(a) Advantages
A stock market quotation might have the following advantages:
(i) Access to outside finance. It provides the opportunity to raise equity finance from other than existing shareholders. It should also be easier to raise additional debt finance.
(ii) Once well-established, a company via a better credit rating can obtain cheaper debt finance.
(iii) Marketability of shares. Existing shareholders are given the opportunity to sell their shares more easily and at better prices.
(iv) Incentive schemes including share ownership can be offered to management and employees.
(v) Status of company. A publicly quoted company may achieve greater status than a similar unlisted company: this could improve staff morale and result in increased publicity and sales.
(vi) Take-overs. Other businesses can be acquired by using shares as consideration rather than having to use cash.

Disadvantages
A stock market quotation has the following disadvantages:
(i) Costs. It is expensive e.g., in terms of advisers and advertising, to achieve a listing plus routine costs of conforming to requirements of the Stock Exchange.
(ii) Accountability. It makes it necessary for the board to report to ‘outside shareholders’; this would be particularly important, for example, in the case of a family-owned company where most shareholders are board members.
(iii) Dilution of control of existing shareholders.
(iv) Take-overs. With shares in the hands of the public, risk of take-over may be increased.

(b) Types of Issue Costs
The types of issue costs associated with obtaining a stock exchange listing include:

• Costs of advisers, such as financial consultants and legal experts.
• Advertising costs to promote the listing.
• Routine costs of conforming to Stock Exchange requirements, such as regulatory and compliance expenses.
• Other administrative costs related to the listing process, such as documentation and filing fees.
