REPORT OF MANAGEMENT’S ACCOUNTABILITY
The accompanying consolidated financial statements have been prepared by management in accordance with Canadian generally accepted accounting principles. Management is responsible for ensuring that these statements, which include amounts based upon estimates and judgment, are consistent with other information and operating data contained in the annual financial review and reflect the corporation’s business transactions and financial position.
Management is also responsible for the information disclosed in the management’s discussion and analysis including responsibility for the existence of appropriate information systems, procedures and controls to ensure that the information used internally by management and disclosed externally is complete and reliable in all material respects.
In addition, management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. The internal control system includes an internal audit function and a code of conduct and ethics, which is communicated to all levels in the organization and requires all employees to maintain high standards in their conduct of the corporation’s affairs. Such systems are designed to provide reasonable assurance that the financial information is relevant, reliable and accurate and that the company’s assets are appropriately accounted for and adequately safeguarded. Management conducted an evaluation of the effectiveness of the system of internal control over financial reporting based on the criteria established in “Internal Control — Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that the company’s system of internal control over financial reporting was effective as at December 31, 2010.
KPMG LLP has audited the consolidated financial statements in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States).
The board of directors annually appoints an audit committee comprised of directors who are not employees of the corporation. This committee meets regularly with management, the internal auditor and the shareholders’ auditors to review significant accounting, reporting and internal control matters. Both the internal and shareholders’ auditors have unrestricted access to the audit committee. The audit committee reviews the financial statements, the report of the shareholders’ auditors, and management’s discussion and analysis and submits its report to the board of directors for formal approval.

INDEPENDENT AUDITORS’ REPORT
To the Shareholders of Cameco Corporation
We have audited the accompanying consolidated financial statements of Cameco Corporation (“the Corporation”), which comprise the consolidated balance sheets as at December 31, 2010 and 2009, the consolidated statements of earnings, shareholders’ equity, comprehensive income, accumulated other comprehensive income and cash flows for the years then ended, and notes, comprising a summary of significant accounting policies and other explanatory information.
Management’s Responsibility for the Consolidated Financial Statements
Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with Canadian generally accepted accounting principles, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.
Auditor’s Responsibility
Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with Canadian generally accepted auditing standards. Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.
An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Corporation’s preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Corporation’s internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.
We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion.
Opinion
In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of Cameco Corporation as at December 31, 2010 and 2009, and the results of its operations and its cash flows for the years then ended in accordance with Canadian generally accepted accounting principles.

Notes to Consolidated Financial Statements
For the years ended December 31, 2010 and 2009
($Cdn thousands, except per share amounts and as noted)

1. |  | Cameco Corporation
|  | Cameco Corporation is incorporated under the Canada Business Corporations Act. Cameco Corporation and its subsidiaries (collectively, Cameco or the company) are primarily engaged in the exploration for and the development, mining, refining, conversion and fabrication of uranium for sale as fuel for generating electricity in nuclear power reactors in Canada and other countries. The company has a 31.6% interest in Bruce Power L.P. (BPLP), which operates the four Bruce B nuclear reactors in Ontario.
2. |  | Significant Accounting Policies

| (a) |  | Consolidation Principles
|  |  | The consolidated financial statements include the accounts of Cameco and its subsidiaries. Interests in joint ventures are accounted for by the proportionate consolidation method. Under this method, Cameco includes in its accounts its proportionate share of assets, liabilities, revenues and expenses.
|  |  | The consolidated financial statements are prepared by management in accordance with Canadian generally accepted accounting principles. Management makes various estimates and assumptions in determining the reported amounts of assets and liabilities, revenues and expenses for each year presented, and in the disclosure of commitments and contingencies. The most significant estimates are related to the lives and recoverability of mineral properties, provisions for decommissioning and reclamation of assets, future income taxes, financial instruments and mineral reserves. Actual results could differ from these estimates. This summary of significant accounting policies is a description of the accounting methods and practices that have been used in the preparation of these consolidated financial statements and is presented to assist the reader in interpreting the statements contained herein.
| (b) |  | Cash and Cash Equivalents
|  |  | Cash and cash equivalents consist of balances with financial institutions and investments in money market instruments, which have a term to maturity of three months or less at time of purchase.
| (c) |  | Short-Term Investments
|  |  | Short-term investments consist of short-term money market instruments with terms to maturity at the date of acquisition of between three and 12 months. The short-term investments are classified as available-for-sale and are carried at fair value in the consolidated balance sheets with unrealized gains and losses reported in other comprehensive income (OCI). Realized gains and losses, as well as other-than-temporary declines in value, are recorded in the consolidated statements of earnings.
| (d) |  | Inventories
|  |  | Inventories of broken ore, uranium concentrates and refined and converted products are valued at the lower of average cost and net realizable value. Average cost includes direct materials, direct labour, operational overhead expenses and depreciation, depletion and reclamation. Net realizable value for finished products is considered to be the estimated selling price in the ordinary course of business, less the estimated costs of completion and selling expenses.
| (e) |  | Supplies
|  |  | Consumable supplies and spares are valued at the lower of cost or replacement value.
| (f) |  | Investments
|  |  | Investments in associated companies over which Cameco has the ability to exercise significant influence are accounted for by the equity method. Under this method, Cameco includes in earnings its share of earnings or losses of the associated company. Portfolio investments are classified as available-for-sale and are carried at fair value in the consolidated balance sheets with unrealized gains and losses reported in OCI. Realized gains and losses, as well as other-than-temporary declines in value, are recorded in the consolidated statements of earnings.

#####

| (g) |  | Property, Plant and Equipment
|  |  | Assets are carried at cost. Costs of additions and improvements are capitalized. When assets are retired or sold, the resulting gains or losses are reflected in current earnings. Maintenance and repair expenditures are charged to cost of production.
|  |  | The decision to develop a mine property within a project area is based on an assessment of the commercial viability of the property, the availability of financing and the existence of markets for the product. Once the decision to proceed to development is made, development and other expenditures relating to the project area are deferred and carried at cost with the intention that these costs will be depleted over the proven and probable reserves using the units-of-production method. No depreciation or depletion is charged against the property until commercial production commences. After a mine property has been brought into commercial production, costs of any additional work on that property are expensed as incurred, except for large development programs, which will be deferred and depleted over the remaining lives of the related assets.
|  |  | The carrying values of non-producing properties are periodically assessed by management and if management determines that the carrying values cannot be recovered, the unrecoverable amounts are written off against current earnings.
|  |  | Cameco reviews the carrying values of its property, plant and equipment when changes in circumstances indicate that those carrying values may not be recoverable. Estimated future net cash flows are calculated using estimated recoverable reserves, estimated future commodity prices and the expected future operating and capital costs. An impairment loss is recognized when the carrying value of an asset held for use exceeds the sum of undiscounted future net cash flows. An impairment loss is measured as the amount by which the asset’s carrying amount exceeds its fair value.
|  |  | Interest is capitalized on expenditures related to development projects actively being prepared for their intended use. Capitalization is discontinued when the asset enters commercial operation or development ceases.
|  |  | Fuel services assets, mine buildings, equipment and mineral properties are depreciated or depleted according to the units-of-production method. This method allocates the costs of these assets to each accounting period. For fuel services, the amount of depreciation is measured by the portion of the facilities’ total estimated lifetime production that is produced in that period. For mining, the amount of depreciation or depletion is measured by the portion of the mines’ proven and probable reserves which are recovered during the period.
|  |  | Nuclear generating plants are depreciated according to the straight-line method based on the lower of useful life and remaining lease term.
|  |  | Other assets are depreciated according to the straight-line method based on estimated useful lives, which generally range from three to 10 years.
| (h) |  | Intangible Assets
|  |  | Intangible assets acquired in a business combination are recorded at their fair values. Finite-lived intangible assets are amortized over the estimated production profile of the business unit to which they relate. The carrying values of intangible assets are periodically assessed by management and if management determines that the carrying values cannot be recovered, the unrecoverable amount is charged to earnings in the current period.
| (i) |  | Future Income Taxes
|  |  | Future income taxes are recognized for the future income tax consequences attributable to differences between the carrying values of assets and liabilities and their respective income tax bases. Future income tax assets and liabilities are measured using enacted or substantively enacted income tax rates expected to apply to taxable income in the years in which temporary differences are expected to be recovered or settled. The effect on future income tax assets and liabilities of a change in rates is included in earnings in the period, which includes the enactment date. Future income tax assets are recorded in the financial statements and a valuation allowance is provided, if necessary, to reduce the future income tax asset to an amount that is more likely than not to be realized. Accrued interest and penalties for uncertain tax positions are recognized in the period in which uncertainties are identified.

