I ran into a case in PortfolioCenter where the Cost Basis Reconciliation report showed a negative cost basis for several positions that had been sold. Now what?

The report looked listed 0.00 shares with a negative cost basis in PortfolioCenter (above).

The problem results from ROP transactions that hit the account after the mortgaged backed position had been sold.

To solve the problem:
- Cancel the sell.
- Change the date of the Interest and ROP to the day before the sell.
- Repost the sell.
