An investor buys a 9-year, 6.9% annual coupon bond at par ($100). After the purchase and before the first coupon is received, interest rates increase to 8.9% (assume a flat spot rate curve). The investor sells the bond after 7 years (right after receiving the 7th coupon payment). What is this investor's realized annual return in these 7 years?

Assume annual compounding, and that interest rates remain at 8.9% over the entire holding period.
