SUMMARY_OF_SIGNIFICANT_ACCOUNT

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Arctic Cat Inc. (the “Company”) designs, engineers, manufactures and markets snowmobiles and all-terrain vehicles (ATVs) and recreational off-highway vehicles (“side-by-sides” or “ROVs”) under the Arctic Cat® and MotorFist® brand names, and related parts, garments and accessories principally through its facilities in Thief River Falls, Minnesota. The Company’s products are sold through a network of independent dealers located throughout the United States, Canada, and Europe and through distributors in Europe, Russia, South America, the Middle East, Asia and other international markets.
	Use of Estimates
	Preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, related revenues and expenses and disclosure about contingent assets and liabilities at the date of the financial statements. Actual results could differ from the estimates used by management.
	Principles of Consolidation
	The consolidated financial statements include the accounts of Arctic Cat Inc. and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	Cash and Cash Equivalents
	The Company considers highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. At times, certain bank deposits may be in excess of federally insured limits. As of March 31, 2015 and 2014, the Company had approximately $19,212,000 and $14,948,000, respectively, of cash located in foreign banks primarily in Europe and Canada.
	Fair Values of Financial Instruments
	Except where noted, the carrying value of current financial assets and liabilities approximates their fair value, due to their short-term nature.
	Short-Term Investments
	Short-term investments are reported at fair value. The Company utilizes the specific identification method in accounting for its short-term investments.
	Accounts Receivable
	The Company’s accounts receivable balance consists of amounts due from its dealers and finance companies. The Company extends credit to its dealers based on an evaluation of the dealers’ financial condition. The Company’s collection exposure relating to accounts receivable amounts due from dealer floorplan finance companies is limited due to the financial strength of the finance companies and provisions of its existing agreements. Accounts receivable is presented net of an allowance for estimated uncollectible amounts due from its dealers. The Company estimates the uncollectible amounts considering numerous factors, mainly historical trends as well as current available information. The Company’s allowance for uncollectible accounts was $1,897,000 and $1,988,000 at March 31, 2015 and 2014, respectively. The activity within the allowance for uncollectible accounts for the three years ended March 31, 2015 was not significant. Accounts receivable amounts written off have been within management’s expectations.
	The activity in the allowance for uncollectible accounts for accounts receivable is as follows:
		2015			2014
	Balance at beginning of period	$	1,988,000		$	2,759,000
	Provisions charged to expense		287,000			(872,000	)
	Deductions for amounts written-off		(378,000	)		101,000
	Balance at end of period	$	1,897,000		$	1,988,000
	Inventories
	Inventories are stated at the lower of cost or market, with cost determined using the first-in, first-out method.
	Derivative Instruments and Hedging Activities
	The Company enters into forward exchange contracts to protect against exposure to currency fluctuations on transactions denominated in foreign currencies, namely Canadian dollar and Japanese yen. The contracts are designated as, and meet the criteria for, cash flow hedges. The Company does not enter into forward contracts for the purpose of trading. Gains and losses on forward contracts are recorded in accumulated other comprehensive income (loss), net of tax, and subsequently reclassified into operating expense upon completing transfers of Canadian dollar or Japanese yen funds.
	As of March 31, 2015, the Company had open Canadian dollar forward exchange contracts, maturing through March 2016, with notional amounts totaling $76,328,000 and the total net fair value of $3, 628,000 is included in accounts receivable. As of March 31, 2015, the Company had open Japanese yen forward exchange contracts, maturing through August 2015, with notional amounts totaling $19,046,000 and the total net fair value of $434,000 is included in accounts payable. As of March 31, 2014, the Company had open Canadian dollar forward exchange contracts, maturing through March 2014, with notional amounts totaling $89,649,000 and the total net fair value of $424,000 is included in accounts payable. The Company did not enter into any forward contracts in currencies other than the Canadian dollar in the year ended March 31, 2014 and the Canadian dollar and Japanese yen in the year ended March 31, 2015.
