(a) Includes amortization of deferred financing costs in all periods and bridge financing fees in 2015. The Company’s policy is to classify interest expense recognized on uncertain tax positions as income tax expense. The Company has excluded interest expense recognized on uncertain tax positions from the Ratio of Earnings to Fixed Charges. Capitalized interest is not considered material.

(b) Interest portion of rental expense is estimated to equal 1/3 of such expense, which is considered a reasonable approximation of the interest factor.

(c) Earnings were not sufficient to cover fixed charges for the period, which included goodwill and long-lived asset impairment charges of $401,667. The earnings shortfall was $366,505.
