NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 – Basis of Presentation

As used herein, the terms “Company,” “Rogers,” “we,” “us,” “our” and similar terms mean Rogers Corporation and its subsidiaries, unless the context indicates otherwise.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (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 transactions have been eliminated.

Interim results are not necessarily indicative of results for a full year. For further information regarding our accounting policies, refer to the audited consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2018.

Note 2 – 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.

From time to time we enter into various instruments that require fair value measurement, including foreign currency contracts, copper derivative contracts and interest rate swaps. Derivative instruments measured at fair value on a recurring basis, categorized by the level of inputs used in the valuation, include:

	Derivative Instruments at Fair Value as of March 31, 2019

Foreign currency contracts	$	—	$	(357	)	$	—	$	(357	)

Copper derivative contracts	$	—	$	583	$	—	$	583
Interest rate swap	$	—	$	461	$	—	$	461

For further discussion on our derivative contracts, refer to “Note 3 – Hedging Transactions and Derivative Financial Instruments.”

Note 3 – 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). During 2017, we entered into an interest rate swap to hedge interest rate risk. We do not use derivative financial 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.

8

• 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.

• Interest Rates- The fair value of interest rate swap instruments is derived by comparing the present value of the interest rate forward curve against the present value of the swap rate, relative to the notional amount of the swap. The net value represents the estimated amount we would receive or pay to terminate the agreements. Settlement amounts for an “in the money” swap would be adjusted down to compensate the counterparty for cost of funds, and the adjustment is directly related to the counterparties’ credit ratings.

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 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). 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. As of March 31, 2019 and 2018, only our interest rate swap qualified for hedge accounting treatment as a cash flow hedge, and the hedge was highly effective.

Foreign Currency

During the three months ended March 31, 2019, we entered into Chinese Renminbi 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 March 31, 2019, the notional values of the remaining foreign currency forward contracts were:

Notional Values of Foreign Currency Derivatives
USD/CNY	$	17,470,003
KRW/USD	₩	4,539,600,000

Commodity

As of March 31, 2019, we had 23 outstanding contracts to hedge exposure related to the purchase of copper in our Power Electronics Solutions (PES) and Advanced Connectivity Solutions (ACS) operating segments. 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 March 31, 2019, the volume of our copper contracts outstanding was as follows:

Volume of Copper Derivatives
April 2019 - June 2019	188 metric tons per month
July 2019 - September 2019	191 metric tons per month
October 2019 - December 2019	195 metric tons per month
January 2020 - March 2020	202 metric tons per month
April 2020 - June 2020	134 metric tons per month

Interest Rates

In March 2017, we entered into an interest rate swap to hedge the variable interest rate on $75 million of our $450 million revolving credit facility. This transaction has been designated as a cash flow hedge and qualifies for hedge accounting treatment. For additional information regarding our revolving credit facility, refer to “Note 10 – Debt.”

In the table above, gross carrying amounts and accumulated amortization may differ from prior periods due to foreign exchange rate fluctuations.

Amortization expense for the three months ended March 31, 2019 was approximately $4.4 million. Amortization expense for the three months ended March 31, 2018 was approximately $3.8 million. The estimated future amortization expense is $13.3 million for the remainder of 2019 and $14.6 million, $13.8 million, $13.3 million and $12.7 million for 2020, 2021, 2022 and 2023, respectively.

The weighted average amortization period as of March 31, 2019, by definite-lived other intangible asset class, is presented in the table below:

Note 8 – 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 for the periods indicated:

(In thousands, except per share amounts)	Three Months Ended
	March 31, 2019		March 31, 2018
Numerator:
Net income	$	28,399	$	26,136
Denominator:
Weighted-average shares outstanding - basic	18,557		18,288
Effect of dilutive shares	135		322
Weighted-average shares outstanding - diluted	18,692		18,610
Basic earnings per share	$	1.53	$	1.43
Diluted earnings per share	$	1.52	$	1.40

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 March 31, 2019, 23,081 shares were excluded. For the three months ended March 31, 2018, no shares were excluded.

Note 9 – Capital Stock and Equity Compensation

Equity Compensation

Performance-Based Restricted Stock Units

As of March 31, 2019, we had performance-based restricted stock units from 2019, 2018 and 2017 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. 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.

Below are the assumptions used in the Monte Carlo calculation on the respective grant dates for awards granted in 2019 and 2018:

	February 7, 2019	September 17, 2018	February 8, 2018
Expected volatility	36.7%	36.6%	34.8%
Expected term (in years)	2.9	3.0	3.0
Risk-free interest rate	2.43%	2.85%	2.28%

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.

13

The following table summarizes the change in number of performance-based restricted stock units outstanding for the three months ended March 31, 2019:

	Performance-Based Restricted Stock Units
Awards outstanding as of December 31, 2018	142,434
Awards granted	108,527
Stock issued	(131,650	)
Awards forfeited	(4,865	)
Awards outstanding as of March 31, 2019	114,446

We recognized $0.9 million and $1.0 million of compensation expense for performance-based restricted stock units during the three months ended March 31, 2019 and 2018, respectively.

Time-Based Restricted Stock Units

As of March 31, 2019, we had time-based restricted stock unit awards from 2019, 2018, 2017 and 2016 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. 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 three months ended March 31, 2019 is presented below:

	Time-Based Restricted Stock Units
Awards outstanding as of December 31, 2018	117,476
Awards granted	56,127
Stock issued	(63,948	)
Awards forfeited	(2,783	)
Awards outstanding as of March 31, 2019	106,872

We recognized $1.5 million of compensation expense related to time-based restricted stock units for each of the three months ended March 31, 2019 and 2018.

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.

The following table summarizes the change in number of deferred stock units outstanding during the three months ended March 31, 2019:

	Deferred Stock Units
Awards outstanding as of December 31, 2018	8,400
Awards granted	—
Stock issued	—
Awards outstanding as of March 31, 2019	8,400

We recognized no compensation expense related to deferred stock units during the three months ended March 31, 2019 and 2018.

14

Stock Options

Stock options have been granted under various equity compensation plans. The maximum contractual term for all options is normally 10 years. All outstanding options are fully vested and exercisable. We have not granted any stock options since the first quarter of 2012.

During the three months ended March 31, 2019, the total intrinsic value of options exercised (i.e., the difference between the market price at time of exercise and the price paid by the individual to exercise the options) was $0.9 million, and the total amount of cash received from the exercise of these options was $0.3 million.

A summary of the activity under our stock option plans for the three months ended March 31, 2019 is presented below:

	Options Outstanding		Weighted- Average Exercise Price Per Share		Weighted-Average Remaining Contractual Life in Years	Aggregate Intrinsic Value
Options outstanding, vested and exercisable as of December 31, 2018	10,950		$	31.99	2.0	$	734,469
Options exercised	(8,250	)	$	34.55
Options expired	(300	)	$	23.86
Options outstanding, vested and exercisable as of March 31, 2019	2,400		$	24.20	0.9	$	323,232

Employee Stock Purchase Plan

We have an employee stock purchase plan (ESPP) that allows eligible employees to purchase, through payroll deductions, shares of our capital stock at a discount to fair market value. The ESPP has twosix-month offering periods each year, the first beginning in January and ending in June and the second beginning in July and ending in December. The ESPP contains a look-back feature that allows the employee to acquire shares of our capital stock at a 15% discount from the underlying market price at the beginning or end of the applicable period, whichever is lower. We recognize compensation expense on this plan ratably over the offering period based on the fair value of the anticipated number of shares that will be issued at the end of each offering period. Compensation expense is adjusted at the end of each offering period for the actual number of shares issued. Fair value is determined based on two factors: (i) the 15% discount on the underlying stock’s market value on the first day of the applicable offering period, and (ii) the fair value of the look-back feature determined by using the Black-Scholes model. We recognized an immaterial amount of equity compensation expense associated with the ESPP for each of the three-month periods ended March 31, 2019 and 2018.

