During the first four years following closing of the transaction, Primero will deliver to Silver Wheaton a per annum amount equal to the first 3.5 million ounces of payable silver produced at San Dimas and 50% of any excess, plus Silver Wheaton will receive an additional 1.5 million ounces of silver per annum to be delivered by Goldcorp. Beginning in the fifth year after closing, Primero will deliver to the Company a per annum amount equal to the first 6 million ounces of payable silver produced at San Dimas and 50% of any excess. Goldcorp will continue to guarantee the delivery by Primero of all silver produced and owing to the Company until 2029. Primero has provided Silver Wheaton with a right of first refusal on any metal stream or similar transaction it enters into.
On September 12, 2010, Goldcorp announced that its world-class gold-silver-lead-zinc Peñasquito mine achieved commercial production with peak throughput rates as high as 105,000 tonnes per day. The ramp up to full production capacity of 130,000 tonnes per day is anticipated by early 2011. Annual production attributable to Silver Wheaton from the mine is expected to average approximately 7 million ounces of silver over the estimated 22 year mine life.
On November 3, 2010, the Company acquired, by way of private placement, 3.0 million common shares of Bear Creek Mining Corporation (“Bear Creek”) at a price of Cdn$6.40 per share, for total consideration of Cdn$19.1 million.

Barrick Gold Corporation’s world-class gold-silver Pascua-Lama project is forecast to commence production in the first half of 2013, with detailed engineering and procurement nearing completion and earthworks well underway. Once in production, Pascua-Lama is forecast to be one of the largest and lowest cost gold mines in the world with an expected mine life in excess of 25 years. In its first five years of operation, Silver Wheaton’s attributable silver production is expected to average 9 million ounces annually.

Silver Wheaton Corp. (“Silver Wheaton” or the “Company”) is a mining company which generates its revenue primarily from the sale of silver. The Company is listed on the New York Stock Exchange (symbol: SLW) and the Toronto Stock Exchange (symbol: SLW). In addition, the Company has share purchase warrants that trade on the Toronto Stock Exchange (symbol: SLW.WT.U).

To date, the Company has entered into fourteen long-term silver purchase agreements and two long-term precious metal purchase agreements whereby Silver Wheaton acquires silver and gold production from the counterparties for a per ounce cash payment at or below the prevailing market price. Attributable silver and gold as referred to in this Management’s Discussion and Analysis and Financial Statements is the silver and gold production to which Silver Wheaton is entitled pursuant to the various purchase agreements. During the year ended December 31, 2010, the per ounce price paid by the Company for silver and gold under the agreements averaged $3.97 and $300, respectively. The primary drivers of the Company’s financial results are the volume of silver production at the various mines and the price of silver realized by Silver Wheaton upon sale.

BARRICK

On September 8, 2009, the Company entered into an agreement with Barrick to acquire an amount equal to 25% of the life of mine silver production from its Pascua-Lama project, as well as 100% of the silver production from its Lagunas Norte, Pierina and Veladero¹mines until the end of 2013. Silver Wheaton will make total upfront cash payments of $625 million, of which $350 million has been paid to date. The remaining $275 million is payable in annual installments of $137.5 million due on the second and third anniversaries of the transaction.

Barrick has provided Silver Wheaton with a completion guarantee, requiring them to complete Pascua-Lama to at least 75% of design capacity by December 31, 2015. During 2014 and 2015, Silver Wheaton will be entitled to the silver production from the currently producing mines to the extent of any production shortfall at Pascua-Lama, until Barrick satisfies the completion guarantee. If the requirements of the completion guarantee have not been satisfied by December 31, 2015, the agreement may be terminated by Silver Wheaton. In such an event, Silver Wheaton will be entitled to the return of the upfront cash consideration of $625 million less a credit for silver delivered up to the date of that event.

In November 2010, Argentina passed a federal glacier protection law that bans new mining exploration and exploitation activities on glaciers and in the “peri-glacial” environment, and subjects ongoing mining activities to an environmental audit. If such an audit identifies significant impacts on glaciers and the peri-glacial environment, the relevant authority is empowered to take action, which according to the legislation could include the suspension or relocation of the activity. As stated by Barrick in its 2010 year end Management Discussion & Analysis, Barrick’s view is that its activities do not take place on glaciers and are undertaken pursuant to existing environmental approvals issued on the basis of comprehensive environmental impact studies that fully considered potential impacts on water resources, glaciers and other sensitive environmental areas. Barrick also states that it believes that the new federal law is unconstitutional, and that it believes it is legally entitled to continue its current activities on the basis of existing approvals. In this regard, in November 2010, the Federal Court in the Province of San Juan granted injunctions, based on the unconstitutionality of the federal legislation, suspending the application of the legislation in the Province and in particular relating to Veladero and Pascua-Lama. The actions have been moved to the National Supreme Court of Justice of Argentina to determine the constitutionality of the legislation. It is possible that others may attempt to bring legal challenges seeking to restrict Barrick’s activities based on the new federal law. Barrick indicates in its disclosure that it will vigorously oppose any such challenges.


¹Silver Wheaton's attributable silver production is subject to a maximum of 8% of the silver contained in the ore mined at Veladero during the period.

SILVER WHEATON ANNUAL REPORT [6]

As of December 31, 2010, Barrick has delivered in excess of 3 million ounces of silver to the Company under the agreement, generating cumulative operating cash flows of $52 million. As at December 31, 2010, the Company’s 25% share of the Pascua-Lama proven and probable silver reserves was 167.9 million ounces, measured and indicated silver resources was 41.4 million ounces and inferred silver resources was 3.7 million ounces (as described in the Reserves and Resources section of this Management’s Discussion and Analysis). In addition, the Company’s estimated share of the silver resources contained in the Lagunas Norte, Pierina, and Veladero mines is 63.9 million ounces of proven and probable silver reserves.

Total corporate (recovery) costs	$	(7,060	)	$	16,498		$	86,086

For the year ended December 31, 2010, corporate costs decreased by $23.6 million over the comparable period in the previous year, primarily as a result of: (i) a non-cash $10.7 million mark-to-market gain relating to warrants held as long-term investments; (ii) a non-cash future income tax recovery of $13.6 million relating to the recognition of previously unrecognized future income tax assets; and (iii) a $5.9 million gain resulting from the disposition of the La Negra silver purchase agreement, (as discussed in the Silver and Gold Interests section of this Management’s Discussion and Analysis) reflected in Other income. These gains were partially offset by an increase in total general and administrative costs of $7.4 million, attributable to: (i) a $3.7 million increase in stock based compensation (a non-cash item); and (ii) a $3.7 million increase in general and administrative expenses, primarily due to increased corporate activity.

The long-term investments held by the Company consist of both equity securities and warrants of publicly traded companies which are held for long-term investment purposes. The equity securities are classified as available-for-sale because the Company intends to hold the investments for more than one year. Unrealized holding gains and losses related to available-for-sale investments are excluded from net earnings and are included in other comprehensive income until such gains or losses are either: (i) realized or (ii) an other-than-temporary impairment is determined to have occurred. As at December 31, 2008, management concluded that these available-for-sale investments were other-than-temporarily impaired; as a result, the carrying value of these investments was written down to their fair values as of such date, resulting in a $64.0 million loss being recorded in net earnings. During 2009 and 2010, the carrying value of these investments increased by $193.1 million with the unrealized gain being reflected in Other Comprehensive Income.

Warrants meet the definition of a derivative and are marked-to-market on a quarterly basis with any gains or losses included in net earnings in the period they occur.

The Company’s future income tax expense or recovery in a given period is largely determined by changes in the unrealized gains or losses recorded with respect to its long-term investments. As a result of a significant increase in the value of the long-term investments during 2010, the Company recorded a future income tax liability with the associated $14.4 million future income tax expense being reflected as a component of other comprehensive income. The Company has future tax assets relating to tax losses and tax deductions which had not been previously recognized. The Company has reversed its valuation allowance and recognized these future income tax assets, which partially offset this future tax liability, with the resulting $13.6 million future income tax recovery being reflected in net earnings.

The Company incurred interest costs of $24.5 million during 2010, of which $23.1 million represents accreted interest on the future payments due in relation to the Barrick silver interest, with the remainder being attributable to interest on bank debt. All of the interest costs incurred during 2010 have been capitalized in relation to the Peñasquito, Keno Hill and Barrick silver interests. For the same period in 2009, the Company incurred interest costs of $10.0 million, of which $6.1 million represents accreted interest on the future payments due in relation to the Barrick silver interest, with the remainder being attributable to interest on bank debt. All of the interest costs incurred during 2009 were capitalized in relation to the Peñasquito, Keno Hill and Barrick silver interests.

SILVER WHEATON ANNUAL REPORT [16]

Non-GAAP Measures

Silver Wheaton has included, throughout this document, certain non-GAAP performance measures, including total cash costs of silver and gold on a sales basis, as well as operating cash flows per share and cash operating margin. These non-GAAP measures do not have any standardized meaning prescribed by GAAP, nor are they necessarily comparable with similar measures presented by other companies. Cash costs are presented as they represent an industry standard method of comparing certain costs on a per unit basis. Cash operating margin is defined as the realized selling price less total cash cost per silver equivalent ounce. The Company believes that certain investors use this information to evaluate the Company’s performance. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. During the year ended December 31, 2010, the Company’s total cash costs, which were equivalent to the Company’s cost of sales in accordance with GAAP, were $3.97 per ounce of silver and $300 per ounce of gold (2009 – $3.97 per ounce of silver and $300 per ounce of gold).

