Notes to the Consolidated Financial Statements

(in millions of US dollars except share and per-share amounts)

(unaudited)

1. Significant Accounting Policies

Basis of Presentation

With its subsidiaries, Potash Corporation of Saskatchewan Inc. ("PCS") - together known as "PotashCorp" or "the company" except to the extent the context otherwise requires - forms an integrated fertilizer and related industrial and feed products company. The company's accounting policies are in accordance with accounting principles generally accepted in Canada ("Canadian GAAP"). These policies are consistent with accounting principles generally accepted in the United States ("US GAAP") except as outlined in Note 15. The accounting policies used in preparing these interim consolidated financial statements are consistent with those used in the preparation of the 2003 annual consolidated financial statements, except as disclosed in Note 2.

These interim consolidated financial statements do not include all disclosures normally provided in annual consolidated financial statements and should be read in conjunction with the most recent annual consolidated financial statements. In management's opinion, the unaudited consolidated financial information includes all adjustments (consisting solely of normal recurring adjustments) necessary to present fairly such information. Interim results are not necessarily indicative of the results expected for the fiscal year.

In 2003, the company approved plans to restructure certain operations. Those plans required significant estimates to be made of: (i) the recoverability of the carrying value of certain assets based on their capacity to generate future cash flows, and (ii) employee termination, contract termination and other exit costs. Because restructuring activities are complex processes that can take several months to complete, they involve periodically reassessing estimates. As a result, the company may have to change originally reported estimates as actual payments are made or activities are completed. Please refer to Note 5 and Note 6.

Principles of Consolidation

The consolidated financial statements include the accounts of the company and its principal operating subsidiaries:

- PCS Sales (Canada) Inc.

- PCS Joint Venture, L.P.
- PCS Sales (USA), Inc.
- PCS Phosphate Company, Inc.
- PCS Purified Phosphates
- White Springs Agricultural Chemicals, Inc.
- PCS Nitrogen, Inc.

Recent Accounting Pronouncements

In June 2003, the Canadian Institute of Chartered Accountants ("CICA") issued Accounting Guideline 15 ("AcG-15"), "Consolidation of Variable Interest Entities". AcG-15 is harmonized with US GAAP and provides guidance for applying the principles in CICA Section 1590, "Subsidiaries" to those entities

Table of Contents

(defined as Variable Interest Entities ("VIEs")) in which either the equity at risk is not sufficient to permit that entity to finance its activities without additional subordinated financial support from other parties, or equity investors lack voting control, an obligation to absorb expected losses or the right to receive expected residual returns. AcG-15 requires consolidation by a business of VIEs in which it is the primary beneficiary. The primary beneficiary is defined as the party that has exposure to the majority of the expected losses and/or expected residual returns of the VIE. The CICA has recently issued a draft guideline of proposed amendments to AcG-15 in an effort to clarify certain issues. The amended guideline is expected to be effective for all annual and interim periods beginning on or after November 1, 2004. The company is currently reviewing the proposed changes to the guideline to determine the potential impact, if any, on its consolidated financial statements.

In June and July, 2004, the CICA approved re-exposure drafts of proposed
Section 3855, "Financial Instruments - Recognition and Measurement", and
Section 3865, "Hedges". The CICA has confirmed that mandatory implementation of standards developed from the re-exposure drafts will be for interim and annual financial statements relating to years commencing on or after October 1, 2005. The CICA has also approved, subject to written ballot, a proposed new
Section 1530, "Comprehensive Income". Companies will not be permitted to apply
Section 1530 until Sections 3855 and 3865 are finalized. The re-exposure drafts are intended to increase harmonization with US GAAP.

In July 2004, the CICA proposed, subject to comments received following exposure, to amend Section 3500, "Earnings per Share", to conform to recent corresponding amendments proposed by the US Financial Accounting Standards Board ("FASB") and to those adopted by the International Accounting Standards Board. The CICA expects to issue its proposals in the fourth quarter of 2004 with an effective date for interim and annual periods relating to fiscal years beginning on or after January 1, 2005.

2. Changes in Accounting Policy

Sources of GAAP

Effective January 1, 2004, the company prospectively adopted new accounting requirements of the CICA as issued in Section 1100, "Generally Accepted Accounting Principles". This section establishes standards for financial reporting in accordance with GAAP and provides guidance on sources to consult when selecting accounting policies and determining appropriate disclosures when a matter is not dealt with explicitly in the primary sources of GAAP. In light of the new Section 1100 provisions, the company reviewed the application of its accounting policies and changed the consolidated financial statement presentation of sales revenue, freight costs and transportation and distribution expenses, without any effect on gross margin or net income. All comparative information has been appropriately reclassified.

