	2. Concentrations:

	Major Customers and Products

	In fiscal 2013, 2012 and 2011, the Company derived 64%, 63%, and 61%, respectively, of total sales from five customers, although not all the same customers in each year. Accounts receivable and unbilled receivables related to those top five customers was $5.9 million, $2.4 million, and $1.8 million as at September 30, 2013, 2012 and 2011, respectively.

	During fiscal 2013, two of the Company’s customers, Eclipse Aerospace Inc. (“Eclipse”) and American Airlines Inc. (“AAI”) accounted for 24% and 14% of total sales, respectively. In fiscal 2012, three of the Company’s customers, Eclipse, FedEx Corporation (“FedEx”), and National Nuclear Security Administration accounted for 20%, 14%, and 13% of total sales, respectively. In fiscal 2011, two of the Company’s customers, Eclipse and FedEx, accounted for 20% and 15% of total sales, respectively.

	Flat Panel sales were 88%, 87%, and 79% of total sales in the years ended September 30, 2013, 2012 and 2011, respectively. Sales of air data systems and components were 12%, 13%, and 21% of total sales for the years ended September 30, 2013, 2012 and 2011, respectively. Sales to government contractors and agencies accounted for approximately 28%, 45% and 30% of total sales during fiscal years 2013, 2012 and 2011, respectively. While under these contracts, the government agency or general contractor typically retains the right to terminate the contract at any time at its convenience. To date these contracts have generally included provisions requiring the payment to the Company of all revenue earned and costs incurred by the Company through the date of contract termination and do not entitle the customer to receive a refund of any previously paid fees.

	On November 29, 2011, AMR Corporation, the parent company of AAI and certain of its other U.S.-based subsidiaries filed voluntary petitions for Chapter 11 reorganization in the U.S. Bankruptcy Court for the Southern District of New York (the “Bankruptcy”). The Company’s revenues from AAI accounted for 14%, 5% and 8% of total revenue for the fiscal years 2013, 2012 and 2011, respectively. (See also Note 14 - Commitments and Contingencies).

	Major Suppliers

	The Company buys several of its components from sole source suppliers. Although there are a limited number of suppliers of particular components, management believes other suppliers could provide similar components on comparable terms.

	During fiscal 2013 and 2012 the Company had one supplier that accounted for 30% and 20%, respectively, of the Company’s total inventory purchases.

	Concentration of Credit Risk

	Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash balances and accounts receivable. The Company invests its excess cash where preservation of principal is the major consideration. The Company’s customer base consists principally of companies within the aviation industry. The Company may request advance payments and/or letters of credit from new customers or existing customers whose credit ratings do not meet the Company’s standards for extending normal credit terms.

	The Company maintained reserves for doubtful accounts of $0 million and $0.2 million at September 30, 2013 and 2012, respectively. The reserve balance for fiscal 2012 is related to sales of Engineering Development Contract services (“EDC”) to a customer that was impacted negatively by the current economic environment. As of September 30, 2013, the Company had pre-Bankruptcy outstanding accounts receivable of $760,000 from AAI. The Bankruptcy Court recently approved the settlement of the U.S. Department of Justice’s antitrust lawsuit challenging the AMR - U.S. Airways merger, and the merger was consummated on December 9, 2013. Shortly thereafter, the Company collected in full, the outstanding amount of $760,000. (See also Note 14 - Commitments and Contingencies).

	3. Summary of Significant Accounting Policies:

	Principles of Consolidation

	The consolidated financial statements include the accounts of the Company and its subsidiaries. All inter-company balances and transactions have been eliminated in consolidation.

	Use of Estimates

	The financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America, which require management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from those estimates. Estimates are used in accounting for, among other items, long term contracts, allowances for doubtful accounts, inventory obsolescence, product warranty cost liabilities, income taxes, engineering and material costs on EDC programs, percentage of completion on EDC contracts, recoverability of long-lived assets and contingencies. Estimates and assumptions are reviewed periodically and the effects of changes, if any, are reflected in the Consolidated Statement of Operations in the period they are determined.

	Cash and Cash Equivalents

	Highly liquid investments purchased with an original maturity of three months or less are classified as cash equivalents. Cash equivalents at September 30, 2013 and 2012 consist of cash on deposit and cash invested in money market funds with financial institutions.

	Inventory valuation

	Inventories are stated at the lower of cost (first-in, first-out) or market and consist of the following:

			September 30,			September 30,
			2013			2012
	Raw materials		$	3,126,592		$	2,752,833
	Work-in-process		857,602			555,495
	Finished goods		393,319			493,219
			$	4,377,513		$	3,801,547

	Property and Equipment

	Property and equipment are stated at cost. Depreciation is provided using an accelerated method over estimated useful lives of the assets (the lesser of three to seven years or over the lease term), except for the corporate airplane and manufacturing facility, which are depreciated using the straight-line method over estimated useful lives of ten years and thirty-nine years. During fiscal 2013, no depreciation was provided for the airplane because it had been depreciated to its estimated salvage value. Major additions and improvements are capitalized, while maintenance and repairs that do not improve or extend the life of assets are charged to expense as incurred.

	Long-Lived Assets

	The Company assesses the impairment of long-lived assets in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 360-10, “Property, Plant and Equipment”. This statement requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In addition, long-lived assets to be disposed of should be reported at the lower of the carrying amount or fair value less cost to sell. The Company considers historical performance and future estimated results in its evaluation of potential impairment and then compares the carrying amount of the asset to estimated future cash flows expected to result from use of the asset. If the carrying amount of the asset exceeds the estimated expected undiscounted future cash flows, the Company measures the amount of the impairment by comparing the carrying amount of the asset to its fair value. The estimation of fair value is generally measured by discounting expected future cash flows. No impairment charges were recorded in fiscal years 2013, 2012 or 2011.

	Revenue Recognition

	The Company enters into sales arrangements with customers that, in general, provide for the Company to design, develop, manufacture, and deliver large flat-panel display systems, flight information computers, and advanced monitoring systems that measure and display critical flight information, including data relative to aircraft separation, airspeed, altitude, and engine and fuel data measurements. The Company’s sales arrangements may include multiple deliverables as defined in FASB ASC Topic 605-25 “Multiple-Element Arrangements” (“ASC Topic 605-25”), which typically include design and engineering services, and the production and delivery of the flat panel display and related components. The Company includes any design and engineering development services elements in EDC sales and any functional upgrade and product elements in product sales in the accompanying consolidated statement of operations.

