    All students must hand in an assignment of their own. Ensure you also complete and
    attach a cover sheet with your assignment. You must complete the assignment using a
    spreadsheet. Assignments should be submitted using wattle and should have the answer
    and workings set out in a way, which is easy to follow. For your assignment submission
    make sure you add a worksheet to your excel file which has all the answers summarized
    and workings must be shown on separate worksheets.

    The Scenario
    You are a financial planner who is investigating the options for a 45-year old man who
    wishes to have enough money to retire by the time he is 65. The man has just turned 45
    and has received a sizable inheritance of $150,000. He has approached you to understand
    his financial situation and make an informed decision regarding his investment options
    for his financial future. His current financial arrangements are as follows:
    • His salary has just been increased to $120,000 p.a., which is taxed at a rate of 33%
    before being paid to him. This is currently being paid on a monthly basis at the
    start of each month.
    • Any salary over $200,000 p.a. will be taxed at 40% (i.e. the first $200,000 p.a. of
    salary is taxed at 33%, the amount over $200,000 p.a. is taxed at 40% - tax is paid
    at a constant rate each month during each year assuming that the monthly salary
    is to be earned over the whole year).
    • He is paying off a mortgage on the property he lives in. The payments are currently
    $3,000 at the end of each month, which is enough to have the property paid off
    exactly in 7 years at the current interest rate of 4% p.a. effective.
    • Currently each month, $2,500 of his net salary is being used in expenses and any
    additional amount is being invested in a bank account earning 2.5% p.a.
    compounded monthly. These payments are being made on the same day the net
    salary is received.
    • The current bank account balance (before receiving the inheritance) can be
    assumed to be zero.
    • He expects his expenses to increase by 0.6% each month.
    • He expects his salary to increase at a rate of 5% p.a. going forward. This increase
    is processed on a yearly basis, with the next increase to occur after 12 further
    salary payments at the recently increased rate.
    • Interest income in the bank account is taxed at a concessional rate of 15%
    immediately on the interest income earned each month.
    • He intends to live in his home when he is retired and live off the proceeds of his
    bank account in retirement.
    • Initially, the man wants to deposit the inheritance in his bank account.
    a) Calculate the expected amount the man will have in his bank account at age
    65 under the basis above. Assume all interest rates remain constant.

    The first thing you notice about this man’s financial affairs is that it would most likely be
    beneficial for him to pay off the mortgage as quickly as possible. This would involve using
    the inheritance immediately and making a lump sum contribution to the home loan, and
    then continuing the $3,000 per month repayments until the loan is paid off. Any
    additional amount of salary not used is credited to the bank account.
    b) Calculate how much more the man will have at age 65 if he takes this
    approach.
    (7 Marks)
    The client mentions to you he is extremely risk averse and does not want to invest in
    anything where the cash-flows aren’t known in advance. Based on this you decide to only
    recommend fixed interest securities, with the intention of investigating the impact of
    investing the inheritance in either of these securities.
    Two options which you are considering are as follows:
    Bond A – A zero coupon bond redeemable in 20 years with a gross yield of 6.0% p.a.
    effective.
    Bond B – Pays half yearly coupons of 6.0% p.a. Redemption is at the decision of the issuer
    at the following redemption values:
    • 1.2 times the face value on any coupon date in the 11 th year through to the 13 th
    year from now
    • 1.3 times the face value on any coupon date in the 14 th year through to the 15 th
    year from now
    This bond has a minimum gross yield of 7.5% p.a. effective.
    c) Assuming the man invests in either Bond A or Bond B (but not both at the
    same time); calculate the nominal amount of each bond which can be
    purchased using the inheritance amount of $150,000.

    Should the client decide to invest in one of the bonds above, you decide to recommend
    that the mortgage continue to be paid off with the $3,000 per month for 7 years. The client
    is also subject to a tax of 20% on coupons and capital gains. The tax is payable
    immediately it is incurred, with coupons to be invested in the bank account when they
    are received. The gross yields of the bonds are unchanged.
    d) For both bond purchase options, calculate how much money the man will
    have in the bank account at age 65. Assume that Bond B is redeemed at the
    end of the 15 th year.
    (14 marks)
    e) Which of the four alternatives discussed above should the man choose such
    that he has the largest bank balance at the age of 65? Give a short
    explanation for your answer.
