$77.0 million outstanding under an unsecured revolving credit facility and $75.0 million outstanding under a term loan credit facility. The carrying value of the properties collateralizing the notes payable totaled approximately $965.6 million as of September 30, 2018.

On January 26, 2018, the Company replaced its credit facility. The new credit facility, which can be used for working capital, property acquisitions, development projects or letters of credit, totals $400.0 million, of which $325.0 million is a revolving credit facility and $75.0 million is a term loan. The revolving credit facility matures on January 26, 2022, and may be extended by the Company for one additional year, subject to satisfaction of certain conditions. The term loan matures on January 26, 2023, and may not be extended. In general, loan availability under the new credit facility is primarily determined by operating income from the Company’s existing unencumbered properties. Interest accrues at a rate of LIBOR plus a spread of 135 basis points to 195 basis points under the revolving credit facility, and 130 basis points to 190 basis points under the term loan, each as determined by certain leverage tests. As of September 30, 2018, the applicable spread for borrowings is 135 basis points under the revolving credit facility and 130 basis points under the term loan. Saul Centers and certain consolidated subsidiaries of the Operating Partnership have guaranteed the payment obligations of the Operating Partnership under the new credit facility. Letters of credit may be issued under the revolving credit facility. On September 30, 2018, based on the value of the Company’s unencumbered properties, approximately $161.1 million was available under the revolving credit facility, $77.0 million was outstanding and approximately $185,000 was committed for letters of credit.
