Application of new and amended standards and interpretations and standards not in force yet	3. Application of new and amended standards and interpretations and standards not in force yet The consolidated financial statements of Grupo Simec, S.A.B. de C.V. and its Subsidiaries for the periods presented have been prepared in accordance with the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB). IFRS also includes all current International Accounting Standards (IAS), in force, as well as all related interpretations issued by the IFRS Interpretations Committee (IFRIC), including those issued previously by the Standing Interpretations Committee. The company applied the effective IFRS as of December 31, 2021. International Financial Reporting Standards, not in force yet. Following are the amendments that could have an effect on Simec financial information, which were issued by the IASB (International Accounting Standards Board) but are not yet effective as of the date of these financial statements. Amendments are effective as of 2022: In May 2020, the following amendments were issued: Reference to the conceptual framework IFRS 3.- Business Combinations, the amendments correspond only to refer to the conceptual framework. Onerous contracts: Cost of fulfilling a contract. IAS 37.- Provisions, Contingent Liabilities and Contingent Assets; this standard defines an onerous contract in which the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it. The amendments clarify that for the purpose of assessing whether a contract is onerous, the cost of fulfilling the contract includes both the incremental costs of fulfilling that contract and an allocation of other costs that relate directly to fulfilling contracts. Property, plant and equipment: Revenues from the use previously foreseen IFRS 16.- Property, plant and equipment, this amendment prohibits an entity from deducting from the cost of property, plant and equipment amounts received from selling items produced while the company is preparing the asset for its intended use. Instead, a company will recognize such sales proceeds and related cost in profit or loss. Also in May 2020, annual improvements to IFRS Standards 2018-2020 were issued, effective January 1, 2022. IFRS 1 First-time Adoption of International Financial Reporting Standards Purpose of improvement: Some options are established for the application of the Standards to Subsidiaries as a first-time adopter of IFRS IFRS 9 Financial Instruments. Purpose of improvement: This IFRS establishes that a substantial modification of the current conditions of an existing financial liability or part thereof shall be accounted for as a cancellation of the original financial liability and the recognition of a new financial liability. This amendment establishes that the conditions will be substantially different if the discounted present value of the cash flows under the new terms, including any fees paid net of any fees received and discounted using the original effective interest rate, is at least 10% different from the discounted present value of the remaining cash flows of the original financial liability Amendments applicable as of 2023: In January 2020, the IASB issued an amendment to IAS 1.- Presentation of Financial Statements, which clarifies that in order to reclassify a current liability as a non-current liability, the requirement for an entity to have the right to defer settlement of the liability for at least 12 months after the reporting period. At the effective date of this amendment, July 2020, it was deferred until January 1, 2023. In February 2021, the following amendments were issued: IAS 1.- Presentation of financial statements, the modification is that an entity must disclose its material information on accounting policies instead of its significant accounting policies. IAS 8.- Accounting policies, changes in accounting estimates and errors, this standard is modified to clarify how entities must distinguish between changes in accounting policies and changes in accounting estimates. In May 2021, the IASB issued an amendment to IAS 12.- Income Tax, which clarifies the accounting for deferred tax on transactions that, at the time of the transaction, give rise to equal taxable temporary differences and deductibles. In specific circumstances, entities are exempt from recognizing deferred taxes when they recognize assets or liabilities for the first time. The amendments clarify that the exemption does not apply to transactions for which entities recognize both an asset and a liability and that give rise to equal taxable and deductible temporary differences. This may be the case for transactions such as leases and decommissioning, restoration and similar obligations. Entities are required to recognize deferred taxes on such transactions. This Standard modifies IFRS 1.- Adoption for the first time of the International Financial Reporting Standards, to establish that deferred taxes related to leases and dismantling, restoration and similar obligations are recognized by those who adopt for the first time on the date of transition to International Financial Reporting Standards, despite the exemption established in IAS 12. At the date of issuance of our consolidated financial statements, these new standards have not had any effect on our financial information.

Disclosure of basis of preparation of financial statements [text block] [Abstract]
Basis of preparation and presentation of the consolidated financial statements	4. Basis of preparation and presentation of the consolidated financial statements The consolidated financial statements have been prepared in accordance with IFRS as discussed in Note 3, based on historical costs. Historical cost is generally based on the fair value of the consideration given in exchange for assets. Consolidation basis Within the consolidation process, adjustments are made to the financial statements of the subsidiaries to adapt their accounting policies so that they are aligned with those used by the Company. All significant intercompany transactions and balances between the consolidated companies are eliminated during consolidation. Changes in investments in subsidiaries of the Company that do not result in a loss of control are recorded as equity transactions. The book value of the company’s non-controlling investments and shares is adjusted to reflect changes in the corresponding investments in subsidiaries. Any difference between the amount by which non-controlling shares are adjusted and the fair value of the consideration paid or received is recognized directly and is attributed to the owners of the company. When the company loses control of a subsidiary, the profit or loss in the provision is calculated as the difference between (i) the sum of the fair value of the consideration received and the fair value of any retained ownership interest and (ii) the prior book value of assets (including commercial credit) and liabilities of the subsidiary and any non-controlling participation. The amounts previously recognized in other comprehensive income items related to the subsidiary are recorded (that is, reclassified to profit or loss or transferred directly to retained earnings) in the same manner established for the case of the disposal of significant assets or liabilities. The fair value of any investment retained by the former subsidiary on the date of loss of control is regarded as the fair value for initial recognition in its subsequent accounting treatment, according to IAS 39, financial instruments: Recognition and valuation, or, where appropriate, the cost in the initial recognition of an investment in an associate or entity under joint control. As of December 31, 2021, and 2020, the subsidiaries of Grupo Simec, S.A.B. de C.V. included in the consolidation are the following: Percentage of equity owned 2021 2020 Subsidiaries established in Mexico: Compañía Siderúrgica de Guadalajara, S.A. de C.V. 99.99 % 99.99 % Arrendadora Simec, S.A. de C.V. 100.00 % 100.00 % Simec International, S.A. de C.V. 100.00 % 100.00 % Compañía Siderúrgica del Pacifico, S.A. de C.V. 99.99 % 99.99 % Coordinadora de Servicios Siderúrgicos de Calidad, S.A. de C.V.

