Basis of presentation	Note 1. Basis of presentation The interim unaudited condensed consolidated financial statements of Mayville Engineering Company, Inc. and subsidiaries (MEC, the Company, we, our, us or similar terms) presented here have been prepared in accordance with the accounting principles generally accepted in the United States of America (GAAP) and with instructions to Form 10-Q and Article 10 of Regulation S-X. They reflect all adjustments which are, in the opinion of management, necessary for a fair presentation of the results of operations and financial position for the interim unaudited periods presented. All intercompany balances and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. These interim unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto for the year ended December 31, 2021, included in the Company’s Annual Report on Form 10-K. A summary of the Company’s significant accounting policies is included in the Company’s 2021 financial statements in the Annual Report on Form 10-K. The Company followed these policies in preparation of the interim unaudited Condensed Consolidated Financial Statements except for new accounting pronouncements adopted as described below. Nature of Operations MEC is a leading U.S.-based value-added manufacturing partner that provides a broad range of prototyping and tooling, production fabrication, coating, assembly and aftermarket components.

Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases annual reporting guidance as of January 1, 2022 using the effective date approach. The Company early adopted the interim reporting guidance during the period ended March 31, 2022. The new guidance provides a number of optional practical expedients in transition. The Company elected the "package of practical expedients", which allows it to not reassess under the new guidance its prior conclusions about lease identification, lease classification and initial direct costs. The Company did not elect the use-of-hindsight practical expedient. In addition, the new guidance provides accounting policy elections for an entity’s ongoing lessee accounting. The Company has elected to not separate lease and non-lease components for certain of its real estate leases. The Company has elected the short-term lease recognition exemption for all leases that qualify which means that it will not recognize ROU assets or lease liabilities for those leases with a term of 12 months or less. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments Financial Instruments – Credit Losses In December 2019, the FASB issued ASU 2019-12, Income Taxes A summary of the Company’s evaluation of other recent accounting pronouncements is included in the Company’s 2021 financial statements in its Annual Report on Form 10-K for the year ended December 31, 2021.

Select Balance Sheet Data [Abstract]
Select balance sheet data	Note 2. Select balance sheet data Inventory Inventories are stated at the lower of cost, determined on the first-in, first-out method and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Work-in-process and finished goods are valued at production costs consisting of material, labor, and overhead. Inventories as of June 30, 2022 and December 31, 2021 consist of: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2022 2021 Finished goods and purchased parts ​ $ 42,828 ​ $ 41,041 Raw materials ​ 19,500 ​ 18,905 Work-in-process ​ 11,775 ​ 10,211 Total ​ $ 74,103 ​ $ 70,157 ​ At December 31, 2021, there was uncertainty as to the level of demand from the former fitness customer. The Company received a notification from this customer in February 2022 resulting in a change in forecasted future cash flow, triggering an impairment assessment of assets purchased, and assets the Company had committed to purchase, to meet obligations under the agreement with the former fitness customer as of December 31, 2021. As a result, at December 31, 2021, the Company recorded an inventory impairment of $700, of which $661 was due to loss contacts recorded in other current liabilities and a $39 decrease to inventories. As of June 30, 2022, there was a balance of Property, plant and equipment Property, plant and equipment as of June 30, 2022 and December 31, 2021 consist of: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Useful Lives June 30, December 31, ​ ​ Years ​ 2022 ​ 2021 Land ​ ​ Indefinite ​ $ 1,033 ​ $ 1,033 Land improvements ​ ​ 15-39 ​ ​ 3,169 ​ ​ 3,169 Building and building improvements ​ 15-39 ​ 57,971 ​ 56,243 Machinery, equipment and tooling ​ 3-10 ​ 230,803 ​ 222,202 Vehicles ​ 5 ​ 3,947 ​ 3,943 Office furniture and fixtures ​ 3-7 ​ 18,785 ​ 17,960 Construction in progress ​ N/A ​ 22,919 ​ 15,443 Total property, plant