Note 10 – Debt

In 2017, we entered into a secured five year credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (the Third Amended Credit Agreement), which increased the principal amount of our revolving credit facility to up to $450.0 million borrowing capacity, with sublimits for multicurrency borrowings, letters of credit and swing-line notes, and provided an additional $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 Third Amended Credit Agreement).

In 2018, we borrowed $82.5 million under our revolving credit facility to fund the acquisition of Griswold and an additional $20.0 million to fund the Merged Plan as part of the proposed plan termination process.

Borrowings under the Third Amended Credit Agreement can be made as alternate base rate loans or euro-currency loans. Alternate base rate loans bear interest that includes a base reference rate plus a spread of 37.5 to 75.0 basis points, depending on our leverage ratio. The base reference rate is the greater of the prime rate; federal funds effective rate (or the overnight bank funding rate, if greater) plus 50 basis points. Euro-currency loans bear interest based on adjusted LIBOR plus a spread of 137.5 to 175.0 basis points, depending on our leverage ratio. Based on our leverage ratio as of March 31, 2019, the spread was 150.0 basis points.

We incurred interest expense on our outstanding debt of $2.1 million, and $0.9 million during the three months ended March 31, 2019 and 2018, respectively.

In addition to interest payable on the principal amount of indebtedness outstanding from time to time under the Third Amended Credit Agreement, we are required to pay a quarterly fee of 20 to 30 basis points (based upon our leverage ratio) of the unused amount of the lenders’ commitments under the Third Amended Credit Agreement. We incurred immaterial unused commitment fees in each of the three-month periods ended March 31, 2019 and 2018.

The Third Amended Credit Agreement contains customary representations, 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

15

with accrued interest and fees. The financial covenants include requirements to maintain (1) a leverage ratio of no more than 3.25 to 1.00, subject to an election to increase the maximum leverage ratio to 3.50 to 1.00 for one fiscal year in connection with a permitted acquisition, and (2) an interest coverage ratio of no less than 3.00 to 1.00.

All obligations under the Third Amended Credit Agreement are guaranteed by each of our existing and future material domestic subsidiaries, as defined in the Third Amended Credit Agreement (the Guarantors). The obligations are also secured by a Third Amended and Restated Pledge and Security Agreement, dated as of February 17, 2017, 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 the non-real estate assets of the Guarantors. These assets include, but are not limited to, receivables, equipment, intellectual property, inventory, and stock in certain subsidiaries.

All revolving loans are due on the maturity date, February 17, 2022. We are not required to make any quarterly principal payments under the Third Amended Credit Agreement, and as of March 31, 2019 we had $223.5 million in outstanding borrowings under our revolving credit facility. However, we made a discretionary principal payment totaling $5.0 million on our revolving credit facility during the three months ended March 31, 2019.

As of March 31, 2019, we had $1.6 million of outstanding line of credit issuance costs that will be amortized over the life of the Third Amended Credit Agreement, which will terminate in February 2022. We recognized an immaterial amount of amortization expense for each of the three month periods ended March 31, 2019 and 2018, related to these deferred costs.

In March 2017, we entered into an interest rate swap to hedge the variable interest rate on $75.0 million of our $450.0 million revolving credit facility. For further information regarding the interest rate swap, refer to “Note 3 – Hedging Transactions and Derivative Financial Instruments.”

Restriction on Payment of Dividends

Our Third 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 leverage ratio does not exceed 2.75 to 1.00. If our 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 leverage ratio did not exceed 2.75 to 1.00 as of March 31, 2019.

Note 11 - Leases

We have a finance lease obligation related to our manufacturing facility in Eschenbach, Germany. Under the terms of the lease agreement, we have an option to purchase the property upon the expiration of the lease in 2021 at a price which is the greater of (i) the then-current market value or (ii) the residual book value of the land including the buildings and installations thereon. Our finance lease obligation related to this facility was $4.8 million and $5.0 million as of March 31, 2019 and December 31, 2018, respectively. The finance lease right-of-use asset balance for this facility was $6.5 million and $6.7 million as of March 31, 2019 and December 31, 2018, respectively. All other finance lease obligations and finance lease right-of-use assets were cumulatively immaterial as of March 31, 2019 and December 31, 2018. Accumulated amortization related to our finance lease right-of-use assets was $3.6 million and $3.5 million as of March 31, 2019 and December 31, 2018, respectively.

Amortization expense related to our finance lease right-of-use assets, which is included in the “Cost of sales” line item of the condensed consolidated statements of operations, was immaterial for each of the three-month periods ended March 31, 2019 and 2018. 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-month periods ended March 31, 2019 and 2018. Payments made on the principal portion of our finance lease obligations were immaterial for each of the three-month periods ended March 31, 2019 and 2018.

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. The incremental borrowing rate represents our ability to borrow on a collateralized basis over a similar lease term.

The following table includes our expenses and payments for operating leases for the three months ended March 31, 2019:

(Dollars in thousands)	Three Months Ended
	March 31, 2019

	Finance Leases	Operating Leases
Weighted Average Remaining Lease Term	2.3 years	3.0 years
Weighted Average Discount Rate	2.55%	6.16%

Transition

We adopted Accounting Standards Codification (ASC) 842, Leases, in the first quarter of 2019 using the optional transition method, which applies the new lease requirements through a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without restatement of comparative periods. The adoption primarily affected our condensed consolidated statements of financial position through the recognition of $6.2 million of operating lease right-of-use assets and $6.2 million of operating lease obligations, as well as an immaterial impact to retained earnings, as of January 1, 2019. We recognized an additional $0.7 million of operating lease right-of-use assets and $0.7 million operating lease obligations during the three months ended March 31, 2019. The total operating lease right-of use assets and operating lease obligations recognized was $6.9 million and $6.9 million, respectively. The guidance was applied to all leases that were not completed at the date of implementation.

Practical Expedients

We have elected to recognize lease payments in the condensed consolidated statements of operations on a straight-line basis over the term of the lease for short-term leases. We also elected the package of practical expedients that allows us to carry forward the historical lease classification and accounting for indirect costs for any existing leases.

Note 12 – Pension Benefits and Other Postretirement Benefit Plans

As of March 31, 2019, we had two qualified noncontributory defined benefit pension plans: 1) the Union Plan and 2) the Rogers Corporation Defined Benefit Pension Plan for (i) all other U.S. employees hired before December 31, 2007 who are salaried employees or non-union hourly employees and (ii) employees of the acquired Arlon business (the Merged Plan).

The Company also maintains the Rogers Corporation Amended and Restated Pension Restoration Plan effective as of January 1, 2004 and the Rogers Corporation Amended and Restated Pension Restoration Plan effective as of January 1, 2005 (collectively, the Nonqualified Plans). The Nonqualified Plans serve to restore certain retirement benefits that might otherwise be lost due to limitations imposed by federal law on qualified pension plans, as well as to provide supplemental retirement benefits, for certain senior executives of the Company. In addition, we sponsor 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.

We are required, as an employer, to: (a) recognize in our consolidated statements of financial position an asset for a plan’s overfunded status or a liability for a plan’s underfunded status; (b) measure a plan’s assets and our obligations that determine our funded status as of the end of the year; and (c) recognize changes in the funded status of a defined benefit postretirement plan in the year in which the changes occur and report these changes in accumulated other comprehensive loss. In addition, actuarial gains and losses that are not immediately recognized as net periodic pension cost are recognized as a component of accumulated other comprehensive loss and amortized into net periodic pension cost in future periods.

