Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Consolidation Policy The consolidated financial statements include the accounts and transactions of SigmaTron International, Inc. (“SigmaTron”), its wholly-owned subsidiaries, Standard Components de Mexico, S.A., AbleMex S.A. de C.V., Digital Appliance Controls de Mexico, S.A. de C.V., Spitfire Controls (Vietnam) Co. Ltd., Spitfire Controls (Cayman) Co. Ltd. and SigmaTron International Trading Co., wholly-owned foreign enterprises Suzhou SigmaTron Electronics Co. Ltd., and SigmaTron Electronic Technology Co., Ltd. (collectively, “SigmaTron China”), and its international procurement office, SigmaTron Taiwan. The functional currency of the Mexican, Vietnamese and Chinese subsidiaries and procurement branch is the U.S. Dollar. Intercompany transactions are eliminated in the consolidated financial statements. The impact of currency fluctuations for the fiscal year ended April 30, 2021, resulted in net foreign currency transaction losses of $ 285,389 compared to net foreign currency losses of $ 285,654 in the prior year. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made in preparing the consolidated financial statements include depreciation and amortization periods, the allowance for doubtful accounts, excess and obsolete reserves for inventory, deferred income, deferred taxes, uncertain tax positions, valuation allowance for deferred taxes and valuation of long-lived assets. Actual results could materially differ from these estimates. Cash and Cash Equivalents Cash and cash equivalents include cash and all highly liquid short-term investments with original maturities within three months of the purchase date. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Accounts Receivable The majority of the Company’s accounts receivable are due from companies in the industrial electronics, consumer electronics and medical/life sciences industries. Credit is extended based on evaluation of a customer’s financial condition, and, generally, collateral is not required. Accounts receivable are due in accordance with agreed upon terms, and are stated at amounts due from customers net of an allowance for doubtful accounts. Accounts outstanding longer than the contractual payments terms are considered past due. The Company writes off accounts receivable when they are determined to be uncollectible. The Company has arrangements with various financial institutions to sell certain eligible accounts receivable balances from specific customers without recourse. The accounts receivable balances sold are at the election of the Company. The Company incurred fees for such sales, which are reflected as selling and administrative expenses on the Company’s income statement and were not material for the fiscal years ended April 30, 2021 and 2020. The accounts receivable balances are derecognized at the time of sale, as the Company does not have continuing involvement after the point of sale. During the years ended April 30, 2021 and April 30, 2020, the Company sold without recourse trade receivables of approximately $ 78,000,000 and $ 85,000,000 , respectively. Cash proceeds from these agreements are reflected as operating activities included in the change in accounts receivable in the Company's consolidated statements of cash flows. Allowance for Doubtful Accounts The Company’s allowance for doubtful accounts relates to receivables not expected to be collected from its customers. This allowance is based on management’s assessment of specific customer balances, considering the age of receivables and financial stability of the customer and a five year average of prior uncollectible amounts. If there is an adverse change in the financial condition of the Company’s customers, or if actual defaults are higher than provided for, an addition to the allowance may be necessary. Inventories Inventories are valued at cost. Cost is determined by an average cost method and the Company allocates labor and overhead to work-in-process and finished goods. In the event of an inventory write-down, the Company records expense to state the inventory at lower of cost or net realizable value. The Company establishes inventory reserves for shrinkage and excess and obsolete inventory. The Company records provisions for inventory shrinkage based on historical experience to account for unmeasured usage or loss. Of the Company’s raw materials inventory, a substantial portion has been purchased to fulfill committed future orders or for which the Company is contractually entitled to recover its costs from its customers. For the remaining raw materials inventory, a provision for excess and obsolete inventories is recorded for the difference between the cost of inventory and its estimated realizable value based on assumptions about future product demand and market conditions. Upon a subsequent sale or disposal of the impaired inventory, the corresponding reserve is relieved to ensure the cost basis of the inventory reflects any reductions. Actual results differing from these estimates could significantly affect the Company’s inventories and cost of products sold as the inventory is sold or otherwise relieved. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Property, Machinery and Equipment Property, machinery and equipment are valued at cost. The Company provides for depreciation and amortization using the straight-line method over the estimated useful life of the assets: Buildings 20 years Machinery and equipment 5 - 12 years Office equipment and software 3 - 5 years Tools and dies 12 months Leasehold improvements lesser of lease term or useful life Expenses for repairs and maintenance are charged to selling and administrative expenses as incurred. Deferred Financing Costs Deferred financing costs consist of costs incurred to obtain the Company’s long-term debt and are amortized using the straight line method over the term of the related debt. Deferred financing fees of $ 353,438 and $ 279,740 net of accumulated amortization of $ 18,347 and $ 277,518 , respectively, as of April 30, 2021 and 2020, respectively, are deducted from long term debt on the Company’s consolidated balance sheet. COVID-19 and CARES Act A pandemic of respiratory diseases, including variants (commonly known as "COVID-19") began to spread globally, including to the United States, in early 2020. The full impact of the COVID-19 outbreak is inherently uncertain at the time of this report. The COVID-19 outbreak has resulted in travel restrictions and in some cases, prohibitions of non-essential activities, disruption and shutdown of certain businesses and greater uncertainty in global financial markets. The full extent to which COVID-19 impacts the Company’s business, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of the outbreak within the U.S., China, Mexico, Vietnam and Taiwan, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. Even after COVID-19 has subsided, the Company may continue to experience materially adverse impacts to its business as a result of its global economic impact, including any recession that has occurred or may occur in the future. There are no comparable recent events which may provide guidance as to the effect of the spread of COVID-19, and, as a result, the ultimate impact of COVID-19, or a similar health epidemic or pandemic, is highly uncertain and subject to change. The Company has adopted several measures in response to the COVID-19 outbreak. To date, the Company has been able to continue to meet the needs of its customers. Although the Company cannot estimate the length or gravity of the impact of the COVID-19 outbreak at this time, if the pandemic continues, it will have a material adverse effect on the Company’s results of future operations, financial position, and liquidity in fiscal year 2022. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued COVID-19 and CARES Act - Continued As further described in Note G, the Company has applied for, and has received, funds under the Paycheck Protection Program (“PPP Loan”) in the amount of $ 6,282,973 . The application for these funds required the Company to, in good faith, certify that the current economic uncertainty made the loan request necessary to support the ongoing operations of the Company. This certification further required the Company to take into account its then current business activity and its ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business. The receipt of these funds, and the forgiveness of the loan attendant to these funds, is dependent on the Company having initially qualified for the loan and qualifying for the forgiveness of such loan based on its adherence to the forgiveness criteria. Due to the size of the PPP Loan, it is subject to review by the U.S. Small Business Administration (“SBA”), which introduces a layer of uncertainty. If, despite the Company’s actions and certification that it satisfied all eligibility requirements for the PPP Loan, it is later determined that it violated applicable laws or was otherwise ineligible to receive the PPP Loan, the Company may be required to repay the PPP Loan in its entirety in a lump sum or be subject to additional penalties and interest, which could also result in adverse publicity and damage to the Company’s reputation. If these events were to transpire, they could have a material adverse effect on the Company’s business, results of operations and financial condition. The Company submitted its loan forgiveness application on March 26, 2021. The Company was notified of the forgiveness of the PPP Loan by the SBA on July 9, 2021 and it covers all principal and accrued interest. The accounting for the forgiveness will be reflected in the Company’s first