Accounting Policies [Abstract]
Environmental Costs	Our operations are subject to various environmental statutes and regulations, including laws and regulations addressing materials used in the processing of our products. In addition, certain of our operations are subject to federal, state and local environmental laws and regulations that impose limitations on the discharge of pollutants into the air and water and establish standards for the treatment, storage and disposal of solid and hazardous wastes. Failure to maintain or achieve compliance with these laws and regulations or with the permits required for our operations could result in substantial operating costs and capital expenditures, in addition to fines and civil or criminal sanctions, third party claims for property damage or personal injury, cleanup costs or temporary or permanent discontinuance of operations. Certain of our facilities have been in operation for many years and, over time, we and other predecessor operators of these facilities have generated, used, handled and disposed of hazardous and other regulated wastes. Environmental liabilities could exist, including cleanup obligations at these facilities or at off-site locations where we disposed of materials from our operations, which could result in future expenditures that we cannot currently quantify and which could reduce our profits. Any environmental regulatory liability relating to our operations is generally borne by the customers with whom we contract and the service providers in their capacity as transporters, disposers and recyclers. Our policy is to use our best efforts to secure indemnification for environmental liability from our customers and service providers. ISA records liabilities for remediation and restoration costs related to past activities when our obligation is probable and the costs can be reasonably estimated. Costs of future expenditures for environmental remediation are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable. Costs of ongoing compliance activities related to current operations are expensed as incurred.
Revenue Recognition	Revenue Recognition: ISA records revenue for its recycling and equipment sales divisions upon delivery of the related materials and equipment to the customer. We provide installation and training on all equipment and we charge these costs to the customer, recording revenue in the period we provide the service. We are the middleman in the sale of the equipment and not a manufacturer. Any warranty is the responsibility of the manufacturer and therefore we make no estimates for warranty obligations. Allowances for equipment returns are made on a case-by-case basis. Historically, returns of equipment have not been material. Our management services group provides our customers with evaluation, management, monitoring, auditing and cost reduction of our customers’ non-hazardous solid waste removal activities. We recognize revenue related to the management aspects of these services when we deliver the services. We record revenue related to this activity on a gross basis because we are ultimately responsible for service delivery, have discretion over the selection of the specific service provided and the amounts to be charged, and are directly obligated to the subcontractor for the services provided. We are an independent contractor. If we discover that third party service providers have not performed, either by auditing of the service provider invoices or communications from our customers, we then resolve the service delivery dispute directly with the third party service supplier. We record sales-type leases at the net present value of future minimum lease payments. Interest income related to the lease is recognized over the life of the lease. At the inception of the lease, any difference between the net present value of future cash flows and the basis of the leased asset (carrying value plus initial direct costs, less present value of any residual) is recorded as a gain or loss.
Fair Value of Financial Instruments	Fair Value of Financial Instruments: We estimate the fair value of our financial instruments using relevant market information and other assumptions. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, prepayments and other factors. Changes in assumptions or market conditions could significantly affect these estimates. As of December 31, 2012, the estimated fair value of our financial instruments approximated book value. The fair value of our debt approximates its carrying value because the majority of our debt bears a floating rate of interest based on the LIBOR rate. There is no readily available market by which to determine fair value of our fixed term debt; however, based on existing interest rates and prevailing rates as of each year end, we have determined that the fair value of our fixed rate debt approximates book value. We carry certain of our 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. Long-term debt is carried at cost, and the fair value is disclosed herein. In addition, we measure certain assets, such as goodwill and other 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, we categorize our 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 equity securities and certain U.S. government 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 commercial paper purchased from the State Street-administered asset-backed commercial paper conduits, 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. Examples of level 3 financial instruments include certain corporate debt with little or no market activity and a resulting lack of price transparency. When determining the fair value measurements for financial assets and liabilities carried at fair value on a recurring basis, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability. When possible, we look to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, we look to market observable data for similar assets and liabilities. Nevertheless, certain assets and liabilities are not actively traded in observable markets, and we use alternative valuation techniques to derive fair value measurements. We use the fair value methodology outlined in the related accounting standard to value the assets and liabilities for cash, debt and derivatives. All of our cash is defined as Level 1 and all our debt and derivative contracts are defined as Level 2
Estimates	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 associated with annual goodwill impairment tests, estimates of deferred income tax assets and liabilities, estimates of inventory balances, and estimates of stock option 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 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	Principles of Consolidation: The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, ISA Indiana, Inc., ISA Recycling, LLC, Industrial Logistics, and ISA Alloys. Upon consolidation, all inter-company accounts, transactions and profits have been eliminated.
Common Control	Common Control: We conduct significant levels of business with K&R, LLC (“K&R”), which is owned by ISA’s chief executive officer and principal shareholder (see Note 6 - "Related Party Transactions"). Because these entities are under common control, our operating results or our financial position may be materially different from those that would have been obtained if the entities were autonomous.
Reclassifications	Reclassifications: We have reclassified certain income statement items within the accompanying Consolidated Financial Statements and Notes to Consolidated Financial Statements for the prior years and prior quarters in order to be comparable with the current presentation. These reclassifications had no effect on previously reported income (loss).
Cash and Cash Equivalents	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. We maintain a cash account on deposit with BB&T which serves as collateral for our interest rate swap agreements. This compensating balance arrangement is verbal only and does not legally restrict the use of these funds.
