The Index is designed to measure the U.S. dollar-denominated, high yield (junk), fixed-rate, taxable corporate bond market.

Bonds are classified as high yield if the middle rating of Moody's, Fitch and S&P is Ba1/BB+/BB+ or below.

The fund’s sub-adviser, Insight North America LLC, an affiliate of the Adviser, uses a systematic investment process to select high yield securities for the fund’s portfolio. The sub-adviser uses a proprietary credit model to construct a portfolio with general risk characteristics (e.g., credit rating distribution, duration and sector weightings) similar to those of the Index. The sub-adviser also uses the proprietary credit model to determine appropriate weightings, based on risk and relative value signals, of individual securities for the fund’s portfolio in an attempt to generate a modest amount of outperformance over the Index. For example, the sub-adviser may overweight against the Index individual securities identified by the credit model to have more favorable risk and relative value signals and may underweight against the Index individual securities identified by the credit model to have less favorable risk and relative value signals. The sub-adviser will seek to ensure that the fund’s exposure to securities identified with less favorable risk and relative value signals, if any, will be no greater than such securities’ weights in the Index at the time of purchase. Current fund portfolio holdings may become sell candidates if the sub-adviser believes that bonds with better risk and return characteristics become available, or if the holding no longer meets the sub-adviser's strategic or portfolio construction objectives. The fund may, from time to time, invest a significant portion (more than 20%) of its assets in securities of companies in certain sectors and/or industries. As of March 31, 2024, 20.6% of the fund's portfolio consisted of securities of Consumer Cyclical companies, although this may change from time to time. The fund is classified as diversified under the Investment Company Act of 1940, as amended (1940 Act).

The fund’s sub-adviser, Insight North America LLC, an affiliate of the Adviser, uses a systematic investment process to select high yield securities for the fund’s portfolio. The sub-adviser uses a proprietary credit model to construct a portfolio with general risk characteristics (e.g., credit rating distribution, duration and sector weightings) similar to those of the Index.

The fund may, from time to time, invest a significant portion (more than 20%) of its assets in securities of companies in certain sectors and/or industries. As of March 31, 2024, 20.6% of the fund's portfolio consisted of securities of Consumer Cyclical companies, although this may change from time to time.
