NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — Summary of Significant Accounting Policies

Operations

William Lyon Homes, a Delaware corporation and subsidiaries (the “Company”) are primarily engaged in designing, constructing and selling single family detached and attached homes in California, Arizona and Nevada.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and all majority-owned subsidiaries and joint ventures. Investments in joint ventures in which the Company has a 50% or less ownership interest are accounted for using the equity method. The accounting policies of the joint ventures are substantially the same as those of the Company. All significant intercompany accounts and transactions are eliminated in consolidation.

Segment Information

The Company designs, constructs and sells a wide range of homes designed to meet the specific needs of each of its markets. For internal reporting purposes, the Company is organized into five geographic home building regions and its mortgage origination operation. Because each of the Company’s geographic home building regions has similar economic characteristics, housing products and class of prospective buyers, the geographic home building regions have been aggregated into a single home building segment. The Company’s mortgage origination operations did not meet the materiality thresholds which would require disclosure for the years ended December 31, 2002, 2001 and 2000, and accordingly, are not separately reported.

The Company evaluates performance and allocates resources primarily based on the operating income of individual home building projects. Operating income is defined by the Company as operating revenue less operating costs plus equity in income of unconsolidated joint ventures. Accordingly, operating income excludes certain expenses included in the determination of net income. Operating income from home building operations totaled $65.1 million, $46.2 million and $49.4 million for the years ended December 31, 2002, 2001 and 2000, respectively.

All revenues are from external customers. There were no customers that contributed 10% or more of the Company’s total revenues during 2002, 2001 or 2000.

Real Estate Inventories and Related Indebtedness

Real estate inventories are carried at cost net of impairment losses, if any. Real estate inventories consist primarily of deposits, raw land, lots under development, homes under construction and completed homes of real estate projects. All direct and indirect land costs, offsite and onsite improvements and applicable interest and other carrying charges are capitalized to real estate projects during periods when the project is under development. Land, offsite costs and all other common costs are allocated to land parcels benefited based upon relative fair values before construction. Onsite construction costs and related carrying charges (principally interest and property taxes) are allocated to the individual homes within a phase based upon the relative sales value of the homes. The Company relieves its accumulated real estate inventories through cost of sales for the cost of homes sold. Selling expenses and other marketing costs are expensed in the period incurred. A provision for warranty costs relating to the Company’s limited warranty plans is included in cost of sales at the time the sale of a home is recorded. The Company generally reserves one percent of the sales price of its homes against

the possibility of future charges relating to its one-year limited warranty and similar potential claims. Factors that affect the Company’s warranty liability include the number of homes under warranty, historical and anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the amounts as necessary. Changes in the Company’s warranty liability during the year ended December 31 are as follows (in thousands):

Interest incurred under the Revolving Credit Facilities, the 12  ¹ / 2 % Senior Notes and other notes payable, as more fully discussed in Note 5, is capitalized to qualifying real estate projects under development. Any additional interest charges related to real estate projects not under development are expensed in the period incurred.

In August 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (“Statement No. 144”). This pronouncement superseded Statement of Financial Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of (“Statement No. 121”) and was required to be adopted on January 1, 2002. Statement No. 144 retained the fundamental provisions of Statement No. 121 as it relates to assets to be held and used and assets to be sold. Statement No. 144 requires impairment losses to be recorded on assets to be held and used by the Company when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of the assets. When an impairment loss is required for assets to be held and used by the Company, the related assets are adjusted to their estimated fair value.

Fair value represents the amount at which an asset could be bought or sold in a current transaction between willing parties, that is, other than a forced or liquidation sale. The estimation process involved in determining if assets have been impaired and in the determination of fair value is inherently uncertain because it requires estimates of current market yields as well as future events and conditions. Such future events and conditions include economic and market conditions, as well as the availability of suitable financing to fund development and construction activities. The realization of the Company’s real estate projects is dependent upon future uncertain events and conditions and, accordingly, the actual timing and amounts realized by the Company may be materially different from their estimated fair values.

Property and Equipment

Property and equipment are stated at cost and depreciated using the straight-line method over their estimated useful lives ranging from three to thirty-five years. Leasehold improvements are stated at cost and are amortized using the straight-line method over the shorter of either their estimated useful lives or term of the lease.

