Summary of Significant Accounting Policies | NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business Industrial Services of America, Inc. (a Florida corporation) and its subsidiaries ("ISA" or the "Company") purchases and sells ferrous and nonferrous materials at four Kentucky and Indiana locations. Additionally, ISA operates Pick.Pull.Save used automobile parts yard. All of these activities operate under the Company's Recycling Segment. During 2015, ISA sold substantially all of the Waste Services Segment assets. See Note 15 - Discontinued Operations for further information. Accordingly, as of December 4, 2015, the Company's operations are solely in the Recycling Segment. The Company's core business is now focused on the metal recycling industry. During 2016, the Company announced that the Company formed a special committee Also, on March 31, 2017, the Company entered into an amended credit facility with MidCap (see Note 3 - Long Term Debt and Notes Payable to Bank), which extended the maturity date of the Company's line of credit and increased the available borrowing capacity of the line of credit, subject to certain borrowing base restrictions and approvals. The Company also announced on October 4, 2016 that the Company and Algar mutually agreed to terminate the Management Agreement between them, pursuant to the Agreement to Terminate Management Services among the Company, Algar, and Sean Garber dated as of September 30, 2016. Effective September 30, 2016, Mr. Garber resigned from all positions with the Company, including as President. The Company's Response to 2015 and 2016 Commodity Markets and Liquidity Conditions During 2015, the Company's average selling price per unit of quantity decreased by 49.4% and 24.9% for ferrous and nonferrous material, respectively, compared to 2014. These decreases also led to significantly lower volumes of material available to the Company to buy and sell. Due to these deteriorating metals commodity market conditions, ISA took significant steps to improve liquidity and pay down debt during 2015 and 2016. Despite modest improvements in metal commodity markets during 2016, low prices combined with low volumes present a difficult ongoing metals recycling market . The Company took the below steps to address the challenging metal commodity market. On February 27, 2015, the Company closed on the sale of its Seymour, Indiana property. Also, in conjunction with this decision, the Company signed a lease, effective December 1, 2014, to lease a facility in the Seymour area. See Note 4 - Lease Commitments for further lease information and Note 10 - Related Party Transactions for further related party details. Proceeds were used to reduce debt and improve liquidity. On April 30, 2015, LK Property Investments, LLC ("LK Property"), an entity principally owned by Daniel M. Rifkin, CEO of MetalX LLC ("MetalX"), (a related party) a scrap metal recycling company headquartered in Waterloo, Indiana, and the principal owner of Recycling Capital Partners, LLC ("RCP") (a related party) purchased a 4.4 acre parcel of real estate located at 6709 Grade Lane, Louisville, KY from ISA Real Estate LLC, a wholly-owned subsidiary of the Company, for a purchase price of $1.0 million. The Company realized a loss of $102.0 thousand from this sale. Also on April 30, 2015, the Company entered into a lease agreement with LK Property for a portion of the 4.4 acre parcel. See Note 4 - Lease Commitments for further lease details. Proceeds were used to reduce debt and improve liquidity. On May 13, 2015, the Company announced the warm idle of the Company’s auto shredder. This action was in response to market conditions, primarily related to ferrous price volatility and lower ferrous volumes. Management will continue to monitor and analyze market conditions and to review the Company’s long-term options for its shredder and related downstream processing operation. The costs of idling were recognized in the 2015 financial statements. As a result of the continued operating losses from the shredder operations, management reviewed the carrying cost of the shredder, including the downstream processing system. The Company recognized an asset impairment charge of approximately $636.6 thousand related to the shredder’s downstream processing system. This charge was recorded in 2015 as an impairment charge on property and equipment within the cost of goods section in the accompanying consolidated statement of operations. As of the date of this report, the shredder remains idled. The Company continues to depreciate the assets associated with the shredder. Working capital, which would otherwise have been utilized in operating the shredder, was used to reduce debt and improve liquidity. In May 2015, ISA Real Estate, LLC sold to SG&D Ventures, LLC ("SG&D"), an entity owned by shareholders of Algar, Inc. ("Algar"), including Sean Garber, at that time the Company’s Vice Chairman of the Board and President, and the President of Algar, an approximately 1 $350.0 thousand. The purchase consideration consisted of $300.0 thousand in cash from the purchaser and a credit of $50.0 thousand against bonus compensation previously accrued but not paid to Algar as described in Note 10 - Related Party Transactions. The gain on sale of this asset was $1.1 thousand and was recognized during the second