Conduit Bond Obligor: Covenants, Tax-Exempt Rules, and Disclosure

A conduit bond obligor is the private company or nonprofit that actually borrows and repays tax-exempt bonds issued in a state or local government’s name. The government lends its borrowing authority so the obligor can access lower municipal-market interest rates, but the obligor carries the repayment, tax compliance, disclosure, and recordkeeping duties. The government is not on the hook. If the obligor stumbles on any of those duties, the bonds can lose their tax-exempt status and the penalties can wipe out the interest savings that motivated the deal in the first place.

Who Qualifies as an Obligor

The obligor is the entity that receives the borrowed money, uses it for a capital project, and repays it over time. Governmental accounting standards state plainly that a conduit debt obligation is not a liability of the issuing government; the third-party obligor holds the primary repayment duty.¹

Two categories of obligors dominate. Nonprofit hospitals, universities, and similar organizations borrow through qualified 501(c)(3) bonds. To qualify, substantially all of the financed property must be owned by a 501(c)(3) organization or a governmental unit, and additional requirements apply, including a $150 million cap on outstanding nonhospital bonds per borrower.²

For-profit entities can also serve as obligors, but only through exempt facility bonds, which cover a defined list of project types: airports, docks, mass transit, water and sewage facilities, solid waste disposal, qualified residential rental projects, broadband infrastructure, and carbon dioxide capture facilities, among others.³ The common thread is public benefit. Because the government has no repayment obligation, credit ratings and investor pricing reflect the obligor’s own financial strength, not the issuing government’s taxing power.

Repayment and Financial Covenants

The core duty is straightforward: pay principal and interest on schedule. Payments run through a bond trustee, typically a bank or trust company, which manages accounts and distributes debt service to bondholders. The obligor pays the trustee’s annual administration fee and every other cost tied to the bond lifecycle, including legal fees, issuance expenses, and ongoing compliance work. The conduit government is designed to walk away with no out-of-pocket cost.

Loan agreements almost always require the obligor to maintain a debt service coverage ratio, meaning net revenue must exceed annual bond payments by a specified margin. Falling below that ratio is a technical default even if every payment has cleared, and it can activate remedies under the bond documents. A bad fiscal year is therefore not just a financial problem. It can trigger bondholder protections.

Obligors with weaker credit sometimes arrange third-party backing: bond insurance, letters of credit, surety bonds, or guarantees. A bond insurer promises to cover principal and interest if the obligor cannot, effectively substituting its rating for the obligor’s. These arrangements lower the interest rate but add fees and covenants, and they create a dependency. If the enhancement provider is later downgraded, the bonds themselves get downgraded.

Keeping the Bonds Tax-Exempt

Interest savings on conduit bonds exist only because the IRS treats bondholder interest as exempt from federal income tax. Protecting that status is arguably the obligor’s most consequential ongoing duty, and the rules are stricter than many borrowers expect.

Arbitrage Rebate

When bond proceeds sit invested before being spent on the project, they can earn more than the bond’s own yield. The obligor must rebate those excess earnings to the U.S. Treasury. The calculation runs on five-year intervals from the issue date, and each installment is due within 60 days of the computation date. Every installment must cover at least 90 percent of the rebate amount calculated as of that date, and the final payment is due within 60 days after the last bond is redeemed.⁴

Missing a rebate payment is expensive. For governmental and 501(c)(3) bonds, the penalty is 50 percent of the unpaid amount plus interest. For other private activity bonds, the penalty is 100 percent plus interest. An automatic waiver applies if you pay the full amount within 180 days of discovering the error, provided the issue is not already under IRS examination and the failure was not willful.⁴

Private Business Use

For governmental bonds, no more than 10 percent of bond proceeds may benefit a private business. This looks like a rule for other borrowers, but it reaches conduit deals when a 501(c)(3) obligor leases space, signs management contracts, or enters research agreements with for-profit entities inside a bond-financed facility. If private use creeps above 10 percent, the bonds can be reclassified and lose their tax exemption.⁵ Violations often surface years later, triggered by a lease renewal or a new vendor contract that nobody flagged.

Issuance Costs and Maturity

Federal law caps issuance costs on a private activity bond issue at 2 percent of the proceeds. Exceeding that threshold disqualifies the bonds. Separately, the weighted average maturity of the bonds cannot exceed 120 percent of the average expected useful life of the financed facilities. A hospital borrowing for a building expected to last 30 years cannot structure bonds maturing over more than 36 years.⁶

One pre-issuance point belongs here as boundary: private activity bonds require public approval under TEFRA before they can be sold. An elected representative must approve the bonds after a public hearing with at least seven days’ advance notice identifying the project, location, borrower, and maximum bond amount, and approval must occur within one year before issuance.⁶ The obligor typically drives the paperwork even though the issuer runs the hearing.

