Macquarie Science and Technology Fund(formerly, Delaware Ivy Science and Technology Fund)

Past performance is not a guarantee of future results. Morningstar proprietary ratings reflect historical risk-adjusted performance as of 03/31/2020. For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating^TM based on a Morningstar Risk-adjusted Return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. Morningstar load-waived ratings do not take into account Class A sales charges. Class A shares without a sales charge (load) are not available to all investors.

The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) The Overall Morningstar Rating for a fund is derived from a weighted average of the performance figures associated with its three-, five-, and ten-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.
