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. These unaudited interim condensed consolidated financial statements are based on International Financial Reporting Standards, as issued by the International Accounting Standards Board (“IFRS”), and have been prepared in accordance with International Accounting Standard (“IAS”) 34, “Interim Financial Reporting.” The accounting policies used in preparing these unaudited interim condensed consolidated financial statements are consistent with those used in the preparation of the company’s 2012 annual consolidated financial statements, except as described below.

These unaudited interim condensed consolidated financial statements include the accounts of PCS and its subsidiaries; however, they do not include all disclosures normally provided in annual consolidated financial statements and should be read in conjunction with the company’s 2012 annual consolidated financial statements. In management’s opinion, the unaudited interim condensed consolidated financial statements include all adjustments necessary to fairly present such information. Interim results are not necessarily indicative of the results expected for the fiscal year.

These unaudited interim condensed consolidated financial statements were authorized by the audit committee of the Board of Directors for issue on July 30, 2013.

Standards, amendments and interpretations effective and applied

The International Accounting Standards Board (“IASB”) and International Financial Reporting Interpretations Committee (“IFRIC”) have issued the following standards and amendments or interpretations to existing standards that are effective and applied.

Standard	Description	Impact
Amendments to IAS 1, Presentation of Financial Statements	Amendments require items within other comprehensive income (“OCI”) that may be reclassified to the profit or loss section of the income statement to be grouped together.	Adopted retrospectively effective January 1, 2013. The format of the company’s consolidated statements of comprehensive income has changed. Prior periods’ figures have been reclassified to conform with the current period’s presentation.
Amendments to IFRS 7, Financial Instruments: Disclosures	Issued as part of its offsetting project, addresses common disclosure requirements related to financial instruments.	Adopted retrospectively effective January 1, 2013. Applicable disclosures are included in Note 10 to these unaudited interim condensed consolidated financial statements, and will be included in the company’s 2013 annual consolidated financial statements.
IFRS 10, Consolidated Financial Statements	Builds on existing principles by identifying the concept of control as the determining factor in whether an entity should be included within the consolidated financial statements of the parent company.	Adopted retrospectively effective January 1, 2013 with no change to the company’s consolidated financial statements.
IFRS 11, Joint Arrangements	Removes a choice in accounting method and requires equity accounting for participants in joint ventures. Also focuses on the rights and obligations of an arrangement rather than its legal form.	Adopted prospectively effective January 1, 2013 with no change to the company’s consolidated financial statements.
IFRS 12, Disclosure of Interests in Other Entities	Establishes a new and comprehensive standard on disclosure requirements for all forms of interest in other entities, including subsidiaries, joint arrangements, associates and unconsolidated structured entities.	Adopted prospectively effective January 1, 2013. Applicable disclosures will be included in the company’s 2013 annual consolidated financial statements.
IFRS 13, Fair Value Measurement	Establishes a single framework for measuring fair value and introduces consistent disclosure requirements on fair value measurements.

Applicable disclosures included in Note 10 to these unaudited interim condensed consolidated financial statements, and will be included in the company’s 2013 annual consolidated financial statements.

PotashCorp 2013 Second Quarter Quarterly Report on Form 10-Q 6

Standard	Description	Impact
Amendments to IAS 19, Employee Benefits	Changes relating to the recognition, measurement, presentation and disclosure of post-employment benefits. The amendment also changes the accounting for termination benefits and short-term employment benefits, along with other minor clarifications.	Adopted prospectively effective January 1, 2013. The amendments resulted in changes in accounting policy but did not result in any material adjustments to the company’s consolidated financial statements. Previously, the company calculated interest costs on the defined benefit obligation and the expected return on plan assets, and included such amounts within employee costs in cost of goods sold and selling and administrative expenses, as applicable. The net interest cost will now be calculated on the net funded status and included in finance costs. Previously, vested past service costs were recognized immediately and unvested past service costs were amortized on a straight-line basis over the average period until the benefits became vested. All past service costs will now be recognized immediately. Actuarial gains and losses will continue to be recognized in OCI, and closed out to retained earnings each period. Required additional disclosures will be included in the company’s 2013 annual consolidated financial statements.
IFRIC 20, Stripping Costs in the Production Phase of a Surface Mine	Clarifies the requirements for accounting for stripping costs in the production phase of a surface mine.	Adopted effective January 1, 2013 with no change to the company’s consolidated financial statements.

Standards, amendments and interpretations not yet effective and not applied

The IASB and IFRIC issued the following standards and amendments or interpretations to existing standards that are not yet effective and not applied. The company does not anticipate early adoption of these standards at this time.

Standard	Description	Impact	Effective Date(1)
Amendments to IAS 32, Offsetting Financial Assets and Financial Liabilities	Issued as part of the IASB’s offsetting project, amendments clarify certain items regarding offsetting financial assets and financial liabilities.	The company is reviewing the standard to determine the potential impact, if any; however, no significant impact is anticipated.	January 1, 2014, applied retrospectively.
Amendments to IAS 36, Recoverable Amount Disclosures for Non-Financial Assets	Amendments were issued that clarify disclosure requirements for the recoverable amount of an asset or cash-generating unit.	The company is reviewing the standard to determine the potential impact, if any; however, no significant impact is anticipated.	January 1, 2014, applied retrospectively.
IFRIC 21, Levies	Provides guidance on when to recognize a liability for a levy imposed by a government.	The company is reviewing the interpretation to determine the potential impact, if any.	January 1, 2014, applied retrospectively.
IFRS 9, Financial Instruments	Initially issued guidance on the classification and measurement of financial assets. Additional guidance was issued on the classification and measurement of financial liabilities. Further, amendments were issued that will modify the requirements for transition from IAS 39 to IFRS 9.	The company is reviewing the standard to determine the potential impact, if any.	January 1, 2015, applied prospectively.

The company’s defined benefit pension and other post-retirement benefit liabilities decreased by $133, accrued pension benefit assets increased by $104 and deferred income tax liabilities increased by $87 at June 30, 2013.

The discount rate used to determine the benefit obligation for the company’s significant plans at June 30, 2013 was 4.60 percent (December 31, 2012 — 3.85 percent).

On July 24, 2013, the company’s Board of Directors authorized a share repurchase program of up to $2,000 of PotashCorp’s outstanding common shares (5 percent of its outstanding common shares) through a normal course issuer bid. The commencement of the share repurchase program is subject to regulatory approval and will be for a one-year period from the date of commencement following receipt of such approval.

Inter-segment sales are made under terms that approximate market value. The accounting policies of the segments are the same as those described in Note 1.

7. Share-Based Compensation

On May 16, 2013, the company’s shareholders approved the 2013 Performance Option Plan under which the company may, after February 19, 2013 and before January 1, 2014, grant options to acquire up to 3,000,000 common shares. Under the plan, the exercise price shall not be less than the quoted market closing price of the company’s common shares on the last trading day immediately preceding the date of the grant, and an option’s maximum term is 10 years. In general, options will vest, if at all, according to a schedule based on the three-year average excess of the company’s consolidated cash flow return on investment over weighted average cost of capital. As of June 30, 2013, options to purchase a total of 1,952,000 common shares had been granted under the plan. The weighted average fair value of options granted was $15.13 per share, estimated as of the date of grant using the Black-Scholes-Merton option-pricing model with the following weighted average assumptions:

Exercise price per option	$	43.80
Expected annual dividend per share	$	1.40
Expected volatility		50%
Risk-free interest rate		1.06%
Expected life of options		5.5 years

8. Income Taxes

A separate estimated average annual effective tax rate is determined for each taxing jurisdiction and applied individually to the interim period pre-tax income of each jurisdiction.

	Three Months Ended June 30				Six Months Ended June 30
	2013		2012		2013		2012
Income tax expense	$	245	$	304	$	471	$	464

PotashCorp 2013 Second Quarter Quarterly Report on Form 10-Q 10

Significant items to note include the following:

Ÿ In the first six months of 2013, a tax expense of $16 ($1 in the second quarter) was recorded to adjust the 2012 income tax provision.

Ÿ In second-quarter 2013, a deferred tax expense of $11 was recorded as a result of a Canadian income tax rate increase.

Ÿ In second-quarter 2012, the impairment of the company’s available-for-sale investment in Sinofert Holdings Limited (“Sinofert”) was not deductible for tax purposes.

