What Is a Sinking Fund?

Let me explain what a sinking fund is directly to you. It's a fund where money is set aside or saved specifically to pay off a debt or bond. If a company issues debt, they know they'll have to pay it back eventually, and a sinking fund makes that easier by softening the impact of a big revenue outlay. You establish this fund so the company can add to it over the years before the bond matures.

Understanding a Sinking Fund

You should know that a sinking fund helps companies that have issued bonds as debt to save money gradually and avoid a massive payment when the bond matures. Some bonds come with a sinking fund attached, and the prospectus will list the dates when the issuer can redeem the bond early using this fund. While it's mainly for paying off debt, companies sometimes use it to buy back preferred shares or outstanding bonds.

Benefits of a Sinking Fund

One key benefit is lower default risk. A sinking fund adds safety to corporate bond issues for investors because funds are set aside for maturity, reducing the chance of default. This means the amount owed at maturity is much smaller, protecting investors if the company goes bankrupt or defaults. It also eases investor concerns about default, attracting more people to the bond issuance.

Another advantage is improved creditworthiness. With added security and lower default risk, bond interest rates are usually lower, making the company appear more creditworthy and leading to better credit ratings. This increases demand for the bonds, which helps if the company needs to issue more debt later.

It also boosts cash flow and profitability. Lower interest rates cut debt-servicing costs, improving cash flow and profits over time. If the company is doing well, investors are more likely to buy in, raising demand and allowing easier capital raises when needed.

Callable Bonds

If the bonds are callable, the company can pay off part of them early using the sinking fund when it makes sense financially. These bonds have a call option, giving the issuer the right to buy them back. The prospectus details when they can be called, the price levels, and how many, with callable bonds often selected randomly by serial numbers.

Callable bonds are typically redeemed slightly above par value, with higher values for earlier calls. For instance, a bond called at 102 means $1,020 per $1,000 face value, dropping to 101 after a year. If interest rates fall after issuance, the company can issue new debt at lower rates and use proceeds to call the old bonds, refinancing effectively.

If rates drop and bond prices rise, the company might call them at face value, which is below market, meaning investors lose future interest but the company saves money.

Other Types of Sinking Funds

Sinking funds aren't just for bonds; they can buy back preferred stock, which often pays better dividends than common shares. A company might set aside cash in a sinking fund to retire preferred stock, sometimes with a call option allowing repurchase at a set price.

Business Accounting of Sinking Funds

In accounting, you list a sinking fund as a noncurrent or long-term asset on the balance sheet, often under long-term investments. Capital-intensive companies, like those in oil and gas, issue long-term bonds for new equipment and use sinking funds to manage that debt, as they need lots of capital for operations like rigs and drilling.

Example of a Sinking Fund

Take ExxonMobil as an example: suppose they issued $20 billion in long-term bonds with semiannual interest. They set up a sinking fund requiring $4 billion annual payments to pay down debt. By year three, they've cleared $12 billion of the $20 billion.

Without the fund, they'd pay the full $20 billion in year five from profits or cash, plus five years of interest. If oil prices dropped or the economy worsened, they might face cash shortages and struggle with payments. Using the sinking fund saves on interest and avoids long-term financial trouble, plus it lets them borrow more if needed, as only $8 billion remains by year three, showing a strong repayment history.

Is a Sinking Fund a Current Asset?

No, a sinking fund isn't a current asset. It's on the balance sheet as an asset, but not for working capital, so it doesn't count as current—those are assets convertible to cash within a year.

What Is the Difference Between a Sinking Fund and an Emergency Fund?

A sinking fund is for one purpose: paying down debt or bonds. An emergency fund is a general reserve for any unexpected issues. Though both have specific uses, their functions differ—the emergency one covers broader emergencies.

What Are the Disadvantages of a Sinking Fund?

The main downside is it ties up cash, limiting what's available for investments and potential returns. Some argue this isn't a true disadvantage since the fund pays off debt raised for business needs, making it a smart way to manage finances prudently.

The Bottom Line

In summary, sinking funds are how corporations pay off debt methodically. By setting aside money, companies manage obligations wisely when debt matures. Those that don't might scramble for capital to cover debts, leading to struggles.
