Exhibit 99.1

XEROX AND ACS UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

On September 27, 2009, Xerox Corporation (“Xerox”) and Affiliated Computer Services, Inc. (“ACS”) entered into an Agreement and Plan of Merger providing for the acquisition of ACS by Xerox. Upon completion of the merger on February 5, 2010 (the acquisition date), ACS became a wholly owned subsidiary of Xerox.

The unaudited pro forma condensed combined balance sheet assumes that the merger took place on December 31, 2009 and combines Xerox’s audited December 31, 2009 consolidated balance sheet with ACS’s unaudited December 31, 2009 consolidated balance sheet.

The unaudited pro forma condensed combined statement of income for the fiscal year ended December 31, 2009 assumes that the merger took place on January 1, 2009. Xerox’s audited consolidated statement of income for the fiscal year ended December 31, 2009 has been combined with ACS’s unaudited consolidated statement of income for the four fiscal quarters ended December 31, 2009. This unaudited methodology includes the last two reported quarters of ACS’s fiscal year ended June 30, 2009 and ACS’s reported results for the six months ended December 31, 2009.

The historical consolidated financial information has been adjusted in the unaudited pro forma condensed combined financial statements to give effect to pro forma events that are (1) directly attributable to the merger, (2) factually supportable, and (3) with respect to the statement of income, expected to have a continuing impact on the combined results. The unaudited pro forma condensed combined financial information should be read in conjunction with the accompanying notes to the unaudited pro forma condensed combined financial statements. In addition, the unaudited pro forma condensed combined financial information was based on and should be read in conjunction with the following historical consolidated financial statements and accompanying notes of Xerox and ACS for the applicable periods:

The unaudited pro forma condensed combined financial information has been presented for informational purposes only. The pro forma information is not necessarily indicative of what the combined company’s financial position or results of operations actually would have been had the merger been completed as of the dates indicated. In addition, the unaudited pro forma condensed combined financial information does not purport to project the future financial position or operating results of the combined company. There were no material transactions between Xerox and ACS during the periods presented in the unaudited pro forma condensed combined financial statements that would need to be eliminated.

The unaudited pro forma condensed combined financial information has been prepared using the acquisition method of accounting under existing U.S. generally accepted accounting principles, or GAAP standards, which are subject to change and interpretation. Xerox has been treated as the acquiror in the merger for accounting purposes. The pro forma adjustments are preliminary and have been made solely for the purpose of providing unaudited pro forma condensed combined financial information. Although we do not expect any material adjustments, we expect to finalize these amounts during the second quarter of 2010. Under U.S. GAAP, companies have one year after an acquisition to finalize the purchase accounting. The following items still are subject to change:

The unaudited pro forma condensed combined financial information does not reflect any cost savings, operating synergies or revenue enhancements that the combined company may achieve as a result of the merger, the costs to combine the operations of Xerox and ACS or the costs necessary to achieve these cost savings, operating synergies and revenue enhancements.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1. Description of Transaction

Upon completion of the merger on February 5, 2010 (the acquisition date), ACS became a wholly owned subsidiary of Xerox as each share of ACS Class A and Class B common stock issued and outstanding converted into the right to receive a combination of 4.935 shares of Xerox common stock and $18.60 in cash, without interest. In addition, the holders of Class B common stock received shares of Xerox Convertible Preferred Stock (see below for description). The transaction qualified as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

ACS stock options, other than ACS stock options issued in August 2009, whether or not then vested and exercisable, became fully vested and exercisable and assumed by Xerox at the effective time of the merger in accordance with preexisting change-in-control provisions. Each assumed option became exercisable for Xerox common stock equal to the product of the number of shares of ACS Class A common stock that were subject to the ACS stock option immediately prior to the effective time of the merger multiplied by (i) the sum of (A) 4.935 and (B) the cash consideration of $18.60 divided by (ii) the per share closing price for Xerox common stock on the last trading day before the closing of this merger — such ratio the “Option Exchange Ratio.” The per share exercise price for the shares of Xerox common stock issuable upon exercise of the assumed ACS stock options is equal to the quotient determined by dividing the exercise price per share of ACS Class A common stock of the ACS stock option by the Option Exchange Ratio.

