Net Income Per Common Unit

Computations of basic income per Common Unit are performed by dividing net income by the weighted average number of outstanding Common Units, and vested (and unissued) restricted units granted under the Partnership’s Restricted Unit Plan, as defined below, to retirement-eligible grantees.  Computations of diluted income per Common Unit are performed by dividing net income by the weighted average number of outstanding Common Units and unissued restricted units granted under the Restricted Unit Plan.  In computing diluted net income per Common Unit, weighted average units outstanding used to compute basic net income per Common Unit were increased by 329,409 and 296,878 units for the three and six months ended March 31, 2018, respectively, and 300,116 and 259,481 units for the three and six months ended March 25, 2017, respectively, to reflect the potential dilutive effect of the unvested restricted units outstanding using the treasury stock method.
