Any additional investments made by a shareholder after September 19, 2008 in excess of the amount held on that date will not be covered. The Fund will bear the expenses of participating in the Guarantee Program and any subsequent extensions. Further information about the Guarantee Program can be obtained at www.ustreas.gov.
