Notes to the Consolidated Financial Statements (Unaudited)

The accompanying unaudited interim consolidated financial statements contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the consolidated financial position as of August 31, 2012, in addition to the consolidated results of operations and consolidated cash flows for the three-month periods ended August 31, 2012 and 2011. Due to the seasonal nature of the Corporation’s business, interim results are not necessarily indicative of results for the entire year.

The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain information and footnote disclosures normally accompanying the annual consolidated financial statements have been omitted. The audited consolidated balance sheet as of May 31, 2012 and the unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Corporation’s latest annual report on Form 10-K.

The following is a summary of the accounting policies that have a significant effect on the Consolidated Financial Statements.

Investments — The Corporation invests in United States Government securities, which are typically held until maturity and are therefore classified as held-to-maturity and carried at amortized cost.

Accounts Receivable — Trade receivables are based on the amounts billed to dealers and communities. The Corporation does not accrue interest on any of its trade receivables, nor does it have an allowance for credit losses due to favorable collections experience. If a loss occurs, the Corporation’s policy is to recognize it in the period when collectability cannot be reasonably assured.

Inventories — Inventories are stated at the lower of cost or market. Cost is determined under the first-in, first-out method. Physical inventory counts are taken at the end of each reporting quarter.

Property, Plant and Equipment — Property, plant and equipment are stated at cost. Depreciation is computed over the estimated useful lives of the assets using the straight-line method for financial statement reporting and accelerated methods for income tax reporting purposes. Estimated useful lives for significant classes of property, plant and equipment, including idle property, are as follows: Building and improvements 10 to 30 years; machinery and equipment 5 to 8 years. Idle property, net of accumulated depreciation consisted of manufacturing facilities in the following locations: Hemet, California; Ocala, Florida; Elkhart, Indiana; Halstead, Kansas; Mocksville, North Carolina and Fair Haven, Vermont.

Long-lived assets are reviewed for impairment whenever events indicate that the carrying amount of an asset may not be recoverable from projected future cash flows.

Property, Plant and Equipment — (Continued)

If the carrying value of a long-lived asset is impaired, an impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value. The Company believes no impairment of long-lived assets exists at August 31, 2012.

Warranty — The Corporation provides the retail purchaser of its homes with a full fifteen-month warranty against defects in design, materials and workmanship. Recreational vehicles are covered by a one-year warranty. The warranties are backed by service departments located at the Corporation’s manufacturing facilities and an extensive field service system. Estimated warranty costs are accrued at the time of sale based upon current sales, historical experience and management’s judgment regarding anticipated rates of warranty claims. The adequacy of the recorded warranty liability is periodically assessed and the amount is adjusted as necessary.

Income Taxes — The Corporation recognizes deferred tax assets based on differences between the carrying values of assets for financial and tax reporting purposes. The realization of the deferred tax assets is dependent upon the generation of sufficient future taxable income. Generally accepted accounting principles require that an entity consider both negative and positive evidence in determining whether a valuation allowance is warranted. In comparing negative and positive evidence, continual losses in recent years is considered significant, negative, objective evidence that deferred tax assets may not be realized in the future, and generally is assigned more weight than subjective positive evidence of the realizability of deferred tax assets.

As a result of its extensive evaluation of both positive and negative evidence, management maintains a full valuation allowance against its deferred tax assets. The Corporation reports a liability, if any, for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The Corporation recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

Management’s Plan — The Corporation’s management is actively pursing strategies to increase sales and decrease costs. These strategies include but are not limited to:

By implementing these strategies, and having a significant position of its working capital in cash and U.S. Treasury Bills, the Corporation continues to remain diligent for any challenges that may occur.

The following is a summary of investments:

The fair value is determined by a secondary market for U.S. Government Securities. At May 31, 2012, the U.S. Treasury Bills matured within four months. At August 31, 2012, the U.S. Treasury Bills matures within three months.

