ROGERS CORPORATION

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.

Certain reclassifications have been made to prior period balances in the statements of financial position in order to conform to the current period presentation. In addition, the Company reclassified $0.9 million of Gain on sale of long-lived asset to Other operating income (expense), net on the condensed consolidated statements of operations for the three months ended March 31, 2017.

On January 1, 2018, the Company adopted ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost. Upon adoption, the Company reclassified $0.4 million in net periodic pension benefits from Selling, general and administrative expenses to Other income (expense), net for the three months ended March 31, 2017. See Note 21, “Recent Accounting Standards” for further information.

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 fiscal year ended December 31, 2017.

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, 2018
(Dollars in thousands)	Level 1		Level 2			Level 3		Total
Foreign currency contracts	$	—	$	(329	)	$	—	$	(329	)

Copper derivative contracts	$	—	$	2,016		$	—	$	2,016
Interest rate swap	$	—	$	41		$	—	$	41

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 the first quarter of 2017, we entered into an interest rate swap to hedge interest rate risk. We do not use derivative financial

7

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. 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 the constant 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. Overall, fair value is a function of five primary variables: price of the underlying instrument, time to expiration, strike price, interest rate, and volatility.

• 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, 2018, only our interest rate swap qualified for hedge accounting treatment as a cash flow hedge. For the three months endedMarch 31, 2018 and 2017, the hedge was highly effective.

Foreign Currency

During the quarter ended March 31, 2018, we entered into Korean Won, Japanese Yen, Euro, Hungarian Forint and Chinese Renminbi 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.

As of March 31, 2018 the notional values of these foreign currency forward contracts were:

Notional Values of Foreign Currency Derivatives
KRW/USD	₩	2,477,560,000
JPY/EUR	¥	310,000,000
EUR/USD	€	8,081,989
EUR/HUF	€	608,174
USD/CNY	$	10,637,837

Commodity

We currently have twenty-four outstanding contracts to hedge exposure related to the purchase of copper in our Power Electronics Solutions (PES) and Advanced Connectivity Solutions (ACS) operations. These contracts are held with financial institutions and minimize the risk associated with a potential rise in copper prices. These contracts provide some coverage over the forecasted 2018 and 2019 monthly copper exposure 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 occurs. The notional values of our copper contracts outstanding as of March 31, 2018 were:

Volume of Copper Derivatives
April 2018 - June 2018	153 metric tons per month
July 2018 - September 2018	153 metric tons per month
October 2018 - December 2018	153 metric tons per month
January 2019 - March 2019	162 metric tons per month
April 2019 - June 2019	56 metric tons per month

Interest Rates

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. This transaction has been designated as a cash flow hedge and qualifies for hedge accounting treatment. See Note 12, “Debt” for further discussion regarding the credit facility.

Note 5 – Acquisitions

Diversified Silicone Products

On January 6, 2017, we acquired the principal operating assets of Diversified Silicone Products, Inc. (DSP), pursuant to the terms of the Asset Purchase Agreement by and among the Company, DSP and the principal shareholders of DSP (the Purchase Agreement). Pursuant to the terms of the Purchase Agreement, we acquired certain assets and assumed certain liabilities of DSP for a total purchase price of approximately $60.2 million.

We used borrowings of $30.0 million under our credit facility in addition to cash on hand to fund the acquisition.

DSP is a custom silicone product development and manufacturing business and expands the portfolio of our Elastomeric Material Solutions (EMS) operating segment in cellular sponge and specialty extruded silicone profile technologies, while strengthening existing expertise in precision-calendered silicone and silicone formulating and compounding.

The results of DSP have been included in our condensed consolidated financial statements only for the periods subsequent to the completion of our acquisition on January 6, 2017.

Note 7 – Earnings Per Share

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,
	2018		2017
Numerator:
Net income	$	26,136	$	27,032
Denominator:
Weighted-average shares outstanding - basic	18,288		18,056
Effect of dilutive shares	322		317
Weighted-average shares outstanding - diluted	18,610		18,373
Basic earnings per share	$	1.43	$	1.50
Diluted earnings per share	$	1.40	$	1.47

Certain potential options to purchase shares may be excluded from the calculation of diluted weighted-average shares outstanding where their exercise price is greater than the average market price of our capital stock during the relevant reporting period. For the quarters ended March 31, 2018 and March 31, 2017, no shares were excluded.

Note 8 – Stock-Based Compensation

Equity Compensation Awards

Performance-Based Restricted Stock Units

As of March 31, 2018, we had performance-based restricted stock awards from 2016, 2017 and 2018 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. Compensation expense is recognized using the straight-line method over the measurement period, unless the employee has an accelerated vesting schedule.

The 2016, 2017 and 2018 awards have one measurement criteria: the three year total shareholder return (TSR) on the performance of our capital stock as compared to that of a specified group of peer companies. The TSR measurement criteria of the awards is considered a market condition. As such, the fair value of this measurement criteria was determined on the date of grant using a Monte Carlo simulation valuation model, with related compensation expense fixed on the grant date and expensed on a straight-line basis over the life of the awards that ultimately vest and with no changes for the final projected payout of the awards.

Below were the assumptions used in the Monte Carlo calculation:

	March 31, 2018	March 31, 2017
Expected volatility	34.8%	33.6%
Expected term (in years)	3.0	3.0
Risk-free interest rate	2.28%	1.38%

Expected volatility – In determining expected volatility, we have considered a number of factors, including historical volatility.

Expected term – We use the measurement 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.

Forfeiture Rate – We account for forfeitures as they occur.

11

The following table summarizes the change in number of performance-based restricted stock awards outstanding for the three months ended March 31, 2018:

	Performance-Based Restricted Stock Awards
Awards outstanding at December 31, 2017	169,202
Awards granted	72,160
Stock issued	(81,230	)
Awards forfeited	(1,735	)
Awards outstanding at March 31, 2018	158,397

During the three months ended March 31, 2018, we recognized compensation expense for performance-based restricted stock awards of approximately $1.0 million. During the three months ended March 31, 2017, we recognized compensation income for performance-based restricted stock awards of approximately $0.1 million. 

Time-Based Restricted Stock Units

As of March 31, 2018, we had time-based restricted stock grants from 2014, 2015, 2016, 2017 and 2018 outstanding. The 2015, 2016, 2017 and 2018 grants all ratably vest on the first, second and third anniversaries of the original grant date. We recognize compensation expense on all of these awards on a straight-line basis over the vesting period. The Company issued 2,200 time-based restricted stock units to key employees in 2014 that cliff vest on December 17, 2018. Each restricted stock unit represents a right to receive one share of the Rogers’ capital stock at the end of the vesting period.

The fair value of the award is determined based on the market value of the underlying stock price at the grant date. We account for forfeitures as they occur.

The following table summarizes the change in number of time-based restricted stock awards outstanding for the three months ended March 31, 2018:

	Time-Based Restricted Stock Awards
Awards outstanding at December 31, 2017	173,331
Awards granted	41,100
Stock issued	(76,996	)
Awards forfeited	(1,990	)
Awards outstanding at March 31, 2018	135,445

During the three months ended March 31, 2018 we recognized compensation expense for time-based restricted stock awards of approximately $1.5 million. During the three months ended March 31, 2017 we recognized compensation expense for time-based restricted stock awards of approximately $1.0 million.

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 based on 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, 2018:

	Deferred Stock Units
Awards outstanding at December 31, 2017	9,250
Awards granted	—
Stock issued	—
Awards outstanding at March 31, 2018	9,250

During the each of the three-month periods ended March 31, 2018 and 2017, we recognized no compensation expense associated with the deferred stock units.

12

Stock Options

Stock options have been granted under various equity compensation plans, and they generally became exercisable in one-third increments on the second, third and fourth anniversaries of the grant dates. The maximum contractual term for all options was normally ten years. We used the Black-Scholes option-pricing model to calculate the grant-date fair value of an option. We have not granted any stock options since the first quarter of 2012.

A summary of the activity under our stock option plans during the three months ended March 31, 2018 and changes during the three months then ended, is presented below:

	Options Outstanding		Weighted- Average Exercise Price Per Share		Weighted-Average Remaining Contractual Life in Years	Aggregate Intrinsic Value
Options outstanding at December 31, 2017	33,283		$	36.40	2.2	$	4,177,655
Options exercised	(11,383	)	$	41.56
Options forfeited	—		$	—
Options outstanding at March 31, 2018	21,900		$	33.72	2.1	$	1,879,485
Options exercisable at March 31, 2018	21,900		$	33.72	2.1	$	1,879,485
Options vested at March 31, 2018	21,900		$	33.72	2.1	$	1,879,485

During the three months ended March 31, 2018, 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 $1.5 million, and the total amount of cash received from the exercise of these options was $0.5 million.

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 approximately $0.1 million of compensation expense associated with the plan in each of the three month periods ended March 31, 2018 and 2017.

Note 9 – Pension Benefits and Other Postretirement Benefit Plans

We have two qualified noncontributory defined benefit pension plans: 1) the Rogers Corporation Employee’s Pension Plan for unionized hourly employees (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 Rogers 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 for each respective plan year.

Employer Contributions

There were no required contributions to our qualified defined benefit pension plans in the first quarter of 2018 and we are not required to make additional contributions to these plans in 2018. We paid $0.1 million of required contributions in the first quarter of 2017.

In the first quarter of 2018 and 2017, we did not make any voluntary contributions to our defined benefit pension plans.

As there is no funding requirement for the non-qualified unfunded noncontributory defined benefit pension plan or the retiree health and life insurance benefit plans, benefit payments made during the year are funded directly by the Company.

Pension Plan Proposed Termination

The Company currently intends to terminate the Rogers Plan and has requested a determination letter from the Internal Revenue Service (IRS). The termination of the Rogers Plan remains subject to final approval by both management and the IRS. The Company plans to provide for lump sum distributions or annuity payments in connection with the termination of the Rogers Plan and we expect the settlement process to be completed in late 2018 or early 2019. The Company lacks sufficient information as of March 31, 2018 to determine the financial impact of the proposed plan termination. At this time, there are no plans to terminate the Union Plan.

Note 10 – Segment Information

Our reporting structure is comprised of the following operating segments: ACS, EMS and PES. 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.

In January 2017, we acquired the principal operating assets of DSP, a custom manufacturer of silicone sheet, extrusions, stripping and compounds. We have integrated DSP into our EMS operating segment.

On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers. See Note 19, “Revenue from Contracts with Customers” for further information about this adoption. The Company sells products to fabricators and distributors who then sell directly into various end markets. Specifically, end markets within the ACS operating segment include wireless infrastructure, aerospace and defense, auto safety and connectivity, and consumer electronics. End markets within the EMS operating segment include general industrial, portable electronics, mass transit, and automotive. End markets within the PES operating segment include industrial, e-mobility, renewable energy, mass transit, and micro channel coolers. End markets in the Other operating segment include automotive and industrial. The following table presents a disaggregation of revenue from contracts with customers for the periods indicated; inter-segment sales have been eliminated from the net sales data:

Note 11 – Joint Ventures

As of March 31, 2018, we had two joint ventures, each 50% owned, which were accounted for under the equity method of accounting.

Joint Venture	Location	Operating Segment	Fiscal Year-End
Rogers INOAC Corporation (RIC)	Japan	Elastomeric Material Solutions	October 31
Rogers INOAC Suzhou Corporation (RIS)	China	Elastomeric Material Solutions	December 31

We recognized equity income related to the joint ventures of $1.0 million for the three months ended March 31, 2018 and 2017. These amounts are included in the condensed consolidated statements of operations.