ACS stock options issued in August 2009 will continue to vest and become exercisable for Xerox common stock in accordance with their original terms. The estimated fair value of the new Xerox stock options will be recorded to compensation cost over the future vesting period. No adjustment to the unaudited pro forma condensed statement of income were made related to stock-based compensation since it is not anticipated that the stock-based compensation expense for ACS employees after the completion of the merger will be materially different than the amounts already included in ACS’s historical statements of income.

In connection with the merger, Xerox issued shares of Xerox Convertible Preferred Stock with an aggregate liquidation preference of $300 million to the holders of ACS Class B common stock. For purposes of these unaudited pro forma condensed combined financial statements, the Xerox Convertible Preferred Stock was estimated to have a fair value of $349 million. The Xerox Convertible Preferred Stock pays quarterly cash dividends at a rate of 8 percent per year and has a liquidation preference of $1,000 per share. Each share of Xerox Convertible Preferred Stock is convertible at any time, at the option of the holder, into 89.8876 shares of common stock (which reflects an initial conversion price of approximately $11.125 per share of common stock, which is a 25% premium over $8.90, which was the average closing price of Xerox common stock over the 7-trading day period ended on September 14, 2009, and the number used for calculating the initial conversion price in the merger agreement), subject to customary anti-dilution adjustments. On or after the fifth anniversary of the issue date, Xerox will have the right to cause, under certain circumstances, any or all of the Xerox Convertible Preferred Stock to be converted into shares of Xerox common stock at the then applicable conversion rate. The holders of Xerox Convertible Preferred Stock are also able to convert upon a change in control at the applicable conversion rate plus an additional number of shares determined by reference to the price paid for Xerox common stock upon a change in control. In addition, upon the occurrence of certain fundamental change events, including a future change in control of Xerox or if Xerox common stock ceases to be listed on a national securities exchange, the holders of Xerox Convertible Preferred Stock have the right to require Xerox to redeem any or all of the Xerox Convertible Preferred Stock in cash at a redemption price per share equal to the liquidation preference and any accrued and unpaid dividends to, but not including the redemption date. The Xerox Convertible Preferred Stock is classified as temporary equity (i.e., apart from permanent equity) as a result of the contingent redemption feature.

2. Basis of Presentation

The unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting and was based on the historical financial statements of Xerox and ACS. For ease of reference, all pro forma statements use Xerox’s period end dates and ACS’s reported information has been recasted accordingly to correspond to Xerox’s period end dates by adding ACS’s comparable quarterly periods as necessary. In addition, certain reclassifications have been made to the historical financial statements of ACS to conform with Xerox’s presentation, primarily related to the presentation of revenues; selling, administrative and general (SAG) expenses; software; intangible assets and deferred taxes.

The acquisition method of accounting is based on Accounting Standards Codification (ASC) Topic 805, Business Combinations, which Xerox adopted on January 1, 2009 and uses the fair value concepts defined in ASC Topic 820, Fair Value Measurements and Disclosures, which Xerox has adopted as required.

ASC Topic 805, requires, among other things, that most assets acquired and liabilities acquired be recognized at their fair values as of the acquisition date. Financial statements of Xerox issued after completion of the merger will reflect such fair values, measured as of the acquisition date. The financial statements of Xerox issued after the completion of the merger will not be retroactively restated to reflect the historical financial position or results of operations of ACS.

ASC Topic 820, defines the term “fair value” and sets forth the valuation requirements for any asset or liability measured at fair value, expands related disclosure requirements and specifies a hierarchy of valuation techniques based on the nature of the inputs used to develop the fair value measures. Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” This is an exit price concept for the valuation of the asset or liability. In addition, market participants are assumed to be unrelated (to Xerox) buyers and sellers in the principal (or the most advantageous) market for the asset or liability. Fair value measurements for an asset assume the highest and best use by these market participants. Many of these fair value measurements can be highly subjective and it is also possible that other professionals, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts. A single estimate of fair value results from a complex series of judgments about future events and uncertainties and relies heavily on estimates and assumptions. Our judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed as well as asset lives, can materially impact our results of operations.

