13. Equity-Based Compensation

Our General Partner's board of directors adopted the LTIP for the benefit of employees, consultants and non-employee directors of our General Partner and its affiliates. Awards granted under the LTIP vest over a scheduled vesting period and their market value at the date of the grant is amortized over the restricted period on a straight-line basis.

At September 30, 2015, there were 4,165,952 common units reserved for future grants under the LTIP.

The fair value of the phantom units is determined based on the closing price of WNRL common units on the grant date. The estimated fair value of the phantom units is amortized on a straight-line basis over the scheduled vesting periods of individual awards. We incurred unit-based compensation expense of $0.6 million, $1.5 million, $0.5 million and $1.1 million for the three and nine months ended September 30, 2015 and 2014, respectively.

The aggregate grant date fair value of nonvested phantom units outstanding as of September 30, 2015, was $7.9 million. The aggregate intrinsic value of such phantom units was $5.8 million. Total unrecognized compensation cost related to our nonvested phantom units totaled $6.8 million at September 30, 2015, that we expect to recognize over a weighted-average period of 3.59 years.

A summary of our unit award activity for the nine months ended September 30, 2015, is set forth below:
