To authorize a proxy to cast your votes, please date, execute and mail the enclosed proxy card, or authorize a proxy by using telephone or internet options as instructed in the proxy card. Except for Proposals (1) and (2), referred to above, the proxies confer discretionary authority on the persons named therein or their substitutes with respect to any business that may properly come before the meeting. Stockholders retain the right to revoke executed proxies at any time before they are voted by written notice to the Fund, by executing a later dated proxy, or by appearing and voting at the meeting. All shares represented at the meeting by proxies in the accompanying form will be voted, provided that such proxies are properly executed.

In cases where no specifications are made, the shares represented will be votedFORProposal (1) andFOR Proposal (2).

Who May Vote

Only stockholders of record at the close of business on February 5, 2016, may vote at the Annual Meeting. The total number of shares of Common Stock of the Fund outstanding and entitled to be voted on the record date was 97,802,161. Each share is entitled to one vote. The Fund has no other class of security outstanding.

Vote Requirement

For Proposal (1), referred to above, directors shall be elected by a plurality of the votes cast at the meeting. Proposal (2), referred to above, requires the affirmative vote of a majority of the votes cast at the meeting.

Quorum Requirement

A quorum is necessary to hold a valid meeting. If stockholders entitled to cast a majority of all the votes entitled to be cast at the Annual Meeting are present in person or by proxy, a quorum will exist. Proxies received by the Fund that are marked “withhold authority” or abstain, or that constitute a broker non-vote, are counted as present for purposes of establishing a quorum. A broker non-vote occurs when a broker returns a valid proxy but does not vote on a particular matter because the broker does not have the discretionary voting power for that matter and has not received instructions from the beneficial owner. Proxies marked “withhold authority”, abstentions and broker non-votes do not count as votes cast with respect to any proposal, and therefore, such proxies would have no effect on the outcome of Proposals (1) and (2), above.

Appraisal Rights

Under Maryland law, there are no appraisal or other dissenter rights with respect to any matter to be voted on at the Annual Meeting that is described herein.

Other Matters

The Fund will pay all costs of soliciting proxies in the accompanying form. See “Other Matters and Annual Report” below. Solicitation will be made by mail, and officers, regular employees, and agents of the Fund may also solicit proxies by telephone or personal interview. The Fund expects to request brokers and nominees who hold stock in their names to furnish this proxy material to their customers and to solicit proxies from them, and will reimburse such brokers and nominees for their out-of-pocket and reasonable clerical expenses in connection therewith.

Fund Complex

The Fund is part of a fund complex (the “Fund Complex”) which is composed of the Fund and Adams Natural Resources Fund, Inc., a closed-end investment company formerly known as Petroleum & Resources Corporation (“PEO”). Effective March 31, 2015, the Fund and PEO became part of a newly-branded Adams Funds platform.

(1) NOMINEES FOR ELECTION AS DIRECTORS

Unless contrary instructions are given by the stockholder signing a proxy, it is intended that each proxy in the accompanying form will be voted at the Annual Meeting for the election of the following

2

nominees to the Board of Directors to serve until the annual meeting of stockholders in 2017 and until their successors are duly elected and qualify, all of whom have consented to serve if elected:

If for any reason one or more of the nominees above-named shall become unable or unwilling to serve when the election occurs, proxies in the accompanying form will, in the absence of contrary instructions, be voted for the election of the other above-named nominees and may be voted for substitute nominees in the discretion of the persons named as proxies in the accompanying form. As an alternative to proxies being voted for substitute nominees, the size of the Board of Directors may be reduced so that there are no vacancies caused by a nominee above-named becoming unable or unwilling to serve.

(1) The valuation date used in calculating the dollar value of shares owned is December 31, 2015.

In 2009, the Board adopted new equity ownership requirements for the directors and senior staff. Under these equity ownership requirements, the Chief Executive Officer, portfolio managers, research analysts, and other executive officers must own, within 3 years of the requirement’s adoption or commencement of employment, as applicable, a certain value of equity in the Fund equal to a multiple of his or her 2009 annual salary or starting salary, as applicable. Non-employee directors with more than 5 years of service on the Board must own, by December 14, 2014, at least $100,000 of Common Stock of the Fund; non-employee directors with less than 5 years of service, and new directors, must own at least $100,000 of the Fund’s Common Stock within 10 years of joining the Board.

