The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. Accordingly, these statements do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, the accompanying condensed consolidated financial statements include all normal recurring adjustments necessary for their fair presentation in accordance with GAAP. All significant intercompany balances and transactions have been eliminated. Interim results are not necessarily indicative of results for a full year.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The accounting guidance for fair value measurements establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value: • Level 1 – Quoted prices in active markets for identical assets or liabilities. • Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. As a result of our pension termination and settlement efforts in late 2019 and the first half of 2020, we had a pension surplus investment balance, which was accounted for as an available-for-sale investment as of June 2020. At the end of April, 2022, the entirety of the balance was paid out as a one-time discretionary contribution to all participants of the Rogers Employees Savings Investment Plan. For additional information regarding this balance, refer to “Note 11 – Pension Benefits and Other Postretirement Benefits.” Available-for-sale investments measured at fair value on a recurring basis, categorized by the level of inputs used in the valuation, were as follows: Available-for-Sale Investment at Fair Value as of June 30, 2022 (Dollars in thousands) Level 1 Level 2 Level 3 Total Pension surplus investment (1) $ — $ — $ — $ — Available-for-Sale Investment at Fair Value as of December 31, 2021 (Dollars in thousands) Level 1 Level 2 Level 3 Total Pension surplus investment (1) $ 6,638 $ — $ — $ 6,638 (1) This balance was invested in funds comprised of short-term cash and fixed income securities, and was recorded in the “Other long-term assets” line item in the condensed consolidated statements of financial position as of December 31, 2021. The fair value of these investments approximated its carrying value as of December 31, 2021. From time to time we enter into various instruments that require fair value measurement, including foreign currency contracts and copper derivative contracts. Derivative instruments measured at fair value on a recurring basis, categorized by the level of inputs used in the valuation, were as follows: Derivative Instruments at Fair Value as of June 30, 2022 (Dollars in thousands) Level 1 Level 2 Level 3 Total (1) Foreign currency contracts $ — $ (130) $ — $ (130) Copper derivative contracts $ — $ 181 $ — $ 181 Derivative Instruments at Fair Value as of December 31, 2021 (Dollars in thousands) Level 1 Level 2 Level 3 Total (1) Foreign currency contracts $ — $ (16) $ — $ (16) Copper derivative contracts $ — $ 1,344 $ — $ 1,344 (1) All balances were recorded in the “Other current assets” or “Other accrued liabilities” line items in the condensed consolidated statements of financial position.

Hedging Transactions and Deriva

Hedging Transactions and Derivative Financial Instruments	6 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Hedging Transactions and Derivative Financial Instruments	Hedging Transactions and Derivative Financial Instruments We are exposed to certain risks related to our ongoing business operations. The primary risks being managed through our use of derivative instruments are foreign currency exchange rate risk and commodity pricing risk (primarily related to copper). We do not use derivative instruments for trading or speculative purposes. The valuation of derivative contracts used to manage each of these risks is described below: • Foreign Currency – The fair value of any foreign currency option derivative is based upon valuation models applied to current market information such as strike price, spot rate, maturity date and volatility, and by reference to market values resulting from an over-the-counter market or obtaining market data for similar instruments with similar characteristics. • Commodity – The fair value of copper derivatives is computed using a combination of intrinsic and time value valuation models, which are collectively a function of five primary variables: price of the underlying instrument, time to expiration, strike price, interest rate and volatility. The intrinsic valuation model reflects the difference between the strike price of the underlying copper derivative instrument and the current prevailing copper prices in an over-the-counter market at period end. The time value valuation model incorporates changes in the price of the underlying copper derivative instrument, the time value of money, the underlying copper derivative instrument’s strike price and the remaining time to the underlying copper derivative instrument’s expiration date from the period end date. The guidance for the accounting and disclosure of derivatives and hedging transactions requires companies to recognize all of their derivative instruments as either assets or liabilities at fair value in the condensed consolidated statements of financial position. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies for hedge accounting treatment as defined under the applicable accounting guidance. For derivative instruments that are designated and qualify for hedge accounting treatment as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) in the condensed consolidated statements of comprehensive income (loss). This gain or loss is reclassified into earnings in the same line item of the condensed consolidated statements of operations associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. Foreign Currency During the three months ended June 30, 2022, we entered into U.S. dollar, euro, and Korean won forward contracts. We entered into these foreign currency forward contracts to mitigate certain global transactional exposures. These contracts do not qualify for hedge accounting treatment. As a result, any fair value adjustments required on these contracts are recorded in “Other income (expense), net” in our condensed consolidated statements of operations in the period in which the adjustment occurred. As of June 30, 2022, the notional values of the remaining foreign currency forward contracts were as follows: Notional Values of Foreign Currency Derivatives USD/CNH $ 8,640,104 EUR/USD € 14,213,070 KRW/USD ₩ 7,702,800,000 Commodity As of June 30, 2022, we had 12 outstanding contracts to hedge exposure related to the purchase of copper in our AES operating segment. These contracts are held with financial institutions and are intended to offset rising copper prices and do not qualify for hedge accounting treatment. As a result, any fair value adjustments required on these contracts are recorded in “Other income (expense), net” in our condensed consolidated statements of operations in the period in which the adjustment occurred. As of June 30, 2022, the volume of our copper contracts outstanding was as follows: Volume of Copper Derivatives July 2022 - September 2022 69 metric tons per month October 2022 - December 2022 69 metric tons per month January 2023 - March 2023 69 metric tons per month April 2023 - June 2023 69 metric tons per month Effects on Financial Statements The impacts from our derivative instruments on the statement of operations and statements of comprehensive income (loss) were as follows: Three Months Ended Six Months Ended (Dollars in thousands) Financial Statement Line Item June 30, 2022 June 30, 2021 June 30, 2022 June 30, 2021 Foreign Currency Contracts Contracts not designated as hedging instruments Other income (expense), net $ (236) $ (400) $ (918) $ (1,222) Copper Derivative Contracts Contracts not designated as hedging instruments Other income (expense), net $ (1,129) $ 1,313 $ (798) $ 3,860