The summarized financial information for the joint ventures for the periods indicated was as follows:

	Three Months Ended
	March 31,
(Dollars in thousands)	2018		2017
Net sales	$	13,367	$	11,185
Gross profit	$	5,230	$	4,311
Net income	$	2,014	$	2,018

Receivables from and payables to joint ventures arise during the normal course of business from transactions between us and the joint ventures. We had receivables of $4.6 million and $3.7 million due from RIC and RIS as of March 31, 2018 and December 31,

16

2017, respectively. We owed payables of $2.0 million and $2.1 million to RIC and RIS as of March 31, 2018 and December 31, 2017, respectively.

Note 12 – Debt

On February 17, 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).

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; or adjusted 1-month LIBOR plus 100 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.

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.

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, 2018 we have $131.0 million in outstanding borrowings under our credit facility.

At March 31, 2018, we have $2.1 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 recorded amortization expense of $0.1 million for the three months ended March 31, 2018 and 2017 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. See further discussion in 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, 2018.

Capital Leases

We have a capital lease obligation related to our manufacturing facility in Eschenbach, Germany. Under the terms of the leasing 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. The total obligation recorded for the lease as of March 31, 2018 is $5.7 million. Depreciation expense related to the capital lease was $0.1 million for each of the three-month periods ended March 31, 2018 and 2017 and these expenses are included as depreciation expense in cost of sales on our condensed consolidated statements of operations. Accumulated depreciation at March 31, 2018 and December 31, 2017 was $3.2 million and $3.3 million, respectively.

17

We also incurred interest expense on the capital lease of $0.1 million for each of the three month periods ended March 31, 2018 and 2017. Interest expense related to the debt recorded on the capital lease is included in interest expense on the condensed consolidated statements of operations.

In 2017, we entered into two additional capital lease agreements for office related equipment in various worldwide locations. The total obligation recorded for the capital leases as of March 31, 2018 was $0.7 million. Depreciation expense related to the capital leases was $0.1 million for the three months ended March 31, 2018. These expenses are included as depreciation expense in selling, general and administrative expenses on our condensed consolidated statements of operations. Accumulated depreciation as of March 31, 2018 was $0.2 million.

Gross and net carrying amounts and accumulated amortization may differ from prior periods due to foreign exchange rate fluctuations.

Amortization expense for the three months endedMarch 31, 2018 and 2017 was approximately $3.8 million and $3.3 million, respectively. The estimated future amortization expense is $11.5 million for the remainder of 2018 and $15.2 million, $11.8 million, $11.1 million and $10.7 million for 2019, 2020, 2021 and 2022, respectively.

The indefinite-lived other intangible asset was acquired as part of the acquisition of Curamik Electronics GmbH. This asset is assessed for impairment annually, and between annual assessments if an event occurs or circumstances change that indicate the carrying value may not be recoverable.

The definite-lived other intangible assets are amortized using a fair value methodology that is based on the projected economic use of the related underlying asset. The weighted average remaining amortization period as of March 31, 2018, by definite-lived other intangible asset class, is presented in the table below:

Definite-Lived Other Intangible Asset Class	Weighted Average Remaining Amortization Period

Note 14 – 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. We recorded an accrual of $3.2 million as of December 31, 2015 for remediation costs expected to be incurred based on the facts and circumstances known to us at that time. During the third quarter of 2016, the CT DEEP approved a change to our remediation plan for the site that will reduce our overall expected costs. Accordingly, we reduced the accrual by $0.9 million as a result of a change in the level of remediation that needs to take place. This benefit was recorded as an offset to selling, general, and administrative expenses in the condensed consolidated statement of operations. Remediation activities on the site are ongoing and are recorded as reductions to the accrual as they are incurred. We have incurred aggregate remediation costs of $0.6 million through March 31, 2018, and the remaining accrual for future remediation efforts is $1.7 million.

Superfund Sites

We are currently involved as a potentially responsible party (PRP) in one active case involving a waste disposal site, the Chatham Superfund Site. The costs incurred since inception for this claim have been immaterial and have been primarily covered by insurance policies, for both legal and remediation costs. In this matter, we have been assessed a cost sharing percentage of approximately 2% in relation to the range for estimated total cleanup costs of $18.8 million to $29.6 million. We believe we have sufficient insurance coverage to fully cover this liability and have recorded a liability and related insurance receivable of approximately $0.4 million as of March 31, 2018, which approximates our share of the low end of the estimated range. We believe we are a de minimis participant and, as such, have been allocated an insignificant percentage of the total PRP cost sharing responsibility. Based on facts presently known to us, we believe that the potential for the final results of this case having a material adverse effect on our results of operations, financial position or cash flows is remote. This case has been ongoing for many years and we believe that it will continue for the indefinite future. No time frame for completion can be estimated at the present time.

PCB Contamination

We have been working with CT DEEP and the United States Environmental Protection Agency, Region I, in connection with certain polychlorinated biphenyl (PCB) contamination at our facility in Woodstock, Connecticut. The issue was originally discovered in the soil at the facility in the late 1990s, which has been remediated. Further contamination was later found in the groundwater beneath the property, which was addressed with the installation of a pump and treat system in 2011. The future costs related to the maintenance of the groundwater pump and treat system now in place at the site are expected to be minimal. We believe that the remaining remediation activity will continue for several more years and no time frame for completion can be estimated at the present time.

PCB contamination at this facility was also found in the buildings and courtyards original to the site, in addition to surrounding areas, including an on-site pond. We have completed remediation activities for the buildings and courtyards. We currently have a reserve of $0.2 million for the pond remediation recorded in our condensed consolidated statements of financial position. We believe this reserve will be adequate to cover the remaining remediation work related to the pond contamination based on the information known at this time. However, if additional contamination is found, the cost of the remaining remediation may increase.

Asbestos Litigation

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 presents information about our recent asbestos claims activity:

	Three Months Ended March 31, 2018
Claims outstanding at December 31, 2017	687
New claims filed	65
Pending claims concluded	(78	)
Claims outstanding at March 31, 2018	674

19

For the three months ended March 31, 2018, 74 claims were dismissed and 4 claims were settled. Settlements totaled approximately $2.5 million for the three months ended March 31, 2018.

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. Our estimates of asbestos-related contingent liabilities and related insurance receivables are based on an independent actuarial analysis and an independent insurance usage analysis prepared annually by third parties. The actuarial analysis contains numerous assumptions, including general assumptions regarding the asbestos-related product liability litigation environment and company-specific assumptions regarding claims rates (including diseases alleged), dismissal rates, average settlement costs and average defense costs. The insurance usage analysis considers, among other things, applicable deductibles, retentions and policy limits, the solvency and historical payment experience of various insurance carriers, the likelihood of recovery as estimated by external legal counsel and existing insurance settlements.

We review our asbestos-related forecasts annually in the fourth quarter of each year unless facts and circumstances materially change during the year, at which time we would analyze these forecasts. During 2017, we reviewed the projections of our current and future asbestos claims, and determined it was appropriate to extend the liability projection period to cover all current and future claims through 2058. We based our conclusion 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 expectation of a downward trend in claims due to the average age of our claimants, which is approaching the average life expectancy. As a result, we believe we are now able to make a reasonable estimate of the actuarially determined liability for current and future asbestos claims through 2058, the expected end of our asbestos liability exposure.

As of December 31, 2017, the balances of the asbestos-related claims and insurance receivables, which are projected to cover all current and future claims through 2058, were $76.2 million and $69.2 million, respectively. 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. During the first quarter of 2018, we received notice that primary coverage for a period of eight years and excess coverage for a period of two years had been exhausted, and as a result, we incurred indemnity and defense costs of $0.3 million. These costs reduced our existing asbestos-related liabilities to $75.9 million as of March 31, 2018. 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.

We believe that it is reasonably possible that we may incur additional charges for our asbestos liabilities and defense costs in the future, which could exceed existing reserves and insurance recovery.

The amounts recorded for the asbestos-related liabilities and the related insurance receivables described above were 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.

There can be no assurance that our accrued asbestos liabilities will approximate our actual asbestos-related settlement and defense costs, or that our accrued insurance recoveries will be realized. We believe that it is reasonably possible that we may incur additional charges for our asbestos liabilities and defense costs in the future, which could exceed existing reserves and insurance recovery. We will continue to vigorously defend ourselves and believe we have substantial unutilized insurance coverage to mitigate future costs related to this matter.

General Litigation

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, after taking into account insurance coverage and the aforementioned accruals, will have a material adverse impact on our results of operations, financial position or cash flows.

Note 15 – Share Repurchase

On August 6, 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. As of March 31, 2018, $49.0 million remained available for repurchase under the Program.

We repurchased the following shares of capital stock during the quarter ended March 31, 2018:

(Dollars in thousands)	Three Months Ended March 31, 2018
Shares of capital stock repurchased	23,138
Value of capital stock repurchased	$	2,999

All repurchases were made using cash from operations.

Note 16 – Income Taxes

Our effective income tax rate was 15.4% and 32.3% for the three months ended March 31, 2018 and 2017, respectively. The decrease was primarily due to a lower U.S. effective tax rate, as a result of U.S. tax reform, changes in pretax income mix across jurisdictions with disparate tax rates, excess tax deductions on stock based compensation, R&D credits and a release of reserves for uncertain tax positions, partially offset by an increase in current year accruals for uncertain tax positions.

The total amount of unrecognized tax benefits as of March 31, 2018 was $11.8 million, of which $10.3 million would affect our effective tax rate if recognized. It is reasonably possible that approximately $3.7 million of our unrecognized tax benefits as of March 31, 2018 will reverse within the next twelve months.

We recognize interest and penalties related to unrecognized tax benefits through income tax expense. As of March 31, 2018, we had $0.7 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 2013.

Note 17 – Restructuring and Impairment Charges

In the second quarter of 2017, we completed the physical relocation of our global headquarters from Rogers, Connecticut to Chandler, Arizona. We recorded $0.4 million and $0.7 million of expense related to this project in the three months ended March 31, 2018 and 2017, respectively. Severance activity related to the headquarters relocation is presented in the table below for the three month-period ended March 31, 2018:

(Dollars in thousands)	Severance Related to Headquarters Relocation
Balance at December 31, 2017	$	183
Provisions	53
Payments	(157		)
Balance at March 31, 2018	$	79

The fair value of the total severance benefits to be paid (including payments already made) in connection with the relocation is $1.1 million, of which we expensed $0.1 million in the first quarter of 2018. The total severance costs are being expensed ratably over the required service period for the affected employees.

Note 18 – Assets Held for Sale

In the second quarter of 2017, we began actively marketing for sale unutilized property in Chandler, Arizona, consisting of a building and two adjacent parcels of land with an aggregate net book value of $0.9 million. The assets are classified as held for sale and are no longer being depreciated.

Note 19 – Revenue from Contracts with Customers

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, to achieve a consistent application of revenue recognition, resulting in a single revenue model to be applied by reporting companies under U.S. generally accepted accounting principles. Under the new model, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the providing entity expects to be entitled in exchange for those goods or services. In addition, the new standard requires that reporting companies disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.