	To the extent that an arrangement contains software elements that are essential to the functionality of tangible products sold in the arrangement, the Company recognizes revenue for the deliverables in accordance with the guidance included in FASB Accounting Standards Update (“ASU”) 2009-14, “Revenue Arrangements That Include Software Elements” (“ASU 2009-14”), FASB ASU 2009-13, “Multiple-Deliverable Revenue Arrangements—a consensus of the FASB Emerging Issues Task Force” (“ASU 2009-13”), and FASB ASC Topic 605, “Revenue Recognition” (“ASC Topic 605”).

	To the extent that an arrangement contains software components, which include functional upgrades, that the Company sells on a standalone basis and which it has deemed outside the scope of the exception defined by ASU 2009-14, the Company recognizes software revenue in accordance with FASB ASC Topic 985, “Software” (“ASC Topic 985”).

	Multiple Element Arrangements

	The Company identifies all goods and/or services that are to be delivered separately under such a sales arrangement and allocates sales to each deliverable (if more than one) based on that deliverable’s selling price. The Company then considers the appropriate recognition method for each deliverable. The Company’s multiple element arrangements can include defined design and development activities and/or functional upgrades, along with product sales.

	The Company utilizes the selling price hierarchy that has been established by ASU 2009-13, which requires that the selling price for each deliverable be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. To the extent that an arrangement includes a deliverable for which estimated selling price is used, the Company determines the best estimate of selling price by applying the same pricing policies and methodologies that it would use to determine the price to sell the deliverable on a standalone basis.

	To the extent that an arrangement contains defined design and EDC activities as identified deliverables in addition to products (resulting in a multiple element arrangement), the Company recognizes as EDC sales amounts earned during the design and development phase of the contract following the guidance included in FASB ASC Topic 605-35, “Construction-Type and Production-Type Contracts” (“ASC Topic 605-35”). To the extent that multiple element arrangements include product sales, sales are generally recognized once revenue recognition criteria for the product deliverables have been met based on the provisions of ASC Topic 605.

	Single Element Arrangements

	Products

	To the extent that a single element arrangement provides for product sales and repairs, the Company recognizes sales when revenue recognition criteria for the product deliverables have been met based on the provisions of ASC Topic 605. In addition, the Company also receives orders for equipment and parts. Generally, revenues from the sale of such products are recognized upon shipment to customers.

	The Company may offer its customers extended warranties for additional fees. These warranty sales are recorded as deferred revenue and recognized as sales on a straight-line basis over the warranty period.

	Engineering Development Contracts

	The Company may enter into contracts to perform specified design and EDC services related to its products. The Company recognizes revenue from these arrangements as EDC sales, following the guidance included in ASC Topic 605-35, and considers the nature of these contracts (including term, size of contract, and level of effort) when determining the appropriate accounting treatment for a particular contract. Certain of these contracts are accounted for under the percentage-of-completion method of accounting when the Company determines that progress toward completion is reasonably and reliably estimable, and the contract is long-term in nature. The Company uses the completed contract method for all other contracts. Sales and profit margins under the percentage-of-completion method are recorded based on the ratio of actual costs incurred to total estimated costs expected to be incurred related to the contract under the cost-to-cost method (for development effort).

	The percentage-of-completion method of accounting requires the Company to estimate the profit margin for each individual contract or contract segment and to apply that profit margin on a uniform basis as sales are recorded under the contract. The estimation of profit margin requires the Company to make projections of the total sales to be generated and the total costs that will be incurred under a contract. These projections require the Company to make numerous assumptions and estimates relating to items such as the complexity of design and related development costs, performance of subcontractors, availability and cost of materials, engineering productivity, prototype costs, overhead cost and capital costs. These contracts sometimes include purchase options for additional quantities and for customer change orders for additional or revised product functionality. Revenues and costs related to profitable purchase options are included in the Company’s estimates only when the options are exercised, while revenues and costs related to unprofitable purchase options are included in the Company’s estimates when exercise is determined to be probable. Revenues related to change orders are included in profit estimates only if they can be reliably estimated and collectability is reasonably assured. Purchase options and change orders are accounted for either as an integral part of the original contract, or separately depending upon the nature and value of the item, in the period in which any change order or purchase option becomes effective. Anticipated losses on contracts are recognized in full in the period in which losses become probable and estimable.

For contracts for which uncertainty regarding the performance against certain contract terms remains, and in which no loss is expected, the Company uses the zero profit margin approach to applying the percentage-of-completion method following the guidance included in ASC Topic 605-35.

Estimates of profit margins for contracts are reviewed by the Company on a quarterly basis. Assuming the initial estimates of revenues and costs under a contract are accurate, the percentage-of-completion method results in the profit margin being recorded evenly as revenue is recognized under the contract. Changes in these underlying estimates due to revisions in revenue and cost estimates or the exercise of contract options may result in profit margins being recognized unevenly over a contract as such changes are accounted for on a cumulative basis in the period in which the estimates are revised. Significant changes in estimates related to accounting for long-
term contracts may have a material effect on the Company’s results of operations in the period in which the revised estimates are made. Cumulative catch-up adjustments if any, resulting from changes in estimates, are included in results of operations and disclosed in the notes to consolidated financial statements.

Income Taxes

Income taxes are recorded in accordance with FASB ASC Topic 740, “Income Taxes” (“ASC Topic 740”), which utilizes a balance sheet approach to provide for income taxes. Under this method, the Company recognizes deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of the Company’s assets, liabilities and expected benefits of utilizing net operating loss (NOL”)and tax credit carry-forwards. The impact on deferred taxes of changes in tax rates and laws, if any, are applied to the years during which temporary differences are expected to be settled and are reflected in the consolidated financial statements in the period of enactment.

Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more likely than not that some portion of the deferred tax asset will not be realized. Significant weight is given to evidence that can be verified objectively, and significant management judgment is required in determining any valuation allowances recorded against net deferred tax assets. The Company evaluates deferred income taxes on a quarterly basis to determine if valuation allowances are required by considering available evidence. Deferred tax assets are recognized when expected future taxable income is sufficient to allow the related tax benefits to reduce taxes that would otherwise be payable. The sources of taxable income that may be available to realize the benefit of deferred tax assets are future reversals of existing taxable temporary differences, future taxable income exclusive of reversing temporary differences and credit carry-forwards, taxable income in carry-back years, and tax planning strategies which are both prudent and feasible. The Company believes that its estimate of future taxable income is inherently uncertain, and if its current or future operations generate losses, further adjustments to the valuation allowance would be possible. The current balance of the deferred tax valuation allowance relates principally to NOL of certain state taxing jurisdictions. There is currently no assurance of such future income before income taxes.