In prior years, the company reported sales revenues (net of discounts, and including amounts recoverable from customers for freight, transportation and distribution) net of related freight, transportation and distribution expenses. The company now reports sales revenues (net of discounts, and including amounts recoverable from customers for freight, transportation and distribution), freight costs, and transportation and distribution expenses as separate line items on the Consolidated Statements of Operations and Retained Earnings.

Asset Retirement Obligations

On January 1, 2004, the company adopted CICA Section 3110, "Accounting for Asset Retirement Obligations", which requires the company to record an asset and related liability for the costs associated with the retirement of long-lived tangible assets when a legal liability to retire such assets exists. This includes obligations incurred as a result of acquisition, construction, or normal operation of a long-lived asset. The provisions of Section 3110 require the asset retirement obligation to be recorded at fair value at the time the liability is incurred. Accretion expense is recognized as an operating expense using the credit-adjusted risk-free interest rate in effect when the liability was recognized. The associated asset retirement obligations are capitalized as part of the carrying amount of the long-lived asset and depreciated over the estimated remaining

useful life of the asset. The company has recorded asset retirement obligations primarily associated with certain closure, reclamation, and restoration costs for its potash and phosphate operations.

The adoption of Section 3110 did not have a significant effect on the results of operations or financial position of the company. Had the provisions of Section 3110 been applied as of January 1, 2003, the pro forma effects for the year ended December 31, 2003 on net loss would not have been material. As required under the standard, the company will make periodic assessments as to the reasonableness of its asset retirement obligation estimates and revise those estimates accordingly. The respective asset and liability balances will be adjusted, which will correspondingly increase or decrease the amounts expensed in future periods.

Hedging Relationships

Effective January 1, 2004, the company adopted CICA Accounting Guideline 13, "Hedging Relationships". This guideline sets out the criteria that must be met in order to apply hedge accounting for derivatives and is based on many of the principles outlined in the US standards relating to derivative instruments and hedging activities. Specifically, the guideline provides detailed guidance on the identification, designation, documentation and effectiveness of hedging relationships, for purposes of applying hedge accounting, and the discontinuance of hedge accounting. Income and expenses on derivative instruments designated and qualifying as hedges under this guideline are recognized in earnings in the same period as the related hedged item. Ineffective hedging relationships and hedges not designated in a hedging relationship are carried at fair value on the Consolidated Statement of Financial Position, and subsequent changes in their fair value are recorded in earnings. The adoption of this accounting guideline did not have a material impact on the consolidated financial statements.

3. Inventories

Finished product $ 165.7 $ 160.7 Materials and supplies 104.8 108.0 Raw materials 43.8 54.1 Work in process 72.4 72.4
$ 386.7 $ 395.2

4. Long-term Debt

In January and February 2004, the company entered into interest rate swap contracts designated as fair value hedges that effectively converted a notional amount of $300.0 of fixed rate debt (due 2011) into floating rate debt based on six-month US dollar LIBOR rates. Net settlements on the swap instruments are recorded as adjustments to interest expense. The company did not enter into any interest rate swap contracts in 2003.

5. Provision for Plant Shutdowns

Memphis and Geismar Nitrogen Operations - 2003

In June 2003, the company indefinitely shut down its Memphis, Tennessee plant and suspended production of ammonia and nitrogen solutions at its Geismar, Louisiana facilities due to high US natural gas costs and low product margins. The plants have not been re-started since that time.

The company determined that all employee positions pertaining to the affected operations would be eliminated and recorded $4.8 in connection with costs of special termination benefits in the third quarter of 2003. The number of employees terminated as a result of the shutdowns was 187, of which 186 had left the company as of June 30, 2004. The company has made payments relating to the terminations totaling $4.0. All

Table of Contents

remaining workforce reduction costs pertaining to the 187 employees are expected to be paid by December 31, 2004.

In connection with the shutdowns, management had determined that the carrying amounts of the long-lived assets at the Memphis and Geismar nitrogen facilities were not fully recoverable, and an impairment loss of $101.6, equal to the amount by which the carrying amount of the facilities' asset groups exceeded their respective fair values, was recognized. Of the total impairment charge, $100.6 related to property, plant and equipment and $1.0 related to other assets. As part of its review, management also wrote-down certain parts inventories at these plants in the amount of $12.4.

