NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Principles of Consolidation

The condensed consolidated financial statements for the three and six month periods ended June 30, 2005 and 2004 are unaudited. In the opinion of management, all adjustments necessary for a fair presentation of such condensed consolidated financial statements have been included. Such adjustments consisted only of normal recurring items. Interim results are not necessarily indicative of results for a full year. The financial statements and notes are presented as permitted by Form 10-Q, and do not contain certain information included in the annual consolidated financial statements and notes of Fiserv, Inc. and subsidiaries (the “Company”). It is recommended that these interim condensed consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2004. Certain prior period amounts have been reclassified to conform to the current period presentation. See the Company’s results by business segment in Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

2. Recent Accounting Pronouncement

In December 2004, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), “Share-Based Payment” (“SFAS 123R”), that requires companies to expense the value of employee stock purchase plans, stock option grants and similar awards. In April 2005, the Securities and Exchange Commission (“SEC”) announced the adoption of a new rule that amends the compliance dates for SFAS 123R. The new rule allows companies to implement SFAS 123R at the beginning of their next fiscal year, instead of the next reporting period, that begins after June 15, 2005. The new rule does not change the accounting required by SFAS 123R; it only changes the date for compliance with the standard. The Company will adopt SFAS 123R on January 1, 2006 and continues to evaluate the impact that the adoption of the final standard will have on the Company’s financial statements.

3. Discontinued Operations

On March 24, 2005, the Company completed the sale of its securities clearing businesses to Fidelity Global Brokerage Group, Inc. for $344.9 million paid in cash at closing, subject to certain post-closing adjustments. Prior to completion of the sale, the securities clearing businesses paid a $68.0 million cash distribution to the Company. The sales proceeds, net of related expenses, including taxes that became due upon the sale of the securities clearing businesses, approximated the Company’s carrying value of its investment. The stock purchase agreement also provides for a contingent payment of up to $15.0 million to be paid after the first anniversary of the closing date based on achievement of certain revenue targets. In addition, as part of the stock purchase agreement, the Company retained the liability associated with the SEC investigation of the mutual fund trading practices of the securities clearing businesses. In April 2005, Fiserv Securities, Inc. settled with the SEC on this matter for $15.0 million, which was fully accrued for in the Company’s 2004 financial statements.

The Company’s securities clearing businesses have been reported as discontinued operations for all periods presented and are excluded from reported revenue, cost of revenues and operating cash flows. Summarized financial information for discontinued operations included in the financial statements for the three and six month periods ended June 30, 2005 and 2004 was as follows:

4. Long-Term Debt

The Company has a credit facility totaling $700.0 million, which is comprised of a $465.3 million five-year revolving credit facility due in 2009 and a $234.7 million 364-day revolving credit facility that is renewable annually through 2009. The Company must, among other requirements, maintain a minimum net worth of $1.9 billion as of June 30, 2005 and limit its total debt to no more than three and one-half times the Company’s earnings before interest, taxes, depreciation and amortization. The Company was in compliance with all debt covenants at June 30, 2005.

5. Stock-Based Compensation

The Company has accounted for its stock-based compensation plans in accordance with the intrinsic value provisions of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees.” Accordingly, the Company did not record compensation expense in the condensed consolidated financial statements for its stock-based compensation plans.

The following table illustrates the effect on net income and net income per share had compensation expense been recognized consistent with the fair value provisions of SFAS No. 123, “Accounting for Stock-Based Compensation” (“SFAS 123”). The fair value of each option issued prior to January 1, 2004 was estimated on the date of grant using a Black-Scholes option-pricing model. For options granted on or after January 1, 2004, the fair value of each option was estimated on the date of grant using a binomial option-pricing model. Stock options are typically granted in the first quarter of the year, generally vest 20% on the date of grant and 20% each year thereafter and expire 10 years from the date of the award. As a result, the expense that would be recognized under SFAS 123 during the first quarter is significantly higher than the expense for the remaining quarters. The calculated expense for the six month period ended June 30, 2005 was higher than the expense in the comparable period in 2004 as certain participants met accelerated vesting provisions stipulated in the stock option agreements related to age and years of service with the Company in the first quarter of 2005.

6. Shares Used in Computing Net Income Per Share

The computation of the number of shares used in calculating basic and diluted net income per share is as follows:

7. Comprehensive Income

Comprehensive income consists of net income, unrealized gains and losses on available-for-sale investment securities, foreign currency translation and fair market value adjustments on cash flow hedges and is as follows:

The components of comprehensive income for the six month period ended June 30, 2005 was negatively impacted by the realized gain on the sale of the Company’s remaining ownership of 3.2 million shares of Bisys Group, Inc. common stock that was recorded in the first quarter of 2005.

8. Subsequent Event

On July 27, 2005, the Company signed a definitive agreement to acquire BillMatrix Corp. for a total purchase price of approximately $350 million. The transaction is expected to close in the third quarter of 2005.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Results of Operations

The Company is an independent provider of financial data processing systems and related information management services and products to financial institutions, other financial intermediaries and employers who self-insure their health plans. The Company’s continuing operations are classified into three business segments: Financial institution outsourcing, systems and services (“Financial”); Health plan management services (“Health”); and Investment support services (“Investment”).

The following tables and discussion exclude the revenues and expenses associated with customer reimbursements because management believes that it is not appropriate to include customer reimbursements in analyzing the current performance of the Company as these balances offset in revenues and expenses with no impact on operating income and these amounts are not an indicator of current or future business trends. Customer reimbursements, which primarily consist of pass-through expenses such as postage and data communication costs, were $83.3 million and $89.9 million for the three month periods ended June 30, 2005 and 2004 and $174.1 million and $187.3 million for the six month periods ended June 30, 2005 and 2004, respectively. The following tables present, for the periods indicated, certain amounts included in the Company’s condensed consolidated statements of income, the relative percentage that those amounts represent to processing and services revenues, and the change in those amounts from period to period.
