Final answer:
The operating profit margin includes the cost of goods sold, so the statement is false. This margin assesses the percentage of sales remaining after deducting COGS and all operating expenses.
Step-by-step explanation:
The statement is false. The operating profit margin is indeed impacted by sales and operating expenses, but it also includes the cost of goods sold (COGS). The formula for operating profit margin is Operating Profit divided by Net Sales, where Operating Profit equals Net Sales minus COGS and all other operating expenses. Therefore, the operating profit margin is a measure of the percentage of each sales dollar remaining after all costs and expenses, including the cost of goods sold, are deducted.
