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. and Subsidiaries (the "Company") is a diversified manufacturer of security products, encompassing access control systems, door-locking products, intrusion and fire alarm systems and video surveillance products for commercial and residential use. The Company also provides wireless communication service for intrusion and fire alarm systems. 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. The Company’s fiscal year begins on July 1 and ends on June 30. Historically, the end users of the Company’s products want to install its products prior to the summer; therefore sales of its 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 is affected by the housing and construction markets. Significant Accounting Policies : Principles of Consolidation The consolidated financial statements include the accounts of Napco Security Technologies, Inc. and all of its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation. 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, 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 June 30, 2019 and 2018 due to their short-term maturities. Cash and Cash Equivalents Cash and cash equivalents include approximately $460,000 of short-term time deposits at June 30, 2019 and 2018. 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 June 30, 2019 and 2018. The Company has not historically experienced any credit losses with balances in excess of FDIC limits. Accounts Receivable Accounts receivable is stated net of the reserves for doubtful accounts of $88,000 and $195,000 as of June 30, 2019 and 2018, 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. Intangible Assets Intangible assets determined to have indefinite lives are not amortized but are tested for impairment at least annually. Intangible assets with definite lives are amortized over their useful lives. Infinite-lived intangible assets are reviewed for impairment at least annually at the Company’s fiscal year end of June 30 or more often whenever there is an indication that the carrying amount may not be recovered. 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. The Marks trade name was deemed to have an indefinite life. Changes in intangible assets are as follows (in thousands): June 30, 2019 June 30, 2018 Accumulated Net book Accumulated Net book Cost amortization value Cost amortization value Customer relationships $ 9,800 $ (8,468) $ 1,332 $ 9,800 $ (8,155) $ 1,645 Trade name 5,900 — 5,900 5,900 — 5,900 $ 15,700 $ (8,468) $ 7,232 $ 15,700 $ (8,155) $ 7,545 Amortization expense for intangible assets subject to amortization was approximately $313,000 and $371,000 for the fiscal years ended June 30, 2019 and 2018, respectively. Amortization expense for each of the next five fiscal years is estimated to be as follows: 2020 - $264,000; 2021 - $223,000; 2022 - $188,000; 2023 - $159,000; and 2024 - $134,000. The weighted average remaining amortization period for intangible assets was 9.1 years and 10.1 years at June 30, 2019 and 2018, respectively. Long-Lived Assets Long-lived assets 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. Revenue Recognition The Company recognizes revenue in accordance with Accounting Standards Codification ("ASC"), Topic 606, Revenue from Contracts with Customers , which the Company adopted effective July 1, 2018. Accordingly, the Company recognizes revenue when its customers obtain control of its products or services, in an amount that reflects the consideration that the Company expects to receive in exchange for those goods and services. See Note 2 - Revenue Recognition for additional accounting policies and transition disclosures. 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 fiscal years ended June 30, 2019 and 2018 was $2,047,000 and $2,011,000, respectively. Research and Development Costs Research and development 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 research and development expense for the fiscal years ended June 30, 2019 and 2018 was $7,212,000 and $6,630,000, 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. 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 fiscal years ended June 30 (in thousands, except per share data): Weighted Average Net Income per Net Income Shares Share 2019 2018 2019 2018 2019 2018 Basic EPS $ 12,223 $ 7,649 18,574 18,788 $ 0.66 $ 0.41 Effect of Dilutive Securities: Stock Options — — 50 37 — — Diluted EPS $ 12,223 $ 7,649 18,624 18,825 $ 0.66 $ 0.41 Options to purchase 2,957 and 217 shares of common stock were excluded for the fiscal years ended June 30, 2019 and 2018, 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 respective periods. Stock-Based Compensation The Company has established three share incentive programs as discussed in Note 8. 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 $160,000 and $146,000 were recognized for the fiscal years ended June 30, 2019 and 2018, 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 is recorded for the fiscal years ended June 30, 2019 or 2018. Comprehensive Income For the fiscal years ended June 30, 2019 and 2018, 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 12. Shipping and Handling Revenues and Costs The Company records the amount billed to customers for shipping and handling in net sales ($430,000 and $476,000 in the fiscal years ended June 30, 2019 and 2018, respectively) and classifies the costs associated with these revenues in cost of sales ($1,115,000 and $988,000 in the fiscal years ended June 30, 2019 and 2018, respectively). Recently Issued and Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09), which amended the accounting standards for revenue recognition. This standard superseded all prior revenue recognition standards and requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted this ASU effective July 1, 2018. See Note 2, Revenue Recognition for additional accounting policy and transition disclosures. In February 2016, the FASB issued authoritative guidance that requires lessees to account for most leases on their balance sheets with the liability being equal to the present value of the lease payments. The right-of-use asset will be based on the lease liability adjusted for certain costs such as direct costs. Lease expense will be recognized similar to current accounting guidance with operating leases resulting in a straight-line expense and financing leases resulting in a front-loaded expense similar to the current accounting for capital leases. This guidance becomes effective for the Company’s fiscal 2020 first quarter, with early adoption permitted. This guidance must be adopted using a modified retrospective transition approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and provides for certain practical expedients. We anticipate the adoption of this standard will result in an increase in our right of use assets and lease liabilities recorded on our consolidated balance sheets on July 1, 2019. The Company does not believe the adoption of this guidance will have a material impact on its consolidated results of operations or cash flows.

