The durations of the assets and liabilities are 1.397 years and 0.5535 years, respectively. The debt/equity ratio is 10. What is the leveraged adjusted duration gap (LADG)? If the equity is $20 million, what will the new equity value be if the relative change in interest rates is a decrease of 0.5%? What variables are available for immunization?
Solution) Debt/Equity = 10
Thus, Debt (D) = 10* Equity (E)
D = 10*E
Assets (A) = Debt (D) + Equity (E)
A = 10E + E = 11E
Thus, Debt/Assets = 10E/11E = 10/11
Leveraged adjusted duration gap (LADG) = Da - K*Dl
where Da = Duration of assets =1.397 years
Dl = Duration of liabilities = 0.5535 years
K = Debt/Assets = 10/11
Thus, LADG = 1.397 - 10/11*0.5535
LADG = 1.397 - 0.503182
LADG = 0.893818 years
If Equity (E) = $20 million, then,
Assets = 11*E = 11*20 million = 220 million
Relative change in interest rate = (Change in R)/(1 + R) = -0.5%
where, R is the interest rate
Change in equity value = -LADG*Assets Value*Rlative change in interest rate
Thus, change in equity = -0.893818*220*(-0.5%)
= 0.893818*220*0.005
= 0.9831998 million
Hence, new equity = 20 + 0.9831998 = 20.9831998 million
= 20.98 million
For immunization, the LADG be 0.
Thus, (DA-DL*K) = 0
DA = Dl*K
DA = 0.5535*10/11 = 0.50318 years
