NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except share and per share data)

(Unaudited)

July 27, 2013

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 our Company as of July 27, 2013, and our results of operations and cash flows for the periods ended July 27, 2013 and July 28, 2012. Such adjustments are of a normal recurring nature. The results of operations for the periods ended July 27, 2013 and July 28, 2012, 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 the 2013 Annual Report on Form 10-K filed on June 26, 2013.

The condensed consolidated financial statements of Patterson Companies, Inc. include the assets and liabilities of PDC Funding Company, LLC (“PDC Funding”) and PDC Funding Company II, LLC (“PDC Funding II”), wholly owned subsidiaries and separate legal entities under Minnesota law. PDC Funding and PDC Funding II are fully consolidated special purpose entities of our Company established to sell customer installment sale contracts to outside financial institutions in the normal course of 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

The fiscal year end of our Company is the last Saturday in April. The first quarter of fiscal years 2014 and 2013 represents the 13 weeks ended July 27, 2013 and July 28, 2012, respectively. Fiscal years 2014 and 2013 each include 52 weeks of operations.

Comprehensive Income

Other than net income, the only significant items included in comprehensive income are foreign currency translation adjustments. 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.

Earnings Per Share

The following table sets forth the computation of basic and diluted earnings per share (shares in thousands):

	Three Months Ended
	July 27, 2013		July 28, 2012
Denominator:
Denominator for diluted earnings per share—average shares		101,027		105,035
Effect of dilutive securities—stock options, restricted stock, ESOP and stock purchase plans		892		748
Denominator for diluted earnings per share—adjusted weighted average shares		101,919		105,783

Options to purchase 148 shares of common stock during the three months ended July 27, 2013, and 421 shares during the three months ended July 28, 2012, respectively, were excluded from the calculation of diluted earnings per share because the effect would have been anti-dilutive. There were no unvested restricted stock awards excluded from the calculation of diluted earnings per share during the three months ended July 27, 2013, and July 28, 2012, respectively, because the effect would have been anti-dilutive.

Recently Issued Accounting Pronouncements

In July 2012, the FASB issued ASU No. 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment. Under this standard, entities testing long-lived intangible assets for impairment now have an option of performing a qualitative assessment to determine whether further impairment testing is necessary. If an entity determines, on the basis of qualitative factors, that the fair value of the indefinite-lived intangible asset is more-likely-than-not less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. For Patterson, this ASU was effective beginning April 28, 2013. The adoption of this standard did not have a material impact on Patterson’s consolidated results of operations or financial condition.

NOTE 2 GOODWILL AND OTHER INTANGIBLE ASSETS

The goodwill balances and related activity by business segment as of April 27, 2013 and July 27, 2013 are as follows:

					Translation
	Balance at		Acquisition		And Other			Balance at
	April 27, 2013		Activity		Activity			July 27, 2013

Total identifiable intangible assets, net	$	191,810		$	196,656

NOTE 3 DERIVATIVE FINANCIAL INSTRUMENTS

Patterson is a party to certain offsetting and identical interest rate cap agreements. These cap agreements are not designated for hedge accounting treatment and were entered into to fulfill certain covenants of a sale agreement between a commercial paper conduit managed by The Bank of Tokyo-Mitsubishi UFJ, Ltd. and PDC Funding. On November 30, 2012, this agreement was amended on terms consistent with the expiring agreement. The cap agreements provide a credit enhancement feature for the financing contracts sold by PDC Funding to the commercial paper conduit.

The cap agreements are cancelled and new agreements entered into periodically to maintain consistency with the dollar maximum of the sale agreements and the maturity of the underlying financing contracts. As of July 27, 2013, PDC Funding had purchased an interest rate cap from a bank with a notional amount of $500,000 and a maturity date of December 2019. Patterson Companies, Inc. sold an identical interest rate cap to the same bank.

Similar to the above agreements, PDC Funding II, and Patterson Companies, Inc. entered into offsetting and identical interest rate cap agreements with a notional amount of $75,000 in fiscal 2013. In August 2013, these agreements were terminated and replaced with offsetting and identical interest rate cap agreements. The notional amount increased to $100,000 and the new maturity date is January 2021.

