Relevance of goodwill impairments to cash flow prediction and forecasting

Abstract

This study examines the contribution of goodwill impairment information to the prediction and forecasting of future operating cash flows. Extending the framework of Barth, Cram, and Nelson, we find that explicitly including goodwill impairments incrementally improves 1-year-ahead cash flow prediction and forecasting. Improved cash flow forecasting is present over the entire 2001-2009 study period as well as for each year within the study window. In addition, goodwill impairments retain their significance and predictive power when other non-recurring charges (e.g., restructuring, asset write-downs, and merger and acquisition costs) are added to the model, both individually and aggregately, and when market-related information (i.e., change in market capitalization) is included in the model. While these findings are validated by in-sample prediction techniques, this study is also one of only a few studies to investigate the incremental, out-of-sample predictive power of non-current accruals on reported (as opposed to computed) operating cash flows. Analysts, investors, creditors, and others interested in future cash flows should separately consider goodwill impairment information, when available, to improve the accuracy of cash flow prediction and forecasting.
