b The Federal Housing Finance Agency ("FHFA") placed Federal Home Loan Mortgage Corporation and Federal National Mortgage
Association into conservatorship with FHFA as the conservator. As such, the FHFA oversees the continuing affairs of these
companies.

At October 31, 2012, the cost of investments for federal income tax purposes was substantially the same as the cost for financial
reporting purposes.

The Financial Accounting Standards Board (“FASB”) Accounting
Standards Codification (“ASC”) is the exclusive reference of
authoritative U.S. generally accepted accounting principles (“GAAP”)
recognized by the FASB to be applied by nongovernmental entities.
Rules and interpretive releases of the Securities and Exchange
Commission (“SEC”) under authority of federal laws are also sources
of authoritative GAAP for SEC registrants. The fund's
financial statements are prepared in accordance with GAAP, which
may require the use of management estimates and assumptions. Actual
results could differ from those estimates.

Portfolio valuation: Investments in securities are valued at amortized
cost in accordance with Rule 2a-7 under the Act. If amortized cost is
determined not to approximate market value, the fair value of the portfolio
securities will be determined by procedures established by and under
the general supervision of the Board of Trustees.
The fair value of a financial instrument is the amount that would be
received to sell an asset or paid to transfer a liability in an orderly transaction
between market participants at the measurement date (i.e. the
exit price). GAAP establishes a fair value hierarchy that prioritizes the
inputs of valuation techniques used to measure fair value. This hierarchy
gives the highest priority to unadjusted quoted prices in active
markets for identical assets or liabilities (Level 1 measurements) and the
lowest priority to unobservable inputs (Level 3 measurements).
Additionally, GAAP provides guidance on determining whether the
volume and activity in a market has decreased significantly and
whether such a decrease in activity results in transactions that are not
orderly. GAAP requires enhanced disclosures around valuation inputs
and techniques used during annual and interim periods.
Various inputs are used in determining the value of the fund’s investments
relating to fair value measurements. These inputs are summarized
in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for
identical investments.
Level 2—other significant observable inputs (including quoted
prices for similar investments, interest rates, prepayment speeds,
credit risk, etc.).
Level 3—significant unobservable inputs (including the fund’s
own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily
an indication of the risk associated with investing in those
securities. For example, money market securities are valued using
amortized cost, in accordance with rules under the Act. Generally,
amortized cost approximates the current fair value of a security, but
since the value is not obtained from a quoted price in an active market,
such securities are reflected as Level 2.

The fund may enter into repurchase agreements with financial institutions, deemed to be creditworthy by the Manager, subject to
the seller’s agreement to repurchase and the fund’s agreement to resell such securities at a mutually agreed upon price. Pursuant to
the terms of the repurchase agreement, such securities must have an aggregate market value greater than or equal to the terms of the
repurchase price plus accrued interest at all times. If the value of the underlying securities falls below the value of the repurchase
price plus accrued interest, the fund will require the seller to deposit additional collateral by the next business day. If the request for
additional collateral is not met, or the seller defaults on its repurchase obligation, the fund maintains its right to sell the underlying
securities at market value and may claim any resulting loss against the seller.

Additional investment related disclosures are hereby incorporated by reference to the annual
and semi-annual reports previously filed with the Securities and Exchange Commission on Form N-CSR.

At October 31, 2012, the cost of investments for federal income tax purposes was substantially the same as the cost for financial
reporting purposes.

Portfolio valuation: Investments in securities are valued at amortized
cost in accordance with Rule 2a-7 under the Act. If amortized cost is
determined not to approximate market value, the fair value of the portfolio
securities will be determined by procedures established by and under
the general supervision of the Board of Trustees.
The fair value of a financial instrument is the amount that would be
received to sell an asset or paid to transfer a liability in an orderly transaction
between market participants at the measurement date (i.e. the
exit price). GAAP establishes a fair value hierarchy that prioritizes the
inputs of valuation techniques used to measure fair value. This hierarchy
gives the highest priority to unadjusted quoted prices in active

markets for identical assets or liabilities (Level 1 measurements) and the
lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the
volume and activity in a market has decreased significantly and
whether such a decrease in activity results in transactions that are not
orderly. GAAP requires enhanced disclosures around valuation inputs
and techniques used during annual and interim periods.
Various inputs are used in determining the value of the fund’s investments
relating to fair value measurements. These inputs are summarized
in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for

identical investments.
Level 2—other significant observable inputs (including quoted
prices for similar investments, interest rates, prepayment speeds,
credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s
own assumptions in determining the fair value of investments).
