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 report 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.
The integrity and reliability of Cameco’s reporting systems are achieved through the use of formal policies and procedures, the careful selection of employees and appropriate delegation of authority and division of responsibilities. Internal accounting controls are monitored by the internal auditor. Cameco’s code of conduct and ethics, which is communicated to all levels in the organization, requires employees to maintain high standards in their conduct of the corporation’s affairs.
Our shareholders’ independent auditors, KPMG LLP, whose report on their examination follows, have audited the consolidated financial statements in accordance with Canadian generally accepted auditing standards.
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.

Auditors’ Report
To the Shareholders of Cameco Corporation
We have audited the consolidated balance sheets of Cameco Corporation as at December 31, 2005 and 2004 and the consolidated statements of earnings, retained earnings and cash flows for each of the years in the three-year period ended December 31, 2005. These financial statements are the responsibility of the corporation’s management. Our responsibility is to express an opinion on these financial statements based on our audits.
We conducted our audits in accordance with Canadian generally accepted auditing standards. Those standards require that we plan and perform an audit to obtain reasonable assurance 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.
In our opinion, these consolidated financial statements present fairly, in all material respects, the financial position of the corporation as at December 31, 2005 and 2004 and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2005 in accordance with Canadian generally accepted accounting principles.

Notes to Consolidated Financial Statements

|  | For the years ended December 31, 2005, 2004 and 2003
|  | ($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 and conversion 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. Cameco’s 52.7% subsidiary Centerra Gold Inc. (“Centerra”) is involved in the exploration for and the development, mining and sale of gold.
2. |  | Accounting Policies

| (a) |  | Significant Accounting Policies
|  |  | A summary of significant accounting policies follows the notes to the consolidated financial statements.
| (b) |  | New Accounting Pronouncements

| (i) |  | In January 2005, the CICA issued four new accounting standards: Handbook Section 1530, Comprehensive Income, Handbook Section 3251, Equity, Handbook Section 3855, Financial Instruments — Recognition and Measurement and Handbook Section 3865, Hedges.These standards are effective for interim and annual financial statements for Cameco’s fiscal years beginning January 1, 2007. The impact of implementing these new standards is not yet determinable as it is dependent on Cameco’s outstanding positions, hedging strategies and market volatility.
|  |  | Comprehensive income
|  |  | In January 2005, the CICA issued new standards for the reporting and display of comprehensive income.
|  |  | Unrealized gains and losses on financial assets that will be held as available for sale, unrealized foreign currency translation amounts arising from self-sustaining foreign operations, and changes in the fair value of cash flow hedging instruments, will be recorded in the Consolidated Statement of Other Comprehensive Income until recognized in the Consolidated Statement of Earnings.Other comprehensive income will form part of shareholders’ equity.
|  |  | Equity
|  |  | In January 2005, the CICA issued revised standards requiring an enterprise to present a separate component of equity for each category of equity that is of a different nature. Financial instruments
|  |  | Disclosure and presentation
|  |  | In April 2005, the CICA issued revised standards addressing the presentation and disclosure of financial instruments and non-financial derivatives.
|  |  | Recognition and measurement
|  |  | In January 2005, the CICA issued new standards for the recognition and measurement of financial instruments. Under the new standard, all financial instruments will be classified as one of the following: held to maturity, loans and receivables, held for trading or available for sale. Financial assets and liabilities held for trading will be measured at fair value with gains and losses recognized in net earnings. Financial assets held to maturity, loans and receivables and financial liabilities other than those held for trading, will be measured at amortized cost. Available-for-sale instruments will be measured at fair value with gains and losses recognized in other comprehensive income. The standard permits re-designation of any financial instrument as held for trading.

|  |  | Hedges In January 2005, the CICA issued new standards which specify the circumstances under which hedge accounting is permissible and how hedge accounting may be performed.
|  |  | Fair value hedges, cash flow hedges and hedges of a net investment in a foreign operation are permissible under the new section. In a fair value hedging relationship, the carrying value of the hedged item is adjusted by gains or losses attributable to the hedged risk and recorded in net earnings. This change in fair value of the hedged item, to the extent that the hedging relationship is effective, is offset by changes in the fair value of the derivative. In a cash flow hedging relationship, the effective portion of the change in fair value of the hedging derivative will be recognized in other comprehensive income. The ineffective portion will be recognized in net earnings. The amounts recognized in accumulated other comprehensive income will be reclassified to net earnings in the periods in which earnings are affected by the variability in the cash flows of the hedged item.
| (ii) |  | Non-monetary transactions
|  |  | In June 2005, the CICA issued Handbook Section 3831, which provides revised standards on non-monetary transactions requiring that all non-monetary transactions be measured at fair value unless certain criteria are met.
|  |  | These standards are effective for all non-monetary transactions initiated after January 1, 2006. Cameco does not anticipate that the adoption of this standard will have a material impact on its consolidated financial statements.