	Fair Value Measurements
	Fair value is defined 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. A fair value hierarchy has been established 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; and 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. As of March 31, 2015, the Company’s Canadian dollar foreign currency contracts fair value was an asset totaling $3,628,000 and considered a Level 2 measurement. As of March 31, 2015, the Company’s Japanese yen foreign currency contracts fair value was a liability totaling $434,000 and considered a Level 2 measurement. As of March 31, 2014, Company’s Canadian dollar foreign currency contract fair value was a liability totaling $424,000 and considered a Level 2 measurement. There were no open Japanese yen foreign currency contracts at March 31, 2014. The Company utilizes the income approach to measure fair value of foreign currency contracts which is based on significant other observable inputs. The asset or liability is measured at fair value on a recurring basis each reporting period end.
	Property and Equipment
	Depreciation is provided in amounts sufficient to relate the cost of depreciable assets to operations over their estimated service lives, using the straight-line method for all property, equipment and tooling. Repairs and maintenance cost that are considered not to extend the useful life of the property and equipment are expensed as incurred. Tooling is amortized over the life of the product, generally 3-5 years. Estimated service lives range from 15 - 39 years for buildings and improvements and 5 - 7 years for machinery and equipment. Accelerated and straight-line methods are used for income tax reporting.
	Impairment of Long-Lived Assets
	The Company evaluates the carrying value of long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the assets, the carrying value is reduced to the estimated fair value as measured by the associated discounted cash flows. Based on impairment indicators not being present, the Company determined the carrying value of long-lived assets was not impaired.
	Goodwill and Other Intangible Assets
	ASC Topic 350 prohibits the amortization of goodwill and intangible assets with indefinite useful lives. An impairment charge for goodwill is recognized only when the estimated fair value of a reporting unit, including goodwill, is less than its carrying amount. The Company has not performed the annual impairment test, since the acquisition of MotorFist occurred on February 25, 2015. In accordance with Topic 350, the Company will continue to complete an impairment analysis on an annual basis or more frequently if an event or circumstance that would more likely than not reduce the fair value of a reporting unit below its carrying amount occurs. Identified intangible assets are acquired customer relationships, homologation licenses, and a non-compete agreement. Goodwill, intangibles and other assets, consist of $6,579,000 net of accumulated amortization, for the period ended March 31, 2015. Goodwill, intangibles and other assets, consist $1,067,000 net of accumulated amortization, for the period ended March 31, 2014. Other assets consist of $436,000, net of accumulated amortization for period ended March 31, 2015 and 2014.
	Additions to goodwill and other intangible assets in fiscal year 2015 relate primarily to the acquisition of MotorFist, LLC, (“MotorFist”), in February 2015. MotorFist is an innovative growing company in the power sports apparel market with a strong reputation as a provider of technical snowmobile riding gear.
	For the acquisition, the aggregate purchase price was allocated to the assets acquired and liabilities assumed based on their fair values at the date of acquisition. MotorFist’s financial results are included in the Company’s consolidated results from the date of acquisition.
	The changes in the carrying amount of goodwill and other identified intangible assets for the fiscal years ended March 31, 2015 and 2014 are as follows:
		2015			2014
	Balance at beginning of period	$	631,000		$	659,000
	Goodwill acquired during the period		3,342,000			—
	Intangible assets acquired during the period		2,255,000			56,000

	Product Warranties
	The Company generally provides a limited warranty to the owner of snowmobiles for twelve months from the date of consumer registration and for six months from the date of consumer registration on ATVs and ROVs. The Company provides for estimated warranty costs at the time of sale based on historical rates and trends and makes subsequent adjustments to its estimate as actual claims become known or the amounts are determinable, including costs associated with safety recalls, which may occur after the standard warranty period. The following represents changes in the Company’s accrued warranty liability for the fiscal years ended March 31,
		2015			2014			2013

	Balance at end of period	$	23,062,000		$	19,357,000		$	18,709,000
	Insurance
	The Company is self-insured for employee medical, workers’ compensation, and product liability claims. Specific stop loss coverages are provided for catastrophic claims. Losses and claims are charged to operations when it is probable a loss has been incurred and the amount can be reasonably estimated.
	Revenue Recognition
	The Company recognizes revenue and provides for estimated marketing and sales incentive costs when products are shipped to dealers and distributors pursuant to their order, the price is fixed and collection is reasonably assured. Shipping and handling costs are recorded as a component of costs of goods sold and shipping charges to the dealers are recorded as revenue at the time products are shipped.
	Return allowances for parts and accessories are recorded as a reduction of revenue when the products are sold based on the company’s return allowance program and historical experience.
