NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial statements and, therefore, do not include all information and disclosures of results of operations, financial position and changes in cash flow in conformity with accounting principles generally accepted in the United States for complete financial statements. Accordingly, such statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 previously filed with the Securities and Exchange Commission. In the opinion of management, such statements reflect all adjustments (which include only normal recurring adjustments) necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. Due to the seasonality of the Snowmobiles; Off-Road Vehicles (“ORV”), which includes all-terrain vehicles (“ATV”) and side-by-side vehicles; On-Road Vehicles, which is comprised of motorcycles and electric vehicles; and Parts, Garments and Accessories (“PG&A”) businesses, and to certain changes in production and shipping cycles, results of such periods are not necessarily indicative of the results to be expected for the complete year.

Product Warranties

Polaris provides a limited warranty for ORVs for a period of six months and for a period of one year for its snowmobiles and motorcycles. Polaris may provide longer warranties related to certain promotional programs, as well as longer warranties in certain geographical markets as determined by local regulations and market conditions. Polaris’ standard warranties require the Company or its dealers to repair or replace defective product during such warranty period at no cost to the consumer. The warranty reserve is established at the time of sale to the dealer or distributor based on management’s best estimate using historical rates and trends. Adjustments to the warranty reserve are made from time to time as actual claims become known in order to properly estimate the amounts necessary to settle future and existing claims on products sold as of the balance sheet date. Factors that could have an impact on the warranty accrual in any given period include the following: improved manufacturing quality, shifts in product mix, changes in warranty coverage periods, snowfall and its impact on snowmobile usage, product recalls and any significant changes in sales volume. The activity in Polaris’ accrued warranty reserve for the periods presented is as follows (in thousands):

	For the Three  Months Ended June 30,						For the Six Months Ended June 30,
	2011			2010			2011			2010
Accrued warranty reserve, beginning	$	31,029		$	22,344		$	32,651		$	25,520
Additions to warranty reserve through acquisitions		2,018			—			2,018			—
Additions charged to expense		7,592			10,930			16,517			20,878
Warranty claims paid		(8,777	)		(8,613	)		(19,324	)		(21,737	)
Accrued warranty reserve, ending	$	31,862		$	24,661		$	31,862		$	24,661

NOTE 2. Share-Based Employee Compensation

The amount of compensation cost for share-based awards to be recognized during a period is based on the portion of the awards that are ultimately expected to vest. The Company estimates option forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company analyzes historical data to estimate pre-vesting forfeitures and records share compensation expense for those awards expected to vest.

Total share-based compensation expenses are as follows (in thousands):

	For the Three Months Ended June 30,				For the Six Months  Ended June 30,
	2011		2010		2011		2010
Option plan	$	2,448	$	1,285	$	4,721	$	2,569
Other share-based awards		27,232		10,859		40,327		17,450
Total share-based compensation before tax		29,680		12,144		45,048		20,019
Tax benefit		11,229		4,823		17,095		7,859
Total share-based compensation expense included in net income	$	18,451	$	7,321	$	27,953	$	12,160

6

In addition to the above share-based compensation expense, Polaris sponsors a qualified non-leveraged employee stock ownership plan (“ESOP”). Shares allocated to eligible participants’ accounts vest at various percentage rates based on years of service and require no cash payments from the recipient.

At June 30, 2011 there was $25,159,000 of total unrecognized share-based compensation expense related to unvested share-based awards. Unrecognized share-based compensation expense is expected to be recognized over a weighted-average period of 1.8 years. Included in unrecognized share-based compensation is $19,009,000 related to stock options and $6,150,000 related to restricted stock.

NOTE 3. Inventories

Inventories are stated at the lower of cost (first-in, first-out method) or market. The major components of inventories are as follows (in thousands):

	June 30, 2011			December 31, 2010
Raw materials and purchased components	$	54,651		$	35,580
Service parts, garments and accessories		72,679			60,813
Finished goods		175,342			155,744
Less: reserves		(16,535	)		(16,210	)
Inventories	$	286,137		$	235,927

NOTE 4. Financing Agreement

Polaris is a party to an unsecured bank agreement comprised of a $250,000,000 revolving loan facility for working capital needs. As part of the bank agreement, the Company had a $200,000,000 term loan outstanding at December 31, 2010 and March 31, 2011, which was paid off in its entirety in May 2011 with the issuance of the Senior Notes described below and $100,000,000 of cash on hand. In anticipation of the Senior Notes being issued in May 2011, the Company classified $100,000,000 of the $200,000,000 term loan outstanding as of December 31, 2010 and March 31, 2011 as a long-term liability in each of the respective consolidated balance sheets. The bank agreement expires on December 2, 2011. There were no borrowings under the revolving loan facility at June 30, 2011.

In December 2010 the Company entered into a Master Note Purchase Agreement to issue $25,000,000 of 3.81 percent unsecured Senior Notes due May 2018 and $75,000,000 of 4.60 percent unsecured Senior Notes due May 2021 (collectively, “The Senior Notes”). The Senior Notes were issued in May 2011.

Polaris previously entered into various interest rate swap agreements to manage exposures to fluctuations in interest rates under the term loan by fixing the LIBOR interest rate. Each of these interest rate swaps were designated as and met the criteria of cash flow hedges. The swap agreements expired in April 2011.

The Company entered into and settled an interest rate lock contract in November 2010 in connection with the Master Note Purchase Agreement. The interest rate lock settlement resulted in a $251,000 gain, net of deferred taxes of $149,000, which is being amortized into income over the life of the related debt.

NOTE 5. Financial Services Arrangements

In 1996, a wholly-owned subsidiary of Polaris entered into a partnership agreement with an entity that is now a subsidiary of GE Commercial Distribution Finance Corporation (“GECDF”) to form Polaris Acceptance. Polaris’ subsidiary has a 50 percent equity interest in Polaris Acceptance. In November 2006, Polaris Acceptance sold a majority of its receivable portfolio (the “Securitized Receivables”) to a securitization facility (“Securitization Facility”) arranged by General Electric Capital Corporation, a GECDF affiliate, and the partnership agreement was amended to provide that Polaris Acceptance would continue to sell portions of its receivable portfolio to the Securitization Facility from time to time on an ongoing basis. The sale of receivables from Polaris Acceptance to the Securitization Facility is accounted for in Polaris Acceptance’s financial statements as a “true-sale” under ASC Topic 860. Substantially all of Polaris’ U.S. sales are financed through Polaris Acceptance and the Securitization Facility whereby Polaris receives payment within a few days of shipment of the product. The net amount financed for dealers under this arrangement at June 30, 2011, including both the portfolio balance in Polaris Acceptance and the Securitized Receivables, was $454,782,000 which includes $171,213,000 in the Polaris Acceptance portfolio and $283,569,000 of Securitized Receivables. Polaris has agreed to repurchase products repossessed by Polaris Acceptance or the Securitization Facility up to an annual maximum of 15 percent of the aggregate average month-end balances outstanding during the prior calendar year with respect to receivables retained by Polaris Acceptance and Securitized Receivables. For calendar year 2011, the potential 15 percent aggregate repurchase obligation is approximately $74,073,000. Polaris’ financial exposure under this arrangement is limited to the difference between the amount paid to the finance company for repurchases and the amount received on the resale of the repossessed product. No material losses have been incurred under this agreement. Polaris’ total investment in Polaris Acceptance at June 30, 2011 of $35,567,000 is accounted for under the equity method, and is recorded as Investments in finance affiliate in the accompanying consolidated balance sheets. Polaris’ allocable share of the income of Polaris Acceptance and the Securitization Facility has been included as a component of Income from financial services in the accompanying consolidated statements of income. During February 2011, Polaris and GECDF amended and restated its Polaris Acceptance partnership agreement through February 2017 with similar terms to the previous agreement.

In August 2005, a wholly-owned subsidiary of Polaris entered into a multi-year contract with HSBC Bank Nevada, National Association (“HSBC”), formerly known as Household Bank (SB), N.A., under which HSBC manages the Polaris private label credit card program under the StarCard label, currently providing revolving retail credit for Polaris products. During the 2010 second quarter, Polaris and HSBC extended the agreement to October 2013. Polaris’ income generated from the HSBC agreement has been included as a component of Income from financial services in the accompanying consolidated statements of income.

