In my experience, most of the majors transfer cost basis info.  But that’s assuming that they had it to begin with.  If the stocks have been held for a long time, and were purchased at another firm, chances are they won’t have the cost basis, so they can’t transfer it.

Thanks B24 for the post.  Just based on experiences from what Advisors have told me, it appears cost-basis issues are at times difficult with Pershing, LLC., and TDAmeritrade.  I’m not sure why on the TD side but at Pershing, depending on the B/D – I remember the days when either the client or the advisor had to pay Pershing something like $2/account per month in order to maintain cost-basis.  Again, it depends on the B/D contract with Pershing.  NFS/Fidelity I recall does maintain cost-basis but one experience I remember working at a B/D if the Advisor wanted the cost-basis printed on the statement, they had to pay something like 70 cents per account per month to have it printed.  I agree, it seems everyone can maintain it but its more important on what the contract between the B/D and the clearing firm allow or support.