Income tax balances within the consolidated statements of financial position were comprised of the following:

Income Tax Assets (Liabilities)	Statements of Financial Position Location	June 30, 2013			December 31, 2012
Current income tax assets:
Current	Receivables	$	78		$	124
Non-current	Other assets		126			130
Deferred income tax assets	Other assets		26			30
Total income tax assets		$	230		$	284
Current income tax liabilities:

Total income tax liabilities		$	(1,984	)	$	(1,594	)

9. Net Income per Share

Net income per share was calculated on the following weighted average number of shares:

	Three Months Ended June 30				Six Months Ended June 30
	2013		2012		2013		2012
Basic		865,991,000		858,988,000		865,526,000		858,888,000
Diluted		877,141,000		875,507,000		876,930,000		875,813,000

Diluted net income per share was calculated based on the weighted average number of shares issued and outstanding during the period, incorporating the following adjustments. The denominator was: (1) increased 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; and (2) decreased by the number of shares that the company could have repurchased if it had used the assumed proceeds from the exercise of stock options to repurchase them on the open market at the average share price for the period. For performance-based stock option plans, the

number of contingently issuable common shares included in the calculation was based on the number of shares, if any, that would be issuable if the end of the reporting period were the end of the performance period and the effect were dilutive.

Excluded from the calculation of diluted net income per share for the three and six months ended June 30, 2013 were weighted average options outstanding of 2,441,300 relating to the 2008 and 2011 Performance Option Plans, as the options’ exercise prices were greater than the average market price of common shares for the period.

10. Financial Instruments

Fair Value

Estimated fair values for financial instruments are designed to approximate amounts at which the instruments could be exchanged in a current arm’s-length transaction between knowledgeable willing parties. The valuation policies and procedures for financial reporting purposes are determined by the company’s finance department.

Presented below is a comparison of the fair value of certain financial instruments to their carrying values.

	June 30, 2013				December 31, 2012
	Carrying Amount of Liability		Fair Value of Liability		Carrying Amount of Liability		Fair Value of Liability
Long-term debt senior notes	$	3,500	$	3,868	$	3,750	$	4,284

Due to their short-term nature, the fair value of cash and cash equivalents, receivables, short-term debt, and payables and accrued charges was assumed to approximate carrying value. The company’s derivative instruments and investments in Israel Chemicals Ltd. (“ICL”) and Sinofert were carried at fair value.

The fair value of the company’s senior notes at June 30, 2013 reflected the yield valuation based on observed market prices (Level 1), which ranged from 0.83 percent to 5.05 percent (December 31, 2012 — 0.40 percent to 4.35 percent). The fair value of the company’s other long-term debt instruments approximated carrying value.

The fair value of derivative instruments that are not traded in an active market (such as natural gas swaps and foreign currency derivatives) was determined using valuation techniques. The company used a variety of methods and made assumptions that were based on market conditions existing at each reporting date. Natural gas swap valuations were based on a discounted cash flow model. The inputs used in the model included contractual cash flows based on prices for natural gas futures contracts, fixed prices and notional volumes specified by the swap contracts, the time value of money, liquidity risk, the company’s own credit risk (related to instruments in a liability position) and counterparty credit risk (related to instruments in an asset position). Certain of the futures contract prices used as inputs in the model were

supported by prices quoted in an active market and others were not based on observable market data.

For valuations that included both observable and unobservable data, if the unobservable input was determined to be significant to the overall inputs, the entire valuation was categorized in Level 3. For natural gas swaps, the primary input into the valuation model was natural gas futures prices, which were based on delivery at the Henry Hub and were observable only for up to three years in the future. The unobservable futures price range at June 30, 2013 was $4.24 to $5.59 per MMBtu (December 31, 2012 — $4.58 to $5.48 per MMBtu). Changes in the unobservable natural gas futures prices would not result in significantly higher or lower fair values as any price change would be counterbalanced by offsetting derivative positions. Interest rates used to discount estimated cash flows at June 30, 2013 were between 0.19 percent and 3.91 percent (December 31, 2012 — between 0.21 percent and 3.26 percent) depending on the settlement date.

The fair value of foreign currency derivatives was determined using quoted forward exchange rates (Level 2) at the statements of financial position dates.

Fair value of investments designated as available-for-sale was based on the closing bid price of the common shares (Level 1) as of the statements of financial position dates.

PotashCorp 2013 Second Quarter Quarterly Report on Form 10-Q 12

The following table presents the company’s fair value hierarchy for financial assets and financial liabilities carried at fair value on a recurring basis.

⁽¹⁾ During the six months ended June 30, 2013 and twelve months ended December 31, 2012, there were no transfers between Level 1 and Level 2.

⁽²⁾ During the six months ended June 30, 2013, there were no transfers into Level 3 and $1 of gains was transferred out of Level 3 into Level 2 as (due to the passage of time) the terms of certain natural gas derivatives now matured within 36 months. During the twelve months ended December 31, 2012, there were no transfers into Level 3 and $10 of losses was transferred out of Level 3 into Level 2 as (due to the passage of time) the terms of certain natural gas derivatives now matured within 36 months. Our policy is to recognize transfers at the end of the reporting period.

The following table presents the company’s fair value measurements using significant unobservable inputs (Level 3):

11. Seasonality

The company’s sales of fertilizer can be seasonal. Typically, fertilizer sales are highest in the second quarter of the year, 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 PotashCorp 2013 Second Quarter Quarterly Report on Form 10-Q

12. Contingencies and Other Matters

Canpotex

PCS is a shareholder in Canpotex Limited (“Canpotex”), which markets Saskatchewan potash offshore. Should any operating losses or other liabilities be incurred by Canpotex, the shareholders have contractually agreed to reimburse it for such losses or liabilities in proportion to each shareholder’s productive capacity.

Through June 30, 2013, there were no such operating losses or other liabilities.

Mining Risk

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

Legal and Other Matters

Significant environmental site assessment and/or remediation matters include the following:

Ÿ The company, along with other parties, has been notified by the US Environmental Protection Agency (“USEPA”) of potential liability under the US Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”) with respect to certain soil and groundwater conditions at a site in Lakeland, Florida that includes a former PCS Joint Venture fertilizer blending facility and certain surrounding properties. A Record of Decision (“ROD”) issued in September 2007 provides for a remedy that requires excavation of impacted soils and interim treatment of groundwater at a total estimated cost of $9. The soil remediation has been performed and approved by the USEPA. A Remedial Design Work Plan for the interim remedy for groundwater has been submitted to the USEPA for approval and work is expected to commence in the fourth quarter of 2013. Although PCS Joint Venture sold the Lakeland property in July 2006, PCS Joint Venture has retained the above-described remediation responsibilities and has indemnified the third-party purchaser for the costs of remediation and certain related items.

Ÿ The USEPA has identified PCS Nitrogen, Inc. (“PCS Nitrogen”) as a potentially responsible party at the Planters Property or Columbia Nitrogen site in Charleston, South Carolina. The site includes a former fertilizer blending operation, formerly owned by a company from which PCS Nitrogen acquired certain other assets. The USEPA has requested reimbursement of $3 of previously incurred response costs and the performance or financing of future site investigation and response activities from PCS Nitrogen and other named potentially responsible parties. The current owner of the Planters Property filed a complaint against PCS Nitrogen in the United States District Court for the District of South Carolina seeking environmental response costs. The district court allocated 30 percent of the liability for response costs at the site to PCS Nitrogen, as well as a proportional share of any costs that cannot be recovered from another responsible party. The United States Court of Appeals

for the Fourth Circuit affirmed the district court’s judgment on April 4, 2013. PCS Nitrogen is considering what actions are appropriate to take in response to the Fourth Circuit’s opinion. The ultimate amount of liability for PCS Nitrogen, if any, depends upon the final outcome of the litigation, the amount needed for remedial activities, the ability of other parties to pay and the availability of insurance.

Ÿ PCS Phosphate has agreed to participate, on a non-joint and several basis, with parties to an Administrative Settlement Agreement with the USEPA (“Settling Parties”) in a removal action and the payment of certain other costs associated with PCB soil contamination at the Ward Superfund Site in Raleigh, North Carolina (“Site”), including reimbursement of past USEPA costs. The removal activities commenced in August 2007 and are estimated to cost $75. PCS Phosphate is a party to ongoing CERCLA contribution and cost recovery litigation for the recovery of costs of the removal activities, and the USEPA is seeking additional investigation and remediation work at the site. At this time, the company is unable to evaluate the extent of any exposure that it may have for the matters addressed in the CERCLA litigation or as a result of the requests by the USEPA for additional work at the site.

Ÿ In 1996, PCS Nitrogen Fertilizer, L.P. (“PCS Nitrogen Fertilizer”), then known as Arcadian Fertilizer, L.P., entered into a Consent Order (the “Order”) with the Georgia Environmental Protection Division (“GEPD”) in conjunction with PCS Nitrogen Fertilizer’s acquisition of real property in Augusta, Georgia. Under the Order, PCS Nitrogen Fertilizer is required to perform certain activities to investigate and, if necessary, implement corrective measures for substances in soil and groundwater. The investigation has proceeded and the results have been presented to GEPD. Two interim corrective measures for substances in groundwater have been proposed by PCS Nitrogen Fertilizer and approved by GEPD. PCS Nitrogen Fertilizer is implementing the approved interim corrective measures but it is unable to estimate with reasonable certainty the total cost of its corrective action obligations under the Order at this time.

