Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS The Company’s primary objective in holding derivatives is to reduce the volatility of earnings and cash flows associated with changes in interest rates. The Company measures its derivative financial instruments at fair value. Australia - Ravenhall The Company’s Australian subsidiary has entered into interest rate swap agreements to fix the interest rate on its variable rate non-recourse debt related to a correctional facility project in Ravenhall, a locality near Melbourne, Australia to 4.2% during the project's operating phase. The swaps' notional amounts coincide with outstanding draws under the project. At March 31, 2019, the swaps had a notional amount of approximately AUD 448 million, or $318.1 million, based on exchange rates at March 31, 2019. The Company has determined that the swaps have payment, expiration dates, and provisions that coincide with the terms of the non-recourse debt and are therefore considered to be effective cash flow hedges. Accordingly, the Company records the change in the fair value of the interest rate swaps in accumulated other comprehensive income, net of applicable income taxes. Total unrealized gain recorded in other comprehensive income, net of tax, related to this cash flow hedge was $1.2 million during the three months ended March 31, 2019. The total fair value of the swap liability as of March 31, 2019 was $5.4 million and is recorded as a component of Other Non-Current liabilities within the accompanying consolidated balance sheet. There was no material ineffectiveness for the periods presented. If the Company refinances the debt before its maturity date, this would result in the reclassification into earnings or losses amounts associated with these swaps currently reported in accumulated other comprehensive income (loss). The Company intends to refinance the construction facility prior to September 2019. The transaction is expected to close in the second quarter of 2019 and, as such, the amounts associated with the swaps will be reclassified to earnings or losses at that time.