On September 25, 2003 the company issued unsecured convertible debentures in the amount of $230,000,000. The debentures bear interest at 5% per annum, mature on October 1, 2013, and at the holder’s option are convertible into common shares of Cameco.The fair value of the conversion option associated with the convertible debentures on the date of issuance was $30,473,000, resulting in an effective interest rate of 6.85%.The amount is reflected as contributed surplus.The conversion price is $10.83 per share, a rate of approximately 92.3 common shares per $1,000 of convertible debentures. Interest is payable semi-annually in arrears on April 1 and October 1.The debentures are redeemable by the company beginning October 1, 2008 at a redemption price of par plus accrued and unpaid interest.
The fair value of the outstanding convertible debentures is based on the quoted market price of the debentures at December 31, 2005 and was approximately $794,000,000.
Cameco has $100,000,000 outstanding in senior unsecured debentures (Series A) that bear interest at a rate of 6.9% per annum and mature July 12, 2006.

7. 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 $239,000,000. 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 $203,300,000 in the form of letters of credit to satisfy current regulatory requirements.
Following is a reconciliation of the total liability for asset retirement obligations:

|  | 2005 |  |  | 2004 |  |  | 2003 |
Balance, beginning of year |  | $ | 166,941 |  |  | $ | 150,444 |  |  | $ | 159,344 |

Balance, end of year |  | $ | 167,568 |  |  | $ | 166,941 |  |  | $ | 150,444 |

Following is a summary of the key assumptions on which the carrying amount of the asset retirement obligations is based:

(i) |  | Total undiscounted amount of the estimated cash flows – $239,000,000.
(ii) |  | Expected timing of payment of the cash flows – timing is based on life of mine plans. The majority of expenditures are expected to occur after 2013.
(iii) |  | Discount rates – 7.5% for operations in North America; 8.0% for operations in Kyrgyzstan; 8.5% for operations in Mongolia.

The asset retirement obligations liability is comprised of:

|  | 2005 |  |  | 2004 |
Uranium |  | $ | 101,573 |  |  | $ | 96,803 |
Conversion |  |  | 44,923 |  |  |  | 47,090 |
Gold |  |  | 21,072 |  |  |  | 23,048 |
Total |  | $ | 167,568 |  |  | $ | 166,941 |

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.

15. Joint Ventures
Cameco conducts a portion of its exploration, development, mining and milling activities through joint ventures. Cameco’s significant uranium joint venture interests are comprised of:

Producing: |  |  |  |
McArthur River |  |  | 69.81 | %
Key Lake |  |  | 83.33 | %
Non-producing: |  |  |  |
Cigar Lake |  |  | 50.03 | %
Inkai |  |  | 60.00 | %

Uranium 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.
Cameco previously accounted for its investment in BPLP using the equity method. As a result of the restructuring of the partnership agreement, which provides for joint control among the three major partners, Cameco began accounting for this investment as a joint venture effective November 1, 2005 [note 16].
16. Investment in BPLP
(a) Restructuring
On October 31, 2005, a new Bruce A limited partnership was formed to hold the lease for the four Bruce A reactors. Cameco was not part of this new partnership but it has maintained its existing 31.6% interest in BPLP, which retained ownership of the four Bruce B reactors. BPLP received an initial payment for the assets transferred to the Bruce A partnership which resulted in a special distribution to the partners. Cameco’s share of the special distribution was $200,000,000. The reorganization involving Bruce A triggered a loss of about $62,000,000 (Cameco’s share after tax) and resulted in amendments to the existing partnership agreement. These amendments led to joint control among the three major partners. As a result, effective November 1, 2005, Cameco has proportionately consolidated its 31.6% interest. Prior to November 1, 2005, Cameco was using the equity method to account for this investment.
(b) Fuel Supply Agreements
Cameco has entered into fuel supply agreements with BPLP for the procurement of fabricated fuel. Under these agreements, Cameco will supply uranium and conversion services and finance the purchase of fabrication services. Contract terms are at market rates and on normal trade terms. During 2005, sales of uranium and conversion services to BPLP amounted to $22,017,000 (2004 — $24,786,000), approximately 1.7% (2004 — 2.4%) of Cameco’s total revenue. At December 31, 2005, amounts receivable under these agreements totalled $26,666,000 (2004 — $20,887,000).
(c) Supplementary Information
Cameco holds a 31.6% limited partnership interest in BPLP. Prior to November 1, 2005, Cameco accounted for its interest in BPLP using the equity method. Since November 1, 2005, Cameco has proportionately consolidated its share of BPLP. For 2005, $114,000,000 of earnings before taxes was accounted for under the equity method.

17. 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 directors, 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 granted prior to 1999 expire 10 years from the date of the grant of the option.
Prior to 1999, participants were eligible to receive loans from Cameco to assist in the purchase of common shares pursuant to the exercise of options. The maximum term of the loans was 10 years from the date of the grant of the related option. The loans bear interest at a rate equivalent to the regular dividends paid on the common shares to which the loans were provided. Common shares purchased by way of a company loan are held in escrow in the account of the option holder and are pledged as security for the respective loan until the loan has been repaid in full. Outstanding loans are shown as a reduction of share capital [note 9].
The aggregate number of common shares that may be issued pursuant to the Cameco stock option plan shall not exceed 31,460,418, of which 19,613,034 shares have been issued.
Stock option transactions for the respective years were as follows:

The foregoing options have expiry dates ranging from March 10, 2006 to December 8, 2015.
CICA Handbook Section 3870, Stock-based Compensation and Other Stock-based Payments, establishes a fair value based method of accounting for stock-based compensation plans which Cameco has adopted effective January 1, 2003.
For the year ended December 31, 2005, Cameco has recorded compensation expense of $14,751,000 (2004 — $7,206,000; 2003 — $2,439,000) with an offsetting credit to contributed surplus to reflect the estimated fair value of stock options granted to employees in 2005.
Since Cameco’s stock option awards vest over three years, the compensation expense included in the determination of net income for 2005 is less than that which would have been recognized if the fair value based method had been applied to all awards since the original effective date of CICA Section 3870.
Cameco has applied the pro forma disclosure provisions of the standard to awards granted on or after January 1, 2002 but prior to January 1, 2003. The pro forma effect of awards granted prior to January 1, 2002 has not been included. The pro forma net earnings, basic and diluted earnings per share after giving effect to the grant of these options in 2002 are:

|  | 2005 |  |  | 2004 |  |  | 2003 |
Net earnings — as reported |  | $ | 217,631 |  |  | $ | 278,785 |  |  | $ | 208,163 |
Add: Stock option employee compensation expense included in reported net earnings |  |  | 14,751 |  |  |  | 7,206 |  |  |  | 2,439 |
Deduct: Total stock option employee compensation expense determined under fair value based method for all awards |  |  | (14,828 | ) |  |  | (7,810 | ) |  |  | (3,893 | )
Net earnings — pro forma |  | $ | 217,554 |  |  | $ | 278,181 |  |  | $ | 206,709 |
Pro forma basic earnings per share |  | $ | 0.63 |  |  | $ | 0.81 |  |  | $ | 0.61 |
Pro forma diluted earnings per share |  | $ | 0.60 |  |  | $ | 0.78 |  |  | $ | 0.60 |

The fair value of the options issued was determined using the Black-Scholes option-pricing model with the following assumptions:

|  | 2005 |  |  | 2004 |  |  | 2003 |

Executive Performance Share Unit (PSU), Deferred Share Unit (DSU), and Other Plans
Commencing in 2005, Cameco provides each executive officer 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, 2005, the total PSUs held by the executive was 196,200.
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. In 2005, 60% of each director’s annual retainer was paid in DSUs. In addition, on an annual basis directors can elect to receive the remaining 40% of their annual retainer and any additional fees in the form of 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, 2005, the total DSUs held by participating directors was 281,766 (2004 – 251,358).
Cameco makes annual grants of bonuses to eligible non-North American employees in the form of phantom stock options. Options under this plan are not physically granted; rather 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, 2005, the number of options held by participating employees was 443,760 (2004 – 577,800) with exercise prices ranging from $4.81 to $27.04 per share (2004 – $4.81 to $10.52) and a weighted average exercise price of $12.12 (2004 – $8.35).
Cameco has recognized the following amounts for these plans:

Performance share units |  | $ | 2,011 |  |  | $ | – |  |  | $ | – |

18. 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 dependents. 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, 2003. The next planned effective date for valuation for funding purposes of the pension benefit plans is set to be January 1, 2006. The status of the defined plans is as follows:

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, 2004. The next planned effective date for valuation for funding purposes of the pension benefit plans is set to be January 1, 2007. The status of the defined plans is as follows:

19. Goodwill
The acquisitions undertaken as part of the gold restructuring were accounted for using the purchase method whereby assets and liabilities assumed were recorded at their fair market value as of the date of acquisition [note 20]. The excess of the purchase price over such fair value was recorded as goodwill.
Cameco tests goodwill for possible impairment on an annual basis and at any other time if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. During the third quarter of 2005, Cameco completed the goodwill impairment test for all reporting units. The results of this test indicated there was no impairment.
20. Restructuring of the Gold Business
(a) Initial Public Offering
Under its initial public offering, Centerra issued 5,000,000 common shares to the public on June 30, 2004 for net proceeds of $73,625,000 after deducting the underwriter’s fees of 5%. On July 28, 2004, the underwriters to the initial public offering of Centerra exercised their over-allotment option to acquire an additional 1,875,000 shares for net proceeds of $27,609,000.
(b) Acquisition of 66.7% Interest in KGC
Pursuant to the restructuring agreement between Cameco Gold Inc. (a wholly owned subsidiary of Cameco) and Kyrgyzaltyn, Centerra acquired an additional 66.7% interest in KGC, resulting in KGC becoming a wholly owned subsidiary of Centerra. The purchase price consisted of $11,000,000 (US) in cash, the contribution of a promissory note receivable and common shares of Centerra. The acquisition was accounted for using the purchase method and the results of operations are included, as to 100%, in the consolidated financial statements from June 22, 2004. Previously, Cameco Gold Inc.’s 33.3% interest was accounted for by the proportionate consolidation method.

(c) AGR Limited (“AGR”)

| (i) |  | Acquisition of 56.2% Interest in AGR On March 5, 2002, Cameco acquired a 52.2% interest in AGR. AGR is an Australia-based exploration company whose principal asset is a 95.0% interest in the Boroo gold deposit located in Mongolia. The purchase price was financed with $12,000,000 (US) in cash and the contribution of a neighbouring property. In exchange, AGR issued 240,000,000 shares to Cameco. The acquisition was accounted for using the purchase method and the results of operations are included in Cameco’s consolidated financial statements from the effective date of the purchase.

