Schedule of Derivative Instruments in Statement of Financial Position, Fair Value | Primary Risks Managed by Derivatives The table below provides a summary of the gross notional amount and fair value of derivatives contracts by the primary underlying risks, excluding embedded derivatives and associated reinsurance recoverables.
