Acquisition DateFair ValueAccounts receivable, net$2,499Inventory, net1,894Other assets1,422Property, plant and equipment9,612Deferred income tax assets, net15,087Intangible assets2,470Goodwill85,446Total identifiable assets acquired$118,430Accounts payable and accrued liabilities$6,671Deferred revenue5,281Capital lease obligations2,892Unfavorable lease obligations, net43,400Total liabilities assumed$58,244Total purchase price$60,186The operations of Northstar are conducted on land and with operating assets owned by affiliates of CNL Lifestyle Properties, Inc. primarily under operating lease agreements which were assumed by the Company. Under the terms of the leases, the Company estimates that it will be required to pay above market rates in the aggregate through the remainder of the initial lease term expiring in fiscal 2027. The Company has recorded a net unfavorable lease obligation for these leases that will be amortized as an adjustment to lease expense over the remaining initial lease term.The excess of the purchase price over the aggregate fair values of assets acquired and liabilities assumed was recorded as goodwill. The goodwill recognized is attributable primarily to expected synergies, the assembled workforce of Northstar and other factors. None of the goodwill is expected to be deductible for income tax purposes. The intangible assets have a weighted-average amortization period of 4.6 years. The operating results of Northstar contributed $67.9 million of net revenue for the year ended July 31, 2011. Additionally, the Company recognized $4.1 million of acquisition related expenses in the Consolidated Statements of Operations for the year ended July 31, 2011. The operating results of Northstar are reported within the Mountain segment.The following presents the unaudited pro forma consolidated financial information of the Company as if the acquisition of Northstar was completed on August 1, 2009. The following unaudited pro forma financial information includes adjustments for (i) depreciation and interest expense for capital leases on acquired property, plant and equipment and amortization of intangible assets recorded at the date of acquisition; (ii) straight-line expense recognition of minimum future lease payments from the date of acquisition, including the amortization of the net unfavorable lease obligations; and (iii) acquisition related costs. This unaudited pro forma financial information is presented for informational purposes only and does not purport to be indicative of the results of future operations or the results that would have occurred had the acquisition taken place on August 1, 2009 (in thousands, except per share amounts). Year Ended July 31,  20112010Pro forma net revenue$1,171,459$959,453Pro forma net income attributable to Vail Resorts, Inc.$33,231$34,485Pro forma basic net income per share attributable to Vail Resorts, Inc.$0.92$0.95Pro forma diluted net income per share attributable to Vail Resorts, Inc.$0.90$0.94SkiinfoOn February 1, 2012, the Company acquired the capital stock of Skiinfo, AS, a Norwegian company which owns and operates several European websites focused on the ski and snowboarding industry, for total cash consideration of $5.7 million, net of cash assumed. The purchase price was allocated to identifiable tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. The Company has completed its preliminary purchase price allocation and has recorded $2.4 million in property plant and equipment, $2.7 million in other assets, $1.8 million in goodwill, $0.7 million in indefinite-lived intangible assets, $0.5 million in other intangible assets (with a weighted-average amortization period of 6.7 years), and $2.6 million of assumed liabilities on the date of acquisition. The operating results of Skiinfo are reported within the Mountain segment.Kirkwood Mountain ResortOn April 12, 2012, the Company acquired substantially all of the assets of Kirkwood Mountain Resort (“Kirkwood”), a mountain resort located in Lake Tahoe, California, for total cash consideration of approximately $18.2 million, net of cash assumed, subject to certain working capital adjustments as provided for in the purchase agreement. The purchase price was allocated to identifiable tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. The Company has completed its preliminary purchase price allocation and has recorded $16.1 million in property, plant and equipment, $3.0 million in other assets, $0.9 million in indefinite-lived intangible assets, $1.2 million in other intangible assets (with a weighted-average amortization period of 21.4 years), and $3.0 million of assumed liabilities on the date of acquisition. The operating results of Kirkwood are reported within the Mountain segment.The estimated fair values of assets acquired and liabilities assumed for the acquisition of Kirkwood and Skiinfo are preliminary and are based on the information that was available as of the acquisition dates to estimate the fair value of assets acquired and liabilities assumed. The Company believes that information provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed, but the Company is obtaining additional information necessary to finalize those fair values. Therefore, the preliminary measurements of fair value reflected are subject to change. The Company expects to finalize the valuations and complete the purchase price allocations as soon as practicable but no later than one year from the acquisition dates. |
