Private equity firm Apollo, which offered for £3.3 billion for RPC, said the MoU ensured the pension scheme would not be affected by the acquisition. Under the MoU, Apollo agreed to make cash contributions of 5.2 million pounds a year to the scheme for five years and nine months.

Berry Global Group is considering making a rival offer for RPC Group.