The accounting for uncertainty in income taxes requires a more likely than not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. The Company records a liability for the difference between the (i) benefit recognized and measured for financial statement purposes and (ii) the tax position taken or expected to be taken on the Company’s tax return. To the extent that the Company’s assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. The Company has elected to record any interest or penalties associated with uncertain tax positions as income tax expense.

The Company files a consolidated United States federal income tax return. The Company prepares and files tax returns based on the interpretation of tax laws and regulations, and records estimates based on these judgments and interpretations. In the normal course of business, the tax returns are subject to examination by various taxing authorities. Such examinations may result in future tax and interest assessments by these taxing authorities, and the Company records a liability when it is probable that there will be an assessment. The Company adjusts the estimates periodically as a result of ongoing examinations by and settlements with the various taxing authorities, and changes in tax laws, regulations and precedent. The consolidated tax provision of any given year includes adjustments to prior years’ income tax accruals that are considered appropriate, and any related estimated interest. Management believes that adequate accruals have been made for income taxes. Differences between estimated and actual amounts determined upon ultimate resolution, individually or in the aggregate, are not expected to have a material effect on the Company’s consolidated financial position, but could possibly be material to its consolidated results of operations or cash flow of any one period.

Engineering Development

Total engineering development expense is comprised of both internally funded research and development (“R&D”) and product development and design charges related to specific customer EDC. Engineering development expense consists primarily of payroll-related expenses of employees engaged in EDC, engineering related product materials and equipment and subcontracting costs. R&D charges incurred for product design, product enhancements and future product development are expensed as incurred. Product development and design charges related to specific customer EDC are charged to cost of sales-EDC.

Comprehensive Income

Pursuant to FASB ASC Topic 220, “Comprehensive Income” (“ASC Topic 220”), the Company is required to classify items of other comprehensive income by their nature in a financial statement and display the accumulated balance of other comprehensive income separately from retained earnings and additional paid-in capital in the equity section of its condensed consolidated balance sheets. For fiscal 2013, 2012 and 2011 comprehensive income consisted of net income only, and there were no items of other comprehensive income for any of the periods presented.

Fair Value of Financial Instruments

The net carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and short-term debt approximate their fair value because of the short-term nature of these instruments. For financial assets and liabilities measured at fair value on a recurring basis, fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value as follows:

Level 1 — Unadjusted quoted prices that are available in active markets for the identical assets or liabilities at the measurement date.

Level 2 — Other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly, including:

· Quoted prices for similar assets or liabilities in active markets;
· Quoted prices for identical or similar assets in non-active markets;
· Inputs other than quoted prices that are observable for the asset or liability; and
· Inputs that are derived principally from or corroborated by other observable market data.

Level 3 — Unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.

The following table sets forth by level within the fair value hierarchy the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2013 and 2012, according to the valuation techniques the Company used to determine their fair values.

Share-Based Compensation

The Company accounts for share-based compensation under FASB ASC Topic 505-50, “Equity-Based Payments to Non-Employees” (“ASC Topic 505-50”) and ASC Topic 718, “Stock Compensation” (“ASC Topic 718”), which requires the Company to measure the cost of employee or non-employee director services received in exchange for an award of equity instruments based on the grant-date fair value of the award using an option pricing model. That cost is recognized over the period during which an employee or non-employee director is required to provide service in exchange for the award.

Warranty

The Company offers warranties on some products of various lengths. At the time of shipment, and when sold separately, the Company establishes a reserve for estimated costs of warranties based on its best estimate of the amounts necessary to settle future and existing claims using historical data on products sold as of the balance sheet date. The length of the warranty period, the product’s failure rates, and the customer’s usage affect warranty cost. If actual warranty costs differ from the Company’s estimated amounts, future results of operations could be affected adversely. Warranty cost is recorded as cost of sales, and the reserve balance recorded as an accrued expense. While the Company maintains product quality programs and processes, its warranty obligation is affected by product failure rates and the related corrective costs. If actual product failure rates and/or corrective costs differ from the estimates, the Company revises estimated warranty liability accordingly.

New Accounting Pronouncements

In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (“ASU 2013-11”). ASU 2013-11 provides that a liability related to an unrecognized tax benefit should be offset against a deferred tax asset for a NOL carryforward, a similar tax loss or a tax credit carryforward if such liability is to be settled by reducing an available tax carryforward in the event the uncertain tax position is disallowed. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 for public entities, with early adoption permitted. The adoption of ASU 2013-11 during the fourth quarter of fiscal year ending September 20, 2013 did not have a material impact on the Company’s consolidated financial statements.

In May 2011, the FASB issued ASU 2011-04, “Fair Value Measurement (Topic 820), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (“ASU 2011-04”). ASU 2011-04 amends the fair value measurement and disclosure guidance to converge accounting principles generally accepted in the United States of America (“GAAP”) and International Financial Reporting Standards (“IFRS”) requirements for measuring amounts at fair value as well as disclosures about these measurements. ASU 2011-04 was to be adopted prospectively and was effective for the interim and annual periods beginning after December 15, 2011. The adoption of ASU 2011-04 did not have a material impact on the Company’s consolidated financial statements.

In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (“ASU 2011-05”) which requires that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement would present total net income and its components followed consecutively by a second statement that would present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. ASU 2011-05 is to be adopted retrospectively and is effective for annual periods beginning after December 2011. The adoption of ASU 2011-05 did not have an impact on the Company’s consolidated financial position, results of operations, or cash flows, because the guidance changes only the presentation of financial information. In February 2013, the FASB issued ASU 2013-02 requiring the effective date for implementation of the deferred elements of ASU 2011-05 to be effective for reporting periods beginning after December 15, 2012, with early adoption permitted.

	Net income per share is calculated pursuant to ASC Topic 260, Earnings per Share (“ASC Topic 260”). Basic earnings per share (“EPS”) excludes potentially dilutive securities and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS is computed assuming the conversion or exercise of all dilutive securities such as employee stock options.

	The number of incremental shares from the assumed exercise of stock options is calculated by using the treasury stock method. As of September 30, 2013 and 2012, there were 824,834 and 836,200 options to purchase common stock outstanding, respectively. The average outstanding diluted shares calculation excludes options with an exercise price that exceeds the average market price of shares during the period. For fiscal years 2013, 2012 and 2011, 445,472, 806,200, and 184,300 options to purchase common stock, respectively, were excluded from the computation of diluted earnings per share, because the effect would be anti-dilutive.

