The principal risks of investing in the Aggressive Growth Portfolio are summarized below.</p><ul><li><i>Market Risk.</i> Conditions in a broad or specialized market, a sector thereof or an individual industry may adversely affect security prices, thereby reducing the value of a fund’s investments.</li></ul><ul><li><i>Allocation Risk.</i> The allocation techniques and decisions of Morningstar Associates, LLC may not produce the desired results. </li></ul><ul><li><i>Growth Securities Risk.</i> Growth (equity) securities typically trade at higher multiples of current earnings than other securities. Therefore, the values of growth securities may be more sensitive to changes in current or expected earnings than the values of other securities.</li></ul><ul><li><i>Small- and Medium-Sized Company Risk.</i> Securities of small- and medium-sized companies may have less liquidity and more volatile prices than securities of larger companies, which can make it difficult for the Fund to sell such securities at desired times or prices. </li></ul><ul><li><i>Value Securities Risk.</i> Value securities are securities the Adviser and/or a Sleeve Subadviser believes are selling at a price lower than their true value, perhaps due to adverse business developments or special risks. If that belief is wrong or remains unrecognized by the market, the price of the securities may decline or may not appreciate as anticipated.</li></ul><ul><li><i>Non-U. S. Securities Risk.</i> Non-U.S. securities may have less liquidity and more volatile prices than domestic securities, which can make it difficult for the Fund to sell such securities at desired times or prices. Non-U.S. markets may differ from U.S. markets in material and adverse ways. For example, securities transaction expenses generally are higher, transaction settlement may be slower, recourse in the event of default may be more limited and taxes and currency exchange controls may limit amounts available for distribution to shareholders. Non-U.S. investments are also subject to the effects of local political, social, diplomatic or economic events.</li></ul><ul><li><i>Emerging Markets Securities Risk.</i> Emerging market securities are likely to have greater exposure to Non-U.S. Securities Risk. In addition, emerging markets generally have less developed economies and securities markets, are more prone to rapid social, political and economic changes, have a higher risk of currency devaluation and have more volatile inflation rates than more developed countries. </li></ul><ul><li><i> Multi-Manager Risk.</i> Because each Sleeve Subadviser makes independent investment decisions, such investment decisions may not complement one another, leading to unintended results. The use of multiple Sleeve Subadvisers may lead to higher portfolio turnover rates, higher transactions costs and/or disadvantageous tax consequences.</li></ul><ul><li><i> Turnover Risk.</i> Frequent changes in the securities held by a Fund increases the Fund’s transaction costs and may result in adverse tax consequences, which together may adversely affect the Fund’s performance. </li></ul><ul><li><i>Acquired Funds Risk.</i> Investments in shares of other investment companies (“acquired funds”) are subject to the fees, expenses and risks of those acquired funds. The Fund may be limited in the extent to which it can invest in an acquired fund, and may have limited information about the acquired fund’s investments, either of which may adversely affect the management of the Fund.

The principal risks of investing in the Growth Portfolio are summarized below.</p><ul><li><i>Market Risk.</i> Conditions in a broad or specialized market, a sector thereof or an individual industry may adversely affect security prices, thereby reducing the value of a fund’s investments.</li></ul><ul><li><i>Interest Rate Risk.</i> The value of debt securities tends to decrease when nominal interest rates rise. Longer-duration securities tend to be more sensitive to interest rate changes, and thus more volatile, than shorter-duration securities.</li></ul><ul><li><i>Credit Risk.</i> Changing economic conditions may adversely affect an obligated entity’s actual or perceived ability to pay interest or principal on a fixed income security when due, which in turn can adversely affect the price of or income derived from the security.</li></ul><ul><li><i> Allocation Risk.</i> The allocation techniques and decisions of Morningstar Associates, LLC may not produce the desired results.</li></ul><ul><li><i> U.S. Government Securities Risk.</i> U.S. government securities that are not issued or guaranteed by the U.S. Treasury are generally more susceptible to loss than are securities that are so issued or guaranteed.</li></ul><ul><li><i>Mortgage Risk.</i> Mortgage related securities tend to become more sensitive to interest rate changes as interest rates rise, increasing their volatility. When interest rates decline, underlying borrowers may pay off their loans sooner than expected, forcing the fund to reinvest disposition proceeds at lower prevailing interest rates. </li></ul><ul><li><i>Reinvestment Risk.</i> Income from the fixed income portion of a fund’s investments may decline if the fund is forced to invest the proceeds from matured, called or otherwise disposed of debt securities or convertible securities at interest rates that are below the fund’s earnings rate at that time. </li></ul><ul><li><i>Growth Securities Risk.</i> Growth (equity) securities typically trade at higher multiples of current earnings than other securities. Therefore, the values of growth securities may be more sensitive to changes in current or expected earnings than the values of other securities.</li></ul><ul><li><i>Small- and Medium-Sized Company Risk.