⚠ Minority Stakes Can Be Written Down Without a VoteModerate threat

Marubeni (8002) — threat to the moat

The stakes that earn most in good years were the ones written down in 2020, and a minority partner cannot act to stop it.

The worst year in Marubeni's recent history was a year of other people's assets. It lost ¥197.5 billion in the year to March 20201, and the after-tax impairments listed in the results read like a map of its partnerships: ¥94.0 billion on oil and gas in the Gulf of Mexico, ¥60.3 billion on the Chilean copper investment, ¥57.5 billion on the UK North Sea, ¥39.2 billion on the aircraft-leasing investment and ¥78.3 billion on Gavilon2.

Five write-downs, most of them on assets Marubeni did not operate, turned the year into a ¥197.5 billion loss.

A minority investor carries the downside of a price collapse fully and controls none of the operating response. It cannot close a shaft, cut a capital budget or sell the asset without its partners. The same stakes that made the associates line larger than operating profit in 2026 are the ones that produced the 2020 loss.

It was not the only such year. The results for the year to March 2016, when profit fell to ¥62.3 billion3, were depressed by impairments in the Chilean copper business, the Australian iron ore business and oil and gas development, which the following year's report described as non-recurring4. The same kinds of asset, written down twice in five years.

The latest year had smaller versions of the same thing: an impairment of about ¥11 billion on property in the exploration and production business and about ¥11 billion on an Indonesian geothermal power project5.

The measure is impairments as a share of equity-method income. A year in which write-downs of associates approach a fifth of the income booked from them would be the 2020 pattern repeating on a smaller scale.