We recognize revenue when all of the following criteria are met: (1) we have entered into a binding agreement, (2) the performance obligations have been identified, (3) the transaction price to the customer has been determined, (4) the transaction price has been allocated to the performance obligations in the contract, and (5) the performance obligations have been satisfied. The majority of our shipping terms permit us to recognize revenue at point of shipment. Some shipping terms require the goods to be through customs or be received by the customer before title passes. In those instances, revenue is not recognized until either the customer has received the goods or they have passed through customs, depending on the circumstances. Shipping and handling costs are treated as fulfillment costs. Sales tax or VAT are excluded from the measurement of the transaction price.

The Company manufactures some products to customer specifications which are customized to such a degree that it is unlikely that another entity would purchase these products or that we could modify these products for another customer. These products are deemed to have no alternative use to the Company whereby we have an enforceable right to payment evidenced by contractual termination clauses. In accordance with ASC 606, for those circumstances we recognize revenue on an over-time basis. Revenue recognition does not occur until the product meets the definition of “no alternative use” and therefore, items that have not yet reached that point in the production process are not included in the population of items with over-time revenue recognition.

As appropriate, we record estimated reductions to revenue for customer returns, allowances, and warranty claims. Provisions for such reductions are made at the time of sale and are typically derived from historical trends and other relevant information.

Performance Obligations

Manufactured goods are our primary performance obligations. Revenue related to our performance obligations is predominantly recognized at a point in time consistent with our shipping terms. For certain products that meet the criteria of no alternative use whereby the Company has the right to payment, we recognize revenue on an over-time basis.

The selection of a method to measure progress toward completion of a contract requires judgment and is based on the nature of the products or services to be provided. We use the cost incurred method to measure the progress of our contracts with no alternative use products whereby the Company has the right to payment as we believe it is the best depiction of the transferring of value to the customer. Under the cost incurred method, the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the contract. Contract costs include labor, materials and subcontractors costs, as well as an allocation of indirect costs. Revenues, including estimated fees or profits, are recorded as costs are incurred.

Performance obligations are typically satisfied within three months of receipt of a customer order; therefore, a change in cost estimates will not have a material impact on the percentage of completion noted at the prior quarter end. Our typical payment terms with customers range from 30 days to 105 days. Product pricing is determined and negotiated on a standalone basis. Product pricing is determined without consideration for the pricing, margin, or other information specific to other products that the same customer or other parties related to that customer may also purchase, whether in the same or a different contract. Management allocates the transaction price to its performance obligations primarily based on stand-alone selling prices that may have been developed via specific customer quote for no alternative use products and non-standard products or standard price lists for standard products. The accounting for the estimate of variable consideration is consistent with our current practice.

Contract modifications occur when there is a change to the products, price, or both. Contract modifications are treated as a separate contract if there are additions to promised goods and services that are distinct and if the price for that separate performance obligation reflects the stand-alone selling price for those goods or services. However, if the obligations in the contract modification are not distinct and are part of a single performance obligation that is only partially satisfied, the contract is not determined to be a separate contract and is accounted for as a revision to an existing contract. These modifications are accounted for prospectively when remaining promises are distinct from those previously transferred, or through a cumulative catch-up adjustment.

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, 2018.

22

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

	March 31, 2018
(Dollars in thousands)	Advanced Connectivity Solutions	Elastomeric Material Solutions	Power Electronics Solutions	Other	Total
Contract Assets	—	308	17,753	3,979	22,040

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

Transition

We adopted ASU 2014-09 in the first quarter of 2018 retrospectively with the cumulative effect of applying the standard recognized at the date of implementation and without restatement of comparative periods. This application of the new standard resulted in an increase to the January 1, 2018 balance of retained earnings of approximately $4.2 million, net of tax.

The guidance was applied to all contracts that were not completed at the date of implementation. The primary reason for the impact of adoption is due to over-time revenue recognition.

If the criteria for over-time recognition are not met, revenue is recognized at a point in time. In considering at what point in time control of the product or service has transferred to the customer, we consider qualitative factors such as: 1) present right to payment; 2) legal title to the asset; 3) physical possession; 4) risks and rewards of ownership; and, 5) customer acceptance.

The impact of adoption using the modified retrospective method on the Company’s condensed consolidated financial statements is as follows:

	As of
Condensed Consolidated Statements of Financial Position:	December 31, 2017					January 1, 2018
(Dollars in thousands)	Under ASC 605		Impact of Adoption			Under ASC 606
Contract assets	$	—	$	18,099		$	18,099

Deferred income taxes	10,706		1,580			12,286
Retained earnings	684,540		4,212			688,752

23

The following tables set forth the amount by which each financial statement line item is affected in the current reporting period by the application of ASC 606, as compared to the guidance that was in effect before its adoption. The impact of adoption on the condensed consolidated financial statements as of and for the three months ended March 31, 2018 is as follows:

Practical Expedients

The Company will recognize the incremental costs of obtaining a contract as an expense when incurred as the amortization period of the asset is expected to be one year or less. The Company will not adjust the promised amount of consideration for the effects of a significant financing component as we expect, at contract inception, that the period between when the transfer of goods to our customer occurs and when the customer fully pays for the goods will be one year or less. We do not disclose the Company’s unsatisfied performance obligations as they are part of contracts that have an original expected duration of one year or less.

In the first quarter of 2018, we recorded a gain from the settlement of antitrust litigation in the amount of $3.6 million as a result of the settlement of a class action lawsuit, filed in 2005, which alleged that Dow Chemical Company and other urethane raw material suppliers unlawfully agreed to fix, raise, maintain or stabilize the prices of Polyether Polyol Products sold in the United States from January 1, 1999 through December 31, 2004 in violation of the federal antitrust laws. We recorded a receivable for this claim and received payment in April 2018.

In the first quarter of 2017, we completed the planned sale of a parcel of land in Belgium that had been classified as held for sale as of December 31, 2016 and recognized a gain on sale of approximately $0.9 million.

Note 21 – Recent Accounting Standards

In March 2018, the Financial Accounting Standards Board (FASB) issued ASU No. 2018-05, Income Taxes (Topic 740):Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. This ASU adds guidance that answers questions regarding how certain income tax effects from the Tax Cuts and Jobs Act (the Act) should be applied to companies’ financial statements. The guidance also lists which financial statement disclosures are required under a measurement period approach.

In February 2018, the FASB issued ASU No. 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 the Act from accumulated other comprehensive income to retained earnings. This ASU is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the method and impact the adoption of ASU 2018-02 will have on the Company’s consolidated financial statements and disclosures.

In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income (GILTI) provisions of the Act. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or to treat any taxes on GILTI inclusions as period costs are both acceptable methods subject to an accounting policy election. Effective in the first quarter of 2018, the Company has elected to treat any potential GILTI inclusions as a period cost.

In December 2017, Staff Accounting Bulletin No. 118 (SAB 118) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, we recorded provisional estimates for the deferred tax expense recorded in connection with the remeasurement of certain deferred tax assets and tax expense associated with the mandatory deemed repatriation of foreign earnings at December 31, 2017. Management has continued to gather and analyze information associated with these provisional estimates and did not record any adjustments during the three months ended March 31, 2018. Any subsequent adjustment to these amounts will be recorded to tax expense in the quarter of 2018 when the analysis is complete.

In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. ASU No. 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017. Adoption of this standard will be applied prospectively to awards modified on or after the adoption date. The impact of this new standard will depend on the extent and nature of future changes to the terms and conditions of the Company’s share-based payment awards. The Company adopted this standard on January 1, 2018, which did not have a material effect on the condensed consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost. The changes to the standard require employers to report the service cost component in the same line item as other compensation costs arising from services rendered by employees during the reporting period. The other components of net periodic pension benefit costs will be presented in the statement of operations separately from the service cost and outside of a subtotal of operating income from operations. In addition, only the service cost component may be eligible for capitalization where applicable. ASU 2017-07 is effective for annual periods beginning after December 15, 2017. The Company adopted this standard on January 1, 2018. In conjunction with the adoption of this guidance,

25

the Company reclassified $0.4 million in net periodic pension benefits from Selling, general and administrative expenses to Other income (expense), net for the three months ended March 31, 2017.

In February 2016, the FASB issued ASU No. 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 No. 2016-02 supersedes the existing guidance on accounting for leases. The standard is effective for interim and annual reporting periods for fiscal years beginning after December 15, 2018. Early adoption of this standard is permitted and it is to be adopted using a modified retrospective approach. The Company has established an inventory of existing leases and is in the process of evaluating the classification of each lease and quantifying the accounting impact in accordance with the new standard. The Company expects to adopt this accounting standard beginning in fiscal year 2019.

Note 22 – Subsequent Events

Facility Consolidation

On April 24, 2018, we made the decision to relocate our Santa Fe Springs, California operations to the Company’s facilities in Carol Stream, Illinois and Bear, Delaware. We expect to incur restructuring expenses of approximately $2.0 million in connection with the closure and transfer of production capabilities to the Carol Stream facility. These costs include approximately $0.8 million in severance and retention expenses and $1.2 million of costs related to the relocation of equipment. The Company estimates that approximately $1.5 million and $0.5 million of the costs will be incurred in fiscal years 2018 and 2019, respectively.Completion of the transfer, and start-up of production at other Company facilities, is expected to require capital expenditures of approximately $1.2 million to $1.4 million.

Sale of Property

In February 2018, we signed an agreement for the sale of a building and one parcel of land for an aggregate sales price of $1.1 million. The assets were classified as held for sale with an aggregate net book value of approximately $0.5 million as of March 31, 2018. The sale transaction closed in April 2018.

2018First Quarter Executive Summary

In the first quarter of 2018 as compared to the first quarter of 2017, our net sales increased 5.3% to $214.6 million, gross margin decreased373 basis points to 35.7%, and operating margin decreased469 basis points. The following key factors should be considered when reviewing our results of operations, financial condition and liquidity for the periods discussed:

• Our net sales increase in the first quarter of 2018 reflected currency fluctuations and growth attributable to our EMS and PES operating segments. Net sales were favorably impacted by $9.4 million due to currency fluctuations in the Euro, Renminbi and Korean Won relative to the U.S. dollar. Our EMS operating segment had higher demand in electric and hybrid electric vehicles, portable electronics, general industrial, and automotive and our PES operating segment had higher demand in renewable energy, variable frequency drives and laser diode coolers. These improvements were partially offset by a decline in net sales in our ACS operating segment due to lower demand for wireless 4G LTE applications, portable electronics, satellite TV and aerospace and defense. Net sales were favorably impacted by $3.9 million as a result of the adoption of new accounting guidance for revenue recognition. See Note 19, “Revenue from Contracts with Customers,” as well as “Segment Sales and Operations” for further discussion.

• Our gross margin decreased373 basis points and our operating margin decreased469 basis points in the first quarter of 2018. Our gross margin deteriorated to 35.7% in the first quarter of 2018 as a result of increased costs for commodities and product launch, as well as lower capacity utilization including performance challenges with process issues, machine downtime and unfavorable absorption of fixed costs.

• Our operating incomedecreased to $31.0 million in the first quarter of 2018, as compared to $39.0 million in the first quarter of 2017, reflecting an increase in selling, general & administrative (SG&A) expenses due to a $0.6 million increase in intangible assets amortization, a $1.0 million increase in severance, a $0.9 million increase in incentive compensation and a $2.1 million increase in sales and marketing costs associated with strategic growth initiatives. As a result, SG&A expense increased as a percentage of net sales from 17.0% in the first quarter of 2017 to 18.9% in the first quarter of 2018.

