Regulated investment companies (RICs) are the traditional mutual funds through which many individuals invest. Like a PTP, at least 90% of a gross income must be qualifying income. Qualifying income for a RIC includes dividends; interest; payments with respect to securities loans; and gains from the sale or other disposition or stock or securities or foreign currencies, or other income (including but not limited to gains from options, futures, or forward contracts) derived from its business of investing in the stock, securities, or foreign currencies. I.R.C.§851(b)(2)(A).
Note: I.R.C. §851(b)(2)(B) adds, net income derived from an interest in a publicly traded partnership to the list; however, only the items listed in §851(b)(2)(A) are qualifying income for a PTP.
