For each of the following independent cases, state the highest level of deficiency that you believe the circumstances representa control deficiency, a significant deficiency, or a mate- rial weakness. Explain your decision in each case. The company uses a standard sales contract for most transactions, although sales personnel are allowed to modify sales contract terms as necessary to make a profitable sale.

The changes in the standard shipping terms could require a delay in the timing of revenue recognition. Management reviews gross margins on a monthly basis and investigates any significant or unusual relationships. In addition, management reviews the reasonableness of inventory levels at the end of each accounting period. The company has experienced limited situations in which revenue has been inappropriately recorded in advance of shipment, but amounts have not been material.
