I hasn't really lost £6.4bn, it is more an accounting device, one which coincidently reduces tax payments. However, trading profit is at £1.4bn, OK that is down from about £6bn 18 months ago, but still not to be laughed at - Tesco is having a tough time, but it is not failing.
What the loss really represents is a revaluation of its property portfolio. Unlike the housing market the property market has lost value and Tesco holds a lot of commercial property. Commercial property prices are down because, as we are so often told, the High Street is dying. The irony is that the High St is dying because the big four supermarkets opened stores offering everything under one roof on any plot of land they could find; and the independent shops shut.
Masters of their own downfall, hoist on their own petard.......
Shame.
