•	Growth: Grow our production of essential crop nutrients and operate with increasing efficiency

•

During 2015, we made equity contributions of $225 million to the Ma'aden Wa'ad Al Shamal Phosphate Company (the “MWSPC”), our joint venture with Saudi Arabian Mining Company (“Ma’aden”) and Saudi Basic Industries Corporation (“SABIC”) to develop, own and operate integrated phosphate production facilities in the Kingdom of Saudi Arabia. We currently estimate that our total cash investment in MWSPC, including the amount we have invested to date, will approximate $850 million. At December 31, 2015, our cash investment was approximately $488 million. We estimate the total cost to develop and construct the integrated phosphate production facilities to be approximately $8 billion. We expect this amount to be funded through external debt facilities, and investments by the joint venture members.

•	We continued the expansion of capacity in our Potash segment, with the K3 shafts at our Esterhazy mine, which are on track to start producing ore in 2017 and are expected to add an estimated 0.9 million tonnes to our potash operational capacity. Once completed, this will provide us the ability to mitigate future brine inflow management costs and risk.

•	Market Access: Expand our reach and impact by continuously strengthening our distribution network

•

We completed the integration of our December 2014 acquisition of Archer Daniels Midland Company's ("ADM") fertilizer distribution business in Brazil and Paraguay (the "ADM Acquisition"). Under the terms of the acquisition agreements, we acquired four blending and warehousing facilities in Brazil, one in Paraguay and additional warehousing and logistics service capabilities. Over time, we expect this acquisition to increase our annual distribution in the region from approximately four million metric tonnes to about six million metric tonnes of crop nutrients.

•	Innovation: Build on our industry-leading product, process and sustainability innovations

•	We continued our efforts to further expand MicroEssentials® capacity, to add an incremental 1.2 million tonnes, and bring total capacity to 3.5 million tonnes by 2017.

•	Total Shareholder return: Deliver strong financial performance and provide meaningful returns to our shareholders

•	In March 2015, our Board of Directors approved an increase in our annual dividend to $1.10 from $1.00 per share, effective with the dividend declaration in May 2015.

•

In May 2015, our Board of Directors authorized a $1.5 billion share repurchase program (the “2015 Repurchase Program”) allowing Mosaic to repurchase shares of our Common Stock, through open market purchases, accelerated share repurchase arrangements, privately negotiated transactions or otherwise. In connection with this authorization, the remaining amount of $149.4 million authorized under the $1.0 billion share repurchase program authorized in 2014 (the “2014 Repurchase Program”) was terminated. The extent to which we repurchase our shares and the timing of any such repurchases depend on a number of factors, including market conditions, the price of our shares, and corporate, regulatory and other considerations.

•	During 2015, an aggregate of 15,558,744 shares of Common Stock was repurchased under our repurchase programs for an aggregate of approximately $698.3 million. As of December 31, 2015, we have approximately $925 million remaining under the 2015 Repurchase Program. We currently have no Class A Shares outstanding.

•	We continued to execute against our cost saving initiatives in ways that are positively impacting financial results. For example, we have reduced our potash cash costs, including realized mark-to-market gains and losses, per production tonne by approximately 10% compared to 2014.

•	We reached agreements with federal and state regulators that, when effective, will resolve claims relating to our management of certain waste materials at fertilizer manufacturing facilities in Florida and Louisiana. After the consent decrees become effective, we will deposit cash in the amount of $630 million into two trust funds as

•	The financial statements and supplementary financial information in our Consolidated Financial Statements (“Consolidated Financial Statements”). This information is incorporated by reference in this report in Part II, Item 8, “Financial Statements and Supplementary Data.”

•

Diammonium Phosphate (18-46-0) Diammonium Phosphate (“DAP”) is the most widely used high-analysis phosphate crop nutrient worldwide. DAP is produced by first combining phosphoric acid with anhydrous ammonia in a reaction vessel. This initial reaction creates a slurry that is then pumped into a granulation plant where it is reacted with additional ammonia to produce DAP. DAP is a solid granular product that is applied directly or blended with other solid plant nutrient products such as urea and potash.

