Principal Real Estate Securities Fund 

Under typical conditions, this fund commits a minimum of 80% of its total net assets, alongside any borrowed capital used for investment, to the stock holdings of companies primarily operating within the real estate sector when the securities are purchased. It does not limit its equity investments based on the market capitalization of these companies, considering small, medium, and large-sized firms. The fund explicitly concentrates its portfolio within the real estate industry, meaning over 25% of its net assets are directed towards real estate securities. Consequently, it is categorized as a non-diversified investment vehicle.