Pension Plan Proposed Termination

The Company currently intends to terminate the Merged Plan and has received a determination letter from the Internal Revenue Service (IRS). The termination of the Merged Plan remains subject to final approval by management. The Company plans to provide participants an option to elect either a lump sum distribution or an annuity. One or more group annuity contracts with one or more insurance companies will be purchased to settle our obligations for those participants who do not receive a lump sum. The Merged Plan is fully-funded on a GAAP basis, however, in order to terminate the plan in accordance with IRS and Pension Benefit Guaranty Corporation requirements, the Company will be required to contribute additional assets, if necessary, to settle all of the Merged Plan’s obligations. The amount necessary to do so is not yet known. In addition, the Company expects to record a pension settlement charge at plan termination. This settlement charge will include the immediate recognition into expense of the unrecognized losses within accumulated other comprehensive loss on the statement of financial position as of the plan termination date. The Company does not have a current estimate of this future charge, however, the pre-tax accumulated other comprehensive loss related to the Merged Plan was approximately $47 million as of December 31, 2018. The settlement charge for the accumulated other comprehensive loss would be a non-cash charge. We currently estimate that if the plan termination is approved by management, it will be completed during the fourth quarter of 2019, when lump sum distributions are expected to occur and one or more annuity contracts are expected to be purchased. At this time, there are no plans to terminate the Union Plan.

Components of Net Periodic (Benefit) Cost

The components of net periodic (benefit) cost for the periods indicated were:

Amortization of net loss	454			456			—			—
Net periodic cost (benefit)	$	46		$	(33	)	$	(220	)	$	(365	)

Employer Contributions

There were no required contributions to our qualified defined benefit pension plans for the three months ended March 31, 2019 and 2018, and we are not required to make additional contributions to these plans for the remainder of 2019. No voluntary contributions were made to our qualified defined benefit pension plans for the three months ended March 31, 2019 and 2018.

As there is no funding requirement for the Nonqualified Plans or the Retiree Health and Life Insurance benefit plans, we fund the amount of benefit payments made during the year, which were immaterial for the three months ended March 31, 2019 and 2018.

Note 13 – Commitments and Contingencies

We are currently engaged in the following 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 an immaterial amount of aggregate remediation costs through March 31, 2019, and the accrual for future remediation efforts is $1.7 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 during the three months ended March 31, 2019:

	Asbestos Claims
Claims outstanding as of December 31, 2018	745
New claims filed	82
Pending claims concluded*	(38	)
Claims outstanding as of March 31, 2019	789

*For the three months ended March 31, 2019, 34 claims were dismissed and 4 claims were settled. Settlements totaled approximately $0.5 million for the three months ended March 31, 2019.

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 claims through 2058, 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 defense and settlement costs of our asbestos-related product liability litigation have been substantially covered by insurance. We have identified continuous coverage for primary, excess and umbrella insurance from the 1950s through the mid-1980s, except for a period in the early 1960s, with respect to which we have entered into an agreement for primary, but not excess or umbrella, coverage. 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 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. During 2018, we received notices that primary coverage for a period of eight years and excess coverage for a period of three years had been exhausted. In the three months ended March 31, 2019, we incurred an immaterial amount of indemnity and defense costs, primarily related to the period referenced above. We expect 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.

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

19

the United States, could cause the actual liability and insurance recoveries for us to be higher or lower than those projected or recorded.

For the three months ended March 31, 2019 and December 31, 2018, our projected asbestos-related claims and insurance receivables were as follows:

(Dollars in millions)	March 31, 2019		December 31, 2018
Asbestos-related claims	$	70.2	$	70.3
Asbestos-related insurance receivables	$	63.8	$	63.8

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.

Note 14 – Income Taxes

Our effective income tax rate was 14.2% and 15.4% for the three months ended March 31, 2019 and 2018, respectively. The decrease from the first quarter of 2018 was primarily due to the beneficial impact of the international tax provisions from U.S. tax reform as a result of administrative guidance issued during 2018, excess tax deductions on equity compensation and a lower tax impact on unremitted foreign earnings and profits, partially offset by a one-time impact from R&D credits and a decrease in current quarter reversals of uncertain tax positions.

The total amount of unrecognized tax benefits as of March 31, 2019 was $9.2 million, of which $8.9 million would affect our effective tax rate if recognized. It is reasonably possible that approximately $1.4 million of our unrecognized tax benefits as of March 31, 2019 will reverse within the next 12 months.

We recognize interest and penalties related to unrecognized tax benefits through income tax expense. As of March 31, 2019, we had $0.6 million accrued for the payment of interest.

We are subject to taxation in the U.S. and various state and foreign jurisdictions. With few exceptions, we are no longer subject to examinations by tax authorities for years prior to 2014.

Note 15 – Segment Information

Our reporting structure is comprised of the following strategic operating segments: ACS, EMS and PES. The remaining operations, which represent our non-core businesses, are reported in the Other operating segment. We believe this structure aligns our external reporting presentation with how we currently manage and view our business internally.

On January 1, 2018, we adopted Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers. For additional information regarding the impacts of this accounting guidance, refer to “Note 16 – Revenue from Contracts with Customers.” We sell products to fabricators and distributors who then sell directly into various end markets. End markets within our ACS operating segment include wireless infrastructure, aerospace and defense, automotive, connected devices, wired infrastructure and consumer electronics. End markets within our EMS operating segment include portable electronics, mass transit, automotive, consumer and general industrial. End markets within our PES operating segment include e-mobility, industrial, renewable energy, mass transit, and micro channel coolers. End markets in our Other operating segment include automotive and industrial.

Note 16 – Revenue from Contracts with Customers

Contract Balances

The Company has contract assets primarily related to unbilled revenue for revenue recognized related to products that are deemed to have no alternative use whereby we have the right to payment. Revenue is recognized in advance of billing to the customer in these circumstances as billing is typically performed at the time of shipment to the customer. The unbilled revenue is included in the contract assets on the condensed consolidated statements of financial position.

The Company did not have any contract liabilities as of March 31, 2019 or December 31, 2018.

The following table presents contract assets by operating segment as of March 31, 2019 and December 31, 2018:

(Dollars in thousands)	March 31, 2019		December 31, 2018
Advanced Connectivity Solutions	$	—	$	—

Power Electronics Solutions	24,636		19,738
Other	1,915		2,047
Total contract assets	$	27,315	$	22,728

No impairment losses were recognized during the three months ended March 31, 2019 and 2018 on any receivables or contract assets arising from our contracts with customers.

Note 17 – Restructuring and Impairment Charges

In 2018, we made the decision to consolidate our Santa Fe Springs, California operations into the Company’s facilities in Carol Stream, Illinois and Bear, Delaware. We recorded $0.8 million of expense for the three months ended March 31, 2019 related to the facility consolidation. The fair value of the total severance benefits paid in connection with the facility consolidation was $0.5 million. The total severance costs were expensed ratably over the required service period for the affected employees. All severance expenses were recorded as of December 31, 2018, and the final severance payments were made in the first quarter of 2019.

The following table presents severance activity related to the facility consolidation for the three months ended March 31, 2019:

Note 19 – Recent Accounting Standards

Recently Issued Standards

In August 2018, the Financial Accounting Standards Board (FASB) issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, which modifies the disclosure requirements for employers that sponsor defined benefit plans or other postretirement plans. This ASU is effective for our fiscal year ending December 31, 2020, with early adoption permitted. ASU 2018-14 is required to be applied on a retrospective basis to all periods presented. The Company is currently evaluating the potential impact of adopting this guidance on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements by removing the requirement to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and the policy for timing of such transfers. This ASU expands the disclosure requirements for Level 3 fair value measurements, primarily focused on changes in unrealized gains and losses included in other comprehensive income (loss). This ASU is effective for our fiscal year ending December 31, 2020 and for the interim periods within that year. Early adoption is permitted. ASU 2018-13 is generally required to be applied retrospectively to all periods presented upon their effective date with the exception of certain amendments, that should be applied prospectively to the most recent interim or annual period presented in the year of adoption. The Company is currently evaluating the potential impact of adopting this guidance on our consolidated financial statements.

