Financing assets with debt and equity
Financing assets with debt and equity
Capital Structure refers to the amount of debt and/or equity employed by a firm to fund its operations and finance its assets. The structure is typically expressed as a debt-to-equity or debt-to-capital ratio.
Debt and equity capital are used to fund a business’ operations, capital expenditures, acquisitions, and other investments. There are tradeoffs firms have to make when they decide whether to raise debt or equity and managers will balance the two try and find the optimal capital structure.

The optimal capital structure of a firm is often defined as the proportion of debt and equity that result in the lowest weighted average cost of capital (WACC) for the firm. This technical definition is not always used in practice, and firms often have a strategic or philosophical view of what the structure should be.
In order to optimize the structure, a firm will decide if it needs more debt or equity and can issue whichever it requires. The new capital that’s issued may be used to invest in new assets or may be used to repurchase debt/equity that’s currently outstanding as a form or recapitalization.
Below is an illustration of the dynamics between debt and equity from the view of investors and the firm.
Debt investors take less risk because they have the first claim on the assets of the business in the event of bankruptcy. For this reason, they accept a lower rate of return, and thus the firm has a lower cost of capital when it issues debt compared to equity.
Equity investors take more risk as they only receive the residual value after debt investors have been repaid. In exchange for this risk equity investors expect a higher rate of return and therefore the implied cost of equity is greater than that of debt.
A firm’s total cost of capital is a weighted average of the cost of equity and the cost of debt, known as the weighted average cost of capital (WACC).
The formula is equal to:
WACC = (E/V x Re) + ((D/V x Rd) x (1 – T))
E = market value of the firm’s equity (market cap)
D = market value of the firm’s debt
V = total value of capital (equity plus debt)
E/V = percentage of capital that is equity
D/V = percentage of capital that is debt
Re = cost of equity (required rate of return)
Rd = cost of debt (yield to maturity on existing debt)
T = tax rate
Capital structures can vary significantly by industry. Cyclical industries like mining are often not suitable for debt, as their cash flow profiles can be unpredictable and there is too much uncertainty about their ability to repay the debt.
Other industries like banking and insurance use huge amounts of leverage and are their business models require large amounts of debt.
Private companies may have a harder time using debt over equity, particularly small business which are required to have personal guarantees from their owners.
A firm that decides they should optimize their capital structure by changing the mix of debt and equity has a few options to effect this change.
Each of these three methods can be an effective way of recapitalizing the business.
In the first approach, the firm borrows money by issuing debt and then uses all that capital to repurchase shares from its equity investors. This has the effect of increasing the amount of debt and decreasing the amount of equity on the balance sheet.
In the second approach, the firm will borrow money (i.e. issue debt) and use that money to pay a one-time special dividend, which has the effect of reducing the value of equity by the value of the divided. This is another method of increasing debt and reducing equity.
In the third approach, the firm moves in the opposite direction and issues equity by selling new shares, then takes the money and uses it to repay debt. Since equity is costlier than debt, this approach is not desirable and often only done when a firm is overleveraged and desperately needs to reduce its debt.
There are many tradeoffs that owners and managers of firms have to consider when determining their capital structure. Below are some of the tradeoffs that should be considered.
Watch this short video to quickly understand the main concepts covered in this guide, including the definition of capital structure, what is the optimal capital structure, and the calculation of weighted average cost of capital (WACC).
When firms execute mergers and acquisitions the capital structure of the combined entities can often undergo a major change. There resulting structure will depend on many factors, including the form of consideration provided to the target (cash vs shares) and whether existing debt for both companies is left in place or not.
For example, if Elephant Inc decides to acquire Squirrel Co using its own shares as the form of consideration it will increase the value of equity capital on its balance sheet. If, however, Elephant Inc uses cash (which it financed with debt) to acquire Squirrel Co, it will have increased the amount of debt on its balance sheet.
Determining the pro forma capital structure of the combined entity is a major part of M&A financial modeling. The screenshot below shows how two companies are combined and recapitalized to produce an entirely new balance sheet.

In a leveraged buyout (LBO) transaction a firm will take on significant leverage to finance the acquisition. This practice is commonly performed by private equity firms seeking to invest the smallest possible amount of equity and finance the balance with borrowed funds.
The image below demonstrates how the use of leverage can significantly increase equity returns as the debt is paid off over time.
