Bilingual lockstep means the Thai and English versions of the sustainability disclosure are drafted in parallel from the same indicator framework — not produced sequentially with translation downstream. The conventional Bangkok model is consulting firm drafts in one language, translation vendor produces the second language under tight deadline at lower margin. This introduces drift: technical terms like “double materiality,” “scenario analysis,” “physical risk,” “transition plan” land differently across languages.

FTSE Russell scores public disclosure as written — including the Thai version. Drift between languages costs scoring points. Lockstep prevents this: both versions stay calibrated to the same indicator because both are written from the same indicator.

A translated report is a derivative artefact. The translator typically does not have access to the underlying FTSE indicator framework, GRI 2021 disclosure conventions, IFRS S2 §22 scenario requirements, or SASB sector-specific KPIs. The translator’s brief is fidelity to the source — not indicator calibration in the target language.

A lockstep report is a primary artefact in both languages. The bilingual senior editor controls terminology decisions in real time. The CAT/TM bilingual termbase is maintained against FTSE, GRI 2021, IFRS S2, and SASB conventions specifically. Specialist credential-holders (AA1000AS, GRI 2021 Trainer, IFRS S1/S2) are embedded in drafting decisions — not just post-draft QA.

A standard v10 bilingual sustainability report aligns simultaneously to five frameworks: GRI Standards 2021 (Universal + applicable Sector Standards), SASB Industry Standards (sector-specific KPIs, financial materiality lens), IFRS S1 (general sustainability-related disclosure, Thai SEC mandatory from 2026), IFRS S2 (climate-related disclosure, §22 scenario analysis, TCFD subsumed), and FTSE Russell methodology (14 themes, 300+ indicators, ICB-weighted).

Additional alignments available where relevant: CDP (Climate / Water / Forests), MSCI ESG Ratings key issue framework, S&P CSA / DJSI questionnaire, Sustainalytics ESG Risk Rating, Thailand Taxonomy, ICMA Green Bond / Sustainability-Linked Bond Principles for sustainable finance issuers.

Page counts vary by company size, sector, and disclosure scope. Typical ranges for the primary deliverables: Standalone sustainability report — 60 to 180 pages each language (most SET-listed reports land in the 90–140 page range each language); 56-1 One Report ESG section — 15 to 40 pages each language integrated with the broader annual report; IFRS S2 climate section — 25 to 60 pages each language (as a standalone module or integrated).

Page count is not the primary cost driver — disclosure complexity, framework breadth, design integration scope, and TM leverage from prior years are. Quote within one business hour of source files and NDA.

The standard seven-month cycle runs October through April: October diagnosis and FTSE gap analysis; November materiality and KPI inventory; December calibration and termbase lock; January–February parallel bilingual drafting; March Wk 1–2 designed-proof reading pass; March Wk 3–4 56-1 SEC filing by 31 March deadline; April–May publication and rating agency submissions.

Compressed timelines accommodate late-onboarding clients (4-month minimum with reduced gap-analysis scope). Extended timelines accommodate complex multi-entity groups or first-time reporters. Engagement is best initiated 6–8 months before the 31 March filing deadline.

Two-component structure: Component 1 — Advisory Layer (fixed): FTSE gap analysis, cross-framework mapping, materiality, KPI inventory, climate scenario approach, rating agency strategy. Priced as fixed engagement on Engage / Standard / Pioneer tiers based on company size and sector complexity.

Component 2 — Production Layer (per-word, 5 TM tiers): Tier 1 no match (100%), Tier 2 fuzzy match 75–99% (~50%), Tier 3 100% TM match (~25%), Tier 4 repetition (~10%), Tier 5 designed-proof reading (fixed). Year-two and beyond TM leverage delivers 30–40% effective unit cost reduction. Multi-year retainer letters available. Quote within one business hour of source files and signed NDA.

Othello’s in-house bench includes an ACSAP-certified AA1000AS Sustainability Assurance Practitioner (AccountAbility, June 2024) and an ISO 14064 Lead Auditor (CQI/IRCA). The bench has prior Assurance Project Manager track record across major SET-listed corporates including environmental indicator assurance, AA1000AS Type 1 and Type 2 engagements, and community KPI assurance.

For independence reasons, where Othello has drafted the bilingual sustainability disclosure, third-party AA1000AS assurance is conducted by an external assurer (we coordinate the process). Where Othello is engaged for assurance services on a report drafted elsewhere, the AA1000AS assurance can be performed by the in-house bench. Conflict-of-interest checks are run before engagement.

First-time reporters require a more extensive initial gap analysis and materiality assessment phase. The seven-month standard cycle is extended to 9–10 months for first-time reporters, with an additional 6–8 week scoping phase covering: stakeholder mapping, double materiality assessment (GRI 3 / ESRS-aligned), KPI baseline data collection, internal governance structure for sustainability oversight, and selection of applicable frameworks based on sector and investor base.

Year-one engagements price higher than year-two because the translation memory is built from scratch and the cross-framework mapping is fresh. Year-two unit costs typically drop 30–40% via TM leverage. First-time reporters are a common Othello engagement — particularly for newly-listed SET companies and SET-listed subsidiaries graduating to standalone disclosure.

Yes. The disclosure inventory built for the bilingual sustainability report becomes the source material for all major rating agency and disclosure programme submissions. CDP (Climate Change, Water Security, Forests — A–F scoring), MSCI ESG Ratings (AAA–CCC, industry-key-issue exposure), S&P CSA / DJSI (annual questionnaire ~80–120 questions), Sustainalytics (Morningstar ESG Risk Rating 0–100 scale).

Each agency’s submission uses the underlying disclosure as source but maps it to that agency’s specific question set and language conventions. Post-publication Q&A and follow-up engagement with rating analysts is supported through the reporting cycle.