Revenue Recognition and Contracts with Customers
Revenue Recognition and Contracts with Customers	NOTE 2 – Revenue Recognition and Contracts with Customers Adoption On July 1, 2018, the Company adopted new guidance on revenue from contracts with customers using the modified retrospective method applied to contracts that were not completed as of July 1, 2018. Results for reporting periods beginning after July 1, 2018 are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with previous guidance. The Company recorded a net decrease to opening retained earnings of approximately $719,000 (net of tax benefit of $191,000) as of July 1, 2018, for the cumulative impact of adopting the new guidance. The impact primarily related to the change in the recognition and measurement of certain types of variable consideration, which resulted in the increase in sales allowance reserves (i.e. refund liabilities) by a net of $1,627,000 and increased other assets (i.e. return related assets) by approximately $716,000. As of June 30, 2019, the Company included return-related assets of approximately $820,000 in other current assets. Also, due to the adoption of the new standard, the Company classified certain reserves in respect of refund liabilities that were previously presented as a reduction from receivables, to current liabilities amounting to approximately $3,524,000 as of June 30, 2019. Further, amounts related to promotion payments to customers are now classified as a reduction of sales. The impact of applying this ASU for the fiscal year ended June 30, 2019 resulted in an immaterial change in product sales. Net Sales The Company is engaged in one major line of business: the development, manufacture, and distribution of security products, encompassing access control systems, door security products, intrusion and fire alarm systems, alarm communication services, and video surveillance products for commercial and residential use. The Company also provides wireless communication service for intrusion and fire alarm systems on a monthly basis. 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. Sales to unaffiliated customers are primarily shipped from the United States. The Company has customers worldwide with major concentrations in North America. 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. As a percentage of gross sales, sales returns, rebates and allowances were 8% and 7% for the fiscal years ended June 30, 2019 and 2018, respectively. In accordance with ASC 606-10-50, the Company disaggregates revenue from contracts with customers into major product lines. The Company determines that disaggregating revenue into these categories achieves the disclosure objective to depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. As noted in the accounting policy footnote, the Company’s business consists of one operating segment. Following is the disaggregation of revenues based on major product lines (in thousands): Fiscal year ended June 30, 2019 2018 Major Product Lines: Intrusion and access alarm products $ 31,557 $ 28,610 Door locking devices 53,948 51,134 Services 17,427 12,002 Total Revenues $ 102,932 $ 91,746

Business and Credit Concentrations
Business and Credit Concentrations	NOTE 3 - Business and Credit Concentrations An entity is more vulnerable to concentrations of credit risk if it is exposed to risk of loss greater than it would have had if it mitigated its risk through diversification of customers. Such risks of loss manifest themselves differently, depending on the nature of the concentration, and vary in significance. The Company had one customer with an accounts receivable balance that comprised 19% and 22% of the Company’s accounts receivable at June 30, 2019 and 2018, respectively. Sales to this customer comprised 10% of net sales in each of the fiscal years ended June 30, 2019 and 2018. The Company had another customer with an accounts receivable balance that comprised 11% of the Company’s accounts receivable at June 30, 2019 and June 30, 2018. Sales to this customer did not exceed 10% of net sales in either of the fiscal years ended June 30, 2019 and 2018.

