One of the main changes was changes in reporting. From now on, only reports sent by email will be accepted. It is also required to provide reporting on blocked property that is unblocked or transferred within 10 business days from the date of unblocking or transfer of property.
Transactions that must be reported include those involving securities, checks, foreign exchange, and the sale or purchase of goods or services. If the information required by OFAC is not available at the time the transaction is rejected, providing that information is not required.