Board Leadership Structure

Seven of the Fund’s eight directors are not “interested persons,” as defined by the Investment Company Act of 1940, as amended (the “Act”), and are independent directors. Mr. Stoeckle is the only member of the Board who is an “interested person” under the Act and thus is not an independent director. The Board has elected Dr. Kathleen T. McGahran, an Independent Director, to serve as Chair of the Board.

Board’s Oversight of Risk Management for the Fund

The Board’s role in risk management of the Fund is that of oversight. The internal staff of portfolio managers, research analysts and administrative personnel is responsible for the day-to-day management of the Fund, including risk management (including management of investment performance and investment risk, valuation risk, issuer and counterparty credit risk, compliance risk and operational risk). As part of its oversight, the Board has delegated to the Audit Committee the primary role of overseeing the assessment and management of risks, including major financial risks, by the Fund’s management, and the steps that management has taken to monitor and control such risks. The Audit Committee reports to the Board on a periodic basis on its discussions of these items with management. In addition, the Board, acting at its regularly scheduled meetings, receives reports from senior management, including the Fund’s portfolio management team, the Chief Compliance Officer and the Chief Financial Officer. Between Board meetings, the Executive Committee, and/or Chair of the Board, and/or the Chairman of the Audit Committee, as appropriate, interacts with the CEO and other senior executives on any matter requiring action by or notice to the Board. The Board also receives periodic presentations from senior management regarding specific operational, compliance or investment areas such as business continuity, personal trading, valuation, investment research and securities lending, and receives reports from the Fund’s General Counsel regarding regulatory, compliance and governance matters. The Fund believes that its leadership structure enhances risk oversight. It should be noted that, in its oversight role, the Board is not a guarantor of the Fund’s investments or activities.

Process for Stockholders to Communicate with Board

The Board of Directors has implemented a process for stockholders of the Fund to send communications to the Board. Any stockholder desiring to communicate with the Board, or with specific individual directors, may do so by writing to the Secretary of the Fund, at Adams Diversified Equity Fund, Inc., 500 East Pratt Street, Suite 1300, Baltimore, MD 21202. The Secretary has been instructed by the Board to promptly forward all such communications to the addressees indicated thereon.

Policy on Board of Directors’ Attendance at Annual Meetings

The Fund’s policy with regard to attendance by the Board of Directors at Annual Meetings is that all directors are expected to attend, absent unusual and extenuating circumstances that prohibit attendance. All of the directors then serving attended the 2015 Annual Meeting.

Section 16(a) Beneficial Ownership Reporting Compliance

Each director and officer of the Fund who is subject to Section 16 of the Securities Exchange Act of 1934, as amended, and persons who own more than ten percent of a registered class of the Fund’s securities are required to report to the Securities and Exchange Commission (the “Commission”) by a specified date his or her beneficial ownership of or transactions in the Fund’s securities. Based upon a review of filings with the Commission, such forms received by the Fund, and written representations that no other reports are required, the Fund believes that each director, officer, and greater than ten percent beneficial owners filed all requisite reports with the Commission on a timely basis during 2015, except for Mr. Stoeckle, whose Form 4 reporting the payment of the tax liability incident to the vesting of restricted stock by withholding shares was filed one day late.

Board Meetings and Committees of the Board

Overall attendance at the eight meetings of the Board held in 2015 was 100%. Each incumbent director attended at least 75% of the total of all (i) meetings of the Board and (ii) meetings of committees of the Board on which he or she served in 2015.

Audit Committee

Mr. Escherich (Chair), Dr. Arzac, Ms. Bonanno, and Dr. Smith, each of whom is an independent director as such is defined by the rules of the New York Stock Exchange, and none of whom is an “interested person” as such is defined by the Act, constitute the membership of the Board’s standing Audit Committee, which met four times in 2015. The Board has determined Mr. Escherich to be an audit committee financial expert, as that term is defined in federal regulations.

