Accounting Policies [Abstract]

Significant Accounting Policies

Note 1: Significant Accounting Policies

Basis of Consolidation. The consolidated financial statements include the accounts of Universal Stainless & Alloy Products, Inc. and its wholly-owned subsidiaries (collectively, “we,” “us,” “our,” or the “Company”). All intercompany accounts and transactions have been eliminated in consolidation. We have no interests in any unconsolidated entity.

Use of Estimates. The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements. The estimates and assumptions used in these consolidated financial statements are based on known information available as of the balance sheet date. Actual results could differ from those estimates.

Concentration of Credit Risk. We limit our credit risk on accounts receivable by performing ongoing credit evaluations and, when deemed necessary, require letters of credit, guarantees or cash collateral. During 2017, we had one customer which accounted for more than 17% of our total net sales and for 3% of our total accounts receivable balance. During 2016, we had one customer that accounted for more than 20% of our total net sales and for 4% of our total accounts receivable balance. During 2015, we had one customer that accounted for more than 16% of our total net sales and for 7% of our total accounts receivable balance.

Accounts Receivable and Allowance for Doubtful Accounts. Accounts receivable are presented net of the allowance for doubtful accounts on our consolidated balance sheets. We market our products to a diverse customer base, primarily throughout the United States. International sales approximated 9%, of 2017, 2016 and 2015 total net sales. The allowance for doubtful accounts includes specific reserves for the value of outstanding invoices issued to customers that are deemed potentially not collectible. Receivables are charged-off to the allowance when they are deemed to be uncollectible. Bad debt expense, net of recoveries, was $0.2 million for the years ended December 31, 2017, 2016 and 2015.

Inventories. Inventories are stated at the lower of cost or market with cost principally determined by the weighted average cost method. Such costs include the acquisition cost for raw materials and supplies, direct labor and applied manufacturing overhead within the guidelines of normal plant capacity. We reserve for slow-moving inventory and inventory that is being evaluated under our quality control process. The reserves are based upon management’s expected method of disposition. The net change in inventory reserves for the year ended December 31, 2017 was an increase of $0.7 million, primarily due to the aging of slow moving material. The net change in inventory reserves for the years ended December 31, 2016 and 2015 was a $0.5 million increase and a $0.1 million decrease, respectively.

Included in inventory are operating materials consisting of forge dies and production molds and rolls that are consumed over their useful lives. During the years ended December 31, 2017, 2016 and 2015, we amortized these operating materials in the amount of $2.1 million, $1.6 million and $1.8 million, respectively. This expense is recorded as a component of cost of products sold on the consolidated statements of operations and included as a part of our total depreciation and amortization on the consolidated statements of cash flows.

Property, Plant and Equipment. Property, plant and equipment is recorded at cost or its fair value at acquisition date. No depreciation is recognized on assets until they are placed in service. Assets which have been retired or disposed of are removed from cost and accumulated depreciation accounts, with the gain or loss generally reflected in cost of goods sold on the consolidated statements of operations.

Major equipment maintenance costs are capitalized as incurred and included in other current assets. These costs are amortized to cost of products sold within a twelve to thirty-six month period. Other maintenance costs are expensed as incurred. Costs of improvements and renewals are capitalized. Our maintenance expense for the years ended December 31, 2017, 2016 and 2015 was $18.8 million, $15.7 million and $16.9 million, respectively, which is included as a component of cost of products sold.

Depreciation is computed using the straight-line method based on the estimated useful lives of the related assets. The estimated useful lives of buildings and land improvements are between 10 and 39 years, and the estimated useful lives of machinery and equipment are between five and 20 years. Our total depreciation expense for the years ended December 31, 2017, 2016 and 2015 was $16.5 million, $16.7 million and $15.8 million, respectively, of which $16.2 million, $16.3 million and $15.4 million, respectively, was included as a component of cost of products sold while the remainder was included in selling, general and administrative expense.

Long-Lived Asset Impairment. Long-lived assets, including property, plant and equipment and intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable in relation to the operating performance and future undiscounted cash flows of the underlying assets. Adjustments are made if the sum of expected future cash flows is less than the book value. Based on management’s assessment of the carrying values of long-lived assets, no impairment reserve was deemed necessary as of December 31, 2017, 2016 and 2015. Our intangible assets were fully amortized at December 31, 2015.

