E(R) = Rf + B (Rm- Rf)
Cost of Equity = E(Ri) = Rf + Equity Beta * (E(Rm) - Rf)
Cost of equity = Risk-free rate + Beta * (U.S. risk premium) + Country risk premium
Cost of equity = Risk-free rate + Beta * (U.S. risk premium + Default spread)
Relative standard deviation country x = Standard deviation country x / Standard deviation U.S.
Equity risk premium country x = Risk premium U.S. * Relative standard deviation country x
Country risk premium = Country default spread * ( Std. Dev. equity / Std. Dev. country bond)
E(Return)=Riskfree Rate+ Вeta (US premium) + λ (Country risk premium)
λ =% of revenues domesticallyfirm / % of revenues domesticallyavg firm

Interest Coverage Ratio = EBIT / Interest Expenses

MV of debt = Int. Exp. (1/r – 1 / r(1+r) n) + BV of debt / (1+r) n

Straight bond component = Market value of bond
Conversion option = Book value of bond at issuance – Straight bond component
Cost of PS = Preferred dividend per share / Market price per preferred share
CASH FLOW DEFINITIONS
EBIT (1 – tax rate)
- (Capital Expenditures – Depreciation)
- Change in non-cash working capital
= Free Cash Flow to Firm (FCFF)
Net Income
- (Capital Expenditures – Depreciation)
- Change in non-cash Working Capital
- (Principal Repaid – New Debt Issued)
- Preferred Dividend
+ Dividends and Stock Buybacks
= Free Cash Flow to Equity
Revenues
(-) Operating Expenses
= Operating Income
(-) Financial Expenses
(-) Taxes
= Net Income before Extraordinary Items
(-) or (+) Extraordinary Losses (Profits)
R&D, OPERATING LEASE ADJUSTMENTS
Adjusted operating income = Operating income + Current year’s R&D expense – Amortization
of research asset
Adjusted net income = Net income + Current year’s R&D expense – Amortization of research
asset
Debt Value of Operating Leases = PV of Operating Lease Expenses at the pre-tax cost of debt
Adjusted debt = Debt + Present value of lease commitments
Adjusted Operating Earnings = Operating Earnings + Operating Lease Expenses - Depreciation
on Leased Asset
Adjusted Net Capital Expenditures = Net Capital Expenditures + Current year’s R&D expenses Amortization of Research Asset
Adjusted Net Cap Ex = Net Capital Expenditures + Acquisitions of other firms - Amortization of
such acquisitions
GROWTH ESTIMATION – DIFFERENT MODELS
Net Income
- (1- δ) (Capital Expenditures - Depreciation)
- (1- δ) Working Capital Needs
= Free Cash flow to Equity
δ = Debt/Capital Ratio
Reinvestment Rate = Retained Earnings/ Current Earnings = Retention Ratio
Return on Investment = ROE = Net Income/Book Value of Equity
gEPS
= Retained Earningst-1/ NIt-1 * ROE
= Retention Ratio * ROE
= b * ROE
gEPS= b *ROEt+1 +(ROEt+1– ROEt) ROEt
gEPS= b *ROEt+1 + (ROEt+1– ROEt)(BV of Equityt )/ ROEt (BV of Equityt)
ROE = ROC + D/E (ROC - i (1-t))
BV of capital = BV of Debt + BV of Equity
Reinvestment Rate = (Net Capital Expenditures + Change in WC)/EBIT(1-t)
Return on Investment = ROC = EBIT(1-t)/(BV of Debt + BV of Equity)
gEBIT
= (Net Capital Expenditures + Change in WC)/EBIT(1-t) * ROC
Expected Growth Rate = ROCt+1 * Reinvestment rate
+(ROCt+1 – ROCt)/ROCt
Value = Expected Cash Flow Next Period / (r - g)
Stable Growth Payout Ratio = 1 - g/ ROE
Reinvestment Rate = Growth in Operating Income/ROC
Value of Bond = PV of coupons at market interest rate + PV of face value of bond at market
interest rate
