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. Assetsmeasurement, including foreign currency contracts, copper derivative contracts and liabilitiesinterest rate swaps. Derivative instruments measured at fair value on a recurring basis, categorized by the level of inputs used in the valuation, included:consist of:

Note 3 – Hedging Transactions and Derivative Financial Instruments
We are exposed to certain risks related to our ongoing business operations. The primary risks being managed through our use of derivative instruments are foreign currency exchange rate risk and commodity pricing risk (primarily related to copper). During the first quarter of 2017, we also entered into an interest rate swap to hedge interest rate risk. We do not use derivative financial instruments for trading or speculative purposes. The valuation of derivative contracts used to manage each of these risks is described below:


Foreign Currency - The fair value of any foreign currency option derivative is based upon valuation models applied to current market information such as strike price, spot rate, maturity date and volatility, and by reference to market values resulting from an over-the-counter market or obtaining market data for similar instruments with similar characteristics.
Commodity - The fair value of copper derivatives is computed using a combination of intrinsic and time value valuation models. The intrinsic valuation model reflects the difference between the strike price of the underlying copper derivative instrument and the current prevailing copper prices in an over-the-counter market at period end. The time value valuation model incorporates the constant changes in the price of the underlying copper derivative instrument, the time value of money, the underlying copper derivative instrument’s strike price and the remaining time to the underlying copper derivative instrument’s expiration date from the period end date. Overall, fair value is a function of five primary variables: price of the underlying instrument, time to expiration, strike price, interest rate, and volatility.
Interest Rates - The fair value of interest rate swap instruments is derived by comparing the present value of the interest rate forward curve against the present value of the swap rate, relative to the notional amount of the swap. The net value represents the estimated amount we would receive or pay to terminate the agreements. Settlement amounts for an “in the money” swap would be adjusted down to compensate the counterparty for cost of funds, and the adjustment is directly related to the counterparties’ credit ratings.
The guidance for the accounting and disclosure of derivatives and hedging transactions requires companies to recognize all of their derivative instruments as either assets or liabilities at fair value in the statements of financial position. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies for hedge accounting treatment as defined under the applicable accounting guidance. For derivative instruments that are designated and qualify for hedge accounting treatment as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss). This gain or loss is reclassified into earnings in the same line item of the condensed consolidated statements of operations associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. 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 condensed consolidated statements of operations during the current period. As of June 30, 20172018, only our interest rate swap qualified for hedge accounting treatment as a cash flow hedge. For the six months ended June 30, 2018 and 2017, therethe hedge was hedge ineffectiveness of approximately $0.1 million which was recorded in the condensed consolidated statement of operations. For the six months ended June 30, 2016 there was no hedge ineffectiveness.highly effective.
Foreign Currency
During the quarterthree months ended June 30, 2017,2018, we entered into Korean Won, Japanese Yen, Euro, and Hungarian Forint and Chinese Renminbi forward contracts. We entered into these foreign currency forward contracts to mitigate certain global transactional exposures. These contracts do not qualify for hedge accounting treatment. As a result, any fair value adjustments required on these contracts are recorded in “Other income (expense), net” in our condensed consolidated statements of operations.
As of June 30, 20172018 the notional values of these foreign currency forward contracts were:

We currently have twenty-two25 outstanding contracts to hedge exposure related to the purchase of copper in our Power Electronics Solutions (PES) and Advanced Connectivity Solutions (ACS) operations.operating segments. These contracts are held with financial institutions and minimize the risk associated with a potential rise inare intended to offset rising copper prices. These contracts provide some coverage over the forecasted 20172018 and 20182019 monthly copper exposure and do not qualify for hedge accounting treatment. As a result, any fair value adjustments required on these contracts are recorded in “Other income (expense), net” in our condensed consolidated statements of operations.operations in the period in which the adjustment occurs.

Interest Rates
In March 2017, we entered into an interest rate swap to hedge the variable interest rate on $75.0 million of our $450.0 million revolving credit facility. This transaction has been designated as a cash flow hedge and qualifies for hedge accounting treatment. See Note 12, “Debt” for further discussion regarding the credit facility. In July 2012, we entered into an interest rate swap to hedge the variable interest rate on our previously outstanding term loan debt. This swap expired as of June 30, 2016.

Note 5 – Acquisitions
Diversified Silicone Products
On January 6, 2017, we acquired the principal operating assets of Diversified Silicone Products, Inc. (DSP), pursuant to the terms of the Asset Purchase Agreement by and among the Company, DSP and the principal shareholders of DSP (the Purchase Agreement). Pursuant to the terms of the Purchase Agreement, we acquired certain assets and assumed certain liabilities of DSP for a total purchase price of approximately $60.2 million.
We used borrowings of $30.0 million under our credit facility in addition to cash on hand to fund the acquisition.
DSP is a custom silicone product development and manufacturing business and expands the portfolio of Rogers’our Elastomeric Material Solutions business (EMS) operating segment in cellular sponge and specialty extruded silicone profile technologies, while strengthening existing expertise in precision-calendered silicone and silicone formulating and compounding.
The acquisition has been accounted for in accordance with applicable purchase accounting guidance. 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 acquired customer relationships, developed technology, trademarks, and a covenant not to compete. As of the filing date of this Form 10-Q, the final purchase accounting and purchase price allocation for the DSP acquisition are substantially complete, however, we continue to refine our preliminary valuation of certain acquired assets and the valuations below remain subject to change. The following table represents the preliminary fair market values assigned to the acquired assets and liabilities in the transaction:

Total liabilities229
  
Fair value of net assets acquired$60,191

The intangible assets consist of customer relationships valued at $30.5 million, developed technology valued at $1.8 million, trademarks valued at $3.3 million, and a covenant not to compete valued at $0.3 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 11.8 years for customer relationships, 4.3 years for developed technology, 11.7 years for trademarks, and 4.1 years for a covenant not to compete, resulting in amortization expenses


ranging from $1.1 million to $2.0 million annually. The estimated annual future amortization expense is $1.0 million for the remainder of 2017, $1.9 million for 2018, and $1.8 million for each of 2019, 2020, and 2021.
During the first six months of 2017, we incurred transaction costs of $0.5 million related to the DSP acquisition, which were recorded within selling, general and administrative expenses in the condensed consolidated statements of operations.
The results of DSP have been included in our condensed consolidated financial statements only for the periodperiods subsequent to the completion of theour acquisition on January 6, 2017, through June 30, 2017. DSP’s net sales for the three and six months ended June 30, 2017 totaled $5.4 million and $10.9 million, respectively.

