Hi, Mark!
I have some examples where the Tax Basis value in the Open Lots report isn't exactly equal to the Value dollar amount of the transaction. It has the appearance of some sort of round-off issue - the discrepancy begins in the third or fourth decimal place. I'm finding it only in older transactions.
I'd be happy to send you anything you'd find useful. Just let me know what to package up.
Thanks, and all the best,
Dan Konigsbach
