our consolidated leverage ratio calculation:

(dollars in thousands)	Twelve Months Ended
Trailing 12 Months Adjusted EBITDA:	June 30, 2023
Net income attributable to stockholders (as reported)	$	791,435
Interest expense	48,214
Provision for income taxes	209,580
Depreciation and amortization	113,453
Acquisition-related expense	322
Share-based compensation expense	55,519
Extraordinary and other non-recurring non-cash charges	—
Adjusted EBITDA	$	1,218,523
Debt to Adjusted EBITDA Ratio:	June 30, 2023
Credit facility	$	264,000
Current and long-term portions of long-term debt	771,835
Total debt	1,035,835
Acquisition-related contingent consideration payable	1,663
Financing leases	—
Deferred financing costs	357
Gross debt	$	1,037,855
Gross debt to Adjusted EBITDA ratio	0.85
Less: Cash and cash equivalents	$	132,838
Net debt	$	905,017
Net debt to Adjusted EBITDA ratio	0.74

Adjusted EBITDA, gross debt, net debt, gross debt to Adjusted EBITDA ratio, and net debt to Adjusted EBITDA ratio are non-GAAP financial measures which should be considered in addition to, and not as a replacement for, financial measures presented according to U.S. GAAP. Management believes that reporting these non-GAAP financial measures provides supplemental analysis to help investors further evaluate our business performance and available borrowing capacity under our Credit Facility. 

Other Commitments, Contingencies and Guarantees 

Significant commitments, contingencies, and guarantees as of June 30, 2023, are described in Note 16 to the unaudited condensed consolidated financial statements in “Part I. Item 1. Financial Statements” of this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk 

For quantitative and qualitative disclosures about market risk affecting us, refer to the section under the heading “Part II. Item 7A. Quantitative and Qualitative Disclosure About Market Risk” of our 2022 Annual Report. As of the date of this Quarterly Report on Form 10-Q, there have been no material changes to the market risks described in our 2022 Annual Report, except for the impact of foreign exchange rates, as discussed below. 

Foreign Currency Exchange Impacts. Approximately 21% of our consolidated revenue was derived from products manufactured in the U.S. and sold internationally in local currencies for both the three and six months ended June 30, 2023, as compared to approximately 21% and 22% for the three and six months ended June 30, 2022, respectively. Strengthening of the U.S. dollar exchange rate 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 impact of foreign currency denominated costs and expenses and foreign currency denominated supply contracts partly offsets this exposure. Additionally, our designated hedges of intercompany inventory purchases and sales help delay the impact of certain exchange rate fluctuations on non-U.S. dollar denominated revenues.

Our foreign currency exchange impacts are comprised of three components: 1) local currency revenues and expenses; 2) the impact of hedge contracts; and 3) intercompany and monetary balances for our subsidiaries that are denominated in a currency that is different from the functional currency used by each subsidiary.

The following table presents the estimated foreign currency exchange impact on our revenues, operating profit, and diluted earnings per share for the current period and as compared to the respective prior-year period:

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
(in thousands, except per share amounts)	2023		2022		2023		2022
Revenue impact	$	(4,175)	$	(27,597)	$	(22,525)	$	(42,661)
Operating profit impact, excluding hedge activity and exchange impacts on settlement of foreign currency denominated transactions	$	(2,627)	$	(14,769)	$	(13,063)	$	(22,708)
Hedge gains - current period	115		5,781		450		8,017
Exchange (losses) on settlements of foreign currency denominated transactions - current period	(593)		(832)		(675)		(1,607)
Operating profit impact - current period	$	(3,105)	$	(9,820)	$	(13,288)	$	(16,298)
Hedge (gains) losses - prior period	(5,781)		2,715		(8,017)		5,145
Exchange losses on settlement of foreign currency denominated transactions - prior period	832		854		1,607		924
Operating profit impact - as compared to prior period	$	(8,054)	$	(6,251)	$	(19,698)	$	(10,229)
Diluted earnings per share impact - as compared to prior period	$	(0.07)	$	(0.06)	$	(0.18)	$	(0.10)

53

At our current foreign currency exchange rate assumptions, we anticipate the effect of a weaker U.S. dollar for the remainder of the year, as compared to the respective prior-year period, will have a net unfavorable impact on our operating results for the remainder of the year ending December 31, 2023, by increasing our revenues by approximately $30 million, and decreasing our operating profit and diluted earnings per share by approximately $3 million and $0.02 per share, respectively. This unfavorable year-over-year currency impact includes foreign currency hedging activity, which is expected to decrease our total operating profit by approximately $17 million and $0.16 per share for the remainder of the year ended December 31, 2023. The actual impact of changes in the value of the U.S. dollar against foreign currencies in which we transact may materially differ from our expectations described above. The above estimates assume that the value of the U.S. dollar will reflect the euro at $1.10, the British pound at $1.27, the Canadian dollar at $0.75, and the Australian dollar at $0.67; and the Japanese yen at ¥142, the Chinese renminbi at RMB 7.27, and the Brazilian real at R$4.86 relative to the U.S. dollar for the remainder of 2023.

Based on projected revenues and expenses for the remainder of 2023, excluding the impact of intercompany and trade balances denominated in currencies other than the functional subsidiary currencies, we project a 1% strengthening of the U.S. dollar would reduce revenue by approximately $6.0 million and operating income by approximately $1.6 million, net of hedge positions.

Interest Rate Impacts. We entered into an interest rate swap to manage the effect of variable interest obligations on amounts borrowed under the terms of the Credit Facility. Beginning on March 31, 2023, the variable interest rate associated with $250.0 million of borrowings outstanding under the Credit Facility became effectively fixed at 3.9% plus the applicable credit spread, through October 20, 2025. Borrowings outstanding under the Credit Facility at June 30, 2023, were $264.0 million. We have designated the interest rate swap as a cash flow hedge. For more information regarding our interest rate swap, refer to “Part I, Item 1. Financial Statements, Note 19. Hedge Instruments.”

Item 4. Controls and Procedures 

Disclosure Controls and Procedures 

Our management is responsible for establishing and maintaining disclosure controls and procedures, as defined by the SEC in its Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 as amended (the “Exchange Act”). The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act are recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a 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, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of June 30, 2023, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.  

Changes in Internal Control Over Financial Reporting 

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended June 30, 2023, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 

54

PART II — OTHER INFORMATION 

Item 1. Legal Proceedings

Due to the nature of our activities, we are at times subject to pending and threatened legal actions that arise out of the ordinary course of business. In the opinion of management, based in part upon advice of legal counsel, the disposition of any such currently pending matters is not expected to have a material effect on our results of operations, financial condition, or cash flows. However, the results of legal actions cannot be predicted with certainty. Therefore, it is possible that our results of operations, financial condition, or cash flows could be materially adversely affected in any particular period by the unfavorable resolution of one or more legal actions.

Item 1A. Risk Factors 

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors discussed in “Part I. Item 1A. Risk Factors” in our 2022 Annual Report, which could materially affect our business, financial condition, or future results. There have been no material changes from the risk factors previously disclosed in the 2022 Annual Report. The risks described in our 2022 Annual Report are not the only risks facing our Company. 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, or future results.

55

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds 

During the three months ended June 30, 2023, we repurchased shares of common stock as described below:  

Period	Total Number of Shares Purchased (a)		Average Price Paid per Share (b)		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs (1) (c)	Maximum Number of Shares that May Yet Be Purchased Under the Plans or Programs (1) (d)
April 1 to April 30, 2023	—		$	—	—	3,029,242
May 1 to May 31, 2023	—		$	—	—	3,029,242
June 1 to June 30, 2023	168		$	469.84	—	3,029,242

(1)On August 13, 1999, our Board of Directors approved and announced the repurchase of our common stock in the open market or in negotiated transactions pursuant to the Company’s share repurchase program. The authorization has been increased by the Board of Directors on numerous occasions; most recently, on February 12, 2020, the maximum level of shares that may be repurchased under the program was increased from 68 million to 73 million shares. There is no specified expiration date for this share repurchase program. There were no other repurchase programs outstanding during the three months ended June 30, 2023, and no share repurchase programs expired during the period. There were no share repurchases made during the three months ended June 30, 2023, in transactions made pursuant to our share repurchase program.

