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

Preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used in accounting for, among other items, allowance for doubtful accounts, inventory obsolescence, product warranty cost liability, income taxes, percentage of completion on customer funded EMD contracts, and contingencies. Actual results could differ materially from those estimates.

Highly liquid investments purchased with an original maturity of three months or less are classified as cash equivalents. Cash equivalents at September 30, 2012 and 2011 consist of cash invested in money market funds with financial institutions.

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

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 2012, 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.

The Company assesses the impairment of long-lived assets in accordance with FASB 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 2012, 2011 or 2010.

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 customer funded design, EMD services, and production and delivery of the flat panel display and related components. The Company includes any design and EMD elements in EMD sales, and any functional upgrades and product elements in product sales on 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 No. 2009-14, "Revenue Arrangements That Include Software Elements" ("ASU 2009-14"), 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 are sold on a standalone basis and which the Company has deemed outside the scope of the exception defined by ASU 2009-14, the Company recognizes software revenue in accordance with ASC Topic 985, "Software", although no such sales have occurred to date.

The Company identifies all goods and/or services that are to be delivered separately under such a sales arrangement and allocates revenue 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 EMD activities and/or functional upgrades, along with product sales.

The Company utilizes the selling price hierarchy that has been established by FASB Accounting Standards Update No. 2009-13, "Multiple Deliverable Revenue Arrangements—a consensus of the FASB Emerging Issues Task Force" ("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 would be used to determine the price to sell the deliverable on a standalone basis.

To the extent that an arrangement contains defined design and EMD activities as an identified deliverable in addition to products (resulting in a multiple element arrangement), the Company recognizes as EMD revenue amounts earned during the design and EMD 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, the Company recognizes revenue when revenue recognition criteria for the product deliverable have been met based on the provisions of ASC Topic 605. The Company includes any design and engineering services elements in EMD sales, and any functional upgrades and product elements in product sales on the accompanying consolidated statement of operations.

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

The Company offers 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.

The Company may enter into contracts to perform specified design and EMD services related to its products. The Company recognizes revenue from these arrangements as EMD revenue, following the guidance included in ASC Topic 605-35, and considers the nature of these contracts (including term, size of contract, 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 reasonable and reliably estimable, and the contract is long-term in nature. The Company uses the completed contract method for all others contracts. Sales and earnings 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, and to apply that profit margin on a uniform basis as sales are recorded under the contract. The estimation of profit margins 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 and cost, overhead and capital costs. These contracts sometime include purchase options for additional quantities and customer change orders for additional or revised product functionality. Sales and costs related to profitable purchase options are included in the Company's estimates only when the options are exercised, while sales and costs related to unprofitable purchase options are included in the Company's estimates when exercise is determined to be probable. Sales 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. 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 FASB ASC Topic 605-35.

Estimates of profit margins for contracts are reviewed typically by the Company on a quarterly basis. Assuming the initial estimates of sales 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 sales 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 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 estimate is made. Cumulative catch-up adjustments resulting from changes in estimates did not have a material effect on our results of operations during the years ended September 30, 2012, 2011 or 2010.

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 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 are possible. The current balance of the deferred tax valuation allowance relates principally to net operating losses ("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.

Total engineering development expense is comprised of both internally funded R&D and product development and design charges related to specific customer contracts. Engineering development expense consists primarily of payroll-related expenses of employees engaged in engineering development projects, 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 contracts are charged to cost of sales-engineering modification and development based on the method of contract accounting (either percentage of completion or completed contract) applicable to such contracts.

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 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.

The net carrying amounts of cash and cash equivalents, accounts receivable, cash overdraft, accounts payable and short-term debt approximate their fair value due to 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, 2012 and 2011, according to the valuation techniques the Company used to determine their fair values.

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 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 is required to provide service in exchange for the award.

IS&S offers warranties on all products of various lengths. At the time of shipment, the Company establishes a reserve for 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 adversely affected. 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.

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 GAAP and 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 will not have an impact on the Company's consolidated financial position, results of operations, or cash flows, because the guidance only changes the presentation of financial information. In December 15, 2011, the FASB issued ASU 2011-12 deferring the effective date for implementation of ASU 2011-05 related only to reclassification out of accumulated other comprehensive income until a later date to be determined after further consideration by the FASB.
