We continually monitor our aircraft fleet utilization in light of current and projected volume levels, aircraft fuel prices and other factors. Additionally, we monitor our other property, plant and equipment categories for any indicators that the carrying value of the assets exceeds the fair value. There were no indicators of impairment in our property, plant and equipment, and no impairment charges were recorded, during the three months ended March 31, 2014 and 2013.