quarter financial statements for fiscal year 2022. Income Taxes The Company’s income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated future taxes to be paid. The Company is subject to income taxes in both the U.S. and several foreign jurisdictions. Significant judgments and estimates by management are required in determining the consolidated income tax expense assessment. Deferred income tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities, and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. In evaluating the Company’s ability to recover its deferred tax assets within the jurisdiction from which they arise, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In projecting future taxable income, the Company begins with historical results and changes in accounting policies, and incorporates assumptions including the amount of future state, federal and foreign pre-tax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment and estimates by management about the forecasts of future taxable income and are consistent with the plans and estimates the Company uses to manage the underlying businesses. In evaluating the objective evidence that historical results provide, the Company considers three years of cumulative operating income and/or loss. Valuation allowances are established when necessary to reduce deferred income tax assets to an amount more likely than not to be realized. A tax benefit from an uncertain tax position may only be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Income Taxes - Continued The calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across its global operations. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Except as noted below, management is not aware of any such changes that would have a material effect on the Company’s results of operations, cash flows or financial position. The Company adjusts its tax liabilities when its judgment changes as a result of the evaluation of new information not previously available. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from its current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which they are determined. Earnings per Share Basic earnings per share are computed by dividing net income (loss) (the numerator) by the weighted-average number of common shares outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to the computation of 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 potentially dilutive common stock equivalents such as stock options and restricted stock, had been exercised or vested. There were 167,910 and 232,821 anti-dilutive common stock equivalents at April 30, 2021 and April 30, 2020, respectively, which have been excluded from the calculation of diluted earnings per share. Fiscal Years Ended April 30, 2021 2020 Net income $ 1,541,019 $ 443,102 Weighted-average shares Basic 4,256,094 4,242,351 Effect of dilutive stock options 45,887 27,699 Diluted 4,301,981 4,270,050 Basic earnings per share $ 0.36 $ 0.10 Diluted earnings per share $ 0.36 $ 0.10 Revenue Recognition The Company recognizes revenue when control of the promised goods or services are transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company’s primary performance obligation to its customers is the production of finished goods electronic assembly products pursuant to purchase orders. The Company has concluded that control of the products it sells and transfers to its customers and an enforceable right to receive payment is customarily established at the point in time when the finished goods are shipped to its customers, or in some cases delivered pursuant to the specified shipping terms of each customer arrangement. With respect to consignment arrangements, control transfers and revenue is NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Revenue Recognition - Continued recognized at the point in time when the goods are shipped to the customer from the consignment location or when delivered to the customer (pursuant to agreed upon shipping terms). In those limited instances where finished goods delivered to the customer location are stored in a segregated area which are not controlled by the customer (title transfer) until they are pulled from the segregated area and consumed by the Company’s customer, revenue is recognized upon consumption. For tooling services, the Company’s performance obligation is satisfied at the point in time when the customer takes legal possession of dies or molds, which accounted for less than 1% of the Company’s revenue. For engineering, design, and testing services, the Company’s performance obligations are satisfied over time as the respective services are rendered as its customers simultaneously derive value from the Company’s performance. From the time that a customer purchase order is received and contract is established, the Company’s performance obligations are typically fulfilled within a few weeks after receipt of all material. The Company does not have any performance obligations that require more than 12 months to fulfill. Each customer purchase order sets forth the transaction price for the products and services purchased under that arrangement. The Company evaluates the credit worthiness of its customers and exercises judgment to recognize revenue based upon the amount the Company expects to be paid for each sales transaction it enters into with its customers. Some customer arrangements include variable consideration, such as volume rebates, some of which depend upon the Company’s customers meeting specified performance criteria, such as a purchasing level over a period of time. The Company exercises judgment to estimate the most likely amount of variable consideration at each reporting date. The Company’s typical payment terms are 30 days and its sales arrangements do not contain any significant financing component for its customers. The Company’s customer arrangements do not generate contract assets or liabilities that are material to the consolidated financial statements. The Company generally provides a warranty for workmanship, unless the assembly was designed by the Company, in which case it warrants assembly/design. The Company assembles and tests assemblies based on customers’ specifications prior to shipment. Historically, the amount of returns for workmanship issues has been de minimis under the Company’s standard or extended warranties. The Company does not provide its customers the option to purchase additional warranties and, therefore, the Company’s warranties are not considered a separate service or performance obligation. The Company utilizes the practical expedient to treat shipping and handling activities after the customer obtains control as fulfillment activities. The Company records shipping and handling costs as selling and administrative expenses and costs are accrued when revenue is recognized. The Company pays sales commissions to its sales representatives which may be considered as incremental costs to obtain a contract. However, since the recoverability period is less than one year, the Company utilizes the practical expedient provided by the new revenue recognition accounting standard that allows an entity to expense the costs of obtaining a contract as incurred. During fiscal year 2021, no revenues were recognized from performance obligations satisfied or partially satisfied in previous periods and no amounts were allocated to performance obligations that remain unsatisfied or partially unsatisfied at April 30, 2021. The Company is electing not to disclose the value of the remaining unsatisfied performance obligation with a duration of one year or less as permitted by the practical expedient in ASU 2014-09, “ Revenue from Contracts with Customers.” The Company had no material remaining unsatisfied performance obligations as of April 30, 2021, with an expected duration of greater than one year. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Revenue Recognition - Continued The majority of sales are made to U.S. based customers. The following table presents the Company’s revenue disaggregated by the principal end-user markets it serves: Year Ended April 30, Year Ended April 30, Net sales by end-market 2021 2020 Industrial Electronics $ 149,861,832 $ 158,972,238 Consumer Electronics 113,374,065 105,903,419 Medical / Life Sciences 14,482,775 16,166,825 Total Net Sales $ 277,718,672 $ 281,042,482 Shipping and Handling Costs The Company records shipping and handling costs for goods shipped to customers as selling and administrative expenses. Customers are typically invoiced for shipping costs and such amounts are included in net sales. Shipping and handling costs were not material to the financial statements for fiscal years 2021 or 2020. Fair Value Measurements Fair value measurements are determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs. The Company utilizes a fair value hierarchy based upon the observability of inputs used in valuation techniques as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, accounts receivable, note receivable, other receivables, accounts payable and accrued expenses which approximate fair value at April 30, 2021 and April 30, 2020, due to their short-term nature. The carrying amounts of the Company’s debt obligations approximate fair value based on future payments discounted at current interest rates for similar obligations or interest rates which fluctuate with the market. On April 30, 2018, the Company entered into an Asset Purchase Agreement with Wagz, Inc. (“Wagz”), whereby the Company sold certain assets to Wagz for $ 350,000 cash, in exchange for 600,000 shares of Wagz common stock and an earn-out based on sales by Wagz generated from use of the assets through