GAAP requires disclosure of fair valuation measurements as of each measurement
date. In compliance with GAAP, the Fund follows a fair value hierarchy that
distinguishes between market data obtained from independent sources (observable
inputs) and the Fund's own market assumptions (unobservable inputs). These
inputs are used in determining the value of the Fund's investments and
summarized in the following fair value hierarchy:

Level 1 - quoted prices in active markets for identical securities.

Level 2 - quoted prices in inactive markets or other significant observable
inputs (e.g. quoted prices for similar securities; interest rates; prepayment
speed; credit risk; yield curves)

Level 3 - significant unobservable inputs (e.g. discounted cash flow analysis;
non-market based methods used to determine fair value)

Observable inputs are those based upon market data obtained from independent
sources, and unobservable inputs reflect the fund's own assumptions based on the
best information available. The various input levels are not an indication of
the risk associated with investing in those securities.

The following table represents the Fund's investments carried on the Statement
of Assets and Liabilities by caption and by level within the fair value
hierarchy as of January 31, 2010:

ITEM 2.  CONTROLS AND PROCEDURES.

     (a) The registrant's principal executive officer and principal financial
         officer have evaluated the registrant's disclosure controls and
         procedures (as defined in Rule 30a-3(c) under the Investment Company
         Act of 1940, as amended) as of a date within 90 days of the filing date
         of this report and have concluded, based on such evaluation, that the
         registrant's disclosure controls and procedures were effective, as of
         that date, in ensuring that information required to be disclosed by the
         registrant on this Form N-Q was recorded, processed, summarized and
         reported within the time periods specified in the Securities and
         Exchange Commission's rules and forms.

     (b) There was no change in the registrant's internal control over financial
         reporting (as defined in Rule 30a-3(d) under the Investment Company Act
         of 1940, as amended) that occurred during the registrant's last fiscal
         quarter that has materially affected or is reasonably likely to
         materially affect the registrant's internal control over financial
         reporting.

ITEM 3.  EXHIBITS.

     A separate certification for each principal executive officer and principal
financial officer of the registrant as required by Rule 30a-2(a) under the
Investment Company Act of 1940, as amended (17 CFR 270.30a-2(a)), is attached
hereto.
