Overview of financial ratios

Liquidity ratios

Current ratios measure liquidity, which refers to the ability of the firm to meet its short-term debt obligations. The formula for current ratio is as follows:

Current ratio=Current assets/Current liabilities

A positive current ratio is a must. A current ratio of at least two is generally advisable. If a company has current ratio of two, it means that it has current assets which would be able to cover current liabilities twice.

Activity ratios

Total asset turnover calculates how efficiently assets are used to generate sales. In other words, how efficiently the balance sheet is managed.

Total asset turnover=Sales/Total assets

The health of this ratio is an important factor which contributes to a healthy return on investment (ROI/ROA).

Inventory turnover ratio measures the liquidity of a firm’s inventory. It measures how many times the company turns over (sells, uses or replaces) its inventory during a period, such as the financial period.

It is calculated by dividing cost of goods sold by inventory.

Inventory turnover ratio = Cost of goods sold/Inventory

The result of this ratio is only meaningful in comparison. It can be compared to industry averages, to firms past inventory turnover ratios and to inventory turnover ratios of competitors.

Industry averages differ significantly between industries for inventory turnover ratio. Inventory turnover is positive (higher than zero) as long as firm has any inventory. Generally high inventory turnover is considered to be a good indicator.

However, the norm would differ significantly between industries. If industry turnover is too high compared to the norm within the industry, it may mean the company keeps too little inventory and, therefore, may lose some sales.

Debt ratios

Debt ratio measures how many of firm’s assets are financed by debt. The formula for debt ratio is as follows:

Debt ratio=Total liabilities/Total assets

For example, assume that ABC’s total liabilities are $1,700,000 and total assets are $4,000,000. The debt ratio of ABC is as follows: $1,700,000/$4,000,000=42.5%

This means that ABC’s capital structure is 42.5% of debt and 57.5% of equity.

Debt-equity ratio measures how much of equity and how much of debt a company uses to finance its assets.

Debt-equity ratio = Total debt / Equity

If the debt-equity ratio is less than one, then it means that equity is mainly used to finance operations. However, if the debt-equity ratio is more than one, then it means that debt is mostly used for financing. If the debt-equity ratio is equal to one, then it means that half of financing comes from debt and half from equity.

The more debt compared to equity the firm uses in financing its assets, the higher the financial risk and the higher potential return. Financial risk refers to risk of firm being forced into bankruptcy if the firm does not meet its debt obligations as they come due.

Times Interest Earned Ratio (Interest Coverage Ratio)

Times Interest Earned Ratio (Interest Coverage Ratio) measures the ability of the enterprise to meet its financial obligations (interest payments on debt that come due). The formula for the Times Interest Earned Ratiois as follows:

TIER=EBIT/interest charges

EBIT refers to earnings before interest and taxes, which is also called operating profit (refer to Income Statement format to see how it is calculated).

For example, assume that ABC has an operating profit of $550,000 and interest charges of $100,000. The TIER of ABC is as follows:

$550,000/$100,000=5.5

One should also compare ratios of individual firms to industry averages, to obtain a better understanding. It is generally advisable that TIER should be between 3 and 5.

ABC’s TIER could be too high. It may be possible that the firm is unnecessarily careful in using debt as a source of capital. This means the risk the firm takes is lower than average, but so is the return.

Profitability ratios

Operating profit margin measures how much of each sales dollar remains after all costs except for interest, tax and preferred dividends are deducted.In other words it measures how efficient the business manages its operations or how efficiently the firm manages its income statement (keeping a healthy balance between sales and costs).

Operating profit margin = Operating profit/Sales

For example, if ABC has a operating profit of $500,000 and sales of $3,000,000 then the operating profit margin is calculated as follows

Operating profit margin = $500,000/$3,000,000

Operating profit margin = 0.167 or 16.7%

The higher the operating profit margin, the better it is.

Return on total assets (ROA) is also called return on investment (ROI). It refers to how effective management is in generating returns on assets of the firm.

ROA/ROI=Earnings available for common stockholders/Total assets

For example, if ABC’s total assets are $3,500,000 and the earnings available for common stockholders is $400,000 than

ROA/ROI=400,000/3,500,000

ROA/ROI=0.11

This means that for every dollar of assets, ABC earned 11 cents. The more the firm earns on every dollar of assets the better.

 

Financial leverage

Financial leverage is the relationship between operating profit and EPS (earnings per share). In short, it measures the level of debt. It is a measure of how the potential use of fixed financial costs (e.g. interest on debt) can enlarge the effect that change in operating profit (EBIT) has on EPS (earnings per share).

When does a firm have financial leverage?

If a firm has mixed financial costs, it has financial leverage. Due to financial leverage (existence of fixed financial costs), any increase in EBIT will result in even larger increases in EPS and any decrease in EBIT will result in even larger decreases in EPS.

