Each shareholder may cast one vote for each full share, and a partial vote for each partial share, of the Fund that they owned of record on July ~~11, 2016~~3, 2017 (“Record Date”). Exhibit A shows the number of shares of the Fund that were outstanding on the Record Date, and Exhibit B lists the shareholders who owned 5% or more of the outstanding shares of any class of the Fund on that date. It is expected that this Proxy Statement and the accompanying Proxy Card will be first mailed to shareholders on or about July ~~29, 2016.~~

26, 2017.

This proxy solicitation is being made primarily by mail, but may also be made by officers or employees of the Fund or New York Life Investments or its affiliates, through telephone, facsimile, or other communications. The Fund ~~may~~has also ~~employ a professional proxy solicitation firm. If~~engaged a professional proxy solicitation firm ~~is used,~~to assist in the distribution and solicitation of proxies. The cost of the services of the professional proxy solicitation will be borne by the Fund. Please see the section titled “Other Information: Proxy Solicitation” for information regarding the professional proxy solicitation firm. The Fund may reimburse banks, brokers or dealers for their reasonable expenses in forwarding soliciting materials to beneficial owners of the Fund’s shares.

The Fund issues Common Shares and Preferred Shares. All shareholders of the Fund, both holders of Common Shares and holders of Preferred Shares, vote together to elect the Class III Trustee nominees other than the nominee for the Preferred Shares Trustee. The holders of Preferred Shares have the exclusive right to separately elect one Class III Trustee nominee as the Preferred Shares Trustee, in addition to the right to vote for the other Class III Trustee ~~nominees,~~nominee, together with the holders of the Common Shares. The following table sets forth the Class III Trustee ~~Nominees~~nominees by share class:

~~Share Class~~	~~Class I Trustee Nominee~~
Share Class		Class II Trustee Nominee
Common Shares and Preferred Shares	~~Susan B. Kerley~~

	~~Peter Meenan~~

	~~John A. Weisser~~
	Alan R. Latshaw
Preferred Shares	Jacques P. Perold*	Richard H. Nolan Jr.*

* The holders of Common Shares may not vote for this nominee.

The holders of Common Shares may not vote for this nominee.

The presence in person or by proxy of holders of thirty-three and one-third percent ~~(33⅓%~~(33 1/3%) of the Fund’s outstanding shares entitled to vote at the Meeting shall constitute a quorum. The presence in person or by proxy of holders of thirty-three and one-third percent ~~(33⅓%~~(33 1/3%) of the outstanding Preferred Shares entitled to vote at the Meeting shall

constitute a quorum of the Preferred Shares of the Fund for purposes of electing the one Trustee being elected solely by the holders of Preferred Shares. In the event that a quorum is not present or if sufficient votes are not received consistent with the Board’s recommendation regarding the proposal, management may propose an adjournment or adjournments of the Meeting. The Meeting, whether or not a quorum is present, may be adjourned for any lawful purpose by the Chairman of the Board, the Trustees (or their designees) or a majority of the votes properly cast upon the question of adjourning the Meeting, either in person or by proxy.

Abstentions and Broker ~~Non-Votes~~Non-Votes.. Because the only proposal scheduled to be considered at the Meeting is for the election of the Class III Trustees, the Fund does not expect to receive any abstentions or broker non-votes. In the unlikely event that ~~they do,~~it does, however, abstentions and broker non-votes will be included for purposes of determining whether a quorum is present for the Fund at the Meeting. They will be treated as votes present at the Meeting, but will not be treated as votes cast. In ~~effect,~~contrast, they would have the same effect as a vote “AGAINST” the proposal requiring a majority of votes present. Broker non-votes arise when shares are held in street name and the broker does not receive voting instructions from the beneficial owner. Broker non-votes can occur when a meeting has (i) a “routine” proposal, such as the election of trustees, where the applicable stock exchange permits brokers to vote their clients’ shares in their discretion, and (ii) a “non-routine” proposal, such as a change to the Fund’s fundamental investment policy, where the applicable exchange does not permit brokers to vote their clients’ shares in their discretion. The shares that are considered to be present as a result of the broker discretionary vote on the routine proposal but do not vote on the non-routine proposal are called “broker non-votes.” Because the proposal presented at the Meeting is considered to be a “routine” voting item (i.e., the election of the Class III Trustees), the Fund does not expect to receive any broker non-votes.

