HC Advisors Shares | The Value Equity Portfolio

<b>The Value Equity Portfolio</b>

<b>Investment Objective </b>

The investment objective of The Value Equity Portfolio is to provide total return consisting of capital appreciation and current income.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Value Equity Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The Value Equity Portfolio HC Advisors Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.13%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.07%
Total Annual Portfolio Operating Expenses	0.45%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Value Equity Portfolio HC Advisors Shares USD ($)
1 Year	$ 46
3 Years	144
5 Years	252
10 Years	$ 567

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 58.60% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

The Portfolio is a diversified investment company that is designed to implement a value-oriented investment approach. A “value investor” seeks to select securities that trade for less than the intrinsic value of the issuing company, as measured by fundamental investment considerations such as earnings, book value and dividend paying ability. Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio may invest up to 20% of the total assets of the actively managed portion of the Portfolio in income-producing securities other than common stock, such as bonds, including those that are convertible into common stock. These income-producing securities may be of any quality or maturity. The Portfolio will focus its investments in equity securities of large and mid-capitalization issuers. As of the date of this Prospectus, companies with a market capitalization of between $2.5 billion and $34.7 billion would likely be included in the “mid cap” range. Up to 20% of the total assets of the total Portfolio may also be invested in securities issued by non-U.S. companies. The Portfolio may invest in securities issued by other investment companies, including Exchange-Traded Funds (“ETFs”) that invest in equity securities. The Portfolio may also invest in option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one investment subadviser (“Specialist Manager”). The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk  – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Value Investing Risk – An investment in the Portfolio cannot assure moderation of investment risk. There is no guarantee that a value stock is, in fact, undervalued, or that the market will ever recognize its true value.

• Mid Cap Risk – Mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Performance Bar Chart and Table</b><br/><br/><b>Performance.</b>

HC Advisors Shares | The Institutional Value Equity Portfolio

<b>The Institutional Value Equity Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Institutional Value Equity Portfolio is to provide total return consisting of capital appreciation and current income.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Institutional Value Equity Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The Institutional Value Equity Portfolio HC Advisors Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.12%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.07%
Acquired Fund Fees and Expenses	0.02%
Total Annual Portfolio Operating Expenses	0.46%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Institutional Value Equity Portfolio HC Advisors Shares USD ($)
1 Year	$ 47
3 Years	148
5 Years	258
10 Years	$ 579

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 68.39% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

The Portfolio is a diversified investment company that is designed to implement a value-oriented investment approach. A “value investor” seeks to select securities that trade for less than the intrinsic value of the issuing company, as measured by fundamental investment considerations such as earnings, book value and dividend paying ability. Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio will focus its investments in equity securities of large and mid-capitalization issuers. As of the date of this Prospectus, companies with a market capitalization of between $2.5 billion and $34.7 billion would likely be included in the “mid cap” range. Up to 20% of the total assets of the actively managed portion of the Portfolio may be invested in income-producing securities other than common stock, such as bonds, including those that are convertible into common stock. These income-producing securities may be of any quality or maturity. Up to 20% of the total assets of the total Portfolio may also be invested in securities issued by non-U.S. companies. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities. Consistent with their respective investment styles, the Portfolio’s Specialist Managers may use option or futures contracts in order to pursue their investment objectives, gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Value Investing Risk – An investment in the Portfolio cannot assure moderation of investment risk. There is no guarantee that a value stock is, in fact, undervalued, or that the market will ever recognize its true value.

• Mid Cap Risk – Mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.     The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.     The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Advisors Shares | The Growth Equity Portfolio

<b>The Growth Equity Portfolio</b>

<b>Investment Objective </b>

The investment objective of The Growth Equity Portfolio is to provide capital appreciation,

with income as a secondary consideration.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/> (fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Growth Equity Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/> (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The Growth Equity Portfolio HC Advisors Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.18%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.07%
Total Annual Portfolio Operating Expenses	0.50%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Growth Equity Portfolio HC Advisors Shares USD ($)
1 Year	$ 51
3 Years	160
5 Years	280
10 Years	$ 628

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 39.77% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

The Portfolio is a diversified investment company that is designed to implement a growth-oriented investment approach. “Growth investing” means that securities acquired for the Portfolio can be expected to have above-average potential for growth in revenue and earnings. Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio may invest up to 20% of the total assets of the actively managed portion of the Portfolio in income-producing securities other than common stock, such as bonds, including those that are convertible into common stock. These income-producing securities may be of any quality or maturity. The Portfolio will focus its investments in equity securities of large and mid-capitalization issuers. As of the date of this Prospectus, companies with a market capitalization of between $2.5 billion and $34.7 billion would likely be included in the “mid cap” range. Up to 20% of the total assets of the total Portfolio may also be invested in securities issued by non-U.S. companies. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities. Although some of the equity securities in which the Portfolio will invest are expected to be dividend paying issues, income is a secondary consideration in the stock selection process. Accordingly, dividends paid by this Portfolio can generally be expected to be lower than those paid by The Value Equity Portfolio. Consistent with their respective investment styles, the Portfolio’s Specialist Managers may use option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Growth Investing Risk – An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty. Growth stocks typically have little or no dividend income to cushion the effect of adverse market conditions. In addition, growth stocks may be particularly volatile in the event of earnings disappointments or other financial difficulties experienced by the issuer.

• Mid Cap Risk – Mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy.

All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Growth Investing Risk – An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty. Growth stocks typically have little or no dividend income to cushion the effect of adverse market conditions. In addition, growth stocks may be particularly volatile in the event of earnings disappointments or other financial difficulties experienced by the issuer.

• Mid Cap Risk – Mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Advisors Shares | The Institutional Growth Equity Portfolio

<b>The Institutional Growth Equity Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Institutional Growth Equity Portfolio is to provide capital appreciation,

with income as a secondary consideration.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/> (fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Institutional Growth Equity Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/> (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The Institutional Growth Equity Portfolio HC Advisors Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.17%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.07%
Total Annual Portfolio Operating Expenses	0.49%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Institutional Growth Equity Portfolio HC Advisors Shares USD ($)
1 Year	$ 50
3 Years	157
5 Years	274
10 Years	$ 616

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 43.36% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

The Portfolio is a diversified investment company that is designed to implement a growth-oriented investment approach. “Growth investing” means that securities acquired for the Portfolio can be expected to have above-average potential for growth in revenue and earnings. Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio may invest up to 20% of the total assets of the actively managed portion of the Portfolio in income-producing securities other than common stock, such as bonds, including those that are convertible into common stock. These income-producing securities may be of any quality or maturity. The Portfolio will focus its investments in equity securities of large and mid-capitalization issuers. As of the date of this Prospectus, companies with a market capitalization of between $2.5 billion and $34.7 billion would likely be included in the “mid cap” range. Up to 20% of the total assets of the total Portfolio may also be invested in securities issued by non-U.S. companies. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities. Although some of the equity securities in which the Portfolio will invest are expected to be dividend paying issues, income is a secondary consideration in the stock selection process. Accordingly, dividends paid by this Portfolio can generally be expected to be lower than those paid by The Institutional Value Equity Portfolio. Consistent with their respective investment styles, the Portfolio’s Specialist Managers may use option or futures contracts in order to pursue their investment objectives, gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in foreign currencies. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Growth Investing Risk – An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty. Growth stocks typically have little or no dividend income to cushion the effect of adverse market conditions.

Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices.

The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

Portfolio Turnover [Text Block]

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 43.36% of the average value of its portfolio.

The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Portfolio is a diversified investment company that is designed to implement a growth-oriented investment approach. “Growth investing” means that securities acquired for the Portfolio can be expected to have above-average potential for growth in revenue and earnings. Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio may invest up to 20% of the total assets of the actively managed portion of the Portfolio in income-producing securities other than common stock, such as bonds, including those that are convertible into common stock. These income-producing securities may be of any quality or maturity. The Portfolio will focus its investments in equity securities of large and mid-capitalization issuers. As of the date of this Prospectus, companies with a market capitalization of between $2.5 billion and $34.7 billion would likely be included in the “mid cap” range. Up to 20% of the total assets of the total Portfolio may also be invested in securities issued by non-U.S. companies. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities. Although some of the equity securities in which the Portfolio will invest are expected to be dividend paying issues, income is a secondary consideration in the stock selection process. Accordingly, dividends paid by this Portfolio can generally be expected to be lower than those paid by The Institutional Value Equity Portfolio. Consistent with their respective investment styles, the Portfolio’s Specialist Managers may use option or futures contracts in order to pursue their investment objectives, gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in foreign currencies. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Growth Investing Risk – An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty. Growth stocks typically have little or no dividend income to cushion the effect of adverse market conditions. In addition, growth stocks may be particularly volatile in the event of earnings disappointments or other financial difficulties experienced by the issuer.

• Mid Cap Risk – Mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Advisors Shares | The Small Capitalization - Mid Capitalization Equity Portfolio

<b>The Small Capitalization – Mid Capitalization Equity Portfolio</b>

<b>Investment Objective </b>

The investment objective of The Small Capitalization-Mid Capitalization Equity Portfolio is to provide long-term capital appreciation.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same.

10 Years	$ 1,166

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 61.65% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities of small- capitalization and mid-capitalization issuers. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio, a diversified investment company, is designed to invest primarily in equity securities of U.S. issuers which have market capitalizations that are comparable to the capitalization of companies in the Russell 3000^® Index that are classified as “Small” or “Medium” at the time of purchase. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of “small cap” and/or “mid cap” issuers. The Portfolio will invest in both dividend paying securities and securities that do not pay dividends. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities. As of the date of this Prospectus, the market capitalization range of companies in the Russell 3000^® Index that were classified as “Small” or “Medium” was between approximately $159 million and $34.7 billion.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 61.65% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities of small- capitalization and mid-capitalization issuers. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio, a diversified investment company, is designed to invest primarily in equity securities of U.S. issuers which have market capitalizations that are comparable to the capitalization of companies in the Russell 3000^® Index that are classified as “Small” or “Medium” at the time of purchase. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of “small cap” and/or “mid cap” issuers. The Portfolio will invest in both dividend paying securities and securities that do not pay dividends. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities. As of the date of this Prospectus, the market capitalization range of companies in the Russell 3000^® Index that were classified as “Small” or “Medium” was between approximately $159 million and $34.7 billion.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

Risk [Heading]

rr_RiskHeading

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 95.15% of the average value of its portfolio.

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities of small-capitalization and mid-capitalization issuers. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio, a diversified investment company, is designed to invest primarily in equity securities of U.S. issuers which have market capitalizations that are comparable to the capitalization of companies in the Russell 3000^® Index that are classified as “Small” or “Medium” at the time of purchase. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of “small cap” and/or “mid cap” issuers. The Portfolio will invest in both dividend paying securities and securities that do not pay dividends. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities. As of July 31, 2018, the market capitalization range of companies in the Russell 3000^® Index that were classified as “Small” or “Medium” was between approximately $159 million and $34.7 billion.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Advisors Shares | The Real Estate Securities Portfolio

<b>The Real Estate Securities Portfolio</b>

<b>Investment Objective </b>

The investment objective of The Real Estate Securities Portfolio is to provide total return consisting of both capital appreciation and current income.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Real Estate Securities Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The Real Estate Securities Portfolio HC Advisors Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.67%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.08%
Acquired Fund Fees and Expenses	0.03%
Total Annual Portfolio Operating Expenses	1.03%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Real Estate Securities Portfolio HC Advisors Shares USD ($)
1 Year	$ 105
3 Years	328
5 Years	569
10 Years	$ 1,259

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 49.59% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in a portfolio of equity and debt securities issued by U.S. and non-U.S. real estate-related companies. Companies known as real estate investment trusts (REITs) and other real estate operating companies whose value is derived from ownership, development and management of underlying real estate properties are considered to be real estate-related companies. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio’s permissible investments include equity and equity-related securities of real estate-related companies, including common stock, preferred stock, convertible securities, warrants, options, depositary receipts and other similar equity equivalents. The Portfolio also may invest in fixed income securities, including debt securities, mortgage-backed securities and high yield debt (“junk bonds”). The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in securities issued by real estate-related companies. The Portfolio may also invest in companies which are located in emerging markets countries, as well as companies of any market capitalization.

Consistent with its investment style, the Portfolio’s Specialist Manager may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

The Portfolio is classified as a non-diversified fund, which means that the Portfolio is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as diversified.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

• Non-Diversification Risk – The Portfolio is classified as a non-diversified management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). This means that the Portfolio may invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as a diversified management investment company. Because the Portfolio may invest a relatively high percentage of its assets in a limited number of positions, the Portfolio’s performance may be more vulnerable to changes in the market value of a single position and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.
  
  Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Real Estate Investing Risk.

• Real Estate Markets and REIT Risk – Investments in the Portfolio will be closely linked to the performance of the real estate markets. Property values may fall due to increasing vacancies or declining rents resulting from unanticipated economic, legal, cultural or technological developments. REIT prices may also fall because of the failure of borrowers to pay their loans and/or poor management. The value of real estate (and real estate securities) may also be affected by increases in property taxes and changes in tax laws and interest rates. The value of securities of companies that service the real estate industry may also be affected by such risks. To the extent that the Portfolio invests in REITs and real estate partnerships, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired REITs and real estate partnerships. Investments in REITs and real estate partnerships (if any) may cause a greater portion of the Portfolio’s distributions to be taxable as ordinary income.

• Industry Concentration Risk – Because the Portfolio concentrates its investments in real estate securities, it may be subject to greater risks of loss as a result of economic, business or other developments than a fund representing a broader range of industries. The Portfolio may be subject to risks associated with direct ownership of real estate, such as changes in economic conditions, interest rates, availability of mortgage funds, property values, increases in property taxes and operating expenses, increased competition, environmental problems, changes in zoning laws and natural disasters.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the Morgan Stanley Capital International Europe, Australasia and Far East (“MSCI EAFE”) Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Extension Risk – Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

The bar chart shows returns on a before-tax basis and gives some indication of risk by showing changes in the Portfolio’s HC Advisors Shares yearly performance for each full calendar year since the Portfolio’s HC Advisors Shares inception on July 6, 2010 through December 31, 2012. Because the Portfolio’s HC Advisors Shares were redeemed in full on May 5, 2013 and no shares of the Portfolio’s HC Advisors Shares have since been sold, no performance information for 2013, 2014, 2015, 2016 and 2017 is shown in the bar chart (as the Portfolio was not active for a full calendar year in any of those years) or for the period from January 1, 2018 through September 30, 2018. The performance table shows the average annual total returns for the since inception period ended December 31, 2013 based on the actual one-year return and since inception annualized return calculated at April 30, 2013 and do not reflect the period of time when sales of shares and operations for the Portfolio’s HC Advisors Shares were active from May 1, 2013 through May 5, 2013. The table accompanying the bar chart compares the Portfolio’s performance over time on a before and after-tax basis to that of a broad based market index and includes index performance during the period when the Portfolio’s HC Advisors Shares were inactive. Accordingly, the Portfolio’s performance in the bar chart and table may not be comparable to the performance of other mutual funds. Of course, past performance, before and after taxes, does not indicate how the Portfolio will perform in the future.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance.

Strategy [Heading]

rr_StrategyHeading

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in a portfolio of equity and debt securities issued by U.S. and non-U.S. real estate-related companies. Companies known as real estate investment trusts (REITs) and other real estate operating companies whose value is derived from ownership, development and management of underlying real estate properties are considered to be real estate-related companies. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio’s permissible investments include equity and equity-related securities of real estate-related companies, including common stock, preferred stock, convertible securities, warrants, options, depositary receipts and other similar equity equivalents. The Portfolio also may invest in fixed income securities, including debt securities, mortgage-backed securities and high yield debt (“junk bonds”). The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in securities issued by real estate-related companies. The Portfolio may also invest in companies which are located in emerging markets countries, as well as companies of any market capitalization.

Consistent with its investment style, the Portfolio’s Specialist Manager may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

The Portfolio is classified as a non-diversified fund, which means that the Portfolio is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as diversified.

Risk [Heading]

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

• Non-Diversification Risk – The Portfolio is classified as a non-diversified management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). This means that the Portfolio may invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as a diversified management investment company. Because the Portfolio may invest a relatively high percentage of its assets in a limited number of positions, the Portfolio’s performance may be more vulnerable to changes in the market value of a single position and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.
  
  Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Real Estate Investing Risk.

• Real Estate Markets and REIT Risk – Investments in the Portfolio will be closely linked to the performance of the real estate markets. Property values may fall due to increasing vacancies or declining rents resulting from unanticipated economic, legal, cultural or technological developments. REIT prices may also fall because of the failure of borrowers to pay their loans and/or poor management. The value of real estate (and real estate securities) may also be affected by increases in property taxes and changes in tax laws and interest rates. The value of securities of companies that service the real estate industry may also be affected by such risks. To the extent that the Portfolio invests in REITs and real estate partnerships, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired REITs and real estate partnerships. Investments in REITs and real estate partnerships (if any) may cause a greater portion of the Portfolio’s distributions to be taxable as ordinary income.

• Industry Concentration Risk – Because the Portfolio concentrates its investments in real estate securities, it may be subject to greater risks of loss as a result of economic, business or other developments than a fund representing a broader range of industries. The Portfolio may be subject to risks associated with direct ownership of real estate, such as changes in economic conditions, interest rates, availability of mortgage funds, property values, increases in property taxes and operating expenses, increased competition, environmental problems, changes in zoning laws and natural disasters.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the Morgan Stanley Capital International Europe, Australasia and Far East (“MSCI EAFE”) Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Extension Risk – Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

Because the Portfolio’s HC Advisors Shares were redeemed in full on May 5, 2013 and no shares of the Portfolio’s HC Advisors Shares have since been sold, no performance information for 2013, 2014, 2015, 2016 and 2017 is shown in the bar chart (as the Portfolio was not active for a full calendar year in any of those years) or for the period from January 1, 2018 through September 30, 2018. The performance table shows the average annual total returns for the since inception period ended December 31, 2013 based on the actual one-year return and since inception annualized return calculated at April 30, 2013 and do not reflect the period of time when sales of shares and operations for the Portfolio’s HC Advisors Shares were active from May 1, 2013 through May 5, 2013. The table accompanying the bar chart compares the Portfolio’s performance over time on a before and after-tax basis to that of a broad based market index and includes index performance during the period when the Portfolio’s HC Advisors Shares were inactive. Accordingly, the Portfolio’s performance in the bar chart and table may not be comparable to the performance of other mutual funds.

5 Years	373
10 Years	$ 835

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 28.82% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily in a diversified portfolio of commodity-related investments including securities issued by companies in commodity-related industries, commodity-linked structured notes (derivative debt instruments with principal and/or coupon payments linked to the performance of commodity indices) and other similar derivative instruments, investment vehicles that invest in commodities and commodity-related instruments. Securities of companies in commodities-related industries may include common stocks, depositary receipts, preferred securities, rights to subscribe for or purchase any such securities, warrants, convertible securities and other equity and commodity-linked securities issued by such companies. For this purpose, commodities are assets that have tangible properties, such as oil, metal and agricultural products. Commodity-related industries include, but are not limited to: (i) those directly engaged in the production of commodities, such as minerals, metals, agricultural commodities, chemicals, pulp and paper, building materials, oil and gas, other energy or natural resources, and (ii) companies that provide services to commodity producers. The Portfolio considers a company to be in a commodity-related industry if, as determined by the relevant Specialist Manager, at least 50% of the company’s assets, revenues or net income are derived from, or related to, such activities. The Portfolio will invest more than 25% of its assets in securities issued by companies in commodity-related industries. The Portfolio may invest without limitation in foreign securities, including securities issued by companies in emerging markets. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in foreign currencies and to hedge against fluctuations in the relative value of the currencies in which securities held by the Portfolio are denominated. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in commodity-related investments. The Portfolio also intends to gain exposure to commodity markets by investing a portion of its assets in two wholly-owned subsidiaries organized under the laws of the Cayman Islands (the “Subsidiaries”). The Subsidiaries may invest without limitation in commodity-linked derivative instruments, such as swaps, futures and options. The Portfolio may invest in commodity swap, interest rate swap, variance swap and total return swap agreements and the Portfolio maintains liquid assets sufficient to cover the full notional value of any such swap positions. The Subsidiaries may also invest in debt securities, some of which are intended to serve as margin or collateral for the Subsidiaries’ derivatives positions, and other investment vehicles that invest in commodities and commodity-related instruments. The Subsidiaries are managed by the same Specialist Managers that advise the Portfolio.

The Portfolio may invest in equity and fixed income securities and may invest in companies of any market capitalization. Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that the Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Commodity-Related Investing Risks.    Investment in commodity-related securities involves the following risks:

• Commodity-Related Securities Risk – The securities of companies in commodity-related industries may underperform the stock market as a whole. The stock prices of such companies may also experience greater price volatility than other types of common stocks. Securities issued by companies in commodity-related industries are sensitive to changes in the supply and demand for, and thus the prices of, commodities. Additionally, the values of securities issued by commodity-related companies may be affected by factors affecting a particular industry or commodity.

• Commodity-Related Investment Risk – Exposure to the commodities markets may subject the Portfolio to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, interest rate changes or events affecting a particular commodity or industry, such as political instability or conflict, international economic and regulatory developments, embargoes and tariffs, and drought, floods and other weather-related events.

• Industry Concentration Risk – The Portfolio concentrates its investments in commodity-related industries. The focus of the Portfolio on a specific group of related industries my present more risks than if the Portfolio were more broadly diversified over numerous unrelated industries. A downturn in commodity-related industries would have a larger impact on the Portfolio than on an investment company that does not concentrate in such industries. At times, the performance of the Portfolio’s investments in commodity-related industries may lag the performance of other industries or the broader market as a whole.

