The disclosure gap that opens the day a passporting notification is filed
By Lee Konstanty, Product and Partnerships at arbitr
A MiFID II authorized firm, or a Solvency II authorized firm passporting under freedom to provide services, can be legally authorized to operate in a new EU or EEA host state within about a month. Branch establishment under Solvency II runs longer. Producing a compliant, host-language disclosure suite, including a Key Information Document (KID), on that same timeline is a different problem entirely regardless of route. The gap between the two is not a paperwork delay. It is a content production problem, and it starts on the day the notification takes effect.
The notification moves faster than the content stack
Under MiFID II Article 34, an investment firm authorized in one EU member state that wants to provide services in another submits a passporting notification to its home national competent authority (NCA). The home NCA forwards the file to the host NCA within one month of receiving complete information. The firm may begin providing services in the host state on receipt of that communication, or, at the latest, one month after the home NCA sent it. Solvency II sets out two separate routes with different timelines. An insurer providing services across a border under freedom to provide services (Articles 147 to 149) faces a broadly comparable one-month home-authority notification window. An insurer establishing a branch (Articles 145 and 146) faces a longer, two-stage process: the home authority has up to three months to communicate the file to the host authority or state its reasons for refusing, and the host authority then has up to two months to set any general-good conditions before the branch may start business.
Both regimes were built to make cross-border expansion administratively light. Neither regime pauses for a firm's content operations to catch up. The moment the host state clock starts, the firm is expected to have host-language disclosure documents and a compliant KID ready in the host state's official language, not whenever the localization backlog clears.
What the gap actually contains
The content obligation that opens on notification is specific, not general. A firm now operating in a new host state under MiFID II typically needs, in that state's language:
- A Key Information Document that meets PRIIPs formatting and disclosure requirements for the host market
- Client-facing disclosure documents (costs and charges, conflicts of interest, best execution policy) that reference the correct host-state regulatory bodies, not the home NCA
- Terms of business and onboarding documentation a host-state client can rely on
- Regulatory correspondence and filings addressed to the host-state supervisory authority
For a Solvency II undertaking, the equivalent list includes host-language policy wording, pre-contractual information documents, and claims-handling disclosures that meet the host state's implementing rules, not the home state's.
None of this is marketing copy. Every document in that list carries a specific regulatory citation, a specific national authority, and a specific liability if it is wrong. That is what makes the gap expensive to leave open, and what makes it hard to close with a translation process that treats a KID the same way it treats a product brochure.
Why the gap opens even for firms that already translate content
Firms that already translate marketing or product content for other markets often assume the same process covers passporting. It usually does not, for two structural reasons.
First, the content is regulated, not promotional. A KID or a disclosure document has a required structure and required terminology set by the regulation itself. Translating it without domain-specific terminology review can produce a document that reads fluently but does not satisfy the host regulator's actual requirement.
Second, the timeline is set externally. A firm chooses when to run a marketing campaign. It does not choose when its passporting notification takes effect. The one-month notification window is set by the regulator, and the content obligation starts on that date whether or not the firm's localization pipeline was built with that date in mind.
The result: a firm that is legally authorized to operate in a new host state, and structurally unable to produce compliant disclosure content in that state's language on the same clock.
Closing the gap without standing up a new localization function
arbitr translates disclosure, KID, and compliance content through its banking specialist and insurance specialist, vertical-specific agents that carry the terminology conventions for cross-border financial and insurance disclosure content. Every translated segment carries a Confidence Score, and segments that fall below threshold are flagged for reviewer approval rather than shipped unreviewed. Once a reviewer confirms a segment, that decision writes back to the firm's Cortex from day one and is reused in future translation work, so the same disclosure terminology call does not have to be re-approved from scratch in the next filing.
This does not replace legal or compliance review of the final document. It removes the excuse that a compliant host-language disclosure stack has to wait for a dedicated localization function to be hired and staffed before it can exist. Translation today, content operations tomorrow.
Frequently asked questions
What is passporting under MiFID II or Solvency II? Passporting is the notification procedure that lets a firm authorized in one EU or EEA member state provide services or establish a branch in another member state without a separate authorization. MiFID II Article 34 governs investment firms; Solvency II Articles 145 to 149 govern insurance and reinsurance undertakings.
How long does a passporting notification take to become effective? Under MiFID II Article 34, the home competent authority forwards the notification to the host competent authority within one month of receiving complete information, and the firm may begin providing services on receipt of that communication or, at the latest, one month after the home authority sent it. Solvency II timelines depend on the route. Freedom to provide services (Articles 147 to 149) follows a broadly comparable one-month home-authority window. Branch establishment (Articles 145 and 146) is a longer, two-stage process: the home authority has up to three months to communicate the file to the host authority or state its reasons for refusal, and the host authority then has up to two months to set general-good conditions before the branch may start business.
What host-language content does a firm need once passporting takes effect? At minimum: a Key Information Document that meets PRIIPs requirements for the host market, client-facing disclosure documents that reference host-state regulatory bodies, terms of business, and, for insurance undertakings, policy wording and pre-contractual information documents that meet the host state's implementing rules.
Why is a general translation process not sufficient for this content? Disclosure and KID content has a required structure and terminology set by regulation. A process without financial or insurance-specific terminology review can produce a document that reads fluently but does not meet the host regulator's substantive requirement.
Does arbitr perform the compliance review itself? No. arbitr translates the content through vertical specialist agents, with a Confidence Score on every segment and reviewer approval on anything below threshold. That review happens inside one system, so the firm is not standing up a second review tool alongside its existing process. Once a human confirms a segment, that decision writes back to the firm's Cortex and is reused in future translation work, rather than the same terminology call being re-decided from scratch in the firm's next passporting filing. Legal and compliance review of the final content remains the firm's own function.
