| Note | 28 - Earnings per share |
Basic and diluted earnings per share were computed as shown in the table below for the periods indicated. Basic earnings per share are computed by dividing the net income attributable to the stockholder of ITAÚ UNIBANCO HOLDING by the average number of shares for the period, and by excluding the number of shares purchased and held as treasury shares by the company. Diluted earnings per share are computed on a similar way, but with the adjustment made in the denominator when assuming the conversion of all shares that may be diluted.
