to the Prospectuses dated August 29, 2019, as supplemented

(the “Prospectuses”)

Capitalized terms and certain other terms used in this Supplement, unless otherwise defined in this Supplement, have the meanings assigned to them in the Prospectuses.

The following change is effective immediately. In the “Description of the Principal Risks of the Funds” section of the Prospectuses, “Market Risk” is deleted in its entirety and replaced with the following:

Market Risk

The value of a Fund’s investments may fluctuate and/or decline because of changes in the markets in which the Fund invests, which could cause the Fund to underperform other funds with similar investment objectives and strategies. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments. Changes in these markets may be rapid and unpredictable. Fluctuations in the markets generally or in a specific industry or sector may impact the securities in which a Fund invests. From time to time, markets may experience periods of stress for potentially prolonged periods that may result in: (i) increased market volatility; (ii) reduced market liquidity; and (iii) increased redemptions of Fund shares. Such conditions may add significantly to the risk of volatility in the net asset value of a Fund’s shares and the market prices at which shares of a Fund trade on a securities exchange. During periods of market stress shares of a Fund may also experience significantly wider “bid/ask” spreads and premiums and discounts between a Fund’s net asset value and market price.

Market changes may impact equity and fixed income securities in different and, at times, conflicting manners. A Fund potentially will be prevented from executing investment decisions at an advantageous time or price as a result of any domestic or global market disruptions, particularly disruptions causing heightened market volatility and reduced market liquidity, as well as increased or changing regulations or market closures. Thus, investments that the Advisor or Subadvisor believes best enable a Fund to track the performance of its Underlying Index may be unavailable entirely or in the specific quantities sought by the Advisor or Subadvisor and the Fund may need to obtain the exposure through less advantageous or indirect investments or forgo the investment at the time. Securities and investments included as components of an Underlying Index may be susceptible to declines in value, including declines in value that are not believed to be representative of the issuer’s value or fundamentals, due to investor reactions to such events.  In response to market volatility and disruption, an Underlying Index may delay rebalancing, implement temporary or permanent modifications to its methodology or take other actions.

Political and diplomatic events within the United States and abroad, such as the U.S. budget and deficit reduction plans, protectionist measures, trade tensions central bank policy and government intervention in the economy, has in the past resulted, and may in the future result, in developments that present additional risks to a Fund's investments and operations. Geopolitical and other events, such as war, acts of terrorism, natural disasters, the spread of infectious illnesses, epidemics and pandemics, environmental and other public health issues, recessions or other events, and governments’ reactions to such events, may lead to increased market volatility and instability in world economies and markets generally and may have adverse effects on the performance of a Fund and its investments. Additional and/or prolonged geopolitical or other events may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. Any such market, economic and other disruptions could also prevent a Fund from executing its investment strategies and processes in a timely manner.

An investment in a Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your Shares, they could be worth less than what you paid for them.
