Financial Information

The Company’s financial information comparing its results during the quarter ended March 31, 2012 to the quarter ended March 31, 2011 can be read in its Quarterly Report on Form 10-Q, filed with the Securities and Exchange Commission on May 9, 2012.

First Quarter 2012 Significant Events

In mid-February 2012, we temporarily brought down the Mt. Vernon facility in order to perform needed maintenance.  Margins at Mt. Vernon have been under pressure due to strong corn basis in that region which could not be passed on to our customers.  When margins return, we will be prepared to bring this plant back on line and continue its progress to full rate.

On March 19, 2012, we entered into a separation agreement (the “Separation Agreement”) with Ben Borgen (“Mr. Borgen”), Senior Vice President, Commodity Risk Management, pursuant to which Mr. Borgen resigned from all positions held with us and our affiliates.  Under the terms of the Separation Agreement, Mr. Borgen received, among other things, (i) a termination payment of $700,000, which was paid to Mr. Borgen within thirty (30) days following his departure and (ii) 22,596 shares of our common stock, which were delivered to Mr. Borgen within thirty (30) days following his departure.  In addition, Mr. Borgen will receive 26,666 shares of our common stock in respect of his previously-vested restricted stock units, which will be settled six (6) months following his departure.  Mr. Borgen has previously vested in 42,750 stock options, which remained exercisable for thirty (30) days following his departure.  Mr. Borgen’s unvested stock options and all hybrid equity units, whether vested or unvested, have terminated.

EBITDA

We have included EBITDA and Adjusted EBITDA primarily as performance measures because management uses them as key measures of our performance. EBITDA is defined as earnings (which include gains or losses on derivative transactions) before interest expense, interest income, income tax expense, depreciation and amortization. EBITDA is not a measure of financial performance under accounting principles generally accepted in the U.S. (“GAAP”) and should not be considered an alternative to net earnings or any other measure of performance under GAAP. EBITDA has its limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. For example, EBITDA includes non-recurring loss items which are reflected in the statement of operations.

In order to emphasize the effects of certain income and loss items in our financial statements, we also report a second computation referred to as Adjusted EBITDA, which adjusts EBITDA for certain items. Adjusted EBITDA for the Company is adjusted for (i) separation payments to former senior staff, (ii) stock-based compensation expense, (iii) loss on early retirement of debt and (iv) loss on available for sale securities. Previously presented calculations have been modified to reflect the current definition of Adjusted EBITDA.

Management believes EBITDA and Adjusted EBITDA are meaningful supplemental measures of operating performance and highlight trends in our core business that may not otherwise be apparent when relying solely on GAAP financial measures.  We also believe that securities analysts, investors, and other

interested parties frequently use EBITDA in the evaluation of companies, many of which present EBITDA when reporting their results.  Additionally, management provides an Adjusted EBITDA measure so that investors will have the same financial information that management uses with the belief that it will assist investors in properly assessing the Company’s performance on a year-over-year and quarter-over-quarter basis.  Our management and external users of our financial statements, such as investors, commercial banks, research analysts, and others, use EBITDA and Adjusted EBITDA to assess:

·            the financial performance of our assets without regard to financing methods, capital structure or historical cost basis;

·            our operating performance and return on capital as compared to those of other companies in our industry, without regard to financing or capital structure; and

·            the feasibility of acquisitions and capital expenditure projects and the overall rate on alternative investment opportunities.

Reconciliation of Income (Loss) to EBITDA and Adjusted EBITDA

(a)     Interest capitalized during construction was $0.6 million for the three months ended March 31, 2012 and $1.9 million for the three months ended March 31, 2011.
