INTRODUCTION TO CORPORATE FINANCE
I. What Is Corporate Finance?
Corporate finance addresses three fundamental questions:
Capital Budgeting:
Definition: The process of planning and managing a firm’s long-term investments in assets.
Question: In what long-lived assets should the firm invest?
Example: Should a company open a new plant or develop a new product line?
Capital Structure:
Definition: The mix of debt and equity a firm uses to finance its operations.
Question: How should the firm raise capital to fund investments?
Implication: Affects risk and return for investors. Too much debt increases bankruptcy risk.
Working Capital Management:
Definition: Managing the firm’s short-term assets and liabilities.
Question: How should the firm manage its everyday financial activities (cash, inventory, receivables, payables)?
Goal: Ensure liquidity while maximizing efficiency.
II. The Balance Sheet Model of the Firm
Visual Framework (Figure 1.1):
Left Side = Firm’s Assets
Right Side = Financing Sources (Debt + Equity)
Assets:
Current Assets: Cash, inventory, receivables.
Fixed Assets: Tangible (buildings, machines) & Intangible (patents, trademarks).
Liabilities:
Current Liabilities: Short-term debts, accounts payable.
Long-Term Debt: Bonds, loans beyond one year.
Equity: Residual interest of shareholders (assets – liabilities).
Net Working Capital (NWC) = Current Assets – Current Liabilities
A key metric in understanding short-term liquidity.
III. The Financial Manager’s Role
The financial manager is tasked with answering the three fundamental questions of corporate finance.
Organizational Roles (Figure 1.2):
CFO (Chief Financial Officer):
Oversees both:
Treasurer – Handles capital expenditures, cash management, financial planning.
Controller – Handles financial reporting, accounting, taxes, and information systems.
Financial management is about decision-making aimed at increasing firm value.
IV. Business Organization Types
Type | Pros | Cons |
Sole Proprietorship | Easy to form, full control, single taxation | Unlimited liability, limited life, difficult to raise capital |
Partnership | Shared workload/resources, tax benefits | Unlimited liability (general partners), limited life |
Corporation | Limited liability, easier capital access, perpetual life | Double taxation, regulatory requirements |
LLC | Limited liability + partnership tax benefits | Varies by state, can be treated as corporation by IRS |
Note: Most large firms opt for the corporate form due to scalability, transferability of shares, and access to capital markets.
V. Cash Flow Is King
Corporate finance focuses on cash flows, not accounting profits.
Cash Flow vs. Accounting Income:
GAAP may report profits when no cash is received (Example: Midland Company sells gold but hasn’t collected payment).
Finance focuses on actual cash received and spent.
Key Concepts:
Value Creation = Buy assets that generate more cash than they cost.
Cash Flow Identification = Not always straightforward—requires interpretation of financial statements.
Timing Matters:
Time Value of Money: $1 today > $1 tomorrow.
Early cash flows are more valuable (Example: Product B vs. Product A).
Risk Considerations:
Cash flows are uncertain, and investors are generally risk-averse.
Risk-adjusted decisions must weigh potential loss against potential gain (Example: Europe vs. Japan expansion).
VI. The Goal of Financial Management
Common (but flawed) goals:
Maximize sales, minimize costs, beat competitors, avoid bankruptcy.
Problems:
Not necessarily aligned with owner/shareholder interests.
May ignore timing, risk, and sustainability.
Correct Objective:
Maximize the current value per share of the existing stock.
This goal:
Reflects ownership interests.
Accounts for timing and risk of cash flows.
Avoids the short-run vs. long-run dilemma.
Applies to any ownership structure by rephrasing as:
➤ Maximize the value of owners’ equity.
VII. The Agency Problem
What is it?
An agency relationship arises when one party (agent) is expected to act on behalf of another (principal).
Agency Problems:
Misaligned incentives between managers (agents) and shareholders (principals).
Examples:
Avoiding risky but value-enhancing investments.
Spending on unnecessary luxuries (private jets).
Pursuing personal prestige or job security over firm value.
Agency Costs:
Direct:
Expenditures benefitting managers (e.g., luxury offices)
Monitoring expenses (e.g., audits)
Indirect:
Missed opportunities due to risk aversion or misalignment.
VIII. Managing Agency Conflicts
Compensation Tied to Performance:
Stock options, restricted stock, performance bonuses.
Aligns manager incentives with shareholder value.
Market for Corporate Control:
Poor management → risk of takeover or proxy fight.
Proxy fight: Shareholders attempt to replace the board.
Example: Darden Restaurants vs. Starboard Value.
