These are fixed-income securities that are inflation inde inflatio dexed to EXERCISES 73 protect their value against inflation. Like conventional bonds they have a fixed coupon rate and maturity date, but the face value is periodically adjusted for inflation by multiplying the original face value by the ratio of the Consumer Price Index (CPI) at the current date to the CPI at the original issue date. Each semiannual coupon payment is the inflation-adjusted face value times the fixed coupon rate. At maturity, the bondholder receives the maximum of the inflation-adjusted face value or the original face value. Hence, if deflation occurs the bondholder is guaranteed not to lose on the face value. You observe the following prices of two 10-year inflation-adjusted bonds: Bond 1: P,-77.92, CI--3%, FI 100 Bond 2: P2 100.00, C2 6%, F)-100, where P is the price, C is the coupon rate, and F is the original face value.
