Expense Example [Heading] oef_ExpenseExampleHeading Example.
Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock

The following example is intended to help you compare the cost of investing in the shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The fee waiver/expense reimbursement arrangement included in the table above is reflected only through October 31, 2026.

Portfolio Turnover [Heading] oef_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] oef_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 its most recent fiscal year, the Fund’s portfolio turnover rate was 13% of the average value of its portfolio.

Portfolio Turnover, Rate oef_PortfolioTurnoverRate 13.00%
Strategy [Heading] oef_StrategyHeading Principal Investment Strategy.
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of its net assets in the equity securities of infrastructure companies. Equity securities in which the Fund invests as part of its principal investment strategy consist of common stocks, stapled securities (an equity security comprised of multiple parts) and Real Estate Investment Trusts (“REITs”) of infrastructure companies. The Fund will concentrate in the infrastructure sector and utilities industry. The Fund will invest in both U.S. and non-U.S. companies of all market capitalizations, with a minimum market capitalization of U.S. $500 million at the time of investment. With respect to its non-U.S. investments, the Fund invests in companies located in developed countries but may also invest in emerging markets as part of its principal investment strategy.

 

The Fund’s subadviser, Magellan Asset Management Limited doing business as Magellan Investment Partners (formerly MFG Asset Management) (“Magellan Investment Partners”), seeks to provide investors with exposure to the infrastructure sector and to deliver stable investment returns relative to other equity funds. The Fund invests in a diversified portfolio of securities of infrastructure companies that Magellan Investment Partners has determined have an appropriate capital structure, are likely to generate reliable income streams and are likely to benefit from inflation protection. The Fund’s portfolio will typically comprise 70-100 securities.

Risk [Text Block] oef_RiskTextBlock

Market Risks; Recent Market Events. The Fund’s investments are subject to market risk, which may cause the value of the Fund’s investments to decline. If the value of the Fund’s investments goes down, the share price of the Fund will go down, and you may lose money. U.S. and international markets have experienced volatility in recent months and years due to a number of economic, political and other global macro factors, including elevated inflation levels, trade tensions, tariffs and the ongoing wars in Europe and the Middle East. Uncertainties regarding the future of the Federal Reserve’s monetary policy, political events, rising government debt in the U.S. and the possibility of a national or global recession have also contributed to market volatility. During periods of volatility, the Fund may experience high levels of shareholder redemptions and may have to sell securities at times when the Fund would otherwise not do so, potentially at unfavorable prices. Certain securities may be difficult to value during such periods.

REIT Risks. A REIT’s share price may decline because of adverse developments affecting the underlying industry, including changes to interest rates. The returns of REITs may trail returns of the overall market. The Fund’s investments in REITs may be subject to special tax rules, or a particular REIT may fail to qualify for the favorable federal income tax treatment applicable to REITs, the effect of which may have adverse tax consequences for the Fund and shareholders. Changes in tax laws may also result in unfavorable tax treatment of REITs. The Fund will indirectly bear its proportionate share of expenses incurred by REITs in which the Fund invests in addition to the expenses incurred directly by the Fund.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Shareholder Ownership and Concentration Risks. A large percentage of the Fund’s shares are held by financial intermediaries and institutional investors. In many cases, the Fund does not have visibility as to the underlying beneficial owners of the Fund’s shares. A large redemption by one or more of these shareholders could result in the Fund selling securities when it otherwise would not have done so, accelerating the realization of capital gains and increasing transaction costs. A large redemption could also significantly reduce the Fund’s assets and increase the Fund’s expenses.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Infrastructure and Utilities Concentration Risks. The Fund’s investments in infrastructure and utilities companies will expose the Fund to potential adverse economic, regulatory, political and other changes affecting such investments. Issuers of securities in infrastructure-related businesses are subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, high leverage, costs associated with environmental or other regulations and the effects of economic slowdowns. Rising interest rates could lead to higher financing costs and reduced earnings for infrastructure companies. Specific infrastructure assets in which the Fund invests may be subject to additional risks relating to communication, energy, social, transportation and utilities infrastructure companies.

Risk [Text Block] oef_RiskTextBlock

Small- and Medium-Capitalization Company Risks. Small-capitalization and medium-capitalization companies are often more volatile and less liquid than larger companies. Securities of these companies may be subject to greater and more abrupt price fluctuations and may be more susceptible to market pressures and business failures. Stocks of small and medium-sized companies may underperform the stocks of larger companies as an asset class.

[1] The “Total Annual Fund Operating Expenses” and “Total Annual Fund Operating Expenses After Fee Waiver/Expense Reimbursement” for Service Class shares do not correlate to the “Ratio of expenses to average net assets” figures in the Financial Highlights section of this Prospectus because Service Class shares accrued shareholder servicing fees in the amount of 0.10% for the fiscal year ended June 30, 2025.
[2] Frontegra Asset Management, Inc. (“Frontegra”), the Fund’s investment adviser, has contractually agreed to waive its management fee and/or reimburse the Fund’s operating expenses to the extent necessary to ensure that the Fund’s total operating expenses (excluding taxes, interest, brokerage commissions, acquired fund fees and expenses (“AFFE”) and extraordinary expenses) do not exceed 0.50% and 0.65% of the Fund’s average daily net assets attributable to the Institutional Class and Service Class shares, respectively. Frontegra is entitled to recoup the fees waived and/or expenses reimbursed within a three-year period from the date of the waiver or expense payment if such reimbursement will not cause the Fund’s expense ratio to exceed the lesser of: (a) the expense limitation in place at the time of the waiver and/or expense payment; or (b) the expense limitation in place at the time of the recoupment. The expense cap/reimbursement agreement will continue in effect until October 31, 2026, and may be terminated only by, or with the consent of, the Board of Directors of the Company.
