Risk [Text Block]

All investments carry some degree of risk that will affect the value of the Fund, its investment performance, and the price of its shares. As a result, you may lose money if you invest in the Fund.

 

The shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other government agency.

 

The Fund is subject to the following principal investment risks:

 

Grandeur Peak Emerging Markets Opportunities Fund | Market And Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, tariffs and trade wars, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.

 

Grandeur Peak Emerging Markets Opportunities Fund | Stock Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Stock Market Risk. The Fund’s investments may decline due to movements in the overall stock market. Factors such as domestic and foreign economic growth and market conditions, interest rate levels, political events, natural disasters and the spread of infectious illness or other public health issues affect the securities and derivatives markets. Particularly during periods of declining or illiquid markets, the Fund may experience periods of heavy redemptions that could cause the Fund to liquidate its assets at inopportune times or at a loss or depressed value and could cause the remaining shareholders in the Fund to lose money.

 

Grandeur Peak Emerging Markets Opportunities Fund | Stock Selection Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Stock Selection Risk. The Fund’s investments may decline in value even when the overall stock market is not in a general decline.

 

Grandeur Peak Emerging Markets Opportunities Fund | Microcap Company Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Micro-Cap Company Stock Risk. The securities of micro-cap companies may be particularly volatile in price, and such securities have significantly lower trading volumes than small- or mid-cap companies. As a result, the purchase or sale of more than a limited number of shares may affect its market price. Micro-cap companies may have limited markets, financial resources, or product lines, may lack management depth, may be more vulnerable to adverse business or market developments, and may have less publicly available information relative to larger companies.

 

Grandeur Peak Emerging Markets Opportunities Fund | Foreign Securities And Foreign Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Securities and Foreign Markets Risk. Foreign securities are generally more volatile and less liquid than U.S. securities. Further, foreign securities may be subject to additional risks not associated with investment in U.S. securities due to differences in the economic and political environment, the amount of available public information, the degree of market regulation, and financial reporting, accounting and auditing standards, and, in the case of foreign currency-denominated securities, fluctuations in currency exchange rates. In some foreign markets, there may not be protection or legal recourse against failure by other parties to complete transactions or in the event of a default on a debt instrument.

 

Grandeur Peak Emerging Markets Opportunities Fund | Emerging And Frontier Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Emerging and Frontier Markets Risk. In addition to the risks of investing in foreign securities in general, the risks of investing in the securities of companies economically tied, including by domicile, to emerging and frontier market countries include increased political or social instability, economies based on only a few industries, unstable currencies, runaway inflation, highly volatile securities markets, unpredictable shifts in policies relating to foreign investments, lack of protection for investors against parties who fail to complete transactions, and the potential for government seizure of assets or nationalization of companies.

 

Grandeur Peak Emerging Markets Opportunities Fund | Foreign Country Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Country Exposure Risk. The Fund may have exposure to foreign countries as a result of investments in domestic companies with foreign exposure. This includes possible exposure to emerging and frontier countries. To the extent the Fund invests in securities of companies with exposure to foreign markets, including in emerging and frontier countries, such investments would be subject to the same risks as a direct investment in such markets and countries. It also may not be possible for companies to repatriate capital, interest, and other income from a particular foreign country. Such risks may impact the stock valuation of companies with foreign exposure.

 

Grandeur Peak Emerging Markets Opportunities Fund | Region Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Region Risk. Social, political, and economic conditions and changes in regulatory, tax or economic policy in a country or region could significantly affect the market in that country or region. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region might adversely impact the issuers of securities in a different country or region. From time to time, a small number of companies and industries may represent a large portion of the market in a particular country or region.

 

India. The Fund is particularly susceptible to risks related to economic, political, regulatory or other events or conditions affecting issuers in India. Because of the Fund’s exposure to Indian securities, its NAV will be much more sensitive to changes in economic, political and other factors within India than would a fund that invested in a variety of countries. Special risks include, among others, political and legal uncertainty, persistent religious, ethnic and border disputes, greater government control over the economy, currency fluctuations or blockage and the risk of nationalization or expropriation of assets. Uncertainty regarding inflation and currency exchange rates, fiscal policy, credit ratings and the possibility that future harmful political actions will be taken by the Indian government, could negatively impact the Indian economy and securities markets, and thus adversely affect the Fund’s performance.

