Arch Delivers Superior Results with Lower Volatility

Arch's playbook is built on the DNA of a specialty insurance powerhouse. Our operating principles are:

FOCUS ON SPECIALTY

INSURANCE BUSINESS

  • We focus on commercial lines where our underwriting expertise enhances risk selection and returns.
  • Examples of specialty lines include:
    • Insurance: Professional and Excess and Surplus (E&S) are more difficult and require deeper expertise to generate adequate, through-the-cycle returns.
    • Reinsurance: Sophisticated modeling and portfolio construction can mitigate volatile property catastrophe returns.
    • Mortgage: Innovative pricing and risk models drive performance.

MANAGE

THE CYCLE

  • Our executive and underwriting teams are compensated on long-term profitability, not just generating new premium.
  • We allocate capital to the lines of business with the best relative opportunity for risk-adjusted returns.
  • Simple in concept, difficult to execute. Successful insurers write more business when opportunities are good and less when conditions deteriorate.

EFFECTIVELY

ALLOCATE CAPITAL

  • When excess capital exists, we deploy according to the below priorities:
    1. Reinvest into our business.
    2. Reduce financial leverage.
    3. Return excess capital to shareholders via buybacks and dividends.
