Thin capitalisation
A company that doesn’t have much in the way of shareholders’ equity, which means if it enters into significant financial contracts, it is liable to blow up, unless it carefully documents them.
A special purpose vehicle is just such a company which uses the technique of applying limited recourse to all of its contractual obligations so that it is bankruptcy remote. Its capital can be as low as $1000. Asset managers also tend to be (comparatively) thinly capitalised (but nothing like as thinly as SPVs do, as they generally act for the account of the funds that they manage, and aren't subject to any regulatory requirements to hold capital. Banks, by contrast, are fatly capitalised. Well, they would be, if there were such a term in common usage.
