[1] Income (loss) allocated to noncontrolling interest in HHLP has been excluded from the numerator and units of limited partnership interest in HHLP have been omitted from the denominator for the purpose of computing diluted earnings per share since the effect of including these amounts in the numerator and denominator would have no impact.  In addition, potentially dilutive common shares, if any, have been excluded from the denominator if they are anti-dilutive to income (loss) from continuing operations applicable to common shareholders.