	Sales tax collected from customers is remitted to the appropriate taxing jurisdictions and is excluded from sales revenue as the Company considers itself a pass-through conduit for collecting and remitting sales taxes.
	Marketing and Sales Incentive Costs
	At the time product revenue is recognized the Company provides for various marketing and sales incentive costs that are offered to its dealers and consumers. Examples of these costs, which are recognized as a reduction of revenue when the products are sold, include dealer and consumer rebates, dealer floor plan financing assistance and other incentive and promotion programs. Generally, the Company records provisions for these marketing programs at the later of when the revenue is recognized or when the sales incentive or marketing program is approved and communicated for products previously shipped. Sales incentives that involve a free product or service delivered to the consumer are recorded as a component of cost of goods sold. The Company estimates the costs of these various incentive and marketing programs at the time of sale or subsequently when programs are approved and communicated based on historical experience. To the extent current experience differs with previous estimates the accrued liability for marketing and sales incentives is adjusted accordingly.
	Dealer Holdback
	The Company records a dealer holdback program liability at the time certain products are shipped to its dealers. If the products subject to the holdback program are sold within the program time period, the Company refunds a portion of the original sale price, referred to as dealer holdback, to the dealer within the program time period and refunds any remaining balances to its dealers when the program time periods end. The Company’s dealer holdback program liability, included within accounts payable, was $19,751,000 and $19,448,000 as of March 31, 2015 and 2014, respectively.
	Research and Development
	Research and development costs are expensed as incurred. Research and development expense was $24,341,000, $23,998,000 and $20,693,000 during fiscal 2015, 2014 and 2013, respectively.
Advertising
The Company expenses advertising costs as incurred, except for cooperative advertising obligations arising related to the sale of the Company’s products to its dealers. The estimated cost of cooperative advertising, which the dealer is required to support, is recorded as marketing expense at the time the product is sold. Cooperative advertising was $3,566,000, $3,440,000 and $3,556,000 in fiscal 2015, 2014 and 2013, respectively. Total advertising expense, including cooperative advertising, was $18,588,000, $17,562,000 and $17,232,000 in fiscal 2015, 2014 and 2013, respectively.
Net Earnings Per Share
The Company’s diluted weighted average shares outstanding include common shares and common share equivalents relating to stock options, when dilutive. Options to purchase 156,432 shares of common stock with weighted average exercise prices of $44.14 were outstanding during fiscal 2015 but were excluded from the computation of common share equivalents because they were anti-dilutive. No options outstanding were excluded from the computation of common share equivalents during fiscal 2014. Options to purchase 70,470 shares of common stock with weighted average exercise prices of $43.79 were outstanding during fiscal 2013 but were excluded from the computation of common share equivalents because they were anti-dilutive.

	The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company recognizes potential interest and penalties related to income tax positions as a component of the provision for income taxes on the consolidated statements of operations. The Company had liabilities recorded related to unrecognized tax benefits totaling $2,215,000 and $2,025,000 at March 31, 2015 and 2014, including reserves related to potential interest and penalties of $387,000 and $318,000, respectively. The amount of the liability, net of federal benefits for uncertain state tax positions, at March 31, 2015, if recognized, would affect the Company’s effective tax rate. The Company currently anticipates approximately $236,000 of unrecognized tax benefits will be recognized during the next twelve months. The Company has state research and development credit carryforwards of $1,043,000 and $703,000 offset by valuation allowances as of March 31, 2015 and 2014, respectively, with expiration dates to March 2030. With few exceptions, the Company is no longer subject to federal, state, or foreign income tax examinations for years prior to March 31, 2011. A reconciliation of the amount of unrecognized tax benefits excluding interest and penalties is as follows:
		2015			2014

	Dealer Financing
	Finance companies provide the Company’s North American dealers with floorplan financing. The Company has agreements with these finance companies to repurchase certain repossessed products sold to its dealers. At March 31, 2015, the Company was contingently liable under these agreements for a maximum repurchase amount of approximately $69,324,000. The Company’s financial exposure under these agreements is limited to the difference between the amount paid to the finance companies for repurchases and the amount received upon the resale of the repossessed product. Losses incurred under these agreements during the periods presented have not been material. The financing agreements also have loss sharing provisions should any dealer default, whereby the Company shares certain losses with the finance companies. The maximum liability to the Company under these provisions is approximately $2,388,000 at March 31, 2015.
