Commitments and Contingencies During the fourth quarter of fiscal 2016, one of the Companys subsidiaries ceased operations. This subsidiary contributed to a multiemployer pension plan, the Pension, Hospitalization and Benefit Plan of the Electrical Industry - Pension Trust Fund (the Plan). In October 2016, the Plan demanded payment for a claimed withdrawal liability of approximately $13.0 million .
