Addeco SA is the world’s largest temporary employment company. It lost several major accounts because customers felt it was not adequately serving their complex staffing needs. It announced that it was not able to deliver its 2003 financial statements on schedule. Ernst & Young, its auditors, raised questions about accounting and controls as part of an intensive review of internal controls as mandated by the Sarbanes-Oxley Act. It appears that Addeco recorded revenue for temporary services provided during the first several weeks in January 2004 as 2003 revenue.