In April 2006, a wholly-owned subsidiary of Polaris entered into a multi-year contract with GE Money Bank (“GE Bank”) under which GE Bank makes available closed-end installment consumer and commercial credit to customers of Polaris dealers for both Polaris and non-Polaris products. In November 2010, the Company extended its installment credit agreement to March 2016 under which GE Bank provides installment credit lending for motorcycles. Polaris’ income generated from the GE Bank agreement has been included as a component of Income from financial services in the accompanying consolidated statements of income. In January 2009, a wholly-owned subsidiary of Polaris entered into a multi-year contract with Sheffield Financial (“Sheffield”) pursuant to which Sheffield agreed to make available closed-end installment consumer and commercial credit to customers of Polaris dealers for Polaris products. In October 2010, Polaris extended its installment credit agreement to February 2016 under which Sheffield provides installment credit lending for ORVs, Snowmobiles and certain other Polaris products. Polaris’ income generated from the Sheffield agreement has been included as a component of Income from financial services in the accompanying consolidated statements of income.

Polaris also provides extended service contracts to consumers and certain insurance contracts to dealers and consumers through various third-party suppliers. Polaris does not retain any warranty, insurance or financial risk in any of these arrangements. Polaris’ service fee income generated from these arrangements has been included as a component of Income from financial services in the accompanying consolidated statements of income.

NOTE 6. Investment in Manufacturing Affiliates

The caption Investments in manufacturing affiliates in the consolidated balance sheets represents Polaris’ 40 percent equity ownership investment in Robin Manufacturing, U.S.A. (“Robin”), which builds engines in the United States for recreational and industrial products. Fuji and Polaris have agreed to close the Robin facility by third quarter 2011 as the production volume of engines made at the facility has declined significantly in recent years. In the third quarter of 2010, the Company sold its remaining equity investment in the Austrian motorcycle company, KTM Power Sports AG (“KTM”) which manufactures off-road and on-road motorcycles. Prior to the sale of the KTM investment, the Company owned less than 5 percent of KTM’s outstanding shares. The KTM investment, prior to the sale, had been classified as available for sale securities under ASC Topic 320.

NOTE 8. Shareholders’ Equity

During the first six months of 2011, Polaris paid $32,856,000 to repurchase and retire approximately 419,000 shares of its common stock related primarily to open market share repurchases. As of June 30, 2011, the Company has authorization from its Board of Directors to repurchase up to an additional 2,700,000 shares of Polaris stock. The repurchase of any or all such shares authorized for repurchase will be governed by applicable SEC rules and dependent on management’s assessment of market conditions. Polaris paid a regular cash dividend of $0.45 per share on May 16, 2011 to holders of record on May 2, 2011. On July 20, 2011, the Polaris Board of Directors declared a regular cash dividend of $0.45 per share payable on or about August 15, 2011 to holders of record of such shares at the close of business on August 1, 2011.

Net Income per Share

Basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during each period, including shares earned under the nonqualified deferred compensation plan (“Director Plan”), the ESOP and deferred stock units under the Omnibus Incentive Plan (“Omnibus Plan”). Diluted earnings per share is computed under the treasury stock method and is calculated to compute the dilutive effect of outstanding stock options issued under the 1995 Stock Option Plan and the 2003 Non-Employee Director Stock Option Plan (collectively, the “Option Plans”) and the Omnibus Plan and certain shares issued under the Restricted Stock Plan (“Restricted Plan”). A reconciliation of these amounts is as follows (in thousands):

	For the Three  Months Ended June 30,				For the Six Months Ended June 30,
	2011		2010		2011		2010
Weighted average number of common shares outstanding		34,174		32,956		34,101		32,851
Director plan and deferred stock units		170		161		167		168
ESOP		61		138		69		143
Common shares outstanding — basic		34,405		33,255		34,337		33,162
Dilutive effect of Restricted Plan and Omnibus Plan		94		66		86		62
Dilutive effect of Option Plans and Omnibus Plan		1,108		927		1,046		775
Common and potential common shares outstanding — diluted		35,607		34,248		35,469		33,999

During the second quarter and year-to-date periods ending June 30, 2011, the number of options that could potentially dilute earnings per share on a fully diluted basis that were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive were approximately 30,000 and 250,000, respectively, compared to 291,000 and 2,701,000, respectively, for the same periods in 2010.

Comprehensive Income

NOTE 9. Commitments and Contingencies

Polaris is subject to product liability claims in the normal course of business. Polaris is currently self-insured for all product liability claims. The estimated costs resulting from any losses are charged to Operating expenses when it is probable a loss has been incurred and the amount of the loss is reasonably determinable. The Company utilizes historical trends and actuarial analysis tools to assist in determining the appropriate loss reserve levels.

10

Polaris is a defendant in lawsuits and subject to claims arising in the normal course of business. In the opinion of management, it is not probable that any legal proceedings pending against or involving Polaris will have a material adverse effect on Polaris’ financial position or results of operations.

NOTE 10. Derivative Instruments and Hedging Activities

The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by using derivative instruments are foreign currency risk, interest rate risk and commodity price fluctuations. Derivative contracts on various currencies are entered into in order to manage foreign currency exposures associated with certain product sourcing activities and intercompany sales. Interest rate swaps are entered into in order to manage interest rate risk associated with the Company’s variable-rate borrowings. Commodity hedging contracts are entered into in order to manage fluctuating market prices of certain purchased commodities and raw materials that are integrated into the Company’s end products.

The Company’s foreign currency management objective is to mitigate the potential impact of currency fluctuations on the value of its U.S. dollar cash flows and to reduce the variability of certain cash flows at the subsidiary level. The Company actively manages certain forecasted foreign currency exposures and uses a centralized currency management operation to take advantage of potential opportunities to naturally offset foreign currency exposures against each other. The decision of whether and when to execute derivative instruments, along with the duration of the instrument, can vary from period to period depending on market conditions, the relative costs of the instruments and capacity to hedge. The duration is linked to the timing of the underlying exposure, with the connection between the two being regularly monitored. Polaris does not use any financial contracts for trading purposes. At June 30, 2011, Polaris had the following open contracts (in thousands):

Foreign Currency	Notional Amounts (in US Dollars)		Unrealized Loss
Australian Dollar	$	9,599	$	(625	)
Canadian Dollar		262,653		(6,526	)
Swedish Krona		5,958		(233	)
Total	$	278,210	$	(7,384	)

These contracts, with maturities through December 2012, met the criteria for cash flow hedges and the unrealized gains or losses, after tax, are recorded as a component of Accumulated other comprehensive income in Shareholders’ Equity.

Polaris has entered into derivative contracts to hedge a portion of the exposure related to diesel fuel and aluminum for 2011. These diesel fuel and aluminum derivative contracts did not meet the criteria for hedge accounting.

The table below summarizes the carrying values of derivative instruments as of June 30, 2011 and 2010 (in thousands):

(1) Assets are included in Prepaid expenses and other and liabilities are included in Other accrued expenses on the accompanying consolidated balance sheet.

For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of Accumulated other comprehensive income and reclassified into the income statement in the same period or periods during which the hedged transaction affects the income statement. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in the current income statement. The table below provides data about the amount of gains and losses, net of tax, related to derivative instruments designated as cash flow hedges included in Accumulated other comprehensive income for the three months ended June 30 (in thousands):

Derivatives in Cash Flow Hedging Relationships	For the Three  Months Ended June 30,					For the Six Months Ended June 30,
	2011			2010		2011			2010

The table below provides data about the amount of gains and losses, net of tax, reclassified from Accumulated other comprehensive income into income (loss) on derivative instruments designated as hedging instruments for the three and six month periods ended June 30, 2011 and 2010 (in thousands):

Derivatives in Cash Flow Hedging Relationships	Location of Gain (Loss) Reclassified from Accumulated OCI Into Income	For the Three  Months Ended June 30,						For the Six Months Ended June 30,

Foreign currency contracts	Cost of Sales		—			49			—			24
Total		$	1,606		$	381		$	1,870		$	(7	)

The net amount of the existing gains or losses at June 30, 2011 that is expected to be reclassified into the income statement within the next 12 months is expected to not be material. The ineffective portion of foreign currency contracts was not material for the three and six months ended June 30, 2011.

The Company recognized a loss of 2,000 and a gain of $661,000 in cost of sales on commodity contracts not designated as hedging instruments for the three and six month periods ended June 30, 2011, respectively, versus losses of $2,544,000 and $2,438,000 for the three and six month periods ended June 30, 2010.

