    <rr:RiskNarrativeTextBlock contextRef="S000075293_NF0531EquityAssetAllocationFundsComboPRO01Member">
            Investing in Other Funds.&#160;The fund bears all risks of investment strategies employed by the underlying funds, including the risk that the underlying
               funds will not meet their investment objectives.



            Stock Market Volatility.&#160;Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or
               economic developments. Different parts of the market, including different market sectors, and different types of securities
               can react differently to these developments.



            Interest Rate Changes.&#160;Interest rate increases can cause the price of a debt security to decrease.



            Foreign Exposure.&#160;Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory,
               market, or economic developments and can perform differently from the U.S. market.



            Prepayment.&#160;The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility
               if interest rates change.



            Issuer-Specific Changes.&#160;The value of an individual security or particular type of security can be more volatile than, and can perform differently
               from, the market as a whole. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending
               transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's
               value or result in delays in recovering securities and/or capital from a counterparty. A decline in the credit quality of
               an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a security
               to decrease.



            Correlation to Index.&#160;The performance of an underlying index fund and its index may vary somewhat due to factors such as fees and expenses of the
               underlying fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions
               to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may
               not be identified and corrected for some period of time, which may have an adverse impact on an underlying fund and its shareholders.



            Passive Management Risk.&#160;Some of the underlying funds in which the fund invests are managed with a passive investment strategy, attempting to track
               the performance of an unmanaged index of securities, regardless of the current or projected performance of an underlying fund's
               index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks
               to outperform a benchmark index. As a result, the performance of these underlying funds could be lower than actively managed
               funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline
               or a decline in the value of one or more issuers. An underlying index fund may be concentrated to approximately the same extent
               that its index concentrates in the securities of issuers in a particular industry or group of industries.



            Leverage Risk.&#160;Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly.



            Securities Lending Risk.&#160;Securities lending involves the risk that the borrower may fail to return the securities loaned in a timely manner or at all.
               If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, an underlying
               fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral.


                  An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation
               or any other government agency.  You could lose money by investing in the fund.

            Investing in Other Funds.&#160;The fund bears all risks of investment strategies employed by the underlying funds, including the risk that the underlying
               funds will not meet their investment objectives.



            Stock Market Volatility.&#160;Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or
               economic developments. Different parts of the market, including different market sectors, and different types of securities
               can react differently to these developments.



            Interest Rate Changes.&#160;Interest rate increases can cause the price of a debt security to decrease.



            Foreign and Emerging Market Risk.&#160;Foreign markets, particularly emerging markets, can be more volatile than the U.S. market due to increased risks of adverse
               issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. The extent
               of economic development; political stability; market depth, infrastructure, and capitalization; and regulatory oversight can
               be less than in more developed markets. Emerging markets typically have less established legal, accounting and financial reporting
               systems than those in more developed markets, which may reduce the scope or quality of financial information available to
               investors. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be
               extremely volatile. Foreign exchange rates also can be extremely volatile.



            Prepayment.&#160;The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility
               if interest rates change.



            Issuer-Specific Changes.&#160;The value of an individual security or particular type of security can be more volatile than, and can perform differently
               from, the market as a whole. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending
               transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's
               value or result in delays in recovering securities and/or capital from a counterparty. A decline in the credit quality of
               an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a security
               to decrease.



            Correlation to Index.&#160;The performance of an underlying index fund and its index may vary somewhat due to factors such as fees and expenses of the
               underlying fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions
               to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may
               not be identified and corrected for some period of time, which may have an adverse impact on an underlying fund and its shareholders.



            Passive Management Risk.&#160;Some of the underlying funds in which the fund invests are managed with a passive investment strategy, attempting to track
               the performance of an unmanaged index of securities, regardless of the current or projected performance of an underlying fund's
               index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks
               to outperform a benchmark index. As a result, the performance of these underlying funds could be lower than actively managed
               funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline
               or a decline in the value of one or more issuers. An underlying index fund may be concentrated to approximately the same extent
               that its index concentrates in the securities of issuers in a particular industry or group of industries.



