401(k) Plan

We offer a 401(k) Plan to all employees that have reached the age of eighteen and have completed six months of service. The participants may contribute up to 100% of their salary subject to IRS limitations. Employer contributions are subject to Board discretion and are subject to a vesting schedule of 20% each year after the first year and 100% after six years. We contributed $355,000, $301,000, and $295,000 to the 401(k) Plan in 2018, 2017 and 2016, respectively.

Rented Facilities, Vehicles and Equipment

We lease certain of our facilities and equipment under operating leases with terms generally ranging from month-to-month to five years. Most leases contain renewal options. Remaining future minimum rental payments (excluding month to month) due under these leases are as follows:

2020		118
2021		97

Rent expense under such leases was $433,000, $310,000, and $325,000 for the years ended December 31, 2018, 2017 and 2016, respectively.

Legal Proceedings

From time to time, we are a party to various legal proceedings in the ordinary course of our business. While management is unable to predict the ultimate outcome of these actions, it believes that any ultimate liability arising from these actions will not have a material effect on our financial position, results of operations or cash flow. We are not currently a party to any bankruptcy, receivership, reorganization, adjustment or similar proceeding, and we are not aware of any other threatened litigation.
