Nature of Business and Summary of Significant Accounting Policies
Nature of Business and Summary of Significant Accounting Policies	NOTE 1 - Nature of Business and Summary of Significant Accounting Policies Nature of Business : Napco Security Technologies, Inc. (“NAPCO”, “the Company”, “we”) is one of the leading manufacturers and designers of high-tech electronic security devices, wireless recurring communication services for intrusion and fire alarm systems as well as a leading provider of school safety solutions. We offer a diversified array of security products, encompassing access control systems, door-locking products, intrusion and fire alarm systems and video surveillance products. These products are used for commercial, residential, institutional, industrial and governmental applications, and are sold worldwide principally to independent distributors, dealers and installers of security equipment. We have experienced significant growth in recent years, primarily driven by fast growing recurring service revenues generated from wireless communication services for intrusion and fire alarm systems, as well as our school security products that are designed to meet the increasing needs to enhance school security as a result of on-campus shooting and violence in the U.S. The Company’s fiscal year begins on July 1 and ends on June 30. Historically, the end users of the Company’s equipment products want to install these products prior to the summer; therefore, sales of these products historically peak in the period April 1 through June 30, the Company’s fiscal fourth quarter, and are reduced in the period July 1 through September 30, the Company’s fiscal first quarter. In addition, demand for our products is affected by the housing and construction markets. Deterioration of the current economic conditions may also affect this trend. Our results for fiscal 2021 and the first two quarters of fiscal 2022 reflected the increase in customer demand after the challenging business environment resulting from the COVID-19 pandemic. While the Company believes this recovery will continue, there can be no assurances that it will do so in the event of a return to building and construction restrictions that might result from a return to higher levels of COVID-19 cases. Significant Accounting Policies: Principles of Consolidation The consolidated financial statements include the accounts of Napco Security Technologies, Inc. and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation. Stock Split In December 2021, the Company's Board of Directors approved a two -for-one stock split in the form of a 100% stock dividend of the Company’s common stock payable to stockholders of record on December 20, 2021. The additional shares were distributed on January 4, 2022. All share and per share amounts (except par value) have been retroactively adjusted to reflect the stock split. There was no net effect on total stockholders' equity as a result of the stock split. Upon distribution of the dividend, the total number of shares outstanding increased from 18,365,878 to 36,731,756 . Accounting Estimates The preparation of financial statements in conformity with Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent gains and losses at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Critical estimates include management’s judgments associated with reserves for sales returns and allowances, allowance for doubtful accounts, inventory reserves, valuation of intangible assets and income taxes. Actual results could differ from those estimates. Fair Value of Financial Instruments The methods and assumptions used to estimate the fair value of the following classes of financial instruments were: Current Assets and Current Liabilities - The carrying amount of cash and cash equivalents, certificates of deposits, current receivables and payables and certain other short-term financial instruments approximate their fair value as of December 31, 2021 and June 30, 2021 due to their short-term maturities. Long-term debt and lease liabilities reflect fair value based on prevailing market rates. Cash and Cash Equivalents Cash and cash equivalents include approximately $63,000 of short-term time deposits at both December 31, 2021 and June 30, 2021, respectively. The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company has cash balances in banks in excess of the maximum amount insured by the FDIC and other international agencies as of December 31, 2021 and June 30, 2021. The Company has not historically experienced any credit losses with balances in excess of FDIC limits. Marketable Securities The Company’s marketable securities include investments in mutual funds, which invest primarily in various government and corporate obligations, stocks and money market funds. The Company’s marketable securities are reported at fair value with the related unrealized and realized gains and losses included in other expense (income). Realized gains or losses on mutual funds are determined on a specific identification basis. The Company would record an impairment charge if the cost of the available-for-sale securities exceeds the estimated fair value of the securities and the decline in value is determined to be other-than-temporary. During the three and six months ended December 31, 2021, the Company did not record an impairment charge regarding its investment in marketable securities because management believes, based on its evaluation of the circumstances, that the decline in fair value below the cost of certain of the Company’s marketable securities is temporary. Accounts Receivable Accounts receivable is stated net of the reserves for doubtful accounts of $226,000 as of December 31, 2021 and June 30, 2021, respectively. Our reserves for doubtful accounts are subjective critical estimates that have a direct impact on reported net earnings. These reserves are based upon the evaluation of our accounts receivable aging, specific exposures, sales levels and historical trends. Inventories Inventories are valued at the lower of cost or net realizable value, with cost being determined on the first-in, first-out (FIFO) method. The reported net value of inventory includes finished saleable products, work-in-process and raw materials that will be sold or used in future periods. Inventory costs include raw materials, direct labor and overhead. The Company’s overhead expenses are applied based, in part, upon estimates of the proportion of those expenses that are related to procuring and storing raw materials as compared to the manufacture and assembly of finished products. These proportions, the method of their application, and the resulting overhead included in ending inventory, are based in part on subjective estimates and actual results could differ from those estimates. In