PROXY STATEMENT

Solicitation of Proxies

This Proxy Statement is being mailed on or about February 28, 2003, to the holders of record as of February 14, 2003, of Common Stock (“Common Stock”) of Fiserv, Inc. (the “Company”) in connection with the solicitation by the Board of Directors of proxies for the Annual Meeting of Shareholders (the “Annual Meeting”). The Annual Meeting will be held at the Company’s corporate offices, 255 Fiserv Drive, Brookfield, Wisconsin 53045, at 10:00 a.m. Central time on April 3, 2003, and at any and all adjournments or postponements thereof. Any shareholder appointing a proxy has the power to revoke it at any time before it is exercised by (i) filing with the Secretary written notice thereof (Charles W. Sprague, Executive Vice President, General Counsel, Secretary and Chief Administrative Officer, Fiserv, Inc., 255 Fiserv Drive, Brookfield, Wisconsin 53045); (ii) appointing a new proxy; or (iii) appearing at the Annual Meeting and giving the Secretary notice of his or her intention to vote in person.

The cost of solicitation of proxies by mail on behalf of the Board of Directors will be borne by the Company. Proxies also may be solicited by personal interview, telephone or electronic communication, in addition to the use of the mail, by Directors, officers and regular employees of the Company, without additional compensation therefor. The Company also has made arrangements with brokerage firms, banks, nominees and other fiduciaries to forward proxy solicitation materials for shares of Common Stock held of record to the beneficial owners of such shares. The Company will reimburse such holders for their reasonable out-of-pocket expenses.

Proxies solicited hereby will be returned to the Board of Directors, and will be tabulated by inspectors of election designated by the Board of Directors, who will not be employees or Directors of the Company, or any of its affiliates.

Purposes of Annual Meeting

The Annual Meeting has been called for the purposes of: (i) electing three Directors to serve for a three-year term expiring in 2006; (ii) approving an amendment to the Company’s Restated Articles of Incorporation to increase the number of authorized shares of Common Stock from 300,000,000 to 450,000,000; and (iii) transacting such other business as may properly come before the Annual Meeting or any adjournments or postponements thereof.

The persons named as proxies in the enclosed proxy card have been selected by the Board of Directors and will vote shares represented by valid proxies. They have indicated that, unless otherwise specified in the proxy card, they intend to vote (i) to elect as Directors the nominees noted herein; and (ii) to approve the amendment to the Company’s Restated Articles of Incorporation to increase the number of authorized shares of Common Stock from 300,000,000 to 450,000,000. The Board of Directors has no reason to believe that any of the nominees will be unable to serve as a Director. In the event, however, of the death or unavailability of any nominee or nominees, the proxy to vote in favor of the election of such nominee or nominees will be voted for such other person as the Board of Directors may recommend.

The Company has no knowledge of any other matters to be presented at the Annual Meeting. In the event other matters are properly brought before the Annual Meeting or any adjournments or

1

postponements thereof, the persons named in the proxy card will vote in accordance with their best judgment on such matters.

Voting Securities

The Board of Directors has fixed the close of business on February 14, 2003, as the record date (the “Voting Record Date”) for determining shareholders entitled to notice of and to vote at the Annual Meeting. On the Voting Record Date, there were 192,013,722 shares of Common Stock outstanding and entitled to vote, and the Company had no other class of securities outstanding. All of these shares are to be voted as a single class, and each holder is entitled to one vote for each share held of record on all matters submitted to a vote of shareholders. The presence, in person or by proxy, of at least a majority of the outstanding shares of Common Stock entitled to vote at the Annual Meeting shall constitute a quorum for the transaction of business. A quorum being present, the approval of the amendment to the Company’s Restated Articles of Incorporation to increase the number of authorized shares from 300,000,000 to 450,000,000 and all other matters, other than the election of Directors, shall require the affirmative vote of a majority of the total votes cast in person or by proxy in order to be approved. Directors will be elected by a plurality of votes cast at the Annual Meeting. Abstentions will be included in the determination of shares present and voting for purposes of determining whether a quorum exists. Broker non-votes will not be so included. Neither abstentions nor broker non-votes will be counted in determining whether a proposal has been approved. In the event there are not sufficient votes for a quorum or to approve any proposal at the time of the Annual Meeting, the Annual Meeting may be adjourned or postponed in order to permit the further solicitation of proxies.