Under ASC Topic 805, acquisition-related transaction costs (i.e., advisory, legal, valuation, other professional fees, etc.) not included as a component of consideration transferred but are accounted for as expenses in the periods in which the costs are incurred. The unaudited condensed combined pro forma financial statements assume that the estimated transaction costs remaining as of December 31, 2009 were paid in conjunction with the closing of the merger. Total advisory, legal, regulatory and valuation costs incurred by Xerox were $59 million, of which $14 million was expensed in the year ended December 31, 2009. In addition, Xerox has reflected fees of approximately $58 million associated with the bridge facility, as described in Xerox’s Current Report on Form 8-K filed on September 28, 2009, that were expensed in 2009. The bridge term facility was not utilized and was terminated in January 2010. The unaudited pro forma condensed combined balance sheet also reflects acquisition-related transaction costs incurred by ACS of $66 million as an assumed liability paid in connection with the closing of the merger (of which $21 million was expensed by ACS in 2009).

3. Accounting Policies

Xerox is still in the process of performing a detailed review of ACS’s accounting policies. At this time, Xerox is not aware of any differences that would have a material impact on the combined financial statements.

4. Consideration Transferred

The table below details the consideration transferred to acquire ACS (certain amounts reflect rounding adjustments):

5. Estimate of Assets Acquired and Liabilities Assumed

The following table provides an estimate of the assets acquired and the liabilities assumed by Xerox in the merger and represents ACS’s unaudited December 31, 2009 consolidated balance sheet adjusted for fair value and other acquisition related changes. The fair value and other acquisition related changes were determined as of the acquisition date.

Intangible Assets: The following table is a summary of the fair value estimates of the identifiable intangible assets and their weighted-average useful lives:

Deferred Revenue: Deferred revenue in the context of a business combination represents an obligation to provide future products or services to a customer when payment for such products or services has been made prior to the products being delivered or services rendered. A certain portion of ACS’s unearned revenue is for services already rendered and therefore no future obligation to provide services remains. The payments from customers were generally for up-front transition and set-up services and were deferred due to the revenue recognition requirements for up-front payments. Accordingly, Xerox adjusted the balance of unearned revenue by $133 million ($53 million current; $80 million non-current) for the estimated portion of unearned revenue for which no future service obligation remains. Post acquisition revenue will be reduced for the value of this adjustment. No adjustment was made for the remaining portion of unearned revenue of approximately $161 million ($145 million current; $16 million non-current) as it was determined to be a reasonable estimate of the fair value for the remaining obligation to provide future services to customers.

Deferred Taxes: For purpose of these unaudited pro forma condensed combined financial statements, we provided deferred taxes and recorded other tax adjustments of $385 million ($54 million current; $331 million non-current) as part of the accounting for the acquisition. After the adjustments, the estimated net deferred tax liability was $987 million as of December 31, 2009 ($151 million current; $836 million non-current). The adjustments primarily related to the estimated fair value adjustments for acquired intangible assets as well as the elimination of a previously recorded deferred tax liability associated with ACS’s historical goodwill that was tax deductible. In addition, we also provided deferred taxes of $76 million for the outside basis difference associated with certain foreign subsidiaries of ACS for which no taxes have been previously provided. We expect to reverse the outside basis difference primarily through our current intention to repatriate earnings from those subsidiaries as opposed to permanently reinvesting them as well as through the reorganization of those subsidiaries. See Note 7 Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheets, item (G) for details regarding the adjustment to deferred taxes.

Debt: As of the effective time of the merger, debt must be measured at fair value. A portion of ACS’s debt was repaid in connection with the closing of the merger - $1,767 million at December 31, 2009 - together with related interest rate swaps representing a $26 million liability at December 31, 2009. Accordingly, Xerox only calculated a fair value adjustment to ACS’s remaining debt. As a result of the debt repayment and fair value adjustment, ACS’s deferred debt issuance costs of $19 million were written off. The following is a summary as of December 31, 2009 of the ACS debt assumed:

Pension Obligations: In connection with our acquisition of ACS, we assumed several pension plans covering the employees of ACS’s human resources consulting and outsourcing business in the U.S., U.K., Germany and Canada. The plans in the U.S. and Canada are both funded and unfunded; the plan in the U.K. is funded and the plan in Germany is unfunded. The following is a summary of the estimated funded position of the assumed ACS plans, as well as associated weighted-average assumptions used to determine benefit obligations for purposes of these unaudited pro forma condensed combined financial statements:

Amounts recognized in the unaudited pro forma condensed combined balance sheet:

Weighted average assumption used to determine benefit obligations:

Other Long-Term Liabilities: The assumed liabilities include payments due under contractual change-in-control provisions in employment agreements of certain ACS employees and its Chairman of approximately $95 million ($15 million current; $80 million non-current). The liabilities include accruals for related excise and other taxes Xerox is obligated to pay. This amount is a preliminary estimate that may change once the underlying calculations are finalized and excludes $11 million of change-in-control related payments made in October 2009.

