SYDNEY (Reuters) - BGH Capital, an Australian private-equity firm run by three star dealmakers, was rebuffed on two billion-dollar deals on Monday, underscoring how companies are trying to squeeze out better offers in a market crammed with cash-rich investors. Earlier in the day, Healthscope Ltd (HSO.AX) said it had picked Brookfield Capital Partners’ sweetened offer that values the hospital operator at up to A$4.5 billion ($3.24 billion) over BGH’s A$4.1 billion bid.
