Remarks

The discount rate is the interest rate implied when a security is sold for less than its value at maturity in lieu of interest payments. It is computed using the following:

{{{{\it redemption} - {\it price}} \over {\it price}}} \times {{B \over {\it DSM}}}
In the equation above, B represents the number of days in a year based on the annual basis and {\it DSM} represents the number of days starting with the settlement date and ending with the maturity date.