• Subsidiary Risk – The commodity-related instruments held by the Subsidiaries are subject to the same risks that apply to similar investments if held directly by the Portfolio (see “Commodities Related Investment Risk” above). The Subsidiaries are not registered under the Investment Company Act and are not subject to all of the requirements and protections of that Act. However, the Portfolio wholly owns and controls the Subsidiaries, and the Board of Trustees has responsibility for overseeing the investment activities of the Portfolio, including its investment in the Subsidiaries. Changes in the laws of the United States and/or the Cayman Islands could adversely affect the Subsidiaries and/or the Portfolio.

• Commodity-Related Investment Tax Risk – The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Portfolio from certain commodity-linked derivatives was treated as non-qualifying income, the Portfolio might fail to qualify as a regulated investment company and/or be subject to federal income tax at the Portfolio level. Should the Internal Revenue Service (“IRS”) issue guidance, or Congress enact legislation, that adversely affects the tax treatment of commodity-linked notes or the Subsidiaries, it could, among other consequences, limit the Portfolio’s ability to pursue its investment strategy. For example, in September, 2016, the IRS released guidance stating that it would no longer issue rulings on any matter relating to the treatment of an entity as a Regulated Investment Company (“RIC”) if the matter would require a determination of whether a financial instrument or position is a security under the 1940 Act. To date, the Portfolio has not invested in any commodity-linked notes or other commodity-linked derivatives at the Portfolio level, although it retains the ability to make such investments in the future provided that such investments will not disqualify it for tax treatment as a RIC (or unless the Board determines that such disqualification is in the best interests of shareholders).

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Non-Investment Grade Securities Risk – Non-investment grade securities are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. Such securities may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Swaps Risks – The use of swaps is a highly specialized activity which involves investment techniques, risk analyses and tax planning different from those associated with ordinary portfolio securities transactions. Swap transactions can result in sizeable realized and unrealized capital gains and losses relative to the gains and losses from the Portfolio’s direct investments in securities and short sales. Transactions in swaps can involve greater risks than if the Portfolio had invested in securities directly since, in addition to general market risks, swaps may be leveraged and are also subject to liquidity risk, counterparty risk, credit risk and valuation risk. Regulators also may impose limits on an entity’s or group of entities’ positions in certain swaps.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Commodity-Related Investing Risks.    Investment in commodity-related securities involves the following risks:

• Commodity-Related Securities Risk – The securities of companies in commodity-related industries may underperform the stock market as a whole. The stock prices of such companies may also experience greater price volatility than other types of common stocks. Securities issued by companies in commodity-related industries are sensitive to changes in the supply and demand for, and thus the prices of, commodities. Additionally, the values of securities issued by commodity-related companies may be affected by factors affecting a particular industry or commodity.

• Commodity-Related Investment Risk – Exposure to the commodities markets may subject the Portfolio to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, interest rate changes or events affecting a particular commodity or industry, such as political instability or conflict, international economic and regulatory developments, embargoes and tariffs, and drought, floods and other weather-related events.

• Industry Concentration Risk – The Portfolio concentrates its investments in commodity-related industries. The focus of the Portfolio on a specific group of related industries my present more risks than if the Portfolio were more broadly diversified over numerous unrelated industries. A downturn in commodity-related industries would have a larger impact on the Portfolio than on an investment company that does not concentrate in such industries. At times, the performance of the Portfolio’s investments in commodity-related industries may lag the performance of other industries or the broader market as a whole.

• Subsidiary Risk – The commodity-related instruments held by the Subsidiaries are subject to the same risks that apply to similar investments if held directly by the Portfolio (see “Commodities Related Investment Risk” above). The Subsidiaries are not registered under the Investment Company Act and are not subject to all of the requirements and protections of that Act. However, the Portfolio wholly owns and controls the Subsidiaries, and the Board of Trustees has responsibility for overseeing the investment activities of the Portfolio, including its investment in the Subsidiaries. Changes in the laws of the United States and/or the Cayman Islands could adversely affect the Subsidiaries and/or the Portfolio.

• Commodity-Related Investment Tax Risk – The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Portfolio from certain commodity-linked derivatives was treated as non-qualifying income, the Portfolio might fail to qualify as a regulated investment company and/or be subject to federal income tax at the Portfolio level. Should the Internal Revenue Service (“IRS”) issue guidance, or Congress enact legislation, that adversely affects the tax treatment of commodity-linked notes or the Subsidiaries, it could, among other consequences, limit the Portfolio’s ability to pursue its investment strategy. For example, in September, 2016, the IRS released guidance stating that it would no longer issue rulings on any matter relating to the treatment of an entity as a Regulated Investment Company (“RIC”) if the matter would require a determination of whether a financial instrument or position is a security under the 1940 Act. To date, the Portfolio has not invested in any commodity-linked notes or other commodity-linked derivatives at the Portfolio level, although it retains the ability to make such investments in the future provided that such investments will not disqualify it for tax treatment as a RIC (or unless the Board determines that such disqualification is in the best interests of shareholders).

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Non-Investment Grade Securities Risk – Non-investment grade securities are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. Such securities may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Swaps Risks – The use of swaps is a highly specialized activity which involves investment techniques, risk analyses and tax planning different from those associated with ordinary portfolio securities transactions. Swap transactions can result in sizeable realized and unrealized capital gains and losses relative to the gains and losses from the Portfolio’s direct investments in securities and short sales. Transactions in swaps can involve greater risks than if the Portfolio had invested in securities directly since, in addition to general market risks, swaps may be leveraged and are also subject to liquidity risk, counterparty risk, credit risk and valuation risk. Regulators also may impose limits on an entity’s or group of entities’ positions in certain swaps.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Advisors Shares | The ESG Growth Portfolio

<b>The ESG Growth Portfolio </b>

<b>Investment Objective </b>

The ESG Growth Portfolio seeks to maximize total return while emphasizing environmental, social and governance (“ESG”) focused investments.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The ESG Growth Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The ESG Growth Portfolio HC Advisors Shares
Management Fees	0.22%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.12%
Total Annual Portfolio Operating Expenses	0.59%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The ESG Growth Portfolio HC Advisors Shares USD ($)
1 Year	$ 60
3 Years	189
5 Years	329
10 Years	$ 738

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in Total Annual Portfolio Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 15.54% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its total return objective, which includes a combination of capital appreciation and income, by investing primarily in equity securities. The Portfolio is permitted to invest in any equity security, which includes securities issued by other investment companies, including exchange traded funds (“ETFs”) and securities issued by one or more of the other portfolios of HC Capital Trust. The Portfolio may invest in companies of any market capitalization.

Further, under the supervision of the Adviser, environmental, social and governance criteria (“ESG Factors) will be integrated into the Portfolio’s security selection process through the application of non-financial criteria (“ESG Screens”). The ESG Screens used by the Portfolio are determined with the use of third party data and ESG rating agencies which take into account a company’s performance around environmental, social and corporate governance practices. These may include (but are not limited to) such themes as climate change, resource efficiency, labor standards, product and service safety, community engagement, board policies, and corporate structure. The Portfolio seeks to avoid investment in securities issued by companies that have not demonstrated a commitment to ESG issues. Additionally, the Portfolio’s ESG Screens may not necessarily be applied to investments in derivatives, certain fixed income investments and other investments where in the Advisor’s opinion ESG Factors are not applicable or it is not possible to implement them. The ESG Screens will be applied by the Specialist Managers that manage the Portfolio under the direction of the Adviser. The ESG Screens used by each Specialist Manager may differ from one another.

The Portfolio may also invest without limitation in fixed income securities of all types and without regard to duration or investment ratings. Fixed income investments may include corporate debt, including high yield or “junk bonds,” structured notes, asset backed securities and similar synthetic securities, U.S. treasuries and short-term money market instruments or other cash equivalents.

The Portfolio is permitted to invest in securities issued by companies domiciled anywhere in the world and denominated in any currency, without limitation. The Portfolio may also invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk.    The Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the broad range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Investment in Other Investment Companies Risk – To the extent that the Portfolio acquires securities issued by other investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies. Securities issued by other investment companies, including ETFs, are also equity securities and, as such, are subject to Market Risk and Management Risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively do so.

• ESG Investing Risk.    The Portfolio seeks to avoid investment in securities issued by companies that have not demonstrated a commitment to ESG issues. The Portfolio’s use of ESG Factors in making investment decisions may include the following risks.

• Risk of Excluding Performing Companies – The Portfolio’s ESG policy may cause it to perform differently than funds that do not have an ESG focus. The Portfolio’s ESG focus may result in the Portfolio foregoing opportunities to buy or sell certain securities when it might otherwise be advantageous to do so.

• Information Risk – The ESG Screens used by the Portfolio are determined in part through the use of third party data and ESG rating agencies. Information relating to the ESG performance of the companies in which the Portfolio may invest may not be complete, accurate or readily available. This fact may negatively impact the effectiveness of the ESG Screens.

• Foreign Investment Risk. –  Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities. Additionally, risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time. The Portfolio generally considers “emerging markets” countries to be those included in the MSCI Emerging Markets Index.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income.

• Extension Risk – Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Asset-Backed/Mortgage-Backed Securities Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Risks Associated with Investments in Futures.    The Portfolio is permitted to invest in futures. Investment in futures depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Futures involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks.
  
  The value of futures may rise or fall more rapidly than other investments and there is a risk that the Portfolio may lose more than the original amount invested in futures. Futures also involve the risk that other parties to the futures contract may fail to meet their obligations, which could cause losses to the Portfolio. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances. Compared to other types of investments, futures may be harder to value and may also be less tax efficient. To the extent that the Portfolio uses futures to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the futures instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of futures may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Thinly traded Securities.    The Portfolio may invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues. Investment in these securities involve the following risks:

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Valuation Risk – When market quotations are not readily available or are deemed to be unreliable, the Portfolio values its investments at fair value as determined in good faith pursuant to policies and procedures approved by the Board of Trustees. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets, or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in Total Annual Portfolio Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 15.54% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its total return objective, which includes a combination of capital appreciation and income, by investing primarily in equity securities. The Portfolio is permitted to invest in any equity security, which includes securities issued by other investment companies, including exchange traded funds (“ETFs”) and securities issued by one or more of the other portfolios of HC Capital Trust. The Portfolio may invest in companies of any market capitalization.

Further, under the supervision of the Adviser, environmental, social and governance criteria (“ESG Factors) will be integrated into the Portfolio’s security selection process through the application of non-financial criteria (“ESG Screens”). The ESG Screens used by the Portfolio are determined with the use of third party data and ESG rating agencies which take into account a company’s performance around environmental, social and corporate governance practices. These may include (but are not limited to) such themes as climate change, resource efficiency, labor standards, product and service safety, community engagement, board policies, and corporate structure. The Portfolio seeks to avoid investment in securities issued by companies that have not demonstrated a commitment to ESG issues. Additionally, the Portfolio’s ESG Screens may not necessarily be applied to investments in derivatives, certain fixed income investments and other investments where in the Advisor’s opinion ESG Factors are not applicable or it is not possible to implement them. The ESG Screens will be applied by the Specialist Managers that manage the Portfolio under the direction of the Adviser. The ESG Screens used by each Specialist Manager may differ from one another.

The Portfolio may also invest without limitation in fixed income securities of all types and without regard to duration or investment ratings. Fixed income investments may include corporate debt, including high yield or “junk bonds,” structured notes, asset backed securities and similar synthetic securities, U.S. treasuries and short-term money market instruments or other cash equivalents.

The Portfolio is permitted to invest in securities issued by companies domiciled anywhere in the world and denominated in any currency, without limitation. The Portfolio may also invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues.

Risk [Heading]

rr_RiskHeading

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk.    The Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the broad range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Investment in Other Investment Companies Risk – To the extent that the Portfolio acquires securities issued by other investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies. Securities issued by other investment companies, including ETFs, are also equity securities and, as such, are subject to Market Risk and Management Risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively do so.

• ESG Investing Risk.    The Portfolio seeks to avoid investment in securities issued by companies that have not demonstrated a commitment to ESG issues. The Portfolio’s use of ESG Factors in making investment decisions may include the following risks.

• Risk of Excluding Performing Companies – The Portfolio’s ESG policy may cause it to perform differently than funds that do not have an ESG focus. The Portfolio’s ESG focus may result in the Portfolio foregoing opportunities to buy or sell certain securities when it might otherwise be advantageous to do so.

• Information Risk – The ESG Screens used by the Portfolio are determined in part through the use of third party data and ESG rating agencies. Information relating to the ESG performance of the companies in which the Portfolio may invest may not be complete, accurate or readily available. This fact may negatively impact the effectiveness of the ESG Screens.

• Foreign Investment Risk. –  Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities. Additionally, risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time. The Portfolio generally considers “emerging markets” countries to be those included in the MSCI Emerging Markets Index.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income.

• Extension Risk – Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Asset-Backed/Mortgage-Backed Securities Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Risks Associated with Investments in Futures.    The Portfolio is permitted to invest in futures. Investment in futures depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Futures involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks.
  
  The value of futures may rise or fall more rapidly than other investments and there is a risk that the Portfolio may lose more than the original amount invested in futures. Futures also involve the risk that other parties to the futures contract may fail to meet their obligations, which could cause losses to the Portfolio. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances. Compared to other types of investments, futures may be harder to value and may also be less tax efficient. To the extent that the Portfolio uses futures to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the futures instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of futures may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Thinly traded Securities.    The Portfolio may invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues. Investment in these securities involve the following risks:

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Valuation Risk – When market quotations are not readily available or are deemed to be unreliable, the Portfolio values its investments at fair value as determined in good faith pursuant to policies and procedures approved by the Board of Trustees. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets, or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

Expense Example	HC Advisors Shares The Catholic SRI Growth Portfolio HC Advisors Shares USD ($)
1 Year	$ 68
3 Years	214
5 Years	373
10 Years	$ 835

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in Total Annual Portfolio Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 17.01% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective, which includes a combination of capital appreciation and income, by investing primarily in equity securities while retaining the flexibility to invest in fixed income securities. In addition to equity and fixed income securities, the Portfolio may invest in other instruments, including, but not limited to, derivatives. The Portfolio is permitted to invest in any equity security, which includes securities issued by other investment companies, including exchange traded funds (“ETFs”) and securities issued by one or more of the other portfolios of HC Capital Trust. The Portfolio may invest in companies of any market capitalization.

Further, under the supervision of the Adviser, the Portfolio integrates a range of social and moral concerns into its security selection process. These issues may include protecting human life; promoting human dignity; reducing arms production; pursuing economic justice; protecting the environment, and encouraging corporate responsibility. This will be accomplished with reference to the principles contained in the United States Conference of Catholic Bishops’ (“USCCB”) Socially Responsible Investing Guidelines (“Social Guidelines”). Potential investments for the Portfolio are selected for financial soundness and evaluated according to the Portfolio’s social criteria.

The Portfolio may also invest without limitation in fixed income securities of all types and without regard to duration or investment ratings. Fixed income investments may include corporate debt, including high yield or “junk bonds,” structured notes, asset backed securities and similar synthetic securities, U.S. treasuries and short-term money market instruments or other cash equivalents.

The Portfolio is permitted to invest in securities issued by companies domiciled anywhere in the world and denominated in any currency, without limitation. The Portfolio may also invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues. Additionally, in seeking to achieve its objective, the Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards.

The Portfolio is classified as a non-diversified fund, which means that the Portfolio is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as diversified.

The Portfolio is not authorized or sponsored by the Roman Catholic Church or the USCCB.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Non-diversification Risk.    A non-diversified fund, such as the Portfolio, is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if it were classified as diversified. As a non-diversified fund, the Portfolio’s performance may be more vulnerable to changes in the market value of a single position and risks associated with a single economic, political or regulatory occurrence than a diversified fund.

• Multi-Manager Risk.    The Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the broad range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Investment in Other Investment Companies Risk – To the extent that the Portfolio acquires securities issued by other investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies. Securities issued by other investment companies, including ETFs, are also equity securities and, as such, are subject to Market Risk and Management Risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively do so.

• Socially Responsible Investing Risk.    The Portfolio considers the Social Guidelines in its investment process and may choose not to purchase, or may sell, otherwise profitable investments in companies which have been identified as being in conflict with the Social Guidelines. This means that the Portfolio may underperform other similar funds that do not consider the Social Guidelines when making investment decisions.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities. Additionally, risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time. The Portfolio generally considers “emerging markets” countries to be those included in the MSCI Emerging Markets Index

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities.

• Extension Risk –  Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Credit Risk –  An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• High Yield Bond Risk –  High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Asset-Backed/Mortgage-Backed Securities Risk –  The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Risks Associated with Investments in Futures.    The Portfolio is permitted to invest in futures. Investment in futures depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Futures involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks.
  
  The value of futures may rise or fall more rapidly than other investments and there is a risk that the Portfolio may lose more than the original amount invested in futures. Futures also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances. Compared to other types of investments, futures may be harder to value and may also be less tax efficient. To the extent that the Portfolio uses futures to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the futures instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of futures may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Thinly traded Securities.    The Portfolio may invest in securities, including privately placed and structured securities and derivatives, for which there may be limited markets/thinly traded issues. Investment in these securities involve the following risks:

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Valuation Risk – When market quotations are not readily available or are deemed to be unreliable, the Portfolio values its investments at fair value as determined in good faith pursuant to policies and procedures approved by the Board of Trustees. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets, or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

Strategy [Heading]

rr_StrategyHeading

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective, which includes a combination of capital appreciation and income, by investing primarily in equity securities while retaining the flexibility to invest in fixed income securities. In addition to equity and fixed income securities, the Portfolio may invest in other instruments, including, but not limited to, derivatives. The Portfolio is permitted to invest in any equity security, which includes securities issued by other investment companies, including exchange traded funds (“ETFs”) and securities issued by one or more of the other portfolios of HC Capital Trust. The Portfolio may invest in companies of any market capitalization.

Further, under the supervision of the Adviser, the Portfolio integrates a range of social and moral concerns into its security selection process. These issues may include protecting human life; promoting human dignity; reducing arms production; pursuing economic justice; protecting the environment, and encouraging corporate responsibility. This will be accomplished with reference to the principles contained in the United States Conference of Catholic Bishops’ (“USCCB”) Socially Responsible Investing Guidelines (“Social Guidelines”). Potential investments for the Portfolio are selected for financial soundness and evaluated according to the Portfolio’s social criteria.

The Portfolio may also invest without limitation in fixed income securities of all types and without regard to duration or investment ratings. Fixed income investments may include corporate debt, including high yield or “junk bonds,” structured notes, asset backed securities and similar synthetic securities, U.S. treasuries and short-term money market instruments or other cash equivalents.

The Portfolio is permitted to invest in securities issued by companies domiciled anywhere in the world and denominated in any currency, without limitation. The Portfolio may also invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues. Additionally, in seeking to achieve its objective, the Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards.

The Portfolio is classified as a non-diversified fund, which means that the Portfolio is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as diversified.

The Portfolio is not authorized or sponsored by the Roman Catholic Church or the USCCB.

Risk [Heading]

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Non-diversification Risk.    A non-diversified fund, such as the Portfolio, is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if it were classified as diversified. As a non-diversified fund, the Portfolio’s performance may be more vulnerable to changes in the market value of a single position and risks associated with a single economic, political or regulatory occurrence than a diversified fund.

• Multi-Manager Risk.    The Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the broad range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Investment in Other Investment Companies Risk – To the extent that the Portfolio acquires securities issued by other investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies. Securities issued by other investment companies, including ETFs, are also equity securities and, as such, are subject to Market Risk and Management Risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively do so.

• Socially Responsible Investing Risk.    The Portfolio considers the Social Guidelines in its investment process and may choose not to purchase, or may sell, otherwise profitable investments in companies which have been identified as being in conflict with the Social Guidelines. This means that the Portfolio may underperform other similar funds that do not consider the Social Guidelines when making investment decisions.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities. Additionally, risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time. The Portfolio generally considers “emerging markets” countries to be those included in the MSCI Emerging Markets Index

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income.

• Extension Risk –  Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Credit Risk –  An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• High Yield Bond Risk –  High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Asset-Backed/Mortgage-Backed Securities Risk –  The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Risks Associated with Investments in Futures.    The Portfolio is permitted to invest in futures. Investment in futures depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Futures involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks.
  
  The value of futures may rise or fall more rapidly than other investments and there is a risk that the Portfolio may lose more than the original amount invested in futures. Futures also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances. Compared to other types of investments, futures may be harder to value and may also be less tax efficient. To the extent that the Portfolio uses futures to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the futures instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of futures may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Thinly traded Securities.    The Portfolio may invest in securities, including privately placed and structured securities and derivatives, for which there may be limited markets/thinly traded issues. Investment in these securities involve the following risks:

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Valuation Risk – When market quotations are not readily available or are deemed to be unreliable, the Portfolio values its investments at fair value as determined in good faith pursuant to policies and procedures approved by the Board of Trustees. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets, or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

HC Advisors Shares | The International Equity Portfolio

<b>The International Equity Portfolio </b>

<b>Investment Objective </b>

The investment objective of The International Equity Portfolio is to maximize total return.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The International Equity Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The International Equity Portfolio HC Advisors Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.34%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.09%
Total Annual Portfolio Operating Expenses	0.68%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The International Equity Portfolio HC Advisors Shares USD ($)
1 Year	$ 69
3 Years	218
5 Years	379
10 Years	$ 847

<b>Portfolio Turnover</b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 29.94% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Under normal circumstances, the Portfolio will provide exposure to investments that are economically tied to at least three different countries, including the U.S., and at least 40% of the Portfolio’s net assets will provide exposure to investments that are economically tied to non-U.S. countries. Although the Portfolio, a diversified investment company, may invest anywhere in the world, the Portfolio is expected to invest primarily in the equity markets included in the MSCI EAFE Index. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of issuers located in non-U.S. countries. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in foreign currencies and to hedge against fluctuations in the relative value of the currencies in which securities held by the Portfolio are denominated. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Under normal circumstances, the Portfolio will provide exposure to investments that are economically tied to at least three different countries, including the U.S., and at least 40% of the Portfolio’s net assets will provide exposure to investments that are economically tied to non-U.S. countries. Although the Portfolio, a diversified investment company, may invest anywhere in the world, the Portfolio is expected to invest primarily in the equity markets included in the MSCI EAFE Index. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of issuers located in non-U.S. countries. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in foreign currencies and to hedge against fluctuations in the relative value of the currencies in which securities held by the Portfolio are denominated. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

HC Advisors Shares | The Institutional International Equity Portfolio

<b>The Institutional International Equity Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Institutional International Equity Portfolio is to maximize total return.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Institutional International Equity Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Institutional International Equity Portfolio HC Advisors Shares USD ($)
1 Year	$ 74
3 Years	230
5 Years	401
10 Years	$ 894

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 40.38% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Under normal circumstances, the Portfolio will provide exposure to investments that are economically tied to at least three different countries, including the U.S., and at least 40% of the Portfolio’s net assets will provide exposure to investments that are economically tied to non-U.S. countries. Although the Portfolio, a diversified investment company, may invest anywhere in the world, the Portfolio is expected to invest primarily in the equity markets included in the MSCI EAFE Index.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Under normal circumstances, the Portfolio will provide exposure to investments that are economically tied to at least three different countries, including the U.S., and at least 40% of the Portfolio’s net assets will provide exposure to investments that are economically tied to non-U.S. countries. Although the Portfolio, a diversified investment company, may invest anywhere in the world, the Portfolio is expected to invest primarily in the equity markets included in the MSCI EAFE Index. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of issuers located in non-U.S. countries. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in a foreign currency and to hedge against fluctuations in the relative value of the currencies in which securities held by the Portfolio are denominated. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

Investing in the Portfolio involves risks common to any investment in securities.

HC Advisors Shares | The Emerging Markets Portfolio

<b>The Emerging Markets Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Emerging Markets Portfolio is to provide maximum total return, primarily through capital appreciation.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Emerging Markets Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The Emerging Markets Portfolio HC Advisors Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.49%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.17%
Acquired Fund Fees and Expenses	0.02%
Total Annual Portfolio Operating Expenses	0.93%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Emerging Markets Portfolio HC Advisors Shares USD ($)
1 Year	$ 95
3 Years	296
5 Years	515
10 Years	$ 1,143

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 54.90% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in securities of issuers domiciled or, in the view of the Specialist Manager, deemed to be doing material amounts of business in countries determined by the Specialist Manager to have a developing or emerging economy or securities market. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Typically 80% of the Portfolio’s net assets will be invested in equity securities, equity swaps, structured equity notes, equity linked notes and depositary receipts of issuers domiciled or, in the view of the Specialist Manager, deemed to be doing material amounts of business in emerging market countries. The Portfolio, a diversified investment company, invests primarily in the Morgan Stanley Capital International^® Emerging Markets Index (“MSCI EM Index”) countries. As the MSCI EM Index introduces new emerging market countries, the Portfolio may include those countries among the countries in which it may invest. In determining securities in which to invest, the Portfolio’s management team will evaluate the countries’ economic and political climates with prospects for sustained macro and micro economic growth. The Portfolio’s management team will take into account traditional securities valuation methods, including (but not limited to) an analysis of price in relation to assets, earnings, cash flows, projected earnings growth, inflation and interest rates. Liquidity and transaction costs will also be considered. The Portfolio may also invest in companies of any market capitalization. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in securities issued by companies domiciled or deemed to be doing material amounts of business in countries that have a developing or emerging economy or securities market. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• China Risk.    In addition to the risks listed above under “Emerging Market Securities,” investing in China presents additional risks including confiscatory taxation, nationalization, exchange control regulations (including currency blockage) and differing legal standards. The Chinese government could, at any time, alter or discontinue economic reform programs implemented since 1978. Chinese authorities may intervene in the China securities market and halt or suspend trading of securities for short or even longer periods of time. Recently, the China securities market has experienced considerable volatility and been subject to relatively frequent and extensive trading halts and suspensions. These trading halts and suspensions have, among other things, contributed to uncertainty in the markets and reduced the liquidity of the securities subject to such trading halts and suspensions, which could include securities held by a Portfolio.

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

Strategy [Heading]

rr_StrategyHeading

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in securities of issuers domiciled or, in the view of the Specialist Manager, deemed to be doing material amounts of business in countries determined by the Specialist Manager to have a developing or emerging economy or securities market. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Typically 80% of the Portfolio’s net assets will be invested in equity securities, equity swaps, structured equity notes, equity linked notes and depositary receipts of issuers domiciled or, in the view of the Specialist Manager, deemed to be doing material amounts of business in emerging market countries. The Portfolio, a diversified investment company, invests primarily in the Morgan Stanley Capital International^® Emerging Markets Index (“MSCI EM Index”) countries. As the MSCI EM Index introduces new emerging market countries, the Portfolio may include those countries among the countries in which it may invest. In determining securities in which to invest, the Portfolio’s management team will evaluate the countries’ economic and political climates with prospects for sustained macro and micro economic growth. The Portfolio’s management team will take into account traditional securities valuation methods, including (but not limited to) an analysis of price in relation to assets, earnings, cash flows, projected earnings growth, inflation and interest rates. Liquidity and transaction costs will also be considered. The Portfolio may also invest in companies of any market capitalization. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in securities issued by companies domiciled or deemed to be doing material amounts of business in countries that have a developing or emerging economy or securities market. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 43.79% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in fixed income securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio, under normal circumstances, invests predominantly in fixed income securities that, at the time of purchase, are rated in one of four highest rating categories assigned by one of the major independent rating agencies (“Baa” or higher by Moodys, “BBB” or higher by Standard & Poor’s) or are, in the view of the Specialist Manager, deemed to be of comparable quality. Securities in the fourth highest rating category may have speculative characteristics. From time to time, a substantial portion of the Portfolio, a diversified investment company, may be invested in any of the following: (1) investment grade mortgage-backed or asset-backed securities; (2) securities issued or fully guaranteed by the U.S. Government, Federal Agencies, or sponsored agencies; (3) investment grade fixed income securities issued by U.S. corporations; or (4) municipal bonds (i.e., debt securities issued by municipalities and related entities). Under normal conditions, the Portfolio may invest up to 20% of its assets in high yield securities (“junk bonds”) as well as cash or money market instruments in order to maintain liquidity, or in the event that the Specialist Manager determines that securities meeting the Portfolio’s investment objective and policies are not otherwise readily available for purchase. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in fixed income securities. Consistent with its investment policies, the Portfolio may purchase and sell securities without regard to the effect on portfolio turnover. Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Aggregate Bond Index, which range, as of June 30, 2018, was between 1 and 29 years. The weighted average maturity of the Bloomberg Barclays U.S. Aggregate Bond Index as of June 30, 2018 was 12.9 years. The Portfolio may engage in transactions involving instruments such as option or futures contracts, both in order to hedge against fluctuations in the market value of the securities in which the Portfolio invests and to achieve market exposure pending investment and, in the case of asset-backed and similar securities, for investment purposes.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• High Turnover Risk – High portfolio turnover will cause the Portfolio to incur additional transaction costs; higher transaction costs will reduce total return. High portfolio turnover also is likely to generate short-term capital gains, which, once distributed, is taxed to the shareholder as ordinary income and does not retain its character as short-term capital gain in the hands of a shareholder.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Portfolio dividends derived from certain “private activity” municipal securities generally will constitute an item of tax preference includable in alternative minimum taxable income for both corporate and non-corporate taxpayers.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Advisors Shares | The Fixed Income Opportunity Portfolio

<b>The Fixed Income Opportunity Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Fixed Income Opportunity Portfolio is to achieve above-average total return by investing in high yield securities commonly referred to as “junk bonds.”

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Fixed Income Opportunity Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The Fixed Income Opportunity Portfolio HC Advisors Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.38%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.08%
Acquired Fund Fees and Expenses	0.04%
Total Annual Portfolio Operating Expenses	0.75%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes the reinvestment of all dividends and distributions in shares of the Portfolio and that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Fixed Income Opportunity Portfolio HC Advisors Shares USD ($)
1 Year	$ 77
3 Years	240
5 Years	417
10 Years	$ 930

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 37.57% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of net assets) in fixed income securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. A principal investment strategy of the Portfolio is to invest in high yield securities including “junk bonds.” Under normal circumstances, at least 50% of the Portfolio’s total assets will be invested in junk bonds. These securities are fixed income securities that are rated below the fourth highest category assigned by one of the major independent rating agencies or are, in the view of the Specialist Manager, deemed to be of comparable quality. Such securities may include: corporate bonds, collateralized loan obligations (CLOs), collateralized bond obligations (CBOs) and collateralized debt obligations (CDOs) (CDO investments are expected to be limited to less than 15% of the Portfolio), agency and non-agency mortgage-backed securities, collateralized mortgage obligations, commercial mortgage-backed securities and asset-backed securities, REITs, foreign fixed income securities, including emerging market debt, convertible bonds, preferred stocks, treasury inflation bonds, loan participations, swaps and fixed and floating rate loans. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in fixed income securities.

The Portfolio may invest in U.S. government securities, including but not limited to treasuries, agencies and commercial paper. The Portfolio may also hold a portion of its assets in cash or money market instruments in order to maintain liquidity or in the event that the Specialist Manager determines that securities meeting the Portfolio’s investment objective and policies are not otherwise readily available for purchase.

Consistent with its investment policies, the Portfolio may purchase and sell high yield securities. Purchases and sales of securities may be effected without regard to the effect on portfolio turnover. Securities purchased for the Portfolio will have varying maturities, but, under normal circumstances, the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. High Yield Ba/B 2% Issuer Capped Index, which range, as of June 30, 2018, was between 1 and 13 years. The Portfolio may engage in transactions involving instruments such as option or futures contracts, both in order to hedge against fluctuations in the market value of the securities in which the Portfolio invests and to achieve market exposure pending investment.

The performance benchmark for this Portfolio is the Bloomberg Barclays U.S. High Yield Ba/B 2% Issuer Capped Index, an unmanaged index of high yield securities that is widely recognized as an indicator of the performance of such securities. The Specialist Managers actively manage the interest rate risk of the Portfolio relative to this benchmark.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Floating Rate Loans Risk – The risks associated with floating rate loans are similar to the risks of below investment grade securities. Changes in economic conditions are likely to cause issuers of these securities to be unable to meet their obligations. In addition, the value of the collateral securing the loan may decline, causing a loan to be substantially unsecured. The sale and purchase of a bank loan are subject to the requirements of the underlying credit agreement governing such bank loan. These requirements may limit the eligible pool of potential bank loan holders by placing conditions or restrictions on sales and purchases of bank loans. Further, bank loans are not traded on an exchange and purchasers and sellers of bank loans rely on market makers, usually the administrative agent for a particular bank loan, to trade bank loans. These factors, in addition to overall market volatility, may negatively impact the liquidity of loans. Difficulty in selling a floating rate loan may result in a loss. Borrowers may pay back principal before the scheduled due date when interest rates decline, which may require the Portfolio to replace a particular loan with a lower-yielding security. There may be less extensive public information available with respect to loans than for rated, registered or exchange listed securities. The Portfolio may assume the credit risk of the primary lender in addition to the borrower, and investments in loan assignments may involve the risks of being a lender.

• Loan Participation Risk – Loan participations typically will result in a Portfolio having a contractual relationship only with the lender, not with the borrower. In connection with purchasing loan participations, a Portfolio generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and a Portfolio may not benefit directly from any collateral supporting the loan in which it has purchased the participation. As a result, a Portfolio will assume the credit risk of both the borrower and the lender that is selling the participation. A Portfolio may have difficulty disposing of loan participations as the market for such instruments is not highly liquid.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments, including option and futures contracts, may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• REIT Risk – REIT prices may fall because of the failure of borrowers to pay their loans and/or poor management. The value of REITs may also be affected by increases in property taxes and changes in tax laws and interest rates.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Floating Rate Loans Risk – The risks associated with floating rate loans are similar to the risks of below investment grade securities. Changes in economic conditions are likely to cause issuers of these securities to be unable to meet their obligations. In addition, the value of the collateral securing the loan may decline, causing a loan to be substantially unsecured. The sale and purchase of a bank loan are subject to the requirements of the underlying credit agreement governing such bank loan. These requirements may limit the eligible pool of potential bank loan holders by placing conditions or restrictions on sales and purchases of bank loans. Further, bank loans are not traded on an exchange and purchasers and sellers of bank loans rely on market makers, usually the administrative agent for a particular bank loan, to trade bank loans. These factors, in addition to overall market volatility, may negatively impact the liquidity of loans. Difficulty in selling a floating rate loan may result in a loss. Borrowers may pay back principal before the scheduled due date when interest rates decline, which may require the Portfolio to replace a particular loan with a lower-yielding security. There may be less extensive public information available with respect to loans than for rated, registered or exchange listed securities. The Portfolio may assume the credit risk of the primary lender in addition to the borrower, and investments in loan assignments may involve the risks of being a lender.

• Loan Participation Risk – Loan participations typically will result in a Portfolio having a contractual relationship only with the lender, not with the borrower. In connection with purchasing loan participations, a Portfolio generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and a Portfolio may not benefit directly from any collateral supporting the loan in which it has purchased the participation. As a result, a Portfolio will assume the credit risk of both the borrower and the lender that is selling the participation. A Portfolio may have difficulty disposing of loan participations as the market for such instruments is not highly liquid.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments, including option and futures contracts, may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• REIT Risk – REIT prices may fall because of the failure of borrowers to pay their loans and/or poor management. The value of REITs may also be affected by increases in property taxes and changes in tax laws and interest rates.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Advisors Shares | The U.S. Government Fixed Income Securities Portfolio

<b>The U.S. Government Fixed Income Securities Portfolio </b>

<b>Investment Objective </b>

The investment objective of The U.S. Government Fixed Income Securities Portfolio is to provide a moderate and sustainable level of current income, consistent with the preservation of capital by investing in a diversified portfolio of primarily U.S. Treasury and government related fixed income securities.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The U.S. Government Fixed Income Securities Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The U.S. Government Fixed Income Securities Portfolio HC Advisors Shares
Management Fees	0.11%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.08%
Total Annual Portfolio Operating Expenses	0.44%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The U.S. Government Fixed Income Securities Portfolio HC Advisors Shares USD ($)
1 Year	$ 45
3 Years	141
5 Years	246
10 Years	$ 555

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 32.58% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in fixed income securities issued or fully guaranteed by the U.S. Government, Federal Agencies, or sponsored agencies. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Securities in which the Portfolio may invest include bonds, notes and certificates of deposit. These may include securities issued by federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. Government. In general the portfolio will maintain aggregate characteristics similar to the Bloomberg Barclays U.S. Government Index. Securities held by the Portfolio will be rated investment grade or better by at least two rating agencies at the time of purchase if not rated by an agency, of comparable credit quality as determined by the Specialist Manager at the time of purchase. Overall credit quality of the Portfolio will be maintained at a level substantially equal to that of the Bloomberg Barclays U.S. Government Index. The Portfolio will attempt to be fully invested at all times in U.S. Government fixed income securities, but may hold cash positions at times to adjust the duration of the Portfolio to more closely approximate that of the Bloomberg Barclays U.S. Government Index, to replicate the interest rate sensitivity of the securities in the Bloomberg Barclays U.S. Government Index, or to approximate the exposure to cash in the Bloomberg Barclays U.S. Government Index from coupon payments, principal payments or called securities. The Portfolio intends to maintain an effective dollar weighted average portfolio maturity similar to that of the Bloomberg Barclays U.S. Government Index, which was 7.50 years as of June 30, 2018. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in U.S. fixed income securities issued or fully guaranteed by the U.S. Government, Federal Agencies, or sponsored agencies.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. This risk should be low for the Portfolio as it invests mainly in securities that are not callable.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

The chart and table below show how The U.S. Government Fixed Income Securities Portfolio has performed, and how its performance has varied, from year to year. The bar chart shows returns on a before-tax basis and gives some indication of risk by showing changes in the Portfolio’s HC Strategic Shares yearly performance for each full calendar year since the Portfolio’s HC Strategic Shares inception on December 6, 2010. The table accompanying the bar chart compares the Portfolio’s performance over time on a before and after-tax basis to that of a broad based market index. Of course, past performance, before and after taxes, does not indicate how the Portfolio will perform in the future. A full calendar year of performance is not yet available for the HC Advisors Shares class. The performance shown below is that of HC Strategic Shares and has not been adjusted to reflect HC Advisors Shares expenses, which are higher. If it had been adjusted, performance would have been lower.

<b>Year-by-Year Total Returns as of 12/31 </b>

The Portfolio’s HC Strategic Shares before-tax return for the period from January 1, 2018 through September 30, 2018 (non-annualized) was -1.79%.

HC Advisors Shares | The Inflation Protected Securities Portfolio

<b>The Inflation Protected Securities Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Inflation Protected Securities Portfolio is to provide inflation protection and income consistent with investment in inflation-indexed securities.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Inflation Protected Securities Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The Inflation Protected Securities Portfolio HC Advisors Shares
Management Fees	0.09%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.07%
Total Annual Portfolio Operating Expenses	0.41%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Inflation Protected Securities Portfolio HC Advisors Shares USD ($)
1 Year	$ 42
3 Years	132
5 Years	230
10 Years	$ 518

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 20.77% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in inflation-indexed bonds issued by the U.S. government and non-U.S. governments, their agencies and instrumentalities and corporations. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio may invest in non-investment grade securities (“junk bonds”). Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Treasury Inflation Protected Securities Index (“Barclays US TIPS Index”), which range, as of June 30, 2018, was between 1 and 29 years. The weighted average maturity of the Barclays US TIPS Index as of June 30, 2018 was 8.3 years. The Portfolio may invest in securities issued by foreign corporations. The Portfolio’s investments in non-U.S. governments and corporations may include securities issued in emerging markets countries.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Deflation Risk – Deflation risk is the possibility that prices throughout the economy decline over time – the opposite of inflation. If inflation is negative, the principal and income of an inflation-protected bond will decline and could result in losses.

• Inflation Indexed Bonds Risk – The principal value of an investment is not protected or otherwise guaranteed by virtue of the Portfolio’s investments in inflation-indexed bonds. Inflation-indexed bonds are fixed-income securities whose principal value is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.
  
  Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal value.
  
  The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates are tied to the relationship between nominal interest rates and the rate of inflation. If nominal interest rates increase at a faster rate than inflation, real interest rates may rise, leading to a decrease in value of inflation-indexed bonds. Short-term increases in inflation may lead to a decline in value. Inflation-indexed bonds issued by non-U.S. governments would be expected to be indexed to the inflation rates prevailing in those countries.

• Inflation Indexed Bonds Tax Risk – Any increase in the principal amount of an inflation-indexed security may be included for tax purposes in the Portfolio’s gross income, even though no cash attributable to such gross income has been received by the Portfolio. In such event, the Portfolio may be required to make annual distributions to shareholders that exceed the cash it has otherwise received. In order to pay such distributions, the Portfolio may be required to raise cash by selling portfolio investments. The sale of such investments could result in capital gains to the Portfolio and additional capital gain distributions to shareholders. In addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by the Portfolio may cause amounts previously distributed to shareholders in the taxable year as income to be characterized as a return of capital.

• Non-Investment-Grade Securities – Non-investment-grade securities, also referred to as “high-yield securities” or “junk bonds,” are debt securities that are rated lower than the four highest rating categories by a nationally recognized statistical rating organization (for example, lower than Baa3/P-2 by Moody’s Investors Service, Inc. (Moody’s) or below BBB–/A-2 by Standard & Poor’s) or are determined to be of comparable quality by the fund’s advisor. These securities are generally considered to be, on balance, predominantly speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation, and they will generally involve more credit risk than securities in the investment-grade categories. Non-investment-grade securities generally provide greater income and opportunity for capital appreciation than higher quality securities, but they also typically entail greater price volatility and principal and income risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the Morgan Stanley Capital International Europe, Australasia and Far East (“MSCI EAFE”) Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Deflation Risk – Deflation risk is the possibility that prices throughout the economy decline over time – the opposite of inflation. If inflation is negative, the principal and income of an inflation-protected bond will decline and could result in losses.

• Inflation Indexed Bonds Risk – The principal value of an investment is not protected or otherwise guaranteed by virtue of the Portfolio’s investments in inflation-indexed bonds. Inflation-indexed bonds are fixed-income securities whose principal value is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.
  
  Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal value.
  
  The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates are tied to the relationship between nominal interest rates and the rate of inflation. If nominal interest rates increase at a faster rate than inflation, real interest rates may rise, leading to a decrease in value of inflation-indexed bonds. Short-term increases in inflation may lead to a decline in value. Inflation-indexed bonds issued by non-U.S. governments would be expected to be indexed to the inflation rates prevailing in those countries.

