Formation and Business	'
	1	Formation and Business
	Formation of the Company
	Intrawest Resorts Holdings, Inc. is a Delaware corporation that was formed on August 30, 2013, and had not, prior to the completion of the restructuring transactions in which it acquired substantially all of the assets, liabilities and operations of Intrawest Cayman L.P. (the "Partnership"), which is described below under “Restructuring”, conducted any activities other than those incident to its formation for the preparation of its initial public offering.
	The Partnership was formed on February 22, 2007 as a holding company that operated through various subsidiaries primarily engaged in the operation of mountain resorts, adventure, and real estate businesses, principally throughout North America.
	Unless the context suggests otherwise, references in the consolidated financial statements to the “Company”, “our”, “us”, or “we” refer to the Partnership and its consolidated subsidiaries prior to the consummation of the restructuring transactions described below under “Restructuring” and to Intrawest Resorts Holdings, Inc. and its consolidated subsidiaries after the consummation of the restructuring transactions described below under “Restructuring”.
	Business Operations
	The Company conducts business through three reportable segments: Mountain, Adventure and Real Estate. The Mountain segment includes the Company's mountain resorts and lodging operations at Steamboat Ski & Resort (“Steamboat”) and Winter Park Resort (“Winter Park”) in Colorado, Stratton Mountain Resort (“Stratton”) in Vermont, Snowshoe Mountain Resort (“Snowshoe”) in West Virginia, Mont Tremblant Resort (“Tremblant”) in Quebec, and a 50.0% interest in Blue Mountain Ski Resort (“Blue Mountain”) in Ontario. The Mountain segment derives revenue mainly from sales of lift pass products, lodging management, ski school services, retail and rental merchandise, food and beverage, and other ancillary services.
	The Adventure segment includes Canadian Mountain Holidays (“CMH”), which provides heli-skiing, mountaineering and hiking at eleven lodges in British Columbia, Canada. In support of CMH’s operations, the Company owns a fleet of Bell helicopters that are also used in the off-season for fire suppression in the United States and Canada and other commercial uses. The Company's subsidiary, Alpine Aerotech L.P., provides helicopter maintenance, repair and overhaul services to the Company’s fleet of helicopters as well as to aircraft owned by unaffiliated third parties.
	The Real Estate segment is comprised of and derives revenue from Intrawest Resort Club Group (“IRCG”), a vacation club business, Intrawest Hospitality Management (“IHM”), which manages condominium hotel properties in Maui, Hawaii and in Mammoth Lakes, California, and Playground, a residential real estate sales and marketing business. The Real Estate segment is also comprised of ongoing real estate development activities, and includes costs associated with these activities, including planning activities and land carrying costs.
	Restructuring
	On December 9, 2013, the Company was party to a series of transactions in which the Partnership caused its indirect subsidiaries to contribute 100% of their equity interest in both Intrawest U.S. Holdings Inc., a Delaware corporation (“Intrawest U.S.”), and Intrawest ULC, an unlimited liability company organized under the laws of the Province of Alberta (“Intrawest Canada”), to an indirect subsidiary of the Company. Concurrently, $1.1 billion of notes payable to affiliates, including $0.7 billion of accrued and unpaid interest thereon, were exchanged for 42,999,900 shares of the Company's common stock (or 41,881,903 shares after giving effect to the 0.974-for-1 reverse stock split) and subsequently canceled. The Company's subsidiaries were released from all obligations, including guarantor obligations, in respect of an additional $355.6 million of notes payable to affiliates (the "Third Lien Loan"), including $145.6 million of accrued and unpaid interest thereon. These transactions are collectively referred to as the “Restructuring.” The consolidated statements of operations include interest expense related to the Third Lien Loan of $24.4 million and $49.2 million for the years ended June 30, 2014 and 2013, respectively.
	The Restructuring was accounted for as a transaction among entities under common control as Intrawest Resorts Holdings, Inc. and the Partnership were, since August 30, 2013, and continue to be, under the common control of entities managed or controlled by Fortress Investment Group, LLC, (collectively “Fortress”). Intrawest Resorts Holdings, Inc. had no operations prior to the Restructuring. After the Restructuring and prior to the completion of the Company's initial public offering in February 2014, Fortress indirectly owned 100% of the voting and economic equity interests of the Company. The Company is the parent holding company of the businesses conducted by Intrawest U.S. and Intrawest Canada and their respective subsidiaries. Due to the entities being under common control, the assets, liabilities and equity contributed to the Company were recorded at their historical carrying values on the consolidated balance sheet. The consolidated statements of operations include the historical results of the Partnership combined with the results of the Company since the Restructuring. The consolidated statements of equity include $2.8 billion of accumulated net losses attributable to the partners, converted to and reflected as an accumulated retained deficit of the Company, and the historical contributed capital from partners of $1.4 billion, combined with the debt to equity conversion from the Restructuring, converted to and reflected as additional paid-in capital (“APIC”). The consolidated statements of cash flows reflect the activity of the historical Partnership balances combined with those of the Company since the Restructuring. The European operations of the Partnership were not contributed to the Company in connection with the Restructuring. Upon the Restructuring, the consolidated balance sheet reflects the removal of approximately $4.1 million in total assets. In addition, the consolidated balance sheet reflects an additional $1.5 billion of APIC related to the conversion of the $1.1 billion of affiliate debt and the removal of the principal balance and accrued and unpaid interest of the Third Lien Loan.
	The Company’s income tax net operating loss carryforwards were reduced due to the Restructuring. As of June 30, 2013, the Company had net operating loss carryforwards of approximately $4.0 billion, which included $2.1 billion pertaining to its European operations. Due to the Restructuring, the net operating loss carryforwards pertaining to the European operations are no longer part of the Company’s net operating loss carryforward balance. Additionally, the Restructuring resulted in cancellation of indebtedness income in the United States and Canada. In accordance with the applicable tax rules in each jurisdiction, the Company’s net operating loss carryforwards have been further reduced by approximately $0.5 billion. The Company believes uncertainty exists with respect to the future realization of the remaining net operating loss carryforwards and continues to provide a full valuation allowance. See Note 14, "Income Taxes".
	2013 Refinancing
	In conjunction with the Restructuring on December 9, 2013, one of the Company’s subsidiaries, as borrower, entered into a credit agreement (the “Credit Agreement”) with a syndicate of lenders, Goldman Sachs Bank USA, as issuing bank, and Goldman Sachs Lending Partners LLC, as administrative agent, providing for a $540.0 million term loan facility (the “Term Loan"), a $25.0 million senior secured first-lien revolving loan facility (the “Revolver”), and a $55.0 million senior secured first-lien letters of credit facility (the “LC Facility”, together with the Term Loan and Revolver, collectively referred to herein as the “FY14 Loans”). The Company has the ability to increase the size of the Term Loan under certain circumstances in an aggregate amount of up to $40.0 million after giving effect to the Blue Acquisition described in Note 20, "Subsequent Events", plus an additional amount such that, after giving effect to such additional amount, it does not exceed the total secured debt leverage ratio as required by the Credit Agreement.
	The proceeds from the Term Loan, together with cash on hand and $48.3 million contributed to the Company by Fortress, were used to refinance and extinguish the existing debt under the First Lien Credit Agreement dated December 4, 2012 (the “FY13 First Lien Loans”) and the Second Lien Credit Agreement, also dated December 4, 2012 (the “FY13 Second Lien Loans”, together with the FY13 First Lien Loans, collectively referred to herein as the “FY13 Lien Loans”). The refinancing has been accounted for as an extinguishment of debt resulting in a pre-tax loss of $35.5 million during the year ended June 30, 2014. For a description of the Credit Agreement see Note 10, “Long-Term Debt and Notes Payable to Affiliates”.
	Reverse Stock Split
	On January 21, 2014, the Company effected a 0.974-for-1 reverse stock split with no change in par value. This transaction was treated as a stock split for accounting purposes and all share and per share data is presented as if the reverse stock split occurred at the beginning of all years presented.
	Basic and diluted net loss per share attributable to common stockholders for the years ended June 30, 2014, 2013, and 2012 were computed using the number of shares outstanding after giving effect to the Restructuring and the 0.974-for-1 reverse stock split.
	Initial Public Offering
	On February 5, 2014, the Company completed its initial public offering (“IPO”) and sold 3,125,000 shares of its common stock at an offering price of $12.00 per share. Fortress sold an additional 14,843,750 shares of the Company’s common stock, including 2,343,750 shares sold on February 18, 2014 upon exercise of an option granted to the underwriters. The Company did not receive any proceeds from the sale of common stock by Fortress.
	The Company received net proceeds of $28.5 million, after deducting $2.4 million of underwriting discounts and commissions and $6.6 million of offering expenses payable by the Company. The Company used the proceeds in a manner consistent with that described in the IPO prospectus which included for working capital and other general corporate purposes.
	Following the completion of the IPO, Fortress beneficially owns 60.1% of the voting and economic equity interests of the Company.

