Telos ID matches one-half of employee contributions to the Plan up to a maximum of 2% of such employee's eligible annual base salary. Telos ID's matching contributions to the Telos ID Plan were suspended for 2015. The total 2017, 2016, and 2015 Telos ID contributions to this plan were $105,000, $96,000, and $0, respectively.
