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. |  |  |  |
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 $4.5 million to $6.5 million |  |  |  |
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 10.2%, volatility of 16.0% and future period Park City EBITDA and capital expenditures, which are unobservable inputs and thus are considered Level 3 inputs. |  |  |  |

- Definition Investment in short-term money-market instruments (such as commercial paper, banker's acceptances, repurchase agreements, government securities, certificates of deposit, and so forth) which are highly liquid (that is, readily convertible to known amounts of cash) and so near their maturity that they present an insignificant risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify as cash equivalents by definition. Original maturity means an original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Glossary Cash Equivalents -URI http://asc.fasb.org/extlink&oid=6507016 + Details
