Course descriptions

ICB Credit: 2.5 CRCM

This three-part webinar series is designed specifically for banks. Each session builds off the last, providing attendees with ACH essentials.

This webinar, the third in the series, explores ACH pre-notifications, returns and reversals from the perspective of how each affects the RDFI and the ODFI. Some discussions will also include how the actions (or inactions) of an Originator affect the ODFI's liability and responsibility. We will walk through potential pitfalls, risks, and compliance obligations when handling daily situations.

Attendees will have the opportunity to test their new skills against common scenarios, with an emphasis on scenarios that are often handled incorrectly, resulting in non-compliance, increased risk and even preventable loss.

Attendees will receive a FREE Guide to Navigating the ACH Rules Book.

Note: Have your 2017 NACHA Operating Rules and Guidelines book (aka, ACH Rules) handy! If you do not have an ACH Rules book, please contact your regional payments association, order from, or contact Janet Merlet at NEACH, and mention promo code rppaymentsrisk to receive a 15% discount when ordering.

The instructor will be providing page numbers for your reference throughout the program, so you might want a highlighter handy as well.
