Aon draws $65bn of bond demand to fund acquisition
Aon's $13.5 billion bond offering to fund its $17 billion acquisition of USI Insurance Services attracted $65 billion in demand, indicating strong investor interest. The deal includes seven tranches with maturities from 3 to 30 years, and yields tightened on the longest tenor. Fitch Ratings placed Aon's debt on rating watch negative, citing increased credit risk. The acquisition is expected to close by year-end, expanding Aon's midsized corporate client footprint.
