EDS

IT services company started by Ross Perot in 1962.

General Motors acquired the company in 1984, spun it off again as an independent company in 1996, and became an EDS client.

EDS formed the National Heritage Insurance Company in 1996. The creation of this subsidiary is to manage Medicare Part B services on behalf of the Centers for Medicare and Medicaid Services (CMS), formerly the Health Care Financing Administration (HCFA). NHIC handles call center, claims processing and payment, fraud investigations, physician enrollment etc. in many states of the US.

Another large EDS client is the United States Navy. In 2000, they won a contract for the creation of a US$9 billion intranet linking the Navy and the Marine Corps, which was set to late 2006, but on March 24, 2006 was extended to 2010, adding $3 billion to the accumulated contract worth.
