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 and magnesium chloride.

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, including the brine injection system, and has placed potash-enriched brine into all of the newly constructed solar evaporation ponds. Intrepid expects to begin producing potash from the HB Solar Solution mine after the construction of the mill is completed in late 2013.

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 centrally 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, but are not limited to, those for proven and probable mineral reserves, the related present value of estimated future net cash flows, useful lives of plant assets, asset retirement obligations, normal inventory production levels, inventory valuations, the valuation of equity awards, the valuation of derivative financial instruments, the valuation of receivables, 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 experience 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,

6

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 that have not 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 capitalized on 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.

7

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 condensed 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 "Accumulated other comprehensive income" 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, short-term and long-term investments, restricted cash, accounts receivable, refundable income taxes, and accounts payable. These instruments are carried at cost, which approximates fair value due to the short-term maturities of the instruments. All available-for-sale investments are carried at fair value. Allowances for doubtful accounts are recorded against the accounts receivable balance to estimate net realizable value. The fair value of the long-term debt is estimated using discounted cash flow analysis based on current borrowing rates for debt with similar remaining maturities and ratings. Although there are no amounts currently outstanding under Intrepid’s unsecured credit facility, any borrowings that become outstanding would bear interest at a floating rate and therefore be recorded at their estimated fair value.

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.

8

Note 3 — EARNINGS PER SHARE

Dilutive securities, including stock options, non-vested restricted stock and performance units, are excluded from the diluted weighted average shares outstanding computation in periods in which they have an anti-dilutive effect, such as when there is a net loss. 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 September 30, 2013, and 2012, a weighted average of 277,284 and 123,237 non-vested shares of restricted common stock and 342,495 and 197,896 stock options, respectively, were anti-dilutive and therefore were not included in the diluted weighted average share calculation. For the nine months ended September 30, 2013, and 2012, a weighted average of 171,058 and 114,285 non-vested shares of restricted common stock and 310,471 and 191,299 stock options, respectively, 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):

Certificates of deposit and time deposits	166		—		—			166
Total available-for-sale securities	$	17,676	$	14	$	(62	)	$	17,628

The fair values of Intrepid's investments in corporate bonds are below their respective costs due to recent increases in short-term interest rates. However, Intrepid considers the unrealized losses on these investments to be temporary given Intrepid's current plans to hold the investments. These investments have been classified as available-for-sale. For the three and nine months ended September 30, 2013, Intrepid's available-for-sale investments had gross realized gains of approximately $12,000 and $48,000, respectively. For the three and nine months ended September 30, 2013, Intrepid recognized gross realized losses of zero and approximately $19,000, respectively, on investments classified as available-for-sale. For the three and nine months ended September 30, 2012, no investments were classified as available-for-sale.

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 September 30, 2013, and December 31, 2012, respectively (in thousands):

Note 7 — DEBT

11

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. The facility was amended in August 2013 to extend the maturity date by two years to August 2018, to decrease the applicable interest rates on any borrowings, to decrease the quarterly commitment fees, and to increase the maximum allowable leverage ratio to 3.5. The minimum allowable fixed charge coverage ratio under the facility remains at 1.3.

Under the facility, the leverage ratio is defined as the ratio of total funded indebtedness to adjusted EBITDA (earnings before interest, income taxes, depreciation, amortization, and certain other expenses) for the prior four fiscal quarters. The fixed charge coverage ratio is defined as the ratio of adjusted EBITDA for the prior four fiscal quarters to fixed charges. Both ratios may operate to limit the total amount available to Intrepid under the facility.

The facility is unsecured and is guaranteed by Intrepid's material subsidiaries. There were no amounts outstanding under the facility, and the full amount of the facility was available to Intrepid, as of September 30, 2013, and December 31, 2012.

Unsecured Senior Notes—In April 2013, Intrepid issued $150 million aggregate principal amount of unsecured senior notes ("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 is paid semiannually on April 16 and October 16 of each year, beginning on October 16, 2013. Interest expense is recorded net of any capitalized interest associated with investments in capital projects. Intrepid incurred gross interest expense for the three months ended September 30, 2013, and 2012, of $1.7 million and $0.2 million, respectively. Intrepid incurred gross interest expense for the nine months ended September 30, 2013, and 2012, of $3.3 million and $0.7 million, respectively. Intrepid capitalized $1.4 million and $2.6 million of interest during the three and nine months ended September 30, 2013. Intrepid had no capitalized interest in 2012.

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 or reclamation of mines.

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

12

	Three Months Ended September 30,					Nine Months Ended September 30,
	2013			2012		2013			2012
Asset retirement obligation, at beginning of period	$	21,532		$	10,236	$	20,579		$	9,708
Liabilities settled	(174		)	—		(302		)	(273		)
Liabilities incurred	19			—		351			—
Changes in estimated obligations	—			359		—			798
Accretion of discount	375			181		1,124			543
Total asset retirement obligation, at end of period	$	21,752		$	10,776	$	21,752		$	10,776

The current portion of asset retirement obligations of $1.0 million and $1.2 million was included in "Other" current liabilities on the condensed consolidated balance sheets as of September 30, 2013, and December 31, 2012. The undiscounted amount of asset retirement obligation is $53.6 million as of September 30, 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"). Intrepid has issued common stock, restricted shares of common stock, performance units, and non-qualified stock option awards under the Plan. As of September 30, 2013, the following awards were outstanding under the plan: 372,503 shares of non-vested restricted shares of common stock; 97,367 non-vested performance units representing shares of common stock; and options to purchase 338,744 shares of common stock. As of September 30, 2013, approximately 3.6 million shares of common stock remained 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 was $0.9 million and $0.6 million for the three months ended September 30, 2013, and 2012. Total compensation expense related to the non-vested restricted shares of common stock awards was $2.6 million and $2.5 million for the nine months ended September 30, 2013, and 2012. These amounts are net

13

of estimated forfeiture adjustments. As of September 30, 2013, there was $5.9 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 nine months ended September 30, 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	235,490		$	19.25
Vested	(88,186	)	$	27.12
Forfeited	(15,558	)	$	22.16
Non-vested restricted shares of common stock, end of period	372,503		$	21.65

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 September 30, 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 September 30, 2013, and 2012, Intrepid recognized stock‑based compensation related to performance units of approximately $0.2 million and $0.1 million, respectively. For the nine months ended September 30, 2013, and 2012, Intrepid recognized stock‑based compensation related to performance units of approximately $0.5 million and $0.2 million, respectively. As of September 30, 2013, there was $0.7 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 September 30, 2013, and 2012, Intrepid recognized stock‑based compensation related to previously issued stock options of approximately $0.1 million and $0.3 million, respectively. For the nine months ended September 30, 2013, and 2012, Intrepid recognized stock‑based compensation related to previously issued stock options of approximately $0.5 million and $0.9 million, respectively. As of September 30, 2013, there was $0.2 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 September 30, 2013, is as follows:

14

	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	338,744	$26.25	$—	6.1	$13.13
Vested or expected to vest, end
of period	337,643	$26.22	$—	6.1	$13.11
Exercisable non-qualified
stock options, end of period	308,434	$25.33	$—	6.0	$12.50

(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 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 effect of the depletion and domestic production activities deduction and research and development credits. Intrepid’s effective tax rate for the nine months ended September 30, 2013, and 2012 was 35.4% and 32.8%, respectively. Intrepid believes the effective tax rate for the nine months ended September 30, 2013, is more meaningful than the effective rate for the three months ended September 30, 2013. During the three months ended September 30, 2013,  the estimated depletion and domestic production activities deductions had a more pronounced impact on the effective rate due to the normal recurring update to Intrepid’s estimated before tax income amount for the 2013 calendar year.

A summary of the provision for income taxes is as follows (in thousands):

	Three Months Ended September 30,					Nine Months Ended September 30,
	2013			2012		2013			2012
Current portion of income tax (benefit) expense	$	(1,123	)	$	3,576	$	(780	)	$	7,260
Deferred portion of income tax expense	773			7,109		16,299			28,350
Total income tax (benefit) expense	$	(350	)	$	10,685	$	15,519		$	35,610

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. As a result, Intrepid recorded additional deferred state income tax expense of $1.3 million in the second quarter of 2013, as its deferred tax asset had decreased in value. 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.

