TL;DR
No stable public deal document was located in this review that supports the previous issuer volumes, pool shares, APR ranges, fees, backup-servicer timing, 90/5/5 capital stack, enhancement percentages, trigger effects or rating gaps. Those values are removed. Auto-loan ABS mechanics must be reconstructed from a named transaction’s receivable eligibility, servicing agreement, accounts, priority of payments, enhancement, triggers and rating report.

1. Transaction parties
JCR’s general structured-finance methodology supports the following party-risk checklist.
| Role | Required named-deal evidence | Unsafe shortcut |
|---|---|---|
| Originator | Sale / trust documents and pool cutoff | Brand or group name |
| Servicer | Servicing agreement and collection-account terms | Assuming originator and servicer are identical |
| Backup servicer | Appointment, activation event and transition plan | A standard bank or fixed activation period |
| Issuer / trustee | Legal documents | Assuming GK-TK or trust by asset class |
| Arranger / rating agency | Offering document and dated rating action | Dealer or agency “typicality” |
2. Pool composition
JCR’s methodology library provides the analytical categories in the following table; values require the named pool report.
| Field | Evidence to capture |
|---|---|
| Receivable type | Loan, installment sale or lease and governing contract |
| New / used vehicle | Pool stratification and cutoff date |
| APR and remaining term | Weighted measures plus ranges and exclusions |
| Seasoning | Origination date distribution |
| Concentrations | Model, dealer, geography and obligor fields actually disclosed |
3. Interest waterfall
JCR’s general methodology supports review of the following cash-flow fields, not a universal priority.
| Waterfall field | Required evidence |
|---|---|
| Available interest | Contractual definition and account |
| Senior expenses | Named fees and priority |
| Note interest | Class-by-class priority, deferral and shortfall treatment |
| Reserve / OC | Target, floor, release and replenishment mechanics |
| Residual | Conditions for payment and trapping |
4. Principal waterfall
JCR’s general methodology supports the following principal-allocation checklist.
| Field | Required evidence |
|---|---|
| Available principal | Collections, recoveries and asset-sale proceeds included |
| Allocation | Sequential, pro rata or hybrid formula in the documents |
| Trigger switch | Exact metric, threshold, cure and permanence |
| Loss allocation | Class order and write-down / reimbursement terms |
| Amortization | Legal maturity, expected life assumptions and call terms |
5. Credit enhancement
JCR’s methodology library supports identifying the following enhancement forms; sizing is transaction-specific.
| Enhancement | Evidence required |
|---|---|
| Subordination | Closing class balances and loss priority |
| Overcollateralization | Initial / target amount and build or release formula |
| Reserve | Funding source, permitted uses and floor |
| Excess spread | Contractual calculation after fees and losses |
| External support | Legally enforceable amount, provider and termination terms |
6. Performance triggers
JCR’s general methodology supports the following trigger-reading controls.
| Control | Required evidence |
|---|---|
| Metric | Exact numerator, denominator and observation period |
| Threshold | Transaction document value |
| Consequence | Waterfall, replenishment, reserve or amortization change |
| Cure | Cure period and reversibility |
| Reporting | Dated trustee / servicer value |
7. Issuance and rating
JSDA’s securitization-market survey and the named agency action support the following evidence table.
| Claim | Required public source |
|---|---|
| Issuance amount | Dated transaction or JSDA table with category definition |
| Shelf / repeat status | Dated series history |
| Class rating | Named class, agency and action date |
| Agency comparison | Same class and date under each agency’s own criteria |
| Spread | Named pricing result and benchmark convention |
8. Deferred claims
The prior numerical tables are specifically deferred because no public named deal document was identified that supported all their rows. A future update may restore a value only with its transaction, cutoff / pricing date, definition and direct public link.
