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.

Portfolio turnover is based on the lesser of long-term purchases or sales divided by the average long-term fair value during a period. The Fund did not invest in any long-term securities during the most recent fiscal year. As a result, the Fund’s portfolio turnover rate for the Fund’s most recent fiscal year is not provided.

Expenses Deferred Charges [Text Block]

However, the Fund assesses a contingent deferred sales charge (‘‘CDSC’’) of 0.50% on certain purchases of $1,000,000 or more of A Class shares that are redeemed in whole or part within 18 months of purchase.

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 also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same, except that this Example reflects the fee waiver/expense reimbursement arrangement for A Class and R5 Class shares through April 30, 2027.  C Class shares automatically convert to A Class shares 8 years after purchase, if the conversion is available through your financial intermediary. This Example reflects your costs as though C Class shares were held for the full 10-year period. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Expense Example, With Redemption [Table]

Share Class	1 Year	3 Years	5 Years	10 Years
A	$713	$1,052	$1,414	$2,429
C	$332	$715	$1,225	$2,626
Y	$130	$406	$702	$1,545

Investor	$165	$511	$881	$1,922

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 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 313% of the average value of its portfolio.
