Two private equity consortia interested in buying Warner Chilcott, a Northern Ireland-based pharmaceuticals company, have until the end of the week to decide whether to outbid a third consortium, led by Goldman Sachs, which tabled an offer on Monday.

Goldman Sachs is advising its own private equity arm, which is in a consortium with Blackstone, Kohlberg Kravis Roberts and Texas Pacific Group. The consortium has offered 837p a share for Warner Chilcott.