• Inflation Indexed Bonds Tax Risk – Any increase in the principal amount of an inflation-indexed security may be included for tax purposes in the Portfolio’s gross income, even though no cash attributable to such gross income has been received by the Portfolio. In such event, the Portfolio may be required to make annual distributions to shareholders that exceed the cash it has otherwise received. In order to pay such distributions, the Portfolio may be required to raise cash by selling portfolio investments. The sale of such investments could result in capital gains to the Portfolio and additional capital gain distributions to shareholders. In addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by the Portfolio may cause amounts previously distributed to shareholders in the taxable year as income to be characterized as a return of capital.

• Non-Investment-Grade Securities – Non-investment-grade securities, also referred to as “high-yield securities” or “junk bonds,” are debt securities that are rated lower than the four highest rating categories by a nationally recognized statistical rating organization (for example, lower than Baa3/P-2 by Moody’s Investors Service, Inc. (Moody’s) or below BBB–/A-2 by Standard & Poor’s) or are determined to be of comparable quality by the fund’s advisor. These securities are generally considered to be, on balance, predominantly speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation, and they will generally involve more credit risk than securities in the investment-grade categories. Non-investment-grade securities generally provide greater income and opportunity for capital appreciation than higher quality securities, but they also typically entail greater price volatility and principal and income risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations.

HC Advisors Shares | The U.S. Corporate Fixed Income Securities Portfolio

<b>The U.S. Corporate Fixed Income Securities Portfolio </b>

<b>Investment Objective </b>

The investment objective of The U.S. Corporate Fixed Income Securities Portfolio is to provide a moderate and sustainable level of current income, consistent with the preservation of capital by investing primarily in a diversified portfolio of investment grade fixed income securities issued by U.S. corporations.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The U.S. Corporate Fixed Income Securities Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The U.S. Corporate Fixed Income Securities Portfolio HC Advisors Shares
Management Fees	0.13%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.08%
Acquired Fund Fees and Expenses	0.02%
Total Annual Portfolio Operating Expenses	0.48%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The U.S. Corporate Fixed Income Securities Portfolio HC Advisors Shares USD ($)
1 Year	$ 49
3 Years	154
5 Years	269
10 Years	$ 604

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 44.69% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e. at least 80% of net assets) in fixed income securities issued by U.S. corporations. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. In general, the Portfolio invests predominantly in investment grade fixed income securities and will maintain aggregate characteristics similar to the Bloomberg Barclays U.S. Corporate Index. Securities held by the Portfolio will be rated investment-grade or better by one of the established rating agencies or, if not rated by an agency, of comparable credit quality as determined by the Specialist Manager at the time of purchase. Securities held by the Portfolio which are downgraded below investment-grade by all ratings agencies may be retained up to a maximum market value of 5% of the Portfolio. Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Corporate Investment Grade Index, which range, as of June 30, 2018, was between 1 and 29 years. The weighted average maturity of the Bloomberg Barclays U.S. Corporate Investment Grade Index as of June 30, 2018 was 10.8 years. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in investment grade fixed income securities issued by U.S. corporations. The Portfolio may also invest up to 20% of its assets in municipal bonds (i.e., debt securities issued by municipalities and related entities). The Portfolio may invest in fixed income securities of foreign issuers.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Advisors Shares | The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio

<b>The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio </b>

<b>Investment Objective </b>

The investment objective of The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio is to seek to provide a moderate and sustainable level of current income, consistent with the preservation of capital by investing primarily in a diversified portfolio of publicly issued mortgage and asset backed securities.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio HC Advisors Shares
Management Fees	0.11%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.12%
Acquired Fund Fees and Expenses	0.03%
Total Annual Portfolio Operating Expenses	0.51%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio HC Advisors Shares USD ($)
1 Year	$ 52
3 Years	164
5 Years	285
10 Years	$ 640

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 17.13% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e. at least 80% of net assets) in U.S. mortgage and asset backed securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio invests predominantly in publicly issued, investment grade U.S. mortgage and asset backed securities and, in general, seeks to maintain aggregate characteristics similar to the Bloomberg Barclays U.S. Securitized Index. The Portfolio will seek to invest in U.S. dollar denominated agency and non-agency mortgage-backed securities backed by loans secured by residential, multifamily and commercial properties including, but not limited to: pass throughs, collateralized mortgage obligations (“CMOs”), real estate mortgage investment conduits (“REMICs”), stripped mortgage-backed securities (“SMBS”), project loans, construction loans, and adjustable rate mortgages. Income from MBS, ABS, CMO, REMIC and SMBS investments of the Portfolio will be taxed as ordinary income when distributed to shareholders unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in mortgage and asset backed securities. The Portfolio may also invest in U.S. Treasury and agency securities. Securities must be rated investment-grade or better by a nationally recognized credit rating agency at the time of purchase or, if not rated by an agency, of comparable credit quality as determined by the Specialist Manager at the time of purchase. The Portfolio may engage in transactions involving instruments such as option or futures contracts, both in order to hedge against fluctuations in the market value of the securities in which the Portfolio invests and to achieve market exposure pending investment and, in the case of asset-backed and similar securities, for investment purposes. Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Securitized Index, which has a weighted average maturity of 7.2 years as of June 30, 2018 and can vary between 1 and 9 years.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Advisors Shares | The Short-Term Municipal Bond Portfolio

<b>The Short-Term Municipal Bond Portfolio</b>

<b>Investment Objective </b>

The investment objective of The Short-Term Municipal Bond Portfolio is to provide a high level of current income exempt from Federal income tax, consistent with the preservation of capital.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Short-Term Municipal Bond Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The Short-Term Municipal Bond Portfolio HC Advisors Shares
Management Fees	0.18%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.15%
Acquired Fund Fees and Expenses	0.02%
Total Annual Portfolio Operating Expenses	0.60%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Short-Term Municipal Bond Portfolio HC Advisors Shares USD ($)
1 Year	$ 61
3 Years	192
5 Years	335
10 Years	$ 750

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 18.84% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e. at least 80% of net assets) in municipal bonds. The policy stated in the foregoing sentence is a fundamental policy and may not be changed without shareholder approval. Municipal bonds are debt securities issued by municipalities and related entities, the interest on which is exempt from Federal income tax so that they will qualify to pay “exempt-interest dividends” (“Municipal Securities”). The Portfolio intends to maintain a dollar-weighted effective average portfolio maturity of no longer than three years. The Portfolio invests primarily in securities that are rated in one of the top four rating categories of a nationally recognized statistical rating organization (“Baa” or higher by Moodys, “BBB” or higher by Standard & Poor’s) or, if unrated, that are determined by the Specialist Manager to be of comparable quality. Fixed income securities rated in the fourth highest rating category by a rating agency may have speculative characteristics. The Portfolio does not currently intend to invest in obligations, the interest on which is a preference item for purposes of the Federal alternative minimum tax. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in municipal bonds.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Tax Risk – Changes in Federal tax laws or regulations could change the tax-exempt status of income from any or all of the Portfolio’s municipal securities. In addition, short-term capital gains and a portion of any gain attributable to bonds purchased at market discount will be treated as ordinary income for Federal tax purposes.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – Municipal securities held by the Portfolio may be called (prepaid) before their maturity dates. This usually occurs as interest rates are declining. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. In addition, the Portfolio may lose price appreciation if a bond it holds is called earlier than scheduled.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Performance Bar Chart and Table </b><br/><br/> <b>Performance.</b>

The chart and table below show how The Short-Term Municipal Bond Portfolio has performed, and how its performance has varied, from year to year. The bar chart shows returns on a before-tax basis and gives some indication of risk by showing changes in the Portfolio’s HC Strategic Shares yearly performance for each full calendar year since the Portfolio’s HC Strategic Shares inception on March 1, 2006. The table accompanying the bar chart compares the Portfolio’s performance over time on a before and after-tax basis to that of a broad based market index. Of course, past performance, before and after taxes, does not indicate how the Portfolio will perform in the future.

HC Advisors Shares | The Intermediate Term Municipal Bond Portfolio

<b>The Intermediate Term Municipal Bond Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Intermediate Term Municipal Bond Portfolio is to provide a high level of current income exempt from Federal income tax, consistent with the preservation of capital.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares The Intermediate Term Municipal Bond Portfolio HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares The Intermediate Term Municipal Bond Portfolio HC Advisors Shares
Management Fees	0.27%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.08%
Total Annual Portfolio Operating Expenses	0.60%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes the reinvestment of all dividends and distributions in shares of the Portfolio, that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares The Intermediate Term Municipal Bond Portfolio HC Advisors Shares USD ($)
1 Year	$ 61
3 Years	192
5 Years	335
10 Years	$ 750

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 26.27% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of net assets) in municipal bonds. The policy stated in the foregoing sentence is a fundamental policy of the Portfolio and may not be changed without shareholder approval. Municipal bonds are debt securities issued by municipalities and related entities, the interest on which is exempt from Federal income tax so that they will qualify to pay “exempt-interest dividends” (“Municipal Securities”). Municipal Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, currently 2 to 20 years. Municipal Securities acquired for the Portfolio will generally be rated in one of the three highest rating categories assigned by one of the major independent rating agencies (“A” or higher by Moodys, or Standard & Poor’s), or are, in the view of the Specialist Manager, deemed to be of comparable quality. The Portfolio is, however, authorized to invest up to 15% of its assets in Municipal Securities that are rated in the fourth highest category and up to 10% of its assets in high yield securities (“junk bonds”). Fixed income securities rated in the fourth highest rating category by a rating agency may have speculative characteristics. The Portfolio is also authorized to invest in securities issued by other investment companies, such as ETFs and closed-end funds, that invest in Municipal Securities. Also, the Portfolio is authorized to invest up to 20% of its net assets in taxable instruments.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Tax Risk – Changes in Federal tax laws or regulations could change the tax-exempt status of income from any or all of the Portfolio’s municipal securities. In addition, short-term capital gains and a portion of any gain attributable to bonds purchased at market discount will be treated as ordinary income for Federal tax purposes.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – Municipal securities held by the Portfolio may be called (prepaid) before their maturity dates. This usually occurs as interest rates are declining. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. In addition, the Portfolio may lose price appreciation if a bond it holds is called earlier than scheduled.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. The prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health. Change in market interest rates will also affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Advisors Shares | THE INTERMEDIATE TERM MUNICIPAL BOND II PORTFOLIO

<b>The Intermediate Term Municipal Bond II Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Intermediate Term Municipal Bond II Portfolio is to provide as high a level of current income exempt from Federal income tax, as is consistent with the preservation of capital.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Advisors Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Advisors Shares THE INTERMEDIATE TERM MUNICIPAL BOND II PORTFOLIO HC Advisors Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Advisors Shares THE INTERMEDIATE TERM MUNICIPAL BOND II PORTFOLIO HC Advisors Shares
Management Fees	0.24%
Distribution and/or Service (12b-1) Fees	0.25%
Other Expenses	0.10%
Total Annual Portfolio Operating Expenses	0.59%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Advisors Shares THE INTERMEDIATE TERM MUNICIPAL BOND II PORTFOLIO HC Advisors Shares USD ($)
1 Year	$ 60
3 Years	189
5 Years	329
10 Years	$ 738

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 21.56% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of net assets) in municipal bonds. The policy stated in the foregoing sentence is a fundamental policy of the Portfolio and may not be changed without shareholder approval. Municipal bonds are debt securities issued by municipalities and related entities, the interest on which is exempt from Federal income tax, and include general obligation bonds and notes, revenue bonds and notes (including industrial revenue bonds and municipal lease obligations), as well as participation interests relating to such securities and are referred to as “Municipal Securities.” The Portfolio invests primarily in securities that are rated in one of the top four rating categories of a nationally recognized statistical rating organization (“Baa” or higher by Moodys, “BBB” or higher by Standard & Poor’s) or, if unrated, that are determined by the Specialist Manager to be of comparable quality. Municipal Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, currently 2 to 10 years. The Portfolio may invest in securities issued by other investment companies, including ETFs and closed-end funds, that invest in Municipal Securities.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Tax Risk – Changes in Federal tax laws or regulations could change the tax-exempt status of income from any or all of the Portfolio’s municipal securities. In addition, short-term capital gains and a portion of any gain attributable to bonds purchased at market discount will be treated as ordinary income for Federal tax purposes.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – Municipal Securities held by the Portfolio may be called (prepaid) before their maturity dates. This usually occurs as interest rates are declining. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. In addition, the Portfolio may lose price appreciation if a bond it holds is called earlier than scheduled.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

• Revenue Bonds Risk – Payments of interest and principal are made only from the revenues generated by a particular facility, class of facilities or the proceeds of a special tax, or other revenue source, and depends on the money earned by that source.

• Private Activity Bonds Risk – Municipalities and other public authorities issue private activity bonds to finance development of industrial facilities for use by a private enterprise. The private enterprise pays the principal and interest on the bond, and the issuer does not pledge its faith, credit and taxing power for repayment. The Portfolio’s investments may consist of private activity bonds that may subject certain shareholders to an alternative minimum tax.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The Value Equity Portfolio

<b>The Value Equity Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Value Equity Portfolio is to provide total return consisting of capital appreciation and current income.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Value Equity Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Value Equity Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.13%
Other Expenses	0.07%
Total Annual Portfolio Operating Expenses	0.20%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Value Equity Portfolio HC Strategic Shares USD ($)
1 Year	$ 20
3 Years	64
5 Years	113
10 Years	$ 255

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 58.60% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

The Portfolio is a diversified investment company that is designed to implement a value-oriented investment approach. A “value investor” seeks to select securities that trade for less than the intrinsic value of the issuing company, as measured by fundamental investment considerations such as earnings, book value and dividend paying ability. Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio may invest up to 20% of the total assets of the actively managed portion of the Portfolio in income-producing securities other than common stock, such as bonds, including those that are convertible into common stock. These income-producing securities may be of any quality or maturity. The Portfolio will focus its investments in equity securities of large and mid-capitalization issuers. As of the date of this Prospectus, companies with a market capitalization of between $2.5 billion and $34.7 billion would likely be included in the “mid cap” range. Up to 20% of the total assets of the total Portfolio may also be invested in securities issued by non-U.S. companies. The Portfolio may invest in securities issued by other investment companies, including Exchange-Traded Funds (“ETFs”) that invest in equity securities. The Portfolio may also invest in option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one investment subadviser (“Specialist Manager”). The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Value Investing Risk – An investment in the Portfolio cannot assure moderation of investment risk. There is no guarantee that a value stock is, in fact, undervalued, or that the market will ever recognize its true value.

• Mid Cap Risk – Mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.     The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The Institutional Value Equity Portfolio

<b>The Institutional Value Equity Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Institutional Value Equity Portfolio is to provide total return consisting of capital appreciation and current income.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Institutional Value Equity Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Institutional Value Equity Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.12%
Other Expenses	0.07%
Acquired Fund Fees and Expenses	0.02%
Total Annual Portfolio Operating Expenses	0.21%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Institutional Value Equity Portfolio HC Strategic Shares USD ($)
1 Year	$ 22
3 Years	68
5 Years	118
10 Years	$ 268

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 68.39% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

The Portfolio is a diversified investment company that is designed to implement a value-oriented investment approach. A “value investor” seeks to select securities that trade for less than the intrinsic value of the issuing company, as measured by fundamental investment considerations such as earnings, book value and dividend paying ability. Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio will focus its investments in equity securities of large and mid-capitalization issuers. As of the date of this Prospectus, companies with a market capitalization of between $2.5 billion and $34.7 billion would likely be included in the “mid cap” range. Up to 20% of the total assets of the actively managed portion of the Portfolio may be invested in income-producing securities other than common stock, such as bonds, including those that are convertible into common stock. These income-producing securities may be of any quality or maturity. Up to 20% of the total assets of the total Portfolio may also be invested in securities issued by non-U.S. companies. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities. Consistent with their respective investment styles, the Portfolio’s Specialist Managers may use option or futures contracts in order to pursue their investment objectives, gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Value Investing Risk – An investment in the Portfolio cannot assure moderation of investment risk. There is no guarantee that a value stock is, in fact, undervalued, or that the market will ever recognize its true value.

• Mid Cap Risk – Mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The Growth Equity Portfolio

<b>The Growth Equity Portfolio</b>

<b>Investment Objective </b>

The investment objective of The Growth Equity Portfolio is to provide capital appreciation,

with income as a secondary consideration.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Growth Equity Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Growth Equity Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.18%
Other Expenses	0.07%
Total Annual Portfolio Operating Expenses	0.25%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Growth Equity Portfolio HC Strategic Shares USD ($)
1 Year	$ 26
3 Years	80
5 Years	141
10 Years	$ 318

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 39.77% of the average value of its portfolio.

<b>Principal Investment Strategies</b>

The Portfolio is a diversified investment company that is designed to implement a growth-oriented investment approach. “Growth investing” means that securities acquired for the Portfolio can be expected to have above-average potential for growth in revenue and earnings. Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio may invest up to 20% of the total assets of the actively managed portion of the Portfolio in income-producing securities other than common stock, such as bonds, including those that are convertible into common stock. These income-producing securities may be of any quality or maturity. The Portfolio will focus its investments in equity securities of large and mid-capitalization issuers. As of the date of this Prospectus, companies with a market capitalization of between $2.5 billion and $34.7 billion would likely be included in the “mid cap” range. Up to 20% of the total assets of the total Portfolio may also be invested in securities issued by non-U.S. companies. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities. Although some of the equity securities in which the Portfolio will invest are expected to be dividend paying issues, income is a secondary consideration in the stock selection process. Accordingly, dividends paid by this Portfolio can generally be expected to be lower than those paid by The Value Equity Portfolio. Consistent with their respective investment styles, the Portfolio’s Specialist Managers may use option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Growth Investing Risk – An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty. Growth stocks typically have little or no dividend income to cushion the effect of adverse market conditions. In addition, growth stocks may be particularly volatile in the event of earnings disappointments or other financial difficulties experienced by the issuer.

• Mid Cap Risk – Mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The Institutional Growth Equity Portfolio

<b>The Institutional Growth Equity Portfolio</b>

<b>Investment Objective </b>

The investment objective of The Institutional Growth Equity Portfolio is to provide capital appreciation,

with income as a secondary consideration.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Institutional Growth Equity Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Institutional Growth Equity Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.17%
Other Expenses	0.07%
Total Annual Portfolio Operating Expenses	0.24%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Institutional Growth Equity Portfolio HC Strategic Shares USD ($)
1 Year	$ 25
3 Years	77
5 Years	135
10 Years	$ 306

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 43.36% of the average value of its portfolio.

<b>Principal Investment Strategies</b>

The Portfolio is a diversified investment company that is designed to implement a growth-oriented investment approach. “Growth investing” means that securities acquired for the Portfolio can be expected to have above-average potential for growth in revenue and earnings. Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio may invest up to 20% of the total assets of the actively managed portion of the Portfolio in income-producing securities other than common stock, such as bonds, including those that are convertible into common stock. These income-producing securities may be of any quality or maturity. The Portfolio will focus its investments in equity securities of large and mid-capitalization issuers. As of the date of this Prospectus, companies with a market capitalization of between $2.5 billion and $34.7 billion would likely be included in the “mid cap” range. Up to 20% of the total assets of the total Portfolio may also be invested in securities issued by non-U.S. companies. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities. Although some of the equity securities in which the Portfolio will invest are expected to be dividend paying issues, income is a secondary consideration in the stock selection process. Accordingly, dividends paid by this Portfolio can generally be expected to be lower than those paid by The Institutional Value Equity Portfolio. Consistent with their respective investment styles, the Portfolio’s Specialist Managers may use option or futures contracts in order to pursue their investment objectives, gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in foreign currencies. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.     Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Growth Investing Risk – An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty. Growth stocks typically have little or no dividend income to cushion the effect of adverse market conditions. In addition, growth stocks may be particularly volatile in the event of earnings disappointments or other financial difficulties experienced by the issuer.

• Mid Cap Risk – Mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.     Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.     Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Growth Investing Risk – An investment in growth stocks may be susceptible to rapid price swings, especially during periods of economic uncertainty. Growth stocks typically have little or no dividend income to cushion the effect of adverse market conditions. In addition, growth stocks may be particularly volatile in the event of earnings disappointments or other financial difficulties experienced by the issuer.

• Mid Cap Risk – Mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.     Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The Small Capitalization - Mid Capitalization Equity Portfolio

<b>The Small Capitalization – Mid Capitalization Equity Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Small Capitalization – Mid Capitalization Equity Portfolio is to provide long-term capital appreciation.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Small Capitalization - Mid Capitalization Equity Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Small Capitalization - Mid Capitalization Equity Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.56%
Other Expenses	0.11%
Acquired Fund Fees and Expenses	0.03%
Total Annual Portfolio Operating Expenses	0.70%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Small Capitalization - Mid Capitalization Equity Portfolio HC Strategic Shares USD ($)
1 Year	$ 72
3 Years	224
5 Years	390
10 Years	$ 871

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 61.65% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities of small-capitalization and mid-capitalization issuers. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio, a diversified investment company, is designed to invest primarily in equity securities of U.S. issuers which have market capitalizations that are comparable to the capitalization of companies in the Russell 3000^® Index that are classified as “Small” or “Medium” at the time of purchase. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of “small cap” and/or “mid cap” issuers. The Portfolio will invest in both dividend paying securities and securities that do not pay dividends. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities. As of the date of this Prospectus, the market capitalization range of companies in the Russell 3000^® Index that were classified as “Small” or “Medium” was between approximately $159 million and $34.7 billion.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.     Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors.
  
  Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.     Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors.
  
  Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The Institutional Small Capitalization - Mid Capitalization Equity Portfolio

<b>The Institutional Small Capitalization – Mid Capitalization Equity Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Institutional Small Capitalization – Mid Capitalization Equity Portfolio is to provide long-term capital appreciation.