7

In addition to the identical purchased and sold interest rate cap agreements described above, in May 2012 we entered into an interest rate swap agreement with a bank to economically hedge the interest rate risk associated with our finance contracts.

Our interest rate contracts 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.

The following table presents the fair value of our interest rate contracts on the consolidated balance sheets:

		July 27,		April 27,		July 28,
Derivative type	Classification	2013		2013		2012
Assets:
Interest rate contracts	Other noncurrent assets	$	1,153	$	486	$	229
Liabilities:
Interest rate contracts	Other noncurrent liabilities	$	1,167	$	509	$	274

The following table presents the effect of interest rate contracts on the consolidated statements of income:

		Three Months Ended
Derivative type	Location of gain (loss) recognized on derivative	July 27, 2013			July 28, 2012
Interest rate contracts	Other income (expense), net	$	(4	)	$	59

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.
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.

8

Our hierarchy for assets and liabilities measured at fair value on a recurring basis as of July 27, 2013 is as follows:

			Quoted Prices in		Significant Other		Significant
			Active Markets		Observable Inputs		Unobservable Inputs
	Total		(Level 1)		(Level 2)		(Level 3)
Assets:
Cash equivalents	$	389,690	$	389,690	$	—	$	—
Derivative instruments		1,153		—		1153		—
Total assets	$	390,843	$	389,690	$	1153	$	—
Liabilities:
Derivative instruments	$	1,167	$	—	$	1167	$	—

Our hierarchy for assets and liabilities measured at fair value on a recurring basis as of April 27, 2013 is as follows:

			Quoted Prices in		Significant Other		Significant
			Active Markets		Observable Inputs		Unobservable Inputs
	Total		(Level 1)		(Level 2)		(Level 3)
Assets:
Cash equivalents	$	282,619	$	282,619	$	—	$	—
Derivative instruments		486		—		486		—
Total assets	$	283,105	$	282,619	$	486	$	—
Liabilities:
Derivative instruments	$	509	$	—	$	509	$	—

Cash equivalents – We value cash equivalents at their current market rates. The carrying value of cash equivalents, including government securities and money market funds, is recorded at fair value and maturities are less than three months.

Derivative instruments – Patterson’s derivative instruments consist of interest rate contracts. 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 periods ended July 27, 2013 or July 28, 2012.

The carrying amounts of receivables, net of allowances, accounts payable, and certain accrued and other current liabilities approximated fair value at July 27, 2013 and July 28, 2012.

NOTE 5 CUSTOMER FINANCING

As a convenience to our customers, we offer several different financing alternatives including both our Company-sponsored program and a third party 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 our sponsored program, equipment purchased by customers with strong credit may be financed up to a maximum of $400 for any one customer. We generally sell the customers’ financing contracts to outside financial institutions in the normal course of our business. Patterson currently has two arrangements under which we sell these contracts.

Patterson operated under an agreement to sell a portion of our equipment finance contracts to commercial paper conduits with The Bank of Tokyo-Mitsubishi UFJ, Ltd. serving as the agent. We utilize a special purpose entity (“SPE”), PDC Funding, a consolidated, wholly owned subsidiary to fulfill a requirement of participating in the commercial paper conduit. We receive approximately 85% of the principal amounts of the contracts upon sale. The remaining 15% of the proceeds are held by the conduit as security against the eventual performance of the portfolio. The capacity under the agreement at July 27, 2013 was $500,000.

9

Patterson also maintains an agreement with Fifth Third Bank whereby the bank purchases customers’ financing contracts. Patterson has established another SPE, PDC Funding II, as a consolidated, wholly owned subsidiary, which sells financing contracts to the bank. We receive approximately 81% of the principal amounts of the contracts upon sale. The remaining 19% of the proceeds is held by the conduit as security against the eventual performance of the portfolio. The capacity under the agreement at July 27, 2013 was $75,000.

The portion of the purchase price for the receivables held by the conduits is a deferred purchase price receivable, which is paid to the SPE as payments on the receivables are collected from customers. The deferred purchase price receivable represents a beneficial interest in the transferred financial assets and is recognized at fair value as part of the sale transaction. The Company values the deferred purchase price receivable based on a discounted cash flow analysis using unobservable inputs (i.e. level 3 inputs), which include a forward yield curve, the estimated timing of payments and the credit quality of the underlying creditor. Significant increases in any of the significant unobservable inputs in isolation would not result in a materially lower fair value estimate. The interrelationship between these inputs is insignificant.