| (j) |  | Research and Development and Exploration Costs
|  |  | Expenditures for research and technology related to the products and processes are charged against earnings as incurred. Exploration expenditures including drilling and related costs are charged against earnings as incurred up until the point at which it is determined that the costs are economically recoverable. Any further exploration expenditures are capitalized once economic recoverability has been established.
| (k) |  | Environmental Protection and Asset Retirement Obligations
|  |  | The fair value of the liability for an asset retirement obligation is recognized in the period incurred. The fair value, discounted using the company’s credit adjusted risk-free rate, is added to the carrying amount of the associated asset and depreciated over the asset’s useful life. The liability is accreted over time, using the company’s credit adjusted risk-free rate, through periodic charges to earnings, and it is reduced by actual costs of decommissioning and reclamation. Cameco’s estimates of reclamation costs could change as a result of changes in regulatory requirements, reclamation plans, cost estimates and timing of estimated expenditures. Costs related to ongoing environmental programs are charged against earnings as incurred.
| (l) |  | Employee Future Benefits
|  |  | Cameco accrues its obligations under employee benefit plans. The cost of pensions and other retirement benefits earned by employees is actuarially determined using the projected benefit method pro-rated on service and management’s best estimate of expected plan investment performance, salary escalation, retirement ages of employees and expected health care costs. For the purpose of calculating the expected return on plan assets, those assets are measured at fair value. Cameco measures the plan assets and the accrued benefit obligations on December 31 each year.
|  |  | On both the Cameco-specific and BPLP-specific defined benefit pension plans, past service costs arising from plan amendments are amortized on a straight-line basis over the expected average remaining service life of the plan participants. Net actuarial gains, which exceed 10% of the greater of the accrued benefit obligation and the fair value of plan assets, are amortized on a straight-line basis over the expected average remaining service life of the plan participants.
|  |  | On the Cameco-specific retirement benefit plans that do not vest or accumulate, past service costs arising from plan amendments, and net actuarial gains and losses, are recognized in the period they arise. Conversely, the BPLP-specific amounts are amortized on a straight-line basis over the expected average remaining service life of the plan participants.
| (m) |  | Stock-Based Compensation
|  |  | Cameco has five stock-based compensation plans that are described in note 22. These encompass a stock option plan, an employee share ownership plan, a performance share unit plan, a deferred share unit plan and a phantom stock option plan. In calculating compensation expense, Cameco includes an estimate for forfeitures that is based on historic trends.
|  |  | Options granted under the stock option and performance share unit plans for which the holder cannot elect cash settlement are accounted for using the fair value method. Under this method, the compensation cost of options granted is measured at estimated fair value at the grant date and recognized over the shorter of the period to eligible retirement or the vesting period. Options that may be settled in cash are accounted for as liabilities and are carried at their intrinsic value. The intrinsic value of the liability is marked-to-market each period and is amortized to expense over the shorter of the period to eligible retirement or the vesting period.
|  |  | Deferred share units and phantom stock options are amortized over the shorter of the period to eligible retirement or the vesting period and re-measured at each reporting period, until settlement, using the quoted market value. Cameco’s contributions under the employee share ownership plan are expensed during the year of contribution. Shares purchased with company contributions and with dividends paid on such shares become unrestricted on January 1 of the second plan year following the date on which such shares were purchased.

| (n) |  | Revenue Recognition
|  |  | Cameco supplies uranium concentrates and uranium conversion services to utility customers.
|  |  | Cameco recognizes revenue on the sale of its nuclear products when evidenced by a contract that indicates the product, pricing and delivery terms, when delivery occurs, the related revenue is fixed or determinable and collection is reasonably assured.
|  |  | Cameco has three types of sales arrangements with its customers in its uranium and fuel services businesses. These arrangements include uranium supply, toll conversion services and conversion supply (converted uranium), which is a combination of uranium supply and toll conversion services.
|  |  | Uranium Supply
|  |  | In a uranium supply arrangement, Cameco is contractually obligated to provide uranium concentrates to its customers. Cameco-owned uranium is physically delivered to conversion facilities (Converters) where the Converter will credit Cameco’s account for the volume of accepted uranium. Based on delivery terms in a sales contract with its customer, Cameco instructs the Converter to transfer title of a contractually specified quantity of uranium to the customer’s account at the Converter’s facility. At this point, Cameco invoices the customer and recognizes revenue for the uranium supply.
|  |  | Toll Conversion Services
|  |  | In a toll conversion arrangement, Cameco is contractually obligated to convert customer-owned uranium to a chemical state suitable for enrichment. The customer delivers uranium to Cameco’s conversion facilities. Once conversion is complete, Cameco physically delivers converted uranium to enrichment facilities (Enrichers) where the Enricher will credit Cameco’s account for the volume of accepted processed uranium. Based on delivery terms in a sales contract with its customer, Cameco instructs the Enricher to transfer title of a contractually specified quantity of converted uranium to the customer’s account at the Enricher’s facility. At this point, Cameco invoices the customer and recognizes revenue for the toll conversion services.
|  |  | Conversion Supply
|  |  | In a conversion supply arrangement, Cameco is contractually obligated to provide uranium concentrates and conversion services to its customers. Cameco-owned uranium is converted and physically delivered to an Enricher as described in the toll conversion services arrangement. Based on delivery terms in a sales contract with its customer, Cameco instructs the Enricher to transfer title of a contractually specified quantity of converted uranium to the customer’s account at the Enricher’s facility. At this point, Cameco invoices the customer and recognizes revenue for both the uranium supplied and the conversion service provided. It is rare for Cameco to enter into back-to-back arrangements for uranium supply and toll conversion services. However, in the event that a customer requires such an arrangement, revenue from uranium supply is deferred until the toll conversion service has been rendered.
|  |  | Revenue from deliveries to counterparties with whom Cameco has arranged a standby product loan facility (up to the limit of the loan facilities) and the related cost of sales are deferred until the loan arrangements have been terminated, or if drawn upon, when the loans are repaid and that portion of the facility is terminated.
|  |  | Electricity sales are recognized at the time of generation, and delivery to the purchasing utility is metered at the point of interconnection with the transmission system. Revenues are recognized on an accrual basis, which includes an estimate of the value of electricity produced during the period but not yet billed.
| (o) |  | Amortization of Financing Costs
|  |  | For financial instruments that are measured at amortized cost, the effective interest method of amortization is used for any debt discounts and issue expenses. Unamortized costs are classified with their related financial liability.
| (p) |  | Foreign Currency Translation
|  |  | Monetary assets and liabilities denominated in foreign currencies are translated into Canadian dollars at year-end rates of exchange. Revenue and expense transactions denominated in foreign currencies are translated into Canadian dollars at rates in effect at the time of the transactions. The applicable exchange gains and losses arising on these transactions are reflected in earnings.