<b>Fees and Expenses </b>

The fee table below describes the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Institutional Small Capitalization - Mid Capitalization Equity Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Institutional Small Capitalization - Mid Capitalization Equity Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.45%
Other Expenses	0.09%
Acquired Fund Fees and Expenses	0.01%
Total Annual Portfolio Operating Expenses	0.55%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your costs would be:

Expense Example	HC Strategic Shares The Institutional Small Capitalization - Mid Capitalization Equity Portfolio HC Strategic Shares USD ($)
1 Year	$ 56
3 Years	176
5 Years	307
10 Years	$ 689

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 95.15% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities of small-capitalization and mid-capitalization issuers. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio, a diversified investment company, is designed to invest primarily in equity securities of U.S. issuers which have market capitalizations that are comparable to the capitalization of companies in the Russell 3000^® Index that are classified as “Small” or “Medium” at the time of purchase. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of “small cap” and/or “mid cap” issuers. The Portfolio will invest in both dividend paying securities and securities that do not pay dividends. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities. As of July 31, 2018, the market capitalization range of companies in the Russell 3000^® Index that were classified as “Small” or “Medium” was between approximately $159 million and $34.7 billion.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors.
  
  Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The Real Estate Securities Portfolio

<b>The Real Estate Securities Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Real Estate Securities Portfolio is to provide total return consisting of both capital appreciation and current income.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Real Estate Securities Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Real Estate Securities Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.67%
Other Expenses	0.08%
Acquired Fund Fees and Expenses	0.03%
Total Annual Portfolio Operating Expenses	0.78%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Real Estate Securities Portfolio HC Strategic Shares USD ($)
1 Year	$ 80
3 Years	249
5 Years	433
10 Years	$ 966

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 49.59% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in a portfolio of equity and debt securities issued by U.S. and non-U.S. real estate-related companies. Companies known as real estate investment trusts (REITs) and other real estate operating companies whose value is derived from ownership, development and management of underlying real estate properties are considered to be real estate-related companies. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio’s permissible investments include equity and equity-related securities of real estate-related companies, including common stock, preferred stock, convertible securities, warrants, options, depositary receipts and other similar equity equivalents. The Portfolio also may invest in fixed income securities, including debt securities, mortgage-backed securities and high yield debt (“junk bonds”). The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in securities issued by real estate-related companies. The Portfolio may also invest in companies which are located in emerging markets countries, as well as companies of any market capitalization.

Consistent with its investment style, the Portfolio’s Specialist Manager may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

The Portfolio is classified as a non-diversified fund, which means that the Portfolio is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as diversified.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

• Non-Diversification Risk – The Portfolio is classified as a non-diversified management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). This means that the Portfolio may invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as a diversified management investment company. Because the Portfolio may invest a relatively high percentage of its assets in a limited number of positions, the Portfolio’s performance may be more vulnerable to changes in the market value of a single position and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.     Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Real Estate Investing Risk.

• Real Estate Markets and REIT Risk – Investments in the Portfolio will be closely linked to the performance of the real estate markets. Property values may fall due to increasing vacancies or declining rents resulting from unanticipated economic, legal, cultural or technological developments. REIT prices may also fall because of the failure of borrowers to pay their loans and/or poor management. The value of real estate (and real estate securities) may also be affected by increases in property taxes and changes in tax laws and interest rates. The value of securities of companies that service the real estate industry may also be affected by such risks. To the extent that the Portfolio invests in REITs and real estate partnerships, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired REITs and real estate partnerships. Investments in REITs and real estate partnerships (if any) may cause a greater portion of the Portfolio’s distributions to be taxable as ordinary income.

• Industry Concentration Risk – Because the Portfolio concentrates its investments in real estate securities, it may be subject to greater risks of loss as a result of economic, business or other developments than a fund representing a broader range of industries. The Portfolio may be subject to risks associated with direct ownership of real estate, such as changes in economic conditions, interest rates, availability of mortgage funds, property values, increases in property taxes and operating expenses, increased competition, environmental problems, changes in zoning laws and natural disasters.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the Morgan Stanley Capital International Europe, Australasia and Far East (“MSCI EAFE”) Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Extension Risk – Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Performance Bar Chart and Table</b><br/><br/><b>Performance.</b>

The chart and table below show how The Real Estate Securities Portfolio has performed, and how its performance has varied, from year to year. The bar chart shows returns on a before-tax basis and gives some indication of risk by showing changes in the Portfolio’s yearly performance for each calendar year since the Portfolio’s inception on May 21, 2009 through December 31, 2013. Because the Portfolio was redeemed in full on June 30, 2013 and was reactivated on September 12, 2013, the performance information shown in the bar chart for 2013 reflects the combination of cumulative returns for each period when the Strategic Shares had operations. The performance table also shows the average annual total returns for the one- year, five-year and since inception periods (May 21, 2009) ended December 31, 2015 and reflects returns for the periods when the Strategic Shares had operations. Accordingly, the Portfolio’s performance in the bar chart and table may not be comparable to the performance of other mutual funds. The table accompanying the bar chart compares the Portfolio’s performance over time on a before and after-tax basis to that of a broad based market index. Of course, past performance, before and after taxes, does not indicate how the Portfolio will perform in the future.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 49.59% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in a portfolio of equity and debt securities issued by U.S. and non-U.S. real estate-related companies. Companies known as real estate investment trusts (REITs) and other real estate operating companies whose value is derived from ownership, development and management of underlying real estate properties are considered to be real estate-related companies. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio’s permissible investments include equity and equity-related securities of real estate-related companies, including common stock, preferred stock, convertible securities, warrants, options, depositary receipts and other similar equity equivalents. The Portfolio also may invest in fixed income securities, including debt securities, mortgage-backed securities and high yield debt (“junk bonds”). The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in securities issued by real estate-related companies. The Portfolio may also invest in companies which are located in emerging markets countries, as well as companies of any market capitalization.

Consistent with its investment style, the Portfolio’s Specialist Manager may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

The Portfolio is classified as a non-diversified fund, which means that the Portfolio is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as diversified.

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

• Non-Diversification Risk – The Portfolio is classified as a non-diversified management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). This means that the Portfolio may invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as a diversified management investment company. Because the Portfolio may invest a relatively high percentage of its assets in a limited number of positions, the Portfolio’s performance may be more vulnerable to changes in the market value of a single position and more susceptible to risks associated with a single economic, political or regulatory occurrence than a diversified fund.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.     Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Real Estate Investing Risk.

• Real Estate Markets and REIT Risk – Investments in the Portfolio will be closely linked to the performance of the real estate markets. Property values may fall due to increasing vacancies or declining rents resulting from unanticipated economic, legal, cultural or technological developments. REIT prices may also fall because of the failure of borrowers to pay their loans and/or poor management. The value of real estate (and real estate securities) may also be affected by increases in property taxes and changes in tax laws and interest rates. The value of securities of companies that service the real estate industry may also be affected by such risks. To the extent that the Portfolio invests in REITs and real estate partnerships, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired REITs and real estate partnerships. Investments in REITs and real estate partnerships (if any) may cause a greater portion of the Portfolio’s distributions to be taxable as ordinary income.

• Industry Concentration Risk – Because the Portfolio concentrates its investments in real estate securities, it may be subject to greater risks of loss as a result of economic, business or other developments than a fund representing a broader range of industries. The Portfolio may be subject to risks associated with direct ownership of real estate, such as changes in economic conditions, interest rates, availability of mortgage funds, property values, increases in property taxes and operating expenses, increased competition, environmental problems, changes in zoning laws and natural disasters.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the Morgan Stanley Capital International Europe, Australasia and Far East (“MSCI EAFE”) Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Extension Risk – Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

The chart and table below show how The Real Estate Securities Portfolio has performed, and how its performance has varied, from year to year. The bar chart shows returns on a before-tax basis and gives some indication of risk by showing changes in the Portfolio’s yearly performance for each calendar year since the Portfolio’s inception on May 21, 2009 through December 31, 2013. Because the Portfolio was redeemed in full on June 30, 2013 and was reactivated on September 12, 2013, the performance information shown in the bar chart for 2013 reflects the combination of cumulative returns for each period when the Strategic Shares had operations. The performance table also shows the average annual total returns for the one- year, five-year and since inception periods (May 21, 2009) ended December 31, 2015 and reflects returns for the periods when the Strategic Shares had operations. Accordingly, the Portfolio’s performance in the bar chart and table may not be comparable to the performance of other mutual funds. The table accompanying the bar chart compares the Portfolio’s performance over time on a before and after-tax basis to that of a broad based market index. Of course, past performance, before and after taxes, does not indicate how the Portfolio will perform in the future.

HC Strategic Shares | The Commodity Returns Strategy Portfolio

<b>The Commodity Returns Strategy Portfolio</b>

<b>Investment Objective</b>

The investment objective of The Commodity Returns Strategy Portfolio is to provide capital appreciation.

<b>Fees and Expenses</b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Commodity Returns Strategy Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Commodity Returns Strategy Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.29%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your costs would be:

Expense Example	HC Strategic Shares The Commodity Returns Strategy Portfolio HC Strategic Shares USD ($)
1 Year	$ 43
3 Years	135
5 Years	235
10 Years	$ 530

<b>Portfolio Turnover</b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 28.82% of the average value of its portfolio.

<b>Principal Investment Strategies</b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily in a diversified portfolio of commodity-related investments including securities issued by companies in commodity-related industries, commodity-linked structured notes (derivative debt instruments with principal and/or coupon payments linked to the performance of commodity indices) and other similar derivative instruments, investment vehicles that invest in commodities and commodity-related instruments. Securities of companies in commodities-related industries may include common stocks, depositary receipts, preferred securities, rights to subscribe for or purchase any such securities, warrants, convertible securities and other equity and commodity-linked securities issued by such companies. For this purpose, commodities are assets that have tangible properties, such as oil, metal and agricultural products. Commodity-related industries include, but are not limited to: (i) those directly engaged in the production of commodities, such as minerals, metals, agricultural commodities, chemicals, pulp and paper, building materials, oil and gas, other energy or natural resources, and (ii) companies that provide services to commodity producers. The Portfolio considers a company to be in a commodity-related industry if, as determined by the relevant Specialist Manager, at least 50% of the company’s assets, revenues or net income are derived from, or related to, such activities. The Portfolio will invest more than 25% of its assets in securities issued by companies in commodity-related industries. The Portfolio may invest without limitation in foreign securities, including securities issued by companies in emerging markets. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in foreign currencies and to hedge against fluctuations in the relative value of the currencies in which securities held by the Portfolio are denominated. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in commodity-related investments. The Portfolio also intends to gain exposure to commodity markets by investing a portion of its assets in two wholly-owned subsidiaries organized under the laws of the Cayman Islands (the “Subsidiaries”).

The Subsidiaries may invest without limitation in commodity-linked derivative instruments, such as swaps, futures and options. The Portfolio may invest in commodity swap, interest rate swap, variance swap and total return swap agreements and the Portfolio maintains liquid assets sufficient to cover the full notional value of any such swap positions. The Subsidiaries may also invest in debt securities, some of which are intended to serve as margin or collateral for the Subsidiaries’ derivatives positions, and other investment vehicles that invest in commodities and commodity-related instruments. The Subsidiaries are managed by the same Specialist Managers that advise the Portfolio.

The Portfolio may invest in equity and fixed income securities and may invest in companies of any market capitalization. Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that the Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks</b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Commodity-Related Investing Risks.    Investment in commodity-related securities involves the following risks:

• Commodity-Related Securities Risk – The securities of companies in commodity-related industries may underperform the stock market as a whole. The stock prices of such companies may also experience greater price volatility than other types of common stocks. Securities issued by companies in commodity-related industries are sensitive to changes in the supply and demand for, and thus the prices of, commodities. Additionally, the values of securities issued by commodity-related companies may be affected by factors affecting a particular industry or commodity.

• Commodity-Related Investment Risk – Exposure to the commodities markets may subject the Portfolio to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, interest rate changes or events affecting a particular commodity or industry, such as political instability or conflict, international economic and regulatory developments, embargoes and tariffs, and drought, floods and other weather-related events.

• Industry Concentration Risk – The Portfolio concentrates its investments in commodity-related industries. The focus of the Portfolio on a specific group of related industries my present more risks than if the Portfolio were more broadly diversified over numerous unrelated industries. A downturn in commodity-related industries would have a larger impact on the Portfolio than on an investment company that does not concentrate in such industries. At times, the performance of the Portfolio’s investments in commodity-related industries may lag the performance of other industries or the broader market as a whole.

• Subsidiary Risk – The commodity-related instruments held by the Subsidiaries are subject to the same risks that apply to similar investments if held directly by the Portfolio (see “Commodities Related Investment Risk” above). The Subsidiaries are not registered under the Investment Company Act and are not subject to all of the requirements and protections of that Act. However, the Portfolio wholly owns and controls the Subsidiaries, and the Board of Trustees has responsibility for overseeing the investment activities of the Portfolio, including its investment in the Subsidiaries. Changes in the laws of the United States and/or the Cayman Islands could adversely affect the Subsidiaries and/or the Portfolio.

• Commodity-Related Investment Tax Risk – The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Portfolio from certain commodity-linked derivatives was treated as non-qualifying income, the Portfolio might fail to qualify as a regulated investment company and/or be subject to federal income tax at the Portfolio level. Should the Internal Revenue Service (“IRS”) issue guidance, or Congress enact legislation, that adversely affects the tax treatment of commodity-linked notes or the Subsidiaries, it could, among other consequences, limit the Portfolio’s ability to pursue its investment strategy. For example, in September, 2016, the IRS released guidance stating that it would no longer issue rulings on any matter relating to the treatment of an entity as a Regulated Investment Company (“RIC”) if the matter would require a determination of whether a financial instrument or position is a security under the 1940 Act. To date, the Portfolio has not invested in any commodity-linked notes or other commodity-linked derivatives at the Portfolio level, although it retains the ability to make such investments in the future provided that such investments will not disqualify it for tax treatment as a RIC (or unless the Board determines that such disqualification is in the best interests of shareholders).

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Non-Investment Grade Securities Risk –  Non-investment grade securities are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. Such securities may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Swaps Risks – The use of swaps is a highly specialized activity which involves investment techniques, risk analyses and tax planning different from those associated with ordinary portfolio securities transactions. Swap transactions can result in sizeable realized and unrealized capital gains and losses relative to the gains and losses from the Portfolio’s direct investments in securities and short sales. Transactions in swaps can involve greater risks than if the Portfolio had invested in securities directly since, in addition to general market risks, swaps may be leveraged and are also subject to liquidity risk, counterparty risk, credit risk and valuation risk. Regulators also may impose limits on an entity’s or group of entities’ positions in certain swaps.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily in a diversified portfolio of commodity-related investments including securities issued by companies in commodity-related industries, commodity-linked structured notes (derivative debt instruments with principal and/or coupon payments linked to the performance of commodity indices) and other similar derivative instruments, investment vehicles that invest in commodities and commodity-related instruments. Securities of companies in commodities-related industries may include common stocks, depositary receipts, preferred securities, rights to subscribe for or purchase any such securities, warrants, convertible securities and other equity and commodity-linked securities issued by such companies. For this purpose, commodities are assets that have tangible properties, such as oil, metal and agricultural products. Commodity-related industries include, but are not limited to: (i) those directly engaged in the production of commodities, such as minerals, metals, agricultural commodities, chemicals, pulp and paper, building materials, oil and gas, other energy or natural resources, and (ii) companies that provide services to commodity producers. The Portfolio considers a company to be in a commodity-related industry if, as determined by the relevant Specialist Manager, at least 50% of the company’s assets, revenues or net income are derived from, or related to, such activities. The Portfolio will invest more than 25% of its assets in securities issued by companies in commodity-related industries. The Portfolio may invest without limitation in foreign securities, including securities issued by companies in emerging markets. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in foreign currencies and to hedge against fluctuations in the relative value of the currencies in which securities held by the Portfolio are denominated. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in commodity-related investments. The Portfolio also intends to gain exposure to commodity markets by investing a portion of its assets in two wholly-owned subsidiaries organized under the laws of the Cayman Islands (the “Subsidiaries”).

The Subsidiaries may invest without limitation in commodity-linked derivative instruments, such as swaps, futures and options. The Portfolio may invest in commodity swap, interest rate swap, variance swap and total return swap agreements and the Portfolio maintains liquid assets sufficient to cover the full notional value of any such swap positions. The Subsidiaries may also invest in debt securities, some of which are intended to serve as margin or collateral for the Subsidiaries’ derivatives positions, and other investment vehicles that invest in commodities and commodity-related instruments. The Subsidiaries are managed by the same Specialist Managers that advise the Portfolio.

The Portfolio may invest in equity and fixed income securities and may invest in companies of any market capitalization. Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that the Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style.

In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Commodity-Related Investing Risks.    Investment in commodity-related securities involves the following risks:

• Commodity-Related Securities Risk – The securities of companies in commodity-related industries may underperform the stock market as a whole. The stock prices of such companies may also experience greater price volatility than other types of common stocks. Securities issued by companies in commodity-related industries are sensitive to changes in the supply and demand for, and thus the prices of, commodities. Additionally, the values of securities issued by commodity-related companies may be affected by factors affecting a particular industry or commodity.

• Commodity-Related Investment Risk – Exposure to the commodities markets may subject the Portfolio to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, interest rate changes or events affecting a particular commodity or industry, such as political instability or conflict, international economic and regulatory developments, embargoes and tariffs, and drought, floods and other weather-related events.

• Industry Concentration Risk – The Portfolio concentrates its investments in commodity-related industries. The focus of the Portfolio on a specific group of related industries my present more risks than if the Portfolio were more broadly diversified over numerous unrelated industries. A downturn in commodity-related industries would have a larger impact on the Portfolio than on an investment company that does not concentrate in such industries. At times, the performance of the Portfolio’s investments in commodity-related industries may lag the performance of other industries or the broader market as a whole.

• Subsidiary Risk – The commodity-related instruments held by the Subsidiaries are subject to the same risks that apply to similar investments if held directly by the Portfolio (see “Commodities Related Investment Risk” above). The Subsidiaries are not registered under the Investment Company Act and are not subject to all of the requirements and protections of that Act. However, the Portfolio wholly owns and controls the Subsidiaries, and the Board of Trustees has responsibility for overseeing the investment activities of the Portfolio, including its investment in the Subsidiaries. Changes in the laws of the United States and/or the Cayman Islands could adversely affect the Subsidiaries and/or the Portfolio.

• Commodity-Related Investment Tax Risk – The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Portfolio from certain commodity-linked derivatives was treated as non-qualifying income, the Portfolio might fail to qualify as a regulated investment company and/or be subject to federal income tax at the Portfolio level. Should the Internal Revenue Service (“IRS”) issue guidance, or Congress enact legislation, that adversely affects the tax treatment of commodity-linked notes or the Subsidiaries, it could, among other consequences, limit the Portfolio’s ability to pursue its investment strategy. For example, in September, 2016, the IRS released guidance stating that it would no longer issue rulings on any matter relating to the treatment of an entity as a Regulated Investment Company (“RIC”) if the matter would require a determination of whether a financial instrument or position is a security under the 1940 Act. To date, the Portfolio has not invested in any commodity-linked notes or other commodity-linked derivatives at the Portfolio level, although it retains the ability to make such investments in the future provided that such investments will not disqualify it for tax treatment as a RIC (or unless the Board determines that such disqualification is in the best interests of shareholders).

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Non-Investment Grade Securities Risk –  Non-investment grade securities are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. Such securities may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

Transactions in swaps can involve greater risks than if the Portfolio had invested in securities directly since, in addition to general market risks, swaps may be leveraged and are also subject to liquidity risk, counterparty risk, credit risk and valuation risk. Regulators also may impose limits on an entity’s or group of entities’ positions in certain swaps.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The ESG Growth Portfolio

<b>The ESG Growth Portfolio</b>

<b>Investment Objective</b>

The ESG Growth Portfolio seeks to maximize total return while emphasizing environmental, social and governance (“ESG”) focused investments.

<b>Fees and Expenses</b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The ESG Growth Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The ESG Growth Portfolio HC Strategic Shares
Management Fees	0.22%
Other Expenses	0.12%
Total Annual Portfolio Operating Expenses	0.34%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The ESG Growth Portfolio HC Strategic Shares USD ($)
1 Year	$ 35
3 Years	109
5 Years	191
10 Years	$ 431

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in Total Annual Portfolio Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 15.54% of the average value of its portfolio.

<b>Principal Investment Strategies</b>

Under normal circumstances, the Portfolio seeks to achieve its total return objective, which includes a combination of capital appreciation and income, by investing primarily in equity securities. The Portfolio is permitted to invest in any equity security, which includes securities issued by other investment companies, including exchange traded funds (“ETFs”) and securities issued by one or more of the other portfolios of HC Capital Trust. The Portfolio may invest in companies of any market capitalization. Further, under the supervision of the Adviser, environmental, social and governance criteria (“ESG Factors) will be integrated into the Portfolio’s security selection process through the application of non-financial criteria (“ESG Screens”). The ESG Screens used by the Portfolio are determined with the use of third party data and ESG rating agencies which take into account a company’s performance around environmental, social and corporate governance practices. These may include (but are not limited to) such themes as climate change, resource efficiency, labor standards, product and service safety, community engagement, board policies, and corporate structure. The Portfolio seeks to avoid investment in securities issued by companies that have not demonstrated a commitment to ESG issues. Additionally, the Portfolio’s ESG Screens may not necessarily be applied to investments in derivatives, certain fixed income investments and other investments where in the Advisor’s opinion ESG Factors are not applicable or it is not possible to implement them. The ESG Screens will be applied by the Specialist Managers that manage the Portfolio under the direction of the Adviser. The ESG Screens used by each Specialist Manager may differ from one another.

