Overview

Why Invest in This Fund?

Actively managed diversified portfolio of high-quality municipal bonds with an average duration of no more than three years.
Proven bottom-up fundamental approach that incorporates a top-down macroeconomic overlay to identify what we perceive to be the most attractive opportunities on a relative value basis across geographic regions, sectors, issuers and revenue streams.
Income-seeking fund that aims for a stable net asset value, making it attractive for those with a short investment horizon, and is positioned to quickly take advantage of any increases in short-term interest rates.

Investment Objective

The fund’s goal is to provide investors with current income exempt from federal income tax, consistent with preservation of capital.

Investment Approach

The fund is an actively managed diversified portfolio of municipal bonds. To reduce changes in its share value compared to longer duration fixed income portfolios, the fund normally maintains an average duration of no more than three years. The management team seeks to match municipal market structure and deal flow through a relative value framework that operates across geography, sectors, issuers and revenue streams. The strategy maintains exposure across the maturity spectrum to manage duration, hedge against interest rate fluctuations and limit taxable events.

Statement of Additional Information (SAI)

Important Information

This communication is not authorized for distribution to prospective investors in the Fund unless preceded or accompanied by an effective prospectus.

Investments carry risks, including possible loss of principal. Portfolios investing in bonds have the same interest rate, inflation, and credit risks that are associated with the underlying bonds. The value of bonds will fluctuate relative to changes in interest rates, decreasing when interest rates rise. Unlike bonds, bond funds have ongoing fees and expenses. Investments in the Fund are not FDIC insured, nor are they bank deposits or guaranteed by a bank or any other entity.

Credit quality ratings use the highest rating available from either S&P Global Ratings or Moody's Investors Service. Where neither rating is available, we have used ratings from other nationally recognized statistical rating organizations (NRSROs).

A bond credit rating assesses the financial ability of a debt issuer to make timely payments of principal and interest. Ratings of AAA (the highest), AA, A, and BBB are investment-grade quality. Ratings of BB, B, CCC, CC, C and D (the lowest) are considered below investment grade, speculative grade, or junk bonds.

Diversification does not assure or guarantee better performance and cannot eliminate the risk of investment losses.

Income earned from municipal bonds is exempt from regular federal and in some cases, state and local income tax. Income may be subject to the alternative minimum tax (AMT).

Class I shares may not be available to all investors. Minimum investments for the I share class may be higher than those for other classes.

There is no guarantee that the Fund will meet its investment objectives.

To determine a fund's Morningstar Rating™, funds and other managed products with at least a three-year history are ranked in their categories by their Morningstar Risk-Adjusted Return scores. The top 10% receive 5 stars; the next 22.5%, 4 stars; the middle 35%, 3 stars; the next 22.5%, 2 stars; and the bottom 10% receive 1 star. The Risk-Adjusted Return accounts for variation in a managed product's monthly excess performance (excluding sales charges), placing more emphasis on downward variations and rewarding consistent performance. Other share classes may have different performance characteristics.