The Board has adopted a written charter under which the Audit Committee operates. A copy of the Audit Committee Charter (“Charter”) is available on the Fund’s website:www.adamsfunds.com. Set forth below is the report of the Audit Committee:

Audit Committee Report

The purposes of the Audit Committee are set forth in the Audit Committee’s written Charter. As provided in the Charter, the role of the Audit Committee is to assist the Board of Directors in its oversight on matters relating to accounting, financial reporting, internal control, auditing, risk assessment and risk management, and regulatory compliance activities, and other matters the Board deems appropriate. The Audit Committee also selects the Fund’s independent registered public accounting firm in accordance with the provisions set out in the Charter. Management, however, is responsible for the preparation, presentation and integrity of the Fund’s financial statements, and for the procedures designed to assure compliance with accounting standards and applicable laws and regulations. The independent registered public accounting firm is responsible for planning and carrying out proper audits and reviews.

In fulfilling its responsibilities, the Audit Committee has reviewed and discussed the audited financial statements contained in the 2015 Annual Report of the Fund with the Fund’s management and with PricewaterhouseCoopers LLP (“PwC”), the independent registered public accounting firm. In addition, the Audit Committee has discussed with PwC the matters required to be discussed pursuant to Statement of Auditing Standards No. 61, as modified or supplemented. The Audit Committee has also received from PwC the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding PwC’s communications with the Audit Committee concerning independence, considered whether the provision of nonaudit services by PwC is compatible with maintaining PwC’s independence, and discussed with PwC its independence.

In reliance on the reviews and discussions with management and PwC referred to above, and subject to the limitations on the responsibilities and role of the Audit Committee set forth in the Charter and discussed above, the Audit Committee recommended to the Board of Directors, and the Board has approved, that the audited financial statements be included in the Fund’s 2015 Annual Report for filing with the Securities and Exchange Commission.

Respectfully submitted on February 11, 2016, by the members of the Audit Committee of the Board of Directors:

Frederic A. Escherich, Chair

Enrique R. Arzac

Phyllis O. Bonanno

Craig R. Smith

Compensation Committee

Mr. Dale (Chair), Ms. Bonanno, Mr. Escherich, and Dr. Gale constituted the membership of the Board’s standing Compensation Committee in 2015, which met two times. The Compensation Committee reviews and recommends changes in the compensation of directors, officers, and employees, including salaries and the cash and equity incentive compensation plans in which the executive officers, officers, and employees of the Fund are eligible to participate.

Executive Committee

Dr. McGahran (Chair), Dr. Arzac, Mr. Dale, Dr. Gale, Dr. Smith and Mr. Stoeckle constituted the membership of the Board’s standing Executive Committee in 2015, which met two times. The Executive Committee has the authority of the Board of Directors between meetings of the Board except as limited by law, the Fund’s Bylaws, or Board resolution.

Nominating and Governance Committee

Dr. Smith (Chair), Dr. Arzac, Mr. Dale, and Dr. Gale constituted the membership of the Board’s standing Nominating and Governance Committee in 2015, which met two times. The Board has adopted a written charter under which the Nominating and Governance Committee operates, a copy of which is available to stockholders at the Fund’s website:www.adamsfunds.com.

Each of the members of the Nominating and Governance Committee is an independent director as such is defined by the rules of the New York Stock Exchange and none is an “interested person” as such is defined by the Act.

The Nominating and Governance Committee recommends to the full Board nominees for director and leads the search for qualified director candidates.

The Nominating and Governance Committee will consider unsolicited recommendations for director candidates from stockholders of the Fund. Stockholders may recommend candidates for consideration by the Nominating and Governance Committee by writing to the Secretary of the Fund at the office of the Fund, 500 East Pratt Street, Suite 1300, Baltimore, MD 21202, giving the candidate’s name, biographical data and qualifications and stating whether the candidate would be an “interested person” of the Fund. A written statement from the candidate, consenting to be named as a candidate, and if nominated and elected, to serve as a director, should accompany any such recommendation.