NOTE 11. Fair Value Measurements

ASC Topic 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This topic also establishes a fair value hierarchy which requires classification based on observable and unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company utilizes the market approach to measure fair value for its non-qualified deferred compensation assets and the income approach for the interest rate swap agreements, foreign currency contracts and commodity contracts. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities and for the income approach the Company uses significant other observable inputs such as quotations from third parties, to value its derivative instruments used to hedge interest rate volatility and foreign currency and commodity transactions (see Note 10 for additional details). Assets and liabilities measured at fair value on a recurring basis are summarized below (in thousands):

	Fair Value Measurements as of June 30, 2011

NOTE 12. Manufacturing Realignment

In May 2010, the Company announced that it was realigning its manufacturing operations. The realignment will consolidate operations into existing operations in Roseau, MN and Spirit Lake, IA as well as establish a new facility in Monterrey, Mexico. The realignment will lead to the sale or closure of a portion of the Osceola, WI manufacturing operations by 2012. Due to the increased demand for Polaris product, in April 2011, the Company reconsidered its decision regarding the Osceola operations and announced that it would maintain its snowmobile and motorcycle engine assembly in Osceola, WI. The Company expects to record transition charges, including both exit costs and startup costs, over the 2010 to 2012 periods. The exit costs pertaining to the manufacturing realignment are expected to total approximately $10,000,000 over that time period. The exit costs are classified within cost of sales in the consolidated statements of income. A summary of these exit costs follows (in thousands):

	Total Amount Expected to  be Incurred		Amount Incurred during the Three Months Ended June 30, 2011			Cumulative Amounts Incurred through June 30, 2011

Note 13. Subsequent Event

In July 2011, Polaris announced that its Board of Directors has approved a two-for-one split of the Company’s outstanding shares of Common stock to be effected in the form of a one-hundred percent stock dividend. On September 12, 2011, Polaris shareholders will receive one additional share of Common stock for each share of record they hold at the close of business on September 2, 2011. Upon completion of the stock split, Polaris will have approximately 69,000,000 shares of Common Stock outstanding. In connection with the stock split, the Board of Directors approved a corresponding increase in the common shares authorized to be issued from 80,000,000 shares to 160,000,000 shares. The shares and per share amounts presented herein have not been adjusted to reflect the impact of the stock split.

Item 2

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

The following discussion pertains to the results of operations and financial position of Polaris Industries Inc., a Minnesota corporation, for the quarter and six months ended June 30, 2011. The terms “Polaris,” the “Company,” “we,” “us,” and “our” as used herein refer to the business and operations of Polaris Industries Inc., its subsidiaries and its predecessors, which began doing business in the early 1950’s. Due to the seasonality of the Snowmobiles; Off-Road Vehicles (“ORV”), which includes all-terrain vehicles (“ATV”) and side-by-side vehicles; On-Road Vehicles, which is comprised of motorcycles and electric vehicles; and Parts, Garments and Accessories (“PG&A”) businesses, and to certain changes in production and shipping cycles, results of such periods are not necessarily indicative of the results to be expected for the complete year.

For the second quarter ended June 30, 2011, we reported net income of $48.7 million, or $1.37 per diluted share, driven by a 300 basis point increase in our gross profit margin percentage. By comparison, 2010 second quarter net income was $25.6 million, or $0.75 per diluted share. Sales for the second quarter 2011 totaled $607.9 million, an increase of 41 percent from last year’s second quarter sales of $430.9 million. The second quarter sales and earnings growth was driven by strong retail sales demand for our products and continued market share gains. Our unit retail sales to consumers in North America grew 19 percent during the second quarter of 2011 compared to the second quarter of 2010, with strong demand experienced for our off-road vehicles and Victory motorcycles. We achieved strong market share improvements in ORV and motorcycles in North America as the retail sales performance was notably stronger than overall industry retail sales. Our sales to customers outside of North America grew 35 percent in the second quarter of 2011. All geographies experienced sales growth during the 2011 second quarter. As a result of continuous improvement efforts directed at cost reduction and profitability enhancements, we generated significant margin expansion. In the second quarter 2011, the gross profit margin percentage improved by 300 basis points. The increase in gross margin contributed to an 8.0 percent net income margin for the 2011 second quarter, a 210 basis point increase from the second quarter last year. In April 2011, we acquired Indian Motorcycle Company, the maker of America’s first motorcycle and Global Electric Motorcars LLC (GEM), a manufacturer of premium electric-powered vehicles. These transactions will complement and enhance our On-Road Vehicles product portfolio and afford us the opportunity to bring our world-class engineering, manufacturing, and distribution capabilities to two recognizable brands in their respective markets. Our strong balance sheet, with $262.2 million in cash on hand and only $100.0 million in debt at June 30, 2011, gives us the strength and flexibility to remain aggressive in identifying opportunities to accelerate growth. During the 2011 second quarter, we issued $100.0 million of senior notes and used $100.0 million of cash on hand to retire the $200.0 million term loan.

In July 2011, Polaris’ Board of Directors announced they had approved a two-for-one split of the Company’s outstanding shares of Common stock to be effected in the form of a one-hundred percent stock dividend. On September 12, 2011, Polaris shareholders will receive one additional share of Common Stock for each share of record they hold at the close of business on September 2, 2011. Upon completion of the stock split, Polaris will have approximately 69.0 million shares of Common Stock outstanding. In connection with the stock split, the Board of Directors approved a corresponding increase in the common shares authorized to be issued from 80.0 million shares to 160.0 million shares. The shares and per share amounts presented in our discussion and analysis of Polaris’ financial condition and results of operations have not been adjusted to reflect the impact of the stock split.

Results of Operations

Sales: Sales were $607.9 million in the second quarter 2011, a 41 percent increase from $430.9 million in sales for the same period in 2010. Year-to-date, sales were $1,145.1 million, a 44 percent increase from $792.6 million for the year-to-date period last year.

The following table is an analysis of the percentage change in our sales for the 2011 and 2010 second quarter and year-to-date periods when compared to the same prior periods:

	Percent Change in Total Company Sales Compared to Corresponding Periods of the Prior Year Periods
	Three Months Ended			Six Months Ended
	June 30, 2011			June 30, 2011
Volume		28	%		35	%
Product mix and price		10	%		7	%
Currency		3	%		2	%
Total		41	%		44	%

15

Volume for the 2011 second quarter and year-to-date periods increased 28 percent and 35 percent, respectively, compared to the same periods in 2010 as we shipped more off-road vehicles, Victory motorcycles, and snowmobiles to dealers given the strong consumer retail demand for our products both in North America and internationally and lower year over year dealer inventory levels. Product mix and price increased for the 2011 second quarter and year-to-date compared to the same periods in 2010 primarily due to the positive benefit of a greater number of higher priced side-by-side vehicles sold to dealers relative to our other businesses and select selling price increases on several of the model year 2011 products. Favorable movements in currency rates for the 2011 second quarter and year-to-date periods increased sales three percent and two percent, respectively, compared to the same periods in 2010 due to the change in the currency rates and their effect on our Canadian and other foreign subsidiaries when translated to U.S. dollars.

Our sales by product line are as follows:

	Three Months Ended June 30,													Six Months Ended June 30,
(in millions)	2011		Percent of Total Sales			2010		Percent of Total Sales			Dollar Percent Change			2011		Percent of Total Sales			2010		Percent of Total Sales			Dollar Percent Change

ORV sales of $482.3 million in the 2011 second quarter, which includes both ATV and side-by-side vehicle sales, increased 41 percent from the second quarter 2010. Year-to-date 2011 ORV sales increased 47 percent from the same period in 2010 to a total of $870.3 million. This increase for the quarter and year-to-date periods reflects significant North American market share gains for both ATVs and side-by-side vehicles and increased sales in our adjacency businesses of military and Bobcat. North American consumer ORV unit retail sales increased 18 percent for the 2011 second quarter from the second quarter last year, with side-by-side vehicle unit retail sales increasing significantly and ATV unit retail sales up slightly. North American dealer inventories of ORVs for the 2011 second quarter were up slightly from the second quarter of 2010 due to higher side-by-side inventory as retail sales continued very strong. Sales of ORVs outside of North America increased 35 percent in the second quarter 2011 when compared to the second quarter 2010, due to positive mix benefit from increased sales of higher priced side-by-side vehicles, and positive currency benefit from the weaker US dollar. For the 2011 second quarter, the average ORV per unit sales price increased 11 percent over last year’s comparable period primarily as a result of the increased sales of the higher priced side-by-side vehicle models and select selling price increases on several of the model year 2011 products.

