We are a party to various litigation and legal proceedings which we believe, based on advice of counsel, will not either individually or in the aggregate have a material adverse effect on our financial condition, results of operations or cash flows.

Pursuant to the 2007 Energy Independence and Security Act, the Environmental Protection Agency (“EPA”) promulgated the Renewable Fuel Standard 2 (“RFS2”) regulations reflecting the increased volume of renewable fuels mandated to be blended into the nation's fuel supply. The regulations, in part, require refiners to add annually increasing amounts of “renewable fuels” to their petroleum products or purchase credits, known as renewable identification numbers (“RINs”), in lieu of such blending. The EPA has not yet finalized the 2014 nor the 2015 percentage standards under its RFS2 program. The estimated quantity of renewable fuels or RINs that we are required to purchase and that have been accrued for as of March 31, 2015 and December 31, 2014, as well as for the three months and year then ended, are based on quantities proposed by the EPA in November 2013.