• We are an innovation company, and in the first quarter of 2018 we continued our investment in research and development (R&D), with R&D expenses comprising 3.8% of our quarterly net sales. R&D expenses were $8.1 million in the first quarter of 2018, which was an increase of $1.2 million and 0.4% as a percentage of net sales from the first quarter of 2017. We have made concerted efforts to realign our R&D organization to better fit the future direction of our Company, including dedicating resources to focus on current product extensions and enhancements to meet our short-term and long-term technology needs.

Net Sales and Gross Margin	Quarter Ended
(Dollars in thousands)	March 31, 2018			March 31, 2017			Percent Change
Net sales	$	214,611		$	203,828		5.3%
Gross margin	35.7		%	39.4		%

Net sales increased by 5.3% in the first quarter of 2018 compared to the first quarter of 2017. Net sales were favorably impacted by 4.6% due to currency fluctuations in the Euro, Renminbi and Korean Won relative to the U.S. dollar. The increase in net sales was further driven by higher organic net sales in our EMS and PES operating segments. EMS net sales increased 1.6% due in part to higher end-market demand in portable electronics, automotive, and general industrial, offset by decreased demand in mass transit applications. PES had increased net sales of 35.3% due in part to higher end-market demand in renewable energy, electric and hybrid electric vehicles, variable frequency motor drives and laser diode cooler applications. The ACS operating segment had a decrease in net sales of 6.5% due to lower end-market demand in aerospace and defense, wireless infrastructure applications and portable electronics, partially offset by higher demand in automotive radar.

See “Segment Sales and Operations” below for further discussion on segment performance.

Gross margin as a percentage of net sales decreased373 basis points to 35.7% in the first quarter of 2018 compared to 39.4% in the first quarter of 2017. Gross margin in the first quarter of 2018 was unfavorably impacted by increased costs for commodities and product launch, as well as lower capacity utilization including performance challenges with process issues, machine downtime and unfavorable absorption of fixed costs.

Selling, General and Administrative Expenses	Quarter Ended
(Dollars in thousands)	March 31, 2018			March 31, 2017			Percent Change
Selling, general and administrative expenses	$	40,597		$	34,569		17.4%
Percentage of net sales	18.9		%	17.0		%

SG&A expenses increased 17.4% in the first quarter of 2018 from the first quarter of 2017, primarily due to a $2.1 million increase in costs associated with strategic investments, a $1.0 million increase in severance expense, a $0.9 million increase in incentive compensation expense, and a $0.6 million increase in other intangible assets amortization. SG&A increased as a percent of net sales to 18.9% in the first quarter of 2018 from 17.0% in the first quarter of 2017.

Percentage of net sales	3.8		%	3.4		%

R&D expenses increased 16.9% in the first quarter of 2018 from the first quarter of 2017. The increases are due to continued investments that are targeted at developing new platforms and technologies focused on long-term growth initiatives at our innovation centers in the U.S., Europe and Asia.

Restructuring and Impairment Charges and Other Operating Expenses (Income), Net	Quarter Ended
(Dollars in thousands)	March 31, 2018			March 31, 2017			Percent Change
Restructuring and impairment charges	$	422		$	725		(41.8)%
Other operating (income) expense, net	$	(3,591	)	(942		)	281.2%

In the first quarter of 2018, we recognized $0.4 million of restructuring charges associated with the relocation of our global headquarters from Rogers, Connecticut to Chandler, Arizona compared to $0.7 million recognized in the first quarter of 2017. These charges consist of severance expense and other costs associated with relocating employees to Arizona.

We expect to incur restructuring expenses of approximately $2.0 million in connection with the closure and transfer of production capabilities to the Carol Stream and Bear facilities, as discussed in Note 22, “Subsequent Events.” These costs include approximately $0.8 million in severance and retention expenses and $1.2 million of costs related to the relocation of equipment. We expect that approximately $1.5 million and $0.5 million of the costs will be incurred in fiscal years 2018 and 2019, respectively.

In the first quarter of 2018 we recognized other operating income of $3.6 million related to the settlement of an antitrust litigation claim, for which we had recorded a receivable as of March 31, 2018. In the first quarter of 2017, we recognized other operating income of $0.9 million as a result of the planned sale of a parcel of land in Belgium that had been classified as held for sale as of December 31, 2016.

Equity Income in Unconsolidated Joint Ventures	Quarter Ended
(Dollars in thousands)	March 31, 2018		March 31, 2017		Percent Change

Equity income in unconsolidated joint ventures decreased 0.2% in the first quarter of 2018 from the first quarter of 2017.

Other Income (Expense), Net	Quarter Ended
(Dollars in thousands)	March 31, 2018		March 31, 2017		Percent Change
Other income (expense), net	$	66	$	1,119	(94.1)%

Other income in the first quarter of 2018 decreased from the first quarter of 2017 due to declines in the value of our copper derivatives and foreign currency transaction costs. Copper derivative costs were $0.8 million in the first quarter of 2018 compared to gains of $0.2 million in the first quarter of 2017. Foreign currency transaction costs were $0.1 million in the first quarter of 2018 and were flat in the first quarter of 2017.

Interest Expense, Net	Quarter Ended
(Dollars in thousands)	March 31, 2018			March 31, 2017			Percent Change
Interest expense, net	$	(1,210	)	$	(1,248	)	(3.0)%

Interest expense, net, decreased by 3.0% in the first quarter of 2018 from the first quarter of 2017 due to lower average outstanding balances on our credit facilities due to the discretionary payments of $50.0 million and $60.0 million, during the second and third quarters of 2017, respectively, to reduce our outstanding borrowings under our credit facility.

Income Taxes	Quarter Ended
(Dollars in thousands)	March 31, 2018			March 31, 2017			Percent Change
Income tax expense	$	4,771		$	12,885		(63.0)%
Effective tax rate	15.4		%	32.3		%

Our effective income tax rate was 15.4% and 32.3% for the three months ended March 31, 2018 and 2017, respectively. The decrease was primarily due to a lower U.S. effective tax rate, as a result of U.S. tax reform, changes in pretax income mix across jurisdictions with disparate tax rates, excess tax deductions on stock based compensation, R&D credits and a release of reserves for uncertain tax positions partially offset by an increase in current year accruals for uncertain tax positions.

The ACS operating segment is comprised of high frequency circuit material products used for making circuitry that receives, processes and transmits high frequency communications signals, in a wide variety of markets and applications, including wireless communications, automotive, high reliability, wired infrastructure, aerospace and defense, and consumer applications, among others.

Q1 2018 versus Q1 2017

Net sales in this segment decreased by 6.5% in the first quarter of 2018 compared to the first quarter of 2017. The decrease in net sales over the first quarter of 2017 was unfavorably impacted by lower demand for wireless infrastructure applications of 14.7%, and aerospace and defense of 2.2%, offset in part by higher demand in automotive radar applications of 21.1%. Currency fluctuations had a $1.8 million favorable impact on net sales due to the appreciation in value of the Euro, Renminbi and Korean Won relative to the U.S. dollar.

Operating income decreased by 59.5% in the first quarter of 2018 from the first quarter of 2017. As a percentage of net sales, operating income in the first quarter of 2018 was 10.8%, as compared to the 24.8% reported in the first quarter of 2017. This decrease is primarily due to lower net sales as well as increased costs for copper commodities and product launch, increases in SG&A expense and R&D expense, as well as lower capacity utilization including performance challenges with process issues, machine downtime and unfavorable absorption of fixed costs.

The EMS operating segment is comprised of polyurethane and silicone foam products, which are sold into a wide variety of applications and markets, including general industrial, portable electronics, automotive, mass transit and consumer applications. In January 2017, we acquired the principal operating assets of DSP, a custom silicone product development and manufacturing business, serving a wide range of high reliability applications. We have integrated DSP into our EMS operating segment.

Q1 2018 versus Q1 2017

Net sales in this segment increased by 1.6% in the first quarter of 2018 compared to the first quarter of 2017. Net sales were favorably impacted by currency fluctuations of $2.0 million primarily as a result of the appreciation in value of the Euro and Renminbi relative to the U.S. dollar. The increase in net sales was also impacted by higher demand in portable electronics of 8.5%, electric and hybrid electric vehicles of 6.8% and general industrial of 2.7%, but it was more than offset by lower demand in mass transit applications of 15.3% and other applications of 27.9%.

Operating income increased by 10.7% in the first quarter of 2018 from the first quarter of 2017. As a percentage of net sales, first quarter of 2018 operating income was 18.1%, a 149 basis point increase as compared to the 16.6% reported in the first quarter of 2017. This increase is primarily due a $3.6 million gain on settlement from antitrust class action litigation, as discussed in Note 20, “Supplemental Financial Information,” and a decrease in acquisition and integration expenses.

The PES operating segment is comprised of two product lines - curamik^® direct-bonded copper (DBC) substrates that are used primarily in the design of intelligent power management devices, such as IGBT (insulated gate bipolar transistor) modules that enable a wide range of products including highly efficient industrial motor drives, wind and solar energy converters and electrical systems in automobiles, and ROLINX^® busbars that are used primarily in power distribution systems products in electric and hybrid electric vehicles and clean technology applications.

Q1 2018 versus Q1 2017

Net sales in this segment increased by 35.3% in the first quarter of 2018 from the first quarter of 2017. Net sales were positively impacted by higher demand for electric and hybrid electric vehicles of 178.4%, renewable energy of 58%, laser diode coolers of 26.8% and variable frequency motor drives of 12.4%. Net sales in this segment were favorably impacted by $4.3 million as a result of the adoption of new accounting guidance for revenue recognition. See Note 19, “Revenue from Contracts with Customers” for additional information. Net sales were favorably impacted by $5.3 million due to currency fluctuations, primarily as a result of the appreciation in value of the Euro relative to the U.S. dollar.

Operating income for the quarter increased by 44.9% in the first quarter of 2018 from the first quarter of 2017. As a percentage of net sales, first quarter of 2018 operating income was 12.2%, an 81 basis point increase as compared to the 11.4% reported in the first quarter of 2017. This increase is primarily due to higher net sales from increased demand partially offset by unfavorable performance due to process issues and capacity optimization efforts, higher commodity costs, and increased sales and marketing costs associated with strategic growth initiatives.

Our Other operating segment consists of our elastomer rollers and floats business, as well as our inverter distribution business.

Q1 2018 versus Q1 2017

Net sales decreased by 7.3% in the first quarter of 2018 from the first quarter of 2017. Net sales in this segment were unfavorably impacted by $0.4 million as a result of the adoption of new accounting guidance for revenue recognition. See Note 19, “Revenue from Contracts with Customers” for additional information. Currency fluctuations had a negligible impact on net sales.

Operating income increased 2.9% in the first quarter of 2018 compared to the first quarter of 2017. As a percentage of net sales, operating income increased to 36.6% in the first quarter of 2018 from 32.9% in the first quarter of 2017. This increase was primarily driven by operational improvements and efficiency initiatives.

Liquidity, Capital Resources and Financial Position

We believe that our existing sources of liquidity and cash flows that are expected to be generated 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. We regularly review and evaluate the adequacy of our cash flows, borrowing facilities and banking relationships seeking to ensure that we have the appropriate access to cash to fund both our near-term operating needs and our long-term strategic initiatives.