21. Commitments and Contingencies

| (a) |  | Cameco signed a toll-conversion agreement with British Nuclear Fuels plc (BNFL) to acquire uranium UF6 conversion services from BNFL’s Springfields plant in Lancashire, United Kingdom. Under the 10-year agreement, BNFL is obligated to annually convert a base quantity of five million kgU as UO 3 to UF 6 for Cameco.
| (b) |  | A jury action was commenced by Oren Benton on November 28, 2000 in the State of Colorado, USA, against Cameco. The action claims in excess of $200,000,000 (US) for breach of contract, breach of duty of good faith and fair dealing, and tortuous interference with contractual relations and/or business expectations. Cameco’s motion to dismiss the claim was granted by Senior Judge Daniel B. Sparr by order filed November 15, 2002 and Mr. Benton’s claim was dismissed. Mr. Benton has unsuccessfully appealed this decision and his appeal to the Supreme Court of the United States was also denied.
|  |  | On October 9, 2005, Oren Benton filed a claim in Regina, Saskatchewan. The claim is similar to the action he commenced in Colorado except it does not specify the amount of damages claimed. Management is of the opinion, after review of the facts with counsel, that the claim is completely without merit and that the outcome of this action will not have a material financial impact on Cameco’s financial position, results of operations and liquidity.
| (c) |  | Cameco’s wholly owned subsidiary, Power Resources Inc. (“PRI”), and two unrelated third parties have been sued in the United States District Court for the District of Wyoming by Mountain West Mines Inc. (“MWM”). MWM claims that PRI and the other defendants owe it royalties on uranium mined in the Powder River Basin of Wyoming (which encompasses the Highland and Smith Ranch operations). PRI’s exposure consists of unpaid royalties plus interest, and a continuing royalty on uranium from its operations within the Powder River Basin of approximately 4% of the selling price. MWM has submitted an expert report claiming that the amount of unpaid royalties is $6,690,755 (US) for the period 1993 through 2003 and the amount of interest thereon is $4,153,607 (US) as of January 7, 2005. The non-jury trial for this matter had originally been scheduled to start on June 20, 2005. The presiding judge had rescheduled the trial to August 5, 2005. On April 29, 2005, a hearing was held on MWM’s motion that the Statement of Defense filed by PRI and the other defendants be struck, and the competing motion by PRI and the two other defendants that MWM’s complaint be struck. The Magistrate Judge issued a report to the presiding judge on May 27, 2005 recommending that the defendant’s motion to strike MWM’s complaint be granted. The presiding judge endorsed the report of the Magistrate Judge and issued a judgment on September 15, 2005 dismissing MWM’s claim and awarding the defendant’s legal costs. The judgment is now being appealed.
|  |  | Management is of the opinion, after review of the facts with counsel, that PRI will prevail and, therefore, this action will not have a material financial impact on Cameco’s financial position, results of operations and liquidity.
| (d) |  | On February 9, 2006, Cameco was served with a Statement of Claim issued out of the Ontario Superior Court of Justice by Rio Algom Limited (“Rio Algom”). Cameco is named in the Statement of Claim as a co-defendant with The Attorney General of Canada. In the Statement of Claim, Rio Algom is claiming against Cameco and The Attorney General of Canada $75,000,000 in damages plus costs and pre-judgment interest. The claim relates to tailings management costs incurred by Rio Algom for the now defunct uranium mines in the Elliott Lake area of northern Ontario. Rio Algom claims it is entitled to recover these costs under uranium sales agreements entered into in the 1950s by Rio Algom’s predecessors and Eldorado Nuclear Mining and Refining Ltd., a federal crown corporation. Rio Algom claims Cameco is now responsible for Eldorado Nuclear Mining and Refining Ltd.’s historical liabilities.
| (d) |  | Management is of the opinion, after review of the facts with counsel, that the claim is completely without merit and that the outcome of this action will not have a material financial impact on Cameco’s financial position, results of operations and liquidity.
| (e) |  | In the fourth quarter, KGC entered into contracts to purchase plant and equipment for $62,200,000 (US). These commitments are expected to be settled in 2006.
| (f) |  | Annual supplemental rents of $26,000,000 (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 $13,000,000 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.
| (g) |  | 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 2004 to 2018:

| i) |  | Licensing assurances to Canadian Nuclear Safety Commission of up to $133,300,000. At December 31, 2005, Cameco’s actual exposure under these assurances was $23,700,000.
| ii) |  | Guarantees to customers under power sales agreements of up to $166,700,000. At December 31, 2005, Cameco’s actual exposure under these guarantees was $102,200,000.
| iii) |  | Termination payments to OPG pursuant to the lease agreement of $58,300,000.

