Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio).  A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when 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 4.79% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund seeks to meet its objective by investing its assets in:

•  
U.S. government securities including U.S. Treasury obligations and obligations issued or guaranteed by U.S. government agencies or instrumentalities;

•  
investment grade corporate bonds;

•  
investment grade foreign government bonds;

•  
equity securities of medium capitalization (between $2 billion and $7 billion) and large capitalization ($7 billion and above) North American companies;

•  
American Depositary Receipts (ADRs);

•  
certificates of deposit; and

•  
other investment companies such as the Schemes of the Trinidad and Tobago Unit Trust Corporation, which are separate investment companies created by the Unit Trust Corporation of Trinidad and Tobago Act of 1981, and money market funds.

Under normal market conditions, the Fund will maintain a level of at least 80% of its total assets invested in the types of debt and equity securities identified above of companies domiciled in North America.  The term “North America” includes Mexico, the United States, Canada, Greenland, Central America and the independent nations in the Caribbean Sea, including Trinidad and Tobago.

Regarding the debt securities portion of the portfolio, the Fund invests primarily in fixed income securities of North American corporate issuers that are rated investment grade or better (namely, rated in one of the four highest rating categories by a nationally recognized statistical rating organization (NRSRO)) or determined to be of comparable quality by the Fund’s portfolio managers, debt securities of non-U.S. governments that are rated investment grade or better or determined to be of comparable quality by the Fund’s portfolio managers, and U.S. government securities.

Regarding the equity securities portion of the portfolio, the Fund invests in equity securities of North American companies, including common stocks, preferred stocks, and convertible securities.   The Fund may also invest in ADRs and securities of foreign companies.  ADRs are equity securities trading on U.S. exchanges that are generally issued by banks or trust companies to evidence ownership of foreign equity securities.

The Fund selects equity securities of companies that the Fund’s portfolio managers believe are undervalued based on the current price relative to the long-term prospects of the company.  The Fund’s portfolio managers also consider a company’s actual and prospective earnings, return on equity and assets to liabilities ratio when selecting stocks.

The Fund, in response to adverse market, economic, political or other conditions, may take a temporary defensive position.  The Fund will sell a security if its portfolio manager believes a company’s fundamentals will deteriorate or if it believes a company’s stock has little potential for further appreciation.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
The Fund is a suitable investment for investors with long-term investment goals.  Like all mutual funds, investing in the Fund involves certain risks, which may cause you to lose money.  These risks include:

•  
Stock Market Risk:  Funds that hold equity securities are subject to stock market risks and significant fluctuations in value.  If the stock market declines in value, the Fund is likely to decline in value.  The Fund’s focus on medium to large capitalization stocks and value-style of investing subject it to the risk that its performance may be lower than that of other types of funds with equity portfolios that focus on other types of stocks (such as small capitalization stocks) or that have a broader investment style (such as growth or general market).  The Fund is also subject to the risk that medium to large capitalization and/or value stocks may under-perform other segments of the equity market or the equity market as a whole.  In general, the prices of the securities in which the Fund invests may decline for a number of reasons.  The price declines of common stocks may be steep, sudden and/or prolonged.

•  
Securities Selection Risk:  The portfolio securities held by the Fund may decline in value or not increase in value when the market in general is rising and may fail to meet the Fund’s investment objective.

•  
Interest Rate Risk:  In general, the value of bonds and other debt securities rises when interest rates fall and falls when interest rates rise.  Longer term obligations are usually more sensitive to interest rate changes than shorter term obligations.  While bonds and other debt securities normally fluctuate less in price than do common stocks, there have been extended periods of increases in interest rates that have caused significant declines in bond prices.

•  
Credit Risk:  The Fund may invest in debt securities not backed by the full faith and credit of the United States.  The issuers of such bonds and other debt securities may not be able to make interest or principal payments.  Even if these issuers are able to make interest or principal payments, they may suffer adverse changes in financial condition that would lower the credit quality of the issuer, leading to greater volatility in the price of the security.

•  
Prepayment Risk:  The issuers of bonds and other debt securities held by the Fund may prepay the principal due on such securities, particularly during periods of declining interest rates.  Securities subject to prepayment risk generally offer less potential for gain when interest rates decline, and may offer a greater potential for loss when interest rates rise.  Rising interest rates may cause prepayments to occur at a slower than expected rate.  This will increase the average life of the security and make the security more sensitive to interest rate changes.

•  
Small Capitalization Risk:  Though the Fund’s focus is on medium to large capitalization stocks, the Fund may invest in small capitalization stocks.  Small companies often have narrower product lines and markets and more limited managerial and financial resources, and as a result may be more sensitive to changing economic conditions. Stocks of small companies are often more volatile and tend to have less trading volume than those of large companies.  Less trading volume may make it more difficult to sell securities of small companies at quoted market prices.  Finally, there are periods when investing in small capitalization company stocks falls out of favor with investors and the stocks of small companies underperform.

•  
Foreign Investment Risks:  These are risks associated with investing in foreign securities that are in addition to the risks associated with investing in U.S. securities.

•  
Foreign Political and Economic Risks:  The degree of political and economic stability varies from country to country.  If a country confiscates money from foreigners or takes over an industry, the Fund may lose some or all of any particular investment in that country.  Parts of individual foreign economies may vary favorably or unfavorably from the U.S. economy (for example, inflation rate), which may affect the value of the Fund’s investment in any foreign country.

•  
Foreign Investment Expense Risk:  Investing in foreign securities generally costs more than investing in U.S. securities because of higher transaction costs, such as the commissions paid per share.  As a result, mutual funds that invest in foreign securities tend to have higher expenses due to higher commissions and higher advisory and custodial fees.

•  
Currency Risk:  Foreign currency risk is the risk that the U.S. dollar value of foreign securities held by the Fund may be affected favorably or unfavorably by changes in foreign currency exchange rates and exchange control regulations.  The value of the Fund may go up and down as the value of the dollar rises and falls compared to a foreign currency.

•  
Governmental Regulation Risk:  Many foreign countries do not subject their markets to the same degree and type of laws and regulations that cover the U.S. markets.  Also, many foreign governments impose restrictions on investments as well as taxes or other restrictions on repatriation of investment income.  The regulatory differences in some foreign countries make investing or trading in their markets more difficult and risky.

•  
Corporate Disclosure Standard Risk:  Many countries have laws making information on publicly traded companies, banks and governments more difficult to obtain, incomplete or unavailable.  The lack of uniform accounting standards and practices among countries impairs the ability of investors to compare common valuation measures, such as price/earnings ratios, for securities of different countries.

•  
Liquidity Risk:  Foreign markets or exchanges tend to have less trading volume than the New York Stock Exchange or other domestic stock exchanges or markets, which means that the foreign market may have less liquidity.  Lower liquidity in a foreign market can affect the Fund’s ability to purchase or sell blocks of securities and obtain the best price in the foreign market.  This may cause the Fund to lose opportunities for favorable purchases or sales of investments.  Because foreign markets trade at times and on days different than U.S. markets, the Fund’s value may change when an investor’s account cannot be accessed.
