Nature of Operations and Accounting Policies	'
	1	Nature of Operations and Accounting Policies
	Nature of Operations - Thor Industries, Inc. was founded in 1980 and, through its subsidiaries (the “Company”), manufactures a wide range of recreational vehicles (“RVs”) at various manufacturing facilities located primarily in Indiana and Ohio. These products are sold to independent dealers primarily throughout the United States and Canada. Unless the context otherwise requires or indicates, all references to “Thor”, the “Company”, “we”, “our” and “us” refer to Thor Industries, Inc. and its subsidiaries.
	The Company’s core business activities are comprised of two distinct operations, which include the design, manufacture and sale of both towable recreational vehicles and motorized recreational vehicles. Accordingly, the Company has presented segment financial information for these two segments in Note 4 to the Condensed Consolidated Financial Statements. See Note 3, “Discontinued Operations,” in the Notes to the Condensed Consolidated Financial Statements for a description of the Company’s bus operations which were sold during the three months ended October 31, 2013. Accordingly, the accompanying financial statements (including footnote disclosures unless otherwise indicated) reflect these operations as discontinued operations apart from the Company’s continuing recreational vehicle operations.
	The July 31, 2013 amounts are derived from the annual audited financial statements. The interim financial statements are unaudited. In the opinion of management, all adjustments (which consist of normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented have been made. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2013. Due to seasonality within the recreational vehicle industry, the extrapolated results of operations for the six months ended January 31, 2014 are not necessarily indicative of the results for the full year.
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Key estimates include reserves for inventory, incurred but not reported medical claims, warranty claims, recall liabilities, workers’ compensation claims, vehicle repurchases, uncertain tax positions, product and non-product litigation and fair value determinations made for both intangible assets acquired and asset impairment assessments. The Company bases its estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. The Company believes that such estimates are made using consistent and appropriate methods. Actual results could differ from these estimates.

	2	Acquisitions
	On October 31, 2013, the Company closed on an Asset Purchase Agreement with Bison Coach, LLC for the acquisition of its net operating assets for cash consideration of $16,718, subject to adjustment, which was funded entirely from the Company’s cash on hand. The purchase price adjustment is based on a final determination of net assets and is expected to be finalized in the third quarter of fiscal 2014. As a result of the purchase, the Company formed a new entity, Bison Coach (“Bison”), which operates as an independent operation in the same manner as the Company’s other existing recreational vehicle subsidiaries and is aggregated within the Company’s towable recreational vehicle reportable segment. The Company purchased the net assets of Bison Coach, LLC to supplement its existing product offerings with Bison’s equestrian products with living quarters.
	The following table summarizes the fair values assigned to the Bison net assets acquired, which are based on internal and independent external valuations:
	Current assets		$      3,995
	Property, plant and equipment		625
	Dealer network		7,400
	Trademarks		1,800
	Backlog		140
	Goodwill		6,660
	Current liabilities		-3,902
	Total fair value of net assets acquired		$    16,718
	During the fiscal quarter ended January 31, 2014, the preliminary values of the dealer network and the trademarks were decreased by $400 and $200, respectively, and goodwill increased by $600 accordingly, as a result of finalizing the valuations for these intangible assets.
	On the acquisition date, amortizable intangible assets had a weighted average useful life of 13.3 years. The dealer network was valued based on the Discounted Cash Flow Method and will be amortized on an accelerated cash flow basis over 12 years. The trademarks were valued on the Relief from Royalty Method and will be amortized on a straight line basis over 20 years. Backlog was valued based on the Discounted Cash Flow Method and was amortized on a straight line basis over 6 weeks. Goodwill is deductible for tax purposes.
	On August 30, 2013, the Company closed on an Asset Purchase Agreement with Livin’ Lite Corp. for the acquisition of its net operating assets for aggregate cash consideration of $16,769, net of cash acquired, which was funded entirely from the Company’s cash on hand. As a result of the purchase, the Company formed a new entity, Livin’ Lite RV, Inc. (“Livin’ Lite”), which continues to operate as an independent operation in the same manner as the Company’s existing recreational vehicle subsidiaries and is aggregated within the Company’s towable recreational vehicle reportable segment. The Company purchased the Livin’ Lite Corp. operating assets to expand its recreational vehicle market share and complement its existing brands with Livin’ Lite’s advanced lightweight product offerings.
	The following table summarizes the fair values assigned to the Livin’ Lite net assets acquired, which are based on internal and independent external valuations:
	Cash		$        247
	Other current assets		3,626
	Property, plant and equipment		137
	Dealer network		3,200
	Trademarks		1,500
	Design technology assets		1,100
	Non-compete agreements		130
	Backlog		110
	Goodwill		9,113
	Current liabilities		-2,147
	Total fair value of net assets acquired		17,016
	Less cash acquired		-247
	Total cash paid for acquisition, less cash acquired		$    16,769
	On the acquisition date, amortizable intangible assets had a weighted average useful life of 10.2 years. The dealer network was valued based on the Discounted Cash Flow Method and will be amortized on an accelerated cash flow basis over 8 years. The trademarks were valued on the Relief from Royalty Method and will be amortized on a straight line basis over 20 years. The design technology assets were valued on the Relief from Royalty Method and will be amortized on a straight line basis over 5 years. The non-compete agreements and backlog were both valued based on the Discounted Cash Flow Method and will be amortized on a straight line basis over 2 years and 6 weeks, respectively. Goodwill is deductible for tax purposes.
	On December 20, 2012, the Company acquired the Federal Coach (“Federal Coach”) bus operation assets from Forest River, Inc. for cash consideration of $6,804. The fair value of the net assets acquired included inventory of $804, property and equipment of $630, certain liabilities of $225, goodwill of $4,495, and amortizable intangible assets consisting of trademarks of $670, dealer network of $410 and backlog of $20. The Federal Coach bus operation assets were utilized at the Champion Bus facility to produce buses under the Federal Coach name. The related assets and liabilities were sold as of October 20, 2013 and the results of operations since acquisition are included in discontinued operations as discussed in Note 3 to the Condensed Consolidated Financial Statements.
	On October 3, 2012, the Company closed on an Asset Purchase Agreement with Krystal Infinity, LLC dba Krystal Enterprises (“Krystal”) for the acquisition of Krystal’s bus operation assets for cash consideration of $3,914. The fair value of the net assets acquired included inventory of $915, property and equipment of $331, goodwill of $768 and amortizable intangible assets consisting of trademarks of $1,000 and dealer network of $900. The Krystal bus operation assets were utilized at the ElDorado Kansas facility to produce buses under the Krystal name. The related assets and liabilities were sold as of October 20, 2013 and the results of operations since acquisition are included in discontinued operations as discussed in Note 3 to the Condensed Consolidated Financial Statements.