DeWAL
On November 23, 2016, we acquired all of the membership interests in DeWAL Industries LLC (DeWAL), pursuant to the terms of the Membership Interest Purchase Agreement, dated November 23, 2016, by and among the Company and the owners of DeWAL for an aggregate purchase price of $135.5 million.
We used borrowings of $136.0 million under our credit facility to fund the acquisition.
DeWAL is a leading manufacturer of polytetrafluoroethylene and ultra-high molecular weight polyethylene films, pressure sensitive tapes and specialty products for the industrial, aerospace, automotive, and electronics markets.
The acquisition has been accounted for in accordance with applicable purchase accounting guidance. We recorded goodwill, primarily related to the expected synergies from combining operations and the value of the existing workforce. We also recorded intangible assets primarily related to customer relationships, developed technology, trademarks, and a covenant not to compete. As of the filing date of this Form 10-Q, the final purchase accounting and purchase price allocation for the DeWAL acquisition are substantially complete; however, we continue to refine our preliminary valuation of certain acquired assets and the valuations set forth below remain subject to change. The following table represents the preliminary fair values assigned to the acquired assets and liabilities in the transaction:

Note 8 – Stock-Based Compensation
Equity Compensation Awards
Performance-Based Restricted Stock Units
As of June 30, 2017,2018, we had performance-based restricted stock awardsunits from 2015, 2016, 2017 and 20172018 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 vestingmeasurement period. Participants are eligible to be awarded shares ranging from 0% to 200% of the original award amount, based on certain defined performance measures. Compensation expense is recognized using the straight line method over the vesting period, unless the employee has an accelerated vesting schedule.
The 20152016, 2017 and 2018 awards have twoone 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)criteria: the three year total shareholder return (TSR) on the performance of our capital stock as compared to that of a specified group of peer companies. The 2016 and 2017 awards have one measurement criteria - the three year TSR on the performance of our capital stock as compared to that of a specified group of peer companies. In accordance with the applicable accounting literature, the ROIC measurement criteria of the 2015 awards is considered a performance condition. As such, the fair value of the ROIC portion 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 measurement criteria of the awards is considered a market condition. As such, the fair value of this measurement criteria was determined on the grant date of grant using a Monte Carlo simulation valuation model, with relatedmodel. We recognize compensation expense fixed on the grant date and expensedall of these awards on a straight-line basis over the life of the awards that ultimately vest andvesting period with no changes for the final projected payout of the awards. We account for forfeitures as they occur.
Below were the assumptions used in the Monte Carlo calculation:
 June 30,
2017
 June 30,
2016
June 30, 2018 June 30, 2017
Expected volatility 33.6% 29.6%34.8% 33.6%
Expected term (in years) 3.0 3.03.0 3.0
Risk-free interest rate 1.38% 0.93%2.28% 1.38%
Expected volatility – In determining expected volatility, we have considered a number of factors, including historical volatility.
Expected term – We use the vestingmeasurement period of the award to determine the expected term assumption for the Monte Carlo simulation valuation model.
Risk-free interest rate – We use an implied “spot rate” yield on U.S. Treasury Constant Maturity rates as of the grant date for our assumption of the risk-free interest rate.


Expected dividend yield – We do not currently pay dividends on our capital stock; therefore, a dividend yield of 0% was used in the Monte Carlo simulation valuation model.
Forfeiture Rate - We previously estimated the forfeiture rate based on historical experience and our expectations regarding future terminations. To the extent our actual forfeiture rate was different from our estimate, stock-based compensation expense was adjusted accordingly. In accordance with the adoption of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, on January 1, 2017, we now account for forfeitures as they occur. The adoption of this standard, with respect to treatment of forfeitures, did not have a material impact on our condensed consolidated financial statements in the period of adoption.

The following table summarizes the change in number of non-vested performance-based restricted stock awardsunits outstanding since December 31, 2016:for the six months ended June 30, 2018:

During the three and six months ended June 30, 2018, we recognized compensation expense for performance-based restricted stock units of approximately $0.8 million and $1.8 million, respectively. During the three and six months ended June 30, 2017, we recognized compensation expense for performance-based restricted stock awardsunits of approximately $1.6 million and $1.5 million, respectively. During the three and six months ended and June 30, 2016, we recognized compensation expense for performance-based stock awards of approximately $1.4 million and $2.1 million respectively. 
Time-Based Restricted Stock Units
As of June 30, 2017,2018, we had time-based restricted stock grantsunit awards from 2013, 2014, 2015, 2016, 2017 and 20172018 outstanding. The remaining 2013 grant cliff vests on the fourth anniversary of the original grant date. The 2014, 2015, 2016, 2017 and 20172018 grants all ratably vest on the first, second and third anniversaries of the original grant date. The remaining outstanding 2014 grants cliff vest on December 17, 2018, the fourth anniversary of the original grant date. Each restricted stock unit represents a right to receive one share of the Rogers’ capital stock at the end of the vesting period. The fair value of the award is determined 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. The fair value of the award is determined based on the market value of the underlying stock price at the grant date.We account for forfeitures as they occur.

During the three and six months ended June 30, 2018 we recognized compensation expense for time-based restricted stock units of approximately $1.3 million and $2.9 million, respectively. During the three and six months ended June 30, 2017 we recognized compensation expense for time-based restricted stock awardsunits of approximately $1.7 million and $2.7 million, respectively. During the three and six months ended June 30, 2016 we recognized compensation expense for time-based restricted stock awards of approximately $1.5 million and $2.7 million, respectively.
Forfeiture Rate - We previously estimated the forfeiture rate based on historical experience and our expectations regarding future terminations. To the extent our actual forfeiture rate was different from our estimate, stock-based compensation expense was adjusted accordingly. In accordance with the adoption of ASU 2016-09 on January 1, 2017, we now account for forfeitures as they occur. The adoption of this standard, with respect to treatment of forfeitures, did not have a material impact on our condensed consolidated financial statements in the period of adoption.
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 month13-month anniversary of the grant date unless the individual elects to defer the receipt of those shares. Each deferred stock unit results in the issuance of one share of Rogers’ capital stock. The grant of deferred stock units is typically done annually during the second quarter of each year. The fair value of the award is determined based onby the market value of the underlying stock price at the grant date.


The following table summarizes the change in number of deferred stock units outstanding since December 31, 2016:during the six months ended June 30, 2018:

ForDuring each of the threethree- and six monthsix-month periods ended June 30, 20172018 and 2016,2017, we recognized compensation expense associated with the deferred stock units of $0.9 million and $0.7 million, respectively.$0.9 million.


