What is Capital Structure and How is it Related to Credit Health?

A company’s capital structure, combined with credit health, can drive the company forward regarding revenues, earnings, and cash flows. How the company chooses to fund growth goes a long way toward ultimate success.

When investors search for investment quality, starting with the story, a balance sheet tells investors about the capital structure and how the company funds its growth.

Analyzing the balance sheet and determining the credit health of a company helps define a strong investment and a company going on the right path.

In today’s post, we will learn:

Okay, let’s dive in and learn more about credit health and capital structure.

What is Capital Structure (Terminology)?

Capital structure describes the particular mix of debt and equity a company uses to finance operations and growth.

Debt refers to bond issues or loans, and equity describes capital raised from selling shares of common stock, preferred stock, or retained earnings.

A company’s wise use of debt and equity indicates a strong balance sheet. A healthy capital structure reflects low debt levels, and high equity levels equal an excellent company.

If you are an investor who likes fundamentals, like we do, finding companies with strong balance sheets helps investors invest with a margin of safety.

Okay, let’s define some terms to understand the capital structure and credit health better.

Capital Structure

The capital structure of Visa describes its long-term capital, consisting of a mixture of debt and equity. Visa’s capital structure starts as a permanent support funding for operations and growth.

We can express Visa’s capital structure as a formula:

Captial Structure = DO + TSE


DO = debt obligations

TSE = total shareholders’ equity

Many investors refer to the capital structure as capitalization or capitalization structure.

A great way to think about capital structure creating value with the best optimal proportion of debt and equity remains by utilizing the above formula to find the best mixture.

The easiest component of the capital structure to measure remains the company’s equity. The company’s equity contains a mixture of common and preferred stock plus retained earnings.

The above mix encompasses the company’s invested capital, and the numbers appear in the shareholders’ equity section of the balance sheet.

The capital structure equals the invested capital plus any debt. For example, Visa has total debt of $20.9 billion and shareholders’ equity of $37.9 billion, giving the company a capital structure of $58.8 billion.


The dialogue surrounding debt tends towards a little less clear talk. Much of the finance literature discusses company debt as part of the company’s liabilities. By categorizing everything as a debt, we ignore the divide between operational and debt liabilities. The debt liabilities form the basis of the debt component of Visa’s capital structure.

Many investors and analysts focus on the long-term debt components as the entirety of the company’s debt. But this meaning doesn’t account for short-term debt, operating leases, or other debt obligations. Focusing on the long-term debt equates to a short-term answer or a quick fix, but using the whole gamut of debt gives us a better insight.

The main component of a company’s debt refers to bonds a company uses to raise funds for various projects. Companies use their credit ratings to get favorable rates to offer investors in exchange for their investments.

The better a company’s credit rating, the lower the interest rate the company can offer, which might seem counterintuitive, but the higher credit rating also indicates financial strength and the likelihood of repayment. We will discuss this more in-depth in a moment.

Along with long-term debt via bonds, another option for companies wishing to raise funds comes from short-term commercial paper.

Short-term commercial paper represents loans companies can use for day-to-day working capital needs, for example, payroll or utility bills.

What Are the Three Types of Capital Structure?

The three main types of capital a company might use to finance projects:

  • Debt Capital
  • Equity Capital
  • Working Capital

Okay, let’s explore these three types of capital to better understand how a company might structure its capital.

Debt Capital

Any company can acquire capital via borrowing. Companies can obtain debt capital through private or government sources.

The most common avenue for established companies comes from issuing bonds or borrowing from financial institutions. Companies also use banks for capital borrowing as well.

The most common funding source for smaller companies or startups remains friends, family, credit cards, and online lenders.

But like individuals, companies rely on good credit scores to obtain debt capital. To obtain favorable credit means paying their bills on time, in this case, interest payments on any debt the company acquires.

The interest rates will vary depending on the company’s credit rating—the better the rating, the lower the rates.

For example, companies with a credit rating of AA (Moody’s scale) can obtain better financing at lower rates than a company with a credit rating of BB.

As individuals, we might see debt as a burden to overcome. But companies see the debt capital as an opportunity. Many companies use debt to help finance growth. For example, Roper Technologies, a serial tech acquirer, uses debt capital to help them acquire small tech companies to boost growth.

In times of low rates, during the period between 2009 to 2022, issuing bonds was a favorite way for companies to raise debt capital.

According to Moody’s Analytics, one of the leading bond rating agencies, corporate bond offerings grew 70% in 2020 compared to 2019. As the amount of debt issued grew, the rates charged for the debt fell to a multi-year low of 2.3%.

Equity Capital

Equity capital represents the easiest capital to define and comes in several forms—the most common forms of equity equal private, public, and real estate equity.

Private and common equity come in the flavor of shares of stock with the company.

The difference between the two comes from the source of equity. Public equity stems from raising funds from listing shares on a stock exchange, like the Dow Jones. Private equity raises funds from a close group of investors, offering cash in exchange for shares in the private company.

When investors buy shares of Visa, they provide Visa with equity capital in the form of their cash investment.

The biggest influx of equity capital comes when a company issues an IPO (initial public offering). 2021 saw the largest number of IPOs in history, raising $286 billion from IPOs and SPACs.

Credit ratings also impact equity financing in that they influence whether a company can raise capital via debt or equity by the cheapest means possible.

For example, if a company with a good credit rating can raise capital via debt versus equity at a cheaper rate, it makes more sense to use the cheaper source of financing to grow.