Accounts Receivable and Allowance for Doubtful Accounts	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 $100.0 thousand at December 31, 2012 and December 31, 2011. Our determination of the allowance for doubtful accounts includes a number of factors, including the age of the balance, past experience with the customer account, changes in collection patterns and general economic and industry conditions. Interest is not normally charged on receivables nor do we normally require collateral for receivables. Potential credit losses from our significant customers could adversely affect our results of operations or financial condition. While we believe our allowance for doubtful accounts is adequate, changes in economic conditions or any weakness in the steel and metals industry could adversely impact our future earnings. In general, we consider accounts receivable past due which are 30 to 60 days after the invoice date. We charge off losses to the allowance when we deem further collection efforts will not provide additional recoveries.
Major Customer	Major Customer: North American Stainless ("NAS") is a major customer in our Recycling segment. Sales to NAS equaled 41.2% of our consolidated revenue in 2012, and 44.4% of our consolidated revenue in 2011, and the loss of NAS would have a material adverse effect on our financial statements.
Inventories	Inventories: Our inventories primarily consist of ferrous and non-ferrous scrap metals, including stainless steel, and fiber scrap and are valued at the lower of average purchased cost or market based on the specific scrap commodity. 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. We recognize inventory impairment when the market value, based upon current market pricing, falls below recorded value or when the estimated volume is less than the recorded volume of inventory. We record the loss in cost of goods sold in the period during which we identified the loss. We make certain assumptions regarding future demand and net realizable value in order to assess whether inventory is properly recorded at the lower of cost or market. We base our assumptions on historical experience, current market conditions and current replacement costs. If the anticipated future selling prices of scrap metal and finished steel products should decline, we would re-assess the recorded net realizable value of our inventory and make any adjustments we feel necessary in order to reduce the value of our inventory (and increase cost of goods sold) to the lower of cost or market. In the third quarter of 2011, demand and prices for inventory decreased due to reduced demand for stainless steel arising from weakening economic conditions, which led to a reduction in stainless steel sales volumes and average stainless steel selling prices. In addition, continued weak demand and the impact of declines in anticipated future selling prices which outpaced the decline in inventory costs, resulted in ISA recording a net realizable value (“NRV”) inventory write-down of $3.4 million in this quarter. No such write-down was necessary in 2012. Some commodities are in saleable condition at acquisition. We purchase these commodities in small amounts until we have a truckload of material available for shipment. Some commodities are not in saleable condition at acquisition. These commodities must be torched, shredded or baled. We do not have work-in-process inventory that needs to be manufactured to become finished goods. We include processing costs in inventory for all commodities by gross ton. Inventory also includes all types of industrial waste handling equipment and machinery held for resale such as compactors, balers, and containers, which are valued based on cost. Replacement parts included in inventory are depreciated over a one-year life and are used by the Company within the one-year period as these parts wear out quickly due to the high-volume and intensity of the shredder function. Other inventory includes cardboard, fuel, and baling wire.
Property and Equipment	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. Assets under capital lease obligations would be amortized over the term of the capital lease. A typical term of our rental equipment leases is 5 years. The revenue stream is based on monthly usage and recognized in the month of usage. We record purchased rental equipment, including all installation and freight charges, as a fixed asset. We are typically responsible for all repairs and maintenance expenses on rental equipment.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets: Goodwill is the excess of cost over the fair value of the net assets of businesses acquired. Goodwill and certain intangible assets are no longer amortized but are assessed at least annually for impairment with any such impairment recognized in the period identified. We perform our goodwill impairment test at least annually at December 31, unless there is a triggering event, in which case a test would be performed at the time that such triggering event occurs. We test for goodwill impairment using a two-step process and at the level of the recycling reporting units to which all the goodwill is related in accordance with ASC Topic 350 - Intangibles-Goodwill and Other. In the first step, we determine whether to impair goodwill by comparing the fair value of the recycling reporting unit as a whole (the present value of expected cash flows) to its carrying value including goodwill or by obtaining a valuation from an outside source. A reporting unit is an operating segment or one level below an operating segment (referred to as a "component"). A component is considered a reporting unit for purposes of goodwill testing if the component constitutes a business for which discrete financial information is available and segment management regularly reviews the operating results of that component. We have identified two reporting units, and we obtained a valuation from an outside source. If necessary, the second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination.
Intangibles	Intangibles: Purchased intangible assets are initially recorded at cost and finite life intangible assets are amortized over their useful economic lives on a straight line basis. Intangible assets having indefinite lives and intangible assets that are not yet ready for use are not amortized and are reviewed annually for impairment as required by the FASB's ASC. Intangible assets are considered to have indefinite lives when, based on an analysis of all of the relevant factors, there is no foreseeable limit to the period over which the asset is expected to generate cash flows for the Company. The factors considered in making this determination include the existence of contractual rights for unlimited terms and the life cycles of the products and processes that depend on the asset.
Advertising Expense	Advertising Expense: Advertising costs are charged to expense in the period the costs are incurred.
