Notes

On January 13, 2021, Aon Global Limited, a limited company organized under the laws of England and Wales and a wholly owned subsidiary of Aon plc, issued an irrevocable notice of redemption to holders of its 2.80% Senior Notes for the redemption of all $400 million outstanding aggregate principal amount of the notes, which were set to mature in March 2021 and classified as Short-term debt and current portion of long-term debt as of December 31, 2020. The redemption date was on February 16, 2021 and resulted in an insignificant loss due to extinguishment.

On May 29, 2020, Aon Corporation, a Delaware corporation and a wholly owned subsidiary of the Company (“Aon Corporation”), issued an irrevocable notice of redemption to holders of its 5.00% Senior Notes, which were set to mature on September 30, 2020, for the redemption of all $600 million outstanding aggregate principal amount of the notes. The redemption date was on June 30, 2020 and resulted in a loss of $7 million due to extinguishment.

On May 12, 2020, Aon Corporation issued $1 billion of its 2.80% Senior Notes due May 2030. Aon Corporation used a portion of the net proceeds on June 30, 2020 to repay its outstanding 5.00% Senior Notes, which were set to mature on September 30, 2020. The Company intends to use the remainder to repay other borrowings and for general corporate purposes.

Revolving Credit Facilities

As of June 30, 2021, Aon plc has two primary committed credit facilities outstanding: its $900 million multi-currency U.S. credit facility expiring in February 2022 and its $750 million multi-currency U.S. credit facility expiring in October 2023. In aggregate, these two facilities provide $1.65 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 earnings before interest, taxes, depreciation, and amortization (“EBITDA”) to consolidated interest expense and consolidated debt to adjusted consolidated EBITDA, in each case, tested quarterly. At June 30, 2021, 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 June 30, 2021.

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 Programs”). Commercial paper may be issued in aggregate principal amounts of up to $900

million under the U.S. Program and €625 million under the European Program, not to exceed the amount of the Company’s committed credit facilities, which was $1.65 billion at June 30, 2021. The U.S. Program is fully and unconditionally guaranteed by Aon plc, Aon Global Limited, and Aon Global Holdings plc and the European Program is fully and unconditionally guaranteed by Aon plc, Aon Global Limited, and Aon Corporation. There was no commercial paper outstanding as of June 30, 2021 and December 31, 2020.

Approximately $400 million of the Regulatory Termination Fee (as defined in Part I, Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations) was paid on July 27, 2021 using proceeds of commercial paper issued by Aon Corporation under the U.S. Program where the aggregate principal was raised on July 26, 2021.
