Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Jul. 31, 2019
Accounting Policies [Abstract] |
Principles of Consolidation | Principles of Consolidation-- The accompanying Consolidated Financial Statements include the accounts of the Company and its consolidated subsidiaries for which the Company has a controlling financial interest. Investments in which the Company does not have a controlling financial interest are accounted for under the equity method. All significant intercompany transactions have been eliminated in consolidation.
Cash and Cash Equivalents | Cash and Cash Equivalents-- The Company considers all highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents.
Accounts Receivable | Accounts receivable-- The Company records trade accounts receivable in the normal course of business related to the sale of products or services. The allowance for doubtful accounts is based on a specific reserve analysis and on a percentage of accounts receivable and takes into consideration such factors as historical write-offs, the economic climate and other factors that could affect collectability. Write-offs are evaluated on a case by case basis.
Inventories | Inventories-- The Company’s inventories consist primarily of purchased retail goods, food and beverage items and spare parts. Inventories are stated at the lower of cost or net realizable value, determined using primarily an average weighted cost method. The Company records a reserve for estimated shrinkage and obsolete or unusable inventory.
Property, Plant and Equipment | Property, Plant and Equipment-- Property, plant and equipment is carried at cost net of accumulated depreciation. Repairs and maintenance are expensed as incurred. Expenditures that improve the functionality of the related asset or extend the useful life are capitalized. When property, plant and equipment is retired or otherwise disposed of, the related gain or loss is included in income from operations. Leasehold improvements are amortized on the straight-line method over the shorter of the remaining lease term or estimated useful life of the asset. Depreciation is calculated on the straight-line method, including property, plant and equipment under capital leases, generally based on the following useful lives:
| Estimated Life in Years
Land improvements | 10-35
Buildings and building improvements | 7-30
Machinery and equipment | 2-30
Furniture and fixtures | 3-10
Software | 3
Vehicles | 3-10
Real Estate Held for Sale and Investment | Real Estate Held for Sale and Investment-- The Company capitalizes as real estate held for sale and investment the original land acquisition cost, direct construction and development costs, property taxes, interest recorded on costs related to real estate under development and other related costs. Sales and marketing expenses are charged against income in the period incurred. Additionally, sales commission expenses are charged against income in the period that the related revenue from real estate sales is recorded.
Deferred Financing Costs | Deferred Financing Costs-- Certain costs incurred with the issuance of debt and debt securities are capitalized and included as a reduction in the net carrying value of long-term debt, net of accumulated amortization, with the exception of costs incurred related to line-of-credit arrangements, which are included in deferred charges and other assets, net of accumulated amortization. Amortization is charged to interest expense over the respective term of the applicable debt issues. When debt is extinguished prior to its maturity date, the amortization of the remaining unamortized deferred financing costs, or pro-rata portion thereof, is charged to loss on extinguishment of debt.
Goodwill and Intangible Assets | Goodwill and Intangible Assets-- The Company has classified as goodwill the cost in excess of estimated fair value of the net assets of businesses acquired in purchase transactions. The Company’s major intangible asset classes are trademarks, water rights, customer lists, property management contracts, Forest Service permits and excess reorganization value. Goodwill and various indefinite-lived intangible assets, including excess reorganization value, certain trademarks, water rights and certain property management contracts, are not amortized but are subject to at least annual impairment testing. The Company tests annually (or more often, if necessary) for impairment as of May 1. Amortizable intangible assets are amortized over the shorter of their contractual terms or estimated useful lives. The testing for impairment consists of a comparison of the estimated fair value of the assets with their net carrying values. If the net carrying amount of the assets exceed its estimated fair value, an impairment will be recognized for indefinite-lived intangibles, including goodwill, in an amount equal to that excess. If the net carrying amount of the assets does not exceed the estimated fair value, no impairment loss is recognized. For the testing of goodwill and other indefinite-lived intangible assets for impairment, the Company performs a qualitative analysis to determine whether it is more likely than not that the fair value of a reporting unit or indefinite-lived intangible asset exceeds the carrying amount. If it is determined, based on qualitative factors, that the fair value of the reporting unit or indefinite-lived intangible asset may be more likely than not less than carrying amount, or if significant changes to macro-economic factors related to the reporting unit or intangible asset have occurred that could materially impact fair value, a quantitative impairment test would be required, in which the Company would determine the estimated fair value of its reporting units using discounted cash flow analyses and determine the estimated fair value of its indefinite-lived intangible assets using an income approach. The Company determined that there was no impairment to goodwill and no material impairment to definite or indefinite-lived intangible assets for the years ended July 31, 2019, 2018 and 2017
Long-lived Assets | Long-lived Assets-- The Company evaluates potential impairment of long-lived assets and long-lived assets to be disposed of whenever events or changes in circumstances indicate that the net carrying amount of an asset may not be fully recoverable. If the sum of the expected cash flows, on an undiscounted basis, is less than the net carrying amount of the asset, an impairment loss is recognized in the amount by which the net carrying amount of the asset exceeds its estimated fair value. The Company does not believe any events or changes in circumstances indicating an impairment of the net carrying amount of a long-lived asset occurred during the years ended July 31, 2019, 2018 and 2017.