</i> Securities of small- and medium-sized companies may have less liquidity and more volatile prices than securities of larger companies, which can make it difficult for the Fund to sell such securities at desired times or prices.</li></ul><ul><li><i>High Yield Securities Risk.</i> High yield securities (“junk bonds”) are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments when due. Investments in such securities tend to increase the Fund’s exposure to interest rate risk, credit risk and liquidity risk.</li></ul><ul><li><i>Value Securities Risk.</i> Value securities are securities the Adviser and/or a Sleeve Subadviser believes are selling at a price lower than their true value, perhaps due to adverse business developments or special risks. If that belief is wrong or remains unrecognized by the market, the price of the securities may decline or may not appreciate as anticipated.</li></ul><ul><li><i> Non-U. S. Securities Risk.</i> Non-U.S. securities may have less liquidity and more volatile prices than domestic securities, which can make it difficult for the Fund to sell such securities at desired times or prices. Non-U.S. markets may differ from U.S. markets in material and adverse ways. For example, securities transaction expenses generally are higher, transaction settlement may be slower, recourse in the event of default may be more limited and taxes and currency exchange controls may limit amounts available for distribution to shareholders. Non-U.S. investments are also subject to the effects of local political, social, diplomatic or economic events.</li></ul><ul><li><i>Emerging Markets Securities Risk.</i> Emerging market securities are likely to have greater exposure to Non-U.S. Securities Risk. In addition, emerging markets generally have less developed economies and securities markets, are more prone to rapid social, political and economic changes, have a higher risk of currency devaluation and have more volatile inflation rates than more developed countries.</li></ul><ul><li><i> Multi-Manager Risk.</i> Because each Sleeve Subadviser makes independent investment decisions, such investment decisions may not complement one another, leading to unintended results. The use of multiple Sleeve Subadvisers may lead to higher portfolio turnover rates, higher transactions costs and/or disadvantageous tax consequences.</li></ul><ul><li><i> Turnover Risk.</i> Frequent changes in the securities held by a Fund increases the Fund’s transaction costs and may result in adverse tax consequences, which together may adversely affect the Fund’s performance.</li></ul><ul><li><i> Inflation-Linked Security Risk.</i> The price of an inflation-linked security tends to decrease when real interest rates increase and can increase when real interest rates decrease, and its interest payments are unpredictable. The inflation index used may not accurately measure the real inflation rate, which may cause the value of the securities to decline. Relevant pricing indices also may be discontinued, fundamentally altered in an adverse manner or substituted with alternative indices.</li></ul><ul><li><i> Acquired Funds Risk.</i> Investments in shares of other investment companies (“acquired funds”) are subject to the fees, expenses and risks of those acquired funds. The Fund may be limited in the extent to which it can invest in an acquired fund, and may have limited information about the acquired fund’s investments, either of which may adversely affect the management of the Fund. If an acquired fund seeks to track the performance of an index, the value of the Fund’s investment in such acquired fund also would fluctuate with the value of the index.</li></ul><p>The foregoing descriptions are only summaries.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

Longer-duration securities tend to be more sensitive to interest rate changes, and thus more volatile, than shorter-duration securities.</li></ul><ul><li><i> Credit Risk.</i> Changing economic conditions may adversely affect an obligated entity’s actual or perceived ability to pay interest or principal on a fixed income security when due, which in turn can adversely affect the price of or income derived from the security.</li></ul><ul><li><i>Allocation Risk.</i> The allocation techniques and decisions of Morningstar Associates, LLC may not produce the desired results.</li></ul><ul><li><i> U.S. Government Securities Risk.</i> U.S. government securities that are not issued or guaranteed by the U.S. Treasury are generally more susceptible to loss than are securities that are so issued or guaranteed.</li></ul><ul><li><i>Mortgage Risk.</i> Mortgage related securities tend to become more sensitive to interest rate changes as interest rates rise, increasing their volatility. When interest rates decline, underlying borrowers may pay off their loans sooner than expected, forcing the fund to reinvest disposition proceeds at lower prevailing interest rates.</li></ul><ul><li><i>Reinvestment Risk.</i> Income from the fixed income portion of a fund’s investments may decline if the fund is forced to invest the proceeds from matured, called or otherwise disposed of debt securities or convertible securities at interest rates that are below the fund’s earnings rate at that time.</li></ul><ul><li><i> Growth Securities Risk.</i> Growth (equity) securities typically trade at higher multiples of current earnings than other securities. Therefore, the values of growth securities may be more sensitive to changes in current or expected earnings than the values of other securities.</li></ul><ul><li><i>Small- and Medium-Sized Company Risk.</i> Securities of small- and medium-sized companies may have less liquidity and more volatile prices than securities of larger companies, which can make it difficult for the Fund to sell such securities at desired times or prices.</li></ul><ul><li><i> High Yield Securities Risk.