(1)
The Company’s contribution represents more than 5% of the total contributions to the plan.
(2)
The Pension Fund’s board adopted a Funding Improvement Plan on October 21, 2015, continuing the existing plan which increased the weekly pension fund contribution rates by $75 with corresponding decreases to the weekly welfare fund contribution rates until December 31, 2017.
(3)
Critical status triggered a 5% surcharge on employer contributions effective June 2012.  Effective January 1, 2013, this surcharge increases to 10%. The surcharge ended on October 21, 2015 when the rehabilitation plan commenced.

(a)
The “EIN / PN” column provides the Employer Identification Number and the three-digit plan number assigned to a plan by the Internal Revenue Service.
(b)
The most recent Pension Protection Act Zone Status available for 2014 and 2013 is for plan years that ended in 2014 and 2013, respectively. The zone status is based on information provided to the Company and other participating employers by each plan and is certified by the plan’s actuary. A plan in the “red” zone has been determined to be in “critical status”, based on criteria established under the Internal Revenue Code (“Code”), and is generally less than 65% funded. A plan in the “yellow” zone has been determined to be in “endangered status”, based on criteria established under the Code, and is generally less than 80% funded. A plan in the “green” zone has been determined to be neither in “critical status” nor in “endangered status”, and is generally at least 80% funded.
(c)
The “FIP/RP Status Pending/Implemented” column indicates whether a Funding Improvement Plan, as required under the Code to be adopted by plans in the “yellow” zone, or a Rehabilitation Plan, as required under the Code to be adopted by plans in the “red” zone, is pending or has been implemented as of the end of the plan year that ended in 2016.
(d)
The “Surcharge Imposed” column indicates whether the Company’s contribution rate for 2016 included an amount in addition the contribution rate specified in the applicable collective bargaining agreement, as imposed by a plan in “critical status”, in accordance with the requirements of the Code.
