AI LARGE CAP GROWTH FUND CLASS C (LGNCX) Exchange: NMFQS

DELISTED - Principal Strategies. The Fund seeks long-term capital appreciation by investing at least 80% of its assets in common stocks of large-cap U.S. companies, at the time of purchase. A large cap company is defined as a company that has a market capitalization found within the Russell 1000® Index (between $1.98 billion and $550 billion at the time of its most recent reconstitution on May 27, 2016) at the time of purchase. The size of the companies in the Russell 1000® Index will change with market conditions. While the Fund’s investments will consist primarily of domestic securities, the Fund may also invest its net assets in sponsored or unsponsored depositary receipts and securities of foreign companies that are traded on U.S. stock exchanges.   Under normal market conditions, the Fund:   Ø Will invest at least 80% of the Fund's net assets, plus any borrowings for investment purposes, in U.S. large-cap companies.   Ø May invest up to 20% of the Fund’s net assets, plus any borrowings in equity securities of foreign issuers, through Depositary Receipts and similar investments that are traded on a U.S. stock exchange. Depositary receipts are issued by a bank that purchases shares of a non-U.S. company and issues shares based on the foreign holdings. Sponsored depositary receipts are organized with the cooperation of the issuer of the underlying securities. Unsponsored depositary receipts are organized independently, without the cooperation of the issuer of the underlying securities. Types of depositary receipts include American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”). ADRs trade on a U.S. exchange and thus are subject to registration and disclosure requirements under the Securities Act of 1933 and Securities Exchange Act of 1934, each as amended, and GDRs trade on the London Stock Exchange.   Ø May invest up to 20% of the Fund's net assets, plus any borrowings for investment purposes, in mid-cap companies.   Ø May invest up to 10% of its total assets in the securities of one company.   The Adviser seeks to identify and select inefficiently priced securities with strong appreciation potential by employing a fundamentally-based quantitative security ranking method in conjunction with a portfolio optimizer that attempts to maximize prospective returns while controlling volatility of returns. Securities are ranked primarily on the basis of a pattern recognition algorithm that uses recent and historical data from the financial reports of the target companies to predict relative returns of a mid- to large-cap universe of equity securities. The optimizer uses these forecasted relative returns along with actual historical return data for estimating portfolio return volatility.   The Fund is non-diversified, meaning that it may invest a significant percentage of its assets in the securities of one issuer. In addition, the Fund may focus on a particular market sector or sectors. The Fund may invest up to 10% of its total assets in the securities of one company. The Fund may also engage in frequent and active trading as part of its principal investment strategy.   Main types of securities the Fund may hold:   Ø Common stocks of U.S. companies, including real estate investment trusts (“REITs”)   Ø ADRs and GDRs   Ø Short term money market securities, including cash, money market mutual funds and Treasury Bills
