Equity Based Compensation Equity Based Compensation
We incurred approximately $0.1 million of unit-based compensation expense related to the Partnership during both the three months ended March 31, 2019 and 2018. These amounts are included in general and administrative expenses in the accompanying condensed consolidated statements of income and comprehensive income. The fair value of phantom unit awards under the Delek Logistics GP, LLC 2012 Long-Term Incentive Plan (the "LTIP") is determined based on the closing market 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. Awards vest over one- to five-year service periods, unless such awards are amended in accordance with the LTIP.
As of March 31, 2019, there was $0.1 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 0.2 years.
