NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Dollars, except per share amounts, and shares in thousands)

(Unaudited)

Note 1. General

Basis of Presentation

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary to present fairly the financial position of Patterson Companies, Inc. (referred to herein as "Patterson" or in the first person notations "we," "our," and "us") as of January 27, 2018, and our results of operations and cash flows for the periods ended January 27, 2018 and January 28, 2017. Such adjustments are of a normal recurring nature. The results of operations for the periods ended January 27, 2018 and January 28, 2017 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the financial statements included in our 2017 Annual Report on Form 10-K filed on June 28, 2017.

The unaudited condensed consolidated financial statements include the assets and liabilities of PDC Funding Company, LLC ("PDC Funding") and PDC Funding Company II, LLC ("PDC Funding II"), which are our wholly owned subsidiaries and separate legal entities formed under Minnesota law. PDC Funding and PDC Funding II are fully consolidated special purpose entities established to sell customer installment sale contracts to outside financial institutions in the normal course of their business. The assets of PDC Funding and PDC Funding II would be available first and foremost to satisfy the claims of its creditors. There are no known creditors of PDC Funding or PDC Funding II.

Fiscal Year End

We operate with a 52-53 week accounting convention with our fiscal year ending on the last Saturday in April. The third quarter of fiscal 2018 and 2017 represents the 13 weeks ended January 27, 2018 and the 13 weeks ended January 28, 2017, respectively. The nine months ended January 27, 2018 and January 28, 2017 each included 39 weeks. Fiscal 2018 will include 52 weeks and fiscal 2017 included 52 weeks.

Comprehensive Income

Comprehensive income is computed as net income including certain other items that are recorded directly to stockholders’ equity. Significant items included in comprehensive income are foreign currency translation adjustments and the effective portion of cash flow hedges, net of tax. Foreign currency translation adjustments do not include a provision for income tax because earnings from foreign operations are considered to be indefinitely reinvested outside the U.S. The income tax expense related to cash flow hedges was $265 and $265 for the three months ended January 27, 2018 and January 28, 2017, respectively. The income tax expense related to cash flow hedges was $795 and $792 for the nine months ended January 27, 2018 and January 28, 2017, respectively.

Earnings Per Share

The following table sets forth the computation of the weighted average shares outstanding used to calculate basic and diluted earnings per share ("EPS"):



	Three Months Ended		Nine Months Ended
	January 27, 2018	January 28, 2017	January 27, 2018	January 28, 2017
Denominator for basic earnings per share – weighted average shares	91,949	94,737	92,674	95,252
Effect of dilutive securities – stock options, restricted stock and stock purchase plans	660	622	649	663
Denominator for diluted earnings per share – weighted average shares	92,609	95,359	93,323	95,915

Table of Contents

Potentially dilutive securities representing 1,568 and 1,354 shares for the three and nine months ended January 27, 2018, respectively, and 1,499 and 1,261 shares for the three and nine months ended January 28, 2017, respectively, were excluded from the calculation of diluted earnings per share because their effects were anti-dilutive.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers (Topic 606)". ASU No. 2014-09 supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)," and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB deferred the effective date of this pronouncement by one year to December 15, 2017 for annual reporting periods beginning after that date. Companies may use either a full retrospective or a modified retrospective approach to adopt the standard. We plan to adopt the new guidance in the first quarter of fiscal 2019 and are currently evaluating the standard, including the method we will use for adoption and the effect it will have on our financial statements. We do not expect the standard to materially affect our consolidated net earnings, financial position, or cash flows. We are currently evaluating the new standard as it relates to certain sales transactions in which products are shipped directly from the vendor to our customers. We currently report these sales on a gross basis, and are evaluating if we will be required to report these sales on a net basis. Such sales represent approximately 2% of our consolidated net sales. Any change to net presentation would not impact gross margin or earnings.

In July 2015, the FASB issued ASU No. 2015-11, "Inventory (Topic 330), Simplifying the Measurement of Inventory." ASU 2015-11 requires inventory measured using any method other than LIFO or the retail inventory method to be subsequently measured at the lower of cost or net realizable value, rather than at the lower of cost or market. Subsequent measurement of inventory using the LIFO and retail inventory method is unchanged. During the first quarter of fiscal 2018, we adopted ASU No. 2015-11 and it had no material impact to the condensed consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments- Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10)", which amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments, including the requirement to measure certain equity investments at fair value with changes in fair value recognized in net income. We are required to adopt the ASU No. 2016-01 in the first quarter of fiscal 2019. We are evaluating the impact of adopting this pronouncement.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by most leases, as well as requires additional qualitative and quantitative disclosures. We are required to adopt ASU 2016-02 in the first quarter of fiscal 2020, with early adoption permitted. We plan to adopt the new guidance in the first quarter of fiscal 2020 and are currently evaluating the impact of adopting this pronouncement.

In February 2018, the FASB issued ASU No. 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which will allow a reclassification from accumulated other comprehensive income to retained earnings for the tax effects that are stranded in accumulated other comprehensive income as a result of tax reform. This standard also requires certain disclosures about stranded tax effects. We are required to adopt ASU No. 2018-02 in the first quarter of fiscal 2020, with early adoption permitted and apply it either in the period of adoption or retrospectively to each period in which the income tax effects of the tax reform related to items in accumulated other comprehensive income are recognized. We are currently evaluating the impact of adopting this pronouncement.

Note 2. Customer Financing

As a convenience to our customers, we offer several different financing alternatives, including a third party program and a Patterson-sponsored program. For the third party program, we act as a facilitator between the customer and the third party financing entity with no on-going involvement in the financing transaction. Under the Patterson-sponsored program, equipment purchased by creditworthy customers may be financed up to a maximum of $1,000. We generally sell our customers’ financing contracts to outside financial institutions in the normal course of our business. These financing arrangements are accounted for as a sale of assets under the provisions of ASC 860, Transfers and Servicing. We currently have two arrangements under which we sell these contracts.

Table of Contents

First, we operate under an agreement to sell a portion of our equipment finance contracts to commercial paper conduits with The Bank of Tokyo-Mitsubishi UFJ, Ltd. ("BTMU") serving as the agent. We utilize PDC Funding to fulfill a requirement of participating in the commercial paper conduit. We receive the proceeds of the contracts upon sale to BTMU. At least 9.5% of the proceeds are held by the conduit as security against eventual performance of the portfolio. This percentage can be greater and is based upon certain ratios defined in the agreement with BTMU. The capacity under the agreement with BTMU at January 27, 2018 was $575,000.

Second, we maintain an agreement with Fifth Third Bank ("Fifth Third") whereby Fifth Third purchases customers’ financing contracts. PDC Funding II sells its financing contracts to Fifth Third. We receive the proceeds of the contracts upon sale to Fifth Third. At least 11.0% of the proceeds are held by the conduit as security against eventual performance of the portfolio. This percentage can be greater and is based upon certain ratios defined in the agreement with Fifth Third. The capacity under the agreement with Fifth Third at January 27, 2018 was $100,000.

We service the financing contracts under both arrangements, for which we are paid a servicing fee. The servicing fees we receive are considered adequate compensation for services rendered. Accordingly, no servicing asset or liability has been recorded.

The portion of the purchase price for the receivables held by the conduits is deemed a deferred purchase price receivable, which is paid to the applicable special purpose entity as payments on the customers’ financing contracts are collected by Patterson from customers. The difference between the carrying amount of the receivables sold under these programs and the sum of the cash and fair value of the deferred purchase price receivables received at time of transfer is recognized as a gain on sale of the related receivables and recorded in net sales in the condensed consolidated statements of income and other comprehensive income. Expenses incurred related to customer financing activities are recorded in operating expenses in our condensed consolidated statements of income and other comprehensive income.

During the three months ended January 27, 2018 and January 28, 2017, we sold $45,361 and $106,272 of contracts under these arrangements, respectively. During the nine months ended January 27, 2018 and January 28, 2017, we sold $197,072 and $278,529 of contracts under these arrangements, respectively. In net sales in the condensed consolidated statements of income and other comprehensive income, we recorded a loss of $1,688 during the three months ended January 27, 2018, and a gain of $2,450 during the three months ended January 28, 2017 related to these contracts sold. In net sales in the condensed consolidated statements of income and other comprehensive income, we recorded a gain of $8,539 and $16,966 during the nine months ended January 27, 2018 and January 28, 2017, respectively, related to these contracts sold.

