| | (2) | On December 21, 2015, the federal government enacted legislation that reinstated an excise tax credit program available for certain biofuel blending activities. This program had previously expired on December 31, 2014 and was reinstated retroactively to January 1, 2015. During the three months ended December 31, 2015, the Partnership recorded federal excise tax credits of $7.8 million related to its biofuel blending activities that had occurred throughout the year. These credits have been recorded as a reduction of cost of products sold (exclusive of depreciation and amortization) for the three months ended December 31, 2015. |