In addition to the costs described above, management expects to incur other shutdown-related costs of approximately $11.1 and nominal annual expenditures for site security and other maintenance costs. These amounts have not been recorded in the consolidated financial statements as of June 30, 2004. Such costs will be recognized and recorded in the period in which they are incurred.

Kinston Phosphate Feed Plant - 2003

The phosphate feed plant at Kinston, North Carolina ceased operations in the first quarter of 2003. In that quarter, the company recorded $0.6 for costs of special termination benefits for Kinston employees, $0.3 for parts inventory writedowns, and $1.3 for long-lived asset impairment charges. In lieu of full plant closure, the company continued to operate the facility as a warehouse. In the third quarter of 2003, company management determined that the cost of operating Kinston as a stand-alone warehouse was uneconomical. This decision triggered a further review by management of the carrying amounts of the plant's long-lived assets. As a result of this review, management determined that the carrying amounts of the long-lived assets were not recoverable, and an additional impairment charge of $2.7, equal to the amount by which the carrying amount of the plant's long-lived assets exceeded their fair value, was recognized.

No additional costs were incurred in connection with the plant shutdowns in the first half of 2004. The following table summarizes, by reportable segment, the total amount of costs incurred to date and the total costs expected to be incurred in connection with the plant shutdowns described above:

Cumulative Total Costs Costs Expected Incurred to to be Date Incurred

6. Provision for PCS Yumbes S.C.M.

2003

In November 2003, the company entered into a share purchase agreement with Sociedad Quimica y Minera de Chile S.A. ("SQM"), whereby SQM is to acquire the shares of PCS Yumbes for an aggregate purchase price of $35.0, subject to adjustments. Under the terms of the share purchase agreement, and prior to the sale closing, PCS Yumbes will continue to operate the facility and expeditiously liquidate the inventory of nitrates. All other working capital is to be fully realized or discharged (as applicable) by the company prior to the closing. It is expected that closing will occur no later than the end of 2004.

In 2003, management conducted an assessment of the recoverability of the long-lived assets of the PCS Yumbes operations. As a result of its review, management determined that the carrying amounts of PCS Yumbes' long-lived assets were not recoverable and recorded an impairment charge of $77.4, equal to the amount by which the carrying amount of the asset group exceeded fair value. Of the total impairment charge, $13.0 related to property, plant and equipment, $63.9 related to deferred pre-production costs, and $0.5 related to deferred acquisition costs. As part of the review, management also wrote-down certain non-parts inventory by $50.2 due to the need to liquidate all inventories that would not be transferred to SQM under the agreement.

The company plans to eliminate all employee positions at PCS Yumbes by December 31, 2004 and has recorded a provision of $1.8 pertaining to contractual termination benefits to be paid, primarily under Chilean law. As of June 30, 2004, 141 of the employees had left the company. The remaining 83 employees are expected to leave the company by December 31, 2004, and all remaining workforce reduction costs are expected to be paid by that date.

The company had incurred early termination penalties in respect of certain PCS Yumbes contractual arrangements. The company recorded a provision of $11.1 in the third quarter of 2003 for these contract termination costs and $0.3 remained to be paid at June 30, 2004.

2004

During the three months ended June 30, 2004, the company recorded an additional writedown of $5.9, relating primarily to certain mining machinery and equipment that will not be transferred to SQM under the terms of the agreement and that management plans to sell prior to the end of the year. As of June 30, 2004, the fair value and carrying amount of the machinery and equipment that remains to be sold was $1.5. For measurement purposes, fair value was determined in reference to market prices for similar assets.

$ 1.8 $ 5.9 $ (0.7 ) $ (5.9 ) $ 1.1

The accrued balance is included in accounts payable and accrued charges in the Consolidated Statement of Financial Position as of June 30, 2004.

7. Income Taxes

The company's consolidated income tax rate for the three month and six month periods ended June 30, 2004 approximates 33 percent (2003 - 40 percent). The decrease in rate is due primarily to the impact of Saskatchewan resource tax incentives, changes to the Canadian federal resource allowance, and the scheduled Canadian federal statutory rate reduction.

8. Net Income Per Share

Basic net income per share for the quarter is calculated on the weighted average shares issued and outstanding for the three months ended June 30, 2004 of 53,523,000 (2003 - 52,100,000). Basic net income per share for the year-to-date is calculated on the weighted average shares issued and outstanding for the six months ended June 30, 2004 of 53,433,000 (2003 - 52,094,000).