The company is also engaged in ongoing site assessment and/or remediation activities at a number of other facilities and sites, and anticipated costs associated with these matters are added to accrued environmental costs in the manner previously described in Note 14 to the company’s 2012 annual consolidated financial statements. This includes matters related to investigation of potential brine migration at certain of the potash sites. Based on current information, the company does not believe that its future obligations with respect to these facilities and sites are reasonably likely to have a material adverse effect on its consolidated financial position or results of operations.

PotashCorp 2013 Second Quarter Quarterly Report on Form 10-Q 14

Other significant legal matters include the following:

Ÿ The USEPA has an ongoing initiative to evaluate implementation within the phosphate industry of a particular exemption for mineral processing wastes under the hazardous waste program. In connection with this industry-wide initiative, the USEPA conducted inspections at numerous phosphate operations and notified the company of alleged violations of the US Resource Conservation and Recovery Act (“RCRA”) at its plants in Aurora, North Carolina; Geismar, Louisiana; and White Springs, Florida; and one alleged Clean Air Act (“CAA”) violation at its Geismar, Louisiana plant. The company has entered into RCRA 3013 Administrative Orders on Consent and has performed certain site assessment activities at all three plants. At this time, the company does not know the scope of corrective action, if any, that may be required. As to the alleged RCRA violations, the company continues to participate in settlement discussions with the USEPA but is uncertain if any resolution will be possible without litigation, or, if litigation occurs, what the outcome would be. At this time, it is unable to evaluate the extent of any exposure it may have in these matters. As to the alleged CAA violation, the company and the USEPA have negotiated a consent decree, pursuant to which PCS has agreed to pay a penalty of $0.2 to resolve this matter. The consent decree remains subject to public comment.

Ÿ The USEPA has pursued an initiative to evaluate compliance with the CAA at sulfuric acid and nitric acid plants. In connection with this industry-wide initiative, it has sent requests for information to numerous facilities, including the company’s plants in Augusta, Georgia; Aurora, North Carolina; Geismar, Louisiana; Lima, Ohio; and White Springs, Florida. The USEPA and the Louisiana Department of Environmental Quality have notified the company of various alleged violations of the CAA at its Geismar, Louisiana plant. In May 2012, the USEPA issued to the company’s White Springs, Florida plant a Notice of Violation alleging that certain specified projects at the sulfuric acid plants were undertaken in violation of the CAA. While the company disputes the alleged violations, in May 2013, the company reached a tentative agreement to resolve the alleged violations without admitting any liability. The tentative agreement is subject to a variety of conditions, including the approval of the company’s Board and the negotiation of acceptable final agreements. The tentative agreement involves capital improvements, process changes and penalties for the company’s sulfuric acid plants in Aurora, North Carolina; Geismar, Louisiana; and White Springs, Florida that are currently estimated to cost at least $100, but the company is uncertain if a final agreement can be concluded. If a final agreement cannot be concluded and litigation subsequently occurs, the company is uncertain what the outcome would be.

Ÿ Significant portions of the company’s phosphate reserves in Aurora, North Carolina are located in wetlands. Under the Clean Water Act, the company must obtain a permit from the US Army Corps of Engineers (the “Corps”) before mining in the wetlands. In January 2009, the Division of Water Quality of the North Carolina Department of Natural Resources issued a certification under Section 401 of the Clean Water Act that mining of phosphate in excess of 30 years from lands owned or controlled by the company, including some wetlands, would not degrade water quality (the “401 Certification”). Thereafter, in June 2009, the Corps issued the company a permit that will allow it to mine the phosphate deposits identified in the 401 Certification. Four environmental organizations (Pamlico-Tar River Foundation, North Carolina Coastal Federation, Environmental Defense Fund and Sierra Club, collectively, the “Petitioners”) challenged the 401 Certification. Petitioners exhausted their administrative appeals of the 401 Certification without success and are now pursuing an appeal in the North Carolina courts. On July 3, 2013, the Superior Court for Wake County entered an Order affirming the agency action approving the 401 Certification. Petitioners could appeal the Order to the North Carolina Court of Appeals.

Ÿ There is no certainty as to the scope or timing of any final, effective requirements to control greenhouse gas emissions in the US or Canada. Canada has withdrawn from participation in the Kyoto Protocol, and the Canadian government has announced its intention to coordinate greenhouse gas policies with the US. Although the US Congress has not passed any greenhouse gas emission control laws, the USEPA has adopted several rules to control such emissions using authority under existing environmental laws. Some Canadian provinces and US states are considering the adoption of greenhouse gas emission control requirements. In Saskatchewan, provincial regulations pursuant to the Management and Reduction of Greenhouse Gases Act, which impose a type of carbon tax to achieve a goal of a 20 percent reduction in greenhouse gas emissions by 2020 compared to 2006 levels, may become effective in 2013. None of these regulations has resulted in material limitations on greenhouse gas emissions at the company’s facilities. The company is monitoring these developments and their future effect on its operations cannot be determined with certainty at this time.

Ÿ In December 2010, the USEPA issued a final rule to restrict nutrient concentrations in surface waters in Florida to levels below those currently permitted to be discharged from the company’s White Springs, Florida plant. Projected capital costs resulting from the USEPA rule, if it becomes effective, could be in excess of $100 for White Springs, and there is no guarantee that controls can be implemented which are capable of

15 PotashCorp 2013 Second Quarter Quarterly Report on Form 10-Q

achieving compliance with the revised nutrient standards under all flow conditions. Various judicial challenges to the federal rules have been filed, including one lawsuit against the federal rule by The Fertilizer Institute (“TFI”) and White Springs. In February 2012, the United States District Court for the Northern District of Florida (“District Court”) ruled on summary judgment motions filed by the parties seeking to either vacate or uphold the USEPA rule. The District Court upheld the USEPA numeric nutrient criteria for Florida’s lakes and springs but rejected the criteria for Florida’s streams and rivers as arbitrary and capricious. In November 2012, the USEPA approved numeric nutrient criteria rules in their entirety which had been adopted by the State of Florida and filed with the USEPA in June 2012. These state rules, which have been upheld on appeal, could substitute for the federal rules. In addition, the District Court recently granted the USEPA a further stay (to November 15, 2013) of protection values for certain inland waters but upheld the current effective date (January 6, 2013) of numeric nutrient criteria for Florida lakes and springs. In March 2013, the USEPA and the State of Florida announced an Agreement in Principle and Path Forward with the goal being to make the promulgation of federal water quality standards no longer necessary in Florida. In May 2013, the Florida Legislature enacted legislation that would facilitate the USEPA’s withdrawal of its federal rules, thereby allowing the State of Florida to fully implement the adopted state rules. The USEPA is seeking to modify the previous District Court consent decree to make its provisions consistent with these recent developments. In the meantime, the company continues to monitor and evaluate actions related to both the federal and state rules. The prospects for implementation of either the federal or the state rule and the availability of the site-specific relief mechanisms under either rule are uncertain.

Ÿ Between September and October 2008, the company and PCS Sales (USA), Inc. were named as defendants in eight similar antitrust complaints filed in US federal courts. Other potash producers were also defendants in these cases. Each of the separate complaints alleges conspiracy to fix potash prices, to divide markets, to restrict supply and to fraudulently conceal the conspiracy, all in violation of Section 1 of the Sherman Act and/or certain states’ laws. In January 2013, the company and PCS Sales (USA), Inc. settled the eight private antitrust lawsuits for a total of $44. The settlements are subject to final approval of the US District Court for the Northern District of Illinois. The court issued an order granting final approval of the settlements with the plaintiffs on June 12, 2013. The company and PCS Sales (USA), Inc. expressly deny any wrongdoing but decided to settle after weighing the multi-year financial cost and resources that would be required to defend these meritless allegations. The other potash producers who were defendants in these cases also have settled with the plaintiffs.

In addition, various other claims and lawsuits are pending against the company in the ordinary course of business. While it is not possible to determine the ultimate outcome of such actions at this time, and inherent uncertainties exist in predicting such outcomes, it is the company’s belief that the ultimate resolution of such actions is not reasonably likely to have a material adverse effect on its consolidated financial position or results of operations.

The breadth of the company’s operations and the global complexity of tax regulations require assessments of uncertainties and judgments in estimating the taxes it will ultimately pay. The final taxes paid are dependent upon many factors, including negotiations with taxing authorities in various jurisdictions, outcomes of tax litigation and resolution of disputes arising from federal, provincial, state and local tax audits. The resolution of these uncertainties and the associated final taxes may result in adjustments to the company’s tax assets and tax liabilities.

