(“SigmaTron”), SigmaTron’s 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 wholly-owned foreign enterprises Wujiang SigmaTron Electronics Co., Ltd. and SigmaTron Electronic Technology Co., Ltd. (“SigmaTron China”) and international procurement office SigmaTron Taiwan branch (collectively, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, the condensed consolidated financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and six month period ended October 31, 2020 is not necessarily indicative of the results that may be expected for the year ending April 30, 2021. The condensed consolidated balance sheet at April 30, 2020, was derived from audited annual financial statements but does not contain all of the footnotes disclosures from the annual financial statements. For further information, refer to the condensed consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended April 30, 2020.  COVID-19 and CARES Act  A pandemic of respiratory disease (abbreviated "COVID-19") began to spread globally, including to the United States, in early 2020. On March 11, 2020, the World Health Organization (WHO) declared COVID-19 to be a public health emergency of international concern. 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. Note B - Basis of Presentation - Continued  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 2021.  On March 27, 2020, President Trump signed into law the “Coronavirus Aid, Relief, and Economic Security (CARES) Act.” The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations, increased limitations on qualified charitable contributions, and technical corrections to tax depreciation methods for qualified improvement property. It also appropriated funds for the U.S. Small Business Administration (“SBA”) Paycheck Protection Program (“PPP Loan”) loans that are forgivable in certain situations to promote continued employment, as well as Economic Injury Disaster Loans to provide liquidity to small businesses harmed by COVID-19.  As further described in Note E, the Company has applied for, and has received, funds under the 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 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 future adherence to the forgiveness criteria.  Due to the size of the PPP Loan, it is subject to review, 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, 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, financial condition and liquidity in fiscal year 2021 and beyond.

The credit facility is collateralized by substantially all of the Company’s domestically located assets. The facility allows the Company to choose among interest rates at which it may borrow funds: the bank fixed rate of five percent or LIBOR plus one and one half percent (effectively 1.75% at October 31, 2020). Interest is due monthly.  On July 16, 2018, the Company and U.S. Bank entered into an amendment of the revolving line of credit under the senior secured credit facility. The amended revolving credit facility allows the Company to borrow up to the lesser of (i) $45,000,000 (the “Revolving Line Cap”) less reserves or (ii) the Borrowing Base, but no more than 90% of the Company’s Revolving Line Cap, except that the 90% limitation will expire if (i) the Company’s actual revolving loans for 90 consecutive days after the amendment’s effective date are less than 80% of the Company’s Borrowing Base and (ii) the Company maintains a Fixed Charge Coverage Ratio of 1.2 to 1.0 for four consecutive quarters. The amendment also imposes sublimits on categories of inventory of $10,500,000 on raw materials, $10,000,000 on finished goods and $28,000,000 on all eligible inventory.  On December 13, 2018, the Company and U.S. Bank entered into an amendment of the revolving credit facility. The amendment provides an exception to otherwise ineligible foreign receivables for up to $3,000,000 of receivables paid by certain enumerated account debtors outside of the U.S. and Canada.   Note E - Long-term Debt - Continued  On July 15, 2020 and August 7, 2020, the Company and U.S. Bank entered into amendments of the revolving credit facility. The amendments revised the Fixed Charge Coverage Ratio.  On September 8, 2020, the Company and U.S. Bank entered into an amendment of the revolving credit facility. The amendment allows the Company to borrow up to the lesser of (i) the Revolving Line Cap less reserves or (ii) the Borrowing Base, but no more than 80% of the Company’s Revolving Line Cap. The amendment also imposes sublimits on categories of other investments to $4,000,000 .  As of October 31, 2020, there was $25,500,000 outstanding and $4,286,052 of unused availability under the U.S. Bank facility compared to an outstanding balance of $26,884,494 and $13,850,575 of unused availability at April 30, 2020.