July 31, 2022 . The earn-out is $ 6.00 per unit of a product specified in the asset purchase agreement and any upgrade to such product. As of April 30, 2021 no earn out has been realized. The fair value of the non-cash consideration consisted of $ 600,000 for the 600,000 shares of Wagz common stock which is recorded within other assets. The Company determined the fair value of the equity using the price per common share received by Wagz in the most recent financing transaction, a level 3 input. As of April 30, 2021, and April 30, 2020 the Company did not assign any value to the earn-out because any receipts from the earn-out are highly NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Fair Value of Financial Instruments - Continued uncertain and contingent upon Wagz selling the product specified in the asset purchase agreement between the Company and Wagz. Intangible Assets Intangible assets are comprised of finite life intangible assets including customer relationships. Finite life intangible assets are amortized on a straight line basis over their estimated useful lives of 7 years except for customer relationships which are amortized on an accelerated basis over their estimated useful life of 15 years. Impairment of Long-Lived Assets The Company reviews long-lived assets, including amortizable intangible assets, for impairment in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360: Property, Plant and Equipment . Property, machinery and equipment and finite life intangible assets are reviewed whenever events or changes in circumstances occur that indicate possible impairment. If events or changes in circumstances occur that indicate possible impairment, the Company first performs an impairment review based on an undiscounted cash flow analysis at the lowest level at which cash flows of the long-lived assets are largely independent of other groups of its assets and liabilities. This analysis requires management judgment with respect to changes in technology, the continued success of product lines, and future volume, revenue and expense growth rates. If the carrying value exceeds the undiscounted cash flows, the Company records an impairment, if any, for the difference between the estimated fair value of the asset group and its carrying value. The Company further conducts annual reviews of its long-lived asset groups for possible impairment. The Company’s analysis for fiscal year 2021 and 2020 did not indicate that any of its other long-lived assets were impaired. The Company has yet to experience material cancellations of orders; however, the potential impact of future disruptions, continued economic uncertainty over COVID-19 may have a significant adverse impact on the timing of delivery of customer orders and the levels of future customer orders. It is reasonably possible that these potential adverse impacts may result in the recognition of material impairments or other related charges in future periods. Investment in Wagz The Company has recorded an investment in Wagz Inc. (“Wagz”), a privately held company whose equity does not have a readily determinable fair value. As permitted by ASC 321, Investments - Equity Securities, paragraph 321-35-2, the Company has elected to carry its investment in Wagz equity at its cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or a similar investment of the same issuer until the investment no longer qualifies to be measured under paragraph 321-35-2. At April 30, 2021 and April 30, 2020, the Company continued to recognize the fair value of the Wagz common stock at $ 600,000 , which is recorded within other assets. On May 29, 2020, SigmaTron and Wagz, Inc. (“Wagz”), a privately held company in the pet technology market, entered into a Convertible Secured Promissory Note in the principal sum of up to $ 4,052,478 . On January 27, 2021, Wagz issued an additional Convertible Secured Promissory Note to the Company in the principal sum of up to $ 1,588,328 . On April 30, 2021, Wagz issued an additional Convertible Secured Promissory Note to the Company in the principal amount of $ 1,249,966 . On April 30, 2021, Wagz issued a Secured Promissory Note to the Company in the principal amount of $ 308,329 (collectively, the “Notes”). At April 30, 2021, $ 7,014,594 and $ 184,507 was outstanding under Note receivable and Other receivables, respectively, in the consolidated balance sheet. The Notes are due (the “Maturity Date”) on the earliest to occur of (a) December 31, 2021 or, if the closing of the Company’s proposed acquisition of Wagz (the “Closing”) does not occur due to the Company’s termination, that date which is twelve (12) months after the date of such termination, (b) upon the closing of a sale of all or substantially all of the assets or common stock of Wagz (other than the Closing), or (c) an Event of Default (as defined in the Notes). Interest NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Investment in Wagz – Continued is payable at the rate of four percent ( 4 %) per annum and is payable on the Maturity Date. The Notes are collateralized by substantially all assets of Wagz. On June 4, 2020, SigmaTron and Wagz, announced that they executed a Letter of Intent (“LOI”) relating to a proposed acquisition. Subject to the terms and conditions set forth in the LOI, SigmaTron expects to issue approximately 2,443,870 shares of SigmaTron common stock that would result in the stockholders of Wagz owning in the aggregate approximately one-third of the combined company. On July 19, 2021 the definitive agreement was signed. The parties expect the transaction to close by September 30, 2021 and it remains subject to achievement of certain milestones and satisfaction of conditions by both parties prior to Closing including the Company having determined that the Wagz Freedom Smart Collar™ meets certain criteria, and the approval by the stockholders of both SigmaTron and Wagz. In November 2020, Wagz sought short-term financing for its operations and secured a commitment from Angel Business Credit, LLC (“ABC”) for a loan of $ 250,000 conditioned on Wagz granting ABC a security interest in its assets and Gary R. Fairhead executing a personal guaranty. Mr. Fairhead is the Company’s President and CEO; his personal guaranty requires the approval of the Audit Committee of the Company’s Board of Directors. After consideration, the Audit Committee determined that Mr. Fairhead’s guaranty was in the best interests of the Company and approved the guaranty. The loan closed on November 12, 2020, and its principal, plus interest equal to $ 5,000 , were due on the maturity date, December 10, 2020. The loan was paid in full on December 8, 2020. As a result, Mr. Fairhead’s guaranty was cancelled and ABC’s security interest was terminated. Stock Incentive Plans Under the Company’s stock option plans, options to acquire shares of common stock have been made available for grant to certain employees. Each option granted has an exercise price of not less than 100 % of the market value of the common stock on the date of grant. The contractual life of each option is generally 10 years. The vesting of the grants varies according to the individual options granted. The Company measures the cost of employee services received in exchange for an equity award based on the grant date fair value and records that cost over the respective vesting period of the award. The Company has a restricted stock plan under which non-employee directors may acquire shares of common stock. The restricted stock plan has been approved by the Company’s stockholders. The restricted stock plan is interpreted and administered by the Compensation Committee of the Board of Directors. All awarded stock under the plan vests in six months from the date of grant. Awarded stock under this plan is granted at the closing price of the Company’s common stock on the date of grant. New Accounting Standards In June 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments .” ASU 2016-13, as amended by ASU 2019-04 and ASU 2019-05, introduces a new forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including trade receivables. The estimate of expected credit losses will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. This ASU also expands the disclosure requirements to enable users of financial statements to understand the entity’s assumptions, models and methods for estimating expected credit losses. For small reporting companies, ASU 2016-13 is effective for annual and interim reporting periods beginning after December 15, 2022, and the guidance is to be applied using the modified-retrospective approach. Earlier adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued New Accounting Standards - Continued In December 2019, the FASB issued ASU 2019-12, “ Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ”, which intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application of Topic 740. This guidance is effective for fiscal years beginning after December 15, 2020, including interim periods therein, and early adoption is permitted. Adoption of Topic 740 is not expected to have a material effect on the Company’s consolidated financial statements. If in a future interim reporting period the Company recognizes a year-to-date loss in excess of its forecasted full-year loss in a certain jurisdiction, the adoption of this ASU could affect how much tax benefit is recorded in an interim period related to that loss. In March 2020, the FASB issued ASU 2020-04, “ Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ”, which provides optional expedients and exceptions for a period of time to ease the potential burden in accounting for the transition from reference rates that are expected to be discontinued.

