Summary of Significant Accounting Policies (Policies)	12 Months Ended
Sep. 30, 2021
Accounting Policies [Abstract]
Description of Business	DESCRIPTION OF BUSINESSSIFCO Industries, Inc. and its subsidiaries are engaged in the production of forgings and machined components primarily in the Aerospace and Energy ("A&E") market. The Company’s operations are conducted in a single business segment, "SIFCO" or the "Company."
Principles of Consolidation	PRINCIPLES OF CONSOLIDATIONThe accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The U.S. dollar is the functional currency for all the Company’s U.S. operations and its non-operating subsidiaries. For these operations, all gains and losses from completed currency transactions are included in income. The functional currency for the Company's other non-U.S. subsidiaries is the Euro. Assets and liabilities are translated into U.S. dollars at the rates of exchange at the end of the period, and revenues and expenses are translated using average rates of exchange. Foreign currency translation adjustments are reported as a component of accumulated other comprehensive loss in the consolidated statements of shareholders’ equity.
Cash Equivalents	CASH EQUIVALENTSThe Company considers all highly liquid short-term investments with original maturities of three months or less to be cash equivalents.
Concentrations of Credit Risk	CONCENTRATIONS OF CREDIT RISK Receivables are presented net of allowance for doubtful accounts of $167 and $249 at September 30, 2021 and 2020, respectively. Accounts receivable outstanding longer than the contractual payment terms are considered past due. The Company writes off accounts receivable when they become uncollectible. During fiscal 2021 $9 of accounts receivable were recovered against the allowance for doubtful accounts while in fiscal 2020 $263 of accounts receivable were written off against the allowance for doubtful accounts. Bad debt benefit totaled $91 and $80 in fiscal 2021 and fiscal 2020, respectively. Most of the Company’s receivables represent trade receivables due from manufacturers of turbine engines and aircraft components as well as turbine engine overhaul companies located throughout the world, including a significant concentration of U.S. based companies. In fiscal 2021, 20% of the Company’s consolidated net sales were from two of its largest customers; and 38% of the Company's consolidated net sales were from the three largest customers and their direct subcontractors, which individually accounted for 17%, 11%, and 10%, of consolidated net sales, respectively. In fiscal 2020, 10% of the Company’s consolidated net sales were from one of its largest customers; and 49% of the Company's consolidated net sales were from four of the largest customers and their direct subcontractors which individually accounted for 16%, 13%, 10% and 10%, of consolidated net sales, respectively. Other than what has been disclosed, no other single customer or group represented greater than 10% of total net sales in fiscal 2021 and 2020. At September 30, 2021, none of the Company’s largest customers had outstanding net accounts receivable balances that were individually greater than 10% of the total net accounts receivable; and one of the largest customers and their direct subcontractors collectively had outstanding net accounts receivable which accounted for 17% of total net accounts receivable. At September 30, 2020, one of the Company’s largest customers had outstanding net accounts receivable which individually accounted for 11% of total net accounts receivable; and three of the largest customers and their direct subcontractors had outstanding net accounts receivable which accounted for 13%, 13%, and 12% of total net accounts receivable, respectively. The Company performs ongoing credit evaluations of its customers’ financial conditions. The Company believes its allowance for doubtful accounts is sufficient based on the credit exposures outstanding at September 30, 2021.
Inventory Valuation	INVENTORY VALUATIONFor a portion of the Company's inventory, cost is determined using the last-in, first-out (“LIFO”) method. For approximately 39% and 47% of the Company’s inventories at September 30, 2021 and 2020, respectively, the LIFO method is used to value the Company’s inventories. The first-in, first-out (“FIFO”) method is used to value the remainder of the Company’s inventories, which are stated at the lower cost or net realizable value.The Company maintains allowances for obsolete and excess inventory. The Company evaluates its allowances for obsolete and excess inventory each quarter and requires at a minimum that reserves be established based on an analysis of the age of the inventory. In addition, if the Company identifies specific obsolescence, other than that identified by the aging criteria, an additional reserve will be recognized. Specific obsolescence and excess reserve requirements may arise due to technological or market changes or based on cancellation of an order.
Property, Plant and Equipment	PROPERTY, PLANT AND EQUIPMENTProperty, plant and equipment are stated at cost. Depreciation is generally computed using the straight-line method. Depreciation is provided in amounts sufficient to amortize the cost of the assets over their estimated useful lives. Depreciation provisions are based on estimated useful lives: (i) buildings, including building improvements - 5 to 40 years; (ii) machinery and equipment, including office and computer equipment - 3 to 20 years; (iii) software - 3 to 7 years (included in machinery and equipment); and (iv) leasehold improvements - 6 to 15 years range represent the remaining life or length of the lease, whichever is less (included in buildings).The (gain) loss on disposal of operating assets is included as a separate line item in the accompanying consolidated statements of operations.
Asset Impairment	ASSET IMPAIRMENTThe Company reviews the carrying value of its long-lived assets ("asset groups"), including property, plant and equipment, when events and circumstances indicate a triggering event has occurred. This review is performed using estimates of future undiscounted cash flows, which include proceeds from disposal of assets. Under the Accounting Standard Codification ("ASC") 360 ("Topic 360"), if the carrying value of a long-lived asset is greater than the estimated undiscounted future cash flows, then the long-lived asset is considered impaired and an impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value.
