Goodwynn & Wolf Incorporated (G&W) issued a bond 6 years ago. The bond had a 17-year maturity, a 12% coupon paid annually, a 7% call premium and was issued at par, $1,000. Today, G&W called the bonds. If the original investors had expected G&W to call the bonds in 6 years, what was the yield to call at the time the bonds were issued? Round your answer to two decimal places.

Thank You.