Typically, debt financing remains a cheaper source of capital than equity financing, but much depends on the company’s credit rating and place in the market.

Working Capital

Visa’s working capital equals the liquid capital assets available to Visa’s management to operate the company daily.

We can calculate the working capital thru two methods:

  • The current ratio, which equals current assets relative to the current liabilities
  • Working capital equaling accounts receivable plus inventory less any accounts payable.

Working capital measures Visa’s short-term cash, focusing on the company’s ability to cover the debt, account payable, and any other obligations due within a year.

The current ratio remains the most common form in finance for measuring working capital. It can tell an investor whether a company has the cash to cover its operating costs in the short term.

What is a Healthy Capital Structure?

There remains no magic bullet telling investors or management what ratio between debt and equity a company should use as guidance.

The definition of the healthy blend between debt and equity depends on the industry, type of business, and where the company sits in its life cycle.

For example, a company in the utility industry relies heavily on debt to finance its growth, as does the real estate industry. But REITs also utilize a heavy mixture of equity cash to generate growth.

And young companies without a ton of credit history might have larger adoption of equity than debt. In contrast, an established company with a single A rating from Moody’s might choose debt.

And then you have extreme examples like Constellation Software which chooses to use working capital or free cash flow to generate growth. As a company relying on a great deal of M&A (mergers and acquisition) activity to drive growth, they choose to finance the growth via its operations and integrate those acquisitions seamlessly.

Unfortunately, as investors, nothing characterizes the ideal mix; instead, we need to rely on our experience, other analysts’ views, and several ratios.

For example, the ratio most often cited as a good metric to measure the ideal mix remains debt-to-equity, but it contains challenges as with any metric.

The debt-to-equity comes with the issue of representing too large of scope and including operational liabilities.

The debt to asset ratio carries the same issue, too broad of a scope.

Two ratios I like to use:

  • Capitalization ratio – divides long-term debt by long-term debt plus shareholders’ equity. This ratio helps give key insight into Microsoft’s capital position
  • Cost of capital – a little more inside baseball kind of metric, which gives insight into the cost of debt and cost of equity and then weighs them compared to the company’s market cap. This ratio gives great insight into the costs associated with financing, which drives which projects management chooses and how to finance them.

We can also use the Dupont model or analysis to understand the capital structure better.

For example, Texas Instruments can borrow money at 5% for 30 years, the inflation rate sits at 3%, and the company can reinvest the money in core operations generating a 20% return.

In the above scenario, it makes sense for Texas Instruments to go into debt.

It would make sense for Texas Instruments to carry at least 40 to 50% of debt capital, especially if their sales and costs remain stable.

But many of those decisions rely on management experience, operational efficiency, and the type of industry the company operates.

What Role Does Credit Health Play in Capital Structure?

To help investors understand the strength of a company’s balance sheet, we can use the credit rating agencies whose primary job focuses on risk assessment.

The big three credit rating agencies conduct a risk assessment of publicly traded companies:

These companies evaluate whether a company can repay principal and interest on any debt, primarily bonds and commercial paper.

These companies use a letter grading system to give each company a score based on the company’s financial strength.

For example, AAA remains the top rating for Moody’s, of which only three companies carry:

  • Microsoft (MSFT)
  • Johnson & Johnson (JNJ)
  • Apple (AAPL)

The credit rating agencies split the public companies into investment and non-investment grades. These ratings give a lot of insight into the financial strength of the particular companies, along with the possible interest rates offered on bonds.

Generally, companies with investment grades carry lower interest rate debt, corresponding to more cash flow. And likewise, non-investment grades lead to higher interest rates and poorer free cash flow.

The credit ratings agencies have access to information not available to the general public. For example, they have access to business plans, capital expenditures, and future dividend plans.

All of the extra information helps the big three make determinations on the company’s credit rating.

Many studies reveal companies’ CFOs consider credit ratings highly relevant and use the information as part of their decision-making process. They also watch any changes in credit ratings and companies under watch by rating agencies.

Companies with higher credit ratings tend towards lower capital costs and higher levels of leverage to generate growth. In comparison, companies in the non-investment grade carry higher debt costs and lower levels of leverage or debt.

We can use credit ratings as a proxy for balance sheet strength. Companies with higher ratings tend to have stronger financials and lower capital costs.

When analyzing a company, a great practice remains to look up the company’s credit ratings at one of the big three. I use Moody’s as my main choice but have accounts with all three as they remain free.

Investor Takeaway

Visa’s capital structure contains a mixture of debt and equity on its balance sheet. Though there remains no ideal mix for a healthy company, generally accepted rules include lower debt and higher equity levels.

We can use various ratios such as debt-to-equity and capitalization ratios to help us analyze a company’s capital structure. We can compare those results to peers and historical numbers for past performance.

Combining those ratios with the ratings from Moody’s, for example, helps give us good insight into the capital mix the company chooses to utilize.

Using our tools to analyze a company’s capital structure and the insights from the rating agencies will help investors find strong companies. These tools also give us insight into management and their decisions to grow the business.

Capital allocation remains the top job for the CEO and management. Companies making poor capital allocation will probably struggle in the markets. A good study of the capital allocation skills of various CEOs such as Warren Buffett, Jeff Bezos, Mark Leonard, and others would offer great insights into what to look for in a leader.

And with that, we will wrap up our discussion on credit health and capital structure.
