Corporate Disclosure System refers to the system that requires listed corporations to make public corporate information and business details, which could be influential to investment decisions on stock prices, thus helping the investors to make informed decisions. The disclosure system settles information asymmetry inside the KRX markets, enhances fair securities trading and protects investors.

In order to be effective, the disclosure must meet the following requisites

Timeliness of information

To prevent flawed investment decisions, the latest business details of listed corporations must be made public. Outdated business details often trigger the spread of rumors, which cause the distortion of stock prices and unforeseen losses to investors.

Accuracy of information

False, incomplete or vague information causes confusion and mistaken investment decisions. Therefore, it is essential to disclose accurate and complete information, i.e., including both favorable and unfavorable facts, and not to omit any significant details.

Usability of information

The disclosed information must be easily comprehensible and usable. Therefore, the information should be clearly stated, using language that is understandable to all investors and to members of the general public, who may not have professional knowledge in finance or securities matters. In particular, to cover the diversity of investors participating in the stock market, listed corporations should use plain expressions rather than professional terms regarding their duties so that investors may easily understand their information. In turn, this ensures the practical balance of information communication.

Accessibility of information

Since the main purpose of the disclosure system is to remove asymmetric information, the disclosed information must be accessible to all existing and potential investors equally. In order to accomplish this, business information should be made available to every investor at the time of disclosure by using an information communication medium to ensure balance. This would ensure fair trading and facilitate perfect competition in the stock market.
For this purpose, the Stock Market Division operates KIND (Korea Investor’s Network for Disclosure) System, which investors can access from anywhere and at anytime. This system has vastly improved the fairness of information asymmetry. (http://kind.krx.co.kr)
