Transfers and Servicing of Financial Assets [Abstract]
Private Education Loan Securitization	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 July 30, 2015, we executed a $714 million Private Education Loan term ABS transaction that was accounted for as an on-balance sheet secured financing. We retained a 5 percent interest in the Class A and B notes, a 100 percent interest in the Class C notes and 100 percent of the residual certificates issued in the securitization. $631 million of notes were sold to third parties, raising $623 million of gross proceeeds. At September 30, 2015, $692 million of our Private Education Loans are encumbered as a result of this transaction. On April 23, 2015, we sold $738 million of Private Education Loans through a securitization transaction to qualified institutional buyers. The transaction qualified for sale treatment and removed the principal balance of the loans backing the securitization trust from our balance sheet on the settlement date. We continue to service the loans in the trust. In the second quarter of 2015, we recorded a pre-tax gain of $77 million on the sale, net of closing adjustments and transaction costs, a 10.4 percent premium.