Diluted net income per share is calculated based on the weighted average shares issued and outstanding during the period, adjusted by the total of the additional common shares that would have been issued assuming exercise of all stock options with exercise prices at or below the average market price for the period. For periods in which there was a loss attributable to common shares, stock options with exercise prices at or below the average market price for the period were excluded for the calculations of diluted net loss per share, as inclusion of these securities would have been antidilutive to the net loss per share. Weighted average shares outstanding for the diluted net income per share calculation for the quarter were 54,321,000 (2003 - 52,337,000) and for the year-to-date were 54,115,000 (2003 - 52,331,000).

9. Segment Information

The company has three reportable business segments: potash, phosphate and nitrogen. These business segments are differentiated by the chemical nutrient contained in the product that each produces. Inter-segment sales are made under terms that approximate market prices.

10. Stock-Based Compensation

The company has two stock option plans. Prior to 2003, the company applied the intrinsic value based method of accounting for the plans.

Effective December 15, 2003, the company adopted the fair value based method of accounting for stock options prospectively to all employee awards granted, modified, or settled after January 1, 2003. Prospective application of the fair value method did not have an impact on the first three fiscal quarters of 2003 since the company did not grant any options during those periods. Since the company's stock option awards vest over two years, the compensation cost included in the determination of net income for the three month and six month periods ended June 30, 2004 and 2003 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, "Stock-based Compensation and Other Stock-based Payments". The following table illustrates the effect on net income and net income per share if the fair value based method had been applied to all outstanding and unvested awards in each period.

Three Months Six Months Ended June 30 Ended June 30 2004 2003 2004 2003


Net income - as reported $ 72.6 $ 29.9 $ 123.3 $ 33.1 Add: Stock-based employee compensation expense included in reported net income, net of related tax effects 2.2 - 4.4 - Less: Total stock-based employee compensation expense determined under fair value based method for all option awards, net of related tax effects (3.2 ) (3.7 ) (6.4 ) (7.4 )
Net income - pro forma(1) $ 71.6 $ 26.2 $ 121.3 $ 25.7

(1) Compensation expense under the fair value method is recognized over the vesting period of the related stock options. Accordingly, the pro forma results of applying this method may not be indicative of future results.

Basic net income per share
As reported $ 1.36 $ 0.57 $ 2.31 $ 0.64 Pro forma $ 1.34 $ 0.50 $ 2.27 $ 0.49

Diluted net income per share As reported $ 1.34 $ 0.57 $ 2.28 $ 0.63 Pro forma $ 1.32 $ 0.50 $ 2.24 $ 0.49

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

2003 2002 2001


Expected dividend $ 1.00 $ 1.00 $ 1.00 Expected volatility 27% 32% 32% Risk-free interest rate 4.06% 4.13% 4.54% Expected life of options 8 years 8 years 8 years Expected forfeitures 16% 10% 10%

The fair value of options granted in the fourth quarter of 2003 was $15.7 (2002 - $20.1).

Pension plan contributions to be paid by the company during 2004 are not expected to differ significantly from the amounts previously disclosed in the consolidated financial statements for the year ended December 31, 2003.

12. Seasonality

The company's sales of fertilizer are seasonal. Typically, the second quarter of the year is when fertilizer sales will be highest, due to the North American spring planting season. However, planting conditions and the timing of customer purchases will vary each year and sales can be expected to shift from one quarter to another.

13. Contingencies

Canpotex

PotashCorp is a shareholder in Canpotex which markets potash offshore. Should any operating losses or other liabilities be incurred by Canpotex, the shareholders have contractually agreed to reimburse Canpotex for such losses or liabilities in proportion to their productive capacity. There were no such operating losses or other liabilities during the first six months of 2004.

Mining Risk

In common with other companies in the industry, the company is unable to acquire insurance for underground assets.

Investment in APC

The terms of a shareholders agreement with Jordan Investment Company ("JIC") provide that, from October 17, 2006 to October 16, 2009, JIC may seek to exercise a put option (the "Put") to require the company to purchase JIC's remaining common shares in Arab Potash Company ("APC"). If the Put were exercised, the company's purchase price would be calculated in accordance with a specified formula based, in part, on future earnings of APC. The amount, if any, which the company may have to pay for JIC's remaining common shares if there was to be a valid exercise of the Put is not presently determinable.

