The bank named in a letter of credit from which the paying, accepting or negotiating bank may request cover after receipt of the documents in compliance with the letter of credit. The reimbursement bank is often but not always, the issuing bank. If the reimbursement bank is not the issuing bank, it does not have a commitment to pay unless it has confirmed the reimbursement instruction. The issuing bank is not released from its commitment to pay through the nomination of a reimbursement bank. If cover from the reimbursing bank should not arrived in time, the issuing bank is obliged to pay (also any accrued interest on arrears).