Goodwill and Intangible Assets	GOODWILL AND INTANGIBLE ASSETS Goodwill represents the excess of the purchase price paid over the fair value of the net assets of an acquired business. Goodwill is subject to impairment testing if triggered in the interim, and if not, on an annual basis. The Company has selected July 31 as the annual impairment testing date. With the adoption of Accounting Standard Update ("ASU") 2017-04, Step 2 has been eliminated from the goodwill impairment test. The first step of the goodwill impairment test compares the fair value of a reporting unit (as defined) with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired. However, if the carrying amount exceeds the fair value, the Company should recognize an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to that reporting unit. See Note 3, Goodwill and Intangibles Assets, of the consolidated financial statements for further discussion of the July 31, 2021 and 2020 annual impairment test results. Intangible assets consist of identifiable intangibles acquired or recognized in the accounting for the acquisition of a business and include such items as a trade name, a non-compete agreement, below market lease, customer relationships and order backlog. Intangible assets are amortized over their useful lives ranging from one year to ten years. Identifiable intangible assets assessment for impairment is evaluated when events and circumstances warrant such a review, as noted within Note 1, Summary of Significant Accounting Policies - Asset Impairment, of the consolidated financial statements.
Net Income (Loss) Per Share	NET INCOME (LOSS) PER SHAREThe Company’s net loss and income per basic share has been computed based on the weighted-average number of common shares outstanding.
Revenue Recognition	REVENUE RECOGNITION The Company recognizes revenue using the five-step revenue recognition model in which it depicts the transfer of goods to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. The revenue standard also requires disclosure sufficient to enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments and assets recognized from the cost to obtain or fulfill a contract. Contract Balances Contract assets on the consolidated balance sheets are recognized when a good is transferred to the customer and the Company does not have the contractual right to bill for the related performance obligations. In these instances, revenue recognized exceeds the amount billed to the customer and the right to payment is not solely subject to the passage of time. Amounts do not exceed their net realizable value. Contract liabilities relate to payments received in advance of the satisfaction of performance under the contract. Payment from customers are received based on the terms established in the contract with the customer.
Leases	LEASES The leasing standard requires lessees to recognize a Right-of-Use ("ROU") asset and a lease liability on the consolidated balance sheet, with the exception of short-term leases. The Company primarily leases its manufacturing buildings, specifically at its Orange location, as well as certain machinery and office equipment. The Company determines if a contract contains a lease based on whether the contract conveys the right to control the use of identified assets for a period in exchange for consideration. Upon identification and commencement of a lease, the Company establishes a ROU asset and a lease liability. Operating leases are included in ROU assets, short-term operating lease liabilities, and long-term operating lease liabilities on the consolidated balance sheets. Finance leases are included in property, plant, and equipment, current maturities of long-term debt and long-term debt on the consolidated balance sheets. ROU assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the leases do not provide an implicit rate, the Company uses the incremental borrowing rate based on the information available at commencement date and duration of the lease term in determining the present value of the future payments. Lease expense for operating leases is recognized on a straight-line basis over the lease term, while the expense for finance leases is recognized as depreciation expense and interest expense using the accelerated interest method of recognition.
Impact of Recently Adopted and Newly Issued Accounting Standards	IMPACT OF RECENTLY ADOPTED ACCOUNTING STANDARDS In August 2018, the FASB issued ASU 2018-14, "Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20)," which adds the following disclosure requirements: (1) the weighted-average interest crediting rates used in the Company's cash balance pension plans and other similar plans; (2) a narrative description of the reasons for significant gains and losses affecting the benefit obligation for the period; and (3) an explanation of any other significant changes in the benefit obligation or plan assets that are not otherwise apparent in the other disclosures required by Accounting Standards Codification ("ASC") Topic 715, "Compensation - Retirement Benefits." The ASU also clarifies the guidance included in ASC 715-20-50-3 on defined benefit plans disclosure requirements. This ASU is effective for the Company and did not have a material impact to the pension disclosures. See Note 8, Retirement Benefit Plans, of the consolidated financial statements for further information. M. IMPACT OF NEWLY ISSUED ACCOUNTING STANDARDS In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" and subsequent updates. ASU 2016-13 changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The new guidance will replace the current incurred loss approach with an expected loss model. The new expected credit loss impairment model will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt instruments, net investments in leases, loan commitments and standby letters of credit. Upon initial recognition of the exposure, the expected credit loss model requires entities to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses should consider historical information, current information and reasonable and supportable forecasts, including estimates of prepayments. Financial instruments with similar risk characteristics should be grouped together when estimating expected credit losses. ASU 2016-13 does not prescribe a specific method to make the estimate, so its application will require significant judgment. ASU 2016-13 is effective for public companies in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. However, in November 2019, the FASB issued ASU 2019-10, "Financial Instruments - Credit Loss (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842)," which defers