[1] Income (loss) allocated to noncontrolling interest in HHLP has been excluded from the numerator and Common Units and Vested LTIP Units have been omitted from the denominator for the purpose of computing diluted earnings per share since 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) applicable to common shareholders.
