What kind of board structure is promoted by the Sarbanes-Oxley Act?

The Sarbanes-Oxley Act, enacted in 2002, primarily aims to enhance corporate governance and accountability among publicly traded companies. A significant aspect of this legislation is the requirement for boards of directors, particularly audit committees, to be composed of independent members. This independence from company insiders is intended to prevent conflicts of interest and ensure that the board can act in the best interest of shareholders without undue influence from management.

By promoting a board structure that emphasizes reliance on independent members who do not have material relationships with the company, Sarbanes-Oxley helps to foster greater oversight of financial reporting, internal controls, and overall corporate governance. This is crucial in restoring investor confidence in the wake of financial scandals that prompted the Act's creation.

The other options suggest varying degrees of insider influence, which would not align with the Sarbanes-Oxley Act's goal of strengthening the integrity and independence of corporate governance structures.