Derivative and Hedging Activities	Derivative and Hedging Activities: We are exposed to market risk stemming from changes in metal commodity prices, specifically nickel, and interest rates. In the normal course of business, we actively manage our exposure to these market risks by entering into various hedging transactions, authorized under established policies that place clear controls on these activities. These transactions utilize exchange traded derivatives or over-the-counter derivatives with investment grade counter-parties. Derivative financial instruments currently used by us consist of commodity futures, options and swap contracts. Derivative financial instruments are accounted for under the provisions of the FASB's authoritative guidance titled “ASC 815 - Derivative and Hedging.” Under these standards, derivatives are carried on the balance sheet at fair value. If the derivative is designated as a fair value hedge, such as our commodity hedges, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, such as our interest rate swaps, the effective portions of changes in the fair value of the derivatives are recorded as a component of other comprehensive income or loss and are recognized in the statement of operations when the hedged item affects earnings. If the derivative is not designated as a hedge, changes in the fair value are recognized in other income or expense. Ineffective portions of changes in the fair value of cash flow hedges are also recognized in gain or loss on derivative liabilities. Cash flows related to derivatives are included in operating activities. Beginning in October 2008, we began to utilize derivative instruments in the form of interest rate swaps to assist in managing our interest rate risk. We do not enter into any interest rate swap derivative instruments for trading purposes. We recognize as an adjustment to interest expense the differential paid or received on interest rate swaps. We include in other comprehensive income the change in the fair value of the interest rate swap, which is established as an effective hedge. We include the required disclosures for interest rate swaps in Note 3 – “Notes Payable to Bank” of our Notes to Consolidated Financial Statements. Beginning in July 2012, we began to utilize 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. We include the gain or loss on the hedged items and the offsetting loss or gain on the related commodity hedge in cost of goods sold. We assess the effectiveness of a commodity hedge contract based on changes in the contract's fair value. The changes in the market value of such contracts have historically been, and are expected to continue to be, highly effective at offsetting changes in the price of the hedged items. The amounts representing the ineffectiveness of these hedges are not expected to be significant.
Income Taxes	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. We use 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 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 uncertain tax positions recognized as of December 31, 2012 and 2011. As a policy, the Company recognizes interest accrued related to unrecognized tax positions in interest expense and penalties in operating expenses.
Earnings Per Share	Earnings Per Share: Basic earnings per share are computed by dividing net income by the weighted average number of common shares outstanding during the year. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding plus the dilutive effect of stock options.
Stock Option Plans	Stock Option Plans: We have an employee stock option plan under which we may grant options for up to 2.4 million shares of common stock, which are reserved by the board of directors for issuance of stock options. We provide compensation benefits by granting stock options to employees and directors. The exercise price of each option is equal to the market price of our stock on the date of grant. The maximum term of the option is five years. We account for this plan based on FASB’s authoritative guidance titled "ASC 718 - Compensation - Stock Compensation." We recognize share-based compensation expense for the fair value of the awards, as estimated using the Modified Black-Scholes-Merton Model, on the date granted on a straight-line basis over their vesting term. Compensation expense is recognized only for share-based payments expected to vest. We estimate forfeitures at the date of grant based on our historical experience and future expectations. There are two significant inputs into the Modified Black-Scholes-Merton option-pricing model: expected volatility and expected term. We estimate expected volatility based on traded option volatility of our 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 our long-term incentive plan and represents the period of time that stock option awards granted are expected to be outstanding. 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 we use different assumptions, stock-based compensation expense could be materially different in the future. In addition, we are required to estimate the expected forfeiture rate, and only recognize expense for those shares expected to vest. If our actual forfeiture rate is materially different from its estimate, the stock-based compensation expense could be significantly different from what we have recorded in the current period.
Impact of Recently Issued Accounting Standards	Impact of Recently Issued Accounting Standards: In September 2011, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2011-08, an amendment to Topic 350, Intangibles—Goodwill and Other, which simplifies how entities test goodwill for impairment. Previous guidance under Topic 350 required an entity to test goodwill for impairment using a two-step process on at least an annual basis. First, the fair value of a reporting unit was calculated and compared to its carrying amount, including goodwill. Second, if the fair value of a reporting unit was less than its carrying amount, the amount of impairment loss, if any, was required to be measured. Under the amendments in this update, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads the entity to determine that it is more likely than not that its fair value is less than its carrying amount. If after assessing the totality of events or circumstances, an entity determines that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then the two-step impairment test is unnecessary. If the entity concludes otherwise, then it is required to test goodwill for impairment under the two-step process as described under paragraphs 350-20-35-4 and 350-20-35-9 under Topic 350. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, the quarter ending March 31, 2012 for us, and early adoption was permitted. The adoption of ASU 2011-08 did not have a material impact on our Condensed Consolidated Financial Statements. In June 2011, the FASB issued ASU 2011-05, which is an update to Topic 220, “Comprehensive Income.” This update eliminates the option of presenting the components of other comprehensive income as part of the statement of changes in stockholders’ equity, requires consecutive presentation of the statement of net income and other comprehensive income and requires reclassification adjustments from other comprehensive income to net income to be shown on the financial statements. ASU 2011-05 is effective for all interim and annual reporting periods beginning after December 15, 2011, the quarter ending March 31, 2012 for us. However, in December 2011, the FASB issued ASU 2011-12, which has deferred the specific requirement within ASU 2011-05 to present on the face of the financial statements items that are reclassified from accumulated other comprehensive income to net income separately with their respective components of net income and other comprehensive income. Entities should continue to report reclassifications out of accumulated comprehensive income consistent with the presentation requirements in effect before ASU 2011-05. As ASU No. 2011-05 relates only to the presentation of Comprehensive Income, the adoption of such did not have a material impact on our Condensed Consolidated Financial Statements. In May 2011, the FASB issued ASU 2011-04, which is an update to Topic 820, “Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”)." The amendments in this ASU generally represent clarification of Topic 820, but also include instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed. This update results in common principles and requirements for measuring fair value and for disclosing information about fair value measurements in accordance with GAAP and IFRS. The amendments are effective for interim and annual periods beginning after December 15, 2011, the quarter ending March 31, 2012 for us, and are to be applied prospectively. Early application was not permitted. The adoption of ASU 2011-04 did not have a material impact on our Condensed Consolidated Financial Statements.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2012

