House-builder Berkeley Group jumped after seeing both revenues and profits surge in the 2011/2012 fiscal year and saying it would hit its medium-term profit targets quicker than first thought. ?? Meanwhile, two weeks after confirming speculation that it was interested in German engineering group Elster, buy-out firm Melrose said that it is looking to take over the firm by spending $2.3bn, or £1.5bn, causing shares to slip today. Melrose will finance the acquisition and expenses through a combination of new debt and by way of a £1.2bn fully underwritten rights issue. ?
