Good point, and one I keep running into. I'm auditing our DDA recoveries department. Suppose that it's the final day before the overdrawn account is charged off, and a payment comes in. But instead of being stamped as received on the day it is reveived by the bank, it is not stamped as received until two days later, when it actually makes it to the recoveries department. Unlikely, yes, but possible. Just covering all my bases (I hope). On top of that, difference or not, the audit is for compliance with federal requirements - that's my real goal.
