So that we don't kill IB's account management system with our 94,000 hits (all but 832 of ETs active members are IB customers, right?), the message I got was:
"Warning: Some of the cost basis calculations displayed on your 2007 annual statement are incorrect and a new annual statement will be generated for US customers by 03/10/2008 and for non-US customers by 03/28/2008.
The MTM & FIFO P/L calculations displayed are correct even for those transactions with an incorrect cost basis."
