Danshui Plant No. 2 has a one-year contract with Apple to assemble 2.4 million iPhone 4 units but is concerned they will not meet the target as production after 3 months is only 180,000 units. The plant manager Wentao Chen is anxious because operating at this production level results in losses. The document provides production details for 180,000 units in August and calculates variances to determine where costs differ from the standard budget.
