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 consolidated balance sheet data at December 31, 2018, 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, 2019, 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, 2019, and our Annual Report on Form 10-K for the year ended December 31, 2018, (the “2018 Annual Report”) filed with the SEC.

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 for the three and six months ended June 30, 2019, are consistent with those discussed in Note 2 to the consolidated financial statements in our 2018 Annual Report, except as noted below.

New Accounting Pronouncements Adopted

We adopted ASU 2016-02, Leases (Topic 842) (the "New Leasing Standard"), as of January 1, 2019, using the optional transition method that allows for a cumulative-effect adjustment in the period of adoption and did not restate prior periods. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification. The adoption of the New Leasing Standard resulted in the recording of operating lease liabilities of $86.7 million and right-of-use assets of $83.7 million. Prior to our adoption of the New Leasing Standard, rent prepayments of approximately $1.0 million were recorded within other current assets and the impact of recognizing rent expense on a straight-line basis of approximately $4.0 million was recorded within other current and long-term liabilities. Upon adoption of the New Leasing Standard, these rent prepayments and straight-line rent impacts are now recorded within operating lease right-of-use assets and represent the net difference between operating lease liabilities and right-of-use assets.

The New Leasing Standard requires us to classify certain reagent rental programs as sales-type leases and thus accelerate instrument revenue and cost recognition at the time of instrument placement. We did not change the historical lease classification for placements prior to January 1, 2019, therefore this change will apply to certain new placements beginning on January 1, 2019. Under prior U.S. GAAP, instruments placed under our reagent rental programs were classified as operating leases and instrument revenue and cost was recognized over the term of the program. The New Leasing Standard did not have a material impact on our consolidated earnings and had no impact on cash flows for the three and six months ended June 30, 2019.

Adoption of the New Leasing Standard impacted our condensed consolidated balance sheet as follows:

TOTAL LIABILITIES	$	1,546,582	$	1,629,297	$	82,715

We adopted ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, on January 1, 2019. We elected not to reclassify the $1.7 million of stranded tax effects from the Tax Cuts and Jobs Act enacted on December 22, 2017, from accumulated other comprehensive income to retained earnings in the period of adoption.

In August 2018, the SEC issued Final Rule Release No. 33-10532, “Disclosure Update and Simplification,” which makes a number of changes meant to simplify interim disclosures. The new rule requires a presentation of changes in stockholders’ equity and noncontrolling interest in the form of a reconciliation, either as a separate financial statement or in the notes to the financial statements, for the current and comparative year-to-date interim periods. The additional elements of this release did not have a material impact on our overall condensed consolidated financial statements. We adopted the new disclosure requirements in our Form 10-Q during the first quarter of 2019.

New Accounting Pronouncements Not Yet Adopted

For a discussion of other accounting standards that have been issued by the FASB prior to January 1, 2019, but are not yet effective, refer to Note 2. Summary of Significant Accounting Policies - New Accounting Pronouncements Not Yet Adopted in our 2018 Annual Report.

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 applied 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 that can include various 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, contract assets and lease receivables as a result of revenue recognized in advance of

billings (included within other assets), 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. 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. 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.

Reference Laboratory Diagnostic and Consulting Services. Reference laboratory 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 agreements to purchase specified amounts of consumables, which are considered embedded leases. 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 $4.6 million and $9.2 million for the three and six months ended June 30, 2019, respectively, as compared to $3.1 million and $6.0 million for the three and six months ended June 30, 2018, respectively, including both operating leases and sales-type leases under ASC 842, Leases, during 2019, and ASC 840, Leases, prior to 2019. See 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 1 to 5 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, 2018, our deferred revenue related to extended warranties and post-contract support was $40.7 million, of which approximately $3.0 million and $15.7 million were recognized during the three and six months ended June 30, 2019, respectively. Furthermore, as a result of new agreements, our deferred revenue related to extended warranties and post-contract support was $38.9 million at June 30, 2019. 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 $25.6 million at June 30, 2019, of which approximately 18%, 33%, 25% and 24% are expected to be recognized during the remainder of 2019, the full year 2020, the full year 2021, 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 IDEXX Neo^®, Animana^®, 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 2 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 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 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 performance obligation 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 which 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 its 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 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. We have determined these agreements do not include a significant financing component. Differences between estimated and actual customer purchases may impact the amount and timing of revenue recognition.

On December 31, 2018, our capitalized customer acquisition costs were $124.4 million, of which approximately $8.8 million and $17.7 million were recognized as a reduction of revenue during the three and six months ended June 30, 2019, respectively. Furthermore, as a result of new up-front customer loyalty payments, our capitalized customer acquisition costs were $126.4 million at June 30, 2019. 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, revenue adjustments that relate to performance obligations satisfied in prior periods, and contract modifications during the three and six months ended June 30, 2019, were not material.

Volume Commitment Programs. Our volume commitment programs, such as our IDEXX 360 program, provide customers with a free or discounted instrument or system 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 in advance of billing the customer at the time of installation and customer acceptance, 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 amount and timing of revenue recognition.

On December 31, 2018, our volume commitment contract assets were $40.9 million, of which approximately $2.3 million and $5.0 million were reclassified to accounts receivable when customers were billed for related products and services during the three and six months ended June 30, 2019, respectively. Furthermore, as a result of new placements under volume commitment programs, our contract assets were $60.4 million at June 30, 2019. 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, revenue adjustments that relate to performance obligations satisfied in prior periods, and contract modifications during the three and six months ended June 30, 2019, 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 $1.5 billion, of which approximately 13%, 24%, 20%, and 43% are expected to be recognized during the remainder of 2019, the full year 2020, the full year 2021, and thereafter, respectively. These future revenues relate to performance obligations not yet satisfied, for which customers have committed to purchase goods and services, 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, previously referred to as IDEXX Instrument Marketing 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 recognized upon the purchase of future products and services, offsetting future rebates as they are earned.

