The Partnership's performance-based phantom unit awards include tandem distribution equivalent rights ("DERs") which entitle the participant to a cash payment upon vesting that is equal to any cash distribution paid on a common unit between the grant date and the date the phantom units were settled. Payments made in connection with DERs are recorded as a distribution in unitholders' equity and totaled $0.3 million during the year ended December 31, 2016.

In addition, on January 27, 2017 the Partnership declared a cash distribution for the three months ended December 31, 2016, of $0.5775 per unit, totaling $13.0 million (including a $0.6 million IDR distribution). Such distributions were paid on February 14, 2017, to unitholders of record on February 8, 2017.
