Business Combination, Contingent Consideration Arrangements, Description	42% of the amount by which EBITDA for the resort operations, as calculated under the Lease, exceed 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 fair value of Contingent Consideration includes the resort operations of Park City, following completion of the acquisition, in the calculation of EBITDA on which participating contingent payments are made, and increases the EBITDA threshold before which participating contingent payments are made by 10% of the purchase price paid by the Company for Park City along with all future capital expenditures associated with Canyons, Park City or the combined resort. The Company estimated the fair value of the Contingent Consideration payments using an option pricing valuation model. Key assumptions included a discount rate of 11.5%, volatility of 20.0%, and credit risk of 2.5%. The model also incorporates assumptions for EBITDA and capital expenditures, which are unobservable inputs and thus are considered Level 3 inputs.
