Firm Valuation: Value the entire business
Assets
Existing Investments
Generate cashflows today
Includes long lived (fixed) and
short-lived(working
capital) assets
Expected Value that will be
created by future investments
Liabilities
Assets in Place
Debt
Growth Assets
Equity
Fixed Claim on cash flows
Little or No role in management
Fixed Maturity
Tax Deductible
Residual Claim on cash flows
Significant Role in management
Perpetual Lives
Equity valuation: Value just the
equity claim in the business

Discount rate reflects the cost
of raising both debt and equity
financing, in proportion to their
use
Present value is value of the entire firm, and reflects the value of
all claims on the firm.
