Eaton Vance Senior Income Trust (EVF) -

Based on a review of reports filed by the Fund's trustees
and executive officers, the investment adviser, officers
and directors of the investment adviser, affiliated
persons of the investment adviser and beneficial
holders of 10% or more of the Fund's outstanding
shares, and written representations by the Reporting
Persons that no year-end reports were required for
such persons, the Fund believes all filings required by
Section 16(a) of the Securities Exchange Act of 1934 for
the fiscal year ended June 30, 2020 were timely, except
that Payson Swaffield filed a Form 5 late. Mr. Swaffield
has since corrected his omission by making the
necessary filing.
