Default risk, three ways
Stock market: distance-to-default
Not computed: financial company (banks, insurers, BDCs and REITs carry leverage as their business, which the model misreads).
Bond market: priced-in odds
A 90 bp spread prices in about 1.5% a year of default odds (spread ÷ (1 − 40% recovery)). Fund-reported marks as of Jul 2026; the spread also pays for liquidity and risk premium, so this overstates actual defaults.
Accounts: Altman Z
Not available.
The stock side: 13F filings
What institutions report holding in AON's stock and options. Options are reported at the value of the underlying shares, not the premium paid; 13F lists long positions only, lags 45 days after quarter-end, and does not show whether puts hedge a stock position.
