Earnings (Loss) Per Share

On January 31, 2017 our common stock was reclassified into shares of Class B common stock and, on February 6, 2017, we completed our IPO of Class A common stock. Other than voting rights, the Class B common stock has the same rights as the Class A common stock and therefore both are treated as the same class of stock for purposes of the earnings per share calculation. Laureate computes basic earnings per share (EPS) by dividing income available to common shareholders by the weighted average number of common shares outstanding for the reporting period. Diluted EPS reflects the potential dilution that would occur if share-based compensation awards or contingently issuable shares were exercised or converted into common stock. To calculate the diluted EPS, the basic weighted average number of shares is increased by the dilutive effect of stock options, restricted stock, and other share-based compensation arrangements determined using the treasury stock method.

The following tables summarize the computations of basic and diluted earnings per share:

The shares of Class A common stock that will be issued upon completion of the conversion of the Series A Preferred Stock are not included in the calculation of diluted EPS as the effect would have been antidilutive. The following table summarizes the number of stock options and shares of restricted stock that were excluded from the diluted EPS calculations because the effect would have been antidilutive:



For the three months ended March 31,	2018	2017
Stock options	9,840	12,296
