This excerpt taken from the MRO 10-K filed Mar 1, 2007.
If the transfer of ownership of various assets and operations by Marathon's former parent entity to Marathon was held to be a fraudulent conveyance or transfer, United States Steel's creditors may be able to obtain recovery from us or other relief detrimental to the holders of our common stock.
In July 2001, USX Corporation ("Old USX") effected a reorganization of the ownership of its businesses in which it created Marathon as its publicly owned parent holding company and transferred ownership of various assets and operations to Marathon, and it merged into a newly formed subsidiary which survived as United States Steel.
If a court in a bankruptcy case regarding United States Steel or a lawsuit brought by its creditors or their representative were to find that, under the applicable fraudulent conveyance or transfer law:
then that court could determine those transactions entitled one or more classes of creditors of United States Steel to equitable relief from us. Such a determination could permit the unpaid creditors to obtain recovery from us or could result in other actions detrimental to the holders of our common stock. The measure of insolvency for purposes of these considerations would vary depending on the law of the jurisdiction being applied.
