|(A) | The Company considered one-third of the rent expense as imputed interest factor.
|--- | --------------------------------------------------------------------------------

|(B) | Due to the registrants loss in 2014, 2013, 2012 and 2010, the ratio of earning to fixed charges was less than 1:1. The registrant must generate additional earnings of $469.2 million, $488.2 million, $612.4
million, and $790.3 million, respectively, to achieve a coverage ratio of 1:1.
