Paying agent
From ACT Wiki
In respect of a bond, an institution, a company or a bank which, on behalf of the issuing company that appoints it, makes interest payments and repayment of the principal upon presentation of coupon and/or bond certificates.
The term paying agent is usually used where the bond also has trustee who represents the interests of the bondholders. Where there is no trustee, the agent is commonly referred to as a "fiscal agent".
