Though management finds adjusted-EBITDA useful for evaluating aspects of the Company's business, its reliance on this measure is limited because excluded items often have a material effect on the Company's earnings and earnings per common share calculated in accordance with GAAP. Therefore, management uses adjusted-EBITDA in conjunction with GAAP earnings and earnings per common share measures. The Company believes that adjusted-EBITDA provides investors with an additional tool for evaluating the Company's core performance, which management uses in its own evaluation of overall performance, and a baseline for assessing the future earnings potential of the Company. While the GAAP results are more complete, the Company prefers to allow investors to have this supplemental metric since, with a reconciliation to GAAP, it may provide greater insight into the Company's financial results.
