Retirement Plans:

We have trusteed, noncontributory retirement plans for most of our full-time employees. Contributions are discretionary and amounts accrued were approximately $4.7 million, $4.2 million and $4.0 million for the years ended December 31, 2019, 2018 and 2017, respectively. Additionally, we have a trusteed, contributory retirement plan for most of our full-time employees. This plan permits employees to contribute specified percentages of their salary, matched up to a limit. Matching contributions, net of forfeitures, approximated $3.1 million, $2.6 million and $2.6 million for the years ended December 31, 2019, 2018 and 2017, respectively.

In addition, approximately 250 employees are covered by union-sponsored, multi-employer pension plans for which approximately $2.0 million, $1.8 million and $1.8 million were contributed for the years ended December 31, 2019, 2018 and 2017, respectively. We have no plans to withdraw from any of the multi-employer plans.
