Abstract
The main purpose of this research is to
investigate the information quality of
preliminary (un-audited) earnings. The
research questions are as follows: (1) Is the
mandatory preliminary earnings
announcement (hereafter MPEA )
optimistically reported? (2) What are the
determinants of the accuracy of MPEA? (3)
What is the effect of MPEA disclosure
regulation on the accuracy of preliminary
earnings estimates.
Research sample for question (1) and (2)
contains the companies required to disclosure
MPEA for any year of 2001 or 2002.
Research sample for question (3) contains the
above companies and the voluntary
un-audited earnings disclosure for any year
from 1997 to 2000.
Both univariate tests and multiple OLS
regression analyses are used to examine the
relationship between accuracy of MPEA and its determinants. The univariate results
indicate that the companies, on average, tend
to release optimistic MPEA. After controlling
for other factors, we find that the MPEA is
more accurate for firms with good news or
more insider shareholdings. The accuracy of
preliminary earnings estimate is not affected
by MPEA disclosure regulation significantly.