SEC Continuing Disclosure

Securities law adds a parallel track through SEC Rule 15c2-12. Under the rule, the obligor (called the “obligated person”) enters a written continuing disclosure agreement that specifies the accounting principles for its financial statements and the date by which annual financial information will be provided. There is no single federal deadline. Each agreement sets its own, typically 120 to 270 days after fiscal year-end.⁷

A common misunderstanding: the rule does not universally require audited financial statements. It requires the agreement to specify whether statements will be audited, and it requires audited statements to be filed “when and if available.” Most agreements do call for audited financials, which makes the audit a contractual obligation rather than a direct SEC mandate.⁷ Filings go to the MSRB’s EMMA system, where investors read them for free.

Material Event Notices

Beyond annual reports, obligors must file notice of specified material events within ten business days of occurrence.⁷ Reportable events include:

Principal or interest delinquencies and non-payment defaults
Rating changes, credit-enhancement substitutions or failures, and unscheduled draws on reserves or credit enhancements reflecting financial difficulty
Bond calls, defeasances, release or substitution of collateral, and modifications to bondholder rights
Bankruptcy, receivership, mergers, or sale of substantially all assets
Adverse tax opinions or events affecting the bonds’ tax-exempt status
Incurrence of additional debt or defaults on other financial obligations reflecting financial difficulties

The SEC has brought enforcement actions against issuers and obligated persons for inaccurate statements about prior disclosure compliance and can seek financial sanctions.⁸ A spotty filing history also makes future bond deals harder to market, because underwriters must assess disclosure compliance before signing on.

Records and Written Compliance Procedures

The IRS recommends, and the bond market increasingly expects, that obligors maintain a written post-issuance compliance policy. The IRS guidance suggests these policies identify the person responsible for monitoring, set regular review intervals, describe how violations get caught and corrected, and require recordkeeping sufficient to substantiate compliance. Form 8038 itself asks whether the issuer has established such written procedures for arbitrage and rebate compliance.⁹

Record retention runs longer than most organizations expect. Material records tied to the bond issue, including expenditure documentation, investment records, private-use tracking, and arbitrage calculations, must be kept as long as the bonds remain outstanding plus three years after the final redemption date. For refunded bonds, records for both the original and refunding issues must be maintained until three years after the later maturity.¹⁰ On a 30-year bond, that can mean holding documents for over three decades. Organizations that lose these records are poorly positioned to survive an IRS examination.

When Something Goes Wrong

IRS Examinations and Voluntary Correction

The IRS examines tax-exempt bond issues and can revoke tax-exempt status outright. If that happens, every bondholder owes federal income tax on the interest they have received, which would gut the bond’s market value and likely trigger litigation against the obligor. In practice, the IRS usually offers a closing agreement instead: correct the violation, pay a resolution amount to the Treasury, and the bonds keep their exemption.¹¹

Obligors who find a problem before the IRS does have a better option. The Tax Exempt Bonds Voluntary Closing Agreement Program lets issuers and other parties self-report violations and negotiate resolution terms that are generally more favorable than what the IRS imposes during an examination.¹² Finding your own problem costs less than having the IRS find it for you, which is the strongest practical case for real post-issuance monitoring.

Default, Cure, and Forbearance

When an obligor breaches the bond agreement, the trustee steps in for investors. The most powerful tool is acceleration: declaring the full outstanding principal and accrued interest immediately due. Availability is limited to specified events of default, and the trust indenture controls which defaults trigger it. If the bonds are secured by physical property, the trustee can pursue foreclosure. Enforcement legal fees typically come out of recovered assets before bondholders get anything.

Default does not always lead straight to acceleration. Most indentures provide a cure period, often 30 to 60 days, for the obligor to fix the problem. Even after cure expires, the trustee and bondholders sometimes agree to forbearance, temporarily refraining from exercising remedies while the obligor pursues restructuring or a capital raise. The obligor must keep meeting other covenants and cooperating during that window.¹³

Forbearance is not forgiveness. The underlying default stays on the books, and the lender preserves every right to accelerate or foreclose if the obligor fails to meet the forbearance terms, misrepresents its financial condition, or stops negotiating in good faith. If the forbearance period ends without resolution, enforcement remedies snap back, often without additional notice.¹³ Read the indenture’s default sequence before issuance, not after a payment is missed.
