         Common Stock

         Federated Enhanced Treasury Income Fund
         1001 Liberty Avenue
         Pittsburgh, PA 15222

ITEM 2   Identity and Background

         a) and c)

            This statement is filed by:
            Sit Investment Associates, Inc., a Minnesota corporation (SIA),and
            Sit Fixed Income Advisors II, LLC, a Delaware limited liability
            company (SFI). Both SIA and SFI are parties to a Joint Filing
            Agreement which was attached as an exhibit to the initial Schedule
            13D filed on March 18, 2015.

            SIA is a registered investment adviser.
            SFI is a registered investment adviser and subsidiary of SIA.

            SIA or SFI serves as investment adviser on behalf of its clients
            pursuant to investment management agreements with each of its
            clients which give SIA or SFI full discretionary authority to direct
            the investments of its client in accordance with the investment
            objectives and restrictions of the client. The investment management
            agreements also provide that SIA or SFI has assumed the
            responsibility to vote on behalf of its clients all shares held by
            its clients in accounts managed by SIA or SFI.

            Roger J. Sit is chairman and CEO of SIA and SFI.
            Michael C. Brilley is senior vice President of SIA and director,

            Mr. Ralph L. Strangis is a director of SIA and SFI. Mr. Strangis is
            a partner with the law firm Kaplan Strangis & Kaplan, P.A.

            By virtue of these positions, each of SIA, SFI, Mr. Sit, Mr.
            Brilley, Mr. Adler, and Mr. Strangis, may be deemed to beneficially
            own the Shares held in SIA and SFI client accounts. None of the
            named individuals own Shares directly. Additionally, neither Mr.
            Adler nor Mr. Strangis are involved in investment or voting
            decisions. SIA, SFI, Mr. Sit, Mr. Brilley, Mr. Adler, and Mr.
            Strangis together are the "Sit Entities".

         b) The business address of each of the Sit Entities is 3300 IDS
            Center, 80 South Eighth Street, Minneapolis, MN 55402

         d) During the last five years, neither Roger J. Sit, Michael C.
            Brilley, Frederick R. Adler, nor Ralph L. Strangis, have been
            convicted in a criminal proceeding (excluding traffic violations or
            similar misdemeanors).

         e) During the last five years, none of the Sit Entities have been a
            party to a civil proceeding of a judicial or administrative body of
            competent jurisdiction and as a result of such proceeding was or is
            subject to a judgment, decree, or final order enjoining future
            violations of, or prohibiting or mandating activities subject to,
            federal or state securities laws or finding any violation with
            respect to such laws.

         f) Roger J. Sit, Michael C. Brilley, Frederick R. Adler, and Ralph L.
            Strangis are United States citizens.

ITEM 3   Source and Amount of Funds or Other Consideration

         The Sit Entities acquired the Issuer's Shares in open market
         transactions with client funds held in custody accounts managed by SIA
         and SFI.

ITEM 4   Purpose of Transaction

         The Sit Entities have acquired the Issuer's Shares for investment
         purposes, and such purchases have been made in the ordinary course of
         business. The Issuer's Shares have been acquired on behalf of SIA's and
         SFI's clients.

         In pursuing such investment purposes, the Sit Entities purchased the
         Shares based on the Sit Entities' belief that the Shares represented an
         attractive investment opportunity, and the Sit Entities may further
         purchase, hold, vote, trade, sell or otherwise deal in the Shares at
         the time, and in such manner, as they deem advisable to benefit from,
         among many things, changes in market prices of such Shares, the market
         prices of such Shares relative to the value of the Issuer's assets,
         changes in the Issuer's investment strategy, and composition of the
         Issuer's portfolio.

         None of Sit Entities have any present plan or proposal which would
         relate to or result in any of the matters set forth in subparagraphs
         (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such
         as would occur upon or in connection with completion of, or following,
         any of the actions discussed herein.

         The Sit Entities intend to review their investment in the Issuer's
         Shares on a continuing basis and may from time to time engage in
         discussion with management, the Board of Directors and shareholders
         concerning, among other things, the Issuer's performance, the market
         prices of the Issuer's Shares relative to the value of the Issuer's
         assets, the Issuer's investment strategy and the Issuer's portfolio
         holdings.

ITEM 5   Interest in Securities of the Issuer

         a) and b)

            The aggregate percentage of Shares reported owned by Sit Entities
            herein is based upon 8,575,673 Shares outstanding as of May 31,
            2015, which is the total number of Shares outstanding as reported in
            the Issuer's Form N-CSRS dated May 31, 2015.

            As of the date hereof, the Sit Entities may be deemed to be the
            beneficial owner of 3,191,459 Shares held in client accounts which
            represent 37.22% of the Issuer's outstanding Shares. Each of the Sit
            Entities may be deemed to have shared power to vote and dispose of
            such Shares. However, none of SIA's or SFI's client accounts own
            more than 5% of the Shares outstanding, and none of SIA's or SFI's
            directors or executive officers own Shares directly.

         c) Transactions in Shares by the Sit Entities since the last 13D filing
            on July 30, 2015 is set forth in Exhibit A.


         d) The clients of SIA and SFI have the right to participate in the
            receipt of dividends from, or proceeds from the sales of, the Shares
            held for their respective accounts.

         e) Not applicable

ITEM 6   Contracts, Arrangements, Understandings, or Relationships with Respect
         to Securities of the Issuer

         Not applicable.

ITEM 7   Materials to be Filed as Exhibits

         the last 13D filing on July 30, 2015.

         certify that the information set forth in this statement is true,
         complete, and correct.