Prior to its payoff and termination, the U.S. Bank senior secured credit facility was due to expire on March 31, 2022 . On January 29, 2021, the Company paid the balance outstanding under the senior secured credit facility in the amount of $ 25,574,733 . The unamortized deferred financing costs of $ 158,476 were expensed in fiscal year 2021 upon extinguishment of the debt. On January 29, 2021, the Company entered into a Credit Agreement (the “Agreement”) with JPMorgan Chase Bank, N.A. (“Lender”), pursuant to which Lender has agreed to provide the Company with a secured credit facility maturing on January 29, 2026 , of which (a) up to $ 50,000,000 is available on a revolving loan basis, and (b) an aggregate of $ 6,500,000 was borrowed pursuant to two term loans (the “Facility”). The Facility is secured by substantially all of SigmaTron’ assets including mortgages on its two Illinois properties. The Facility allows the Company to choose among interest rates at which it may borrow funds for revolving loans: “CBFR Loans,” the interest on which is based on (A) the “REVLIBOR30 Rate” (as defined in the Agreement) unless the REVLIBOR30 Rate is not available, in which case the interest is generally the rate of interest last quoted by The Wall Street Journal as the “Prime Rate” in the U.S., plus (B) an applicable margin of 2.0 % (effectively 2.25 % per annum at April 30, 2021); or “Eurodollar Loans,” the interest on which is based on (X) an interest rate per annum (rounded upwards, if necessary, to the next 1/16 of 1%) equal to the LIBO Rate (as defined in the Agreement) for any interest period multiplied by the Standard Reserve Rate (as defined in the Agreement) plus (Y) an applicable margin of 2.0 %. Under the revolving portion of the Facility, the Company may borrow up to the lesser of (i) $ 50,000,000 or (ii) an amount equal to a percentage of the eligible receivable borrowing base plus a percentage of the inventory borrowing base. The Facility is collateralized by a lien on substantially all of the assets of the Company. Under the Agreement, a minimum Fixed Charge Coverage Ratio (“FCCR”) financial covenant of 1.10x is applicable only during an FCCR trigger period which occurs when (i) an event of default (as defined in the Agreement) has occurred and is continuing, and Lender has elected to impose a FCCR trigger period upon notice to the Company or (ii) availability falls below the greater of (a) 10 % of the revolving commitment and (b) the outstanding principal amount of the term NOTE G - LONG-TERM DEBT - Continued Notes Payable – Banks - Continued loans. The Company was not in a FCCR trigger period as of April 30, 2021. Deferred financing costs of $ 361,734 were capitalized during the fiscal year ended April 30, 2021 and will be amortized over the term of the Agreement. As of April 30, 2021, there was $ 24,967,668 outstanding and $ 15,947,990 of unused availability under the revolving Facility compared to an outstanding balance of $ 26,884,494 and $ 13,850,575 of unused availability under the U.S. Bank senior secured credit facility at April 30, 2020. As of April 30, 2021 and April 30, 2020, the unamortized amount offset against outstanding debt was $ 343,890 and $ 218,062 , respectively. On April 23, 2020, the Company received a PPP loan from U.S. Bank, as lender, pursuant to the Paycheck Protection Program of the CARES Act, as administered by the U.S. Small Business Administration (the “SBA”) in the amount of $ 6,282,973 (the “PPP Loan”). The PPP Loan, matures on April 23, 2022 . No additional collateral or guarantees were provided by the Company for the PPP Loan. The PPP Loan provides for customary events of default. Under the CARES Act, loan forgiveness may be available for the sum of documented payroll costs, rent payments, mortgage interest and covered utilities during the Covered Period, as defined by the SBA. The amount of loan forgiveness will be reduced if recipients terminate employees or reduce salaries during the covered period. The Company submitted its loan forgiveness application on March 26, 2021. The Company was notified of the forgiveness of the PPP Loan by the SBA on July 9, 2021 and it covers all principal and accrued interest. The accounting for the forgiveness will be reflected in the Company’s first quarter financial statements for fiscal year 2022. The Company will be required to repay any portion of the outstanding principal that is not forgiven, along with accrued interest, and it cannot provide any assurance that it will be eligible for loan forgiveness, or that any amount of the PPP Loan will ultimately be forgiven by the SBA. All aspects of the PPP Loan are subject to review by the SBA, including without limitation, the Company’s eligibility for and the size of the loan. If, despite the Company’s actions and certification that it satisfied all eligibility requirements for the PPP Loan, it is later determined that it violated applicable laws or was otherwise ineligible to receive the PPP Loan, it may be required to repay the PPP Loan in its entirety in a lump sum or be subject to additional penalties and interest. To the extent that all or part of the PPP Loan is not forgiven, the Company will be required to make payments, including interest accruing at an annual interest rate of 1.0 %, beginning on the date of disbursement. On March 15, 2019, the Company’s wholly-owned subsidiary, SigmaTron Electronic Technology Co., Ltd., entered into a credit facility with China Construction Bank. On January 26, 2021, the agreement was amended.

This legislation is aimed at providing relief for individuals and businesses impacted by the COVID-19 outbreak. The CARES Act includes several significant business tax provisions that, among other things, would temporarily eliminate the taxable income limit for certain net operating losses (NOL), allow businesses to carry back NOLs arising in 2018, 2019, and 2020 to the five prior tax years, accelerate refunds of corporate Alternative Minimum Tax credits, temporarily increase the business interest limitation under section 163(j), and allow for deferral of payroll taxes. The CARES Act also established the Paycheck Protection Program (“PPP”), to be administered by the SBA, whereby certain businesses are eligible for a loan to fund payroll expenses, rent, and related costs. The PPP Loan may be forgiven if the funds are used for payroll and other qualified expenses within certain limits. As described in Note G, the Company received a PPP Loan under the CARES Act of $ 6,282,973 . For federal income tax purposes, the CARES Act expressly provides that any forgiveness or cancellation of all or part of such loans will not be treated as income for tax purposes. IRS Revenue Ruling 2021-2 also clarified that deductions attributable to a PPP Loan that is later forgiven shall be disallowed. As of April 30, 2021 the PPP Loan has not been forgiven and thus the expenses have not been disallowed for federal income tax purposes. As of April 30, 2021, the Company does no t have a NOL carryforward for federal income tax purposes. The Company has state NOL carry-forwards totaling approximately $ 20,000 at April 30, 2021, that will begin to expire in fiscal year April 30, 2035 . The Company has foreign NOL carryforwards of $ 4,414,687 as of April 30, 2021, which will begin to expire in 2023 . The Company recognizes a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. With the exception of its foreign tax credits and foreign NOL described below, the Company determined it is more likely than not that it will realize its deferred tax assets due to the reversal of deferred tax liabilities and forecast of future earnings. The Company has established a valuation allowance of $ 1,060,636 on its NOL carryforwards and other deferred tax assets at one of its Chinese subsidiaries and its Vietnam subsidiary. Based on historical losses and forecasted future earnings the Company has determined that the tax benefit from such assets are not more likely than not to be realized. Cash and cash equivalents held internationally may be subject to foreign withholding taxes if repatriated to the U.S. Absent meeting an exception, unrepatriated foreign earnings generally remain subject to local country withholding taxes upon repatriation. The Company continues to apply its permanent reinvestment assertion on the cumulative amount of unremitted earnings of $ 4,779,000 as of April 30, 2021, from its foreign subsidiaries. NOTE I - INCOME TAX - Continued Unrecognized Tax Benefits The Company has not identified any uncertain tax positions or expects any to be taken in the Company’s tax returns. For the fiscal years ended April 30, 2021 and April 30, 2020, the amount of consolidated worldwide liability for uncertain tax positions that impacted the Company’s effective tax rate was $ 0 . Other Interest and penalties related to tax positions taken in the Company’s tax returns are recorded in income tax expense and miscellaneous selling, general and administrative expense, respectively, in the consolidated statements of operations. For the fiscal years ended April 30, 2021 and April 30, 2020, the amount included in the Company’s balance sheet for such liabilities was $ 0 . The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. With few exceptions, the Company is no longer subject to state, local or foreign examinations by tax authorities for tax years before fiscal year 2015.

