Alleghany's objective is to create stockholder value through the ownership and management of a small group of operating businesses and investments, anchored by a core position in property and casualty insurance. Alleghany is managed by a select company staff which seeks out attractive investment opportunities, delegates responsibilities to competent and motivated managers, defines risk parameters, sets management goals for its operating businesses, ensures that managers are provided with incentives to meet these goals, and monitors their progress.

The operating businesses function in an entrepreneurial climate as quasi-autonomous enterprises.

Conservatism dominates Alleghany's management philosophy. Alleghany's philosophy shuns investment fads and fashions in favor of acquiring relatively few interests in basic financial and industrial enterprises that offer the potential to deliver long-term value to the investor.
