Home Capital Group is standing behind Warren Buffett's Berkshire Hathaway bid to increase its stake in the company after leading proxy advisory firm Institutional Shareholder Services advised investors to vote against the deal. The Toronto-based alternative lender said Wednesday its prospects have improved since the American billionaire's conglomerate announced in June that it would support Home Capital through an initial investment of $153 million for a 19.99 per cent stake in the company and by providing it with a $2 billion line of credit. That investment required only regulatory approval, which it received at the end of June. Berkshire also agreed to invest a further $246.7 million, at $10.30 per share, which would increase its indirect stake in Home Capital to 38.4 per cent. This round requires shareholder approval in a vote on Sept. 12.
