12.C Senior Financing

On November 8, 2007, a structured entity consolidated by us issued a US$1,000 variable principal floating rate certificate (the

“Certificate”) to a financial institution (the “Lender”). At the same time, Sun Life Assurance Company of Canada-U.S. Operations

Holdings, Inc. (“U.S. Holdings”), a subsidiary of SLF Inc., entered into an agreement with the Lender, pursuant to which U.S. Holdings

will bear the ultimate obligation to repay the outstanding principal amount of the Certificate and be obligated to make quarterly interest payments at three-month LIBOR plus a fixed spread. SLF Inc. has fully guaranteed the obligation of U.S. Holdings. The structured entity issued additional certificates after the initial issuance, totaling to US$515, none of which were issued during 2019 and 2018. Total collateral posted per the financing agreement was US$nil as at December 31, 2019 and 2018.

The maximum capacity of this agreement is US$2,500. The agreement expires on November 8, 2037 and the maturity date may be extended annually for additional one-year periods upon the mutual agreement of the parties, provided such date is not beyond November 8, 2067. The agreement can be cancelled or unwound at the option of U.S. Holdings in whole or in part from time to time, or in whole under certain events.

For the year ended December 31, 2019, we recorded $64 of interest expense relating to this obligation ($57 in 2018). The fair value of the obligation is $1,874 ($1,879 in 2018). The fair value is determined by discounting the expected future cash flows using a current market interest rate adjusted by SLF Inc.’s credit spread and is categorized in Level 3 of the fair value hierarchy.