Deferred Financing Costs. Deferred financing costs are amortized up to the maturity date of the related financial instrument using the straight-line method, which approximates the effective interest method. Deferred financing cost amortization for the years ended December 31, 2017, 2016 and 2015 was $0.3 million, $0.2 million and $0.6 million, respectively, and is included as a component of interest expense and other financing costs on the consolidated statements of operations and included as part of total depreciation and amortization on the consolidated statements of cash flows. In the first quarter of 2016, the Company wrote off $0.8 million of deferred financing costs related to the prior credit facility due to entering into the new Credit Agreement on January 21, 2016. These costs are included as a component of interest expense and other financing costs on the consolidated statements of operations and are broken out separately on the consolidated statement of cash flows. At December 31, 2017 and 2016, we had $0.7 million and $1.0 million, respectively, of unamortized deferred financing costs included on our consolidated balance sheets as a reduction of debt.

Goodwill. Goodwill, which represents the excess of cost over net tangible and identifiable intangible assets of acquired businesses, is stated at fair value. Goodwill is not amortized, but evaluated or tested annually for impairment or more frequently if any event indicates that the carrying amount of goodwill may be impaired.

We recorded a goodwill impairment in the third quarter of 2015. Due to a significant and sustained drop in our share price and continued weak operating results driven by slower market conditions, the Company determined that an interim goodwill impairment review was required in accordance with Accounting Standards Codification (“ASC”) 350, “Intangibles – Goodwill and Other”. Based on the guidance in ASC 350, the Company performed the two-step quantitative analysis. Under the first step, the Company determined that the carrying value exceeded the fair value of the Company and, therefore, the second step of the analysis was performed. The fair value was estimated using a combination of an income approach, which estimates fair value based on projected discounted cash flows and a market approach, which estimates fair value using the recent stock price of the Company. The income approach is supported by a Level 3 fair value measurement, which means that the valuation reflects the Company’s own estimates of market participant assumptions. The market approach is supported by a Level 1 fair value measurement which is the observable stock price of the Company. The income approach was weighted 30% and the market approach was weighted 70% in determining the fair value. This assessment resulted in the recognition of a non-cash goodwill impairment charge of $20.3 million, which eliminated all goodwill from the balance sheet at September 30, 2015.

Stockholders’ Equity. We have never paid a cash dividend on our common stock. Our Credit Agreement does not permit the payment of cash dividends.

Revenue Recognition. Revenue from the sale of products is recognized when both risk of loss and title have transferred to the customer, which in most cases coincides with shipment of the related products, and collection is reasonably assured. Revenue from conversion services is recognized when the performance of the service is complete. Invoiced shipping and handling costs are also accounted for as revenue. Customer claims, which are not material, are accounted for primarily as a reduction to gross sales after the matter has been researched and an acceptable resolution has been reached.

The following table presents net sales by product line:

For the years ended December 31,	2017		2016		2015
(dollars in thousands)
Stainless steel	$	139,603	$	112,118	$	135,945
High-strength low alloy steel		15,693		13,180		16,045
Tool steel		32,279		19,179		16,197
High-temperature alloy steel		12,435		6,057		7,557
Conversion services and other sales		2,633		3,900		4,916
Total net sales	$	202,643	$	154,434	$	180,660

Income Taxes. Deferred income taxes are provided for net operating losses, unused tax credits earned and the tax effect of temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements. We use the liability method to account for income taxes, which requires deferred taxes to be recorded at the statutory rate expected to be in effect when the taxes are paid. Valuation allowances are provided for a deferred tax asset when it is more likely than not that the asset will not be realized. Income tax penalties and interest are included in the provision for income tax expense.

We evaluate the tax positions taken or expected to be taken in our tax returns. A tax position should only be recognized in the financial statements if we determine that it is more-likely-than-not that the tax position will be sustained upon examination by the tax authorities, based upon the technical merits of the position. For those tax positions that should be recognized, the measurement of a tax position is determined as being the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. We believe there are no material uncertain tax positions at December 31, 2017, 2016 and 2015.

We use the with-and-without method to account for excess tax benefits recognized as a result of the exercise of employee stock options. Under the with-and-without method, excess tax benefits related to share-based compensation are not deemed to be realized until after the utilization of all other tax benefits available to us, which are also subject to applicable limitations.

