In order to ensure the smooth implementation of the new accounting standards for business enterprises by securities investment funds (referred to as funds), China Securities Regulatory Commission has successively issued two documents, namely, Notice on the Convergence of the Implementation of Accounting Standards for Business Enterprises by Securities Investment Funds and Notice on the Valuation Business and Net Share Value of Securities Investment Funds. According to the recent market changes and the problems existing in the determination and measurement of fair value in the implementation of new accounting standards by fund management companies, China Securities Regulatory Commission further standardized the fund valuation business, especially the valuation of non-market investment products such as long-term suspended stocks, and formulated the Guiding Opinions on Further Standardizing the Valuation Business of Securities Investment Funds.
