Item 2 - Controls and Procedures

2(a) - The registrant's certifying officers have reasonably designed such
       disclosure controls and procedures to ensure material information
       relating to the registrant is made known to us by others particularly
       during the period in which this report is being prepared. The
       registrant's certifying officers have determined that the registrant's
       disclosure controls and procedures are effective based on our evaluation
       of these controls and procedures as of a date within 90 days prior to the
       filing date of this report.

2(b) - As of September 29, 2006, with the conclusion of the combination of
       Merrill Lynch's asset management business with BlackRock, the registrant
       was migrated to BlackRock's trading and compliance monitoring systems,
       and various personnel changes occurred. In conjunction with these
       business improvements, there were no changes in the registrants internal
       control over financial reporting (as defined in Rule 30a-3(d) under Act
       (17 CFR 270.30a-3(d)) that occurred during the last fiscal half-year of
       the period covered by this report that has materially affected, or is
       reasonably likely to affect, the registrant's internal control over
       financial reporting.
