Important factors that could cause actual results to differ materially from our expectations include, among others: the volatility of natural gas prices in North America; the cyclical nature of our business and the agricultural sector; the global commodity nature of our fertilizer products, the impact of global supply and demand on our selling prices, and the intense global competition from other fertilizer producers; conditions in the U.S. agricultural industry; reliance on third party providers of transportation services and equipment; difficulties in completing the implementation of a new enterprise resource planning system and risks associated with cyber security; weather conditions; our ability to complete our recently announced production capacity expansion projects on schedule as planned and on budget or at all; risks associated with other expansions of our business, including unanticipated adverse consequences and the significant resources that could be required; potential liabilities and expenditures related to environmental and health and safety laws and regulations; our potential inability to obtain or maintain required permits and governmental approvals or to meet financial assurance requirements from governmental authorities; future regulatory restrictions and requirements related to greenhouse gas emissions; the seasonality of the fertilizer business; the impact of changing market conditions on our forward sales programs; risks involving derivatives and the effectiveness of our risk measurement and hedging activities; the significant risks and hazards involved in producing and handling our products against which we may not be fully insured; our reliance on a limited number of key facilities; risks associated with joint ventures; acts of terrorism and regulations to combat terrorism; difficulties in securing the supply and delivery of raw materials, increases in their costs and delay or interruptions in their delivery; risks associated with international operations; losses on our investments in securities; deterioration of global market and economic conditions; our ability to manage our indebtedness; and loss of key members of management and professional staff.

EBITDA and Selected Items 11 (in millions) Three months ended March 31, 2013 2012 Net earnings attributable to common stockholders $ 406.5 $ 368.4 Interest expense (income) – net 37.0 30.5 Income taxes 107.4 207.0 Depreciation, depletion and amortization 107.1 103.1 Less: Other adjustments(1) (6.6) (7.5) EBITDA(1) $ 651.4 $ 701.5 Memo: Selected items included above Unrealized mark-to-market (gains) losses on natural gas derivatives $ (22.5) $ 55.9 Losses (gains) on foreign currency derivatives 11.8 - Provision for liability to pre-IPO owners for NOL settlement 55.2 - Total $ 44.5 $ 55.9 (1) EBITDA is defined as net earnings attributable to common stockholders plus interest expense (income)-net, income taxes, and depreciation, depletion and amortization. Other adjustments include the elimination of loan fee amortization that is included in both interest and amortization, and the portion of depreciation that is included in non-controlling interest. We have presented EBITDA because management uses the measure to track performance and believes that it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry.

CFL Selling Price Modifications 12 As of March 31, 2013, CF Industries, Inc. (CF Industries or the Company) owned 49% of the voting common shares and 66% of the non-voting preferred shares of Canadian Fertilizers Limited (CFL), an Alberta, Canada based nitrogen fertilizer manufacturer and purchased 66% of the production of CFL. Viterra, Inc. (Viterra) held 34% of the equity ownership of CFL, purchased the remaining 34% of CFL’s production and was entitled to receive a distribution from CFL equal to 34% of the net earnings. As of March 31, 2013, CFL was a variable interest entity that was consolidated in the Company’s financial statements. CF Industries’ and Viterra’s purchases of nitrogen fertilizer products from CFL were made under product purchase agreements. Under the provisions of these product purchase agreements that were in effect until the fourth quarter of 2012, CFL’s selling prices were based on market prices. An initial portion of the selling price was paid based upon production cost plus an agreed-upon margin once title passed as the product was shipped. The remaining portion of the selling price, representing the difference between the market price and production cost plus an agreed-upon margin, was paid after the end of the year. The sales revenue attributable to this remaining portion of the selling price was accrued on an interim basis. In the Company’s consolidated financial statements, the net sales and accounts receivable attributable to CFL are solely generated by transactions with Viterra, as all transactions with CF Industries are eliminated in consolidation. In the fourth quarter of 2012, the CFL Board of Directors approved an amendment to the product purchase agreements that modified the selling prices that CFL charges for products sold to Viterra and CF Industries. The modified selling price is based on production cost plus an agreed-upon margin and is reflected in the Company’s first quarter 2013 results, whereas, an interim market price accrual of $39.7 million was included in the Company’s first quarter 2012 results. The amendment creates a year-over-year comparability difference for net sales, gross margin, operating earnings, earnings before income taxes and net earnings attributable to noncontrolling interest, but does not impact the comparability of the Company’s net earnings attributable to common stockholders or net cash flows. In order to provide comparable information for the periods presented, the Company has provided certain financial information adjusted as if the modified CFL pricing calculation methodology had been in effect beginning in the first quarter of 2012. The table provided on slide 13 reflects and adjusts for the impact of the change on the Company’s consolidated net sales, gross margin, gross margin as a percent of sales and net earnings attributable to noncontrolling interest. In addition, the table on slide 14 reflects and adjusts for the impact of the change in the CFL pricing calculation methodology on nitrogen segment net sales, gross margin, gross margin as a percent of sales and average selling price per ton of ammonia and urea. In April 2013, CF Industries acquired Viterra’s interest in CFL (including its rights under its product purchase agreement with CFL) for a total purchase price of approximately C$0.9 billion. As a result of the completion of this transaction, CF Industries is entitled to purchase 100% of CFL’s nitrogen fertilizer production.
