NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — COMPANY BACKGROUND

Intrepid Potash, Inc. (individually or in any combination with its subsidiaries, “Intrepid”) produces muriate of potash (“potassium chloride” or “potash”) and langbeinite. Langbeinite, which is marketed for sale as Trio^®, is a low-chloride potassium fertilizer with the additional benefits of sulfate and magnesium. Intrepid sells potash and Trio^® primarily into the agricultural market as a fertilizer. Intrepid also sells these products into the animal feed market as a nutritional supplement and sells potash into the industrial market as a component in drilling and fracturing fluids for oil and gas wells. In addition, Intrepid sells by-products including salt, magnesium chloride and metal recovery salts.

Intrepid owns five active potash production facilities: three in New Mexico, and two in Utah. Intrepid is constructing a sixth production facility, the HB Solar Solution mine, near Carlsbad, New Mexico. Intrepid has placed into service certain assets of the HB Solar Solution mine project, as it is already injecting brine into the production caverns and pumping potassium-rich brine into several of the newly constructed solar evaporation ponds.

Currently, production comes from two underground mines in the Carlsbad region of New Mexico; a solar evaporation solution mine near Moab, Utah; and a solar evaporation shallow brine mine in Wendover, Utah. Trio^® production comes from mining the mixed ore body that contains both potash and langbeinite, which is mined and processed at the East facility near Carlsbad, New Mexico. Intrepid manages sales and marketing operations centrally. This allows Intrepid to evaluate the product needs of its customers and then determine which of its production facilities to use to fill customers’ orders in a manner designed to realize the highest average net realized sales price to Intrepid. Intrepid calculates average net realized sales price by deducting freight costs from gross revenues and then by dividing this result by tons of product sold during the period. Intrepid also monitors product inventory levels and overall production costs centrally. Intrepid has one reporting segment being the extraction, production, and sale of potassium related products. Intrepid's extraction and production operations are conducted entirely in the continental United States.

Note 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation—The consolidated financial statements of Intrepid include the accounts of Intrepid and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates—The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Intrepid bases its 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.

Significant estimates include 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 derivative financial instruments, 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 Intrepid’s mineral properties, the useful lives of related property, plant, and equipment, estimates associated with asset retirement obligations, and depreciation expenses. Specific to income tax items, we tend to see significant fluctuations in the valuation of the deferred tax assets and liabilities due to changing state income tax rates and the blend of state tax rates.

Revenue Recognition—Revenue is recognized when evidence of an arrangement exists, risks and rewards of ownership have been transferred to customers, which is generally when title passes, the selling price is fixed and determinable, and collection is reasonably assured. Title passes at the designated shipping point for the majority of sales, but, in a few cases, title passes at the delivery destination. The shipping point may be the plant, a distribution warehouse, a customer warehouse, or a port. Title passes for some international shipments upon payment by the purchaser; however, revenue is not recognized for these transactions until shipment because the risks and rewards of ownership have transferred

6

pursuant to a contractual arrangement. Prices are generally set at the time of, or prior to, shipment. In cases where the final price is determined upon resale of the product by the customer, revenue is deferred until the final sales price is known.

Sales are reported on a gross basis. Intrepid quotes prices to customers both on a delivered basis and on the basis of pick-up at Intrepid’s plants and warehouses. When a sale occurs on a delivered basis, Intrepid incurs and, in turn, bills the customer and records as gross revenue the product sales value, freight, packaging, and certain other distribution costs. Many customers, however, arrange and pay for these costs directly and, in these situations, only the product sales are included in gross revenues.

By-product Credits—When by-product inventories are sold, Intrepid records the sale of by-products as a credit to cost of goods sold.

Inventory and Long-Term Parts Inventory—Inventory consists of product and by-product stocks that are ready for sale; mined ore; potash in evaporation ponds, which is considered work-in-process; and parts and supplies inventory. Product and by-product inventory cost is determined using the lower of weighted average cost or estimated net realizable value and includes direct costs, maintenance, operational overhead, depreciation, depletion, and equipment lease costs applicable to the production process. Direct costs, maintenance, and operational overhead include labor and associated benefits.

Intrepid evaluates its production levels and costs to determine if any should be deemed abnormal and therefore excluded from inventory costs and expensed directly during the applicable period. The assessment of normal production levels is judgmental and is unique to each period. Intrepid models normal production levels and evaluates historical ranges of production by operating plant in assessing what is deemed to be normal.

Parts inventory, including critical spares, that is not expected to be utilized within a period of one year is classified as non-current. Parts and supply inventory cost is determined using the lower of average acquisition cost or estimated replacement cost. Detailed reviews are performed related to the net realizable value of parts inventory, giving consideration to quality, slow-moving items, obsolescence, excessive levels, and other factors. Parts inventories not having turned-over in more than a year, excluding parts classified as critical spares, are reviewed for obsolescence and, if deemed appropriate, are included in the determination of an allowance for obsolescence.

Property, Plant, and Equipment—Property, plant, and equipment are stated at historical cost. Expenditures for property, plant, and equipment relating to new assets or improvements are capitalized, provided the expenditure extends the useful life of an asset or extends the asset’s functionality. Property, plant, and equipment are depreciated under the straight-line method using estimated useful lives. No depreciation is taken on assets classified as construction in progress until the asset is placed into service. Gains and losses are recorded upon retirement, sale, or disposal of assets. Maintenance and repair costs are recognized as period costs when incurred. Capitalized interest, to the extent of debt outstanding, is calculated and assigned to assets that are being constructed, drilled, or built or that are otherwise classified as construction in progress.

Recoverability of Long-Lived Assets—Intrepid evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amount may not be recoverable. An impairment is considered to exist if an asset’s total estimated net future cash flows on an undiscounted basis are less than the carrying amount of the related asset. An impairment loss is measured and recorded based on the discounted estimated future cash flows. Changes in significant assumptions underlying future cash flow estimates or fair values of assets may have a material effect on our financial position and results of operations.

Mineral Properties and Development Costs—Mineral properties and development costs, which are referred to collectively as mineral properties, include acquisition costs, the cost of drilling wells, and the cost of other development work, all of which are capitalized. Depletion of mineral properties is calculated using the units-of-production method over the estimated life of the relevant ore body. The lives of reserves used for accounting purposes are shorter than current reserve life determinations due to uncertainties inherent in long-term estimates. These reserve life estimates have been prepared by us and reviewed and independently determined by mine consultants. Tons of potash and langbeinite in the proven and probable reserves are expressed in terms of expected finished tons of product to be realized, net of estimated losses. Market price fluctuations of potash or Trio^®, as well as increased production costs or reduced recovery rates, could render proven and probable reserves containing relatively lower grades of mineralization uneconomic to exploit and might result in a reduction of reserves. In addition, the provisions of Intrepid’s mineral leases, including royalty provisions, are subject to periodic readjustment by the state and federal government, which could affect the economics of its reserve estimates. Significant changes in the estimated reserves could have a material impact on Intrepid’s results of operations and financial position.

Exploration Costs—Exploration costs include geological and geophysical work performed on areas that do not yet have proven and probable reserves declared. These costs are expensed as incurred.

7

Asset Retirement Obligation—Reclamation costs are initially recorded as a liability associated with the asset to be reclaimed or abandoned, based on applicable inflation assumptions and discount rates. The accretion of this discounted liability is recognized as expense over the life of the related assets, and the liability is periodically adjusted to reflect changes in the estimates of either the timing or amount of the reclamation and abandonment costs.

Planned Turnaround Maintenance—Each production operation typically shuts down periodically for planned maintenance activities. The costs of maintenance turnarounds at Intrepid's facilities are considered part of production costs and are absorbed into inventory in the period incurred.

Leases—Upon entering into leases, Intrepid evaluates whether leases are operating or capital leases. Operating lease expense is recognized as incurred. If lease payments change over the contractual term or involve contingent amounts, the total estimated cost over the term is recognized on a straight-line basis.

Income Taxes—Intrepid is a subchapter C corporation and therefore is subject to U.S. federal and state income taxes. Intrepid recognizes income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the periods in which the deferred tax liability or asset is expected to be settled or realized. Intrepid records a valuation allowance if it is deemed more likely than not that its deferred income tax assets will not be realized in full. These determinations are subject to ongoing assessment.

Cash and Cash Equivalents—Cash and cash equivalents consist of cash and liquid investments with an original maturity of three months or less.

Investments—Intrepid’s short-term and long-term investments consist of certificates of deposit with various banking institutions, municipal tax-exempt and corporate taxable bonds, and corporate convertible debentures, which have been classified as either held-to-maturity or available-for-sale securities. Short-term investments on the consolidated balance sheets have remaining maturities to Intrepid less than or equal to one year and investments classified as long-term on the consolidated balance sheets have remaining maturities to Intrepid greater than one year. With regard to the financial instruments classified as held-to-maturity investments, they are carried on the consolidated balance sheets at cost, net of amortized premiums or discounts paid. The available-for-sale securities are carried at fair value, with changes in fair value recognized through "Other Comprehensive Loss" on the condensed consolidated balance sheets. Fair value is assessed using a market‑based approach.

Fair Value of Financial Instruments—Intrepid’s financial instruments include cash and cash equivalents, certificate of deposit investments, short-term and long-term investments, restricted cash, accounts receivable, income tax receivables, and accounts payable, all of which are carried at cost, except for available-for-sale investments which are carried at fair value. The remaining investments approximate fair value due to the short-term nature of these instruments. Allowances for doubtful accounts are recorded against the accounts receivable balance to estimate net realizable value. Although there are no amounts currently outstanding under Intrepid’s unsecured credit facility, any borrowings that become outstanding are expected to be recorded at amounts that approximate their fair value as borrowings bear interest at a floating rate.

In April 2013, Intrepid issued $150 million aggregate principal amount of unsecured senior notes ("the Notes"). The Notes bear interest at fixed rates and are deemed to be financial instruments. Accordingly, the fair value of the Notes will be determined on a periodic basis and disclosed. Since considerable judgment is required to develop estimates of fair value, the estimates provided are not necessarily indicative of the precise amounts that could be realized upon the sale, settlement, or refinancing of the instruments.

Earnings per Share—Basic net income per common share of stock is calculated by dividing net income available to common stockholders by the weighted average basic common shares outstanding for the respective period.

Diluted net income per common share of stock is calculated by dividing net income by the weighted average diluted common shares outstanding, which includes the effect of potentially dilutive securities. Potentially dilutive securities for the diluted earnings per share calculation consist of awards of non-vested restricted shares of common stock, non-vested performance units, and non-qualified stock options. The dilutive effect of stock based compensation arrangements are computed using the treasury stock method. Following the lapse of the vesting period of restricted shares of common stock, the shares are considered issued and therefore are included in the number of issued and outstanding shares for purposes of these calculations.

Stock‑Based Compensation—Intrepid accounts for stock-based compensation by recording expense using the fair value of the awards at the time of grant. Intrepid has recorded compensation expense associated with the issuance of non-vested restricted shares of common stock, non-vested performance units, and non-qualified stock options, all of which are

8

subject to service conditions. The expense associated with such awards is recognized over the service period associated with each issuance. Performance units are also subject to operational performance- or market-based conditions.

Note 3 — EARNINGS PER SHARE

The treasury stock method is used to measure the dilutive impact of non-vested restricted shares of common stock and outstanding stock options. For the three months ended March 31, 2013, and 2012, a weighted average of 40,314 and 76,705 non-vested shares of restricted common stock and 244,755 and 176,862 stock options, respectively, were anti-dilutive and therefore were not included in the diluted weighted average share calculation. For the three months ended March 31, 2012, 2,072 shares of common stock underlying non-vested performance units were anti-dilutive and therefore were not included in the diluted weighted average share calculation. The following table sets forth the calculation of basic and diluted earnings per share (in thousands, except per share amounts):

	Three Months Ended March 31,

Total cash, cash equivalents, and investments	$	7,612	$	57,747

As of December 31, 2012, $17.6 million of investments were classified as available-for-sale securities. As of March 31, 2013, no investments were classified as available-for-sale. The net unrealized loss on these securities of approximately $29,000 is reflected in accumulated other comprehensive income as of December 31, 2012.

Note 5 — INVENTORY AND LONG-TERM PARTS INVENTORY

The following summarizes Intrepid’s inventory, recorded at the lower of weighted average cost or estimated net realizable value, as of March 31, 2013, and December 31, 2012, respectively (in thousands):

Note 7 — DEBT

Unsecured Credit Facility— Intrepid has an unsecured credit facility, led by U.S. Bank, as administrative agent, and Wells Fargo Bank, as syndication agent. This unsecured credit facility provides a total revolving credit facility of $250 million with a five-year term through August 2016. The facility is unsecured and is guaranteed by certain material

10

subsidiaries of Intrepid, as defined in the agreement governing the facility. There were no amounts outstanding under the facility as of March 31, 2013, or December 31, 2012.

