Earnings were insufficient to cover combined fixed charges by $27,093 in 2015, $20,176 in 2014, $13,112 in 2013 and $18,365 in 2012.
(1) Represents the estimated portion of operating lease rental expense that is considered by us to be representative of interest.
For the periods indicated above, we had no outstanding shares of preferred stock with required dividend payments. Therefore, the ratios of earnings to combined fixed charges and preferred stock dividends are identical to the ratios presented in the tables above.
