BOND VALUATION

Solution:

Since the bond pays 10% on $5,000 semiannually, the regular interest payment will be:

 

                                           R = F * r

                                               

                                               = $5,000[0.1 / 2]

 

                                               = $250

 

From the information given, the remaining number of interest periods is:

                 

                                     N=10*2, or 20

 

The redemption value of the bond in ten years is the par value or the face value of the bond:

 

                                  RD = $5,000

 

Now to compute the purchase price, we must calculate the present values of the payments and the redemption value. Since the yield rate is the rate the investor wants to receive, it is the rate we must use to find the present values in determining the purchase price. Substituting the values into our formula, we have:

 

 PP = $250[1-(1+i) ^ -n]

          ------------------------ + $ 5,000(1+i) ^ -n

                       I    

     (the payments part of the     + (the redemption part of the

                    formula)                           formula)

 

 

                Substituting the remaining values gives:

                          I = 0.12 /2, or 0.06              yield rate

 

                         N= 20

 

 

      PP= $250[1-(1+0.06) ^ -20]

             ------------------------------ + $5,000(1+0.06) ^ -20

                            0.06

 

                        PP = $2,867.50 +$1,559.02

 

                        PP (purchase price) = $4,426.52

 

 

How to calculate the Purchase Price of a Bond, if it is purchased between interest dates:

 

Most bond sales occur between interest dates.

 

Example: Consider the same example given above. Assume the bond is purchased 156 days after April 1 (the interest date).    

 

Then the purchase price would be:

 

      $ 4,426.52   [1 + 0.06(156/183)]            

(as calculated in the above example)

 

                    PP = $ 4,652.93

 

The issuer may at the time of issue of the bonds commit to redeem the bonds at a premium. Assume that in the above example the bonds are to be redeemed at 102; this means that for every dollar of face value, $ 1.02 will be paid upon redemption.

 

The reason an issuer may offer such an arrangement is to encourage people to buy the bond and hold until it is redeemed. To this investor this represents a slight increase in the return. In the above example, the $5,000 bond would be redeemed at $5,100. To calculate the purchase price, replace the $5,000 considered in the redemption value of the formula by $ 5,100.
