Quote from Invoco:
Man,
As an attorney, I am not sure what "legal risk" you are referring with respect to a partnership. There is no greater legal risk to a US investor in a US partnership than in an offshore partnership.
I have worked with hundreds of hedge funds as general counsel to a publicly traded brokerage firm as well as in private practice. Some of the larger US funds had offshore operations but this is not typical.
The goal of a start up hedge fund (with an new manager) is to get off the ground with the best structure available at the least expense. For US hedge funds this is either a limited partnership or LLC structure.
Managment of individual accounts is problematic because all states have limitations on the number of accounts that can be managed without the manager becoming registered as an investment adviser. Further, state and federal laws limit the ability of an investment adviser to receive a portion of the trading profits.
