  A.M. Best Affirms Ratings of The Chubb Corporation and Its Subsidiaries

Business Wire

OLDWICK, N.J. -- March 8, 2013

A.M. Best Co. has affirmed the financial strength rating (FSR) of A++
(Superior) and issuer credit ratings (ICR) of “aa+” of the property/casualty
subsidiaries of The Chubb Corporation (Chubb Corp) (NYSE: CB) also known as
the Chubb Group of Insurance Companies (Chubb Group). Concurrently, A.M. Best
has affirmed the ICR of “aa-”, all long-term debt and indicative ratings and
the AMB-1+ on the commercial paper of Chubb Corp. In addition, A.M. Best has
affirmed the FSR of A++ (Superior) and ICR of “aa+” of Chubb Atlantic
Indemnity Ltd. (Chubb Atlantic) (Pembroke, Bermuda). The outlook for all
ratings is stable, except for the commercial paper, which does not have an
outlook. All companies are headquartered in Warren, NJ, except where
specified. (See below for a detailed list of the companies and ratings.)

The ratings reflect the Chubb Group’s superior risk-adjusted capitalization,
excellent underwriting and overall operating performance and the sustainable
competitive advantages within its specialty and upscale personal insurance
businesses, which is demonstrated by its consistent outperformance of industry
peers. The ratings also recognize Chubb Group’s comprehensive and proactive
enterprise risk management, disciplined underwriting practices, strong
franchise recognition and access to the capital markets through Chubb Corp.
The group’s positive rating attributes are enhanced by its position as a
leading insurer in the United States and its global presence in specialty

The strength of Chubb Group’s balance sheet is derived from its consistent
generation of underwriting profits, despite the recent impact of catastrophes
and competitive market conditions and a well-diversified book of business,
which has led to excellent risk-adjusted capitalization. Chubb Group’s results
also benefit from an above average total return on invested assets and strong
underwriting and operating cash flows.

These positive rating factors are partially offset by challenging market
conditions and catastrophe and weather-related losses, which have impacted
underwriting performance in each of the last three years. Catastrophe losses
added approximately six, nine and 10 points to the group’s combined ratios for
2010, 2011 and 2012, respectively. Management remains focused on limiting
exposures through actively monitoring these risks and maintaining a prudent
reinsurance program. In addition, the group has historically recognized
adverse development of the loss reserves associated with its asbestos and
environmental liabilities, although overall development of loss reserves has
been favorable in recent accident and calendar years. Given Chubb Group’s
leading market position, specialty niche underwriting focus, prudent balance
sheet liquidity, strong cash flows and excellent risk-adjusted capitalization,
A.M. Best considers it favorably positioned and sufficiently capitalized to
absorb these challenges and those posed by the continued competitive market.

Chubb Atlantic’s ratings recognize its solid risk-adjusted capitalization and
the implicit and explicit support provided by Chubb Corp. This financial
support is evidenced by the capital contributions Chubb Corp. has made in
recent years to support Chubb Atlantic’s operations, as well as the business
of Chubb Atlantic’s subsidiary, Chubb do Brasil Companhia de Seguros.
Furthermore, Chubb Atlantic is the beneficiary of sizable irrevocable letters
of credit issued by banks on behalf of Chubb Corp.

The ratings also acknowledge Chubb Atlantic’s strategic importance within the
Chubb Group, including its quota share reinsurance assumed from affiliates.

These positive rating factors are partially offset by the volatility in Chubb
Atlantic’s underwriting performance in prior years, largely due to adverse
loss reserve development.

Chubb Corp.’s debt-to-tangible capital ratio is maintained at a modest 20% as
of December 31, 2012. Despite the company’s ongoing share repurchase program,
liquid assets at the holding company are expected to be maintained at a level
more than sufficient to cover annual holding company expenses.