Copies of the Fund’s most recent annual report and semi-annual report, including financial statements, have been delivered to shareholders. Copies of these reports are available upon request, at no charge, by writing the Fund at MainStay Investments, 30 Hudson Street, Jersey City, New Jersey 07302 or by calling toll-free 855-456-9683.

THE PROPOSAL: TO ELECT CLASS III TRUSTEES OF THE FUND

The Fund’s Amended and Restated Agreement and Declaration of Trust provides that the Board shall be divided into three classes of Trustees, consisting, as nearly as may be possible, of one-third ~~(1/~~( 1/3) of the total number of Trustees constituting the entire Board. Each class serves for three years with one class being elected each year. Each year the term of office of one class will expire. ~~Susan B. Kerley, Peter Meenan~~Alan R. Latshaw and ~~John A. Weisser~~Richard H. Nolan Jr. were elected by shareholders of the Fund as a Class III Trustees at the ~~2013~~2014 annual meeting of shareholders of the Fund. The ~~Board appointed Jacques P. Perold as Class I Trustee as of January 1, 2016, to fill a vacancy the Board created by increasing the number of Trustees. The~~ terms of office of the Class III Trustees expire on the date of the Meeting.

In addition, Section 18 of the Investment Company Act of 1940, ~~Act,~~as amended (the “1940 Act”) requires that the holders of any preferred shares, voting separately as a single class without regard to series, have the right to elect at least two trustees at all times. In this regard, the holders of Preferred Shares have the exclusive right to separately elect Mr. ~~Perold~~Nolan as a Class III Trustee as ~~the~~a Preferred Shares Trustee, in addition to the right to vote for ~~Ms. Kerley and Messrs. Meenan, and Weisser,~~Mr. Latshaw, together with the holders of the Common Shares.

The Board, including the Trustees who are not “interested persons” of the Fund (as defined in Section 2(a)(19) of the ~~Investment Company Act of~~ 1940 Act ~~as amended (“1940 Act”))~~ upon the recommendation of the Fund’s Nominating and ~~Corporate~~ Governance Committee, which is comprised solely of Trustees who are not “interested persons” of the Fund (the “Independent Trustees”), have nominated ~~Ms. Kerley,~~ Mr. ~~Meenan, Mr. Perold~~Latshaw and Mr. ~~Weisser~~Nolan to serve as Class III Trustees for a three-year term expiring in ~~2019~~2020 or until their successors are duly elected and qualify. The nominees have indicated an intention to serve if elected and have consented to be named in this Proxy Statement. The above notwithstanding, the Board has a retirement policy which requires a Trustee to tender his or her resignation by the end of the calendar year during which he or she reaches the age of 75, subject to exceptions at the Board’s discretion. ~~Mr. Weisser will~~Neither of the nominees would reach the age of 75 during ~~the calendar year 2016. Accordingly,~~their term, if elected. Mr. Weisser is expected to serve until the end of calendar year 2016, at which time he intends to retire. Mr. Meenan also will reach the age of 75 during calendar year 2016, but the Board has approved an extension of his service until the end of calendar year 2017.

Pursuant to the Amended and Restated Agreement and Declaration of Trust, the Board may, but would not be required to, appoint a successor to continue Mr. Weisser’s term upon his retirement. In light of Mr. Weisser’s anticipated retirement during the term for which he is nominated and the requirements of Section 18 of the 1940 Act described above. Mr. Perold has been nominated for election to the position of Preferred Shares Trustee that is currently held by Mr. Weisser, and Mr. Weisser has been nominated for election to the Trustee position currently held by Mr. Perold.

