Louisiana-Pacific Corp (LP) and Weyerhaeuser Co are among the 947 US companies required to file sworn statements with the US Securities and Exchange Commission affirming the accuracy of their financial reports.

The move is part of new legislation following the collapse of organisations such as Enron and WorldCom whose management were deemed not to be liable for their company accounts.

Now two top executives are required personally to vouch for the accuracy of their company’s financial statements.

Chairman Mark Suwyn and chief financial officer Curtis Stevens filed sworn statements for LP while chairman Steve Rogel and chief financial officer William Stivers did the same for Weyerhaeuser.
