Report of Independent Registered Public Accounting Firm

The Administrative Committee
Intrawest 401(k) Retirement Plan:

We have audited the accompanying statements of net assets available for plan benefits of the Intrawest 401(k) Retirement Plan (the Plan) as of December 31, 2005 and 2004, and the related statements of changes in net assets available for plan benefits for the years then ended. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts, and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Intrawest 401(k) Retirement Plan as of December 31, 2005 and 2004, and the changes in net assets available for plan benefits for the years then ended in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets held (at end of year) and delinquent participant contributions are presented for purposes of additional analysis and are not a required part of the basic financial statements, but are supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure Under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan’s management. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole

INTRAWEST 401(k) RETIREMENT PLAN

Notes to Financial Statements

December 31, 2005 and 2004

(1)	Description of Plan
	The following description of the Intrawest 401(k) Retirement Plan (the Plan) provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan’s provisions.

(a)	General
	The Plan is a defined contribution plan established by Stratton Corporation (Stratton) in June 1978. All employees of the Stratton Corporation, Intrawest U.S. Holdings Inc., Snowshoe Mountain, Inc., Copper Mountain, Inc., Intrawest California Holdings, Inc., Mountain Creek Resort, Inc., Intrawest Resort Ownership U.S. Corp., Intrawest Retail Group, Inc., Sandestin Resort & Club, Inc., Playground Destination Properties, Inc., Moguls, Inc., IRG Restaurant Company, Resort Reservations Network, Inc., Intrawest Shared Services, Inc., Intrawest U.S. Commercial Property Management, Inc., Intrawest Golf Holdings, Inc., Intrawest Resorts, Inc., Intrawest Hospitality Management Inc., Intrawest Golf Management, Inc., Big Island Country Club, and Intrawest/Winter Park Operations Corporation (collectively referred to as the Company) who have completed one year of service of at least 1,000 hours and have attained the age of 21 are eligible to participate in the Plan. Participation is voluntary. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA), as amended.
(b)	Contributions
	Each year, participants may contribute pretax annual compensation, as defined in the Plan, not to exceed $14,000 and $13,000 ($18,000 and $16,000 if age 50 or older) in 2005 and 2004, respectively. Participants may also contribute amounts representing rollovers from other qualified defined benefit or contribution plans. The Plan administrator has identified $4,753 and $104,252 of contributions made by certain employees in excess of amounts allowed by the Internal Revenue Code during 2005 and 2004, respectively. These excess contributions will be returned to the employees and are recorded in other liabilities as of December 31, 2005 and 2004.
	Subject to certain limitations, the Company will match participant contributions at a rate determined by the sponsor of the Plan. The Plan also provides for discretionary Company contributions, which are allocated to participants’ accounts based on the relative compensation of participants. Company matching contributions were equal to 50% of the first 6% of compensation deferred during 2005 and 2004. There were no discretionary Company contributions during 2005 and 2004.
(c)	Participant Accounts
	Each participant’s account is credited with the participant’s contributions, Company matching and discretionary contributions, and earnings (losses) thereon.
(d)	Vesting
	Participants are immediately vested in their contributions plus earnings thereon. Employees participating in the plan prior to January 1, 1998 are 100% vested in Company contributions.

INTRAWEST 401(k) RETIREMENT PLAN

Notes to Financial Statements

December 31, 2005 and 2004

For participants enrolling in the Plan subsequent to January 1, 1998, Company contributions vest based upon the following schedule:

	Vesting
Years of service	percentage
1		20	%
2		40
3		60
4		80
5		100

(e)	Investment Options
	Upon enrollment in the Plan, a participant may direct employee and Company contributions into various investment options. Participants may change their investment options daily.
(f)	Participant Loans Receivable
	Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their vested account balance. Loan terms range from one to five years. The loans are secured by the balance in the participant’s account. Interest rates on participant loans range from 5% to 11%.
(g)	Hardship Withdrawals
	Participants may receive hardship withdrawals for reasons of financial hardship. Participation in the Plan is suspended for six months following the receipt of a hardship withdrawal.
(h)	Payment of Benefits
	Participants are entitled to receive benefit payments in the form of a lump sum payment or installments equal to 100% of their accrued benefit upon reaching the early retirement age of 55, the normal retirement age of 65, termination of employment, or upon death or disability. The accrued benefit includes the sum of the value of participant’s contributions, allocations of earnings (losses), and the vested portion of Company contributions. Participants employed beyond age 591/2 may withdraw their accrued benefit.
(i)	Forfeited Accounts
	Forfeited accounts are used by the Company to either satisfy its future matching contribution requirements or to pay administrative expenses of the Plan. At December 31, 2005 and 2004, forfeited accounts totaled $222,670 and $139,970, respectively. In 2005 and 2004, the amount of forfeitures used to pay Plan expenses was approximately $113,000 and $141,000, respectively. The remaining forfeitures are available to offset future Company matching contributions.

(2) Summary of Significant Accounting Policies

(a)	Basis of Accounting
	The financial statements of the Plan are prepared using the accrual basis of accounting.
(b)	Valuation of Investments
	Investments in mutual funds and common stocks are valued at fair value determined by quoted market price. Money market accounts are stated at cost, which approximates fair value. Loans to participants are recorded at the amount borrowed less repayments, which approximates fair value. Investment transactions are recorded on the trade date. Interest is recorded when earned. Dividends are recorded on the ex-dividend date.
(c)	Administrative Expenses and Distributions
	Administrative expenses are either paid directly by the Plan or through the use of forfeited nonvested accounts. Distributions are recorded when paid.
(d)	Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 additions and deductions in net assets during the reporting period. Actual results could differ from those estimates.
(e)	Realized and Unrealized Gains and Losses
	Net realized and unrealized appreciation in the fair value of investments is determined as the difference between the market value at the beginning of the year (or date purchased during the year) and selling price or year-end market value. Such income (loss) is allocated to participants’ accounts based on relative participant account balances.

(3)	Plan Termination
	Although the Company has not expressed any intention to terminate the Plan, it may do so at any time. Under the provisions of the Plan, if the Plan is terminated, the accounts of all participants would become vested and the Plan trustee would distribute the assets in the Plan to participants.
	Additionally, the Plan sponsor may amend the Plan at any time without the consent of any participant or any beneficiary, provided that no amendment deprives any participant of the participant’s vested accrued benefit.

Fidelity Retirement Money Market		3,028,420		2,837,571
Fidelity Mid-Cap Stock		—		2,706,466

During 2005 and 2004, the Plan’s investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated in value as follows:

	2005		2004
Mutual funds	$	3,859,345		4,279,634
Intrawest Corporation common stock		346,661		245,667
	$	4,206,006		4,525,301

Income Taxes

The Internal Revenue Service has determined and informed the Company by a letter dated October 2, 2002 that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (IRC). The Plan has been amended since receiving the determination letter. However, in the opinion of the Plan administrator, the plan and its underlying trust are designed and are currently being operated in compliance with the applicable provisions of the IRC.

(6)	Nonexempt Transactions
	During 2005 and 2004, the Plan did not deposit certain employee contributions on a timely basis as required by ERISA. Such untimely deposits are deemed to be a loan with a party in interest and are prohibited under Section 406(a) of ERISA. Employee contributions deposited untimely amounted to $178,510 and $238,673 in 2005 and 2004, respectively, and resulted in lost earnings of $773 and $1,419, respectively. The Company has made additional contributions for the years listed to credit these lost earnings to participant accounts.
(7)	Risks and Uncertainties
	The Plan provides for various investments. Investments, in general, are exposed to various risks, such as significant world events, interest rate, credit, and overall market volatility risk. Due to the level of risk associated with certain investments, it is reasonably possible that changes in the value of investments will occur in the near term and that such changes could materially affect the amounts reported in the statements of net assets available for plan benefits.
(8)	Related Party Transactions
	The Plan invests in certain investments managed by Fidelity Management Trust Company, the Plan’s trustee; therefore, these transactions qualify as party-in-interest transactions. In addition, the Plan has an investment in Intrawest Corporation common stock which qualifies as party-in-interest transactions.