Liquidity and Capital Resources

As at December 31, 2010, the Company had cash and cash equivalents of $428.6 million (December 31, 2009 - $227.6 million) and working capital of $265.1 million (December 31, 2009 – $64.2 million). The Company invests surplus cash in short-term, high credit quality, money market instruments.

During the year ended December 31, 2010, the Company generated operating cash flows of $319.8 million compared with $165.9 million during 2009, with the increase primarily as a result of increased silver equivalent ounces sold in addition to a higher realized average silver price.

During 2010, the Company had net cash inflows from financing activities of $79.8 million, primarily comprised of proceeds in the amount of $108.4 million from share purchase options and share purchase warrants exercised during the period, partially offset by scheduled principal repayments of $28.6 million relating to the Company’s non-revolving bank debt facility. During 2009, the Company had net cash inflows from financing activities of $276.3 million including the receipt of $495.8 million in net proceeds from two equity financings offset by the net repayment of $242.1 million of debt outstanding under the Company’s debt facilities. In addition, during 2009, the Company received proceeds of $22.6 million from the exercise of share purchase options and share purchase warrants.

During 2010, the Company had net cash outflows relating to investing activities of $201.3 million, primarily related to the scheduled upfront payment of $137.5 million to Barrick and upfront payments totaling $32.6 million to Alexco in addition to the acquisition of long-term investments totaling $54.1 million, which were partially offset by the $25 million proceeds received from Aurcana for the disposal of the La Negra silver purchase agreement. During 2009, the Company had net cash outflows relating to investing activities of $221.2 million, which related primarily to the upfront cash payment made to Barrick.

As at December 31, 2010, the Company has cash on hand of $428.6 million and $400 million available under its revolving bank debt facility as more fully described in Note 6 to the Financial Statements. In the opinion of management, cash flows, cash balances and available credit facilities are sufficient to support the Company’s normal operating requirements on an ongoing basis.

On November 17, 2010, Revett announced a share consolidation (reverse stock split) of common shares on a one for five basis, effective November 19, 2010. As a result, at December 31, 2010, Silver Wheaton owned 5.0 million common shares and warrants exercisable to acquire an additional 0.2 million common shares, representing approximately 16% of the outstanding shares of Revett. At December 31, 2010, the fair value of the Company’s investment in Revett was $25.6 million.

MINES MANAGEMENT

At December 31, 2010, Silver Wheaton owned 2.5 million common shares of Mines Management, Inc. (“Mines Management”), representing approximately 11% of the outstanding shares of Mines Management. At December 31, 2010, the fair value of the Company’s investment in Mines Management was $10.4 million.

OTHER

At December 31, 2010, Silver Wheaton owned common shares and share purchase warrants of several publicly traded mineral exploration, development and mining companies. As Silver Wheaton’s investment represents less than 10% of the outstanding shares of each of the respective companies, these investments have been reflected in these financial statements as part of Other long-term investments. At December 31, 2010, the fair value of the Other long-term investments was $121.8 million.

CONTINGENCIES

Due to the size, complexity and nature of the Company’s operations, various legal and tax matters are outstanding from time to time. In the opinion of management, these matters will not have a material effect on the Company’s consolidated financial position or results of operations.

SHARE CAPITAL

During the year ended December 31, 2010, the Company received cash proceeds of $32.3 million (2009 - $8.8 million) from the exercise of 2,813,773 share purchase options (2009 – 1,945,305 share purchase options) at a weighted average exercise price of Cdn$11.85 per option (2009 – Cdn$4.86 per option).

During the year ended December 31, 2010, the Company received proceeds of $76.1 million, primarily from the exercise of Series “B” warrants which expired on December 22, 2010, resulting in the issuance of 7,738,030 common shares.

During the year ended December 31, 2009, the Company received proceeds of $13.8 million from the exercise of share purchase warrants which expired on August 5, 2009, and the Series “A” warrants which expired on November 30, 2009, resulting in the issuance of 3,455,636 common shares.

On February 12, 2009, the Company announced that it had closed an equity financing, raising gross proceeds of Cdn$287.5 million ($230.4 million) through the issuance of 35,937,500 common shares at Cdn$8.00 per share (approximately $6.41 per share). The proceeds were primarily used to repay outstanding debt under the revolving bank loan facility.

On May 21, 2009, the Company closed the acquisition of Silverstone through the issuance of 23,434,332 common shares and 1,367,364 share purchase options of Silver Wheaton which were issued on conversion of previously issued fully vested share purchase options of Silverstone. Including acquisition costs, the transaction was valued at approximately $152 million.

SILVER WHEATON ANNUAL REPORT [20]

On September 30, 2009, in conjunction with the Barrick acquisition, the Company closed an equity financing, raising gross proceeds of $287.5 million through the issuance of 25,903,750 common shares at $11.10 per share. On October 21, 2009, $140.2 million of the net proceeds from the equity financing were used to repay the temporary draw under the Company’s revolving bank debt facility which had been utilized to partially finance the initial upfront cash payment of $212.5 million made to Barrick.

As of March 23, 2011, there were 353,202,255 outstanding common shares, 2,251,249 share purchase options, 162,265 restricted share units and 2,716,131share purchase warrants.

Risks and Uncertainties

The primary risk factors affecting the Company are set forth below. For discussion of additional risk factors, please refer to the Company’s Annual Information Form, which is available on the Company’s website, www.silverwheaton.com, and on SEDAR, www.sedar.com, or is available upon request from the Company.

COMMODITY PRICES

The price of the common shares and the Company’s financial results may be significantly adversely affected by a decline in the price of silver or gold. The price of silver and gold fluctuates widely, especially in recent years, and is affected by numerous factors beyond the Company’s control, including but not limited to, the sale or purchase of silver and gold by various central banks and financial institutions, interest rates, exchange rates, inflation or deflation, fluctuation in the value of the United States dollar and foreign currencies, global and regional supply and demand, and the political and economic conditions of major silver and gold producing countries throughout the world.

In the event that the prevailing market price of silver or gold is at or below the price at which the Company can purchase such pursuant to the terms of the agreements associated with its silver and gold interests, the Company will not generate positive cash flow or earnings.

RISKS RELATING TO MINING OPERATIONS

To the extent that they relate to the production of silver and gold from, or the continued operation of, the San Dimas mine, the Zinkgruvan mine, the Yauliyacu mine, the Stratoni mine, the Mineral Park mine, the Los Filos mine, the Peñasquito mine, the Campo Morado mine, the Keno Hill mine, the Neves-Corvo mine, the Cozamin mine, the Minto mine, the Barrick mines (including the Pascua-Lama project), the Aljustrel mine, the Rosemont project or the Loma de La Plata project (collectively, the “Mining Operations”), the Company will be subject to the risk factors applicable to the operators of such mines or projects, including the following as more fully described in the Company’s Annual Information Form: government regulations; international operations; exploration, development and operating risks; environmental regulation; permitting; compliance with laws; infrastructure; mineral reserve and mineral resource estimates; need for additional mineral reserves; land title; commodity price fluctuations; additional capital; and permitting, construction, development and expansion risk.

NO CONTROL OVER MINING OPERATIONS

The Company has agreed to purchase a certain percentage of the silver (and in some cases gold) produced by the Mining Operations. The Company is not directly involved in the ownership or operation of mines and has no contractual rights relating to the operation of the Mining Operations. As a result, the cash flow of the Company is dependent upon the activities of third parties which creates the risk that at any time those third parties may: (a) have business interests or targets that are inconsistent with those of the Company, (b) take action contrary to the Company’s policies or objectives, (c) be unable or unwilling to fulfill their obligations under their agreements with the Company, or (d) experience financial, operational or other difficulties, including insolvency, which could limit a third party’s ability to perform its obligations under the silver purchase agreements or the precious metals purchase agreements. Except in limited circumstances, the Company will not be entitled to any material compensation if such operations do not meet their forecasted silver or gold production targets in any specified period or if the operations shut down or discontinue their operations on a temporary or permanent basis. There can be no assurance that the silver or gold production from such properties will ultimately meet forecasts or targets. At any time, any of the operators of the Mining Operations may decide to suspend or discontinue operations.

TAXES

The Company’s operating profit is derived primarily from its subsidiaries, Silver Wheaton (Caymans) Ltd. and Silverstone Resources (Barbados) Corp., which are incorporated and operated in the Cayman Islands and Barbados, respectively, such that the Company’s profits are subject to minimal income tax.

SILVER WHEATON ANNUAL REPORT [21]

The introduction of new tax laws or regulations, or changes to, or differing interpretation of, existing tax laws or regulations in Canada, the Cayman Islands, Luxembourg, Barbados, the Netherlands or any of the countries in which the Mining Operations are located or to which shipments of silver or gold are made, could result in an increase in the Company’s taxes, or other governmental charges, duties or impositions. No assurance can be given that new tax laws or regulations will not be enacted or that existing tax laws or regulations will not be changed, interpreted or applied in a manner which could have a material adverse effect on the Company.

