In the classic Douglas Adams novel 'The Hitchhikers Guide to the Galaxy' the answer to the "great Question of Life, the Universe and everything" was calculated as 42.
However, there's a major fault in this method because the bulk of the $20.5 million labeled as "other scheme expenses" is in fact tax, which even in a fictional world would be attributed to the evil empire.
If you assume that all of the 'other expenses' is tax, then the fairer measure of the default providers costs versus returns is 21 per cent - only half as good a story.
(Using the same process, the non-default schemes cost about 17 per cent of returns - or 28 per cent including the tax-heavy 'other expenses' item.)
