If you issue non-negotiable CD's, do still hold them in safekeeping? We discontinued this practice, therefore, have very few items in collateral safekeeping. For the remaining items however, you should be issuing pre-numbered safekeeping receipts. Those receipts should be periodically reconciled to the physical items held. The numerical integrity of the receipts should be maintained as they are issued and when items are released. Trace receipts indicating released collateral to paid loan or replacement.
Other controls such as adequacy of storage facility, adherence to and effectiveness of dual control and documentation of access should also be reviewed.
For CD's, since we no longer hold in s/k, I gen and cross reference a report using collateral code to identify all loans secured by CD's and a report of CD's with a hold and related loan # and verify.
