Aethertek Technology Co  (ROCO:3219) Pretax Margin % Explanation

The pretax margin, as know as pretax profit margin, is widely used to measure the operating efficiency of a company before deducting taxes.

The pretax margin is sometimes preferred over the net margin as tax expenditures can make profitability comparisons between companies misleading.

It is a useful tool to compare companies operating in the same sector and less effective when comparing companies from other sectors as each industry generally has different operating expenses and sales patterns.

The long term trend of the pretax margin is a good indicator of the competitiveness and health of the business.