Our operations are subject to various environmental statutes and regulations, including laws and regulations addressing materials used in the processing of our products. In addition, certain of our operations are subject to federal, state and local environmental laws and regulations that impose limitations on the discharge of pollutants into the air and water and establish standards for the treatment, storage and disposal of solid and hazardous wastes. Failure to maintain or achieve compliance with these laws and regulations or with the permits required for our operations could result in substantial operating costs and capital expenditures, in addition to fines and civil or criminal sanctions, third party claims for property damage or personal injury, cleanup costs or temporary or permanent discontinuance of operations. Certain of our facilities have been in operation for many years and, over time, we and other predecessor operators of these facilities have generated, used, handled and disposed of hazardous and other regulated wastes. Environmental liabilities could exist, including cleanup obligations at these facilities or at off-site locations where we disposed of materials from our operations, which could result in future expenditures that we cannot currently quantify and which could reduce our profits. Any environmental regulatory liability relating to our operations is generally borne by the customers with whom we contract and the service providers in their capacity as transporters, disposers and recyclers. Our policy is to use our best efforts to secure indemnification for environmental liability from our customers and service providers. ISA records liabilities for remediation and restoration costs related to past activities when our obligation is probable and the costs can be reasonably estimated. Costs of future expenditures for environmental remediation are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable. Costs of ongoing compliance activities related to current operations are expensed as incurred.

