In October 2010, EBay issued 1.5 billion dollars bond notes to raise capital. The bonds were issued 3 distributions. The first notes were $400 million with a 3 years duration with a coupon rate of 0875%. The second notes were a total of $600 million with a duration of 5 years with a coupon rate of 1.625%. The third issue of notes were $500 million with a duration of 10 years and a coupon rate of 3.25%. If I originally invested $10,000 what would my total return be if I sold at today's market price?  also include the current duration of the bond.