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding and all dilutive potential common shares outstanding. The following table sets forth the computation of basic and diluted earnings per share: (Dollars and shares in thousands, except per share amounts) Three Months Ended Six Months Ended June 30, 2022 June 30, 2021 June 30, 2022 June 30, 2021 Numerator: Net income $ 17,883 $ 28,655 $ 34,483 $ 59,873 Denominator: Weighted-average shares outstanding - basic 18,813 18,729 18,797 18,721 Effect of dilutive shares 179 117 199 89 Weighted-average shares outstanding - diluted 18,992 18,846 18,996 18,810 Basic earnings per share $ 0.95 $ 1.53 $ 1.83 $ 3.20 Diluted earnings per share $ 0.94 $ 1.52 $ 1.82 $ 3.18 Dilutive shares are calculated using the treasury stock method and primarily include unvested restricted stock units. Anti-dilutive shares are excluded from the calculation of diluted shares and diluted earnings per share. For the three months ended June 30, 2022 and 2021, 226 shares and 1,769 shares were excluded, respectively.

Share-Based Payment Arrangement, Noncash Expense [Abstract]
Capital Stock and Equity Compensation	Capital Stock and Equity Compensation Equity Compensation Performance-Based Restricted Stock Units As of June 30, 2022, we had performance-based restricted stock units from 2021 and 2020 outstanding. These awards generally cliff vest at the end of a three-year measurement period. However, employees whose employment terminates during the measurement period due to death, disability, or, in certain cases, retirement may receive a pro-rata payout based on the number of days they were employed during the measurement period, except as noted below in Chief Executive Officer’s 2021 Equity Award Grants . Participants are eligible to be awarded shares ranging from 0% to 200% of the original award amount, based on certain defined performance measures. The outstanding awards have one measurement criterion: the three-year total shareholder return (TSR) on our capital stock as compared to that of a specified group of peer companies. The TSR measurement criterion of the awards is considered a market condition. As such, the fair value of this measurement criterion was determined on the grant date using a Monte Carlo simulation valuation model. We recognize compensation expense on all of these awards on a straight-line basis over the vesting period with no changes for final projected payout of the awards. We account for forfeitures as they occur. The following table sets forth the assumptions used in the Monte Carlo calculation for each material award granted in 2021: February 10, 2021 Expected volatility 51.0% Expected term (in years) 2.9 Risk-free interest rate 0.18% Expected volatility – In determining expected volatility, we have considered a number of factors, including historical volatility. Expected term – We use the vesting period of the award to determine the expected term assumption for the Monte Carlo simulation valuation model. Risk-free interest rate – We use an implied “spot rate” yield on U.S. Treasury Constant Maturity rates as of the grant date for our assumption of the risk-free interest rate. Expected dividend yield – We do not currently pay dividends on our capital stock; therefore, a dividend yield of 0% was used in the Monte Carlo simulation valuation model. A summary of activity of the outstanding performance-based restricted stock units for the six months ended June 30, 2022 is presented below: Performance-Based Awards outstanding as of December 31, 2021 114,554 Awards granted 26,819 Stock issued (60,053) Awards cancelled (1,415) Awards outstanding as of June 30, 2022 79,905 We recognized $1.1 million and $1.1 million of compensation expense for performance-based restricted stock units for the three months ended June 30, 2022 and 2021, respectively. We recognized $2.2 million and $3.2 million of compensation expense for performance-based restricted stock units for the six months ended June 30, 2022 and 2021, respectively. Time-Based Restricted Stock Units As of June 30, 2022, we had time-based restricted stock unit awards from 2022, 2021, 2020 and 2019 outstanding. The outstanding awards all ratably vest on the first, second and third anniversaries of the original grant date. However, employees whose employment terminates during the measurement period due to death, disability, or, in certain cases, retirement may receive a pro-rata payout based on the number of days they were employed subsequent to the last grant anniversary date, except as noted below in Chief Executive Officer’s 2021 Equity Award Grants . Each time-based restricted stock unit represents a right to receive one share of Rogers’ capital stock at the end of the vesting period. The fair value of the award is determined by the market value of the underlying stock price at the grant date. We recognize compensation expense on all of these awards on a straight-line basis over the vesting period. We account for forfeitures as they occur. A summary of activity of the outstanding time-based restricted stock units for the six months ended June 30, 2022 is presented below: Time-Based Awards outstanding as of December 31, 2021 96,989 Awards granted 62,510 Stock issued (46,222) Awards cancelled (2,021) Awards outstanding as of June 30, 2022 111,256 We recognized $2.5 million and $1.9 million of compensation expense for time-based restricted stock units for the three months ended June 30, 2022 and 2021, respectively. We recognized $4.6 million and $3.7 million of compensation expense for time-based restricted stock units for the six months ended June 30, 2022 and 2021, respectively. Chief Executive Officer’s 2021 Equity Award Grants The terms of the performance-based and time-based restricted stock unit awards granted to our Chief Executive Officer (CEO), Bruce Hoechner, in February 2021 were modified from the standard language provisions from prior year awards to allow for accelerated vesting of the full awards provided certain criteria are met. Accounting Standards Codification (ASC) Topic 718: Compensation—Stock Compensation requires companies that allow for accelerated vesting of employees’ unvested equity upon retirement to recognize the expense from the date of grant to the date the employee becomes eligible to retire – regardless of whether or not the employee actually retires when he or she is eligible to retire. As a result, the $4.0 million of expense in 2021 related to the awards granted on February 10, 2021 to our CEO, which provide for immediate vesting upon retirement, were expensed from the date of the grant, February 10, 2021, through his retirement eligibility date, November 9, 2021. Deferred Stock Units We grant deferred stock units to non-management directors. These awards are fully vested on the date of grant and the related shares are generally issued on the 13-month anniversary of the grant date unless the individual elects to defer the receipt of those shares. Each deferred stock unit results in the issuance of one share of Rogers’ capital stock. The grant of deferred stock units is typically done annually during the second quarter of each year. The fair value of the award is determined by the market value of the underlying stock price at the grant date. A summary of activity of the outstanding deferred stock units for the six months ended June 30, 2022 is presented below: Deferred Stock Units Awards outstanding as of December 31, 2021 9,500 Awards granted 4,800 Stock issued (7,450) Awards outstanding as of June 30, 2022 6,850 We recognized $1.3 million compensation expense for deferred stock units for the three and six months ended June 30, 2022 and $1.2 million of compensation expense for the three and six months ended June 30, 2021.

