Notes to Consolidated Financial Statements

(Unaudited)

NOTE 1

GENERAL

In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary to fairly present the financial position of Stillwater Mining Company (the “Company”) at June 30, 2016, and the results of its operations for the three and six months ended June 30, 2016 and 2015, respectively and cash flows for the six months ended June 30, 2016 and 2015, respectively. The results of operations for the first six months of 2016 are not necessarily indicative of the results to be expected for the 2016 year. The accompanying consolidated financial statements in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's 2015 Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 22, 2016 (Form 10-K). All inter-company transactions and balances have been eliminated in consolidation.

The preparation of the Company’s consolidated financial statements in conformity with United States generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes. The more significant areas requiring the use of management’s estimates relate to mineral reserves, reclamation and environmental obligations, valuation allowance for deferred tax assets, useful lives utilized for depreciation, amortization and accretion calculations, future cash flows from long-lived assets, and fair value of derivatives and other financial instruments. Actual results could differ from these estimates.

On May 28, 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue it expects to be entitled to for the transfer of promised goods or services to customers. In August 2015, the FASB issued ASU 2015-14, Deferral of the Effective Date, which defers the effective date of ASU 2014-09 by one year to January 1, 2018. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP. The standard permits the use of either the retrospective or cumulative effect transition method. The Company continues to evaluate the effect that ASU 2014-09 will have on its consolidated financial statements and disclosures and has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. Early adoption is not permitted.

On April 7, 2015, as part of its initiative to simplify and reduce complexity in financial statements, the FASB issued ASU 2015-03, Interest - Imputation, (Subtopic 835-30): Simplifying the Presentation of Debt Issuance. This ASU requires the debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. Also, it requires retrospective application for all prior periods presented in the financial statements and a disclosure of the nature of and reason for the change in accounting principle, the transition method, a description of the prior-period information that has been retrospectively adjusted and the effect of the change on the financial statement line items. ASU 2015-03 is effective for financial statements issued for fiscal years beginning after December 31, 2015, and interim periods within those fiscal years. Early adoption was permitted for financial statements that had not been previously issued. The Company elected early adoption of ASU 2015-03 and reclassified Deferred debt issue costs against the related liability for all periods presented. Prior to the adoption of ASU 2015-03, the balance reported at December 31, 2015 for total Long-term debt and capital lease obligations was $258.9 million, and after adoption and reclassification of Deferred debt issue costs of $3.8 million, the total balance reported at December 31, 2015 became $255.1 million.

On July 22, 2015, as part of its initiative to simplify and reduce complexity in financial statements, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. ASU 2015-11, which will change the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. ASU 2015-11 is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company is evaluating the effect that ASU 2015-11 will have on its consolidated financial statements and disclosures and has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. The ASU requires prospective adoption and permits early adoption.

On February 25, 2016, the FASB issued ASU 2016-02, Leases, (Topic 840), which requires an entity that leases assets, with terms of more than 12 months, to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. ASU 2016-02 is effective for financial statements issued for fiscal years beginning after December 31, 2018, and interim periods within those fiscal years. The Company is evaluating the effect that ASU 2016-02 will have on its consolidated financial statements and disclosures and has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. Early adoption is permitted.

On March 30, 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employees Shared-Based Payment Accounting. The ASU will change several aspects within share based payments: (1) accounting for income taxes, (2) classification of excess tax benefits, (3) forfeitures, (4) minimum statutory tax withholding requirements, (5) classification of employee taxes paid when an employer withholds shares for tax-withholding purposes, (6) practical expedient - expected term, (7) intrinsic value, and (8) eliminating the indefinite deferral. ASU 2016-09 is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company is evaluating the effect that ASU 2016-09 will have on its consolidated financial statements and disclosures and has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. Early adoption is permitted in any interim or annual period provided that the entire ASU is adopted.

NOTE 2

SALES

MINE PRODUCTION

The Company mines and processes ores containing palladium, platinum, rhodium, gold, silver, copper and nickel into intermediate and final products for sale to customers. Palladium, platinum, rhodium, gold and silver are sent to a third-party refiner for final processing from which they are sold to customers with whom the Company has established trading relationships. Refined platinum group metals (PGMs) in sponge form are transferred upon sale from the Company’s account at the third-party refiner to the account of the purchaser. By-product metals are normally sold at market price to customers, brokers or outside refiners. Copper and nickel by-products are typically sold at a discount to the quoted market prices. By-product sales (gold, nickel, mined rhodium, copper and silver) are included in revenues from Mine Production. During each of the three months ended June 30, 2016 and 2015, total by-product sales totaled $6.1 million and $6.9 million, respectively. For the six months ended June 30, 2016 and 2015, by-product sales totaled $11.3 million and $13.7 million, respectively.

In July 2014, the Company executed five-year supply and refining agreements with Johnson Matthey (JM). Under the terms of these agreements, JM has an exclusive five-year right to refine all of the PGM filter cake the Company produces at its Columbus, Montana facilities. JM also has the right to purchase all of the Company's mine production of palladium and platinum at competitive market prices (except for platinum sales under the Company's sales agreement with Tiffany & Co., which are specifically excluded from the JM agreements) and has the right to bid for any recycling volumes the Company has available. Other provisions of the agreements include a good-faith effort by JM to assist in growing the Company's recycling volumes and the sharing of market intelligence to the extent permitted by law. The Company has the right to exit the JM PGM supply arrangement in return for the payment of a nominal fee. In addition, the Company, in its sole discretion, may elect to terminate the refining arrangement after July 2018.

In accordance with the terms of the JM PGM supply agreement, all Company sales of mined PGMs, other than the platinum sales under the Company's sales agreement with Tiffany & Co., were to JM for the six months ended June 30, 2016 and 2015.

PGM RECYCLING

The Company purchases spent catalyst materials from third-parties for recycling and processes these materials within its facilities in Columbus, Montana to recover palladium, platinum and rhodium for sale. The Company has entered into sourcing arrangements for catalyst materials with various suppliers. Under these sourcing arrangements the Company may advance cash as general working capital or against a shipment of material shortly before actually receiving the physical shipment at the Company's processing facilities. These advances are included in Other current assets on the Company’s Consolidated Balance Sheets until such time as the materials have been physically received and title has transferred to the Company, at which time the advance is reclassified into Inventories. Finance charges collected on advances and inventories prior to being earned are included in Other current liabilities on the Company’s Consolidated Balance Sheets. Finance charges are reclassified from Other current liabilities to Interest income ratably from the time the cash advance was made until the out-turn date of the inventory from the final refiner.

The Company also accepts material supplied from third-parties on a tolling basis, processing it for a fee and returning the recovered metals to the supplier.

TOTAL SALES

Total sales to significant customers as a percentage of total revenues for the three and six months ended June 30, 2016 and 2015 were as follows:



	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2016		2015 ⁽¹⁾		2016 ⁽¹⁾		2015 ⁽¹⁾
Customer A	72	%	80	%	76	%	77	%
Customer B	10	%	—		—		—

(1) The “—” symbol represents less than 10% of total revenues.

NOTE 3

ASSET IMPAIRMENT

In accordance with the FASB Accounting Standards Codification 360, Property Plant and Equipment, (ASC 360-10), the Company reviews and evaluates its long-lived assets for impairment when events and changes in circumstances indicate that the related carrying amounts of such assets may not be recoverable and may exceed their fair value. For purposes of determining impairment, assets are grouped at the lowest level for which identifiable cash flows (including estimated future cash flows from non-operating properties) are largely independent of the cash flows of other groups of assets and liabilities.

The Company determined there were no material events or circumstances requiring the Company to test long-lived assets for impairment at June 30, 2016. However, during the second quarter of 2015, the Company concluded that there was evidence to suggest that there had been a significant decrease in the fair value of the Marathon mineral properties. Accordingly, the Company performed an analysis that indicated the carrying value of the Marathon mineral properties exceeded its recoverable amount at June 30, 2015. The Company undertook an assessment of the fair value of its Marathon mineral properties, which included the examination of recent comparable transactions. At June 30, 2015, the Company recorded an impairment charge of $46.8 million (before-tax) against the carrying value of the Marathon mineral properties in Canada, reducing its carrying value to an estimated fair value of $8.6 million.

NOTE 4

NONCONTROLLING INTEREST

In the fourth quarter of 2015, the Company purchased a 25% interest held by Mitsubishi Corporation (Mitsubishi) in Stillwater Canada Inc (SCI), the Company's subsidiary, which holds the Marathon PGM-copper assets. The Company paid total cash consideration of $5.2 million which equaled $1.0 million in cash and 25% of the total cash and cash equivalents held by SCI.

Prior to the repurchase, Mitsubishi's 25% interest in SCI's net loss for each period was shown as Net loss attributable to noncontrolling interest in the Company's Consolidated Statements of Comprehensive Income (Loss). The amount of the loss was added back to the Company's reported Net (loss) income in each period in arriving at Net (loss) income attributable to common stockholders. The reported Net loss attributable to noncontrolling interest for the three and six months ended June 30, 2015 was $11.5 million and $11.7 million, respectively.

NOTE 5

DERIVATIVE INSTRUMENTS

The Company uses various derivative financial instruments to manage its exposure to changes in PGM market commodity prices.

COMMODITY DERIVATIVES

PGM Recycling

The Company customarily enters into fixed forward sales contracts relating to PGM recycling of catalyst and other industrial sourced materials. Under these fixed forward transactions, the Company agrees to deliver a stated quantity of metal on a specific future date at a price stipulated in advance. The Company uses fixed forward transactions to set in advance the pricing for metals acquired and processed in its recycling segment. The metals from PGM recycled materials are sold forward at the time of purchase and delivered against the fixed forward contracts when the ounces are recovered. Because this forward price is also used to set the acquisition price the Company pays for recycling materials, this arrangement significantly reduces exposure to PGM price volatility. The Company believes such transactions qualify for the exception to hedge accounting treatment and has elected to account for these transactions as normal purchases and normal sales.

