In 2010, KSE exercised his right of first refusal to buy the remaining interest in the Rams from the estate of the late-owner Georgia Frontiere. On August 25, 2010, KSE became full owner of the Rams by unanimous consent of the NFL. To gain approval from NFL owners, KSE, with Stan Kroenke listed as the owner, agreed to turn over control of the Denver Nuggets and Colorado Avalanche to Josh Kroenke by the end of 2010, and for Stan Kroenke to give up his personal majority stakes in both teams in December 2014. The NFL does not allow its owners to hold majority control of major league teams in other NFL markets. On October 7, 2015, the NFL approved transfer of his ownership stake of the Avalanche and Nuggets to his wife, Ann Walton Kroenke.
