Your friend wants to borrow $1,000 and offers to pay you back$100 in 6 months, with more $100 payments at the end of every month for another 11 months. So there will be twelve$100 payments in total. She says that 12 payments of $100 equals$1,200 so she's being generous.

If interest rates are 12% pa, given as an APR compounding monthly, what is the Net Present Value (NPV) of your friend's deal?

A wholesale horticulture nursery offers credit to its customers.

Customers are given 60 days to pay for their goods, but if they pay immediately they will get a 3% discount.

What is the effective interest rate implicit in the discount being offered? Assume 365 days in a year and that all customers pay either immediately or on the 60th day. All rates given below are effective annual rates.

A stock pays semi-annual dividends. It just paid a dividend of $10. The growth rate in the dividend is 1% every 6 months, given as an effective 6 month rate. You estimate that the stock's required return is 21% pa, as an effective annual rate. Using the dividend discount model, what will be the share price? The required return of a project is 10%, given as an effective annual rate. What is the payback period of the project in years? Assume that the cash flows shown in the table are received smoothly over the year. So the$121 at time 2 is actually earned smoothly from t=1 to t=2.

 Project Cash Flows Time (yrs) Cash flow ($) 0 -100 1 11 2 121 Which statement about risk, required return and capital structure is the most correct?  Portfolio Details Stock Expected return Standard deviation Correlation $(\rho_{A,B})$ Dollars invested A 0.1 0.4 0.5 60 B 0.2 0.6 140 What is the standard deviation (not variance) of the above portfolio? A three year corporate bond yields 12% pa with a coupon rate of 10% pa, paid semi-annually. Find the effective six month yield, effective annual yield and the effective daily yield. Assume that each month has 30 days and that there are 360 days in a year. All answers are given in the same order: $r_\text{eff semi-annual}$, $r_\text{eff yearly}$, $r_\text{eff daily}$. A stock has a beta of 1.5. The market's expected total return is 10% pa and the risk free rate is 5% pa, both given as effective annual rates. Over the last year, bad economic news was released showing a higher chance of recession. Over this time the share market fell by 1%. So $r_{m} = (P_{0} - P_{-1})/P_{-1} = -0.01$, where the current time is zero and one year ago is time -1. The risk free rate was unchanged. What do you think was the stock's historical return over the last year, given as an effective annual rate? One year ago you bought a$1,000,000 house partly funded using a mortgage loan. The loan size was $800,000 and the other$200,000 was your wealth or 'equity' in the house asset.

The interest rate on the home loan was 4% pa.

Over the year, the house produced a net rental yield of 2% pa and a capital gain of 2.5% pa.

Assuming that all cash flows (interest payments and net rental payments) were paid and received at the end of the year, and all rates are given as effective annual rates, what was the total return on your wealth over the past year?

Hint: Remember that wealth in this context is your equity (E) in the house asset (V = D+E) which is funded by the loan (D) and your deposit or equity (E).

Below is a table of the 'Risk-weights for residential mortgages' as shown in APRA Basel 3 Prudential Standard APS 112 Capital Adequacy: Standardised Approach to Credit Risk January 2013.

A bank is considering granting a home loan to a man to buy a house worth \$1.25 million using his own funds and the loan. The loan would be standard with no lenders mortgage insurance (LMI) and an LVR of 80%.

What is the minimum regulatory capital that the bank requires to grant the home loan under the Basel 3 Accord? Ignore the capital conservation buffer.