quarter of 2015. Proceeds were used to reduce debt and improve liquidity. On November 6, 2015, the Company entered into a Forbearance Agreement and Third Amendment to Credit Agreement (the “Forbearance Agreement”) by and among the Company, certain of the Company’s subsidiaries, and Wells Fargo Bank, National Association ("Wells Fargo"). The Forbearance Agreement amended the Credit Agreement to reduce the Maximum Revolver Amount from $15.0 million to $5.0 million. The Forbearance Agreement also amended the Credit Agreement Maturity Date to March 15, 2016 from June 13, 2019. The Forbearance Agreement increased the interest rate on the outstanding indebtedness by approximately 100 Pursuant to the terms of the Forbearance Agreement, Wells Fargo agreed that it would forbear, until the Forbearance Termination Date (as defined below), from exercising certain rights and remedies with respect to or arising out of the existence and continuation of certain stipulated events of default under the Credit Agreement between the loan parties and Wells Fargo (as amended by the First Amendment to Credit Agreement dated January 15, 2015, the Second Amendment to Credit Agreement dated January 22, 2015, and the Forbearance Agreement, the “Credit Agreement”). Under the Forbearance Agreement, the Forbearance Termination Date was the earlier to occur of (i) Wells Fargo’s election following the failure of the Loan Parties to satisfy any of the Forbearance Conditions, and (ii) March 15, 2016. See Note 3 - Long Term Debt and Notes Payable to Bank for further details. On December 4, 2015, the Company and WESSCO, LLC, a wholly owned subsidiary of ISA ("WESSCO"), entered into an Asset Purchase Agreement (the "Asset Purchase Agreement") with Compactor Rentals of America, LLC ("Compactor Rentals") pursuant to which the Company sold its “Waste Services Segment,” consisting of substantially all of the assets used in (i) the Company’s commercial, retail and industrial waste and recycling management services business which the Company operated under the name “Computerized Waste Systems” or “CWS,” and (ii) the Company’s equipment sales, rental and maintenance business for the commercial and industrial waste and recycling industry which the Company operated under the name “Waste Equipment Sales and Service Company" The Company received cash consideration at closing of $7.5 million, less $150.0 thousand retained by Compactor Rentals (the "Holdback"). In connection with the closing of the transaction, the Company entered into a transition services agreement with Compactor Rentals, pursuant to which the Company will provide certain services to Compactor Rentals until March 31, 2017 On April 1, 2016, the Company entered Amendment No. 1 to the Asset Purchase Agreement which extended the deadline for the Company to provide written notice if the Company objected to Compactor Rental’s calculation of the Holdback. On April 15, 2016, the Company entered into Amendment No. 2 to the Asset Purchase Agreement whereby the Company and Compactor Rentals agreed that the Holdback would be retained by Compactor Rentals based on a mutually-agreed upon calculation of working capital. Amendment No. 2 also detailed the parties’ agreement of the following: no indemnification claims would be made by Compactor Rentals arising out of certain matters; certain Compactor Rentals’ representatives did not have knowledge of any additional indemnification claims as of April 15, 2016; and the transition services agreement between the parties would be extended at no cost to Compactor Rentals through March 31, 2017. Compactor Rentals assumed certain liabilities relating to the Waste Services Segment, including but not limited to, current liabilities, warranty liabilities, and post-closing liabilities incurred in connection with transferred contracts The sale included substantially all of the assets of the Waste Services Segment including, but not limited to, current assets, accounts receivable, tangible personal property, certain leases, inventory, intellectual property, rights under transferred contracts, rights of action and all associated goodwill and other intangible assets associated with the transferred assets The Asset Purchase Agreement contains a restrictive covenant under which the Company is prohibited from competing with the Waste Services Segment for five See Note 15 - Discontinued Operations related to the sale of the Waste Services Segment. The Company used the proceeds from the transaction to pay transaction expenses, to repay in full the Company’s outstanding indebtedness with Bank of Kentucky, Inc., ("KY Bank") and to repay in full ISA’s term loan from Wells Fargo. The Company also used the proceeds to pay all outstanding amounts on ISA’s $5.0 million revolving line of credit with Wells Fargo which remained available following the closing. As of December 31, 2015, the revolving line of credit had an amount outstanding of approximately $19.7 thousand. On February 29, 2016, the Company entered into a Loan Agreement (the "2016 Loan") with MidCap Business Credit, LLC ("MidCap"). The 2016 Loan is secured by substantially all of the assets of the Company. Proceeds from this loan were used to pay transaction expenses and to pay off and close the remaining balance on the Wells Fargo revolving line of credit. On March 31 , 2017, the