Final answer:
The standard voting threshold for shareholder votes is generally a majority rule, over 50%. At Darkroom Windowshade Company, investors 1 and 2 cannot dictate company direction alone since they don't reach the 50,001-share majority threshold. Supermajority rules would necessitate an even higher percentage of votes for change.
Step-by-step explanation:
The standard voting threshold for shareholder votes is typically a majority rule, meaning more than 50% of the votes must be in favor of a proposal for it to pass. In the context of the Darkroom Windowshade Company with 100,000 shares outstanding, a minimum of 50,001 shares would need to vote in the same way to meet this threshold and change the company's top management. If investors 1 and 2, who together control 38,000 shares, vote together, they do not reach the majority threshold on their own and thus cannot be certain of always getting their way.
However, the establishment of a supermajority rule would require a higher percentage of votes, often 60%, two-thirds, or even three-fourths of the votes cast. Therefore, to determine the minimum number of investors required to change management, one must consider the specific voting rules that the Darkroom Windowshade Company has established. If a simple majority is all that is required, then investors holding more than 50% of the shares would be needed. If a supermajority rule exists, even more votes would be necessary to enact change.
