Nissan Motor Co. Chief Executive Officer Hiroto Saikawa is due to be questioned by the board on Monday about allegations by a former senior executive that he broke company rules to pay for a house in Tokyo, according to people familiar with the matter.

Saikawa will be asked at the extraordinary meeting whether date restrictions on selling compensation-linked stock were altered in 2013, earning him a higher profit and facilitating payments for the property, said the people, who asked not to be named because the details aren't public. The executive will also be questioned about whether he asked the carmaker to buy the house, and be repaid later in installments, they said.

The possible misconduct was alleged by Greg Kelly in an interview published earlier in June in monthly magazine Bungei Shunju. Kelly was arrested on the same day in November as former Nissan Chairman Carlos Ghosn. Saikawa has denied using company funds to buy his house, saying he bought it with his own money. He has also so far refused to discuss the transaction with the Nissan board, the people said.
