Short-Term Bond Fund | Short-Term Bond Fund

Short-Term Bond Fund

Investment Objective

The TDAM Short-Term Bond Fund (the “Fund”) seeks to provide a high level of income consistent with the preservation of capital and liquidity.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

Shareholder Transaction Fees (fees paid directly from your investment)

Shareholder Fees	Short-Term Bond Fund
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	none

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	Short-Term Bond Fund
Management Fees	0.25%
Distribution (12b-1) Fees	none
Other Expenses	0.31%
Total Annual Fund Operating Expenses	0.56%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then 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 Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
Short-Term Bond Fund	57	179	313	701

Portfolio Turnover

The Fund pays transaction costs, such as the payment of dealer spreads, 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 Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 176% of the average value of its portfolio.

Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in debt obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities, as well as investment-grade debt obligations (debt obligations rated in one of the four highest ratings categories by a nationally recognized statistical rating organization) of banks and corporations. An unrated debt obligation may be treated as investment-grade if warranted by the analysis of the Fund’s investment manager, TDAM USA Inc. (the “Investment Manager” or “TDAM”). In addition, under normal circumstances, the Investment Manager will maintain an average dollar-weighted maturity for the Fund of 3 years or less for securities which the Fund holds.

The Investment Manager will allocate the Fund’s assets across different market sectors (for example, corporate or government securities) and different maturities based on its view of the relative value of each sector or maturity.

In selecting investments for the Fund, the Investment Manager will analyze a security’s structural features and current price, trading opportunities and the credit quality of the issuer. The Fund may invest in mortgage-backed and asset-backed securities. The Fund may sell securities for a variety of reasons, such as to adjust the portfolio’s average maturity, duration, or credit quality or to shift assets into and out of higher yielding or lower yielding securities or different sectors.

In managing the Fund, the Investment Manager will use a proprietary investment philosophy, which places a strong emphasis on fundamental credit research. Pursuant to this philosophy, the Investment Manager will invest the assets of the Fund in securities that have a lower average credit quality than its benchmark index, the Merrill Lynch 1 – 3 Year Treasury Index, because such investments provide sufficient incremental income to justify their additional risk. Under normal circumstances, the Investment Manager will also seek to minimize deviations from the average duration of the Fund’s benchmark index, consistent with the belief that interest rate speculation is not appropriate for a long-term investment philosophy. In addition, the Investment Manager will seek to enhance returns by taking advantage of yield differentials among securities.

Principal Risks

If the Investment Manager’s strategies do not work as intended, the Fund may not achieve its investment objective.

Investment Risk — You could lose money on your investment in the Fund, or the Fund could underperform other investments.

Interest Rate Risk — Prices of fixed income securities generally increase when interest rates decline and decrease when interest rates rise. Interest rate risk is the risk that the Fund’s fixed-income securities will decline in value because of increases in market interest rates.

Credit Risk — Fixed income investments, such as bonds, involve credit risk. This is the risk that the issuer or credit enhancer will not make timely payments of principal and interest. The degree of credit risk depends on the issuer’s financial condition and on the terms of the debt instrument. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness also may affect the value of the Fund’s investment in that issuer.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Fund to reinvest its assets in lower yielding securities.

Mortgage-Backed Securities Risk — The value of the Fund’s mortgage-backed securities can fall if the owners of the underlying mortgages pay off their mortgages sooner than expected, which could happen when interest rates fall, or later than expected, which could happen when interest rates rise. If the underlying mortgages are paid off sooner than expected, the Fund may have to reinvest this money in mortgage-backed or other securities that have lower yields.

Asset-Backed Securities Risk — Payment of interest and repayment of principal may be impacted by the cash flows generated by the assets backing asset-backed securities. The value of the Fund’s asset-backed securities may also be affected by changes in interest rates, the availability of information concerning the interests in and structure of the pools of purchase contracts, financing leases or sales agreements that are represented by these securities, the creditworthiness of the servicing agent for the pool, the originator of the loans or receivables, or the entities that provide any supporting letters of credit, surety bonds, or other credit enhancements.

Banking Industry Risk — The Fund may invest a significant portion of its assets in obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Strategy [Heading]

rr_StrategyHeading

Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Institutional Money Market Fund is a money market fund. The Institutional Money Market Fund invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Institutional Money Market Fund’s investment manager, TDAM USA Inc. (the “Investment Manager” or “TDAM”), to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Institutional Money Market Fund invests in a broad spectrum of high quality U.S. dollar-denominated money market instruments. The Institutional Money Market Fund’s investments may include obligations issued by, or guaranteed by, U.S. or foreign governments, their agencies or instrumentalities, bank obligations, and corporate debt obligations of U.S. and foreign issuers, as well as repurchase agreements and other money market instruments. The Institutional Money Market Fund may also invest in short-term, high quality obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The municipal securities in which the Institutional Money Market Fund may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days. Although the income from many municipal securities is exempt from regular federal income tax, the Institutional Money Market Fund may invest in taxable municipal securities. The Institutional Money Market Fund does not anticipate that its investments in tax-exempt municipal securities will reach the level required by applicable law to permit it to make distributions to shareholders that are, in whole or in part, exempt from regular federal income tax. The Institutional Money Market Fund also invests in asset-backed securities and asset-backed commercial paper (collectively, “asset-backed securities”). Such securities directly or indirectly represent a participation interest in, or are secured by and are payable from, a stream of payments generated from particular assets, such as automobile and credit card receivables and home equity loans or other asset-backed securities collateralized by those assets.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Interest Rate Risk — The income from the Institutional Money Market Fund will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Institutional Money Market Fund to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

Asset-Backed Securities Risk — The value of asset-backed securities may be affected by the credit risk of the servicing agent for the pool, the originator of the loans or receivables, or the financial institution(s) providing the credit support. In addition to credit risk, asset-backed securities and other securities with early redemption features are subject to prepayment risk. During periods of declining interest rates, prepayment of loans underlying asset-backed securities can be expected to accelerate or an issuer may retire an outstanding bond early to reduce interest costs.

Banking Industry Risk — The Institutional Money Market Fund may invest a significant portion of its assets in obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional Money Market Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Institutional Money Market Fund. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Institutional Money Market Fund.

An investment in the Institutional Money Market Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Institutional Money Market Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Investment Strategies

The Institutional Municipal Fund is a money market fund. The Institutional Municipal Fund invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Institutional Municipal Fund invests primarily in a diversified portfolio of short-term, high quality, tax-exempt municipal obligations. The Institutional Municipal Fund normally invests at least 80% of its total assets in obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The income from these securities is exempt from regular federal income tax, but may be subject to the federal alternative minimum tax (“AMT”). The municipal securities in which the Institutional Municipal Fund may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Principal Risks

Interest Rate Risk — The income from the Institutional Municipal Fund will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Institutional Municipal Fund to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

Tax Risk — The Institutional Municipal Fund purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the investment manager nor the Institutional Municipal Fund guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to Institutional Municipal Fund shareholders could be recharacterized as taxable.

