REITs pay dividends in order to retain their favorable tax status. As the next chapter on stock explains, corporate dividends are made from earnings. REIT dividends often are not made from earnings but the distributions are made from funds from operations

(FFO). REIT accounting earnings are adjusted for noncash expenses such as depreciation to determine funds from operations. In addition, a REIT may sell a property and distribute the proceeds. For these reasons, financial analysts often use FFO instead of earnings to analyze a REIT. Distributions are often more highly correlated with pershare funds from operation than they are with earnings per share (EPS). Consider the following FFO and EPS for Washington Real Estate Trust:

Year Distributions FFO EPS 1999 $1.16 $1.57 $1.24 2000 1.23 1.79 1.26 2001 1.31 1.96 1.38 2002 1.39 1.97 1.32 2003 1.47 2.04 1.13 2004 1.55 2.05 1.09 2005 1.60 2.07 1.84 2006 1.64 2.12 0.88 2007 1.68 2.31 1.34 2008 1.72 2.12 0.67 To verify that the dividend distribution is more strongly correlated with FFO than with EPS, compute the correlation coefficients relating the distributions to FFO and to EPS.