Share-based Compensation Plans. We recognize compensation expense based on the grant-date fair value of the awards. The fair value of the stock option grants is estimated on the date of grant using the Black-Scholes option-pricing model, and is recognized ratably over the service/vesting period of the award. The fair value of time-based restricted stock grants and restricted stock units is calculated using the market value of the stock on the date of issuance, and is recognized ratably over the service/vesting period of the award.

Net Income (Loss) per Common Share. Net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per common share is computed by dividing net income (loss), adjusted to include interest expense (tax effected) for the convertible notes by the weighted-average number of common shares outstanding plus all dilutive potential common shares outstanding during the period. All shares that were issuable under our outstanding Notes were considered outstanding for our diluted net income per common share computation, using the “if converted” method of accounting from the date of issuance.

Treasury Stock. We account for treasury stock under the cost method and include such shares as a reduction of total stockholders’ equity.

Financial Instruments. Financial instruments held by us include cash, accounts receivable, and accounts payable and current and long-term debt. The carrying value of cash, accounts receivable and accounts payable is considered to be representative of fair value because of the short maturity of these instruments. Refer to Note 5 for fair value disclosures of our financial instruments.

Segment Reporting. Our operating facilities are integrated, and therefore our chief operating decision maker (“CODM”) views the Company as one business unit. Our CODM sets performance goals, assesses performance and makes decisions about resource allocations on a consolidated basis. As a result of these factors, as well as the nature of the financial information available which is reviewed by our CODM, we maintain one reportable segment.

Recently Adopted Accounting Pronouncement

Effective January 1, 2017, we adopted the Financial Accounting Standards Board (“FASB”) Accounting Standard Update (“ASU”) 2016-09 “Improvements to Employee Share-Based Payment Accounting”. The ASU includes multiple provisions intended to simplify various aspects of the accounting for share-based payments. Excess tax benefits for share-based payments will be recorded as a reduction of income taxes and reflected in operating cash flows upon the adoption of this ASU, eliminating additional paid in capital (“APIC”) pools. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. This ASU also eliminates the requirement that excess tax benefits be realized before companies can recognize them. As a result of the implementation of this guidance, we recorded an adjustment to retained earnings of $0.8 million and a corresponding deferred tax asset for the cumulative effect of excess tax benefits that were not previously recognized. We recorded $0.4 million of tax expense as discrete items in the twelve months ended December 31, 2017 for the expiration of stock options. This amount would have been recorded to APIC under previous guidance. We have elected to account for forfeitures as they occur.

Effective January 1, 2017, we adopted the FASB ASU 2015-11 “Simplifying the Measurement of Inventory”. This ASU simplifies the guidance on the subsequent measurement of inventory, excluding inventory measured using last-in, first out or the retail inventory method. Under the new standard, inventory should be valued at the lower of cost or net realizable value. The implementation of this guidance did not have a material impact on our financial statements.

Recently Issued Accounting Pronouncements

The Company considers the applicability and impact of all ASUs. Recently issued ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15 “Classification of Certain Cash Receipts and Cash Payments”. This ASU addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, “Statement of Cash Flows”, and other Topics. ASU 2016-15 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. We do not expect the adoption of this guidance to have a material impact on the financial statements.

In February 2016, the FASB issued ASU 2016-2 “Leases (Topic 842)”. The ASU requires lessees to recognize most leases on their balance sheet as a right-of-use asset and a lease liability. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. The criteria for evaluating are similar to those applied in current leases accounting. This guidance is effective for annual and interim reporting periods beginning after December 15, 2018 with early adoption permitted. We do not expect the adoption of this guidance to have a material impact on the financial statements due to having a limited number of operating leases.

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers (Topic 606)”. This topic converges the guidance within U.S. GAAP and International Financial Reporting Standards and supersedes Accounting Standards Codification 605, Revenue Recognition. The new standard requires companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard will also result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively, and improve guidance for multiple-element arrangements. The new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. We have evaluated this guidance, and determined that the accounting treatment would change for a small, select group of the products we produce. We do not expect that implementation in the first quarter of 2018 using the modified retrospective approach will have a material effect on revenue, gross margin or operating income.

