On Saturday April 24, 2021, Mr. Cooper discovered that its electronic payments vendor, ACI Worldwide, inadvertently issued incorrect mortgage payment drafts while conducting a test of their system. We immediately reported this error to our customers’ banks and worked with them to prevent any financial impact to our customer accounts by providing credits and reversing the incorrect drafts and fees which might have been charged. This was not a security breach, and Mr. Cooper did not receive any funds from customer accounts. As a result of our immediate action, as of Tuesday, April 27, out of 480,000 customers who could have been impacted, we are aware of approximately 100 customers who may have incurred nonsufficient funds fees as a result of ACI’s error, and we are in the process of reimbursing them for these fees. We are not aware of any customers for whom the incorrect drafts were not reversed.

The trust of our customers is more important to us than anything else. Upon discovering the payment processor’s error, we alerted customers through email, our website, social media posts, and our blog, and we have brought on extra staff at our call centers to answer customer questions. Any impacted customers will not be responsible for any fees or other charges they may have incurred.
