Where do Aon plc's ratios come from?
Every ratio is computed from Aon plc's SEC filings — trailing-twelve-month flows over period-end balances. Valuation multiples combine those fundamentals with market data, recomputed each period. Switch between quarterly, annual, and TTM, or open any ratio for its full history and peer comparisons.