CREDIT AND LIQUIDITY RISK

The Company is exposed to various counterparty risks and liquidity risks including, but not limited to: (i) through the companies with which the Company has purchase agreements; (ii) through financial institutions that hold the Company’s cash and cash equivalents; (iii) through companies that have payables to the Company, including concentrate customers; (iv) through the Company’s insurance providers; and (v) through the Company’s lenders. The Company is also exposed to liquidity risks in meeting its operating expenditure requirements in instances where cash positions are unable to be maintained or appropriate financing is unavailable. These factors may impact the ability of the Company to obtain loans and other credit facilities in the future and, if obtained, on terms favourable to the Company. If these risks materialize, the Company’s operations could be adversely impacted and the trading price of the common shares could be adversely affected.

COMPETITION

The Company competes with other companies for silver and precious metals purchase agreements and similar transactions. Some of these companies may possess greater financial and technical resources than the Company. Such competition may result in the Company being unable to enter into desirable silver and precious metals purchase agreements or similar transactions, to recruit or retain qualified employees or to acquire the capital necessary to fund its silver and precious metals purchase agreements. Existing or future competition in the mining industry could materially adversely affect the Company’s prospects for entering into additional silver and precious metals purchase agreements in the future.

SILVER AND GOLD PRODUCED AS A BY-PRODUCT

Silver and gold are by-product metals at all of the Mining Operations, other than at the Keno Hill Mine and the Loma de La Plata Project, and therefore, the economic cut-off applied to the reporting of silver and gold reserves and resources will be influenced by changes in the commodity prices of other metals at the mines.

ACQUISITION STRATEGY

As part of the Company’s business strategy, it has sought and will continue to seek new exploration, mining and development opportunities in the resource industry. In pursuit of such opportunities, the Company may fail to select appropriate acquisition candidates or negotiate acceptable arrangements, including arrangements to finance acquisitions or integrate the acquired businesses and their personnel into the Company. The Company cannot assure that it can complete any acquisition or business arrangement that it pursues, or is pursuing, on favourable terms, or that any acquisitions or business arrangements completed will ultimately benefit the Company.

MARKET PRICE OF THE COMMON SHARES AND THE COMMON SHARE PURCHASE WARRANTS

The common shares are listed and posted for trading on the TSX and on the NYSE and the Company’s common share purchase warrants are listed and posted for trading on the TSX. An investment in the Company’s securities is highly speculative. Securities of companies involved in the resource industry have experienced substantial volatility in the past, often based on factors unrelated to the financial performance or prospects of the companies involved. The price of the common shares and the Company’s common share purchase warrants are also likely to be significantly affected by short-term changes in silver and gold prices, the Company’s financial condition or results of operations as reflected in its quarterly earnings reports, and the other risk factors identified herein.

SILVER WHEATON ANNUAL REPORT [22]

EQUITY PRICE RISK

The Company is exposed to equity price risk as a result of holding long-term investments in other exploration and mining companies. Just as investing in the Company is inherent with risks such as those set out in this Management’s Discussion and Analysis, by investing in these other companies, the Company is exposed to the risks associated with owning equity securities and those risks inherent in the investee companies. The Company does not actively trade these investments.

DIVIDEND POLICY

There can be no assurance that the Company will continue to declare a dividend on a quarterly, annual or other basis.

DEPENDENCE UPON KEY MANAGEMENT PERSONNEL

The Company is dependent upon a number of key management personnel. The Company’s ability to manage its activities will depend in large part on the efforts of these individuals. The Company faces intense competition for qualified personnel, and there can be no assurance that the Company will be able to attract and retain such personnel. The loss of the services of one or more of such key management personnel could have a material adverse effect on the Company.

OTHER RISKS

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenditures during the reporting period. Note 2 of the Company’s audited consolidated financial statements describes all of the significant accounting policies.

SILVER AND GOLD INTERESTS

Silver and gold interests are a significant asset of the Company, with a carrying value of $1.9 billion at December 31, 2010. This amount represents the capitalized expenditures related to the acquisition of the Mining Operations. Each of these mines estimates the reserves and resources relating to each agreement. Silver Wheaton uses these estimates to determine the estimated number of ounces that will be acquired from each operation and the cost of these assets is separately allocated to reserves, resources and exploration potential. The value allocated to reserves is classified as depletable and is depreciated on a unit-of-sale basis over the estimated recoverable proven and probable reserves at the mine corresponding to the specific agreement. The value associated with resources and exploration potential is the value beyond proven and probable reserves at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category as a result of the conversion of resources or exploration potential into reserves. Evaluations of the carrying values of each agreement are undertaken annually to determine if estimated undiscounted future net cash flows are less than the carrying value. Estimated undiscounted future net cash flows are calculated using estimated production, sales prices and purchase costs. If it is determined that the future net cash flows from an operation are less than the carrying value then a write-down is recorded with a charge to operations. At December 31, 2010, no write-down was required.

REVENUE RECOGNITION

Revenue from the sale of silver and gold is recognized in the accounts when persuasive evidence of an arrangement exists, title and risk passes to the buyer, collection is reasonably assured and the price is reasonably determinable. Selling prices are determined at the point revenue is recognized by reference to active and freely traded commodity markets, for example the London Bullion Market for commodities, in an identical form to the product sold.

Where the Company acquires silver or gold in concentrate form, final silver or gold prices are set on a specified future quotational period pursuant to the concentrate sales contracts with third-party smelters, typically one to three months after the shipment date, based on market silver or gold prices. Revenues and the associated cost of sales are recorded on a gross basis under these contracts at the time title passes to the buyer based on the forward price for the expected settlement period. The contracts, in general, provide for a provisional payment based upon provisional assays and quoted silver and gold prices. Final settlement is based on the average applicable price for a specified future period, and generally occurs from three to six months after shipment. Final settlement is based on smelter weights, settlement assays and is priced as specified in the concentrate sales contract. The Company’s provisionally priced sales contain an embedded derivative that is required to be separated from the concentrate sales contract for accounting purposes. The concentrate sales contract is the receivable from the sale of concentrates measured at the forward price at the time of sale. The embedded derivative does not qualify for hedge accounting. The embedded derivative is recorded on the balance sheet as a derivative asset in accounts receivable or as a derivative liability in accrued liabilities and is adjusted to fair value through revenue each period until the date of final settlement.

SILVER WHEATON ANNUAL REPORT [23]

At December 31, 2010, the Company had outstanding provisionally priced sales of $25.3 million consisting of 0.9 million ounces of silver and 3,600 ounces of gold, which had a fair value adjustment of approximately $805,000 associated with the embedded derivative. For each one cent per ounce change in realized silver price, revenue would vary (plus or minus) by approximately $8,800 and for each $1 per ounce change in the realized price of gold, revenue would vary (plus or minus) by approximately $3,600. At December 31, 2009, the Company had outstanding provisionally priced sales of $9.7 million consisting of 0.3 million ounces of silver and 3,300 ounces of gold, which had a fair value adjustment of approximately $175,000 associated with the embedded derivative. For each one cent per ounce change in realized silver price, revenue would vary (plus or minus) by approximately $3,400 and for each $1 per ounce change in the realized price of gold, revenue would vary (plus or minus) by approximately $3,300.

Financial Instruments

In order to mitigate the effect of short-term volatility in silver and gold prices, the Company will occasionally enter into forward contracts in relation to silver and gold deliveries it is highly confident will occur within a given quarter. The Company does not hedge its long-term exposure to commodity prices. Other than these very short-term forward contracts, the Company has not used derivative financial instruments to manage the risks associated with its operations and therefore, in the normal course of business, it is inherently exposed to currency, interest rate and commodity price fluctuations.

The Company owns equity interests in certain junior mining companies as long-term investments and therefore is inherently exposed to various risk factors including currency risk, market price risk and liquidity risk.

SILVER WHEATON ANNUAL REPORT [24]

Future Changes in Accounting Policies

INTERNATIONAL FINANCIAL REPORTING STANDARDS (“IFRS”)

Publicly listed companies will be required to adopt IFRS for interim and annual financial statements relating to fiscal years beginning on or after January 1, 2011. Silver Wheaton’s first consolidated financial statements presented in accordance with IFRS will be for the three month period ended March 31, 2011, which will include presentation of its comparative results for fiscal 2010 under IFRS.

In order to prepare for the changeover to IFRS, the Company has developed an IFRS conversion plan comprised of three phases:


Phase	Description and Status

Preliminary Planning and Scoping	This phase, which has been completed, involves development of the IFRS conversion plan.

	The IFRS conversion plan includes consideration of the impacts of IFRS on the Company’s consolidated financial statements, internal controls over financial reporting, information systems and business activities such as foreign operations, compensation metrics, personnel and training requirements and calculation of debt covenants. Based on management’s review of IFRS and current Company processes, the adoption of IFRS is expected to have minimal impact on information systems, operations of foreign subsidiaries, debt covenants and compensation metrics.

	The Company has designed internal controls to facilitate its conversion to IFRS and has implemented controls relevant at this stage of the process. A training program has been developed for appropriate personnel and training activities have taken place as planned.


Detailed Impact Assessment	This phase, which has been completed, involves a detailed review of IFRS relevant to the Company and identification of all differences between existing Canadian GAAP and IFRS that are expected to result in accounting and/or disclosure differences in the Company’s consolidated financial statements, along with quantifying the impact on key line items. This phase includes identification, evaluation and selection of accounting policies necessary for the Company’s conversion to IFRS and evaluation of the impact on outstanding operational elements such as debt covenants and budgeting.


