As a result, Prudential <2378.HK> said it will not proceed with a $21 billion rights offering in London and Hong Kong designed to raise money to finance the deal.
The U.K. insurer originally offered $35.5 billion for AIA, then lowered it to $30.4 billion amid resistance from shareholders that the company was overspending.
Pru estimated the cost of the failed AIA transaction so far at about 450 million pounds ($659 million), which includes a break-up fee of 152.6 million pounds.
We listened carefully to shareholders over the price and initiated a renegotiation of the terms with AIG. Unfortunately, it has not been possible to reach agreement, Pru Chairman Harvey McGrath said in a statement. We are therefore withdrawing from the transaction.
Pru did not say that the AIG agreement has been formally terminated but said in the statement that it was expected.