(2)During the three months ended June 30, 2023, we received 168 shares of our common stock that were surrendered by employees in payment for the minimum required withholding taxes due on the vesting of restricted stock units. In the above table, these shares are included in columns (a) and (b), but excluded from columns (c) and (d). These shares do not reduce the number of shares that may yet be purchased under the share repurchase program.

The total shares repurchased include shares surrendered for employee statutory tax withholding. Refer to Note 12 to the unaudited condensed consolidated financial statements in “Part I. Item 1. Financial Statements” of this Quarterly Report on Form 10-Q for additional information about our share repurchases.

Basis of Presentation and Principles of Consolidation

BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION 

The accompanying unaudited condensed consolidated financial statements of IDEXX Laboratories, Inc. and its subsidiaries have been prepared in accordance with 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 this Quarterly Report on Form 10-Q. Unless the context requires otherwise, references in this Quarterly Report on Form 10-Q to “IDEXX,” the “Company,” “we,” “our,” or “us” refer to IDEXX Laboratories, Inc. and its subsidiaries.

The accompanying unaudited condensed consolidated financial statements include the accounts of IDEXX Laboratories, Inc. and our wholly-owned and majority-owned subsidiaries. We do not have any variable interest entities for which we are the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation.

The accompanying unaudited condensed consolidated financial statements reflect, in the opinion of our management, all adjustments necessary for a fair statement of our financial position and results of operations. All such adjustments are of a recurring nature. The condensed consolidated balance sheet data as of December 31, 2022, 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 six months ended June 30, 2023, are not necessarily indicative of the results to be expected for the full year or any future period. These unaudited condensed consolidated financial statements should be read in conjunction with this Quarterly Report on Form 10-Q for the quarter ended June 30, 2023, and our Annual Report on Form 10-K for the year ended December 31, 2022, (the “2022 Annual Report”) filed with the SEC.

The preparation of our condensed consolidated financial statements requires us to make estimates, judgments, and assumptions that may affect the reported amounts of assets, liabilities, equity, revenues, and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis we evaluate our estimates, judgments, and methodologies. We base our estimates on historical experience and on various other assumptions that we believe are reasonable, the results of which form the basis for making judgments about the carrying values of assets, liabilities, and equity, and the amount of revenues and expenses.

We have included certain terms and abbreviations used throughout this Quarterly Report on Form 10-Q in the “Glossary of Terms and Selected Abbreviations.”

ACCOUNTING POLICIES  

Significant Accounting Policies

The significant accounting policies used in preparation of these unaudited condensed consolidated financial statements as of and for the three and six months ended June 30, 2023, are consistent with those discussed in “Note 2. Summary of Significant Accounting Policies” to the consolidated financial statements in our 2022 Annual Report, and as updated below.

Accounts Payable - Supplier Financing Program

We have an agreement with a third party to provide a supplier finance program, which facilitates participating suppliers’ ability to finance payment obligations from us with a designated third-party financial institution. Participating suppliers may, at their sole discretion, make offers to finance one or more of our payment obligations prior to their scheduled due dates at a discounted price. Our obligations to our suppliers, including amounts due and scheduled payment dates, are not impacted by suppliers’ decisions to finance amounts under these arrangements. The terms of payments are in-line with the terms of our trade payables. Activity related to the obligations is presented within operating activities on the unaudited consolidated statements of cash flows. The changes in our outstanding payment obligations under this arrangement, which are included in accounts payable on the unaudited condensed consolidated balance sheets, are as follows:

(in thousands)	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2023		2022		2023		2022

Payment obligations outstanding at the end of the period	$	5,395	$	8,010	$	5,395	$	8,010

New Accounting Pronouncements Adopted

We adopted ASU 2022-04, “Liabilities - Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations,” as of January 1, 2023, which adds certain disclosure requirements for a buyer in a supplier finance program. The amendments in this update require that a buyer in a supplier finance program discloses sufficient information about the program to allow a user of financial statements to understand the program's nature, activity during the period, changes from period to period, and potential magnitude.

We adopted ASU 2021-08, “Business Combinations (Topic 805): Accounting for Acquired Contract Assets and Contract Liabilities,” as of January 1, 2023. ASU 2021-08 is intended to improve comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of and after a business combination by providing consistent recognition guidance. The adoption of ASU 2021-08 did not have a material impact on our unaudited condensed consolidated financial statements.

Revenue Recognition

6 Months Ended

Jun. 30, 2023

Revenue from Contract with Customer [Abstract]

Revenue Recognition

REVENUE RECOGNITION

Our revenue is recognized when, or as, performance obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to a customer. We exclude sales, use, value-added, and other taxes we collect on behalf of third parties from revenue. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or services to a customer. To accurately present the consideration received in exchange for promised products or services, we apply the five-step model outlined below:

1.Identification of a contract or agreement with a customer

2.Identification of our performance obligations in the contract or agreement

3.Determination of the transaction price

4.Allocation of the transaction price to the performance obligations

5.Recognition of revenue when, or as, we satisfy a performance obligation        

We enter into contracts where customers purchase combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. The timing of revenue recognition, billings, and cash collections results in accounts receivable, lease receivables, and contract assets as a result of revenue recognized in advance of billings, and contract liabilities or deferred revenue as a result of receiving consideration in advance of revenue recognition within our unaudited condensed consolidated balance sheet. Our general payment terms range from 30 to 60 days, with exceptions in certain geographies.

Contracts may be amended to account for changes in contract specifications and requirements. Contract modifications exist when the amendment either creates new, or changes existing, enforceable rights and obligations. A modification is considered to be a separate contract, and revenue is recognized prospectively, when the modification creates new performance obligations to deliver additional goods or services and the related increase in consideration approximates the standalone selling price for the additional goods or services. If a contract modification does not create a new performance obligation to deliver new goods and/or services but the goods and/or services to be delivered after the contract modification date are distinct from the goods and/or services delivered on or before the contract modification date, then this contract modification is not accounted for as a separate contract, and we account for the goods and/or services to be delivered after the contract modification date prospectively. We account for a contract modification as if it were a part of the existing contract if the remaining goods or services are not distinct and, therefore, form part of a single performance obligation that is partially satisfied at the date of the contract modification. The effect that these contract modifications have on the transaction price, and on our measure of progress toward complete satisfaction of the performance obligation, is recognized as an adjustment to revenue at the date of the contract modification, with the adjustment to revenue made on a cumulative catch-up basis.

Below is a listing of our major categories of revenue for our products and services:

Diagnostic Products and Accessories. Diagnostic products and accessories revenues, including IDEXX VetLab® consumables and accessories, rapid assay, LPD, Water, and OPTI testing products, are predominantly recognized and invoiced at the time of shipment, which is when the customer obtains control of the product based on legal title transfer and we have the right to payment. We also provide customers with certain consumables that are recognized upon utilization by the customer, which is when we have the right to payment and the risks and rewards of ownership transfer. Shipping costs reimbursed by the customer are included in revenue and cost of sales. As a practical expedient, we do not account for shipping activities as a separate performance obligation.

Laboratory Diagnostic and Consulting Services. Laboratory diagnostic and consulting services revenues are recognized and invoiced when the laboratory diagnostic service is performed.