Included in cash and cash equivalents in the condensed consolidated balance sheets are $36,009 and $17,902 as of January 27, 2018 and April 29, 2017, respectively, which represent cash collected from previously sold customer financing contracts that have not yet been settled. Included in current receivables in the condensed consolidated balance sheets are $114,521, net of unearned income of $0, and $124,098, net of unearned income of $940, as of January 27, 2018 and April 29, 2017, respectively, of finance contracts we have not yet sold. A total of $581,291 of finance contracts receivable sold under the arrangements was outstanding at January 27, 2018. The deferred purchase price receivable under the arrangements was $137,054 and $119,798 as of January 27, 2018 and April 29, 2017, respectively. Since the internal financing program began in 1994, bad debt write-offs have amounted to less than 1% of the loans originated.

The arrangements require us to maintain a minimum current ratio and maximum leverage ratio. We were in compliance with those covenants at January 27, 2018.

Note 3. Derivative Financial Instruments

We are a party to certain offsetting and identical interest rate cap agreements entered into to fulfill certain covenants of the equipment finance contract sale agreements. The interest rate cap agreements also provide a credit enhancement feature for the financing contracts sold by PDC Funding and PDC Funding II to the commercial paper conduit.

The interest rate cap agreements are canceled and new agreements are entered into periodically to maintain consistency with the dollar maximum of the sale agreements and the maturity of the underlying financing contracts. As of January 27, 2018, PDC Funding had purchased an interest rate cap from a bank with a notional amount of $575,000 and a maturity date of July 2025. We sold an identical interest rate cap to the same bank. As of January 27,

Table of Contents

2018, PDC Funding II had purchased an interest rate cap from a bank with a notional amount of $100,000 and a maturity date of July 2025. We sold an identical interest rate cap to the same bank.

These interest rate cap agreements do not qualify for hedge accounting treatment and, accordingly, we record the fair value of the agreements as an asset or liability and the change as income or expense during the period in which the change occurs.

In March 2008, we entered into two forward starting interest rate swap agreements, each with notional amounts of $100,000 and accounted for as cash flow hedges, to hedge interest rate fluctuations in anticipation of the issuance of the senior notes due fiscal 2015 and fiscal 2018. Upon issuance of the hedged debt, we settled the forward starting interest rate swap agreements and recorded a $1,000 increase, net of income taxes, to other comprehensive income (loss), which is being amortized as a reduction to interest expense over the life of the related debt.

In January 2014, we entered into a forward interest rate swap agreement with a notional amount of $250,000 and accounted for as cash flow hedge, to hedge interest rate fluctuations in anticipation of refinancing the 5.17% senior notes due March 25, 2015. These notes were repaid on March 25, 2015 and replaced with new $250,000 3.48% senior notes due March 24, 2025. A cash payment of $29,003 was made in March 2015 to settle the interest rate swap. This amount is recorded in other comprehensive income (loss), net of tax, and is recognized as interest expense over the life of the related debt.

The following presents the fair value of derivative instruments included in the condensed consolidated balance sheets:



Derivative type	Classification	January 27, 2018		April 29, 2017
Assets:
Interest rate cap agreements	Other noncurrent assets	$	1,061	$	1,188
Liabilities:
Interest rate cap agreements	Other noncurrent liabilities	1,061		1,188

The following table presents the pre-tax effect of derivative instruments in cash flow hedging relationships on the condensed consolidated statements of income and other comprehensive income ("OCI"):



		Amount of Gain (Loss) Reclassified from Accumulated Other Comprehensive Loss into Income (Effective Portion)
		Three Months Ended						Nine Months Ended
Derivatives in cash flow hedging relationships	Income statement location	January 27, 2018			January 28, 2017			January 27, 2018			January 28, 2017
Interest rate swap	Interest expense	$	(702	)	$	(702	)	$	(2,107	)	$	(2,099	)

We recorded no effective portion of gains or losses on derivative instruments in cash flow hedging relationships in OCI during the current period.

We recorded no ineffectiveness during the three and nine month periods ended January 27, 2018 and January 28, 2017. As of January 27, 2018, the estimated pre-tax portion of accumulated other comprehensive loss that is expected to be reclassified into earnings over the next twelve months is $2,885, which will be recorded as an increase to interest expense.

Note 4. Fair Value Measurements

Fair value is the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties. The fair value hierarchy of measurements is categorized into one of three levels based on the lowest level of significant input used:

Level 1 - Quoted prices in active markets for identical assets and liabilities at the measurement date.

Table of Contents

Level 2 - Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 - Unobservable inputs for which there is little or no market data available. These inputs reflect management’s assumptions of what market participants would use in pricing the asset or liability.

Our hierarchy for assets and liabilities measured at fair value on a recurring basis is as follows:



	January 27, 2018
	Total		Level 1		Level 2		Level 3
Assets:
Cash equivalents	$	3,401	$	3,401	$	—	$	—

Cash equivalents – We value cash equivalents at their current market rates. The carrying value of cash equivalents approximates fair value and maturities are less than three months.

Deferred purchase price receivable – We value the deferred purchase price receivable based on a discounted cash flow analysis using unobservable inputs, which include a forward yield curve, the estimated timing of payments and the credit quality of the underlying creditor. Significant changes in any of the significant unobservable inputs in isolation would not result in a materially different fair value estimate. The interrelationship between these inputs is insignificant.

Derivative instruments – Our derivative instruments consist of interest rate cap agreements and interest rate swaps. These instruments are valued using inputs such as interest rates and credit spreads.

Certain assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments under certain circumstances, such as when there is evidence of impairment. There were no fair value adjustments to such assets during the nine month period ended January 27, 2018. During the nine month period ended January 28, 2017, we recorded a non-cash impairment charge of $36,312 related to a distribution agreement intangible asset. Refer to Note 6 for more information.

Our debt is not measured at fair value in the condensed consolidated balance sheets. The estimated fair value of our debt as of January 27, 2018 and April 29, 2017 was $1,013,300 and $1,025,761, respectively, as compared to a carrying value of $1,006,173 and $1,013,026 at January 27, 2018 and April 29, 2017, respectively. The fair value of debt was measured using a discounted cash flow analysis based on expected market based yields (i.e., level 2 inputs).

The carrying amounts of receivables, net of allowances, accounts payable, and certain accrued and other current liabilities approximated fair value at January 27, 2018 and April 29, 2017.

Note 5. Income Taxes

The effective income tax rate for the three months ended January 27, 2018 was (170.0)% compared to 23.2% for the three months ended January 28, 2017, and for the nine months ended January 27, 2018 was (20.9)% compared to 31.9% for the nine months ended January 28, 2017.

The tax benefit for the three and nine months ended January 27, 2018 was primarily due to the impact of the Tax Cuts and Jobs Act ("Tax Act"), enacted on December 22, 2017 by the U.S. government. The Tax Act significantly revises the future ongoing U.S. federal corporate income tax by, among other things, lowering U.S. federal corporate tax rates and implementing a territorial tax system. Effective January 1, 2018, the Tax Act reduced the U.S. federal corporate tax rate from 35.0% to 21.0%. For our fiscal year ending April 28, 2018, we will utilize a blended rate of approximately 30.5%. For the quarter ended January 27, 2018, these impacts resulted in a provisional discrete net tax benefit of $77,256, which included provisional amounts of $81,206 of tax benefit on U.S. deferred tax assets and liabilities and $3,950 of tax expense for a one-time transition tax on unremitted foreign earnings.

The legislative changes included in the Tax Act are broad and complex. We determined that the transition tax on unremitted foreign earnings is provisional because various components of the computation are unknown as of January 27, 2018. In addition, we determined that the impact of the U.S. federal corporate income tax rate change on the U.S. deferred tax assets and liabilities is provisional because the amount cannot be calculated until the underlying timing differences are known rather than estimated.

