Annual ECB statistics add-on, individual insurer (aes)

A regulatory return listed by the European Insurance and Occupational Pensions Authority (EIOPA), European Union.

Official title: Annual ECB reporting Solo

The facts

Who files
Insurance corporations incorporated and resident in a euro area Member State report the ECB's statistical data to their national central bank, directly or through the national supervisor (ECB Regulation 1374/2014, Articles 2 and 4). EIOPA builds the ECB add-ons into its taxonomy so a firm can send one report covering both EIOPA's and the ECB's requirements, subject to its national authority's guidance. Source
How often
Once a year. Source
Deadline
At the latest 14 weeks after the end of the year, to the national central bank or the national supervisor under local arrangements (ECB Regulation 1374/2014, Article 8). EIOPA's taxonomy roadmap gives no deadline for the ECB entry points. Source
Format
XBRL-XML. Firms file in the data exchange formats set by their national supervisor or group supervisor (Implementing Regulation (EU) 2023/894, Article 1). National supervisors send the data on to EIOPA as XBRL 2.1 instance documents built on EIOPA's Solvency II taxonomy (EIOPA decision EIOPA-BoS-21/517, Article 6), following EIOPA's XBRL Filing Rules and applying the taxonomy's validation rules (Article 8).

Listed from taxonomy 2.8.2 Hotfix, in use for 2026 reference dates: the template groups linked from mod/aes-pre.xml, named from tab/tab-lab-en.xml (or the table label where the group label is generic). The 2.8.2 Hotfix release notes (Table 1) count 101 templates. Taxonomy 2.10.0, from the 31 March 2027 reference date, has 93 templates (release notes Table 1: 91); it drops E.02.01.16 (Pension entitlements), S.21.01.01 (Loss distribution risk profile), S.21.02.01 (Underwriting risks non-life), S.21.03.01 (Non-life distribution of underwriting risks - by sum insured), S.22.06.01 (Best estimate subject to volatility adjustment by country and currency), S.23.02.01 (Detailed information by tiers on own funds), S.23.03.01 (Annual movements on own funds), S.29.01.01 (Excess of Assets over Liabilities), S.29.02.01 (Excess of Assets over Liabilities - explained by investments and financial liabilities), S.29.03.01 (Excess of Assets over Liabilities - explained by technical provisions), S.29.04.01 (Detailed analysis per period - Technical flows versus Technical provisions) and adds S.22.07.01 (Calculated volatility adjustment and corresponding best estimates by country and currency), S.27.02.01 (Catastrophe data - Loss data), S.27.03.01 (Catastrophe data - Exposure and premium data). The 2.10.0 release notes say templates 'S.30.01 and S.03.02' (as written) are kept in the taxonomy for ad hoc supervisory requests but are no longer part of the ITS on supervisory reporting. Source

Validation rules

2,512 rules, as counted from the EIOPA's published material. Software can run them exactly as published. Source

How they are written: XBRL Formula 1.0 assertions in the taxonomy package (linked from mod/aes.xsd), listed in an Excel workbook with an 'Expression' column; EIOPA switches rules off between releases through the aes-ignore-val.xml deactivation file..

EIOPA's Guidelines on reporting and public disclosure include the mandatory application of the validation rules published by EIOPA (List of Validations). ERROR rules must pass for a report to be accepted; WARNING rules flag possible errors without blocking the report.

The rules, on dev.eiopa.europa.eu

How they were counted

Rows of sheet 'Business Validation 2.8.2 HF' in EIOPA_SolvencyII_Validations_2.8.2_Hotfix.xlsx (updated 10 November 2026) whose 'Severity and modules' column names aes and whose 'Deactivated' column is 'no': 2,512 (1,709 ERROR, 803 WARNING; 2,378 marked 'Include in XBRL' yes). 46 more rows name aes but are deactivated. For 2.10.0, sheet 'Business Validation 2.10.0' of EIOPA_SolvencyII_Validations_2.10.0.xlsx (last update 30 June 2026) names aes in 2,919 rows (1,650 ERROR, 1,269 WARNING; 2,703 'Include in XBRL' yes), none deactivated.

Counts are in the EIOPA's own unit, so they are not comparable with other regulators' counts.

Public data

Published only added up across firms. The ECB (not EIOPA) publishes balance sheet statistics for euro area insurance corporations from Q3 2016, and annual premiums, claims and acquisition expenses from 2017, in the ECB Data Portal. National central banks derive most of these statistics from Solvency II reporting plus the ECB add-ons. Source
