Basic earnings per share are calculated by dividing the net profit attributable to shareholders by the weighted average number of ordinary shares outstanding during the year.
|  | 2015 | 2014 | 
| Net result attributable to shareholders | 4,034 | 612 | 
| Weighted average number of ordinary shares | 267,886 | 203,090 | 
| Basic earnings per share (€ per share) | 15.06 | 3.01 | 
The Office Fund has no potentially dilutive ordinary shares. Therefore, the diluted earnings per share are the same as the basic earnings per share.