(Dollars in thousands)	March 31, 2018		December 31, 2017
Key Balance Sheet Accounts:
Cash and cash equivalents	$	173,019	$	181,159
Accounts receivable, net	$	150,038	$	140,562
Contract assets	$	22,040	$	—
Inventories	$	107,935	$	112,557
Outstanding borrowing on credit facilities	$	130,982	$	130,982

At March 31, 2018, cash and cash equivalents were $173.0 million as compared to $181.2 million at the end of 2017, a decrease of $8.1 million, or 4.5%. This decrease was primarily due to $9.1 million in capital expenditures, $6.4 millionin tax payments related to net share settlement of equity awards and$3.0 millionin repurchases of capital stock, partially offset by cash generated by operations.

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

(Dollars in thousands)	March 31, 2018		December 31, 2017
United States	$	35,628	$	35,653
Europe	43,147		41,307
Asia	94,244		104,199
Total cash and cash equivalents	$	173,019	$	181,159

Approximately $137.4 million of our cash and cash equivalents were held by non-U.S. subsidiaries as of March 31, 2018. As a result of U.S. tax reform, unremitted earnings as of December 31, 2017 were subjected to U.S. tax through the transition tax, but a portion could be subject to additional foreign income taxes if they are redeployed outside of their country of origin. With the exception of certain of our Chinese subsidiaries, we have historically asserted and continue to assert that foreign earnings are indefinitely reinvested. While we have not changed our assertion with respect to foreign earnings compared to prior years, we are currently evaluating the impact of U.S. tax reform on our global structure and any associated impacts it may have on our assertion on a go forward basis, and as such have not changed our assertion with respect to distribution of earnings that would require the accrual of additional deferred income taxes.

Significant changes in our balance sheet accounts from December 31, 2017 to March 31, 2018 were as follows:

• Accounts receivable increased6.7% to $150.0 million as of March 31, 2018, from $140.6 million at December 31, 2017. The increase from year-end was primarily due to higher net sales in the first quarter of 2018 compared to the fourth quarter of 2017 as well as an increase due to a receivable in the amount of $3.6 million for settlement of an antitrust litigation claim.

• We recorded contract assets of $22.0 million as of March 31, 2018 in conjunction with the adoption of ASU 2014-09. See further discussion in Note 19, “Revenue from Contracts with Customers” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q.

• Inventory decreased4.1% to $107.9 million as of March 31, 2018, from $112.6 million at December 31, 2017 as a result of the adoption of new accounting guidance for revenue recognition. See discussion in Note 19, “Revenue from Contracts with Customers.”

• Accrued employee benefits and compensation decreased to $26.2 million of March 31, 2018, from $39.4 million at December 31, 2017. This decrease is primarily due to incentive compensation payouts of $17 million that occurred in the first quarter of 2018, partially offset by $2.7 million of accruals for projected incentive compensation payouts for the current performance year.

During the three months ended March 31, 2018, we repurchased 23,138 shares of our capital stock for $3.0 million under a $100.0 million share repurchase program approved by our Board of Directors on August 6, 2015. The share repurchase program

33

has no expiration date and may be suspended or discontinued at any time without notice. As of March 31, 2018, $49.0 million remained for repurchase under our share repurchase program. All purchases were made using cash from operations.

On February 17, 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).

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, 2018 we have $131.0 million in outstanding borrowings under our credit facility.

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, 2018.

During the first quarter of 2018, there were not any material new developments related to our capital leases. Refer to Note 12, “Debt” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q for further discussion on liquidity matters.

Contingencies

During the first quarter of 2018, we did not become aware of any material new developments related to environmental matters or other contingencies or incur any material costs or capital expenditures related to environmental matters. Refer to Note 14, “Commitments and Contingencies” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q for further discussion on ongoing environmental and other contingencies.

Off-Balance Sheet Arrangements

As of March 31, 2018, we did not have any off-balance sheet arrangements that have or are, in the opinion of management, likely to have a current or future material effect on our financial condition or results of operations.

Critical Accounting Policies

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, to achieve a consistent application of revenue recognition, resulting in a single revenue model to be applied by reporting companies under U.S. generally accepted accounting principles. With the adoption of ASU 2017-09, we recognize revenue when all of the following criteria are met: (1) we have entered into a binding agreement, (2) the performance obligations have been identified, (3) the transaction price to the customer has been determined, (4) the transaction price has been allocated to the performance obligations in the contract, and (5) the performance obligations have been satisfied. The majority of our shipping terms permit us to recognize revenue at point of shipment. Some shipping terms require the goods to be through customs or be received by the customer before title passes. In those instances, revenue is not recognized until either the customer has received the goods or they have passed through customs, depending on the circumstances. Shipping and handling costs are treated as fulfillment costs. Sales tax or VAT are excluded from the measurement of the transaction price.

Recent Accounting Pronouncements

See Note 21, “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 significant changes in our exposure to market risk during the first quarter of 2018. 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, 2018. 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, 2018.

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. This evaluation included the operations of Diversified Silicone Products, Inc., which we acquired on January 6, 2017.

The share repurchase program has no expiration date and may be suspended or discontinued at any time without notice. As of March 31, 2018, $49.0 million remained for repurchase under the share repurchase program. All repurchases were made using cash from operations. Our stock repurchases may occur from time to time through open market purchases, privately negotiated transactions or plans designed to comply with Rule 10b5-1 promulgated under the Securities Exchange Act of 1934, as amended.

GENERAL RELEASE AND SEPARATION AGREEMENT

This General Release and Separation Agreement (hereinafter “Agreement”) is made as of March 17, 2018 (the “Effective Date”) by and between Janice Stipp (hereinafter “Executive”) and Rogers Corporation (hereinafter “Rogers” or the “Company”). The purpose of this Agreement is to fully and finally dispose of all issues regarding Executive’s employment and separation from employment with Rogers as described below.

1.    The Executive shall be separated from employment with Rogers on May 16, 2018 (the “Separation Date”). Such period following execution of this Agreement through the Separation Date shall be the “Transition Period.” During the Transition Period, Executive shall be paid Executive’s base salary and benefits (“Transition Benefits”) and shall perform such limited transition duties as set forth in Exhibit A (“Transition Duties”). Executive shall retain access to Executive’s office and Company email account during the Transition Period.

2.Compensation Benefits. In consideration for entering into this Agreement and pursuant to paragraph 6 of the Offer Letter between Executive and Rogers (the “Offer Letter”), following the Separation Date, Rogers will provide the following payments (“Compensation Benefits”) in return for the release and waiver set forth herein and the satisfactory fulfillment by Executive of all Executive’s agreements hereunder:

(a)    pursuant to paragraph 6 of the Offer Letter, compensation in the form of fifty-two (52) weeks (the “Compensation Period”) of base pay, annualized at four hundred and thirty thousand ($430,000 USD) paid in recurring amounts consistent with Rogers’ regular payroll practices (provided that the first installment shall not be paid prior to the first possible payroll cycle after this Agreement becomes non-revocable), with appropriate withholding with respect to taxes and deductions;

(b)    pursuant to paragraph 6 of the Offer Letter, bonus under the AICP for the 2018 fiscal year of two hundred seventy-nine thousand five hundred ($279,500 USD), with Executive’s individual payment being determined on the basis of Executive’s target bonus percentage as approved by the Compensation Committee with respect to the 2018 fiscal year, with appropriate withholding with respect to taxes, to be paid in a lump sum following the Separation Date; and

(c)      a lump sum payment equal to $820,000, less applicable taxes and withholdings, payable following the completion of the Consulting Period as defined below.

Exhibit 10.1

3.Consulting Period. During the six-month period following the Separation Date (the “Consulting Period”), Executive shall remain available, as an independent contractor, to perform additional consulting services from time to time as requested by Rogers. Such services shall be limited to providing advice and support to Rogers through preparation for and participation in meetings or teleconferences requested or arranged by any of Rogers’ Chief Executive Officer, Chief Financial Officer or General Counsel regarding the Company’s finance, treasury, accounting, corporate development or investor relations functions. Such services shall generally be provided by Executive from Executive’s own remote work location, but to the extent that Executive performs any services on the Company's premises or using the Company's equipment, Executive shall comply with all applicable policies of the Company relating to business and office conduct, health and safety, and use of the Company's facilities, supplies, information technology, equipment, networks, and other resources. The obligations relating to “Proprietary Information” pursuant to the Employment, Invention, Confidentiality and Non-Compete Agreement with Rogers, dated November 9, 2015 (the “Non-Compete Agreement”) shall continue to apply to Executive during the Consulting Period. As full compensation for the consulting services and rights granted to the Company under this Section 3, the Company shall pay a total of two hundred and fifteen thousand dollars ($215,000 USD) to Executive in equal monthly installments of thirty five thousand eight hundred thirty three dollars and thirty three cents ($35,833.33 USD) on or about the fifteenth (15^th) of each month beginning June 15, 2018.

4.COBRA Subsidy. Executive shall be entitled to continue participating in the Company’s medical, prescription drug, vision and dental plans for Executive and family, under her current plan election, through December 31, 2018 (the "COBRA Benefits") subject to the terms of the applicable plans and as follows: (i) such COBRA Benefits shall be subject to Executive’s timely election of continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, as applicable; (ii) the Company will pay the company contribution and Executive shall be required to pay the employee contribution, in each case determined as if Executive remained an active employee of the Company; (iii) Executive’s right to receive further COBRA Benefits shall terminate if and when Executive elects and secures alternative health benefits from a new employer, of which Executive shall promptly notify the Company, or if and when Executive otherwise becomes ineligible for further coverage under COBRA; and (iv) the Company shall be required to provide the COBRA Benefits only to the extent that the Company continues offering an employee health benefits plan and to the extent that the Company is not required to provide and pay for such post-termination coverage to other employees to avoid a violation of applicable nondiscrimination requirements.

5.General Release. Executive, on behalf of Executive and Executive's descendants, ancestors, dependents, heirs, executors, administrators, assigns, and successors, and each of them, hereby covenants not to sue and fully releases, acquits, and discharges Rogers and its parent(s), subsidiaries, affiliates, related LLCs, owners, trustees, directors, officers, agents, servants, employees, stockholders, representatives, assigns, and successors (collectively referred to as “Released Parties”) with respect to and from any and all claims, wages, agreements, contracts, covenants, actions, suits, causes of action, expenses, attorney's fees, damages, and liabilities of whatever kind or nature in law, equity or otherwise, whether known or unknown, suspected or unsuspected, and whether or not concealed or hidden, which Executive has at any time heretofore

8

Exhibit 10.1

owned or held against said Released Parties, including, without limitation, those arising out of or in any way connected with Executive's employment relationship with the Company or Executive’s separation from employment at the Company. This general release includes claims discrimination or retaliation under Title VII of the Civil Rights Act of 1964, as amended, 42 U.S.C. § 2000 et seq., the Employee Retirement Income Security Act of 1974, 29 U.S.C. § 1001 et seq., the Americans with Disabilities Act, 42 U.S.C. § 12101 et seq., the Connecticut Fair Employment Practices Act, Conn. Gen. Stat. § 46 (a) - 51 et seq.        Executive agrees that by this Agreement, Executive is expressly waiving Executive’s right to bring or pursue any judicial action, any contractual action, any statutory action or procedure or any action which Executive could have brought with respect to any matter arising from Executive’s employment with Rogers and separation therefrom with Rogers, provided, however, that this Agreement shall not preclude Executive from seeking unemployment compensation or workers’ compensation benefits, nor shall it constitute a waiver with respect to any claims Executive may have for retirement benefits (e.g., 401(k) and pension benefits); provided, however, Executive meets all applicable requirements under applicable retirement plans and no statement by either party shall modify such plans unless expressly done so in writing pursuant to the plan terms. Executive also agrees that by entering into this Agreement, Executive is waiving any right Executive may have to seek or accept damages or relief of any kind with respect to the claims released by this Agreement or by reason of termination of Executive’s employment. Executive further agrees to execute and deliver to the Company an update to this release and waiver in form and substance satisfactory to the Company to be effective for the period through the Separation Date.