addition, the Company records an inventory obsolescence reserve, which represents any excess of the cost of the inventory over its estimated realizable value, based on various product sales projections. This reserve is calculated using an estimated obsolescence percentage applied to the inventory based on age, historical trends, requirements to support forecasted sales, and the ability to find alternate applications of its raw materials and to convert finished product into alternate versions of the same product to better match customer demand. In addition, and as necessary, the Company may establish specific reserves for future known or anticipated events. There is inherent professional judgment and subjectivity made by both production and engineering members of management in determining the estimated obsolescence percentage. The Company also regularly reviews the period over which its inventories will be converted to sales. Any inventories expected to convert to sales beyond 12 months from the balance sheet date are classified as non-current. Property, Plant, and Equipment Property, plant, and equipment are carried at cost less accumulated depreciation. Expenditures for maintenance and repairs are charged to expense as incurred; costs of major renewals and improvements are capitalized. At the time property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are eliminated from the asset and accumulated depreciation accounts and the profit or loss on such disposition is reflected in income. Depreciation is recorded over the estimated service lives of the related assets using primarily the straight-line method. Amortization of leasehold improvements is calculated by using the straight-line method over the estimated useful life of the asset or lease term, whichever is shorter. Long-Lived and Intangible Assets Long-lived assets are amortized over their useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets in question may not be recoverable. Impairment would be recorded in circumstances where undiscounted cash flows expected to be generated by an asset are less than the carrying value of that asset. Intangible assets determined to have indefinite lives were not amortized but were tested for impairment at least annually. The Company’s acquisition of substantially all of the assets and certain liabilities of G. Marks Hardware, Inc. (“Marks”) in August 2008 included intangible assets recorded at fair value on the date of acquisition. The customer relationships are amortized over their estimated useful lives of twenty years. At the acquisition date, the Marks trade name was deemed to have an indefinite life. During the 4th quarter of fiscal 2020, the Company determined that the trade-name was impaired. Accordingly, the Company recorded an impairment charge of $1,852,000 and reclassified the remaining balance of the underlying asset from indefinite-lived to a long-lived asset with a remaining useful life of 20 years as of June 30, 2020. Changes in intangible assets are as follows (in thousands): December 31, 2021 June 30, 2021 Carrying Accumulated Net book Carrying Accumulated Net book value amortization value value amortization value Customer relationships $ 9,800 (9,049) $ 751 $ 9,800 $ (8,955) $ 845 Trade name 4,048 (304) 3,744 4,048 (202) 3,846 $ 13,848 $ (9,353) $ 4,495 $ 13,848 $ (9,157) $ 4,691 Amortization expense for intangible assets subject to amortization was approximately $98,000 and $107,000 for the three months ended December 31, 2021 and 2020, respectively. Amortization expense for intangible assets subject to amortization was approximately $196,000 and $213,000 for the six months ended December 31, 2021 and 2020, respectively. Amortization expense for each of the next five fiscal years is estimated to be as follows: 2022-$390,000; 2023 - $361,000; 2024 - $336,000; 2025 - $315,000; and 2026-$297,000. The weighted average remaining amortization period for intangible assets was 16.5 years and 16.9 years at December 31, 2021 and June 30, 2021, respectively. Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. For product sales, the Company typically transfers control at a point in time upon shipment or delivery of the product. For monthly communication services the Company satisfies its performance obligation as the services are rendered and therefore recognizes revenue over the monthly period. Typically timing of revenue recognition coincides with the timing of invoicing to the customers, at which time the Company has an unconditional right to consideration. As such, the Company typically records a receivable when revenue is recognized. The contract with the customer states the final terms of the sale, including the description, quantity, and price of each product purchased. Payment for product sales is typically due within 30 and 180 days of the delivery date. Payment for monthly communication services is billed on a monthly basis and is typically due at the beginning of the month of service. The Company provides limited standard warranty for defective products, usually for a period of 24 to 36 months. The Company accepts returns for such defective products as well as for other limited circumstances. The Company also provides rebates to customers for meeting specified purchasing targets and other coupons or credits in limited circumstances. The Company establishes reserves for the estimated returns, rebates and credits and measures such variable consideration based on the expected value method using an analysis of historical data. Changes to the estimated variable consideration in subsequent periods are not material. The Company analyzes sales returns and is able to make reasonable and reliable estimates of product returns based on the Company’s past history. Estimates for sales returns are based on several factors including actual returns and based on expected return data communicated to it by its customers. Accordingly, the Company believes that its historical returns analysis is an accurate basis for its allowance for sales returns. Actual results could differ from those estimates. Advertising and Promotional Costs Advertising and promotional costs are included in "Selling, General and Administrative" expenses in the consolidated statements of income and are expensed as incurred. Advertising expense for the three months ended December 31, 2021 and 2020 was $512,000 and $347,000, respectively. Advertising expense for the six months ended December 31, 2021 and 2020 was $1,598,000 and $690,000, respectively Research and Development Costs Research and development (“R&D”) costs incurred by the Company are charged to expense as incurred and are included in operating expenses in the consolidated statements of income. Company-sponsored R&D expense for the three months ended December 31, 2021 and 2020 was $1,978,000 and $1,884,000, respectively. R&D expense for the six months ended December 31, 2021 and 2020 was $3,909,000 and $3,773,000, respectively. Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred income tax expense represents the change during the period in the deferred tax assets and deferred tax liabilities. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company measures and recognizes the tax implications of positions taken or expected to be taken in its tax returns on an ongoing basis. The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. Net Income per Share Basic net income per common share (Basic EPS) is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per common share (Diluted EPS) is computed by dividing net income by the weighted average number of common shares and dilutive common share equivalents and convertible securities then outstanding. The following provides a reconciliation of information used in calculating the per share amounts for the three months ended December 31, 2021 and 2020 (in thousands, except share and per share data): Net Income Weighted Average Shares Net Income per Share 2021 2020 2021 2020 2021 2020 Basic EPS $ 1,037 $ 3,197 36,728 36,695 $ 0.03 $ 0.09 Effect of Dilutive Securities: Stock Options — — 170 110 — — Diluted EPS $ 1,037 $ 3,197 36,898 36,805 $ 0.03 $ 0.09 Options to purchase 80,435 and 64,000 shares of common stock were excluded for the three months ended December 31, 2021 and 2020, respectively, and were not included in the computation of Diluted EPS because their inclusion would be anti-dilutive. These options were still outstanding at the end of the period. The following provides a reconciliation of information used in calculating the per share amounts for the six months ended December 31, 2021 and 2020 (in thousands, except share and per share data): Weighted Average Net Income per Net Income Shares Share 2021 2020 2021 2020 2021 2020 Basic EPS $ 8,789 $ 5,516 36,720 36,695 $ 0.24 $ 0.15 Effect of Dilutive Securities: Stock Options — — 157 99 — — Diluted EPS $ 8,789 $ 5,516 36,877 36,794 $ 0.24 $ 0.15 Options to purchase 40,217 and 72,000 shares of common stock were excluded for the six months ended December 31, 2021 and 2020, respectively, and were not included in the computation of Diluted EPS because their inclusion would be anti-dilutive. These options were still outstanding at the end of the period. Stock-Based Compensation The Company has established four share incentive programs as discussed in Note 9. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the vesting period. Determining the fair value of share-based awards at the grant date requires assumptions and judgments about expected volatility and forfeiture rates, among other factors. Stock-based compensation costs of $1,255,000 and $84,000 were recognized for the three months ended December 31, 2021 and 2020, respectively. Stock-based compensation costs of $1,344,000 and $188,000 were recognized for the six months ended December 31, 2021 and 2020, respectively. Foreign Currency The Company has determined the functional currency of all foreign subsidiaries is the U.S. Dollar. All foreign operations are considered a direct and integral part or extension of the Company’s operations. The day-to-day operations of all foreign subsidiaries are dependent on the economic environment of the U.S. Dollar. Therefore, no realized and unrealized gains and losses associated with foreign currency translation are recorded for the three or six months ended December 31, 2021 or 2020. Comprehensive Income For the three and six months ended December 31, 2021 and 2020, the Company’s operations did not give rise to material items includable in comprehensive income, which were not already included in net income. Accordingly, the Company’s comprehensive income approximates its net income for all periods presented. Segment Reporting The Company’s reportable operating segments are determined based on the Company’s management approach. The management approach is based on the way that the chief operating decision maker organizes the segments within an enterprise for making operating decisions and assessing performance. The Company’s results of operations are reviewed by the chief operating decision maker on a consolidated basis and the Company operates in only one segment. The Company has presented required geographical data in Note 14. Shipping and Handling Sales and Costs The Company records the amount billed to customers for shipping and handling in net sales ($106,000 and $93,000 in the three months ended December 31, 2021 and 2020, respectively and $212,000 and $199,000 in the six months ended December 31, 2021 and 2020, respectively); and classifies the costs associated with these sales in cost of sales ($361,000 and $230,000 in the three months ended December 31, 2021 and 2020, respectively and $694,000 and $451,000 in the six months ended December 31, 2021 and 2020, respectively). Leases Effective July 1, 2019, the Company adopted the new lease accounting standard using the modified retrospective transition option of applying the new standard at the adoption date. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to not reassess (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases, and (3) initial direct costs for any existing leases. Adoption of the new standard resulted in the recording of an operating ROU asset and lease liabilities Recently Issued Accounting Standards Reference Rate Reform (ASC Topic 848) In March 2020, the FASB issued authoritative guidance to provide optional relief for companies preparing for the discontinuation of interest rates such as the London Interbank Offered Rate (“LIBOR”), which is expected to be phased out at the end of calendar 2021, and applies to lease contracts, hedging instruments, held-to-maturity debt securities and debt arrangements that have LIBOR as the benchmark rate. In January 2021, the FASB issued authoritative guidance that makes amendments to the new rules on accounting for reference rate reform. The amendments clarify that for all derivative instruments affected by the changes to interest rates used for discounting, margining or contract price alignment, regardless of whether they reference LIBOR or another rate expected to be discontinued as a result of reference rate reform, an entity may apply certain practical expedients in ASC Topic 848. Effective for the Company – This guidance can be applied for a limited time through December 31, 2022. The guidance will no longer be available to apply after December 31, 2022. Impact on consolidated financial statements – The Company is currently assessing the impact of applying this guidance on its existing derivative contracts, leases and other arrangements, as well as when to adopt this guidance.