the effective date for public filers that qualify as a smaller reporting company ("SRC"), as defined by the Securities and Exchange Commission, to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Because SIFCO is considered a SRC, the Company does not need to implement this standard until October 1, 2023. The Company will continue to evaluate the effect of adopting ASU 2016-13 will have on the Company's results within the consolidated statements of operations and financial condition. In December 2019, ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes" was issued to (i) reduce the complexity of the standard by removing certain exceptions to the general principles in Topic 740 and (ii) improve consistency and simplify other areas of Topic 740 by clarifying and amending existing guidance. This ASU is effective beginning October 1, 2021. The adoption of this ASU is not expected to have a material impact to the Company's results within the consolidated statements of operations and financial condition. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which is intended to provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates. This ASU, along with recently issued ASU 2021-01, which further clarifies the scope of Topic 848, is available immediately and may be implemented in any period prior to the guidance expiration on December 31, 2022. ASU 2020-04 was effective beginning on March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company has not applied any optional expedients and exceptions to date, and will continue to evaluate the impact of the guidance and whether it will apply the optional expedients and exceptions.
Use of Estimates	USE OF ESTIMATESAccounting principles generally accepted in the U.S. require management to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent liabilities, at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the period in preparing these financial statements. Actual results could differ from those estimates.
Research and Development	RESEARCH AND DEVELOPMENTResearch and development costs are expensed as they are incurred. Research and development expenses were nominal in fiscal 2021 and 2020.
Debt Issuance Costs	DEBT ISSUANCE COSTSDebt issuance costs are capitalized and amortized over the life of the related debt. Amortization of debt issuance costs is included in interest expense in the consolidated statements of operations.
Income Taxes	INCOME TAXES The Company files a consolidated U.S. federal income tax return and tax returns in various state and local jurisdictions. The Company’s Irish and Italian subsidiaries also file tax returns in their respective jurisdictions. The Company provides deferred income taxes for the temporary difference between the financial reporting basis and tax basis of the Company’s assets and liabilities. Such taxes are measured using the enacted tax rates that are assumed to be in effect when the differences reverse. Deductible temporary differences result principally from recording certain expenses in the financial statements in excess of amounts currently deductible for tax purposes. Taxable temporary differences result principally from tax depreciation in excess of book depreciation. The Company evaluates for uncertain tax positions taken at each balance sheet date. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest cumulative benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company's policy for interest and/or penalties related to underpayments of income taxes is to include interest and penalties in tax expenses. The Company maintains a valuation allowance against its deferred tax assets when management believes it is more likely than not that all or a portion of a deferred tax asset may not be realized. Changes in valuation allowances are recorded in the period of change. In determining whether a valuation allowance is warranted, the Company evaluates factors such as prior earnings history, expected future earnings, carry-back and carry-forward periods and tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. The Tax Cut and Jobs Act (the "Act") includes provisions for Global Intangible Low-Taxed Income (“GILTI”) wherein minimum taxes are imposed on foreign income in excess of a deemed return on the tangible assets of foreign corporations. This income will effectively be taxed at a 10.5% tax rate. GILTI was effective for the Company starting in fiscal 2019. The Company has elected to account for GILTI as a component of tax expense in the period in which the Company is subject to the rules.
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. In determining fair value, the Company utilizes certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. Based on the examination of the inputs used in the valuation techniques, the Company is required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories: Level 1 - Quoted market prices in active markets for identical assets or liabilities Level 2 - Observable market based inputs or unobservable inputs that are corroborated by market data Level 3 - Unobservable inputs that are not corroborated by market data A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The book value of cash equivalents, accounts receivable, and accounts payable are considered to be representative of their fair values because of their short maturities. The carrying value of debt is considered to approximate the fair value based on the borrowing rates currently available to us for loans with similar terms and maturities. Fair value measurements of non-financial assets and non-financial liabilities are primarily used in goodwill, other intangible assets and long-lived assets impairment analysis, the valuation of acquired intangibles and in the valuation of assets held for sale. Goodwill and intangible assets are valued using Level 3 inputs.
Share-based Compensation	SHARE-BASED COMPENSATIONShare-based compensation is measured at the grant date, based on the calculated fair value of the award and the probability of meeting its performance condition, and is recognized as expense when it is probable that the performance conditions will be met over the requisite service period (generally the vesting period). Share-based expense includes expense related to restricted shares and performance shares issued under the Company's 2007 Plan Long-Term Incentive Plan (Amended and Restated as of November 16, 2016) (as further amended, the "2016 Plan"). The Company recognizes share-based expense within selling, general, and administrative expense and adjusts for any forfeitures as they occur.

