A company's debt, liabilities and risk are very important factors in understanding the company. Having an understanding of a company's debt and liabilities is a key component in understanding the risk of a company, thus aiding in the decision to invest, not to invest, or to stay invested in a company. There are many metrics involved in understanding the debt of a company, but for this article, I will look at **Exxon Mobil Corporation**'s (NYSE:XOM) total debt, total liabilities, debt ratios and WACC.

Through the above-mentioned four main metrics, we will understand more about the company's debt, liabilities and risk. If this summary is compared with other companies in the same sector, you will be able see which has the most debt and the most risk.

*1. Total Debt = Long-Term Debt + Short-Term Debt*

Debt is an amount of money borrowed by one party from another, and must be paid back. Total debt is the sum of long-term debt, which is debt that is due in one year or more, and short-term debt, which is any debt that is due within one year.

- 2007 - $7.183 billion + $2.383 billion = $9.566 billion
- 2008 - $7.025 billion + $2.400 billion = $9.425 billion
- 2009 - $7.129 billion + $2.476 billion = $9.605 billion
- 2010 - $12.227 billion + $2.787 billion = $15.014 billion
- 2011 - $9.322 billion + $6.949 billion = $17.033 billion

Exxon Mobil's total debt has increased over the past five years. The company reported a five-year low of $9.425 billion in 2008, and a five-year high in 2011 at $17.033 billion. In 2011, the company reported a total debt of $17.033 billion, which was an increase of 78.06% over 2007.

*2. Total Liabilities*

Liabilities are a company's legal debts or obligations that arise during the course of business operations, so debts are one type of liability, but not all liabilities. Total liabilities is the combination of long-term liabilities, which are the liabilities that are due in one year or more, and short-term or current liabilities, which are any liabilities due within one year.

- 2007 - $120.320 billion
- 2008 - $115.087 billion
- 2009 - $122.754 billion
- 2010 - $155.671 billion
- 2011 - $176.656 billion

Exxon Mobil's liabilities have increased from $120.320 billion in 2007, to $176.656 billion in 2011, an increase of 46.82%.

In analyzing the company's total debt and liabilities, we can see that the company currently has a moderate amount of debt at $17.033 billion and a very large amount of liabilities at $176.656 billion. Over the past five years, the total debt has increased by 78.06%, while total liabilities have increased by 46.82%. As the company's has a moderate amount of debt and a very large amount of liabilities, the next step will reveal if the company has the ability to pay for their debt and liabilities.

**Debt Ratios**

*3. Total Debt to Total Assets Ratio = Total Debt / Total Assets*

This is a metric used to measure a company's financial risk by determining how much of the company's assets have been financed by debt. It is calculated by adding short-term and long-term debt and then dividing by the company's total assets.

A debt ratio of greater than 1 indicates that a company has more total debt than assets; meanwhile, a debt ratio of less than 1 indicates that a company has more assets than total debt. Used along with other measures of financial health, the total- debt-to-total-assets ratio can help investors determine a company's level of risk.

- 2009 - $9.605 billion / $233.323 billion = 0.04
- 2010 - $15.014 billion / $302.510 billion = 0.05
- 2011 - $17.033 billion / $331.052 billion = 0.05

As Exxon Mobil's total-debt-to-total-assets ratio is very low and well below 1, this indicates that Exxon has many more assets than total debt, ensuring that the company is currently in good financial condition.

*4. Debt ratio = Total Liabilities / Total Assets*

Total liabilities divided by total assets. The debt ratio shows the proportion of a company's assets that are financed through debt. If the ratio is less than 0.5, most of the company's assets are financed through equity. If the ratio is greater than 0.5, most of the company's assets are financed through debt. Companies with high debt/asset ratios are said to be "highly leveraged." A company with a high debt ratio or that is "highly leveraged" could be in danger if creditors start to demand repayment of debt.

- 2009 - $122.754 billion / $233.323 billion = 0.52
- 2010 - $155.671 billion / $302.510 billion = 0.51
- 2011 - $176.656 billion / $331.052 billion = 0.53

In looking at Exxon's total liabilities to total assets ratio, we can see that the ratio has remained almost the same over the past 3 years. As these numbers are just over the 0.50 mark, this indicates that Exxon has financed a large amount of the company's assets through debt. As Exxon's debt ratio is below 1 this implies that the company is not in danger of becoming insolvent and/or going bankrupt.

*5. Debt to Equity Ratio = Total Liabilities / Shareholders' Equity*

The debt-to-equity ratio is another leverage ratio that compares a company's total liabilities with its total shareholders' equity. This is a measurement of how much suppliers, lenders, creditors and obligators have committed to the company versus what the shareholders have committed.

A high debt-to-equity ratio generally means that a company has been aggressive in financing its growth with debt. This can result in the company reporting volatile earnings. In general, a high debt-to-equity ratio indicates that a company may not be able to generate enough cash to satisfy its debt obligations, and therefore is considered a riskier investment.

