MINO primarily invests in US municipal bonds, which are bonds exempt from federal taxes. The fund will generally hold investment grade securities but may also allocate up to 30% of the fund in high-yield securities. Private activity bonds may also be included in the portfolio. These exposures push the fund into a broader category, allowing for a wider reach than other funds in the same segment. MINO will select bonds that will potentially offer attractive current income by looking for bonds that can provide consistently attractive current yields or that are priced competitively. The fund aims for an average portfolio duration of 2 years within the portfolio duration of the benchmark index
