ROGERS CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Note 1 – Basis of Presentation
As used herein, the terms “Company,” “Rogers,” “we,” “us,” “our” and similar terms mean Rogers Corporation and its consolidated subsidiaries, unless the context indicates otherwise.
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information. Accordingly, these statements do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, the accompanying condensed consolidated financial statements include all normal recurring adjustments necessary for their fair presentation in accordance with GAAP. All significant intercompany balances and transactions have been eliminated.
Interim results are not necessarily indicative of results for a full year. For further information regarding our accounting policies, refer to the audited consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020. Refer to the discussion below for our restructuring activities significant accounting policy.
Through the fourth quarter of 2020, we operated three strategic operating segments: Advanced Connectivity Solutions (ACS), Elastomeric Material Solutions (EMS) and Power Electronics Solutions (PES), with the remaining operations, which represented our non-core businesses, being reported in a fourth operating segment, the Other operating segment. In the first quarter of 2021, we completed the realignment of our strategic business segments to reflect the combination of our ACS and PES businesses resulting in a new strategic business segment, Advanced Electronics Solutions (AES). The combination of these two complementary businesses with capabilities in both high power and high frequency applications is expected to enhance our overall value proposition to customers in multiple high-growth markets. As a result of our organizational and reporting structure changes, we re-evaluated the chief operating decision maker’s review and assessment of the Company’s operating performance for purposes of performance monitoring and resource allocation. We determined, based on the financial data utilized by the chief operating decision maker to assess segment performance and allocate resources among the Company’s strategic business segments, that we now have three operating segments under this new organizational and reporting structure: AES, EMS and Other. Reported results for the AES operating segment prior to 2021 represent the aggregation of the results for our former ACS and PES operating segments.

The accounting guidance for fair value measurements establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value:
•Level 1 – Quoted prices in active markets for identical assets or liabilities.
•Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
•Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
As a result of our pension termination and settlement efforts in late 2019 and the first half of 2020, we have a pension surplus investment balance, which is now accounted for as an available-for-sale investment as of June 2020. For additional information regarding this balance, refer to “Note 11 – Pension Benefits and Other Postretirement Benefits.” Available-for-sale investments measured at fair value on a recurring basis, categorized by the level of inputs used in the valuation, were as follows:

| Available-for-Sale Investment at Fair Value as of June 30, 2021
(Dollars in thousands) | Level 1 |  | Level 2 |  | Level 3 |  | Total
Pension surplus investment(1) | $ | 5,334 |  |  | $ | 2,391 |  |  | $ | — |  |  | $ | 7,725 |

| Available-for-Sale Investment at Fair Value as of December 31, 2020

Pension surplus investment(1) | $ | 6,706 |  |  | $ | 2,400 |  |  | $ | — |  |  | $ | 9,106 |

(1) This balance was invested in funds comprised of short-term cash and fixed income securities, and was recorded in the “Other long-term assets” line item in the condensed consolidated statements of financial position. As of June 30, 2021, the fair value of these investments approximated its carrying value.

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

For additional information on derivative contracts, refer to “Note 3 – Hedging Transactions and Derivative Financial Instruments.”
Note 3 – Hedging Transactions and Derivative Financial Instruments
We are exposed to certain risks related to our ongoing business operations. The primary risks being managed through our use of derivative instruments are foreign currency exchange rate risk and commodity pricing risk (primarily related to copper). We do not use derivative instruments for trading or speculative purposes. The valuation of derivative contracts used to manage each of these risks is described below:
•Foreign Currency – The fair value of any foreign currency option derivative is based upon valuation models applied to current market information such as strike price, spot rate, maturity date and volatility, and by reference to market values resulting from an over-the-counter market or obtaining market data for similar instruments with similar characteristics.
•Commodity – The fair value of copper derivatives is computed using a combination of intrinsic and time value valuation models, which are collectively a function of five primary variables: price of the underlying instrument, time to expiration, strike price, interest rate and volatility. The intrinsic valuation model reflects the difference between the strike price of the underlying copper derivative instrument and the current prevailing copper prices in an over-the-counter market at period end. The time value valuation model incorporates changes in the price of the underlying copper derivative instrument, the time value of money, the underlying copper derivative instrument’s strike price and the remaining time to the underlying copper derivative instrument’s expiration date from the period end date.
The guidance for the accounting and disclosure of derivatives and hedging transactions requires companies to recognize all of their derivative instruments as either assets or liabilities at fair value in the condensed consolidated statements of financial position. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies for hedge accounting treatment as defined under the applicable accounting guidance. For derivative instruments that are designated and qualify for hedge accounting treatment as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) in the condensed consolidated statements of comprehensive income (loss). This gain or loss is reclassified into earnings in the same line item of the condensed consolidated statements of operations associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings.
Foreign Currency
During the three months ended June 30, 2021, we entered into U.S. dollar, euro, and Korean won forward contracts. We entered into these foreign currency forward contracts to mitigate certain global transactional exposures. These contracts do not qualify for hedge accounting treatment. As a result, any fair value adjustments required on these contracts are recorded in “Other income (expense), net” in our condensed consolidated statements of operations in the period in which the adjustment occurred.

As of June 30, 2021, the notional values of the remaining foreign currency forward contracts were as follows:

Notional Values of Foreign Currency Derivatives
USD/CNH | $ | 19,919,008 |
KRW/USD | ₩ | 10,170,000,000 |
EUR/USD | € | 10,049,732 |

Commodity
As of June 30, 2021, we had 10 outstanding contracts to hedge exposure related to the purchase of copper in our AES operating segment. These contracts are held with financial institutions and are intended to offset rising copper prices and do not qualify for hedge accounting treatment. As a result, any fair value adjustments required on these contracts are recorded in “Other income (expense), net” in our condensed consolidated statements of operations in the period in which the adjustment occurred.
As of June 30, 2021, the volume of our copper contracts outstanding was as follows:

Volume of Copper Derivatives
July 2021 - September 2021 | 222 metric tons per month
October 2021 - December 2021 | 222 metric tons per month
January 2022 - March 2022 | 213 metric tons per month

In the table above, gross carrying amounts and accumulated amortization may differ from prior periods due to foreign exchange rate fluctuations.
Amortization expense was $3.1 million and $7.6 million for the three months ended June 30, 2021 and 2020, respectively, and $6.3 million and $11.2 million for the six months ended June 30, 2021 and 2020, respectively. The estimated future amortization expense is $6.2 million for the remainder of 2021 and $11.9 million, $11.3 million, $10.0 million and $8.5 million for 2022, 2023, 2024 and 2025, respectively.
The weighted average amortization period as of June 30, 2021, by definite-lived other intangible asset class, was as follows:

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

Note 7 – Earnings Per Share
Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding and all dilutive potential common shares outstanding.
The following table sets forth the computation of basic and diluted earnings per share:

(Dollars and shares in thousands, except per share amounts) | Three Months Ended |  | Six Months Ended
June 30, 2021 |  | June 30, 2020 |  | June 30, 2021 |  | June 30, 2020

Denominator: |  |  |  |  |  |  |
Weighted-average shares outstanding - basic | 18,729 |  |  | 18,676 |  |  | 18,721 |  |  | 18,673 |
Effect of dilutive shares | 117 |  |  | 5 |  |  | 89 |  |  | 13 |
Weighted-average shares outstanding - diluted | 18,846 |  |  | 18,681 |  |  | 18,810 |  |  | 18,686 |
Basic earnings per share | $ | 1.53 |  |  | $ | 0.78 |  |  | $ | 3.20 |  |  | $ | 1.49 |
Diluted earnings per share | $ | 1.52 |  |  | $ | 0.78 |  |  | $ | 3.18 |  |  | $ | 1.49 |

Dilutive shares are calculated using the treasury stock method and primarily include unvested restricted stock units. Anti-dilutive shares are excluded from the calculation of diluted shares and diluted earnings per share. For the three months ended June 30, 2021 and 2020, 1,769 shares and 55,961 shares were excluded, respectively.

Note 8 – Capital Stock and Equity Compensation
Equity Compensation
Performance-Based Restricted Stock Units
As of June 30, 2021, we had performance-based restricted stock units from 2021, 2020 and 2019 outstanding. These awards generally cliff vest at the end of a three-year measurement period. However, employees whose employment terminates during the measurement period due to death, disability, or, in certain cases, retirement may receive a pro-rata payout based on the number of days they were employed during the measurement period, except as noted below in Chief Executive Officer’s 2021 Equity Award Grants. Participants are eligible to be awarded shares ranging from 0% to 200% of the original award amount, based on certain defined performance measures.
The outstanding awards have one measurement criterion: the three-year total shareholder return (TSR) on our capital stock as compared to that of a specified group of peer companies. The TSR measurement criterion of the awards is considered a market condition. As such, the fair value of this measurement criterion was determined on the grant date using a Monte Carlo simulation valuation model. We recognize compensation expense on all of these awards on a straight-line basis over the vesting period with no changes for final projected payout of the awards. We account for forfeitures as they occur.
The following table sets forth the assumptions used in the Monte Carlo calculation for each material award granted in 2021 and 2020:

| February 10, 2021 |  | February 12, 2020
Expected volatility | 51.0% |  | 41.0%
Expected term (in years) | 2.9 |  | 2.9
Risk-free interest rate | 0.18% |  | 1.41%

Expected volatility – In determining expected volatility, we have considered a number of factors, including historical volatility.
Expected term – We use the vesting period of the award to determine the expected term assumption for the Monte Carlo simulation valuation model.
Risk-free interest rate – We use an implied “spot rate” yield on U.S. Treasury Constant Maturity rates as of the grant date for our assumption of the risk-free interest rate.
Expected dividend yield – We do not currently pay dividends on our capital stock; therefore, a dividend yield of 0% was used in the Monte Carlo simulation valuation model.
A summary of activity of the outstanding performance-based restricted stock units for the six months ended June 30, 2021 is presented below:

| Performance-Based Restricted Stock Units
Awards outstanding as of December 31, 2020 | 111,059 |
Awards granted | 39,955 |
Stock issued | — |
Awards cancelled | (34,020) |
Awards outstanding as of June 30, 2021 | 116,994 |

We recognized $1.1 million and $1.3 million of compensation expense for performance-based restricted stock units for the three months ended June 30, 2021 and 2020, respectively. We recognized $3.2 million and $2.7 million of compensation expense for performance-based restricted stock units for the six months ended June 30, 2021 and 2020, respectively.
Time-Based Restricted Stock Units
As of June 30, 2021, we had time-based restricted stock unit awards from 2021, 2020, 2019 and 2018 outstanding. The outstanding awards all ratably vest on the first, second and third anniversaries of the original grant date. However, employees whose employment terminates during the measurement period due to death, disability, or, in certain cases, retirement may receive a pro-rata payout based on the number of days they were employed subsequent to the last grant anniversary date, except as noted below in Chief Executive Officer’s 2021 Equity Award Grants. Each time-based restricted stock unit represents a right to receive one share of Rogers’ capital stock at the end of the vesting period. The fair value of the award is determined by the market value of the underlying stock price at the grant date. We recognize compensation expense on all of these awards on a straight-line basis over the vesting period. We account for forfeitures as they occur.

A summary of activity of the outstanding time-based restricted stock units for the six months ended June 30, 2021 is presented below:

| Time-Based Restricted Stock Units
Awards outstanding as of December 31, 2020 | 102,142 |
Awards granted | 46,998 |
Stock issued | (44,037) |
Awards cancelled | (5,450) |
Awards outstanding as of June 30, 2021 | 99,653 |

We recognized $1.9 million and $1.5 million of compensation expense for time-based restricted stock units for the three months ended June 30, 2021 and 2020, respectively. We recognized $3.7 million and $3.1 million of compensation expense for performance-based restricted stock units for the six months ended June 30, 2021 and 2020, respectively.
Chief Executive Officer’s 2021 Equity Award Grants
The terms of the performance-based and time-based restricted stock unit awards granted to our Chief Executive Officer (CEO), Bruce Hoechner, in February 2021 were modified from the standard language provisions from prior year awards to allow for accelerated vesting of the full awards provided certain criteria are met. Accounting Standards Codification (ASC) Topic 718: Compensation—Stock Compensation requires companies that allow for accelerated vesting of employees’ unvested equity upon retirement to recognize the expense from the date of grant to the date the employee becomes eligible to retire – regardless of whether or not the employee actually retires when he or she is eligible to retire. As a result, the $4.0 million of expense related to the awards granted on February 10, 2021 to our CEO, which provide for immediate vesting upon retirement, will be expensed from the date of the grant, February 10, 2021, through his retirement eligibility date, November 9, 2021.
Deferred Stock Units
We grant deferred stock units to non-management directors. These awards are fully vested on the date of grant and the related shares are generally issued on the 13-month anniversary of the grant date unless the individual elects to defer the receipt of those shares. Each deferred stock unit results in the issuance of one share of Rogers’ capital stock. The grant of deferred stock units is typically done annually during the second quarter of each year. The fair value of the award is determined by the market value of the underlying stock price at the grant date.
A summary of activity of the outstanding deferred stock units for the six months ended June 30, 2021 is presented below:

| Deferred Stock Units
Awards outstanding as of December 31, 2020 | 12,450 |
Awards granted | 6,450 |
Stock issued | (9,400) |
Awards outstanding as of June 30, 2021 | 9,500 |