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

Employee Stock Purchase Plan
We have an employee stock purchase plan (ESPP) that allows eligible employees to purchase, through payroll deductions, shares of our capital stock at a discount to fair market value. The ESPP has two six month offering periods each year, the first beginning in January and ending in June and the second beginning in July and ending in December. The ESPP contains a look-back feature that allows the employee to acquire shares of our capital stock at a 15% discount from the underlying market price at the beginning or end of the applicable period, whichever is lower. We recognize compensation expense on this plan ratably over the offering period based on the fair value of the anticipated number of shares that will be issued at the end of each offering period. Compensation expense is adjusted at the end of each offering period for the actual number of shares issued. Fair value is determined based on two factors: (i) the 15% discount on the underlying stock’s market value on the first day of the applicable offering period and (ii) the fair value of the look-back feature determined by using the Black-Scholes option-pricing model. We recognized approximately $0.1 million of compensation


expense associated with the plan in each of the quartersthree-month periods ended June 30, 20172018 and 20162017 and approximately $0.2 million of compensation expense associated with each of the six monthsix-month periods ended June 30, 20172018 and 2016.2017.
Note 9 – Pension Benefits and Other Postretirement Benefit Plans
We have two qualified noncontributory defined benefit pension plans: 1) the Rogers Corporation Employee’s Pension Plan for unionized hourly employees (the Union Plan); and 2) the Rogers Corporation Defined Benefit Pension Plan for (i) all other U.S. employees hired before December 31, 2007 who are salaried employees or non-union hourly employees and (ii) employees of the acquired Arlon business (the Rogers Plan).
The Company also maintains the Rogers Corporation Amended and Restated Pension Restoration Plan effective as of January 1, 2004 and the Rogers Corporation Amended and Restated Pension Restoration Plan effective as of January 1, 2005 (collectively, the Nonqualified Plans). The Nonqualified Plans serve to restore certain retirement benefits that might otherwise be lost due to limitations imposed by federal law on qualified pension plans, as well as to provide supplemental retirement benefits, for certain senior executives of the Company.
In addition, we sponsor multiple fully insured or self-funded medical plans and life insurance plans for certain retirees. The measurement date for all plans is December 31 for each respective plan year.
Pension Plan Proposed Termination
The Company currently intends to terminate the Rogers Plan and has requested a determination letter from the Internal Revenue Service (IRS). The termination of the Rogers Plan remains subject to final approval by both management and the IRS. The Company plans to provide for lump sum distributions or annuity payments in connection with the termination of the Rogers Plan and we expect the settlement process to be completed in early 2019. The Company lacks sufficient information as of June 30, 2018 to determine the financial impact of the proposed plan termination. At this time, there are no plans to terminate the Union Plan.

Employer Contributions
At December 31, 2016 we had met the minimum funding requirements for all of our qualified defined benefit pension plans due to aThere were no required contribution of $0.3 million to the pension plan that covers employees at our Bear, Delaware facility. We made required contributions of $0.1 million to our qualified defined benefit pension plans infor the firstthree and six months of 2017ended June 30, 2018, and 2016. We estimate that we will beare not required to make additional contributions of $0.2 million to these plans in 2017.
Infor the quarterremainder of 2018. We paid $0.1 million of required contributions to our qualified defined benefit pension plans for the three and six month periodsmonths ended June 30, 2017 and 2016, we did not make any2017. No voluntary contributions were made to our qualified defined benefit pension plans.plans for the three and six months ended June 30, 2018 and 2017. We anticipate making an estimated payment of $25.0 million to the Rogers Plan during the third quarter of 2018 as part of the termination process.
As there is no funding requirement for the non-qualified unfunded noncontributory defined benefit pension plan or the retiree health and life insurance benefit plans, benefit payments made during the year are funded directly by the Company.

Note 12 – Debt
On June 18, 2015, we entered into a secured five year credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (the Second Amended Credit Agreement). The Second Amended Credit Agreement provided (1) a $55.0 million term loan; (2) up to $295.0 million of revolving loans, with sublimits for multicurrency borrowings, letters of credit and swing-line notes; and (3) a $50.0 million expansion feature.
On February 17, 2017, we entered into a secured five year credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (the Third Amended Credit Agreement), which amended and restated the Second Amended Credit Agreement. The Third Amended Credit Agreement refinanced the Second Amended Credit Agreement, eliminated the term loan under the Second Amended Credit Agreement, increased the principal amount of theour revolving credit facility to up to $450.0 million borrowing capacity, with sublimits for multicurrency borrowings, letters of credit and swing-line notes, and provided an additional $175.0 million accordion feature. Borrowings may be used to finance working capital needs, for letters of credit and for general corporate purposes in the ordinary course of business, including the financing of permitted acquisitions (as defined in the Third Amended Credit Agreement).
Borrowings under the Third Amended Credit Agreement can be made as alternate base rate loans or euro-currency loans. Alternate base rate loans bear interest that includes a base reference rate plus a spread of 37.5 to 75.0 basis points, depending on our leverage ratio. The base reference rate is the greater of the prime rate; federal funds effective rate (or the overnight bank funding rate, if greater) plus 50 basis points; or adjusted 1-month LIBOR plus 100 basis points. Euro-currency loans bear interest based on adjusted LIBOR plus a spread of 137.5 to 175.0 basis points, depending on our leverage ratio.
In addition to interest payable on the principal amount of indebtedness outstanding from time to time under the Third Amended Credit Agreement, we are required to pay a quarterly fee of 20 to 30 basis points (based upon our leverage ratio) of the unused amount of the lenders’ commitments under the Third Amended Credit Agreement.
The Third Amended Credit Agreement contains customary representations, warranties, covenants, mandatory prepayments and events of default under which our payment obligations may be accelerated. If an event of default occurs, the lenders may, among other things, terminate their commitments and declare all outstanding borrowings to be immediately due and payable together with accrued interest and fees. The financial covenants include requirements to maintain (1) a leverage ratio of no more than 3.25 to 1.00, subject to an election to increase the maximum leverage ratio to 3.50 to 1.00 for one fiscal year in connection with a permitted acquisition, and (2) an interest coverage ratio of no less than 3.00 to 1.00.
All obligations under the Third Amended Credit Agreement are guaranteed by each of our existing and future material domestic subsidiaries, as defined in the Third Amended Credit Agreement (the Guarantors). The obligations are also secured by a Third Amended and Restated Pledge and Security Agreement, dated as of February 17, 2017, entered into by us and the Guarantors which grants to the administrative agent, for the benefit of the lenders, a security interest, subject to certain exceptions, in substantially all of the non-real estate assets of the Guarantors. These assets include, but are not limited to, receivables, equipment, intellectual property, inventory, and stock in certain subsidiaries.
All revolving loans are due on the maturity date, February 17, 2022. We are not required to make any quarterly principal payments under the Third Amended Credit Agreement, however, during the second quarter of 2017, we made a discretionary principal payment of $50.0 million to reduce the amount outstanding on our credit facility. Asand as of June 30, 20172018 we have $191.2$131.0 million in outstanding borrowings under our credit facility.


