Answer: When inventory increases over the period, variable net income will exceed absorption net income.
Step-by-step explanation:
In comparing the absorption and variable cost methods, the statements that are true are:
• SG&A fixed expenses are not included in inventory in either method.
• Only the absorption method may be used for external financial reporting.
• Variable costing charges fixed overhead costs to the period they are incurred.
Therefore, option D is wrong which states that "when inventory increases over the period, variable net income will exceed absorption net income".
