(“Lender”), pursuant to which Lender provided the Company with a secured credit facility maturing on January 29, 2026, of which (a) up to $ 50,000,000 was 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 was secured by substantially all of SigmaTron’s assets including mortgages on its two Illinois properties. The Facility allowed 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 3.70 % per annum if in effect at July 31, 2022); 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 was able to 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 minus any reserves established by Lender. Under the Agreement, a minimum Fixed Charge Coverage Ratio (“FCCR”) financial covenant of 1.10 x 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 Note E - Long-term Debt - Continued the greater of (a) 10 % of the revolving commitment and (b) the outstanding principal amount of the term loans. The Company was not in a FCCR trigger period as of July 31, 2022. On November 17, 2021, the Company and Lender entered into an amendment of the Facility. The amended Facility allowed the Company to borrow under the revolving portion of the Facility up to the lesser of (i) $ 53,000,000 or (ii) an amount equal to a percentage of the eligible receivable borrowing base plus a percentage of the inventory borrowing base minus any reserves established by Lender. Further, the Facility was amended to allow in some circumstances customer deposits to be deemed eligible for collateral purposes. Effective as of December 31, 2021, Wagz joined the Facility as a loan guarantor, and granted to the Lender a security interest in all of its assets, including its intellectual property. On March 17, 2022, the Company and Lender entered into an amendment of the Facility. The amended Facility allowed the Company to borrow under the revolving portion of the Facility up to the lesser of (i) $ 60,000,000 or (ii) an amount equal to a percentage of the eligible receivable borrowing base plus a percentage of the inventory borrowing base minus any reserves established by Lender. Further, the Facility was amended to allow in some circumstances accounts arising from sales of inventory subject to bill and hold arrangements to be deemed eligible for collateral purposes, and to replace the interest rates based on the London interbank offered rate with rates based on the secured overnight financing rate as administered by the Federal Reserve Bank of New York. The Facility bears interest at the adjusted REVSOFR30 rate (as defined in the Credit Agreement). The interest rate per annum applicable to the Facility will be the Adjusted Term SOFR Rate (“SOFR”), plus the Applicable Margin of 2.0 %. On April 25, 2022, the Company and Lender entered into an amendment of the Facility. Under the amended Facility, Lender extended a term loan to the Company in the principal amount of $ 5,000,000 (the “FILO Term Loan”), the interest on which was based on (i) the “ Adjusted Term SOFR Rate” for a one-month Interest Period (each, as defined in the Agreement), plus (ii) an applicable margin of 4.0 % (effectively 5.70 % per annum at July 31, 2022). The FILO Term Loan would have matured within 120 days from the date of the amendment. The amount outstanding as of April 30, 2022 was $ 5,000,000 . There were no issuance costs associated with the FILO Term Loan. On July 18, 2022, a portion of the proceeds of the TCW Term Loan (as defined below) was used to pay in full the FILO Term Loan extended by Lender. The amount outstanding as of July 31, 2022 was $ 0 . On July 18, 2022, SigmaTron, Wagz and Lender amended and restated the Agreement by entering into an Amended and Restated Credit Agreement (“Credit Agreement”). The Facility, as amended, allows the Company to borrow on a revolving basis up to the lesser of (i) $ 70,000,000 or (ii) an amount equal to a percentage of the eligible receivable borrowing base plus a percentage of the inventory borrowing base minus any reserves established by Lender. The maturity date of the Facility was extended to July 18, 2027. Deferred financing costs of $ 208,407 and $ 128,733 were capitalized during the three month period ended July 31, 2022 and during the fiscal year ended April 30, 2022, respectively, which are amortized over the term of the Agreement.

The TCW Term Loan bears interest at a rate per annum based on SOFR, plus the Applicable Margin of 7.50 % (each as defined in the Term Loan Agreement). The TCW Term Loan has a SOFR floor of 1.00 %.

The PPP Loan was scheduled to mature on April 23, 2022. The Company was notified of the forgiveness of the PPP Loan by the SBA on July 9, 2021 and all principal and accrued interest were forgiven. The accounting for the forgiveness is reflected in the Company’s Statements of Income, in the three months ended July 31, 2021, as a non-cash gain upon extinguishment of long-term debt. 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 and terminated on January 6, 2022 . On January 17, 2022, the agreement was renewed, and is scheduled to expire on December 23, 2022.