At June 30, 2017,2018, we have $2.8$2.0 million of outstanding deferred debtline of credit issuance costs consisting of $1.6 million related to the term loans under the Second Amended Credit Agreement and $1.2 million related to the Third Amended Credit Agreement. These coststhat will be amortized over the life of the Third Amended Credit Agreement, which will terminate in February 2022. We incurredrecorded amortization expense of $0.1 million infor each of the threethree-month periods ended June 30, 2018 and 2017, and $0.3 million and $0.2 million for the six months ended June 30, 2018 and 2017, and 2016respectively, related to these deferred costs.
In March 2017, we entered into an interest rate swap to hedge the variable interest rate on $75.0 million of our $450.0 million revolving credit facility. In July 2012, we entered into an interest rate swap to hedge the variable interest rate on our previously outstanding term loan debt. This swap expired as of June 30, 2016.


See further discussion in Note 3, “Hedging Transactions and Derivative Financial Instruments.”
Restriction on Payment of Dividends
Our Third Amended Credit Agreement generally permits us to pay cash dividends to our shareholders, provided that (i) no default or event of default has occurred and is continuing or would result from the dividend payment and (ii) our leverage ratio does not exceed 2.75 to 1.00. If our leverage ratio exceeds 2.75 to 1.00, we may nonetheless make up to $20$20.0 million in restricted payments, including cash dividends, during the fiscal year, provided that no default or event of default has occurred and is continuing or would result from the payments. Our leverage ratio did not exceed 2.75 to 1.00 as of June 30, 2017.2018.
Capital LeaseLeases
We have a capital lease obligation related to our manufacturing facility in Eschenbach, Germany. Under the terms of the leasing agreement, we have an option to purchase the property upon the expiration of the lease in 2021 at a price which is the greater of (i) the then-current market value or (ii) the residual book value of the land including the buildings and installations thereon. The total obligation recorded for the lease as of June 30, 20172018 is $5.6$5.3 million. Depreciation expense related to thethis capital lease was $0.1 million for each of the three monthsthree-month periods ended June 30, 2018 and 2017, and 2016 andwas $0.2 million for each of the six monthssix-month periods ended June 30, 20172018 and 2016. Accumulated depreciation at June 30, 2017 and December 31, 2016 was $3.6 million and $3.4 million, respectively.2017. These expenses are included as depreciation expense in cost of sales on our condensed consolidated statements of operations. Accumulated depreciation at June 30, 2018 and December 31, 2017 was $3.1 million and $3.3 million, respectively.
We also incurred interest expense on thethis capital lease of $0.1 million for each of the three monththree-month periods ended June 30, 2018 and 2017 and 2016 and $0.1 million and $0.2 million for each of the six monthsix-month periods ended June 30, 20172018 and 2016.2017. Interest expense related to the debt recorded on the capital lease is included in interest expense on the condensed consolidated statements of operations.
In 2017, we entered into two additional capital lease agreements for office related equipment in various worldwide locations. The total obligation recorded for the capital leases as of June 30, 2018 was $0.7 million. Depreciation expense related to the capital leases was $0.1 million for the three and six months ended June 30, 2018. These expenses are included as depreciation expense in selling, general and administrative expenses on the condensed consolidated statements of operations. Accumulated depreciation as of June 30, 2018 was $0.2 million.

Note 14 – Commitments and Contingencies
We are currently engaged inDescriptions of the followingprincipal environmental and legal proceedings:proceedings in which we are engaged are set forth below:
Voluntary Corrective Action Program
Our location in Rogers, Connecticut is part of the Connecticut Voluntary Corrective Action Program (VCAP). As part of this program, we partnered with the Connecticut Department of Energy and Environmental Protection (CT DEEP) to determine the corrective actions to be taken at the site related to contamination issues. We evaluated this matter and completed internal due diligence work related to the site in the fourth quarter of 2015. We recorded an accrual of $3.2 million as of December 31, 2015 for remediation costs expected to be incurred based on the facts and circumstances known to us at that time. During the third quarter of 2016, the CT DEEP approved a change to our remediation plan for the site that will reduce our overall expected costs. Accordingly, we reduced the accrual by $0.9 million as a result of a change in the level of remediation that needs to take place. This benefit was recorded as an offset to selling, general, and administrative expenses in the condensed consolidated statement of operations. Remediation activities on the site continue, totaling approximately $0.5are ongoing and are recorded as reductions to the accrual as they are incurred. We have incurred aggregate remediation costs of $0.7 million through June 30, 2017,2018, and the remaining accrual for future remediation efforts was $1.8is $1.7 million.
Superfund Sites
We are currently involved as a potentially responsible party (PRP) in one active case involving a waste disposal site, the Chatham Superfund Site. The costs incurred since inception for this claim have been immaterial and have been primarily covered by insurance policies, for both legal and remediation costs. In this matter, we have been assessed a cost sharing percentage of approximately 2% in relation to the range for estimated total cleanup costs of $18.8 million to $29.6 million. We believe we have sufficient insurance coverage to fully cover this liability and have recorded a liability and related insurance receivable of approximately $0.4 million as of June 30, 2017, which approximates our share of the low end of the estimated range. We believe we are a de minimis participant and, as such, have been allocated an insignificant percentage of the total PRP cost sharing responsibility. Based on facts presently known to us, we believe that the potential for the final results of this case having a material adverse effect on our results of operations, financial position or cash flows is remote. This case has been ongoing for many years and we believe that it will continue for the indefinite future. No time frame for completion can be estimated at the present time.
PCB Contamination
We have been working with CT DEEP and the United States Environmental Protection Agency, Region I, in connection with certain polychlorinated biphenyl (PCB) contamination at our facility in Woodstock, Connecticut. The issue was originally discovered in the soil at the facility in the late 1990s, which has been remediated. Further contamination was later found in the groundwater beneath the property, which was addressed with the installation of a pump and treat system in 2011. The future costs related to the maintenance of the groundwater pump and treat system now in place at the site are expected to be minimal. We believe that the remaining remediation activity will continue for several more years and no time frame for completion can be estimated at the present time.
PCB contamination at this facility was also found in the buildings and courtyards original to the site, in addition to surrounding areas, including an on-site pond. We have completed remediation activities for the buildings and courtyards. We currently have a reserve of $0.2 million for the pond remediation recorded in our condensed consolidated statements of financial position. We


believe this reserve will be adequate to cover the remaining remediation work related to the pond contamination based on the information known at this time. However, if additional contamination is found, the cost of the remaining remediation may increase.
Asbestos Litigation
We, like many other industrial companies, have been named as a defendant in a number of lawsuits filed in courts across the country by persons alleging personal injury from exposure to products containing asbestos. We have never mined, milled, manufactured or marketed asbestos; rather, we made and provided to industrial users a limited number of products that contained encapsulated asbestos, but we stopped manufacturing these products in the late 1980s. Most of the claims filed against us involve numerous defendants, sometimes as many as several hundred.
The following table presents information about our recentsummarizes the change in number of asbestos claims activity:outstanding during the six months ended June 30, 2018:
 