On December 31, 2018, our deferred revenue related to instrument rebate programs was $57.4 million, of which approximately $4.6 million and $9.5 million were recognized when customers purchased eligible products and services and earned rebates during the three and six months ended June 30, 2019, respectively. Furthermore, as a result of new instrument purchases under rebate programs, our deferred revenue was $52.6 million at June 30, 2019, of which approximately 17%, 29%, 23%, and 31% are expected to be recognized during the remainder of 2019, the full year 2020, the full year 2021, 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, as defined within the New Leasing Standard. We elected the package of practical expedients permitted under the transition guidance within the New Leasing Standard, which among other things, allowed us to carryforward our historical lease classification and therefore all reagent rental program placements prior to January 1, 2019 will continue to be classified as operating leases. We have not elected the practical expedient within the New Leasing Standard to combine lease and non-lease components.

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. As a result of new placements under reagent rental programs, our lease receivable assets were $2.6 million at June 30, 2019. The impact of discounting and unearned income at June 30, 2019 were not material. Profit and loss recognized at the commencement date and interest income

during the three and six months ended June 30, 2019 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, 2019 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, 2019, we transferred instruments of $3.0 million and $5.0 million, respectively, as compared to $4.1 million and $8.1 million for the three and six months ended June 30, 2018, respectively, from inventory to property and equipment.

We estimate future revenue to be recognized related to our reagent rental programs of approximately $33.6 million, of which approximately 21%, 34%, 25%, and 20% are expected to be recognized during the remainder of 2019, the full year 2020, the full year 2021, 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 during the three and six months ended June 30, 2019, 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.

Future market conditions and changes in product offerings may cause us to change marketing strategies to increase or decrease customer incentive offerings, possibly resulting in incremental reductions of revenue in future periods as compared to reductions in the current or prior periods. Additionally, certain customer programs require us to estimate, based on historical experience, and apply judgment to predict the amounts of future customer purchases, customer rebates and other incentive payments, and price adjustments related to multi-year agreements. Differences between estimated and actual customer purchases may impact the amount and timing of revenue recognition.

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. We maintain allowances for doubtful accounts 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. 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. Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered. We do not have any off-balance sheet credit exposure related to our customers. We have no significant customers that accounted for greater than 10% of our consolidated revenues and we have no concentration of credit risk as of June 30, 2019.

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 thresholds to be reported as a separate segment, we believe it is important to disaggregate these revenues as a major product and service category within 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:໿

Total	$	620,103	$	580,752	$	1,196,159	$	1,118,408

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, 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, 2018, our deferred commission costs, included within other assets, were $13.9 million, of which approximately $1.1 million and $2.3 million of commission expense were recognized during the three and six months ended June 30, 2019, respectively. Furthermore, as a result of commissions related to new extended warranties and SaaS subscriptions, our deferred commission costs were $14.8 million at June 30, 2019. Impairments of deferred commission costs during the three and six months ended June 30, 2019, were not material.

NOTE 4. ACQUISTIONS

We believe that our acquisitions of businesses and other assets enhance our existing businesses by either expanding our geographic range and customer base or expanding our existing product lines. During the second quarter of 2019, we completed an acquisition which was immaterial to our consolidated financial statements for the three and six months ended June 30, 2019.

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, 2019, totaled $1.9 million and $36.3 million, respectively, as compared to $1.7 million and $32.8 million for the three and six months ended June 30, 2018, respectively. The total unrecognized compensation expense, net of estimated forfeitures, for unvested share-based compensation awards outstanding at June 30, 2019, was $68.7 million, which will be recognized over a weighted average period of approximately 2.1 years. During the three and six months ended June 30, 2019, we recognized expenses of $6.9 million and $13.2 million, respectively, as compared to $6.5 million and $12.4 million for the three and six months ended June 30, 2018, 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 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,
	2019			2018

Share price at grant	$	208.25		$	179.56
Expected stock price volatility	26		%	24		%
Expected term, in years	6.0			5.8
Risk-free interest rate	2.5		%	2.7		%
Weighted average fair value of options granted	$	63.93		$	52.99

NOTE 6. 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. The components of inventories were as follows:



(in thousands)	June 30, 2019		December 31, 2018

Raw materials	$	38,010	$	31,973
Work-in-process	19,398		17,009
Finished goods	139,468		124,321
Inventories	$	196,876	$	173,303

NOTE 7. LEASES

The majority of our facilities are occupied under operating lease arrangements with various expiration dates through 2067, some of which include options to extend the life of the lease, and some of which include options to terminate the lease within 1 year. In certain instances, we are responsible for the real estate taxes and operating expenses related to these facilities. Additionally, we enter into operating leases for certain vehicles and office equipment in the normal course of business. We determine the expected term of any executed agreements using the non-cancelable lease term plus any renewal

options by which the failure to renew imposes a penalty in such amount that renewal is reasonably assured. The derived expected term is then used in the determination of a financing or operating lease and in the calculation of straight-line rent expense. Rent escalations are considered in the calculation of minimum lease payments in our capital lease tests and in determining straight-line rent expense for operating leases. Minimum lease payments include the fixed lease component of the agreement, as well as fixed rate increases that are initially measured at the lease commencement date. Variable lease payments based on an index, payments associated with non-lease components and short-term rentals (leases with terms less than 12 months) are expensed as incurred. Consideration is allocated to the lease and non-lease components based on the estimated standalone prices.

We determine if an arrangement is a lease at its inception. Operating leases are included in operating lease right-of-use assets, accrued liabilities, and long-term operating lease liabilities in our consolidated balance sheets. Our financing leases are not material to our financial statements.

Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease liabilities and right-of-use assets are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an explicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Rent expense for lease payments is recognized on a straight-line basis over the lease term. The operating lease right-of-use assets also includes any rent prepayments, lease incentives upon receipt and straight-line rent expense impacts, which represent the difference between our operating lease liabilities and right-of-use assets.

Maturities of operating lease liabilities were as follows:



(in thousands, except lease term and discount rate)	June 30, 2019

2019 (remainder of year)	$	8,378
2020	18,661

Long-term operating lease liabilities	$	69,331

Weighted average remaining lease term - operating leases	10.7 years

Weighted average discount rate - operating leases	3.5		%

Rent expense charged to operations under operating leases was approximately $5.1 million and $10.3 million during the three and six months ended June 30, 2019, respectively. Variable rent and short-term lease expenses were not material.

