The Fund employs a passive investment approach designed to attempt to track the performance of the Index. In seeking its objective, the Fund typically employs a replication strategy, which involves investing in all the securities that make up the Index, in the same proportions as the Index. The Fund will not concentrate (i.e., invest more than 25% of its assets) its investments in a particular industry except to the extent the Index is so concentrated. As of January 31, 2026, the Index was not concentrated in any industry. Note: Standard & Poors SmallCap 600 and S&P SmallCap 600 are trademarks of S&P Global and have been licensed by Principal.
