The basic goal here is to test whether accruals exhibit time-series reversals (f2 < 0). An important complication arises, how- ever, from the link between accruals and subsequent sales growth. This link suggests that accruals could have a persistent component in the absence of measurement error (see also Allen et al. 2013), and the interesting question is whether accruals exhibit abnormal reversals, given the growth in sales. We address this issue in the same way described above for expenses, controlling for sales growth in the regressions.