Marketable Securities	NOTE 4 – Marketable Securities The Company’s marketable securities include investments in mutual funds, which invest primarily in various government and corporate obligations, stocks and money market funds, and are reported at their fair values. There were no realized or unrealized gains and losses for the three months or six month ended December 31, 2020. The disaggregated net gains and losses on the marketable securities recognized within the accompanying condensed consolidated statements of income for the three and six months ended December 31, 2021, are as follows (in thousands): Three months ended December 31, 2021 Six months ended December 31, 2021 Net gains recognized during the period on marketable securities $ 21 $ 40 Less: Net gains recognized during the year on marketable securities sold during the period — — Unrealized (losses) gains recognized during the reporting year on marketable securities still held at the reporting date (39) (36) $ (18) $ 4 The fair values of the Company’s marketable securities are determined as being the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company utilizes the three-tier value hierarchy, as prescribed by US GAAP, which prioritizes the inputs used in measuring fair value as follows: • Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement. The Company’s marketable securities, which are considered available-for-sale securities, are re-measured to fair value on a recurring basis and are valued using Level 1 inputs using quoted prices (unadjusted) for identical assets in active markets. The following tables summarize the Company’s investments at December 31, 2021 and June 30, 2021, respectively (in thousands): December 31, 2021 June 30, 2021 Unrealized Unrealized Cost Fair Value Gain (Loss) Cost Fair Value Gain (Loss) Marketable Securities $ 5,462 $ 5,417 $ (45) $ 5,422 $ 5,413 $ (9) Investment income is recognized when earned and consists principally of interest income from fixed income mutual funds.

Income Taxes
Income Taxes	NOTE 7 - Income Taxes The provision for income taxes represents Federal, foreign, and state and local income taxes. The effective rate differs from statutory rates due to the effect of state and local income taxes, tax rates in foreign jurisdictions, global intangible low-taxed income (“GILTI”), tax benefit of R&D credits, a gain on extinguishment of debt of the Company’s PPP loans and certain nondeductible expenses. Our effective tax rate will change from quarter to quarter based on recurring and non-recurring factors including, but not limited to, the geographical mix of earnings, enacted tax legislation, and state and local income taxes. In addition, changes in judgment from the evaluation of new information resulting in the recognition de-recognition or re-measurement of a tax position taken in a prior annual period is recognized separately in the quarter of the change. For the six months ended December 31, 2021, the Company recognized net income tax expense of $639,000. During the six months ended December 31, 2021, the Company’s reserve for uncertain income tax positions increased by $6,000. The Company’s practice is to recognize interest and penalties related to income tax matters in income tax expense and accrued income taxes. As of December 31, 2021, the Company had accrued interest totaling $76,000, as well as $678,000 of unrecognized net tax benefits that, if recognized, would favorably affect the Company’s effective income tax rate in any future period. For the six months ended December 31, 2021, additional interest expense was accrued for in the amount of $6,000. The Company claims R&D tax credits on eligible R&D expenditures. The R&D tax credits are recognized as a reduction to income tax expense. The Company does not expect that our unrecognized tax benefits will significantly change within the next twelve months. We file a consolidated U.S. income tax return and tax returns in certain state and local and foreign jurisdictions. As of December 31, 2021, we remain subject to examination in all tax jurisdictions for all relevant jurisdictional statutes for fiscal years 2018 and thereafter. The Company was audited by the IRS for fiscal year 2016. During fiscal year 2020, the Company settled the issue at Appeals and recorded a provision for the federal and state impact of $762,000 and $70,000 respectively. As of March 31, 2021, all federal and state liabilities related to the fiscal year 2016 audit have been paid. The Company was audited by the IRS for the fiscal year 2017. During the third quarter of fiscal 2021, the Company settled the issue and paid the IRS $399,000. The Company reported the results of the IRS exam to all the jurisdictions in which it files and paid taxes and interest totaling $97,000. In fiscal 2021, the Company paid the IRS $68,000 for interest. None of the payments were recorded to expense since adequate liabilities had previously been established. The Company has identified its U.S. Federal income tax return and its State return in New York as its major tax jurisdictions. In January 2022, the Company received a letter from the IRS (“IRS”) notifying it that the IRS would be examining the Company’s income tax return for fiscal year ended June 30, 2020. Management believes that its provision for income taxes for this period is adequate. However, the outcome cannot be predicted with certainty.