The company owns facilities that have been either permanently or indefinitely shut down. It expects to incur nominal annual expenditures for site security and other maintenance costs at certain of these facilities. Should the facilities be dismantled, certain other shutdown-related costs may be incurred. Such costs are not expected to have a material adverse effect on the company’s consolidated financial position or results of operations and would be recognized and recorded in the period in which they are incurred.

13. Guarantees

The environmental regulations of the Province of Saskatchewan require each potash mine to have decommissioning and reclamation plans, and financial assurances for these plans, approved by the responsible provincial minister. The Minister of the Environment for Saskatchewan (“MOE”) has approved the plans previously submitted by the company, which had provided a CDN $2 irrevocable letter of credit and a payment of CDN $3 into the agreed-upon trust fund. Under the regulations, the decommissioning and reclamation plans and financial assurances are to be reviewed at least once every five years, or as required by the MOE. The most recent scheduled review was to be completed by June 30, 2011. The company submitted its decommissioning and reclamation plans and its financial assurances proposal in May 2011. The MOE has previously advised that it considers the company in compliance with the regulations until the review is finalized. In April 2013, the company received a counter proposal from the MOE that includes a proposed increase to the amount of required funding to a trust fund. The company is currently reviewing the MOE counter proposal. The company does not believe that the funding amounts proposed by the MOE with respect to this matter are reasonably likely to have a material impact on its consolidated financial position or results of operations.

14. Related Party Transactions

The company sells potash from its Saskatchewan mines for use outside Canada and the US exclusively to Canpotex, a potash export, sales and marketing company owned in equal shares by the three producers in Saskatchewan. Sales are at prevailing market prices and are settled on normal trade terms. Sales to Canpotex for the three months ended June 30, 2013 were $495 (2012 — $668) and the six months ended June 30, 2013 were $870 (2012 — $960). At June 30, 2013, $193 (December 31, 2012 — $251) was owing from Canpotex.

15. Comparative Figures

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis is the responsibility of management and is as of July 30, 2013. The Board of Directors carries out its responsibility for review of this disclosure principally through its audit committee, comprised exclusively of independent directors. The audit committee reviews and, prior to its publication, approves this disclosure, pursuant to the authority delegated to it by the Board of Directors. The term “PCS” refers to Potash Corporation of Saskatchewan Inc. and the terms “we,” “us,” “our,” “PotashCorp” and “the company” refer to PCS and, as applicable, PCS and its direct and indirect subsidiaries as a group. Additional information relating to PotashCorp, including our Annual Report on Form 10-K for the year ended December 31, 2012 (Form 10-K), can be found on SEDAR at www.sedar.com and on EDGAR at www.sec.gov/edgar.shtml. The company is a foreign private issuer under the rules and regulations of the US Securities and Exchange Commission (the SEC); however, it currently files voluntarily on the SEC’s domestic forms.

PotashCorp and Our Business Environment

PotashCorp is an integrated producer of fertilizer, industrial and animal feed products. We are the world’s largest fertilizer company by capacity, producing the three primary crop nutrients: potash (K), nitrogen (N) and phosphate (P). As the world’s leading potash producer, we are responsible for approximately 20 percent of global potash capacity through our Canadian operations. To enhance our global footprint, we also have investments in other key global potash-related businesses in South America, the Middle East and Asia. We complement our potash assets with focused positions in nitrogen and phosphate.

We sell fertilizer to North American retailers, cooperatives and distributors that provide storage and application services to farmers, the end users. Our offshore customers are government agencies and private importers that buy under contract and on the spot market; while spot market sales are more prevalent in North America, South America and Southeast Asia. Fertilizers are sold primarily for spring and fall application in both Northern and Southern hemispheres.

Transportation is an important part of the final purchase price for fertilizer so producers usually sell to the closest customers. In North America, we sell mainly on a delivered basis via rail, barge, truck and pipeline. Offshore customers purchase product either at the port where it is loaded or delivered with freight included directly to a specified location.

Potash, nitrogen and phosphate are also used as inputs for the production of animal feed and industrial products. Most feed and industrial sales are by contract and are more evenly distributed throughout the year than fertilizer sales.

PotashCorp Strategy

We believe that our ability to deliver superior long-term financial returns is the cornerstone of establishing enduring value for all stakeholders. Strong financial performance rewards our shareholders and, at the same time, allows us to focus on our broader social and environmental responsibilities and contribute to the long-term success of our customers, employees, suppliers and communities.

In each nutrient segment, we develop strategies and set priorities that align with our broad goals. Each nutrient plays an important part in our success, but we believe our unique leverage in potash offers the greatest opportunity for future growth.

Our strategic approach in potash is to build on our world-class position whenever opportunities arise that can enhance our value, and to focus on matching our production to market demand (to reduce downside risk and conserve the long-term value of our resource, while still striving to grow our volumes as capacity rises). Our strategic approach in nitrogen is to enhance gross margin and earnings stability by being a lower delivered-cost supplier to the large US market, emphasizing ammonia sales to industrial customers that value long-term secure supply, and to focus on initiatives that can reduce our environmental impact. Our strategic approach in phosphate is to leverage our high-quality rock and produce the industry’s most diversified mix of products in an attempt to maximize returns and provide earnings stability, with a focus on reducing our environmental footprint to support the long-term viability of our operations.

We seek to be the supplier of choice to the markets we serve. It is critical to our success that our customers recognize our ability to create value for them based on the price they pay for our products.

As we plan for our future, we carefully weigh our choices for use of our cash flow. We will continue to deploy cash in ways that we believe achieve the best return for our investors, such as enhancing dividends, repurchasing shares and growing our potash business as value-adding opportunities arise.

Key Performance Drivers — Performance Compared to Targets

Through our integrated value model, we set, evaluate and refine our goals and priorities to drive improvements that benefit all those impacted by our business. We demonstrate our accountability by tracking and reporting our progress against targets related to each goal. Our long-term goals and 2013 targets are set out on pages 42 to 52 of our 2012 Annual Integrated Report. A summary of our progress against selected goals and representative annual targets is set out below.

Goal	Representative 2013 Annual Target	Performance to June 30, 2013
Create superior long-term shareholder value.	Exceed total shareholder return performance for our sector and the DAXglobal Agribusiness Index.	PotashCorp’s total shareholder return was -5 percent in the first six months of 2013 compared to our sector’s weighted average return (based on market capitalization) of -13 percent and the DAXglobal Agribusiness Index weighted average return (based on market capitalization) of NIL percent.
Be the supplier of choice to the markets we serve.	Reduce domestic potash net rail cycle time through the Chicago corridor by 10 percent in 2014, compared to 2011 levels.	The domestic potash net rail cycle time through the Chicago corridor during the second quarter of 2013 showed improvement to both the first quarter of 2013 and the comparable second quarter of the benchmark 2011 period. Improved rail performance during the second quarter resulted in a 7 percent reduction in the net rail cycle time in comparison to the 2013 first quarter which was impacted by severe and prolonged winter weather in the Canadian prairies. On a year to date basis we are still slightly above the benchmark 2011 net rail cycle time number but anticipate further improvements in rail performance should allow us to achieve our targeted performance on an annual basis in 2014.
Attract and retain talented, motivated and productive employees who are committed to our long-term goals.	Maintain an annual employee turnover rate (excluding retirements) of 5 percent or less.	Employee turnover rate (excluding retirements) on an annualized basis for the first six months of 2013 was 4.4 percent.
Achieve no harm to people.	Become one of the safest resource companies in the world within five years by achieving a recordable injury rate in the lowest quartile of a best-in-class peer group.	A five-year strategic plan was developed in the second quarter of 2013. A benchmark group of best-in-class peer companies will be developed in the third quarter of 2013.
	Reduce total site recordable injury rate to 1.25 (per 200,000 hours worked) or lower.	During the first six months of 2013, total site recordable injury rate was 1.00.
Achieve no damage to the environment.	Reduce total reportable incidents (releases, permit excursions and spills) by 15 percent from 2012 levels.	Annualized total reportable incidents were up 5 percent during the first six months of 2013 compared to 2012 annual levels. Compared to the first six months of 2012, total reportable incidents were down 17 percent.

Earnings in the second quarter and first half of 2013 were higher than the same periods in 2012 due largely to a $341 million non-tax deductible charge related to the impairment of our investment in Sinofert Holdings Limited (Sinofert) in the second quarter of 2012. Gross margin fell quarter over quarter mainly due to lower potash prices. Year over year, gross margin fell largely due to lower phosphate prices and sales volumes.

