Equity Based Compensation [Abstract] |
Equity Based Compensation | Equity Based Compensation We incurred $0.1 million and $0.2 million of unit-based compensation expense related to the Partnership during the three and six months ended June 30, 2015, respectively, and a nominal amount and $0.1 million during the three and six months ended June 30, 2014, respectively. These amounts are included in general and administrative expenses in the accompanying condensed consolidated statements of income. The fair value of phantom unit awards under the LTIP is determined based on the closing price of our common limited partner units on the grant date. The estimated fair value of our phantom units is amortized over the vesting period using the straight line method. All awards made through June 9, 2015 vest over a five-year service period unless such awards are amended in accordance with the LTIP. Beginning June 10, 2015, all awards made to only non-employee directors vest over a three-year service period unless such awards are amended in accordance with the LTIP. As of June 30, 2015, there was $1.1 million of total unrecognized compensation cost related to non-vested equity-based compensation arrangements, which is expected to be recognized over a weighted-average period of 2.4 years.
