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 U.S. generally accepted accounting principles for interim financial information. Accordingly, these statements do not include all of the information and footnotes required by U.S. generally accepted accounting principles ("GAAP") for complete financial statements. In our opinion, the accompanying condensed consolidated financial statements include all normal recurring adjustments necessary for their fair presentation in accordance with GAAP. All significant intercompany transactions have been eliminated.

Interim results are not necessarily indicative of results for a full year. For further information regarding our accounting policies, refer to the audited consolidated financial statements and footnotes thereto included in our Form 10-K for the fiscal year ended December 31, 2014.

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 option contracts, interest rate swaps and copper derivative contracts. Assets and liabilities measured on a recurring basis, categorized by the level of inputs used in the valuation, include:

(Dollars in thousands)	Carrying amount as of June 30, 2015			Level 1	Level 2			Level 3

Derivatives Contracts

We are exposed to certain risks related to our ongoing business operations. The primary risks being managed through the use of derivative instruments are foreign currency exchange rate risk, commodity pricing risk (primarily related to copper) and interest rate risk.   

• 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.

We do not use derivative financial instruments for trading or speculative purposes.

For further discussion on our derivative contracts, see Note 3 - "Hedging Transactions and Derivative Financial Instruments" below.

Note 3 – Hedging Transactions and Derivative Financial Instruments

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 special hedge accounting treatment as defined under the applicable accounting guidance. For derivative instruments that are designated and qualify for hedge accounting treatment (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 income associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of the future cash flows of the hedged item (i.e., the ineffective portion) if any, is recognized in the statements of income during the current period. For the six month periods ended June 30, 2015 and 2014, there was no hedge ineffectiveness.

We currently have twenty-three outstanding contracts to hedge exposure related to the purchase of copper in our Power Electronics Solutions and Advanced Connectivity Solutions 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 2015 and 2016 monthly copper exposure and do not qualify for hedge accounting treatment; therefore, any mark-to-market adjustments required on these contracts are recorded in the other income (expense), net line item in our condensed consolidated statements of income. 

During the six months ended June 30, 2015, we entered into Euro, Japanese Yen, Hungarian Forint, Korean Yuan and Chinese Yuan currency forward contracts. We entered into these foreign currency forward contracts to mitigate certain global balance sheet exposures. Certain contracts qualify for hedge accounting treatment, while others do not. Mark-to-market adjustments are recorded in the other income (expense), net line item in our condensed consolidated statements of income for those contracts that do not qualify for hedge accounting treatment. For those contracts that do qualify for hedge accounting treatment mark-to-market adjustments are recorded in other comprehensive income.

In July 2012, we entered into an interest rate swap to hedge the variable interest rate on our term loan debt. As of June 30, 2015, the remaining notional amount of the interest rate swap covers $32.5 million of our term loan debt. This transaction has been designated as a cash flow hedge and qualifies for hedge accounting treatment. At June 30, 2015, our term loan debt of $55.0 million and revolving line of credit borrowings of $125.0 million represent our total outstanding debt. At June 30, 2015, the rate charged on this debt was the 1 month London interbank offered rate ("LIBOR") at 0.1875% plus a spread of 1.625%.

Concentration of Credit Risk

By using derivative instruments, we are subject to credit and market risk. If a counterparty fails to fulfill its performance obligations under a derivative contract, our credit risk will equal the fair value of the derivative instrument. Generally, when the fair value of a derivative contract is positive, the counterparty owes the Company, thus creating a receivable risk for the Company. We minimize counterparty credit (or repayment) risk by entering into derivative transactions with major financial institutions with investment grade credit ratings.

Note 4 - Inventories

Inventories were as follows:

Raw materials	$	32,765	$	26,787
Work-in-process	22,572		16,564
Finished goods	31,695		25,277
Total Inventory	$	87,032	$	68,628

Note 5 - Acquisition

On January 22, 2015, we completed the previously announced acquisition of Arlon and its subsidiaries, other than Arlon India (Pvt) Limited (collectively, “Arlon”), pursuant to the terms of the Stock Purchase Agreement, dated December 18, 2014, by and among the Company, Handy & Harman Group, Ltd. (“H&H Group”) and its subsidiary Bairnco Corporation (“Bairnco”) (as amended, the “Purchase Agreement”).

Pursuant to the terms of the Purchase Agreement, we acquired Arlon and assumed certain liabilities related to the acquisition for an aggregate purchase price of approximately $157 million. The purchase price is subject to final post-closing adjustments under the terms of the Purchase Agreement.

We used borrowings of $125.0 million under our bank credit facility in addition to cash on hand, to fund the acquisition.

Arlon manufactures high performance materials for the printed circuit board industry and silicone rubber-based materials. The acquisition of Arlon and its integration into our operating segments is expected to provide increased scale and complementary product offerings, allowing us to enhance our ability to support our customers.

11

The acquisition has been accounted for in accordance with applicable purchase accounting guidance. The following table represents the preliminary fair market values assigned to the acquired assets and liabilities in the transaction. On a preliminary basis, we recorded goodwill, primarily related to the expected synergies from combining operations and the value of the existing workforce. We also recorded intangible assets related to trademarks, technology and customer relationships. As of the filing date of this Form 10-Q, the process of valuing the net assets of the business is substantially complete. These values may be updated until certain items are settled in the final agreement.

(Dollars in thousands)
	January 22, 2015
Assets:
Cash	$	142
Accounts receivable	17,301
Other current assets	856
Inventory	9,916
Deferred income tax assets, current	1,278
Property, plant & equipment	30,667
Intangible assets	50,020
Goodwill	86,337
Total assets	196,517
Liabilities:
Accounts payable	4,958
Other current liabilities	4,249
Deferred tax liability	23,706
Other long-term liabilities	5,056
Total liabilities	37,969
Fair value of net assets acquired	$	158,548

The intangible assets consist of developed technology valued at $15.8 million, customer relationships valued at $32.7 million and trademarks valued at $1.6 million. The fair value of acquired identified intangible assets was determined by applying the income approach, using several significant unobservable inputs for projected cash flows and a discount rate. These inputs are considered Level 3 under the fair value measurements and disclosure guidance.

The weighted average amortization period for the intangible asset classes are 5.7 years for developed technology, 6.0 years for customer relationships and 3.2 years for trademarks, resulting in amortization expenses ranging from $1.8 million to $5.8 million annually. The estimated annual future amortization expense is $3.2 million for the remainder of 2015, and $5.8 million for each of the years ending 2016, 2017, 2018 and 2019.

During the first six months of 2015, we incurred transaction costs of $1.5 million, which were recorded within selling and administrative expenses on the condensed consolidated statement of income.

The results of Arlon have been included in our consolidated financial statements only for the period subsequent to the completion of our acquisition on January 22, 2015. Arlon's revenues for the three and six month periods ended June 30, 2015 totaled $25.4 million and $45.6 million, respectively.

Note 8 – Stock-Based Compensation

Equity Compensation Awards

Stock Options

Stock options have been granted under various equity compensation plans. While we may grant options to employees that become exercisable at different times or within different periods, we have generally granted options to employees that vest and become exercisable in one-third increments on the second, third and fourth anniversaries of the grant dates. The maximum contractual term for all options is normally ten years.

We use 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.

In most cases, we recognize expense using the straight-line method for stock option grants. The amount of stock-based compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option. We currently expect, based on an analysis of our historical forfeitures, an annual forfeiture rate of approximately 3% and applied that rate to the grants issued. This assumption is reviewed periodically and the rate is adjusted as necessary based on these reviews. Ultimately, the actual expense recognized over the vesting period will only be for those options that vest.

During the three and six month periods ended June 30, 2015 we recognized approximately $0.1 million and $0.1 million of stock option compensation expense, respectively. During the three and six month periods ended June 30, 2014 we recognized approximately $0.1 million and $0.2 million of stock option compensation expense, respectively.

15

A summary of the activity under our stock option plans as of June 30, 2015 and changes during the three and six month periods 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 March 31, 2015	251,400		$	41.06	3.7	$	10,344,139
Options exercised	(26,562	)	$	46.09
Options forfeited	(600	)	$	34.83
Options outstanding at June 30, 2015	224,238		$	40.49	3.5	5,752,806
Options exercisable at June 30, 2015	223,427		$	39.98	3.2	5,845,097
Options vested or expected to vest at June 30, 2015*	224,214		$	40.47	3.5	5,755,574

* In addition to the vested options, we expect a portion of the unvested options to vest at some point in the future. Options expected to vest are calculated by applying an estimated forfeiture rate to the unvested options.

	Options Outstanding		Weighted- Average Exercise Price Per Share
Options outstanding at December 31, 2014	393,347		$	40.72
Options exercised	(167,659	)	$	40.91
Options forfeited	(1,450	)	$	39.62
Options outstanding at June 30, 2015	224,238

During the six month period ended June 30, 2015, 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 $6.4 million, and the total amount of cash received from the exercise of these options was $6.2 million.

Performance-Based Restricted Stock

In 2006, we began granting performance-based restricted stock awards. We currently have awards from 2013, 2014 and 2015 outstanding. These awards cliff vest at the end of the three year measurement period, except for the 2015 grants to those individuals who are retirement eligible during the grant period. These individuals may receive a pro-rata payout based on the actual retirement date if it occurs during the vesting period. Participants are eligible to be awarded shares ranging from 0% to 200% of the original award amount, based on certain defined measurement criteria. Compensation expense is recognized using the straight-line method over the vesting period.  

All outstanding awards have two measurement criteria on which the final payout of each award is based - (i) the three year return on invested capital (ROIC) compared to that of a specified group of peer companies, and (ii) the three year total shareholder return (TSR) on the performance of our common stock as compared to that of a specified group of peer companies. In accordance with the applicable accounting literature, the ROIC portion of each award is considered a performance condition. As such, the fair value of each award is determined based on the market value of the underlying stock price at the grant date with cumulative compensation expense recognized to date being increased or decreased based on changes in the forecasted pay out percentage at the end of each reporting period. The TSR portion of the award is considered a market condition. As such, the fair value of this award 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 with no changes for the final projected payout of the award.

The amount of performance-based restricted stock compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” and represents only the unvested portion of the surrendered award. We currently expect, based on an analysis of our historical forfeitures, an annual forfeiture rate of approximately 7% and applied that rate to the grants issued. This assumption will be reviewed periodically and the rate will be adjusted as necessary based on these reviews. Ultimately, the actual expense recognized over the vesting period will only be for those awards that vest.

Below are the assumptions used in the Monte Carlo calculation:

	June 30, 2015	June 30, 2014
Expected volatility	28.2%	33.7%
Expected term (in years)	3.0	3.0
Risk-free interest rate	0.96%	0.67%
Expected dividend yield	—	—

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

Expected term – We use the vesting period of the award to determine the expected term assumption for the Monte Carlo simulation valuation model.

Risk-free interest rate – We use an implied "spot rate" yield on U.S. Treasury Constant Maturity rates as of the grant date for our assumption of the risk-free interest rate.

Expected dividend yield – We do not currently pay dividends on our common stock; therefore, a dividend yield of 0% was used in the Monte Carlo simulation valuation model.

Actual performance during the relevant period for the 2012 award, which vested as of December 31, 2014, met the target performance criteria and shares were paid out at 120.0% of target during the second quarter of 2015.

	Performance-Based Restricted Stock Awards
Non-vested awards outstanding at December 31, 2014	92,437
Awards granted	50,798
Stock issued	(20,910	)
Awards forfeited	(8,605	)
Non-vested awards outstanding at June 30, 2015	113,720

During the three and six months periods ended June 30, 2015, we recognized compensation expense for performance-based restricted stock awards of approximately $1.2 million and $1.6 million, respectively. During the three and six month periods ended June 30, 2014, we recognized expense for performance-based restricted stock awards of approximately $0.7 million and $1.3 million, respectively.

Time-Based Restricted Stock

In 2011, we began granting time-based restricted stock awards to certain key executives and other key members of the Company’s management team. We currently have grants from 2011, 2012, 2013, 2014 and 2015 outstanding. The 2011 and 2012 grants cliff vest at the end of the four and three year vesting periods, respectively. The 2013, 2014 and 2015 grants typically vest on the first, second and third anniversaries of the original grant date. We do occasionally grant awards that cliff vest after 4 years. We recognize compensation expense on all of these awards on a straight-line basis over 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.

The amount of time-based restricted stock compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” and represents only the unvested portion of the surrendered award. We currently expect, based on an analysis of our historical forfeitures, an annual forfeiture rate of approximately 7% and applied that rate to the grants issued. This assumption will be reviewed periodically and the rate will be adjusted as necessary based on these reviews. Ultimately, the actual expense recognized over the vesting period will only be for those awards that vest.

	Time-Based Restricted Stock Awards
Non-vested awards outstanding at December 31, 2014	238,386
Awards granted	65,285
Stock issued	(69,352	)
Awards forfeited	(4,969	)
Non-vested awards outstanding at June 30, 2015	229,350

During the three and six month periods ended June 30, 2015, we recognized compensation expense for time-based restricted stock awards of approximately $1.3 million and $2.4 million, respectively. During the three and six month periods ended June 30, 2014, we recognized compensation expense for time-based restricted stock awards of approximately $1.1 million and $2.1 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’ 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.

	Deferred Stock Units
Awards outstanding at December 31, 2014	30,150
Awards granted	9,100
Stock issued	(15,400	)
Awards outstanding at June 30, 2015	23,850

For both the three and six month periods ended June 30, 2015 and 2014 we recognized compensation expense for deferred stock units of $0.7 million and $0.8 million, respectively.

Employee Stock Purchase Plan

We have an employee stock purchase plan (ESPP) that allows eligible employees to purchase, through payroll deductions, shares of our common 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 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 amount 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 for each of the three month periods ended June 30, 2015 and 2014, and approximately $0.2 million of compensation expense associated with each of the six month periods ended June 30, 2015 and 2014.

In the first quarter of 2015, as part of the acquisition of Arlon, we acquired the Hourly Employees Pension Plan of Arlon, LLC, Microwave Materials and Silicone Technologies Divisions, Bear, Delaware. This plan covers Arlon union employees and was frozen to new participants and accumulating benefits in 2006. As of the acquisition date, January 22, 2015, the funded status of the plan was a liability of approximately $2.0 million. We have recorded this as part of our long term pension liability within our condensed consolidated statements of financial position.

In the first quarter of 2014, we made a one-time cash payment to a former employee of $0.8 million in accordance with the provisions of his retirement contract related to his participation in the Company's Pension Restoration Plan. This payment resulted in a settlement charge of approximately $0.1 million, which was recognized in the first quarter of 2014.

Employer Contributions

In the second quarters of 2015 and 2014, we made voluntary contributions of $6.5 million and $6.5 million, respectively to our qualified defined benefit pension plans. These are the only amounts contributed in the first six months of 2015 and 2014.

We did not make any contributions to our non-qualified defined benefit pension plan for the six months ended June 30, 2015 or the three months ended June 30, 2014. We made $0.8 million in contributions to our non-qualified defined benefit pension plan for the quarter ended March 31, 2014.

Note 10 – Segment Information

Our reporting structure is comprised of the following operating segments: Advanced Connectivity Solutions (ACS), Elastomeric Material Solutions (EMS), Power Electronics Solutions (PES) and the Other segment. We believe this structure aligns our external reporting presentation with how we currently manage and view our business internally. In the second quarter of 2015, we concluded that we needed to update two of our operating segment names to better align the business product portfolio offerings to the market. Therefore, Advanced Connectivity Solutions replaces the name of Printed Circuit Materials, and Elastomeric Material Solutions replaces the name of High Performance Foams. There were no changes to the composition of these two operating segments. The Power Electronics Solutions and Other segment names remain unchanged.

We completed the acquisition of Arlon on January 22, 2015. As part of the integration process, Arlon operations related to circuit materials and silicones were included in our ACS and EMS segments, respectively. The Other segment includes the Arlon business that manufactures specialty polyimide, epoxy-based laminates and bonding materials.

As a result of the acquisition, we significantly increased our asset holdings. The following table sets forth the total assets allocated to each segment:

(Dollars in thousands)
	June 30, 2015

Note 11 – Joint Ventures

As of June 30, 2015, we had two joint ventures, each 50% owned, which were accounted for under the equity method of accounting.

Joint Venture	Location	Reportable 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

20

We recognized equity income related to the joint ventures of $0.4 million and $1.3 million for the three and six month periods ended June 30, 2015, respectively. We recognized equity income related to the joint ventures of $1.1 million and $2.0 million for the three and six month periods ended June 30, 2014, respectively. These amounts are included in the condensed consolidated statements of income.

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

(Dollars in thousands)	Three Months Ended				Six Months Ended
	June 30, 2015		June 30, 2014		June 30, 2015		June 30, 2014
Net sales	$	9,708	$	12,751	$	20,613	$	24,160
Gross profit	1,865		3,921		4,927		7,214
Net income	784		2,124		2,622		4,078

Receivables from and payables to joint ventures arise during the normal course of business from transactions between us and the joint ventures, typically from the joint venture purchasing raw materials from us to produce end products, which are sold to third parties, or from us purchasing finished goods from our joint ventures, which are then sold to third parties.

Note 12 - Debt

On June 18, 2015, we entered into a secured five year credit agreement (the "Amended Credit Agreement"). The Amended Credit Agreement amends and restates the credit agreement signed between the Company and the same banks on July 13, 2011 and increased our borrowing capacity from $265.0 million to $350.0 million, with an additional $50.0 million expansion option.