6.Non-disparagement. The parties covenant and agree that they will not at any time, directly, indirectly or, in the case of Executive, through any entity in which Executive is an officer, director, employee, consultant, or shareholder, either orally, in writing, or through any medium (including, but not limited to, television or radio, newspapers, magazines, computer networks, social media, or bulletin boards, or any other form of communication), disparage, defame, impugn, or otherwise damage or assail the reputation, integrity or professionalism of the other party, or any officer, director, employee, agent or representative of Rogers. Nothing in this Section 6 is intended to impose restrictions on either party beyond those that are permitted by law or that conflict with Company policies.

7.Cooperation. Executive agrees to cooperate with Rogers in the truthful and honest prosecution and/or defense of any claim in which the Released Parties may have an interest (subject to reasonable limitations concerning time and place), which may include without limitation: making Executive available on a timely basis, on reasonable notice by Rogers, for interviews, meetings and other communications with auditors and outside counsel acting on behalf of Rogers in connection with any such matter; providing documents to Rogers related to any such matter; and voluntarily appearing, without a subpoena and at Rogers’s request, for a deposition or to give testimony in any hearing, trial, investigation or arbitration at the request of Rogers for any such matter. If Executive becomes legally compelled to testify or provide an interview on any matter related to Rogers, whether by subpoena or otherwise, Executive agrees to provide Rogers with prompt, written notice of such legal requirement so that Rogers may, if it so wishes, seek a

8

Exhibit 10.1

protective order or other remedy. To the extent that Rogers requests Executive’s cooperation, Rogers shall reimburse Executive for reasonable expenses consistent with Rogers’s expense reimbursement policy there in effect.

8.Return of Property. Executive agrees to return all Rogers’s property in Executive’s possession including, but not limited to, credit cards, keys, company files and internal documents (including books and manuals), and any electronic equipment (even if such electronic equipment has been available for Executive’s personal use).

9.Confidentiality. Executive and Rogers agree not to disclose the terms or conditions or the circumstances that resulted in or followed Executive’s separation from employment, to any party, excluding immediate family, except as required by law or as is reasonably necessary for purposes of securing counsel from Executive’s attorney, accountant or financial adviser. Nothing in this Section 9 is intended to impose restrictions on either party beyond those that are permitted by law, or that conflict with Company policy.

10.Consideration. The parties agree and acknowledge that there is good and sufficient consideration for the settlement of any and all issues and disputes between Executive and Rogers and for the mutual promises contained herein. Also, the parties agree and acknowledge that the terms of this Agreement are fair and equitable, reflecting both the corporate interests of Rogers and its recognition of Executive’s years of valuable service.

11.Resignation. Upon execution of this Agreement, Company will initiate the removal of Executive from any positions Executive may hold as an officer, director, signatory or agent of Rogers or any Rogers-affiliated entity, including in relation to overseas bank accounts. Executive acknowledges and agrees that Executive will, execute documents to evidence Executive’s resignation from such positions. Company shall provide reasonable evidence of such filings and will provide reasonable assistance to Executive relating to any IRS filings required as a result of the above positions during her time with the Company. Moreover, where applicable, the Company will provide reasonable assistance to Executive in Executive filing of a Form 4 required to report any non-exempt transaction in Company stock that occurs within six months of any opposite-way, non-exempt transaction that took place during Executive’s employment.

12.Entire Agreement; Continuing Obligations. Executive is voluntarily entering into this Agreement of Executive’s own free will and without influence by Rogers or any of its present or former officers, representatives, agents or employees. This Agreement constitutes the complete understanding between the parties with respect to the subject matter hereof, except that (i) during the Transition Period Executive shall remain subject to all Company policies and terms relating to her employment, and (ii) Executive acknowledges and agrees Non-Compete Agreement, which is specifically incorporated herein as terms of this Agreement, is a valid agreement supported by adequate consideration, and Executive agrees to abide in full with the terms and conditions of such agreement except as otherwise provided herein.

13.No Admission. Neither the negotiation, undertaking or execution of this Agreement shall constitute an admission by Rogers of a violation of any federal or state constitution, statute or regulation, or common law right, whether in contract or in tort.

8

Exhibit 10.1

14.Acknowledgement. Executive acknowledges and agrees that Executive is not entitled to any payments and benefits except as set forth in this Agreement and in the Offer Letter, and in particular, that this Agreement is intended to replace any benefits otherwise payable to Executive under the Rogers Severance Pay Plan for Exempt Salaried Employees.

15.Disclosure.In addition to the foregoing, and in further exchange for the consideration described in Section 2 of this Agreement, Executive specifically represents and warrants that as of the date that Executive executes this Agreement, either (i) Executive has disclosed to the Company’s General Counsel or to another member of the Company’s internal Legal Department in writing any matter that Executive knows or suspects could constitute an actual or potential violation of the Rogers Code of Ethics and Business Conduct or of any internal or external legal, regulatory or compliance requirement applicable to the Company in any jurisdiction in which it does business, or (ii) Executive has no information concerning any such matter.

16.Choice of Law. This Agreement shall be governed by and construed under the laws of the State of Connecticut, without regard to its conflicts of law rules. The parties hereby consent to the jurisdiction of the federal and state courts located in the State of Connecticut to resolve any disputes arising out of the interpretation or administration of this Agreement.

17.Severability. If any term or provision of this Agreement, or any application thereof to any circumstances, is declared invalid, in whole or in part, or otherwise unenforceable, such term or provision or application shall be deemed to have been modified to the minimum extent necessary for it to be enforceable, and shall not affect other terms or provisions or applications of this Agreement.

18.Condition. The Compensation Benefits in Section 2 are conditional upon strict compliance with Executive’s obligations and covenants under the Non-Compete Agreement and this Agreement, including but not limited to Section 7 (cooperation) and Section 8 (return of company property). Executive understands and acknowledges that a breach of any of these obligations and covenants shall result in cessation of the Compensation Benefits. All compensation payments, whether or not part of the Compensation Benefits, shall remain subject to the Rogers Corporation Compensation Recovery Policy, as amended from time to time.

19.Section 409A. This Agreement is intended to comply with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and will be interpreted in a manner intended to comply with such Section 409A and any related regulations or other pronouncements. Amounts payable under this Agreement shall be deemed not to be a “deferral of compensation” subject to Section 409A of the Code to the extent proved in the exceptions set forth in Treas. Reg. Section 1.409A-1(b)(4) (“short-term deferrals”) and Treas. Reg. Section 1.409A-1(b)(9) (“separation pay plans”) and other applicable provisions of Treas. Reg. Section 1.409A-1 through A-6. References under this Agreement to a termination of Executive’s employment shall be deemed to refer to the date upon which Executive has experienced a “separation from service” within the meaning of Section 409A of the Code. Notwithstanding anything herein to the contrary, if any payments of money or other benefits due Executive hereunder could cause the application of an accelerated or additional tax under Section 409A of the Code, such payments or other benefits shall be deferred if deferral will make such payment or other benefits compliant under Section 409A of

8

Exhibit 10.1

the Code, or otherwise such payment or other benefits shall be restructured, to the extent possible, in a manner, as reasonably determined by Rogers, that does not cause such an accelerated or additional tax. To the extent any reimbursements or in-kind benefits due to Executive hereunder constitute “deferred compensation” under Section 409A of the Code, any such reimbursements or in-kind benefits shall be paid to Executive in a manner consistent with Treas. Reg. Section 1.409A-3(i)(1)(iv). Each payment made under this Agreement shall be designated as a “separate payment” within the meaning of Section 409A of the Code.

20.Representation. Executive represents and warrants that Executive has the authority to enter into this Agreement, and that Executive has not assigned any claims being released under this Agreement to any person or entity. Executive has carefully read this Agreement and fully understands its contents and significance, and Executive acknowledges that Executive has not relied upon any representation or statement, written or oral, not set forth in this document. Executive fully understands that this Agreement constitutes a waiver of all rights available under federal and state statutes, municipal charter and common law, with regard to any matter related to Executive’s employment with Rogers, and separation therefrom with Rogers.Nothing in this Agreement and Release prohibits Executive from reporting possible violations of law to a governmental agency or entity, or requires Executive to seek authorization from the Company or to notify the Company if Executive does make such reports. This Agreement may be used as evidence in a subsequent proceeding in which any of the parties allege a breach of this Agreement.

21.Execution. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, and together, all of which shall constitute one original document. Original signatures that are transmitted by fax or electronic mail shall be considered original signatures under this Agreement.

IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the date first set forth above.

Fair Value Measurements

Fair Value Measurements

The accounting guidance for fair value measurements establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value:

• Level 1 – Quoted prices in active markets for identical assets or liabilities.

• Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

• Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

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:

Hedging Transactions and Derivative Financial Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Hedging Transactions and Derivative Financial Instruments

Hedging Transactions and Derivative Financial Instruments

We are exposed to certain risks related to our ongoing business operations. The primary risks being managed through our use of derivative instruments are foreign currency exchange rate risk and commodity pricing risk (primarily related to copper). During the first quarter of 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. 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 the constant 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. Overall, fair value is a function of five primary variables: price of the underlying instrument, time to expiration, strike price, interest rate, and volatility.

• 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, 2018, only our interest rate swap qualified for hedge accounting treatment as a cash flow hedge. For the three months endedMarch 31, 2018 and 2017, the hedge was highly effective.

Foreign Currency

During the quarter ended March 31, 2018, we entered into Korean Won, Japanese Yen, Euro, Hungarian Forint and Chinese Renminbi 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.

As of March 31, 2018 the notional values of these foreign currency forward contracts were:

Notional Values of Foreign Currency Derivatives
KRW/USD	₩	2,477,560,000
JPY/EUR	¥	310,000,000
EUR/USD	€	8,081,989
EUR/HUF	€	608,174
USD/CNY	$	10,637,837

Commodity

We currently have twenty-four outstanding contracts to hedge exposure related to the purchase of copper in our Power Electronics Solutions (PES) and Advanced Connectivity Solutions (ACS) operations. These contracts are held with financial institutions and minimize the risk associated with a potential rise in copper prices. These contracts provide some coverage over the forecasted 2018 and 2019 monthly copper exposure 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 occurs. The notional values of our copper contracts outstanding as of March 31, 2018 were:

Volume of Copper Derivatives
April 2018 - June 2018	153 metric tons per month
July 2018 - September 2018	153 metric tons per month
October 2018 - December 2018	153 metric tons per month
January 2019 - March 2019	162 metric tons per month
April 2019 - June 2019	56 metric tons per month

Interest Rates

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. This transaction has been designated as a cash flow hedge and qualifies for hedge accounting treatment. See Note 12, “Debt” for further discussion regarding the credit facility.

Stock-Based Compensation

Equity Compensation Awards

Performance-Based Restricted Stock Units

As of March 31, 2018, we had performance-based restricted stock awards from 2016, 2017 and 2018 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. Compensation expense is recognized using the straight-line method over the measurement period, unless the employee has an accelerated vesting schedule.

