Yes, you are right.

Reasons for Long-Term Investments in a Proprietorship Firm:

1. Capital Appreciation: Long-term investments in a proprietorship firm are made with the intention of generating capital appreciation over an extended period. The firm expects the value of these investments to increase over time, thereby providing a substantial return on investment.

2. Diversification: By investing in various long-term assets such as stocks, bonds, real estate, or mutual funds, a proprietorship firm can diversify its portfolio and reduce risk. Diversification helps in ensuring stable returns and minimizing the impact of volatility in any particular investment.

3. Income Generation: Some long-term investments, such as dividend-paying stocks or rental properties, can generate a regular income stream for the firm. This income can be utilized for meeting operational expenses, supporting growth initiatives, or reinvesting in additional assets.

4. Tax Benefits: Certain long-term investments offer tax advantages, such as tax-exempt municipal bonds or tax-deferred retirement accounts. These investments can help reduce the firm's overall tax burden and optimize its financial position.

5. Business Expansion: Long-term investments can also serve as a strategic tool for business expansion. For example, a proprietorship firm may invest in acquiring another business or establishing a subsidiary to diversify its operations and tap into new markets.

Non-Current Investments and their Purpose:

1. Lack of Purpose: Unlike long-term investments, non-current investments do not necessarily have a specific purpose or objective. They are typically made with surplus funds that the firm does not require for immediate operational needs.

2. Liquidity Management: Non-current investments may be used to manage liquidity by parking excess funds in low-risk instruments such as government securities or treasury bills. These investments provide a safe and liquid avenue for temporarily holding funds until they are needed for business operations.

3. Contingency Planning: Non-current investments can also serve as a contingency or emergency fund for a proprietorship firm. These investments act as a financial buffer, providing resources to address unforeseen events or financial difficulties.

4. Strategic Opportunities: Non-current investments may be made to take advantage of strategic opportunities that may arise in the future. For example, if a lucrative investment opportunity is expected to emerge in the market, a firm may invest in non-current assets to be prepared to capitalize on it when the time is right.

5. Mitigating Inflation: By investing in non-current assets like real estate or commodities, a proprietorship firm can hedge against inflation. These investments have the potential to appreciate in value over time, thereby offsetting the impact of inflation on the firm's overall financial position.

In summary, while long-term investments in a proprietorship firm have a clear purpose of capital appreciation, diversification, income generation, tax benefits, and business expansion, non-current investments serve mainly as a means of liquidity management, contingency planning, strategic opportunities, and inflation mitigation.