DESCRIPTION OF BUSINESSSIFCO Industries, Inc. and its subsidiaries are engaged in the production of forgings and machined components primarily in the Aerospace and Energy ("A&E") market. The Company’s operations are conducted in a single business segment, "SIFCO" or the "Company."

Principles of Consolidation

PRINCIPLES OF CONSOLIDATIONThe accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The U.S. dollar is the functional currency for all the Company’s U.S. operations and its non-operating subsidiaries. For these operations, all gains and losses from completed currency transactions are included in income. The functional currency for the Company's other non-U.S. subsidiaries is the Euro. Assets and liabilities are translated into U.S. dollars at the rates of exchange at the end of the period, and revenues and expenses are translated using average rates of exchange. Foreign currency translation adjustments are reported as a component of accumulated other comprehensive loss in the consolidated statements of shareholders’ equity.

Cash Equivalents

CASH EQUIVALENTSThe Company considers all highly liquid short-term investments with original maturities of three months or less to be cash equivalents.

Concentrations of Credit Risk

CONCENTRATIONS OF CREDIT RISK

Receivables are presented net of allowance for doubtful accounts of $167 and $249 at September 30, 2021 and 2020, respectively. Accounts receivable outstanding longer than the contractual payment terms are considered past due. The Company writes off accounts receivable when they become uncollectible. During fiscal 2021 $9 of accounts receivable were recovered against the allowance for doubtful accounts while in fiscal 2020 $263 of accounts receivable were written off against the allowance for doubtful accounts. Bad debt benefit totaled $91 and $80 in fiscal 2021 and fiscal 2020, respectively.

Most of the Company’s receivables represent trade receivables due from manufacturers of turbine engines and aircraft components as well as turbine engine overhaul companies located throughout the world, including a significant concentration of U.S. based companies. In fiscal 2021, 20% of the Company’s consolidated net sales were from two of its largest customers; and 38% of the Company's consolidated net sales were from the three largest customers and their direct subcontractors, which individually accounted for 17%, 11%, and 10%, of consolidated net sales, respectively. In fiscal 2020, 10% of the Company’s consolidated net sales were from one of its largest customers; and 49% of the Company's consolidated net sales were from four of the largest customers and their direct subcontractors which individually accounted for 16%, 13%, 10% and 10%, of consolidated net sales, respectively. Other than what has been disclosed, no other single customer or group represented greater than 10% of total net sales in fiscal 2021 and 2020.

