operating activities cash provided by operating activities decreased in 2015 compared to 2014 due to lower net income and changes in working capital , partially offset by the timing of tax payments . federal tax law provided for 100% ( 100 % ) bonus depreciation for qualified investments made during 2011 and 50% ( 50 % ) bonus depreciation for qualified investments made during 2012-2013 . as a result , the company deferred a substantial portion of its 2011-2013 income tax expense , contributing to the positive operating cash flow in those years . congress extended 50% ( 50 % ) bonus depreciation for 2014 , but this extension occurred in december , and the related benefit was realized in 2015 , rather than 2014 . similarly , in december of 2015 , congress extended bonus depreciation through 2019 , which delayed the benefit of 2015 bonus depreciation into 2016 . bonus depreciation will be at a rate of 50% ( 50 % ) for 2015 , 2016 and 2017 , 40% ( 40 % ) for 2018 and 30% ( 30 % ) for 2019 . higher net income in 2014 increased cash provided by operating activities compared to 2013 , despite higher income tax payments . 2014 income tax payments were higher than 2013 primarily due to higher income , but also because we paid taxes previously deferred by bonus depreciation . investing activities higher capital investments in locomotives and freight cars , including $ 327 million in early lease buyouts , which we exercised due to favorable economic terms and market conditions , drove the increase in cash used in investing activities in 2015 compared to 2014 . higher capital investments , including the early buyout of the long-term operating lease of our headquarters building for approximately $ 261 million , drove the increase in cash used in investing activities in 2014 compared to 2013 . significant investments also were made for new locomotives , freight cars and containers , and capacity and commercial facility projects . capital investments in 2014 also included $ 99 million for the early buyout of locomotives and freight cars under long-term operating leases , which we exercised due to favorable economic terms and market conditions. .
