Fund, broadly speaking, refers to a certain amount of funds set up for a certain purpose. It mainly includes trust and investment funds, provident funds, insurance funds, retirement funds and funds of various foundations. From the accounting point of view, capital is a narrow concept, which refers to funds with specific purposes and uses. The fund we are talking about mainly refers to the securities investment fund. According to whether fund units can be increased or redeemed, they can be divided into open-end funds and closed-end funds. Open-end funds are not traded on the market (as the case may be), but are purchased and redeemed by banks, brokers and fund companies, and the fund scale is not fixed; Closed-end funds have a fixed duration and are generally listed and traded on the stock exchange. Investors buy and sell fund shares through the secondary market. Unit Trust is a management company established by a document named trust deed. In terms of organizational structure, it has no board of directors. The fund manager company sets up the fund itself as the entrusting company, and employs the manager to manage the operation and operation of the fund by himself or again. Usually, securities companies or underwriting companies are responsible for the issuance, trading, transfer, trading, profit distribution, income and debt service of beneficiary certificates.

The trustee accepts the entrustment of the fund manager company to register and open an account for the fund in the name of the trustee or trust company. The fund account is completely independent of the account of the fund custody company. Even if the fund custody company goes bankrupt due to poor management, its creditors cannot use the assets of the fund. Its duties are to manage, keep and dispose of the trust property, supervise the investment work of the fund manager, and ensure that the fund manager abides by the investment regulations listed in the prospectus, so as to make its investment portfolio meet the requirements of trust deed. When there is a problem with the unit trust fund, the client is responsible for claiming compensation from the investor. Balanced fund refers to a fund whose investment goal is not only to obtain the current income, but also to pursue the long-term appreciation of the fund assets, and to disperse the funds into stocks and bonds to ensure the safety and profitability of the funds.