Company entered into an amendment to the 2016 Loan to increase the line of credit from $6.0 million to $8.0 million, subject to the satisfaction of certain borrowing base restrictions, and extend the maturity date to February 28, 2020. See Note 3 - Long Term Debt and Notes Payable to Bank for further details Liquidity Risk Factors The Company’s primary sources of liquidity during 2015 and 2016 were cash flows generated from asset sales, the idling of our auto shredder operation and the refinancing and availability of the Company's working line of credit. Notwithstanding the above, management believes it will have adequate liquidity for at least one year beyond the date this Form 10-K is issued. This determination is based on the following: improved operating results in recent months, operating and cash flow projections for 2017 and 2018, and the amended credit facility with MidCap which extends the maturity date to February 28, 2020 and increases the borrowing availability, subject to certain borrowing base restrictions and approvals as described in Note 3 - Long Term Debt and Notes Payables to Bank Revenue Recognition ISA records revenue for its recycling operations upon delivery of the related materials. Revenue for the equipment sales divisions was recorded upon delivery of the equipment to the customer. The Company provided installation and training on all equipment and it charged these costs to the customer, recording revenue in the period the service was provided. The Company was the middleman in the sale of the equipment and not a manufacturer. Any warranty was the responsibility of the manufacturer and therefore, no estimates were made for warranty obligations. Allowances for equipment returns were made on a case-by-case basis. Historically, returns of equipment were not material. See Note 15 - Discontinued Operations for further details. The Company's management services group provided customers with evaluation, management, monitoring, auditing and cost reduction consulting of customers’ non-hazardous solid waste removal activities. The Company recognized revenue related to the management aspects of these services when it delivered the services. The Company recorded revenue related to this activity on a gross basis because the Company was ultimately responsible for service delivery, had discretion over the selection of the specific service provided and the amounts to be charged, and was directly obligated to the subcontractor for the services provided. ISA was an independent contractor. If the Company discovered that third party service providers had not performed, either by auditing of the service provider invoices or communications from customers, then the service delivery dispute was resolved directly with the third party service supplier. Revenue from equipment rental was recognized monthly as earned. See Note 15 - Discontinued Operations for further details. Fair Value of Financial Instruments T he Company carries certain of its financial assets and liabilities at fair value on a recurring basis. These financial assets and liabilities are composed of cash and cash equivalents and derivative instruments (for part of 2015). Long-term debt is carried at cost, and the fair value is disclosed herein. In addition, the Company measures certain assets, such as long-lived assets, at fair value on a non-recurring basis to evaluate those assets for potential impairment. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date In accordance with applicable accounting standards, the Company categorizes its financial assets and liabilities into the following fair value hierarchy: Level 1 – Financial assets and liabilities with values based on unadjusted quoted prices for identical assets or liabilities in an active market. Examples of Level 1 financial instruments include active exchange-traded securities. Level 2 – Financial assets and liabilities with values based on quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Examples of Level 2 financial instruments include various types of interest-rate and commodity-based derivative instruments, and various types of fixed-income investment securities. Pricing models are utilized to estimate fair value for certain financial assets and liabilities categorized in Level 2. Level 3 – Financial assets and liabilities with values based on prices or valuation techniques that require inputs that are both unobservable in the market and significant to the overall fair value measurement. These inputs reflect management’s judgment about the assumptions that a market participant would use in pricing the asset or liability, and are based on the best available information, some of which is internally developed. When determining the fair value measurements for financial assets and liabilities carried at fair value on a recurring basis, the Company considers the principal or most advantageous market in which it would transact and consider assumptions that market participants would use when pricing the asset or liability. When possible, ISA looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, the Company looks to market observable data for similar assets and liabilities. Nevertheless, certain assets and liabilities are not actively traded in observable markets, and the Company uses alternative valuation techniques to derive fair