Summary of Significant Accounting Policies |
Summary of Significant Accounting Policies | 1. Summary of Significant Accounting Policies Description of the Company Innovative Solutions and Support, Inc. (the “Company,” “IS&S,” “we” or “us”) was incorporated in Pennsylvania on February 12, 1988. The Company operates in one business segment as a systems integrator that designs, develops, manufactures, sells and services air data equipment, engine display systems, standby equipment, primary flight guidance, autothrottles and cockpit display systems for retrofit applications and original equipment manufacturers (“OEMs”). The Company supplies integrated Flight Management Systems (“FMS”), Flat Panel Display Systems (“FPDS”), FPDS with Autothrottle, air data equipment, Integrated Standby Units (“ISU”), ISU with Autothrottle and advanced Global Positioning System (“GPS”) receivers that enable reduced carbon footprint navigation. The Company has continued to position itself as a system integrator, which capability provides the Company with the potential to generate more substantive orders over a broader product base. This strategy, as both a manufacturer and integrator, is designed to leverage the latest technologies developed for the computer and telecommunications industries into advanced and cost-effective solutions for the general aviation, commercial air transport, United States Department of Defense (“DoD”)/governmental and foreign military markets. This approach, combined with the Company’s industry experience, is designed to enable IS&S to develop high-quality products and systems, to reduce product time to market, and to achieve cost advantages over products offered by its competitors. Basis of Presentation The accompanying unaudited condensed consolidated financial statements are presented pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) in accordance with the disclosure requirements for the quarterly report on Form 10-Q and, therefore, do not include all of the information and footnotes required by generally accepted accounting principles in the United States (“GAAP”) for complete annual financial statements. In the opinion of Company management, the unaudited condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary to state fairly the results for the interim periods presented. The condensed consolidated balance sheet as of September 30, 2021 is derived from the audited financial statements of the Company. Operating results for the three-and six-month periods ended March 31, 2022 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2022, including in terms of the impact of the coronavirus pandemic (the “COVID-19 pandemic”), which cannot be determined at this time. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes of the Company included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2021. Principles of Consolidation The Company’s condensed consolidated financial statements include the accounts of its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Impact of the Russia and Ukraine War The war between Russia and Ukraine and the global response to this war could have an adverse impact on our business and results of operations. Although the war has not had, and is not expected to have, a material impact on our operating results, it is not possible to predict the broader or long-term consequences of the war between Russia and Ukraine, which may include further sanctions, embargoes, regional instability, geopolitical shifts and adverse effects on macroeconomic conditions, cybersecurity conditions, financial markets and energy markets. Such geopolitical instability and uncertainty could have a negative impact on our ability to sell and ship products, collect payments from and support customers in certain regions, and could increase the costs, risks and adverse impacts from supply chain and logistics disruptions. Impact of the COVID-19 Pandemic The ongoing global outbreak of coronavirus, which was declared a pandemic by the World Health Organization on March 11, 2020 and a national emergency by the President of the United States on March 13, 2020, has caused and is continuing to cause business slowdowns and shutdowns and turmoil in the financial markets both in the United States and abroad. IS&S is monitoring the impact of the COVID-19 pandemic on its business, including how it has impacted and will impact the Company’s employees, customers, suppliers and distribution channels. The Company has not yet seen a material impact from the COVID-19 pandemic on its business, financial position, liquidity, or ability to service customers or maintain critical operations. However, the COVID-19 pandemic, as well as the quarantines and other governmental and non‑governmental restrictions which have been imposed throughout the world in an effort to contain or mitigate the spread of the coronavirus (including recent developments as a result of newer variants or strains of SARS‑CoV‑2), have created significant volatility, uncertainty and disruption which may adversely affect IS&S’ business and has caused and is continuing to cause significant market turbulence and disruption that may continue for some time even after business restrictions are lifted and the threat of the coronavirus diminishes. As a result, the Company may face liquidity shortages, weaker product demand from its customers, disruptions in its supply chain, and/or staffing shortages in its workforce for the foreseeable future due to the direct and indirect effects of the COVID-19 pandemic. 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 Engineering Development Contract (“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 statements 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 March 31, 2022 and September 30, 2021 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 net realizable value, net of write-downs for excess and obsolete inventory. Property and Equipment Property and equipment are stated at cost. Depreciation is provided using an accelerated method over the estimated useful lives of the assets (the lesser of three to seven years or over the lease term), except for the manufacturing facility and the corporate airplanes, which are depreciated using the straight-line method over their estimated useful lives of thirty-nine years and ten years, respectively. 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 during the three-and six-month periods ended March 31, 2022 or 2021. 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 March 31, 2022 and September 30, 2021, according to the valuation techniques the Company used to determine their fair values. ​

​ 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, autothrottles 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. Revenue from Contracts with Customers The Company accounts for revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). The core principle of ASC 606 is that an entity recognizes revenue when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these goods or services. To achieve this core principle, the Company applies the following five steps:
| 1) | Identify the contract with a customer
The Company’s contract with its customers typically is the form of a purchase order issued to the Company by its customers and, to a lesser degree, in the form of a purchase order issued in connection with a formal contract executed with a customer. For the purpose of accounting for revenue under ASC 606, a contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the payment terms related to these goods or services, (ii) the contract has commercial substance and, (iii) the Company determines that collection of substantially all consideration for goods or services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. The Company applies judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the customer.
