PART I.

Item 1. Business.

OVERVIEW

The Mosaic Company is the world’s leading producer and marketer of combined concentrated phosphate and potash crop nutrients for the global agriculture industry. Through our broad product offering, we are a single source supplier of phosphate- and potash-based crop nutrients and animal feed ingredients. We serve customers in approximately 40 countries. We mine phosphate rock in Florida and process rock into finished phosphate products at facilities in Florida and Louisiana. We mine potash in Saskatchewan, New Mexico and Michigan. We have other production, blending or distribution operations in Brazil, China, India, Argentina, and Chile, and a strategic equity investment in a new phosphate rock mine in the Bayovar region in Peru. Our operations include in the top four nutrient-consuming countries in the world.

The Mosaic Company is a Delaware corporation that was incorporated in March 2004 and serves as the parent company of the business that was formed through the October 2004 combination of IMC Global Inc. and the fertilizer businesses of Cargill, Incorporated. On May 25, 2011, we consummated the first in a series of transactions intended to result in the split-off and orderly distribution of Cargill, Incorporated’s then approximately 64% equity interest in us through a series of public offerings. Further information regarding this transaction is described under “Cargill Transaction” in this report. We are publicly traded on the New York Stock Exchange under the ticker symbol “MOS” and are headquartered in Plymouth, Minnesota.

We conduct our business through wholly and majority-owned subsidiaries as well as businesses in which we own less than a majority or a non-controlling interest. We are organized into two reportable business segments: Phosphates and Potash. The following chart shows the respective contributions to fiscal 2012 sales volumes, net sales and operating earnings for each of these business segments:

Phosphates Segment — We are the largest integrated phosphate producer in the world and one of the largest producers of phosphate-based animal feed ingredients in the United States. We sell phosphate-based crop nutrients and animal feed ingredients throughout North America and internationally. Our Phosphates segment also includes our North American and international distribution activities. Our distribution activities include sales offices, port terminals and warehouses in the United States, Canada, and several other key international countries. In addition, the international distribution activities include blending, bagging and production facilities in Brazil, China, India, Argentina and Chile. We accounted for approximately 13% of estimated global production and 58% of estimated North American production of concentrated phosphate crop nutrients during fiscal 2012.

Table of Contents

Potash Segment — We are the fourth-largest producer of potash in the world. We sell potash throughout North America and internationally, principally as fertilizer, but also for use in industrial applications and, to a lesser degree, as animal feed ingredients. We accounted for approximately 12% of estimated global potash production and 39% of estimated North American potash production during fiscal 2012.

Cargill Transaction

Following Cargill’s fiscal 2011 split-off (the “Split-off”) and debt exchange (the “Debt Exchange”) in which it divested its approximately 64% equity interest in us, in fiscal 2012 we completed several additional transactions in furtherance of the planned orderly distribution of our stock that Cargill stockholders (the “Exchanging Cargill Stockholders”) acquired from it in the Split-off.

All other shares (approximately 128.8 million shares in the aggregate) of our stock received by the Exchanging Cargill Stockholders in the Split-off and not sold in the underwritten public secondary offering that occurred on May 25, 2011 immediately following the Split-off are generally subject to transfer restrictions and are to be released in three equal annual installments beginning on November 26, 2013, unless they are sold prior to the release date. We would, at the request of the MAC Trusts or at our own election, register certain of our shares for sale in a secondary offering that could occur each year beginning May 26, 2013. The maximum number of shares that may be included in each such offering is to be determined by the lead underwriter chosen by us for such offering.

Following May 23, 2016, the MAC Trusts will have two rights to request that we file a registration statement under the Securities Act of 1933, pursuant to which the MAC Trusts could sell any remaining shares they received in the Split-off.

Our agreements with Cargill and the Exchanging Cargill Stockholders also contain additional provisions relating to private and market sales under specified conditions.

We have included additional information about the Cargill Transaction in Note 2 of our Consolidated Financial Statements and in response to Item 13 of Part II of this report, which information is incorporated herein by reference, and the principal transaction documents related to the Cargill Transaction are incorporated by reference as exhibits to this report.

Other Business Developments during Fiscal 2012

We continued to execute on our strategic and other priorities. At the core of our strategy is a plan to extend our resource base and invest in the growth of both phosphates and potash. In fiscal 2012, we took the following steps:

We have included additional information about these and other developments in our business during fiscal 2012 in our Management’s Discussion and Analysis of Financial Condition and Results of Operations (“Management’s Analysis”) and in the Notes to our Consolidated Financial Statements.

BUSINESS SEGMENT INFORMATION

The discussion below of our business segment operations should be read in conjunction with the following information that we have included in this report:

Table of Contents

Phosphates Segment

Our Phosphates business segment owns and operates mines and production facilities in Florida which produce concentrated phosphate crop nutrients and phosphate-based animal feed ingredients, and processing plants in Louisiana which produce concentrated phosphate crop nutrients. Our Phosphates segment’s results include our North American distribution activities and the consolidated results of Phosphate Chemicals Export Association, Inc. (“PhosChem”), a U.S. Webb-Pomerene Act association of phosphate producers which exports concentrated phosphate crop nutrient products around the world for us and PhosChem’s other member.

U.S. Phosphate Crop Nutrients and Animal Feed Ingredients

We are the largest producer of concentrated phosphate crop nutrients and animal feed ingredients in the world. Our U.S. phosphates operations have capacity to produce approximately 4.3 million tonnes of phosphoric acid (“P₂O₅ ”) per year, or about 9% of world capacity and about 45% of North American capacity. Phosphoric acid is produced by reacting finely ground phosphate rock with sulfuric acid. Phosphoric acid is the key building block for the production of high analysis or concentrated phosphate crop nutrients and animal feed products, and is the most comprehensive measure of phosphate capacity and production and a commonly used benchmark in our industry. Our U.S. phosphoric acid production totaled approximately 3.9 million tonnes during fiscal 2012 and accounted for approximately 10% of estimated global production and 45% of estimated North American output during fiscal 2012.

Our phosphate crop nutrient products are marketed worldwide to crop nutrient manufacturers, distributors and retailers. Our principal phosphate crop nutrient products are:

In addition, our Phosphates segment is one of the largest producers and marketers of phosphate-based animal feed ingredients in the United States. Production of our animal feed ingredients products is located at our New Wales, Florida facility. We market our feed phosphate primarily under the leading brand names of Biofos^® and Nexfos^TM.

Table of Contents

Our primary phosphate crop nutrient production facilities are located in central Florida and Louisiana. The following map shows the locations of each of our phosphate concentrates plants in the United States and the locations of each of our active and planned phosphate mines in Florida:

Annual capacity by plant as of May 31, 2012 and production volumes by plant for fiscal 2012 are listed below:

6

Table of Contents

The phosphoric acid produced at Uncle Sam is shipped to Faustina, where it is used to produce DAP and MAP. Our Faustina plant also manufactures ammonia that is mostly consumed in our concentrate plants.

We produced approximately 7.7 million tonnes of concentrated phosphate crop nutrients for fiscal 2012 and accounted for roughly 13% of estimated world output and 58% of estimated North American production.

Phosphate Rock

Phosphate rock is the key mineral used to produce phosphate crop nutrients and feed phosphate. Our phosphate rock production totaled approximately 12.1 million tonnes in fiscal 2012 and accounted for approximately 6% of estimated world production and 43% of estimated North American production. We are the world’s second largest miner of phosphate rock and currently operate four mines with a combined annual capacity of approximately 16.0 million tonnes. Production of one tonne of DAP requires between 1.6 and 1.7 tonnes of phosphate rock.

All of our wholly owned phosphate mines and related mining operations are located in central Florida. During fiscal 2012, we operated four active mines: Four Corners, South Fort Meade, Hookers Prairie and Wingate. We plan to develop two large mines at Ona and at DeSoto to replace mines that will be depleted at various times during the next decade.

The phosphate deposits of Florida are of sedimentary origin and are part of a phosphate-bearing province that extends from southern Florida north along the Atlantic coast into southern Virginia. Our active phosphate mines are primarily located in what is known as the Bone Valley Member of the Peace River Formation in the Central Florida Phosphate District. The southern portions of the Four Corners and Wingate mines are in what is referred to as the Undifferentiated Peace River Formation, in which our future Ona and DeSoto mines would also be located. Phosphate mining has been conducted in the Central Florida Phosphate District since the late 1800’s. The potentially mineable portion of the district encompasses an area approximately 80 miles in length in a north-south direction and approximately 40 miles in width.

