BrendaC - really? We went to the mat on that one, with an external auditor. We pointed to the regulation, which says the recordkeeping requirements kick in when the instrument is purchased with currency. If you swap a check for a check, the new check you create is not a "monetary instrument" as referred to in the below reg, because it was not purchased with currency, in my opinion.
