 Ostensibly, USAS will "sign off" on the selections of an NGB's delegation to an international competition (whether hosted by the IOC, FINA, or ASUA).USAS hosts an annual convention where the five NGBs meet, as well; currently this meeting also includes the annual conventions for all but water polo--who is in-season at the time, and instead holds its annual convention at another time of the year.The reasoning behind this is to allow the NGBs to save money on their national conventions and to allow collaboration between the NGBs on common issues of interest.