Banking Industry Risk — The Institutional Municipal Fund may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional Municipal Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Institutional Municipal Fund. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Institutional Municipal Fund.

An investment in the Institutional Municipal Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Institutional Municipal Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Performance

The following bar chart and table illustrate the risks of investing in the Institutional Class of the Institutional Municipal Fund. The bar chart shows changes in the Institutional Class’ performance from year to year. The returns for the Institutional Service Class of the Institutional Municipal Fund will vary from the returns of the Institutional Class as a result of differences in expenses applicable to each Class. The table shows average annual total returns of each Class of the Institutional Municipal Fund. Of course, past performance is not necessarily an indication of how the Institutional Municipal Fund will perform in the future.

Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in debt obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities, as well as investment-grade debt obligations (debt obligations rated in one of the four highest ratings categories by a nationally recognized statistical rating organization) of banks and corporations. An unrated debt obligation may be treated as investment-grade if warranted by the analysis of the Fund’s investment manager, TDAM USA Inc. (the “Investment Manager” or “TDAM”). In addition, under normal circumstances, the Investment Manager will maintain an average dollar-weighted maturity for the Fund of 3 years or less for securities which the Fund holds.

The Investment Manager will allocate the Fund’s assets across different market sectors (for example, corporate or government securities) and different maturities based on its view of the relative value of each sector or maturity.

In selecting investments for the Fund, the Investment Manager will analyze a security’s structural features and current price, trading opportunities and the credit quality of the issuer. The Fund may invest in mortgage-backed and asset-backed securities. The Fund may sell securities for a variety of reasons, such as to adjust the portfolio’s average maturity, duration, or credit quality or to shift assets into and out of higher yielding or lower yielding securities or different sectors.

In managing the Fund, the Investment Manager will use a proprietary investment philosophy, which places a strong emphasis on fundamental credit research. Pursuant to this philosophy, the Investment Manager will invest the assets of the Fund in securities that have a lower average credit quality than its benchmark index, the Merrill Lynch 1 – 3 Year Treasury Index, because such investments provide sufficient incremental income to justify their additional risk. Under normal circumstances, the Investment Manager will also seek to minimize deviations from the average duration of the Fund’s benchmark index, consistent with the belief that interest rate speculation is not appropriate for a long-term investment philosophy. In addition, the Investment Manager will seek to enhance returns by taking advantage of yield differentials among securities.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

If the Investment Manager’s strategies do not work as intended, the Fund may not achieve its investment objective.

Investment Risk — You could lose money on your investment in the Fund, or the Fund could underperform other investments.

Interest Rate Risk — Prices of fixed income securities generally increase when interest rates decline and decrease when interest rates rise. Interest rate risk is the risk that the Fund’s fixed-income securities will decline in value because of increases in market interest rates.

Credit Risk — Fixed income investments, such as bonds, involve credit risk. This is the risk that the issuer or credit enhancer will not make timely payments of principal and interest. The degree of credit risk depends on the issuer’s financial condition and on the terms of the debt instrument. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness also may affect the value of the Fund’s investment in that issuer.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Fund to reinvest its assets in lower yielding securities.

Mortgage-Backed Securities Risk — The value of the Fund’s mortgage-backed securities can fall if the owners of the underlying mortgages pay off their mortgages sooner than expected, which could happen when interest rates fall, or later than expected, which could happen when interest rates rise. If the underlying mortgages are paid off sooner than expected, the Fund may have to reinvest this money in mortgage-backed or other securities that have lower yields.

Asset-Backed Securities Risk — Payment of interest and repayment of principal may be impacted by the cash flows generated by the assets backing asset-backed securities. The value of the Fund’s asset-backed securities may also be affected by changes in interest rates, the availability of information concerning the interests in and structure of the pools of purchase contracts, financing leases or sales agreements that are represented by these securities, the creditworthiness of the servicing agent for the pool, the originator of the loans or receivables, or the entities that provide any supporting letters of credit, surety bonds, or other credit enhancements.

Banking Industry Risk — The Fund may invest a significant portion of its assets in obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Strategy [Heading]

rr_StrategyHeading

Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Municipal Portfolio is a money market fund. The Municipal Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Municipal Portfolio invests primarily in a diversified portfolio of short-term, high quality, tax-exempt municipal obligations. The Municipal Portfolio normally invests at least 80% of its total assets in obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The income from these securities is exempt from regular federal income tax, but may be subject to the federal alternative minimum tax (“AMT”). The municipal securities in which the Municipal Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Interest Rate Risk — The income from the Municipal Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Municipal Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

Tax Risk — The Municipal Portfolio purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the investment manager nor the Municipal Portfolio guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to Municipal Portfolio shareholders could be recharacterized as taxable.

Banking Industry Risk — The Municipal Portfolio may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Municipal Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Municipal Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Municipal Portfolio.

An investment in the Municipal Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Municipal Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

Investment Strategies

The Institutional U.S. Government Fund is a money market fund. The Institutional U.S. Government Fund invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Institutional U.S. Government Fund invests primarily in U.S. Treasury bills, notes, bonds and other obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities, and repurchase agreements backed by such obligations. The Institutional U.S. Government Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in government securities.

Principal Risks

Interest Rate Risk — The income from the Institutional U.S. Government Fund will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis. The Institutional U.S. Government Fund reduces credit risk by investing primarily in U.S. government and agency securities. However, not all of these securities in which the Institutional U.S. Government Fund may invest are backed by the full faith and credit of the U.S. government. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Institutional U.S. Government Fund to reinvest assets in lower yielding securities.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional U.S. Government Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Institutional U.S. Government Fund. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Institutional U.S. Government Fund.