The pace of global potash shipments remained robust during the quarter as buyers in all key markets were actively securing new supply. In North America, challenging spring planting conditions affected fertilizer activity in some regions, but a late push by farmers to ensure the required nutrients were in place to maximize yields and economic returns kept dealers engaged throughout the quarter. Shipments from North American producers surpassed the second-quarter and six-month totals of 2012, even as dealers managed their supply to minimize inventories at the close of the planting season. In offshore markets — both contract and spot — buyers actively procured new supply or took delivery of committed tonnes, which helped raise shipments from North American producers to record levels for both the second quarter and the first half. Despite a strong demand environment, increased competitive pressures resulted in lower prices in all key markets relative to the same periods last year.

In nitrogen, robust industrial and agricultural demand led to increased shipments from US producers for most products during the quarter. Even with substantial domestic requirements, a delayed spring application season and significant product availability from offshore suppliers put downward pressure on key benchmark prices. This was most notable in urea as US imports rose sharply during the past nine months, whereas prices for ammonia and other nitrogen products fell less dramatically on tighter supply/demand fundamentals.

Global phosphate markets continued to be impacted by the lack of substantive engagement from buyers in India, the world’s largest phosphate importer. Although fertilizer dealers managed their supply requirements cautiously in the absence of clear market direction, demand in North America stayed relatively strong and shipments from US producers to Latin American countries were robust. Despite India’s return to the solid fertilizer market midway through the quarter, prices for all phosphate fertilizer products trended lower.

Other significant factors that affected earnings in the second quarter of 2013 compared to the same period in 2012 were lower income taxes due to decreased ordinary earnings before taxes and lower share of earnings of equity-accounted investees. Year over year, provincial mining and other taxes increased due to the timing of annual potash production tax accruals and a higher forecasted profit per tonne.

Other comprehensive loss for the second quarter and first half of 2013 was mainly the result of a decrease in the fair value of our investments in Israel Chemicals Ltd. (ICL) and Sinofert, partially offset by a net actuarial gain resulting from a remeasurement of our defined benefit plans. Other comprehensive income for the second quarter of 2012 consisted of the reclassification to income of the unrealized loss on our investment in Sinofert, which was impaired as of June 30, 2012, a reduction in the fair value of our investments in ICL and Sinofert and net actuarial losses resulting from a remeasurement of our defined benefit plans. Other comprehensive income for the first half of 2012 was primarily affected by the second quarter 2012 factors above, except that the fair value of our investment in ICL increased.

Balance Sheet

The most significant contributors to the changes in our statements of financial position were as follows⁽¹⁾:

⁽¹⁾  Direction of arrows refers to increase or decrease.

Assets	Liabilities
i   Available-for-sale investments were mainly impacted by the lower fair value of our investments in ICL and Sinofert. h   Property, plant and equipment increased primarily (72 percent) due to our previously announced potash capacity expansions and other potash projects. i   Receivables fell due to a reduction in income tax, potash production tax and trade receivables from Canpotex Limited (Canpotex). h   Cash provided by operations exceeded cash used to purchase property, plant and equipment, repay short-term debt and long-term debt and pay dividends, resulting in higher cash and cash equivalents.	i   Short-term debt and current portion of long-term debt fell due to the repayment of commercial paper and long-term debt. Long-term debt declined as our senior notes due May 15, 2014 were classified as current during the second quarter of 2013. h   Deferred income tax liabilities increased primarily due to tax depreciation exceeding accounting depreciation, the tax impact on the remeasurement of our defined benefit plans (see Note 4 to the financial statements in this Form 10-Q), reduced deferred tax assets on unexercised stock options and a Canadian income tax rate increase. i   Payables and accrued charges were impacted by (1) lower trade payables; (2) higher dividends payable due to announced increases in dividends per share; and (3) fewer other payables due to decreases in accrued capital expenditures across all plant sites and payments made to settle the company’s eight anti-trust lawsuits.
Equity
h  Equity was impacted by net income, other comprehensive loss (both discussed in more detail above) and dividends declared during the first six months of 2013.

As at June 30, 2013, $501 million (December 31, 2012 — $481 million) of our cash and cash equivalents were held in certain foreign subsidiaries. There are no current plans to repatriate these funds in a taxable manner.

Operating Segment Review

We report our results (including gross margin) in three business segments: potash, nitrogen and phosphate as described in Note 6 to the financial statements in this Form 10-Q. Our reporting structure reflects how we manage our business and how we classify our operations for planning and measuring performance. Management includes net sales in segment disclosures in the unaudited interim condensed consolidated financial statements pursuant to IFRS, which require segmentation based upon our internal organization and reporting of revenue and profit measures derived from internal accounting methods. As a component of gross margin, net sales (and the related per-tonne

amounts) are the primary revenue measures we use and review in making decisions about operating matters on a business segment basis. These decisions include assessments about potash, nitrogen and phosphate performance and the resources to be allocated to these segments. We also use net sales (and the related per-tonne amounts) for business planning and monthly forecasting. Net sales are calculated as sales revenues less freight, transportation and distribution expenses. Realized prices refer to net sales prices.

Our discussion of segment operating performance is set out below and includes nutrient product and/or market performance results, where applicable, to give further insight into these results.

The most significant contributors to the change in total gross margin quarter over quarter were as follows⁽¹⁾:

⁽¹⁾  Direction of arrows refers to impact on gross margin.

Net Sales Prices	Sales Volumes	Cost of Goods Sold
i   Increased competitive pressures resulted in lower prices in all key markets.	h   In North America, robust demand at the farm level pushed sales volumes higher. i   Offshore sales volumes were down largely as a result of a decline in our Canpotex entitlement and a larger percentage of first-half shipments from New Brunswick during the first quarter of 2013.	h   Brine management costs fell as our tolling agreement at Esterhazy expired at the end of 2012. h   4 shutdown weeks were taken in 2013 mainly as a result of weather-related pond issues at our Patience Lake facility (11 shutdown weeks were taken in 2012 due to weather-related pond issues at our Patience Lake facility and unplanned maintenance at our Rocanville and Allan facilities). h   More product from our lower-cost mines went to offshore customers resulting in a positive cost of goods sold variance.
The change in market mix produced an unfavorable variance of $24 million related to sales volumes and a favorable variance of $23 million in sales prices due to less lower-priced standard product being sold to the offshore market and more higher-priced granular sales to North America in 2013.

The most significant contributors to the change in total gross margin year over year were as follows⁽¹⁾:

⁽¹⁾  Direction of arrows refers to impact on gross margin.

Net Sales Prices	Sales Volumes	Cost of Goods Sold
i   Our average realized potash price trailed the first six months of 2012, reflecting lower pricing that took hold late in 2012 and early 2013.	h   With limited dealer inventory carried into 2013 and strong agricultural fundamentals, North American sales volumes grew. Buyer destocking occurred in the first half of 2012. h   Canpotex shipped record first-half volumes due to settlements with China and India occurring earlier than the previous year and less inventory being carried into 2013 in major offshore spot markets.	h   Brine management costs fell as our tolling agreement at Esterhazy expired at the end of 2012. h   20 shutdown weeks were taken in 2013 mainly as a result of our strategy to match production with market demand and weather-related pond issues at our Patience Lake facility (40 shutdown weeks were taken in 2012 to match supply to demand; during this downtime, we opted to allocate resources to non-production activities rather than lay off employees, which resulted in higher shutdown costs).

During the second quarter of 2013, we successfully completed a safe Canpotex entitlement run at Cory which will allow us a greater proportion of Canpotex sales to offshore markets and almost offsets the loss from the ending of our long-term tolling agreement at Esterhazy.

Potash production fell quarter over quarter mainly as a result of reduced operating rates. Potash production increased year over year primarily due to the reduction in shutdown weeks as discussed above.

Total site recordable injury rate declined because of the effort by the site teams and an external consultant on targeted safety improvement projects at Allan, Cory and Rocanville as well as on-going safety improvements at other sites.

Waste is comprised of byproducts, including: coarse and fine tailings and salt as brine to injection wells. Waste increased quarter over quarter due to increased mining waste per tonne combined with increased mining at certain sites, which also contributed to an overall increase in waste year over year.

The increase in environmental incidents in potash for the first six months of 2013 is due largely to several failures of refrigerant lines in new HVAC units installed at New Brunswick.

The most significant contributors to the change in total gross margin quarter over quarter were as follows⁽¹⁾:

⁽¹⁾  Direction of arrows refers to impact on gross margin.