We recognized $1.2 million of compensation expense related to deferred stock units for the three and six months ended June 30, 2021, and $1.0 million of compensation expense for the three and six months ended June 30, 2020.
Note 9 – Debt
On October 16, 2020, we entered into the Fourth Amended and Restated Credit Agreement with JPMorgan Chase Bank, N.A, as administrative agent, and the lenders party thereto (the Fourth Amended Credit Agreement). The Fourth Amended Credit Agreement amends and restates the Third Amended Credit Agreement, and provides for a revolving credit facility with up to a $450.0 million borrowing capacity, with sublimits for multicurrency borrowings, letters of credit and swing-line notes, in addition to a $175.0 million accordion feature. Borrowings may be used to finance working capital needs, for letters of credit and for general corporate purposes in the ordinary course of business, including the financing of permitted acquisitions (as defined in the Fourth Amended Credit Agreement). The Fourth Amended Credit Agreement extends the maturity, the date on which all amounts borrowed or outstanding under the Fourth Amended Credit Agreement are due, from February 17, 2022 to March 31, 2024.
All obligations under the Fourth Amended Credit Agreement are guaranteed by each of our existing and future material domestic subsidiaries, as defined in the Fourth Amended Credit Agreement (the Guarantors). The obligations are also secured by a Fourth Amended and Restated Pledge and Security Agreement, dated as of October 16, 2020, entered into by us and the Guarantors which grants to the administrative agent, for the benefit of the lenders, a security interest, subject to certain
14

exceptions, in substantially all of our and the Guarantors’ non-real estate assets. These assets include, but are not limited to, receivables, equipment, intellectual property, inventory, and stock in certain subsidiaries.
Borrowings under the Fourth Amended Credit Agreement can be made as alternate base rate loans or euro-currency loans. Alternate base rate loans bear interest at a base reference rate plus a spread of 62.5 to 100.0 basis points, depending on our leverage ratio. The base reference rate is the greatest of (a) the prime rate in effect on such day, (b) the Federal Reserve Bank of New York rate in effect on such day plus ½ of 1%, and (c) the adjusted LIBOR for a one month interest period in dollars on such day (or if such day is not a business day, the immediately preceding business day) plus 1%. Euro-currency loans bear interest based on adjusted LIBOR plus a spread of 162.5 to 200.0 basis points, depending on our leverage ratio. Based on our leverage ratio on June 30, 2021, the spread was 162.5 basis points.
In addition to interest payable on the principal amount of indebtedness outstanding from time to time under the Fourth Amended Credit Agreement, we are required to pay a quarterly fee of 25 to 35 basis points (based upon our leverage ratio) of the unused amount of the lenders’ commitments under the Fourth Amended Credit Agreement.
The Fourth Amended Credit Agreement contains customary representations and warranties, covenants, mandatory prepayments and events of default under which our payment obligations may be accelerated. If an event of default occurs, the lenders may, among other things, terminate their commitments and declare all outstanding borrowings to be immediately due and payable together with accrued interest and fees. The financial covenants include requirements to maintain (1) a total net leverage ratio of no more than 3.25 to 1.00, subject to a one-time election to increase the maximum total net leverage ratio to 3.50 to 1.00 for one fiscal year in connection with a permitted acquisition, and (2) an interest coverage ratio of no less than 3.00 to 1.00. We are permitted to net up to $50.0 million of unrestricted domestic cash and cash equivalents against indebtedness in the calculation of the total net leverage ratio.
The Fourth Amended Credit Agreement generally permits us to pay cash dividends to our shareholders, provided that (i) no default or event of default has occurred and is continuing or would result from the dividend payment and (ii) our total net leverage ratio does not exceed 2.75 to 1.00. If our total net leverage ratio exceeds 2.75 to 1.00, we may nonetheless make up to $20.0 million in restricted payments, including cash dividends, during the fiscal year, provided that no default or event of default has occurred and is continuing or would result from the payments. Our total net leverage ratio did not exceed 2.75 to 1.00 as of June 30, 2021.
We did not borrow anything under the Fourth Amended Credit Agreement for the three and six months ended June 30, 2021. During the three months ended March 31, 2020, we borrowed $150.0 million under the Third Amended Credit Agreement (prior to its restatement) as a precautionary measure in order to increase our cash position and preserve financial flexibility given current uncertainty in the global markets resulting from the COVID-19 pandemic. We did not borrow anything further for the three months ended June 30, 2020. We are not required to make any quarterly principal payments under the Fourth Amended Credit Agreement. However, we made $4.0 million and $25.0 million of discretionary principal payments on our revolving credit facility for the three and six months ended June 30, 2021, respectively, and we made $50.0 million of discretionary principal payments for both of the three and six month periods ended June 30, 2020.
We had no outstanding borrowings under our revolving credit facility as of June 30, 2021, and $25.0 million as of December 31, 2020. We had $2.0 million and $2.3 million of outstanding line of credit issuance costs as of June 30, 2021 and December 31, 2020, respectively, which will be amortized over the life of the Fourth Amended Credit Agreement.
Note 10 - Leases
We had a finance lease obligation related to our manufacturing facility in Eschenbach, Germany. Under the terms of the lease agreement, we had an option to purchase the property upon the expiration of the lease on June 30, 2021 at a price which was the greater of (i) the then-current market value or (ii) the residual book value of the land including the buildings and installations thereon. We exercised this purchase option with a net cash payment of $5.0 million on June 30, 2021, extinguishing the remaining finance lease obligation and finance lease right-of-use asset related to this facility. Our finance lease obligation related to this facility was $4.2 million just prior to the exercise of the purchase option and $4.5 million as of December 31, 2020. The finance lease right-of-use asset balance for this facility was $6.1 million just prior to the exercise of the purchase option and $6.5 million as of December 31, 2020, respectively. Accumulated amortization related to this finance lease right-of-use asset was $4.5 million just prior to the exercise of the purchase option and as of June 30, 2021. The aggregate of all other finance lease obligations, finance lease right-of-use assets and related accumulated amortization, were immaterial as of June 30, 2021 and December 31, 2020.
Amortization expense related to our finance lease right-of-use assets, which is primarily included in the “Cost of sales” line item of the condensed consolidated statements of operations, was immaterial for each of the three- and six-month periods ended June 30, 2021 and 2020. Interest expense related to our finance lease obligations, which is included in the “Interest expense, net” line item of the condensed consolidated statements of operations, was immaterial for each of the three- and six-month periods ended June 30, 2021 and 2020. Payments made on the principal portion of our finance lease obligations were
15

immaterial for each of the three- and six-month periods ended June 30, 2021 and 2020, excluding the $5.0 million net cash payment to exercise the Eschenbach, Germany manufacturing facility purchase option.
We have operating leases primarily related to building space and vehicles. Renewal options are included in the lease term to the extent we are reasonably certain to exercise the option. The exercise of lease renewal options is at our sole discretion. We account for lease components separately from non-lease components. The incremental borrowing rate represents our ability to borrow on a collateralized basis over a similar lease term.
Our expenses and payments for operating leases were as follows:

| Three Months Ended |  | Six Months Ended

Note 11 – Pension Benefits and Other Postretirement Benefits
Pension and Other Postretirement Benefit Plans
As of June 30, 2021, we had one qualified noncontributory defined benefit pension plan, the Rogers Corporation Employees’ Pension Plan (the Union Plan), which was frozen and ceased accruing benefits in 2013.
Additionally, we sponsor other postretirement benefit plans, including multiple fully insured or self-funded medical plans and life insurance plans for certain retirees. The measurement date for all plans is December 31 st for each respective plan year.
Pension Termination Surplus Funds
On October 17, 2019, our Chief Executive Officer approved the termination of the Rogers Corporation Defined Benefit Pension Plan (following its merger with the Hourly Employees Pension Plan of Arlon LLC, Microwave Material and Silicone Technologies Divisions, Bear, Delaware (collectively, the Merged Plan)). We provided participants of the Merged Plan an option to elect either a lump sum distribution or an annuity. A group annuity contract was purchased with an insurance company for all participants who did not elect a lump sum distribution. The insurance company became responsible for administering and paying pension benefit payments effective January 1, 2020.
Upon completion of the pension termination and settlement processes for the Merged Plan, we had a $9.7 million remaining pension surplus investment balance. In July 2020, we transferred $7.4 million of the pension surplus investment balance to a suspense account held within a trust for the Rogers Employee Savings and Investment Plan (RESIP), a 401(k) plan for domestic employees. The investment balance not transferred to the trust suspense account will be used to pay any final plan expenses, after which the remainder of these funds will be moved to the RESIP trust suspense account. The funds in the RESIP trust suspense account have been, and will continue to be, used to fund certain employer contributions. As of June 30, 2021, the combined remaining pension surplus investment balance was approximately $7.7 million.

Employer Contributions
There were no required or voluntary contributions made to the Union Plan or the Merged Plan for each of the three and six-month periods ended June 30, 2021 and 2020. Additionally, we are not required to make additional contributions to the Union Plan for the remainder of 2021.
As there is no funding requirement for the other postretirement benefit plans, we funded these benefit payments as incurred, which were immaterial for each of the three and six-month periods ended June 30, 2021 and 2020, using cash from operations.

Note 12 – Commitments and Contingencies
We are currently engaged in the following material environmental and legal proceedings:
Voluntary Corrective Action Program
Our location in Rogers, Connecticut is part of the Connecticut Voluntary Corrective Action Program (VCAP). As part of this program, we partnered with the Connecticut Department of Energy and Environmental Protection (CT DEEP) to determine the corrective actions to be taken at the site related to contamination issues. We evaluated this matter and completed internal due diligence work related to the site in the fourth quarter of 2015. Remediation activities on the site are ongoing and are recorded as reductions to the accrual as they are incurred. We incurred $1.8 million of aggregate remediation costs through June 30, 2021, and the accrual for future remediation efforts is $0.9 million.
Asbestos
Overview
We, like many other industrial companies, have been named as a defendant in a number of lawsuits filed in courts across the country by persons alleging personal injury from exposure to products containing asbestos. We have never mined, milled, manufactured or marketed asbestos; rather, we made and provided to industrial users a limited number of products that contained encapsulated asbestos, but we stopped manufacturing these products in the late 1980s. Most of the claims filed against us involve numerous defendants, sometimes as many as several hundred.
The following table summarizes the change in number of asbestos claims outstanding for the six months ended June 30, 2021:

| Asbestos Claims
Claims outstanding as of January 1, 2021 | 561 |
New claims filed | 64 |
Pending claims concluded(1) | (77) |
Claims outstanding as of June 30, 2021 | 548 |

(1) For the six months ended June 30, 2021, 71 claims were dismissed and 6 claims were settled. Settlements totaled approximately $0.5 million for the six months ended June 30, 2021.
Impact on Financial Statements
We recognize a liability for asbestos-related contingencies that are probable of occurrence and reasonably estimable. In connection with the recognition of liabilities for asbestos-related matters, we record asbestos-related insurance receivables that are deemed probable.
The liability projection period covers all current and future indemnity and defense costs through 2064, which represents the expected end of our asbestos liability exposure with no further ongoing claims expected beyond that date. This conclusion was based on our history and experience with the claims data, the diminished volatility and consistency of observable claims data, the period of time that has elapsed since we stopped manufacturing products that contained encapsulated asbestos and an expected downward trend in claims due to the average age of our claimants, which is approaching the average life expectancy.
To date, the indemnity and defense costs of our asbestos-related product liability litigation have been substantially covered by insurance. Although we have exhausted coverage under some of our insurance policies, we believe that we have applicable primary, excess and/or umbrella coverage for claims arising with respect to most of the years during which we manufactured and marketed asbestos-containing products. In addition, we have entered into a cost sharing agreement with most of our primary, excess and umbrella insurance carriers to facilitate the ongoing administration and payment of claims covered by the carriers. The cost sharing agreement may be terminated by any party, but will continue until a party elects to terminate it. As of the filing date for this report, the agreement has not been terminated, and no carrier had informed us it intended to terminate the agreement. We expect to continue to exhaust individual primary, excess and umbrella coverages over time, and there is no assurance that such exhaustion will not accelerate due to additional claims, damages and settlements or that coverage will be available as expected. We are responsible for uninsured indemnity and defense costs, and we incurred an immaterial amount of expenses for each of the three- and six-month periods ended June 30, 2021 and 2020, respectively, related to such costs.
The amounts recorded for the asbestos-related liability and the related insurance receivables are based on facts known at the time and a number of assumptions. However, projecting future events, such as the number of new claims to be filed each year, the average cost of disposing of such claims, the length of time it takes to dispose of such claims, coverage issues among insurers and the continuing solvency of various insurance companies, as well as the numerous uncertainties surrounding asbestos litigation in the United States, could cause the actual liability and insurance recoveries for us to be higher or lower than those projected or recorded.
18

Changes recorded in the estimated liability and estimated insurance recovery based on projections of asbestos litigation and corresponding insurance coverage, result in the recognition of expense or income.
Our projected asbestos-related liabilities and insurance receivables were as follows:

(Dollars in thousands) | June 30, 2021 |  | December 31, 2020
Asbestos-related liabilities | $ | 73,084 |  |  | $ | 73,235 |
Asbestos-related insurance receivables | $ | 66,793 |  |  | $ | 66,793 |

