| Factors Affecting Performance [Text Block] | How did the Fund perform during the last six months and what affected its performance? The share class had a 0.00% total return in the six months ended June 30, 2024, compared with the Linked Index, 1 Stock selection in the data center sector contributed to relative performance in the period. An overweight position in Digital Realty Trust aided performance, outperforming the index amid strong demand for the company's services, including Cloud and Artificial Intelligence capabilities. Stock selection and an overweight in specialty REITs also helped performance, due primarily to an overweight position in Iron Mountain. The stock had a large gain, benefiting from strong pricing power and the company's continued expansion into data center operations. Stock selection and an underweight in offices further aided performance. An overweight in Highwoods Properties, the portfolio's sole office allocation in the period, performed well. An underweight allocation to apartment owners detracted from relative performance. The sector outperformed broader REITs amid better-than-expected fundamentals, particularly in coastal markets. Stock selection in the free-standing retail sectors also hindered performance, due mainly to an overweight in Realty Income. The holding, which tends to be sensitive to moves in interest rates, declined amid a rise in bond yields in the period. Stock selection in shopping centers was a modest detractor from relative returns; an overweight position in Kimco Realty underperformed.