- 2009 - $122.754 billion / $110.569 billion = 1.11
- 2010 - $155.671 billion / $146.839 billion = 1.06
- 2011 - $176.656 billion / $154.396 billion = 1.14

Over the past three years, Exxon Mobil's debt-to-equity ratio has been moderate ranging between 1.14 and 1.06. In 2011, the ratio was calculated at 1.14, as the ratio was slightly above 1 this indicates that suppliers, lenders, creditors and obligators have slightly more equity invested than shareholders; 1.14 indicates a moderate amount of risk for the company. As the ratio is slightly above 1 and considered moderate, so is the risk for the company.

*6. Capitalization Ratio = LT Debt / LT Debt + Shareholders' Equity*

(LT Debt = Long-Term Debt)

The capitalization ratio tells the investors about the extent to which the company is using its equity to support its operations and growth. This ratio helps in the assessment of risk. Companies with a high capitalization ratio are considered to be risky because they are at a risk of insolvency if they fail to repay their debt on time. Companies with a high capitalization ratio may also find it difficult to get more loans in the future.

- 2009 - $7.129 billion / $117.698 billion = 0.06
- 2010 - $12.227 billion / $159.006 billion = 0.08
- 2011 - $9.322 billion / $163.718 billion = 0.06

Over the past three years, Exxon Mobil's capitalization ratio has been between .06 to .08. This implies that the company has had relatively the same amount of equity compared with its long-term debt. As this is the case, the company has had around the same amount of equity to support its operations and add growth through its equity. As the ratio has been relatively the same and is very low so has the company's risk.

*7. Interest Coverage Ratio = EBIT (Earnings before interest and taxes) / Interest Expenses*

The interest coverage ratio is used to determine how easily a company can pay interest expenses on outstanding debt. The ratio is calculated by dividing a company's earnings before interest and taxes (EBIT) by the company's interest expenses for the same period. The lower the ratio, the more the company is burdened by debt expense; the higher the ratio the better. When a company's interest coverage ratio is 1.5 or lower, its ability to meet interest expenses may be questionable.

- 2010 - $35.325 billion / $548 million = 64.46
- 2010 - $53.218 billion / $259 million = 205.47
- 2011 - $73.504 billion / $247 million = 279.58

Exxon's interest coverage ratio has ranged between 64.46 and 279.58 over the past 3 years. As the interest ratio has been well over 1.5, this implies that the company is not burdened by debt expenses.

*8. Cash Flow to Total Debt Ratio = Operating Cash Flow / Total Debt*

This coverage ratio compares a company's operating cash flow with its total debt. This ratio provides an indication of a company's ability to cover total debt with its yearly cash flow from operations. The higher the percentage ratio, the better the company's ability to carry its total debt. The larger the ratio, the better a company can weather rough economic conditions.

- 2009 - $28.438 billion / $9.605 billion = 2.96
- 2010 - $48.413 billion / $15.014 billion = 3.22
- 2011 - $55.345 billion / $17.033 billion = 3.25

Over the past three years, the cash flow to total debt ranged between 2.96 to 3.25. As the ratio is well above 1 this implies that the company had the ability to cover its total debt with its yearly cash flow from operations.

Based on the above six debt ratios, we can see that Exxon Mobil has extremely strong results in regards to its debt ratios. As the ratios results are very strong, this indicates that Exxon has the ability to pay for its debt, is not burdened by tax expenses, has the ability to cover its total debt from operating cash flow and is not on the verge of bankruptcy. The next step will reveal how much the company will pay for the debt incurred.

**Cost of Debt**

The cost of debt is the effective rate that a company pays on its total debt.

As a company acquires debt through various bonds, loans and other forms of debt, the cost of debt metric is useful, because it gives an idea as to the overall rate being paid by the company to use debt financing.

This measure is also useful because it gives investors an idea as to the riskiness of the company compared with others. The higher the cost of debt the higher the risk.

*9. Cost of debt (before tax) = Corporate Bond rate of company's bond rating.*

- S&P rated Exxon's bonds "AAA"
- Current 20-year corporate bond Rate of "AAA" = 3.72%
- Current cost of Debt as of September 6th 2012 = 3.72%

According to the S&P rating guide, the "A" rating is - "Extremely strong capacity to meet financial commitments. Highest Rating" Exxon Mobil has a rating that meets this description.

*10. Current tax rate ( Income Tax total / Income before Tax)*

- 2007 - $29.864 billion / $70.474 billion = 42.37%
- 2008 - $36.530 billion / $81.750 billion = 44.68%
- 2009 - $15.119 billion / $34.777 billion = 43.47%
- 2010 - $21.561 billion / $52.959 billion = 40.71%
- 2011 - $31.051 billion / $73.257 billion = 42.38%

5-year average = 42.72%

Over the past five years, Exxon Mobil has averaged a tax rate of 42.72%.