Legal Matters

In 1998, the company, along with other parties, was notified by EPA of potential liability under CERCLA with respect to certain soil and groundwater conditions at a PCS Joint Venture blending facility in Lakeland, Florida and certain adjoining property. In 1999, PCS Joint Venture signed an Administrative Order on Consent with EPA pursuant to which PCS Joint Venture agreed to conduct a Remedial Investigation and Feasibility Study ("RI/FS") of these conditions. PCS Joint Venture and another party are sharing the costs of the RI/FS. PCS Joint Venture continues to assess and evaluate the nature and extent of the impacts at the site. No final determination has yet been made of the nature, timing or cost of remedial action that may be needed nor to what extent costs incurred may be recoverable from third parties.

Various other claims and lawsuits are pending against the company. While it is not possible to determine the ultimate outcome of such actions at this time, it is management's opinion that the ultimate resolution of such actions, including those pertaining to environmental matters, will not have a material adverse effect on the company's financial condition or results of operations.

14. Guarantees

The company enters into agreements in the normal course of business that may contain features which meet the definition of a guarantee. Various debt obligations (such as overdrafts, lines of credit with counterparties for derivatives, and back-to-back loan arrangements) related to certain subsidiaries have been directly guaranteed by the company under agreements with third parties. The company would be required to perform on these guarantees in the event of default by the guaranteed parties. No material loss is anticipated by reason of such agreements and guarantees. At June 30, 2004, the maximum potential amount of future (undiscounted) payments under significant guarantees provided to third parties approximated $88.4, representing the maximum risk of loss if there were a total default by the guaranteed parties, without consideration of possible recoveries under recourse provisions or from collateral held or pledged. At June 30, 2004, no subsidiary balances subject to guarantees were outstanding in connection with the company's cash management facilities, and the company had no liabilities recorded for other obligations other than subsidiary bank borrowings of approximately $5.9, which are reflected in other long-term debt and cash margin requirements of approximately $24.7 to maintain derivatives, which are included in accounts payable and accrued charges.

Refer to Note 29 of our 2003 Annual Report for a description of other guarantees relating to the company. There have been no significant changes to these guarantees during the first six months of 2004, other than the annual automatic renewal of the letter of credit posted by the company in respect of the Province of Saskatchewan's potash decommissioning and reclamation financial assurance requirements.

15. Reconciliation of Canadian and United States Generally Accepted Accounting Principles

Canadian GAAP varies in certain significant respects from US GAAP. As required by the United States Securities and Exchange Commission ("SEC"), the effect of these principal differences on the company's interim consolidated financial statements is described and quantified below. For a complete discussion of Canadian and US GAAP differences, see Note 34 to the consolidated financial statements for the year ended December 31, 2003 in our 2003 Annual Report.

Long-term investments: The company's investment in Israel Chemicals Limited ("ICL") is stated at cost. US GAAP requires that this investment be classified as available-for-sale and be stated at market value with the difference between market value and cost reported as a component of Other Comprehensive Income ("OCI").

Property, plant and equipment and goodwill: The net book value of property, plant and equipment and goodwill under Canadian GAAP is higher than under US GAAP, as past provisions for asset impairment under Canadian GAAP were measured based on the undiscounted cash flow from use together with the residual value of the assets. Under US GAAP they were measured based on fair value, which was lower than the undiscounted cash flow from use together with the residual value of the assets.

Pre-operating costs: Operating costs incurred during the start-up phase of new projects are deferred under Canadian GAAP until commercial production levels are reached, at which time they are amortized over the estimated life of the project. US GAAP requires that these costs be expensed as incurred.

Post-retirement and post-employment benefits: Under Canadian GAAP, when a defined benefit plan gives rise to an accrued benefit asset, a company must recognize a valuation allowance for the excess of the adjusted benefit asset over the expected future benefit to be realized from the plan asset. Changes in the pension valuation allowance are recognized in income. US GAAP does not specifically address pension valuation allowances, and the US regulators have interpreted this to be a difference between Canadian and US GAAP. In light of this, a difference between Canadian and US GAAP has been recorded for the effects of recognizing a pension valuation allowance and the changes therein under Canadian GAAP.

The company's accumulated benefit obligation for its US pension plans exceeds the fair value of plan assets. US GAAP requires the recognition of an additional minimum pension liability in the amount of the excess of the unfunded accumulated benefit obligation over the recorded pension benefits liability. An offsetting intangible asset is recorded equal to the unrecognized prior service costs, with any difference recorded as a reduction of accumulated OCI. No similar requirement exists under Canadian GAAP.