Conversion of foreign subsidiaries financial statements – The Effects of Changes in Foreign Exchange Rates The U.S. dollar (US Dollar or USD$) was considered as the functional currency of all the U.S. subsidiaries and Brazilian real for subsidiaries established in Brazil; therefore, the financial statements of these subsidiaries abroad were converted to Mexican pesos applying: - The exchange rates at the balance sheet date, to all assets, liabilities and stockholder´s equity. - The historical exchange rate at revenues, costs and expenses. The conversion differences are carried directly to the consolidated statements of comprehensive income as other comprehensive income under the caption translation effects of foreign subsidiaries. Relevant exchange rates used in the conversion of the financial statements of foreign subsidiaries were as follows (Mexican pesos per one U.S. dollar): Current exchange rate as of December 31, 2021 20.52 Current exchange rate as of December 31, 2020 19.95 Average exchange rate for the year ended December 31, 2021 (*) 20.28 Average exchange rate for the year ended December 31, 2020 (*) 21.49 Current exchange rate as of May 17, 2022 20.14 (*) Average exchange rate used to translate revenues, costs and expenses of the companies mentioned above. b. Business combinations – At the date of acquisition, the identifiable assets acquired and the liabilities assumed are recognized at their fair value, except: - Deferred tax assets or liabilities and liabilities or assets related to employee benefit arrangements, which are recognized and measured in accordance with IAS 12, Income Taxes, Employee Benefits, - Assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5, Non- Assets Held for Sale and Discontinued Operations, Any excess of the cost of acquisition for the Group’s interest in the net fair value of the identifiable assets, liabilities and contingent liabilities of the associated company recognized at the date of acquisition is recognized as goodwill. Goodwill is included in the carrying amount of the investment and is assessed for impairment annually. Any excess of the Group’s interest in the net fair value of the assets, liabilities and contingent liabilities over the cost of acquisition, after the reassessment, is immediately recognized in profit and loss. When the consideration transferred by the Company in a business combination includes assets or liabilities resulting from a contingent consideration arrangement, the contingent consideration is measured at its acquisition-date fair value and later adjustments to the consideration are recognized against goodwill, providing that it has arisen from reliable information on the fair value at the acquisition date and occur during the ‘measurement period’ (which cannot exceed one year from the acquisition date). All other subsequent adjustments are recognized in profit or loss. The subsequent accounting for changes in the fair value of the contingent estimates that do not qualify as measurement period adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not remeasured at subsequent reporting dates. Contingencies classified as assets or liabilities are remeasured at subsequent reporting dates in accordance with IAS 37, Provisions, Contingent Liabilities and Contingent Assets When a business combination is achieved in stages, the Company’s previously held equity interest in the acquiree are remeasured to fair value at the acquisition date (i.e. the date when the Company obtains control) and the resulting gain or loss, if any, is recognized in profit or loss. Amounts arising from interests in the acquiree prior to the acquisition date that have been previously recognized in other comprehensive income (loss) are reclassified to profit or loss where such treatment would be appropriate if that interest were disposed of. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized at that date. c. Cash and cash equivalents and temporary investments – Temporary investments in equity instruments are measured at the fair value prevailing at the date of the financial statements. Subsequent changes in the fair value are recognized in profit or loss. d. Allowances for doubtful accounts – e. Inventories and cost of sales – The Company classifies raw material inventory in the Consolidated Statements of Financial Position based on its expected consumption period, presenting as long-term inventories those which in accordance with historical data and production trends will not be consumed in the short-term (one year). The Company classifies as long-term inventory certain parts and rollers that, according to historical data and trends, showing that such inventories will not be consumed in the short-term. The Company utilizes coke, a form of coal, as a raw material input to fuel its blast furnace which has been inactive in Lorain, Ohio USA plant (see Note 9). The Company has 136,541 metric tons (MT) of coke inventory valued at 1,304 million Mexican pesos (average of USD$ 465.5/MT) on hand at December 31, 2021 and 136,541 MT of coke inventory valued at 953 million Mexican pesos (average of USD$ 350/MT) on hand at December 31, 2020 that is classified as long-term in the accompanying Consolidated Statements of Financial Position. The Company follows the practice of providing a reserve for slow-moving inventory, considering the total of products and raw materials (including coke) with a turnover above one year, which is recorded in the statement of financial position and against account is the cost of sales. The cost of sales of the Company includes inventory costs, outbound freight charges, purchasing and receiving costs, inspection costs, and warehousing costs in cost of goods sold. Vendor payment incentives are recorded as a reduction to cost of goods sold. f. Property plant and equipment – r An item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on the disposal or retirement of an item of property, plant and equipment is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in profit or loss. The initial estimated useful lives of the Company’s main assets are as follows: Years Buildings 10 to 65 Machinery and equipment 5 to 40 Transportation equipment 4 Furniture, chattels and computer equipment 3 to 10 Repair and maintenance costs that significantly increase productive capacity or extend the useful lives of existing plant and equipment are capitalized. Supplies, comprising of spare parts and consumables for internal use are classified under property, plant and equipment and expensed as incurred in the manufacturing process. All other repair and maintenance costs are expensed as incurred. Capital expenditures for projects that cannot be put into use immediately are included in constructions and machinery in-progress. When constructions and machinery in-progress are completed, they are transferred to depreciable assets. g. Leases – h. Costs for loans – Investment income earned on the temporary investment of specific loans pending their expenditure on qualifying assets is deducted from the costs for loans eligible for capitalization. All other costs for loans are recognized in profit or loss in the period in which they are incurred. i. Intangible assets – Expenditure on research activities is recognized as an expense in the period in which it is incurred. An internally-generated intangible asset arising from development (or from the development phase of an internal project) is recognized if, and only if, all of the following have been demonstrated: - The technical feasibility of completing the intangible asset so that it will be available for use or sale; - The intention to complete the intangible asset and use or sell it; - The ability to use or sell the intangible asset; - How the intangible asset will generate probable future economic benefits; - The availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and - The ability to measure reliably the expenditure attributable to the intangible asset during its development. The amount initially recognized for internally-generated intangible assets is the sum of the expenditure incurred from the date when the intangible asset first meets the recognition criteria listed above. Where no internally-generated intangible asset can be recognized, development expenditure is recognized in profit or loss in the period in which it is incurred. Subsequent to initial recognition, internally-generated intangible assets are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately. Intangible assets acquired in a business combination and recognized separately from goodwill are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Subsequent to initial recognition, intangible assets acquired in a business combination are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately. An intangible asset is derecognized on disposal, or when no future economic benefits are expected from use or disposal. Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in profit or loss. j. Goodwill – k. Impairment of tangible and intangible assets other than goodwill – An impairment loss is recognized immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease. Where an impairment loss subsequently reverses, the carrying amount of the asset (or a cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. For purposes of allocation of goodwill when there is business combination will be distributed among each of the cash generating units of the acquiring entity, expected synergy benefits. A reversal of an impairment loss is recognized immediately in profit or loss and allocated to the assets of that unit, the carrying amount of an asset other than goodwill attributable to a reversal of an impairment loss of value shall not exceed the carrying amount that would have been obtained if had not recognized an impairment loss in value for the asset in prior periods. Unless the related asset is recognized at a revalued amount, in which case the reversal of the impairment loss is treated as a revaluation increase. The reversal of the impairment loss is recorded on profit and loss, unless the corresponding asset recognizes a restated amount, in which case the reversal of the impairment loss is treated as a restatement increase. l. Provisions The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the balance sheet date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, it´s carrying amount is the present value of those cash flows. m. Employee benefits – The retirement benefit liability is determined based on the present value of the defined benefit obligation at the date of the statement of financial position. Any compensation included in the determination of the liability premiums corresponds to seniority premiums for retirement. Actuarial gains and losses are recognized on profit or loss for the year. The retirement benefit liability and the related net cost of the period are determined under the projected unit credit method based on projected salaries and certain assumptions determined by independent actuaries. Liabilities for employee benefits recognized in the consolidated statement of financial position represent the present value of the defined benefit obligation. Republic operates various employee benefit plans. The contributions to these benefit plans are either contractually determined by the terms of a collective bargaining agreement with the United Steelworkers or they are under the terms of a defined contribution plan. Accordingly, the company pays fixed contributions to separate entities and they are expensed in the period in which the employees rendered the services entitling them to the benefits. n. Earnings per share – o. Income taxes – - Current tax - Deferred tax The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced by a valuation allowance to the extent that it is no longer probable that sufficient taxable earnings will be available to allow all or part of the asset to be recovered. Deferred tax assets and liabilities are computed using the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the balance sheet date. The effects of changes in the statutory rates are accounted for in the period that includes the enactment date. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Company expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends to settle its current tax assets and liabilities on a net basis. The Company follows the practice of recognizing the benefit from the amortization of acquired or generated tax losses in current earnings that are amortized. - Current and deferred tax for the period - Interests on recoverable tax balances p. Foreign currencies – Exchange differences are recognized in profit or loss in the period in which they arise except for: - Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the cost of those assets and are recorded as an adjustment to interest costs on those foreign currency borrowings; - Exchange differences on transactions entered into in order to hedge certain foreign currency risks; and - Exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither planned nor likely to occur (therefore forming part of the net investment in the foreign operation), which are recognized initially in other comprehensive income and reclassified from equity to profit or loss on sale of all or part of the net investment. q. Financial instruments – Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at fair value through profit or loss are recognized immediately in profit or loss. r. Financial assets – The effective interest method is a method of calculating the amortized cost of a debt instrument and of allocating interest income over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash receipts (including all fees and points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the debt instrument, or, (where appropriate), a shorter period, to the net carrying amount on initial recognition. The Company does not have financial assets classified as “available-for-sale financial assets”. Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and accounts receivable are measured at amortized cost using the effective interest method, less any impairment. Financial assets are assessed for indicators of impairment at the end of each reporting period. Financial assets are considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of the investment have been affected. Objective evidence of impairment could include: - Significant financial difficulty of the issuer or counterparty; - Breach of contract, such as a default or delinquency in interest or principal payments; - It becoming probable that the borrower will enter bankruptcy or financial re-organization; or - The disappearance of an active market for that financial asset because of financial difficulties. For certain categories of financial assets, such as trade receivables, assets that are assessed not to be impaired individually are, in addition, assessed for impairment on a collective basis. Objective evidence of impairment for a portfolio of receivables could include the Company’s past experience of collecting payments, as well as observable changes in national or local economic conditions that correlate with default on receivables. For financial assets carried at amortized cost, the amount of the impairment loss recognized is the difference between the asset’s carrying amount and the present value of estimated future cash flows, discounted at the financial asset’s original effective interest rate. The carrying amount of the financial asset is reduced by the impairment loss directly for all financial assets with the exception of trade receivables, where the carrying amount is reduced through the use of an allowance account. When a trade receivable is considered uncollectible, it is written off against the allowance account. Subsequent recoveries of amounts previously written off are credited against the allowance account. Changes in the carrying amount of the allowance account are recognized in profit or loss. Except for equity instruments available for sale, if, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss is reversed through profit or loss to the extent that the carrying amount of the investment at the date the impairment is reversed does not exceed what the amortized cost would have been had the impairment not been recognized. The Company recognizes a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another entity. If the Company neither transfers nor retains substantially all the risks and rewards of ownership and continues to control the transferred asset, the Company recognizes its retained interest in the asset and an associated liability for amounts it may have to pay. If the Company retains substantially all the risks and rewards of ownership of a transferred financial asset, the Company continues to recognize the financial asset and also recognizes a collateralized borrowing for the proceeds received. On recognition totally a financial asset, the difference between the carrying amount of an asset and the sum of the consideration received and receivable and the cumulative gain or loss that had been recognized in other comprehensive income and accumulated in equity is recognized in profit or loss. When the financial asset is partially derecognized (when the Company retains the option to repurchase part of a transferred asset, or retains residual interest that does not result in the retention of substantial risks and rewards of ownership and the Company retains control), the Company will distribute the initial value of the financial asset between the part that continues to be recognized and the part that is no longer recognized based on the fair values ​​of various parts as of the transfer date. The difference between the book value assigned to the part that is no longer recognized and the sum of the consideration received by such part; and any accumulated profit or loss assigned to it that has been recognized in other comprehensive income will be recognized in the consolidated income statement. s. Financial liabilities – Financial liability at fair value with changes through profit or loss is a financial liability classified as held for trading or it is designated as at fair value with changes through profit or loss. A financial liability is classified as held for trading if: - It has been acquired principally for the purpose of repurchasing it in the near term; - On initial recognition, it is part of a portfolio of identified financial instruments that the Company manages together and has a recent actual pattern of short-term profit-taking; or - It is a derivative that has not been designated as a hedging instrument and fulfils the condition to be effective. A financial liability other than a financial liability held for trading may be designated as at fair value through profit or loss upon initial recognition if: - Such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise; or - The yield of a group of financial assets, financial liabilities or both, is administered and assessed based on its fair value, according to an investment strategy or risk management that the Company has documented and provided internal information over that group, based on its fair value; or - The financial liability forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair value basis, in accordance with the Company’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or - It forms part of a contract containing one or more embedded derivatives, and IAS 39, Financial Instruments: Recognition and Measurement, - Financial liabilities at fair value through profit or loss are recorded at fair value, with any gains or losses arising on remeasurement recognized in profit or loss. The net gain or loss recognized in profit or loss incorporates any interest paid on the financial liability and is included in the ‘other gains and losses’ line item in the consolidated statement of comprehensive income. - Other financial liabilities including borrowings are subsequently measured at amortized cost using the effective interest method. The effective interest method is a method of calculating the amortized cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the expected life of the financial liability, or (where appropriate a shorter period), to the net carrying amount on initial recognition. - The Company derecognizes financial liabilities when, and only when, the Company’s obligations are discharged, cancelled or expire. The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable is recognized in profit or loss at that time. t. Derivative financial instruments – These derivatives are initially recognized at fair value at the date the derivative contracts are entered into and subsequently are remeasured to the fair value at the end of reporting period. The resulting gain or loss is recognized in profit or loss immediately unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship. To mitigate the risks associated with changes in natural gas prices occurring naturally as a result of the supply and demand on international markets, the Company uses natural gas cash-flow exchange contracts or natural gas swaps to offset fluctuations in the price of natural gas, whereby the Company receives a floating price and pays a fixed price. Fluctuations in natural gas prices from volumes consumed are recognized as part of the Company’s operating cost. At the inception of the hedge relationship, the Company documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Company documents whether the hedging instrument is highly effective in offsetting exposure to changes in fair values or cash flows of the hedged item attributable to the hedged risk. The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income and accumulated under the heading of fair value of derivative financial instruments, The Company periodically evaluates the changes in cash flows of the derivative instrument to analyze if the swaps are highly effective for mitigating the exposure to natural gas price fluctuations. A hedge instrument is considered to be highly effective when changes in its fair value or cash flows of the primary position are compensated on a regular or cumulatively basis, by changes in fair value or cash flows of the hedging instrument in a range between 80% and 125%. Amounts previously recognized in other comprehensive income are reclassified to profit or loss in the periods when the hedged item is recognized in profit or loss, in the same line of the consolidated statement of comprehensive income as the recognized hedged item. However, when the hedged forecasted transaction results in the recognition of a non-financial asset or a non-financial liability, the ga

Critical accounting judgments and key sources of estimates	5. Critical accounting judgments and key sources of estimates In the application of the Company’s accounting policies, which are described in Note 4, management is required to make judgments, estimates and assumptions regarding the carrying amounts of assets and liabilities. The estimates and associated assumptions are based on historical experience, the future and other factors that are considered to be relevant. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an ongoing basis and the resulting changes are recorded on the period in which the estimate has been modified, if such change affects only that period or in future periods. a. Critical accounting judgments – The following are the critical judgments in the application of accounting policies, apart from those involving estimations, that the management have made in the process of applying the Company’s accounting policies and that have the most significant effect on the amounts recognized in the financial statements: - Functional currency – b. Key information for estimates – The following are the key assumptions, and other key sources of estimation at the consolidated balance sheet date, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the following financial year. - Allowance for doubtful accounts - Net realizable value of inventory - Impairment of long-lived assets in use - Estimating useful lives and residual values of property, plant and equipment - Impairment of goodwill – - Employee Benefits A change in the economic, employment and fiscal conditions could modify the estimates. - Contingencies – - Deferred income tax assets – - Valuation of financial instruments – The Company’s management believes that the chosen valuation techniques and assumptions used are appropriate in determining the fair value of derivative financial instruments. At December 31, 2021 and 2020 the Company has no derivative financial instruments.

Trade receivables – Net [Abstract]
Trade receivables – Net	7. Trade receivables – Net The average collection period on sales of goods is between 30 and 60 days. No interest is charged on the outstanding accounts receivables from clients. The Company has recognized an allowance for doubtful accounts to show the possible financial loss caused by the inability of customers to make the corresponding payments. Allowances for doubtful accounts are calculated based on several factors including price adjustments, likelihood of recovery, aging and historical experience. Credit limits and credit scores of customers are reviewed twice a year. On December 31, 2021 and 2020 there were no customers who represent more than 5% of the total balance of trade receivables. The Company does not hold any collateral or other credit enhancements over these balances nor does it have a legal right of offset against any amounts owed by the Company to the counterparty. Trade receivables disclosed below include amounts that are past due at the end of the reporting period for which the Company has not recognized an allowance for doubtful debts because there has not been a significant change in credit quality and the amounts are still considered recoverable. The Company does not hold any collateral. In general terms, the accounts receivable does not show impairment. Age of net receivables that are past due were as follows: At December 31, 2021 2020 30 - 60 days $ 355,633 $ 164,646 61 - 90 days 62,387 22,288 91 + days 93,504 245,420 Total $ 511,524 $ 432,354 During the years ended December 31, 2021 and 2020, the movement in the allowance for doubtful accounts was as follows: 2021 2020 Balance at beginning of year $ 233,355 $ 237,098 Provisions 22,247 Cancellation (415 ) Account recoveries (2,708 ) (1,333 ) Translations effects (28,325 ) (1,995 ) Balance at end of year $ 224,569 $ 233,355 The Company recognize an estimation for expected credit loss, based on the historical experience of credit losses in their accounts receivable, current conditions and reasonable and sustainable forecasts of the different quantifiable future events that could affect the amount of future cash flows for recovering accounts receivable. In determining the non-recoverable portion of accounts receivable, the Company considers any change in the credit quality of the trade receivable from the date credit was initially granted up to the end of the reporting period. The concentration of credit risk is minimum, due to the fact that the customer base is large and unrelated.

