Senior Secured Credit Facility
Debt Outstanding [Line Items]
Credit facility, interest rate description	Borrowings under our new senior secured credit facility bear interest, at our option, at either the alternate base rate (defined as the higher of the prime rate announced by the Administrative Agent, the federal funds effective rate plus 0.5% or one-month LIBOR plus 1%) (the “Base Rate”) or at an Adjusted LIBO Rate (as defined in the credit agreement governing the new senior secured credit facility) (the “Eurodollar Rate”), except for borrowings made in alternate currencies which may not accrue interest based upon the alternate base rate, in each case, plus an applicable interest rate margin.
Debt, prepayment terms	The new senior secured credit facility also contains a requirement that we make mandatory principal prepayments on the Term Loan A and revolving line of credit in certain circumstances, including, without limitation, with 100% of the aggregate net cash proceeds from certain asset sales, casualty events or condemnation recoveries (in each case, to the extent not otherwise used for reinvestment in our business or related business and subject to certain other exceptions). The new senior secured credit facility further provides that, subject to customary notice and minimum amount conditions, we may make voluntary prepayments without payment of premium or penalty.