Given the Tax Act’s significant changes and potential opportunities to repatriate cash tax free, we are in the process of evaluating our current indefinite assertions with regard to cash and earnings that have been subjected to the transition tax. We continue to apply ASC 740 based on the provisions of the tax law that were in effect immediately prior to the enactment of the Tax Act. With regard to unremitted earnings of foreign subsidiaries that have not been previously taxed, we do not currently provide for U.S. taxes since we intend to invest such undistributed earnings indefinitely outside of the U.S.

We continue to review the anticipated impacts of the global intangible low taxed income (“GILTI”) and base erosion and anti-abuse tax (“BEAT”) provisions which are not effective until fiscal year 2019. We have not recorded any impact associated with either GILTI or BEAT in the tax rate for the three months ended January 27, 2018.

The final transition impacts of the Tax Act may differ from the above estimate, possibly materially, due to, among other things, changes in interpretations of the Tax Act, any federal and/or state legislative action to address questions that arise because of the Tax Act, any changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates we have utilized to calculate the transition impacts, including impacts from changes to current year earnings estimates and foreign exchange rates of foreign subsidiaries. The Securities and Exchange Commission has issued rules that will allow for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impacts.

Note 6. Intangible Asset Impairment

In 2006, we extended our exclusive North American distribution relationship with Sirona Dental Systems for Sirona’s CEREC 3D dental restorative system. At that time, we paid a $100,000 distribution fee to extend the existing exclusive relationship for at least a 10-year period beginning in 2007. This distribution fee was accounted for as an intangible asset and amortized since 2007.

Based on our November 2016 decision not to extend sales exclusivity for the full Sirona portfolio of products, we recorded a pre-tax non-cash impairment charge of $36,312 in our Dental segment in the third quarter of fiscal 2017, related to the distribution fee associated with the CEREC product component of this arrangement. This charge was recorded within operating expenses in the condensed consolidated statements of income and other comprehensive income.

Note 9. Legal Proceedings

In September 2015, we were served with a summons and complaint in an action commenced in the U.S. District Court for the Eastern District of New York, entitled SourceOne Dental, Inc. v. Patterson Companies, Inc., Henry Schein, Inc. and Benco Dental Supply Company, Civil Action No. 15-cv-05440-JMA-GRB. SourceOne, as plaintiff, alleges that, through its website, it markets and sells dental supplies and equipment to dentists. SourceOne alleges in the complaint, among other things, that we, along with the defendants Henry Schein and Benco, conspired to eliminate plaintiff as a competitor and to exclude them from the market for the marketing, distribution and sale of dental supplies and equipment in the U.S. and that defendants unlawfully agreed with one another to boycott dentists, manufacturers, and state dental associations that deal with, or considered dealing with, plaintiff. Plaintiff asserts the following claims: (i) unreasonable restraint of trade in violation of state and federal antitrust laws; (ii) tortious interference with prospective business relations; (iii) civil conspiracy; and (iv) aiding and abetting the other defendants’ ongoing tortious and anticompetitive conduct. Plaintiff seeks equitable relief, compensatory and treble damages, jointly and severally, punitive damages, interest, and reasonable costs and expenses, including attorneys’ fees and expert fees. In June 2017, Henry Schein settled with SourceOne and was dismissed from this litigation with prejudice. We are vigorously defending ourselves in this litigation. We do not anticipate that this matter will have a material adverse effect on our financial statements.

Beginning in January 2016, purported class action complaints were filed against defendants Henry Schein, Inc., Benco Dental Supply Company and Patterson Companies, Inc. Although there were factual and legal variations among these complaints, each alleged that defendants conspired to foreclose and exclude competitors by boycotting manufacturers, state dental associations, and others that deal with defendants’ competitors. On February 9, 2016, the U.S. District Court for the Eastern District of New York ordered all of these actions, and all other actions filed thereafter asserting substantially similar claims against defendants, consolidated for pre-trial purposes. On February 26, 2016, a consolidated class action complaint was filed by Arnell Prato, D.D.S., P.L.L.C., d/b/a Down to Earth Dental, Evolution Dental Sciences, LLC, Howard M. May, DDS, P.C., Casey Nelson, D.D.S., Jim Peck, D.D.S., Bernard W. Kurek, D.M.D., Larchmont Dental Associates, P.C., and Keith Schwartz, D.M.D., P.A. (collectively, “putative class representatives”) in the U.S. District Court for the Eastern District of New York, entitled In re Dental Supplies Antitrust Litigation, Civil Action No. 1:16-CV-00696-BMC-GRB. Subject to certain exclusions, the putative class representatives seek to represent all persons who purchased dental supplies or equipment in the U.S. directly from any of the defendants, since August 31, 2008. In the consolidated class action complaint, putative class representatives allege a nationwide agreement among Henry Schein, Benco, Patterson and non-party Burkhart Dental Supply Company, Inc. not to compete on price. The consolidated class action complaint asserts a single count under Section 1 of the Sherman Act, and seeks equitable relief, compensatory and treble damages, jointly and severally, interest, and reasonable costs and expenses, including attorneys’ fees and expert fees. While the outcome of litigation is inherently uncertain, we believe the consolidated class action complaint is without merit, and we are vigorously defending ourselves in this litigation.

to join a price-fixing conspiracy and boycott by reducing the distribution territory of, and eventually terminating, Archer. Archer seeks injunctive relief, and damages in an amount to be proved at trial, to be trebled with interest and costs, including attorneys’ fees, jointly and severally. On March 2, 2018, the case was stayed by the United States Supreme Court pending its decision as to whether to review an arbitration issue raised by the Danaher Defendants. We are vigorously defending ourselves in this litigation. We do not anticipate that this matter will have a material adverse effect on our financial statements.

On August 17, 2017, IQ Dental Supply, Inc. (“IQ Dental”) filed a complaint in the United States District Court for the Eastern District of New York, entitled IQ Dental Supply, Inc. v. Henry Schein, Inc., Patterson Companies, Inc. and Benco Dental Supply Company, Case No. 2:17-cv-4834. Plaintiff alleges that it is a distributor of dental supplies and equipment, and sells dental products through an online dental distribution platform operated by SourceOne Dental, Inc. IQ Dental alleges, among other things, that defendants conspired to suppress competition from IQ Dental and SourceOne for the marketing, distribution and sale of dental supplies and equipment in the United States, and that defendants unlawfully agreed with one another to boycott dentists, manufacturers and state dental associations that deal with, or considered dealing with, plaintiff and SourceOne. Plaintiff claims that this alleged conduct constitutes unreasonable restraint of trade in violation of Section 1 of the Sherman Act, New York’s Donnelly Act and the New Jersey Antitrust Act, and also makes pendant state law claims for tortious interference with prospective business relations, civil conspiracy and aiding and abetting. Plaintiff seeks injunctive relief, compensatory, treble and punitive damages, jointly and severally, and reasonable costs and expenses, including attorneys’ fees and expert fees. On December 21, 2017, the District Court granted defendants motion to dismiss the complaint with prejudice. Plaintiff has appealed to the Fifth Circuit Court of Appeals. We are vigorously defending ourselves in this litigation. We do not anticipate that this matter will have a material adverse effect on our financial statements.

On February 12, 2018, the Federal Trade Commission (“FTC”) issued an administrative complaint entitled In the Matter of Benco Dental Supply Co., Henry Schein, Inc., and Patterson Companies, Inc. Docket No. 9379. The administrative complaint alleges “reason to believe” that Patterson and the other respondents violated Section 5 of the FTC Act, 15 U.S.C. § 45 by conspiring to refuse to offer discounted prices or otherwise negotiate with buying groups seeking to obtain supply agreements on behalf of groups of solo practitioners or small group dental practices. The administrative complaint seeks injunctive relief against Patterson, including an order to cease and desist from the conduct alleged in the complaint and a prohibition from conspiring or agreeing with any competitor or any person to refuse to provide discounts to or compete for the business of any customer. No money damages are sought. We intend to vigorously defend ourselves against the administrative complaint. The administrative complaint provides notice of an October 16, 2018 hearing in front of an Administrative Law Judge of the FTC in Washington, D.C. We do not anticipate this matter will have a material adverse effect on our financial statements.