An investment in the Institutional U.S. Government Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Institutional U.S. Government Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The New York Portfolio is a money market fund. The New York Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The New York Portfolio will normally invest at least 80% of its total assets in municipal securities, including those issued by the state of New York or the state’s political subdivisions, authorities or instrumentalities, or by corporations established for public purposes. These securities also may be issued by other qualified issuers, including the various territories and possessions of the United States, such as Puerto Rico. In the opinion of the issuer’s bond counsel, the income from these securities is exempt from the state of New York’s personal income tax and federal income tax. However, this income may be subject to the AMT. When suitable New York state tax-exempt securities are unavailable, the New York Portfolio may invest up to 20% of its assets in securities issued by other states and their political subdivisions whose income is exempt from federal income tax but is subject to state personal income tax. The municipal securities in which the New York Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Interest Rate Risk — The income from the New York Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the New York Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

New York Municipal Securities Risk — The yields of New York municipal securities depend on, among other things, conditions in the state’s municipal securities markets and debt securities markets generally, the size of a particular offering, the maturity of the obligation and the rating of the issue. Because the New York Portfolio will invest a large portion of its assets in New York municipal securities, it is more vulnerable to events adversely affecting the state of New York, including economic, political and regulatory occurrences or terrorism. New York’s economy, while diverse, has a relatively large share of the nation’s financial activities. As a result, the state’s economy is especially vulnerable to adverse events affecting the financial markets.

Non-Diversification Risk — The New York Portfolio’s “non-diversified” status allows it to invest more than 5% of its assets in a single issuer. As a result, the New York Portfolio is riskier than other types of money market funds that require greater diversification among issuers.

Tax Risk — The New York Portfolio purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the Investment Manager nor the New York Portfolio guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to New York Portfolio shareholders could be recharacterized as taxable.

Banking Industry Risk — The New York Portfolio may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the New York Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the New York Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the New York Portfolio.

An investment in the New York Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the New York Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Interest Rate Risk — The income from the U.S. Government Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis. The U.S. Government Portfolio reduces credit risk by investing primarily in U.S. government and agency securities. However, not all of these securities in which the U.S. Government Portfolio may invest are backed by the full faith and credit of the U.S. government. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the U.S. Government Portfolio to reinvest assets in lower yielding securities.

Investment Strategies

The Money Market Portfolio is a money market fund. The Money Market Portfolio invests in high quality money market securities that the Money Market Portfolio’s investment manager, TDAM USA Inc. (the “Investment Manager” or “TDAM”), believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Money Market Portfolio invests in a broad spectrum of high quality U.S. dollar-denominated money market instruments. The Money Market Portfolio’s investments may include obligations issued by, or guaranteed by, U.S. or foreign governments, their agencies or instrumentalities, bank obligations, and corporate debt obligations of U.S. and foreign issuers, as well as repurchase agreements and other money market instruments. The Money Market Portfolio may also invest in short-term, high quality obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The municipal securities in which the Money Market Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days. Although the income from many municipal securities is exempt from regular federal income tax, the Money Market Portfolio may invest in taxable municipal securities. The Money Market Portfolio does not anticipate that its investments in tax-exempt municipal securities will reach the level required by applicable law to permit it to make distributions to shareholders that are, in whole or in part, exempt from regular federal income tax. The Money Market Portfolio also invests in asset-backed securities and asset-backed commercial paper (collectively, “asset-backed securities”). Such securities directly or indirectly represent a participation interest in, or are secured by and are payable from, a stream of payments generated from particular assets, such as automobile and credit card receivables and home equity loans or other asset-backed securities collateralized by those assets. The credit quality of asset-backed securities purchased by the Money Market Portfolio is often improved in comparison to that of the underlying loans or receivables through credit enhancement and liquidity enhancement mechanisms. Forms of enhancement include letters of credit, surety bond guarantees, overcollateralization, excess spread protection, subordination of other classes of debt, early amortization and cash reserve accounts. Most programs utilize some or all of these forms of enhancement.

Principal Risks

Interest Rate Risk — The income from the Money Market Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Money Market Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

Asset-Backed Securities Risk — The value of asset-backed securities may be affected by the credit risk of the servicing agent for the pool, the originator of the loans or receivables, or the financial institution(s) providing the credit support. In addition to credit risk, asset-backed securities and other securities with early redemption features are subject to prepayment risk. During periods of declining interest rates, prepayment of loans underlying asset-backed securities can be expected to accelerate or an issuer may retire an outstanding bond early to reduce interest costs.

Banking Industry Risk — The Money Market Portfolio may invest a significant portion of its assets in obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Money Market Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Money Market Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Money Market Portfolio.

An investment in the Money Market Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Money Market Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

Investment Strategies

The U.S. Government Portfolio is a money market fund. The U.S. Government Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The U.S. Government Portfolio invests primarily in U.S. Treasury bills, notes, bonds and other obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities, and repurchase agreements backed by such obligations. The U.S. Government Portfolio normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in government securities.

Principal Risks

Interest Rate Risk — The income from the U.S. Government Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or at maturity in full on a timely basis. The U.S. Government Portfolio reduces credit risk by investing primarily in U.S. government and agency securities. However, not all of these securities in which the U.S. Government Portfolio may invest are backed by the full faith and credit of the U.S. government. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the U.S. Government Portfolio to reinvest assets in lower yielding securities.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the U.S. Government Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the U.S. Government Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the U.S. Government Portfolio.

An investment in the U.S. Government Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the U.S. Government Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

The Money Market Portfolio is a money market fund. The Money Market Portfolio invests in high quality money market securities that the Money Market Portfolio’s investment manager, TDAM USA Inc. (the “Investment Manager” or “TDAM”), believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Money Market Portfolio invests in a broad spectrum of high quality U.S. dollar-denominated money market instruments. The Money Market Portfolio’s investments may include obligations issued by, or guaranteed by, U.S. or foreign governments, their agencies or instrumentalities, bank obligations, and corporate debt obligations of U.S. and foreign issuers, as well as repurchase agreements and other money market instruments. The Money Market Portfolio may also invest in short-term, high quality obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The municipal securities in which the Money Market Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days. Although the income from many municipal securities is exempt from regular federal income tax, the Money Market Portfolio may invest in taxable municipal securities. The Money Market Portfolio does not anticipate that its investments in tax-exempt municipal securities will reach the level required by applicable law to permit it to make distributions to shareholders that are, in whole or in part, exempt from regular federal income tax. The Money Market Portfolio also invests in asset-backed securities and asset-backed commercial paper (collectively, “asset-backed securities”). Such securities directly or indirectly represent a participation interest in, or are secured by and are payable from, a stream of payments generated from particular assets, such as automobile and credit card receivables and home equity loans or other asset-backed securities collateralized by those assets. The credit quality of asset-backed securities purchased by the Money Market Portfolio is often improved in comparison to that of the underlying loans or receivables through credit enhancement and liquidity enhancement mechanisms. Forms of enhancement include letters of credit, surety bond guarantees, overcollateralization, excess spread protection, subordination of other classes of debt, early amortization and cash reserve accounts. Most programs utilize some or all of these forms of enhancement.

