	Information required by Instruction C of Schedule 13D with respect to Reporting Person is set forth herein.

Item 3.

SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

Funds for the purchase of the Common Shares were derived from the subscription proceeds from investors in the funds and accounts managed by Saba Capital and the capital appreciation thereon and margin account borrowings made in the ordinary course of business. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the account, which may exist from time to time. Since other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Common Shares reported herein. A total of $61,768,411 was paid to acquire the Common Shares reported herein.

Item 4.

PURPOSE OF TRANSACTION

The Reporting Persons acquired the Common Shares to which this Schedule 13D relates in the ordinary course of business for investment purposes because they believe that the Common Shares are undervalued and represent an attractive investment opportunity.

The Reporting Persons may engage in discussions with management, the Board of Trustees (the Board), other shareholders of the Issuer and other relevant parties, including representatives of any of the foregoing, concerning the Reporting Persons' investment in the Common Shares and the Issuer, including, without limitation, matters concerning the Issuer's business, operations, board appointments, governance, performance, management, capitalization, trading of the Common Shares at a discount to the Issuers net asset value and strategic plans and matters relating to the open or closed end nature of the Issuer and timing of any potential liquidation of the Issuer. The Reporting Persons may exchange information with any persons pursuant to appropriate confidentiality or similar agreements or otherwise, work together with any persons pursuant to joint agreements or otherwise, propose changes in the Issuer's business, operations, board appointments, governance, management, capitalization, strategic plans or matters relating to the open or closed end nature of the Issuer or timing of any potential liquidation of the Issuer, or propose or engage in one or more other actions set forth herein.

On February 8, 2019, Saba Capital submitted to the Issuer a proposal (the Proposal) pursuant to Rule 14a-8 promulgated under the Act. The Proposal requests that the Board take all necessary steps in its power to declassify the Board so that all directors are elected on an annual basis starting at the next annual meeting of shareholders.

Such declassification shall be completed in a manner that does not affect the unexpired terms of the previously elected trustees. The foregoing description of the Proposal is qualified in its entirety by the full text of the Proposal, a copy of which is attached as Exhibit 2 hereto and incorporated by reference herein.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors, including, without limitation, the outcome of any discussions referenced above, the Issuer's financial position and strategic direction, actions taken by management or the Board, price levels of the Common Shares, other investment opportunities available to the Reporting Persons, conditions in the securities market and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate, including, without limitation, purchasing additional Common Shares or selling some or all of their Common Shares, engaging in short selling of or any hedging or similar transactions with respect to the Common Shares and/or otherwise changing their intention with respect to any and all matters referred to in Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or additional proposals with respect to their investment in the Common Shares.

The Reporting Persons have not entered into any agreement with any third party to act together for the purpose of acquiring, holding, voting or disposing of the Common Shares reported herein.

Chief Legal Officer and Secretary
Invesco Senior Income Trust

Re: Invesco Senior Income Trust (the Trust)

Dear Mr. Kupor:

     Saba Capital Management, L.P. (Saba), as investment advisor to and on behalf of Saba II AIV, LP (the Fund and together with Saba, the Saba Group), the owner of 14,857,607 shares of Trust, hereby submits the following proposal on behalf of the Fund pursuant to Rule 14a-8 promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act), for presentation to the Trusts shareholders at the Trusts next annual shareholders meeting to be held in 2019, or any postponement or adjournment or special meeting held in lieu thereof (the Meeting).

     Sabas proposal (the Proposal) pursuant to Rule 14a-8 under the Securities Exchange Act of 1934 (the Exchange Act) is as follows:

	PROPOSAL
	RESOLVED, that the shareholders of Invesco Senior Income Trust (the Trust)
	request that the Board of Trustees of the Trust (the Board) take all necessary
	steps in its power to declassify the Board so that trustees are elected on an annual
	basis starting at the next annual meeting of shareholders. Such declassification
	shall be completed in a manner that does not affect the unexpired terms of the
	previously elected trustees.

SUPPORTING STATEMENT

Corporate Governance

     We believe the annual election of all trustees encourages board accountability to its shareholders and when trustees are held accountable for their actions, they perform better. This view is shared by most shareholders and institutional investors, who believe it to be the standard for corporate governance best practices. The vast majority of companies in the S&P 500 and Russell 1000 indexes elect all board members annually.

     Currently, the Board is divided into three classes serving staggered three-year terms. It is our belief that the classification of the Board is strong proof that the Board is not acting in the best interests of shareholders. A classified board protects the incumbents, which in turn limits accountability to shareholders.

      We are committed to improving the corporate governance of the Trust for the benefit of all shareholders. Declassification of the Board is a positive step which will allow more productive shareholder engagement and will help the Trust achieve its optimal valuation.

     Saba Capital has submitted a shareholder proposal to declassify the Board of the Trust, in an attempt to allow the Board to operate freely and in the best interest of shareholders.

     For a greater voice in the Trusts corporate governance and to increase the accountability of the Board to shareholders, we urge you to vote FOR this proposal.

END OF PROPOSAL

     As is required by Rule 14a-8 under the Exchange Act, attached is letter from National Financial Services verifying that the Fund continuously and beneficially owned shares having a market value of $2,000 or more for at least one year prior to the date of the submission of the above Proposal. As of the date hereof, the Fund has continuously held the required number of shares for over a one-year period. The Fund intends to continue to hold the shares referenced through the date of the Meeting.

     Saba represents that, as investment advisor to the Fund, Saba holds beneficial interest in all shares held by the Fund, including full economic interest in such shares along with the power to invest, vote, or direct the vote of such shares and has full power and authority to submit the Proposal on the Fund's behalf.

     Please notify us as soon as possible if you would like any further information or if you believe this notice is deficient in any way or if additional information is required so that Saba may promptly provide it to you in order to cure any deficiency.

     Thank you for your time and consideration.

Sincerely,

Michael DAngelo
General Counsel
