Adopts New Dividend Policy

Chicago, IL – December 9, 2010 — Equity Residential (NYSE: EQR) today announced that on December 8th its Board of Trustees declared dividends on its common and preferred shares. A common share dividend for the fourth quarter of $0.4575 per share will be paid on January 14, 2011 to shareholders of record on December 20, 2010. This dividend will bring the total paid for the year to $1.47 per share, a 9% increase over the company’s previous annualized dividend of $1.35 per share.

For 2011, the company intends to pay a dividend equal to approximately 65% of FFO for the year as adjusted for certain non-comparable items. As in 2010, the company intends to pay $0.3375 per share for each of the first three quarters of the year. For the fourth quarter, the company intends to pay a dividend that will bring the total payment for the year to approximately 65% of FFO as adjusted for certain non-comparable items.
