Key: Legal successor and corporate names. 

- EDS was sold to the Hewlett-Packard Company on Aug 26, 2008. EDS stock peaked at $50 to $72 in 2001 but was down to $19 before the announcement. HP paid $25 per share in cash, $13.9 billion -- a 32% premium.

- HP Inc. is the legal successor to the companies acquired by the Hewlett-Packard Company before the company was split into HP Inc. and Hewlett Packard Enterprise (HPE.) Responsibility for any commitments to former employees of Autonomy, Compaq, Digital, EDS, Tandem, etc. remain with HP Inc. -- regardless of whether the employee's last business unit ended up in HP Inc. or HPE. This includes employment verification and any retiree health coverage, pension, 401(k), etc. plans. HPE is responsible for any commitments to former employees of companies acquired by HPE, such as Cray, Nimble, etc.

- EDS was temporarily structured as a wholly-owned subsidiary called "EDS, an HP Company." On Sep 23, 2009, it was renamed "HP Enterprise Services."

- On Oct 21, 2015, Hewlett-Packard Company spun off Hewlett Packard Enterprise (no hyphen; singular.)

Which HP-related companies am I a retiree or former employee of? (Not always obvious.) Given HP's complex history of acquisitions, divestitures, and spinoffs, the company or companies that you are legally a former employee of may not be obvious. If any doubt, check here: Which Company

Make sure that every company you ever worked for has your current postal address. Even if not classified by the company as a "Retiree" or if long gone -- in case of pension plan changes, employment lawsuits, settlements, or other issues. (HP Inc. is the legal successor to companies bought by HP -- including Compaq and EDS. HPE is successor to companies it bought -- Cray, Nimble, etc.) Update address at former company

Service at predecessor companies. Of HP's many predecessor companies, only HP and DEC had retiree healthcare programs. Only HP, Digital, and EDS had pension plans. Over the years, HP, DEC, and EDS set aside money in dedicated trust funds to pay for those programs. Compaq, Tandem, Autonomy, Palm, etc. did not have retiree healthcare or pensions among their benefits programs. Their employees did not have those expectations and there were no corresponding trust funds to pass on to an acquiring company. Therefore, employees of those companies do not get credit under HP's retiree healthcare or pension programs for service at the predecessor company. (DEC employees get retiree health credit for DEC and HP service but not Compaq service.) Confusingly, predecessor service counts for vacation/FTO.
