Aon Center
200 EAST RANDOLPH STREET · Chicago, IL 60601
Every loan the CMBS tape reports against this building, as each trust filed it. A
building is the grain here, not the loan: this one is collateral in
3 separate trusts,
and the slices below are the pieces of its debt, not four different buildings.

Where the filings differ
Each trust describes the building in its own filing, and these are the fields on
which they do not match. Both spellings are printed with the trust that filed each. Often both
are true — a building sits in one municipality and takes its mail in another — and
where one is simply a misspelling, we do not have a basis to say which.

The asset-level exhibit names up to three tenants per
slice; where the trusts name different ones, all of them are listed.
- Built from SEC Regulation AB II asset-level filings (Form ABS-EE, Item 1(a) exhibits) as filed by each trust’s depositor. Latest filing on this building: 2026-08-31.
- Rebuilt nightly. A slice that left its pool is excluded by the tape’s own latest-filing cut, so this page shows live debt only.
- “Aon Center” is the name used in the offering document (Form 424B2); it is shown only where the filing’s own state matches this building’s.
- Figures are as each trust filed them and are not restated, reconciled or scored here.
