(1) The Adviser has contractually agreed to waive its investment advisory fees and/or to reimburse expenses of the Fund to the extent necessary to maintain the Total Annual Fund Operating Expenses After Fee Waiver and Expense Reimbursement (excluding brokerage costs, acquired fund fees and expenses, interest, taxes, and extraordinary expenses) at no more than an annual rate of 2.00%, 2.00%, 2.75%, and 1.00% for Class AAA, Class A, Class C, and Class I shares, respectively. Under this same arrangement, the Fund has also agreed, during the two year period following the year of any such waiver or reimbursement by the Adviser, to repay such amount, but only to the extent the Fund’s adjusted Total Annual Fund Operating Expenses would not exceed an annual rate of 2.00%, 2.00%, 2.75%, and 1.00% for Class AAA, Class A, Class C, and Class I shares, respectively, after giving effect to the repayments. This arrangement is in effect through April 30, 2026, and may be terminated only by the Board of Directors of the Fund (the “Board”) before such time. The Fund will carry forward any fees and expenses in excess of the expense limitation and repay the Adviser such amount provided the Fund is able to do so without exceeding the lesser of (1) the expense limit in effect at the time of the waiver or reimbursement, as applicable, or (2) the expense limit in effect at the time of recoupment after giving effect to the repayment.
Expense Example [Heading] Expense Example
Expense Example Narrative [Text Block]

This example is intended to help you compare the cost of investing in 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 assumes a waiver of expenses through the date of the expiration of the waiver, and reflects Total Annual Fund Operating Expenses following the date of the expiration of the waiver. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class AAA Shares     $ 203       $ 762       $ 1,347       $ 2,935  
Class A Shares     $ 766       $ 1,292       $ 1,844       $ 3,340

Portfolio Turnover [Heading] Portfolio Turnover
Portfolio Turnover [Text Block]

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 the Fund’s shares are held in a taxable account. These costs, which are not reflected in the 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 23% of the average value of its portfolio.