The 2016, 2017 and 2018 awards have one measurement criteria: the three year total shareholder return (TSR) on the performance of our capital stock as compared to that of a specified group of peer companies. The TSR measurement criteria of the awards is considered a market condition. As such, the fair value of this measurement criteria was determined on the date of grant using a Monte Carlo simulation valuation model, with related compensation expense fixed on the grant date and expensed on a straight-line basis over the life of the awards that ultimately vest and with no changes for the final projected payout of the awards.

Below were the assumptions used in the Monte Carlo calculation:

	March 31, 2018	March 31, 2017
Expected volatility	34.8%	33.6%
Expected term (in years)	3.0	3.0
Risk-free interest rate	2.28%	1.38%

Expected volatility – In determining expected volatility, we have considered a number of factors, including historical volatility.

Expected term – We use the measurement 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.

Forfeiture Rate – We account for forfeitures as they occur.

The following table summarizes the change in number of performance-based restricted stock awards outstanding for the three months ended March 31, 2018:

	Performance-Based Restricted Stock Awards
Awards outstanding at December 31, 2017	169,202
Awards granted	72,160
Stock issued	(81,230	)
Awards forfeited	(1,735	)
Awards outstanding at March 31, 2018	158,397

During the three months ended March 31, 2018, we recognized compensation expense for performance-based restricted stock awards of approximately $1.0 million. During the three months ended March 31, 2017, we recognized compensation income for performance-based restricted stock awards of approximately $0.1 million. 

Time-Based Restricted Stock Units

As of March 31, 2018, we had time-based restricted stock grants from 2014, 2015, 2016, 2017 and 2018 outstanding. The 2015, 2016, 2017 and 2018 grants all ratably vest on the first, second and third anniversaries of the original grant date. We recognize compensation expense on all of these awards on a straight-line basis over the vesting period. The Company issued 2,200 time-based restricted stock units to key employees in 2014 that cliff vest on December 17, 2018. Each restricted stock unit represents a right to receive one share of the Rogers’ capital stock at the end of the vesting period.

The fair value of the award is determined based on the market value of the underlying stock price at the grant date. We account for forfeitures as they occur.

The following table summarizes the change in number of time-based restricted stock awards outstanding for the three months ended March 31, 2018:

	Time-Based Restricted Stock Awards
Awards outstanding at December 31, 2017	173,331
Awards granted	41,100
Stock issued	(76,996	)
Awards forfeited	(1,990	)
Awards outstanding at March 31, 2018	135,445

During the three months ended March 31, 2018 we recognized compensation expense for time-based restricted stock awards of approximately $1.5 million. During the three months ended March 31, 2017 we recognized compensation expense for time-based restricted stock awards of approximately $1.0 million.

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 based on 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, 2018:

	Deferred Stock Units
Awards outstanding at December 31, 2017	9,250
Awards granted	—
Stock issued	—
Awards outstanding at March 31, 2018	9,250

During the each of the three-month periods ended March 31, 2018 and 2017, we recognized no compensation expense associated with the deferred stock units.

Stock Options

Stock options have been granted under various equity compensation plans, and they generally became exercisable in one-third increments on the second, third and fourth anniversaries of the grant dates. The maximum contractual term for all options was normally ten years. We used the Black-Scholes option-pricing model to calculate the grant-date fair value of an option. We have not granted any stock options since the first quarter of 2012.

A summary of the activity under our stock option plans during the three months ended March 31, 2018 and changes during the three months then ended, is presented below:

	Options Outstanding		Weighted- Average Exercise Price Per Share		Weighted-Average Remaining Contractual Life in Years	Aggregate Intrinsic Value
Options outstanding at December 31, 2017	33,283		$	36.40	2.2	$	4,177,655

Options vested at March 31, 2018	21,900		$	33.72	2.1	$	1,879,485

During the three months ended March 31, 2018, 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 $1.5 million, and the total amount of cash received from the exercise of these options was $0.5 million.

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 approximately $0.1 million of compensation expense associated with the plan in each of the three month periods ended March 31, 2018 and 2017.

There were no required contributions to our qualified defined benefit pension plans in the first quarter of 2018 and we are not required to make additional contributions to these plans in 2018. We paid $0.1 million of required contributions in the first quarter of 2017.

In the first quarter of 2018 and 2017, we did not make any voluntary contributions to our defined benefit pension plans.

As there is no funding requirement for the non-qualified unfunded noncontributory defined benefit pension plan or the retiree health and life insurance benefit plans, benefit payments made during the year are funded directly by the Company.

Pension Plan Proposed Termination

The Company currently intends to terminate the Rogers Plan and has requested a determination letter from the Internal Revenue Service (IRS). The termination of the Rogers Plan remains subject to final approval by both management and the IRS. The Company plans to provide for lump sum distributions or annuity payments in connection with the termination of the Rogers Plan and we expect the settlement process to be completed in late 2018 or early 2019. The Company lacks sufficient information as of March 31, 2018 to determine the financial impact of the proposed plan termination. At this time, there are no plans to terminate the Union Plan.

Segment Reporting [Abstract]

Segment Information

Segment Information

Our reporting structure is comprised of the following operating segments: ACS, EMS and PES. 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.

In January 2017, we acquired the principal operating assets of DSP, a custom manufacturer of silicone sheet, extrusions, stripping and compounds. We have integrated DSP into our EMS operating segment.

On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers. See Note 19, “Revenue from Contracts with Customers” for further information about this adoption. The Company sells products to fabricators and distributors who then sell directly into various end markets. Specifically, end markets within the ACS operating segment include wireless infrastructure, aerospace and defense, auto safety and connectivity, and consumer electronics. End markets within the EMS operating segment include general industrial, portable electronics, mass transit, and automotive. End markets within the PES operating segment include industrial, e-mobility, renewable energy, mass transit, and micro channel coolers. End markets in the Other operating segment include automotive and industrial. The following table presents a disaggregation of revenue from contracts with customers for the periods indicated; inter-segment sales have been eliminated from the net sales data:

Debt Disclosure [Abstract]

Debt

Debt

On February 17, 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).

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; or adjusted 1-month LIBOR plus 100 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.

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.

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, 2018 we have $131.0 million in outstanding borrowings under our credit facility.

At March 31, 2018, we have $2.1 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 recorded amortization expense of $0.1 million for the three months ended March 31, 2018 and 2017 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. See further discussion in 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, 2018.

Capital Leases

We have a capital lease obligation related to our manufacturing facility in Eschenbach, Germany. Under the terms of the leasing 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. The total obligation recorded for the lease as of March 31, 2018 is $5.7 million. Depreciation expense related to the capital lease was $0.1 million for each of the three-month periods ended March 31, 2018 and 2017 and these expenses are included as depreciation expense in cost of sales on our condensed consolidated statements of operations. Accumulated depreciation at March 31, 2018 and December 31, 2017 was $3.2 million and $3.3 million, respectively.

We also incurred interest expense on the capital lease of $0.1 million for each of the three month periods ended March 31, 2018 and 2017. Interest expense related to the debt recorded on the capital lease is included in interest expense on the condensed consolidated statements of operations.

In 2017, we entered into two additional capital lease agreements for office related equipment in various worldwide locations. The total obligation recorded for the capital leases as of March 31, 2018 was $0.7 million. Depreciation expense related to the capital leases was $0.1 million for the three months ended March 31, 2018. These expenses are included as depreciation expense in selling, general and administrative expenses on our condensed consolidated statements of operations. Accumulated depreciation as of March 31, 2018 was $0.2 million.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

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. We recorded an accrual of $3.2 million as of December 31, 2015 for remediation costs expected to be incurred based on the facts and circumstances known to us at that time. During the third quarter of 2016, the CT DEEP approved a change to our remediation plan for the site that will reduce our overall expected costs. Accordingly, we reduced the accrual by $0.9 million as a result of a change in the level of remediation that needs to take place. This benefit was recorded as an offset to selling, general, and administrative expenses in the condensed consolidated statement of operations. Remediation activities on the site are ongoing and are recorded as reductions to the accrual as they are incurred. We have incurred aggregate remediation costs of $0.6 million through March 31, 2018, and the remaining accrual for future remediation efforts is $1.7 million.

Superfund Sites

We are currently involved as a potentially responsible party (PRP) in one active case involving a waste disposal site, the Chatham Superfund Site. The costs incurred since inception for this claim have been immaterial and have been primarily covered by insurance policies, for both legal and remediation costs. In this matter, we have been assessed a cost sharing percentage of approximately 2% in relation to the range for estimated total cleanup costs of $18.8 million to $29.6 million. We believe we have sufficient insurance coverage to fully cover this liability and have recorded a liability and related insurance receivable of approximately $0.4 million as of March 31, 2018, which approximates our share of the low end of the estimated range. We believe we are a de minimis participant and, as such, have been allocated an insignificant percentage of the total PRP cost sharing responsibility. Based on facts presently known to us, we believe that the potential for the final results of this case having a material adverse effect on our results of operations, financial position or cash flows is remote. This case has been ongoing for many years and we believe that it will continue for the indefinite future. No time frame for completion can be estimated at the present time.

PCB Contamination

We have been working with CT DEEP and the United States Environmental Protection Agency, Region I, in connection with certain polychlorinated biphenyl (PCB) contamination at our facility in Woodstock, Connecticut. The issue was originally discovered in the soil at the facility in the late 1990s, which has been remediated. Further contamination was later found in the groundwater beneath the property, which was addressed with the installation of a pump and treat system in 2011. The future costs related to the maintenance of the groundwater pump and treat system now in place at the site are expected to be minimal. We believe that the remaining remediation activity will continue for several more years and no time frame for completion can be estimated at the present time.

PCB contamination at this facility was also found in the buildings and courtyards original to the site, in addition to surrounding areas, including an on-site pond. We have completed remediation activities for the buildings and courtyards. We currently have a reserve of $0.2 million for the pond remediation recorded in our condensed consolidated statements of financial position. We believe this reserve will be adequate to cover the remaining remediation work related to the pond contamination based on the information known at this time. However, if additional contamination is found, the cost of the remaining remediation may increase.

Asbestos Litigation

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 presents information about our recent asbestos claims activity:

	Three Months Ended March 31, 2018
Claims outstanding at December 31, 2017	687
New claims filed	65
Pending claims concluded	(78	)
Claims outstanding at March 31, 2018	674

For the three months ended March 31, 2018, 74 claims were dismissed and 4 claims were settled. Settlements totaled approximately $2.5 million for the three months ended March 31, 2018.

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. Our estimates of asbestos-related contingent liabilities and related insurance receivables are based on an independent actuarial analysis and an independent insurance usage analysis prepared annually by third parties. The actuarial analysis contains numerous assumptions, including general assumptions regarding the asbestos-related product liability litigation environment and company-specific assumptions regarding claims rates (including diseases alleged), dismissal rates, average settlement costs and average defense costs. The insurance usage analysis considers, among other things, applicable deductibles, retentions and policy limits, the solvency and historical payment experience of various insurance carriers, the likelihood of recovery as estimated by external legal counsel and existing insurance settlements.

We review our asbestos-related forecasts annually in the fourth quarter of each year unless facts and circumstances materially change during the year, at which time we would analyze these forecasts. During 2017, we reviewed the projections of our current and future asbestos claims, and determined it was appropriate to extend the liability projection period to cover all current and future claims through 2058. We based our conclusion 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 expectation of a downward trend in claims due to the average age of our claimants, which is approaching the average life expectancy. As a result, we believe we are now able to make a reasonable estimate of the actuarially determined liability for current and future asbestos claims through 2058, the expected end of our asbestos liability exposure.

