Money set aside periodically into a dedicated fund to repay a debt or replace a major asset at a future date, reducing default risk.
A Sinking Fund is a reserve built up by making regular deposits (typically annually or semi-annually) into a segregated account or investment, designed to accumulate enough to meet a specific future obligation. Common uses include: repaying debentures/bonds at maturity, replacing expensive machinery or equipment, and building reserves for infrastructure projects. The deposits earn compound interest, reducing the total amount the company needs to set aside. For bondholders, a sinking fund requirement provides additional security — it ensures the issuer is systematically saving for repayment rather than scrambling at maturity. In accounting, the sinking fund appears as an investment (asset), and the sinking fund reserve appears in equity. Under Ind AS, it's classified based on the nature of the underlying investment.
Company issues ₹1 crore debentures repayable in 5 years. Sets up sinking fund with 10% annual return. Annual deposit: ₹1,00,00,000 ÷ FV factor (6.1051) = ₹16,38,000. Year 1: Deposit ₹16,38,000. Year 2: ₹16,38,000 + Interest ₹1,63,800 + Deposit ₹16,38,000 = ₹34,39,800. By Year 5: ₹1,00,00,000 accumulated.

Not always. It depends on the debt instrument's terms. Debenture trust deeds or bond indentures may require a sinking fund as a covenant. For internal asset replacement, it's voluntary but prudent. Under the Companies Act, certain debenture issues require creation of a Debenture Redemption Reserve (DRR), which serves a similar purpose.
Typically in low-risk, liquid investments: government securities, high-rated bonds, fixed deposits, or mutual fund debt schemes. The goal is capital preservation with reasonable returns — not capital appreciation. The investment must be easily liquidatable when the fund's purpose is due.