and equipment, gross ​ ​ ​ ​ 338,627 ​ 319,993 Less accumulated depreciation ​ ​ ​ ​ 209,118 ​ 199,247 Total property, plant and equipment, net ​ ​ ​ ​ $ 129,509 ​ $ 120,746 ​ Depreciation expense was $5,507 and $5,161 for the three months ended June 30, 2022 and 2021, respectively, and $10,975 and $10,236 for the six months ended June 30, 2022 and 2021, respectively. At December 31, 2021, there was uncertainty as to the level of demand from the former fitness customer. The Company received a notification from the former fitness customer in February 2022 resulting in a change in forecasted future cash flow, triggering an impairment assessment of assets purchased, and assets the Company had committed to purchase, to meet obligations under the agreement with the former fitness customer as of December 31, 2021. As a result, at December 31, 2021, the Company recorded a long-lived asset impairment $12,875. During the three and six months ended June 30, 2022, the Company was able to cancel $906 and $2,089, respectively, of purchase commitments for property, plant and equipment relating to the former fitness customer that had previously been recorded in the Condensed Consolidated Statements of Comprehensive Income as an impairment of long-lived assets and loss on contracts as of December 31, 2021. The cancellation of loss contracts has resulted in the reversal of this amount from other current liabilities in the Condensed Consolidated Balance Sheets and recorded in the Condensed Consolidated Statements of Comprehensive Income as an impairment of long-lived assets and gain on contracts for the current period. Throughout the three months ended June 30, 2022, the Company sold $4,971 of machinery and equipment originally intended to support production for the former fitness customer, resulting in a gain on sale of the assets of $520, which is classified in cost of sales on the Condensed Consolidated Statements of Comprehensive Income as of June 30, 2022. As a result of the previously mentioned impairment, these assets had been written down to fair value as of December 31, 2021. As of June 30, 2022, $1,288 of property, plant and equipment has been reclassified within the Condensed Consolidated Balance Sheets as assets held for sale. The Company adopted ASC 842 on January 1, 2022, classifying finance leases of $981 in property, plant and equipment on the Condensed Consolidated Balance Sheets as of June 30, 2022. Please refer to Note 4 – Leases for additional information.

Debt Disclosure [Abstract]
Bank revolving credit notes	Note 3. Bank revolving credit notes On September 26, 2019, and as last amended on March 31, 2022, we entered into an amended and restated credit agreement (Credit Agreement) with certain lenders and Wells Fargo Bank, National Association, as administrative agent (the Agent). The Credit Agreement provides for a $200,000 revolving credit facility (the Revolving Loan), with a letter of credit sub-facility in an aggregate amount not to exceed $5,000, and a swingline facility in an aggregate amount of $20,000. The Credit Agreement also provides for an additional $100,000 of debt capacity through an accordion feature. All amounts borrowed under the Credit Agreement mature on September 26, 2024. The Credit Agreement contains usual and customary negative covenants for agreements of this type, including, but not limited to, restrictions on our ability to, subject to certain exceptions, create, incur or assume indebtedness, create or incur liens, make certain investments, merge or consolidate with another entity, make certain asset dispositions, pay dividends or other distributions to shareholders, enter into transactions with affiliates, enter into sale leaseback transactions or make capital expenditures. The Credit Agreement also requires us to satisfy certain financial covenants, including a minimum interest coverage ratio of 3.00 to 1.00 as well as a consolidated total leverage ratio not to exceed 3.25 to 1.00, although such leverage ratio can be increased in connection with certain acquisitions. In order to provide a means of insurance against future macroeconomic events, we entered into an amendment (Second Amendment) to the Credit Agreement on June 30, 2020. The Second Amendment provided the Company with temporary changes to the total leverage ratio covenant for the period from June 30, 2020, through December 31, 2021, or such earlier date as the Company may elect (Covenant Relief Period), in return for certain increases in interest rates, fees and restrictions on certain activities of the Company, including capital expenditures, acquisitions, dividends and share repurchases. New pricing, which took effect for the quarters ending on