What it means
The structure exists mainly because of tax. In several markets, bonds issued by or through a public body pay interest that is exempt from income tax, which lets investors accept a lower yield for the same risk.
A hospital, university, airport or affordable housing developer can therefore borrow more cheaply by routing an issue through a conduit issuer such as a state development authority. The conduit issues the bonds, passes the cash to the borrower, and the borrower's loan payments flow back out to bondholders through a trustee.
The critical point for investors is that the conduit issuer is not on the hook. If the underlying borrower fails to pay, bondholders take the loss, and the authority whose name sits on the bond has no obligation to step in.
Credit analysis therefore has to focus entirely on the private borrower rather than the public-sounding issuer. Conduit deals carry costs a straight bank loan does not: an issuer application fee, an annual administration fee, bond counsel, a trustee and often a rating or a credit enhancement.
Those fixed costs mean the structure only pays for itself when the borrowing is large, long-dated and the interest saving is genuinely material. You will also see the phrase used more loosely in corporate finance for any pass-through borrowing vehicle, including special purpose entities that issue commercial paper backed by receivables.
The common thread is that the named issuer is a legal channel rather than the real credit risk.
In practice
Real-world examples.
Example
A private university raises $75,000,000 through a state education facilities authority to build student accommodation. The authority's name appears on the bonds, but the offering document states in bold that repayment depends solely on the university's revenues.
Example
A manufacturer expands a plant using $12,000,000 of industrial development bonds issued by a county development agency. The agency collects a modest annual fee, the manufacturer pays a below-market interest rate, and the county gets the jobs it wanted without lending a cent of its own money.
Example
An investment manager reviewing a municipal bond portfolio spots that a third of its holdings are conduit issues for single hospitals and nursing homes. She reclassifies them as corporate-style credit exposure rather than government exposure, and reduces the position.
Formula
Calculation
Annual interest saving = Principal x (Taxable rate - Conduit rate), less the issuer's ongoing fees.
A regional care provider needs $20,000,000 for a new facility. A commercial bank offers a taxable loan at 6.0%, while a tax-exempt conduit issue arranged through a state development authority prices at 4.0%.
Gross annual interest saving = $20,000,000 x (6.0% - 4.0%) = $20,000,000 x 2.0% = $400,000.
The authority charges an annual administration fee of 0.10% of principal: $20,000,000 x 0.10% = $20,000.
Net annual saving = $400,000 - $20,000 = $380,000.
Upfront issuance costs, covering bond counsel, the trustee, the rating and the issuer's application fee, come to $600,000. Payback = $600,000 / $380,000 = about 1.6 years on a twenty year borrowing, so the structure is clearly worth the extra complexity.Case study
Seen in the real world.
This illustrative example uses a fictional organisation. Fenwick Valley Hospice, a charity running three residential care sites, needed $20,000,000 to replace an ageing building. Its bank quoted 6.0% on a fifteen year term loan with a full package of covenants.
Its advisers instead arranged a conduit issue through a fictional state health facilities authority, which priced at 4.0%. After the authority's 0.10% annual fee, Fenwick saved $380,000 a year, which was roughly the running cost of one additional ward.
The trade-off was disclosure and time. The deal took seven months rather than six weeks, required audited figures for three years, and left the hospice with continuing reporting duties to bondholders. Fenwick's trustees concluded the saving justified it, but noted that a $3,000,000 borrowing would never have cleared the fixed costs.
Watch out
Common mistakes.
- Believing the government body behind the bond guarantees repayment. In a conduit deal the issuer is a pass-through and bondholders rely entirely on the private borrower.
- Comparing only the headline interest rates. Issuer fees, trustee costs and continuing disclosure obligations have to be netted off before the saving is real.
- Assuming any borrower can use a conduit. Eligibility is restricted by statute to defined purposes such as healthcare, education, housing and certain industrial projects.
Questions
People also ask.
Why would a public authority lend its name to a private borrower?
Because it wants the project built in its area, and acting as a conduit costs it nothing beyond administration, for which it charges a fee.
Does conduit financing appear on the issuer's balance sheet?
No, the debt sits with the underlying borrower, and the conduit issuer records neither the asset nor the liability.
Is there a minimum practical size?
In practice yes, because the fixed issuance costs mean most conduit deals need to be in the tens of millions before the interest saving outweighs them.