Credit Facility

On January 21, 2016, we entered into a new Revolving Credit, Term Loan and Security Agreement (the “Credit Agreement”) with PNC Bank, National Association, as administrative agent and co-collateral agent, Bank of America, N.A., as co-collateral agent, and PNC Capital Markets LLC, as sole lead arranger and sole bookrunner. The Credit Agreement provides for a senior secured revolving credit facility not to exceed $65.0 million (the “Revolving Credit Facility”) and a senior secured term loan facility (the “Term Loan”) in the amount of $30.0 million (together with the Revolving Credit Facility, the “Facilities”). The Credit Agreement also provides for a letter of credit sub-facility not to exceed $10.0 million and a swing loan sub-facility not to exceed $6.5 million. The Company may request to increase the maximum aggregate principal amount of borrowings under the Revolving Credit Facility by $25.0 million prior to January 21, 2020. The Credit Agreement replaced the previous credit agreement that was in place prior to January 21, 2016. The Company was in compliance with all applicable financial covenants set forth in the previous credit agreement as of the date of its entrance into the Credit Agreement.

The Facilities, which expire upon the earlier of (i) January 21, 2021 or (ii) the date that is 90 days prior to the scheduled maturity date of the Notes (as defined below) (in either case, the “Expiration Date”), are collateralized by a first lien in substantially all of the assets of the Company and its subsidiaries, except that no real property is collateral under the Facilities other than the Company’s real property in North Jackson, Ohio.

Availability under the Revolving Credit Facility is based on eligible accounts receivable and inventory. The Company is required to pay a commitment fee of 0.25% based on the daily unused portion of the Revolving Credit Facility.

With respect to the Term Loan, the Company makes quarterly installment payments of principal of approximately $1.1 million, plus accrued and unpaid interest, on the first day of each fiscal quarter. To the extent not previously paid, the Term Loan will become due and payable in full on the Expiration Date.

Amounts outstanding under the Facilities, at the Company’s option, will bear interest at either a base rate plus a margin or a rate based on LIBOR plus a margin, in either case calculated in accordance with the terms of the Credit Agreement. Interest under the Credit Agreement is payable monthly. We elected to use the LIBOR based rate for the majority of the debt outstanding under the Facilities for the twelve months ended December 31, 2017, which was 3.37% on our Revolving Credit Facility and 3.87% for the Term Loan at December 31, 2017.

On October 23, 2017, the Company announced that it obtained a favorable amendment to the Credit Agreement that lowers the Company’s interest on its senior bank borrowings by 75 basis points. At current borrowing levels, this change will reduce annual interest expense by approximately $0.4 million. In addition, several terms of the Credit agreement were amended and will provide additional liquidity to the Company.

The Credit Agreement contains customary affirmative and negative covenants. As of December 31, 2016, and as of the end of each fiscal quarter ending thereafter, the Company must maintain a fixed charge coverage ratio of not less than 1.10 to 1.0, in each case measured on a rolling four-quarter basis calculated in accordance with the terms of the Credit Agreement. The October 23, 2017 amendment made no changes to the financial covenants. We were in compliance with our covenants under the Credit Agreement at December 31, 2017and 2016.

At December 31, 2017, we had deferred financing costs of approximately $0.7 million, and amortized $0.3 million of deferred financing costs for the twelve months ended December31, 2017. For the twelve months ended December 31, 2016, we paid deferred financing costs of $0.8 million related to the Credit Agreement, wrote off $0.8 million of fees related to the previous credit agreement and amortized $0.2 million of deferred financing costs.

Pursuant to the terms of the Credit Agreement, the Company completed the issuance of 73,207 shares of the Company’s common stock to certain directors and officers of the Company on February 2, 2016. The aggregate purchase price of the stock was $0.5 million based on the average of the high and low reported trading prices for the Company’s common stock on The NASDAQ Stock Market on February 1, 2016.

The aggregate annual principal payments due under our Credit Agreement at December 31, 2017, are as follows:

(dollars in thousands)
2018	$	4,286
2019		4,286

Notes

On January 21, 2016, the Company entered into the Notes in the aggregate principal amount of $20.0 million, each in favor of Gorbert Inc. (the “Holder”). The Notes amended and restated the Convertible Notes. The Company’s obligations under the Notes are collateralized by a second lien on the same assets of the Company that collateralize the obligations of the Company under the Facilities. The Notes mature on March 17, 2019, and the maturity date may be extended, at the Company’s option, to March 17, 2020 and further to March 17, 2021. If the Company elects to extend the maturity date of the Notes to March 17, 2020, principal payments in the aggregate of $2.0 million will be required within 10 days of March 7, 2019. If the Company elects to extend the maturity date of the Notes further to March 17, 2021, principal payments in the aggregate of $2.0 million will be required within 10 days of March 7, 2020.

