An undervalue transaction is a transaction entered into by a company who subsequently goes into bankruptcy which the court orders be set aside, usually upon the application of a liquidator for the benefit of the debtor's creditors. Under Australian insolvency law they are referred to as uncommercial transactions.
Under ordinary principles of contract law, the courts will not generally look into the adequacy of the consideration provided by either side. However, if a company is in real peril of going into bankruptcy, many legal systems provide a mechanism that transactions which are seriously commercially disadvantageous to the company can be unwound, so as to prevent prejudice to the creditors of the company.
Normally, for a transaction to be set aside as an undervalue transaction, the liquidator or equivalent must demonstrate that:
The vulnerability period is the period of time immediately prior to the company going into bankruptcy. The length of the vulnerability period varies between countries, and some countries apply different vulnerability periods in different circumstances. For example, in the United Kingdom, the vulnerability period is either:
The period is calculated by reference to the period of time immediately preceding the company going into liquidation or administration.
The effect of a successful application to have a transaction declared as an undervalue transaction varies. Inevitably the other party to the transaction who received the benefit has to return the benefit (or account for it) it to the liquidator. In some countries the assets are treated in the normal way, and may be taken by any secured creditors who have a security interest which catches the assets (characteristically, a floating charge). However, some countries have "ring-fenced" recoveries of unfair preferences so that they are made available to the pool of assets for unsecured creditors.
Many jurisdictions which have prohibitions on undervalue transactions also provide for an exception in the case of transactions entered into in the ordinary course of business where the directors are of a view that it is for the benefit of the company, and such transactions are usually either validated or presumed to be validated.