Deferred Loan Costs

Deferred loan costs are amortized over the term of the applicable loans using a method which approximates the level yield interest method.

Goodwill

The amount paid for business acquisitions over the net fair value of assets acquired and liabilities assumed is reflected as goodwill and, until January 1, 2002 was being amortized on a straight-line basis over seven years. Accumulated amortization was $2,793,000 as of December 31, 2001. In June 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets (“Statement No. 142”), effective for fiscal years beginning after December 15, 2001. Under the new rule, goodwill is no longer amortized but is subject to impairment tests in accordance with Statement No. 142. The Company performed its first required annual impairment test of goodwill as of January 1, 2002 and determined that goodwill was not impaired. As of December 31, 2002, there have been no indicators of impairment related to the Company’s goodwill. If Statement No. 142 had been adopted effective January 1, 2000, the pro forma impact of the nonamortization of goodwill on the results for the subsequent periods would have been as follows (in thousands except per common share data):

Sales and Profit Recognition

A sale is recorded and profit recognized when a sale is consummated, the buyer’s initial and continuing investments are adequate, any receivables are not subject to future subordination, and the usual risks and rewards of ownership have been transferred to the buyer in accordance with the provisions of Financial Accounting Standards Board Statement of Financial Accounting Standards No. 66, Accounting for Sales of Real Estate (“Statement No. 66”). When it is determined that the earnings process is not complete, profit is deferred for recognition in future periods. The Company accounts for sale-leaseback transactions in accordance with the provisions of Financial Accounting Standards Board Statement of Financial Accounting Standards No. 98, Accounting for Leases (“Statement No. 98”).

During the year ended December 31, 2001, the Company completed the sale and related leaseback of 56 model homes for a sales price of $16,216,000, of which $13,938,000 was paid in cash and $2,278,000 of which was paid in the form of a partial recourse note receivable. The sale was accounted for on the cost recovery method in accordance with Statement No. 66 and Statement No. 98, and as such deferred profits of $2,385,000 were recorded resulting in gross profits from the sale of $531,000. As of December 31, 2002, the partial recourse note receivable of $1,379,000 and related deferred profits of $1,486,000 are reflected in receivables and accrued expenses, respectively. The Company pays rent on the related lease and earns income on the partial recourse note receivable at LIBOR plus 4.750% (6.13% at December 31, 2002).

Income Taxes

Income taxes are accounted for under the provisions of Financial Accounting Standards Board Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes. Effective as of January 1, 1994, the

62

Table of Contents

WILLIAM LYON HOMES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Company completed a capital restructuring and quasi-reorganization. The quasi-reorganization resulted in the adjustment of assets and liabilities to estimated fair values and the elimination of an accumulated deficit effective January 1, 1994. Income tax benefits resulting from the utilization of net operating loss and other carryforwards existing at January 1, 1994 and temporary differences existing prior to or resulting from the quasi-reorganization, are excluded from the results of operations and credited to paid-in capital. During the year ended December 31, 2000, income tax benefits of $9,287,000 were excluded from results of operations and not reflected as a reduction to the Company’s provision for income taxes but credited directly to paid-in capital.

Financial Instruments

Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash investments, receivables, and deposits. The Company typically places its cash investments in investment grade short-term instruments. Deposits, included in other assets, are due from municipalities or utility companies and are generally collected from such entities through fees assessed to other developers.

For those instruments, as defined under Financial Accounting Standards Board Statement of Financial Accounting Standards No. 107, Disclosures About Fair Value of Financial Instruments, for which it is practical to estimate fair value, management has determined that the carrying amounts of the Company’s financial instruments approximate their fair value at December 31, 2002.

The Company is an issuer of, or subject to, financial instruments with off-balance sheet risk in the normal course of business which exposes it to credit risks. These financial instruments include letters of credit and obligations in connection with assessment district bonds. These off-balance sheet financial instruments are described in the applicable Notes.

Cash and Cash Equivalents

Short-term investments with a maturity of three months or less when purchased are considered cash equivalents.

Management Fees

Management fees represent fees earned in the current period from unconsolidated joint ventures in accordance with joint venture and/or operating agreements.

