Debt [Abstract]
Subsequent Events Date	Mar. 17, 2020
Subsequent Event Description	On March 17, 2020, the Company, the administrative agent, and certain other parties entered into an amendment (the “Amendment”) to the New Credit Facility. The New Credit Facility requires the Company to deliver to the administrative agent and each lender the audited consolidated financial statements of the Company at the end of each fiscal year. Without having obtained the Amendment, failing to observe this financial statements covenant by March 17, 2020 with respect to the Company’s financial statements for 2019 would have been an event of default under the New Credit Facility, thereby entitling the administrative agent and the lenders to accelerate the payment of the unpaid principal amount of all outstanding loans and all interest accrued and unpaid thereon, among other remedies. The Amendment extends the delivery dates for the foregoing financial statements to April 16, 2020.