	2	Significant Accounting Policies
	Basis of Presentation and Use of Estimates
	The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Certain previously reported amounts have been reclassified to conform to the current year financial statement presentation.
	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and all variable interest entities ("VIEs") for which the Company is the primary beneficiary. All significant intercompany transactions are eliminated in consolidation. Investments in which the Company does not have a controlling interest or is not the primary beneficiary, but over which the Company is able to exercise significant influence, are accounted for under the equity method. Under the equity method, the original cost of the investment is adjusted for the Company’s share of post-acquisition earnings or losses less distributions received.
	The Fortress contribution of Intrawest U.S. and Intrawest Canada to the Company is treated as a reorganization of entities under common control. As required by GAAP for common control transactions, all assets and liabilities transferred to the Company as part of the Restructuring were recorded in the financial statements at carryover basis. The European operations held by a wholly-owned subsidiary of the Partnership were not contributed to the Company in connection with the Restructuring.
	In January 2013, the Canadian helicopter business was reorganized and Alpine Helicopters Inc. (“Alpine Helicopters”) was formed in which the Company owns a 20% equity interest. Alpine Helicopters employs all the pilots that fly the helicopters in the CMH land tenures. Alpine Helicopters leases 100% of its helicopters from Intrawest Canada, a consolidated subsidiary, creating economic dependence and therefore giving Intrawest Canada a variable interest in Alpine Helicopters. Alpine Helicopters is a VIE for which the Company is the primary beneficiary and is consolidated in these financial statements. The remaining 80% equity interest is held by the employees of Alpine Helicopters and is reflected as a noncontrolling interest on the consolidated financial statements. As of June 30, 2014, Alpine Helicopters had total assets of $8.4 million and total liabilities of $6.0 million.
	Cash and Cash Equivalents
	Cash and cash equivalents are held in highly liquid investments, primarily demand deposit accounts with highly rated U.S. and Canadian financial institutions, with original terms to maturity of three months or less.
	Restricted Cash
	Restricted cash is comprised primarily of deposits to settle future claims related to self-insurance. Additionally, restricted cash includes guest lodging deposits in jurisdictions that require down payments or deposits to be retained in a trust account, and deposits to secure certain letters of credit.
	Receivables
	Trade receivables are recorded in the normal course of business related to the sale of products or services and presented net of an allowance for doubtful accounts. In the determination of the allowance, the Company considers specific accounts, accounts receivable aging reports, customer past repayment history, the economic environment, and other factors that could affect collectability. Write-offs are evaluated on a case by case basis.
	Interest income on notes receivables is recognized on an accrual basis when earned. Any deferred portion of contractual interest is recognized on methods that approximate the effective interest method over the term of the corresponding note. Interest income was $4.7 million, $6.6 million and $7.5 million for the years ended June 30, 2014, 2013, and 2012, respectively.
	Inventories
	Inventories consisting of retail goods, food and beverage products are recorded at the lower of cost or net realizable value, determined using the weighted-average cost method. The Company records an allowance for estimated shrinkage and obsolete or unusable inventory.
	Vacation points inventories are stated at the lower of cost or market value less cost to sell. Inventory costs are allocated to cost of point sales using a method that approximates the relative sales value method. The Company periodically reviews the carrying value of the inventory for impairment.
	Property, Plant and Equipment
	Property, plant and equipment is recorded at cost less accumulated depreciation less any impairment loss. Repairs and maintenance are expensed as incurred. Expenditures that improve the service capacity or extend the useful life of an asset are capitalized. When property, plant and equipment is retired or otherwise disposed of, the related gain or loss is included in operating income (loss). Depreciation is calculated using the straight-line method over the estimated useful lives of each asset category, which are as follows:
	Asset Category		Estimated Life in Years
	Buildings and building improvements			May-40
	Ski lifts and area improvements			30-May
	Automotive, helicopters and other equipment			20-Feb
	Golf course improvements			20
	Certain buildings, area improvements and equipment are located on leased or licensed land and are amortized over the lesser of the lease or license term or its estimated useful life.
	Real Estate Held for Development
	The Company has not been involved in new development activities during the years ended June 30, 2014, 2013, and 2012. Real estate held for development is recorded at the lower of cost or net realizable value. Land and infrastructure development costs include all expenditures incurred in connection with the acquisition, development and construction of real estate. These expenditures consist of all direct costs, interest on specific debt, interest on total costs financed by the Company's pooled debt and property taxes during the development period. The Company expenses costs directly related to the acquisition of new real estate properties and resort businesses. Costs incurred in connection with operating properties classified as real estate held for development, including indirect and general and administrative overhead costs, are recorded to cost of sales when incurred. Sales commission expenses are recorded in the same period that the related revenue is recorded.
	Real estate held for development is reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of a particular real estate property exceeds the estimated net realizable value. During the years ended June 30, 2014, 2013, and 2012, the Company experienced deteriorated real estate conditions which indicated real estate held for development could have carrying values higher than their net realizable value. Consequently, the Company obtained third party valuations and recorded impairment charges of $0.6 million, $1.1 million, and $8.1 million in the years ended June 30, 2014, 2013, and 2012, respectively. Impairments related to legacy and non-core operations for the years ended June 30, 2014, 2013, and 2012 were $0.6 million, $1.0 million, and $8.1 million, respectively. Impairments related to the Real Estate segment for the years ended June 30, 2014, 2013, and 2012 were zero, $0.1 million, and zero, respectively.
	Deferred Charges and Other
	Deferred charges and other is comprised primarily of deferred financing costs. Deferred financing costs consist of capitalized legal and other fees directly related to the issuance of debt securities, net of accumulated amortization. These costs are amortized by methods that approximate the effective interest method over the respective term of the applicable debt instrument and recorded to interest expense.
	Goodwill and Intangible Assets
	Goodwill represents the excess of purchase price over the fair value of net assets acquired in a business combination. Goodwill is not amortized, but is tested for impairment annually as of June 30th and at any time when events or circumstances suggest impairment may have occurred. The Company has reporting units with allocated goodwill in both the Mountain and Real Estate segments.
	The testing for impairment consists of a comparison of the fair value of the reporting unit with its carrying amount. If the carrying amount of the reporting unit, including goodwill, exceeds the fair value, an impairment will be recognized equal to the difference between the carrying value of the reporting unit goodwill and the implied fair value of the goodwill. For the testing of goodwill for impairment, the Company determines the estimated fair value of its reporting units based upon a discounted future cash flow analysis.
	The Company's major definite-lived intangible asset categories and estimated useful lives are as follows:
	Intangible Asset Category		Estimated Life in Years
	Permits and licenses			20-45
	Trademarks and trade names			20-Oct
	Customer relationships			8
	Other			20-Aug
	Long-lived Assets
	The Company evaluates potential impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment will be recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value.
	Deferred Revenue and Deposits
	Deferred revenue and deposits are comprised primarily of season pass revenue, lodging and tour deposits, deposits on real estate sales and mountain club initiation deposits. Deferred revenue relating to the sale of season passes is recognized throughout the season based on the estimated number of skier visits based on historical data. Lodging and tour deposits deferred revenue is recognized when the related service is provided. Deferred revenue relating to real estate deposits is recognized upon closing of the sale. Deferred revenue relating to mountain club initiation deposits is recognized on a straight-line basis over the estimated membership terms.
	Self-Insured Liabilities
	The Company has a policy of self-insuring when the expected losses from self-insurance are low relative to the cost of purchasing third-party insurance at various deductible levels. The self-insurance program includes workers’ compensation benefits in the United States and medical, property, automobile and general liability coverage in the United States and Canada. An accrual for self-insured liabilities is recorded based on management’s best estimate of the ultimate cost to settle claims considering historical claims experience, claims filed and the advice of actuaries and plan administrators.
	Liabilities for insurance-related assessments are not discounted and are included as part of accrued liabilities and other long-term liabilities on the consolidated balance sheets. As of June 30, 2014 and 2013, the liability balances were $7.5 million and $8.3 million, respectively.
	Revenue Recognition
	The Company earns revenue from a variety of sources. Revenue is recognized when the following criteria have been met: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the fee is fixed or determinable and the collection of funds is reasonably assured. The following describes revenue recognition for the Company's three segments:
	(i)	Mountain segment revenue is derived from a wide variety of sources, including sales of lift tickets (including season passes), ski school operations, dining operations, retail sales, equipment rentals, lodging operations and food and beverage operations. Persuasive evidence is obtained and collection of funds assured through cash transactions or credit card validation at the point of sale. Revenue is recognized as goods are delivered or services are performed. Season pass revenue, although primarily collected prior to the ski season, is recognized in our consolidated financial statements during the ski season based on the estimated average number of visits by season pass holders in each month during the ski season, which is based on historical three year average visitation by season pass holders at our resorts. Frequency product revenue is recognized as used, and unused portions are recognized based on the prior three year average usage for each frequency product.
	(ii)	Adventure segment revenue is derived from a variety of sources, including all-inclusive packages for stays and tours for heli-skiing, mountaineering and hiking at Company owned and leased resorts, as well as ancillary revenue from helicopter maintenance and repair services, leasing, and off-season fire suppression services. Revenue is recognized as goods are delivered or services are performed. For CMH adventure vacation packages, payments in advance are recognized as revenue as goods are delivered or services are performed.