 

Grandeur Peak Emerging Markets Opportunities Fund | Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Currency Risk. The U.S. dollar value of the Fund’s assets will be affected by foreign currency exchange rates and may be affected by exchange control regulations. A change in the value of any foreign currency will change the U.S. dollar value of the Fund’s assets that are denominated or traded in that country. In addition, the Fund may incur costs in connection with conversions between various currencies.

 

Grandeur Peak Emerging Markets Opportunities Fund | Political And Economic Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Political and Economic Risk. Foreign investments may be subject to heightened political and economic risks, particularly in countries with emerging economies and securities markets, which may have relatively unstable governments and economies based on only a few industries. In some countries, there is the risk that the government could seize or nationalize companies, impose additional withholding taxes on dividends or interest income payable on securities, impose exchange controls or adopt other restrictions that could affect the Fund’s investments.

 

Grandeur Peak Emerging Markets Opportunities Fund | Regulatory Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Regulatory Risk. Foreign companies not publicly traded in the United States are not subject to accounting and financial reporting standards and requirements comparable to those U.S. companies must meet. In addition, there may be less information publicly available about such companies.

 

Grandeur Peak Emerging Markets Opportunities Fund | Sector Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector Exposure Risk. At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a broadly related group of industries within an economic sector. Companies in the same economic sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

 

Grandeur Peak Emerging Markets Opportunities Fund | Consumer Discretionary Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

 

Grandeur Peak Emerging Markets Opportunities Fund | Consumer Staples Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Consumer Staples Sector Risk. The consumer staples sector may be affected by the regulation of various product components and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

 

Grandeur Peak Emerging Markets Opportunities Fund | Technology Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

 

Grandeur Peak Emerging Markets Opportunities Fund | Sector And Geography Weightings Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector and Geography Weightings Risk. Market conditions, interest rates and economic, regulatory, or financial developments could significantly affect all the securities in a single sector or geography. If the Fund invests in only a few sectors or geographies, it may have increased relative exposure to the price movements of those sectors and geographies.

 

Grandeur Peak Emerging Markets Opportunities Fund | Smallcap Company Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Small-Cap Company Stock Risk. Small-cap company stocks may be very sensitive to changing economic conditions and market downturns. Small-cap companies’ earnings and revenues may be less predictable, their share prices may be more volatile, and markets less liquid than companies with larger market capitalizations. There may be less publicly available information about these companies, which can affect the pricing of their shares or the Fund’s ability to dispose of those shares.

 

Grandeur Peak Emerging Markets Opportunities Fund | Midcap Company Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Mid-Cap Company Stock Risk. Mid-cap company stocks may be very sensitive to changing economic conditions and market downturns. Mid-cap companies’ earnings and revenues may be less predictable, their share prices may be more volatile, and markets less liquid than companies with larger market capitalizations. There may be less publicly available information about these companies, which can affect the pricing of their shares or the Fund’s ability to dispose of those shares.

 

Grandeur Peak Emerging Markets Opportunities Fund | Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk. Liquidity risk exists when particular investments of the Fund would be difficult to purchase or sell, possibly preventing the Fund from selling such less liquid securities at an advantageous time or price, or possibly requiring the Fund to dispose of the investment, or other investments, at unfavorable times or prices in order to satisfy its obligations.

 

Grandeur Peak Emerging Markets Opportunities Fund | Managed Portfolio Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Managed Portfolio Risk. The Adviser’s investment strategies or choice of specific securities may be unsuccessful and may cause the Fund to incur losses.

 

Grandeur Peak Emerging Markets Opportunities Fund | Earlystage Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Early-Stage Companies Risk. Early-stage companies may never obtain necessary financing, may rely on untested business plans, may not be successful in developing markets for their products or services, and may remain an insignificant part of their industry, and as such may never be profitable. Stocks of early-stage companies may be less liquid, privately traded, and more volatile and speculative than the securities of larger companies.

 

Grandeur Peak Emerging Markets Opportunities Fund | Initial Public Offerings I P Os Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Initial Public Offerings (IPOs) Risk. IPOs involve a higher degree of risk not normally associated with offerings of more seasoned companies. Companies involved in IPOs generally have limited operating histories and their prospects for future profitability are uncertain. Prices of IPOs may also be unstable due to such factors as the absence of a prior public market, the small number of shares available for trading and limited investor information.