Reclamation Deposits and Surety Bonds—As of September 30, 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

15

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.

New Mexico Employment Credits—Since September 2011, Intrepid has recorded, and continues to record, the value of estimated refundable employment-related credits for qualified wages paid in New Mexico. Intrepid began recognizing these credits in the financial statements at the point in time that previous tax credit filings had been approved and paid by the State of New Mexico, thereby confirming that the criteria for recognition was deemed probable and reasonably estimable. Since that time, the estimated recoverable value of these credits has been, and continues to be, reflected as a reduction to our production costs and amounts yet to be collected are recorded in “Other receivables, net” in the condensed consolidated balance sheets in the same period in which the credit is earned.

In the third quarter of 2013, the New Mexico Taxation and Revenue Department denied Intrepid's application to receive the New Mexico High Wage Jobs Credit for certain prior years' filings.  Intrepid believes the denial is improper and intends to vigorously pursue recovery of these credits.  Nonetheless, Intrepid has recorded a reserve of approximately $2.8 million for credits relating to the denied periods in order to reflect the denial of the claimed credits.  As the inventory associated with the denied credits for periods prior to 2012 has since been sold, Intrepid recorded the expense associated with recording the reserve as an "Other expense" in Operating income in the condensed consolidated statement of operations for the three months ended September 30, 2013. The value of credits associated with 2012 and 2013 have been established as a net receivable as of September 30, 2013, and is reflected in "Other receivables, net" in the condensed consolidated balance sheets.

Legal—Intrepid is subject to litigation. Intrepid has determined that there are no material claims outstanding as of September 30, 2013. Intrepid has established a legal reserve for loss contingencies that are considered probable and reasonably estimable.

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

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

2013
Three months ended September 30, 2013	$	1,091
Nine months ended September 30, 2013	$	3,115

Three months ended September 30, 2012	$	1,189
Nine months ended September 30, 2012	$	2,970

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 September 30, 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

16

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.

Intrepid did not have any derivative instruments outstanding during the first nine months of 2013. The table below presents the amounts of gain or (loss) recognized in income on derivatives affecting the condensed consolidated statement of operations for the periods presented in 2012 (amounts in thousands):

	Location of gain (loss) recognized in income on derivative	Three Months Ended September 30, 2012			Nine Months Ended September 30, 2012
Derivatives not designated as hedging instruments
Interest rate contracts:
Realized loss	Interest expense	$	(280	)	$	(821	)
Unrealized gain	Interest expense	272			769
Total loss	Interest expense	$	(8	)	$	(52	)

Please see Note 13— Fair Value for a description of how the above financial instruments were valued.

Note 13 — FAIR VALUE

Assets Measured at Fair Value—Fair value accounting establishes a fair value hierarchy that prioritizes the inputs to the valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

• 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.

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 September 30, 2013, and December 31, 2012 (in thousands):

			Fair Value at Reporting Date Using
	September 30, 2013		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	$	68,199	$	—	$	68,199	$	—

17

			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 on the 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 used are appropriate and consistent with the requirements of ASC Topic 820 and the methods used by 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.

Financial Instruments—The carrying values and fair values of our financial instruments as of September 30, 2013, and December 31, 2012, are as follows (in thousands):

	September 30, 2013				December 31, 2012
	Carrying Value		Fair Value		Carrying Value		Fair Value
Cash and cash equivalents	$	10,446	$	10,446	$	33,619	$	33,619
Certificate of deposits	$	2,260	$	2,260	$	6,666	$	6,666
Accounts receivable	$	33,762	$	33,762	$	40,630	$	40,630
Refundable income taxes	$	4,505	$	4,505	$	3,306	$	3,306
Accounts payable	$	22,094	$	22,094	$	19,634	$	19,634

For cash and cash equivalents, certificate of deposit investments, accounts receivable, refundable income taxes, and accounts payable, the carrying amount approximates fair value because of the short-term maturity of those instruments. The fair value of the long-term debt is estimated using discounted cash flow analysis based on current borrowing rates for debt with similar remaining maturities and ratings (a Level 2 input) and is designed to approximate the amount at which the instruments could be exchanged in an arm's length transaction between knowledgeable willing parties.

Note 14 — EMPLOYEE BENEFITS

Defined Benefit Pension Plan—In December 2011, Intrepid adopted resolutions to terminate the Moab Salt, L.L.C. Employees' Pension Plan, a defined benefit pension plan, which was acquired in conjunction with the purchase of its Moab assets in 2000. After receiving the necessary regulatory approvals, plan amendments, and participant settlement elections, Intrepid funded $2.0 million to settle all pension plan liabilities in April 2013. Upon funding, Intrepid was released from any further obligations under the pension plan. Accordingly, Intrepid recorded the additional expense of approximately $1.9 million to reflect the termination of the pension plan in the nine months ended September 30, 2013. This amount is recorded as "Other income (expense)" in the condensed consolidated statement of operations and represents 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. The components of the net periodic pension expense are set forth below (in thousands):

Note 16 — RECOGNITION OF COMPENSATING TAX REFUND

In the second quarter of 2013, Intrepid received a refund from the State of New Mexico related to a compensating tax refund submitted for the period from December 2008 to October 2011. This refund consists of items for which Intrepid made compensating tax payments on behalf of vendors, as well as compensating tax payments on construction-related and service items during a period when the law was deemed unconstitutional. Upon receipt of the refund, which removed uncertainty about the amount and collection of the refund, Intrepid recorded $1.7 million of income, which is reflected in "Other expense" included in Operating income in the condensed consolidated statement of operations for the nine months ended September 30, 2013.

Note 17 — 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 Intrepid's consolidated financial position, results of operations, or cash flows.

In July 2013, FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The new guidance prescribes the balance sheet presentation of unrecognized tax benefits relating to net operating loss carryforwards or similar items. ASU 2013-11 is effective for fiscal years beginning after December 15, 2013. Intrepid does not anticipate a material impact on its consolidated financial statements upon adoption.

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

21

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. These by-product credits have represented approximately 2% - 3% of total cost of goods sold in each of the last three years.

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. Each of our operating facilities supplies these markets. Additionally, we have the capability to supply customers from our different locations due to the relatively homogeneous nature of our products. 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 centrally, including our freight and logistics planning. 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 goal 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 an additional solar solution mine that is under construction in Carlsbad, New Mexico, called the HB Solar Solution mine. 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, and approximately 240,000 tons of langbeinite, based on current design. Actual production is affected by operating rates, recoveries, mining rates, ore grade and ore characteristics, mill performance, precipitation, evaporation rates at our solar solution operations, and the amount of mine development work that we perform. Therefore, our production results tend to be lower than our productive capacity. Currently, we are not producing at these levels primarily due to lower grade ore being delivered to the mill at our East facility and lower-than-designed recovery levels at our West facility. 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; investments to extend the life of our solar solution mining assets; and potential development of reserves using the North mine infrastructure, which was operated as a traditional underground mine until the early 1980s.

Significant Business Trends and Activities

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

• Potash demand. We sold 156,000 tons of potash in the third quarter 2013, a decline of 93,000 tons compared with the third quarter of 2012. Our third quarter 2013 sales volumes were impacted by general cautiousness from dealers resulting from a lack of immediate demand by retailers and farmers. This lack of demand resulted primarily from uncertainty surrounding the price of potash after Uralkali's announcement in July 2013 that it would be withdrawing from the Belarus Potash Corporation ("BPC") marketing arrangement and Uralkali's subsequent announcement of its intention to increase its production and sales volumes. These announcements caused widespread speculation that the price of potash was going to decline significantly. This speculation created uncertainty and, in turn, a lack of purchasing globally. Our sales results, when compared with sales results in the prior year, were also impacted by the timing of the fall harvest season. The 2012 harvest season was earlier than normal due to hot, dry weather. The 2013 harvest season, by contrast, began in late September due to a cold, wet spring. As a result, dealers delayed their potash fill programs as farmers did not have a strong sense of urgency in taking a position on potash during the third quarter. As crops are now reaching maturity and harvesting has begun, we are beginning to see more purchasing and application activity in North

22

America. Ultimately, we believe our 2013 fourth quarter sales volumes will be dependent on the duration of the fall application season, as well as our ability to deliver product to our customers on a timely basis.