value measurements. The Company uses the fair value methodology outlined in the related accounting standards to value the assets and liabilities for cash, debt and derivatives. All of our cash is defined as Level 1 and all our debt is defined as Level 2. In accordance with this guidance, the following tables represent our fair value hierarchy for Level 1 and Level 2 financial instruments, in thousands, at December 31, 2016 and 2015 Fair Value at Reporting Date Using Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs 2016 Level 1 Level 2 Total Assets: Cash and cash equivalents $ 526 $ — $ 526 Liabilities Current maturities of long term debt $ — $ (2,942 ) $ (2,942 ) Long term debt, related parties — ( 1,171 ) ( 1,171 ) Fair Value at Reporting Date Using Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs 2015 Level 1 Level 2 Total Assets: Cash and cash equivalents $ 642 $ — $ 642 Liabilities Long term debt $ — $ (20 ) $ (20 ) The Company had no transfers in or out of Levels 1 or 2 fair value measurements. We have had no activity in Level 3, fair value measurements for the years ended December 31, 2016 or 2015 except for an impairment of property and equipment charge of $636.6 thousand for the year ended December 31, 2015 Estimates In preparing the consolidated financial statements in conformity with generally accepted accounting principles in the United States of America ("GAAP"), management must make estimates and assumptions. These estimates and assumptions affect the amounts reported for assets, liabilities, revenues and expenses, as well as affecting the disclosures provided. Examples of estimates include the allowance for doubtful accounts, estimates of realizability of deferred income tax assets and liabilities, estimates of inventory balances and values, and estimates of stock option and warrant values. The Company also uses estimates when assessing fair values of assets and liabilities acquired in business acquisitions as well as any fair value and any related impairment charges related to the carrying value of inventory and machinery and equipment, and other long-lived assets. Despite Discontinued Operations Prior year financial statements have been recast to reflect the sale of the Company’s Waste Services Segment assets in the fourth quarter of 2015 in accordance with the Financial Accounting Standards Board Accounting Standards Codification 205-20-55 within discontinued operations. Results of discontinued operations are excluded from the accompanying Notes to Consolidated Financial Statements for all periods presented, unless otherwise noted. See Note 15 - Discontinued Operations. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Upon consolidation, all inter-company accounts, transactions and profits have been eliminated. Cash and Cash Equivalents Cash and cash equivalents includes cash in banks with original maturities of three months or less. Cash and cash equivalents are stated at cost which approximates fair value, which in the opinion of management, are subject to an insignificant risk of loss in value. The Company maintains cash balances in excess of federally insured limits. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable consists primarily of amounts due from customers from product and brokered sales. The allowance for doubtful accounts totaled $35.0 thousand and $35.0 thousand at December 31, 2016 and 2015, respectively. The determination of the allowance for doubtful accounts includes a number of factors, including the age of the balance, estimated settlement adjustments, past experience with the customer account, changes in collection patterns and general economic and industry conditions. Interest is not normally charged on receivables, nor is collateral for receivables normally required. Potential credit losses from significant customers could adversely affect results of operations or financial condition. While the Company believes the allowance for doubtful accounts is adequate, changes in economic conditions or any weakness in the steel and metals industry could adversely impact future earnings. In general, the Company considers accounts receivable past due which are 30 to 60 days after the invoice date. Losses are charged off to the allowance when it is deemed further collection efforts will not provide additional recoveries. Major Customer : The Company had sales to a major customer that totaled approximately 12.5% of net sales f or the year ended December 31, 2016 December 31, 2016 December 31, 2015 10 Inventories: The Company's inventories primarily consist of ferrous and non-ferrous scrap metals, and are valued at the lower of average purchased cost or net realizable value ("NRV") based on the specific scrap commodity. See Impact of Recently Issued Accounting Standards at the end of Note 1. Quantities of inventories are determined based on our inventory systems and are subject to periodic physical verification using estimation techniques including observation, weighing and other industry methods. The Company recognizes inventory impairment and related adjustments when the NRV, based upon current market pricing, falls below recorded value or when the estimated volume is less than the recorded volume of the inventory. The Company records the loss in cost of sales in the period during which the loss is identified Certain