</i> High yield securities (“junk bonds”) are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments when due. Investments in such securities tend to increase the Fund’s exposure to interest rate risk, credit risk and liquidity risk.</li></ul><ul><li><i>Value Securities Risk.</i> Value securities are securities the Adviser and/or a Sleeve Subadviser believes are selling at a price lower than their true value, perhaps due to adverse business developments or special risks. If that belief is wrong or remains unrecognized by the market, the price of the securities may decline or may not appreciate as anticipated.</li></ul><ul><li><i> Non-U. S. Securities Risk.</i> Non-U.S. securities may have less liquidity and more volatile prices than domestic securities, which can make it difficult for the Fund to sell such securities at desired times or prices. Non-U.S. markets may differ from U.S. markets in material and adverse ways. For example, securities transaction expenses generally are higher, transaction settlement may be slower, recourse in the event of default may be more limited and taxes and currency exchange controls may limit amounts available for distribution to shareholders. Non-U.S. investments are also subject to the effects of local political, social, diplomatic or economic events.</li></ul><ul><li><i>Emerging Markets Securities Risk.</i> Emerging market securities are likely to have greater exposure to Non-U.S. Securities Risk. In addition, emerging markets generally have less developed economies and securities markets, are more prone to rapid social, political and economic changes, have a higher risk of currency devaluation and have more volatile inflation rates than more developed countries.</li></ul><ul><li><i> Multi-Manager Risk.</i> Because each Sleeve Subadviser makes independent investment decisions, such investment decisions may not complement one another, leading to unintended results. The use of multiple Sleeve Subadvisers may lead to higher portfolio turnover rates, higher transactions costs and/or disadvantageous tax consequences.</li></ul><ul><li><i>Turnover Risk.</i> Frequent changes in the securities held by a Fund increases the Fund’s transaction costs and may result in adverse tax consequences, which together may adversely affect the Fund’s performance.</li></ul><ul><li><i> Inflation-Linked Security Risk.</i> The price of an inflation-linked security tends to decrease when real interest rates increase and can increase when real interest rates decrease, and its interest payments are unpredictable. The inflation index used may not accurately measure the real inflation rate, which may cause the value of the securities to decline. Relevant pricing indices also may be discontinued, fundamentally altered in an adverse manner or substituted with alternative indices.</li></ul><ul><li><i>Acquired Funds Risk.</i> Investments in shares of other investment companies (“acquired funds”) are subject to the fees, expenses and risks of those acquired funds. The Fund may be limited in the extent to which it can invest in an acquired fund, and may have limited information about the acquired fund’s investments, either of which may adversely affect the management of the Fund. If an acquired fund seeks to track the performance of an index, the value of the Fund’s investment in such acquired fund also would fluctuate with the value of the index.</li></ul><p>The foregoing descriptions are only summaries. Please see “Principal Risks” on page 39 for more detailed descriptions of the foregoing risks.</p><p>As with all mutual funds, investors may lose money by investing in the Moderate Portfolio.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Conservative Portfolio may invest up to 100% of its total assets in fixed income securities and up to 50% of its total assets in equity securities. The Conservative Portfolio may invest up to 40% of its total assets in securities of non-U.S. issuers including investments in emerging markets, though it is not currently anticipated that the Conservative Portfolio would invest more than 10% of its total assets in emerging market securities. Over the longer term, relative to the other ESG Managers™ Portfolios, the Conservative Portfolio should offer shareholders the potential for a medium to high level of income and a low to medium level of capital growth.</p><p>The Conservative Portfolio uses multiple subadvisers (“Sleeve Subadvisers”) to implement its principal investment strategies. The Conservative Portfolio has engaged Morningstar Associates, LLC as a portfolio construction adviser to design an asset allocation strategy. Morningstar Associates allocates portions of the Conservative Portfolio’s assets (referred to as “sleeves”) to one or more of the Sleeve Subadvisers, who manage their respective sleeves under the general supervision of the Adviser and Morningstar Associates. Morningstar Associates also may allocate a portion of the Conservative Portfolio’s assets to one or more investments, such as mutual funds or ETFs, that are not managed by a sleeve subadviser. Morningstar Associates may adjust its allocations from time to time. Most of the Sleeve Subadvisers apply their own sustainability or environmental, social and governance (ESG) criteria to their investments. The Adviser applies its own ESG criteria to the investments of those Sleeve Subadvisers that do not have their own ESG criteria.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

