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 of independent board members to evaluate various growth and strategic options. During the first quarter of 2017, the special committee concluded its work and reported to the Board. The Board accepted the special committee's recommendation to focus on returning the core recycling business to profitability. The Company intends to do this by increasing efficiencies and productivity, which included the commercial restart of the Company's auto shredder in the second quarter of 2017. The Company operates the auto shredder in the normal course of business subject to market conditions and operating needs. ISA will also evaluate other various options and remain alert for possible strategic partnerships, joint ventures and mergers/acquisitions.

On March 26, 2018, the Board appointed Todd L. Phillips as Chief Executive Officer. See Note 7 – Share-Based Compensation and Other Compensation Agreements. Mr. Phillips has been the Company's Chief Financial Officer since December 31, 2014 and President since September 30, 2016 and will continue to serve in these roles.

Liquidity

During the first quarter of 2017, the Company amended and extended its working capital line of credit which extended the contractual maturity date to February 28, 2020 and increased the borrowing availability. See Note 3 – Long-Term Debt and Notes Payable to Bank for discussion of loan arrangements with MidCap Business Credit LLC ("MidCap"). The Company expects operating cash flow and borrowings under its working capital line of credit to be sufficient to meet its ongoing obligations.

The borrowings under the working capital line of credit are classified as short-term obligations under GAAP as the agreement with the lender contains a subjective acceleration clause and requires the Company to maintain a lockbox arrangement with the lender. However, the contractual maturity date of the revolver is February 28, 2020.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. The Accounting Standards Codification ("ASC") as produced by the Financial Accounting Standards Board ("FASB") is the sole source of authoritative GAAP. In the opinion of management of the Company, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position at March 31, 2018, and the results of operations and changes in cash flows for the quarters ended March 31, 2018 and 2017. Results of operations for the period ended March 31, 2018 are not necessarily indicative of the results that may be expected for the entire year. Additional information, including the audited December 31, 2017 consolidated financial statements and the Summary of Significant Accounting Policies, is included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017, on file with the Securities and Exchange Commission.

Estimates

In preparing the consolidated financial statements in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X, 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 deferred income tax assets and liabilities, estimates of inventory balances, 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 the Company’s intention to establish accurate estimates and use reasonable assumptions, actual results may differ from these estimates.

Principles of Consolidation

The Condensed 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.

Reclassifications

The Company has reclassified certain items within the accompanying Condensed Consolidated Financial Statements and Notes to Condensed Consolidated Financial Statements for the prior year in order to be comparable with the current presentation. These reclassifications had no effect on previously reported net income (loss) or shareholders' equity.

Revenue Recognition

The Company's revenue is primarily generated from contracts with customers. The Company notes there have been no credit losses recorded on any receivables or contract assets arising from contracts with customers for the three month periods ended March 31, 2018 and 2017. The Company elects to use the practical expedient as it relates to significant financing components as the Company expects, at the contract inception, that the period between when the Company transfers a promised good and when the customer pays for that good will be one year or less.

Ferrous and nonferrous revenue

Ferrous and non-ferrous contracts contain one performance obligation which consists of the shipment of a stated quantity of a stated product to be delivered within a stated time frame. Ferrous and non-ferrous revenue contracts are primarily short term contracts, typically completed within 30 days. Ferrous and non-ferrous transaction prices are stated in the contract with no variable considerations present. As ferrous and non-ferrous contracts contain one performance obligation, the total transaction price is allocated to the shipment of materials. When multiple loads are included in one contract, the stated price per gross tons is applied to the shipment weight in order to determine transaction price. Ferrous and non-ferrous revenue is recognized when the Company satisfies the shipment of materials per the contract. The shipment and delivery of material typically occurs on the same day. No contract assets or contract liabilities were recognized for the three month periods ended March 31, 2018 and 2017.

Revenue from auto parts operations and other revenue

Revenue from auto parts primarily consists of individual transactions by customers who enter the Company’s premises and purchase auto parts by cash or credit card. Related to these sales, a customer may be charged a core charge. The customer has 30 days to return the core and receive a refund of the core charge. Additionally, customers have the option to separately purchase a warranty related to certain goods purchased. Total core charges and warranty sales are immaterial in aggregate accounting for less than 1% of revenue from auto parts operations and other revenue. Sale prices, core charges and warranties are tracked separately and recognized as revenue when the purchase is completed. No contract assets or contract liabilities were recognized for the three month periods ended March 31, 2018 and 2017.

