Notes:
PDR is defined as the cum-dividend day closing price minus
the ex-dividend day closing price (adjusted by the expected
daily return) divided by the dividend amount. The expected
daily return is estimated using the market model with
estimation period [-45, -6] and [6, 45]. The market return
is defined as the return of the value-weighted market
portfolio including distributions. The mean has been
corrected for two sources of heteroskedasticity: the
security's variance and the dividend yield effect. Data
are winsorized at [2.5%, 97.5%]. The sample includes
taxable dividend payments (distribution codes 1222, 1232,
1242, and 1252) of common stocks (share codes 10-12) in
2001 (excluding January), 2002, 2004, and 2005. Pre-Act
period is from February 1, 2001 to December 31, 2002;
Post-Act period is from January 1, 2004 to December 31,
2005. Wilcoxon sign test p-values are reported for
testing the median equal to one and t-statistics are
reported for testing the mean equal to one. In Panel B,
Wilcoxon-Mann-Whitney test two side p-values are reported
for testing the difference in the medians equal to zero
and t-statistics are reported for testing the difference
in the means equal to zero.
*, and *** indicate statistical significance at the 10%,
5%, and 1%, levels, respectively.

Notes:
The excess return is the return above that predicted
by the market model. The market return is defined as
the return of the value-weighted portfolio including
distributions. The estimation period for the market
model is [115, -0] and [6, 45]. Weighted least squares
are used to calculate the average excess return with
the inverse of the standard deviation of the estimation
period return as the weight. Excess returns in the
11-day event window [-5, +5] are presented (ex-dividend
day = 0). T-statistics are for testing the null hypothesis
that mean excess return is zero. Pre-Act period is from
February 1, 2001 to December 31, 2002; Post-Act period
is from January 1, 2004 to December 31, 2005.

Notes:
We test the change in dividend clienteles. The dependent
variable of regressions in Panel A is the PDR. Weighted
least squares are utilized to correct for heteroskedasti-
city with the ratio of squared dividend yield to the
stock's variance as the weight. The dependent variable
of regressions in Panel B is the ex-dividend day excess
returns. Weighted least squares are used to calculate
the average excess return with the inverse of the
standard deviation of the estimation period return as
the weight. Data are winsorized at [2.5%, 97.5%].
T-statistics are in parentheses under the parameter
estimates. Dividend yield is calculated by dividing
the dividend amount by the cum-dividend day closing
price. Risk is measured by the variance of the security's
return scaled by the variance of the market returns during
the estimation period [-25, -0] and [6, 25]. Market cap is
the natural logarithm of the market capitalization on the
cum-dividend day (i.e., cum-dividend day price multiplied
by the outstanding shares). Pre-Act period is from February
1, 2001 to December 31, 2002; Post-Act period is from
January 1, 2004 to December 31, 2005. PostDum = 0 for
pre-Act period, and 1 otherwise.
*, **, and *** indicate statistical significance at the
10%, 5%, and 1 levels, respectively.
