Mutual funds (MFs) must get 90% of their income from stocks, bonds and traditional securities. To bypass this, MFs that invest in derivatives and commodities set up shell corps in the Caymans to do it. They then sell shares in the offshore subsidiary shells to the mutual funds. This way the funds technically invest in SEC allowed instruments, profits go to mutual fund investors free of corp. tax and the investments escape CFTC scrutiny. Scared?