We extract phosphate ore using large surface mining machines that we own called “draglines.” Prior to extracting the ore, the draglines must first remove a 10 to 50 foot layer of sandy overburden. At our Wingate mine, we also utilize dredges to remove the overburden and mine the ore. We then process the ore at beneficiation plants that we own at each active mine where the ore goes through washing, screening, sizing and flotation processes designed to separate the phosphate rock from sands, clays and other foreign materials. Prior to commencing operations at any of our planned future mines, we would need to acquire new draglines or move existing draglines to the mines and, unless the beneficiation plant at an existing mine were used, construct a beneficiation plant.

Table of Contents

The following table shows, for each of our phosphate mines, annual capacity as of May 31, 2012 and rock production volume and grade for the past three fiscal years:

We also purchase phosphate rock. The level of our purchases of phosphate rock in the future will depend upon, among other factors, our phosphate rock mining plans, the status of our permits, our need for additional phosphate rock to allow us to operate our concentrates plants at or near full capacity, the quality and level of impurities in the phosphate rock that we mine, and our development or acquisition of additional phosphate rock deposits and mines. Depending on product mix and tonnage requirements, our need for purchased phosphate rock could increase in the future in order to meet product specifications, particularly as we develop our proposed Ona and DeSoto mines.

We have a 35% economic interest in a joint venture, which owns a phosphate rock mine (the “Miski Mayo Mine”) in the Bayovar region of Peru. Our investment in the Miski Mayo Mine and related commercial offtake supply agreement to purchase a share of the phosphate rock from the Miski Mayo Mine reduces our purchases of phosphate rock from other suppliers. The Miski Mayo Mine’s annual production capacity is expected to be 3.9 million tonnes when fully operational.

Reserves

We estimate our phosphate rock reserves based upon exploration core drilling as well as technical and economic analyses to determine that reserves can be economically mined. Proven (measured) reserves are those resources

8

Table of Contents

of sufficient concentration to meet minimum physical, chemical and economic criteria related to our current product standards and mining and production practices. Our estimates of probable (indicated) reserves are based on information similar to that used for proven reserves, but sites for drilling are farther apart or are otherwise less adequately spaced than for proven reserves, although the degree of assurance is high enough to assume continuity between such sites. Proven reserves are determined using a minimum drill hole spacing of two sites per 40 acre block. Probable reserves have less than two drill holes per 40 acre block, but geological data provides a high degree of assurance that continuity exists between sites.

The following table sets forth our proven and probable phosphate reserves as of May 31, 2012:

9

Table of Contents

We generally own the reserves shown for active mines in the table above, with the only significant exceptions being further described below:

In light of the long-term nature of our rights to our reserves, we expect to be able to mine all reported reserves that are not currently owned prior to termination or expiration of our rights. Additional information regarding permitting is included in Part I, Item 1A, “Risk Factors”, under “Environmental, Health and Safety Matters—Operating Requirements and Permitting” in our Management’s Analysis, and under “Phosphate Mine Permitting in Florida” in Note 22 of our Consolidated Financial Statements.

Sulfur

We use molten sulfur at our phosphates concentrates plants to produce sulfuric acid primarily for use in our production of phosphoric acid. We purchased approximately 3.6 million long tons of sulfur during fiscal 2012. We purchase most of this sulfur from North American oil and natural gas refiners who are required to remove or recover sulfur during the refining process. Production of one tonne of DAP requires approximately 0.40 long tons of sulfur. We procure our sulfur from multiple sources and receive it by truck, rail, barge and vessel, either direct to our phosphate plants or have it sent for gathering to terminals that are located on the US gulf coast.

We own and operate sulfur terminals in Houston, Texas and Riverview, Florida. We also lease terminal space in Tampa, Florida; Houston and Beaumont, Texas. We own two ocean-going barges and contract for operation of another ocean-going vessel that transport molten sulfur from the Texas terminals to Tampa and then onward by

10

Table of Contents

truck to our Florida phosphate plants. In addition, we own a 50% equity interest in Gulf Sulphur Services Ltd., LLLP (“Gulf Sulphur Services”), which is operated by our joint venture partner. Gulf Sulphur Services has a large sulfur transportation and terminaling business in the Gulf of Mexico, and handles these functions for a substantial portion of our Florida sulfur volume. Gulf Sulphur Services’ capabilities include melting solid sulfur into the molten form that we use, which permits us to access sources of solid as well as molten sulfur. We further round out our sulfur logistic assets with a large fleet of leased railcars that supplement our marine sulfur logistic system. Our Louisiana operations are served by truck, rail and barge from nearby refineries.

Although sulfur is readily available from many different suppliers and can be transported to our phosphate facilities by a variety of means, sulfur is an important raw material used in our business that has in the past been and may in the future be the subject of volatile pricing and availability. Alternative transportation and terminaling facilities might not have sufficient capacity to fully serve all of our facilities in the event of a disruption to current transportation or terminaling facilities. Changes in the price of sulfur or disruptions to sulfur transportation or terminaling facilities could have a material impact on our business. We have included a discussion of sulfur prices in our Management’s Analysis.

Ammonia

We use ammonia together with phosphoric acid to produce both DAP, MAP and MES. We used approximately 1.4 million tonnes of ammonia during fiscal 2012. Production of one tonne of DAP requires approximately 0.23 tonnes of ammonia.

Our Florida ammonia needs are supplied by offshore producers, under multi-year and annual contracts. Ammonia for our New Wales and Riverview plants is terminaled through an ammonia facility at Port Sutton, Florida that we lease for a term expiring in 2013, which we may extend for up to five additional years. A third party operates the Port Sutton ammonia facility pursuant to an agreement that expires in 2013, which we may extend for an unlimited number of additional five year terms, as long as we or the other party is entitled to operate the ammonia facility. Ammonia for our Bartow plant is terminaled through another ammonia facility owned and operated by a third party at Port Sutton, Florida pursuant to an agreement that expires in calendar 2012. Ammonia is transported by pipeline from the terminals to our production facilities. The service agreement with the pipeline providers for Bartow will expire at the end of calendar year 2012. The service agreements with the pipeline provider for New Wales and Riverview were due for renewal on June 30, 2012. We plan to execute an interim agreement to ensure continuity of service until the final terms can be agreed upon and accepted by both parties.

We produce ammonia at Faustina, Louisiana primarily for our own consumption. Our annual capacity is approximately 500,000 tonnes. From time to time we may sell surplus ammonia to unrelated parties.

Although ammonia is readily available from many different suppliers and can be transported to our phosphates facilities by a variety of means, ammonia is an important raw material used in our business that has in the past been and may in the future be the subject of volatile pricing, and alternative transportation and terminaling facilities might not have sufficient capacity to fully serve all of our facilities in the event of a disruption to existing transportation or terminaling facilities. Changes in the price of ammonia or disruptions to ammonia transportation or terminaling could have a material impact on our business. We have included a discussion of ammonia prices in our Management’s Analysis.

Natural Gas

Natural gas is the primary raw material used to manufacture ammonia. At our Faustina facility, ammonia is manufactured on site. The majority of natural gas is purchased through firm delivery contracts based on published index-based prices and is sourced from Texas and Louisiana via pipelines interconnected to the Henry Hub. We use over-the-counter swap and/or option contracts to forward price portions of future gas purchases.

11

Table of Contents

The portions of gas purchases not forward priced are purchased at the index based prices or at domestic spot market prices under short-term contracts. On average, we purchase approximately 14 million MMbtu of natural gas per year for use in ammonia production at Faustina.

Because our ammonia requirements for our Florida operations are purchased rather than manufactured on site, we purchase on average approximately two million MMbtu of natural gas per year in Florida only as a thermal fuel for various production processes.

Florida Land Holdings

We are a significant landowner in the State of Florida, which in the future is expected to return to its historical status as one of the fastest areas of population growth in the United States. We own land comprising approximately 255,000 acres held in fee simple title in central Florida, and have the right to mine additional properties which contain phosphate rock reserves. Some of our land holdings are needed to operate our Phosphates business, while a portion of our land assets, such as reclaimed properties, are not related to our operations. As a general matter, more of our reclaimed property becomes available for uses other than for phosphate operations each year. Our land assets are generally comprised of concentrates plants, port facilities, phosphate mines and other property which we have acquired through our presence in Florida. We are currently taking initial steps as part of a long-term future land use strategy to optimize the value of our land assets. For example, during fiscal 2011 we began development of Streamsong, a destination resort and conference center, in certain areas of previously mined land as part of our long-term business strategy to maximize the value and utility of our extensive land holdings in Florida. The resort and conference center are expected to be completed in calendar 2013.

