Referees in the National Basketball Association (NBA) oversee 120 pre-season games, 1,260 regular season games, and four rounds of playoff matches. These officials "oversee competition in real-time between 10 exceptional athletes, making calls with 95% accuracy." In March 2015, the NBA began issuing Last Two Minutes reports that detail the performance of referees at the ends of games which the point differential is within five points with two minutes or less remaining in the contest.
