I received 200 shares of Paramount Global on January 21, 2015. I sold these shares on 8/29/2025.
My 1099-B does not identify a cost basis for these non-covered securities. As an aside, I do have cost basis information on the 1099-B for covered Paramount Global securities.
The stock sold has had an interesting journey. It has a genealogy of Gulf and Western, CBS and Viacom. At some point, Viacom acquired Paramount Communications. At some point, Viacom acquired CBS. In about 2006, Viacom and CBS split into two distinct companies. In 2019, CBS and Viacom merged and assumed the name ViacomCBS. In 2022, the company was renamed Paramount Global.
I am sure this has been asked before and my apologies for re-asking. What is an IRS acceptable practice to use to identify cost basis for these shares?
