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
8 separate trusts,
and the slices below are the pieces of its debt, not four different buildings.

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.
- Figures are as each trust filed them and are not restated, reconciled or scored here.
