Discounted Cash Flow Questions & Answers – Advanced

Question 1

Explain why we would use the mid-year convention in a DCF.

Answer 1

You use it to represent the fact that a company’s cash flow does not come 100% at the
end of each year – instead, it comes in evenly throughout each year.

In a DCF without mid-year convention, we would use discount period numbers of 1 for the first year, 2 for the second year, 3 for the third year, and so on.

With mid-year convention, we would instead use 0.5 for the first year, 1.5 for the second year, 2.5 for the third year, and so on.

Question 2

What discount period numbers would I use for the mid-year convention if I have a
stub period – e.g. Q4 of Year 1 – in my DCF?

Answer 2

The rule is that you divide the stub discount period by 2, and then you simply subtract
0.5 from the “normal” discount periods for the future years.

Question 3

How does the terminal value calculation change when we use the mid-year
convention?

Answer 3

When you’re discounting the terminal value back to the present value, you use different
numbers for the discount period depending on whether you’re using the Multiples
Method or Gordon Growth Method:

• Multiples Method: You add 0.5 to the final year discount number to reflect the
fact that you’re assuming the company gets sold at the end of the year.

• Gordon Growth Method: You use the final year discount number as is, because
you’re assuming the cash flows grow into perpetuity and that they are still
received throughout the year rather than just at the end.

Question 4

If I’m working with a public company in a DCF, how do I calculate its per-share value?

Answer 4

Once you get to Enterprise Value, ADD cash and then subtract debt, preferred stock,
and noncontrolling interest (and any other debt-like items) to get to Equity Value.

Then, you need to use a circular calculation that takes into account the basic shares
outstanding, options, warrants, convertibles, and other dilutive securities. It’s circular
because the dilution from these depends on the per-share price – but the per-share price
depends on number of shares outstanding, which depends on the per-share price.

To resolve this, you need to enable iterative calculations in Excel so that it can cycle
through to find an approximate per-share price.

Question 5

Walk me through a Dividend Discount Model (DDM) that you would use in place
of a normal DCF for financial institutions.

Answer 5

The mechanics are the same as a DCF, but we use dividends rather than free cash flows:

1. Project out the company’s earnings, down to earnings per share (EPS).
2. Assume a dividend payout ratio – what percentage of the EPS actually gets paid
   out to shareholders in the form of dividends – based on what the firm has done
   historically and how much regulatory capital it needs.
3. Use this to calculate dividends over the next 5-10 years.
4. Do a check to make sure that the firm still meets its target Tier 1 Capital and
   other capital ratios – if not, reduce dividends.
5. Discount the dividend in each year to its present value based on Cost of Equity –
   NOT WACC – and then sum these up.
6. Calculate terminal value based on P / BV and Book Value in the final year, and
   then discount this to its present value based on Cost of Equity.
7. Sum the present value of the terminal value and the present values of the
   dividends to get the company’s net present per-share value.

Question 6

When you’re calculating WACC, let’s say that the company has convertible debt. Do
you count this as debt when calculating Levered Beta for the company?

Answer 6

Trick question. If the convertible debt is in-the-money then you do not count it as debt
but instead assume that it contributes to dilution, so the company’s Equity Value is
higher. If it’s out-of-the-money then you count it as debt and use the interest rate on the
convertible for Cost of Debt.

Question 7

We’re creating a DCF for a company that is planning to buy a factory for $100 in
cash (no debt or other financing) in Year 4. Currently the present value of its
Enterprise Value according to the DCF is $200. How would we change the DCF to
account for the factory purchase, and what would our new Enterprise Value be?

Answer 7

In this scenario, you would add CapEx spending of $100 in year 4 of the DCF, which
would reduce Free Cash Flow for that year by $100. The Enterprise Value, in turn,
would fall by the present value of that $100 decrease in Free Cash Flow.

The actual math here is messy but you would calculate the present value by dividing
$100 by ((1 + Discount Rate)^4) – the “4” just represents year 4 here. Then you would
subtract this amount from the Enterprise Value.
