Decision makers and analysts look deeply into profitability ratios to identify trends in a companys profitability. Profitability ratios give insights into both the survivability of a company and the benefits that shareholders receive. Identify which of the following statements are true about profitability ratios. Check all that apply.

A higher operating margin than the industry average indicates either lower operating costs, higher product pricing, or both.

If a companys operating margin increases but its profit margin decreases, it could mean that the company paid more in interest or taxes.

An increase in the return on assets ratio implies an increase in the assets a firm owns.

If a company issues new common shares but its net income does not increase, return on common equity will increase.