The specific timing of when farmers apply potash remains highly weather dependent and varies across the numerous growing regions within the United States. In addition, potash demand is significantly influenced by dealer storage volumes and the marketing programs of potash retailers. The combination of these items results in variability in potash sales and shipments, 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 $363 per ton in the third quarter of 2013 from $444 per ton in the third quarter of 2012. This decrease was due to the continued downward pressure on potash prices driven by the Uralkali announcements discussed previously, softness in global potash demand and the general view in the market that there is adequate global potash supply as noted above. Uncertainty around global potash sales levels, especially into large international markets such as China and India, has also put pressure on domestic potash prices. The new contracts for potash deliveries into China and India have not been announced, which creates temporary situations where the suppliers to these markets build inventory and have to manage production volumes. These pressures and the ongoing uncertainty in the world economy continue to cloud the long-term global potash market. Further, North American potash inventory levels remain above the five-year average, which may also have an impact on pricing. In the third quarter, and continuing early in the fourth quarter, sales levels and pricing have been soft as dealers appear to be postponing fertilizer purchases in response to the short-term market uncertainty caused by these global concerns about the balance between supply and demand.

• Trio^® prices and demand. The average net realized sales price of Trio^® increased to $353 per ton in the third quarter of 2013 from $336 per ton in the third quarter of 2012. Trio^® domestic pricing has historically tended to move in a relatively close correlation to potash pricing. Over the last year, dealers' and farmers' recognition of the added value of magnesium and sulfate and the low-chloride benefits from this specialty product has translated into higher prices despite sequentially lower potash prices. Our average net realized sales price for Trio^® decreased from $359 per ton in the second quarter of 2013 to $353 per ton in the third quarter of 2013. Demand for granular-sized Trio^® continues to exceed production, which has also been supportive of Trio^® pricing. Demand for standard-sized Trio^®, however, has been less predictable. We expect that the general softness in the potash market, combined with a decrease in the market price for sulfur, will have a directional impact on pricing for our standard-sized Trio^®.

• Major capital projects. 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 and, as of September 30, 2013, all of our solar evaporation ponds were full of potash-enriched brine. We utilize solar energy to evaporate the potash-enriched brine in our evaporation ponds and expect to process potash through our processing mill after construction is completed. The construction of the processing plant is on a tight schedule and is expected to be completed and placed into initial service late in 2013. Initial commissioning of the processing plant is expected late in the fourth quarter and will continue through much of 2014. The total expected investment for the project is between $235 million and $245 million, of which $208.7 million had been invested as of September 30, 2013.

The construction of the new North compaction facility is nearing completion with $91.6 million of the $95 million to$100 million invested through September 30, 2013. Construction work for two of the three compactor lines is complete and these two lines have commenced production. We expect that we will have fluctuation in our production volumes through the new North compaction facilities throughout the first year of operation as our commissioning activities continue. We anticipate that the third line will become operational in the first quarter of 2014. This new facility expands our granulation capacity to accommodate the increased tonnage expected from the HB Solar Solution mine and ongoing upgrades at our West facility. The new facility will use state-of-the-art equipment to enable us to produce high quality granular product.

We have several ongoing projects at the West facility with total expected investment of approximately $30 million to $40 million, with $16.5 million invested through September 30, 2013. The projects underway at the West facility, some of which began in 2012, are intended to sustain and increase production by addressing the lower recoveries experienced at the West facility in recent quarters as we transition into different ore zones that are more difficult to process. The majority of these projects are expected to be completed in early 2014. The capabilities of the new North compaction facility now allow us the flexibility to make design changes at the West facility to increase recovery. There is a level of coordination among the projects at the West facility and North compaction facility that will cause some variation in production at the West facility as the projects are placed in service and resulting design changes are realized.

23

We continue to develop additional solution mining opportunities at our Moab facility by expanding our producing cavern systems. In October 2013, we completed the drilling activities on our third multi-lateral cavern system. We will begin brine injection into the new cavern system during the fourth quarter. We expect this cavern system will provide higher grade extraction brines that will offset the typical decreasing production profile as other cavern systems are depleted and will allow for incremental production opportunities in future years. The total capital investment for this project is expected to be between $20 million and $25 million, of which $17.0 million had been invested through September 30, 2013.

• East facility production. We have dedicated significant resources to the long-term improvement plan that we began in early 2012 to address production challenges at the East facility. Execution of the long-term improvement plan is expected to continue throughout 2013. At our East facility, our recovery and production of both potash and langbeinite are directionally impacted by the ore grade and the development work we do in the mine's complex mixed ore zones. During the third quarter of 2013, our production of both potash and langbeinite declined from the second quarter of 2012 as we encountered lower grades within the mixed ore zones in which we were mining. As a result, we incurred higher production costs, which were allocated over fewer production tons, thereby resulting in higher per-ton cost of goods sold and a lower of cost or market inventory charge. Subsequent to the third quarter, we have made operational changes that have resulted in slightly improved ore grades. As we transition into different mining zones in the fourth quarter, we expect ore grades will continue to be lower compared with the ore grades from the comparable period in 2012. Production costs may be further impacted by the planned annual maintenance activities at our East facility that occurred in October. As a consequence of the production results in the third quarter of 2013, combined with decreased potash prices, we recorded lower of cost or market adjustments of approximately $2.1 million on the remaining inventory at our East facility. We expect the directional relationship between ore grades and development activities and production will continue to influence our results from our East facility.

• Other Expense (Income). In the third quarter of 2013, our application for certain New Mexico employment-related tax credits was denied. We believe the denial is improper and we intend to vigorously pursue recovery of these credits. Nonetheless, we recorded a reserve of approximately $2.8 million for tax credits relating to the denied credits.

Selected Operating and Financial Data

The following tables present 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 for the third quarter of 2013 was $2.0 million, or $0.03 per share, and cash flows from operations were $14.7 million. Net income for the first nine months of 2013 was $28.3 million, or $0.37 per share, with cash flows from operations of $62.1 million. During the quarter ended September 30, 2013, we sold 156,000 tons of potash at a net realized sales price of $363 per ton and 22,000 tons of Trio^® at a net realized sales price of $353 per ton. During the nine months ended September 30, 2013, we sold 525,000 tons of potash at a net realized sales price of $396 per ton and 96,000 tons of Trio^® at a net realized sales price of $354 per ton. We made capital investments of $190.1 million in the first nine months of 2013, received $149.3 million of net proceeds from the issuance of unsecured senior notes in April 2013, and ended the quarter with $80.9 million of cash and investments. We produced 571,000 tons of potash and 136,000 tons of langbeinite

in the nine months ended September 30, 2013.

Potash

We sold 156,000 tons of potash in the third quarter of 2013 compared with 249,000 tons in the third quarter of 2012. For the first nine months of 2013, we sold 525,000 tons of potash compared with 636,000 tons in the first nine months of 2012. The decline in sales volumes was driven by general cautiousness from dealers resulting from of a lack of immediate demand by retailers and farmers due to Uralkali's announcements and the late fall harvest season, each discussed previously. Our average net realized sales price of potash was $363 per ton in the third quarter of 2013, compared with $444 per ton in the third quarter of 2012. The overall pricing of dry fertilizers, including potash, continued to come under pressure due to uncertainty surrounding increased global potash supply and discounting of product through summer fill programs with North American producers, and North American inventory levels that were above the five-year average.

The table below shows our potash sales mix for the three and nine months ended September 30, 2013, and 2012. The percentage of sales into the industrial market increased in 2013 compared with 2012, as a result of an increase in sales of standard-sized potash for industrial purposes.

