Your company issues $20-$year bonds that make one coupon payment per year. The bonds have

a face value of $$1,000$ and a coupon rate of $11\%.$ The bonds also have a call feature allowing

your firm to call in the bonds $6$ years after the date of issue, at $103\%$ of par. Assume that the

yield to maturity is $9\%$ at the date of issue.

If the bond is called in $6$ years after the issue date, what is the yield to call?
