The firm took its present shape through Patrick Ryan's 1982 combination of Ryan Insurance with Combined International, and it now brokers insurance and reinsurance and advises employers on benefits and pensions. Brokers earn commissions and fees without carrying underwriting risk, so results track commercial insurance pricing and client payrolls rather than claims experience. A move of legal domicile to Ireland in 2020 followed an earlier shift to London. Talent is the balance sheet in a business where client relationships travel with individual brokers. The company is incorporated in Ireland, with operations run from London.

A protective put caps your downside on the AON position at a chosen floor; a zero-cost collar pays for that floor by capping the upside. This calculator prices both structures off the current AON option chain, with annual cost, max loss, and tax-treatment notes.
Example: a 5,000-share AON position at $343.2 is worth $1,716,000. A 1-year 30%-OTM put on that position typically runs 2-4% of position value per year (about $34,320 to $68,640) before any premium offset from a short call. The calculator prices both structures off AON's current option chain so you see the actual cost for your chosen floor, tenor, and cap.

Aon equity questions
- How much does it cost to hedge AON stock?

A zero-cost collar lowers that cost by selling away some upside. The calculator above prices both structures off the current AON option chain and shows the annual cost, maximum loss, and tax treatment.
- Does Aon grant ISOs, NSOs, or RSUs?
- Equity compensation at Aon typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
