Employee Savings and Investment Plans | EMPLOYEE SAVINGS AND INVESTMENT PLANS We sponsor the Rogers Employee Savings and Investment Plan (RESIP), a 401(k) plan for domestic employees. Employees can defer an amount they choose, up to the yearly IRS limit of $18,000. Certain eligible participants are also allowed to contribute the maximum catch-up contribution per IRS regulations. Our matching contribution is 6% of an eligible employee’s annual pre-tax contribution at a rate of 100% for the first 1% and 50% for the next 5% for a total match of 3.5%. Unless otherwise indicated by the participant, the matching dollars are invested in the same funds as the participant’s contributions. RESIP related expense amounted to $4.0 million in 2017, $3.0 million in 2016 and $3.2 million in 2015, which related solely to our matching contributions. We acquired DSP in January 2017 and eligible DSP employees were included in the RESIP as of the third quarter of 2017. Compensation expense related to the additional DSP employees was de minimis in 2017. We acquired DeWAL in November 2016. Eligible DeWAL employees are covered under the DeWAL Industries, Inc. 401k Profit Sharing Plan (DeWAL Plan). The DeWAL Plan matching contribution is 100% of the first 3% of employee pre-tax contributions. Compensation expense related to the DeWAL Plan was de minimis in 2017 and for the period in 2016 subsequent to the acquisition.