Implementation	During this phase, which is substantially completed, the changes required for conversion to IFRS will be embedded in the associated business, financial close and reporting processes. This will include finalization and approval of accounting policy changes, collection of financial information necessary to prepare IFRS compliant consolidated financial statements, implementation of additional internal controls, and preparation and approval of completed IFRS consolidated financial statements.

SILVER WHEATON ANNUAL REPORT [26]

The following represents a summary of the most significant identified differences between the Company’s current accounting policies in accordance with Canadian GAAP and IFRS as at December 31, 2010. This should not be regarded as a complete list of changes that will result from the transition to IFRS. Rather, it is intended to highlight those areas which management believes to be the most significant. In addition, changes to IFRS standards or changes to interpretations of existing IFRS standards could alter the information presented below.

FIRST-TIME ADOPTION OF IFRS

IFRS 1, First-Time Adoption of International Financial Reporting (“IFRS 1”), provides entities adopting IFRS for the first time with a number of optional exemptions and mandatory exceptions to the general requirement for full retrospective application of IFRS. During the third quarter of 2010, the Company finalized its choice of optional exemptions expected to be taken under IFRS, with the only exemption being related to Business Combinations (see below).

BUSINESS COMBINATIONS

Under IFRS 3, Business Combinations (“IFRS 3”), there are several differences when compared to current Canadian GAAP. The most significant of these changes to the Company are:

The fair value of equity securities issued by the acquirer is determined at the date of acquisition;
Consideration transferred does not include acquisition-related costs; and
Any change in the assessment of the recoverability of the acquirer’s deferred tax assets as a result of the business combination is recognized in profit or loss.

In accordance with IFRS 1, the Company will elect not to apply this standard on a retrospective basis and will apply this standard to any acquisitions completed on or after January 1, 2010.

ASSET IMPAIRMENT

Canadian GAAP generally uses a two-step approach to impairment testing: (i) comparing asset carrying values with undiscounted future cash flows to determine whether impairment exists; and (ii) measuring any impairment by comparing asset carrying values with fair values. Under International Accounting Standard 36, Impairment of Assets (“IAS 36”), a one-step approach for both testing for and measuring impairment is used, with asset carrying values compared directly with the higher of: (i) fair value less costs to sell; and (ii) value in use (which uses discounted future cash flows). This may potentially result in more write-downs where carrying values of assets were previously supported under Canadian GAAP on an undiscounted cash flow basis, but could not be supported on a discounted cash flow basis. However, the extent of any new write-downs may be partially offset by the requirement under IAS 36 to reverse any previous impairment losses where circumstances have changed such that the impairments have been reduced. Canadian GAAP prohibits reversal of previously recorded impairment losses.

LONG-TERM INVESTMENTS

In November 2009, the International Accounting Standards Board introduced IFRS 9, Financial Instruments (“IFRS 9”), which is part of a project to replace IAS 39, Financial Instruments: Recognition and Measurement. Adoption of IFRS 9 is required by January 1, 2013, with early adoption permitted. The Company intends to adopt IFRS 9 effective January 1, 2011, with retrospective application.

Under IFRS 9, the Company’s long-term investments must be recorded at fair market value, with all fair value changes being reflected in net earnings. However, as the Company’s long-term investments are strategic in nature and are not held for trading, the Company intends to make a one time, irrevocable election to present all fair value changes from the long-term investments in other comprehensive income (“OCI”). No amount recognized in OCI is ever reclassified to net earnings at a later date. Under current Canadian GAAP, fair value changes in the Company’s long-term investments are reflected in OCI unless there is an impairment which is deemed to be other-than-temporary, in which case the unrealized loss is reflected in net earnings. In December 2008, management concluded that the Company’s long-term investments were other-than-temporarily impaired, resulting in a $64 million loss being recorded in net earnings. This non-cash write down will be reallocated within shareholder’s equity from retained earnings to accumulated other comprehensive income when the Company prepares its consolidated financial statements in accordance with IFRS.

SILVER WHEATON ANNUAL REPORT [27]

SHARE PURCHASE WARRANTS

For Canadian GAAP purposes, share purchase warrants are classified and accounted for as equity in the Company’s consolidated financial statements. Under International Accounting Standard 32, Financial Instruments: Presentation (“IAS 32”), share purchase warrants with an exercise price denominated in a currency other than the Company’s functional currency are to be classified and accounted for as a financial liability which is then marked-to-market on a quarterly basis with the gain or loss being reflected in the Company’s statement of operations. This non-cash adjustment will have no effect on the Company’s cash flow or liquidity. The impact of this adjustment to shareholders’ equity is summarized below.

IFRS IMPACT ON SHAREHOLDERS’ EQUITY AS AT JANUARY 1, 2010

The following table summarizes the impact to shareholders’ equity of the significant differences identified at this time between Canadian GAAP and IFRS as at January 1, 2010:


(US dollars in thousands - unaudited)			Increase /
Standard	Description of Change		(decrease)
IAS 32	To record the mark-to market adjustment on the Company's share-purchase warrants with a strike price in CAD $	$	(208,318	)
IAS 32	To record the fair value increment on the exercise of the Company's share purchase warrants with a strike price in CAD $		166,626
IAS 32	To reclassify share purchase warrants with a strike price in CAD$		(10,275	)
			(51,967	)
Shareholders' equity - January 1, 2010 (per Canadian GAAP)			1,723,925
Shareholders' equity - January 1, 2010 (per IFRS, estimated)		$	1,671,958

Related Party Transactions

On February 14, 2008, Goldcorp sold its entire 48% interest in Silver Wheaton by way of a secondary offering. As a result, Goldcorp ceased to be a related party as of such date.

From January 1, 2008 to February 14, 2008, the Company purchased 0.7 million ounces of silver from a subsidiary of Goldcorp at an average price of $3.95 per ounce, for total consideration of approximately $2.8 million.

Subsequent Event

On March 3, 2011, the Company announced that its Board of Directors had approved an inaugural quarterly cash dividend of $0.03 per common share ($0.12 per common share, annually), with the initial dividend being distributed on or about March 31, 2011.

SILVER WHEATON ANNUAL REPORT [28]

Controls and Procedures

DISCLOSURE CONTROLS AND PROCEDURES

Silver Wheaton’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, has evaluated the design and effectiveness of Silver Wheaton’s disclosure controls and procedures, as defined in the rules of the U.S. Securities and Exchange Commission and Canadian Securities Administrators, as of December 31, 2010. Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that Silver Wheaton’s disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2010.

INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, are responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision of the Chief Financial Officer, the Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. The Company’s controls include policies and procedures that:

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of the Company’s management and directors; and,
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the annual financial statements or interim financial statements.

There have been no significant changes in the Company’s internal control over financial reporting during the year ended December 31, 2010.

The Company’s management, including its Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s internal control over financial reporting using the framework and criteria established in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management has concluded that the internal control over financial reporting were effective at the reasonable assurance level as of December 31, 2010.

LIMITATION OF CONTROLS AND PROCEDURES

The Company’s management, including its Chief Executive Officer and Chief Financial Officer, believe that any disclosure controls and procedures or internal control over financial reporting, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, they cannot provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by unauthorized override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Accordingly, because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

(“Primero”) will deliver to the Company a per annum amount equal to the first 3.5 million ounces of payable silver produced at San Dimas and 50% of any excess, plus the Company will receive an additional 1.5 million ounces of silver per annum to be delivered by Goldcorp. Beginning August 6, 2014, Primero will deliver to the Company a per annum amount equal to the first 6.0 million ounces of payable silver produced at San Dimas and 50% of any excess, for the life of the mine.
11.	The Company’s attributable tonnage at Lagunas Norte, Pierina and Veladero was estimated by assuming 2010 production levels for the remaining three years. This tonnage was pro-rated between Proven and Probable Mineral Reserves according to the ratio of the December 31, 2010 Proven and Probable Mineral Reserves as published by Barrick Gold Corporation (“Barrick”), applying average reserve grades.
12.	The Company’s Yauliyacu purchase agreement (March 2006) with Glencore International AG provides for the delivery of up to 4.75 million ounces of silver per year for 20 years. In the event that silver produced at Yauliyacu in any year totals less than 4.75 million ounces, the maximum amount to be sold to the Company in subsequent years will be increased to make up the shortfall, so long as production allows. Depending upon mine production levels, it is possible that these attributable Resources and Reserves may not be completely mined before the agreement expires.
13.	The Mineral Park and Rosemont Resources and Reserves do not include the SX/EW leach material since this process does not recover silver.
14.	Los Filos Resources and Reserves now include the Bermejal deposit.
15.	The Company has filed a technical report for each of its mineral projects considered to be material to the Company, being San Dimas, Yauliyacu, Peñasquito and Pascua-Lama, which are available on SEDAR at www.sedar.com.
16.	Silver is produced as a by-product metal at all operations with the exception of the Keno Hill mine and Loma de La Plata project; therefore, the economic cut-off applied to the reporting of silver Resources and Reserves will be influenced by changes in the commodity prices of other metals at the time.