Discontinued Operations	'
	3	Discontinued Operations
	On July 31, 2013, the Company entered into a Stock Purchase Agreement (“SPA”) to sell its bus business to Allied Specialty Vehicles, Inc. (“ASV”) for cash of $100,000, subject to closing adjustments for changes in the net assets to be sold from April 30, 2013 to the closing date. The Company’s bus business, which manufactured and sold transit and shuttle buses, included the operations of Champion Bus Inc., General Coach America, Inc., Goshen Coach, Inc., ElDorado National Kansas, Inc. and ElDorado National California, Inc. This divestiture will allow the Company to focus on the strategic development and growth of its core recreational vehicle business.
	The sale was completed as of October 20, 2013 and the Company received $100,000 on October 21, 2013. Under the terms of the SPA, the total cash consideration to be received was subject to adjustment based on changes in the carrying value of the net assets of the bus business between April 30, 2013 and October 20, 2013. The amount of the final net asset adjustment was determined through the completion of a post-close audit during the second quarter of fiscal 2014. Based on the final agreed-upon carrying value of the bus business net assets sold as of October 20, 2013, an additional $5,043 is due from ASV, representing the increase in bus net assets since April 30, 2013. The $5,043 is reflected in other accounts receivable as of January 31, 2014 in the Condensed Consolidated Balance Sheets and was received subsequent to that date. During the second quarter of fiscal 2014, the Company also received the $2,323 of bus cash which was transferred to ASV at the time of the close of the sale and was reflected in other accounts receivable as of October 31, 2013.
	The Company has recorded a pre-tax gain of $7,079 as a result of the sale. This amount includes a $746 unfavorable adjustment recorded during the second quarter of fiscal 2014 based on the completion of the post-close audit. The results of operations for the bus business, including the gain on the sale of the bus business, have been reported as discontinued operations in the Condensed Consolidated Statements of Income and Comprehensive Income for all periods presented.
	On April 30, 2013, the Company sold the assets held and used in the conduct of its ambulance product line (excluding the plant utilized in ambulance production and certain other excluded assets) for a final price of $12,051. There was no gain or loss recognized on the sale. Discontinued operations for fiscal 2013 include the results of the ambulance product line.
	The following table summarizes the results of discontinued operations:
			Three Months Ended				Six Months Ended
			January 31,				January 31,
	Discontinued Operations:		2014		2013		2014		2013
	Net sales		$	–	$	104,995	$	83,903	$	219,183