	5. Unbilled Receivables:

	Unbilled receivables principally represent sales recorded under the percentage-of-completion method of accounting that have not been billed to customers in accordance with applicable contract terms. Unbilled receivables, net of progress payments, were $6.5 million and $1.6 million at September 30, 2013 and 2012, respectively.

	The percentage-of-completion method of accounting for EDC revenue, requires estimates of profit margins for contracts be reviewed by the Company on a quarterly basis. Assuming the initial estimates of revenues and costs under a contract are accurate, the percentage-of-completion method results in the profit margin being recorded evenly as revenue is recognized under the contract. Changes in these underlying estimates due to revisions in revenue and cost estimates or the exercise of contract options may result in profit margins being recognized unevenly over a contract because such changes are accounted for on a cumulative basis in the period in which the estimates are revised. Significant changes in estimates related to accounting for long-term contracts may have a material effect on the Company’s results of operations in the period in which the revised estimates are made. Cumulative catch-up adjustments resulting from changes in estimates reduced operating income by $444,000, $8,000 and $0 during fiscal years ended September 30, 2013, 2012 and 2011, respectively.

	Effective income tax rate		6	%	(411.9	)%	20.4	%

	On January 1, 2013, Congress enacted the American Taxpayer Relief Act of 2012 which retroactively reinstated and extended the Research and Development Tax Credit (“R&D Tax Credit”) from January 1, 2012 to December 31, 2013. The current year effective income tax rate reflects the benefit of the retroactive application of the R&D Tax Credit for nine months from the fiscal year ended September 30, 2012, plus a full year benefit for the fiscal year ended September 30, 2013 as required by ASC Topic 740.

	In December of 2010, Congress enacted a two-year extension of the R&D Tax Credit, which retroactively reinstated and extended the R&D Tax Credit for amounts paid or incurred from January 1, 2010 to December 31, 2011. The Company recognized the entire impact of this retroactive extension in the quarter ended December 31, 2010, as required by ASC Topic 740. The Company’s effective tax rate for the year ended September 30, 2011 reflects the benefit of the R&D Tax Credit generated over the period January 1, 2010 through September 30, 2011. The amount reported above for the year ended September 30, 2012 reflects R&D Tax Credits generated from October 1, 2011 through December 31, 2011.

	The deferred tax effect of temporary differences giving rise to the Company’s deferred tax assets and liabilities consists of the components below:

Net deferred tax asset		$	2,002,679		$	518,796		$	1,588,162		$	717,889

At September 30, 2013, the Company had state NOL carryforwards of $21.4 million, which begin to expire in varying amounts after the fiscal year ending September 30, 2026. In addition, the Company has federal R&D Tax Credit carryforwards of approximately $690,000, which begin to expire in varying amounts after fiscal year ending September 30, 2029, and state R&D Tax Credit carryforwards of $208,000 (net of federal impact), which begin to expire in varying amounts after the fiscal year ending September 30, 2023.

Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more likely than not that some portion of the deferred tax asset will not be realized. Significant weight is given to evidence that can be verified objectively, and significant management judgment is required in determining any valuation allowances recorded against net deferred tax assets. The Company evaluates deferred income taxes on a quarterly basis to determine if valuation allowances are required by considering available evidence, including historical and projected taxable income and tax planning strategies which are both prudent and feasible. ASC Topic 740 requires the consideration of a valuation allowance to reflect the likelihood of realization of deferred tax assets. Significant management judgment is required in determining any valuation allowance recorded against net deferred tax assets.

At September 30, 2013, the balance of the deferred tax valuation allowance relates principally to NOL of certain state taxing jurisdictions. The valuation allowance decreased by $16,000 for the year ended September 30, 2013, primarily due to the partial reversal of state valuation allowances related to state NOL and other deferred tax assets, based on forecasts of future taxable income. In the event the Company were to determine that it would be able to realize additional state deferred tax assets in the future, an adjustment would be made to the valuation allowance which would reduce the provision for income taxes. The Company will continue to maintain the balance of the valuation allowance until an appropriate level of profitability is sustained to warrant a conclusion that it is no longer more likely than not that a portion of these net deferred tax assets will not be realized in future periods. There is currently no assurance of such future income before taxes. The Company believes that its estimate of future taxable income is inherently uncertain, and if its current or future operations generate losses, further adjustments to the valuation allowance are possible.

At September 30, 2012, the Company considered all available evidence, including the recent history of income before income taxes, together with projections of profitability in future periods. As a result of this analysis, the Company determined that the positive evidence, which related primarily to the recent history of income before income taxes, and projections of future profits, was sufficient to conclude that it was appropriate to reverse $2.4 million of valuation allowances previously recorded against its net federal deferred tax assets.

Following is a reconciliation of beginning and ending balances of total amounts of gross unrecognized tax benefits:

		For the Fiscal Year Ended September 30,
		2013			2012			2011
Balance at beginning of year		$	403,000		$	491,000		$	425,000
Unrecognized tax benefits related to prior years		—			—			—
Unrecognized tax benefits related to current year		120,000			12,000			67,000
Settlements		—			—			—
Decrease in unrecognized tax benefits due to the lapse of applicable statute of limitations		(31,000		)	(100,000		)	(1,000		)

Balance at end of year		$	492,000		$	403,000		$	491,000

The total liabilities associated with the unrecognized tax benefits that, if recognized, would impact the Company’s effective tax rate were $492,000, $403,000 and $491,000 at September 30, 2013, 2012 and 2011, respectively. It is not anticipated that the balance of unrecognized tax benefits at September 30, 2013 will change significantly over the next twelve months. The balance of unrecognized tax benefits as reflected in the table above at September 30, 2013 and 2012, are recorded on the balance sheet as a reduction to deferred tax assets, except for approximately $10,000 and $92,000 which are included in Other Liabilities at September 30, 2013 and 2012, respectively.

The Company’s policy is to recognize interest accrued and, if applicable, penalties related to unrecognized tax benefits in income tax expense for all periods presented. The Company has accrued approximately $1,000 and $4,000 for the payment of interest, net of tax benefits, at September 30, 2013 and 2012, respectively. There is no accrual recorded for penalties.

