Exercise on Bond valuation



Gain Allah (Subhana wa ta ‘ala) pleasure, and worshiping is the utmost reason of existence of human being on earth, we shall continue glorifying him alone. May the peace and salutations of Allah subhana watala be upon the beloved prophet Muhammad (Salal Allahu Alahe wa salam)  his family and the righteous guided Sahabas.


1.      (A) SECTION  (i) Semiannual base
FV= 1000
PMT= 0.09*1OOO= 90/2= 45
N= 10*2= 20 Years
I= 10%=10%/2= 5% OR 0.05

PV= PMT/I*[ 1-1/ (1+I)^N] +FV/(1+I)^N
PV= 45/0.05*[1-1(1+0.05)^20]+1000/(1+0.05)^20
PV= 560.7995 + 376.8895
PV= 937.6890

The result are shown in the table below:

1.      (A) (ii) 
FV= 1000

N= 20 Years
I= 7%  = 7%/2 = 3.5 Or 0.035

PV= 45/0.035*[1-1/C1+0.035)^20] +1000/(1+0.035)^20
PV= 639.5581 + 502.5659

1.      (A) (iii)
FV=100
N= Issue 8 Years
PMT= 100*0.19 =19
I= 18.77%
PV= 100.917
PV= PMT/I*[1-1/(1+I)^N]+FV/(I+I)^N

Note: I have made several trials but 18.77 is the closest to PV= 100.9159. Let i= 18.77%
PV= 19/0.1877*[1-1/(1+0.1877)^8]+ FV/(1+0.1877)^8
PV= 75.6610 +25.2549
PV= 100.9159
.
The results are summarizing in the table below.

(B)  SECTION (I ) What is a callable bond? These are bond that  give or allow the issuer the right to be pensioned off the debt, completely or incompletely, formerly the scheduled maturity date.
      (B) (ii) who gain from the call option..? the Bond with a call option is benefiting or  in other word is  good for the issuer in a condition that, the interest rates drop, and the bond with a call option must be  sell at a lesser price for the reason that the call provision is more appreciable to the firm, not for the holder of the bond.

       (B) (iii) The price and yield of the two identical bonds, the Investors pay a lesser amount for a callable bond as compared to the non-callable bond. As a result, the yield to maturity must be greater on the callable bond then non-callable bond.


(C)      SECTION
The Interest Rate= 12.95% = 0.1295
 Monthly =  [1+ i/12]^12 -1
                = [ 1+o.1295/12]^12 -1
                = 1.137470-1
                =0.13747 Or 13.747%
The result  is as shown in the below:

Interest (I)     
12.95%
Monthly
12
Monthly Interest rate Charge
13.747%


The Interest Rate= 12.95% = 0.1295
Effective Annual Rate= [1+0.1295]-1
                                      = 1.1295-1
                                     = 0.1295
                                    = 12.95%
The result is shown in the table below:

Interest (I)
12.95%
Effective Annual Rate (EAR)
12.95%



(D)  SECTION
Decided to buy Sofa for=  $109
Sale person offer to divide payment over 12 months without interest= $170/12 +Admin fee ($5)
 If the alternative is to choose the credit card with APR of 12%

SOLUTION

(i)                 The amounts pay for sofa without interest. = $170/12 = 14.1667 +Admin Fee ($5)
                                                                               = $14.1667 +$5
                                                                               = $19.1667

The amount pays for sofa with interest = EAR =[1+ rNom/M]^m -1
                                                                       = [1+0.12/12]^12 -1
                                                                      = 1.126825-1
                                                                      = 0.126825 Or 12.6825
                                                                      = $12.6825
(ii)               If I am to choose the payment type I will choose, the Credit Card this is because the Credit Card has lesser cause As compared to the At the store the sales person offers .
The credit Card  causes this (12.6825%), and the store the sales person offers (19.17%).

The results are  summarized in the table below:
Payments methods A

Payments methods B
Administrative fee Charge per month

(i)                 Which of the bond from A to D will be sensitive to  a 1% drop interest rate from 6% to 5% and why..?
(ii)               Which bond id least sensitive provide intuitive explanation..?
SOLUTION

(i)                 Which bond is more sensitive to drop TYM Or Interest from 6% to 5%
Less first and foremost take the bond of each TYM using the face value of 1.(A)(1) with 6% of TYP and the face value of  1000 in 1.(A) I will be using it throughout..
To find the price of a bond:
YTM =6%

We used the formula PV= PMT/I*[1-1/(1+I)^N]+FV/(1+I)^N
{Bond A, 6% YTM}= 0/*[1-1/(1+0.06)^15]+1000/(1+0.06)^15
                                = 0  + 417.2651    =417.2651

 {Bond B, 6% YTM}=0/0.06*[1-1/(1+0.06)^10]+1000/(1+0.06)^10
                                 =0+ 558.3948 = 558.3948

 {Bond C, 6% YTM}=4/0.06*[1-1/(1+0.06)^15]+1000/(1+0.06)^15
                                 = 38.8490+ 417.2650  =456.1141
{Bond D, 6% YTM}=8/0.06*[1-1/(1+0.06)^10]+1000/(1+0.06)^10
                                 =58.8810+558.3948
                                =617.27577   =617.2758
YTM =5%
{Bond A, 5% YTM}= 0/*[1-1/(1+0.05)^15]+1000/(1+0.05)^15
                                 = 0+ 481.0171  =481.0171

{Bond B, 5% YTM}=0/0.05*[1-1/(1+0.05)^10]+1000/(1+0.05)^10
                                = 0+ 613.9133      =613.9133

{Bond C, 5% YTM}=4/0.05*[1-1/(1+0.05)^15]+1000/(1+0.05)^15
                               =41.5186 + 481.0171   = 522.5357
 {Bond D, 5% YTM}=8/0.05*[1-1/(1+0.05)^10]+1000/(1+0.05)^10
                                 = 61.7739 + 613.9133     =675.6872

Now we can compute the price of each YTM, the percentage price change as:

Percentage change = (Price at 5% of YTM)- (Price at 6% of YTM)/ (Price at 6% of YTM)
{Percentage of bond A} =(481.0171-417.2651)/( 417.2651) = 15.2785%
{Percentage of bond B} =( 613.9133 -558.3948)/(558.3948) = 9.9425%
{Percentage of bond C} = (522.5357-456.1141)/( 456.1141)  = 14.5625%
{Percentage of bond D} = (675.6872 -617.2758)/( 617.2758) = 9.4628%

The results are shown in the table below:

(i)                 Which of the bond from A to D will be sensitive to  a 1% drop interest rate from 6% to 5% and why..? Bond A is most sensitive, this is because it has the lengthiest or longest maturity and no coupons rate.
(ii)               The bond D is the lowest or least sensitive to drop the interest. Therefore Intuitively, the greater coupon rates and a smaller the maturity characteristically lowered a bond’s interest rate sensitivity.

The roots of the feminist movement in the West and its harmful effect on Western society, with special emphasis on how it has harmed the concept of marriage a few steps that Muslims can take to protect the ummah from the harmful elements of feminism.