Cautionary Note Regarding Forward-Looking Statements

The information contained herein contains “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 and “forward-looking information” within the meaning of applicable Canadian securities legislation. Forward-looking statements, which are all statements other than statements of historical fact, include, but are not limited to, statements with respect to the future price of silver or gold, the estimation of mineral reserves and resources, the realization of mineral reserve estimates, the timing and amount of estimated future production, costs of production, reserve determination and reserve conversion rates. Generally, these forward-looking statements can be identified by the use of forward-looking terminology such as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “does not anticipate”, or “believes”, or variations of such words and phrases or statements that certain actions, events or results “may”, “could”, “would”, “might” or “will be taken”, “occur” or “be achieved”. Forward-looking statements are subject to known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, performance or achievements of Silver Wheaton to be materially different from those expressed or implied by such forward-looking statements, including but not limited to: fluctuations in the price of silver or gold; the absence of control over mining operations from which Silver Wheaton purchases silver and gold and risks related to these mining operations including risks related to fluctuations in the price of the primary commodities mined at such operations, actual results of mining and exploration activities, economic and political risks of the jurisdictions in which the mining operations are located and changes in project parameters as plans continue to be refined; and differences in the interpretation or application of tax laws and regulations; as well as those factors discussed in the section entitled “Description of the Business - Risk Factors” in Silver Wheaton's Annual Information Form available on SEDAR at www.sedar.com and in Silver Wheaton's Form 40-F on file with the U.S. Securities and Exchange Commission in Washington, D.C. Forward-looking statements are based on assumptions management believes to be reasonable, including but not limited to: the continued operation of the mining operations from which Silver Wheaton purchases silver and gold, no material adverse change in the market price of commodities, that the mining operations will operate and the mining projects will be completed in accordance with their public statements and achieve their stated production outcomes, and such other assumptions and factors as set out herein. Although Silver Wheaton has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate. Accordingly, readers should not place undue reliance on forward-looking statements. Silver Wheaton does not undertake to update any forward-looking statements that are included or incorporated by reference herein, except in accordance with applicable securities laws.

Cautionary Language Regarding Reserves And Resources

For further information on Mineral Reserves and Mineral Resources and on Silver Wheaton more generally, readers should refer to Silver Wheaton’s Annual Information Form for the year ended December 31, 2010 and other continuous disclosure documents filed by Silver Wheaton since January 1, 2011, available on SEDAR at www.sedar.com. Silver Wheaton’s Mineral Reserves and Mineral Resources are subject to the qualifications and notes set forth therein. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources: The information contained herein uses the terms “Measured”, “Indicated” and “Inferred” Mineral Resources. United States investors are advised that while such terms are recognized and required by Canadian regulations, the United States Securities and Exchange Commission does not recognize them and expressly prohibits U.S. registered companies from including such terms in their filings with the SEC. “Inferred Mineral Resources” have a great amount of uncertainty as to their existence, and as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. United States investors are cautioned not to assume that all or any part of Measured or Indicated Mineral Resources will ever be converted into Mineral Reserves. United States investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists, or is economically or legally mineable. United States investors are urged to consider closely the disclosure in Silver Wheaton’s Form 40-F, a copy of which may be obtained from Silver Wheaton or from http://www.sec.gov/edgar.shtml.

Management’s Responsibility for Financial Reporting

The accompanying consolidated financial statements of Silver Wheaton Corp. (“Silver Wheaton”) were prepared by management, which is responsible for the integrity and fairness of the information presented, including the many amounts that must of necessity be based on estimates and judgments.

Financial information appearing throughout our management’s discussion and analysis is consistent with these consolidated financial statements.

In discharging our responsibility for the integrity and fairness of the consolidated financial statements and for the accounting systems from which they are derived, we maintain and rely on a comprehensive system of internal controls designed to ensure that transactions are authorized, assets are safeguarded and proper records are maintained. These controls include business planning; delegation of authority; careful selection and hiring of staff; accountability for performance within appropriate and well-defined areas of responsibility; and the communication of policies and guidelines of business conduct throughout the company.

The Board of Directors oversees management’s responsibilities for financial reporting through the Audit Committee, which is composed entirely of directors who are neither officers nor employees of Silver Wheaton. The Audit Committee reviews Silver Wheaton’s interim and annual consolidated Financial Statements and Management‘s Discussion and Analysis (MD&A) and recommends them for approval by the Board of Directors. Other key responsibilities of the Audit Committee include monitoring Silver Wheaton’s system of internal controls, monitoring its compliance with legal and regulatory requirements, selecting the external auditors and reviewing the qualifications, independence and performance of the external auditors.

Deloitte & Touche LLP, Independent Registered Chartered Accountants appointed by the shareholders of Silver Wheaton upon the recommendation of the Audit Committee and Board, have performed an independent audit of the consolidated financial statements and their report follows.

SILVER WHEATON ANNUAL REPORT [36]

Report of Independent Registered Chartered Accountants

To the Board of Directors and Shareholders of Silver Wheaton Corp.

We have audited the accompanying consolidated balance sheets of Silver Wheaton Corp. and its subsidiaries (the “Company”) as of December 31, 2010 and 2009, and the related consolidated statements of operations, comprehensive income (loss), cash flows, and shareholders’ equity for each of the three years in the period ended December 31, 2010. These financial statements are the responsibility of the Company'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 our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Silver Wheaton Corp. and its subsidiaries as of December 31, 2010 and 2009 and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2010 in conformity with Canadian generally accepted accounting principles.

On March 23, 2011, we reported separately to the Board of Directors and Shareholders of Silver Wheaton Corp. that we have also audited, in accordance with Canadian generally accepted auditing standards, consolidated financial statements for the same periods, prepared in accordance with Canadian generally accepted accounting principles but which excluded the footnote providing a reconciliation of accounting principles generally accepted in Canada and the United States of America as it related to the Company.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 23, 2011 expressed an unqualified opinion on the Company’s internal control over financial reporting.

SILVER WHEATON ANNUAL REPORT [37]

Management’s Report on Internal Control Over Financial Reporting

Management of Silver Wheaton Corp. (“Silver Wheaton”) is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed by, or under the supervision of the Chief Executive Officer and the Chief Financial Officer and effected by the Board of Directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. It includes those policies and procedures that:

	I.	pertain to the maintenance of records that accurately and fairly reflect, in reasonable detail, the transactions related to Silver Wheaton’s assets

	II.	provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and Silver Wheaton receipts and expenditures are made only in accordance with authorizations of management and Silver Wheaton’s directors

	III.	provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of Silver Wheaton assets that could have a material effect on Silver Wheaton’s financial statements.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements on a timely basis. Also, projections of any evaluation of the effectiveness of internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of Silver Wheaton’s internal control over financial reporting as of December 31, 2010, based on the criteria set forth in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management has concluded that, as of December 31, 2010, Silver Wheaton’s internal control over financial reporting was effective.

The effectiveness of Silver Wheaton’s internal control over financial reporting, as of December 31, 2010, has been audited by Deloitte & Touche LLP, Independent Registered Chartered Accountants, as stated in their report which appears on the following page.

SILVER WHEATON ANNUAL REPORT [38]

Report of Independent Registered Chartered Accountants

To the Board of Directors and Shareholders of Silver Wheaton Corp.

We have audited the internal control over financial reporting of Silver Wheaton Corp. and its subsidiaries (the “Company”) as of December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with Canadian generally accepted auditing standards and in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2010 of the Company and our report dated March 23, 2011 expressed an unqualified opinion on those financial statements.

SILVER WHEATON ANNUAL REPORT [43]


1.	Description of Business and Nature of Operations


2.	Summary of Significant Accounting Policies

BASIS OF PRESENTATION

These consolidated financial statements have been prepared in accordance with Canadian generally accepted accounting principles (“Canadian GAAP” or “GAAP”). A reconciliation of Canadian GAAP to accounting principles generally accepted in the United States (“US GAAP”) is provided in Note 14.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and its 100% owned subsidiaries Silver Wheaton (Caymans) Ltd. (“SW Caymans”) and Silverstone Resources (Barbados) Corp. (“SST Barbados”).

USE OF ESTIMATES

The preparation of financial statements in conformity with Canadian GAAP requires management to make estimates that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant areas where management’s judgment is applied are the valuation of silver and precious metal purchase agreements, depletion, stock based compensation, the valuation of share purchase warrants held and income taxes. Actual results could differ from those reported.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash, and those short-term money market instruments that are readily convertible to cash with an original term to maturity of less than 90 days.

SILVER INVENTORY

Silver inventory is valued at the lower of average cost and net realizable value.

LONG-TERM INVESTMENTS

Long-term investments in equity securities are classified as available-for-sale because the Company intends to hold the investments for more than one year. Unrealized holding gains and losses related to available-for-sale investments are excluded from net earnings and are included in other comprehensive income (“OCI”) until such gains or losses are realized or an other-than-temporary impairment is determined to have occurred.

Warrants held by the Company are for long-term investment purposes, however, due to their nature they meet the definition of a derivative and are marked-to-market on a quarterly basis. Mark-to-market gains and losses relating to the warrants are included in net earnings in the period they occur.

SILVER WHEATON ANNUAL REPORT [44]

SILVER AND GOLD INTERESTS

Agreements for which settlement is called for in silver and gold, the amount of which is based on production at the mines, are recorded at cost. The cost of these assets is separately allocated to reserves, resources and exploration potential. The value allocated to reserves is classified as depletable and is depleted on a unit-of-sale basis over the estimated recoverable proven and probable reserves at the mine corresponding to the specific agreement. The value associated with resources and exploration potential is the value beyond proven and probable reserves at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category as a result of the conversion of resources or exploration potential into reserves.