Leases

Leases	12 Months Ended

Leases [Abstract]
Leases	NOTE L - LEASES The Company leases office and storage space, vehicles and other equipment under non-cancellable operating leases with initial terms typically ranging from 1 to 5 years. At contract inception, the Company reviews the facts and circumstances of the arrangement to determine if the contract is or contains a lease. The Company follows the guidance in Topic 842 to evaluate whether the contract has an identified asset; if the Company has the right to obtain substantially all economic benefits from the asset; and if the Company has the right to direct the use of the underlying asset. When determining if a contract has an identified asset, the Company considers both explicit and implicit assets, and whether the supplier has the right to substitute the asset. When determining if the Company has the right to direct the use of an underlying asset, the Company considers if they have the right to direct how and for what purpose the asset is used throughout the period of use and if they control the decision-making rights over the asset. The Company’s lease terms may include options to extend or terminate the lease. The Company exercises judgment to determine the term of those leases when extension or termination options are present and include such options in the calculation of the lease term when it is reasonably certain that it will exercise those options. The Company has elected to include both lease and non-lease components in the determination of lease payments. Payments made to a lessor for items such as taxes, insurance, common area maintenance, or other costs commonly referred to as executory costs, are also included in lease payments if they are fixed. The fixed portion of these payments are included in the calculation of the lease liability, while any variable portion would be recognized as variable lease expenses, when incurred. Variable payments made to third parties for these, or similar costs, such as utilities, are not included in the calculation of lease payments. At commencement, lease-related assets and liabilities are measured at the present value of future lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company exercises judgment in determining the incremental borrowing rate based on the information available at when the lease commences to measure the present value of future payments. Operating lease expense is recognized on a straight-line basis over the lease term. Finance lease cost includes amortization, which is recognized on a straight-line basis over the expected life of the leased asset, and interest expense, which is recognized following an effective interest rate method. Operating leases are included in other assets, current operating lease obligations, and operating lease obligations (less current portion) on the Company’s consolidated balance sheet. Finance leases are included in property, plant and equipment and current and long-term portion of finance lease obligations on the Company’s consolidated balance sheet. Short term leases with an initial term of 12 months or less are not presented on the balance sheet with expense recognized as incurred.

Under the CARES Act, forgiveness of a PPP Loan is available for the sum of documented payroll costs, covered rent payments, covered mortgage interest and covered utilities during the 24-week period beginning on the date of loan approval. The Company could be required to repay any portion of the outstanding principal of its PPP Loan that is not forgiven, along with accrued interest. If the PPP Loan is not forgiven, the Company would be required to pay the lender equal monthly payments of principal and interest as required to fully amortize by April 23, 2022 and any principal amount outstanding on the PPP Loan. The Company was notified of the forgiveness of the PPP Loan by the SBA on July 9, 2021 and it covers all principal and accrued interest. The accounting for the forgiveness will be reflected in the Company’s first quarter financial statements for fiscal year 2022. On May 29, 2020, SigmaTron and Wagz, Inc. (“Wagz”), a privately held company in the pet technology market, entered into a Convertible Secured Promissory Note in the principal sum of up to $ 4,052,478 . On January 27, 2021, Wagz issued an additional Convertible Secured Promissory Note to the Company in the principal sum of up to $ 1,588,328 . On April 30, 2021, Wagz issued an additional Convertible Secured Promissory Note to the Company in the principal amount of $ 1,249,966 . On April 30, 2021, Wagz issued a Secured Promissory Note to the Company in the principal amount of $ 308,329 (collectively, the “Notes”). At April 30, 2021, $ 7,014,594 and $ 184,507 was outstanding under Note receivable and Other receivables, respectively, in the consolidated balance sheet. The Notes are due (the “Maturity Date”) on the earliest to occur of (a) December 31, 2021 or, if the closing of the Company’s proposed acquisition of Wagz (the “Closing”) does not occur due to the Company’s termination, that date which is twelve (12) months after the date of such termination, (b) upon the closing of a sale of all or substantially all of the assets or common stock of Wagz (other than the Closing), or (c) an Event of Default (as defined in the Notes). Interest is payable at the rate of four percent ( 4 %) per annum and is payable on the Maturity Date. The Notes are collateralized by substantially all assets of Wagz. On June 4, 2020, SigmaTron and Wagz, announced that they executed a Letter of Intent (“LOI”) relating to a proposed acquisition. Subject to the terms and conditions set forth in the LOI, SigmaTron expects to issue approximately 2,443,870 shares of SigmaTron common stock that would result in the stockholders of Wagz owning in the aggregate approximately one-third of the combined company. On July 19, 2021 the definitive agreement was signed. The parties expect the transaction to close by September 30, 2021 and it remains subject to achievement of certain milestones and satisfaction of conditions by both parties prior to Closing including the Company having determined that the Wagz Freedom Smart Collar™ meets certain criteria, and the approval by the stockholders of both SigmaTron and Wagz.

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Apr. 30, 2021
Summary Of Significant Accounting Policies [Abstract]
Consolidation Policy	Consolidation Policy The consolidated financial statements include the accounts and transactions of SigmaTron International, Inc. (“SigmaTron”), its wholly-owned subsidiaries, Standard Components de Mexico, S.A., AbleMex S.A. de C.V., Digital Appliance Controls de Mexico, S.A. de C.V., Spitfire Controls (Vietnam) Co. Ltd., Spitfire Controls (Cayman) Co. Ltd. and SigmaTron International Trading Co., wholly-owned foreign enterprises Suzhou SigmaTron Electronics Co. Ltd., and SigmaTron Electronic Technology Co., Ltd. (collectively, “SigmaTron China”), and its international procurement office, SigmaTron Taiwan. The functional currency of the Mexican, Vietnamese and Chinese subsidiaries and procurement branch is the U.S. Dollar. Intercompany transactions are eliminated in the consolidated financial statements. The impact of currency fluctuations for the fiscal year ended April 30, 2021, resulted in net foreign currency transaction losses of $ 285,389 compared to net foreign currency losses of $ 285,654 in the prior year.
