Company Retirement Plans | Note 16—Company Retirement Plans Defined Contribution Plans—We sponsor multiple defined contribution plans for eligible employees not covered by collective bargaining agreements. Our plans include various features such as voluntary employee pre-tax and Roth-based contributions and matching contributions made by us. In addition, at the discretion of our Board of Directors, we may make additional profit share contributions to the plans. No such additional contributions were made during 2016 through 2018. Matching contributions to all defined contribution plans for the years ended December 31, 2018, 2017 and 2016 were $4.6 million, $4.2 million, and $4.0 million, respectively. The increase in contributions in 2018 is primarily due to the acquisition of Willbros. We have no other post-retirement benefits.
