Interest rates are a function of three key things (check slides if you aren't sure what this is!).

Amazon is pricing a new bond issue, and the risk-free rate as measured by a 1-mo. US T-bill is 3.2%. The duration of the bond issue will be 10 years. The spread between a 10-year US Treasury bond and 1-mo US T-bill is 2.2%. Finally, Amazon is A rated and US Treasury bills are AAA rated. The spread between yields on A and AAA bonds is 1.3%. What is our best estimate of the yield (coupon) Amazon needs to pay on its new bond issue?