The PPP Loan, in the form of a promissory note, 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 24-week period beginning on the date of loan disbursement. The amount of loan forgiveness will be reduced if recipients terminate employees or reduce salaries during the covered period. The Company may 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. The review procedures have not been made public. The Company cannot predict the outcome of that review nor be assured that all or any part of the PPP Loan will be forgiven. 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.

Income Tax [Abstract]
Income Tax	Note F - Income Tax  The income tax expense was $442,943 for the three month period ended October 31, 2020 compared to an income tax expense of $316,106 for the same period in the prior fiscal year. The Company’s effective tax rate was 41.40% and 32.35% for the quarters ended October 31, 2020 and 2019, respectively. The income tax expense was $222,109 for the six month period ended October 31, 2020 compared to an income tax expense of $563,221 for the same period in the prior fiscal year. The Company’s effective tax rate was (429.63)% and 35.52% for the six month period ended October 31, 2020 and 2019, respectively. The increase in income tax expense and effective tax rate for the three month period ended October 31, 2020 compared to the same period in the previous year is due to an increase in income and variations in income earned by jurisdiction in the current period compared to the same period in the previous year. The decrease in income tax expense and effective tax rate for the six month period ended October 31, 2020 compared to the same period in the previous year is due to a decrease in income in the current six month period compared to the same period in the previous year. The negative effective tax rate in the current six month period is due to an overall pre-tax loss recognized in the current period but recognition of tax expense due to the mix of income by jurisdiction.  As described in Note E, the Company received a PPP Loan under the CARES Act of $6,282,963. 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. It is expected, however, that if the loan is deemed forgiven any deductions for the covered expenses that gave rise to the loan forgiveness will be disallowed to prevent a double tax benefit. As of October 31, 2020, the loan has not been forgiven and thus the expenses have not been disallowed for federal income tax purposes. Note F - Income Tax - Continued  On November 18, 2020 the IRS issued Revenue Ruling 2020-27 which holds that a taxpayer’s covered expenses are not deductible if the taxpayer reasonably expects the loan to be forgiven. If the Company’s eligible expenses are deemed nondeductible prior to loan forgiveness, it is expected that the Company’s current tax liability will increase and that a deferred tax asset will be established related to those expenses. The Company has not changed its plans to indefinitely reinvest the earnings of the Company’s foreign subsidiaries. The cumulative amount of unremitted earnings for which U.S. income taxes have not been recorded is $4,681,000 as of October 31, 2020.

Commitments And Contingencies	Note G - Commitments and Contingencies  From time to time the Company is involved in legal proceedings, claims or investigations that are incidental to the conduct of the Company’s business. In future periods, the Company could be subjected to cash cost or non-cash charges to earnings if any of these matters are resolved on unfavorable terms. However, although the ultimate outcome of any legal matter cannot be predicted with certainty, based on present information, including management’s assessment of the merits of any particular claim, the Company does not expect that these legal proceedings or claims will have any material adverse impact on its future consolidated financial position, results of operations or cash flows.

