Municipal bond (muni) yields tracked Treasury yields higher, but munis generally outperformed Treasuries. Favorable supply/demand dynamics and credit fundamentals and attractive tax-exempt yield levels broadly supported positive returns for the period. California munis generally underperformed national municipal bonds. High-yield munis outperformed investment-grade munis, which aided fund performance, given the fund’s high-yield overweight versus the index.</span></td></tr><tr><td colspan="3" style="padding:0 1pt"><div style="padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial Narrow',sans-serif;font-size:10pt;font-weight:400;line-height:100%">•</span></div></td><td colspan="3" style="padding:1.5pt 1pt;text-align:left;vertical-align:top"><span style="color:#000000;font-family:'Arial Narrow',sans-serif;font-size:10pt;font-weight:400;line-height:100%">Sector allocation drove performance, mostly due to an overweight position versus the index in corporate munis and underweight exposure to industrial development revenue/pollution control revenue bonds.

Municipal bond (muni) yields tracked Treasury yields higher, but munis generally outperformed Treasuries. Favorable supply/demand dynamics and credit fundamentals and attractive tax-exempt yield levels broadly supported positive returns for the period. California munis generally underperformed national municipal bonds. High-yield munis outperformed investment-grade munis, which aided fund performance, given the fund’s high-yield overweight versus the index.</span></td></tr><tr><td colspan="3" style="padding:0 1pt"><div style="padding-left:36pt;text-indent:-18pt"><span style="color:#000000;font-family:'Arial Narrow',sans-serif;font-size:10pt;font-weight:400;line-height:100%">•</span></div></td><td colspan="3" style="padding:1.5pt 1pt;text-align:left;vertical-align:top"><span style="color:#000000;font-family:'Arial Narrow',sans-serif;font-size:10pt;font-weight:400;line-height:100%">Sector allocation drove performance, mostly due to an overweight position versus the index in corporate munis and underweight exposure to industrial development revenue/pollution control revenue bonds.