Job Market Reputations:
Strong performance → better jobs and pay elsewhere.
Board Oversight:
Independent directors enhance governance.
IX. Stakeholders and Governance
Stakeholders = All parties with interest in firm’s operations:
Employees, suppliers, customers, regulators, community.
While the goal is to maximize shareholder wealth, ignoring stakeholders can harm long-term value (e.g., brand damage, legal risks).
X. Regulation & Ethics in Finance
Federal Laws:
Securities Act of 1933 – Requires disclosure at time of issuing new securities.
Securities Exchange Act of 1934 – Ongoing regulation (insider trading, financial reporting).
Requires annual (10-K), quarterly (10-Q), and major event (8-K) reports to the SEC.
Insider Trading:
Illegal to trade on non-public, material information (e.g., upcoming mergers or earnings).
Sarbanes-Oxley Act (Sarbox, 2002):
Passed after scandals (Enron, WorldCom).
Requirements:
CEO/CFO personally certify financial statements.
Annual assessments of internal controls (Section 404).
Creation of PCAOB (audit regulator).
Independent audit committees.
Costs: Expensive compliance → fewer IPOs, firms "go dark".

FINANCIAL STATEMENTS AND CASH FLOW
I. Purpose of the Chapter
Understanding that cash flow, not net income or book value, is central to corporate finance. Financial statements offer different perspectives, but financial managers focus on the firm’s ability to generate cash.
II. The Balance Sheet
Definition: A snapshot of the firm's financial position at a point in time.
Equation:
Assets = Liabilities + Shareholders’ Equity
A. Key Concepts in Balance Sheet Analysis
Liquidity:
Definition: How easily an asset can be converted to cash without significant loss.
Hierarchy:
Cash > Receivables > Inventory > Fixed Assets
Trade-off: Liquidity vs. Return
Liquid assets are safer but typically generate lower returns.
Debt vs. Equity:
Debt = Fixed obligation (interest + principal)
Failure to pay leads to default.
Equity = Residual claim
Only paid after debt obligations are met.
Implication: Too much debt increases financial risk.
Book Value vs. Market Value:
Book Value: Based on historical cost (GAAP).
Market Value: Current price someone is willing to pay.
Finance focuses on market value when evaluating investment decisions.
III. The Income Statement
Definition: Measures financial performance over a period.
Equation:
Revenues − Expenses = Net Income
Key Metrics:
EBIT (Earnings Before Interest and Taxes):
Focuses on operating performance.
Net Income: “Bottom line” after interest and taxes.
EPS: Net Income / Shares Outstanding
A. Important Considerations
GAAP & Matching Principle:
Revenues and expenses are recorded when earned/incurred—not when cash changes hands.
Non-Cash Items:
Depreciation: Allocated cost of fixed assets.
Deferred Taxes: Taxes owed in the future due to timing differences between accounting and tax rules.
Time and Cost Classifications:
Fixed Costs: Do not vary with output (e.g., rent).
Variable Costs: Change with production (e.g., raw materials).
Product Costs: Tied to production; included in COGS.
Period Costs: Not directly tied to production; expensed when incurred (e.g., SG&A).
IV. Corporate Taxes
Tax Rate Structure (2015):
Nonlinear; includes “tax bubbles” where marginal rates temporarily increase and then fall.
Key Rates:
Marginal Tax Rate: Tax on the next dollar earned (used for decision-making).
Average Tax Rate: Total tax paid / Total taxable income.
Example Calculation:
Taxable Income = $200,000
Total Tax = $61,250
Avg Tax Rate = 30.625%
Marginal Tax Rate = 39%
Reality: Effective tax rates differ widely by industry (e.g., biotech: ~4.5%, utilities: ~34%).
V. Net Working Capital (NWC)
NWC = Current Assets – Current Liabilities
Indicator of short-term financial health.
A positive NWC suggests more cash will be received than paid in the near term.
Change in NWC reflects short-term investment activity.
VI. Financial Cash Flow
A. Cash Flow from Assets (CFA)
CFA = OCF − Capital Spending − ∆NWC
1. Operating Cash Flow (OCF)
OCF = EBIT + Depreciation − Taxes
Captures cash generated from core operations.
2. Capital Spending
Capital Spending = Net Fixed Assets (end) − Net Fixed Assets (beg) + Depreciation
3. Change in Net Working Capital (∆NWC)
∆NWC = NWC (end) − NWC (beg)
B. Cash Flows to Stakeholders
Cash Flow to Creditors:
= Interest Paid − Net New Borrowing
Example:
Interest = $49M, Debt Increased by $13M
→ Cash to Creditors = $49 − $13 = $36M
Cash Flow to Stockholders:
= Dividends − Net New Equity Issued
Example:
Dividends = $43M, Net Equity = $43 − $6 (repurchase) = $37M
→ Cash to Stockholders = $43 − $37 = $6M
VII. Total vs. Operating Cash Flow
Total Cash Flow of the Firm = Cash from operations available to creditors and stockholders.