These financing arrangements are accounted for as a sale of assets under the provisions of ASC Topic No. 860, Transfers and Servicing. During the three months ended July 27, 2013 and July 28, 2012, we sold approximately $69,500, and $95,100, respectively, of contracts under these arrangements. Patterson retains servicing responsibilities under both agreements, for which we are paid a servicing fee. The servicing fees received by Patterson are considered adequate compensation for services rendered. Accordingly, no servicing asset or liability has been recorded. The agreements require us to maintain a minimum current ratio and maximum leverage ratio. Patterson was in compliance with the covenants at July 27, 2013.

Included in current receivables in the consolidated balance sheets are approximately $40,290, net of unearned income of $791, and $64,272, net of unearned income of $1,586, as of July 27, 2013 and April 27, 2013, respectively, of finance contracts not yet sold by Patterson. A total of $491,283 of finance contracts receivable sold under the agreements was outstanding at July 27, 2013. The deferred purchase price under the arrangements was approximately $72,493 and $72,328 as of July 27, 2013 and April 27, 2013, respectively. Since the internal financing program began in 1994, bad debt write-offs have amounted to less than one-percent of the loans originated.

NOTE 6 SEGMENT REPORTING

Patterson Companies, Inc. is comprised of three reportable segments: dental, veterinary, and rehabilitation supply. Our reportable business segments are strategic business units that offer similar products and services to different customer bases. The dental supply segment provides a virtually complete range of consumable dental products, clinical and laboratory equipment and value-added services to dentists, dental laboratories, institutions and other dental healthcare providers throughout North America. The veterinary supply segment provides consumable supplies, equipment, diagnostic products, biologicals (vaccines) and pharmaceuticals to companion-pet veterinary clinics throughout the United States. The rehabilitation supply segment provides a comprehensive range of distributed and self-manufactured rehabilitation medical supplies and assistive products to acute care hospitals, long-term care facilities, rehabilitation clinics, dealers and schools.

We evaluate segment performance based on operating income. The corporate office general and administrative expenses are included in the dental supply segment and consist of home office support costs in areas such as informational technology, finance, human resources and facilities. If these corporate expenses were allocated to the segments, the results would not be materially different as the dental segment would absorb a significant portion of these expenses. The costs to operate the distribution centers are allocated to the operating units based on the through-put of each unit.

Total	$	880,125	$	889,225

NOTE 7 EMPLOYEE STOCK OWNERSHIP PLAN (ESOP)

During 1990, our Board of Directors adopted a leveraged ESOP. In fiscal 2002 and 2006, under the provisions of the plan and related financing arrangements, Patterson loaned the ESOP $12,612 (the “2002 note”) and $105,000 (the “2006 note”), respectively. The contribution from the ESOP to employees is determined annually by the Board of Directors. Shares of stock acquired by the plan are allocated to each participant who has completed 1,000 hours of service during the plan year. These shares are accounted for under ASC 718-40, Share-based Payments – Employee Stock Ownership Plans, and are not considered outstanding for computation of earnings per share until the shares are committed for release to the participants. We recognize expense based on the current fair value of the shares released to participants. As of July 27, 2013, a total of 3,018,992 of unallocated shares were held by the ESOP. The ESOP expense recognized during the three months ended July 27, 2013 and July 28, 2012 was $5,700 for both quarters.

NOTE 8 DEBT ISSUANCE

On September 25, 2012, we repaid our $75,000 term loan. This loan was originally scheduled to mature on March 20, 2013. On March 25, 2013, we repaid $50,000 under the 2008 Note Purchase Agreement.

On July 26, 2013, $135,000 was drawn on the revolving line of credit. The proceeds were used to fund the acquisition of National Veterinary Supply (“NVS”), which we closed on August 16, 2013.

11

NOTE 9 Subsequent Event

On August 16, 2013 Patterson Companies, Inc. completed the acquisition of all the outstanding stock of National Veterinary Services Limited (“NVS”) from Dechra Pharmaceuticals, PLC. NVS is the largest veterinary products distributor in the United Kingdom. Total cash consideration paid for NVS was £93,500 (approximately $146,000). £87,500 was paid at closing and an additional £6,000 was paid on August 21, 2013 due to higher working capital balances at NVS on the close date.

