A corporate bond with a 3.95% coupon has 21 years left to maturity. It has had a credit rating of BBB and a yield to maturity of 5.35%. The firm has recently gotten into some trouble and the rating agency is downgrading the bonds to BB. The new appropriate discount rate for a bond with this level of credit risk and time to maturity is 6.55%.

What will be the net change in the bonds price in dollars if this rating downgrade and associated new discount rate occurred today? (Assume interest payments are semiannual; round and display your answer to 2 decimal places i.e. 1.23)
