Standing
as of Sep 12, 2026What the public record shows about this issuer’s disclosure practice. Compiled from the MSRB’s EMMA and from award letters governments record themselves. MuniPro confers no credential and issues no rating.
Credentials on record
Conferred by GFOA, recorded from the award letter. Never inferred.
Certificate of Achievement for Excellence in Financial Reporting
No receipt on file
Distinguished Budget Presentation Award
No receipt on file
Popular Annual Financial Reporting Award
No receipt on file
Nothing recorded here means nothing has been recorded — not that an award was withheld.
Dated obligations
Filings a law or contract puts a date on.
Not measured
MuniPro does not hold this issuer’s own continuing-disclosure undertaking date, so no filing is called late here. Why →
Record quality
Disclosure practice — not an assessment of creditworthiness.
Annual reporting compiled
0 of 5
0 of 5 reporting years (2021–2025) have an annual financial filing compiled from the MSRB’s EMMA. The denominator is MuniPro’s 5-year reading window — it is NOT a filing obligation, and a missing year here means no filing was compiled, not that one was owed and skipped.
Record freshness
Within the past year
The newest continuing-disclosure filing MuniPro has compiled for this issuer was posted 16 days ago. This is the age of the public record — it is not a lateness claim, because MuniPro does not hold the date this issuer’s undertaking sets.
Filing timeliness
Not measured
Timeliness needs the date this issuer’s own continuing-disclosure undertaking sets. MuniPro does not hold it, and will not substitute a generic interval.
Standing describes disclosure practice — not an assessment of creditworthiness. It is not a rating, a rank against other governments, or a MuniPro credential. See the full computation →
