Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE
The Fund seeks to generate high monthly income while providing reduced downside risk, primarily by gaining exposure to a daily laddered portfolio of synthetic autocallable positions referencing the Bloomberg US Large Cap VolMax Autocallable Index.

Income earned on the Fund’s U.S. Treasury collateral also contributed to results.