Recently Adopted Standards Reflected in Our 2019 Financial Statements

In October 2018, the FASB issued ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes, which permits the use of the OIS rate based on the SOFR as a U.S. benchmark interest rate for hedge accounting purposes. The amendments in this update were effective for the Company on January 1, 2019 and the Company will apply the amendments in this update to qualifying new or redesignated hedging relationships.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract,which aligns the requirements for capitalizing costs incurred in the implementation of a hosting arrangement that is a service contract with the requirements for capitalizing costs incurred to develop or obtain internal use software. The Company adopted this ASU on January 1, 2019 on a prospective basis and it did not have a material impact on our condensed consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows for reclassification of stranded tax effects resulting from U.S. Tax Reform from accumulated other comprehensive loss to retained earnings but it does not require this reclassification. The Company adopted this ASU on January 1, 2019 and elected to not reclassify the stranded tax effects resulting from U.S. Tax Reform. As a result of that election, the adoption of ASU 2018-02 did not have an impact on the Company’s consolidated financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to classify leases as either finance or operating leases and record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. An accounting policy election may be made to account for leases with a term of 12 months or less similar to existing guidance for operating leases today. ASU 2016-02 supersedes the existing guidance on accounting for leases. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which allows for an optional transition method for the adoption of Topic 842. The two permitted transition methods are now the modified retrospective approach, which applies the new lease requirements at the beginning of the earliest period presented, and the optional transition method, which applies the new lease requirements through a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company adopted this standard on January 1, 2019 using the optional transition method. The Company elected to use the practical expedients that allow us to carry forward the historical lease classification. For additional information regarding the impact of the adoption of this standard, refer to “Note 11 - Leases.”

Note 20 – Share Repurchases

In 2015, we initiated a share repurchase program (the Program) of up to $100.0 million of the Company’s capital stock. We initiated the Program to mitigate potentially dilutive effects of stock options and shares of restricted stock granted by the Company, in addition to enhancing shareholder value. The Program has no expiration date, and may be suspended or discontinued at any time without notice. No share repurchases were made during the three months ended March 31, 2019. During the three months ended March 31, 2018, we repurchased 23,138 shares of our capital stock for $3.0 million. As of March 31, 2019, $49.0 million remained of our $100.0 million share repurchase program.

Results of Operations

In the first quarter of 2019 as compared to the first quarter of 2018, our net sales increased11.7% to $239.8 million, gross margin decreased approximately 10 basis points to 35.6%, and operating margin decreased approximately 80 basis points to 13.7%.

The following table sets forth, for the periods indicated, selected operations data expressed as a percentage of net sales:

	Three Months Ended

Net Sales
	Three Months Ended
(Dollars in thousands)	March 31, 2019		March 31, 2018		Percent Change
Net sales	$	239,798	$	214,611	11.7%

Net sales increased by 11.7% in the first quarter of 2019 compared to the first quarter of 2018. Our ACS, EMS and PES operating segments had net sales increases of 9.6%, 18.8% and 3.6%, respectively. The increase in net sales was driven in part by net sales of $7.8 million, or 3.6%, related to our acquisition of Griswold LLC (Griswold) in July 2018. Net sales were favorably impacted by higher net sales in both 5G and 4G wireless infrastructure, as well as aerospace and defense and portable electronics applications in the ACS operating segment, higher net sales in portable electronics, mass transit and automotive applications in the EMS operating segment and higher net sales in EV/HEV and mass transit applications in the PES operating segment. Net sales were unfavorably impacted by $6.1 million, or 2.9%, due to the depreciation in value of the Euro and Renminbi relative to the U.S. dollar.

Gross margin as a percentage of net sales decreased approximately 10 basis points to 35.6% in the first quarter of 2019 compared to 35.7% in the first quarter of 2018. Gross margin in the first quarter of 2019 was negatively impacted by productivity challenges, higher fixed overhead expenses and increased freight costs in our PES operating segment, partially offset by higher net sales across all operating segments, as well as the resolution of certain process issues that had negatively impacted gross margin in the first quarter of 2018, favorable product mix and increased asset utilization in our ACS operating segment.

Percentage of net sales	18.0		%	18.9		%

Selling, general and administrative (SG&A) expenses increased6.5% in the first quarter of 2019 from the first quarter of 2018, primarily due to a $0.7 million increase charge resulting from a change in foreign jurisdiction tax regulation on equity awards, a $0.6 million in higher incentive compensation expense, a $0.6 million increase in other intangible assets amortization, most of which is related to our acquisition of Griswold, and $0.3 million in SG&A expenses related to Griswold.

Research and Development Expenses
	Three Months Ended
(Dollars in thousands)	March 31, 2019			March 31, 2018			Percent Change
Research and development expenses	$	7,609		$	8,134		(6.5)%
Percentage of net sales	3.2		%	3.8		%

R&D expenses decreased6.5% in the first quarter of 2019 from the first quarter of 2018. The decrease is due to the timing of new product initiatives.

Restructuring and Impairment Charges and Other Operating Expenses (Income), Net
	Three Months Ended
(Dollars in thousands)	March 31, 2019		March 31, 2018			Percent Change
Restructuring and impairment charges	$	822	$	422		94.8%
Other operating (income) expense, net	911		(3,591		)	(125.4)%

We incurred restructuring charges associated with the relocation of our global headquarters from Rogers, Connecticut to Chandler, Arizona and the consolidation of our Santa Fe Springs, California operations with the Company’s facilities in Carol Stream, Illinois and Bear, Delaware. We recognized $0.8 million of restructuring charges associated with the facility consolidation in the first quarter of 2019, and $0.4 million of restructuring charges related to the headquarters relocation in the first quarter of 2018. We estimate that approximately $0.4 million of additional spend for capital expenditures related to the facility consolidation will occur in the remainder of 2019.

With respect to other operating (income) expense, net, in the first quarter of 2019, we recognized lease income of approximately $0.5 million and related depreciation on leased assets of approximately $1.2 million in connection with the transitional leaseback of a portion of the facility and certain machinery and equipment acquired from Isola USA Corp. (Isola) in August 2018. In the first quarter of 2018, we recognized a $3.6 million gain from the settlement of antitrust litigation in other operating income.

Equity Income in Unconsolidated Joint Ventures
	Three Months Ended
(Dollars in thousands)	March 31, 2019		March 31, 2018		Percent Change
Equity income in unconsolidated joint ventures	$	837	$	1,007	(16.9)%

As of March 31, 2019, we had two unconsolidated joint ventures, each 50% owned: Rogers INOAC Corporation (RIC) and Rogers INOAC Suzhou Corporation (RIS). Equity income in those unconsolidated joint ventures decreased16.9% in the first quarter of 2019 from the first quarter of 2018. The decrease was due to lower net sales for RIC in portable electronics applications and unfavorable foreign currency impacts on RIS.

(Dollars in thousands)	March 31, 2019		March 31, 2018		Percent Change
Other income (expense), net	$	1,404	$	66	2,027.3%

Other income (expense), net increased to $1.4 million in the first quarter of 2019 from approximately $0.1 million in the first quarter of 2018. The increase was due to favorable impacts from our copper derivative contracts.

Interest Expense, Net
	Three Months Ended
(Dollars in thousands)	March 31, 2019			March 31, 2018			Percent Change
Interest expense, net	$	(1,938	)	$	(1,210	)	60.2%

Interest expense, net, increased by 60.2% in the first quarter of 2019 from the first quarter of 2018 due to higher average outstanding balances on our revolving credit facility in the first quarter of 2019 compared to the first quarter of 2018. This is a result of borrowings under our revolving credit facility during the third quarter of 2018 to fund the acquisition of Griswold and our voluntary pension contribution in connection with the proposed plan termination process.