Supplemental cash flow information for leases was as follows:

Cash paid for amounts included in the measurement of operating leases liabilities	$	10,010
Right-of-use assets obtained in exchange for operating lease obligations, net of early lease terminations	$	5,560

At December 31, 2018, under ASC 840 Leases, the minimum annual rental payments under our lease agreements were as follows: $19.4 million in 2019; $17.1 million in 2020; $14.5 million in 2021; $10.8 million in 2022; $8.5 million in 2023; and $36.5 million thereafter.

NOTE 10. DEBT

On December 19, 2014, we entered into a Multicurrency Note Purchase and Private Shelf Agreement among ourselves, Metropolitan Life Insurance Company ("MetLife"), and each of the accredited institutional purchasers named therein

(the "Existing Agreement"). Pursuant to the terms of the Existing Agreement, we may request that MetLife purchase, over the three-year period beginning on December 19, 2014, up to $50 million of additional senior promissory notes of ours at a fixed interest rate and with a maturity date not to exceed fifteen years (the "Shelf Notes").

On March 14, 2019, we amended the Existing Agreement to (i) increase the Shelf Notes facility size from $50 million to $150 million, (ii) extend the Shelf Notes facility issuance period from December 19, 2017 to December 20, 2021 and (iii) make various implementing and administrative changes in order to facilitate a $100 million Shelf Notes issuance on March 14, 2019. We also submitted to MetLife a request to purchase $100 million of our Shelf Notes at a 4.19% per annum rate, due March 14, 2029, (the "Series C Notes"). We used the proceeds received from the Series C Notes for general corporate purposes, including a partial repayment of borrowings under our Credit Facility.

NOTE 11. 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, 2019 and 2018, 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:

NOTE 12. INCOME TAXES

Our effective income tax rate was 19.5% for the three months ended June 30, 2019, as compared to 20.9% for the three months ended June 30, 2018, and 18.7% for the six months ended June 30, 2019, as compared to 18.0% for the six months ended June 30, 2018. The decrease in our effective tax rate for the three months ended June 30, 2019, as compared to the same period in the prior year, was primarily driven by statutory earnings mix, with relatively higher statutory earnings subject to lower international tax rates than domestic tax rates. The increase in our effective tax rate for the six months ended June 30, 2019, as compared to the same period in the prior year, was primarily driven by lower tax benefits from share-based compensation, partially offset by a nonrecurring item recorded in the three months ended March 31, 2018, that resulted from the 2017 Tax Cut and Jobs Act, as well as statutory earnings mix, with relatively higher statutory earnings subject to lower international tax rates than domestic tax rates.

The effective tax rate for the three and six months ended June 30, 2019, differed from the U.S. statutory tax rate of 21% primarily due to tax benefits from share-based compensation.

NOTE 14. 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. See Note 5 to the consolidated financial statements in our 2018 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,
	2019	2018	2019	2018

Shares outstanding for basic earnings per share	86,215	87,004	86,210	87,166

NOTE 15. COMMITMENTS, CONTINGENCIES AND GUARANTEES

Commitments

See "Note 7. Leases", for more information regarding our lease commitments.

Contingencies and Guarantees

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. At June 30, 2019, our accruals with respect to actual and threatened litigation were not material.

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.

We have had no significant changes to our contingencies and guarantees discussed in Note 15 to the consolidated financial statements in our 2018 Annual Report.

NOTE 16. SEGMENT REPORTING

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 Interim Chief Executive Officer. Our reportable segments include diagnostic and information technology-based products and services for the veterinary market, which we refer to as the Companion Animal Group (“CAG”), water quality products (“Water”) and diagnostic products and services for livestock and poultry health and to ensure the quality and safety of milk and improve dairy efficiency, which we refer to as Livestock, Poultry and Dairy (“LPD”). Our Other operating segment combines and presents products for the human point-of-care medical diagnostics market with our out-licensing arrangements. Assets are not allocated to segments for internal reporting purposes.

Certain costs are not allocated to our operating segments and are instead reported under the caption “Unallocated Amounts.” These costs include costs that do not align with one of our existing operating segments or are cost prohibitive to allocate, which primarily consist of our R&D function, regional or country expenses, certain foreign currency revaluation and settlement gains and losses on monetary balances in currencies other than our subsidiaries’ functional currency and unusual items. Corporate support function costs (such as information technology, facilities, human resources, finance and legal), health benefits and incentive compensation are charged to our business segments at pre-determined budgeted amounts or rates. Differences from these pre-determined budgeted amounts or rates are also captured within Unallocated Amounts.

The following is a summary of segment performance:

NOTE 17. 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, 2019.

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.

The amounts outstanding under our unsecured revolving credit facility (“Credit Facility” or “line of credit”) 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 $748.1 million and $701.1 million, respectively, as of June 30, 2019, and $607.3 million and $601.8 million, respectively, as of December 31, 2018.

The following tables set forth our assets and liabilities that were measured at fair value on a recurring basis by level within the fair value hierarchy:

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


(3)	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.


(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 (2) above.

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

NOTE 18. 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. The primary risk that we currently manage by using hedging instruments is foreign currency exchange risk. We may also enter into interest rate swaps to minimize the impact of interest rate fluctuations associated with borrowings under our variable-rate Credit Facility.

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 the designation of such instruments as hedging transactions.

We recognize all hedging instruments on the balance sheet at fair value at the balance sheet date. Instruments that do not qualify for hedge accounting treatment must be 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. See “Note 13. 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, 2019 and 2018.

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 as cash flow hedges as these derivative instruments mitigate the exposure to variability in the cash flows of forecasted transactions attributable to foreign currency exchange. 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, 2019 or 2018. At June 30, 2019, the estimated amount of net gains, net of income tax, which are expected to be reclassified out of AOCI and into earnings within the next 12 months, is $4.0 million if exchange rates do not fluctuate from the levels at June 30, 2019.

