With no explanation, chose the best option from "A", "B", "C" or "D". is often, but not always, expressed as a percentage. Id. at 824. Interest, the court said, was broad enough to include non-percentage based charges. Although the court acknowledged that words contained in federal statutes are generally defined by federal common law, it determined that reference to state law was often appropriate. Resort to uniquely federal definitions is not, however, automatic. “Congress sometimes intends that a statutory term be given content by the application of state law.” Mississippi Band, 490 U.S. at 43, 109 S.Ct. at 1605. In such instances, a federal court may properly use state law to fill the interstices within a federal legislative scheme. See, e.g., Kamen [v. Kemper Fin. Servs., Inc., 500 U.S. 90, 107-09, 111 S.Ct. 1711, 1722-23, 114 L.Ed.2d 152 (1991) ] (<HOLDING>); Mississippi Band, 490 U.S. at 47-53, 109