For the fiscal year ended September 30, 2013, 2012 and 2011, the Company recognized expense (benefit) of $(3,000), $(8,000) and $4,000, respectively, for interest (net of federal impact) within income tax expense.

The Company is subject to income taxes in the U.S. federal and various state jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of related tax laws and regulations and require significant judgment to apply. The Company’s federal income tax returns for the fiscal years ended September 30, 2011 and thereafter are open years subject to examination by the Internal Revenue Service (“IRS”). The Company files income tax returns in various state jurisdictions, as appropriate, with varying statutes of limitation.

	13. Share-Based Compensation:

	The Company accounts for share-based compensation under the provisions of ASC Topic 505-50 and ASC Topic 718 by using the fair value method for expensing stock options and stock awards.

	Total share-based compensation expense was $912,000, $645,000 and $371,000 for the fiscal years ended September 30, 2013, 2012 and 2011, respectively. The income tax impact recognized as a (charge) credit to additional paid in capital in the statement of shareholders’ equity related to share-based compensation arrangements was ($33,000), ($5,000) and $7,000 for the fiscal years ended September 30, 2013, 2012 and 2011, respectively. Compensation expense related to share-based awards is recorded as a component of selling general and administrative expenses.

	By unanimous consent of the Company’s Board of Directors on January 25, 2013, the applicable option exercise price of each outstanding option to purchase common stock was reduced by $1.50 per share pursuant to the terms of the 1998 Plan or the 2009 Plan (each as defined below), as applicable, to offset the dilutive impact of the special cash dividend paid by the Company on December 27, 2012 to common shareholders of record on December 17, 2012. As required by ASC Topic 718, the Company recorded an expense of $22,000 related to the vested outstanding options as a result of this one-time reduction to the option exercise price in the quarter ended March 31, 2013. For non-vested options, the Company added the additional compensation cost of $59,000 to the remaining unrecognized compensation cost for the original share options, granted under the 2009 Plan, and will expense the total amount ratably over the remaining vesting period of the options in accordance with the guidance provided by ASC Topic 718.

	The Company has three share-based compensation plans, the 1998 Stock Option Plan (the “1998 Plan”), the 2003 Restricted Stock Plan (the “Restricted Plan”) and the 2009 Stock-Based Incentive Compensation Plan (the “2009 Plan”). These plans were approved by the Company’s shareholders. The 1998 Plan expired on November 13, 2008. The last awards under the Restricted Plan were made in 2010 and no further shares remain to be awarded under the Restricted Plan.

	1998 Stock Option Plan

	The 1998 Plan allowed granting of incentive and nonqualified stock options to employees, officers, directors and independent contractors and consultants. No stock options were granted to independent contractors or consultants under this plan. Incentive stock options granted under the 1998 Plan have exercise prices that are at least equal to the fair value of the common stock on grant date. Nonqualified stock options granted under the plan have exercise prices that are less than, equal to or greater than the fair value of the common stock on the date of grant. The Company reserved 3,389,000 shares of common stock for awards under the plan. On November 13, 2008, the 1998 Plan expired and no additional shares were granted under the 1998 Plan after that date.

	Following is a summary of option activity under the 1998 Plan for fiscal years ended September 30, 2013, 2012, and 2011 and changes during the periods then ended:

	In fiscal 2013 and 2012, no options were granted under the 1998 Plan; therefore, there is no weighted-average grant date fair value and no intrinsic value attributable to individual options granted. 226,800 and 0 options under the 1998 Plan were exercised in fiscal 2013 and 2012, respectively.

	The following table summarizes information about stock options under the 1998 Plan at September 30, 2013:

	Fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. Options are exercisable over a maximum term of ten years from date of grant and typically vest over periods of three to five years from the grant date. The expected term of options represents the period of time that options granted are expected to be outstanding and is based on historical experience. Expected volatility is based on historical volatility of the Company’s stock price. The risk free interest rate is based on U.S. Treasuries with maturities consistent with the expected life of the options in effect at the time of grant. Compensation expense for employee stock options includes an estimate for forfeitures, and is recognized ratably over the vesting term. Because no options were granted from the 1998 Plan in fiscal 2013, 2012 and 2011, the data for expected dividend, expected volatility, weighted average risk-free interest rate and expected lives is not applicable.

	Total compensation expense associated with stock option awards to employees under the 1998 Plan was $34,000, $67,000 and $117,000 for fiscal years ended September 30, 2013, 2012 and 2011, respectively.

	At September 30, 2013, there is no unrecognized compensation expense related to non-vested stock options under the 1998 Plan that is expected to be recognized during fiscal 2014.

	Restricted Plan

The Restricted Plan for non-employee directors was approved by shareholders at the Company’s February 26, 2004 Annual Meeting of Shareholders. It called for an annual award of non-vested stock having a fair market value of $40,000 at close of business on October 1 of each year for all eligible non-employee directors. The stock awards vest and are issued in four quarterly installments during the fiscal year provided the director is still serving on the board on the quarterly issue date. The last awards under the Restricted Plan were made in 2010, and no further shares remain to be awarded under this Plan. However, the Company continued to make an annual grant of non-vested stock under the 2009 Plan. There were no expenses associated with the grant of non-vested stock to non-employee directors under the Restricted Plan for the fiscal years ended September 30, 2013, 2012 and 2011, respectively.

2009 Stock-Based Incentive Compensation Plan

The 2009 Plan authorizes the grant of stock appreciation rights, restricted stock, options and other equity-based awards under the 2009 Plan (collectively referred to as “Awards”). Options granted under the 2009 Plan may be either “incentive stock options” as defined in section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), or nonqualified stock options, as determined by the Compensation Committee of the Company’s Board of Directors (the “Compensation Committee”).

Subject to an adjustment necessary upon a stock dividend, recapitalization, forward split or reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase or share exchange, extraordinary or unusual cash distribution or other similar corporate transaction or event, the maximum number of shares of common stock available for Awards under the 2009 Plan shall be 1,200,000, all of which may be issued pursuant to Awards of incentive stock options. In addition, the Plan provides that no more than 300,000 shares of common stock per year may be awarded to any employee as a performance-based Award under Section 162(m) of the Code. At September 30, 2013 there were 358,785 shares of common stock available for awards under the plan.

