Last year Janet purchased a $$1,000$ face value corporate bond with a $12\%$ annual coupon rate and a $10-$year maturity. At the time of the purchase, it had an expected yield to maturity of $9\mathrm{.}36\%.$ If Janet sold the bond today for $$1,172\mathrm{.}66,$ what rate of return would she have earned for the past year? Do not round intermediate calculations. Round your answer to two decimal places.
