The eligibility of the two cornerstone shareholders in RHG to vote at what could prove to be two extraordinary general meetings of the mortgage financier is under the spotlight.On Friday, RHG advised, via the ASX, that John Kinghorn and Geoffrey Kinghorn have resolved to abstain from voting at the EGM called in connection with the planned share buyback and special dividend of a combined 88 cents per share. The Kinghorns, have, however, said their stance may change if there is any change in circumstances.The Kinghorns own around 23 per cent of RHG between them. John Kinghorn, the executive chair, has already said he will not participate in the buyback. His son, Geoffrey Kinghorn, has said he may sell only a minority of his shares in the buyback.Late last week, Wilson Asset Management and Cadence Asset Management foreshadowed plans for a proposal to remove two directors from the board to force consultation over the plan.The two fund managers released a letter to RHG yesterday, again via the ASX, advising on their plans to call a special meeting to remove two directors - Greg Jones and John McGuigan - from the RHG board and to elect three new directors.One object of the shareholder activism is head off the planned delisting of RHG, which is likely to be majority-owned by the Kinghorns following the buyback.If there is a second extraordinary general meeting, as the activist shareholders intend, one view is that the Kinghorns must also abstain on that vote. The Sydney Morning Herald, meanwhile, reports that active bids are on foot for the back book of RHG, suggesting that the market's assessment of the value in this book has moved on since new year, and the sales process described by John Kinghorn last month in the notice of meeting as unable to attract a bid "at any price". The SMH reports that private equity bids and bids from major banks are under discussion.