Evaluations of the carrying values of each agreement are undertaken each year to determine if estimated undiscounted future net cash flows are less than the carrying value. Estimated undiscounted future net cash flows are calculated using estimated production, sales prices and purchase costs. If it is determined that the future net cash flows from an operation are less than the carrying value then a write-down is recorded with a charge to operations.

INTEREST AND DEBT ISSUE COSTS

Interest costs allocable to the acquisition or construction of qualifying assets, which are assets that necessarily take a substantial period of preparation for their intended use or sale, are capitalized and included in the carrying amounts of the related assets until such time as the assets are substantially ready for their intended use or sale.

Debt issue costs are expensed when they are incurred, unless they are directly attributable to the acquisition or construction of qualifying assets in which case they are added to the cost of those assets until such time as the assets are substantially ready for their intended use or sale.

REVENUE RECOGNITION

SILVER WHEATON ANNUAL REPORT [45]

STOCK BASED COMPENSATION

The fair value of all stock based awards granted is estimated using the Black-Scholes model. The compensation cost related to stock options granted is recorded in the consolidated statements of operations.

INCOME TAXES

The future income tax asset and liability method of accounting for income taxes is used. As the majority of the Company’s operating profit is derived from its subsidiaries, SW Caymans and SST Barbados, which are incorporated and operated in the Cayman Islands and Barbados, respectively, the Company’s profits are subject to minimal income tax. Management views the subsidiaries’ profits as part of its permanent investment in the subsidiaries, and it has determined that those profits will be reinvested in foreign jurisdictions for the foreseeable future, therefore, the Company has not provided for future income taxes on the undistributed earnings of its foreign subsidiaries.

EARNINGS PER SHARE

Earnings per share calculations are based on the weighted average number of common shares and common share equivalents issued and outstanding during the year. Diluted earnings per share is calculated using the treasury method which requires the calculation of diluted earnings per share by assuming that outstanding share purchase options and warrants, with an average market price that exceeds the average exercise prices of the options and warrants for the year, are exercised and the proceeds are used to repurchase shares of the Company at the average market price of the common shares for the year.

FOREIGN CURRENCY TRANSLATION

Foreign currency monetary assets and liabilities are translated into United States dollars at the exchange rates prevailing at the balance sheet date. Non-monetary assets denominated in foreign currencies are translated using the rate of exchange at the transaction date. Foreign currency transactions are translated at the United States dollar rate prevailing on the transaction dates. Foreign exchange gains and losses are included in the determination of earnings except for the foreign exchange gains and losses on the Company’s available-for-sale investments which are included in the determination of comprehensive income until such gains or losses are realized or an other-than-temporary impairment is determined to have occurred.

3.	Fair Values of Financial Instruments

The Company thoroughly examines the various financial instrument risks to which it is exposed and assesses the impact and likelihood of those risks. These risks may include credit risk, liquidity risk, currency risk, interest rate risk and other price risks. Where material, these risks are reviewed and monitored by the Board of Directors.

CAPITAL RISK MANAGEMENT

The Company manages its capital to ensure that it will be able to continue as a going concern while maximizing the return to stakeholders through the optimization of the debt and equity balance.

The capital structure of the Company consists of debt (Note 6) and equity attributable to common shareholders, comprising of issued capital, contributed surplus, retained earnings and accumulated other comprehensive income.

The Company is in compliance with the debt covenants described in Note 6.

SILVER WHEATON ANNUAL REPORT [46]

CREDIT RISK

The Company is exposed to various counterparty risks and liquidity risks including, but not limited to: (i) through the companies with which the Company has purchase agreements; (ii) through financial institutions that hold the Company’s cash and cash equivalents; (iii) through companies that have payables to the Company, including concentrate customers; (iv) through the Company’s insurance providers; and (v) through the Company’s lenders. The Company invests surplus cash in short-term, high credit quality, money market instruments. In addition, the Company's insurance providers, lenders and the counterparties used to sell silver and gold are all large international organizations with strong credit ratings and the balance of trade receivables owed to the Company in the ordinary course of business is not significant. Therefore, the Company is not exposed to significant credit risk and overall, the Company’s credit risk has not changed significantly from the prior year.

LIQUIDITY RISK

The Company has in place a rigorous planning and budgeting process to help determine the funds required to support the Company’s normal operating requirements on an ongoing basis and its expansionary plans. The Company ensures that there are sufficient committed loan facilities to meet its short-term business requirements, taking into account its anticipated cash flows from operations and its holdings of cash and cash equivalents. As at December 31, 2010, the Company had cash and cash equivalents of $428.6 million and working capital of $265.1 million. The Company invests surplus cash in short-term, high credit quality, money market instruments. Of the Company’s $400 million Revolving Loan, up to $10 million can be drawn at any time to cover general operational costs, while the remainder can be drawn for the acquisition of silver interests and investments.

Silver Wheaton holds shares and warrants of other exploration and mining companies with a combined market value at December 31, 2010 of $284.4 million (December 31, 2009 - $73.7 million). The daily exchange traded volume of these shares, including the shares underlying the warrants, is not sufficient for the Company to liquidate its position in a short period of time without potentially affecting the market value of the shares. These shares and warrants are held for strategic purposes and are considered long-term investments and therefore as part of the Company’s planning, budgeting and liquidity analysis process these investments are not relied upon to provide operational liquidity.

CURRENCY RISK

Financial instruments that impact the Company’s net earnings or other comprehensive income due to currency fluctuations include: cash and cash equivalents, accounts receivable, long-term investments, accounts payable and accrued liabilities denominated in Canadian dollars. The sensitivity of the Company’s net earnings and other comprehensive income due to changes in the exchange rate between the Canadian dollar and the United States dollar is summarized in the table below:


		As at December 31, 2010
(in thousands)		10% Increase in the Canadian Dollar		10% Decrease in the Canadian Dollar

Increase (decrease) in net earnings	$	4,409	$	(4,409	)
Increase (decrease) in other comprehensive income		27,875		(27,875	)
Comprehensive income (loss)	$	32,284	$	(32,284	)

SILVER WHEATON ANNUAL REPORT [47]

INTEREST RATE RISK

The Company is exposed to interest rate risk on its outstanding borrowings and short-term investments. Presently, all of the Company’s outstanding borrowings are at floating interest rates and all of its interest-bearing investments have terms of less than 90 days. The Company monitors its exposure to interest rates and has not entered into any derivative contracts to manage this risk. The weighted average interest rate paid by the Company during the year on its outstanding borrowings was 1.16%.

For the year ended December 31, 2010, all of the interest incurred by the Company has been capitalized as it relates to the acquisition of the Peñasquito, Keno Hill and Barrick silver interests, which were all under development during the year. As a result, changes in interest rates will not materially affect the Company’s net earnings or other comprehensive income until such time as all of these projects are brought into commercial production. A fluctuation in interest rates of 100 basis points (1 percent) would have impacted the amount of interest capitalized during the year by approximately $1.2 million.

OTHER PRICE RISKS

The Company is exposed to equity price risk as a result of holding long-term investments in other exploration and mining companies. The Company does not actively trade these investments.

The sensitivity analysis below has been determined based on the exposure to equity price risks at December 31, 2010.

If equity prices had been 10% higher or lower:

net earnings for the year would have increased/decreased by approximately $0.6 million; and
other comprehensive income would have increased/decreased by approximately $27.9 million as a result of changes in the fair value of available-for-sale securities.

FAIR VALUE ESTIMATION

For fair value estimates relating to derivatives, available-for-sale securities and warrants, the Company classifies its fair value measurements within a fair value hierarchy, which reflects the significance of the inputs used in making the measurements as defined in CICA Handbook Section 3862.


Level 1 -	Unadjusted quoted prices at the measurement date for identical assets or liabilities in active markets.

Level 2 -	Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 -	Unobservable inputs which are supported by little or no market activity.

SILVER WHEATON ANNUAL REPORT [48]

The following table sets forth the Company’s financial assets and liabilities measured at fair value by level within the fair value hierarchy. As required by Section 3862, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.


				December 31, 2010

(in thousands)		Total		Quoted prices in active markets for identical assets (Level 1)		Significant other observable inputs (Level 2)		Unobservable inputs (Level 3)

Cash and cash equivalents	$	428,636	$	428,636	$	-	$	-
Trade receivable from provisional concentrate sales, net		4,650		-		4,650		-

Warrants		5,700		-		5,700		-

Total	$	717,734	$	707,384	$	10,350	$	-

The Company’s trade receivables from provisional concentrate sales are valued based on forward prices of silver and gold until the date of final settlement. As such, these receivables are classified within Level 2 of the fair value hierarchy.

The Company’s available-for-sale securities are valued using quoted market prices in active markets and as such, are classified within Level 1 of the fair value hierarchy. The fair value of the investment securities is calculated as the quoted market price of the investment equity security multiplied by the quantity of shares held by the Company.

The fair value of warrants that are not traded in an active market is determined using a Black-Scholes model based on assumptions that are supported by observable current market conditions and as such are classified within Level 2 of the fair value hierarchy. The use of reasonably possible alternative assumptions would not significantly affect the Company’s results.

