        EPS is computed by dividing net income by the weighted
        average number of common shares outstanding for the period.
        Diluted EPS is computed by dividing net income by the
        weighted average number of common shares outstanding during
        the period after giving effect to all dilutive potential
        common shares that were outstanding during the period.
        Dilutive potential common shares consist of the incremental
        common shares issuable upon the exercise of stock options
        and warrants and unvested shares granted to employees and
        directors.
