Schedule of multiemployer plans	The following table lists our participation in our multiemployer plans which we deem significant. “Contributions” represent the amounts contributed to the plan during the fiscal years presented:             Contributions (in millions) Pension Fund: EIN/Pension Plan Number Pension Act Zone Status FIP/RP Status Surcharge   2016   2015   2014 Lumber Employees Local 786 Retirement Fund (1) 516067407 Green (September 1, 2015) N/A No   $ 0.4   $ 0.4   $ 0.4 Central States, Southeast and Southwest Areas Pension Fund (2) 366044243 Critical and Declining (January 1, 2016) RP No   0.6   0.7   0.6 Other           0.4   1.2   — Total           $ 1.4   $ 2.3   $ 1.0 (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.