•

Monoammonium Phosphate (11-52-0) Monoammonium Phosphate (“MAP”) is the second most widely used high-analysis phosphate crop nutrient and the fastest growing phosphate product worldwide. MAP is also produced by first combining phosphoric acid with anhydrous ammonia in a reaction vessel. The resulting slurry is then pumped into the granulation plant where it is reacted with additional phosphoric acid to produce MAP. MAP is a solid granular product that is applied directly or blended with other solid plant nutrient products.

•	MicroEssentials® is a value-added ammoniated phosphate product that is enhanced through a patented process that creates very thin platelets of sulfur and other micronutrients, such as zinc, on the granulated product. The patented process incorporates both the sulfate and elemental forms of sulfur, providing season long availability to crops.

---

(a)	Our ability to produce processed phosphates has been less than our annual operational capacity stated in the table above, except to the extent we purchase phosphoric acid.

(b)	Operational capacity is our estimated long-term capacity based on an average amount of scheduled down time, including maintenance and scheduled turnaround time, and product mix, and no significant modifications to operating conditions, equipment or facilities.

(c)	Actual production varies from annual operational capacity shown in the above table due to factors that include among others the level of demand for our products, maintenance and turnaround time, accidents, mechanical failure, product mix, and other operating conditions.

---

(a)	Annual operational capacity is the expected average long-term annual capacity considering constraints represented by the grade, quality and quantity of the reserves being mined as well as equipment performance and other operational factors.

(b)	Actual production varies from annual operational capacity shown in the above table due to factors that include among others the level of demand for our products, the quality of the reserves, the nature of the geologic formations we are

---

(c)	Bone Phosphate of Lime (“BPL”) is a traditional reference to the amount (by weight percentage) of calcium phosphate contained in phosphate rock or a phosphate ore body. A higher BPL corresponds to a higher percentage of calcium phosphate.

(d)	The percent of P2O5 in the above table represents a measure of the phosphate content in phosphate rock or a phosphate ore body. A higher percentage corresponds to a higher percentage of phosphate content in phosphate rock or a phosphate ore body.

(e)	The Hookers Prairie mine’s reserves were exhausted during 2014.

(f)	Production at the South Pasture mine in 2014 reflects rock mined from March of 2014, when the mine was acquired.

(a)	Reserves are in areas that are fully accessible for mining; free of surface or subsurface encumbrance, legal setbacks, wetland preserves and other legal restrictions that preclude permittable access for mining; believed by us to be permittable; and meet specified minimum physical, economic and chemical criteria related to current mining and production practices.

(b)	Reserve estimates are generally established by our personnel without a third party review. There has been no third party review of reserve estimates within the last five years. The reserve estimates have been prepared in accordance with the standards set forth in Industry Guide 7 promulgated by the United States Securities and Exchange Commission (“SEC”).

(c)	Of the reserves shown, 536.2 million tonnes are proven reserves, while probable reserves totaled 32.9 million tonnes.

(d)	Average product BPL ranges from approximately 63% to 65%.

(e)	In connection with the purchase in 1996 of approximately 109.3 million tonnes of the reported DeSoto reserves, we agreed to (i) pay royalties of between $0.50 and $0.90 per ton of rock mined based on future levels of DAP margins, and (ii) pay to the seller lost income from the loss of surface use to the extent we use the property for mining related purposes before January 1, 2020.

•	We own the above-ground assets of the South Fort Meade mine, including the beneficiation plant, rail track and the initial clay settling areas. A limited partnership, South Ft. Meade Partnership, L.P. (“SFMP”), owns the majority of the mineable acres shown in the table for the South Fort Meade mine.

•	We currently have a 95% economic interest in the profits and losses of SFMP. SFMP is included as a consolidated subsidiary in our financial statements.

•

We have a long-term mineral lease with SFMP. This lease expires on the earlier of December 31, 2025 or on the date that we have completed mining and reclamation obligations associated with the leased property. Lease provisions include royalty payments and a commitment to give mining priority to the South Fort Meade phosphate reserves. We pay the partnership a royalty on each BPL short ton mined and shipped from the areas that we lease from it. Royalty payments to SFMP normally average approximately $13 million annually.

•	Through its arrangements with us, SFMP also earns income from mineral lease payments, agricultural lease payments and interest income, and uses those proceeds primarily to pay dividends to its equity owners.

•	The surface rights to approximately 882 acres for the South Fort Meade Mine are owned by SFMP, while the U.S. government owns the mineral rights beneath. We control the rights to mine these reserves under a mining lease agreement and pay royalties on the tonnage extracted. Under the lease, we paid an immaterial amount in royalties to the U.S. Government in 2015.