Effective tax rate	14.2		%	15.4		%

Our effective income tax rate was 14.2% and 15.4% for the three months ended March 31, 2019 and 2018, respectively. The decrease from the first quarter of 2018 was primarily due to the beneficial impact of the international tax provisions from U.S. tax reform as a result of administrative guidance issued during 2018, excess tax deductions on equity compensation and a lower tax impact on unremitted foreign earnings and profits, partially offset by a one-time impact from R&D credits and a decrease in current quarter reversals of uncertain tax positions.

Operating Segment Net Sales and Operating Income

(Dollars in thousands)	March 31, 2019		March 31, 2018
Net sales	$	80,470	$	73,455

Our ACS operating segment designs, develops, manufactures and sells circuit materials and solutions enabling high-performance and high-reliability connectivity for applications in wireless infrastructure (e.g., power amplifiers, antennas, small cells and distributed antenna systems), automotive (e.g., active safety, advanced driver assistance systems, telematics and thermal management), aerospace and defense, connected devices (e.g., mobile internet devices and Internet of Things), wired infrastructure (e.g., computing and IP infrastructure) and consumer electronics. In August 2018, we purchased assets from Isola to expand capacity in the ACS operating segment in an effort to prepare for potential demand from our 5G customers.

Q1 2019 versus Q1 2018

ACS net sales increased by 9.6% in the first quarter of 2019 compared to the first quarter of 2018. The increase in net sales over the first quarter of 2018 was primarily driven by higher net sales in both 5G and 4G wireless infrastructure, as well as aerospace and defense and portable electronics applications. Net sales were unfavorably impacted by $1.8 million, or 2.4%, due to the depreciation in value of the Euro and Renminbi relative to the U.S. dollar.

Operating income increased by 65.3% in the first quarter of 2019 from the first quarter of 2018. As a percentage of net sales, operating income in the first quarter of 2019 was 16.2%, an approximately 540 basis point increase as compared to the 10.8% reported in the first quarter of 2018. The increase in operating income is primarily due to higher net sales, favorable product mix, increased asset utilization and the resolution of certain process issues in our ACS operating segment that had negatively impacted gross margin in the first quarter of 2018.

Our EMS operating segment designs, develops, manufactures and sells engineered material solutions for a wide variety of applications and end markets. These applications and end markets include polyurethane and silicone materials used in critical cushioning, sealing and vibration management applications for portable electronics (e.g., smart phones), automotive, aerospace, rail, footwear and printing end markets; customized silicones used in flex heater and semiconductor thermal applications; polytetrafluoroethylene and ultra-high molecular weight polyethylene materials used in wire and cable, pressure-sensitive tapes and automotive applications.

Q1 2019 versus Q1 2018

EMS net sales increased by 18.8% in the first quarter of 2019 compared to the first quarter of 2018. The increase in net sales over the first quarter of 2018 was primarily driven by net sales related to our acquisition of Griswold of $7.8 million, or 9.9%, along with higher net sales in portable electronics, mass transit and automotive applications. Net sales were unfavorably impacted by $1.5 million, or 1.9%, due to the depreciation in value of the Euro and Renminbi relative to the U.S. dollar.

Operating income decreased by 5.1% in the first quarter of 2019 from the first quarter of 2018. As a percentage of net sales, first quarter of 2019 operating income was 14.5%, an approximately 360 basis point decrease as compared to the 18.1% reported in the first quarter of 2018. The decrease in operating income is primarily due to the non-recurring $3.6 million gain from the settlement of antitrust litigation in the first quarter of 2018, as well as $0.8 million of facility consolidation costs in the first quarter of 2019, largely offset by higher net sales.

Our PES operating segment designs, develops, manufactures and sells ceramic substrate materials for power module applications (e.g., variable frequency drives, vehicle electrification and renewable energy), laminated busbars for power inverter and high power interconnect applications (e.g., mass transit, hybrid-electric and electric vehicles, renewable energy and variable frequency drives) and micro-channel coolers (e.g., laser cutting equipment). We sell our ceramic substrate materials and micro-channel coolers under the curamik^® trade name, and our busbars under the ROLINX^® trade name.

Q1 2019 versus Q1 2018

PES net sales increased by 3.6% in the first quarter of 2019 from the first quarter of 2018. The increase in net sales over the first quarter of 2018 was primarily driven by higher net sales in EV/HEV and mass transit applications. Net sales were impacted by unfavorable currency fluctuations of $2.7 million, or 4.7%, due to the depreciation in value of the Euro and Renminbi relative to the U.S. dollar.

Operating income decreased by 39.2% in the first quarter of 2019 from the first quarter of 2018. As a percentage of net sales, first quarter of 2019 operating income was 7.1%, an approximately 510 basis point decrease as compared to the 12.2% reported in the first quarter of 2018. The decrease in operating income is primarily due to productivity challenges, higher fixed overhead expenses and increased freight costs, partially offset by higher net sales.

communications and automotive markets. Trade names for our elastomer components include: NITROPHYL^® floats for level sensing in fuel tanks, motors, and storage tanks and ENDUR^® elastomer rollers.

Q1 2019 versus Q1 2018

Net sales in this segment increased by 26.0% in the first quarter of 2019 from the first quarter of 2018. The increase in net sales over the first quarter of 2018 was primarily driven by a last-time buy in the Durel business.

Operating income increased3.9% in the first quarter of 2019 compared to the first quarter of 2018. This increase in operating income was primarily driven by higher net sales, partially offset by higher fixed overhead expenses. As a percentage of net sales, first quarter of 2019 operating income was 30.2%, an approximately 640 basis point decrease as compared to the 36.6% reported in the first quarter of 2018.

Liquidity, Capital Resources and Financial Position

We believe that our existing sources of liquidity and cash flows that we expect to generate from our operations, together with our available credit facilities, will be sufficient to fund our operations, currently planned capital expenditures, research and development efforts and our debt service commitments, for at least the next 12 months. We regularly review and evaluate the adequacy of our cash flows, borrowing facilities and banking relationships in an effort to ensure that we have the appropriate access to cash to fund both our near-term operating needs and our long-term strategic initiatives.

The following table illustrates the location of our cash and cash equivalents by our three major geographic areas:

(Dollars in thousands)	March 31, 2019		December 31, 2018
United States	$	35,105	$	41,833
Europe	29,380		31,244
Asia	97,589		94,661
Total cash and cash equivalents	$	162,074	$	167,738

Approximately $127.0 million of our cash and cash equivalents were held by non-U.S. subsidiaries as of March 31, 2019. The Company did not make any changes in the first quarter of 2019 to its position on the permanent reinvestment of its earnings from foreign operations. With the exception of certain of our Chinese subsidiaries, we continue to assert that historical foreign earnings are indefinitely reinvested.

Changes in key financial position accounts and other significant changes in our statements of financial position from December 31, 2018 to March 31, 2019 were as follows:

• Accounts receivable, less allowance for doubtful accounts increased11.1% to $160.7 millionas of March 31, 2019, from $144.6 million as of December 31, 2018. The increase from year-end was primarily due to higher net sales at the end of the first quarter of 2019 compared to at the end of the 2018.

• Contract assets increased20.2% to $27.3 millionas of March 31, 2019, from $22.7 million as of December 31, 2018, as a result of an increase in no-alternative-use inventory, mainly attributable to the increase in demand in our PES operating segment.

• Inventories increased0.5% to $133.2 million as of March 31, 2019, from $132.6 million as of December 31, 2018, primarily driven by increased raw material purchases in anticipation of higher expected demand in our ACS operating segment.

• Borrowings under revolving credit facilitydecreased2.2% to $223.5 million as of March 31, 2019, from $228.5 million as of December 31, 2018, as a result of a $5.0 million principal payment made in the first quarter of 2019.

