Revolving Credit Facilities

As of March 31, 2023, Aon had two primary committed credit facilities outstanding: its $1.0 billion multi-currency U.S. credit facility expiring in September 2026 and its $750 million multi-currency U.S. credit facility expiring in October 2024. In aggregate, these two facilities provide approximately $1.8 billion in available credit.

Each of these primary committed credit facilities includes customary representations, warranties, and covenants, including financial covenants that require Aon to maintain specified ratios of adjusted consolidated EBITDA to consolidated interest expense and consolidated debt to adjusted consolidated EBITDA, in each case, tested quarterly. At March 31, 2023, Aon did not have borrowings under either of these primary committed credit facilities, and was in compliance with the financial covenants and all other covenants contained therein during the rolling 12 months ended March 31, 2023.

Commercial Paper

Aon Corporation has established a U.S. commercial paper program (the “U.S. Program”) and Aon Global Holdings plc has established a European multi-currency commercial paper program (the “European Program” and, together with the U.S. Program, the “Commercial Paper Program”). Commercial paper may be issued in aggregate principal amounts of up to $1.0 billion under the U.S. Program and €625 million ($673 million at March 31, 2023 exchange rates) under the European Program, not to exceed the amount of the Company’s committed credit facilities, which was approximately $1.8 billion at March 31, 2023.