| 2) | Identify the performance obligations in the contract
Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the goods or services is separately identifiable from other promises in the contract. Most of our revenue is derived from purchases under which we provide a specific product or service and, as a result, there is only one performance obligation. In the event that a contract includes multiple promised goods or services, such as an EDC contract which includes both engineering services and a resulting product shipment, the Company must apply judgment to determine whether promised goods or services are capable of being distinct in the context of the contract. In these cases, the Company considers whether the customer could, on its own, or together with other resources that are readily available from third parties, produce the physical product using only the output resulting from the Company’s completion of engineering services. If the customer cannot produce the physical product, then the promised goods or services are accounted for as a combined performance obligation.
| 3) | Determine the transaction price
The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring goods or services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur.
| 4) | Allocate the transaction price to performance obligations in the contract
If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. The Company determines standalone selling price based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price by taking into account available information such as market conditions as well as the cost of the goods or services and the Company’s normal margins for similar performance obligations.
| 5) | Recognize revenue when or as the Company satisfies a performance obligation
The Company satisfies performance obligations either over time or at a point in time as discussed in further detail below. Revenue is recognized at the time the related performance obligation is satisfied by transferring a promised good or service to a customer. Revenue from products transferred to customers at a point in time accounted for 100 percent of our revenue for the three-and six-month periods ended March 31, 2022 and 2021, respectively, and is typically recognized at the time of shipment of products to the customer. The remaining revenue results from EDC contracts and is recognized over time using an input measure (e.g., costs incurred to date relative to total estimated costs at completion) to measure progress. Contract costs include material, components and third-party avionics purchased from suppliers, direct labor, and overhead costs. Contract Estimates Accounting for performance obligations in long-term contracts that are satisfied over time involves the use of various techniques to estimate progress towards satisfaction of the performance obligation. The Company typically measures progress based on costs incurred compared to estimated total contract costs. Contract cost estimates are based on various assumptions to project the outcome of future events that often span more than a single year. These assumptions include the amount of labor and labor costs, the quantity and cost of raw materials used in the completion of the performance obligation, and the complexity of the work to be performed. As a significant change in one or more of these estimates could affect the profitability of our contracts, we review and update our contract-related estimates regularly. We recognize adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize the total loss in the quarter it is identified. The impact of adjustments in contract estimates on our operating earnings can be reflected in either operating costs and expenses or revenue. The aggregate impact of adjustments in contract estimates did not change our revenue and operating earnings (and diluted earnings per share) for the three-and six-month periods ended March 31, 2022 and 2021, respectively. Therefore, no adjustment on any contract was material to our unaudited consolidated financial statements for the three-and six-month periods ended March 31, 2022 and 2021, respectively. Contract Balances Contract assets consist of the right to consideration in exchange for product offerings that we have transferred to a customer under the contract. Contract liabilities primarily relate to consideration received in advance of performance under the contract. The following table reflects the Company’s contract assets and contract liabilities: ​

​ Customer Service Revenue The Company enters into sales arrangements with customers for the repair or upgrade of its various products that are not under warranty. The Company’s customer service revenue and cost of sales are included in product sales and product cost of sales, respectively, on the accompanying consolidated statements of operations. The Company’s customer service revenue and cost of sales for the three-and six-month periods ended March 31, 2022 and 2021 respectively are as follows: ​

​ Lease Recognition The Company accounts for leases in accordance with ASU 2016-02, Leases (Topic 842). At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present in the arrangement. Leases with a term greater than one year are recognized on the balance sheet as right-of-use assets and short-term and long-term lease liabilities, as applicable. The Company does not have any financing leases that are material in nature. Income Taxes Income taxes are recorded in accordance with 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 NOLs and tax credit carryforwards. 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. At the end of each interim reporting period, the Company prepares an estimate of the annual effective income tax rate and applies that annual effective income tax rate to ordinary year-to-date pre-tax income for the interim period. Specific tax items discrete to a particular quarter are recorded in income tax expense for that quarter. The estimated annual effective tax rate used in providing for income taxes on a year-to-date basis may change in subsequent periods. Deferred tax assets are reduced by a valuation allowance 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 allowance recorded against net deferred tax assets. The Company evaluates deferred income taxes on a quarterly basis to determine if a valuation allowance is 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 carryforwards, taxable income in carry-back years, and tax planning strategies which are both prudent and feasible. For the quarter ended June 30, 2021, the valuation allowance was released for all federal and some state deferred tax assets. This release both increased the deferred tax asset and removed the valuation allowance. The Company will continue to assess all available evidence during future periods to evaluate any changes to the realization of its deferred tax assets.If the Company were to determine that it would be able to realize additional state deferred tax assets in the future, it would make an adjustment to the valuation allowance which would reduce the provision for 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 U.S. 