Instruments, Software and Systems. CAG Diagnostics capital instruments, veterinary software, and diagnostic imaging systems revenues are recognized and invoiced when the customer obtains control of the products based on legal title transfer and we have the right to payment, which generally occurs at the time of installation and customer acceptance. Our instruments, software, and systems are often included in one of our significant customer programs, as further described below. For veterinary software systems that include multiple performance obligations, such as perpetual software licenses and computer hardware, we allocate revenue to each performance obligation based on estimates of the price that we would charge the customer for each promised product or service if it were sold on a standalone basis.

Lease Revenue. Revenues from instrument rental agreements and reagent rental programs are recognized either as operating leases on a ratable basis over the term of the agreement or as sales-type leases at the time of installation and customer acceptance. Customers typically pay for the right to use instruments under rental agreements in equal monthly amounts over the term of the rental agreement. Our reagent rental programs provide our customers the right to use our instruments upon entering into multi-year agreements to purchase annual minimum amounts of consumables. These types of agreements include an embedded lease for the right to use our instruments. For some agreements, the customers are provided with the right to purchase the instrument at the end of the lease term. Lease revenues from these agreements are presented in product revenue on our unaudited condensed consolidated income statement. Lease revenue was approximately $5.5 million and $10.0 million for the three and six months ended June 30, 2023, respectively, as compared to $4.9 million and $9.9 million for the three and six months ended June 30, 2022, respectively, including both operating leases and sales-type leases under ASC 842, Leases, for leases entered into after January 1, 2019, and ASC 840, “Leases,” for leases entered into prior to 2019. Refer to below for revenue recognition under our reagent rental programs.

Extended Warranties and Post-Contract Support. CAG Diagnostics capital instruments and diagnostic imaging systems extended warranties typically provide customers with continued coverage for a period of one to five years beyond the first-year standard warranty. Customers can either pay in full for the extended warranty at the time of instrument or system

purchase or can be billed on a quarterly basis over the term of the contract. We recognize revenue associated with extended warranties over time on a ratable basis using a time-elapsed measure of performance over the contract term, which approximates the expected timing in which applicable services are performed.

Veterinary software post-contract support provides customers with access to technical support when and as needed through access to call centers and online customer assistance. Post-contract support contracts typically have a term of 12 months and customers are billed for post-contract support in equal quarterly amounts over the term. We recognize revenue for post-contract support services over time on a ratable basis using a time-elapsed measure of performance over the contract term, which approximates the expected timing in which applicable services are performed.

On December 31, 2022, our deferred revenue related to extended warranties and post-contract support was $26.4 million, of which approximately $1.8 million and $16.9 million were recognized during the three and six months ended June 30, 2023, respectively. Furthermore, as a result of new agreements, our deferred revenue related to extended warranties and post-contract support was $25.9 million as of June 30, 2023. We do not disclose information about remaining performance obligations that are part of contracts with an original expected duration of one year or less and do not adjust for the effect of the financing components when the period between customer payment and revenue recognition is one year or less. Deferred revenue related to extended warranties and post-contract support with an original duration of more than one year was $10.0 million as of June 30, 2023, of which approximately 24%, 37%, 21%, 9%, and 9% are expected to be recognized during the remainder of 2023, the full years 2024, 2025, 2026, and thereafter, respectively. Additionally, we have determined these agreements do not include a significant financing component.

SaaS Subscriptions. We offer a variety of veterinary software and diagnostic imaging SaaS subscriptions including ezyVet®, Animana®, Neo®, Cornerstone® Cloud, Pet Health Network® Pro, Petly® Plans, Web PACS, rVetLink®, and Smart Flow™. We recognize revenue for our SaaS subscriptions over time on a ratable basis over the contract term, beginning on the date our service is made available to the customer. Our subscription contracts vary in term from monthly to two years. Customers typically pay for our subscription contracts in equal monthly amounts over the term of the agreement. Deferred revenue related to our SaaS subscriptions is not material.

Contracts with Multiple Performance Obligations. We enter into contracts with multiple performance obligations where customers purchase a combination of IDEXX products and services. Determining whether products and services are considered distinct performance obligations that should be accounted for separately requires significant judgment. We determine the transaction price for a contract based on the total consideration we expect to receive in exchange for the transferred goods or services. To the extent the transaction price includes variable consideration, such as volume rebates or expected price adjustments, we apply judgment in constraining the estimated variable consideration due to factors that may cause reversal of revenue recognized. We evaluate constraints based on our historical and projected experience with similar customer contracts.

We allocate revenue to each performance obligation in proportion to the relative standalone selling prices, and recognize revenue when transfer of the related goods or services has occurred for each obligation. We utilize the observable standalone selling price when available, which represents the price charged for the promised product or service when sold separately. When standalone selling prices for our products or services are not directly observable, we determine the standalone selling prices using relevant information available and apply suitable estimation methods including, but not limited to, the cost plus a margin approach. We recognize revenue as each performance obligation is satisfied, either at a point in time or over time, as described in the revenue categories above. We do not disclose information about remaining performance obligations that are part of contracts with an original expected duration of one year or less.

The following customer programs represent our most significant customer contracts that contain multiple performance obligations:

Customer Commitment Programs. We offer customer incentives upon entering into multi-year agreements to purchase annual minimum amounts of products and services.

Up-Front Customer Loyalty Programs. Our up-front loyalty programs provide customers with incentives in the form of cash payments or IDEXX Points upon entering into multi-year agreements to purchase annual minimum amounts of future products or services. If a customer breaches their agreement, they are required to refund all or a portion of the up-front cash or IDEXX Points, or make other repayments, remedial actions, or both. Up-front incentives to customers in the form of cash or IDEXX Points are not made in exchange for distinct goods or services and are capitalized as customer acquisition costs within other current and long-term assets, which are subsequently recognized as a reduction to revenue over the term of

the customer agreement. If these up-front incentives are subsequently utilized to purchase instruments, we allocate total consideration, including future committed purchases less up-front incentives and estimates of expected price adjustments, based on relative standalone selling prices to identified performance obligations and recognize instrument revenue and cost at the time of installation and customer acceptance. To the extent invoiced instrument revenue exceeds recognized instrument revenue, we record deferred revenue as a contract liability, which is subsequently recognized upon the purchase of products and services over the term of the contract. We have determined these agreements do not include a significant financing component. Differences between estimated and actual customer purchases may impact the timing and amount of revenue recognition.

On December 31, 2022, our capitalized customer acquisition costs were $158.0 million, of which approximately $13.0 million and $26.4 million were recognized as a reduction of revenue during the three and six months ended June 30, 2023, respectively. Furthermore, as a result of new up-front customer loyalty payments, net of subsequent recognition, our capitalized customer acquisition costs were $162.6 million as of June 30, 2023. We monitor customer purchases over the term of their agreement to assess the realizability of our capitalized customer acquisition costs and review estimates of variable consideration. Impairments and revenue adjustments that relate to performance obligations satisfied in prior periods, including cumulative catch-up adjustments to revenue arising from contract modifications during the three and six months ended June 30, 2023, were not material.

Volume Commitment Programs. Our volume commitment programs, such as our IDEXX 360 program, provide customers with free or discounted instruments or systems upon entering into multi-year agreements to purchase annual minimum amounts of products and services. We allocate total consideration, including future committed purchases and expected price adjustments, based on relative standalone selling prices to identified performance obligations and recognize instrument revenue and cost at the time of installation and customer acceptance in advance of billing the customer, which is also when the customer obtains control of the instrument based on legal title transfer. Our right to future consideration related to instrument revenue is recorded as a contract asset within other current and long-term assets. The contract asset is transferred to accounts receivable when customers are billed for future products and services over the term of the contract. We have determined these agreements do not include a significant financing component. Differences between estimated and actual customer purchases may impact the timing and amount of revenue recognition.

