JCR / R&I Japan securitization rating methodology operating playbook

TL;DR

There is no public basis for a single JCR/R&I “operating playbook” with fixed base-default ranges, 4–6× stress multipliers, 1–2-notch downgrade rules, staff counts, action counts or universal monthly / quarterly surveillance cycles. Treat each agency separately. For a named transaction, record the registered legal entity, the criteria version cited by the rating action, pool and legal assumptions, the actual waterfall, and the dated rating / surveillance report. When a public R&I document is unavailable, defer the R&I conclusion rather than copying JCR assumptions across agencies.

Wiki route

This entry sits under structured-finance index as an evidence-control page. Pair it with JCR / R&I methodology and global-agency comparison. Asset-class pages must cite their own named methodology and transaction evidence.

1. Agency identity

FSA’s current register supports the following identity controls.

Control JCR R&I
Legal entity Use the legal name and registration entry shown by FSA Use the legal name and registration entry shown by FSA
Registration status Verify at the review date Verify at the review date
Ownership Require a current shareholder disclosure Require a current shareholder disclosure
Staffing and annual actions Do not estimate Do not estimate
Methodology Use JCR’s applicable published document Use the applicable public R&I document; otherwise defer

Registration does not establish market dominance, foreign recognition or methodological equivalence.

2. Criteria selection

JCR’s structured-finance methodology library is the control surface for the following criteria-selection table.

Step Required evidence
Identify asset class Named transaction and collateral definition
Select criteria Exact methodology title and revision / effective date
Confirm hierarchy General methodology plus every asset-class or legal supplement cited
Confirm transition Agency notice showing whether old or new criteria govern the rating
Preserve exclusions Scope limitations and transaction-specific departures stated in the report

An asset-class label alone does not prove which criteria version was applied.

3. Assumption record

JCR’s general structured-finance methodology supports a qualitative review framework, not the uncited numerical ranges previously shown.

Assumption category Record from the named report
Pool performance Definition, observation period, exclusions and base case
Defaults / losses Frequency, severity, timing and rating stress, if disclosed
Recoveries Rate, timing, costs and collateral segmentation, if disclosed
Prepayment Scenario and source data, if disclosed
Counterparties Dependency, replacement trigger and remedial mechanics
Legal risk Transfer, perfection, commingling, set-off and segregation analysis

Do not back-solve an agency stress multiplier or enhancement target from an invented “typical” deal.

4. Cash-flow modeling

JCR’s general methodology supports the following transaction-model evidence checklist.

Modeling input Required transaction evidence
Collections Contractual principal / interest schedule and servicing assumptions
Default and recovery Timing curves and loss assumptions disclosed by the agency
Prepayment Named scenarios, not an asset-class stereotype
Interest and currency Actual asset / liability terms and hedge documents
Fees and accounts Contractual priority and amounts
Triggers Exact definitions and resulting waterfall changes
Tranche payment Legal payment priority for the named class

Model outcomes and rating tolerances must come from the agency report; this page does not state a universal “zero shortfall” rule.

5. Surveillance

JCR’s public structured-finance rating list is the starting point for dated rating actions.

Surveillance claim Evidence required
Review frequency Agency policy or named transaction report
Servicer reporting Transaction servicing agreement / report
Performance status Dated trustee, servicer or agency surveillance disclosure
Watch / outlook Dated agency action
Rating change Dated action and published rationale

Do not assume monthly reports, quarterly committees, annual reruns or fixed event-review timing across transactions.

6. Rating-action analysis

JCR’s rating list supports the following action-comparison controls.

Question Safe treatment
What changed? Cite the dated agency rationale
Was a trigger breached? Cite the contractual definition and reported value
How many notches? Record the actual action; do not predict a fixed magnitude
Was the action automatic? Check the criteria and report; never infer from one metric
Did another agency differ? Compare the same tranche and date under its own criteria

7. Reproducible analyst packet

For each transaction, retain:

  1. legal issuer, series and class;
  2. rating agency legal entity and registration check;
  3. rating symbol, date, outlook / watch and action type;
  4. cited criteria title and version;
  5. collateral cut and performance period;
  6. enhancement, waterfall, trigger and hedge terms;
  7. public surveillance evidence;
  8. explicit gaps where documents are not public.

8. Claims removed by this review

  • fixed asset-class default ranges and stress multipliers;
  • fixed recovery timing, downgrade magnitudes and rating timelines;
  • staff and annual-action estimates;
  • ownership / affiliation claims without shareholder evidence;
  • a blanket Japan-vs-global sovereign ceiling or notch gap;
  • universal agency coverage, investor recognition or surveillance cadence.