	(iii)	The Real Estate segment earns revenue from IRCG, IHM and Playground. During the fiscal years presented, there were no active development projects or development revenue. IRCG generates revenue from the sale of vacation points, management of Club Intrawest properties, an unaffiliated, not-for-profit entity, management of a private exchange company, and income on the receivables portfolio. Vacation points revenue associated with membership in the vacation ownership business of IRCG is recognized when the purchaser has paid the amount due on closing, all contract documentation has been executed and all other significant conditions of sale are met. The Company follows real estate time-sharing accounting principles, which set out specific guidelines for assessing whether the buyer’s initial and continuing investments are adequate to demonstrate a commitment to pay for the property. Such a demonstration is required for the seller of a time-sharing arrangement to recognize profit by the full accrual method. Sales are recorded upon closing when profitability can be determined and collectability can be reasonably assured. Buyers can finance a portion of the sales price through nonrecourse loans. IHM generates revenue from managing rental operations at the Honua Kai Resort and Spa in Maui, Hawaii and the Westin Monache Resort in Mammoth Lakes, California. Playground earns revenue from the commissions on the sales of real estate. The Company also manages commercial real estate for owned properties and third parties.
	Commission revenue from brokerage operations for the Company owned real estate is included in Real Estate revenue and is recognized at the time an offer of sale is closed by the purchaser or all other contractual obligations have been satisfied. Commission revenue for third-party projects from real estate brokerage operations is included in Real Estate revenue and is recognized when the deals listing agreement is executed.
	Advertising Costs
	The Company expenses advertising costs at the time such advertising commences. Advertising costs are classified in operating expenses on the consolidated statements of operations and were $16.8 million, $14.4 million and $12.7 million for the years ended June 30, 2014, 2013, and 2012, respectively.
	Income Taxes
	Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between tax bases of assets and liabilities and book basis reported in the 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. To the extent that it is considered to be more likely than not that some or all of the deferred tax assets will not be realized, a valuation allowance is provided.
	The Company recognizes accrued interest related to uncertain tax positions as a component of income tax expense. Penalties, if incurred, are recorded in operating expenses in the consolidated statements of operations.
	Foreign Currency
	The consolidated financial statements are presented in United States dollars (“USD”). The Company’s Canadian subsidiaries generally have the Canadian dollar (“CAD”) as their functional currency.
	The accounts of entities where the USD is not the functional currency are translated into USD using the exchange rate in effect at the balance sheet date for asset and liability amounts and at the monthly average rate in effect for the period for amounts included in the determination of income. Cumulative unrealized gains or losses arising from the translation of the financial position of these subsidiaries into USD are included in total equity as a component of accumulated other comprehensive income (loss) ("AOCI").
	Exchange gains or losses arising from transactions that are denominated in foreign currencies into the applicable functional currency are included in the determination of income and are classified in other income (expense), net in the consolidated statement of operations.
	Share-Based Compensation
	On January 30, 2014, the Company’s Compensation Committee of the Board of Directors approved the terms of the 2014 Omnibus Incentive Plan (the “Plan”), which allows the Company to grant share-based compensation awards in a variety of forms such as options, stock appreciation rights, restricted stock, restricted stock units, stock bonuses, other stock-based awards and cash awards as part of the Company’s long-term incentive compensation plan.
Awards granted under the Plan generally vest based on a service condition as defined in each award. Unless otherwise determined or evidenced in an award agreement, in the event that (i) a change in control occurs, as defined in the Plan, and (ii) a participant’s employment or service is terminated without cause within 12 months following the change in control, then (a) any unvested or unexercisable portion of any award carrying a right to exercise shall become fully vested and exercisable, and (b) the restrictions, deferral limitations, payment conditions and forfeiture conditions applicable to any award will lapse and such unvested awards will be deemed fully vested and any performance conditions imposed with respect to such awards will be deemed to be fully achieved.
Compensation expense is measured based on the fair value of the award on the date of grant, net of estimated forfeitures, and is recognized as expense on a straight-line basis over the requisite service period.
Employee Benefit Plans
Substantially all of the Company’s employees are covered by Company-sponsored 401(k) plans in the U.S. and defined contribution plans in Canada. The Company’s contributions to these plans are based on a percentage of employee compensation. These plans are funded on a current basis.
In addition, certain current and former employees are covered by noncontributory defined benefit pension plans. These plans are funded in conformity with the funding requirements of applicable government regulations. Generally, benefits are based on age, years of service and level of compensation during the final years of employment. The Company accounts for these defined benefit plans by accruing its obligations under the employee benefit plans and the related costs as the underlying services are provided. The Company has frozen the plans and no further service benefits are being earned by plan participants in the defined plans.
The funded status of defined benefit plans is recognized entirely on the consolidated balance sheets. The amount recognized as an asset or liability for pension and other postretirement benefit plans is measured as the difference between the benefit obligation and the fair value of plan assets. Overfunded plans are aggregated and recognized as an asset while underfunded plans are aggregated and recognized as a liability. Actuarial gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net pension expense are recognized in accumulated other comprehensive income (loss) net of income tax effects. Actuarial gains and losses are comprised of changes in the amount of either the projected benefit obligation (for pension plans), the accumulated benefit obligation (for other postretirement plans) or differences between actual and expected return on plan assets and from changes in assumptions. The Company measures its pension assets and liabilities as of June 30th of each year.
Fair Value of Financial Instruments
Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. A three-tier fair value hierarchy, which is described below, prioritizes the inputs used in measuring fair value:
•	Level 1 – Quoted prices for identical instruments in active markets.
•	Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations, in which all significant inputs are observable in active markets.
•	Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
The Company has various financial instruments, including cash and cash equivalents, receivables, payables, accrued liabilities and debt obligations. Due to their short-term nature, or, in the case of note receivables, their market comparable interest rates, the instruments’ book value approximates their fair value.
The fair value of the FY14 Lien Loan was estimated using quoted prices for our instruments in markets that are not active and was considered a Level 2 measure. The fair value of the FY13 Lien Loans was estimated based on Level 3 inputs using discounted future contractual cash flows and a market interest rate based on published corporate borrowing rates for debt instruments with similar terms and average maturities, with adjustments for credit risk. The fair value of other obligations was estimated based on Level 3 inputs using discounted cash flow analyses based on assumptions that management believed were consistent with market participant assumptions.
The Company’s long-term debt obligations are not measured and carried at fair value on a recurring basis. The Company’s debt is initially recorded based upon historical cost. The fair value of debt does not represent the amounts that will ultimately be paid upon the maturities of the loans.
Derivative Financial Instruments
The Company engages in activities that expose it to market risks including the effects of changes in interest rates and exchange rates. Financial exposures are managed as an integral part of the Company’s risk management activities, which seek to reduce the potentially adverse effect that the volatility of interest rates or exchange rates may have on operating results.
As of June 30, 2014 and 2013, the Company had no significant outstanding derivative instruments. Prior to October 2008, the Company had outstanding interest rate swaps that were accounted for as cash flow hedges. The outstanding swap contracts were terminated on October 11, 2008, and the deferred loss previously recorded in AOCI is being recognized in earnings during the period that the hedge covered, which ends on March 31, 2017. Approximately $1.8 million of deferred losses related to the terminated interest rate swaps will be amortized from AOCI into interest expense in the next 12 months.
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, but these investments may be in excess of regulatory insurance limits. The Company does not enter into financial instruments for trading or speculative purposes. Concentration of credit risk with respect to trade and notes receivables is limited due to the large number of customers and small transactions associated with the Company’s consumer and retail operations and the wide variety of customers and markets in which the Company transacts business. No customer represented 10% or more of total revenue or receivables during the years ended June 30, 2014, 2013, and 2012. Where the Company provides financing, the Company performs ongoing credit evaluations of its customers and generally does not require collateral, but does require advance deposits on certain transactions.
Recent Accounting Pronouncements
In July 2012, the Financial Accounting Standards Board (“FASB”) issued ASU 2012-02, Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. This update amends ASU 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment and permits an entity first to assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with Subtopic 350-30, Intangibles - Goodwill and Other - General Intangibles Other than Goodwill. The Company adopted the provisions of the ASU effective July 1, 2013. The adoption of ASU 2012-02 did not have a material impact on the Company’s financial position, results of operations or cash flows.
In February 2013, the FASB issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The ASU does not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the ASU requires an entity to provide information about the amounts reclassified out of AOCI by component. Specifically, the ASU requires the Company to present either in a single note or parenthetically on the face of the financial statements the effect of significant amounts reclassified from each component of AOCI based on its source and the income statement line items affected by the reclassification. If a component is not required to be reclassified to net income in its entirety, the Company would instead cross- reference to the related note for additional information. The guidance included in ASU 2013-02 was effective for the Company beginning July 1, 2013 and was applied prospectively. The adoption of this authoritative guidance did not have an impact on the Company’s financial position, results of operations or cash flows.
In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360):  Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.  This update raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures for discontinued operations as well as certain other disposals that do not meet the definition of a discontinued operation.  The guidance is effective for annual periods beginning on or after December 15, 2014 with early adoption permitted only for disposals that have not been previously reported.  The Company does not anticipate that the adoption of ASU 2014-08 will have a material impact on the Company's financial position, results of operations or cash flows.
On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective July 1, 2017. Early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is currently in the process of evaluating the impact that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