The Amended Credit Agreement provides (1) a $55.0 million term loan; (2) up to $295.0 million of revolving loans, with sub-limits for multicurrency borrowings, letters of credit and swing-line notes; and (3) a $50.0 million expansion 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 Amended Credit Agreement).  

Borrowings under the Amended Credit Agreement bear interest based on one of two options. 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 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 Amended Credit Agreement, the Company is required to pay a quarterly fee of 0.20% to 0.30% (based upon our leverage ratio) of the unused amount of the lenders’ commitments under the Amended Credit Agreement.

The Amended Credit Agreement contains customary representations, warranties, covenants, mandatory prepayments and events of default under which the Company's payment obligations may be accelerated. The financial covenants include requirements to maintain (1) a leverage ratio of no more than 3.25 to 1.00, subject to a one-time 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 ("ICR") of no less than 3.00 to 1.00. The ICR is the ratio determined as of the end of each of its fiscal quarters ending on and after June 30, 2015, of (i) Consolidated Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) (as defined in the Amended Credit Agreement) minus the unfinanced portion of Consolidated Capital Expenditures to (ii) Consolidated Interest Expense paid in cash, in each case for the period of four consecutive fiscal quarters ending with the end of such fiscal quarter, all calculated for the Borrower and its subsidiaries on a consolidated basis.

As of June 30, 2015, we were in compliance with all of the financial covenants in the Amended Credit Agreement, as we achieved actual ratios of approximately 1.34 to 1.00 on the leverage ratio and 30.68 to 1.00 on the ICR.

21

The Amended Credit Agreement requires the mandatory quarterly repayment of principal on amounts borrowed under such term loan. Payments will commence on September 30, 2015, and are scheduled to be completed on June 30, 2020. The aggregate mandatory principal payments due are as follows:

2015	$1.4	million
2016	$3.4	million
2017	$4.1	million
2018	$4.8	million
2019	$5.5	million
2020	$160.8	million

All obligations under the Amended Credit Agreement are guaranteed by each of the Corporation’s existing and future material domestic subsidiaries, as defined in the Amended Credit Agreement (the “Guarantors”). The obligations are also secured by a Second Amended and Restated Pledge and Security Agreement, dated as of June 18, 2015, entered into by the Company 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 Company and the Guarantors.

All amounts borrowed or outstanding under the Amended Credit Agreement, with the exception of amounts borrowed under the term loan which are subject to quarterly principal payments, are due and mature on June 18, 2020, unless the commitments are terminated earlier either at the request of the Company or if certain events of default occur. At June 30, 2015, the Company had outstanding debt of $180.0 million under the Amended Credit Agreement which included $55.0 million borrowed under the term loan and $125.0 million borrowed under the revolving line of credit.

In addition, as of June 30, 2015 we had a $1.4 million standby letter of credit (LOC) to guarantee Rogers workers compensation plans that were backed by the Amended Credit Agreement. No amounts were drawn on the LOC as of June 30, 2015 or December 31, 2014.

The Amended Credit Agreement is secured by many of the assets of Rogers, including but not limited to, receivables, equipment, intellectual property, inventory, and stock in certain subsidiaries.

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.  

Before entering into the Amended Credit Agreement, we had $0.5 million of remaining capitalized costs from the previous credit agreements. These costs will continue to be amortized over the life of the Amended Credit Agreement. In the second quarter of 2015, we capitalized an additional $1.6 million in connection with the Amended Credit Agreement. These costs will be amortized over the life of the Amended Credit Agreement, which will terminate in June 2020. 

We incurred amortization expense of $0.1 million in each of the second quarters of 2015 and 2014, and amortization expense of $0.2 million in each of the first six months of 2015 and 2014. At June 30, 2015, we have approximately $2.1 million of credit facility costs remaining to be amortized.

We borrowed $125.0 million under the line of credit in the first quarter of 2015 to fund the acquisition of Arlon. During the first six months of 2015 and 2014, we made principal payments of $5.0 million and $7.5 million, respectively, on the outstanding debt. The principal amount of this debt has been transferred to the new revolving credit line created in June of 2015. We are obligated to pay $2.8 million on this debt obligation in the next 12 months under the term loan.

We incurred interest expense on our outstanding debt of $1.1 million and $1.9 million for the three and six month periods ended June 30, 2015, respectively, and $0.5 million and $1.0 million for the three and six month periods ended June 30, 2014, respectively.

We incurred an unused commitment fee of $0.1 million and $0.1 million for the three and six month periods ended June 30, 2015 and $0.1 million and $0.2 million for the three and six month periods ended June 30, 2014, respectively. In July 2012, we entered into an interest rate swap to hedge the variable interest rate on our term loan debt. As of June 30, 2015, the remaining notional amount of the interest rate swap covers $32.5 million of our term loan debt. At June 30, 2015, our outstanding debt balance is comprised of a term loan of $55.0 million and $125.0 million borrowed on the revolving line of credit. At June 30, 2015, the rate charged on this debt is the 1 month LIBOR at 0.1875% plus a spread of 1.625%.

Pursuant to the Amended Credit Agreement, we cannot make a cash dividend payment if (i) a default or event of default has occurred and is continuing or will result from the cash dividend payment or (ii) if the aggregate amount of all cash dividend payments and other such restricted payments (as defined in the Amended Credit Agreement) that are otherwise not permitted during any fiscal year exceeds $10.0 million; provided that, if at the time of and immediately after giving effect (including on a

22

pro forma basis) thereto, the Leverage Ratio (as defined in the Amended Credit Agreement) is less than or equal to 2.00 to 1.00, such dollar limitation would not apply.

Capital Lease

During the first quarter of 2011, we recorded a capital lease obligation related to the acquisition of Curamik Electronics GmbH ("Curamik") for its primary 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 June 30, 2015 is $6.1 million. Depreciation expense related to the capital lease was $0.1 million in each of the three month periods ended June 30, 2015 and 2014 and $0.2 million in the six month periods ending June 30, 2015 and 2014. Accumulated depreciation at June 30, 2015 and December 31, 2014 was $1.8 million and $1.6 million, respectively. These expenses are included as depreciation expense in cost of sales on our condensed consolidated statements of income.

We also incurred interest expense on the capital lease of $0.1 million and $0.2 million for the three and six month periods ended June 30, 2015, respectively, and $0.1 million and $0.3 million for the three and six month periods ended June 30, 2014, respectively. Interest expense related to the debt recorded on the capital lease is included in interest expense on the condensed consolidated statements of income.

We guarantee an interest rate swap related to our lease of the manufacturing facility in Eschenbach, Germany. The swap is in a liability position with the bank at June 30, 2015, and has a fair value of $0.3 million. We have concluded that default by the lessor is not probable during the term of the swap, and we have chosen not to exercise the option to buyout the lease during the leasing period; therefore, the guarantee has no value. For more information about the manufacturing facility, see Capital Lease section below.

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

On January 22, 2015, we acquired Arlon. For further detail on the goodwill and intangible assets recorded on the acquisition, see Note 5 - "Acquisition".

Amortization expense for the three and six month periods ended June 30, 2015 was approximately $2.8 million and $5.2 million, respectively. Amortization expense was $1.6 million and $3.1 million for the three and six month periods ended June 30, 2014, respectively. The estimated annual future amortization expense is $5.7 million, $10.4 million, $10.0 million, $9.5 million and $9.0 million for the remainder of 2015, 2016, 2017, 2018 and 2019, respectively.

Approximately $5.3 million of indefinite-lived trademark intangible assets were acquired from the acquisitions of Curamik. These assets are assessed for impairment annually or when changes in circumstances indicated that the carrying values may be recoverable. The definite-lived intangibles are amortized using a fair value methodology that is based on the projected economic use of the related underlying asset.

Note 14 – Commitments and Contingencies

We are currently engaged in the following environmental and legal proceedings:

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 June 30, 2015, 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 on for the indefinite future. No time frame for completion can be estimated at the present time.

PCB Contamination

We have been working with the Connecticut Department of Energy and Environmental Protection (CT DEEP) and the United States Environmental Protection Agency (EPA), 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, and this initial issue was remediated in 2000. 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. Additional PCB contamination at this facility was found in the original buildings, courtyards and surrounding areas including an on-site pond. Remediation activities of the affected building materials and courtyards were completed in 2014 at a total cost of $0.5 million. Remediation costs related to the soil contamination and the on-site pond are ongoing and expected to approximate $0.7 million. The soil contamination remediation is completed and we currently have a reserve of $0.2 million for the pond remediation recorded in our consolidated statements of financial position. We believe this reserve will be adequate to cover the remaining remediation work related to the soil and pond contamination based on the information known at this time. However, if additional contamination is found, the cost of the remaining remediation may increase.

Overall, we have spent approximately $2.4 million in remediation and monitoring costs related to these various PCB contamination issues. 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.

Asbestos Litigation

A significant number of asbestos-related product liability claims have been brought against numerous United States industrial companies where the third-party plaintiffs allege personal injury from exposure to asbestos-containing products. We have been named, along with hundreds of other companies, as a defendant in some of these claims. In virtually all of these claims filed against us, the plaintiffs are seeking unspecified damages, or, if an amount is specified, such amount merely represents a jurisdictional

24

amount. However, occasionally specific damages are alleged and in such situations, plaintiffs’ lawyers often sue dozens of defendants, frequently without factual basis or support. As a result, even when a specific amount of damages is alleged, such action can be arbitrary, both as to the amount being sought and the defendant being charged with such damages.

We did not mine, mill, manufacture or market asbestos; rather we made a limited number of products which contained encapsulated asbestos. Such products were provided to industrial users. We stopped manufacturing these products in the late 1980s.

• Claims

We have been named in asbestos litigation primarily in Illinois, Pennsylvania and Mississippi. As of June 30, 2015, there were 444 pending claims compared to 438 pending claims at December 31, 2014. The number of pending claims at a particular time can fluctuate significantly from period to period depending on how successful we have been in getting these cases dismissed or settled. Some jurisdictions prohibit specifying alleged damages in personal injury tort cases such as these, other than a minimum jurisdictional amount which may be required for such reasons as allowing the case to be litigated in a jury trial (which the plaintiffs believe will be more favorable to them than if heard only before a judge) or allowing the case to be litigated in federal court. This is in contrast to commercial litigation, in which specific alleged damage claims are often permitted. The prohibition on specifying alleged damages sometimes applies not only to the suit when filed but also during the trial – in some jurisdictions the plaintiff is not actually permitted to specify to the jury during the course of the trial the amount of alleged damages the plaintiff is claiming. Further, in those jurisdictions in which plaintiffs are permitted to claim specific alleged damages, many plaintiffs nonetheless still choose not to do so. In those cases in which plaintiffs are permitted to and choose to assert specific dollar amounts in their complaints, we believe the amounts claimed are typically not meaningful as an indicator of a company’s potential liability. This is because (1) the amounts claimed may bear no relation to the level of the plaintiff’s alleged injury and are often used as part of the plaintiff’s litigation strategy, (2) the complaints typically assert claims against numerous defendants, and often the alleged damages are not allocated against specific defendants, but rather the broad claim is made against all of the defendants as a group, making it impossible for a particular defendant to quantify the alleged damages that are being specifically claimed against it and therefore its potential liability, and (3) many cases are brought on behalf of plaintiffs who have not suffered any medical injury, and ultimately are resolved without any payment or payment of a small fraction of the damages initially claimed.

We believe the rate at which plaintiffs filed asbestos-related suits against us increased in 2001, 2002, 2003 and 2004 because of increased activity on the part of plaintiffs to identify those companies that sold asbestos-containing products, but which did not directly mine, mill or market asbestos. A significant increase in the volume of asbestos-related bodily injury cases arose in Mississippi in 2002. This increase in the volume of claims in Mississippi was apparently due to the passage of tort reform legislation (applicable to asbestos-related injuries), which became effective on September 1, 2003 and which resulted in a higher than average number of claims being filed in Mississippi by plaintiffs seeking to ensure their claims would be governed by the law in effect prior to the passage of tort reform. The number of asbestos related suits filed against us decreased slightly in 2005 and 2006, but increased slightly in 2007, declined in 2008 and increased again in 2009 and 2010. The number of lawsuits filed against us in 2011, 2012, 2013, 2014 and the first six months of 2015 (annualized) was significantly higher than in 2010. These new lawsuits are reflected in the National Economic Research Associates, Inc. ("NERA") and Marsh USA, Inc. ("Marsh") reports. See "Impact on Financials Statements" section below.

• Defenses

In many cases, plaintiffs are unable to demonstrate that they have suffered any compensable loss as a result of exposure to our asbestos-containing products. We believe that the trend will continue and that a majority of the claimants in pending cases will not be able to demonstrate exposure or loss. This belief is based in large part on the limited number of asbestos-related products manufactured and sold by us and the fact that the asbestos was encapsulated in such products. In addition, even at sites where the presence of an alleged injured party can be verified during the same period those products were used, our liability cannot be presumed because even if an individual contracted an asbestos-related disease, not everyone who was employed at a site was exposed to the asbestos containing products that we manufactured. Based on these and other factors, we have and will continue to vigorously defend ourselves in asbestos-related matters.

• Dismissals and Settlements

Cases involving us typically name 50-300 defendants, although some cases have had as few as one (1) and as many as 833 defendants. We have obtained the dismissal of many of these claims. For the six months ended June 30, 2015, 45 claims were dismissed and one claim was settled. For the year ended December 31, 2014, 104 claims were dismissed and 13 were settled. The majority of costs have been paid by our insurance carriers, including the costs associated with the small number of cases that have been settled. We paid $0.5 million on settlements for the six months ended June 30, 2015, compared to $3.2 million for the year ended 2014. Although these figures provide some insight into our experience with asbestos litigation, no guarantee can be made as to the dismissal and settlement rates that we will experience in the future.

25

Settlements are made without any admission of liability. Settlement amounts may vary depending upon a number of factors, including the jurisdiction where the action was brought, the nature and extent of the disease alleged and the associated medical evidence, the age and occupation of the claimant, the existence or absence of other possible causes of the alleged illness of the alleged injured party and the availability of legal defenses, as well as whether the action is brought alone or as part of a group of claimants. To date, we have been successful in obtaining dismissals for many of the claims and have settled only a limited number. Most of the settled claims were settled for nominal amounts, and the majority of such payments have been borne by our insurance carriers. In addition, to date, we have not been required to pay any punitive damage awards.

• Potential Liability

NERA has historically been engaged to assist us in projecting our future asbestos-related liabilities and defense costs with regard to pending claims and future claims. Projecting future asbestos costs is subject to numerous variables that are extremely difficult to predict, including the number of claims that might be received, the type and severity of the disease alleged by each claimant, the long latency period associated with asbestos exposure, dismissal rates, costs of medical treatment, the financial resources of other companies that are co-defendants in claims, uncertainties surrounding the litigation process from jurisdiction to jurisdiction and from case to case and the impact of potential changes in legislative or judicial standards, including potential tort reform. Furthermore, any predictions with respect to these variables are subject to even greater uncertainty as the projection period lengthens. In light of these inherent uncertainties, the  variability of our claims history and consultations with NERA, we currently believe that ten years is the most reasonable period for recognizing a reserve for future costs, and that costs that might be incurred after that period are not reasonably estimable at this time. As a result, we also believe that our ultimate asbestos-related contingent liability (i.e., our indemnity or other claim disposition costs plus related legal fees) cannot be estimated with reasonable certainty. (See "Impact on Financials Statements" section below for further discussion.)

• Insurance Coverage

Our applicable insurance policies generally provide coverage for asbestos liability costs, including coverage for both indemnity and defense costs. Following the initiation of asbestos litigation, an effort was made to identify all of our primary, umbrella and excess level insurance carriers that provided applicable coverage beginning in the 1950s through the mid-1980s. We located primary policies for all such years except for the early 1960s. With respect to this period, we entered into an arrangement with ACE Property & Casualty Insurance Company in 2005, pursuant to which we and they share in asbestos liabilities allocable to such period. We have located umbrella or excess layer policies for all such years except for the period from May 18, 1961 to May 18, 1964. We believe that a policy was purchased from Continental Casualty Company covering this period based upon documents we have found, but the insurer has denied coverage. This policy has not yet been triggered.

Where appropriate, carriers were put on notice of the litigation. Marsh has historically been engaged to work with us to project our insurance coverage for asbestos-related claims. Marsh’s conclusions are based primarily on a review of our coverage history, application of reasonable assumptions on the allocation of coverage consistent with certain industry practices, an assessment of the creditworthiness of the insurance carriers, analysis of applicable deductibles, retentions and policy limits, the experience of NERA and a review of NERA’s reports.

• Cost Sharing Agreement

To date, our insurance carriers have paid for substantially all of the settlement and defense costs associated with our asbestos-related claims. The current cost sharing agreement between us and such insurance carriers is primarily designed to facilitate the ongoing administration and payment of such claims by the carriers until the applicable insurance coverage is exhausted. This agreement, which replaced an older agreement that had expired, can be terminated by election of any party thereto after January 25, 2015. Absent any such election, the agreement will continue until a party elects to terminate it. As of the report filing date for this report, the agreement has not been terminated.

In 2014, the primary layer insurance policies providing coverage for the January 1, 1966 to January 1, 1967 period exhausted. The cost sharing agreement contemplates that any excess carrier over exhausted primary layer carriers will become a party to the cost sharing agreement, replacing the coverage provided by the exhausted primary policies if the carrier providing such excess coverage is not already a party to the cost sharing agreement. The excess carrier providing coverage for the period set forth above is currently providing applicable insurance coverage in accordance with the allocation provisions of the cost sharing agreement, but has not yet signed that agreement.