(a)	Finished product.

(b)	Actual production varies from annual operational capacity shown in the above table due to factors that include among others the level of demand for our products, maintenance and turnaround time, the quality of the reserves and the nature of the geologic formations we are mining at any particular time, accidents, mechanical failure, product mix, and other operating conditions.

(c)	Represents full capacity assuming no turnaround or maintenance time.

(d)

The annualized proven peaking capacity shown above is the capacity currently used to determine our share of Canpotex, Limited ("Canpotex") sales. Canpotex members’ respective shares of Canpotex sales are based upon the members’ respective proven peaking capacities 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 proving run at the maximum production level. The annual operational capacity reported in the table above can exceed the annualized proven peaking capacity until the proving run has been completed. In December 2013, our Esterhazy mine successfully completed a proving run of its expanded capacity, increasing its proven peaking capacity from 5.3 to 6.3 million tonnes, which increased our share of Canpotex sales from approximately 39.9% to 42.5%, effective January 1, 2014. Subsequently, one of Canpotex's other members demonstrated an increase in its capacity, which resulted in lowering our share of Canpotex sales to 38.8%, effective July 1, 2014. Effective January 1, 2015, our share of Canpotex sales increased to 40.6%, as a result of a proving run of our expansion of our Colonsay mine, which was successfully completed in 2014. Effective January 1, 2016, our share of Canpotex sales decreased to 39.1% as one of Canpotex's other members demonstrated an increase in its capacity.

(e)

Annual operational capacity is our estimated long term potash capacity based on the quality of reserves and the nature of the geologic formations expected to be mined, milled and/or processed over the long term, average amount of scheduled down time, including maintenance and scheduled turnaround time, and product mix, and no significant modifications to operating conditions, equipment or facilities. Operational capacities will continue to be updated to the extent new production results impact ore grades assumptions.

(f)	Grade % K2O is a traditional reference to the percentage (by weight) of potassium oxide contained in the ore. A higher percentage corresponds to a higher percentage of potassium oxide in the ore.

(g)	Effective December 28, 2014, we permanently discontinued production of MOP at our Carlsbad facility.

(h)	K-Mag® is a specialty product that we produce at our Carlsbad facility. In 2014, we reduced our annual operational capacity of our K-Mag® due to lower ore grades.

(i)	During the quarter ended September 30, 2013, we decided to sell the salt operations of the Hersey mine and close the related potash operations. The sale of the salt operations was completed on July 29, 2014.

(a)	There has been no third party review of reserve estimates within the last five years. The reserve estimates have been prepared in accordance with the standards set forth in Industry Guide 7 promulgated by the SEC.

(b)	Includes 1.2 billion tonnes of proven reserves and 0.8 billion tonnes of probable reserves.

(c)

The non-reserve potash mineralization reported in the table in some cases extends to the boundaries of the mineral rights we own or lease. Such boundaries are up to 16 miles from the closest existing sampled mine entry or exploration core hole. Based on available geologic data, the non-reserve potash mineralization represents potash that we expect to mine in the future, but it may not meet all of the technical requirements for categorization as proven or probable reserves under Industry Guide 7.

In Florida, local community participation has become an important factor in the permitting process for mining companies, and various local counties and other parties in Florida have in the past and continue to file lawsuits challenging the issuance of some of the permits we require. In fiscal 2009, in connection with our efforts to permit an extension of our Four Corners, Florida, phosphate rock mine, non-governmental organizations for the first time filed a lawsuit in federal court against the U.S. Army Corps of Engineers (the “Corps”) with respect to its actions in issuing a federal wetlands permit. The federal wetlands permit issued by the Corps remained in effect. Mining on the extension commenced and approximately 600 acres were mined and/or disturbed. In September 2013, this lawsuit was dismissed by the United States District Court for the Middle District of Florida, Jacksonville Division.