	Litigation
	The Company is subject to legal proceedings and claims which arise in the ordinary course of business. Accidents involving personal injury and property damage may occur in the use of snowmobiles, ATVs and ROVs. Claims have been made against the Company from time to time relating to these accidents, and from time to time, parties assert claims relating to their intellectual property. It is the Company’s policy to vigorously defend against these actions. The Company is not involved in any legal proceedings which it believes will have the potential for a materially adverse impact on the Company’s business or financial condition, results of operations or cash flows. The Company has recorded a reserve based on its estimated range of potential exposures based on the legal proceedings and claims that it is aware of. Should any settlement occur that exceeds the Company’s estimate or a new claim arise, the Company may need to adjust its overall reserve and, depending on the amount, such adjustment could be material.
	Leases
	The Company leases buildings and equipment under non-cancelable operating leases. Total rent expense under all lease agreements was $1,942,000, $1,413,000 and $1,111,000 for fiscal 2015, 2014 and 2013, respectively. Future minimum lease payments, exclusive of other costs required under non-cancelable operating leases at March 31, 2015 are approximately $239,000 in fiscal years 2016 through 2018 and $92,000 in fiscal years 2019 and 2020.

	Stock Option Plans
	The Company has outstanding equity awards under a 2013 Omnibus Stock and Incentive Plan (the “2013 Plan”) and a 2007 Omnibus Stock and Incentive Plan (the “2007 Plan,” and along with the 2013 Plan, the “Plans”), previously approved by the Company’s shareholders. The Plans provide for incentive and non-qualified stock options, restricted stock and restricted stock unit awards and other incentive awards to be granted to directors, officers, other key employees and consultants. The stock options granted generally have a five to ten year life, vest over a period of one to three years, and have an exercise price equal to the fair market value of the stock on the date of grant. The stock options are generally subject to accelerated vesting if there is a change in control, as defined in the plans. The restricted stock awards generally vest over a period of two to three years and do not require cash payments from restricted stock award recipients. At March 31, 2015, the Company had 808,807 shares of common stock available for grant under the plans.
	For the fiscal years ended March 31, 2015, 2014 and 2013, the Company recorded stock-based compensation expense for stock options and restricted stock awards of $4,087,000, $2,584,000 and $2,337,000, respectively, which have been included in general and administrative expenses. The Company’s total stock-based compensation expense reduced both basic and diluted earnings per share by $0.24, $0.12 and $0.11 for the fiscal years ended March 31, 2015, 2014 and 2013, respectively. At March 31, 2015, the Company had $8,045,000 of unrecognized compensation costs related to non-vested stock options and restricted stock awards that are expected to be recognized over a weighted average period of approximately two years.
	The fair value of each stock option award was estimated on the date of grant using the Black-Scholes options pricing model. The following assumptions were used to estimate the fair value of options:
		2015			2014		2013
	Assumptions:

	Stock options outstanding had an aggregate intrinsic value of $5,332,000 at March 31, 2015 and a weighted-average contractual life of 8.03 years. Exercisable stock options had an aggregate intrinsic value of $4,587,000 at March 31, 2015 and a weighted-average contractual life of 6.38 years. The aggregate intrinsic value is based on the difference between the exercise price and the Company’s March 31, 2015 common share market value for in-the-money options.
	The following tables summarize information concerning currently outstanding and exercisable stock options at March 31, 2015:

	The expected term of options granted is the safe harbor period. The volatility is based on historic volatilities from the traded shares of the Company over the past six years. The risk-free interest rate for periods matching the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected dividend is based on the historic dividend of the Company. The Company has analyzed the forfeitures of stock and option grants and has used a ten percent forfeiture rate in the expense calculation.