11

#####

|  |  | The United States (US) dollar is considered the functional currency of most of Cameco’s operations outside of Canada. The financial statements of these operations are translated into Canadian dollars using the current rate method whereby all assets and liabilities are translated at the year-end rate of exchange, and all revenue and expense items are translated at the average rate of exchange prevailing during the year. Exchange gains and losses arising from this translation, representing the net unrealized foreign currency translation gain (loss) on Cameco’s net investment in these foreign operations, are recorded in the foreign currency translation adjustments component of accumulated other comprehensive income (AOCI). Exchange gains or losses arising from the translation of foreign debt designated as hedges of a net investment in foreign operations are also recorded in the foreign currency translation adjustments component of AOCI. These adjustments are not included in earnings until realized through a reduction in Cameco’s net investment in such operations.
| (q) |  | Derivative Financial Instruments and Hedging Transactions
|  |  | Financial Assets and Financial Liabilities
|  |  | All financial assets and liabilities are carried at fair value in the consolidated balance sheets, except for items classified in the following categories, which are carried at amortized cost: loans and receivables, held-to-maturity securities and financial liabilities not held-for-trading. Realized and unrealized gains and losses on financial assets and liabilities that are held-for-trading are recorded in the consolidated statements of earnings. Unrealized gains and losses on financial assets that are available-for-sale are reported in OCI until realized, at which time they are recorded in the consolidated statements of earnings.
|  |  | Hedge Accounting and Derivatives
|  |  | Derivative financial and commodity instruments are employed by Cameco to reduce exposure to fluctuations in foreign currency exchange rates, interest rates and commodity prices. All derivative instruments are recorded at fair value in the consolidated balance sheets, except for those designated as hedging instruments.
|  |  | The purpose of hedging transactions is to modify Cameco’s exposure to one or more risks by creating an offset between changes in the fair value of, or the cash inflows attributable to, the hedged item and the hedging item. Hedge accounting ensures that the offsetting gains, losses, revenues and expenses are recognized to net earnings in the same period or periods. When hedge accounting is appropriate, the hedging relationship is designated as a fair value hedge, a cash flow hedge, or a foreign currency risk hedge related to a net investment in a self-sustaining foreign operation.
|  |  | At the inception of a hedging relationship, Cameco formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions. The process includes linking all derivatives to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. Cameco also formally assesses, both at the inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items.
|  |  | For fair value hedges, changes in the fair value of the derivatives and corresponding changes in fair value of the hedged items attributed to the risk being hedged are recognized in the consolidated statements of earnings. For cash flow hedges, the effective portion of the changes in the fair values of the derivative instruments are recorded in OCI until the hedged items are recognized in the consolidated statements of earnings. Derivative instruments that do not qualify for hedge accounting, or are not designated as hedging instruments, are marked-to-market and the resulting net gains or losses are recognized on the consolidated statements of earnings.
|  |  | Derivatives may be embedded in other financial instruments (the “host instrument”). Embedded derivatives are treated as separate derivatives when their economic characteristics and risks are not clearly and closely related to those of the host instrument, the terms of the embedded derivative are the same as those of a stand-alone derivative, and the combined contract is not held-for-trading or designated at fair value. These embedded derivatives are measured at fair value with subsequent changes recognized in gains or losses on derivatives on the consolidated statements of earnings.
| (r) |  | Earnings Per Share
|  |  | Earnings per share are calculated using the weighted average number of common shares outstanding.
|  |  | The calculation of diluted earnings per share assumes that outstanding options and warrants which are dilutive to earnings per share are exercised and the proceeds are used to repurchase shares of the company at the average market price of the shares for the period. The effect is to increase the number of shares used to calculate diluted earnings per share.

3. |  | Accounting Standards

| (a) |  | Future Changes in Accounting Policies
|  |  | International Financial Reporting Standards (IFRS)
|  |  | In February 2008, the Accounting Standards Board announced that Canadian publicly accountable enterprises will be required to adopt IFRS effective January 1, 2011. As a result, Cameco will publish its first consolidated financial statements, prepared in accordance with IFRS, for the quarter ending March 31, 2011. We will also provide comparative data on an IFRS basis, including an opening balance sheet as at January 1, 2010.

4. |  | Financial Risk Management
|  | This note presents information about various risks that Cameco is exposed to from its use of financial instruments, its objectives, policies and processes for measuring and managing risk, and the company’s management of capital. Further quantitative disclosures are included throughout these consolidated financial statements.
|  | Risk Management Overview
|  | Cameco is exposed in varying degrees to a variety of financial instrument related risks. Management and the board of directors, both separately and together, discuss the principal risks of our businesses. The board sets policies for the implementation of systems to manage, monitor and mitigate identifiable risks. Cameco’s risk management objective in relation to these instruments is to protect and minimize volatility in cash flow.
|  | Market Risk
|  | Cameco engages in various business activities which expose the company to market risk from changes in commodity prices and foreign currency exchange rates. As part of its overall risk management strategy, Cameco uses derivatives to manage some of its exposures to market risk that result from these activities.
|  | Derivative instruments may include financial and physical forward contracts. Such contracts may be used to establish a fixed price for a commodity, an interest-bearing obligation or a cash flow denominated in a foreign currency. Market risks are monitored regularly against defined risk limits and tolerances.
|  | Cameco’s actual exposure to these market risks is constantly changing as the company’s portfolios of foreign currency and commodity contracts change. Changes in fair value or cash flows based on market variable fluctuations cannot be extrapolated as the relationship between the change in the market variable and the change in fair value or cash flow may not be linear.
|  | The types of risk exposure and the way in which such exposure is managed are as follows:

| (a) |  | Commodity Price Risk
|  |  | As a significant producer and supplier of uranium, nuclear fuel processing and electricity, Cameco bears significant exposure to changes in prices for these products. A substantial change in prices will affect the company’s net earnings and operating cash flows. Prices for Cameco’s products are volatile and are influenced by numerous factors beyond the company’s control, such as supply and demand fundamentals, geopolitical events and, in the case of electricity prices, weather.
|  |  | Cameco’s sales contracting strategy focuses on reducing the volatility in future earnings and cash flow, while providing both protection against decreases in market price and retention of exposure to future market price increases. To mitigate the risks associated with the fluctuations in the market price for uranium products, Cameco seeks to maintain a portfolio of uranium product sales contracts with a variety of delivery dates and pricing mechanisms that provide a degree of protection from pricing volatility. To mitigate risks associated with fluctuations in the market price for electricity, BPLP enters into various energy and sales related contracts that qualify as cash flow hedges. At December 31, 2010, the effect of a $1/MWh increase in the market price for electricity would be a decrease of $175,000 in net earnings, and a decrease in other comprehensive income of $850,000 for 2010.

