A 7-year, 5 percent coupon bond has a yield to maturity of 4 percent. A portfolio manager with a four-year horizon needs to forecast the total return on the bond over the coming four years. In four years, the yield to maturity on this bond is expected to be 5 percent and the coupon payments can be reinvested in short term securities at a rate of 2, 2.5, 3, and 3.5 percent respectively for the next four years. Calculate the estimated annualized return based on these predictions