On August 22, 2013 the Company announced a plan to divest certain non-core product lines in its medical segment. As a result of the plan to dispose of these product lines, the Company expects to incur a pre-tax restructuring charge in the range of $15,000 to $17,000, or approximately $0.12 per diluted share. Approximately $14,000 to $15,000 of the restructuring charge will be non-cash losses on disposal of assets.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

Our first quarter, fiscal 2014 financial information is summarized in this Management’s Discussion and Analysis, and the Consolidated Financial Statements and related Notes. The following background is essential to fully understanding our Company’s financial information.

Patterson operates a distribution business in three complementary markets: dental supply, veterinary supply and rehabilitation supply. Historically, our strategy for growth focused on internal growth and the acquisition of smaller distributors and businesses offering related products and services to the dental market. In fiscal 2002, we expanded our strategy to take advantage of a parallel growth opportunity in the veterinary supply market by acquiring the assets of J. A. Webster, Inc. on July 9, 2001. Effective January 1, 2013, Webster Veterinary Supply, Inc. changed its name to Patterson Veterinary Supply, Inc. Patterson added a third component to our business platform in fiscal 2004 when it entered the rehabilitation supply market with the acquisition of AbilityOne Products Corp. (“AbilityOne”) on September 12, 2003. AbilityOne is now known as Patterson Medical Holdings, Inc.

Operating margins of the veterinary business are considerably lower than the dental and rehabilitation supply businesses. While operating expenses run at a lower rate in the veterinary business, their gross margin is substantially lower due generally to pharmaceutical products sales, which have margins well below the average sundry product.

There are several important aspects of Patterson’s business that are useful in analyzing it, including: (1) market 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, 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.

On August 16, 2013 Patterson Companies, Inc. completed the acquisition of all the outstanding stock of National Veterinary Services Limited (“NVS”) from Dechra Pharmaceuticals, PLC. NVS is the largest veterinary products distributor in the United Kingdom. Total cash consideration paid for NVS was £93,500 (approximately $146,000). £87,500 was paid at closing and an additional £6,000 was paid on August 21, 2013 due to higher working capital balances at NVS on the close date. The acquisition is expected to be accretive to earnings by $0.03 to $0.04 per diluted share for the remainder of the fiscal year ended April 26, 2014.

On August 22, 2013 the Company announced a plan to divest certain non-core product lines in its medical segment. As a result of the plan to dispose of these product lines, the Company expects to incur a pre-tax restructuring charge in the range of $15,000 to $17,000, or approximately $0.12 per diluted share. Approximately $14,000 to $15,000 of the restructuring charge will be non-cash losses on disposal of assets. The remainder of the restructuring charge will result in cash expenditures in connection with the closing of a facility. A majority of the restructuring charge will be taken in the second quarter of fiscal year 2014. The Company estimates that disposing of these product lines will generate operational savings of approximately $2,000 beginning in fiscal year 2015.

RESULTS OF OPERATIONS

The following table sets forth, for the periods indicated, the percentage of net sales represented by certain operational data.

	Three Months Ended
	July 27, 2013			July 28, 2012
Net sales		100.0	%		100.0	%
Cost of sales		68.0	%		67.9	%
Gross margin		32.0	%		32.1	%
Operating expenses		22.8	%		22.8	%
Operating income		9.2	%		9.3	%
Other expense, net		(1.0	%)		(1.0	%)
Income before taxes		8.2	%		8.3	%
Net income		5.2	%		5.3	%

QUARTER ENDED JULY 27, 2013 COMPARED TO QUARTER ENDED JULY 28, 2012.

Net Sales. Consolidated net sales for the three months ended July 27, 2013 (“Current Quarter”) were $880.1 million, a 1.0% decrease from $889.2 million for the three months ended July 28, 2012 (“Prior Quarter”). Acquisitions contributed 0.2% to Current Quarter sales growth, and foreign exchange rate changes had an unfavorable impact to Current Quarter sales growth of 0.1%.

