[2] For the three and nine months ended September 30, 2014 and 2013, we had weighted average preferred units outstanding of 16,666,667. The preferred and Class B units are contingently convertible into common units and could potentially dilute earnings per unit in the future. Upon issuance, 11.6 million of deferred Class B units would also be convertible into common units and could potentially dilute earnings per unit in the future. For the three months ended September 30, 2014, the preferred, the deferred Class B, and the Class B units have been included in the diluted earnings per unit calculation as they were dilutive for the period, however were not included in the nine months ended September 30, 2014 diluted earnings per unit calculation as they were anti-dilutive for the period. 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 period.
