The _________ may indicate that the firm is experiencing stockouts and lost sales.

The Inventory Turnover Ratio indicates whether a firm is experiencing stockouts and lost sales.

The Inventory Turnover Ratio is calculated as:

$\text{Inventory Turnover Ratio} = \frac{\text{Cost of Goods Sold}}{\text{Average Inventory}}$

When this ratio is abnormally high, it suggests that inventory is being sold extremely quickly relative to the stock maintained. This indicates the firm may be:

• Keeping very low inventory levels
• Running out of stock frequently (stockouts)
• Unable to meet customer demand immediately

Such stockouts result in lost sales opportunities because customers cannot purchase products that are unavailable. While a high inventory turnover is generally favorable (indicating efficient inventory management), an excessively high ratio signals that the firm needs to increase its inventory levels to avoid losing potential revenue.

The other options measure different aspects:

• Average payment period tracks how long the firm takes to pay creditors
• Average collection period measures the time to collect from debtors
• Quick ratio assesses short-term liquidity

None of these relate to inventory availability or stockout situations.
