Guinness Peat Group says the fundable pension deficit in the Staveley scheme has been agreed with the fund's trustee at £20 million.
The investment group also says it will make additional contributions of more than £15 million over eight years to clear the deficit.
GPG says the agreement with the trustee does not extend the £130 million already committed to supporting GPG's Staveley and Brunel pension plans.
The company also has pension commitments in Coats and the ultimate size of these liabilities remain uncertain.
