Answer:
A) The GAAP statement is based on cost function rather than cost behavior.
Step-by-step explanation:
Income statements that follow GAAP rules categorizes expenses based on their business function: product, selling or administrative.
While cost behavior categorizes costs based on how they influence a company's activities: variable, fixed and mixed. When a manager wants to measure the impact of any decision he/she makes, they need to use this type of categorization. For example, if fixed costs increase, what is the new break even point? If variable costs decrease, how is the marginal cost affected?
