________________ | | (1) | During the year ended December 31, 2014, we sold our Willbridge, Oregon asphalt terminal, which was allocated goodwill of $4,030 at the time of disposition. |
| | (2) | The volatility in the crude price environment during 2015 caused a reduction in the growth rate for U.S. crude oil production, which subsequently caused a reduction in U.S. crude oil price discounts compared to waterborne crude prices. As a result, we have delayed planned projects within the California refining reporting unit, which had a negative effect on the timing of future cash flows. We recognized a goodwill impairment loss of $39,028 related to our California refining reporting unit for the year ended December 31, 2015. |
