I was quickly investigating Boeing's (BA) Debt-to-Equity ratio and received a very high number. I looked around online and have confirmed that BA has recently taken on a lot of debt, but am not reaching the same calculations as Morningstar or YCharts.
2016 Annual Debt: 89120.0
2016 Annual Shareholder Equity: 877.0
Debt-to-Equity = 89120 / 877 = 101.6
Ycharts shows a Debt-to-Equity ratio of [12.01]. This should be a simple calculation so how am I getting different numbers?