assumptions are made regarding future demand and net realizable value in order to assess whether inventory is properly recorded at the lower of cost or NRV. Assumptions are based on historical experience, current market conditions and remaining costs of processing (if any) and disposal. If the anticipated future selling prices of scrap metal and finished steel products should decline, the Company would re-assess the recorded NRV of the inventory and make any adjustments believed necessary in order to reduce the value of the inventory (and increase cost of sales) to the lower of cost or NRV. Management spent much of 2014 and early 2015 working to assess the Company's automobile shredder residue ("ASR") process. Significant process and strategy changes associated with the ASR process were made. These changes, combined with the significant metals market reduction in market demand and prices experienced in late 2014 and through 2015, caused management to perform a lower of cost-or-market assessment, which resulted in inventory write-downs of $1.3 million for the year ended of December 31, 2015. The Company did not have a lower of cost-or-NRV inventory write-down for the year ended December 31, 2016 . Some commodities are in saleable condition at acquisition. The Company purchases these commodities in small amounts until it has a truckload of material available for shipment. Some commodities are not in saleable condition at acquisition. These commodities must be shredded, torched or baled. ISA does not have work-in-process inventory that needs to be manufactured to become finished goods. The Company includes processing costs in inventory for all commodities by weight Inventories as of December 31, 2016 and 2015 consist of the following: December 31, 2016 Raw Materials Finished Goods Processing Costs Total (in thousands) Ferrous and non-ferrous materials $ 2,222 $ 805 $ 410 $ 3,437 December 31, 2015 Raw Materials Finished Goods Processing Costs Total (in thousands) Ferrous and non-ferrous materials $ 1,354 $ 652 $ 404 $ 2,410 Property and Equipment Property and equipment are stated at cost and depreciated on a straight-line basis over the estimated useful lives of the related property. Property and equipment, in thousands, as of December 31, 2016 and 2015 consist of the following: Life 2016 2015 Land $ 4,993 $ 4,993 Equipment and vehicles 1-10 years 26,606 25,363 Office equipment 1-7 years 1,624 1,624 Building and leasehold improvements 5-40 years 7,708 7,821 $ 40,931 $ 39,801 Less accumulated depreciation 27,863 25,649 $ 13,068 $ 14,152 Depreciation expense for the years ended December 31, 2016 and 2015 $2.3 million and $2.4 million, respectively. Of the $2.3 million of depreciation expense recognized in 2016 $ 2.2 $0.1 $2.4 million of depreciation expense recognized in 2015 $2.2 million was recorded in cost of sales, and $0.2 million was recorded in general and administrative expense. Certain Banking Expenses The Company has included certain banking costs relating to our loans and loan restructuring within interest expense. The loan fees amortization totaled $130.1 thousand and $242.4 thousand for the years ended December 31, 2016 and 2015, respectively. On November 6, 2015, the Company and Wells Fargo entered into a forbearance agreement that changed the maturity date of the debt related to these certain banking expenses to March 15, 2016. Additionally, on December Shipping and Handling Fees and Costs Shipping and handling charges incurred by the Company are included in cost of sales and shipping charges billed to the customer are included in revenues in the accompanying consolidated statements of operations. Advertising Expense Advertising costs are charged to expense in the period the costs are incurred. Advertising expense was $0.8 thousand and $2.4 thousand for the years ended December 31, 2016 and 2015 , respectively. Derivative and Hedging Activities The Company is exposed to market risk stemming from changes in metal commodity prices, and interest rates. In the normal course of business, the Company actively manages its exposure to interest rate risks by entering into various hedging transactions, authorized under established policies that place clear controls on these activities. Derivative financial instruments previously used consist of interest rate swap contracts. Derivative financial instruments are accounted for under the provisions of the FASB's authoritative guidance titled “ASC 815 - Derivatives and Hedging.” Under these standards, derivatives are carried on the balance sheet at fair value. The Company's interest rate swaps were designated as a cash flow hedge, and the effective portions of changes in the fair value of the derivatives were recorded as a component of other comprehensive income or loss and were recognized in the statement of operations when the hedged item affected earnings. Ineffective portions of changes in the fair value of cash flow hedges were recognized in gain or loss on derivative liabilities. Cash flows related to derivatives were included in operating activities. As of December 31, 2016 and 2015 The Company does not enter into any interest rate swap derivative instruments for trading purposes. The Company recognizes as an adjustment to interest expense the differential paid or received on interest rate swaps. The change in the