On December 31, 2022, our volume commitment contract assets were $190.8 million, of which approximately $10.9 million and $22.0 million were reclassified to accounts receivable when customers were billed for related products and services during the three and six months ended June 30, 2023, respectively. Furthermore, as a result of new placements under volume commitment programs, net of subsequent amounts reclassified to accounts receivable, and allowances established for credit losses, our volume commitment contract assets were $207.9 million as of June 30, 2023. We monitor customer purchases over the term of their agreement to assess the realizability of our contract assets and review estimates of variable consideration. Impairments and revenue adjustments that relate to performance obligations satisfied in prior periods, including cumulative catch-up adjustments to revenue arising from contract modifications during the three and six months ended June 30, 2023, were not material.

For our up-front customer loyalty and volume commitment programs, we estimate future revenues related to multi-year agreements to be approximately $3.0 billion, of which approximately 15%, 27%, 22%, 18%, and 18% are expected to be recognized during the remainder of 2023, the full years 2024, 2025, 2026, and thereafter, respectively. These future revenues relate to performance obligations not yet satisfied, for which customers have committed to future purchases, net of the expected revenue reductions from customer acquisition costs and expected price adjustments, and, as a result, are lower than stated contractual commitments by our customers.

Instrument Rebate Programs. Our instrument rebate programs require an instrument purchase and provide customers the opportunity to earn future rebates based on the volume of products and services they purchase over the term of the program. We account for the customer’s right to earn rebates on future purchases as a separate performance obligation and determine the standalone selling price based on an estimate of rebates the customer will earn over the term of the program. Total consideration allocated to identified performance obligations is limited to goods and services that the customer is presently obligated to purchase and does not include estimates of future purchases that are optional. We allocate total consideration to identified performance obligations, including the customer’s right to earn rebates on future purchases, which is deferred and subsequently recognized upon the purchase of products and services, partly offsetting rebates as they are earned.

On December 31, 2022, our deferred revenue related to instrument rebate programs was $25.6 million, of which approximately $2.4 million and $5.0 million were recognized when customers purchased eligible products and services and earned rebates during the three and six months ended June 30, 2023, respectively. Furthermore, as a result of new instrument purchases under rebate programs, net of subsequent recognition, our deferred revenue was $23.7 million as of June 30, 2023, of which approximately 19%, 29%, 22%, 15%, and 15% are expected to be recognized during the remainder of 2023, the full years 2024, 2025, 2026, and thereafter, respectively.

Reagent Rental Programs. Our reagent rental programs provide our customers the right to use our instruments upon entering into multi-year agreements to purchase annual minimum amounts of consumables. These types of agreements include an embedded lease for the right to use our instrument, and we determine the amount of lease revenue allocated to the instrument based on relative standalone selling prices. We evaluate the terms of these embedded leases to determine classification as either a sales-type lease or an operating lease.

Sales-type Reagent Rental Programs. Our reagent rental programs that effectively transfer control of instruments to our customers are classified as sales-type leases, and we recognize instrument revenue and cost in advance of billing the customer, at the time of installation and customer acceptance. Our right to future consideration related to instrument revenue is recorded as a lease receivable within other current and long-term assets, and is transferred to accounts receivable when customers are billed for future products and services over the term of the contract. On December 31, 2022, our lease receivable assets were $18.4 million, of which approximately $1.1 million and $2.2 million were reclassified to accounts receivable when customers were billed for related products and services during the three and six months ended June 30, 2023, respectively. Furthermore, as a result of new placements under sales-type reagent rental programs, net of subsequent amounts reclassified to accounts receivable, and allowances established for credit losses, our lease receivable assets were $19.7 million as of June 30, 2023. The impacts of discounting and unearned income as of June 30, 2023 were not material. Profit and loss recognized at the commencement date and interest income during the three and six months ended June 30, 2023, were not material. We monitor customer purchases over the term of their agreement to assess the realizability of our lease receivable assets. Impairments during the three and six months ended June 30, 2023 were not material.

Operating-type Reagent Rental Programs. Our reagent rental programs that do not effectively transfer control of instruments to our customers are classified as operating leases, and we recognize instrument revenue and costs ratably over the term of the agreement. The cost of the instrument is capitalized within property and equipment. During the three and six months ended June 30, 2023, we transferred instruments of $4.8 million and $8.6 million, respectively, as compared to $4.6 million and $7.6 million for the three and six months ended June 30, 2022, respectively, from inventory to property and equipment.

We estimate future revenue to be recognized related to our reagent rental programs of approximately $47.8 million, of which approximately 13%, 25%, 21%, 16%, and 25% are expected to be recognized during the remainder of 2023, the full years 2024, 2025, 2026, and thereafter, respectively. These future revenues relate to performance obligations not yet satisfied for which customers have committed to future purchases, net of any expected price adjustments, and, as a result, may be lower than stated contractual commitments by our customers.

Other Customer Incentive Programs. Certain agreements with customers include discounts or rebates on the sale of products and services applied retrospectively, such as volume rebates achieved by purchasing a specified purchase threshold of goods and services. We account for these discounts as variable consideration and estimate the likelihood of a customer meeting the threshold in order to determine the transaction price using the most predictive approach. We typically use the most-likely-amount method for incentives that are offered to individual customers and the expected-value method for programs that are offered to a broad group of customers. Revenue adjustments that relate to performance obligations satisfied in prior periods, including cumulative catch-up adjustment to revenue arising from contract modifications, during the three and six months ended June 30, 2023, were not material. Refund obligations related to customer incentive programs are recorded in accrued liabilities for the actual issuance of incentives, incentives earned but not yet issued, and estimates of incentives to be earned in the future.

Program Combinations. At times, we combine elements of our significant customer programs within a single customer contract. We separate each significant program element and include the contract assets, customer acquisition costs, deferred revenues, and estimated future revenues within the most relevant program disclosures above. Each customer contract is presented as a net contract asset or net contract liability on our unaudited condensed consolidated balance sheet.

IDEXX Points. IDEXX Points may be applied to trade receivables due to us, converted to cash, or applied against the purchase price of IDEXX products and services. We consider IDEXX Points equivalent to cash. IDEXX Points that have not yet been used by customers are included in accrued liabilities until utilized or expired. Breakage is not material because customers can apply IDEXX Points to trade receivables at any time.

Accounts Receivable. We recognize revenue when it is probable that we will collect substantially all of the consideration to which we will be entitled, based on the customer’s intent and ability to pay the promised consideration. We apply judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the customer. Concentrations of credit risk with respect to accounts receivable are limited due to the large number of customers that purchase our products and services, and we have no significant customers that accounted for greater than 10% of our consolidated revenues during the three and six months ended June 30, 2023.

Disaggregated Revenues. We present disaggregated revenue for our CAG segment based on major product and service categories. Our Water segment is comprised of a single major product category. Although our LPD segment does not meet the quantitative requirements to be reported as a separate segment, we believe it is important to disaggregate these revenues as a major product and service category separately from our Other reportable segment given its distinct markets, and therefore we have elected to report LPD as a reportable segment.

The following table presents disaggregated revenue by major product and service categories:

Costs to Obtain a Contract. We capitalize sales commissions, and the related fringe benefits earned by our sales force when considered incremental, and recoverable costs of obtaining a contract. Our contracts include performance obligations related to various goods and services, some of which are satisfied at a point in time and others over time. Commission costs related to performance obligations satisfied at a point in time are expensed at the time of sale, which is when revenue is recognized. Commission costs related to long-term service contracts and performance obligations satisfied over time, including extended warranties and SaaS subscriptions, are deferred and recognized on a systematic basis that is consistent with the

transfer of the goods or services to which the asset relates. We apply judgment in estimating the amortization period, which ranges from 3 to 7 years, by taking into consideration our customer contract terms, history of renewals, and expected length of customer relationship, as well as the useful life of the underlying technology and products. Amortization expense is included in sales and marketing expenses in the accompanying unaudited condensed consolidated statements of income. Deferred commission costs are periodically reviewed for impairment.

