He declined to say what business activities these companies engaged in.

Any company that has market power can engage in price discrimination.

Companies with cash will sit on it, do nothing and simply engage in survival.

This was not the first time the company had engaged in clumsy public relations.

The company also engages with its customers actively through social media.

So the question is not why some companies engage in fraud or deception.

Later, the company engaged in toy manufacturing and movie distribution.

Those companies can engage in no other activities and are subject to strict supervision by a government agency.

But the company also engaged in legitimate computer sales, giving it plausible cover.

This company engaged in construction operations and focused on residential building.
