LONDON, March 6 (Reuters) - British insurer Aviva has agreed to transfer the risk of members of its staff pension scheme living longer than expected to three reinsurers for 5 billion pounds ($8.4 billion) in the largest deal of its kind.
Aviva's transaction by itself represents more than half of the total 8.9 billion pounds of longevity swaps in 2013 and is substantially larger than the previous 3.2 billion pound record set by BAE Systems last year.

The swap is the first of 2014 and lifts total issuance since the first deal in 2009 by 20 percent to 30.1 billion pounds.
