Legal Proceedings On February 10, 2017, the Company received an unfavorable judgment related to a trademark infringement case, which the Company is still in the process of challenging. In connection with this ongoing dispute, the Company recorded a $6.2 million expense accrual during the fourth quarter of fiscal year 2016, which is reported in Selling, general and administrative expenses on the consolidated statement of operations. During fiscal year 2017, the Company recorded a $2.8 million reversal of a portion of this legal expense accrual, as a result of an amended judgement reducing the initial damages awarded in the trademark infringement dispute. There are various claims, lawsuits and pending actions against the Company arising in the normal course of the Companys business. It is the opinion of management that the ultimate resolution of these matters will not have a material effect on the Companys financial condition, results of operations or cash flows.