The locality of this steel mill was selected due to its strategic location close to customers and the availability of skilled labor. Furnace construction started at midyear of 2012 and the operations started production in July 2014. The furnace steel amount includes of USD $ 45.4 million of labor and capitalized indirect expenses. This facility was idled in June of 2015 and management has no near-term plans to restart the facility, except for the Lorain 9/10” Mill, which is in the process of being recommissioned due to market demand for cold heading quality steel (CHQ) and special bar quality steel (SBQ). The expectation is that it will be restarted when market conditions improve substantially, particularly in the oil and gas drilling industry. During 2021 and 2020 the Company invested in certain improvements in the Lorain facility so as to be better prepared to reactivate the plant, with USD$ 15.6 and USD$ 6.0 million recorded to construction-in-progress for the years ended December 31, 2021 and 2020, respectively. The Company has property, machinery, and equipment with a net book value of approximately USD$ 54.6, USD $ 40.3 As a consequence of this event, management determined a triggering event took place to where the long-lived assets at the Lorain facility may not be fully recoverable. Management performed an analysis of the fair value of the Lorain facility with the assistance of an independent valuation firm and determined the net book value exceeded the fair value by approximately U.S.$130.7 million (Ps.$ 2,701 million) and as such recognized an asset impairment of this amount during the year ended December 31, 2015. The fair value determination at the Lorain facility was based on an independent valuation of the Lorain melt shop assets using the comparable match method of the market approach. The income approach was not considered an appropriate fair value measurement due to the absence of reliable forecast data as the facility was idled indefinitely in early 2016. Management further assessed if there were any impairments at the Company’s other asset groups in accordance with IFRS and determined that as of December 31, 2021, no other asset groups were impaired based on current projections. No further impairment was considered necessary or appropriate.

Such benefit plans to employees are described below: a. Collective Bargaining Agreements As of December 31, 2021, 2020 and 2019 76%, 70% and 79%, respectively of Republic employees are covered by a collective bargaining agreement (labor agreement) with the United Steelworkers (“USW”). The agreement initially expired on August 15, 2016, was extended for three years through August 15, 2019, and further extended through August 15, 2022. The extended agreement renews all the provisions, understandings and agreements set forth in the January 1, 2012 Basic Labor Agreement. The base rates of pay determined under the extended agreement will remain unchanged from those ruling under the expired agreement as of August 16, 2016. The extended agreement provides that Company’s quarterly contributions to fund the Republic Retirement VEBA Benefit Trust (the “Benefit Trust”) be reduced from $2.6 million to $0.25 million beginning in August 15, 2016 through June 30, 2019. Effective July 1, 2019, the Company’s contribution to the Benefit Trust changed to $4.00 per hour for each hour worked by USW represented employees. Effective August 16, 2019, until June 30, 2022, the Company obligation to finance the Profit Trust changed again and is limited to the creation of a profit-sharing pool consisting of 3% of the quarterly profits from $ 0 to 50 million and 4% of the profits of the Company over % 50 million. Effective July 1, 2022, the Company’s contribution to the Beneficiary Trust changes back to a limit of $ 4.00 per hour worked by USW represented employees. b. Defined Contribution Plans Plan for employees- Participation in a multi-employer pension plan agreed under terms of a collective bargaining agreement differs from a traditional qualified single employer defined benefit pension plan. The SPT shares risks associated with the plan in the following respects: I. Contributions to the SPT by Republic may be used to provide benefits to employees of other participating employers; II. If a participating employer stops contributing to the SPT, the unfunded obligations of the plan may be borne by the remaining participating employers; and III. If Republic chooses to stop participating in the SPT, Republic may be obliged to pay an amount based on the underfunded status of the plan, referred to as a withdrawal liability. c. VEBA Benefit Trust The Company is required to make quarterly contributions to the defined contribution plan for post-retirement health benefits VEBA as determined by the terms of the USW collective bargaining agreement. The Benefit Trust is a health and welfare plan for USW retiree benefits, and is not a “qualified” plan under the regulations of the Employee Retirement Income Security Act of 1974. For the years ended December 31, 2021, 2020 and 2019, the Company recorded expenses of USD $ 0.5, USD $ 0 million and USD $ 1.1 million, respectively, related to this benefits plan.

This plan is designed to provide retirement benefits through Company contributions and voluntary deferrals of employees’ compensation. The Company funds contributions to this plan each pay period, based on the participant’s age and years of service as of January first of each year. The amount of the Company contribution is equal to the monthly base salary multiplied by the appropriate percentage based on age and years of service. The contribution becomes 100% vested upon completion of three years of vesting service. In addition, employees are permitted to make contributions to this 401(k)-retirement plan through payroll deferrals. In this case, the Company provides a 25.0% matching contribution for the first 5.0% of payroll that an employee elects to contribute. Employees are 100% vested in both their and Republic matching 401(k) contributions. For the years ended December 31, 2021, 2020 and 2019 the Company recorded expense of USD $ 1.0 Employees who are covered by the USW labor agreement are eligible to participate in the 401(k) defined contribution retirement plan through voluntary deferrals of employees’ compensation. There are no Company contributions or employer matching contributions relating to these employees. e. Profit Sharing and Incentive Compensation Plans The labor agreement includes a profit sharing plan to which the Company is required to contribute The extended agreement modified the plan to the following quarterly pretax income, as defined in the labor agreement (“EBT”): 3% of EBT between $0 and $25 million per quarter; 4% of EBT between $25 and $75 million per quarter; and 5% of EBT over $75 million per quarter. For the year ended December 2020 and 2019, the company does not make outlays, because the current year thresholds had not been achieved, USD $ 0.5 million of expense was recorded for the year ended December 31, 2021. Republic has a profit-sharing plan for all salaried employees and nonunion workers. The profit-sharing plan was based on achieving certain profitability, inventory and shipments targets. In the year ended December 31, 2021, 2020 and 2019 the Company paid USD 0.5 million, USD $ 0.0 and USD $0.0 million respectively, under this plan.

Contingencies Disclosure [Abstract]
Contingencies	23. Contingencies As of December 31, 2021, the Company has the following contingencies: a. Pacific Steel, Inc. (PS), a subsidiary located in National City in San Diego County, California, United States of America, for which the main activity is the purchase and sale of scrap, has the following environmental contingencies: California Department of Toxic Substances Control On September 2002, the Department of Toxic Substances Control (DTSC) inspected PS facilities based on an alleged complaint from neighbors due to PS’s excavating to recover scrap metal on its property and on a neighboring property, which PS rents from a third party (BNSF Railway). In this same month, DTSC issued an enforcement order of imminent and substantial endangerment determination, which alleges that certain soil piles, soil management and metal recovery operations may cause an imminent and substantial danger to human health and the environment; consequently, DTSC sanctioned PS for violating Hazardous Waste Control Laws in the State of California and imposed the obligation to remedy the site. On July 26, 2004, in an effort to continue with this order, DTSC filed against PS a Complaint for Civil Penalties and Injunctive Relief in San Diego Superior Court. On July 26, 2004, the court issued a judgment, whereby PS was obligated to pay USD$ 0.2 million, which has been paid. On June 6, 2010, the DTSC and the San Diego Department of Environmental Health (DEH) inspected the facilities of PS, in response to a general complaint. On August 10, 2010 DTSC and DEH conducted a second inspection and found seven infractions. The DEH is satisfied with the compliance of PS on those issues; however, on October 19, 2010 the technical division of the DTSC recommended to the legal division of DTSC that it impose significant penalties. The land remediation was suspended at the beginning of 2011 due to the inefficiency of the process, which was verified by several studies. As an alternative, once the necessary permits were obtained from the authorities in Mexico, the Mexicali plant began the process of importing non-RCRA soil for final disposal in a secure landfill based in Nuevo Leon State. This landfill is deposited after the separation of the metal content, which is used as raw material in the melting process. PS has completed the shipment of non-RCRA soil for final disposal in Nuevo Leon State. The disposition of a stack estimated at 8,000 tons of material classified RCRA (hazardous for Federal purposes) was also considered for shipment to Mexico. The process began in early 2013, but the response from the authorities was slow. Therefore, on April 9, 2015, a letter from the California Attorney General Department of Justice (Attorney General) was received where PS is required to, in the absence of obtaining permission from the Mexican authorities; present a program for transport the pile of contaminated soil classified as RCRA to an authorized confinement in the United States at the latest on April 22, 2015. This letter warned that PS must ship the RCRA soil no later than July 9, 2015, or risk DTSC proceeding with a civil lawsuit seeking the maximum amount of fines established by law and corresponding legal redress. On April 21, 2015, PS sent a letter to the Attorney General explaining that the authorities in Mexico had not denied permission to the Company but had simply requested that it present its application in a different format, which had already been presented and reviewed by the authority on April 17, 2015. On July 23, 2015, the Attorney General denied the extension requested by PS and demanded the immediate shipments of the RCRA stack to an authorized landfill. PS began transporting RCRA soil on July, 29, 2015, and completed removal of the RCRA stack by September 12, 2015 with a total of 3,000 metric tons. On January 5, 2016, the Attorney General and PS stipulated to filing a “final judgment and order on consent” or Consent Judgment in San Diego Superior Court. The parties negotiated the Consent Judgment, which includes the following terms: - PS to pay USD$ 0.138 million as a civil penalty for alleged violations of the 2004 Corrective Action Consent Agreement. PS has made all of the required payments to DTSC as of December 31, 2017. - Remove the RCRA soil pile and send it to an approved landfill. The Judgment indicates that the Company complied with this commitment by October 2, 2015. - After eliminating the soil pile of RCRA, the Company should take samples of the floor in which it was located. Samples were taken and the results indicate that the floor had pollution levels that exceeded the limits established by Government. In April 7, 2016, the