Listed companies in the stock market can invest part of their shares in the stock market itself. Companies can buy the same company shares or buy shares for other listed companies. As part of the regulations, companies should report periodically to securities commission their investment policy that includes their intend to invest in the market, and the purpose of the investment (long term or short term).
After each investment transaction, companies should report to the securities commission the transaction details. There are huge burden on the commission staff to ensure the compliance between the investment policies and the actual investment transactions done by companies. The investment transparency system helps the commission staff to easily verify companies investments (and subsidiaries investments) in the capital market and that all investment transactions are performed according to the disclosed investment policy.