	Basic earnings (loss) per share ("EPS") is calculated by dividing net income (loss) attributable to the Company by the weighted average number of shares of common stock outstanding. Diluted EPS is calculated by dividing net income (loss) attributable to the Company by the weighted average number of shares of common stock outstanding, plus potentially dilutive securities. Potentially dilutive securities include unvested restricted common stock and restricted stock units, the dilutive effect of which is calculated using the treasury stock method.
	The Restructuring was accounted for as a transaction among entities under common control. As a result, the Company is retrospectively presenting the shares outstanding for all periods presented prior to the IPO.
	Due to the Company's reported net loss for the years ended June 30, 2014, 2013, and 2012, the effect of 0.1 million anti-dilutive stock awards were not included in the calculation of EPS. The calculation of basic and diluted EPS is presented below (in thousands, except per share data).

	FY14 Loans
	As described in Note 1, “Formation and Business”, the Company entered into the Credit Agreement providing for a $540.0 million Term Loan. The Company has the ability to increase the size of the Term Loan under certain circumstances in an aggregate amount of up to $40.0 million after giving effect to the Blue Acquisition described in Note 20, "Subsequent Events", plus an additional amount such that, after giving effect to such additional amount, it does not exceed the total secured debt leverage ratio as required by the Credit Agreement. The proceeds from the Term Loan, together with cash on hand and $48.3 million contributed to the Company by Fortress, were used to refinance and extinguish the existing debt under the FY13 Lien Loans.
	The refinancing has been accounted for as an extinguishment of debt resulting in a pre-tax loss of $35.5 million during the year ended June 30, 2014, consisting of the difference between the principal value and the reacquisition price of the FY13 Lien Loans and the write-off of the related unamortized financing costs and unamortized original issue discount (“OID”). The following table provides the calculation of the net loss on debt extinguishment for the year ended June 30, 2014:
			Year Ended June 30, 2014
	FY13 First Lien Loans		$	446,625
	FY13 Second Lien Loans			125,000
	Total FY13 Lien Loans			571,625
	Total reacquisition price			(580,389	)
	Write off of unamortized discount and financing fees related to FY13 Lien Loans			(26,716	)
	Loss on debt extinguishment		$	(35,480	)
	The Term Loan has a maturity date of December 9, 2020. Borrowings under the Credit Agreement, including the Term Loan, LC Facility, and Revolver bear interest, at the Company's option, at a rate equal to either an adjusted LIBOR rate or a base rate, in each case plus the applicable margin. The applicable margin for borrowings under the Credit Agreement is 4.5% for adjusted LIBOR loans or 3.5% for base rate loans. The applicable margin for borrowings under the LC Facility and Revolver may change depending on the Company's total secured debt leverage ratio, which may not be higher than 4.5%. The Company's current applicable margin is 4.5%. The Term Loan currently bears interest based upon the LIBOR-based rate. The Credit Agreement requires quarterly principal payments in the amount of $1.4 million that commenced on March 31, 2014 and periodic interest payments that commenced as of December 31, 2013.
	The net cash proceeds from the Term Loan were reduced by an OID of 1.0%, or $5.4 million. The OID is amortized using a method which approximates the effective interest method over the term of the Term Loan. There was $5.0 million of unamortized OID remaining as of June 30, 2014.
	The Company capitalized $16.9 million of costs in connection with the FY14 Loans included in deferred charges and other on the consolidated balance sheets. These costs are amortized using a method which approximates the effective interest method over the term of the Term Loan. There was $15.4 million of unamortized costs remaining as of June 30, 2014.
	The Company’s obligations under the Credit Agreement are collateralized by guarantees of substantially all of its material U.S. subsidiaries. The guarantees are further supported by mortgages and other security interests in certain properties and assets held by U.S. subsidiaries of the Company. The collateral includes both general and specific assets.
	The Credit Agreement provides for affirmative and negative covenants that the Company believes are usual and customary for a senior secured credit agreement. The negative covenants restrict, among other things, the Company’s ability and the ability of its subsidiaries to incur indebtedness, dispose of property, or make investments or distributions. It also includes customary cross-default provisions with respect of certain other borrowings of the Company and its subsidiaries. The Credit Agreement also requires the Company to comply with a total secured debt leverage ratio to the extent that more than 30% of the Revolver is outstanding (including outstanding swingline loans and letters of credit) on the last day of each fiscal quarter. The Company was in compliance with the covenants of the Credit Agreement at June 30, 2014.
	In addition to the Term Loan, the Credit Agreement provided a $55.0 million LC Facility and a $25.0 million Revolver. The LC Facility and the Revolver each have a maturity date of December 9, 2018.
	The LC Facility includes fronting fees of 25 basis points, and a commitment fee of 37.5 basis points on the first 15% of unutilized commitments. The letters of credit issued under the FY13 Lien Loans were deemed issued under the LC Facility.  There were $47.6 million of irrevocable standby letters of credit outstanding under the LC Facility at June 30, 2014.
	The Revolver includes commitment fees of 37.5 basis points. There were no outstanding borrowings under the Revolver at June 30, 2014.
	FY13 Lien Loans
	As a result of entering into the FY14 Loans and refinancing and extinguishing the FY13 Lien Loans, the Company paid a call premium, totaling $4.4 million and $3.8 million related to the FY13 First Lien and FY13 Second Lien Loans, respectively, which is included in loss on extinguishment of debt in the consolidated statement of operations for the year ended June 30, 2014.
	Additionally, the Company wrote off $8.3 million of unamortized discount and $18.4 million of unamortized financing costs related to the FY13 First Lien and FY13 Second Lien Loans which are included in loss on extinguishment of debt in the consolidated statement of operations for the year ended June 30, 2014.
	Maturities
	Current maturities represent principal payments due in the next 12 months. As of June 30, 2014, the long-term debt aggregate maturities for the 12 month periods are as follows (in thousands):
	2015		$	6,644
	2016			6,454

	Notes Payable to Affiliates
	In connection with the Restructuring, the Third Lien Loan was amended to release the Company’s subsidiaries from their obligations in respect of the Third Lien Loan and accrued and unpaid interest thereon. The Tranche B Term Loans and Affiliate Loans, including accrued and unpaid interest thereon, were exchanged for equity interests in the Company and subsequently canceled.
	There were no notes payable to affiliates outstanding as of June 30, 2014. Notes payable to affiliates as of June 30, 2013 were $1.4 billion in the aggregate.
	Interest Expense
	The Company recorded interest expense of $173.0 million, $335.0 million, and $331.8 million in the consolidated statements of operations for the years ended June 30, 2014, 2013, and 2012, of which $3.5 million, $5.0 million, and $5.5 million was amortization of deferred financing costs.
	In October 2006, the Company entered into interest rate swap contracts to minimize the impact of changes in interest rates on its cash flows for certain of the Company’s floating bank rates and other indebtedness. The outstanding swap contracts were terminated on October 11, 2008. The fair value of the swap contracts at October 11, 2008 was a liability of $111.4 million. The remaining terminated swap liability of $3.3 million as of June 30, 2014 is recorded in AOCI and will be recognized periodically through March 31, 2017 as an adjustment to interest expense consistent with US GAAP. The portion included in interest expense in the consolidated statements of operations for the years ended June 30, 2014, 2013, and 2012 was $4.2 million, $3.9 million, and $5.6 million, respectively.