The process that the Nominating and Governance Committee uses for identifying and evaluating nominees for director is as follows: When there is a vacancy on the Board, either through the retirement of a director or the Board’s determination that the size of the Board should be increased, nominations to fill that vacancy are made by independent directors on the Board. The members of the Nominating and Governance Committee meet with the prospective director nominee. If a majority of the Nominating and Governance Committee members are satisfied that the prospective director

11

nominee is qualified and will make a positive addition to the Board, as many of the other independent directors meet with him or her as is possible. The Nominating and Governance Committee then nominates the candidate at a meeting of the Board and a vote is taken by the full Board on whether to elect the nominee to the Board and to include the nominee in the Fund’s proxy for election at the next annual meeting of stockholders. The Fund anticipates that a similar process will be used for any qualified director candidate properly recommended by a stockholder.

The Board does not have a formal policy regarding the consideration of diversity in identifying Board candidates. When considering a new candidate for the Board, the Nominating and Governance Committee and the full Board may consider the diversity of skills, experience and/or perspective a prospective nominee will bring to the Board as part of their evaluation of the contribution that such prospective director nominee will make to the Board. Such factors will be considered in the context of the Board’s existing membership at the time such potential candidate is considered.

Retirement Benefits Committee

Dr. Gale (Chair), and Messrs. Dale and Escherich constituted the membership of the standing Retirement Benefits Committee of the Fund, which administered the Fund’s Employee Retirement Plan and Supplemental Retirement Plan. This Committee met two times during 2015. This Committee was disbanded in July 2015 following the termination of the Employees’ Retirement Plan and Supplemental Retirement Plan and the distribution of the plan assets to the participants. Previously, this Committee also administered the Fund’s Employee Thrift Plan and Executive Nonqualified Supplemental Thrift Plan. Those plans are now administered by a committee comprised of employees of the Fund.

Board of Directors Compensation

During 2015, each director who is not an interested person, except for Dr. McGahran, received an annual retainer fee of $60,000. Dr. McGahran, the Board Chair, received an annual retainer fee of $75,000. The Chairperson of each committee received an additional annual retainer fee of $2,500 for that committee. The total amount of fees paid to the independent directors in 2015 was $444,375.

Transactions with Adams Natural Resources Fund, Inc.

The Fund shares certain expenses for research, accounting services, other office services (including proportionate salaries and other employee benefits), rent and related expenses, and miscellaneous expenses, such as office supplies, postage, subscriptions and travel, with PEO, of which all of the above-named nominees are also directors. These expenses were paid by the Fund and, on the date the payment was made, PEO simultaneously paid to the Fund its allocated share of such expenses, based on either the proportion of the size of the investment portfolios of the two companies, or, where possible, on an actual usage basis. In 2015, PEO’s share of such expenses was $1,262,189.

Audit Fees

The aggregate fees for professional services rendered by the Fund’s independent registered public accounting firm, PricewaterhouseCoopers LLP, for the audit of the Fund’s annual financial statements and review of the Fund’s semi-annual financial statements for 2015 and 2014 were $78,138 and $75,403, respectively.

12

Audit-Related Fees

There were no audit-related fees in 2015 and 2014.

Tax Fees

The aggregate fees for professional services rendered to the Fund by PricewaterhouseCoopers LLP for the review of the Fund’s excise tax calculations and preparations of federal, state and excise tax returns for 2015 and 2014 were $9,462 and $9,646, respectively.

All Other Fees

The aggregate fees for services rendered to the Fund by PricewaterhouseCoopers LLP, other than for the services referenced above, for 2015 and 2014 were $4,315 and $4,190, respectively, which related to the review of the Fund’s procedures for calculating the amounts granted or vested for the Fund’s employees in accordance with the Fund’s 2005 Equity Incentive Compensation Plan, review of the Fund’s calculations related to that plan, and preparation of a related report to the Fund’s Compensation Committee.

The Board’s Audit Committee has considered the provision by PricewaterhouseCoopers LLP of the services covered in thisAll Other Fees section and found that they are compatible with maintaining PricewaterhouseCoopers LLP’s independence.

