Société Générale Securities Services (SGSS) has completed the migration of all BT pension scheme management's over the counter (OTC) business onto the bank's platform.

The BT pension fund is the largest pension fund in the UK with assets of around £35 billion.

SGSS provides the fund with middle office, collateral management, pricing and fund administration for OTC trades.

This migration follows the mandate given to SGSS in 2009 for the de-risking of the BT pension fund and the operational processing of its OTC platform.
