TOKYO, Oct 16 (Reuters) - Chip equipment maker Kokusai Electric (6525.T) has raised $724.4 million after pricing its shares at the top end of their marketed range in Japan's largest initial public offering in five years. Kokusai, owned by U.S. private equity firm KKR (KKR.N), set its IPO price at 1,840 yen per share, according to a filing on Monday, valuing the company at 423.9 billion yen ($2.8 billion). If an overallotment option for domestic investors is exercised, the offering would raise roughly $833 million. The move was partly due to a lacklustre share price performance by chip designer Arm since its listing last month, a source familiar with the matter has said. Kokusai's largest customers are Samsung Electronics (005930.KS), TSMC (2330.TW) and Micron Technology (MU.O), collectively accounting for more than 40% of its revenue.
