The defendant, South Carolina Insurance Company, appeals from a judgment of the district court in a declaratory judgment action in which the court held that it had the primary exposure under its policy endorsement. The- facts are not in dispute. We think the court’s conclusions of law are correct and properly take into consideration the court’s obligation to construe the policy in the light of the public interest in insurance contracts.

The case involves the interpretation of an insurance contract under South Carolina law. Being a diversity action, state law controls and our decision will have limited precedential value. Since the case is one of first impression, we refrain from writing a full opinion in deference to the state court which must establish the controlling law.

Affirmed.