At September 30, 2021, none of the Company’s largest customers had outstanding net accounts receivable balances that were individually greater than 10% of the total net accounts receivable; and one of the largest customers and their direct subcontractors collectively had outstanding net accounts receivable which accounted for 17% of total net accounts receivable. At September 30, 2020, one of the Company’s largest customers had outstanding net accounts receivable which individually accounted for 11% of total net accounts receivable; and three of the largest customers and their direct subcontractors had outstanding net accounts receivable which accounted for 13%, 13%, and 12% of total net accounts receivable, respectively. The Company performs ongoing credit evaluations of its customers’ financial conditions. The Company believes its allowance for doubtful accounts is sufficient based on the credit exposures outstanding at September 30, 2021.

Inventory Valuation

INVENTORY VALUATIONFor a portion of the Company's inventory, cost is determined using the last-in, first-out (“LIFO”) method. For approximately 39% and 47% of the Company’s inventories at September 30, 2021 and 2020, respectively, the LIFO method is used to value the Company’s inventories. The first-in, first-out (“FIFO”) method is used to value the remainder of the Company’s inventories, which are stated at the lower cost or net realizable value.The Company maintains allowances for obsolete and excess inventory. The Company evaluates its allowances for obsolete and excess inventory each quarter and requires at a minimum that reserves be established based on an analysis of the age of the inventory. In addition, if the Company identifies specific obsolescence, other than that identified by the aging criteria, an additional reserve will be recognized. Specific obsolescence and excess reserve requirements may arise due to technological or market changes or based on cancellation of an order.

Property, Plant and Equipment

PROPERTY, PLANT AND EQUIPMENTProperty, plant and equipment are stated at cost. Depreciation is generally computed using the straight-line method. Depreciation is provided in amounts sufficient to amortize the cost of the assets over their estimated useful lives. Depreciation provisions are based on estimated useful lives: (i) buildings, including building improvements - 5 to 40 years; (ii) machinery and equipment, including office and computer equipment - 3 to 20 years; (iii) software - 3 to 7 years (included in machinery and equipment); and (iv) leasehold improvements - 6 to 15 years range represent the remaining life or length of the lease, whichever is less (included in buildings).The (gain) loss on disposal of operating assets is included as a separate line item in the accompanying consolidated statements of operations.

Asset Impairment

ASSET IMPAIRMENTThe Company reviews the carrying value of its long-lived assets ("asset groups"), including property, plant and equipment, when events and circumstances indicate a triggering event has occurred. This review is performed using estimates of future undiscounted cash flows, which include proceeds from disposal of assets. Under the Accounting Standard Codification ("ASC") 360 ("Topic 360"), if the carrying value of a long-lived asset is greater than the estimated undiscounted future cash flows, then the long-lived asset is considered impaired and an impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its fair value.

Goodwill and Intangible Assets

GOODWILL AND INTANGIBLE ASSETS

Goodwill represents the excess of the purchase price paid over the fair value of the net assets of an acquired business. Goodwill is subject to impairment testing if triggered in the interim, and if not, on an annual basis. The Company has selected July 31 as the annual impairment testing date. With the adoption of Accounting Standard Update ("ASU") 2017-04, Step 2 has been eliminated from the goodwill impairment test. The first step of the goodwill impairment test compares the fair value of a reporting unit (as defined) with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not considered impaired. However, if the carrying amount exceeds the fair value, the Company should recognize an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to that reporting unit. See Note 3, Goodwill and Intangibles Assets, of the consolidated financial statements for further discussion of the July 31, 2021 and 2020 annual impairment test results.

Intangible assets consist of identifiable intangibles acquired or recognized in the accounting for the acquisition of a business and include such items as a trade name, a non-compete agreement, below market lease, customer relationships and order backlog. Intangible assets are amortized over their useful lives ranging from one year to ten years. Identifiable intangible assets assessment for impairment is evaluated when events and circumstances warrant such a review, as noted within Note 1, Summary of Significant Accounting Policies - Asset Impairment, of the consolidated financial statements.

