Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Key contributors to (↑) and detractors from (↓) performance, relative to the Bloomberg Municipal Bond Index (the Index):

↑ An overweight exposure to BBB- and below-rated bonds contributed to Index-relative returns during the period

↑ An overweight allocation to and security selections in bonds with 4% coupon rates also helped performance

↑ An overweight exposure to bonds with 17-22 years remaining to maturity contributed to Index-relative returns

↓ In contrast, an allocation to variable-rate demand notes, typically considered defensive investments, weighed on performance

↓ An allocation to taxable municipal bonds detracted from Index-relative returns during the period

↓ An underweight exposure to the transportation sector hurt relative performance during the period

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Key contributors to (↑) and detractors from (↓) performance, relative to the Bloomberg Municipal Bond Index (the Index):

↑ An overweight exposure to BBB- and below-rated bonds contributed to the Fund's performance during the period

↑ An overweight exposure to, and security selections in, bonds with 4% coupon rates also contributed to Index-relative returns

↑ An overweight exposure to bonds with 17-22 years remaining to maturity contributed to performance relative to the Index during the period

↓ In contrast, out-of-Index exposures to variable-rate demand notes, typically considered defensive investments, detracted from returns

↓ An out-of-Index allocation to taxable municipal bonds detracted from performance during the period

↓ An underweight exposure to, and security selections in, the water and sewer sector hurt Index-relative returns during the period

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Key contributors to (↑) and detractors from (↓) performance, relative to the Bloomberg Municipal Bond Index (the Index):

↑ An overweight exposure to BBB- and below-rated bonds contributed to the Fund's performance during the period

↑ An overweight exposure to, and security selections in, bonds with 4% coupon rates also contributed to Index-relative returns

↑ An overweight exposure to bonds with 17-22 years remaining to maturity contributed to performance relative to the Index during the period

↓ In contrast, out-of-Index exposures to variable-rate demand notes, typically considered defensive investments, detracted from returns

↓ An out-of-Index allocation to taxable municipal bonds detracted from performance during the period

↓ An underweight exposure to, and security selections in, the water and sewer sector hurt Index-relative returns during the period

Factors Affecting Performance [Text Block]

Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Key contributors to (↑) and detractors from (↓) performance, relative to the Bloomberg Municipal Bond Index (the Index):

↑ An overweight allocation to, and security selections in healthcare/hospital bonds contributed to Index-relative returns during the period

↑ An overweight exposure to, and security selections in bonds with 17 to 22 years to maturity also contributed to performance during the period

↓ In contrast, security selections in bonds with 8-12 years remaining to maturity detracted from the Fund's performance

↓ An allocation to variable-rate demand notes and floating-rate notes — typically considered defensive investments — also detracted from returns

↓ An underweight position in, and security selections in the leasing sector also hurt performance during the period

How did the Fund perform last year and what affected its performance?

Key contributors to (↑) and detractors from (↓) performance, relative to the Bloomberg Municipal Bond Index (the Index):

↓ Out-of-Index exposures to variable-rate demand notes and floating-rate notes, typically considered defensive investments, detracted from returns

↓ An out-of-Index allocation to taxable municipal bonds also detracted during the period

↓ An underweight exposure to the transportation sector hurt returns during the period

How did the Fund perform last year and what affected its performance?

Key contributors to (↑) and detractors from (↓) performance, relative to the Bloomberg Municipal Bond Index (the Index):

↑ An overweight exposure to bonds rated BBB and below contributed to returns during the period

↑ An overweight position and security selections in bonds with 4.00% coupon rates also contributed to performance

↑ An overweight position and security selections in bonds with 22+ years remaining to maturity also contributed to Index-relative returns during the period

↓ Security selections in bonds with 8 to 12 years remaining to maturity detracted from returns during the period

↓ An allocation to variable-rate demand notes and floating-rate notes — typically considered defensive investments — also detracted from returns

↓ An allocation to taxable municipal bonds, which generally underperformed tax-exempt municipal bonds during the period, also detracted
