Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Pension Freeze Effective December 31, 2015, the Company's qualified pension plan was frozen with respect to future benefit accruals. Under USG Cost Accounting Standard (“CAS”) 413 the Company must determine the USG’s share of any pension curtailment adjustment calculated in accordance with CAS. Such adjustments can result in an amount due to the USG for pension plans that are in a surplus position or an amount due to the contractor for plans that are in a deficit position. During the fourth quarter of 2016, the Company accrued a $0.3 million liability representing its estimate of the amount due to the USG based on the Company's pension curtailment adjustment calculation, which was submitted to the USG for review in December 2016. The Company has maintained its accrual at $0.3 million as of June 29, 2018. There can be no assurance that the ultimate resolution of this matter will not have a material adverse effect on the Company's results of operations, financial position and cash flows. New Hartford Property In connection with the sale of the Company’s Music segment in 2007, the Company assumed responsibility for meeting certain requirements of the Connecticut Transfer Act (the “Transfer Act”) that applied to the transfer of the New Hartford, Connecticut, facility leased by that segment for guitar manufacturing purposes (“Ovation”). Under the Transfer Act, those responsibilities essentially consist of assessing the site's environmental conditions and remediating environmental impairments, if any, caused by Ovation's operations prior to the sale. The site is a multi-tenant industrial park, in which Ovation and other unrelated entities lease space. The environmental assessment process, which began in 2008, has been completed and site remediation is in process. 13. COMMITMENTS AND CONTINGENCIES (CONTINUED) New Hartford Property - continued The Company's estimate of its portion of the cost to assess the environmental conditions and remediate this site is $2.3 million, all of which has been accrued. The total amount paid to date in connection with these environmental remediation activities is $1.6 million. At June 29, 2018, the Company had $0.7 million accrued for these environmental remediation activities. A portion ($0.1 million) of the accrual related to this property is included in other current liabilities and the balance is included in other long-term liabilities. The remaining balance of the accrual reflects the total anticipated cost of completing these environmental remediation activities. Although it is reasonably possible that additional costs will be paid in connection with the resolution of this matter, the Company is unable to estimate the amount of such additional costs, if any, at this time. Bloomfield Property In connection with the Company’s 2008 purchase of the portion of the Bloomfield campus that Kaman Aerospace Corporation had leased from NAVAIR, the Company assumed responsibility for environmental remediation at the facility as may be required under the Transfer Act and is currently remediating the property under the guidance of the Connecticut Department of Environmental Protection ("CTDEP"). The assumed environmental liability of $10.3 million was determined by taking the undiscounted estimated remediation liability of $20.8 million and discounting it at a rate of 8%. This remediation process will take many years to complete. The total amount paid to date in connection with these environmental remediation activities is $13.5 million. At June 29, 2018, the Company had $2.2 million accrued for these environmental remediation activities. A portion ($0.4 million) of the accrual related to this property is included in other current liabilities, and the balance is included in other long-term liabilities. Although it is reasonably possible that additional costs will be paid in connection with the resolution of this matter, the Company is unable to estimate the amount of such additional costs, if any, at this time. Rimpar Property In connection with the Company's purchase of GRW, the Company assumed responsibility for the environmental remediation at the Rimpar, Germany facility. In 2016, the Company completed an assessment which determined the estimated remediation liability was $0.5 million. The total amount paid to date in connection with these environmental remediation activities is $0.2 million. The balance ($0.3 million) of the accrual related to this property is included in other current liabilities. Although it is reasonably possible that additional costs will be paid in connection with the resolution of this matter, the Company is unable to estimate the amount of such additional costs, if any, at this time. Aerospace Claim Matter On June 29, 2016, the Company received notification from a customer of their intent to file a claim for recovery of costs and expenses related to rework on certain aerostructure components previously delivered by the Company to the customer. The original notification did not indicate the extent of the rework undertaken by the customer, the cost or expenses incurred by the customer or the time frame in which the customer anticipated filing its formal claim. On October 17, 2017, the Company received a letter from the customer seeking to recover $12.4 million associated with the rework of these components and related costs incurred by the customer. The Company estimates the cost to rework the aerostructure components delivered to the customer over the time period in question is approximately $0.2 million. In the first half of 2018, the parties continued to exchange correspondence and supporting documentation to support their respective positions. The parties continue to seek resolution of this claim through further discussions and negotiations. The Company does not believe the claim has merit and will continue to vigorously defend against the claim, and will pursue appropriate legal remedies necessary to protect its position. Based on this analysis, the Company has accrued $0.2 million, the estimated cost to rework the aerostructure components, as of June 29, 2018; however, there can be no assurance that the ultimate resolution of this matter will not have a material adverse effect on the Company's results of operations, financial position and cash flows. 13. COMMITMENTS AND CONTINGENCIES (CONTINUED) Offset Agreement During January 2018, the Company entered into an offset agreement as a condition to obtaining orders from a foreign customer for the Company's JPF product. At June 29, 2018, the offset agreement had an outstanding notional value of approximately $194.0 million; however, the ultimate value is subject to the nature of the Company's satisfaction of these requirements. This agreement is designed to return economic value to the foreign country by requiring the Company to engage in activities supporting local defense or commercial industries, promoting a balance of trade, developing in-country technology capabilities or addressing other local development priorities. The offset agreement may be satisfied through activities that do not require a direct cash payment, including transferring technology, providing manufacturing, training and other consulting support to in-country projects and the purchase by third parties of supplies from in-country vendors. This agreement may also be satisfied through the Company's use of cash for activities, such as subcontracting with local partners, purchasing supplies from in-country vendors, providing financial support for in-country projects and making investments in local ventures. The amount ultimately applied against the offset agreement is based on negotiations with the customer and may require cash outlays that represent only a fraction of the notional value in the offset agreement. The offset program extends for several years and provides for potential penalties up to $16.5 million payable to the customer in the event the offset requirements of the contract are not met. The Company is currently in the process of developing a plan to satisfy the offset requirements.
