Building on the Dechow et al. (1998) model of the accrual process, this stu
dy investigates the role of accruals in predicting future cash flows. The m
odel shows that each accrual component reflects different information relat
ing to future cash flows; aggregate earnings masks this information. As pre
dicted, disaggregating accruals into major components-change in accounts re
ceivable, change in accounts payable, change in inventory, depreciation, am
ortization, and other accruals-significantly enhances predictive ability. E
ach accrual component, including depreciation and amortization, is signific
ant with the predicted sign in predicting future cash flows, incremental to
current cash flow. The cash flow and accrual components of current earning
s have substantially more predictive ability for future cash flows than sev
eral lags of aggregate earnings. The inferences are robust to alternative s
pecifications, including controlling for operating cash cycle and industry
membership.