            Mid Cap Investing.&#160;The value of securities of medium size, less well-known issuers can perform differently from the market as a whole and other
               types of stocks and can be more volatile than that of larger issuers.



            Small Cap Investing.&#160;The value of securities of smaller, less well-known issuers can perform differently from the market as a whole and other types
               of stocks and can be more volatile than that of larger issuers.



            Leverage Risk.&#160;Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly.



            Securities Lending Risk.&#160;Securities lending involves the risk that the borrower may fail to return the securities loaned in a timely manner or at all.
               If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, an underlying
               fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral.


                  An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation
               or any other government agency.  You could lose money by investing in the fund.

            Correlation to Index.&#160;The performance of an underlying index fund and its index may vary somewhat due to factors such as fees and expenses of the
               underlying fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions
               to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may
               not be identified and corrected for some period of time, which may have an adverse impact on an underlying fund and its shareholders.



            Passive Management Risk.&#160;Some of the underlying funds in which the fund invests are managed with a passive investment strategy, attempting to track
               the performance of an unmanaged index of securities, regardless of the current or projected performance of an underlying fund's
               index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks
               to outperform a benchmark index. As a result, the performance of these underlying funds could be lower than actively managed
               funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline
               or a decline in the value of one or more issuers. An underlying index fund may be concentrated to approximately the same extent
               that its index concentrates in the securities of issuers in a particular industry or group of industries.



            Mid Cap Investing.&#160;The value of securities of medium size, less well-known issuers can perform differently from the market as a whole and other
               types of stocks and can be more volatile than that of larger issuers.



            Small Cap Investing.&#160;The value of securities of smaller, less well-known issuers can perform differently from the market as a whole and other types
               of stocks and can be more volatile than that of larger issuers.



            Leverage Risk.&#160;Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly.



            Securities Lending Risk.&#160;Securities lending involves the risk that the borrower may fail to return the securities loaned in a timely manner or at all.
               If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, an underlying
               fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral.


                  An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation
               or any other government agency.  You could lose money by investing in the fund.

            Investing in Other Funds.&#160;The fund bears all risks of investment strategies employed by the underlying funds, including the risk that the underlying
               funds will not meet their investment objectives.



            Stock Market Volatility.&#160;Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or
               economic developments. Different parts of the market, including different market sectors, and different types of securities
               can react differently to these developments.



            Interest Rate Changes.&#160;Interest rate increases can cause the price of a debt security to decrease.



            Foreign and Emerging Market Risk.&#160;Foreign markets, particularly emerging markets, can be more volatile than the U.S. market due to increased risks of adverse
               issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. The extent
               of economic development; political stability; market depth, infrastructure, and capitalization; and regulatory oversight can
               be less than in more developed markets. Emerging markets typically have less established legal, accounting and financial reporting
               systems than those in more developed markets, which may reduce the scope or quality of financial information available to
               investors. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be
               extremely volatile. Foreign exchange rates also can be extremely volatile.



            Prepayment.&#160;The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility
               if interest rates change.



            Issuer-Specific Changes.&#160;The value of an individual security or particular type of security can be more volatile than, and can perform differently
               from, the market as a whole. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending
               transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's
               value or result in delays in recovering securities and/or capital from a counterparty. A decline in the credit quality of
               an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a security
               to decrease.



            Correlation to Index.&#160;The performance of an underlying index fund and its index may vary somewhat due to factors such as fees and expenses of the
               underlying fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions
               to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may
               not be identified and corrected for some period of time, which may have an adverse impact on an underlying fund and its shareholders.



            Passive Management Risk.&#160;Some of the underlying funds in which the fund invests are managed with a passive investment strategy, attempting to track
               the performance of an unmanaged index of securities, regardless of the current or projected performance of an underlying fund's

               that its index concentrates in the securities of issuers in a particular industry or group of industries.



            Mid Cap Investing.&#160;The value of securities of medium size, less well-known issuers can perform differently from the market as a whole and other
               types of stocks and can be more volatile than that of larger issuers.



            Small Cap Investing.&#160;The value of securities of smaller, less well-known issuers can perform differently from the market as a whole and other types
               of stocks and can be more volatile than that of larger issuers.



            Leverage Risk.&#160;Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly.
