On December 30, 2014, the Company entered into a definitive merger agreement with Aventine, a Midwest ethanol producer, under which the Company agreed to acquire Aventine through a stock-for-stock merger. The merger agreement was amended effective March 31, 2015 to address certain conditions to closing and other matters. The acquisition closed on July 1, 2015 and the Company issued an aggregate of 17.8 million shares of common stock and non-voting common stock for 100% of the outstanding shares of common stock of Aventine. The common stock and non-voting common stock issued as consideration had an aggregate fair value of $174.6 million, based on the closing market price of the Company’s common stock on the acquisition date.

The Company believes the Aventine acquisition will result in a number of synergies and strategic advantages. The Company believes the acquisition will spread commodity and basis price risks across diverse markets and products, assisting in its efforts to optimize margin management; improve its hedging opportunities with a greater correlation to the liquid physical and paper markets in Chicago; and increase its flexibility and alternatives in feedstock procurement for its Midwestern and Western production facilities. The acquisition also expands the Company’s marketing reach into new markets and extends its mix of co-products. The Company believes the acquisition will enable it to have deeper market insight and engagement in major ethanol and feed markets outside the Western United States, thereby improving pricing opportunities; allows the Company to establish access to markets in 48 states for ethanol sales and access many markets with ethanol and co-product sales reaching domestic and international customers; and enable it to use its more diverse mix of co-products to generate strong co-product returns. In addition, the acquisition also increases the Company’s combined annual ethanol production capacity to 515 million gallons per year and annualized ethanol marketing volume to over 800 million gallons, including Aventine’s historical volumes.

The Company has recognized the following allocation of the purchase price at fair values. The following fair value allocation for all assets and liabilities is provisional and incomplete as the Company is in the process of completing its valuation of the assets acquired and liabilities assumed, most significantly its valuation of property and equipment, deferred taxes and environmental remediation. The fair values of property and equipment and deferred taxes are based on the Company’s draft valuations, and represent its best estimates at the time of the filing of this report. The Company expects to conclude its valuations during the fourth quarter of 2015. The Company has included in the following allocation its estimated fair values for certain operating lease agreements and open commitments. The fair-value determination of long-term debt is based on the interest rate environment at the acquisition date.

Based upon these fair value estimates, the purchase price consideration allocation is as follows (in thousands):

The contractual amount due on the accounts receivable acquired was $10.8 million, of which $0.4 million is expected to be uncollectible. Any changes to the initial estimates of the fair value of the acquired assets and assumed liabilities will be recorded as adjustments to those assets and liabilities and residual amounts will be allocated to goodwill if the net assets acquired are less than the purchase price. If the net assets acquired exceed the purchase price, the residual amount will result in a bargain purchase gain. As discussed in Note 9, the Company recognized $3.7 million, included in other noncurrent liabilities above, as a litigation contingency related to certain legal cases for amounts that were probable and estimable as of the acquisition date. Subsequent to the acquisition date, the Company paid approximately $0.4 million of this amount.

The following table presents unaudited pro forma financial information assuming the acquisition occurred on January 1, 2014 (in thousands, except per share).

The effects of the initial step-up of inventories and open contracts in the aggregate of $8.7 million recorded during the three months ended September 30, 2015 were excluded in the above amounts, and instead recorded for the nine months ended September 30, 2014, as if the acquisition had occurred on January 1, 2014. For the three months ended September 30, 2015, Aventine contributed $143.6 million in net revenues and $16.6 million in pre-tax loss. For the three and nine months ended September 30, 2015, the Company recorded approximately $0.1 million and $1.4 million, respectively, in costs associated with the Aventine acquisition. These costs are reflected in selling, general and administrative expenses on the Company’s consolidated statements of operations, but were excluded from the amounts above.
