UNITED STATES SECURITIES AND EXCHANGE COMMISSION WASHINGTON, D.C. 20549 FORM 8-K CURRENT REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 Date of Report (Date of earliest event reported): September 20, 1999 1-2981 (Commission File Number) --------------------------- FIRSTAR CORPORATION (Exact Name of Registrant as Specified in its Charter) WISCONSIN 39-1940778 (State of Incorporation) (IRS EMPLOYER Identification No.) 777 East Wisconsin Avenue, Milwaukee, Wisconsin 53202 (Address of Registrant's principal executive office) (414) 765-4321 (Registrant's telephone number) FORM 8-K/A FIRSTAR CORPORATION Item 7. Financial Statements, Pro Forma Financial Information and Exhibits (a) Pro Forma Financial Information FIRSTAR CORPORATION AND MERCANTILE BANCORPORATION NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION Note 1-Basis of Presentation 	On September 20, 1999 Firstar Corporation acquired Mercantile Bancorporation Inc. through an exchange of shares. 	The unaudited pro forma condensed combined financial information has been prepared under the pooling of interests method and is based on the historical consolidated financial statements of the two companies adjusted for presentation differences. These restatements were not material. Note 2-Shareholders' Equity 	Under the terms of the merger agreement, Mercantile shareholders received 2.091 shares of Firstar common stock for each share of Mercantile stock owned. Mercantile had 158,672,542 shares of common stock outstanding at September 20, 1999 which was exchanged for approximately 331,748,000 shares of Firstar common stock. The combined company has approximately 981,200,000 shares outstanding after the merger. The common stock in the unaudited pro forma condensed combined balance sheet has been adjusted to reflect the par value amount of shares of the combined company. Pro forma retained earnings reflects an adjustment for estimated merger related charges as described in Note 3 below. Note 3-Merger Related Charges 	In connection with the merger, Firstar and Mercantile expect the combined company to incur pre-tax merger charges of approximately $560 million. These are expected to include losses on the sale of securities of $178 million in conjunction with the balance sheet restructure discussed below, $157 million in employee related payments, $88 million in direct conversion costs, $53 million in charges related to consolidation of systems and operations, $29 million in occupancy and equipment charges (elimination of duplicate facilities and write-off of equipment) and $109 million in other merger related costs (including legal fees, investment banking fees and charitable contributions). Partially offsetting these merger costs will be the reversal of $54 million of prior restructuring and merger accruals of both Firstar and Mercantile. The merger related charges and related tax effect have been reflected in the unaudited pro forma condensed combined balance sheet as of June 30, 1999. The loss on the sale of securities of $178 million is shown on the balance sheet adjustment net of existing market value adjustments of $30 million. The merger charges have not been reflected in the unaudited pro forma condensed combined income statements as they are not expected to have a continuing impact on the operations of the combined company. 	A balance sheet restructuring will occur to conform the combined company's asset and liability management policies. The restructuring, which will include the sale of $6.1 billion of assets, includes the following: the sale of $2.4 billion in U.S. government agency callable securities, $1.9 billion in fixed rate pass-through mortgage-backed securities, $175.0 million non-agency, securities outside Firstar's investment policies and $1.6 billion residential real estate mortgages that will be reclassified as held-for-sale. The proceeds from these sales will be used to reduce short-term borrowings. These transactions have been reflected in the unaudited pro forma condensed combined balance sheet as of June 30, 1999, and have not been reflected in the unaudited pro forma condensed combined statements as they are not expected to have a material impact on the operations of the combined company.
