In a quick reversal, Aon is abandoning its $US23.5 billion takeover attempt of Willis Towers Watson. Because Willis is an Irish company, Aon was forced to disclose its interest Tuesday due to Irish takeover regulations.

“As a result of media speculation, those regulations required Aon to make the disclosure at a very early stage in the consideration of a potential all-share business combination,” Aon said in a press release out Wednesday. “Aon today confirms that it does not intend to pursue this business combination.”

After calling off the all-share deal Wednesday, stock prices from both companies returned to preannouncement levels. Willis Tower shares were trading down 5% and Aon was up 6%.

Aon and Willis are two of the largest traded insurance brokers, which connect buyers and sellers of insurance. Research analysts indicated that any potential transaction may face regulatory issues given the market share of both companies.