---

•

Delays in receiving a federal wetlands permit impacted the scheduled progression of mining activities for the extension of our South Fort Meade, Florida, phosphate rock mine into Hardee County. As a result, we began to idle a portion of our mining equipment at the mine in the latter part of fiscal 2010. In June 2010, the Corps issued the federal wetlands permit. Subsequently, certain non-governmental organizations filed another lawsuit in the United States District Court for the Middle District of Florida, Jacksonville Division, contesting the issuance of this federal wetlands permit, alleging that the Corps’ actions in issuing the permit violated several federal laws relating to the protection of the environment. Preliminary injunctions entered into in connection with this lawsuit resulted in shutdowns or reduced production at our South Fort Meade mine until April 2012. Following a settlement of the lawsuit in February 2012 and court approval, we were able to resume normal production at our South Fort Meade mine.

•

Allegations by the government or private parties that we have violated the permitting, financial assurance or other environmental, health and safety laws and regulations discussed above. For example, in connection with the consent decrees referred to above we have agreed, among other things, to pay cash penalties of approximately $8 million in the aggregate, and to modify certain operating practices and undertake certain capital improvement projects over a period of several years that are expected to result in capital expenditures likely to exceed $200 million in the aggregate. We are also involved in other proceedings alleging that, or to review whether, we have violated environmental laws in the United States and Brazil.

•

Other environmental, health and safety matters, including alleged personal injury, wrongful death, complaints that our operations are adversely impacting nearby farms and other business operations, other property damage, subsidence from mining operations, natural resource damages and other damage to the environment, arising out of operations, including accidents. For example, several actions were initiated by the government and private parties related to a release of phosphoric acid process wastewater at our Riverview, Florida facility during a 2004 hurricane.

•

Antitrust, commercial, tax (including tax audits) and other disputes. For example, we were one of a number of defendants in multiple class-action lawsuits, in which the plaintiffs sought unspecified amounts of damages including treble damages, alleging that we and other defendants conspired to, among other matters, fix the price at which potash was sold in the United States, allocated market shares and customers and fraudulently concealed their anticompetitive conduct. In January 2013, we settled these class action antitrust lawsuits for an aggregate of $43.8 million.

The Florida Department of Environmental Protection (“FDEP”) has adopted state nutrient criteria rules (“Florida NNC Rule”) to supplant the requirements of numeric water quality standards for the discharge of nitrogen and/or phosphorus into Florida lakes and streams that were adopted by EPA in December 2010 (the “NNC Rule”). While EPA has withdrawn the federal NNC Rule and the FDEP criteria now are effective, the possibility remains that still-pending litigation relating to the NNC Rule or future litigation could challenge EPA's withdrawal or the effectiveness of the Florida NNC Rule. Subject to further litigation developments, we expect that compliance with the requirements of nutrient criteria rules could adversely affect our Florida Phosphate operations, require significant capital expenditures or substantially increase our annual operating expenses.

The Gulf Coast Ecosystem Restoration Task Force, established by executive order of the President and comprised of five Gulf states and eleven federal agencies, has delivered a final strategy for long-term ecosystem restoration for the Gulf Coast in 2016. The strategy calls for, among other matters, reduction of the flow of excess nutrients into the Gulf through state nutrient reduction frameworks, new nutrient reduction approaches and reduction of agricultural

In March 2012, several nongovernmental organizations brought a lawsuit in federal court against EPA, seeking to require it to establish numeric nutrient criteria for nitrogen and phosphorous in the Mississippi River basin and the Gulf of Mexico. EPA had previously denied a 2008 petition seeking such standards. On May 30, 2012, the court granted our motion to intervene in this lawsuit. On September 20, 2013 the court held that EPA had to respond directly to the environmental organizations’ petition as to whether numeric nutrient criteria for the Mississippi River basin and Gulf of Mexico are “necessary” under the Clean Water Act, but that EPA had the discretion to rely on administrative, policy and other non-technical factors in responding to the petition. EPA appealed the district court decision, and the Fifth Circuit Court of Appeals issued a decision in April 2015, holding in substantial part that EPA was not obligated to make a determination that numeric nutrient criteria are or are not necessary, provided EPA gives a reasonable explanation for its conclusion. The Court of Appeals remanded the case to the district court to decide whether EPA can meet that burden. On November 20, 2015, EPA filed a motion with the district court seeking summary judgment and on January 14, 2016, non-state intervenors including Mosaic filed a brief supporting EPA’s motion. In the event that EPA were to adopt numeric nutrient criteria for the Mississippi River basin and the Gulf of Mexico, we cannot predict what these requirements would be or the effects they would have on us or our customers.

