NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Nature of Operations - Thor Industries, Inc. was founded in 1980 and, through its subsidiaries (the “Company”), manufactures a wide range of recreation vehicles (“RVs”) and small and mid-size buses at various manufacturing facilities across the United States. These products are sold to independent dealers and municipalities 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 three distinct operations, which include the design, manufacture and sale of towable recreation vehicles, motorized recreation vehicles and buses. Accordingly, the Company has presented segment financial information for these three segments in Note 3 to the Condensed Consolidated Financial Statements.

The July 31, 2012 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, 2012. Due to seasonality within the recreation vehicle industry, the results of operations for the nine months ended April 30, 2013 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, recalls, workers’ compensation claims, vehicle repurchases, uncertain tax positions, product and non-product litigation and fair value determinations made in 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.

Accounting Pronouncements - In September 2011, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2011-08, “Testing Goodwill for Impairment”, to simplify how entities test goodwill for impairment. This guidance permits an entity to assess qualitative factors to determine whether it is more likely than not (defined as more than fifty percent) that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the current two-step goodwill impairment test. The two-step goodwill impairment test that begins with estimating the fair value of the reporting unit will only be required if the entity determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. ASU No. 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. The adoption of this guidance did not have a material impact on the Company’s Condensed Consolidated Financial Statements.

Acquisition of Bus Businesses - On September 17, 2012, the Company entered into 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 acquisition closed on October 3, 2012. 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 Company purchased the Krystal bus operation assets to expand its bus business and achieve cost efficiencies. The Krystal bus operation assets are utilized at the ElDorado Kansas facility to produce buses under the Krystal name.

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 Company purchased the Federal Coach bus operation assets to expand its bus business and achieve cost efficiencies. The Federal Coach bus operation assets are utilized at the Champion Bus facility to produce buses under the Federal Coach name.

Disposition of Ambulance Net Assets - 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 $12,331, subject to certain adjustments. The sale price of $12,331 is reflected as a component of Other Accounts Receivable in the Condensed Consolidated Balance Sheets as of April 30, 2013 and will be fully realized in the fourth quarter of fiscal year 2013. See Note 5 for discussion of impairment charges. There was no gain or loss recognized on the sale.

The Company excludes stock options and unvested restricted stock and restricted stock units that have an antidilutive effect from its calculation of weighted average shares outstanding assuming dilution. At April 30, 2013 and 2012, the Company had 36,264 and 400,000, respectively, of antidilutive stock options and unvested restricted stock and restricted stock units outstanding which were excluded from this calculation.

The Company has three reportable segments: (1) towable recreation vehicles, (2) motorized recreation vehicles and (3) buses. The towable recreation vehicle reportable segment consists of product lines from the following operating segments that have been aggregated: Airstream, CrossRoads, Dutchmen, Keystone and Heartland. The motorized recreation vehicle reportable segment consists of product lines from the following operating segments that have been aggregated: Airstream and Thor Motor Coach. The bus reportable segment consists of the following operating segments that have been aggregated: Champion Bus, ElDorado California, ElDorado Kansas and Goshen Coach (which included ambulance sales through April 30, 2013). Intersegment sales are not material.

Major classifications of inventories are:

Of the $271,385 and $219,863 of inventory at April 30, 2013 and July 31, 2012, all but $27,011 and $36,887, respectively, at certain subsidiaries were valued on a last-in, first-out basis. The $27,011 and $36,887 of inventory were valued on a first-in, first-out method.

The components of amortizable intangible assets are as follows:

Dealer networks are primarily being amortized on an accelerated cash flow basis. Non-compete agreements, trademarks, and design technology and other intangibles are amortized on a straight-line basis.