Net Income (Loss) Per Share

NET INCOME (LOSS) PER SHAREThe Company’s net loss and income per basic share has been computed based on the weighted-average number of common shares outstanding.

Revenue Recognition

REVENUE RECOGNITION

The Company recognizes revenue using the five-step revenue recognition model in which it depicts the transfer of goods to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. The revenue standard also requires disclosure sufficient to enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments and assets recognized from the cost to obtain or fulfill a contract.

Contract Balances

Contract assets on the consolidated balance sheets are recognized when a good is transferred to the customer and the Company does not have the contractual right to bill for the related performance obligations. In these instances, revenue recognized exceeds the amount billed to the customer and the right to payment is not solely subject to the passage of time. Amounts do not exceed their net realizable value. Contract liabilities relate to payments received in advance of the satisfaction of performance under the contract. Payment from customers are received based on the terms established in the contract with the customer.

Leases

LEASES

The leasing standard requires lessees to recognize a Right-of-Use ("ROU") asset and a lease liability on the consolidated balance sheet, with the exception of short-term leases. The Company primarily leases its manufacturing buildings, specifically at its Orange location, as well as certain machinery and office equipment. The Company determines if a contract contains a lease based on whether the contract conveys the right to control the use of identified assets for a period in exchange for consideration. Upon identification and commencement of a lease, the Company establishes a ROU asset and a lease liability. Operating leases are included in ROU assets, short-term operating lease liabilities, and long-term operating lease liabilities on the consolidated balance sheets. Finance leases are included in property, plant, and equipment, current maturities of long-term debt and long-term debt on the consolidated balance sheets.

ROU assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the leases do not provide an implicit rate, the Company uses the incremental borrowing rate based on the information available at commencement date and duration of the lease term in determining the present value of the future payments. Lease expense for operating leases is recognized on a straight-line basis over the lease term, while the expense for finance leases is recognized as depreciation expense and interest expense using the accelerated interest method of recognition.

Impact of Recently Adopted and Newly Issued Accounting Standards

IMPACT OF RECENTLY ADOPTED ACCOUNTING STANDARDS

In August 2018, the FASB issued ASU 2018-14, "Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20)," which adds the following disclosure requirements: (1) the weighted-average interest crediting rates used in the Company's cash balance pension plans and other similar plans; (2) a narrative description of the reasons for significant gains and losses affecting the benefit obligation for the period; and (3) an explanation of any other significant changes in the benefit obligation or plan assets that are not otherwise apparent in the other disclosures required by Accounting Standards Codification ("ASC") Topic 715, "Compensation - Retirement Benefits." The ASU also clarifies the guidance included in ASC 715-20-50-3 on defined benefit plans disclosure requirements. This ASU is effective for the Company and did not have a material impact to the pension disclosures. See Note 8, Retirement Benefit Plans, of the consolidated financial statements for further information.

M. IMPACT OF NEWLY ISSUED ACCOUNTING STANDARDS

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" and subsequent updates. ASU 2016-13 changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The new guidance will replace the current incurred loss approach with an expected loss model. The new expected credit loss impairment model will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt instruments, net investments in leases, loan commitments and standby letters of credit. Upon initial recognition of the exposure, the expected credit loss model requires entities to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses should consider historical information, current information and reasonable and supportable forecasts, including estimates of prepayments. Financial instruments with similar risk characteristics should be grouped together when estimating expected credit losses. ASU 2016-13 does not prescribe a specific method to make the estimate, so its application will require significant judgment. ASU 2016-13 is effective for public companies in fiscal years beginning after December 15, 2019, including interim periods within those fiscal

years. However, in November 2019, the FASB issued ASU 2019-10, "Financial Instruments - Credit Loss (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842)," which defers the effective date for public filers that qualify as a smaller reporting company ("SRC"), as defined by the Securities and Exchange Commission, to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Because SIFCO is considered a SRC, the Company does not need to implement this standard until October 1, 2023. The Company will continue to evaluate the effect of adopting ASU 2016-13 will have on the Company's results within the consolidated statements of operations and financial condition.