From time to time, we may become a party to other legal proceedings, including, without limitation, product liability claims, intellectual property claims, employment matters, commercial disputes, governmental inquiries and investigations (which may in some cases involve our entering into settlement arrangements or consent decrees), and other matters arising out of the ordinary course of our business. While the results of any legal proceeding cannot be predicted with certainty, in our opinion none of these other pending matters is anticipated to have a material adverse effect on our financial statements.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This Form 10-Q for the period ended January 27, 2018, contains certain forward-looking statements, as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements are information of a non-historical nature and are subject to risks and uncertainties that are beyond Patterson’s ability to control. Forward-looking statements generally can be identified by words such as “believes,” “expects,” “anticipates,” “foresees,” “forecasts,” “estimates” or other words or phrases of similar import. It is uncertain whether any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do, what impact they will have on the results of operations and financial condition of Patterson or the price of Patterson stock. These forward-looking statements involve certain risks and uncertainties that could cause actual results to differ materially from those indicated in such forward-looking statements. Such risks and uncertainties include, without limitation, the cautionary language set forth herein; operations disruptions attributable to our enterprise resource planning system implementation; our ability to attract or retain qualified sales representatives and service technicians who relate directly with our customers; the reduction,

modification, cancellation or delay of purchases of innovative, high-margin equipment; material changes in our purchasing relationships with suppliers; changes in general market and economic conditions; and the other risks and important factors contained and identified in Patterson’s previous filings with the Securities and Exchange Commission, such as its Quarterly Reports on Form 10-Q and Annual Reports on Form 10-K, any of which could cause actual results to differ materially from the forward-looking statements.

OVERVIEW

Our financial information for the first nine months of fiscal 2018 is summarized in this Management’s Discussion and Analysis and the Condensed Consolidated Financial Statements and related Notes. The following background is provided to readers to assist in the review of our financial information.

We present three reportable segments: Dental, Animal Health and Corporate. Dental and Animal Health are strategic business units that offer similar products and services to different customer bases. Dental provides a virtually complete range of consumable dental products, equipment and software, turnkey digital solutions and value-added services to dentists and dental laboratories throughout North America. Animal Health is a leading, full-line distributor in North America and the U.K. of animal health products, services and technologies to both the production-animal and companion-pet markets. Our Corporate segment is comprised of general and administrative expenses, including home office support costs in areas such as information technology, finance, legal, human resources and facilities. In addition, customer financing and other miscellaneous sales are reported within Corporate results.

Operating margins of the animal health business are considerably lower than the dental business. While operating expenses run at a lower rate in the animal health business when compared to the dental business, gross margins in the animal health business are substantially lower due generally to the low margins experienced on the sale of pharmaceutical products.

We believe there are several important aspects of our business that are useful in analyzing it, including: (1) growth in the various markets in which we operate; (2) internal growth; (3) growth through acquisition; and (4) continued focus on controlling costs and enhancing efficiency. Management defines internal growth as the increase in net sales from period to period, adjusting for differences in the number of weeks in fiscal years, excluding the impact of changes in currency exchange rates, and excluding the net sales, for a period of twelve months following the transaction date, of businesses we have acquired.

FACTORS AFFECTING OUR RESULTS

Enterprise Resource Planning System Initiatives. In the third quarter of fiscal 2017, we completed the application development stage of our enterprise resource planning ("ERP") system, and we began depreciating our investment in such system. We incurred lower operating expenses of approximately $5.0 million in the three months ended January 27, 2018 as compared to the three months ended January 28, 2017 related to this implementation. We incurred increased depreciation and other operating expenses of approximately $6.0 million in the nine months ended January 27, 2018 as compared to the nine months ended January 28, 2017 related to this implementation.

Intangible Asset Impairment. In 2006, we extended our exclusive North American distribution relationship with Sirona Dental Systems for Sirona’s CEREC 3D dental restorative system. At that time, we paid a $100.0 million distribution fee to extend the existing exclusive relationship for at least a 10-year period beginning in 2007. This distribution fee was accounted for as an intangible asset and amortized since 2007. Based on our November 2016 decision not to extend sales exclusivity for the full Sirona portfolio of products, we recorded a pre-tax non-cash impairment charge of $36.3 million, or $23.0 million after taxes or $0.24 per diluted share in our Dental segment in the third quarter of fiscal 2017, related to the distribution fee associated with the CEREC product component of this arrangement.

U.S. Tax Reform. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (“Tax Act”). The Tax Act significantly revises the future ongoing U.S. federal corporate income tax by, among other things, lowering U.S. federal corporate tax rates and implementing a territorial tax system. Effective January 1, 2018, the Tax Act reduced the U.S. federal corporate tax rate from 35.0% to 21.0%.

Table of Contents

For our fiscal year ending April 28, 2018, we will utilize a blended rate of approximately 30.5%. For the quarter ended January 27, 2018, these impacts resulted in a provisional discrete net tax benefit of $77.3 million, which included provisional amounts of $81.2 million of tax benefit on U.S. deferred tax assets and liabilities and $4.0 million of tax expense for a one-time transition tax on unremitted foreign earnings.

RESULTS OF OPERATIONS

QUARTER ENDED JANUARY 27, 2018 COMPARED TO QUARTER ENDED JANUARY 28, 2017

Continuing Operations

The following table summarizes our results from continuing operations as a percent of net sales from continuing operations:



	Three Months Ended
	January 27, 2018		January 28, 2017
Net sales	100.0	%	100.0	%
Cost of sales	78.6		76.4
Gross profit	21.4		23.6
Operating expenses	17.8		20.3
Operating income from continuing operations	3.6		3.3
Other income (expense)	(0.7	)	(0.7	)
Income from continuing operations before taxes	2.9		2.6
Income tax expense (benefit)	(5.0	)	0.6
Net income from continuing operations	7.9	%	2.0	%

Net Sales. Consolidated net sales for the three months ended January 27, 2018 were $1,375.2 million, a decrease of 1.6% from $1,397.4 million for the three months ended January 28, 2017. Foreign exchange rate changes had a favorable impact of 1.1% on current quarter sales.

Dental segment sales for the three months ended January 27, 2018 were $577.9 million, a decrease of 7.7% from $626.3 million for the three months ended January 28, 2017. Foreign exchange rate changes had a favorable impact of 0.4% on current quarter sales. Current quarter sales of consumables decreased 7.0%, sales of dental equipment and software decreased 10.2% to $207.0 million, and sales of other dental services and products decreased 3.0%. The decrease in sales was mainly due to changes in our sales force and disruptions resulting from our ERP system initiatives.

Animal Health segment sales for the three months ended January 27, 2018 were $794.9 million, an increase of 4.2% from $762.6 million for the three months ended January 28, 2017. Foreign exchange rate changes had a favorable impact of 1.6% on current quarter sales. Sales of certain products previously recognized on a gross basis were recognized on a net basis during the three months ended January 27, 2018, resulting in an estimated 2.0% unfavorable impact to sales. Positive end market fundamentals contributed to the current quarter sales growth.

Gross Profit. Consolidated gross profit margin rate for the three months ended January 27, 2018 decreased 220 basis points from the prior year quarter to 21.4%. Gross profit margin rates decreased in both the Dental and Animal Health segments during the three months ended January 27, 2018. Unfavorable sales mix and lower rebates in both our Dental and Animal Health segment were the primary drivers of the decline in the gross profit margin rate. In addition, a greater percentage of sales came from our lower margin Animal Health segment during the three months ended January 27, 2018, resulting in a lower consolidated gross profit margin rate.

Operating Expenses. Consolidated operating expenses for the three months ended January 27, 2018 were $244.7 million, a 13.6% decrease from the prior year quarter of $283.2 million. We incurred higher operating expenses during the three months ended January 28, 2017 primarily as a result of the intangible asset impairment charge in our Dental segment. The consolidated operating expense ratio of 17.8% decreased 250 basis points from the prior year quarter.

Table of Contents

The decrease in this ratio was driven by the impairment charge in the prior year quarter, partially offset by lower net sales in the current quarter.

