400 Question Flashcards - DCF
What is the basic concept behind a Discounted Cash Flow Analysis?
- The concept is that you value a company based on the present value of its Free Cash Flows far into the future.
- You divide the future into a “near future” period of 5-10 years and then calculate, project, discount, and add up those Free Cash Flows; and then there’s also a “far future” period for everything beyond that, which you can’t estimate as precisely, but which you can approximate using different approaches.
- You need to discount everything back to its present value b/c money today is worth more than money tomorrow.
Walk me through a DCF.
- A DCF values a company based on the present value of its Cash Flows and the present value of its Terminal Value.
- First, you project a company’s financials using assumptions for revenue growth, margins, and the Change in Operating Assets and Liabilities; then you calculate FCF for each year, which you discount and sum up to get to the NPV. The Discount Rate is usually the WACC.
- Once you have the present value of the FCFs, you determine the company’s Terminal Value, using either the Multiples Method or the Gordon Growth Method, and then you discount that back to its NPV using the Discount Rate.
- Finally, you add the two together to determine the company’s Enterprise Value.
Walk me through how you get from Revenue to Free Cash Flow in the projections.
- First, confirm that they are asking for Unlevered FCF (FCF to Firm). If so:
- Subtract COGS and Operating Expenses from Revenue to get to Operating Income (EBIT) - or just use the EBIT margin you’ve assumed.
- Then, multiply by (1 - Tax Rate), add back D&A and other non-cash charges, and factor in the Change in Operating Assets and Liabilities. If Assets increase by more than Liabilities, this is negative; otherwise, it’s positive.
- Finally, subtract CapEx to calculate Unlevered FCF.
- Levered FCF is similar, but you must also subtract the Net Interest Expense before multiplying by the (1 - Tax Rate), and you must also subtract Mandatory Debt Repayments at the end.
What’s the point of Free Cash Flow anyway? What are you trying to do?
- The idea is that you’re replicating the SCF but only including recurring, predictable items. And in the case of Unlevered FCF, you also exclude the impact of Debt entirely.
- That’s why everything in CFI except for CapEx is excluded, and why the entire CFF is excluded (the only exception being Mandatory Debt Repayments for Levered FCF).
Why do use 5 or 10 years for the “near future” DCF projections?
That’s about as far as you can reasonably predict for most companies. Less than 5 years would be too short to be useful, and more than 10 years is too difficult to project for most companies.
Is there a valid reason why we might sometimes project 10 years or more anyway?
You might sometimes do this if it’s a cyclical industry, such as chemicals, b/c it may be important to show the entire cycle from low to high.
What do you usually use for the Discount Rate?
- In an Unlevered DCF analysis, you use WACC, which reflects the “Cost” of Equity, Debt, and Preferred Stock.
- In a Levered DCF analysis, you use Cost of Equity instead.
If I’m working with a public company in a DCF, how do I move from Enterprise Value to Implied per Share Value?
- Once you get to Enterprise Value, ADD Cash and then SUBTRACT Debt, Preferred Stock, and Noncontrolling Interests (and any other debt-like items) to get to Equity Value.
- Then you divide by the company’s share count (factoring in all dilutive securities) to determine the implied per-share price.
Let’s say we do this [move from Enterprise Value to Implied per Share Value for a public company] and find that the Implied per Share Value is $10. The company’s current share price is $5. What does this mean?
- By itself, this does not mean much - you have to look at a range of outputs from a DCF rather than just a single number. So you would see what the Implied per Share Value is under different assumptions for the Discount Rate, revenue growth, margins, and so on.
- If you consistently find that it’s greater than the company’s current share price, then the analysis might tell you that the company is undervalued; it might be overvalued if it’s consistently less than the current share price across all ranges.
An alternative to the DCF is the Dividend Discount Model (DDM). How is it different in the general case (i.e. for a normal company, not a commercial bank or insurance firm?)
- The setup is similar: you still project revenue and expenses over a 5-10 year period, and you still calculate Terminal Value.
- The difference is that you do NOT calculate FCF - instead, you stop at NI and assume that Dividends Issued are a percentage of NI, and then you discount those Dividends back to their present value using the Cost of Equity.
- Then, you add those up and add them to the present value of the Terminal Value, which you might base on a P/E multiple instead.
- Finally, a Dividend Discount Model gets you the company’s Equity Value rather than its Enterprise Value since you’re using metrics that include interest income and expense.
Is it always correct to leave out most of the Cash Flow from Investing section and all of the Cash Flow from Financing section?
- Most of the time, yes, because all items other than CapEx are generally non-recurring, or at least do not recur in a predictable way.
- If you have advance knowledge that a company is going to sell or buy a certain amount of securities, issue a certain amount of stock, or repurchase a certain number of shares every year, then sure, you can factor those in. But it’s extremely rare to do that.
Why do you add back non-cash charges when calculating Free Cash Flow?
For the same reason you add them back on the SCF: you want to reflect the fact that they save the company on taxes, but that the company does not actually pay the expense in cash.
What’s an alternate method for calculating Unlevered Free Cash Flow (Free Cash Flow to Firm)?