The Company’s obligations under the Revolver Agreement continue to be secured by substantially all of its domestic assets, including but not limited to, deposit accounts, accounts receivable, inventory, equipment and fixtures and intangible assets. In addition, the Company’s wholly owned subsidiaries, with the exception of the Company’s foreign subsidiaries, have issued guarantees and pledges of all of their assets to secure the Company’s obligations under the Revolver Agreement. All of the outstanding common stock of the Company’s domestic subsidiaries and 65% of the common stock of the Company’s foreign subsidiaries has been pledged to secure the Company’s obligations under the Revolver Agreement.

Stock Option	NOTE 9 - Stock Option The Company follows ASC 718 (“Share-Based Payment”), which requires that all share-based payments to employees, including stock options, be recognized as compensation expense in the consolidated financial statements based on their fair values and over the requisite service period. For the three months ended December 31, 2021 and 2020, the Company recorded non-cash compensation expense of $1,255,000 ($0.03 per basic and diluted share) and $84,000 ($0.00 per basic and diluted share), respectively, relating to stock-based compensation.

The 2012 Employee Plan authorizes the granting of awards, the exercise of which would allow up to an aggregate of 1,900,000 shares of the Company’s common stock to be acquired by the holders of such awards. Under this plan, the Company may grant stock options, which are intended to qualify as incentive stock options (ISOs) or non-incentive stock options, to valued employees. Any plan participant who is granted ISOs and possesses more than 10% of the voting rights of the Company’s outstanding common stock must be granted an option with a price of at least 110% of the fair market value on the date of grant. Under the 2012 Employee Plan, stock options may be granted to valued employees with a term of up to 10 years at an exercise price equal to or greater than the fair market value on the date of grant and are exercisable, in whole or in part, at 20% per year beginning on the date of grant. An option granted under this plan shall vest in full upon a “change in control” as defined in the plan. At December 31, 2021, 524,080 stock options were outstanding, 160,576 stock options were exercisable and 1,138,920 stock options were available for grant under this plan.

Nature of Business and Summar_2

Nature of Business and Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Dec. 31, 2021
Nature of Business and Summary of Significant Accounting Policies
Nature of Business	Nature of Business : Napco Security Technologies, Inc. (“NAPCO”, “the Company”, “we”) is one of the leading manufacturers and designers of high-tech electronic security devices, wireless recurring communication services for intrusion and fire alarm systems as well as a leading provider of school safety solutions. We offer a diversified array of security products, encompassing access control systems, door-locking products, intrusion and fire alarm systems and video surveillance products. These products are used for commercial, residential, institutional, industrial and governmental applications, and are sold worldwide principally to independent distributors, dealers and installers of security equipment. We have experienced significant growth in recent years, primarily driven by fast growing recurring service revenues generated from wireless communication services for intrusion and fire alarm systems, as well as our school security products that are designed to meet the increasing needs to enhance school security as a result of on-campus shooting and violence in the U.S. The Company’s fiscal year begins on July 1 and ends on June 30. Historically, the end users of the Company’s equipment products want to install these products prior to the summer; therefore, sales of these products historically peak in the period April 1 through June 30, the Company’s fiscal fourth quarter, and are reduced in the period July 1 through September 30, the Company’s fiscal first quarter. In addition, demand for our products is affected by the housing and construction markets. Deterioration of the current economic conditions may also affect this trend. Our results for fiscal 2021 and the first two quarters of fiscal 2022 reflected the increase in customer demand after the challenging business environment resulting from the COVID-19 pandemic. While the Company believes this recovery will continue, there can be no assurances that it will do so in the event of a return to building and construction restrictions that might result from a return to higher levels of COVID-19 cases.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Napco Security Technologies, Inc. and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation.
