[1] We base our calculation of net income per unit on the weighted-average number of common and subordinated limited partner units outstanding during the period. The weighted-average number of common and subordinated units reflect the conversion of the subordinated units to common units on February 25, 2016. See Notes 5 and 12 for further discussion.

[2] General partner distributions (including IDRs) consist of the 2% general partner interest and IDRs, which represent the right of the general partner to receive increasing percentages of quarterly distributions of available cash from operating surplus in excess of $0.43125 per unit per quarter. See Note 12 for further discussion related to IDRs.

[3] We base our calculation of net income per unit on the weighted-average number of common and subordinated limited partner units outstanding during the period. The weighted-average number of common and subordinated units reflects the conversion of the subordinated units to common units on February 25, 2016.

[4] There were no outstanding common unit equivalents excluded from the diluted earnings per unit calculation during the year ended December 31, 2017. Outstanding common unit equivalents totaling 4,240 and 6,200 were excluded from the diluted earnings per unit calculation for the years ended December 31, 2016 and 2015, respectively, as these common unit equivalents did not have a dilutive effect under the treasury stock method.

[5] On February 25, 2016, all of the Partnership's 11,999,258 outstanding subordinated units converted into common units and began participating pro rata with the other common units in distributions of available cash. Distributions and the Partnership's net income were allocated to the subordinated units through February 24, 2016.
