Components of Stockholders’ Equity
Stockholders’ equity is composed of several key sections, each reflecting different sources and uses of capital:
Contributed Capital: Capital received from shareholders in exchange for stock.
Retained Earnings: Cumulative net income retained in the company, not distributed as dividends.
Treasury Stock: Shares repurchased by the company, recorded as a contra-equity account.
Accumulated Other Comprehensive Income (AOCI): Cumulative net gains/losses from specific items not included in net income.
Capital Stock: Authorized, Issued, and Outstanding Shares
Definitions
Corporations issue shares of stock to raise capital. The terminology surrounding shares is important for understanding equity structure:
Authorized Shares: Maximum number of shares a corporation can legally issue.
Issued Shares: Shares that have been sold to investors.
Outstanding Shares: Issued shares currently held by shareholders (not including treasury shares).
Treasury Shares: Issued shares reacquired by the corporation.
Type | Description |
|---|---|
Authorized Shares | Maximum allowed by corporate charter |
Issued Shares | Sold to investors |
Outstanding Shares | Held by shareholders |
Treasury Shares | Reacquired by company |

Common Stock
Characteristics
Common stock represents basic ownership in a corporation and confers several rights and responsibilities:
Voting Rights: Common shareholders typically vote on major corporate matters.
Residual Value: Entitled to residual assets after obligations are met.
Limited Liability: Shareholders are not personally liable for corporate debts.
Par Value: Nominal value assigned to shares; often set very low.
Issuing Common Stock
Common stock can be issued with or without par value. The accounting treatment differs accordingly:
Without Par Value: Entire proceeds credited to common stock.
With Par Value: Par value credited to common stock; excess credited to Additional Paid-In Capital (APIC).
Example (With Par Value):
Issue 5,000 shares at $10 each, $1 par value:
Journal Entry: Dr. Cash $50,000 Cr. Common Stock $5,000 Cr. APIC $45,000
Preferred Stock
Characteristics and Preferences
Preferred stock is a class of stock with specific rights and preferences, often including:
Dividend Preference: Paid before common dividends.
Cumulative Dividends: Unpaid dividends accumulate and must be paid before common dividends.
Bankruptcy Preference: Paid before common shareholders in liquidation.
Limited Voting Rights: Usually none unless specified.
Example (Cumulative Preferred Dividend):
Preferred dividend per year:
Year 11: Pay 3 years’ dividends (9), common receives remainder.
Treasury Stock
Definition and Purpose
Treasury stock consists of shares reacquired by the corporation. It is a contra-equity account and reduces total equity.
No Voting or Dividend Rights: Treasury shares do not participate in voting or dividends.
Recorded at Cost: When reacquired, recorded at purchase price.
Reasons for Buyback: Alternative to dividends, increase EPS, meet option requirements, perceived undervaluation.

Retained Earnings
Definition and Link to Financial Statements
Retained earnings represent the cumulative net income retained by the company, not distributed as dividends. It links the income statement to the balance sheet.
Formula:
Dividends: Subtracted directly from retained earnings, not treated as an expense.
Dividends
Types and Key Dates
Dividends are distributions of earnings to shareholders. They become legal obligations only after declaration by the board.
Cash Dividends: Most common; paid in cash.
Stock Dividends: Paid in additional shares; discussed in advanced courses.
Key Dates: Declaration Date (liability recorded), Date of Record (no entry), Payment Date (cash paid).
Other Comprehensive Income (OCI) and Accumulated OCI (AOCI)
Definition
OCI includes gains and losses from specific sources not included in net income, such as unrealized gains/losses on certain securities, foreign currency translation, derivative hedges, and pension adjustments. AOCI is the cumulative net OCI reported on the balance sheet.
Statement of Stockholders’ Equity
Format and Purpose
The statement of stockholders’ equity summarizes changes in equity accounts over a period. It reconciles beginning and ending balances and links to the balance sheet.
Format: Beginning balances, changes during period, ending balances.
Purpose: Provides transparency regarding equity transactions.