• Impact on Financial Statements

The models developed for determining the potential exposure and related insurance coverage were developed by outside consultants deemed to be experts in their respective fields with the forecast for asbestos related liabilities generated by NERA and the related insurance receivable projections developed by Marsh. The models contain numerous assumptions that significantly impact the results generated by the models. We believe the assumptions made are reasonable at the present time, but are subject to uncertainty

26

based on the actual future outcome of our asbestos litigation. We determined that a ten year projection period is now appropriate as we have experience in addressing asbestos related lawsuits over the last few years to use as a baseline to project the liability over ten years. However, we do not believe we have sufficient data to justify a longer projection period at this time. As of December 31, 2014, the estimated liability and estimated insurance recovery for the ten year period through 2024 was $56.5 million and $53.0 million, respectively. There were no changes to these projections during the first six months of 2015. 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.

The amounts recorded for the asbestos-related liability 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 will incur additional charges for our asbestos liabilities and defense costs in the future, which could exceed existing reserves, but such excess amount cannot be reasonably estimated at this time. We will continue to vigorously defend ourselves and believe we have substantial unutilized insurance coverage to mitigate future costs related to this matter.

Other Environmental and General Litigation

• In the second quarter of 2010, the CT DEEP contacted us to discuss a disposal site in Killingly, Connecticut. We undertook internal due diligence work related to the site to better understand the issue and our alleged involvement. As a matter of procedure, we have submitted an insurance claim for the disposal site, but we currently do not know the nature and extent of any alleged contamination at the site, how many parties could be potentially involved in any remediation, if necessary, or the extent to which we could be deemed a potentially responsible party. CT DEEP has not made any assessment of the nature of any potential remediation work that may be done, nor have they made any indication of any potential costs associated with such remediation. Therefore, based on the facts and circumstances known to us at the present time, we are not able to estimate the probability of incurring a contingent liability related to this site, nor are we able to reasonably estimate any potential range of exposure at this time. As such, no reserve has been established for this matter at this time. We continually monitor this situation and are in correspondence with the CT DEEP as appropriate. When and if facts and circumstances related to this matter change, we will review our position and our ability to estimate the probability of any potential loss contingencies, as well as the range of any such potential exposure.

• The corporate headquarters of Rogers located in Rogers, Connecticut is part of the Connecticut Voluntary Corrective Action Program (VCAP). As part of this program, we have had conversations with the CT DEEP to begin to determine if any corrective actions need to be taken at the site related to any potential contamination issues. We are currently in the early stages of evaluating this matter and have initiated internal due diligence work related to the site to better understand any potential issues.

As of June 30, 2015, a reserve of $0.1 million was recorded for the continuing assessments to determine the extent of any potential remediation that may be required. However, at this time, it is currently unknown what the nature and extent of any potential contamination is at the site, nor what any potential remediation or associated costs would be if any such issues were found. Therefore, based on the facts and circumstances known to us at the present time, we are unable to estimate the probability of incurring a contingent liability related to environmental remediation at this site, nor are we able to reasonably estimate any potential range of exposure at this time. As such, no reserve specific to environmental remediation activity has been established for this matter at this time.

• In 2013, we became aware of a claim made by a sales agent/distributor in Europe for alleged improper termination of our relationship. The sales agent/distributor is seeking compensation for the terminated relationship. During 2014, a mediation process was initiated and was completed in the first quarter of 2015. We reached a settlement related to this matter in the amount of $0.5 million.

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 – Income Taxes

Our effective income tax rate was 29.0% and 33.9% in the second quarter of 2015 and 2014, respectively. Our effective income tax rate was 30.3% and 31.1% for the six months ended June 30, 2015 and 2014, respectively. In the second quarter of 2015, our income tax rate was unfavorably impacted by a discrete tax expense of approximately $0.4 million due to the redemption of corporate owned life insurance policies, and was favorably impacted by a discrete tax benefit of approximately $1.6 million due to a change in our state tax rate as a result of a legal reorganization undertaken during the quarter. In both the second quarter of 2015, as well as the second quarter of 2014, our income tax rate benefited from favorable tax rates on certain foreign business activity as compared to our statutory tax rate of 35%.

We are subject to income taxes in the United States and in numerous foreign jurisdictions.  No provision is made for U.S. income taxes on the undistributed earnings of substantially all of our wholly-owned foreign subsidiaries because such earnings are indefinitely reinvested in those companies. If circumstances change and it becomes apparent that some or all of the undistributed earnings of our wholly-owned foreign subsidiaries will not be indefinitely reinvested, a provision for the tax consequences, if any, will be recorded in the period in which the circumstances change.

Our accounting policy is to account for interest expense and penalties related to uncertain tax positions as income tax expense.  As of June 30, 2015, we have approximately $1.2 million of accrued interest related to uncertain tax positions included in the $12.4 million of unrecognized tax benefits, $12.3 million of which, if recognized, would impact the effective tax rate.

We are subject to taxation in the U.S. and various state and foreign jurisdictions. Our tax years from 2011 through 2014 are subject to examination by these various tax authorities. With few exceptions, we are no longer subject to U.S. federal, state, local and foreign examinations by tax authorities for years before 2011.

In May 2014, the Financial Accounting Standards Board (FASB) issued a new standard to achieve a consistent application of revenue recognition within the U.S., 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 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. On July 9, 2015, the FASB agreed to delay the effective date by one year. In accordance with the agreed upon delay, the new standard is effective for us beginning in the first quarter of 2018. Early adoption is permitted, but not before the original effective date of the standard. The new standard is required to be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. We have not yet selected a transition method nor have we determined the impact of the new standard on our consolidated condensed financial statements.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

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

Our reporting structure is comprised of the following operating segments: Advanced Connectivity Solutions (ACS), Elastomeric Material Solutions (EMS), Power Electronics Solutions (PES) and the Other segment. We believe this structure aligns our external reporting presentation with how we currently manage and view our business internally. In the second quarter of 2015, the Company concluded that it needed to update two of its operating segment names to better align the business product portfolio offerings to the market. Therefore, Advanced Connectivity Solutions replaces the name of Printed Circuit Materials, and Elastomeric Material Solutions replaces the name of High Performance Foams. There were no changes to the composition of these two operating segments. The Power Electronics Solutions and Other segment names remain unchanged.

Executive Summary

Company Background and Strategy

We are a global enterprise that provides customers with innovative solutions and industry leading products in a variety of markets, including portable communications, communications infrastructure, consumer electronics, safety and protection, automotive, defense and clean technology. We generate revenues and cash flows through the development, manufacture, and distribution of

29

specialty material-based products that are sold to multiple customers, primarily original equipment manufacturers (OEMs) and contract manufacturers that, in turn, produce component products that are sold to end-customers for use in various applications.  As such, our business is highly dependent, although indirectly, on market demand for these end-user products. Our ability to forecast future sales growth is largely dependent on management’s ability to anticipate changing market conditions and how our customers will react to these changing conditions. It is also highly limited due to the short lead times demanded by our customers and the dynamics of serving as a relatively small supplier in the overall supply chain for these end-user products. In addition, our sales represent a number of different products across a wide range of price points and distribution channels that do not always allow for meaningful quantitative analysis of changes in demand or price per unit with respect to the effect on sales and earnings.

Strategically, our current focus is on three megatrends that have fueled growth of our Company: 1) continued growth of the internet and the variety of ways in which it can be accessed, (2) expansion of safety and protection, and (3) further investment in clean technology. These trends and their related markets all require materials that perform to the highest standards, a characteristic which has been a key strength of our products over the years. We are also focused on growing our business both organically and through strategic acquisitions or technology investments that will add to or expand our product portfolio, as well as strengthen our presence in existing markets or expand into new markets. We will continue to focus on business opportunities and invest in expansion around the globe. Our vision is to be the leading innovative, growth oriented, and high technology materials solutions provider for our selected markets. To achieve this vision, we must have an organization that can cost effectively develop, produce and market products and services that provide clear advantages for our customers and markets.

2015 Second Quarter Executive Summary

In the second quarter of 2015, we achieved net sales of $163.1 million, a 6.3% increase from the second quarter of 2014 net sales of $153.5 million. The increase in net sales was comprised of an organic sales decline of 4.9%, a negative currency impact of 5.4% and acquisition growth of 16.5%. Including acquisition growth, net sales in Advanced Connectivity Solutions (ACS) increased 8.0% from $61.5 million in second quarter of 2014 to $66.4 million in the second quarter of 2015 and net sales in Elastomeric Material Solutions (EMS) increased 9.9% from $42.8 million in the second quarter of 2014 to $47.0 million in the second quarter of 2015. These increases were partially offset by a decline in net sales of 10.2% at our Power Electronics Solutions (PES) operating segment from $42.9 million in the second quarter of 2014 to $38.5 million in the second quarter of 2015.

Net income increased by 24.2% to $13.5 million in the second quarter of 2015 from $10.9 million in the second quarter of 2014. In the second quarter of 2015, net income included approximately $0.6 million of expense related to integrating the Arlon acquisition. The improvement in net income was attributable to incremental gross margin contribution and lower selling and administrative expenses compared to the same quarter of the prior year. Gross margin was 37.1% in the second quarter of 2015 compared to 37.2% in the second quarter of 2014. Organic margin performance improved, despite lower organic sales, through operational excellence initiatives across our business units, offset by lower gross margin from the Arlon business.

During the second quarter of 2015, we assessed the names of our business segments and as a result, our Printed Circuit Materials business is now known as Advanced Connectivity Solutions, and our High Performance Foams business is now known as Elastomeric Material Solutions. We feel these names better reflect the capabilities of Rogers, place greater emphasis on the value-added solutions we bring to our customers and take into account the addition of the Arlon business.

On January 22, 2015, we acquired Arlon and its principal subsidiaries (collectively, “Arlon”). As part of the integration process, Arlon operations related to circuit materials and silicones have been included in our ACS and EMS segments, respectively. The Other segment includes the Arlon business that manufactures specialty polyimide and epoxy-based laminates and bonding materials. The legacy Arlon business produced revenues of $25.4 million in the second quarter of 2015, which more than offset the decline in organic sales. We are continuing our integration of Arlon and beginning to capitalize on opportunities to expand our market reach, broaden our portfolio and deepen customer relationships.

Although we had a decline in organic net sales growth, quarter over quarter, going forward, we expect to experience growth in Rogers' applications for wireless telecommunications, automotive safety systems, rail traction, hybrid all-electric vehicles (EV/HEV), energy efficient motor controls, automotive electrification and safety and protective cushioning. We continue to pursue synergistic acquisition opportunities to leverage our global strengths and broaden the portfolio of solutions that we provide our customers. We believe that many opportunities for added growth exist, particularly as we expand our presence across new markets and regions, as well as further diversify our product portfolio in the markets we serve today.

Net Sales

Net sales increased by 6.3% to $163.1 million in the second quarter of 2015 from $153.5 million in the second quarter of 2014. The net sales increase was composed of organic sales decline of 4.9%, negative currency impact of 5.4% and acquisition related growth of 16.5%. The ACS operating segment net sales increased 8.0%: organic sales decline of 13.3% and a negative currency impact of 1.2%, which partially offset the acquisition growth of 22.5%. The EMS operating segment net sales increased 9.9%: organic sales decline of 4.0% and a negative currency impact of 1.7%, which partially offset the acquisition growth of 15.5%. The PES operating segment net sales declined 10.2%: organic sales growth of 5.3% offset by a negative currency impact of 15.5%.

On a year to date basis, net sales increased by 9.3% to $328.1 million in the first half of 2015 from $300.1 million in the first half of 2014. The increase in net sales was composed of a organic sales decline of 0.9%, negative currency impact of 4.9% and acquisition related growth of 15.2%. The ACS operating segment net sales increased 14.7%: organic sales decline of 4.2% and negative currency impact of 1.3%, which partially offset acquisition growth of 20.3%. The EMS operating segment net sales increased 9.0%: organic sales decline of 3.6% and negative currency impact of 1.6%, which partially offset acquisition growth of 14.2%. The PES operating segment net sales declined 7.9%: organic sales growth of 6.1% offset by a negative currency impact of 14.0%.

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

Gross Margin

Gross margin as a percentage of net sales was 37.1% in the second quarter of 2015 compared to 37.2% in the second quarter of 2014. Organic gross margin improved 60 basis points, despite lower organic net sales, due to our operational excellence initiatives, combined with favorable product mix at PES and favorable inventory absorption at ACS. These improvements substantially offset the impact of lower gross margin contribution, of 70 basis points, from the Arlon business.

On a year to date basis, gross margin as a percentage of net sales increased by 50 basis points to 37.5% in the first half of 2015 from 37.0% in the first half of 2014. The gross margin for the first half of 2015 included approximately $1.7 million of purchase accounting expenses related to the Arlon acquisition, of which, $1.6 million was the non-recurring fair value adjustment for inventory. The year over year improvement was primarily the result of improvements in supply chain, product quality and procurement, which favorably impacted margin performance. In addition, increases to inventory resulted in a favorable absorption impact, which was partially offset by the lower organic net sales and lower gross margin related to the Arlon business.

31

Selling and Administrative Expenses

Selling and administrative expenses decreased 4.3% to $33.0 million in the second quarter of 2015 from $34.5 million in the second quarter of 2014. Second quarter 2015 results included approximately $0.6 million in integration expenses related to the Arlon acquisition. The lower expenses are primarily attributable to $2.9 million of lower incentive compensation costs relative to 2014 and other discrete items incurred in the second quarter of 2014 related to the CFO transition, severance and other costs totaling $1.9 million. In addition, lower operational spending resulted in a decrease of $1.7 million as compared to the second quarter of 2014. Partially offsetting these amounts are increases in expenses due to a variety of factors, including $3.9 million of selling and administrative expenses related to the Arlon business (including $1.6 million of amortization associated with the acquisition) and $0.5 million of defined benefit pension plan costs.

On a year to date basis, selling and administrative expenses increased 11.4% to $69.2 million in the first half of 2015 from $62.1 million in the first half of 2014. Year to date 2015 results included approximately $4.9 million in integration expenses related to the Arlon acquisition. Additional increases in expenses were due to a variety of factors, including $7.0 million of selling and administrative expenses related to the Arlon business (including $2.7 million of amortization associated with the acquisition) and $0.9 million of defined benefit pension plan costs. These increases were partially offset by $2.7 million of lower incentive compensation costs in 2015 and discrete items incurred in the second quarter of 2014 related to the CFO transition, severance and other cost increases of $1.9 million. In addition, lower operational spending resulted in a decrease of $1.1 million as compared to the first half of 2014.

Research and Development Expenses

Research and development (R&D) expenses increased 9.9% to $7.1 million in the second quarter of 2015 from $6.4 million in the second quarter of 2014. As a percentage of net sales, R&D costs increased to 4.3% of net sales in the second quarter of 2015 from 4.2% of net sales in the second quarter of 2014. Year to date, R&D expenses increased 16.6% to $13.2 million in the first half of 2015 from $11.3 million in the first half of 2014. As a percentage of net sales, R&D costs increased to 4.0% in the first half of 2015 from 3.8% of net sales in the first half of 2014. From a gross spending perspective, we are increasing investments that are targeted at developing new platforms and technologies focused on long term growth initiatives, as evidenced by our partnership with Northeastern University in Boston, Massachusetts.

Equity Income in Unconsolidated Joint Ventures

Equity income in unconsolidated joint ventures declined to approximately $0.4 million in the second quarter of 2015 from $1.1 million in the second quarter of 2014. On a year to date basis, equity income in unconsolidated joint ventures declined to $1.3 million in the first half of 2015 from $2.0 million in the first half of 2014. The decreases were due to lower demand, the product mix and unfavorable currency exchange rate shifts.

Other Income (Expense), Net

In the second quarter of 2015, other income (expense), net, was expense of $0.5 million as compared to an expense of $0.1 million in the second quarter of 2014. The increase in expense was primarily attributable to unfavorable mark to market adjustments related to copper hedging contracts.

On a year to date basis, in the first half of 2015 we recognized expense of approximately $0.6 million as compared to an expense of $1.3 million in the first half of 2014. The difference in these amounts was primarily related to less unfavorable mark to market adjustments related to copper hedging contracts and less unfavorable foreign currency transaction costs.

Interest Income (Expense), Net

Interest income (expense), net, increased by 81.0% to $1.3 million of expense in the second quarter of 2015 from $0.7 million of expense in the second quarter of 2014. On a year to date basis, interest income (expense), net, increased by 57.3% to $2.3 million of expense in the first half of 2014 to $1.5 million of expense in the first half of 2015. The increase quarter over quarter and year over year was due to interest on the long term debt associated with the Arlon acquisition, which occurred in January of 2015.

Income Taxes

Our effective income tax rate was 29.0% and 33.9% in the second quarter of 2015 and 2014, respectively. Our effective income tax rate was 30.3% and 31.1% for the six months ended June 30, 2015 and 2014, respectively. In the second quarter of 2015, our income tax rate was unfavorably impacted by a discrete tax expense of approximately $0.4 million due to the redemption of corporate owned life insurance policies, and was favorably impacted by a discrete tax benefit of approximately $1.6 million due to a change in our state tax rate as a result of a legal reorganization undertaken during the quarter. In both the second quarter of 2015, as well as the second quarter of 2014, our income tax rate benefited from favorable tax rates on certain foreign business activity as compared to our statutory tax rate of 35%.

The acquisition of Arlon added 78.1% sales growth as compared to the same period in the prior year. There was also stronger demand for elastomer rollers and floats products, which increased 1.1% quarter over quarter. Net sales were unfavorably impacted by 1.6% due currency fluctuations.

