Subsequent Events [Text Block]	17. Subsequent Events Amendment and Restatement of the Vail Holdings Credit Facility On August 15, 2018, VHI, a wholly-owned subsidiary of the Company, entered into an Amendment Agreement (the “Amendment Agreement”) to amend and restate in its entirety the Vail Holdings Credit Agreement, with VHI, as borrower, the Company and certain subsidiaries of the Company, as guarantors, Bank of America, N.A., as administrative agent (the “Agent”), and the other lenders party thereto. The Amended Vail Holdings Credit Agreement provides for (i) a revolving loan facility in an aggregate principal amount of $400.0 million and (ii) a term loan facility in an aggregate principal amount of up to $950.0 million, increased from the Vail Holdings Credit Agreement term loan facility of $684.4 million as of July 31, 2018. The Company borrowed $70.0 million on August 15, 2018, primarily to fund the Stevens Pass Acquisition (as defined below), and borrowed $195.6 million on September 27, 2018 to fund the Triple Peaks Acquisition (as defined below). Pursuant to the terms of the Amended Vail Holdings Credit Agreement, VHI has the ability to increase availability (under the revolver or in the form of term loans) to an aggregate principal amount not to exceed the greater of (i) $1.2 billion and (ii) the product of 2.75 and the trailing twelve-month Adjusted EBITDA, as defined in the Amended Vail Holdings Credit Agreement. The material terms of the Amended Vail Holdings Credit Agreement are substantially similar to those of the Vail Holdings Credit Agreement. Key modifications to the Amended Vail Holdings Credit Agreement included, among other things, the extension of the maturity on the revolving credit facility to August 2023. VHI’s obligations under the Amended Vail Holdings Credit Agreement are guaranteed by the Company and certain of its subsidiaries and are collateralized by a pledge of all the capital stock of VHI and substantially all of its subsidiaries (with certain additional exceptions for the pledge of the capital stock of foreign subsidiaries). The proceeds of the loans made under the Amended Vail Holdings Credit Agreement may be used, in addition to funding resort acquisitions, as discussed below, to fund the Company’s working capital needs, capital expenditures, acquisitions, investments and other general corporate purposes, including the issuance of letters of credit. Borrowings under the Amended Vail Holdings Credit Agreement bear interest annually at a rate of (i) LIBOR plus a margin or (ii) the Agent’s prime lending rate plus a margin. Interest rate margins may fluctuate based upon the ratio of the Company’s Net Funded Debt to Adjusted EBITDA on a trailing four-quarter basis. Acquisitions Stevens Pass Resort On August 15, 2018, the Company, through a wholly-owned subsidiary, acquired Stevens Pass in the State of Washington from Ski Resort Holdings, LLC for a total purchase price of $64.0 million, subject to certain adjustments. The Company borrowed $70.0 million on August 15, 2018 under its Amended Vail Holdings Credit Agreement term loan, as discussed above, and acquired all of the assets related to the mountain operations of the resort, including base area skier services (food and beverage, retail and rental, lift ticket offices and ski and snowboard school facilities). The initial accounting for Stevens Pass is incomplete as the Company is in the process of obtaining and reviewing additional information related to the acquisition, including an analysis of the estimated fair value of assets acquired and liabilities assumed. Okemo Mountain Resort, Crested Butte Mountain Resort, Mount Sunapee Resort On September 27, 2018, the Company, through a wholly-owned subsidiary, acquired Triple Peaks, LLC (“Triple Peaks”), the parent company of Okemo Mountain Resort in Vermont, Crested Butte Mountain Resort in Colorado, and Mount Sunapee Resort in New Hampshire, for a cash purchase price of approximately $74.0 million, after adjustments for certain agreed-upon terms (the “Triple Peaks Acquisition”). In addition, at closing, Triple Peaks paid $155.0 million to pay off the leases that all three resorts had with Ski Resort Holdings, LLC, an affiliate of Oz Real Estate, with funds provided by the Company. The Company acquired all of the assets related to the mountain operations of the resorts, including base area skier services (food and beverage, retail and rental, lift ticket offices and ski and snowboard school facilities). The Company borrowed the remaining capacity of its term load under the Amended Vail Holdings Credit Agreement, as discussed above, to fund the acquisition. The Company obtained a new Special Use Permit from the U.S. Forest Service for Crested Butte, and assumed the state land leases for Okemo and Mount Sunapee.