An individual who has a beneficial interest in shares allocated to his or her account under the 401(k) Savings Plan of Fiserv, Inc. and Its Participating Subsidiaries or the Fiserv Predecessor Employer Retirement Plan (collectively, the “Plans”) is being sent this Proxy Statement and a proxy card to provide instructions to vote the shares of Common Stock allocated to his or her account. A participant may use the proxy card to give directions to the Trustees of the Plans as to how his or her allocated shares should be voted by completing, signing, dating and returning the proxy card. If the participant does not sign and return this card, or if the participant does not attend the meeting and vote by ballot, the Trustees of the Plans will vote the shares in the same manner and in the same proportion as the shares for which voting instructions are received from other participants, except that the Trustees, in the exercise of their fiduciary duties, may determine that they must vote the shares in some other manner.

Matter 2. Amendment to the Restated Articles of Incorporation to Increase Authorized Shares of Common Stock.

The Company currently has 325,000,000 shares of capital stock authorized consisting of 300,000,000 shares of Common Stock and 25,000,000 shares of Preferred Stock. As of the Voting Record Date, 192,013,722 shares of Common Stock were issued and outstanding, and 10,012,089 shares of Common Stock were reserved for issuance under the Company’s employee stock purchase and stock option plans. Accordingly, there now are only 97,974,189 authorized shares of Common Stock that are not reserved and that may be issued for any future business purposes by the Company, including stock dividends.

The Board of Directors has approved for submission to shareholders, and recommends that the shareholders approve, an amendment to the Company’s Restated Articles of Incorporation to increase the number of shares of Common Stock that the Company is authorized to issue from 300,000,000 to 450,000,000.

The purpose of increasing the number of authorized shares of Common Stock is to have additional shares available for general corporate purposes, including stock dividends, stock splits, issuing stock in acquisitions, issuing stock in connection with employee incentive and retirement plans, raising additional equity capital and other uses. The Company has no current plans to issue any shares of Common Stock from this proposed increase. However, by approving this increase now in advance of any specific need, the Company believes that it will have the flexibility to act in a timely manner when and as the need to issue additional shares in the future does arise, without the delay and expense that would be required at that time to obtain shareholder approval of such an increase at a special meeting.

6

The Board of Directors has not proposed the increase in the amount of authorized Common Stock with the intention of discouraging tender offers or takeover attempts of the Company. However, the availability of additional authorized shares for issuance could render more difficult or discourage a merger, tender offer, proxy contest or other attempt to obtain control of the Company, which may adversely affect the ability of the Company’s shareholders to obtain a premium for their shares of Common Stock and, accordingly, have a negative effect on the price of the Company.

If the amendment to the Restated Articles of Incorporation is approved, the Board of Directors generally may issue the additional authorized shares of Common Stock at any time for any proper corporate purpose without further shareholder approval. In some instances, shareholder approval for the issuance of additional shares may be required by the Wisconsin Business Corporation Law or the requirements of the Nasdaq National Market. Except in such cases, it is not anticipated that further shareholder authorization will be solicited.

The proposed amendment would amend and restate the first sentence of Article III of the Company’s Restated Articles of Incorporation to read as follows (proposed additions are indicated by underlining, and proposed deletions are indicated by overstriking):

The affirmative vote of a majority of the shares of the Common Stock represented and voted in person or by proxy at the Annual Meeting (assuming a quorum is present) is required for approval to adopt the amendment to the Restated Articles of Incorporation.

