Final answer:
The power of a shareholder to change a company's operations depends on their share of ownership. With $100,000 in common stock in Bombardier, influence is limited; $100 million offers greater clout. In the case of the Darkroom Windowshade Company, at least three major investors would need to cooperate to change top management.
Step-by-step explanation:
When shareholders are unhappy with how a firm is operated, they have the option to exercise their power to try and instigate change. As a shareholder of Bombardier, if you dislike the firm's operations, your course of action may depend on the amount of stock you own. Owning $100,000 worth of stock may not give you significant influence, whereas owning $100 million could provide you with substantial power and perhaps a seat on the board to directly influence management decisions.
Looking at a hypothetical case like the Darkroom Windowshade Company, no single investor holds a majority. In this company, to change top management, over 50% of the voting power is required, i.e., ownership of more than 50,000 shares. The minimum number of investors necessary to achieve this would depend on the distribution of shares among them. For instance, investors 1 and 2 together have 38,000 shares, which is not enough to guarantee control. They would need support from at least investor 3 to surpass the 50% threshold. Thus, in a simplified model, it would take a coalition of at least 3 investors to effect change.