Sometimes referred to as Free Cash Flow.
A negative total cash flow is not inherently bad—may indicate high investment/growth.
VIII. Statement of Cash Flows (Accounting Format)
Divided into 3 sections:
Operating Activities:
Net Income
Depreciation
Deferred Taxes
+/− Changes in Working Capital Items (e.g., receivables, payables, inventory)
Investing Activities:
Purchases and sales of fixed assets.
Financing Activities:
Debt issuance/retirement
Equity issuance/repurchase
Dividends paid
IX. Differences Between Accounting and Financial Cash Flow
Topic | Accounting View | Financial View |
Interest Expense | Operating Activity | Financing Activity |
Focus | Accrual Basis (GAAP) | Cash Movement |
Target Metric | Net Income | Cash Flow from Assets |
Non-Cash Items | Included (e.g., Depreciation) | Adjusted for |
X. Real-World Accounting Manipulation Examples
Tyco: Classified purchases as financing to inflate operating cash flow.
Dynegy: Round-trip trades falsely boosted operating cash flow.
Adelphia: Overcapitalized labor to understate operating costs.
Lesson: Firms can manipulate operating cash flow, but total cash flow from assets is harder to spin.
XI. Summary
Finance focuses on cash flow—not net income.
Cash flow from assets = Cash available to creditors and shareholders.
OCF, Capital Spending, and ∆NWC are the key components.
Accounting income ≠ cash flow due to timing, non-cash items, and accruals.
Tax rate differences matter—marginal rate is more relevant than average.
Accounting statement of cash flows is a helpful but limited summary.
🧾 I. Purpose of Financial Statement Analysis
Goal: To use financial statements to assess a company’s financial health, performance, and position.
Why it matters: Financial statements are the primary way financial information is communicated.
Key insight: Raw financial statements are hard to compare across companies—standardization and ratio analysis help interpret them effectively.
📊 II. Standardizing Financial Statements
1. Common-Size Balance Sheet
Express each item as a % of total assets.
Helps compare companies of different sizes or over time.
Example: If cash = $84 and total assets = $3,373, then cash = 2.5% of total assets.
2. Common-Size Income Statement
Each line is shown as a % of total sales.
Useful for cost control and margin comparison.
Example: If COGS = $1,344 and sales = $2,311, then COGS = 58.2% of sales.
📐 III. Financial Ratios
Grouped into five categories:
I. Short-Term Solvency (Liquidity) Ratios
These measure a firm’s ability to meet short-term obligations. Essential for banks and short-term creditors.
Ratio | What It Does | Why It’s Important | Unit |
Current Ratio = Current Assets / Current Liabilities | Measures how well a company can pay off its short-term debts using its short-term assets. | A ratio >1 means more assets than liabilities (generally good). Too high might suggest inefficiency. Too low indicates liquidity risk. | Times (x) |
Quick Ratio (Acid-Test) = (Current Assets – Inventory) / Current Liabilities | Measures liquidity, excluding inventory (which might be hard to convert to cash quickly). | More conservative than the current ratio. Important in industries with slow-moving or obsolete inventory. | Times (x) |
Cash Ratio = Cash / Current Liabilities | Looks only at actual cash available to pay short-term debt. | Most conservative liquidity ratio; useful for crisis situations or highly liquid firms. | Times (x) |
II. Long-Term Solvency (Leverage) Ratios
Assess a firm’s long-term debt capacity and financial structure. Important for investors, rating agencies, and long-term lenders.
Ratio | What It Does | Why It’s Important | Unit |
Total Debt Ratio = (Total Assets – Total Equity) / Total Assets | Shows what % of assets are financed by debt. | The higher the ratio, the more the firm relies on debt. Moderate debt can boost returns, but high debt increases risk. | Decimal or % |
Debt-to-Equity Ratio = Total Debt / Total Equity | Compares debt to shareholder equity. | Indicates leverage. High ratio suggests aggressive financing, which may boost ROE but increases risk. | Times (x) |
Equity Multiplier = Total Assets / Total Equity | Measures the degree of financial leverage. | Higher multiplier means more debt relative to equity. Key component of DuPont Identity (ROE). | Times (x) |
Times Interest Earned (TIE) = EBIT / Interest Expense | Measures how many times the company can pay its interest with operating income. | Shows how comfortably a firm can service its debt. Lower values (<2) are risky. | Times (x) |
Cash Coverage Ratio = (EBIT + Depreciation) / Interest | Accounts for non-cash expenses; shows cash-based ability to pay interest. | Preferred over TIE because it reflects real cash available. | Times (x) |
III. Asset Management (Turnover) Ratios
Measure how efficiently the firm uses its assets to generate sales.
