Coal India is another example. The company, after investing close to Rs.500 crore in Mozambique, said it found no coal worth extracting from its two blocks. Analysts now expect the company to write-off the entire investment. The Mozambique foray also turned out to be a value destroyer for Tata Steel and ICVL, a joint venture of Coal India, NTPC and NMDC. In July last year, mining major Rio Tinto sold a 65% stake in its Mozambique mines to ICVL, writing-off its $4 billion investment. The Benga coal mine in Mozambique’s Tete province, in which Tata Steel is also a 35% stakeholder, is losing $7.5 million per month. Similarly, Essar group’s $600 million investment in Trinity Coal Corp in the US turned bad as the company filed for Chapter 11 in 2013. “Several write-downs are seen in situations where companies have made costly acquisitions in the past, and those valuations are not sustainable any longer, resulting in goodwill and asset impairments,” says Venkateshwaran.