Operating Income From Continuing Operations. For the three months ended January 27, 2018, operating income from continuing operations was $50.0 million, or 3.6% of net sales, as compared to $46.6 million, or 3.3% of net sales for the three months ended January 28, 2017. The increase in operating income from continuing operations was primarily due to the impairment charge in the prior year quarter, partially offset by lower net sales and a lower gross profit margin rate in the current quarter. The increase in operating income from continuing operations as a percent of sales was driven by these same factors. In addition, a greater percentage of sales came from our lower margin Animal Health segment during the three months ended January 27, 2018, which lowered operating income from continuing operations as a percent of sales.

Dental segment operating income was $58.4 million for the three months ended January 27, 2018, an increase of $18.4 million from the prior year quarter. The increase was primarily due to the impairment charge in the prior year quarter, partially offset by lower net sales and a lower gross profit margin rate in the current quarter.

Animal Health segment operating income was $18.0 million for the three months ended January 27, 2018, a decrease of $5.7 million from the prior year quarter. The decrease was primarily due to unfavorable sales mix and lower rebates.

Corporate segment operating loss was $26.4 million for the three months ended January 27, 2018, as compared to a loss of $17.2 million for the three months ended January 28, 2017. The change was driven primarily by a decrease in the gain on sale related to our customer financing programs.

Other Income (Expense). Net other expense for the three months ended January 27, 2018 was $9.7 million, compared to $10.4 million for the three months ended January 28, 2017.

Income Tax Expense (Benefit). The effective income tax rate for the three months ended January 27, 2018 was (170.0)% compared to 23.2% for the three months ended January 28, 2017. The tax benefit for the three months ended January 27, 2018 was primarily due to the impact of the Tax Act.

Net Income and Earnings Per Share From Continuing Operations. Net income from continuing operations for the three months ended January 27, 2018 was $109.0 million, compared to $27.8 million for the three months ended January 28, 2017. Earnings per diluted share from continuing operations were $1.18 in the current quarter compared to $0.29 in the prior year quarter. Weighted average diluted shares outstanding in the current quarter were 92.6 million, compared to 95.4 million in the prior year quarter. The current quarter cash dividend was $0.26 per common share compared to $0.24 in the prior year quarter.

Discontinued Operations

For the three months ended January 27, 2018 and January 28, 2017, net loss from discontinued operations was $0 and $3.2 million, respectively. The net loss incurred during the three months ended January 28, 2017 was due to a change in estimate of the tax impact of the sale of Patterson Medical, which was completed in August 2015.

Net Sales. Consolidated net sales for the nine months ended January 27, 2018 were $4,065.1 million, a 2.0% decrease from $4,148.1 million for the nine months ended January 28, 2017. Foreign exchange rate changes had a favorable impact of 0.2% on current period sales.

Dental segment sales for the nine months ended January 27, 2018 were $1,650.3 million, a 7.4% decrease from $1,782.9 million for the nine months ended January 28, 2017. Foreign exchange rate changes had a favorable impact of 0.2% on current period sales. Current period sales of consumables decreased 5.0%, due primarily to changes in our sales force and disruptions resulting from our ERP system initiatives. Sales of dental equipment and software decreased 14.0% to $504.4 million for the nine months ended January 27, 2018, due primarily to a decrease in sales of digital technology products, which was driven by our decision to broaden our technology equipment portfolio. In addition, we believe that our customers are delaying equipment purchases as they evaluate new digital product offerings. Sales of other dental services and products decreased 0.9% for the nine months ended January 27, 2018.

Animal Health segment sales for the nine months ended January 27, 2018 were $2,394.6 million, a 2.7% increase from $2,332.4 million for the nine months ended January 28, 2017. Foreign exchange rate changes had a favorable impact of 0.2% on current period sales. Sales of certain products previously recognized on a gross basis were recognized on a net basis during the nine months ended January 27, 2018, resulting in an estimated 2.3% unfavorable impact to sales. Positive end market fundamentals contributed to the current period sales growth.

Gross Profit. Consolidated gross profit margin rate for the nine months ended January 27, 2018 decreased 90 basis points from the prior year period to 22.4%. Gross profit margin rates decreased in both the Dental and Animal Health segment. Unfavorable sales mix and lower rebates in both our Dental and Animal Health segment were the primary drivers of the decline in the gross profit margin rate. In addition, a greater percentage of sales came from our lower margin Animal Health segment during the nine months ended January 27, 2018, resulting in a lower consolidated gross profit margin rate.

Operating Expenses. Consolidated operating expenses for the nine months ended January 27, 2018 were $730.9 million, a 5.6% decrease from the prior year period of $774.1 million. We incurred higher operating expenses during the nine months ended January 28, 2017 primarily as a result of the intangible asset impairment charge in our Dental segment. The decrease in consolidated operating expenses for the nine months ended January 27, 2018 was also driven by cost containment efforts, partially offset by increased expenses related to our ERP system initiatives. The consolidated operating expense ratio of 18.0% decreased 70 basis points from the prior year period. The decrease in this ratio was driven by these same factors.

Operating Income From Continuing Operations. For the nine months ended January 27, 2018, operating income from continuing operations was $178.6 million, or 4.4% of net sales, as compared to $191.8 million, or 4.6% of net sales for the nine months ended January 28, 2017. The decrease in operating income from continuing operations was driven by lower net sales and increased expenses related to our ERP system initiatives, partially offset by the intangible asset impairment charge recorded in the nine months ended January 28, 2017 and cost containment efforts. The decrease in operating income from continuing operations as a percent of sales was driven by these same factors. In addition, a greater percentage of sales came from our lower margin Animal Health segment during the nine months ended January 27, 2018, which reduced operating income from continuing operations as a percent of sales.

Table of Contents

Dental segment operating income was $183.2 million for the nine months ended January 27, 2018, an increase of $5.8 million from the prior year period. The increase was primarily due to the impairment charge in the prior year period and cost containment efforts during the nine months ended January 27, 2018, partially offset by lower net sales and increased expenses related to our ERP system initiatives.

Animal Health segment operating income was $57.9 million for the nine months ended January 27, 2018, a decrease of $2.5 million from the prior year period. The decrease was primarily due to increased expenses related to our ERP system initiatives and lower rebates.

Corporate segment operating loss was $62.5 million for the nine months ended January 27, 2018, as compared to a loss of $46.0 million for the nine months ended January 28, 2017. The change was driven primarily by a decrease in the gain on sale related to our customer financing programs, as well as higher expenses due to a separation agreement with our former chief executive officer.

Other Income (Expense), Net. Net other expense was $29.7 million for the nine months ended January 27, 2018, compared to $26.7 million for the nine months ended January 28, 2017. The increase was mainly due to higher interest expense in the current period.

Income Tax Expense (Benefit). The effective income tax rate for the nine months ended January 27, 2018 was (20.9)% compared to 31.9% for the nine months ended January 28, 2017. The tax benefit for the nine months ended January 27, 2018 was primarily due to the impact of the Tax Act.

Net Income and Earnings Per Share From Continuing Operations. Net income from continuing operations for the nine months ended January 27, 2018 was $180.0 million, compared to $112.4 million for the nine months ended January 28, 2017. Earnings per diluted share from continuing operations were $1.93 in the current period compared to $1.17 in the prior year period. Weighted average diluted shares outstanding in the current period were 93.3 million compared to 95.9 million in the prior year period. The current period cash dividend was $0.78 per common share compared to $0.72 in the prior year period.

Discontinued Operations

For the nine months ended January 27, 2018 and January 28, 2017, net loss from discontinued operations was $0 and $3.2 million, respectively. The net loss incurred during the nine months ended January 28, 2017 was due to a change in estimate of the tax impact of the sale of Patterson Medical, which was completed in August 2015.

LIQUIDITY AND CAPITAL RESOURCES

For the nine months ended January 27, 2018, net cash provided by operating activities was $40.0 million, compared to net cash used in operating activities of $12.6 million for the nine months ended January 28, 2017. The net cash provided by operating activities during the nine months ended January 27, 2018 was primarily driven by net income of $180.0 million, partially offset by growth in consumable and equipment inventory. The improvement in operating cash flows for the nine months ended January 27, 2018 was primarily due to increased collections of accounts receivable.

