Stock:

You may now have stock in HP, HPE, Agilent, Keysight, or DXC in various accounts – and may not have received cash payouts for Micro Focus or Perspecta.

Members have found that plan administrators, transfer agents, and brokerages vary significantly in how (or if) they track gain/loss and cost basis for the many complex HP-related stock events -- and what (if anything) they report to the IRS.

HP had a page on their financial website entitled "Q and A," which linked to FAQs giving details for stockholders of companies that HP had acquired.