#####

| (b) |  | Foreign Exchange Risk
|  |  | The relationship between the Canadian and US dollars affects financial results of the uranium business as well as the fuel services business.
|  |  | Sales of uranium and fuel services are routinely denominated in US dollars while production costs are largely denominated in Canadian dollars. Cameco attempts to provide some protection against exchange rate fluctuations by planned hedging activity designed to smooth volatility. Cameco also has a natural hedge against US currency fluctuations because a portion of its annual cash outlays, including purchases of uranium and fuel services, is denominated in US dollars. At December 31, 2010, the effect of a $0.01 increase in the US to Canadian dollar exchange rate on our portfolio of currency hedges and other US denominated exposures would have been a decrease of $9,200,000 in net earnings for 2010.
| (c) |  | Counterparty Credit Risk
|  |  | Cameco’s sales of uranium product, conversion and fuel manufacturing services expose the company to the risk of non-payment. Counterparty credit risk is associated with the ability of counterparties to satisfy their contractual obligations to Cameco, including both payment and performance.
|  |  | Cameco manages this risk by monitoring the credit worthiness of our customers and seeking pre-payment or other forms of payment security from customers with an unacceptable level of credit risk.
|  |  | Cameco’s maximum counterparty credit exposure at the balance sheet date consists primarily of the carrying amount of financial assets such as accounts receivable and short-term investments. At December 31, 2010, there were no significant concentrations of credit risk and no amounts were held as collateral.
| (d) |  | Liquidity Risk
|  |  | Financial liquidity represents Cameco’s ability to fund future operating activities and investments. Cameco ensures that there is sufficient capital in order to meet short-term business requirements, after taking into account cash flows from operations and the company’s holdings of cash and cash equivalents. The company believes that these sources will be sufficient to cover the likely short-term and long-term cash requirements.
|  |  | The tables below outline the maturity dates for Cameco’s non-derivative financial liabilities including, principal and interest, as at December 31, 2010:

|  |  |  |  |  | Due in less |  |  | Due in |  |  | Due in |  |  | Due after |

#####

| (e) |  | Interest Rate Risk
|  |  | During the year, Cameco entered into interest rate swap arrangements whereby fixed rate payments in relation to part of the $300,000,000 Series C debenture were swapped for variable rate payments. The notional amount under the swap arrangements is $135,000,000. Concurrently, Cameco has entered into interest rate cap arrangements at a notional amount of $135,000,000 million that are effective March 18, 2013 and terminate on March 16, 2015. These interest rate cap arrangements, when effective, will limit Cameco’s interest rate exposure to 5% plus an average margin of 1.81%.
|  |  | At December 31, 2010, the effect of a 1% increase in the three-month bankers acceptance rate would be a decrease in net earnings of $3,570,000.

|  |  | Capital Management
|  |  | Cameco’s capital structure reflects our vision and the environment in which we operate. We seek growth through development and expansion of existing assets and by acquisition. Our capital resources are managed to support achievement of our goals. The overall objectives for managing capital remained unchanged in 2010 from the prior comparative period.
|  |  | Cameco’s management considers its capital structure to consist of long-term debt, short-term debt (net of cash and cash equivalents), minority interest and shareholders’ equity.
|  |  | The capital structure at December 31, 2010 was as follows:

(Thousands) |  | 2010 |  |  | 2009 |
Long-term debt |  | $ | 953,494 |  |  | $ | 964,482 |
Short-term debt |  |  | 72,948 |  |  |  | 76,762 |
Cash and cash equivalents |  |  | (376,621 | ) |  |  | (1,101,229 | )
Short-term investments |  |  | (883,032 | ) |  |  | (202,836 | )
Net debt |  |  | (233,211 | ) |  |  | (262,821 | )
Minority interest |  |  | 178,139 |  |  |  | 164,040 |
Shareholders’ equity |  |  | 5,216,327 |  |  |  | 4,843,828 |
Total equity |  |  | 5,394,466 |  |  |  | 5,007,868 |
Total capital |  | $ | 5,161,255 |  |  | $ | 4,745,047 |

|  | Cameco is bound by certain covenants in its general credit facilities. These covenants place restrictions on total debt, including guarantees, and set minimum levels for net worth. As of December 31, 2010, Cameco met these requirements.
5. |  | Short-Term Investments
|  | In 2010, Cameco purchased money market instruments with terms to maturity between three and 12 months. The fair values of marketable securities held at December 31, 2010 were $883,032,000 (2009 — $202,836,000).

(i) |  | BPLP leases the Bruce A nuclear generating plants and other property, plant and equipment to BALP under a sublease agreement. Future minimum base rent sublease payments under the capital lease receivable are imputed using a 7.5% discount rate.
(ii) |  | Through an unsecured shareholder loan, Cameco has agreed to fund the development of the Inkai project. The limit of the loan facility is $370,000,000 (US) and advances under the facility bear interest at a rate of LIBOR plus 2%. At December 31, 2010, $314,000,000 (US) of principal and interest was outstanding (2009 — $337,000,000 (US)), of which 40% represents the joint venture partner’s share.

10. |  | Short-Term Debt
|  | In 2008, a promissory note in the amount of $73,344,000 (US) was issued to finance the acquisition of GE-Hitachi Global Laser Enrichment LLC (GLE). The promissory note is payable on demand and bears interest at a market rate of 2.72%.
|  | In February 2009, Cameco concluded an arrangement for a $100,000,000 unsecured revolving credit facility. The original maturity date of the facility was February 5, 2010, however, in November 2010, upon mutual agreement with the lender, this facility was further extended to February 4, 2012. There are no longer any extensions available under this facility and there is no amount outstanding.

