Notes to 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 November 30, 2013, in addition to the consolidated results of operations and consolidated cash flows for the three-month and six-month periods ended November 30, 2013 and 2012. 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, 2013 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.

Revenue recognition — Substantially all of the Corporation’s products are made to order. Revenue is recognized upon completion of the following: an order for a unit is received from a dealer or community (customer); written or verbal approval for payment is received from a customer’s financial institution or payment is received; a common carrier signs documentation accepting responsibility for the unit as agent for the customer; and the unit is removed from the Corporation’s premises for delivery to a customer. Freight billed to customers is considered sales revenue, and the related freight costs are cost of sales. Volume based rebates paid to dealers are classified as a reduction of sales revenue. Sales of parts are classified as revenue.

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.

Workers’ Compensation Security Deposit — Deferred workers’ compensation deposit represents funds placed with the Corporation’s worker’s compensation insurance carrier to offset future medical claims and benefits.

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

Note Receivable — The Corporation’s note receivable represents the amount owed for the sale of two idle recreational vehicle facilities in Hemet, California; less cash received on the date of closing and cash received from principal repayments through November 30, 2013. Interest is accrued on a monthly basis. No allowance for credit losses exists due to favorable collections experience. The Corporation’s management evaluates the credit quality of the note on a monthly basis. The Corporation’s policy is to recognize a loss in the period when collectability cannot be reasonably assured.

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. At November 30, 2013, Idle property, net of accumulated depreciation consisted of manufacturing facilities in the following locations: Ocala, Florida; Elkhart, Indiana; and Halstead, Kansas. At May, 31, 2013, Idle property, net of accumulated depreciation consisted of manufacturing facilities in the following locations: Ocala, Florida; Elkhart, Indiana; Halstead, Kansas 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. 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 November 30, 2013.

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.

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

Income Taxes (continued) — 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 — Due to recurring losses, the Corporation is actively pursuing 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’s management believes the Corporation will have sufficient liquidity to meet its obligations through the current operating cycle.

During fiscal 2013, the Corporation entered into an agreement to build and sell 60 manufactured homes to Stewart Homes, Inc., one of its dealers. Stewart Homes Inc. also entered into an agreement to sell these homes to Oakridge Family Homes, L.P., a California limited partnership. As a function of Oakridge Family Homes, L.P. purchasing the 60 homes, the Corporation pledged a $600,000 certificate of deposit as security for certain performances. Subsequent to November 30, 2013, the terms of the certificate of deposit proceeds and security agreement were completed; resulting in the maturation of the certificate of deposit and the receipt of the certificate of deposit proceeds.

The fair value is determined by a secondary market for U.S. Government Securities. At November 30 and May 31, 2013, the U.S. Treasury Bills matures within two and three months, respectively.

Total inventories consist of the following:

During the second quarter of fiscal 2013, the Corporation sold two idle recreational vehicle facilities in Hemet, California. The sale of the facilities included a down payment of $500,000 and a promissory note of $1,700,000 to the Corporation. Selling expenses related to the sale, which were paid by the Corporation, were approximately $152,000. This resulted in net cash received from the transaction of approximately $348,000. The note bears an interest rate of 6 percent per annum, requires monthly payments following a 20 year amortization schedule, and provides for a final payment after 6 years. In addition, the two facilities are collateral for the note. The current and non-current balance of $1,654,000 represents the original amount of the note less principal payments received through November 30, 2013.

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

At November 30, 2013, the Corporation’s gross deferred tax assets of approximately $43 million consist of approximately $29 million in federal net operating loss and tax credit carryforwards, $8 million in state net operating loss carryforwards, and $6 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. The Corporation has recorded a full valuation allowance against this asset. 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.

The Corporation was contingently liable at November 30 and May 31, 2013 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.

Skyline Corporation and Subsidiary Companies

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

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 $65 million at November 30, 2013 and approximately $71 million at May 31, 2013. As a result of favorable experience regarding repurchased units, which is largely due to the strength of dealers selling the Corporation’s products, the Corporation maintained at November 30 and May 31, 2013, a $100,000 loss reserve that is a component of other accrued liabilities.

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 November 30, 2013 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 half of each of fiscal 2014 and 2013.

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.

As referenced in Note 2, the Corporation pledged a $600,000 certificate of deposit as security for certain performances in providing 60 manufactured homes to Oakridge Family Homes, L.P. Subsequent to November 30, 2013, the terms of the certificate of deposit proceeds and security agreement were completed; resulting in the maturation of the certificate of deposit and the receipt of the certificate of deposit proceeds.

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 nine 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”; “AlumaSky”; “Ecocamp”; “Koala”; “Layton”; “Nomad”; “Skycat”; “Walkabout”; and “Weekender”. Park models are marketed under the following trademarks: “Cabin Series”; “Cedar Cove”; “Kensington”; “Shore Park Homes”; “Stone Harbor”; 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 had been affected by declining unit shipments to historically low levels. Shipments totaled approximately 373,000 units in 1998; steadily declining to approximately 50,000 units by 2010. This decline was caused primarily by adverse economic conditions, tightening retail and wholesale credit markets and a depressed site-built housing market. Shipments, however, increased to approximately 52,000 and 55,000 units in 2011 and 2012, respectively. From January to November 2013, shipments were approximately 56,000 units; an approximately 9 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 2006 to 2012, total industry shipments decreased from approximately 39,000 to 13,000 units, a decline of 67 percent. From January to September 2013, however, industry shipments were approximately 11,000 units; an approximately 5 percent increase from the same period a year ago. 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 continued growth in recreational vehicle shipments is due to a combination of easing credit terms and availability of loans, increasing household wealth, and continued gains in jobs. These positive factors, however, could be negatively affected by rising interest rates.

