In accordance with its policy, the Company reviews the estimated useful lives of its fixed assets on an ongoing basis. This review indicated that the actual lives of certain co-location assets were longer than the estimated useful lives used for depreciation purposes in the Company's financial statements. As a result, effective August 1, 2016, the Company changed its estimates of the useful lives of its co-location assets to better reflect the estimated periods during which these assets will remain in service. The estimated useful lives of the co-location assets that previously averaged three years were increased to an average of four years. The effect of this change in estimate was to reduce depreciation expense and net loss for the twelve months ended December 31, 2016 by $1.0 million and decrease basic and diluted loss per share by $0.02. Aggregate depreciation expense for property and equipment was $12.0 million, $12.1 million and $9.1 million for the years ended December 31, 2016, 2015 and 2014, respectively.
