common in the UK and Canada, and is sometimes called the British model. Expert opinion is rather evenly divided over which is the preferable model. There is a growing push by public market investors for companies with an executive chairperson to have a lead independent director to provide some element of an independent perspective. The role of the chairperson in a private equity-backed board differs from the role in non-profit or publicly listed organizations in several ways, including the pay, role and what makes an effective private-equity chairperson. Companies with both an executive chairperson and a CEO include Ford, HSBC, Alphabet Inc., HP, and Apple. Vice-chairperson and deputy chairperson A vice- or deputy chairperson, subordinate to the chairperson, is sometimes chosen to assist and to serve as chairperson in the latter's absence, or when a motion involving the chairperson is being discussed. In the absence of the chairperson and vice-chairperson, groups sometimes elect a chairperson pro tempore to fill the role for a single meeting. In some organizations that have both titles, deputy chairperson ranks higher than vice-chairperson, as there are often multiple vice-chairpersons but only a single deputy chairperson. This type of deputy chairperson title on its own usually has only an advisory role and not an operational one (such as Ted Turner at Time Warner). An unrelated definition of vice- and deputy chairpersons describes an executive who is higher ranking or has more seniority than an executive vice-president (EVP). Sometimes, EVPs report to a vice-chairperson, who in turn reports directly to the chief executive officer (CEO) (so vice-chairpersons in effect constitute an additional layer of management), while other vice-chairpersons have more responsibilities but are otherwise on an equal tier with EVPs. Executives with the title vice-chairperson and deputy chairperson are usually not members of the board of directors.
