How did the Fund perform last year?
For the reporting period ended December 31, 2024, the Fund's Institutional Shares returned 5.14%.
For the same period, the Bloomberg U.S. Aggregate Bond Index returned 1.25% and the Customized Reference Benchmark, a blend of 70% Bloomberg U.S. Aggregate Bond Index and 30% S&P 500 Index, returned 7.98%.
What contributed to performance?
Given the positive returns across the financial markets in 2024, most segments of the portfolio contributed to absolute returns. Holdings in floating-rate securities, including both collateralized loan obligations and bank loans, made the largest contribution at a time of rising interest rates and tightening spreads on credit-oriented investments. U.S. equities further helped absolute returns, as did investment-grade corporate bonds. Allocations to high yield bonds, cash, mortgage-backed securities, preferred stocks, emerging-market bonds, emerging-market stocks, and infrastructure stocks also made smaller, but nonetheless positive, contributions.
The Fund held derivatives during the year. Its use of covered calls (intended as an alternative source of income) and currency management strategies both aided performance. It also used U.S. equity derivatives (futures and options) to manage overall risk levels, which did not have a material impact on results.
The Fund’s cash position was modestly elevated at the end of the period given attractive yields and the investment adviser’s desire to have cash available to deploy if asset prices decline. The cash position contributed to absolute returns.
What detracted from performance?
The Portfolio’s exposure to rate-sensitive assets such as U.S. Treasuries and Euro bunds, which it achieved in part through the use of derivatives, detracted from absolute performance. International developed-market equities also detracted due to the impact of individual security selection. A position in international developed-market REITs, which are rate sensitive, detracted marginally.

Footnote(d) | For purposes of this report, credit quality ratings shown above reflect the highest rating assigned by either S&P Global Ratings or Moody’s Investors Service, Inc. if ratings differ. These rating agencies are independent, nationally recognized statistical rating organizations and are widely used. Investment grade ratings are credit ratings of BBB/Baa or higher. Below investment grade ratings are credit ratings of BB/Ba or lower. Investments designated N/R are not rated by either rating agency. Unrated investments do not necessarily indicate low credit quality. Credit quality ratings are subject to change. |
Footnote(e) | The investment adviser evaluates the credit quality of unrated investments based upon certain factors including, but not limited to, credit ratings for similar investments and financial analysis of sectors, individual investments and/or issuers. Using this approach, the investment adviser has deemed unrated U.S. Government Sponsored Agency Securities and U.S. Treasury Obligations to be of similar credit quality as investments rated AAA/Aaa. |

For the same period, the Bloomberg U.S. Aggregate Bond Index returned 1.25% and the Customized Reference Benchmark, a blend of 70% Bloomberg U.S. Aggregate Bond Index and 30% S&P 500 Index, returned 7.98%.

Householding
The Fund will mail only one copy of shareholder documents, including prospectuses, annual and semi-annual reports and proxy statements, to shareholders with multiple accounts at the same address. This practice is commonly called “householding” and is intended to reduce expenses and eliminate duplicate mailings of shareholder documents. Mailings of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your household, please call the Fund at (800) 441-7762.

What were the Fund costs for the last year?
(based on a hypothetical $10,000 investment)
Class name | Costs of a $10,000 investment | Costs paid as a percentage of a $10,000 investment |
|---|---|---|
Investor C Shares | $ |
How did the Fund perform last year?
For the reporting period ended December 31, 2024, the Fund's Investor C Shares returned 4.11%.
For the same period, the Bloomberg U.S. Aggregate Bond Index returned 1.25% and the Customized Reference Benchmark, a blend of 70% Bloomberg U.S. Aggregate Bond Index and 30% S&P 500 Index, returned 7.98%.
What contributed to performance?
Given the positive returns across the financial markets in 2024, most segments of the portfolio contributed to absolute returns. Holdings in floating-rate securities, including both collateralized loan obligations and bank loans, made the largest contribution at a time of rising interest rates and tightening spreads on credit-oriented investments. U.S. equities further helped absolute returns, as did investment-grade corporate bonds. Allocations to high yield bonds, cash, mortgage-backed securities, preferred stocks, emerging-market bonds, emerging-market stocks, and infrastructure stocks also made smaller, but nonetheless positive, contributions.
The Fund held derivatives during the year. Its use of covered calls (intended as an alternative source of income) and currency management strategies both aided performance. It also used U.S. equity derivatives (futures and options) to manage overall risk levels, which did not have a material impact on results.
The Fund’s cash position was modestly elevated at the end of the period given attractive yields and the investment adviser’s desire to have cash available to deploy if asset prices decline. The cash position contributed to absolute returns.
What detracted from performance?
The Portfolio’s exposure to rate-sensitive assets such as U.S. Treasuries and Euro bunds, which it achieved in part through the use of derivatives, detracted from absolute performance. International developed-market equities also detracted due to the impact of individual security selection. A position in international developed-market REITs, which are rate sensitive, detracted marginally.

| Footnote | Description |
Footnote(a) | Excludes short-term securities. |
Footnote(b) | Ten largest investment types are presented. Additional investment types are found in Other. |
Footnote(c) | Rounds to less than 0.1%. |
Footnote(d) | For purposes of this report, credit quality ratings shown above reflect the highest rating assigned by either S&P Global Ratings or Moody’s Investors Service, Inc. if ratings differ. These rating agencies are independent, nationally recognized statistical rating organizations and are widely used. Investment grade ratings are credit ratings of BBB/Baa or higher. Below investment grade ratings are credit ratings of BB/Ba or lower. Investments designated N/R are not rated by either rating agency. Unrated investments do not necessarily indicate low credit quality. Credit quality ratings are subject to change. |
Footnote(e) | The investment adviser evaluates the credit quality of unrated investments based upon certain factors including, but not limited to, credit ratings for similar investments and financial analysis of sectors, individual investments and/or issuers. Using this approach, the investment adviser has deemed unrated U.S. Government Sponsored Agency Securities and U.S. Treasury Obligations to be of similar credit quality as investments rated AAA/Aaa. |

Householding
The Fund will mail only one copy of shareholder documents, including prospectuses, annual and semi-annual reports and proxy statements, to shareholders with multiple accounts at the same address. This practice is commonly called “householding” and is intended to reduce expenses and eliminate duplicate mailings of shareholder documents. Mailings of your shareholder documents may be householded indefinitely unless you instruct us otherwise. If you do not want the mailing of these documents to be combined with those for other members of your household, please call the Fund at (800) 441-7762.
The Fund is not sponsored, endorsed, issued, sold, or promoted by Bloomberg Index Services Limited, S&P Dow Jones Indices, and their respective affiliates, nor do these companies make any representation regarding the advisability of investing in the Fund.