	Restricted Stock
	The 2013 Plan provides for grants of restricted common stock and restricted stock units to executives and key employees of the Company. The restricted common stock and restricted stock units are valued based on the Company’s market value of common stock on the date of grant and the amount of any award is expensed over the requisite service period which approximates two to three years. If grantees are retirement eligible and awards would either fully vest upon retirement or continue to vest after retirement, the full amount of the related expense is recognized upon grant. At March 31, 2015, the Company had no shares of restricted common stock issued and outstanding and 11,895 unvested restricted stock units outstanding under the 2007 Plan and 22,500 shares of restricted common stock issued and outstanding and 43,810 unvested restricted stock units outstanding under the 2013 Plan and 60,734 unvested restricted stock units outstanding under a Board of Directors authorized executive inducement grant. The shares of restricted common stock awarded have voting rights and participate equally in all dividends and other distributions duly declared by the Company’s Board of Directors.
	Restricted stock and restricted stock unit award activity under the Plans for the fiscal years ended March 31, 2015 and 2014 is summarized as follows:

Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	K. RECENT ACCOUNTING PRONOUNCEMENTS
	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, which provides guidance for revenue recognition that supersedes existing revenue recognition guidance (but does not apply to nor supersede accounting guidance for lease contracts). The ASU’s core principle is that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The ASU is effective for reporting periods beginning after December 15, 2017, and should be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the ASU recognized at the date of initial application. The Company is currently in the process of evaluating the impact of the adoption of this ASU on the Company’s consolidated results.

SUMMARY_OF_SIGNIFICANT_ACCOUNT1

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates
	Preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, related revenues and expenses and disclosure about contingent assets and liabilities at the date of the financial statements. Actual results could differ from the estimates used by management.
Principles of Consolidation	Principles of Consolidation
	The consolidated financial statements include the accounts of Arctic Cat Inc. and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Cash and Cash Equivalents	Cash and Cash Equivalents
	The Company considers highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. At times, certain bank deposits may be in excess of federally insured limits. As of March 31, 2015 and 2014, the Company had approximately $19,212,000 and $14,948,000, respectively, of cash located in foreign banks primarily in Europe and Canada.
Fair Values of Financial Instruments	Fair Values of Financial Instruments
	Except where noted, the carrying value of current financial assets and liabilities approximates their fair value, due to their short-term nature.
Short-Term Investments	Short-Term Investments
	Short-term investments are reported at fair value. The Company utilizes the specific identification method in accounting for its short-term investments.
Accounts Receivable	Accounts Receivable
	The Company’s accounts receivable balance consists of amounts due from its dealers and finance companies. The Company extends credit to its dealers based on an evaluation of the dealers’ financial condition. The Company’s collection exposure relating to accounts receivable amounts due from dealer floorplan finance companies is limited due to the financial strength of the finance companies and provisions of its existing agreements. Accounts receivable is presented net of an allowance for estimated uncollectible amounts due from its dealers. The Company estimates the uncollectible amounts considering numerous factors, mainly historical trends as well as current available information. The Company’s allowance for uncollectible accounts was $1,897,000 and $1,988,000 at March 31, 2015 and 2014, respectively. The activity within the allowance for uncollectible accounts for the three years ended March 31, 2015 was not significant. Accounts receivable amounts written off have been within management’s expectations.
	The activity in the allowance for uncollectible accounts for accounts receivable is as follows:
		2015			2014
	Balance at beginning of period	$	1,988,000		$	2,759,000
	Provisions charged to expense		287,000			(872,000	)
	Deductions for amounts written-off		(378,000	)		101,000
	Balance at end of period	$	1,897,000		$	1,988,000
Inventories	Inventories
	Inventories are stated at the lower of cost or market, with cost determined using the first-in, first-out method.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities
	The Company enters into forward exchange contracts to protect against exposure to currency fluctuations on transactions denominated in foreign currencies, namely Canadian dollar and Japanese yen. The contracts are designated as, and meet the criteria for, cash flow hedges. The Company does not enter into forward contracts for the purpose of trading. Gains and losses on forward contracts are recorded in accumulated other comprehensive income (loss), net of tax, and subsequently reclassified into operating expense upon completing transfers of Canadian dollar or Japanese yen funds.
	As of March 31, 2015, the Company had open Canadian dollar forward exchange contracts, maturing through March 2016, with notional amounts totaling $76,328,000 and the total net fair value of $3, 628,000 is included in accounts receivable. As of March 31, 2015, the Company had open Japanese yen forward exchange contracts, maturing through August 2015, with notional amounts totaling $19,046,000 and the total net fair value of $434,000 is included in accounts payable. As of March 31, 2014, the Company had open Canadian dollar forward exchange contracts, maturing through March 2014, with notional amounts totaling $89,649,000 and the total net fair value of $424,000 is included in accounts payable. The Company did not enter into any forward contracts in currencies other than the Canadian dollar in the year ended March 31, 2014 and the Canadian dollar and Japanese yen in the year ended March 31, 2015.
