6. Commitments and Contingencies : The Company self-insures its product liability, automotive, workers' compensation, and general liability losses up to $250 per occurrence. Catastrophic coverage has been purchased from third party insurers for occurrences in excess of $250 up to $60,000 . The two risk areas involving the most significant accounting estimates are workers' compensation and automotive liability. Actuarial valuations performed by the Company's outside risk insurance expert were used by the Company's management to form the basis for workers' compensation and automotive liability loss reserves. The actuary contemplated the Company's specific loss history, actual claims reported, and industry trends among statistical and other factors to estimate the range of reserves required. Risk insurance reserves are comprised of specific reserves for individual claims and additional amounts expected for development of these claims, as well as for incurred but not yet reported claims. The Company believes that the liability of approximately $1,968 recorded for such risks is adequate as of September 28, 2019 . As of September 28, 2019 , the Company has provided certain vendors and insurers letters of credit aggregating $11,736 related to our product purchases and insurance coverage for product liability, workers compensation, and general liability. The Company self-insures group health claims up to an annual stop loss limit of $250 per participant. Historical group insurance loss experience forms the basis for the recognition of group health insurance reserves. Provisions for losses expected under these programs are recorded based on an analysis of historical insurance claim data and certain actuarial assumptions. The Company believes that the liability of approximately $2,162 recorded for such risks is adequate as of September 28, 2019 . The Company imports large quantities of fastener products which are subject to customs requirements and to tariffs and quotas set by governments through mutual agreements and bilateral actions. The Company could be subject to the assessment of additional duties and interest if it or its suppliers fail to comply with customs regulations or similar laws. The U.S. Department of Commerce (the "Department) has received requests from petitioners to conduct administrative reviews of compliance with anti-dumping duty and countervailing duty laws for certain nails products sourced from Asian countries. The Company sourced products under review from vendors in China and Taiwan during the periods selected for review. The Company accrues for the duty expense once it is determined to be probable and the amount can be reasonably estimated. On March 16, 2018, the Department published updated results, which were finalized upon the completion of review of appeals in April 2018. Based on the final results, our liability was reduced to $2,146 at March 31, 2018 from $6,274 at December 30, 2017. The Company recorded income of $0 and $4,128 in the thirteen and thirty-nine weeks ended September 29, 2018 , which is included in Cost of Goods Sold on the Condensed Consolidated Statement of Comprehensive Loss. There were no related charges in the thirteen and thirty-nine weeks ended September 28, 2019 . On June 3, 2019, The Hillman Group, Inc. ("Hillman Group") filed a complaint for patent infringement against KeyMe, Inc., a provider of self-service key duplication kiosks, in the United States District Court for the Eastern District of Texas (Marshall Division). Hillman Groups complaint alleges that KeyMes self-named and Locksmith in a Box key duplication kiosks infringe U.S. Patent Nos. 8,979,446 and 9,914,179, which are assigned to Hillman Group, and seeks damages and injunctive relief against KeyMe. After the United States Patent and Trademark Office issued U.S. Patent No. 10,400,474 to Hillman Group on September 3, 2019, Hillman Group filed a motion the same day to amend its initial complaint to add the new patent to the litigation. The Texas court granted the motion on September 13, 2019. KeyMe filed two motions in the case on July 25, 2019, the first seeking to dismiss Hillman Group's complaint under Rule 12(b)(3) of the Federal Rules of Civil Procedure for improper venue, or in the alternative, to move the case from Marshall, Texas to the Southern District of New York. KeyMes second motion seeks to transfer the venue of the case from Texas to New York under 28 U.S.C.  1404. Briefing was completed on these motions on September 25, 2019, and they await a decision from the Texas court. On August 16, 2019, KeyMe filed a complaint for patent infringement against Hillman Group in the United States District Court for the District of Delaware. KeyMe alleges that Hillmans KeyKrafter key duplication machines and MinuteKey self-service key duplication kiosks infringe KeyMes U.S. Patent No. 8,682,468 when those machines are used in conjunction with Hillmans KeyHero system. KeyMe seeks damages and injunctive relief against Hillman. Hillman filed an answer to KeyMes complaint on October 23, 2019, and asserted counterclaims seeking declaratory judgments of invalidity and noninfringement of U.S. Patent No. 8,682,468. Management and legal counsel for the Company are of the opinion that the plaintiffs claim is without merit and the Company should prevail in defending the suit. The Company is unable to estimate the possible loss or range of loss at this early stage in the case. In addition, legal proceedings are pending which are either in the ordinary course of business or incidental to the Company's business. Those legal proceedings incidental to the business of the Company are generally not covered by insurance or other indemnity. In the opinion of the Company's management, the ultimate resolution of the pending litigation matters will not have a material adverse effect on the consolidated financial position, operations, or cash flows of the Company.
