STOCKHOLM, Sept 15 (Reuters) - Autoliv , the world's biggest maker of air bags and seat belts, said on Tuesday a U.S. court had confirmed it must pay damages to a former supplier which could total $36 million. Autoliv said the damages relate to commercial agreements made by subsidiary Autoliv ASP, Inc. in 1995. In an initial ruling in 2003, a district court awarded the supplier around $27 million in damages and $7 million in interest.
