Notes to Financial Statements
Significant Accounting Policies [Text Block]	NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements have been prepared by ADM pursuant to accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) including Form 10-Q and Regulation S-X. The information furnished herein reflects all adjustments (consisting of normal recurring accruals and adjustments) which are, in the opinion of management, necessary to fairly present the condensed financial position and operating results for the respective periods. Certain information and footnote disclosures normally present in annual financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and explanatory notes for the year ended March 31, 2023 as disclosed in our annual report on Form 10-K for that year. Unaudited interim results are not necessarily indicative of the results for the full fiscal year ending March 31, 2023. The consolidated balance sheet as of March 31, 2022 was derived from the audited consolidated financial statements as of and for the year then ended. PRINCIPLES OF CONSOLIDATION The condensed consolidated financial statements include the accounts of ADM Tronics Unlimited, Inc. and its wholly owned subsidiary, Sonotron (the “Company”). All significant intercompany balances and transactions have been eliminated in consolidation. USE OF ESTIMATES These unaudited condensed consolidated financial statements have been prepared in accordance with GAAP and, accordingly, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. Significant estimates made by management include expected economic life and value of our deferred tax assets and related valuation allowance, write down of inventory, impairment of long-lived assets, allowance for doubtful accounts, and warranty reserves. Actual results could differ from those estimates. FAIR VALUE OF FINANCIAL INSTRUMENTS For certain of our financial instruments, including accounts receivable, accounts payable, and accrued expenses, the carrying amounts approximate the fair value due to their relatively short maturities. CASH AND CASH EQUIVALENTS Cash equivalents are comprised of highly liquid investments with original maturities of three months or less when purchased. We maintain our cash in bank deposit accounts, which at times, may exceed federally insured limits. We have not experienced any losses to date as a result of this policy. Cash and cash equivalents held in these accounts are currently insured by the Federal Deposit Insurance Corporation (“FDIC”) up to a maximum of $250,000. At June 30, 2023 and March 31, 2023, approximately $595,000 and $638,000, respectively, exceeded the FDIC limit. ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS Accounts receivable are stated at the amount management expects to collect from outstanding balances. The carrying amounts of accounts receivable is reduced by a valuation allowance that reflects management's best estimate of the amounts that will not be collected. Management individually reviews all accounts receivable balances that exceed the due date and estimates the portion, if any, of the balance that will be collected. Management provides for probable uncollectible amounts through a charge to expenses and a credit to a valuation allowance, based on its assessment of the current status of individual accounts. Balances that are still outstanding after management has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable. REVENUE RECOGNITION ELECTRONICS: We recognize revenue from the sale of our electronic products when they are shipped to the purchaser. We offer a limited 90-day warranty on our electronics products and contract manufacturing, and a limited 5-year warranty on our electronic controllers for spas and hot tubs. Historically, the amount of warranty expense included in sales of our electronic products have been de minimis. We have no other post shipment obligations. For contract manufacturing, revenues are recognized after shipments of the completed products. Amounts received from customers in advance of our satisfaction of applicable performance obligations are recorded as customer deposits. Such amounts are recognized as revenues when the related performance obligations are satisfied. Customer deposits of approximately $27,000 and $39,000 were recognized as revenues during the three months ended June 30, 2023 and 2022, respectively. CHEMICAL PRODUCTS: Revenues are recognized when products are shipped to end users. Shipments to distributors are recognized as revenue when no right of return exists. ENGINEERING SERVICES: We provide certain engineering services, including research, development, quality control, and quality assurance services along with regulatory compliance services. We recognize revenue from engineering services over time as the applicable performance obligations are satisfied. All revenue is recognized net of discounts. INVENTORIES Inventories are stated at the lower of cost (first-in, first-out method) and net realizable value. Inventories that are expected to be sold within one operating cycle (1 year) are classified as a current asset. Inventories that are not expected to be sold within 1 year, based on historical trends, are classified as Inventories - long term portion. Obsolete inventory is written off based on prior and expected future usage. Long-Term Inventory: Due to recent shortages of materials relating to supply chain and COVID issues, when an item the Company believes will be used in the future, even beyond the current fiscal year, becomes available, it will purchase as many items as management deems necessary to fulfill future orders. PROPERTY AND EQUIPMENT We record our property and equipment at historical cost. We expense maintenance and repairs as incurred. Depreciation is provided for by the straight-line method over five to seven years, the estimated useful lives of the property and equipment. As of June 30, 2023, all fixed assets were fully depreciated. ADVERTISING COSTS Advertising costs are expensed as incurred and amounted to $6,184 and $8,796 for the three months ended June 30, 2023 and June 30, 2022, respectively. NET LOSS PER SHARE We compute basic earnings per share by dividing net income/loss by the weighted average number of common shares outstanding. Diluted earnings per share is computed similar to basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential shares had been issued and if the additional shares were dilutive. Common equivalent shares are excluded from the computation of net earnings per share if their effect is anti-dilutive. There were no anti-dilutive instruments in force during the periods ended June 30, 2023 and 2022, respectively. Per share basic and diluted (loss) amounted to $(0.00) and $(0.00) for the three months ended June 30, 2023 and 2022, respectively. RECLASSIFICATION Certain amounts in the prior periods presented have been reclassified to conform to the current period financial statement presentation. These reclassifications have no effect on previously reported net loss. NEW ACCOUNTING STANDARDS In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The FASB subsequently issued amendments to ASU 2016-13, which have the same effective date and transition date of April 1, 2023. These standards replace the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measure at amortized cost to be presented at the net amount expected to be collected. The Company determined that this change does not have a material impact to the financial statements or financial statement disclosures.
