I have finally started to do this. Thanks for your help by the way! When I go to http://otce.finra.org/DLSymbolNameChanges It only goes to 2012 in the date box. I have listed under "Undetermined Term Transactions for noncovered tax lots." I'll give you one example that I remember. I bought on 2/21/2007 INXR 1,000,000 shares That changed to INIX and 3 shares after splits. So I have this one figured out from memory and my records of purchases. But, I am trying to figure out what MCIC, PSTI, VCOC, ZNXT, RRRI were when I bought them...what was their original ticker symbol
