Risk [Text Block]
  ● Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Mighty Mites Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Mighty Mites Fund’s securities goes down, your investment in the Mighty Mites Fund decreases in value.

Prospectus [Line Items]  
Risk [Text Block]
  ● Small- and Micro-Cap Company Risk. Although small-cap and micro-cap companies may offer greater potential for capital appreciation than larger companies, investing in securities of small-cap and micro-cap companies may involve greater risks than investing in larger, more established issuers. Small-cap and micro-cap companies generally have limited product lines, markets, and financial resources. Their securities may trade less frequently and in more limited volume than the securities of larger, more established companies. Also, small-cap and micro-cap companies are typically subject to greater changes in earnings and business prospects than larger companies. Consequently, small-cap and micro-cap company stock prices tend to rise and fall in value more than other stocks. The risks of investing in micro-cap stocks and companies are even greater than those of investing in small-cap companies.
TETON WESTWOOD MIGHTY MITES FUND | Industrials Risk [Member]

Risk [Text Block]
  ● Industrials Risk. Industrials companies are engaged in the manufacture and distribution of capital goods, such as those used in defense, construction and engineering, companies that manufacture and distribute electrical equipment and industrial machinery and those that provide commercial and transportation services and supplies. Industrials companies may be adversely affected by changes in government regulation, world events and economic conditions. In addition, companies in the industrials sector may be adversely affected by environmental damages, product liability claims and exchange rates.

  ● Consumer Discretionary Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences and tastes, social trends, marketing campaigns and introduction of new consumer products.

 

TETON WESTWOOD MIGHTY MITES FUND | Foreign Securities Risk [Member]

  ● Foreign Securities Risk. Investments in foreign securities involve risks relating to political, social, and economic developments abroad, as well as risks resulting from the differences between the regulations to which U.S. and foreign issuers and markets are subject. These risks include expropriation, differing accounting and disclosure standards, currency exchange risks, settlement difficulties, market illiquidity, difficulties enforcing legal rights, and greater transaction costs. These risks are more pronounced in the securities of companies located in emerging markets.

● Geopolitical Risk. Occurrence of global events, such as war, terrorist attacks, natural disasters, country instability, infectious disease epidemics, pandemics and other public health issues, market instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers and other governmental trade or market control programs, the potential exit of a country from its respective union and related geopolitical events, may result in market volatility and may have long-lasting impacts on both the U.S. and global financial markets. For example, the U.S. government has imposed, and may in the future further increase, tariffs on certain foreign goods, and some foreign governments have instituted retaliatory tariffs on certain U.S. goods. These and any further actions that may be taken by the U.S. and foreign governments with respect to trade policy may impair the value of your investment in the Fund.

Risk [Text Block]

You may want to invest in the Fund if:

 

  ● you are a long-term investor

 

  ● you seek growth of capital

 

  ● you seek investments in small capitalization growth stocks as part of your overall investment strategy

 

The Small Cap Fund’s share price will fluctuate with changes in the market value of the Small Cap Fund’s portfolio securities. An investment in the Fund is not a deposit of the bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell Small Cap Fund shares, they may be worth more or less than what you paid for them; you may lose money by investing in the Fund.

 

Investing in the Small Cap Fund involves the following risks:

 

Keeley Small Cap Fund | Information Technology Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Information Technology Risk. Information technology companies may have limited product lines, markets financial resources or personnel. Information technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights. Companies in the information technology sector are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

 

Keeley Small Cap Fund | Financial Services Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Financial Services Risk. The Small Cap Fund may invest from time to time in securities issued by financial services companies. Financial services companies can be significantly affected by changing economic conditions, demand for consumer loans, refinancing activity and intense competition, including price competition. Profitability can be largely dependent on the availability and cost of capital and the rate of consumer debt defaults, and can fluctuate significantly when interest rates change; unstable and/or rising interest rates may have a disproportionate effect on companies in the financial services sector. Financial services companies are subject to extensive government regulation, which can change frequently and may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain, or may affect them in other ways that are unforeseeable. In the past, financial services companies in general experienced considerable financial distress, which led to the implementation of government programs designed to ease that distress.

 

Keeley Small Cap Fund | Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Sector Risk. Although the Fund does not employ a sector focus, its exposure, from time to time, to specific sectors will increase based on the Small Cap Adviser’s perception of available investment opportunities. If the Fund focuses on a particular sector, the Fund may face an increased risk that the value of its portfolio will decrease because of events disproportionately affecting that sector. Furthermore, investments in particular sectors may be more volatile than the broader market as a whole.

