[1] Cumulative quarterly per share performance may not equal annual per share totals due to the effects of the amount and timing of capital increases. When computing earnings per share for an interim period, the denominator is based on the weighted-average shares outstanding during the interim period, and not on an annualized weighted-average basis. Accordingly, the sum of the quarters' earnings per share data will not necessarily equal the year to date earnings per share data.
