Short-term Borrowings

Secured Borrowing Facility

On February 21, 2018 and February 20, 2019, we amended and extended the maturity of our $750 million Secured Borrowing Facility. We hold 100 percent of the residual interest in the Secured Borrowing Facility trust. Under the amended Secured Borrowing Facility, we incur financing costs of between 0.35 percent and 0.45 percent on unused borrowing capacity and a variable-yield rate plus 0.85 percent on outstandings. The amended Secured Borrowing Facility extends the revolving period, during which we may borrow, repay and reborrow funds, until February 19, 2020. The scheduled amortization period, during which amounts outstanding under the Secured Borrowing Facility must be repaid, ends on February 19, 2021 (or earlier, if certain material adverse events occur). For additional information, see Note 23, “Subsequent Events.” At December 31, 2018 and December 31, 2017, there were no 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. Rates reflect stated interest of borrowings and related discounts and premiums.

Consolidated Funding Vehicles

We consolidate our financing entities that are VIEs as a result of our being the entities’ primary beneficiary. As a result, these financing VIEs are accounted for as secured borrowings.

Other Borrowing Sources

We maintain discretionary uncommitted Federal Funds lines of credit with various correspondent banks, which totaled $125 million at December 31, 2018. 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, 2018 and 2017.

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, 2018 and December 31, 2017, the value of our pledged collateral at the FRB totaled $3.1 billion and $2.6 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, 2018 and 2017.