On December 31, 2022, our deferred commission costs, included within other assets, were $19.2 million, of which approximately $1.7 million and $3.4 million of commission expense was recognized during the three and six months ended, respectively. June 30, 2023. Furthermore, as a result of commissions related to new extended warranties and SaaS subscriptions, net of subsequent recognition, our deferred commission costs were $19.5 million as of June 30, 2023. Impairments of deferred commission costs during the three and six months ended June 30, 2023, were not material.

Business Combination and Asset Acquisition [Abstract]

Acquisitions, Asset Purchases and Investments

ACQUISITIONS, ASSET PURCHASES AND INVESTMENTS

We believe that our acquisitions of businesses and other assets enhance our existing businesses by either expanding our geographic range, customer base, or existing product and service lines. From time to time we may acquire small reference laboratories or radiology practices that we account for as either asset purchases or business combinations.

Asset Purchases and Investments

During the first quarter of 2022 we made a $10.0 million payment for a perpetual intellectual property license, which will be amortized over 10 years. The related amortization expense is recorded in our CAG segment.

During the second quarter of 2022, we entered into two discrete arrangements to license intellectual property for which we paid $65.0 million over the course of the 2022, and accrued $15.0 million in subsequent payments, all of which was charged to research and development expense. The $15.0 million milestone payment was made in the first quarter of 2023. These two arrangements were treated as asset acquisitions under U.S. GAAP and resulted in the full amount being expensed to research and development expense as in-process research and development costs with no alternative future use. The acquisition of these licensing arrangements supports new instrument platform advancements.

During the second quarter of 2022 we purchased $25.0 million of preferred shares for a noncontrolling minority interest in one of the entities with which we have a license agreement. We elected to measure the investment as an equity security investment, under ASC 321, “Investment - Equity Securities,” and recorded the investment at cost.

Business Combinations

During the third quarter of 2022, we acquired the assets of an international water testing company located in Canada for approximately $12.8 million in cash, including a holdback of approximately $1.3 million. This acquisition expands our product offering in the Water segment. The fair values of the assets and liabilities acquired consists of technology intangibles of approximately $3.4 million, with a life of 10 years; customer relationship intangibles of approximately $1.2 million, with a life of 10 years; approximately $6.9 million of goodwill, representing synergies with our Water testing portfolio; and approximately $1.3 million of tangible assets, including inventory and accounts receivable. Goodwill related to this acquisition is expected to be deductible for tax purposes. Pro forma information has not been presented for this acquisition because such information is not material to the financial statements. The results of operations have been included in our Water segment since the acquisition date. The acquisition expenses were not material

Share-Based Compensation

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

SHARE-BASED COMPENSATION 

The fair value of options, restricted stock units, deferred stock units, and employee stock purchase rights awarded during the three and six months ended June 30, 2023, totaled $3.3 million and $60.6 million, respectively, as compared to $4.4 million and $55.4 million for the three and six months ended June 30, 2022, respectively. The total unrecognized compensation expense, net of estimated forfeitures, for unvested share-based compensation awards outstanding as of June 30, 2023, was $94.3 million, which will be recognized over a weighted average period of approximately 1.7 years. During the three and six months ended June 30, 2023, we recognized expenses of $15.4 million and $29.3 million, respectively, as compared to $12.3 million and $23.5 million for the three and six months ended June 30, 2022, respectively, related to share-based compensation.

We determine the assumptions used in the valuation of option awards as of the date of grant. Differences in the expected stock price volatility, expected term, or risk-free interest rate may necessitate 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 or greater than 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 intention to pay such a dividend at this time; 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 Six Months Ended June 30,
	2023			2022
Expected stock price volatility	32		%	30		%
Expected term, in years	6.7			6.4
Risk-free interest rate	3.7		%	2.0		%

Credit Loss [Abstract]

Credit Losses

CREDIT LOSSES  

We are exposed to credit losses primarily through our sales of products and services to our customers. We maintain allowances for credit losses for potentially uncollectible receivables. We base our estimates on a detailed analysis of specific customer situations and a percentage of our accounts receivable by aging category. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current economic conditions.

Additional allowances may be required if either the financial condition of our customers were to deteriorate, or a strengthening U.S. dollar impacts the ability of foreign customers to make payments to us on their U.S. dollar-denominated purchases. We monitor our ongoing credit exposure through active review of counterparty balances against contract terms and due dates. Our activities include timely account reconciliations, dispute resolution, and payment confirmations. We may employ collection agencies and legal counsel to pursue recovery of defaulted receivables.

Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered. We may require collateralized asset support or a prepayment to mitigate credit risk. We do not have any off-balance sheet credit exposure related to our customers.

Accounts Receivable

The allowance for credit losses associated with accounts receivable was $9.8 million and $8.3 million as of June 30, 2023 and December 31, 2022, respectively. The amount of accounts receivable reflected on the balance sheet is net of this reserve. Based on an aging analysis, as of June 30, 2023, approximately 89% of our accounts receivable had not yet reached the invoice due date, and approximately 11% was considered past due, of which less than 1% was greater than 60 days past due. As of December 31, 2022, approximately 86% of our accounts receivable had not yet reached the invoice due date, and approximately 14% was considered past due, of which approximately 2% was greater than 60 days past due.

Contract assets and lease receivables

The allowance for credit losses associated with the contract assets and lease receivables was $6.0 million and $5.5 million as of June 30, 2023 and December 31, 2022, respectively. The assets reflected on the balance sheet are net of these reserves. Historically, we have experienced low credit loss rates on our customer commitment programs and lease receivables. We apply judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the customer.

Credit Facility

As of June 30, 2023, we had $264.0 million in outstanding borrowings under our Credit Facility, which consisted of $14.0 million drawn under our line of credit and a $250.0 million Term Loan, with a weighted average effective interest rate of 6.3%, excluding any impact of our interest rate swap. As of December 31, 2022, we had $579.0 million in outstanding borrowings under our Credit Facility, which consisted of $329.0 million drawn under our line of credit and a $250.0 million Term Loan, with a weighted average effective interest rate of 5.1%. As of June 30, 2023, we had a remaining borrowing availability of $984.5 million under our $1.25 billion Credit Facility. The funds available under the Credit Facility reflect a further reduction due to the issuance of letters of credit, which were issued primarily in connection with our workers’ compensation policy, for $1.5 million.

The applicable interest rate for the Credit Facility is calculated at a per annum rate equal to either (at our option) (1) a prime rate plus a margin ranging from 0.0% to 0.375% based on our consolidated leverage ratio, (2) an adjusted term SOFR rate, plus 0.10%, plus a margin ranging from 0.875% to 1.375% based on our consolidated leverage ratio, or (3) an adjusted daily simple SOFR rate, plus 0.10%, plus a margin ranging from 0.875% to 1.375% based on our consolidated leverage ratio. In March 2023 we entered into an interest rate swap contract to manage the economic effect of $250 million of variable interest borrowings under our Credit Facility. Refer to Note 19 for a discussion of our derivative instruments and hedging activity.

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 sole financial covenant is a consolidated leverage ratio test that requires our ratio of debt to earnings before interest, taxes, depreciation, amortization, and share-based compensation defined as the consolidated leverage ratio under the terms of the Credit Facility, not to exceed 3.5-to-1. At June 30, 2023 and December 31, 2022, we were in compliance with the covenants of the Credit Facility.

