FAQ: Frequently Asked Questions

Xerox Agrees to Acquire Affiliated Computer Services

Why did Xerox decide to purchase ACS?

This transaction will combine Xerox’s strengths in document technology and services with ACS’s expertise in managing and automating work processes, creating the leading global enterprise for comprehensive document and business process management.

Business process outsourcing is estimated to be a $150 billion market, growing at a rate of 5 percent per year. Combined, we’ll pursue a $500 billion market, and we will instantly be a leader in key segments of this market, with solutions centered around the information needs of business processes, not solely the software applications or IT infrastructure.

By acquiring ACS, Xerox will triple the revenue it generates from services, from $3.5 billion in 2008 to an estimated $10 billion in 2010. With a total combined revenue of $22 billion, the acquisition significantly expands Xerox business through revenue and earnings growth.

What are the terms of the acquisition?

Xerox and ACS have signed a definitive agreement for Xerox to acquire ACS in a cash and stock transaction valued at $63.11 per share or $6.4 billion as of the closing price of Xerox stock on Sept. 25. ACS shareholders will receive a total of $18.60 per share in cash plus 4.935 Xerox shares for each ACS share they own. In addition, Xerox will assume ACS’s debt of $2 billion and issue $300 million of convertible preferred stock to ACS’ Class B shareholder.

Who is ACS?

The world’s largest diversified business process outsourcing (BPO) firm, ACS is a $6.5 billion company with revenue growth of 6 percent and new business signings of $1 billion in annual recurring revenue during its fiscal 2009.

ACS’s expertise is in managing and automating paper-based work processes and providing BPO services that range from processing over 1 million credit card applications each year to handling more than 1 million phone calls each day in its 140 customer care centers. Through its multi-year contracts that include processing annually $3 billion in electronic toll collections and claims from 36 million Medicaid recipients, ACS is the largest provider of managed services to government entities in the U.S.

ACS is comprised of five business groups supporting client operations worldwide:

• Business Process Solutions delivers high-volume transaction processing and customer care solutions.

• Commercial Solutions provides finance and accounting, human management capital solutions, and education and financial services.

• The Government Solutions group is one of the largest business process solution providers and IT service providers to the nations’ public sector.

• Information Technology Outsourcing provides IT services and support to commercial clients.

• Transportation Solutions is the largest provider of transportation services to governments worldwide through fare collection, toll solutions, back-office processing and infrastructure installations.

How will ACS operate as part of Xerox?

ACS will be an independently run Xerox organization and will serve as Xerox’s core BPO business. It will operate as ACS, a Xerox Company, led by current ACS CEO Lynn Blodgett, who will report to Xerox CEO Ursula Burns.

What synergies will result from the Xerox acquisition of ACS?

Revenue growth synergies: Xerox will achieve significant incremental revenue growth by leveraging Xerox’s strong global brand and established client relationships to scale ACS’s business in Europe, Asia and South America. In addition, Xerox will integrate its intellectual property with ACS’s services to create new solutions for end-to-end support of customers’ work processes.

Cost reduction synergies: Xerox expects to achieve annualized cost synergies that will increase to the range of $300 million to $400 million in the first three years following the close of the transaction. The synergies are primarily based on expense reductions related to public company costs, procurement and using ACS’s expertise in back-office operations to handle some of Xerox’s internal functions.

Why did Xerox choose ACS?

Xerox has built a successful business as the industry’s leader for document technology and services. We’ve been modestly participating in the related business process outsourcing market, which is often dependent on document management, especially automating paper-based work processes. Through our strategic initiatives, it became clear that this is a growth market most aligned with our base business and most critical to our long-term growth opportunities.

ACS has successfully built its $6.5 billion business by developing BPO offerings that automate document-intensive work processes and seamlessly connect paper and digital data. As the lines blur between core document management and document-intensive BPO, our companies identified an opportunity to combine our strengths and create the leading global enterprise for comprehensive document and business process management.

For Xerox, this transaction helps us significantly expand our business and benefit from stronger revenue and earnings growth.

ACS will be better positioned to scale its business globally by leveraging Xerox’s brand strength, global account management, deep sales relationships with governments and large enterprises, and by applying Xerox’s intellectual property in document solutions to its BPO offerings.

Will Xerox’s existing managed print services become part of ACS?

No. Our managed print services are closely tied to our technology offerings and will continue to be a key growth strategy for our core business going forward.

Will Xerox start using ACS offerings internally, like IT and call center support?

Both companies have key offerings that complement each other. A transition team will focus on if and how we apply these services to Xerox’s existing operations.

How will this impact Xerox’s alliance partnerships with IBM, CSC and others that compete with ACS?

We intend to continue these relationships. Xerox has a broad managed print services capability that is a natural alignment with the offerings of these partners.

When is the transaction expected to close?

The transaction is subject to customary closing conditions including domestic and foreign regulatory approvals as well as the approval of shareholders. It is expected to close in early 2010.
