These assets and liabilities must be recorded generally at the present value of the contracted lease payments, and the cost of the lease must be allocated over the lease term on a straight-line basis. This guidance is effective for us for annual and interim periods in fiscal years beginning after December 15, 2018. A modified retrospective transition method is required, applying the new standard to all leases existing at the date of initial application. We will adopt the new standard on January 1, 2019, and use the effective date as our date of initial application. Consequently, financial information will not be updated, and disclosures required under the new standard will not be provided for dates before January 1, 2019. </font></div><div style="line-height:120%;padding-bottom:8px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The new standard provides a number of optional practical expedients in transition. We have elected the use the package of practical expedients, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We have elected not to use the hindsight practical expedient nor the practical expedient pertaining to land easements.</font></div><div style="line-height:120%;padding-bottom:8px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">On adoption, we will recognize additional lease liabilities and right-of-use ("ROU") assets of approximately </font><font style="font-family:inherit;font-size:10pt;">$6.0 million</font><font style="font-family:inherit;font-size:10pt;">.</font></div><div style="line-height:120%;padding-bottom:8px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The new standard also provides practical expedients for our ongoing accounting. We have elected the short-term lease recognition exemption for all leases with an original term of 12 months or less. For leases that qualify for this exemption, we will not recognize ROU assets or lease liabilities. We have also elected the practical expedient which permits us to not separate lease and non-lease components for all our leases.</font></div><div style="line-height:120%;padding-bottom:8px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In June 2016, the FASB issued ASU No. 2016-13, </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Financial Instruments - (Topic 326): Measurement of Credit Losses on Financial Instruments</font><font style="font-family:inherit;font-size:10pt;">, which changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life. This guidance is effective for us for annual and interim periods in fiscal years beginning after December 15, 2018. Because we have historically experienced minimal bad debt expense related to our trade receivables, we do not believe the adoption of this new standard will have a material impact on our condensed consolidated financial statements.</font></div></div>

We are the only U.S. producer of muriate of potash (sometimes referred to as potassium chloride or potash), which is applied as an essential nutrient for healthy crop development, utilized in several industrial applications, and used as an ingredient in animal feed. In addition, we produce a specialty fertilizer, 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;">, which delivers three key nutrients, potassium, magnesium, and sulfate, in a single particle. We also provide water, magnesium chloride, brine and various oilfield products and services. </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 have water rights in New Mexico under which we sell water primarily to support oil and gas development in the Permian Basin near our Carlsbad facilities. We continue to work to expand our sales of water. On February 5, 2019, we and Sherbrooke Partners (together, the "buyers") entered into a purchase and sale agreement with Dinwiddie Cattle Company under which the buyers will purchase certain Dinwiddie Jal Ranch assets located in Lea County, New Mexico, consisting primarily of land, water rights and other related assets. The aggregate consideration for the purchase will be </font><font style="font-family:inherit;font-size:10pt;">$65 million</font><font style="font-family:inherit;font-size:10pt;">, subject to customary purchase price adjustments. Further, as additional consideration for the sale, buyers will grant certain royalties on saltwater disposal revenue relating to the purchased assets or properties located near the assets. We and Sherbrooke will pay </font><font style="font-family:inherit;font-size:10pt;">51%</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">49%</font><font style="font-family:inherit;font-size:10pt;"> of the purchase price, or approximately </font><font style="font-family:inherit;font-size:10pt;">$33.2 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">$31.8 million</font><font style="font-family:inherit;font-size:10pt;">, respectively, for a </font><font style="font-family:inherit;font-size:10pt;">51%</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">49%</font><font style="font-family:inherit;font-size:10pt;"> undivided interest in the assets, respectively. We expect to close the purchase in the first quarter of 2019, subject to the satisfaction of customary closing conditions. The buyers expect to enter into a joint development agreement with respect to the assets, pursuant to which the buyers will agree, among other things, that Intrepid will operate the assets.</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 have </font><font style="font-family:inherit;font-size:10pt;">three</font><font style="font-family:inherit;font-size:10pt;"> segments: potash, 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;">, and oilfield solutions. Prior to the fourth quarter of 2018, we had </font><font style="font-family:inherit;font-size:10pt;">two</font><font style="font-family:inherit;font-size:10pt;"> reporting segments; 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;">. As a result of the growth of our water business and other oilfield products and services, we reevaluated our segments and determined that, beginning in the fourth quarter of 2018, we have an additional segment for oilfield solutions. We account for the sales of byproducts as revenue in the potash or 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;">segment, base on which segment generates the byproduct. Prior to the adoption of Accounting Standards Codification ("ASC") Topic 606 </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue from Contract with Customers</font><font style="font-family:inherit;font-size:10pt;"> (ASC 606"), we accounted for the sale of byproducts as a credit to cost of goods sold. A majority of our byproduct sales were accounted for in the potash segment. We have recast the financial information for our segments for the years ended December 31, 2017, and 2016, to show the oilfield solutions segment and reclassification of byproduct sales to revenue.</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 for each of potash and Trio as segment sales less segment byproduct sales and segment freight costs, divided by the number of tons of product sold in the period. We also monitor product inventory levels and overall production costs centrally.</font></div></div>

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, revenue from products we sell to customers where the price is variable, 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>