	Net Sales Prices		Sales Volumes		Cost of Goods Sold
i	Our average realized prices fell, primarily reflecting a sharp decline in urea prices due to a delayed spring application season and significant product availability from offshore suppliers.	h	Increased production of downstream nitrogen products was primarily the result of the restart of ammonia capacity at Geismar.	i	Average natural gas costs in production, including hedge, increased 7 percent. Natural gas costs in Trinidad production rose 3 percent (contract price indexed, in part, to Tampa ammonia prices) while our US spot costs for natural gas used in production increased 70 percent. Including losses on our hedge position, US gas prices increased 21 percent.
The change in market mix produced a favorable variance of $47 million related to sales volumes and an unfavorable variance of $34 million in sales prices due to more lower-priced products being sold.				h	The cost of goods sold variance was positive for solutions/nitric acid/ammonium nitrate due to the impact of costs associated with Geismar in 2012 that did not repeat in 2013.

The most significant contributors to the change in total gross margin year over year were as follows⁽¹⁾:

⁽¹⁾  Direction of arrows refers to impact on gross margin.

	Net Sales Prices		Sales Volumes		Cost of Goods Sold
h i	Sales prices rose due to strong spot ammonia pricing achieved in the second half of 2012 that carried over into 2013, despite prices declining throughout the first half of 2013. Urea prices fell due to large import volumes positioned ahead of a delayed spring season and a surge in urea exports from China.	h i	Additional ammonia capacity at Geismar and Augusta led to an increase in saleable tonnes of downstream products. Urea volumes were down as gas interruptions in Trinidad led us to divert more production to higher-margin ammonia.	i	Average natural gas costs in production, including hedge, increased 17 percent. Natural gas costs in Trinidad production rose 22 percent while our US spot costs for natural gas used in production increased 44 percent. Including losses on our hedge position, US gas prices increased 12 percent.
The change in market mix produced a favorable variance of $74 million related to sales volumes and an unfavorable variance of $61 million in sales prices due to more lower-priced products being sold.				i	Increased costs in the first quarter of 2013, due to the restart of a plant at Geismar, caused the cost of goods sold variance for solutions/nitric acid/ammonium nitrate to be higher.

Recordable injuries fell slightly quarter over quarter but the total site recordable injury rate rose as a result of more hours worked in 2012, due to the Geismar ammonia restart project. There were eight recordable injuries in the first half of 2013 compared to seven in the same period in 2012, resulting in an increase in the nitrogen total site recordable injury rate.

Additional greenhouse gases were emitted quarter over quarter due to the startup of our Geismar ammonia plant. On an ongoing basis, CO₂ from production is contracted to be sold to a third party.

The most significant contributors to the change in total gross margin quarter over quarter were as follows⁽¹⁾:

⁽¹⁾  Direction of arrows refers to impact on gross margin.

	Net Sales Prices		Cost of Goods Sold
i	Our average realized phosphate prices for the quarter were down as a result of a decline in prices for fertilizer products.	h	Costs were impacted by lower sulfur costs (down 17 percent) and a positive adjustment to our phosphate asset retirement obligation in 2013 (due to an increase in the relevant discount rates) compared to a negative adjustment in 2012 (due to lower relevant discount rates). Also, 2012 included costs associated with our Aurora workforce reduction.
		i	Ammonia (up 11 percent) and rock input costs were higher.

⁽¹⁾  Direction of arrows refers to impact on gross margin.

	Net Sales Prices		Cost of Goods Sold
i	Our average realized phosphate price was down from the same period last year, with fertilizer products experiencing the largest decline.	h	Costs were impacted by lower sulfur costs (down 20 percent), adjustments to our asset retirement obligations (the relevant discount rates increased in 2013 and decreased in 2012) and our Aurora workforce reduction in the second quarter of 2012.

The phosphate recordable injury rate increased largely due to an increase in employee injuries at Aurora.

Employee turnover fell as a work force reduction at our Aurora location occurred in the second quarter of 2012.

Water usage in our phosphate operations decreased primarily due to more water recycling at our White Springs location (less rain water to recycle in 2012).

Provincial mining and other taxes are comprised mainly of the Saskatchewan potash production tax (PPT) and a resource surcharge. The PPT is comprised of a base tax per tonne of product sold and an additional tax based on mine profit, which is reduced by an amount based on potash capital expenditures. The resource surcharge is 3 percent of the value of the company’s Saskatchewan resource sales. The PPT expense in the first six months of 2013 was higher than in the same period in 2012. This increase was due in part to a higher proportion of forecasted annual gross margin earned in the first six months of 2013 as compared to the proportion of forecasted annual gross margin earned in the first six months of 2012. As well, lower forecasted

capital expenditures that were partially offset by lower forecasted potash sales revenue resulted in a higher forecasted profit per tonne, which increased the PPT expense.

Share of earnings of equity-accounted investees pertains primarily to Sociedad Quimica y Minera de Chile S.A. (SQM) and APC.

At June 30, 2012, we concluded there was objective evidence that our available-for-sale investment in Sinofert was impaired due to the significance by which fair value was below cost. As a result, we recognized a non-tax deductible impairment loss of $341 million in net income for the three and six months ended June 30, 2012. No such losses were recognized in 2013.

For the second quarter, income taxes decreased due to lower ordinary earnings before taxes. For the first six months of the year, income taxes increased due to higher discrete tax adjustments which were mostly offset by lower income taxes on reduced ordinary earnings before taxes.

Significant items to note include the following:

• In the first six months of 2013, a tax expense of $16 million ($1 million in the second quarter) was recorded to adjust the 2012 income tax provision.

• In second-quarter 2013, a deferred tax expense of $11 million was recorded as a result of a Canadian income tax rate increase.

• In second-quarter 2012, the impairment of the company’s available-for-sale investment in Sinofert was not deductible for tax purposes.

For the first six months of 2013, 49 percent of the effective tax rate on the current year’s ordinary earnings pertained to current income taxes and 51 percent related to deferred income taxes. For the first six months of 2012, 59 percent of the effective tax rate on the year’s ordinary earnings pertained to current income taxes and 41 percent related to deferred income taxes. The decrease in the current portion was largely due to increased tax depreciation in Canada and the US.

Liquidity and Capital Resources

Cash Requirements

Contractual Obligations and Other Commitments

Our contractual obligations and other commitments detailed on pages 81 and 82 of our 2012 Annual Integrated Report summarize certain of our liquidity and capital resource requirements, excluding obligations that have original maturities of less than one year, planned (but not legally committed) capital expenditures or potential share repurchases.

Capital Expenditures

Based on anticipated exchange rates, during 2013 we expect to incur capital expenditures, including capitalized interest, of approximately $960 million for opportunity capital and approximately $690 million to sustain operations at existing levels and for major repairs and maintenance (including plant turnarounds).

Page 58 of our 2012 Annual Integrated Report outlines key potash construction projects and their expected total cost, as well as the impact of these projects on capacity expansion/debottlenecking and any expected remaining spending on each project still in progress. The most significant of these potash projects⁽¹⁾ on which funds are expected to be spent in 2013, excluding capitalized interest, are outlined in the table below:

CDN Dollars (millions)	2013 Forecast		Total Forecast(2)		Started		Expected Completion(3) (Description)	Forecasted Remaining Spending (after 2013)(2)
Allan, Saskatchewan	$	50	$	770		2008	2012 (general expansion)	$	—
New Brunswick	$	160	$	2,180		2007	2013 (mine shaft and mill)	$	370
Rocanville, Saskatchewan	$	540	$	2,810		2008	2014 (mine shaft and mill)	$	220

⁽¹⁾  The expansion at each of these projects is discussed in the technical report for such project filed on SEDAR in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects.

⁽²⁾  Amounts are based on the most recent forecast amounts approved by the Board of Directors, and are subject to change based on project timelines, cost changes and ongoing project reviews.

⁽³⁾  Excludes ramp-up time. We expect these projects will be fully ramped up by the end of 2015, subject to market conditions.

In 2011, we began the process to restart our anhydrous ammonia plant in Geismar, Louisiana. We invested approximately $260 million ($20 million in 2013) to increase ammonia production by an estimated 500,000 tonnes. We started production in the first quarter of 2013.

We anticipate starting an expansion of ammonia production at our Lima, Ohio plant in 2013. We are investing approximately $190 million through the fourth quarter of 2015 ($40 million in 2013) to increase our capacity in ammonia (88,000 tons) and urea (80,000 tons).

We anticipate that all capital spending will be financed by internally generated cash flows supplemented, if and as necessary, by borrowing from existing financing sources.

Sources and Uses of Cash

Cash flows from operating, investing and financing activities, as reflected in the unaudited interim Condensed Consolidated Statements of Cash Flow, are summarized in the following table:

Liquidity needs can be met through a variety of sources, including: cash generated from operations, drawdowns under our revolving credit facility, issuances of commercial paper and short-term borrowings under our line of credit. Our primary uses of funds are operational expenses, sustaining and opportunity capital spending, intercorporate investments, dividends, interest and principal payments on our debt securities and share repurchases.

