Overview of Corporate Finance
-
What is Finance about? Finance is about Decision Making
You are an investor. Should you invest in Microsoft stock at its current price of $41/share?
You are a manager at Toyota. Should a vehicle part be manufactured in-house or outsourced?
You are the CEO of The GAP. Should you open new stores, or close existing ones? Should you buy or lease the properties?
You are the CFO of Apple. What should Apple do with its $150 billion in cash: pay out dividends, repurchase shares, acquire companies, or just hoard it?
You are on the Board of Google. Should Google become a wireless service provider?
-
What is Finance about? In making these decisions
What is your objective? What information do you need?
Strategic Goals and Objectives
Financial Tools and Analysis
Corporate Decisions
-
Good decisions Every decision has future consequences
Costs Benefits
What is a good decision?
Value of Benefits > Value of Costs
Decision making follows from valuation The net benefit of a decision is referred to as its Net Present Value:
NPV = Value of Benefits - Value of Costs = Contribution to Shareholder Value
Good decisions have positive NPV How can we determine NPV?
Depends on investor preferences/financial markets
-
Financial Markets and Investor Preferences
Example 1: Ford shareholders meeting, three very different shareholders
Impatient type: retiree, wants short-term profit Ford should invest more in current best selling line
Patient type: childs trust fund representative, wants money a long way in the future Ford should invest in fuel cell technology for electric cars
Intermediate type: pension fund representative believes an oil crisis is likely in near future wants Ford to build small cars
How can the interests of all 3 shareholders be reconciled?
-
Financial Markets and Investor Preferences
Example 2: Four entrepreneurs, with $100K each
Bob: wine lover. Can buy a small vineyard for $100K, which will be worth $400K in five years but his daughter just got into Princeton, needs money now
Alice: loves food, wants to open a restaurant. For $100K now, gets $300K in five years needs money in 5 years, when her son goes to college
Bill and Greg: want to co-invest to run an ice-cream company. For $100K now, each gets $150K in five years need money in five years when they retire
Should they do these projects?

Bill and Greg: want to co-invest to run an ice-cream company. For $100K now, each gets $150K in five years need money in five years when they retire
There are two fiercely competitive banks in town, that will take deposits and make loans at close to 15% per year (so that $100K now is worth about $200K in five years)

Example 2: Four entrepreneurs, with $100K each
Bob: wine lover. Can buy a small vineyard for $100K, which will be worth $400K in five years but his daughter just got into Princeton, needs money now NPV > 0: invest $100, borrow $200 against the project
Alice: loves food, wants to open a restaurant. For $100K now, gets $300K in five years needs money in 5 years, when her son goes to college NPV > 0, invest!
Bill and Greg: want to co-invest to run an ice-cream company. For $100K now, each gets $150K in five years NPV < 0, put money in the bank instead (so Bob can invest)
This is called frictionless financial markets
-
Financial Markets and Investor Preferences Example 2: with frictionless markets, decisions which
projects to take do not depend on investor preferences
Take projects with NPV > 0! Example 1, ford shareholders: with frictionless markets,
unanimously agree to take projects with NPV > 0, even though they have different preferences:
What should impatient shareholders do if Ford invests in
long-term projects with NPV > 0?
-
Frictionless markets and Frictions
In frictionless markets investors agree to take projects with NPV > 0
Frictionless (perfect) markets: no frictions
Private information Agency frictions Bankruptcy costs Taxes Transaction costs Mispriced securities

-
Unanimity and Separation of Ownership and Control
Shareholders agree that managers should maximize NPV set incentives so that managers follow the NPV rule do not to intervene to day-to-day running of the firm can diversify their wealth across many different
companies (would be impossible if shareholders needed to run companies day-to-day)
-
Valuation Determining value (NPV): need to get information about
market preferences/beliefs (well do this a lot in class) - Interest rates - Measures of Risk (volatility, Beta) - Expected growth
We will also get a lot of info from Financial Statements - Cash flows we start talking about them on Thursday
What happens when market/prices are wrong?

Well talk more later about how to compute Ct and r Use financial statements Use market prices, interest rates
For now, just take them as given
Calculating Ct and r
-
Shortcuts allow us to cut through the calculations quickly
Annuity: an asset that pays a fixed sum each year for a specified number of years Ex: Mortgage loans
Perpetuity: an asset that pays a fixed sum forever Ex: Preferred stock. Stockholder promised a fixed
cash dividend every quarter, forever.

Perpetuity
PV = C(1+r) + C(1+r)2 + C(1+r)3 ... (1)multiply by 1+r
Subtracting (1) from (2), we have r PV = C. Therefore,
(1+ r)PV = C + C(1+r ) + C(1+r )2 ... (2)

1. Getting all annuity/perpetuity formulas from this one 2. Assumptions about r and g 3. The timing of cash flows

What is the monthly payment on a 30-year mortgage of $100,000 with 4.2% APR?
Example: Mortgage
-
Consider a company in stable growth. Assume that company earnings grow at the real GDP growth rate of 2.5% and it pays out a fixed fraction of earnings as dividends. Assume the real discount rate of 7.5%.
What percentage of company value comes from cash flow in years 1 through 5? What percentage comes from cash flows after year 5? After year 10?
Useful website with GDP data: www.bea.gov
Example: Terminal Value
-
Consider a company that reinvests 2/3 of its earnings in years 1-10, and grows at the real rate of 10%. Starting in year 11, it reaches stable growth, reinvests 1/3 of earnings and grows at the rate of 2.5%. The real discount rate is 7.5%. Assuming that the company pays out earnings that it does not reinvest, what percentage of its value is in terminal value (after year 10)?
Terminal Value, Growth Company
-
If the terminal value contains a huge percentage of company value(especially for growth companies), then a good estimate of growth is crucial to valuation. How easy is it to estimate?

Persistence of Growth
-
Ann is now 25 years old and she is planning to start saving for retirement. She expects her income of $60,000 in the coming year to grow at the (nominal) rate of 5% a year until she retires at the age of 65. She wants to save a fixed percentage of her income per year. She wants to save enough money to be able to consume per year 50% of her income (in real terms) just before retirement (at age 65) for 20 years. Assume the inflation rate of 3%, and a nominal rate of return on Anns savings of 6%. What fraction of income should Ann be saving?
Note: Survey of Consumer Finances has lots of useful info, at www.federalreserve.gov/pubs/oss/oss2/scfindex.html
Example: Saving for Retirement
-
rate of inflation i real rate of return rR then the nominal rate of return can be found
from 1 + rN = (1 + i) (1 + rR)
Approximately, rN = i + rR.
Note 1: Real vs. Nominal Rates
-
Note 2: Continuously Compounded vs. Yearly Rates
r is annual rate rc is continuously compounded rate
exp(rc) = 1 + r r = exp(rc) 1 rc = ln(1 + r)

Should You Pay Cash?
Read the LA Times article, Should You Pay Cash for a New Car? What is the monthly payment Keppel will need to make
on his car loan? What is the Total Interest Paid on the loan? How much interest will he earn on his savings? What is Sperlings Rule? What is the right decision?
Why?

Mellon Banks Cornerstone Gold Card Read the brochure describing Mellon Banks Cornerstone
Gold Card Suppose you
keep the card for 20 years maintain a $5000 monthly balance dont pay the balance in full each month (so that you do incur
interest charges) Consider:
With a 14.9% APR, what are your cash flows? Can Mellon Bank claim that the card charges a 0% effective rate Is the IRR a useful way to evaluate this card? What effective
interest rate would you associate with the card? Under what circumstances is this card a good deal? Can you see any potential problems for Mellon Bank associated
with this card?