It is the intention of the persons named on the enclosed Proxy Card to vote for the Class III Trustee nominees for a three-year term. The Board knows of no reason why a nominee would be unable to serve, but in the event of any such unavailability, the proxies received will be voted for such substituted nominees as the Board may recommend. Each of the current Trustees is an Independent Trustee, with the exception of ~~Christopher O. Blunt.~~Yie-Hsin Hung. The names of the Fund’s nominees for election as Class III Trustees and each other Trustee of the Fund, their dates of birth, position(s) held with the Fund, principal occupations during the past

five years and other directorships held by the nominee or Trustee are provided in the tables below. Information is provided as of June 30, ~~2016.~~2017. Unless otherwise noted, the address of each Trustee is c/o New York Life Investments, 51 Madison Avenue, New York, New York 10010.

In addition to its oversight of the Fund, the Board oversees ~~the~~ MainStay ~~Group of~~Funds Trust, The MainStay Funds, MainStay VP Funds Trust, ~~Private Advisors Alternative Strategies Master Fund, Private Advisors Alternative Strategies Fund,~~ the Manager and MacKay Shields LLC (“MacKay Shields” or “Subadvisor”), and elects the officers of the Fund who are responsible for the day-to-day operations of the Fund. Information pertaining to the Trustees and officers is set forth below. Under the Retirement Policy, unless an exception is made, a Trustee must tender his or her resignation by the end of the calendar year during which he or she reaches the age of 75. Officers serve a term of one year and are elected annually by the Board of Trustees. The business address of each Trustee below is c/o 51 Madison Avenue, New York, New York 10010.

Trustee Qualifications

In evaluating and selecting candidates for the Board, the Board intends to seek individuals who will serve the best interests of the Fund’s shareholders and whose attributes will, among other factors, also complement the experience, skills and diversity of the other Trustees and add to the overall effectiveness of the Board. In the evaluation of such candidates, the Board believes that diversity with respect to factors such as background, education, experience, skills, differences of viewpoint, race, gender, national origin, and other factors that contribute to the Board’s having an appropriate range of expertise, talents, experiences and viewpoints is an important consideration in the Board’s composition.

Board Structure and Leadership

The Board oversees the business and affairs of the Fund, including oversight of key service providers to the Fund, including New York Life Investments and MacKay Shields. The Board holds regularly scheduled in-person meetings and telephonic meetings on a quarterly basis and

other special in-person and telephonic meetings on an as needed basis. There are eight Trustees, seven of whom are considered Independent Trustees.

The Board has elected an Independent Trustee to serve as its Chairman. The Chairman is responsible for setting the agendas of all regular and special Board meetings, assists in identifying the information to be presented to the Board with respect to matters to be acted upon by the Board, and presides over all Board meetings. In between meetings, the Chairman is responsible for communicating with other Trustees, Fund officers, and personnel of New York Life Investments and other service providers as necessary to enable the Board to carry out its primary responsibility of overseeing the Fund and its operations.

As discussed further below, the Board has established various Committees through which the Trustees focus on matters relating to particular aspects of the Fund’s operations, such as valuation of portfolio holdings, investments, Fund fees, risk oversight and compliance and expenses and financial reporting.

The Trustees periodically review the effectiveness of the Committee structure and each Committee’s responsibilities and membership. The Trustees believe that the Board’s leadership and committee structure is appropriate in light of the nature and size of the Fund because, among other things, it fosters strong communication between the Board, its individual members, New York Life Investments and other service providers, allocates responsibilities among the Committees and permits Committee members to focus on particular areas involving the Fund. In addition, the Committees support and promote the Independent Trustees in their oversight of all aspects of the Fund’s operations and their independent review of proposals made by New York Life Investments.

Risk Oversight

While responsibility for day-to-day risk management relating to the Fund and its operations resides with the Manager, the Subadvisor or other service providers (subject to the supervision of the Manager), the Board actively performs a risk oversight function, both directly and through its Committees, as described below.

