TEXT-Fitch affirms FM Global's 'AA' IFS ratings

Feb 13 - Fitch Ratings has affirmed the 'AA' Insurer Financial
Strength (IFS) ratings of Factory Mutual Insurance Company (Factory Mutual) and
its affiliates (collectively FM Global). The Rating Outlook is Stable.

The ratings continue to reflect FM Global's strong capital and long-term
underwriting profitability, competitive advantages derived from the company's
engineering expertise and global presence in specialty commercial property
insurance markets, as well as benefits drawn from the company's mutual company
status. Partially offsetting these positives is the effect of year-to-year
capital volatility derived from the company's underwriting activities and
long-held common equity investment allocation.

FM Global's 2011 results were severely impacted by record catastrophe losses,
internationally and domestically, generating a well-above average combined ratio
of 121.0%, with significant losses incurred from the Japan and New Zealand
earthquakes, Thailand flooding, as well as Hurricane Irene and numerous inland
storm events in the U.S.

Despite the losses incurred in 2011, the company's long-term operating
performance continues to be strong and supportive of the current rating level.
FM Global's cumulative three- and five-year calendar-year combined ratios on a
GAAP basis through 2011 were 91.1% and 89.3%, respectively.

Fitch believes that FM Global's favorable long-term underwriting performance is
due in large part to the company's ability to incorporate its engineering
expertise into its risk selection and underwriting processes. Fitch views the
company's engineering capabilities and loss prevention services as key
advantages that are difficult for competitors to replicate and believes this
expertise will result in underwriting results that are consistently better than
peers.

FM Global's capital position is very strong. While underwriting losses and
modest unrealized investment losses promoted a 5.5% decline in policyholders'
surplus to $6.9 billion at year-end 2011, the company continues to utilize
operating leverage that is within targets for the current rating. As of
September 30, 2011, annualized U.S. statutory operating and net leverage for FM
Global were 0.49x and 1.37x, which Fitch considers to be conservative and
supportive of the current rating level.

FM Global has no outstanding debt, which Fitch regards as a positive credit
factor relative to other 'AA' rated companies.

Fitch considers an upgrade of FM Global's ratings unlikely, however, key rating
triggers that could, in time, lead to positive pressure include:

--Consistent levels of strong capital associated with higher rating levels over
a multi-year period.
--A material decline in common equity investments, reducing volatility in
surplus.

Key rating triggers for FM Global's ratings that could lead to a downgrade
include:

--Severe deterioration in long-term results, to the point where the historical
10.0 point margin in combined ratio outperformance relative to peers no longer
existed.
--Consolidated U.S. operating and net leverage approaching 0.75x and 1.75x,
respectively.
--A sustained period of net losses or catastrophe losses out of proportion with
market share.

Fitch's ratings on Factory Mutual's subsidiaries, Affiliated FM Insurance
Company (Affiliated FM), Appalachian Insurance Company (Appalachian), the U.K.
domiciled FM Insurance Company Limited (FM Insurance) and the Mexico domiciled
FM Global de Mexico, S.A. de C.V. (FM Global Mexico) reflect explicit and
implicit financial support from Factory Mutual.

--IFS at 'AA'.

Appalachian Insurance Company
--IFS at 'AA'.

Affiliated FM Insurance Company
--IFS at 'AA'.

FM Insurance Company Limited
--IFS at 'AA'.