Operating income remained consistent at $2.1 million for both the second quarter of 2015 and the second quarter of 2014. As a percentage of net sales, second quarter of 2015 operating income was 18.9%, as compared to the 33.3% achieved in the second quarter of 2014. The decline as a percentage of sales was a result of the additional Arlon sales having lower operating margins.

YTD 2015 versus YTD 2014

Net sales increased by 76.3% to $21.8 million in the first half of 2015 from $12.4 million in the first half of 2014. The acquisition of Arlon added 75.7% sales growth as compared to the same period in the prior year. There was also stronger demand for elastomer rollers and floats products, which increased 2.3% quarter over quarter. Net sales were unfavorably impacted by 1.7% due to currency fluctuations.

35

Operating income decreased to $4.0 million in the first half of 2015 from $4.3 million in the first half of 2014. The decline was primarily due to $0.6 million of integration expenses related to the Arlon acquisition that are included in the first half of 2015 results.

Liquidity, Capital Resources and Financial Position

We believe that our ability to generate cash from operations to reinvest in our business is one of our fundamental strengths. We believe that our existing sources of liquidity and future cash flows that are expected to be generated from our operations, together with our available credit facilities, will be sufficient to fund our operations, capital expenditures, research and development efforts, and debt service commitments, as well as our other operating and investing needs, for at least the next twelve months. We continue to have access to the remaining portion of the line of credit available under the Amended Credit Agreement (as defined in the Credit Facilities section which follows), should any issue or strategic opportunities arise. We continually review and evaluate the adequacy of our cash flows, borrowing facilities and banking relationships to ensure that we have the appropriate access to cash to fund both our near-term operating needs and our long-term strategic initiatives.

Cash provided by (used in) financing activities	124,387			5,498

At the end of the second quarter of 2015, cash and cash equivalents were $209.8 million as compared to $237.4 million at the end of 2014, a decrease of $27.6 million, or approximately 11.6%. This decrease was due primarily to $34.7 million being disbursed for the acquisition of Arlon, $14.3 million in capital expenditures, $6.5 million in a contribution to our defined benefit plans and $5.0 million in required debt payments, partially offset by strong cash generated from operations and the receipt of $6.5 million related to stock option exercises.

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)	June 30, 2015		December 31, 2014
U.S.	$	48,453	$	96,721
Europe	80,980		71,802
Asia	80,329		68,852
Total cash and cash equivalents	$	209,762	$	237,375

Cash held in certain foreign locations could be subject to additional taxes if we repatriated such amounts back to the U.S. from foreign countries that have a lower tax rate than in the U.S.  Our current policy is that the historical earnings and cash in these locations will be permanently reinvested in those foreign locations.

37

Significant changes in our balance sheet accounts from December 31, 2014 to June 30, 2015 were as follows:

◦ Inventory increased to $87.0 million in the first half of 2015 by 26.8% from $68.6 million at December 31, 2014. This overall increase is attributable to $10.0 million of inventory held by Arlon and higher levels of inventory held by the ACS operating segment due a combination of a slowdown in wireless telecommunications demand and this operating segment optimizing inventory levels.

◦ Property, plant and equipment, increased by 20.7% to $181.5 million from $150.4 million. The increase was primarily due to the acquisition of Arlon, which increased property, plant and equipment by $32.6 million and was slightly offset by depreciation.

◦ Goodwill and other intangible assets increased by 81.9% and 110.4% to $178.6 million and $80.6 million from $98.2 million and $38.3 million, respectively. These increases were due to the acquisition of Arlon.

◦ Outstanding borrowings on credit facilities (short term and long term) increased by 200% to $180.0 million from $60.0 million. The increase was due to financing of $125.0 million for the acquisition of Arlon, offset by $5.0 million in principal repayments.

Credit Facilities

On June 18, 2015, we entered into a secured five year credit agreement (the "Amended Credit Agreement"). The Amended Credit Agreement amends and restates the credit agreement signed between the Company and the same banks on July 13, 2011 and increased our borrowing capacity from $265.0 million to $350.0 million, with an additional $50.0 million expansion option.

The Amended Credit Agreement provides (1) a $55.0 million term loan; (2) up to $295.0 million of revolving loans, with sub-limits for multicurrency borrowings, letters of credit and swing-line notes; and (3) a $50.0 million expansion 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 Amended Credit Agreement).  

Borrowings under the Amended Credit Agreement bear interest based on one of two options. 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 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 Amended Credit Agreement, the Company is required to pay a quarterly fee of 0.20% to 0.30% (based upon our leverage ratio) of the unused amount of the lenders’ commitments under the Amended Credit Agreement.

The Amended Credit Agreement contains customary representations, warranties, covenants, mandatory prepayments and events of default under which the Company's payment obligations may be accelerated. The financial covenants include requirements to maintain (1) a leverage ratio of no more than 3.25 to 1.00, subject to a one-time 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 ("ICR") of no less than 3.00 to 1.00. The ICR is the ratio determined as of the end of each of its fiscal quarters ending on and after June 30, 2015, of (i) Consolidated Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) (as defined in the Amended Credit Agreement) minus the unfinanced portion of Consolidated Capital Expenditures to (ii) Consolidated Interest Expense paid in cash, in each case for the period of four consecutive fiscal quarters ending with the end of such fiscal quarter, all calculated for the Borrower and its subsidiaries on a consolidated basis.

As of June 30, 2015, we were in compliance with all of the financial covenants in the Amended Credit Agreement, as we achieved actual ratios of approximately 1.34 to 1.00 on the leverage ratio and 30.68 to 1.00 on the ICR.

The Amended Credit Agreement requires the mandatory quarterly repayment of principal on amounts borrowed under such term loan. Payments will commence on September 30, 2015, and are scheduled to be completed on June 30, 2020. The aggregate mandatory principal payments due are as follows:

2015	$1.4	million
2016	$3.4	million
2017	$4.1	million
2018	$4.8	million
2019	$5.5	million
2020	$160.8	million

38

All obligations under the Amended Credit Agreement are guaranteed by each of the Corporation’s existing and future material domestic subsidiaries, as defined in the Amended Credit Agreement (the “Guarantors”). The obligations are also secured by a Second Amended and Restated Pledge and Security Agreement, dated as of June 18, 2015, entered into by the Company 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 Company and the Guarantors.

All amounts borrowed or outstanding under the Amended Credit Agreement, with the exception of amounts borrowed under the term loan which are subject to quarterly principal payments, are due and mature on June 18, 2020, unless the commitments are terminated earlier either at the request of the Company or if certain events of default occur. At June 30, 2015, the Company had outstanding debt of $180.0 million under the Amended Credit Agreement which included $55.0 million borrowed under the term loan and $125.0 million borrowed under the revolving line of credit.

In addition, as of June 30, 2015 we had a $1.4 million standby letter of credit (LOC) to guarantee Rogers workers compensation plans that were backed by the Amended Credit Agreement. No amounts were drawn on the LOC as of June 30, 2015 or December 31, 2014.

The Amended Credit Agreement is secured by many of the assets of Rogers, including but not limited to, receivables, equipment, intellectual property, inventory, and stock in certain subsidiaries.

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.  

Before entering into the Amended Credit Agreement, we had $0.5 million of remaining capitalized costs from the previous credit agreements. These costs will continue to be amortized over the life of the Amended Credit Agreement. In the second quarter of 2015, we capitalized an additional $1.6 million in connection with the Amended Credit Agreement. These costs will be amortized over the life of the Amended Credit Agreement, which will terminate in June 2020. 

We incurred amortization expense of $0.1 million in each of the second quarters of 2015 and 2014, and amortization expense of $0.2 million in each of the first six months of 2015 and 2014. At June 30, 2015, we have approximately $2.1 million of credit facility costs remaining to be amortized.

We borrowed $125.0 million under the line of credit in the first quarter of 2015 to fund the acquisition of Arlon. During the first six months of 2015 and 2014, we made principal payments of $5.0 million and $7.5 million, respectively, on the outstanding debt. The principal amount of this debt has been transferred to the new revolving credit line created in June of 2015. We are obligated to pay $2.8 million on this debt obligation in the next 12 months under the term loan.

We incurred interest expense on our outstanding debt of $1.1 million and $1.9 million for the three and six month periods ended June 30, 2015, respectively, and $0.5 million and $1.0 million for the three and six month periods ended June 30, 2014, respectively.

We incurred an unused commitment fee of $0.1 million and $0.1 million for the three and six month periods ended June 30, 2015 and $0.1 million and $0.2 million for the three and six month periods ended June 30, 2014, respectively. In July 2012, we entered into an interest rate swap to hedge the variable interest rate on our term loan debt. As of June 30, 2015, the remaining notional amount of the interest rate swap covers $32.5 million of our term loan debt. At June 30, 2015, our outstanding debt balance is comprised of a term loan of $55.0 million and $125.0 million borrowed on the revolving line of credit. At June 30, 2015, the rate charged on this debt is the 1 month LIBOR at 0.1875% plus a spread of 1.625%.

Pursuant to the Amended Credit Agreement, we cannot make a cash dividend payment if (i) a default or event of default has occurred and is continuing or will result from the cash dividend payment or (ii) if the aggregate amount of all cash dividend payments and other such restricted payments (as defined in the Amended Credit Agreement) that are otherwise not permitted during any fiscal year exceeds $10.0 million; provided that, if at the time of and immediately after giving effect (including on a pro forma basis) thereto, the Leverage Ratio (as defined in the Amended Credit Agreement) is less than or equal to 2.00 to 1.00, such dollar limitation would not apply.

Capital Lease

During the first quarter of 2011, we recorded a capital lease obligation related to the acquisition of Curamik Electronics GmbH ("Curamik") for its primary 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 June 30, 2015 is $6.1 million. Depreciation expense related to the capital lease was $0.1 million in each of the three month periods ended June 30, 2015 and 2014 and $0.2 million in the six month periods ending June 30, 2015 and 2014. Accumulated depreciation at June 30, 2015 and December 31, 2014 was $1.8 million and $1.6 million, respectively. These expenses are included as depreciation expense in cost of sales on our condensed consolidated statements of income.

39

We also incurred interest expense on the capital lease of $0.1 million and $0.2 million for the three and six month periods ended June 30, 2015, respectively, and $0.1 million and $0.3 million for the three and six month periods ended June 30, 2014, respectively. Interest expense related to the debt recorded on the capital lease is included in interest expense on the condensed consolidated statements of income.

We guarantee an interest rate swap related to our lease of the manufacturing facility in Eschenbach, Germany. The swap is in a liability position with the bank at June 30, 2015, and has a fair value of $0.3 million. We have concluded that default by the lessor is not probable during the term of the swap, and we have chosen not to exercise the option to buyout the lease during the leasing period; therefore, the guarantee has no value. For more information about the manufacturing facility, see Capital Lease section below.

Contingencies

During the second quarter of 2015, we did not become aware of any new material developments related to environmental matters or other contingencies. We have not had any material recurring costs and 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 contingency matters.

Off-Balance Sheet Arrangements

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

There have been no material changes in our critical accounting policies during the second quarter of 2015.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no significant changes in our exposure to market risk during the second quarter of 2015. For discussion of our exposure to market risk, refer to Item 7A, Quantitative and Qualitative Disclosures About Market Risk, contained in our 2014 Annual Report on Form 10-K.

Item 4. 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 under Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of June 30, 2015. The Company's disclosure controls and procedures are designed to (i) 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 our management, including our 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 June 30, 2015.

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) under the Exchange Act.

Exhibit 10. 1

OFFICER SPECIAL SEVERANCE AGREEMENT

This Officer Special Severance Agreement (this “Agreement”), effective on ______________, 20__ (the “Effective Date”), is made between Rogers Corporation, a Massachusetts corporation, (herein referred to as the “Company”) and __________________ (the “Officer”). The Company and the Officer are collectively referred to herein as the “Parties” and individually referred to as a “Party.”

WITNESSETH THAT

WHEREAS, the Officer is employed by the Company or provides services directly or indirectly to the Company as a senior executive of the Company or one, or more than one, of the Company’s subsidiaries; and

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that the Company should provide certain compensation and benefits to the Officer in the event that the Officer’s employment is terminated on or after a change in the ownership or control of the Company under certain circumstances on the terms set forth below.

NOW, THEREFORE, in consideration of the promises and the mutual covenants contained herein, the parties hereto agree as follows:

1. Purpose. The Company considers a sound and vital management team to be essential. Management personnel who become concerned about the possibility that the Company may undergo a Change in Control (as defined in Paragraph 2 below) may terminate employment or become distracted. Accordingly, the Board has determined to extend this Agreement to minimize the distraction the Officer may suffer from the possibility of a Change in Control.

2. Change in Control. The term “Change in Control” for purposes of this Agreement shall mean the earliest to occur of the following events during the Term (as defined in Paragraph 3(d) below):

(a) closing of the sale of all or substantially all of the assets of the Company on a consolidated basis to an unrelated person or entity,

(b) closing of the sale of all of the Company’s common stock to an unrelated person or entity,

(c) there is a consummation of any merger, reorganization, consolidation or share exchange unless the persons who were the beneficial owners of the outstanding shares of the common stock of Company immediately before the consummation of such transaction beneficially own more than 50% of the outstanding shares of the common stock of the successor or survivor entity in such transaction immediately following the consummation of such transaction. For purposes of this Paragraph 2(c), the percentage of the beneficially owned shares of the successor or survivor entity described above shall be determined exclusively by reference to the shares of the successor or survivor entity which result from the beneficial ownership of shares of common stock of the Company by the persons described above immediately before the consummation of such transaction.

3. Term.

(a) The term of this Agreement shall be the period beginning on the Effective Date and ending on the third anniversary of the Effective Date; provided, however, that:

(i) the term of this Agreement shall be automatically extended thereafter for successive three year periods unless, at least ninety (90) days prior to the third anniversary of the Effective Date or twelve months prior to the then current succeeding three-year extended term of this Agreement, either Party has notified the other Party that the term hereunder shall expire at the end of the then-current term; and

(ii) if a Change in Control occurs prior to the scheduled expiration of the term of this Agreement as described above, the term of this Agreement shall automatically be extended until the second anniversary of such Change in Control (the “Protection Period”).

(b) If no Change in Control occurs prior to expiration of the Term or if the Officer Separates from Service (as defined in Paragraph 4(a) below) before a Change in Control, this Agreement shall automatically terminate without any further action; provided, however, that Paragraph 13 (regarding arbitration) shall continue to apply to the extent the Officer disputes the termination of this Agreement.

(c) The obligations of the Company and the Officer under this Agreement which by their nature may require either partial or total performance after its expiration shall survive any such expiration.

(d) The initial term of this Agreement, as it may be extended or terminated under this Paragraph 3, is herein referred to as the “Term.”

4. Severance Benefits. If, during the Protection Period (as defined in Paragraph 3(a)(ii) above), the Officer “Separates from Service” (as defined below) due to termination of employment by the Company and its subsidiaries without “Cause” (as defined in Paragraph 5(a)) or by the Officer due to “Constructive Termination” (as defined in Paragraph 5(b)) (each, a “Qualifying Termination”), the Officer shall be entitled to the severance benefits set forth in this Paragraph 4. The term “Separation from Service” or “Separates from Service” for purposes of this Agreement shall mean a “separation from service” within the meaning of Section 409A of the Code. The Officer shall not be entitled to severance benefits upon any other Separation from Service, including due to the Officer’s death or Disability (as defined in Paragraph 5(c)). The payments and benefits provided for under this Paragraph 4 shall be in lieu of (or offset by) any other severance benefits or other benefits in exchange for a non-competition agreement to which the Officer may have been entitled under any other plan, program or policy of the Company (or subsidiary) or agreement covering the Officer. Payment of the severance benefits set forth below shall be subject to the Officer’s timely execution of a release that is not revoked as provided in Paragraph 6 below and the Officer entering into the “Non-Compete Agreement” (as defined and provided in Paragraph 7 below).

(a) Salary and Bonus Amount. The Company will pay to the Officer thirty days after a Qualifying Termination a lump sum cash amount equal to the product obtained by multiplying (i) the sum of (A) salary at the annualized rate which was being paid by the Company and/or subsidiaries to the Officer immediately prior to the time of such termination or, if greater, at the time of the Change in Control plus (B) the annual target bonus and/or any other annual

cash bonus awards last determined for the Officer or, if greater, most recently paid prior to the Change in Control, (ii) by two and one-half (2.5).

(b) Pro-Rata Bonus. The Officer shall be entitled to receive a lump sum cash amount based upon the actual performance for the year in which Separation from Service occurs, pro-rated based on the number of days the Officer was employed during such year. The pro-rata bonus will be paid not later than March 15th of the calendar year that immediately follows the year of the Officer’s Qualifying Termination.

(c) Welfare Benefits. The Officer shall be entitled for a period of thirty (30) consecutive months following the month in which a Qualifying Termination occurs to receive medical, dental and life insurance benefits that are similar in all material respects as those benefits provided under the Company’s employee benefit plans, policies and programs to senior executives of Company who have not terminated their employment (collectively, such benefits are referred to hereinafter as the “Welfare Benefits”), at no greater monthly cost to the Officer than the cost paid by such senior executives. If the Company cannot provide such benefits under its employee benefit plans, policies and programs the Company either shall provide such benefits to the Officer outside such plans, policies and programs at no additional expense or tax liability to the Officer or shall reimburse the Officer for the Officer’s cost to purchase such benefits and for any tax liability for any such reimbursement. The continuation period for medical and dental benefits Section 4980B of the Code (COBRA) shall commence at the end the Officer’s Severance Period. Benefits otherwise receivable by the Officer pursuant to this Paragraph 4(c) shall be reduced to the extent comparable benefits are actually received by or made available to the Officer (other than benefits available at the Officer’s sole expense pursuant to COBRA) during the thirty (30) month continuation period provided in this Paragraph 4(c) (and any such benefits actually received or made available to the Officer shall be reported to the Company by the Officer).