Estimated annual amortization expense is as follows:

The change in carrying value in goodwill from July 31, 2012 to April 30, 2013 is as follows:

Goodwill by reportable segment is as follows:

In April 2013, the Company determined that it was more likely than not that certain long-lived assets associated with the Company’s ambulance product line would be sold before the end of their previously estimated useful life. This was determined to be a triggering event and an impairment assessment relative to those assets was performed. Based on the assessment, the Company determined that the carrying amount of the assets would not be recoverable from future cash flows and as a result, a non-cash impairment charge of $4,715 related to certain amortizable intangible assets within the Company’s bus reportable segment was recorded.

The Company performed an interim goodwill impairment assessment relative to the goodwill associated with the bus reporting unit which historically included the ambulance product line. Based on the assessment, the Company determined that the fair value of the reporting unit was less than the carrying value and therefore performed the second step of the goodwill impairment assessment, which requires estimating the fair values of the reporting unit’s net identifiable assets and calculating the implied fair value of goodwill. As of the last annual impairment assessment, the fair value of this reporting unit exceeded carrying value by 15%. Recent performance of this reporting unit, particularly its margin percentage was below previous forecasts and resulted in a reduction of the five year forecast. The fair value of the reporting unit was determined by a discounted cash flow model and market approach, consistent with its last annual impairment assessment as more fully described below. The implied fair value of goodwill was determined to be zero and, therefore, recorded goodwill was impaired and a non-cash impairment charge of $6,810 was recognized in the third quarter of fiscal year 2013. The goodwill impairment was primarily a result of lower forecasted margins and increased working capital requirements within the reporting unit. These non-cash impairment charges totaling $11,525 are included in Impairment of Goodwill and Intangible Assets on the Condensed Consolidated Statements of Operations and Comprehensive Income.

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 3 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. The Company completed its annual impairment review as of April 30, 2013 and April 30, 2012; no additional impairment of goodwill was identified, other than as described above in our interim assessment which was required as a result of a triggering event.

One dealer, FreedomRoads, LLC (“FreedomRoads”), accounted for 16% of the Company’s consolidated recreation vehicle net sales for the nine months ended April 30, 2013 and 14% of its consolidated net sales for the nine months ended April 30, 2013. This dealer also accounted for 15% of the Company’s consolidated trade accounts receivable at April 30, 2013 and 20% at July 31, 2012. The loss of this dealer could have a significant effect on the Company’s business. Two dealers accounted for 22% of the Company’s bus net sales for the nine months ended April 30, 2013. The loss of either of these dealers could have a significant effect on the Company’s bus business.

On January 15, 2009, the Company entered into a Credit Agreement (the “First Credit Agreement”) with Stephen Adams, in his individual capacity, and Stephen Adams and his successors, as trustee under the Stephen Adams Living Trust (the “Trust” and together with each of the foregoing persons, the “Borrowers”), pursuant to which the Company loaned $10,000 to the Borrowers (the “First Loan”). The Borrowers own, directly or indirectly, a controlling interest in FreedomRoads Holding Company, LLC (“FreedomRoads Holding”), the parent company of FreedomRoads, the Company’s largest dealer. Pursuant to the terms of the First Credit Agreement, the Borrowers agreed to use the proceeds of the First Loan solely to make an equity contribution to FreedomRoads Holding to enable FreedomRoads Holding or its subsidiaries to repay its principal obligations under floor plan financing arrangements with third parties in respect of products of the Company and its subsidiaries.

An early payment of $6,000 on the First Loan was received by the Company in the quarter ended January 31, 2013. The remaining principal amount of $4,000 on the First Loan is payable in full on January 15, 2014 and bears interest at a rate of 12% per annum. Interest was payable in kind for the first year, and was capitalized as part of the long-term note receivable, and is payable in cash on a monthly basis thereafter. All principal and interest payments due to date have been paid in full and principal payments on the First Loan are classified as investing activities in the Condensed Consolidated Statements of Cash Flows.