Use Of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made in preparing the consolidated financial statements include depreciation and amortization periods, the allowance for doubtful accounts, excess and obsolete reserves for inventory, deferred income, deferred taxes, uncertain tax positions, valuation allowance for deferred taxes and valuation of long-lived assets. Actual results could materially differ from these estimates.
Cash And Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and all highly liquid short-term investments with original maturities within three months of the purchase date.
Accounts Receivable	Accounts Receivable The majority of the Company’s accounts receivable are due from companies in the industrial electronics, consumer electronics and medical/life sciences industries. Credit is extended based on evaluation of a customer’s financial condition, and, generally, collateral is not required. Accounts receivable are due in accordance with agreed upon terms, and are stated at amounts due from customers net of an allowance for doubtful accounts. Accounts outstanding longer than the contractual payments terms are considered past due. The Company writes off accounts receivable when they are determined to be uncollectible. The Company has arrangements with various financial institutions to sell certain eligible accounts receivable balances from specific customers without recourse. The accounts receivable balances sold are at the election of the Company. The Company incurred fees for such sales, which are reflected as selling and administrative expenses on the Company’s income statement and were not material for the fiscal years ended April 30, 2021 and 2020. The accounts receivable balances are derecognized at the time of sale, as the Company does not have continuing involvement after the point of sale. During the years ended April 30, 2021 and April 30, 2020, the Company sold without recourse trade receivables of approximately $ 78,000,000 and $ 85,000,000 , respectively. Cash proceeds from these agreements are reflected as operating activities included in the change in accounts receivable in the Company's consolidated statements of cash flows.
Allowance For Doubtful Accounts	Allowance for Doubtful Accounts The Company’s allowance for doubtful accounts relates to receivables not expected to be collected from its customers. This allowance is based on management’s assessment of specific customer balances, considering the age of receivables and financial stability of the customer and a five year average of prior uncollectible amounts. If there is an adverse change in the financial condition of the Company’s customers, or if actual defaults are higher than provided for, an addition to the allowance may be necessary.
Inventories	Inventories Inventories are valued at cost. Cost is determined by an average cost method and the Company allocates labor and overhead to work-in-process and finished goods. In the event of an inventory write-down, the Company records expense to state the inventory at lower of cost or net realizable value. The Company establishes inventory reserves for shrinkage and excess and obsolete inventory. The Company records provisions for inventory shrinkage based on historical experience to account for unmeasured usage or loss. Of the Company’s raw materials inventory, a substantial portion has been purchased to fulfill committed future orders or for which the Company is contractually entitled to recover its costs from its customers. For the remaining raw materials inventory, a provision for excess and obsolete inventories is recorded for the difference between the cost of inventory and its estimated realizable value based on assumptions about future product demand and market conditions. Upon a subsequent sale or disposal of the impaired inventory, the corresponding reserve is relieved to ensure the cost basis of the inventory reflects any reductions. Actual results differing from these estimates could significantly affect the Company’s inventories and cost of products sold as the inventory is sold or otherwise relieved.
Property, Machinery And Equipment	Property, Machinery and Equipment Property, machinery and equipment are valued at cost. The Company provides for depreciation and amortization using the straight-line method over the estimated useful life of the assets: Buildings 20 years Machinery and equipment 5 - 12 years Office equipment and software 3 - 5 years Tools and dies 12 months Leasehold improvements lesser of lease term or useful life Expenses for repairs and maintenance are charged to selling and administrative expenses as incurred.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs consist of costs incurred to obtain the Company’s long-term debt and are amortized using the straight line method over the term of the related debt. Deferred financing fees of $ 353,438 and $ 279,740 net of accumulated amortization of $ 18,347 and $ 277,518 , respectively, as of April 30, 2021 and 2020, respectively, are deducted from long term debt on the Company’s consolidated balance sheet.
COVID-19 And CARES Act	COVID-19 and CARES Act A pandemic of respiratory diseases, including variants (commonly known as "COVID-19") began to spread globally, including to the United States, in early 2020. The full impact of the COVID-19 outbreak is inherently uncertain at the time of this report. The COVID-19 outbreak has resulted in travel restrictions and in some cases, prohibitions of non-essential activities, disruption and shutdown of certain businesses and greater uncertainty in global financial markets. The full extent to which COVID-19 impacts the Company’s business, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of the outbreak within the U.S., China, Mexico, Vietnam and Taiwan, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. Even after COVID-19 has subsided, the Company may continue to experience materially adverse impacts to its business as a result of its global economic impact, including any recession that has occurred or may occur in the future. There are no comparable recent events which may provide guidance as to the effect of the spread of COVID-19, and, as a result, the ultimate impact of COVID-19, or a similar health epidemic or pandemic, is highly uncertain and subject to change. The Company has adopted several measures in response to the COVID-19 outbreak. To date, the Company has been able to continue to meet the needs of its customers. Although the Company cannot estimate the length or gravity of the impact of the COVID-19 outbreak at this time, if the pandemic continues, it will have a material adverse effect on the Company’s results of future operations, financial position, and liquidity in fiscal year 2022. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued COVID-19 and CARES Act - Continued As further described in Note G, the Company has applied for, and has received, funds under the Paycheck Protection Program (“PPP Loan”) in the amount of $ 6,282,973 . The application for these funds required the Company to, in good faith, certify that the current economic uncertainty made the loan request necessary to support the ongoing operations of the Company. This certification further required the Company to take into account its then current business activity and its ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business. The receipt of these funds, and the forgiveness of the loan attendant to these funds, is dependent on the Company having initially qualified for the loan and qualifying for the forgiveness of such loan based on its adherence to the forgiveness criteria. Due to the size of the PPP Loan, it is subject to review by the U.S. Small Business Administration (“SBA”), which introduces a layer of uncertainty. If, despite the Company’s actions and certification that it satisfied all eligibility requirements for the PPP Loan, it is later determined that it violated applicable laws or was otherwise ineligible to receive the PPP Loan, the Company may be required to repay the PPP Loan in its entirety in a lump sum or be subject to additional penalties and interest, which could also result in adverse publicity and damage to the Company’s reputation. If these events were to transpire, they could have a material adverse effect on the Company’s business, results of operations and financial condition. The Company submitted its loan forgiveness application on March 26, 2021. The Company was notified of the forgiveness of the PPP Loan by the SBA on July 9, 2021 and it covers all principal and accrued interest. The accounting for the forgiveness will be reflected in the Company’s first quarter financial statements for fiscal year 2022.
