Such indemnification clauses may not be subject to maximum loss clauses. The Company has also entered into indemnification agreements with its officers and directors. No material amounts were reflected in the Company’s consolidated financial statements for the years ended December 31, 2018, 2017 or 2016 related to these indemnifications.
