[Planned expenses]

- Paul’s daughter is now 6 years old and he plans to send her to atop local university in 12 years.
Currently, the cost of studying (tuition fees and living expenses)is $150,000 per year, but it is
expected to increase with the inflation rate of 3% per year. Ittakes his daughter 4 years to
complete her undergraduate study, and it is assumed that he willhave to pay the tutition fees
and living expenses for his daughter on his 55th, 56th, 57th and58th birthdays.

- Besides, he would need $2,000,000 to take his wife for around-the-world trip at their 30th
anniversary when he reaches 62.

- Paul is planning to retire at the age of 65. He estimates that hewill need $30,000 a month to
enjoy his retirement years with his wife, with the first withdrawalon his 65th birthday and the
last withdrawal on his 90th birthday.

- He would also like to donate $40,000 semiannually to hisuniversity, starting from his 70th
birthday through the 80th birthday.

- He plans to leave $10,000,000 to his family at his 90thbirthday.

[Planned savings and cash inflows]
- Eight years ago, Paul joined his employer’s retirement plan thatpaid him 6% interest
(compounded monthly). At the end of each month, he deposited $5,000into the retirement
account. He is planning to move all the funds from his retirementaccount to a high-yield
savings account after he made the last deposit today.

- In addition, he plans to make a quarterly deposit to thehigh-yield savings account, with the
first deposit to be made a quarter from today and the last depositone year before his retirement
(i.e. on his 64th birthday). He expects to earn a quarterly returnof 3.7971% from the high-yield
account. When he retires, he will have to move all his money to alow-risk account that enables
him to withdraw money whenever he needs. It is expected that thelow-risk account will pay
him an interest of 2% (compounded semiannually).

- He expects to stay in his company until he retires and receive aloyalty bonus of $80,000 at his
60th birthday. The loyalty bonus will be deposited to thehigh-yield account as well.