Snowmobile sales totaled $6.8 million for the 2011 second quarter compared to $2.0 million for the second quarter of 2010. For the year-to-date period, snowmobile sales were $15.8 million, a 110 percent increase compared to the same period last year. Second quarter sales are historically a seasonally low quarter for snowmobile shipments, as deliveries to dealers ramp up in the second half of the calendar year before the snowmobile retail selling season begins in earnest. Sales increased primarily due to an increase in shipments to customers outside of the United States in the 2011 second quarter compared to the second quarter last year. The average snowmobile per unit sales price for the second quarter 2011 increased significantly compared to the same period last year primarily due to favorable foreign currency rate movements in the second quarter 2011 compared to the second quarter 2010 and timing of shipments of certain higher priced models in the second quarter 2011 compared to 2010.

Sales of the On-Road Vehicles division, which primarily consists of Victory motorcycles, increased 99 percent to $30.9 million during the second quarter of 2011 when compared to the same period in 2010. Year-to-date 2011 On-Road Vehicle sales increased 86 percent compared to the comparable period of 2010, to a total of $75.8 million. Polaris sales of On-Road Vehicles to customers outside of North America increased 34 percent during the 2011 second quarter compared to the prior year’s second quarter. The North American heavyweight cruiser and touring motorcycle industry retail sales were up slightly during the 2011 second quarter compared to the prior year’s second quarter with Victory unit retail sales in North America up significantly during the 2011 second quarter. North American dealer inventory of Victory motorcycles for the 2011 second quarter remained approximately equal to comparable 2010 levels. The average per unit sales price for the On-Road Vehicles division in the 2011 second quarter increased 18 percent compared to the second quarter 2010, primarily due to shipments of higher priced touring motorcycles during the 2011 second quarter.

16

PG&A sales increased 23 percent during the second quarter 2011 compared to the same period in 2010 with PG&A sales increasing across all businesses and product lines. Year-to-date PG&A sales increased 21 percent compared the same period in 2010.

Net sales in the United States for the second quarter of 2011 increased 40 percent compared to the second quarter of 2010. Net sales in the United States during the six months ended June 30, 2011 increased 47 percent compared to the same period in 2010. An increase in shipments of ORV and On-Road Vehicles and market share gains accounted for the increase for the second quarter and year-to-date periods. The United States represented 69 percent of total Company sales in the 2011 second quarter and year-to-date period compared to 70 percent and 68 percent of total Company sales for the 2010 second quarter and year-to-date periods, respectively.

Canada:

Canadian sales increased 60 percent for the 2011 second quarter compared to the same period in 2010. Year-to-date, sales in Canada increased 59 percent compared to the same period last year. Favorable currency rate movements accounted for nine percent of the increase in sales for both the 2011 second quarter and year-to-date periods compared to the same periods in 2010. Increased volume was the primary contributor for the remainder of the increase in sales for the 2011 second quarter and year-to-date periods. Canada represented 14 percent of total Company sales for both the 2011 second quarter and year-to-date periods compared to 12 percent and 13 percent of total Company sales for the 2010 second quarter and year-to-date periods, respectively.

Other Foreign Countries:

Sales in other foreign countries, primarily in Europe, increased 35 percent for the 2011 second quarter compared to the same period in 2010. Year-to-date, sales in other foreign countries increased 28 percent compared to the same period last year. Favorable currency rate movements accounted for 11 percent and seven percent of the increase in sales for the 2011 second quarter and year-to-date periods, respectively, compared to the same periods in 2010. The remainder of the increase in the second quarter 2011 was primarily driven by volume increases in ORV and Victory motorcycles resulting from higher retail sales. Other foreign countries represented 17 percent of total Company sales for both of the 2011 second quarter and year-to-date periods compared to 18 percent and 19 percent of total Company sales for the second quarter and year-to-date periods in 2010, respectively.

Percentage of Sales		70.8	%					73.8	%					-300 basis points			71.2	%					73.8	%					-260 basis points

For the 2011 second quarter and year-to-date periods, cost of sales increased 35 percent and 40 percent to $430.3 million and $815.7 million, respectively, compared to $317.8 million and $584.6 million, respectively, in 2010. The increase in cost of sales for the 2011 second quarter and year-to-date periods resulted primarily from the effect of increases in volume on purchased materials and labor costs, and higher commodity costs, offset by lower warranty costs.

Gross Profit:

The following table reflects the Company’s gross profits in dollars and as a percentage of sales for the second quarter and year-to-date periods:

	Three Months Ended June 30,									Six Months Ended June 30,
($ in millions)	2011			2010			Change			2011			2010			Change
Gross profit dollars	$	177.6		$	113.1			57	%	$	329.4		$	208.0			58	%
Percentage of Sales		29.2	%		26.2	%		+300 basis points			28.8	%		26.2	%		+260 basis points

Gross profit, as a percentage of sales, was 29.2 percent and 28.8 percent for the 2011 second quarter and year-to-date periods, respectively, an increase of 300 basis points and 260 basis points from the same periods last year, respectively. Gross profit dollars increased 57 percent and 58 percent to $177.6 million and $329.4 million for the 2011 second quarter and year-to-date periods compared to the same periods in 2010, respectively. The increase in the gross profit dollars and margin percentage during the 2011 second quarter and year-to-date periods resulted primarily from continued product cost reduction efforts, favorable currency rates, lower warranty rates, and significant production volume increases partially offset by increasing commodity costs and an unfavorable product mix when compared to the same periods last year.

Operating expenses:

The following table reflects the Company’s operating expenses in dollars and as a percentage of sales for the second quarter and year-to-date periods:

	Three Months Ended June 30,									Six Months Ended June 30,
($ in millions)	2011			2010			Change			2011			2010			Change

Percentage of Sales		17.5	%		17.3	%		+20 basis points			16.9	%		17.9	%		-100 basis points

Operating expenses for the 2011 second quarter and year-to-date periods increased 43 percent and 37 percent to $106.2 million and $193.7 million, respectively, compared to $74.4 million and $141.6 million for the same periods in 2010. Operating expenses in absolute dollars for the 2011 second quarter and year-to-date periods increased primarily due to continued infrastructure investments being made in international and adjacent markets for future growth opportunities, and increased incentive compensation plan expenses due to the higher expected profitability and the current higher stock price in 2011. Operating expenses as a percentage of sales was 17.5 percent and 16.9 percent for the 2011 second quarter and year to date periods, respectively, compared to 17.3 percent and 17.9 percent for the same periods in 2010, respectively.

Income from financial services:

	Three Months Ended June 30,									Six Months Ended June 30,
($ in millions)	2011			2010			Change			2011			2010			Change
Income from financial services	$	5.5		$	4.2			30	%	$	10.8		$	8.5			27	%
Percentage of Sales		0.9	%		1.0	%		-10 basis points			0.9	%		1.1	%		-20 basis points

Income from financial services increased 31 percent to $5.5 million in the 2011 second quarter compared to $4.2 million in the 2010 second quarter. Income from financial services increased 27 percent to $10.8 million for the six months ended June 30, 2011 from $8.5 million for the same period of 2010. Further discussion can be found in the “Liquidity and Capital Resources” section below.

Interest expense:

Interest expense increased to $1.0 million and $1.5 million for the three and six months ended June 30, 2011, respectively, compared to $0.7 million and $1.4 million for the same periods of 2010 due to higher interest rates of the long-term senior notes issued in May 2011.

Noncash Impairment charge on securities available for sale

The noncash Impairment charge on securities available for sale recorded in the second quarter 2010 was $0.8 million. The securities available for sale relate to the Company’s KTM investment which had a fair value equal to the trading price of KTM shares on the Vienna stock exchange (19.00 Euros at June 30, 2010). The total fair value of these securities as of June 30, 2010 was $8.0 million, which was below the Company’s cost basis for this investment at that time. During the second quarter 2010, the Company determined that the decline in the fair value of the KTM shares was other than temporary and therefore recorded the unrealized non-cash impairment charge of $0.8 million in the income statement. In the third quarter of 2010, the Company sold its remaining equity investment in KTM.

Other expense/income, net:

Non-operating other expense/income was $1.6 million of expense in the second quarter of 2011 compared to $2.3 million of expense for the same period in 2010. Year-to-date non-operating other expense/income was $1.6 million of income compared to $2.5 million of expense for the same period in 2010. The change for the quarter and year-to-date periods was primarily due to foreign currency exchange rate movements and the resulting effects of foreign currency transactions related to the Company’s foreign subsidiaries.

