Depreciation expense for 2015, 2014 and 2013 was $105.8, $106.5 and $105.3, respectively. Amortization expense on computer software and leasehold improvements for 2015, 2014 and 2013 was $409.8, $367.8 and $351.8, respectively, which includes amortization expense on computer software, both purchased and internally developed, for 2015, 2014 and 2013 of $366.7, $329.2 and $313.6, respectively. Capitalized costs related to the internal development of software of $2,024.7 and $1,844.2 at December 31, 2015 and 2014, respectively, are reported with computer software. 

During the years ended December 31, 2015, 2014 and 2013, we recognized $1.8, $7.9 and $47.7, respectively, of impairments related to computer software (primarily internally developed) due to project cancellation or asset replacement, some of which resulted from a change in strategic focus needed to effectively manage business operations in a post-Health Care Reform environment.
