An investor bought two fixed-coupon bonds issued by the same company, a zero-coupon bond and a 7% pa semi-annual coupon bond. Both bonds have a face value of $1,000, mature in 10 years, and had a yield at the time of purchase of 8% pa.

Question 413 CFFA, interest tax shield, depreciation tax shield
There are many ways to calculate a firm's free cash flow (FFCF), also called cash flow from assets (CFFA).
One method is to use the following formulas to transform net income (NI) into FFCF including interest and depreciation tax shields:
###FFCF=NI + Depr - CapEx -ΔNWC + IntExp###
###NI=(Rev - COGS - Depr - FC - IntExp).(1-t_c )###
Another popular method is to use EBITDA rather than net income. EBITDA is defined as:
###EBITDA=Rev - COGS - FC###
One of the below formulas correctly calculates FFCF from EBITDA, including interest and depreciation tax shields, giving an identical answer to that above. Which formula is correct?
A European call option will mature in ##T## years with a strike price of ##K## dollars. The underlying asset has a price of ##S## dollars.

An equity index stands at 100 points and the one year equity futures price is 102.
The equity index is expected to have a dividend yield of 4% pa. Assume that investors are risk-neutral so their total required return on the shares is the same as the risk free Treasury bond yield which is 10% pa. Both are given as discrete effective annual rates.
Assuming that the equity index is fairly priced, an arbitrageur would recognise that the equity futures are:
Telsa Motors advertises that its Model S electric car saves $570 per month in fuel costs. Assume that Tesla cars last for 10 years, fuel and electricity costs remain the same, and savings are made at the end of each month with the first saving of $570 in one month from now.
The effective annual interest rate is 15.8%, and the effective monthly interest rate is 1.23%. What is the present value of the savings?
You just spent $1,000 on your credit card. The interest rate is 24% pa compounding monthly. Assume that your credit card account has no fees and no minimum monthly repayment.
If you can't make any interest or principal payments on your credit card debt over the next year, how much will you owe one year from now?
Question 869 economic order quantity
A Queensland farmer grows strawberries in greenhouses and supplies Australian supermarkets all year round. The farmer must decide how often he should contract the truck driver to deliver his strawberries and how many boxes to send on each delivery. The farmer:

- Incurs holding costs (refrigeration and spoilage) of $16 per box per year; and
- Must pay the truck driver delivery fees at $0.20 per box plus a $500 fixed fee per delivery.

A stock has an expected return of 10% pa and you're 90% sure that over the next year, the return will be between -15% and 35%. The stock's returns are normally distributed. Note that the Z-statistic corresponding to a one-tail:
- 90% normal probability density function is 1.282.
- 95% normal probability density function is 1.645.
- 97.5% normal probability density function is 1.960.
What is the stock’s standard deviation of returns in percentage points per annum (pp pa)?
