When must the authorization for an Entry processed by an RDFI have not been terminated?

The correct context for determining when the authorization for an Entry processed by a Receiving Depository Financial Institution (RDFI) must not be terminated is based on the stipulations of the National Automated Clearinghouse Association (NACHA) Operating Rules. These rules indicate that an authorization remains in effect until it is terminated, which can occur through various means.

While option B, "upon the operation of law," suggests that certain legal circumstances can dictate the termination of the authorization, it emphasizes that the authorization itself remains valid until a legal change or condition affects it. This typically covers situations like bankruptcy or other legal rulings that necessitate changes to existing agreements between a receiver and the RDFI.

Understanding the remaining contexts can provide further clarity: authorization can be revoked by the Receiver, but this does not mean it is inactive until the request is made, as seen in option A. Option C refers to the completion of the transaction, which could imply an action but does not inherently terminate authorization unless it specifically states so. The last option, which mentions the receipt of a notification, describes a scenario where the RDFI could be aware of a change rather than indicating an automatic termination.

Therefore, the focus is on when the authorization naturally extends until legally modified, thus
