For the three and six months ended June 30, 2013 and 2012, we had weighted average preferred units outstanding of 16,666,667. For the three months ended June 30, 2013 and 2012, we had 6,133,558 and zero Class B units outstanding, respectively. For the six months ended June 30, 2013 and 2012, we had 4,961,597 and zero Class B units outstanding, 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 been included in the diluted earnings per unit calculation for the three months ended June 30, 2013 as they were dilutive for the period, but have not been included in the diluted earnings per unit calculation for the six months ended June 30, 2013, as they were anti-dilutive for the period. The preferred units were included in the diluted earnings per unit calculation for the three and six months ended June 30, 2012 as they were dilutive for the periods.
