What is AON's fair price?

Two classic value formulas, with today's numbers. The current price is US$275.95.

Graham's fair price
US$137.06
50.33% below the price

√(22.50 × US$18.45 × US$45.25)

Benjamin Graham paid no more than a P/E of 15 and a P/B of 1.5. Their product, 22.5, times earnings (EPS) and book value per share gives the fair price.

Bazin's ceiling price
US$40.45
85.34% below the price

US$2.43 (5-year average) ÷ 6%

Décio Bazin only bought shares yielding at least 6% a year in distributions. The ceiling price is the average dividend per share of recent years divided by 6%.

Graham ignores growth and debt; Bazin assumes past distributions will repeat. They are reference points for comparison, not a buy recommendation.