Sales of the Dental segment were $554.2 million, a 2.3% decrease from $567.4 million from the Prior Quarter. Current Period sales of consumables and printed office products increased an encouraging 3.3%. Sales of dental equipment and software decreased 11.7% to $169.6 million. The Prior Quarter sales of equipment were favorably impacted by strong performance in the CEREC category as the Dental segment was heavily promoting the product. Sales of other services and products in the Dental segment declined 1.4% in the Current Quarter, mainly due to a decline in the gain recognized on the sale of our Finance Receivables. The Current Period had a lower volume of contracts sold compared to the Prior Period and an upward movement on the long-end of the interest rate curve in the Current Period reduced the gain.

Veterinary segment sales rose 4.5% to $199.7 million, due to a 3.8% increase in consumables, such as medication and supplies and an 11.8% increase in equipment and software sales. We believe that our equipment and technology strategy, which includes enhancing our infrastructure and becoming a national technical service provider, is driving the increase.

Rehabilitation segment sales declined 3.5% to $126.2 million, due to a 5.9% decrease in equipment sales. The unfavorable foreign currency translation rates decreased segment sales by 0.4%. Sales of consumables decreased 2.4% in the current quarter. We believe that continued uncertainty surrounding the U.S. health care system and the overall economy as well as continued austerity efforts in the United Kingdom are adversely affecting this segment.

Gross Margins. Consolidated gross margin decreased 10 basis points from the Prior Quarter to 32.0%. Our Dental segment gross margin increased by 30 basis points, mainly due to strong consumable sales in the current period, and lower promotional expenses on the CEREC category. Consumable sales carry a higher gross margin on average than do equipment sales. The Veterinary segment gross margin was flat with prior year, due to stronger equipment sales which provide lower margins. The Rehabilitation segment gross margin declined 80 basis points, due to international channel pressures and sales mix. Consolidated gross margins were negatively impacted by the gain on contract sales.

Operating Expenses. The consolidated operating expense ratio remained consistent with the Prior Quarter at 22.8%. The Medical segment experienced an improved operating expense ratio while the Dental and Veterinary segment operating expense ratio increased. The softness in sales growth is the primary cause for the increase in the operating expense ratio for the Dental segment. The Veterinary segment expense structure includes costs from the increases in sales and technical service personnel as well as acquisition costs for National Veterinary Services, Ltd. (“NVS”) transaction which closed after the close of the quarter. As discussed previously, we continue to invest in people and systems we believe are necessary for the long-term success of the company. The incremental expense in the current period was over $2 million.

Operating Income. Current Quarter operating income was $81.3 million, or 9.2% of net sales. In the Prior Quarter, operating income was $82.6 million, or 9.3% of net sales. The decrease is due primarily to the lower sales levels, making it more difficult to leverage our expense infrastructure compounded by the incremental expenses incurred on acquisitions and system development.

14

Other (Expense) Income, Net. Net other expense was $9.1 million in the Current Quarter compared to $8.9 million in the Prior Quarter. Net other expense is comprised primarily of interest expense, partly offset by interest income. Interest income of $1.2 million was down 10 basis points from the Prior Quarter.

Income Tax Expense. The effective income tax rate for the Current Quarter was 36.4% compared to 35.5% in the Prior Quarter. The increase in the current year rate is due to certain onetime benefits that were included in the prior year rate. For the fiscal year, the income tax rate from recurring operations is expected to be in a range from 35.5% to 35.7% as the Company works through its integration of NVS. Recurring operations excludes the recently announced restructuring in its Medical division. The Current Quarter’s cash dividend was $0.16 per common share compared to $0.14 in the Prior Quarter.

Net Income and Earnings Per Share. Net income was $45.9 million, compared to $47.5 million in the Prior Quarter. Earnings per diluted share was $0.45 in both the Current Quarter and Prior Quarter. Diluted shares outstanding in the Current Quarter were 101,919,000 compared to 105,783,000 in the Prior Quarter. The decrease in the share count is due to share repurchase activity over the past year.

LIQUIDITY AND CAPITAL RESOURCES

Our cash flows from operations in the Current Quarter were $21.1 million compared to $59.8 million in the Prior Quarter primarily as a result of the timing and magnitude of income tax and accounts payable disbursements.

