Q.Explain the classification of sources of business finance on the basis of

This question calls for a structured, multi-part explanation covering all three classification bases together.

Sources of business finance are classified on three different bases, each highlighting a different aspect of the source concerned.

1. Classification by period: Long-term sources are needed for more than five years and typically finance fixed assets or permanent working capital, for example equity shares, preference shares, debentures and long-term institutional loans. Medium-term sources are needed for one to five years, for example medium-term bank loans and public deposits accepted for a few years. Short-term sources are needed for less than a year, mainly to finance day-to-day working-capital needs, for example trade credit, bank overdraft and commercial paper.
2. Classification by ownership: Owned funds are contributed by the owners of the business and involve no fixed, compulsory payment — examples are equity shares, preference shares and retained earnings. Borrowed funds are raised from outside lenders who must be repaid with a fixed rate of interest regardless of the firm's profit, for example debentures, institutional loans, public deposits and trade credit.
3. Classification by source of generation: Internal sources are generated from within the business's own operations, chiefly through retained earnings (ploughing back of profits) and sale of surplus assets, and involve no cost of raising and no dilution of control. External sources are raised from outside the business, such as through a fresh issue of shares or debentures, borrowing from a bank or financial institution, or accepting public deposits; these can supply much larger amounts but usually involve some cost and procedural formality. The table below summarises how a few common sources fall under all three classifications simultaneously:

As the table shows, the same source can be classified simultaneously under all three bases — for instance, equity shares are long-term, owned and external all at once — which is why understanding all three classifications together, rather than any one in isolation, gives the fullest picture of a source's true nature.

A common mistake is treating the three classifications as mutually exclusive alternatives, describing a source under only ONE basis — in fact every source should be placed simultaneously under all three headings (period, ownership, and generation), as the comparison table illustrates.