To the extent the continuation of the Welfare Benefits under this Paragraph 4(c) is, or ever becomes, taxable to the Officer and to the extent the Welfare Benefits continue beyond the period in which the Officer would be entitled (or would, but for this Agreement, be entitled) to continuation coverage under a group health plan of the Company under COBRA if the Officer elected such coverage and paid the applicable premiums, the Company shall administer such continuation of coverage consistent with the following additional requirements as set forth in Treas. Reg. § 1.409A-3(i)(1)(iv):

(i) the Officer’s eligibility for Welfare Benefits in one year will not affect the Officer’s eligibility for Welfare Benefits in any other year (disregarding any limit on the amount of Welfare Benefits that may be reimbursed during such continuation period);

(ii) any reimbursement of eligible expenses will be made on or before the last day of the year following the year in which the expense was incurred; and

(iii) the Officer’s right to Welfare Benefits is not subject to liquidation or exchange for another benefit.

(d) Company Car Amount. If the Officer, as of the Qualifying Termination, either was receiving a monthly car allowance or had a company-leased car, any such car allowance will be discontinued as of the date of termination of employment and any such company-leased car

must be returned to the Company within thirty (30) days after the date of termination of employment. No cash payment shall be made due to termination of the company car amount.

(e) Outplacement Services. In the event of a Qualifying Termination, the Company shall provide to the Officer executive outplacement services provided on a one-to-one basis by a senior counselor of a firm nationally recognized as a reputable national provider of such services for up to six months, plus evaluation testing, at a location mutually agreeable to the Parties.

(f) Equity Awards. The vesting of the Officer’s Equity Awards shall be governed by this Section 4(f). The term “Equity Award” shall mean stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares or any other form of award that is measured with reference to the Company’s common stock.

(g)

(i) The vesting of the Officer’s Equity Awards that vest solely on the basis of continued employment with the Company or any of its subsidiaries or affiliates shall be accelerated solely by reason of a Change in Control only if the surviving corporation or acquiring corporation following a Change in Control refuses to assume or continue the Officer’s Equity Awards or to substitute similar Equity Awards for those outstanding immediately prior to the Change in Control. If such Officer’s Equity Awards are so continued, assumed or substituted and at any time after the Change in Control the Officer incurs a Qualifying Termination, then the vesting and exercisability of all such unvested Equity Awards held by the Officer shall be accelerated in full and any reacquisition rights held by the Company with respect to an Equity Award shall lapse in full, in each case, upon such termination.

(ii) The vesting of the Officer’s Equity Awards that vest, in whole or in part, based upon achieving Performance Criteria shall be accelerated on a pro rata basis by reason of a Change in Control. The pro rata vesting amount shall be determined in good faith by the Compensation and Organization Committee based upon (A) the extent to which the Performance Criteria for any such award has been achieved after evaluating actual performance from the start of the performance period until the date of the Change in Control and equitably adjusting performance targets for the shortened period during which the Performance Criteria could be achieved, and (B) the number of days the Officer was employed during the award’s performance period as of the date of the Change in Control.

(iii) For purposes of this Section 4(f), “Performance Criteria” means any business criteria that apply to the Officer, a business unit, division, subsidiary, affiliate, the Company or any combination of the foregoing.

(iv) Enforcement of the terms of this Paragraph 4(f) shall survive termination of this Agreement.

(h) Limitation on Amounts. Notwithstanding any provision of this Agreement to the contrary, if it is determined that part or all of the compensation and benefits payable to the Officer (whether pursuant to the terms of this Agreement or otherwise) before application of this Paragraph 4(g) would constitute “parachute payments” under Section 280G of the Code, and the payment thereof would cause the Officer to incur the 20% excise tax under Section 4999 of the Code (or its successor), the following provisions shall apply:

(i) The amounts otherwise payable to or for the benefit of the Officer pursuant to this Agreement (or otherwise) that, but for this Paragraph 4(g) would be “parachute payments,” (referred to below as the “Total Payments”) shall be reduced to an amount equal to three times the “base amount” (as defined under Section 280G) less $1,000 in a manner that maximizes the net after-tax amount payable to the Officer, as reasonably determined by the Consultant (as defined below).

(ii) All determinations under this Paragraph 4(g) shall be made by a nationally recognized accounting, executive compensation or law firm appointed by the Company (the “Consultant”) that is acceptable to the Officer on the basis of “substantial authority” (within the meaning of Section 6662 of the Code). The Consultant’s fee shall be paid by the Company. The Consultant shall provide a report to the Officer that may be used by the Officer to file the Officer’s federal tax returns.

(iii) It is possible that payments will be made by the Company which should not have been made (each, an “Overpayment”) due to the uncertain application of Section 280G of the Code at the time of a determination hereunder. In the event that there is a final determination by the Internal Revenue Service, or a final determination by a court of competent jurisdiction, that an Overpayment has been made, any such Overpayment shall be repaid by the Officer to the Company together with interest at the prime rate of interest in effect on the date of such Overpayment; provided, however, that no amount shall be payable by the Officer to the Company if and to the extent such payment would not reduce the amount which is subject to taxation under Section 4999 of the Code.

By accepting severance benefits under this Paragraph 4, the Officer waives the Officer’s right, if any, to have any payment made under this Paragraph 4 taken into account to increase the benefits otherwise payable to, or on behalf of, the Officer under any employee benefit plan, policy or program, whether qualified or nonqualified, maintained by the Company.

5. Definitions of “Cause,” “Constructive Termination,” and “Disability”.

(a) For purposes of this Agreement, “Cause” means (i) the Officer’s conviction of (or a plea of guilty or nolo contendere to) a felony or any other crime involving moral turpitude, dishonesty, fraud, theft or financial impropriety; or (ii) a determination by a majority of the Board in good faith that the Officer has (A) willfully and continuously failed to perform substantially the Officer’s duties (other than any such failure resulting from the Officer’s Disability or incapacity due to bodily injury or physical or mental illness), after a written demand for substantial performance is delivered to the Officer by the Board that specifically identifies the manner in which the Board believes that the Officer has not substantially performed the Officer’s duties, (B) engaged in illegal conduct, an act of dishonesty or gross misconduct, or (C) willfully violated a material requirement of the Company’s code of conduct or the Officer’s fiduciary duty to the Company, including the covenant not to compete under Paragraph 7 below. No act or failure to act on the part of the Officer shall be considered “willful” unless it is done, or omitted to be done, by the Officer in bad faith and without reasonable belief that the Officer’s action or omission was in, or not opposed to, the best interests of the Company or its subsidiaries. In order to terminate the Officer’s employment for Cause, the Company shall be required to provide the Officer a reasonable opportunity to be heard (with counsel) before the Board, which shall include at least ten (10) business days of advance written notice

to the Officer. Further, the Officer’s attempt to secure employment with another employer that does not breach the non-competition covenants set forth in Paragraph 7 below shall not constitute an event of “Cause”.

(b) For purposes of this Agreement, “Constructive Termination” means, without the express written consent of the Officer, the occurrence of any of the following during the Protection Period (as defined in Paragraph 3(a)(ii) above):

(i) a material reduction in the Officer’s annual base salary as in effect immediately prior to a Change in Control or as the same may be increased from time to time, and/or a material failure to provide the Executive with an opportunity to earn annual incentive compensation and long-term incentive compensation at least as favorable as in effect immediately prior to a Change in Control or as the same may be increased from time to time;

(ii) a material diminution in the Officer’s authority, duties, or responsibilities as in effect at the time of the Change in Control;

(iii) a material diminution in the authority, duties, or responsibilities of the supervisor to whom the Officer is required to report (it being understood that if the Officer reports to the Board, a requirement that the Officer report to any individual or body other than the Board will constitute “Constructive Termination” hereunder);

(iv) a material diminution in the budget over which the Officer retains authority;

(v) the Company’s requiring the Officer to be based anywhere outside a fifty mile radius of the Company’s offices at which the Officer is based as of immediately prior to a Change in Control (or any subsequent location at which the Officer has previously consented to be based) except for required travel on the Company’s business to an extent that is not substantially greater than the Officer’s business travel obligations as of immediately prior to a Change in Control or, if more favorable, as of any time thereafter; or

(vi) any other action or inaction that constitutes a material breach by the Company or any of its subsidiaries of the terms of this Agreement.

In no event shall the Officer be entitled to terminate employment with the Company on account of “Constructive Termination” unless the Officer provides notice of the existence of the purported condition that constitutes “Constructive Termination” within a period not to exceed ninety (90) days of its initial existence, and the Company fails to cure such condition (if curable) within thirty (30) days after the receipt of such notice.

(c) For purposes of this Agreement, “Disability” means the Officer’s inability, due to physical or mental incapacity resulting from injury, sickness or disease, for one hundred and eighty (180) days in any twelve-month period to perform his duties hereunder.

6. Release. The Officer agrees that the Company will have no obligations to the Officer under Paragraph 4 above until the Officer executes a release in substantially the form which is attached as Exhibit A to this Agreement and, further, will have no further obligations to the Officer under Paragraph 4 if

the Officer revokes such release. The Officer shall have 21 days after a Qualifying Termination to consider whether or not to sign the release. If the Officer fails to return an executed release to the Company’s Vice President of Human Resources within such 21 day period, or the Officer subsequently revokes a timely filed release, the Company shall have no obligation to pay any amounts or benefits under Paragraph 4 of this Agreement.

7. Non-Compete Agreement. By signing this Agreement, the Officer specifically acknowledges that the Severance Benefits payable under Paragraph 4 are expressly conditioned upon the Officer entering into the Non-Compete Agreement in substantially the same form as attached as Exhibit B to this Agreement (“Non-Compete Agreement”) within 21 days after a Qualifying Termination. The Officer agrees that it is the intention of the parties that the Severance Benefits provided to Officer under Paragraph 4 of this Agreement are conditioned upon strict compliance with the Non-Compete Agreement by the Officer. If the Officer breaches (or threatens to breach) any obligations under the Non-Compete Agreement, then, in addition to any other legal or equitable remedies that may be available to the Company, its subsidiaries or affiliates, under the Non-Compete Agreement or otherwise:

(a) the Officer shall forthwith repay to the Company a percentage of the total lump sum amount paid by the Company to the Officer under Paragraph 4(a) and 4(b) equal to X/12, where X equals 36 less the number of months from Separation from Service to the date of the Officer’s breach (or threatened breach) of the Non-Compete Agreement;

(b) the Officer shall not be entitled to receive any further Welfare Benefits at the Company’s expense as provided for Paragraph 4(c) or reimbursement or other payment of outplacement assistance under Paragraph 4(e); and

(c) all unvested Equity Awards shall forthwith be cancelled and terminated, notwithstanding the provisions of any agreements to the contrary.

The Officer agrees that should all or any part or application of the Non-Compete Agreement be held or found invalid or unenforceable for any reason whatsoever by a court of competent jurisdiction in an action between the Officer and the Company (and/or its subsidiaries), the Company nevertheless shall be entitled to take the actions described in Paragraph 7(a), (b) and (c) above, if the Officer breaches or threatens to breach any of the obligations set forth in the Non-Compete Agreement. The provisions of this Paragraph 7 shall survive termination of this Agreement. The parties agrees that any prior written agreement, arrangement or understanding between the Officer and the Company, its subsidiaries or affiliates relating to the Officer’s post-employment obligations, including any covenant not to compete, shall not apply to any employment termination on and after a Change in Control, and the Company, its subsidiaries and affiliates shall have no payment obligations under any such agreement, arrangement or understanding.

8. No Interference with Other Vested Benefits. Regardless of the circumstances under which the Officer may terminate from employment, the Officer shall have a right to any benefits under any employee benefit plan, policy or program maintained by the Company which the Officer had a right to receive under the terms of such employee benefit plan, policy or program after a termination of the Officer’s employment without regard to this Agreement. The Company shall within thirty (30) days of Separation from Service pay the Officer any earned but unpaid base salary and bonus, shall promptly pay the Officer for any earned but untaken vacation and shall promptly reimburse the Officer for any incurred but unreimbursed expenses which are otherwise reimbursable under the Company’s expense

reimbursement policy as in effect for senior executives immediately before the Officer’s employment termination.

9. Consolidation or Merger. If the Company is at any time before or after a Change in Control merged or consolidated into or with any other corporation, association, partnership or other entity (whether or not the Company is the surviving entity), or if substantially all of the assets thereof are transferred to another corporation, association, partnership or other entity, the provisions of this Agreement will be binding upon and inure to the benefit of the corporation, association, partnership or other entity resulting from such merger or consolidation or the acquirer of such assets (collectively, “acquiring entity”) unless the Officer voluntarily elects not to become an employee of the acquiring entity as determined in good faith by the Officer. Furthermore, in the event of any such consolidation or transfer of substantially all of the assets of the Company, the Company shall enter into an agreement with the acquiring entity that shall provide that such acquiring entity shall assume this Agreement and all obligations and liabilities under this Agreement; provided, that the Company’s failure to comply with this provision shall not adversely affect any right of the Officer hereunder. This Paragraph 9 will apply in the event of any subsequent merger or consolidation or transfer of assets.

In the event of any merger, consolidation or sale of assets described above, nothing contained in this Agreement will detract from or otherwise limit the Officer’s right to or privilege of participation in any restricted stock plan, bonus or incentive plan, stock option or purchase plan, profit sharing, pension, group insurance, hospitalization or other compensation or benefit plan or arrangement which may be or become applicable to officers of the corporation resulting from such merger or consolidation or the corporation acquiring such assets of the Company.

In the event of any merger, consolidation or sale of assets described above, references to the Company in this Agreement shall, unless the context suggests otherwise, be deemed to include the entity resulting from such merger or consolidation or the acquirer of such assets of the Company.

10. No Mitigation. The Company agrees that the Officer is not required to seek other employment after a Qualifying Termination or to attempt in any way to reduce any amounts payable to the Officer by the Company under Paragraph 4 of this Agreement. Further, except as expressly provided in Paragraph 4(d), the amount of any payment or benefit provided for in this Agreement shall not be reduced by any compensation earned by the Officer as the result of employment by another employer, by retirement benefits, by offset against any amount claimed to be owed by the Officer to the Company, or otherwise.

11. Payments. All payments provided for in this Agreement shall be paid in cash in United States funds from the general funds of the Company and its subsidiaries drawn on the United States location of a bank and paid in bank or cashier’s check. The Company shall not be required to establish a special or separate fund or other segregation of assets to ensure such payments.

12. Tax Withholding; Section 409A.

(a) All payments made by the Company to the Officer or the Officer’s dependents, beneficiaries or estate will be subject to the withholding of such amounts relating to tax and/or other payroll deductions as may be required by law.

(b) It is intended that each installment of payment or benefits provided under this Agreement be treated as separate “payments” for purposes of Section 409A of the Code. The parties intend that the benefits and payments provided under this Agreement shall be exempt from, or comply with, the requirements of Section 409A of the Code. Notwithstanding the foregoing, the

Company shall in no event be obligated to indemnify the Officer for any taxes or interest that may be assessed by the IRS pursuant to Section 409A of the Code.

13. Arbitration.

(a) The Parties shall submit any disputes arising under this Agreement to an arbitration panel conducting a binding arbitration in Rogers, Connecticut or at such other location as may be agreeable to the parties, in accordance with the National Rules for the Resolution of Employment Disputes of the American Arbitration Association in effect on the date of such arbitration (the “Rules”), and judgment upon the award rendered by the arbitrator or arbitrators may be entered in any court having jurisdiction thereof; provided, however, that nothing herein shall impair the Company’s right to seek equitable relief for any breach or threatened breach under Paragraph 7 of this Agreement. The award of the arbitrators shall be final and shall be the sole and exclusive remedy between the Parties regarding any claims, counterclaims, issues or accountings presented to the arbitration panel.

(b) The Parties agree that the arbitration panel shall consist of one (1) person mutually acceptable to the Company and the Officer, provided that if the Parties cannot agree on an arbitrator within thirty (30) days of filing a notice of arbitration, the arbitrator shall be selected by the manager of the principal office of the American Arbitration Association in Hartford County in the State of Connecticut. Any action to enforce or vacate the arbitrator’s award shall be governed by the federal Arbitration Act, if applicable, and otherwise by applicable state law.

(c) If either Party pursues any claim, dispute or controversy against the other in a proceeding other than the arbitration provided for herein, the responding party shall be entitled to dismissal or injunctive relief regarding such action and recovery of all costs, losses and attorney’s fees related to such action.

(d) All of Officer’s reasonable costs and expenses incurred in connection with such arbitration shall be paid in full by the Company promptly on written demand from the Officer, including the arbitrators’ fees, administrative fees, travel expenses, out-of-pocket expenses such as copying and telephone, court costs, witness fees and attorneys’ fees; provided, however, the Company shall pay no more than $50,000 per year in attorneys’ fees unless a higher figure is awarded in the arbitration, in which event the Company shall pay the figure awarded in the arbitration.

(e) Reimbursement of reasonable costs and expenses under Paragraph 13(d) shall be administered consistent with the following additional requirements as set forth in Treas. Reg. § 1.409A-3(i)(1)(iv): (1) the Officer’s eligibility for benefits in one year will not affect the Officer’s eligibility for benefits in any other year; (2) any reimbursement of eligible expenses will be made on or before the last day of the year following the year in which the expense was incurred; and (3) the Officer’s right to benefits is not subject to liquidation or exchange for another benefit. Notwithstanding the foregoing, reimbursement for benefits under this Paragraph 13 shall commence no earlier than six months and a day after the Officer’s Separation from Service.

