No, the statement is not entirely correct.

Explanation:
Long-term investments:
Long-term investments are assets that a business entity holds for a long period of time, typically exceeding one year. These investments are not intended for immediate resale and are expected to provide future benefits to the business.

Truck and building machinery:
Trucks and building machinery are commonly used in business operations, but they do not necessarily qualify as long-term investments. These assets are typically classified as fixed assets or property, plant, and equipment (PP&E) on a company's balance sheet.

Fixed assets:
Fixed assets are tangible assets that are used in the production or supply of goods and services, for rental purposes, or for administrative purposes. They are expected to provide economic benefits to the business entity for more than one year.

Key differences:
While both long-term investments and fixed assets are held for an extended period, there are key differences between the two:

1. Purpose: Long-term investments are held primarily for earning returns on investment, such as stocks, bonds, or real estate properties. In contrast, fixed assets are used directly in the business operations to generate revenue.

2. Nature of benefits: Long-term investments generate returns in the form of dividends, interest, or capital gains. On the other hand, fixed assets provide operational benefits by enhancing production capacity, improving efficiency, or supporting business activities.

3. Accounting treatment: Long-term investments are reported at fair value on the balance sheet, with changes in value recognized in the income statement. Fixed assets, including trucks and building machinery, are initially recorded at cost and subsequently depreciated over their useful lives.

Conclusion:
Therefore, while trucks and building machinery are important assets used in business operations, they are typically classified as fixed assets rather than long-term investments. Long-term investments generally refer to financial instruments held for the purpose of earning returns, while fixed assets are tangible assets used in the production or supply of goods and services.
