Write a LinkedIn ad

I work in marketing at a financial advice firm. Help me write a LinkedIn ad for a guide, event or service.

Context: This suits business owners, directors and senior professionals: pensions, exit planning, shareholder protection. The reader is short of time and wary of anything that looks like a sales approach.

Before you start, ask me for anything missing from this list:
- What we are promoting
- The job titles we want to reach
- The one action we want

Then:
1. Write three versions with different openings.
2. Say who it is for in the first line.
3. Keep the intro under 150 characters.

Give me:
- Three ad versions with headline and intro text
- Which to test first and why

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:
- Approval of the ad, and of any guide it offers, as a promotion
- Claims about tax savings or returns for people like the reader
- Targeting that implies knowledge of a person's wealth or circumstances