Estimates of fair value may be affected by assumptions made and, accordingly, are not necessarily indicative of the amounts the Company could realize in a current market exchange.

	As described in Note 10, “Long-Term Debt and Notes Payable to Affiliates”, the FY13 Lien Loans were refinanced and extinguished with the proceeds from the Term Loan, together with cash on hand and $48.3 million contributed to the Company by Fortress.
	Due to the debt terms received from affiliates, the Company determined that it was not practicable to estimate the fair value of the notes payable to affiliates as of June 30, 2013 because of the lack of market comparable terms and the inability to estimate the fair value without incurring excessive cost. None of the notes payable to affiliates were outstanding following the Restructuring.

	As of June 30, 2014 and 2013, net deferred tax liabilities of $86,000 and $31,000, respectively, are included within other long-term liabilities on the consolidated balance sheets. The gross deferred tax liability is noncurrent and the net deferred tax asset, after the valuation allowance, is also noncurrent. There is no current deferred tax asset due to the valuation allowance.
	Included as part of the $1.7 billion valuation allowance as of June 30, 2013 is $1.0 billion related to the European operations. As a result of the Restructuring, the valuation allowance pertaining to the European operations is no longer reflected as part of the $607.3 million valuation allowance as of June 30, 2014.
	The increase in the net deferred tax liability from fiscal 2013 to fiscal 2014 is primarily the result of certain Canadian operations. The Company has noncapital loss carryforwards for income tax purposes of approximately $1.6 billion and $4.0 billion as of June 30, 2014 and 2013, respectively, that are available to offset future taxable income and will expire in varying amounts over the next 20 years.
	The Company’s income tax net operating loss carryforwards were reduced due to the Restructuring. As of June 30, 2013, the Company had net operating losses of approximately $4.0 billion, which included $2.1 billion pertaining to the European operations. As a result of the Restructuring, the net operating loss carryforwards pertaining to the European operations are no longer part of the Company’s net operating loss carryforward balance. Additionally, the Restructuring resulted in cancellation of indebtedness income in the United States and Canada. In accordance with the applicable tax rules in each jurisdiction, cancellation of indebtedness income reduced the Company’s net operating loss carryforwards by approximately $0.5 billion. The Company’s net operating loss carryforwards pertaining to federal, state and foreign jurisdictions will primarily expire after 2024 and are as follows (in thousands):
			June 30,
			2014			2013
	United States		$	941,924		$	1,373,405
	Canada			628,690			505,177
	Europe			—			2,140,920
			$	1,570,614		$	4,019,502
	Due to the Restructuring, the Company’s $94.8 million capital loss carryforward in the United States as of June 30, 2013 was fully utilized to reduce cancellation of indebtedness income. The amount of loss carryforwards reflect the Company’s best estimate and are subject to final determination by the taxing authorities.
	The Company believes that uncertainty exists with respect to the future realization of the loss carryforwards and a full valuation allowance has been established for the net operating loss carryforwards. The Company has concluded that it is not more likely than not that the benefit of these losses will be utilized prior to their expiration date.
The Company, or one of its subsidiaries, files income tax returns in the U.S. federal jurisdiction and various states, Canada federal jurisdiction and various provinces. With few exceptions, the Company is no longer subject to federal, state and local examinations by the tax authorities in most jurisdictions for years before June 30, 2011. Various examinations are ongoing, which are not anticipated to have a material impact on the Company’s financial statements.
A reconciliation of unrecognized tax benefits is as follows (in thousands):
		2014			2013			2012
Balance as of July 1		$	19,821		$	17,167		$	22,536

Balance as of June 30		$	9,576		$	19,821		$	17,167
The remaining uncertain tax benefits balance at June 30, 2014, if recognized, would only reduce net operating losses in the United States and would have no impact on the annual effective tax rate.
Included in the unrecognized tax benefits balance as of June 30, 2014 were $2.9 million of tax positions, which the Company expects will change within 12 months due to settlement or expiration of statutes of limitation. Due to the Restructuring, uncertain tax positions of $0.3 million related to the European operations are no longer part of the Company’s uncertain tax balance as of June 30, 2014.

Commitments and Contingencies	'
	15	Commitments and Contingencies
	Letters of Credit
	The Company issued letters of credit of $47.6 million and $52.4 million at June 30, 2014 and 2013, respectively, mainly to secure its commitments under self-insurance claims and the three closed noncontributory defined benefit pension plans covering certain of its former executives. All outstanding letters of credit will expire in November 2018.
	Legal
	The Company and its subsidiaries are involved in various lawsuits arising in the ordinary course of business. In addition, the Company’s pre-2010 legacy real estate development activities, combined with the downward shift in real estate asset values that occurred in 2007 and 2008, resulted in claims being filed against the Company by owners and prospective purchasers of residences of the Company’s real estate developments. The Company was named as a defendant in lawsuits alleging construction defects at certain of the Company’s existing developments. In other lawsuits, purchasers are seeking rescission of real estate purchases and/or return of deposits paid on pre-construction purchase and sale agreements. These claims are related to alleged violations of state and federal laws that require providing purchasers with certain mandated disclosures.
	The Company believes that it has adequate insurance coverage or has accrued for loss contingencies for all material matters in which it believes a loss is probable and the amount of the loss is reasonably estimable. Although the ultimate outcome of claims cannot be ascertained, current pending and threatened claims are not expected to have a material adverse effect, individually or in the aggregate, on the Company’s financial position, results of operations or cash flows.
	Government Grants and Loans
	The federal government of Canada and the provincial government of Quebec have granted financial assistance to certain subsidiaries of the Company in the form of reimbursable loans and forgivable grants for the construction of specified tourist facilities at Tremblant. The unamortized balance of forgivable government grants received are included in other long-term liabilities on the consolidated balance sheets and recorded as a reduction in depreciation expense of the related fixed asset or a reduction in cost of sales for property under development at the time a sale is recognized.
	Reimbursable government loans and forgivable grants as of June 30, 2014 and 2013 in CAD and USD equivalent are as follows (in thousands):

	Capital lease obligations are primarily for equipment except for the lease of Winter Park ski resort. In the first fiscal quarter of 2014, the Winter Park capital lease was modified to remove a floor on a payment obligation in exchange for other concessions resulting in a $19.6 million increase to the capital lease obligation and related capital lease assets due to a change in the present value of the future minimum lease payments. The Winter Park capital lease requires annual payments, a portion of which are contingent on future annual gross revenue levels. As such, the obligation associated with the contingent portion of the payments is not readily determinable and has not been recorded.
	Amortization of assets under capital leases is included in depreciation and amortization expense in the consolidated statements of operations. The leases have remaining terms ranging from 7 years to 38 years and have a weighted average interest rate of 10%. Total interest expense related to capital leases for the years ended June 30, 2014, 2013 and 2012 was $2.8 million, $1.4 million and $1.2 million.
	Total rent expense recorded in operating expenses in the consolidated statements of operations for the years ended June 30, 2014, 2013 and 2012 was $15.1 million, $15.1 million and $17.9 million, respectively.
	Other
	The Company holds forestry licenses and land leases with respect to certain of its resort operations. These leases expire (or expired)  at various times between 2012 and 2051 and provide for annual payments of approximately 2% of defined gross revenue. Payments for forestry licenses and land leases for the years ended June 30, 2014, 2013 and 2012 were $2.8 million, $2.4 million and $2.6 million, respectively.

