On June 20, 2018, we replaced our existing credit agreement with the Fourth Amended and Restated Credit Agreement (“2018 Credit Agreement”). Terms of the 2018 Credit Agreement consist of a five year, $450 million revolving credit facility and a $150 million expansion feature, which may consist of term loans or additional revolving commitments. The 2018 Credit Agreement has a floating interest rate that is generally LIBOR plus a tiered additional rate which varies based on our current leverage ratio. For December 31, 2019 and 2018, respectively, the interest rate is LIBOR plus 100 basis points. The 2018 Credit Agreement includes transition provisions in the instance LIBOR is no longer published or used as an industry-accepted rate.

Debt issuance costs associated with the prior credit agreement were not written off as the lenders and their relative percentage participation in the facility did not change. With respect to the 2018 Credit Agreement, deferred financing costs were $1.0 million.

The debt outstanding at December 31, 2019 and 2018 consists of the following (in thousands):