|  | Cameco has $300,000,000 outstanding in senior unsecured debentures (Series C). These debentures bear interest at a rate of 4.7% per annum (effective interest rate of 4.79%) and mature September 16, 2015.
|  | On September 2, 2009, Cameco issued debentures in the amount of $500,000,000. The debentures bear interest at 5.67% per annum (effective interest rate of 5.80%) and mature on September 2, 2019. The proceeds of the issue after deducting expenses were $495,300,000.
|  | Cameco has a $500,000,000 unsecured revolving credit facility that is available until November 30, 2012. In addition to direct borrowings under the facility, up to $100,000,000 can be used for the issuance of letters of credit and, to the extent necessary, up to $400,000,000 may be allocated to provide liquidity support for the company’s commercial paper program. The facility ranks equally with all of Cameco’s other senior debt. At December 31, 2010, there were no amounts outstanding under this credit facility (2009 — nil). Cameco may also borrow directly in the commercial paper market. There was no commercial paper outstanding at December 31, 2010 (2009 — nil). These amounts, when drawn, are classified as long-term debt.
|  | Cameco is bound by certain covenants in its revolving credit facilities. The significant financial covenants require a funded debt to tangible net worth ratio equal to or less than 1:1 and a tangible net worth greater than $1,250,000,000. Non-compliance with any of these covenants could result in accelerated payment and termination of the revolving credit facility. At December 31, 2010, Cameco was in compliance with covenants and does not expect its operating and investing activities in 2011 to be constrained by them.
|  | Cameco has $554,934,000 ($400,882,000 and $154,889,000 (US)) in letter of credit facilities. The majority of the outstanding letters of credit at December 31, 2010 relate to future decommissioning and reclamation liabilities [note 12] and amounted to $549,533,000 ($395,818,000 and $153,987,000 (US)) (2009 — $592,215,000 ($396,427,000 and $187,071,000 (US)).
|  | BPLP holds a long-term lease with OPG to operate the Bruce nuclear power facility. The term of the lease, which expires in 2018, is 18 years with an option to extend the lease for up to an additional 25 years. The interest rate associated with the lease is 7.5%.
|  | BPLP has a $200,000,000 (Cameco’s share $63,200,000) revolving credit facility that is available until July 30, 2013, as well as $270,000,000 (Cameco’s share $83,320,000) in letter of credit facilities. As at December 31, 2010, BPLP had $45,000,000 (Cameco’s share $14,220,000) outstanding under the revolving credit facility (2009 — $35,000,000 (Cameco’s share $11,060,000)) and $270,000,000 (Cameco’s share $85,320,000) outstanding under the letter of credit facilities (2009 — $184,000,000 (Cameco’s share $58,144,000)).

|  | Standby Product Loan Facilities
|  | Cameco had arranged for a standby product loan facility with one of its customers. The arrangement, which was finalized in 2008, allowed Cameco to borrow up to 2,400,000 pounds U3O8 equivalent over the period 2008 to 2011 with repayment during 2012 to 2014. Under the loan facility, standby fees of 2% were payable based on the market value of the facility, and interest was payable on the market value of any amounts drawn at a rate of 5%. Any borrowings were repayable in kind.
|  | On September 13, 2010, Cameco gave notice of termination to the counterparty of the product loan agreement. The loan facility was terminated on October 15, 2010.
12. |  | Provision for Reclamation
|  | Cameco’s estimates of future asset retirement obligations are based on reclamation standards that satisfy regulatory requirements. Elements of uncertainty in estimating these amounts include potential changes in regulatory requirements, decommissioning and reclamation alternatives and amounts to be recovered from other parties.
|  | Cameco estimates total future decommissioning and reclamation costs for its operating assets to be $465,709,000. These estimates are reviewed by Cameco technical personnel as required by regulatory agencies or more frequently as circumstances warrant. In connection with future decommissioning and reclamation costs, Cameco has provided financial assurances of $548,933,000 in the form of letters of credit to satisfy current regulatory requirements.
|  | Under the BPLP lease agreement, OPG, as the owner of the Bruce nuclear plants, is responsible to decommission the Bruce facility and to provide funding and meet other requirements that the Canadian Nuclear Safety Commission (CNSC) may require of BPLP as licensed operator of the Bruce facility. OPG is also responsible to manage radioactive waste associated with decommissioning of the Bruce nuclear plants.

|  | In 2008, as part of the ongoing annual audits of Cameco’s Canadian tax returns, Canada Revenue Agency (CRA) disputed the transfer pricing methodology used by Cameco and its wholly owned Swiss subsidiary, Cameco Europe Ltd. (CEL), in respect of sale and purchase agreements for uranium products. In December 2008, CRA issued a notice of reassessment, which increased Cameco’s 2003 income for Canadian income tax purposes by approximately $43,000,000. Additional reassessments for 2003 were issued by CRA in 2009 and 2010, both to similar effect. In December 2009, CRA issued a notice of reassessment for the 2004 taxation year, which increased Cameco’s 2004 income by approximately $108,000,000. Another reassessment for 2004 was issued by CRA on May 13, 2010 to similar effect. In December 2010, CRA issued a notice of reassessment for the 2005 taxation year, which increased Cameco’s 2005 taxable income by approximately $197,000,000. No reassessment received to date has resulted in more than a nominal amount of cash taxes becoming payable due to the availability of elective deductions and tax loss carrybacks. Cameco believes it is likely that CRA will reassess Cameco’s tax returns for the years 2006 through 2010 on a similar basis.
|  | CRA’s Transfer Pricing Review Committee is scheduled to meet in late February, 2011, to decide whether to impose a penalty for 2005. Given that the Transfer Pricing Review Committee did not impose a transfer pricing penalty for 2003 or 2004, we do not expect that a penalty will be imposed for 2005.
|  | Having regard to advice from its external advisors, Cameco’s opinion is that CRA’s position is incorrect, and Cameco is contesting CRA’s position. However, to reflect the uncertainties of CRA’s appeals process and litigation, Cameco has recorded a cumulative tax provision related to this matter for the years 2003 through 2010 in the amount of $27,000,000. No provisions for penalties or interest have been recorded. We do not expect more than a nominal amount of cash taxes to be payable due to availability of elective deductions and tax loss carryovers. While the resolution of this matter may result in liabilities that are higher or lower than the reserve, management believes that the ultimate resolution will not be material to Cameco’s financial position, results of operations or liquidity over the period. However, an unfavourable outcome for the years 2003 to 2010 could be material to Cameco’s financial position, results of operations or cash flows in the year(s) of resolution.
|  | Further to Cameco’s decision to contest CRA’s reassessments, a Notice of Appeal for the 2003 taxation year was filed with the Tax Court of Canada on July 22, 2009, and amended on January 26, 2011, and the litigation process is proceeding. In connection with CRA’s 2004 reassessment, Cameco is contesting the reassessment and pursuing its appeal rights under the Income Tax Act. A Notice of Appeal for the 2004 taxation year was filed with the Tax Court of Canada on November 10, 2010. Cameco intends to object to the 2005 reassessment and pursue its appeal rights under the Income Tax Act.

20. |  | Uranium Joint Ventures
|  | Cameco conducts a portion of its exploration, development, mining and milling activities through joint ventures. Cameco proportionately consolidates its ownership interest in these assets. The McArthur River, Key Lake and Cigar Lake joint ventures allocate uranium production to each joint venture participant and the joint venture participant derives revenue directly from the sale of such product. Mining and milling expenses incurred by the joint venture are included in the cost of inventory.
|  | The participants in the Inkai joint venture purchase uranium from Inkai and, in turn, derive revenue directly from the sale of such product to third party customers. On proportionate consolidation of Inkai, Cameco eliminates revenues and cost of sales recorded by Inkai related to sales by Inkai directly to Cameco. After elimination of these related party sales for the period, there are no revenues and expenses resulting from proportionate consolidation of Inkai and accordingly, a statement showing revenues and expenses from Inkai has not been provided.