 

Grandeur Peak Emerging Markets Opportunities Fund | Growth Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Growth Stock Risk. Growth stock prices may be more sensitive to changes in current or expected earnings than the prices of other stocks, and they may fall or not appreciate in step with the broader securities markets.

 

Grandeur Peak Emerging Markets Opportunities Fund | Value Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Value Investing Risk. Value investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth and is subject to the risk that the stocks’ intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued may actually be appropriately priced.

 

Grandeur Peak Emerging Markets Opportunities Fund | Adr Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

ADR Risk. ADRs involve risks similar to those associated with investments in foreign securities. ADRs listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Investments in ADRs that provide exposure to non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. Investments in ADRs also may be subject to withholding or other taxes and may be indirectly subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

 

Grandeur Peak Emerging Markets Opportunities Fund | Foreign Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Tax Risk. The Fund’s income from foreign issuers may be subject to non-U.S. withholding taxes. A Fund may also be subject to taxes on trading profits or on transfers of securities in some countries.

possible for companies to repatriate capital, interest, and other income from a particular foreign country. Such risks may impact the stock valuation of companies with foreign exposure.

Risk [Text Block]

Region Risk. Social, political, and economic conditions and changes in regulatory, tax or economic policy in a country or region could significantly affect the market in that country or region. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region might adversely impact the issuers of securities in a different country or region. From time to time, a small number of companies and industries may represent a large portion of the market in a particular country or region.

ADR Risk. ADRs involve risks similar to those associated with investments in foreign securities. ADRs listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Investments in ADRs that provide exposure to non-U.S. securities involve certain risks

that may not be present with investments in U.S. securities. Investments in ADRs also may be subject to withholding or other taxes and may be indirectly subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

Grandeur Peak Global Micro Cap Fund | Market And Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for

inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, tariffs and trade wars, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.

 

Grandeur Peak Global Micro Cap Fund | Stock Market Risk [Member]

Stock Market Risk. The Fund’s investments may decline due to movements in the overall stock market. Factors such as domestic and foreign economic growth and market conditions, interest rate levels, political events, natural disasters and the spread of infectious illness or other public health issues affect the securities and derivatives markets. Particularly during periods of declining or illiquid markets, the Fund may experience periods of heavy redemptions that could cause the Fund to liquidate its assets at inopportune times or at a loss or depressed value and could cause the remaining shareholders in the Fund to lose money.

Prospectus [Line Items]  
Risk [Text Block]

Micro-Cap Company Stock Risk. The securities of micro-cap companies may be particularly volatile in price, and such securities have significantly lower trading volumes than small- or mid-cap companies. As a result, the purchase or sale of more than a limited number of shares may affect its market price. Micro-cap companies may have limited markets, financial resources, or product lines, may lack management depth, may be more vulnerable to adverse business or market developments, and may have less publicly available information relative to larger companies.

 

Grandeur Peak Global Micro Cap Fund | Foreign Securities And Foreign Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Securities and Foreign Markets Risk. Foreign securities are generally more volatile and less liquid than U.S. securities. Further, foreign securities may be subject to additional risks not associated with investment in U.S. securities due to differences in the economic and political environment, the amount of available public information, the degree of market regulation, and financial reporting, accounting and auditing standards, and, in the case of foreign currency-denominated securities, fluctuations in currency exchange rates. In some foreign markets, there may not be protection or legal recourse against failure by other parties to complete transactions or in the event of a default on a debt instrument.

 

Grandeur Peak Global Micro Cap Fund | Emerging And Frontier Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Emerging and Frontier Markets Risk. In addition to the risks of investing in foreign securities in general, the risks of investing in the securities of companies economically tied, including by domicile, to emerging and frontier market countries include increased political or social instability, economies based on only a few industries, unstable currencies, runaway inflation, highly volatile securities markets, unpredictable shifts in policies relating to foreign investments, lack of protection for investors against parties who fail to complete transactions, and the potential for government seizure of assets or nationalization of companies.