Asbestos
Claims Activity
Claims outstanding at December 31, 20162017605687
New claims filed195126
Pending claims concluded(184127)
Claims outstanding at June 30, 20172018616686
For the six months ended June 30, 2017, 1752018, 110 claims were dismissed and 917 claims were settled. Settlements totaled approximately $1.2$4.9 million for the six months ended June 30, 2017.2018.
We recognize a liability for asbestos-related contingencies that are probable of occurrence and reasonably estimable. In connection with the recognition of liabilities for asbestos related matters, we record asbestos-related insurance receivables that are deemed probable. Our estimates of asbestos-related contingent liabilities and related insurance receivables are based on an independent actuarial analysis and an independent insurance usage analysis prepared annually by third parties. The actuarial analysis contains numerous assumptions, including general assumptions regarding the asbestos-related product liability litigation environment and company-specific assumptions regarding claims rates (including diseases alleged), dismissal rates, average settlement costs and average defense costs. The insurance usage analysis considers, among other things, applicable deductibles, retentions and policy limits, the solvency and historical payment experience of various insurance carriers, the likelihood of recovery as estimated by external legal counsel and existing insurance settlements.


We review our asbestos-related forecasts annually in the fourth quarter of each year unless facts and circumstances materially change during the year, at which time we would analyze these forecasts. Currently, these analyses project liabilitiesDuring 2017, we reviewed the projections of our current and related insurance receivables over a 10-year period. It is probable we will incur additional costs for asbestos-relatedfuture asbestos claims, following this 10-yearand determined it was appropriate to extend the liability projection period but we do not believe that any related contingencies are reasonably estimable beyond such period based on, among other things, the significant proportion ofto cover all current and future claims includedthrough 2058. We based our conclusion on our history and experience with the claims data, the diminished volatility and consistency of observable claims data, the period of time that has elapsed since we stopped manufacturing products that contained encapsulated asbestos and an expectation of a downward trend in claims due to the analysisaverage age of our claimants, which is approaching the average life expectancy. As a result, we believe we are now able to make a reasonable estimate of the actuarially determined liability for current and future asbestos claims through 2058, the lag time between the date a claim is filed and its resolution. Accordingly, noexpected end of our asbestos liability (or related asset) has yet been recorded for claims that may be asserted subsequent to 2026.exposure.
As of December 31, 2016,2017, the balances of the asbestos-related claims and insurance receivables, for the 10-year projection periodwhich are projected to cover all current and future claims through 2058, were $52.0$76.2 million and $48.4$69.2 million, respectively. As of June 30, 2017, there have been no changes to these projections.
To date, the defense and settlement costs of our asbestos-related product liability litigation have been substantially covered by insurance. We have identified continuous coverage for primary, excess and umbrella insurance from the 1950s through the mid-1980s, except for a period in the early 1960s, with respect to which we have entered into an agreement for primary, but not excess or umbrella, coverage. In addition, we have entered into a cost sharing agreement with most of our primary, excess and umbrella insurance carriers to facilitate the ongoing administration and payment of claims by the carriers. The cost sharing agreement may be terminated by any party, but will continue until a party elects to terminate it. As of the filing date for this report, the agreement has not been terminated. As previously disclosed, however,During the first quarter of 2018, we received notice that primary coverage for a period of eight years and excess coverage for a period of two years had been exhausted, and as a result, we incurred indemnity and defense costs of $0.2 million and $0.5 million for the three and six months ended June 30, 2018, respectively. These costs reduced our existing asbestos-related liabilities to $75.7 million as of June 30, 2018. We expect to exhaust individual primary, excess and umbrella coverages over time, and there is no assurance that such exhaustion will not accelerate due to additional claims, damages and settlements or that coverage will be available as expected. Accordingly, while we believe it is reasonably possible that we may incur losses and defense costs in excess of our accruals in the future, we do not have sufficient data to provide a reasonable estimate or range of such losses and defense costs, at this time.
The amounts recorded for the asbestos-related liabilityliabilities and the related insurance receivables described above were based on facts known at the time and a number of assumptions. However, projecting future events, such as the number of new claims to be filed each year, the average cost of disposing of such claims, the length of time it takes to dispose of such claims, coverage issues among insurers and the continuing solvency of various insurance companies, as well as the numerous uncertainties surrounding asbestos litigation in the United States could cause the actual liability and insurance recoveries for us to be higher or lower than those projected or recorded.


There can be no assurance that our accrued asbestos liabilities will approximate our actual asbestos-related settlement and defense costs, or that our accrued insurance recoveries will be realized. We believe that it is reasonably possible that we may incur additional charges for our asbestos liabilities and defense costs in the future, which could exceed existing reserves and insurance recovery, but we are unable to estimate the amount of such additional liabilities and costs. We will continue to vigorously defend ourselves and believe we have substantial unutilized insurance coverage to mitigate future costs related to this matter.
General Litigation
In addition to the above issues, the nature and scope of our business brings us in regular contact with the general public and a variety of businesses and government agencies. Such activities inherently subject us to the possibility of litigation, including environmental and product liability matters that are defended and handled in the ordinary course of business. We have established accruals for matters for which management considers a loss to be probable and reasonably estimable. It is the opinion of management that facts known at the present time do not indicate that such litigation, after taking into account insurance coverage and the aforementioned accruals, will have a material adverse impact on our results of operations, financial position or cash flows.

Note 15 – Share RepurchaseRepurchases
On August 6, 2015, we initiated a share repurchase program (the Program) of up to $100.0 million of the Company’s capital stock. We initiated the Program to mitigate potentially dilutive effects of stock optionsoption exercises and sharesvesting of restricted stock units granted by the Company, in addition to enhancing shareholder value. The Program has no expiration date, and may be suspended or discontinued at any time without notice. As of June 30, 2017, $52.02018, $49.0 million remained available tofor repurchase under the Program.