Stock Split	Stock Split In December 2021, the Company's Board of Directors approved a two -for-one stock split in the form of a 100% stock dividend of the Company’s common stock payable to stockholders of record on December 20, 2021. The additional shares were distributed on January 4, 2022. All share and per share amounts (except par value) have been retroactively adjusted to reflect the stock split. There was no net effect on total stockholders' equity as a result of the stock split. Upon distribution of the dividend, the total number of shares outstanding increased from 18,365,878 to 36,731,756 .
Accounting Estimates	Accounting Estimates The preparation of financial statements in conformity with Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent gains and losses at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Critical estimates include management’s judgments associated with reserves for sales returns and allowances, allowance for doubtful accounts, inventory reserves, valuation of intangible assets and income taxes. Actual results could differ from those estimates.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The methods and assumptions used to estimate the fair value of the following classes of financial instruments were: Current Assets and Current Liabilities - The carrying amount of cash and cash equivalents, certificates of deposits, current receivables and payables and certain other short-term financial instruments approximate their fair value as of December 31, 2021 and June 30, 2021 due to their short-term maturities. Long-term debt and lease liabilities reflect fair value based on prevailing market rates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include approximately $63,000 of short-term time deposits at both December 31, 2021 and June 30, 2021, respectively. The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company has cash balances in banks in excess of the maximum amount insured by the FDIC and other international agencies as of December 31, 2021 and June 30, 2021. The Company has not historically experienced any credit losses with balances in excess of FDIC limits.
Marketable Securities.	Marketable Securities The Company’s marketable securities include investments in mutual funds, which invest primarily in various government and corporate obligations, stocks and money market funds. The Company’s marketable securities are reported at fair value with the related unrealized and realized gains and losses included in other expense (income). Realized gains or losses on mutual funds are determined on a specific identification basis. The Company would record an impairment charge if the cost of the available-for-sale securities exceeds the estimated fair value of the securities and the decline in value is determined to be other-than-temporary. During the three and six months ended December 31, 2021, the Company did not record an impairment charge regarding its investment in marketable securities because management believes, based on its evaluation of the circumstances, that the decline in fair value below the cost of certain of the Company’s marketable securities is temporary.
Accounts Receivable	Accounts Receivable Accounts receivable is stated net of the reserves for doubtful accounts of $226,000 as of December 31, 2021 and June 30, 2021, respectively. Our reserves for doubtful accounts are subjective critical estimates that have a direct impact on reported net earnings. These reserves are based upon the evaluation of our accounts receivable aging, specific exposures, sales levels and historical trends.
Inventories	Inventories Inventories are valued at the lower of cost or net realizable value, with cost being determined on the first-in, first-out (FIFO) method. The reported net value of inventory includes finished saleable products, work-in-process and raw materials that will be sold or used in future periods. Inventory costs include raw materials, direct labor and overhead. The Company’s overhead expenses are applied based, in part, upon estimates of the proportion of those expenses that are related to procuring and storing raw materials as compared to the manufacture and assembly of finished products. These proportions, the method of their application, and the resulting overhead included in ending inventory, are based in part on subjective estimates and actual results could differ from those estimates. In addition, the Company records an inventory obsolescence reserve, which represents any excess of the cost of the inventory over its estimated realizable value, based on various product sales projections. This reserve is calculated using an estimated obsolescence percentage applied to the inventory based on age, historical trends, requirements to support forecasted sales, and the ability to find alternate applications of its raw materials and to convert finished product into alternate versions of the same product to better match customer demand. In addition, and as necessary, the Company may establish specific reserves for future known or anticipated events. There is inherent professional judgment and subjectivity made by both production and engineering members of management in determining the estimated obsolescence percentage. The Company also regularly reviews the period over which its inventories will be converted to sales. Any inventories expected to convert to sales beyond 12 months from the balance sheet date are classified as non-current.
Property, Plant, and Equipment	Property, Plant, and Equipment Property, plant, and equipment are carried at cost less accumulated depreciation. Expenditures for maintenance and repairs are charged to expense as incurred; costs of major renewals and improvements are capitalized. At the time property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are eliminated from the asset and accumulated depreciation accounts and the profit or loss on such disposition is reflected in income. Depreciation is recorded over the estimated service lives of the related assets using primarily the straight-line method. Amortization of leasehold improvements is calculated by using the straight-line method over the estimated useful life of the asset or lease term, whichever is shorter.
