Thornburg California Limited Term Municipal Fund
All income earned by Thornburg California Limited Term Municipal Fund (the “Fund”) during 2007 was based on investments in municipal obligations of political subdivisions located in the state of California, or on investments in obligations of U.S. territories and possessions which bear interest exempt from taxation by the state of California. Generally speaking, distributions made by the Fund to individuals are not subject to federal income taxes, but they must be reported on your 2007 federal income tax return. However, a small portion of this income, as shown below, may be treated as a preference item for the purposes of the alternative minimum tax on certain individuals and on corporations. Shareholders are advised to consult their own tax advisors as to the extent and effect of such treatment.
The Fund did not declare capital gains distributions in 2007.

The principal value of bond funds will fluctuate relative to changes in interest rates; decreasing when interest rates rise. Unlike bonds, bond funds have ongoing fees and expenses.
