PENSION BENEFITS AND RETIREMENT HEALTH AND LIFE INSURANCE BENEFITS

We have three qualified noncontributory defined benefit pension plans for unionized hourly employees, all other U.S. employees hired before December 31, 2007 and employees of the acquired Arlon business. We also have established a nonqualified unfunded noncontributory defined benefit pension plan 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 plan for certain retirees. The measurement date for all plans is December 31 for each respective plan year.

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

Defined Benefit Pension Plan Amendments and Retiree Medical Plan Amendments

During the fourth quarter of 2015, we announced that we would be changing the benefits related to the salaried and non-union hourly participants of the retirement health insurance benefits program. This program had been frozen to new participants in 2007. The 2015 amendment to the plan was approved on October 2, 2015 and resulted in a negative prior service cost, which will be amortized over the average expected remaining years of future benefit payments for this group. This change resulted in a remeasurement event requiring us to remeasure the plan liabilities, as well as the expense related to the plan, as of October 31, 2015.

All qualified noncontributory defined benefit pension plans have ceased accruing benefits. The Arlon pension plan (the "Bear Plan") was frozen previous to our acquisition of Arlon. Effective June 30, 2013, for salaried and non-union hourly employees in the U.S., and effective December 31, 2013 for union employees in the U.S., benefits under the Rogers defined benefit pension plans no longer accrue.

In the second quarter of 2013, the decision to freeze the accruing of benefits in the defined benefit pension plans resulted in a curtailment charge of $1.5 million.

In the fourth quarter of 2014, certain eligible participants in the defined benefit pension plans were given a lump sum payout offer. The payout of this program resulted in a settlement charge of $5.2 million.

The estimated net loss for the defined benefit pension plans that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the next fiscal year is $1.8 million. The estimated net benefit for the defined benefit postretirement plans that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the next fiscal year is $1.6 million.

Weighted-average assumptions used to determine benefit obligations at December 31:

Expected long-term rate of return on plan assets	6.50	%	7.50	%	—		—

Rate of compensation increase - An expected rate of compensation increase was not included in the weighted average assumptions as there would be no impact to the net benefit cost, as the plans have been previously frozen.

Discount rate - To determine the discount rate, we review current market indices of high quality corporate bonds, particularly the PruCurve index, to ensure that the rate used in our calculations is consistent and within an acceptable range based on these indices, which reflect current market conditions. The market-based rates are modified to be Rogers-specific, and this is done by applying our pension benefit cash flow projections to the generic index rate. At December 31, 2015, this analysis resulted in a 25 basis point increase to the discount rate which went from 4.00% at December 31, 2014 to 4.25% at December 31, 2015.

Long-term rate of return on assets - To determine the expected long-term rate of return on plan assets, we review historical and projected portfolio performance, the historical long-term rate of return, and how any change in the allocation of the assets could affect the anticipated returns. Adjustments are made to the projected rate of return if it is deemed necessary based on those factors and other current market trends.

Health care cost trend rates - For measurement purposes as of December 31, 2015 we assumed annual health care cost trend rates of 7.50% and 7.50% for covered health care benefits for retirees pre-age 65 and post-age 65, respectively. The rates were assumed to decrease gradually by 0.5% annually until reaching 4.50% and 4.50%, respectively, and remain at those levels thereafter. For measurement purposes as of December 31, 2014, we assumed annual health care cost trend rates of 7.50% and 7.50% for covered health care benefits for retirees pre-age 65 and post-age 65, respectively. Assumed health care cost trend rates may have a significant effect on the amounts reported for the health care plans. A one-percentage point change in assumed health care cost trend rates would have the following effects:

Plan Assets

Our defined benefit pension assets are invested with the objective of achieving a total rate of return over the long-term that is sufficient to fund future pension obligations. In managing these assets and our investment strategy, we take into consideration future cash contributions to the plans, as well as the potential of the portfolio underperforming the market, which is partially mitigated by maintaining a diversified portfolio of assets.

In order to meet our investment objectives, we set asset allocation target ranges based on current funding status and future projections in order to mitigate the risk in the plan while maintaining its funded status. In November of 2014 we implemented a pension risk reduction strategy related to our investments, which included a change in our asset mix to hold a larger amount of fixed income securities. At December 31, 2015, we held approximately 27% equity securities and 73% fixed income and short term cash securities in our portfolio, compared to December 31, 2014 when we had approximately 23% in equity securities and 77% in fixed income securities.

In determining our investment strategy and calculating the net benefit cost, we utilized an expected long-term rate of return on plan assets. This rate is developed based on several factors, including the plans' asset allocation targets, the historical and projected performance on those asset classes, and on the plans' current asset composition. To justify our assumptions, we analyze certain data points related to portfolio performance. For example, we analyze the actual historical performance of our total plan assets, which has generated a return of approximately 8.4% over the past 20 year period. Also, we analyze hypothetical rates of return for plan assets based on our current asset allocation mix, which we estimate would have generated a return of approximately, 8.5% over the last 20 years and 7.5% over the last 10 years. Based on the historical returns and the projected future returns we determined that a target return of 6.5% is appropriate for the current portfolio. Investments were stated at fair value as of the dates reported.

Securities traded on a national securities exchange are valued at the last reported sales price on the last business day of the plan year. The fair value of the guaranteed deposit account was determined through discounting expected future investment cash flow from both investment income and repayment of principal for each investment purchased.

The estimated fair values of the participation units owned by the plan in pooled separate accounts were based on quoted redemption values and adjusted for management fees and asset charges, as determined by the record keeper, on the last business day of the Plan year. Pooled separate accounts are accounts established solely for the purpose of investing the assets of one or more plans. Funds in a separate account are not commingled with other assets of the Company for investment purposes.

The following table presents the fair value of the pension plan net assets by asset category at December 31, 2015 and 2014:

Cash Flows

Contributions

At December 31, 2015, we have not met the minimum funding requirements for all of our qualified defined benefit pension plans and are therefore required to make a contribution to the Bear Plan of $0.3 million for 2015 and we estimate that we will be required to make a contribution of $0.3 million for 2016. In 2015 and 2014, we made voluntary contributions of $6.5 million and $13.0 million, respectively. As there is no funding requirement for the nonqualified defined benefit pension plans nor the Retiree Health and Life Insurance benefit plans, we fund the amount of benefit payments made during the year.

Estimated Future Payments

The following pension benefit payments are expected to be paid through the utilization of plan assets for the funded plans and from the Company's operating cash flows for the unfunded plans. The Retiree Health and Life Insurance benefits, for which no funding has been made, are expected to be paid from the Company's operating cash flows. The benefit payments are based on the same assumptions used to measure our benefit obligation at the end of fiscal 2015.