General Prosecutor and the DTSC required that the Company would turn over the floor ten feet wide and two feet down in the perimeter of the area in which was located the soil pile RCRA and to dispose it in an approved confinement. In turn, PS convinced to DTSC to reach a Turnpike Agreement at august 10, for which would be paid during two years (up to August 10, 2018). The Agreement was extended, as of August 10, 2018, for a two years additional period, in force up to August 10, 2020. These Agreement had another extension, in force up to August 10, 2021. And has not been renewed. - The Company shall continue to meet the conditions of the final judgment, the corrective measures, and all tasks arising from this, which were entered in the same court in 2004. On May 29, 2019, the company submitted a proposal with a new work plan (IM Work Plan) to DTSC to conduct soil remediation on the BNSF Railway lease. On October 21, 2021, The Company submitted the final draft of the IM work plan which DTSC has agreed to that proposal or work plan, although final approval has not been granted. In September 2020, PS informed the DTSC that it had been significantly affected by the COVID pandemic and the corresponding economic downturn, although it was still committed to the application of a work plan from IM, it required implementation efforts to be put on hold. Such deployment is in hold as of this date. Before the Company could implement the Interim Measures Workplan, DTSC must undergo a public review process and provide final approval. DTSC began this process on or about January 19, 2022, by publishing a community survey in the area around the Company’s site and initiating the tribal consultation process to determine if any Native American tribes with affiliation to the area would be interested in participating in the public review process. It is unclear at this point if DTSC will give final approval or when such approval may occur. At this time, we cannot estimate the cost of implementing the Interim Measures Workplan given the uncertainty regarding whether DTSC will approve it and when such approval may be granted. b. As with most steel producers in United States of America, Republic could incur significant costs related to environmental issues in the future, including those arising from environmental compliance activities and remediation stemming from historical waste management practices at the Republic’s facilities. The reserve created to cover probable environmental liabilities of USD$ 2.5 million, USD$ 2.5 million and USD$ 2.6 million were recorded as of December 31, 2021, 2020 and 2019, respectively. The reserve includes incremental direct costs of remediation efforts and post-remediation monitoring costs that are expected to be paid after corrective actions are complete. As of December 31, 2021, 2020 and 2019, the current and non-current portions of the reserve amounted to USD$ 1.0 million and USD $ 1.5 c. The Company is not aware of any material environmental remediation liabilities or contingent liabilities relating to environmental matters with respect to facilities, for which the establishment of an additional reserve would be necessary at this time. In the event that, in the future, the Company incurs in any such additional expenses, these costs will most likely be incurred over a number of years. However, future regulatory action regarding historical waste management practice in the facilities of Republic PS and future changes in applicable laws and regulations may require the Company to incur significant costs that may have a material adverse effect on the future financial performance of the Company. d. The Company is involved in a series of lawsuits and legal claims that have arisen during the normal course of its operations. The Company and its legal advisors do not expect the outcome of these matters to have any significant adverse effect on the Company’s financial position and results of operations, therefore it has not been recognized any liabilities for such lawsuits and claims. e. Mexican tax authorities have the right to review, at least the previous five years and could determine differences in taxes payable, plus any corresponding adjustments, surcharges and fines. f. Tax authorities in the United States of America have the right to review, at least the previous three years and could determine differences in taxes payable, plus its corresponding adjustments, surcharges and fines. g. Canadian tax authorities have the right to review, at least the previous four years and could determine differences in taxes payable, plus its corresponding adjustments, surcharges and fines. h. Brazilian tax authorities have the right to review, at least the previous five years and could determine differences in taxes payable, plus its corresponding adjustments, surcharges and fines. i. On September 5, 2017, Grupo Simec and GV do Brasil were notified of the arbitration procedure filed by SMS Concast at the International Court of Arbitration (ICC), which demands the payment of USD $ 1.4 million plus expenses, for additional costs incurred in the construction and assembly of the steelmaking area of the Brazilian plant. On November 6, 2017, the companies of the Group replied to the demand and filed a counterclaim against SMS Concast for the amount of USD $ 5 million, which GV do Brasil utilized on the equipment to work properly. On February 26, 2020, The company was notified of the judgment. In March 2021, it was agreed with the actor to conclude the matter by paying USD $ 450 thousand dollars, after several changes of dates, the payment was made on July 8, 2021. j. During the 2020 and 2019 financial year, some of the Simec Group subsidiaries that have oversight acts affected tax payments and expenses through Remedial Agreements signed between the companies and the Tax Administration Service (SAT) during the aforementioned years for an amount of $554.4 million and $2,323.7 million. All lawsuits regarding the tax credits were settled, as of the date of signing this document, the release process continues. k. Related to Republic Steel’s audits of GST for the periods 2015-2016 and 2017-2018 made by the Canadian Revenue Agency (CRA), amounts of USD $4,178,517 plus interest for the period 2015-2016 and USD $6,372,306 plus interest for the period 2017-2018 were determined by the CRA. The Company presented a notice of objection for the 2015-2016 period on September 2018 and another for the 2017-2018 period on March 2021. This matter was settled during the year ended December 31, 2021. l. In connection with a sale and use tax audit by the Ohio Department of Taxes covering the period from January 1, 2009 to December 31, 2012, an assessment of $ 2,452,028 (including interests of $ 394,138) against the Company was issued, on December 9, 2016. The Company does not agree with the evaluation in its entirety and has filed a Reevaluation Petition on January 30, 2017 appealing the assessment to the Ohio Board of Tax Appeals. As of May 27, 2020, no resolution has been obtained on this appeal. The Company also received a notification of appraisal at December 11, 2020, for $1,631,827 (including interest for $339,885, which covers the period from January 1st, 2014 to September 30, 2018, The Company neither agreed with the appraisal in its whole, for the same reasons and it has presented an appeal before the Board of Tax Appeals of Ohio.

Commitments	24. Commitments a. On May 1, 2018, the Company signed a contract with ArcelorMittal S.A. in Brazil, for the acquisition of Cariacica and Itauna steels for rent, producing plants and wire drawing equipment for the production of wires and derivatives. The Cariacica unit has the capacity to produce 600 thousand metric tons of liquid steel per year and 450 thousand metric tons of rolled steel products. This plant has in 2021 and 2020 more than 800 and 500 employees in 2019, and can produce rod and light structural profiles. The factory is located in the city of Cariacica, next to the city of Victoria, in the state of Espírito Santo on a land of more than 1,200,000 square meters. The Itauna unit has an installed capacity to produce 120 thousand metric tons per year of steel laminate products and can manufacture light structural profiles and rods. The plant is located in the city of Itauna in the state of Minas Gerais, less than 100 kilometers away from Belo Horizonte and in 2021, 2020 and 2019 has 145,114 and 94 employees, respectively. The factory was leased under a contract expiring in August 2020. After its expiration, the plant was acquired. b. Republic leases certain equipment, office space and computer equipment under non-cancelable operating leases. The leases expire at various dates through 2020. During the years ended December 31, 2021, 2020 and 2019, rental expenses relating to operating leases amounted to USD$ 0.0, USD $ 0.1 $ 0.7 c. In January 2013, The Company reached a contract with EnerNOC, which allows Republic to receive payments for reduction in the electric energy consumption during a term declared by PJM Interconnection as an Emergency. The contract is for 5 years starting at January 31, 2013 and concluded at May 31, 2018. At that date, the Agreement was extended up to May 31, 2021.In January 2021, the company entered into a similar agreement with NRG Curtailment Solutions, Inc. with a term of five years. The Company recognized an income for both contracts in 2021, 2020 and 2019 for USD $ 1.2 million, USD$ 1.1 million and USD $ 1.8 million, respectively. d. In January 2018, the Company entered into a contract with the supplier ECOM, LTDA. for an amount of USD $ 6.3 million for the purchase of energy of 10,000 MWH per month, for its subsidiary GV do Brasil Industria y Comercio de Aço LTDA, starting the supply in 2019. All payments with monthly maturity are made 6 days after the month end closing. The contract ended in February 2020. e. On February 22, 2018, the contract was signed with Primental Technologies of Italy, United States of America and Mexico, for the construction of the Lamination train and the supply of a new reheating furnace for the Mexicali plant, thereby increasing capacity manufacturing for the manufacture of finished product from 17,500 to 22,500 tons per month. From January 2021, flat bars are being produced. As of today, some adjustments are being made to start the production of rebar in May 2021, and light structures in June 2021. Naturally, the COVID pandemic delayed significantly the process. USD $24 million from budget has already been spent. f. In order to maintain and increase the continuity and quality of the electricity supply in all the Group’s plants, the scheme change from Basic Supply (SSB) to the Qualified Supply Service (SSC), with the provision of acquiring energy in the wholesale electricity market. With the implementation of this project, which only requires the modernization of the set of equipment that records the consumption measurements of the electrical substations of each plant, it seeks to achieve a more efficient, safe, clean and transparent electrical service and more competitive prices than those current. The cost of this project as of October is USD$1 million 415 thousand, and the only thing missing is the installation in Mexicali due to the lack of conditions in the wholesale electricity market. g. In the program execution to remedy the breach of the requirement to keep placed between the investing public of at least 12% of the shares representing the Capital Stock of our issuer, presented to the Market Surveillance Directorate of the Bolsa Mexicana de Valores, S.A. de C.V., on August 27, 2019, the placing of sufficient shares on the markets to exceed that minimum percentage of shareholding is in process. h. On December 20, 2020, we purchased the Itauna plant by Cia. Siderúrgica de Espirito Santo, S.A. to Compañia Itaunense Energia y Participacoes Inmueble y Equipo Inmueble, located on Rua Clara Chaves at villa Santa Maria, Itauna city, committing to pay R$ 4.0 million reais per month, up to a total value of R$ 105.0 million reais, such payments have to be made until 2022.

