Exhibit 99(a) UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION On June 7, 1998, Norwest Corporation ("Norwest") entered into a definitive agreement for a merger of equals ("Merger") with Wells Fargo & Company ("Wells Fargo"). In accordance with the agreement, common stockholders of Wells Fargo will receive ten shares of Norwest common stock in exchange for each share of Wells Fargo common stock. The transaction is subject to customary stockholder and regulatory approvals and is expected to close in the fourth quarter of 1998. The pending Merger is significant to the financial statements of Norwest, as specified in Rules 1-02(w) and 3-05 of Regulation S- X. Consequently, pro forma financial statements are presented below.

Basis of Presentation The unaudited pro forma condensed financial information has been prepared using the pooling of interests method of accounting, giving effect to the Merger as if it had occurred as of the beginning of the earliest period presented. The pro forma financial information presented is not necessarily indicative of the results of the operations had the Merger been consummated at the beginning of the periods presented, nor is it necessarily indicative of the results of operations in future periods or the future financial position of the combined entities. Certain historical financial information has been reclassified to conform with the current presentation. The Merger, which is expected to be completed in the fourth quarter of 1998, provides for issuance of ten shares of Norwest common stock for each outstanding share of Wells Fargo common stock, and is subject to regulatory and Norwest stockholder and Wells Fargo stockholder approvals. At June 30, 1998, Norwest had five pending acquisitions (exclusive of the Merger) with total assets of approximately $2.3 billion, and it is expected that approximately 14.0 million common shares will be issued upon consummation of these acquisitions. The pro forma information does not give effect to these other pending acquisitions of Norwest as they are not material to the pro forma condensed financial information, either individually or in the aggregate. Norwest and Wells Fargo anticipate that, in order to comply with Department of Justice merger guidelines, the companies will be requested to sell a modest level of deposits. In this connection, the companies expect to propose divestitures in various markets. The impact of such divestitures is not expected to be material and no adjustment has been included in the unaudited pro forma combined financial statements for the anticipated divestitures. 2. Accounting Policies and Financial Statement Classifications Norwest and Wells Fargo have identified and conformed certain accounting policies, and as described below in Note 4, the accompanying pro forma financial information reflects such conforming accounting adjustments. The accounting policies of both Norwest and Wells Fargo are in the process of being reviewed in detail. Upon completion of such review, other conforming adjustments or financial statement reclassifications may be determined. At June 30, 1998, Wells Fargo goodwill and intangibles amounted to $8.6 billion, and Norwest goodwill and intangibles amounted to $1.1 billion. In conjunction with the Merger and recent financial projections, management is currently in the process of assessing such intangibles for impairment. Transactions between Norwest and Wells Fargo are not material in relation to the pro forma financial information and, therefore, intercompany balances have not been eliminated from the pro forma combined amounts. 3. Non-recurring Merger Charge Pro forma stockholders' equity includes the effect of an estimated non- recurring charge of approximately $950 million, $625 million net of income taxes. Since the estimated charge is non-recurring, it has not been reflected in the pro forma combined condensed statements of income and related per common share calculations. The charge does not include any impairment of intangibles that may be identified upon completion of the review discussed in Note 2. 66 The estimated non-recurring charge consists of the following (in millions): Employee-related expense ...................................... $295 Costs associated with systems integration, operations and customer conversions ......................... 350 Branch consolidations, name change and signage ................ 185 Investment banking, legal and accounting fees ................. 120 950 Income tax benefit ............................................ 325 Total estimated non-recurring charge .......................... $625 The pro forma condensed combined financial information does not reflect any benefit expected from revenue enhancements or derived from potential cost savings related to the Merger. Although management anticipates revenue enhancements and cost savings will result from the Merger, there can be no assurance these items will be achieved. 4. Pro Forma Adjustments The following pro forma adjustments have been reflected in the pro forma condensed combined financial information: - Common stock and surplus were adjusted by $993 million, based on 85.1 million shares of Wells Fargo common stock outstanding at June 30, 1998, reflecting the exchange of 10 shares of Norwest common stock for each share of Wells Fargo common stock, and accounting for the Merger as a pooling of interests. The adjustment reflects the reclassification from surplus to common stock to reflect the $1 2/3 par value of Norwest common stock. The number of shares of Norwest common stock to be issued upon consummation of the Merger will be based on the number of shares of Wells Fargo common stock outstanding at that time and will include approximately 2.5 million "tainted" shares of Wells Fargo common stock that Wells Fargo intends to issue prior to the Merger. From June 1, 1996 to the announcement date of the Merger, Wells Fargo repurchased shares of Wells Fargo common stock that are presumed to be tainted under Accounting Principles Board (APB) Opinion No. 16 and authoritative interpretations thereof. Such shares previously reacquired by Wells Fargo were retired upon acquisition. Wells Fargo rescinded its share repurchase programs as of June 7, 1998. These tainted shares result in violations of certain conditions for the use of pooling of interests accounting for the Merger. Wells Fargo intends to cure such "tainted" shares prior to the effective time of the Merger by issuing shares of Wells Fargo common stock in a manner that complies with the requirements of APB Opinion No. 16 and authoritative interpretations thereof. - Other liabilities and retained earnings were adjusted by $950 million ($625 million, net of income taxes), to reflect the non-recurring Merger charge discussed in Note 3. - Other liabilities and retained earnings have been adjusted by $153 million before taxes ($100 million, net of income taxes) reflecting the transition obligation for the Wells Fargo postretirement medical and life insurance benefits upon initial adoption of Statement of Financial Accounting Standards No. 106, "Employers' Accounting for Postretirement Benefits Other Than Pensions" (FAS 106) at the beginning of 1992. Norwest adopted FAS 106 in 1992 and immediately recognized the accumulated postretirement benefit obligations at the time of adoption as a cumulative effect of change in accounting principle. Subsequent to 67 1992, salaries and benefits expense has been reduced and retained earnings has been credited to eliminate the annual pre-tax charge of $8 million ($5 million, net of income taxes) related to the amortization of the Wells Fargo transition obligations. Premises and equipment and retained earnings have been adjusted by $107 million before taxes ($70 million, net of income taxes) reflecting the conforming of capitalization policies for premises and equipment. The capitalization policy of the pro forma combined company reflects a higher dollar threshold for capitalizing purchases of furniture and equipment that is currently used by one of the parties to the Merger. Use of a higher dollar threshold is consistent with the size of the combined company. Equipment expense has been adjusted by $5 million for the first half of 1998 and 1997, respectively, reflecting adjustments for capitalization of such items, partially offset by related depreciation previously recorded. 5. Pro forma Earnings Per Share The pro forma combined basic and diluted earnings per share for the respective periods presented is based on the combined weighted average number of common and dilutive potential common shares and adjusted weighted shares of Norwest and Wells Fargo. The number of weighted average common shares and adjusted weighted average shares, including all dilutive potential common shares, reflects the exchange of ten shares of Norwest common stock for each share of Wells Fargo common stock. Amounts used in the determination of pro forma basic and diluted earnings per share are as follows: (In millions) For the Six Months Ended June 30, 1998 1997 Net income $1,401 1,220 Less dividends accrued on preferred stock 18 26 Income available to common stockholders $1,383 1,194 Weighted average shares outstanding 1,613.0 1,646.4 Adjustments for dilutive securities: Assumed exercise of stock options and restricted share rights 22.0 21.7 Assumed conversion of preferred stock and convertible subordinated debentures - - Diluted common shares 1,635.0 1,668.1 68
