Discount is to protect the principal and income of a certain share (low risk) in the graded fund.

After the discount, A share, B share and the net value of the parent fund are reclassified as 1, and the leverage ratio is reclassified as the contract design leverage ratio.

So, when the discount occurs, your market value is 450, so your share is 450. This operation does not affect the change of the overall net value.
