U.S. Large Cap Equity Portfolio

Risk Table - U.S. Large Cap Equity Portfolio	Risk [Text Block]
Principal Risks	Principal Risks Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a description of principal risks of investing in the Portfolio.
Risk Lose Money [Member]	Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money.
Risk Not Insured [Member]	An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Equity Market Risk	Equity Market Risk: Even a long-term investment approach cannot guarantee a profit. Economic, market, political, and issuer-specific conditions and events will cause the value of equity securities, and a fund that owns them, to rise or fall. Stock markets are volatile, with periods of rising prices and periods of falling prices.
Profitability Investment Risk	Profitability Investment Risk: High relative profitability stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause a fund to at times underperform equity funds that use other investment strategies.
Value Investment Risk	Value Investment Risk: Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause a fund to at times underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic, and industry developments than the market as a whole and other types of stocks. Value stocks also may underperform the market for long periods of time.
Derivatives Risk	Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.
Securities Lending Risk	Securities Lending Risk: Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover the securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences.
Operational Risk	Operational Risk: Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes. Various operational events or circumstances are outside a fund’s or its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce these operational risks through controls and procedures. However, measures that seek to reduce these operational risks through controls and procedures may not address every possible risk and may be inadequate to address these risks.
Cyber Security Risk	Cyber Security Risk: A fund and its service providers’ use of internet, technology and information systems may expose the fund to potential risks linked to cyber security breaches of those technological or information systems. Cyber security breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information, customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational functionality. The following is a description of additional principal risks of investing in the ETF Class shares of the Portfolio, due to the shares being listed and traded on a national securities exchange.
Market Trading Risk	Market Trading Risk: Active trading markets for the ETF Class shares may not be developed or maintained by market makers or authorized participants. Authorized participants are not obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less liquid in response to deteriorating liquidity in the markets for a fund’s portfolio holdings, which may cause a significant variance in the market price of the ETF Class shares and their underlying value as well as an increase in the ETF Class shares’ bid-ask spread.
Premium/Discount Risk	Premium/Discount Risk: The net asset value (“NAV”) of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund’s holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Value Investment Risk	Value Investment Risk: Value stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause a fund to at times underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic, and industry developments than the market as a whole and other types of stocks. Value stocks also may underperform the market for long periods of time.
Derivatives Risk	Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.
Securities Lending Risk	Securities Lending Risk: Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover the securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences.
Operational Risk	Operational Risk: Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes. Various operational events or circumstances are outside a fund’s or its advisor’s control, including instances at third parties. A fund and its advisor seek to reduce these operational risks through controls and procedures. However, measures that seek to reduce these operational risks through controls and procedures may not address every possible risk and may be inadequate to address these risks.
Cyber Security Risk	Cyber Security Risk: A fund and its service providers’ use of internet, technology and information systems may expose the fund to potential risks linked to cyber security breaches of those technological or information systems. Cyber security breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information, customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational functionality. The following is a description of additional principal risks of investing in the ETF Class shares of the Portfolio, due to the shares being listed and traded on a national securities exchange.
Market Trading Risk	Market Trading Risk: Active trading markets for the ETF Class shares may not be developed or maintained by market makers or authorized participants. Authorized participants are not obligated to make a market in the ETF Class shares or to submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of the ETF Class shares will continue to be met. Additionally, in stressed market conditions, the market for the ETF Class shares may become less liquid in response to deteriorating liquidity in the markets for a fund’s portfolio holdings, which may cause a significant variance in the market price of the ETF Class shares and their underlying value as well as an increase in the ETF Class shares’ bid-ask spread.
Premium/Discount Risk	Premium/Discount Risk: The net asset value (“NAV”) of the ETF Class shares and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund’s holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Risks of Concentrating in the Real Estate Industry	Risks of Concentrating in the Real Estate Industry: A fund that concentrates (i.e., invests more than 25% of its net assets) its investments in securities of companies in the real estate industry will be exposed to the general risks of direct real estate ownership. The value of securities in the real estate industry can be affected by changes in real estate values and rental income, property taxes, and tax and regulatory requirements. Also, the value of securities in the real estate industry may decline with changes in interest rates. Investing in REITs and REIT-like entities involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. REITs and REIT-like entities are dependent upon management skill, may not be diversified, and are subject to heavy cash flow dependency and self-liquidation. REITs and REIT-like entities also are subject to the possibility of failing to qualify for tax free pass-through of income. Also, because REITs and REIT-like entities typically are invested in a limited number of projects or in a particular market segment, these entities are more susceptible to adverse developments affecting a single project or market segment than more broadly diversified investments. The performance of a fund may be materially different from the broad equity market.
