7.	PER SHARE INFORMATION:

Basic earnings per share is computed using the weighted average number of common shares outstanding during the period, and diluted earnings per share is computed using the weighted average number of common shares outstanding during the period adjusted for all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be antidilutive. The amounts used to compute the basic and diluted earnings per share for the three and nine months ended September 30, 2015 and 2014 are illustrated below (in thousands):

For purposes of calculating diluted earnings per share, there were no adjustments required to derive Quanta’s net income attributable to common stock. Outstanding exchangeable shares that were issued pursuant to certain of Quanta’s historical acquisitions (as further discussed in Note 9), which are exchangeable on a one-for-one basis with shares of Quanta common stock, have been included in weighted average shares outstanding for basic and diluted earnings per share for the three and nine months ended September 30, 2015 and 2014 for the portion of the respective periods that they were outstanding. However, any additional shares that may be delivered under Quanta’s accelerated share repurchase arrangement (as further described in Note 9) have not been included in the weighted average shares outstanding for basic and diluted earnings per share for the three and nine months ended September 30, 2015 because their effect would be anti-dilutive.