Debt Disclosure [Abstract]
Debt	Debt On October 16, 2020, we entered into the Fourth Amended and Restated Credit Agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (the Fourth Amended Credit Agreement). The Fourth Amended Credit Agreement amends and restates the Third Amended Credit Agreement, and provides for a revolving credit facility with up to a $450.0 million borrowing capacity, with sublimits for multicurrency borrowings, letters of credit and swing-line notes, in addition to a $175.0 million accordion feature. Borrowings may be used to finance working capital needs, for letters of credit and for general corporate purposes in the ordinary course of business, including the financing of permitted acquisitions (as defined in the Fourth Amended Credit Agreement). The Fourth Amended Credit Agreement extends the maturity, the date on which all amounts borrowed or outstanding under the Fourth Amended Credit Agreement are due, from February 17, 2022 to March 31, 2024. All obligations under the Fourth Amended Credit Agreement are guaranteed by each of our existing and future material domestic subsidiaries, as defined in the Fourth Amended Credit Agreement (the Guarantors). The obligations are also secured by a Fourth Amended and Restated Pledge and Security Agreement, dated as of October 16, 2020, entered into by us and the Guarantors which grants to the administrative agent, for the benefit of the lenders, a security interest, subject to certain exceptions, in substantially all of our and the Guarantors’ non-real estate assets. These assets include, but are not limited to, receivables, equipment, intellectual property, inventory, and stock in certain subsidiaries. On March 5, 2021, the U.K. Financial Conduct Authority (“FCA”) publicly announced that immediately after December 31, 2021, publication of most Euro, Swiss Franc, Japanese Yen and Pound Sterling LIBOR settings will permanently cease. On October 15, 2021, Rogers Corporation and JPMorgan Chase Bank, N.A. entered into an amendment (Amendment No. 1) to the Fourth Amended Credit Agreement to adopt a new benchmark interest rate to replace the discontinued LIBOR reference rates. Borrowings under the Fourth Amended Credit Agreement can be made as alternate base rate loans, euro-currency loans, or RFR loans. Alternate base rate loans bear interest at a base reference rate plus a spread of 62.5 to 100.0 basis points, depending on our leverage ratio. The base reference rate is the greatest of (a) the prime rate in effect on such day, (b) the NYFRB rate in effect on such day plus ½ of 1%, and (c) the adjusted LIBOR for a one month interest period in dollars on such day (or if such day is not a business day, the immediately preceding business day) plus 1%. Euro-currency loans bear interest based on adjusted LIBOR plus a spread of 162.5 to 200.0 basis points, depending on our leverage ratio. RFR loans bears interest based upon the Sterling Overnight Index Average (SONIA) plus 0.0326% plus a spread of 162.5 to 200.0 basis points. Based on our leverage ratio as of June 30, 2022, the spread was 162.5 basis points. In addition to interest payable on the principal amount of indebtedness outstanding, we incur an annual fee of 25 to 35 basis points (based upon our leverage ratio), paid quarterly, of the unused amount of the lenders’ commitments under the Fourth Amended Credit Agreement. The Fourth Amended Credit Agreement contains customary representations and warranties, covenants, mandatory prepayments and events of default under which our payment obligations may be accelerated. If an event of default occurs, the lenders may, among other things, terminate their commitments and declare all outstanding borrowings to be immediately due and payable together with accrued interest and fees. The financial covenants include requirements to maintain (1) a total net leverage ratio of no more than 3.25 to 1.00, subject to a one-time election to increase the maximum total net leverage ratio to 3.50 to 1.00 for one The Fourth Amended Credit Agreement generally permits us to pay cash dividends to our shareholders, provided that (i) no default or event of default has occurred and is continuing or would result from the dividend payment and (ii) our total net leverage ratio does not exceed 2.75 to 1.00. If our total net leverage ratio exceeds 2.75 to 1.00, we may nonetheless make up to $20.0 million in restricted payments, including cash dividends, during the fiscal year, provided that no default or event of default has occurred and is continuing or would result from the payments. Our total net leverage ratio did not exceed 2.75 to 1.00 as of June 30, 2022. We borrowed $70.0 million under the Fourth Amended Credit Agreement for the three and six months ended June 30, 2022. There were no borrowings for the three and six months ended June 30, 2021. We are not required to make any quarterly principal payments under the Fourth Amended Credit Agreement. We made no payments for the three and six months ended June 30, 2022, and $4.0 million and $25.0 million of discretionary principal payments on our revolving credit facility for the for the three and six months ended June 30, 2021, respectively. We had $260.0 million outstanding borrowings under our revolving credit facility as of June 30, 2022, and $190.0 million as of December 31, 2021. We had $1.3 million and $1.6 million of outstanding line of credit issuance costs as of June 30, 2022 and December 31, 2021, respectively, which will be amortized over the life of the Fourth Amended Credit Agreement.

Interest expense related to our finance lease obligations, which is included in the “Interest expense, net” line item of the condensed consolidated statements of operations, was immaterial for each of the three- and six-month periods ended June 30, 2022 and 2021. Payments made on the principal portion of our finance lease obligations were immaterial for each of the three- and six-month periods ended June 30, 2022 and 2021, excluding the $5.0 million net cash payment to exercise the Eschenbach, Germany manufacturing facility purchase option. We have operating leases primarily related to building space and vehicles. Renewal options are included in the lease term to the extent we are reasonably certain to exercise the option. The exercise of lease renewal options is at our sole discretion. We account for lease components separately from non-lease components.