2010 |  |  | 114 |
Thereafter |  |  | 413 |
Total |  | $ | 1,056 |

22. Financial Instruments
The majority of revenues are derived from the sale of uranium products. Cameco’s 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 inventory levels, and political and economic conditions in uranium producing and consuming countries. Revenue from gold operations is largely dependent on the market price of gold, which can be affected by political and economic factors, industry activity and the policies of central banks with respect to their levels of gold held as reserves. Financial results are also impacted by changes in foreign currency exchange rates and other operating risks.
To hedge risks associated with fluctuations in the market price for uranium, Cameco seeks to maintain a portfolio of uranium sales contracts with a variety of delivery dates and pricing mechanisms that provide a degree of protection from price volatility. Cameco enters into forward sales contracts to establish a price for future deliveries of US dollars. Net realized gains (losses) on contracts designated as hedges are recorded as deferred revenues (deferred charges) and recognized in earnings when the related hedged transactions occur.
Financial assets that are subject to credit risks include cash and securities, accounts receivable and commodity and currency instruments. Cameco mitigates credit risk on these financial assets by holding positions with a variety of large creditworthy institutions. Sales of uranium, with short payment terms, are made to customers that management believes are creditworthy.
Except as disclosed below, the fair market value of Cameco’s financial assets and financial liabilities approximates net book value as a result of the short-term nature of the instrument or the variable interest rate associated with the instrument.
BPLP is exposed to changes in electricity prices associated with an open spot market for electricity in Ontario. To hedge the commodity price risk exposure associated with changes in the price of electricity, BPLP enters into various energy and related sales contracts. These instruments have terms ranging from 2005 to 2008. At December 31, 2005, the mark-to-market loss on these sales contracts was $37,708,000.
Currency
At December 31, 2005, Cameco had $1,132,000,000 (US) in forward contracts at an average exchange rate of $1.25 and €32,450,000 at an average exchange rate of $1.20. The foreign currency contracts are scheduled for use as follows:

(Millions) |  | US |  |  | Rate |  |  | Cdn |  |  | Euro |  |  | Rate |  |  | US |
2006 |  | $ | 467 |  |  |  | 1.29 |  |  | $ | 602 |  |  | € | 9 |  |  |  | 1.19 |  |  | $ | 11 |
2007 |  |  | 370 |  |  |  | 1.24 |  |  |  | 458 |  |  |  | 11 |  |  |  | 1.20 |  |  |  | 13 |
2008 |  |  | 195 |  |  |  | 1.21 |  |  |  | 236 |  |  |  | 7 |  |  |  | 1.20 |  |  |  | 8 |
2009 |  |  | 100 |  |  |  | 1.18 |  |  |  | 118 |  |  |  | 5 |  |  |  | 1.20 |  |  |  | 6 |
Total |  | $ | 1,132 |  |  |  | 1.25 |  |  | $ | 1,414 |  |  | € | 32 |  |  |  | 1.20 |  |  | $ | 38 |

These positions consist entirely of forward sales contracts. The average exchange rate reflects the original spot prices at the time the contracts were entered into and includes deferred revenue. The realized exchange rate will depend on the forward premium (discount) that is earned (paid) as contracts are utilized.
At December 31, 2005, Cameco’s net mark-to-market gain on these foreign currency instruments was $36,600,000 (Cdn).

(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 2005, revenues from one customer of Cameco’s uranium and conversion segments represented approximately $134,600,000 (16%) of Cameco’s total revenues. In 2004, revenues from one customer of Cameco’s uranium and conversion segments represented approximately $86,500,000 (12%) of Cameco’s total revenues. In 2003, revenues from one customer of Cameco’s uranium and conversion segments represented approximately $97,000,000 (14%) of total revenue. 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 2005, electricity revenues from one customer of BPLP represented approximately 11% of BPLP’s total revenues.

Cash provided by financing |  | $ | 101,202 |  |  | $ | 54,014 |  |  | $ | 251,321 |

(d) A description of certain significant differences between Canadian GAAP and US GAAP follows:

| (i) |  | Writedown of Mineral Properties
|  |  | Under both Canadian and US GAAP, property, plant and equipment must be assessed for potential impairment. As of 2003, there was no longer any difference in the calculation of an impairment loss between Canadian and US GAAP. However, as a result of previous differences in the amounts of impairment losses recognized under US and Canadian GAAP, there is a difference in the amount of depreciation and depletion charged to earnings.
| (ii) |  | Mineral Property Costs
|  |  | Consistent with Canadian GAAP, Cameco defers costs related to mineral properties once the decision to proceed to development has been made. Under US GAAP, these costs are expensed until such time as a final feasibility study has confirmed the existence of a commercially mineable deposit. In 2005 and 2004, there were no differences in accounting for mineral property development costs. In 2003, $7,218,000 was expensed under US GAAP. In addition, since the carrying value of the mineral property is different under US GAAP, interest capitalization is impacted. Accordingly, an adjustment has been made to reduce capitalized interest by $1,760,000 (2004 – $1,614,000; 2003 – nil). Prior to 2004, the mineral property costs expensed under US GAAP included a provision for loan impairment totalling $12,642,000. Due to the recognition of reserves and the completion of a final feasibility study, Cameco was able to demonstrate the loan to be recoverable and reversed the impairment provision in 2004.
| (iii) |  | Pre-Operating Costs
|  |  | Under Canadian GAAP, pre-operating costs incurred during the commissioning phase of a new project are deferred until commercial production levels are achieved, subject to time limitations. Under US GAAP, such costs are expensed as incurred as required by AICPA Statement of Position 98-5, Reporting on the Cost of Start-Up Activities. McArthur River commercial production commenced March 1, 2000 for US GAAP and November 1, 2000 for Canadian GAAP. Differences in capitalized costs are amortized over the estimated lives of the assets to which they relate. During 2004, $1,048,000 (2003 – $17,917,000) of costs related to the restart of two nuclear reactors at BPLP were considered to be start-up costs required to be expensed under US GAAP. As a result of expensing these start-up costs, there is a difference in the capital costs recognized under Canadian and US GAAP. Accordingly, an adjustment has been made to reduce the amount of depreciation charged to earnings by $2,329,000 (2004 – $2,445,000; 2003 – nil). In 2005, the BPLP agreement was restructured resulting in the disposition of certain assets and recognition of a loss. Under US GAAP, the carrying value of these assets was less than under Canadian GAAP. Accordingly, the pre-tax loss has been reduced by $22,820,000.

