(a) Unless otherwise noted in the table, the most recent Pension Protection Act zone status available in 2015 and 2014 is for the plan’s year-end at December 31, 2014 and 2013, respectively. The zone status is based on information that we received from the plan and is certified by the plan’s actuary. As defined in the Pension Protection Act of 2006, among other factors, plans reported as critical are generally less than 65% funded and plans reported as endangered are generally less than 80% funded.

(b) The “FIP/RP Status” column indicates plans for which a Funding Improvement Plan (“FIP”) or a Rehabilitation Plan (“RP”) is either pending or has been implemented.

(c) A multiemployer defined benefit pension plan that has been certified as endangered, seriously endangered or critical may begin to levy a statutory surcharge on contribution rates. Once authorized, the surcharge is at the rate of 5% for the first 12 months and 10% for any periods thereafter. Contributing employers, however, may eliminate the surcharge by entering into a collective bargaining agreement that meets the requirements of the applicable FIP or RP.

(d) The Company was listed in the Form 5500 of the multiemployer plans considered to be individually significant as providing more than 5% of the total contributions for each of the following plans and plan years:

	Year Contributions to Plan Exceeded 5% of Total Contributions (as of Plan’s Year End)
