Badwill

What Does Badwill Mean?
The negative effect felt by a company when shareholders and the investment community find out that is has done something that is not in accordance with good business practices. Although typically not expressed in a dollar amount, badwill can play out in the form of decreased revenue, loss of clients or suppliers, loss of market share and federal indictments for any crimes committed. 

Investopedia explains Badwill
There are several cases in which badwill caused a severe downturn in company stock, such as Tyco, Adelphia, Martha Stewart, Enron and Worldcom. In each new bull market, we are likely to see the same offenses committed by new people. This phenomenon has caused a rise in "socially conscious" investing, where companies promoting badwill are excluded as a matter of policy.