| (iv) |  | Hedges and Derivative Instruments
|  |  | Under US GAAP, all derivative instruments are recognized on the balance sheet as either assets or liabilities measured at fair value. Changes in the fair value of derivatives are recognized in earnings unless specific hedge criteria are met to qualify as a cash flow hedge. Changes in the fair value of derivatives that qualify as fair value hedges, are recognized in earnings in the same period as the hedged items. Changes in the fair value of the effective portion of a cash flow hedge are deferred in other comprehensive income with any ineffectiveness of the hedge recognized immediately on the statement of earnings. Prior to 2004, forward points were included in the assessment of hedge effectiveness for Canadian GAAP purposes and excluded for US GAAP purposes. The cumulative impact of this difference was $16,042,000 at December 31, 2003 of which $1,765,000 was recognized in 2005 (2004 – $12,104,000).
|  |  | For amounts included in the balance sheet as accumulated other comprehensive income as at December 31, 2005, a gain of $21,883,000 (after tax) relates to the hedging of foreign exchange risk. Of these amounts, $8,794,000 (after tax) would be recorded in earnings during 2006 if market conditions remained unchanged. The impact on other comprehensive income for 2005 is a loss of $14,583,000 (2004 – gain of $38,814,000; 2003 – gain of $26,107,000). BPLP also has certain derivative instruments that qualify for hedge accounting. For amounts included in the balance sheet as accumulated other comprehensive income as at December 31, 2005, a loss of $24,887,000 (after tax) relates to the hedging of electricity price risk. Of this amount, $16,520,000 (after tax) would be recorded in earnings for 2006 if market conditions remained unchanged. The impact on other comprehensive income for hedge accounting for 2005 is a loss of $22,165,000 (2004 – loss of $6,123,000; 2003 – gain of $3,401,000). Prior to August 2003, certain BPLP energy contracts did not qualify for hedge accounting under US GAAP as the documentation required for hedge accounting was not contemplated at the time of entering into the contracts. Accordingly, changes in the fair value of these contracts were charged to US GAAP earnings. Under Canadian GAAP, hedge accounting was applied prior to August 2003, resulting in differences to be recognized in future periods. As a result of this past difference in hedge accounting treatment, $259,000 was recognized in earnings in 2005 (2004 – $618,000; 2003 – $3,979,000).
| (v) |  | Cumulative Translation Account
|  |  | Under US GAAP, exchange gains and losses arising from the translation of our net investments in foreign operations are included in comprehensive income. In addition, exchange gains and losses of any foreign currency debt designated as hedges of those net investments are included in comprehensive income. Cumulative amounts are included in accumulated other comprehensive income on the balance sheet.
| (vi) |  | Cumulative Effect of a Change in Accounting Policy
|  |  | In 2001, the FASB issued Statement 143, Accounting for Asset Retirement Obligations, which addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. The standard applies to legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and use of the asset. Statement 143 requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The fair value is added to the carrying amount of the associated asset. The liability is accreted at the end of each period through charges to operating expenses. For Canadian GAAP, the effect of the change in policy on the balance sheet at December 31, 2002 is to increase property, plant and equipment by $22,827,000, future income taxes by $7,646,000, liabilities by $4,498,000 and opening retained earnings by $10,683,000. Under US GAAP, the adjustment of $10,683,000 is recorded in income in 2003 as a cumulative effect of a change in accounting policy.
| (vii) |  | Available-for-Sale Securities
|  |  | Under Canadian GAAP, portfolio investments are accounted for using the cost method. Under US GAAP, portfolio investments classified as available-for-sale securities are carried at market values with unrealized gains or losses reflected as a separate component of shareholders’ equity and included in comprehensive income. Cameco’s investments in Energy Resources of Australia Ltd, Batavia Mining Ltd. (formerly Menzies Gold NL), Tenke Mining Corp., Maudore Minerals Ltd. (formerly Maude Lake Exploration Ltd.), and Golden Band Resources Inc. are classified as available for sale. The investment in Energy Resources of Australia Ltd was sold in 2005 and the investments in Batavia Mining Ltd. and Tenke Mining Corp. were sold in 2004. The fair market value of the owned investments at December 31, 2005 is $887,000 (2004 – $79,785,000). The cumulative unrealized gain at December 31, 2005 is $107,000 (2004 – $60,713,000).

