(1) Consistent with market practice, management has estimated that interest within rental expense is equal to 33% of lease expense, calculated as follows:

	2013		2014		2015		2016		2017
Lease Expense		54,753		56,871		56,210		55,170		60,864
Interest (33%)		18,068		18,767		18,549		18,206		20,085

(2) The ratios of earnings to fixed charges were computed by dividing earnings by fixed charges.