Unsecured Senior Notes—In April 2013, Intrepid issued $150 million aggregate principal amount of the Notes pursuant to a note purchase agreement entered into in August 2012. Intrepid received proceeds of $149.3 million, net of offering costs. The Notes consist of the following series:

• $60 million of 3.23% Senior Notes, Series A, due April 16, 2020

• $45 million of 4.13% Senior Notes, Series B, due April 14, 2023

• $45 million of 4.28% Senior Notes, Series C, due April 16, 2025

The Notes are senior unsecured obligations of Intrepid and rank equally in right of payment with any other unsubordinated unsecured indebtedness of Intrepid. The obligations under the Notes are unconditionally guaranteed by Intrepid's material subsidiaries. Interest on the Notes began accruing on April 16, 2013, the date the Notes were issued. Interest will be paid semiannually on April 16 and October 16 of each year, beginning on October 16, 2013. Interest expense will be recorded net of any capitalized interest associated with investments in capital projects. The fair value of the Notes will be estimated using discounted cash flow analysis based on current borrowing rates for debt with similar conditions, remaining maturities and ratings (a Level 2 input), as appropriate.

Note 8 — ASSET RETIREMENT OBLIGATION

Intrepid recognizes an estimated liability for future costs associated with the abandonment and reclamation of its mining properties. A liability for the fair value of an asset retirement obligation and a corresponding increase to the carrying value of the related long-lived asset are recorded as the mining operations occur or the assets are acquired.

Intrepid’s asset retirement obligation is based on the estimated cost to abandon and reclaim the mining operations, the economic life of the properties, and federal and state regulatory requirements. The liability is discounted using credit adjusted risk-free rate estimates at the time the liability is incurred or when there are upward revisions to estimated costs. The credit adjusted risk-free rates used to discount Intrepid’s abandonment liabilities range from 6.9% to 8.5%. Revisions to the liability occur due to construction of new or expanded facilities, changes in estimated abandonment costs or economic lives, or if federal or state regulators enact new requirements regarding the abandonment of mines.

Following is a table of the changes to Intrepid’s asset retirement obligations for the following periods (in thousands):

	Three Months Ended March 31,
	2013			2012
Asset retirement obligation, at beginning of period	$	20,579		$	9,708
Liabilities settled	(24		)	(273		)
Liabilities incurred	184			—
Accretion of discount	375			181
Total asset retirement obligation, at end of period	$	21,114		$	9,616

The current portion of asset retirement obligations of $1.2 million was included in "Other" current liabilities on the condensed consolidated balance sheets as of March 31, 2013, and December 31, 2012. The undiscounted amount of asset retirement obligation is $53.0 million as of March 31, 2013, of which Intrepid estimates approximately $8.8 million in payments may occur in the next five years.

Note 9 — COMPENSATION PLANS

Cash Bonus Plan—Intrepid has cash bonus plans that allow participants to receive varying percentages of their aggregate base salary. Any awards under the cash bonus plans are based on a variety of elements related to Intrepid’s performance in certain production, operational, financial, and other areas, as well as the participants’ individual performance. Intrepid accrues cash bonus expense related to the current year’s performance.

Equity Incentive Compensation Plan—Intrepid's Board of Directors and stockholders have adopted a long-term incentive compensation plan called the Intrepid Potash, Inc. Equity Incentive Plan, as Amended and Restated (the "Plan").

11

Intrepid has issued common stock, restricted shares of common stock, performance units, and non-qualified stock option awards under the Plan. As of March 31, 2013, there were a total of 379,621 shares of non-vested restricted shares of common stock, 97,367 non-vested performance units representing shares of common stock, and options to purchase 344,563 shares of common stock. As of March 31, 2013, there were approximately 3.6 million shares of common stock that remain available for issuance under the Plan.

Common Stock

On an annual basis, under the Plan, the Compensation Committee of the Board of Directors (the "Compensation Committee") approves the award of shares of common stock to the non-employee members of the Board of Directors as compensation for service for the period ending on the date of Intrepid’s annual stockholders’ meeting for the following year. These shares of common stock were granted without restrictions and vested immediately.

Non-vested Restricted Shares of Common Stock

Under the Plan, grants of non-vested restricted shares of common stock have been awarded to executive officers, other key employees, and consultants. The awards contain service conditions associated with continued employment or service. There are no performance or market conditions associated with these awards. The terms of the non-vested restricted shares of common stock provide voting and regular dividend rights to the holders of the awards. Upon vesting, the restrictions on the restricted shares of common stock lapse, and the shares are considered issued and outstanding.

Since 2009, the Compensation Committee has granted restricted shares of common stock under the Plan in the first quarter of each year to Intrepid's executive management team and other selected employees as part of an annual equity award program. These awards vest ratably over three years. From time to time, the Compensation Committee grants restricted shares of common stock to newly hired or promoted employees or other employees or consultants who have achieved extraordinary personal performance objectives. These restricted shares of common stock generally vest over one- to four-year periods.

In measuring compensation expense associated with the grant of non-vested restricted shares of common stock, Intrepid uses the fair value of the award, determined as the closing stock price for Intrepid’s common stock on the grant date. Compensation expense is recorded monthly over the vesting period of the award. Total compensation expense related to the non-vested restricted shares of common stock awards for both the three months ended March 31, 2013, and 2012, was $0.8 million. These amounts are net of estimated forfeiture adjustments. As of March 31, 2013, there was $7.9 million of total remaining unrecognized compensation expense related to non-vested restricted shares of common stock that will be expensed through 2015.

A summary of activity relating to Intrepid’s non-vested restricted shares of common stock for the three months ended March 31, 2013, is presented below.

			Weighted Average Grant-Date Fair Value
	Shares
Non-vested restricted shares of common stock, beginning of period	240,757		$	26.04
Granted	232,336		$	19.26
Vested	(88,186	)	$	27.12
Forfeited	(5,286	)	$	21.60
Non-vested restricted shares of common stock, end of period	379,621		$	21.70

Performance Units

Since 2012, the Compensation Committee has granted performance units under the Plan to certain members of Intrepid's executive management team as part of the annual equity award program. The Compensation Committee issued two types of performance units: an operational performance-based award and a market condition-based award. The awards contain service conditions associated with continued employment, as well as an operational performance or market condition. The operational performance conditions are based on tons of potash and Trio^® produced, and the market conditions are based on Intrepid's stock performance relative to a peer group and a broad market index. As of March 31, 2013, the maximum number of shares of common stock that may be issued, pending satisfaction of the operational performance or market condition and continued employment is 97,367 shares of common stock. These performance shares are subject to vesting

12

conditions that provided for issuance over a three-year period assuming continued employment by the individual grantees through the vesting dates. For the three months ended March 31, 2013, Intrepid recognized stock‑based compensation related to performance units of approximately $0.1 million. As of March 31, 2013, there was $1.2 million of total remaining unrecognized compensation expense related to unvested performance units that will be expensed through 2015.

Non-qualified Stock Options

From 2009 to 2011, the Compensation Committee issued non-qualified stock options under the Plan in the first quarter of each year to Intrepid’s executive management and other selected employees as part of its annual award program. These stock options generally vest ratably over three years. In measuring compensation expense for this grant of options, Intrepid estimated the fair value of the award on the grant date using the Black‑Scholes option valuation model. Option valuation models require the input of highly subjective assumptions, including the expected volatility of the price of the underlying stock.

For the three months ended March 31, 2013, and 2012, Intrepid recognized stock‑based compensation related to previously issued stock options of approximately $0.2 million and $0.4 million, respectively. As of March 31, 2013, there was $0.6 million of total remaining unrecognized compensation expense related to unvested non-qualified stock options that will be expensed through 2013 and 2014. Realized tax benefits from tax deductions for exercised options in excess of the deferred tax asset attributable to stock compensation for such options are regarded as “excess tax benefits.”

A summary of Intrepid’s stock option activity for the three months ended March 31, 2013, is as follows:

	Shares	Weighted Average Exercise Price	Aggregate Intrinsic Value (1)	Weighted Average Remaining Contractual Life	Weighted Average Grant-Date Fair Value
Outstanding non-qualified stock
options, end of period	344,563	$26.25	$—	6.6	$13.13
Vested or expected to vest, end
of period	341,514	$26.17	$—	6.6	$13.07
Exercisable non-qualified
stock options, end of period	313,294	$25.31	$—	6.6	$12.49

(1) The intrinsic value of a stock option is the amount by which the market value exceeds the exercise price as of the end of the period presented.

Note 10 — INCOME TAXES

Intrepid’s effective tax rate was 36.8% and 37.9% for the three months ended March 31, 2013, and 2012, respectively. Intrepid's effective tax rate is impacted primarily by the amount of taxable income associated with each jurisdiction in which Intrepid's income is subject to income tax, permanent differences between the financial statement carrying amounts and tax bases of assets, liabilities, and the benefit associated with the estimated domestic production activities deduction. A summary of the provision for income taxes is as follows (in thousands):

	Three Months Ended March 31,
	2013		2012
Current portion of income tax expense	317		2,622
Deferred portion of income tax expense	8,381		9,991
Total income tax expense	$	8,698	$	12,613

The blended state tax rate applied to the deferred tax calculation is subject to change due to changes in state laws and changes in the mix of Intrepid's business and the states in which Intrepid has a taxable relationship. This creates

13

fluctuations in the value of Intrepid's net deferred tax asset. In April 2013, the state of New Mexico lowered its corporate income tax rate pursuant to a schedule that goes into effect over the next five years. Intrepid has estimated that the lower state income tax rates will result in a relatively lower future income tax expense. Further, Intrepid will record increased deferred state income tax expense in the three months ended June 30, 2013, as its deferred tax asset will have decreased in value. The estimated impact of this change on Intrepid's net deferred income tax value is currently estimated to be between $1.0 million and $1.4 million. The actual timing for the use of the deferred income tax asset will be based on the actual taxable income earned over future periods and will likely be different from the current estimate.

Note 11 — COMMITMENTS AND CONTINGENCIES

Marketing Agreements—Intrepid has a marketing agreement appointing PCS Sales (USA), Inc. (“PCS Sales”) as its exclusive sales representative for potash export sales, with the exception of sales to Canada and Mexico, and appointing PCS Sales as its non-exclusive sales representative for potash sales into Mexico. Trio^® is also marketed under this arrangement. This agreement is cancelable with 30 days' written notice.

Intrepid has a sales agreement with an entity appointing such entity as the exclusive distributor, subject to certain conditions, for magnesium chloride produced by Wendover, with the exception of up to 15,000 short tons per year sold for applications other than dust control, de-icing, and soil stabilization. This agreement is cancelable with two years’ written notice, unless a breach or other specified special event has occurred. Sales prices were specified to the entity in the agreement subject to cost-based escalators. Intrepid is also entitled to certain adjustments in the sale price to the entity based on the final sales price it receives from its customers, as defined by the agreement. Any adjustments in sales price are settled after the entity's fiscal year end in September; however, Intrepid estimates and recognizes earned sales price adjustments each quarter as the amounts are earned and reasonably determinable.

Reclamation Deposits, Surety Bonds, and Sinking Fund—As of March 31, 2013, Intrepid had $17.3 million of security placed principally with the State of Utah and the Bureau of Land Management for eventual reclamation of its various facilities. Of this total requirement, $0.5 million consisted of long-term restricted cash deposits reflected in “Other” non-current assets on the condensed consolidated balance sheets, and $16.8 million was secured by surety bonds issued by an insurer. The surety bonds are held in place by an annual fee paid to the issuer.

Intrepid may be required to post additional security to fund future reclamation obligations as reclamation plans are updated or as governmental entities change requirements.

Legal— Intrepid is subject to litigation. Intrepid has determined that there are no material claims outstanding as of March 31, 2013. Intrepid has established a legal reserve for loss contingencies that are considered probable and reasonably estimable.

Future Operating Lease Commitments—Intrepid has certain operating leases for land, mining and other operating equipment, an airplane, offices, and railcars, with original terms ranging up to 20 years.

Rental and lease expenses follow for the indicated periods (in thousands):

For the three months ended March 31, 2013	$909
For the three months ended March 31, 2012	$836

Note 12 — DERIVATIVE FINANCIAL INSTRUMENTS

Intrepid is exposed to global market risks, including the effect of changes in commodity prices and interest rates. From time to time, Intrepid uses derivatives to manage financial exposures that occur in the normal course of business. Intrepid does not enter into or hold derivatives for trading purposes. While all derivatives had been used for risk management purposes, and were originally entered into as economic hedges, they had not been designated as hedging instruments.

Natural Gas

From time to time, Intrepid manages a portion of its exposure to movements in the market price of natural gas through the use of natural gas derivative contracts. Intrepid had no natural gas derivative contracts outstanding at March 31, 2013.

14

Interest Rates

Prior to Intrepid's initial public offering in April 2008, Intrepid's predecessor historically managed a portion of its floating interest rate exposure on outstanding debt through the use of interest rate derivative contracts, as required by its credit agreement. Intrepid repaid its assumed debt obligations immediately subsequent to the closing of its initial public offering and, in the year ended December 31, 2012, settled in the ordinary course of business its positions in the derivative financial instruments also assumed from its predecessor.