All of the Company's fixed forward sales contracts open at June 30, 2016, will settle at various periods through December 2016. The Company has credit agreements with its major trading partners that provide for margin deposits in the event that forward prices for metals exceed the Company’s hedged prices by a predetermined margin limit. At June 30, 2016, and December 31, 2015, no margin deposits were outstanding or due.

The following is a summary of the Company's outstanding commodity derivatives in its Recycling Business Segment at June 30, 2016:



PGM Recycling:
Fixed Forward Contracts	Platinum			Palladium			Rhodium
Settlement Period	Ounces	Average Price/Ounce		Ounces	Average Price/Ounce		Ounces	Average Price/Ounce

NOTE 6

SHARE COMPENSATION PLANS

EQUITY PLANS

The Company sponsors equity plans (the Plans) that enable the Company to grant equity-based compensation to employees and non-employee directors. The Company currently issues restricted stock units as incentive compensation under the Plans. In total, approximately 11.6 million shares of common stock have been authorized for issuance under the Plans, including approximately 5.0 million, 5.2 million, and 1.4 million authorized shares under the 2012 Equity Incentive Plan, 2004 Equity Incentive Plan and the General Employee Plan, respectively. Approximately 4.1 million shares were available and reserved for issuance under the 2012 Equity Incentive Plan at June 30, 2016.

The Compensation Committee of the Company's Board of Directors administers the Plans and determines the type of equity awards to be issued, the exercise period, vesting period and all other terms of instruments issued under the Plans.

NONVESTED SHARES

Time-Based Restricted Stock Unit Awards

Time-based restricted stock unit awards provide the participant with the right to receive a number of shares of the Company's common stock upon vesting of the awards provided the participant is employed by the Company on the vesting date. Time-based awards are valued using the Company's common stock price on the date of grant.

Time-based awards are not entitled to any dividend equivalents with respect to the restricted stock units unless otherwise determined by the Board, nor any dividends on stock that may be delivered in settlement of the restricted stock units unless and until the stock is issued in settlement of the restricted stock units.

Nonvested time-based share activity during the six months ended June 30, 2016, is detailed in the following table:



	Nonvested Shares		Weighted-Average Grant-Date Fair Value

Total compensation expense, included within General and administrative in the Company's Consolidated Statements of Comprehensive Income (Loss) related to grants of time-based nonvested shares was $0.6 million and $0.4 million, in the three months ended June 30, 2016 and 2015 respectively, and $1.0 million and $0.8 million, respectively, for the six months ended June 30, 2016 and 2015.

Performance-Based Restricted Stock Unit Awards

The Company grants performance-based restricted stock unit awards under its Long Term Incentive Plan (LTIP). The payout of the awards is dependent upon distinct components with separate sub-targets. The sub-targets are either market-based or performance-based and classified as either equity or liability. The market-based sub-targets are valued using a Monte Carlo simulation valuation model on the date of grant. The fair value of the liability-classified sub-targets are re-measured each reporting period. The existence of a market condition requires recognition of compensation cost for the performance restricted stock unit awards over the requisite period regardless of whether the market condition is satisfied. Total compensation expense, included within General and administrative in the Company's Consolidated Statements of Comprehensive Income (Loss), related to grants of performance-based restricted stock unit awards for the three months ended June 30, 2016 and 2015 was $0.5 million and $0.4 million, respectively and $0.9 million and $0.6 million, respectively, for each of the six months ended June 30, 2016 and 2015.

A performance-based restricted stock unit award provides the participant with the right to receive a number of shares of the Company's common stock depending on achievement of specific measurable performance criteria. The number of shares earned is determined at the end of each performance period, generally three years, based on the actual performance criteria predetermined by the Compensation Committee at the time of grant. In the period when it becomes probable that the performance criteria will be achieved, the Company recognizes expense for the proportionate share of the total fair value of the grant related to the vesting period that has already lapsed. The remaining cost of the grant is expensed over the balance of the vesting period. For awards that contain performance-based conditions, and for which the Company determines it is no longer probable that it will achieve the minimum performance criteria specified in the Plan, the Company reverses all of the previously recognized compensation expense in the period when such a determination is made.

Performance-based restricted stock unit awards are not entitled to any dividend equivalents with respect to the restricted stock units unless otherwise determined by the Board, nor any dividends on stock that may be delivered in settlement of the restricted stock units unless and until the stock is issued in settlement of the restricted stock units.

Share activity under nonvested performance-based restricted stock unit awards activity during the first six months of 2016 is detailed in the following table:

NOTE 7

INCOME TAXES

The Company determines income taxes using the asset and liability method, which results in the recognition of deferred tax assets and liabilities. These assets and liabilities reflect the expected future tax consequences of temporary differences between the carrying amount and the tax basis of those assets and liabilities, as well as operating loss and tax credit carryforwards, using enacted tax rates in effect in the years in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets and liabilities are recorded on a jurisdictional basis.

In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. The Company has a valuation allowance in 2016 and 2015 to reflect the estimated amount of deferred tax assets which may not be realized, which principally relate to foreign and state net operating losses, capital losses, and certain tax credits.

The benefit for income taxes for the three and six months ended June 30, 2016 is related to the carryback of the current year losses and the deferred tax benefits from certain foreign jurisdictions, offset by an increase in the provision for uncertain tax positions in the U.S. Changes in the Company’s net deferred tax assets and liabilities have been partially offset by a corresponding change in the valuation allowance.

The Company recognized an income tax benefit for the three months ended June 30, 2016 of $0.2 million and an income tax provision of $0.4 million, for the three months ended June 30, 2015. The Company recognized an income tax benefit for the six months ended June 30, 2016 and 2015, of $0.8 million and $5.7 million, respectively. The current year losses, partially offset by the discrete charge of $3.4 million for an increase in the provision for uncertain tax positions, are primarily responsible for the tax benefit for the six months ended June 30, 2016. The partial restructure of internal operations and the creation of a separate metal sales and trading subsidiary was responsible for $8.6 million of the total $9.7 million discrete income tax benefit recognized for the six months ended June 30, 2015.

The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in Income tax benefit (provision) in the Company's Consolidated Statements of Comprehensive Income (Loss). The Company had uncertain benefits of $3.4 million at June 30, 2016. Interest and penalties of $0.1 million have been accrued at June 30, 2016. The Company anticipates there could be a change in uncertain tax positions during the next twelve months. The Company made income tax payments of $0.3 million and $11.1 million in the six months ended June 30, 2016 and 2015, respectively. Tax years still open for examination by the taxing authorities are the years ended December 31, 2015, 2014, 2013, 2012 and 2011, although net operating loss and credit carryforwards from all years are subject to examination and adjustment for the three years following the year in which the carryforwards are utilized.

NOTE 8

DEBT AND CAPITAL LEASE OBLIGATIONS

1.75% CONVERTIBLE DEBENTURES

In October 2012, the Company issued $396.75 million aggregate principal amount of 1.75% senior unsecured convertible debentures due October 15, 2032 (1.75% debentures). Each $1,000 principal amount of these 1.75% debentures is initially convertible, under certain circumstances and during certain periods, into 60.4961 shares (subject to customary anti-dilution adjustments) of the Company's common stock, which represents an initial conversion price of $16.53 per share. The 1.75% debentures also include an embedded conversion enhancement feature that is equivalent to including each debenture with a warrant initially exercisable for 30.2481 shares at an exercise price of $16.53 per share (also subject to customary anti-dilution adjustments). The Company, at its election, may settle conversions of the 1.75% debentures in cash, shares of its common stock or any combination of cash and shares of its common stock.

Holders have the right to redeem their 1.75% debentures at face value, plus accrued and unpaid interest, on October 15th, of each of 2019, 2024, 2029, and upon the occurrence of certain corporate events. The Company will have the right to call the 1.75% debentures at any time on or after October 20, 2019.

The 1.75% debentures were bifurcated under GAAP into separate debt and equity components, and reflect an effective maturity (to the first optional redemption date) of seven years. The residual amount of $141.6 million recorded in equity is treated for accounting purposes as additional debt discount and accreted as an additional non-cash interest charge to earnings over the expected life. Debt and equity issuance costs totaling approximately $12.4 million were deducted from the gross proceeds of the offering of the 1.75% debentures, and the debt portion is being amortized ratably over seven years.

In the third quarter of 2015, the Company repurchased $61.6 million of outstanding principal under the 1.75% debentures, paying cash of $59.4 million. The Company reduced the debt component by $50.7 million, which included a reduction of the debt discount by $10.9 million. The difference between the book value and the fair value (including $0.7 million of debt and equity issuance costs) of the debt component resulted in a $4.2 million loss.

The 1.75% debentures have an effective interest rate of 8.50% and a stated interest rate of 1.75%, with interest paid semi-annually. The balance outstanding at June 30, 2016 was approximately $263.8 million, which is net of unamortized discount of $68.0 million and $3.4 million deferred debt issue costs. The balance outstanding at December 31, 2015 was $254.6 million, which was net of unamortized discount of $76.8 million and $3.8 million of deferred debt issue costs.

1.875% CONVERTIBLE DEBENTURES

Holders of the remaining $0.5 million of outstanding 1.875% debentures may require the Company to redeem their 1.875% debentures at face value on March 15, 2018 or March 15, 2023, or at any time before March 15, 2028 upon the occurrence of certain events including a change in control. Effective March 22, 2013, the Company has the right at its discretion to redeem the remaining $0.5 million of outstanding 1.875% debentures for cash at any time prior to maturity. In the third quarter of 2015, the Company repurchased $1.7 million of the outstanding principal of the 1.875% debentures, paying cash of $1.6 million and recording a gain of approximately $0.1 million. The outstanding balance at June 30, 2016 and December 31, 2015, of $0.5 million aggregate principal amount, is reported as a long-term debt obligation.

