Final answer:
A round lot on NASDAQ Level 2 is 100 shares. To change the management of The Darkroom Windowshade Company, a minimum of three investors is required to surpass the majority share threshold, and Investors 1 and 2 cannot always control the company by themselves.
Step-by-step explanation:
The question regarding the NASDAQ Level 2 minimum size pertains to the minimum number of shares that can be displayed on the Level 2 quotation system. The correct answer is: A) 100 shares. A round lot is traditionally considered to be 100 shares of stock, and this is the minimum size for a Level 2 quote.
For the problem concerning The Darkroom Windowshade Company, changing the company's top management would require a majority vote. To determine the minimum number of investors needed to achieve this, we need to find a combination of investors whose total number of shares exceeds 50,000, as this would represent a majority of the 100,000 outstanding shares. Investor 1 with 20,000 shares and Investor 2 with 18,000 shares together hold 38,000 shares. Adding Investor 3 with 15,000 shares to this coalition gives us 53,000 shares, surpassing the 50% threshold. So, at least three investors would be necessary to change the company's top management. However, Investors 1 and 2 alone do not hold a majority and thus cannot be certain of always getting their way in how the company is run.
