The company's return on investment  ROI would be 12.5%
What does a favourable return on investment mean?
The profit from an investment is divided by the investment's cost to determine the return on investment (ROI). When represented as a percentage, an investment with a profit of $100 and a cost of $100 would have a ROI of 1, or 100%. Generally speaking, a yearly ROI of around 7% or higher is regarded as a decent ROI for an investment in stocks. This also refers to the S&P 500's average annual return when inflation is taken into account of the company to increase the profit margin.

<h3>What is ethical risk?</h3>
- In reaction to their unethical behaviors, actors end up externalizing their locus of control, as if they had no other choice.
-  In this manner, actors reduce their own power to identify a profitable alternative course of action. They reduce their freedom to choose. 
- On the other hand, inclusive awareness of ethical and unethical aspects triggers a natural search for more ethical actions (Cf. Psychological attitudes towards ethical dissonance). 
- A rational analysis of the interest of such a more ethical alternative allows avoiding exaggeration of its costs (without proper analysis, a typical justification of an unethical action is that an alternative course of action would be too costly). 
- Further, awareness of potential ethical costs increases the relative attractiveness of an alternative more ethical action. The re-framing of the situation allows the identification of new opportunities otherwise hidden to the actors.