We hedge approximately 85% of the estimated exposure from intercompany product purchases and sales denominated in the euro, British pound, Canadian dollar, Japanese yen, Australian dollar, and Swiss franc. 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 $225.6 million and $190.9 million at June 30, 2019 and December 31, 2018, respectively.

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

Net Investment Hedges

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 a loss of $1.0 million and a gain of $0.5 million, net of tax, within AOCI as a result of this net investment hedge for the three and six months ended June 30, 2019, respectively. The related cumulative unrealized gain recorded at June 30, 2019, will not be reclassified in earnings until the complete or substantially complete liquidation of the net investment in the hedged foreign operations or a portion of the hedge no longer qualifies for hedge accounting treatment. See Note 12 to the consolidated financial statements included in our 2018 Annual Report for further information regarding the issuance of these euro-denominated notes.

During May 2018, January 2019, and March 2019, we entered into 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. The cross currency swaps have a maturity date of June 30, 2023. At maturity of the cross currency swap contracts, we will deliver the notional amount of €80.0 million and will receive approximately $93.5 million from the counterparties. The change 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, 2019, we recorded a loss of $0.5 million and a gain of $0.9 million, net of tax, within AOCI as a result of these net investment hedges, 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, thus is recognized as a reduction to interest expense over the life of the hedge instrument. We recognized approximately $0.6 million and $1.1 million related to the excluded component as a reduction of interest expense for the three and six months ended June 30, 2019, respectively.

Business Overview

We develop, manufacture, and distribute products and provide services primarily for the companion animal veterinary, livestock, poultry and dairy, and water testing markets. We also sell a line of portable electrolytes and blood gas analyzers for the human point-of-care medical diagnostics market. 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 veterinaries;


•	Health monitoring, biological materials testing, 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;


•	Point-of-care electrolytes and blood gas analyzers used in the human point-of-care medical diagnostics market.

Operating Segments. We operate primarily through three business segments: diagnostic and information technology-based products and services for the veterinary market, which we refer to as the Companion Animal Group (“CAG”), water quality products (“Water”) and diagnostic products and services for livestock and poultry health and to ensure the quality and safety of milk and improve dairy reproductive efficiency, which we refer to as Livestock, Poultry and Dairy (“LPD”). Our Other operating segment combines and presents products for the human point-of-care medical diagnostics market (“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 performs services for veterinarians and the biomedical analytics market, 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 and food. OPTI Medical manufactures and distributes point-of-care electrolyte and blood gas analyzers and related consumable products for the human medical diagnostics market.

Executive Officers. Effective June 28, 2019, the Board of Directors appointed Jay Mazelsky as Interim President and Chief Executive Officer, following a serious bicycling accident on June 27, 2019 involving Jonathan W. Ayers, Chairman, President and Chief Executive Officer, which resulted in Mr. Ayers sustaining a severe spinal cord injury. Mr. Mazelsky has assumed Mr. Ayers’s management responsibilities while continuing to oversee our North American Companion Animal Group Commercial Organization and key elements of our innovation portfolio, including our global in-house diagnostics and Veterinary Software and Services businesses. Mr. Mazelsky is working closely with Brian McKeon, our Chief Financial Officer, who has assumed additional oversight responsibility for the Water and Livestock, Poultry and Dairy business segments, as well as the Companion Animal Group business in Latin America and the business of OPTI Medical Systems, Inc., while continuing to be responsible for our finance, corporate development and strategy, worldwide operations and investor relations functions. Larry Kingsley, independent Lead Director of the Board, is providing additional support to Mr. Mazelsky, Mr. McKeon and the management team. Mr. Ayers remains as Chairman of the Board. While we cannot provide assurances as to whether we may experience management or other challenges in connection with the leadership transition that could adversely affect our future success, we believe that under the leadership of Mr. Mazelsky, Mr. McKeon and the other members of management, with additional support by Mr. Kingsley, we will continue to successfully execute our strategy and create value for shareholders.

Directors. On July 16, 2019, the Board of Directors elected Sam Samad, the Senior Vice President and Chief Financial Officer of Illumina, Inc., as an independent director and member of its Audit Committee effective that date.

Effects of Certain Factors and Trends on Results of Operations

Currency Impact. See “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. See “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 2018 Annual Report for additional information regarding 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, 2019, are consistent with those discussed in our 2018 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 of recent accounting standards and amendments will have on our consolidated financial statements as described in Note 2 to the unaudited condensed consolidated financial statements in Part I, Item 1 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, 2019, as compared to the same period 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, revenues reported in accordance with U.S. GAAP, and may not be comparable to similarly titled measures reported by other companies. Management believes that reporting organic revenue growth provides useful information to investors by facilitating easier comparisons of our revenue performance with prior and future periods and to 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 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 exclude only acquisitions that are considered to be a business from organic revenue growth. In a business combination, if substantially all the fair value of the assets acquired is concentrated in a single asset or group of similar assets, we do not consider these assets to be a business and include these acquisitions in organic revenue growth. 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.

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.

Comparison to Prior Periods

Our fiscal quarter(s) 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.

Total Company Revenue. The increase in both U.S. and international organic revenues was driven by strong volume gains in CAG Diagnostics recurring revenue, supported by our differentiated diagnostic technologies and expanded commercial organization that are driving increased volumes from new and existing customers in our reference laboratory business and high growth in consumable revenue, supported by the impact of the continued expansion of our CAG Diagnostics instrument installed base globally. Our Water business also contributed to our overall growth, primarily from higher sales volumes of our Colilert^® test products and related accessories. The impact of currency movements decreased revenue by 2.1%.

The following table presents total Company results of operations:

Income from operations	$	164,275	26.5	%	$	145,594	25.1	%	$	18,681		12.8	%

Gross Profit. Gross profit increased due to higher sales volumes and a 50 basis point increase in the gross profit percentage. The increase in the gross profit percentage was driven by several factors, including the net benefit of price increases in our CAG Diagnostics recurring revenue portfolio, mix benefits from lower relative IDEXX VetLab instrument revenue and high growth in IDEXX VetLab consumable revenues, volume leverage, and the favorable impact of lower product costs in our CAG business. The impact from foreign currency movements increased gross profit margin by approximately 20 basis points, including the impact of hedge gains in the current year, as compared to hedge losses in the prior year.

