Management's discussion of Fund performance
Performance highlights
Macquarie Small Cap Core Fund (Class R6) returned 33.22% (excluding sales charge) for the 12 months ended November 30, 2024. During the same period, the Russell 3000® Index, the Fund's broad-based securities market index, returned 34.49%, while the Russell 2000® Index, the Fund's narrowly based securities market index, returned 36.43%.
Top contributors to performance:
Stock selection was strongest within the consumer services sector. Brinker International Inc., operator of Chili’s and Maggiano’s restaurants, contributed the most.
Holdings in the financials sector outperformed. Within the sector, stocks owned in the insurance and asset management industries were the largest contributors.
Holdings in the consumer discretionary sector outperformed over the period.
Top detractors from performance:
The technology sector detracted the most from performance. A lack of exposure to Super Micro Computer Inc. detracted meaningfully from relative performance.
Holdings in the transportation sector underperformed. Ship freight, airlines, and trucking industries all detracted from performance.
Stock selection in the consumer staples sector underperformed.

Management's discussion of Fund performance
Performance highlights
Macquarie Small Cap Value Fund (Institutional Class) returned 33.48% (excluding sales charge) for the 12 months ended November 30, 2024. During the same period, the Russell 3000® Index, the Fund's broad-based securities market index, returned 34.49%, while the Russell 2000® Value Index, the Fund's narrowly based securities market index, returned 32.55%.
Top contributors to performance:
Stock selection was the most significant contributor to the Fund’s outperformance over the period.
Holdings in the financial services sector outperformed. Within the sector, stocks owned in the capital markets, banks, and insurance industries were the largest contributors.
Strong stock selection and a relative underweight allocation in the healthcare sector contributed.
Holdings in the consumer discretionary sector outperformed over the period. The Fund’s positions in the hotels, restaurants, and leisure industry contributed.
Top detractors from performance:
Holdings in the basic industry sector lagged the stronger performance of the sector in the benchmark.
Holdings in the energy sector underperformed. Companies in the energy equipment and services industry detracted. The energy sector was the only sector in the Fund to decline for the period as the price of oil fell due to excess supply.
Stock selection in the industrials sector detracted from performance as holdings in the electrical equipment and machinery industries underperformed.

Performance Table Market Index Changed [Text Block] In connection with new regulatory requirements, effective the date of this report, the Fund changed its broad-based securities market benchmark index to the Russell 3000 Index.
Prior Market Index Comparison [Text Block] Although the Russell 3000 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 2000 Value Index for comparative purposes because Delaware Management Company, the Fund's manager, believes it is more representative of the Fund's investment universe.
