Draft a holding statement

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

Context: When something goes wrong, such as a data breach, a provider failure or an adviser's sudden departure, clients first want to know whether their money is affected.

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 financial information only. Never write anything that reads as a personal recommendation, and never suggest that a return, a saving or 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 whoever approves our financial promotions should see:
- Sign-off by senior management and the compliance officer
- That the regulator, network and insurers have been told where needed
- Nothing that identifies a client or admits liability
