Phantom units are considered participating securities for purposes of computing basic earnings per unit. See Note 13 for information regarding the phantom units.
(2)
We use the “if-converted method” to determine the potential dilutive effect of the vesting of phantom unit awards and the conversion of preferred units outstanding.  See Note 13 for information regarding phantom unit awards.  See Note 8 for information regarding preferred units.
