Question: 1. For this question, you will need to look up Boeing's financial statements. This is easy to do on Yahoo Finance (finance.yahoo.com). Look up ticker BA, then click "Financials." You will need the income statement, and focus on the most recent one from 12/31/2015 (note this is the Annual statement, not the quarterly).
a) What was Boeing's effective tax rate (meaning what percentage tax rate did they actually pay)?
b) Use this tax rate to estimate how much Boeing's usage of debt decreased their tax bill in dollars.
c) Assume Boeing issues bonds with an interest rate of 3%. In percentage terms, what is their effective interest rate net of the tax benefits (you can again assume the same tax rate from part a)?
