Financial arithmetic: The time value of money Bond prices are expressed ‘per 100 nominal’ – that is, as a percentage of the bond’s face value. 00, this means that for every $100 of the bond’s face value, a buyer would pay $98. The principles of pricing in the bond market are the same as those in other financial markets: the price of a financial instrument is equal to the sum of the present values of all the future cash flows from the instrument. The interest rate used to derive the present values of the cash flows, known as the discount rate, is key, since it reflects where the bond is trading and how its return is perceived by the market.

This process of calculation and adjustment up or down is repeated until the estimates converge on a level that generates the bond’s current price. To differentiate redemption yield from other yield and interest-rate measures described in this book, it will be referred to as rm.
