Current Responsibility

Aaron Koch is a principal and consulting actuary with Milliman’s Insurance-Linked Securities (ILS) Group, US P&C Division.

Experience

Aaron develops innovative solutions for the rapidly growing catastrophe risk and alternative capital markets. He works with leaders in these fields—including specialist hedge funds and reinsurers—to provide independent analyses and establish best-practice standards for asset valuation, post-event loss reserving, and operational reviews. In addition, Aaron is a frequent writer and speaker on alternative financing structures for catastrophe risk.

Aaron’s actuarial experience includes consulting for a diverse set of clients throughout the property and casualty insurance industry, with a particular focus on the Bermuda market. He frequently develops models for low-frequency, high-severity risks, e.g., property catastrophe and commercial liability risks such as products liability and medical malpractice.