Revenue Recognition | Revenue Recognition The following provides information about the Company’s composition of revenue recognized from contracts with customers and other revenues, the performance obligations under those contracts, and the significant judgments made in accounting for those contracts:
• | Mountain revenue is derived from a wide variety of sources, including, among other things: lift revenue, which includes sales of lift tickets and pass products; ski school revenue, which includes the revenue derived from ski school operations; dining revenue, which includes both casual and fine dining on-mountain operations; retail sales and equipment rentals; and other on-mountain revenue, which includes private ski club revenue (which includes both club dues and amortization of initiation fees), marketing and internet advertising revenue, municipal services and lodging and transportation operations at the Company’s Australian resorts. Revenue is recognized over time as performance obligations are satisfied as control of the good or service (e.g. access to ski areas, provision of ski school services, etc.) is transferred to the customer, except for the Company’s retail sales and dining operations revenues which are recognized at a point in time when performance obligations are satisfied by transferring control of the underlying goods to the customer. The Company records deferred revenue primarily related to the sale of pass products. Deferred revenue is recognized throughout the ski season as the Company’s performance obligations are satisfied as control of the service (e.g. access to ski areas throughout the ski season) is transferred to the customer. Transfer of control is based on an estimated number of pass product holder visits relative to total expected visits. Total expected visits are estimated based on historical data, and the Company believes this estimate provides a faithful depiction of its customers’ pass product usage. When sufficient historical data to determine usage patterns is not available, such as in the case of new product offerings, deferred revenue is recognized on a straight-line basis throughout the ski season until sufficient historical usage patterns are available. The Company also includes other sources of revenue, mostly related to commercial leasing, and employee housing leasing arrangements within other mountain revenue.
• | Lodging revenue is derived from a wide variety of sources, including, among other things: revenue from owned hotel rooms and managed hotel rooms; revenue from hotel dining operations; transportation revenue which relates to the Company’s Colorado resort ground transportation operations; and other lodging revenue which includes property management services, managed properties other costs reimbursements, private golf club revenue (which includes both club dues and amortization of initiation fees), and golf course fees. Lodging revenue also includes managed hotel property payroll cost reimbursements related to payroll costs at managed properties where the Company is the employer, which are reimbursed by the owner with no added margin. Therefore, these revenues and corresponding expenses have no net effect on the Company’s operating income or net income. Other than revenue from dining operations, lodging revenue is mostly recognized over time as performance obligations are satisfied as control of the service (e.g. nightly hotel room access) is transferred to the customer.
• | Real estate revenue primarily relates to the sale of development land parcels. Real estate revenue is generally recognized at a point in time when performance obligations have been satisfied, which is usually upon closing of the sales transaction and in an amount that reflects the consideration to which the Company expects to be entitled.
For certain contracts that have an original term length of one year or less, the Company uses the practical expedient applicable to such contracts and does not consider the time value of money. For contracts with an expected term in excess of one year, the Company has considered the provisions of Topic 606 in determining whether contracts contain a financing component. The Company presents revenues in the accompanying consolidated statements of operations, net of taxes, when collected from its customers that are remitted or payable to government taxing authorities, except when products are inclusive of taxes where applicable.
Real Estate Cost of Sales | Real Estate Cost of Sales-- Costs of real estate transactions include direct project costs, common cost allocations (primarily determined on relative sales value) and sales commission expense. The Company utilizes the relative sales value method to determine cost of sales for condominium units sold within a project when specific identification of costs cannot be reasonably determined.
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Currency Translation -- The functional currency of the Company’s entities operating outside of the United States is the principal currency of the economic environment in which the entity primarily generates and expends cash, which is generally the local currency. The assets and liabilities of these foreign operations are translated at the exchange rate in effect as of the balance sheet dates. Income and expense items are translated using the weighted average exchange rate for the period. Translation adjustments from currency exchange, including intercompany transactions of a long-term nature, are recorded in accumulated other comprehensive (loss) income as a separate component of stockholders’ equity. Intercompany transactions that are not of a long-term nature are reported as gains and losses within “segment operating expense” and for intercompany loans within “foreign currency (loss) gain on intercompany loans” on the Company’s Consolidated Statements of Operations.
