A.M. Best Affirms Ratings of Marble Reinsurance Corporation
HONG KONG -- November 13, 2013
A.M. Best Asia-Pacific Limited has affirmed the financial strength rating of
A- (Excellent) and the issuer credit rating of “a-” of Marble Reinsurance
Corporation (Marble Re) (Federated State of Micronesia). The outlook of both
ratings is stable.
The ratings reflect Marble Re’s robust risk-adjusted capitalization and
conservative operating strategy. Marble Re’s risk-adjusted capitalization, as
measured by Best’s Capital Adequacy Ratio, has remained strong and is expected
to improve in the mid-term, owing to strong profitability and a capital
injection from the parent company, Marubeni Corporation (Marubeni) (Japan).
Marble Re reported strong profitability with an average 35% return on equity
in the past three years, largely owing to its favorable underwriting results.
The combined ratio remained at an average of 52% during the period with
limited volatility. With enhanced capitalization through its parent’s capital
injection in April 2013, Marble Re began expanding the product portfolio from
fiscal year 2013 by leveraging the strong relationship with Marubeni’s group
companies. Most of the premium from the new portfolio will be ceded to the
third party reinsurers as Marble Re could secure stable income by earning
ceding commissions, which indicates the limited underwriting risk from the new
Partially offsetting rating factors include an implementation risk regarding
Marble Re’s plan to expand its business portfolio and its parent company’s
credit risk profile. The expansion of product lines would create risk in its
implementation given that the business scope has been limited up to marine
cargo risk, despite Marubeni’s long history in operating its captive business.
As a single parent captive of Marubeni, Marble Re has received a wide range of
support regarding capitalization, management team and its risk management
scheme. As such, Marble Re’s business relies on Marubeni’s credit risk profile
While upward movement on Marble Re’s ratings is unlikely, downward pressure
could arise if there is material deterioration in Marble Re’s risk-adjusted
capitalization or significant downward movement in Marubeni’s credit risk
