| Portfolio Turnover [Heading] | rr_PortfolioTurnoverHeading | Portfolio Turnover | |||||||||||||
| 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 46% of the average value of its portfolio.

| The Value Fund | Market Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Market Risk: Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in response to changing market conditions, inflation, changes in interest rates, lack of liquidity in the bond or equity markets, volatility in the equity markets, market disruptions caused by local or regional events such as financial institution failures, war, acts of terrorism, the spread of infectious illness (including epidemics and pandemics) or other public health issues, recessions or other events or adverse investor sentiment. There is also a risk that a particular style of investing, such as value, may underperform other styles of investing or the market generally.
|

| The Value Fund | Investment Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Investment Risk: The value of your investment in this Fund may fluctuate, which means that you could lose money. The types of stocks held by the Fund may not perform as well as other types of stocks.

| The Value Fund | Equity Securities Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Equity Securities Risk: Common stockholders participate in company profits through dividends and stock market appreciation and, in the event of bankruptcy, distributions, on a pro-rata basis after other claims are satisfied. Many factors affect the value of common stock, including earnings, earnings forecasts, corporate events and factors impacting the issuer’s industry and the market generally. Common stock generally has the greatest appreciation and depreciation potential of all corporate securities.

|||||||||||||
| The Value Fund | Quantitative Model Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Quantitative Model Risk: Securities selected using quantitative models may perform differently from the market as a whole for many reasons, including the factors used in building the model and the weights placed on each factor, among others. Results generated by such models may be impaired by errors in human judgment, data imprecision, software or other technology system malfunctions. The quantitative model used by the Adviser to manage the Fund may not perform as expected, particularly in volatile market or in a rising interest rate environment.

| The Value Fund | Management Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Management Risk: A strategy used by the Adviser may fail to produce the intended results.

| The Value Fund | Large Cap Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Large-Cap Risk: Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. In addition, larger companies may grow more slowly or be slower to respond to business developments than smaller companies. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. Over certain periods, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.
|
|||||||||||||
| The Value Fund | Mid Cap Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Mid-Cap Risk: Investing in securities of mid-sized companies may be riskier than investing in larger, more established companies. Mid-sized companies are more vulnerable to adverse developments because of more limited product lines, markets or financial resources. Also, these stocks may trade less often and in limited volume compared to larger cap stocks trading on a national securities exchange. The prices of these stocks may be more volatile than the prices of larger company stocks. As a result, the Fund’s net asset value may be subject to rapid and substantial changes.
|
|||||||||||||
| The Value Fund | Issuer Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Issuer Risk: The value of a security owned by the Fund may decline for a reason directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or services.
|
|||||||||||||
| The Value Fund | Sector Concentration Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Sector Concentration Risk: Although the Fund will not concentrate in any particular industry, it may be heavily invested in a particular economic sector. If the Fund focuses on one or a few sectors, its performance is likely to be disproportionately affected by developments that significantly affect that sector, including market, economic, political or regulatory developments. Individual sectors may be more volatile and may perform differently than the broader market. The Fund’s performance may also suffer if a sector does not perform as well as the Adviser expected. Prices of securities in the same sector often change collectively regardless of the merits of individual companies.

| The Value Fund | Health Care Sector Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Health Care Sector Risk: Factors such as extensive government regulation, restrictions on government reimbursement for medical expenses, rising costs of medical products, services and facilities, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, costs associated with obtaining and protecting patents, product liability and other claims, changes in technologies and other market developments can affect companies in the health care sector.

|||||||||||||
| The Value Fund | Large Shareholder Purchase and Redemption Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Large Shareholder Purchase and Redemption Risk: The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell its securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value and liquidity. Similarly, large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

|||||||||||||
| The Value Fund | Cybersecurity Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Cybersecurity Risk: Cybersecurity breaches may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund and/or its service providers to suffer data corruption or lose operational functionality.
|
|||||||||||||
| The Value Fund | Value Investing Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Value Investing Risk: The Fund emphasizes a value style of investing that focuses on undervalued companies with characteristics for improved valuation. As a result, the Fund is subject to greater risk that the market may not recognize a security’s inherent value for a long time, or a stock judged to be undervalued by the Adviser may actually be appropriately priced or overvalued. Value oriented funds will typically underperform when growth investing is in favor.
|
|||||||||||||
| The Value Fund | Financials Sector Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Financials Sector Risk: The Fund’s performance may be adversely affected by events affecting the financials sector, if it invests a relatively large percentage of its assets in this sector. The financials sector can be significantly affected by changes in interest rates, government regulation, the rate of corporate and consumer debt defaulted, price competition, and the availability and cost of capital. Events affecting the financials sector have had, and may continue to have, a significant negative impact on the valuations and stock prices of companies in this sector and have increased the volatility of investments in this sector.

|||||||||||||
| The Value Fund | Energy Sector Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Energy Sector Risk: Changes in worldwide energy prices, exploration and production spending may adversely affect companies in the energy sector. In addition, changes in government regulation, world events and political and economic conditions can affect these companies. These companies also are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism, war and natural disasters. Commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, development of alternative energy sources, technological developments, geopolitical conflict and related economic sanctions and labor relations also could affect companies in this sector.

| The Value Fund | Industrials Sector Risk [Member] | |||||||||||||||
| Risk/Return: | rr_RiskReturnAbstract | ||||||||||||||
| Risk [Text Block] | rr_RiskTextBlock | Industrials Sector Risk: Changes in government regulation, world events and economic conditions may adversely affect companies in the industrials sector.

Commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, technological developments and labor relations could adversely affect the companies in this sector.
