Performance shown prior to the inception date is that of the predecessor fund’s Class A shares at net asset value and includes the 12b-1 fees applicable to that class. Although invested in the same portfolio of securities, Class R5 shares’ returns of the Fund will be different from Class A shares’ returns of the predecessor fund as they have different expenses.
2
The “Custom Invesco Senior Floating Rate Index” reflects the performance of the Credit Suisse Leveraged Loan Index through September 30, 2014 and the J.P. Morgan Leveraged Loan Index from October 1, 2014.
3
Effective December 15, 2023, the Fund changed its broad-based securities market benchmark from the JP Morgan Leveraged Loan Index to the Bloomberg U.S. Aggregate Bond Index to reflect that the Bloomberg U.S. Aggregate Bond Index can be considered more broadly representative of the overall applicable securities market.
After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements, such as 401(k) plans, 529 college savings plans or individual retirement accounts. After-tax returns are shown for Class A shares only and after-tax returns for other classes will vary.