and after September 30, 2020, includes interest at a fluctuating London Interbank Offered Rate (LIBOR) (at a floor of 75 basis points), plus 1.00% to 2.75%, along with the commitment fee ranging from 20 to 50 basis points. During the Covenant Relief Period, the required ceiling on the Company’s total leverage ratio was 4.25 to 1.00 for quarters ending June 30, 2020 through and including December 31, 2020, and declined in quarterly increments to 3.25 to 1.00 through the quarter ending December 31, 2021. We entered into an amendment (Third Amendment) to the Credit Agreement on March 31, 2021 which allowed the Company to incur up to $70,000 of capital expenditures in 2021, as opposed to $35,000. We entered into an amendment (Fourth Amendment) to the Credit Agreement on March 31, 2022 which allows the Company to incur up to $65,000 of capital expenditures in 2022, as opposed to $35,000, and revises the definition of Consolidated EBITDA to include certain restructuring and impairment charges. At June 30, 2022, our consolidated total leverage ratio was 1.52 to 1.00 as compared to a covenant maximum of 3.25 to 1.00 in accordance with the Credit Agreement. At June 30, 2022, our interest coverage ratio was 18.34 to 1.00 as compared to a covenant minimum of 3.00 to 1.00 under the Credit Agreement. Under the Credit Agreement, interest is payable quarterly at the adjusted LIBOR plus an applicable margin based on the current funded indebtedness to adjusted EBITDA ratio. The interest rate was 2.06% and 1.75% as of June 30, 2022 and December 31, 2021, respectively. Additionally, the agreement has a fee on the average daily unused portion of the aggregate unused revolving commitments. This fee was 0.20% as of June 30, 2022 and December 31, 2021. The Company was in compliance with all financial covenants of its credit agreements as of June 30, 2022 and December 31, 2021. The amount borrowed on the revolving credit notes was $76,063 and $67,610 as of June 30, 2022 and December 31, 2021, respectively.

The most significant judgements and impacts related to the application of the new guidance include the following: ● In evaluating contracts to determine if they qualify as a lease, the Company considers factors such as if the Company has obtained or transferred substantially all of the rights to the underlying asset through exclusivity, if the Company can transfer or has transferred the ability to direct the use of the asset by making decisions about how and for what purpose the asset will be used and if the lessor has substantive substitution rights. ● The Company made judgements regarding lease terms for certain of its leases that were in month-to-month status or that contained auto-renewal clauses. The Company estimated a lease end date based on the required length of usage of the property and calculated a ROU asset and lease liability based on the resulting estimated lease term. ● The Company has recognized ROU assets and lease liabilities for operating leases that have not previously been recorded. The lease liability for operating leases is based on the net present value of future minimum lease payments. ● The ROU asset for operating leases is based on the initial calculated lease liability as adjusted for the reclassification of certain balance sheet amounts such as deferred rent. ● In determining the discount rate used to measure the ROU assets and lease liabilities, the Company uses the rate implicit in the lease, or if not readily available, the Company uses the Company’s incremental borrowing rate. The base rate used to establish the Company’s incremental borrowing rate is based on a Prime Rate (or LIBOR fallback option) plus fixed basis points methodology pursuant to the Company’s revolving credit facility (as amended from time to time). Certain required adjustments were then made to this base rate to arrive at an estimated incremental borrowing rate. ● The Company’s real property leases vary in terms of up to ten years , including options for renewal periods that are considered reasonably certain to be exercised. The Company’s personal property leases vary in terms of up to seven years , including options for renewal periods that are considered reasonably certain to be exercised. ● Upon adoption of the new guidance at January 1, 2022, the Company established a ROU asset of $37,908 and a lease liability of $38,185 related to its real property operating leases and established a ROU asset of $2,415 and a lease liability of $2,418 related to its personal property operating leases. Additionally, the impact on retained earnings was immaterial. The January 1, 2022, balances associated with the Company’s personal property finance leases will be reclassified