(f) The Officer acknowledges and expressly agrees that this arbitration provision constitutes a voluntary waiver of trial by jury in any action or proceeding to which the Officer or the Company may be parties arising out of or pertaining to this Agreement.

14. Assignment; Payment on Death.

(a) The provisions of this Agreement shall be binding upon and shall inure to the benefit of the Officer, the Officer’s executors, administrators, legal representatives and assigns and the Company and its successors.

(b) In the event that the Officer becomes entitled to payments under this Agreement and subsequently dies, all amounts payable to the Officer hereunder and not yet paid to the Officer at the time of the Officer’s death shall be paid to the Officer’s beneficiary. No right or interest to or in any payments shall be assignable by the Officer; provided, however, that this provision shall not preclude the Officer from designating one or more beneficiaries to receive any amount that may be payable after the Officer’s death and shall not preclude the legal representatives of the Officer’s estate from assigning any right hereunder to the person or persons entitled thereto under the Officer’s will or, in the case of intestacy, to the person or persons entitled thereto under the laws of intestacy applicable to the Officer’s estate. The term “beneficiary” as used in this Agreement shall mean the beneficiary or beneficiaries so designated by the Officer to receive such amount or, if no such beneficiary is in existence at the time of the Officer’s death, the legal representative of the Officer’s estate.

(c) No right, benefit or interest hereunder shall be subject to anticipation, alienation, sale, assignment, encumbrance, charge, pledge, hypothecation, or set-off in respect of any claim, debt or obligation, or to execution, attachment, levy or similar process, or assignment by operation of law. Any attempt, voluntary or involuntary, to effect any action specified in the immediately preceding sentence shall, to the full extent permitted by law, be null, void and of no effect.

15. Amendments and Waivers. Except as otherwise specified in this Agreement, this Agreement may be amended, and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Parties.

16. Integration. The terms of this Agreement shall supersede any prior agreements, understandings, arrangements or representations, oral or otherwise, expressed or implied, with respect to the subject matter hereof which have been made by either Party. By signing this Agreement, the Officer releases and discharges the Company from any and all obligations and liabilities heretofore or now existing under or by virtue of such prior agreements.

17. Notices. For the purpose of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given (a) on the date of delivery if delivered by hand, (b) on the date of transmission, if delivered by confirmed facsimile, (c) on the first business day following the date of deposit if delivered by guaranteed overnight delivery service, or (d) on the fourth business day following the date delivered or mailed by United States registered or certified mail, return receipt requested, postage prepaid, addressed as follows:

Rogers, CT 06263

or to such other address as either Party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

18. Severability. Any provision of this Agreement held to be unenforceable under applicable law will be enforced to the maximum extent possible, and the balance of this Agreement will remain in full force and effect.

19. Headings of No Effect. The paragraph headings contained in this Agreement are included solely for convenience or reference and shall not in any way affect the meaning or interpretation of any of the provisions of this Agreement.

20. Not an Employment Contract. This Agreement is not an employment contract and shall not give the Officer the right to continue in employment by Company or any of its subsidiaries for any period of time or from time to time. This Agreement shall not adversely affect the right of the Company or any of its subsidiaries to terminate the Officer’s employment with or without cause at any time.

21. Governing Law. This Agreement and its validity, interpretation, performance and enforcement shall be governed by the laws of the Commonwealth of Massachusetts (without reference to the choice of law principles thereof).

22. Counterparts. This Agreement may be executed in counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument.

3.This Agreement constitutes the complete understanding between the parties. Its purpose is to resolve any and all disputes or potential disputes without any party incurring additional time and expense. All agree that full settlement would best serve all interests.

4.______________ represents and warrants that he has the authority to enter into this Agreement, and that he has not assigned any claims being released under this Agreement to any person or entity.

5.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 contact or in tort.

6.By accepting the terms of this Agreement, ______________, for himself, his heirs, executors and administrators, releases and forever discharges the Released Parties of and from any and all liability in manner of suits, claims, charges or demands whatsoever, whether in law or in equity, under federal, state and municipal constitutions, statutes, charters, regulations and common law, including, but not limited to, the Family and Medical Leave Act under Federal and State laws, discrimination or retaliation claims under the Age Discrimination in Employment Act of 1967, as amended, 29 U.S.C. § 621 et seq.

This is a good and final release of all claims of every nature and kind whatsoever, and, by this Agreement, ______________ releases the Released Parties from all claims that are known

The term “Released Parties” used immediately above means Rogers, all of its related companies, subsidiaries and affiliates, their successors and assigns, and all of its and their present, former and future officers, representatives, agents or employees.

______________ acknowledges that certain states provide that a general release of claims does not extend to claims which the person executing the release does not know or suspect to exist in his favor at the time of executing the release which, if known by him, may have materially affected his entering the release of claims. Being aware that such statutory protection may be available to him, ______________ expressly, voluntarily and knowingly waives any arguable benefit or protection of any such statute in executing this Agreement, known or unknown.

(f)he understands that this Agreement will not become effective or enforceable unless and until he has not revoked it and the applicable revocation period set forth above has expired. The date on which the revocation period expires, if ______________ does not first revoke it, is the Effective Date of this Agreement; and

(g)he understands that nothing in this Agreement restricts his right to challenge the validity of the General Release of ADEA claims, to file a charge with the EEOC or to participate or cooperate in EEOC investigations or proceedings.

7.______________ agrees that by this Agreement, he is expressly waiving his right to bring or pursue any judicial action, any administrative agency or action, any contractual action, any statutory action or procedure or any action which he could have brought with respect to any matter arising from his employment with Rogers and separation therefrom with Rogers, provided, however, that this Agreement shall not preclude ______________ from seeking unemployment compensation or workers’ compensation benefits, nor shall it constitute a waiver with respect to any claims he may have for retirement benefits (e.g., 401(k) and pension benefits). ______________ also agrees that by entering into this Agreement, he is waiving any right he 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 his employment.

NON-COMPETE AGREEMENT

This Agreement is made on ______________________________(date), by and between Rogers Corporation (referred to as “Rogers”) and me, _____________________________, an employee, on behalf of ourselves, our heirs, successors and assigns. As used hereinafter, “Rogers” means Rogers Corporation and all subsidiaries and other companies owned or controlled by it as well as any predecessor company, and any company or business acquired by Rogers. This Agreement replaces in its entirety without any action by Rogers or me any existing Agreement entered into by Rogers and me relating to the same subject matter.

Rogers requires that I complete and execute this Agreement. But for my execution of this Agreement, I would not be eligible for the provisions of my Officer Special Severance Agreement signed by me on ________________.

Accordingly, Rogers and I agree as follows:

1. I have had a full and complete opportunity to discuss, consider and understand each provision of this Agreement, and agree that the terms of this Agreement are fair and reasonable.

2. I understand that Rogers invests substantial time, money and other resources training and developing its employees, and I agree that for a period of two (2) years following the termination of my employment for whatever reason, I will not solicit or recruit any of Rogers employees, whether directly or indirectly, to terminate their employment with Rogers.

3. Rogers develops and manufactures specialty polymer composite materials and components mainly for the imaging, communications, computer and peripheral, consumer products and transportation markets. It has consistently allocated considerable resources towards research and development activities with respect to its products, and it has devoted a substantial amount of time and effort and incurred significant costs in developing and maintaining its customers. I acknowledge that: (a) Rogers products are highly specialized items which have lengthy developmental periods; (b) the identity and particular needs of Rogers customers are not generally known in the industry; (c) Rogers has a proprietary interest in the identity of its customers and customer lists; and (d) the documents and information regarding Rogers products, processes, inventions, research, development, formulae, manufacturing and testing methods, business plans, customer or supplier identification, product cost and profit information, and the specialized requirements of Rogers customers are highly confidential and are regarded as trade secrets, commonly referred to at Rogers as “Proprietary Information”.

4. During the term of employment by Rogers, there may have been imparted to me, Proprietary Information of a business or technical nature. I understand I may have had access to Proprietary Information owned by or on behalf of Rogers and/or used in the course of its business. I will not directly or indirectly disclose any such Proprietary Information to any person or entity other than Rogers; use any such Proprietary Information in any way other than as authorized herein; or assist any person or entity other than Rogers to secure any benefit from such Proprietary Information, without the written consent of the Chief Executive Officer of Rogers.

5. All files, drawings, documents photographs, manuals, equipment, computer data or programs, electronic media, customer lists, other records and the like (and all copies thereof) which relate in any way to Rogers business (whether or not prepared, constructed, used or observed by me during my period of employment with Rogers) are and remain Rogers sole and exclusive property, and I agree to return said items (except for reprints or copies of published public information) to Rogers immediately upon the termination of my employment, and shall never deliver any such item (or any description thereof) to any person or entity, other than Rogers.

6. All ideas, processes, discoveries, inventions, computer programs and software, improvements and suggestions, whether they be patentable or not, made, devised, conceived, developed or perfected by me alone or with any other person or persons during the term of employment by Rogers or within six (6) months thereafter, which are in any way reasonably related to the products, apparatus, components thereof, or modified for use, developed, under development or pertaining to the business (including research and development) of Rogers (otherwise referred to as “Developments”), will be the sole and exclusive property of Rogers, and I agree to sell, transfer, and assign to Rogers, its successors and assigns, my entire right, title and interest in and to all such Developments.

7. In order to protect Rogers against disclosure of any such Proprietary Information, I agree, as further consideration for my Officer Special Severance Agreement, that for a period of two years after termination of employment with Rogers (for whatever reason), I will not, without first obtaining written permission from the Chief Executive Officer of Rogers, engage in, render services, either as an employee, consultant or independent contractor, or become associated in any way, either directly or indirectly, in the research, development, manufacture, use or sale of any product which is the same as, similar to or is competitive with any product, development or research activity of Rogers with respect to which at any time during the two years preceding termination of employment with Rogers, or a company acquired by Rogers,

my work has been directly or indirectly concerned, or with respect to which I have acquired knowledge of any Proprietary Information. Rogers will enforce the provisions of this non-compete paragraph only for certain technical, sales, marketing or management employees.

8. Before I accept an offer to become associated with an organization which may have a product which may violate this agreement as described above, I agree to provide Rogers with the following information: the name of the company, division or product line, job duties and title. Upon receiving sufficient information to make a determination, Rogers may release me or enforce the terms of this agreement.

9. I acknowledge that I am free to enter into this Agreement without violating any obligations to any other person or company and that I will not make any unauthorized use of the Proprietary Information. I agree that following termination of my employment with Rogers, I will make the terms of this Agreement known to any subsequent employer if such employer is engaged in any business similar to or competitive with any product of Rogers.

10. If any provision of this Agreement is found to be invalid or unenforceable, it shall not affect the remaining provisions of this Agreement. Further, a court shall have the authority to reform and rewrite the “invalid or unenforceable” provision, so it will be valid and enforceable.

11. Any prior service that I have had with a company which is acquired by, merged with, or otherwise becomes affiliated with Rogers through joint venture or other corporate transaction will be deemed to be continuous employment by Rogers for all purposes of this Agreement.

12. In the event that I am assigned by Rogers to work for any other company or organization which is a subsidiary or joint venture of or is otherwise affiliated with, Rogers or which is a successor company by way of acquisition, merger or other corporate transaction, such employment will be deemed to be continuous employment by Rogers for the purpose of this Agreement.

13. Rogers’ failure to enforce the terms of another Agreement similar to this with another employee, shall not constitute a waiver of any term or provision in this Agreement.

14. This Agreement shall be subject to the laws of the State of Connecticut and any dispute arising herein will be heard in the appropriate state or federal court, as applicable, within this jurisdiction.

15. I acknowledge that full compliance with the terms of this Agreement is necessary to protect the business and goodwill of Rogers and that a breach of this Agreement will irreparably and continually harm Rogers, for which money damages may not be adequate. Consequently, I understand that, in the event I breach or threaten to breach any of these covenants, Rogers shall be entitled to both (a) a preliminary or permanent injunction in order to prevent the continuation of such harm and (b) money damages insofar as they can be determined. Nothing in this Agreement, however, will be construed to prohibit Rogers from also pursuing any other remedy, Rogers and I having agreed that all remedies are cumulative.

16. No alteration or modification to any of the provisions of this Agreement shall be valid unless made in writing and signed by both Rogers and me.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

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

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

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

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

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

(Dollars in thousands)	Carrying amount as of June 30, 2015			Level 1	Level 2			Level 3
Foreign currency contracts	$	235		—	$	235		—
Copper derivative contracts	436			—	436			—

(Dollars in thousands)	Carrying amount as of December 31, 2014			Level 1	Level 2			Level 3
Foreign currency contracts	$	(18	)	—	$	(18	)	—
Copper derivative contracts	355			—	355			—

Derivatives Contracts

We are exposed to certain risks related to our ongoing business operations. The primary risks being managed through the use of derivative instruments are foreign currency exchange rate risk, commodity pricing risk (primarily related to copper) and interest rate risk.   

• 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.

We do not use derivative financial instruments for trading or speculative purposes.

For further discussion on our derivative contracts, see Note 3 - "Hedging Transactions and Derivative Financial Instruments" below.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

Our effective income tax rate was 29.0% and 33.9% in the second quarter of 2015 and 2014, respectively. Our effective income tax rate was 30.3% and 31.1% for the six months ended June 30, 2015 and 2014, respectively. In the second quarter of 2015, our income tax rate was unfavorably impacted by a discrete tax expense of approximately $0.4 million due to the redemption of corporate owned life insurance policies, and was favorably impacted by a discrete tax benefit of approximately $1.6 million due to a change in our state tax rate as a result of a legal reorganization undertaken during the quarter. In both the second quarter of 2015, as well as the second quarter of 2014, our income tax rate benefited from favorable tax rates on certain foreign business activity as compared to our statutory tax rate of 35%.

We are subject to income taxes in the United States and in numerous foreign jurisdictions.  No provision is made for U.S. income taxes on the undistributed earnings of substantially all of our wholly-owned foreign subsidiaries because such earnings are indefinitely reinvested in those companies. If circumstances change and it becomes apparent that some or all of the undistributed earnings of our wholly-owned foreign subsidiaries will not be indefinitely reinvested, a provision for the tax consequences, if any, will be recorded in the period in which the circumstances change.

Our accounting policy is to account for interest expense and penalties related to uncertain tax positions as income tax expense.  As of June 30, 2015, we have approximately $1.2 million of accrued interest related to uncertain tax positions included in the $12.4 million of unrecognized tax benefits, $12.3 million of which, if recognized, would impact the effective tax rate.

We are subject to taxation in the U.S. and various state and foreign jurisdictions. Our tax years from 2011 through 2014 are subject to examination by these various tax authorities. With few exceptions, we are no longer subject to U.S. federal, state, local and foreign examinations by tax authorities for years before 2011.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued a new standard to achieve a consistent application of revenue recognition within the U.S., 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 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. On July 9, 2015, the FASB agreed to delay the effective date by one year. In accordance with the agreed upon delay, the new standard is effective for us beginning in the first quarter of 2018. Early adoption is permitted, but not before the original effective date of the standard. The new standard is required to be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. We have not yet selected a transition method nor have we determined the impact of the new standard on our consolidated condensed financial statements.

Segment Reporting [Abstract]

Segment Information

Segment Information

Our reporting structure is comprised of the following operating segments: Advanced Connectivity Solutions (ACS), Elastomeric Material Solutions (EMS), Power Electronics Solutions (PES) and the Other segment. We believe this structure aligns our external reporting presentation with how we currently manage and view our business internally. In the second quarter of 2015, we concluded that we needed to update two of our operating segment names to better align the business product portfolio offerings to the market. Therefore, Advanced Connectivity Solutions replaces the name of Printed Circuit Materials, and Elastomeric Material Solutions replaces the name of High Performance Foams. There were no changes to the composition of these two operating segments. The Power Electronics Solutions and Other segment names remain unchanged.

We completed the acquisition of Arlon on January 22, 2015. As part of the integration process, Arlon operations related to circuit materials and silicones were included in our ACS and EMS segments, respectively. The Other segment includes the Arlon business that manufactures specialty polyimide, epoxy-based laminates and bonding materials.

As a result of the acquisition, we significantly increased our asset holdings. The following table sets forth the total assets allocated to each segment:

Joint Ventures

Joint Ventures

As of June 30, 2015, we had two joint ventures, each 50% owned, which were accounted for under the equity method of accounting.

Joint Venture	Location	Reportable 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 $0.4 million and $1.3 million for the three and six month periods ended June 30, 2015, respectively. We recognized equity income related to the joint ventures of $1.1 million and $2.0 million for the three and six month periods ended June 30, 2014, respectively. These amounts are included in the condensed consolidated statements of income.

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

(Dollars in thousands)	Three Months Ended				Six Months Ended
	June 30, 2015		June 30, 2014		June 30, 2015		June 30, 2014

Acquisition

Acquisition

On January 22, 2015, we completed the previously announced acquisition of Arlon and its subsidiaries, other than Arlon India (Pvt) Limited (collectively, “Arlon”), pursuant to the terms of the Stock Purchase Agreement, dated December 18, 2014, by and among the Company, Handy & Harman Group, Ltd. (“H&H Group”) and its subsidiary Bairnco Corporation (“Bairnco”) (as amended, the “Purchase Agreement”).

