Non-GAAP Financial Measures
In this press release, FutureFuel used adjusted EBITDA as a key operating metric to measure both performance and liquidity. Adjusted EBITDA is a non-GAAP financial measure. Adjusted EBITDA is not a substitute for operating income, net income, or cash flow from operating activities (each as determined in accordance with GAAP), as a measure of performance or liquidity. Adjusted EBITDA has limitations as an analytical tool, and should not be considered in isolation or as a substitute for analysis of results as reported under GAAP. FutureFuel defines adjusted EBITDA as net income before interest, income taxes, depreciation, and amortization expenses, excluding, when applicable, non-cash share-based compensation expense, public offering expenses, acquisition-related transaction costs, purchase accounting adjustments, loss on disposal of property and equipment, gains or losses on derivative instruments, other non-operating income or expense, and, in 2013, the impact from the retroactive reinstatement of the 2012 $1.00 biodiesel blenders tax credit. Information relating to adjusted EBITDA is provided so that investors have the same data that management employs in assessing the overall operation and liquidity of FutureFuel's business. FutureFuel's calculation of adjusted EBITDA may be different from similarly titled measures used by other companies; therefore, the results of its calculation are not necessarily comparable to the results of other companies.
Adjusted EBITDA allows FutureFuel's chief operating decision makers to assess the performance and liquidity of FutureFuel's business on a consolidated basis to assess the ability of its operating segments to produce operating cash flow to fund working capital needs, to fund capital expenditures, and to pay dividends. In particular, FutureFuel management believes that adjusted EBITDA permits a comparative assessment of FutureFuel's operating performance and liquidity, relative to a performance and liquidity based on GAAP results, while isolating the effects of depreciation and amortization, which may vary among its operating segments without any correlation to their underlying operating performance, and of non-cash stock-based compensation expense, which is a non-cash expense that varies widely among similar companies, and gains and losses on derivative instruments, whose immediate recognition can cause net income to be volatile from quarter to quarter due to the timing of the valuation change in the derivative instruments relative to the sale of biofuel.