INCOME TAXES 

Our effective income tax rate was 21.6% for the three months ended June 30, 2023, as compared to 22.9% for the three months ended June 30, 2022, and 20.8% for the six months ended June 30, 2023, as compared to 21.0% for the six months ended June 30, 2022. The decrease in our effective tax rate for the three and six months ended June 30, 2023, as compared to the same period in the prior year, was primarily driven by geographical income mix, partially offset by a decrease in the tax rate benefits related to share-based compensation.

The effective tax rate for the three and six months ended June 30, 2023, differed from the U.S. federal statutory tax rate of 21% primarily due to U.S. state income taxes, net of federal benefit, partially offset by taxes benefits from share-based compensation.

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income attributable to our stockholders by the weighted average number of shares of common stock and vested deferred stock units outstanding during the year. 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 treasury stock method assumes that proceeds, including cash received from the exercise of employee stock options and the total unrecognized compensation expense for unvested share-based compensation awards, would be used to purchase our common stock at the average market price 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. Refer to Note 5 to the consolidated financial statements in our 2022 Annual Report for additional information regarding deferred stock units.

The following is a reconciliation of weighted average shares outstanding for basic and diluted earnings per share:

(in thousands)	For the Three Months Ended June 30,		For the Six Months Ended June 30,
	2023	2022	2023	2022

COMMITMENTS, CONTINGENCIES AND GUARANTEES

Commitments

Refer to “Note 8. Leases,” for more information regarding our lease commitments.

Contingencies

We are subject to claims that may arise in the ordinary course of business, including with respect to actual and threatened litigation and other matters. We accrue for loss contingencies when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. However, the results of legal actions cannot be predicted with certainty, and therefore our actual losses with respect to these contingencies could exceed our accruals. Except for the litigation matter described below, as of June 30, 2023, our accruals with respect to actual and threatened litigation were not material.

We are a defendant in an ongoing litigation matter involving an alleged breach of contract for underpayment of royalty payments made from 2004 through 2017 under an expired patent license agreement. The plaintiff has asserted a claim of approximately $50 million, inclusive of interest through June 30, 2020, alleging that the incorrect royalty provision was applied to certain licensed products and services throughout the agreement term and that royalties were also due on non-licensed diagnostic services that were provided concurrently with licensed services. The trial court previously ruled in favor of the plaintiff in this matter. The appellate court reversed the trial court’s decision, and the plaintiff has petitioned the state supreme court for review. While we believe the claim is without merit and continue to vigorously defend ourselves against the plaintiff’s allegations, litigation is inherently unpredictable, and there can be no assurance that we will prevail in this matter. During the third quarter of 2020, we established an accrual of $27.5 million related to this ongoing matter, which represents the amount of the contingent loss that we have determined to be probable and estimable. We have not made any adjustments to this accrual since it was established. The actual cost of resolving this matter may be higher or lower than the amount we have accrued.

From time to time, we have received notices alleging that our products infringe third-party proprietary rights, although we are not aware of any pending litigation with respect to such claims. Patent litigation frequently is complex and expensive, and the outcome of patent litigation can be difficult to predict. There can be no assurance that we will prevail in any infringement proceedings that may be commenced against us. If we lose any such litigation, we may be stopped from selling certain products and/or we may be required to pay damages as a result of the litigation.

Guarantees

We enter into agreements with third parties in the ordinary course of business under which we are obligated to indemnify such third parties for and against various risks and losses. The precise terms of such indemnities vary with the nature of the agreement. In many cases, we limit the maximum amount of our indemnification obligations, but in some cases, those obligations may be theoretically unlimited. We have not incurred material expenses in discharging any of these indemnification obligations and, based on our analysis of the nature of the risks involved, we believe that the fair value of potential indemnification under these agreements is minimal. Accordingly, we have recorded no liabilities for these obligations as of June 30, 2023 and December 31, 2022.

Segment Reporting [Abstract]

Segment Reporting

SEGMENT REPORTING

We operate primarily through three business segments: Companion Animal Group (“CAG”), Water quality products (“Water”), and Livestock, Poultry and Dairy (“LPD”). CAG provides products and services for veterinarians and the biomedical research community, primarily related to diagnostics and information management. Water provides innovative testing solutions for the detection and quantification of various microbiological parameters in water. LPD provides diagnostic tests, services, and related instrumentation that are used to manage the health status of livestock and poultry, to improve producer efficiency, and to ensure the quality and safety of milk. Our Other operating segment combines and presents our human medical diagnostic business (“OPTI Medical”) with our out-licensing arrangements because they do not meet the quantitative or qualitative thresholds for reportable segments. OPTI Medical develops, manufactures, and distributes human medical diagnostic products and provides human medical diagnostic services. 

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker (“CODM”), or decision-making group, in deciding how to allocate resources and in assessing performance. Our CODM is our Chief Executive Officer. Our reportable segments include: CAG, Water, LPD, and Other. Assets are not allocated to segments for internal reporting purposes.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

FAIR VALUE MEASUREMENTS 

U.S. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value.

We have certain financial assets and liabilities that are measured at fair value on a recurring basis, certain nonfinancial assets and liabilities that may be measured at fair value on a non-recurring basis, and certain financial assets and liabilities that are not measured at fair value in our unaudited condensed consolidated balance sheets but for which we disclose the fair value.

The fair value disclosures of these assets and liabilities are based on a three-level hierarchy, which is defined as follows: 

Level 1	Quoted prices in active markets for identical assets or liabilities that the entity can 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.
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.

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 transfers between Level 1 and Level 2, or transfers in or out of Level 3, of the fair value hierarchy during the three and six months ended June 30, 2023.

Our cross currency swap contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets. We measure the fair value of our cross currency swap contracts classified as derivative instruments using prevailing market conditions as of the close of business on each balance sheet date. The product of this calculation is then adjusted for counterparty risk.

Our foreign currency exchange contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets. We measure the fair value of our foreign currency exchange contracts classified as derivative instruments using an income approach, based on prevailing market forward rates less the contract rate multiplied by the notional amount. The product of this calculation is then adjusted for counterparty risk.

Our interest rate swap contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets. We measure the fair value of our interest rate swap contracts classified as derivative instruments using current market interest rates for debt issues with similar remaining years to maturity, adjusted for applicable credit risk.

The amounts outstanding under our unsecured credit facility (“Credit Facility”) and senior notes (“long-term debt”) are measured at carrying value in our unaudited condensed consolidated balance sheets though we disclose the fair value of these financial instruments. We determine the fair value of the amount outstanding under our Credit Facility and long-term debt using an income approach, utilizing a discounted cash flow analysis based on current market interest rates for debt issues with similar remaining years to maturity, adjusted for applicable credit risk. Our Credit Facility and long-term debt are valued using Level 2 inputs. The estimated fair value of our Credit Facility approximates its carrying value. The estimated fair value and carrying value of our long-term debt were $730.1 million and $772.2 million, respectively, as of June 30, 2023, and $725.6 million and $769.8 million, respectively, as of December 31, 2022.

(1)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. Refer to footnote (4) below for a discussion of the related deferred compensation liability. 

(2)Cross currency swaps and foreign currency exchange contracts are included within other current assets, other long-term assets, accrued liabilities, or other long-term liabilities depending on the gain (loss) position and anticipated settlement date.  

(3)Interest rate swap is included within other long-term liabilities.

(4)A deferred compensation plan assumed as part of a previous business combination is included within accrued liabilities and 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 footnote (1) above.

The estimated fair values of certain financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, approximate their respective carrying values due to their short maturity.

Contingent Consideration

We have classified our liabilities for contingent consideration related to acquisitions within Level 3 of the fair value hierarchy because the fair value is determined using significant unobservable inputs, which includes the achievements of future revenues. The contingent consideration is included within other short-term liabilities.

