A company’s diluted earnings per share (EPS) are measured using these stock equivalents. Investors can assess the possible dilution effect on existing owners and make better investment choices by evaluating common stock equivalents. Examples include preferred stock, stock options, warrants, grants bonds, and other shares with convertible options for common stocks.

Key Takeaways

  • Common stock equivalents are instruments that can be converted into or possess properties similar to common stock.
  • The security can be converted into common stocks when the market price reaches or crosses the exercise price. If the asset is traded below the mentioned market price, money would be lost in conversion, and hence, such securities will not be termed as equivalents.
  • They aid in understanding the possible dilution effect on earnings per share, as well as appraising a company’s financial performance strength by taking into account the prospective impact of these securities on future earnings and stock prices.

Common Stock Equivalent Explained 

Common stock equivalent refers to securities that allow holders to acquire common stock when the security’s market price is above the exercise price. In other words, security is defined as a stock equivalent when its market price per share exceeds its conversion price, and it trades as an equity issue, moving in along with the common stock price.

The stock equivalents are important in financial reporting and analysis because they can change a company’s earnings per share estimates and dilute existing shareholders’ stakes in the company when converted to common stock. This is considered when computing diluted earnings per share (diluted EPS), as it represents the possible fall in profits per share if all common stock equivalents are converted.

These stock equivalents are divided into convertible securities and employee stock option plans. Convertible securities consist of preferred stock and bonds with conversion features. Employee stock option plans provide restricted and unrestricted stock options, grants, and warrants. These arrangements allow employees to buy shares at a discount or for free. If the securities are dilutive, they are classed as common stock equivalents and utilized to calculate primary earnings per share. Some instruments, such as convertible bonds, can be anti-dilutive, boosting earnings per share.

How To Convert?

Depending on their type, stock equivalents are normally converted or exercised when a market-determined exercise price is met or exceeded. The terms are usually set when the security is issued. As long as the market price is satisfied, the security is comparable to common stock and can be convertible without incurring a loss.

Employee stock option schemes, which allow employees to obtain options or warrants or buy securities at a discount, can be used to introduce common stock equivalents. These options can be utilized after a set vesting period, which is normally one year. Some limitations may need another full year before an employee can sell the stocks. Other common stock counterparts, such as bonds converted into shares, have their laws limiting when and how they can be exchanged. These provisions may provide the corporation greater time to accumulate assets using the funds used to purchase such securities before converting them into ordinary stock.


Let us look into a few examples to understand the concept better.

Example #1

Suppose ABC Ltd is a well-known cloth manufacturing company. The company recently issued convertible bonds to raise capital for its upcoming venture. The business also plans to venture out into different countries and age groups. Let’s say an investor, Dan, after being impressed by the company’s prospects, wants to help the business grow and decides to buy 100 convertible bonds. Suppose each convertible bond can be converted into 50 shares of common stock, and he decides to convert them later. At the point of conversion, he would receive 5000 shares of common stock in exchange.

Example #2

Check out this paper, which discusses whether common stock equivalents should be included in the calculation of EPS and equity market value.

The study examines when the stock market participants incorporate price per share the potential dilution due to the common stock equivalent. It states that the participants tend to calculate the market value of equity by multiplying the number of outstanding shares and the price per share. It concludes by stating that firms with high levels of dilution use diluted EPS, and a number of shares are to be used.
