2005 U.S. Government Income/Intangible Property

A percentage of your ordinary dividends from the interest you earned on U.S. Government securities may be exempt from taxes. See below for more information, and consult your tax advisor for information specific to your tax situation.

U.S. Government income - 2005

In most states, mutual fund dividends from interest on direct U.S. Government securities are exempt from state and local taxes. To find out if you qualify for this exemption based on your state laws, consult your tax advisor or check your state or local tax instruction booklet. Some states only exempt dividends for those funds holding a minimum percentage, usually 50%, of government securities at the end of each quarter (see the fourth column in the table below.)

To determine the amount that may be eligible for each of your funds, multiply the percent of income attributable to direct U.S. Government securities (shown in the second column in the table below) by the amount for that fund in Box 1a of your IRS Form 1099-DIV.

Intangible property - 2005

If you pay state intangible property tax on the value of your open-end or closed-end mutual fund, you may be able to exempt a percentage of the fund's investments held in U.S. Government securities. To determine this percentage, multiply the percent of fund held in U.S. Government securities at December 31, 2005 (shown in third column of the table below) by the value of your shares at year-end.

If you are a resident of Florida, no portion of the value of the funds below is exempt from the Florida intangible tax on December 31, 2005.
