That transaction occurred months before Mark Cuban, owner of the NBA's Dallas Mavericks, sold a majority interest in the franchise to Miriam Adelson, the widow of late Las Vegas Sands Chairman and CEO Sheldon Adelson, and her family. The NBA approved Cuban's sale on December 27. Patrick Dumont, Miriam Adelson's son-in-law and president and COO of the Las Vegas Sands, will serve as the Mavericks governor (Cuban will still retain authority over the team.)
