Key Financial Metrics

Material Changes vs. Prior Period

• Profitability Surge: Net income available to common shareholders increased significantly to $851.1 million in 2009 from $265.1 million in 2008. This improvement was driven by a lower level of catastrophic events in 2009 compared to 2008 (which included Hurricanes Gustav and Ike) and strong investment returns.
• Underwriting Performance: The total combined ratio improved to 88.1% in 2009 from 95.0% in 2008. The Insurance segment achieved an underwriting profit of $32.9 million (Combined Ratio 98.1%) compared to a loss of $29.4 million in 2008. The Reinsurance segment generated an underwriting income of $303.2 million (Combined Ratio 73.7%) compared to $173.0 million in 2008.
• Investment Results: The investment portfolio generated a pre-tax total return of 11.28% in 2009, a significant recovery from the (2.84%) return in 2008. Net realized gains were $143.6 million in 2009 versus a loss of $3.9 million in 2008.
• Reserve Development: The company recorded estimated net favorable development on prior year loss reserves of $189.2 million in 2009, compared to $310.2 million in 2008.
• Share Repurchases: ACGL repurchased 6.7 million common shares for an aggregate price of $458.4 million in 2009. The board authorized an additional $1.0 billion for repurchases in November 2009.

Guidance, Outlook, and Risks

• Outlook: Management noted that while rate stabilization occurred in the first half of 2009, the pricing environment remained largely unchanged by the end of the year due to a lack of significant catastrophic activity in the third quarter. The company expects U.S. catastrophe-exposed business to remain a significant proportion of its book, which may increase volatility.
• Catastrophe Exposure: The company seeks to limit its 1-in-250 year return period net probable maximum pre-tax loss from a severe catastrophic event in any geographic zone to approximately 25% of total shareholders' equity. As of January 1, 2010, the modeled peak zone exposure was a hurricane in the Florida Tri-County area with a net probable maximum pre-tax loss of $750 million.
• Key Risks:
  • Catastrophic Events: Exposure to natural and man-made catastrophes (hurricanes, earthquakes, terrorism) remains a primary risk, capable of causing substantial volatility in results.
  • Reserving Uncertainty: As a relatively new company, ACGL relies heavily on expected loss methods and limited historical data, making reserve estimates inherently uncertain.
  • Reinsurance Counterparty Risk: The company relies on reinsurers to meet obligations; failure of reinsurers could materially impact financial condition.
  • Regulatory Changes: Potential changes in U.S. federal regulation, Bermuda law, and EU Solvency II requirements could impact operations and capital requirements.
  • Investment Risk: Exposure to credit spreads, interest rate changes, and liquidity risks in the fixed income portfolio, particularly regarding mortgage-backed securities.

Important Facts for Investor Verification

• Reserve Adequacy: Verify the stability of loss reserves, particularly given the company's reliance on expected loss methods and the significant favorable development recorded in 2009 ($189.2 million).
• Catastrophe Modeling: Review the assumptions and sensitivity of the catastrophe models used to determine the 25% equity exposure threshold, noting the inherent uncertainty in modeling rare events.
• Investment Portfolio Quality: Assess the credit quality of the fixed income portfolio (95% investment grade at year-end) and the exposure to mortgage-backed securities (MBS) and commercial mortgage-backed securities (CMBS), which totaled approximately $2.6 billion combined.
• Reinsurance Recoverables: Confirm the collectability of $1.72 billion in reinsurance recoverables, noting that 90% were due from carriers with an A.M. Best rating of "A-" or better.
• Capital Structure: Monitor the company's ability to maintain capital levels required by rating agencies and regulators, particularly given the $400 million in long-term debt and $325 million in preferred shares.
