Our multiemployer pension plan withdrawal liability was approximately $116 million as of December 28, 2014 and $119 million as of December 29, 2013. This liability represents the present value of the obligations related to complete and partial withdrawals that have already occurred, as well as an estimate of future partial withdrawals that we considered probable and reasonably estimable. For those plans that have yet to provide us with a demand letter, the actual liability will not be fully known until they complete a final assessment of the withdrawal liability and issue a demand to us. Therefore, the estimate of our multiemployer pension plan liability will be adjusted as more information becomes available that allows us to refine our estimates.
