TOKYO (Reuters) - Beer manufacturer Sapporo Holdings Ltd needs to be more transparent about its plans to divest some of its substantial real estate holdings, said a board candidate backed by the Japanese company's largest shareholder. Paul Brough, a former independent director at Toshiba (OTC: TOSYY ) and nominee of Singapore-based 3D Investment Partners, said Sapporo has strong brands but has been plagued with poor results and ineffective capital allocation. "We need to build transparency with our shareholders," Brough said in an interview on Friday. "We need to tell them where we are with the real estate disposal process." 3D Investment said on Monday that shareholder proxy advisory firm Glass Lewis has backed Brough as an outside director for Sapporo, seconding an earlier recommendation by ISS, another proxy advisory firm. Sapporo said it opposes Bough's nomination due to a skill overlap with other directors and because his advisory role with 3D Investment makes him "non-independent."