Principal Risks

Risk Narrative [Text Block]

Interest Rate Risk — The income from the Money Market Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Money Market Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

Asset-Backed Securities Risk — The value of asset-backed securities may be affected by the credit risk of the servicing agent for the pool, the originator of the loans or receivables, or the financial institution(s) providing the credit support. In addition to credit risk, asset-backed securities and other securities with early redemption features are subject to prepayment risk. During periods of declining interest rates, prepayment of loans underlying asset-backed securities can be expected to accelerate or an issuer may retire an outstanding bond early to reduce interest costs.

Banking Industry Risk — The Money Market Portfolio may invest a significant portion of its assets in obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Money Market Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Money Market Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Money Market Portfolio.

An investment in the Money Market Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

The California Portfolio is a money market fund. The California Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The California Portfolio will normally invest at least 80% of its total assets in municipal securities, including those issued by the state of California or the state’s political subdivisions, authorities or instrumentalities, or by corporations established for public purposes. These securities also may be issued by other qualified issuers, including the various territories and possessions of the United States, such as Puerto Rico. In the opinion of the issuer’s bond counsel, the income from these securities is exempt from the state of California’s personal income tax and federal income tax. However, this income may be subject to the AMT. When suitable California state tax-exempt securities are unavailable, the California Portfolio may invest up to 20% of its assets in securities issued by other states and their political subdivisions whose income is exempt from federal income tax but is subject to state personal income tax. The municipal securities in which the California Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Interest Rate Risk — The income from the California Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the California Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

California Municipal Securities Risk — The yields of California municipal securities depend on, among other things, conditions in the state’s municipal securities markets and debt securities markets generally, the size of a particular offering, the maturity of the obligation and the rating of the issue. Because the California Portfolio will invest a large portion of its assets in California municipal securities, it is more vulnerable to events adversely affecting the state of California, including economic, political and regulatory occurrences or terrorism. While California’s economy is relatively diverse and thereby less vulnerable to events affecting a particular industry, it continues to be affected by serious fiscal conditions and voter-passed initiatives limit the State’s ability to raise revenues, particularly with respect to real property taxes. California’s economy may also be affected by natural disasters, such as earthquakes or fires.

Non-Diversification Risk — The California Portfolio’s “non-diversified” status allows it to invest more than 5% of its assets in a single issuer. As a result, the California Portfolio is riskier than other types of money market funds that require greater diversification among issuers.

Tax Risk — The California Portfolio purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the Investment Manager nor the California Portfolio guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to California Portfolio shareholders could be recharacterized as taxable.

Banking Industry Risk — The California Portfolio may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the California Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the California Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the California Portfolio.

An investment in the California Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the California Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

Investment Strategies

The Institutional Money Market Fund is a money market fund. The Institutional Money Market Fund invests in high quality money market securities that the Institutional Money Market Fund’s investment manager, TDAM USA Inc. (the “Investment Manager” or “TDAM”), believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Institutional Money Market Fund invests in a broad spectrum of high quality U.S. dollar-denominated money market instruments. The Institutional Money Market Fund’s investments may include obligations issued by, or guaranteed by, U.S. or foreign governments, their agencies or instrumentalities, bank obligations, and corporate debt obligations of U.S. and foreign issuers, as well as repurchase agreements and other money market instruments. The Institutional Money Market Fund may also invest in short-term, high quality obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The municipal securities in which the Institutional Money Market Fund may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days. Although the income from many municipal securities is exempt from regular federal income tax, the Institutional Money Market Fund may invest in taxable municipal securities. The Institutional Money Market Fund does not anticipate that its investments in tax-exempt municipal securities will reach the level required by applicable law to permit it to make distributions to shareholders that are, in whole or in part, exempt from regular federal income tax. The Institutional Money Market Fund also invests in asset-backed securities and asset-backed commercial paper (collectively, “asset-backed securities”). Such securities directly or indirectly represent a participation interest in, or are secured by and are payable from, a stream of payments generated from particular assets, such as automobile and credit card receivables and home equity loans or other asset-backed securities collateralized by those assets.

Principal Risks

Interest Rate Risk — The income from the Institutional Money Market Fund will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Institutional Money Market Fund to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

Asset-Backed Securities Risk — The value of asset-backed securities may be affected by the credit risk of the servicing agent for the pool, the originator of the loans or receivables, or the financial institution(s) providing the credit support. In addition to credit risk, asset-backed securities and other securities with early redemption features are subject to prepayment risk. During periods of declining interest rates, prepayment of loans underlying asset-backed securities can be expected to accelerate or an issuer may retire an outstanding bond early to reduce interest costs.

Banking Industry Risk — The Institutional Money Market Fund may invest a significant portion of its assets in obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional Money Market Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Institutional Money Market Fund. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Institutional Money Market Fund.

An investment in the Institutional Money Market Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Institutional Money Market Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Investment Strategies

The U.S. Government Portfolio is a money market fund. The U.S. Government Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The U.S. Government Portfolio invests primarily in U.S. Treasury bills, notes, bonds and other obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities, and repurchase agreements backed by such obligations. The U.S. Government Portfolio normally invests at least 80% of its net assets (plus borrowings for investment purposes) in government securities.

Principal Risks

Interest Rate Risk — The income from the U.S. Government Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis. The U.S. Government Portfolio reduces credit risk by investing primarily in U.S. government and agency securities. However, not all of these securities in which the U.S. Government Portfolio may invest are backed by the full faith and credit of the U.S. government. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the U.S. Government Portfolio to reinvest assets in lower yielding securities.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the U.S. Government Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the U.S. Government Portfolio.

Investment Strategies

The New York Portfolio is a money market fund. The New York Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The New York Portfolio will normally invest at least 80% of its total assets in municipal securities, including those issued by the state of New York or the state’s political subdivisions, authorities or instrumentalities, or by corporations established for public purposes. These securities also may be issued by other qualified issuers, including the various territories and possessions of the United States, such as Puerto Rico. In the opinion of the issuer’s bond counsel, the income from these securities is exempt from the state of New York’s personal income tax and federal income tax. However, this income may be subject to the AMT. When suitable New York state tax-exempt securities are unavailable, the New York Portfolio may invest up to 20% of its assets in securities issued by other states and their political subdivisions whose income is exempt from federal income tax but is subject to state personal income tax. The municipal securities in which the New York Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Principal Risks

Interest Rate Risk — The income from the New York Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the New York Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

New York Municipal Securities Risk — The yields of New York municipal securities depend on, among other things, conditions in the state’s municipal securities markets and debt securities markets generally, the size of a particular offering, the maturity of the obligation and the rating of the issue. Because the New York Portfolio will invest a large portion of its assets in New York municipal securities, it is more vulnerable to events adversely affecting the state of New York, including economic, political and regulatory occurrences or terrorism. New York’s economy, while diverse, has a relatively large share of the nation’s financial activities. As a result, the state’s economy is especially vulnerable to adverse events affecting the financial markets.

