| Factors Affecting Performance [Text Block] | Management's discussion of Performance highlights Macquarie Value ® November 30, 2024. ® ® Top contributors to performance: Holdings in the information technology sector outperformed, specifically positions in the software and communications equipment industries. In the real estate sector, the Fund’s residential real estate investment trust (REIT) holding outperformed the sector more broadly, benefiting from ongoing demand for rental apartments. Strong stock selection in addition to an underweight allocation in the materials sector contributed to performance over the reporting period. The Fund’s underweight allocation in the energy sector compared to its narrowly based index also contributed to performance over the reporting period. Top detractors from performance: Stock selection was the lead detractor from the Fund’s performance over the 12-month reporting period. In the consumer staples sector, the Fund’s holdings underperformed those in the Fund’s narrowly based index in the food products and consumer staples distribution & retail industries. Holdings in the industrials sector underperformed the sector more broadly, especially those with defense industry exposure, which tend to have lower economic sensitivity. Stock selection in the healthcare sector was weak as holdings in the healthcare equipment & supplies and pharmaceutical industries lagged the stronger returns of those in the Fund’s narrowly based index.

Top detractors from performance: Stock selection was the lead detractor from the Fund’s performance over the 12-month reporting period. In the consumer staples sector, the Fund’s holdings underperformed those in the Fund’s narrowly based index in the food products and consumer staples distribution & retail industries. Holdings in the industrials sector underperformed the sector more broadly, especially those with defense industry exposure, which tend to have lower economic sensitivity. Stock selection in the healthcare sector was weak as holdings in the healthcare equipment & supplies and pharmaceutical industries lagged the stronger returns of those in the Fund’s narrowly based index.

Although the Russell 1000 Index can be considered broadly representative of the overall securities market applicable to the Fund, the Fund will continue to show the performance of the Russell 1000 Value Index for comparative purposes because Delaware Management Company, the Fund's manager, believes it is more representative of the Fund's investment universe. |