Cash provided by operating activities was flat quarter over quarter. The following factors had an offsetting effect:

• Higher quarterly net income in 2013;

• A non-cash impairment charge in second-quarter 2012 (none in second-quarter 2013);

• Increased cash inflows from receivables in the second quarter of 2013 (cash outflows from receivables in the second quarter of 2012); and

• Increased cash outflows from payables and accrued charges in second-quarter 2013.

Cash provided by operating activities rose year over year as a result of:

• Higher net income in the first six months of 2013;

• A non-cash impairment charge in first-half 2012 (none in first-half 2013); and

• Decreased cash outflows associated with payables and accrued charges in first-half 2013.

Cash used in investing activities was primarily for additions to property, plant and equipment, of which approximately 74 percent in the second quarter of 2013 (2012 — 70 percent) and 72 percent in the first half of 2013 (2012 — 71 percent) related to the potash segment.

Cash used in financing activities rose quarter over quarter mainly as a result of increased dividend payments on announced dividend increases. Year over year, the repayment of 10-year senior notes at maturity in 2013 and increased dividend payments resulted in increased cash used in financing activities.

We believe that internally generated cash flow, supplemented by borrowing from existing financing sources, if necessary, will be sufficient to meet our anticipated capital expenditures and other cash requirements for at least the next 12 months, exclusive of any acquisitions or other significant expenditures the company may consider from time to time. At this time, we do not reasonably

expect any presently known trend or uncertainty to affect our ability to access our historical sources of liquidity.

Principal Debt Instruments

⁽¹⁾  The authorized aggregate amount under the company’s commercial paper programs in Canada and the US was $2,500 million. The amounts available under the commercial paper programs are limited to the availability of funds under the credit facility.

⁽²⁾  Letters of credit committed. We also have an uncommitted $32 million letter of credit facility against which $29 million was issued at June 30, 2013.

We use a combination of short-term and long-term debt to finance our operations. We typically pay floating rates of interest on our short-term debt and credit facility, and fixed rates on our senior notes. As at June 30, 2013, we had no outstanding commercial paper.

During the second quarter of 2013, we increased our $2,750 million syndicated credit facility to $3,500 million and extended the maturity to May 31, 2018 (original maturity December 11, 2016) (referred to hereafter as our credit facility), and our $750 million credit facility (maturity May 31, 2013) was terminated.

Our credit facility provides for unsecured advances up to the total facility amount less direct borrowings and amounts committed in respect of commercial paper outstanding. We also have a $75 million short-term line of credit that is available through

PotashCorp 2013 Second Quarter Quarterly Report on Form 10-Q 34

August 2013 and an uncommitted letter of credit facility of $32 million that is due on demand. Direct borrowings, outstanding commercial paper and outstanding letters of credit reduce the amounts available under the line of credit and the credit facility. The line of credit and credit facility have financial tests and other covenants (detailed in Note 9 to the 2012 audited annual consolidated financial statements) with which we must comply at each quarter-end. Non-compliance with any such covenants could result in accelerated payment of amounts borrowed and termination of lenders’ further funding obligations under the credit facility and line of credit. We were in compliance with all covenants as of June 30, 2013, and at this time anticipate being in compliance with such covenants in 2013. The accompanying table summarizes the limits and results of certain covenants:

Debt covenants at June 30
Dollars (millions), except ratio amounts	Limit		2013
Debt-to-capital ratio(1)	£	0.60		0.25
Long-term debt-to-EBITDA ratio(2)	£	3.5		0.7
Debt of subsidiaries	<$	1,000	$	6

The following non-IFRS financial measures are requirements of our debt covenants and should not be considered as a substitute for, nor superior to, measures of financial performance prepared in accordance with IFRS:

⁽¹⁾  Debt-to-capital ratio = debt (short-term debt and current portion of long-term debt + long-term debt) / (debt + shareholders’ equity).

⁽²⁾  Long-term debt-to-EBITDA ratio = long-term debt / EBITDA. EBITDA is calculated according to the definition in Notes 9 and 12 to the 2012 audited annual consolidated financial statements for the trailing 12 months. As compared to net income according to IFRS, EBITDA is limited in that periodic costs of certain capitalized tangible and intangible assets used in generating revenues are excluded. Long-term debt to net income for the trailing 12 months was 1.3.

Our ability to access reasonably priced debt in the capital markets is dependent, in part, on the quality of our credit ratings. We continue to maintain investment grade credit ratings for our long-term debt. A downgrade of the credit rating of our long-term debt by Standard & Poor’s would increase the interest rates applicable to borrowings under our credit facility and our line of credit.

Commercial paper markets are normally a source of same-day cash for the company. Our access to the Canadian and US commercial paper markets primarily depends on maintaining our current short-term credit ratings as well as general conditions in the money markets.

For the first six months of 2013, our weighted average cost of capital was 9.5 percent (2012 — 9.2 percent), of which 90 percent represented the cost of equity (2012 — 89 percent).

Outstanding Share Data

We had 866,920,656 common shares issued and outstanding at June 30, 2013, compared to 864,900,513 at December 31, 2012. At June 30, 2013, 23,357,378 options to purchase common shares were outstanding under the company’s ten stock option plans, as compared to 23,164,444 under nine stock option plans at December 31, 2012.

Off-Balance Sheet Arrangements

In the normal course of operations, PotashCorp engages in a variety of transactions that, under IFRS, are either not recorded on our consolidated statements of financial position or are recorded at amounts that differ from the full contract amounts. Principal off-balance sheet activities include operating leases, agreement to reimburse losses of Canpotex, issuance of guarantee contracts, certain derivative instruments and long-term contracts. We do not reasonably expect any presently known trend or uncertainty to affect our ability to continue using these arrangements. Refer to Note 12 to the financial statements in this Form 10-Q for a contingency related to Canpotex. Refer to pages 84 and 85 of our 2012 Annual Integrated Report for information pertaining to our guarantees and derivative instruments. Note 13 to the financial statements in this Form 10-Q contains an update to a certain guarantee. See “Cash Requirements” above and our 2012 Annual Integrated Report for obligations related to operating leases and certain of our long-term raw materials agreements which contain fixed price and/or volume components.

Net income per share for each quarter has been computed based on the weighted average number of shares issued and outstanding during the respective quarter, including the dilutive number of shares assumed for the diluted earnings per share computation; therefore, as the number of shares varies each period, quarterly amounts may not add to the annual total.

Certain aspects of our business can be impacted by seasonal factors. Fertilizers are sold primarily for spring and fall application in both Northern and Southern hemispheres. However, planting conditions and the timing of customer purchases will vary each year and fertilizer sales can be expected to shift from one quarter to another. Most feed and industrial sales are by contract and are more evenly distributed throughout the year.

In the second quarter of 2012, earnings were impacted by a $341 million non-tax deductible impairment loss on our available-for-sale investment in Sinofert due to the significance by which fair value was below cost.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations are based upon the financial statements in this Form 10-Q, which comply with IFRS.

The accounting policies used in preparing the financial statements in this Form 10-Q are consistent with those used in the preparation of the 2012 audited annual consolidated financial statements, except as described in Note 1 to the financial statements in this Form 10-Q. Certain of these policies involve critical accounting estimates because they require us to make particularly subjective or complex judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts could be reported under different conditions or using different assumptions. There have been no material changes to our critical accounting estimate policies in the first six months of 2013.

We have discussed the development, selection and application of our key accounting policies, and the critical accounting estimates and

assumptions they involve, with the audit committee of the Board of Directors, and the committee reviewed the disclosures described in this section.

Recent Accounting Changes

Refer to Note 1 to the financial statements in this Form 10-Q for information pertaining to accounting changes effective in 2013 and for information on issued accounting pronouncements that will be effective in future periods.

Risk Management

Execution of our corporate strategy requires an effective program to manage the associated risks. The PotashCorp Risk Management Framework (the Framework) is applied to identify and manage such risks. The Framework consists of a comprehensive risk universe, with six corporate risk categories, and corresponding identification of risk events. The major corporate categories of risks are: markets/business, distribution, operational, financial, compliance and organizational. Separately and in combination, these risks potentially threaten our strategies and could affect our ability to deliver long-term shareholder value.

The Framework establishes an entity-wide risk ranking methodology. Risk events are evaluated against the criteria of likelihood or frequency of occurrence and the consequential magnitude or severity of the event. Mitigation activities are identified that will reduce the likelihood and/or severity of the occurrence of a risk event. The residual risk that results from identified mitigation activities is also evaluated using the same criteria. Management identifies the most significant risks to our strategy and reports to the Board of Directors on the mitigation plans.