Net cash used in investing activities of $5.6 million in the Current Period compared to $3.2 million in the prior period primarily reflects investments in our IT hardware infrastructure and maintenance capital expenditures for replacements and replenishment. We expect to use a total of approximately $25 million to $30 million for capital expenditures in fiscal 2014.

Cash provided by financing activities during the Current Period was $84.8 million, including $135 million for a draw on our revolver for the purchase of NVS, offset by cash used for dividend payments of $29.8 million and stock repurchases of $22.2 million. In the Prior Period, cash used in financing activities was $45.2 million including stock repurchases of $34.5 million and dividends of $14.8 million.

We expect funds generated by operations, existing cash balances and credit availability under existing debt facilities will be sufficient to meet our working capital needs and to finance anticipated expansion plans and strategic initiatives over the remainder of fiscal 2014.

As of July 27, 2013, $165 million was available under our $300 million revolving credit facility. Our current credit agreement expires in December 2016.

On August 22, 2013 the Company announced a plan to divest certain non-core product lines in its medical segment. As a result of the plan to dispose of these product lines, the Company expects to incur a pre-tax restructuring charge in the range of $15,000 to $17,000, or approximately $0.12 per diluted share. Approximately $14,000 to $15,000 of the restructuring charge will be non-cash losses on disposal of assets. The remainder of the restructuring charge will result in cash expenditures in connection with the closing of a facility. A majority of the restructuring charge will be taken in the second quarter of fiscal year 2014. The Company estimates that disposing of these product lines will generate operational savings of approximately $2,000 beginning in fiscal year 2015.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

In July 2012, the FASB issued ASU No. 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment. Under this standard, entities testing long-lived intangible assets for impairment now have an option of performing a qualitative assessment to determine whether further impairment testing is necessary. If an entity determines, on the basis of qualitative factors, that the fair value of the indefinite-lived intangible asset is more-likely-than-not less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. For Patterson, this ASU was effective beginning April 28, 2013. The adoption of this standard did not have a material impact on Patterson’s consolidated results of operations or financial condition.

FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

In our Form 10-K for the year ended April 27, 2013, we described material risk factors facing our business. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. As of the date of this report, there have been no material changes to the risk factors described in our Form 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes since April 27, 2013 in our market risk. For further information on market risk, refer to Item 7A in our 2013 Annual Report on Form 10-K filed June 26, 2013.

ITEM 4. CONTROLS AND PROCEDURES

Under the supervision and with the participation of our Company’s management, including our Company’s President and Chief Executive Officer (“CEO”) and its Chief Financial Officer (“CFO”), management evaluated the effectiveness of the design and operation of our Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) as of July 27, 2013. Based upon their evaluation of these disclosure controls and procedures, the CEO and CFO concluded that the disclosure controls and procedures were effective as of July 27, 2013.

There were no changes in our Company’s internal control over financial reporting (as defined in Rule 13a-15(f) or 15d-15(f) under the Exchange Act) that occurred during the quarter ended July 27, 2013 that have materially affected, or are reasonably likely to materially affect, our Company’s internal control over financial reporting.

Segment Reporting [Abstract]

SEGMENT REPORTING

NOTE 6 SEGMENT REPORTING

Patterson Companies, Inc. is comprised of three reportable segments: dental, veterinary, and rehabilitation supply. Our reportable business segments are strategic business units that offer similar products and services to different customer bases. The dental supply segment provides a virtually complete range of consumable dental products, clinical and laboratory equipment and value-added services to dentists, dental laboratories, institutions and other dental healthcare providers throughout North America. The veterinary supply segment provides consumable supplies, equipment, diagnostic products, biologicals (vaccines) and pharmaceuticals to companion-pet veterinary clinics throughout the United States. The rehabilitation supply segment provides a comprehensive range of distributed and self-manufactured rehabilitation medical supplies and assistive products to acute care hospitals, long-term care facilities, rehabilitation clinics, dealers and schools.

