Although they reflect INSW’s current expectations, these statements are not guarantees of future performance, but involve a number of risks, uncertainties, and assumptions which are difficult to predict. Some of the factor s t hat may cause actual outcomes and results to differ materially from those expressed in, or implied by, the forward - looking statements include, but are not necessarily limited to, vessel acquisitions, general economic conditions, competitive pressures, the nature of the Company’s ser vices and their price movements, and the ability to retain key employees.

Non - GAAP Financial Measures Included in this presentation are certain non - GAAP financial measures, including Time Charter Equivalent (“TCE”) revenue, EBITDA , Adjusted EBITDA, and total leverage ratios, designed to complement the financial information presented in accordance with generally ac cep ted accounting principles in the United States of America because management believes such measures are useful to investors. TCE revenues, w hic h represents shipping revenues less voyage expenses, is a measure to compare revenue generated from a voyage charter to revenue generated fro m a time charter. EBITDA represents net (loss)/income before interest expense, income taxes and depreciation and amortization expense. Ad justed EBITDA consists of EBITDA adjusted for the impact of certain items that we do not consider indicative of our ongoing operating perfo rma nce. Total leverage ratios are calculated as total debt divided by Adjusted EBITDA. We present non - GAAP measures when we believe that the a dditional information is useful and meaningful to investors. Non - GAAP financial measures do not have any standardized meaning and are ther efore unlikely to be comparable to similar measures presented by other companies. The presentation of non - GAAP financial measures is not intend ed to be a substitute for, and should not be considered in isolation from, the financial measures reported in accordance with GAAP. See App endix for a reconciliation of certain non - GAAP measures to the comparable GAAP measures.
