Show yourcalculations.Show your calculations. Guiline Answer:■ The mole thshoulselectefor eagois the one thoffers the highest return given the time horizon anrequireprobability of success.■ Approximately 16.4%, 12.7%, 50.4%, an20.5% shoulinvestein Moles an respectively. The appropriate goals-baseallocation for the Armstrongs is follows:Supporting calculations:For Go1, whiha time horizon of five years ana requireprobability of success of 85%, Mole C shoulchosen because its 4.4% expectereturn is higher ththe expectereturns of all the other moles. The present value of Go1 is calculatefollows: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 totassets of $8 million (= $4.03 million/$8.00 million) shoulallocateto Mole For Go2, whiha time horizon of 10 years ana requireprobability of success of 99%, Mole B shoulchosen because its 2.2% expectereturn is higher ththe expectereturns of all the other moles. The present value of Go2 is calculatefollows: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)10PV = $1,013,670 (or $1.01 million)So, approximately 12.7% of the totassets of $8 million (= $1.01 million/$8.00 million) shoulallocateto Mole For Go3, whiha time horizon of 25 years ana requireprobability of success of 75%, Mole shoulchosen because its 7.5% expectereturn is higher ththe expectereturns of all the other moles. The present value ofGo3 is calculatefollows: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 totassets of $8 million (= $1.64 million/$8.00 million) shoulallocateto Mole 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), shoulinvestein Mole A following Abbott’s suggestion. 老师，首先请帮忙看一下我的答案这样写OK吗？Accorng to the answer of last question, we shoulchoose mole C for go1, mole B for go2 anmole for goal3.We shoulcalculate the present value of these liabilities first with the expectereturns of eaportfolio.For go1: PV=5/(1+4.4%)^5=4.03 millionFor go2: PV=0.1/(1+2.2%)+0.1*(1+3%)/(1+2.2%)^2+……=1.01millionFor go3: PV=10/(1+7.5%)^25=1.64millionTotamount equals to 6.68millionThe resicapitis 1.32million anshoulallocateto mole A Abbott suggests. In conclusion the overall capitallocation weights are 16.5%for mole 12.6% for mole 50.4% for mole C an20.5% for sub-portfolio 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！