Non-Diversification Risk — The New York Portfolio’s “non-diversified” status allows it to invest more than 5% of its assets in a single issuer. As a result, the New York Portfolio is riskier than other types of money market funds that require greater diversification among issuers.

Tax Risk — The New York Portfolio purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the Investment Manager nor the New York Portfolio guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to New York Portfolio shareholders could be recharacterized as taxable.

Banking Industry Risk — The New York Portfolio may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the New York Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the New York Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the New York Portfolio.

An investment in the New York Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the New York Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

Forms of enhancement include letters of credit, surety bond guarantees, overcollateralization, excess spread protection, subordination of other classes of debt, early amortization and cash reserve accounts. Most programs utilize some or all of these forms of enhancement.

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
TDAM Institutional Treasury Obligations Money Market Fund Commercial Class	97	303	525	1,166

Investment Strategies

The Institutional Treasury Fund is a money market fund. The Institutional Treasury Fund invests 100% of its net assets (plus any borrowings for investment purposes) in U.S. Treasury obligations, repurchase agreements backed by such obligations and cash. This investment policy can be changed by the Institutional Treasury Fund upon 60 days’ notice to shareholders. In selecting investments for the Institutional Treasury Fund, the Investment Manager tries to increase income, without adding undue risk, by analyzing yields. The Investment Manager manages the maturity of the Institutional Treasury Fund and its portfolio to maximize the Institutional Treasury Fund’s yield based on current market interest rates and the Investment Manager’s outlook on the market, subject to the legal requirements applicable to money market funds. The Institutional Treasury Fund’s Statement of Additional Information (“SAI”) contains more information about the investments and strategies described in this Prospectus.

Principal Risks

Income/Interest Rate Risk — The income from the Institutional Treasury Fund will vary with changes in prevailing interest rates. The market value of fixed income investments changes in response to interest rate changes and other factors. During periods of rising interest rates, the values of outstanding fixed income securities generally fall. Moreover, while securities with longer maturities tend to produce higher yields, the prices of longer maturity securities

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional Treasury Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Institutional Treasury Fund. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Institutional Treasury Fund.

An investment in the Institutional Treasury Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Institutional Treasury Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Performance

The bar chart shows changes in the Commercial Class’ performance from year to year. The table shows average annual total returns of the Institutional Treasury Fund. Of course, past performance is not necessarily an indication of how the Institutional Treasury Fund will perform in the future.

Investment Strategies

The Institutional Money Market Fund is a money market fund. The Institutional Money Market Fund invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Institutional Money Market Fund’s investment manager, TDAM USA Inc. (the “Investment Manager” or “TDAM”), to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Institutional Money Market Fund invests in a broad spectrum of high quality U.S. dollar-denominated money market instruments. The Institutional Money Market Fund’s investments may include obligations issued by, or guaranteed by, U.S. or foreign governments, their agencies or instrumentalities, bank obligations, and corporate debt obligations of U.S. and foreign issuers, as well as repurchase agreements and other money market instruments. The Institutional Money Market Fund may also invest in short-term, high quality obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The municipal securities in which the Institutional Money Market Fund may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days. Although the income from many municipal securities is exempt from regular federal income tax, the Institutional Money Market Fund may invest in taxable municipal securities. The Institutional Money Market Fund does not anticipate that its investments in tax-exempt municipal securities will reach the level required by applicable law to permit it to make distributions to shareholders that are, in whole or in part, exempt from regular federal income tax. The Institutional Money Market Fund also invests in asset-backed securities and asset-backed commercial paper (collectively, “asset-backed securities”). Such securities directly or indirectly represent a participation interest in, or are secured by and are payable from, a stream of payments generated from particular assets, such as automobile and credit card receivables and home equity loans or other asset-backed securities collateralized by those assets.

Principal Risks

Interest Rate Risk — The income from the Institutional Money Market Fund will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Institutional Money Market Fund to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

Asset-Backed Securities Risk — The value of asset-backed securities may be affected by the credit risk of the servicing agent for the pool, the originator of the loans or receivables, or the financial institution(s) providing the credit support. In addition to credit risk, asset-backed securities and other securities with early redemption features are subject to prepayment risk. During periods of declining interest rates, prepayment of loans underlying asset-backed securities can be expected to accelerate or an issuer may retire an outstanding bond early to reduce interest costs.

Banking Industry Risk — The Institutional Money Market Fund may invest a significant portion of its assets in obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional Money Market Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Institutional Money Market Fund. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Institutional Money Market Fund.

An investment in the Institutional Money Market Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Institutional Money Market Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

The credit quality of asset-backed securities purchased by the Money Market Portfolio is often improved in comparison to that of the underlying loans or receivables through credit enhancement and liquidity enhancement mechanisms. Forms of enhancement include letters of credit, surety bond guarantees, overcollateralization, excess spread protection, subordination of other classes of debt, early amortization and cash reserve accounts. Most programs utilize some or all of these forms of enhancement.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis. The Institutional U.S. Government Fund reduces credit risk by investing primarily in U.S. government and agency securities. However, not all of these securities in which the Institutional U.S. Government Fund may invest are backed by the full faith and credit of the U.S. government. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Institutional U.S. Government Fund to reinvest assets in lower yielding securities.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional U.S. Government Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Income/Interest Rate Risk — The income from the Institutional Treasury Fund will vary with changes in prevailing interest rates. The market value of fixed income investments changes in response to interest rate changes and other factors. During periods of rising interest rates, the values of outstanding fixed income securities generally fall. Moreover, while securities with longer maturities tend to produce higher yields, the prices of longer maturity securities are also subject to greater market fluctuation as a result of changes in interest rates. Although the Institutional Treasury Fund’s U.S. Treasury securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional Treasury Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Institutional Treasury Fund. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Institutional Treasury Fund.