Revenue Recognition: ISA records revenue for its recycling and equipment sales divisions upon delivery of the related materials and equipment to the customer. We provide installation and training on all equipment and we charge these costs to the customer, recording revenue in the period we provide the service. We are the middleman in the sale of the equipment and not a manufacturer. Any warranty is the responsibility of the manufacturer and therefore we make no estimates for warranty obligations. Allowances for equipment returns are made on a case-by-case basis. Historically, returns of equipment have not been material.

Our management services group provides our customers with evaluation, management, monitoring, auditing and cost reduction of our customers’ non-hazardous solid waste removal activities. We recognize revenue related to the management aspects of these services when we deliver the services. We record revenue related to this activity on a gross basis because we are ultimately responsible for service delivery, have discretion over the selection of the specific service provided and the amounts to be charged, and are directly obligated to the subcontractor for the services provided. We are an independent contractor. If we discover that third party service providers have not performed, either by auditing of the service provider invoices or communications from our customers, we then resolve the service delivery dispute directly with the third party service supplier.

We record sales-type leases at the net present value of future minimum lease payments. Interest income related to the lease is recognized over the life of the lease. At the inception of the lease, any difference between the net present value of future cash flows and the basis of the leased asset (carrying value plus initial direct costs, less present value of any residual) is recorded as a gain or loss.

Fair Value of Financial Instruments

Fair Value of Financial Instruments: We estimate the fair value of our financial instruments using relevant market information and other assumptions. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, prepayments and other factors. Changes in assumptions or market conditions could significantly affect these estimates. As of December 31, 2012, the estimated fair value of our financial instruments approximated book value. The fair value of our debt approximates its carrying value because the majority of our debt bears a floating rate of interest based on the LIBOR rate. There is no readily available market by which to determine fair value of our fixed term debt; however, based on existing interest rates and prevailing rates as of each year end, we have determined that the fair value of our fixed rate debt approximates book value.

We carry certain of our 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. Long-term debt is carried at cost, and the fair value is disclosed herein. In addition, we measure certain assets, such as goodwill and other 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, we categorize our 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 equity securities and certain U.S. government 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 commercial paper purchased from the State Street-administered asset-backed commercial paper conduits, 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. Examples of level 3 financial instruments include certain corporate debt with little or no market activity and a resulting lack of price transparency.

