DUBLIN, Ireland, Dec. 12, 2012

DUBLIN, Ireland, Dec. 12, 2012 /PRNewswire/ -- XL Group plc ("XL" or the
"Company") (NYSE: XL) today announced its preliminary net loss estimate
related to Storm Sandy of $350 million, pretax and net of reinsurance and
reinstatement premiums. Approximately 60% of the Company's estimated loss
relates to the Reinsurance segment.

Within the Reinsurance segment, the loss estimate is comprised of
approximately 20% for Marine and 80% for Property Reinsurance, including
catastrophe treaty, per risk treaty and facultative exposures. Within the
Insurance segment, the loss estimate is comprised of approximately 15% for
Specialty lines, including Marine, Fine Art and Specie, and 85% for Property.
This loss estimate is in line with the Company's expectations given the
potential size of this event to the insurance industry as commented on by the
Company during its third quarter earnings call on November 5, 2012.

The Company's estimate is based on its review of individual treaties and
policies expected to be impacted, along with available client data. This
preliminary estimate involves the exercise of considerable judgment. Given
that the facts are still developing, as well as the complexities of the nature
of the event, there is considerable uncertainty associated with the loss
estimate of the event and such estimate is accordingly subject to revision as
additional information becomes available. Actual losses may differ materially
from this preliminary estimate.
