Business Combination, Contingent Consideration Arrangements, Description	42% of the amount by which EBITDA for the Park City resort operations, as calculated under the Lease, exceeds approximately $35 million, as established at the transaction date, with such threshold amount subsequently increased annually by an inflation linked index and a 10% adjustment for any capital improvements or investments made under the Lease by the Company.
Contingent Consideration, Key Assumptions for Valuation	The estimated fair value of Contingent Consideration includes the future period resort operations of Park City in the calculation of EBITDA on which participating contingent payments are made, which is determined on the basis of estimated subsequent year performance, escalated by an assumed growth factor. The Company estimated the fair value of the Contingent Consideration payments using an option pricing valuation model. Key assumptions included a discount rate of 11.3%, volatility of 17.5% and future period Park City EBITDA and capital expenditures, which are unobservable inputs and thus are considered Level 3 inputs.
Sensitivity Analysis of Fair Value, Transferor's Interests in Transferred Financial Assets, Impact of Adverse Change in Other Assumption, Description	The Company prepared a sensitivity analysis to evaluate the effect that changes on certain key assumptions would have on the estimated fair value of the Contingent Consideration. A change in the discount rate of 100 basis points or a 5% change in estimated subsequent year performance would result in a change in the estimated fair value within the range of approximately $4.0 million to $5.3 million.
