The important information contained in the prospectus includes fund investment objectives, investment scope, investment strategy, performance comparison benchmark, risk-return characteristics, investment restrictions and so on.

The calculation method included in the prospectus: individual open-end fund varieties, such as ETF, can be listed and traded on the exchange or purchased and redeemed by portfolio securities in the primary market; In the operation of open-end funds, some cash should be reserved for redemption, while the liquidity requirement of closed-end fund portfolio operation will be lower, so the risk-return characteristics of the two types of funds are inevitably different.

The management fees and custody fees of different fund types are different. Even for the same type of funds, the way to extract management fees may be different. For example, some managers collect management fees daily, and some managers will stipulate in the prospectus that if the net asset value of the fund is lower than a certain standard, they will stop collecting management fees; For some special types of funds, such as money market funds, not only management fees and custody fees are accrued.

Announcement method of prospectus: the prospectus is one of the most basic and important documents for investors to understand the investment, and it is a must-read document before investing. Because the subscription of open-end funds is a continuous process, many factors related to funds may change during this process, so the prospectus (prospectus) must be updated regularly. Usually, it will be updated every six months from the effective date of the fund contract, and it will be announced within 45 days after the end of six months, and the updated content will expire on the last day of six months.
