## 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` (19 rows): entity_id, name, lei, country, entity_type, parent_id, source_system
- `instruments` (8 rows): instrument_id, description, issuer_id, guarantor_id, seniority, currency, maturity
- `rating_actions` (47 rows): action_id, date, rated_id, rating_type, ccy_basis, action, rating, outlook, watch, comment

## 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).

The model 
**Q1.** A-. Kestrel's LTIDR was A- from A01 (2024-03-12) until the downgrade to BBB in A02 on 2025-06-20.

**Q2.** No. In 2026 Kestrel only had affirmations (A03, A04), with the outlook moved to Negative.

**Q3.** No. The 2031 note (I02, subordinated) was cut to BB+ in A07, which is below investment grade.

**Q4.** Positive. E03 "NORTHWIND HLDGS" has the same LEI as E02, so I treated it as a duplicate record of the same entity. Its latest action, A09 (2025-09-15), affirmed A with a POS outlook, which is more recent than A08.

**Q5.** The holder takes the credit risk of E02, the guarantor of I03, which is rated A. The issuer is E04, but E02 guarantees the notes.

**Q6.** The data points to the Valdoria Country Ceiling (A12), which is BB. Valdoria Telecom's foreign-currency rating is BB (A14), while its local-currency rating is BBB- (A13). The data does not state the reason explicitly.

**Q7.** E08 (A21, A22), E10 (A27) and E16 (A44) were downgraded in 2026. E06's action (A17) was a watch, not a downgrade.

**Q8.** E08. A22 moved it to RD on 2026-07-08, and nothing later changes that.

**Q9.** 13. These are E01, E02 (E03 is a duplicate), E05, E06, E08, E09, E10 (E17 is a duplicate), E12, E13, E14, E15, E16 and CV. E07's rating was withdrawn, E11 has only a credit opinion (CO), and VD has only a country ceiling.

**Q10.** Depends. Its local-currency rating is BBB- (investment grade) and its foreign-currency rating is BB (not investment grade).

**Q11.** BBB+. A36 downgraded it from A- on 2024-09-30.

**Q12.** A-, from A34 (2023-01-15).

**Q13.** 1, from A36. The later actions A35 and A33 are a watch and an affirmation.

**Q14.** None. Halden Foods' first rating, A30, is dated 2024-02-01.

**Q15.** A-. A26 assigned it in 2023, and the downgrade to BBB+ (A27) came on 2026-04-15, after this date.

**Q16.** No. It was BBB+ on 2025-01-01 and is still BBB+ (A33). Only the watch (A35) and the outlook changed in between.

**Q17.** No. A17 only placed Orrin Bank on Rating Watch Negative, and its rating stayed at A-.

**Q18.** E06. The watch from A17 is still open, whereas E14's watch (A35) was resolved by A33.

**Q19.** E01 (A03) and E09 (A25). E06's watch action carries no outlook.

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

**Q21.** E07, whose rating was withdrawn in A19.

**Q22.** E08, which reached RD in A22.

**Q23.** F2 (A04).

**Q24.** Yes. Its issuer rating is BBB (A03).

**Q25.** 6. By my reading, I01 (BBB), I03 (A), I05 (BBB+), I06 (A-), I07 (BBB-) and I08 (A) are investment grade. I08's action code "EX" is undefined in the data. If it does not count as a held rating, the answer is 5.

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

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

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

**Q29.** None. The Republic of Valdoria has only a Country Ceiling (A12, BB), which is not an issuer rating.

**Q30.** E05 (FC BB, ceiling BB) and E15 (FC A, ceiling A).

**Q31.** No. No company's foreign-currency rating is above its country's ceiling.

**Q32.** E09. E11 has parent E10, and E10 has parent E09.

**Q33.** The holder takes the risk of E10, the guarantor of I05, which is rated BBB+ (A27).

**Q34.** No. E12 has no parent link to E09 or E10, and the shared "Halden" name is not evidence of a group.

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

**Q36.** 2, namely E02 and E04. E03 is a duplicate of E02.

**Q37.** 17. The 19 rows include two duplicates by LEI: E03 duplicates E02, and E17 duplicates E10.

**Q38.** No. They have different LEIs, countries (DE and US) and records (E06 and E13).

**Q39.** A. A08 assigned it, A09 affirmed it, and there has been no change since.

**Q40.** 6, namely E01, E02, E09, E12, E14 and E16. E07 is excluded because its rating was withdrawn.

**Q41.** BB+ (A44). E16 comes from the "QA" source system, so it may be test data.

**Q42.** DE. E10 is the primary record. E17 is a research duplicate that shows LU.

**Q43.** 0. The only LU record, E17, is a duplicate of E10, which is domiciled in DE.

**Q44.** Yes. I07 is denominated in XVD, which I take to be Valdoria's local currency. That code is not defined in the data.

**Q45.** No. The note is rated BBB-, and the BB ceiling applies to foreign-currency ratings, not to a local-currency obligation.

**Q46.** No. E11 has only a credit opinion (A46, CO), not an issuer rating.

**Q47.** A (A47). Its action code "EX" is undefined in the data.

**Q48.** 8. Every instrument I01 to I08 has at least one rating action.