For the nine months ended January 27, 2018, net cash provided by investing activities was $19.4 million, compared to net cash used in investing activities of $1.6 million for the nine months ended January 28, 2017. The change in net cash flows was primarily driven by the sale of a property during the nine months ended January 27, 2018 for $11.6 million, as well as lower additions to property and equipment during the nine months ended January 27, 2018, which was largely due to lower expenditures on our ERP system. Net cash flows for the nine months ended January 27, 2018 were positive primarily due to the collection of $37.1 million of deferred purchase price receivables. We expect to use a total of approximately $40 million for capital expenditures in fiscal 2018.

Net cash used in financing activities for the nine months ended January 27, 2018 was $42.0 million. Uses of cash consisted primarily of $87.5 million for share repurchases and $74.6 million for dividend payments. Cash proceeds included $120.0 million attributed to draws on our revolving line of credit. For the nine months ended January 28, 2017, net cash provided by financing activities was $4.1 million. Cash proceeds included $178.0 million attributed to draws on our revolving line of credit. Uses of cash consisted primarily of $84.7 million for share repurchases and $70.9 million for dividend payments.

Table of Contents

During fiscal 2016, we entered into a credit agreement ("Credit Agreement"), under which the lenders provided us with senior unsecured lending facilities of up to $1.5 billion, consisting of a $1.0 billion unsecured term loan and a $500 million unsecured revolving line of credit. In fiscal 2017, we entered into an amendment of the Credit Agreement (“Amended Credit Agreement”), consisting of a $295.1 million term loan and a $750 million revolving line of credit. Interest on borrowings is variable and is determined as a base rate plus a spread. This spread, as well as a commitment fee on the unused portion of the facility, is based on our leverage ratio, as defined in the Amended Credit Agreement. The term loan and revolving credit facilities will mature no later than January 2022.

As of January 27, 2018, $284.0 million of the Amended Credit Agreement unsecured term loan was outstanding at an interest rate of 2.80%, and $179.0 million was outstanding under the Amended Credit Agreement revolving line of credit at an interest rate of 2.70%. At April 29, 2017, $291.4 million was outstanding under the Amended Credit Agreement unsecured term loan at an interest rate of 2.24%, and $59.0 million was outstanding under the Amended Credit Agreement revolving line of credit at an interest rate of 2.19%.

We expect funds generated from operations, existing cash balances and credit availability under existing debt facilities will be sufficient to meet our working capital needs and to finance strategic initiatives over the remainder of fiscal 2018.

PART II—OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

On August 31, 2012, Archer and White Sales, Inc. (“Archer”) filed a complaint against Henry Schein, Inc. as well as Danaher Corporation and its subsidiaries Instrumentarium Dental, Inc., Dental Equipment, LLC, Kavo Dental Technologies, LLC and Dental Imaging Technologies Corporation (collectively, the “Danaher Defendants”) in the United States District Court for the Eastern District of Texas, Civil Action No. 2:12-CV-00572-JRG, styled as an antitrust action under Section 1 of the Sherman Act, and the Texas Free Enterprise Antitrust Act. Archer alleges a conspiracy between Henry Schein, an unnamed company and the Danaher Defendants to terminate or limit Archer’s distribution rights. On August 1, 2017, Archer filed an amended complaint, adding Patterson Companies, Inc. and Benco Dental Supply Company as defendants, and alleging that Henry Schein, Patterson, Benco and non-defendant Burkhart Dental Supply Company, Inc. conspired to pressure and agreed to enlist their common suppliers, including the Danaher Defendants, to join a price-fixing conspiracy and boycott by reducing the distribution territory of, and eventually terminating, Archer. Archer seeks injunctive relief, and damages in an amount to be proved at trial, to be trebled with interest and costs, including attorneys’ fees, jointly and severally. On March 2, 2018, the case was stayed by the United States Supreme Court pending its decision as to whether to review an arbitration issue raised by the Danaher Defendants. We are vigorously defending ourselves in this litigation. We do not anticipate that this matter will have a material adverse effect on our financial statements.

SourceOne for the marketing, distribution and sale of dental supplies and equipment in the United States, and that defendants unlawfully agreed with one another to boycott dentists, manufacturers and state dental associations that deal with, or considered dealing with, plaintiff and SourceOne. Plaintiff claims that this alleged conduct constitutes unreasonable restraint of trade in violation of Section 1 of the Sherman Act, New York’s Donnelly Act and the New Jersey Antitrust Act, and also makes pendant state law claims for tortious interference with prospective business relations, civil conspiracy and aiding and abetting. Plaintiff seeks injunctive relief, compensatory, treble and punitive damages, jointly and severally, and reasonable costs and expenses, including attorneys’ fees and expert fees. On December 21, 2017, the District Court granted defendants motion to dismiss the complaint with prejudice. Plaintiff has appealed to the Fifth Circuit Court of Appeals. We are vigorously defending ourselves in this litigation. We do not anticipate that this matter will have a material adverse effect on our financial statements.

Customer Financing	9 Months Ended
Customer Financing	Jan. 27, 2018
Receivables [Abstract]
Customer Financing	Customer Financing As a convenience to our customers, we offer several different financing alternatives, including a third party program and a Patterson-sponsored program. For the third party program, we act as a facilitator between the customer and the third party financing entity with no on-going involvement in the financing transaction. Under the Patterson-sponsored program, equipment purchased by creditworthy customers may be financed up to a maximum of $1,000. We generally sell our customers’ financing contracts to outside financial institutions in the normal course of our business. These financing arrangements are accounted for as a sale of assets under the provisions of ASC 860, Transfers and Servicing. We currently have two arrangements under which we sell these contracts. First, we operate under an agreement to sell a portion of our equipment finance contracts to commercial paper conduits with The Bank of Tokyo-Mitsubishi UFJ, Ltd. ("BTMU") serving as the agent. We utilize PDC Funding to fulfill a requirement of participating in the commercial paper conduit. We receive the proceeds of the contracts upon sale to BTMU. At least 9.5% of the proceeds are held by the conduit as security against eventual performance of the portfolio. This percentage can be greater and is based upon certain ratios defined in the agreement with BTMU. The capacity under the agreement with BTMU at January 27, 2018 was $575,000. Second, we maintain an agreement with Fifth Third Bank ("Fifth Third") whereby Fifth Third purchases customers’ financing contracts. PDC Funding II sells its financing contracts to Fifth Third. We receive the proceeds of the contracts upon sale to Fifth Third. At least 11.0% of the proceeds are held by the conduit as security against eventual performance of the portfolio. This percentage can be greater and is based upon certain ratios defined in the agreement with Fifth Third. The capacity under the agreement with Fifth Third at January 27, 2018 was $100,000. We service the financing contracts under both arrangements, for which we are paid a servicing fee. The servicing fees we receive are considered adequate compensation for services rendered. Accordingly, no servicing asset or liability has been recorded. The portion of the purchase price for the receivables held by the conduits is deemed a deferred purchase price receivable, which is paid to the applicable special purpose entity as payments on the customers’ financing contracts are collected by Patterson from customers. The difference between the carrying amount of the receivables sold under these programs and the sum of the cash and fair value of the deferred purchase price receivables received at time of transfer is recognized as a gain on sale of the related receivables and recorded in net sales in the condensed consolidated statements of income and other comprehensive income. Expenses incurred related to customer financing activities are recorded in operating expenses in our condensed consolidated statements of income and other comprehensive income. During the three months ended January 27, 2018 and January 28, 2017, we sold $45,361 and $106,272 of contracts under these arrangements, respectively. During the nine months ended January 27, 2018 and January 28, 2017, we sold $197,072 and $278,529 of contracts under these arrangements, respectively. In net sales in the condensed consolidated statements of income and other comprehensive income, we recorded a loss of $1,688 during the three months ended January 27, 2018, and a gain of $2,450 during the three months ended January 28, 2017 related to these contracts sold. In net sales in the condensed consolidated statements of income and other comprehensive income, we recorded a gain of $8,539 and $16,966 during the nine months ended January 27, 2018 and January 28, 2017, respectively, related to these contracts sold. Included in cash and cash equivalents in the condensed consolidated balance sheets are $36,009 and $17,902 as of January 27, 2018 and April 29, 2017, respectively, which represent cash collected from previously sold customer financing contracts that have not yet been settled. Included in current receivables in the condensed consolidated balance sheets are $114,521, net of unearned income of $0, and $124,098, net of unearned income of $940, as of January 27, 2018 and April 29, 2017, respectively, of finance contracts we have not yet sold. A total of $581,291 of finance contracts receivable sold under the arrangements was outstanding at January 27, 2018. The deferred purchase price receivable under the arrangements was $137,054 and $119,798 as of January 27, 2018 and April 29, 2017, respectively. Since the internal financing program began in 1994, bad debt write-offs have amounted to less than 1% of the loans originated. The arrangements require us to maintain a minimum current ratio and maximum leverage ratio. We were in compliance with those covenants at January 27, 2018.

