(1) Our contributions for fiscal 2016 and 2015 exceeded 5% of total plan contributions, and we were deemed to be a significant contributor to this plan. The plan fiscal year began on September 1, 2016, and to date, we have likely contributed over 5% of the total plan’s contributions. The collective bargaining agreement requiring contributions to this plan expired on September 30, 2016, and we are currently negotiating a new agreement with the union. (2) We did not contribute more than 5% of total plan contributions to this plan; however, this plan is deemed significant as it is severely underfunded, and we may, in the future, record a liability if required by an event of our withdrawal from the plan or a mass withdrawal. Our contingent fiscal 2016 withdrawal liability was estimated at approximately $30.7 million.
