Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div>Conversely, holdings within health care lagged. Returns from consumer staples and financials sectors, though positive, were lower than the overall portfolio’s return. <img alt="Fund Performance - Growth of 10K" src="chartimages_1598472.jpg" style="width: 550pt;"/> <div style="margin-top: 0;

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.

Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.</div><div style="margin-top: 0; margin-right: 0; margin-bottom: 4.0032pt; margin-left: 0; font-size: 9pt; font-weight: normal; color: rgb(0, 0, 0); font-family: 'Arial'; line-height: 11pt; letter-spacing: -0.04pt;">Conversely, holdings within health care lagged.
