Notes to Financial Statements
Significant Accounting Policies [Text Block]	Note 1 Summary of Significant Accounting Policies General Information and Basis of Presentation The Gorman-Rupp Company is a leading designer, manufacturer and international marketer of pumps and pump systems for use in diverse water, wastewater, construction, dewatering, industrial, petroleum, original equipment, agriculture, fire suppression, heating, ventilating and air conditioning (HVAC), military and other liquid-handling applications. The Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles and include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated. Earnings per share are calculated based on the weighted-average number of common shares outstanding. Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates. Cash Equivalents and Short-Term Investments The Company considers highly liquid instruments with maturities of 90 days or less to be cash equivalents. The Company periodically makes short-term investments for which cost approximates fair value. Short-term investments at December 31, 2022 and 2021 consisted primarily of a certificate of deposit and is classified as Prepaid and other on the Consolidated Balance Sheets. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are stated at the historical carrying amount net of allowance for doubtful accounts. The Company maintains an allowance for doubtful accounts for expected losses from the failure of its customers to make required payments for products delivered. The Company estimates this allowance based on knowledge of the financial condition of customers, review of historical receivables and reserve trends, current economic conditions in the company’s major markets and geographies, and other relevant information. Inventories The majority of the Company’s inventories are valued on the last-in, first-out (LIFO) method and stated at the lower of cost or market. All other inventories are stated at the lower of cost or net realizable value with cost determined using the first-in, first-out (FIFO) method. Cost components include materials, inbound freight costs, labor and allocations of fixed and variable overheads on an absorption costing basis. The costs for approximately 68% and 72% of inventories at December 31, 2022 and 2021, respectively, were determined using the last-in, first-out (LIFO) method. Current cost approximates replacement cost, or market, and LIFO cost is determined at the end of each fiscal year based on inventory levels on-hand at current replacement cost and a LIFO reserve. The Company uses the simplified LIFO method, under which the LIFO reserve is determined utilizing the inflation factor specified in the Producer Price Index for Machinery and Equipment – Pumps, Compressors and Equipment, as published by the U.S. Bureau of Labor Statistics. Interim LIFO calculations are based on management’s estimate of the expected year-end inflation index and, as such, are subject to adjustment each quarter including the fourth quarter when the inflation index for the year is finalized. When inflation increases, the LIFO reserve and non-cash expense increase. Property, plant and equipment Property, plant and equipment are stated on the basis of cost. Repairs and maintenance costs are expensed as incurred. Depreciation for property, plant and equipment assets is computed using the straight-line method over the estimated useful lives of the assets and is included in Cost of products sold and Selling, general and administrative expenses based on the use of the assets. Depreciation expense was $13.3 million, $11.2 million, and $11.4 million for 2022, 2021, and 2020, respectively. Depreciation of property, plant and equipment is determined based on the following lives: Years Buildings 20 - 50 Machinery and equipment 5 - 15 Software 3 - 5 Property, plant and equipment consist of the following: 2022 2021 Land $ 6,215 $ 5,813 Buildings 119,197 112,760 Machinery and equipment 212,581 188,123 337,993 306,696 Less accumulated depreciation (209,353 ) (202,403 ) Property, plant and equipment, net $ 128,640 $ 104,293 Property, plant and equipment are evaluated for impairment whenever events or changes in circumstances indicate the carrying amount may not be recovered through future net cash flows generated by the assets. Impairment losses may be recorded when the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts based on the excess of the carrying amounts over the estimated fair value of the assets. The Company was not aware of any events or changes in circumstances that indicated the carrying value of its property, plant and equipment may not be recoverable. Goodwill and Identifiable Intangible Assets Goodwill Goodwill represents the excess of the cost of acquired businesses over the fair value of tangible assets and identifiable intangible assets purchased and liabilities assumed. Goodwill is reviewed annually for impairment as of October 1 or whenever events or changes in circumstances indicate there may be a possible permanent loss of value using either a quantitative or qualitative analysis. For certain reporting units, the Company performs a quantitative analysis using both a market-based approach and a discounted cash flow model to estimate the fair value of our reporting units. This process requires significant judgements, including estimation of future cash flows, which is dependent on internal forecasts. The Company may otherwise elect to perform a qualitative analysis when deemed appropriate. A qualitative analysis may be performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative assessment. No Identifiable intangible assets The Company’s primary identifiable intangible assets include customer relationships, technology and drawings, and trade names and trademarks. Identifiable intangible assets with finite lives are amortized and those identifiable intangible assets with indefinite lives are not amortized. Amortization for finite-lived intangible assets is computed using the straight-line method over the estimated useful lives of the assets and is included in Cost of products sold and Selling, general and administrative expenses based on the use of the assets. Amortization of finite-lived intangible assets is determined based on the following lives: Years Technology and drawings 13 - 20 Customer