Note 16 – Income Taxes
Our effective income tax rate was 33.9%32.6% and 71.0%33.9% for the three months ended June 30, 2018 and 2017, respectively. The decrease was primarily due to a lower U.S. effective tax rate, as a result of U.S. tax reform, and 2016, respectively.changes in pretax mix across jurisdictions with disparate tax rates, partially offset by an increase in current year accruals for uncertain tax positions. Our effective income tax rate was 33.0%23.2% and 51.2%33.0% for the six months ended June 30, 20172018 and 2016,2017, respectively. The decrease compared to the same periods in 2016, was primarily due to withholding taxes on off-shore cash movements and the changea lower U.S. effective tax rate, as a result of U.S. tax reform, changes in our assertion that certain foreign earnings are permanently reinvested recorded in 2016,pretax mix across jurisdictions with disparate tax rates, excess tax deductions on stock basedequity compensation, recognized in 2017,R&D credits and a decrease in current year accrualsrelease of reserves for uncertain tax positions, partially offset by a decreasean increase in reversal of reserves associated withcurrent year accruals for uncertain tax positions.
Historically, our intention was to permanently reinvest the majority of our foreign earnings indefinitely or to distribute them only when it was tax efficient to do so. As a result of certain internal restructuring transactions effectuated to more closely align our foreign subsidiaries from an operational, legal and geographic perspective and improve management of financial resources, with respect to offshore distributions, we modified our assertion of certain foreign subsidiary earnings considered permanently reinvested in 2016. In connection with this change, we recorded a deferred tax liability of $3.4 million associated with distribution-related foreign taxes on prior years’ undistributed earnings of certain of our Chinese subsidiaries in the second quarter of 2016. These taxes become due when distributed to other offshore subsidiaries. In addition, we incurred $5.5 million of withholding taxes related to distributions from China in the second quarter of 2016. With few exceptions, U.S. income taxes have not been provided on undistributed earnings of international subsidiaries.  We continue to intend to reinvest these earnings permanently outside the U.S. or to repatriate the earnings only when it is tax effective to do so.
The total amount of unrecognized tax benefits as of June 30, 20172018 was $6.6$12.4 million, of which $6.2$10.9 million would affect our effective tax rate if recognized. It is reasonably possible that approximately $1.6$3.6 million of our unrecognized tax benefits as of June 30, 20172018 will reverse within the next twelve months.
We recognize interest and penalties related to unrecognized tax benefits through income tax expense. As of June 30, 2017,2018, we had $0.7 million accrued for the payment of interest.
We are subject to taxation in the U.S. and various state and foreign jurisdictions. With few exceptions, we are no longer subject to examinations by tax authorities for years prior to 2012.2013.
We adopted ASU 2016-09 on January 1, 2017. Upon adoption, we recognized excess tax benefits of approximately $12.7 million in deferred tax assets that were previously not recognized in a cumulative-effect adjustment to retained earnings. In addition, the new guidance requires that all of the tax effects related to share-based payments at settlement or expiration be recorded through the statement of operations which resulted in the recognition of $0.5 million and $1.6 million of income tax benefits during the three and six months ended June 30, 2017, respectively. See Note 19 - “Recent Accounting Standards” for further information.



Note 17 – Restructuring and Impairment Charges
Global Headquarters Relocation
In the second quarter of 2017, we completed the physical relocation of our global headquarters from Rogers, Connecticut to Chandler, Arizona. The move builds upon our presence in Arizona, where we have major business and manufacturing operations. The move supports our long-term strategy and is an integral part of our plans for growth and expansion. The new global corporate headquarters location is home to approximately 70 employees who support areas such as human resources, information technology, finance and supply chain, among others. The Rogers, Connecticut location continues to have manufacturing, research and development and support services. We recorded $1.1$0.1 million and $1.8$1.1 million of expense related to this project in the three months ended June 30, 2018 and 2017, respectively and $0.5 million and $1.8 million in the six months ended June 30, 2017.2018 and 2017, respectively. Severance activity related to the headquarters relocation is presented in the table below for the six months ended June 30, 2017:2018:

The fair value of the total severance benefits to be paid (including payments already made) in connection with the relocation is $1.1 million, of which we expensed $0.0 million and $0.1 million in the three months ended June 30, 2018 and 2017, respectively and $0.1 million and $0.3 million in the six months ended June 30, 2018 and 2017, respectively. The total severance costs are being expensed ratably over the required service period for the affected employees.


Facility Consolidation
On April 24, 2018, we made the decision to relocate our Santa Fe Springs, California operations to the Company’s facilities in Carol Stream, Illinois and Bear, Delaware. We expect to incur restructuring expenses of approximately $2.0 million in connection with the closure and transfer of production capabilities to the Carol Stream, Illinois and Bear, Delaware facilities. These costs include approximately $0.8 million in severance and retention expenses and $1.2 million of costs related to the relocation of equipment. The Company estimates that approximately $1.5 million and $0.5 million of the costs will be incurred in fiscal years 2018 and 2019, respectively.Completion of the transfer, and start-up of production at the Carol Stream, Illinois and Bear, Delaware facilities, is expected to require capital expenditures of approximately $1.2 million to $1.4 million. We recorded $0.5 million of expense related to this project in the three and six months ended June 30, 2018, respectively. Severance activity related to the facility consolidation is presented in the table below for the six months ended June 30, 2018:

Note 18 – Assets Held for Sale
In the second quarter of 2017, we began actively marketing for sale unutilized property in Chandler, Arizona, consisting of a building and two adjacent parcels of land with an aggregate net book value of $0.9 million. In the second quarter of 2018, we completed the sale of the building and one parcel of land and recognized a gain on sale of approximately $0.4 million in operating income. The remaining parcel of land being classified as held for sale has a net book value of $0.4 million.
Note 19 – Revenue from Contracts with Customers
Revenue Recognition
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, to achieve a consistent application of revenue recognition, resulting in a single revenue model to be applied by reporting companies under U.S. generally accepted accounting principles. Under the new model, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the providing entity expects to be entitled in exchange for those goods or services. In addition, the new standard requires that reporting companies disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.
We recognize revenue when all of the following criteria are met: (1) we have entered into a binding agreement, (2) the performance obligations have been identified, (3) the transaction price to the customer has been determined, (4) the transaction price has been allocated to the performance obligations in the contract, and (5) the performance obligations have been satisfied. The majority of our shipping terms permit us to recognize revenue at point of shipment. Some shipping terms require the goods to be through customs or be received by the customer before title passes. In those instances, revenue is not recognized until either the customer has received the goods or they have passed through customs, depending on the circumstances. Shipping and handling costs are treated as fulfillment costs. Sales tax or VAT are excluded from the measurement of the transaction price.
The Company manufactures some products to customer specifications which are customized to such a degree that it is unlikely that another entity would purchase these products or that we could modify these products for another customer. These products are deemed to have no alternative use to the Company whereby we have an enforceable right to payment evidenced by contractual termination clauses. In accordance with ASC 606, for those circumstances we recognize revenue on an over-time basis. Revenue recognition does not occur until the product meets the definition of “no alternative use” and therefore, items that have not yet reached that point in the production process are not included in the population of items with over-time revenue recognition.
As appropriate, we record estimated reductions to revenue for customer returns, allowances, and warranty claims. Provisions for such reductions are made at the time of sale and are typically derived from historical trends and other relevant information.
Performance Obligations
Manufactured goods are our primary performance obligations. Revenue related to our performance obligations is predominantly recognized at a point in time consistent with our shipping terms. For certain products that meet the criteria of no alternative use whereby the Company has the right to payment, we recognize revenue on an over-time basis.


