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 of the resort would result in a change in the estimated fair value within the range of approximately $10.1 million to $14.0 million.
Contingent Consideration, Key Assumptions for Valuation			The Company estimated the fair value of the Contingent Consideration payments using an option pricing valuation model. The estimated fair value of Contingent Consideration includes 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 annual growth factor. Other key inputs included a discount rate of 11.1%, volatility of 17.0% and other assumptions, which together with future period Park City EBITDA are all unobservable inputs and thus are considered Level 3 inputs.