| (e) |  | Investment in BPLP
|  |  | Under Canadian GAAP, Cameco accounts for its interest in BPLP by the proportionate consolidation method. Under US GAAP, Cameco is required to equity account for its investment and record in earnings its proportionate share of their net earnings measured in accordance with US GAAP.
| (f) |  | Stock-Based Compensation
|  |  | Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation, establishes financial accounting and reporting standards for stock-based employee compensation plans. This statement defines a fair value based method of accounting for employee stock options. However, it also allows an entity to continue to measure compensation cost for those plans using the intrinsic value based method of accounting prescribed by APB Opinion No. 25, which is similar to the method applied under Canadian GAAP and followed by Cameco prior to 2003. For periods prior to adoption, companies that continue to follow the intrinsic value based method must disclose pro forma earnings and earnings per share information under the fair value method. Cameco adopted the fair value method of accounting for employee stock options with retroactive effect to January 1, 2003. Pursuant to transitional rules related to accounting for stock-based compensation under Canadian and US GAAP, Cameco chose to record compensation expense for all employee stock options granted on or after January 1, 2003 with a corresponding increase to contributed surplus. Compensation expense for options granted during 2003 and beyond is determined based on the estimated fair values at the time of grant, the cost of which is recognized over the vesting periods of the respective options. Cameco has applied the pro forma disclosure provisions of the standard to awards granted prior to January 1, 2003. The pro forma net earnings, basic and diluted earnings per share after giving effect to the grant of these options are:

|  | 2005 |  |  | 2004 |  |  | 2003 |
Net earnings for the year in accordance with US GAAP as calculated above |  | $ | 233,240 |  |  | $ | 283,192 |  |  | $ | 216,119 |
Effect of recording compensation expense under stock options plans |  |  | (77 | ) |  |  | (604 | ) |  |  | (2,027 | )
Pro forma net earnings after application of SFAS 123 |  | $ | 233,163 |  |  | $ | 282,588 |  |  | $ | 214,092 |
Pro forma basic net earnings per common share after application of SFAS 123* |  | $ | 0.67 |  |  | $ | 0.82 |  |  | $ | 0.64 |
Pro forma diluted net earnings per common share after application of SFAS 123* |  | $ | 0.65 |  |  | $ | 0.79 |  |  | $ | 0.62 |

* |  | Per share amounts for 2004 and 2003 have been restated to reflect the stock split [note 9].

|  | In calculating the foregoing pro forma amounts, the fair value of each option grant was estimated as of the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:

|  | 2002 |  |  | 2001 |
Dividend |  | $ | 0.09 |  |  | $ | 0.09 |
Expected volatility |  |  | 20.0 | % |  |  | 39.6 | %
Risk-free interest rate |  |  | 5.0 | % |  |  | 5.5 | %
Expected life of option |  | 5 years |  | 8 years
Expected forfeitures |  |  | 17.0 | % |  |  | 20.0 | %
Weighted average grant date fair values |  | $ | 1.81 |  |  | $ | 2.27 |

| (g) |  | New Accounting Pronouncements
|  |  | In March 2005, the FASB issued Financial Interpretation 47, Accounting for Conditional Asset Retirement Obligations (FIN 47). FIN 47 clarifies that the term “conditional asset retirement obligation” as used in FASB Statement No. 143, Accounting for Asset Retirement Obligations, refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and (or) method of settlement. Thus, the timing and (or) method of settlement may be conditional on a future event. Accordingly, an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated. FIN 47 also clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. FIN 47 is effective no later than the end of fiscal years

|  |  | ending after December 15, 2005. The adoption of this statement did not have a material impact on Cameco’s consolidated financial statements. In March 2005, the Emerging Issues Task Force (EITF) reached a consensus on Issue No. 04-6, Accounting for Stripping Costs Incurred during Production in the Mining Industry. In the mining industry, companies may be required to remove overburden and other mine waste materials to access mineral deposits. The EITF concluded that the costs of removing overburden and waste materials, often referred to as “stripping costs”, incurred during the production phase of a mine are variable production costs that should be included in the costs of the inventory produced during the period that the stripping costs are incurred. Issue No. 04-6 is effective for the first reporting period in fiscal years beginning after December 15, 2005, with early adoption permitted. Cameco does not expect the adoption of this statement will have a material impact on its consolidated financial statements.
|  |  | In June 2005, the FASB issued Statement 154, Accounting Changes and Error Corrections, which replaces APB Opinion 20 and FASB Statement 3. Statement 154 changes the requirements for the accounting and reporting of a change in accounting principle. Opinion 20 previously required that most voluntary changes in accounting principle be recognized by including the cumulative effect of the new accounting principle in net income of the period of the change. Statement 154 now requires retrospective application of changes in accounting principle to prior period financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. The Statement is effective for fiscal years beginning after December 15, 2005. Cameco does not expect the adoption of this statement will have a material impact on its consolidated financial statements.