The selection of a method to measure progress toward completion of a contract requires judgment and is based on the nature of the products or services to be provided. We use the cost incurred method to measure the progress of our contracts with no alternative use products whereby the Company has the right to payment as we believe it is the best depiction of the transferring of value to the customer. Under the cost incurred method, the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the contract. Contract costs include labor, materials and subcontractors costs, as well as an allocation of indirect costs. Revenues, including estimated fees or profits, are recorded as costs are incurred.
Performance obligations are typically satisfied within three months of receipt of a customer order; therefore, a change in cost estimates will not have a material impact on the percentage of completion noted at the prior quarter end. Our typical payment terms with customers range from 30 days to 105 days. Product pricing is determined and negotiated on a standalone basis. Product pricing is determined without consideration for the pricing, margin, or other information specific to other products that the same customer or other parties related to that customer may also purchase, whether in the same or a different contract. Management allocates the transaction price to its performance obligations primarily based on stand-alone selling prices that may have been developed via specific customer quote for no alternative use products and non-standard products or standard price lists for standard products. The accounting for the estimate of variable consideration is consistent with our current practice.
Contract modifications occur when there is a change to the products, price, or both. Contract modifications are treated as a separate contract if there are additions to promised goods and services that are distinct and if the price for that separate performance obligation reflects the stand-alone selling price for those goods or services. However, if the obligations in the contract modification are not distinct and are part of a single performance obligation that is only partially satisfied, the contract is not determined to be a separate contract and is accounted for as a revision to an existing contract. These modifications are accounted for prospectively when remaining promises are distinct from those previously transferred, or through a cumulative catch-up adjustment.
Contract Balances
The Company has contract assets primarily related to unbilled revenue for revenue recognized related to products that are deemed to have no alternative use whereby we have the right to payment. Revenue is recognized in advance of billing to the customer in these circumstances as billing is typically performed at the time of shipment to the customer. The unbilled revenue is included in the contract assets on the condensed consolidated statements of financial position.
The Company did not have any contract liabilities as of June 30, 2018.
The following table presents contract assets by operating segment as of June 30, 2018:

No impairment losses were recognized during the three and six months ended June 30, 2018 on any receivables or contract assets arising from our contracts with customers.
Transition
We adopted ASU 2014-09 in the first quarter of 2018 retrospectively with the cumulative effect of applying the standard recognized at the date of implementation and without restatement of comparative periods. This application of the new standard resulted in an increase to the January 1, 2018 balance of retained earnings of approximately $4.2 million, net of tax.
The guidance was applied to all contracts that were not completed at the date of implementation. The primary reason for the impact of adoption is due to over-time revenue recognition.
If the criteria for over-time recognition are not met, revenue is recognized at a point in time. In considering at what point in time control of the product or service has transferred to the customer, we consider qualitative factors such as: 1) present right to payment; 2) legal title to the asset; 3) physical possession; 4) risks and rewards of ownership; and, 5) customer acceptance.


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

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

Also in the first quarter of 2017, we began actively marketing for sale a facility in Belgium with a net book value of $1.8 million. The asset is classified as held for sale as of June 30, 2017 and is no longer being depreciated. We have an agreement to sell this property and expect to close on the sale in the second half of 2017.
In the second quarter of 2017, we began actively marketing for sale unutilized property in the U.S. consisting of a building and an adjacent parcel of land with a net book value of $0.9 million. The asset is classified as held for sale as of June 30, 2017 and is no longer being depreciated.
As both the Belgian and U.S. facilities held for sale are expected to be sold within the next twelve months, they have been classified as current.

Note 1921 – Recent Accounting Standards
In March 2018, the Financial Accounting Standards Board (FASB) issued ASU No. 2018-05, Income Taxes (Topic 740):Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. This ASU adds guidance that answers questions regarding how certain income tax effects from the Tax Cuts and Jobs Act (the Act) should be applied to companies’ financial statements. The guidance also lists which financial statement disclosures are required under a measurement period approach.
In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows for reclassification of stranded tax effects resulting from the Act from accumulated other comprehensive income to retained earnings. This ASU is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the method and impact the adoption of ASU 2018-02 will have on the Company’s consolidated financial statements and disclosures.
In January 2018, the FASB released guidance on the accounting for tax on the Global Intangible Low Tax Income (GILTI) provisions of the Act. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or to treat any taxes on GILTI inclusions as period costs are both acceptable methods subject to an accounting policy election. Effective in the first quarter of 2018, the Company has elected to treat any potential GILTI inclusions as a period cost.


In December 2017, Staff Accounting Bulletin No. 118 (SAB 118) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, we recorded provisional estimates for the deferred tax expense recorded in connection with the remeasurement of certain deferred tax assets and tax expense associated with the mandatory deemed repatriation of foreign earnings at December 31, 2017. Management has continued to gather and analyze information associated with these provisional estimates and did not record any adjustments during the three and six months ended June 30, 2018. Any subsequent adjustment to these amounts will be recorded to tax expense in the quarter of 2018 when the analysis is complete.
In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. ASU No. 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017. Adoption of this standard will be applied prospectively to awards modified on or after the adoption date. The impact of this new standard will depend on the extent and nature of future changes to the terms and conditions of the Company’s share-based payment awards. Historically, theThe Company hasadopted this standard on January 1, 2018, which did not had significant changes to its share-based payment awards and therefore does not expect adoption of this guidance to have a material effect on the condensed consolidated financial statements upon its adoption in 2018.statements.
In March 2017, the FASB issued ASU No. 2017-05 and ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost. The changes to the standard require employers to report the service cost component in the same line item as other compensation costs arising from services rendered by employees during the reporting period. The other components of net periodic pension benefit costs will be presented in the statement of operations separately from the service cost and outside of a subtotal of operating income from operations. In addition, only the service cost component may be eligible for capitalization where applicable. ASU No. 2017-05 and ASU 2017-07 arebecame effective for annual periods beginning after December 15, 2017. The Company expects to adoptadopted this guidance when effective andstandard on January 1, 2018. In conjunction with the adoption is not expected to have a material effect on the financial statements.
In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, in an effort to simplify the subsequent measurement of goodwill and the associated procedures to determine fair value. The amendments of this ASU are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted, however, the Company has not yet determined if it will adopt prior to 2020. The adoption of this guidance, is not expected to have a material impact on our financial statements.


