Non-executive directors at Naibu Global International, a Chinese sports footwear company listed on the AIM stock exchange for fast-growing companies in London, have lost contact with the company's chairman and chief executive. The directors reported through a stock market announcement on 18 Feb. that their enquiries to these two managers have been left unanswered, so that they could not asses Naibu's performance. They have appointed KPMG to prepare a report on the Chinese group's financial position. Naibu shares were listed in April 2012 at £124 pence but their price collapsed to £11.5 pence before trading was suspended in early January without any explanation. The Financial Times reported that two of the top three shareholders have been steadily selling off their stock in Naibu in the last two years. Representatives for Naibu's non-executive directors said they could offer no further update as yet.
