EBITDA Reconciliation

Source: Unaudited, Company financials

We are adding depreciation and amortization to operating income to calculate EBITDA. It is a key financial measure used by our senior management to internally evaluate the performance of our business and for other required or discretionary purposes.

We believe that the presentation of EBITDA will enhance an investor’s understanding of our operating performance as we believe it is commonly reported and widely used by analysts and investors in our industry. It also provides useful information for comparison on a more comparable basis of our operating performance and those of our competitors, who follow different accounting policies.

EBITDA is not a measure determined in accordance with GAAP. Our calculation of EBITDA may not be comparable to similarly titled measures reported by other companies.
