## The data
You can't see the data, but you can query it. It is in DuckDB, in the tables below. Write DuckDB SQL.
To run queries, reply with one or more fenced blocks (```sql), and nothing else is needed:
each is run and its results sent back to you. You have up to 8 rounds of queries.
When you have what you need, reply with the final answers and no queries.
All columns are text (VARCHAR); dates are ISO strings.
- `entities` (16 rows): entity_id, name, lei, country, entity_type, parent_id, ultimate_parent_id, record_ids
- `instruments` (8 rows): instrument_id, description, issuer_id, guarantor_id, credit_risk_of, seniority, currency, local_currency, maturity
- `ratings` (41 rows): rated_id, rating_type, ccy_basis, rating, outlook, watch, action, valid_from, valid_to, action_id
- `ceilings` (2 rows): country, ceiling, valid_from
- `ancestors` (4 rows): entity_id, ancestor_id, levels_up
These tables are the data after its rules have been applied: duplicate records merged into one entity (record_ids lists the records each entity merges), and each rating with the period it held. An empty valid_to means the rating was still in force on 1 October 2026. ancestors lists every entity above each entity in its chain of parents, with how many levels up.
## Questions
Answer each question below from the data above. Start each answer on a new line with its
number in bold, like **Q1.**, give the direct answer first, then at most two sentences of
reasoning that cite the records (IDs) you relied on.
Then end with one JSON block (```json) holding the structured answer to each question listed
here, with exactly these fields, shaped like {"Q1": {"field": value}, ...}. Name entities by their record ID: the entity_id in the CSV files, or the part of the IRI after lad: in the RDF (E01, not Kestrel Energy plc).

**Q1.** A-. E01's foreign-currency issuer rating on 2025-01-01 was A- (A01, valid 2024-03-12 to 2025-06-20).
**Q2.** No. E01's only 2026 action was an affirmation with the outlook moved to Negative (A03, 2026-02-10); the downgrade to BBB was in 2025 (A02).
**Q3.** No. The 2031 note I02 is rated BB+ since 2025-06-20 (A07), which is below investment grade.
**Q4.** Positive. E02's current rating action is A09, with outlook POS.
**Q5.** E02 (Northwind Holdings), the guarantor of I03. I03 is rated A (A11).
**Q6.** Valdoria's Country Ceiling is BB (VD, from 2025-04-01), and E05's foreign-currency rating is BB (A14). Its local-currency rating is BBB- (A13). That ceiling is the likely cause, but the data doesn't state the reason explicitly.
**Q7.** E08 and E10. E08 was downgraded in 2026 (A21, A22) and E10 on 2026-04-15 (A27). E06's Rating Watch Negative (RWN) is not a downgrade.
**Q8.** E08. Its rating is RD from 2026-07-08 (A22), still in force.
**Q9.** 12. Current non-withdrawn issuer ratings are held by CV, E01, E02, E05, E06, E08, E09, E10, E12, E13, E14 and E15. E07's was withdrawn (A19).
**Q10.** Depends. E05 is BB in foreign currency (A14, sub-investment grade) but BBB- in local currency (A13, investment grade).
**Q11.** BBB+. E14 on 2025-06-01 was BBB+ (A36, from 2024-09-30).
**Q12.** A-. E14 on 2024-01-01 was A- (A34).
**Q13.** 1. The only downgrade is A36 (2024-09-30).
**Q14.** None. E12's first rating (A30) starts on 2024-02-01.
**Q15.** A-. E10 (which merges E17) was A- on 2026-01-01 (A26).
**Q16.** No. E14 was BBB+ on 2025-01-01 and is BBB+ now (A33), though it passed through a watch period (A35).
**Q17.** No. E06 stayed at A- and was placed on Rating Watch Negative (A17), which is not a downgrade.
**Q18.** E06 (A17).
**Q19.** E01 and E09 (A03, A25).
**Q20.** No. E07's rating was withdrawn (A19), not moved to a default grade, so there is no default record.
**Q21.** E07. Its rating was withdrawn on 2026-05-12 (A19).
**Q22.** E08, which reached RD (A22).
**Q23.** F2 (A04).
**Q24.** Yes. E01's issuer rating is BBB (A03).
**Q25.** 5. The investment-grade instruments are I01 (BBB), I03 (A), I05 (BBB+), I06 (A-) and I07 (BBB-).
**Q26.** A+ (A40).
**Q27.** A- (I06, A42).
**Q28.** BBB+ (CV, A38).
**Q29.** None. VD has no rating rows.
**Q30.** E05 and E15. E05 is BB against VD's BB ceiling, and E15 is A against CV's A ceiling.
**Q31.** No. E05 and E15 are exactly at their ceilings, not above.
**Q32.** E09.
**Q33.** E10, the guarantor of I05. I05 is rated BBB+ (A29).
**Q34.** No. E12 has no parent, while E10's ultimate parent is E09.
**Q35.** 3: E09, E10 and E11.
**Q36.** 2: E02 and E04.
**Q37.** 16. The entities table has 16 rows after duplicates were merged.
**Q38.** No. E06 and E13 are separate entities with different LEIs and countries (DE and US).
**Q39.** A (A09).
**Q40.** 5. The GB issuers with a current issuer rating are E01, E02, E09, E12 and E14. E07 is excluded because its rating was withdrawn.
**Q41.** None. Brindle Capital is not in the data.
**Q42.** LU.
**Q43.** 1: E10.
**Q44.** Yes. I07 has local_currency = yes and is denominated in XVD.
**Q45.** No. The ceiling caps foreign-currency ratings, and I07 is a local-currency obligation rated BBB- (A45). I'm assuming the ceiling applies only to foreign currency, which the data doesn't state.
**Q46.** No. Only its instrument I05 is rated; E11 has no issuer rating rows.
**Q47.** None. I08 has no rating.
**Q48.** 7. I01 to I07 are rated, and I08 is not.