International Production

Our international operations include production in Brazil and Argentina. Our production facilities include plants that produce up to 800,000 tonnes per year of single superphosphate (“SSP”) and granulated SSP crop nutrients by mixing sulfuric acid with phosphate rock purchased from unrelated third party and the Miski Mayo Mine.

Potash Segment

We are one of the leading potash producers in the world. We mine and process potash in Canada and the United States and sell potash in North America and internationally. The term “potash” applies generally to the common salts of potassium. Muriate of potash (“MOP”) is the primary source of potassium for the crop nutrient industry. Red MOP has traces of iron oxide. The granular and standard grade Red MOP products are well suited for direct fertilizer application and bulk blending. White MOP has a higher percent K₂O. White MOP, besides being well suited for the agricultural market, is used in many industrial applications.

Our potash products are marketed worldwide to crop nutrient manufacturers, distributors and retailers and are also used in the manufacture of mixed crop nutrients and, to a lesser extent, in animal feed ingredients. We also sell potash to customers for industrial use. In addition, our potash products are used for de-icing and as a water softener regenerant.

We operate three potash mines in Canada, including two shaft mines with a total of three production shafts and one solution mine, as well as two potash mines in the United States, including one shaft mine and one solution mine. We also own related refineries at each of the mines.

We have a long term potash capacity expansion plan in Saskatchewan, Canada in response to expected growth in global potash demand. From the inception of our planned brownfield expansions, we expect to increase our annual proven peaking capacity for finished product by approximately five million tonnes by the end of the decade. At our Esterhazy mine K2 shaft and mill, we have substantially completed our expansion and anticipate

12

Table of Contents

the full capacity of an estimated incremental 0.7 million tonnes to be available in fiscal 2013. We are positioning our expansion projects with flexibility in timing so we are able to bring the additional capacity on line when market demand warrants.

POTASH EXPANSION PROJECTS

13

Table of Contents

As shown in the table above, we have realized the first capacity increases from the expansions at our Esterhazy and Colonsay, Saskatchewan potash mines. In addition, we anticipate that significant capacity increases will begin to be realized from expansion projects at our Belle Plaine, Colonsay and Esterhazy, Saskatchewan potash mines beginning in fiscal 2013. All other expansion projects are progressing as planned. We estimate that our total operational capacity including the planned expansions and the Tolling Agreement operational capacity will approximate 15.0 million tonnes. We estimate that our proven peaking capacity including the planned expansions and the Tolling Agreement peaking capacity will approximate 16.1 million tonnes.

14

Table of Contents

The map below shows the location of each of our potash mines.

Our current potash annualized proven peaking capacity, excluding tonnage produced at Esterhazy under the Tolling Agreement, totals 10.3 million tonnes of product per year and accounted for approximately 13% of world capacity and 37% of North American capacity. Production during fiscal 2012, excluding tonnage produced for PCS under the Tolling Agreement, totaled 7.4 million tonnes and accounted for approximately 12% of estimated world production and 39% of estimated North American production.

Table of Contents

The following table shows, for each of our potash mines, annual capacity as of May 31, 2012 and volume of mined ore, average grade and finished product output for the past three fiscal years:

Canadian Mines

We operate three Canadian potash facilities all located in the southern half of the Province of Saskatchewan, including our solution mine at Belle Plaine, two interconnected mine shafts at our Esterhazy shaft mine and our shaft mine at Colonsay.

16

Table of Contents

Extensive potash deposits are found in the southern half of the Province of Saskatchewan. The potash ore is contained in a predominantly rock salt formation known as the Prairie Evaporites. The Prairie Evaporites deposits are bounded by limestone formations and contain the potash beds. Three potash deposits of economic importance occur in Saskatchewan: the Esterhazy, Belle Plaine and Patience Lake members. The Patience Lake member is mined at Colonsay, and the Esterhazy member at Esterhazy. At Belle Plaine all three members are mined. Each of the major potash members contains several potash beds of different thicknesses and grades. The particular beds mined at Colonsay and Esterhazy have a mining height of 11 and 8 feet, respectively. At Belle Plaine several beds of different thicknesses are mined.

Our potash mines in Canada produce MOP exclusively. Esterhazy and Colonsay utilize shaft mining while Belle Plaine utilizes solution mining technology. Traditional potash shaft mining takes place underground at depths of over 1,000 meters where continuous mining machines cut out the ore face and load it onto conveyor belts. The ore is then crushed, moved to storage bins and hoisted to refineries above ground. In contrast, our solution mining process involves heated brine, which is pumped through a “cluster” to dissolve the potash in the ore beds at a depth of approximately 1,500 meters. A cluster consists of a series of boreholes drilled into the potash ore. A separate distribution center at each cluster controls the brine flow. The solution containing dissolved potash and salt is pumped to a refinery where sodium chloride, a co-product of this process, is separated from the potash through the use of evaporation and crystallization techniques. Concurrently, the solution is pumped into a cooling pond where additional crystallization occurs and the resulting product is recovered via a floating dredge. Refined potash is dewatered, dried and sized. Our Canadian operations produce 15 different MOP products, including industrial grades, many through proprietary processes.

Under the Tolling Agreement, we have mined and refined PCS’ potash reserves at our Esterhazy mine for a nominal fee plus a pro rata share of operating and capital costs for approximately forty years. Under the agreement, we have delivered to PCS up to approximately 1.1 million tonnes of potash per year. The Tolling Agreement provided for a term through December 31, 2011 as well as certain renewal terms at the option of PCS, but only to the extent PCS had not received all of its available reserves under the contract. To the extent we have not fully utilized the capacity to satisfy our obligations under the contract, the productive capacity at our Esterhazy mine otherwise used to satisfy our obligations under the Tolling Agreement has been and continues to be available to us for sales to any of our customers at then-current market prices.

As previously reported, on December 7, 2011, we and PCS settled, among other matters, a dispute regarding the expiration of the Tolling Agreement. Under the settlement, the Tolling Agreement expires at December 31, 2012. We agreed to supply approximately 1.1 million tonnes of potash to PCS on existing terms for calendar 2012. We also granted PCS the right, which it has exercised, to take delivery of approximately 0.1 million of the 1.1 million tonnes through the first quarter of calendar 2013. In addition, effective December 31, 2012, we will receive credit for 1.3 million tonnes of capacity at our Esterhazy mine for purposes of calculating our relative share of annual sales of potash to international customers by Canpotex, capacity which is currently allocated to PCS. Canpotex is an export association of certain Canadian potash producers. Canpotex sales are generally allocated among the producer members based on production capacity.

Our potash mineral rights in the Province of Saskatchewan consist of the following:

17

Table of Contents

We believe that our mineral rights in Saskatchewan are sufficient to support current operations for more than a century. Leases are generally renewable at our option for successive terms, generally 21 years each, except that certain of the acres shown above as “Leased from others” are leased under long-term leases with terms (including renewals at our option) that expire from 2023 to 2142.

We pay Canadian resource taxes consisting of the Potash Production Tax and resource surcharge. The Potash Production Tax is a Saskatchewan provincial tax on potash production and consists of a base payment and a profits tax. We also pay a percentage of the value of resource sales from our Saskatchewan mines. In addition to the Canadian resource taxes, royalties are payable to the mineral owners in respect of potash reserves or production of potash. We have included a further discussion of the Canadian resource taxes and royalties in our Management’s Analysis.