ASSET-BACKED REVOLVING CREDIT FACILITY

In December 2011, the Company signed a $100.0 million asset-backed revolving credit agreement incurring debt issuance costs of $1.1 million. In January 2012, the Company completed the syndication of this facility and simultaneously expanded its maximum line of credit to $125.0 million, incurring additional debt issuance costs of $0.2 million. The Company also paid an unused line fee on the committed but unutilized balance under the facility at a rate per annum of 0.375% or 0.5%, depending on utilization of the facility.

The Company terminated this credit facility on December 31, 2015, incurring expenses and fees of approximately $0.2 million.

The following table reflects the amortization of debt issuance costs, interest expense and cash payments on the Company's outstanding debt for the three and six months ended June 30, 2016 and 2015:

For the three months ended June 30, 2016 and 2015, the Company capitalized interest of $2.0 million and $1.4 million, respectively. For the six months ended June 30, 2016 and 2015, the Company capitalized interest of $3.9 million and $2.7 million, respectively. Capitalized interest is recorded as a reduction to Interest expense in the Company's Consolidated Statements of Comprehensive Income (Loss).

SEGMENT INFORMATION

The Company operates five reportable business segments: Mine Production, PGM Recycling, Canadian Properties, South American Properties and All Other. These segments are managed separately based on fundamental differences in their operations and geographic separation.

The Mine Production segment consists of two business components: the Stillwater Mine and the East Boulder Mine. The Mine Production segment is engaged in the development, extraction, processing and refining of PGMs. The Company has agreements in place to sell its PGMs from mine production. The financial results for the Stillwater Mine and the East Boulder Mine have been aggregated, as both have similar products, processes, customers, distribution methods and economic characteristics.

The PGM Recycling segment is engaged in the recycling of spent catalyst materials to recover the PGMs contained in the materials. The Company purchases catalyst materials processed by the PGM Recycling segment from third-party suppliers for its own account and sells the recovered metals directly, and it also accepts catalyst materials from third-parties on a tolling basis, processing it for a fee and returning the recovered metals to the supplier. The Company allocates costs of the Company's smelting and base metal refining facilities to both the Mine Production segment and to the PGM Recycling segment for internal and segment reporting purposes because these facilities support the PGM extraction requirements of both business segments.

The Canadian Properties segment consists of the Marathon mineral property assets. The exploration-stage Marathon mineral properties include a large PGM and copper deposit located near the town of Marathon, Ontario, Canada as well as additional mineral properties located adjacent to the Marathon properties.

The South American Properties segment consists of the Peregrine Metals Ltd. assets. The principal Peregrine property is the Altar property, an exploration-stage copper-gold resource located in the San Juan province of Argentina.

The All Other group primarily consists of assets, including cash and cash equivalents, investments, revenues, and expenses of various corporate and support functions.

The Company evaluates performance and allocates resources based on income or loss before income taxes.

INVESTMENTS

The Company classifies the marketable securities in which it invests as available-for-sale securities. These securities are measured at fair value in the financial statements with unrealized gains or losses recorded in Other comprehensive income in the Company's Consolidated Statements of Comprehensive Income (Loss). At the time the securities are sold or otherwise disposed of, gross realized gains and losses are included in Net income (loss) Gross realized gains and losses are based on the carrying value (cost, net of discounts or premiums) of the sold investment. The amounts reclassified out of Other comprehensive income during the three and six months ended June 30, 2016 and 2015 were insignificant.

The amortized cost, gross unrealized gains, gross unrealized losses, and fair value of available-for-sale investment securities by major security type and class of security at June 30, 2016 and December 31, 2015 were as follows:

The Company carries items in its inventories at the lower of cost or market value. If the market value in any period falls below the carrying value, the carrying value of the inventory item is reduced to its market value.

For purposes of inventory accounting, the market value of inventory is generally deemed equal to the Company’s current cost of replacing the inventory, provided that: (1) the market value of the inventory may not exceed the estimated selling price of such inventory in the ordinary course of business less reasonably predictable costs of completion and disposal, and (2) the market value may not be less than net realizable value reduced by an allowance for a normal profit margin. No reduction to inventory value was necessary in the first six months of 2016 or 2015.

The costs of PGM mined inventories as of any date are determined based on combined production costs per ounce and include all inventoriable production costs, including direct labor, direct materials, depletion, depreciation and amortization and other overhead costs relating to mining and processing activities incurred as of such date. Costs are aggregated and averaged for mined material carried in inventory.

The costs of PGM recycling inventories as of any date are determined based on the acquisition cost of the recycled material and include all inventoriable processing costs, including direct labor, direct materials, depreciation and third-party refining costs which relate to the processing activities incurred as of such date. Costs incurred are allocated and tracked separately for each specific lot of recycling material (including material tolled on behalf of others).

NOTE 14

EARNINGS PER SHARE

Basic earnings per share attributable to common stockholders is computed by dividing net earnings available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share attributable to common stockholders reflects the potential dilution that could occur if the Company’s dilutive outstanding stock options or nonvested shares were exercised or vested, the contingently issuable shares were issued and the Company’s convertible debt was converted. The Company currently has only one class of shares of capital stock outstanding.

No adjustment was made to reported net loss attributable to common stockholders when calculating diluted loss per share attributable to common stockholders for the three months ended June 30, 2015 and for the six months ended June 30, 2016 and 2015 because the Company reported a consolidated net loss attributable to common stockholders and inclusion of these shares would have been anti-dilutive. Potential dilutive common shares include those associated with outstanding stock options, restricted stock units, performance shares and convertible debentures.

The following table shows the reconciliation of the computation of basic and diluted shares and the related impact on income for the three months ended June 30, 2016:

NOTE 15

FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants. A three-level fair value hierarchy prioritizes the inputs used to measure fair value. This hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The classification of each financial asset or liability within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels of inputs used to measure fair value are as follows:


•	Level 1 - Quoted prices in active markets for identical assets or liabilities.


•	Level 2 - Observable inputs other than quoted prices included in Level 1 such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or inputs that are observable or can be corroborated by observable market data.


•	Level 3 - Unobservable inputs supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Financial assets and liabilities measured at fair value on a recurring basis at June 30, 2016 and December 31, 2015, consisted of the following:

The money market funds are recorded in Cash and cash equivalents on the Company's Consolidated Balance Sheets. The fair value of the mutual funds is based on market prices that are readily available and are recorded in Other noncurrent assets on the Company's Consolidated Balance Sheets. The fair value of the investments is valued indirectly using observable data, quoted prices for similar assets or liabilities in active markets. Unrealized gains or losses on mutual funds and investments are recorded in Accumulated other comprehensive income (loss) on the Company's Consolidated Balance Sheets.

ITEM 2

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

The commentary that follows should be read in conjunction with the consolidated financial statements and notes thereto included in this Quarterly Report on Form 10-Q and with the information provided in the Company's 2015 Annual Report on Form 10-K, filed with the Securities and Exchange Commission on February 22, 2016 (Form 10-K).

OVERVIEW

Stillwater Mining Company (the Company) is a Delaware corporation that has its shares of common stock listed on the New York Stock Exchange under the symbol "SWC". The Company extracts and processes ores containing palladium and platinum (along with by-product metals) from two underground mines situated within the J-M Reef, a geological formation of platinum group metal (PGM) mineralization, which is located in Stillwater and Sweet Grass Counties in south-central Montana. Ore produced from the mines is crushed and concentrated in mills located at each mine site. Mine concentrates are then trucked to the Company’s processing complex in Columbus, Montana, where they are smelted and partially refined. In addition to the mine concentrates, the Company also recycles spent automotive catalyst and other materials containing PGMs it receives from third parties at the processing complex. A portion of this recycling activity is material the Company purchases for its own account; while the remainder is toll processed on behalf of others for a fee. After being processed through the Company's processing facilities in Columbus, the final product, a PGM-rich filter cake, is shipped to Johnson Matthey (JM) in New Jersey for final refining before it is then delivered as finished metal.

SECOND QUARTER 2016 SUMMARY RESULTS

For the second quarter of 2016, the Company reported a consolidated net income attributable to common stockholders of $0.8 million, or $0.01 per diluted share, as compared to the consolidated net loss attributable to common stockholders of $27.5 million, or $0.23 per diluted share, for the second quarter of 2015. The lower operating results in the second quarter of 2016 were driven by a significant reduction in average combined realized price per mined ounce, which fell from $842 per ounce in the second quarter of 2015 to $665 per ounce in the second quarter of 2016, which was offset, in part, by a reduction in unit costs. The second quarter of 2015 included an impairment charge of $46.8 million (before-tax).

Segment earnings from the Company's mining operations totaled $10.3 million (before income taxes) for the second quarter of 2016, compared to $21.4 million (before income taxes) for the same period in 2015. Volumes of mined palladium and platinum sold in the second quarter of 2016 increased to 150,900 ounces from 133,000 ounces in the second quarter of 2015, reflecting both increased production and draw-down of mine ounce inventory. The average combined realized price per ounce on sales of mined palladium and platinum in the second quarter of 2016 was 21.0% lower than that realized in the second quarter of 2015.

Costs of metals sold per PGM mined ounce is the Company's most directly comparable GAAP financial measure to total cash costs, net of credits, per PGM mined ounce, a non-GAAP financial measure. The Company's consolidated costs of metals sold per mined ounce of palladium and platinum was $501 per ounce in the second quarter of 2016 as compared to $606 per ounce in the second quarter of 2015, a 17.3% decrease. Consolidated total cash costs, net of credits, per PGM mined ounce for the Company's mining operations averaged $420 per ounce in the second quarter of 2016, which was 20.8% lower than the $530 per ounce in the second quarter of 2015, mostly resulting from higher production rates at the East Boulder Mine, labor reductions at the Stillwater Mine and a number of cost improvement initiatives at both mines. (See "Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures").