Audit Committee Pre-Approval Policy

The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by the independent accountants. In assessing requests for services by the independent accountants, the Audit Committee considers whether such services are consistent with the auditor’s independence; whether the independent accountants are likely to provide the most effective and efficient service based upon their familiarity with the Fund; and whether the service could enhance the Fund’s ability to manage or control risk or improve financial statement audit and review quality. The Audit Committee may delegate pre-approval authority to its Chair. Any pre-approvals by the Chair under this delegation are to be reported to the Audit Committee at its next scheduled meeting. All services performed for 2015 were pre-approved by the Audit Committee.

2005 Equity Incentive Compensation Plan

In 2005, the Board of Directors adopted an equity incentive compensation plan for the Fund, called the 2005 Equity Incentive Compensation Plan (the “2005 Plan”), to replace the Stock Option Plan adopted in 1985 and described below. The 2005 Plan was reapproved by the stockholders at the 2010 Annual Meeting. The 2005 Plan expired by its terms on April 27, 2015, and grants can no longer be made under it though awards are still outstanding.

Administration

The 2005 Plan is administered by the Compensation Committee of the Board of Directors. The Compensation Committee has general responsibility to ensure that the 2005 Plan is operated in a manner that serves the best interests of the Fund’s stockholders.

15

Available Shares

The Fund had reserved and made available 3,413,131 shares for use as awards (4% of the Fund’s Common Stock outstanding on the effective date of the 2005 Plan). With the expiration of the 2005 Plan, grants can no longer be made under it though awards are still outstanding.

Awards

The following types of awards are currently outstanding under the 2005 Plan:

• restricted stock;

• restricted stock units;

• deferred stock units; and

• performance awards.

In addition, dividend equivalents were awarded in connection with awards under the 2005 Plan.

The awards are described more fully below. Grants to non-employee directors were limited to those described below under “Non-Employee Director Awards”.

Restricted Stock. The 2005 Plan permitted shares of the Fund’s Common Stock to be granted to Participants as restricted stock. Restricted stock is stock that is subject to restrictions on transferability, risk of forfeiture and/or other restrictions. A Participant who receives restricted stock will have all the rights of a stockholder, including the right to vote the restricted stock and the right to receive dividends, unless the Participant is limited by the terms of the 2005 Plan or any award agreement relating to the restricted stock. During the period of restriction, the Participant may not sell, transfer, pledge, hypothecate, margin, or otherwise encumber the restricted stock.

Restricted Stock Units. The 2005 Plan permitted restricted stock units to be granted to Participants. Restricted stock units represent rights to receive stock and are subject to certain restrictions and a risk of forfeiture.

Deferred Stock Units. The 2005 Plan authorized deferred stock units to be granted to Participants. A deferred stock unit is the right to receive stock, cash, or a combination of stock and cash at the end of a time period specified by the Compensation Committee. Deferred stock units may or may not be subject to restrictions (which may include a risk of forfeiture), which restrictions will lapse at the expiration of the specified deferral period or at earlier times, as determined by the Compensation Committee.

Performance Awards. The 2005 Plan permitted the Compensation Committee to make any award under the 2005 Plan subject to performance conditions. The Fund could pay performance awards in cash or shares of the Fund’s Common Stock. The grant, exercise and/or settlement of performance awards would be contingent upon the achievement of pre-established performance goals, unless the Compensation Committee determines that a performance award is not intended to qualify as “performance-based compensation” for purposes of Code Section 162(m). (Code Section 162(m) provides that compensation in excess of one million dollars to certain officers of a public company is not deductible for income tax purposes unless it qualifies as “performance-based compensation”.)

Non-Employee Director Awards

Immediately following each annual meeting of stockholders, each non-employee director who was elected a director at the meeting, or who was previously elected and continued as a director after that annual meeting, received an award of 750 restricted stock units of the Fund. Non-employee directors also received dividend equivalents in respect of such restricted stock units equal to the amount or value of any cash or other dividends or distributions payable on an equivalent number of shares of Common

16

Stock. The restricted stock units and related dividend equivalents vest (and become non-forfeitable) and are paid (in the form of shares of Common Stock) one year from the date of grant.