We record changes in the estimated fair value of contingent consideration in the unaudited condensed consolidated statements of income. Changes in contingent consideration liabilities are measured at fair value on a recurring basis using unobservable inputs (Level 3) and during the three and six months ended June 30, 2023, are as follows:

Hedging Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Hedging Instruments

HEDGING INSTRUMENTS

Disclosure within this note is presented to provide transparency about how and why we use derivative and non-derivative instruments (collectively “hedging 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.

We are exposed to certain risks related to our ongoing business operations. We utilize hedging instrument to manage a portion our foreign currency exchange risk and interest rate risk. During the first quarter of 2023, we entered into an interest rate swap to manage the impact of interest rate fluctuations associated with $250.0 million of borrowings under our variable-rate Credit Facility. We have designated the interest rate swap as a cash flow hedge.

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 other foreign currency exchange contracts, cross currency swaps, or foreign-denominated debt issuances to minimize the impact of foreign currency fluctuations associated with specific balance sheet exposures, including net investments in certain foreign subsidiaries.  

The primary purpose of our foreign currency hedging activities is to protect against the volatility associated with foreign currency transactions, including transactions denominated in the euro, British pound, Japanese yen, Canadian dollar, and Australian dollar. 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 foreign currency exchange contracts with well-capitalized 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.

We recognize all hedging instrument assets and liabilities at fair value at the balance sheet date. Instruments that do not qualify for hedge accounting treatment are recorded at fair value through earnings. To qualify for hedge accounting treatment, cash flow and net investment hedges must be highly effective in offsetting changes to expected future cash flows or fair value on hedged transactions. If the instrument qualifies for hedge accounting, changes in the fair value of the hedging instrument from the effective portion of the hedge are deferred in AOCI, net of tax, and 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 hedging instrument is not effective in achieving offsetting changes in fair value. We de-designate hedging instruments from hedge accounting when the likelihood of the hedged transaction occurring becomes less than probable. 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 AOCI at the time of de-designation is reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Refer to “Note 14. Accumulated Other Comprehensive Income” for further information regarding the effect of hedging instruments on our unaudited condensed consolidated statements of income for the three and six months ended June 30, 2023 and 2022.

We enter into master netting arrangements with the counterparties to our derivative transactions, which permit certain outstanding receivables and payables to be offset in the event of default. Our derivative contracts do not require either party to post cash collateral. We elect to present our derivative assets and liabilities in the unaudited condensed consolidated balance sheets on a gross basis. All cash flows related to our foreign currency exchange contracts are classified as operating cash flows, which is consistent with the cash flow treatment of the underlying items being hedged. 

Cash Flow Hedges 

We have designated our foreign currency exchange contracts and our interest rate swap as cash flow hedges as these derivative instruments manage our exposure to variability in the cash flows of forecasted transactions attributable to foreign currency exchange and interest rates on variable interest obligations under the terms of our Credit Facility. Unless noted otherwise, we have also designated our derivative instruments as qualifying for hedge accounting treatment.  

We did not de-designate any instruments from hedge accounting treatment during either the three and six months ended June 30, 2023 or 2022. As of June 30, 2023, the estimated amount of net gains, net of tax, from our foreign currency exchange contracts which are expected to be reclassified out of AOCI and into earnings within the next 12 months, is $0.6 million if exchange rates do not fluctuate from the levels as of June 30, 2023. 

Foreign Currency Exchange Contracts: We target to hedge approximately 75% to 85% of the estimated exposure from intercompany product purchases and sales denominated in the euro, British pound, Canadian dollar, Japanese yen, and Australian dollar. We have additional unhedged foreign currency exposures related to foreign services and emerging markets where it is not practical to hedge. We primarily utilize foreign currency exchange contracts with durations of less than 24 months. Quarterly, we enter into contracts to hedge incremental portions of anticipated foreign currency transactions for the current and following year. As a result, our risk with respect to foreign currency exchange rate fluctuations and the notional value of foreign currency exchange contracts may vary throughout the year. The U.S. dollar is the currency purchased or sold in all of our foreign currency exchange contracts. The notional amount of foreign currency exchange contracts to hedge forecasted intercompany inventory purchases and sales totaled $247.9 million and $258.2 million as of June 30, 2023 and December 31, 2022, respectively.

Interest Rate Swap: We entered into an interest rate swap contract to manage the economic effect of variable interest obligations on amounts borrowed under the terms of the Credit Facility. Beginning on March 31, 2023, the variable interest rate associated with $250.0 million of borrowings outstanding under the Credit Facility became effectively fixed at 3.9% plus the applicable credit spread, through October 20, 2025.

The following table presents the effect of cash flow hedge accounting on our unaudited condensed consolidated statements of income and comprehensive income, and provides information regarding the location and amounts of pretax gains or losses of derivatives:

Net Investment Hedges, Euro-Denominated Notes

In June 2015, we issued and sold through a private placement an aggregate principal amount of €88.9 million in euro-denominated 1.785% Series C Senior Notes due June 18, 2025. We have designated these euro-denominated notes as a hedge of our euro net investment in certain foreign subsidiaries to reduce the volatility in stockholders’ equity caused by changes in foreign currency exchange rates in the euro relative to the U.S. dollar. As a result of this designation, gains and losses from the change in translated U.S. dollar value of these euro-denominated notes are recorded in AOCI rather than to earnings. We recorded losses of $0.4 million and $1.8 million, net of tax, within AOCI as a result of this net investment hedge for the three and six months ended June 30, 2023, respectively, and gains of $4.1 million and $5.5 million for the three and six months ended June 30, 2022, respectively. The related cumulative unrealized gain recorded as of June 30, 2023, will be reclassified to earnings when the foreign subsidiaries are sold or substantially liquidated or all or a portion of the hedge no longer qualifies for hedge accounting treatment. Refer to Note 13 to the consolidated financial statements included in our 2022 Annual Report for further information regarding the issuance of these euro-denominated notes.

Net Investment Hedges, Cross Currency Swaps

We have entered into several cross currency swap contracts as a hedge of our net investment in foreign operations to offset foreign currency translation gains and losses on the net investment. These cross currency swaps have maturity dates beginning on June 30, 2025, through June 30, 2028. At maturity of the cross currency swap contracts we will deliver the notional amount of €15 million and will receive approximately $17.5 million from the counterparties on June 18, 2025; we will deliver the notional amount of €35 million and will receive $37.8 million from the counterparties on March 31, 2028; and we will deliver the notional amount of €90 million and will receive $98.2 million from the counterparties on June 30, 2028. The changes in fair value of the cross currency swap contracts are recorded in AOCI and will be reclassified to earnings when the foreign subsidiaries are sold or substantially liquidated. During the three and six months ended June 30, 2023, we recorded losses of $1.8 million and $3.0 million, net of tax, respectively, within AOCI as a result of these net investment hedges, and gains of $4.3 million and gains of $5.3 million during the three and six months ended June 30, 2022, respectively. We will receive quarterly interest payments from the counterparties based on a fixed interest rate until maturity of the cross currency swaps. This interest rate component is excluded from the assessment of hedge effectiveness and is recognized as a reduction to interest expense over the life of the hedge instrument. We recognized approximately $0.8 million and $1.5 million related to the excluded component as a reduction of interest expense for the three and six months ended June 30, 2023, respectively, and $0.7 million and $1.4 million and for the three and six months ended June 30, 2022, respectively.

During the second quarter of 2023, the notional amount of €90.0 million in cross currency swaps matured, resulting in a net cash receipt of $6.3 million. The receipt of cash is reflected within financing activities on the Condensed Consolidated Statements of Cash Flows.

