Earnings (Loss) Per Common Share Table

Host Inc. Earnings (Loss) Per Common Share

Basic earnings (loss) per common share is computed by dividing net income (loss) available to common stockholders by the weighted average number of shares of Host Inc. common stock outstanding. Diluted earnings (loss) per common share is computed by dividing net income (loss) available to common stockholders, as adjusted for potentially dilutive securities, by the weighted average number of shares of Host Inc. common stock outstanding plus other potentially dilutive securities. Dilutive securities may include shares granted under comprehensive stock plans, other non-controlling interests that have the option to convert their limited partnership interests to common OP units and convertible debt securities. No effect is shown for any securities that are anti-dilutive.

(1) Represents the original issuance costs associated with the Class E preferred stock, which stock was redeemed during 2010.

(2) During 2009, we repurchased $75 million face amount of our $500 million 3 ¹/4% exchangeable senior debentures (the “2004 Debentures”) with a carrying value of $72 million for approximately $69 million. We are required to determine the dilutive effect of the repurchased 2004 Debentures separately from the 2004 Debentures outstanding at December 31, 2009. The 2004 Debentures repurchased during 2009 are treated as having been converted to Host Inc. common stock equivalents at the start of the period. Accordingly, the 2009 adjustments to net income related to the repurchased 2004 Debentures include a $3 million gain, net of interest expense on the repurchased debentures.

(3) There are 47 million, 53 million and 51 million potentially dilutive shares for our exchangeable senior debentures and shares granted under comprehensive stock plans which were not included in the computation of diluted EPS as of December 31, 2011, 2010 and 2009, respectively, because to do so would have been anti-dilutive for the period. See Note 4 “Debt” for the terms and conditions of our exchangeable senior debentures and Note 8 “Employee Stock Plans” for the terms and conditions of our comprehensive stock plans.

Earnings (Loss) Per Common Unit Table

Host L.P. Earnings (Loss) Per Common Unit

Basic earnings (loss) per common unit is computed by dividing net income (loss) available to common unitholders by the weighted average number of common units outstanding. Diluted earnings (loss) per common unit is computed by dividing net income (loss) available to common unitholders, as adjusted for potentially dilutive securities, by the weighted average number of common units outstanding plus other potentially dilutive securities. Dilutive securities may include units distributed to Host Inc. to support Host Inc. common shares granted under comprehensive stock plans, other non-controlling interests that have the option to convert their limited partnership interests to common OP units and convertible debt securities. No effect is shown for any securities that are anti-dilutive.

(3) There are 46 million, 51 million and 50 million potentially dilutive units for our exchangeable senior debentures and for units distributable to Host Inc. for Host Inc. shares granted under comprehensive stock plans which were not included in the computation of diluted earnings per unit as of December 31, 2011, 2010 and 2009, respectively, because to do so would have been anti-dilutive for the period.
