| (1) | Represents the estimated portion of rental expense from operating leases that is considered by us to be representative of interest. |
| (2) | We have not had any preferred stock outstanding during the periods presented; therefore, the ratio of earnings to (and the deficiency of earnings available to cover) combined fixed charges and preferred stock dividends is the same as our ratio of earnings to (and the deficiency of earnings available to cover) fixed charges alone. |
| (3) | Earnings were insufficient to cover fixed charges for each of the periods presented. The amount of the coverage deficiency was $28.1 million, $90.1 million, $77.7 million, $37.5 million and $67.3 million for the years ended December 31, 2011, 2012, 2013, 2014 and 2015, respectively. |
