EBITDA is calculated as net income before interest expense, provision for income taxes and depreciation and amortization. Adjusted EBITDA further adjusts EBITDA to reflect the additions and eliminations described in the table below.

EBITDA and adjusted EBITDA are presented because: (i) we believe they are useful measures for investors to assess the operating performance of our business without the effect of non-cash charges such as depreciation and amortization expenses and asset disposals, closure costs and restaurant impairments and (ii) we use adjusted EBITDA internally as a benchmark for certain of our cash incentive plans and to evaluate our operating performance or compare our performance to that of our competitors. The use of adjusted EBITDA as a performance measure permits a comparative assessment of our operating performance relative to our performance based on our US GAAP results, while isolating the effects of some items that vary from period to period without any correlation to core operating performance or that vary widely among similar companies. Companies within our industry exhibit significant variations with respect to capital structures and cost of capital (which affect interest expense and income tax rates) and differences in book depreciation of property, plant and equipment (which affect relative depreciation expense), including significant differences in the depreciable lives of similar assets among various companies. Our management believes that adjusted EBITDA facilitates company-to-company comparisons within our industry by eliminating some of these foregoing variations. Adjusted EBITDA as presented may not be comparable to other similarly-titled measures of other companies, and our presentation of adjusted EBITDA should not be construed as an inference that our future results will be unaffected by excluded or unusual items.

(a) The third quarter of 2012 and the first three quarters of 2013 and 2012 included $250,000, $500,000 and $750,000, respectively, of management fee expense in accordance with our management services agreement and through the Class C common stock dividend paid to the holder of the one outstanding share of our Class C common stock. In connection with our IPO, the management services agreement expired and the one share of Class C common stock was redeemed.