The Portfolio may also invest without limitation in fixed income securities of all types and without regard to duration or investment ratings. Fixed income investments may include corporate debt, including high yield or “junk bonds,” structured notes, asset backed securities and similar synthetic securities, U.S. treasuries and short-term money market instruments or other cash equivalents.

The Portfolio is permitted to invest in securities issued by companies domiciled anywhere in the world and denominated in any currency, without limitation. The Portfolio may also invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues.

<b>Principal Investment Risks</b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk.    The Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the broad range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Investment in Other Investment Companies Risk – To the extent that the Portfolio acquires securities issued by other investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies. Securities issued by other investment companies, including ETFs, are also equity securities and, as such, are subject to Market Risk and Management Risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively do so.

• ESG Investing Risk.    The Portfolio seeks to avoid investment in securities issued by companies that have not demonstrated a commitment to ESG issues. The Portfolio’s use of ESG Factors in making investment decisions may include the following risks.

• Risk of Excluding Performing Companies – The Portfolio’s ESG policy may cause it to perform differently than funds that do not have an ESG focus. The Portfolio’s ESG focus may result in the Portfolio foregoing opportunities to buy or sell certain securities when it might otherwise be advantageous to do so.

• Information Risk – The ESG Screens used by the Portfolio are determined in part through the use of third party data and ESG rating agencies. Information relating to the ESG performance of the companies in which the Portfolio may invest may not be complete, accurate or readily available. This fact may negatively impact the effectiveness of the ESG Screens.

• Foreign Investment Risk. – Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities. Additionally, risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time. The Portfolio generally considers “emerging markets” countries to be those included in the MSCI Emerging Markets Index.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income.

• Extension Risk – Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Asset-Backed/Mortgage-Backed Securities Risk –  The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Risks Associated with Investments in Futures.    The Portfolio is permitted to invest in futures. Investment in futures depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Futures involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks.
  
  The value of futures may rise or fall more rapidly than other investments and there is a risk that the Portfolio may lose more than the original amount invested in futures. Futures also involve the risk that other parties to the futures contract may fail to meet their obligations, which could cause losses to the Portfolio. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances. Compared to other types of investments, futures may be harder to value and may also be less tax efficient. To the extent that the Portfolio uses futures to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the futures instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of futures may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Thinly traded Securities.    The Portfolio may invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues. Investment in these securities involve the following risks:

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Valuation Risk – When market quotations are not readily available or are deemed to be unreliable, the Portfolio values its investments at fair value as determined in good faith pursuant to policies and procedures approved by the Board of Trustees. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets, or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Investment in Other Investment Companies Risk – To the extent that the Portfolio acquires securities issued by other investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies. Securities issued by other investment companies, including ETFs, are also equity securities and, as such, are subject to Market Risk and Management Risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively do so.

• ESG Investing Risk.    The Portfolio seeks to avoid investment in securities issued by companies that have not demonstrated a commitment to ESG issues. The Portfolio’s use of ESG Factors in making investment decisions may include the following risks.

• Risk of Excluding Performing Companies – The Portfolio’s ESG policy may cause it to perform differently than funds that do not have an ESG focus. The Portfolio’s ESG focus may result in the Portfolio foregoing opportunities to buy or sell certain securities when it might otherwise be advantageous to do so.

• Information Risk – The ESG Screens used by the Portfolio are determined in part through the use of third party data and ESG rating agencies. Information relating to the ESG performance of the companies in which the Portfolio may invest may not be complete, accurate or readily available. This fact may negatively impact the effectiveness of the ESG Screens.

• Foreign Investment Risk. – Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities. Additionally, risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time. The Portfolio generally considers “emerging markets” countries to be those included in the MSCI Emerging Markets Index.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income.

• Extension Risk – Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Asset-Backed/Mortgage-Backed Securities Risk –  The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Risks Associated with Investments in Futures.    The Portfolio is permitted to invest in futures. Investment in futures depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Futures involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks.
  
  The value of futures may rise or fall more rapidly than other investments and there is a risk that the Portfolio may lose more than the original amount invested in futures. Futures also involve the risk that other parties to the futures contract may fail to meet their obligations, which could cause losses to the Portfolio. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances. Compared to other types of investments, futures may be harder to value and may also be less tax efficient. To the extent that the Portfolio uses futures to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the futures instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of futures may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Thinly traded Securities.    The Portfolio may invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues. Investment in these securities involve the following risks:

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Valuation Risk – When market quotations are not readily available or are deemed to be unreliable, the Portfolio values its investments at fair value as determined in good faith pursuant to policies and procedures approved by the Board of Trustees. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets, or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

HC Strategic Shares | The Catholic SRI Growth Portfolio

<b>The Catholic SRI Growth Portfolio</b>

<b>Investment Objective</b>

The Catholic SRI Growth Portfolio seeks to maximize total return subject to emphasizing socially responsible investments.

<b>Fees and Expenses</b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Catholic SRI Growth Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Catholic SRI Growth Portfolio HC Strategic Shares
Management Fees	0.21%
Other Expenses	0.21%
Total Annual Portfolio Operating Expenses	0.42%

<b>Example:</b>

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your costs would be:

Expense Example	HC Strategic Shares The Catholic SRI Growth Portfolio HC Strategic Shares USD ($)
1 Year	$ 43
3 Years	135
5 Years	235
10 Years	$ 530

<b>Portfolio Turnover</b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in Total Annual Portfolio Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 17.01% of the average value of its portfolio.

<b>Principal Investment Strategies</b>

Under normal circumstances, the Portfolio seeks to achieve its objective, which includes a combination of capital appreciation and income, by investing primarily in equity securities while retaining the flexibility to invest in fixed income securities. In addition to equity and fixed income securities, the Portfolio may invest in other instruments, including, but not limited to, derivatives. The Portfolio is permitted to invest in any equity security, which includes securities issued by other investment companies, including exchange traded funds (“ETFs”) and securities issued by one or more of the other portfolios of HC Capital Trust. The Portfolio may invest in companies of any market capitalization.

Further, under the supervision of the Adviser, the Portfolio integrates a range of social and moral concerns into its security selection process. These issues may include protecting human life; promoting human dignity; reducing arms production; pursuing economic justice; protecting the environment, and encouraging corporate responsibility. This will be accomplished with reference to the principles contained in the United States Conference of Catholic Bishops’ (“USCCB”) Socially Responsible Investing Guidelines (“Social Guidelines”). Potential investments for the Portfolio are selected for financial soundness and evaluated according to the Portfolio’s social criteria.

The Portfolio may also invest without limitation in fixed income securities of all types and without regard to duration or investment ratings. Fixed income investments may include corporate debt, including high yield or “junk bonds,” structured notes, asset backed securities and similar synthetic securities, U.S. treasuries and short-term money market instruments or other cash equivalents.

The Portfolio is permitted to invest in securities issued by companies domiciled anywhere in the world and denominated in any currency, without limitation. The Portfolio may also invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues. Additionally, in seeking to achieve its objective, the Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards.

The Portfolio is classified as a non-diversified fund, which means that the Portfolio is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as diversified.

The Portfolio is not authorized or sponsored by the Roman Catholic Church or the USCCB.

<b>Principal Investment Risks</b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Non-diversification Risk.    A non-diversified fund, such as the Portfolio, is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if it were classified as diversified. As a non-diversified fund, the Portfolio’s performance may be more vulnerable to changes in the market value of a single position and risks associated with a single economic, political or regulatory occurrence than a diversified fund.

• Multi-Manager Risk.    The Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the broad range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Investment in Other Investment Companies Risk –  To the extent that the Portfolio acquires securities issued by other investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies. Securities issued by other investment companies, including ETFs, are also equity securities and, as such, are subject to Market Risk and Management Risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively do so.

• Socially Responsible Investing Risk.    The Portfolio considers the Social Guidelines in its investment process and may choose not to purchase, or may sell, otherwise profitable investments in companies which have been identified as being in conflict with the Social Guidelines. This means that the Portfolio may underperform other similar funds that do not consider the Social Guidelines when making investment decisions.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities. Additionally, risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time. The Portfolio generally considers “emerging markets” countries to be those included in the MSCI Emerging Markets Index

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income.

• Extension Risk – Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Asset-Backed/Mortgage-Backed Securities Risk –  The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Risks Associated with Investments in Futures.    The Portfolio is permitted to invest in futures. Investment in futures depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Futures involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks.
  
  The value of futures may rise or fall more rapidly than other investments and there is a risk that the Portfolio may lose more than the original amount invested in futures. Futures also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances. Compared to other types of investments, futures may be harder to value and may also be less tax efficient. To the extent that the Portfolio uses futures to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the futures instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of futures may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Thinly traded Securities.    The Portfolio may invest in securities, including privately placed and structured securities and derivatives, for which there may be limited markets/thinly traded issues. Investment in these securities involve the following risks:

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Valuation Risk – When market quotations are not readily available or are deemed to be unreliable, the Portfolio values its investments at fair value as determined in good faith pursuant to policies and procedures approved by the Board of Trustees. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets, or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in Total Annual Portfolio Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 17.01% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your costs would be:

<b>Principal Investment Strategies</b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective, which includes a combination of capital appreciation and income, by investing primarily in equity securities while retaining the flexibility to invest in fixed income securities. In addition to equity and fixed income securities, the Portfolio may invest in other instruments, including, but not limited to, derivatives. The Portfolio is permitted to invest in any equity security, which includes securities issued by other investment companies, including exchange traded funds (“ETFs”) and securities issued by one or more of the other portfolios of HC Capital Trust. The Portfolio may invest in companies of any market capitalization.

Further, under the supervision of the Adviser, the Portfolio integrates a range of social and moral concerns into its security selection process. These issues may include protecting human life; promoting human dignity; reducing arms production; pursuing economic justice; protecting the environment, and encouraging corporate responsibility. This will be accomplished with reference to the principles contained in the United States Conference of Catholic Bishops’ (“USCCB”) Socially Responsible Investing Guidelines (“Social Guidelines”). Potential investments for the Portfolio are selected for financial soundness and evaluated according to the Portfolio’s social criteria.

The Portfolio may also invest without limitation in fixed income securities of all types and without regard to duration or investment ratings. Fixed income investments may include corporate debt, including high yield or “junk bonds,” structured notes, asset backed securities and similar synthetic securities, U.S. treasuries and short-term money market instruments or other cash equivalents.

The Portfolio is permitted to invest in securities issued by companies domiciled anywhere in the world and denominated in any currency, without limitation. The Portfolio may also invest in securities, including privately placed and structured securities, for which there may be limited markets/thinly traded issues. Additionally, in seeking to achieve its objective, the Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards.

The Portfolio is classified as a non-diversified fund, which means that the Portfolio is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if the Portfolio were classified as diversified.

The Portfolio is not authorized or sponsored by the Roman Catholic Church or the USCCB.

<b>Principal Investment Risks</b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Non-diversification Risk.    A non-diversified fund, such as the Portfolio, is permitted to invest a greater portion of its assets in a limited number of issuers than would be the case if it were classified as diversified. As a non-diversified fund, the Portfolio’s performance may be more vulnerable to changes in the market value of a single position and risks associated with a single economic, political or regulatory occurrence than a diversified fund.

• Multi-Manager Risk.    The Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the broad range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Investment in Other Investment Companies Risk –  To the extent that the Portfolio acquires securities issued by other investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies. Securities issued by other investment companies, including ETFs, are also equity securities and, as such, are subject to Market Risk and Management Risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively do so.

• Socially Responsible Investing Risk.    The Portfolio considers the Social Guidelines in its investment process and may choose not to purchase, or may sell, otherwise profitable investments in companies which have been identified as being in conflict with the Social Guidelines. This means that the Portfolio may underperform other similar funds that do not consider the Social Guidelines when making investment decisions.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities. Additionally, risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time. The Portfolio generally considers “emerging markets” countries to be those included in the MSCI Emerging Markets Index

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of fixed income securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income.

• Extension Risk – Fixed income securities held by the Portfolio are subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Asset-Backed/Mortgage-Backed Securities Risk –  The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Risks Associated with Investments in Futures.    The Portfolio is permitted to invest in futures. Investment in futures depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Futures involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks.
  
  The value of futures may rise or fall more rapidly than other investments and there is a risk that the Portfolio may lose more than the original amount invested in futures. Futures also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances. Compared to other types of investments, futures may be harder to value and may also be less tax efficient. To the extent that the Portfolio uses futures to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the futures instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of futures may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Thinly traded Securities.    The Portfolio may invest in securities, including privately placed and structured securities and derivatives, for which there may be limited markets/thinly traded issues. Investment in these securities involve the following risks:

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Valuation Risk – When market quotations are not readily available or are deemed to be unreliable, the Portfolio values its investments at fair value as determined in good faith pursuant to policies and procedures approved by the Board of Trustees. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets, or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

HC Strategic Shares | The International Equity Portfolio

<b>The International Equity Portfolio</b>

<b>Investment Objective</b>

The investment objective of The International Equity Portfolio is to maximize total return.

<b>Fees and Expenses</b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The International Equity Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The International Equity Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.34%
Other Expenses	0.09%
Total Annual Portfolio Operating Expenses	0.43%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The International Equity Portfolio HC Strategic Shares USD ($)
1 Year	$ 44
3 Years	138
5 Years	241
10 Years	$ 542

<b>Portfolio Turnover</b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 29.94% of the average value of its portfolio.

<b>Principal Investment Strategies</b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Under normal circumstances, the Portfolio will provide exposure to investments that are economically tied to at least three different countries, including the U.S., and at least 40% of the Portfolio’s net assets will provide exposure to investments that are economically tied to non-U.S. countries. Although the Portfolio, a diversified investment company, may invest anywhere in the world, the Portfolio is expected to invest primarily in the equity markets included in the MSCI EAFE Index. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of issuers located in non-U.S. countries. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in foreign currencies and to hedge against fluctuations in the relative value of the currencies in which securities held by the Portfolio are denominated. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index. The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks</b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

The table accompanying the bar chart compares the Portfolio’s performance over time on a before and after-tax basis to that of a broad based market index. Of course, past performance, before and after taxes, does not indicate how the Portfolio will perform in the future.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 29.94% of the average value of its portfolio.

Strategy [Heading]

<b>Principal Investment Strategies</b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Under normal circumstances, the Portfolio will provide exposure to investments that are economically tied to at least three different countries, including the U.S., and at least 40% of the Portfolio’s net assets will provide exposure to investments that are economically tied to non-U.S. countries. Although the Portfolio, a diversified investment company, may invest anywhere in the world, the Portfolio is expected to invest primarily in the equity markets included in the MSCI EAFE Index. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of issuers located in non-U.S. countries. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in foreign currencies and to hedge against fluctuations in the relative value of the currencies in which securities held by the Portfolio are denominated. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index. The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

Risk [Heading]

<b>Principal Investment Risks</b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Portfolio Turnover</b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 40.38% of the average value of its portfolio.

<b>Principal Investment Strategies</b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Under normal circumstances, the Portfolio will provide exposure to investments that are economically tied to at least three different countries, including the U.S., and at least 40% of the Portfolio’s net assets will provide exposure to investments that are economically tied to non-U.S. countries.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 40.38% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

<b>Principal Investment Strategies</b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in equity securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Under normal circumstances, the Portfolio will provide exposure to investments that are economically tied to at least three different countries, including the U.S., and at least 40% of the Portfolio’s net assets will provide exposure to investments that are economically tied to non-U.S. countries. Although the Portfolio, a diversified investment company, may invest anywhere in the world, the Portfolio is expected to invest primarily in the equity markets included in the MSCI EAFE Index. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in equity securities of issuers located in non-U.S. countries. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. The Portfolio may also use currency forwards in connection with the purchase and sale of securities denominated in a foreign currency and to hedge against fluctuations in the relative value of the currencies in which securities held by the Portfolio are denominated. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks</b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The Emerging Markets Portfolio

<b>The Emerging Markets Portfolio</b>

<b>Investment Objective </b>

The investment objective of The Emerging Markets Portfolio is to provide maximum total return, primarily through capital appreciation.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Emerging Markets Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Emerging Markets Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.49%
Other Expenses	0.17%
Acquired Fund Fees and Expenses	0.02%
Total Annual Portfolio Operating Expenses	0.68%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Emerging Markets Portfolio HC Strategic Shares USD ($)
1 Year	$ 69
3 Years	218
5 Years	379
10 Years	$ 847

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 54.90% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in securities of issuers domiciled or, in the view of the Specialist Manager, deemed to be doing material amounts of business in countries determined by the Specialist Manager to have a developing or emerging economy or securities market. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Typically 80% of the Portfolio’s net assets will be invested in equity securities, equity swaps, structured equity notes, equity linked notes and depositary receipts of issuers domiciled or, in the view of the Specialist Manager, deemed to be doing material amounts of business in emerging market countries. The Portfolio, a diversified investment company, invests primarily in the Morgan Stanley Capital International^® Emerging Markets Index (“MSCI EM Index”) countries. As the MSCI EM Index introduces new emerging market countries, the Portfolio may include those countries among the countries in which it may invest. In determining securities in which to invest, the Portfolio’s management team will evaluate the countries’ economic and political climates with prospects for sustained macro and micro economic growth. The Portfolio’s management team will take into account traditional securities valuation methods, including (but not limited to) an analysis of price in relation to assets, earnings, cash flows, projected earnings growth, inflation and interest rates. Liquidity and transaction costs will also be considered. The Portfolio may also invest in companies of any market capitalization. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in securities issued by companies domiciled or deemed to be doing material amounts of business in countries that have a developing or emerging economy or securities market. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• China Risk.    In addition to the risks listed above under “Emerging Market Securities,” investing in China presents additional risks including confiscatory taxation, nationalization, exchange control regulations (including currency blockage) and differing legal standards. The Chinese government could, at any time, alter or discontinue economic reform programs implemented since 1978. Chinese authorities may intervene in the China securities market and halt or suspend trading of securities for short or even longer periods of time. Recently, the China securities market has experienced considerable volatility and been subject to relatively frequent and extensive trading halts and suspensions. These trading halts and suspensions have, among other things, contributed to uncertainty in the markets and reduced the liquidity of the securities subject to such trading halts and suspensions, which could include securities held by a Portfolio.

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 54.90% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in securities of issuers domiciled or, in the view of the Specialist Manager, deemed to be doing material amounts of business in countries determined by the Specialist Manager to have a developing or emerging economy or securities market. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Typically 80% of the Portfolio’s net assets will be invested in equity securities, equity swaps, structured equity notes, equity linked notes and depositary receipts of issuers domiciled or, in the view of the Specialist Manager, deemed to be doing material amounts of business in emerging market countries. The Portfolio, a diversified investment company, invests primarily in the Morgan Stanley Capital International^® Emerging Markets Index (“MSCI EM Index”) countries. As the MSCI EM Index introduces new emerging market countries, the Portfolio may include those countries among the countries in which it may invest. In determining securities in which to invest, the Portfolio’s management team will evaluate the countries’ economic and political climates with prospects for sustained macro and micro economic growth. The Portfolio’s management team will take into account traditional securities valuation methods, including (but not limited to) an analysis of price in relation to assets, earnings, cash flows, projected earnings growth, inflation and interest rates. Liquidity and transaction costs will also be considered. The Portfolio may also invest in companies of any market capitalization. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in securities issued by companies domiciled or deemed to be doing material amounts of business in countries that have a developing or emerging economy or securities market. Also, consistent with their respective investment styles, the Portfolio’s Specialist Managers may use instruments such as option or futures contracts in order to gain market exposure pending investment or to hedge against fluctuations in market price of the securities in which the Portfolio invests. In accordance with applicable interpretations of the SEC, certain derivative instruments may be counted as equity securities for purposes of the Portfolio’s policies regarding investments in equity securities, to the extent that such derivative instruments have economic characteristics similar to those of equity securities.

Additionally, a portion of the Portfolio may be managed using a “passive” investment approach designed to approximate as closely as practicable, before expenses, the performance of either the Portfolio’s benchmark index or, from time to time, one or more identifiable subsets or other portions of that index.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

Risk [Heading]

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• Passive Investing Risk – a portion of the Portfolio employs a passive investment approach, which attempts to approximate as closely as practicable, before expenses, the performance of one or more different segments of the Portfolio’s investment universe, as deemed appropriate by the Adviser, regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Portfolio’s return to be lower than if the Portfolio employed an active strategy. In addition, the Portfolio’s return may not match or achieve a high degree of correlation with the return of the target investment pool due to operating expenses, transaction costs, and cash flows.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Equity Risks.    Investment in equity securities involves the following risks:

• Equity Market Risk – The market value of an equity security and the equity markets in general can be volatile.

• Small/Mid Cap Risk – Small and mid-cap companies may be more vulnerable to adverse business or economic developments than larger capitalization companies. Securities issued by these companies may be less liquid and/or more volatile than securities of larger companies or the overall securities markets. Small and mid-cap companies may be adversely affected during periods when investors prefer to hold securities of large capitalization companies.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• China Risk.    In addition to the risks listed above under “Emerging Market Securities,” investing in China presents additional risks including confiscatory taxation, nationalization, exchange control regulations (including currency blockage) and differing legal standards. The Chinese government could, at any time, alter or discontinue economic reform programs implemented since 1978. Chinese authorities may intervene in the China securities market and halt or suspend trading of securities for short or even longer periods of time. Recently, the China securities market has experienced considerable volatility and been subject to relatively frequent and extensive trading halts and suspensions. These trading halts and suspensions have, among other things, contributed to uncertainty in the markets and reduced the liquidity of the securities subject to such trading halts and suspensions, which could include securities held by a Portfolio.

