Rent expense was approximately $0.1 million, $0.2 million and $0.4 million during fiscal years 2017, 2016 and 2015, respectively. Legal Proceedings The Company is involved in various pending legal actions in the ordinary course of its business. Management is unable to predict the ultimate outcome of these actions, because of the inherent uncertainty of litigation. However, management believes that the most probable, ultimate resolution of current pending matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.