The following table presents the amounts of gain or (loss) recognized in income on derivatives affecting the condensed consolidated statement of operations for the periods presented (in thousands):

	Location of gain (loss) recognized in income on derivative	Three Months Ended March 31,
Derivatives not designated as hedging instruments		2012
Interest rate contracts:
Realized loss	Interest expense	$	(266	)
Unrealized gain	Interest expense	224
Total loss	Interest expense	$	(42	)

Please see footnote titled Fair Value Measurements, for a description of how the above financial instruments are valued.

Note 13 — FAIR VALUE MEASUREMENTS

Intrepid applies the provisions of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification™ (“ASC”) Topic 820, Fair Value Measurements and Disclosures, for all financial assets and liabilities measured at fair value on a recurring basis. The topic establishes a framework for measuring fair value and requires disclosures about fair value measurements. ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The topic establishes market or observable inputs as the preferred sources of values, followed by assumptions based on hypothetical transactions in the absence of market inputs. The topic also establishes a hierarchy for grouping these assets and liabilities, based on the significance level of the following inputs:

• Level 1—Quoted prices in active markets for identical assets and liabilities.

• Level 2—Quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar instruments in markets that are not active, and model‑derived valuations whose inputs are observable or whose significant value drivers are observable.

• Level 3—Significant inputs to the valuation model are unobservable.

As of March 31, 2013, Intrepid did not have any assets or liabilities that were required to be measured at fair value. The following is a listing of Intrepid’s assets and liabilities required to be measured at fair value on a recurring basis and where they are classified within the hierarchy as of December 31, 2012 (in thousands):

15

			Fair Value at Reporting Date Using
	December 31, 2012		Quoted Prices in Active Markets for Identical Assets or Liabilities (Level 1)		Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Investments
Corporate bonds	$	17,462	$	—	$	17,462	$	—
Certificate of deposit	$	166	$	—	$	166	$	—

Financial assets or liabilities are categorized within the hierarchy based upon the lowest level of input that is significant to the fair value measurement. Below is a general description of Intrepid’s valuation methodologies for financial assets and liabilities, which are measured at fair value and are included in the accompanying condensed consolidated balance sheets.

Intrepid's available-for-sale investments consist of corporate bonds and certain certificates of deposits that are valued using Level 2 inputs. Market pricing for these investments is obtained from an established financial markets data provider.

The methods described above may result in a fair value estimate that may not be indicative of net realizable value or may not be reflective of future fair values and cash flows. While Intrepid believes that the valuation methods utilized are appropriate and consistent with the requirements of ASC Topic 820 and with other marketplace participants, Intrepid recognizes that third parties may use different methodologies or assumptions to determine the fair value of certain financial instruments that could result in a different estimate of fair value at the reporting date.

Note 14 — EMPLOYEE BENEFITS

Defined Benefit Pension Plan—In accordance with the terms of the Moab Purchase Agreement associated with the purchase of the assets relating to its Moab facility in 2000, Intrepid and its predecessor established the Moab Salt, L.L.C. Employees’ Pension Plan (“Pension Plan”), a defined benefit pension plan. Pursuant to the terms of the Moab Purchase Agreement, employees transferring from the acquiree to Intrepid were granted credit under the Pension Plan for their prior service and for the benefits they had accrued under the acquiree’s pension plan, and approximately $1.5 million was transferred from the acquiree’s pension plan to the Pension Plan to accommodate the recognition of these prior services and benefits. In February 2002, Intrepid froze the benefits to be paid under the Pension Plan by limiting participation in the Pension Plan solely to employees hired before February 22, 2002, and by including only pay and service through February 22, 2002, in the calculation of benefits.

In December 2011, Intrepid adopted resolutions to terminate the Pension Plan. Prior to Intrepid's Pension Plan liability being fully funded, certain regulatory approvals, plan amendments and participant settlement elections needed to be obtained. In April 2013, Intrepid funded $2.0 million to settle all Pension Plan liabilities. Intrepid will record an additional expense of approximately $1.9 million to reflect the termination of the Pension Plan in the second quarter of 2013. This amount will be recorded as "Other expense" in the condensed consolidated statement of operations and represents the difference between the final amount funded, the recorded pension liability and the unrecognized actuarial loss included in accumulated other comprehensive income. The components of the net periodic pension expense are set forth below (in thousands):

	Three Months Ended March 31,
	2013			2012
Components of net periodic benefit cost:
Interest cost	$	21		$	23
Amortization of prior service cost	(4		)	(4		)
Amortization of actuarial loss	75			61
Net period benefit cost	$	92		$	80

Note 15 — RECENT ACCOUNTING PRONOUNCEMENTS

In February 2013, FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting these reclassifications. This ASU expands the presentation of changes in accumulated other comprehensive income. The new guidance requires an entity to disaggregate the total change of each component of other comprehensive income either on the face of the net income statement or as a separate disclosure in the notes. ASU 2013-02 is effective for fiscal years beginning after December 15, 2012. The adoption of this ASU did not have a significant impact on its consolidated financial position, results of operations or cash flows.

Our Company

We are the largest producer of muriate of potash (“potassium chloride” or “potash”) in the United States and are one of two producers of langbeinite (“sulfate of potash magnesia”). Langbeinite is a low-chloride potassium fertilizer with the additional benefits of sulfate and magnesium. We generally describe this multi-nutrient specialty product as langbeinite when we refer to production and as Trio^® when we refer to sales and marketing. Our revenues are generated exclusively from the

18

sale of potash and Trio^®. Potassium is one of the three primary macronutrients essential to plant formation and growth. Since 2005, we have supplied, on average, approximately 1.5% of annual world potassium consumption and 9.2% of annual U.S. potassium consumption. We also produce salt and magnesium chloride from our potash mining processes, the sales of which are accounted for as by-product credits to our cost of sales.

Our potash is marketed for sale into three primary markets, which are the agricultural market as a fertilizer input, the industrial market as a component in drilling and fracturing fluids for oil and gas wells, and the animal feed market as a supplemental nutrient. The agricultural market is predominately a user of granular-sized potash and Trio^®, while the industrial and animal feed markets largely consume standard and fine standard-sized product. The flexibility to compact a greater percentage of our production in granular form allows us to meet demand and maximize our average net realized sales price. Our investments in granulation capacity have allowed us to expand our geographical reach for granular product sales that would otherwise be unavailable. This flexibility also allows us to adjust our production to more closely align with the specific markets, thereby decreasing our dependence on sales of any one particular size of potash.

Our sales of potash tend to focus on agricultural areas, feed manufacturers in the central and western United States, and oil and gas drilling areas in the Rocky Mountains and the greater Permian Basin area. We also have domestic sales, primarily of Trio^®, in the southeastern and eastern United States, with a focus on areas with specific agricultural nutrition requirements. We manage our sales and marketing operations, including our freight and logistics planning, centrally. This allows us to evaluate the product needs of our customers and then determine which of our production facilities can be used to fill customer orders, all with the design of realizing the highest average net realized sales price for our potash.

We own five active potash production facilities—three in New Mexico (referenced collectively below as “Carlsbad” or individually as “West,” “East,” and “North”) and two in Utah (“Moab” and “Wendover”). We have a current estimated annual productive capacity of approximately 900,000 tons of potash, not including 200,000 tons of designed productive capacity for the HB Solar Solution mine described below, and approximately 240,000 tons of langbeinite, based on current design. We are not yet producing at an annual rate of 240,000 tons per year of langbeinite. Actual production is affected by operating rates, recoveries, mining rates, precipitation, and evaporation rates at our solar solution operations, and the amount of development work that we perform. Therefore, our production results tend to be lower than our productive capacity. We have an additional solar solution mine that is under construction in Carlsbad, New Mexico, called the HB Solar Solution mine. We are constructing the HB Solar Solution mine, a project to apply solution mining and solar evaporation techniques to produce potash from previously idled mine workings close to our current underground operations near Carlsbad, New Mexico. We have additional opportunities to develop mineralized deposits of potash in New Mexico. These opportunities could include one or more of the following: additional solution mining activities; improved recovery methods on existing ore; and potential acceleration of the development of reserves using the North mine infrastructure, which was operated as a traditional underground mine until the early 1980s.

We routinely post important information about Intrepid and our business, including information about upcoming investor presentations, on our website under the Investor Relations tab. We encourage investors and other interested parties to enroll on our website to receive automatic email alerts or Really Simple Syndication (RSS) feeds regarding new postings. Our website is www.intrepidpotash.com.

Significant Business Trends and Activities

Our financial results are impacted by several significant trends, which are described below. We expect that these trends will continue to drive our results of operations, cash flows, or financial position.

• Potash demand. We sold 185,000 tons of potash in the first quarter of 2013, compared to 203,000 tons of potash sold during the first quarter of 2012. Seasonal weather conditions were the primary driver of the difference in sales volumes between the two periods. During the first quarter of 2013, our sales were impacted by cooler soil temperatures, extended winter conditions in the Northern plains of the United States, and some concern over the drought conditions in certain areas of the country. In comparison, the first quarter of 2012 experienced warmer and drier conditions, which allowed an earlier start to spring planting season. The economic outlook continues to be favorable for farmer economics in 2013 with continued tight grain stocks, supportive grain prices, and strong acreage planting intentions. As a result, we expect potash demand in North America will be in line with historical levels for the spring planting season. However, if the cool and wet conditions in the central parts of United States extend much longer, the spring planting season may become further compressed or even restrict the acres of crops that are planted and therefore the amount of potash that is applied.

As is typically the case, the specific month in which farmers apply potash remains weather dependent and varies by the numerous growing regions across the United States. In addition, potash demand is significantly influenced by dealer storage volumes and marketing programs that are advantageous to the potash retailers. The combination of these items

results in recurring variability in potash shipments from our production facilities, thereby increasing volatility of sales volumes from quarter to quarter.

• Potash prices. Potash prices are a significant driver of profitability for our business. Our average net realized sales price decreased to $417 per ton in the first quarter of 2013 from $477 in the first quarter of 2012. This decrease is due to the continued downward pressure on potash prices caused by concern around increased global potash supply. Uncertainty around global potash sales levels, especially into large international markets, such as China and India, also puts pressure on domestic potash prices. Some North American producers reacted to this demand volatility by curtailing production during the latter half of 2012 and into 2013. When demand from China and India became clearer, the Canadian producers began to increase production in the first quarter of 2013. Despite the curtailments during 2012, North American producers increased their inventory levels into the end of 2012 and, as a result, we have experienced greater price competition in North America. This pressure on potash prices and ongoing uncertainty in the world economy continues to cloud the long-term global potash market. As additional brownfield potash production is brought on-line globally, this new production could cause further price erosion absent increases in global potash consumption. In the near term, we expect North American demand to be steady and pricing to be stable, within a range, through the 2013 spring season.

• Trio^® prices and demand. The average net realized sales price of Trio^® has increased to $351 per ton in the first quarter of 2013 from $302 per ton in the first quarter of 2012. We continue to have strong demand for all sizes of our Trio^® product. Trio^® domestic pricing has historically tended to move in a relatively close correlation to potash, although, over the last year, dealers' and farmers' recognition of the added value of magnesium and sulfate from this specialty product has translated into higher prices despite sequentially lower potash prices. Demand in excess of production has also been supportive of Trio^® pricing. Export Trio^® pricing continues to show strength as international customers see value for Trio^®. Trio^® sales in 2013 are expected to essentially match production levels due to the low inventory levels we have available for sale.

• Construction of the HB Solar Solution mine and North compaction facility. We are making significant progress on the construction of the HB Solar Solution mine. We have completed all of the drilling activities associated with the injection and extraction wells and pipelines that were contemplated in the initial design. Construction of the solar evaporation ponds continues to advance, and we have pumped potash-enriched brine from the underground mines into several of the completed evaporation ponds. In addition, construction of the processing plant progressed in the first quarter of 2013 as scheduled and is expected to be completed in the fourth quarter of 2013. The total expected investment for the project is between $225 million and $245 million, of which $151.2 million had been invested as of March 31, 2013.

The construction of the new North Compaction facility is also progressing with $72.6 million of the expected $95 million to $100 million investment made as of March 31, 2013. This new facility expands our granulation capacity to accommodate the increased tonnage expected from the HB Solar Solution mine and ongoing expansions at our West mine. The new facility will utilize state-of-the-art equipment providing us the tools to provide high quality granular production from this facility.

• Operating efficiencies at the East facility. We have dedicated significant resources to the long-term improvement plan that we implemented in the beginning of 2012 to address production challenges at the East facility. Execution of the long-term improvement plan is expected to continue throughout 2013. We have seen steady and measurable improvement as we execute the plan. Our potash production at the East facility increased each quarter in 2012 and has leveled off at historical production rates in the first quarter of 2013. The increased production from East contributed to our improved per ton total potash cash operating cost of goods sold. More recently, our quarterly langbeinite production level increased to 46,000 tons in the first quarter of 2013, representing the highest quarterly production level in over two years. We expect langbeinite production levels in 2013 to be greater than those in 2012, as a result of the improvement plan. The benefit of this increased productivity is directly reflected in the improved profitability associated with Trio^® with average Trio^® gross margin improving to $85 per ton in the first quarter of 2013 compared to negative $9 per ton in the same period in 2012.

