Who is permitted to hold shares of voting stock or policyholder proxies of a domestic insurer?

The rationale behind the correct answer is that any person can hold shares of voting stock or policyholder proxies of a domestic insurer specifically for the purpose of controlling the management of the insurer. This could include acting as a voting trustee or in a similar capacity, which emphasizes the importance of governance and management control in the insurance industry.

Permitting individuals to hold such shares provides flexibility in managing the insurer's operations while ensuring that those with significant interest have a say in management decisions. This aligns with regulatory practices that focus on maintaining effective governance structures within the insurance sector.

In contrast, the other options impose unnecessary restrictions that do not align with the established legal framework. For instance, limiting shareholding to government officials or licensed insurance agents restricts the pool of qualified individuals who can participate in the management of the insurer. Similarly, requiring shareholders to make a minimum investment could hinder broader participation and deter potential investors who may contribute to the insurer's management and oversight capabilities. Thus, allowing any person who meets the necessary qualifications to hold shares fosters a broader and potentially more effective management structure within domestic insurers.
