Which type of organization is a co-operative operating for the benefit of its members only?

Stock companies are owned by shareholders who invest capital and expect returns on their investments. Unlike mutual organizations, stock companies prioritize profits for their shareholders, which may not align with the interests of members or customers. Their primary goal is to maximize shareholder value, often at the expense of member benefits.

Lloyd's Underwriters operate within a unique insurance market structure where individual underwriters provide insurance coverage. While they may serve clients, their focus is on profitability and risk management for the underwriters rather than the exclusive benefit of members. Hence, they do not fit the definition of a mutual organization.

The Workers' Compensation Board provides insurance and benefits to workers who suffer job-related injuries. While it serves a specific group, it is a regulatory body rather than a mutual organization. Its primary purpose is to administer claims and ensure compliance with labor laws, which does not align with a member-owned structure.