Selected Operating and Financial Data

The following table presents selected operations data for the periods noted. Analysis of the details of this information is contained throughout this discussion. We present this table as a summary of information relating to key indicators of financial condition and operating performance that we believe are important. We calculate average net realized sales price by deducting freight costs from gross revenues and then by dividing this result by tons of product sold during the period.

Results of Operations

Operating Highlights

Net income in the first quarter of 2013 was $14.9 million, or $0.20 per share, with cash flows from operations of $11.6 million. During the quarter ended March 31, 2013, we sold 185,000 tons of potash at a net realized sales price of $417 per ton and 39,000 tons of Trio^® at a net realized sales price of $351 per ton. We made capital investments of $64.2 million in the first quarter of 2013 and ended the quarter with $7.6 million of cash and investments and no debt outstanding. We produced 222,000 tons of potash and 46,000 tons of Trio^® in the quarter ended March 31, 2013.

Potash

In the first quarter of 2013, we sold 185,000 tons of potash as compared to 203,000 tons in the first quarter of 2012. Our sales of potash in the first quarter of 2013, as compared to the first quarter a year ago, were impacted by the weather conditions described above, which delayed farmers from performing work in the fields. Our average net realized sales price of potash was $417 per ton in the first quarter of 2013, compared with $477 per ton in the first quarter of 2012. This decrease is due to the impact of the recent increases in global production capacity for potash combined with the timing of the global demand for potash. These global factors in turn had a directional impact on North American pricing, thereby lowering our average net realized sales price.

The percentage of our sales in each of the markets we serve stayed relatively consistent from the first quarter of 2012 to the same period in 2013. The slight percentage change in the markets we serve is mainly due to the weather conditions for our agricultural sales which caused a delay in certain agricultural purchases in the first quarter of 2013 compared with the first quarter of 2012.

Our potash sales mix was as follows for the indicated periods.

	Three Months Ended March 31,
	2013		2012
Agricultural	79	%	81	%
Industrial	14	%	12	%
Feed	7	%	7	%

The flexibility to produce as much granular-sized product as we need is important as we continue to see long-term trends that support utilization of potash in agriculture. Data generated by Fertecon Limited, a fertilizer industry consultant, shows that over the past 25 years, the domestic consumption of potash has averaged approximately 9.3 million tons with annual volatility of approximately 10%. These results have occurred through historical periods of low and high agricultural commodity prices, weather conditions, variability in oil and gas drilling, negative farmer margins, and a variety of other macro-economic factors. Continuing improvements in agriculture production technology, such as hybrid seeds and equipment advancements, now allow for the potential of higher yields per acre. These improvements need to be matched with potassium application rates to maximize agricultural productivity. We believe these factors suggest increased domestic potash consumption is possible in the coming years.

The replacement of potassium in the soil is critical to continue high-yielding agricultural production and to satisfy the demands placed on soils for plant nutrition. The International Plant Nutrition Institute has tracked historical soil potassium levels and trends show an increase of potassium deficient agricultural soils in North America, suggesting that there is less of a buffer built into the soil associated with potassium levels. In order for the North American farmer to maximize yields, application of higher rates of potash will be necessary in the future.

Our production volume of potash of 222,000 tons in the first quarter of 2013 was relatively consistent with the 218,000 tons produced in the first quarter of 2012. Our East facility had strong production in the first quarter of 2013, with a 56% increase in potash production in the first quarter of 2013, compared to the same period in 2012. This production gain was offset by the impact of cold weather at our Utah facilities which reduced plant availability and recoveries. Our cash operating costs of goods sold were $174 per ton for the first quarter of 2013, compared to $195 per ton in the first quarter of 2012. The decrease in our cash operating cost of goods sold per ton is mainly due to our continued operating improvement at our East facility during 2012, which continued into the first quarter of 2013 as higher production volumes generally reduce our per ton costs.

22

Trio^® 

Our Trio^® production and inventory levels were relatively higher in 2013 than they were in 2012. Our sales of Trio^® increased from 28,000 tons of Trio^® in the first quarter of 2012 to 39,000 tons of Trio^® in the first quarter of 2013. Pricing and demand for this specialty product remain strong. With continuing strong demand for this specialty product, we expect sales demand will at least meet our production capabilities in 2013. For the first quarter of 2013, as compared to the first quarter of 2012, our average Trio^® gross margin per ton increased by $94 per ton as our average net realized sales price for Trio^® increased by $49 per ton and our cash cost of goods sold for Trio^® decreased by $41 per ton. The decrease in our cash cost of goods sold was due to the benefit of producing at higher rates.

Although we have seen improvement in our Trio^® recoveries as a result of our long term improvement work at our East facility, the expected production benefits from the Langbeinite Recovery Improvement Project ("LRIP") have yet to be fully realized and we are continuing to work towards the initial design capacity levels for Trio^® and effectively utilizing the pelletization circuit to produce increased quantities of our premium-sized Trio^® product. We remain committed to continuing the long-term improvement plan and commissioning work on LRIP to obtain increased recoveries and therefore increased production levels of langbeinite.

Our export sales of Trio^® tend to be in larger quantities and the timing of those sales has an impact on quarterly results.

Average Net Realized Sales Price

Domestic pricing of our potash is influenced principally by the price established by our competitors. The interaction of global potash supply and demand, ocean, land and barge freight rates, and currency fluctuations also influence pricing. Any of these factors could have a positive or negative impact on the price of our products. Our average net realized sales price for potash decreased in the first quarter of 2013 by $17 per ton from the fourth quarter of 2012, largely in response to the ongoing uncertainty surrounding production and consumption in the global potash market. We continue to believe potash buying and pricing will trade in a relatively narrow range due to strong corn and soybean commodity prices that support favorable farmer economics. We expect our average net realized sales price in the second quarter of 2013 to be slightly lower than the level experienced in the first quarter of 2013 as the impact of the lower spring pricing levels established by the Canadian potash producers is fully reflected in the market.

We market Trio^® as a specialty product. As farmers have increasingly recognized the agronomic value of the magnesium and sulfate delivered by this product, demand for the product has grown and we have enjoyed a higher market price through 2012 and into 2013. This recognition has resulted in pricing that more closely reflects the agronomic value of the delivered nutrients.

The table below demonstrates the progression of our average net realized sales price for potash and Trio^® through 2012 and into 2013.

Average net realized sales price for the three months ended:	Potash	Trio®

Specific Factors Affecting Our Results

23

Sales

Our gross sales are derived from the sales of potash and Trio^® and are determined by the quantities of product we sell and the sales prices we realize. We quote prices to customers both on a delivered basis and on the basis of pick-up at our plants and warehouses. Freight costs are incurred on only a portion of our sales as many of our customers arrange and pay for their own freight directly. When we arrange and pay for freight, our quotes and billings are based on expected freight costs to the points of delivery. Our gross sales include the freight that we bill, but we do not believe that gross sales provide a representative measure of our performance in the market due to variations caused by ongoing changes in the proportion of customers paying for their own freight, the geographic distribution of our products, and freight rates. We view net sales, which are gross sales less freight costs, as the key performance indicator of our revenue as it conveys the net sales price of the product that we realize. We manage our sales and marketing operations centrally and we work to achieve the highest average net realized sales price we can by evaluating the product needs of our customers and associated logistics and then determining which of our production facilities can best satisfy these needs.

The volume of product we sell is determined by demand for our products and by our production capabilities. We intend to operate our facilities at full production levels, which provide the greatest operating efficiencies. By having adequate warehouse capacity, we can maintain production levels during periods of fluctuating product demand.

Cost of Goods Sold

Our cost of goods sold reflects the costs to produce our potash and Trio^® products, less credits generated from the sale of our by-products. Many of our production costs are largely fixed and, consequently, our costs of sales per ton on a facility-by-facility basis tend to move inversely with the number of tons we produce, within the context of normal production levels. Our principal production costs include labor and employee benefits, maintenance materials, contract labor, and materials for operating or maintenance projects, natural gas, electricity, operating supplies, chemicals, depreciation and depletion, royalties, and leasing costs. There are elements of our cost structure associated with contract labor, consumable operating supplies, and reagents and royalties that are variable, which make up a smaller component of our cost base. Our periodic production costs and costs of goods sold will not necessarily match one another from period-to-period based on the fluctuation of inventory and production levels.

Our production costs per ton are also impacted when our production levels change, due to factors such as changes in mine development, downtime, and annual maintenance turnarounds. Our labor and contract labor costs in Carlsbad, New Mexico, may continue to be influenced most directly by the demand for labor in the local Carlsbad, New Mexico, region where we compete for labor with the potash, oil and gas, and nuclear waste storage industries. Additionally, the East mine has a complex mineralogy with a mixed ore body comprised of potash and langbeinite that is processed through a singular product flow at the surface facility. This complex mineralogy will influence the amount of product tons of potash and Trio^® ultimately produced from the facility, which impacts our production costs per ton for each product and affects our quarter-to-quarter results.

We pay royalties to federal, state, and private lessors under our mineral leases, and these payments are typically a percentage of net sales of minerals extracted and sold under the applicable lease. In some cases, federal royalties for potash are paid on a sliding scale basis that varies with the grade of ore extracted. For the first quarter of 2013 and 2012, our average royalty rate was 4.1% and 3.8%, respectively. We expect that future average royalty rates will increase as certain New Mexico mineral leases are currently being renewed at a fixed royalty rate of 5.0%.

Income Taxes

We are a subchapter C corporation and, therefore, are subject to federal and state income taxes on our taxable income. For the three months ending March 31, 2013, and 2012, our effective income tax rate was 36.8% and 37.9%, respectively. Our effective income tax rates are impacted primarily by changes in the underlying tax rates in jurisdictions in which we are subject to income tax and permanent differences between book and tax income for the period, including the benefit associated with the estimated effect of the depletion and domestic production activities deduction. Our federal and state income tax returns are subject to examination by federal and state tax authorities.

For the three months ended March 31, 2013, the total tax expense was $8.7 million. Total tax expense for the three months ended March 31, 2013, was comprised of $0.3 million of current income tax expense and $8.4 million of deferred income tax expense. For the three months ended March 31, 2012, the total tax expense was $12.6 million. Total tax expense for the three months ended March 31, 2012, was comprised of $2.6 million of current income tax expense and $10.0 million of deferred income tax expense. Our current tax expense for each of these periods was less than our total tax expense in large part due to the impacts of accelerated tax bonus depreciation and the utilization of percentage depletion.

24

We evaluate our deferred tax assets and liabilities each reporting period using the enacted tax rates expected to apply to taxable income in the periods in which the deferred tax liability or asset is expected to be settled or realized. The estimated statutory income tax rates that are applied to our current and deferred income tax calculations are impacted most significantly by the states in which we do business. Changing business conditions for normal business transactions and operations, as well as changes to state tax rate and apportionment laws, potentially alter our apportionment of income among the states for income tax purposes. These changes in apportionment laws result in changes in the calculation of our current and deferred income taxes, including the valuation of our deferred tax assets and liabilities. The effects of any such changes are recorded in the period of the adjustment. These adjustments can increase or decrease the net deferred tax asset on the balance sheet and impact the corresponding deferred tax benefit or deferred tax expense on the income statement.

In April 2013, the state of New Mexico lowered its corporate income tax rate from 7.6% currently to 5.9% on a graduated basis through 2018. Accordingly, the estimated state tax rate that we apply to our deferred tax asset will also decrease, which will result in an increase in our deferred state tax provision. We currently estimate that this increased deferred state tax provision expense will be between $1.0 million and $1.4 million and will be recorded in the second quarter of 2013. Because this state tax rate comprises a significant portion of our state income tax rate and the fact that the rate reduction is phased-in over several years, we will periodically update our assumptions around the timing of our deferred tax asset, and we will record adjustments to our deferred state income tax expense accordingly.

Capital Investment

We believe that, in the long term, demand for potash will remain at, or exceed, historical levels. We have developed a capital investment plan at each of our facilities to respond to this anticipated increase in demand. These plans focus on growing productivity and improving recoveries while improving safe and reliable production, ensuring environmental and regulatory compliance, and improving facility reliability. We expect these investments to grow production capacity and decrease per ton production costs while also increasing the flexibility of our production mix to support our marketing efforts. We have already made significant steps towards improving our granulation capacity for both potash and Trio^® through previous capital investments and we are continuing to increase our granulation capacity for potash.

As we invest in our facilities, we seek to deploy capital while maintaining sufficient liquidity to react strategically to market conditions. In the first quarter of 2013, we invested $64.2 million in capital projects. The total capital investment in 2013 is estimated to be between $235 and $285 million. This investment consists of our three largest projects including the expected completion of the construction for the HB Solar Solution mine and the related production plant, the expansion of our North compaction facility and the drilling program to create the third multi-lateral cavern system in Moab. The actual level of capital investment for the year will ultimately be impacted by the timing of deliveries of equipment and the construction schedule. We expect our 2013 operating plans and capital programs to be funded out of operating cash flows, existing cash and investments, and a portion of the net proceeds from the $150 million unsecured senior notes (the "Notes") received in April 2013. We expect that our capital investment will begin to decrease at some point during the fourth quarter of 2013 to a level below our cash flow from operations.