An investment in the Institutional Treasury Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Institutional Treasury Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
TDAM New York Municipal Money Market Portfolio Class A	112	350	606	1,340

Investment Strategies

The New York Portfolio is a money market fund. The New York Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The New York Portfolio will normally invest at least 80% of its total assets in municipal securities, including those issued by the state of New York or the state’s political subdivisions, authorities or instrumentalities, or by corporations established for public purposes. These securities also may be issued by other qualified issuers, including the various territories and possessions of the United States, such as Puerto Rico. In the opinion of the issuer’s bond counsel, the income from these securities is exempt from the state of New York’s personal income tax and federal income tax. However, this income may be subject to the AMT. When suitable New York state tax-exempt securities are unavailable, the New York Portfolio may invest up to 20% of its assets in securities issued by other states and their political subdivisions whose income is exempt from federal income tax but is subject to state personal income tax. The municipal securities in which the New York Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Principal Risks

Interest Rate Risk — The income from the New York Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the New York Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

New York Municipal Securities Risk — The yields of New York municipal securities depend on, among other things, conditions in the state’s municipal securities markets and debt securities markets generally, the size of a particular offering, the maturity of the obligation and the rating of the issue. Because the New York Portfolio will invest a large portion of its assets in New York municipal securities, it is more vulnerable to events adversely affecting the state of New York, including economic, political and regulatory occurrences or terrorism. New York’s economy, while diverse, has a relatively large share of the nation’s financial activities. As a result, the state’s economy is especially vulnerable to adverse events affecting the financial markets.

Non-Diversification Risk — The New York Portfolio’s “non-diversified” status allows it to invest more than 5% of its assets in a single issuer. As a result, the New York Portfolio is riskier than other types of money market funds that require greater diversification among issuers.

Tax Risk — The New York Portfolio purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the Investment Manager nor the New York Portfolio guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to New York Portfolio shareholders could be recharacterized as taxable.

Banking Industry Risk — The New York Portfolio may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the New York Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the New York Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the New York Portfolio.

An investment in the New York Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the New York Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The New York Portfolio will normally invest at least 80% of its total assets in municipal securities, including those issued by the state of New York or the state’s political subdivisions, authorities or instrumentalities, or by corporations established for public purposes. These securities also may be issued by other qualified issuers, including the various territories and possessions of the United States, such as Puerto Rico. In the opinion of the issuer’s bond counsel, the income from these securities is exempt from the state of New York’s personal income tax and federal income tax. However, this income may be subject to the AMT. When suitable New York state tax-exempt securities are unavailable, the New York Portfolio may invest up to 20% of its assets in securities issued by other states and their political subdivisions whose income is exempt from federal income tax but is subject to state personal income tax. The municipal securities in which the New York Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Interest Rate Risk — The income from the New York Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the New York Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

New York Municipal Securities Risk — The yields of New York municipal securities depend on, among other things, conditions in the state’s municipal securities markets and debt securities markets generally, the size of a particular offering, the maturity of the obligation and the rating of the issue. Because the New York Portfolio will invest a large portion of its assets in New York municipal securities, it is more vulnerable to events adversely affecting the state of New York, including economic, political and regulatory occurrences or terrorism. New York’s economy, while diverse, has a relatively large share of the nation’s financial activities. As a result, the state’s economy is especially vulnerable to adverse events affecting the financial markets.

Non-Diversification Risk — The New York Portfolio’s “non-diversified” status allows it to invest more than 5% of its assets in a single issuer. As a result, the New York Portfolio is riskier than other types of money market funds that require greater diversification among issuers.

Tax Risk — The New York Portfolio purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the Investment Manager nor the New York Portfolio guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to New York Portfolio shareholders could be recharacterized as taxable.

Banking Industry Risk — The New York Portfolio may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the New York Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the New York Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the New York Portfolio.

An investment in the New York Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the New York Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

TDAM Institutional Treasury Obligations Money Market Fund Institutional Service Class	45	141	246	555

Investment Strategies

The Institutional Treasury Fund is a money market fund. The Institutional Treasury Fund invests 100% of its net assets (plus any borrowings for investment purposes) in U.S. Treasury obligations, repurchase agreements backed by such obligations and cash. This investment policy can be changed by the Institutional Treasury Fund upon 60 days’ notice to shareholders. In selecting investments for the Institutional Treasury Fund, the Investment Manager tries to increase income, without adding undue risk, by analyzing yields. The Investment Manager manages the maturity of the Institutional Treasury Fund and its portfolio to maximize the Institutional Treasury Fund’s yield based on current market interest rates and the Investment Manager’s outlook on the market, subject to the legal requirements applicable to money market funds. The Institutional Treasury Fund’s Statement of Additional Information (“SAI”) contains more information about the investments and strategies described in this Prospectus.

Principal Risks

Income/Interest Rate Risk — The income from the Institutional Treasury Fund will vary with changes in prevailing interest rates. The market value of fixed income investments changes in response to interest rate changes and other factors. During periods of rising interest rates, the values of outstanding fixed income securities generally fall. Moreover, while securities with longer maturities tend to produce higher yields, the prices of longer maturity securities are also subject to greater market fluctuation as a result of changes in interest rates. Although the Institutional Treasury Fund’s U.S. Treasury securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional Treasury Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Institutional Treasury Fund. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Institutional Treasury Fund.

An investment in the Institutional Treasury Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Institutional Treasury Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Investment Strategies

The California Portfolio is a money market fund. The California Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The California Portfolio will normally invest at least 80% of its total assets in municipal securities, including those issued by the state of California or the state’s political subdivisions, authorities or instrumentalities, or by corporations established for public purposes. These securities also may be issued by other qualified issuers, including the various territories and possessions of the United States, such as Puerto Rico. In the opinion of the issuer’s bond counsel, the income from these securities is exempt from the state of California’s personal income tax and federal income tax. However, this income may be subject to the AMT. When suitable California state tax-exempt securities are unavailable, the California Portfolio may invest up to 20% of its assets in securities issued by other states and their political subdivisions whose income is exempt from federal income tax but is subject to state personal income tax. The municipal securities in which the California Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

California Municipal Securities Risk — The yields of California municipal securities depend on, among other things, conditions in the state’s municipal securities markets and debt securities markets generally, the size of a particular offering, the maturity of the obligation and the rating of the issue. Because the California Portfolio will invest a large portion of its assets in California municipal securities, it is more vulnerable to events adversely affecting the state of California, including economic, political and regulatory occurrences or terrorism. While California’s economy is relatively diverse and thereby less vulnerable to events affecting a particular industry, it continues to be affected by serious fiscal conditions and voter-passed initiatives limit the State’s ability to raise revenues, particularly with respect to real property taxes. California’s economy may also be affected by natural disasters, such as earthquakes or fires.

Non-Diversification Risk — The California Portfolio’s “non-diversified” status allows it to invest more than 5% of its assets in a single issuer. As a result, the California Portfolio is riskier than other types of money market funds that require greater diversification among issuers.

Tax Risk — The California Portfolio purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Interest Rate Risk — The income from the U.S. Government Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or at maturity in full on a timely basis. The U.S. Government Portfolio reduces credit risk by investing primarily in U.S. government and agency securities. However, not all of these securities in which the U.S. Government Portfolio may invest are backed by the full faith and credit of the U.S. government. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the U.S. Government Portfolio to reinvest assets in lower yielding securities.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the U.S. Government Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the U.S. Government Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the U.S. Government Portfolio.