Employee Thrift Plans

Employees of the Fund who have completed six months of service may defer up to 100% of base salary and cash incentive compensation to a tax qualified thrift plan instead of being paid currently, and the Fund contributes an amount equal to 100% of each employee’s contribution (up to 6% of base salary and cash incentive compensation) but not in excess of the maximum permitted by law (see footnotes to the Compensation Table set forth on page 14 regarding 2015 contributions for the officers identified therein). The Fund also has the discretion to contribute annually to each employee’s thrift plan account an amount of up to 6% of the employee’s combined base salary and cash incentive compensation attributable to the prior year’s service with the Fund. All employee contributions are credited to the employee’s individual account. Employees may elect that their salary deferral and other contributions be invested in Common Stock of the Fund, or of PEO, or a number of mutual funds, or a combination thereof. All of the Fund’s matching contribution is invested in accordance with the employee’s investment elections, provided that the employee is 100% vested in the Employee Thrift Plan. An employee’s interest in amounts derived from the Fund’s contributions becomes non-forfeitable upon completion of 36 months of service or upon death or retirement. Payments of amounts not withdrawn or forfeited under the thrift plan may be made upon retirement or other termination of employment in a single distribution, in equal installments, or in an annuity.

The Fund also maintains an Executive Nonqualified Supplemental Thrift Plan for eligible employees of the Fund (the “Nonqualified Plan”). The purpose of the Nonqualified Plan is to provide deferred compensation in excess of contribution limits imposed by the Internal Revenue Code on tax-qualified thrift plans, including the Employee Thrift Plan of the Fund described above. In accordance with such limitations, for 2016, the maximum annual amount that an individual can defer to all tax-qualified thrift plans offered by the Fund is $18,000 for those under the age of 50, and $24,000 for those age 50 and over, and the maximum combined amount – consisting of both the employee’s contributions and the Fund’s matching contributions – that can go into any single tax-qualified thrift plan is $53,000 per year for those under the age of 50 and $59,000 per year for those age 50 and over.

The Nonqualified Plan permits an eligible employee to contribute to the Nonqualified Plan up to the maximum amount of 6% of the employee’s salary and cash incentive compensation that he or she is prevented from contributing to the tax-qualified thrift plan because of the Internal Revenue Code’s limitations on annual contributions, and for the Fund to contribute the 100% matching contribution on that sum and/or the Fund’s discretionary contribution that would otherwise be limited by the Internal Revenue Code’s limitations on annual contributions. The employee’s contributions and the Fund’s contributions to the Nonqualified Plan are invested in eligible mutual funds in accordance with the employee’s investment elections.

Employee Retirement Plans

The Fund offered an Employees’ Retirement Plan that was terminated and the assets were distributed to Participants in May 2015. Under the plan, employees of the Fund with one or more years of service as of October 1, 2009, participated in a retirement plan pursuant to which contributions were made solely by the Fund on behalf of, and benefits are provided for, employees meeting certain age and service requirements. The benefits under the plan were frozen as of October 1, 2009, and no additional benefits attributable to additional years of service or increases in

17

annual cash compensation after that date were recognized. In connection with the termination of the Employees’ Retirement Plan, distributions in the amounts of $0, $0, and $565,259 were made to Messrs. Stoeckle, Haynie, and Swindell, respectively.

The Fund also maintained a supplemental retirement benefits plan (the “Supplemental Plan”) for employees of the Fund that was terminated and the assets were distributed to Participants in June 2015. The purpose of the Supplemental Plan was to provide deferred compensation in excess of benefit limitations imposed by the Internal Revenue Code on tax-qualified defined benefit plans, including the retirement plan of the Fund described above. In connection with the termination of Supplemental Plan, distributions in the amounts of $0, $0, and $51,286 were made to Messrs. Stoeckle, Haynie, and Swindell, respectively.

Brokerage Commissions

During the past fiscal year, the Fund paid brokerage commissions in the amount of $381,683 on the purchase and sale of portfolio securities traded on the New York Stock Exchange and the National Association of Securities Dealers Automated Quotation System, substantially all of which were paid to brokers providing research and other investment services to the Fund and on options written or purchased by the Fund. The average per share commission rate paid by the Fund was $0.03. No commissions were paid to an affiliated broker.

