We also sell these products into the animal feed market as a nutritional supplement and sell potash into the industrial market as a component in drilling and fracturing fluids for oil and gas wells and other industrial inputs. In addition, we sell by-products including salt, magnesium chloride, and brine and other products such as water. </font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our extraction and production operations are conducted entirely in the continental United States. We produce potash from </font><font style="font-family:inherit;font-size:10pt;">three</font><font style="font-family:inherit;font-size:10pt;"> solution mining facilities: our HB solution mine in Carlsbad, New Mexico, our solution mine in Moab, Utah and our brine recovery mine in Wendover, Utah. We also operate our North compaction facility in Carlsbad, New Mexico, which compacts and granulates product from the HB mine. We produce Trio</font><font style="font-family:inherit;font-size:10pt;"><sup style="vertical-align:top;line-height:120%;font-size:7pt">®</sup></font><font style="font-family:inherit;font-size:10pt;"> from our conventional underground East mine in Carlsbad, New Mexico. Until mid-2016, we also produced potash from our East and West mines in Carlsbad, New Mexico. In April 2016, we converted our East facility from a mixed-ore facility that produced both potash and Trio</font><font style="font-family:inherit;font-size:10pt;"><sup style="vertical-align:top;line-height:120%;font-size:7pt">®</sup></font><font style="font-family:inherit;font-size:10pt;"> to a Trio</font><font style="font-family:inherit;font-size:10pt;"><sup style="vertical-align:top;line-height:120%;font-size:7pt">®</sup></font><font style="font-family:inherit;font-size:10pt;">‑only facility. In addition, in early July 2016, we idled mining operations at our West facility and transitioned the facility into care and maintenance. These changes were designed to increase our production of Trio</font><font style="font-family:inherit;font-size:10pt;"><sup style="vertical-align:top;line-height:120%;font-size:7pt">®</sup></font><font style="font-family:inherit;font-size:10pt;">, a product that had traditionally shown more resilience to pricing pressure than potash, and to lower costs in a time of declining potash prices.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We manage sales and marketing operations centrally. This allows us to evaluate the product needs of our customers and then centrally determine which of our production facilities to use to fill customer orders in a manner designed to realize the highest average net realized sales price per ton. Average net realized sales price per ton is a non-GAAP measure that we calculate by deducting freight costs from total sales and then by dividing this result by tons of product sold during the period. We also monitor product inventory levels and overall production costs centrally.</font></div></div>

We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results may differ significantly from these estimates under different assumptions or conditions. </font></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Significant estimates include, but are not limited to, those for proven and probable mineral reserves, the related present value of estimated future net cash flows, useful lives of plant assets, asset retirement obligations, normal inventory production levels, inventory valuations, the valuation of equity awards, the valuation of receivables, estimated future net cash flows used in long-lived assets impairment analysis, the related valuation of our long-lived assets, valuation of our deferred tax assets and estimated blended income tax rates utilized in the current and deferred income tax calculations. There are numerous uncertainties inherent in estimating quantities of proven and probable reserves, projecting future rates of production, and the timing of development expenditures. Future mineral prices may vary significantly from the prices in effect at the time the estimates are made, as may estimates of future operating costs. The estimate of proven and probable mineral reserves, the related present value of estimated future cash flows, and useful lives of plant assets can affect various other items including depletion, the net carrying value of our mineral properties, the useful lives of related property, plant, and equipment, depreciation expense, and estimates associated with recoverability of long-lived assets and asset retirement obligations. Specific to income tax items, we experience fluctuations in the valuation of the deferred tax assets and liabilities due to changing income tax rates and the blend of state tax rates.</font></div></div>
