Purpose:The objectives of this study are twofold.: (i) to establish the extent of Board diversity in both its major surface-level (i.e. age, gender, nationality and tenure diversity) and deep-level aspects (i.e. industry-specific, financial, legal and IT expertise) in selected Maltese Large Family Businesses (LFBs), and to establish whether any inherent characteristics of such entities are perceived as influencing the extent of such diversity and (ii) to assess the influences of such diversity aspects on the major Corporate Governance (CG) factors. This also involves ascertaining the extent to which such influences, if existent, are perceived as advantageous or disadvantageous. Design/Methodology/Approach: Semi-structured interviews were carried out with twenty-six interviewees, consisting of eleven directors, three company secretaries, a CEO, four CFOs, an Institute of Directors representative, four advisory partners, an audit manager and an audit director. Findings: LFB Boards are mostly composed of family members, mostly long-tenured and having a lack of diversity of expertise. Moreover, LFB inherent characteristics, particularly strong emotional ties, may reduce the likelihood of a LFB Board being diverse. Furthermore, tenure and age diversity are the diversity aspects most influential on CG, particularly on attaining effective succession planning. In addition, although the eight major diversity aspects do not influence the CG factors pari passu, they generally influence various CG factors advantageously.
