Investment bank reviwing its options after £9.4bn friendly bid was rejected over the weekend.

Goldman Sachs could increase its £9.4bn friendly bid for BAA after the airports operator rejected the approach over the weekend.

The investment bank had offered 870p per share, an increase on Spanish construction group Ferrovial's two previous offers of 810p a share, which valued BAA at £8.75m.

Goldman Sachs said that its consortium was now reviewing its options over a second attempt to persuade BAA to accept a friendly bid.

A statement from the investment bank said: "Following BAA's rejection of that proposal, the consortium is continuing to review its options. As a result there can be no assurance that any offer will be made, nor as to the terms of any offer if one should result."

BAA rejected Goldman Sachs' 870p approach, saying "it clearly fails to reflect the true value of the company".
