the security "floats", they remain free to deal with the assets and dispose of them in the ordinary course of business, thereby obtaining the maximum credit benefit from the lender, but without the inconvenience of requiring the secured creditor's consent to dispose of stock in trade. However, in many jurisdictions, floating charges are required to be registered in order to perfect them; otherwise they may be unenforceable on the bankruptcy of the debtor. This registration requirement has often led to other property rights (such as rights under a defective retention of title clause), which have been re-characterized as a floating charge being held to be void for non-registration. Remedies Broadly speaking, holding a floating charge gives the secured creditor two key remedies in the event of non-payment of the secured debt by the company. Firstly, the secured creditor can crystallise the charge, and then sell off any assets that the charge then attaches to as if the charge was a fixed charge. Secondly (and more frequently the case, to preserve the company as a going concern), if the floating charge encompasses substantially all of the assets and undertaking of the company, the secured creditor can appoint an administrative receiver to take over the management and control of the business with a view to discharging the debt out of income or selling off the entire business as a going concern. In countries that permit the making of an administration order, the floating charge had another key benefit. The holder of a floating charge could appoint an administrative receiver and block the appointment of a court-appointed administrator, and thus retain control of the distribution of the assets of the company. Practice became such that companies were asked to give "lightweight" floating charges to secured lenders which had no collateral value purely to allow the holders to block administration orders, an approach that was approved by the courts in Re Croftbell Ltd [1990] BCC 781. In the United Kingdom the law has now been changed by statute, but the power to block appointments of administrators has been retained in many other common law jurisdictions. Crystallisation Strictly speaking, it is not possible to enforce a floating charge at all - the charge must first crystallise into a fixed charge. In the absence of any special provisions in the relevant document, a floating charge crystallises either upon the appointment of a receiver or upon the
