Answer:
The paying bank became accountable for the amount of the check when it held it longer than midnight on Wednesday, February 29, 2012. Its return of the check on March 5 is a late return. Assuming that the return was handled via the Federal Reserve, the depositary bank now has a window of two calendar months from the date of the return item cash letter to submit a late return claim via the Fed. After two months, you can make a without entry claim directly with the paying bank.