There are many “alternate” methods - here are few common ones:
• EBIT * (1 - Tax Rate) + Non-Cash Charges - Changes in Operating Assets & Liabilities - CapEx
• CFO + Tax-Adjusted Net Interest Expense - CapEx
• NI + Tax-Adjusted Net Interest Expense + Non-Cash Charges - Changes in Operating Assets and Liabilities - CapEx
• NOTE: The difference with these is that the tax numbers will be slightly different as a result of when you exclude the interest.
What’s an alternate method to calculate Levered Free Cash Flow?
- NI + Non-Cash Charges - Changes in Operating Assets & Liabilities - CapEx - Mandatory Debt Repayments
- (EBIT - Net Interest Expense) * (1 - Tax Rate) + Non-Cash Charges - Changes in Operating Assets & Liabilities - CapEx - Mandatory Debt Repayments
- CFO - CapEx - Mandatory Debt Repayments
As an approximation, do you think it’s OK to use (EBITDA - Changes in Operating Assets & Liabilities - CapEx) to approximate Unlevered Free Cash Flow?
- This is inaccurate b/c it excludes taxes completely. It would be better to use EBITDA - Taxes - Changes in Operating Assets & Liabilities - CapEx.
- If you need a very quick approximation, yes, this formula can work and it will get you closer than EBITDA by itself. But taxes are significant and should not be overlooked.
What’s the point of that “Changes in Operating Assets and Liabilities” section? What does it mean?
- All it means is that if Assets are increasing by more than Liabilities, the company is spending cash and therefore reducing its cash flow, whereas if Liabilities are increasing by more than Assets, the company is increasing its cash flow.
- For example, if it places a huge order of Inventory, sells products, and records revenue, but hasn’t received the cash from customers yet, Inventory and A/R both go up and represent uses of cash.
- Maybe some of its Liabilities, such as A/P and Deferred Revenue also increase, but think about what happens: if the Assets increase by, say, $100, and the Liabilities only increase by $50, it’s a net cash flow reduction of $50.
- So that is what this section is for - we need to take into account the cash changes from these operationally-linked B/S items.
What happens in the DCF if Free Cash Flow is negative? What if EBIT is negative?
- Nothing “happens” b/c you still run the analysis as-is. The company’s value will certainly decrease if one or both of these turn negative, b/c the present value of FCF will decrease as a result.
- The analysis is not necessarily invalid even if cash flow is negative - if it turns positive after a point, it could still work.
- If the company never turns cash flow-positive, then you may want to skip the DCF b/c it will always produce negative values.
Let’s say that you use Levered Free Cash Flow rather than Unlevered Free Cash Flow in your DCF - what changes?
Levered FCF gives you Equity Value rather than Enterprise Value, since the cash flow is only available to Equity Investors (Debt Investors have already been “paid” with the interest payments and principal repayments).
If you used Levered Free Cash Flow, what should you use as your discount rate?
You would use Cost of Equity rather than WACC since we’re ignoring Debt and Preferred Stock and only care about the Equity Value for Levered FCF.
- Let’s say that you use Unlevered Free Cash Flow in a DCF to calculate Enterprise Value. Then, you work backwards and use the company’s Cash, Debt, and so on to calculate its implied Equity Value.
- Then you run the analysis using Levered Free Cash Flow instead and calculate Equity Value at the end. Will the implied Equity Value from both these analyses be the same?
- No, most likely it will not be the same. In theory, you could pick equivalent assumptions and set up the analysis such that you calculate the same Equity Value at the end.
- In practice, it’s difficult to pick “equivalent” assumptions, so these two methods will rarely, if ever, produce the same value.
- Think about it like this: when you use Unlevered FCF and move from Enterprise Value to Equity value, you’re always using the same numbers for Cash, Debt, etc.
- But in a Levered FCF analysis, the terms of the Debt will impact FCF - so simply by assuming a different interest rate or repayment schedule, you’ll alter the Equity Value. That’s why it’s difficult to make “equivalent assumptions.”
How do you calculate WACC?
- WACC = Cost of Equity * (% Equity) + Cost of Debt * (1 - Tax Rate) * (% Debt) + Cost of Preferred Stock * (% Preferred)
- In all cases, the percentages refer to how much each component comprises of the company’s capital structure.
- For Cost of Equity, you can use CAPM and for the others you usually look at comparable companies and comparable debt issuances and the interest rates and yields issued by similar companies to get estimates.
How do you calculate Cost of Equity?
- Cost of Equity = Risk-Free Rate + Equity Risk Premium * Levered Beta
- The Risk-Free Rate represents how much a 10-year or 20-year US Treasury (or equivalent “safe” government bond in your own country) should yield; Beta is calculated on the “riskiness” of Comparable Companies and the Equity Risk Premium is the percentage by which stocks are expected to out-perform “risk-less” assets like US Treasuries.
- Normally, you pull the Equity Risk Premium from a publication called Ibbotson’s
- NOTE: Depending on your bank and group, you might also add in a “size premium” and “industry premium” to account for additional risk and expected returns from either of those.
- Small-cap stocks are expected to out-perform large-cap stocks and certain industries are expected to out-perform others, and these premiums reflect these expectations.