As of March 31, 2019, cash and cash equivalents were $162.1 million as compared to $167.7 million as of December 31, 2018, a decrease of $5.7 million, or 3.4%. This decrease was primarily due to $12.6 million in capital expenditures, a $5.0 million principal payment made on our outstanding borrowings under our revolving credit facility and $7.1 million in tax payments related to net share settlement of equity awards, largely offset by cash flows generated by operations.

Revolving Credit Facility

In 2017, we entered into a secured five year credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (the Third Amended Credit Agreement), which amended and restated the Second Amended Credit Agreement. The Third Amended Credit Agreement refinanced the Second Amended Credit Agreement, eliminated the term loan under the Second Amended Credit Agreement, increased the principal amount of our revolving credit facility to up to $450.0 million of borrowing capacity, with sublimits for multicurrency borrowings, letters of credit and swing-line notes, and provided an additional $175.0 million accordion feature.

All revolving loans under the Third Amended Credit Agreement are due on the maturity date, February 17, 2022. We are not required to make any quarterly principal payments under the Third Amended Credit Agreement. As of March 31, 2019, we had $223.5 million in outstanding borrowings under our revolving credit facility.

Restrictions on Payment of Dividends

Our Third 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 leverage ratio does not exceed 2.75 to 1.00. If our 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 leverage ratio did not exceed 2.75 to 1.00 as of March 31, 2019.

Contingencies

During the first quarter of 2019, we did not become aware of any material developments related to environmental matters disclosed in our Annual Report, our asbestos litigation or other material contingencies previously disclosed or incur any material costs or capital expenditures related to such matters. Refer to “Note 13 – Commitments and Contingencies” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q for further discussion of these contingencies.

Off-Balance Sheet Arrangements

As of March 31, 2019, we did not have any off-balance sheet arrangements that have or are, in the opinion of management, reasonably likely to have a current or future material effect on our results of operations or financial position.

Critical Accounting Policies

Leases

In February 2016, the FASB issued ASU 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). In our adoption of ASU 2016-02, we applied the practical expedients to recognize lease payments in the condensed consolidated statements of operations on a straight-line basis over the term of the lease for short-term leases. Additionally, we elected the package of practical expedients that allows us to carry forward the historical lease classification and accounting for indirect costs for any existing leases. Refer to “Note 11 - Leases” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q.

Recent Accounting Pronouncements

Refer to “Note 19 – Recent Accounting Standards” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q for discussion of recent accounting pronouncements including expected dates of adoption.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes in our exposure to market risk during the first quarter of 2019. For discussion of our exposure to market risk, refer to “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” contained in our Annual Report.

Item 4. Controls and Procedures

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

The Company, with the participation of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d- 15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of March 31, 2019. The Company’s disclosure controls and procedures are designed (i) to ensure that information required to be disclosed by it in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) to ensure that information required to be disclosed in the reports the Company files or submits under the Exchange Act is accumulated and communicated to its management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Based on their evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2019.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

There were no changes in the Company’s internal control over financial reporting during its most recently completed fiscal quarter that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting, as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 2 – 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.

From time to time we enter into various instruments that require fair value measurement, including foreign currency contracts, copper derivative contracts and interest rate swaps. Derivative instruments measured at fair value on a recurring basis, categorized by the level of inputs used in the valuation, include:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Hedging Transactions and Derivative Financial Instruments

Note 3 – 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). During 2017, we entered into an interest rate swap to hedge interest rate risk. We do not use derivative financial 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.

• Interest Rates- The fair value of interest rate swap instruments is derived by comparing the present value of the interest rate forward curve against the present value of the swap rate, relative to the notional amount of the swap. The net value represents the estimated amount we would receive or pay to terminate the agreements. Settlement amounts for an “in the money” swap would be adjusted down to compensate the counterparty for cost of funds, and the adjustment is directly related to the counterparties’ credit ratings.

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 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). 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. As of March 31, 2019 and 2018, only our interest rate swap qualified for hedge accounting treatment as a cash flow hedge, and the hedge was highly effective.

Foreign Currency

During the three months ended March 31, 2019, we entered into Chinese Renminbi 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 March 31, 2019, the notional values of the remaining foreign currency forward contracts were:

Notional Values of Foreign Currency Derivatives
USD/CNY	$	17,470,003
KRW/USD	₩	4,539,600,000

Commodity

As of March 31, 2019, we had 23 outstanding contracts to hedge exposure related to the purchase of copper in our Power Electronics Solutions (PES) and Advanced Connectivity Solutions (ACS) operating segments. 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 March 31, 2019, the volume of our copper contracts outstanding was as follows:

Volume of Copper Derivatives
April 2019 - June 2019	188 metric tons per month
July 2019 - September 2019	191 metric tons per month
October 2019 - December 2019	195 metric tons per month
January 2020 - March 2020	202 metric tons per month
April 2020 - June 2020	134 metric tons per month

Interest Rates

In March 2017, we entered into an interest rate swap to hedge the variable interest rate on $75 million of our $450 million revolving credit facility. This transaction has been designated as a cash flow hedge and qualifies for hedge accounting treatment. For additional information regarding our revolving credit facility, refer to “Note 10 – Debt.”

Equity Compensation

Performance-Based Restricted Stock Units

As of March 31, 2019, we had performance-based restricted stock units from 2019, 2018 and 2017 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. 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.

Below are the assumptions used in the Monte Carlo calculation on the respective grant dates for awards granted in 2019 and 2018:

	February 7, 2019	September 17, 2018	February 8, 2018
Expected volatility	36.7%	36.6%	34.8%
Expected term (in years)	2.9	3.0	3.0
Risk-free interest rate	2.43%	2.85%	2.28%

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.

The following table summarizes the change in number of performance-based restricted stock units outstanding for the three months ended March 31, 2019:

	Performance-Based Restricted Stock Units
Awards outstanding as of December 31, 2018	142,434
Awards granted	108,527

We recognized $0.9 million and $1.0 million of compensation expense for performance-based restricted stock units during the three months ended March 31, 2019 and 2018, respectively.

Time-Based Restricted Stock Units

As of March 31, 2019, we had time-based restricted stock unit awards from 2019, 2018, 2017 and 2016 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. 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 three months ended March 31, 2019 is presented below:

	Time-Based Restricted Stock Units
Awards outstanding as of December 31, 2018	117,476
Awards granted	56,127
Stock issued	(63,948	)
Awards forfeited	(2,783	)
Awards outstanding as of March 31, 2019	106,872

We recognized $1.5 million of compensation expense related to time-based restricted stock units for each of the three months ended March 31, 2019 and 2018.

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.

The following table summarizes the change in number of deferred stock units outstanding during the three months ended March 31, 2019:

	Deferred Stock Units
Awards outstanding as of December 31, 2018	8,400
Awards granted	—
Stock issued	—
Awards outstanding as of March 31, 2019	8,400

We recognized no compensation expense related to deferred stock units during the three months ended March 31, 2019 and 2018.

Stock Options

Stock options have been granted under various equity compensation plans. The maximum contractual term for all options is normally 10 years. All outstanding options are fully vested and exercisable. We have not granted any stock options since the first quarter of 2012.

During the three months ended March 31, 2019, the total intrinsic value of options exercised (i.e., the difference between the market price at time of exercise and the price paid by the individual to exercise the options) was $0.9 million, and the total amount of cash received from the exercise of these options was $0.3 million.