	Assumptions
	The discount rate used to determine the obligations of the Executive plans at the measurement date of June 30, 2014 was based on market yields on high quality corporate bonds in Canada. The hypothetical yield curve is made up of AA rated corporate bonds. The average timing of benefit payments was compared to average timing of cash flows from the long‑term bonds to assess potential timing adjustments. The resulting discount rate was 3.8% as of June 30, 2014.
	The discount rate used to determine the obligations of the Employee plans at the measurement date of June 30, 2014 was based on a hypothetical yield curve represented by a series of annualized individual discount rates from highly rated bonds. The resulting discount rate was 3.8% as of June 30, 2014.
	The expected long‑term rate of return for the Executive plans employs a building block approach based on historical markets and historical relationship between equities and fixed income investments. Current market factors are also evaluated.
	The expected long‑term rate of return for the Employee plans is based on the portfolio as a whole and not on the sum of the returns on individual asset categories. The return is based exclusively on historical returns, without adjustments.
	The weighted average assumptions used to determine the Company's benefit obligations at June 30 were as follows:
			Executive plans						Employee plans
			2014			2013			2014			2013
	Discount rate			3.8	%		4.3	%		3.8	%		4.4	%
	Expected rate of return on plan assets			2.4	%		2	%		6.1	%		6	%
	The weighted average assumptions used to determine the Company's net periodic benefit cost for the years 2014, 2013, and 2012 were as follows:

The funds are benchmarked to the MSCI EAFE index.
-11	This category of funds seeks total return, consisting of income and capital appreciation. Under normal circumstances, the funds invest at least 80% of their net assets in investment-grade bonds or fixed grade income securities, up to 25% of the funds’ total assets in asset-backed securities, and up to 20% of the funds’ total assets in U.S. dollar denominated debt securities of foreign issuers. The funds are benchmarked to the Barclays Capital U.S. Aggregate Bond index.
Transfers between levels of the fair value hierarchy are recognized at the end of the fiscal year, which generally coincides with the Company's valuation process. During the year ended June 30, 2014, there were no pension asset transfers between the levels of the fair value hierarchy. In the year ended June 30, 2013, $4.4 million of pension assets, classified as Level 2 as of June 30, 2012, were liquidated from certain investments and reinvested in pooled fund investments, which were classified as Level 2 assets as of June 30, 2013.
The Executive and Employee plans employ a total return investment approach whereby a mix of equities and fixed income investments are used to maximize the long‑term return of plan assets for a prudent level of risk. Risk tolerance is established through careful consideration of plan liabilities and plan funded status. The investment portfolio contains a diversified blend of equity and fixed income investments. Furthermore, equity investments are diversified across U.S. and non‑U.S. stocks, as well as growth, value, and small and large capitalizations. Investment risk and surplus risk (i.e., plan assets minus plan liabilities) are measured and monitored on an ongoing basis through quarterly investment portfolio reviews, annual liability measurements and periodic asset/liability studies.
The asset allocation strategy varies by plan. The following table reflects the 2014 target asset allocation, as well as the actual asset allocations, by asset category, for the Company's pension plans as of June 30, 2014 and 2013:

Segment Information [Abstract]	'
Segment Information	'
	18	Segment Information
	The Company currently manages and reports operating results through three reportable segments: Mountain, Adventure and Real Estate. The Mountain segment includes the operations of the Company’s mountain resorts and related ancillary activities. The Mountain segment earns revenue from a variety of activities including lift revenue, lodging revenue, ski school revenue, retail and rental revenue, food and beverage revenue, and other revenue. The Adventure segment comprises CMH, which earns revenue from the sale of heli-skiing, mountaineering and hiking adventure packages, and ancillary services, which earns revenue from fire suppression services and maintenance, repair and overhaul of aircraft. The Real Estate segment includes a vacation club business, management of condominium hotel properties, real estate management, including marketing and sales activities, as well as ongoing real estate development activities.
	Each of the Company’s reportable segments offers distinctly different products and services and requires different types of management focus. As such, these segments are managed separately. In deciding how to allocate resources and assess performance, the Company’s Chief Operating Decision Maker (“CODM”) regularly evaluates the performance of its reportable segments on the basis of revenue and segment Adjusted earnings before interest, taxes, depreciation and amortization (“EBITDA”). Total segment Adjusted EBITDA equals Adjusted EBITDA. The Company also evaluates segment Adjusted EBITDA as a key compensation measure. The compensation committee determines the annual variable compensation for certain members of the management team based, in part, on Adjusted EBITDA or segment Adjusted EBITDA. Segment Adjusted EBITDA assists in comparing the segment performance over various reporting periods because it removes from the operating results the impact of items that our management believes do not reflect the core operating performance.
	The reportable segment measure of Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income (loss) or other measures of financial performance or liquidity derived in accordance with GAAP. Segment Adjusted EBITDA may not be comparable to similarly titled measures of other companies because other entities may not calculate segment Adjusted EBITDA in the same manner. The Company's definition of Adjusted EBITDA is generally consistent with the definition of Consolidated EBITDA in the Credit Agreement, except that we do not adjust for recurring public company costs and foreign currency translation adjustments related to operational activities.
	The Company defines Adjusted EBITDA as net income (loss) attributable to Intrawest Resorts Holdings, Inc. before interest expense, net (excluding interest income earned from receivables related to IRCG operations), income tax benefit or expense, and depreciation and amortization, further adjusted to exclude certain items, including, but not limited to: (i) impairments of goodwill, real estate and long-lived assets; (ii) gains and losses on asset dispositions; (iii) earnings and losses from equity method investments; (iv) gains and losses from disposal of equity method investments; (v) gains and losses on extinguishment of debt; (vi) other income or expense; (vii) earnings and losses attributable to noncontrolling interest; (viii) discontinued operations, net of tax; and (ix) other items, which include revenue and expenses of legacy and other non-core operations, restructuring charges and associated severance expenses, non-cash compensation and other items. For purposes of calculating Adjusted EBITDA, the Company also adds back to net (income) loss attributable to Intrawest Resorts Holdings, Inc. the pro rata share of EBITDA related to equity method investments included within the reportable segments and removes from Adjusted EBITDA the Adjusted EBITDA attributable to noncontrolling interests for entities consolidated within the reportable segments. Asset information by segment, except for capital expenditures as shown in the table below, is not included in reports used by the CODM in monitoring of performance and, therefore, is not disclosed.
	The accounting policies of the segments are the same as those described in Note 2, "Significant Accounting Policies". Transactions among segments are accounted for as if the sales or transfers were to third parties, or, in other words, at current market prices.
	The following table presents consolidated revenue and net income (loss) reconciled to segment Adjusted EBITDA, (in thousands):

	20.    Subsequent Events
	On September 19, 2014, the Company acquired the remaining 50.0% equity interest in Blue Mountain Ski Resort in exchange for CAD $58.0 million, or approximately USD $52.9 million (the "Blue Acquisition"). The transaction was financed through $60.0 million of incremental term loan proceeds and existing cash. As Blue Mountain Ski Resort is Canada's third largest ski resort by visitation, located just over 90 miles from the Greater Toronto area, the Company expects the acquisition to result in significant incremental cash flow.
	The following unaudited pro forma consolidated results of operations have been prepared as if the acquisition of the remaining 50.0% interest in Blue Mountain occurred at the beginning of the year ended June 30, 2013. The pro forma information does not necessarily reflect the actual results of operations had the acquisition been consummated at the beginning of the fiscal period indicated nor is it indicative of future operating results. The pro forma information does not include any adjustment for (i) potential revenue enhancements, cost synergies or other operating efficiencies that could result from the acquisition or (ii) transaction or integration costs related to the acquisition.

