HP Breakup. On Nov 1, 2015, the legal name of the Hewlett-Packard Company was changed to HP Inc. and a new, completely separate company – Hewlett Packard Enterprise (no hyphen; singular; green-rectangle logo) – was spun off. Portions of HPE were later spun off into DXC and Micro Focus. Details: HP Breakup 

HP Inc. is the legal successor to Hewlett-Packard and to companies acquired by Hewlett-Packard before Nov 1, 2015 – such as Compaq, DEC, EDS, Tandem, etc. For employees of HP -- and predecessor companies -- who left before the split, responsibility for any health or retirement benefits varies from country to country. For the US, HPInc has responsibility. For Canada and UK, HPE has responsibility. In many countries, plans were split between HPInc and HPE. See: Country-by-country details