•	We continue to monitor proposed regulations and policies prompted by the 2014 algal bloom in Lake Erie. We cannot predict the effects such initiatives might have to our operations or those of our customers.

•	Some of our mines are subject to potential damage from earthquakes.

•	Our underground potash shaft mines are subject to risk from fire. In the event of a fire, if our emergency procedures are not successful, we could have significant injuries or deaths. In addition, fire at one of our underground shaft mines could halt our operations at the affected mine while we investigate the origin of the fire or for longer periods for remedial work or otherwise.

•	We handle significant quantities of ammonia at several of our facilities. If our safety procedures are not effective, an accident involving our ammonia operations could result in serious injuries or death, or result in the shutdown of our facilities.

•	We also use or produce other hazardous or volatile chemicals at some of our facilities. If our safety procedures are not effective, an accident involving these other hazardous or volatile chemicals could result in serious injuries or death, or result in the shutdown of our facilities.

Nutrient Discharges into the Gulf of Mexico and Mississippi River Basin. On March 13, 2012, the Gulf Restoration Network, the Missouri Coalition for the Environment, the Iowa Environmental Council, the Tennessee Clean Water Network, the Minnesota Center for Environmental Advocacy, Sierra Club, the Waterkeeper Alliance, Inc., the Prairie Rivers Network, the Kentucky Waterways Alliance, the Environmental Law & Policy Center and the Natural Resources Defense Council, Inc. brought a lawsuit in the U.S. District Court for the Eastern District of Louisiana (the "Louisiana District Court") against EPA, seeking to require it to establish numeric nutrient criteria for nitrogen and phosphorous in the Mississippi River basin. In July 2011, EPA had denied the plaintiffs’ July 2008 petition seeking such standards. On May 30, 2012, the Louisiana District Court granted our motion to intervene in this lawsuit.

Includes grants of stock options, time-based restricted stock units, total shareholder return (“TSR”) performance units, and performance shares. For purposes of the table above, the number of shares to be issued under a TSR performance unit or performance share reflects the maximum number of shares of our common stock that may be issued pursuant to such TSR performance unit or performance share. The actual number of shares to be issued under a TSR performance unit will depend on the change in the market price of our common stock over a three-year vesting period, with no shares issued if the market price of a share of our common stock at the vesting date (plus, for grants made on and after July 18, 2012 dividends thereon), is less than 50% of its market price on the date of grant and the maximum number issued only if the market price of a share of our common stock at the vesting date (plus, for grants made on and after July 18, 2012, dividends thereon) is at least twice its market price on the date of grant. The actual number of shares to be issued under a performance share will depend on our achievement of controllable operating costs per tonne goals over a three-year performance period.

In May 2015, our Board of Directors authorized a $1.5 billion share repurchase program (the “2015 Repurchase Program”) allowing Mosaic to repurchase shares of our Common Stock, through open market purchases, accelerated share repurchase arrangements, privately negotiated transactions or otherwise. In connection with this authorization, the remaining amount of $149.4 million authorized under the $1.0 billion share repurchase program authorized in 2014 (the “2014 Repurchase Program”) was terminated. The extent to which we repurchase our shares and the timing of any such repurchases depend on a number of factors, including market and business conditions, the price of our shares, and corporate, regulatory and other considerations.

•	During 2015, an aggregate of 15,558,744 shares of Common Stock was repurchased under our repurchase programs for an aggregate of approximately $698.3 million.

(a)

Gross margin (excluding CRT), a non-GAAP measure, is calculated as GAAP gross margin less Canadian resource taxes. Gross margin (excluding CRT) as a percentage of net sales, also a non-GAAP measure, is calculated as GAAP gross margin plus Canadian resource taxes, divided by net sales. Gross margin (excluding CRT) and gross margin (excluding CRT) as a percentage of net sales provide measures that we believe enhance the reader's ability to compare our GAAP gross margin with that of other companies that incur Canadian resource tax expense and classify it in a manner different than we do in their statements of earnings. Because securities analysts, investors, lenders and others use gross margin, our management believes that our presentation of gross margin (excluding CRT) and gross margin (excluding CRT) as a percentage of sales for Potash affords them greater transparency in assessing our financial performance against competitors' gross margin (excluding CRT). A reconciliation of the GAAP and non-GAAP measures is found on page F-21.
