NET INCOME PER UNIT

We treat restricted units granted under our long-term incentive plan as participating securities in computing net income per unit pursuant to the two-class method. The computation of diluted net income per unit for the three and nine months ended September 30, 2013 excludes 289,100 outstanding options to purchase NuStar GP Holdings units, as the exercise price exceeded the average market price and their effect would have been anti-dilutive. Unit amounts used in the computation of basic and diluted net income per unit were as follows:
