What is my cost basis for a company that has merged twice since my purchase? Is it the original cost basis?

[Ashby · Accepted solution]

Your cost basis overall is the same as when you originally purchased. You may need to adjust your per share basis if you ended up with more shares post-merger(s). This may have been done for you. If not, you would simply figure out your total initial investment and divide by the number of shares you currently have.
