Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	16. COMMITMENTS AND CONTINGENCIES The Company has obligations related to commitments to purchase certain goods. As of June 26, 2020, such obligations were $145,622 for the rest of fiscal year 2020 and $2,850 for fiscal year 2021 and beyond. These amounts represent open purchase orders for materials used in production. Legal Contingencies —The Company is a defendant in a number of pending legal proceedings, some of which were inherited from its former parent, Tyco International Ltd. ("Tyco"), including certain product liability claims. Several lawsuits have been filed against the Company and the Company has also received other claim demand letters alleging that the Company's anti-microbial coated steel sprinkler pipe, which the Company has not manufactured or sold for several years, is incompatible with chlorinated polyvinyl chloride and caused stress cracking in such pipe manufactured by third parties when installed together in the same sprinkler system, which the Company refers to collectively as the "Special Products Claims." After an analysis of claims experience, the Company reserved its best estimate of the probable and reasonably estimable losses related to these matters. The Company's total product liability reserves for Special Products Claims and other product liability matters were $823 and $2,424 as of June 26, 2020 and September 30, 2019, respectively. As of June 26, 2020, the Company believes that the range of aggregate reasonably possible losses for Special Products Claims and other product liabilities is between $1,000 and $8,000. During fiscal 2019, Tyco and the Company agreed with a plaintiff to settle one Special Products Claim that was to go to trial. The Company agreed to fund the total settlement in exchange for Tyco's agreement to cap the Company's Special Products Claim deductible at $12,000, as opposed to the $13,000 cap negotiated within the original indemnity agreement. In conjunction with the payment of that settlement, Tyco and the Company examined the Company's total Special Products Claim payments and agreed that with that settlement payment and payment of a few other legal fee invoices, all of which have now been paid, the Company had met its $12,000 deductible obligation related to these Special Products Claims. Tyco, now Johnson Controls, Inc. ("JCI"), has a contractual obligation to indemnify the Company in respect of all remaining and future claims of incompatibility between the Company's antimicrobial coated steel sprinkler pipe and CPVC pipe used in the same sprinkler system. Tyco has defended and indemnified the Company on Special Products Claims as required. At this time, the Company does not expect the outcome of the Special Products Claims proceedings, either individually or in the aggregate, to have a material adverse effect on its business, financial condition, results of operations or cash flows, and the Company believes that its reserves are adequate for all remaining contingencies for Special Products Claims. During the nine months ended June 26, 2020, one of the Company’s manufacturing facilities experienced a flood which resulted in damages to certain property, plant and equipment. This facility is covered under the Company’s property and casualty loss and business interruption insurance policies. The Company is currently in the process of finalizing its estimates related to the property, plant and equipment losses incurred. The range of loss is currently estimated to be between $6,046 and $13,000. This range excludes any amounts related to business interruption losses. The Company believes that, other than the $1,000 deductible expense under the related insurance claim, it will be reimbursed for substantially all other property, plant and equipment losses in connection with the event under its current insurance policies. The Company has recorded an estimated loss of $1,486 with a related insurance recovery of $1,486 within selling, general and administrative expenses in its condensed consolidated statements of operations for the three months ended June 26, 2020. The Company has recorded an estimated loss of $6,046 with a related insurance recovery of $5,046 within selling, general and administrative expenses in its condensed consolidated statements of operations for the nine months ended June 26, 2020. In addition to the matters discussed above, from time to time, the Company is subject to a number of disputes, administrative proceedings and other claims arising out of the ordinary conduct of the Company's business. These matters generally relate to disputes arising out of the use or installation of the Company's products, product liability litigation, contract disputes, patent infringement accusations, employment matters, personal injury claims and similar matters. On the basis of information currently available to the Company, it does not believe that existing proceedings and claims will have a material adverse effect on its business, financial condition, results of operations or cash flows. However, litigation is unpredictable, and the Company could incur judgments or enter into settlements for current or future claims that could adversely affect its business, financial condition, results of operations or cash flows.
