Fair Value Measurements	3 Months Ended
Fair Value Measurements	Mar. 31, 2019
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements At March 31, 2019 and December 31, 2018, the Company had $89.0 million and $119.0 million, respectively, of debt outstanding under the Credit Facility which incurs interest at a variable interest rate, and therefore, the carrying amount approximates fair value. The fair value of the debt is classified as a Level 2 measurement because interest rates charged are similar to other financial instruments with similar terms and maturities. The fair value of our Senior Notes is estimated using Level 2 inputs in the fair value hierarchy and is based on quoted prices for those or similar instruments. At March 31, 2019, the fair value and the carrying value of our Senior Notes approximated $355.0 million and $398.2 million, respectively. At December 31, 2018, the fair value and the carrying value of our Senior Notes approximated $362.0 million and $398.1 million, respectively. There were no other outstanding financial assets as of March 31, 2019 and December 31, 2018 that required measuring the amounts at fair value. We did not change our valuation techniques associated with recurring fair value measurements from prior periods, and there were no transfers between levels of the fair value hierarchy during the three months ended March 31, 2019.