General
In addition to the above issues, the nature and scope of our business brings us in regular contact with the general public and a variety of businesses and government agencies. Such activities inherently subject us to the possibility of litigation, including environmental and product liability matters that are defended and handled in the ordinary course of business. We have established accruals for matters for which management considers a loss to be probable and reasonably estimable. It is the opinion of management that facts known at the present time do not indicate that such litigation will have a material adverse impact on our results of operations, financial position or cash flows.
Note 13 – Income Taxes
Our effective income tax rate was 25.6% and 30.6% for the three months ended June 30, 2021 and 2020, respectively. The decrease from the second quarter of 2020 was primarily due to the decrease in the current quarter accruals for reserves of unrecognized tax benefits and the pretax mix across jurisdictions with disparate tax rates, partially offset by the second quarter of 2020 beneficial impact of changes in valuation allowance related to research and development (R&D) credits. Our effective income tax rate was 25.4% and 26.1% for the six months ended June 30, 2021 and 2020, respectively. The decrease from the first half of 2020 was primarily due to the decrease in the current quarter accruals of reserves of unrecognized tax benefits and the pretax mix across jurisdictions with disparate tax rates, partially offset by the first half of 2020 beneficial impact of changes in valuation allowance related to R&D credits.
The total amount of unrecognized tax benefits as of June 30, 2021 was $15.5 million, of which $14.9 million would affect our effective tax rate if recognized. Additionally, the balance of unrecognized tax benefits as of June 30, 2021 also included $0.6 million of tax benefits that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes.
We recognize interest and penalties related to unrecognized tax benefits through income tax expense. As of June 30, 2021, we had $1.5 million accrued for the payment of interest.
We are subject to taxation in the U.S. and various state and foreign jurisdictions. Our tax years from 2016 through 2020 are subject to examination by the tax authorities. With few exceptions, we are no longer subject to U.S. federal, state, local and foreign examinations by tax authorities for the years before 2016.

In early February 2021, there was a fire at our UTIS manufacturing facility in Ansan, South Korea, which manufactures eSorba® polyurethane foams used in portable electronics and display applications. The site was safely evacuated and there were no reported injuries; however, there was extensive damage to the manufacturing site and some damage to nearby property. The cause of the fire is still under investigation. Operations at this facility will be disrupted into at least the first quarter of 2022. We are currently evaluating alternative facility options.
We recognized fixed asset write-offs and inventory charges of $0.9 million and $0.3 million, respectively, related to property destroyed in the fire for the six months ended June 30, 2021. Additionally, we recognized a $0.5 million contingent liability pertaining to our obligations for the fire damage to the building in connection with the underlying lease agreement. We have incurred $1.1 million and $1.6 million of fees for various professional services for the three and six months ended June 30, 2021, respectively, in connection with the assessment of the fire and the efforts to rebuild and resume operations. Further, we incurred $0.6 million and $0.8 million of compensation and benefits for UTIS manufacturing employees, subsequent to the fire, for the three and six months ended June 30, 2021, respectively. In connection with the UTIS fire, we have recognized anticipated insurance recoveries of $0.4 million and $1.5 million related to our ongoing insurance claim for property damage and compensation and benefits of hourly employees, less the applicable $0.3 million deductible, for the three and six months ended June 30, 2021, respectively.
Based on the facts and circumstances known to us as of our filing, while we are aware of other potential liabilities, we are unable presently to estimate the probability or amount of any further contingent liabilities associated with damages to nearby property or other potential costs due to the fire at our UTIS manufacturing facility. As such, no further reserves have been established at this time. We will continue to re-assess as additional information becomes available.

Note 16 – Recent Accounting Standards
Recently Adopted Standards Reflected in Our 2021 Financial Statements
In August 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. Under ASU 2020-06, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The new guidance also requires the if-converted method be applied for all convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted. Adoption of the standard requires using either the modified retrospective or the retrospective approach. We adopted this standard in January 2021, and it did not have a material effect on our condensed consolidated financial statements.
In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. Under ASU 2019-12, the new guidance removes certain exceptions to the general principles in Topic 740. The new guidance also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 is effective for our annual reporting periods beginning after December 15, 2020. The transition method (retrospective, modified retrospective, or prospective approach) related to this standard depends on the applicable guidance, and all amendments for which there is no transition guidance specified, are to be applied on a prospective basis. We adopted this standard in January 2021, and it did not have a material effect on our condensed consolidated financial statements.

Company Background and Strategy
Rogers Corporation designs, develops, manufactures and sells high-performance and high-reliability engineered materials and components to meet our customers’ demanding challenges. We operate two strategic operating segments: Advanced Electronics Solutions (AES) and Elastomeric Material Solutions (EMS). The remaining operations, which represent our non-core businesses, are reported in our Other operating segment. We have a history of innovation and have established Innovation Centers for our research and development (R&D) activities in Chandler, Arizona, Burlington, Massachusetts, Eschenbach, Germany and Suzhou, China. We are headquartered in Chandler, Arizona.
Our growth strategy is based upon the following principles: (1) market-driven organization, (2) innovation leadership, (3) synergistic mergers and acquisitions, and (4) operational excellence. As a market-driven organization, we are focused on growth drivers, including advanced mobility and advanced connectivity. More specifically, in addition to the impact of COVID-19 discussed below, the key medium- to long-term trends currently affecting our business include the increasing use of advanced driver assistance systems (ADAS) and increasing electrification of vehicles, including electric and hybrid electric vehicles (EV/HEV), in the automotive industry and the growth of 5G smartphones in the portable electronics industry. In addition to our focus on advanced mobility and advanced connectivity in the automotive, portable electronics and telecommunications industries, we sell into a variety of other markets including general industrial, aerospace and defense, mass transit, clean energy and connected devices.
Our sales and marketing approach is based on addressing these trends, while our strategy focuses on factors for success as a manufacturer of engineered materials and components: performance, quality, service, cost, efficiency, innovation and technology. We have expanded our capabilities through organic investment and acquisitions and strive to ensure high quality solutions for our customers. We continue to review and re-align our manufacturing and engineering footprint in an effort to maintain a leading competitive position globally. We have established or expanded our capabilities in various locations in support of our customers’ growth initiatives.
We seek to enhance our operational and financial performance by investing in research and development, manufacturing and materials efficiencies, and new product initiatives that respond to the needs of our customers. We strive to evaluate operational and strategic alternatives to improve our business structure and align our business with the changing needs of our customers and major industry trends affecting our business.
COVID-19 Update
The global COVID-19 pandemic has affected and continues to affect Rogers’ business and operations, although to a lesser extent than the first half of 2020. In response to the outbreak, Rogers prioritized the safety and well-being of its employees—including implementing social distancing initiatives in its facilities, providing remote working arrangements for certain employees, expanding personal protective equipment usage, enhancing plant hygiene processes, and extending employee benefits, which increased our expenses—while at the same time taking actions to preserve business continuity. Our non-manufacturing employees transitioned seamlessly to remote working arrangements and are effectively collaborating both internally and with our customers. In some cases, based on local conditions, non-manufacturing employees have returned to their worksites. We expect that the COVID-19 pandemic will have a continuing but uncertain impact on our business and operations in the short- and medium-term.
Due to the above circumstances and as described generally in this Form 10-Q, our results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year.
Executive Summary
The following key highlights and factors should be considered when reviewing our results of operations, financial position and liquidity:
•In the second quarter of 2021 as compared to the second quarter of 2020, our net sales increased 22.9% to $234.9 million, our gross margin increased approximately 160 basis points to 38.2% from 36.6%, and operating income increased approximately 420 basis points to 15.2% from 11.0%. In the first half of 2021 as compared to the first half of 2020, our net sales increased approximately 19.0% to $464.2 million, our gross margin increased approximately 380 basis points to 38.6% from 34.8%, and operating income increased approximately 580 basis points to 15.7% from 9.9%.
•We made $25.0 million of discretionary principal payments on our revolving credit facility during the first half of 2021.
•We recognized $0.7 million of restructuring charges in the second quarter of 2021 and $2.3 million of restructuring charges in the first half of 2021, related to the manufacturing footprint optimization plans involving certain Europe and Asia manufacturing locations, primarily impacting our AES operating segment.
27