Contingent Consideration: Although there is no contingent consideration associated with this merger, ACS is obligated to make certain contingent payments in connection with prior acquisitions upon satisfaction of certain contractual criteria. As of the effective time of the merger, contingent consideration obligations must be recorded at their respective fair value. As of December 31, 2009, the maximum aggregate amount of ACS’s outstanding contingent obligations to former shareholders of acquired entities is approximately $46 million. The fair value of this obligation was estimated to be $11 million ($9 million current; $2 million non-current) for purposes of these unaudited pro forma condensed combined financial statements.

Contingencies: As of the effective time of the merger, except as specifically excluded by GAAP, contingencies are required to be measured at fair value, if the acquisition-date fair value of the asset or liability arising from a contingency can be determined. If the acquisition-date fair value of the asset or liability cannot be determined, the asset or liability would be recognized at the acquisition date if both of the following criteria were met: (i) it is probable that an asset existed or that a liability had been incurred at the acquisition date, and (ii) the amount of the asset or liability can be reasonably estimated. These criteria are to be applied using the guidance in ASC Topic 405, Contingencies. ACS is involved in various legal proceedings, including an SEC investigation. However, Xerox is still reviewing information regarding the fair value of these contingencies. A fair valuation effort requires review of complex legal matters and associated defense strategies, which are in progress. As required, ACS has historically accounted for these contingencies under ASC Topic 405. If fair value cannot be determined for ACS’s contingencies, the combined company would continue to account for the ACS contingencies using ASC Topic 405. For the purpose of these unaudited pro forma condensed combined financial statements, Xerox has not adjusted the ACS book values for contingencies. This approach is preliminary and subject to change after completion of the final review and assessment of ACS’s legal proceedings.

Goodwill: Goodwill in the amount of $5.1 billion is estimated for this acquisition and is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Specifically, the goodwill recorded as part of the acquisition of ACS includes:

Goodwill is not amortized but rather subject to an annual fair value impairment test. Goodwill of $2.28 billion is estimated to be deductible for tax purposes as a result of being generated from previous taxable acquisitions of ACS.

6. Notes to Adjustments to Unaudited Pro Forma Condensed Combined Statements of Income

(A) Reflects adjustments for the following (in millions):

(B) Reflects adjustments for the following (in millions):

(C) The pro forma adjustment to other expenses, net primarily reflects additional intangible asset amortization and the interest expense related to the Senior Notes Xerox issued in December 2009 and $649 million of additional borrowings under our existing revolving credit facility. The components of the adjustments to other expenses, net are as follows (in millions):

(D) This represents the tax effect of adjustments to income before income taxes and equity income primarily related to the expense associated with incremental debt to partially finance the merger and increased amortization resulting from estimated fair value adjustments for acquired intangibles, as well as fair value adjustments including those for unearned revenue, software and land, buildings and equipment. Xerox has assumed a 38% blended tax rate representing the estimated combined effective U.S. federal and state statutory rates. This estimated blended tax rate recognizes that ACS is predominately a U.S. based entity and that the debt incurred by Xerox to effect the merger is an obligation of a U.S. entity. However, the effective tax rate of the combined company could be significantly different (either higher or lower) depending on post-acquisition activities.

(E) The unaudited pro forma condensed combined basic and diluted earnings per share calculations are the historical basic and diluted weighted average shares of Xerox plus the shares issued by Xerox to effect the merger and the effect of Xerox stock options issued in exchange for the ACS options. For purposes of the unaudited pro forma condensed combined diluted earnings per share calculations, net income available to common shareholders reflects net income less dividends on the Series A convertible preferred stock of $24 million per year.