	Three Months Ended September 30,		Nine Months Ended September 30,
	2013	2012	2013	2012
Agricultural	67%	84%	73%	81%
Industrial	25%	10%	19%	12%
Feed	8%	6%	8%	7%

We continue to focus on increasing the flexibility of our operations to produce the right amount of product for the demands of our specific markets. For example, we have invested in granulation facilities at each of our operations. The flexibility to produce more granular-sized product 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, domestic potash consumption 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 a decline in soil potassium which will lead to an increasing potassium deficiency of some agricultural soils in North America. In order for the North American farmer to maximize yields, we believe the application of higher rates of potash will be necessary in the future. With higher crop yields in 2013, more potassium was removed from the soil. We believe replenishment of potassium prior to the seeding of the 2014 crop will be an important factor in maximizing 2014 yields. We anticipate the fall potash application season will be a higher priority for farmers given the soil depletion and current crop economics.

Our production volume of potash in the third quarter of 2013 decreased to 167,000 tons, compared with 189,000 tons produced in the third quarter of 2012. This decrease was largely driven by lower production at our East and West

27

facilities, offset by a modest increase in production at our Wendover facility. As discussed above, we are currently mining more complex ore zones at our East facility, which has impacted the quality of the material delivered to the mill and reduced our potash production. We continually re-evaluate our mine plans in order to manage our plant operations to match the ore being delivered to the surface. Production from our West facility has been impacted by recovery challenges prior to completion of certain capital projects at West that are designed to increase recoveries. Due to the reduced production levels at our East and West facilities, we had fewer tons of potash produced over which to allocate production costs. As a result, our cash operating cost of goods sold increased to $198 per ton for the third quarter of 2013, compared with $167 per ton in the third quarter of 2012.

Trio^® 

Our Trio^® production was higher in the first nine months of 2013 than in the same period in 2012 as we benefited from incremental operating improvements associated with the long-term improvement plan at our East facility. Pricing and demand for this specialty product remains strong, particularly for our granular-sized product. Our sales of Trio^® decreased to 22,000 tons in the third quarter of 2013 as compared with 27,000 tons in the third quarter of 2012. Production exceeded sales and, as a result, we had a slight inventory build, primarily in standard-sized Trio^®. We are managing our business to more traditional inventory levels in preparation for fall and spring application season activity. The lower grade ore delivered to the East plant has, however, impacted our overall Trio^® production rates as well. We have begun to see general improvements in the quality and production levels of our pelletized product as a result of our long-term improvement plan at the pelletization plant. This work on the pellet circuit is ongoing and has led to a temporary situation where we have experienced increased inventory levels for our standard-sized Trio^® product.

For the third quarter of 2013, as compared with the third quarter of 2012, our average Trio^® gross margin per ton decreased by $34 per ton as our average net realized sales price for Trio^® increased by $17 per ton, which was more than offset by an increase in our cash cost of goods sold for Trio^® of $46 per ton. Our cash cost of goods sold for Trio^® increased as a result of the production issues mentioned above. The cash costs per ton have also been negatively affected by the inefficiency and resulting high cost per ton associated with the production of the pelletized product. This resulted in a higher per-unit cash cost per ton associated with the pelletized product. As the market for granular and pelletized Trio^® remains strong, we will continue to develop our operating practices to improve the yield and productivity of this production facility.

Our export sales of Trio^® tend to be in larger quantities and with more variability as to the timing of those sales, which has an impact on the 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 $39 per ton in the third quarter of 2013 from the second quarter of 2013 largely as a result of uncertainty in the global potash markets after Uralkali announced its departure from the BPC marketing arrangement, as discussed previously. Domestically, the market continues to experience ongoing price pressure, including lower summer fill program offerings from the North American potash producers. This also had an effect on domestic potash pricing.

We market Trio^® as a specialty product. As farmers have increasingly recognized the agronomic value of this product, demand for the product has grown and we have enjoyed a higher market price through 2012 and into 2013. This

28

recognition has resulted in pricing that more closely reflects the tight supply of this product and the nutrient value of this product.

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

Specific Factors Affecting Our Results

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. Although our gross sales include the freight that we bill, 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. Rail freight rates have been steadily increasing, thereby negatively influencing our net realized sales prices. 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, sales, and production levels at our facilities.

Our production costs per ton are also impacted when our production levels change, due to factors such as changes in the grade of ore delivered to the plant, levels of mine development, plant operating performance, downtime, and annual maintenance turnarounds. We expect that our labor and contract labor costs in Carlsbad, New Mexico, will 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. This complex ore is processed through a singular product flow at the surface facility. The specific grade, volume, and characterization of the ore that is mined at any particular time influences the

29

amount of tons of potash and langbeinite ultimately produced from the facility, which affects our production costs per ton for both products and affects our quarter-to-quarter results.

We pay royalties to federal, state, and private lessors under our mineral leases. These payments typically equal 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 that varies with the grade of ore extracted. For the three and nine months ended September 30, 2013, our average royalty rate was 1.0% and 3.4%, respectively. During the three months ended September 30, 2013, we recorded certain reductions for royalty expense, which artificially lowered the average royalty rate in the third quarter. We believe that the average royalty rate in the third quarter of 2013 is not representative of future trends and, rather, that the year-to-date result is more indicative. For the three and nine months ended September 30, 2012, our average royalty rate was 3.8% in each period. We expect that future average royalty rates will increase modestly from rate experienced in the nine months ended September 30, 2013, 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. Our effective tax rate for the nine months ended September 30, 2013, and 2012 was 35.4% and 32.8%, 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 and research and development credits. Our federal and state income tax returns are subject to examination by federal and state tax authorities.

During the three months ended September 30, 2013, we recognized an income tax benefit of $0.4 million compared with income tax expense of $15.5 million during the nine months ended September 30, 2013. Total tax expense for the three months ended September 30, 2013, was comprised of $1.1 million of current income tax benefit and $0.7 million of deferred income tax expense. Total tax expense for the nine months ended September 30, 2013, was comprised of $0.8 million of current income tax benefit and $16.3 million of deferred income tax expense. For the three and nine months ended September 30, 2012, the total tax expense was $10.7 million and $35.6 million, respectively. Total tax expense for the three months ended September 30, 2012, was comprised of $3.6 million of current income tax expense and $7.1 million of deferred income tax expense. Total tax expense for the nine months ended September 30, 2012, was comprised of $7.3 million of current income tax expense and $28.3 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 impact of accelerated tax bonus depreciation and the utilization of percentage depletion.

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% 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. Accordingly, during the second quarter of 2013, we increased our deferred state tax provision expense by approximately $1.3 million in response to this state tax rate change. Because this state tax rate comprises a significant portion of our state income tax rate and 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 and have been executing 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. Likewise, as we invest in our facilities, we seek to deploy capital while maintaining sufficient liquidity to react strategically to market conditions.

30

Much of our strategic focus in 2013 has been on investing in our large capital projects, which are now nearing completion. 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 these projects are completed, we expect to reduce our capital investments, allowing us to shift our focus to the optimization and efficiencies of our operating facilities and to extract the value from the capital investments made over the last several years. This reduction in capital investment is anticipated to begin when the HB Solar Solution mine processing plant is placed in service.

In the first nine months of 2013, we invested $190.1 million in capital projects. The total capital investment in 2013 is estimated to be between $245 million and $265 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. We are also focusing on several smaller projects which are designed to collectively improve throughput and recoveries at our West facility with much of this capital being invested in the remainder of 2013 and the first half of 2014. The actual level of capital investment for 2013 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 the proceeds from the $150 million unsecured senior notes (the "Notes") received in April 2013.

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. All of our solar evaporation ponds are complete and contain potash-enriched brine. The total expected investment for the project is estimated to be between $235 million and $245 million, of which $208.7 million had been invested as of September 30, 2013. We currently expect initial limited production of finished product from the HB Solar Solution mine to occur following completion of the processing plant near the end of 2013. We expect our production from the HB Solar Solution mine to ramp up throughout 2014, with production levels increasing into the harvest seasons in 2015 and 2016, assuming the benefit of an average annual evaporation cycle applied to full evaporation ponds. The anticipated production schedule may be impacted by delays in plant construction, the timing of critical equipment deliveries, the rate of injection into the mines, and the impact of weather events or patterns on construction or evaporation seasons.