In December 2019, ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes" was issued to (i) reduce the complexity of the standard by removing certain exceptions to the general principles in Topic 740 and (ii) improve consistency and simplify other areas of Topic 740 by clarifying and amending existing guidance. This ASU is effective beginning October 1, 2021. The adoption of this ASU is not expected to have a material impact to the Company's results within the consolidated statements of operations and financial condition.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which is intended to provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates. This ASU, along with recently issued ASU 2021-01, which further clarifies the scope of Topic 848, is available immediately and may be implemented in any period prior to the guidance expiration on December 31, 2022. ASU 2020-04 was effective beginning on March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company has not applied any optional expedients and exceptions to date, and will continue to evaluate the impact of the guidance and whether it will apply the optional expedients and exceptions.

Use of Estimates

USE OF ESTIMATESAccounting principles generally accepted in the U.S. require management to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent liabilities, at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the period in preparing these financial statements. Actual results could differ from those estimates.

Research and Development

RESEARCH AND DEVELOPMENTResearch and development costs are expensed as they are incurred. Research and development expenses were nominal in fiscal 2021 and 2020.

Debt Issuance Costs

DEBT ISSUANCE COSTSDebt issuance costs are capitalized and amortized over the life of the related debt. Amortization of debt issuance costs is included in interest expense in the consolidated statements of operations.

Income Taxes

INCOME TAXES

The Company files a consolidated U.S. federal income tax return and tax returns in various state and local jurisdictions. The Company’s Irish and Italian subsidiaries also file tax returns in their respective jurisdictions.

The Company provides deferred income taxes for the temporary difference between the financial reporting basis and tax basis of the Company’s assets and liabilities. Such taxes are measured using the enacted tax rates that are assumed to be in effect when the differences reverse. Deductible temporary differences result principally from recording certain expenses in the financial statements in excess of amounts currently deductible for tax purposes. Taxable temporary differences result principally from tax depreciation in excess of book depreciation.

The Company evaluates for uncertain tax positions taken at each balance sheet date. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest cumulative benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company's policy for interest and/or penalties related to underpayments of income taxes is to include interest and penalties in tax expenses.

The Company maintains a valuation allowance against its deferred tax assets when management believes it is more likely than not that all or a portion of a deferred tax asset may not be realized. Changes in valuation allowances are recorded in the period of change. In determining whether a valuation allowance is warranted, the Company evaluates factors such as prior earnings history, expected future earnings, carry-back and carry-forward periods and tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset.

The Tax Cut and Jobs Act (the "Act") includes provisions for Global Intangible Low-Taxed Income (“GILTI”) wherein minimum taxes are imposed on foreign income in excess of a deemed return on the tangible assets of foreign corporations. This income will effectively be taxed at a 10.5% tax rate. GILTI was effective for the Company starting in fiscal 2019. The Company has elected to account for GILTI as a component of tax expense in the period in which the Company is subject to the rules.

Fair Value Measurements

FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. In determining fair value, the Company utilizes certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. Based on the examination of the inputs used in the valuation techniques, the Company is required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values.

Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:

Level 1 - Quoted market prices in active markets for identical assets or liabilities

Level 2 - Observable market based inputs or unobservable inputs that are corroborated by market data

Level 3 - Unobservable inputs that are not corroborated by market data

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The book value of cash equivalents, accounts receivable, and accounts payable are considered to be representative of their fair values because of their short maturities. The carrying value of debt is considered to approximate the fair value based on the borrowing rates currently available to us for loans with similar terms and maturities. Fair value measurements of non-financial assets and non-financial liabilities are primarily used in goodwill, other intangible assets and long-lived assets impairment analysis, the valuation of acquired intangibles and in the valuation of assets held for sale. Goodwill and intangible assets are valued using Level 3 inputs.

Share-based Compensation

SHARE-BASED COMPENSATIONShare-based compensation is measured at the grant date, based on the calculated fair value of the award and the probability of meeting its performance condition, and is recognized as expense when it is probable that the performance conditions will be met over the requisite service period (generally the vesting period). Share-based expense includes expense related to restricted shares and performance shares issued under the Company's 2007 Plan Long-Term Incentive Plan (Amended and Restated as of November 16, 2016) (as further amended, the "2016 Plan"). The Company recognizes share-based expense within selling, general, and administrative expense and adjusts for any forfeitures as they occur.
