As of 1 October 2026, how many distinct issuers hold an issuer rating?

Tests: Everything at once: identity, withdrawal, instrument versus issuer, ceiling versus rating.

Expected: count = 12

✅ R1 csv run 1 graded by code

12. Entities with an active LTIDR rating on 1 Oct 2026 are E01, E02, E05, E06, E08, E09, E10, E12, E13, E14, E15, E16. E03 is excluded as a duplicate of E02, E07 was withdrawn (A19), and E11's CO-type rating is not an LTIDR.

❌ R1 csv run 2 graded by code

13. Counting distinct issuers with an LTIDR (A-rated and others): E01, E02, E05, E06, E08, E09, E10, E12, E13, E14, E15, E16, and the sovereign CV. E03 duplicates E02 by LEI, and E11 has only a CO rating, which is excluded here.

JSON: {"count": 13}

Why: count: expected 12, got 13

❌ R1 csv run 3 graded by code

13. The 13 distinct issuers with LTIDR/STIDR ratings are E01, E02 (E03 is the same LEI), E05, E06, E08, E09, E10 (E17 is the same LEI), E12, E13, E14, CV, E15, and E16. E04, E07 (withdrawn, A19), E11 (only a CO rating), E17, and VD (only a CC rating) are excluded.

JSON: {"count": 13}

Why: count: expected 12, got 13

❌ R1 csv run 4 graded by code

13. The entities holding a current LTIDR are E01, E02/E03 (one entity, shared LEI), E05, E06, E08, E09, E10, E12, E13, E14, CV, E15 and E16. E07 was withdrawn (A19), and E04, E11, E17 and VD have no LTIDR.

❌ R1 csv run 5 graded by code

13. Counting distinct LEIs, E01, E02/E03, E05, E06, E08, E09, E10, E12, E13, E14, CV, E15 and E16 hold LTIDRs. E07 is withdrawn (A19), and E04, E11, VD and E17 have no LTIDR. Counting CV, a sovereign, is a judgment call.

❌ R2 rdf run 1 graded by code

13. Fourteen records hold an issuer rating on that date, but E02 and E03 share an LEI and are one entity. The count excludes E11 (type CO, see Q46), E07 (withdrawn), and VD (country ceiling only).

13. E01, E02, E05, E06, E08, E09, E10, E12, E13, E14, E15, E16 and CV hold LTIDR/STIDR ratings; E03 duplicates E02's LEI, so it is not counted again.

The issuers holding a long-term or short-term issuer rating (LTIDR/STIDR) on 1 October 2026 are E01, E02, E03, E05, E06, E08, E09, E10, E12, E13, E14, E15, E16, and CV. E07 was withdrawn (A19), and E11's only rating is type CO, which I do not count as an issuer rating.

Why: count: expected 12, got 14

❌ R2 rdf run 4 graded by code

13. Taking the latest actions, the entities with an issuer-type (LTIDR) rating are E01, E02/E03, E05, E06, E08, E09, E10, E12, E13, E14, E15, E16 and CV. E02 and E03 share an LEI, so I counted them once; by record it is 14.

The count is E01, E02, E05, E06, E08, E09, E10, E12, E14, E15 and the Republic of Corvenia (CV). I counted E08's RD as a rating, since it is a point on the scale. I excluded E07 (withdrawn, A19), E11 (only a credit opinion, A46), Valdoria (only a Country Ceiling), E13 (no actions), and the QA record E16.
