The facility is priced based on a grid related to the Company's senior unsecured credit ratings, with pricing at closing of LIBOR plus 175 basis points. The Company also entered into interest rate swaps that effectively mitigate the Company's risk to variable interest rates and provide a fixed interest stream (when cash flows from the debt and interest rate swaps are combined) at 2.66% for 4 years. The new facility contains an “accordion” feature allowing it to be increased by up to an additional $110.0 million upon satisfaction of certain conditions. The net proceeds from this new unsecured term loan facility were primarily utilized to reduce the outstanding balance of the Company's unsecured revolving credit facility to zero at closing.
