In addition, all debt investments are variable rate investments unless otherwise noted. Index-based floating interest rates are generally subject to a contractual minimum interest rate. Variable rate loans to the Company’s portfolio companies bear interest at a rate that may be determined by reference to the London Interbank Offered Rate (“LIBOR”), the Secured Overnight Financing Rate (“SOFR”), the Euro Interbank Offered Rate (“EURIBOR”), the Bank Bill Swap Bid Rate (“BBSY”), the Stockholm Interbank Offered Rate (“STIBOR”), the Canadian Dollar Offered Rate (“CDOR”), the Sterling Overnight Index Average (“SONIA”), the Swiss Average Rate Overnight (“SARON”), the Norwegian Interbank Offered Rate (“NIBOR”), the Bank Bill Market rate (“BKBM”) or an alternate base rate (commonly based on the Federal Funds Rate or the Prime Rate), at the borrower’s option, which reset annually, semi-annually, quarterly or monthly.
