__________________

(1) | For purposes of computing this ratio, we have excluded interest income from interest expense amounts reported on the consolidated statement of operations.

(2) | The ratio has been computed by dividing earnings (loss) by fixed charges. For purposes of computing the ratio, the numerator consists of the sum of (i) earnings (loss), which includes income before income taxes, and (ii) fixed charges. The denominator consists of fixed charges, which includes interest expense and a portion of rentals representative of an implicit interest factor for such rentals.

(3) | Due to our net losses for the years ended December 31, 2015, 2016 and 2017, the coverage ratio for each of these periods was less than 1:1. To achieve a coverage ratio of 1:1, we would have needed additional earnings of approximately $242.4 million, $49.4 million and $91.3 million for the years ended December 31, 2015, 2016 and 2017, respectively.
