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

|(B) | Due to the registrants loss in 2013, 2012, 2010 and 2009, the ratio of earning to fixed charges was less than 1:1. The registrant must generate additional earnings of $488.2 million, $612.4 million, $790.3
million, and $1,136.9 million, respectively to achieve a coverage ratio of 1:1.
