The Company uses OIBDAN, among other things, to evaluate the Company's operating performance. This measure is among the primary measures used by management for the planning and forecasting of future periods, as well as for measuring performance for compensation of executives and other members of management. We believe this measure is an important indicator of the Company's operational strength and performance of its business because it provides a link between profitability and net income. It is also a primary measure used by management in evaluating companies as potential acquisition targets.The Company believes the presentation of this measure is relevant and useful for investors because it allows investors to view performance in a manner similar to the method used by the Company's management. The Company believes it helps improve investors’ ability to understand the Company's operating performance and makes it easier to compare the Company's results with other companies that have different capital structures, stock option structures or tax rates. In addition, the Company believes this measure is also among the primary measures used externally by the Company's investors, analysts and peers in its industry for purposes of valuation and comparing the operating performance of the Company to other companies in its industry. Since OIBDAN is not a measure calculated in accordance with GAAP, it should not be considered in isolation of, or as a substitute for, net income as an indicator of operating performance and may not be comparable to similarly titled measures employed by other companies. OIBDAN is not necessarily a measure of the Company's ability to fund its cash needs. As it excludes certain financial information compared with operating income and net income (loss), the most directly comparable GAAP financial measures, users of this financial information should consider the types of events and transactions which are excluded. In addition, because a significant portion of the Company’s advertising operations are conducted in foreign markets, principally the Euro area, the U.K. and China, management reviews the operating results from its foreign operations on a constant dollar basis. A constant dollar basis (in which a foreign currency adjustment is made to show the 2013 actual foreign revenues, expenses and OIBDAN at average 2012 foreign exchange rates) allows for comparison of operations independent of foreign exchange rate movements.
