The American Hockey League (AHL) is a professional ice hockey league in North America that serves as the primary developmental circuit for the National Hockey League (NHL). 28 of the 30 NHL teams have exclusive affiliation agreements with one of the AHL's 29 active clubs. The first exception, the Dallas Stars, will have their own AHL affiliate for the 2009–10 season when the Texas Stars begin play.
The other, the Anaheim Ducks, have yet to announce which team or teams they intend to affiliate with in 2009-10. The league offices are located in Springfield, Massachusetts. Until the early 1990s, the headquarters were located in West Springfield, Massachusetts, along with charter member franchise, the Springfield Indians.
The AHL's current president is David Andrews. The annual playoff champion is awarded the Calder Cup, named for Frank Calder, the first President (1917–1943) of the NHL. The current champions are the Hershey Bears.
