Material Fund Change [Text Block]
How has the Fund changed?
  • On December 5, 2025, BNY Mellon Income Stock Fund (“Predecessor Fund”), a series of BNY Mellon Funds Trust, was reorganized into the Fund (“Reorganization”). The Fund commenced operations upon completion of the Reorganization and continues the operations of the Predecessor Fund. Prior to the Reorganization, the Predecessor Fund’s Class A, Class C, Class I, Class Y, and Investor shares redesignated into Class M shares. In addition, the Predecessor Fund’s Class M shares effected a reverse share split to approximate the net asset value per share of the Fund prior to the Reorganization. Prior to the Reorganization, the Predecessor Fund discontinued the imposition of distribution fees, which had previously been paid to BNY Mellon Securities Corporation, the Predecessor Fund’s distributor (“Distributor”), at an annual rate of .75% of the value of Class C shares based on average daily net assets. The Predecessor Fund also discontinued the imposition of shareholder services fees, which had previously been paid to the Distributor at an annual rate of .25% of the value of each of the Predecessor Fund’s Investor, Class A and Class C shares based on average daily net assets. At the time of the Reorganization, the expense limitation agreement with the Predecessor Fund’s investment adviser was discontinued.

Factors Affecting Performance [Text Block]
How did the Fund perform last year ?
  • For the 12-month period ended August 31, 2026, the Fund’s shares returned 0.99% on a net asset value basis and 0.78% on a market price basis.
  • In comparison, the Bloomberg U.S. Aggregate Bond Index (the “Index”) returned 1.89% for the same period.
What affected the Fund’s performance?
  • Despite higher interest rates, bond markets delivered positive total returns. Risk assets also performed well, supported by a strong labor market and a favorable domestic economic outlook.
  • The strongest contributors to the Fund’s performance relative to the Index included overweight allocations to corporate bonds, emerging markets, asset-backed securities and non-agency mortgage-backed securities.
  • Within the corporate bond sector, overweight positions in high yield, banks, utilities and finance companies were beneficial, as was security selection favoring non-traditional asset-backed securities sectors and collateralized loan obligations.
  • Interest rate positioning detracted from relative performance throughout the period, as inflation failed to moderate meaningfully and front-end interest rates remained stubbornly high.
  • Overweight exposure to agency mortgage-backed securities and underweight exposure to commercial mortgage-backed securities also detracted, as did security selection within taxable municipals.
