About Earnings per Share
Earnings per share (EPS) the amount of income that "belongs" to each share of common stock. An important tool for investors, EPS is often used in determining the value of a stock.
The average number of shares outstanding (the denominator of the EPS formula) is usually calculated by averaging the number of shares at the beginning of the earning period and the number of shares at the end of the period. For example, if a company earned $1 million in 2009 and had 900,000 shares at the beginning of 2009 and 1.1 million shares at the end of 2009, the 2009 EPS would be $1 million/[(.9 million shares + 1.1 million shares)/2] = $1/share.
EPS is generally reported in annualized form from the most recent fiscal year. From time to time, you will see the abbreviation (ttm) associated with earnings per share. That means that the earnings number is a sum of the previous four quarters, which is not necessarily the same as the previous fiscal year.