•In early February 2021, there was a fire at our UTIS manufacturing facility in Ansan, South Korea. This facility manufactures eSorba® polyurethane foams used in portable electronics and display applications. Operations at this facility will be disrupted into at least the first quarter of 2022. We are currently evaluating alternative facility options. We recognized net expense of $1.5 million in the second quarter of 2021 and $2.8 million in the first half of 2021, related to the financial impacts from the fire, which consisted of write-offs of fixed assets and inventory destroyed and/or damaged in the fire, professional services, costs incurred due to obligations under our manufacturing facility lease agreement, compensation and benefits for certain of our UTIS employees, partially offset by the recognition of certain anticipated insurance recoveries.
•We incurred incremental transaction costs of $0.5 million and $3.3 million in the second quarter of 2021 and the second quarter of 2020, respectively, and incurred incremental transaction costs of $1.1 million and $4.0 million in the first half of 2021 and the first half of 2020, respectively, due to the COVID-19 pandemic.

Net sales increased by 22.9% in the second quarter of 2021 compared to the second quarter of 2020. Our AES and EMS operating segments had net sales increases of 20.9% and 24.7%, respectively. The increase in net sales was primarily due to higher net sales in the ADAS, EV/HEV, aerospace and defense and clean energy markets in our AES operating segment and higher net sales in the EV/HEV, general industrial, consumer and automotive markets in our EMS operating segment. The increase was partially offset by lower net sales in the wireless infrastructure market in our AES operating segment and lower net sales in the mass transit market in our EMS operating segment. Net sales were favorably impacted by foreign currency impacts of $8.1 million, or 4.3%, due to the appreciation in value of the euro and Chinese renminbi relative to the U.S. dollar.
Net sales increased by 19.0% in the first half of 2021 compared to the first half of 2020. Our AES and EMS operating segments had net sales increases of 19.7% and 16.8%, respectively. The increase in net sales was primarily due to higher net sales in the ADAS, EV/HEV, aerospace and defense and clean energy markets in our AES operating segment and higher net sales in the EV/HEV, general industrial, consumer and automotive markets in our EMS operating segment. The increase was partially offset by lower net sales in the wireless infrastructure market in our AES operating segment and lower net sales in the mass
28

transit market in our EMS operating segment. Net sales were favorably impacted by foreign currency impacts of $16.3 million, or 4.2%, due to the appreciation in value of the euro and Chinese renminbi relative to the U.S. dollar.
Gross margin as a percentage of net sales increased approximately 160 basis points to 38.2% in the second quarter of 2021 compared to 36.6% in the second quarter of 2020. Gross margin in the second quarter of 2021 was favorably impacted by higher volume and favorable absorption of fixed overhead costs in our AES and EMS operating segments, favorable product mix in our EMS operating segment, favorable productivity improvements in our AES operating segment, as well as a lower inventory reserves provision in our EMS operating segment. This was partially offset by higher commodity and raw material costs as well as higher freight, duties and tariffs expenses in our AES and EMS operating segments, unfavorable product mix in our AES operating segments and unfavorable productivity performance due to raw material shortages in our EMS operating segment. The higher freight, duties and tariffs expenses were primarily due to the recognition in the second quarter of 2020 of $3.3 million of Chinese duty tax recoveries.
Gross margin as a percentage of net sales increased approximately 380 basis points to 38.6% in the first half of 2021 compared to 34.8% in the first half of 2020. Gross margin in the first half of 2021 was favorably impacted by higher volume and favorable absorption of fixed overhead costs in our AES and EMS operating segments, favorable product mix in our EMS operating segment, favorable productivity improvements in our AES operating segment and a lower inventory reserves provision in our EMS operating segment. This was partially offset by higher commodity and raw material costs as well as higher freight, duties and tariffs expenses in our AES and EMS operating segments, unfavorable product mix in our AES operating segment and unfavorable productivity performance due to raw material shortages in our EMS operating segment. The higher freight, duties and tariffs expenses were primarily due to the recognition in the second quarter of 2020 of $3.3 million of Chinese duty tax recoveries.
Our UTIS net sales were only slightly impacted by the fire at our UTIS manufacturing facility in Ansan, South Korea as a result of selling our undamaged finished goods inventory during the remainder of the first quarter of 2021. In the second quarter of 2021, we experienced a greater impact to our net sales due to the continued disruption to our UTIS operations. In the third quarter of 2021, we expect a similar impact to our net sales as the second quarter of 2021.
In the first quarter of 2021, our net sales were largely unaffected by global supply chain disruptions, but we began seeing some greater impacts as we exited the quarter. In the second quarter of 2021, the impact of supply constraints and raw material cost increases, primarily due to the weather interruptions along the U.S. Gulf Coast as well as commodity price increases, somewhat tempered our net sales growth and gross margin results. In the third quarter of 2021, we expect these issues to continue, but to a lesser extent.
We incurred incremental transaction costs associated with the temporary additional benefits established under our dependent care, premium pay and sick pay programs in response to the COVID-19 pandemic, as well as additional safety supplies. These costs impacted our gross margin by $0.4 million and $3.0 million in the second quarter of 2021 and the second quarter of 2020, respectively, and $1.1 million and $3.6 million in the first half of 2021 and the first half of 2020, respectively.

Selling, general and administrative (SG&A) expenses increased 7.8% in the second quarter of 2021 from the second quarter of 2020, primarily due to a $5.2 million increase in total compensation and benefits, a $0.9 million increase in software expenses, a $0.5 million increase in recruiting/relocation/training expenses, a $0.3 million increase in travel and entertainment expenses and a $0.1 million increase in depreciation. This was partially offset by a $4.5 million decrease in other intangible assets amortization and a $0.1 million decrease in environmental charges.
SG&A expenses increased 6.5% in the first half of 2021 from the first half of 2020, primarily due to an $7.7 million increase in total compensation and benefits, a $1.7 million increase in software expenses and a $0.6 million increase in recruiting/relocation/training expenses. This was partially offset by a $5.0 million decrease in other intangible assets amortization and a $0.9 million decrease in travel and entertainment expenses.
The decrease in amortization expense for the three and six months ended June 30, 2021 was due to the acceleration of amortization expense related to our DSP customer relationships and trademarks and trade names definite-lived other intangible assets, which were both accelerated to be fully amortized by December 31, 2020 due to an adjustment to their remaining useful lives. We recognized amortization expense for our DSP definite-lived other intangible assets of $0.1 million and $4.4 million in the second quarter of 2021 and the second quarter of 2020, respectively, and $0.1 million and $4.8 million in the first half of 2021 and the first half of 2020, respectively.