 

Grandeur Peak Global Micro Cap Fund | Foreign Country Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Country Exposure Risk. The Fund may have exposure to foreign countries as a result of investments in domestic companies with foreign exposure. This includes possible exposure to emerging and frontier countries. To the extent the Fund invests in securities of companies with exposure to foreign markets, including in emerging and frontier countries, such investments would be subject to the same risks as a direct investment in such markets and countries. It also may not be possible for companies to repatriate capital, interest, and other income from a particular foreign country. Such risks may impact the stock valuation of companies with foreign exposure.

 

Grandeur Peak Global Micro Cap Fund | Region Risk [Member]

Region Risk. Social, political, and economic conditions and changes in regulatory, tax or economic policy in a country or region could significantly affect the market in that country or region. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region might adversely impact the issuers of securities in a different country or region. From time to time, a small number of companies and industries may represent a large portion of the market in a particular country or region.

 

Japan. The Fund’s performance may be influenced by political, social and economic factors affecting Japan. From the late 1990’s, Japan’s economic growth rate has remained relatively low compared to that of its Asian neighbors and other major developed economies. The economy is characterized by an aging demographic, a declining population, a large government debt and a highly regulated labor market. Economic growth is dependent on domestic consumption, deregulation and consistent government policy. The Japanese economy is more dependent on international trade than the United States, and may be adversely affected by trade tariffs, other protectionist measures, competition from emerging economies, and the economic conditions of its trading partners. Japan has a growing economic relationship with China and other Southeast Asian countries, and economic, political or social instability in those countries, whether resulting from country, regional or global events, could have an adverse effect on Japan’s economy. The Japanese yen has fluctuated widely at times, and any

material increase in its value may cause a decline in exports that could weaken the Japanese economy. Some of these factors, as well as other adverse political developments, increases in government debt, changes to fiscal, monetary or trade policies, and natural disasters, may affect Japanese markets and the Fund’s performance.

Risk [Text Block]

Early-Stage Companies Risk. Early-stage companies may never obtain necessary financing, may rely on untested business plans, may not be successful in developing markets for their products or services, and may remain an insignificant part of their industry, and as such may never be profitable.

Risk [Text Block]

Initial Public Offerings (IPOs) Risk. IPOs involve a higher degree of risk not normally associated with offerings of more seasoned companies. Companies involved in IPOs generally have limited operating histories and their prospects for future profitability are uncertain. Prices of IPOs may also be unstable due to such factors as the absence of a prior public market, the small number of shares available for trading and limited investor information.

Value Investing Risk. Value investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth, and is subject to the risk that the stocks’ intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued may actually be appropriately priced.

Risk [Text Block]

ADR Risk. ADRs involve risks similar to those associated with investments in foreign securities. ADRs listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Investments in ADRs that provide exposure to non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. Investments in ADRs also may be subject to withholding or other taxes and may be indirectly subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

Prospectus [Line Items]  
Risk [Text Block]

Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies involved in this sector rely to a significant extent on government demand for their products and services.

The Fund is subject to the following principal investment risks:

 

Grandeur Peak Global Reach Fund | Market And Geopolitical Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, tariffs and trade wars, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.

 

Grandeur Peak Global Reach Fund | Stock Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Stock Market Risk. The Fund’s investments may decline due to movements in the overall stock market. Factors such as domestic and foreign economic growth and market conditions, interest rate levels, political events, natural disasters and the spread of infectious illness or other public health issues affect the securities and derivatives markets. Particularly during periods of declining or illiquid markets, the Fund may experience periods of heavy redemptions that could cause the Fund to liquidate its assets at inopportune times or at a loss or depressed value and could cause the remaining shareholders in the Fund to lose money.

 

Grandeur Peak Global Reach Fund | Stock Selection Risk [Member]

Grandeur Peak Global Reach Fund | Microcap Company Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Micro-Cap Company Stock Risk. The securities of micro-cap companies may be particularly volatile in price, and such securities have significantly lower trading volumes than small- or mid-cap companies. As a result, the purchase or sale of more than a limited number of shares may affect its market price. Micro-cap companies may have limited markets, financial resources, or product lines, may lack management depth, may be more vulnerable to adverse business or market developments, and may have less publicly available information relative to larger companies.

