Use of Non-GAAP Financial Measure
The Company provides a non−GAAP adjusted EBITDA disclosure as a supplemental measure to U.S. GAAP regarding our operational performance. This financial measure excludes the impact of certain items and, therefore, has not been calculated in accordance with U.S. GAAP. This press release also contains a reconciliation of the non−GAAP financial measure to its most comparable U.S. GAAP financial measure.

The Company believes that the additional non−GAAP financial measure is useful to investors in assessing the Company’s operating performance. Management also uses this measure internally to evaluate the Company's operating performance, and the measure is used for planning and forecasting of future periods. In addition, financial analysts that follow our Company may focus on and publish both historical results and future projections based on our non−GAAP financial measure. We also believe that it is in the best interest of our investors to provide this non-GAAP information.

While management believes that this non−GAAP financial measure provides useful supplemental information to investors, there are limitations associated with the use of this non−GAAP financial measure. Our non-GAAP financial measure may not be reported by all of the Company's competitors and it may not be directly comparable to similarly titled measures of other companies due to potential differences in calculation. The Company compensates for these limitations by using this non−GAAP financial measure as a supplement to U.S. GAAP and by providing a reconciliation of the non−GAAP financial measure to its most comparable U.S. GAAP financial measure.
Non−GAAP financial measures are not in accordance with or an alternative for U.S. GAAP. The Company's non−GAAP financial measure is not meant to be considered in isolation or as a substitute for comparable U.S. GAAP financial measures, and should be read only in conjunction with the Company's consolidated financial statements prepared in accordance with U.S. GAAP.
