INDEPENDENT AUDITORS' REPORT


To the Plan Administrator and Participants of the
PCS U.S. Employees' Savings Plan:

We have audited the accompanying statements of net assets available for benefits
of the PCS U.S. Employees' Savings Plan (the "Plan") as of December 31, 2003 and
2002, and the related statement of changes in net assets available for benefits
for the year ended December 31, 2003. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of December 31,
2003 and 2002, and the changes in net assets available for benefits for the year
ended December 31, 2003 in conformity with accounting principles generally
accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) as of December 31, 2003 is presented for the purpose of
additional analysis and is not a required part of the basic financial statements
but is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This schedule is the responsibility of the Plan's
management. Such schedule has been subjected to the auditing procedures applied
in the audit of the basic 2003 financial statements and, in our opinion, is
fairly stated in all material respects when considered in relation to the basic
financial statements taken as a whole.

PCS U.S. EMPLOYEES' SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2003 AND 2002 AND FOR THE
YEAR ENDED DECEMBER 31, 2003
--------------------------------------------------------------------------------


1.    DESCRIPTION OF PLAN

      The following description of the PCS U.S. Employees' Savings Plan (the
      "Plan") is provided for general information purposes only. Participants
      should refer to the Plan Document for more complete information.

      General--The Plan is a defined contribution plan sponsored by PCS
      Administration (USA), Inc. (the "Company") covering all employees of the
      Company, PCS Phosphate Company, Inc., PCS Sales (USA), Inc., certain
      employees of White Springs Agricultural Chemicals, Inc. and certain
      employees of PCS Nitrogen. The Employee Benefits Committee of the Company
      controls and manages the operation and administration of the Plan. The
      Plan is subject to the provisions of the Employee Retirement Income
      Security Act of 1974 ("ERISA").

      Contributions--Participants may contribute up to 50 percent of base
      compensation each year, as defined in the Plan, subject to certain
      Internal Revenue Code limitations. The Company match, which was 100
      percent of up to the first five percent of base compensation that
      participants contribute to the Plan, was eliminated as of August 1, 2003.
      Participants may also contribute amounts representing distributions from
      other qualified defined benefit or contribution plans (rollover
      contributions), which are not eligible for the Company match.

      Participant Accounts--Individual accounts are maintained for each Plan
      participant. Each participant's account is credited with the participant's
      contribution, the Company's matching contribution when applicable, and
      allocations of plan earnings, and is charged with withdrawals, an
      allocation of plan losses and administrative expenses. Allocations are
      based on participant earnings or account balances, as defined in the Plan.
      The benefit to which a participant is entitled is the benefit that can be
      provided from the participant's vested account.

      Investments--Participants direct the investment of their account balances
      and contributions into various investment options offered by the Plan. The
      Plan currently offers Potash Corporation of Saskatchewan Inc. ("PCS")
      Common Stock, twelve mutual funds and one pooled investment stable value
      fund. The U.S. Government Reserves Fund is used to maintain dividends
      distributed with the ESOP option and is not available as a
      participant-directed investment option.

      Vesting--Participants are immediately vested in their account balances.

      Participant Loans--Participants may borrow from their fund accounts up to
      a maximum amount equal to the lesser of $50,000 or 50 percent of their
      vested account balance. Loan terms range from one to five years or up to
      20 years for the purchase of a primary residence. The loans are secured by
      the balance in the participant's account and bear interest at two
      percentage points above the rate for five-year U.S. Treasury Notes on the
      last day of the preceding quarter in which the funds are borrowed. Loans
      for the purchase of a primary residence bear interest at the standard
      lending rate for 20-year fixed rate home mortgage loans. Principal and
      interest are paid ratably through monthly payroll deductions.

      Payments of Benefits--On termination of service, a participant may elect
      to receive either a lump-sum amount equal to the value of the
      participant's vested interest in his or her account; or monthly, quarterly
      or annual installments over the participant's estimated life span. Other
      forms of benefits are also provided to participants whose accounts were
      transferred from other plans. A participant may elect to receive payment
      of benefits prior to termination of service, as defined in the Plan.
      Participants may elect to receive their investment in the PCS Stock Fund
      in cash or in whole shares of PCS Common Stock. The Plan includes an ESOP
      feature with a dividend payout program whereby participants may elect to
      receive dividends paid on their vested shares of PCS Common Stock in the
      PCS Stock Fund.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Basis of Accounting--The accompanying financial statements have been
      prepared in accordance with accounting principles generally accepted in
      the United States of America.