Provision for income taxes:

The income tax provision for the second quarter 2011 was recorded at a rate of 34.4 percent of pretax income compared to 34.5 percent of pretax income for the second quarter 2010. Year-to-date the income tax provision for 2011 was recorded at a rate of 34.5 percent of pretax income compared to 35.3 percent of pretax income for the 2010 year-to-date period. The higher income tax rate for the 2010 year-to-date period over 2011 resulted from not providing for the federal research and development tax credit in the first half of 2010 because it had not been extended by the U.S. Congress as of June 30, 2010.

Reported Net Income:

	Three Months Ended June 30,							Six Months Ended June 30,
($ in millions except per share data)	2011		2010		Change			2011		2010		Change
Net Income	$	48.7	$	25.6		90	%	$	96.0	$	45.4		112	%
Diluted Net Income per share	$	1.37	$	0.75		83	%	$	2.71	$	1.34		102	%

Reported net income for the second quarter 2010 was $48.7 million, or $1.37 per diluted share, compared to $25.6 million or $0.75 per diluted share for the second quarter 2010. Year-to-date 2011 reported net income was $96.0 million, or $2.71 per diluted share, compared to $45.4 million or $1.34 per diluted share for the 2010 period. The increase for the 2011 second quarter and year-to-date periods is primarily due to higher sales volume and higher gross profit margin percentage generated by the Company in 2011.

Weighted Average Shares Outstanding:

The weighted average diluted shares outstanding for the second quarter ended June 30, 2011 of 35.6 million shares is four percent higher than the comparable period in 2010. For the 2011 year-to-date period, the weighted average diluted shares outstanding of 35.5 million shares is up four percent compared to the same period in 2010. The increase in both periods is due to share issuances under employee plans.

Cash Dividends:

Polaris paid a $0.45 per share dividend on May 16, 2011 to shareholders of record on May 2, 2011. On July 20, 2011, the Polaris Board of Directors declared a regular cash dividend of $0.45 per share (pre-split) payable on or about August 15, 2011 to holders of record of such shares at the close of business on August 1, 2011.

Liquidity and Capital Resources

Polaris’ primary sources of funds have been cash provided by operating activities and borrowings under its credit arrangements. Polaris’ primary uses of funds have been for repayments under the credit agreement, repurchase and retirement of common stock, capital investments, acquisitions, cash dividends to shareholders and new product development.

The following table summarizes the cash flows from operating, investing and financing activities for the six months ended June 30, 2011 and 2010 ($ in millions):

	For the Six Months Ended June 30,
	2011			2010			Change
Total cash provided by (used for):
Operating activities	$	61.8		$	57.0		$	4.8
Investing activities		(64.7	)		(11.7	)		(53.0	)
Financing activities		(130.6	)		(19.3	)		(111.3	)
Impact of currency translation on cash balances		1.7			—			1.7
Increase (decrease) in cash and cash equivalents	$	(131.8	)	$	26.0		$	(157.8	)

Operating activities:

Net cash provided by operating activities totaled $61.8 million for the six months ended June 30, 2011, an increase from $57.0 million net cash provided in the first six months of 2010. The $4.8 million increase in net cash provided by operating activities for the six months ended June 30, 2011 compared to the same period in 2010 is primarily due to a $50.6 million increase in net income offset by a net investment in working capital of $31.7 million primarily due to higher accounts receivable from the significant increase in sales volumes to international customers.

Investing activities:

Net cash used for investing activities was $64.7 million for the six months of 2011 compared to cash used of $11.7 million for the same period in 2010. The primary use of cash for the first six months of 2011 and 2010 was the investment of $40.6 million and $20.9 million, respectively, for the purchase of property and equipment, including new product development tooling. In addition, we acquired Indian Motorcycle Company and GEM totaling $28.0 million during the six months ended June 30, 2011.

Financing activities:

Net cash used for financing activities was $130.6 million for the first six months of 2011 compared to cash used of $19.3 million for financing activities in the same period in 2010. In May 2011, we paid off the $200.0 million term loan with cash received from the issuance of $100.0 million of senior notes discussed below and $100.0 million of cash on hand. The Company previously entered into interest rate swap agreements to manage exposures to fluctuations in interest rates under the term loan by fixing the LIBOR interest rate. Each of these interest rate swaps were designated as and met the criteria of cash flow hedges. All swaps expired in April 2011. We paid cash dividends of $30.7 million and $26.3 million in the six months ended June 30, 2011 and 2010, respectively. Common stock repurchased during the first six months of 2011 and 2010 totaled $32.9 million and $27.4 million, respectively. Proceeds from the issuance of stock under employee plans were $23.1 million and $30.0 million for the six months ended June 30, 2011 and 2010, respectively.

The seasonality of production and shipments causes working capital requirements to fluctuate during the year. Polaris is party to an unsecured variable interest rate bank lending agreement that matures on December 2, 2011, comprised of a $250 million revolving loan facility for working capital needs. There were no borrowing under the revolving loan at June 30, 2011.

In December 2010, the Company entered into a Master Note Purchase Agreement to issue $25.0 million of 3.81 percent unsecured Senior Notes due May 2018 and $75.0 million of 4.60 percent unsecured Senior Notes due May 2021. The Senior Notes were issued in May 2011. Our debt to total capital ratio was 18 percent and 45 percent at June 30, 2011 and 2010, respectively.

20

Polaris entered into and settled an interest rate lock contract in November 2010 in connection with the Master Note Purchase Agreement. The interest rate lock settlement resulted in a $0.3 million gain, net of deferred taxes of $0.1 million, which is being amortized into income over the life of the related debt.

Additionally, at June 30, 2011, Polaris had letters of credit outstanding of $9.8 million related to purchase obligations for raw materials.

The Polaris Board of Directors has authorized the cumulative repurchase of up to 37.5 million shares of the Company’s common stock. Of that total, approximately 34.8 million shares have been repurchased cumulatively from 1996 through June 30, 2011. Polaris repurchased 0.4 million shares of Polaris stock for $32.9 million during the first six months of 2011 which increased reported earnings per share by approximately one cent.

The Company has authorization from its Board of Directors to repurchase up to an additional 2.7 million shares of Polaris stock as of June 30, 2011; however, the Company expects to take a prudent and conservative approach to the open market stock repurchase activity for the balance of 2011. The repurchase of any or all such shares authorized remaining for repurchase will be governed by applicable SEC rules.

Management believes that existing cash balances, and cash flow to be generated from operating activities and available borrowing capacity under the line of credit arrangement will be sufficient to fund operations, regular dividends, share repurchases, acquisitions, and capital requirements for the foreseeable future. At this time, management is not aware of any adverse factors that would have a material impact on cash flow.

In 1996, a wholly owned subsidiary of Polaris entered into a partnership agreement with an entity that is now a subsidiary of GE Commercial Distribution Finance Corporation (“GECDF”) to form Polaris Acceptance. Polaris Acceptance provides floor plan financing to Polaris’ dealers in the United States. Polaris’ subsidiary has a 50 percent equity interest in Polaris Acceptance. In November 2006, Polaris Acceptance sold a majority of its receivable portfolio (the “Securitized Receivables”) to a securitization facility (“Securitization Facility”) arranged by General Electric Capital Corporation, a GECDF affiliate, and the partnership agreement was amended to provide that Polaris Acceptance would continue to sell portions of its receivable portfolio to the Securitization Facility from time to time on an ongoing basis. The sale of receivables from Polaris Acceptance to the Securitization Facility is accounted for in Polaris Acceptance’s financial statements as a “true-sale” under ASC Topic 860. Polaris Acceptance is not responsible for any continuing servicing costs or obligations with respect to the Securitized Receivables. The remaining portion of the receivable portfolio is recorded on Polaris Acceptance’s books, and is funded to the extent of 85 percent through a loan from an affiliate of GECDF.