The principal risks of investing in the Conservative Portfolio are summarized below.</p><ul><li><i>Market Risk.</i> Conditions in a broad or specialized market, a sector thereof or an individual industry may adversely affect security prices, thereby reducing the value of a fund’s investments.</li></ul><ul><li><i>Interest Rate Risk.</i> The value of debt securities tends to decrease when nominal interest rates rise. Longer-duration securities tend to be more sensitive to interest rate changes, and thus more volatile, than shorter-duration securities.</li></ul><ul><li><i>Credit Risk.</i> Changing economic conditions may adversely affect an obligated entity’s actual or perceived ability to pay interest or principal on a fixed income security when due, which in turn can adversely affect the price of or income derived from the security.</li></ul><ul><li><i> Allocation Risk.</i> The allocation techniques and decisions of Morningstar Associates, LLC may not produce the desired results.</li></ul><ul><li><i>U.S. Government Securities Risk.</i> U.S. government securities that are not issued or guaranteed by the U.S. Treasury are generally more susceptible to loss than are securities that are so issued or guaranteed.</li></ul><ul><li><i>Mortgage Risk.</i> Mortgage related securities tend to become more sensitive to interest rate changes as interest rates rise, increasing their volatility. When interest rates decline, underlying borrowers may pay off their loans sooner than expected, forcing the fund to reinvest disposition proceeds at lower prevailing interest rates.</li></ul><ul><li><i>Reinvestment Risk.</i> Income from the fixed income portion of a fund’s investments may decline if the fund is forced to invest the proceeds from matured, called or otherwise disposed of debt securities or convertible securities at interest rates that are below the fund’s earnings rate at that time.</li></ul><ul><li><i> Growth Securities Risk.</i> Growth (equity) securities typically trade at higher multiples of current earnings than other securities. Therefore, the values of growth securities may be more sensitive to changes in current or expected earnings than the values of other securities.</li></ul><ul><li><i>Small- and Medium-Sized Company Risk.</i> Securities of small- and medium-sized companies may have less liquidity and more volatile prices than securities of larger companies, which can make it difficult for the Fund to sell such securities at desired times or prices.</li></ul><ul><li><i> High Yield Securities Risk.</i> High yield securities (“junk bonds”) are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments when due. Investments in such securities tend to increase the Fund’s exposure to interest rate risk, credit risk and liquidity risk.</li></ul><ul><li><i>Value Securities Risk.</i> Value securities are securities the Adviser and/or a Sleeve Subadviser believes are selling at a price lower than their true value, perhaps due to adverse business developments or special risks. If that belief is wrong or remains unrecognized by the market, the price of the securities may decline or may not appreciate as anticipated.</li></ul><ul><li><i>Non-U. S. Securities Risk.</i> Non-U.S. securities may have less liquidity and more volatile prices than domestic securities, which can make it difficult for the Fund to sell such securities at desired times or prices. Non-U.S. markets may differ from U.S. markets in material and adverse ways. For example, securities transaction expenses generally are higher, transaction settlement may be slower, recourse in the event of default may be more limited and taxes and currency exchange controls may limit amounts available for distribution to shareholders. Non-U.S. investments are also subject to the effects of local political, social, diplomatic or economic events.</li></ul><ul><li><i>Emerging Markets Securities Risk.</i> Emerging market securities are likely to have greater exposure to Non-U.S. Securities Risk. In addition, emerging markets generally have less developed economies and securities markets, are more prone to rapid social, political and economic changes, have a higher risk of currency devaluation and have more volatile inflation rates than more developed countries.</li></ul><ul><li><i>Multi-Manager Risk.</i> Because each Sleeve Subadviser makes independent investment decisions, such investment decisions may not complement one another, leading to unintended results. The use of multiple Sleeve Subadvisers may lead to higher portfolio turnover rates, higher transactions costs and/or disadvantageous tax consequences.</li></ul><ul><li><i>Turnover Risk.</i> Frequent changes in the securities held by a Fund increases the Fund’s transaction costs and may result in adverse tax consequences, which together may adversely affect the Fund’s performance.</li></ul><ul><li><i>Inflation-Linked Security Risk.</i> The price of an inflation-linked security tends to decrease when real interest rates increase and can increase when real interest rates decrease, and its interest payments are unpredictable. The inflation index used may not accurately measure the real inflation rate, which may cause the value of the securities to decline. Relevant pricing indices also may be discontinued, fundamentally altered in an adverse manner or substituted with alternative indices.</li></ul><ul><li><i> Acquired Funds Risk.</i>Investments in shares of other investment companies (“acquired funds”) are subject to the fees, expenses and risks of those acquired funds. The Fund may be limited in the extent to which it can invest in an acquired fund, and may have limited information about the acquired fund’s investments, either of which may adversely affect the management of the Fund. If an acquired fund seeks to track the performance of an index, the value of the Fund’s investment in such acquired fund also would fluctuate with the value of the index.</li></ul><p>The foregoing descriptions are only summaries. Please see “Principal Risks” on page 39 for more detailed descriptions of the foregoing risks.</p><p>As with all mutual funds, investors may lose money by investing in the Conservative Portfolio.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
