Forward-looking statements relate to analyses and other information that are based on forecasts of future results and estimates of amounts not yet determinable. These statements also relate to our future prospects, developments and business strategies. These statements are subject to uncertainties and factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control, that could cause actual results to differ materially from those expressed in or implied by these forward-looking statements.

These forward-looking statements are identified by use of terms and phrases such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “will,” and similar terms and phrases, including references to assumptions. These statements are contained in the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other sections of this Form 10-Q.

The following factors are among those that may cause actual results to differ materially from the forward-looking statements:

The unaudited consolidated financial statements included herein have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles, also known as GAAP, for complete financial statements.

In the opinion of management, all adjustments (including normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the six months ended June 30, 2004 are not necessarily indicative of the results that may be expected for the year ending December 31, 2004.

Note 10 — Stock Options

In May 2001, we adopted the 2001 Westcorp Stock Option Plan, also known as the 2001 Plan, an incentive stock option plan for certain associates and directors. The 2001 Plan replaced the 1991 Stock Option Plan, also known as the 1991 Plan that expired on April 15, 2001. Those who received options prior to the approval of the 2001 Plan are still subject to the 1991 Plan and may continue to exercise the remaining shares that are outstanding and exercisable. However, any and all shares reserved for the 1991 Plan are no longer available for future grants. As such, no further grants will be made under the expired 1991 Plan.

Options outstanding and exercisable at June 30, 2004 were as follows:

Stock option activity is summarized as follows:

Option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Our stock options have characteristics significantly different from traded options, and changes in the subjective input assumptions can materially affect the fair value estimate. Although we do not believe that there is a reliable single measure of the fair value of our employee stock options, we use the Binomial option valuation model to determine such value. We believe that this model provides a more reliable measure than the Black-Scholes model. The weighted average fair value of options granted during the period ending June 30, 2004 was $13.26 compared to $5.48 for the year ended December 31, 2003.

Pro forma information regarding net income and earnings per share is required by Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation, as amended by Statement of Financial Accounting Standards No. 148, Accounting for Stock-Based Compensation – Transition and Disclosure – an amendment of FASB Statement No. 123, and has been determined as if we had accounted for our employee stock options under the fair value method of that statement.

Pro forma net income and diluted earnings per share for the respective periods were as follows:

Note 11 – Commitments and Contingencies

We or our subsidiaries are involved as parties to certain legal proceedings incidental to our business, including Lee, et al. v. WFS Financial Inc, United States District Court, Middle District of Tennessee at Nashville, No. 3-02-0570 filed June 17, 2002 (a putative class action raising claims under the Equal Credit Opportunity Act) and other similar cases. Beginning on May 24, 2004 and continuing thereafter, a total of four separate purported class action lawsuits relating to the announcement by Westcorp and WFS that Westcorp was commencing an exchange offer for the outstanding public shares of WFS were filed in the Orange County, California Superior Court against Westcorp, WFS, and individual board members of Westcorp and WFS. On June 24, 2004, the actions were consolidated under the caption In re WFS Financial Shareholder Litigation, Case No. 04CC00559. On July 16, 2004, the court granted a motion by plaintiff Alaska Hotel & Restaurant Employees Pension Trust Fund, in Case No.04CC00573, to amend the consolidation order to designate it the lead plaintiff in the litigation, and gave plaintiff until July 30, 2004 to file an amended consolidated complaint in the action. All of the shareholder-related actions allege, among other things, that the defendants breached their respective fiduciary duties and seek to enjoin or rescind the transaction and obtain an unspecified sum in damages and costs, including attorneys’ fees and expenses. We are vigorously defending these actions and do not believe that the outcome of these proceedings will have a material effect upon our financial condition, results of operations and cash flows.

Note 12 – Proposed Acquisition and Merger

On May 23, 2004, we entered into a definitive agreement pursuant to which we will acquire the outstanding 16% common stock minority interest of WFS not already owned by our wholly owned subsidiary, the Bank. The acquisition is structured as a merger of WFS with and into the Bank. The public holders of WFS shares will receive 1.11 shares of our common stock for each share of WFS common stock held by them in a tax-free exchange. Based on the $42.60 closing price of our common stock on May 21, 2004, the last business day prior to the execution of the agreement, the transaction has an indicated value of $47.29 per share of WFS common stock. In connection with the merger, the Bank has filed an application with the California Department of Financial Institutions to convert its federal thrift charter to a California state bank charter. The merger agreement is conditioned upon the conversion of the charter. The transaction is subject to, among other closing conditions, the receipt of regulatory approvals and the approval of a majority of WFS Financial’s shareholders, other than shares controlled by Westcorp.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

We are a diversified financial services holding company that provides automobile lending services through our second tier subsidiary, WFS Financial Inc, also known as WFS, and retail and commercial banking services through our wholly owned subsidiary, Western Financial Bank, also known as the Bank. The Bank currently owns 84% of the capital stock of WFS.

Our primary sources of revenue are net interest income and noninterest income. Net interest income is the difference between the income earned on interest earning assets and the interest paid on interest bearing liabilities. We generate interest income from our loan portfolio, which consists of consumer, mortgage and commercial loans, and from investments in mortgage-backed securities and other short-term investments. We fund our loan portfolio and investments with deposits, advances from the Federal Home Loan Bank, also known as the FHLB, securities sold under agreements to repurchase, securitizations, other borrowings and equity.

Noninterest income is primarily made up of revenues generated from the servicing of automobile contracts and real estate loans. The primary components of noninterest income include late charges and other miscellaneous servicing fee income. Other components of noninterest income include gains and losses from the sale of investment securities and mortgage-backed securities, insurance income, fees related to the sales of investment products such as mutual funds and annuities, and fee income from depository accounts. The primary components of noninterest expense are salaries, credit and collection expenses, and data processing costs.

Since this table is only a summary and does not provide all of the information contained in our financial statements, including the related notes, you should read our Consolidated Financial Statements contained elsewhere herein.