A summary of the activity under our stock option plans for the three months ended March 31, 2019 is presented below:

	Options Outstanding		Weighted- Average Exercise Price Per Share		Weighted-Average Remaining Contractual Life in Years	Aggregate Intrinsic Value
Options outstanding, vested and exercisable as of December 31, 2018	10,950		$	31.99	2.0	$	734,469
Options exercised	(8,250	)	$	34.55
Options expired	(300	)	$	23.86
Options outstanding, vested and exercisable as of March 31, 2019	2,400		$	24.20	0.9	$	323,232

Employee Stock Purchase Plan

We have an employee stock purchase plan (ESPP) that allows eligible employees to purchase, through payroll deductions, shares of our capital stock at a discount to fair market value. The ESPP has twosix-month offering periods each year, the first beginning in January and ending in June and the second beginning in July and ending in December. The ESPP contains a look-back feature that allows the employee to acquire shares of our capital stock at a 15% discount from the underlying market price at the beginning or end of the applicable period, whichever is lower. We recognize compensation expense on this plan ratably over the offering period based on the fair value of the anticipated number of shares that will be issued at the end of each offering period. Compensation expense is adjusted at the end of each offering period for the actual number of shares issued. Fair value is determined based on two factors: (i) the 15% discount on the underlying stock’s market value on the first day of the applicable offering period, and (ii) the fair value of the look-back feature determined by using the Black-Scholes model. We recognized an immaterial amount of equity compensation expense associated with the ESPP for each of the three-month periods ended March 31, 2019 and 2018.

Debt Disclosure [Abstract]

Debt

Note 10 – Debt

In 2017, we entered into a secured five year credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (the Third Amended Credit Agreement), which increased the principal amount of our revolving credit facility to up to $450.0 million borrowing capacity, with sublimits for multicurrency borrowings, letters of credit and swing-line notes, and provided an additional $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 Third Amended Credit Agreement).

In 2018, we borrowed $82.5 million under our revolving credit facility to fund the acquisition of Griswold and an additional $20.0 million to fund the Merged Plan as part of the proposed plan termination process.

Borrowings under the Third Amended Credit Agreement can be made as alternate base rate loans or euro-currency loans. Alternate base rate loans bear interest that includes a base reference rate plus a spread of 37.5 to 75.0 basis points, depending on our leverage ratio. The base reference rate is the greater of the prime rate; federal funds effective rate (or the overnight bank funding rate, if greater) plus 50 basis points. Euro-currency loans bear interest based on adjusted LIBOR plus a spread of 137.5 to 175.0 basis points, depending on our leverage ratio. Based on our leverage ratio as of March 31, 2019, the spread was 150.0 basis points.

We incurred interest expense on our outstanding debt of $2.1 million, and $0.9 million during the three months ended March 31, 2019 and 2018, respectively.

In addition to interest payable on the principal amount of indebtedness outstanding from time to time under the Third Amended Credit Agreement, we are required to pay a quarterly fee of 20 to 30 basis points (based upon our leverage ratio) of the unused amount of the lenders’ commitments under the Third Amended Credit Agreement. We incurred immaterial unused commitment fees in each of the three-month periods ended March 31, 2019 and 2018.

The Third Amended Credit Agreement contains customary representations, 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 leverage ratio of no more than 3.25 to 1.00, subject to an election to increase the maximum leverage ratio to 3.50 to 1.00 for one fiscal year in connection with a permitted acquisition, and (2) an interest coverage ratio of no less than 3.00 to 1.00.

All obligations under the Third Amended Credit Agreement are guaranteed by each of our existing and future material domestic subsidiaries, as defined in the Third Amended Credit Agreement (the Guarantors). The obligations are also secured by a Third Amended and Restated Pledge and Security Agreement, dated as of February 17, 2017, 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 the non-real estate assets of the Guarantors. These assets include, but are not limited to, receivables, equipment, intellectual property, inventory, and stock in certain subsidiaries.

All revolving loans are due on the maturity date, February 17, 2022. We are not required to make any quarterly principal payments under the Third Amended Credit Agreement, and as of March 31, 2019 we had $223.5 million in outstanding borrowings under our revolving credit facility. However, we made a discretionary principal payment totaling $5.0 million on our revolving credit facility during the three months ended March 31, 2019.

As of March 31, 2019, we had $1.6 million of outstanding line of credit issuance costs that will be amortized over the life of the Third Amended Credit Agreement, which will terminate in February 2022. We recognized an immaterial amount of amortization expense for each of the three month periods ended March 31, 2019 and 2018, related to these deferred costs.

In March 2017, we entered into an interest rate swap to hedge the variable interest rate on $75.0 million of our $450.0 million revolving credit facility. For further information regarding the interest rate swap, refer to “Note 3 – Hedging Transactions and Derivative Financial Instruments.”

Restriction on Payment of Dividends

Our Third 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 leverage ratio does not exceed 2.75 to 1.00. If our 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 leverage ratio did not exceed 2.75 to 1.00 as of March 31, 2019.

Note 11 - Leases

We have a finance lease obligation related to our manufacturing facility in Eschenbach, Germany. Under the terms of the lease agreement, we have an option to purchase the property upon the expiration of the lease in 2021 at a price which is the greater of (i) the then-current market value or (ii) the residual book value of the land including the buildings and installations thereon. Our finance lease obligation related to this facility was $4.8 million and $5.0 million as of March 31, 2019 and December 31, 2018, respectively. The finance lease right-of-use asset balance for this facility was $6.5 million and $6.7 million as of March 31, 2019 and December 31, 2018, respectively. All other finance lease obligations and finance lease right-of-use assets were cumulatively immaterial as of March 31, 2019 and December 31, 2018. Accumulated amortization related to our finance lease right-of-use assets was $3.6 million and $3.5 million as of March 31, 2019 and December 31, 2018, respectively.

Amortization expense related to our finance lease right-of-use assets, which is included in the “Cost of sales” line item of the condensed consolidated statements of operations, was immaterial for each of the three-month periods ended March 31, 2019 and 2018. 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-month periods ended March 31, 2019 and 2018. Payments made on the principal portion of our finance lease obligations were immaterial for each of the three-month periods ended March 31, 2019 and 2018.

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. The incremental borrowing rate represents our ability to borrow on a collateralized basis over a similar lease term.

Transition

We adopted Accounting Standards Codification (ASC) 842, Leases, in the first quarter of 2019 using the optional transition method, which applies the new lease requirements through a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without restatement of comparative periods. The adoption primarily affected our condensed consolidated statements of financial position through the recognition of $6.2 million of operating lease right-of-use assets and $6.2 million of operating lease obligations, as well as an immaterial impact to retained earnings, as of January 1, 2019. We recognized an additional $0.7 million of operating lease right-of-use assets and $0.7 million operating lease obligations during the three months ended March 31, 2019. The total operating lease right-of use assets and operating lease obligations recognized was $6.9 million and $6.9 million, respectively. The guidance was applied to all leases that were not completed at the date of implementation.

Practical Expedients

We have elected to recognize lease payments in the condensed consolidated statements of operations on a straight-line basis over the term of the lease for short-term leases. We also elected the package of practical expedients that allows us to carry forward the historical lease classification and accounting for indirect costs for any existing leases.

Pension Benefits and Other Postretirement Benefit Plans

Mar. 31, 2019

Defined Benefit Plan [Abstract]

Pension Benefit and Other Postretirement Benefit Plans

Note 12 – Pension Benefits and Other Postretirement Benefit Plans

As of March 31, 2019, we had two qualified noncontributory defined benefit pension plans: 1) the Union Plan and 2) the Rogers Corporation Defined Benefit Pension Plan for (i) all other U.S. employees hired before December 31, 2007 who are salaried employees or non-union hourly employees and (ii) employees of the acquired Arlon business (the Merged Plan).

The Company also maintains the Rogers Corporation Amended and Restated Pension Restoration Plan effective as of January 1, 2004 and the Rogers Corporation Amended and Restated Pension Restoration Plan effective as of January 1, 2005 (collectively, the Nonqualified Plans). The Nonqualified Plans serve to restore certain retirement benefits that might otherwise be lost due to limitations imposed by federal law on qualified pension plans, as well as to provide supplemental retirement benefits, for certain senior executives of the Company. In addition, we sponsor 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.

