What does the phrase " subject to origination restriction" mean?

The phrase "…subject to origination restriction" refers to a restriction imposed upon withdrawals of funds that were deposited via an ACH or EFT and initiated through your MEXEM account. Funds transferred in this manner are subject to clawback by the sending institution in the event of fraud or error. As the length of this clawback period is extensive, clients are restricted from withdrawing the funds to anywhere other than the bank from which they originated for a period of 44 business days after deposit (60 business days in the case of Canadian EFT deposits). ACH and EFT deposits may be withdrawn after the initial 4 business day credit hold has expired if sent back to the originating bank.