Pursuant to the terms of the Purchase Agreement, we acquired Arlon and assumed certain liabilities related to the acquisition for an aggregate purchase price of approximately $157 million. The purchase price is subject to final post-closing adjustments under the terms of the Purchase Agreement.

We used borrowings of $125.0 million under our bank credit facility in addition to cash on hand, to fund the acquisition.

Arlon manufactures high performance materials for the printed circuit board industry and silicone rubber-based materials. The acquisition of Arlon and its integration into our operating segments is expected to provide increased scale and complementary product offerings, allowing us to enhance our ability to support our customers.

The acquisition has been accounted for in accordance with applicable purchase accounting guidance. The following table represents the preliminary fair market values assigned to the acquired assets and liabilities in the transaction. On a preliminary basis, we recorded goodwill, primarily related to the expected synergies from combining operations and the value of the existing workforce. We also recorded intangible assets related to trademarks, technology and customer relationships. As of the filing date of this Form 10-Q, the process of valuing the net assets of the business is substantially complete. These values may be updated until certain items are settled in the final agreement.

Fair value of net assets acquired	$	158,548

The intangible assets consist of developed technology valued at $15.8 million, customer relationships valued at $32.7 million and trademarks valued at $1.6 million. The fair value of acquired identified intangible assets was determined by applying the income approach, using several significant unobservable inputs for projected cash flows and a discount rate. These inputs are considered Level 3 under the fair value measurements and disclosure guidance.

The weighted average amortization period for the intangible asset classes are 5.7 years for developed technology, 6.0 years for customer relationships and 3.2 years for trademarks, resulting in amortization expenses ranging from $1.8 million to $5.8 million annually. The estimated annual future amortization expense is $3.2 million for the remainder of 2015, and $5.8 million for each of the years ending 2016, 2017, 2018 and 2019.

During the first six months of 2015, we incurred transaction costs of $1.5 million, which were recorded within selling and administrative expenses on the condensed consolidated statement of income.

The results of Arlon have been included in our consolidated financial statements only for the period subsequent to the completion of our acquisition on January 22, 2015. Arlon's revenues for the three and six month periods ended June 30, 2015 totaled $25.4 million and $45.6 million, respectively.

The following unaudited pro forma financial information presents the combined results of operations of Rogers and Arlon for the three and six months ended June 30, 2014, as if the acquisition had occurred on January 1, 2014. The unaudited pro forma financial information is not intended to represent or be indicative of our consolidated results of operations or financial position that would have been reported had the Arlon acquisition been completed as of January 1, 2014 and should not be taken as indicative of our future consolidated results of operations or financial position.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued a new standard to achieve a consistent application of revenue recognition within the U.S., 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 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. On July 9, 2015, the FASB agreed to delay the effective date by one year. In accordance with the agreed upon delay, the new standard is effective for us beginning in the first quarter of 2018. Early adoption is permitted, but not before the original effective date of the standard. The new standard is required to be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. We have not yet selected a transition method nor have we determined the impact of the new standard on our consolidated condensed financial statements.

Debt Disclosure [Abstract]

Debt

Debt

On June 18, 2015, we entered into a secured five year credit agreement (the "Amended Credit Agreement"). The Amended Credit Agreement amends and restates the credit agreement signed between the Company and the same banks on July 13, 2011 and increased our borrowing capacity from $265.0 million to $350.0 million, with an additional $50.0 million expansion option.

The Amended Credit Agreement provides (1) a $55.0 million term loan; (2) up to $295.0 million of revolving loans, with sub-limits for multicurrency borrowings, letters of credit and swing-line notes; and (3) a $50.0 million expansion 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 Amended Credit Agreement).  

Borrowings under the Amended Credit Agreement bear interest based on one of two options. 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 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 Amended Credit Agreement, the Company is required to pay a quarterly fee of 0.20% to 0.30% (based upon our leverage ratio) of the unused amount of the lenders’ commitments under the Amended Credit Agreement.

The Amended Credit Agreement contains customary representations, warranties, covenants, mandatory prepayments and events of default under which the Company's payment obligations may be accelerated. The financial covenants include requirements to maintain (1) a leverage ratio of no more than 3.25 to 1.00, subject to a one-time 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 ("ICR") of no less than 3.00 to 1.00. The ICR is the ratio determined as of the end of each of its fiscal quarters ending on and after June 30, 2015, of (i) Consolidated Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) (as defined in the Amended Credit Agreement) minus the unfinanced portion of Consolidated Capital Expenditures to (ii) Consolidated Interest Expense paid in cash, in each case for the period of four consecutive fiscal quarters ending with the end of such fiscal quarter, all calculated for the Borrower and its subsidiaries on a consolidated basis.

As of June 30, 2015, we were in compliance with all of the financial covenants in the Amended Credit Agreement, as we achieved actual ratios of approximately 1.34 to 1.00 on the leverage ratio and 30.68 to 1.00 on the ICR.

The Amended Credit Agreement requires the mandatory quarterly repayment of principal on amounts borrowed under such term loan. Payments will commence on September 30, 2015, and are scheduled to be completed on June 30, 2020. The aggregate mandatory principal payments due are as follows:

2015	$1.4	million
2016	$3.4	million
2017	$4.1	million
2018	$4.8	million
2019	$5.5	million
2020	$160.8	million

All obligations under the Amended Credit Agreement are guaranteed by each of the Corporation’s existing and future material domestic subsidiaries, as defined in the Amended Credit Agreement (the “Guarantors”). The obligations are also secured by a Second Amended and Restated Pledge and Security Agreement, dated as of June 18, 2015, entered into by the Company 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 Company and the Guarantors.

All amounts borrowed or outstanding under the Amended Credit Agreement, with the exception of amounts borrowed under the term loan which are subject to quarterly principal payments, are due and mature on June 18, 2020, unless the commitments are terminated earlier either at the request of the Company or if certain events of default occur. At June 30, 2015, the Company had outstanding debt of $180.0 million under the Amended Credit Agreement which included $55.0 million borrowed under the term loan and $125.0 million borrowed under the revolving line of credit.

In addition, as of June 30, 2015 we had a $1.4 million standby letter of credit (LOC) to guarantee Rogers workers compensation plans that were backed by the Amended Credit Agreement. No amounts were drawn on the LOC as of June 30, 2015 or December 31, 2014.

The Amended Credit Agreement is secured by many of the assets of Rogers, including but not limited to, receivables, equipment, intellectual property, inventory, and stock in certain subsidiaries.

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.  

Before entering into the Amended Credit Agreement, we had $0.5 million of remaining capitalized costs from the previous credit agreements. These costs will continue to be amortized over the life of the Amended Credit Agreement. In the second quarter of 2015, we capitalized an additional $1.6 million in connection with the Amended Credit Agreement. These costs will be amortized over the life of the Amended Credit Agreement, which will terminate in June 2020. 

We incurred amortization expense of $0.1 million in each of the second quarters of 2015 and 2014, and amortization expense of $0.2 million in each of the first six months of 2015 and 2014. At June 30, 2015, we have approximately $2.1 million of credit facility costs remaining to be amortized.

We borrowed $125.0 million under the line of credit in the first quarter of 2015 to fund the acquisition of Arlon. During the first six months of 2015 and 2014, we made principal payments of $5.0 million and $7.5 million, respectively, on the outstanding debt. The principal amount of this debt has been transferred to the new revolving credit line created in June of 2015. We are obligated to pay $2.8 million on this debt obligation in the next 12 months under the term loan.

We incurred interest expense on our outstanding debt of $1.1 million and $1.9 million for the three and six month periods ended June 30, 2015, respectively, and $0.5 million and $1.0 million for the three and six month periods ended June 30, 2014, respectively.

We incurred an unused commitment fee of $0.1 million and $0.1 million for the three and six month periods ended June 30, 2015 and $0.1 million and $0.2 million for the three and six month periods ended June 30, 2014, respectively. In July 2012, we entered into an interest rate swap to hedge the variable interest rate on our term loan debt. As of June 30, 2015, the remaining notional amount of the interest rate swap covers $32.5 million of our term loan debt. At June 30, 2015, our outstanding debt balance is comprised of a term loan of $55.0 million and $125.0 million borrowed on the revolving line of credit. At June 30, 2015, the rate charged on this debt is the 1 month LIBOR at 0.1875% plus a spread of 1.625%.

Pursuant to the Amended Credit Agreement, we cannot make a cash dividend payment if (i) a default or event of default has occurred and is continuing or will result from the cash dividend payment or (ii) if the aggregate amount of all cash dividend payments and other such restricted payments (as defined in the Amended Credit Agreement) that are otherwise not permitted during any fiscal year exceeds $10.0 million; provided that, if at the time of and immediately after giving effect (including on a pro forma basis) thereto, the Leverage Ratio (as defined in the Amended Credit Agreement) is less than or equal to 2.00 to 1.00, such dollar limitation would not apply.

Capital Lease

During the first quarter of 2011, we recorded a capital lease obligation related to the acquisition of Curamik Electronics GmbH ("Curamik") for its primary 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 June 30, 2015 is $6.1 million. Depreciation expense related to the capital lease was $0.1 million in each of the three month periods ended June 30, 2015 and 2014 and $0.2 million in the six month periods ending June 30, 2015 and 2014. Accumulated depreciation at June 30, 2015 and December 31, 2014 was $1.8 million and $1.6 million, respectively. These expenses are included as depreciation expense in cost of sales on our condensed consolidated statements of income.

We also incurred interest expense on the capital lease of $0.1 million and $0.2 million for the three and six month periods ended June 30, 2015, respectively, and $0.1 million and $0.3 million for the three and six month periods ended June 30, 2014, respectively. Interest expense related to the debt recorded on the capital lease is included in interest expense on the condensed consolidated statements of income.

We guarantee an interest rate swap related to our lease of the manufacturing facility in Eschenbach, Germany. The swap is in a liability position with the bank at June 30, 2015, and has a fair value of $0.3 million. We have concluded that default by the lessor is not probable during the term of the swap, and we have chosen not to exercise the option to buyout the lease during the leasing period; therefore, the guarantee has no value. For more information about the manufacturing facility, see Capital Lease section below.

Share-based Compensation [Abstract]

Stock-Based Compensation

Stock-Based Compensation

Equity Compensation Awards

Stock Options

Stock options have been granted under various equity compensation plans. While we may grant options to employees that become exercisable at different times or within different periods, we have generally granted options to employees that vest and become exercisable in one-third increments on the second, third and fourth anniversaries of the grant dates. The maximum contractual term for all options is normally ten years.

We use 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.

In most cases, we recognize expense using the straight-line method for stock option grants. The amount of stock-based compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option. We currently expect, based on an analysis of our historical forfeitures, an annual forfeiture rate of approximately 3% and applied that rate to the grants issued. This assumption is reviewed periodically and the rate is adjusted as necessary based on these reviews. Ultimately, the actual expense recognized over the vesting period will only be for those options that vest.

During the three and six month periods ended June 30, 2015 we recognized approximately $0.1 million and $0.1 million of stock option compensation expense, respectively. During the three and six month periods ended June 30, 2014 we recognized approximately $0.1 million and $0.2 million of stock option compensation expense, respectively.

A summary of the activity under our stock option plans as of June 30, 2015 and changes during the three and six month periods 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 March 31, 2015	251,400		$	41.06	3.7	$	10,344,139
Options exercised	(26,562	)	$	46.09
Options forfeited	(600	)	$	34.83
Options outstanding at June 30, 2015	224,238		$	40.49	3.5	5,752,806
Options exercisable at June 30, 2015	223,427		$	39.98	3.2	5,845,097
Options vested or expected to vest at June 30, 2015*	224,214		$	40.47	3.5	5,755,574

* In addition to the vested options, we expect a portion of the unvested options to vest at some point in the future. Options expected to vest are calculated by applying an estimated forfeiture rate to the unvested options.

	Options Outstanding		Weighted- Average Exercise Price Per Share
Options outstanding at December 31, 2014	393,347		$	40.72
Options exercised	(167,659	)	$	40.91
Options forfeited	(1,450	)	$	39.62
Options outstanding at June 30, 2015	224,238

During the six month period ended June 30, 2015, 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 $6.4 million, and the total amount of cash received from the exercise of these options was $6.2 million.

Performance-Based Restricted Stock

In 2006, we began granting performance-based restricted stock awards. We currently have awards from 2013, 2014 and 2015 outstanding. These awards cliff vest at the end of the three year measurement period, except for the 2015 grants to those individuals who are retirement eligible during the grant period. These individuals may receive a pro-rata payout based on the actual retirement date if it occurs during the vesting period. Participants are eligible to be awarded shares ranging from 0% to 200% of the original award amount, based on certain defined measurement criteria. Compensation expense is recognized using the straight-line method over the vesting period.  

All outstanding awards have two measurement criteria on which the final payout of each award is based - (i) the three year return on invested capital (ROIC) compared to that of a specified group of peer companies, and (ii) the three year total shareholder return (TSR) on the performance of our common stock as compared to that of a specified group of peer companies. In accordance with the applicable accounting literature, the ROIC portion of each award is considered a performance condition. As such, the fair value of each award is determined based on the market value of the underlying stock price at the grant date with cumulative compensation expense recognized to date being increased or decreased based on changes in the forecasted pay out percentage at the end of each reporting period. The TSR portion of the award is considered a market condition. As such, the fair value of this award 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 with no changes for the final projected payout of the award.

The amount of performance-based restricted stock compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” and represents only the unvested portion of the surrendered award. We currently expect, based on an analysis of our historical forfeitures, an annual forfeiture rate of approximately 7% and applied that rate to the grants issued. This assumption will be reviewed periodically and the rate will be adjusted as necessary based on these reviews. Ultimately, the actual expense recognized over the vesting period will only be for those awards that vest.

Below are the assumptions used in the Monte Carlo calculation:

	June 30, 2015	June 30, 2014
Expected volatility	28.2%	33.7%
Expected term (in years)	3.0	3.0
Risk-free interest rate	0.96%	0.67%
Expected dividend yield	—	—

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

Expected term – We use the vesting period of the award to determine the expected term assumption for the Monte Carlo simulation valuation model.

Risk-free interest rate – We use an implied "spot rate" yield on U.S. Treasury Constant Maturity rates as of the grant date for our assumption of the risk-free interest rate.

Expected dividend yield – We do not currently pay dividends on our common stock; therefore, a dividend yield of 0% was used in the Monte Carlo simulation valuation model.

Actual performance during the relevant period for the 2012 award, which vested as of December 31, 2014, met the target performance criteria and shares were paid out at 120.0% of target during the second quarter of 2015.

	Performance-Based Restricted Stock Awards
Non-vested awards outstanding at December 31, 2014	92,437
Awards granted	50,798
Stock issued	(20,910	)
Awards forfeited	(8,605	)
Non-vested awards outstanding at June 30, 2015	113,720

During the three and six months periods ended June 30, 2015, we recognized compensation expense for performance-based restricted stock awards of approximately $1.2 million and $1.6 million, respectively. During the three and six month periods ended June 30, 2014, we recognized expense for performance-based restricted stock awards of approximately $0.7 million and $1.3 million, respectively.

Time-Based Restricted Stock

In 2011, we began granting time-based restricted stock awards to certain key executives and other key members of the Company’s management team. We currently have grants from 2011, 2012, 2013, 2014 and 2015 outstanding. The 2011 and 2012 grants cliff vest at the end of the four and three year vesting periods, respectively. The 2013, 2014 and 2015 grants typically vest on the first, second and third anniversaries of the original grant date. We do occasionally grant awards that cliff vest after 4 years. We recognize compensation expense on all of these awards on a straight-line basis over 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.

The amount of time-based restricted stock compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” and represents only the unvested portion of the surrendered award. We currently expect, based on an analysis of our historical forfeitures, an annual forfeiture rate of approximately 7% and applied that rate to the grants issued. This assumption will be reviewed periodically and the rate will be adjusted as necessary based on these reviews. Ultimately, the actual expense recognized over the vesting period will only be for those awards that vest.

	Time-Based Restricted Stock Awards
Non-vested awards outstanding at December 31, 2014	238,386
Awards granted	65,285
Stock issued	(69,352	)
Awards forfeited	(4,969	)
Non-vested awards outstanding at June 30, 2015	229,350

During the three and six month periods ended June 30, 2015, we recognized compensation expense for time-based restricted stock awards of approximately $1.3 million and $2.4 million, respectively. During the three and six month periods ended June 30, 2014, we recognized compensation expense for time-based restricted stock awards of approximately $1.1 million and $2.1 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’ 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.

	Deferred Stock Units
Awards outstanding at December 31, 2014	30,150
Awards granted	9,100
Stock issued	(15,400	)
Awards outstanding at June 30, 2015	23,850

For both the three and six month periods ended June 30, 2015 and 2014 we recognized compensation expense for deferred stock units of $0.7 million and $0.8 million, respectively.

Employee Stock Purchase Plan

We have an employee stock purchase plan (ESPP) that allows eligible employees to purchase, through payroll deductions, shares of our common 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 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 amount 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 for each of the three month periods ended June 30, 2015 and 2014, and approximately $0.2 million of compensation expense associated with each of the six month periods ended June 30, 2015 and 2014.

In the first quarter of 2015, as part of the acquisition of Arlon, we acquired the Hourly Employees Pension Plan of Arlon, LLC, Microwave Materials and Silicone Technologies Divisions, Bear, Delaware. This plan covers Arlon union employees and was frozen to new participants and accumulating benefits in 2006. As of the acquisition date, January 22, 2015, the funded status of the plan was a liability of approximately $2.0 million. We have recorded this as part of our long term pension liability within our condensed consolidated statements of financial position.