Basic and Diluted Earnings Per Common Share

Earnings per share amounts for all periods presented conform to Financial Accounting Standards Board Statement of Financial Accounting Standards No. 128, Earnings Per Share. Basic and diluted earnings per common share for the year ended December 31, 2002 are based on 10,203,497 and 10,474,868 shares of common stock outstanding, respectively. Basic and diluted earnings per common share for the year ended December 31, 2001 are based on 10,583,564 and 10,739,540 shares of common stock outstanding, respectively. Basic and diluted earnings per common share for the year ended December 31, 2000 are based on 10,499,917 and 10,503,572 shares of common stock outstanding, respectively.

Stock-Based Compensation

At December 31, 2002, the Company had stock plans, which are described more fully in Note 6. The Company accounts for those plans under the recognition and measurement principles of APB Opinion No. 25, Accounting for Stock Issued to Employees (“APB No. 25”) and related interpretations. No stock-based employee compensation cost is reflected in net income, as all options granted under those plans had an exercise price equal

to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income and earnings per common share if the Company had applied the fair value recognition provisions of Financial Accounting Standards Board Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (“Statement No. 123”) to stock-based employee plans (in thousands, except per common share amounts):

Use of Estimates

The preparation of the Company’s 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 the assets and liabilities as of December 31, 2002 and 2001 and revenues and expenses for each of the three years in the period ended December 31, 2002. Accordingly, actual results could differ from those estimates in the near-term.

Impact of New Accounting Pronouncements

In April 2002, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 145, Recission of SFAS Nos. 4, 44 and 64, Amendment of FASB Statement No. 13 and Technical Corrections (“Statement No. 145”). Statement No. 145 prevents gains or losses on extinguishment of debt not meeting the criteria of APB 30 to be treated as extraordinary. Statement No. 145 is effective for fiscal years beginning after March 15, 2002. Upon adoption of Statement No. 145, the Company’s previously reported extraordinary items related to gain from retirement of debt will be reclassified and not reported as extraordinary items.

In December 2002, the Financial Accounting Standards Board issued Statement of Financial Account Standards No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure (“Statement No. 148”). Statement No. 148 amends Statement No. 123 to provide three alternative methods of transition for Statement No. 123’s fair value method of accounting for stock-based employee compensation for companies that elect to adopt the provisions of Statement No. 123. Transition to the fair value accounting method of Statement No. 123 is not required by Statement No. 148. The Company has elected to use the intrinsic value method of accounting for stock compensation in accordance with APB No. 25 and related interpretations. Statement No. 148 also amends the disclosure provisions of Statement No. 123 to require disclosure in the summary of significant accounting policies of the effects of an entity’s accounting policy with respect to stock-based

64

compensation on reported net income and earnings per share in annual and interim financial statements. The disclosure provisions of Statement No. 148 are required to be adopted by all companies with stock-based employee compensation, regardless of whether they account for that compensation using the fair value method of Statement No. 123 or the intrinsic value method of APB No. 25. The disclosure provisions of Statement No. 148 have been adopted by the Company with appropriate disclosure included in Note 1 above.

In November 2002, the Financial Accounting Standards Board issued Interpretation No. 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others (“Interpretation No. 45”). The disclosure requirements of Interpretation No. 45 are effective as of December 31, 2002. The initial recognition and measurement requirements of Interpretation No. 45 are effective on a prospective basis to guarantees issued or modified after December 31, 2002. The Company is currently evaluating the impact of the required accounting treatment under Interpretation No. 45 for guarantees issued or modified after December 31, 2002. The Company has not determined the anticipated impact of the application of Interpretation No. 45 to guarantees issued or modified after December 31, 2002. However, in the case of a guarantee issued as part of a transaction with multiple elements with an unrelated party, it generally requires the recording at inception of the guarantee of a liability equal to the guarantee’s estimated fair value. In the absence of observable transactions for identical or similar guarantees, estimated fair value will likely be based on the expected present value which is the sum of the estimated probability-weighted range of contingent payments under the guarantee arrangement. The recording of a liability could have a corresponding effect on various of the Company’s financial ratios and other financial and operational indicators. See Notes 4, 5 and 10 for additional information related to the Company’s guarantees.