The following details several of the significant projects that are designed to improve the overall reliability of the operations and to increase productive and compaction capacity:

• We are making significant progress on the HB Solar Solution mine, as discussed previously. The total expected investment for the project is between $225 million and $245 million, of which $151.2 million had been invested as of March 31, 2013. We currently expect first production of finished product from the HB Solar Solution mine to occur late in the fourth quarter of 2013 following completion of the production plant. We expect to see a ramp up of production in 2014, with production levels increasing into 2015, assuming the benefit of an average annual evaporation cycle applied to full evaporation ponds. The anticipated production schedule may be impacted by any construction delays, the timing of critical equipment deliveries and the impact of weather events or patterns on evaporation seasons.

• The North compaction project is expected to be completed in phases to coincide with the production increases from the HB Solar Solution mine and the expansion of mining and milling capacity at the West mine. The first two compactor lines are scheduled to be completed in phases in mid-2013, with the third compaction line completed in early 2014. This project will provide adequate capacity for the increased throughput expected at the West facility and the anticipated production from the HB Solar Solution mine. Total capital investment for the project is expected to be approximately $95 million to $100 million, of which approximately $72.6 million had been invested as of March 31, 2013.

25

• We are developing additional solution mining opportunities at our Moab facility. We completed the development of our second horizontal cavern systems in the fourth quarter of 2012 and are now actively engaged in developing a third horizontal cavern system. This represents a capital investment of approximately $20 million to $30 million, of which $4.9 million had been invested as of March 31, 2013. The addition of the new horizontal cavern systems is expected to provide higher extracted brine grades. In addition, we expect that the production from the new cavern systems will not only offset the typical decreasing production profile as other cavern systems are depleted, but allow for incremental production opportunities.

Liquidity and Capital Resources

As of March 31, 2013, we had cash, cash equivalents, and investments of $7.6 million, we had no debt, and we had $250.0 million available under our unsecured credit facility. In April 2013, we received the funding of our Notes with net proceeds of $149.3 million, as described in more detail below. The $7.6 million of cash, cash equivalents and investments at March 31 2013, was made up of:

• $4.1 million in cash;

• $1.0 million in cash equivalent investments, consisting of money market accounts with banking institutions that we believe are financially sound;

• $2.5 million invested in short-term investments, comprised of certificates of deposit investments.

Our operations have been and are expected to be primarily funded from cash on hand and cash generated by operations and, if necessary, we have the ability to borrow under our unsecured credit facility.

Operating Activities

Total cash provided by operating activities decreased by $26.0 million in the first quarter of 2013 compared with the first quarter of 2012. Inventory increased $13.0 million as we produced more than we sold during the first quarter of 2013, which decreased our operating cash flows. In addition, we experienced an increase of $6.0 million in accounts payable and accrued liabilities.

Investing Activities

Total cash used in investing activities decreased in the first quarter of 2013 compared to the first quarter of 2012 due to a decrease in the purchases of short-term investments. We continue to fund our increased activity associated with investments in property, plant, and equipment, mineral properties and development costs from our operations with $61.1 million invested in the first quarter of 2013 compared with $38.5 million in the first quarter of 2012.

Financing Activities

We did not have any significant financing activities in the first quarter of 2013 or 2012.

Unsecured Credit Facility

We have an unsecured credit facility, led by U.S. Bank, as administrative agent, and Wells Fargo Bank, as syndication agent. This unsecured credit facility provides a total facility of $250 million. The facility is guaranteed by our material subsidiaries and includes financial covenants requiring a minimum fixed charge coverage ratio and a maximum leverage ratio. The facility has a five-year term through August 2016. The entire amount of the facility was available for use as of March 31, 2013.

Outstanding balances under the unsecured credit facility bear interest at a floating rate, which, at our option, is either (1) the London Interbank Offered Rate (LIBOR), plus a margin of between 1.25% and 2.0%, depending upon our leverage

26

ratio, which is equal to the ratio of our total funded indebtedness to our adjusted earnings for the prior four fiscal quarters before interest, income taxes, depreciation, amortization and certain other expenses; or (2) an alternative base rate, plus a margin of between 0.25% and 1.0%, depending upon our leverage ratio. We pay a quarterly commitment fee on the outstanding portion of the unused revolving unsecured credit facility amount of between 0.20% and 0.35%, depending on our leverage ratio. The interest rate paid under our unsecured credit facility on any debt varies both with the change in the LIBOR rates and with our leverage ratio.

Unsecured Senior Notes

In April 2013, we issued $150 million aggregate principal amount of the Notes pursuant to a note purchase agreement entered into in August 2012. We received proceeds of $149.3 million, net of offering expenses. The Notes consist of the following series:

• $60 million of 3.23% Senior Notes, Series A, due April 16, 2020

• $45 million of 4.13% Senior Notes, Series B, due April 14, 2023

• $45 million of 4.28% Senior Notes, Series C, due April 16, 2025

The Notes are senior unsecured obligations and rank equally in right of payment with any of our other unsubordinated unsecured indebtedness. The obligations under the Notes are unconditionally guaranteed by our material subsidiaries. The note purchase agreement includes financial covenants requiring a minimum fixed charge ratio and a maximum leverage ratio. Interest on the Notes accrues from April 16, 2013, and will be paid semiannually on April 16 and October 16 of each year, beginning on October 16, 2013.

Contractual Obligations

As of March 31, 2013, we had contractual obligations totaling $98.4 million on an undiscounted basis, as indicated below. Contractual commitments shown are for the full calendar year indicated unless otherwise indicated.

(1) Includes all operating lease payments, inclusive of sales tax, for leases for office space, an airplane, railcars and other equipment.

(2) Purchase contractual commitments include the approximate amount due vendors for non-cancelable purchase commitments for materials and services.

(3) We have committed to purchase a minimum quantity of natural gas, which is priced at floating index‑dependent rates plus $0.02 to $0.13, estimated based on forward rates. Amounts are based on spot rates inclusive of estimated transportation costs and sales tax.

(4) We terminated our obligations under the Pension Plan, and our remaining liability was funded in April 2013. In the second quarter of 2013, we will recognize additional expense of approximately $1.9 million on termination of the Pension Plan in an amount equal to the difference between the final amount funded and the sum of the recorded pension liability and the unrecognized actuarial loss included in accumulated other comprehensive income.

(5) We are obligated to reclaim and remediate lands that our operations have disturbed, but, because of the long-term nature of our reserves and facilities, we estimate that the majority of those expenditures will not be required until after 2017. Although our reclamation obligation activities are not required to begin until after we cease operations, we anticipate certain activities to occur prior to then related to reclamation of facilities that have been replaced with

27

newly constructed assets, as well as certain shaft closure activities for shafts that are no longer in use. Commitments shown are in today’s dollars and are undiscounted.

(6) Estimated annual minimum royalties due under mineral leases, assuming approximately a 25-year life, consistent with estimated useful lives of plant assets.

Off-Balance Sheet Arrangements

As of March 31, 2013, we had no off-balance sheet arrangements aside from the operating leases described above under “Contractual Obligations” and bonding obligations described in the Notes to the Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

Results of Operations for the Three Months Ended March 31, 2013, and 2012

Net Sales

Net sales of potash decreased $19.7 million, or 20%, from $97.0 million for the three months ended March 31, 2012, to $77.3 million for the three months ended March 31, 2013. This decrease was primarily the result of a decrease in the average net realized sales price of potash by $60 per ton, or 13%, in addition to a 9% decrease in sales volumes of potash in the comparable period. During the first quarter of 2013, our sales were impacted by the timing of the spring application season as discussed above. Comparatively, the spring application season began slightly earlier in the first quarter of 2012, which allowed for an earlier spring planting season.

Net sales of Trio^® increased from $8.5 million for the three months ended March 31, 2012, to $13.8 million for the three months ended March 31, 2013, due to a 39% increase in the volume of sales in addition to a 16% increase in the average net realized sales price. We continue to see strong demand for all sizes of our Trio^® product. Trio^® domestic pricing has historically tended to move in a relatively close relationship to potash, although, over the last year, dealers' and farmers' recognition of the added value of magnesium and sulfate from this specialty product has translated into higher prices despite sequentially lower potash prices during the same period.

Our production volume of potash in the first quarter of 2013 was 222,000 tons, or 4,000 tons more than in the first quarter of 2012, primarily due to the results of our long-term improvement plan at our East facility, offset by lower production at our Utah facilities due to cold weather in January 2013. Furthermore, our Trio^® production increased 16,000 tons or 53% in the first quarter of 2013 as we continue to progress with operating our East facility more effectively and efficiently.

Cost of Goods Sold

The following table presents our cost of goods sold for potash and Trio^® for the subject periods:

	Three Months Ended March 31,				Change Between
	2013		2012		Periods			% Change
Cost of goods sold (in millions)	$	53.8	$	60.6	$	(6.8	)	(11	)%
Cost per ton of potash sold(1)	$	236	$	256	$	(20	)	(8	)%
Cost per ton of Trio® sold(2)	$	252	$	297	$	(45	)	(15	)%

(1) Depreciation and depletion expense for potash was $8.5 million and $9.0 million in the first quarter of 2013 and 2012, respectively, which equates to $46 and $44 on a per ton basis.

(2) Depreciation and depletion expense for Trio^® was $2.1 million and $1.7 million in the first quarter of 2013 and 2012, respectively, which equates to $54 and $61 on a per ton basis.

Total cost of goods sold of potash, which includes royalties and depreciation, depletion and amortization, decreased $20 per ton, or 8%, from $256 per ton for the three months ended March 31, 2012, to $236 per ton for the three months ended March 31, 2013. We experienced higher cash operating cost of goods sold per ton for the first quarter of 2012, as operating time and plant availability at our East mine was negatively impacted by the production challenges that we had at this facility. Our long-term improvement plan at our East facility has resulted in less down time. As a result, our per ton carrying value of inventory at the East facility in 2013 was lower than we experienced in 2012.

28

Total cost of goods sold of Trio^® decreased $45 per ton, or 15%, from $297 per ton for the three months ended March 31, 2012, to $252 per ton for the three months ended March 31, 2013. This decrease in cost of goods sold on a per ton basis largely resulted from the higher production volumes in the first quarter of 2013 over which production costs are allocated. As a result, our per ton production costs decreased in the first quarter of 2013 over those in the first quarter of 2012.

In total, our cost of goods sold decreased $6.8 million, or 11%, from $60.6 million in the three months ended March 31, 2012, to $53.8 million in the three months ended March 31, 2013. This decrease is primarily due to a decrease in the number of tons sold. Our solid production results decreased our per ton production costs, despite increases in labor costs, electricity and operating supplies.

On a comparative basis and within our production costs, depreciation and depletion increased $2.7 million, or 26%, during the first quarter of 2013 as a result of the significant capital investments being brought on line over the last two years. We expect depreciation expense to continue to increase on both an actual dollar basis and on a per ton basis as we continue to invest capital into our operations. We manage capital investments on a basis of evaluating capital projects that we believe are necessary to maintain the productivity of our mines, as well as investment capital that is designed to increase production and generate incremental returns on invested capital.    

Selling and Administrative Expense

Selling and administrative expenses increased $1.2 million in the first quarter of 2013, as compared to the first quarter of 2012. The change represents a 14% increase from $8.3 million for the three months ended March 31, 2012, to $9.5 million for the three months ended March 31, 2013. This increase was primarily due to higher labor and benefit costs in the first quarter of 2013 as a result of additional headcount as we hired additional professional staff to support our level of process improvements and general administrative support.

Critical Accounting Policies and Estimates

Our Annual Report on Form 10-K for the year ended December 31, 2012,describes the critical accounting policies that affect our more significant judgments and estimates used in the preparation of our consolidated financial statements. There have been no significant changes to our critical accounting policies since December 31, 2012.

Recent Accounting Pronouncements

In February 2013, FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting these reclassifications. This ASU expands the presentation of changes in accumulated other comprehensive income. The new guidance requires an entity to disaggregate the total change of each component of other comprehensive income either on the face of the net income statement or as a separate disclosure in the notes. ASU 2013-02 is effective for fiscal years beginning after December 15, 2012. The adoption of this ASU did not have a significant impact on our consolidated financial position, results of operations or cash flows.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Part II, Item 7A., "Quantitative and Qualitative Disclosure About Market Risk," of our Annual Report on Form 10-K for the year ended December 31, 2012, describes our exposure to market risk. There have been no significant changes to our market risk exposure since December 31, 2012.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act. Our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms. Our disclosure controls and procedures are also designed to ensure that this information is accumulated and communicated to our management, including our Executive Chairman of the Board and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Based on their evaluation as of March 31, 2013, our Executive Chairman of the Board and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

29

Changes in Internal Control over Financial Reporting

Our management, including our Executive Chairman of the Board and Chief Financial Officer, conducted an evaluation of our “internal control over financial reporting,” as defined in Rule 13a-15(f) of the Exchange Act to determine whether any changes in our internal control over financial reporting occurred during the three months ended March 31, 2013, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Based on that evaluation, there have been no changes in our internal control over financial reporting that occurred during the three months ended March 31, 2013, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our Executive Chairman of the Board and Chief Financial Officer, do not expect that our disclosure controls or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Intrepid have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II-OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Protests of Applications for Permits to Drill (“APDs”)

From time to time, and depending on location and potential impact, Intrepid protests APDs in the Designated Potash Area, in southeastern New Mexico, submitted by various oil and gas operators. These protests are submitted to the applicable state or federal agency. Certain of these APDs may be located on or directly impact our state or federal potash leases or pending lease applications. There can be no assurance that our protests will result in the denial of the APDs and, if these APDs are granted and we are not successful in any appeal thereof, wells drilled under these APDs could potentially interfere with our ability to mine potash deposits under lease to Intrepid or that Intrepid seeks to lease.

