UDEC uses options in an effort to moderate losses on the S&P 500 over a one-year period starting each December. The fund foregoes some upside return as well as the S&P 500s dividend component, because the options are written on the price (not total) return version of the index. In exchange for buffering losses between -5% and -30% of the S&P 500, investors forego upside participation above a certain threshold, which is reset annually. Investors who buy at any other time than the annual 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. The fund is actively managed, resets annually and uses FLEX options exclusively.
