| 1 | The weighted average number of shares outstanding in 2016 and 2015 reflects the shares issued as a result of the capitalization of retained earnings declared on March 2016 and March 2015, as applicable (note 20.1). |
| 2 | According to resolution of the Parent Company’s stockholders’ meeting on March 30, 2017. |
| 3 | The number of CPOs to be issued under the executive share-based compensation programs, as well as the total amount of CPOs committed for issuance in the future under the mandatorily and optionally convertible securities, are computed from the beginning of the reporting period. The number of shares resulting from the executives’ stock option programs is determined under the inverse treasury method. |
| 4 | For 2017, 2016 and 2015, the effects on the denominator and numerator of potential dilutive shares generate antidilution; therefore, there is no change between the reported basic earnings per share and diluted earnings per share. |
