A form of security for a debt. Instead of naming a specific property, which can be taken by the creditor if the debtor defaults (as in a fixed charge like a mortgage), a class of goods or assets is named, such as the debtor's stock. This allows the debtor to trade in the assets freely, but if the debtor fails to make repayments then the floating charge becomes a fixed charge (known as crystallisation) over all the stock at that time. The creditor can then take and sell it to recover the debt.