Income Taxes	9 Months Ended
Income Taxes	Jan. 27, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rate for the three months ended January 27, 2018 was (170.0)% compared to 23.2% for the three months ended January 28, 2017, and for the nine months ended January 27, 2018 was (20.9)% compared to 31.9% for the nine months ended January 28, 2017. The tax benefit for the three and nine months ended January 27, 2018 was primarily due to the impact of the Tax Cuts and Jobs Act ("Tax Act"), enacted on December 22, 2017 by the U.S. government. The Tax Act significantly revises the future ongoing U.S. federal corporate income tax by, among other things, lowering U.S. federal corporate tax rates and implementing a territorial tax system. Effective January 1, 2018, the Tax Act reduced the U.S. federal corporate tax rate from 35.0% to 21.0%. For our fiscal year ending April 28, 2018, we will utilize a blended rate of approximately 30.5%. For the quarter ended January 27, 2018, these impacts resulted in a provisional discrete net tax benefit of $77,256, which included provisional amounts of $81,206 of tax benefit on U.S. deferred tax assets and liabilities and $3,950 of tax expense for a one-time transition tax on unremitted foreign earnings. The legislative changes included in the Tax Act are broad and complex. We determined that the transition tax on unremitted foreign earnings is provisional because various components of the computation are unknown as of January 27, 2018. In addition, we determined that the impact of the U.S. federal corporate income tax rate change on the U.S. deferred tax assets and liabilities is provisional because the amount cannot be calculated until the underlying timing differences are known rather than estimated. Given the Tax Act’s significant changes and potential opportunities to repatriate cash tax free, we are in the process of evaluating our current indefinite assertions with regard to cash and earnings that have been subjected to the transition tax. We continue to apply ASC 740 based on the provisions of the tax law that were in effect immediately prior to the enactment of the Tax Act. With regard to unremitted earnings of foreign subsidiaries that have not been previously taxed, we do not currently provide for U.S. taxes since we intend to invest such undistributed earnings indefinitely outside of the U.S. We continue to review the anticipated impacts of the global intangible low taxed income (“GILTI”) and base erosion and anti-abuse tax (“BEAT”) provisions which are not effective until fiscal year 2019. We have not recorded any impact associated with either GILTI or BEAT in the tax rate for the three months ended January 27, 2018. The final transition impacts of the Tax Act may differ from the above estimate, possibly materially, due to, among other things, changes in interpretations of the Tax Act, any federal and/or state legislative action to address questions that arise because of the Tax Act, any changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates we have utilized to calculate the transition impacts, including impacts from changes to current year earnings estimates and foreign exchange rates of foreign subsidiaries. The Securities and Exchange Commission has issued rules that will allow for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impacts.

Intangible Asset Impairment	9 Months Ended
Intangible Asset Impairment	Jan. 27, 2018
Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Asset Impairment	Intangible Asset Impairment In 2006, we extended our exclusive North American distribution relationship with Sirona Dental Systems for Sirona’s CEREC 3D dental restorative system. At that time, we paid a $100,000 distribution fee to extend the existing exclusive relationship for at least a 10-year period beginning in 2007. This distribution fee was accounted for as an intangible asset and amortized since 2007. Based on our November 2016 decision not to extend sales exclusivity for the full Sirona portfolio of products, we recorded a pre-tax non-cash impairment charge of $36,312 in our Dental segment in the third quarter of fiscal 2017, related to the distribution fee associated with the CEREC product component of this arrangement. This charge was recorded within operating expenses in the condensed consolidated statements of income and other comprehensive income.

