New Zealand meat company PPCS has extended its takeover offer for rival Richmond for the eighth time. Richmond's stock rose last week to NZ$3.17 (US$1.84), which is 6 cents above PPCS' offer price. The offer was due to close last week but has been extended to 23 May. Under the Takeovers Code, the last possible date that the offer can close is 19 June, which means the offer could be extended beyond 23 May, reported the New Zealand Herald.