If any Award is forfeited, or if any option terminates, expires or lapses without being exercised, the related shares of common stock subject to such Award will again be available for future grant. Any shares tendered by a participant in payment of the exercise price of an option or the tax liability with respect to an Award (including, in any case, shares withheld from any such Award) will not be available for future grant under the 2009 Plan. If there is any change in the Company’s corporate capitalization, the Compensation Committee must proportionately and equitably adjust the number and kind of shares of common stock which may be issued in connection with future Awards, the number and type of shares of common stock covered by Awards then outstanding under the 2009 Plan, the number and type of shares of common stock available under the 2009 Plan, the exercise or grant price of any Award, or if deemed appropriate, make provision for a cash payment with respect to any outstanding Award, provided that no adjustment may be made that would adversely affect the status of any Award that is intended to be a performance-based Award under Section 162(m) of the Code, unless otherwise determined by the Compensation Committee. In addition, the Compensation Committee may make adjustments in the terms and conditions of any Awards, including any performance goals, in recognition of unusual or nonrecurring events affecting the Company or any subsidiary, or in response to changes in applicable laws, regulations or accounting principles, provided that no adjustment may be made that would adversely affect the status of any Award that is intended to be a performance-based Award under Section 162(m) of the Code, unless otherwise determined by the Compensation Committee.

Fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. Options are exercisable over a maximum term of ten years from date of grant and typically vest over periods of three to five years from the grant date. The expected term of options represents the period of time that options granted are expected to be outstanding and is based on historical experience and the expected turnover rate of the employees receiving the options. Expected volatility is based on historical volatility of the Company’s stock. The risk free interest rate is based on U.S. Treasuries with maturities consistent with the expected life of the options in effect at the time of grant. Compensation expense for employee stock options includes an estimate for forfeitures and is recognized ratably over the vesting term.

Below are the fair value assumptions used to record compensation expense, related to the 2009 Plan, for the following periods identified:

		Fiscal Year Ended September 30,
		2013		2012		2011
Expected dividend rate		—		—		—
Expected volatility		64.6	%	71.1	%	63	%
Weighted average risk-free interest rate		1	%	2.1	%	1.9	%
Expected lives (years)		7.6		8.7		10

Total compensation expense associated with stock option awards to employees under the 2009 Plan was $678,000, $377,000 and $54,000 for fiscal years ended September 30, 2013, 2012 and 2011, respectively.

Total share-based compensation expense associated with the annual grant of stock awards to non-employee directors under the 2009 Plan was $200,000, $200,000 and $200,000 for the fiscal years ended September 30, 2013, 2012 and 2011, respectively.

At September 30, 2013, unrecognized compensation expense of approximately $1,118,000, net of forfeitures, related to non-vested stock options under the 2009 Plan, is expected to be recognized over a period of approximately 3 years.

	A “purchase obligation” is defined as an agreement to purchase goods or services that is enforceable and legally binding on the Company and that specifies all significant terms, including fixed or minimum quantities to be purchased, fixed, minimum or variable price provisions, and the approximate timing of the transaction. These amounts are comprised primarily of open purchase order commitments entered in the ordinary course of business with vendors and subcontractors pertaining to fulfillment of the Company’s current order backlog. The purchase obligations on open purchase orders were $3.8 million, $1.9 million and $1.4 million as of September 30, 2013, 2012 and 2011, respectively.

	Product Liability

	The Company has product liability insurance of $50,000,000. The Company has not experienced any material product liability claims in the past.

	Legal Proceedings

	In the ordinary course of business, the Company is at times subject to various legal proceedings and claims. IS&S does not believe any such matters that are currently pending will have a material effect on its results of operations or financial position.

	On November 29, 2011, AMR Corporation, the parent company of AAI and certain of its other U.S. based subsidiaries filed voluntary petitions for Chapter 11 reorganization in the U.S. Bankruptcy Court for the Southern District of New York (the “Bankruptcy”). For the years ended September 30, 2013 and 2012, AAI accounted for approximately 14% and 5%, respectively, of net sales.

In June 2013, following a trial without a jury, the Court found in favor of the plaintiff awarding him damages for breach of contract, violation of the Pennsylvania Wage Payment and Collection Law, prejudgment interest, and plaintiff’s reasonable attorneys’ fees. The Company has appealed the decision. Pending the outcome of the appeal, the Company has recorded an estimated total liability of $657,000 (which includes the plaintiff’s estimated attorney’s fees), which is recorded as a component of selling, general and administrative expenses for the fiscal year ended September 30, 2013.

Use of Estimates	'
	Use of Estimates

	The financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America, which require management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from those estimates. Estimates are used in accounting for, among other items, long term contracts, allowances for doubtful accounts, inventory obsolescence, product warranty cost liabilities, income taxes, engineering and material costs on EDC programs, percentage of completion on EDC contracts, recoverability of long-lived assets and contingencies. Estimates and assumptions are reviewed periodically and the effects of changes, if any, are reflected in the Consolidated Statement of Operations in the period they are determined.

	Cash and Cash Equivalents

	Highly liquid investments purchased with an original maturity of three months or less are classified as cash equivalents. Cash equivalents at September 30, 2013 and 2012 consist of cash on deposit and cash invested in money market funds with financial institutions.

	Property and Equipment

	Property and equipment are stated at cost. Depreciation is provided using an accelerated method over estimated useful lives of the assets (the lesser of three to seven years or over the lease term), except for the corporate airplane and manufacturing facility, which are depreciated using the straight-line method over estimated useful lives of ten years and thirty-nine years. During fiscal 2013, no depreciation was provided for the airplane because it had been depreciated to its estimated salvage value. Major additions and improvements are capitalized, while maintenance and repairs that do not improve or extend the life of assets are charged to expense as incurred.

Long-Lived Assets	'
	Long-Lived Assets

	The Company assesses the impairment of long-lived assets in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 360-10, “Property, Plant and Equipment”. This statement requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In addition, long-lived assets to be disposed of should be reported at the lower of the carrying amount or fair value less cost to sell. The Company considers historical performance and future estimated results in its evaluation of potential impairment and then compares the carrying amount of the asset to estimated future cash flows expected to result from use of the asset. If the carrying amount of the asset exceeds the estimated expected undiscounted future cash flows, the Company measures the amount of the impairment by comparing the carrying amount of the asset to its fair value. The estimation of fair value is generally measured by discounting expected future cash flows. No impairment charges were recorded in fiscal years 2013, 2012 or 2011.

