relatively strong growth." He also noted, "WRIT has no off balance sheet
investments or commitments for real estate, high technology or any other type of
venture. Furthermore, WRIT is not exposed to any speculative development risks."

investing in income-producing properties in the greater Washington-Baltimore
region. The Trust owns a diversified portfolio of 58 properties consisting of 10
retail centers, 23 office properties, 16 industrial and 9 multifamily

WRIT's streak of 36 consecutive years of increased earnings per share and 29
consecutive FFO per share growth spans 4 recessions. WRITS's dividends have
increased every year for 32 consecutive years. During these 32 years, WRIT's
dividends have increased 36 times, a record unmatched by any other publicly
traded real estate investment trust. WRIT shares are publicly traded on the New
