Diluted Earnings per Share, or Diluted EPS, is a financial measure used to indicate a company’s performance. It reflects the earnings per share if all convertible securities were converted into common stock. The underlying idea behind Diluted EPS is to provide a conservative measure of earnings per share, under the assumption that all outstanding dilutive securities were converted into stock. Dilutive securities are any securities that can be converted into common stock.

When it comes to calculating the EPS ratio, there are two main ways to calculate it – basic EPS and Diluted EPS. Basic EPS is calculated using the number of outstanding shares of common stock. However, Diluted EPS takes into consideration not only the common shares but also any convertible securities that are convertible into common stock. This includes any convertible bonds, convertible preferred shares, stock options and warrants. Therefore, in calculating Diluted EPS, more shares are taken into consideration compared to Basic EPS.

In addition to giving investors an indication of a company’s performance, Diluted EPS is also helpful in assessing the extent to which the existing equity stake of shareholders may be diluted. If there is an increase in the number of shares due to the conversion of convertibles into common stock, then this will reduce the company’s overall earnings per share. Therefore, dilution devalues a shareholder’s existing equity stake and reduces a firm’s EPS.

It is also important to note that from an accounting point of view, Diluted EPS should generally be used over the Basic EPS ratio. This is especially the case where securities such as options and warrants are involved, since the Basic EPS ratio does not account for such securities.

Overall, Diluted EPS is a useful metric for investors to assess a company’s performance, and for companies to measure the potential effects of diluting their equity stake. By providing a conservative measure of earnings per share, Diluted EPS is also considered to be a more reliable measure compared to Basic EPS.