Subsequent events	25. Subsequent events Our company actively conducts ongoing reviews of our commercial practices in Mexico and other countries to avoid, as much as possible, the imposition of tariff rates on our products. On January 16, 2020, a preliminary tariff of 6.75% was imposed on our corrugated rod exports to the United States of America. After the review from their Department of Commerce (DOC), the tariff was reduced to 1.46%. after the review from the Department of Commerce (DOC), the Company did not participate in the period of November 1, 2018 to October 31, 2019, The dumping rate that was established was 4.93% published in September 2021 for which the company made a payment of USD $ 189 thousand dollars on March 30, 2022. On January 6, 2021, the dumping review process began for the period from November 1, 2019 to October 31, 2020. On November 30, 2021, the DOC published a preliminary dumping rate for the Company of 66.70% arguing and/or justifying deficiencies in the information, the Company decided to appeal this result. The appeal is in process. Risks Related to Global Economic Conditions The outbreak of COVID-19 and disruptions in the steel industry have had, and are expected to continue to have, an adverse effect on our results of operations, financial condition and cash flows. The ongoing global pandemic resulting from the spread of COVID-19 has had a significant effect on economies, businesses and individuals around the world. Efforts by governments around the world, including in the U.S. and Mexico, to contain COVID-19 have involved, among other things, border closings and other significant travel restrictions; mandatory stay-at-home and work-from-home orders; mandatory business closures; public gathering limitations; and prolonged quarantines. These efforts and other governmental, business and individual responses to the COVID-19 pandemic have led to significant disruptions to commerce, supply chains, credit losses, lower consumer demand for goods and services and general uncertainty regarding the near-term and long-term effects of COVID-19 on the domestic and international economy and on public health. Global steel production has been and will continue to be affected by volatility in the market due to the ongoing COVID-19 pandemic and uncertainty remains around the extent and duration of the pandemic, the emergence of new and more contagious variants of the virus and the effectiveness of vaccine programs. We expect steel consumption in the automotive and construction industries to be lower due to delays and reduced demand for steel products in North America and globally. These developments and other consequences of the COVID-19 outbreak have and could continue to materially adversely affect our results of operations, financial condition and cash flows. The ongoing COVID-19 pandemic could negatively affect our internal controls over financial reporting as a portion of our workforce continues to be required to work from home and, therefore, new processes, procedures, and controls could be required to respond to changes in our business environment. In addition, the COVID-19 outbreak continues to significantly increase economic and demand uncertainty. The current outbreak and continued spread of COVID-19 and the emergence of new and more contagious variants could cause a global recession, which would have a further material adverse effect on our results of operations, financial condition and cash flows. Global activity levels started to improve during the second half of 2020; however, the full extent to which the COVID-19 outbreak will affect our operations, and the steel industry generally, remains highly uncertain, differs from country to country and will ultimately depend on future developments which cannot be predicted at this time, including the duration and scope of the restrictions put in place in different locations to reduce the rate of infections and hospitalizations, the development and spread of variants of COVID-19 and the effectiveness of vaccines as new variants of COVID-19 appear and spread, levels of unemployment, the length of time required for demand to return and normal economic and operating conditions to resume. While some restrictions were lifted in the second and third quarters of 2020, new restrictions were implemented in the fourth quarter of 2020 due to second wave and new restrictions were implemented in the first part and last quarter of 2021. We cannot predict whether restrictions will be further relaxed, reinstated or made more stringent. The effects of the COVID-19 pandemic may also have the effect of exacerbating many of the other risks faced the company. Global economic conditions, such as the financial crisis and economic recession relating to the COVID-19 pandemic and the Russian invasion of Ukraine have in the past, and may continue to, significantly impact our business. The corresponding reduction in demand across the economy in general and in the automotive, construction and manufacturing sectors due to the global pandemic has reduced demand for steel products in North America and globally. These economic conditions significantly impacted, and will continue to significantly impact, our business and results of operations. Although the reasons mentioned before, demand, production levels and prices in certain segments and markets have recovered and stabilized to a certain degree in 2021. On February 24, 2022, Russia invaded Ukraine, which, due to geopolitical reasons, increased the uncertainty and could delayed the global economic recovery. If global macroeconomic conditions deteriorate, the outlook for steel producers would be adversely affected. It is difficult to predict the duration or severity of a new global economic downturn, or to what extent it will affect us. An unsustainable recovery and persistently weak economic conditions in our key markets could depress demand for our products and adversely affect our business and results of operations. We sell our products to the automotive and construction-related industries, both of which reported substantially lower customer demand during and after the latest global recession and have recently exhibited reduced demand for steel products due to the ongoing financial recession. As a result, our operating levels in recent years declined compared to pre-recession levels. In 2017 there was a slight increase in sales to the automotive industry compared to 2016, in 2018 we experienced a slight decrease in our sales to the automotive industry compared to 2017 and in 2020 and 2019 we experienced a decrease in our sales to the automotive industry compared to 2018. Rise on net sales of our SBQ steel of 17% in 2021 compared to 2020. Moreover, if the global economic downturn continues for a prolonged period, or a new global financial crisis occurs, we may face increased risk of insolvency and other credit related issues of our customers and suppliers, as we faced with our customers and suppliers particularly in industries that were hard hit by the latest recession, such as automotive, construction and appliance. Also, there is the possibility that our suppliers face similar risks. The decrease in available credit may increase the risk default of our clients and that our suppliers might delay the raw materials delivery. The impact of global economic conditions on these industries may have a significant effect on our results of operations. Finally, if global economic conditions continue to deteriorate, we may be required to undertake asset impairments, as we have been required to undertake in the past.

Accounting Policies [Abstract]
Conversion of foreign subsidiaries financial statements	a. Conversion of foreign subsidiaries financial statements – The Effects of Changes in Foreign Exchange Rates The U.S. dollar (US Dollar or USD$) was considered as the functional currency of all the U.S. subsidiaries and Brazilian real for subsidiaries established in Brazil; therefore, the financial statements of these subsidiaries abroad were converted to Mexican pesos applying: - The exchange rates at the balance sheet date, to all assets, liabilities and stockholder´s equity. - The historical exchange rate at revenues, costs and expenses. The conversion differences are carried directly to the consolidated statements of comprehensive income as other comprehensive income under the caption translation effects of foreign subsidiaries. Relevant exchange rates used in the conversion of the financial statements of foreign subsidiaries were as follows (Mexican pesos per one U.S. dollar): Current exchange rate as of December 31, 2021 20.52 Current exchange rate as of December 31, 2020 19.95 Average exchange rate for the year ended December 31, 2021 (*) 20.28 Average exchange rate for the year ended December 31, 2020 (*) 21.49 Current exchange rate as of May 17, 2022 20.14 (*) Average exchange rate used to translate revenues, costs and expenses of the companies mentioned above.