Ratio | What It Does | Why It’s Important | Unit |
Inventory Turnover = COGS / Inventory | Shows how many times a company "sells and replaces" its inventory in a year. | High = efficient inventory use. Low = overstock or slow sales. | Times (x) |
Days Sales in Inventory = 365 / Inventory Turnover | Converts inventory turnover into days. | Tells how long inventory is held before sale. Shorter is usually better. | Days |
Receivables Turnover = Sales / Accounts Receivable | How often accounts receivable are collected in a year. | High = fast collection (good cash flow). Low = slow collection (credit risk). | Times (x) |
Days Sales in Receivables (Average Collection Period) = 365 / Receivables Turnover | Converts turnover into days. | Tells how many days it takes to collect on credit sales. | Days |
Total Asset Turnover = Sales / Total Assets | Measures how efficiently all assets are used to generate revenue. | Higher = better asset use. Industry-dependent (retail is high, utilities are low). | Times (x) |
IV. Profitability Ratios
These show how efficiently a company turns revenue into profit. Highly watched by investors and management.
Ratio | What It Does | Why It’s Important | Unit |
Profit Margin = Net Income / Sales | % of each dollar of sales that turns into profit. | Reflects pricing strategy and cost control. Thin margins = high competition. | % |
Return on Assets (ROA) = Net Income / Total Assets | Profit earned per dollar of assets. | Measures management effectiveness using all resources. Higher is better. | % |
Return on Equity (ROE) = Net Income / Equity | Profit earned per dollar of shareholder equity. | Shows how well the firm rewards its shareholders. Boosted by leverage. | % |
EBITDA Margin = EBITDA / Sales | Shows core cash profitability from operations. | Ignores interest, tax, and depreciation—useful for comparing operating strength. | % |
V. Market Value Ratios
Useful for publicly traded companies. These involve stock price and reflect investor sentiment, growth potential, and valuation.
Ratio | What It Does | Why It’s Important | Unit |
Earnings Per Share (EPS) = Net Income / Shares Outstanding | Net income per share of stock. | Core indicator of profitability per unit of ownership. | Dollars ($) |
Price-to-Earnings (P/E) Ratio = Price per Share / EPS | How much investors pay for $1 of earnings. | High P/E = growth expected. Low P/E = undervalued or weak prospects. | Times (x) |
Market-to-Book Ratio = Market Price / Book Value per Share | Compares market value of equity to its accounting value. | >1 = firm creating value. <1 = destroying value (red flag). | Times (x) |
Enterprise Value (EV) = Market Cap + Debt – Cash | Theoretical purchase price of a company. | Important for mergers and acquisition decisions. | Dollars ($) |
EV / EBITDA Multiple = EV / EBITDA | Standard valuation multiple that strips out capital structure and taxes. | Useful for comparing companies with different debt/tax structures. | Times (x) |
Bonus: 📐 Capital Intensity Ratio
Formula: Total Assets / Sales
What It Means: Amount of assets needed to generate $1 in sales.
Why Important: High = capital intensive (e.g., manufacturing). Low = asset light (e.g., software).
Unit: Dollars ($)
🧩 IV. DuPont Identity (Decomposition of ROE)
Breaks ROE into three components:
ROE = Profit Margin × Total Asset Turnover × Equity Multiplier
This shows how:
Efficiency (PM)
Asset usage (TAT)
Financial leverage (EM)
… all combine to influence returns to equity holders.
⚠ V. Problems with Ratio Analysis
No Theory: Hard to determine "good" vs. "bad" ratios.
Different Accounting Methods: e.g., LIFO vs FIFO.
Timing Differences: Fiscal years vary.
Conglomerates: Mix of business lines distorts comparisons.
Global Firms: Different standards (GAAP vs IFRS).
Seasonality: E.g., retail businesses around holidays.
📈 VI. Financial Planning Models
A. Pro Forma Statements
Project future income statements and balance sheets.
Used for budgeting, forecasting, and strategic planning.
B. Percentage of Sales Method
Assumes certain balance sheet and income items grow with sales.
