3.	Earnings Per Common Share (Unit)

Basic earnings per common share (unit) is computed by dividing net income attributable to common stockholders (unitholders) by the weighted average number of shares of Host Inc. common stock or Host L.P. common units outstanding. Diluted earnings per common share (unit) is computed by dividing net income attributable to common stockholders (unitholders), as adjusted for potentially dilutive securities, by the weighted average number of shares of Host Inc. common stock or Host L.P. common units outstanding plus other potentially dilutive securities. Dilutive securities may include shares granted under comprehensive stock plans or the common OP units distributed to Host Inc. to support such shares granted, and other non-controlling interests that have the option to convert their limited partnership interests to common OP units. No effect is shown for any securities that are anti-dilutive. We have 7.9 million common OP units which are convertible into 8.1 million common shares that are not included in Host Inc.’s calculation of earnings per share as their effect is not dilutive. The calculation of Host Inc. basic and diluted earnings per common share is shown below (in millions, except per share amounts):
