Why the CMBS tape and the 10-D can disagree
Two SEC filings can cover the same loan in the same period and still print different dollars. That is a data join, not a market call.
Same loan. Same month. Two amounts.
WFCM 2020-C58, loan 25, trust-level securitized ending balance, filing period 2026-07. Rechecked 2026-08-31. Status CONFLICT: the two citations disagree, so there is no canonical basis to pick one.
Two reporters of one period
ABS-EE
the tape
Form ABS-EE Exhibit 102 is the asset data file. For CMBS it is a loan-level XML tape filed with the distribution cycle. Each row is one asset in the pool, with balances, rates, and dates for the report period.
Form 10-D
the remittance
Form 10-D is the distribution report. The trustee files pool facts, certificate activity, and often a loan-level remittance schedule for the same period. It is a second reporter, not a restatement of the tape.
Most mismatches are a bad join
Before you treat two numbers as a fight between filings, check whether you compared the same field. These are the traps we keep hitting in the confirmation ledger.
Trust piece vs whole loan
A CMBS trust often holds only part of a loan. Pari passu companions, B-notes, and mezz sit outside that trust. Both of these filings, when bound correctly, report this trust's piece. Adding the rest of the loan and calling it a filing fight is a join error.
One 10-D column, two tape fields
On many 10-D remittances, the Scheduled Principal column mixes scheduled amortization with unscheduled principal such as curtailments and payoffs. ABS-EE splits those into two fields. Compare the 10-D column to only one tape field and the dollars will not match even when both filings are internally consistent.
Scheduled vs actual
Scheduled collateral is the contract path. Actual collateral is what was paid, including prepayments and shortfalls. Pool totals exist on both bases. Mixing them looks like a conflict. It is two measurements.
The remittance can trail the tape
The 10-D deal snapshot can lag the ABS-EE loan tape for the same labeled period. A payoff or transfer can sit in one file before the other. That is timing, not a vote on which source is better.
Collateral vs certificates
Loan-pool (collateral) balances are not certificate balances. The 10-D talks about both. The tape is about assets. Comparing a bond outstanding figure to a loan ending balance will not reconcile.
Sometimes the bound field still conflicts
The specimen above is already on the same field: this trust's securitized ending balance, not the whole loan. The ABS-EE tape and the 10-D remittance still differ by $74,585.52. We do not pick a winner. We keep both accessions.
Two filings can also agree and both still be wrong about the world. Agreement means the reporters matched each other. It is not a claim that the number is true.
What to show when you have to defend it
- 01
Name the field in one sentence, including grain (this trust vs whole loan) and basis (scheduled vs actual).
- 02
Cite both accessions, even when they match.
- 03
If they do not match, the disagreement is the finding. Do not average them.
Questions
Why would ABS-EE and a 10-D show different balances for the same CMBS loan?
They are two independent SEC filings for the same period. The dollars differ when the fields are not the same thing, when one filing lags the other, or when both bound fields still print different amounts. A live example is WFCM 2020-C58 loan 25 for 2026-07: ABS-EE $9,399,496.50 and 10-D $9,324,910.98.
Which filing is correct when ABS-EE and the 10-D disagree?
Neither filing is chosen as the winner. The work is to name the field, keep both accessions, and treat the disagreement as the finding. Two filings can agree and both still be wrong about the world. Agreement is not a truth claim.
What is the difference between the CMBS tape and Form 10-D?
The tape is Form ABS-EE Exhibit 102, a loan-level asset data file. Form 10-D is the trustee distribution report. They cover the same cycle from different reporters and different grains.
Does a tape vs 10-D mismatch mean the loan is in default?
No. A dual-filing mismatch is a reporting join. Default, special servicing, and delinquency are separate facts, each with their own definition and source.
