(1)	The zone status represents the most recent available information for the respective MEPP, which may be 2012 or earlier for the 2013 year and 2011 or earlier for the 2012 year.

(2)

This information was obtained from the respective plans' Form 5500 for the most current available filing. These dates may not correspond with our fiscal year contributions. The above noted percentages of contributions are based upon disclosures contained in the plans' Form 5500 filing (“Forms”). Those Forms, among other things, disclose the names of individual participating employers whose annual contributions account for more than 5% of the aggregate annual amount contributed by all participating employers for a plan year. Accordingly, if the annual contribution of two or more of our subsidiaries each accounted for less than 5% of such contributions, but in the aggregate accounted for in excess of 5% of such contributions, that greater percentage is not available and accordingly is not disclosed.


(3)	For these respective plans, a funding surcharge was currently in effect for 2013.
