[2] For the three and nine months ended September 30, 2013 and 2012, we had weighted average preferred units outstanding of 16,666,667. For the three months ended September 30, 2013 and 2012, we had weighted average Class B units outstanding of 6,133,558 and zero. For the nine months ended September 30, 2013 and 2012, we had weighted average of Class B units outstanding of 5,987,364 and zero, respectively. The preferred and Class B units are contingently convertible into common units and could potentially dilute earnings per unit in the future. The preferred and Class B units have not been included in the diluted earnings per unit calculation for the three and nine months ended September 30, 2013, as they were anti-dilutive for the periods. The preferred units were not included in the diluted earnings per unit calculation for the three and nine months ended September 30, 2012, as they were anti-dilutive for the periods.