Fair Value Measurements	Fair Value Measurements
	Fair value is defined 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. A fair value hierarchy has been established 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; and 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. As of March 31, 2015, the Company’s Canadian dollar foreign currency contracts fair value was an asset totaling $3,628,000 and considered a Level 2 measurement. As of March 31, 2015, the Company’s Japanese yen foreign currency contracts fair value was a liability totaling $434,000 and considered a Level 2 measurement. As of March 31, 2014, Company’s Canadian dollar foreign currency contract fair value was a liability totaling $424,000 and considered a Level 2 measurement. There were no open Japanese yen foreign currency contracts at March 31, 2014. The Company utilizes the income approach to measure fair value of foreign currency contracts which is based on significant other observable inputs. The asset or liability is measured at fair value on a recurring basis each reporting period end.
Property and Equipment	Property and Equipment
	Depreciation is provided in amounts sufficient to relate the cost of depreciable assets to operations over their estimated service lives, using the straight-line method for all property, equipment and tooling. Repairs and maintenance cost that are considered not to extend the useful life of the property and equipment are expensed as incurred. Tooling is amortized over the life of the product, generally 3-5 years. Estimated service lives range from 15 - 39 years for buildings and improvements and 5 - 7 years for machinery and equipment. Accelerated and straight-line methods are used for income tax reporting.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets
	The Company evaluates the carrying value of long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the assets, the carrying value is reduced to the estimated fair value as measured by the associated discounted cash flows. Based on impairment indicators not being present, the Company determined the carrying value of long-lived assets was not impaired.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets
	ASC Topic 350 prohibits the amortization of goodwill and intangible assets with indefinite useful lives. An impairment charge for goodwill is recognized only when the estimated fair value of a reporting unit, including goodwill, is less than its carrying amount. The Company has not performed the annual impairment test, since the acquisition of MotorFist occurred on February 25, 2015. In accordance with Topic 350, the Company will continue to complete an impairment analysis on an annual basis or more frequently if an event or circumstance that would more likely than not reduce the fair value of a reporting unit below its carrying amount occurs. Identified intangible assets are acquired customer relationships, homologation licenses, and a non-compete agreement. Goodwill, intangibles and other assets, consist of $6,579,000 net of accumulated amortization, for the period ended March 31, 2015. Goodwill, intangibles and other assets, consist $1,067,000 net of accumulated amortization, for the period ended March 31, 2014. Other assets consist of $436,000, net of accumulated amortization for period ended March 31, 2015 and 2014.
	Additions to goodwill and other intangible assets in fiscal year 2015 relate primarily to the acquisition of MotorFist, LLC, (“MotorFist”), in February 2015. MotorFist is an innovative growing company in the power sports apparel market with a strong reputation as a provider of technical snowmobile riding gear.
	For the acquisition, the aggregate purchase price was allocated to the assets acquired and liabilities assumed based on their fair values at the date of acquisition. MotorFist’s financial results are included in the Company’s consolidated results from the date of acquisition.
	The changes in the carrying amount of goodwill and other identified intangible assets for the fiscal years ended March 31, 2015 and 2014 are as follows:
		2015			2014
	Balance at beginning of period	$	631,000		$	659,000
	Goodwill acquired during the period		3,342,000			—
	Intangible assets acquired during the period		2,255,000			56,000
	Currency translation effect on foreign balances		-2,000			-1,000
	Current year amortization		-83,000			(83,000	)
	Balance at end of period	$	6,143,000		$	631,000
	Identified intangible assets are acquired customer relationships, homologation licenses, non-compete agreements, trademarks/names, dealer network and in-process research and development. Intangible assets before accumulated amortization were $4,314,000 at March 31, 2015 and $2,060,000 at March 31, 2014. Accumulated amortization was $1,511,000 and $1,428,000 at March 31, 2015 and 2014, respectively. Amortization expense is expected to be approximately $383,000 in each of fiscal 2016, 2017, 2018, 2019 and 2020.