Total inventories consist of the following:

A reconciliation of accrued warranty and related expenses is as follows:

The Corporation’s gross deferred tax assets of approximately $39 million consist of approximately $25 million in federal net operating loss and tax credit carryforwards, $7 million in state net operating loss carryforwards and $7 million resulting from temporary differences between financial and tax reporting. The federal net operating loss and tax credit carryforwards have a life expectancy of twenty years. The state net operating loss carryforwards have a life expectancy, depending on the state where a loss was incurred, between five and twenty years. If the Corporation, after considering future negative and positive evidence regarding the realization of deferred tax assets, determines that a lesser valuation allowance is warranted, it would record a reduction to income tax expense and the valuation allowance in the period of determination.

Notes to the Consolidated Financial Statements (Unaudited) — (Continued)

The Corporation was contingently liable at August 31, 2012 under repurchase agreements with certain financial institutions providing inventory financing for dealers of its products. Under these arrangements, which are customary in the manufactured housing and recreational vehicle industries, the Corporation agrees to repurchase units in the event of default by the dealer at declining prices over the term of the agreement. The period to potentially repurchase units is between 12 to 24 months.

The maximum repurchase liability is the total amount that would be paid upon the default of the Corporation’s independent dealers. The maximum potential repurchase liability, without reduction for the resale value of the repurchased units, was approximately $69 million at August 31, 2012 and approximately $64 million at May 31, 2012.

The risk of loss under these agreements is spread over many dealers and financial institutions. The loss, if any, under these agreements is the difference between the repurchase cost and the resale value of the units. The Corporation estimates the fair value of this commitment considering both the contingent losses and the value of the guarantee. This amount has historically been insignificant. The Corporation believes that any potential loss under the agreements in effect at August 31, 2012 will not be material to its financial position or results of operations. In addition, there were no obligations or net losses from repurchased units for the first quarter of fiscal 2013 and 2012.

The Corporation is a party to various pending legal proceedings in the normal course of business. Management believes that any losses resulting from such proceedings would not have a material adverse effect on the Corporation’s results of operations or financial position.

Overview

The Corporation designs, produces and markets manufactured housing, modular housing and recreational vehicles (travel trailers, fifth wheels and park models) to independent dealers and manufactured housing communities located throughout the United States and Canada. To better serve the needs of its dealers and communities, the Corporation has eleven manufacturing facilities in ten states. Manufactured housing, modular housing and recreational vehicles are sold to dealers and communities either through floor plan financing with various financial institutions or on a cash basis. While the Corporation maintains production of manufactured housing, modular homes and recreational vehicles throughout the year, seasonal fluctuations in sales do occur. Sales and production of manufactured housing and modular housing are affected by winter weather conditions at the Corporation’s northern plants. Recreational vehicle sales are generally higher in the spring and summer months than in the fall and winter months.

Manufactured and modular housing are marketed under a number of trademarks, and are available in a variety of dimensions. Manufactured housing products are built according to standards established by the U.S. Department of Housing and Urban Development. Modular homes are built according to state, provincial or local building codes. Recreational vehicles include travel trailers, fifth wheels and park models. Travel trailers and fifth wheels are marketed under the following trademarks: “Aljo”; “Bobcat”; “Koala”; “Layton”; “Mountain View”; “Nomad”; “Texan”; “Wagoneer”; “Walkabout”; and “Weekender”. Park models are marketed under the following trademarks: “Cabin Series”; “Cedar Cove”; “Kensington”; “Shore Park Homes”; and “Vacation Villa”. The Corporation’s recreational vehicles are intended to provide temporary living accommodations for individuals seeking leisure travel and outdoor recreation.

Manufactured Housing, Modular Housing and Recreational Vehicle Industry Conditions

Sales of manufactured housing, modular housing and recreational vehicles are affected by the strength of the U.S. economy, interest rate and employment levels, consumer confidence and the availability of wholesale and retail financing. The manufactured housing industry has until recently been affected by declining or stagnating unit shipments. This decline or stagnation, caused primarily by adverse economic conditions, tightening retail and wholesale credit markets and a depressed site-built housing market, is resulting in historically low industry shipments. From January to July 2012 however, total industry shipments were approximately 32,000 units, an approximately 19 percent increase from the same period a year ago.

Tight credit markets for retail and wholesale financing have become a significant challenge for the manufactured housing industry. According to the Manufactured Housing Institute, a lack of retail financing options and restrictive credit standards has negatively affected manufactured home buyers. In addition, a significant decline has occurred in wholesale financing, especially as national floor plan lenders have decreased lending to industry dealers.

