What Does It Mean When a Bond Has a Sinking Fund?
A sinking fund is a means of repaying funds borrowed through a bond issue through periodic payments to a trustee who retires part of the issue by purchasing the bonds in the open market. The sinking fund provision is really just a pool of money set aside by a corporation to help repay previous issues and keep it more financially stable as it sells bonds to investors.
- A sinking fund is maintained by companies for bond issues, and is money set aside or saved to pay off a debt or bond.
- Bonds issued with sinking funds are lower risk since they are backed by the collateral in the fund, and therefore carry lower yields.
- Paying debt off early through a sinking fund saves a company interest expense and puts the company on firmer financial footing.
- Sinking funds can also be used to finance the redemption of callable bonds.
How Bond Repayment Works
Typically, corporate bond agreements (also called indentures) require a company to make periodic interest payments to bondholders throughout the life of the bond, and then repay the principal amount of the bond at the end of the bond’s lifespan.
For example, let’s say Cory’s Tequila Company (CTC) sells a bond issue with a $1,000 face value and a ten-year life span. The bonds would likely pay interest payments (called coupon payments) to their owners each year. In the bond issue’s final year, CTC would need to pay the final round of coupon payments and also repay the entire $1,000 principal amount of each bond outstanding.
This could pose a problem because while it may be very easy for CTC to afford relatively small $50 coupon payments each year, repaying the $1,000 might cause some cash flow problems, especially if CTC is in poor financial condition when the bonds come due. After all, the company may be in good shape today, but it is difficult to predict how much spare cash a company will have in ten years’ time.
Why Create a Sinking Fund?
To lessen its risk of being short on cash ten years from now, the company may create a sinking fund, which is a pool of money set aside for repurchasing a portion of the existing bonds every year. By paying off a portion of its debt each year with the sinking fund, the company will face a much smaller final bill at the end of the 10-year period.
As an investor, you need to understand the implications a sinking fund can have on your bond returns. Sinking fund provisions usually allow the company to repurchase its bonds periodically and at a specified sinking fund price (usually the bonds’ par value) or the prevailing current market price. Because of this, companies generally spend the dollars in their sinking funds to repurchase bonds when interest rates have fallen (which means the market prices of their existing bonds have risen), as they can repurchase the bonds at the specified sinking fund price, which is lower than the market price.
Callable Bonds vs. Sinking Funds
This mechanism may sound very similar to a callable bond, but there are a few important differences investors should be aware of. First, there is a limit to how much of the bond issue the company may repurchase at the sinking fund price (whereas call provisions generally allow the company to repurchase the entire issue at its discretion).
However, sinking fund prices established in bond indentures are usually lower than call prices, so even though an investor’s bond may be less likely to be repurchased through a sinking fund provision than a call provision, the holder of the bond with the sinking fund stands to lose more money should the sinking fund repurchase actually occur.
Where Does a Sinking Fund Arrangement Show Up on a Company’s Balance Sheet?
If a company utilizes a sinking fund in relation to a bond issue, the sinking fund is listed as a long-term (noncurrent) asset on the balance sheet. Since the money in the sinking fund is reserved strictly for the repayment of bonds, it cannot be used to pay for short-term liabilities.
When Did Sinking Funds Originate?
Sinking funds have appeared throughout history, mainly as ways for sovereign governments to help repay war bonds and reduce national debts. Some of the earliest mentions date back to middle-ages Italian city-states, but the sinking fund concept is often attributed to efforts by the English crown during the 17th and 18th centuries.
What Is a Sinking Fund for Personal Budgeting?
Similar in concept to a sinking fund for a corporation that issues and repays bonds, a sinking fund for household finances involves setting aside a certain amount of money each month to help pay off debts or to finance large purchases in the future. The idea is that by consistently saving relatively small amounts of money, there will eventually be enough stored up to spend toward something more significant.
The Bottom Line
A sinking fund provision makes a bond issue simultaneously more attractive to an investor (through the decreased risk of default at maturity) and less attractive (through the repurchase risk associated with the sinking fund price). Investors should review the details of a sinking fund provision in a bond’s indenture and determine their own preferences before investing their money into any corporate bond.
