DoCoMo to record impairments

NTT DoCoMo Inc, Japan’s largest wireless carrier, said on Wednesday it would post a 573 billion yen (USD 4.68 billion) appraisal loss on its stakes in foreign carriers but vowed to stand by its partners. Analysts worry that the costly overseas strategy, aimed at promoting DoCoMo’s third-generation wireless technology as the next global standard, may continue to sap its coffers just as it confronts an increasingly competitive home market.
