The study looked at how cash flow affects accruals in financial reporting. By considering cash flow changes, the researchers found a negative relationship with accruals, especially when cash flow changes are not consistent. They also found that the length of a company's operating cycle influences the relationship between accruals and revenue changes. Including these factors in accrual models improved their accuracy and helped identify potential earnings manipulation. This means that understanding cash flow dynamics is crucial for predicting accruals accurately.