Long-Lived and Intangible Assets	Long-Lived and Intangible Assets Long-lived assets are amortized over their useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets in question may not be recoverable. Impairment would be recorded in circumstances where undiscounted cash flows expected to be generated by an asset are less than the carrying value of that asset. Intangible assets determined to have indefinite lives were not amortized but were tested for impairment at least annually. The Company’s acquisition of substantially all of the assets and certain liabilities of G. Marks Hardware, Inc. (“Marks”) in August 2008 included intangible assets recorded at fair value on the date of acquisition. The customer relationships are amortized over their estimated useful lives of twenty years. At the acquisition date, the Marks trade name was deemed to have an indefinite life. During the 4th quarter of fiscal 2020, the Company determined that the trade-name was impaired. Accordingly, the Company recorded an impairment charge of $1,852,000 and reclassified the remaining balance of the underlying asset from indefinite-lived to a long-lived asset with a remaining useful life of 20 years as of June 30, 2020. Changes in intangible assets are as follows (in thousands): December 31, 2021 June 30, 2021 Carrying Accumulated Net book Carrying Accumulated Net book value amortization value value amortization value Customer relationships $ 9,800 (9,049) $ 751 $ 9,800 $ (8,955) $ 845 Trade name 4,048 (304) 3,744 4,048 (202) 3,846 $ 13,848 $ (9,353) $ 4,495 $ 13,848 $ (9,157) $ 4,691 Amortization expense for intangible assets subject to amortization was approximately $98,000 and $107,000 for the three months ended December 31, 2021 and 2020, respectively. Amortization expense for intangible assets subject to amortization was approximately $196,000 and $213,000 for the six months ended December 31, 2021 and 2020, respectively. Amortization expense for each of the next five fiscal years is estimated to be as follows: 2022-$390,000; 2023 - $361,000; 2024 - $336,000; 2025 - $315,000; and 2026-$297,000. The weighted average remaining amortization period for intangible assets was 16.5 years and 16.9 years at December 31, 2021 and June 30, 2021, respectively.
Revenue Recognition	Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. For product sales, the Company typically transfers control at a point in time upon shipment or delivery of the product. For monthly communication services the Company satisfies its performance obligation as the services are rendered and therefore recognizes revenue over the monthly period. Typically timing of revenue recognition coincides with the timing of invoicing to the customers, at which time the Company has an unconditional right to consideration. As such, the Company typically records a receivable when revenue is recognized. The contract with the customer states the final terms of the sale, including the description, quantity, and price of each product purchased. Payment for product sales is typically due within 30 and 180 days of the delivery date. Payment for monthly communication services is billed on a monthly basis and is typically due at the beginning of the month of service. The Company provides limited standard warranty for defective products, usually for a period of 24 to 36 months. The Company accepts returns for such defective products as well as for other limited circumstances. The Company also provides rebates to customers for meeting specified purchasing targets and other coupons or credits in limited circumstances. The Company establishes reserves for the estimated returns, rebates and credits and measures such variable consideration based on the expected value method using an analysis of historical data. Changes to the estimated variable consideration in subsequent periods are not material. The Company analyzes sales returns and is able to make reasonable and reliable estimates of product returns based on the Company’s past history. Estimates for sales returns are based on several factors including actual returns and based on expected return data communicated to it by its customers. Accordingly, the Company believes that its historical returns analysis is an accurate basis for its allowance for sales returns. Actual results could differ from those estimates.
Advertising and Promotional Costs	Advertising and Promotional Costs Advertising and promotional costs are included in "Selling, General and Administrative" expenses in the consolidated statements of income and are expensed as incurred. Advertising expense for the three months ended December 31, 2021 and 2020 was $512,000 and $347,000, respectively. Advertising expense for the six months ended December 31, 2021 and 2020 was $1,598,000 and $690,000, respectively
Research and Development Costs	Research and Development Costs Research and development (“R&D”) costs incurred by the Company are charged to expense as incurred and are included in operating expenses in the consolidated statements of income. Company-sponsored R&D expense for the three months ended December 31, 2021 and 2020 was $1,978,000 and $1,884,000, respectively. R&D expense for the six months ended December 31, 2021 and 2020 was $3,909,000 and $3,773,000, respectively.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred income tax expense represents the change during the period in the deferred tax assets and deferred tax liabilities. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company measures and recognizes the tax implications of positions taken or expected to be taken in its tax returns on an ongoing basis. The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.