Trade receivables and payables are non-interest bearing and are stated at carrying values, which approximate fair values due to the short terms to maturity. Where necessary, trade receivables are net of allowances for uncollectable amounts.

The Company’s bank debt (Note 6) and the silver interest payments due (Note 7) are classified as held-to-maturity and reported at amortized cost using the effective interest method.


4.	Long-Term Investments


(in thousands)		December 31, 2010		December 31, 2009

Available-for-sale	$	278,748	$	72,502
Warrants		5,700		1,245
	$	284,448	$	73,747

SILVER WHEATON ANNUAL REPORT [49]

Unrealized holding gains and losses related to available-for-sale investments are excluded from net earnings and are included in other comprehensive income until such gains or losses are either: (i) realized or (ii) an other-than-temporary impairment is determined to have occurred.

During 2010, the Company acquired, by way of private placement, 3.0 million common shares of Bear Creek Mining Corporation (“Bear Creek”) at a price of Cdn$6.40 per share, for total consideration of Cdn$19.1 million. As a result, at December 31, 2010, Silver Wheaton owned 13.3 million common shares of Bear Creek representing approximately 14% of the outstanding shares of Bear Creek. At December 31, 2010, the fair value of the Company’s investment in Bear Creek was $126.7 million.

At December 31, 2010, Silver Wheaton owned common shares and common share purchase warrants of several publicly traded mineral exploration, development and mining companies. As Silver Wheaton’s investment represents less than 10% of the outstanding shares of each of the respective companies, these investments have been reflected in these financial statements as part of Other long-term investments. At December 31, 2010, the fair value of the Other long-term investments was $121.8 million.

Warrants acquired as part of private placements have been valued using a Black-Scholes option pricing model.

By holding these long-term investments, the Company is inherently exposed to various risk factors including currency risk, market price risk and liquidity risk (Note 3).

SILVER WHEATON ANNUAL REPORT [52]

The value allocated to reserves is classified as depletable upon a mining operation achieving commercial production and is depleted on a units-of-sale basis over the estimated recoverable proven and probable reserves at the mine. The value associated with resources and exploration potential is allocated at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category, generally as a result of the conversion of resources or exploration potential into reserves.

The following represents a summary of the significant changes to silver and gold interests which occurred during the year:

SAN DIMAS

On October 15, 2004, the Company entered into an agreement (amended on March 30, 2006) with Goldcorp Inc. (“Goldcorp”) to acquire an amount equal to 100% of the silver produced by Goldcorp’s Luismin mining operations in Mexico (owned at the date of the transaction) for a period of 25 years. The Luismin operations consisted primarily of the San Dimas and Los Filos mines.

On August 6, 2010, Goldcorp completed the sale of the San Dimas mine to Primero Mining Corp. (“Primero”). In conjunction with the sale, Silver Wheaton amended its silver purchase agreement relating to the mine. The term of the agreement, as it relates to San Dimas, was extended to the life of mine. During the first four years following closing of the transaction, Primero will deliver to Silver Wheaton a per annum amount equal to the first 3.5 million ounces of payable silver produced at San Dimas and 50% of any excess, plus Silver Wheaton will receive an additional 1.5 million ounces of silver per annum to be delivered by Goldcorp. Beginning in the fifth year after closing, Primero will deliver to the Company a per annum amount equal to the first 6 million ounces of payable silver produced at San Dimas and 50% of any excess. Goldcorp will continue to guarantee the delivery by Primero of all silver produced and owing to the Company until 2029. Primero has provided Silver Wheaton with a right of first refusal on any metal stream or similar transaction it enters into.

SILVER WHEATON ANNUAL REPORT [53]

ROSEMONT

On February 11, 2010, the Company entered into an agreement with Augusta Resource Corporation (“Augusta”) to acquire an amount equal to 100% of the life of mine silver and gold production from its Rosemont Copper project (“Rosemont”) in the United States. The Company will make total upfront cash payments of $230 million payable in installments to partially fund construction of the mine commencing once certain milestones are achieved, including the receipt of key permits and securing the necessary financing to complete construction of Rosemont. In addition, a cash payment of the lesser of $3.90 per ounce of silver and $450 per ounce of gold (both subject to an inflationary adjustment) or the prevailing market price is due, for silver and gold delivered under the agreement. Augusta anticipates that key operating permits will be received in 2011 and has provided a completion guarantee with certain minimum production criteria required to be met by specific dates.

LOMA DE LA PLATA

On February 25, 2010, the Company elected to convert the debenture with Pan American Silver Corp. ("Pan American") into an agreement to acquire an amount equal to 12.5% of the life of mine silver production from the Loma de La Plata zone of the Navidad project located in Argentina. Silver Wheaton will make total upfront cash payments of $32.4 million following the satisfaction of certain conditions, including Pan American receiving all necessary permits to proceed with the mine construction. In addition, a cash payment of $4.00 per ounce is due for silver delivered under the agreement. The definitive terms of the agreement are in the process of being finalized.

LA NEGRA

6.	Bank Debt

The Company has a $200 million non-revolving term loan (the “Term Loan”) and a $400 million revolving term loan (the “Revolving Loan”). The current term of the Revolving Loan and the Term Loan matures on July 20, 2014 with the Term Loan requiring equal quarterly principal repayments of approximately $7 million (together with accrued interest). Silver Wheaton has committed to pay down the Revolving Loan, within 61 days after the end of each fiscal quarter, by an amount equal to 90% of the increase in cash balances reported for the quarter. The Revolving Loan can be drawn down at any time to finance acquisitions or investments, with $10 million being available for general corporate purposes.

Amounts drawn incur interest at LIBOR plus 0.875% to 1.75% per annum dependent upon the Company’s leverage ratio. Undrawn amounts are subject to a commitment fee of 0.2% to 0.45% per annum, dependent on the Company’s leverage ratio. Under the credit agreement, the Company is required to maintain a debt service coverage ratio greater than or equal to 1.25:1, a leverage ratio less than or equal to 3.5:1, and a tangible net worth greater than 80% of the tangible net worth at June 30, 2007 plus 50% of net earnings for each fiscal quarter thereafter. Both the Term Loan and the Revolving Loan are secured against the Company’s assets, including the Company’s silver and gold interests and long-term investments.

During 2010, the Company repaid $28.6 million of the balance outstanding on the Term Loan. As at December 31, 2010, the Company had $400 million available under its revolving debt facility.

The Company is in compliance with the debt covenants described above.

SILVER WHEATON ANNUAL REPORT [54]

7.	Silver Interest Payments

On October 2, 2008, the Company entered into an agreement with Alexco Resource Corp. (“Alexco”) to acquire an amount equal to 25% of the silver produced from Alexco’s Keno Hill project located in Canada, for the life of mine. Silver Wheaton will make total upfront cash payments of $50 million payable in installments, of which $47.5 million has been paid to date. The remaining $2.5 million was paid during the first quarter of 2011.

On September 8, 2009, the Company entered into an agreement with Barrick Gold Corporation (“Barrick”) to acquire an amount equal to 25% of the life of mine silver production from its Pascua-Lama project, as well as 100% of the silver production from its Lagunas Norte, Pierina and Veladero mines until the end of 2013. Silver Wheaton will make total upfront cash payments of $625 million payable in installments, of which $350 million has been paid to date. The remaining $275 million is payable in annual installments of $137.5 million due on the second and third anniversaries of the transaction. The financial liability relating to these future payments has been discounted using an annual discount rate of 6.9%, which represents management’s best estimate of the market rate of interest at which the Company could borrow money under similar terms and conditions at the time the agreement was entered into. The silver interest payments due are classified as held-to-maturity and reported at amortized cost using the effective interest method. Total interest costs of $51 million will accrete over the term of this obligation and will be capitalized to the cost of the Barrick silver interest, until the Pascua-Lama mining operation is commissioned. To date, $29.1 million of the interest costs have been accreted to the cost of the Barrick silver interest, of which $23.1 million was capitalized during the year ended December 31, 2010. Management estimates that the market rate of interest on a similar borrowing has decreased to approximately 3.2% per annum as at December 31, 2010. Accordingly, at December 31, 2010, the fair value of the silver interest payments due to Barrick has increased to approximately $264 million, compared to a carrying amount of $253 million.

During 2008, the Company issued approximately 27.5 million common shares in connection with the early exercise of the share purchase warrants and the series “A” warrants, as described in Note 8(d).

On February 12, 2009, the Company announced that it had closed a bought deal equity financing, raising gross proceeds of Cdn$287.5 million ($230.4 million) through the issuance of 35,937,500 common shares at Cdn$8.00 per share (approximately $6.41 per share). The proceeds were primarily used to repay outstanding debt under the revolving bank loan facility.

On May 21, 2009, the Company closed the acquisition of Silverstone Resources Corp. (“Silverstone”) through the issuance of 23,434,332 common shares and 1,367,364 share purchase options of Silver Wheaton which were issued on conversion of previously issued fully vested share purchase options of Silverstone. Including acquisition costs, the transaction was valued at approximately $152 million.

On September 30, 2009, in conjunction with the Barrick acquisition, the Company closed a bought deal equity financing, raising gross proceeds of $287.5 million through the issuance of 25,903,750 common shares at $11.10 per share, with part of the net proceeds being used to finance the initial upfront payment of $212.5 million made to Barrick. The remaining net proceeds from the equity financing are available for general corporate purposes including funding the acquisition of future silver interests.

