In July 2017, in conjunction with the Spectrum Acquisition, the Board of Directors engaged one of the Company’s independent directors to serve as the chairperson of the Spectrum Integration Committee. In this role, this Director worked directly with the Company’s executive team on general integration strategy and focused on the integration of Spectrum’s operations and commercial organization with the Company. The Company recorded $0.2 million of expense for the year ended December 31, 2017 related to this director’s services.

Additionally, certain facilities leased by Spectrum are owned by Roy Eddleman, the former owner of Spectrum. As of December 31, 2019, Mr. Eddleman owned greater than

% of the Company’s outstanding shares and the Company considers him to be a related party. The lease amounts paid to this shareholder prior to the public offering were negotiated in connection with the Spectrum Acquisition. The Company incurred rent expense totaling $

0.7

million for the year ended December 31, 2019 related to these leases.

As part of the Spectrum Acquisition, the Company was responsible for filing all tax returns for Spectrum for the period from January 1, 2017 through July 31, 2017, the day before the Spectrum Acquisition. The Company was responsible for collecting any tax refunds from federal and state authorities and remitting these refunds to the former shareholders of Spectrum, including the former owner of Spectrum who held more than 5% of the

Company’s outstanding common stock prior to May 3, 2019. During 2018, the Company collected $1.7 million of these tax refunds, which the Company paid to the Spectrum shareholders during the fourth quarter of 2018, net of $0.2 million of expenses paid by the Company on behalf of Spectrum for tax preparation and other fees.