Net Income per Share	Net Income per Share Basic net income per common share (Basic EPS) is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per common share (Diluted EPS) is computed by dividing net income by the weighted average number of common shares and dilutive common share equivalents and convertible securities then outstanding. The following provides a reconciliation of information used in calculating the per share amounts for the three months ended December 31, 2021 and 2020 (in thousands, except share and per share data): Net Income Weighted Average Shares Net Income per Share 2021 2020 2021 2020 2021 2020 Basic EPS $ 1,037 $ 3,197 36,728 36,695 $ 0.03 $ 0.09 Effect of Dilutive Securities: Stock Options — — 170 110 — — Diluted EPS $ 1,037 $ 3,197 36,898 36,805 $ 0.03 $ 0.09 Options to purchase 80,435 and 64,000 shares of common stock were excluded for the three months ended December 31, 2021 and 2020, respectively, and were not included in the computation of Diluted EPS because their inclusion would be anti-dilutive. These options were still outstanding at the end of the period. The following provides a reconciliation of information used in calculating the per share amounts for the six months ended December 31, 2021 and 2020 (in thousands, except share and per share data): Weighted Average Net Income per Net Income Shares Share 2021 2020 2021 2020 2021 2020 Basic EPS $ 8,789 $ 5,516 36,720 36,695 $ 0.24 $ 0.15 Effect of Dilutive Securities: Stock Options — — 157 99 — — Diluted EPS $ 8,789 $ 5,516 36,877 36,794 $ 0.24 $ 0.15 Options to purchase 40,217 and 72,000 shares of common stock were excluded for the six months ended December 31, 2021 and 2020, respectively, and were not included in the computation of Diluted EPS because their inclusion would be anti-dilutive. These options were still outstanding at the end of the period.
Stock-Based Compensation	Stock-Based Compensation The Company has established four share incentive programs as discussed in Note 9. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the vesting period. Determining the fair value of share-based awards at the grant date requires assumptions and judgments about expected volatility and forfeiture rates, among other factors. Stock-based compensation costs of $1,255,000 and $84,000 were recognized for the three months ended December 31, 2021 and 2020, respectively. Stock-based compensation costs of $1,344,000 and $188,000 were recognized for the six months ended December 31, 2021 and 2020, respectively.
Foreign Currency	Foreign Currency The Company has determined the functional currency of all foreign subsidiaries is the U.S. Dollar. All foreign operations are considered a direct and integral part or extension of the Company’s operations. The day-to-day operations of all foreign subsidiaries are dependent on the economic environment of the U.S. Dollar. Therefore, no realized and unrealized gains and losses associated with foreign currency translation are recorded for the three or six months ended December 31, 2021 or 2020.
Comprehensive Income	Comprehensive Income For the three and six months ended December 31, 2021 and 2020, the Company’s operations did not give rise to material items includable in comprehensive income, which were not already included in net income. Accordingly, the Company’s comprehensive income approximates its net income for all periods presented.
Segment Reporting	Segment Reporting The Company’s reportable operating segments are determined based on the Company’s management approach. The management approach is based on the way that the chief operating decision maker organizes the segments within an enterprise for making operating decisions and assessing performance. The Company’s results of operations are reviewed by the chief operating decision maker on a consolidated basis and the Company operates in only one segment. The Company has presented required geographical data in Note 14.
Shipping and Handling Sales and Costs	Shipping and Handling Sales and Costs The Company records the amount billed to customers for shipping and handling in net sales ($106,000 and $93,000 in the three months ended December 31, 2021 and 2020, respectively and $212,000 and $199,000 in the six months ended December 31, 2021 and 2020, respectively); and classifies the costs associated with these sales in cost of sales ($361,000 and $230,000 in the three months ended December 31, 2021 and 2020, respectively and $694,000 and $451,000 in the six months ended December 31, 2021 and 2020, respectively).
Leases	Leases Effective July 1, 2019, the Company adopted the new lease accounting standard using the modified retrospective transition option of applying the new standard at the adoption date. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to not reassess (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases, and (3) initial direct costs for any existing leases. Adoption of the new standard resulted in the recording of an operating ROU asset and lease liabilities
Recently Adopted Accounting Standards and Recently Issued Accounting Standards	Recently Issued Accounting Standards Reference Rate Reform (ASC Topic 848) In March 2020, the FASB issued authoritative guidance to provide optional relief for companies preparing for the discontinuation of interest rates such as the London Interbank Offered Rate (“LIBOR”), which is expected to be phased out at the end of calendar 2021, and applies to lease contracts, hedging instruments, held-to-maturity debt securities and debt arrangements that have LIBOR as the benchmark rate. In January 2021, the FASB issued authoritative guidance that makes amendments to the new rules on accounting for reference rate reform. The amendments clarify that for all derivative instruments affected by the changes to interest rates used for discounting, margining or contract price alignment, regardless of whether they reference LIBOR or another rate expected to be discontinued as a result of reference rate reform, an entity may apply certain practical expedients in ASC Topic 848. Effective for the Company – This guidance can be applied for a limited time through December 31, 2022. The guidance will no longer be available to apply after December 31, 2022. Impact on consolidated financial statements – The Company is currently assessing the impact of applying this guidance on its existing derivative contracts, leases and other arrangements, as well as when to adopt this guidance.
