BGLD uses FLEX options, short-term Treasurys and cash-like investments in an effort to moderate losses on price movement on the SPDR Gold Trust ETF (ticker: GLD) over a three-month period. For tax purposes, the fund does not hold the FLEX options or gold directly but gets its exposure through a wholly-owned Cayman Island subsidiary. BGLD compensates for GLDs losses between 5% and 15%, beyond it, the fund will experience all subsequent losses on a one-to-one basis. In exchange for preventing realization of GLDs losses, investors forego upside participation above a certain threshold, which is reset quarterly. Investors who buy at any other time than the quarterly reset day may have a very different protection and buffer zone. The issuer publishes effective interim levels daily on its website. The fund must be held to the end of the period to achieve the intended results. The targeted buffers and caps do not include the funds expense ratio.