Operating Expenses. The changes in currency exchange rates, including foreign exchange losses on settlements of foreign currency denominated transactions recorded within Unallocated Amounts, resulting in approximately a 2% decrease to our overall operating expenses. Sales and marketing expense increased approximately 7%, excluding the impact of foreign currency, primarily due to increased personnel-related costs from our expanded global commercial infrastructure. General and administrative expense increased approximately 2%, excluding the impact of foreign currency, primarily due to personnel related costs, partially offset from the benefits of cost control initiatives across our business segments. Research and development expense increased primarily due to higher project and personnel-related costs, with an immaterial impact from foreign currency.

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

CAG Diagnostics Recurring Revenue. The increase in CAG Diagnostics recurring revenue was primarily due to increased volumes in IDEXX VetLab consumables and reference laboratory diagnostic services, and to a lesser extent, higher realized prices.

IDEXX VetLab consumables revenue growth was primarily due to higher sales volumes across all regions for our Catalyst^® consumables, including IDEXX SDMA^® consumables, and to a lesser extent, Procyte Dx^® consumables. These increases were supported by an expansion of our instrument installed base, growth in testing by new and existing customers, our expanded menu of available tests, and to a lesser extent, benefits from higher average unit sales prices. Current quarter growth reflected the impact of increased customer stocking in the U.K. during the first quarter of 2019, in anticipation of the planned exit from the European Union.

The increase in rapid assay revenue resulted primarily from higher sales volumes of canine SNAP^® 4Dx^® Plus and to a lesser extent, higher realized prices.

The increase in reference laboratory diagnostic and consulting services revenue was primarily due to the impact of higher testing volumes throughout our worldwide network of laboratories, most prominently in the U.S., resulting from increased testing from new and existing customers, supported by our differentiated diagnostic technologies, such as IDEXX SDMAand fecal antigen testing. The increase was also the result of higher average unit sales prices.

CAG Diagnostics services and accessories revenue growth was primarily a result of the increase in our active installed base of instruments.

CAG Diagnostics Capital – Instruments Revenue. The decrease in instrument revenue reflects slightly lower overall instrument placements as well as the impact of product mix, including lower SediVue Dx^® analyzer placements compared to high prior year levels, partially offset by higher Procyte Dx analyzer placements.

Veterinary Software, Services and Diagnostic Imaging Systems Revenue. The increase in revenue was primarily due to increased veterinary software, subscription, and services, as well as higher realized prices on these service offerings, and to a lesser extent, higher diagnostic imaging services as a result of the increase in our active installed base. These increases were partially offset by lower allocated revenue per unit on our diagnostic imaging systems related to increased placements under our customer volume commitment programs. Our acquisition of a software company in the second half of 2018 contributed 1.8% to reported revenue growth.

The following table presents the CAG segment results of operations:

Income from operations	$	144,583	26.4	%	$	129,796	25.6	%	$	14,787	11.4	%

Gross Profit. Gross profit increased primarily due to higher sales volume as well as a 60 basis point increase in the gross profit percentage. The increase in gross profit percentage was driven by the mix benefits from lower relative IDEXX VetLab instrument revenue and high growth in IDEXX VetLab consumable revenues, lower product costs, as well as the net benefit of price increases in our CAG Diagnostics recurring revenue portfolio, partially offset by incremental net investments in lab capacity and software services field resources. The impact from foreign currency movements increased gross profit margin by approximately 10 basis points, including the impact of hedge gains in the current year, as compared to hedge losses in the prior year.

Operating Expenses. The increase in sales and marketing expense was primarily due to increased personnel-related costs related to our expanded global commercial infrastructure. The increase in general and administrative expense was the result of higher personnel-related costs. The increase in research and development expense was primarily due to increased personnel-related costs and higher project costs. The overall change in currency exchange rates decreased operating expenses by approximately 1%.

Water

Income from operations	$	16,567	47.7	%	$	15,122	46.3	%	$	1,445		9.6	%

Revenue. The increase in revenue was primarily attributable to higher sales volumes and the benefit of price increases of our Colilert test products and related accessories used in coliform and E. coli testing, including strong volume growth rates in most regions, including the U.S. The impact of currency movements decreased revenue by approximately 3.2%.

Gross Profit. Gross profit increased due to higher sales volumes as well as a 90 basis point increase in the gross profit percentage. The impact from foreign currency movements increased our gross profit percentage by approximately 70 basis points, including the impact of hedge gains in the current year, as compared to hedge losses in the prior year. The remaining increase in the gross profit percentage was primarily due to the net benefit of price increases and product mix, partially offset by higher product and distribution costs.

Operating Expenses. The decrease in sales and marketing expense and increase in research and development expense were primarily due to the realignment of certain personnel within operating expense categories. General and administrative expense increased primarily due to increased personnel-related costs. The overall change in currency exchange rates resulted in a decrease in operating expenses of approximately 3%.

Livestock, Poultry and Dairy

Income from operations	$	6,393	19.3	%	$	6,471	18.5	%	$	(78	)	(1.2	%)

Revenue. The decrease in revenue was primarily due to the unfavorable impact of foreign currency movements that decreased revenue by approximately 5.0%, as well as a decline in diagnostic testing related to African swine fever outbreaks in China and lower bovine testing across most regions, most prominently in Europe. These decreases were partially offset by increased herd health screening, higher poultry testing volumes, primarily in Latin America, and higher pregnancy testing in our European and Asia Pacific regions.

Gross Profit. The decrease in gross profit was primarily due to lower sales volume, partially offset by a 40 basis point increase in the gross profit percentage driven by the impact from foreign currency movements. Foreign currency movements increased gross profit margin by approximately 110 basis points, including the impact of hedge gains in the current year, as compared to hedge losses in the prior year. Excluding the impact of foreign currency movements, the decrease in gross profit percentage was primarily due to higher herd health screening costs, partially offset by the net benefit of price increases and favorable product mix.

