Kohlberg, Kravis Roberts, the buy-out firm, is poised to price the initial public offering of Alea, the Bermuda-based reinsurer.

The initial public offering could be priced as early as this week, according to equity market sources. Goldman Sachs and Merrill Lynch will manage the deal, which will see Alea list in London. The flotation is expected to raise at least £400m (€575m).