in the financial statements from capital lease, net to property, plant and equipment, net, from current portion of capital lease obligation to other current liabilities, and from capital lease obligation, less current maturities to other long-term liabilities on the Condensed Consolidated Balance Sheets. The Company has real property operating leases for office and light manufacturing space. Operating leases for the Company’s personal property consist of leases for office equipment, vehicles, forklifts and storage tanks for bulk gases. The Company recognizes a ROU asset and a lease liability for operating leases based on the net present value of future minimum lease payments. Lease expense for the Company’s operating leases is recognized on a straight-line basis over the lease term, including renewal periods that are considered reasonably certain. The Company has finance leases for two laser cutting systems and a vehicle. The Company recognizes a ROU asset and a lease liability for finance leases based on the net present value of future minimum lease payments. Lease expense for the Company’s finance leases is comprised of the amortization of the ROU asset and interest expense recognized based on the effective interest method. Variable lease expense is related to certain of the Company’s real property leases and personal property leases, and it generally consists of property tax and insurance components that are for the benefit of the lessor (real property leases) and variable overage fees (personal property leases) that are remitted as part of the Company’s lease payments. The components of lease expense were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Six Months Ended ​ June 30, 2022 ​ June 30, 2022 Finance lease cost: ​ ​ ​ ​ ​ ​ Amortization of finance lease assets ​ $ 78 ​ $ 157 Interest on finance lease liabilities ​ ​ 11 ​ 22 Total finance lease expense ​ ​ 89 ​ ​ 179 Operating lease expense ​ ​ 1,512 ​ ​ 3,034 Short-term lease expense ​ ​ 139 ​ ​ 318 Variable lease expense ​ ​ 61 ​ 108 Sublease income (1) ​ ​ (146) ​ ​ (146) Total lease expense ​ $ 1,655 ​ $ 3,493 (1) The Company subleased a portion of its Hazel Park, MI facility starting in June 2022.

Income Tax Disclosure [Abstract]
Income taxes	Note 7. Income taxes On a quarterly basis, the Company estimates its effective tax rate for the full fiscal year and records a quarterly income tax provision based on the anticipated rate. As the year progresses, the Company will refine its estimate based on facts and circumstances by each tax jurisdiction. Income tax expense was $1,798 and $2,974, and the effective tax rate (ETR) was 23.27% and 23.37% for the three and six months ended June 30, 2022, respectively. Our ETR is different from the expected tax rate due to state taxes, non-deductible items, research and development credits and benefit from excess tax deductions related to share based compensation items. For the three and six months ended June 30, 2021, income tax expense was estimated at $1,007 and $1,996 and the ETR was 23.43% and 25.48%, respectively. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in these jurisdictions. ASC 740, Income Taxes The Company’s policy for recording interest and penalties associated with potential income tax audits is to record such expense as a component of income tax expense. There were no amounts for penalties or interest recorded as of June 30, 2022. Management is currently unaware of any issues under review that could result in significant payments, accruals or material deviations from its positions. Uncertain Tax Positions Based on the Company’s evaluation, it has been concluded that there is one tax position related to the research and development tax credit requiring recognition in the Company’s financial statements as of June 30, 2022. The Company does not anticipate that there will be a material change in the balance of the unrecognized tax benefits in the next 12 months. Any interest and penalties related to uncertain tax positions are recorded in income tax expense. No amounts have been recorded as tax expense for interest and penalties for the three and six months ended June 30, 2022, as the amount for the utilized portion for the research and development credit on the Wisconsin return is considered to be immaterial. At June 30, 2022 and December 31, 2021, a total of $394 and $314, respectively, of unrecognized tax benefits would, if recognized, impact the Company’s ETR. The Company files income tax returns in the United States federal jurisdiction and in various state and local jurisdictions. Federal tax returns for tax years beginning January 1, 2018, and state tax returns beginning January 1, 2017, are open for examination.