relationships 9 - 20 Other intangibles 2 - 18 Identifiable intangible assets that are subject to amortization are evaluated for impairment whenever events or changes in circumstances indicate the carrying amount may not be recovered through future net cash flows generated by the assets. Impairment losses may be recorded when the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts based on the excess of the carrying amounts over the estimated fair value of the assets. The Company was not aware of any events or changes in circumstances that indicated the carrying value of its finite-lived intangible assets may not be recoverable. Identifiable intangible assets not subject to amortization are tested for impairment annually or more frequently if events warrant. The fair value of these assets is determined using a royalty relief methodology similar to that employed when the associated assets were acquired, but using updated estimates of future sales, cash flows and profitability. For 2022, 2021 and 2020, the fair value of indefinite lived intangible assets exceeded their carrying values. For additional information about goodwill and other intangible assets, see Note 11 to the Consolidated Financial Statements, Goodwill and Other Intangible Assets. Acquisitions The Company allocates the purchase price of its acquisitions to the assets acquired, liabilities assumed, and noncontrolling interests based upon their respective fair values at the acquisition date. The Company utilizes management estimates and inputs from an independent third-party valuation firm to assist in determining these fair values. The Company uses the income, market or cost approach (or a combination thereof) for the valuation as appropriate. The valuation inputs in these models and analyses are based on market participant assumptions. Management values property, plant and equipment using the cost approach supported where available by observable market data, which includes consideration of obsolescence. Management values acquired intangible assets using the relief from royalty method or excess earnings method, which are forms of the income approach supported by observable market data for peer companies. The significant assumptions used to estimate the value of the acquired intangible assets include discount rates and certain assumptions that form the basis of future cash flows (such as revenue growth rates, EBITDA margins, customer attrition rates, and royalty rates), which are considered Level 3 assets as the assumptions are unobservable inputs developed by the Company. Acquired inventories are recorded at fair value. For certain items, the carrying value is determined to be a reasonable approximation of fair value based on information available to the Company. The excess of the acquisition price over estimated fair values is recorded as goodwill. Goodwill is adjusted for any changes to acquisition date fair value amounts made within the measurement period. Acquisition-related transaction costs are recognized separately from the business combination and expensed as incurred. See Note 2 to the Consolidated Financial Statements, “Acquisitions”. Revenue Recognition The Company recognizes revenue when it transfers control of promised goods or services to its customers in an amount that reflects the consideration to which it expects to be entitled to in exchange for those goods or services. Performance Obligations A performance obligation is a promise in a contract to transfer a distinct product or service to a customer, and is the unit of account in ASC 606. The transaction price for a customer contract is allocated to each distinct performance obligation and recognized as revenue when, or as, the Company’s performance obligation is satisfied. For product sales, other than long-term construction-type contracts, the Company recognizes revenue once control has passed at a point in time, which is generally when products are shipped. Payments received for product sales typically occur following delivery and the satisfaction of the performance obligation based upon the terms outlined in the contracts. Substantially all of our customer contracts are fixed-price contracts and the majority of our customer contracts have a single performance obligation, as the promise to transfer the individual products or services is not separately identifiable from other promises in the contract. For customer contracts with multiple performance obligations, the Company allocates revenue to each performance obligation based on its relative standalone selling price, which is generally determined based on standalone selling prices charged to customers or using expected cost plus margin. All of the Company's performance obligations, and associated revenue, are generally transferred to customers at a point in time, with the exception of certain highly customized pump products, which are transferred to the customer over time. The Company offers standard warranties for its products to ensure that its products comply with agreed-upon specifications in its contracts. For standard warranties, these do not give rise to performance obligations and represent assurance-type warranties. Shipping and handling activities related to products sold to customers, whether performed before or after the customer obtains control of the products, are generally accounted for as activities to fulfill the promise to transfer the products and not as a separate performance obligation. Contract Estimates Accounting for long-term contracts involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, the Company estimates the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract and recognizes that profit as performance obligations are satisfied. Contract estimates are based on various assumptions to project the outcome of future events that could span longer than one year. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials, and the performance of subcontractors as applicable. As a significant change in one or more of these estimates could affect the profitability of our contracts, the Company reviews and updates its contract-related estimates regularly. Adjustments in estimated profit on contracts are accounted for under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date on a contract is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance are recognized using the adjusted estimate. Contract Balances The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the Consolidated Balance Sheets. For certain highly customized pump products, revenue is recognized over time before the customer is invoiced, resulting in contract assets. Sometimes the Company receives advances or deposits from its customers before revenue is recognized, resulting in contract liabilities. These contract assets and liabilities are reported on the Consolidated Balance Sheets as a component of Other assets and Deferred revenue and customer deposits, respectively, on a contract-by-contract basis at the end of each reporting period. Income Taxes Income tax expense includes United States federal, state, local and international income taxes. Deferred tax assets and liabilities are recognized for the tax consequences of temporary differences between the financial reporting and the tax basis of existing assets and liabilities and for loss carryforwards. The tax rate used to determine the deferred tax assets and liabilities is the enacted tax rate for the year and manner in which the differences are expected to reverse. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized. The Company accounts for the global intangible low-taxed income (“GILTI”) tax in the period in which it is incurred. Pension and Other Postretirement Benefits The Company sponsors defined benefit pension plans covering certain domestic employees. Additionally, the Company sponsors defined contribution pension plans made available to all domestic and Canadian employees. The Company also sponsors a non-contributory defined benefit postretirement health care plan that provides health benefits to certain domestic and Canadian retirees and their spouses. The Company funds the cost of these benefits as incurred. The determination of the Company’s obligation and expense for pension and other postretirement benefits is dependent on its selection of certain assumptions used by actuaries in calculating such amounts, which are described in Note 10, Pensions and Other Postretirement Benefits. The Company recognizes the funded status of its defined benefit pension plan as an asset or liability in the Consolidated Balance Sheets and recognizes the change in the funded status in the year in which the change occurs through accumulated other comprehensive loss in the Consolidated Balance Sheets. Concentration of Credit Risk The Company generally does not require collateral from its customers and has a very good collection history. There were no Shipping and Handling Costs The Company classifies all amounts billed to customers for shipping and handling as revenue and reflects related shipping and handling costs in Cost of products sold. Advertising The Company expenses all advertising costs as incurred, which for the years ended December 31, 2022, 2021 and 2020 totaled $3.3 million, $1.9 million, and $2.1 million, respectively. Product Warranties A liability is established for estimated future warranty and service claims based on historical claims experience and specific product failures. The Company expenses warranty costs directly to Cost of products sold. Changes in the Company’s product warranty liability are: 2022 2021 2020 Balance at beginning of year $ 1,637 $ 1,361 $ 1,438 Provision 1,590 1,813 1,350 Acquired 646 - - Claims (1,900 ) (1,537 ) (1,427 ) Balance at end of year $ 1,973 $ 1,637 $ 1,361 Stock based compensation The Company awards shares pursuant to The Gorman-Rupp Company 2015 Omnibus Incentive Plan. Performance Stock Units (“PSU’s”) are typically conditioned upon achievement of appropriate performance metrics. PSU’s that have been granted will vest and be awarded at the end of a two three Foreign Currency Translation Assets and liabilities of the Company’s operations outside the United States which are accounted for in a functional currency other than U.S. dollars are translated into U.S. dollars using year-end exchange rates. Revenues and expenses are translated at weighted-average exchange rates effective during the year. Foreign currency translation gains and losses are included as a component of Accumulated other comprehensive loss within Equity. Gains and losses resulting from foreign currency transactions, the amounts of which are not material, are included in Other (expense) income, net. Fair Value The carrying value of Cash and cash equivalents, Accounts receivable and Accounts payable approximates fair value based on the short-term nature of these instruments. The carrying value of long term debt, including the current portion, approximates fair value as the variable interest rates approximate rates available to other market participants with comparable credit risk. The Company does not recognize any non-financial assets at fair value. Derivative Financial Instruments The Company uses interest rate swap agreements to partially reduce risks related to floating rate financing agreements that are subject to changes in the market rate of interest. Terms of the interest rate swap agreements require the Company to receive a variable interest rate and pay a fixed interest rate. The Company’s interest rate swap agreements and its variable rate financings are predominately based upon an Adjusted Term SOFR Rate. For cash flow hedges, the Company formally assesses, both at inception and on a quarterly basis thereafter, whether the designated derivative instrument is highly effective in offsetting changes in cash flows of the hedged item. Changes in the fair value of interest rate swap agreements that are effective as hedges are recorded in Accumulated Other Comprehensive Income (AOCI). Deferred gains or losses are reclassified from AOCI to the Consolidated Statements of Operations in the same period as the gains or losses from the underlying transactions are recorded and are generally recognized in interest expense. The Company discontinues hedge accounting prospectively when the derivative is not highly effective as a hedge, the underlying hedged transaction is no longer probable, or the hedging instrument expires, or is sold, terminated or exercised. Cash flows from hedging activities are reported in the Consolidated Statements of Cash Flows in the same classification as the hedged item, generally as a component of cash flows from operations.

