Procter & Gamble (PG - Get Report) shareholders voted against adding Trian's Nelson Peltz to its board of investors. 

Though Trian said the vote, which took place on Tuesday, is too close to call.

"According to our proxy solicitors, today's vote is too close to call and it will take more time to determine the outcome. We await the certified election results by the independent inspector of election. Trian is pleased with the support we have received from shareholders and all of the nation's independent proxy advisory firms. We believe shareholders' voices are being heard at P&G today, thanks to Trian's involvement.
