The principal amount of the Company’s outstanding debt totaled approximately $864.9 million at June 30, 2016, of which approximately $838.2 million was fixed-rate debt and approximately $26.7 million was variable rate debt, including $12.0 million outstanding on the Company's unsecured revolving credit facility.

At June 30, 2016, the Company had a $275.0 million unsecured revolving credit facility, which can be used for working capital, property acquisitions, development projects or letters of credit. The revolving credit facility matures on June 23, 2018, and may be extended by the Company for one additional year subject to the Company’s satisfaction of certain conditions. Saul Centers and certain consolidated subsidiaries of the Operating Partnership have guaranteed the payment obligations of the Operating Partnership under the revolving credit facility. Letters of credit may be issued under the revolving credit facility. On June 30, 2016, based on the value of the Company’s unencumbered properties, approximately $262.6 million was available under the line, $12.0 million was outstanding and approximately $448,000 was committed for letters of credit. The interest rate under the facility is variable and equals the sum of one-month LIBOR and a margin that is based on the Company’s leverage ratio, and which can range from 145 basis points to 200 basis points. As of June 30, 2016, the margin was 145 basis points.

At June 30, 2016, the Company had a $71.6 million construction-to-permanent loan, with $63.0 million outstanding, which is secured by and used to partially finance the construction of Park Van Ness.

The Operating Partnership is the guarantor of (a) a portion of the Metro Pike Center bank loan (approximately $7.8 million of the $14.7 million outstanding at June 30, 2016) and (b) the $71.6 million Park Van Ness construction-to-permanent loan, which guarantee will be reduced and eventually eliminated subject to the achievement of certain leasing and cash flow levels. The fixed-rate notes payable are all non-recourse.