Estimates

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 associated with annual goodwill impairment tests, estimates of deferred income tax assets and liabilities, estimates of inventory balances, and estimates of stock option 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 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

Principles of Consolidation: The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, ISA Indiana, Inc., ISA Recycling, LLC, Industrial Logistics, and ISA Alloys. Upon consolidation, all inter-company accounts, transactions and profits have been eliminated.

Common Control

Common Control: We conduct significant levels of business with K&R, LLC (“K&R”), which is owned by ISA’s chief executive officer and principal shareholder (see Note 6 - "Related Party Transactions"). Because these entities are under common control, our operating results or our financial position may be materially different from those that would have been obtained if the entities were autonomous.

Reclassifications

Reclassifications: We have reclassified certain income statement items within the accompanying Consolidated Financial Statements and Notes to Consolidated Financial Statements for the prior years and prior quarters in order to be comparable with the current presentation. These reclassifications had no effect on previously reported income (loss).

Cash and Cash Equivalents

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. We maintain a cash account on deposit with BB&T which serves as collateral for our interest rate swap agreements. This compensating balance arrangement is verbal only and does not legally restrict the use of these funds.

Accounts Receivable and Allowance for Doubtful Accounts

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 $100.0 thousand at December 31, 2012 and December 31, 2011. Our determination of the allowance for doubtful accounts includes a number of factors, including the age of the balance, past experience with the customer account, changes in collection patterns and general economic and industry conditions. Interest is not normally charged on receivables nor do we normally require collateral for receivables. Potential credit losses from our significant customers could adversely affect our results of operations or financial condition. While we believe our allowance for doubtful accounts is adequate, changes in economic conditions or any weakness in the steel and metals industry could adversely impact our future earnings. In general, we consider accounts receivable past due which are 30 to 60 days after the invoice date. We charge off losses to the allowance when we deem further collection efforts will not provide additional recoveries.

Major Customer: North American Stainless ("NAS") is a major customer in our Recycling segment. Sales to NAS equaled 41.2% of our consolidated revenue in 2012, and 44.4% of our consolidated revenue in 2011, and the loss of NAS would have a material adverse effect on our financial statements.

Inventories

Inventories: Our inventories primarily consist of ferrous and non-ferrous scrap metals, including stainless steel, and fiber scrap and are valued at the lower of average purchased cost or market based on the specific scrap commodity. 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. We recognize inventory impairment when the market value, based upon current market pricing, falls below recorded value or when the estimated volume is less than the recorded volume of inventory. We record the loss in cost of goods sold in the period during which we identified the loss.

We make certain assumptions regarding future demand and net realizable value in order to assess whether inventory is properly recorded at the lower of cost or market. We base our assumptions on historical experience, current market conditions and current replacement costs. If the anticipated future selling prices of scrap metal and finished steel products should decline, we would re-assess the recorded net realizable value of our inventory and make any adjustments we feel necessary in order to reduce the value of our inventory (and increase cost of goods sold) to the lower of cost or market. In the third quarter of 2011, demand and prices for inventory decreased due to reduced demand for stainless steel arising from weakening economic conditions, which led to a reduction in stainless steel sales volumes and average stainless steel selling prices. In addition, continued weak demand and the impact of declines in anticipated future selling prices which outpaced the decline in inventory costs, resulted in ISA recording a net realizable value (“NRV”) inventory write-down of $3.4 million in this quarter. No such write-down was necessary in 2012.

Some commodities are in saleable condition at acquisition. We purchase these commodities in small amounts until we have a truckload of material available for shipment. Some commodities are not in saleable condition at acquisition. These commodities must be torched, shredded or baled. We do not have work-in-process inventory that needs to be manufactured to become finished goods. We include processing costs in inventory for all commodities by gross ton.

Inventory also includes all types of industrial waste handling equipment and machinery held for resale such as compactors, balers, and containers, which are valued based on cost. Replacement parts included in inventory are depreciated over a one-year life and are used by the Company within the one-year period as these parts wear out quickly due to the high-volume and intensity of the shredder function. Other inventory includes cardboard, fuel, and baling wire.

Property and Equipment

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. Assets under capital lease obligations would be amortized over the term of the capital lease.