Operating Expenses. The decrease in sales and marketing expense was primarily due to lower personnel-related costs, including cost control initiatives. The decrease in general and administrative expense was primarily due to lower third-party services and travel costs. The increase in research and development expense was primarily due to increased personnel-related costs. The overall change in currency exchange rates resulted in a decrease in operating expenses of approximately 2%.

Income from operations	$	752	15.4	%	$	1,130	20.1	%	$	(378	)	(33.5	%)

Revenue. The decrease in revenue was due to lower royalties associated with intellectual property related to our former pharmaceutical product line, lower volumes of our OPTI Medical analyzers and related consumables, as well as lower realized prices on our OPTI Medical products and services. The impact of currency movements on revenue was immaterial.

Gross Profit. The decrease in gross profit was due to a 5.1% decrease in the gross profit percentage primarily due to unfavorable product mix from lower royalties, as well as lower price realization and higher service costs on OPTI Medical products and services, partially offset by lower distribution expense. The overall change in currency exchange rates had an immaterial impact on the gross profit percentage.

Operating Expenses. The decrease in sales and marketing expense was primarily due to lower personnel-related costs. The decrease in general and administrative expense was primarily due to the recovery of previously established bad debt reserves in the Middle East. The increase in research and development cost was primarily due to higher personnel-related and project costs.

Unallocated Amounts

We estimate certain personnel-related costs and allocate these budgeted expenses to the operating segments. This allocation differs from actual expense and consequently yields a difference that is reported under the caption “Unallocated Amounts.”

The following table presents the Unallocated Amounts results of operations:

Loss from operations	$	(4,020	)	$	(6,925	)	$	2,905		(41.9	%)

Unallocated Amounts. The change in unallocated amounts was due to lower foreign exchange losses on settlements of foreign currency denominated transactions, lower unallocated employee benefit costs, and lower unallocated corporate function costs due to cost control initiatives.

Non-Operating Items

Interest Expense. Interest expense was $8.2 million for the three months ended June 30, 2019, as compared to $8.5 million for the same period in the prior year. The decrease in interest expense was the result of lower average debt levels, offset by higher interest rates. We also realized lower interest expense from the benefit of our cross currency swaps, as well as increased capitalized interest related to the expansion of our Westbrook, Maine headquarters and relocation of our core reference laboratory in Germany.

Provision for Income Taxes. Our effective income tax rate was 19.5% for the three months ended June 30, 2019, as compared to 20.9% for the three months ended June 30, 2018. The decrease in our effective tax rate was primarily driven by statutory earnings mix, with relatively higher statutory earnings subject to lower international tax rates than domestic tax rates.

Total Company Revenue. The increase in both U.S. and international organic revenues was driven by strong volume gains in CAG Diagnostics recurring revenue, supported by our differentiated diagnostic technologies and expanded commercial organization that are driving increased volumes from new and existing customers in our reference laboratory business and high growth in consumable revenues, supported by the impact of the continued expansion of our CAG Diagnostics instrument installed base globally. Our Water business also contributed to our overall growth, primarily from higher sales volumes of our Colilert test products and related accessories. The impact of currency movements decreased revenue by 2.4%.

The following table presents total Company results of operations:

Income from operations	$	297,413	24.9	%	$	258,638	23.1	%	$	38,775		15.0	%

Gross Profit. Gross profit increased due to higher sales volumes and an 80 basis point increase in the gross profit percentage. The increase in the gross profit percentage was driven by several factors, including the net benefit of price increases in our CAG Diagnostics recurring revenue portfolio, mix benefits from lower relative IDEXX VetLab instrument revenue and high growth in IDEXX VetLab consumable revenues, volume leverage, and the favorable impact of lower product costs in our CAG business. The impact from foreign currency movements increased gross profit by approximately 15 basis points, including the impact of hedge gains in the current year, as compared to hedge losses in the prior year.

Operating Expenses. The overall change in currency exchange rates resulted in a decrease in operating expenses of approximately 2%, including lower foreign exchange losses on settlements of foreign currency denominated transactions recorded within Unallocated Amounts. Sales and marketing expense increased approximately 8%, excluding the impact of foreign currency, primarily due to increased personnel-related costs related to our expanded global commercial infrastructure. General and administrative expense increased approximately 2%, excluding the impact of foreign currency, primarily due to personnel related costs, partially offset from the benefits of cost control initiatives across our business segments. Research and development expense increased primarily due to higher personnel-related costs, with an immaterial impact from foreign currency.

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

IDEXX VetLab consumables revenue growth was primarily due to higher sales volumes across all regions for our Catalyst consumables, including IDEXX SDMA consumables, and to a lesser extent, Procyte Dx consumables. These increases were supported by an expansion of our instrument installed base, growth in testing by new and existing customers, our expanded menu of available tests, and to a lesser extent, benefits from higher average unit sales prices.

The increase in rapid assay revenue resulted from higher sales volumes and average unit prices of canine SNAP^® 4Dx Plus tests and to a lesser extent, higher realized prices.

CAG Diagnostics services and accessories revenue growth was primarily a result of the increase in our active installed base of instruments.

CAG Diagnostics Capital – Instruments Revenue. The decrease in instrument revenue reflects slightly lower overall instrument placements as well as the impact of product mix, including lower SediVue Dx analyzer placements compared to high prior year levels, partially offset by higher Procyte Dx analyzer placements.

our volume commitment programs. Our acquisition of a software company in the second half of 2018 contributed approximately 2.0% to reported revenue growth.

Income from operations	$	259,605	24.6	%	$	230,194	23.5	%	$	29,411	12.8	%

Gross Profit. Gross profit increased primarily due to higher sales volume as well as a 70 basis point increase in the gross profit percentage. The increase in gross profit percentage was driven by mix benefits from lower relative IDEXX VetLab instrument revenue and high growth in IDEXX VetLab consumable revenues, lower product costs, as well as the net benefit of price increases in our CAG Diagnostics recurring revenue portfolio. The impact from foreign currency movements increased gross profit margin by approximately 10 basis points, including the impact of hedge gains in the current year, as compared to hedge losses in the prior year.