During 2009, the Company received gross proceeds in excess of $13.8 million from the exercise of the share purchase warrants and Series “A” warrants which expired on August 5, 2009 and November 30, 2009, respectively, resulting in the issuance of 3,455,636 common shares.

During 2010, the Company received gross proceeds in excess of $76.1 million, primarily from the exercise of the Series “B” warrants which expired on December 22, 2010, resulting in the issuance of 7,738,030 common shares.

SILVER WHEATON ANNUAL REPORT [57]

b) Share Purchase Options

The Company has established a share purchase option plan whereby the Company’s Board of Directors may, from time to time, grant options to employees or consultants. The maximum term of any option may be ten years, but generally options are granted for five years. The exercise price of an option is not less than the closing price on the TSX on the last trading day preceding the grant date. Vesting of options is at the discretion of the Company’s Board of Directors at the time the options are granted, but generally vest over a period of two years.

Stock based compensation expense during 2010 included $6.0 million of amortization of the fair value of share purchase options issued, compared to $3.6 million during 2009.

During 2010, the Company issued 1,288,700 options with a weighted average exercise price of Cdn$15.89 per option with a fair value of $6.9 million or Cdn$5.54 per option, which was determined using the Black-Scholes option value method. During 2009, the Company issued 1,137,000 options with a weighted average exercise price of Cdn$9.09 per option and a fair value of $2.6 million or Cdn$2.90 per option, also determined using the Black-Scholes option value method. The following weighted average assumptions were used in computing the fair value of stock options:

e) Diluted Earnings Per Share

Diluted earnings per share is calculated using the treasury method which requires the calculation of diluted earnings per share by assuming that outstanding share purchase options and warrants, with exercise prices that are lower than the average market price for the relevant period, are exercised and the proceeds are used to repurchase shares of the Company at the average market price of the common shares for the relevant period.

Diluted earnings per share is calculated based on the following weighted average number of shares outstanding:


	Years Ended December 31
(in thousands)		2010	2009	2008

Basic weighted average number of shares outstanding		344,288	306,040	232,855

Share purchase options		1,703	1,095	887
Share purchase warrants		4,261	2,279	15,442
Restricted share units		177	86	60
Diluted weighted average number of shares outstanding		350,429	309,500	249,244

The following lists the share purchase options and share purchase warrants excluded from the computation of diluted earnings per share because the exercise prices exceeded the average market value of the common shares of Cdn$22.86, compared to Cdn$11.33 and Cdn$12.16 for the comparable periods in 2009 and 2008, respectively.

SILVER WHEATON ANNUAL REPORT [69]

a) Share Purchase Warrants

For Canadian GAAP purposes, share purchase warrants are classified and accounted for as equity in the Company’s consolidated financial statements. In 2006, a technical interpretation of US GAAP, in accordance with ASC 815-40, Contracts in Entity's Own Equity, requires share purchase warrants with an exercise price denominated in a currency other than the Company’s functional currency be classified and accounted for as a financial liability. This non-cash adjustment has no effect on the Company’s cash flow or liquidity.

b) Induced Conversion of Common Share Purchase Warrants

For Canadian GAAP purposes, the fair market value of the “New Warrants” which were issued as an incentive to the series “A” warrant holders (Note 8d) to exercise their existing warrants during an early exercise period (Note 8d) was treated as a reduction to shareholders equity. For US GAAP purposes, the series “A” share purchase warrants were classified and accounted for as a financial liability when issued. Accordingly, the fair market value of the “New Warrants” which were issued as an incentive to induce conversion of these warrants was recognized as an expense.

c) Accounting for Silverstone Acquisition

On May 21, 2009, the Company completed the acquisition of Silverstone. There are a number of differences in accounting for the transaction between Canadian GAAP and US GAAP.

On January 1, 2009, the Company adopted ASC 805 - Business Combinations (“ASC 805”). Under this new standard, business combinations are accounted for under the "acquisition method," compared to the "purchase method". The standard also presents revised guidance for a number of areas, including (i) the definition of a business for the purpose of acquisitions; (ii) the measurement date for equity interests issued by the acquirer; (iii) the adjustment of income tax estimates in the acquisition; (iv) the treatment of acquisition-related costs of the acquirer; (v) the disclosure requirements around the nature and financial effects of the business combination; and (vi) the measurement of assets acquired, liabilities assumed, and non-controlling interest in an acquisition of less than 100% of the acquiree.

The Company has identified the following GAAP differences:

For Canadian GAAP purposes, the value of the common shares issued in connection with the Silverstone Acquisition were measured based on the trade weighted average price of Silver Wheaton common shares on the Toronto Stock Exchange (“TSX”) for the 2 days prior to, the day of and two days after March 12, 2009, the day of announcement of the Agreement, resulting in a total valuation of $146.2 million. For US GAAP purposes, the value of the common shares have been measured based on the closing price of Silver Wheaton common shares on the TSX on May 21, 2009, being the date the Silverstone Acquisition closed, resulting in an increase in value of $73.1 million.
For Canadian GAAP purposes, the value of the share purchase options issued in connection with the Silverstone Acquisition were measured using the Black-Scholes option value method with a weighted average exercise price of Cdn$8.02 per option, calculated based on the trade weighted average price of Silver Wheaton common shares on the TSX for the 2 days prior to, the day of and two days after March 12, 2009, the day of announcement of the Agreement, resulting in a total valuation of $2.6 million. For US GAAP purposes, the value of the share purchase options issued have been measured using a weighted average exercise price of Cdn$10.80 per option based on the closing price of Silver Wheaton common shares on the TSX on May 20, 2009, being the date prior to the Silverstone Acquisition closing, resulting in an increase in value of $2.6 million.
For Canadian GAAP purposes, acquisition-related costs of the Company totaling $3.3 million have been capitalized as part of the cost of the business combination. For US GAAP purposes, these costs were expensed on acquisition.
For Canadian GAAP purposes, the Company was able to record previously unrecognized non-capital losses as future income tax assets (“FITA’s”) in its Silverstone purchase price allocation. For US GAAP purposes, the Company was unable to recognize these losses as FITA’s on the acquisition of Silverstone. However, the Company was able to record these FITA’s subsequent to the acquisition of Silverstone which increases the future income tax recovery by $4.5 million in 2009 for US GAAP purposes.

SILVER WHEATON ANNUAL REPORT [70]

As a result of the increase in value of the consideration paid for US GAAP purposes and the other adjustments as noted above, the Company recorded an additional $65.9 million in value attributable to the silver and gold interests acquired and goodwill of $11 million. For the year ended December 31, 2010, the Company recorded additional depletion on its silver and gold interests of $8.0 million, resulting in cumulative additional depletion on its silver and gold interests of $13.2 million.

d) Future Income Taxes

As more fully described in Note 4, the Company’s future income tax expense or recovery in a given period is largely determined by changes in the unrealized gains or losses recorded with respect to its long-term investments. As a result of a significant increase in the value of the long-term investments during 2010, the Company recorded a future income tax liability with the associated $14.4 million future income tax expense being reflected as a component of other comprehensive income. The Company has future tax assets relating to tax losses and tax deductions which had not been previously recognized. For Canadian GAAP purposes, the Company has reversed its valuation allowance and recognized these future income tax assets, which partially offset this future tax liability, with the resulting $13.6 million future income tax recovery being reflected in net earnings. For US GAAP purposes, this future tax benefit is to be reported in the same manner as the source of the income in the current year, and as a result has been reported as a component of other comprehensive income. The 2008 future tax expense of $2.9 million has been reclassified to conform with this accounting treatment.

e) Stock Options

The total intrinsic value of stock options outstanding and exercisable at December 31, 2010, was $65.6 million and $35.1 million, respectively. The total intrinsic value of stock options exercised during the year ended December 31, 2010 was $74.1 million.

At December 31, 2010, there was $1.8 million of total unrecognized compensation costs related to unvested stock options. These costs will be recognized over the weighted average period of 6 months. The following table summarizes the changes in the Company’s unvested stock options during the year ended December 31, 2010:


	Number of Options Outstanding			Weighted Average Grant Date Fair Value (Cdn$/option)

Unvested stock options, as at January 1, 2010	1,311,650		$	3.15
Granted	1,288,700			5.38
Vested	(1,379,566	)		4.06
Forfeited	(8,333	)		2.32
Unvested stock options, as at December 31, 2010	1,212,451		$	4.49

f) Accounting for Uncertainty in Income Taxes

In July 2006, the FASB issued an interpretation of ASC 740 – Income Taxes (“ASC 740”) which addresses the accounting for uncertainty in income taxes. This interpretation provides guidance on the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 prescribes a recognition threshold and measurement of a tax position taken or expected to be taken in a tax return. This interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.

Effective January 1, 2007 the Company adopted ASC 740. The adoption did not result in any adjustment to opening retained earnings under US GAAP. As a result of the implementation of ASC 740, the Company did not recognize any liabilities for unrecognized tax benefits. In the event that the Company recognizes interest accrued related to unrecognized tax benefits, it will be recorded in interest expense. Any penalties will be recorded in general and administrative expense.

SILVER WHEATON ANNUAL REPORT [71]

The Company is subject to taxation in Canada and various other foreign jurisdictions. The Company is currently open to audit under the statute of limitations by the Canada Revenue Agency for years ended December 31, 2004 through 2010.
