Fund profile
As filed in the prospectus · 2026 Q2
The investment objective of the Fund (Fund or Feeder Fund) is to track the performance of the S&P MidCap 400 Index to provide long-term capital growth by investing in equity securities of medium capitalization-weighted domestic corporations through exclusive investment in shares of the JNL Mid Cap Index Fund (Master Fund).
The fund operates as a feeder that invests exclusively in a master fund tracking the S&P MidCap 400 Index through representative sampling, holding stocks in proportion to their index weights. Because the master fund samples rather than holds all index constituents, its performance may diverge from the index. The master fund may also use exchange-traded funds, cash, and financial futures to assist with rebalancing and meet redemptions.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
May 2026 and Jun 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
This fund changed legal form during the period shown. The history above is continuous — it spans both eras, and the change is not a gap in reporting.