Significant Accounting Policies [Abstract]	'
Basis of Presentation and Use of Estimates	'
	Basis of Presentation and Use of Estimates
	The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Certain previously reported amounts have been reclassified to conform to the current year financial statement presentation.
Principles of Consolidation	'
	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and all variable interest entities ("VIEs") for which the Company is the primary beneficiary. All significant intercompany transactions are eliminated in consolidation. Investments in which the Company does not have a controlling interest or is not the primary beneficiary, but over which the Company is able to exercise significant influence, are accounted for under the equity method. Under the equity method, the original cost of the investment is adjusted for the Company’s share of post-acquisition earnings or losses less distributions received.
	The Fortress contribution of Intrawest U.S. and Intrawest Canada to the Company is treated as a reorganization of entities under common control. As required by GAAP for common control transactions, all assets and liabilities transferred to the Company as part of the Restructuring were recorded in the financial statements at carryover basis. The European operations held by a wholly-owned subsidiary of the Partnership were not contributed to the Company in connection with the Restructuring.
	In January 2013, the Canadian helicopter business was reorganized and Alpine Helicopters Inc. (“Alpine Helicopters”) was formed in which the Company owns a 20% equity interest. Alpine Helicopters employs all the pilots that fly the helicopters in the CMH land tenures. Alpine Helicopters leases 100% of its helicopters from Intrawest Canada, a consolidated subsidiary, creating economic dependence and therefore giving Intrawest Canada a variable interest in Alpine Helicopters. Alpine Helicopters is a VIE for which the Company is the primary beneficiary and is consolidated in these financial statements. The remaining 80% equity interest is held by the employees of Alpine Helicopters and is reflected as a noncontrolling interest on the consolidated financial statements. As of June 30, 2014, Alpine Helicopters had total assets of $8.4 million and total liabilities of $6.0 million.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents are held in highly liquid investments, primarily demand deposit accounts with highly rated U.S. and Canadian financial institutions, with original terms to maturity of three months or less.
Restricted Cash	'
	Restricted Cash
	Restricted cash is comprised primarily of deposits to settle future claims related to self-insurance. Additionally, restricted cash includes guest lodging deposits in jurisdictions that require down payments or deposits to be retained in a trust account, and deposits to secure certain letters of credit.
Receivables	'
	Receivables
	Trade receivables are recorded in the normal course of business related to the sale of products or services and presented net of an allowance for doubtful accounts. In the determination of the allowance, the Company considers specific accounts, accounts receivable aging reports, customer past repayment history, the economic environment, and other factors that could affect collectability. Write-offs are evaluated on a case by case basis.
	Interest income on notes receivables is recognized on an accrual basis when earned. Any deferred portion of contractual interest is recognized on methods that approximate the effective interest method over the term of the corresponding note. Interest income was $4.7 million, $6.6 million and $7.5 million for the years ended June 30, 2014, 2013, and 2012, respectively.
Inventories	'
	Inventories
	Inventories consisting of retail goods, food and beverage products are recorded at the lower of cost or net realizable value, determined using the weighted-average cost method. The Company records an allowance for estimated shrinkage and obsolete or unusable inventory.
	Vacation points inventories are stated at the lower of cost or market value less cost to sell. Inventory costs are allocated to cost of point sales using a method that approximates the relative sales value method. The Company periodically reviews the carrying value of the inventory for impairment.
Property, Plant and Equipment	'
	Property, Plant and Equipment
	Property, plant and equipment is recorded at cost less accumulated depreciation less any impairment loss. Repairs and maintenance are expensed as incurred. Expenditures that improve the service capacity or extend the useful life of an asset are capitalized. When property, plant and equipment is retired or otherwise disposed of, the related gain or loss is included in operating income (loss). Depreciation is calculated using the straight-line method over the estimated useful lives of each asset category, which are as follows:
	Asset Category		Estimated Life in Years
	Buildings and building improvements			May-40
	Ski lifts and area improvements			30-May
	Automotive, helicopters and other equipment			20-Feb
	Golf course improvements			20
	Certain buildings, area improvements and equipment are located on leased or licensed land and are amortized over the lesser of the lease or license term or its estimated useful life.
Real Estate Held for Development	'
	Real Estate Held for Development
	The Company has not been involved in new development activities during the years ended June 30, 2014, 2013, and 2012. Real estate held for development is recorded at the lower of cost or net realizable value. Land and infrastructure development costs include all expenditures incurred in connection with the acquisition, development and construction of real estate. These expenditures consist of all direct costs, interest on specific debt, interest on total costs financed by the Company's pooled debt and property taxes during the development period. The Company expenses costs directly related to the acquisition of new real estate properties and resort businesses. Costs incurred in connection with operating properties classified as real estate held for development, including indirect and general and administrative overhead costs, are recorded to cost of sales when incurred. Sales commission expenses are recorded in the same period that the related revenue is recorded.
	Real estate held for development is reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of a particular real estate property exceeds the estimated net realizable value. During the years ended June 30, 2014, 2013, and 2012, the Company experienced deteriorated real estate conditions which indicated real estate held for development could have carrying values higher than their net realizable value. Consequently, the Company obtained third party valuations and recorded impairment charges of $0.6 million, $1.1 million, and $8.1 million in the years ended June 30, 2014, 2013, and 2012, respectively. Impairments related to legacy and non-core operations for the years ended June 30, 2014, 2013, and 2012 were $0.6 million, $1.0 million, and $8.1 million, respectively. Impairments related to the Real Estate segment for the years ended June 30, 2014, 2013, and 2012 were zero, $0.1 million, and zero, respectively.
Deferred Charges and Other	'
	Deferred Charges and Other
	Deferred charges and other is comprised primarily of deferred financing costs. Deferred financing costs consist of capitalized legal and other fees directly related to the issuance of debt securities, net of accumulated amortization. These costs are amortized by methods that approximate the effective interest method over the respective term of the applicable debt instrument and recorded to interest expense.
Goodwill and Intangible Assets	'
	Goodwill and Intangible Assets
	Goodwill represents the excess of purchase price over the fair value of net assets acquired in a business combination. Goodwill is not amortized, but is tested for impairment annually as of June 30th and at any time when events or circumstances suggest impairment may have occurred. The Company has reporting units with allocated goodwill in both the Mountain and Real Estate segments.
	The testing for impairment consists of a comparison of the fair value of the reporting unit with its carrying amount. If the carrying amount of the reporting unit, including goodwill, exceeds the fair value, an impairment will be recognized equal to the difference between the carrying value of the reporting unit goodwill and the implied fair value of the goodwill. For the testing of goodwill for impairment, the Company determines the estimated fair value of its reporting units based upon a discounted future cash flow analysis.
	The Company's major definite-lived intangible asset categories and estimated useful lives are as follows:
	Intangible Asset Category		Estimated Life in Years
	Permits and licenses			20-45
	Trademarks and trade names			20-Oct
	Customer relationships			8
	Other			20-Aug
Long-lived Assets	'
	Long-lived Assets
	The Company evaluates potential impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment will be recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value.
Deferred Revenue and Deposits	'
	Deferred Revenue and Deposits
	Deferred revenue and deposits are comprised primarily of season pass revenue, lodging and tour deposits, deposits on real estate sales and mountain club initiation deposits. Deferred revenue relating to the sale of season passes is recognized throughout the season based on the estimated number of skier visits based on historical data. Lodging and tour deposits deferred revenue is recognized when the related service is provided. Deferred revenue relating to real estate deposits is recognized upon closing of the sale. Deferred revenue relating to mountain club initiation deposits is recognized on a straight-line basis over the estimated membership terms.
Self-Insured Liabilities	'
	Self-Insured Liabilities
	The Company has a policy of self-insuring when the expected losses from self-insurance are low relative to the cost of purchasing third-party insurance at various deductible levels. The self-insurance program includes workers’ compensation benefits in the United States and medical, property, automobile and general liability coverage in the United States and Canada. An accrual for self-insured liabilities is recorded based on management’s best estimate of the ultimate cost to settle claims considering historical claims experience, claims filed and the advice of actuaries and plan administrators.
	Liabilities for insurance-related assessments are not discounted and are included as part of accrued liabilities and other long-term liabilities on the consolidated balance sheets. As of June 30, 2014 and 2013, the liability balances were $7.5 million and $8.3 million, respectively.
Revenue Recognition	'
	Revenue Recognition
	The Company earns revenue from a variety of sources. Revenue is recognized when the following criteria have been met: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the fee is fixed or determinable and the collection of funds is reasonably assured. The following describes revenue recognition for the Company's three segments:
	(i)	Mountain segment revenue is derived from a wide variety of sources, including sales of lift tickets (including season passes), ski school operations, dining operations, retail sales, equipment rentals, lodging operations and food and beverage operations. Persuasive evidence is obtained and collection of funds assured through cash transactions or credit card validation at the point of sale. Revenue is recognized as goods are delivered or services are performed. Season pass revenue, although primarily collected prior to the ski season, is recognized in our consolidated financial statements during the ski season based on the estimated average number of visits by season pass holders in each month during the ski season, which is based on historical three year average visitation by season pass holders at our resorts. Frequency product revenue is recognized as used, and unused portions are recognized based on the prior three year average usage for each frequency product.
	(ii)	Adventure segment revenue is derived from a variety of sources, including all-inclusive packages for stays and tours for heli-skiing, mountaineering and hiking at Company owned and leased resorts, as well as ancillary revenue from helicopter maintenance and repair services, leasing, and off-season fire suppression services. Revenue is recognized as goods are delivered or services are performed. For CMH adventure vacation packages, payments in advance are recognized as revenue as goods are delivered or services are performed.
