Overview
Investment Strategy
This Fund offers New Mexico investors double tax-free yields (income is exempt from regular federal and New Mexico state income taxes but may be subject to alternative minimum tax) in a laddered municipal bond portfolio with an average maturity of three to ten years. Investments with shorter average maturities, such as the Thornburg New Mexico Intermediate Municipal Fund, are less exposed to interest rate risk than investments with longer average maturities.
Fund Objective
Obtain as high a level of current income exempt from federal and New Mexico state individual income taxes as is consistent, in the view of the Fund's investment advisor, with preservation of capital. A secondary objective is to reduce expected changes in its share price relative to long-term bond portfolios.
There is no guarantee that the Fund will meet its investment objectives. A portion of the Fund's dividends could be subject to the federal Alternative Minimum Tax.
Laddered Portfolio Strategy
Laddering involves building a portfolio of bonds with staggered maturities so that a portion of the portfolio will mature each year. To maintain the ladder, cash from maturing bonds is typically invested in bonds with longer maturities at the far end of the ladder. The strategy is a good compromise for managing different types of risk. Read More...

Lipper ratings for Preservation reflect the funds’ historical loss avoidance relative to other funds within the fixed income asset class. The ratings are subject to change every month and are based on an equal-weighted average of percentile ranks for the Preservation metric over three-, five-, and ten-year periods (if applicable). The highest 20% of funds in each peer group are named Lipper Leader, or a score of 5, for Preservation, the next 20% receive a score of 4, the middle 20% are scored 3, the next 20% are scored 2, and the lowest 20% are scored 1. Preservation ratings are relative, rather than absolute, measures, and funds named Lipper Leaders for Preservation may still experience losses periodically; those losses may be larger for equity and mixed equity funds than for fixed income funds. Lipper ratings are not intended to predict future results, and Lipper does not guarantee the accuracy of this information. More information is available at www.lipperweb.com.

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. We have used ratings from Standard & Poor’s (S&P). Where S&P ratings are not available, we have used Moody’s Investors Service. Where neither rating is available, we have used ratings from Fitch Ratings. “NR” = not rated.