Business combinations	b. Business combinations – At the date of acquisition, the identifiable assets acquired and the liabilities assumed are recognized at their fair value, except: - Deferred tax assets or liabilities and liabilities or assets related to employee benefit arrangements, which are recognized and measured in accordance with IAS 12, Income Taxes, Employee Benefits, - Assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5, Non- Assets Held for Sale and Discontinued Operations, Any excess of the cost of acquisition for the Group’s interest in the net fair value of the identifiable assets, liabilities and contingent liabilities of the associated company recognized at the date of acquisition is recognized as goodwill. Goodwill is included in the carrying amount of the investment and is assessed for impairment annually. Any excess of the Group’s interest in the net fair value of the assets, liabilities and contingent liabilities over the cost of acquisition, after the reassessment, is immediately recognized in profit and loss. When the consideration transferred by the Company in a business combination includes assets or liabilities resulting from a contingent consideration arrangement, the contingent consideration is measured at its acquisition-date fair value and later adjustments to the consideration are recognized against goodwill, providing that it has arisen from reliable information on the fair value at the acquisition date and occur during the ‘measurement period’ (which cannot exceed one year from the acquisition date). All other subsequent adjustments are recognized in profit or loss. The subsequent accounting for changes in the fair value of the contingent estimates that do not qualify as measurement period adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not remeasured at subsequent reporting dates. Contingencies classified as assets or liabilities are remeasured at subsequent reporting dates in accordance with IAS 37, Provisions, Contingent Liabilities and Contingent Assets When a business combination is achieved in stages, the Company’s previously held equity interest in the acquiree are remeasured to fair value at the acquisition date (i.e. the date when the Company obtains control) and the resulting gain or loss, if any, is recognized in profit or loss. Amounts arising from interests in the acquiree prior to the acquisition date that have been previously recognized in other comprehensive income (loss) are reclassified to profit or loss where such treatment would be appropriate if that interest were disposed of. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized at that date. c. Cash and cash equivalents and temporary investments – Temporary investments in equity instruments are measured at the fair value prevailing at the date of the financial statements. Subsequent changes in the fair value are recognized in profit or loss. d. Allowances for doubtful accounts – e. Inventories and cost of sales –
Cash and cash equivalents and temporary investments	c. Cash and cash equivalents and temporary investments – Temporary investments in equity instruments are measured at the fair value prevailing at the date of the financial statements. Subsequent changes in the fair value are recognized in profit or loss.
Allowances for doubtful accounts	d. Allowances for doubtful accounts –
Inventories and cost of sales	e. Inventories and cost of sales – The Company classifies raw material inventory in the Consolidated Statements of Financial Position based on its expected consumption period, presenting as long-term inventories those which in accordance with historical data and production trends will not be consumed in the short-term (one year). The Company classifies as long-term inventory certain parts and rollers that, according to historical data and trends, showing that such inventories will not be consumed in the short-term. The Company utilizes coke, a form of coal, as a raw material input to fuel its blast furnace which has been inactive in Lorain, Ohio USA plant (see Note 9). The Company has 136,541 metric tons (MT) of coke inventory valued at 1,304 million Mexican pesos (average of USD$ 465.5/MT) on hand at December 31, 2021 and 136,541 MT of coke inventory valued at 953 million Mexican pesos (average of USD$ 350/MT) on hand at December 31, 2020 that is classified as long-term in the accompanying Consolidated Statements of Financial Position. The Company follows the practice of providing a reserve for slow-moving inventory, considering the total of products and raw materials (including coke) with a turnover above one year, which is recorded in the statement of financial position and against account is the cost of sales. The cost of sales of the Company includes inventory costs, outbound freight charges, purchasing and receiving costs, inspection costs, and warehousing costs in cost of goods sold. Vendor payment incentives are recorded as a reduction to cost of goods sold.
Property, plant and equipment	f. Property plant and equipment – r An item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on the disposal or retirement of an item of property, plant and equipment is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in profit or loss. The initial estimated useful lives of the Company’s main assets are as follows: Years Buildings 10 to 65 Machinery and equipment 5 to 40 Transportation equipment 4 Furniture, chattels and computer equipment 3 to 10 Repair and maintenance costs that significantly increase productive capacity or extend the useful lives of existing plant and equipment are capitalized. Supplies, comprising of spare parts and consumables for internal use are classified under property, plant and equipment and expensed as incurred in the manufacturing process. All other repair and maintenance costs are expensed as incurred. Capital expenditures for projects that cannot be put into use immediately are included in constructions and machinery in-progress. When constructions and machinery in-progress are completed, they are transferred to depreciable assets.
Leases	g. Leases –
Costs for loans	h. Costs for loans – Investment income earned on the temporary investment of specific loans pending their expenditure on qualifying assets is deducted from the costs for loans eligible for capitalization. All other costs for loans are recognized in profit or loss in the period in which they are incurred.
Intangible assets	i. Intangible assets – Expenditure on research activities is recognized as an expense in the period in which it is incurred. An internally-generated intangible asset arising from development (or from the development phase of an internal project) is recognized if, and only if, all of the following have been demonstrated: - The technical feasibility of completing the intangible asset so that it will be available for use or sale; - The intention to complete the intangible asset and use or sell it; - The ability to use or sell the intangible asset; - How the intangible asset will generate probable future economic benefits; - The availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and - The ability to measure reliably the expenditure attributable to the intangible asset during its development. The amount initially recognized for internally-generated intangible assets is the sum of the expenditure incurred from the date when the intangible asset first meets the recognition criteria listed above. Where no internally-generated intangible asset can be recognized, development expenditure is recognized in profit or loss in the period in which it is incurred. Subsequent to initial recognition, internally-generated intangible assets are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately. Intangible assets acquired in a business combination and recognized separately from goodwill are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Subsequent to initial recognition, intangible assets acquired in a business combination are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately. An intangible asset is derecognized on disposal, or when no future economic benefits are expected from use or disposal. Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in profit or loss.
Goodwill	j. Goodwill –
Impairment of tangible and intangible assets other than goodwill	k. Impairment of tangible and intangible assets other than goodwill – An impairment loss is recognized immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease. Where an impairment loss subsequently reverses, the carrying amount of the asset (or a cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. For purposes of allocation of goodwill when there is business combination will be distributed among each of the cash generating units of the acquiring entity, expected synergy benefits. A reversal of an impairment loss is recognized immediately in profit or loss and allocated to the assets of that unit, the carrying amount of an asset other than goodwill attributable to a reversal of an impairment loss of value shall not exceed the carrying amount that would have been obtained if had not recognized an impairment loss in value for the asset in prior periods. Unless the related asset is recognized at a revalued amount, in which case the reversal of the impairment loss is treated as a revaluation increase. The reversal of the impairment loss is recorded on profit and loss, unless the corresponding asset recognizes a restated amount, in which case the reversal of the impairment loss is treated as a restatement increase.
Provisions	l. Provisions The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the balance sheet date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, it´s carrying amount is the present value of those cash flows.
Employee benefits	m. Employee benefits – The retirement benefit liability is determined based on the present value of the defined benefit obligation at the date of the statement of financial position. Any compensation included in the determination of the liability premiums corresponds to seniority premiums for retirement. Actuarial gains and losses are recognized on profit or loss for the year. The retirement benefit liability and the related net cost of the period are determined under the projected unit credit method based on projected salaries and certain assumptions determined by independent actuaries. Liabilities for employee benefits recognized in the consolidated statement of financial position represent the present value of the defined benefit obligation. Republic operates various employee benefit plans. The contributions to these benefit plans are either contractually determined by the terms of a collective bargaining agreement with the United Steelworkers or they are under the terms of a defined contribution plan. Accordingly, the company pays fixed contributions to separate entities and they are expensed in the period in which the employees rendered the services entitling them to the benefits.