The Notes bore interest at a rate of 4.0% per year through and including August 17, 2016. The Notes bear interest at a rate of 5.0% per year from August 18, 2016 through and including August 17, 2017 and a rate of 6.0% per year from and after August 18, 2017. Through and including June 18, 2017, all accrued and unpaid interest is payable semi-annually in arrears on each June 18 and December 18. After June 18, 2017, all accrued and unpaid interest is payable quarterly in arrears on each September 18, December 18, March 18 and June 18.

The Holder could have elected at any time on or prior to August 17, 2017 to convert all or any portion of the outstanding principal amount of the Notes which is an integral multiple of $100,000. The Notes are convertible into shares of common stock and, in certain circumstances, cash, securities and/or other assets. The Notes were convertible based on an initial conversion rate of 21.2 shares of Common Stock per $1,000 principal amount of the Notes (equivalent to an initial conversion price of $47.1675 per share). The conversion rate and the conversion price associated with the Notes could have been adjusted in certain circumstances. The Holder did not exercise the conversion rights prior to their expiration, and the rights are now void.

In conjunction with the issuance of the Notes on January 21, 2016, we made principal prepayments on the Notes totaling $1.0 million.

Capital Leases

Throughout 2017, the company entered into four capital leases for office and manufacturing equipment, with lease terms between three and six years. The assets are included in Property, plant and equipment, net on the Consolidated Balance Sheet and are depreciated over the term of each lease. The long-term component of the capital lease obligations is included in Long-term debt and the current component is included in Current portion of long-term debt. These amounts have been excluded from the Consolidated Statement of Cash Flows as they are non-cash. The net present value of the minimum lease payments, at inception, was $0.5 million.

On February 1, 2016 and March 1, 2016, the Company entered into capital leases for equipment, each with a term of five years. The net present value of the minimum lease payments, at inception, was $2.0 million.

As of December 31, 2017, future minimum lease payments applicable to capital leases were as follows:

2018		591
2019		591
2020		569
2021		467
2022		56

Less amounts representing interest		(392	)
Present value of net minimum capital lease payments	$	1,897
Less current obligation		(422	)
Total long-term capital lease obligation	$	1,475

There were no capital lease obligations at December 31, 2015. Accumulated amortization of capital lease assets as of December 31, 2017 was $0.7 million, of which $0.4 million and $0.3 million was amortized for the twelve months ended December 31, 2017 and 2016, respectively. Capital lease amortization is included in cost of products sold in the Consolidated Statement of Operations.

Fair Value Measurements	12 Months Ended
Fair Value Measurements	Dec. 31, 2017
Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 5: Fair Value Measurements The fair value hierarchy has three levels based on the inputs used to determine fair value, which are as follows: Level 1 — Unadjusted quoted prices available in active markets for the identical assets or liabilities at the measurement date. Level 2 — Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability. Level 3 — Unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The fair value hierarchy requires the use of observable market data when available. In instances where the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input significant to the fair value measurement in its entirety. Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. The carrying amounts of our cash, accounts receivable and accounts payable approximated fair value at December 31, 2017 and 2016 due to their short-term nature (Level 1). The fair value of the Term Loan and Revolver at December 31, 2017 and 2016 approximated the carrying amount as the interest rate is based upon floating short-term interest rates (Level 2). At December 31, 2017 and 2016, the fair value of our Notes was approximately $18.8 million and $18.4 million, respectively (Level 2).

The Tax Cuts and Jobs Act (the “Tax Act”) was signed into law on December 22, 2017. The Tax Act changed many aspects of U.S. corporate income taxation and included reduction of the corporate income tax rate from 35% to 21%, effective for tax years beginning in 2018. We recognized the tax effects of the Tax Act in the year ended December 31, 2017 and recorded $8.3 million in tax benefits, which relates almost entirely to the remeasurement of deferred tax liabilities to the 21% tax rate. The Company expects the Tax Act changes to result in an effective tax rate of approximately 20% in 2018 and thereafter. Upon completion of our 2017 U.S. income tax return in 2018 we may identify additional remeasurement adjustments to our recorded deferred tax liabilities. We will continue to assess our provision for income taxes as future guidance is issued but do not currently anticipate significant revisions will be necessary. Any such revisions will be treated in accordance with the measurement period guidance outlined in Staff Accounting Bulletin No. 118.

