[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. Therefore, as a result of the public offering of common units in January 2013, and the conversion of the subordinated units to common units in May 2014, net income per common and subordinated limited partner units may not agree for the periods presented

[2] On May 16, 2014, the 15,254,890 subordinated units were converted into common units on a one-for-one basis and thereafter participate on terms equal with all other common units in distributions of available cash. Distributions and the Partnership’s net income were allocated to the subordinated units through May 15, 2014.
