Transfers and Servicing [Abstract]
Private Education Loan Term Securitizations	Private Education Loan Term Securitizations We securitize Private Education Loan assets by selling these assets to securitization trusts. If a transfer of loans qualifies as a sale, we derecognize the loan and recognize a gain or loss as the difference between compensation received and the carrying basis of the loans sold and liabilities retained. We recognize the results of a transfer of loans based upon the settlement date of the transaction. If we have a variable interest in a VIE (e.g., a securitization trust) and have determined that we are the primary beneficiary, then we will consolidate the VIE and the transfer is accounted for as a financing as opposed to a sale. On May 26, 2016, we executed a $551 million Private Education Loan Trust term ABS transaction that was accounted for as a secured financing. We retained a 100 percent or $50 million interest in the Class B notes and 100 percent of the residual certificates issued in the securitization. $501 million of Class A notes from the securitization were sold to third parties, raising $501 million of gross proceeds. At June 30, 2016, $583 million of our Private Education Loans were encumbered as a result of this transaction.