9

On January 30, 2009, the Company entered into a second Credit Agreement (the “Second Credit Agreement”) with the Borrowers pursuant to which the Company loaned an additional $10,000 to the Borrowers (the “Second Loan”). Pursuant to the terms of the Second Credit Agreement, the Borrowers agreed to use the proceeds of the Second Loan solely to make an equity contribution to FreedomRoads Holding to be used by FreedomRoads Holding or its subsidiaries to purchase the Company’s products. As a result, principal payments received on the Second Loan are classified as operating activities in the Condensed Consolidated Statements of Cash Flows. The final principal and interest payments on the Second Loan were received in fiscal 2012.

On December 22, 2009, the Company entered into a third Credit Agreement (the “Third Credit Agreement”) with Marcus Lemonis, Stephen Adams, in his individual capacity, and Stephen Adams and his successors, as trustee under the Trust (each of the foregoing persons, on a joint and several basis, the “Third Loan Borrowers”), pursuant to which the Company loaned $10,000 to the Third Loan Borrowers (the “Third Loan”). The Third Loan Borrowers own, directly or indirectly, a controlling interest in FreedomRoads Holding, the indirect parent company of FreedomRoads. Pursuant to the terms of the Third Credit Agreement, the Third Loan Borrowers agreed to use the proceeds of the Third Loan solely to provide a loan to one of FreedomRoads Holding’s subsidiaries which would ultimately be contributed as equity to FreedomRoads to be used for working capital purposes.

On December 12, 2012, the Company, the First Loan Borrowers and the Third Loan Borrowers entered into an agreement to extend the maturity date of $6,000 due under the Third Loan from December 22, 2014 to August 30, 2015, in exchange for early payment of $6,000 on the First Loan on or before January 15, 2013. This early payment was received by the Company in the quarter ended January 31, 2013. The remaining original principal amount of the Third Loan, as amended, is payable on the following dates in the following amounts: December 31, 2013 - $1,100; December 22, 2014 - $1,400 and August 30, 2015 - $6,000. The principal amount of the Third Loan bears interest at a rate of 12% per annum. Interest is payable, at the option of the Third Loan Borrowers, either in cash or in-kind at each calendar quarter end from March 31, 2010 through September 30, 2011, and thereafter in cash quarterly in arrears from December 31, 2011 through the maturity date. The Third Loan Borrowers opted to pay the interest due at each quarter end from March 31, 2010 to September 30, 2011 in-kind and it was capitalized as part of the long-term note receivable. All payments of principal and interest due to date have been paid in full and principal payments received on the Third Loan are classified as investing activities in the Condensed Consolidated Statements of Cash Flows.

The First Credit Agreement, the Second Credit Agreement and the Third Credit Agreement each contain customary representations and warranties, affirmative and negative covenants, events of default and acceleration provisions for loans of this type. As required by the credit agreements, the Company receives on a quarterly basis financial information from the Borrowers and the Third Loan Borrowers and from the companies in which the Borrowers and the Third Loan Borrowers have significant ownership interests, including FreedomRoads Holding. This financial information is reviewed and evaluated as to any changes in the overall credit quality of the Borrowers and the Third Loan Borrowers. Based on the current credit review, the Company does not consider the receivables impaired or requiring an allowance for credit losses.

In connection with the First Loan, the Borrowers caused FreedomRoads Holding and its subsidiaries (collectively, the “FR Dealers”), to enter into an agreement pursuant to which the FR Dealers agreed to purchase additional recreation vehicles from the Company’s subsidiaries. The term of this agreement, as subsequently amended in connection with the Second Loan and the Third Loan, continues until December 22, 2029 unless earlier terminated in accordance with its terms.

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 assets 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 $1,032 and $1,405 and deferred compensation plan asset balances of $9,697 and $8,970 were recorded as of April 30, 2013 and July 31, 2012, 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 Accrued 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 income.

The ARS underlying assets are primarily student loans which are substantially backed by the federal government. While the ARSs are subject to periodic settlements via open auctions, the Company may need to wait until the final maturity of the underlying loans to realize the full value of the ARS.

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.