Notes Payable – Buildings The Company’s Facility with Lender, entered into on January 29, 2021, also included two term loans, in the aggregate principal amount of $ 6,500,000 . The loans required the Company to pay aggregate principal payments in the amount of $ 36,111 per month for 60 months, plus monthly payments of interest thereon at (A) the REVLIBOR30 Rate, 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 2.5 % (effectively 4.20 % per annum if in effect at July 31, 2022); 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 2.5 %. Deferred financing costs of $ 10,050 were capitalized during fiscal year 2021 which were amortized over the term of the Agreement. As of July 31, 2022, the unamortized amount included as a reduction to long-term debt was $ 0 . A final aggregate payment of approximately $ 4,368,444 was due on or before January 29, 2026 .

Income Tax [Abstract]
Income Tax	Note F - Income Tax The income tax expense was $ 529,400 for the three month period ended July 31, 2022 compared to an income tax expense of $ 756,945 for the same period in the prior fiscal year. The Company’s effective tax rate was 27.77 % and 7.92 % for the quarters ended July 31, 2022 and 2021, respectively. The increase in effective tax rate is due primarily to tax exempt income recognized during the three month period ended July 31, 2022. Note F - Income Tax - Continued As described in Note E, 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. On January 6, 2021 the IRS issued Revenue Ruling 2021-02 allowing deductions for the payments of eligible expenses when such payments would result in the forgiveness of a loan under the PPP. The ruling supersedes previous IRS guidance stating that such deductions would be disallowed. The Company received full forgiveness of its PPP Loan on July 9, 2021. In accordance with the CARES Act and IRS Revenue Ruling 2021-02, the loan forgiveness amount was excluded from income for tax purposes. After SigmaTron’s merger with Wagz, Inc. (“Wagz”) , SigmaTron and Wagz (collectively, the “Company”) will file tax returns on a consolidated basis for periods ending after the merger. In evaluating the consolidated group’s ability to recover its deferred tax assets on a consolidated basis, and considering historical operating results of both companies, the consolidated group’s deferred tax assets are not more likely than not to be realized. Therefore, a valuation allowance was established on the group’s U.S. deferred tax assets during fiscal year 2022. The Company has established a valuation allowance of $ 4,129,312 on its federal and state NOL carryforwards and other U.S. deferred tax assets as of July 31, 2022. The Company had also established a valuation allowance of $ 334,203 on NOLs attributable to its Vietnam subsidiary as of July 31, 2022. Based on historical losses and forecasted future earnings, the Company had determined that the tax benefit from such assets are more likely than not to be realized. The Company’s valuation allowance was $ 4,463,515 and $ 4,543,819 as of July 31, 2022 and April 30, 2022, respectively. 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 $ 11,038,000 as of July 31, 2022.

Commitments And Contingencies [Abstract]
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 is 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.

Significant Accounting Policies

Summary Of Significant Accounting Policies [Abstract]
Significant Accounting Policies	Note H - Significant 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 Note H - Significant Accounting Policies - Continued amortization periods, the allowance for doubtful accounts, excess and obsolete reserves for inventory, deferred income, deferred taxes, valuation allowance for deferred taxes and valuation of goodwill and 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 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 - The following table presents the Company’s revenue disaggregated by the principal end-user markets it serves: Three Months Ended July 31, July 31, Net trade sales by end-market 2022 2021 Industrial Electronics $ 70,329,487 $ 47,244,892 Consumer Electronics 28,898,205 32,603,876 Medical / Life Sciences 6,345,164 5,890,666 Total Net Trade Sales $ 105,572,856 $ 85,739,434 During the three month period ending July 31, 2022, 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 July 31, 2022. The Company is electing not to disclose the amount 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 July 31, 2022, 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 Note H - Significant Accounting Policies - Continued 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 $ 4,463,515 and $ 4,543,819 as of July 31, 2022 and April 30, 2022, respectively. 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, that 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. 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. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

Leases

Leases	3 Months Ended

Leases [Abstract]
Leases	Note I – Leases The Company leases office and warehouse 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 “Leases” 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 it has the right to direct how and for what purpose the asset is used throughout the period of use and if it controls 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 includes 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 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 as expense is recognized as incurred.

