Inventory reporting utilizes several key performance indicators to measure efficiency and financial impact. Inventory turnover measures how often inventory is sold and replaced. Weeks of supply (or days of supply) indicates the duration the current inventory can sustain sales. Average aggregate inventory provides the total value of inventory held. All three are standard, fundamental metrics used in financial statements and operational reports to evaluate inventory management performance. Therefore, they are all typical formats for reporting.

A: This is incomplete. Inventory turnover and average aggregate inventory are also standard and essential reporting measures used alongside weeks of supply.

B: This is incomplete. Weeks of supply and inventory turnover are critical performance metrics that provide context beyond just the total inventory value.

C: This is incomplete. Weeks of supply and the average aggregate inventory value are also fundamental reporting formats for a comprehensive view.