How to calculate degree of financial leverage (DFL) of the firm?

To calculate degree of financial leverage, which is just a way to measure financial leverage of the firm, we can follow the following formula:

DFL =% change in EPS/% change in EBIT

Therefore, if the degree of financial leverage is greater than 1, then financial leverage exists (which is the case as long as the company has fixed financial costs). Also, any increase in financial leverage results in an increase in risk and any decrease in financial leverage results in a decrease in risk.

Operating leverage

Operating leverage is the relationship between sales and revenue (Price*Quantity of units sold) and operating profit (which is also called EBIT (earnings before interest and taxes)). It is a measure of how the potential use of fixed costs can enlarge the effect that change in sales volume has on operating profit (EBIT).

We can represent the calculation of operating leverage as follows:

Sales (P * Q)

Less: Fixed operating costs (FC)

Less: Variable operating costs (VC*Q)

= EBIT

Or

EBIT = (P*Q)-FC-(VC*Q)

This simplifies into:

EBIT = Q * (P-VC) – FC

When do firms have operating leverage?

If a firm has fixed costs, it has operating leverage. Because fixed cost (FC) is unchanged, an increase in sales revenue (P*Q) results in a proportionally bigger increase in EBIT (earnings before interest and taxes, which is also called operating profit). However, decrease in sales revenue (P*Q) will result in a proportionally bigger decrease in EBIT.

Increase in operating leverage increases business risk, which is a chance that the business will not be able to cover its operating costs.

How to calculate the degree of operating leverage (DOL) of the firm?

To calculate degree of operating leverage, which is just a way to measure operating leverage of the firm, we can use the following formula:

DOL =% change in EBIT/% change in sales

Therefore, if the degree of operating leverage is greater than 1, than operating leverage exists (which is the case as long as the company has fixed operating costs).

Businesses can increase their operating leverage by substituting variable costs for fixed costs, where possible. For example, salaries to sales personnel could be fixed instead of variable of units sold. Of course, many other variables need to be taken into account to make such a decision, such as consideration of how such changes would affect motivation levels of sales personnel.

Leverage

In finance, leverage (which is also called gearing or levering) refers to the use of debt rather than equity as a source of capital to finance investments and reinvestments. The more debt the business uses the more leverage it has.

As leverage increases, the risks also increase and so does the return on investment. However, as leverage decreases, the risks also decrease as well as the return on investment. Management have almost total control over the risk introduced by increased leverage.

There are three types of leverage:

  • Operating leverage – refers to the relationship between sales revenue and operating profit (which is also called EBIT (earnings before interest and taxes))
  • Financial leverage – refers to the relationship between operating profit and EPS (earnings per share)
  • Combined or total leverage – refers to the relationship between sales revenue and EPS

Weighted Marginal Cost of Capital (WMCC) and Investment Opportunities Schedule

By finding all break points, we can construct the weighted marginal cost of capital – WMCC – schedule. (WMCC) schedules show the relationship between the level of total new financing and a company’s weighted average cost of capital.

Thereafter, we can construct the investment opportunities schedule (IOS), which is a graph where the business’s investment opportunities are ranked based on their returns and financing required, arranged from the highest returns and all the way to the lowest returns. It is the decreasing function of the level of total financing.

If we combine the weighted marginal cost of capital (WMCC) schedule and investment opportunities schedule (IOS), we can use it to make investment decisions. The rule is to invest in projects up to the point on the graph where marginal return from investment equals its WMCC (where IOS=WMCC).

All projects on the left of the point where IOS=WMCC will maximize shareholders wealth and all points on the right of the point where IOS=WMCC will decrease shareholders’ wealth.

It is important to note that the majority of firms stop investing before the marginal return from investment equals its weighted marginal cost of capital (WMCC). Therefore, the majority of businesses prefer a capital rationing position (the position below the optimal investment budget, which is also called the optimal capital budget).

Test yourself


ABC Company has to make an investment of $1,000,000. The long-term debt weight in the capital structure is 35%. ABC has $700,000 of retained earnings but 50% of it must be paid to common stock shareholders in the form of dividends. Preferred stock is currently not used as a source of finance by ABC.

What are the weights that ABC will have for each source of capital?

SOLUTION:

Firstly, we need to find out how much of retained earnings ABC has left after payment of dividends to shareholders: $700,000*0.5=$350,000.

Therefore, the weight of retained earnings is 35% ($350,000 out of $1,000,000).

