Financing Activities
Debt
Total debt outstanding was $1.7 billion at June 30, 2020 and consisted of $12 million, which bears interest at variable rates, and $1.7 billion, which bears interest at fixed rates. Additionally, of our total debt, $279 million was secured by operating centers while the remaining $1.5 billion was unsecured.
At June 30, 2020, we have a $500 million unsecured revolving credit facility, which expires in March 2024 and provides borrowing rates that float at a margin over LIBOR plus a facility fee. At June 30, 2020, the borrowing margin and facility fee, which are priced off a grid that is tied to our senior unsecured credit ratings, were 82.5 and 15 basis points, respectively. The facility also contains a competitive bid feature that allows us to request bids for up to $250 million. Additionally, an accordion feature allows us to increase the facility amount up to $850 million. As of June 30, 2020, we had $12 million outstanding, and the available balance was $486 million, net of $1.9 million in outstanding letters of credit.
At June 30, 2020, we have a $10 million unsecured short-term facility that we maintain for cash management purposes.