Operating Expenses. The increase in sales and marketing expense was primarily due to increased personnel-related costs as we continue to invest in our global commercial infrastructure. The increase in general and administrative expense resulted primarily from higher personnel-related costs. The increase in research and development expense was primarily due to increased personnel-related costs and higher project costs. The overall change in currency exchange rates resulted in an decrease in operating expenses by approximately 2%.

Income from operations	$	30,349	46.6	%	$	27,584	44.6	%	$	2,765		10.0	%

Revenue. The increase in revenue was attributable to the benefit of price increases and higher sales volumes of our Colilert test products and related accessories used in coliform and E. coli testing, including strong volume growth across all regions. The impact of currency movements decreased revenue by approximately 3.6%.

Gross Profit. Gross profit increased due to higher sales volumes as well as a 190 basis point increase in the gross profit percentage. The impact from foreign currency movements increased our gross profit percentage by approximately 75 basis points, including the impact of hedge gains in the current year, as compared to hedge losses in the prior year. The remaining increase in the gross profit percentage was primarily due to the net benefit of price increases and product mix, partially offset by higher product and distribution costs.

Operating Expenses. The decrease in sales and marketing expense and increase in research and development expense were primarily due to the realignment of certain personnel within operating expense categories. General and administrative expense increased primarily due to personnel-related costs. The overall change in currency exchange rates resulted in a decrease in operating expenses of approximately 3%.

Livestock, Poultry and Dairy

Income from operations	$	12,643	19.6	%	$	9,432	14.0	%	$	3,211		34.0	%

Revenue. The decrease in revenue was primarily due to the unfavorable impact of foreign currency movements that decreased revenue by approximately 5.6%, lower bovine testing across most regions, primarily in Europe, and a decline in diagnostic testing related to African swine fever outbreaks in China. These decreases were partially offset by increased herd health screening and higher poultry testing volumes across our Asia Pacific and European regions, and higher pregnancy testing in our European and Asia Pacific regions.

Gross Profit. The increase in gross profit was primarily due to higher herd health screening volumes as well as a 300 basis point increase in the gross profit percentage. The impact from foreign currency movements increased gross profit margin by approximately 120 basis points, including the impact of hedges. The remaining increase in the gross profit percentage reflected favorable product mix as well as lower product costs, partially offset by higher herd health screening costs.

Operating Expenses. The decrease in sales and marketing expense was primarily due to lower personnel-related costs, including cost control initiatives. The decrease in general and administrative expense was primarily due to lower third-party services and personnel-related costs. The increase in research and development expense was primarily due to increased personnel-related costs. The overall change in currency exchange rates resulted in a decrease in operating expenses of approximately 3%.

Revenue. The decrease in revenue was due to lower volumes of our OPTI Medical analyzers and related consumables, as well as lower realized prices on our OPTI Medical products and services. The impact of currency movements on revenue was immaterial.

Gross Profit. The increase in gross profit was due to a 4.2% increase in the gross profit percentage primarily due to the benefit of product mix within our OPTI Medical product line, higher OPTI Medical realized prices and, to a lesser extent, lower OPTI Medical product costs. These increases were partially offset by higher OPTI Medical service costs. The overall change in currency exchange rates had an immaterial impact on the gross profit percentage.

Operating Expenses. The decrease in sales and marketing was primarily due to lower personnel costs. The decrease in general and administrative cost was primarily due to the recovery of previously established bad debt reserves in Africa and the Middle East. The increase in research and development cost was primarily due to higher personnel-related and project costs.

Unallocated Amounts. The change in unallocated amounts was due to lower unallocated corporate function costs, including cost control initiatives, lower unallocated employee benefit costs, and lower foreign exchange losses on settlements of foreign currency denominated transactions.

Non-Operating Items

Interest Income. Interest income was $0.1 million for the six months ended June 30, 2019, as compared to $0.8 million for the six months ended June 30, 2018. The decrease in interest income was primarily due to the liquidation of our portfolio of marketable securities during the first quarter of 2018.

Interest Expense. Interest expense was $16.6 million for the six months ended June 30, 2019, as compared to $17.7 million for the same period in the prior year. The decrease in interest expense was the result of lower average debt levels, offset by higher interest rates. We also realized lower interest expense from the benefit of our cross currency swaps, as well as increased capitalized interest related to the expansion of our Westbrook, Maine headquarters and relocation of our core reference laboratory in Germany.

Provision for Income Taxes. Our effective income tax rate was 18.7% for the six months ended June 30, 2019, as compared to 18.0% for the six months ended June 30, 2018. The increase in the effective tax rate was primarily driven by lower tax benefits from share-based compensation, partially offset by a nonrecurring item recorded in the three months ended March 31, 2018, that resulted from the 2017 Tax Cut and Jobs Act and statutory earnings mix, with relatively higher statutory earnings subject to lower international tax rates than domestic tax rates.

Liquidity and Capital Resources

Liquidity

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. At June 30, 2019, we had $110.8 million of cash and cash equivalents, as compared to $123.8 million on December 31, 2018. Working capital, including our Credit Facility, totaled $93.4 million at June 30, 2019, as compared to negative $116.3 million at December 31, 2018. Additionally, at June 30, 2019, we had remaining borrowing availability of $597.2 million under our $850 million Credit Facility. We believe that, if necessary, we could obtain additional borrowings at similar rates to our existing 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 on favorable terms 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 in the U.S. than is generated by our operations, for example to fund significant discretionary activities, we could elect to raise capital in the U.S. through debt or equity issuances. 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 and marketable securities are generally available without restrictions to fund ordinary business operations outside the U.S.

