This study investigates the aptitudes of the cash-based and accrual-based accounting data for predicting future cash flows from operations in the French context. In addition, our paper aims to investigate the effect of the economic crisis on the prediction of future cash flow. The sample consists of 61 non-financial French listed companies, using annual data over the period 1999–2016. The study found that, regardless of the period, the model based on the operating cash flows combined with disaggregate accruals has a stronger explanatory power for predicting future operating cash flows, compared to both earnings and operating cash flows combined with the aggregate accruals models. Moreover, our results show that the aggregation of earnings falsifies the contribution of each accrual item and, as a result, the decomposition of earnings into cash flows and disaggregate accrual enables a much more accurate explanation of future operating cash flows.
