Under normal circumstances, each fund management company will stipulate the conversion rate between its funds, and the conversion rate between different types of funds is often different. If investors want to convert 10000 copies of Fund A into Fund B, they can directly convert Fund A into Fund B by using the fund conversion business. Under different rate settings, investors finally get the calculation formula of fund B's share: direct conversion case 1 (the fund company directly sets the conversion rate between the two funds. Suppose a fund company sets the conversion rate of its fund A to fund B as R, and the unit net values of funds A and B on T day are Va and Vb respectively. Then on T+ 1 day, investors will get the share of fund b: the number of shares of fund b =10000 * va * (1-r)/the handling fee charged by VB fund company =10000 * va * r. 2 (The fund company has no direct conversion. The subscription rates of funds A and B are Ba and Bb respectively, so on T+ 1 day, investors will get the share of fund B as follows: when Bb & gtBa, the share number of fund B =10000 * VA * (1-SA)/[(1+). When bb < =ba, the number of shares of fund B =10000 * va * (1-sa)/VB; The handling fee charged by the fund company is: when Bb & gtBa, the handling fee charged by the company =10000 * va * s+10000 * va * (1-sa)/[(1+bb-ba) * VB]. = 10000 * Va *(Sa+b b-Ba)/( 1+b b-Ba)； When bb < =ba, the handling fee charged by the company =10000 * va * sa; Below, we will take China Merchants Fund Company, the earliest fund conversion company in China, as an example to illustrate the related expenses of the company's fund conversion business. According to the announcement of China Merchants Fund Company, the company's fund conversion business conforms to the "direct conversion situation II" introduced in the previous section. For example, the mutual conversion between China Merchants Core Value Fund and China Merchants Aberdeen Fund is known: the scale of investors' assets is below 6,543,800,000 assets; The investor's holding time is less than 1 year; Subscription rate of China Merchants Core Value Fund =1.5%; Maximum redemption rate = 0.5%; Subscription rate of China Merchants Anben Fund = 0; Maximum redemption rate =0. 1 Conversion of China Merchants' Core Value Fund into China Merchants' Aberdeen Zengli Fund Investor A converted 10000 copies of China Merchants' Core Value Fund into China Merchants' Aberdeen Zengli Fund on March 22nd, 20 10/.0427 yuan, and the unit net value of China Merchants' Aberdeen Zengli Fund was/kl. Then, on 23rd, the number of shares obtained by investor A in China Merchants Ampen Fund is:10000 *1.0427 (1-0.5%)/1.2515 = 8289.94 (copies) The handling fee charged by the fund company is: 65438. 0.5%=52. 135 (yuan) 2 China Merchants Aberdeen Profit-increasing Fund is converted into China Merchants Core Value Fund. Investor B converted 10000 copies of China Merchants' Aberdeen Profit-increasing Fund into China Merchants' Core Value Fund at RMB 20 1.0427 on March 22nd. Then, on 23rd, the number of shares of China Merchants Core Value Fund obtained by investor B is10000 *1.2515 * (1-0)/[(1+1.5%).