TETON Convertible Securities Fund | Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
● Sector Risk. Although the Fund does not employ a sector focus, the percentage of the Fund’s assets invested in a particular sector can increase from time to time based on the Adviser’s perception of available investment opportunities. If the Fund invests a significant portion of its assets in a particular sector, the Fund will be subject to the risk that companies in the same sector are likely to react similarly to legislative or regulatory changes, adverse market conditions, increased competition, or other factors affecting that market segment. In such cases, the Fund
  would be exposed to an increased risk that the value of its overall portfolio will decrease because of events that disproportionately and negatively affect that sector. In addition, investments in a particular sector may be more volatile than the broader market as a whole, and the Fund’s investments in such a sector may be disproportionately susceptible to losses.

 

TETON Convertible Securities Fund | Convertible Securities Risk [Member]

Risk [Text Block]
  ● Convertible Securities Risk. Convertible securities provide higher yields than the underlying common stock, but generally offer lower yields than nonconvertible securities of similar quality. The value of convertible securities fluctuates in relation to changes in interest rates and, in addition, fluctuates in relation to the underlying common stock.

 

TETON Convertible Securities Fund | Information Technology Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Information Technology Risks. The information technology sector includes companies engaged in developing software and providing data processing and outsourced services, along with manufacturing and distributing communications equipment, computers and other electronic equipment and instruments, and semiconductors and semiconductor equipment manufacturers. Information technology companies are particularly vulnerable to federal, state and local government regulation, and competition and consolidation, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies also face competition for services of qualified personnel. Additionally, information technology companies face rapid technological development and frequent new product introduction by competitors. Information technology companies typically rely on patents and intellectual property rights.
TETON Convertible Securities Fund | Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Credit Risk. The Convertible Securities Fund’s investments are subject to the risk that issuers and/or counterparties will fail to make payments when due or default completely. Prices of the Convertible Securities Fund’s investments may be adversely affected if any of the issuers or counterparties it is invested in are subject to an actual or perceived deterioration in their credit quality. Credit spreads may increase, which may reduce the market values of the Convertible Securities Fund’s securities. Credit spread risk is the risk that economic and market conditions or any actual or perceived credit deterioration may lead to an increase in the credit spreads (i.e., the difference in yield between two securities of similar maturity but different credit quality) and a decline in price of the issuer’s securities.

 

TETON Convertible Securities Fund | High Yield Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● High Yield Securities Risk. The Convertible Securities Fund may invest in higher yielding, lower rated bonds, commonly called “junk bonds”. Bonds that are rated Ba or below by Moody’s, or BB or below by S&P or Fitch, or if unrated, determined by the Gabelli Sub-Adviser to be of comparable quality, are generally considered to be high yield bonds. These high yield bonds are subject to greater risks than lower yielding, higher rated debt securities. As a result, the Convertible Securities Fund may experience losses associated with its holdings of high yield securities.

 

TETON Convertible Securities Fund | Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  ● Interest Rate Risk. The Convertible Securities Fund’s investments in fixed income securities will change in value based on changes in interest rates. If rates increase, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value. The Convertible Securities Fund may invest in variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Convertible Securities Fund may be subject to heightened interest rate risk as a result of changes in economic conditions, inflation and government monetary policy, such as changes in the federal funds rate. There is no way of predicting the frequency or quantum of potential interest rate changes.

  ● Small-Cap Company Risk. Although small-cap companies may offer greater potential for capital appreciation than larger companies, investing in securities of small-cap companies may involve greater risks than investing in larger, more established issuers. Small-cap companies generally have limited product lines, markets, and financial resources. Their securities may trade less frequently and in more limited volume than the securities of larger, more established companies. Also, small-cap companies are typically subject to greater changes in earnings and business prospects than larger companies. Consequently, small-cap company stock prices tend to rise and fall in value more than other stocks.

Prospectus [Line Items]  
Risk [Text Block]
  ● Large Cap Risk. Large cap risk is the risk that stocks of larger companies may underperform relative to those of small and mid-sized companies. Large cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

Risk [Text Block]
  ● Pre-Payment Risk. The Balanced Fund may experience losses when an issuer exercises its right to pay principal on an obligation held by the Balanced Fund (such as a mortgage-backed security) earlier than expected. This may happen during a period of declining interest rates. Under these circumstances, the Balanced Fund may be unable to recoup all of its initial investment and will suffer from having to invest in lower yielding securities. The loss of higher yielding securities and the reinvestment at lower interest rates can reduce the Balanced Fund’s income, total return, and share price.
