### ontology.md (the vocabulary the data uses)

# Credit ratings: a teaching ontology

Entities, instruments, rating actions and the codes the data uses, each with a definition that states what it means and how to read it. Invented for an experiment; not a model of any real rating agency.

## Classes

### Entity

A legal entity: a company, bank, finance subsidiary or sovereign. An entity is identified by its LEI (LEI), not by its name or record ID. The data holds records from more than one source system (source system), so the same entity can appear as several records with different IDs and differently spelled names: two records with the same LEI are the same entity, and every fact recorded against either record is a fact about that one entity.

### Instrument

A debt instrument, such as a bond or note, issued by an entity (issuer). An instrument's rating is not the issuer's rating: it can sit above or below it depending on seniority (seniority) and on any guarantee (guarantor).

### Rating action

Something a rating agency did to a rating on a date (date): assigned, affirmed, upgraded, downgraded, placed on Watch or withdrawn it. Each action applies to one rated thing (rated thing), one rating type (rating type) and, for issuer ratings, one currency basis (currency basis). A rating holds from its action date until the next action on the same thing, type and basis: so the rating on a date D is the one set by the latest action on or before D, and the current rating is the latest action overall. rating always holds the rating as it stands after the action, including when it did not change.

## Properties

### name (CSV column `name`)

The name as the source system spells it. Names are not identifiers: the same entity can be spelled differently in different systems.

### LEI (CSV column `lei`)

Legal Entity Identifier: the identifier that says which legal entity a record describes. Same LEI, same entity. Sovereigns have none.

### country (CSV column `country`)

ISO-style code of the country where the entity is domiciled. Where an entity's records disagree, see source system for which holds. It decides which Country Ceiling, if any, applies to the entity's foreign-currency ratings. VD is the Republic of Valdoria and CV the Republic of Corvenia (both invented).

### entity type (CSV column `entity_type`)

What kind of entity it is: a concept of the scheme Entity types.

### parent (CSV column `parent_id`)

The entity that owns and controls this one. A parent link names a record, but points at the entity that record describes, so the chain continues from any of that entity's records. Following parents up to an entity with no parent gives the ultimate parent; a group is an ultimate parent and every entity whose chain of parents ends at it.

### source system (CSV column `source_system`)

The internal system the record comes from (RATINGS, RESEARCH, QA). Each system keeps its own records of the same entities; see Entity. Where records of the same entity disagree, which one holds depends on the field. RATINGS is the system of record for names and parent links. Domicile is the exception: the RESEARCH team checks each entity's registered office against its filings, so where records disagree on country, the RESEARCH record holds. QA records are test data, created to check the systems: they describe no real entity, so a QA record, and every action recorded against it, must be ignored.

### description (CSV column `description`)

The instrument's name: issuer, coupon and maturity year.

### issuer (CSV column `issuer_id`)

The entity that issued the instrument and owes the payments. Not necessarily the entity whose credit risk the investor takes: see guarantor.

### guarantor (CSV column `guarantor_id`)

An entity that guarantees the instrument's payments if the issuer does not pay. A guaranteed instrument carries the guarantor's credit risk, so it is rated in line with the guarantor's issuer rating, not the issuer's.

### seniority (CSV column `seniority`)

Where the instrument ranks in repayment if the issuer fails: a concept of the scheme Seniorities.

### currency (CSV column `currency`)

The currency the instrument pays in, as an ISO 4217 code, or one of two local codes: XVD, the Valdorian dollar, the domestic currency of VD; and CVK, the Corvenian krone, the domestic currency of CV. Debt in a currency other than the domestic one of the issuer's country is exposed to that country's transfer and convertibility risk: see Country Ceiling (CC). Debt in the domestic currency is local-currency debt and is not capped by the ceiling.

### maturity (CSV column `maturity`)

The date the instrument is due to be repaid.

### date (CSV column `date`)

The date the action took effect.

### rated thing (CSV column `rated_id`)

What the action is about: an entity (for issuer ratings and Country Ceilings) or an instrument (for instrument ratings).

### rating type (CSV column `rating_type`)

Which kind of rating the action concerns: a concept of the scheme Rating types. Different types are different ratings and are never compared or combined with each other.

### currency basis (CSV column `ccy_basis`)

For issuer ratings, whether the rating covers foreign-currency (FC) or local-currency (LC) obligations: a concept of the scheme Currency bases. An entity can have both, with different values.

### action (CSV column `action`)

What was done: a concept of the scheme Action types. Only upgrades and downgrades change a rating.

### rating (CSV column `rating`)

The rating after the action, on the scale of its rating type. Long-term scale, strongest to weakest: AAA, AA+, AA, AA-, A+, A, A-, BBB+, BBB, BBB-, BB+, BB, BB-, B+, B, B-, CCC, CC, C, RD, D. Investment grade means BBB- or higher; BB+ and below is speculative grade (high yield). RD (restricted default) means the issuer has defaulted on some material obligations, for instance by completing a distressed debt exchange, without being wound up: RD is a default. D means a general default. Short-term scale, strongest to weakest: F1+, F1, F2, F3, B, C, RD, D. WD means the rating was withdrawn (see Withdrawn (WD)): it is not a point on either scale.