Portfolio Turnover

The portfolio turnover rate (purchases or sales, whichever is lower, as a percentage of weighted average portfolio value) for the past three years has been as follows:

2015	2014	2013
22.0%	26.6%	55.9%

Expense Ratio

The ratio of expenses to the average net assets of the Fund for the past three years has been as follows:

2015	2014	2013
0.96%*	0.58%	0.69%

* Excluding non-recurring charge for termination of the defined benefit retirement plans, the ratio was 0.67%.

(2) RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

As permitted under the Act, the Audit Committee has selected PricewaterhouseCoopers LLP, 100 E. Pratt Street, Baltimore, Maryland, an independent registered public accounting firm, as the independent registered public accounting firm to audit the books and accounts of the Fund for or during the year ending December 31, 2016. PricewaterhouseCoopers LLP was the Fund’s principal auditor during the year 2015. A majority of the members of the Board of Directors who are not “interested persons” (as defined by the Act) have ratified the selection of PricewaterhouseCoopers LLP as the Fund’s independent registered public accounting firm for 2016. While not required under the Act, the Audit Committee and the Board of Directors have determined to submit for stockholder ratification the selection of PricewaterhouseCoopers LLP as the Fund’s independent registered public accounting firm for 2016 at the Annual Meeting. Representatives of PricewaterhouseCoopers LLP are

18

expected to be present at the meeting to make a statement if they so desire and to respond to appropriate questions. The Fund has been informed that PricewaterhouseCoopers LLP does not have any direct financial or any material indirect financial interest in the Fund.

The Board of Directors unanimously recommends ratification of the selection of PricewaterhouseCoopers LLP.

(3) OTHER MATTERS AND ANNUAL REPORT

As of the date of this proxy statement, management knows of no other business that will come before the meeting. Should other business be properly brought up, it is intended that proxies in the accompanying form will be voted thereon in accordance with the judgment of the person or persons voting such proxies.

The Annual Report of the Fund for the year ended December 31, 2015, including financial statements, is being mailed to all stockholders entitled to notice of and to vote at the Annual Meeting to be held on April 14, 2016. A copy of the Fund’s Annual Report will be furnished to stockholders, without charge, upon request. You may request a copy by contacting Lawrence L. Hooper, Jr., Vice President, General Counsel and Secretary, at 500 East Pratt Street, Suite 1300, Baltimore, MD 21202, by telephoning Mr. Hooper at (800) 638-2479, or by sending Mr. Hooper an e-mail message at contact@adamsfunds.com.

The Fund has retained AST Fund Solutions, LLC to assist in the solicitation of proxies. The Fund will pay AST Fund Solutions, LLC a fee for its services, not to exceed $2,500, and will reimburse AST Fund Solutions, LLC for its expenses, which the Fund estimates should be approximately $1,500.

Stockholder Proposals or Nominations for 2017 Annual Meeting

Stockholder proposals for inclusion in the proxy statement and form of proxy relating to the 2017 Annual Meeting must be received at the office of the Fund, 500 East Pratt Street, Suite 1300, Baltimore, MD 21202, no later than October 26, 2016.

In addition, for stockholder proposals or director nominations that a stockholder seeks to bring before the 2017 Annual Meeting but does not seek to have included in the Fund’s proxy statement and form of proxy for that meeting, the following requirements apply: Pursuant to the Fund’s Bylaws, in order for stockholder proposals or nominations of persons for election to the Board of Directors to be properly brought before the 2017 Annual Meeting, any such stockholder proposal or nomination (including in the case of a nomination, the information required by the Fund’s advance notice Bylaws provisions) must be received at the office of the Fund no earlier than September 26, 2016 and no later than October 26, 2016. The Fund’s advance notice Bylaw requirements are separate from, and in addition to, the Commission’s requirements (including the timing requirements described in the preceding paragraph) that a stockholder must meet in order to have a stockholder proposal included in the proxy statement. Should the Fund determine to allow a stockholder proposal that is received by the Fund after October 26, 2016 to be presented at the 2017 Annual Meeting, the persons named as proxies in the form accompanying the proxy statement for such meeting will have discretionary voting authority with respect to such stockholder proposal.