Fair Value

The 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. 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 considers 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 and debt. 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 table represents our fair value hierarchy for Level 1 and Level 2 financial instruments at March 31, 2018 and December 31, 2017 (in thousands):


	Fair Value at Reporting Date Using
March 31, 2018:	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs
Assets:	Level 1		Level 2			Total
Cash and cash equivalents	$	880	$	—		$	880
Liabilities:
Current maturities of long-term debt	$	—	$	(5,874	)	$	(5,874	)
Long-term debt, related parties		—		(1,335	)		(1,335	)

	Fair Value at Reporting Date Using
December 31, 2017:	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs
Assets:	Level 1		Level 2			Total
Cash and cash equivalents	$	841	$	—		$	841
Liabilities:
Current maturities of long-term debt	$	—	$	(5,018	)	$	(5,018	)
Long-term debt, related parties		—		(1,331	)		(1,331	)

The Company had no transfers in or out of Levels 1 or 2 fair value measurements, and no activity in Level 3 fair value measurements for the three month periods ended March 31, 2018 or 2017.

Common Stock and Share-based Compensation 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 the Company's 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. See Note 7 – Share-Based Compensation and Other Compensation Agreements. 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 materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate, and only recognize expense for those shares expected to vest. If the actual forfeiture rate is materially different from the estimate, the stock-based compensation expense could be significantly different from what was recorded in the current period.

Treasury shares or new shares are issued for exercised options. The Company does not expect to repurchase any additional shares within the following annual period to accommodate the exercise of outstanding stock options.

Under the LTIP, the Company may grant any of these types of awards: non-qualified and incentive stock options; stock appreciation rights; and other stock awards including stock units, restricted stock units, performance shares, performance units and restricted stock. The performance goals that the Company may use for such awards will be based on any one or more of the following performance measures: cash flow; earnings; earnings per share; market value added or economic value added; profits; return on assets; return on equity; return on investment; revenues; stock price; or total shareholder return.

The LTIP is administered by a committee selected by the Board consisting of two or more outside members of the Board. The Committee may grant one or more awards to our employees, including our officers, our directors and consultants, and will determine the specific employees who will receive awards under the plan and the type and amount of any such awards. A participant who receives shares of stock awarded under the plan must hold those shares for six months before the participant may dispose of such shares.

Subsequent Events

The Company has evaluated the period from March 31, 2018 through the date the financial statements herein were issued for subsequent events requiring recognition or disclosure in the financial statements and identified the following:

The Company filed an insurance claim related to roofs on certain of its buildings due to weather related damage and received an initial payment in the third quarter of 2016. Subsequent to March 31, 2018, the Company received an additional payment from its insurance company for $659.9 thousand. This amount is gross of certain related fees and expenses. The Company will record the gain in the second quarter of 2018.

Impact of Recently Issued Accounting Standards

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The amendments in ASU 2014-09 affect any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. On January 1, 2018, the Company adopted ASU 2014-09 using the retrospective approach. The Company noted no financial impact on the Condensed Consolidated Financial Statements as a result of the adoption of this amended guidance. In addition, the adoption of this new accounting standard resulted in increased disclosure, including qualitative and quantitative disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. See the Revenue Recognition section of Note 1 – Summary of Significant Accounting Policies and General for additional information.

In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, which requires that deferred tax assets and liabilities be classified as noncurrent on the consolidated balance sheet. ASU 2015-17 was effective for annual periods beginning after December 15, 2016, including interim periods within those annual periods. Upon adoption, ASU 2015-17 may be applied either prospectively or retrospectively. The Company adopted the standard in the first quarter of 2017 and noted no material impact from the adoption on the Condensed Consolidated Financial Statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases, to improve financial reporting about leasing transactions. This ASU will require organizations that lease assets (“lessees”) to recognize a lease liability and a right-of-use asset on its balance sheet for all leases with terms of more than twelve months. A lease liability is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis and a right-of-use asset represents the lessee’s right to use, or control use of, a specified asset for the lease term. The amendments in this ASU simplify the accounting for sale and leaseback transactions. This ASU leaves the accounting for the organizations that own the leased assets largely unchanged except for targeted improvements to align it with the lessee accounting model and Topic 606, Revenue from Contracts with Customers.

The amendments in ASU 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is evaluating the potential impact of ASU 2016-02 on the Condensed Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, which provides guidance to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. The Company is evaluating the potential impact of ASU 2016-13 on the Condensed Consolidated Financial Statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, Classification of Certain Cash Receipts and Cash Payments, which provides guidance on eight specific cash flow issues. ASU 2016-15 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Upon adoption, ASU 2016-15 should be applied retrospectively. The Company is evaluating the potential impact of ASU 2016-15 on the Condensed Consolidated Financial Statements, but does not expect a material impact from the adoption of ASU 2016-15 on the Condensed Consolidated Financial Statements.

No other new accounting pronouncements issued or effective during the reporting period had, or is expected to have, a material impact on our Condensed Consolidated Financial Statements.