In January 2003, the Financial Accounting Standards Board issued Interpretation No. 46, Consolidation of Variable Interest Entities (“Interpretation No. 46”), which applies immediately to arrangements created after January 31, 2003. Interpretation No. 46 applies to arrangements created before February 1, 2003 beginning on July 1, 2003. The Company is currently evaluating whether the application of Interpretation No. 46 would require the consolidation of any of the Company’s joint venture or land banking arrangements existing at December 31, 2002. The consolidation of the assets, liabilities and operations of any of the Company’s joint venture or land banking arrangements would have a corresponding effect on various of the Company’s financial ratios and other financial and operational indicators of the Company. Interpretation No 46 may be applied by restating previously issued financial statements with a cumulative-effect adjustment as of the beginning of the first year restated. See Notes 4 and 10 for additional information regarding the Company’s joint venture and land banking arrangements.

Reclassifications

Certain balances in the December 31, 2001 consolidated balance sheet have been reclassified in order to conform to current year presentation.

Note 4—Investments in and Advances to Unconsolidated Joint Ventures

The Company and certain of its subsidiaries are general partners or members in 16 active joint ventures involved in the development and sale of residential projects. Such joint ventures are 50% or less owned by the Company and not controlled by the Company and, accordingly, the financial statements of such joint ventures are not consolidated with the Company’s financial statements. The Company’s investments in unconsolidated joint ventures are accounted for using the equity method. Condensed combined financial information of these joint ventures as of December 31, 2002 and 2001 is summarized as follows:

67

Table of Contents

Income allocations and cash distributions to the Company are based on predetermined formulas between the Company and the joint venture partners as specified in the applicable partnership or operating agreements. The Company generally receives, after partners’ priority returns and return of partners’ capital, approximately 50% of the profits and cash flows from joint ventures.

Certain joint ventures have obtained financing from construction lenders which amounted to $90,086,000 at December 31, 2002. As common practice required by commercial lenders, all of the joint ventures that have obtained financing are obligated to repay loans to a level such that they do not exceed certain required loan-to-value or loan-to-cost ratios. Each lender has the right to test the ratios by appraising the property securing the loan at the time. Either a decrease in the value of the property securing the loan or an increase in the construction costs could trigger this pay down obligation. The term of the obligation corresponds with the term of the loan and is limited to the outstanding loan balance. All of the joint ventures that have obtained such financing are in the form of limited partnerships of which the Company is the general partner. While historically all liabilities of these partnerships have been satisfied out of the assets of such partnerships and while the Company believes that this will continue in the future, the Company, as general partner, is potentially responsible for all liabilities and indebtedness of these partnerships. In addition, the Company has provided unsecured environmental indemnities to some of the lenders who provide loans to the partnerships. The Company has also provided completion guarantees and repayment guarantees for some of the limited partnerships under their credit facilities. The repayment guarantees total $22,312,000 as of December 31, 2002 and only become effective upon repayment of the outstanding 12  ¹ / 2 % Senior Notes.

During the year ended December 31, 2002, one of the joint ventures in which the Company is a general partner completed a land sale to the Company for $17,079,000 resulting in a profit of approximately $3,537,000, all of which was allocated to the Company’s outside partner as preferred return in accordance with the joint venture agreement.

WILLIAM LYON HOMES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

During the year ended December 31, 2002, one of the Company’s existing unconsolidated joint ventures (“Existing Venture”) was restructured such that the Company is required to purchase the 538 lots owned by the Existing Venture on a specified takedown basis through October 15, 2003 at a purchase price equal to the future cost of such lots including a 20% preferred return on invested capital to the outside partner of the Existing Venture (estimated to be $178,578,000, including an estimated preferred return of $36,911,000). During the year ended December 31, 2002, the first 242 lots were purchased from the Existing Venture for $64,468,000, which includes a $12,493,000 preferred return to the outside partner of the Existing Venture. The 242 lots were purchased by a newly formed joint venture (“New Venture”) between the Company and an outside partner. The Company is required to purchase the 242 lots owned by the New Venture on a specified takedown basis through May 15, 2004 at a purchase price equal to $74,210,000 plus a 13  ¹ / 2 % preferred return on invested capital to the outside partner of the New Venture. Because the Company is required to purchase the lots owned by both the Existing Venture and the New Venture, and the Company now controls both ventures, the financial statements of both ventures have been consolidated with the Company’s financial statements as of December 31, 2002, including real estate inventories of $101,849,000 and minority interest in consolidated joint ventures of $80,647,000. During the year ended December 31, 2002, an additional 44 lots were purchased from the Existing Venture for $19,765,000, which includes a $3,953,000 preferred return to the outside partner of the Existing Venture. The 44 lots were purchased though a land banking arrangement (see Note 10 for additional information regarding the Company’s land banking arrangements). The intercompany sale and related profit from the 242 lots and the 44 lots have been eliminated in consolidation.