Reserve Estimates | Reserve Estimates-- The Company uses estimates to record reserves for certain liabilities, including medical claims, workers’ compensation claims, third-party loss contingencies and property taxes, among other items. The Company estimates the probable costs related to these liabilities that will be incurred and records that amount as a liability in its consolidated financial statements. Additionally, the Company records, as applicable, receivables related to insurance recoveries for loss contingencies if deemed probable of recovery. These estimates are reviewed and adjusted as the facts and circumstances change. The Company records legal costs related to defending claims as incurred.
Advertising Costs | Advertising Costs-- Advertising costs are expensed at the time such advertising commences. Advertising expense for the years ended July 31, 2019, 2018 and 2017 was $44.6 million, $39.8 million and $40.0 million, respectively, and was recorded within Mountain and Lodging operating expenses on the Company’s Consolidated Statement of Operations.
Income Taxes | Income Taxes-- Income tax expense includes U.S. tax (federal and state) and foreign income taxes. The Company’s provision for income taxes is based on pre-tax income, changes in deferred tax assets and liabilities and changes in estimates with regard to uncertain tax positions. Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax bases of assets and liabilities and amounts reported in the accompanying Consolidated Balance Sheets and for operating loss and tax credit carryforwards. The change in deferred tax assets and liabilities for the period measures the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws on deferred tax assets and liabilities are reflected as adjustments to the tax provision or benefit in the period of enactment. The Company’s deferred tax assets have been reduced by a valuation allowance to the extent it is deemed to be more likely than not that some or all of the deferred tax assets will not be realized. The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is “more-likely-than-not” to be sustained, on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the largest tax benefit that is cumulatively greater than 50% likely of being realized upon ultimate settlement. Interest and penalties accrued in connection with uncertain tax positions are recognized as a component of income tax expense (see Note 10, Income Taxes, for more information).
Fair Value of Financial Instruments | Fair Value of Financial Instruments-- The recorded amounts for cash and cash equivalents, receivables, other current assets and accounts payable and accrued liabilities approximate fair value due to their short-term nature. The fair value of amounts outstanding under the Company’s credit agreements and the Employee Housing Bonds (as defined in Note 5, Long-Term Debt) approximate book value due to the variable nature of the interest rate, which is a market rate, associated with the debt.
Stock-Based Compensation | Stock-Based Compensation-- Stock-based compensation expense is measured at the grant date based upon the estimated fair value of the award and is recognized as expense over the applicable vesting period of the award generally using the straight-line method (see Note 16, Stock Compensation Plan for more information), less the amount of forfeited awards which are recorded as they occur. The following table shows total net stock-based compensation expense for the years ended July 31, 2019, 2018 and 2017 included in the Consolidated Statements of Operations (in thousands):
| Year Ended July 31,
| 2019 | 2018 | 2017
Mountain stock-based compensation expense | $ | 16,474 |  | $ | 15,716 |  | $ | 14,969 |
Lodging stock-based compensation expense | 3,219 |  | 3,215 |  | 3,215 |
Real Estate stock-based compensation expense | 163 |  | 109 |  | 131 |
Pre-tax stock-based compensation expense | 19,856 |  | 19,040 |  | 18,315 |
Less: benefit from income taxes | 4,589 |  | 5,406 |  | 6,290 |
Net stock-based compensation expense | $ | 15,267 |  | $ | 13,634 |  | $ | 12,025 |
Concentration of Credit Risk | Concentration of Credit Risk-- The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and restricted cash. The Company places its cash and temporary cash investments in high-quality credit institutions. The Company does not enter into financial instruments for hedging, trading or speculative purposes. Concentration of credit risk with respect to accounts and notes receivables is limited due to the wide variety of customers and markets in which the Company transacts business, as well as their dispersion across many geographical areas. The Company performs ongoing credit evaluations of its customers and generally does not require collateral, but does require advance deposits on certain transactions.
