Nidec's credit rating was downgraded to noninvestment grade by Moody's Ratings due to uncertainty about the reliability of the Japanese company's financial disclosures and governance risks.
The U.S. ratings company said Thursday that it lowered Nidec's senior unsecured rating by three notches to Ba3, down from Baa3, the lowest investment grade. Moody's withdrew Nidec's Baa3 issuer rating and assigned a negative outlook.
"The negative outlook captures the risk of further rating pressure depending on the findings of the third-party investigation into potential accounting irregularities," said Roman Schorr, a senior analyst at Moody's.
In September, Kyoto-based Nidec set up a third-party committee to investigate potential accounting irregularities.
Earlier internal probes uncovered documents suggesting that the maker of electric motors and other equipment might have arbitrarily considered the timing of write-downs of risky assets.