• The North compaction project is nearing completion. The first two compaction lines are in service and the third compaction line is expected to be completed in the first quarter of 2014. This project is designed to 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 through September 30, 2013, was approximately $91.6 million. The total capital investment for this project is anticipated to be between $95 million and $100 million.

• There are several ongoing projects at our West facility that are intended to sustain and increase production through improvements in recovery rates. We have made ongoing improvements to the West facility since its acquisition to increase the volume of tons going through the facility. This next phase of improvements is designed to address the lower recoveries experienced at the West facility in recent quarters as we transition into different ore zones that require different processing techniques. The majority of these projects are expected to be completed in early 2014 with operational improvements beginning to ramp up in 2014. The capabilities of the new North compaction facility now allow us to make design changes that increase recovery. Accordingly, there is a level of coordination among the projects at the West facility and North compaction facility that will cause some interruptions in production at the West facility as the projects are placed in service and resulting design changes are realized. We estimate the total investment for these projects will be between $30 million and $40 million, of which $16.5 million had been invested as of September 30, 2013.

• We have developed additional solution mining opportunities at our Moab facility. We completed the development of our second horizontal cavern system in the fourth quarter of 2012. In October 2013, we completed the drilling on our third multi-lateral cavern system and we will begin injecting brine into this cavern system during the fourth quarter. We expect this cavern system will provide higher grade extraction brines, which will offset the typical production profile as other cavern systems are depleted and allow for incremental production opportunities. This project is expected to involve total capital investment of approximately $20 million to $25 million, of which $17.0 million had been invested as of September 30, 2013.

Liquidity and Capital Resources

As of September 30, 2013, we had cash, cash equivalents, and investments of $80.9 million 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 $80.9 million of cash, cash equivalents and investments at September 30, 2013, was made up of the following:

• $4.8 million in cash

• $5.6 million in cash equivalent investments, consisting of money market accounts with banking institutions that we believe are financially sound

• $40.7 million and $29.8 million invested in short and long-term investments, respectively

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. The total amount available to us under the credit facility could be limited if our adjusted EBITDA (earnings before interest, income taxes, depreciation, amortization, and certain other expenses, as defined in the credit facility) decreased significantly over several quarters, as discussed in more detail below under the heading "Unsecured Credit Facility." The following summarizes our cash flow activity for the nine months ended September 30, 2013, and 2012:

	Nine Months Ended September 30,
	2013			2012
	(In thousands)
Cash Flows from Operating Activities	$	62,127		$	132,320
Cash Flows from Investing Activities	$	(233,691	)	$	(149,859	)
Cash Flows from Financing Activities	$	148,391		$	(718	)

Operating Activities

Total cash provided by operating activities through September 30, 2013, was $62.1 million, a decrease of $70.2 million compared with the first nine months of 2012. The primary driver of this decline was lower sales volumes and a lower average net realized sales price for potash, as discussed previously, which, together, resulted in lower net income. Cash provided by operating activities for the nine months ended September 30, 2013, was negatively impacted by an increase in inventory of $39.4 million as inventory levels and per-ton net production costs increased.

Investing Activities

Total cash used in investing activities increased $83.8 million in the first nine months of 2013 compared with the comparable period in 2012 as a result of lower proceeds from investments and an increase in cash used for capital investments. The decline in proceeds from investments was the result of the timing of corporate bond maturities in our investment portfolio. The increase in cash used for capital investments was driven by the major capital projects we currently have underway, as discussed previously.

Financing Activities

Total cash provided by financing activities of $148.4 million primarily consisted of proceeds from long-term debt related to the funding of our Notes in April 2013, which have an aggregate principal amount of $150 million.

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 revolving credit facility of $250 million. The facility was amended in August 2013 to extend the maturity date by two years to August 2018, to decrease the applicable interest rates on any borrowings, to decrease our quarterly commitment fees, and to increase our maximum allowable leverage ratio to 3.5. Our minimum allowable fixed charge coverage ratio under the facility remains at 1.3.

Under the facility, the leverage ratio is defined as the ratio of our total funded indebtedness to our adjusted EBITDA (earnings before interest, income taxes, depreciation, amortization, and certain other expenses) for the prior four fiscal quarters. The minimum allowable fixed charge coverage ratio is defined as the ratio of adjusted EBITDA for the prior four

32

fiscal quarters to fixed charges. Both ratios may operate to limit the total amount available under the facility. For example, if adjusted EBITDA decreased significantly over several quarters with no change to indebtedness, our leverage ratio could rise to the level where some or all of the $250 million would not be available to us.    

The facility is unsecured and is guaranteed by our material subsidiaries. There were no amounts outstanding under the facility, and the full amount was available to us, as of September 30, 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 1.125% and 2.25%, depending upon our leverage ratio, as defined above; or (2) an alternative base rate, plus a margin of between 0.125% and 1.25%, 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 0.15% 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 received net proceeds of $149.3 million from the issuance of $150 million aggregate principal amount of the Notes pursuant to a note purchase agreement entered into in August 2012. 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 is paid semiannually on April 16 and October 16 of each year.

Contractual Obligations

As of September 30, 2013, we had contractual obligations totaling $289.5 million on an undiscounted basis, as indicated below. Contractual commitments shown are for the full calendar year unless otherwise indicated.

(1) Intrepid issued $150 million aggregate principal amount of the Notes on April 16, 2013. The Notes mature in three tranches in 2020, 2023, and 2025.

(2) Interest on the Notes began accruing on April 16, 2013. 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.

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

33

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

(5) 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 per MMBtu, estimated based on forward rates. Amounts are based on spot rates inclusive of estimated transportation costs and sales tax.

(6) 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 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.

(7) 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 September 30, 2013, we had no off-balance sheet arrangements aside from the operating leases described above under “Contractual Obligations” and bonding obligations described in the accompanying notes to the condensed consolidated financial statements.

Results of Operations for the Three Months Ended September 30, 2013, and 2012

Net Sales

Net sales of potash decreased $53.7 million, or 49%, from $110.4 million for the three months ended September 30, 2012, to $56.7 million for the three months ended September 30, 2013. This decrease was primarily the result of a 37% decrease in volume, in addition to a decrease in the average net realized sales price of potash by $81 per ton, or 18%. Our customers have delayed purchases of potash for the fall application season in response to continued downward pressure on potash prices driven by softness and uncertainty in the global potash market and, to a lesser extent, by the delayed fall application season compared with 2012, as discussed previously.

Net sales of Trio^® decreased from $9.2 million for the three months ended September 30, 2012, to $7.9 million for the three months ended September 30, 2013, due to a 19% decrease in the volume of sales partially offset by a 5% increase in the average net realized sales price. Demand for granular-sized and pelletized Trio^® continues to exceed production; however, demand for standard-sized Trio^® has been less predictable. Trio^® domestic pricing has historically tended to move in a relatively close correlation to potash pricing. However, over the last year, tight supply combined with dealers' and farmers' recognition of the benefits of this low chloride product, coupled with the added value of magnesium and sulfate from this specialty product, has translated into higher prices despite sequentially lower potash prices.

Our production volume of potash in the third quarter of 2013 was 167,000 tons, or 22,000 tons less than in the third quarter of 2012. As discussed previously, our production at our West facility was impacted by lower recoveries. In addition, we are currently mining some more complex ore zones at our East facility, which has impacted the quality of material delivered to the plant and reduced our potash production. Our langbeinite production increased 5,000 tons, or 14%, in the third 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 September 30,				Change Between
	2013		2012		Periods			% Change
Cost of goods sold (in millions)	$	46.8	$	63.4	$	(16.6	)	(26	)%
Cost per ton of potash sold(1)	$	253	$	224	$	29		13	%
Cost per ton of Trio® sold(2)	$	322	$	270	$	52		19	%

34

(1) Depreciation and depletion expense for potash was $8.4 million and $10.2 million in the third quarter of 2013 and 2012, respectively, which equates to $54 and $41 on a per ton basis.