We evaluate segment performance based on operating income. The corporate office general and administrative expenses are included in the dental supply segment and consist of home office support costs in areas such as informational technology, finance, human resources and facilities. If these corporate expenses were allocated to the segments, the results would not be materially different as the dental segment would absorb a significant portion of these expenses. The costs to operate the distribution centers are allocated to the operating units based on the through-put of each unit.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

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.
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 as of July 27, 2013 is as follows:

			Quoted Prices in		Significant Other		Significant
			Active Markets		Observable Inputs		Unobservable Inputs
	Total		(Level 1)		(Level 2)		(Level 3)
Assets:
Cash equivalents	$	389,690	$	389,690	$	—	$	—

Our hierarchy for assets and liabilities measured at fair value on a recurring basis as of April 27, 2013 is as follows:

			Quoted Prices in		Significant Other		Significant
			Active Markets		Observable Inputs		Unobservable Inputs

Liabilities:
Derivative instruments	$	509	$	—	$	509	$	—

Cash equivalents – We value cash equivalents at their current market rates. The carrying value of cash equivalents, including government securities and money market funds, is recorded at fair value and maturities are less than three months.

Derivative instruments – Patterson’s derivative instruments consist of interest rate contracts. 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 periods ended July 27, 2013 or July 28, 2012.

The carrying amounts of receivables, net of allowances, accounts payable, and certain accrued and other current liabilities approximated fair value at July 27, 2013 and July 28, 2012.

EMPLOYEE STOCK OWNERSHIP PLAN (ESOP)

NOTE 7 EMPLOYEE STOCK OWNERSHIP PLAN (ESOP)

During 1990, our Board of Directors adopted a leveraged ESOP. In fiscal 2002 and 2006, under the provisions of the plan and related financing arrangements, Patterson loaned the ESOP $12,612 (the “2002 note”) and $105,000 (the “2006 note”), respectively. The contribution from the ESOP to employees is determined annually by the Board of Directors. Shares of stock acquired by the plan are allocated to each participant who has completed 1,000 hours of service during the plan year. These shares are accounted for under ASC 718-40, Share-based Payments – Employee Stock Ownership Plans, and are not considered outstanding for computation of earnings per share until the shares are committed for release to the participants. We recognize expense based on the current fair value of the shares released to participants. As of July 27, 2013, a total of 3,018,992 of unallocated shares were held by the ESOP. The ESOP expense recognized during the three months ended July 27, 2013 and July 28, 2012 was $5,700 for both quarters.

CUSTOMER FINANCING

CUSTOMER FINANCING

NOTE 5 CUSTOMER FINANCING

As a convenience to our customers, we offer several different financing alternatives including both our Company-sponsored program and a third party 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 our sponsored program, equipment purchased by customers with strong credit may be financed up to a maximum of $400 for any one customer. We generally sell the customers’ financing contracts to outside financial institutions in the normal course of our business. Patterson currently has two arrangements under which we sell these contracts.

Patterson operated under an agreement to sell a portion of our equipment finance contracts to commercial paper conduits with The Bank of Tokyo-Mitsubishi UFJ, Ltd. serving as the agent. We utilize a special purpose entity (“SPE”), PDC Funding, a consolidated, wholly owned subsidiary to fulfill a requirement of participating in the commercial paper conduit. We receive approximately 85% of the principal amounts of the contracts upon sale. The remaining 15% of the proceeds are held by the conduit as security against the eventual performance of the portfolio. The capacity under the agreement at July 27, 2013 was $500,000.

Patterson also maintains an agreement with Fifth Third Bank whereby the bank purchases customers’ financing contracts. Patterson has established another SPE, PDC Funding II, as a consolidated, wholly owned subsidiary, which sells financing contracts to the bank. We receive approximately 81% of the principal amounts of the contracts upon sale. The remaining 19% of the proceeds is held by the conduit as security against the eventual performance of the portfolio. The capacity under the agreement at July 27, 2013 was $75,000.

The portion of the purchase price for the receivables held by the conduits is a deferred purchase price receivable, which is paid to the SPE as payments on the receivables are collected from customers. The deferred purchase price receivable represents a beneficial interest in the transferred financial assets and is recognized at fair value as part of the sale transaction. The Company values the deferred purchase price receivable based on a discounted cash flow analysis using unobservable inputs (i.e. level 3 inputs), which include a forward yield curve, the estimated timing of payments and the credit quality of the underlying creditor. Significant increases in any of the significant unobservable inputs in isolation would not result in a materially lower fair value estimate. The interrelationship between these inputs is insignificant.