Accounting Policies [Abstract]

Accounts Payable - Supplier Financing Program

Accounts Payable - Supplier Financing ProgramWe have an agreement with a third party to provide a supplier finance program, which facilitates participating suppliers’ ability to finance payment obligations from us with a designated third-party financial institution. Participating suppliers may, at their sole discretion, make offers to finance one or more of our payment obligations prior to their scheduled due dates at a discounted price. Our obligations to our suppliers, including amounts due and scheduled payment dates, are not impacted by suppliers’ decisions to finance amounts under these arrangements. The terms of payments are in-line with the terms of our trade payables. Activity related to the obligations is presented within operating activities on the unaudited consolidated statements of cash flows.

New Accounting Pronouncements Adopted

New Accounting Pronouncements Adopted

We adopted ASU 2022-04, “Liabilities - Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations,” as of January 1, 2023, which adds certain disclosure requirements for a buyer in a supplier finance program. The amendments in this update require that a buyer in a supplier finance program discloses sufficient information about the program to allow a user of financial statements to understand the program's nature, activity during the period, changes from period to period, and potential magnitude.

We adopted ASU 2021-08, “Business Combinations (Topic 805): Accounting for Acquired Contract Assets and Contract Liabilities,” as of January 1, 2023. ASU 2021-08 is intended to improve comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of and after a business combination by providing consistent recognition guidance. The adoption of ASU 2021-08 did not have a material impact on our unaudited condensed consolidated financial statements.

Revenue Recognition

Our revenue is recognized when, or as, performance obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to a customer. We exclude sales, use, value-added, and other taxes we collect on behalf of third parties from revenue. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or services to a customer. To accurately present the consideration received in exchange for promised products or services, we apply the five-step model outlined below:

1.Identification of a contract or agreement with a customer

2.Identification of our performance obligations in the contract or agreement

3.Determination of the transaction price

4.Allocation of the transaction price to the performance obligations

5.Recognition of revenue when, or as, we satisfy a performance obligation

Share-based Compensation

We determine the assumptions used in the valuation of option awards as of the date of grant. Differences in the expected stock price volatility, expected term, or risk-free interest rate may necessitate 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 or greater than 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 intention to pay such a dividend at this time; therefore, we assume that no dividends will be paid over the expected terms of option awards.

Credit Losses

We are exposed to credit losses primarily through our sales of products and services to our customers. We maintain allowances for credit losses for potentially uncollectible receivables. We base our estimates on a detailed analysis of specific customer situations and a percentage of our accounts receivable by aging category. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current economic conditions.

Additional allowances may be required if either the financial condition of our customers were to deteriorate, or a strengthening U.S. dollar impacts the ability of foreign customers to make payments to us on their U.S. dollar-denominated purchases. We monitor our ongoing credit exposure through active review of counterparty balances against contract terms and due dates. Our activities include timely account reconciliations, dispute resolution, and payment confirmations. We may employ collection agencies and legal counsel to pursue recovery of defaulted receivables.

Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered. We may require collateralized asset support or a prepayment to mitigate credit risk. We do not have any off-balance sheet credit exposure related to our customers.

Inventories

Inventories are stated at the lower of cost (first-in, first-out) or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.

Earnings Per Share

Basic earnings per share is computed by dividing net income attributable to our stockholders by the weighted average number of shares of common stock and vested deferred stock units outstanding during the year. 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 treasury stock method assumes that proceeds, including cash received from the exercise of employee stock options and the total unrecognized compensation expense for unvested share-based compensation awards, would be used to purchase our common stock at the average market price 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.

Fair Value Measurements

U.S. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value.

We have certain financial assets and liabilities that are measured at fair value on a recurring basis, certain nonfinancial assets and liabilities that may be measured at fair value on a non-recurring basis, and certain financial assets and liabilities that are not measured at fair value in our unaudited condensed consolidated balance sheets but for which we disclose the fair value.

The fair value disclosures of these assets and liabilities are based on a three-level hierarchy, which is defined as follows: 

Level 1	Quoted prices in active markets for identical assets or liabilities that the entity can 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.
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.

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 transfers between Level 1 and Level 2, or transfers in or out of Level 3, of the fair value hierarchy during the three and six months ended June 30, 2023.

Our cross currency swap contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets. We measure the fair value of our cross currency swap contracts classified as derivative instruments using prevailing market conditions as of the close of business on each balance sheet date. The product of this calculation is then adjusted for counterparty risk.

Our foreign currency exchange contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets. We measure the fair value of our foreign currency exchange contracts classified as derivative instruments using an income approach, based on prevailing market forward rates less the contract rate multiplied by the notional amount. The product of this calculation is then adjusted for counterparty risk.

Our interest rate swap contracts are measured at fair value on a recurring basis in our accompanying unaudited condensed consolidated balance sheets. We measure the fair value of our interest rate swap contracts classified as derivative instruments using current market interest rates for debt issues with similar remaining years to maturity, adjusted for applicable credit risk.

The amounts outstanding under our unsecured credit facility (“Credit Facility”) and senior notes (“long-term debt”) are measured at carrying value in our unaudited condensed consolidated balance sheets though we disclose the fair value of these financial instruments. We determine the fair value of the amount outstanding under our Credit Facility and long-term debt using an income approach, utilizing a discounted cash flow analysis based on current market interest rates for debt issues with similar remaining years to maturity, adjusted for applicable credit risk. Our Credit Facility and long-term debt are valued using Level 2 inputs. The estimated fair value of our Credit Facility approximates its carrying value.

Hedging Instruments

We are exposed to certain risks related to our ongoing business operations. We utilize hedging instrument to manage a portion our foreign currency exchange risk and interest rate risk. During the first quarter of 2023, we entered into an interest rate swap to manage the impact of interest rate fluctuations associated with $250.0 million of borrowings under our variable-rate Credit Facility. We have designated the interest rate swap as a cash flow hedge.

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 other foreign currency exchange contracts, cross currency swaps, or foreign-denominated debt issuances to minimize the impact of foreign currency fluctuations associated with specific balance sheet exposures, including net investments in certain foreign subsidiaries.  

The primary purpose of our foreign currency hedging activities is to protect against the volatility associated with foreign currency transactions, including transactions denominated in the euro, British pound, Japanese yen, Canadian dollar, and Australian dollar. 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 foreign currency exchange contracts with well-capitalized 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.

We recognize all hedging instrument assets and liabilities at fair value at the balance sheet date. Instruments that do not qualify for hedge accounting treatment are recorded at fair value through earnings. To qualify for hedge accounting treatment, cash flow and net investment hedges must be highly effective in offsetting changes to expected future cash flows or fair value on hedged transactions. If the instrument qualifies for hedge accounting, changes in the fair value of the hedging instrument from the effective portion of the hedge are deferred in AOCI, net of tax, and 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 hedging instrument is not effective in achieving offsetting changes in fair value. We de-designate hedging instruments from hedge accounting when the likelihood of the hedged transaction occurring becomes less than probable. 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 AOCI at the time of de-designation is reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Refer to “Note 14. Accumulated Other Comprehensive Income” for further information regarding the effect of hedging instruments on our unaudited condensed consolidated statements of income for the three and six months ended June 30, 2023 and 2022.

We enter into master netting arrangements with the counterparties to our derivative transactions, which permit certain outstanding receivables and payables to be offset in the event of default. Our derivative contracts do not require either party to post cash collateral. We elect to present our derivative assets and liabilities in the unaudited condensed consolidated balance sheets on a gross basis. All cash flows related to our foreign currency exchange contracts are classified as operating cash flows, which is consistent with the cash flow treatment of the underlying items being hedged. 

Cash Flow Hedges We have designated our foreign currency exchange contracts and our interest rate swap as cash flow hedges as these derivative instruments manage our exposure to variability in the cash flows of forecasted transactions attributable to foreign currency exchange and interest rates on variable interest obligations under the terms of our Credit Facility. Unless noted otherwise, we have also designated our derivative instruments as qualifying for hedge accounting treatment.