Items are classified as:
Varying directly with sales (e.g., inventory)
Not varying (e.g., long-term debt)
C. External Financing Needed (EFN)
When projected assets > liabilities + equity, EFN is the gap.
Shows whether more funds must be raised.
Formula:
EFN = Increase in assets – (Increase in spontaneous liabilities + Retained earnings)
🔁 Summary Tips for Studying:
Memorize the five categories of ratios and examples in each.
Practice calculating ratios using real or hypothetical data.
Understand relationships: e.g., how increased debt raises ROE via DuPont.
Be aware of limitations in ratio comparisons.
Work through pro forma scenarios to understand financial planning.
💡 1. Time Value of Money (TVM)
A dollar today is worth more than a dollar tomorrow
Why?
You can invest it and earn a return
Inflation decreases value over time
There's risk in future payments
The concept that money available now is worth more than the same amount in the future due to its earning potential.
💰 2. Future Value (FV)
Formula:
FV = C₀ × (1 + r)^T
Where:
C₀ = initial cash invested today
r = interest rate per period
T = number of periods
The amount an investment is worth after one or more periods of growth at a specified interest rate.
💵 3. Present Value (PV)
Formula:
PV = C_T / (1 + r)^T
Where:
C_T = future cash flow at time T
r = discount rate per period
T = number of periods into the future
The current value of a future amount of money, discounted back to today using a specific interest rate.
✅ 4. Net Present Value (NPV)
Formula:
NPV = -C₀ + Σ [ C_t / (1 + r)^t ]
Where:
C₀ = cost/investment today
C_t = cash flows over time
r = discount rate
t = time index
The difference between the present value of future cash inflows and the initial investment. It measures the profitability of a project.
📉 5. Discounting & Compounding
Compounding:
FV = C₀ × (1 + r)^T
The process of earning interest on both the initial principal and the accumulated interest from previous periods.
Discounting:
PV = C_T / (1 + r)^T
The interest rate used to calculate present value. It reflects the opportunity cost of capital or required return on investment.
🧠 6. Rule of 72 (Estimate doubling time)
Years to double ≈ 72 / Interest rate
Example: At 9%, doubling ≈ 8 years
A shortcut formula to estimate the time it takes for money to double at a given interest rate:
📆 7. Present Value of Multiple Cash Flows
Discount each cash flow separately and sum:
PV = C₁ / (1 + r)^1 + C₂ / (1 + r)^2 + ... + C_T / (1 + r)^T
🏦 8. Annuity (Level Payments for a Fixed Time)
A series of equal payments made at regular intervals for a fixed period of time.
Present Value of Annuity:
PV = C × [1 - (1 / (1 + r)^T)] / r
Future Value of Annuity:
FV = C × [(1 + r)^T - 1] / r
♾ 9. Perpetuity (Level Payments Forever)
A stream of equal payments that continues forever.
Present Value of Perpetuity:
PV = C / r
📈 10. Growing Perpetuity
A stream of cash flows that grows at a constant rate and continues forever.
Present Value of Growing Perpetuity:
PV = C / (r - g)
Where:
C = cash flow one year from now
r = discount rate
g = growth rate
(must have r > g)
⏳ 11. Solving for Time or Interest Rate
Solving for Rate (r):
r = (FV / PV)^(1/T) - 1
Solving for Time (T):
T = log(FV / PV) / log(1 + r)
🔢 12. APR vs. EAR
APR - The nominal yearly interest rate that does not account for compounding within the year.
EAR (Effective Annual Rate):
EAR = (1 + r/m)^m - 1
Where:
r = annual percentage rate (APR)
m = number of compounding periods per year
The actual annual interest rate earned or paid after accounting for compounding.
📈 13. Continuous Compounding
A theoretical concept where interest is compounded an infinite number of times per year.
Future Value with Continuous Compounding:
FV = C₀ × e^(r × T)
A factor used to calculate the future value of an annuity:
Present Value with Continuous Compounding:
PV = C_T / e^(r × T)
Where e ≈ 2.718
A factor used to calculate the present value of an annuity:
🧾 14. Excel / Spreadsheet Formulas
Goal | Formula |
Future Value | =FV(rate, nper, pmt, pv) |
Present Value | =PV(rate, nper, pmt, fv) |
Interest Rate | =RATE(nper, pmt, pv, fv) |
Number of Periods | =NPER(rate, pmt, pv, fv) |
Use decimals for rate (e.g. 8% → 0.08)
Input outflows (like pv) as negative numbers
📊 15. Example: Colin Kaepernick’s Contract
Total quoted = $121 million
PV = ~$84 million
Why? Payments spread over years and discounted using TVM