### outlook (CSV column `outlook`)

The likely direction of a long-term rating over the next one to two years: a concept of the scheme Outlooks. An outlook is not a rating: revising it does not change the rating.

### rating watch (CSV column `watch`)

Set when the rating is on Rating Watch: a concept of the scheme Rating Watches. A Watch is not a rating change.

### comment (CSV column `comment`)

The analyst's note on the action, such as the reason for a withdrawal.

## Codes

The codes as they appear in the data, grouped by list.

### Rating types

- **LTIDR**, Long-term Issuer Default Rating: The issuer's own creditworthiness: how likely it is to default on its obligations, on the long-term scale. This is what people usually mean by an entity's rating. The foreign-currency (FC) one is the headline rating; there may also be a local-currency (LC) one.
- **STIDR**, Short-term Issuer Default Rating: The issuer's ability to meet obligations falling due within about a year, on the short-term scale (F1+ to D). Not comparable with long-term ratings.
- **INST**, Instrument rating: The rating of one specific instrument. It starts from the issuer's long-term rating and is notched for the instrument's seniority and expected recovery: subordinated debt is usually rated below the issuer, and guaranteed debt is rated on the guarantor. An instrument rating is never the rating of the issuer.
- **CC**, Country Ceiling: Not a rating of anyone. A cap, set for a country, on the foreign-currency ratings of entities domiciled there and of their foreign-currency debt. It reflects transfer and convertibility risk: the risk that the government stops money being converted or sent abroad, so even a sound company could not pay foreign-currency debt. Foreign-currency ratings of entities in the country are generally no higher than the ceiling; local-currency ratings are not capped. A Country Ceiling is not the sovereign's own issuer rating.
- **CO**, Credit opinion: A private, point-in-time view of an entity's credit, given to one client. It is not a published rating and not an issuer rating: never count it as a rating, and never report its value as the entity's rating.

### Currency bases

- **FC**, Foreign currency: Covers obligations in foreign currency, so it is subject to the Country Ceiling.
- **LC**, Local currency: Covers obligations in the currency of the entity's own country; not subject to the Country Ceiling.

### Action types

- **AS**, Assigned: A first rating is given.
- **AF**, Affirmed: The rating is reviewed and kept the same. The outlook may be revised in the same action; that does not make it an upgrade or a downgrade.
- **UG**, Upgraded: The rating is raised.
- **DG**, Downgraded: The rating is lowered. The only action that counts as a downgrade.
- **RW**, Placed on Rating Watch: The rating is flagged as likely to change soon, usually within about six months, in the direction rating watch gives. The rating itself is unchanged: not a downgrade.
- **WD**, Withdrawn: The agency stops maintaining the rating, often for commercial reasons (the issuer no longer pays for it, or the debt is repaid). After a withdrawal the entity has no rating of that type. A withdrawal is not a credit event: it says nothing about default, and is not a downgrade.
- **EX**, Expected rating: A rating signalled before an instrument's final documents are signed. It is not yet a rating: the instrument stays unrated until an Assigned (AS) action confirms it.

### Outlooks

- **STA**, Stable: No direction expected.
- **POS**, Positive: The rating may go up over one to two years.
- **NEG**, Negative: The rating may go down over one to two years. Not a downgrade.

### Rating Watches

- **RWN**, Rating Watch Negative: A downgrade is likely in the near term. Not a downgrade yet.

### Seniorities

- **SU**, Senior unsecured: Ranks with the issuer's ordinary debts; usually rated at the level of the issuer's long-term rating.
- **SUB**, Subordinated: Repaid only after senior debt, so investors recover less in a default; usually rated one or more notches below the issuer's long-term rating.

### Entity types

- **CORP**, Corporate: A non-financial company.
- **BANK**, Bank: A bank.
- **FINSUB**, Finance subsidiary: A subsidiary that exists to raise debt for its parent group. It usually has no issuer rating of its own; its debt is guaranteed by the parent, so investors take the parent's credit risk.
- **SOV**, Sovereign: A national government. A sovereign record can carry a Country Ceiling, issuer ratings, or both: they are different things, and the ceiling is not the sovereign's rating.

The model
**Q1.** A-. E01's LTIDR was A- (A01, 2024-03-12) until it was downgraded to BBB on 2025-06-20 (A02).

**Q2.** No. E01's only 2026 action was an affirmation with a Negative outlook (A03), which is not a downgrade.

**Q3.** No, it is BB+. I02 is subordinated, and its rating was cut to BB+ by A07.

**Q4.** Positive. E02 and E03 share an LEI and are the same entity. The latest action is E03's affirmation, A09 (2025-09-15), with a POS outlook.

**Q5.** The holder takes E02's credit risk, since E02 guarantees I03. I03 is rated A (A11).

**Q6.** Not in the JSON. E05's foreign-currency rating is BB (A14) and its local-currency rating is BBB- (A13). The BB Country Ceiling for VD (A12) caps the foreign-currency rating, while the local-currency rating is not capped.

