Arizona State University has reached a 15-year naming rights deal with Mountain America Credit Union that changes Sun Devil Stadium to  Mountain America Stadium, Home of the ASU Sun Devils.

Financial details of the deal were not initially disclosed by ASU.

"The ability to compete at a high level during a transformational time in college athletics requires finding incredible partners who want to invest in our 26 sports, our 650 student-athletes and our 300-plus staff and coaches," Ray Anderson, Sun Devil vice president for university athletics, said Wednesday.

"An athletic department of nearly 1,000 team members requires incredible amounts of technology, nutrition, mental health resources, travel and other vital parts to win championships.”

ASU President Michael Crow called it "one of the important naming rights deals in the history of college sports.”

"This new partnership allows Mountain America to support hundreds of student-athletes and the Arizona community for many years to come through enhanced financial education, scholarship, internship and cause marketing programs," said Sterling Nielsen, president and CEO at Mountain America Credit Union.

The deal comes as ASU finds itself in the middle of what could be a breakdown in the PAC 12 over media rights. The conferences nine remaining members have one year to go on the deal that pays them millions, but have struggled to secure partnerships with major broadcasters.

Media deals, in the tens of millions of dollars annually, are key contributors to universities' athletic departments. The University of Colorado announced its intention to leave the PAC 12 last week to join the Big 12 and secure about $31 million in annual media licensing.
