Business Overview: White Mountains is a Bermuda-based holding company operating through four primary segments: OneBeacon (specialty, personal, and commercial P&C insurance), White Mountains Re (global reinsurance), Esurance (direct-to-consumer personal auto insurance), and Other Operations (investments, weather derivatives, and variable annuity reinsurance).

Key Financial Metrics (Year Ended Dec 31, 2006)

Segment Performance Highlights

• OneBeacon: Pre-tax income of $311.6 million; Combined ratio of 96% (improved from 98% in 2005). Net written premiums decreased 8% to $1,957.6 million due to the sale of the NFU and Agri divisions.
• White Mountains Re: Pre-tax income of $237.0 million (vs. loss of $17.4 million in 2005); Combined ratio of 102% (improved from 118% in 2005). Improvement driven by lower catastrophe losses compared to the 2005 hurricane season.
• Esurance: Pre-tax loss of $8.0 million (improved from $12.5 million loss in 2005); Combined ratio of 108%. Net written premiums grew 71% to $595.9 million.
• Other Operations: Pre-tax income of $189.2 million, driven primarily by the $171 million gain on the OneBeacon IPO.

Material Changes vs. Prior Period

• Catastrophe Losses: 2006 results included $70 million in after-tax losses from adverse development on 2005 hurricanes (Katrina, Rita, Wilma), a significant improvement over the $288 million in after-tax losses recorded in 2005.
• Investment Results: Net realized investment gains increased to $272.7 million in 2006 from $112.6 million in 2005. This was largely due to a $165 million pre-tax loss on Montpelier Re investments in 2005 versus a $5 million gain in 2006.
• OneBeacon Reorganization: The IPO of OneBeacon Ltd. resulted in a $171 million gain and a shift in segment reporting, moving certain businesses from "Other Operations" to the "OneBeacon" segment.
• Debt Structure: Total debt increased to $1.1 billion, primarily due to the drawdown of $320 million on a new $500 million revolving credit facility (WTM Bank Facility) established in November 2006.

Guidance, Outlook, and Risks

Management Commentary: Management attributes the strong 2006 performance to favorable weather conditions, strong investment returns, and the gain on the OneBeacon sale. The Company emphasizes a disciplined underwriting approach and a focus on total return on investments.

Risks and Contingencies:

• Catastrophe Exposure: Significant exposure remains to Northeastern U.S. windstorms, California earthquakes, and U.S. Atlantic/Gulf Coast windstorms. The Company relies on catastrophe modeling and reinsurance to manage these risks.
• Reinsurance Collectibility: The Company remains liable for reinsured risks. Credit risk exists if reinsurers (e.g., Olympus, NICO) fail to pay. The Company has indemnified Olympus for $137 million of hurricane losses.
• Reserve Adequacy: Loss reserves are estimates subject to uncertainty. Adverse development in prior accident years (particularly asbestos and environmental claims) could materially impact future results.
• Legal Proceedings: Ongoing arbitration with Liberty Mutual regarding unallocated loss adjustment expenses (ULAE) totaling approximately $68 million. OneBeacon believes its reserves are sufficient to cover anticipated outcomes.
• Regulatory: Subject to state and international regulation regarding capital adequacy, dividends, and market conduct. The Company is domiciled in Bermuda and holds a tax protection assurance until 2016.

Investor Verification Checklist

• OneBeacon IPO Impact: Verify the sustainability of earnings post-IPO, as the $171 million gain is a non-recurring item.
• Catastrophe Reserve Development: Monitor the $70 million adverse development on 2005 hurricanes to ensure no further significant adjustments are required.
• Reinsurance Recoverables: Assess the collectibility of the $4.0 billion in reinsurance recoverables, particularly the $655 million due from Olympus and the $2.2 billion due from Berkshire subsidiaries (NICO/GRC).
• Asbestos & Environmental (A&E) Exposure: Review the $1.2 billion in A&E reserves (net of third-party reinsurance) and the remaining $404 million capacity under the NICO Cover.
• Debt Covenants: Confirm compliance with the new WTM Bank Facility covenants, including minimum net worth and interest coverage ratios.
• Montpelier Re Investment: Track the performance of the remaining Montpelier Re investment ($67 million) given the significant volatility experienced in 2005.
