* Using the yields given, estimate the value of an annuity that pays $1000 every five years over the next 25 years (e.g., five total payments) paid by either the U.S. Department of the Treasury, Microsoft, CVS, or Boeing. * Calculate the implied yield to maturity for each security. Note: While the yields you have are for coupon bonds, because coupon rates are relatively low, you decide to treat them as zero-coupon yields for this estimation, as you feel the estimation error from such an approximation is small relative to the other noise in the data.