The Board and its Committees exercise this function through regular and ad hoc Board and Committee meetings during which the Board and its Committees meet with representatives of the Manager, the Subadvisor, and other key service providers. In addition, the Board has established a Risk and Compliance Oversight Committee that has the responsibility of coordinating the Board’s oversight of the implementation of the risk

management and compliance programs of, and related to, the Fund. The Audit Committee also meets regularly with the Fund’s independent registered public accounting firm and Principal Financial and Accounting Officer to discuss internal controls and financial reporting matters, among other things. The Board and Committees regularly require senior management of the Manager and senior officers of the Fund to report to the Board and the Committees on a variety of risk areas relating to the Fund, including, but not limited to, investment/portfolio risks (e.g., performance, compliance, counterparty, credit, liquidity and valuation risks) and operational/enterprise risks (e.g., financial, reputational, compliance, litigation, personnel and business continuity risks), as well as more general business risks. The Board reviews, on an ongoing basis, the Fund’s performance, operations and investment practices. The Board also conducts reviews of the Manager in its role in managing the Fund’s operations. In addition, the Board has engaged counsel to the Independent Trustees and consults with such counsel both during and between meetings of the Board and the Committees.

The Board and the Risk and Compliance Oversight Committee also meet regularly with the Fund’s Chief Compliance Officer ~~("CCO"~~(“CCO”), who reports directly to the Board. The CCO has responsibility for testing the compliance procedures of the Fund and its service providers. The CCO regularly discusses issues related to compliance and provides a quarterly report to the Board regarding the Fund’s compliance program. In order to maintain a robust risk management and compliance program for the Fund, the Board and the Risk and Compliance Oversight Committee also regularly review and ~~approve,~~consider for approval, as necessary, the Fund’s compliance policies and procedures and updates to these procedures, as well as review and ~~approve~~consider for approval the compliance policies and procedures of certain of the Fund’s service providers to the extent that those policies and procedures relate to the operations of the Fund. In addition to the meetings with various parties to oversee the risk management of the Fund, the Board and its Committees also receive regular written reports from these and other parties which assist the Board and the Committees in exercising their risk oversight function.

The Board also benefits from other risk management resources and functions within the ~~Manager's~~Manager’s organization, such as the ~~Manager's~~Manager’s risk management personnel and the internal auditor of the ~~Manager's~~Manager’s parent company. For example, the Board and the Risk and Compliance Oversight Committee meet periodically with the ~~Manager's~~Manager’s risk management personnel, including the ~~Manager's~~Manager’s Chief Risk Officer ~~("CRO"~~(“CRO”). The CRO is responsible for overseeing the measurement and monitoring of operational risks across the ~~Manager's~~Manager’s enterprise. In

addition, the Board benefits from the work of the Manager’s Risk Management Committee, which is comprised of senior personnel of the Manager and seeks to identify and address material risks within the ~~Manager's~~Manager’s businesses across its multi-boutique structure. The Board recognizes that it is not possible to identify all of the risks that may affect the Fund or to develop processes and controls to mitigate or eliminate all risks and their possible effects, and that it may be necessary to bear certain risks (such as investment risks) to achieve the Fund’s investment objectives. The Board may, at any time and in its discretion, change the manner in which it conducts risk oversight.

