The equity positions of various individuals and entities that contributed their properties to the Operating Partnership in exchange for OP Units are collectively referred to as the “Minority Interests – Operating Partnership”. Subject to certain restrictions, the Minority Interests – Operating Partnership may exchange their OP Units for EQR Common Shares on a one-for-one basis.

Net proceeds from the Company’s Common Share and Preferred Share (see definition below) offerings are contributed by the Company to the Operating Partnership. In return for those contributions, EQR receives a number of OP Units in the Operating Partnership equal to the number of Common Shares it has issued in the equity offering (or in the case of a preferred equity offering, a number of preference units in the Operating Partnership equal in number and having the same terms as the Preferred Shares issued in the equity offering). As a result, the net offering proceeds from Common Shares and Preferred Shares are allocated between shareholders’ equity and Minority Interests – Operating Partnership to account for the change in their respective percentage ownership of the underlying equity of the Operating Partnership.

The Company’s declaration of trust authorizes the Company to issue up to 100,000,000 preferred shares of beneficial interest, $0.01 par value per share (the “Preferred Shares”), with specific rights, preferences and other attributes as the Board of Trustees may determine, which may include preferences, powers and rights that are senior to the rights of holders of the Company’s Common Shares.

The following table presents the Company’s issued and outstanding Preferred Shares as of December 31, 2007 and 2006:
