CSX Corp., decomposition of ROE

Microsoft Excel LibreOffice Calc
ROE = ROA × Financial Leverage
Dec 31, 2018 hidden = hidden × hidden
Dec 31, 2017 hidden = hidden × hidden
Dec 30, 2016 hidden = hidden × hidden
Dec 25, 2015 hidden = hidden × hidden
Dec 26, 2014 hidden = hidden × hidden

Based on: 10-K (filing date: 2019-02-06), 10-K (filing date: 2018-02-07), 10-K (filing date: 2017-02-14), 10-K (filing date: 2016-02-10), 10-K (filing date: 2015-02-11).

The primary reason for the decrease in return on equity ratio (ROE) over 2018 year is the decrease in profitability measured by return on assets ratio (ROA).