Acquisition [Abstract]
Acquisition	Note J – Acquisition On December 31, 2021, the Company acquired 100 % of the stock of Wagz under the terms of the Agreement and Plan of Merger dated July 19, 2021, as amended by the First Amendment to Agreement and Plan of Merger dated December 7, 2021 (the “Merger Agreement”) . Wagz has developed and brought to market a high tech pet collar and has multiple other products in development. Wagz is an internet of things (“IoT”) company which both owns intellectual property and secures reoccurring revenue through subscriptions for its services. Prior to the acquisition, the Company had an investment in Wagz of $ 600,000 , Convertible Secured Promissory Notes issued by Wagz of $ 12,000,000 and Secured Promissory Notes issued by Wagz of $ 1,380,705 . Pursuant to the Merger Agreement, prior to the acquisition, the Convertible Secured Promissory Notes converted to 12,000,000 shares of Wagz common stock, resulting in a 25.5 % ownership in Wagz. The Company's 25.5 % equity interest in Wagz common stock was remeasured to fair value of $ 6,299,765 , resulting in a non-cash impairment charge of $ 6,300,235 within the Statements of Income during fiscal year 2022. Pursuant to the Merger Agreement, 2,443,870 shares of common stock of the Company were issued in the merger for a value of $ 25,245,177 , of which 1,546,592 shares are allocated to Wagz shareholders (excluding the Company) for a total value of $ 15,976,295 , and 897,278 shares are allocated to the Company and treated as treasury stock for a total value of $ 9,268,881 , recorded in the Statements of Changes in Stockholders’ Equity for the fiscal year 2022. The treasury shares were retired as of April 30, 2022. Note J – Acquisition – Continued The following table summarizes the consideration for the acquisition of Wagz: Consideration Issuance of 1,546,592 common stock of SigmaTron $ 15,976,295 Fair value of consideration transferred 15,976,295 Secured Promissory Notes 1,380,173 Fair value of SigmaTron's equity interest in Wagz held prior to the business combination 6,299,765 $ 23,656,233 The following table presents the purchase price allocation for Wagz. The Company is accounting for the acquisition under the acquisition method and is required to measure identifiable assets acquired and liabilities assumed of the acquiree at fair value on the closing date. The fair value of the majority of the assets was determined by a third party valuation firm using management estimates and assumptions including intangible assets of $ 9,730,000 for patents and $ 1,230,000 for trade names. The appropriate fair values of the assets acquired and liabilities assumed are based on estimates and assumptions. The excess consideration was recorded as goodwill of $ 13,320,534 , all of which is non-deductible for tax purposes. Goodwill represents future economic benefits arising from other assets acquired that could not be individually identified including workforce additions, growth opportunities, and increased presence in the Pet Tech market. The recorded goodwill has been assigned to the Pet Tech reportable segment. Cash $ 508,274 Working capital 224,046 Property, plant and equipment 201,839 Acquired intangible assets 10,960,000 Right-of-use operating lease assets 647,076 Other assets 6,000 Operating lease obligations ( 647,077 ) Deferred tax liability ( 215,000 ) Other liabilities ( 1,349,459 ) Goodwill 13,320,534 Fair value of purchase consideration $ 23,656,233 Note J – Acquisition – Continued The intangible assets acquired in the Wagz acquisition consisted of the following: Expected Weighted Amortization Fair Value Period Trade name $ 1,230,000 20 years Patents 9,730,000 18 years $ 10,960,000 The fair value recorded as of April 30, 2022 is based on significant inputs that are not observable in the market and thus represents a fair value measurement categorized within Level 3 of the fair value hierarchy. The fair value of the acquired trade names and patents was determined using the relief from royalty method, which is a risk-adjusted discounted cash flow approach. The relief from royalty method values an intangible asset by estimating the royalties saved through ownership of the asset. The relief from royalty method requires identifying the future revenue that would be generated by the intangible asset, multiplying it by a royalty rate deemed to be avoided through ownership of the asset and discounting the projected royalty savings amounts back to the acquisition date using the internal rate of return.

Significant Accounting Policies (Policy)	3 Months Ended
	Jul. 31, 2022
Summary Of Significant 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 Note H - Significant Accounting Policies - Continued amortization periods, the allowance for doubtful accounts, excess and obsolete reserves for inventory, deferred income, deferred taxes, valuation allowance for deferred taxes and valuation of goodwill and 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 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 July 31, July 31, Net trade sales by end-market 2022 2021 Industrial Electronics $ 70,329,487 $ 47,244,892 Consumer Electronics 28,898,205 32,603,876 Medical / Life Sciences 6,345,164 5,890,666 Total Net Trade Sales $ 105,572,856 $ 85,739,434 During the three month period ending July 31, 2022, 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 July 31, 2022. The Company is electing not to disclose the amount 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 July 31, 2022, 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 Note H - Significant Accounting Policies - Continued 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 $ 4,463,515 and $ 4,543,819 as of July 31, 2022 and April 30, 2022, respectively.
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, that 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. 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. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.
