Which of the following must a Risk Retention Group share?

The correct answer relates to the concept of Risk Retention Groups (RRGs), which are specialized entities designed to provide liability insurance to their members. The defining characteristic of a Risk Retention Group is that it shares common business endeavors among its members. This means that the members of an RRG typically have similar risks and can benefit from pooling their resources and risks in order to provide insurance coverage that might be difficult to obtain independently.

Risk Retention Groups enable businesses with similar risk profiles to work together, allowing them to manage exposure more effectively and provide competitive insurance offerings while sharing the associated risks and costs. This collaborative approach is fundamental to how RRGs operate and allows for a unique structure that supports members' needs.

The other choices do not accurately describe the fundamental aspect of Risk Retention Groups. Ownership among shareholders isn’t applicable as RRGs can be structured as mutual organizations without traditional shareholder models. Insurance policies from other states and licenses for international operations are not required characteristics of RRGs but rather deal with regulatory aspects of insurance that differ from their core purpose of shared risk and collaborative insurance provisioning.