 

Grandeur Peak Global Reach Fund | Foreign Securities And Foreign Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Securities and Foreign Markets Risk. Foreign securities are generally more volatile and less liquid than U.S. securities. Further, foreign securities may be subject to additional risks not associated with investment in U.S. securities due to differences in the economic and political environment, the amount of available public information, the degree of market regulation, and financial reporting, accounting and auditing standards, and, in the case of foreign currency-denominated securities, fluctuations in currency exchange rates. In some foreign markets, there may not be protection or legal recourse against failure by other parties to complete transactions or in the event of a default on a debt instrument.

 

Grandeur Peak Global Reach Fund | Emerging And Frontier Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Emerging and Frontier Markets Risk. In addition to the risks of investing in foreign securities in general, the risks of investing in the securities of companies economically tied, including by domicile, to emerging and frontier market countries include increased political or social instability, economies based on only a few industries, unstable currencies, runaway inflation, highly volatile securities markets, unpredictable shifts in policies relating to foreign investments, lack of protection for investors against parties who fail to complete transactions, and the potential for government seizure of assets or nationalization of companies.

 

Grandeur Peak Global Reach Fund | Foreign Country Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Country Exposure Risk. The Fund may have exposure to foreign countries as a result of investments in domestic companies with foreign exposure. This includes possible exposure to emerging and frontier countries. To the extent the Fund invests in securities of companies with exposure to foreign markets, including in emerging and frontier countries, such investments would be subject to the same risks as a direct investment in such markets and countries. It also may not be possible for companies to repatriate capital, interest, and other income from a particular foreign country. Such risks may impact the stock valuation of companies with foreign exposure.

 

Grandeur Peak Global Reach Fund | Region Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Region Risk. Social, political, and economic conditions and changes in regulatory, tax or economic policy in a country or region could significantly affect the market in that country or region. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region might adversely impact the issuers of securities in a different country or region. From time to time, a small number of companies and industries may represent a large portion of the market in a particular country or region.

 

Grandeur Peak Global Reach Fund | Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Currency Risk. The U.S. dollar value of the Fund’s assets will be affected by foreign currency exchange rates and may be affected by exchange control regulations. A change in the value of any foreign currency will change the U.S. dollar value of the Fund’s assets that are denominated or traded in that country. In addition, the Fund may incur costs in connection with conversions between various currencies.

 

Grandeur Peak Global Reach Fund | Political And Economic Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Political and Economic Risk. Foreign investments may be subject to heightened political and economic risks, particularly in countries with emerging economies and securities markets, which may have relatively unstable governments and economies based on only a few industries. In some countries, there is the risk that the government could seize or nationalize companies, impose additional withholding taxes on dividends or interest income payable on securities, impose exchange controls or adopt other restrictions that could affect the Fund’s investments.

 

Grandeur Peak Global Reach Fund | Regulatory Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Regulatory Risk. Foreign companies not publicly traded in the United States are not subject to accounting and financial reporting standards and requirements comparable to those U.S. companies must meet. In addition, there may be less information publicly available about such companies.

 

Grandeur Peak Global Reach Fund | Sector Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector Exposure Risk. At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a broadly related group of industries within an economic sector. Companies in the same economic sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

 

Grandeur Peak Global Reach Fund | Technology Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

 

Grandeur Peak Global Reach Fund | Sector And Geography Weightings Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector and Geography Weightings Risk. Market conditions, interest rates and economic, regulatory, or financial developments could significantly affect all the securities in a single sector or geography.

Risk [Text Block]

Small-Cap Company Stock Risk. Small-cap company stocks may be very sensitive to changing economic conditions and market downturns. Small-cap companies’ earnings and revenues may be less predictable, their share prices may be more volatile, and markets less liquid than companies with larger market capitalizations.

Liquidity Risk. Liquidity risk exists when particular investments of the Fund would be difficult to purchase or sell, possibly preventing the Fund from selling such less liquid securities at an advantageous time or price, or possibly requiring the Fund to dispose of the investment, or other investments at unfavorable times or prices in order to satisfy its obligations.

Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, tariffs and trade wars, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.