Changes in our product warranty reserves are as follows:

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. 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. The 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 nine months ended April 30, 2013, the Company released $8,730 of gross uncertain tax benefit reserves and related interest and penalties recorded at July 31, 2012 related to the effective settlement of certain uncertain tax benefits and statute of limitation expirations, which resulted in a net income tax benefit of $4,407. The Company accrued $907 in interest and penalties related to the remaining uncertain tax benefits recorded at July 31, 2012 and recorded additional uncertain tax benefit reserves of $340 related to previous tax periods. For the three months ended April 30, 2013, the Company released $3,916 of gross uncertain tax benefit reserves recorded at July 31, 2012 which resulted in a net income tax benefit of $2,593, recorded $118 of additional uncertain tax benefit reserves related to previous tax periods and accrued $210 in interest and penalties.

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 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 fully reserved for its exposure to additional payments for uncertain tax positions related to its California and Indiana income tax returns in its liability for unrecognized tax benefits.

The overall effective income tax rate for the three months ended April 30, 2013 was 30.1% compared with 32.5% for the three months ended April 30, 2012. The effective income tax rate for the three months ended April 30, 2013 was favorably impacted by the settlement of certain uncertain tax benefits. The effective income tax rate for the three months ended April 30, 2012 was also favorably impacted, although to a lesser extent, by certain tax return to provision adjustments.

The overall effective income tax rate for the nine months ended April 30, 2013 was 30.3% compared with 34.1% for the nine months ended April 30, 2012. The effective income tax rate for the nine months ended April 30, 2013 was favorably impacted by the effective settlement of certain uncertain tax benefits. The Company also recorded a tax benefit in the nine months ended April 30, 2013 from the retroactive reinstatement of the federal research and development credit and other credits that were enacted on January 2, 2013. The effective income tax rate for the nine months ended April 30, 2012 was also favorably impacted, although to a lesser extent, by certain tax return to provision adjustments.

12

The Company anticipates a decrease of approximately $3,300 in unrecognized tax benefits, and $750 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 $1,100 and $6,900 and related accrued interest and penalties may decrease between $600 and $2,700. It is reasonably possible that some of these settlements will result in cash payments by the Company. Actual results may differ from these estimates.

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, the Company also provides limited dealer inventory financing guarantees to certain of its dealers.

The Company’s principal commercial commitments under repurchase agreements and dealer inventory financing guarantees at April 30, 2013 are summarized in the following chart:

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. The estimated fair value takes into account an estimate of the losses that will 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 our dealers.

This deferred amount is included in the repurchase and guarantee reserve balances of $4,322 and $3,150 as of April 30, 2013 and July 31, 2012, respectively, which are included in Other Current Liabilities on the Condensed Consolidated Balance Sheets. These reserves do not include any amounts for dealer inventory financing guarantees as the Company does not currently expect any losses from such guarantees and believes the fair value of these guarantees is immaterial.

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.

The Company obtains certain vehicle chassis from automobile manufacturers under converter pool agreements. These agreements generally provide that the manufacturer will supply chassis at the Company’s various production facilities under the terms and conditions set forth in the agreement. The manufacturer does not transfer the certificate of origin to the Company and, accordingly, the Company accounts for the chassis as consigned, unrecorded inventory. Upon being put into production, the Company becomes obligated to pay the manufacturer for the chassis. Chassis are typically converted and delivered to customers within 90 days of delivery. If the chassis are not converted within 90 days of delivery to the Company, the Company generally purchases the chassis and records the inventory. At April 30, 2013, vendor supplied chassis on hand accounted for as consigned, unrecorded inventory was $10,466. In addition to this consigned inventory, $6,295 of chassis provided by customers were located at the Company’s production facilities at April 30, 2013, pending further manufacturing. The Company never purchases these chassis and does not include their cost in its billings to the customer for the completed unit.

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.

