@Parko5 I am not a corporate governance expert, so in replying here, I am drawing on my own 30-years' experience in publicly listed companies, including extensive exposure to executive teams, CEOs and boards, both in a strategic advisory capacity but also as a management team member. Those members who have a stronger governance background will no doubt be able to answer your question more properly.
It has always been my observation that DW exhibits many of the behaviours you might expect to see in an "Executive" Chair, CEO and Founder/Owner.
From my own observations of his behaviour in investor presentations, I have identified (years before today, recorded in various straws) that this would likely create tensions between his role and the "CEO" and, arguably, also between the Chair and the CFO. Evidence of this is his disclosures in his preamble discussions of key facts that neither appear in the release, the annual report, nor the scripted presentation, but which seem to be disclosed at his whim. (Very odd behaviour for a Chairman. I have often referred to my analysis of these disclosures as me playing "Inspector Clouseau" or watching the "DW Circus".)
I believe that this is a symptom of a leader who engages with managers across the company on an ad hoc basis, as he sees fit, without any agreed code. Of course, this engagement is carried out with the very best of intentions, and perhaps was appropriate when $PNV was more of a "start-up" company.
However, this is quite different from the way in which a Non-Executive Chairman normally engages with the Executive team. It is my experience that, even though less formal interactions are often arranged in a structured and purposeful way, a Non-Executive Chairman will always engage on operational matters via the CEO and CEO/CFO. Where they engage directly with other managers (such as HR Director, Head of R&D etc,) this will be with the knowledge and support of the CEO, or as part of a formal business processes (e.g., reports to the Audit and Risk Committee).
Sometimes, if there is a new CEO in place who is yet to prove themselves. a Chairman might also engage with other Executive Directors on the Management Team or other Executives, with the aim of gathering indepedent perspectives on the business, leadership and culture - particularly over the first 2-3 years, as the new CEO finds their feet and proves themselves. However, there is usually a degree of structure and transparency around these intereactions, so that they do not undermine the authority of the CEO, as the Executive with ultimate accountability for the operational performance of the company.
To me it is entirely unsurprising that Swami, having come from a megacap, multinational like J&J, will have found the "Board" behaviours at $PNV a culture shock. It is entirely unsurprising to me that things have come to a head. That it should have taken so long to do so can perhaps be explained in that these tensions are likely to spill over when performance pressures occur, as we can all see that they have in recent weeks and months.
That is my diagnosis of the situation, based solely on my observation of the actors involved over several years in investor meetings (results, AGMs etc.) I have no knowledge regarding the company and the actors other than that which we have all been able to observe over recent years.
More of my personal experience has been in very large corporations, usually with market caps >$10bn. It is only since coming to Australia in 2010 that I have had exposure to small and medium cap companies. My observation here is that behavioural norms both in Board and Management Team members often fall significantly short of the standards one comes to expect in more mature and well-governed companies. This observation not only applies to "small caps". After all, $PNV, $WTC, and $MIN are all multi-billion dollar companies. Or, at lease, $PNV was. I will go further to say that I have observed things said in ASX-boardrooms that I would never have believed would be said - but, sadly, those are secrets I will never be able to share here!
So has the Board come down on DW's side? Perhaps. Some of the actions appear to recognise gaps in Board capability and the need for succession. But given the earlier release today that the CEO is the one being asked to resign, I think the outcome for the moment is clear.
Tenure+Ownership+Performance perhaps trumps Governance!
BTW @Parko5 nothing in my recent academic career has helped me writing this post. Only my time as a practitioner!