Employees hired after this date, in eligible locations, participate in an enhanced 401(k) plan instead of the defined benefit pension plan. Employees hired prior to this date continue to accrue benefits. Additionally, the Company sponsors defined contribution pension plans made available to all domestic and Canadian employees. Total contributions to the plans were $3.0 million for 2022 and $2.3 million for each of 2021 and 2020.

The Company also sponsors a non-contributory defined benefit postretirement health care plan that provides health benefits to certain domestic and Canadian retirees and eligible spouses and dependent children. The Company funds the cost of these benefits as incurred. For measurement purposes, and based on maximum benefits as defined by the plan, a 5% annual rate of increase in the per capita cost of covered health care benefits for all retirees was assumed in estimating the projected postretirement benefit obligation at December 31, 2022, which is expected to remain constant going forward. A 5% percent annual rate of increase was assumed in estimating the projected benefit obligation at December 31, 2021 and in calculating 2022 periodic benefit cost. The Company recognizes the obligations associated with its defined benefit pension plans and defined benefit postretirement health care plan in its Consolidated Financial Statements. The following table presents the plans’ funded status as of the measurement date, December 31, reconciled with amounts recognized in the Company’s Consolidated Balance Sheets: Pension Plans Postretirement Plan 2022 2021 2022 2021 Accumulated benefit obligation at end of year $ 45,756 $ 67,400 $ 23,954 $ 28,934 Change in projected benefit obligation: Benefit obligation at beginning of year $ 82,000 $ 86,299 $ 28,934 $ 29,848 Service cost 2,400 2,662 1,146 1,462 Interest cost 2,326 1,729 760 654 Settlement 1,656 651 - - Benefits paid (17,826 ) (7,719 ) (1,781 ) (1,618 ) Effect of foreign exchange - - (28 ) 1 Actual expenses (150 ) (150 ) - - Actuarial (gain)/ loss (14,454 ) (1,472 ) (5,077 ) (1,413 ) Benefit obligation at end of year $ 55,952 $ 82,000 $ 23,954 $ 28,934 Change in plan assets: Plan assets at beginning of year $ 72,658 $ 77,067 $ - $ - Actual return on plan assets (10,332 ) 1,460 - - Employer contributions 2,250 2,000 1,781 1,618 Benefits paid (17,826 ) (7,719 ) (1,781 ) (1,618 ) Actual expenses (150 ) (150 ) - - Plan assets at end of year $ 46,600 $ 72,658 $ - $ - Funded status at end of year $ (9,352 ) $ (9,342 ) $ (23,954 ) $ (28,934 ) Pension Plans Postretirement Plan 2022 2021 2022 2021 Amounts recognized in the Consolidated Balance Sheets consist of: Current liabilities $ - $ - $ (1,541 ) $ (1,575 ) Noncurrent liabilities (9,352 ) (9,342 ) (22,413 ) (27,359 ) Total assets (liabilities) $ (9,352 ) $ (9,342 ) $ (23,954 ) $ (28,934 ) Amounts recognized in Accumulated other Net actuarial loss $ 18,290 $ 26,016 $ 308 $ 5,841 Prior Service Cost - - (995 ) (2,125 ) Deferred tax (benefit) expense (4,607 ) (6,446 ) 242 (807 ) After tax actuarial loss $ 13,683 $ 19,570 $ (445 ) $ 2,909 Components of net periodic benefit cost: 2022 2021 2020 Pension Plans Service cost $ 2,400 $ 2,662 $ 2,709 Interest cost 2,326 1,729 1,937 Expected return on plan assets (2,892 ) (3,610 ) (3,900 ) Recognized actuarial loss 1,724 1,904 2,160 Settlement loss 6,427 2,304 4,583 Net periodic benefit cost $ 9,985 $ 4,989 $ 7,489 Other changes in pension plan assets and benefit obligations recognized in other comprehensive loss: Net (gain) loss (7,726 ) (2,879 ) 2,704 Total expense recognized in net periodic benefit cost and other comprehensive income $ 2,259 $ 2,110 $ 10,193 Postretirement Plan Service cost $ 1,146 $ 1,462 $ 1,372 Interest cost 760 654 778 Prior service cost recognition (1,128 ) (1,130 ) (1,129 ) Recognized actuarial loss (gain) 368 580 306 Net periodic benefit cost (credit) $ 1,146 $ 1,566 $ 1,327 Other changes in postretirement plan assets and benefit obligations recognized in other comprehensive loss: Net loss (gain) $ (4,317 ) $ (863 ) $ 3,762 Total expense (benefit) recognized in net periodic benefit cost and other comprehensive income $ (3,171 ) $ 703 $ 5,089 The components of net periodic benefit cost other than the service cost component are included in Other income (expense), net in the Consolidated Statements of Income. During 2022, 2021, and 2020, the Company recorded a settlement loss relating to retirees that received lump-sum distributions from the GR