The Two Pillars of Corporate Financing
Every business requires capital to operate, expand, and sustain its activities. When analyzing corporate finance, managers must clearly define both the sources of these funds and the associated costs. Broadly speaking, a firm can raise money through two primary avenues: Equity and Debt. Understanding the nuances of these sources, alongside calculating their respective costs, forms the bedrock of strategic financial management.
1. Equity Financing
Equity involves raising capital by selling ownership stakes in the business. Companies can obtain equity through several methods, such as issuing ordinary shares to investors via an Initial Public Offering (IPO), securing funds from venture capitalists, or retaining earnings. Retained earnings are the profits a company chooses to reinvest in the business rather than distributing them to shareholders as dividends. Another common method is a “Rights Issue,” where a company offers existing shareholders the right to buy additional shares at a discounted price compared to the current market value. Because equity investors assume higher risk—they hold a residual claim on assets in the event of liquidation—they naturally demand higher potential returns.
2. Debt Financing
Unlike equity, debt involves borrowing money that must be repaid with interest over a predetermined period. This can take the form of short-term loans, overdrafts, or long-term bonds. Debt providers assume less risk because they have a prioritized legal claim over the company’s assets. As a result, the cost of debt is generally lower than the cost of equity. The mix of a company’s equity and debt forms its capital structure, leading to the calculation of the Weighted Average Cost of Capital (WACC), which represents the overall cost the firm pays to fund its operations.
Calculating the Cost of Equity (Ke)
In financial literature, the cost of equity is universally denoted as Ke, while the cost of debt is denoted as Kd. To determine the exact cost of equity, financial analysts primarily rely on two major models: the Capital Asset Pricing Model (CAPM) and the Dividend Valuation Model (DVM).
The Dividend Valuation Models
The Dividend Valuation Model theorizes that the price of a company’s stock is essentially the present value of all its future dividend payments. Within this framework, there are two distinct scenarios to consider:
- The Constant Dividend Model: This formula applies when a company pays a flat, unchanging dividend year after year. The formula is simply the dividend divided by the current market price of the share.
- The Constant Growth Dividend Model: Most healthy companies strive to increase their dividends over time. When a question specifies a growth rate (denoted as g), the constant growth formula (also known as the Gordon Growth Model) is deployed. The core formula isolates the share price (Po) by dividing the next period’s expected dividend by the difference between the cost of equity (Ke) and the growth rate (g).
By algebraically manipulating this formula, analysts can make the cost of equity (Ke) the subject of the equation, allowing them to determine exactly what return shareholders expect given the current market price and dividend growth projections.
Cum-Dividend vs. Ex-Dividend Pricing
One of the trickiest obstacles in dividend valuation is understanding market share prices in relation to upcoming dividend payouts. Financial questions frequently use terms like “cum-dividend” (cumulative dividend) and “ex-dividend” (excluding dividend).
When a share is priced cum-dividend, the quoted market price includes the value of a dividend that has been declared but not yet paid out. If you buy the stock at this price, you are entitled to receive that impending cash payout. However, for the purposes of the Dividend Valuation Model, using a cum-dividend price will artificially inflate and distort the underlying valuation of the equity.
The correct figure to use is always the ex-dividend price, which represents the true underlying value of the share stripped of the pending cash distribution. To convert a cum-dividend price into an ex-dividend price, an analyst must simply subtract the value of the impending dividend from the quoted market price. Once this true ex-dividend price is established, it can be accurately plugged into the constant growth formula to derive the precise cost of equity capital.