In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, with the intention to reduce diversity in practice, as well as simplify elements of classification within the statement of cash flows for certain transactions. The update was effective for interim and annual reporting periods beginning after December 15, 2016. The accounting update was to be adopted using a retrospective approach. The Company adopted ASU 2016-15 effective January 1, 2017, and it did not have a material impact on our financial statements.
In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, which contains amendments intended to simplify various aspects of share-based payment accounting and presentation in the financial statements, including the income tax consequences, classification of awards as either equity or liabilities, treatment of forfeitures and statutory tax withholding requirements, and classification in the statement of cash flows. The update was effective for interim and annual reporting periods beginning after December 15, 2016. The new standard required a modified retrospective transition through a cumulative-effect adjustment as of the beginning of the period of adoption, with certain provisions requiring either a prospective or retrospective transition. The Company adopted ASU 2016-09 on January 1, 2017. Upon adoption, the Company recognized excess tax benefits of approximately $12.7reclassified $0.4 million and $0.8 million in deferred tax assets that were previously not recognized in a cumulative-effect adjustmentnet periodic pension benefits from Selling, general and administrative expenses to retained earnings. In addition,Other income (expense), net for the new guidance requires that all of the tax effects related to share-based payments at settlement or expiration be recorded through the statement of operations. The Company also adopted the standard with respect to treatment of forfeitures, which did not have a material impact on our financial statements.three and six months ended June 30, 2017, respectively.
In February 2016, the FASB issued ASU No. 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to classify leases as either finance or operating leases and record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. An accounting policy election may be made to account for leases with a term of 12 months or less similar to existing guidance for operating leases today. ASU No. 2016-02 supersedes the existing guidance on accounting for leases. The standard is effective for interim and annual reporting periods for fiscal years beginning after December 15, 2018. Early adoption of this standard is permitted and it is to be adopted using a modified retrospective approach. The Company has initiated its implementation plan, which includesestablished an inventory of existing leases and is in the process of evaluating the classification of oureach lease agreements and quantifying the accounting impact in accordance with the new accounting standard. The Company expects to adopt this accounting standard beginning in fiscal year 2019.
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, 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.
Note 22 – Subsequent Events
Acquisition
On July 9, 2015,6, 2018, we acquired 100% of the FASB agreedmembership interests of Griswold LLC (Griswold), a leading manufacturer of a wide range of high-performance engineered cellular elastomer and microcellular polyurethane products and solutions, for a cash-free, debt-free purchase price of $77.9 million plus an earn-out capped at $3.0 million based on certain of Griswold’s 2018 product sales. We used $82.5 million in borrowings under our existing credit facility to delayfund the effective date by one year. In accordance withtransaction. Griswold, headquartered in Moosup, Connecticut, sells to customers across the agreed upon delay,automotive, transportation, medical, office products, printing and electronics industries.
Due to the updated standard is effectivetiming of the acquisition, disclosures relating to the acquisition, including the allocation of the purchase price, have been omitted because the initial accounting for us beginning in the first quartertransaction was incomplete as of 2018. Early adoption is permitted, but not before the original effectivefiling date of the standard. During 2016, the FASB issued new accounting standards updates regarding principal versus agent considerations in determining revenue recognition identifying performance obligations and licensing, collectability, sales tax, non-cash considerations, completed contracts, contract modifications and effect of accounting change. During 2017, the FASB issued new accounting standards updates regarding clarification of determining the customer in a service concession arrangement. 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. The Company plans to adopt this standard retrospectively with the cumulative effect approach; however, the Company will continue to evaluate its options as the implementation process continues. The Company has established a cross-functional coordinated implementation team and engaged a third party service provider to assist with the project. The Company is completing its evaluation of contracts and is in the process of quantifying the financial impact of the new standard. The Company is also evaluating and implementing changes to its systems, processes and internal controls, as necessary, to meet the reporting and disclosure requirements. At this stage of the process, the Company has not yet determined if the adoption of the new standard will have a material impact on its consolidated financial statements and disclosures.report.

In the following discussion and analysis, we sometimes provide financial information that was not prepared in accordance with U.S. generally accepted accounting principles (GAAP). Management believes that this non-GAAP information provides meaningful supplemental information regarding the Company’s performance by excluding certain expenses that are generally non-recurring or otherwise may not be indicative of the core business operating results. In general, the Company believes that the additional non-GAAP financial information provided herein is useful to management and investors in assessing the Company’s historical performance and for planning, forecasting and analyzing future periods. However, non-GAAP information has limitations as an analytical tool and should not be considered in isolation from, or solely as an alternative to, financial information prepared in accordance with GAAP. Any time we provide non-GAAP information in the following narrative we identify it as such and in close proximity provide the most directly comparable GAAP financial measure, as well as the information necessary to reconcile the two measures.

Our effective income tax rate was 33.9%32.6% and 71.0%33.9% for the three months ended June 30, 2018 and 2017, respectively. The decrease was primarily due to a lower U.S. effective tax rate, as a result of U.S. tax reform, and 2016, respectively.changes in pretax mix across jurisdictions with disparate tax rates, partially offset by an increase in current year accruals for uncertain tax positions. Our effective income tax rate was 33.0%23.2% and 51.2%33.0% for the six months ended June 30, 20172018 and 2016,2017, respectively. The decrease compared to the same periods in 2016, was primarily due to withholding taxes on off-shore cash movements and the changea lower U.S. effective tax rate, as a result of U.S. tax reform, changes in our assertion that certain foreign earnings are permanently reinvested recorded in 2016,pretax mix across jurisdictions with disparate tax rates, excess tax deductions on stock basedequity compensation, recognized in 2017R&D credits and a decrease in current year accrualrelease of reserves for uncertain tax positions, partially offset a decreaseby an increase in reversal of reserves associated withcurrent year accruals for uncertain tax positions.
Historically, our intention was to permanently reinvest the majority of our foreign earnings indefinitely or to distribute them only when it was tax efficient to do so. As a result of certain internal restructuring transactions effectuated to more closely align our foreign subsidiaries from an operational, legal and geographic perspective and improve management of financial resources, with respect to offshore distributions, we modified our assertion of certain foreign subsidiary earnings considered permanently reinvested in 2016. In connection with this change, we recorded a deferred tax liability of $3.4 million associated with distribution-related foreign taxes on prior years’ undistributed earnings of certain of our Chinese subsidiaries in the second quarter of 2016. These taxes become due when distributed to other offshore subsidiaries. In addition, we incurred $5.5 million of withholding taxes related to distributions from China in the second quarter of 2016. With few exceptions, U.S. income taxes have not been provided on undistributed earnings of international subsidiaries.  We continue to intend to reinvest these earnings permanently outside the U.S. or to repatriate the earnings only when it is tax effective to do so.

There were no material changesRevenue Recognition
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, to achieve a consistent application of revenue recognition, resulting in a single revenue model to be applied by reporting companies under U.S. generally accepted accounting principles. With the adoption of ASU 2017-09, we recognize revenue when all of the following criteria are met: (1) we have entered into a binding agreement, (2) the performance obligations have been identified, (3) the transaction price to the customer has been determined, (4) the transaction price has been allocated to the performance obligations in the contract, and (5) the performance obligations have been satisfied. The majority of our critical accounting policies duringshipping terms permit us to recognize revenue at point of shipment. Some shipping terms require the second quartergoods to be through customs or be received by the customer before title passes. In those instances, revenue is not recognized until either the customer has received the goods or they have passed through customs, depending on the circumstances. Shipping and handling costs are treated as fulfillment costs. Sales tax or VAT are excluded from the measurement of 2017.