Other Matters

We are subject to claims and legal actions in the ordinary course of business. While there are uncertainties in predicting the outcome of any claim or legal action, we believe that the ultimate resolution of these claims or actions is not reasonably likely to have a material adverse effect on our consolidated financial position or the results of operations. We maintain liability insurance that will apply to some claims and actions and believe that our coverage is reasonable in view of the insurable legal risks to which our business ordinarily is subject.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risks discussed in Part I, "Item 1A: Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2012, which could materially affect our business, financial condition or future results. These risks include all of the material risks known to us; however additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, or future results. There have been no material changes in the risk factors contained in our Annual Report on Form 10-K for the year ended December 31, 2012.

ITEM 4. MINE SAFETY DISCLOSURES

We are committed to providing a safe and healthy work environment. The objectives of our safety programs are to eliminate workplace accidents and incidents, to preserve employee health, and to comply with safety- and health-based regulations. We seek to achieve these objectives by training employees in safe work practices; establishing, following, and improving safety standards; involving employees in safety processes; openly communicating with employees about safety matters; and recording, reporting, and investigating accidents, incidents, and losses to avoid recurrence. As part of our ongoing safety programs, we collaborate with regulators to identify and implement promising new accident prevention techniques and practices.

Our mining operations are subject to regulation by the Mine Safety and Health Administration ("MSHA"), the Occupational Health and Safety Administration, and related state regulatory bodies. Exhibit 95.1 to this Quarterly Report on Form 10-Q provides the information concerning MSHA mine safety violations and other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K.

Below are additional details about the information provided in the table above.

• General - In general, the number of citations and orders will vary depending on the size of the mine, the individual inspector assigned to the mine, and the specific mine characteristics. Citations and orders can be contested and appealed and, in that process, are often reduced in severity and amount and are sometimes vacated.

• MSHA Identification Numbers - MSHA assigns an identification number to each mine and may or may not assign separate identification numbers to related facilities. We provide the information in the table by MSHA identification number.

• Section 104 Significant and Substantial (“S&S”) Citations - These citations are issued for alleged violations of a mining safety standard or regulation where there exists a reasonable likelihood that the hazard contributed to or will result in an injury or illness of a reasonably serious nature.

Company Background Disclosure [Abstract]

COMPANY BACKGROUND

COMPANY BACKGROUND

Intrepid Potash, Inc. (individually or in any combination with its subsidiaries, “Intrepid”) produces muriate of potash (“potassium chloride” or “potash”) and langbeinite. Langbeinite, which is marketed for sale as Trio^®, is a low-chloride potassium fertilizer with the additional benefits of sulfate and magnesium. Intrepid sells potash and Trio^® primarily into the agricultural market as a fertilizer. Intrepid also sells these products into the animal feed market as a nutritional supplement and sells potash into the industrial market as a component in drilling and fracturing fluids for oil and gas wells. In addition, Intrepid sells by-products including salt, magnesium chloride and metal recovery salts.

Intrepid owns five active potash production facilities: three in New Mexico, and two in Utah. Intrepid is constructing a sixth production facility, the HB Solar Solution mine, near Carlsbad, New Mexico. Intrepid has placed into service certain assets of the HB Solar Solution mine project, as it is already injecting brine into the production caverns and pumping potassium-rich brine into several of the newly constructed solar evaporation ponds.

Currently, production comes from two underground mines in the Carlsbad region of New Mexico; a solar evaporation solution mine near Moab, Utah; and a solar evaporation shallow brine mine in Wendover, Utah. Trio^® production comes from mining the mixed ore body that contains both potash and langbeinite, which is mined and processed at the East facility near Carlsbad, New Mexico. Intrepid manages sales and marketing operations centrally. This allows Intrepid to evaluate the product needs of its customers and then determine which of its production facilities to use to fill customers’ orders in a manner designed to realize the highest average net realized sales price to Intrepid. Intrepid calculates average net realized sales price by deducting freight costs from gross revenues and then by dividing this result by tons of product sold during the period. Intrepid also monitors product inventory levels and overall production costs centrally. Intrepid has one reporting segment being the extraction, production, and sale of potassium related products. Intrepid's extraction and production operations are conducted entirely in the continental United States.

EMPLOYEE BENEFITS

Defined Benefit Pension Plan—In accordance with the terms of the Moab Purchase Agreement associated with the purchase of the assets relating to its Moab facility in 2000, Intrepid and its predecessor established the Moab Salt, L.L.C. Employees’ Pension Plan (“Pension Plan”), a defined benefit pension plan. Pursuant to the terms of the Moab Purchase Agreement, employees transferring from the acquiree to Intrepid were granted credit under the Pension Plan for their prior service and for the benefits they had accrued under the acquiree’s pension plan, and approximately $1.5 million was transferred from the acquiree’s pension plan to the Pension Plan to accommodate the recognition of these prior services and benefits. In February 2002, Intrepid froze the benefits to be paid under the Pension Plan by limiting participation in the Pension Plan solely to employees hired before February 22, 2002, and by including only pay and service through February 22, 2002, in the calculation of benefits.

In December 2011, Intrepid adopted resolutions to terminate the Pension Plan. Prior to Intrepid's Pension Plan liability being fully funded, certain regulatory approvals, plan amendments and participant settlement elections needed to be obtained. In April 2013, Intrepid funded $2.0 million to settle all Pension Plan liabilities. Intrepid will record an additional expense of approximately $1.9 million to reflect the termination of the Pension Plan in the second quarter of 2013. This amount will be recorded as "Other expense" in the condensed consolidated statement of operations and represents the difference between the final amount funded, the recorded pension liability and the unrecognized actuarial loss included in accumulated other comprehensive income.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

3 Months Ended

Mar. 31, 2013

Accounting Policies [Abstract]

Principles of Consolidation

The consolidated financial statements of Intrepid include the accounts of Intrepid and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Intrepid bases its 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.

Significant estimates include 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 derivative financial instruments, 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 Intrepid’s mineral properties, the useful lives of related property, plant, and equipment, estimates associated with asset retirement obligations, and depreciation expenses.

Revenue Recognition

Revenue is recognized when evidence of an arrangement exists, risks and rewards of ownership have been transferred to customers, which is generally when title passes, the selling price is fixed and determinable, and collection is reasonably assured. Title passes at the designated shipping point for the majority of sales, but, in a few cases, title passes at the delivery destination. The shipping point may be the plant, a distribution warehouse, a customer warehouse, or a port. Title passes for some international shipments upon payment by the purchaser; however, revenue is not recognized for these transactions until shipment because the risks and rewards of ownership have transferred pursuant to a contractual arrangement. Prices are generally set at the time of, or prior to, shipment. In cases where the final price is determined upon resale of the product by the customer, revenue is deferred until the final sales price is known.

Sales are reported on a gross basis. Intrepid quotes prices to customers both on a delivered basis and on the basis of pick-up at Intrepid’s plants and warehouses. When a sale occurs on a delivered basis, Intrepid incurs and, in turn, bills the customer and records as gross revenue the product sales value, freight, packaging, and certain other distribution costs. Many customers, however, arrange and pay for these costs directly and, in these situations, only the product sales are included in gross revenues.

By-product Credits

When by-product inventories are sold, Intrepid records the sale of by-products as a credit to cost of goods sold.

Inventory and Long-Term Parts Inventory

Inventory consists of product and by-product stocks that are ready for sale; mined ore; potash in evaporation ponds, which is considered work-in-process; and parts and supplies inventory. Product and by-product inventory cost is determined using the lower of weighted average cost or estimated net realizable value and includes direct costs, maintenance, operational overhead, depreciation, depletion, and equipment lease costs applicable to the production process. Direct costs, maintenance, and operational overhead include labor and associated benefits.

Intrepid evaluates its production levels and costs to determine if any should be deemed abnormal and therefore excluded from inventory costs and expensed directly during the applicable period. The assessment of normal production levels is judgmental and is unique to each period. Intrepid models normal production levels and evaluates historical ranges of production by operating plant in assessing what is deemed to be normal.

Parts inventory, including critical spares, that is not expected to be utilized within a period of one year is classified as non-current. Parts and supply inventory cost is determined using the lower of average acquisition cost or estimated replacement cost. Detailed reviews are performed related to the net realizable value of parts inventory, giving consideration to quality, slow-moving items, obsolescence, excessive levels, and other factors. Parts inventories not having turned-over in more than a year, excluding parts classified as critical spares, are reviewed for obsolescence and, if deemed appropriate, are included in the determination of an allowance for obsolescence.

Property, Plant, and Equipment

Property, plant, and equipment are stated at historical cost. Expenditures for property, plant, and equipment relating to new assets or improvements are capitalized, provided the expenditure extends the useful life of an asset or extends the asset’s functionality. Property, plant, and equipment are depreciated under the straight-line method using estimated useful lives. No depreciation is taken on assets classified as construction in progress until the asset is placed into service. Gains and losses are recorded upon retirement, sale, or disposal of assets. Maintenance and repair costs are recognized as period costs when incurred. Capitalized interest, to the extent of debt outstanding, is calculated and assigned to assets that are being constructed, drilled, or built or that are otherwise classified as construction in progress.

Recoverability of Long-Lived Assets

Intrepid evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amount may not be recoverable. An impairment is considered to exist if an asset’s total estimated net future cash flows on an undiscounted basis are less than the carrying amount of the related asset. An impairment loss is measured and recorded based on the discounted estimated future cash flows. Changes in significant assumptions underlying future cash flow estimates or fair values of assets may have a material effect on our financial position and results of operations.

Mineral Properties and Development Costs

Mineral properties and development costs, which are referred to collectively as mineral properties, include acquisition costs, the cost of drilling wells, and the cost of other development work, all of which are capitalized. Depletion of mineral properties is calculated using the units-of-production method over the estimated life of the relevant ore body. The lives of reserves used for accounting purposes are shorter than current reserve life determinations due to uncertainties inherent in long-term estimates. These reserve life estimates have been prepared by us and reviewed and independently determined by mine consultants. Tons of potash and langbeinite in the proven and probable reserves are expressed in terms of expected finished tons of product to be realized, net of estimated losses. Market price fluctuations of potash or Trio^®, as well as increased production costs or reduced recovery rates, could render proven and probable reserves containing relatively lower grades of mineralization uneconomic to exploit and might result in a reduction of reserves. In addition, the provisions of Intrepid’s mineral leases, including royalty provisions, are subject to periodic readjustment by the state and federal government, which could affect the economics of its reserve estimates. Significant changes in the estimated reserves could have a material impact on Intrepid’s results of operations and financial position.

Exploration Costs

Exploration costs include geological and geophysical work performed on areas that do not yet have proven and probable reserves declared. These costs are expensed as incurred.

Asset Retirement Obligation

Reclamation costs are initially recorded as a liability associated with the asset to be reclaimed or abandoned, based on applicable inflation assumptions and discount rates. The accretion of this discounted liability is recognized as expense over the life of the related assets, and the liability is periodically adjusted to reflect changes in the estimates of either the timing or amount of the reclamation and abandonment costs.

Planned Turnaround Maintenance

Each production operation typically shuts down periodically for planned maintenance activities. The costs of maintenance turnarounds at Intrepid's facilities are considered part of production costs and are absorbed into inventory in the period incurred.

Leases

Upon entering into leases, Intrepid evaluates whether leases are operating or capital leases. Operating lease expense is recognized as incurred. If lease payments change over the contractual term or involve contingent amounts, the total estimated cost over the term is recognized on a straight-line basis.

Income Taxes

Intrepid is a subchapter C corporation and therefore is subject to U.S. federal and state income taxes. Intrepid recognizes income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the periods in which the deferred tax liability or asset is expected to be settled or realized. Intrepid records a valuation allowance if it is deemed more likely than not that its deferred income tax assets will not be realized in full. These determinations are subject to ongoing assessment.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and liquid investments with an original maturity of three months or less.

Investments

Intrepid’s short-term and long-term investments consist of certificates of deposit with various banking institutions, municipal tax-exempt and corporate taxable bonds, and corporate convertible debentures, which have been classified as either held-to-maturity or available-for-sale securities. Short-term investments on the consolidated balance sheets have remaining maturities to Intrepid less than or equal to one year and investments classified as long-term on the consolidated balance sheets have remaining maturities to Intrepid greater than one year. With regard to the financial instruments classified as held-to-maturity investments, they are carried on the consolidated balance sheets at cost, net of amortized premiums or discounts paid. The available-for-sale securities are carried at fair value, with changes in fair value recognized through "Other Comprehensive Loss" on the condensed consolidated balance sheets. Fair value is assessed using a market‑based approach.