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The Core Fixed Income Portfolio

<b>The Core Fixed Income Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Core Fixed Income Portfolio is to provide a high level of current income consistent with the preservation of capital.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Core Fixed Income Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Core Fixed Income Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.15%
Other Expenses	0.21%
Acquired Fund Fees and Expenses	0.01%
Total Annual Portfolio Operating Expenses	0.37%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes the reinvestment of all dividends and distributions in shares of the Portfolio and that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Core Fixed Income Portfolio HC Strategic Shares USD ($)
1 Year	$ 38
3 Years	119
5 Years	208
10 Years	$ 468

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 43.79% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in fixed income securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio, under normal circumstances, invests predominantly in fixed income securities that, at the time of purchase, are rated in one of four highest rating categories assigned by one of the major independent rating agencies (“Baa” or higher by Moodys, “BBB” or higher by Standard & Poor’s) or are, in the view of the Specialist Manager, deemed to be of comparable quality. Securities in the fourth highest rating category may have speculative characteristics. From time to time, a substantial portion of the Portfolio, a diversified investment company, may be invested in any of the following: (1) investment grade mortgage-backed or asset-backed securities; (2) securities issued or fully guaranteed by the U.S. Government, Federal Agencies, or sponsored agencies; (3) investment grade fixed income securities issued by U.S. corporations; or (4) municipal bonds (i.e., debt securities issued by municipalities and related entities). Under normal conditions, the Portfolio may invest up to 20% of its assets in high yield securities (“junk bonds”) as well as cash or money market instruments in order to maintain liquidity, or in the event that the Specialist Manager determines that securities meeting the Portfolio’s investment objective and policies are not otherwise readily available for purchase. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in fixed income securities. Consistent with its investment policies, the Portfolio may purchase and sell securities without regard to the effect on portfolio turnover. Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Aggregate Bond Index, which range, as of June 30, 2018, was between 1 and 29 years. The weighted average maturity of the Bloomberg Barclays U.S. Aggregate Bond Index as of June 30, 2018 was 12.9 years. The Portfolio may engage in transactions involving instruments such as option or futures contracts, both in order to hedge against fluctuations in the market value of the securities in which the Portfolio invests and to achieve market exposure pending investment and, in the case of asset-backed and similar securities, for investment purposes.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• High Turnover Risk – High portfolio turnover will cause the Portfolio to incur additional transaction costs; higher transaction costs will reduce total return. High portfolio turnover also is likely to generate short-term capital gains, which, once distributed, is taxed to the shareholder as ordinary income and does not retain its character as short-term capital gain in the hands of a shareholder.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Portfolio dividends derived from certain “private activity” municipal securities generally will constitute an item of tax preference includable in alternative minimum taxable income for both corporate and non-corporate taxpayers.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of its net assets) in fixed income securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio, under normal circumstances, invests predominantly in fixed income securities that, at the time of purchase, are rated in one of four highest rating categories assigned by one of the major independent rating agencies (“Baa” or higher by Moodys, “BBB” or higher by Standard & Poor’s) or are, in the view of the Specialist Manager, deemed to be of comparable quality. Securities in the fourth highest rating category may have speculative characteristics. From time to time, a substantial portion of the Portfolio, a diversified investment company, may be invested in any of the following: (1) investment grade mortgage-backed or asset-backed securities; (2) securities issued or fully guaranteed by the U.S. Government, Federal Agencies, or sponsored agencies; (3) investment grade fixed income securities issued by U.S. corporations; or (4) municipal bonds (i.e., debt securities issued by municipalities and related entities). Under normal conditions, the Portfolio may invest up to 20% of its assets in high yield securities (“junk bonds”) as well as cash or money market instruments in order to maintain liquidity, or in the event that the Specialist Manager determines that securities meeting the Portfolio’s investment objective and policies are not otherwise readily available for purchase. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in fixed income securities. Consistent with its investment policies, the Portfolio may purchase and sell securities without regard to the effect on portfolio turnover. Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Aggregate Bond Index, which range, as of June 30, 2018, was between 1 and 29 years. The weighted average maturity of the Bloomberg Barclays U.S. Aggregate Bond Index as of June 30, 2018 was 12.9 years. The Portfolio may engage in transactions involving instruments such as option or futures contracts, both in order to hedge against fluctuations in the market value of the securities in which the Portfolio invests and to achieve market exposure pending investment and, in the case of asset-backed and similar securities, for investment purposes.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

• High Turnover Risk – High portfolio turnover will cause the Portfolio to incur additional transaction costs; higher transaction costs will reduce total return. High portfolio turnover also is likely to generate short-term capital gains, which, once distributed, is taxed to the shareholder as ordinary income and does not retain its character as short-term capital gain in the hands of a shareholder.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities. Portfolio dividends derived from certain “private activity” municipal securities generally will constitute an item of tax preference includable in alternative minimum taxable income for both corporate and non-corporate taxpayers.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

HC Strategic Shares | The Fixed Income Opportunity Portfolio

<b>The Fixed Income Opportunity Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Fixed Income Opportunity Portfolio is to achieve above-average total return by investing in high yield securities commonly referred to as “junk bonds.”

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Fixed Income Opportunity Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The Fixed Income Opportunity Portfolio HC Strategic Shares
Management Fees (based on asset allocations among Specialist Managers, see “Advisory Services – Specialist Managers”)	0.38%
Other Expenses	0.08%
Acquired Fund Fees and Expenses	0.04%
Total Annual Portfolio Operating Expenses	0.50%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes the reinvestment of all dividends and distributions in shares of the Portfolio and that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Fixed Income Opportunity Portfolio HC Strategic Shares USD ($)
1 Year	$ 51
3 Years	160
5 Years	280
10 Years	$ 628

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 37.57% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of net assets) in fixed income securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. A principal investment strategy of the Portfolio is to invest in high yield securities including “junk bonds.” Under normal circumstances, at least 50% of the Portfolio’s total assets will be invested in junk bonds. These securities are fixed income securities that are rated below the fourth highest category assigned by one of the major independent rating agencies or are, in the view of the Specialist Manager, deemed to be of comparable quality. Such securities may include: corporate bonds, collateralized loan obligations (CLOs), collateralized bond obligations (CBOs) and collateralized debt obligations (CDOs) (CDO investments are expected to be limited to less than 15% of the Portfolio), agency and non-agency mortgage-backed securities, collateralized mortgage obligations, commercial mortgage-backed securities and asset-backed securities, REITs, foreign fixed income securities, including emerging market debt, convertible bonds, preferred stocks, treasury inflation bonds, loan participations, swaps and fixed and floating rate loans. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in fixed income securities.

The Portfolio may invest in U.S. government securities, including but not limited to treasuries, agencies and commercial paper. The Portfolio may also hold a portion of its assets in cash or money market instruments in order to maintain liquidity or in the event that the Specialist Manager determines that securities meeting the Portfolio’s investment objective and policies are not otherwise readily available for purchase.

Consistent with its investment policies, the Portfolio may purchase and sell high yield securities. Purchases and sales of securities may be effected without regard to the effect on portfolio turnover. Securities purchased for the Portfolio will have varying maturities, but, under normal circumstances, the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. High Yield Ba/B 2% Issuer Capped Index, which range, as of June 30, 2018, was between 1 and 13 years. The Portfolio may engage in transactions involving instruments such as option or futures contracts, both in order to hedge against fluctuations in the market value of the securities in which the Portfolio invests and to achieve market exposure pending investment.

The performance benchmark for this Portfolio is the Bloomberg Barclays U.S. High Yield Ba/B 2% Issuer Capped Index, an unmanaged index of high yield securities that is widely recognized as an indicator of the performance of such securities. The Specialist Managers actively manage the interest rate risk of the Portfolio relative to this benchmark.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Floating Rate Loans Risk – The risks associated with floating rate loans are similar to the risks of below investment grade securities. Changes in economic conditions are likely to cause issuers of these securities to be unable to meet their obligations. In addition, the value of the collateral securing the loan may decline, causing a loan to be substantially unsecured. The sale and purchase of a bank loan are subject to the requirements of the underlying credit agreement governing such bank loan. These requirements may limit the eligible pool of potential bank loan holders by placing conditions or restrictions on sales and purchases of bank loans. Further, bank loans are not traded on an exchange and purchasers and sellers of bank loans rely on market makers, usually the administrative agent for a particular bank loan, to trade bank loans. These factors, in addition to overall market volatility, may negatively impact the liquidity of loans. Difficulty in selling a floating rate loan may result in a loss. Borrowers may pay back principal before the scheduled due date when interest rates decline, which may require the Portfolio to replace a particular loan with a lower-yielding security. There may be less extensive public information available with respect to loans than for rated, registered or exchange listed securities. The Portfolio may assume the credit risk of the primary lender in addition to the borrower, and investments in loan assignments may involve the risks of being a lender.

• Loan Participation Risk – Loan participations typically will result in a Portfolio having a contractual relationship only with the lender, not with the borrower. In connection with purchasing loan participations, a Portfolio generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and a Portfolio may not benefit directly from any collateral supporting the loan in which it has purchased the participation. As a result, a Portfolio will assume the credit risk of both the borrower and the lender that is selling the participation. A Portfolio may have difficulty disposing of loan participations as the market for such instruments is not highly liquid.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments, including option and futures contracts, may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

• Other Risks

• REIT Risk – REIT prices may fall because of the failure of borrowers to pay their loans and/or poor management. The value of REITs may also be affected by increases in property taxes and changes in tax laws and interest rates.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio invests primarily (i.e., at least 80% of net assets) in fixed income securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. A principal investment strategy of the Portfolio is to invest in high yield securities including “junk bonds.” Under normal circumstances, at least 50% of the Portfolio’s total assets will be invested in junk bonds. These securities are fixed income securities that are rated below the fourth highest category assigned by one of the major independent rating agencies or are, in the view of the Specialist Manager, deemed to be of comparable quality. Such securities may include: corporate bonds, collateralized loan obligations (CLOs), collateralized bond obligations (CBOs) and collateralized debt obligations (CDOs) (CDO investments are expected to be limited to less than 15% of the Portfolio), agency and non-agency mortgage-backed securities, collateralized mortgage obligations, commercial mortgage-backed securities and asset-backed securities, REITs, foreign fixed income securities, including emerging market debt, convertible bonds, preferred stocks, treasury inflation bonds, loan participations, swaps and fixed and floating rate loans. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in fixed income securities.

The Portfolio may invest in U.S. government securities, including but not limited to treasuries, agencies and commercial paper. The Portfolio may also hold a portion of its assets in cash or money market instruments in order to maintain liquidity or in the event that the Specialist Manager determines that securities meeting the Portfolio’s investment objective and policies are not otherwise readily available for purchase.

Consistent with its investment policies, the Portfolio may purchase and sell high yield securities. Purchases and sales of securities may be effected without regard to the effect on portfolio turnover. Securities purchased for the Portfolio will have varying maturities, but, under normal circumstances, the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. High Yield Ba/B 2% Issuer Capped Index, which range, as of June 30, 2018, was between 1 and 13 years. The Portfolio may engage in transactions involving instruments such as option or futures contracts, both in order to hedge against fluctuations in the market value of the securities in which the Portfolio invests and to achieve market exposure pending investment.

The performance benchmark for this Portfolio is the Bloomberg Barclays U.S. High Yield Ba/B 2% Issuer Capped Index, an unmanaged index of high yield securities that is widely recognized as an indicator of the performance of such securities. The Specialist Managers actively manage the interest rate risk of the Portfolio relative to this benchmark.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Floating Rate Loans Risk – The risks associated with floating rate loans are similar to the risks of below investment grade securities. Changes in economic conditions are likely to cause issuers of these securities to be unable to meet their obligations. In addition, the value of the collateral securing the loan may decline, causing a loan to be substantially unsecured. The sale and purchase of a bank loan are subject to the requirements of the underlying credit agreement governing such bank loan. These requirements may limit the eligible pool of potential bank loan holders by placing conditions or restrictions on sales and purchases of bank loans. Further, bank loans are not traded on an exchange and purchasers and sellers of bank loans rely on market makers, usually the administrative agent for a particular bank loan, to trade bank loans. These factors, in addition to overall market volatility, may negatively impact the liquidity of loans. Difficulty in selling a floating rate loan may result in a loss. Borrowers may pay back principal before the scheduled due date when interest rates decline, which may require the Portfolio to replace a particular loan with a lower-yielding security. There may be less extensive public information available with respect to loans than for rated, registered or exchange listed securities. The Portfolio may assume the credit risk of the primary lender in addition to the borrower, and investments in loan assignments may involve the risks of being a lender.

As a result, a Portfolio will assume the credit risk of both the borrower and the lender that is selling the participation. A Portfolio may have difficulty disposing of loan participations as the market for such instruments is not highly liquid.

The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. Prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health, although changes in market interest rates also will affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments, including option and futures contracts, may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the MSCI EAFE Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

HC Strategic Shares | The U.S. Government Fixed Income Securities Portfolio

<b>The U.S. Government Fixed Income Securities Portfolio </b>

<b>Investment Objective </b>

The investment objective of The U.S. Government Fixed Income Securities Portfolio is to provide a moderate and sustainable level of current income, consistent with the preservation of capital by investing in a diversified portfolio of primarily U.S. Treasury and government related fixed income securities.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees</b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The U.S. Government Fixed Income Securities Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses</b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The U.S. Government Fixed Income Securities Portfolio HC Strategic Shares
Management Fees	0.11%
Other Expenses	0.08%
Total Annual Portfolio Operating Expenses	0.19%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the HC Strategic Shares of the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The U.S. Government Fixed Income Securities Portfolio HC Strategic Shares USD ($)
1 Year	$ 19
3 Years	61
5 Years	107
10 Years	$ 243

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 32.58% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in fixed income securities issued or fully guaranteed by the U.S. Government, Federal Agencies, or sponsored agencies. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. Securities in which the Portfolio may invest include bonds, notes and certificates of deposit. These may include securities issued by federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. Government. In general the portfolio will maintain aggregate characteristics similar to the Bloomberg Barclays U.S. Government Index. Securities held by the Portfolio will be rated investment grade or better by at least two rating agencies at the time of purchase if not rated by an agency, of comparable credit quality as determined by the Specialist Manager at the time of purchase. Overall credit quality of the Portfolio will be maintained at a level substantially equal to that of the Bloomberg Barclays U.S. Government Index. The Portfolio will attempt to be fully invested at all times in U.S. Government fixed income securities, but may hold cash positions at times to adjust the duration of the Portfolio to more closely approximate that of the Bloomberg Barclays U.S. Government Index, to replicate the interest rate sensitivity of the securities in the Bloomberg Barclays U.S. Government Index, or to approximate the exposure to cash in the Bloomberg Barclays U.S. Government Index from coupon payments, principal payments or called securities. The Portfolio intends to maintain an effective dollar weighted average portfolio maturity similar to that of the Bloomberg Barclays U.S. Government Index, which was 7.50 years as of June 30, 2018. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in U.S. fixed income securities issued or fully guaranteed by the U.S. Government, Federal Agencies, or sponsored agencies.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. This risk should be low for the Portfolio as it invests mainly in securities that are not callable.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Performance Bar Chart and Table<br/><br/>Performance.</b>

The chart and table below show how The U.S. Government Fixed Income Securities Portfolio has performed, and how its performance has varied, from year to year. The bar chart shows returns on a before-tax basis and gives some indication of risk by showing changes in the Portfolio’s yearly performance for each full calendar year since the Portfolio’s inception on December 6, 2010. The table accompanying the bar chart compares the Portfolio’s performance over time on a before and after-tax basis to that of a broad based market index. Of course, past performance, before and after taxes, does not indicate how the Portfolio will perform in the future.

<b>Year-by-Year Total Returns as of 12/31</b>

The Portfolio’s HC Strategic Shares before-tax return for the period from January 1, 2018 through September 30, 2018 (non-annualized) was -1.79%.

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 20.77% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of its net assets) in inflation-indexed bonds issued by the U.S. government and non-U.S. governments, their agencies and instrumentalities and corporations. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio may invest in non-investment grade securities (“junk bonds”). Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Treasury Inflation Protected Securities Index (“Barclays US TIPS Index”), which range, as of June 30, 2018, was between 1 and 29 years. The weighted average maturity of the Barclays US TIPS Index as of June 30, 2018 was 8.3 years. The Portfolio may invest in securities issued by foreign corporations. The Portfolio’s investments in non-U.S. governments and corporations may include securities issued in emerging markets countries.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Deflation Risk – Deflation risk is the possibility that prices throughout the economy decline over time – the opposite of inflation. If inflation is negative, the principal and income of an inflation-protected bond will decline and could result in losses.

• Inflation Indexed Bonds Risk – The principal value of an investment is not protected or otherwise guaranteed by virtue of the Portfolio’s investments in inflation-indexed bonds. Inflation-indexed bonds are fixed-income securities whose principal value is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.
  
  Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal value.
  
  The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates are tied to the relationship between nominal interest rates and the rate of inflation. If nominal interest rates increase at a faster rate than inflation, real interest rates may rise, leading to a decrease in value of inflation-indexed bonds. Short-term increases in inflation may lead to a decline in value. Inflation-indexed bonds issued by non-U.S. governments would be expected to be indexed to the inflation rates prevailing in those countries.

• Inflation Indexed Bonds Tax Risk – Any increase in the principal amount of an inflation-indexed security may be included for tax purposes in the Portfolio’s gross income, even though no cash attributable to such gross income has been received by the Portfolio. In such event, the Portfolio may be required to make annual distributions to shareholders that exceed the cash it has otherwise received. In order to pay such distributions, the Portfolio may be required to raise cash by selling portfolio investments. The sale of such investments could result in capital gains to the Portfolio and additional capital gain distributions to shareholders. In addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by the Portfolio may cause amounts previously distributed to shareholders in the taxable year as income to be characterized as a return of capital.

• Non-Investment-Grade Securities – Non-investment-grade securities, also referred to as “high-yield securities” or “junk bonds,” are debt securities that are rated lower than the four highest rating categories by a nationally recognized statistical rating organization (for example, lower than Baa3/P-2 by Moody’s Investors Service, Inc. (Moody’s) or below BBB–/A-2 by Standard & Poor’s) or are determined to be of comparable quality by the fund’s advisor. These securities are generally considered to be, on balance, predominantly speculative with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation, and they will generally involve more credit risk than securities in the investment-grade categories. Non-investment-grade securities generally provide greater income and opportunity for capital appreciation than higher quality securities, but they also typically entail greater price volatility and principal and income risk.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Emerging Markets Risk – Risks associated with foreign investments may be intensified in the case of investments in emerging market countries, whose political, legal and economic systems are less developed and less stable than those of more developed nations. Such investments are often less liquid and/or more volatile than securities issued by companies located in developed nations, such as the United States, Canada and those included in the Morgan Stanley Capital International Europe, Australasia and Far East (“MSCI EAFE”) Index. Certain types of securities, including emerging market securities, are subject to the risk that the securities may not be sold at the quoted market price within a reasonable period of time.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The U.S. Corporate Fixed Income Securities Portfolio

<b>The U.S. Corporate Fixed Income Securities Portfolio</b>

<b>Investment Objective </b>

The investment objective of The U.S. Corporate Fixed Income Securities Portfolio is to provide a moderate and sustainable level of current income, consistent with the preservation of capital by investing primarily in a diversified portfolio of investment grade fixed income securities issued by U.S. corporations.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The U.S. Corporate Fixed Income Securities Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The U.S. Corporate Fixed Income Securities Portfolio HC Strategic Shares
Management Fees	0.13%
Other Expenses	0.08%
Acquired Fund Fees and Expenses	0.02%
Total Annual Portfolio Operating Expenses	0.23%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the HC Strategic Shares of the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The U.S. Corporate Fixed Income Securities Portfolio HC Strategic Shares USD ($)
1 Year	$ 24
3 Years	74
5 Years	130
10 Years	$ 293

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 44.69% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e. at least 80% of net assets) in fixed income securities issued by U.S. corporations. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. In general, the Portfolio invests predominantly in investment grade fixed income securities and will maintain aggregate characteristics similar to the Bloomberg Barclays U.S. Corporate Index. Securities held by the Portfolio will be rated investment-grade or better by one of the established rating agencies or, if not rated by an agency, of comparable credit quality as determined by the Specialist Manager at the time of purchase. Securities held by the Portfolio which are downgraded below investment-grade by all ratings agencies may be retained up to a maximum market value of 5% of the Portfolio. Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Corporate Investment Grade Index, which range, as of June 30, 2018, was between 1 and 29 years. The weighted average maturity of the Bloomberg Barclays U.S. Corporate Investment Grade Index as of June 30, 2018 was 10.80 years. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in investment grade fixed income securities issued by U.S. corporations. The Portfolio may also invest up to 20% of its assets in municipal bonds (i.e., debt securities issued by municipalities and related entities). The Portfolio may invest in fixed income securities of foreign issuers.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Multi-Manager Risk – the Portfolio’s multi-manager structure involves the risk that the Specialist Managers serving the Portfolio do not achieve favorable investment results relative to other investments or that the Portfolio’s assets are not effectively allocated among Specialist Managers in a manner that enhances the Portfolio’s total return or reduces the volatility that might be expected of any one management style. Additionally, the multi-manager structure may, under certain circumstances, cause the Portfolio to incur higher trading costs than might occur in a fund served by a single investment adviser.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e. at least 80% of net assets) in fixed income securities issued by U.S. corporations. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. In general, the Portfolio invests predominantly in investment grade fixed income securities and will maintain aggregate characteristics similar to the Bloomberg Barclays U.S. Corporate Index. Securities held by the Portfolio will be rated investment-grade or better by one of the established rating agencies or, if not rated by an agency, of comparable credit quality as determined by the Specialist Manager at the time of purchase. Securities held by the Portfolio which are downgraded below investment-grade by all ratings agencies may be retained up to a maximum market value of 5% of the Portfolio. Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Corporate Investment Grade Index, which range, as of June 30, 2018, was between 1 and 29 years. The weighted average maturity of the Bloomberg Barclays U.S. Corporate Investment Grade Index as of June 30, 2018 was 10.80 years. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in investment grade fixed income securities issued by U.S. corporations. The Portfolio may also invest up to 20% of its assets in municipal bonds (i.e., debt securities issued by municipalities and related entities).