These financing arrangements are accounted for as a sale of assets under the provisions of ASC Topic No. 860, Transfers and Servicing. During the three months ended July 27, 2013 and July 28, 2012, we sold approximately $69,500, and $95,100, respectively, of contracts under these arrangements. Patterson retains servicing responsibilities under both agreements, for which we are paid a servicing fee. The servicing fees received by Patterson are considered adequate compensation for services rendered. Accordingly, no servicing asset or liability has been recorded. The agreements require us to maintain a minimum current ratio and maximum leverage ratio. Patterson was in compliance with the covenants at July 27, 2013.

Included in current receivables in the consolidated balance sheets are approximately $40,290, net of unearned income of $791, and $64,272, net of unearned income of $1,586, as of July 27, 2013 and April 27, 2013, respectively, of finance contracts not yet sold by Patterson. A total of $491,283 of finance contracts receivable sold under the agreements was outstanding at July 27, 2013. The deferred purchase price under the arrangements was approximately $72,493 and $72,328 as of July 27, 2013 and April 27, 2013, respectively. Since the internal financing program began in 1994, bad debt write-offs have amounted to less than one-percent of the loans originated.

Recently Issued Accounting Pronouncements

In July 2012, the FASB issued ASU No. 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment. Under this standard, entities testing long-lived intangible assets for impairment now have an option of performing a qualitative assessment to determine whether further impairment testing is necessary. If an entity determines, on the basis of qualitative factors, that the fair value of the indefinite-lived intangible asset is more-likely-than-not less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. For Patterson, this ASU was effective beginning April 28, 2013. The adoption of this standard did not have a material impact on Patterson’s consolidated results of operations or financial condition.

On August 16, 2013 Patterson Companies, Inc. completed the acquisition of all the outstanding stock of National Veterinary Services Limited (“NVS”) from Dechra Pharmaceuticals, PLC. NVS is the largest veterinary products distributor in the United Kingdom. Total cash consideration paid for NVS was £93,500 (approximately $146,000). £87,500 was paid at closing and an additional £6,000 was paid on August 21, 2013 due to higher working capital balances at NVS on the close date.

On August 22, 2013 the Company announced a plan to divest certain non-core product lines in its medical segment. As a result of the plan to dispose of these product lines, the Company expects to incur a pre-tax restructuring charge in the range of $15,000 to $17,000, or approximately $0.12 per diluted share. Approximately $14,000 to $15,000 of the restructuring charge will be non-cash losses on disposal of assets. The remainder of the restructuring charge will result in cash expenditures in connection with the closing of a facility.

DERIVATIVE FINANCIAL INSTRUMENTS

NOTE 3 DERIVATIVE FINANCIAL INSTRUMENTS

Patterson is a party to certain offsetting and identical interest rate cap agreements. These cap agreements are not designated for hedge accounting treatment and were entered into to fulfill certain covenants of a sale agreement between a commercial paper conduit managed by The Bank of Tokyo-Mitsubishi UFJ, Ltd. and PDC Funding. On November 30, 2012, this agreement was amended on terms consistent with the expiring agreement. The cap agreements provide a credit enhancement feature for the financing contracts sold by PDC Funding to the commercial paper conduit.

The cap agreements are cancelled and new agreements entered into periodically to maintain consistency with the dollar maximum of the sale agreements and the maturity of the underlying financing contracts. As of July 27, 2013, PDC Funding had purchased an interest rate cap from a bank with a notional amount of $500,000 and a maturity date of December 2019. Patterson Companies, Inc. sold an identical interest rate cap to the same bank.

Similar to the above agreements, PDC Funding II, and Patterson Companies, Inc. entered into offsetting and identical interest rate cap agreements with a notional amount of $75,000 in fiscal 2013. In August 2013, these agreements were terminated and replaced with offsetting and identical interest rate cap agreements. The notional amount increased to $100,000 and the new maturity date is January 2021.

In addition to the identical purchased and sold interest rate cap agreements described above, in May 2012 we entered into an interest rate swap agreement with a bank to economically hedge the interest rate risk associated with our finance contracts.

Our interest rate contracts 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.

The following table presents the fair value of our interest rate contracts on the consolidated balance sheets:

		July 27,		April 27,		July 28,
Derivative type	Classification	2013		2013		2012
Assets:
Interest rate contracts	Other noncurrent assets	$	1,153	$	486	$	229
