What it means
Public projects rarely line up neatly with bond markets. A city may need to start paying contractors in March, while the permanent bond issue that funds the project cannot be brought to market until October because of approvals, valuations or simply better pricing conditions.
The bond anticipation note fills that gap, typically running from a few months up to three years. The distinguishing feature is the repayment source.
Ordinary short-term borrowing is repaid from operating revenue, whereas a BAN is designed to be repaid from the proceeds of a specific future bond sale that has already been authorised. That gives lenders comfort, because they are lending against a planned capital markets transaction rather than against next year's tax collections alone.
The main risk is called rollover or takeout risk. If the permanent bond issue is delayed, repriced badly or blocked, the issuer must either refinance the note with another note or find the cash elsewhere, and both options can be expensive if interest rates have moved against it.
This is why credit analysts look closely at how many times an issuer has already rolled the same note. Pricing usually sits below long-term bond yields when the yield curve slopes upwards, which is one reason issuers like them.
Interest is often paid at maturity along with the principal rather than in periodic coupons, and the notes are commonly sold to money market funds and banks that want short-dated exposure. Many are tax-exempt in their home jurisdiction, which lowers the coupon further.
Businesses encounter BANs from two directions. Contractors and suppliers to public bodies benefit because the note is what allows the project to start paying, and corporate treasurers sometimes hold them as short-dated investments.
In both cases the practical question is the same: how firm is the planned bond issue that will eventually repay the note.
In practice
Real-world examples.
Example
A school district needs to begin a $12 million rebuild before the summer holidays but cannot complete its bond authorisation until the autumn. It issues a bond anticipation note to fund the first phase and repays it from the bond proceeds four months later.
Example
A city transport agency issues a two year BAN to buy land for a depot while it finalises the environmental approvals required for the permanent bond issue. Its credit rating is affirmed only after the rating agency confirms the bond authorisation is already in place.
Example
A corporate treasurer with $3 million of surplus cash buys short-dated bond anticipation notes from a well rated municipal issuer, preferring the yield to a bank deposit while keeping the maturity under twelve months.
Formula
Calculation
Interest on a bond anticipation note = Principal x Annual interest rate x (Months outstanding / 12). Total repayment at maturity = Principal + Interest.
A county authority approves an $8,000,000 water treatment upgrade and expects to issue 20 year bonds in nine months, once the engineering design is signed off. To start construction immediately it issues a bond anticipation note of $8,000,000 at an annual rate of 3.5% for nine months, with interest payable at maturity.
Interest = $8,000,000 x 3.5% x (9 / 12)
Interest = $8,000,000 x 0.035 x 0.75 = $210,000
Total repayment = $8,000,000 + $210,000 = $8,210,000
Nine months later the authority sells its long-term bonds and uses $8,210,000 of the proceeds to retire the note. The $210,000 of short-term interest is the cost of starting nine months earlier, and it is normally capitalised into the total project cost rather than charged to the operating budget.Case study
Seen in the real world.
Fairmont Valley Water Authority is an invented public body used here as an illustrative example. It needed to replace an ageing pumping station before the winter and issued a $6,000,000 bond anticipation note at 3% for twelve months, expecting to complete a permanent bond issue the following autumn. The interest cost of $180,000 was built into the project budget without difficulty.
The permanent issue was then delayed by a dispute over the valuation of the site, and the authority had to roll the note for a further year. By then short-term rates had risen, and the replacement note priced at 4.75%, lifting the second year interest cost to $285,000 on the same $6,000,000 principal. The extra $105,000 came straight out of the operating budget, because the project contingency had already been spent.
This illustrative example shows why analysts treat repeated rollovers as a warning sign rather than routine administration. Fairmont Valley responded by requiring that no future note be issued unless the permanent bond authorisation is complete and the underwriting syndicate is appointed, which removed most of the timing risk from later projects.
Watch out
Common mistakes.
- Treating a BAN as permanent funding. It is bridging finance with a fixed maturity, and the issuer still has to complete the long-term bond issue that repays it.
- Ignoring the short-term interest cost when budgeting a project. That interest is a genuine project cost and should be included in the capital budget from the start.
- Assuming a rollover is always available on similar terms. Rates and appetite can change quickly, and an issuer forced to refinance in a worse market pays materially more.
Questions
People also ask.
What repays a bond anticipation note?
The proceeds of the long-term bond issue it anticipates, which is what separates it from short-term borrowing repaid out of tax or operating revenue.
Are these notes risky for an investor?
They are generally low risk when the issuer is well rated and the permanent bond issue is authorised, but the key question is takeout risk, meaning whether that bond issue will actually complete.
Why not just wait and issue the bonds?
Waiting delays the project, and construction inflation or a missed seasonal window often costs more than the few months of short-term interest.