	The Company enters into sales arrangements with customers that, in general, provide for the Company to design, develop, manufacture, and deliver large flat-panel display systems, flight information computers, and advanced monitoring systems that measure and display critical flight information, including data relative to aircraft separation, airspeed, altitude, and engine and fuel data measurements. The Company’s sales arrangements may include multiple deliverables as defined in FASB ASC Topic 605-25 “Multiple-Element Arrangements” (“ASC Topic 605-25”), which typically include design and engineering services, and the production and delivery of the flat panel display and related components. The Company includes any design and engineering development services elements in EDC sales and any functional upgrade and product elements in product sales in the accompanying consolidated statement of operations.

	To the extent that an arrangement contains software elements that are essential to the functionality of tangible products sold in the arrangement, the Company recognizes revenue for the deliverables in accordance with the guidance included in FASB Accounting Standards Update (“ASU”) 2009-14, “Revenue Arrangements That Include Software Elements” (“ASU 2009-14”), FASB ASU 2009-13, “Multiple-Deliverable Revenue Arrangements—a consensus of the FASB Emerging Issues Task Force” (“ASU 2009-13”), and FASB ASC Topic 605, “Revenue Recognition” (“ASC Topic 605”).

	To the extent that an arrangement contains software components, which include functional upgrades, that the Company sells on a standalone basis and which it has deemed outside the scope of the exception defined by ASU 2009-14, the Company recognizes software revenue in accordance with FASB ASC Topic 985, “Software” (“ASC Topic 985”).

	Multiple Element Arrangements

	The Company identifies all goods and/or services that are to be delivered separately under such a sales arrangement and allocates sales to each deliverable (if more than one) based on that deliverable’s selling price. The Company then considers the appropriate recognition method for each deliverable. The Company’s multiple element arrangements can include defined design and development activities and/or functional upgrades, along with product sales.

	The Company utilizes the selling price hierarchy that has been established by ASU 2009-13, which requires that the selling price for each deliverable be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. To the extent that an arrangement includes a deliverable for which estimated selling price is used, the Company determines the best estimate of selling price by applying the same pricing policies and methodologies that it would use to determine the price to sell the deliverable on a standalone basis.

	To the extent that an arrangement contains defined design and EDC activities as identified deliverables in addition to products (resulting in a multiple element arrangement), the Company recognizes as EDC sales amounts earned during the design and development phase of the contract following the guidance included in FASB ASC Topic 605-35, “Construction-Type and Production-Type Contracts” (“ASC Topic 605-35”). To the extent that multiple element arrangements include product sales, sales are generally recognized once revenue recognition criteria for the product deliverables have been met based on the provisions of ASC Topic 605.

	Single Element Arrangements

	Products

	To the extent that a single element arrangement provides for product sales and repairs, the Company recognizes sales when revenue recognition criteria for the product deliverables have been met based on the provisions of ASC Topic 605. In addition, the Company also receives orders for equipment and parts. Generally, revenues from the sale of such products are recognized upon shipment to customers.

	The Company may offer its customers extended warranties for additional fees. These warranty sales are recorded as deferred revenue and recognized as sales on a straight-line basis over the warranty period.

	Engineering Development Contracts

	The Company may enter into contracts to perform specified design and EDC services related to its products. The Company recognizes revenue from these arrangements as EDC sales, following the guidance included in ASC Topic 605-35, and considers the nature of these contracts (including term, size of contract, and level of effort) when determining the appropriate accounting treatment for a particular contract. Certain of these contracts are accounted for under the percentage-of-completion method of accounting when the Company determines that progress toward completion is reasonably and reliably estimable, and the contract is long-term in nature. The Company uses the completed contract method for all other contracts. Sales and profit margins under the percentage-of-completion method are recorded based on the ratio of actual costs incurred to total estimated costs expected to be incurred related to the contract under the cost-to-cost method (for development effort).

	The percentage-of-completion method of accounting requires the Company to estimate the profit margin for each individual contract or contract segment and to apply that profit margin on a uniform basis as sales are recorded under the contract. The estimation of profit margin requires the Company to make projections of the total sales to be generated and the total costs that will be incurred under a contract. These projections require the Company to make numerous assumptions and estimates relating to items such as the complexity of design and related development costs, performance of subcontractors, availability and cost of materials, engineering productivity, prototype costs, overhead cost and capital costs. These contracts sometimes include purchase options for additional quantities and for customer change orders for additional or revised product functionality. Revenues and costs related to profitable purchase options are included in the Company’s estimates only when the options are exercised, while revenues and costs related to unprofitable purchase options are included in the Company’s estimates when exercise is determined to be probable. Revenues related to change orders are included in profit estimates only if they can be reliably estimated and collectability is reasonably assured. Purchase options and change orders are accounted for either as an integral part of the original contract, or separately depending upon the nature and value of the item, in the period in which any change order or purchase option becomes effective. Anticipated losses on contracts are recognized in full in the period in which losses become probable and estimable.

	For contracts for which uncertainty regarding the performance against certain contract terms remains, and in which no loss is expected, the Company uses the zero profit margin approach to applying the percentage-of-completion method following the guidance included in ASC Topic 605-35.

	Estimates of profit margins for contracts are reviewed by the Company on a quarterly basis. Assuming the initial estimates of revenues and costs under a contract are accurate, the percentage-of-completion method results in the profit margin being recorded evenly as revenue is recognized under the contract. Changes in these underlying estimates due to revisions in revenue and cost estimates or the exercise of contract options may result in profit margins being recognized unevenly over a contract as such changes are accounted for on a cumulative basis in the period in which the estimates are revised. Significant changes in estimates related to accounting for long-
	term contracts may have a material effect on the Company’s results of operations in the period in which the revised estimates are made. Cumulative catch-up adjustments if any, resulting from changes in estimates, are included in results of operations and disclosed in the notes to consolidated financial statements.

Income Taxes	'
	Income Taxes

	Income taxes are recorded in accordance with FASB ASC Topic 740, “Income Taxes” (“ASC Topic 740”), which utilizes a balance sheet approach to provide for income taxes. Under this method, the Company recognizes deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of the Company’s assets, liabilities and expected benefits of utilizing net operating loss (NOL”)and tax credit carry-forwards. The impact on deferred taxes of changes in tax rates and laws, if any, are applied to the years during which temporary differences are expected to be settled and are reflected in the consolidated financial statements in the period of enactment.

	Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more likely than not that some portion of the deferred tax asset will not be realized. Significant weight is given to evidence that can be verified objectively, and significant management judgment is required in determining any valuation allowances recorded against net deferred tax assets. The Company evaluates deferred income taxes on a quarterly basis to determine if valuation allowances are required by considering available evidence. Deferred tax assets are recognized when expected future taxable income is sufficient to allow the related tax benefits to reduce taxes that would otherwise be payable. The sources of taxable income that may be available to realize the benefit of deferred tax assets are future reversals of existing taxable temporary differences, future taxable income exclusive of reversing temporary differences and credit carry-forwards, taxable income in carry-back years, and tax planning strategies which are both prudent and feasible. The Company believes that its estimate of future taxable income is inherently uncertain, and if its current or future operations generate losses, further adjustments to the valuation allowance would be possible. The current balance of the deferred tax valuation allowance relates principally to NOL of certain state taxing jurisdictions. There is currently no assurance of such future income before income taxes.

	The accounting for uncertainty in income taxes requires a more likely than not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. The Company records a liability for the difference between the (i) benefit recognized and measured for financial statement purposes and (ii) the tax position taken or expected to be taken on the Company’s tax return. To the extent that the Company’s assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. The Company has elected to record any interest or penalties associated with uncertain tax positions as income tax expense.

	The Company files a consolidated United States federal income tax return. The Company prepares and files tax returns based on the interpretation of tax laws and regulations, and records estimates based on these judgments and interpretations. In the normal course of business, the tax returns are subject to examination by various taxing authorities. Such examinations may result in future tax and interest assessments by these taxing authorities, and the Company records a liability when it is probable that there will be an assessment. The Company adjusts the estimates periodically as a result of ongoing examinations by and settlements with the various taxing authorities, and changes in tax laws, regulations and precedent. The consolidated tax provision of any given year includes adjustments to prior years’ income tax accruals that are considered appropriate, and any related estimated interest. Management believes that adequate accruals have been made for income taxes. Differences between estimated and actual amounts determined upon ultimate resolution, individually or in the aggregate, are not expected to have a material effect on the Company’s consolidated financial position, but could possibly be material to its consolidated results of operations or cash flow of any one period.

Engineering Development	'
	Engineering Development

	Total engineering development expense is comprised of both internally funded research and development (“R&D”) and product development and design charges related to specific customer EDC. Engineering development expense consists primarily of payroll-related expenses of employees engaged in EDC, engineering related product materials and equipment and subcontracting costs. R&D charges incurred for product design, product enhancements and future product development are expensed as incurred. Product development and design charges related to specific customer EDC are charged to cost of sales-EDC.

Comprehensive Income	'
	Comprehensive Income

	Pursuant to FASB ASC Topic 220, “Comprehensive Income” (“ASC Topic 220”), the Company is required to classify items of other comprehensive income by their nature in a financial statement and display the accumulated balance of other comprehensive income separately from retained earnings and additional paid-in capital in the equity section of its condensed consolidated balance sheets. For fiscal 2013, 2012 and 2011 comprehensive income consisted of net income only, and there were no items of other comprehensive income for any of the periods presented.

Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments

	The net carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and short-term debt approximate their fair value because of the short-term nature of these instruments. For financial assets and liabilities measured at fair value on a recurring basis, fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value as follows:

	Level 1 — Unadjusted quoted prices that are available in active markets for the identical assets or liabilities at the measurement date.

	Level 2 — Other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly, including:

	· Quoted prices for similar assets or liabilities in active markets;
	· Quoted prices for identical or similar assets in non-active markets;
	· Inputs other than quoted prices that are observable for the asset or liability; and
	· Inputs that are derived principally from or corroborated by other observable market data.

	Level 3 — Unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.

	The following table sets forth by level within the fair value hierarchy the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2013 and 2012, according to the valuation techniques the Company used to determine their fair values.

Share-Based Compensation	'
	Share-Based Compensation

	The Company accounts for share-based compensation under FASB ASC Topic 505-50, “Equity-Based Payments to Non-Employees” (“ASC Topic 505-50”) and ASC Topic 718, “Stock Compensation” (“ASC Topic 718”), which requires the Company to measure the cost of employee or non-employee director services received in exchange for an award of equity instruments based on the grant-date fair value of the award using an option pricing model. That cost is recognized over the period during which an employee or non-employee director is required to provide service in exchange for the award.

Warranty	'
	Warranty

	The Company offers warranties on some products of various lengths. At the time of shipment, and when sold separately, the Company establishes a reserve for estimated costs of warranties based on its best estimate of the amounts necessary to settle future and existing claims using historical data on products sold as of the balance sheet date. The length of the warranty period, the product’s failure rates, and the customer’s usage affect warranty cost. If actual warranty costs differ from the Company’s estimated amounts, future results of operations could be affected adversely. Warranty cost is recorded as cost of sales, and the reserve balance recorded as an accrued expense. While the Company maintains product quality programs and processes, its warranty obligation is affected by product failure rates and the related corrective costs. If actual product failure rates and/or corrective costs differ from the estimates, the Company revises estimated warranty liability accordingly.

New Accounting Pronouncements	'
	New Accounting Pronouncements

	In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (“ASU 2013-11”). ASU 2013-11 provides that a liability related to an unrecognized tax benefit should be offset against a deferred tax asset for a NOL carryforward, a similar tax loss or a tax credit carryforward if such liability is to be settled by reducing an available tax carryforward in the event the uncertain tax position is disallowed. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 for public entities, with early adoption permitted. The adoption of ASU 2013-11 during the fourth quarter of fiscal year ending September 20, 2013 did not have a material impact on the Company’s consolidated financial statements.

	In May 2011, the FASB issued ASU 2011-04, “Fair Value Measurement (Topic 820), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (“ASU 2011-04”). ASU 2011-04 amends the fair value measurement and disclosure guidance to converge accounting principles generally accepted in the United States of America (“GAAP”) and International Financial Reporting Standards (“IFRS”) requirements for measuring amounts at fair value as well as disclosures about these measurements. ASU 2011-04 was to be adopted prospectively and was effective for the interim and annual periods beginning after December 15, 2011. The adoption of ASU 2011-04 did not have a material impact on the Company’s consolidated financial statements.

	In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (“ASU 2011-05”) which requires that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement would present total net income and its components followed consecutively by a second statement that would present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. ASU 2011-05 is to be adopted retrospectively and is effective for annual periods beginning after December 2011. The adoption of ASU 2011-05 did not have an impact on the Company’s consolidated financial position, results of operations, or cash flows, because the guidance changes only the presentation of financial information. In February 2013, the FASB issued ASU 2013-02 requiring the effective date for implementation of the deferred elements of ASU 2011-05 to be effective for reporting periods beginning after December 15, 2012, with early adoption permitted.