Accounts receivable	$	(37,699	)	$	(32,872	)	$	(4,827	)

Total change in cash due to changes in operating assets and liabilities	$	(117,311	)	$	(108,727	)	$	(8,584	)

Cash used due to changes in operating assets and liabilities during the six months ended June 30, 2019, as compared to the same period in the prior year, increased approximately $8.6 million primarily due to the impact of the cash used for increases in inventory to meet anticipated demand, the increase in accounts receivable primarily as a result of revenue growth, lower accounts payable due to timing of purchases, and lower deferred revenue balances as a result of fewer instrument placements under our instrument rebate programs. These increases in use of cash were partially offset by higher cash provided by our other assets and liabilities, primarily due to lower investment in upfront customer loyalty programs, partially offset by increased investment in volume commitment programs.

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 and the seasonality of vector-borne disease testing, which has historically resulted in significant increases in accounts receivable balances during the first quarter of the year.

Investing Activities. Cash used by investing activities was $72.3 million for the six months ended June 30, 2019, as compared to cash provided by investing activities of $232.7 million for the same period in the prior year. This change in investing cash activity was primarily due to the sale of marketable securities in 2018, as a result of our repatriation of cash and investments held by our foreign subsidiaries, as well as increased capital spending as we expand our Westbrook, Maine headquarters and relocate our core reference laboratory in Germany.

Financing Activities. Cash used by financing activities was $112.3 million for the six months ended June 30, 2019, as compared to cash used by financing activities of $395.7 million for the same period in the prior year. The decrease in cash used by financing activities was due to a decrease in repurchases of our common stock in the current period as compared to the same period in the prior year, an issuance of $100 million senior notes during the first quarter of 2019, and a larger repayment on our revolving Credit Facility in 2018 from repatriated foreign cash.

Cash used to repurchase shares of our common stock decreased $114.9 million during the six months ended June 30, 2019, as compared to the same period in the prior year. 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 activities and

the share price. See Note 11 to the unaudited condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for additional information about our share repurchases.

Net repayment activity under our Credit Facility resulted in cash used of $147.5 million during the six months ended June 30, 2019, as compared to $218.0 million of cash used in the same period of the prior year. At June 30, 2019, we had $251.5 million outstanding under the Credit Facility. The general availability of funds under our Credit Facility was further reduced by $1.3 million for a letter of credit that was issued in connection with claims under our workers’ compensation policy. 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, certain restrictive agreements and violations of laws and regulations. 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.

On March 14, 2019, we amended our Existing Agreement with MetLife, submitted a request for purchase and drew $100 million of our Shelf Notes at 4.19% interest per annum rate, due March 14, 2029 (the "Series C Notes"). Series C Notes proceeds were used for general corporate purposes, including a partial repayment of our Credit Facility.

Since December 2013, we have issued and sold through private placements senior notes having an aggregate principal amount of approximately $700 million, including the $100 million Series C Notes, pursuant to certain note purchase agreements (collectively, the “Senior Note Agreements”). 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, certain restrictive agreements and violations of laws and regulations.

Should we elect to prepay the 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 and cross-acceleration to specified indebtedness.

Effect of Currency Translation on Cash. The net effect of changes in foreign currency exchange rates are 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 the foreign currencies changes. A currency’s value depends on many factors, including interest rates and the country’s 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.

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 and certain other non-cash charges (“Adjusted EBITDA”) not to exceed 3.5-to-1. At June 30, 2019, we were in compliance with such covenant. The following details our consolidated leverage ratio calculation:

Net debt	$	845,589

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 at June 30, 2019, are described in Note 15 to the unaudited condensed consolidated financial statements in Part I, Item 1 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, see the section under the heading “Part II, Item 7A. Quantitative and Qualitative Disclosure About Market Risk” of our 2018 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 2018 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, 2019, as compared to 21% and 22% for the three and six months ended June 30, 2018, 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. Based on projected revenues and expenses for the remainder of 2019, 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 $4 million and operating income by approximately $2 million. Additionally, we project our foreign currency hedge contracts in place as of June 30, 2019, would result in incremental offsetting gains of approximately $1 million. The impact of the intercompany and trade balances, and monetary balances referred to in the third component above have been excluded, as they are transacted at multiple times during the year and we are not able to reliably forecast the impact that changes in exchange rates would have on such balances.

At our current foreign currency exchange rate assumptions, we anticipate the effect of a stronger U.S. dollar for the remainder of the year will have an unfavorable impact on our operating results by decreasing our revenues, operating profit, and diluted earnings per share for the year ending December 31, 2019, by approximately $39 million, $5 million, and $0.04 per share, respectively. This unfavorable currency impact includes a favorable impact of approximately $12 million from foreign currency hedging activity. 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 $1.11, the British pound at $1.23, the Canadian dollar at $0.75, and the Australian dollar at $0.68; and the Japanese yen at ¥110, the Chinese renminbi at RMB 6.97 and the Brazilian real at R$3.85 relative to the U.S. dollar for the remainder of 2019.

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

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 is 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 at June 30, 2019, our Interim 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, 2019, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Effective June 28, 2019, the Board of Directors appointed Jay Mazelsky as our Interim President and Chief Executive Officer. In such role, Mr. Mazelsky will be our Principal Executive Officer.

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 2018 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 2018 Annual Report. The risks described in our 2018 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.

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

During the three months ended June 30, 2019, 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, 2019	49,870		$	224.24	49,870	2,895,568
May 1 to May 31, 2019	25,830		$	248.39	25,830	2,869,738
June 1 to June 30, 2019	10,957		$	260.68	10,280	2,859,458
Total	86,657	⁽²⁾	$	236.04	85,980	2,859,458

The total shares repurchased include shares purchased in the open market and shares surrendered for employee statutory tax withholding. See Note 11 to the unaudited condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for additional information about our share repurchases.

(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 May 2, 2017, the maximum level of shares that may be repurchased under the program was increased from 65 million to 68 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, 2019, and no share repurchase programs expired during the period. Repurchases of 85,980 shares were made during the three months ended June 30, 2019, in transactions made pursuant to our share repurchase program.

(2)

During the three months ended June 30, 2019, we received 677 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 and settlement of deferred 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.
