An analyst is forecasting operating costs for a company with relatively high fixed costs, sensitivity to economic conditions, and commodity inputs with volatile pricing. The company does not follow a hedging strategy for commodity purchases but tries to buy when prices are low. Which of the following is most appropriate to use in forecasting operating costs? The analyst uses:

选项：

A.

analyst discretion to forecast all operating costs

B.

management guidance to forecast all operating costs

C.

management guidance to forecast fixed operating costs and analyst discretion to forecast variable operating costs

解释：

C is correct. Management has an advantage in forecasting for objects that are subject to its actions (such as capital expenditures and inventories, which affect fixed costs). The analyst is likely to have an informational advantage when it comes to forecasting economic conditions and commodity prices, which affect revenues and variable costs.