Since December 1985, we have effectively managed an inflow of salt saturated brine into our Esterhazy mine. At various times since then, we have experienced changing amounts and patterns of brine inflows at Esterhazy. To date, the brine inflow, including our remediation efforts to control it, have not had a material impact on our production processes or volumes. The volume of the net brine inflow (the rate of inflow less the amount we are pumping out of the mine) or net outflow (when we are pumping more brine out of the mine than the rate of inflow) fluctuates and is dependent on a number of variables, such as the location of the source of the inflow; the magnitude of the inflow; available pumping, surface and underground brine storage capacities; underground injection well capacities; and the effectiveness of calcium chloride and cementatious grout used to reduce or prevent the inflows, among other factors. As a result of these brine inflows, we incur expenditures, certain of which have been capitalized and others that have been charged to expense, in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

It is possible that the costs of remedial efforts at Esterhazy may further increase in the future and that such an increase could be material, or, in the extreme scenario, that the brine inflows, risk to employees or remediation costs may increase to a level which would cause us to change our mining processes or abandon the mine. See “Key Factors that can Affect Results of Operations and Financial Condition” and “Potash Net Sales and Gross Margin” in our Management’s Analysis and “Accidents occurring in the course of our operating activities could result in significant liabilities, interruptions or shutdowns of facilities or the need for significant safety or other expenditures” in Part I, Item 1A, “Risk Factors” in this report, which are incorporated herein by reference, for a discussion of costs, risks and other information relating to the brine inflows. We have begun construction of a new third shaft at the Esterhazy mine as part of our potash expansion plan which is also designed to mitigate risk from current and future inflows.

Due to the ongoing brine inflow at Esterhazy, underground operations at this facility are currently not insurable for water incursion problems. Like other potash producers’ shaft mines, our Colonsay, Saskatchewan, and Carlsbad, New Mexico, mines are also subject to the risks of inflow of water as a result of their shaft mining operations, but water inflow risks at these mines are included in our insurance coverage subject to deductibles, retentions and limits negotiated with our insurers.

United States Mines

In the United States, we have two potash facilities, including a shaft mine located in Carlsbad, New Mexico and a solution mine located in Hersey, Michigan.

Our potash mineral rights in the United States consist of the following:

The Carlsbad ore reserves are of two types: (1) sylvinite, a mixture of potassium chloride and sodium chloride that is the same as the ore mined in Saskatchewan, and (2) langbeinite, a double sulfate of potassium and magnesium. These two types of potash reserves occur in a predominantly rock salt formation known as the Salado Formation. The McNutt Member of this formation consists of eleven units of economic importance, of which we currently mine two. The McNutt Member’s evaporite deposits are interlayered with anhydrite, polyhalite, potassium salts, clay, and minor amounts of sandstone and siltstone.

Continuous underground mining methods are utilized to extract the ore. Drum type mining machines are used to cut the sylvinite and langbeinite ores from the face. Mined ore is then loaded onto conveyors, transported to storage areas, and then hoisted to the surface for further processing at our refinery.

Two types of potash are produced at the Carlsbad refinery. MOP is the primary source of potassium for the crop nutrient industry. Double sulfate of potash magnesia is the second type of potash, which we market under our brand name K-Mag^®, and contains sulfur, potassium and magnesium, with low levels of chloride.

At the Carlsbad facility, we mine and refine potash from 73,781 acres of mineral rights. We control these reserves pursuant to either (i) leases from the U.S. government that, in general, continue in effect at our option (subject to readjustment by the U.S. government every 20 years) or (ii) leases from the State of New Mexico that continue as long as we continue to produce from them. These reserves contain an estimated total of 249 million tonnes of potash mineralization (calculated after estimated extraction losses) in two mining beds evaluated at thicknesses ranging from 4.5 feet to in excess of 11 feet. At average refinery rates, these ore reserves are estimated to be sufficient to yield 16 million tonnes of concentrates from sylvinite with an average grade of approximately 60% K₂O and 22 million tonnes of langbeinite concentrates with an average grade of approximately 22% K₂O. At projected rates of production, we estimate that Carlsbad’s reserves of sylvinite and langbeinite are sufficient to support operations for approximately 31 years and 22 years, respectively.

At Hersey, Michigan, we operate a solution mining facility which produces salt and potash. Mining occurs in the Michigan Basin in a predominantly rock salt formation called the Salina Group Evaporite. This formation is a clean salt deposit with interlayered beds of sylvinite and carbonate. At the Hersey facility, our mineral rights consist of 581 acres owned in fee and 1,799 acres controlled under leases that, in general, continue in effect at our option as long as we continue our operations at Hersey. These lands contain an estimated 41 million tonnes of potash mineralization contained in two beds ranging in thickness from 14 to 30 feet.

Royalties for the U.S. operations amounted to approximately $18.8 million for fiscal 2012. These royalties are established by the U.S. Department of the Interior, Bureau of Land Management, in the case of the Carlsbad leases from the U.S. government, and pursuant to provisions set forth in the leases, in the case of the Carlsbad state leases and the Hersey leases.

Reserves

Our estimates below of our potash reserves and non-reserve potash mineralization are based on exploration drill hole data, seismic data and actual mining results over more than 35 years. Proven reserves are estimated by identifying material in place that is delineated on at least two sides and material in place within a half-mile radius or distance from an existing sampled mine entry or exploration core hole. Probable reserves are estimated by identifying material in place within a one mile radius from an existing sampled mine entry or exploration core hole. Historical extraction ratios from the many years of mining results are then applied to both types of material to estimate the proven and probable reserves. We believe that all reserves and non-reserve potash mineralization reported below are potentially recoverable using existing production shaft and refinery locations.

Table of Contents

Our estimated recoverable potash reserves and non-reserve potash mineralization as of May 31, 2012 for each of our mines is as follows:

As discussed more fully above, we either own the reserves and mineralization shown above or lease them pursuant to mineral leases that generally remain in effect or are renewable at our option, or are long-term leases. Accordingly, we expect to be able to mine all reported reserves that are leased prior to termination or expiration of the existing leases.

Natural Gas

Natural gas is used at our potash solution mines as a fuel to produce steam and to dry potash products. The steam is used to generate electricity, in evaporation and crystallization processes and to provide thermal heat to the solution mining process. Our two solution mines accounted for approximately 81% of our Potash segment’s total natural gas requirements for potash production in fiscal 2012. At our shaft mines, natural gas is used as a fuel to heat fresh air supplied to the shaft mines and for drying potash products. Combined natural gas usage for both the solution and shaft mines approximated 17 million MMbtu for fiscal 2012. We purchase our natural gas requirements on firm delivery index price-based physical contracts and on short term spot-priced physical contracts. Our Canadian operations purchase all of their physical gas in Saskatchewan via the TransGas pipeline system using AECO price indices as pricing references. The U.S. potash operations in Michigan and New Mexico purchase physical gas in their respective regional markets via the MichCon and El Paso Permian Basin market hubs as pricing references, respectively. We use financial derivative contracts to manage the price of portions of our future purchases.

SALES AND DISTRIBUTION ACTIVITIES

United States and Canada

We have a United States and Canada sales and marketing team that serves our business segments. We sell to wholesale distributors, retail chains, cooperatives, independent retailers and national accounts.

Customer service and the ability to effectively minimize the overall supply chain costs are key competitive factors in the crop nutrient and animal feed ingredients businesses. In addition to our production facilities, to service the needs of our customers, we own, lease or have contractual throughput or other arrangements at strategically located distribution warehouses along or near the Mississippi and Ohio Rivers as well as in other key agricultural regions of the United States and Canada. From these facilities, we market Mosaic produced phosphate and potash products for customers who in turn resell the product into the distribution channel or directly to farmers in the United States and Canada.

We own port facilities in Savage, Minnesota as well as warehouse distribution facilities in Pekin, Illinois; Henderson, Kentucky; Melbourne, Kentucky; and Houston, Texas, which has a deep water berth providing access to the Gulf of Mexico.

In addition to the geographically situated facilities that we own, our U.S. distribution operations also include leased distribution space or contractual throughput agreements in other key geographical areas such as California, Florida, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maryland, Minnesota, Nebraska, New York, North Dakota, Pennsylvania and Texas.

Our Canadian customers include independent dealers and national accounts. We also lease and own warehouse facilities in Saskatchewan, Ontario, Quebec and Manitoba in Canada.

International

Outside of the United States and Canada, we market our Phosphates segment’s products through PhosChem, as well as our Phosphates segment’s own international distribution activities. During fiscal 2012, PhosChem marketed approximately 70% of our phosphate export sales volume. We administer PhosChem on behalf of PhosChem’s member companies. We estimate that PhosChem’s sales represent approximately 59% of total U.S. export volume of concentrated phosphates and 13% of global trade volume. The countries that account for the largest amount of PhosChem’s sales of concentrated phosphates include India, Australia, Brazil, Japan and Colombia. During fiscal 2012, PhosChem’s dry concentrated phosphates exports to Asia were 50% of total dry shipments by volume, with India representing 40% of PhosChem’s total dry concentrated phosphates export shipments.