Pension Benefits and Other Post

Pension Benefits and Other Postretirement Benefits	6 Months Ended

Retirement Benefits [Abstract]
Pension Benefit and Other Postretirement Benefits	Pension Benefits and Other Postretirement Benefits Pension and Other Postretirement Benefit Plans As of June 30, 2022, we had one qualified noncontributory defined benefit pension plan, the Rogers Corporation Employees’ Pension Plan (the Union Plan), which was frozen and ceased accruing benefits in 2013. Additionally, we sponsor other postretirement benefit plans, including multiple fully insured or self-funded medical plans and life insurance plans for certain retirees. The measurement date for all plans is December 31 st for each respective plan year. Pension Termination Surplus Funds On October 17, 2019, our Chief Executive Officer approved the termination of the Rogers Corporation Defined Benefit Pension Plan (following its merger with the Hourly Employees Pension Plan of Arlon LLC, Microwave Material and Silicone Technologies Divisions, Bear, Delaware (collectively, the Merged Plan)). We provided participants of the Merged Plan an option to elect either a lump sum distribution or an annuity. A group annuity contract was purchased with an insurance company for all participants who did not elect a lump sum distribution. The insurance company became responsible for administering and paying pension benefit payments effective January 1, 2020. Upon completion of the pension termination and settlement processes for the Merged Plan, we had a $9.7 million remaining pension surplus investment balance. In July 2020 and December 2021, we transferred $9.2 million of the pension surplus investment balance to a suspense account held within a trust for the Rogers Employee Savings and Investment Plan (RESIP), a 401(k) plan for domestic employees. In December 2021, we transferred the remaining pension investment balance not initially transferred, to the RESIP trust suspense account. The investment balance not transferred to the trust suspense account will be used to pay any final plan expenses, after which the remainder of these funds will be moved to the RESIP trust suspense account. The funds in the RESIP trust suspense account have been, and will continue to be, used to fund certain employer contributions. There was no remaining balance for the pension surplus investments as of June 30, 2022. Components of Net Periodic Benefit (Credit) Cost The components of net periodic benefit (credit) cost were as follows: Pension Benefits Other Postretirement Benefits Three Months Ended Six Months Ended Three Months Ended Six Months Ended June 30, June 30, June 30, June 30, (Dollars in thousands) 2022 2021 2022 2021 2022 2021 2022 2021 Service cost $ — $ — $ — $ — $ 10 $ 15 $ 20 $ 30 Interest cost 191 184 382 368 8 6 16 12 Expected return of plan assets (340) (390) (680) (780) — — — — Amortization of prior service credit — — — — — (24) — (48) Amortization of net loss 111 98 222 196 — — — — Net periodic benefit (credit) cost $ (38) $ (108) $ (76) $ (216) $ 18 $ (3) $ 36 $ (6) Employer Contributions There were no required or voluntary contributions made to the Union Plan or the Merged Plan for each of the three and six- months ended June 30, 2022 and 2021. Additionally, we are not required to make additional contributions to the Union Plan for the remainder of 2022. As there is no funding requirement for the other postretirement benefit plans, we funded these benefit payments as incurred, which were immaterial for each of the three and six- months ended June 30, 2022 and 2021, using cash from operations.