(2) Depreciation and depletion expense for Trio^® was $1.4 million and $1.5 million in the third quarter of 2013 and 2012, respectively, which equates to $61 and $56 on a per ton basis.

Total cost of goods sold of potash, which includes royalties and depreciation, depletion and amortization, increased $29 per ton, or 13%, from $224 per ton for the three months ended September 30, 2012, to $253 per ton for the three months ended September 30, 2013. We experienced higher cash operating cost of goods sold per ton for the third quarter of 2013 largely due to increased production costs per ton at our East facility resulting from comparatively lower production volumes as we work through more complex ore zones. In addition, we recorded lower of cost or market adjustments of approximately $2.1 million on our remaining potash inventory at our East facility.

Total cost of goods sold of Trio^® increased $52 per ton, or 19%, from $270 per ton for the three months ended September 30, 2012, to $322 per ton for the three months ended September 30, 2013. During the third quarter of 2013, our production of langbeinite increased compared with the third quarter of 2012 as a result of our long-term improvement plan at our East facility, which we implemented in 2012. Our per-ton production costs increased in the third quarter of 2013 over those in the third quarter of 2012 due to the production challenges discussed previously.

In total, our cost of goods sold decreased $16.6 million, or 26%, from $63.4 million in the three months ended September 30, 2012, to $46.8 million in the three months ended September 30, 2013. This decrease was due to fewer tons of potash and Trio^® sold in the third quarter of 2013, partially offset by an increased inventory carrying value per ton due to increased maintenance, electricity and professional services associated with our production facilities.

On a comparative basis, and within our production costs, depreciation and depletion increased $3.1 million, or 28%, during the third quarter of 2013 as a result of the significant capital investments being put into service over the last year. We expect depreciation expense to continue to increase into the early part of 2014 on both an actual dollar basis and on a per-ton basis as we complete our major capital projects described previously. We manage capital investments on the basis of evaluating capital projects that we believe are necessary to maintain the productivity of our mines as well as evaluating investment capital that is designed to increase production and generate incremental returns on invested capital.

Other Operating Expense

In the third quarter of 2013, our application for certain New Mexico employment-related tax credits was denied. We believe the denial is improper and we intend to vigorously pursue recovery of these credits. Nonetheless, we recorded a reserve of approximately $2.8 million for credits relating to the denied periods.

Results of Operations for the Nine Months Ended September 30, 2013, and 2012

Net Sales

Net sales of potash decreased $85.1 million, or 29%, from $292.9 million for the nine months ended September 30, 2012, to $207.8 million for the nine months ended September 30, 2013. This decrease was the result of a 17% decrease in sales volumes of potash in addition to a decrease in the average net realized sales price of potash by $64 per ton, or 14%, in the comparable period. Our customers have delayed purchases of potash during the third quarter of 2013 given continued downward pressure on potash prices driven by softness and uncertainty in the global potash market, exacerbated by a delayed fall application season compared with 2012, as discussed previously.

Net sales of Trio^® increased from $26.2 million for the nine months ended September 30, 2012, to $34.1 million for the nine months ended September 30, 2013, due to a 17% increase in the volume of sales in addition to an 11% increase in the average net realized sales price of Trio^®. We continue to see strong demand for our Trio^® product, particularly the granular-sized and pelletized products. Trio^® domestic pricing has historically tended to move in a relatively close correlation to potash pricing, although, dealers' and farmers' recognition of the benefits of this low chloride product, coupled with the added value of magnesium and sulfate from this specialty product, has translated into higher prices despite sequentially lower potash prices.

Our production volume of potash in the first nine months of 2013 was 571,000 tons, or 7,000 tons less than in the first nine months of 2012. Our Trio^® production increased 38,000 tons, or 39%, in the first nine months of 2013 as we continue to progress with operating our langbeinite facility more effectively and efficiently.

Cost of Goods Sold

35

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

	Nine Months Ended September 30,				Change Between
	2013		2012		Periods			% Change
Cost of goods sold (in millions)	$	155.6	$	175.0	$	(19.4	)	(11	)%
Cost per ton of potash sold(1)	$	243	$	238	$	5		2	%
Cost per ton of Trio® sold(2)	$	266	$	283	$	(17	)	(6	)%

(1) Depreciation and depletion expense for potash was $26.0 million and $27.0 million in the first nine months of 2013 and 2012, respectively, which equates to $49 and $42 on a per ton basis.

(2) Depreciation and depletion expense for Trio^® was $5.2 million and $4.8 million in the first nine months of 2013 and 2012, respectively, which equates to $54 and $59 on a per ton basis.

Total cost of goods sold of potash, which includes royalties and depreciation, depletion and amortization, increased $5 per ton, or 2%, from $238 per ton for the nine months ended September 30, 2012, to $243 per ton for the nine months ended September 30, 2013. We experienced higher cash operating cost of goods sold per ton for the first nine months of 2013 due to increased production costs per ton at our East and West facilities resulting from comparatively lower production levels as we work through more complex ore zones at our East facility and our recovery improvement projects at our West facility, each discussed previously.

Total cost of goods sold of Trio^® decreased $17 per ton, or 6%, from $283 per ton for the nine months ended September 30, 2012, to $266 per ton for the nine months ended September 30, 2013. This decrease in cost of goods sold on a per-ton basis largely resulted from the higher Trio^® production volumes in the first nine months of 2013 over which production costs are allocated. As a result, our Trio^® per ton production costs decreased in the first nine months of 2013 over those in the first nine months of 2012.

In total, our cost of goods sold decreased $19.4 million, or 11%, from $175.0 million in the nine months ended September 30, 2012, to $155.6 million in the nine months ended September 30, 2013, as a result of fewer tons of potash sold in the first nine months of 2013. As a percentage of sales, cost of goods sold increased as a result of increases in labor costs, natural gas, electricity, maintenance and professional services during the nine months ended September 30, 2013, which increased the inventory carrying value per ton.

On a comparative basis, and within our production costs, depreciation and depletion increased $8.4 million, or 27%, during the first nine months of 2013 as a result of the significant capital investments being placed into service during the last year. We expect depreciation expense to continue to increase into the early part of 2014 on both an actual dollar basis and on a per-ton basis as we continue to invest capital into our operations and as some of our significant capital investments, described previously, are completed. 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 $1.1 million in the first nine months of 2013 compared with the first nine months of 2012. The change represents a 4% increase from $25.0 million for the nine months ended September 30, 2012, to $26.1 million for the nine months ended September 30, 2013. This increase was primarily due to higher labor and benefit costs in the first nine months of 2013 as we hired additional professional staff to support our level of process improvements and general administrative support.

Other Operating Expense

In the third quarter of 2013, we received notification that our application for certain New Mexico employment-related credits had been denied, as discussed previously. Although we plan to vigorously pursue all available means to recover these credits, we recorded a reserve of $2.8 million against previously filed claims in "Other expense" included in Operating income in the condensed consolidated statement of operations for the three months ended September 30, 2013.

In the second quarter of 2013, we received a refund from the State of New Mexico related to a compensating tax refund submitted in prior periods. The receipt of the refund removed uncertainty about the amount and collection of the refund, and therefore we recorded $1.7 million of income, which was also recorded in "Other expense" included in Operating income in the condensed consolidated statement of operations for the nine months ended September 30, 2013.

36

Other Income (Expense)

In April 2013, we funded $2.0 million to settle all pension plan liabilities and recorded an additional expense of approximately $1.9 million to reflect the termination of the pension plan. This amount is recorded as "Other income (expense)" in the condensed consolidated statements of operations for the nine months ended September 30, 2013, and represents the difference between the final amount funded, and the sum of the recorded pension liability and the unrecognized actuarial losses included in accumulated other comprehensive income.

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.

In July 2013, FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The new guidance prescribes the balance sheet presentation of unrecognized tax benefits relating to net operating loss carryforwards or similar items. ASU 2013-11 is effective for fiscal years beginning after December 15, 2013. Intrepid does not anticipate a material impact on its consolidated financial statements upon adoption.