Segment earnings from the Company's recycling activities (before income taxes) were $3.0 million in the second quarter of 2016, an increase over the $2.0 million in the second quarter of 2015. Earnings in the recycling segment typically lag corresponding volumes processed by approximately two to three months. Total recycling ounces of palladium, platinum and rhodium fed to the smelter, including both purchased ounces and ounces processed on a toll basis, increased 12.1% to 169,900 ounces in the second quarter of 2016 from 151,600 ounces in the second quarter of 2015. Recycling volumes sold increased 25.3% during the second quarter of 2016 totaling 85,300 ounces (including palladium, platinum and rhodium) at an average realization of $666 per ounce, as compared to 68,100 ounces sold during the second quarter of 2015 at an average realization of $954 per ounce. The Company delivered 70,700 recycled tolled ounces during the second quarter of 2016, up from 37,400 recycled tolled ounces delivered in the second quarter of 2015, an 89.0% increase.

The Company's cash and cash equivalents balance was $130.1 million at June 30, 2016, as compared to $147.3 million at December 31, 2015. Total outstanding liquidity, which includes highly liquid investments as well as available cash and cash equivalents, was $442.2 million at June 30, 2016, as compared to $463.8 million at December 31, 2015. See "Note 12 - Investments", in the notes to the consolidated financial statements for more information related to the Company's investments. Net working capital (including cash and cash equivalents and highly liquid investments) decreased to $519.2 million at June 30, 2016, from $523.0 million at December 31, 2015. Working capital associated with the recycling activities was $63.1 million at June 30, 2016 compared to $37.4 million at December 31, 2015.

MINING OPERATIONS

Mine production of palladium and platinum totaled 137,100 ounces for the second quarter of 2016, an increase of 8.0% from the 127,000 ounces produced in the second quarter of 2015.

Costs of metals sold per PGM mined ounce is the Company's most directly comparable GAAP financial measure to total cash costs, net of credits, per PGM mined ounce, and All-in Sustaining Costs (AISC) per PGM mined ounce, both non-GAAP financial measures. The Company's consolidated costs of metals sold per mined ounce of palladium and platinum was $501 per ounce in the second quarter of 2016 as compared to $606 per ounce in the second quarter of 2015, a 17.3% decrease. The measurement of total cash costs per PGM mined ounce includes the benefit of credits for by-product sales and PGM Recycling segment income (before income taxes). The table below illustrates the effect of applying these credits to the average cash costs per PGM mined ounce for the combined Montana mining operations. Total cash costs per PGM mined ounce were reduced by 14.4% as a result of reduced labor costs which were offset by an 8.0% increase in production in the second quarter of 2016 when compared to second quarter of 2015.

* These are non-GAAP financial measures. For a full description and reconciliation of these and other non-GAAP financial measures to GAAP financial measures, see Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures below.

The Company utilizes AISC (non-GAAP financial measure) to assess the overall operating efficiency of the Company's Montana operations. This metric is an indication of the total cash capital and operating costs per PGM mined ounce (including corporate general and administrative costs) required to sustain the Company's current level of mining activities. For the second quarter of 2016, AISC averaged $594 per PGM mined ounce, a 3.1% decrease from the first quarter of 2016, and 24.3% lower than the AISC of $785 per PGM mined ounce achieved in the second quarter of 2015. This was driven by lower total cash costs and lower capital spending incurred to sustain operations and higher production volumes during the second quarter of 2016. For a more complete discussion of this measure, refer to -- "Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures."

Stillwater Mine

At the Stillwater Mine, combined palladium and platinum production increased 8.2% in the second quarter of 2016 to 83,100 ounces, compared to 76,800 ounces produced in the second quarter of 2015. Ore grade averaged approximately 0.47 combined ounces of palladium and platinum per ton in the quarter ended June 30, 2016, as compared to 0.45 ounces per ton in the quarter ended June 30, 2015. Mined ore and sub-grade volumes fed to the Stillwater Mine concentrator during the second quarter of 2016 totaled 188,500 tons, an increase of 1.8% from the 185,100 tons fed in the same quarter of 2015.

Costs of metals sold per PGM mined ounce is Stillwater Mine's most directly comparable GAAP financial measure to total cash costs, net of credits, per PGM mined ounce, a non-GAAP financial measure. Costs of metals sold per mined ounce of palladium and platinum was $478 per ounce in the second quarter of 2016 as compared to $590 per ounce in the second quarter of 2015. Total cash costs per PGM mined ounce, net of credits, decreased by 26.0% in the second quarter of 2016 compared with the same period in 2015. The lower costs for the second quarter of 2016 are principally the result of a reduced labor force at the Stillwater Mine, higher production volumes, improved mining practices and the implementation of various cost reduction initiatives.

The following table illustrates the effect of applying the by-product and PGM Recycling segment credits to the total cash costs per PGM mined ounce at the Stillwater Mine:



	Three Months Ended				Six Months Ended
	June 30,				June 30,
Stillwater Mine	2016		2015		2016		2015
Costs of metals sold per PGM mined ounce	$	478	$	590	$	483	$	578

Total cash costs per PGM mined ounce, before by-product and recycling credits*	$	466	$	612	$	478	$	602
Less: By-product revenue credit per mined ounce	40		49		36		47

Total cash costs per PGM mined ounce, net of by-product and recycling credits*	$	405	$	547	$	425	$	539

Capital expenditures at the Stillwater Mine totaled $22.1 million for the second quarter of 2016, including $12.0 million for Blitz development. This compares to the $22.5 million of capital expenditures at the Stillwater Mine during the second quarter of 2015, of which $5.4 million was for Blitz development. The reduction in capital expenditures was primarily due to lower infrastructure activity in the mine along with higher development productivity that reduced unit rates. Primary and secondary development footages (excluding Blitz development) for the second quarter of 2016 decreased relative to the comparable footages for the second quarter of 2015, with primary and secondary development together advancing approximately 8,000 feet in the second quarter of 2016 and 10,900 feet in the second quarter of 2015. This was slightly above the development rates envisioned in the mine plan implemented in August 2015. Diamond drilling footage (excluding Blitz development) decreased for the second quarter of 2016, totaling approximately 50,700 feet, compared to 84,300 feet drilled in the second quarter of 2015. Ongoing mine development efforts, including diamond drilling, are part of a continuing effort to maintain the developed state of the mine.

East Boulder Mine

Mine production at the East Boulder Mine was 54,000 combined ounces of palladium and platinum for the second quarter of 2016, an increase of 7.6% from 50,200 ounces produced in the second quarter of 2015. Ore grade averaged approximately 0.37 combined ounces of palladium and platinum per ton in the quarter ended June 30, 2016, as compared to 0.39 ounces per ton in the quarter ended June 30, 2015. Mined ore and sub-grade volumes fed to the East Boulder Mine concentrator during the second quarter of 2016 increased 14.8% to 162,200 tons from 141,300 tons in the second quarter of 2015. This increase is due to additional plant run days and a higher feed rate to accommodate the increased mine production more than offsetting the slightly lower grade year on year.

Costs of metals sold per PGM mined ounce is East Boulder Mine's most directly comparable GAAP financial measure to total cash costs, net of credits, per PGM mined ounce, a non-GAAP financial measure. Costs of metals sold per mined ounce of palladium and platinum was $538 per ounce in the second quarter of 2016 as compared to $634 per ounce in the second quarter of 2015. Total cash costs per PGM mined ounce, net of credits, for the second quarter of 2016 decreased approximately 11.9% from the same period in 2015. The improvement in cash costs per ounce reflects the increased mine output and continuing cost reduction and productivity improvement initiatives.

The following table illustrates the effect of applying the by-product and PGM Recycling segment credits to the total cash costs per PGM mined ounce at the East Boulder Mine:



	Three Months Ended				Six Months Ended
	June 30,				June 30,
East Boulder Mine	2016		2015		2016		2015

Total cash costs per PGM mined ounce, net of by-product and recycling credits*	$	444	$	504	$	445	$	525

Capital expenditures at the East Boulder Mine totaled $3.2 million in the second quarter of 2016, as compared to $4.6 million in the second quarter of 2015. Actual primary and secondary development advanced approximately 5,700 feet during the second quarter of 2016 while the comparable development advance in the second quarter of 2015 was also 5,700 feet. Diamond drilling footage for the second quarter of 2016 totaled approximately 37,800 feet compared to the 105,900 feet drilled in the second quarter of 2015 when there was a campaign on drilling at Graham Creek to prepare for the development of the second ore block.

PGM RECYCLING SEGMENT

The volume of recycling materials processed through the smelter during the second quarter of 2016 was 26.4 tons per day of furnace feed compared to 26.9 tons per day in the second quarter of 2015. PGM loadings in the fed material in the second quarter of 2016 increased 12.1% to 169,900 ounces of palladium, platinum and rhodium compared to 151,600 ounces in the second quarter of 2015.

PGM tolled ounces returned	70,700	37,400	146,600	77,600

During the second quarter of 2016, the Company earned $3.0 million in income (before income taxes) from its PGM Recycling operations on revenues of $59.2 million. For the second quarter of 2015, the recycling operations earned $2.0 million in income (before income taxes) on revenues of $66.3 million.

For the second quarter of 2016, PGM Recycling revenues decreased by 10.7% compared to the same period in 2015 due to lower realized selling prices as a result of the fall in palladium and platinum market prices, which was partially offset by an increase in ounces sold. The cost of metals sold from the PGM Recycling segment was $56.5 million in the second quarter of 2016, as compared to $64.4 million in the second quarter of 2015, a decrease of 12.3%. A majority of the cost of metals sold from recycling in each period is attributable to the acquisition cost of purchasing recyclable materials for the Company's own account; therefore, the aggregate cost of metals sold from the PGM Recycling segment is driven mostly by the volume and the value of the PGMs in the materials purchased by the Company. Tolling revenues increased by approximately 80.0% in the second quarter of 2016 to $1.8 million, as compared to approximately $1.0 million in the second quarter of 2015, reflecting the increase in tolled ounces returned.

Sold ounces of recycled PGMs increased by 25.3% to 85,300 ounces in the second quarter of 2016 from 68,100 ounces in the second quarter of 2015. The combined average recycling sales realization (including palladium, platinum and rhodium) was $666 per sold ounce in the second quarter of 2016, down from $954 per sold ounce in the same quarter of 2015. In addition, the Company delivered 70,700 recycled tolled ounces during the second quarter of 2016, an increase of 89.0% from 37,400 recycled tolled ounces delivered in the second quarter of 2015. A total of 156,000 combined ounces were delivered to customers in the second quarter of 2016, as compared to 105,500 ounces delivered in the second quarter of 2015.