Fiscal 2016 and forward years are still open for examination. In addition, the Company has a wholly-owned subsidiary which operates in a Free Zone in the Dominican Republic (“DR”) and is exempt from DR income tax. The Company was audited by the Internal Revenue Service ("IRS") for the fiscal year 2016. In July 2019, the Company received Form 4549-A, Income Tax Examination Changes from the IRS proposing an adjustment to income for the fiscal 2016 tax year regarding deemed dividends based on its interpretation under Internal Revenue Code ("IRC") Section 956 arising from the intercompany balances on the books of the Company. The incremental tax liability associated with the income adjustment proposed by the IRS would be approximately $1.8 million, excluding any interest and penalties. In August 2019 the Company filed a formal protest with the IRS requesting an opportunity to appeal the examination findings to the Appeals Office. The Company believes that the position of the IRS with regard to this matter is inconsistent with the provisions of IRC Section 956 and management believes that the Company will prevail, and that the tax originally paid in fiscal 2016 is correct, as such no additional reserve for this tax uncertainty has been recognized. However, there can be no assurance that this matter will ultimately be resolved in the Company's favor. 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 tax rates in foreign jurisdictions, state and local income taxes, tax benefit of R&D credits, certain nondeductible expenses , release of uncertain tax positions for R &D tax credits and global intangible low-taxed income ("GILTI"). On December 22, 2017, the U.S. government passed the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act is comprehensive tax legislation effective January 1, 2018 that implements complex changes to the U.S. tax code including, but not limited to, the reduction of the corporate tax rate from 35% to 21% and includes provisions to tax GILTI. We are subject to the GILTI provisions effective for fiscal year ended June 30, 2019. The Tax Act also imposed a one-time transition tax on its unremitted foreign earnings. ASC 740 requires filers to record the effects of tax law changes in the period enacted. However, the SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”), that permits filers to record provisional amounts during a measurement period ending no later than one year from the date of the Act’s enactment. As of March 31, 2019, the Company finalized its accounting for the income tax effects of the Tax Act and no additional expense was recorded since the final transition tax expense was equal to the $381,000 provisional expense reported in the fiscal year ended June 30, 2018. The net section 965 tax liability was $442,000, which is payable over 8 years. During the year ending June 30, 2019 the Company decreased its reserve for uncertain income tax positions by $96,000. 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 June 30, 2019, the Company had accrued interest totaling $0 and $125,000 of unrecognized net tax benefits that, if recognized, would favorably affect the Company’s effective income tax rate in any future period. The Company does not expect that its unrecognized tax benefits will significantly change within the next twelve months. The Company claims R&D tax credits on eligible research and development expenditures. The R&D tax credits are recognized as a reduction to income tax expense. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): Tax Interest Total Balance of gross unrecognized tax benefits as of July 1, 2017 $ 183 $ — $ 183 Increases to unrecognized tax benefits resulting from the generation of additional R&D credits 38 — 38 Balance of gross unrecognized tax benefits as of June 30, 2018 $ 221 $ — $ 221 Decrease to unrecognized tax benefits resulting from the release of R&D credits due to the IRS audit (151) — (151) Increases to unrecognized tax benefits resulting from the generation of additional R&D credits 55 — 55 Balance of gross unrecognized tax benefits as of June 30, 2019 $ 125 $ — $ 125 The Company plans to permanently reinvest a substantial portion of its foreign earnings and as such has not provided withholding tax on the permanently reinvested earnings. The Company has accrued $408,000 for withholding taxes on undistributed earnings that are not permanently reinvested. As of June 30, 2019 the Company had approximately $31.3 million of undistributed earnings of foreign subsidiaries.

Stock Options
Stock Options	NOTE 8 - 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 fiscal years ended June 30, 2019 and 2018, the Company recorded non-cash compensation expense of $160,000 ($0.01 per basic and diluted share) and $146,000 ($0.01 per basic and diluted share), respectively, relating to stock-based compensation 2012 Employee Stock Option Plan In December 2012, the stockholders approved the 2012 Employee Stock Option Plan (the 2012 Employee Plan). The 2012 Employee Plan authorizes the granting of awards, the exercise of which would allow up to an aggregate of 950,000 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), 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 June 30, 2019, 72,500 stock options were outstanding, 33,800 stock options were exercisable and 792,900 stock options were available for grant under this plan. The fair value of each option granted during fiscal 2019 and 2018 was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: 2019 2018 Risk-free interest rates 2.5% - 3.1 % 2.4 % Expected lives 10 years 10 years Expected volatility 48% - 52 % 52 % Expected dividend yields 0 % 0 % The Company uses a weighted-average expected stock-price volatility assumption that is a combination of both current and historical implied volatilities of the underlying stock. The implied volatilities were obtained from publicly available data sources. For the weighted-average expected option life assumption, the Company considers the exercise behavior of past grants. The average risk-free interest rate is based on the U.S. Treasury Bond rate for the expected term of the options and the average dividend yield is based on historical experience.

Nature of Business and Summary of Significant Accounting Policies
Nature of Business	Nature of Business : Napco Security Technologies, Inc. and Subsidiaries (the "Company") is a diversified manufacturer of security products, encompassing access control systems, door-locking products, intrusion and fire alarm systems and video surveillance products for commercial and residential use. The Company also provides wireless communication service for intrusion and fire alarm systems. 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. The Company’s fiscal year begins on July 1 and ends on June 30. Historically, the end users of the Company’s products want to install its products prior to the summer; therefore sales of its 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 is affected by the housing and construction markets.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Napco Security Technologies, Inc. and all of its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation.
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, 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 June 30, 2019 and 2018 due to their short-term maturities.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include approximately $460,000 of short-term time deposits at June 30, 2019 and 2018. 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 June 30, 2019 and 2018. The Company has not historically experienced any credit losses with balances in excess of FDIC limits.