$1,000,000-$350,000 (35%, funds available from long-term debt source) – $350,000 (35%, funds available from retained earnings) = $300,000 (30%)

Therefore, the weights are as follows:

Long-term debt – 40%

Retained earnings – 35%

Common stock – 30%

Weighted Marginal Cost of Capital (WMCC)

Weighted Marginal Cost of Capital – WMCC – is the WACC applicable to the next dollar of the total new financing. Related to the concept is the break point concept. Weighted average cost of capital (WACC) may change over time due to changes in the volume of financing. This occurs as the volume of financing increases, the risk increases and providers of funds require higher return on the funds that they make available.

The WACC of the next dollar of the total financing may be different from the WACC of the last dollar of the total financing.

(WACC) Weighted average cost of capital (ra)

Weighted average cost of capital (WACC) (ra) is a very simple concept. Weighted average cost of capital (WACC) refers to the weighted cost of both debt and equity financing, according to the firm’s specific optimal mix of financing (debt and equity). Knowing the weighted average cost of capital (WACC) enables better decision making about proposed projects.

The formula for weighted average cost of capital (WACC) (ra) is as follows:

WACC=(wd*rd)+(we*re)+(ws*rn or rr)

Where:

wd = a weight for the long-term debt

we = a weight for the preferred stock

we = a weight for the common stock

rd = the cost of long-term debt

re = the cost of preferred stock

rn = the cost of new common stock

rr = the cost of retained earnings

All sources of capital and their weights must be taken into account.

Example


Project Omega was proposed with an expected return of 9% and the firm’s cost of capital for debt financing is 7% and cost of capital for equity financing is 12%. Further, the optimal mix of debt and equity of the firm is 40 percent of debt and 60 percent of equity. Then, the weighted average cost of capital (WACC) is calculated as follows:

weighted average cost of capital (WACC) = 7% * 0.40 + 12% * 0.60

2.8 + 7.2 = 10%

The weighted average cost of capital (WACC) is 10%.

Given the information above, the proposed project with expected return of 9% should be rejected as it is below the firm’s 10% weighted average cost of capital (WACC).

When making investment decisions, business must only choose projects that bring returns higher than the weighted average cost of capital (WACC).

Test yourself


Company ABC has the following sources of capital:

Long-term debt at 7% after-tax cost with weight of 35% in the capital structure.

Preferred stock at 9% after-tax cost with weight of 10% in the capital structure.

Common stock at 14% after-tax cost with weight of 55% in the capital structure.

REQUIRED: Find the weighted average cost of capital (WACC).

SOLUTION:

weighted average cost of capital (WACC) =7%*.35+9%*.10+14%*.55

WACC=2.45+.9+7.7

WACC=11.05%

Calculating weights


As per above, to calculate the weighted average cost of capital (WACC) we need to know the weight of each source of financing. When calculating weights, market values or book values can be used. Market values evaluate the proportion of capital at the market value and book values evaluate the proportion of capital at the book (accounting) value. It is better to use market values, as it is a more realistic value.

Further, when calculating weights, we can use either target or historical proportions. Target proportions refer to the optimal capital mix that a business would like to achieve. Historical proportion refers to the proportion based on the past. The target proportion is preferred.

***

Weighted average cost of capital (WACC) is a VERY important concept to understand. It is one of the central concepts in business and finance. The basic idea of weighted average cost of capital (WACC) concept is that it shows us the expected average cost of funds in the long-term. Make sure you are comfortable with explanations and calculations of the weighted average cost of capital (WACC) before progressing to the next section.

Finding the after-tax cost of retained earnings (rr)

The cost of retained earnings is the same as the cost of new common stock less flotation costs. Therefore, it is cheaper for businesses to use retained earnings compared to issuing new common stock.

Retained earnings are already earnings after-tax. Therefore, no tax adjustment is required when calculating the cost of retained earnings.

Using CAPM (Capital Asset Pricing Model)

In addition to Gordon Model, another way to find the cost of common stock is by using Capital Asset Pricing Model (CAPM). CAPM allows us to ascertain the relationship between required return and non-diversifiable risk, which is measured by the beta coefficient (b).

Beta coefficient (b) refers to the index that measures non-diversifiable risk (risk which a company cannot eliminate through diversification). It indicates how an asset’s return will react to the changes in the market return, which in turn shows the return on a portfolio of all securities in the market.

Capital Asset Pricing Model (CAPM) is simple, as long as you know the formula and have the information necessary for the formula. The formula is as follows:

rs= Rf+(b*(rm-Rf))

Where:

rs – required return (return on a portfolio or a security)

Rf – risk free rate (e.g. rate on the U.S. Treasury bill)

b – beta coefficient

rm – market return

EXAMPLE:

If Rf (risk free rate) is 5%, beta is 2 and market return (rm) is 12%, the rs (required return or cost of common stock) can be found as follows:

Rs=5%+(2*(12%-5%)

Rs=19%

Test yourself

Assuming we know that beta (company’s market risk coefficient) is 2, market return is 13%, risk free rate of return is 7%, current dividend is $4 and dividend growth over the past 5 years is 5% and the same growth is expected in the future. With CAPM, find the price of the ordinary share.