Fair Value of Financial Instruments

Intrepid’s financial instruments include cash and cash equivalents, certificate of deposit investments, short-term and long-term investments, restricted cash, accounts receivable, income tax receivables, and accounts payable, all of which are carried at cost, except for available-for-sale investments which are carried at fair value. The remaining investments approximate fair value due to the short-term nature of these instruments. Allowances for doubtful accounts are recorded against the accounts receivable balance to estimate net realizable value. Although there are no amounts currently outstanding under Intrepid’s unsecured credit facility, any borrowings that become outstanding are expected to be recorded at amounts that approximate their fair value as borrowings bear interest at a floating rate.

In April 2013, Intrepid issued $150 million aggregate principal amount of unsecured senior notes ("the Notes"). The Notes bear interest at fixed rates and are deemed to be financial instruments. Accordingly, the fair value of the Notes will be determined on a periodic basis and disclosed. Since considerable judgment is required to develop estimates of fair value, the estimates provided are not necessarily indicative of the precise amounts that could be realized upon the sale, settlement, or refinancing of the instruments.

Earnings per Share

Basic net income per common share of stock is calculated by dividing net income available to common stockholders by the weighted average basic common shares outstanding for the respective period.

Diluted net income per common share of stock is calculated by dividing net income by the weighted average diluted common shares outstanding, which includes the effect of potentially dilutive securities. Potentially dilutive securities for the diluted earnings per share calculation consist of awards of non-vested restricted shares of common stock, non-vested performance units, and non-qualified stock options. The dilutive effect of stock based compensation arrangements are computed using the treasury stock method. Following the lapse of the vesting period of restricted shares of common stock, the shares are considered issued and therefore are included in the number of issued and outstanding shares for purposes of these calculations.

Stock-Based Compensation

Intrepid accounts for stock-based compensation by recording expense using the fair value of the awards at the time of grant. Intrepid has recorded compensation expense associated with the issuance of non-vested restricted shares of common stock, non-vested performance units, and non-qualified stock options, all of which are subject to service conditions. The expense associated with such awards is recognized over the service period associated with each issuance. Performance units are also subject to operational performance- or market-based conditions.

COMPENSATION PLANS

COMPENSATION PLANS

Cash Bonus Plan—Intrepid has cash bonus plans that allow participants to receive varying percentages of their aggregate base salary. Any awards under the cash bonus plans are based on a variety of elements related to Intrepid’s performance in certain production, operational, financial, and other areas, as well as the participants’ individual performance. Intrepid accrues cash bonus expense related to the current year’s performance.

Equity Incentive Compensation Plan—Intrepid's Board of Directors and stockholders have adopted a long-term incentive compensation plan called the Intrepid Potash, Inc. Equity Incentive Plan, as Amended and Restated (the "Plan"). Intrepid has issued common stock, restricted shares of common stock, performance units, and non-qualified stock option awards under the Plan. As of March 31, 2013, there were a total of 379,621 shares of non-vested restricted shares of common stock, 97,367 non-vested performance units representing shares of common stock, and options to purchase 344,563 shares of common stock. As of March 31, 2013, there were approximately 3.6 million shares of common stock that remain available for issuance under the Plan.

Common Stock

On an annual basis, under the Plan, the Compensation Committee of the Board of Directors (the "Compensation Committee") approves the award of shares of common stock to the non-employee members of the Board of Directors as compensation for service for the period ending on the date of Intrepid’s annual stockholders’ meeting for the following year. These shares of common stock were granted without restrictions and vested immediately.

Non-vested Restricted Shares of Common Stock

Under the Plan, grants of non-vested restricted shares of common stock have been awarded to executive officers, other key employees, and consultants. The awards contain service conditions associated with continued employment or service. There are no performance or market conditions associated with these awards. The terms of the non-vested restricted shares of common stock provide voting and regular dividend rights to the holders of the awards. Upon vesting, the restrictions on the restricted shares of common stock lapse, and the shares are considered issued and outstanding.

Since 2009, the Compensation Committee has granted restricted shares of common stock under the Plan in the first quarter of each year to Intrepid's executive management team and other selected employees as part of an annual equity award program. These awards vest ratably over three years. From time to time, the Compensation Committee grants restricted shares of common stock to newly hired or promoted employees or other employees or consultants who have achieved extraordinary personal performance objectives. These restricted shares of common stock generally vest over one- to four-year periods.

In measuring compensation expense associated with the grant of non-vested restricted shares of common stock, Intrepid uses the fair value of the award, determined as the closing stock price for Intrepid’s common stock on the grant date. Compensation expense is recorded monthly over the vesting period of the award. Total compensation expense related to the non-vested restricted shares of common stock awards for both the three months ended March 31, 2013, and 2012, was $0.8 million. These amounts are net of estimated forfeiture adjustments. As of March 31, 2013, there was $7.9 million of total remaining unrecognized compensation expense related to non-vested restricted shares of common stock that will be expensed through 2015.

A summary of activity relating to Intrepid’s non-vested restricted shares of common stock for the three months ended March 31, 2013, is presented below.

			Weighted Average Grant-Date Fair Value
	Shares
Non-vested restricted shares of common stock, beginning of period	240,757		$	26.04
Granted	232,336		$	19.26
Vested	(88,186	)	$	27.12
Forfeited	(5,286	)	$	21.60
Non-vested restricted shares of common stock, end of period	379,621		$	21.70

Performance Units

Since 2012, the Compensation Committee has granted performance units under the Plan to certain members of Intrepid's executive management team as part of the annual equity award program. The Compensation Committee issued two types of performance units: an operational performance-based award and a market condition-based award. The awards contain service conditions associated with continued employment, as well as an operational performance or market condition. The operational performance conditions are based on tons of potash and Trio^® produced, and the market conditions are based on Intrepid's stock performance relative to a peer group and a broad market index. As of March 31, 2013, the maximum number of shares of common stock that may be issued, pending satisfaction of the operational performance or market condition and continued employment is 97,367 shares of common stock. These performance shares are subject to vesting conditions that provided for issuance over a three-year period assuming continued employment by the individual grantees through the vesting dates. For the three months ended March 31, 2013, Intrepid recognized stock‑based compensation related to performance units of approximately $0.1 million. As of March 31, 2013, there was $1.2 million of total remaining unrecognized compensation expense related to unvested performance units that will be expensed through 2015.

Non-qualified Stock Options

From 2009 to 2011, the Compensation Committee issued non-qualified stock options under the Plan in the first quarter of each year to Intrepid’s executive management and other selected employees as part of its annual award program. These stock options generally vest ratably over three years. In measuring compensation expense for this grant of options, Intrepid estimated the fair value of the award on the grant date using the Black‑Scholes option valuation model. Option valuation models require the input of highly subjective assumptions, including the expected volatility of the price of the underlying stock.

For the three months ended March 31, 2013, and 2012, Intrepid recognized stock‑based compensation related to previously issued stock options of approximately $0.2 million and $0.4 million, respectively. As of March 31, 2013, there was $0.6 million of total remaining unrecognized compensation expense related to unvested non-qualified stock options that will be expensed through 2013 and 2014. Realized tax benefits from tax deductions for exercised options in excess of the deferred tax asset attributable to stock compensation for such options are regarded as “excess tax benefits.”

A summary of Intrepid’s stock option activity for the three months ended March 31, 2013, is as follows:

	Shares	Weighted Average Exercise Price	Aggregate Intrinsic Value (1)	Weighted Average Remaining Contractual Life	Weighted Average Grant-Date Fair Value
Outstanding non-qualified stock

INCOME TAXES

INCOME TAXES

Intrepid’s effective tax rate was 36.8% and 37.9% for the three months ended March 31, 2013, and 2012, respectively. Intrepid's effective tax rate is impacted primarily by the amount of taxable income associated with each jurisdiction in which Intrepid's income is subject to income tax, permanent differences between the financial statement carrying amounts and tax bases of assets, liabilities, and the benefit associated with the estimated domestic production activities deduction. A summary of the provision for income taxes is as follows (in thousands):

	Three Months Ended March 31,
	2013		2012
Current portion of income tax expense	317		2,622
Deferred portion of income tax expense	8,381		9,991
Total income tax expense	$	8,698	$	12,613

The blended state tax rate applied to the deferred tax calculation is subject to change due to changes in state laws and changes in the mix of Intrepid's business and the states in which Intrepid has a taxable relationship. This creates fluctuations in the value of Intrepid's net deferred tax asset. In April 2013, the state of New Mexico lowered its corporate income tax rate pursuant to a schedule that goes into effect over the next five years. Intrepid has estimated that the lower state income tax rates will result in a relatively lower future income tax expense. Further, Intrepid will record increased deferred state income tax expense in the three months ended June 30, 2013, as its deferred tax asset will have decreased in value. The estimated impact of this change on Intrepid's net deferred income tax value is currently estimated to be between $1.0 million and $1.4 million. The actual timing for the use of the deferred income tax asset will be based on the actual taxable income earned over future periods and will likely be different from the current estimate.

EARNINGS PER SHARE

The treasury stock method is used to measure the dilutive impact of non-vested restricted shares of common stock and outstanding stock options. For the three months ended March 31, 2013, and 2012, a weighted average of 40,314 and 76,705 non-vested shares of restricted common stock and 244,755 and 176,862 stock options, respectively, were anti-dilutive and therefore were not included in the diluted weighted average share calculation. For the three months ended March 31, 2012, 2,072 shares of common stock underlying non-vested performance units were anti-dilutive and therefore were not included in the diluted weighted average share calculation.

Recent Accounting Pronouncements

RECENT ACCOUNTING PRONOUNCEMENTS

In February 2013, FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting these reclassifications. This ASU expands the presentation of changes in accumulated other comprehensive income. The new guidance requires an entity to disaggregate the total change of each component of other comprehensive income either on the face of the net income statement or as a separate disclosure in the notes. ASU 2013-02 is effective for fiscal years beginning after December 15, 2012. The adoption of this ASU did not have a significant impact on its consolidated financial position, results of operations or cash flows.

Marketing Agreements—Intrepid has a marketing agreement appointing PCS Sales (USA), Inc. (“PCS Sales”) as its exclusive sales representative for potash export sales, with the exception of sales to Canada and Mexico, and appointing PCS Sales as its non-exclusive sales representative for potash sales into Mexico. Trio^® is also marketed under this arrangement. This agreement is cancelable with 30 days' written notice.

Intrepid has a sales agreement with an entity appointing such entity as the exclusive distributor, subject to certain conditions, for magnesium chloride produced by Wendover, with the exception of up to 15,000 short tons per year sold for applications other than dust control, de-icing, and soil stabilization. This agreement is cancelable with two years’ written notice, unless a breach or other specified special event has occurred. Sales prices were specified to the entity in the agreement subject to cost-based escalators. Intrepid is also entitled to certain adjustments in the sale price to the entity based on the final sales price it receives from its customers, as defined by the agreement. Any adjustments in sales price are settled after the entity's fiscal year end in September; however, Intrepid estimates and recognizes earned sales price adjustments each quarter as the amounts are earned and reasonably determinable.

Reclamation Deposits, Surety Bonds, and Sinking Fund—As of March 31, 2013, Intrepid had $17.3 million of security placed principally with the State of Utah and the Bureau of Land Management for eventual reclamation of its various facilities. Of this total requirement, $0.5 million consisted of long-term restricted cash deposits reflected in “Other” non-current assets on the condensed consolidated balance sheets, and $16.8 million was secured by surety bonds issued by an insurer. The surety bonds are held in place by an annual fee paid to the issuer.

Intrepid may be required to post additional security to fund future reclamation obligations as reclamation plans are updated or as governmental entities change requirements.

Legal— Intrepid is subject to litigation. Intrepid has determined that there are no material claims outstanding as of March 31, 2013. Intrepid has established a legal reserve for loss contingencies that are considered probable and reasonably estimable.

ASSET RETIREMENT OBLIGATION

ASSET RETIREMENT OBLIGATION

Intrepid recognizes an estimated liability for future costs associated with the abandonment and reclamation of its mining properties. A liability for the fair value of an asset retirement obligation and a corresponding increase to the carrying value of the related long-lived asset are recorded as the mining operations occur or the assets are acquired.

Intrepid’s asset retirement obligation is based on the estimated cost to abandon and reclaim the mining operations, the economic life of the properties, and federal and state regulatory requirements. The liability is discounted using credit adjusted risk-free rate estimates at the time the liability is incurred or when there are upward revisions to estimated costs. The credit adjusted risk-free rates used to discount Intrepid’s abandonment liabilities range from 6.9% to 8.5%. Revisions to the liability occur due to construction of new or expanded facilities, changes in estimated abandonment costs or economic lives, or if federal or state regulators enact new requirements regarding the abandonment of mines.

