arrangement, CUNA Mutual Group mortgage insurance sales staff will continue to
serve credit union customers on behalf of CMG MI.

this unique business," said Sean Dilweg, CUNA Mutual Group vice president and
product executive for CMG MI. "We are confident Arch U.S. MI more than
fulfills all of these requirements."