We incurred restructuring charges and related expenses associated with our manufacturing footprint optimization plans involving certain Europe and Asia manufacturing locations. We recognized $0.7 million and $2.3 million of restructuring charges and related expenses pertaining to these restructuring projects in the second quarter of 2021 and the first half of 2021, respectively. For additional information, refer to “Note 15 – Supplemental Financial Information” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q.
With respect to other operating (income) expense, net, we recognized expense of $0.9 million and $2.1 million in the second quarter of 2021 and the first half of 2021, respectively, primarily related to the financial impacts from the fire at our UTIS manufacturing facility in Ansan, South Korea in the first quarter of 2021. This impact consisted of write-offs of fixed assets and inventory destroyed and/or damaged in the fire, professional services, costs incurred due to obligations under our manufacturing facility lease agreement, compensation and benefits for certain of our UTIS employees, partially offset by the recognition of certain anticipated insurance recoveries. There may be other potential costs that cannot be reasonably foreseen or estimated at this time and we continue to evaluate information as it becomes available.

As of June 30, 2021, we had two unconsolidated joint ventures, each 50% owned: Rogers INOAC Corporation (RIC) and Rogers INOAC Suzhou Corporation (RIS). Equity income in those unconsolidated joint ventures increased 88.8% in the second quarter of 2021 from the second quarter of 2020, and increased 83.5% in the first half of 2021 from the first half of 2020. On a quarter-to-date basis and a year-to-date basis, the increase was due to higher net sales, driven by strong sales in the portable electronics and general industrial markets, and improved operational performance for both RIS and RIC, primarily due to higher utilization of production capacity.

Other income (expense), net increased to income of $1.2 million in the second quarter of 2021 from income of $0.6 million in the second quarter of 2020. On a quarter-to-date basis, the increase was due to favorable impacts from our copper derivative contracts and foreign currency transactions, partially offset by unfavorable impacts from our foreign currency derivative contracts.

The decrease on quarter-to-date and year-to-date bases was primarily due to a lower weighted-average outstanding balance for our borrowings under our revolving credit facility. We expect interest expense, net to decrease on quarter-to-date and year-to-date bases in the third quarter of 2021 from the third quarter of 2020 primarily due to a lower weighted-average outstanding balance for our borrowings under our revolving credit facility.

Effective tax rate | 25.6 | % |  | 30.6 | % |  | 25.4 | % |  | 26.1 | %

Our effective income tax rate was 25.6% and 30.6% for the three months ended June 30, 2021 and 2020, respectively. The decrease from the second quarter of 2020 was primarily due to the decrease in the current quarter accruals for reserves of unrecognized tax benefits and the pretax mix across jurisdictions with disparate tax rates, partially offset by the second quarter of 2020 beneficial impact of changes in valuation allowance related to R&D credits. Our effective income tax rate was 25.4% and 26.1% for the six months ended June 30, 2021 and 2020, respectively. The decrease from the first half of 2020 was primarily due to the decrease in the current quarter accruals of reserves of unrecognized tax benefits and the pretax mix across jurisdictions with disparate tax rates, partially offset by the first half of 2020 beneficial impact of changes in valuation allowance related to R&D credits.

AES net sales increased by 20.9% in the second quarter of 2021 compared to the second quarter of 2020. The increase in net sales over the second quarter of 2020 was primarily driven by higher net sales in the ADAS, EV/HEV, aerospace and defense and clean energy markets, partially offset by lower net sales in the wireless infrastructure market. Net sales were favorably impacted by foreign currency fluctuations of $5.4 million, or 4.7%, due to the appreciation in value of the euro and Chinese renminbi relative to the U.S. dollar.
AES net sales increased by 19.7% in the first half of 2021 compared to the first half of 2020. The increase in net sales over the first half of 2020 was primarily driven by higher net sales in the ADAS, EV/HEV, aerospace and defense and clean energy markets, partially offset by lower net sales in the wireless infrastructure market. Net sales were favorably impacted by foreign currency fluctuations of $10.7 million, or 4.7%, due to the appreciation in value of the euro and Chinese renminbi relative to the U.S. dollar.
Operating income increased by 7.1% in the second quarter of 2021 from the second quarter of 2020. The increase in operating income was primarily due to higher volume, favorable absorption of fixed overhead costs and favorable productivity improvements. This was partially offset by higher commodity costs, unfavorable product mix and higher freight, duties and tariffs expenses. The higher freight, duties and tariffs expenses were primarily due to the recognition in the second quarter of 2020 of $3.3 million of Chinese duty tax recoveries. As a percentage of net sales, operating income in the second quarter of 2021 was 13.0%, an approximately 170 basis point decrease as compared to the 14.7% reported in the second quarter of 2020.

higher freight, duties and tariffs expenses were primarily due to the recognition in the second quarter of 2020 of $3.3 million of Chinese duty tax recoveries. As a percentage of net sales, operating income in the first half of 2021 was 12.2%, an approximately 260 basis point increase as compared to the 9.6% reported in the first half of 2020.
Additionally, we incurred restructuring charges and related expenses associated with our manufacturing footprint optimization plans involving certain Europe and Asia manufacturing locations. We recognized $0.7 million and $2.3 million of restructuring charges and related expenses pertaining to these restructuring projects in the second quarter of 2021 and the first half of 2021, respectively. For additional information, refer to “Note 15 – Supplemental Financial Information” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q.
In the first quarter of 2021, our net sales were largely unaffected by global supply chain disruptions, but we began seeing some greater impacts as we exited the quarter. In the second quarter of 2021, the impact of higher commodity costs tempered our gross margin results. In the third quarter of 2021, we expect these issues to persist, but to a lesser extent due to commercial actions we have begun to take to address these higher costs.
Our AES operating segment incurred incremental transaction costs associated with the temporary additional benefits established under our dependent care, premium pay and sick pay programs in response to the COVID-19 pandemic, as well as additional safety supplies. These costs impacted our operating income by $0.3 million and $1.9 million in the second quarter of 2021 and the second quarter of 2020, respectively, and $0.7 million and $2.3 million in the first half of 2021 and the first half of 2020, respectively.