Income Taxes	Income Taxes The Company’s income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated future taxes to be paid. The Company is subject to income taxes in both the U.S. and several foreign jurisdictions. Significant judgments and estimates by management are required in determining the consolidated income tax expense assessment. Deferred income tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities, and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. In evaluating the Company’s ability to recover its deferred tax assets within the jurisdiction from which they arise, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In projecting future taxable income, the Company begins with historical results and changes in accounting policies, and incorporates assumptions including the amount of future state, federal and foreign pre-tax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment and estimates by management about the forecasts of future taxable income and are consistent with the plans and estimates the Company uses to manage the underlying businesses. In evaluating the objective evidence that historical results provide, the Company considers three years of cumulative operating income and/or loss. Valuation allowances are established when necessary to reduce deferred income tax assets to an amount more likely than not to be realized. A tax benefit from an uncertain tax position may only be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Income Taxes - Continued The calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across its global operations. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Except as noted below, management is not aware of any such changes that would have a material effect on the Company’s results of operations, cash flows or financial position. The Company adjusts its tax liabilities when its judgment changes as a result of the evaluation of new information not previously available. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from its current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which they are determined.
Earnings Per Share	Earnings per Share Basic earnings per share are computed by dividing net income (loss) (the numerator) by the weighted-average number of common shares outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to the computation of 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 potentially dilutive common stock equivalents such as stock options and restricted stock, had been exercised or vested. There were 167,910 and 232,821 anti-dilutive common stock equivalents at April 30, 2021 and April 30, 2020, respectively, which have been excluded from the calculation of diluted earnings per share. Fiscal Years Ended April 30, 2021 2020 Net income $ 1,541,019 $ 443,102 Weighted-average shares Basic 4,256,094 4,242,351 Effect of dilutive stock options 45,887 27,699 Diluted 4,301,981 4,270,050 Basic earnings per share $ 0.36 $ 0.10 Diluted earnings per share $ 0.36 $ 0.10
Revenue Recognition	Revenue Recognition The Company recognizes revenue when control of the promised goods or services are transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company’s primary performance obligation to its customers is the production of finished goods electronic assembly products pursuant to purchase orders. The Company has concluded that control of the products it sells and transfers to its customers and an enforceable right to receive payment is customarily established at the point in time when the finished goods are shipped to its customers, or in some cases delivered pursuant to the specified shipping terms of each customer arrangement. With respect to consignment arrangements, control transfers and revenue is NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Revenue Recognition - Continued recognized at the point in time when the goods are shipped to the customer from the consignment location or when delivered to the customer (pursuant to agreed upon shipping terms). In those limited instances where finished goods delivered to the customer location are stored in a segregated area which are not controlled by the customer (title transfer) until they are pulled from the segregated area and consumed by the Company’s customer, revenue is recognized upon consumption. For tooling services, the Company’s performance obligation is satisfied at the point in time when the customer takes legal possession of dies or molds, which accounted for less than 1% of the Company’s revenue. For engineering, design, and testing services, the Company’s performance obligations are satisfied over time as the respective services are rendered as its customers simultaneously derive value from the Company’s performance. From the time that a customer purchase order is received and contract is established, the Company’s performance obligations are typically fulfilled within a few weeks after receipt of all material. The Company does not have any performance obligations that require more than 12 months to fulfill. Each customer purchase order sets forth the transaction price for the products and services purchased under that arrangement. The Company evaluates the credit worthiness of its customers and exercises judgment to recognize revenue based upon the amount the Company expects to be paid for each sales transaction it enters into with its customers. Some customer arrangements include variable consideration, such as volume rebates, some of which depend upon the Company’s customers meeting specified performance criteria, such as a purchasing level over a period of time. The Company exercises judgment to estimate the most likely amount of variable consideration at each reporting date. The Company’s typical payment terms are 30 days and its sales arrangements do not contain any significant financing component for its customers. The Company’s customer arrangements do not generate contract assets or liabilities that are material to the consolidated financial statements. The Company generally provides a warranty for workmanship, unless the assembly was designed by the Company, in which case it warrants assembly/design. The Company assembles and tests assemblies based on customers’ specifications prior to shipment. Historically, the amount of returns for workmanship issues has been de minimis under the Company’s standard or extended warranties. The Company does not provide its customers the option to purchase additional warranties and, therefore, the Company’s warranties are not considered a separate service or performance obligation. The Company utilizes the practical expedient to treat shipping and handling activities after the customer obtains control as fulfillment activities. The Company records shipping and handling costs as selling and administrative expenses and costs are accrued when revenue is recognized. The Company pays sales commissions to its sales representatives which may be considered as incremental costs to obtain a contract. However, since the recoverability period is less than one year, the Company utilizes the practical expedient provided by the new revenue recognition accounting standard that allows an entity to expense the costs of obtaining a contract as incurred. During fiscal year 2021, no revenues were recognized from performance obligations satisfied or partially satisfied in previous periods and no amounts were allocated to performance obligations that remain unsatisfied or partially unsatisfied at April 30, 2021. The Company is electing not to disclose the value of the remaining unsatisfied performance obligation with a duration of one year or less as permitted by the practical expedient in ASU 2014-09, “ Revenue from Contracts with Customers.” The Company had no material remaining unsatisfied performance obligations as of April 30, 2021, with an expected duration of greater than one year. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Revenue Recognition - Continued The majority of sales are made to U.S. based customers. The following table presents the Company’s revenue disaggregated by the principal end-user markets it serves: Year Ended April 30, Year Ended April 30, Net sales by end-market 2021 2020 Industrial Electronics $ 149,861,832 $ 158,972,238 Consumer Electronics 113,374,065 105,903,419 Medical / Life Sciences 14,482,775 16,166,825 Total Net Sales $ 277,718,672 $ 281,042,482
Shipping And Handling Costs	Shipping and Handling Costs The Company records shipping and handling costs for goods shipped to customers as selling and administrative expenses. Customers are typically invoiced for shipping costs and such amounts are included in net sales. Shipping and handling costs were not material to the financial statements for fiscal years 2021 or 2020.
Fair Value Measurements	Fair Value Measurements Fair value measurements are determined based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs. The Company utilizes a fair value hierarchy based upon the observability of inputs used in valuation techniques as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
Fair Value Of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, accounts receivable, note receivable, other receivables, accounts payable and accrued expenses which approximate fair value at April 30, 2021 and April 30, 2020, due to their short-term nature. The carrying amounts of the Company’s debt obligations approximate fair value based on future payments discounted at current interest rates for similar obligations or interest rates which fluctuate with the market. On April 30, 2018, the Company entered into an Asset Purchase Agreement with Wagz, Inc. (“Wagz”), whereby the Company sold certain assets to Wagz for $ 350,000 cash, in exchange for 600,000 shares of Wagz common stock and an earn-out based on sales by Wagz generated from use of the assets through July 31, 2022 . The earn-out is $ 6.00 per unit of a product specified in the asset purchase agreement and any upgrade to such product. As of April 30, 2021 no earn out has been realized. The fair value of the non-cash consideration consisted of $ 600,000 for the 600,000 shares of Wagz common stock which is recorded within other assets. The Company determined the fair value of the equity using the price per common share received by Wagz in the most recent financing transaction, a level 3 input. As of April 30, 2021, and April 30, 2020 the Company did not assign any value to the earn-out because any receipts from the earn-out are highly NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Fair Value of Financial Instruments - Continued uncertain and contingent upon Wagz selling the product specified in the asset purchase agreement between the Company and Wagz.