Second Quarter Fiscal 2014 Results

The Corporation experienced the following results during the second quarter of fiscal 2014:

The Corporation’s housing segment experienced increased net sales in the second quarter of fiscal 2014 as compared to the second quarter of fiscal 2013, and management cannot determine with certainty if this trend will continue. This uncertainty is based on potential adverse changes in economic growth, interest rate and employment levels, consumer confidence, and the availability of wholesale and retail financing.

Second Quarter Fiscal 2014 Results — (Continued)

The recreational vehicle segment experienced decreased net sales in the second quarter of fiscal 2014. Regarding the business environment for fiscal 2014, the RVIA forecasts calendar 2013 travel trailer and fifth wheel shipments of approximately 264,000 units; an 9 percent increase from calendar 2012’s total of approximately 243,000 units. In addition, the RVIA forecasts 2014 travel trailer and fifth wheel shipments of approximately 279,000 units; a 6 percent increase from 2013’s estimated total. Despite this favorable trend, business conditions in fiscal 2014 could be negatively impacted by adverse factors previously referenced by the RVIA.

Due to recurring losses, the Corporation is actively pursuing 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’s management believes the Corporation will have sufficient liquidity to meet its obligations through the current operating cycle.

Net Sales and Unit Shipments — (Continued)

Housing net sales increased approximately 34 percent. The increase was the outcome of the following factors:

Housing unit shipments increased approximately 39 percent. The increase was the outcome of the following factors:

As previously noted, total domestic manufactured housing unit shipments increased approximately 50 percent. Industry unit shipments for these products increased approximately 19 percent from September to November 2013 as compared to the same period the year prior. The improvement is the result of increased sales to manufactured housing communities.

Total modular housing unit shipments decreased approximately 6 percent. Current industry unit shipment data is not available. Management believes that the decrease in modular housing sales is the result of a temporary softness in demand from modular dealers and developers.

Compared to prior year, the average net sales price for domestic manufactured housing and modular housing products decreased approximately 2 percent, respectively; primarily due to homes sold with less square footage and fewer amenities. The average net sales price for Canadian modular housing products increased approximately 4 percent; primarily due to homes sold with larger square footage and greater amenities.

Recreational vehicles net sales revenue decreased approximately 39 percent. The decrease was the outcome of the following factors:

Net Sales and Unit Shipments — (Continued)

Recreational vehicle unit shipments decreased approximately 45 percent. The decrease was the outcome of the following factors:

Unit shipments for travel trailers and fifth wheels decreased approximately 46 percent. Industry shipments for these products increased approximately 11 percent from September to November 2013 as compared to the same period the year prior. The Corporation’s unit shipments lagged the industry primarily due to two factors. Unit shipments to domestic dealers were adversely affected by some competitors maintaining larger quantities of finished goods inventory; resulting in the ability to meet dealer demand immediately. In addition, the Corporation experienced decreased demand from Canadian dealers. Current industry unit shipment data for park models is not available.

Compared to prior year, the average net sales price per unit for recreational vehicles sold domestically increased approximately 10 percent; primarily due to models sold with larger square footage and greater amenities.

Cost of Sales

Housing cost of sales, in dollars, increased as a result of increased unit shipments. As a percentage of net sales, housing cost of sales decreased due to certain manufacturing expenses remaining fixed amid rising sales.

Recreational vehicle cost of sales declined due to decreased unit shipments. As a percentage of net sales, recreational vehicle cost of sales increased as a result of certain manufacturing expenses remaining fixed amid declining sales.

Selling and Administrative Expenses

Selling and administrative expenses, in dollars and as a percent of net sales, decreased primarily as a result of a decline in dealer and trade show expenses. In addition, a $100,000 decrease occurred in the expense related to the Corporation’s liability for retirement and death benefits offered to certain current and former employees. The decrease occurred as a result of a determination by management that a lower valuation of the liability at November 30, 2013 was warranted.

Gain on Sale of Idle Property and Equipment

In the second quarter of fiscal 2014, the Corporation sold an idle housing facility located in Fair Haven, Vermont. The gain on the sale of this facility was $162,000. In the second quarter of fiscal 2013, the Corporation sold two idle recreational vehicle facilities located in Hemet, California. The gain on the sale of the facilities was $1,411,000.

Loss Before Income Taxes

The operating loss for the housing segment decreased due to the effect of increased net sales, with certain manufacturing expenses remaining fixed as previously referenced.

Recreational vehicle operating loss increased due to the effect of decreased net sales, with certain manufacturing expenses remaining fixed as previously noted.

General corporate expenses decreased primarily due to a $100,000 decrease in the expense related to the Corporation’s liability for retirement and death benefits offered to certain current and former employees as previously referenced.

Interest income for second quarter of fiscal 2014 consisted of interest from the Corporation’s note receivable. Interest income for the second quarter of fiscal 2013 consisted of approximately $5,000 from the Corporation’s note receivable, and approximately $4,000 from investment in U.S. Treasury Bills.