An investment in the U.S. Government Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the U.S. Government Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

TDAM Municipal Portfolio

Investment Objective

The TDAM Municipal Portfolio (the “Municipal Portfolio”) seeks maximum current income to the extent consistent with liquidity and preservation of capital and a stable price of $1.00 per share.

Fees and Expenses of the Portfolio

This table describes the fees and expenses that you may pay if you buy and hold shares of the Municipal Portfolio.

Shareholder Fees (fees paid directly from your investment)

Shareholder Fees	TDAM Municipal Portfolio Investor Class
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	none

Annual Portfolio Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Distribution (12b-1) Fees	0.45%
Shareholder Servicing Fees	0.25%
All Other Expenses	0.15%
Total Other Expenses	0.40%
Total Annual Portfolio Operating Expenses	0.95%

Example

This Example is intended to help you compare the cost of investing in the Municipal Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Municipal 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 Municipal Portfolio’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
TDAM Municipal Portfolio Investor Class	97	303	525	1,166

Investment Strategies

The Municipal Portfolio is a money market fund. The Municipal Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Municipal Portfolio invests primarily in a diversified portfolio of short-term, high quality, tax-exempt municipal obligations. The Municipal Portfolio normally invests at least 80% of its total assets in obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The income from these securities is exempt from regular federal income tax, but may be subject to the federal alternative minimum tax (“AMT”). The municipal securities in which the Municipal Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Principal Risks

Interest Rate Risk — The income from the Municipal Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Municipal Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

Tax Risk — The Municipal Portfolio purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the investment manager nor the Municipal Portfolio guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to Municipal Portfolio shareholders could be recharacterized as taxable.

Banking Industry Risk — The Municipal Portfolio may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Municipal Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Municipal Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Municipal Portfolio.

An investment in the Municipal Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Municipal Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

The California Portfolio is a money market fund. The California Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The California Portfolio will normally invest at least 80% of its total assets in municipal securities, including those issued by the state of California or the state’s political subdivisions, authorities or instrumentalities, or by corporations established for public purposes. These securities also may be issued by other qualified issuers, including the various territories and possessions of the United States, such as Puerto Rico. In the opinion of the issuer’s bond counsel, the income from these securities is exempt from the state of California’s personal income tax and federal income tax. However, this income may be subject to the AMT. When suitable California state tax-exempt securities are unavailable, the California Portfolio may invest up to 20% of its assets in securities issued by other states and their political subdivisions whose income is exempt from federal income tax but is subject to state personal income tax. The municipal securities in which the California Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Such prepayments often occur during periods of declining interest rates, and may cause the California Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

California Municipal Securities Risk — The yields of California municipal securities depend on, among other things, conditions in the state’s municipal securities markets and debt securities markets generally, the size of a particular offering, the maturity of the obligation and the rating of the issue. Because the California Portfolio will invest a large portion of its assets in California municipal securities, it is more vulnerable to events adversely affecting the state of California, including economic, political and regulatory occurrences or terrorism. While California’s economy is relatively diverse and thereby less vulnerable to events affecting a particular industry, it continues to be affected by serious fiscal conditions and voter-passed initiatives that limit the State’s ability to raise revenues, particularly with respect to real property taxes. California’s economy may also be affected by natural disasters, such as earthquakes or fires.

Non-Diversification Risk — The California Portfolio’s “non-diversified” status allows it to invest more than 5% of its assets in a single issuer. As a result, the California Portfolio is riskier than other types of money market funds that require greater diversification among issuers.

Tax Risk — The California Portfolio purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the Investment Manager nor the California Portfolio guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to California Portfolio shareholders could be recharacterized as taxable.

Banking Industry Risk — The California Portfolio may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the California Portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Institutional Municipal Fund is a money market fund. The Institutional Municipal Fund invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Institutional Municipal Fund invests primarily in a diversified portfolio of short-term, high quality, tax-exempt municipal obligations. The Institutional Municipal Fund normally invests at least 80% of its total assets in obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The income from these securities is exempt from regular federal income tax, but may be subject to the federal alternative minimum tax (“AMT”). The municipal securities in which the Institutional Municipal Fund may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Interest Rate Risk — The income from the Institutional Municipal Fund will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Institutional Municipal Fund to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

Tax Risk — The Institutional Municipal Fund purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the investment manager nor the Institutional Municipal Fund guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to Institutional Municipal Fund shareholders could be recharacterized as taxable.

Banking Industry Risk — The Institutional Municipal Fund may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional Municipal Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Institutional Municipal Fund. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Institutional Municipal Fund.

An investment in the Institutional Municipal Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Institutional Municipal Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Interest Rate Risk — The income from the Institutional U.S. Government Fund will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis. The Institutional U.S. Government Fund reduces credit risk by investing primarily in U.S. government and agency securities. However, not all of these securities in which the Institutional U.S. Government Fund may invest are backed by the full faith and credit of the U.S. government. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Institutional U.S. Government Fund to reinvest assets in lower yielding securities.

Investment Strategies

The Municipal Portfolio is a money market fund. The Municipal Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Municipal Portfolio normally invests at least 80% of its total assets in obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The income from these securities is exempt from regular federal income tax, but may be subject to the federal alternative minimum tax (“AMT”). The municipal securities in which the Municipal Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Principal Risks

Interest Rate Risk — The income from the Municipal Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Municipal Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers.

If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to Municipal Portfolio shareholders could be recharacterized as taxable.

Banking Industry Risk — The Municipal Portfolio may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Municipal Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Municipal Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Municipal Portfolio.

Example

This Example is intended to help you compare the cost of investing in the Institutional U.S. Government Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Institutional U.S. Government Fund 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 Institutional U.S. Government Fund’s operating expenses remain the same.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Investment Strategies

The Institutional U.S. Government Fund is a money market fund. The Institutional U.S. Government Fund invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Institutional U.S. Government Fund invests primarily in U.S. Treasury bills, notes, bonds and other obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities, and repurchase agreements backed by such obligations. The Institutional U.S. Government Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in government securities.

Principal Risks

Interest Rate Risk — The income from the Institutional U.S. Government Fund will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis. The Institutional U.S. Government Fund reduces credit risk by investing primarily in U.S. government and agency securities. However, not all of these securities in which the Institutional U.S. Government Fund may invest are backed by the full faith and credit of the U.S. government. There is no guarantee that the U.S. government will support securities not backed by its full faith and credit.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the Institutional U.S. Government Fund to reinvest assets in lower yielding securities.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional U.S. Government Fund. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the Institutional U.S. Government Fund. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the Institutional U.S. Government Fund.

