Adjusted net income and adjusted earnings per diluted share represent net income and earnings per diluted share, respectively, as determined under GAAP, excluding a loss recognized on impairment of assets held for sale. The Company believes that the presentation of adjusted net income and adjusted earnings per diluted share for the three and six months ended June 30, 2013 and June 30, 2012 allows investors to make meaningful comparisons of the Company's operating performance between periods and to view its business from the same perspective as its management. Because the excluded item is not predictable or consistent, management does not consider it when evaluating the Company's performance or when making decisions regarding allocation of resources.
Adjusted EBITDA represents net income before interest, taxes, depreciation and amortization, as further adjusted for certain charges related to certain unrelated legal fees and consulting fees, impairment on assets held for sale and stock based compensation. The Company uses, and believes its investors benefit from the presentation of, Adjusted EBITDA in evaluating the Company's operating performance because adjusted EBITDA provides the Company and its investors with additional tools to compare its operating performance on a consistent basis by removing the impact of certain items that management believes do not directly reflect the Company's core operations. In addition, the Company believes that Adjusted EBITDA is useful to investors and other external users of its consolidated financial statements in evaluating the Company's operating performance as compared to that of other companies, because it allows them to measure a company's operating performance without regard to items such as interest expense, taxes, depreciation and amortization, which can vary substantially from company to company depending upon accounting methods and book value of assets and liabilities, capital structure and the method by which assets were acquired. The Company's management also uses adjusted EBITDA for planning purposes, including the preparation of its annual operating budget and financial projections, and to evaluate the Company's ability to make certain payments, including dividends, in compliance with its senior credit facilities, which is determined based on a calculation of "Consolidated Adjusted EBITDA" that is substantially similar to adjusted EBITDA.
