Under the Investment Company Act of 1940, investment companies pool capital into three structures: Face-Amount Certificate companies, Unit Investment Trusts (UITs), and Management Companies (Open-end and Closed-end).
Open-end mutual funds calculate NAV at the close of trading (4:00 PM ET) using forward pricing. Class A shares feature front-end sales charges with breakpoints and Letters of Intent (LOI). Class B shares carry contingent deferred sales charges (CDSCs), while Class C shares levy ongoing level 12b-1 fees.
Exchange-Traded Funds (ETFs) track benchmarks with intraday liquidity and pass-through tax efficiency via creation/redemption units. Real Estate Investment Trusts (REITs) avoid corporate taxation if they distribute at least 90% of their net taxable income to shareholders, but distributions are taxed as ordinary income.