In 2017, we recorded a $0.5 million valuation allowance against our Pennsylvania deferred tax assets due to a change in Pennsylvania tax law. We continue to record a full valuation allowance against our New York deferred tax assets due to the zero percent (0%) state income tax rate for qualified manufacturers. We have determined that federal and other state deferred tax assets are expected to be realized and have not recorded any additional valuation allowances.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of our net deferred taxes related to continuing operations are as follows:

December 31,	2017		2016

We file a U.S. federal income tax return and various state income tax returns. For federal income tax purposes, we had $45.0 million and $53.0 million of net operating loss carryforwards at December 31, 2017 and 2016, respectively. The net operating loss carryforwards begin to expire in 2031. In addition, we have credit carryforwards associated with our research and development activities of $3.1 million and $2.7 million as of December 31, 2017 and 2016, respectively. The research and development credit carryforwards being to expire in 2030.

We have state net operating loss carryforwards of $9.1 million and $9.2 million, of which $7.4 million and $0.0 million, respectively, have a valuation allowance, and state credit carryforwards of $0.2 and $0.3 million at December 31, 2017 and 2016, respectively. The valuation allowance was $2.5 million and $1.6 million at December 31, 2017 and 2016, respectively. The state net operating loss carryforwards begin to expire in 2031. The state credit carryforwards begin to expire in 2027.

We are routinely under audit by federal or state authorities. Our federal tax returns are subject to examination by the IRS for tax years after 2013. We are subject to examination by most state tax jurisdictions for tax years after 2013.

An adjustment for interest expense on convertible notes was excluded from the income per share calculation for the years ended December 31, 2017, 2016 and 2015 as a result of the convertible notes being antidilutive.

There were 590,350, 844,000 and 635,200 options to purchase shares of common stock, at an average price of $30.63, $27.13 and $30.67 for the years ended December 31, 2017, 2016 and 2015, respectively, that were not included in the computation of diluted net income (loss) per common share because their respective exercise prices were greater than the average market price of our common stock. The calculation of diluted earnings per share for the year ended December 31, 2017 excludes 268,351 shares, and for the year ended December 31, 2016 excludes 408,459 shares, and for the year ended December 31, 2015 excludes 428,140 shares, for the assumed conversion of the Notes as a result of the convertible notes being antidilutive. In addition, the calculation of diluted earnings per share for the year ended December 31, 2016 and 2015 would have included 6,575 and 21,774 shares, respectively, for the assumed exercise of options and restricted stock units under our share incentive plans except that we were in a net loss position and the impact would have been antidilutive.

Incentive Compensation Plans

Note 9: Incentive Compensation Plans

At December 31, 2017, we had four incentive compensation plans that are described below:

Universal Stainless & Alloy Products, Inc. 2017 Equity Incentive Plan

We maintain the Universal Stainless & Alloy Products, Inc. 2017 Equity Incentive Plan (the “2017 Plan”), which was approved by our stockholders in May 2017. The 2017 Plan permits the issuance of stock options, restricted stock, restricted stock units, other stock-based awards and performance awards to officers, employees, non-employee directors, and consultants and advisors to the Company. At inception, there were 568,357 shares authorized for issuance under the 2017 Plan.

When adopted, the 2017 Plan replaced the Omnibus Incentive Plan (“OIP”). Any awards outstanding under the OIP will remain subject to and be paid under the OIP. No new awards will be granted under the OIP. Any shares subject to outstanding awards under the OIP that cease to be subject to such awards after the adoption of the 2017 Plan will increase the shares authorized under the 2017 Plan. At December 31, 2017, there were 631,624 shares available for grant under the 2017 Plan.

Omnibus Incentive Plan

We maintain the OIP which was approved by our stockholders in May 2012. The OIP permits the issuance of stock options, restricted stock, restricted stock units and other stock-based awards to non-employee directors, other than those directors owning more than 5% of our outstanding common stock, consultants, officers and other key employees who are expected to contribute to our future growth and success. With the adoption of the 2017 Plan, no shares of common stock were available for grant at December 31, 2017 under OIP.

Stock Options

The option price for options granted under the both the 2017 Plan and OIP is equal to the fair market value of the common stock at the date of grant. Options granted to non-employee directors vest over a three-year period, and options granted to employees vest over a four-year period. All options under both the 2017 Plan and OIP will expire no later than ten years after the grant date. Forfeited options may be reissued and are included in the amount available for grants.