Intangible Assets	Intangible Assets Intangible assets are comprised of finite life intangible assets including customer relationships. Finite life intangible assets are amortized on a straight line basis over their estimated useful lives of 7 years except for customer relationships which are amortized on an accelerated basis over their estimated useful life of 15 years.
Impairment Of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews long-lived assets, including amortizable intangible assets, for impairment in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360: Property, Plant and Equipment . Property, machinery and equipment and finite life intangible assets are reviewed whenever events or changes in circumstances occur that indicate possible impairment. If events or changes in circumstances occur that indicate possible impairment, the Company first performs an impairment review based on an undiscounted cash flow analysis at the lowest level at which cash flows of the long-lived assets are largely independent of other groups of its assets and liabilities. This analysis requires management judgment with respect to changes in technology, the continued success of product lines, and future volume, revenue and expense growth rates. If the carrying value exceeds the undiscounted cash flows, the Company records an impairment, if any, for the difference between the estimated fair value of the asset group and its carrying value. The Company further conducts annual reviews of its long-lived asset groups for possible impairment. The Company’s analysis for fiscal year 2021 and 2020 did not indicate that any of its other long-lived assets were impaired. The Company has yet to experience material cancellations of orders; however, the potential impact of future disruptions, continued economic uncertainty over COVID-19 may have a significant adverse impact on the timing of delivery of customer orders and the levels of future customer orders. It is reasonably possible that these potential adverse impacts may result in the recognition of material impairments or other related charges in future periods.
Investment In Wagz	Investment in Wagz The Company has recorded an investment in Wagz Inc. (“Wagz”), a privately held company whose equity does not have a readily determinable fair value. As permitted by ASC 321, Investments - Equity Securities, paragraph 321-35-2, the Company has elected to carry its investment in Wagz equity at its cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or a similar investment of the same issuer until the investment no longer qualifies to be measured under paragraph 321-35-2. At April 30, 2021 and April 30, 2020, the Company continued to recognize the fair value of the Wagz common stock at $ 600,000 , which is recorded within other assets. On May 29, 2020, SigmaTron and Wagz, Inc. (“Wagz”), a privately held company in the pet technology market, entered into a Convertible Secured Promissory Note in the principal sum of up to $ 4,052,478 . On January 27, 2021, Wagz issued an additional Convertible Secured Promissory Note to the Company in the principal sum of up to $ 1,588,328 . On April 30, 2021, Wagz issued an additional Convertible Secured Promissory Note to the Company in the principal amount of $ 1,249,966 . On April 30, 2021, Wagz issued a Secured Promissory Note to the Company in the principal amount of $ 308,329 (collectively, the “Notes”). At April 30, 2021, $ 7,014,594 and $ 184,507 was outstanding under Note receivable and Other receivables, respectively, in the consolidated balance sheet. The Notes are due (the “Maturity Date”) on the earliest to occur of (a) December 31, 2021 or, if the closing of the Company’s proposed acquisition of Wagz (the “Closing”) does not occur due to the Company’s termination, that date which is twelve (12) months after the date of such termination, (b) upon the closing of a sale of all or substantially all of the assets or common stock of Wagz (other than the Closing), or (c) an Event of Default (as defined in the Notes). Interest NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued Investment in Wagz – Continued is payable at the rate of four percent ( 4 %) per annum and is payable on the Maturity Date. The Notes are collateralized by substantially all assets of Wagz. On June 4, 2020, SigmaTron and Wagz, announced that they executed a Letter of Intent (“LOI”) relating to a proposed acquisition. Subject to the terms and conditions set forth in the LOI, SigmaTron expects to issue approximately 2,443,870 shares of SigmaTron common stock that would result in the stockholders of Wagz owning in the aggregate approximately one-third of the combined company. On July 19, 2021 the definitive agreement was signed. The parties expect the transaction to close by September 30, 2021 and it remains subject to achievement of certain milestones and satisfaction of conditions by both parties prior to Closing including the Company having determined that the Wagz Freedom Smart Collar™ meets certain criteria, and the approval by the stockholders of both SigmaTron and Wagz. In November 2020, Wagz sought short-term financing for its operations and secured a commitment from Angel Business Credit, LLC (“ABC”) for a loan of $ 250,000 conditioned on Wagz granting ABC a security interest in its assets and Gary R. Fairhead executing a personal guaranty. Mr. Fairhead is the Company’s President and CEO; his personal guaranty requires the approval of the Audit Committee of the Company’s Board of Directors. After consideration, the Audit Committee determined that Mr. Fairhead’s guaranty was in the best interests of the Company and approved the guaranty. The loan closed on November 12, 2020, and its principal, plus interest equal to $ 5,000 , were due on the maturity date, December 10, 2020. The loan was paid in full on December 8, 2020. As a result, Mr. Fairhead’s guaranty was cancelled and ABC’s security interest was terminated.
Stock Incentive Plans	Stock Incentive Plans Under the Company’s stock option plans, options to acquire shares of common stock have been made available for grant to certain employees. Each option granted has an exercise price of not less than 100 % of the market value of the common stock on the date of grant. The contractual life of each option is generally 10 years. The vesting of the grants varies according to the individual options granted. The Company measures the cost of employee services received in exchange for an equity award based on the grant date fair value and records that cost over the respective vesting period of the award. The Company has a restricted stock plan under which non-employee directors may acquire shares of common stock. The restricted stock plan has been approved by the Company’s stockholders. The restricted stock plan is interpreted and administered by the Compensation Committee of the Board of Directors. All awarded stock under the plan vests in six months from the date of grant. Awarded stock under this plan is granted at the closing price of the Company’s common stock on the date of grant.
New Accounting Standards	New Accounting Standards In June 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments .” ASU 2016-13, as amended by ASU 2019-04 and ASU 2019-05, introduces a new forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including trade receivables. The estimate of expected credit losses will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. This ASU also expands the disclosure requirements to enable users of financial statements to understand the entity’s assumptions, models and methods for estimating expected credit losses. For small reporting companies, ASU 2016-13 is effective for annual and interim reporting periods beginning after December 15, 2022, and the guidance is to be applied using the modified-retrospective approach. Earlier adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements. NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued New Accounting Standards - Continued In December 2019, the FASB issued ASU 2019-12, “ Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ”, which intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application of Topic 740. This guidance is effective for fiscal years beginning after December 15, 2020, including interim periods therein, and early adoption is permitted. Adoption of Topic 740 is not expected to have a material effect on the Company’s consolidated financial statements. If in a future interim reporting period the Company recognizes a year-to-date loss in excess of its forecasted full-year loss in a certain jurisdiction, the adoption of this ASU could affect how much tax benefit is recorded in an interim period related to that loss. In March 2020, the FASB issued ASU 2020-04, “ Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ”, which provides optional expedients and exceptions for a period of time to ease the potential burden in accounting for the transition from reference rates that are expected to be discontinued. Regulators and market participants in various jurisdictions have undertaken efforts to eliminate certain reference rates and introduce new reference rates that are based on a larger and more liquid population of observable transactions. The amendments in this update apply only to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. In January 2021, the FASB issued clarification on the scope of relief related to the reference rate reform.
