Borrowings | Borrowings Outstanding borrowings consist of unsecured debt and secured borrowings issued through our term ABS program and our Secured Borrowing Facility. The issuing entities for those secured borrowings are VIEs and are consolidated for accounting purposes. The following table summarizes our secured borrowings at December 31, 2021 and 2020.

Short-term Borrowings On July 30, 2021, we amended our Secured Borrowing Facility to extend the maturity of the facility. The amount that can be borrowed under the facility is $2 billion. We hold 100 percent of the residual interest in the Secured Borrowing Facility trust. Under the Secured Borrowing Facility, we incur financing costs on unused borrowing capacity and on outstanding advances. The amended Secured Borrowing Facility extended the revolving period, during which we may borrow, repay, and reborrow funds, until May 17, 2022. The scheduled amortization period, during which amounts outstanding under the Secured Borrowing Facility must be repaid, ends on May 17, 2023 (or earlier, if certain material adverse events occur). At December 31, 2021, and December 31, 2020, there were no secured borrowings outstanding under the Secured Borrowing Facility. Short-term borrowings have a remaining term to maturity of one year or less. The following table summarizes the outstanding short-term borrowings, the weighted average interest rates at the end of the period, and the related average balance and weighted average interest rates during the period. The Secured Borrowing Facility’s contractual maturity is two years from the date of inception or renewal (one-year revolving period plus a one-year amortization period); however, we classify advances under our Secured Borrowing Facility as short-term borrowings because it is our intention to repay those advances within one year. The 5.125 percent unsecured Senior Notes due April 5, 2022, which we redeemed in the fourth quarter of 2021, were classified as short-term borrowings in April of 2021, and are included in the table below.

Long-term Borrowings Unsecured Debt On November 15, 2021, we redeemed our $200 million, 5.125 percent Senior Notes due April 5, 2022. The Senior Notes were redeemed at 101.39 percent of their principal amount, plus the accrued and unpaid interest thereon through the redemption date. As a result of the redemption, we recognized a $3 million loss on the transaction. On October 29, 2020, we issued at par an unsecured debt offering of $500 million of 4.20 percent Senior Notes due October 29, 2025. At December 31, 2021, the outstanding balance was $495 million.

(2) At December 31, 2021, $1.11 billion of our Private Education Loans, including $1.05 billion of principal and $62 million in capitalized interest, were encumbered related to the 2020 transactions.

(1) Other assets primarily represent accrued interest receivable. Unconsolidated VIEs Private Education Loan Securitizations Unconsolidated VIEs include variable interests that we hold in certain securitization trusts created by the sale of our Private Education Loans to unaffiliated third-parties in the first quarter of 2020 and the first six months of 2021. We remained the servicer of these loans pursuant to applicable servicing agreements executed in connection with the sales, and we are also the administrator of these trusts. Additionally, we own five percent of the securities issued by the trusts in order to meet risk retention requirements. We were not required to consolidate these entities because while as servicer we may have a significant impact on economic performance, the risk of absorbing losses that could be significant is low. 2021-A Transaction On February 9, 2021, we closed an SMB Private Education Loan Trust 2021-A term ABS transaction (the “2021-A Transaction”), in which the unaffiliated third-party sold to the trust approximately $2.5 billion of Private Education Loans that the third-party seller previously purchased from us on January 8, 2021. In the 2021-A Transaction, we were the sponsor, servicer and administrator, and the seller of an additional $130 million of Private Education Loans into the trust. The sale of such additional loans qualified for sale treatment and removed these loans from our balance sheet on the settlement date of the 2021-A Transaction and we recorded an $18 million gain on sale associated with this transaction. In connection with the 2021-A Transaction settlement, we retained a five percent vertical risk retention interest (i.e., five percent of each class issued in the securitization). We classified those vertical risk retention interests related to the 2021-A Transaction as available-for-sale investments, except for the interest in the residual class, which we classified as a trading investment recorded at fair value with changes recorded through earnings. 2021-C Transaction On May 27, 2021, we closed an SMB Private Education Loan Trust 2021-C term ABS transaction (the “2021-C Transaction”), in which the unaffiliated third-party sold to the trust approximately $505 million of Private Education Loans that the third-party seller previously purchased from us on January 8, 2021. In the 2021-C Transaction, we were the sponsor, servicer and administrator, and the seller of an additional $27 million of Private Education Loans into the trust. The sale of such additional loans qualified for sale treatment and removed these loans from our balance sheet on the settlement date of the 2021-C Transaction and we recorded an $4 million gain on sale associated with this transaction. In connection with the 2021-C Transaction settlement, we retained a five percent vertical risk retention interest (i.e., five percent of each class issued in the securitization). We classified those vertical risk retention interests related to the 2021-C Transaction as available-for-sale investments, except for the interest in the residual class, which we classified as a trading investment recorded at fair value with changes recorded through earnings. The table below provides a summary of our exposure related to our unconsolidated VIEs.

(1) Vertical risk retention interest classified as available-for-sale investment. (2) Vertical risk retention interest classified as trading investment. Other Borrowing Sources We maintain discretionary uncommitted Federal Funds lines of credit with various correspondent banks, which totaled $125 million at December 31, 2021. The interest rate we are charged on these lines of credit is priced at Fed Funds plus a spread at the time of borrowing, and is payable daily. We did not utilize these lines of credit in the years ended December 31, 2021 and 2020. We established an account at the FRB to meet eligibility requirements for access to the Primary Credit borrowing facility at the FRB’s Discount Window (the “Window”). The Primary Credit borrowing facility is a lending program available to depository institutions that are in generally sound financial condition. All borrowings at the Window must be fully collateralized. We can pledge asset-backed and mortgage-backed securities, as well as FFELP Loans and Private Education Loans, to the FRB as collateral for borrowings at the Window. Generally, collateral value is assigned based on the estimated fair value of the pledged assets. At December 31, 2021 and December 31, 2020, the value of our pledged collateral at the FRB totaled $3.3 billion and $3.8 billion, respectively. The interest rate charged to us is the discount rate set by the FRB. We did not utilize this facility in the years ended December 31, 2021 and 2020.