**Q7.** 38 issuers had a downgrade in 2026 (action DG on the issuer rating), listed in the JSON. They include E08, E10 and E5019.

**Q8.** E08 only, rated RD from 2026-07-08 (A22).

**Q9.** 377. This counts distinct LEIs (or IDs, for sovereigns) whose latest long-term issuer action on or before 2026-10-01 is not a withdrawal, excluding QA records.

**Q10.** Depends. E05 is BB on foreign currency (speculative) and BBB- on local currency (investment grade).

**Q11.** BBB+. E14 was downgraded by A36 on 2024-09-30.

**Q12.** A- (A34).

**Q13.** 1. Only A36 is a downgrade; the RW and AF actions are not.

**Q14.** None. E12's first rating (A30) was assigned on 2024-02-01.

**Q15.** A- (A26). The downgrade to BBB+ (A27) came on 2026-04-15.

**Q16.** No. The rating stayed BBB+ throughout, and the later actions were a watch and an affirmation.

**Q17.** No. E06 only had a Rating Watch (A17), with the rating still A-.

**Q18.** 32 issuers, listed in the JSON. Their latest action on or before 2026-10-01 carries an RWN watch, including E06 and E1006.

**Q19.** 47 issuers, listed in the JSON. I excluded those whose latest action was a withdrawal. I also excluded E1132 and E1146, whose latest action is a watch with no outlook, though this is a judgement call.

**Q20.** No. E07's rating was withdrawn for commercial reasons (A19), which is not a default.

**Q21.** 36 entities, listed in the JSON. Each one's latest issuer action is a withdrawal, including E07. I left out E1106, which was withdrawn on local currency only and still has a foreign-currency rating.

**Q22.** Only E08. It is the only non-QA record with an RD or D rating.

**Q23.** F2 (A04).

**Q24.** Yes. E01's rating is BBB (A03).

**Q25.** 72. I counted instruments whose latest rating, ignoring withdrawn or expected-only ones, is BBB- or better. Of 113 rated instruments, 72 qualify.

**Q26.** A+ (A40).

**Q27.** A- (A42).

**Q28.** BBB+ (A38).

**Q29.** None. VD only has a Country Ceiling (A12), which is not an issuer rating.

**Q30.** 13 entities, listed in the JSON. These are entities whose foreign-currency rating equals the ceiling: A for CV and BB for VD. Domicile follows the RESEARCH record where records disagree.

**Q31.** No. No entity's foreign-currency rating is above A in CV or above BB in VD.

**Q32.** E09. The chain is E11 to E10 to E09.

**Q33.** The holder takes E10's credit risk, since E10 guarantees I05. I05 is rated BBB+ (A29).

**Q34.** No. E12 has no parent and is not in the E09 group.

**Q35.** 3: E09, E10 and E11. E17 is a duplicate record of E10.

**Q36.** 2: E02 and E04. E03 is the same entity as E02.

**Q37.** 497, counting distinct LEIs (or IDs where there is no LEI) and excluding QA records.

**Q38.** No. Their LEIs differ.

**Q39.** A (A08 and A09).

**Q40.** 79. Country follows the RESEARCH record where records disagree.

**Q41.** None. E16 is a QA record, so it is ignored.

**Q42.** LU. The RESEARCH record (E17) holds for domicile, although the RATINGS record E10 says DE.

**Q43.** 1. Only E17, which is the same entity as E10, is in LU.

**Q44.** Yes. I07 is in XVD, VD's domestic currency.

**Q45.** No. I07 is local-currency debt, so it is not capped by the ceiling.

**Q46.** No. E11 only has a credit opinion (A46), which is not a rating.

**Q47.** None. I08 only has an expected rating (A47), so it stays unrated.

**Q48.** 113 instruments held a rating on 2026-10-01.

**Q49.** E5001. The chain runs E5047, E5035, E5023, E5011, E5167 (the same entity as E5005), E5002, E5001.

**Q50.** 6 levels.

**Q51.** 58, counting by LEI so duplicate records are not double-counted.

**Q52.** 19. I excluded the Belir branch, because RESEARCH's parent link on E5168 conflicts with RATINGS, which holds for parent links.

**Q53.** No. E5062's RATINGS parent chain leads to E5059 (Belir Group), not Rotam.

**Q54.** E5106 and E5124 and E5130. E5106 is Wonod Steel BV, and its RESEARCH record E5169 places it in VD.

**Q55.** 31. These are rated entities that have at least one VD-domiciled entity above them in their chain of parents.

**Q56.** BB-, held by E5144.

**Q57.** E5002. E5011 reaches it via E5167 (the same entity as E5005), and E5013 reaches it via E5006.

**Q58.** E5145. It guarantees I5007, which was issued by E5133 in the Vesol group.

**Q59.** 12.

**Q60.** The holder takes E5145's credit risk. It is not in the same group as the issuer: E5133 belongs to the Vesol group and E5145 to the Geren group.

**Q61.** 19.