Deferred Compensation Liability [Abstract]
Deferred compensation	Note 9. Deferred compensation The Mayville Engineering Deferred Compensation Plan is available for certain employees designated to be eligible to participate by the Company and approved by the Board of Directors. Eligible employees may elect to defer a portion of his or her compensation for any plan year and the deferral cannot exceed 50% of the participant’s base salary and may include the participant’s annual short-term cash incentive up to 100%. The participant’s election must be made prior to the first day of the plan year. An employer contribution will be made for each participant to reflect the amount of any reduced allocations to the ESOP and/or 401(k) employer contributions due solely to the participant’s deferral amounts, as applicable. In addition, a discretionary amount may be awarded to a participant by the Company. Deferrals are assumed to be invested in an investment vehicle based on the options made available to the participant (which does not include Company stock). The deferred compensation plan provides benefits payable upon separation of service or death. Payments are to be made 30 days after date of separation from service, either in a lump-sum payment or up to five annual installments as elected by the participant when the participant first elects to defer compensation. The deferred compensation plan is non-funded, and all future contributions are unsecured in that the employees have the status of a general unsecured creditor of the Company and the agreements constitute a promise by the Company to make benefit payments in the future. During the three and six months ended June 30, 2022 and 2021, eligible employees elected to defer compensation of $0. As of June 30, 2022 and December 31, 2021, the short-term portion accrued for all benefit years less than 12 months under this plan was $17,531 and $0, respectively. As of June 30, 2022 and December 31, 2021, the long-term portion accrued for all benefit years greater than 12 months under this plan was $2,949 and $25,117. These amounts include the initial deferral of compensation as adjusted for (a) subsequent changes in the share value of the Company stock or (b) in the investment options chosen by the participants. Total expense (credit) for the deferred compensation plan for the three months ended June 30, 2022 and 2021 was $(2,461) and $575, respectively. Total expense (credit) for the deferred compensation plan for the six months ended June 30, 2022 and 2021 amounted to $(3,589) and $405, respectively. These expenses (credits) are included in profit sharing, bonuses and deferred compensation on the Condensed Consolidated Statements of Comprehensive Income. Additionally, the Company made distributions of $1,048 and $575 for the six months ended June 30, 2022 and 2021, respectively.

Fair Value Disclosures [Abstract]
Fair value of financial instruments	Note 12. Fair value of financial instruments Fair value provides information on what the Company may realize if certain assets were sold or might pay to transfer certain liabilities based upon an exit price. Financial assets and liabilities that are measured and reported at fair value are classified into a three-level hierarchy that prioritizes the inputs used in the valuation process. A financial instrument’s categorization within the valuation hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The hierarchy is based on the observability and objectivity of the pricing inputs as follows: ● Level 1 – Quoted prices in active markets for identical assets or liabilities. ● Level 2 – Significant directly observable data (other than Level 1 quoted prices) or significant indirectly observable data through corroboration with observable market data. Inputs would normally be (i) quoted prices in active markets for similar assets or liabilities, (ii) quoted prices in inactive markets for identical or similar assets or liabilities or (iii) information derived from or corroborated by observable market data. Long-term debt is classified as a Level 2 fair value input. ● Level 3 – Prices or valuation techniques that require significant unobservable data inputs. These inputs would normally be the Company’s own data and judgements about assumptions that market participants would use in pricing the asset or liability. The following table lists the Company’s financial assets and liabilities accounted for at fair value by the fair value hierarchy: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance at ​ Fair Value Measurements at ​ ​ June 30, ​ Report Date Using ​ 2022 (Level 1) (Level 2) (Level 3) Deferred compensation liability ​ $ 20,480 ​ $ 20,480 ​ $ — ​ $ — Total ​ $ 20,480 ​ $ 20,480 ​ $ — ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance at ​ Fair Value Measurements at ​ ​ December 31, ​ Report Date Using ​ 2021 (Level 1) (Level 2) (Level 