         f) Each of the individuals listed above is a United States citizen.

ITEM 3   Source and Amount of Funds or Other Considerations

         00  Cash deposited in investment accounts regarding which Sit
             Investment Associates, Inc. its subsidiaries, Sit Investment
             Fixed Income Advisors, Inc. and Sit Fixed Income Advisors II, LLC
             (together "SIA") have investment discretion.

ITEM 4   Purpose of Transaction

         Shares of the Issuer have been acquired and sold over a period of time
         beginning March 11, 1996, and since the filing of the previous
         amendments to this Schedule 13D, in the ordinary course of business as
         an investment manager for investment purposes.

         The shares of the Issuer have been trading at a significant discount
         to net asset value during the past several years. SIA has determined
         that it is in the best interests of certain of its clients to pursue
         with the Issuer changes in the Issuer's practices or policies that, if
         adopted, would tend to reduce or eliminate the discount at which the
         shares of the Issuer will trade in the future.





         SIA otherwise does not seek to influence or control the management of
         the Issuer. SIA will continue to acquire and sell shares of the
         Issuer on behalf of its clients for investment purposes in the
         ordinary course of business and will vote such additionally acquired
         shares in favor of any proposal submitted to shareholders that
         satisfactorily meets the objectives described above.

         Practices that SIA has discussed with management of the Issuer that,
         if adopted, may reduce or eliminate the discount at which the shares
         of the Issuer will trade in the future include: a.) investment
         strategies that may increase the Issuer's income and maintain an
         investment grade quality rating such as utilizing equity based
         leverage; investing in shares of closed-end funds with high returns
         and investment objectives similar to the Issuer's, including funds
         affiliated with the Issuer; and utilizing repurchase agreements on
         agency mortgage securities; b.) policies to re-purchase the Issuer's
         shares such as authorizing a tender offer; and c.) adoption of a
         distribution policy that provides for including in dividends the
         Issuer's principal repayments in addition to interest and other income
         and capital gains (if any), which, if adopted, would constitute a
         return of capital. SIA has also discussed the ability of a closed-end
         fund to initiate a rights offering.

         SIA sent a letter to the management of the Issuer dated January 28,
         1998 proposing changes to the Issuer's practices (the letter was
         attached as an exhibit to Schedule 13D filed on February 28, 1998).
         On March 18, 1998 the management of the Issuer announced that it
         intended to recommend to the Issuer's board of directors that the
         board authorize new discretionary repurchase offers during December
         1999 and December 2001. The Issuer repurchased 10% of its shares at
         net asset value in December 1999, and did not offer to repurchase
         shares in December 2001.

         On July 7, 2009, SIA sent a letter to management of the Issuer
         requesting the adoption of a distribution policy that would include in
         the periodic distributions to the Issuer's shareholders the principal
         payments received on the Issuer's mortgage related investments. SIA
         requested that if management does not adopt such a distribution policy
         that a proposal to adopt such a policy be included in the proxy
         statement for consideration at the next annual meeting by the Issuer's
         shareholders (the letter was attached as an exhibit to Schedule 13D
         filed on July 9, 2009).



ITEM 5   Interest in Securities of the Issuer

         a)  As of April 9, 2010, SIA and its affiliates own 1,881,897 shares
             which represents 44.48% of the outstanding Shares. None of the
             executive officers or directors of SIA owns any other shares.
