Overstated No effect
Step-by-step explanation:
In case salaries are not raised at the end of 20X1, wages owed are known, an existing obligation. Current assets minus current commitments equals working capital. Working capital is exaggerated when current liabilities are overstated.
Increasing pay in 20X1, even if it had accurately been accrued, would never have been paid at the rest of 20X1. Thus, the failure to increase salaries does not affect 20X1 operating cash flow.