SOLUTION:

First, using CAPM, we find rs:

rs= Rf+(b*(rm-Rf))

rs=7+(2*(13-7))

rs=19%

Next, we use the Gordon model (P0=D1/(rs-g)) to find the price of the ordinary share:

Po=(4*(1+.05))/(.19-.05)

Po=4.2/0.14

Po=$30

Test yourself:

ABC’s financial manager prepared the following information. The dividend which were paid in the current year was $5. The growth of dividends over the last 5 years were 7% and the same growth of dividends is expected to be in the future. Risk free rate is 8%, market rate is 14% and beta coefficient is 2.

Required: What is the market price of ABC’s ordinary shares?

Solution:

Firstly we need to find required return (rs) with the help of the capital asset pricing model (CAPM).

rs= Rf+(b*(rm-Rf))

rs=8+(2*(14-8))

rs=20

Next, we need to use Gordon model:

Po=D1/(rs-g)

Po=5*(1+0.07)/(0.20-0.07)

Po=5.35/0.13

Po=41.15

The price of the ABC’s ordinary share is $41.15. Note that we determined D1 (dividend within the next period) by taking known D0 (last dividend) and multiplying it by (1+ growth rate).

Gordon model (Constant-Growth Valuation Model)

The Gordon model is one of the models used in dividend valuation. It is very simple, as long as one knows the formula, which is:

P0=D1/(rs-g)

Also sometimes presented as: P = D/(k-g)

Where:

P0 or P – price of the stock

D1 or D – per share dividend expected at the end of year 1 (at the end of the next financial period)

rs or k – required return for equity investor

g – constant growth rate (expected annual growth of dividends)

Gordon model is usually used for mature companies only since it is assumed that annual growth of dividends remains constant.

It is very important to note that if you are only given the current per share dividend (D0, per share dividend received in this financial period), then you will need to adjust it for the next financial period before you can use it in the Gordon model. To do this you will need to take the current dividend and multiply it by (1 + g). The calculation is as follows:

D1=D0*(1+g)

The original equation of the Gordon model (P0=D1/(rs-g)) calculates the price of the share. However, you are looking for the cost of common stock. Therefore, you need to rearrange equation of the Gordon model as follows:

rs = (D1/Po) + g

Now you just plug in the numbers into the adjusted Gordon equation and you will be able to obtain the cost of common stock. Because common stock is paid out of the after-tax earnings, the tax adjustment is irrelevant.

Sometimes it is necessary to find the growth rate (g) first, before you can calculate the cost of the common stock (rs) with the help of the Gordon model. To do so, you need to find out what was the per share dividends applicable to common stock over the last few years (this information will be given). After obtaining this information, you can calculate the growth rate.

It is best to explain this with an example.

EXAMPLE 1:

Calculating the growth rate, which is necessary for usage of the Gordon model:

The information given below is on per share dividends applicable to common stock over the last few years. You need to find the growth rate of dividends over the given period.

Per share dividends from 2005-2010:

2010 – $4

2009 – $3.96

2008 – $3.76

2007 – $3.27

2006 – $3.25

2005 – $3

Now, by using a financial calculator, you can calculate the growth rate as follows:

PV = -3 (per share dividend in 2005, the first year from which per share dividend information is available)

FV = 4 (per share dividend in 2010, the per share dividend in the current period)

N = 5 (number of periods over which growth occurred)

Find I = it will be 5.92% (this number represents growth of dividends over the given period)

EXAMPLE 2:

Using the growth rate (found above) in the Gordon model:

Now, if we know that the growth of the dividends is expected to be the same into the future and the price of the stock is $55, we can compute the cost of common stock (rs) as follows:

rs=(4*(1+0.0592)/55)+0.0592

rs=0.0770+0.0592

rs=0.1362=0.14%

The cost of common stock also represents the return that investors expect to earn from their shares. If the actual return is less – investors will sell their stock.

Test yourself

The ordinary share is currently sold for $40 each. The growth of shares was 10% over the last 5 years and is expected to be the same in the future. A dividend of $3.5 dollars was paid to shareholders in the current period.

REQUIRED: What is the cost of an ordinary share?

SOLUTION:

We need to use the adjusted Gordon model. In other words, we need to use the formula: rs = (D1/Po) + g

Rs=(3.5*(1+.1)/40) +.1

Rs=(3.85/40) +.1

Rs=19.63%

Note that the dividend is adjusted for growth in the next period by multiplying the current dividend by (1+g).