Commitments and Contingencies

Commitments and Contingencies	6 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We are currently engaged in the following material environmental and legal proceedings: Voluntary Corrective Action Program Our location in Rogers, Connecticut is part of the Connecticut Voluntary Corrective Action Program (VCAP). As part of this program, we partnered with the Connecticut Department of Energy and Environmental Protection (CT DEEP) to determine the corrective actions to be taken at the site related to contamination issues. We evaluated this matter and completed internal due diligence work related to the site in the fourth quarter of 2015. Remediation activities on the site are ongoing and are recorded as reductions to the accrual as they are incurred. We incurred $1.9 million of aggregate remediation costs through June 30, 2022, and the accrual for future remediation efforts is $0.8 million. Asbestos Overview We, like many other industrial companies, have been named as a defendant in a number of lawsuits filed in courts across the country by persons alleging personal injury from exposure to products containing asbestos. We have never mined, milled, manufactured or marketed asbestos; rather, we made and provided to industrial users a limited number of products that contained encapsulated asbestos, but we stopped manufacturing these products in the late 1980s. Most of the claims filed against us involve numerous defendants, sometimes as many as several hundred. The following table summarizes the change in number of asbestos claims outstanding for the six months ended June 30, 2022: Asbestos Claims Claims outstanding as of January 1 543 New claims filed 75 Pending claims concluded (1) (77) Claims outstanding as of June 30, 2022 541 (1) For the six months ended June 30, 2022, 67 claims were dismissed and 10 claims were settled. Settlements totaled approximately $1.5 million for the six months ended June 30, 2022. Impact on Financial Statements We recognize a liability for asbestos-related contingencies that are probable of occurrence and reasonably estimable. In connection with the recognition of liabilities for asbestos-related matters, we record asbestos-related insurance receivables that are deemed probable. The liability projection period covers all current and future indemnity and defense costs through 2064, which represents the expected end of our asbestos liability exposure with no further ongoing claims expected beyond that date. This conclusion was based on our history and experience with the claims data, the diminished volatility and consistency of observable claims data, the period of time that has elapsed since we stopped manufacturing products that contained encapsulated asbestos and an expected downward trend in claims due to the average age of our claimants, which is approaching the average life expectancy. To date, the indemnity and defense costs of our asbestos-related product liability litigation have been substantially covered by insurance. Although we have exhausted coverage under some of our insurance policies, we believe that we have applicable primary, excess and/or umbrella coverage for claims arising with respect to most of the years during which we manufactured and marketed asbestos-containing products. In addition, we have entered into a cost sharing agreement with most of our primary, excess and umbrella insurance carriers to facilitate the ongoing administration and payment of claims covered by the carriers. The cost sharing agreement may be terminated by any party, but will continue until a party elects to terminate it. As of the filing date for this report, the agreement has not been terminated, and no carrier had informed us it intended to terminate the agreement. We expect to continue to exhaust individual primary, excess and umbrella coverages over time, and there is no assurance that such exhaustion will not accelerate due to additional claims, damages and settlements or that coverage will be available as expected. We are responsible for uninsured indemnity and defense costs, and we incurred an immaterial amount of expenses for each of the three- and six-month periods ended June 30, 2022 and 2021, respectively, related to such costs. The amounts recorded for the asbestos-related liability and the related insurance receivables are based on facts known at the time and a number of assumptions. However, projecting future events, such as the number of new claims to be filed each year, the average cost of disposing of such claims, the length of time it takes to dispose of such claims, coverage issues among insurers and the continuing solvency of various insurance companies, as well as the numerous uncertainties surrounding asbestos litigation in the United States, could cause the actual liability and insurance recoveries for us to be higher or lower than those projected or recorded. Changes recorded in the estimated liability and estimated insurance recovery based on projections of asbestos litigation and corresponding insurance coverage, result in the recognition of expense or income. Our projected asbestos-related liabilities and insurance receivables were as follows: (Dollars in thousands) June 30, 2022 December 31, 2021 Asbestos-related liabilities $ 64,296 $ 68,332 Asbestos-related insurance receivables $ 58,877 $ 62,567 General In addition to the above issues, the nature and scope of our business brings us in regular contact with the general public and a variety of businesses and government agencies. Such activities inherently subject us to the possibility of litigation, including environmental and product liability matters that are defended and handled in the ordinary course of business. We have established accruals for matters for which management considers a loss to be probable and reasonably estimable. It is the opinion of management that facts known at the present time do not indicate that such litigation will have a material adverse impact on our results of operations, financial position or cash flows.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective income tax rate was 25.4% and 25.6% for the three months ended June 30, 2022 and 2021, respectively. The decrease from the second quarter of 2021 was primarily due to the beneficial impact of a decrease in current quarter accruals of reserves for uncertain tax positions. Our effective income tax rate was 22.2% and 25.4% for the six months ended June 30, 2022 and 2021, respectively. The decrease from the first half of 2021 was primarily due to the decrease in the current quarter accruals of reserves of unrecognized tax benefits, as well as the increase in the excess tax benefits associated with stock compensation windfalls. The total amount of unrecognized tax benefits as of June 30, 2022 was $7.3 million, of which $6.7 million would affect our effective tax rate if recognized. Additionally, the balance of unrecognized tax benefits as of June 30, 2022 also included $0.6 million of tax benefits that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes. We recognize interest and penalties related to unrecognized tax benefits through income tax expense. As of June 30, 2022, we had $1.2 million accrued for the payment of interest.