Earnings per share	n. Earnings per share –
Income taxes	o. Income taxes – - Current tax - Deferred tax The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced by a valuation allowance to the extent that it is no longer probable that sufficient taxable earnings will be available to allow all or part of the asset to be recovered. Deferred tax assets and liabilities are computed using the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the balance sheet date. The effects of changes in the statutory rates are accounted for in the period that includes the enactment date. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Company expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends to settle its current tax assets and liabilities on a net basis. The Company follows the practice of recognizing the benefit from the amortization of acquired or generated tax losses in current earnings that are amortized. - Current and deferred tax for the period - Interests on recoverable tax balances
Foreign currencies	p. Foreign currencies – Exchange differences are recognized in profit or loss in the period in which they arise except for: - Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the cost of those assets and are recorded as an adjustment to interest costs on those foreign currency borrowings; - Exchange differences on transactions entered into in order to hedge certain foreign currency risks; and - Exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither planned nor likely to occur (therefore forming part of the net investment in the foreign operation), which are recognized initially in other comprehensive income and reclassified from equity to profit or loss on sale of all or part of the net investment.
Financial instruments	q. Financial instruments – Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at fair value through profit or loss are recognized immediately in profit or loss.
Financial assets	r. Financial assets – The effective interest method is a method of calculating the amortized cost of a debt instrument and of allocating interest income over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash receipts (including all fees and points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the debt instrument, or, (where appropriate), a shorter period, to the net carrying amount on initial recognition. The Company does not have financial assets classified as “available-for-sale financial assets”. Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and accounts receivable are measured at amortized cost using the effective interest method, less any impairment. Financial assets are assessed for indicators of impairment at the end of each reporting period. Financial assets are considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of the investment have been affected. Objective evidence of impairment could include: - Significant financial difficulty of the issuer or counterparty; - Breach of contract, such as a default or delinquency in interest or principal payments; - It becoming probable that the borrower will enter bankruptcy or financial re-organization; or - The disappearance of an active market for that financial asset because of financial difficulties. For certain categories of financial assets, such as trade receivables, assets that are assessed not to be impaired individually are, in addition, assessed for impairment on a collective basis. Objective evidence of impairment for a portfolio of receivables could include the Company’s past experience of collecting payments, as well as observable changes in national or local economic conditions that correlate with default on receivables. For financial assets carried at amortized cost, the amount of the impairment loss recognized is the difference between the asset’s carrying amount and the present value of estimated future cash flows, discounted at the financial asset’s original effective interest rate. The carrying amount of the financial asset is reduced by the impairment loss directly for all financial assets with the exception of trade receivables, where the carrying amount is reduced through the use of an allowance account. When a trade receivable is considered uncollectible, it is written off against the allowance account. Subsequent recoveries of amounts previously written off are credited against the allowance account. Changes in the carrying amount of the allowance account are recognized in profit or loss. Except for equity instruments available for sale, if, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss is reversed through profit or loss to the extent that the carrying amount of the investment at the date the impairment is reversed does not exceed what the amortized cost would have been had the impairment not been recognized. The Company recognizes a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another entity. If the Company neither transfers nor retains substantially all the risks and rewards of ownership and continues to control the transferred asset, the Company recognizes its retained interest in the asset and an associated liability for amounts it may have to pay. If the Company retains substantially all the risks and rewards of ownership of a transferred financial asset, the Company continues to recognize the financial asset and also recognizes a collateralized borrowing for the proceeds received. On recognition totally a financial asset, the difference between the carrying amount of an asset and the sum of the consideration received and receivable and the cumulative gain or loss that had been recognized in other comprehensive income and accumulated in equity is recognized in profit or loss. When the financial asset is partially derecognized (when the Company retains the option to repurchase part of a transferred asset, or retains residual interest that does not result in the retention of substantial risks and rewards of ownership and the Company retains control), the Company will distribute the initial value of the financial asset between the part that continues to be recognized and the part that is no longer recognized based on the fair values ​​of various parts as of the transfer date. The difference between the book value assigned to the part that is no longer recognized and the sum of the consideration received by such part; and any accumulated profit or loss assigned to it that has been recognized in other comprehensive income will be recognized in the consolidated income statement.
Financial liabilities	s. Financial liabilities – Financial liability at fair value with changes through profit or loss is a financial liability classified as held for trading or it is designated as at fair value with changes through profit or loss. A financial liability is classified as held for trading if: - It has been acquired principally for the purpose of repurchasing it in the near term; - On initial recognition, it is part of a portfolio of identified financial instruments that the Company manages together and has a recent actual pattern of short-term profit-taking; or - It is a derivative that has not been designated as a hedging instrument and fulfils the condition to be effective. A financial liability other than a financial liability held for trading may be designated as at fair value through profit or loss upon initial recognition if: - Such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise; or - The yield of a group of financial assets, financial liabilities or both, is administered and assessed based on its fair value, according to an investment strategy or risk management that the Company has documented and provided internal information over that group, based on its fair value; or - The financial liability forms part of a group of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair value basis, in accordance with the Company’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or - It forms part of a contract containing one or more embedded derivatives, and IAS 39, Financial Instruments: Recognition and Measurement, - Financial liabilities at fair value through profit or loss are recorded at fair value, with any gains or losses arising on remeasurement recognized in profit or loss. The net gain or loss recognized in profit or loss incorporates any interest paid on the financial liability and is included in the ‘other gains and losses’ line item in the consolidated statement of comprehensive income. - Other financial liabilities including borrowings are subsequently measured at amortized cost using the effective interest method. The effective interest method is a method of calculating the amortized cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the expected life of the financial liability, or (where appropriate a shorter period), to the net carrying amount on initial recognition. - The Company derecognizes financial liabilities when, and only when, the Company’s obligations are discharged, cancelled or expire. The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable is recognized in profit or loss at that time.
Derivative financial instruments	t. Derivative financial instruments – These derivatives are initially recognized at fair value at the date the derivative contracts are entered into and subsequently are remeasured to the fair value at the end of reporting period. The resulting gain or loss is recognized in profit or loss immediately unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship. To mitigate the risks associated with changes in natural gas prices occurring naturally as a result of the supply and demand on international markets, the Company uses natural gas cash-flow exchange contracts or natural gas swaps to offset fluctuations in the price of natural gas, whereby the Company receives a floating price and pays a fixed price. Fluctuations in natural gas prices from volumes consumed are recognized as part of the Company’s operating cost. At the inception of the hedge relationship, the Company documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Company documents whether the hedging instrument is highly effective in offsetting exposure to changes in fair values or cash flows of the hedged item attributable to the hedged risk. The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income and accumulated under the heading of fair value of derivative financial instruments, The Company periodically evaluates the changes in cash flows of the derivative instrument to analyze if the swaps are highly effective for mitigating the exposure to natural gas price fluctuations. A hedge instrument is considered to be highly effective when changes in its fair value or cash flows of the primary position are compensated on a regular or cumulatively basis, by changes in fair value or cash flows of the hedging instrument in a range between 80% and 125%. Amounts previously recognized in other comprehensive income are reclassified to profit or loss in the periods when the hedged item is recognized in profit or loss, in the same line of the consolidated statement of comprehensive income as the recognized hedged item. However, when the hedged forecasted transaction results in the recognition of a non-financial asset or a non-financial liability, the gains and losses previously accumulated in equity are transferred from equity and included in the initial measurement of the cost of the non-financial asset or non-financial liability. Hedge accounting is discontinued when the Company revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exerted, or when it no longer qualifies for hedge accounting. Any gain or loss accumulated from the hedge instrument that had been recognized in other comprehensive income and accumulated in equity at that time remains in equity until the forecast transaction is ultimately recognized in profit or loss. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in equity is recognized immediately in profit or loss.
Revenue from contracts with customers	u. Revenue from contracts with customers – The Company’s revenues are mainly recognized at a point of time from sales to direct customers.The Company does not have any obligations to be fulfilled in the contracts, which are obligations to be fulfilled separately and in which a portion of the transaction price should be allocated, other than the delivery of products confirming to the specifications of a customer purchase order. When determining the transaction price for the sale of products, the Company would consider the possible effects of the variable consideration, the existence of important financing components, the consideration other than cash and the consideration payable to the client. Contract assets An asset of the contract is the right to obtain a consideration in exchange for the goods or services transferred to the client when that right is conditioned by something other than the passage of time. If the Company fulfills an obligation by transferring goods or services to a customer before the customer pays the consideration or before collection is due, an asset derived from the contract is recognized for the conditional consideration that the Company is entitled to collect. Accounts receivable An account receivable represents the company’s right to collect a consideration that is unconditional, that is, only the passage of time is required so that the payment of the consideration is payable. Contract liabilities A contract liability is the obligation of an entity to transfer goods or services to a customer from whom the entity has already received a consideration (advance from customers) or that consideration is already payable. If a customer pays a consideration, or the Company has an unconditional right to receive an amount as consideration before the Company transfers a good or service to the customer, the Company recognizes a contract liability when the payment is made or is due.
