[1] Income (Loss) allocated to noncontrolling interest in Hersha Hospitality Limited Partnership (the “Operating Partnership” or “HHLP”) has been excluded from the numerator and the Class A common shares issuable upon any redemption of the Operating Partnership’s common units of limited partnership interest (“Common Units”) and the Operating Partnership’s vested LTIP units (“Vested LTIP Units”) have been omitted from the denominator for the purpose of computing diluted earnings per share because the effect of including these shares and units 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.