We are required, as an employer, to: (a) recognize in our consolidated statements of financial position an asset for a plan’s overfunded status or a liability for a plan’s underfunded status; (b) measure a plan’s assets and our obligations that determine our funded status as of the end of the year; and (c) recognize changes in the funded status of a defined benefit postretirement plan in the year in which the changes occur and report these changes in accumulated other comprehensive loss. In addition, actuarial gains and losses that are not immediately recognized as net periodic pension cost are recognized as a component of accumulated other comprehensive loss and amortized into net periodic pension cost in future periods.

Pension Plan Proposed Termination

The Company currently intends to terminate the Merged Plan and has received a determination letter from the Internal Revenue Service (IRS). The termination of the Merged Plan remains subject to final approval by management. The Company plans to provide participants an option to elect either a lump sum distribution or an annuity. One or more group annuity contracts with one or more insurance companies will be purchased to settle our obligations for those participants who do not receive a lump sum. The Merged Plan is fully-funded on a GAAP basis, however, in order to terminate the plan in accordance with IRS and Pension Benefit Guaranty Corporation requirements, the Company will be required to contribute additional assets, if necessary, to settle all of the Merged Plan’s obligations. The amount necessary to do so is not yet known. In addition, the Company expects to record a pension settlement charge at plan termination. This settlement charge will include the immediate recognition into expense of the unrecognized losses within accumulated other comprehensive loss on the statement of financial position as of the plan termination date. The Company does not have a current estimate of this future charge, however, the pre-tax accumulated other comprehensive loss related to the Merged Plan was approximately $47 million as of December 31, 2018. The settlement charge for the accumulated other comprehensive loss would be a non-cash charge. We currently estimate that if the plan termination is approved by management, it will be completed during the fourth quarter of 2019, when lump sum distributions are expected to occur and one or more annuity contracts are expected to be purchased. At this time, there are no plans to terminate the Union Plan.

Components of Net Periodic (Benefit) Cost

The components of net periodic (benefit) cost for the periods indicated were:

	Pension Benefits						Retirement Health and Life Insurance Benefits
(Dollars in thousands)	Three Months Ended						Three Months Ended

Amortization of net loss	454			456			—			—
Net periodic cost (benefit)	$	46		$	(33	)	$	(220	)	$	(365	)

Employer Contributions

There were no required contributions to our qualified defined benefit pension plans for the three months ended March 31, 2019 and 2018, and we are not required to make additional contributions to these plans for the remainder of 2019. No voluntary contributions were made to our qualified defined benefit pension plans for the three months ended March 31, 2019 and 2018.

As there is no funding requirement for the Nonqualified Plans or the Retiree Health and Life Insurance benefit plans, we fund the amount of benefit payments made during the year, which were immaterial for the three months ended March 31, 2019 and 2018.

Commitments and Contingencies

Note 13 – Commitments and Contingencies

We are currently engaged in the following 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 an immaterial amount of aggregate remediation costs through March 31, 2019, and the accrual for future remediation efforts is $1.7 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 during the three months ended March 31, 2019:

	Asbestos Claims
Claims outstanding as of December 31, 2018	745
New claims filed	82
Pending claims concluded*	(38	)
Claims outstanding as of March 31, 2019	789

*For the three months ended March 31, 2019, 34 claims were dismissed and 4 claims were settled. Settlements totaled approximately $0.5 million for the three months ended March 31, 2019.

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 claims through 2058, 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 defense and settlement costs of our asbestos-related product liability litigation have been substantially covered by insurance. We have identified continuous coverage for primary, excess and umbrella insurance from the 1950s through the mid-1980s, except for a period in the early 1960s, with respect to which we have entered into an agreement for primary, but not excess or umbrella, coverage. 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 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. During 2018, we received notices that primary coverage for a period of eight years and excess coverage for a period of three years had been exhausted. In the three months ended March 31, 2019, we incurred an immaterial amount of indemnity and defense costs, primarily related to the period referenced above. We expect 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.

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.

For the three months ended March 31, 2019 and December 31, 2018, our projected asbestos-related claims and insurance receivables were as follows:

(Dollars in millions)	March 31, 2019		December 31, 2018
Asbestos-related claims	$	70.2	$	70.3
Asbestos-related insurance receivables	$	63.8	$	63.8

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

Note 14 – Income Taxes

Our effective income tax rate was 14.2% and 15.4% for the three months ended March 31, 2019 and 2018, respectively. The decrease from the first quarter of 2018 was primarily due to the beneficial impact of the international tax provisions from U.S. tax reform as a result of administrative guidance issued during 2018, excess tax deductions on equity compensation and a lower tax impact on unremitted foreign earnings and profits, partially offset by a one-time impact from R&D credits and a decrease in current quarter reversals of uncertain tax positions.

The total amount of unrecognized tax benefits as of March 31, 2019 was $9.2 million, of which $8.9 million would affect our effective tax rate if recognized. It is reasonably possible that approximately $1.4 million of our unrecognized tax benefits as of March 31, 2019 will reverse within the next 12 months.

We recognize interest and penalties related to unrecognized tax benefits through income tax expense. As of March 31, 2019, we had $0.6 million accrued for the payment of interest.

We are subject to taxation in the U.S. and various state and foreign jurisdictions. With few exceptions, we are no longer subject to examinations by tax authorities for years prior to 2014.

Note 19 – Recent Accounting Standards

Recently Issued Standards

In August 2018, the Financial Accounting Standards Board (FASB) issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, which modifies the disclosure requirements for employers that sponsor defined benefit plans or other postretirement plans. This ASU is effective for our fiscal year ending December 31, 2020, with early adoption permitted. ASU 2018-14 is required to be applied on a retrospective basis to all periods presented. The Company is currently evaluating the potential impact of adopting this guidance on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements by removing the requirement to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and the policy for timing of such transfers. This ASU expands the disclosure requirements for Level 3 fair value measurements, primarily focused on changes in unrealized gains and losses included in other comprehensive income (loss). This ASU is effective for our fiscal year ending December 31, 2020 and for the interim periods within that year. Early adoption is permitted. ASU 2018-13 is generally required to be applied retrospectively to all periods presented upon their effective date with the exception of certain amendments, that should be applied prospectively to the most recent interim or annual period presented in the year of adoption. The Company is currently evaluating the potential impact of adopting this guidance on our consolidated financial statements.

Recently Adopted Standards Reflected in Our 2019 Financial Statements

In October 2018, the FASB issued ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes, which permits the use of the OIS rate based on the SOFR as a U.S. benchmark interest rate for hedge accounting purposes. The amendments in this update were effective for the Company on January 1, 2019 and the Company will apply the amendments in this update to qualifying new or redesignated hedging relationships.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract,which aligns the requirements for capitalizing costs incurred in the implementation of a hosting arrangement that is a service contract with the requirements for capitalizing costs incurred to develop or obtain internal use software. The Company adopted this ASU on January 1, 2019 on a prospective basis and it did not have a material impact on our condensed consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows for reclassification of stranded tax effects resulting from U.S. Tax Reform from accumulated other comprehensive loss to retained earnings but it does not require this reclassification. The Company adopted this ASU on January 1, 2019 and elected to not reclassify the stranded tax effects resulting from U.S. Tax Reform. As a result of that election, the adoption of ASU 2018-02 did not have an impact on the Company’s consolidated financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to classify leases as either finance or operating leases and record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. An accounting policy election may be made to account for leases with a term of 12 months or less similar to existing guidance for operating leases today. ASU 2016-02 supersedes the existing guidance on accounting for leases. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which allows for an optional transition method for the adoption of Topic 842. The two permitted transition methods are now the modified retrospective approach, which applies the new lease requirements at the beginning of the earliest period presented, and the optional transition method, which applies the new lease requirements through a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company adopted this standard on January 1, 2019 using the optional transition method. The Company elected to use the practical expedients that allow us to carry forward the historical lease classification. For additional information regarding the impact of the adoption of this standard, refer to “Note 11 - Leases.”
