Which of the following is NOT a board committee expected to be established at all companies?

The question seeks to identify which board committee is not universally required to be established at all companies.

The correct answer here is the risk committee. While many organizations, especially larger public companies or those in heavily regulated industries, may choose to establish a risk committee as part of their governance practices, it is not a mandatory requirement across all types of companies.

On the other hand, the audit committee is generally considered essential as it oversees financial reporting and compliance with regulations. The nominations committee is typically responsible for identifying and recommending board candidates, while the remuneration committee focuses on executive compensation policies. Both of these committees are commonly established to ensure proper governance, accountability, and oversight within companies. Hence, while they are often seen in many organizations, the risk committee does not have the same level of universal establishment as the other committees listed.
