Answer: $9,000
Explanation:
Rule 144 is a regulation that governs the trading of restricted, unregistered, and control securities and is enforceable by the SEC.
Under the rule, the person, as an officer of the ABC Corporation is limited to selling the higher of 1% of the Outstanding stock the company has or the average weekly trading volume over the preceding 4 weeks.
1% of the outstanding 900,000 shares is;
= 1% * 900,000
= 9,000 shares
This is higher than the average weekly trading volume over the preceding 4 weeks so this is the maximum permitted sales figure.
