Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

The Fund's "Principal Investment Strategies" summary section in the Prospectuses is hereby deleted and replaced with the following:

Under normal market conditions, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of mid-capitalization companies. This investment strategy may be changed by the Fund upon 60 days' prior written notice to shareholders. The Fund considers mid-capitalization companies to be those companies with total market capitalizations between $2 billion and $25 billion at the time of initial purchase.

The equity securities in which the Fund may invest include common stocks, preferred stocks, convertible securities, rights and warrants. Preferred stocks are units of ownership in a company that normally have preference over common stock in the payment of dividends and the liquidation of the company. Convertible securities are securities that may be exchanged for, converted into, or exercised to acquire a predetermined number of shares of the company's common stock at the holder's option during a specified time period. A right is a privilege granted to existing shareholders of a company to subscribe to shares of a new issue of common stock before it is issued. Warrants are securities that are usually issued together with a debt security or preferred stock that give the holder the right to buy a proportionate amount of common stock at a specified price.

In selecting investments for the Fund, the Adviser performs fundamental analyses to seek to identify high-quality companies, focusing on the following characteristics:

o Strong balance sheets;

o Competitive advantages;

o High and/or improving financial returns;

o Free cash flow;

o Reinvestment opportunities; and

o Prominent market share positions.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

The last paragraph in the Fund's "Principal Risks" summary section in the Prospectuses is hereby deleted and replaced with the following:

MANAGEMENT RISK - The risk that the investment techniques and risk analyses applied by the Adviser will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to the Adviser and the individual portfolio managers in connection with managing the Fund. There is no guarantee that the investment objective of the Fund will be achieved.

Performance Information

Performance Narrative [Text Block]

The four sentences preceding the bar chart in the Fund's "Performance Information" summary section in the Prospectuses are hereby deleted and replaced with the following:

Prior to February 13, 2012, the Fund employed a different investment strategy and prior to October 1, 2015, the Fund had a sub-adviser. Therefore, the past performance shown below may have differed if the Fund's current investment strategy had been in effect and the Fund did not have a sub-adviser. Of course, the Fund's past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available on the Fund's website at www.frostbank.com or by calling 1-877-71-FROST.