fair value of the interest rate swap, which was established as an effective hedge, was included in other comprehensive income. The Company includes the required disclosures for interest rate swaps in Note 3 – Long Term Debt and Notes Payable to Bank. During 2016 2015 , we did not use derivative instruments in the form of commodity hedges to assist in managing our commodity price risk. We do not enter into any commodity hedges for trading purposes. Income Taxes Deferred income taxes are recorded to recognize the tax consequences on future years of differences between the tax basis of assets and liabilities and their carrying amounts for financial reporting purposes, referred to as “temporary differences,” and for net operating loss carry-forwards subject to an ongoing assessment of realizability. Deferred income taxes are measured by applying current tax laws. The Company uses the deferral method of accounting for available state tax credits relating to the purchase of the shredder equipment. The FASB has issued guidance, included in the ASC, related to the accounting for uncertainty in income taxes recognized in financial statements. The Company recognizes uncertain income tax positions using the "more-likely-than-not" approach as defined in the ASC. The amount recognized is subject to estimate and management’s judgment with respect to the most likely outcome for each uncertain tax position. The amount that is ultimately sustained for an individual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount recognized. The Company has no liability for uncertain tax positions recognized as of December 31, 2016 and 2015 . As a policy, the Company recognizes interest accrued related to unrecognized tax positions in interest expense and penalties in operating expenses. See also Note 7 - Income Taxes for additional information relating to income taxes. Earnings (Loss) Per Share Basic earnings (loss) per share are computed by dividing net income (loss) by the weighted average number of common shares outstanding during the year. Diluted earnings (loss) per share are computed by dividing net income (loss) by the weighted average number of common shares outstanding plus the dilutive effect of stock options and warrants. Accumulated Other Comprehensive Income (Loss) Comprehensive income (loss) is net income (loss) plus certain other items that are recorded directly to shareholders’ equity. Amounts included in accumulated other comprehensive loss for our derivative instruments are not recorded net of tax in 2015 due to the valuation allowance recorded. See Note 7 - Income Taxes for additional information relating to the valuation allowance. There are no amounts included in accumulated other comprehensive loss for derivative instruments in 2016. Stock Option Arrangements The Company has a Long Term Incentive Plan adopted in 2009 ("LTIP") under which it may grant equity awards for up to 2.4 million shares of common stock, which are reserved by the Board of Directors for issuance of equity awards. The Company provides compensation benefits by granting stock options and other share-based awards to employees and directors The exercise price of each option is equal to the market price of the Company's stock on the date of grant. The maximum term of the option is five years. The plan is accounted for based on FASB’s authoritative guidance titled "ASC 718 - Compensation - Stock Compensation. " The Company recognizes share-based compensation expense for the fair value of the awards, on the date granted, on a straight-line basis over their vesting term (service period). Compensation expense is recognized only for share-based payments expected to vest. The Company estimates forfeitures at the date of grant based on our historical experience and future expectations. The Company uses the grant date stock price to value the Company's restricted stock units. The fair value of each restricted stock unit is estimated on the date of grant. The Company uses the Modified Black-Scholes-Merton option-pricing model to value the Company's stock options for each employee stock option award. Using these option pricing models, the fair value of each stock option award is estimated on the date of grant There are two significant inputs into the stock option pricing models: expected volatility and expected term. The Company estimates expected volatility based on traded option volatility of the Company's stock over a term equal to the expected term of the option granted. The expected term of stock option awards granted is derived from historical exercise experience under the Company's stock option plans and represents the period of time that stock option awards granted are expected to be outstanding. The expected term assumption incorporates the contractual term of an option grant, as well as the vesting period of an award. The risk-free interest rate is based on the implied yield on a U.S. Treasury constant maturity with a remaining term equal to the expected term of the option granted. The assumptions used in calculating the fair value of stock-based payment awards represent management's best estimates, but these estimates involve inherent uncertainties and the application of management's judgment. As a result, if factors change and different assumptions are used, stock-based compensation expense could be ma |