Foreign currency translation adjustment: The company adopted the US dollar as its functional and reporting currency on January 1, 1995. At that time, the consolidated financial statements were translated into US dollars at the December 31, 1994 year-end exchange rate using the translation of convenience method under Canadian GAAP. This translation method was not permitted under US GAAP. US GAAP required the comparative Consolidated Statements of Operations and Consolidated Statements of Cash Flow to be translated at applicable weighted-average exchange rates; whereas, the Consolidated Statements of Financial Position were permitted to be translated at the December 31, 1994 year-end exchange rate. The use of disparate exchange rates under US GAAP gave rise to a foreign currency translation adjustment. Under US GAAP, this adjustment is reported as a component of accumulated OCI.

Derivative instruments and hedging activities: Under Canadian GAAP, income and expenses on derivative instruments designated as and qualifying as effective fair value hedges or cash flow hedges are recognized in earnings in the same period as the related hedged item. Gains or losses arising from settled natural gas hedging transactions are deferred as a component of inventory until the product containing the hedged item is sold, at which time both the natural gas purchase cost and the related hedging deferral are recorded as cost of goods sold. Derivatives associated with ineffective hedging relationships and hedges not designated in a hedging relationship are carried at fair value on the Consolidated Statement of Financial Position, and subsequent changes in their fair value are recorded in earnings. In accordance with SFAS No. 133 "Accounting for Derivative Instrument and Hedging Activities" and its related interpretations and amendments under US GAAP, the company records all derivatives as either assets or liabilities on the Consolidated Statements of Financial Position and measures those instruments at fair value. For derivatives that are designated as and qualify as effective cash flow hedges, the portion of gain or loss on the derivative instrument effective at offsetting changes in the hedged item is reported as a component of accumulated OCI and reclassified into earnings as cost of goods sold when the hedged transaction affects earnings. For derivative instruments that are designated as and qualify as effective fair value hedges, the gain or loss on the derivative instrument as well as the offsetting gain or loss on the hedged item attributable to the hedged risk is recognized in earnings as interest expense in the period the changes in fair value occur. Ineffective portions of cash flow or fair value hedges are recorded in earnings in the current period. Derivatives not designated as hedging instruments are marked to market through earnings in the period the changes in fair value occur.

Freight, transportation and distribution: The company has changed its accounting policy regarding consolidated financial statement presentation of freight costs and transportation and distribution expenses under US GAAP. In prior years, the company included freight costs in cost of goods sold and transportation and distribution expenses in operating expenses under US GAAP. Effective January 1, 2004, the company discloses freight costs and transportation and distribution expenses under US GAAP as separate line items within gross margin on the Consolidated Statements of Operations and Retained Earnings. This presentation

is consistent with the new Canadian GAAP presentation described in Note 2. All comparative information has been appropriately reclassified.

Depreciation and amortization: Depreciation and amortization under Canadian GAAP is higher than under US GAAP, as a result of differences in the carrying amounts of property, plant and equipment under Canadian and US GAAP.

Comprehensive income: Comprehensive income is recognized and measured under US GAAP pursuant to SFAS No. 130 "Reporting Comprehensive Income". This standard defines comprehensive income as all changes in equity other than those resulting from investments by owners and distributions to owners. Comprehensive income is comprised of two components, net income and OCI. OCI refers to amounts that are recorded as an element of shareholders' equity but are excluded from net income because these transactions or events were attributed to changes from non-owner sources. The concept of comprehensive income does not yet exist under Canadian GAAP.

Income taxes: The income tax adjustment reflects the impact on income taxes of the US GAAP adjustments described above. Accounting for income taxes under Canadian and US GAAP is similar, except that income tax rates of enacted or substantively enacted tax law must be used to calculate future income tax assets and liabilities under Canadian GAAP; whereas only income tax rates of enacted tax law can be used under US GAAP.

The application of US GAAP, as described above, would have had the following effects on net income, net income per share, total assets and shareholders' equity:

Supplemental US GAAP Disclosures

Recent Accounting Pronouncements

In December 2003, the FASB revised FIN No. 46, "Consolidation of Variable Interest Entities", which clarifies the application of Accounting Research Bulletin No. 51 "Consolidated Financial Statements" to those entities (defined as VIEs) in which either the equity at risk is not sufficient to permit that entity to finance its activities without additional subordinated financial support from other parties, or equity investors lack voting control, an obligation to absorb expected losses or the right to receive expected residual returns. FIN No. 46 requires consolidation by a business of VIEs in which it is the primary beneficiary. The primary beneficiary is defined as the party that has exposure to the majority of the expected losses and/or expected residual returns of the VIE. FIN No. 46 was effective for the company in the first quarter, and there was no material impact on its financial position, results of operations or cash flows from adoption.