Critical Accounting Policies [Abstract]
Critical Accounting Policies	 Note H - Critical Accounting Policies  Management Estimates and Uncertainties - 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, reserves for inventory, lower of cost or net realizable value 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.  The potential impact of future disruptions and 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 of the Company’s long-lived assets or other related charges in future periods. Note H - Critical Accounting Policies - Continued  Revenue Recognition - The following table presents the Company’s revenue disaggregated by the principal end-user markets it serves:    Three Months Ended Six Months Ended  October 31, October 31,  Net trade sales by end-market 2020 2019 2020 2019  Industrial Electronics $ 35,654,079 $ 41,398,201 $ 72,271,337 $ 84,246,913  Consumer Electronics 30,671,077 28,815,556 51,839,316 55,474,743  Medical / Life Sciences 3,293,268 4,641,555 6,032,727 9,143,637  Total Net Trade Sales $ 69,618,424 $ 74,855,312 $ 130,143,380 $ 148,865,293   During the three and six month periods ending October 31, 2020, 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 October 31, 2020. 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 October 31, 2020, with an expected duration of greater than one year.  Income Tax - 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. The Company’s valuation allowance was $ 645,538 and $ 989,194 as of October 31, 2020 and April 30, 2020, respectively.  Investment in Wagz - As more fully described in Note I - Related Parties, the Company has recorded an investment in Wagz Inc. (“Wagz”), a privately held company whose equity does not have a readily Note H - Critical Accounting Policies - Continued  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 October 31, 2020 and April 30, 2020, the Company continued to recognize the fair value of the Wagz common stock at $600,000 .  On May 29, 2020, Wagz entered into a Convertible Secured Promissory Note with the Company in the principal sum of up to $4,052,478 . The outstanding principal amount of the Note is due and payable on the earliest to occur of (1) August 31, 2021 ; (2) upon the closing of a sale of all or substantially all of the assets or common stock of Wagz; or (3) an event of default (the Maturity Date). Interest is payable at the rate of four percent ( 4% ) per annum and is payable on the Maturity Date. The Note is collateralized against substantially all assets of Wagz. At October 31, 2020, $3,778,179 was outstanding under other receivables compared to $768,500 at April 30, 2020.  On June 4, 2020, the Company and Wagz announced that they ha d executed a letter of intent (“LOI”) relating to a proposed business combination. Subject to the terms and conditions set forth in the LOI, the Company expects to issue approximately 2,270,000 shares of its common stock that would result in the stockholders of Wagz owning in the aggregate approximately one-third of the combined company. The parties expect the transaction to close by the end of the third quarter of fiscal year 2021 and the acquisition remains subject to achievement of certain milestones and satisfaction of conditions by both parties prior to closing such as finalizing a material definitive agreement, the Company raising additional capital that it projects will be needed for the expanded operations, and the approval by the stockholders of both the Company and Wagz.  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 for annual and interim reporting periods beginning after December 15, 2018. The Company is currently evaluating the new guidance and has not determined the impact this ASU may have on its consolidated financial statements.  In December 2019, the FASB issued ASU 2019-12, “ Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ”, which simplifies accounting for income taxes by removing certain exceptions to intra-period allocations, investments, calculations in interim periods and to improve consistent application. ASU 2019-12 is effective for annual and interim reporting periods beginning  Note H - Critical Accounting Policies – Continued  after December 15, 2020. The Company is currently evaluating the new guidance and has not determined the impact this ASU may have on its consolidated financial statements.  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 guidance 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 changes provide optional expedients and exceptions for applying US GAAP to contract, hedging relationships and other transactions affected by reference rate reform. ASU 2020-04 is effective for all entities as of March 12, 2020 and can be adopted no later than December 31, 2022. The Company is currently evaluating the new guidance and has not determined the impact this ASU may have on its consolidated financial statements .

Related Parties [Abstract]
Related Parties	Note I - Related Parties  In March 2015, two of the Company’s executive officers invested in a start-up customer, Petzila, Inc. (“Petzila”). The executive officers’ investments constituted less than 2% (individually and in aggregate) of the outstanding beneficial ownership of Petzila, according to information provided by Petzila to the executive officers.  On April 30, 2018, the Company foreclosed on its security interest and held a public sale of the assets in accordance with the requirements of Article 9 of the California Uniform Commercial Code. The Company acquired all of the assets of Petzila as the winning bidder at the public sale by a credit bid of $3,500,000 , the aggregate amount of Petzila’s liability to the company. Concurrent with the foreclosure sale, the Company entered into an Asset Purchase Agreement with Wagz whereby the Company sold the assets to Wagz for $350,000 cash, 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.  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. The Company did not assign any value to the earn-out because any receipts from the earn-out are highly uncertain and contingent upon Wagz selling the product specified in the asset purchase agreement between the Company and Wagz. Accordingly, the Company recognized the fair value of the assets received from Wagz and derecognized the receivables from Petzila.  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 Note I - Related Parties – Continued  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 , are 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. 