*11. Cost of Debt (After Tax) = (Cost of debt before tax) (1 - tax rate)*

The effective rate that a company pays on its current debt after tax.

- .0372 x (1 - .4272) = Cost of debt after tax

The cost of debt after tax for Exxon Mobil is *2.13%*

**Cost of equity or R equity =** Risk free rate + Beta equity (Average market return - Risk free rate)

The cost of equity is the return a firm theoretically pays to its equity investors, for example, shareholders, to compensate for the risk they undertake by investing in their company.

- Risk free rate = U.S. 10-year bond = 1.65% (Bloomberg)
- average market return 1950 - 2011 = 7%
- Beta = (Google Finance) Exxon Mobil's beta = 0.52

Risk free rate + Beta equity (Average market return - Risk free rate)

- 1.65 + 0.52 (7-1.65)
- 1.65 + 0.52 x 5.35
- 1.65 + 2.78 = 4.43%

Exxon Mobil has a cost of equity or R Equity of 4.43%. So investors should expect to get a return of 4.43% over the long term on their investment to compensate for the risk they undertake by investing in this company.

(*Please note that this is the CAPM approach to finding the cost of equity. Inherently, there are some flaws with this approach and that the numbers are very "general." This approach is based off of the S&P average return from 1950 - 2011 at 7%, the U.S. 10-year bond for the risk free rate which is susceptible to daily change and Google finance beta.*)

**Weighted Average Cost of Capital or WACC**

The WACC calculation is a calculation of a company's cost of capital in which each category of capital is equally weighted. All capital sources such as common stock, preferred stock, bonds and all other long-term debt are included in this calculation.

As the WACC of a firm increases, and the beta and rate of return on equity increases, this states a decrease in valuation and a higher risk.

By taking the weighted average, we can see how much interest the company has to pay for every dollar it finances.

For this calculation, you will need to know the following listed below:

Tax Rate = 42.72% (Exxon's five-year average Tax Rate)

Cost of Debt (before tax) or **R debt** = 3.72%

Cost of Equity or **R equity** = 4.43%

Debt (Total Liabilities) for 2011 or **D** = $176.656 billion

Stock Price = $88.37 (September 6th, 2012)

Outstanding Shares = 4.62 billion

Equity = Stock price x Outstanding Shares or **E** = $408.269 billion

Debt + Equity or **D+E** = $584.925 billion

**WACC** = R = (1 - Tax Rate) x R debt (D/D+E) + R equity (E/D+E)

(1 - Tax Rate) x R debt (D/D+E) + R equity (E/D+E)

(1 - .4272) x .0372 x ($176.656/$584.925) + .0372 ($408.269/$584.925)

.5728 x .0372 x .3020 + .0372 x .6979

.0064 + .0260

= 3.24%

Based on the calculations above, we can arrive that Exxon Mobil's pays 3.24% on every dollar that it finances or .0324 on every dollar. From this calculation, we understand that on every dollar the company spends on an investment, the company must make $.0324, plus the cost of the investment for the investment to be feasible for the company.

**Summary**

In analyzing the company's total debt and liabilities, we can see that the company currently has a moderate amount of debt at $17.033 billion and a very large amount of liabilities at $176.656 billion. Over the past five years, the total debt has increased by 78.06%, while total liabilities have increased by 46.82%.

Based on the above six debt ratios, we can see that Exxon Mobil has had very strong results in regards to its debt ratios. Based on the strong results from the ratios above, this indicates that Exxon has the ability to pay for its debts.

As Exxon's bond rating currently stands at "AAA" this indicates that the company has a "Extremely strong capacity to meet financial commitments. Highest Rating".

The CAPM approach for cost of equity states that shareholders need 8.90% over a long period of time on their equity to make it worthwhile to invest in the company. This calculation is so based on the average market return between 1950 and 2011 at 7%.

The WACC calculation reveals that the company pays 3.24% on every dollar that it finances. As the current WACC of Exxon is currently 3.24% and the beta is below average at 0.52, it implies that the company needs 3.24% on future investments and will have below average volatility moving forward.

Based on the calculations above, the company has a moderate amount of debt and a very large amount of liabilities, but currently the company has the capacity to make its debts payments, meet its tax obligations and is not in danger of bankruptcy.

The analysis of Exxon Mobil's debt and liabilities indicates a very strong company, with a very manageable amount of debt and liabilities for the company. The analysis also reveals the company is strong and stable in regards to the debt ratios. The WACC reveals that Exxon also and has the ability to add future investments and assets at low rates. Currently, Exxon has the ability to pay for its debts, meet its tax obligations, is not in danger of bankruptcy, and has the opportunity to capitalize on future investments with low risk.
