Guideline Answer:
■ The module that should be selected for each goal is the one that offers the highest return given the time horizon and required probability of success.
■ Approximately 16.4%, 12.7%, 50.4%, and 20.5% should be invested in Modules A, B, C, and D, respectively. The appropriate goals-based allocation for the Armstrongs is as follows:
Supporting calculations:
For Goal 1, which has a time horizon of five years and a required probability of success of 85%, Module C should be chosen because its 4.4% expected return is higher than the expected returns of all the other modules. The present value of Goal 1 is calculated as follows:
N = 5, FV = –5,000,000, I/Y = 4.4%; CPT PV = $4,031,508 (or $4.03 million)
So, approximately 50.4% of the total assets of $8 million (= $4.03 million/$8.00 million) should be allocated to Module C.
For Goal 2, which has a time horizon of 10 years and a required probability of success of 99%, Module B should be chosen because its 2.2% expected return is higher than the expected returns of all the other modules. The present value of Goal 2 is calculated as follows:
PV=$100,000/(1.022)1+$100,000(1.03)1/(1.022)2+$100,000(1.03)2/(1.022)3+...+$100,000(1.03)9/(1.022)10
PV = $1,013,670 (or $1.01 million)
So, approximately 12.7% of the total assets of $8 million (= $1.01 million/$8.00 million) should be allocated to Module B.
For Goal 3, which has a time horizon of 25 years and a required probability of success of 75%, Module D should be chosen because its 7.5% expected return is higher than the expected returns of all the other modules. The present value of
Goal 3 is calculated as follows:
N = 25, FV = –10,000,000, I/Y = 7.5%; CPT PV = $1,639,791 (or $1.64 million)
So, approximately 20.5% of the total assets of $8 million (= $1.64 million/$8.00 million) should be allocated to Module D.
Finally, the surplus of $1,315,032 (= $8,000,000 – $4,031,508 – $1,013,670 –$1,639,791), representing 16.4% (= $1.32 million/$8.00 million), should be invested in Module A following Abbott’s suggestion.
老师,首先请帮忙看一下我的答案这样写OK吗?
According to the answer of last question, we should choose module C for goal 1, module B for goal 2 and module D for goal3.
We should calculate the present value of these liabilities first with the expected returns of each portfolio.
For goal 1: PV=5/(1+4.4%)^5=4.03 million
For goal 2: PV=0.1/(1+2.2%)+0.1*(1+3%)/(1+2.2%)^2+……=1.01million
For goal 3: PV=10/(1+7.5%)^25=1.64million
Total amount equals to 6.68million
The residual capital is 1.32million and should be allocated to module A as Abbott suggests. In conclusion the overall capital allocation weights are 16.5%for module A, 12.6% for module B, 50.4% for module C and 20.5% for sub-portfolio D.
就是写的比较简练,没有答案中那么长,再一个就是我最后算出来的占比和答案存在0.01%的尾差,考试的时候会扣分吗?谢谢!
