Dilution cost is to average investment and spread risks. Funds are invested on schedule at different time points, and the input cost is relatively average, which maximizes risk dispersion. Diluted unit price = cost/position share.

Position share is the number of user positions announced by the fund company at liquidation.

Dilution cost = ∑ confirmed amount of purchase/transfer-∑ confirmed amount of sale/transfer-∑ cash dividend-∑ confirmed amount of forced redemption;

Diluted unit price = cost/position share;

Cumulative profit and loss = position share * latest net value-diluted cost; Cumulative profit and loss rate = cumulative profit and loss/diluted cost; Daily profit and loss = (today's net value * today's share-today's cost)-(yesterday's net value * yesterday's share-yesterday's cost). Remarks: 1. When the dilution cost is less than or equal to 0, the cumulative profit and loss rate is not calculated; 2. When all product positions are sold, relevant income information will not be retained.