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 September 30, 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.

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 September 30, 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 September 30, 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

37

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

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 financial condition, results of operations or cash flows. 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 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

None.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

None.

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 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.

• Section 104(b) Orders - These orders are issued for alleged failure to totally abate the subject matter of a Section 104(a) citation within the period specified in the citation.

• Section 104(d) Citations and Orders - These citations and orders are issued for an alleged unwarrantable failure (i.e., aggravated conduct constituting more than ordinary negligence) to comply with a mining safety standard or regulation.

• Section 110(b)(2) Violations - These violations are issued, and penalties are assessed, for flagrant violations (i.e., a reckless or repeated failure to make reasonable efforts to eliminate a known violation that substantially and proximately caused, or reasonably could have been expected to cause, death or serious bodily injury).

• Section 107(a) Orders - These orders are issued for an imminent danger to immediately remove miners.

• Total Dollar Value of MSHA Assessments Proposed - Proposed assessments issued during the period do not necessarily relate to the citations or orders issued by MSHA during that period or to the pending legal actions reported in the table.

• Notice of Pattern of Violations Under Section 104(e); Notice of Potential to Have Pattern under Section 104(e) - These notices are issued for a pattern of violation of mandatory health or safety standards or for the potential to have such a pattern.

• Legal Actions Pending, Initiated, and Resolved - The Federal Mine Safety and Health Review Commission (the “Commission”) is an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. Each legal action is assigned a docket number by the Commission and may have as its subject matter one or more citations, orders, penalties, or complaints.

The table below summarizes the types of legal actions that were pending as of September 30, 2013:

Mine Name and MSHA Identification Number	Contests of Citations and Orders	Contests of Proposed Penalties	Complaints for Compensation	Complaints of Discharge, Discrimination or Interference	Applications for Temporary Relief	Appeals of Judges' Decisions or Orders	Total
Intrepid Potash East (29-00170)	5	—	—	1	—	—	6
Intrepid Potash West (29-00175)	3	—	—	—	—	—	3
Intrepid Potash North (29-02028)	—	—	—	—	—	—	—
HB Potash (29-00173) (idled underground mine)	—	—	—	—	—	—	—

• Contests of Citations and Orders relate to challenges by operators, miners or miners' representatives to the issuance of a citation or order issued by MSHA.

• Contests of Proposed Penalties (Petitions for Assessment of Penalties) are administrative proceedings challenging a civil penalty that MSHA has proposed for the violation contained in a citation or order.

• Complaints for Compensation are filed by miners entitled to compensation when a mine is closed by certain withdrawal orders issued by MSHA for the purpose of determining the amount of compensation, if any, due miners idled by the orders.

• Complaints of Discharge, Discrimination or Interference involve a miner's allegation that he or she has suffered a wrong by the operator because he or she engaged in some type of activity protected under the Mine Act, such as making a safety complaint, or that he or she has suffered discrimination and lost his or her position.

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 or reclamation of mines.

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

	Three Months Ended September 30,					Nine Months Ended September 30,

The current portion of asset retirement obligations of $1.0 million and $1.2 million was included in "Other" current liabilities on the condensed consolidated balance sheets as of September 30, 2013, and December 31, 2012. The undiscounted amount of asset retirement obligation is $53.6 million as of September 30, 2013, of which Intrepid estimates approximately $8.8 million in payments may occur in the next five years.

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 and magnesium chloride.

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, including the brine injection system, and has placed potash-enriched brine into all of the newly constructed solar evaporation ponds. Intrepid expects to begin producing potash from the HB Solar Solution mine after the construction of the mill is completed in late 2013.

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 centrally 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.

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 September 30, 2013, the following awards were outstanding under the plan: 372,503 shares of non-vested restricted shares of common stock; 97,367 non-vested performance units representing shares of common stock; and options to purchase 338,744 shares of common stock. As of September 30, 2013, approximately 3.6 million shares of common stock remained 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 was $0.9 million and $0.6 million for the three months ended September 30, 2013, and 2012. Total compensation expense related to the non-vested restricted shares of common stock awards was $2.6 million and $2.5 million for the nine months ended September 30, 2013, and 2012. These amounts are net of estimated forfeiture adjustments. As of September 30, 2013, there was $5.9 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 nine months ended September 30, 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	235,490		$	19.25
Vested	(88,186	)	$	27.12
Forfeited	(15,558	)	$	22.16
Non-vested restricted shares of common stock, end of period	372,503		$	21.65

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 September 30, 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 September 30, 2013, and 2012, Intrepid recognized stock‑based compensation related to performance units of approximately $0.2 million and $0.1 million, respectively. For the nine months ended September 30, 2013, and 2012, Intrepid recognized stock‑based compensation related to performance units of approximately $0.5 million and $0.2 million, respectively. As of September 30, 2013, there was $0.7 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 September 30, 2013, and 2012, Intrepid recognized stock‑based compensation related to previously issued stock options of approximately $0.1 million and $0.3 million, respectively. For the nine months ended September 30, 2013, and 2012, Intrepid recognized stock‑based compensation related to previously issued stock options of approximately $0.5 million and $0.9 million, respectively. As of September 30, 2013, there was $0.2 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 September 30, 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	338,744	$26.25	$—	6.1	$13.13
Vested or expected to vest, end
of period	337,643	$26.22	$—	6.1	$13.11
Exercisable non-qualified
stock options, end of period	308,434	$25.33	$—	6.0	$12.50

(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.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

9 Months Ended

Sep. 30, 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, but are not limited to, those for proven and probable mineral reserves, the related present value of estimated future net cash flows, useful lives of plant assets, asset retirement obligations, normal inventory production levels, inventory valuations, the valuation of equity awards, the valuation of derivative financial instruments, the valuation of receivables, 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 experience 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 that have not 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 capitalized on 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 condensed 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 "Accumulated other comprehensive income" 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, short-term and long-term investments, restricted cash, accounts receivable, refundable income taxes, and accounts payable. These instruments are carried at cost, which approximates fair value due to the short-term maturities of the instruments. All available-for-sale investments are carried at fair value. Allowances for doubtful accounts are recorded against the accounts receivable balance to estimate net realizable value. The fair value of the long-term debt is estimated using discounted cash flow analysis based on current borrowing rates for debt with similar remaining maturities and ratings. Although there are no amounts currently outstanding under Intrepid’s unsecured credit facility, any borrowings that become outstanding would bear interest at a floating rate and therefore be recorded at their estimated fair value.

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.

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 Intrepid's consolidated financial position, results of operations, or cash flows.

In July 2013, FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The new guidance prescribes the balance sheet presentation of unrecognized tax benefits relating to net operating loss carryforwards or similar items. ASU 2013-11 is effective for fiscal years beginning after December 15, 2013. Intrepid does not anticipate a material impact on its consolidated financial statements upon adoption.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

9 Months Ended

Sep. 30, 2013

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, but are not limited to, those for proven and probable mineral reserves, the related present value of estimated future net cash flows, useful lives of plant assets, asset retirement obligations, normal inventory production levels, inventory valuations, the valuation of equity awards, the valuation of derivative financial instruments, the valuation of receivables, 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 experience 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 that have not 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 capitalized on 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 condensed 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 "Accumulated other comprehensive income" 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, short-term and long-term investments, restricted cash, accounts receivable, refundable income taxes, and accounts payable. These instruments are carried at cost, which approximates fair value due to the short-term maturities of the instruments. All available-for-sale investments are carried at fair value. Allowances for doubtful accounts are recorded against the accounts receivable balance to estimate net realizable value. The fair value of the long-term debt is estimated using discounted cash flow analysis based on current borrowing rates for debt with similar remaining maturities and ratings. Although there are no amounts currently outstanding under Intrepid’s unsecured credit facility, any borrowings that become outstanding would bear interest at a floating rate and therefore be recorded at their estimated fair value.

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.