	(iii)	The Real Estate segment earns revenue from IRCG, IHM and Playground. During the fiscal years presented, there were no active development projects or development revenue. IRCG generates revenue from the sale of vacation points, management of Club Intrawest properties, an unaffiliated, not-for-profit entity, management of a private exchange company, and income on the receivables portfolio. Vacation points revenue associated with membership in the vacation ownership business of IRCG is recognized when the purchaser has paid the amount due on closing, all contract documentation has been executed and all other significant conditions of sale are met. The Company follows real estate time-sharing accounting principles, which set out specific guidelines for assessing whether the buyer’s initial and continuing investments are adequate to demonstrate a commitment to pay for the property. Such a demonstration is required for the seller of a time-sharing arrangement to recognize profit by the full accrual method. Sales are recorded upon closing when profitability can be determined and collectability can be reasonably assured. Buyers can finance a portion of the sales price through nonrecourse loans. IHM generates revenue from managing rental operations at the Honua Kai Resort and Spa in Maui, Hawaii and the Westin Monache Resort in Mammoth Lakes, California. Playground earns revenue from the commissions on the sales of real estate. The Company also manages commercial real estate for owned properties and third parties.
	Commission revenue from brokerage operations for the Company owned real estate is included in Real Estate revenue and is recognized at the time an offer of sale is closed by the purchaser or all other contractual obligations have been satisfied. Commission revenue for third-party projects from real estate brokerage operations is included in Real Estate revenue and is recognized when the deals listing agreement is executed.
Advertising Costs	'
	Advertising Costs
	The Company expenses advertising costs at the time such advertising commences. Advertising costs are classified in operating expenses on the consolidated statements of operations and were $16.8 million, $14.4 million and $12.7 million for the years ended June 30, 2014, 2013, and 2012, respectively.
Income Taxes	'
	Income Taxes
	Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between tax bases of assets and liabilities and book basis reported in the 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. To the extent that it is considered to be more likely than not that some or all of the deferred tax assets will not be realized, a valuation allowance is provided.
	The Company recognizes accrued interest related to uncertain tax positions as a component of income tax expense. Penalties, if incurred, are recorded in operating expenses in the consolidated statements of operations.
Foreign Currency	'
	Foreign Currency
	The consolidated financial statements are presented in United States dollars (“USD”). The Company’s Canadian subsidiaries generally have the Canadian dollar (“CAD”) as their functional currency.
	The accounts of entities where the USD is not the functional currency are translated into USD using the exchange rate in effect at the balance sheet date for asset and liability amounts and at the monthly average rate in effect for the period for amounts included in the determination of income. Cumulative unrealized gains or losses arising from the translation of the financial position of these subsidiaries into USD are included in total equity as a component of accumulated other comprehensive income (loss) ("AOCI").
	Exchange gains or losses arising from transactions that are denominated in foreign currencies into the applicable functional currency are included in the determination of income and are classified in other income (expense), net in the consolidated statement of operations.
Share-Based Compensation	'
	Share-Based Compensation
	On January 30, 2014, the Company’s Compensation Committee of the Board of Directors approved the terms of the 2014 Omnibus Incentive Plan (the “Plan”), which allows the Company to grant share-based compensation awards in a variety of forms such as options, stock appreciation rights, restricted stock, restricted stock units, stock bonuses, other stock-based awards and cash awards as part of the Company’s long-term incentive compensation plan.
	Awards granted under the Plan generally vest based on a service condition as defined in each award. Unless otherwise determined or evidenced in an award agreement, in the event that (i) a change in control occurs, as defined in the Plan, and (ii) a participant’s employment or service is terminated without cause within 12 months following the change in control, then (a) any unvested or unexercisable portion of any award carrying a right to exercise shall become fully vested and exercisable, and (b) the restrictions, deferral limitations, payment conditions and forfeiture conditions applicable to any award will lapse and such unvested awards will be deemed fully vested and any performance conditions imposed with respect to such awards will be deemed to be fully achieved.
	Compensation expense is measured based on the fair value of the award on the date of grant, net of estimated forfeitures, and is recognized as expense on a straight-line basis over the requisite service period.
Employee Benefit Plans	'
	Employee Benefit Plans
	Substantially all of the Company’s employees are covered by Company-sponsored 401(k) plans in the U.S. and defined contribution plans in Canada. The Company’s contributions to these plans are based on a percentage of employee compensation. These plans are funded on a current basis.
	In addition, certain current and former employees are covered by noncontributory defined benefit pension plans. These plans are funded in conformity with the funding requirements of applicable government regulations. Generally, benefits are based on age, years of service and level of compensation during the final years of employment. The Company accounts for these defined benefit plans by accruing its obligations under the employee benefit plans and the related costs as the underlying services are provided. The Company has frozen the plans and no further service benefits are being earned by plan participants in the defined plans.
	The funded status of defined benefit plans is recognized entirely on the consolidated balance sheets. The amount recognized as an asset or liability for pension and other postretirement benefit plans is measured as the difference between the benefit obligation and the fair value of plan assets. Overfunded plans are aggregated and recognized as an asset while underfunded plans are aggregated and recognized as a liability. Actuarial gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net pension expense are recognized in accumulated other comprehensive income (loss) net of income tax effects. Actuarial gains and losses are comprised of changes in the amount of either the projected benefit obligation (for pension plans), the accumulated benefit obligation (for other postretirement plans) or differences between actual and expected return on plan assets and from changes in assumptions. The Company measures its pension assets and liabilities as of June 30th of each year.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. A three-tier fair value hierarchy, which is described below, prioritizes the inputs used in measuring fair value:
	•	Level 1 – Quoted prices for identical instruments in active markets.
	•	Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations, in which all significant inputs are observable in active markets.
	•	Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
	The Company has various financial instruments, including cash and cash equivalents, receivables, payables, accrued liabilities and debt obligations. Due to their short-term nature, or, in the case of note receivables, their market comparable interest rates, the instruments’ book value approximates their fair value.
	The fair value of the FY14 Lien Loan was estimated using quoted prices for our instruments in markets that are not active and was considered a Level 2 measure. The fair value of the FY13 Lien Loans was estimated based on Level 3 inputs using discounted future contractual cash flows and a market interest rate based on published corporate borrowing rates for debt instruments with similar terms and average maturities, with adjustments for credit risk. The fair value of other obligations was estimated based on Level 3 inputs using discounted cash flow analyses based on assumptions that management believed were consistent with market participant assumptions.
	The Company’s long-term debt obligations are not measured and carried at fair value on a recurring basis. The Company’s debt is initially recorded based upon historical cost. The fair value of debt does not represent the amounts that will ultimately be paid upon the maturities of the loans.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	The Company engages in activities that expose it to market risks including the effects of changes in interest rates and exchange rates. Financial exposures are managed as an integral part of the Company’s risk management activities, which seek to reduce the potentially adverse effect that the volatility of interest rates or exchange rates may have on operating results.
	As of June 30, 2014 and 2013, the Company had no significant outstanding derivative instruments. Prior to October 2008, the Company had outstanding interest rate swaps that were accounted for as cash flow hedges. The outstanding swap contracts were terminated on October 11, 2008, and the deferred loss previously recorded in AOCI is being recognized in earnings during the period that the hedge covered, which ends on March 31, 2017. Approximately $1.8 million of deferred losses related to the terminated interest rate swaps will be amortized from AOCI into interest expense in the next 12 months.
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, but these investments may be in excess of regulatory insurance limits. The Company does not enter into financial instruments for trading or speculative purposes. Concentration of credit risk with respect to trade and notes receivables is limited due to the large number of customers and small transactions associated with the Company’s consumer and retail operations and the wide variety of customers and markets in which the Company transacts business. No customer represented 10% or more of total revenue or receivables during the years ended June 30, 2014, 2013, and 2012. Where the Company provides financing, the Company performs ongoing credit evaluations of its customers and generally does not require collateral, but does require advance deposits on certain transactions.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2012, the Financial Accounting Standards Board (“FASB”) issued ASU 2012-02, Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. This update amends ASU 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment and permits an entity first to assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with Subtopic 350-30, Intangibles - Goodwill and Other - General Intangibles Other than Goodwill. The Company adopted the provisions of the ASU effective July 1, 2013. The adoption of ASU 2012-02 did not have a material impact on the Company’s financial position, results of operations or cash flows.
	In February 2013, the FASB issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The ASU does not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the ASU requires an entity to provide information about the amounts reclassified out of AOCI by component. Specifically, the ASU requires the Company to present either in a single note or parenthetically on the face of the financial statements the effect of significant amounts reclassified from each component of AOCI based on its source and the income statement line items affected by the reclassification. If a component is not required to be reclassified to net income in its entirety, the Company would instead cross- reference to the related note for additional information. The guidance included in ASU 2013-02 was effective for the Company beginning July 1, 2013 and was applied prospectively. The adoption of this authoritative guidance did not have an impact on the Company’s financial position, results of operations or cash flows.
	In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360):  Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.  This update raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures for discontinued operations as well as certain other disposals that do not meet the definition of a discontinued operation.  The guidance is effective for annual periods beginning on or after December 15, 2014 with early adoption permitted only for disposals that have not been previously reported.  The Company does not anticipate that the adoption of ASU 2014-08 will have a material impact on the Company's financial position, results of operations or cash flows.
	On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective July 1, 2017. Early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is currently in the process of evaluating the impact that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
