Management's Discussion of Fund Performance
The performance of Class A shares for the period presented is shown in the Average Annual Total Returns table.
Top Performance Contributors
Credit quality security selection
| Positive contribution to benchmark-relative performance was driven by security selection in AAA, AA and BBB rated bonds.
Sector security selection
| Strong sector security selection in local general obligation (GO) and hospital bonds contributed to the Fund’s performance relative to its benchmark.
Credit quality allocation
| Underweight to AAA bonds added to relative performance.
Sector allocation
| An underweight to the state GO bonds added to the Fund’s relative performance.
Top Performance Detractors
Yield curve positioning
 
I
 
Heavy
supply and market
uncertainty
resulted in a reshaping of the yield curve, driving the curve steeper as short rates declined and intermediate and long rates moved higher. The Fund’s yield curve positioning was the main detractor from performance, relative to its benchmark. Specifically, the Fund’s overweight to longer maturity bonds (20 years and longer) and underweight to the shorter end of the curve detracted, as municipal market interest rates saw a material increase on the long end of the curve.
Credit quality allocation
| Overweights to not-rated and BB bonds detracted from relative performance.
Sector allocation
| Overweights to charter schools and continuing care retirement communities (CCRCs) detracted.
Sector security selection
| Security selection in housing bonds detracted from relative performance.

Specifically, the Fund’s overweight to longer maturity bonds (20 years and longer) and underweight to the shorter end of the curve detracted, as municipal market interest rates saw a material increase on the long end of the curve.
Credit quality allocation
| Overweights to not-rated and BB bonds detracted from relative performance.
Sector allocation
| Overweights to charter schools and continuing care retirement communities (CCRCs) detracted.
Sector security selection
| Security selection in housing bonds detracted from relative performance.