Risk [Text Block]

Micro-Cap Company Stock Risk. The securities of micro-cap companies may be particularly volatile in price, and such securities have significantly lower trading volumes than small- or mid-cap companies. As a result, the purchase or sale of more than a limited number of shares may affect its market price. Micro-cap companies may have limited markets, financial resources, or product lines, may lack management depth, and may be more vulnerable to adverse business or market developments, and may have less publicly available information relative to larger companies.

Foreign Securities and Foreign Markets Risk. Foreign securities are generally more volatile and less liquid than U.S. securities. Further, foreign securities may be subject to additional risks not associated with investment in U.S. securities due to differences in the economic and political environment, the amount of available public information, the degree of market regulation, and financial reporting, accounting and auditing standards, and, in the case of foreign currency-denominated securities, fluctuations in currency exchange rates. In some foreign markets, there may not be protection or legal recourse, or in the event of a default on a debt instrument.

Foreign Country Exposure Risk. The Fund may have exposure to foreign countries as a result of investments in domestic companies with foreign exposure. This includes possible exposure to emerging and frontier countries. To the extent the Fund invests in securities of companies with exposure to foreign markets, including in emerging and frontier countries, such

Region Risk. Social, political, and economic conditions and changes in regulatory, tax or economic policy in a country or region could significantly affect the market in that country or region. In addition, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region might adversely impact the issuers of securities in a different country or region. From time to time, a small number of companies and industries may represent a large portion of the market in a particular country or region.

Sector Exposure Risk. At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a broadly related group of industries within an economic sector.

Risk [Text Block]

ADR Risk. ADRs involve risks similar to those associated with investments in foreign securities. ADRs listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Investments in ADRs that provide exposure to non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. Investments in ADRs also may be subject to withholding or other taxes and may be indirectly subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

Sector Exposure Risk. At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a broadly related group of industries within an economic sector. Companies in the same economic sector may be similarly affected by economic or market events, making the Fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Value Investing Risk.

Risk [Text Block]

ADR Risk. ADRs involve risks similar to those associated with investments in foreign securities. ADRs listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares. Investments in ADRs that provide exposure to non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. Investments in ADRs also may be subject to withholding or other taxes and may be indirectly subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

Risk [Text Block]

Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies involved in this sector rely to a significant extent on government demand for their products and services.

Prospectus [Line Items]  
Risk [Text Block]

Market and Geopolitical Risk. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, tariffs and trade wars, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.

 

Grandeur Peak US Stalwarts Fund | Stock Market Risk [Member]

Stock Market Risk. The Fund’s investments may decline due to movements in the overall stock market. Factors such as domestic and foreign economic growth and market conditions, interest rate levels, political events, natural disasters and the spread of infectious illness or other public health issues affect the securities and derivatives markets. Particularly during periods of declining or illiquid markets, the Fund may experience periods of heavy redemptions that could cause the Fund to liquidate its assets at inopportune times or at a loss or depressed value and could cause the remaining shareholders in the Fund to lose money.

Prospectus [Line Items]  
Risk [Text Block]

Foreign Securities and Foreign Markets Risk. Foreign securities are generally more volatile and less liquid than U.S. securities. Further, foreign securities may be subject to additional risks not associated with investment in U.S. securities due to differences in the economic and political environment, the amount of available public information, the degree of market regulation, and financial reporting, accounting and auditing standards, and, in the case of foreign currency-denominated securities, fluctuations in currency exchange rates. In some foreign markets, there may not be protection or legal recourse against failure by other parties to complete transactions or in the event of a default on a debt instrument.

Risk [Text Block]

Foreign Country Exposure Risk. The Fund may have exposure to foreign countries as a result of investments in domestic companies with foreign exposure. This includes possible exposure to emerging and frontier countries. To the extent the Fund invests in securities of companies with exposure to foreign markets, including in emerging and frontier countries, such investments would be subject to the same risks as a direct investment in such markets and countries. It also may not be possible for companies to repatriate capital, interest, and other income from a particular foreign country. Such risks may impact the stock valuation of companies with foreign exposure.

In addition, the Fund may incur costs in connection with conversions between various currencies.

Political and Economic Risk.

In some countries, there is the risk that the government could seize or nationalize

 

companies, impose additional withholding taxes on dividends or interest income payable on securities, impose exchange controls or adopt other restrictions that could affect the Fund’s investments.