	Income (loss) from discontinued operations, net of taxes		$	-1,026	$	877	$	3,688	$	3,116
	Operating income (loss) of discontinued operations during the three months ended January 31, 2014 reflects expenses incurred directly related to the former bus operations including adjustments to liabilities retained by the Company under the SPA for bus product liability and worker’s compensation claims occurring prior to the closing date of the sale.
	As a result of the sale of the bus business, and in accordance with the SPA, the Company is no longer the primary obligor to the taxing authorities for bus operations in certain states. As a result, the Company eliminated the reserves associated with certain uncertain tax positions resulting in a net tax benefit of $1,883 which is reflected within discontinued operations. Under the terms of the sale, the Company has agreed to indemnify ASV for any claims made by the taxing authorities after the date of sale for these uncertain tax positions but does not expect future losses under this guarantee to be material.
	The following is a summary of the assets and liabilities of discontinued operations, excluding cash, which were held for sale as of July 31, 2013:
	Accounts and other receivable, net		$	29,894
	Inventories, net of LIFO reserve of $9,683			61,800
	Property, plant and equipment, cost			50,985
	Accumulated depreciation, property, plant and equipment			-21,422
	Goodwill			5,559
	Other intangibles, net			3,743
	Deferred income taxes and other assets			2,540
	Deferred compensation plan assets			3,407
	Assets of discontinued operations		$	136,506
	Accounts payable		$	23,427
	Accrued compensation and related items			3,130
	Product warranties			3,891
	Deferred income taxes and other liabilities			1,252
	Deferred compensation plan liabilities			3,407
	Liabilities of discontinued operations		$	35,107
	In accordance with the SPA, the Company will retain the costs and liabilities associated with the bus business product liability and worker’s compensation claims for any occurrence prior to the closing date of the sale. Therefore, these reserves are not included in the liabilities of discontinued operations on the Condensed Consolidated Balance Sheet as of July 31, 2013.

	Acquisitions of towables businesses			15,773
	Balance at January 31, 2014		$	253,876
	All of the goodwill resides in the towables recreational vehicle segment.
	Goodwill is not subject to amortization, but instead is reviewed for impairment by applying a fair-value based test to the Company’s reporting units on an annual basis as of April 30, or more frequently if events or circumstances indicate a potential impairment. The Company’s reporting units are the same as its operating segments, which are identified in Note 4 to the Condensed Consolidated Financial Statements. Fair values are determined by a discounted cash flow model and a market approach, when appropriate. These estimates are subject to significant management judgment including the determination of many factors such as sales growth rates, gross margin patterns, cost growth rates, comparable companies, terminal value assumptions and discount rates and therefore largely represent Level 3 inputs as defined by ASC 820. Changes in these estimates can have a significant impact on the determination of cash flows and fair value and could potentially result in future material impairments.
	During the first quarter of fiscal 2014, the Company determined it was more likely than not that certain long-lived assets, consisting of certain RV facilities, will be sold or altered before the end of their previously estimated useful life. Therefore, the Company performed impairment assessments over these facilities using Level 3 inputs as defined by ASC 820 to determine whether an impairment exists. As a result of these assessments, a non-cash impairment charge of $710 was recognized in the quarter ended October 31, 2013.

	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (i.e., 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. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:
	Level 1 - Quoted prices in active markets for identical assets or liabilities.
	Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, 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 only Company investments or liabilities carried at fair value in the financial statements are its investments in auction rate securities (“ARS”) – measured with Level 3 inputs, and in other securities (primarily in mutual funds) held for the benefit of certain employees of the Company as part of a deferred compensation plan - measured with Level 1 inputs. ARS balances of $0 and $666 and deferred compensation plan asset balances of $8,205 and $7,000 (excluding $3,407 at July 31, 2013 related to discontinued operations) were recorded as of January 31, 2014 and July 31, 2013, respectively, as components of other assets in the Condensed Consolidated Balance Sheets. An equal and offsetting accrued liability was also recorded in regards to the deferred compensation plan as a component of other long-term liabilities in the Condensed Consolidated Balance Sheets. Changes in the fair value of the plan assets and the related deferred liability are both reflected in the Condensed Consolidated Statements of Income and Comprehensive Income.
	The following table provides a reconciliation of the beginning and ending balance for the assets measured at fair value using significant unobservable inputs (Level 3 financial assets):

