Yet, even though that would permanently eliminate the discount, the Trustees have always opposed it. We think their real reason for opposing open-ending PCF is that they don't want to bite the hand that feeds them. They know that open-ending would probably reduce Putnam's fees. When you consider that last year, each of PCF's so-called independent trustees received between $290,000 and $482,000 to oversee more than one hundred Putnam funds, it's not hard to see why they would be reluctant to endorse anything that might adversely impact Putnam's revenues. You can do something about this. We are seeking your support for a proposal requesting that PCF conduct a self-tender offer at or close to NAV. We are also proposing to elect seven Trustees who will not hesitate to act solely in your interest even if Putnam's fees are adversely impacted. In sum, we think it is time for shareholders to finally be able to realize the full value of their investment by electing true independent Trustees. IT IS CRITICAL THAT YOU IMMEDIATELY RETURN THE ENCLOSED GREEN PROXY CARD. IF YOUR SHARES ARE HELD IN STREET NAME, YOU MAY VOTE ONLINE AT WWW.PROXYVOTE.COM OR BY TELEPHONE AT 1-800-454-8683. IF YOU HAVE ALREADY RETURNED MANAGEMENT'S PROXY CARD (EVEN IF YOU VOTED AGAINST THE BOARD'S NOMINEES), YOU MUST STILL VOTE OUR GREEN PROXY CARD IN ORDER TO ELECT OUR NOMINEES AS TRUSTEES. IF YOU HAVE ANY QUESTIONS ABOUT HOW TO VOTE YOUR PROXY, PLEASE CALL INVESTORCOM AT 1-877-972-0090. Very truly yours, /S/Phillip Goldstein Phillip Goldstein Principal Bulldog Investors, LLC PROXY STATEMENT OF BULLDOG INVESTORS, LLC IN OPPOSITION TO THE SOLICITATION BY THE BOARD OF TRUSTEES OF PUTNAM HIGH INCOME SECURITIES FUND FOR THE 2017 ANNUAL MEETING OF SHAREHOLDERS Bulldog Investors, LLC ("Bulldog Investors") is sending this proxy statement and the enclosed GREEN proxy card to shareholders of Putnam High Income Securities Fund (the "Fund") of record as of February 10, 2017. We are soliciting a proxy to vote your shares at the 2017 Annual Meeting of Shareholders (the "Meeting"), which is scheduled for April 28, 2017. Please refer to the Fund's proxy soliciting material for additional information concerning the Meeting and the matters to be considered by shareholders. This proxy statement and the enclosed GREEN proxy card are first being sent to shareholders on or about April 4, 2017. INTRODUCTION The Board of Trustees has determined to present two matters to be voted upon at the Meeting: a proposal to fix the number of trustees at twelve, and the election of twelve trustees. In addition, at the Meeting, Full Value Partners, L.P., a shareholder affiliated with us intends to present a non-binding proposal requesting that the Board of Trustees authorize a self-tender offer for all outstanding common shares of the Fund at or close to net asset value (NAV), and a proposal to fix the number of trustees at seven. We are soliciting a proxy to vote your shares AGAINST the proposal to fix the number of trustees at twelve, FOR the election of the seven nominees named below, and FOR the two shareholder proposals. REASONS FOR THE SOLICITATION We believe a seven-trustee board is sufficient to oversee the Fund. We also believe a self-tender offer at or close to NAV should be conducted in order to afford shareholders an opportunity to realize a price equal or close to NAV and that our nominees, if elected, will implement such a proposal, if it is adopted by shareholders. HOW PROXIES WILL BE VOTED If you complete and return a GREEN proxy card to us, and unless you direct otherwise, your shares will be voted AGAINST the proposal to fix the number of trustees at twelve, FOR the election of the seven nominees named below as trustees, and FOR the two shareholder proposals. In addition, you will be granting the proxy holders discretionary authority to vote on any other matters that may come before the Meeting. VOTING REQUIREMENTS A quorum for the transaction of business will exist if holders of thirty percent of the shares entitled to vote are represented at the Meeting. As of February 10, 2017, there were 12,977,000.942 shares outstanding. Each share is entitled to one vote. The election of a trustee requires the affirmative vote of a plurality of the votes cast, i.e., the nominees receiving the most votes will be elected. A majority of the votes cast is required to approve all other proposals. Since there are competing proposals to fix the number of trustees, we presume that the number of trustees (either seven or twelve) will be determined by which of the competing proposals receives the most votes. An abstention or a broker non-vote will have no effect on the election of trustees or whether a proposal is approved. REVOCATION OF PROXIES You may revoke your proxy prior to its exercise by: (i) delivering a written revocation to us; (ii) executing and delivering a later dated proxy to the inspector of election; or (iii) voting in person at the Meeting. Attendance at the Meeting will not by itself revoke a proxy. There is no limit on the number of times you may revoke your proxy and only your most recent proxy will be counted. PROPOSAL 1a. FIXING THE NUMBER OF TRUSTEES AT TWELVE The Board intends to propose that shareholders fix the number of trustees at 12. However, it does not provide a reason for its recommendation and we believe it is unnecessary to have such a large number of trustees. Therefore, unless instructions to the contrary are given, your proxy will be voted against this proposal. PROPOSAL 1b: ELECTION OF TRUSTEES Our affiliate intends to nominate the following seven persons for election as trustees, none of whom personally owns any shares of the Fund except for 10,772 shares beneficially owned jointly by Mr. Goldstein and his wife. Each nominee has consented to be nominated and, if elected, to serve as a trustee. The primary reason for selecting our nominees is that we know them to be advocates for shareholders and they are not beholden to Putnam for their positions. Including such shares, Messrs. Goldstein and Dakos may be deemed collectively to beneficially own 1,497,930 shares of the Fund as a result of their roles with Bulldog Investors, whose clients are the ultimate beneficial owners of such shares. In particular, Messrs. Goldstein and Dakos are members of Bulldog Investors, which is the general partner of, or the investment advisor for, certain investment funds, and are limited partners in one or more of such funds. Messrs. Goldstein and Dakos disclaim beneficial interest in all such shares except to the extent of any pecuniary interest in such funds. There are no arrangements or understandings between any of our nominees and Bulldog Investors or any of its affiliates in connection with the nomination. While none of our nominees are currently trustees of any funds in the "Putnam complex" of funds, on April 28, 1017, we intend to also nominate Messrs. Goldstein and Dakos for election as trustees by the holders of the preferred shares of two other closed-end funds in the "Putnam complex." Therefore, after April 28, 2017, Messrs. Goldstein and Dakos may be trustees of up to three funds in the "Putnam complex" of funds.