Following is a table of the changes to Intrepid’s asset retirement obligations for the following periods (in thousands):

	Three Months Ended March 31,
	2013			2012
Asset retirement obligation, at beginning of period	$	20,579		$	9,708

Accretion of discount	375			181
Total asset retirement obligation, at end of period	$	21,114		$	9,616

The current portion of asset retirement obligations of $1.2 million was included in "Other" current liabilities on the condensed consolidated balance sheets as of March 31, 2013, and December 31, 2012. The undiscounted amount of asset retirement obligation is $53.0 million as of March 31, 2013, of which Intrepid estimates approximately $8.8 million in payments may occur in the next five years.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Intrepid applies the provisions of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification™ (“ASC”) Topic 820, Fair Value Measurements and Disclosures, for all financial assets and liabilities measured at fair value on a recurring basis. The topic establishes a framework for measuring fair value and requires disclosures about fair value measurements. ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The topic establishes market or observable inputs as the preferred sources of values, followed by assumptions based on hypothetical transactions in the absence of market inputs. The topic also establishes a hierarchy for grouping these assets and liabilities, based on the significance level of the following inputs:

• Level 1—Quoted prices in active markets for identical assets and liabilities.

• Level 2—Quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar instruments in markets that are not active, and model‑derived valuations whose inputs are observable or whose significant value drivers are observable.

• Level 3—Significant inputs to the valuation model are unobservable.

As of March 31, 2013, Intrepid did not have any assets or liabilities that were required to be measured at fair value. The following is a listing of Intrepid’s assets and liabilities required to be measured at fair value on a recurring basis and where they are classified within the hierarchy as of December 31, 2012 (in thousands):

			Fair Value at Reporting Date Using
	December 31, 2012		Quoted Prices in Active Markets for Identical Assets or Liabilities (Level 1)		Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Investments
Corporate bonds	$	17,462	$	—	$	17,462	$	—
Certificate of deposit	$	166	$	—	$	166	$	—

Financial assets or liabilities are categorized within the hierarchy based upon the lowest level of input that is significant to the fair value measurement. Below is a general description of Intrepid’s valuation methodologies for financial assets and liabilities, which are measured at fair value and are included in the accompanying condensed consolidated balance sheets.

Intrepid's available-for-sale investments consist of corporate bonds and certain certificates of deposits that are valued using Level 2 inputs. Market pricing for these investments is obtained from an established financial markets data provider.

The methods described above may result in a fair value estimate that may not be indicative of net realizable value or may not be reflective of future fair values and cash flows. While Intrepid believes that the valuation methods utilized are appropriate and consistent with the requirements of ASC Topic 820 and with other marketplace participants, Intrepid recognizes that third parties may use different methodologies or assumptions to determine the fair value of certain financial instruments that could result in a different estimate of fair value at the reporting date.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation—The consolidated financial statements of Intrepid include the accounts of Intrepid and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates—The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Intrepid bases its 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.

Significant estimates include 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 derivative financial instruments, 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 Intrepid’s mineral properties, the useful lives of related property, plant, and equipment, estimates associated with asset retirement obligations, and depreciation expenses. Specific to income tax items, we tend to see significant fluctuations in the valuation of the deferred tax assets and liabilities due to changing state income tax rates and the blend of state tax rates.

Revenue Recognition—Revenue is recognized when evidence of an arrangement exists, risks and rewards of ownership have been transferred to customers, which is generally when title passes, the selling price is fixed and determinable, and collection is reasonably assured. Title passes at the designated shipping point for the majority of sales, but, in a few cases, title passes at the delivery destination. The shipping point may be the plant, a distribution warehouse, a customer warehouse, or a port. Title passes for some international shipments upon payment by the purchaser; however, revenue is not recognized for these transactions until shipment because the risks and rewards of ownership have transferred pursuant to a contractual arrangement. Prices are generally set at the time of, or prior to, shipment. In cases where the final price is determined upon resale of the product by the customer, revenue is deferred until the final sales price is known.

Sales are reported on a gross basis. Intrepid quotes prices to customers both on a delivered basis and on the basis of pick-up at Intrepid’s plants and warehouses. When a sale occurs on a delivered basis, Intrepid incurs and, in turn, bills the customer and records as gross revenue the product sales value, freight, packaging, and certain other distribution costs. Many customers, however, arrange and pay for these costs directly and, in these situations, only the product sales are included in gross revenues.

By-product Credits—When by-product inventories are sold, Intrepid records the sale of by-products as a credit to cost of goods sold.

Inventory and Long-Term Parts Inventory—Inventory consists of product and by-product stocks that are ready for sale; mined ore; potash in evaporation ponds, which is considered work-in-process; and parts and supplies inventory. Product and by-product inventory cost is determined using the lower of weighted average cost or estimated net realizable value and includes direct costs, maintenance, operational overhead, depreciation, depletion, and equipment lease costs applicable to the production process. Direct costs, maintenance, and operational overhead include labor and associated benefits.

Intrepid evaluates its production levels and costs to determine if any should be deemed abnormal and therefore excluded from inventory costs and expensed directly during the applicable period. The assessment of normal production levels is judgmental and is unique to each period. Intrepid models normal production levels and evaluates historical ranges of production by operating plant in assessing what is deemed to be normal.

Parts inventory, including critical spares, that is not expected to be utilized within a period of one year is classified as non-current. Parts and supply inventory cost is determined using the lower of average acquisition cost or estimated replacement cost. Detailed reviews are performed related to the net realizable value of parts inventory, giving consideration to quality, slow-moving items, obsolescence, excessive levels, and other factors. Parts inventories not having turned-over in more than a year, excluding parts classified as critical spares, are reviewed for obsolescence and, if deemed appropriate, are included in the determination of an allowance for obsolescence.

Property, Plant, and Equipment—Property, plant, and equipment are stated at historical cost. Expenditures for property, plant, and equipment relating to new assets or improvements are capitalized, provided the expenditure extends the useful life of an asset or extends the asset’s functionality. Property, plant, and equipment are depreciated under the straight-line method using estimated useful lives. No depreciation is taken on assets classified as construction in progress until the asset is placed into service. Gains and losses are recorded upon retirement, sale, or disposal of assets. Maintenance and repair costs are recognized as period costs when incurred. Capitalized interest, to the extent of debt outstanding, is calculated and assigned to assets that are being constructed, drilled, or built or that are otherwise classified as construction in progress.

Recoverability of Long-Lived Assets—Intrepid evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amount may not be recoverable. An impairment is considered to exist if an asset’s total estimated net future cash flows on an undiscounted basis are less than the carrying amount of the related asset. An impairment loss is measured and recorded based on the discounted estimated future cash flows. Changes in significant assumptions underlying future cash flow estimates or fair values of assets may have a material effect on our financial position and results of operations.

Mineral Properties and Development Costs—Mineral properties and development costs, which are referred to collectively as mineral properties, include acquisition costs, the cost of drilling wells, and the cost of other development work, all of which are capitalized. Depletion of mineral properties is calculated using the units-of-production method over the estimated life of the relevant ore body. The lives of reserves used for accounting purposes are shorter than current reserve life determinations due to uncertainties inherent in long-term estimates. These reserve life estimates have been prepared by us and reviewed and independently determined by mine consultants. Tons of potash and langbeinite in the proven and probable reserves are expressed in terms of expected finished tons of product to be realized, net of estimated losses. Market price fluctuations of potash or Trio^®, as well as increased production costs or reduced recovery rates, could render proven and probable reserves containing relatively lower grades of mineralization uneconomic to exploit and might result in a reduction of reserves. In addition, the provisions of Intrepid’s mineral leases, including royalty provisions, are subject to periodic readjustment by the state and federal government, which could affect the economics of its reserve estimates. Significant changes in the estimated reserves could have a material impact on Intrepid’s results of operations and financial position.

Exploration Costs—Exploration costs include geological and geophysical work performed on areas that do not yet have proven and probable reserves declared. These costs are expensed as incurred.

Asset Retirement Obligation—Reclamation costs are initially recorded as a liability associated with the asset to be reclaimed or abandoned, based on applicable inflation assumptions and discount rates. The accretion of this discounted liability is recognized as expense over the life of the related assets, and the liability is periodically adjusted to reflect changes in the estimates of either the timing or amount of the reclamation and abandonment costs.

Planned Turnaround Maintenance—Each production operation typically shuts down periodically for planned maintenance activities. The costs of maintenance turnarounds at Intrepid's facilities are considered part of production costs and are absorbed into inventory in the period incurred.

Leases—Upon entering into leases, Intrepid evaluates whether leases are operating or capital leases. Operating lease expense is recognized as incurred. If lease payments change over the contractual term or involve contingent amounts, the total estimated cost over the term is recognized on a straight-line basis.

Income Taxes—Intrepid is a subchapter C corporation and therefore is subject to U.S. federal and state income taxes. Intrepid recognizes income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the periods in which the deferred tax liability or asset is expected to be settled or realized. Intrepid records a valuation allowance if it is deemed more likely than not that its deferred income tax assets will not be realized in full. These determinations are subject to ongoing assessment.

Cash and Cash Equivalents—Cash and cash equivalents consist of cash and liquid investments with an original maturity of three months or less.

Investments—Intrepid’s short-term and long-term investments consist of certificates of deposit with various banking institutions, municipal tax-exempt and corporate taxable bonds, and corporate convertible debentures, which have been classified as either held-to-maturity or available-for-sale securities. Short-term investments on the consolidated balance sheets have remaining maturities to Intrepid less than or equal to one year and investments classified as long-term on the consolidated balance sheets have remaining maturities to Intrepid greater than one year. With regard to the financial instruments classified as held-to-maturity investments, they are carried on the consolidated balance sheets at cost, net of amortized premiums or discounts paid. The available-for-sale securities are carried at fair value, with changes in fair value recognized through "Other Comprehensive Loss" on the condensed consolidated balance sheets. Fair value is assessed using a market‑based approach.

Fair Value of Financial Instruments—Intrepid’s financial instruments include cash and cash equivalents, certificate of deposit investments, short-term and long-term investments, restricted cash, accounts receivable, income tax receivables, and accounts payable, all of which are carried at cost, except for available-for-sale investments which are carried at fair value. The remaining investments approximate fair value due to the short-term nature of these instruments. Allowances for doubtful accounts are recorded against the accounts receivable balance to estimate net realizable value. Although there are no amounts currently outstanding under Intrepid’s unsecured credit facility, any borrowings that become outstanding are expected to be recorded at amounts that approximate their fair value as borrowings bear interest at a floating rate.

In April 2013, Intrepid issued $150 million aggregate principal amount of unsecured senior notes ("the Notes"). The Notes bear interest at fixed rates and are deemed to be financial instruments. Accordingly, the fair value of the Notes will be determined on a periodic basis and disclosed. Since considerable judgment is required to develop estimates of fair value, the estimates provided are not necessarily indicative of the precise amounts that could be realized upon the sale, settlement, or refinancing of the instruments.

Earnings per Share—Basic net income per common share of stock is calculated by dividing net income available to common stockholders by the weighted average basic common shares outstanding for the respective period.

Diluted net income per common share of stock is calculated by dividing net income by the weighted average diluted common shares outstanding, which includes the effect of potentially dilutive securities. Potentially dilutive securities for the diluted earnings per share calculation consist of awards of non-vested restricted shares of common stock, non-vested performance units, and non-qualified stock options. The dilutive effect of stock based compensation arrangements are computed using the treasury stock method. Following the lapse of the vesting period of restricted shares of common stock, the shares are considered issued and therefore are included in the number of issued and outstanding shares for purposes of these calculations.

Stock‑Based Compensation—Intrepid accounts for stock-based compensation by recording expense using the fair value of the awards at the time of grant. Intrepid has recorded compensation expense associated with the issuance of non-vested restricted shares of common stock, non-vested performance units, and non-qualified stock options, all of which are subject to service conditions. The expense associated with such awards is recognized over the service period associated with each issuance. Performance units are also subject to operational performance- or market-based conditions.

DERIVATIVE FINANCIAL INSTRUMENTS

Intrepid is exposed to global market risks, including the effect of changes in commodity prices and interest rates. From time to time, Intrepid uses derivatives to manage financial exposures that occur in the normal course of business. Intrepid does not enter into or hold derivatives for trading purposes. While all derivatives had been used for risk management purposes, and were originally entered into as economic hedges, they had not been designated as hedging instruments.

Natural Gas

From time to time, Intrepid manages a portion of its exposure to movements in the market price of natural gas through the use of natural gas derivative contracts. Intrepid had no natural gas derivative contracts outstanding at March 31, 2013.

Interest Rates

Prior to Intrepid's initial public offering in April 2008, Intrepid's predecessor historically managed a portion of its floating interest rate exposure on outstanding debt through the use of interest rate derivative contracts, as required by its credit agreement. Intrepid repaid its assumed debt obligations immediately subsequent to the closing of its initial public offering and, in the year ended December 31, 2012, settled in the ordinary course of business its positions in the derivative financial instruments also assumed from its predecessor.

The following table presents the amounts of gain or (loss) recognized in income on derivatives affecting the condensed consolidated statement of operations for the periods presented (in thousands):