Our sales outside of the United States and Canada of Saskatchewan potash products are made through Canpotex. Canpotex sales are generally allocated among its members based on production capacity. We currently supply approximately 37.1%, by volume, of Canpotex’s requirements. Our potash exports from Carlsbad are sold through our own sales force. We also market our Potash segment’s products through our Phosphates segment, which acquires its potash primarily through Canpotex. The largest amount of international potash sales are to Brazil, Indonesia, China, India, Malaysia, Korea, Japan, Thailand, Vietnam and Australia.

Our Phosphates segment also purchases phosphates, potash and nitrogen products from unrelated third parties to produce blended crop nutrients (“Blends”).

To service the needs of our customers, our international distribution activities include a network of strategically located sales offices, crop nutrient blending and bagging facilities, port terminals and warehouse distribution facilities that we own and operate in key geographic areas throughout several countries. The blending and

21

Table of Contents

bagging facilities primarily produce Blends from phosphate, potash and nitrogen. The average product mix in our Blends (by volume) contains approximately 50% phosphate, 25% potash and 25% nitrogen, although this mix differs based on seasonal and other factors. Our international operations serve primarily as a sales outlet for our North American Phosphates production, both for resale and as an input for Blends. Our Potash segment also has historically furnished a portion of the raw materials needs for the production of Blends, primarily via Canpotex, and is expected to continue to do so in the future.

The following maps show the locations of our primary distribution operations in South America and Asia:

Other Products

With a strong brand position in a multi-billion dollar animal feed ingredients global market, our Phosphates segment supplies animal feed ingredients for poultry and livestock to customers in North America, Latin America and Asia. Our potash sales to non-agricultural users are primarily to large industrial accounts and the animal feed industry. Additionally, we sell potash for de-icing and as a water softener regenerant, as well as fluorosilicic acid for water fluoridation.

COMPETITION

Because crop nutrients are global commodities available from numerous sources, crop nutrition companies compete primarily on the basis of delivered price. Other competitive factors include product quality, cost and availability of raw materials, customer service, plant efficiency and availability of product. As a result, markets for our products are highly competitive. We compete with a broad range of domestic and international producers, including farmer cooperatives, subsidiaries of larger companies, and independent crop nutrient companies. Foreign competitors often have access to cheaper raw materials, are required to comply with less stringent regulatory requirements or are owned or subsidized by governments and, as a result, may have cost advantages over North American companies. We believe that our extensive North American and international production and distribution system provides us with a competitive advantage by allowing us to achieve economies of scale, transportation and storage efficiencies, and obtain market intelligence.

22

Table of Contents

Unlike many of our competitors, we have our own distribution system to sell phosphate- and potash-based crop nutrients and animal feed ingredients, whether produced by us or by other third parties, around the globe. In North America, we have one of the largest and most strategically located distribution systems for crop nutrients, including warehouse facilities in key agricultural regions. We also have an extensive network of distribution facilities internationally, including in the key growth markets of Latin America and Asia, with port terminals, warehouses, and blending plants in the following countries: Brazil, Argentina, Chile, China, and India. Our global presence allows us to efficiently serve customers in approximately 40 countries.

Phosphates Segment

Our Phosphates segment operates in a highly competitive global market. Among the competitors in the global phosphate industry are domestic and foreign companies, as well as foreign government-supported producers in Asia and North Africa. Phosphate producers compete primarily based on price and, to a lesser extent, product quality, service and innovation, such as our MicroEssentials^® product. Major integrated producers of feed phosphates are located in the United States, Europe and China. Many smaller producers are located in emerging markets around the world. Many of these smaller producers are not miners of phosphate rock or manufacturers of phosphoric acid and are required to purchase this material on the open market.

We believe that we are a low cost integrated producer of phosphate-based crop nutrients, due in part to our scale, vertical integration and strategic network of production and distribution facilities. As the world’s largest producer of concentrated phosphates, as well as the second largest miner of phosphate rock in the world and the largest in the United States, we maintain an advantage over some competitors as the scale of operations effectively reduces production costs per unit. We are also vertically integrated to captively supply one of our key inputs, phosphate rock, to our phosphate production facilities. We believe that our position as an integrated producer of phosphate rock provides us with a significant cost advantage over competitors that are non-integrated phosphate producers. Our investment in the Miski Mayo Mine and related commercial offtake supply agreement to purchase a share of the phosphate rock also allows us to reduce our purchases of phosphate rock from other suppliers.

We produce ammonia at our Faustina concentrates plant in quantities sufficient to meet approximately one quarter of our total ammonia needs. With no captive ammonia production in Florida, we are subject to significant volatility in our purchase price of ammonia from world markets. With our own sulfur transportation barges and our 50% ownership interest in Gulf Sulphur Services, we are also well-positioned to source an adequate, flexible and cost-effective supply of sulfur, our third key input. We believe that our investments in sulfur transportation assets continue to afford us a competitive advantage compared to other North American producers in cost and access to sulfur.

With facilities in both central Florida and Louisiana, in addition to dedicated marine and other assets for the transportation and handing of sulfur, we are logistically well positioned to fulfill our needs at very competitive prices. Those multiple production points also afford us the flexibility to optimally balance supply and demand.

We have a strong brand in several of the countries in which we have international distribution activities. In addition to having access to our own production, our international distribution activities have the capability to supply a wide variety of crop nutrients to our dealer/farmer customer base. Our presence in Latin America and Asia allows us to capitalize on the growth in nutrient demand in these large and growing international regions.

We are subject to many environmental laws and regulations in Florida and Louisiana that are often more stringent than those to which producers in other countries are subject.

Potash Segment

Potash is a commodity available from several geographical regions around the world and, consequently, the market is highly competitive. Through our participation in Canpotex, we compete outside of North America with various independent potash producers and consortia as well as other export organizations, including state-owned

23

Table of Contents

organizations. We also ship product from our Carlsbad, New Mexico, potash facility to our South American and Asian distribution centers. Our principal methods of competition with respect to the sale of potash include product pricing, and offering consistent, high-quality products and superior service. We believe that our potash cost structure is competitive in the industry and should improve as we achieve the expected increases in production from our planned expansions.

FACTORS AFFECTING DEMAND

Our results of operations historically have reflected the effects of several external factors which are beyond our control and have in the past produced significant downward and upward swings in operating results. Revenues are highly dependent upon conditions in the agriculture industry and can be affected by, among other factors: crop failure; changes in agricultural production practices; worldwide economic conditions, including the increasing world population, household incomes, and demand for more protein rich food, particularly in developing regions such as China, India, and Latin America; changing demand for biofuels; variability in commodity pricing; governmental policies; the level of inventories in the crop nutrient distribution channels; customer expectations about farmer economics, future crop nutrient prices and availability and transportation costs, among other matters; market trends in raw material costs; market prices for crop nutrients; and weather. Furthermore, our crop nutrients business is seasonal to the extent farmers and agricultural enterprises in the markets in which we compete purchase more crop nutrient products during the spring and fall. The international scope of our business, spanning the northern and southern hemispheres, reduces to some extent the seasonal impact on our business. The degree of seasonality of our business can change significantly from year to year due to conditions in the agricultural industry and other factors. The seasonal nature of our businesses requires significant working capital for inventory in advance of the planting seasons.

We sell products throughout the world. Unfavorable changes in trade protection laws, policies and measures, and other regulatory requirements affecting trade; unexpected changes in tax and trade treaties; strengthening or weakening of foreign economies as well as political relations with the United States may cause sales trends to customers in one or more foreign countries to differ from sales trends in the United States.

Our international operations are subject to risks from changes in foreign currencies, or government policy, which can affect local farmer economics.

OTHER MATTERS

Employees

We had approximately 8,000 employees as of May 31, 2012, consisting of approximately 2,900 salaried and 5,100 hourly employees.

Labor Relations

As of May 31, 2012:

Item 1A. Risk Factors

Our business, financial condition or results of operations could be materially adversely affected by any of the risks and uncertainties described below.

Our operating results are highly dependent upon and fluctuate based upon business and economic conditions and governmental policies affecting the agricultural industry where we or our customers operate. These factors are outside of our control and may significantly affect our profitability.

