Authorized Participant

An index ETF and an index mutual fund track the same benchmark and hold nearly identical portfolios. Over many years, however, the ETF distributes materially fewer taxable capital gains to its shareholders. The PRINCIPAL reason is that:

1. A.An ETF's realized gains are exempt from federal taxation under the Investment Company Act.Wrong. No such exemption exists. ETFs and mutual funds are taxed under the same regulated investment company framework.
2. B.The ETF satisfies large redemptions by delivering a basket of portfolio securities IN KIND to an authorized participant, so it does not have to sell appreciated positions.Correct. In-kind redemption avoids realizing gains, which is the structural source of the ETF's tax efficiency.
3. C.ETF shareholders trade only with each other on an exchange, so the fund itself never has any portfolio turnover.Wrong. Secondary trading does explain part of the effect, but the fund still turns its portfolio over to track index changes.
4. D.An ETF may retain realized capital gains indefinitely, while a mutual fund must distribute them.Wrong. Both must distribute realized gains to preserve pass-through treatment. The ETF simply realizes fewer of them.

Why: The difference lies in how each vehicle meets redemptions. A mutual fund facing net redemptions must sell portfolio securities for cash, realizing gains that are then distributed to all remaining shareholders - including those who did nothing. An ETF redeems only in large blocks called creation units, and it satisfies those redemptions by delivering a basket of portfolio SECURITIES IN KIND to an authorized participant. Because no sale occurs, no gain is realized, and the fund can even use the in-kind delivery to hand out its lowest-basis shares. Ordinary retail selling happens shareholder-to-shareholder on the exchange and never touches the fund at all.

An exchange-traded fund's shares begin trading below the value of the securities the fund holds. Which mechanism tends to close that gap?

1. A.The fund is obliged to buy back shares from any investor at net asset value.Wrong. That describes an open-end fund's redemption right, which retail holders of ETF shares do not have.
2. B.The exchange halts trading until the market price returns to net asset value.Wrong. Exchanges do not halt trading over a discount, and prices are allowed to reflect supply and demand.
3. C.The fund's adviser sells portfolio holdings until the two figures converge.Wrong. Selling holdings would shrink the portfolio and would do nothing to lift the share price.
4. D.Institutions buy the cheap shares and redeem them with the fund for the holdings.Correct. Buying discounted shares and redeeming them for the underlying securities is profitable, and that buying closes the gap.

Why: Exchange-traded funds pair an exchange-traded secondary market with an institutional creation and redemption process, and the second keeps the first honest. When shares trade below the value of the portfolio, an authorized participant can buy them cheaply on the exchange and redeem them with the fund for the underlying securities, capturing the difference. That buying pushes the share price back toward net asset value, and the mirror trade corrects a premium. A closed-end fund has no such mechanism, which is exactly why its discounts can persist for years.
