Companies may issue common or preferred stock to generate cash flow. However, sometimes companies will buy back stock that was issued to shareholders. Discuss at least one reason why a company would buy back its own stock and provide an example to support your points. In addition, discuss any potential negative effects of the stock repurchase. Participate in follow-up discussion by changing the fact patterns provided by classmates to show when/why a company may want to reissue its treasury stock. Provide an example to support your points solved with reference and citations from 2019.
