Cities borrow to build. Water systems, transit, schools, and hospitals are often financed through municipal bonds. Yet the name on a bond does not always tell you who will repay it.
Consider the Dormitory Authority of the State of New York (DASNY), which issues bonds on behalf of hundreds of governmental and non-profit institutions. In an example examined by XBRL US, DASNY is the issuer, while Fordham University is the obligor responsible for repayment.

Finding the issuer tells you who brought the security to market. It does not necessarily tell you whose finances matter when the debt falls due. This article looks at why tracing that responsibility is difficult, and how standardised identifiers, including the Legal Entity Identifier (LEI), could help.
The Issuer and the Obligor
The issuer is the organisation that issues a municipal bond. The obligor, or obligated person, is the party committed to supporting repayment.
In a simple arrangement, one government plays both roles: a city issues bonds and repays them from the revenues named in the bond documents.
In conduit financing, a public authority issues bonds on behalf of a borrower such as a non-profit hospital or university. The authority is the issuer, but the borrower generally makes the payments. An analyst assessing that hospital would need its own financial information and the repayment terms, not just the authority’s statements.
The Municipal Securities Rulemaking Board (MSRB) notes that in conduit financing, the party responsible for repayment is generally identified in the official statement and continuing disclosure agreement.
The practical question is not simply “Who is named on the bond?” but “Whose money is expected to make the payments?” In a conduit issue, a public authority may appear prominently on the cover, while the official statement directs readers to the borrower’s revenues, financial statements and continuing disclosure commitments. That does not make the issuer irrelevant. It means the authority’s legal role and the borrower’s repayment responsibility must be examined separately. A researcher who stops at the name on the cover may end up assessing the wrong organisation.

Why Tracing Responsibility Is Difficult
The MSRB’s Electronic Municipal Market Access system (EMMA) gives public access to official statements and disclosures. The challenge is working out how the organisations named in them relate to a given security.
According to XBRL US, EMMA supports searches by issuer but offers no easy way to search by obligor, so researchers often rely on lengthy PDF official statements. Campbell Pryde, President and CEO of XBRL US, examined this problem in a 2024 paper, Identifying the Obligor for Municipal Securities.
This becomes especially time-consuming when the same borrower appears in more than one financing. A university might have debt issued through different authorities at different times, and the descriptions in individual filings may not use identical names. Searching the issuer field alone would not necessarily bring those transactions together. The analyst must first identify the obligor in each document, then compare the information across issuances. The need is not for another number on the page; it is for a reliable way to establish that records referring to the same entity really do refer to the same entity.
- One bond issue may include several securities.
- One issuer may finance many borrowers, and one obligor may appear in several issuances.
- Some obligations rest on specific revenues rather than an organisation’s full resources.

Four Real Financing Structures
The XBRL US paper uses real financings to show that no single structure fits every case.
| Example | Structure | What must be traced |
| City of Boston | Issuer and obligor; one issuance, several securities | Each security, linked to the same city |
| Salt Lake County, Utah | Sales Tax Revenue Refunding Bonds, repayable solely from pledged revenues | The pledged revenue stream, not just the county |
| Lancaster County Career & Technology Center | Pooled financing for 17 school districts as obligors | Each district and its link to the securities |
| City of Chicago | Bonds for the Water Fund, an enterprise fund of the city | A fund that is not a separate legal entity |
The Chicago case matters for infrastructure finance in particular, because utilities are often run as funds within a city rather than as separate bodies. Across all four, the real goal is to understand which entities and financial activities connect to a security, and in what capacity.
Take the Lancaster County example: listing 17 districts in a single financing does not tell a reader which obligations each district supports. The financing documents are still needed to establish responsibility. A structured dataset could make the participating entities easier to discover, but it would need to record their roles accurately. Chicago’s Water Fund illustrates a different limit: even a perfectly identified city cannot tell an analyst which portion of the city’s activities provides the pledged revenue. In both cases, identification is valuable only when paired with the legal and financial context.

Where Entity Identifiers Fit
Organisation names can be abbreviated, formatted differently or changed, and unrelated bodies can share similar names. A standard identifier reduces that uncertainty.
The LEI is a 20-character code defined by ISO 17442 and part of the Global LEI System. Each LEI links to reference data such as legal name, registered address, jurisdiction and record status, which the Global Legal Entity Identifier Foundation (GLEIF) publishes free of charge in the Global LEI Index.
An LEI is not a security identifier. US municipal securities commonly carry CUSIP numbers:
The relationship between the two comes from the financing documents. An LEI does not show who must repay a bond, says nothing about creditworthiness, and cannot by itself identify a fund within a city. In the XBRL US model, such a fund is linked to its government’s LEI.

How Structured Data Could Help
In the XBRL US model, machine-readable data using XBRL (eXtensible Business Reporting Language) could link a security’s CUSIP to the issuer’s LEI and the obligor’s LEI, flag pledged revenues, and connect an enterprise fund to its government. A researcher could then trace every security tied to a university or hospital through identifiers, instead of reading documents line by line.
The LEI establishes who an entity is; structured data describes how it relates to securities and financial facts. This remains a proposal, not a description of how EMMA works today.

The Current Regulatory Picture
Under MSRB Form G-32, underwriters provide the LEI of obligated persons other than the issuer, and of credit enhancers, when it is readily available. The MSRB describes that as easily obtainable through a general internet search. This is not a rule requiring every issuer or borrower to obtain an LEI.
Under the Financial Data Transparency Act of 2022, nine federal financial agencies adopted a joint rule establishing common data standards, including the LEI for entity identification. It took effect on October 1, 2026, but does not itself change any reporting requirements; each agency must act further before the standards apply.

A Practical Approach for Researchers
- Find the security by CUSIP, or by issuer and issue description, and locate the official statement on EMMA.
- Read the financing structure to identify the issuer and any separate obligor.
- Note pledged revenues or funds that repayment depends on.
- Check the legal entities in the GLEIF LEI search, comparing legal name, jurisdiction and address with the bond documents.
- Read the record status. A lapsed LEI means the reference data has not been renewed on time, not that the organisation has stopped operating.
An LEI is never proof that an entity guarantees or must repay a bond. That conclusion must come from the financing documents.
In practice, a simple evidence log can make this process more reliable. For each bond, record the security identifier, issuer’s legal name, any named obligor, repayment source and the page of the official statement where each fact appears. If an LEI is available, add it alongside the entity name and note the date on which the record was checked. Where a name match is uncertain, mark it as unresolved rather than guessing. This approach creates an auditable trail: another researcher can see both the identifier and the document supporting the conclusion. It is also useful when records are reviewed months later and an LEI’s reference-data status may have changed.
What This Means for Cities
A water utility funded by user charges, a hospital financed through a conduit issuer and a city borrowing for general purposes may share one market, but not one repayment structure. Clearer identification should make those differences visible. Researchers could compare borrowing across cities and years, investors could find securities tied to the same obligor, and public finance authorities could reuse consistent data across reports.
The same question arises wherever public authorities, special purpose vehicles or public-private arrangements finance urban infrastructure. Still, standardisation does not replace analysis: repayment always depends on the bond’s legal terms, disclosures and underlying revenues.

Conclusion
Understanding city debt means looking past the issuer’s name to the borrower, the obligated bodies and the revenues behind a bond. LEIs, combined with security identifiers and structured data, offer a consistent way to connect these parties. The goal is not more identifiers for their own sake, but urban finance data that makes clear who issued a bond, who repays it, and which financial information belongs to each.