26. Subsequent Events

| (a) |  | On February 1, 2006, Cameco announced it had completed the acquisition of a 100% interest in Zircatec Precision Industries, Inc. for $108,000,000, subject to closing adjustments. Zircatec’s primary business is manufacturing nuclear fuel bundles for sale to companies that generate electricity for Candu reactors. Cameco used cash to fund this acquisition that is expected to be moderately accretive to cash flow and earnings in 2006, assuming there is no significant change to existing revenue and costs.
| (b) |  | On January 31, 2006, the board of directors of Cameco approved a split of the company’s outstanding common shares on a two-for-one basis. The stock split was effected in the form of a stock dividend of one additional common share for each share owned by shareholders of record at the close of business on February 17, 2006.

Summary of Significant Accounting Policies
The consolidated financial statements are prepared by management in accordance with Canadian generally accepted accounting principles and, except as described in note 25, conform in all material respects with accounting principles generally accepted in the United States. 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.
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.
Cash
Cash consists 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.
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.
Supplies
Consumable supplies and spares are valued at the lower of cost or replacement value.
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 carried at cost or at cost less amounts written off to reflect a decline in value that is other than temporary.
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.
Non-Producing Properties
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 will be depleted by charges against earnings from future mining operations. 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 life 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.
Property Evaluations
Cameco reviews the carrying values of its properties 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.
Goodwill
Acquisitions are accounted for using the purchase method whereby acquired assets and liabilities are recorded at fair value as of the date of acquisition. The excess of the purchase price over such fair value is recorded as goodwill. Goodwill is assigned to assets and is not amortized.
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 if realization is considered more likely than not.
Capitalization of Interest
Interest is capitalized on expenditures related to construction or development projects actively being

prepared for their intended use. Capitalization is discontinued when the asset enters commercial operation or development ceases.
Depreciation and Depletion
Conversion services assets, mine buildings, equipment and mineral properties are depreciated or depleted according to the unit-of-production method. This method allocates the costs of these assets to each accounting period. For conversion 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’ economically recoverable proven and probable ore reserves which are recovered during the period.
Other assets are depreciated according to the straight-line method based on estimated useful lives, which generally range from three to 10 years.
Nuclear generating plants are depreciated according to the straight-line method based on the lower of useful life and remaining lease term.
Research and Development and Exploration Costs
Expenditures for applied research and technology related to the products and processes of Cameco and expenditures for geological exploration programs are charged against earnings as incurred.
Environmental Protection and Reclamation Costs
The fair value of the liability for an asset retirement obligation is recognized in the period incurred. The fair value is added to the carrying amount of the associated asset and depreciated over the asset’s useful life. The liability is accreted over time 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 and cost estimates. Expenditures relating to ongoing environmental programs are charged against earnings as incurred or capitalized and depreciated depending on their relationship to future earnings.
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 obligation 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 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 service life of the plan participants.
Stock-Based Compensation
Cameco has four stock-based compensation plans that are described in note 17. These encompass a stock option plan, a preferred share unit plan, a deferred share unit plan and a phantom stock option plan.
Options granted under the stock option plan on or after January 1, 2003 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 vesting period. For options granted prior to January 1, 2003, no compensation expense was recognized when the stock options were granted. Any consideration received on exercise of stock options is credited to share capital.
Deferred share units, preferred share units and phantom stock options are amortized over their vesting periods and re-measured at each reporting period, until settlement, using the quoted market value.
Revenue Recognition
Cameco supplies uranium concentrates and uranium conversion services to utility customers. Third-party fabricators process Cameco’s products into fuel for use in nuclear reactors.
Cameco recognizes revenue on the sale of its nuclear products when persuasive evidence of an arrangement exists, 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 conversion 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.
Cameco records revenue on the sale of gold when title passes and delivery is effected.
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.
Amortization of Financing Costs
Debt discounts and issue expenses associated with long-term financing are deferred and amortized over the term of the issues to which they relate.
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.
The United States dollar is considered the functional currency of most of Cameco’s uranium and gold 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 cumulative translation account component of shareholders’ equity. Exchange gains or losses arising from the translation of foreign debt and preferred securities designated as hedges of a net investment in foreign operations are also recorded in the cumulative translation account component of shareholders’ equity. These adjustments are not included in earnings until realized through a reduction in Cameco’s net investment in such operations.
Derivative Financial Instruments and Hedging Transactions
Cameco uses derivative financial and commodity instruments to reduce exposure to fluctuations in foreign currency exchange rates, interest rates and commodity prices. 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. This 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 hedge’s 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. Gains and losses related to hedging items are deferred and recognized in the same period as the corresponding hedged items. If derivative financial instruments are closed before planned delivery, gains or losses are recorded as deferred revenue or deferred charges and recognized on the planned delivery date. In the event a hedged item is sold, extinguished or matures prior to the termination of the related hedging instrument, any realized or unrealized gain or loss on such derivative instrument is recognized in earnings.
BPLP uses various energy and related sales contracts to reduce exposure to fluctuations in the price of electricity in Ontario. Gains or losses on hedging instruments are recognized in earnings over the term of the contract when the underlying hedged transactions occur. All energy contracts are designated as hedges of BPLP’s electricity sales.
Earnings Per Share
Earnings per share are calculated using the weighted average number of paid common shares outstanding.
The calculation of diluted earnings per share assumes that outstanding options and warrants 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.
