Contingent Consideration, Key Assumptions for Valuation |  |  |  | The estimated fair value of Contingent Consideration includes the resort operations of Park City Mountain Resort, 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 Mountain Resort along with all future capital expenditures associated with Park City. The Company estimated the fair value of the Contingent Consideration payments using an option pricing valuation model. Key assumptions included a discount rate of 11.0%, 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. |  |  |  |  |