Accounts Receivable	Accounts Receivable Accounts receivable is stated net of the reserves for doubtful accounts of $88,000 and $195,000 as of June 30, 2019 and 2018, 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.
Intangible Assets	Intangible Assets Intangible assets determined to have indefinite lives are not amortized but are tested for impairment at least annually. Intangible assets with definite lives are amortized over their useful lives. Infinite-lived intangible assets are reviewed for impairment at least annually at the Company’s fiscal year end of June 30 or more often whenever there is an indication that the carrying amount may not be recovered. 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. The Marks trade name was deemed to have an indefinite life. Changes in intangible assets are as follows (in thousands): June 30, 2019 June 30, 2018 Accumulated Net book Accumulated Net book Cost amortization value Cost amortization value Customer relationships $ 9,800 $ (8,468) $ 1,332 $ 9,800 $ (8,155) $ 1,645 Trade name 5,900 — 5,900 5,900 — 5,900 $ 15,700 $ (8,468) $ 7,232 $ 15,700 $ (8,155) $ 7,545 Amortization expense for intangible assets subject to amortization was approximately $313,000 and $371,000 for the fiscal years ended June 30, 2019 and 2018, respectively. Amortization expense for each of the next five fiscal years is estimated to be as follows: 2020 - $264,000; 2021 - $223,000; 2022 - $188,000; 2023 - $159,000; and 2024 - $134,000. The weighted average remaining amortization period for intangible assets was 9.1 years and 10.1 years at June 30, 2019 and 2018, respectively.
Long-Lived Assets	Long-Lived Assets Long-lived assets 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.
Revenue Recognition	Revenue Recognition The Company recognizes revenue in accordance with Accounting Standards Codification ("ASC"), Topic 606, Revenue from Contracts with Customers , which the Company adopted effective July 1, 2018. Accordingly, the Company recognizes revenue when its customers obtain control of its products or services, in an amount that reflects the consideration that the Company expects to receive in exchange for those goods and services. See Note 2 - Revenue Recognition for additional accounting policies and transition disclosures.
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 fiscal years ended June 30, 2019 and 2018 was $2,047,000 and $2,011,000, respectively.
Research and Development Costs	Research and Development Costs Research and development 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 research and development expense for the fiscal years ended June 30, 2019 and 2018 was $7,212,000 and $6,630,000, 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.
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 fiscal years ended June 30 (in thousands, except per share data): Weighted Average Net Income per Net Income Shares Share 2019 2018 2019 2018 2019 2018 Basic EPS $ 12,223 $ 7,649 18,574 18,788 $ 0.66 $ 0.41 Effect of Dilutive Securities: Stock Options — — 50 37 — — Diluted EPS $ 12,223 $ 7,649 18,624 18,825 $ 0.66 $ 0.41 Options to purchase 2,957 and 217 shares of common stock were excluded for the fiscal years ended June 30, 2019 and 2018, 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 respective periods.
Stock-Based Compensation	Stock-Based Compensation The Company has established three share incentive programs as discussed in Note 8. 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 $160,000 and $146,000 were recognized for the fiscal years ended June 30, 2019 and 2018, 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 is recorded for the fiscal years ended June 30, 2019 or 2018.
Comprehensive Income	Comprehensive Income For the fiscal years ended June 30, 2019 and 2018, 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 12.
Shipping and Handling Revenues and Costs	Shipping and Handling Revenues and Costs The Company records the amount billed to customers for shipping and handling in net sales ($430,000 and $476,000 in the fiscal years ended June 30, 2019 and 2018, respectively) and classifies the costs associated with these revenues in cost of sales ($1,115,000 and $988,000 in the fiscal years ended June 30, 2019 and 2018, respectively).
Recently Issued Accounting Standards	Recently Issued and Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09), which amended the accounting standards for revenue recognition. This standard superseded all prior revenue recognition standards and requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted this ASU effective July 1, 2018. See Note 2, Revenue Recognition for additional accounting policy and transition disclosures. In February 2016, the FASB issued authoritative guidance that requires lessees to account for most leases on their balance sheets with the liability being equal to the present value of the lease payments. The right-of-use asset will be based on the lease liability adjusted for certain costs such as direct costs. Lease expense will be recognized similar to current accounting guidance with operating leases resulting in a straight-line expense and financing leases resulting in a front-loaded expense similar to the current accounting for capital leases. This guidance becomes effective for the Company’s fiscal 2020 first quarter, with early adoption permitted. This guidance must be adopted using a modified retrospective transition approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and provides for certain practical expedients. We anticipate the adoption of this standard will result in an increase in our right of use assets and lease liabilities recorded on our consolidated balance sheets on July 1, 2019. The Company does not believe the adoption of this guidance will have a material impact on its consolidated results of operations or cash flows.