EMS net sales increased by 24.7% in the second quarter of 2021 compared to the second quarter of 2020. The increase in net sales over the second quarter of 2020 was primarily driven by higher net sales in the EV/HEV, general industrial, consumer and automotive markets, partially offset by lower net sales in the mass transit market. Net sales were favorably impacted by foreign currency fluctuations of $2.5 million, or 3.5%, due to the appreciation in value of the Chinese renminbi and euro relative to the U.S. dollar.
EMS net sales increased by 16.8% in the first half of 2021 compared to the first half of 2020. The increase in net sales over the first half of 2020 was primarily driven by higher net sales in the EV/HEV, general industrial, consumer and automotive markets, partially offset by lower net sales in the mass transit market. Net sales were favorably impacted by foreign currency fluctuations of $5.2 million, or 3.4%, due to the appreciation in value of the Chinese renminbi and euro relative to the U.S. dollar.
Operating income increased by 422.1% in the second quarter of 2021 from the second quarter of 2020. As a result of the acceleration of amortization expense related to the DSP customer relationships and trademarks and trade names definite-lived other intangible assets in 2020, we recognized lower amortization expense in the second quarter of 2021 compared to the second quarter of 2020. The increase in operating income was also due to higher volume, favorable product mix, a lower inventory reserves provision and favorable absorption of fixed overhead costs. This was partially offset by higher freight, duties and tariffs expenses, higher raw material costs and unfavorable productivity performance due to raw material shortages. As a percentage of net sales, operating income in the second quarter of 2021 was 17.5%, an approximately 1,330 basis point increase as compared to the 4.2% reported in the second quarter of 2020.

32

The decrease in amortization expense for the three and six months ended June 30, 2021 was due to the acceleration of amortization expense related to our DSP customer relationships and trademarks and trade names definite-lived other intangible assets, which were both accelerated to be fully amortized by December 31, 2020 due to an adjustment to their remaining useful lives. We recognized amortization expense for our DSP definite-lived other intangible assets of $0.1 million and $4.4 million in the second quarter of 2021 and the second quarter of 2020, respectively, and $0.1 million and $4.8 million in the first half of 2021 and the first half of 2020, respectively.
Additionally, we recognized expense of $1.5 million and $2.8 million primarily related to the financial impacts from the fire at our UTIS manufacturing facility in Ansan, South Korea in 2021 for the second quarter of 2021 and the first half of 2021, respectively. This impact consisted of write-offs of fixed assets and inventory destroyed and/or damaged in the fire, professional services, costs incurred due to obligations under our manufacturing facility lease agreement, compensation and benefits for certain of our UTIS employees, partially offset by the recognition of certain anticipated insurance recoveries. There may be other potential costs that cannot be reasonably foreseen or estimated at this time and we continue to evaluate information as it becomes available. For additional information, refer to “Note 15 – Supplemental Financial Information” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q.
Our UTIS net sales were only slightly impacted by the fire at our UTIS manufacturing facility in Ansan, South Korea as a result of selling our undamaged finished goods inventory during the remainder of the first quarter of 2021. In the second quarter of 2021, we experienced a greater impact to our net sales due to the continued disruption to our UTIS operations. In the third quarter of 2021, we expect a similar impact to our net sales as the second quarter of 2021.
In the first quarter of 2021, our net sales were largely unaffected by global supply chain disruptions, but we began seeing some greater impacts as we exited the quarter. In the second quarter of 2021, the impact of supply constraints and raw material cost increases, primarily due to the weather interruptions along the U.S. Gulf Coast, somewhat tempered our net sales growth and gross margin results. In the third quarter of 2021, we expect these issues to persist, but to a lesser extent as the supply chain constraints begin to subside, in addition to commercial actions we have begun to take to address the higher raw material costs.
Our EMS operating segment incurred incremental transaction costs associated with the temporary additional benefits established under our dependent care, premium pay and sick pay programs in response to the COVID-19 pandemic, as well as additional safety supplies. These costs impacted our operating income by $0.2 million and $1.3 million in the second quarter of 2021 and the second quarter of 2020, respectively, and $0.4 million and $1.5 million in the first half of 2021 and the first half of 2020, respectively.

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

Approximately $164.6 million of our cash and cash equivalents were held by non-U.S. subsidiaries as of June 30, 2021. We did not make any changes in the six months ended June 30, 2021 to our position on the permanent reinvestment of our earnings from foreign operations. With the exception of certain of our Chinese subsidiaries, where a substantial portion of our Asia cash and cash equivalents are held, we continue to assert that historical foreign earnings are indefinitely reinvested.

Changes in key financial position accounts and other significant changes in our statements of financial position from December 31, 2020 to June 30, 2021 were as follows:
•Accounts receivable, net increased 17.1% to $157.5 million as of June 30, 2021 from $134.4 million as of December 31, 2020. The increase from year-end was primarily due to higher net sales at the end of the second quarter of 2021 compared to at the end of 2020.
•Inventories increased 8.2% to $110.8 million as of June 30, 2021, from $102.4 million as of December 31, 2020, primarily driven by raw material cost increases as well as the ramp up of raw material purchases and production efforts to meet anticipated demand.
•Borrowings under revolving credit facility were nil as of June 30, 2021 compared to $25.0 million as of December 31, 2020. This was as a result of $25.0 million of discretionary principal payments on our revolving credit facility during the first half of 2021. For additional information regarding this facility and the Fourth Amended Credit Agreement, refer to “Note 9 – Debt” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q.

As of June 30, 2021, cash and cash equivalents were $203.9 million as compared to $191.8 million as of December 31, 2020, an increase of $12.2 million, or 6.3%. This increase was primarily due to cash flows generated by operations, partially offset by $25.0 million of discretionary principal payments on our revolving credit facility during the first half of 2021, $21.4 million in capital expenditures and $2.7 million in tax payments related to net share settlement of equity awards.
In 2021, we continue to expect capital spending to be in the range of approximately $70.0 million to $80.0 million, which we plan to fund with cash from operations. This range includes the capital expenditures necessary to restore the UTIS operations, a significant portion of which we expect to be reimbursed by insurance proceeds.

Restrictions on Payment of Dividends
The Fourth Amended Credit Agreement generally permits us to pay cash dividends to our shareholders, provided that (i) no default or event of default has occurred and is continuing or would result from the dividend payment and (ii) our total net leverage ratio does not exceed 2.75 to 1.00. If our total net leverage ratio exceeds 2.75 to 1.00, we may nonetheless make up to $20.0 million in restricted payments, including cash dividends, during each fiscal year, provided that no default or event of default has occurred and is continuing or would result from the payments. Our total net leverage ratio did not exceed 2.75 to 1.00 as of June 30, 2021.
Contingencies
During the second quarter of 2021, we did not become aware of any material developments related to environmental matters disclosed in our Annual Report, our asbestos litigation or other material contingencies previously disclosed or incur any material costs or capital expenditures related to such matters. Refer to “Note 12 – Commitments and Contingencies” to the condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q for further discussion of these contingencies.

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, 2021.