	The Company generally provides retail customers of its products with a one-year warranty covering defects in material or workmanship, with longer warranties of up to five years on certain structural components. The Company records a liability based on its best estimate of the amounts necessary to settle future and existing claims on products sold as of the balance sheet date. Factors used in estimating the warranty liability include a history of units sold, existing dealer inventory, average cost incurred and a profile of the distribution of warranty expenditures over the warranty period. Management believes that the warranty reserves are adequate. However, actual claims incurred could differ from estimates, requiring adjustments to the reserves. Warranty reserves are reviewed and adjusted as necessary on at least a quarterly basis.

Provision for Income Taxes	'
	12	Provision for Income Taxes
	The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current period and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Company’s financial statements or tax returns. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Fluctuations in the actual outcome of these tax consequences could materially impact our financial position or results of operations.
	The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as the probability of various possible outcomes must be determined. These uncertain tax positions are re-evaluated on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Such a change in recognition or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision.
	It is the Company’s policy to recognize interest and penalties accrued relative to unrecognized tax benefits in income tax expense. For the six months ended January 31, 2014, the Company released $5,683 of gross uncertain tax positions and related interest and penalties recorded at July 31, 2013 related to the settlement of uncertain tax positions, which resulted in a net income tax benefit of $2,632. The Company accrued $586 in interest and penalties related to the remaining uncertain tax positions recorded at July 31, 2013. For the three months ended January 31, 2014, the Company released $4,041 of gross uncertain tax positions and related interest and penalties recorded at July 31, 2013 related to the settlement of uncertain tax positions, which resulted in a net income tax benefit of $1,624, and accrued $291 in interest and penalties.
	The overall effective income tax rate for the three months ended January 31, 2014 was 28.0% compared with 22.2% for the three months ended January 31, 2013. The overall effective income tax rate for the six months ended January 31, 2014 was 31.6% compared with 30.4% for the six months ended January 31, 2013. The primary reason for the increase in the overall effective income tax rates for the three months and six months ended January 31, 2014 was the retroactive reinstatement of the Federal research and development credit and other credits that occurred during the fiscal 2013 periods. In addition, the effective income tax rates for both the fiscal 2013 and 2014 periods were favorably impacted from the settlement of certain uncertain tax benefits.
	The Company anticipates a decrease of $3,660 in unrecognized tax benefits, and $895 in accrued interest and penalties related to these unrecognized tax benefits, within the next 12 months from expected settlements or payments of uncertain tax positions and lapses of the applicable statutes of limitations. In addition, the Company is currently in the process of pursuing a variety of settlement alternatives with taxing authorities. It is reasonably possible that some of these settlements could be finalized in the next 12 months. If these settlements are finalized within the next 12 months, the gross unrecognized tax benefits may decrease between $900 and $6,500 and related accrued interest and penalties may decrease between $400 and $3,800. It is reasonably possible that some of these settlements will result in cash payments by the Company. Actual results may differ materially from these estimates.
	Generally, fiscal years 2010, 2011 and 2012 remain open for federal, state and foreign income tax purposes. The Company and its subsidiaries file a consolidated U.S. federal income tax return and multiple state income tax returns. The federal returns are subject to examination by taxing authorities for all years after fiscal 2009. The Company is currently under IRS audit for fiscal year 2011. The Company is also being audited by the state of California for tax years ended July 31, 2007 and July 31, 2008 and by the state of Indiana for tax years ended July 31, 2008, 2009 and 2010. The Company believes it has adequately reserved for its exposure to additional payments for uncertain tax positions related to its federal, California and Indiana income tax audits in its liability for unrecognized tax benefits.