Unless instructions to the contrary are given, your proxy will be voted in favor of the aforementioned nominees for election as trustees and will withhold on the election of any other nominees. PROPOSAL 2. THE SHAREHOLDERS OF PUTNAM HIGH INCOME SECURITIES FUND (THE "FUND") REQUEST THAT THE BOARD OF TRUSTEES AUTHORIZE A SELF-TENDER OFFER FOR ALL OUTSTANDING COMMON SHARES OF THE FUND AT OR CLOSE TO NET ASSET VALUE (NAV). IF MORE THAN 50% OF THE FUND'S OUTSTANDING COMMON SHARES ARE SUBMITTED FOR TENDER, THE BOARD IS REQUESTED TO CANCEL THE TENDER OFFER AND TAKE THOSE STEPS THAT THE BOARD IS REQUIRED TO TAKE TO CAUSE THE FUND TO BE LIQUIDATED OR CONVERTED TO (OR MERGED WITH) AN EXCHANGE TRADED FUND (ETF) OR AN OPEN-END MUTUAL FUND.(This proposal is not binding.) A self-tender offer at or close to NAV will afford shareholders an opportunity to realize a price equal or close to NAV rather than selling at a discount to NAV. And, if a majority of the Fund's outstanding shares are tendered, that would demonstrate that there is insufficient shareholder support for continuing the Fund in its closed-end format. In that case, we think the tender offer should be cancelled and the Fund should be liquidated or converted into (or merged with) an ETF or an open-end mutual fund. This proposal is not binding. Moreover, certain transaction costs may be incurred in conducting a tender offer or the restructuring of the Fund. Lastly, we do not know if shareholder approval of any such restructuring is required under state law. PROPOSAL 3: THE NUMBER OF TRUSTEES SHALL BE FIXED AT SEVEN. We believe a seven-trustee board is sufficient to oversee the Fund. Unless instructions to the contrary are given, your proxy will be voted in favor of this proposal. THE SOLICITATION We intend to solicit proxies by mail, and may utilize other means, e.g., telephone or the internet. Our proxy materials are available at: www.bulldoginvestorsproxymaterials.com. Persons affiliated with or employed by us may assist us in the solicitation of proxies. Banks, brokerage houses and other securities intermediaries will be requested to forward this proxy statement and the enclosed GREEN proxy card to the beneficial owners for whom they hold shares of record. We will reimburse these organizations for their reasonable out-of-pocket expenses. Initially, we and our clients will bear all of the expenses related to this proxy solicitation. Because we believe that all shareholders will benefit from this solicitation, we intend to seek, subject to any applicable regulatory requirements, reimbursement of our expenses from the Fund. Shareholders will not be asked to vote on the reimbursement of these expenses, which we estimate will total $75,000. PARTICIPANTS As of April 4, 2017, Bulldog Investors, 250 Pehle Avenue, Suite 708, Saddle Brook, NJ 07663, the soliciting stockholder, beneficially owns 1,487,158 shares of the Fund which were purchased between November 20, 2015 and February 8, 2017. Separately Mr. Goldstein and his wife jointly own 10,772 shares in street name which were purchased from August 2015 to October 2015. No "participant" has any arrangement or understanding with any person with respect to any securities of the Fund or with respect to future employment by the Fund or any of its affiliates or to any future transactions to which the Fund or any of its affiliates will or may be a party. A "participant," as defined by the SEC, includes Bulldog Investors, Messrs. Goldstein, Dakos and Das, and each client advised by Bulldog Investors. The SEC's definition of a "participant" may be misleading because it suggests that a "participant" has a greater role in a solicitation than may be the case.
