[5] Affiliated Computer Services, Inc. (ACS) was founded by Darwin Deason and Charles M. Young, both former MTech Communications executives, in 1988.

Two key developments were the acquisition of OBS Companies, a service provider with 200 employees and an annual revenue of $25 million, and a contract for the digitization of the Los Angeles County food stamp program.

ACS expanded beyond banking BPO services when it signed a 10-year data processing outsourcing contract with Southland Corporation (7-Eleven).

[6] In 2009, ACS ranked #401 on the FORTUNE 500 list and employed about 74,000 people around the world who served thousands of commercial and government clients.

[9] Xerox indicated that ITO did not line up with its vision of integration of BPO (business process outsourcing) and the legacy document handling concerns.

The lawsuit contended that some Xerox Corp directors and officers had abrogated their fiduciary duties in connection with the company's $6.4 billion acquisition of ACS in 2010.

[13] Throughout its history, ACS bought more than 50 businesses, the following is an overview of key acquisitions and joint-ventures: ACS began providing data processing and other information technology services to a single financial industry client, operating regionally from Dallas, and later added other banks and financial institutions to its list of clients.

[17] In 2006, the U.S. Securities and Exchange Commission (SEC) notified ACS that they were conducting an informal investigation into certain stock option grants made by the company from October 1998 through March 2005.
