The Capital Structure Decision
Capital structure — the combination of debt and equity that a company uses to finance its assets and operations — is one of the most consequential decisions in corporate finance because it affects both the cost of capital and the risk profile of the business. The company financed primarily with equity has a higher cost of capital than one that uses debt (because equity investors require higher returns than debt investors due to their lower priority in the capital structure) but lower financial risk (because equity has no mandatory repayment obligation that could cause financial distress if business performance declines). The optimal capital structure balances these trade-offs in a way that minimises the cost of capital while maintaining adequate financial flexibility.
The capital structure theory that most directly informs practice: the trade-off theory, which holds that the optimal debt level is determined by the trade-off between the tax benefit of debt (interest payments are tax-deductible, reducing the tax bill relative to all-equity financing) and the cost of financial distress (the increasing probability and cost of bankruptcy or financial distress as debt levels rise). In practice, most companies target a capital structure that maintains investment-grade credit ratings while taking advantage of the tax deductibility of interest — a range that provides the tax benefit without raising the cost of financial distress to a level that offsets it.
How Companies Raise Capital
The capital raising mechanisms available to publicly traded companies: equity issuance through secondary offerings (selling new shares to public market investors, which dilutes existing shareholders but raises equity capital without a repayment obligation), debt issuance through bonds or bank loans (borrowing at a fixed or variable interest rate with a defined repayment schedule, which does not dilute existing shareholders but creates a fixed financial obligation), and hybrid instruments such as convertible notes (which begin as debt and convert to equity under defined conditions, providing the company with initial debt capital at a lower interest rate in exchange for the investor’s option to convert to equity if the company performs well).
The capital raising decision that most affects the company’s subsequent strategic flexibility: the debt maturity structure. The company that finances a significant portion of its capital needs with short-term debt that matures frequently must refinance regularly, exposing itself to the risk that market conditions at refinancing time are unfavourable. The one that matches the maturity of its debt to the longevity of the assets the debt is financing — long-term assets funded with long-term debt — reduces this refinancing risk and maintains the financial flexibility that allows management to focus on the business rather than on the funding.
Dividend Policy and Capital Allocation
The dividend policy decision — whether to return cash to shareholders through dividends or share buybacks, or to retain and reinvest it in the business — is a core corporate finance decision that communicates the management team’s assessment of the company’s investment opportunities. The company that pays a high dividend is signalling that it does not have enough attractive investment opportunities to justify retaining all of its cash flow; the one that pays no dividend and reinvests everything is signalling the opposite — that it has investment opportunities whose expected returns exceed what shareholders could earn by reinvesting the dividend themselves.
The share buyback mechanism that most effectively returns capital to shareholders when the company’s stock is trading below intrinsic value: the open market repurchase programme, in which the company repurchases its own shares in the market over an extended period. The buyback at a price below intrinsic value creates value for remaining shareholders by reducing the share count while purchasing each share for less than it is worth. The buyback at a price above intrinsic value destroys value for the same reason — it is a poor use of capital that benefits only the shareholders who sell into the buyback.
Mergers and Acquisitions as Capital Allocation
The corporate finance perspective on mergers and acquisitions: an acquisition is a capital allocation decision in which management proposes to invest a specific amount of capital in a specific asset at a specific price, with an expected return based on the target’s performance and the synergies the combination will produce. Evaluated as a capital allocation decision, the acquisition must be compared against alternative uses of the same capital — organic investment in internal projects, return of capital to shareholders through dividends or buybacks, or simply holding cash — and the acquisition should be pursued only if its expected risk-adjusted return exceeds the returns available from alternative capital uses.
The acquisition valuation discipline that most consistently produces value-creating M&A: the rigorous distinction between the target’s standalone value and the incremental value the combination will create through synergies, evaluated separately and priced separately. The acquiring company that can create synergies that no other potential acquirer can create as effectively — proprietary synergies — can justify paying above the competing bidder’s maximum price. The one that is bidding against competitors with similar synergy potential should limit its price to a level that leaves enough synergy value for the acquiring shareholders rather than allowing competition to transfer all synergy value to the seller.
Risk Management in Corporate Finance
The corporate finance risk management functions that most directly protect business value: interest rate hedging (the use of financial derivatives to reduce the risk that rising interest rates will increase the cost of variable-rate debt), foreign currency hedging (the use of forward contracts, options, or natural hedges to reduce the risk that exchange rate movements will reduce the value of foreign revenues or increase the cost of foreign inputs), and commodity price hedging (the use of futures contracts to reduce the risk that input price increases will compress margins in businesses where commodity costs are a significant portion of cost of goods sold).
The risk management principle that most guides corporate hedging decisions: hedge the risks that are significant enough to materially affect the business’s financial performance and that are not central to the business’s value proposition, while accepting the risks that are central to the value proposition. The airline that hedges fuel costs is managing a risk that is large relative to its margins and not central to its value proposition (its value proposition is transportation service, not energy market exposure). The commodity trading firm that hedges commodity price risk is eliminating the exposure that is the source of its competitive advantage and value proposition — a category error that would eliminate the reason for its existence.
