 Beginning with the 2005 – 06 season , the NHL instituted several new rules . Some of them were already used by the IIHF , such as the shootout and making the two @-@ line pass legal . Others which were not picked up by the IIHF , such as requiring smaller goaltender equipment and the addition of the goaltender trapezoid to the rink . However , the IIHF did agree to follow the NHL 's league 's zero @-@ tolerance policy on obstruction and required referees to call more hooking , holding and interference penalties . In 2006 , the IIHF voted to eliminate tie games and institute a three @-@ point system : wins in regulation time would be worth three points , overtime wins would be two points and over @-@ time losses would be worth one point . The system was first used at the 2007 World Championships .
