ITEM 2.	CONTROLS AND PROCEDURES

	(a) The Chief Executive and Financial Officers concluded that the Registrant’s Disclosure Controls and Procedures are effective based on the evaluation of the Disclosure Controls and Procedures as of a date within 90 days of the filing date of this report. Management of the Registrant has determined that as of and prior to December 31, 2006, the Registrant's first fiscal quarter end, the Registrant had a material weakness in its internal control over financial reporting related to the review, analysis and determination of whether certain transfers of municipal securities qualified for sale accounting under the provisions of Statement of Financial Accounting Standards No. 140. Since December 31, 2006, but prior to the date of this filing, management has revised its internal control over financial reporting to improve the effectiveness of the controls to ensure that transactions in transfers of municipal securities are accounted for properly. Management notes that other investment companies investing in similar investments over the same time periods had been accounting for such investments in a similar manner as the Registrant. Accordingly, other investment companies are also concluding that there was a material weakness in their internal control over financial reporting of such investments.

	(b) There have been no changes in the Registrant's internal control over financial reporting that occurred during the Registrant’s first fiscal quarter covered by this report that have materially affected, or are reasonably likely to materially affect, the Registrant's internal control over financial reporting. However, as discussed above, subsequent to December 31, 2006, the Registrant's internal control over financial reporting was enhanced.