Manufactured Housing, Modular Housing and Recreational Vehicle Industry Conditions-(Continued)

The domestic modular housing industry has challenges similar to the manufactured housing industry, such as restrictive retail and wholesale financing, and a depressed site-built housing market. From calendar 2005 to 2011, total industry shipments decreased from approximately 43,000 to 12,000 units, a decline of 72 percent. Information related to the Canadian modular housing industry is not available.

Sales of recreational vehicles are influenced by changes in consumer confidence, employment levels, the availability of retail and wholesale financing and gasoline prices. Industry unit sales of travel trailers and fifth wheels have varied in recent years. From calendar 2007 to the first half of 2009 unit sales decreased as a result of recessionary conditions, decreased household wealth, tightening credit markets for retail and wholesale financing, and excess inventory of new recreational vehicles. Unit sales, however, started increasing in the last half of calendar 2009 and continue to date. The Recreational Vehicle Industry Association (RVIA), notes that uncertainty about job and income prospects, stagnating wages, depressed home values and the likelihood of rising taxes will adversely affect recreational vehicle sales.

First Quarter Fiscal 2013 Results

The Corporation experienced the following results during the first quarter of fiscal 2013:

The Corporation’s housing segment experienced increased net sales in first quarter of fiscal 2013 as compared to the first quarter of fiscal 2012, and management cannot determine with certainty if this trend will continue. This uncertainty is based on continuing negative economic conditions previously referenced.

The recreational vehicle segment experienced decreased net sales in the first quarter of fiscal 2013; caused primarily by a decline in sales to Canadian dealers. Regarding the business environment for fiscal 2013, the RVIA forecasts calendar 2012 travel trailer and fifth wheel shipments of approximately 235,000 units; a 10 percent increase from calendar 2011’s total of approximately 213,000 units. The RVIA also forecasts calendar 2013 travel trailer and fifth wheel shipments of approximately 238,000 units; an 1 percent increase from calendar year 2012’s total. Despite this favorable trend, business conditions in fiscal 2013 could be negatively impacted by adverse factors previously referenced by the RVIA.

Net Sales and Unit Shipments — (Continued)

Housing net sales increased approximately 6 percent. The increase was the outcome of the following factors:

Housing unit shipments increased approximately 5 percent. The increase was the outcome of the following factors:

Total domestic manufactured housing unit shipments increased approximately 1 percent. Industry unit shipments for these products increased approximately 10 percent from May to July 2012, the latest three months available as compared to the same period the year prior. Current industry unit shipment data for modular housing is not available. Adverse conditions that caused the Corporation’s unit shipments to lag the industry include:

Compared to prior year, the average net sales price for domestic manufactured housing decreased approximately 3 percent; primarily due to homes sold with less square footage and fewer amenities. The average net sales price for domestic modular and Canadian modular housing products increased approximately 15 percent and 9 percent, respectively. These increases are the result of homes being sold with larger square footage and greater amenities.

Recreational vehicle net sales decreased approximately 10 percent. The decrease was the outcome of the following factors:

Net Sales and Unit Shipments — (Continued)

Recreational vehicle unit shipments decreased approximately 13 percent. The decrease was the outcome of the following factors:

Unit shipments for travel trailers and fifth wheels decreased approximately 13 percent. Industry shipments for these products from May to July 2012, the latest three months available, as compared to the same period the year prior increased approximately 11 percent. The Corporation’s unit shipments lagged the industry due to decreased demand from Canadian dealers. In addition, some competitors maintained larger quantities of finished goods inventory; resulting in an ability to more quickly meet dealer demand. Current industry unit shipment data for park models is not available.

The average net sales price per unit for recreational vehicle products in the first quarter of fiscal year 2013 as compared to the first quarter of fiscal year 2012 increased approximately 3 percent; primarily due to sales price adjustments resulting from higher material costs.

Cost of Sales

Housing cost of sales decreased primarily as a result of decreased manufacturing expenses. As a percentage of sales, cost of sales decreased due to improved margins and lower manufacturing expenses. Recreational vehicle cost of sales decreased due to lower sales.