Plan totaling $6.4 million, $2.3 million and $4.6 million respectively. These charges were the result of lump-sum payments to retirees which exceeded the GR Plan’s actuarial service and interest cost thresholds. The prior service cost is amortized on a straight-line basis over the average estimated remaining service period of active participants. The unrecognized actuarial gain or loss in excess of the greater of 10% of the benefit obligation or the market value of plan assets is also amortized on a straight-line basis over the average estimated remaining service period of active participants. Pension Plans Postretirement Plan 2022 2021 2022 2021 Weighted-average assumptions used to determine benefit obligations at December 31: Discount rate 4.89 % 2.44 % 5.16 % 2.70 % Rate of compensation increase 3.50 % 3.50 % - - Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31: Discount rate 4.43 % 2.07 % 2.70 % 2.25 % Expected long-term rate of return on plan assets 5.00 % 5.10 % - – Rate of compensation increase 3.50 % 3.50 % - – To enhance the Company’s efforts to mitigate the impact of the defined benefit pension plan on its financial statements, in 2014 the Company moved towards a liability driven investing model to more closely align assets with liabilities based on when the liabilities are expected to come due. Currently, based on 2022 funding levels, equities may comprise between 22% and 42% of the Plan’s market value. Fixed income investments may comprise between 50% and 70% of the GR Plan’s market value. Alternative investments may comprise between 3% and 13% of the Plan’s market value. Cash and cash equivalents (including all senior debt securities with less than one year to maturity) may comprise between 0% and 10% of the GR Plan’s market value. Financial instruments included in pension plan assets are categorized into a fair value hierarchy of three levels, based on the degree of subjectivity inherent in the valuation methodology. Level 1 assets are based on unadjusted quoted prices in active markets that are accessible to the reporting entity at the measurement date for identical assets. Level 2 assets are valued at inputs other than quoted prices in active markets for identical assets that are observable either directly or indirectly for substantially the full term of the assets. Level 3 assets are valued based on unobservable inputs for the asset (i.e., supported by little or no market activity). These inputs include management’s own assessments about the assumptions that market participants would use in pricing assets (including assumptions about risk). The level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The following tables set forth by asset class the fair value of plan assets for the years ended December 31, 2022 and 2021: Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Plan Assets at December 31, 2022 Equity $ 7,157 $ - $ - $ 7,157 Fixed income 5,052 27,045 - 32,097 Mutual funds 2,406 - - 2,406 Money funds and cash 1,527 3,413 - 4,940 Total fair value of Plan assets $ 16,142 $ 30,458 $ - $ 46,600 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Plan Assets at December 31, 2021 Equity $ 10,979 $ - $ - $ 10,979 Fixed income 8,788 42,154 139 51,081 Mutual funds 3,045 - - 3,045 Money funds and cash 2,220 5,333 - 7,553 Total fair value of Plan assets $ 25,032 $ 47,487 $ 139 $ 72,658 Contributions The Company expects to contribute up to $2.3 million to its defined benefit pension plans in 2023. Expected future benefit payments The following benefit payments are expected to be paid as follows based on actuarial calculations: 2023 2024 2025 2026 2027 Thereafter Pension $ 7,435 $ 2,930 $ 3,272 $ 2,871 $ 3,838 $ 25,710 Postretirement 1,580 1,591 1,632 1,673 1,750 10,356 For measurement purposes, and based on maximum benefits as defined by the plan, a 5% annual rate of increase in the per capita cost of covered health care benefits for all retirees was assumed as of December 31, 2022 and 2021 and is expected to remain constant going forward . A one percentage point change in the assumed rate of return on the defined benefit pension plans assets is estimated to have an approximate $0.6 million effect on net periodic benefit cost. Additionally, a one percentage point increase in the discount rate is estimated to have a $1.7 million decrease in net periodic benefit cost, while a one percentage point decrease in the discount rate is estimated to have a $2.0million increase in net periodic benefit cost.

