Refunding an Outstanding Issue

A refunding replaces outstanding obligations with new ones. Issuers do it to reduce debt service, to remove covenants that have become inconvenient, to restructure a maturity schedule, or to consolidate several issues into one. The legal work divides cleanly. One half asks when the old obligations stop being outstanding under their own documents. The other asks whether the new obligations qualify for excluded interest, and that answer depends on how far in advance the refunding occurs.

The ninety day line

Federal law draws the boundary by timing rather than by structure. A bond is treated as issued to advance refund another bond if it is issued more than ninety days before the redemption of the refunded bond. Inside that window the transaction is a current refunding. Outside it, the transaction is an advance refunding, and the statute provides that nothing in the exclusion provision or in any other law shall be construed to provide an exemption from federal income tax for interest on a bond issued to advance refund another.

The consequence is structural rather than punitive. Issuers that want to capture a rate before a call date now reach it through instruments that are not tax-exempt advance refundings, through forward delivery arrangements, or through tender offers that retire the old obligations sooner. Each carries its own documentation and its own risks, and each has to be tested against the same ninety day definition, which is measured from the issue date of the new bond to the redemption of the old.

Building the escrow

Where the refunded obligations are not retired immediately, proceeds are deposited with an escrow agent under a separate agreement and invested in securities whose scheduled receipts will pay the principal, interest and any redemption premium on their appointed dates. The escrow is a closed system: it is designed to produce cash on exactly the days the escrow agreement calls for it, and it is not managed thereafter. Substitution of securities, where permitted at all, is tightly conditioned.

Two computations are performed before closing and both are verified by an independent accountant. Sufficiency asks whether the escrow will in fact meet every payment when due, tested with no assumption of reinvestment beyond what the agreement provides. Yield asks whether the escrow satisfies the arbitrage restrictions, because the deposit consists of proceeds and the escrow is an investment of them. The verification report is delivered at closing and becomes part of the transcript for both issues.

Defeasance under the indenture

Discharge is governed by the document that created the obligations, not by the tax rules. The discharge article typically requires deposit of cash or specified government obligations sufficient to pay the debt service, an irrevocable notice of redemption where the obligations are to be called, an opinion that the conditions have been satisfied, and sometimes a verification report. Where those conditions are met, the lien of the indenture is released and holders look only to the escrow.

The permitted escrow investments are usually narrow: direct obligations of the federal government, or obligations whose payment is unconditionally guaranteed by it, sometimes with a short list of alternatives. That narrowness is deliberate, because the sufficiency computation assumes the securities will pay exactly as scheduled and no credit judgment is being made afterward. Where the escrow is funded with cash alone, the computation is simpler but the deposit is larger, and issuers weigh that difference at structuring rather than at closing.

Where they are not met, the deposit accomplishes an economic result without a legal one. The obligations remain outstanding, the covenants continue, and any additional bonds test still counts them. That distinction is the reason counsel is asked for a defeasance opinion at all: it is a conclusion that a specific set of conditions in a specific document has been satisfied, and it is delivered only after the escrow has been examined against them.

Proceeds that move between issues

A refunding rearranges the tax accounting of two issues at once. Unspent proceeds of the prior issue become transferred proceeds of the refunding issue as principal of the prior issue is discharged, in a proportion the regulations prescribe. Yield restriction and rebate obligations follow them, so a construction fund that was comfortably inside a temporary period on the old issue may be measured against a different bond yield afterward.

The private activity analysis travels as well. A refunding issue is generally tested against the property financed by the original issue, so a change of use that occurred years earlier can surface at the refunding rather than at the original closing. Both threads run on the records described in the arbitrage and rebate rules and in the limits on private business use, which is why refundings so often prompt a review of files nobody has opened since construction.

Disclosure at both ends of the transaction

The refunded issue generates an event notice on defeasance, and if the obligations are to be called, a redemption notice as well. The refunding issue generates a new offering document and a new continuing disclosure undertaking, with its own annual date and its own categories of information. Where the refunding retires only part of an issue, the earlier undertaking continues for the balance, so the issuer ends up administering two promises about the same enterprise.

Sequencing matters for the notices themselves. A redemption notice given under the indenture is a different document from the event notice filed with the repository, and the two follow different timetables set by different instruments. Issuers that treat the mailing to registered holders as satisfying the repository obligation leave a gap, and because a defeasance carries no materiality filter, the gap is a plain breach rather than a judgment call that can be defended after the fact.

The offering document for the refunding also has to describe the plan of finance accurately, including what the escrow will and will not do. Statements about the escrow are statements about the security of the refunded obligations as much as the new ones. The framework governing both documents is set out in the official statement and the parties responsible for it, and the promises that follow are described in the continuing disclosure undertaking.