FEMA Trailer Formaldehyde Litigation

Beginning in 2006, a number of lawsuits were filed against numerous trailer and manufactured housing manufacturers, including complaints against the Company. The complaints were filed in various state and federal courts throughout Louisiana, Alabama, Texas and Mississippi on behalf of Gulf Coast residents who lived in travel trailers, park model trailers and manufactured homes provided by the Federal Emergency Management Agency (“FEMA”) following Hurricanes Katrina and Rita in 2005. The complaints generally alleged that residents who occupied FEMA supplied emergency housing units, such as travel trailers, were exposed to formaldehyde emitted from the trailers. The plaintiffs alleged various injuries from exposure, including health issues and emotional distress. Most of the initial cases were filed as class action suits. The Judicial Panel on Multidistrict Litigation (the “MDL panel”) had the authority to designate one court to coordinate and consolidate discovery and pretrial proceedings in a proceeding known as multidistrict litigation (“MDL”). The MDL panel transferred the actions to the United States District Court for the Eastern District of Louisiana (the “MDL Court”) because the actions in different jurisdictions involved common questions of fact. The MDL Court denied class certification in December 2008, and consequently, the cases were administered as a mass joinder of claims (the “MDL proceeding”).

On December 21, 2011, the MDL Court issued an Order that, among other matters, mandated certain manufacturing defendants in the litigation, including the Company and several of its RV subsidiaries, to participate in mediation in January 2012. The Company’s Heartland subsidiary participated in a mediation on January 27, 2012 and reached an agreement in principle to resolve the pending claims against it on February 2, 2012. The other Thor RV subsidiaries involved in the MDL proceeding collectively participated in a mediation on January 19, 2012 and during a second mediation session held on February 10, 2012 reached an agreement in principle to resolve the litigation. On March 27, 2012, Heartland and its insurance carriers entered into a Memorandum of Understanding (“MOU”) memorializing the February 2, 2012 settlement. On March 30, 2012, Thor Industries, Inc., for itself and on behalf of its other RV subsidiaries involved in the MDL proceeding, and its insurance carriers, entered into an MOU memorializing the settlement reached on February 10, 2012.

As previously reported on April 19, 2012 by the Company on its Form 8-K, the Company and its RV subsidiaries involved in the MDL proceeding, their respective insurance carriers, several unaffiliated manufacturers of RVs and their insurers, and legal representatives of the plaintiffs each executed a Stipulation of Settlement in April 2012 (the “Stipulation of Settlement”).

On June 1, 2012, the Company paid $4,700 into the Registry of the United States District of Louisiana. This payment represents full payment of the Company and its subsidiaries’ obligation under the Stipulation of Settlement.

On September 27, 2012, after counsel for the plaintiffs produced the list of members of the class who requested exclusion from the proposed settlement, the MDL Court conducted a Fairness Hearing during which final approval of the proposed settlement was evaluated. On that same date, the Court approved the settlement and entered a final, appealable order dismissing all of the claims pending in the MDL litigation. Because no plaintiffs with claims against the Company or any of its subsidiaries opted out of the settlement, this order, assuming no appeal is taken, effectively ends the litigation against the Company and its subsidiaries.

No appeal was taken in relation to the claims against the Company or its subsidiaries. The MDL Court then appointed a Special Master to allocate all pending settlements. On March 29, 2013, the MDL Court approved a methodology pertaining to the allocation of the settlements. On April 2, 2013, the Special Master filed a motion before the MDL Court seeking to establish an allocation and objection procedure. As mentioned above, the Company and all of its subsidiaries involved in this litigation have fully funded the settlements by depositing the agreed upon amounts into the Registry of the United States District of Louisiana.

Executive Overview

We were founded in 1980 and through our operating subsidiaries have grown to be the largest manufacturer of Recreation Vehicles (“RVs”) and a major manufacturer of commercial buses in North America. Our U.S. RV industry market share in the travel trailer and fifth wheel portion of the towable segment is approximately 38% for the calendar quarter ended March 31, 2013. In the motorized segment of the RV industry, we have a U.S. market share of approximately 26% for the calendar quarter ended March 31, 2013. Our U.S. and Canada market share in small and mid-size buses is approximately 34% for the calendar year ended December 31, 2012. We also manufacture and sell 40-foot buses at our facility in Southern California.