22. |  | Stock-Based Compensation Plans
|  | Stock Option Plan
|  | Cameco has established a stock option plan under which options to purchase common shares may be granted to officers and other employees of Cameco. Options granted under the stock option plan have an exercise price of not less than the closing price quoted on the TSX for the common shares of Cameco on the trading day prior to the date on which the option is granted. The options vest over three years and expire eight years from the date granted. Options have not been awarded to directors since 2003 and the plan has been amended to preclude the issue of options to directors.
|  | The aggregate number of common shares that may be issued pursuant to the Cameco stock option plan shall not exceed 43,017,198, of which 26,092,439 shares have been issued.

|  | The foregoing options have expiry dates ranging from March 9, 2011 to March 2, 2018.
|  | Non-vested stock option transactions for the respective years were as follows:

(Number of Options) |  | 2010 |  |  | 2009 |
Beginning of year |  |  | 2,389,685 |  |  |  | 2,163,426 |

End of year |  |  | 2,737,618 |  |  |  | 2,389,685 |

|  | For the year ended December 31, 2010, Cameco has recorded a net expense of $8,931,000 (2009 - $4,372,000), related to options that vested during the year.

|  | The fair value of the options granted each year was determined using the Black-Scholes option-pricing model with the following weighted average assumptions:

|  | 2010 |  |  | 2009 |

|  | Executive Performance Share Unit (PSU), Deferred Share Unit (DSU), and Other Plans
|  | Commencing in 2005, Cameco provides each plan participant an annual grant of PSUs in an amount determined by the board. Each PSU represents one phantom common share that entitles the participant to a payment of one Cameco common share purchased on the open market, or cash at the board’s discretion, at the end of each three-year period if certain performance and vesting criteria have been met. The final value of the PSUs will be based on the value of Cameco common shares at the end of the three-year period and the number of PSUs that ultimately vest. Vesting of PSUs at the end of the three-year period will be based on total shareholder return over the three years, Cameco’s ability to meet its annual cash flow from operations targets and whether the participating executive remains employed by Cameco at the end of the three-year vesting period. As of December 31, 2010, the total PSUs held by the participants was 395,360 (2009 – 233,710). In 2010, Cameco recognized an expense of $3,679,000 in relation to PSUs (2009 - $3,347,000).
|  | Cameco offers a deferred share unit plan to non-employee directors. A DSU is a notional unit that reflects the market value of a single common share of Cameco. 60% of each director’s annual retainer is paid in DSUs. In addition, on an annual basis, directors can elect to receive 25%, 50%, 75% or 100% of the remaining 40% of their annual retainer and any additional fees in the form of DSUs. If a director meets their ownership requirements, the director may elect to take 25%, 50%, 75% or 100% of their annual retainer and any fees in cash, with the balance, if any, to be paid in DSUs. Each DSU fully vests upon award. The DSUs will be redeemed for cash upon a director leaving the board. The redemption amount will be based upon the weighted average of the closing prices of the common shares of Cameco on the TSX for the last 20 trading days prior to the redemption date multiplied by the number of DSUs held by the director. As of December 31, 2010, the total DSUs held by participating directors was 354,276 (2009 – 373,921).

|  | Cameco makes annual grants of bonuses to eligible non-North American employees in the form of phantom stock options. Employees receive the equivalent value of shares in cash when exercised. Options granted under the phantom stock option plan have an award value equal to the closing price quoted on the TSX for the common shares of Cameco on the trading day prior to the date on which the option is granted. The options vest over three years and expire eight years from the date granted. As of December 31, 2010, the number of options held by participating employees was 242,051 (2009 –267,148) with exercise prices ranging from $5.88 to $46.88 per share (2009 - $5.88 to $46.88) and a weighted average exercise price of $30.00 (2009 — $30.61).
|  | Commencing in 2007, Cameco created an employee share ownership plan whereby both employee and company contributions are used to purchase shares on the open market for employees. The company’s contributions are expensed during the year of contribution. Under the plan, all employees have the opportunity to participate in the program to a maximum of 6% of eligible earnings each year with Cameco matching the first 3% of employee-paid shares by 50%. Cameco contributes $1,000 of shares annually to each employee that is enrolled in the plan. At December 31, 2010, there were 3,496 participants in the plan (2009 – 3,306). The total number of shares purchased in 2010 on behalf of participants, including the company contribution, was 214,795 shares (2009 – 281,207). In 2010, the company’s contributions totaled $6,608,000 (2009 — $5,166,000).
|  | Cameco has recognized the following expenses under these plans:

|  | 2010 |  |  | 2009 |
Deferred share units |  |  | 1,971 |  |  |  | 4,930 |
Phantom stock options |  |  | 979 |  |  |  | 1,531 |
Employee share ownership plan |  |  | 6,608 |  |  |  | 5,166 |

|  | At December 31, 2010, a liability of $16,798,000 (2009 — $14,962,000) was included in the balance sheet to recognize accrued but unpaid expenses for these plans.

23. |  | Pension and Other Post-Retirement Benefits
|  | Cameco maintains both defined benefit and defined contribution plans providing pension and post-retirement benefits to substantially all of its employees.
|  | Under the defined pension benefit plans, Cameco provides benefits to retirees based on their length of service and final average earnings. The non-pension post-retirement plan covers such benefits as group life and supplemental health insurance to eligible employees and their dependants. The costs related to the non-pension post-retirement plans are charged to earnings in the period during which the employment services are rendered. However, these future obligations are not funded.
|  | The effective date for the most recent valuations for funding purposes on the pension benefit plans is January 1, 2009. The next planned effective date for valuation for funding purposes of the pension benefit plans is set to be January 1, 2012. The status of the defined plans is as follows:

BPLP
BPLP has a funded registered pension plan and an unfunded supplemental pension plan. The funded plan is a contributory, defined benefit plan covering all employees up to the limits imposed by the Income Tax Act. The supplemental pension plan is a non-contributory, defined benefit plan covering all employees with respect to benefits that exceed the limits under the Income Tax Act. These plans are based on years of service and final average salary.
BPLP also has other post-retirement benefit and other post-employment benefit plans that provide for group life insurance, health care and long-term disability benefits. These plans are non-contributory.
The effective date for the most recent valuations for funding purposes on the pension benefit plans is January 1, 2010. The next planned effective date for valuation for funding purposes of the pension benefit plans is set to be January 1, 2011. The status of Cameco’s proportionate share (31.6%) of the defined plans is as follows:

|  | The assets of the pension plan are managed on a going concern basis subject to legislative restrictions. The plan’s investment policy is to maximize returns within an acceptable risk tolerance. Pension assets are invested in a diversified manner with consideration given to the demographics of the plan participants. Rebalancing will take place on a monthly basis if outside of 3% of the target asset allocation.