We have not guaranteed the outstanding indebtedness of Polaris Acceptance or the Securitized Receivables. In addition, the two partners of Polaris Acceptance share equally an equity cash investment equal to 15 percent of the sum of the portfolio balance in Polaris Acceptance plus the Securitized Receivables. Our total investment in Polaris Acceptance at June 30, 2011 was $35.6 million. Substantially all of our U.S. sales are financed through Polaris Acceptance and the Securitization Facility whereby Polaris receives payment within a few days of shipment of the product. The partnership agreement provides that all income and losses of the Polaris Acceptance portfolio and income and losses realized by GECDF’s affiliates with respect to the Securitized Receivables are shared 50 percent by our wholly-owned subsidiary and 50 percent by GECDF’s subsidiary. Polaris’ exposure to losses associated with respect to the Polaris Acceptance Portfolio and the Securitized Receivables is limited to its equity in its wholly-owned subsidiary that is a partner in Polaris Acceptance. We have agreed to repurchase products repossessed by Polaris Acceptance or the Securitization Facility up to an annual maximum of 15 percent of the aggregate average month-end balances outstanding during the prior calendar year with respect to receivables retained by Polaris Acceptance and Securitized Receivables. For calendar year 2011, the potential 15 percent aggregate repurchase obligation is approximately $74.1 million. Our financial exposure under this arrangement is limited to the difference between the amount paid to the finance company for repurchases and the amount received on the resale of the repossessed product. No material losses have been incurred under this agreement. During February 2011, Polaris and GECDF amended and restated its Polaris Acceptance partnership agreement through February 2017 with similar terms to the previous agreement.

Our investment in Polaris Acceptance is accounted for under the equity method, and is recorded as Investments in finance affiliate in the accompanying consolidated balance sheets. Our allocable share of the income of Polaris Acceptance and the Securitized Receivables has been included as a component of Income from financial services in the accompanying consolidated statements of income. At June 30, 2011, Polaris Acceptance’s wholesale portfolio receivables from dealers in the United States (including the Securitized Receivables) was $454.8 million, a seven percent increase from $425.4 million at June 30, 2010. Credit losses in the Polaris Acceptance portfolio have been modest, averaging less than one percent of the portfolio.

In April 2006, a wholly owned subsidiary of Polaris entered into a multi-year contract with GE Money Bank (“GE Bank”) under which GE Bank makes available closed-end installment consumer and commercial credit to customers of Polaris dealers for Polaris products. In November 2010, the Company extended its installment credit agreement to March 2016 under which GE Bank provides installment credit lending for motorcycles. Polaris’ income generated from the GE Bank agreement has been included as a component of Income from financial services in the accompanying consolidated statements of income.

In January 2009, a wholly owned subsidiary of Polaris entered into a multi-year contract with Sheffield Financial (“Sheffield”) pursuant to which Sheffield agreed to make available closed-end installment consumer and commercial credit to customers of Polaris dealers for Polaris products in the United States. In October 2010, the Company extended its installment credit agreement with Sheffield to February 2016 under which Sheffield provides exclusive installment credit lending for ORV, Snowmobiles and certain other Polaris products. Polaris’ income generated from the Sheffield agreement has been included as a component of Income from financial services in the accompanying consolidated statements of income.

In August 2005, a wholly owned subsidiary of Polaris entered into a multi-year contract with HSBC under which HSBC manages the Polaris private label revolving credit card program under the StarCard label. During the 2010 second quarter, Polaris and HSBC extended the term of the agreement on similar terms to October 2013. Polaris’ income generated from the HSBC agreement has been included as a component of Income from financial services in the accompanying consolidated statements of income.

Inflation and Foreign Exchange Rates

Commodity inflation has had an impact on the results of Polaris’ recent operations. The changing relationships of the U.S. dollar to the Japanese yen, the Canadian dollar, the Euro and other foreign currencies have also had a material impact from time to time.

During calendar year 2010, purchases totaling approximately five percent of our cost of sales were from yen-denominated suppliers. Our cost of sales in the second quarter ended June 30, 2011 was negatively impacted by the Japanese yen-U.S. dollar exchange rate fluctuation when compared to the same period in 2010. At June 30, 2011, we had no Japanese yen foreign exchange hedging contracts in place. In view of current exchange rates, we anticipates that the Japanese yen-U.S. dollar exchange rate will have a negative impact on cost of sales for the remainder of 2011 when compared to the same periods in the prior year.

We operate in Canada through a wholly owned subsidiary. The weakening of the U.S. dollar in relation to the Canadian dollar has resulted in higher sales and gross margin levels in the second quarter and six months ended June 30, 2011 when compared to the same periods in 2010. At June 30, 2011, we had open Canadian dollar foreign exchange hedging contracts in place through December 2012. The notional amount for 2011 contracts total $148.3 million with an average exchange rate of approximately 0.98 U.S. dollar to Canadian dollar. The notional amount for 2012 contracts is $114.4 million at an average exchange rate of approximately 1.01 U.S. Dollar to Canadian dollar. In view of current exchange rates and the foreign exchange hedging contracts currently in place, we anticipates that the Canadian dollar-U.S. dollar exchange rate will have a positive impact on sales and net income for the remainder of 2011 when compared to the same periods in the prior year.

22

We operate in various countries, principally in Europe, through wholly owned subsidiaries and also sells to certain distributors in other countries and purchases components from certain suppliers directly for its U.S. operations in transactions denominated in Euros and other foreign currencies. The fluctuation of the U.S. dollar in relation to the Euro has resulted in an approximately neutral impact on gross margins for the second quarter and six month periods of 2011 when compared to the same period in 2010. We had open Swedish Krona and Australian Dollar foreign exchange hedging contracts in place through December 2011 and December 2012, respectively. The open Swedish Krona contracts through December 2011, had notional amounts totaling $6.0 million with an average exchange rate of approximately .15 U.S. dollar to the Swedish Krona. The open Australian Dollar contracts for 2011 had notional amounts totaling $6.0 million with an average exchange rate of approximately .96 U.S. dollar to the Australian Dollar. The open Australian Dollar contracts for 2012 had notional amounts totaling $3.6 million with an average exchange rate of approximately 1.02 U.S. dollar to Australian dollar. In view of the current exchange rates and the foreign exchange hedging contracts currently in place, we anticipate that the exchange rates for other foreign currencies will have a positive impact on sales and net income for the remainder of 2011 when compared to the same periods in the prior year.

The assets and liabilities in all Polaris foreign entities are translated at the foreign exchange rate in effect at the balance sheet date. Translation gains and losses are reflected as a component of Accumulated other comprehensive income, net in the Shareholders’ Equity section of the accompanying consolidated balance sheet. Revenues and expenses in all Polaris foreign entities are translated at the average foreign exchange rate in effect for each month of the quarter.

We are subject to market risk from fluctuating market prices of certain purchased commodities and raw materials including steel, aluminum, diesel fuel, natural gas, and petroleum-based resins. In addition, we are a purchaser of components and parts containing various commodities, including steel, aluminum, rubber and others, which are integrated into the Company’s end products. While such materials are typically available from numerous suppliers, commodity raw materials are subject to price fluctuations. We generally buys these commodities and components based upon market prices that are established with the vendor as part of the purchase process and from time to time will enter into derivative contracts to hedge a portion of the exposure to commodity risk. At June 30, 2011 there were derivative contracts in place to hedge a portion of our aluminum and diesel fuel exposures during 2011. Based on our current outlook for commodity prices, the total impact of commodities is expected to have a negative impact on our gross margins for the remainder of 2011 when compared to the same periods in the prior year.

Item 4

CONTROLS AND PROCEDURES

The Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and its Vice President — Finance and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15) as of the end of the period covered by this report. Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q the Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934 is (1) recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and (2) accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, in a manner that allows timely decisions regarding required disclosure. There have been no changes in the Company’s internal controls over financial reporting during the period covered by this quarterly report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting.