A summary of stock option activity as of and for the year ended December 31, 2017 is presented below:

Exercisable at December 31, 2017							636,850		$	26.56		4.5

Proceeds from stock option exercises totaled $0.3 million and $0.3 million for the years ended December 31, 2017 and 2015, respectively. There were no stock option exercises in 2016. Shares issued in connection with stock option exercises are issued from available authorized shares.

Based upon the closing stock price of $21.42 at December 31, 2017, the aggregate intrinsic value of outstanding and exercisable stock options was $2.9 million and $1.4 million, respectively. Intrinsic value of stock options is calculated as the amount by which the market price of our common stock exceeds the exercise price of the options. The aggregate intrinsic value of stock options exercised for the years ended December 31, 2017 and 2015 was $0.1 million and $0.1 million, respectively. The total fair value of stock option awards vested during the years ended December 31, 2017, 2016 and 2015 was $1.2 million, $1.2 million and $1.0 million, respectively.

Share-based compensation to employees and directors is recognized as compensation expense in the consolidated statements of operations based on the stock options fair value on the measurement date, which is the date of the grant. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods. The compensation expense recognized and its related tax effects are included in additional paid-in capital.

Share-based compensation expense related to stock options totaled $1.2 million, $1.3 million and $1.5 million for the years ended December 31, 2017, 2016 and 2015, respectively. Share-based compensation expense is recognized ratably over the requisite service period for all stock option awards. Unrecognized share-based compensation expense related to non-vested stock option awards totaled $1.7 million at December 31, 2017. At such date, the weighted-average period over which this unrecognized expense was expected to be recognized was 2.6 years. We recognized no tax benefit for the exercise of stock options during the years ended December 31, 2017, 2016 and 2015.

The fair value of our stock options granted is estimated on the measurement date, which is the date of grant. We use the Black-Scholes option-pricing model. Our determination of fair value of stock option awards on the date of grant is affected by our stock price as well as assumptions regarding our expected stock price volatility over the term of the awards, and actual and projected stock option exercise behaviors. The weighted-average grant-date fair value of stock options granted during the years ended December 31, 2017, 2016 and 2015 was $9.60, $5.85 and $6.99, respectively.

The assumptions used to determine the fair value of stock options granted are detailed in the table below:

	2017			2016			2015
Risk-free interest rate	1.92% to 2.29%			1.42% to 2.39%			1.77% to 2.19%
Dividend yield		0.0	%		0.0	%		0.0	%
Expected market price volatility	45% to 53%			51% to 53%			49% to 55%
Weighted-average expected market price volatility		47.4	%		51.0	%		52.6	%
Expected term	5.6 to 7.5 years			5.6 to 7.5 years			5.6 to 7.5 years

The risk-free interest rate was developed using the U.S. Treasury yield curve for periods equal to the expected life of the stock options at the grant date. No dividend yield was assumed because we do not pay cash dividends on common stock and currently have no plans to pay a dividend. Expected volatility is based on the long-term historical volatility (estimated over a period equal to the expected term of the stock options) of our common stock. In estimating the fair value of stock options under the Black-Scholes option-pricing model, separate groups of employees that have similar historical exercise behavior are considered separately. The expected term of options granted represents the period of time that options granted are expected to be outstanding.

Restricted Stock and Restricted Stock Units

A summary of restricted stock activity for the years ended December 31, 2017 and 2016 is presented below:

Balance, December 31, 2017		82,280		$		15.45

As of December 31, 2015, all of the restricted shares issued in 2012 had vested. Share-based compensation expense related to restricted stock totaled $0.4 million, $0.1 million, and $0.4 for the years ended December 31, 2017, 2016 and 2015, respectively.

During the year ended December 31, 2017, we granted 14,280 time-based restricted stock units to certain employees and directors. The restricted stock units vest over four years for employees and three years for directors. The fair value of the non-vested time-based restricted common stock awards was calculated using the market value of the stock on the date of issuance. During the year ended December 31, 2016, we granted 95,000 time-based restricted stock units to certain employees, which vest over two or four years. As of December 31, 2017, total unrecognized compensation cost related to non-vested time-based restricted stock units was $0.9 million. That cost is expected to be recognized over a weighted-average period of 2.4 years.

Under the 1996 Employee Stock Purchase Plan, as amended (the “Plan”), the Company is authorized to issue up to 300,000 shares of common stock to its full-time employees, nearly all of whom are eligible to participate. Under the terms of the Plan, employees can choose as of January 1 and July 1 of each year to have up to 10% of their total earnings withheld to purchase up to 100 shares of our common stock each six-month period. The purchase price of the stock is 85% of the lower of its beginning-of-the-period or end-of-the-period market prices. At December 31, 2017, we have issued 212,089 shares of common stock since the Plan’s inception.