The following table summarizes the future estimated amortization expense relating to our intangible assets as of December 31, 2022 (in thousands): 2023 2024 2025 2026 2027 Thereafter Total $ 12,527 $ 12,402 $ 12,367 $ 12,318 $ 12,281 $ 174,240 $ 236,135 For 2022, the Company used a quantitative analysis for the annual goodwill impairment testing as of October 1 for its National Pump Company (“National”) reporting unit. The fair value for this reporting unit was estimated using both a discounted cash flow model and a market-based approach. The discounted cash flow model considered forecasted cash flows discounted at an estimated weighted-average cost of capital. The forecasted cash flows were based on the Company’s long-term operating plan and a terminal value was used to estimate the cash flows beyond the period covered by the operating plan. The weighted-average cost of capital is an estimate of the overall after-tax rate of return required by equity and debt market holders of a business enterprise. The market-based approach considers market prices of corporations engaged in the same or similar line of business. These analyses require the exercise of significant judgments, including judgments about appropriate discount rates, perpetual growth rates and the timing of expected future cash flows. Sensitivity analyses were performed around these assumptions in order to assess the reasonableness of the assumptions and the resulting estimated fair values. The result of this goodwill impairment test indicated that no impairment existed at National. The Company’s annual impairment analysis performed as of October 1, 2022 concluded that National’s fair value exceeded its carrying value. A sensitivity analysis was performed for the National reporting unit, assuming a hypothetical 100 basis point decrease in the expected long-term growth rate or a hypothetical 100 basis point increase in the weighted average cost of capital, and both scenarios independently yielded an estimated fair value for the National reporting unit above carrying value. If National fails to experience growth or revises its long-term projections downward, it could be subject to impairment charges in the future. Goodwill relating to the National reporting unit is $13.6 million, 1.6% of the Company’s December 31, 2022 total assets. For 2022, for all other reporting units, the Company used a qualitative analysis for goodwill impairment testing as of October 1. This qualitative assessment included consideration of current industry and market conditions and circumstances as well as any mitigating factors that would most affect the fair value of the Company and these reporting units. Based on the assessment and consideration of the totality of the facts and circumstances, including the business environment in the fourth quarter of 2022, the Company determined that it was not more likely than not that the fair value of the Company or these reporting units is less than their respective carrying amounts. As such, no goodwill impairments for these reporting units were recorded for the year ended December 31, 2022. Other indefinite-lived intangible assets primarily consist of trademarks and trade names. The fair value of these assets is also tested annually for impairment as of October 1, or whenever events or changes in circumstances indicate there may be a possible permanent loss of value. The fair value of these assets is determined using a royalty relief methodology similar to that employed when the associated assets were acquired, but using updated estimates of future sales, cash flows and profitability. For 2022 and 2021 the fair value of all indefinite lived intangible assets exceeded the respective carrying values. Finite-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount may not be recovered through future net cash flows generated by the assets. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to future net undiscounted cash flows estimated to be generated by such assets. Based upon our fiscal 2022 and 2021 quantitative and qualitative impairment analyses the Company was not aware of any events or changes in circumstances that indicate the carrying value of its finite-lived intangible assets may not be recoverable.