For its PGM Recycling segment, the Company customarily enters into fixed forward sales contracts that set the selling price for most of the PGMs recovered from recycled materials. Because the selling price of recycling materials held by the Company is fixed up front by these forward sales contracts, day-to-day changes in the market price of palladium and platinum have little effect on the percentage margins earned from processing these materials or on cash flow from recycling operations. However, as PGM prices rise or fall over time, the total volume of materials available in the market may also rise or fall and the selling price of recycling materials in the forward sales contracts may also change, which can affect the total profitability of the Company's recycling activities. On average, it takes two to three months from the date of receipt to process and deliver metal from purchased lots of recycling materials.

The Company has arrangements in place with many of its recycling suppliers to provide advance payments to the suppliers prior to the release of finished metal from the final refiner. These advances may include general working capital advances, advances against materials in transit to the Company's processing facilities, and payments for materials in process. Outstanding advances for general working capital and materials in transit not backed up by inventory physically in the Company’s possession totaled $7.8 million at June 30, 2016, as compared to $4.4 million at December 31, 2015. In addition, recycling segment materials physically in inventory totaled $55.3 million at June 30, 2016, as compared to $33.0 million at December 31, 2015. Working capital associated with the recycling activities was $63.1 million and $37.4 million at June 30, 2016 and December 31, 2015, respectively.

EXPLORATION AND DEVELOPMENT

The Company is continuing to develop the Blitz area, which is expected to provide extensive new mining infrastructure along the J-M Reef. This development includes constructing underground and surface access to an area extending approximately 23,000 feet to the east from the existing Stillwater Mine operations on two separate levels. The lower of these underground development headings, on the 50 East, is being driven with a tunnel-boring machine (TBM) and to date has advanced approximately 10,700 feet.

A second, parallel underground heading at Blitz, the 56 East, is being driven approximately 600 feet above the TBM using conventional drill and blast methods. Approximately 18,900 feet of ramp and infrastructure development has been completed along the 56 East heading to date. Development continues ahead of schedule along this heading and has not been delayed by unfavorable ground conditions. In the 50 East TBM drive, water inflows have been higher than anticipated which has slowed advance rates. A dewatering program is being instituted to enable a higher rate of advance to be achieved. The TBM drive is not on the critical path for first production or ramp up and efforts are being directed to the 56 East drive and the Benbow decline which are on the critical path for the project.

Combined primary Blitz development footages for the second quarter of 2016 increased relative to the comparable footages for the second quarter of 2015, advancing approximately 3,000 feet in the second quarter of 2016 and 2,000 feet in the second quarter of 2015. Diamond drilling footage for Blitz development increased for the second quarter of 2016, totaling approximately 36,000 feet, as compared to 12,400 feet drilled in the second quarter of 2015.

The permitting process for the Benbow access portal was completed in the third quarter of 2015. The Benbow access portal to be developed at the far end of the two primary Blitz tunnels, is designed to intersect the two tunnels from the surface, and will provide ventilation and emergency egress for the Blitz development area. The construction of the surface facilities is nearing completion.

The Blitz development began in late 2010, and to date, the Company has spent approximately $91.7 million (net of capitalized interest and capitalized depreciation) of an estimated $205 million of capital expenditures for the development. The Company has focused on accelerating the Blitz development timeline to enable the Company to bring forward plans for first production, now anticipated to occur in late 2017 or early 2018 with estimated costs to first production in the range of $155 million to $175 million. The Company anticipates the Blitz area will provide growth in the Company’s production profile and the Company's lowest cost mined ounces due to expected grade and as a result of the newly constructed infrastructure. The Blitz development is intended to contribute to the growth of Stillwater's annual palladium and platinum production over the first 10 years of production, after which the Company expects to use it to off-set the depletion of the Stillwater Mine's existing ore reserves.

While a modest exploration program continues at the Marathon project in Canada, development plans remain suspended until the project can demonstrate an economic return greater than the returns available on the Company's other assets.

Cash carrying costs at the Altar project in Argentina totaled approximately $1.2 million in the second quarter of 2016, consisting of administrative costs of $0.3 million and exploration expense of approximately $0.9 million. For the second quarter of 2015, cash carrying costs totaled $0.6 million, consisting of $0.1 million administrative costs and approximately $0.5 million of exploration expense.

CAPITAL EXPENDITURES

The Company incurred cash capital expenditures of $19.6 million during the second quarter of 2016 compared to cash capital expenditures of $30.3 million in the second quarter of 2015.

SUPPLY AND DEMAND COMMENTARY FOR PGM MARKETS

The following discussion reflects management’s assessment of the recent state of the PGM markets, based on discussions with industry analysts and the Company’s own observations of market dynamics. There can be no assurance that the Company’s conclusions reflect a complete or accurate picture of supply and demand trends or other market considerations. However, management’s view of market conditions and the outlook for PGM supply and demand may influence its decisions on mining activities, future acquisitions, expansions or divestitures, capital investment, financing, hiring and various other factors.

The primary suppliers of PGMs worldwide are limited to a few large producers in South Africa and Zimbabwe, significant PGM by-product output from Norilsk Nickel in Russia, plus output from the Company’s operations in Montana and a few (mostly by-product producers) in Canada.

Johnson Matthey (JM) estimated that 79% of palladium demand and 40% of platinum demand will come from the automotive catalyst market in 2016 (net of investment supply and demand), a percentage that has steadily grown over recent years for both metals. During the first half of 2016, the automotive market was strong across all major regions.

Both the U.S. and European car markets remained strong during the first half of 2016. U.S. auto sales through June 2016 were up 1.5% to 8.65 million units from the same period in 2015 according to Autodata Corp. Automobile sales in Europe through June 2016 were also up 9.1% to 8.09 million units from the same period in 2015 according to the European Automobile Manufacturers Association.

Total vehicle sales in China rose by 8.1% to 12.8 million units in the first half of 2016 compared with the same period in 2015, according to the China Association of Automobile Manufacturers. Vehicle sales were boosted by strong demand for sport utility vehicles and continued stimulus measures.

During the first half of 2016, the price for platinum reversed its previous downward trend, finishing the quarter at $999 per ounce. In prior years, South African producers increased supply into the market by destocking their inventories. In 2016, JM forecasts that the impact to supply will decline as the South African producers have less ability to continue to destock inventories. The South African rand depreciation in 2015 protected producers from the full brunt of last year’s decline in U.S. dollar denominated PGM prices. Through June 2016, the rand has strengthened removing a portion of the protection created from the previous year.

The price of palladium increased 3.5% over the second quarter of 2016 to close at $589 on June 30, 2016. After hitting a low of $470 per ounce in January 2016, the price of palladium recovered 25.3% at the end of June 2016. The overall market fundamentals for palladium continue to be strong. The use of palladium in the automotive, industrial and jewelry industries is expected to rise from 8.6 million ounces in 2010 to 10.1 million ounces in 2016 according to JM. Since 2012, this has significantly outpaced the level of supply from producers and recycles sources.

PALLADIUM and PLATINUM MARKET PRICE HISTORY

Annual world-wide palladium and platinum supply is driven by a combination of current mine production, recycling and draw-down of existing palladium and platinum inventories held by governments and financial investors. The prices of these metals are volatile and are affected by numerous factors including, but not limited to, the sale or purchase of the metals by various central banks and financial institutions, inflation, recession, fluctuation in the relative values of the U.S. dollar and foreign currencies (particularly the South African rand and Russian ruble), changes in global and regional demand and political and economic conditions throughout the world. The price of palladium is thought to be more closely tied to industrial demand and the rate of underlying world economic growth, particularly in automotive production.

STRATEGIC CONSIDERATIONS

The following discussion of corporate strategic efforts is intended to update matters discussed in previous filings. For a discussion of the Company's strategic decisions regarding exploration and development and capital expenditures, see the previous sections of this Item 2 entitled Exploration and Development and Capital Expenditures.

The Company's safety performance is of paramount importance to every employee of the Company and is the Company's primary consideration in all aspects of its operations. The Company normally assesses its safety performance using two broad sets of measures - incidence rates and regulatory compliance. Incidence rates in the U.S. usually are measured as the number of medically reportable events per 200,000 man hours. Regulatory compliance is measured in terms of the number and severity of citations issued to the Company and its contractors on site by Mine Safety and Health Administration (MSHA) inspectors.

The Company’s overall incidence rate per 200,000 man hours in its Montana operations for the first six months of 2016 was 2.36. This represents a 32.8% improvement in the incidence rate compared to the same period in 2015. For further detail, see Exhibit 95 - Mine Safety Disclosures, which is included as an exhibit to this filing.

The Company continues to focus on environmental excellence and works closely with governmental agencies and the local communities to ensure its compliance with environmental regulations and address its neighbors' environmental concerns. Based on the success of the installed underdrain system at the East Boulder Mine, the Company has commenced work on the installation of an underdrain system within the waste rock storage area at the Stillwater Mine. The purpose of this underdrain system is to capture and treat meteorological water that is currently infiltrating through the embankment and increasing the nitrate levels observed in the adjacent groundwater. The elevated groundwater nitrate levels are the result of explosives residue containing nitrogen, within the waste rock from the mines, which is being solubilized and mobilized via the meteorological water. As part of the effort to reduce the groundwater nitrate levels and due to lower solubility levels, the Company switched its blasting agent from ammonium nitrate-fuel oil (ANFO) to stick powder, at substantial additional consumable costs, when the conditions were initially observed. Following installation of this underdrain system, it is anticipated that the Stillwater Mine

will switch back to ANFO as its primary blasting agent later this year, at a substantial consumable cost savings. Based on previous experience from the East Boulder mining operations, the Company believes, there is potential for further improvements in productivity based on the use of ANFO explosives.

