In Australia, retailers like to do businiess in shopping centers as australians are inclined to shop at shopping centers. even though property price are dropping, it's a tangible asset. It can sell at higher price when propery market recovers. For a business like Allco, it's quite intangible, it's only worth the money it can generate. In economic downturn/recession, airline business is dwindling and so as shipping and the asset value can be written down due as they wears and tears.