An investment in the Institutional U.S. Government Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Institutional U.S. Government Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Investment Strategies

The California Portfolio is a money market fund. The California Portfolio invests in high quality money market securities that the Investment Manager believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The California Portfolio will normally invest at least 80% of its total assets in municipal securities, including those issued by the state of California or the state’s political subdivisions, authorities or instrumentalities, or by corporations established for public purposes. These securities also may be issued by other qualified issuers, including the various territories and possessions of the United States, such as Puerto Rico. In the opinion of the issuer’s bond counsel, the income from these securities is exempt from the state of California’s personal income tax and federal income tax. However, this income may be subject to the AMT. When suitable California state tax-exempt securities are unavailable, the California Portfolio may invest up to 20% of its assets in securities issued by other states and their political subdivisions whose income is exempt from federal income tax but is subject to state personal income tax. The municipal securities in which the California Portfolio may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days.

Principal Risks

Interest Rate Risk — The income from the California Portfolio will vary with changes in prevailing interest rates.

Credit Risk — Fixed income investments involve credit risk. This is the risk that the issuer or credit enhancer will be unable, or will be perceived to be unable, to repay its coupon or maturity in full on a timely basis.

Prepayment Risk — Prepayment risk is the risk that the ability of an issuer of a debt security to repay principal prior to a security’s maturity can cause greater price volatility if interest rates change. Such prepayments often occur during periods of declining interest rates, and may cause the California Portfolio to reinvest assets in lower yielding securities.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

California Municipal Securities Risk — The yields of California municipal securities depend on, among other things, conditions in the state’s municipal securities markets and debt securities markets generally, the size of a particular offering, the maturity of the obligation and the rating of the issue. Because the California Portfolio will invest a large portion of its assets in California municipal securities, it is more vulnerable to events adversely affecting the state of California, including economic, political and regulatory occurrences or terrorism. While California’s economy is relatively diverse and thereby less vulnerable to events affecting a particular industry, it continues to be affected by serious fiscal conditions and voter-passed initiatives that limit the State’s ability to raise revenues, particularly with respect to real property taxes. California’s economy may also be affected by natural disasters, such as earthquakes or fires.

Non-Diversification Risk — The California Portfolio’s “non-diversified” status allows it to invest more than 5% of its assets in a single issuer. As a result, the California Portfolio is riskier than other types of money market funds that require greater diversification among issuers.

Tax Risk — The California Portfolio purchases municipal securities, the interest on which, in the opinion of bond counsel, is exempt from federal income tax. Neither the Investment Manager nor the California Portfolio guarantees that this opinion is correct and there is no assurance that the Internal Revenue Service (the “IRS”) will agree with bond counsel’s opinion. If the IRS determines that an issuer of a municipal security has not complied with applicable tax requirements, then interest from the security could become subject to federal income tax, possibly retroactively to the date the security was issued, the value of the security could decline significantly and a portion of the distributions to California Portfolio shareholders could be recharacterized as taxable.

Banking Industry Risk — The California Portfolio may invest a significant portion of its assets in obligations that are backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the California Portfolio. In addition, the SEC has adopted amendments to money market regulation, imposing new liquidity, credit quality, and maturity requirements on all money market funds. These changes may result in reduced yields for money market funds, including the California Portfolio. The SEC or Congress may adopt additional reforms to money market regulation, which may impact the operation or performance of the California Portfolio.

An investment in the California Portfolio is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the California Portfolio seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Portfolio.

The Institutional Money Market Fund is a money market fund. The Institutional Money Market Fund invests in high quality money market securities that the Institutional Money Market Fund’s investment manager, TDAM USA Inc. (the “Investment Manager” or “TDAM”), believes present minimal credit risk. To be considered high-quality, a security generally must be rated in one of the two highest credit-quality categories for short-term securities by at least two nationally recognized rating services (or by one, if only one rating service has rated the security). If unrated, the security must be determined by the Investment Manager to be of quality equivalent to securities in the two highest credit-quality categories.

Generally, money market securities are short-term debt obligations issued by banks, corporations or governments. Money market securities may be backed by loans, receivables or other assets or may be unsecured, and may include repurchase agreements.

The Institutional Money Market Fund invests in a broad spectrum of high quality U.S. dollar-denominated money market instruments. The Institutional Money Market Fund’s investments may include obligations issued by, or guaranteed by, U.S. or foreign governments, their agencies or instrumentalities, bank obligations, and corporate debt obligations of U.S. and foreign issuers, as well as repurchase agreements and other money market instruments. The Institutional Money Market Fund may also invest in short-term, high quality obligations issued or guaranteed by states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities (“municipal securities”). The municipal securities in which the Institutional Money Market Fund may invest include variable rate demand notes (VRDNs), which are obligations that contain a floating or variable interest rate adjustment formula and an unconditional right of demand to receive payment of the unpaid principal balance plus accrued interest upon a short notice period, generally not to exceed seven days. Although the income from many municipal securities is exempt from regular federal income tax, the Institutional Money Market Fund may invest in taxable municipal securities. The Institutional Money Market Fund does not anticipate that its investments in tax-exempt municipal securities will reach the level required by applicable law to permit it to make distributions to shareholders that are, in whole or in part, exempt from regular federal income tax. The Institutional Money Market Fund also invests in asset-backed securities and asset-backed commercial paper (collectively, “asset-backed securities”). Such securities directly or indirectly represent a participation interest in, or are secured by and are payable from, a stream of payments generated from particular assets, such as automobile and credit card receivables and home equity loans or other asset-backed securities collateralized by those assets.

Municipal Securities Risk — Municipal securities can be significantly affected by unfavorable economic, legislative or political developments and adverse changes in the financial conditions of issuers. Liquidity in the municipal securities market can be reduced unpredictably in response to overall economic conditions or credit tightening.

Asset-Backed Securities Risk — The value of asset-backed securities may be affected by the credit risk of the servicing agent for the pool, the originator of the loans or receivables, or the financial institution(s) providing the credit support. In addition to credit risk, asset-backed securities and other securities with early redemption features are subject to prepayment risk. During periods of declining interest rates, prepayment of loans underlying asset-backed securities can be expected to accelerate or an issuer may retire an outstanding bond early to reduce interest costs.

Banking Industry Risk — The Institutional Money Market Fund may invest a significant portion of its assets in obligations that are issued or backed by U.S. and non-U.S. banks, and thus will be more susceptible to negative events affecting the worldwide banking industry.

Regulatory Risk — Changes in government regulations may adversely affect the value of a security held by the Institutional Money Market Fund.