The Board of Directors recommends that you vote FOR adoption of the amendment to the Restated Articles of Incorporation.

Meetings of the Board of Directors and Committees of the Board of Directors

The Board of Directors held four regular meetings during 2002. During 2002, each Director attended at least 75% of the meetings of the Board of Directors and committees of the Board of Directors held during his or her tenure as a Director or committee member. The Board of Directors has standing Compensation, Audit, and Nominating and Corporate Governance Committees.

The Compensation Committee evaluates the performance of the Company’s executive officers, approves executive officer compensation and reviews management’s recommendations as to the compensation of other key personnel and makes recommendations to the Board of Directors regarding the types, methods and levels of Director compensation, administers the compensation plans for the officers, Directors and key employees, and discharges certain other responsibilities of the Board of Directors when so instructed by the Board of Directors. The members of the Compensation Committee are Messrs. Kearney (Chairman), Levy, Renwick and Seidman and Ms. Shackelford. The Compensation Committee held two meetings during 2002.

7

The Audit Committee’s primary function is to assist the Board of Directors in fulfilling its oversight responsibilities by reviewing the financial information, which will be provided to the shareholders and others, the systems of internal controls, which management and the Board of Directors have established, and the audit process. In doing so, it is the responsibility of the Audit Committee to provide an open avenue of communication between the Board of Directors, management, the Company’s internal audit function and the independent auditors. In connection with its responsibilities, the Audit Committee is directly and solely responsible for the appointment, compensation and oversight of the work of the independent auditors. The members of the Audit Committee are Messrs. Seidman (Chairman) Kearney, Renwick and Ms. Shackelford. The Audit Committee held five meetings during 2002.

The Nominating and Corporate Governance Committee assists the Board of Directors in identifying and evaluating potential nominees for a Directorship, and recommending qualified nominees to the Board for consideration. The Nominating and Corporate Governance Committee selects the Director nominees to stand for election at the Company’s Annual Meetings of Shareholders and to fill vacancies occurring on the Board. The Nominating and Corporate Governance Committee will consider nominees recommended by shareholders, but has no established procedures which shareholders must follow to make a recommendation. The Company’s By-laws also provide for shareholder nominations of candidates for election as Directors. These provisions require such nominations to be made pursuant to timely notice (as specified in the By-laws) in writing to the Chairman of the Board and/or President of the Company. In addition, the Nominating and Corporate Governance Committee oversees the corporate governance procedures of the Company. The members of the Nominating and Corporate Governance Committee are Ms. Shackelford (Chairman) and Messrs. Kearney, Levy, Renwick and Seidman. The Nominating and Corporate Governance Committee held one meeting during 2002.

Compensation of Directors

Directors who are officers or employees of the Company receive no compensation for service as members of the Board of Directors of the Company or for service on committees of the Board of Directors. A Director who is not an officer or employee of the Company receives an annual fee of $20,000 for service on the Board of Directors of the Company, plus $1,500 for attendance at Board of Director meetings and $400 for attendance at telephonic Board of Director meetings. Each outside Director is granted options to acquire, at the fair market value on the date of grant, 12,000 shares of Common Stock of the Company upon election to each new three-year term and 400 shares of Common Stock for attendance at each regular Board of Director meeting. The options granted vest 20% per year and expire 10 years from the date of the award.