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 it has made adequate accruals 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 The Company invests a significant percentage of its sales on engineering development, both Research & Development (“R&D”) and EDC. At March 31, 2022, approximately 19% of the Company’s employees were engineers engaged in various engineering development projects. Total engineering development expense comprises 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 EDC 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-EDC based on the method of contract accounting (either percentage-of-completion or completed contract) applicable to such contracts. Treasury Stock We account for treasury stock purchased under the cost method and include treasury stock as a component of shareholders’ equity. Treasury stock purchased with intent to retire (whether or not the retirement is actually accomplished) is charged to common stock. Comprehensive Income Pursuant to FASB ASC Topic 220, “Comprehensive Income,” 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 the three-and six-month periods ended March 31, 2022 and 2021, comprehensive income consisted of net income only, and there were no items of other comprehensive income for any of the periods presented. Share-Based Compensation The Company accounts for share-based compensation under 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. The Company recognizes such cost over the period during which an employee or non-employee director is required to provide service in exchange for the award. Accordingly, adoption of ASC Topic 718’s fair value method results in recording compensation costs under the Company’s stock-based compensation plans. The Company determined the fair value of its stock option awards at the date of grant using the Black-Scholes option pricing model. Option pricing models and generally accepted valuation techniques require management to make assumptions and to apply judgment to determine the fair value of its awards. These assumptions and judgments include estimating future volatility of the Company’s stock price, expected dividend yield, future employee turnover rates, and future employee stock option exercise behaviors. Changes in these assumptions can materially affect fair value estimates. The Company does not believe that a reasonable likelihood exists that there will be a material change in future estimates or assumptions used to determine share-based compensation expense. However, if actual results are not consistent with the Company’s estimates or assumptions, the Company would adjust its estimates. Such adjustments could have a material impact on the Company’s financial position. Warranty Reserves The Company offers warranties on some products of various lengths, however the standard warranty period is twenty-four months. At the time of shipment, 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 the estimated warranty liability accordingly. Self-Insurance Reserves Since January 1, 2014, the Company has self-insured a significant portion of its employee medical insurance. The Company maintains a stop-loss insurance policy that limits its losses both on a per employee basis and an aggregate basis. Liabilities associated with the risks that are retained by the Company are estimated based upon actuarial assumptions such as historical claims experience and demographic factors. The Company estimated the total medical claims incurred but not reported and the Company believes that it has adequate reserves for these claims at March 31, 2022 and September 30, 2021, respectively. However, the actual value of such claims could be significantly affected if future occurrences and claims differ from these assumptions. At March 31, 2022 and September 30, 2021, the estimated liability for medical claims incurred but not reported was $59,859 and $55,934, respectively. The Company has recorded the excess of funded premiums over estimated claims incurred but not reported of $233,567 and $208,651 as a current asset in the accompanying condensed consolidated balance sheets as of March 31, 2022 and September 30, 2021, respectively. Concentrations Major Customers and Products In the three-month period ended March 31, 2022, three customers, Pilatus Aircraft Ltd (“Pilatus”), Amazon.com and Textron Aviation, Inc. (“Textron”), accounted for 29%, 11% and 10% of net sales, respectively. In the six-month period ended March 31, 2022, two customers, Pilatus, and Air Transport Services Group, accounted for 26%, and 13% of net sales, respectively. In the three-month period ended March 31, 2021, two customers, Pilatus, and Textron, accounted for 25%, and 16% of net sales, respectively. In the six-month period ended March 31, 2021, three customers, Pilatus, Textron, and Sierra Nevada Corporation, accounted for 17%, 14% and 12% of net sales, respectively. 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. For the three- and six-month periods ended March 31, 2022, the Company had three suppliers, respectively that were individually responsible for greater than 10% of the Company’s total inventory related purchases. For the three- and six-month periods ended March 31, 2021, the Company had one and two suppliers, respectively that were individually responsible for greater than 10% of the Company’s total inventory related 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. Cash balances are maintained with two major banks. Balances on deposit with certain money market accounts and operating accounts may exceed the Federal Deposit Insurance Corporation limits. The Company’s customer base consists principally of companies within the aviation industry. The Company requests advance payments and/or letters of credit from customers that it considers to be credit risks. Recent Accounting Pronouncements In June 2016, FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instrument (“ASU 2016-13”). ASU 2016-13 replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is effective for SEC small business filers for fiscal years beginning after December 15, 2022. Management is currently assessing the impact ASU 2016-13 will have on the Company. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”), which simplifies the accounting for income taxes, eliminates certain exceptions within Accounting Standards Codification Topic 740, “Income Taxes” (“ASC 740”), and clarifies certain aspects of ASC 740 to promote consistency among reporting entities. We adopted this update effective October 1, 2021. The adoption of this standard did not have a material impact on our condensed consolidated financial statements or related disclosures. As new accounting pronouncements are issued, we will adopt those that are applicable.