In the first quarter of 2014, we made a one-time cash payment to a former employee of $0.8 million in accordance with the provisions of his retirement contract related to his participation in the Company's Pension Restoration Plan. This payment resulted in a settlement charge of approximately $0.1 million, which was recognized in the first quarter of 2014.

Employer Contributions

In the second quarters of 2015 and 2014, we made voluntary contributions of $6.5 million and $6.5 million, respectively to our qualified defined benefit pension plans. These are the only amounts contributed in the first six months of 2015 and 2014.

We did not make any contributions to our non-qualified defined benefit pension plan for the six months ended June 30, 2015 or the three months ended June 30, 2014. We made $0.8 million in contributions to our non-qualified defined benefit pension plan for the quarter ended March 31, 2014.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

We are currently engaged in the following environmental and legal proceedings:

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 June 30, 2015, 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 on for the indefinite future. No time frame for completion can be estimated at the present time.

PCB Contamination

We have been working with the Connecticut Department of Energy and Environmental Protection (CT DEEP) and the United States Environmental Protection Agency (EPA), 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, and this initial issue was remediated in 2000. 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. Additional PCB contamination at this facility was found in the original buildings, courtyards and surrounding areas including an on-site pond. Remediation activities of the affected building materials and courtyards were completed in 2014 at a total cost of $0.5 million. Remediation costs related to the soil contamination and the on-site pond are ongoing and expected to approximate $0.7 million. The soil contamination remediation is completed and we currently have a reserve of $0.2 million for the pond remediation recorded in our consolidated statements of financial position. We believe this reserve will be adequate to cover the remaining remediation work related to the soil and pond contamination based on the information known at this time. However, if additional contamination is found, the cost of the remaining remediation may increase.

Overall, we have spent approximately $2.4 million in remediation and monitoring costs related to these various PCB contamination issues. 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.

Asbestos Litigation

A significant number of asbestos-related product liability claims have been brought against numerous United States industrial companies where the third-party plaintiffs allege personal injury from exposure to asbestos-containing products. We have been named, along with hundreds of other companies, as a defendant in some of these claims. In virtually all of these claims filed against us, the plaintiffs are seeking unspecified damages, or, if an amount is specified, such amount merely represents a jurisdictional amount. However, occasionally specific damages are alleged and in such situations, plaintiffs’ lawyers often sue dozens of defendants, frequently without factual basis or support. As a result, even when a specific amount of damages is alleged, such action can be arbitrary, both as to the amount being sought and the defendant being charged with such damages.

We did not mine, mill, manufacture or market asbestos; rather we made a limited number of products which contained encapsulated asbestos. Such products were provided to industrial users. We stopped manufacturing these products in the late 1980s.

• Claims

We have been named in asbestos litigation primarily in Illinois, Pennsylvania and Mississippi. As of June 30, 2015, there were 444 pending claims compared to 438 pending claims at December 31, 2014. The number of pending claims at a particular time can fluctuate significantly from period to period depending on how successful we have been in getting these cases dismissed or settled. Some jurisdictions prohibit specifying alleged damages in personal injury tort cases such as these, other than a minimum jurisdictional amount which may be required for such reasons as allowing the case to be litigated in a jury trial (which the plaintiffs believe will be more favorable to them than if heard only before a judge) or allowing the case to be litigated in federal court. This is in contrast to commercial litigation, in which specific alleged damage claims are often permitted. The prohibition on specifying alleged damages sometimes applies not only to the suit when filed but also during the trial – in some jurisdictions the plaintiff is not actually permitted to specify to the jury during the course of the trial the amount of alleged damages the plaintiff is claiming. Further, in those jurisdictions in which plaintiffs are permitted to claim specific alleged damages, many plaintiffs nonetheless still choose not to do so. In those cases in which plaintiffs are permitted to and choose to assert specific dollar amounts in their complaints, we believe the amounts claimed are typically not meaningful as an indicator of a company’s potential liability. This is because (1) the amounts claimed may bear no relation to the level of the plaintiff’s alleged injury and are often used as part of the plaintiff’s litigation strategy, (2) the complaints typically assert claims against numerous defendants, and often the alleged damages are not allocated against specific defendants, but rather the broad claim is made against all of the defendants as a group, making it impossible for a particular defendant to quantify the alleged damages that are being specifically claimed against it and therefore its potential liability, and (3) many cases are brought on behalf of plaintiffs who have not suffered any medical injury, and ultimately are resolved without any payment or payment of a small fraction of the damages initially claimed.

We believe the rate at which plaintiffs filed asbestos-related suits against us increased in 2001, 2002, 2003 and 2004 because of increased activity on the part of plaintiffs to identify those companies that sold asbestos-containing products, but which did not directly mine, mill or market asbestos. A significant increase in the volume of asbestos-related bodily injury cases arose in Mississippi in 2002. This increase in the volume of claims in Mississippi was apparently due to the passage of tort reform legislation (applicable to asbestos-related injuries), which became effective on September 1, 2003 and which resulted in a higher than average number of claims being filed in Mississippi by plaintiffs seeking to ensure their claims would be governed by the law in effect prior to the passage of tort reform. The number of asbestos related suits filed against us decreased slightly in 2005 and 2006, but increased slightly in 2007, declined in 2008 and increased again in 2009 and 2010. The number of lawsuits filed against us in 2011, 2012, 2013, 2014 and the first six months of 2015 (annualized) was significantly higher than in 2010. These new lawsuits are reflected in the National Economic Research Associates, Inc. ("NERA") and Marsh USA, Inc. ("Marsh") reports. See "Impact on Financials Statements" section below.

• Defenses

In many cases, plaintiffs are unable to demonstrate that they have suffered any compensable loss as a result of exposure to our asbestos-containing products. We believe that the trend will continue and that a majority of the claimants in pending cases will not be able to demonstrate exposure or loss. This belief is based in large part on the limited number of asbestos-related products manufactured and sold by us and the fact that the asbestos was encapsulated in such products. In addition, even at sites where the presence of an alleged injured party can be verified during the same period those products were used, our liability cannot be presumed because even if an individual contracted an asbestos-related disease, not everyone who was employed at a site was exposed to the asbestos containing products that we manufactured. Based on these and other factors, we have and will continue to vigorously defend ourselves in asbestos-related matters.

• Dismissals and Settlements

Cases involving us typically name 50-300 defendants, although some cases have had as few as one (1) and as many as 833 defendants. We have obtained the dismissal of many of these claims. For the six months ended June 30, 2015, 45 claims were dismissed and one claim was settled. For the year ended December 31, 2014, 104 claims were dismissed and 13 were settled. The majority of costs have been paid by our insurance carriers, including the costs associated with the small number of cases that have been settled. We paid $0.5 million on settlements for the six months ended June 30, 2015, compared to $3.2 million for the year ended 2014. Although these figures provide some insight into our experience with asbestos litigation, no guarantee can be made as to the dismissal and settlement rates that we will experience in the future.

Settlements are made without any admission of liability. Settlement amounts may vary depending upon a number of factors, including the jurisdiction where the action was brought, the nature and extent of the disease alleged and the associated medical evidence, the age and occupation of the claimant, the existence or absence of other possible causes of the alleged illness of the alleged injured party and the availability of legal defenses, as well as whether the action is brought alone or as part of a group of claimants. To date, we have been successful in obtaining dismissals for many of the claims and have settled only a limited number. Most of the settled claims were settled for nominal amounts, and the majority of such payments have been borne by our insurance carriers. In addition, to date, we have not been required to pay any punitive damage awards.

• Potential Liability

NERA has historically been engaged to assist us in projecting our future asbestos-related liabilities and defense costs with regard to pending claims and future claims. Projecting future asbestos costs is subject to numerous variables that are extremely difficult to predict, including the number of claims that might be received, the type and severity of the disease alleged by each claimant, the long latency period associated with asbestos exposure, dismissal rates, costs of medical treatment, the financial resources of other companies that are co-defendants in claims, uncertainties surrounding the litigation process from jurisdiction to jurisdiction and from case to case and the impact of potential changes in legislative or judicial standards, including potential tort reform. Furthermore, any predictions with respect to these variables are subject to even greater uncertainty as the projection period lengthens. In light of these inherent uncertainties, the  variability of our claims history and consultations with NERA, we currently believe that ten years is the most reasonable period for recognizing a reserve for future costs, and that costs that might be incurred after that period are not reasonably estimable at this time. As a result, we also believe that our ultimate asbestos-related contingent liability (i.e., our indemnity or other claim disposition costs plus related legal fees) cannot be estimated with reasonable certainty. (See "Impact on Financials Statements" section below for further discussion.)

• Insurance Coverage

Our applicable insurance policies generally provide coverage for asbestos liability costs, including coverage for both indemnity and defense costs. Following the initiation of asbestos litigation, an effort was made to identify all of our primary, umbrella and excess level insurance carriers that provided applicable coverage beginning in the 1950s through the mid-1980s. We located primary policies for all such years except for the early 1960s. With respect to this period, we entered into an arrangement with ACE Property & Casualty Insurance Company in 2005, pursuant to which we and they share in asbestos liabilities allocable to such period. We have located umbrella or excess layer policies for all such years except for the period from May 18, 1961 to May 18, 1964. We believe that a policy was purchased from Continental Casualty Company covering this period based upon documents we have found, but the insurer has denied coverage. This policy has not yet been triggered.

Where appropriate, carriers were put on notice of the litigation. Marsh has historically been engaged to work with us to project our insurance coverage for asbestos-related claims. Marsh’s conclusions are based primarily on a review of our coverage history, application of reasonable assumptions on the allocation of coverage consistent with certain industry practices, an assessment of the creditworthiness of the insurance carriers, analysis of applicable deductibles, retentions and policy limits, the experience of NERA and a review of NERA’s reports.

• Cost Sharing Agreement

To date, our insurance carriers have paid for substantially all of the settlement and defense costs associated with our asbestos-related claims. The current cost sharing agreement between us and such insurance carriers is primarily designed to facilitate the ongoing administration and payment of such claims by the carriers until the applicable insurance coverage is exhausted. This agreement, which replaced an older agreement that had expired, can be terminated by election of any party thereto after January 25, 2015. Absent any such election, the agreement will continue until a party elects to terminate it. As of the report filing date for this report, the agreement has not been terminated.

In 2014, the primary layer insurance policies providing coverage for the January 1, 1966 to January 1, 1967 period exhausted. The cost sharing agreement contemplates that any excess carrier over exhausted primary layer carriers will become a party to the cost sharing agreement, replacing the coverage provided by the exhausted primary policies if the carrier providing such excess coverage is not already a party to the cost sharing agreement. The excess carrier providing coverage for the period set forth above is currently providing applicable insurance coverage in accordance with the allocation provisions of the cost sharing agreement, but has not yet signed that agreement.

• Impact on Financial Statements

The models developed for determining the potential exposure and related insurance coverage were developed by outside consultants deemed to be experts in their respective fields with the forecast for asbestos related liabilities generated by NERA and the related insurance receivable projections developed by Marsh. The models contain numerous assumptions that significantly impact the results generated by the models. We believe the assumptions made are reasonable at the present time, but are subject to uncertainty based on the actual future outcome of our asbestos litigation. We determined that a ten year projection period is now appropriate as we have experience in addressing asbestos related lawsuits over the last few years to use as a baseline to project the liability over ten years. However, we do not believe we have sufficient data to justify a longer projection period at this time. As of December 31, 2014, the estimated liability and estimated insurance recovery for the ten year period through 2024 was $56.5 million and $53.0 million, respectively. There were no changes to these projections during the first six months of 2015. 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.

The amounts recorded for the asbestos-related liability 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 will incur additional charges for our asbestos liabilities and defense costs in the future, which could exceed existing reserves, but such excess amount cannot be reasonably estimated at this time. We will continue to vigorously defend ourselves and believe we have substantial unutilized insurance coverage to mitigate future costs related to this matter.

Other Environmental and General Litigation

• In the second quarter of 2010, the CT DEEP contacted us to discuss a disposal site in Killingly, Connecticut. We undertook internal due diligence work related to the site to better understand the issue and our alleged involvement. As a matter of procedure, we have submitted an insurance claim for the disposal site, but we currently do not know the nature and extent of any alleged contamination at the site, how many parties could be potentially involved in any remediation, if necessary, or the extent to which we could be deemed a potentially responsible party. CT DEEP has not made any assessment of the nature of any potential remediation work that may be done, nor have they made any indication of any potential costs associated with such remediation. Therefore, based on the facts and circumstances known to us at the present time, we are not able to estimate the probability of incurring a contingent liability related to this site, nor are we able to reasonably estimate any potential range of exposure at this time. As such, no reserve has been established for this matter at this time. We continually monitor this situation and are in correspondence with the CT DEEP as appropriate. When and if facts and circumstances related to this matter change, we will review our position and our ability to estimate the probability of any potential loss contingencies, as well as the range of any such potential exposure.

• The corporate headquarters of Rogers located in Rogers, Connecticut is part of the Connecticut Voluntary Corrective Action Program (VCAP). As part of this program, we have had conversations with the CT DEEP to begin to determine if any corrective actions need to be taken at the site related to any potential contamination issues. We are currently in the early stages of evaluating this matter and have initiated internal due diligence work related to the site to better understand any potential issues.

As of June 30, 2015, a reserve of $0.1 million was recorded for the continuing assessments to determine the extent of any potential remediation that may be required. However, at this time, it is currently unknown what the nature and extent of any potential contamination is at the site, nor what any potential remediation or associated costs would be if any such issues were found. Therefore, based on the facts and circumstances known to us at the present time, we are unable to estimate the probability of incurring a contingent liability related to environmental remediation at this site, nor are we able to reasonably estimate any potential range of exposure at this time. As such, no reserve specific to environmental remediation activity has been established for this matter at this time.

• In 2013, we became aware of a claim made by a sales agent/distributor in Europe for alleged improper termination of our relationship. The sales agent/distributor is seeking compensation for the terminated relationship. During 2014, a mediation process was initiated and was completed in the first quarter of 2015. We reached a settlement related to this matter in the amount of $0.5 million.

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.

Hedging Transactions and Derivative Financial Instruments

Hedging Transactions and Derivative Financial Instruments

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 special hedge accounting treatment as defined under the applicable accounting guidance. For derivative instruments that are designated and qualify for hedge accounting treatment (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 income associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of the future cash flows of the hedged item (i.e., the ineffective portion) if any, is recognized in the statements of income during the current period. For the six month periods ended June 30, 2015 and 2014, there was no hedge ineffectiveness.

We currently have twenty-three outstanding contracts to hedge exposure related to the purchase of copper in our Power Electronics Solutions and Advanced Connectivity Solutions 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 2015 and 2016 monthly copper exposure and do not qualify for hedge accounting treatment; therefore, any mark-to-market adjustments required on these contracts are recorded in the other income (expense), net line item in our condensed consolidated statements of income. 

During the six months ended June 30, 2015, we entered into Euro, Japanese Yen, Hungarian Forint, Korean Yuan and Chinese Yuan currency forward contracts. We entered into these foreign currency forward contracts to mitigate certain global balance sheet exposures. Certain contracts qualify for hedge accounting treatment, while others do not. Mark-to-market adjustments are recorded in the other income (expense), net line item in our condensed consolidated statements of income for those contracts that do not qualify for hedge accounting treatment. For those contracts that do qualify for hedge accounting treatment mark-to-market adjustments are recorded in other comprehensive income.

In July 2012, we entered into an interest rate swap to hedge the variable interest rate on our term loan debt. As of June 30, 2015, the remaining notional amount of the interest rate swap covers $32.5 million of our term loan debt. This transaction has been designated as a cash flow hedge and qualifies for hedge accounting treatment. At June 30, 2015, our term loan debt of $55.0 million and revolving line of credit borrowings of $125.0 million represent our total outstanding debt. At June 30, 2015, the rate charged on this debt was the 1 month London interbank offered rate ("LIBOR") at 0.1875% plus a spread of 1.625%.

The copper and foreign currency contracts that we have entered into as of June 30, 2015 are listed below:

Concentration of Credit Risk

By using derivative instruments, we are subject to credit and market risk. If a counterparty fails to fulfill its performance obligations under a derivative contract, our credit risk will equal the fair value of the derivative instrument. Generally, when the fair value of a derivative contract is positive, the counterparty owes the Company, thus creating a receivable risk for the Company. We minimize counterparty credit (or repayment) risk by entering into derivative transactions with major financial institutions with investment grade credit ratings.

On January 22, 2015, we acquired Arlon. For further detail on the goodwill and intangible assets recorded on the acquisition, see Note 5 - "Acquisition".

Amortization expense for the three and six month periods ended June 30, 2015 was approximately $2.8 million and $5.2 million, respectively. Amortization expense was $1.6 million and $3.1 million for the three and six month periods ended June 30, 2014, respectively. The estimated annual future amortization expense is $5.7 million, $10.4 million, $10.0 million, $9.5 million and $9.0 million for the remainder of 2015, 2016, 2017, 2018 and 2019, respectively.

The weighted average amortization period as of June 30, 2015, by intangible asset class, is presented in the table below:

Intangible Asset Class	Weighted Average Amortization Period
Trademarks and patents	4.3
Technology	4.8
Covenant not-to-compete	1.0

Approximately $5.3 million of indefinite-lived trademark intangible assets were acquired from the acquisitions of Curamik. These assets are assessed for impairment annually or when changes in circumstances indicated that the carrying values may be recoverable. The definite-lived intangibles are amortized using a fair value methodology that is based on the projected economic use of the related underlying asset.