Agreements with Executive Officers

The Company has in effect key executive employment and severance agreements (“KEESAs”) with certain executive officers of the Company, including Messrs. Muma, Dillon, Jensen, Balthasar and Schmelzer. The KEESAs provide that each executive officer who is a party thereto is entitled to benefits if, within three years after a change in control of the Company (as defined in the KEESAs), the executive officer’s employment is ended through (i) termination by the Company, other than by reason of death or disability or for cause (as defined in the KEESAs), (ii) termination by the executive officer for good reason (as defined in the KEESAs) or (iii) in the case of Messrs. Muma, Dillon, Jensen and Balthasar only, termination by the executive officer following the six-month anniversary of the change of control. The benefits provided are (i) a cash termination payment of two times the sum of the executive officer’s annual salary and his highest annual bonus during the three years before the change in control and (ii) continuation for up to three years of life, disability, hospitalization, medical and dental insurance coverage as in effect at the termination. Each KEESA provides that if any portion of the benefits under the KEESA or any other agreement for the executive officer would constitute an “excess parachute payment” for purposes of the Internal Revenue Code, then the executive officer will have the option either to receive the total payments and pay the 20% excise tax imposed by the Internal Revenue Code or to have the total payments reduced such that the executive officer will not be required to pay the excise tax.

Compensation Committee Report on Executive Compensation

In accordance with its written charter, the Compensation Committee of the Board of Directors is responsible for establishing compensation for the Company’s Chairman; President and Chief Executive Officer; Senior Executive Vice President and Chief Financial Officer; Senior Executive Vice President and Chief Operating Officer; and Corporate Executive Vice Presidents (the “Executives”). In so doing, the Compensation Committee has developed and implemented compensation policies and programs which seek to enhance the long-term profitability of the Company, thereby contributing to the value of shareholders’ investment.

Base Salary. Each Executive’s base salary is derived primarily through an analysis of appropriate industry and competitive labor markets for executive officers. Based upon the Company’s performance over the past five years when compared to companies comprising the S&P 500 and the Nasdaq Computer and Data Processing Services Industry Index, the Compensation Committee believes that the level of compensation for the Executives is commensurate with that which is being paid to senior executives by other companies in similar businesses.

Incentive Compensation Plan. For each of the Executives, a cash incentive compensation plan is established at the beginning of each fiscal year in connection with the establishment of the Company’s strategic plans and annual operating budgets. Each Executive’s plan establishes a range for incentive compensation and a number of performance objectives. The performance objectives generally include earnings per share growth, the financial performance of an Executive’s business unit, and/or various other measurable financial and non-financial objectives.

Stock Option Awards. In addition to annual cash compensation, the Compensation Committee establishes criteria pursuant to which the Executives may also qualify for the award of options to acquire the Company’s Common Stock at a price equal to the market value of the Common Stock on the date of grant. Awards are based 75% on growth in earnings per share and 25% on revenue growth. If the revenue growth percentage exceeds that for earnings per share, the earnings per share

11

growth percentage will replace the revenue growth percentage in determining awards. The minimum growth required to earn awards is 10% and the maximum annual award to any Executive is 1,012,500 shares.

Mr. Muma’s 2002 Compensation. Compensation for the Chief Executive Officer aligns with the philosophy and practices discussed above for the other senior executive officers. At the beginning of each year, the Compensation Committee sets a target bonus amount for the Chief Executive Officer. For compensation paid in 2002, Mr. Muma’s performance goals were established based on strategic and financial measurements, including a target level of earnings per share and implementation of the Company’s acquisition and internal growth strategies. Of these factors, the Company’s target level of earnings per share carried a significantly greater weight than the aggregate weight assigned to the remaining factors. Mr. Muma’s incentive compensation paid in 2002 reflects favorable achievement of the established performance objectives, particularly earnings per share and revenue growth, the key determinants of Mr. Muma’s incentive compensation. The Compensation Committee awarded Mr. Muma stock options in accordance with the criteria described above for other senior executives.

Section 162(m). Section 162(m) of the Internal Revenue Code limits the Company’s income tax deduction for compensation paid in any taxable year to certain executive officers to $1,000,000, subject to several exceptions. It is the policy of the Compensation Committee that the Company should use its best efforts to cause any compensation paid to Executives in excess of such dollar limit to qualify for such exceptions and, therefore, to continue to be deductible by the Company. In particular, the Company’s Stock Option Plan and Executive Incentive Compensation Plans were designed to permit awards made under the plans to qualify for Section 162(m)’s exception for “performance-based compensation.”