A typical term of our rental equipment leases is 5 years. The revenue stream is based on monthly usage and recognized in the month of usage. We record purchased rental equipment, including all installation and freight charges, as a fixed asset. We are typically responsible for all repairs and maintenance expenses on rental equipment.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets: Goodwill is the excess of cost over the fair value of the net assets of businesses acquired. Goodwill and certain intangible assets are no longer amortized but are assessed at least annually for impairment with any such impairment recognized in the period identified. We perform our goodwill impairment test at least annually at December 31, unless there is a triggering event, in which case a test would be performed at the time that such triggering event occurs. We test for goodwill impairment using a two-step process and at the level of the recycling reporting units to which all the goodwill is related in accordance with ASC Topic 350 - Intangibles-Goodwill and Other. In the first step, we determine whether to impair goodwill by comparing the fair value of the recycling reporting unit as a whole (the present value of expected cash flows) to its carrying value including goodwill or by obtaining a valuation from an outside source. A reporting unit is an operating segment or one level below an operating segment (referred to as a "component"). A component is considered a reporting unit for purposes of goodwill testing if the component constitutes a business for which discrete financial information is available and segment management regularly reviews the operating results of that component. We have identified two reporting units, and we obtained a valuation from an outside source. If necessary, the second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination.

Intangibles

Intangibles: Purchased intangible assets are initially recorded at cost and finite life intangible assets are amortized over their useful economic lives on a straight line basis. Intangible assets having indefinite lives and intangible assets that are not yet ready for use are not amortized and are reviewed annually for impairment as required by the FASB's ASC.

Intangible assets are considered to have indefinite lives when, based on an analysis of all of the relevant factors, there is no foreseeable limit to the period over which the asset is expected to generate cash flows for the Company. The factors considered in making this determination include the existence of contractual rights for unlimited terms and the life cycles of the products and processes that depend on the asset.

Advertising Expense

Advertising Expense: Advertising costs are charged to expense in the period the costs are incurred.

Derivative and Hedging Activities

Derivative and Hedging Activities: We are exposed to market risk stemming from changes in metal commodity prices, specifically nickel, and interest rates. In the normal course of business, we actively manage our exposure to these market risks by entering into various hedging transactions, authorized under established policies that place clear controls on these activities. These transactions utilize exchange traded derivatives or over-the-counter derivatives with investment grade counter-parties. Derivative financial instruments currently used by us consist of commodity futures, options and swap contracts. Derivative financial instruments are accounted for under the provisions of the FASB's authoritative guidance titled “ASC 815 - Derivative and Hedging.” Under these standards, derivatives are carried on the balance sheet at fair value. If the derivative is designated as a fair value hedge, such as our commodity hedges, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, such as our interest rate swaps, the effective portions of changes in the fair value of the derivatives are recorded as a component of other comprehensive income or loss and are recognized in the statement of operations when the hedged item affects earnings. If the derivative is not designated as a hedge, changes in the fair value are recognized in other income or expense. Ineffective portions of changes in the fair value of cash flow hedges are also recognized in gain or loss on derivative liabilities. Cash flows related to derivatives are included in operating activities.

Beginning in October 2008, we began to utilize derivative instruments in the form of interest rate swaps to assist in managing our interest rate risk. We do not enter into any interest rate swap derivative instruments for trading purposes. We recognize as an adjustment to interest expense the differential paid or received on interest rate swaps. We include in other comprehensive income the change in the fair value of the interest rate swap, which is established as an effective hedge. We include the required disclosures for interest rate swaps in Note 3 – “Notes Payable to Bank” of our Notes to Consolidated Financial Statements.

Beginning in July 2012, we began to utilize 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. We include the gain or loss on the hedged items and the offsetting loss or gain on the related commodity hedge in cost of goods sold. We assess the effectiveness of a commodity hedge contract based on changes in the contract's fair value. The changes in the market value of such contracts have historically been, and are expected to continue to be, highly effective at offsetting changes in the price of the hedged items. The amounts representing the ineffectiveness of these hedges are not expected to be significant.

Income Taxes

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. We use 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 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 uncertain tax positions recognized as of December 31, 2012 and 2011.

As a policy, the Company recognizes interest accrued related to unrecognized tax positions in interest expense and penalties in operating expenses.