In December 2003, the SEC issued Staff Accounting Bulletin ("SAB") No. 104, "Revenue Recognition", which supersedes SAB No. 101. The primary purpose of SAB No. 104 is to rescind accounting guidance contained in SAB No. 101 and the SEC's "Revenue Recognition in Financial Statements Frequently Asked Questions and Answers" related to multiple element revenue arrangements. The changes noted in SAB No. 104 did not have a material impact on the company's consolidated financial statements.

In December 2003, the Medicare Prescription Drug Improvement and Modernization Act of 2003 (the "Act") was signed into law. The Act introduces a prescription drug benefit beginning in 2006 under Medicare (Medicare Part D) as well as a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D. At this point, the company's analysis regarding the impact of the legislation is preliminary, as it awaits guidance from various governmental and regulatory agencies concerning the requirements that must be met to obtain these cost reductions, as well as the manner in which such savings should be measured. Based on this preliminary analysis, the company expects that the legislation will eventually reduce its costs for some of its programs, and some of the company's retiree medical plans may need to be modified in order to qualify for beneficial treatment. In May

2004, FASB Staff Position No. 106-2 was issued to provide additional guidance on the accounting for the effects of the Act. The company does not expect the legislation to have a significant impact on its consolidated financial statements.

In March 2004, the FASB ratified consensuses reached by the Emerging Issues Task Force ("EITF") with respect to EITF Issue No. 03-1, "The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments". EITF Issue No. 03-1 addresses recognition, measurement and disclosure of other-than-temporary impairment evaluations for securities within the scope of SFAS 115, "Accounting for Certain Investments in Debt and Equity Securities", and equity securities that are not subject to the scope of SFAS No. 115 and are not accounted for under the equity method according to Accounting Principles Board Opinion No. 18, "The Equity Method of Accounting for Investments in Common Stock". The recognition and measurement guidance is effective for reporting periods beginning after June 15, 2004. Disclosures for cost method investments are required to be included in annual financial statements prepared for fiscal years ending after June 15, 2004. The company has determined that its practices are substantially consistent with the application guidance of EITF Issue No. 03-1; therefore, adoption is not expected to have a significant impact on its consolidated financial statements.

In March 2004, the FASB issued an exposure draft, "Share-Based Payment - an amendment of Statements No. 123 and 95" that addresses the accounting for share-based payment transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or
(b) liabilities that are based on the fair value of the enterprise's equity instruments or that may be settled by the issuance of such equity instruments. The proposal would eliminate the ability to account for share-based compensation transactions using APB Opinion No. 25, "Accounting for Stock Issued to Employees", and generally would require instead that such transactions be accounted for using a fair-value-based method. The proposal would be applied prospectively for fiscal years beginning after December 15, 2004, as if all share-based compensation awards granted, modified, or settled after December 15, 1994, had been accounted for using the fair-value-based method of accounting. The company is currently reviewing the proposal to determine the potential impact, if any, on its consolidated financial statements.

In June 2004, the FASB issued an exposure draft of a proposed Statement, "Fair Value Measurements" to provide guidance on how to measure the fair value of financial and non-financial assets and liabilities when required by other authoritative accounting pronouncements. The proposed statement attempts to address concerns about the ability to develop reliable estimates of fair value and inconsistencies in fair value guidance provided by current US GAAP, by creating a framework that clarifies the fair value objective and its application in GAAP. In addition, the proposal expands disclosures required about the use of fair value to remeasure assets and liabilities. The standard would be effective for financial statements issued for fiscal years beginning after June 15, 2005.

In July 2004, the EITF discussed Issue No. 04-6, "Accounting for Post-Production Stripping Costs in the Mining Industry". This issue addresses whether post-production stripping costs should be expensed, deferred and amortized, or capitalized as inventory costs. Diversity in practice has arisen because these stripping costs may benefit both current period production (because removal of the waste is necessary to extract the material mined in the current period), as well as benefiting future periods (because the costs facilitate access to additional minerals to be mined in the future). The EITF discussed various views and did not reach a consensus. It has asked the mining industry working group to further develop the views and make a recommendation.

Available-for-Sale Security

The company's investment in ICL is classified as available-for-sale. The fair market value of this investment at June 30, 2004 was $208.9 and the unrealized holding gain was $116.1.