Defined Benefit Pension Plan—In December 2011, Intrepid adopted resolutions to terminate the Moab Salt, L.L.C. Employees' Pension Plan, a defined benefit pension plan, which was acquired in conjunction with the purchase of its Moab assets in 2000. After receiving the necessary regulatory approvals, plan amendments, and participant settlement elections, Intrepid funded $2.0 million to settle all pension plan liabilities in April 2013. Upon funding, Intrepid was released from any further obligations under the pension plan. Accordingly, Intrepid recorded the additional expense of approximately $1.9 million to reflect the termination of the pension plan in the nine months ended September 30, 2013. This amount is recorded as "Other income (expense)" in the condensed consolidated statement of operations and represents 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. The components of the net periodic pension expense are set forth below (in thousands):

The fair values of Intrepid's investments in corporate bonds are below their respective costs due to recent increases in short-term interest rates. However, Intrepid considers the unrealized losses on these investments to be temporary given Intrepid's current plans to hold the investments. These investments have been classified as available-for-sale. For the three and nine months ended September 30, 2013, Intrepid's available-for-sale investments had gross realized gains of approximately $12,000 and $48,000, respectively. For the three and nine months ended September 30, 2013, Intrepid recognized gross realized losses of zero and approximately $19,000, respectively, on investments classified as available-for-sale. For the three and nine months ended September 30, 2012, no investments were classified as available-for-sale.

Debt Disclosure [Abstract]

DEBT

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. The facility was amended in August 2013 to extend the maturity date by two years to August 2018, to decrease the applicable interest rates on any borrowings, to decrease the quarterly commitment fees, and to increase the maximum allowable leverage ratio to 3.5. The minimum allowable fixed charge coverage ratio under the facility remains at 1.3.

Under the facility, the leverage ratio is defined as the ratio of total funded indebtedness to adjusted EBITDA (earnings before interest, income taxes, depreciation, amortization, and certain other expenses) for the prior four fiscal quarters. The fixed charge coverage ratio is defined as the ratio of adjusted EBITDA for the prior four fiscal quarters to fixed charges. Both ratios may operate to limit the total amount available to Intrepid under the facility.

The facility is unsecured and is guaranteed by Intrepid's material subsidiaries. There were no amounts outstanding under the facility, and the full amount of the facility was available to Intrepid, as of September 30, 2013, and December 31, 2012.

Unsecured Senior Notes—In April 2013, Intrepid issued $150 million aggregate principal amount of unsecured senior notes ("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 is paid semiannually on April 16 and October 16 of each year, beginning on October 16, 2013. Interest expense is recorded net of any capitalized interest associated with investments in capital projects. Intrepid incurred gross interest expense for the three months ended September 30, 2013, and 2012, of $1.7 million and $0.2 million, respectively. Intrepid incurred gross interest expense for the nine months ended September 30, 2013, and 2012, of $3.3 million and $0.7 million, respectively. Intrepid capitalized $1.4 million and $2.6 million of interest during the three and nine months ended September 30, 2013. Intrepid had no capitalized interest in 2012.

EARNINGS PER SHARE

Dilutive securities, including stock options, non-vested restricted stock and performance units, are excluded from the diluted weighted average shares outstanding computation in periods in which they have an anti-dilutive effect, such as when there is a net loss. 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 September 30, 2013, and 2012, a weighted average of 277,284 and 123,237 non-vested shares of restricted common stock and 342,495 and 197,896 stock options, respectively, were anti-dilutive and therefore were not included in the diluted weighted average share calculation. For the nine months ended September 30, 2013, and 2012, a weighted average of 171,058 and 114,285 non-vested shares of restricted common stock and 310,471 and 191,299 stock options, respectively, were anti-dilutive and therefore were not included in the diluted weighted average share calculation.

INCOME TAXES

Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

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 effect of the depletion and domestic production activities deduction and research and development credits. Intrepid’s effective tax rate for the nine months ended September 30, 2013, and 2012 was 35.4% and 32.8%, respectively. Intrepid believes the effective tax rate for the nine months ended September 30, 2013, is more meaningful than the effective rate for the three months ended September 30, 2013. During the three months ended September 30, 2013,  the estimated depletion and domestic production activities deductions had a more pronounced impact on the effective rate due to the normal recurring update to Intrepid’s estimated before tax income amount for the 2013 calendar year.

A summary of the provision for income taxes is as follows (in thousands):

	Three Months Ended September 30,					Nine Months Ended September 30,
	2013			2012		2013			2012
Current portion of income tax (benefit) expense	$	(1,123	)	$	3,576	$	(780	)	$	7,260
Deferred portion of income tax expense	773			7,109		16,299			28,350
Total income tax (benefit) expense	$	(350	)	$	10,685	$	15,519		$	35,610

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. As a result, Intrepid recorded additional deferred state income tax expense of $1.3 million in the second quarter of 2013, as its deferred tax asset had decreased in value. 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.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE

Assets Measured at Fair Value—Fair value accounting establishes a fair value hierarchy that prioritizes the inputs to the valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

• 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.

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 September 30, 2013, and December 31, 2012 (in thousands):

			Fair Value at Reporting Date Using
	September 30, 2013		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	$	68,199	$	—	$	68,199	$	—

			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 on the 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 used are appropriate and consistent with the requirements of ASC Topic 820 and the methods used by 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.

Financial Instruments—The carrying values and fair values of our financial instruments as of September 30, 2013, and December 31, 2012, are as follows (in thousands):

	September 30, 2013				December 31, 2012
	Carrying Value		Fair Value		Carrying Value		Fair Value
Cash and cash equivalents	$	10,446	$	10,446	$	33,619	$	33,619
Certificate of deposits	$	2,260	$	2,260	$	6,666	$	6,666
Accounts receivable	$	33,762	$	33,762	$	40,630	$	40,630
Refundable income taxes	$	4,505	$	4,505	$	3,306	$	3,306
Accounts payable	$	22,094	$	22,094	$	19,634	$	19,634
Long-term debt	$	150,000	$	142,341	$	—	$	—

For cash and cash equivalents, certificate of deposit investments, accounts receivable, refundable income taxes, and accounts payable, the carrying amount approximates fair value because of the short-term maturity of those instruments. The fair value of the long-term debt is estimated using discounted cash flow analysis based on current borrowing rates for debt with similar remaining maturities and ratings (a Level 2 input) and is designed to approximate the amount at which the instruments could be exchanged in an arm's length transaction between knowledgeable willing parties.

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.

New Mexico Employment Credits—Since September 2011, Intrepid has recorded, and continues to record, the value of estimated refundable employment-related credits for qualified wages paid in New Mexico. Intrepid began recognizing these credits in the financial statements at the point in time that previous tax credit filings had been approved and paid by the State of New Mexico, thereby confirming that the criteria for recognition was deemed probable and reasonably estimable. Since that time, the estimated recoverable value of these credits has been, and continues to be, reflected as a reduction to our production costs and amounts yet to be collected are recorded in “Other receivables, net” in the condensed consolidated balance sheets in the same period in which the credit is earned.

In the third quarter of 2013, the New Mexico Taxation and Revenue Department denied Intrepid's application to receive the New Mexico High Wage Jobs Credit for certain prior years' filings.  Intrepid believes the denial is improper and intends to vigorously pursue recovery of these credits.  Nonetheless, Intrepid has recorded a reserve of approximately $2.8 million for credits relating to the denied periods in order to reflect the denial of the claimed credits.  As the inventory associated with the denied credits for periods prior to 2012 has since been sold, Intrepid recorded the expense associated with recording the reserve as an "Other expense" in Operating income in the condensed consolidated statement of operations for the three months ended September 30, 2013. The value of credits associated with 2012 and 2013 have been established as a net receivable as of September 30, 2013, and is reflected in "Other receivables, net" in the condensed consolidated balance sheets.

Legal—Intrepid is subject to litigation. Intrepid has determined that there are no material claims outstanding as of September 30, 2013. Intrepid has established a legal reserve for loss contingencies that are considered probable and reasonably estimable.

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

DERIVATIVE FINANCIAL INSTRUMENTS

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 September 30, 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.

Intrepid did not have any derivative instruments outstanding during the first nine months of 2013.
