When the mortgage right is infringed, the mortgagee has the right to request to remove the infringement or compensate for the losses, whether it is the infringement of the subject matter of the mortgage right or the direct infringement of the mortgage right.

The value of mortgaged assets after deducting impairment and depreciation is called net worth.

As far as joint-stock companies are concerned, the net asset value is usually calculated according to the book value of assets and liabilities, that is, the net asset value per share = (total assets-total liabilities)/number of common shares. 2. As far as funds are concerned, the net asset value refers to the balance of the total market value of fund assets calculated at fair value after deducting liabilities, which is the rights and interests of fund share holders. The process of calculating the fair value of fund assets is the valuation of the fund, that is, the net asset value of the unit fund = (total assets-total liabilities)/total fund shares.