As of December 31, 2017, the balances of the asbestos-related claims and insurance receivables, which are projected to cover all current and future claims through 2058, were $76.2 million and $69.2 million, respectively. 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. During the first quarter of 2018, we received notice that primary coverage for a period of eight years and excess coverage for a period of two years had been exhausted, and as a result, we incurred indemnity and defense costs of $0.3 million. These costs reduced our existing asbestos-related liabilities to $75.9 million as of March 31, 2018. 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.

We believe that it is reasonably possible that we may incur additional charges for our asbestos liabilities and defense costs in the future, which could exceed existing reserves and insurance recovery.

The amounts recorded for the asbestos-related liabilities and the related insurance receivables described above were 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.

There can be no assurance that our accrued asbestos liabilities will approximate our actual asbestos-related settlement and defense costs, or that our accrued insurance recoveries will be realized. We believe that it is reasonably possible that we may incur additional charges for our asbestos liabilities and defense costs in the future, which could exceed existing reserves and insurance recovery. We will continue to vigorously defend ourselves and believe we have substantial unutilized insurance coverage to mitigate future costs related to this matter.

General Litigation

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, after taking into account insurance coverage and the aforementioned accruals, will have a material adverse impact on our results of operations, financial position or cash flows.

Share Repurchase

Share Repurchase

On August 6, 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. As of March 31, 2018, $49.0 million remained available for repurchase under the Program.

We repurchased the following shares of capital stock during the quarter ended March 31, 2018:

(Dollars in thousands)	Three Months Ended March 31, 2018

Income Taxes

Income Taxes

Our effective income tax rate was 15.4% and 32.3% for the three months ended March 31, 2018 and 2017, respectively. The decrease was primarily due to a lower U.S. effective tax rate, as a result of U.S. tax reform, changes in pretax income mix across jurisdictions with disparate tax rates, excess tax deductions on stock based compensation, R&D credits and a release of reserves for uncertain tax positions, partially offset by an increase in current year accruals for uncertain tax positions.

The total amount of unrecognized tax benefits as of March 31, 2018 was $11.8 million, of which $10.3 million would affect our effective tax rate if recognized. It is reasonably possible that approximately $3.7 million of our unrecognized tax benefits as of March 31, 2018 will reverse within the next twelve months.

We recognize interest and penalties related to unrecognized tax benefits through income tax expense. As of March 31, 2018, we had $0.7 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 2013.

Revenue from Contracts with Customers

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, to achieve a consistent application of revenue recognition, resulting in a single revenue model to be applied by reporting companies under U.S. generally accepted accounting principles. Under the new model, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the providing entity expects to be entitled in exchange for those goods or services. In addition, the new standard requires that reporting companies disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.

We recognize revenue when all of the following criteria are met: (1) we have entered into a binding agreement, (2) the performance obligations have been identified, (3) the transaction price to the customer has been determined, (4) the transaction price has been allocated to the performance obligations in the contract, and (5) the performance obligations have been satisfied. The majority of our shipping terms permit us to recognize revenue at point of shipment. Some shipping terms require the goods to be through customs or be received by the customer before title passes. In those instances, revenue is not recognized until either the customer has received the goods or they have passed through customs, depending on the circumstances. Shipping and handling costs are treated as fulfillment costs. Sales tax or VAT are excluded from the measurement of the transaction price.

The Company manufactures some products to customer specifications which are customized to such a degree that it is unlikely that another entity would purchase these products or that we could modify these products for another customer. These products are deemed to have no alternative use to the Company whereby we have an enforceable right to payment evidenced by contractual termination clauses. In accordance with ASC 606, for those circumstances we recognize revenue on an over-time basis. Revenue recognition does not occur until the product meets the definition of “no alternative use” and therefore, items that have not yet reached that point in the production process are not included in the population of items with over-time revenue recognition.

As appropriate, we record estimated reductions to revenue for customer returns, allowances, and warranty claims. Provisions for such reductions are made at the time of sale and are typically derived from historical trends and other relevant information.

Performance Obligations

Manufactured goods are our primary performance obligations. Revenue related to our performance obligations is predominantly recognized at a point in time consistent with our shipping terms. For certain products that meet the criteria of no alternative use whereby the Company has the right to payment, we recognize revenue on an over-time basis.

The selection of a method to measure progress toward completion of a contract requires judgment and is based on the nature of the products or services to be provided. We use the cost incurred method to measure the progress of our contracts with no alternative use products whereby the Company has the right to payment as we believe it is the best depiction of the transferring of value to the customer. Under the cost incurred method, the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the contract. Contract costs include labor, materials and subcontractors costs, as well as an allocation of indirect costs. Revenues, including estimated fees or profits, are recorded as costs are incurred.

Performance obligations are typically satisfied within three months of receipt of a customer order; therefore, a change in cost estimates will not have a material impact on the percentage of completion noted at the prior quarter end. Our typical payment terms with customers range from 30 days to 105 days. Product pricing is determined and negotiated on a standalone basis. Product pricing is determined without consideration for the pricing, margin, or other information specific to other products that the same customer or other parties related to that customer may also purchase, whether in the same or a different contract. Management allocates the transaction price to its performance obligations primarily based on stand-alone selling prices that may have been developed via specific customer quote for no alternative use products and non-standard products or standard price lists for standard products. The accounting for the estimate of variable consideration is consistent with our current practice.

Contract modifications occur when there is a change to the products, price, or both. Contract modifications are treated as a separate contract if there are additions to promised goods and services that are distinct and if the price for that separate performance obligation reflects the stand-alone selling price for those goods or services. However, if the obligations in the contract modification are not distinct and are part of a single performance obligation that is only partially satisfied, the contract is not determined to be a separate contract and is accounted for as a revision to an existing contract. These modifications are accounted for prospectively when remaining promises are distinct from those previously transferred, or through a cumulative catch-up adjustment.

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, 2018.

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

	March 31, 2018
(Dollars in thousands)	Advanced Connectivity Solutions	Elastomeric Material Solutions	Power Electronics Solutions	Other	Total
Contract Assets	—	308	17,753	3,979	22,040

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

Transition

We adopted ASU 2014-09 in the first quarter of 2018 retrospectively with the cumulative effect of applying the standard recognized at the date of implementation and without restatement of comparative periods. This application of the new standard resulted in an increase to the January 1, 2018 balance of retained earnings of approximately $4.2 million, net of tax.

The guidance was applied to all contracts that were not completed at the date of implementation. The primary reason for the impact of adoption is due to over-time revenue recognition.

If the criteria for over-time recognition are not met, revenue is recognized at a point in time. In considering at what point in time control of the product or service has transferred to the customer, we consider qualitative factors such as: 1) present right to payment; 2) legal title to the asset; 3) physical possession; 4) risks and rewards of ownership; and, 5) customer acceptance.

The impact of adoption using the modified retrospective method on the Company’s condensed consolidated financial statements is as follows:

	As of
Condensed Consolidated Statements of Financial Position:	December 31, 2017					January 1, 2018
(Dollars in thousands)	Under ASC 605		Impact of Adoption			Under ASC 606

The following tables set forth the amount by which each financial statement line item is affected in the current reporting period by the application of ASC 606, as compared to the guidance that was in effect before its adoption. The impact of adoption on the condensed consolidated financial statements as of and for the three months ended March 31, 2018 is as follows:

Practical Expedients

The Company will recognize the incremental costs of obtaining a contract as an expense when incurred as the amortization period of the asset is expected to be one year or less. The Company will not adjust the promised amount of consideration for the effects of a significant financing component as we expect, at contract inception, that the period between when the transfer of goods to our customer occurs and when the customer fully pays for the goods will be one year or less. We do not disclose the Company’s unsatisfied performance obligations as they are part of contracts that have an original expected duration of one year or less.

Recent Accounting Standards

In March 2018, the Financial Accounting Standards Board (FASB) issued ASU No. 2018-05, Income Taxes (Topic 740):Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. This ASU adds guidance that answers questions regarding how certain income tax effects from the Tax Cuts and Jobs Act (the Act) should be applied to companies’ financial statements. The guidance also lists which financial statement disclosures are required under a measurement period approach.

In February 2018, the FASB issued ASU No. 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 the Act from accumulated other comprehensive income to retained earnings. This ASU is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the method and impact the adoption of ASU 2018-02 will have on the Company’s consolidated financial statements and disclosures.

In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income (GILTI) provisions of the Act. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or to treat any taxes on GILTI inclusions as period costs are both acceptable methods subject to an accounting policy election. Effective in the first quarter of 2018, the Company has elected to treat any potential GILTI inclusions as a period cost.

In December 2017, Staff Accounting Bulletin No. 118 (SAB 118) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, we recorded provisional estimates for the deferred tax expense recorded in connection with the remeasurement of certain deferred tax assets and tax expense associated with the mandatory deemed repatriation of foreign earnings at December 31, 2017. Management has continued to gather and analyze information associated with these provisional estimates and did not record any adjustments during the three months ended March 31, 2018. Any subsequent adjustment to these amounts will be recorded to tax expense in the quarter of 2018 when the analysis is complete.

In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. ASU No. 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017. Adoption of this standard will be applied prospectively to awards modified on or after the adoption date. The impact of this new standard will depend on the extent and nature of future changes to the terms and conditions of the Company’s share-based payment awards. The Company adopted this standard on January 1, 2018, which did not have a material effect on the condensed consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost. The changes to the standard require employers to report the service cost component in the same line item as other compensation costs arising from services rendered by employees during the reporting period. The other components of net periodic pension benefit costs will be presented in the statement of operations separately from the service cost and outside of a subtotal of operating income from operations. In addition, only the service cost component may be eligible for capitalization where applicable. ASU 2017-07 is effective for annual periods beginning after December 15, 2017. The Company adopted this standard on January 1, 2018. In conjunction with the adoption of this guidance, the Company reclassified $0.4 million in net periodic pension benefits from Selling, general and administrative expenses to Other income (expense), net for the three months ended March 31, 2017.

In February 2016, the FASB issued ASU No. 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 No. 2016-02 supersedes the existing guidance on accounting for leases. The standard is effective for interim and annual reporting periods for fiscal years beginning after December 15, 2018. Early adoption of this standard is permitted and it is to be adopted using a modified retrospective approach. The Company has established an inventory of existing leases and is in the process of evaluating the classification of each lease and quantifying the accounting impact in accordance with the new standard. The Company expects to adopt this accounting standard beginning in fiscal year 2019.

Facility Consolidation

On April 24, 2018, we made the decision to relocate our Santa Fe Springs, California operations to the Company’s facilities in Carol Stream, Illinois and Bear, Delaware. We expect to incur restructuring expenses of approximately $2.0 million in connection with the closure and transfer of production capabilities to the Carol Stream facility. These costs include approximately $0.8 million in severance and retention expenses and $1.2 million of costs related to the relocation of equipment. The Company estimates that approximately $1.5 million and $0.5 million of the costs will be incurred in fiscal years 2018 and 2019, respectively.Completion of the transfer, and start-up of production at other Company facilities, is expected to require capital expenditures of approximately $1.2 million to $1.4 million.

Sale of Property

In February 2018, we signed an agreement for the sale of a building and one parcel of land for an aggregate sales price of $1.1 million. The assets were classified as held for sale with an aggregate net book value of approximately $0.5 million as of March 31, 2018. The sale transaction closed in April 2018.