Legal Proceedings	9 Months Ended
Legal Proceedings	Jan. 27, 2018
Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings	Legal Proceedings In September 2015, we were served with a summons and complaint in an action commenced in the U.S. District Court for the Eastern District of New York, entitled SourceOne Dental, Inc. v. Patterson Companies, Inc., Henry Schein, Inc. and Benco Dental Supply Company, Civil Action No. 15-cv-05440-JMA-GRB. SourceOne, as plaintiff, alleges that, through its website, it markets and sells dental supplies and equipment to dentists. SourceOne alleges in the complaint, among other things, that we, along with the defendants Henry Schein and Benco, conspired to eliminate plaintiff as a competitor and to exclude them from the market for the marketing, distribution and sale of dental supplies and equipment in the U.S. and that defendants unlawfully agreed with one another to boycott dentists, manufacturers, and state dental associations that deal with, or considered dealing with, plaintiff. Plaintiff asserts the following claims: (i) unreasonable restraint of trade in violation of state and federal antitrust laws; (ii) tortious interference with prospective business relations; (iii) civil conspiracy; and (iv) aiding and abetting the other defendants’ ongoing tortious and anticompetitive conduct. Plaintiff seeks equitable relief, compensatory and treble damages, jointly and severally, punitive damages, interest, and reasonable costs and expenses, including attorneys’ fees and expert fees. In June 2017, Henry Schein settled with SourceOne and was dismissed from this litigation with prejudice. We are vigorously defending ourselves in this litigation. We do not anticipate that this matter will have a material adverse effect on our financial statements. Beginning in January 2016, purported class action complaints were filed against defendants Henry Schein, Inc., Benco Dental Supply Company and Patterson Companies, Inc. Although there were factual and legal variations among these complaints, each alleged that defendants conspired to foreclose and exclude competitors by boycotting manufacturers, state dental associations, and others that deal with defendants’ competitors. On February 9, 2016, the U.S. District Court for the Eastern District of New York ordered all of these actions, and all other actions filed thereafter asserting substantially similar claims against defendants, consolidated for pre-trial purposes. On February 26, 2016, a consolidated class action complaint was filed by Arnell Prato, D.D.S., P.L.L.C., d/b/a Down to Earth Dental, Evolution Dental Sciences, LLC, Howard M. May, DDS, P.C., Casey Nelson, D.D.S., Jim Peck, D.D.S., Bernard W. Kurek, D.M.D., Larchmont Dental Associates, P.C., and Keith Schwartz, D.M.D., P.A. (collectively, “putative class representatives”) in the U.S. District Court for the Eastern District of New York, entitled In re Dental Supplies Antitrust Litigation, Civil Action No. 1:16-CV-00696-BMC-GRB. Subject to certain exclusions, the putative class representatives seek to represent all persons who purchased dental supplies or equipment in the U.S. directly from any of the defendants, since August 31, 2008. In the consolidated class action complaint, putative class representatives allege a nationwide agreement among Henry Schein, Benco, Patterson and non-party Burkhart Dental Supply Company, Inc. not to compete on price. The consolidated class action complaint asserts a single count under Section 1 of the Sherman Act, and seeks equitable relief, compensatory and treble damages, jointly and severally, interest, and reasonable costs and expenses, including attorneys’ fees and expert fees. While the outcome of litigation is inherently uncertain, we believe the consolidated class action complaint is without merit, and we are vigorously defending ourselves in this litigation. On August 31, 2012, Archer and White Sales, Inc. (“Archer”) filed a complaint against Henry Schein, Inc. as well as Danaher Corporation and its subsidiaries Instrumentarium Dental, Inc., Dental Equipment, LLC, Kavo Dental Technologies, LLC and Dental Imaging Technologies Corporation (collectively, the “Danaher Defendants”) in the United States District Court for the Eastern District of Texas, Civil Action No. 2:12-CV-00572-JRG, styled as an antitrust action under Section 1 of the Sherman Act, and the Texas Free Enterprise Antitrust Act. Archer alleges a conspiracy between Henry Schein, an unnamed company and the Danaher Defendants to terminate or limit Archer’s distribution rights. On August 1, 2017, Archer filed an amended complaint, adding Patterson Companies, Inc. and Benco Dental Supply Company as defendants, and alleging that Henry Schein, Patterson, Benco and non-defendant Burkhart Dental Supply Company, Inc. conspired to pressure and agreed to enlist their common suppliers, including the Danaher Defendants, to join a price-fixing conspiracy and boycott by reducing the distribution territory of, and eventually terminating, Archer. Archer seeks injunctive relief, and damages in an amount to be proved at trial, to be trebled with interest and costs, including attorneys’ fees, jointly and severally. On March 2, 2018, the case was stayed by the United States Supreme Court pending its decision as to whether to review an arbitration issue raised by the Danaher Defendants. We are vigorously defending ourselves in this litigation. We do not anticipate that this matter will have a material adverse effect on our financial statements. On August 17, 2017, IQ Dental Supply, Inc. (“IQ Dental”) filed a complaint in the United States District Court for the Eastern District of New York, entitled IQ Dental Supply, Inc. v. Henry Schein, Inc., Patterson Companies, Inc. and Benco Dental Supply Company, Case No. 2:17-cv-4834. Plaintiff alleges that it is a distributor of dental supplies and equipment, and sells dental products through an online dental distribution platform operated by SourceOne Dental, Inc. IQ Dental alleges, among other things, that defendants conspired to suppress competition from IQ Dental and SourceOne for the marketing, distribution and sale of dental supplies and equipment in the United States, and that defendants unlawfully agreed with one another to boycott dentists, manufacturers and state dental associations that deal with, or considered dealing with, plaintiff and SourceOne. Plaintiff claims that this alleged conduct constitutes unreasonable restraint of trade in violation of Section 1 of the Sherman Act, New York’s Donnelly Act and the New Jersey Antitrust Act, and also makes pendant state law claims for tortious interference with prospective business relations, civil conspiracy and aiding and abetting. Plaintiff seeks injunctive relief, compensatory, treble and punitive damages, jointly and severally, and reasonable costs and expenses, including attorneys’ fees and expert fees. On December 21, 2017, the District Court granted defendants motion to dismiss the complaint with prejudice. Plaintiff has appealed to the Fifth Circuit Court of Appeals. We are vigorously defending ourselves in this litigation. We do not anticipate that this matter will have a material adverse effect on our financial statements. On February 12, 2018, the Federal Trade Commission (“FTC”) issued an administrative complaint entitled In the Matter of Benco Dental Supply Co., Henry Schein, Inc., and Patterson Companies, Inc. Docket No. 9379. The administrative complaint alleges “reason to believe” that Patterson and the other respondents violated Section 5 of the FTC Act, 15 U.S.C. § 45 by conspiring to refuse to offer discounted prices or otherwise negotiate with buying groups seeking to obtain supply agreements on behalf of groups of solo practitioners or small group dental practices. The administrative complaint seeks injunctive relief against Patterson, including an order to cease and desist from the conduct alleged in the complaint and a prohibition from conspiring or agreeing with any competitor or any person to refuse to provide discounts to or compete for the business of any customer. No money damages are sought. We intend to vigorously defend ourselves against the administrative complaint. The administrative complaint provides notice of an October 16, 2018 hearing in front of an Administrative Law Judge of the FTC in Washington, D.C. We do not anticipate this matter will have a material adverse effect on our financial statements. From time to time, we may become a party to other legal proceedings, including, without limitation, product liability claims, intellectual property claims, employment matters, commercial disputes, governmental inquiries and investigations (which may in some cases involve our entering into settlement arrangements or consent decrees), and other matters arising out of the ordinary course of our business. While the results of any legal proceeding cannot be predicted with certainty, in our opinion none of these other pending matters is anticipated to have a material adverse effect on our financial statements.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary to present fairly the financial position of Patterson Companies, Inc. (referred to herein as "Patterson" or in the first person notations "we," "our," and "us") as of January 27, 2018, and our results of operations and cash flows for the periods ended January 27, 2018 and January 28, 2017. Such adjustments are of a normal recurring nature. The results of operations for the periods ended January 27, 2018 and January 28, 2017 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the financial statements included in our 2017 Annual Report on Form 10-K filed on June 28, 2017. The unaudited condensed consolidated financial statements include the assets and liabilities of PDC Funding Company, LLC ("PDC Funding") and PDC Funding Company II, LLC ("PDC Funding II"), which are our wholly owned subsidiaries and separate legal entities formed under Minnesota law. PDC Funding and PDC Funding II are fully consolidated special purpose entities established to sell customer installment sale contracts to outside financial institutions in the normal course of their business. The assets of PDC Funding and PDC Funding II would be available first and foremost to satisfy the claims of its creditors. There are no known creditors of PDC Funding or PDC Funding II.
Fiscal Year End	Fiscal Year End We operate with a 52-53 week accounting convention with our fiscal year ending on the last Saturday in April. The third quarter of fiscal 2018 and 2017 represents the 13 weeks ended January 27, 2018 and the 13 weeks ended January 28, 2017, respectively. The nine months ended January 27, 2018 and January 28, 2017 each included 39 weeks. Fiscal 2018 will include 52 weeks and fiscal 2017 included 52 weeks.
Comprehensive Income	Comprehensive Income Comprehensive income is computed as net income including certain other items that are recorded directly to stockholders’ equity. Significant items included in comprehensive income are foreign currency translation adjustments and the effective portion of cash flow hedges, net of tax. Foreign currency translation adjustments do not include a provision for income tax because earnings from foreign operations are considered to be indefinitely reinvested outside the U.S.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers (Topic 606)". ASU No. 2014-09 supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)," and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB deferred the effective date of this pronouncement by one year to December 15, 2017 for annual reporting periods beginning after that date. Companies may use either a full retrospective or a modified retrospective approach to adopt the standard. We plan to adopt the new guidance in the first quarter of fiscal 2019 and are currently evaluating the standard, including the method we will use for adoption and the effect it will have on our financial statements. We do not expect the standard to materially affect our consolidated net earnings, financial position, or cash flows. We are currently evaluating the new standard as it relates to certain sales transactions in which products are shipped directly from the vendor to our customers. We currently report these sales on a gross basis, and are evaluating if we will be required to report these sales on a net basis. Such sales represent approximately 2% of our consolidated net sales. Any change to net presentation would not impact gross margin or earnings. In July 2015, the FASB issued ASU No. 2015-11, "Inventory (Topic 330), Simplifying the Measurement of Inventory." ASU 2015-11 requires inventory measured using any method other than LIFO or the retail inventory method to be subsequently measured at the lower of cost or net realizable value, rather than at the lower of cost or market. Subsequent measurement of inventory using the LIFO and retail inventory method is unchanged. During the first quarter of fiscal 2018, we adopted ASU No. 2015-11 and it had no material impact to the condensed consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments- Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10)", which amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments, including the requirement to measure certain equity investments at fair value with changes in fair value recognized in net income. We are required to adopt the ASU No. 2016-01 in the first quarter of fiscal 2019. We are evaluating the impact of adopting this pronouncement. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by most leases, as well as requires additional qualitative and quantitative disclosures. We are required to adopt ASU 2016-02 in the first quarter of fiscal 2020, with early adoption permitted. We plan to adopt the new guidance in the first quarter of fiscal 2020 and are currently evaluating the impact of adopting this pronouncement. In February 2018, the FASB issued ASU No. 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which will allow a reclassification from accumulated other comprehensive income to retained earnings for the tax effects that are stranded in accumulated other comprehensive income as a result of tax reform. This standard also requires certain disclosures about stranded tax effects. We are required to adopt ASU No. 2018-02 in the first quarter of fiscal 2020, with early adoption permitted and apply it either in the period of adoption or retrospectively to each period in which the income tax effects of the tax reform related to items in accumulated other comprehensive income are recognized. We are currently evaluating the impact of adopting this pronouncement.