The company’s Risk Management Process of identification, management and reporting of risk is continuous and dynamic. Changes to corporate risk that result from changing internal and external factors are evaluated on a quarterly basis and significant changes in risks and corresponding mitigation activities are reported quarterly to the audit committee. Detailed discussion of the PotashCorp Risk Management Process can be found on pages 29 and 30 of our 2012 Annual Integrated Report as well as in our Form 10-K. Risk management discussions specific to potash, nitrogen and phosphate operations can be found on pages 31 and 32 of the 2012 Annual Integrated Report.

PotashCorp 2013 Second Quarter Quarterly Report on Form 10-Q 36

The company recognizes damage to reputation as one of its most severe risk consequences, which is mitigated by ongoing and transparent communication with stakeholders, commitment to sustainability, and best practices in corporate governance. Moreover, significant investments and operations in a number of countries subject the company to business risks which could be exaggerated by differences in domestic culture, political and economic conditions, policies, laws and regulations. In addition, the company may be adversely affected by changing anti-trust laws in its jurisdictions of operation worldwide. The company may also be adversely affected by unauthorized access to our confidential information, which could result from a security breach of our information technology systems.

The greatest potential risks to potash reported in the 2012 Annual Integrated Report include market supply imbalances which may result from fluctuations in global demand for product or from new competitor supply in the form of greenfield mines, global potash demand insufficient to consume PotashCorp capacity, inadequacy of the transportation and distribution infrastructure to timely accommodate volume delivery demands, physical risks particular to underground mines (such as unexpected underground rock falls and water inflow from underground water-bearing strata), inability to execute and deliver in respect of capital expansions, and safety related risks.

We mitigate the market imbalance and insufficient demand risks by managing production to meet market demand. The company mitigates transportation and distribution risks both directly and through Canpotex by working with carriers and undertaking sufficient capital investment in transportation infrastructure. Underground mine risk mitigation activities include the use of advanced geophysical surveys, microseismic monitoring, rock mechanics modelling, ground penetrating radar, training and procedures and protective structures. We ensure resources are in place for safe and efficient execution of capital plans to mitigate our capital expansions risk. We mitigate the risk of unsafe actions or conditions by enhancing safety systems at all sites. Similar risks of cyclicality and market imbalance exist in phosphate and nitrogen, largely due to competitive costs, availability of supply and government involvement. The company mitigates these risks by focusing on less cyclical markets, maintaining a diversified sulfur supply portfolio and employing natural gas price risk hedging strategies where appropriate.

Outlook

Market Outlook

Although global crop markets experienced volatility in the first half of 2013, the agronomic and economic incentives that drive fertilizer demand remain attractive for farmers. Strong demand for potash, nitrogen and phosphate materialized as expected in the first six months of the year and we anticipate that agricultural conditions will continue to support healthy fertilizer applications in major growing regions for the balance of the year.

In potash, we believe the demand story that is unfolding is a product of renewed growth in many developed and emerging markets. We expect that 2013 global shipments will be similar to the record set in 2011 (nearly 56 million tonnes) with shipments to each major market relatively in line with previous forecasts.

In North America, we anticipate strong engagement through the balance of the year as dealers work to position potash in expectation of an active fall application season. Prices for our summer-fill program reset to $420 per short ton (Midwest warehouse), or approximately $463 per metric tonne, and we are beginning to see buyers returning to the market to restock depleted inventories. While the late spring planting could result in a condensed fall application window, we anticipate that a push by farmers to address declining potassium levels in their soils will result in second-half shipments exceeding historical totals.

Demand from Latin America, especially Brazil, has been particularly strong through the first six months of 2013. We anticipate this market will continue importing potash at high levels in preparation for its key planting season later this year, although it may slow slightly from last year’s record second-half levels. For the year, we forecast total demand in this market will surpass previous period totals.

Shipments of first-half potash volume commitments to China by major suppliers are now reported to be largely complete — with those from Canpotex completed in early July. Discussions on second-half contracts are continuing and we anticipate a new supply agreement will be reached, although shipments during the third quarter could be minimal.

After a slow start to 2013, buyers in other Asian countries (outside of China and India) increased purchases in the second quarter and are working to ensure potash supply will meet anticipated demand. With supportive agronomic and economic incentives in place, we expect total shipments in this region will outpace 2012 levels.

In India, the potash situation remains complex. While an early and healthy monsoon led to an increase in fertilizer demand in June, India’s current fertilizer subsidy program continues to create a large pricing gap between nitrogen and potash fertilizers, and recent currency weakness has intensified the disparity. We do not expect any significant change to our previous forecast of total shipments to this market of approximately 4 million tonnes, although Canpotex’s third-quarter movements could slow from their strong pace in recent months.

Financial Outlook

In this environment, we have revised our financial outlook. We now forecast 2013 potash segment gross margin in the range of $1.8-$2.1 billion, with shipment estimates unchanged at between 8.5 million and 9.2 million tonnes. Included in our sales volumes assumption is an increase in our second-half Canpotex entitlement as a result of successfully proving 3 million tonnes of capacity at our Cory facility, raising PotashCorp’s allocation percentage to approximately 51.5 percent.

37 PotashCorp 2013 Second Quarter Quarterly Report on Form 10-Q

Even with the expectation of a healthy potash order book for the remainder of the year, we have taken the steps necessary to balance our supply with demand — as we have done consistently throughout our history. We plan to take our normal potash maintenance downtime during the third quarter, as well as six additional weeks at Cory. We also intend to operate Lanigan and Rocanville at reduced rates for the rest of 2013. We expect that per-tonne operating costs will rise — as is typical — for the third quarter as a result of reduced production levels, but anticipate annual costs will remain well below those of the previous year.

In nitrogen, the resumption of ammonia production at Geismar has us on track to surpass 2012 sales volumes, although we anticipate slightly lower ammonia availability during the third quarter due to a scheduled turnaround at our Trinidad facility. While the sharp contraction in nitrogen prices appears to be slowing, the full impact of the recent decline is likely to be reflected in our third-quarter realizations. We believe favorable cost variances will help offset lower prices and anticipate gross margin for 2013 could reach record levels.

Despite recent weakness in global phosphate fertilizer prices, we forecast gross margin will remain relatively stable through the balance of the year, aided by expectations that our sales volumes will surpass those of 2012 and the decline of costs for sulfur,

ammonia and our mined phosphate rock. We anticipate that the stability of our feed and industrial products will counter volatility in fertilizer markets and enhance the profitability of our phosphate business.

In this environment, we now forecast nitrogen and phosphate will contribute combined gross margin of $1.3-$1.5 billion for 2013.

Given reduced profitability across the fertilizer industry, we now expect our offshore investments to contribute dividends and equity earnings between $320 million and $340 million for the year.

Other updates to our annual guidance include a reduction in our forecast for selling and administrative costs to $230-$240 million; finance costs adjusted to $130-$150 million; and annual effective income tax rate shifted to a range of 27-28 percent.

Capital expenditures, excluding capitalized interest and major repairs and maintenance, are still anticipated to approximate $1.5 billion.

Based on these factors and guidance items above, PotashCorp now forecasts full-year 2013 net income at $2.45-$2.70 per share, including third-quarter earnings in the range of $0.45-$0.60 per share.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the potential for loss from adverse changes in the market value of financial instruments. The level of market risk to which we are exposed varies depending on the composition of our derivative instrument portfolio, as well as current and expected market conditions. A discussion of enterprise-wide risk management can be found in our 2012 Annual Integrated Report, pages 29 to 32.

Price, foreign exchange and interest rate risks faced by the company and how we manage those risks are outlined in Notes 11 and 24 to the 2012 audited annual consolidated financial statements and there were no significant changes as at June 30, 2013, except as noted below.

Price Risk

The carrying amount of our investments in ICL and Sinofert was $2,011 million at June 30, 2013 (December 31, 2012 — $2,481 million). There were no substantial changes to the price sensitivities reported in Note 24 to the 2012 audited annual consolidated financial statements.

The company’s net exposure to natural gas derivatives in the form of swaps qualifying for hedge accounting was NIL at June 30, 2013 and December 31, 2012.

Foreign Exchange Risk

As at June 30, 2013, the company had entered into foreign currency forward contracts to sell US dollars and receive Canadian dollars in the notional amount of $300 million (December 31, 2012 — $300 million) at an average exchange rate of 1.0363 (December 31, 2012 — 0.9982) per US dollar with maturities in 2013. There were no substantial changes to the US dollar sensitivities reported in Note 24 to the 2012 audited annual consolidated financial statements.

Interest Rate Risk

As at June 30, 2013, the company had no significant exposure to interest rate risk.

Item 4. Controls and Procedures

As of June 30, 2013, we carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon that evaluation and as of June 30, 2013, the Chief Executive

Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports the company files and submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported as and when required and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

There has been no change in our internal control over financial reporting during the quarter ended June 30, 2013 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