3) Deferred compensation liability ​ $ 25,117 ​ $ 22,272 ​ $ 2,845 ​ $ — Total ​ $ 25,117 ​ $ 22,272 ​ $ 2,845 ​ $ — ​ Fair value measurements for the Company’s cash and cash equivalents are classified based upon Level 1 measurements because such measurements are based upon quoted market prices in active markets for identical assets. Accounts receivable, accounts payable, long-term debt and accrued liabilities are recorded in the Condensed Consolidated Balance Sheets at cost and approximate fair value. Deferred compensation liabilities are recorded at amounts due to participants at the time of deferral. Deferrals are invested in an investment vehicle based on the options made available to the participant, considered to be Level 1 and Level 2 on the fair value hierarchy, with the current balance as Level 1. The change in fair value is recorded in the profit sharing, bonuses, and deferred compensation line item on the Condensed Consolidated Statements of Comprehensive Income. The short-term and long-term balances due to participants are reflected on the current portion of deferred compensation and deferred compensation, less current portion, line items, respectively, on the Condensed Consolidated Balance Sheets. The Company’s non-financial assets such as goodwill, intangible assets and property, plant, and equipment are re-measured at fair value when there is an indication of impairment and adjusted only when an impairment charge is recognized.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	Note 14. Revenue Recognition Contract Assets and Contract Liabilities The Company has contract assets and contract liabilities, which are included in tooling in progress and other current liabilities on the Condensed Consolidated Balance Sheets, respectively. Contract assets include products where the Company has satisfied its performance obligation, but receipt of payment is contingent upon delivery. Contract liabilities include deferred tooling revenue, where the performance obligation was not met. The performance obligation is satisfied when the tooling is completed and the customer signs off through the Product Part Approval Process (PPAP). Cost of goods sold is recognized and released from the balance sheet when control of the tooling promised under contract is transferred to the customer. The Company’s contracts with customers are short-term in nature; therefore, revenue is typically recognized, billed and collected within a 12-month period. The following table reflects the changes in our contract assets and liabilities during the six months ended June 30, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contract ​ Contract ​ Assets Liabilities As of December 31, 2021 ​ $ 3,950 ​ $ 2,718 Net activity ​ ​ 1,367 ​ ​ 2,598 As of June 30, 2022 ​ $ 5,317 ​ $ 5,316 ​ Disaggregated Revenue The following table represents a disaggregation of revenue by product category: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Six Months Ended ​ ​ ​ June 30, ​ June 30, ​ ​ 2022 2021 2022 2021 ​ Outdoor sports ​ $ 2,522 ​ $ 3,006 ​ $ 5,049 ​ $ 5,677 ​ Fabrication ​ ​ 83,038 ​ ​ 78,318 ​ ​ 165,271 ​ ​ 147,689 ​ Performance structures ​ ​ 28,197 ​ ​ 18,753 ​ ​ 57,157 ​ ​ 39,208 ​ Tube ​ ​ 19,488 ​ ​ 15,760 ​ ​ 37,796 ​ ​ 30,647 ​ Tank ​ ​ 8,915 ​ ​ 5,622 ​ ​ 17,464 ​ ​ 12,413 ​ Total ​ ​ 142,160 ​ ​ 121,459 ​ ​ 282,737 ​ ​ 235,634 ​ Intercompany sales elimination ​ ​ (3,823) ​ ​ (1,246) ​ ​ (8,148) ​ ​ (2,801) ​ Total, net sales ​ $ 138,337 ​ $ 120,213 ​ $ 274,589 ​ $ 232,833 ​ ​

Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases annual reporting guidance as of January 1, 2022 using the effective date approach. The Company early adopted the interim reporting guidance during the period ended March 31, 2022. The new guidance provides a number of optional practical expedients in transition. The Company elected the "package of practical expedients", which allows it to not reassess under the new guidance its prior conclusions about lease identification, lease classification and initial direct costs. The Company did not elect the use-of-hindsight practical expedient. In addition, the new guidance provides accounting policy elections for an entity’s ongoing lessee accounting. The Company has elected to not separate lease and non-lease components for certain of its real estate leases. The Company has elected the short-term lease recognition exemption for all leases that qualify which means that it will not recognize ROU assets or lease liabilities for those leases with a term of 12 months or less. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments Financial Instruments – Credit Losses In December 2019, the FASB issued ASU 2019-12, Income Taxes A summary of the Company’s evaluation of other recent accounting pronouncements is included in the Company’s 2021 financial statements in its Annual Report on Form 10-K for the year ended December 31, 2021.