24. |  | Restructuring of the Gold Business
|  | The assets and liabilities related to discontinued operations have been reclassified as assets or liabilities of discontinued operations on the consolidated balance sheets. Operating results related to the discontinued operations have been included in earnings from discontinued operations on the consolidated statements of earnings. Comparative period balances have been restated.

| (a) |  | Sale of Centerra Gold Inc. (Centerra)
|  |  | On December 30, 2009, Cameco completed a public offering of 88,618,472 common shares of Centerra for net proceeds of approximately $871,000,000 and recorded a net gain of $374,000,000. Concurrent with this offering, Cameco transferred an additional 25,300,000 common shares of Centerra to Kyrgyzaltyn pursuant to the agreement that Cameco entered into with the Government of the Kyrgyz Republic on April 24, 2009. As a result of the closing of the public offering, and the transfer of the Centerra common shares to Kyrgyzaltyn, Cameco has disposed of its entire interest in Centerra.
| (b) |  | Kyrgyz Share Transfer
|  |  | In 2007, the Parliament of the Kyrgyz Republic challenged the legal validity of Kumtor Gold Company (Kumtor) agreements with the Kyrgyz Republic. As a result, Cameco and Centerra entered into discussions with Kyrgyzaltyn, culminating in the signing of two agreements in August 2007 providing for the transfer of a certain number of Centerra shares to Kyrgyzaltyn, subject to certain conditions. These agreements, however, were never ratified by the Kyrgyz parliament.
|  |  | On April 24, 2009, Cameco, Centerra, the Kyrgyz government and other parties signed a new agreement to resolve all the issues related to the Kumtor mine. On April 30, 2009, the Kyrgyz parliament ratified the agreement and enacted legislation authorizing implementation of the agreement. On June 11, 2009, closing occurred and Centerra issued 18,232,615 treasury shares to Kyrgyzaltyn and Cameco transferred 25,300,000 shares of its 113,918,000 Centerra common shares to a custodian, to be held in escrow, for ultimate release to Kyrgyzaltyn, subject to certain conditions. Cameco retained its voting rights over these shares while they were held in escrow. As a result of the public offering concluded on December 30, 2009, Cameco released the shares held in escrow to Kyrgyzaltyn.
|  |  | The total amount of the after-tax loss related to this agreement is $179,000,000, of which an expense of $46,000,000 was recorded in 2009, a recovery of $20,000,000 in 2008 and an expense of $153,000,000 in 2007.
| (c) |  | Financial Results of Discontinued Operations
|  |  | The results of the operations of Centerra are presented under “discontinued operations” on the consolidated statements of earnings. The following table presents the components of the discontinued operations amounts, net of future income tax expenses [note 18]:

25. |  | Commitments and Contingencies

| (a) |  | On February 12, 2004, Cameco, Cameco Bruce Holdings II Inc., BPC Generation Infrastructure Trust and TransCanada Pipelines Limited (collectively, the “Consortium”) sent a notice of claim to British Energy Limited and British Energy International Holdings Limited (collectively, BE) requesting, amongst other things, indemnification for breach of a representation and warranty contained in the February 14, 2003, Amended and Restated Master Purchase Agreement. The alleged breach is that the Unit 8 steam generators were not “in good condition, repair and proper working order, having regard to their use and age.” This defect was discovered during a planned outage conducted just after closing. As a result of this defect, the planned outage had to be significantly extended. The Consortium has claimed damages in the amount of $64,558,200 being 79.8% of the $80,900,000 of damages actually incurred, plus an unspecified amount to take into account the reduced operating life of the steam generators. By agreement of the parties, an arbitrator has been appointed to arbitrate the claims and a schedule has been set for the next steps in the proceeding.
|  |  | The Consortium served its claim on October 21, 2008, and has amended it as required, most recently on August 7, 2009. BE served its answer and counter-statement on December 22, 2008, most recently amended on March 25, 2010, and the Consortium served its reply and answer to counter-statement on January 22, 2009, most recently amended on August 7, 2009.
|  |  | The Unit 8 steam generators require on-going monitoring and maintenance as a result of the defect. In addition to the $64,558,200 in damages sought in the notice of claim, the claim seeks an additional $4,900,000 spent on inspection, monitoring and maintenance of Unit 8, and $31,900,000 in costs for future monitoring and maintenance, as well as repair costs and lost revenue due to anticipated unplanned outages as a consequence of the defect in Unit 8. The initial claim had also sought damages for the early replacement of the Unit 8 steam generators due to the defect shortening their useful operating lives. However, recent inspection data and analysis of the condition of the Unit 8 steam generators now indicates that they will continue to function until the end of the Consortium’s lease of the Bruce Power facility in 2018, as was expected at the time the MPA was entered into. The claim for early replacement was thus abandoned via an amendment to the claim on August 7, 2009. The arbitration hearing was completed on November 23, 2010 and final oral arguments are scheduled for June 1, 2011.
|  |  | In anticipation of this claim, BE issued on February 10, 2006, and then served on Ontario Power Generation Inc. (OPG) and Bruce Power LP a Statement of Claim. This Statement of Claim seeks damages for any amounts that BE is found liable to pay to the Consortium in connection with the Unit 8 steam generator arbitration described above, damages in the amount of $500,000,000, costs and pre and post judgment interest amongst other things. Further proceedings in this action are on hold pending completion of the arbitration hearing.
| (b) |  | Annual supplemental rents of $30,000,000 (subject to CPI) per operating reactor are payable by BPLP to OPG. Should the hourly annual average price of electricity in Ontario fall below $30 per megawatt hour, the supplemental rent reduces to $12,000,000 per operating reactor. In accordance with the Sublease Agreement, Bruce A L.P. will participate in its share of any adjustments to the supplemental rent.

#####

(c) |  | Cameco, TransCanada and BPC have assumed the obligations to provide financial guarantees on behalf of BPLP. Cameco has provided the following financial assurances, with varying terms that range from 2011 to 2018:

| i) |  | Guarantees to customers under power sales agreements of up to $35,300,000. At December 31, 2010, Cameco’s actual exposure under these guarantees was $24,000,000.
| ii) |  | Termination payments to OPG pursuant to the lease agreement of $58,300,000. The fair value of these guarantees is nominal.

(d) |  | Under a supply contract with the Ontario Power Authority (OPA), BPLP is entitled to receive payments from the OPA during periods when the market price for electricity in Ontario is lower than the floor price defined under the agreement during a calendar year. On July 6, 2009, BPLP and the OPA amended the supply contract such that beginning in 2009, the annual payments received will not be subject to repayment in future years. Previously, the payments received under the agreement were subject to repayment during the entire term of the contract, dependent on the spot price in future periods. BPLP’s entitlement to receive these payments remains in effect until December 31, 2019 but the generation that is subject to these payments starts to decrease in 2016, reflecting the original estimated lives for the Bruce B units. During 2010, BPLP recorded $339,000,000 under this agreement which was recognized as revenue with Cameco’s share being $107,000,000. Of the amount recorded, BPLP currently expects to repay $4,000,000.

(e) |  | Cameco’s North American workforce includes about 3,300 employees, of which approximately 900 (27%) belong to three separate labour unions.

