mentione Ibarra is consiring a future interest rate volatility of 20% and
upwarsloping yielcurve, shown in Exhibit 2.
Baseon her analysis, the fair value of bonis closest to:
€1,101.24.
€1,141.76.
€1,144.63.
A is correct.
The following tree shows the valuation assuming no fault of bonB2, which
pays a 6% annucoupon.
The scheled
year-encoupon anprincippayments are placeto the right of eaforwarrate in the tree. For example, the te 4 values are
the principplus the coupon of 60. The following are
the four te 3 values for the bon shown above the interest rate each
no:
€1,060/1.080804
= €980.75
€1,060/1.054164
= €1,005.54
€1,060/1.036307
= €1,022.86
€1,060/1.024338
= €1,034.81
These are the
three te 2 values:
(0.5�980.75+0.5�1005.54)+60
1.043999
=1008.76
(0.5�1005.54+0.5�1022.86)+60
1.029493
=1043.43
(0.5�1022.86+0.5�1034.81)+60
1.019770
=1067.73
These are the
two te 1 values:
(0.5�1008.76+0.5�1043.43)+60
1.021180
=1063.57
(0.5�1043.43+0.5�1067.73)+60
1.014197
=1099.96
This is the te
0 value:
(0.5�1063.57+0.5�1099.96)+60
0.997500
=1144.63
So, the value
of the bonassuming no fault (VN is 1,144.63. This value coulalso have
been obtainemore rectly using the benchmark scount
factors from Exhibit 2:
€60 × 1.002506 +
€60 × 0.985093 +
€60 × 0.955848 +
€1,060 ×
0.913225 = €1,144.63.
The benefit of
using the binomiinterest rate tree to obtain the VNis ththe same tree
is useto calculate the expecteexposure to fault
loss. The cret valuation austment table is now prepared
following these steps:
Step 1: Compute
the expecteexposures scribein the following, using the binomiinterest rate tree prepareearlier.
The expected
exposure for te 4 is €1,060.
The expected
exposure for te 3 is
[(0.1250 × €980.75) +
(0.3750 × €1,005.54) +
(0.3750 × €1,022.86) +
(0.1250 × €1,034.81)] + 60 = €1,072.60.
The expected
exposure for te 2 is
[(0.25 × €1,008.76) +
(0.50 × €1,043.43) +
(0.25 × €1,067.73)] + €60 = €1,100.84.
The expected
exposure for te 1 is
[(0.50 × €1,063.57) + (0.50
× €1,099.96)] + 60
= €1,141.76.
Step 2: LG=
Exposure × (1 – Recovery rate)
Step 3: The
initiPO also known the hazarrate, is provi1.50%. For
subsequent tes, POis calculatethe hazarrate multiplied
the previous tes’ POS.
For example, to
termine the te 2 PO(1.4775%), the hazarrate (1.5000%) is multipliethe te 1 POS (98.5000%).
Step 4: POS is
terminesubtracting the hazarrate from 100% anraising it to the power of the number of years:
(100% – 1.5000%)1 = 98.5000%
(100% – 1.5000%)2 = 97.0225%
(100% – 1.5000%)3 = 95.5672%
(100% – 1.5000%)4 = 94.1337%
Step 5:
Expecteloss = LG× POD
Step 6:
scount factors () in YeT are obtainefrom Exhibit 2.
Step 7: PV of
expecteloss = Expecteloss ×
Fair value of
the bonconsiring CVA = €1,144.63 – CVA = €1,144.63 – €43.39 = €1,101.24.
考试的时候，一般情况下可以用表3图来计算吗？还是必须得用表2先推导出每一个节点的利率？
