Introductory Corporate Finance: Financial Statement Analysis - Income Statement, Revenue COGS Operating Expenses EBIT Net Income Non-Cash Charges Depreciation Amortization

What This Is

The income statement is a financial statement that summarizes a company's revenues and expenses over a specific period. It's a crucial tool for investors, analysts, and corporate finance professionals to evaluate a company's profitability and performance. Let's consider an example: Tesla, Inc. (TSLA) reported revenue of $53.8 billion, cost of goods sold (COGS) of $24.6 billion, and operating expenses of $7.3 billion in 2022. By analyzing the income statement, we can calculate the company's earnings before interest and taxes (EBIT), net income, and other key metrics.

Key Formulas & Models

• Revenue = Sales × (1 - Returns) × (1 - Discounts) – total revenue; measures sales, returns, and discounts.
  • Sales: total sales revenue
  • Returns: percentage of sales returned by customers
  • Discounts: percentage of sales discounted by the company
• COGS = Beginning Inventory + Purchases - Ending Inventory – cost of goods sold; measures production costs.
  • Beginning Inventory: inventory at the start of the period
  • Purchases: total purchases of raw materials and goods
  • Ending Inventory: inventory at the end of the period
• Operating Expenses = Salaries + Rent + Utilities + Depreciation + Amortization – operating expenses; measures non-production costs.
  • Salaries: total employee salaries and benefits
  • Rent: total rent and lease payments
  • Utilities: total utility bills (electricity, water, gas, etc.)
  • Depreciation: non-cash expense for asset depreciation
  • Amortization: non-cash expense for intangible asset amortization
• EBIT = Revenue - COGS - Operating Expenses – earnings before interest and taxes; measures profitability before financing costs.
• EBITDA = EBIT + Depreciation + Amortization – earnings before interest, taxes, depreciation, and amortization; measures cash flow from operations.
• Net Income = EBIT - Interest - Taxes – net income; measures profitability after financing costs and taxes.
• Non-Cash Charges = Depreciation + Amortization – non-cash expenses; measures asset depreciation and intangible asset amortization.
• ROCE = EBIT / (Total Assets - Current Liabilities) – return on capital employed; measures profitability relative to capital employed.
• ROE = Net Income / Total Shareholders' Equity – return on equity; measures profitability relative to shareholders' equity.

Step-by-Step Calculation

1. Calculate COGS using the formula: COGS = Beginning Inventory + Purchases - Ending Inventory.
2. Calculate Operating Expenses by adding Salaries, Rent, Utilities, Depreciation, and Amortization.
3. Calculate EBIT by subtracting COGS and Operating Expenses from Revenue.
4. Calculate EBITDA by adding Depreciation and Amortization to EBIT.
5. Calculate Net Income by subtracting Interest and Taxes from EBIT.
6. Calculate Non-Cash Charges by adding Depreciation and Amortization.

Common Mistakes

1. Mistake: Ignoring Depreciation and Amortization when calculating EBITDA.
   • Correction: Include Depreciation and Amortization to accurately measure cash flow from operations.
   • Counterexample: A company reports EBIT of $10M, but ignores Depreciation of $5M, resulting in an incorrect EBITDA of $15M.
2. Mistake: Confusing COGS with Operating Expenses.
   • Correction: COGS measures production costs, while Operating Expenses measure non-production costs.
   • Counterexample: A company reports COGS of $20M, but incorrectly labels it as Operating Expenses, resulting in an incorrect EBIT of $30M.
3. Mistake: Failing to consider Non-Cash Charges when calculating Net Income.
   • Correction: Include Depreciation and Amortization to accurately measure Net Income.
   • Counterexample: A company reports EBIT of $10M, but ignores Depreciation of $5M, resulting in an incorrect Net Income of $15M.

Exam / CFA Tips

1. Tip: Be careful when using the M&M Proposition I (no taxes) formula, as it assumes a constant cost of capital.
2. Tip: When calculating ROE, use the correct formula: ROE = Net Income / Total Shareholders' Equity.
3. Tip: Be aware of the difference between IRR and NPV ranking, as they are used in different contexts.

Quick Practice Problem

A company has EBIT of $10M, interest of $2M, and taxes of 25%. Calculate the company's Net Income.

Answer: Net Income = $10M - $2M - ($10M x 0.25) = $7.5M

Explanation: Calculate Net Income by subtracting Interest and Taxes from EBIT.

Last-Minute Cram Sheet

1. Revenue = Sales × (1 - Returns) × (1 - Discounts) – measures sales, returns, and discounts.
2. COGS = Beginning Inventory + Purchases - Ending Inventory – measures production costs.
3. Operating Expenses = Salaries + Rent + Utilities + Depreciation + Amortization – measures non-production costs.
4. EBIT = Revenue - COGS - Operating Expenses – measures profitability before financing costs.
5. EBITDA = EBIT + Depreciation + Amortization – measures cash flow from operations.
6. Net Income = EBIT - Interest - Taxes – measures profitability after financing costs and taxes.
7. Non-Cash Charges = Depreciation + Amortization – measures asset depreciation and intangible asset amortization.
8. ROCE = EBIT / (Total Assets - Current Liabilities) – measures profitability relative to capital employed.
9. ROE = Net Income / Total Shareholders' Equity – measures profitability relative to shareholders' equity.
10. In M&M Proposition I (no taxes), firm value is independent of capital structure – but with taxes, value increases with debt due to the interest tax shield.