Leases

Leases [Abstract]
Leases	Note J – 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  Note J – Leases – Continued  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.

Critical Accounting Policies [Abstract]
Management Estimates And Uncertainties	Management Estimates and Uncertainties - 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, reserves for inventory, lower of cost or net realizable value 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.  The potential impact of future disruptions and 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 of the Company’s long-lived assets or other related charges in future periods.
Revenue Recognition	Revenue Recognition - The following table presents the Company’s revenue disaggregated by the principal end-user markets it serves:    Three Months Ended Six Months Ended  October 31, October 31,  Net trade sales by end-market 2020 2019 2020 2019  Industrial Electronics $ 35,654,079 $ 41,398,201 $ 72,271,337 $ 84,246,913  Consumer Electronics 30,671,077 28,815,556 51,839,316 55,474,743  Medical / Life Sciences 3,293,268 4,641,555 6,032,727 9,143,637  Total Net Trade Sales $ 69,618,424 $ 74,855,312 $ 130,143,380 $ 148,865,293   During the three and six month periods ending October 31, 2020, 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 October 31, 2020. 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 October 31, 2020, with an expected duration of greater than one year.
Income Tax	Income Tax - 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. The Company’s valuation allowance was $ 645,538 and $ 989,194 as of October 31, 2020 and April 30, 2020, respectively.
Investment In Wagz	Investment in Wagz - As more fully described in Note I - Related Parties, the Company has recorded an investment in Wagz Inc. (“Wagz”), a privately held company whose equity does not have a readily Note H - Critical Accounting Policies - Continued  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 October 31, 2020 and April 30, 2020, the Company continued to recognize the fair value of the Wagz common stock at $600,000 .  On May 29, 2020, Wagz entered into a Convertible Secured Promissory Note with the Company in the principal sum of up to $4,052,478 . The outstanding principal amount of the Note is due and payable on the earliest to occur of (1) August 31, 2021 ; (2) upon the closing of a sale of all or substantially all of the assets or common stock of Wagz; or (3) an event of default (the Maturity Date). Interest is payable at the rate of four percent ( 4% ) per annum and is payable on the Maturity Date. The Note is collateralized against substantially all assets of Wagz. At October 31, 2020, $3,778,179 was outstanding under other receivables compared to $768,500 at April 30, 2020.  On June 4, 2020, the Company and Wagz announced that they ha d executed a letter of intent (“LOI”) relating to a proposed business combination. Subject to the terms and conditions set forth in the LOI, the Company expects to issue approximately 2,270,000 shares of its common stock that would result in the stockholders of Wagz owning in the aggregate approximately one-third of the combined company. The parties expect the transaction to close by the end of the third quarter of fiscal year 2021 and the acquisition remains subject to achievement of certain milestones and satisfaction of conditions by both parties prior to closing such as finalizing a material definitive agreement, the Company raising additional capital that it projects will be needed for the expanded operations, and the approval by the stockholders of both the Company and Wagz.
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 for annual and interim reporting periods beginning after December 15, 2018. The Company is currently evaluating the new guidance and has not determined the impact this ASU may have on its consolidated financial statements.  In December 2019, the FASB issued ASU 2019-12, “ Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ”, which simplifies accounting for income taxes by removing certain exceptions to intra-period allocations, investments, calculations in interim periods and to improve consistent application. ASU 2019-12 is effective for annual and interim reporting periods beginning  Note H - Critical Accounting Policies – Continued  after December 15, 2020. The Company is currently evaluating the new guidance and has not determined the impact this ASU may have on its consolidated financial statements.  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 guidance 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 changes provide optional expedients and exceptions for applying US GAAP to contract, hedging relationships and other transactions affected by reference rate reform. ASU 2020-04 is effective for all entities as of March 12, 2020 and can be adopted no later than December 31, 2022. The Company is currently evaluating the new guidance and has not determined the impact this ASU may have on its consolidated financial statements .
