UPDATE 1-Renesas CFO says financial impact of fire limited in mid-term

(Adds executive comments, background on plant damage)

TOKYO, March 31 (Reuters) - The chief financial officer at Japan’s Renesas Electronics Corp told a shareholders meeting on Wednesday that while a fire at its chipmaking plant would have immense impact on short-term finances, the medium-term impact will be limited.

That financial impact will not affect plans to buy Dialog Semiconductor PLC, Shuhei Shinkai said, without elaborating on the short and mid-term time frames involved.

The Japanese chipmaker on Tuesday said it would take at least 100 days for production to normalise at a factory that suffered a major blaze on March 19. Japan’s government has since urged Taiwanese peers to help with chip production.

The fire at the Naka plant followed soon after an earthquake stopped production for three days last month. In 2011, the plant shut down for three months after an earthquake and tsunami devastated Japan’s northeast coast.

Chief Executive Officer Hidetoshi Shibata said on Wednesday that while the scale of fire damage is less than the earthquake a decade ago, there is a bigger hurdle towards recovery due to chemical pollution caused by the fire.

Renesas’ share price was down 0.8% at the midday trading break in Tokyo, in line with the benchmark Nikkei average . (Reporting by Eimi Yamamitsu; Editing by Jacqueline Wong and Christopher Cushing)