Board Committees

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” THE ELECTION OF EACH OF THE CLASS III TRUSTEE NOMINEES

Independent Registered Public Accounting Firm

The firm of PricewaterhouseCoopers LLC (“PwC”) has been selected as the independent registered public accounting firm (“independent auditors”) for the Fund. In accordance with Public Company Accounting Oversight Board Rule 3526 (“PCAOB Rule 3526”), PwC has informed the Fund’s Audit Committee that it may not qualify as independent under Rule 2-01 of Regulation S-X (the “Loan Provision”), as interpreted by the Staff of the U.S. Securities and Exchange Commission (“SEC”), in light of a lending relationship PwC maintains with a shareholder of the Fund. PwC has indicated that this relationship does not influence the audits of the Fund or PwC’s objectivity and impartiality on issues encompassed within its engagement, and that it believes that a reasonable investor possessing all the facts regarding its borrowing and audit relationships would conclude that PwC was able to exhibit the requisite objectivity and impartiality to report on the Fund’s financial statements. Legal counsel to the Fund has advised the Fund that it may rely on ~~recent~~ “no-action” relief granted by the Staff of SEC to continue to fulfill its regulatory requirements under the federal securities laws by using the audit services performed by PwC. PwC acted as independent auditors of the Fund for its most recently completed fiscal year, and has been appointed as independent auditors for the Fund’s current fiscal year.

The Audit Committee must approve all audit and non-audit services provided by the Fund’s independent auditors relating to the operations or financial reporting of the Fund. The Audit Committee reviews any audit or non-audit services to determine whether they are appropriate and permissible under applicable law.

The Audit Committee has adopted pre-approval policies and procedures (“Procedures”) to govern the Committee’s pre-approval of (i) all audit services and permissible non-audit services to be provided to the Fund by the independent auditors, and (ii) all permissible non-audit services to be provided by such independent auditors to New York Life Investments and to any entity controlling, controlled by or under common control with New York Life Investments that provides ongoing services to the Fund (collectively, “Service Affiliates”) if the services directly relate to the Fund’s operations and financial reporting. In accordance with the Procedures, the Audit Committee is responsible for the engagement of the independent auditors to certify the Fund’s financial statements for each fiscal year. With respect to the pre-approval of non-audit services provided to the Fund and its Service Affiliates, the Procedures provide that the Audit Committee may annually pre-approve a list of the types of services that may be provided to the Fund or its Service Affiliates, or the Audit Committee may pre-approve such services on a project-by-project basis as they arise. Unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committee if it is to be provided by the independent accountant. The Procedures also permit the Audit Committee to delegate authority to one or more of its members to pre-approve any proposed non-audit services that have not been previously pre-approved by the Audit Committee, subject to the ratification by the full Audit Committee no later than its next scheduled meeting. To date, the Audit Committee has not delegated such authority.

The Audit Committee has reviewed and discussed with the management of the Fund and representatives from PwC the audited financial statements for the Fund’s last fiscal year. The Audit Committee has discussed with PwC its judgments as to the quality, not just the acceptability, of the Fund’s accounting principles and such other matters required to be discussed with the Audit Committee by Statement on Auditing Standards No. 114 (The Auditor’s Communication With Those Charged With Governance). The Audit Committee also received the written disclosures and the letter from PwC required by PCAOB Rule 3526, and discussed with a representative of PwC the independent auditor’s independence, including with respect to compliance with the Loan Provision discussed above. The Board also considered fees received by PwC from New York Life Investments and its affiliates during the last fiscal year in connection with its consideration of the auditors’ independence. Based on the foregoing discussions with management and the independent auditors, the Audit Committee recommended to the Board that the aforementioned audited financial statements be included in the Fund’s annual report to shareholders for the last fiscal year.

As noted above, the members of the Fund’s Audit Committee are: Alan R. Latshaw (Chairman), David H. Chow and ~~John A. Weisser, Jr.~~Susan B. Kerley. All members of the Audit Committee meet the standard of independence set forth in the listing standards of the NYSE, and are not considered to be “interested persons” under the 1940 Act. The Board has adopted a formal charter for the Audit Committee setting forth its responsibilities.

Representatives of PwC are not expected to attend the Meeting, but have been given the opportunity to make a statement if they so desire, and will be available should any matter arise requiring their response.

Audit Fees

For the fiscal year ended May 31, ~~2016,~~2017, the aggregate fees billed for professional services rendered by PwC for the audit of the Fund’s annual financial statements or services that are normally provided by PwC in connection with statutory and regulatory filings or engagements were ~~$74,500.~~$71,600.