Earnings Per Share

Earnings Per Share: Basic earnings per share are computed by dividing net income by the weighted average number of common shares outstanding during the year. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding plus the dilutive effect of stock options.

Stock Option Plans

Stock Option Plans: We have an employee stock option plan under which we may grant options for up to 2.4 million shares of common stock, which are reserved by the board of directors for issuance of stock options. We provide compensation benefits by granting stock options to employees and directors. The exercise price of each option is equal to the market price of our stock on the date of grant. The maximum term of the option is five years. We account for this plan based on FASB’s authoritative guidance titled "ASC 718 - Compensation - Stock Compensation." We recognize share-based compensation expense for the fair value of the awards, as estimated using the Modified Black-Scholes-Merton Model, on the date granted on a straight-line basis over their vesting term. Compensation expense is recognized only for share-based payments expected to vest. We estimate forfeitures at the date of grant based on our historical experience and future expectations.

There are two significant inputs into the Modified Black-Scholes-Merton option-pricing model: expected volatility and expected term. We estimate expected volatility based on traded option volatility of our 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 our long-term incentive plan and represents the period of time that stock option awards granted are expected to be outstanding. 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 we use different assumptions, stock-based compensation expense could be materially different in the future. In addition, we are required to estimate the expected forfeiture rate, and only recognize expense for those shares expected to vest. If our actual forfeiture rate is materially different from its estimate, the stock-based compensation expense could be significantly different from what we have recorded in the current period.

Impact of Recently Issued Accounting Standards

Impact of Recently Issued Accounting Standards: In September 2011, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2011-08, an amendment to Topic 350, Intangibles—Goodwill and Other, which simplifies how entities test goodwill for impairment. Previous guidance under Topic 350 required an entity to test goodwill for impairment using a two-step process on at least an annual basis. First, the fair value of a reporting unit was calculated and compared to its carrying amount, including goodwill. Second, if the fair value of a reporting unit was less than its carrying amount, the amount of impairment loss, if any, was required to be measured. Under the amendments in this update, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads the entity to determine that it is more likely than not that its fair value is less than its carrying amount. If after assessing the totality of events or circumstances, an entity determines that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then the two-step impairment test is unnecessary. If the entity concludes otherwise, then it is required to test goodwill for impairment under the two-step process as described under paragraphs 350-20-35-4 and 350-20-35-9 under Topic 350. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, the quarter ending March 31, 2012 for us, and early adoption was permitted. The adoption of ASU 2011-08 did not have a material impact on our Condensed Consolidated Financial Statements.

In June 2011, the FASB issued ASU 2011-05, which is an update to Topic 220, “Comprehensive Income.” This update eliminates the option of presenting the components of other comprehensive income as part of the statement of changes in stockholders’ equity, requires consecutive presentation of the statement of net income and other comprehensive income and requires reclassification adjustments from other comprehensive income to net income to be shown on the financial statements. ASU 2011-05 is effective for all interim and annual reporting periods beginning after December 15, 2011, the quarter ending March 31, 2012 for us. However, in December 2011, the FASB issued ASU 2011-12, which has deferred the specific requirement within ASU 2011-05 to present on the face of the financial statements items that are reclassified from accumulated other comprehensive income to net income separately with their respective components of net income and other comprehensive income. Entities should continue to report reclassifications out of accumulated comprehensive income consistent with the presentation requirements in effect before ASU 2011-05. As ASU No. 2011-05 relates only to the presentation of Comprehensive Income, the adoption of such did not have a material impact on our Condensed Consolidated Financial Statements.

In May 2011, the FASB issued ASU 2011-04, which is an update to Topic 820, “Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (“IFRS”)." The amendments in this ASU generally represent clarification of Topic 820, but also include instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed. This update results in common principles and requirements for measuring fair value and for disclosing information about fair value measurements in accordance with GAAP and IFRS. The amendments are effective for interim and annual periods beginning after December 15, 2011, the quarter ending March 31, 2012 for us, and are to be applied prospectively. Early application was not permitted. The adoption of ASU 2011-04 did not have a material impact on our Condensed Consolidated Financial Statements.
