The loans receivable, and the associated obligation to purchase those loans, are shown in Other long-term assets and Other long-term liabilities, respectively, on TVA's consolidated balance sheets. The current portion of the loans receivable and the associated obligation to purchase those loans are shown in Current assets and Current liabilities, respectively, on TVA's consolidated balance sheets. At December 31, 2012, the carrying amount of the loans receivable, net of discount, was approximately $152 million. The carrying amount of the associated obligation to purchase those loans was approximately $187 million.
