The equations for Net Income (NI, also known as Earnings or Net Profit After Tax) and Cash Flow From Assets (CFFA, also known as Free Cash Flow to the Firm) per year are:

###NI=(Rev-COGS-FC-Depr-IntExp).(1-t_c)###

###CFFA=NI+Depr-CapEx - \varDelta NWC+IntExp###

For a firm with debt, what is the formula for the present value of interest tax shields if the tax shields occur in perpetuity?

You may assume:

the value of debt (D) is constant through time,
The cost of debt and the yield on debt are equal and given by ##r_D##.
the appropriate rate to discount interest tax shields is ##r_D##.
##\text{IntExp}=D.r_D##

Question 300 NPV, opportunity cost

What is the net present value (NPV) of undertaking a full-time Australian undergraduate business degree as an Australian citizen? Only include the cash flows over the duration of the degree, ignore any benefits or costs of the degree after it's completed.

Assume the following:

The degree takes 3 years to complete and all students pass all subjects.
There are 2 semesters per year and 4 subjects per semester.
University fees per subject per semester are $1,277, paid at the start of each semester. Fees are expected to remain constant in real terms for the next 3 years.
There are 52 weeks per year.
The first semester is just about to start (t=0). The first semester lasts for 19 weeks (t=0 to 19).
The second semester starts immediately afterwards (t=19) and lasts for another 19 weeks (t=19 to 38).
The summer holidays begin after the second semester ends and last for 14 weeks (t=38 to 52). Then the first semester begins the next year, and so on.
Working full time at the grocery store instead of studying full-time pays $20/hr and you can work 35 hours per week. Wages are paid at the end of each week and are expected to remain constant in real terms.
Full-time students can work full-time during the summer holiday at the grocery store for the same rate of $20/hr for 35 hours per week.
The discount rate is 9.8% pa. All rates and cash flows are real. Inflation is expected to be 3% pa. All rates are effective annual.

The NPV of costs from undertaking the university degree is:

Question 467 book and market values

Which of the following statements about book and market equity is NOT correct?

(a) The market value of equity of a listed company's common stock is equal to the number of common shares multiplied by the share price.

(b) The book value of equity is the sum of contributed equity, retained profits and reserves.

(c) A company's book value of equity is recorded in its income statement, also known as the 'profit and loss' or the 'statement of financial performance'.

(d) A new company's market value of equity equals its book value of equity the moment that its shares are first sold. From then on, the market value changes continuously but the book value is recorded at historical cost which typically only changes due to retained profits.

(e) To buy all of the firm's shares, generally a price close to the market value of equity will have to be paid.

Question 628 CAPM, SML, risk

Assets A, B, M and ##r_f## are shown on the graphs above. Asset M is the market portfolio and ##r_f## is the risk free yield on government bonds. Assume that investors can borrow and lend at the risk free rate. Which of the below statements is NOT correct?

Question 724 return distribution, mean and median returns

Question 746 pay back period

A stock is expected to pay a dividend of $1 in one year. Its future annual dividends are expected to grow by 10% pa. So the first dividend of $1 is in one year, and the year after that the dividend will be $1.1 (=1*(1+0.1)^1), and a year later $1.21 (=1*(1+0.1)^2) and so on forever.

Its required total return is 30% pa. The total required return and growth rate of dividends are given as effective annual rates. The stock is fairly priced.

Calculate the pay back period of buying the stock and holding onto it forever, assuming that the dividends are received as at each time, not smoothly over each year.

Adam can pick 7 coconuts per hour, 6 dates per hour or any linear combination of coconuts and dates. For example, he could pick 3.5 coconuts and 3 dates per hour.

Bella can pick 3 coconuts per hour, 5 dates per hour or any linear combination. For example, she could pick 1.5 coconuts and 2.5 dates per hour.

This information is summarised in the table and graph:

Harvest Rates Per Hour
