Draft a holding statement

I work in marketing at a law firm. Help me draft a short public statement about a problem.

Context: When something goes wrong, client confidentiality and any report to the regulator or insurer come before public comment.

Before you start, ask me for anything missing from this list:
- What happened, as far as we know
- What we are doing about it
- Who has approved speaking publicly

Then:
1. State what we know and what we do not yet know.
2. Say what we are doing and when we will say more.
3. Avoid blame, guesses and promises.

Give me:
- A statement under 120 words
- Three likely questions with answers
- What not to say

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Give general legal information only. Never write anything that reads as advice on a person's own situation, and never suggest an outcome is likely or guaranteed.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else our compliance officer or the partner who approves marketing should see:
- Sign-off by the managing partner and the compliance officer
- That insurers have been told where the policy requires it
- Nothing that identifies a client or admits liability
