During the most recent audit, Rivers concluded that sales totaling $11,000 were recognized as of December 31,2010, that did not meet the criteria for recognition until 20011. When Rivers discussed these sales with turner, the chief financial officer of charger company, Turner asked Rivers about the performance materiality level used in the audit, which was $25,000. Upon learning of this,Turner remarked, Then there's no need to worry, it's not a material amount. Why should we bother with this item?