Stock-based Compensation

Prior to 2003, the company applied the intrinsic value based method of accounting for its stock option plans under US GAAP. Effective December 15, 2003, the company adopted the fair value based method of

19


Table of Contents

accounting for stock options prospectively to all employee awards granted, modified or settled after January 1, 2003 pursuant to the transitional provisions of SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure". Prospective application of the fair value method did not have an impact on the first three fiscal quarters of 2003 since the company did not grant any options during those periods. Since the company's stock option awards vest over two years, the compensation cost included in the determination of net income for the three month and six month periods ended June 30, 2004 and 2003 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 SFAS No. 123, "Accounting for Stock-Based Compensation". The following table illustrates the effect on net income and net income per share under US GAAP if the fair value based method had been applied to all outstanding and unvested awards in each period.

Derivative Instruments and Hedging Activities

The company 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 attributing derivatives that are designated as cash flow hedges to floating rate assets or liabilities or forecasted transactions and attributing derivatives that are designated as fair value hedges to fixed rate assets or liabilities. The company also formally assesses, both at the inception of the hedge and on an ongoing basis, whether each derivative is highly effective in offsetting changes in cash flows or fair value of the hedged item. Fluctuations in the value of the derivative instruments are generally offset by changes in the hedged item; however, if it is determined that a derivative is not highly effective as a hedge or if a derivative is sold, expires or ceases to be a highly effective hedge, the company will discontinue hedge accounting prospectively for the affected derivative.

Cash Flow Hedges

The company has designated its natural gas derivative instruments as cash flow hedges. The company's natural gas purchase strategy is based on diversification of price for its total gas requirements. The objective is to acquire a reliable supply of natural gas feedstock and fuel on a location-adjusted, cost-competitive basis in a manner that minimizes volatility without undue risk. The company employs derivative instruments including futures, swaps and option agreements in order to manage the cost on a portion of its natural gas requirements. These instruments are intended to hedge the future cost of the committed and anticipated natural gas

20


Table of Contents

purchases primarily for its US nitrogen plants. By policy, except as specifically permitted by the company's Gas Policy Advisory Committee, the maximum period for these hedges cannot exceed five years. The company uses these instruments to reduce price risk, not for speculative purposes.

The portion of gain or loss on derivative instruments designated as cash flow hedges that are effective at offsetting changes in the hedged item is reported as a component of accumulated OCI and then is reclassified into cost of goods sold when the product containing the hedged item is sold. Any hedge ineffectiveness is recorded in cost of goods sold in the current period. During the quarter, a gain of $15.3 was recognized in cost of goods sold ($25.8 gain on a year-to-date basis). Of the deferred gains at quarter-end, approximately $43.5 will be reclassified to cost of goods sold within the next 12 months. The fair value of the company's gas hedging contracts at June 30, 2004 was $77.1. The ineffectiveness of hedges on existing derivative instruments for the quarter and year-to-date was not material to the consolidated financial statements.

Fair Value Hedges

The company primarily uses interest rate swaps to manage the interest rate mix of the total debt portfolio and related overall cost of borrowing. In January and February 2004, the company entered into interest rate swap agreements with total notional amounts of $300.0, whereby the company, over the remaining terms of the underlying notes, will receive a fixed rate payment equivalent to the fixed interest rate of the underlying note and pay a floating rate of interest that is based on six-month US dollar LIBOR. The fair value of the swaps outstanding at June 30, 2004 was a liability of $12.6. All interest rate swaps qualify for the shortcut method of hedge accounting, thus there is no ineffectiveness related to these hedges. Changes in the fair value of derivatives that hedge interest rate risk are recorded in interest expense each period. The offsetting changes in the fair values of the related debt are also recorded in interest expense. The company does not maintain any other fair value hedges.

Certain of the prior periods' figures have been reclassified to conform with the current periods' presentation.

17. Subsequent Events

On July 21, 2004, the Board of Directors of PCS approved a split of the company's outstanding common shares on a two-for-one basis. The stock split is to be 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 August 11, 2004. The company's common shares are expected to commence trading on a split basis on August 9, 2004 on the Toronto Stock Exchange and August 18, 2004 on the New York Stock Exchange. All equity-based benefit plans will be adjusted to reflect the issuance of additional shares or options due to the declaration of the stock split. All share and per-share data for future periods will reflect the stock split.

On July 21, 2004, PCS's Board of Directors also declared a quarterly cash dividend of US $0.15 per common share (on a post-split basis) payable November 15, 2004 to shareholders of record at the close of business on October 25, 2004. This amount represents a 20-percent increase in the company's quarterly cash dividend.
