Previous studies (Carslaw, 1988;Thomas, 1989;Niskanen & Keloharju, 2000) have shown that companies' managers tend to round-up the ®rst digits of reported earnings (i.e. for companies reporting pro®ts). According to Carslaw (1988), this type of behaviour is inspired by the existence of the so-called`$1Á99' phenomenon where a price of $1Á99 is perceived as being abnormally lower than one of $2Á00. In the current study, we try to determine whether managers of UK-listed companies also engage in this type of`earnings rounding-up behaviour'. Analogous to the earlier studies, our study compares observed and expected frequencies for the second-from-the-left digit in reported earnings. Our results suggest that managers of UK-listed companies tend to round-up reported pre-tax income, in a way that increases the ®rst digit by one, when they are faced with a nine in the second-from-the-left position for this particular earnings measure. The major contribution of the current study is that it introduces discretionary accruals in this line of research. Discretionary accruals were estimated using both the Jones model (1991) and the modi®ed Jones model as proposed by Dechow et al. (1995). Our results clearly suggest that discretionary accruals are used in order to round-up reported earnings ®gures. Moreover, discretionary accruals enabled us to increase the power of the tests used in previous studies.
