The Company capitalizes interest expense as part of the cost of construction of facilities and equipment. Interest expense capitalized in 2014, 2013 and 2012 was $115 million, $105 million and $115 million, respectively.
Depreciation expense, including the amortization of capitalized interest in 2014, 2013 and 2012, was $2.5 billion, $2.7 billion and $2.5 billion, respectively.
Upon retirement or other disposal of property, plant and equipment, the costs and related amounts of accumulated depreciation or amortization are eliminated from the asset and accumulated depreciation accounts, respectively. The difference, if any, between the net asset value and the proceeds are recorded in earnings.