Item 4 — Submission of Matters to a Vote of Security Holders

The Company held its annual meeting of shareholders on April 28, 2011 at which time shareholders narrowly approved, on an advisory basis, to have future votes held on the Company’s executive compensation program annually until determined otherwise by the Company’s Board of Directors. On July 20, 2011, the Board of Directors adopted a resolution providing for an annual advisory vote on the Company’s executive compensation program. Additionally, as a result of the narrow margin of the voting results, the Board of Directors voted to submit the frequency vote to shareholders again at next year’s 2012 annual meeting of shareholders.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company utilizes the market approach to measure fair value for its non-qualified deferred compensation assets and the income approach for the interest rate swap agreements, foreign currency contracts and commodity contracts. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities and for the income approach the Company uses significant other observable inputs such as quotations from third parties, to value its derivative instruments used to hedge interest rate volatility and foreign currency and commodity transactions (see Note 10 for additional details). Assets and liabilities measured at fair value on a recurring basis are summarized below (in thousands):

	Fair Value Measurements as of June 30, 2011

Manufacturing Realignment

NOTE 12. Manufacturing Realignment

In May 2010, the Company announced that it was realigning its manufacturing operations. The realignment will consolidate operations into existing operations in Roseau, MN and Spirit Lake, IA as well as establish a new facility in Monterrey, Mexico. The realignment will lead to the sale or closure of a portion of the Osceola, WI manufacturing operations by 2012. Due to the increased demand for Polaris product, in April 2011, the Company reconsidered its decision regarding the Osceola operations and announced that it would maintain its snowmobile and motorcycle engine assembly in Osceola, WI. The Company expects to record transition charges, including both exit costs and startup costs, over the 2010 to 2012 periods. The exit costs pertaining to the manufacturing realignment are expected to total approximately $10,000,000 over that time period. The exit costs are classified within cost of sales in the consolidated statements of income. A summary of these exit costs follows (in thousands):

	Total Amount Expected to  be Incurred		Amount Incurred during the Three Months Ended June 30, 2011			Cumulative Amounts Incurred through June 30, 2011

Basis of Presentation

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial statements and, therefore, do not include all information and disclosures of results of operations, financial position and changes in cash flow in conformity with accounting principles generally accepted in the United States for complete financial statements. Accordingly, such statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 previously filed with the Securities and Exchange Commission. In the opinion of management, such statements reflect all adjustments (which include only normal recurring adjustments) necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. Due to the seasonality of the Snowmobiles; Off-Road Vehicles (“ORV”), which includes all-terrain vehicles (“ATV”) and side-by-side vehicles; On-Road Vehicles, which is comprised of motorcycles and electric vehicles; and Parts, Garments and Accessories (“PG&A”) businesses, and to certain changes in production and shipping cycles, results of such periods are not necessarily indicative of the results to be expected for the complete year.

Product Warranties

Product Warranties

Polaris provides a limited warranty for ORVs for a period of six months and for a period of one year for its snowmobiles and motorcycles. Polaris may provide longer warranties related to certain promotional programs, as well as longer warranties in certain geographical markets as determined by local regulations and market conditions. Polaris’ standard warranties require the Company or its dealers to repair or replace defective product during such warranty period at no cost to the consumer. The warranty reserve is established at the time of sale to the dealer or distributor based on management’s best estimate using historical rates and trends. Adjustments to the warranty reserve are made from time to time as actual claims become known in order to properly estimate the amounts necessary to settle future and existing claims on products sold as of the balance sheet date. Factors that could have an impact on the warranty accrual in any given period include the following: improved manufacturing quality, shifts in product mix, changes in warranty coverage periods, snowfall and its impact on snowmobile usage, product recalls and any significant changes in sales volume.

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities

NOTE 10. Derivative Instruments and Hedging Activities

The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by using derivative instruments are foreign currency risk, interest rate risk and commodity price fluctuations. Derivative contracts on various currencies are entered into in order to manage foreign currency exposures associated with certain product sourcing activities and intercompany sales. Interest rate swaps are entered into in order to manage interest rate risk associated with the Company’s variable-rate borrowings. Commodity hedging contracts are entered into in order to manage fluctuating market prices of certain purchased commodities and raw materials that are integrated into the Company’s end products.

The Company’s foreign currency management objective is to mitigate the potential impact of currency fluctuations on the value of its U.S. dollar cash flows and to reduce the variability of certain cash flows at the subsidiary level. The Company actively manages certain forecasted foreign currency exposures and uses a centralized currency management operation to take advantage of potential opportunities to naturally offset foreign currency exposures against each other. The decision of whether and when to execute derivative instruments, along with the duration of the instrument, can vary from period to period depending on market conditions, the relative costs of the instruments and capacity to hedge. The duration is linked to the timing of the underlying exposure, with the connection between the two being regularly monitored. Polaris does not use any financial contracts for trading purposes. At June 30, 2011, Polaris had the following open contracts (in thousands):

Foreign Currency	Notional Amounts (in US Dollars)		Unrealized Loss
Australian Dollar	$	9,599	$	(625	)
Canadian Dollar		262,653		(6,526	)
Swedish Krona		5,958		(233	)
Total	$	278,210	$	(7,384	)

These contracts, with maturities through December 2012, met the criteria for cash flow hedges and the unrealized gains or losses, after tax, are recorded as a component of Accumulated other comprehensive income in Shareholders’ Equity.

Polaris has entered into derivative contracts to hedge a portion of the exposure related to diesel fuel and aluminum for 2011. These diesel fuel and aluminum derivative contracts did not meet the criteria for hedge accounting.

For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of Accumulated other comprehensive income and reclassified into the income statement in the same period or periods during which the hedged transaction affects the income statement. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in the current income statement. The table below provides data about the amount of gains and losses, net of tax, related to derivative instruments designated as cash flow hedges included in Accumulated other comprehensive income for the three months ended June 30 (in thousands):

The ineffective portion of foreign currency contracts was not material for the three and six months ended June 30, 2011.

The Company recognized a loss of 2,000 and a gain of $661,000 in cost of sales on commodity contracts not designated as hedging instruments for the three and six month periods ended June 30, 2011, respectively, versus losses of $2,544,000 and $2,438,000 for the three and six month periods ended June 30, 2010.

Shareholders' Equity

NOTE 8. Shareholders’ Equity

During the first six months of 2011, Polaris paid $32,856,000 to repurchase and retire approximately 419,000 shares of its common stock related primarily to open market share repurchases. As of June 30, 2011, the Company has authorization from its Board of Directors to repurchase up to an additional 2,700,000 shares of Polaris stock. The repurchase of any or all such shares authorized for repurchase will be governed by applicable SEC rules and dependent on management’s assessment of market conditions. Polaris paid a regular cash dividend of $0.45 per share on May 16, 2011 to holders of record on May 2, 2011. On July 20, 2011, the Polaris Board of Directors declared a regular cash dividend of $0.45 per share payable on or about August 15, 2011 to holders of record of such shares at the close of business on August 1, 2011.

Net Income per Share

Basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during each period, including shares earned under the nonqualified deferred compensation plan (“Director Plan”), the ESOP and deferred stock units under the Omnibus Incentive Plan (“Omnibus Plan”). Diluted earnings per share is computed under the treasury stock method and is calculated to compute the dilutive effect of outstanding stock options issued under the 1995 Stock Option Plan and the 2003 Non-Employee Director Stock Option Plan (collectively, the “Option Plans”) and the Omnibus Plan and certain shares issued under the Restricted Stock Plan (“Restricted Plan”). A reconciliation of these amounts is as follows (in thousands):

	For the Three  Months Ended June 30,				For the Six Months Ended June 30,
	2011		2010		2011		2010
Weighted average number of common shares outstanding		34,174		32,956		34,101		32,851
Director plan and deferred stock units		170		161		167		168
ESOP		61		138		69		143
Common shares outstanding — basic		34,405		33,255		34,337		33,162
Dilutive effect of Restricted Plan and Omnibus Plan		94		66		86		62
Dilutive effect of Option Plans and Omnibus Plan		1,108		927		1,046		775
Common and potential common shares outstanding — diluted		35,607		34,248		35,469		33,999

During the second quarter and year-to-date periods ending June 30, 2011, the number of options that could potentially dilute earnings per share on a fully diluted basis that were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive were approximately 30,000 and 250,000, respectively, compared to 291,000 and 2,701,000, respectively, for the same periods in 2010.

Comprehensive Income

Comprehensive income represents net income adjusted for foreign currency translation adjustments, realized and unrealized gains or losses on available for sale securities and deferred gains or losses on derivative instruments utilized to hedge Polaris’ interest and foreign exchange exposures.

Significant Accounting Policies

NOTE 1. Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial statements and, therefore, do not include all information and disclosures of results of operations, financial position and changes in cash flow in conformity with accounting principles generally accepted in the United States for complete financial statements. Accordingly, such statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2010 previously filed with the Securities and Exchange Commission. In the opinion of management, such statements reflect all adjustments (which include only normal recurring adjustments) necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. Due to the seasonality of the Snowmobiles; Off-Road Vehicles (“ORV”), which includes all-terrain vehicles (“ATV”) and side-by-side vehicles; On-Road Vehicles, which is comprised of motorcycles and electric vehicles; and Parts, Garments and Accessories (“PG&A”) businesses, and to certain changes in production and shipping cycles, results of such periods are not necessarily indicative of the results to be expected for the complete year.

Product Warranties

Polaris provides a limited warranty for ORVs for a period of six months and for a period of one year for its snowmobiles and motorcycles. Polaris may provide longer warranties related to certain promotional programs, as well as longer warranties in certain geographical markets as determined by local regulations and market conditions. Polaris’ standard warranties require the Company or its dealers to repair or replace defective product during such warranty period at no cost to the consumer. The warranty reserve is established at the time of sale to the dealer or distributor based on management’s best estimate using historical rates and trends. Adjustments to the warranty reserve are made from time to time as actual claims become known in order to properly estimate the amounts necessary to settle future and existing claims on products sold as of the balance sheet date. Factors that could have an impact on the warranty accrual in any given period include the following: improved manufacturing quality, shifts in product mix, changes in warranty coverage periods, snowfall and its impact on snowmobile usage, product recalls and any significant changes in sales volume. The activity in Polaris’ accrued warranty reserve for the periods presented is as follows (in thousands):

Financing Agreement

NOTE 4. Financing Agreement

Polaris is a party to an unsecured bank agreement comprised of a $250,000,000 revolving loan facility for working capital needs. As part of the bank agreement, the Company had a $200,000,000 term loan outstanding at December 31, 2010 and March 31, 2011, which was paid off in its entirety in May 2011 with the issuance of the Senior Notes described below and $100,000,000 of cash on hand. In anticipation of the Senior Notes being issued in May 2011, the Company classified $100,000,000 of the $200,000,000 term loan outstanding as of December 31, 2010 and March 31, 2011 as a long-term liability in each of the respective consolidated balance sheets. The bank agreement expires on December 2, 2011. There were no borrowings under the revolving loan facility at June 30, 2011.

In December 2010 the Company entered into a Master Note Purchase Agreement to issue $25,000,000 of 3.81 percent unsecured Senior Notes due May 2018 and $75,000,000 of 4.60 percent unsecured Senior Notes due May 2021 (collectively, “The Senior Notes”). The Senior Notes were issued in May 2011.

Polaris previously entered into various interest rate swap agreements to manage exposures to fluctuations in interest rates under the term loan by fixing the LIBOR interest rate. Each of these interest rate swaps were designated as and met the criteria of cash flow hedges. The swap agreements expired in April 2011.

The Company entered into and settled an interest rate lock contract in November 2010 in connection with the Master Note Purchase Agreement. The interest rate lock settlement resulted in a $251,000 gain, net of deferred taxes of $149,000, which is being amortized into income over the life of the related debt.

Financial Services Arrangements

NOTE 5. Financial Services Arrangements

In 1996, a wholly-owned subsidiary of Polaris entered into a partnership agreement with an entity that is now a subsidiary of GE Commercial Distribution Finance Corporation (“GECDF”) to form Polaris Acceptance. Polaris’ subsidiary has a 50 percent equity interest in Polaris Acceptance. In November 2006, Polaris Acceptance sold a majority of its receivable portfolio (the “Securitized Receivables”) to a securitization facility (“Securitization Facility”) arranged by General Electric Capital Corporation, a GECDF affiliate, and the partnership agreement was amended to provide that Polaris Acceptance would continue to sell portions of its receivable portfolio to the Securitization Facility from time to time on an ongoing basis. The sale of receivables from Polaris Acceptance to the Securitization Facility is accounted for in Polaris Acceptance’s financial statements as a “true-sale” under ASC Topic 860. Substantially all of Polaris’ U.S. sales are financed through Polaris Acceptance and the Securitization Facility whereby Polaris receives payment within a few days of shipment of the product. The net amount financed for dealers under this arrangement at June 30, 2011, including both the portfolio balance in Polaris Acceptance and the Securitized Receivables, was $454,782,000 which includes $171,213,000 in the Polaris Acceptance portfolio and $283,569,000 of Securitized Receivables. Polaris has agreed to repurchase products repossessed by Polaris Acceptance or the Securitization Facility up to an annual maximum of 15 percent of the aggregate average month-end balances outstanding during the prior calendar year with respect to receivables retained by Polaris Acceptance and Securitized Receivables. For calendar year 2011, the potential 15 percent aggregate repurchase obligation is approximately $74,073,000. Polaris’ financial exposure under this arrangement is limited to the difference between the amount paid to the finance company for repurchases and the amount received on the resale of the repossessed product. No material losses have been incurred under this agreement. Polaris’ total investment in Polaris Acceptance at June 30, 2011 of $35,567,000 is accounted for under the equity method, and is recorded as Investments in finance affiliate in the accompanying consolidated balance sheets. Polaris’ allocable share of the income of Polaris Acceptance and the Securitization Facility has been included as a component of Income from financial services in the accompanying consolidated statements of income. During February 2011, Polaris and GECDF amended and restated its Polaris Acceptance partnership agreement through February 2017 with similar terms to the previous agreement.

In August 2005, a wholly-owned subsidiary of Polaris entered into a multi-year contract with HSBC Bank Nevada, National Association (“HSBC”), formerly known as Household Bank (SB), N.A., under which HSBC manages the Polaris private label credit card program under the StarCard label, currently providing revolving retail credit for Polaris products. During the 2010 second quarter, Polaris and HSBC extended the agreement to October 2013. Polaris’ income generated from the HSBC agreement has been included as a component of Income from financial services in the accompanying consolidated statements of income.

In April 2006, a wholly-owned subsidiary of Polaris entered into a multi-year contract with GE Money Bank (“GE Bank”) under which GE Bank makes available closed-end installment consumer and commercial credit to customers of Polaris dealers for both Polaris and non-Polaris products. In November 2010, the Company extended its installment credit agreement to March 2016 under which GE Bank provides installment credit lending for motorcycles. Polaris’ income generated from the GE Bank agreement has been included as a component of Income from financial services in the accompanying consolidated statements of income. In January 2009, a wholly-owned subsidiary of Polaris entered into a multi-year contract with Sheffield Financial (“Sheffield”) pursuant to which Sheffield agreed to make available closed-end installment consumer and commercial credit to customers of Polaris dealers for Polaris products. In October 2010, Polaris extended its installment credit agreement to February 2016 under which Sheffield provides installment credit lending for ORVs, Snowmobiles and certain other Polaris products. Polaris’ income generated from the Sheffield agreement has been included as a component of Income from financial services in the accompanying consolidated statements of income.

Polaris also provides extended service contracts to consumers and certain insurance contracts to dealers and consumers through various third-party suppliers. Polaris does not retain any warranty, insurance or financial risk in any of these arrangements. Polaris’ service fee income generated from these arrangements has been included as a component of Income from financial services in the accompanying consolidated statements of income.

Share-Based Employee Compensation

Share-Based Employee Compensation

NOTE 2. Share-Based Employee Compensation

The amount of compensation cost for share-based awards to be recognized during a period is based on the portion of the awards that are ultimately expected to vest. The Company estimates option forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company analyzes historical data to estimate pre-vesting forfeitures and records share compensation expense for those awards expected to vest.

Total share-based compensation expenses are as follows (in thousands):

	For the Three Months Ended June 30,				For the Six Months  Ended June 30,
	2011		2010		2011		2010
Option plan	$	2,448	$	1,285	$	4,721	$	2,569
Other share-based awards		27,232		10,859		40,327		17,450
Total share-based compensation before tax		29,680		12,144		45,048		20,019
Tax benefit		11,229		4,823		17,095		7,859
Total share-based compensation expense included in net income	$	18,451	$	7,321	$	27,953	$	12,160

In addition to the above share-based compensation expense, Polaris sponsors a qualified non-leveraged employee stock ownership plan (“ESOP”). Shares allocated to eligible participants’ accounts vest at various percentage rates based on years of service and require no cash payments from the recipient.

At June 30, 2011 there was $25,159,000 of total unrecognized share-based compensation expense related to unvested share-based awards. Unrecognized share-based compensation expense is expected to be recognized over a weighted-average period of 1.8 years. Included in unrecognized share-based compensation is $19,009,000 related to stock options and $6,150,000 related to restricted stock.

Fair Value Measurements

NOTE 11. Fair Value Measurements

ASC Topic 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This topic also establishes a fair value hierarchy which requires classification based on observable and unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company utilizes the market approach to measure fair value for its non-qualified deferred compensation assets and the income approach for the interest rate swap agreements, foreign currency contracts and commodity contracts. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities and for the income approach the Company uses significant other observable inputs such as quotations from third parties, to value its derivative instruments used to hedge interest rate volatility and foreign currency and commodity transactions (see Note 10 for additional details). Assets and liabilities measured at fair value on a recurring basis are summarized below (in thousands):

	Fair Value Measurements as of June 30, 2011