Product Warranties	Product Warranties
	The Company generally provides a limited warranty to the owner of snowmobiles for twelve months from the date of consumer registration and for six months from the date of consumer registration on ATVs and ROVs. The Company provides for estimated warranty costs at the time of sale based on historical rates and trends and makes subsequent adjustments to its estimate as actual claims become known or the amounts are determinable, including costs associated with safety recalls, which may occur after the standard warranty period. The following represents changes in the Company’s accrued warranty liability for the fiscal years ended March 31,
		2015			2014			2013
	Balance at beginning of period	$	19,357,000		$	18,709,000		$	18,521,000
	Warranty provision		21,499,000			16,770,000			19,449,000
	Warranty claim payments		(17,794,000	)		(16,122,000	)		(19,261,000	)
	Balance at end of period	$	23,062,000		$	19,357,000		$	18,709,000
Insurance	Insurance
	The Company is self-insured for employee medical, workers’ compensation, and product liability claims. Specific stop loss coverages are provided for catastrophic claims. Losses and claims are charged to operations when it is probable a loss has been incurred and the amount can be reasonably estimated.
Revenue Recognition	Revenue Recognition
	The Company recognizes revenue and provides for estimated marketing and sales incentive costs when products are shipped to dealers and distributors pursuant to their order, the price is fixed and collection is reasonably assured. Shipping and handling costs are recorded as a component of costs of goods sold and shipping charges to the dealers are recorded as revenue at the time products are shipped.
	Return allowances for parts and accessories are recorded as a reduction of revenue when the products are sold based on the company’s return allowance program and historical experience.
	Sales tax collected from customers is remitted to the appropriate taxing jurisdictions and is excluded from sales revenue as the Company considers itself a pass-through conduit for collecting and remitting sales taxes.
Marketing and Sales Incentive Costs	Marketing and Sales Incentive Costs
	At the time product revenue is recognized the Company provides for various marketing and sales incentive costs that are offered to its dealers and consumers. Examples of these costs, which are recognized as a reduction of revenue when the products are sold, include dealer and consumer rebates, dealer floor plan financing assistance and other incentive and promotion programs. Generally, the Company records provisions for these marketing programs at the later of when the revenue is recognized or when the sales incentive or marketing program is approved and communicated for products previously shipped. Sales incentives that involve a free product or service delivered to the consumer are recorded as a component of cost of goods sold. The Company estimates the costs of these various incentive and marketing programs at the time of sale or subsequently when programs are approved and communicated based on historical experience. To the extent current experience differs with previous estimates the accrued liability for marketing and sales incentives is adjusted accordingly.
Dealer Holdback	Dealer Holdback
	The Company records a dealer holdback program liability at the time certain products are shipped to its dealers. If the products subject to the holdback program are sold within the program time period, the Company refunds a portion of the original sale price, referred to as dealer holdback, to the dealer within the program time period and refunds any remaining balances to its dealers when the program time periods end. The Company’s dealer holdback program liability, included within accounts payable, was $19,751,000 and $19,448,000 as of March 31, 2015 and 2014, respectively.
Research and Development	Research and Development

Advertising	Advertising
	The Company expenses advertising costs as incurred, except for cooperative advertising obligations arising related to the sale of the Company’s products to its dealers. The estimated cost of cooperative advertising, which the dealer is required to support, is recorded as marketing expense at the time the product is sold. Cooperative advertising was $3,566,000, $3,440,000 and $3,556,000 in fiscal 2015, 2014 and 2013, respectively. Total advertising expense, including cooperative advertising, was $18,588,000, $17,562,000 and $17,232,000 in fiscal 2015, 2014 and 2013, respectively.
Net Earnings Per Share	Net Earnings Per Share
	The Company’s diluted weighted average shares outstanding include common shares and common share equivalents relating to stock options, when dilutive. Options to purchase 156,432 shares of common stock with weighted average exercise prices of $44.14 were outstanding during fiscal 2015 but were excluded from the computation of common share equivalents because they were anti-dilutive. No options outstanding were excluded from the computation of common share equivalents during fiscal 2014. Options to purchase 70,470 shares of common stock with weighted average exercise prices of $43.79 were outstanding during fiscal 2013 but were excluded from the computation of common share equivalents because they were anti-dilutive.