During the second quarter of 2016, the Company completed, along with the regulatory agencies, a joint review of the reclamation and closure bond for the Stillwater Mine. As a result of this review, the closure bond for the Stillwater Mine increased from $19.5 million to $22.0 million. The updated bond amount accounts for further operational development through the year 2020.

Cost containment remains a key focus throughout the Company's operations. Costs of metals sold per PGM mined ounce is the Company's most directly comparable GAAP financial measure to AISC, a non-GAAP financial measure, of overall cost efficiency of the Company's Montana operations. (See the later section of this Item 2 entitled All-in Sustaining Costs (A Non-GAAP Financial Measure) for a more detailed explanation of AISC). For the three months ended June 30, 2016, the Company's AISC averaged $594 per PGM mined ounce, a 3.1% decrease from the first quarter of 2016, and 24.3% lower than the AISC of $785 per PGM mined ounce achieved in the second quarter of 2015.

The Company's total workforce at June 30, 2016, was comprised of 1,426 employees, including 1,417 employees in Montana and Colorado; and nine employees in the Canada and South America. This compares to 1,600 employees at June 30, 2015, of which 1,591 were located in Montana and Colorado; and nine were in Canada and South America.

The Company seeks to maintain significant balance-sheet liquidity in order to manage against cyclical price risk in the mining industry and against downturns in the broader economy. When combining highly-liquid investments with cash and cash equivalents, the Company's liquidity at June 30, 2016 and December 31, 2015 totaled $442.2 million and $463.8 million, respectively. See "Note 12 - Investments", in the notes to the consolidated financial statements for more information related to the Company's investments. Total principal outstanding (before discounts and deferred debt issuance costs) under the Company's long-term convertible debt obligations at June 30, 2016 and December 31, 2015 totaled $335.7 million.

The Company continues to evaluate options to maximize stockholder value and the long-term health of its business, particularly in light of volatility in commodity prices. The Company regularly considers the deployment of cash for acquisitions, internal growth projects, dividends, buyback of outstanding convertible debentures and share repurchases.

The Company currently has available excess capacity in its mine concentrators and in its Columbus processing facilities. The Company has been exploring various opportunities to increase throughput at its processing facilities, primarily through growing its recycling business segment and potentially through other processing arrangements with third parties. The auto catalyst recycling business is very competitive and, following the significant increase in volumes fed in 2015, attaining further significant growth while maintaining margins may prove to be challenging.

RESULTS OF OPERATIONS

Comparison of Three Months Ended June 30, 2016 and 2015

The Company’s total revenues decreased by 10.6% to $165.7 million in the second quarter of 2016 compared to $185.4 million for the second quarter of 2015. The following analysis provides comparative detail for key factors contributing to the decrease in revenues:

(1)	Ounces sold and average realized price per ounce from PGM Recycling relate to ounces produced from processing of spent catalyst from catalytic converters and other industrial sources.


(2)	By-product metals sold reflect net values of realized prices (discounted due to product form) per unit sold.


(3)	The Company’s average realized price represents revenues, which include the effect of hedging gains and losses realized on commodity instruments and agreement discounts, divided by ounces sold. The average market price represents the average London market for the actual months of the period.


(4)	The Company reports a combined average realized and market price of palladium and platinum at the same ratio as ounces that are produced from the base metal refinery.

Net revenues from sales of Mine Production (including proceeds from the sale of by-products) were $106.4 million and $119.0 million during the second quarters of 2016 and 2015, respectively. The higher volumes of mined ounces sold in the second quarter of 2016 as compared to the second quarter of 2015 were not sufficient to offset the significant reduction in average combined realized price per mined ounce in the second quarter of 2016, as compared to the second quarter of 2015.

The costs of metals sold from Mine Production totaled $75.6 million for the second quarter of 2016, compared to $80.6 million for the second quarter of 2015, a decrease of 6.2%. The decrease in costs is the result of higher production rates at the East Boulder Mine, labor reductions at the Stillwater Mine and a number of cost improvement initiatives at both mines.

Total recycling ounces of palladium, platinum and rhodium fed to the smelter, including both purchased ounces and ounces processed on a toll basis, increased to 169,900 ounces in the second quarter of 2016 from 151,600 ounces in the second quarter of 2015, an increase of 12.1%. Total sales revenues from PGM Recycling of $59.2 million in the second quarter of 2016 were down 10.7% from the $66.3 million reported for the second quarter of 2015. Tolling revenues in the second quarter of 2016 rose to $1.8 million on 70,700 tolled ounces of palladium, platinum and rhodium processed and returned to customers, compared to $1.0 million on 37,400 ounces processed and returned to customers in the second quarter of 2015. However, revenues from sales of purchased recycling materials declined 13.0% in the second quarter of 2016 to $56.9 million on 85,300 ounces of palladium, platinum and rhodium sold, from $65.4 million on 68,100 ounces sold in the second quarter of 2015. The Company’s combined average realization on recycling sales of palladium, platinum and rhodium decreased to $666 per ounce in the second quarter of 2016, compared to $954 per ounce realized in the second quarter of 2015.

The costs of metals sold from PGM Recycling totaled $56.5 million in the second quarter of 2016, compared to $64.4 million in the second quarter of 2015, a decrease of 12.3%. This decrease was mainly due to the decrease in the total cost of acquiring recycling material for processing as well as lower volumes of purchased recycled material.

The mining operations PGM ounce production for the second quarters of 2016 and 2015 is shown in the following table:

The Company's corporate general and administrative costs for the second quarters of 2016 and 2015 were $8.3 million and $10.4 million, respectively.

Total interest income for the second quarters of 2016 and 2015 was $1.0 million and $0.7 million, respectively. Interest expense in the second quarters of 2016 and 2015 was $4.1 million and $5.3 million, respectively, net of capitalized interest of $2.0 million and $1.4 million, respectively.

Comparison of Six Month Periods Ended June 30, 2016 and 2015

The Company’s total revenues decreased by 22.4% to $299.3 million in the first six months of 2016 compared to $385.9 million in the first six months of 2015. The following analysis covers key factors contributing to the decrease in revenues:

For the first six months of 2016, net revenues from sales of Mine Production (including proceeds from the sale of by-products) totaled $192.2 million, a decrease of 21.5% compared to $244.7 million in the first six months of 2015. The higher volumes of mined ounces sold in the first six months of 2016 was not enough to offset the significantly lower realized PGM prices in the first six months of 2016 as compared to the first six months of 2015.

The cost of metals sold from Mine Production totaled $143.0 million in the first six months of 2016, compared to $160.7 million in the first six months of 2015, a decrease of 11.0%. The decrease in costs is the result of higher production rates at the East Boulder Mine, labor reductions at the Stillwater Mine and a number of cost improvement initiatives at both mines. Royalties and severance taxes were also lower as a result of the significantly lower metals prices.

Revenues from PGM Recycling reflected a decrease of 24.2% during the first six months of 2016, to $106.9 million from $141.0 million in the first six months of 2015. Recycling ounces sold during the first six months of 2016 totaled 148,700 ounces, an increase of 4.2% compared to the 142,700 ounces sold in the first six months of 2015. The Company’s combined average realization on recycling sales (which include palladium, platinum and rhodium) decreased to $681 per ounce in the first six months of 2016 from $968 per ounce in the first six months of 2015. The decrease in recycling earnings during the first six months of 2016 is attributable to several factors, including a weak market due to lower commodity prices and offset by the draw-down of inventories contributing to the increase in ounces sold.

Overall, recycling costs of metals sold decreased by 25.2% to $102.5 million in the first six months of 2016 from $137.1 million in the first six months of 2015, mostly as the result of lower PGM prices.

During the first six months of 2016, the Company’s mining operations produced 274,400 ounces of PGMs, compared to 260,300 ounces in 2015 as shown in the following table:

General and administrative costs decreased to $16.6 million in the first six months of 2016, from $18.7 million in the first six months of 2015, a decrease of approximately 11.2%. The Company recognized $4.4 million in exploration expenses primarily related to its mineral properties in Canada and South America in the first six months of 2016, compared to $1.8 million in the first six months of 2015.

During the first six months of 2016, the Company recorded a net foreign currency transaction gain of $1.2 million, compared to a net gain of $0.1 million in the first six months of 2015. Essentially all of these net gains related to the re-measurement into U.S. dollars of the deferred taxes recorded in association with the acquisition of Peregrine Metals Ltd. During 2016, the rate of Argentine peso inflation has declined significantly, reducing the Company's currency gains. The gain in 2015 was a result of the strength of the U.S. dollar relative to a rapidly depreciating Argentine peso. The gains reflect the impact of a high inflation rate in Argentina as the deferred tax obligation is remeasured from Argentine pesos into U.S. dollars.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities (which includes changes in working capital) was $16.9 million and $59.6 million for the six months ended June 30, 2016 and 2015, respectively. The Company’s net cash flow from operating activities is affected by several key factors, including net realized prices for its products, the level of PGM production from its mines, cash operating costs, the volume of activity in its PGM Recycling segment, changes in inventory balances and the timing of cash receipts from final customers. Mining productivity rates and ore grades affect both PGM production and cash costs of production. The reported net cash provided by operating activities for the first six months of 2016 reflected primarily lower realized PGM prices from mining activity along with higher recycling working capital balances, which was partially offset by higher recycling earnings and lower cash costs.

Changes in the cash costs and revenues per ounce of Mine Production generally flow through dollar-for-dollar into cash flow from operations. Using metals market prices at June 30, 2016, a 10% reduction in annual PGM mined production would reduce annual cash flow from operations by an estimated $20.6 million.

Net cash used in investing activities for the six months ended June 30, 2016, was approximately $33.4 million, comprised of $4.0 million of net proceeds from maturities and sales of short-term investments offset by $38.4 million of cash capital expenditures and approximately $1.0 million in proceeds from the sale of long-term investments and the disposal of property, plant and equipment. For the six months ended June 30, 2015, net cash used in investing activities was $116.0 million, comprised of $58.2 million of cash capital expenditures and approximately $57.8 million of net purchases of short-term investments.

