Step 1: Understanding the Concept:
Minimum subscription is a statutory requirement designed to prevent companies from starting business with inadequate capital. The directors must estimate the minimum funds required to cover startup and initial operational costs.
Step 2: Detailed Explanation:
The funds raised through a public issue of shares must be enough to satisfy several fundamental business needs:
1. Asset Acquisition (A): Buying land, buildings, or machinery needed for production.
2. Issue Costs (B): Covering formation costs like preliminary expenses, underwriting commissions, and brokerage fees.
3. Working Capital (C): Providing liquidity for day-to-day operations like raw material purchase and wages.
4. General Expenditures (D): Any other costs necessary for the usual conduct of business operations.
Since all these points represent basic financial requirements to start a viable business, the minimum subscription must cover all of them collectively.
Step 3: Final Answer:
All the items listed (A, B, C, and D) are valid components that the directors consider when determining the minimum subscription amount.
Therefore, the correct option is (a).
