Definition of Bond Sinking Fund

A bond sinking fund is a restricted reserve account where a company sets aside money over time to repay or retire its bonds at maturity or periodically before maturity. In Canadian accounting, this fund appears as a non-current asset on the balance sheet and demonstrates the issuer's commitment to meeting future debt obligations.

For example, a manufacturing company in Ontario that issues $5 million in 10-year bonds may create a bond sinking fund by contributing $500,000 annually to ensure it can repay the full amount at maturity.