Use of Estimates | Use of Estimates-- The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the balance sheet date and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
New Accounting Standards | Recently Issued Accounting Standards Adopted Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in Topic 605. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Subsequent to the issuance of ASU 2014-09, the FASB issued several amendments, which did not change the core principle of the guidance and were intended to clarify and improve understanding of certain topics included within the revenue standard. On August 1, 2018, the Company adopted this standard using the modified retrospective transition method for contracts which were not completed as of August 1, 2018. In accordance with this transition method, results for reporting periods beginning after August 1, 2018 are presented under Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with the Company’s historical accounting methodology under Topic 605. On August 1, 2018, as a result of adopting this standard, the Company recorded an approximate $7.5 million reduction of retained earnings with a corresponding increase in accounts payable and accrued liabilities, which was primarily associated with the measurement of the loyalty reward programs under the new standard at an estimated fair value of underlying products or services expected to be delivered to satisfy the Company’s obligations associated with such loyalty programs. The application of this standard had an immaterial impact on total net revenue and net income attributable to Vail Resorts, Inc. for the year ended July 31, 2019. In accordance with the new revenue recognition standard disclosure requirements, the impact of adoption of Topic 606 on the Consolidated Balance Sheet as of July 31, 2019 was as follows (in thousands):
| As of July 31, 2019
Balance Sheet | Balances Without Adoption of Topic 606 | Adjustments | As Reported (Under Topic 606)
Liabilities |  |  |
Accounts payable and accrued liabilities | $ | 601,507 |  | $ | 6,350 |  | $ | 607,857 |
Stockholders’ equity |  |  |
Retained earnings | $ | 766,151 |  | $ | (6,350 | ) | $ | 759,801 |
In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” This standard provides guidance for eight targeted changes with respect to how cash receipts and cash payments are classified in the statements of cash flows, with the objective of reducing diversity in practice. The Company adopted this accounting standard on August 1, 2018, which did not have an impact on its consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, “Restricted Cash,” which requires that a statement of cash flows present the change during a period for the total of cash, cash equivalents and restricted cash. Historically, under previous guidance, changes in restricted cash have been included within operating, investing or financing activities, which were eliminated under the new standard. The Company adopted this standard as of August 1, 2018, which required retrospective application to all periods presented. As a result, cash provided by operating activities during the years ended July 31, 2018 and 2017 decreased by $3.1 million and $2.2 million, respectively, under the new guidance as compared to what was reported under the previously required guidance, and cash used in investing activities during the year ended July 31, 2017 decreased by $6.2 million with regard to restricted cash acquired in the Whistler Blackcomb acquisition. Additionally, due to the inclusion of restricted cash in the beginning and end of period balances, cash, cash equivalents and restricted cash as of July 31, 2018 and 2017 increased $6.9 million and $10.3 million, respectively, as compared to what was reported under the previously required guidance. During peak operations of the North American ski season, the Company’s restricted cash balance is primarily associated with customer reservations deposits that are required to be held in a trust pursuant to statutory requirements until such reservations are fulfilled. Standards Being Evaluated The authoritative guidance listed below is currently being evaluated for its impact to Company policies upon adoption as well as any significant implementation matters yet to be addressed. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” which supersedes “Leases (Topic 840).” The standard requires lessees to recognize the assets and liabilities arising from all leases on the balance sheet, including those classified as operating leases under previous accounting guidance, and to disclose key information about leasing arrangements. The standard also allows for an accounting policy election not to recognize on the balance sheet lease assets and liabilities for leases with a term of 12 months or less. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset on their balance sheets, while lessor accounting will remain largely unchanged. The standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within those years (the Company’s first quarter of fiscal 2020), and as originally written must be applied using a modified retrospective transition approach to leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with early adoption permitted. In July 2018, the FASB released ASU No. 2018-11, Leases (Topic 842): Targeted Improvements which included providing an additional and optional transition method. Under this method, an entity initially applies the standard at the adoption date, including the election of certain transition reliefs, and recognizes a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption. The Company will adopt ASU 2016-02 on August 1, 2019 using the modified retrospective method provided by ASU No. 2018-11. By applying ASU 2016-02 as of the adoption date, as opposed to the beginning of the earliest period presented, the presentation and disclosure of financial information for periods before August 1, 2019 will remain unchanged. The Company has elected the package of practical expedients permitted under the transition guidance which allowed the Company to not reassess: (i) whether any existing or expired contracts are or contain leases; (ii) lease classification of any expired or existing leases; or (iii) initial direct costs for any existing leases. The Company has made an accounting policy election to not record leases on the balance sheet with an initial term of 12 months or less. The Company will recognize those lease payments in the consolidated statements of operations on a straight-line basis over the lease term. While the Company is still finalizing its quantification of the impact that ASU 2016-02 will have on its financial statements and disclosures, it anticipates recognizing right-of-use lease assets in the range of $212.0 million to $232.0 million and related lease liabilities in the range of $245.0 million to $265.0 million for operating leases. The Company does not expect any changes related to its current capital leases, which will be considered finance leases under ASU 2016-02. As a result of adoption, the Company will reclassify net favorable and unfavorable lease balances, deferred rent credits and other amounts from assets and liabilities of approximately $33.0 million, which will have the impact of reducing the amount it recognizes as right-of-use lease assets and which has been factored into the range above. The Company does not expect the standard to materially affect its consolidated statements of operations, consolidated statements of cash flows or debt covenant compliance agreements as of July 31, 2019.