Net cash used in financing activities in the six months ended June 30, 2016 was $0.7 million, comprised of principal payments on capital leases. For the six months ended June 30, 2015, the net cash associated with financing activities was $1.0 million, comprised of principal payments on the capital leases.

At June 30, 2016, the Company’s cash and cash equivalents balance was $130.1 million, compared to $147.3 million at December 31, 2015. When combining highly liquid investments with available cash and cash equivalents, the Company’s balance sheet liquidity was $442.2 million at June 30, 2016 compared to $463.8 million at December 31, 2015. See "Note 12 - Investments", in the notes to the consolidated financial statements for more information related to the Company's investments. Net working capital (including cash and cash equivalents and highly liquid investments) was $519.2 million at June 30, 2016 compared to $523.0 million at December 31, 2015.

Outstanding balance sheet debt (current and long-term) reported at June 30, 2016, was approximately $264.3 million, up from the $255.8 million at December 31, 2015. The Company’s total principal debt includes approximately $263.8 million of 1.75% convertible debentures and $0.5 million of 1.875% convertible debentures. The $263.8 million of 1.75% convertible debentures represents the net discounted value of the 1.75% notes, first redeemable in 2019, valued against a borrowing rate of 8.5%, as the gross principal amount originally borrowed was $396.75 million. The total gross principal outstanding (before discounts and debt issuance costs) under the Company's long-term convertible debt obligations was $335.7 million at June 30, 2016.

The Company expects to make cash payments of $2.9 million for interest during the remaining six months of 2016 related to its outstanding debt obligations. The Company made cash payments for interest of $2.9 million for the six months ended June 30, 2016, as compared to $3.6 million for the same period of 2015.

CONTRACTUAL OBLIGATIONS

The Company's contractual obligations at December 31, 2015, are summarized in Item 7, "Management's Discussion and Analysis - Contractual Obligations" of the Company's Form 10-K, which was filed with the Securities and Exchange Commission on February 22, 2016. In the first six months of 2016, there were no material changes in the Company's contractual obligations outside the ordinary course of business.

Sub-grade tons milled includes reef waste material only. Reef waste material is PGM-bearing mined material below the cutoff grade for proven and probable reserves but with sufficient economic value to justify processing it through the concentrator along with the mined ore. Total tons milled includes ore tons and sub-grade tons only. See “Proven and Probable Ore Reserves – Discussion” in the Company’s Form 10-K for further information.

(2)

Total cash costs include total operating costs plus royalties, insurance and taxes other than income taxes. Total cash costs per PGM mined ounce, net of credits, is a non-GAAP financial measure that management uses to monitor and evaluate the efficiency of its mining operations. This measure of cost is not defined under U.S. Generally Accepted Accounting Principles (GAAP). Please see “Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures” and the accompanying discussion for additional detail.

RECONCILIATION OF GAAP FINANCIAL MEASURES TO NON-GAAP FINANCIAL MEASURES

The Company utilizes certain non-GAAP financial measures as indicators in assessing the performance of its mining and processing operations during any period. Because of the processing time required to complete the extraction of finished PGM products, there are typically lags of one to three months between ore production and sale of the finished product. Revenues in any period include some portion of material mined and processed from prior periods as the revenue recognition process is completed. Consequently, while costs of revenues (a GAAP measure included in the Company’s Consolidated Statements of Comprehensive Income (Loss)) appropriately reflects the expense associated with the materials sold in any period, the Company has developed certain non-GAAP financial measures to assess the costs associated with its producing and processing activities in a particular period and to compare those costs between periods.

While the Company believes that these non-GAAP financial measures may also be of value to outside readers, both as general indicators of the Company’s mining efficiency from period to period and as insight into how the Company internally measures its operating performance, these non-GAAP financial measures are not standardized across the mining industry and in most cases will not be directly comparable to similar measures that may be provided by other companies. These non-GAAP financial measures are only useful as indicators of relative operational performance in any period, and because they do not take into account the inventory timing differences that are included in costs of revenues, they cannot meaningfully be used to develop measures of earnings or profitability. A reconciliation of these measures to costs of revenues, the most directly comparable GAAP financial measure, for each period shown is provided as part of the following tables, and a description of each non-GAAP financial measure is provided below.

Total Consolidated Costs of Revenues: For the Company as a whole, this measure is equal to total costs of revenues, as reported in the Company's Consolidated Statements of Comprehensive Income (Loss). For the Stillwater Mine, the East Boulder Mine, and PGM Recycling and Other, the Company segregates the expenses within total costs of revenues that are directly associated with each of these activities and then allocates the remaining facility costs included in total cost of revenues in proportion to the monthly volumes from each activity. The resulting total costs of revenues measures for the Stillwater Mine, the East Boulder Mine and PGM Recycling and Other are equal, in the aggregate, to total consolidated costs of revenues as reported in the Company’s Consolidated Statements of Comprehensive Income (Loss).

Total Cash Costs (Non-GAAP): This non-GAAP financial measure is calculated as total costs of revenues adjusted to exclude costs of metals sold from PGM Recycling, depletion and depreciation and amortization for Mine Production and PGM Recycling (including in inventory), asset retirement costs, and timing differences resulting from changes in product inventories to arrive at Total Cash Costs before by-product and recycling credits. From this calculation, the Company deducts by-product and recycling income credits to arrive at Total Cash Costs, net of by-product and recycling credits. Total Cash Costs is a measure of extraction efficiency. The Company uses this measure as a comparative indication of the cash costs related to production and processing in its mining operations in any period.

When divided by the total tons milled in the respective period, Total Cash Costs per Ore Ton Milled (Non-GAAP), measured for each mine or combined, provides an indication of the level of cash costs incurred per ton milled in that period. Because of variability of ore grade in the Company’s mining operations, production efficiency underground is frequently measured against ore tons produced rather than contained PGM ounces. Because ore tons are first weighed as they are fed into the mill, mill feed is the first point at which production tons are measured precisely. Consequently, Total Cash Costs per Ore Ton Milled (Non-GAAP) is a general measure of production efficiency, and is affected both by the level of Total Cash Costs (Non-GAAP) and by the volume of tons produced and fed to the mill.

When divided by the total recoverable PGM ounces from production in the respective period, Total Cash Costs per PGM Mined Ounce (Non-GAAP), measured for each mine or combined, provides an indication of the level of cash costs incurred per PGM mined ounce produced in that period. Recoverable PGM ounces from production are an indication of the amount of PGM product mined in any period. Because ultimately extracting PGM material is the objective of mining, the cash cost per PGM mined ounce of extracting and processing PGM ounces in a period is a useful measure for comparing extraction efficiency between periods and between the Company’s mines. Consequently, Total Cash Costs per PGM Mined Ounce (Non-GAAP) in any period is a general measure of extraction efficiency, and is affected by the level of Total Cash Costs (Non-GAAP), by the grade of the ore produced and by the volume of ore produced in the period.

All-In Sustaining Costs

(Non-GAAP Financial Measure)

(Unaudited)

All-In Sustaining Costs (Non-GAAP): This non-GAAP financial measure is used as an indicator from period to period of the level of total cash required by the Company to maintain and operate the existing mines, including corporate administrative costs and replacement capital. The measure is calculated beginning with total combined cash costs, net of credits (another non-GAAP financial measure, described above), and adding to it the recycling income credit, domestic corporate general and administrative costs (excluding any depreciation and general and administrative costs of foreign subsidiaries) and that portion of total capital expenditures associated with sustaining the current level of mining operations. Capital expenditures, however, for Blitz, Graham Creek (prior to 2015) and certain other one-time projects are not included in the calculation.

When divided by the total recoverable PGM mined ounces produced in the respective period, All-In Sustaining Costs per PGM Mined Ounce (Non-GAAP) provides an indication of the level of total cash required to maintain and operate the mines per PGM ounce produced in the period. Recoverable PGM ounces from production are an indication of the amount of PGM product extracted through mining in any period. Because the objective of PGM mining activity is to extract PGM material, the all-in cash costs per PGM mined ounce to produce PGM material, administer the business and sustain the operating capacity of the mines is a useful measure for comparing overall extraction efficiency between periods. This measure is affected by the total level of spending in the period and by the grade and volume of mined ore produced.

Underlying Earnings (Loss)

(Non-GAAP Financial Measure)

(Unaudited)

Underlying Earnings (Loss) (Non-GAAP): This non-GAAP financial measure is considered by the Company to be reflective of the actual income / loss position. This non-GAAP financial measure provides to investors and analysts the ability to understand the results of the continuing operations of the Company relating to the production, processing and sale of PGMs, by excluding certain items that have a disproportionate impact on the results for the reported periods. The measure is calculated beginning with Net income (loss) attributable to common stockholders and adding back impairment charges, one-time event charges and charges infrequent to the Company's continuing operations and the income tax effect of such adjustment. Net loss attributable to noncontrolling interest has been adjusted for the noncontrolling interest's ownership percentage of any applicable impairment charges to which the noncontrolling interest has an ownership. The Company's determination of the components of Underlying earnings (loss) are evaluated periodically and based, in part, on a review of non-GAAP financial measures used by mining industry analysts.

Net income (loss) attributable to common stockholders is reconciled to Adjusted net income (loss) attributable to common stockholders and Underlying earnings (loss) as follows:

ITEM 3

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to market risk, including the effects of adverse changes in metal prices, interest rates and foreign currencies as discussed below.

COMMODITY PRICE RISK

The Company sells its mined palladium, platinum and associated by-product metals to its customers at prices approximating current market prices. As a result, the Company's financial performance is sensitive to fluctuations in the market prices for these materials. In order to ensure demand for its products persists throughout pricing cycles, the Company has entered into supply agreements with customers covering sales of its mine production. The Company also attempts to maintain adequate liquidity on hand to sustain its operations through downturns in PGM prices.

