Fixed capital components: Which of the following is not part of the fixed capital investment for a chemical plant facility?

Introduction / Context:
Accurate classification of fixed versus working capital is essential for estimating total capital investment and for cash-flow modeling. Fixed capital relates to long-lived assets installed to make the plant operational, whereas working capital covers current assets used in day-to-day operations.

Given Data / Assumptions:

• Fixed capital includes process equipment, installation, buildings, site development, utilities plants, and safety/emergency facilities.
• Working capital includes inventories (raw materials, intermediates, products), cash, and receivables.

Concept / Approach:
Raw materials inventory is a current asset that turns over with production and sales; hence it is working capital, not fixed capital. In contrast, utilities plants, process equipment, buildings, and emergency facilities are fixed assets that remain in service for many years.

Step-by-Step Solution:
List fixed asset examples: process equipment, utilities, buildings, emergency systems.Identify current assets: raw materials inventory.Choose the item that is not fixed capital: raw materials inventory.

Verification / Alternative check:
Review standard project cost summaries: inventories are accounted for in working capital estimates, often as a multiple of monthly operating costs.

Why Other Options Are Wrong:
Utilities plants / process equipment / emergency facilities / buildings: These are core parts of fixed capital.

Common Pitfalls:
Placing inventories under fixed capital because they are purchased at start-up. Despite initial purchase, they remain circulating current assets and should be budgeted as working capital.

Final Answer:
Raw materials inventory
