What RSUI Group does

RSUI Group, Inc. is a wholesale specialty insurance underwriter founded in 1988 and headquartered in Atlanta, Georgia. The company writes specialty property, casualty, professional liability, and management liability coverage on a non-admitted basis across all 50 U.S. states, distributing products exclusively through a limited network of appointed wholesale brokers and managing general agents (MGAs). Its five product lines — Binding Authority, Casualty, Management Liability, Professional Liability, and Property — carry risk capacities up to $100 million per property risk, $25 million per umbrella/excess casualty risk, and $10–$20 million for management and professional liability, with limits structured by insured class (non-profit, private, public). Technology infrastructure centers on the BAonline partner portal for MGAs and internally developed underwriting systems; the company cites data-driven underwriting tools, in-house development capabilities under its CIO, and a formalized Actuarial Department under its Chief Actuary.

The business is a wholly-owned subsidiary of Alleghany Corporation, which became a Berkshire Hathaway company in 2022, giving RSUI the balance-sheet strength reflected in its AM Best A++ (Superior) and S&P AA+ ratings with stable outlooks. RSUI generates revenue through insurance premiums underwritten on individually priced, risk-assessed policies billed annually, with quote-based pricing determined per risk. Its 501–1,000-person workforce includes underwriting leadership averaging more than 20 years of specialty insurance experience, and the company maintains active participation in industry bodies such as the Wholesale & Specialty Insurance Association (WSIA). A planned CEO succession — with Phillip McCrorie stepping down at year-end 2026 and Andrew Whittington becoming CEO on January 1, 2027 — reflects an orderly continuity of leadership within an established operating model.