Contingent Liabilities and Commitments	'
	13	Contingent Liabilities and Commitments
	The Company is contingently liable under terms of repurchase agreements with financial institutions providing inventory financing for certain dealers of certain of its products. These arrangements, which are customary in the industry, provide for the repurchase of products sold to dealers in the event of default by the dealer on the agreement to pay the financial institution. The repurchase price is generally determined by the original sales price of the product and pre-defined curtailment arrangements. The Company typically resells the repurchased product at a discount from its repurchase price. The risk of loss from these agreements is spread over numerous dealers. In addition to the guarantee under these repurchase agreements, we may also be required to repurchase inventory relative to dealer terminations in certain states in accordance with state laws or regulatory requirements. The repurchase activity related to dealer terminations in certain states has been insignificant in relation to our repurchase obligation with financial institutions.
	The Company’s total commercial commitment under standby repurchase obligations on dealer inventory financing at January 31, 2014 is $1,165,309. The commitment term is primarily up to eighteen months.
	The Company accounts for the guarantee under repurchase agreements of dealers’ financing by deferring a portion of the related product sale that represents the estimated fair value of the guarantee at inception. The estimated fair value takes into account an estimate of the losses that may be incurred upon resale of any repurchases. This estimate is based on recent historical experience supplemented by the Company’s assessment of current economic and other conditions affecting its dealers. This deferred amount is included in the repurchase and guarantee reserve balances of $4,177 and $3,778 as of January 31, 2014 and July 31, 2013, respectively, which are included in other current liabilities on the Condensed Consolidated Balance Sheets.
	The table below reflects losses incurred under repurchase agreements in the periods noted. The Company believes that any future losses under these agreements will not have a significant effect on the Company’s consolidated financial position, results of operations or cash flows.

	Legal Matters
	The Company is involved in certain litigation arising out of its operations in the normal course of its business, most of which is based upon state “lemon laws”, warranty claims and vehicle accidents (for which the Company carries insurance above a specified self-insured retention or deductible amount). The outcomes of legal proceedings and claims brought against the Company are subject to significant uncertainty. There is significant judgment required in assessing both the probability of an adverse outcome and the determination as to whether an exposure can be reasonably estimated. In management’s opinion, the ultimate disposition of any current legal proceedings or claims against the Company will not have a material effect on the Company’s financial condition, operating results or cash flows, except that an adverse outcome in a significant litigation matter could have a material effect on the operating results of a particular reporting period.

The Committee approved additional awards that were granted in fiscal 2014 related to fiscal year 2013 performance. The employee restricted stock units vest, and shares of common stock will be issued, in equal installments on the first, second and third anniversaries of the date of grant. In fiscal 2013 and again in fiscal 2014, the Nominating and Governance Committee of the Board awarded restricted stock units to Board members that will vest, and shares of common stock will be issued, on the first anniversary of the date of the grant. Total expense recognized in the six months ended January 31, 2014 and January 31, 2013 for restricted stock unit awards and other stock based compensation was $2,648 and $1,312, respectively, which included $480 and $104, respectively, related to discontinued operations.
	For the restricted stock units that vested during the six months ended January 31, 2014, a certain portion of the vested shares awarded were withheld to cover the recipients’ estimated withholding taxes, which was then paid by the Company on their behalf.

	Nature of Operations - Thor Industries, Inc. was founded in 1980 and, through its subsidiaries (the “Company”), manufactures a wide range of recreational vehicles (“RVs”) at various manufacturing facilities located primarily in Indiana and Ohio. These products are sold to independent dealers primarily throughout the United States and Canada. Unless the context otherwise requires or indicates, all references to “Thor”, the “Company”, “we”, “our” and “us” refer to Thor Industries, Inc. and its subsidiaries.
	The Company’s core business activities are comprised of two distinct operations, which include the design, manufacture and sale of both towable recreational vehicles and motorized recreational vehicles. Accordingly, the Company has presented segment financial information for these two segments in Note 4 to the Condensed Consolidated Financial Statements. See Note 3, “Discontinued Operations,” in the Notes to the Condensed Consolidated Financial Statements for a description of the Company’s bus operations which were sold during the three months ended October 31, 2013. Accordingly, the accompanying financial statements (including footnote disclosures unless otherwise indicated) reflect these operations as discontinued operations apart from the Company’s continuing recreational vehicle operations.
	The July 31, 2013 amounts are derived from the annual audited financial statements. The interim financial statements are unaudited. In the opinion of management, all adjustments (which consist of normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented have been made. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2013. Due to seasonality within the recreational vehicle industry, the extrapolated results of operations for the six months ended January 31, 2014 are not necessarily indicative of the results for the full year.
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Key estimates include reserves for inventory, incurred but not reported medical claims, warranty claims, recall liabilities, workers’ compensation claims, vehicle repurchases, uncertain tax positions, product and non-product litigation and fair value determinations made for both intangible assets acquired and asset impairment assessments. The Company bases its estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. The Company believes that such estimates are made using consistent and appropriate methods. Actual results could differ from these estimates.