Our operating results are highly dependent upon business and economic conditions and governmental policies affecting the agricultural industry, which we cannot control. The agricultural products business can be affected by a number of factors. The most important of these factors, for U.S. markets, are:

International market conditions, which are also outside of our control, may also significantly influence our operating results. The international market for crop nutrients is influenced by such factors as the relative value of the U.S. dollar and its impact upon the cost of importing crop nutrients, foreign agricultural policies, the existence of, or changes in, import or foreign currency exchange barriers in certain foreign markets, changes in the hard currency demands of certain countries and other regulatory policies of foreign governments, as well as the laws and policies of the United States affecting foreign trade and investment.

Our most important products are global commodities, and we face intense global competition from other crop nutrient producers that can affect our prices and volumes.

Our most important products are concentrated phosphate crop nutrients, including diammonium phosphate, or DAP, and monoammonium phosphate, or MAP, and muriate of potash, or MOP. We sell most of our DAP, MAP and MOP in the form of global commodities. Our sales of these products face intense global competition from other crop nutrient producers.

27

Table of Contents

Changes in competitors’ production or shifts in their marketing focus have in the past significantly affected both the prices at which we sell our products and the volumes that we sell, and are likely to continue to do so in the future.

Competitors are more likely to increase their production at times when world agricultural and crop nutrient markets are strong, and to focus on sales into regions where their returns are highest. Increases in the global supply of DAP, MAP and MOP or competitors’ increased sales into regions in which we have significant sales could adversely affect our prices and volumes.

Competitors and potential new entrants in the markets for both concentrated phosphate crop nutrients and potash have recently expanded, begun to expand, or announced plans to expand capacity over the next several years. The extent to which current global or local economic and financial conditions, changes in global or local economic and financial conditions, or other factors may cause delays or cancellation of some of these ongoing or planned projects, or result in the acceleration of existing or new projects, is unclear. In addition, the level of exports by producers of concentrated phosphate crop nutrients in China depends to a significant extent on Chinese government actions to curb exports through, among other measures, prohibitive export taxes at times when the government believes it desirable to assure ample domestic supplies of concentrated phosphate crop nutrients to stimulate grain and oilseed production.

In addition, some of our competitors who are expanding their potash production capacity include other members of Canpotex. Canpotex members’ respective shares of Canpotex sales is based upon the members’ respective proven peaking capacity for producing potash. When a Canpotex member expands its production capacity, the new capacity is added to that member’s proven peaking capacity based on a test run at the maximum production level. Antitrust and competition laws prohibit the members of Canpotex from coordinating their production decisions, including the timing of their respective test runs. Worldwide potash production levels during these test runs could exceed then-current market demand, resulting in an oversupply of potash and lower potash prices.

We cannot accurately predict when or whether competitors’ ongoing or planned capacity expansions will be completed, the timing of competitors’ tests to prove peaking capacity for Canpotex purposes, the cumulative effect of these and recently completed expansions, the impact of future decisions by the Chinese government on the level of Chinese exports of concentrated phosphate crop nutrients, or the effects of these or other actions by our competitors on the prices for our products or the volumes that we are able to sell.

Our crop nutrients and other products are subject to price and demand volatility resulting from periodic imbalances of supply and demand, which may cause our results of operations to fluctuate.

Historically, the market for crop nutrients has been cyclical, and prices and demand for our products have fluctuated to a significant extent, particularly for phosphates and, to a lesser extent, potash. Periods of high demand, increasing profits and high capacity utilization tend to lead to new plant investment and increased production. This growth increases supply until the market is over-saturated, leading to declining prices and declining capacity utilization until the cycle repeats.

As a result, crop nutrient prices and volumes have been volatile. This price and volume volatility may cause our results of operations to fluctuate and potentially deteriorate. The price at which we sell our crop nutrient products and our sales volumes could fall in the event of industry oversupply conditions, which could have a material adverse effect on our business, financial condition and results of operations. In contrast, high prices may lead our customers and farmers to delay purchasing decisions in anticipation of future lower prices, thus impacting our sales volumes.

Due to reduced market demand, depressed agricultural economic conditions and other factors, we and our predecessors have at various times suspended or reduced production at some of our facilities. The extent to which we utilize available capacity at our facilities will cause fluctuations in our results of operations, as we will incur

28

Table of Contents

costs for any temporary or indefinite shutdowns of our facilities and lower sales tend to lead to higher fixed costs as a percentage of sales.

Variations in crop nutrient application rates may exacerbate the cyclicality of the crop nutrient markets.

Farmers are able to maximize their economic return by applying optimum amounts of crop nutrients. Farmers’ decisions about the application rate for each crop nutrient, or to forego application of a crop nutrient, particularly phosphate and potash, vary from year to year depending on a number of factors, including among others, crop prices, crop nutrient and other crop input costs or the level of the crop nutrient remaining in the soil following the previous harvest. Farmers are more likely to increase application rates when crop prices are relatively high, crop nutrient and other crop input costs are relatively low and the level of the crop nutrient remaining in the soil is relatively low. Conversely, farmers are likely to reduce or forego application when farm economics are weak or declining or the level of the crop nutrients remaining in the soil is relatively high. This variability in application rates can materially accentuate the cyclicality in prices for our products and our sales volumes.

Our crop nutrient business is seasonal, which may result in carrying significant amounts of inventory and seasonal variations in working capital, and our inability to predict future seasonal crop nutrient demand accurately may result in excess inventory or product shortages.

The crop nutrient business is seasonal. Farmers tend to apply crop nutrients during two short application periods, the strongest one in the Spring before planting and the other in the Fall after harvest. As a result, the strongest demand for our products typically occurs during the Spring planting season, with a second period of strong demand following the Fall harvest. In contrast, we and other crop nutrient producers generally produce our products throughout the year. As a result, we and/or our customers generally build inventories during the low demand periods of the year in order to ensure timely product availability during the peak sales seasons. The seasonality of crop nutrient demand results in our sales volumes and net sales typically being the highest during the North American Spring season and our working capital requirements typically being the highest just prior to the start of the Spring season. Our quarterly financial results can vary significantly from one year to the next due to weather-related shifts in planting schedules and purchasing patterns.

If seasonal demand exceeds our projections, we will not have enough product and our customers may acquire products from our competitors, which would negatively impact our profitability. If seasonal demand is less than we expect, we will be left with excess inventory and higher working capital and liquidity requirements.

The degree of seasonality of our business can change significantly from year to year due to conditions in the agricultural industry and other factors.

The distribution channels for crop nutrients have capacity to build significant levels of inventories. Significant levels of inventories in the distribution channels for crop nutrients can adversely affect our sales volumes and selling prices.

In order to balance the production needs of crop nutrient producers with farmers’ seasonal use of crop nutrients, crop nutrient distribution channels need to have the capacity to build significant inventories. The build-up of inventories in the distribution channels can become excessive, particularly during the cyclical periods of low demand that have been typical in the crop nutrient industry. When there are excessive inventories in the distribution channel, our sales volumes and selling prices can be adversely impacted, even during periods in which farmers’ use of crop nutrients may remain strong.

Changes in transportation costs can affect our sales volumes and selling prices.

The cost of delivery is a significant factor in the total cost to customers and farmers of crop nutrients. As a result, changes in transportation costs or in customer expectations about them can affect our sales volumes and prices.

Table of Contents

Customer expectations about future events can have a significant effect on the demand for our products. These expectations can significantly affect our sales volumes and selling prices.

Customer expectations about future events has had and is expected to continue to have an effect on the demand and prices for crop nutrients. Future events that may be affected by customer expectations include, among others:

Customer expectations about selling prices and availability of crop nutrients has had and is expected to continue to have an effect on the demand for crop nutrients. When customers anticipate increasing crop nutrient selling prices, customers tend to accumulate inventories before the anticipated price increases. This can result in a lag in our realization of rising market prices for our products. Conversely, customers tend to delay their purchases when they anticipate future selling prices for crop nutrients will stabilize or decrease, adversely affecting our sales volumes and selling prices. Customer expectations about availability of crop nutrients can have similar effects on sales volumes and prices.

Similarly, customer expectations about future farmer economics has had and is expected to continue to have an effect on the demand for crop nutrients. When customers anticipate improving farmer economics, customers tend to accumulate crop nutrient inventories in anticipation of increasing sales volumes and selling prices. This can result in a lag in our realization of rising market prices for our products. Conversely, when customers anticipate declining farmer economics, customers tend to reduce the level of their purchases of crop nutrients, adversely affecting our sales volumes and selling prices.