In its PGM recycling activities, the Company customarily enters into fixed forward sales to mitigate its pricing exposure. The terms of a fixed forward sales transaction commit the Company to deliver a specified number of metal ounces on a particular future date at a stipulated price. At the time it enters into the forward sales commitment, the Company also utilizes the price offered in the forward markets to determine the price it is willing to pay to purchase the recycled materials. Because the forward price is used simultaneously to determine both the acquisition price and the ultimate selling price of the recycled ounces, this arrangement significantly reduces the Company's exposure to PGM price volatility in its recycling activities. The Company believes such transactions qualify for the exception to hedge accounting treatment and so has elected to account for these transactions as normal purchases and normal sales. For further information regarding the Company's fixed forward contracts, see "Note 5 - Derivative Instruments" in the notes to the Company's consolidated financial statements included in this document.

INTEREST RATE RISK

At June 30, 2016, all of the Company’s outstanding long-term debt obligations bore fixed rates of interest that are not subject to adjustment as current market interest rates change. Financing income earned on advance payments the Company makes to its recycling suppliers is generally linked to short-term inter-bank rates, which do fluctuate with market interest rates.

The Company’s convertible debentures do not contain financial covenants. The Company projects that the total cash cost to service its debt in 2016, including payments of principal and interest, will be approximately $6.4 million. The Company believes it has adequate liquidity available to meet its outstanding debt service obligations.

The Company customarily invests its excess cash balances in short-term instruments, which it classifies as "available-for-sale." The Company prioritizes its objectives for these investments in order of (1) preservation of principal, (2) maintenance of liquidity, and (3) return on investment, with the first two objectives taking precedence. In the current low interest rate environment, the Company has determined to restrict its investment of these cash balances to instruments backed by the full faith and credit of the United States government. Although this should adequately secure the invested principal, there can be no guarantee that future changes in interest rates or other market disruptions will not have a negative effect on the value and liquidity of investments made by the Company.

FOREIGN CURRENCY RISK

The Company has some nominal exposure to Canadian, Argentine and other foreign currencies. These exposures currently are limited to foreign cash deposits and expenses incurred for the services of foreign-based employees and contractors, along with some associated support costs. The Company does not specifically hedge this exposure.

For the second quarter of 2016, the Company experienced a minimal effect due to foreign currency fluctuations as compared to a foreign currency transaction gain of $0.7 million in the second quarter of 2015, mostly attributable to the stabilizing of the Argentine peso.

ITEM 4

CONTROLS AND PROCEDURES


(a)	Disclosure Controls and Procedures.

The Company’s management, with the participation of the Company’s President and Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this report. Based on such evaluation, the Company’s President and Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act.

In designing and evaluating the Company’s disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and well operated, can provide only reasonable, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, the Company’s management was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The Company also designed disclosure controls and procedures based in part upon 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.


(b)	Internal Control Over Financial Reporting.

In reviewing internal control over financial reporting based upon the framework in Internal Control Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) at June 30, 2016, management determined that during the second quarter of 2016 there were no changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1

LEGAL PROCEEDINGS

The Company is involved in various claims and legal actions arising in the ordinary course of business, primarily consisting of employee lawsuits and employee injury claims. In the opinion of management, the ultimate disposition of these types of matters is not expected to have a material adverse effect on the Company’s consolidated financial position, results of operations or liquidity.

ITEM 1A

RISK FACTORS

The Company filed its Form 10-K, with the Securities and Exchange Commission on February 22, 2016, which sets forth certain risk factors associated with the Company in Item 1A, Risk Factors therein.

There have been no material changes to the risk factors as previously disclosed in the Company's Form 10-K.

ITEM 4

MINE SAFETY DISCLOSURES

Valuing the people in the Company's workforce means being committed to their safety and well-being at all times. The Company's goal is that “Everyone Goes Home Safe Every Day”. The Company's Safety & Health Management System, G.E.T. Safe, promotes a safety culture based on safety leadership and teamwork to improve safety performance. The Company's G.E.T. Safe Management System is very comprehensive. Included in the system are incidence tracking and analysis, near miss reporting, hazard recognition, workplace inspections, pre-operational equipment inspections, team safety meetings, annual refresher training, task training, standard operating procedures training, safety sweeps, audits, stand-downs and employee engagement activities focused on working safely. The Company works closely with Mine Safety and Health Administration (MSHA) inspectors to act on their findings and incorporate their suggestions. Management also strives to maintain a consistent “tone at the top” that working safely every day is paramount to the overall success of the Company.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"), each operator of a coal or other mine is required to include certain mine safety results within its periodic reports filed with the Securities and Exchange Commission. In accordance with the reporting requirements included in Section 1503(a) of the Dodd-Frank Act and Item 104 of Regulation S-K (17 CFR 229.104), the required mine safety results regarding certain mining safety and health matters for each of the Company’s mine locations that are covered under the scope of the Dodd-Frank Act are included in Exhibit 95 - Mine Safety Disclosures of the Company's Form 10-K. In the second quarter of 2016, the Company received a total of six violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a coal or other mine safety or health hazard under Section 104 of the Federal Mine Safety and Health Act. See "Exhibit 95 - Mine Safety Disclosures" of this Quarterly Report on Form 10-Q for more information.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	GENERAL In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary to fairly present the financial position of Stillwater Mining Company (the “Company”) at June 30, 2016, and the results of its operations for the three and six months ended June 30, 2016 and 2015, respectively and cash flows for the six months ended June 30, 2016 and 2015, respectively. The results of operations for the first six months of 2016 are not necessarily indicative of the results to be expected for the 2016 year. The accompanying consolidated financial statements in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's 2015 Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 22, 2016 (Form 10-K). All inter-company transactions and balances have been eliminated in consolidation. The preparation of the Company’s consolidated financial statements in conformity with United States generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes. The more significant areas requiring the use of management’s estimates relate to mineral reserves, reclamation and environmental obligations, valuation allowance for deferred tax assets, useful lives utilized for depreciation, amortization and accretion calculations, future cash flows from long-lived assets, and fair value of derivatives and other financial instruments. Actual results could differ from these estimates. On May 28, 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue it expects to be entitled to for the transfer of promised goods or services to customers. In August 2015, the FASB issued ASU 2015-14, Deferral of the Effective Date, which defers the effective date of ASU 2014-09 by one year to January 1, 2018. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP. The standard permits the use of either the retrospective or cumulative effect transition method. The Company continues to evaluate the effect that ASU 2014-09 will have on its consolidated financial statements and disclosures and has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. Early adoption is not permitted. On April 7, 2015, as part of its initiative to simplify and reduce complexity in financial statements, the FASB issued ASU 2015-03, Interest - Imputation, (Subtopic 835-30): Simplifying the Presentation of Debt Issuance. This ASU requires the debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. Also, it requires retrospective application for all prior periods presented in the financial statements and a disclosure of the nature of and reason for the change in accounting principle, the transition method, a description of the prior-period information that has been retrospectively adjusted and the effect of the change on the financial statement line items. ASU 2015-03 is effective for financial statements issued for fiscal years beginning after December 31, 2015, and interim periods within those fiscal years. Early adoption was permitted for financial statements that had not been previously issued. The Company elected early adoption of ASU 2015-03 and reclassified Deferred debt issue costs against the related liability for all periods presented. Prior to the adoption of ASU 2015-03, the balance reported at December 31, 2015 for total Long-term debt and capital lease obligations was $258.9 million, and after adoption and reclassification of Deferred debt issue costs of $3.8 million, the total balance reported at December 31, 2015 became $255.1 million. On July 22, 2015, as part of its initiative to simplify and reduce complexity in financial statements, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. ASU 2015-11, which will change the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. ASU 2015-11 is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company is evaluating the effect that ASU 2015-11 will have on its consolidated financial statements and disclosures and has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. The ASU requires prospective adoption and permits early adoption. On February 25, 2016, the FASB issued ASU 2016-02, Leases, (Topic 840), which requires an entity that leases assets, with terms of more than 12 months, to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. ASU 2016-02 is effective for financial statements issued for fiscal years beginning after December 31, 2018, and interim periods within those fiscal years. The Company is evaluating the effect that ASU 2016-02 will have on its consolidated financial statements and disclosures and has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. Early adoption is permitted. On March 30, 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employees Shared-Based Payment Accounting. The ASU will change several aspects within share based payments: (1) accounting for income taxes, (2) classification of excess tax benefits, (3) forfeitures, (4) minimum statutory tax withholding requirements, (5) classification of employee taxes paid when an employer withholds shares for tax-withholding purposes, (6) practical expedient - expected term, (7) intrinsic value, and (8) eliminating the indefinite deferral. ASU 2016-09 is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company is evaluating the effect that ASU 2016-09 will have on its consolidated financial statements and disclosures and has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. Early adoption is permitted in any interim or annual period provided that the entire ASU is adopted.

Asset Impairment	6 Months Ended
Asset Impairment	Jun. 30, 2016
Property, Plant and Equipment [Abstract]
Asset Impairment	ASSET IMPAIRMENT In accordance with the FASB Accounting Standards Codification 360, Property Plant and Equipment, (ASC 360-10), the Company reviews and evaluates its long-lived assets for impairment when events and changes in circumstances indicate that the related carrying amounts of such assets may not be recoverable and may exceed their fair value. For purposes of determining impairment, assets are grouped at the lowest level for which identifiable cash flows (including estimated future cash flows from non-operating properties) are largely independent of the cash flows of other groups of assets and liabilities. The Company determined there were no material events or circumstances requiring the Company to test long-lived assets for impairment at June 30, 2016. However, during the second quarter of 2015, the Company concluded that there was evidence to suggest that there had been a significant decrease in the fair value of the Marathon mineral properties. Accordingly, the Company performed an analysis that indicated the carrying value of the Marathon mineral properties exceeded its recoverable amount at June 30, 2015. The Company undertook an assessment of the fair value of its Marathon mineral properties, which included the examination of recent comparable transactions. At June 30, 2015, the Company recorded an impairment charge of $46.8 million (before-tax) against the carrying value of the Marathon mineral properties in Canada, reducing its carrying value to an estimated fair value of $8.6 million.