Our business model includes decentralized operating units and we compensate operating management primarily with a combination of cash and restricted stock units, based upon the profitability of the business unit which they manage. Our corporate staff provides financial management, insurance, legal, human resource, risk management and internal audit functions. Senior corporate management interacts regularly with operating management to assure that corporate objectives are understood and are monitored appropriately.

Our RV products are sold to dealers who, in turn, retail those products. Our buses are sold through dealers to municipalities and private purchasers such as rental car companies and hotels. We generally do not finance dealers directly, but do provide repurchase agreements to certain of the dealers’ floor plan lenders.

Our growth has been internal and by acquisition. Our strategy has been to increase our profitability in North America in the RV industry and in the bus business through product innovation, service to our customers, manufacturing quality products, improving efficiencies of our facilities and acquisitions. We have not entered unrelated businesses and have no plans to do so in the future.

We rely on internally generated cash flows from operations to finance our growth although we may borrow to make an acquisition if we believe the incremental cash flows will provide for rapid payback. Capital expenditures of $14,711 for the nine months ended April 30, 2013 were made primarily for building and office additions and improvements and to replace machinery and equipment used in the ordinary course of business.

Federal Coach’s product lines are more focused on the luxury bus market which is complementary to our existing product offerings.

During fiscal 2012, the Company purchased a combined total of 3,000,000 shares of the Company’s common stock and held them as treasury stock at a total cost of $77,000. Of the 3,000,000 shares, 2,000,000 were repurchased from the Estate of Wade F.B. Thompson (the “Estate”) in two separate private transactions at a total cost of $48,500. Both of these transactions were evaluated and approved by members of our board of directors who are not affiliated with the Estate. In a third separate private transaction, the Company repurchased 1,000,000 shares from Catterton Partners VI, L.P., Catterton Partners VI Offshore, L.P., CP6 Interest Holdings, L.L.C., and CPVI Coinvest, L.L.C. at a total cost of $28,500. The Company used available cash to purchase all of these shares, which collectively represented 5.4% of the Company’s issued and outstanding common stock prior to the repurchases. Each of these transactions is more fully discussed in Note 12 to the Condensed Consolidated Financial Statements.

Industry Outlook

The Company monitors the industry conditions in the RV market through the use of monthly wholesale shipment data as reported by the Recreation Vehicle Industry Association (“RVIA”) which is typically issued on a one month lag and represents manufacturers’ RV production and delivery to dealers. In addition, we also monitor monthly retail sales trends as reported by Statistical Surveys, Inc. (“Stat Surveys”). Stat Surveys data is typically issued on a month and a half lag. The Company believes that monthly RV retail sales data is important as consumer purchases impact future dealer orders and ultimately our production.

We believe our dealer inventory is at appropriate levels for seasonal consumer demand, with dealers optimistic yet cautious. RV dealer inventory of Thor products as of April 30, 2013 increased 14.4% to 64,899 units from 56,734 units as of April 30, 2012. Thor’s RV backlog as of April 30, 2013 increased 44.9% to $649,584 from $448,403 as of April 30, 2012.

Industry Wholesale Statistics

Key wholesale statistics for the RV industry, as reported by RVIA, are as follows:

(1) Excluding Folding Camping Trailers and Truck Campers, which the Company does not manufacture.

In March 2013, RVIA forecasted that calendar year 2013 shipments for towables and motorized units will be 261,200 and 31,900 units, respectively, approximately 7.5% and 13.1% higher than the corresponding calendar year 2012 wholesale shipments.

Industry Retail Statistics

We believe that retail demand is the key to continued improvement in the RV industry. With appropriate levels of dealer inventory currently, we believe that RV industry wholesale shipments will generally be on a one-to-one replenishment ratio with retail sales going forward. We also believe that current levels of discounting will continue in the near term due to competitive pressures.
