Applying "Mini Maxi Underwriting" to Securities Exams:
A corporation may need to set a minimum amount of capital to be raised during an offering to ensure that the corporation will receive enough capital from the offering to meet its goals. If a corporation needs $5 million to expand its facility it may set that as the minimum. All of the money from the sale of the securities will be held in escrow until the minimum is met.
