Business Combinations In March 2017, we purchased 100% of the outstanding stock of NVIS, Inc. ("NVIS") , "), a producer of virtual reality systems for 3D applications, for $3.7 million . In addition to the $3.7 million the former selling shareholders of NVIS could earn an additional $2.0 million for meeting certain operating performance milestones through March of 2020. As of December 28, 2019, we estimate that the former owners have earned approximately $1.8 million of the $2.0 million . In 2019, the Company made payments of $1.3 million to the former selling shareholders of NVIS for meeting certain operating performance milestones and the Company may be required to pay an additional $0.7 million if additional milestones are met and the selling shareholders remain employed with NVIS through March 2020. As there is a requirement to remain employed to earn the contingent payments, these contingent payments are being treated as compensation expense.
