2013 Goodwill Impairment In 2013, the estimated fair value of the Statia Terminals reporting unit was less than its carrying value. To determine the amount of goodwill impairment loss, we first considered whether any other assets assigned to the Statia Terminals reporting unit were impaired. The only significant assets of this reporting unit, other than goodwill, consist of property, plant and equipment, which we determined were fully recoverable. The hypothetical fair value allocation for the Statia Terminals reporting unit indicated the estimated fair value of goodwill was $0. As a result, we recognized a $304.5 million goodwill impairment charge in the fourth quarter of 2013, which represented all of the goodwill allocated to the Statia Terminals reporting unit. The goodwill impairment charge resulted from changes in demand for storage at our St. Eustatius and Point Tupper terminal locations. Increased supply from various shale formations within the U.S. has reduced the need for storage at these locations, which historically functioned as break bulk facilities for light crude moving from foreign sources into the U.S. These changes in crude flow patterns, as well as the backwardation of the forward pricing curve, reduced demand at these terminals. Primarily resulting from those factors, a customer at our St. Eustatius terminal vacated a significant portion of its storage in the fourth quarter of 2013.
