Prospectus [Line Items]
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 Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.
General Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.
Behavioral Strategy Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Behavioral Strategy Risk. When taking investment positions, FullerThaler will apply principles based on behavioral finance. In order to take advantage of behavioral biases, FullerThaler generally focuses on certain markers of possible under and overreaction by investors. Securities identified using this type of strategy may perform differently from the market for various reasons, including the criteria used in the analysis, the weight placed on each criterion, and changes in the criterion’s historical trends. The criteria used in implementing this strategy and the weight placed on those criteria may not be predictive of a security’s value, and the effectiveness of the criteria can change over time. These changes may not be reflected in the current analytical approach used to implement the behavioral strategy. FullerThaler’s strategy based on behavioral finance may be less effective in certain market environments. For example, the Fund invests when FullerThaler believes other investors are over-reacting to significant negative news coverage about a security. As a result, the Fund may experience substantial under-performance during such periods of investor “overreaction,” including as compared to the market overall, the Fund's benchmark and/or to other funds that do not employ a behavioral finance strategy. There can be no guarantee that FullerThaler will be successful in applying behavioral finance principles in managing the Fund.
Smaller Company Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Smaller Company Risk. Investments in securities of smaller companies (mid cap and small cap companies) may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than securities of larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of securities issued by such companies may be more sudden or erratic than the prices of securities of larger companies, especially over the short term. These risks are higher for small cap companies.
Value Investing Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.
Larger Capitalization Company Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Larger Capitalization Company Risk. Although the Fund invests primarily in securities of small cap companies, it may invest in equity investments of larger capitalization companies and, to the extent it does, it may underperform other funds during periods when the Fund's larger capitalization securities are out of favor.
Real Estate Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Real Estate Securities Risk. The Fund’s investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, decreases in real estate values, overbuilding, increased competition and other risks related to local or general economic conditions, increases in operating costs and property taxes, changes in zoning laws, casualty or condemnation losses, possible environmental liabilities, regulatory limitations on rent, possible lack of availability of mortgage financing, market saturation, fluctuations in rental income and the value of underlying properties and extended vacancies of properties, and the management skill and creditworthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.
Industry and Sector Focus Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Industry and Sector Focus Risk. At times, the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, contagion risk within a particular industry or sector or to other industries or sectors, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of the Fund’s shares may fluctuate in response to events affecting that industry or sector. In particular, small capitalization value funds and indices typically have a large weighting in both the financials sector as well as the banking industry. Due to the Fund’s emphasis on small capitalization value stocks, the Fund will typically have a large weighting in the financials sector as well as the banking industry. Developments affecting the financial sector or banking industry may have a significant impact on the value of the Fund’s shares. Those developments may include changes in economic or business conditions, financial markets, government policy and regulations, competition, and interest rates. The Fund may from time to time hold either a larger or smaller weight in the financials sector or banking industry group compared to its benchmark, the Russell 2000® Value Index.
Financials Sector Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Financials Sector Risk. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financials sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.
Materials Sector Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Materials Sector Risk. Companies in the materials sector may be adversely affected by changes in world events, energy conservation, environmental policies, imposition of import controls, increased competition, labor relations, the volatility of commodity prices, changes in exchange rates, social and political unrest, depletion of resources, decreases in demand, over-production, litigation and changes in government regulations, among other factors.
Transactions Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may 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.
Risk Lose Money [Member]
