NOTE: Quarterly and year-to-date computations of per share amounts are made independently. Therefore, the sum of per share amounts for the quarters may not agree with the per share amounts for the year. Computations of per share amounts from continuing operations, discontinued operations and net income (loss) are made independently. Therefore, the sum of per share amounts from continuing operations and discontinued operations may not agree with the per share amounts from net income (loss) available to common stockholders.