Cash Incentive Plans

We have a variable incentive compensation plan covering certain key executives and senior management and profit-sharing plans and a key performance plan that cover the remaining employees. The variable incentive compensation plan aligns the compensation of executive officers and senior management with the performance expectations of the Board of Directors in order to motivate and reward them for the achievement of Company performance metrics. The profit-sharing plans provide for the sharing of pre-tax profits in excess of specified amounts at our Bridgeville, Dunkirk and Titusville facilities. The key performance plan provides a cash incentive for achieving certain performance metrics at our North Jackson facility. For the years ended December 31, 2017, 2016 and 2015, we expensed $1.9 million, $1.5 million and $1.0 million, respectively, under these cash incentive plans of which $1.4 million $0.4 million and $0.4 million, respectively, was included as a component of cost of products sold while the remainder was included in selling and administrative expense. At December 31, 2017 and 2016, we had liabilities of $1.2 million as a component of accrued employment costs on our consolidated balance sheets related to these cash incentive plans.

Retirement Plans

Note 10: Retirement Plans

We have a defined contribution retirement plan (“401(k) plan”) that covers substantially all employees. Pursuant to the 401(k) plan, participants may elect to make pre-tax and after-tax contributions, subject to certain limitations imposed under the Internal Revenue Code of 1986, as amended. In addition, we make periodic contributions to the 401(k) plan based on service for the Titusville and Dunkirk hourly employees and age for North Jackson hourly employees. We make periodic contributions for the salaried employees at all locations except for North Jackson based upon their service and their individual contribution to the 401(k) plan. For North Jackson salaried employees, we make periodic contributions based upon the employee’s age and their individual contributions.

We also participate in the Steelworkers Pension Trust (the “Trust”), a multi-employer defined-benefit pension plan that is open to all hourly and salary employees associated with the Bridgeville facility. We make periodic contributions to the Trust based on hours worked at a fixed rate for each hourly employee, as determined by the collective bargaining agreement, which expires in August 2018 and a fixed monthly contribution on behalf of each salary employee. The trustees of the Trust have provided us with the latest data available for the Trust year ending December 31, 2016. As of that date, the Trust is not fully funded. We could be held liable to the Trust for our own obligations, as well as those of other employers, due to our participation in the Trust. Contribution rates could increase if the Trust is required to adopt a funding improvement plan or a rehabilitation plan, if the performance of the Trust assets do not meet expectations, or as a result of future collectively-bargained wage and benefit agreements. If we choose to stop participating in the Trust, we may be required to pay the Trust an amount based on the underfunded status of the Trust, referred to as a withdrawal liability.

The Pension Protection Act (PPA) defines a zone status for each trust. Trusts in the green zone are at least 80% funded, trusts in the yellow zone are at least 65% funded, and trusts in the red zone are generally less than 65% funded. The Trust has utilized extended amortization provisions to amortize its losses from 2008. The Trust recertified its zone status after using the extended amortization provisions as allowed by law. The Trust has not implemented a funding improvement or rehabilitation plan, nor are such plans pending. Our contributions to the Trust have not exceeded more than 5% of the total contributions to the Trust.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 11: Commitments and Contingencies From time to time, various lawsuits and claims have been or may be asserted against us relating to the conduct of our business, including routine litigation relating to commercial and employment matters. The ultimate cost and outcome of any litigation or claim cannot be predicted with certainty. Management believes, based on information presently available, that the likelihood that the ultimate outcome of any such pending matter will have a material adverse effect on its financial condition, or liquidity or a material impact to its results of operations is remote, although the resolution of one or more of these matters may have a material adverse effect on our results of operations for the period in which the resolution occurs. We, as well as other steel companies, are subject to demanding environmental standards imposed by federal, state and local environmental laws and regulations. We are not aware of any environmental condition that currently exists at any of our facilities that would cause a material adverse effect on our financial condition, results of operations or liquidity in a particular future quarter or year. Our purchase obligations include the value of all open purchase orders with established quantities and purchase prices, as well as minimum purchase commitments, all made in the normal course of business. At December 31, 2017, our total purchase obligations were $21.0 million, of which $17.9 million will be due in 2018.
