In September, 2006, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 157, "Fair Valuation
Measurements" ("FAS 157"). This standard clarifies the definition of fair value
for financial reporting, establishes a framework for measuring fair value and
requires additional disclosures about the use of fair value measurements. FAS
157 establishes three different categories for valuations. Level 1 valuations
are those based upon quoted prices in active markets. Level 2 valuations are
those based upon quoted prices in inactive markets or based upon significant
observable inputs (i.e. yield curves; benchmark interest rates; indices). Level
3 valuations are those based upon unobservable inputs (i.e. discounted cash flow
analysis; non-market based methods used to determine fair valuation). Details of
the valuations as of August 31, 2008 were as follows:

Subsequent to August 31, 2008, the major U.S. and global equity market
benchmarks posted sharp declines. From August 31, 2008 through October 15, 2008,
the Dow Jones Industrial Average lost 29.0%, the S&P 500 Index declined by 25.5%
and the Nasdaq Composite shed 31.2%. Globally, the MSCI World Index declined
23.8% and the MSCI EAFE lost 24.2%.

As illustrated by the benchmark returns, the impact was not limited to a
specific sector. The Chicago Board of Options Exchange Volatility Index, which
is generally used as a gauge of fear and uncertainty in the market place,
reached levels never seen before. The markets appeared to have lost confidence
in the financial system after a significant series of events which included: the
government rescue of mortgage entities Fannie Mae and Freddie Mac, the failure
of investment bank Lehman Brothers, the merger of Merrill Lynch with Bank of
America, the government bailout of American International Group, and the passage
of a $700 billion financial rescue package designed to help rid financial
institutions of "toxic" debt carried on their books. The combination of these
events, and others, resulted in significant declines in market valuations of the
impacted securities, the financials sector in general and the broad market as a
whole.



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 in 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.
