Where an issuer, which had originally qualified for a listing of its equity securities under Chapter 2, intends to set up an investment fund or undertake any business(es) in investment fund management, which in aggregate, exceeds 50% of the issuer's net asset value, the issuer must demonstrate to the Exchange that it satisfies the listing requirements for investment funds stipulated in Chapter 4 before it takes any steps to undertake such a business, whether through a transaction or a series of transactions.