(f) |  | At December 31, 2010, Cameco’s purchase commitments, the majority of which are fixed price uranium and conversion purchase arrangements, were as follows:

|  | (Millions (US)) |
2011 |  | $ | 267 |
2012 |  |  | 226 |
2013 |  |  | 397 |
2014 |  |  | 114 |
2015 |  |  | 60 |
Thereafter |  |  | 6 |
Total |  | $ | 1,070 |

26. |  | Financial Instruments
|  | The majority of revenues at Cameco are derived from the sale of uranium products, and electricity through its investment in BPLP. Cameco’s uranium product financial results are closely related to the long and short-term market price of uranium sales and conversion services. Prices fluctuate and can be affected by demand for nuclear power, worldwide production and uranium levels, and political and economic conditions in uranium producing and consuming countries. BPLP’s revenue from electricity is affected by changes in electricity prices associated with an open spot market for electricity in Ontario. Financial results for Cameco are also impacted by changes in foreign currency exchange rates and other operating risks. Finally, certain financial assets are subject to credit risks, including cash and securities, accounts receivable, and commodity and currency instruments.
|  | To mitigate risks associated with certain financial assets, Cameco will hold positions with a variety of large creditworthy institutions. Sales of uranium products, with short payment terms, are made to customers that management believes are creditworthy.
|  | To mitigate risks associated with foreign currency on its sale of uranium products, Cameco enters into forward sales contracts to establish a price for future delivery of the foreign currency.

38

#####

|  | Cameco is exposed to interest rate risk through its interest rate swap contracts whereby fixed rate payments on a notional amount of $135,000,000 of the Series C senior unsecured debentures were swapped for variable rate payments. The swaps terminate on March 16, 2015. Under the terms of the swaps, Cameco makes interest payments based on three-month bankers acceptance rate plus an average margin of 1.81% and receives fixed interest payments of 4.7%. To mitigate this risk, Cameco entered into interest rate cap arrangements, effective March 18, 2013, whereby the three-month bankers acceptance rate was capped at 5.0% such that total variable payments will not exceed, on average 6.81%. At December 31, 2010, the mark-to-market gain on Cameco’s interest rate swaps and caps less premiums paid was $1,458,000.

|  | To mitigate risks associated with the fluctuations in the market price for uranium products, Cameco seeks to maintain a portfolio of uranium product sales contracts with a variety of delivery dates and pricing mechanisms that provide a degree of protection from price volatility. To mitigate risks associated with the fluctuations in the market price for electricity, BPLP enters into various energy and sales related contracts that qualify as cash flow hedges. These instruments have terms ranging from 2011 to 2016. At December 31, 2010, the mark-to-market gain on BPLP’s sales contracts was $29,000,000.

|  | All financial instruments measured at fair value are categorized into one of three hierarchy levels, described below, for disclosure purposes. Each level is based on the transparency of the inputs used to measure the fair values of assets and liabilities:

Level 1 – Values based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities.
Level 2 – Values based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the asset or liability.
Level 3 – Values based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement.

|  | When the inputs used to measure fair value fall within more than one level of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measure in its entirety.

|  | Except as otherwise disclosed, the fair market value of Cameco’s financial assets and liabilities approximates the carrying amount as a result of the short-term nature of the instruments, or the variable interest rate associated with the instruments, or the fixed interest rate of the instruments being similar to market rates.

|  | The fair values of Cameco’s privately held available-for-sale securities, as described in note 9, have not been disclosed because of the unavailability of a quoted market price in an active market. Cameco does not currently have plans to dispose of any of these investments.

|  | The fair value of a financial instrument is the amount at which the financial instrument could be exchanged in an arm’s-length transaction between knowledgeable and willing parties under no compulsion to act. Fair values of identical instruments traded in active markets are determined by reference to last quoted prices, in the most advantageous active market for that instrument. In the absence of an active market, we determine fair values based on quoted prices for instruments with similar characteristics and risk profiles. Fair values of financial instruments determined using valuation models require the use of inputs. In determining those inputs, we look primarily to external, readily observable market inputs, when available, including factors such as interest rate yield curves, currency rates, and price and rate volatilities, as applicable. In some circumstances, we use input parameters that are not based on observable market data. In these cases, we may adjust model values to reflect the valuation uncertainty in order to determine what the fair value would be based on the assumptions that market participants would use in pricing the financial instrument. These adjustments are made in order to determine the fair value of the instruments.

|  | We make valuation adjustments for the credit risk of our derivative portfolios in order to arrive at their fair values. These adjustments take into account the creditworthiness of our counterparties.

|  | Equity-accounted investments and financial instruments classified as available-for-sale comprise actively traded debt and equity securities and are carried at fair value based on available quoted prices.

|  | There were no significant transfers between level 1 and level 2 of the fair value hierarchy. Transfers into level 3 are comprised of BPLP derivative financial instruments with contract terms extending beyond 36 months. Due to the decline in electricity prices as a result of the recession, the liquidity in the market has been significantly reduced, resulting in a lack of an active market and observable market inputs beyond 36 months.

|  | These positions consist entirely of forward sales contracts. The average exchange rate reflects the current forward contract price. Of these amounts, $1,252,500,000 of the US-denominated contracts and $93,000,000 of the Euro-denominated contracts mature in 2011. The remaining $65,000,000 in US-denominated contracts matures in 2012.

| (c) |  | Major Customers
|  |  | Cameco relies on a small number of customers to purchase a significant portion of its uranium concentrates and uranium conversion services. During 2010, revenues from one customer of Cameco’s uranium and fuel services segments represented approximately $125,657,000 (2009 — $252,699,000), about 8% (2009 — 14%) of Cameco’s total revenues from these segments. As customers are relatively few in number, accounts receivable from any individual customer may periodically exceed 10% of accounts receivable depending on delivery schedules.
|  |  | During 2010, electricity revenues from one customer of BPLP represented approximately 7% (2009 — 5%) of BPLP’s total revenues.

29. |  | Talvivaara Agreement

|  | On February 7, 2011, Cameco signed two agreements with Talvivaara Mining Company Plc. to buy uranium produced at the Sotkamo nickel-zinc mine in Finland. Under the first agreement with Talvivaara, Cameco will provide an up-front payment, to a maximum of $60,000,000 (US) to cover certain construction costs. This amount will be repaid through deliveries of uranium concentrate. Once the full amount has been repaid, Cameco will continue to purchase the uranium concentrates produced at the Sotkamo mine through a second agreement which provides for the purchase of uranium using a pricing formula that references market prices at the time of delivery. The second agreement expires on December 31, 2027.

30. |  | Related Party Transactions

|  | Cameco purchases a significant amount of goods and services for its Saskatchewan mining operations from northern Saskatchewan suppliers to support economic development in the region. One such supplier is Points Athabasca Contracting Ltd. and the president of the company became a member of the board of directors of Cameco during 2009. In 2010, Cameco paid Points Athabasca Contracting Ltd. $38,000,000 (2009 — $30,800,000) for construction and contracting services. The transactions were conducted in the normal course of business and were accounted for at the exchange amount. Accounts payable include a balance of $2,290,000 (2009 — $230,000) resulting from these transactions.