HC Strategic Shares | The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio

<b>The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio</b>

<b>Investment Objective </b>

The investment objective of The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio is to seek to provide a moderate and sustainable level of current income, consistent with the preservation of capital by investing primarily in a diversified portfolio of publicly issued mortgage and asset backed securities.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio HC Strategic Shares
Maximum Sales Charges	none
Maximum Redemption Fee	none

<b>Annual Operating Expenses </b><br/>(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	HC Strategic Shares The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio HC Strategic Shares
Management Fees	0.11%
Other Expenses	0.12%
Acquired Fund Fees and Expenses	0.03%
Total Annual Portfolio Operating Expenses	0.26%

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the HC Strategic Shares of the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The U.S. Mortgage/Asset Backed Fixed Income Securities Portfolio HC Strategic Shares USD ($)
1 Year	$ 27
3 Years	84
5 Years	146
10 Years	$ 331

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 17.13% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e. at least 80% of net assets) in U.S. mortgage and asset backed securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio invests predominantly in publicly issued, investment grade U.S. mortgage and asset backed securities and, in general, seeks to maintain aggregate characteristics similar to the Bloomberg Barclays U.S. Securitized Index. The Portfolio will seek to invest in U.S. dollar denominated agency and non-agency mortgage-backed securities backed by loans secured by residential, multifamily and commercial properties including, but not limited to: pass throughs, collateralized mortgage obligations (“CMOs”), real estate mortgage investment conduits (“REMICs”), stripped mortgage-backed securities (“SMBS”), project loans, construction loans, and adjustable rate mortgages. Income from MBS, ABS, CMO, REMIC and SMBS investments of the Portfolio will be taxed as ordinary income when distributed to shareholders unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in mortgage and asset backed securities. The Portfolio may also invest in U.S. Treasury and agency securities. Securities must be rated investment-grade or better by a nationally recognized credit rating agency at the time of purchase or, if not rated by an agency, of comparable credit quality as determined by the Specialist Manager at the time of purchase. The Portfolio may engage in transactions involving instruments such as option or futures contracts, both in order to hedge against fluctuations in the market value of the securities in which the Portfolio invests and to achieve market exposure pending investment and, in the case of asset-backed and similar securities, for investment purposes. Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Securitized Index, which has a weighted average maturity of 7.2 years as of June 30, 2018 and can vary between 1 and 9 years.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Asset-Backed/Mortgage-Backed Security Risk – The market value and yield of asset-backed and mortgage-backed securities can vary due to market interest rate fluctuations and early prepayments of underlying instruments. Although these securities may offer yields higher than those available from other types of securities, these securities may be less effective than other types of securities as a means of “locking in” attractive long-term rates because of the prepayment feature. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid. Mortgage-backed securities may be particularly susceptible to Prepayment Risk.

• Call/Prepayment Risk – When interest rates are declining, issuers of securities held by the Portfolio may prepay principal earlier than scheduled. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. Mortgage-backed and asset-backed securities are especially sensitive to prepayment.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

• Foreign Investment Risk.    Investment in foreign securities involves the following risks:

• Foreign Securities Risk – Investments in securities issued by non-U.S. companies and/or non-U.S. governments and their agencies, may be adversely affected by the lack of timely or reliable financial information, political, social and/or economic developments abroad and differences between U.S. and foreign regulatory requirements and market practices. Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar and transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Foreign Currency Risk – Securities denominated in foreign currencies are subject to the risk that the value of the foreign currency will decline in relation to the U.S. dollar. Currency exchange rates can be volatile and can be affected by, among other factors, the general economics of a country, or the actions of the U.S. or foreign governments or central banks. In addition, transaction expenses related to foreign securities, including custody fees, are generally more costly than transaction expenses for domestic securities.

• Risks Associated with Investments in Derivatives.    The Portfolio is permitted to invest in derivative instruments, including options, futures and options on futures, swaps, structured notes and currency forwards. Investment in derivatives depends largely on the performance of an underlying reference instrument or rate and the Specialist Manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates and/or other economic factors. Derivatives involve additional costs and often have risks similar to an investment in the reference instrument in addition to other risks, such as:

• General Derivative Risks – The value of derivative instruments may rise or fall more rapidly than other investments, and there is a risk that the Portfolio may lose more than the original amount invested in the derivative instrument. Derivative instruments also involve the risk that other parties to the derivative contract may fail to meet their obligations, which could cause losses to the Portfolio.

• Counterparty Risk – The Portfolio will be subject to counterparty credit risk with respect to derivative contracts entered into by the Portfolio or held by special purpose or structured vehicles in which the Portfolio invests, including other investment companies. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Portfolio may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Portfolio may obtain only a limited recovery or may obtain no recovery in such circumstances.

• Derivatives Tax Risk – Compared to other types of investments, derivatives may be harder to value and may also be less tax efficient. In addition, changes in government regulation of derivative instruments could affect the character, timing and amount of the Portfolio’s taxable income or gains, and may limit or prevent the Portfolio from using certain types of derivative instruments as a part of its investment strategy, which could make the investment strategy more costly to implement or require the Portfolio to change its investment strategy. To the extent that the Portfolio uses derivatives for hedging or to gain or limit exposure to a particular market or market segment, there may be imperfect correlation between the value of the derivative instrument and the value of the instrument being hedged or the relevant market or market segment, in which case the Portfolio may not realize the intended benefits. The Portfolio’s use of derivatives may be limited by the requirements for taxation of the Portfolio as a regulated investment company.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

Strategy [Heading]

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e. at least 80% of net assets) in U.S. mortgage and asset backed securities. In the unlikely event that a change in this investment policy is adopted by the Board of Trustees, shareholders will receive at least 60 days prior written notice before such change is implemented. The Portfolio invests predominantly in publicly issued, investment grade U.S. mortgage and asset backed securities and, in general, seeks to maintain aggregate characteristics similar to the Bloomberg Barclays U.S. Securitized Index. The Portfolio will seek to invest in U.S. dollar denominated agency and non-agency mortgage-backed securities backed by loans secured by residential, multifamily and commercial properties including, but not limited to: pass throughs, collateralized mortgage obligations (“CMOs”), real estate mortgage investment conduits (“REMICs”), stripped mortgage-backed securities (“SMBS”), project loans, construction loans, and adjustable rate mortgages. Income from MBS, ABS, CMO, REMIC and SMBS investments of the Portfolio will be taxed as ordinary income when distributed to shareholders unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in mortgage and asset backed securities. The Portfolio may also invest in U.S. Treasury and agency securities. Securities must be rated investment-grade or better by a nationally recognized credit rating agency at the time of purchase or, if not rated by an agency, of comparable credit quality as determined by the Specialist Manager at the time of purchase. The Portfolio may engage in transactions involving instruments such as option or futures contracts, both in order to hedge against fluctuations in the market value of the securities in which the Portfolio invests and to achieve market exposure pending investment and, in the case of asset-backed and similar securities, for investment purposes. Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays U.S. Securitized Index, which has a weighted average maturity of 7.2 years as of June 30, 2018 and can vary between 1 and 9 years.

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Short-Term Municipal Bond Portfolio HC Strategic Shares USD ($)
1 Year	$ 36
3 Years	113
5 Years	197
10 Years	$ 443

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 18.84% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e. at least 80% of net assets) in municipal bonds. The policy stated in the foregoing sentence is a fundamental policy and may not be changed without shareholder approval. Municipal bonds are debt securities issued by municipalities and related entities, the interest on which is exempt from Federal income tax so that they will qualify to pay “exempt-interest dividends” (“Municipal Securities”). The Portfolio intends to maintain a dollar-weighted effective average portfolio maturity of no longer than three years. The Portfolio invests primarily in securities that are rated in one of the top four rating categories of a nationally recognized statistical rating organization (“Baa” or higher by Moodys, “BBB” or higher by Standard & Poor’s) or, if unrated, that are determined by the Specialist Manager to be of comparable quality. Fixed income securities rated in the fourth highest rating category by a rating agency may have speculative characteristics. The Portfolio does not currently intend to invest in obligations, the interest on which is a preference item for purposes of the Federal alternative minimum tax. The Portfolio may invest in securities issued by other investment companies, including ETFs, that invest in municipal bonds.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Tax Risk – Changes in Federal tax laws or regulations could change the tax-exempt status of income from any or all of the Portfolio’s municipal securities. In addition, short-term capital gains and a portion of any gain attributable to bonds purchased at market discount will be treated as ordinary income for Federal tax purposes.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – Municipal securities held by the Portfolio may be called (prepaid) before their maturity dates. This usually occurs as interest rates are declining. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. In addition, the Portfolio may lose price appreciation if a bond it holds is called earlier than scheduled.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

HC Strategic Shares | The Intermediate Term Municipal Bond Portfolio

<b>The Intermediate Term Municipal Bond Portfolio </b>

<b>Investment Objective </b>

The investment objective of The Intermediate Term Municipal Bond Portfolio is to provide a high level of current income exempt from Federal income tax, consistent with the preservation of capital.

<b>Fees and Expenses </b>

The fee and expense tables below describe the fees and expenses that you may pay if you buy and hold HC Strategic Shares of the Portfolio.

<b>Shareholder Fees </b><br/>(fees paid directly from your investment)

Shareholder Fees	HC Strategic Shares The Intermediate Term Municipal Bond Portfolio HC Strategic Shares
Maximum Sales Charges	none

<b>Example</b>:

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes the reinvestment of all dividends and distributions in shares of the Portfolio, that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Expense Example	HC Strategic Shares The Intermediate Term Municipal Bond Portfolio HC Strategic Shares USD ($)
1 Year	$ 36
3 Years	113
5 Years	197
10 Years	$ 443

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 26.27% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of net assets) in municipal bonds. The policy stated in the foregoing sentence is a fundamental policy of the Portfolio and may not be changed without shareholder approval. Municipal bonds are debt securities issued by municipalities and related entities, the interest on which is exempt from Federal income tax so that they will qualify to pay “exempt-interest dividends” (“Municipal Securities”). Municipal Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, currently 2 to 20 years. Municipal Securities acquired for the Portfolio will generally be rated in one of the three highest rating categories assigned by one of the major independent rating agencies (“A” or higher by Moodys, or Standard & Poor’s), or are, in the view of the Specialist Manager, deemed to be of comparable quality. The Portfolio is, however, authorized to invest up to 15% of its assets in Municipal Securities that are rated in the fourth highest category and up to 10% of its assets in high yield securities (“junk bonds”). Fixed income securities rated in the fourth highest rating category by a rating agency may have speculative characteristics. The Portfolio is also authorized to invest in securities issued by other investment companies, such as ETFs and closed-end funds, that invest in Municipal Securities. Also, the Portfolio is authorized to invest up to 20% of its net assets in taxable instruments.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Tax Risk – Changes in Federal tax laws or regulations could change the tax-exempt status of income from any or all of the Portfolio’s municipal securities. In addition, short-term capital gains and a portion of any gain attributable to bonds purchased at market discount will be treated as ordinary income for Federal tax purposes.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – Municipal securities held by the Portfolio may be called (prepaid) before their maturity dates. This usually occurs as interest rates are declining. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. In addition, the Portfolio may lose price appreciation if a bond it holds is called earlier than scheduled.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. The prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health. Change in market interest rates will also affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

Strategy [Heading]

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of net assets) in municipal bonds. The policy stated in the foregoing sentence is a fundamental policy of the Portfolio and may not be changed without shareholder approval. Municipal bonds are debt securities issued by municipalities and related entities, the interest on which is exempt from Federal income tax so that they will qualify to pay “exempt-interest dividends” (“Municipal Securities”). Municipal Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, currently 2 to 20 years. Municipal Securities acquired for the Portfolio will generally be rated in one of the three highest rating categories assigned by one of the major independent rating agencies (“A” or higher by Moodys, or Standard & Poor’s), or are, in the view of the Specialist Manager, deemed to be of comparable quality. The Portfolio is, however, authorized to invest up to 15% of its assets in Municipal Securities that are rated in the fourth highest category and up to 10% of its assets in high yield securities (“junk bonds”). Fixed income securities rated in the fourth highest rating category by a rating agency may have speculative characteristics. The Portfolio is also authorized to invest in securities issued by other investment companies, such as ETFs and closed-end funds, that invest in Municipal Securities. Also, the Portfolio is authorized to invest up to 20% of its net assets in taxable instruments.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

Risk [Heading]

rr_RiskHeading

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Tax Risk – Changes in Federal tax laws or regulations could change the tax-exempt status of income from any or all of the Portfolio’s municipal securities. In addition, short-term capital gains and a portion of any gain attributable to bonds purchased at market discount will be treated as ordinary income for Federal tax purposes.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – Municipal securities held by the Portfolio may be called (prepaid) before their maturity dates. This usually occurs as interest rates are declining. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. In addition, the Portfolio may lose price appreciation if a bond it holds is called earlier than scheduled.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• High Yield Bond Risk – High yield bonds, commonly referred to as “junk bonds,” are considered speculative under traditional investment standards. The prices of these securities will rise and fall primarily in response to changes in the issuer’s financial health. Change in market interest rates will also affect prices. High yield bonds may also experience reduced liquidity, and sudden and substantial decreases in price, during certain market conditions.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

<b>Portfolio Turnover </b>

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 21.56% of the average value of its portfolio.

<b>Principal Investment Strategies </b>

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of net assets) in municipal bonds. The policy stated in the foregoing sentence is a fundamental policy of the Portfolio and may not be changed without shareholder approval. Municipal bonds are debt securities issued by municipalities and related entities, the interest on which is exempt from Federal income tax, and include general obligation bonds and notes, revenue bonds and notes (including industrial revenue bonds and municipal lease obligations), as well as participation interests relating to such securities and are referred to as “ Municipal Securities.” The Portfolio invests primarily in securities that are rated in one of the top four rating categories of a nationally recognized statistical rating organization (“Baa” or higher by Moodys, “BBB” or higher by Standard & Poor’s) or, if unrated, that are determined by the Specialist Manager to be of comparable quality. Municipal Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, currently 2 to 10 years. The Portfolio may invest in securities issued by other investment companies, including ETFs and closed-end funds, that invest in Municipal Securities.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

<b>Principal Investment Risks </b>

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Tax Risk – Changes in Federal tax laws or regulations could change the tax-exempt status of income from any or all of the Portfolio’s municipal securities. In addition, short-term capital gains and a portion of any gain attributable to bonds purchased at market discount will be treated as ordinary income for Federal tax purposes.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

• Revenue Bonds Risk – Payments of interest and principal are made only from the revenues generated by a particular facility, class of facilities or the proceeds of a special tax, or other revenue source, and depends on the money earned by that source.

• Private Activity Bonds Risk – Municipalities and other public authorities issue private activity bonds to finance development of industrial facilities for use by a private enterprise. The private enterprise pays the principal and interest on the bond, and the issuer does not pledge its faith, credit and taxing power for repayment. The Portfolio’s investments may consist of private activity bonds that may subject certain shareholders to an alternative minimum tax.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” investments in its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in the Total Annual Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s turnover was 21.56% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s Total Annual Operating Expenses remain the same. Although your actual cost may be higher or lower, based on these assumptions, your cost would be:

Strategy [Heading]

rr_StrategyHeading

<b>Principal Investment Strategies </b>

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Portfolio seeks to achieve its objective by investing primarily (i.e., at least 80% of net assets) in municipal bonds. The policy stated in the foregoing sentence is a fundamental policy of the Portfolio and may not be changed without shareholder approval. Municipal bonds are debt securities issued by municipalities and related entities, the interest on which is exempt from Federal income tax, and include general obligation bonds and notes, revenue bonds and notes (including industrial revenue bonds and municipal lease obligations), as well as participation interests relating to such securities and are referred to as “ Municipal Securities.” The Portfolio invests primarily in securities that are rated in one of the top four rating categories of a nationally recognized statistical rating organization (“Baa” or higher by Moodys, “BBB” or higher by Standard & Poor’s) or, if unrated, that are determined by the Specialist Manager to be of comparable quality. Municipal Securities purchased for the Portfolio will have varying maturities, but under normal circumstances the Portfolio will have an effective dollar weighted average portfolio maturity that is within the range of the average portfolio maturity in the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, currently 2 to 10 years. The Portfolio may invest in securities issued by other investment companies, including ETFs and closed-end funds, that invest in Municipal Securities.

The Portfolio is authorized to operate on a multi-manager basis. This means that a single Portfolio may be managed by more than one Specialist Manager. The multi-manager structure is generally designed to provide investors access to broadly diversified investment styles. The Trust seeks to engage skilled Specialist Managers to provide a broad exposure to the relevant asset class and returns in excess of the Portfolio’s benchmark over time.

Risk [Heading]

rr_RiskHeading

<b>Principal Investment Risks </b>

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investing in the Portfolio involves risks common to any investment in securities. There is no guarantee that the Portfolio will achieve its investment objective and, as is the case with any investment, you may lose money on your investment in the Portfolio. All mutual funds, including the Portfolio, are subject to Management Risk – the risk that the investment strategies employed in the investment selection process may not result in an increase in the value of your investment or in overall performance equal to other investments and Market Risk – the risk that the value of the securities held by a portfolio may decline in response to general market and economic conditions, or conditions that affect specific market sectors or individual companies.

There are also risks associated with the overall structure of the Portfolio. These include:

• Tax Risk – Changes in Federal tax laws or regulations could change the tax-exempt status of income from any or all of the Portfolio’s municipal securities. In addition, short-term capital gains and a portion of any gain attributable to bonds purchased at market discount will be treated as ordinary income for Federal tax purposes.

Additionally, the range of securities in which the Portfolio may invest, and the several investment strategies that may be used in seeking to achieve the Portfolio’s objective, involve additional risks. These are summarized below.

• Fixed Income Risk.    Investments in fixed income securities may involve the following risks, depending on the instrument involved:

• Credit Risk – An investment in the Portfolio also involves the risk that the issuer of a fixed income security that the Portfolio holds will fail to make timely payments of interest or principal, or go bankrupt, or that the value of the securities will decline because of a market perception that the issuer may not make payments on time, thus potentially reducing the Portfolio’s return. Changes in economic conditions are likely to cause issuers of these fixed income securities to be unable to meet their obligations. The lower the rating of a debt security, the higher its credit risk. In addition, the securities of many U.S. Government agencies, authorities or instrumentalities in which the Portfolio may invest are neither issued nor guaranteed by the U.S. Government, and may be supported only by the ability of the issuer to borrow from the U.S. Treasury or by the credit of the issuer.

• Interest Rate Risk – The value of fixed income securities held in the Portfolio, including U.S. Government securities, may decline with changes in interest rates. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. U.S. Government securities can exhibit price movements resulting from changes in interest rates. During low interest rate environments, the risk that interest rates will rise is increased. Such increases may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. These risks are greater when a low interest rate environment has existed for an extended period of time.

• Call/Prepayment Risk – Municipal Securities held by the Portfolio may be called (prepaid) before their maturity dates. This usually occurs as interest rates are declining. As a result of this risk, the Portfolio may have to reinvest these prepayments at those lower rates, thus reducing its income. In addition, the Portfolio may lose price appreciation if a bond it holds is called earlier than scheduled.

• Extension Risk – These securities are also subject to the risk that payment on the loans underlying the securities held by the Portfolio will be made more slowly when interest rates are rising. This could cause the market value of the securities to decline.

• Liquidity Risk – At times, certain securities may be difficult or impossible to sell at the price that would normally prevail in the market. The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Portfolio management or performance. This includes the risk of missing out on an investment opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Municipal Bond Risk – The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer’s regional economic conditions may affect the municipal security’s value, interest payments, repayment of principal and the Fund’s ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security’s value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

• Revenue Bonds Risk – Payments of interest and principal are made only from the revenues generated by a particular facility, class of facilities or the proceeds of a special tax, or other revenue source, and depends on the money earned by that source.

• Private Activity Bonds Risk – Municipalities and other public authorities issue private activity bonds to finance development of industrial facilities for use by a private enterprise. The private enterprise pays the principal and interest on the bond, and the issuer does not pledge its faith, credit and taxing power for repayment. The Portfolio’s investments may consist of private activity bonds that may subject certain shareholders to an alternative minimum tax.

• Exchange-Traded Funds Risk – An investment in securities issued by an ETF may be subject to the following risks: (1) shares of the ETF may trade at a discount to its net asset value; (2) an active trading market for the ETF’s shares may not develop; (3) the exchange on which the ETF is listed may, under certain circumstances, suspend trading of the ETF’s shares; and (4) to the extent that an ETF is acquired in order to track a specific asset or index, the ETF may fail to effectively accomplish that goal.

• Investment in Other Investment Companies Risk – As with other investments, investments in other investment companies are subject to market and selection risk. To the extent that the Portfolio acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Portfolio (including management and advisory fees) and, indirectly, the expenses of the acquired investment companies.

There is no guarantee that the Portfolio will meet its goals. It is possible to lose money by investing in the Portfolio.