As discussed above, increasing transportation costs effectively increase customers’ and farmers’ costs for crop nutrients and can reduce the amount we realize for our sales. Expectations of decreasing transportation costs can result in customers and farmers anticipating that they may be able to decrease their costs by delaying purchases. As a result, changes in customer expectations about transportation costs can affect our sales volumes and prices.

We conduct our operations primarily through a limited number of key production and distribution facilities. Any disruption at one of these facilities could have a material adverse impact on our business. The risk of material disruption increases when demand for our products results in high operating rates at our facilities.

We conduct our operations through a limited number of key production and distribution facilities. These facilities include our phosphate mines and concentrates plants, our potash mines and the ports and other distribution facilities through which we conduct our business. Any disruption of operations at one of these facilities has the possibility of significantly affecting our production or our ability to distribute our products. Operating these facilities at high rates during periods of high demand for our products increases the risk of mechanical or structural failures, decreases the time available for routine maintenance and increases the impact on our operating results from any disruption. A disruption of operations at one of our key facilities could have a material adverse effect on our results of operations or financial condition.

Insurance market conditions, our loss experience and other factors affect the insurance coverage that we carry, and we are not fully insured against all potential hazards and risks incident to our business. As a result, our insurance coverage may not adequately cover our losses.

We maintain property, business interruption and casualty insurance policies, but we are not fully insured against all potential hazards and risks incident to our business. We are subject to various self-retentions and deductibles

under these insurance policies. As a result of market conditions, our loss experience and other factors, our premiums, self-retentions and deductibles for insurance policies can increase substantially and, in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. In addition, significantly increased costs could lead us to decide to reduce, or possibly eliminate, coverage. As a result, a disruption of operations at one of our key facilities or a significant casualty could have a material adverse effect on our results of operation or financial condition.

Important raw materials and energy used in our businesses in the past have been and may in the future be the subject of volatile pricing. Changes in the price of our raw materials could have a material impact on our businesses.

Natural gas, ammonia and sulfur are key raw materials used in the manufacture of phosphate crop nutrient products. Natural gas is used as both a chemical feedstock and a fuel to produce anhydrous ammonia, which is a raw material used in the production of DAP and MAP. Natural gas is also a significant energy source used in the potash solution mining process. From time to time, our profitability has been and may in the future be impacted by the price and availability of these raw materials and other energy costs. Because most of our products are commodities, there can be no assurance that we will be able to pass through increased costs to our customers. A significant increase in the price of natural gas, ammonia, sulfur or energy costs that is not recovered through an increase in the price of our related crop nutrients products could have a material impact on our business.

During periods when the price for concentrated phosphates is falling because of falling raw material prices, we may experience a lag in realizing the benefits of the falling raw materials prices. This lag can adversely affect our gross margins and profitability.

During some periods, changes in market prices for raw materials can lead to changes in the global market prices for concentrated phosphate crop nutrients. In particular, the global market prices for concentrated phosphate crop nutrients can be affected by changes in the market prices for sulfur, ammonia, phosphate rock and/or phosphoric acid raw materials. Increasing market prices for these raw materials tend to put upward pressure on the selling prices for concentrated phosphate crop nutrients, and decreasing market prices for these raw materials tend to put downward pressure on selling prices for concentrated phosphate crop nutrients. When the market prices for these raw materials plunge rapidly, the selling prices for our concentrated phosphate crop nutrients can fall more rapidly than we are able to consume our raw material inventory that we purchased or committed to purchase in the past at higher prices. As a result, our costs may not fall as rapidly as the selling prices of our products. Until we are able to consume the higher priced raw materials, our gross margins and profitability can be adversely affected.

During periods when the prices for our products are falling because of falling raw material prices, we could be required to write down the value of our inventories. Any such write-down would adversely affect our results of operations and the level of our assets.

We carry our inventories at the lower of cost or market. In periods when the market prices for our products are falling rapidly in response to falling market prices for raw materials, it is possible that we could be required to write down the value of our inventories if market prices fall below our costs. Any such write-down would adversely affect our results of operations and the level of our assets. Any such effect could be material.

Our estimates of future selling prices reflect in part the purchase commitments we have from our customers. As a result, defaults on these existing purchase commitments because of the global or local economic and financial conditions or for other reasons could adversely affect our estimates of future selling prices and require additional inventory write-downs.

In the event of a disruption to existing transportation or terminaling facilities for our products or raw materials, alternative transportation and terminaling facilities might not have sufficient capacity to fully serve all of our customers or facilities.

In the event of a disruption of existing transportation or terminaling facilities for our products or raw materials, alternative transportation and terminaling facilities might not have sufficient capacity to fully serve all of our customers or facilities.

An extended interruption in delivering of products to our customers or the supply of natural gas, ammonia or sulfur to our production facilities could have a material adverse effect on our business, financial condition or results of operations.

We are subject to risks associated with our international sales and operations, which could negatively affect our sales to customers in foreign countries as well as our operations and assets in foreign countries. Some of these factors may also make it less attractive to distribute cash generated by our operations outside the United States to our stockholders, or to utilize cash generated by our operations in one country to fund our operations or repayments of indebtedness in another country or to support other corporate purposes.

For fiscal 2012, we derived approximately 67% of our net sales from customers located outside of the United States. As a result, we are subject to numerous risks and uncertainties relating to international sales and operations, including:

The occurrence of any of the above in the countries in which we operate or elsewhere could jeopardize or limit our ability to transact business there and could adversely affect our revenues and operating results and the value of our assets located outside of the United States.

In addition, tax regulations, currency exchange controls and other restrictions may also make it economically unattractive to:

Our international assets are located in countries with volatile conditions, which could subject us and our assets to significant risks.

We are a global business with substantial assets located outside of the United States and Canada. Our operations in Brazil, Argentina, Chile, China and India are a fundamental part of our business, and we have a joint venture investment in the Miski Mayo mine in Peru that supplies phosphate rock to us. Volatile economic, political and market conditions in these and other emerging market countries may have a negative impact on our operations, operating results and financial condition.

As of the date of this report, there are ongoing protests against several other mining operations in Peru. If these protests were to extend to the Miski Mayo mine, they could adversely affect our investment in the Miski Mayo joint venture or the supply of phosphate rock to us from the mine.

Adverse weather conditions, including the impact of potential hurricanes and excess rainfall, have in the past, and may in the future, adversely affect our operations, particularly our Phosphates business, and result in increased costs, decreased production and potential liabilities.

Adverse weather conditions, including the impact of potential hurricanes and excess rainfall, have in the past and may in the future adversely affect our operations, particularly our Phosphates business. In the past, hurricanes have resulted in minor physical damage to our facilities in Florida and Louisiana. In addition, a release of phosphoric acid process wastewater at our Riverview, Florida facility during a hurricane resulted in a small civil fine, as well as a private class action lawsuit and claims for natural resource damages by governmental agencies.

More significantly, water treatment costs, particularly at our Florida operations, due to high water balances tend to increase significantly following excess rainfall from hurricanes and other adverse weather. Some of our Florida facilities have high water levels that may, from time to time, require treatment. The high water balances at phosphate facilities in Florida also led the Florida Department of Environmental Protection to adopt new rules requiring phosphate production facilities to meet more stringent process water management objectives for phosphogypsum management systems.

If additional excess rainfall or hurricanes continue to occur in coming years, our facilities may be required to take additional measures to manage process water to comply with existing or future requirements and these measures could potentially have a material effect on our business and financial condition.

Adverse weather may also cause a loss of production due to disruptions in our supply chain. For example, oil refineries that supply sulfur to us can be closed as a result of a hurricane and incoming shipments of ammonia can be delayed, disrupting production at our Florida or Louisiana facilities.

Our operations are dependent on having the required permits and approvals from governmental authorities. Denial or delay by a government agency in issuing any of our permits and approvals or imposition of restrictive conditions on us with respect to these permits and approvals may impair our business and operations.

We hold numerous governmental environmental, mining and other permits and approvals authorizing operations at each of our facilities. A decision by a government agency to revoke or substantially modify an existing permit or approval could have a material adverse effect on our ability to continue operations at the affected facility.

Expansion of our operations also is predicated upon securing the necessary environmental or other permits or approvals. Over the next several years, we and our subsidiaries will be continuing our efforts to obtain permits in support of our anticipated Florida mining operations at certain of our properties.