      Use of Estimates--The preparation of financial statements in conformity
      with accounting principles generally accepted in the United States of
      America requires Plan management to make estimates and assumptions that
      affect the reported amounts of net assets available for benefits and
      changes therein. Actual results could differ from those estimates. The
      Plan utilizes various investment instruments, including mutual funds,
      pooled investment stable value fund, and common stock. Investment
      securities, in general, are exposed to various risks, such as interest
      rate, credit, and overall market volatility. Due to the level of risk
      associated with certain investment securities, it is reasonably possible
      that changes in the values of investment securities will occur in the near
      term and that such changes could materially affect the amounts reported in
      the financial statements.

      Investment Valuation and Income Recognition--The Plan's investments are
      stated at fair value. The PCS Common Stock is valued at its quoted market
      price. Shares of mutual funds are valued at quoted market prices, which
      represent the net asset value of shares held by the Plan at year-end. The
      Fidelity Managed Income Portfolio II is valued at the amount of
      participant and Company contributions plus accrued interest thereon
      (contract value). Participant loans are valued at the outstanding loan
      balances.

      The Fidelity Managed Income Portfolio II is a stable value fund that is a
      commingled pool of the Fidelity Group Trust for Employee Benefit Plans.
      The portfolio may invest in fixed interest insurance investment contracts,
      money market funds, corporate and government bonds, mortgage-backed
      securities, bond funds, and other fixed income securities. Participants
      may ordinarily direct the withdrawal or transfer of all or a portion of
      their investment at contract value. The crediting interest rates were
      4.12% and 4.64% at December 31, 2003 and 2002, respectively, which were
      based on the interest rates of the underlying portfolio of assets. The
      average yield for the year ended December 31, 2003 was 4.31%.

      Purchases and sales of securities are recorded on a trade-date basis.
      Interest income is recorded on the accrual basis. Dividends are recorded
      on the ex-dividend date.

      Management fees and operating expenses charged to the Plan for investment
      in the mutual funds are deducted from income earned on a daily basis and
      are not separately reflected. Consequently, management fees and operating
      expenses are reflected as a reduction of net appreciation (depreciation)
      in fair market value of investments for such investments.

      Administrative Expenses--Administrative expenses of the Plan are paid by
      the Plan or the Plan Sponsor, as provided in the Plan Document.

      Payment of Benefits--Benefit payments to participants are recorded upon
      distribution. There were no amounts allocated to accounts of participants
      who have elected to withdraw from the Plan but had not yet been paid at
      December 31, 2003 and 2002.

      Transfers--Along with the plan, the company also sponsors savings plans
      for certain union employees. If employees change their union status during
      the year, their account balances are transferred into the corresponding
      plan.

4.    RELATED-PARTY TRANSACTIONS

      Certain Plan investments are shares of mutual funds managed by Fidelity
      Management Trust Company ("Fidelity"). Fidelity is the trustee as defined
      by the Plan and, therefore, these transactions qualify as
      party-in-interest transactions. Fees paid by the Plan for the investment
      management services were included as a reduction of the return earned on
      each fund.

      At December 31, 2003 and 2002, the Plan held 98,281.235 shares and
      114,031.932 shares, respectively, of common stock of Potash Corporation of
      Saskatchewan, the parent company of the Plan sponsor, with a cost basis of
      $7,172,440 and $8,303,689, respectively. During the year ended December
      31, 2003, the Plan recorded dividend income of $110,700.

5.    PLAN TERMINATION

      Although it has not expressed any intention to do so, the Company has the
      right under the Plan to discontinue its contributions at any time and to
      terminate the Plan subject to the provisions set forth in ERISA. In the
      event that the Plan is terminated, participants would remain 100 percent
      vested in their accounts.

6.    FEDERAL INCOME TAX STATUS

      The Internal Revenue Service has determined and informed the Company by a
      letter dated November 13, 2001, that the Plan was designed in accordance
      with applicable Internal Revenue Code requirements. The Plan has been
      amended since receiving the determination letter. However, the Company and
      Plan administrator believe that the Plan is currently designed and being
      operated in compliance with the applicable requirements of the Internal
      Revenue Code and continues to be tax-exempt. Therefore, no provision for
      income taxes has been included in the Plan's financial statements.
