Subsequent Events [Abstract]
Subsequent Event	Subsequent Event2022 Loan SalesOn April 27, 2022, we sold approximately $2.0 billion of our Private Education Loans, including approximately $1.9 billion in principal and approximately $130 million in capitalized interest to an unaffiliated third party. The gain on sale of loans sold expressed as a percentage was in the low double-digits and will be recognized in the second-quarter 2022 consolidated statements of income. The transaction qualified for sale treatment and removed the balance of the loans from our balance sheet on the settlement date. We will continue to service these loans pursuant to the terms of the applicable transaction documents.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
