SESAMm Methodology Overview

How SESAMm detects ESG controversies and produces the Controversy Exposure Score (CES): the data we use, the AI models we run, and how human expertise shapes them.

Methodology

How we detect ESG controversies and produce the Controversy Exposure Score (CES)
SESAMm's TextReveal® ESG Alerts detects ESG controversies across millions of companies worldwide, with the Controversy Exposure Score (CES) as its regulated ESG rating under Regulation (EU) 2024/3005. The full methodology, covering the rating's scope, data sources, scoring, limitations, conflict-of-interest safeguards and revision process, is available here.

Complaints and Reasoned Concerns Policy

(Complaints Mechanism and Reasoned Concerns, Regulation (EU)
2024/3005)
Object Establishes SESAMm S.A.S.'s complaints-handling mechanism (Article 19) and its channel for reasoned concerns from stakeholders (Article 20), and how each is received, investigated, answered and recorded.
Legal basis Articles 19 and 20 of Regulation (EU) 2024/3005
Approval tier Supervisory Board (Conseil de Surveillance)
Owner Compliance Officer
Status Approved by Supervisory Board
Version v1.0
Classification Public (policy with contact details published on SESAMm's website); records kept internally
This policy sets out the two channels SESAMm S.A.S. operates under Regulation (EU) 2024/3005: a complaints-handling mechanism under Article 19 and a channel for reasoned concerns from stakeholders under Article 20. It is owned by the Compliance Officer and approved by the Supervisory Board. This policy and the contact details for both channels are published on SESAMm's website. It complements, and does not replace, the internal ESG Rating Review, Correction Procedure (data-quality and factual-error corrections) and Anonymous Reporting Procedure (whistleblowing).
1. Scope
The complaints channel (Article 19) is open to users and subscribers of SESAMm's ESG ratings, to rated items and to issuers. It covers complaints about how a rating was produced, whether a rating is representative, and how the methodology was applied to an individual rating, as well as factual errors in the underlying data. The reasoned-concerns channel (Article 20) is open to any stakeholder, including parties who are neither users nor rated, who provides their name and position.
2. How to submit

SESAMm operates two intake routes. Rated items and issuers, and users and subscribers, use the secure portal, reached through the personalised link SESAMm provides, where they can review the relevant data and raise a factual error, a case challenge, or a regulatory or methodology question. Any stakeholder who does not use the portal, including parties who are neither users nor rated such as NGOs or academics, may write to Enable JavaScript to view, providing their name and position. Where a case challenge or factual error is sent by email by a party that has portal access, SESAMm redirects it to the portal so that the matter is logged and addressed in a single place.

3. Complaints handling (Article 19)
SESAMm receives, investigates and keeps records of each complaint. Within the portal, factual errors and case challenges are handled under the internal ESG Rating Review and Correction Procedure, while regulatory and methodology questions are routed to SESAMm's regulatory team. Receipt is acknowledged and the matter is investigated fairly. A complaint about how a rating was produced or whether a rating is representative is reviewed independently of the persons who produced the rating concerned. The outcome and the reasons for it are communicated to the complainant in a timely manner. Disagreement with the methodology itself, where it has been correctly applied to accurate data, is recorded and answered but does not constitute a correctable error.
4. Reasoned concerns (Article 20)

SESAMm receives reasoned concerns from any stakeholder who provides their name and position, in particular at Enable JavaScript to view. Such concerns are logged and, SESAMm not being a small ESG rating provider within the meaning of the Regulation, SESAMm endeavours to reply within 30 working days of receipt.

5. Independence and escalation
Complaints and concerns are handled by the Compliance Officer or by a person not involved in producing the rating concerned, so that no person reviews their own work. Matters that cannot be resolved at that level, or that concern the Compliance Officer, are escalated to the Supervisory Board.
6. Records
Both channels are logged in a register maintained by the Compliance Officer, recording the date, the originator, the subject, the assessment, the outcome and the date of reply. Records are retained for at least five years and feed the annual compliance report to the Supervisory Board.
7. Publication and review
This policy and the contact details for both channels are published on SESAMm's website, in accordance with Article 19. The policy is reviewed at least annually and on any material change, and is approved by the Supervisory Board.