Interest relating to the above debt consists of the following (in thousands):

Senior Notes

As of December 31, 2002, the Company’s outstanding balance under its 12  ¹ / 2 % Senior Notes was $70,279,000. On May 1, 2001, the Company completed a consent solicitation with respect to the 12  ¹ / 2 % Senior Notes and received consents from holders of $39,279,000 of the then outstanding notes to extend the maturity date from July 1, 2001 to July 1, 2003 and to make certain amendments to the note covenants. Although the Company initially intended to accept consents from no more than 50% of holders, the Company elected to accept additional consents, as contemplated by the consent solicitation documents. The consenting holders received a fee of 4% of the principal balance. Subsequently, during May and June 2001, the Company had also repurchased $31,444,000 of the Senior Notes from non-consenting holders.

In June 2001, General William Lyon, Chairman and Chief Executive Officer of the Company, and a trust for which his son William Harwell Lyon is a beneficiary, purchased from the Company at par $30,000,000 of the 12  ¹ / 2 % Senior Notes. William H. McFarland, another member of the Company’s Board of Directors, purchased from the Company at par $1.0 million of the 12  ¹ / 2 % Senior Notes. In parity with holders consenting during the consent solicitation, these Directors received a consent fee of 4% of the principal balance and consented to the amendments effected by the Company’s consent solicitation statement dated February 28, 2001.

In July 2001, the Company repaid all of the remaining 12  ¹ / 2 % Senior Notes which matured on July 1, 2001 amounting to $5,893,000.

In April, May and November 2000, the Company purchased $22,799,000 principal amount of its outstanding 12  ¹ / 2 % Senior Notes at a cost of $22,107,000. The net gain resulting from the purchase was $496,000 after giving effect to income taxes of $26,000 and amortization of related loan costs of $128,000. Such gain is reflected as an extraordinary item in the Company’s results of operations for the year ended December 31, 2000.

The 12  ¹ / 2 % Senior Notes due July 1, 2001 are obligations of William Lyon Homes, a Delaware corporation (“Delaware Lyon”), and are unconditionally guaranteed on a senior basis by William Lyon Homes, Inc., a California corporation and a wholly-owned subsidiary of Delaware Lyon. However, William Lyon Homes, Inc. has granted liens on substantially all of its assets as security for its obligations under the Revolving Credit Facilities and other loans. Because the William Lyon Homes, Inc. guarantee is not secured, holders of the 12  ¹ / 2 % Senior Notes are effectively junior to borrowings under the Revolving Credit Facilities with respect to such assets. Delaware Lyon and its consolidated subsidiaries are referred to collectively herein as the “Company.” Interest on the 12  ¹ / 2 % Senior Notes is payable on January 1 and July 1 of each year.

The 12  ¹ / 2 % Senior Notes are senior obligations of Delaware Lyon and rank pari passu in right of payment to all existing and future unsecured indebtedness of Delaware Lyon, and senior in right of payment to all future indebtedness of the Company which by its terms is subordinated to the 12  ¹ / 2 % Senior Notes.

Upon certain changes of control as described in the Indenture, Delaware Lyon must offer to repurchase 12  ¹ / 2 % Senior Notes at a price equal to 101% of the principal amount plus accrued and unpaid interest, if any, to the date of repurchase.

The Indenture governing the 12  ¹ / 2 % Senior Notes restricts Delaware Lyon and certain of its subsidiaries with respect to, among other things: (i) the payment of dividends on and redemptions of capital stock, (ii) the incurrence of indebtedness or the issuance of preferred stock, (iii) the creation of certain liens, (iv) consolidations or mergers with or transfer of all or substantially all of its assets and (v) transactions with affiliates. These restrictions are subject to a number of important qualifications and exceptions.

As of December 31, 2002, the outstanding 12  ¹ / 2 % Senior Notes with a face value of $70,279,000 have a fair value of approximately the face value, in the opinion of the Company’s management.
