Olympus Corp. said Friday it was postponing the release of second-quarter earnings pending the results of a probe into $1.4 billion in writedowns and fees related to the company's acquisitions.

The company had been due to announce results next Tuesday, but now aims to do so by the end of the month, spokesman Tsuyoshi Kitada said.

Olympus on Tuesday asked a six-person independent committee — that includes two former judges and a retired prosecutor — to probe allegations by former President Michael C. Woodford after he was axed Oct. 14.
