Vineyard Coal Company and Crounse Corporation appeal from summary judgment in favor of Citizens Fidelity Bank & Trust Company. Vineyard had claimed that it was entitled to the proceeds of certain coal contracts between it and the Tennessee Valley Authority, to which Citizens claimed a superior perfected security interest. Crounse had sought demurrage and towage charges related to transporting coal under those contracts. Having heard oral argument from counsel for the parties, and upon consideration of the record and briefs, we affirm the judgment of the district court for the reasons stated in its memorandum opinion of June 22, 1987.
