All Stock Transaction Details Key Combination Metrics Preliminary pro-forma 12 months ended December 31, 2016 Preliminary pro-forma March 31, 2017 Net debt is calculated by subtracting cash and cash equivalents from total debt. Net debt to capitalization is calculated by dividing (a) net debt by the sum of (b) net debt and total equity. FMV adjusted net debt to capitalization is calculated by adjusting capitalization based on estimated fair market value of vessels. These are non-GAAP financial measures. Please refer to “Definitions and Non-GAAP Financial Measures” which contain definitions of these terms and reconciliations of these non-GAAP financial measures as used in this presentation to the most directly comparable financial measures under United States generally accepted accounting principles (GAAP).

This presentation includes financial measures that are non-GAAP financial measures as defined under the rules of the U.S. Securities and Exchange Commission. These non-GAAP financial measures include Net Debt, Net Debt to Capitalization and FMV Adjusted Net Debt to Capitalization for both Pre-Transaction and Post-Transaction and are intended to provide additional information and should not be considered a substitute for measures of performance prepared in accordance with GAAP. In addition, these measures do not have standardized meanings, and may not be comparable to similar measures presented by other companies. The Company believes that certain investors use this information to evaluate the Company’s financial leverage, as does management. The following table reconciles these measures to the most directly comparable financial measures under United States generally accepted accounting principles (GAAP). The $581.4 million adjustment represents the impact on the Company’s capitalization as if its vessels were recognized at their estimated fair market value instead of historical carrying value. Net debt is adjusted by including the $309.3 million of net debt of TIL as of March 31, 2017. Capitalization is further adjusted by adding $223.2 million, representing the total equity of TIL as of March 31, 2017 adjusted as if its vessels were recognized at their estimated fair market value instead of historical carrying value.
