Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Feb. 28, 2019
Notes to Financial Statements |
Advertising Expenses | Advertising Expenses - The Company expenses the cost of advertising in the period in which the advertising takes place. Advertising expense for fiscal 2019 and fiscal 2018 was $246,681 and $280,348, respectively.
Allowance for doubtful accounts | Allowance for doubtful accounts - The Company records a bad debt expense/allowance based on management’s estimate of uncollectible accounts. All outstanding accounts receivable accounts are reviewed for collectability on an individual basis. The bad debt expense recorded for fiscal 2019 and fiscal 2018 was approximately $0.
Cash and Cash Equivalents | Cash and Cash Equivalents - Cash and cash equivalents consist of money market mutual funds, short term commercial paper and short-term certificates of deposit with original maturities of 90 days or less.
Concentration of Credit Risk | Concentration of Credit Risk - The Company does not believe that it is subject to any unusual or significant risks, in the normal course of business. The Company had one customer, which accounted for 14% of sales during fiscal 2019. Two customers accounted for 41% of the outstanding accounts receivables at February 28, 2019. The Company had one customer, which accounted for 8% of sales during fiscal 2018. Two customers accounted for 22% of the outstanding accounts receivables at February 28, 2018.
Consolidation | Consolidation - The accompanying consolidated financial statements of the Company include the accounts of the Company and its wholly owned subsidiary, Sono-Tek Industrial Park, LLC (“SIP”). SIP operates as a real estate holding company for the Company’s real estate operations.
Earnings Per Share | Earnings Per Share - Basic earnings per share (“EPS”) is computed by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.
Equipment, Furnishings and Leasehold Improvements | Equipment, Furnishings and Leasehold Improvements – Equipment, furnishings and leasehold improvements are stated at cost. Depreciation of equipment and furnishings is computed by use of the straight-line method based on the estimated useful lives of the assets, which range from three to five years.
Fair Value of Financial Instruments | Fair Value of Financial Instruments - The Company follows the guidance in the “Fair Value Measurements and Disclosure Topic” of the Accounting Standards Codification for assets and liabilities measured at fair value on a recurring basis. This guidance establishes a common definition for fair value to be applied to existing generally accepted accounting principles that require the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. The guidance defines fair value as the price 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. Additionally, the guidance requires the use of valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized below: Level 1: Quoted prices in active markets. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions. The fair values of financial assets of the Company were determined using the following categories at February 28, 2019 and 2018, respectively:
|  | Quoted Prices in Active Markets |
|  | (Level 1) |
|  | February 28, |
|  | 2019 |  |  | 2018 |
Marketable Securities |  | $ | 2,365,706 |  |  | $ | 4,405,900 |
Marketable Securities include mutual funds, certificates of deposit and US Treasury securities, totaling $2,365,706 and $4,405,900 that are considered to be highly liquid and easily tradeable as of February 28, 2019 and 2018, respectively. These securities are valued using inputs observable in active markets for identical securities and are therefore classified as Level 1 within the Company’s fair value hierarchy. The Company’s marketable securities are considered to be available-for-sale investments as defined under ASC 320 “Investments – Debt and Equity Securities.” As of February 28, 2019, certain of the Company’s marketable securities were in an unrealized gain position. Unrealized gains and losses are principally due to changes in the fair value of the Company’s investments held as available-for-sale. Because the Company has the ability and intent to hold the securities for the foreseeable future as classified as available-for-sale, the Company does not deem these unrealized gains or losses to be other than temporary. Net unrealized gains at February 28, 2019 are $1,422.
Income Taxes | Income Taxes - The Company accounts for income taxes under the asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences of "temporary differences" by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. If it is more likely than not that some portion or all of a deferred tax asset will not be realized, a valuation allowance is recognized.
Intangible Assets | Intangible Assets -Include costs of patent applications which are deferred and charged to operations over seventeen years for domestic patents and twelve years for foreign patents. The accumulated amortization of patents is $160,433 and $149,654 at February 28, 2019 and 2018, respectively. Annual amortization expense of such intangible assets is expected to be approximately $11,000 per year for the next five years.
Inventories | Inventories - Inventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out (FIFO) method for raw materials, subassemblies and work-in-progress and the specific identification method for finished goods.
Land and Buildings | Land and Buildings – Land and buildings are stated at cost. Buildings are being depreciated by use of the straight-line method based on an estimated useful life of forty years.
Long-Lived Assets | Long-Lived Assets - The Company periodically evaluates the carrying value of long-lived assets, including intangible assets, when events and circumstances warrant such a review. The carrying value of a long-lived asset is considered impaired when the anticipated undiscounted cash flow from such asset is separately identifiable and is less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset. Fair market value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved.
Management Estimates | Management Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Marketable Securities | Marketable Securities - The Company adopted ASU 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset, and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The Company has evaluated the potential impact this standard may have on the consolidated financial statements and the fair value allowance of the securities from the prior year has been reclassified to Retained Earnings from Other Accumulated Comprehensive Income. The unrealized loss on the marketable securities during the year ended February 28, 2019 has been disclosed as a separate line item on the Income Statement.
New Accounting Pronouncements | New Accounting Pronouncements - In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset, and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. ASU 2016-01 is effective for all entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company has evaluated the potential impact this standard may have on the consolidated financial statements, the fair value of the securities from the prior year has been reclassified to Retained Earnings from Other Accumulated Comprehensive Income. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either operating or financing, with such classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for fiscal years and interim periods within those years beginning after December 15, 2018, and early adoption is permitted. The adoption of ASU 2016-02 will have no material impact on the Company’s financial statements. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220), “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. ASU 2018-02 was issued to allow the reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effect resulting from the Tax Cuts and Jobs Act enacted on December 22, 2017. The Tax Cuts and Jobs Act, among other things, reduced the corporate tax rate from 35% to 21%, which required the re-evaluation of any deferred tax assets and liabilities at the lowered tax rate which potentially could leave a disproportionate tax effect in accumulated other comprehensive income. ASU 2018-02 allows for the election to reclassify these stranded tax effects to retained earnings. ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period for public business entities for reporting periods for which financials statements have not yet been issued. The adoption of ASU 2018-02 will have no material impact on the Company’s financial statements. Other than ASU No. ASU 2016-01, ASU 2016-02 and ASU 2018-02 discussed above, all new accounting pronouncements issued but not yet effective have been deemed to be not applicable to the Company. Hence, the adoption of these new accounting pronouncements, once effective, is not expected to have an impact on the Company.
Product Warranty | Product Warranty - Expected future product warranty expense is recorded when the product is sold.
Reclassifications | Reclassifications – Where appropriate, prior year’s financial statements reflect reclassifications to conform to the current year’s presentation.
Research and Product Development Expenses | Research and Product Development Expenses - Research and product development expenses represent engineering and other expenditures incurred for developing new products, for refining the Company's existing products and for developing systems to meet unique customer specifications for potential orders or for new industry applications and are expensed as incurred.
Shipping and Handling Costs | Shipping and Handling Costs – Shipping and handling costs are included in cost of sales in the accompanying consolidated statements of operations.