A denial of, or delay in issuing, these permits, the issuance of permits with cost-prohibitive conditions, legal actions that prevent us from relying on permits or revocation of permits, could prevent us from mining at these properties and thereby have a material adverse effect on our business, financial condition or results of operations.

For example:

The periods of shutdown and reduced phosphate rock production at our South Fort Meade mine resulted in costs to suspend operations and idle plant costs. Lower phosphate rock mining production levels also adversely affected gross margin.

We have included additional discussion about permitting for our phosphate mines in Florida under “Environmental, Health and Safety Matters—Permitting” in our Management’s Analysis and in Note 22 of our Consolidated Financial Statements.

We are subject to financial assurance requirements as part of our routine business operations. These financial assurance requirements affect our costs and increase our liquidity requirements. If we were unable to satisfy applicable financial assurance requirements, we might not be able to obtain or maintain permits we need to operate our business as we have in the past. Our need to comply with these requirements could materially affect our business, results of operations or financial condition.

In many cases, as a condition to procuring or maintaining permits and approvals or otherwise, we are required to comply with financial assurance regulatory requirements. The purpose of these requirements is to provide comfort to the government that sufficient funds will be available for the ultimate closure, post-closure care and/or reclamation of our facilities. In most cases, these financial assurance requirements have historically been satisfied without the need for any expenditure of corporate funds to the extent our financial statements meet certain balance sheet and income statement financial strength tests. In the event that we are unable to satisfy these financial strength tests, we must utilize alternative methods of complying with the financial assurance requirements or could be subject to enforcement proceedings brought by relevant government agencies. Potential alternative methods of compliance include negotiating a consent decree that imposes alternative financial assurance or other conditions or, alternatively, providing credit support in the form of cash escrows, surety bonds from insurance companies, letters of credit from banks, or other forms of financial instruments or collateral to satisfy the financial assurance requirements. Use of these alternative means of financial assurance imposes additional expense on us. Some of them, such as letters of credit, also use a portion of our available liquidity. Other alternative means of financial assurance, such as surety bonds, may in some cases require collateral and generally require us to obtain a discharge of the bonds or to post additional collateral (typically in the form of cash or letters of credit) at the request of the issuer of the bonds. Collateral that is required may be in many forms including letters of credit or other financial instruments that utilize a portion of our available liquidity, or in the form of assets such as real estate, which reduces our flexibility to manage or sell assets. In the past, we have also not always been able to satisfy applicable financial strength tests, and in the future, it is possible that we will not be able to pass the applicable financial strength tests, negotiate consent decrees, establish escrow accounts or obtain letters of credit, surety bonds or other financial instruments on acceptable terms and conditions or at a reasonable cost, or that the form and/or cost of compliance could increase, which could materially adversely affect our business, results of operations or financial condition. We have included additional discussion about financial assurance requirements under “Off Balance Sheet Arrangements and Obligations—Other Commercial Commitments” in our Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The other environmental regulations to which we are subject may also have a material adverse effect on our business, financial condition and results of operations.

In addition to permitting and financial assurance requirements, we are subject to numerous other environmental, health and safety laws and regulations in the U.S., Canada, China, Brazil and other countries where we operate. These laws and regulations govern a wide range of matters, including environmental controls, land reclamation, discharges to air and water and remediation of hazardous substance releases. They significantly affect our operating activities as well as the level of our operating costs and capital expenditures. In some international jurisdictions, environmental laws change frequently and it may be difficult for us to determine if we are in compliance with all material environmental laws at any given time.

We are, and may in the future be, involved in legal and regulatory proceedings that could be material to us. These proceedings include “legacy” matters arising from activities of our predecessor companies and from facilities and businesses that we have never owned or operated.

We have in the past been, are currently and may in the future be subject to legal and regulatory proceedings that could be material to our business, results of operations, liquidity or financial condition. These proceedings may be brought by the government or private parties and may arise out of a variety of matters, including:

Table of Contents

The legal and regulatory proceedings to which we are currently or may in the future be subject can, depending on the circumstances, result in monetary damage awards, fines, penalties, other liabilities, injunctions or other court or administrative rulings that interrupt, impede or otherwise materially affect our business operations, and/or criminal sanctions.

Among other environmental laws, the U.S. Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) imposes liability, including for cleanup costs, without regard to fault or to the legality of a party’s conduct, on certain categories of persons, including current and former owners and operators of a site and parties who are considered to have contributed to the release of “hazardous substances” into the environment. Under CERCLA, or various U.S. state analogs, one party may, under certain circumstances, be required to bear more than its proportional share of cleanup costs at a site where it has liability if payments cannot be obtained from other responsible parties. As a crop nutrient company working with chemicals and other hazardous substances, we will periodically incur liabilities and cleanup costs, under CERCLA and other environmental laws, with regard to our current or former facilities, adjacent or nearby third-party facilities or offsite disposal locations.

Pending and potential legal and regulatory proceedings may arise out of our present activities, including operations at current facilities. They may also arise out of past activities by us, our predecessor companies and subsidiaries that our predecessors have sold. These past activities were in some cases at facilities that we and our subsidiaries no longer own or operate and may have never owned or operated.

We have included additional information with respect to pending legal and regulatory proceedings in Note 22 of our Consolidated Financial Statements and in this report in Part I, Item 3, “Legal Proceedings”.

These legal and regulatory proceedings involve inherent uncertainties and could negatively impact our business, results of operations, liquidity or financial condition.

The permitting, financial assurance and other environmental, health and safety laws and regulations to which we are subject may become more stringent over time. This could increase the effects on us of these laws and regulations, and the increased effects could be material.

Continued government and public emphasis on environmental, health and safety issues in the U.S., Canada, China, Brazil and other countries where we operate can be expected to result in requirements that apply to us and our operations that are more stringent than those that are described above and elsewhere in this report. These more stringent requirements may include among other matters increased levels of future investments and

36

Table of Contents

expenditures for environmental controls at ongoing operations which will be charged against income from future operations, increased levels of the financial assurance requirements to which we are subject, increased efforts or costs to obtain permits or denial of permits, other new or interpretations of existing statutes or regulations that impose new or more stringent restrictions or liabilities, including liabilities under CERCLA or similar statutes, including restrictions or liabilities related to elevated levels of naturally-occurring radiation that arise from disturbing the ground in the course of mining activities, and other matters that could increase our expenses, capital requirements or liabilities or adversely affect our business, liquidity or financial condition. In addition, to the extent restrictions imposed in countries where our competitors operate, such as China, India, Former Soviet Union countries or Morocco, are less stringent than in the countries where we operate, our competitors could gain cost or other competitive advantages over us. These effects could be material.

Among other matters, there are several ongoing initiatives relating to nutrient discharges. New regulatory restrictions from these initiatives could have a material effect on either us or our customers. For example:

Regulatory restrictions on greenhouse gas emissions in the United States, Canada or elsewhere could adversely affect us, and these effects could be material.

Various governmental initiatives to limit greenhouse gas emissions are under way or under consideration around the world. These initiatives could restrict our operating activities, require us to make changes in our operating activities that would increase our operating costs, reduce our efficiency or limit our output, require us to make

37

Table of Contents

capital improvements to our facilities, increase our energy, raw material and transportation costs or limit their availability, or otherwise adversely affect our results of operations, liquidity or capital resources, and these effects could be material to us.

Governmental greenhouse gas emission initiatives include among others:

In May 2009, the Province of Saskatchewan, in which our Canadian potash mines are located, began to consider legislation intended to lead to the development and administration of climate change regulation in Saskatchewan by the Province rather than the federal government. Key elements under consideration by the Province include a primary focus on achieving the 20% reduction by 2020 through technological advancements and creation of a Technology Fund to finance low-carbon investments by regulated emitters. As part of this initiative, a Climate Change Foundation will be established to fund research and development projects related to reducing and avoiding greenhouse gas emissions, water conservation, biodiversity conservation, energy efficiency, adaptation planning, and education and public awareness.

Future climate change could adversely affect us.

The prospective impact of potential climate change on our operations and those of our customers and farmers remains uncertain. Some scientists have hypothesized that the impacts of climate change could include changes in rainfall patterns, water shortages, changing sea levels, changing storm patterns and intensities, and changing temperature levels and that these changes could be severe. These impacts could vary by geographic location. At the present time, we cannot predict the prospective impact of potential climate change on our results of operations, liquidity or capital resources, or whether any such effects could be material to us.
