Proxy Statement

Information Concerning Voting and Solicitation

General

This Proxy Statement is furnished in connection with the solicitation by the Board of Directors (the “Board”) of Digital Realty Trust, Inc., a Maryland corporation (the “Company”), of proxies to be exercised at the 2017 Annual Meeting of Stockholders (the “Annual Meeting”) to be held on Monday, May 8, 2017, at 9:00 a.m. PDT, or at any postponement(s) or adjournment(s) thereof, for the purposes discussed in this Proxy Statement and in the accompanying Notice of 2017 Annual Meeting of Stockholders. Proxies are solicited to give all stockholders of record at the close of business on March 14, 2017 (the “Record Date”) an opportunity to vote on matters properly presented at the Annual Meeting. The Annual Meeting will be held at Four Embarcadero Center, Third Floor, Promenade Level conference center (Stanford Room), San Francisco, CA 94111.

Pursuant to the rules of the United States Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials over the Internet. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials (a “Notice”) to our stockholders of record, while brokers and other nominees who hold shares on behalf of beneficial owners will be sending their own similar Notice. All stockholders will have the ability to access proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to request a printed copy by mail or electronically may be found on the Notice and on the website referred to in the Notice, including an option to request paper copies on an ongoing basis. We intend to make this Proxy Statement available on the Internet on or about March 29, 2017 and to mail the Notice to all stockholders entitled to vote at the Annual Meeting on or about March 29, 2017. We intend to mail this Proxy Statement, together with a proxy card, to those stockholders entitled to vote at the Annual Meeting who have properly requested paper copies of such materials on or about March 29, 2017 or within three business days of such request.

Who Can Vote

You are entitled to vote if you were a stockholder of record of the Company’s Common Stock, par value $0.01 per share (the “Common Stock”), as of the Record Date. Your shares can be voted at the Annual Meeting only if you are present in person or represented by a valid proxy.

Quorum

A majority of the outstanding shares of Common Stock as of the Record Date represented in person or by proxy will constitute a quorum at the Annual Meeting. As of the Record Date, 159,458,209 shares of Common Stock were outstanding.

Voting of Shares

Stockholders of record as of the Record Date are entitled to one vote for each share of Common Stock held on all matters to be voted upon at the meeting. You may vote by attending the Annual Meeting and voting in person. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote in person at the meeting, you must obtain a proxy issued in your name from such broker, bank or other nominee. If you choose not to attend the Annual Meeting, you may still authorize your proxy via the Internet, by telephone or by mailing a proxy card.

All shares entitled to vote and represented by properly executed proxies received before the polls are closed at the Annual Meeting, and not revoked or superseded, will be voted at the Annual Meeting in accordance with the instructions indicated on those proxies. YOUR VOTE IS IMPORTANT.

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    7

Proxy Card and Revocation of Proxy

If you sign a proxy card but do not specify how you want your shares to be voted, your shares will be voted by the proxy holders named in the enclosed proxy:

• FOR the election of all of the director nominees;

• FOR ratifying the selection of KPMG LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2017;

• FOR the resolution approving, on a non-binding, advisory basis, the compensation of the Company’s named executive officers (“say-on-pay”); and

• FOR the approval, on a non-binding, advisory basis, of an annual say-on-pay vote.

In their discretion, the proxy holders named in the enclosed proxy are authorized to vote on any other matters that may properly come before the Annual Meeting and at any postponement(s) or adjournment(s) thereof. The Board knows of no other items of business that will be presented for consideration at the Annual Meeting other than those described in this Proxy Statement.

If you vote your shares by authorizing a proxy, you may revoke your proxy authorization at any time before it is voted at the Annual Meeting. You may revoke your proxy by sending to the Company’s Secretary at the Company’s principal executive office at Four Embarcadero Center, Suite 3200, San Francisco, CA 94111, a written notice of revocation, or by delivering by mail, by telephone, via the Internet or in person a duly executed proxy bearing a later date, or by attending the Annual Meeting in person and voting in person. Attendance at the meeting will not, by itself, revoke a proxy.

Counting of Votes

All votes will be tabulated by the inspector of election appointed for the Annual Meeting, who will separately tabulate affirmative and negative votes and abstentions. Shares held by persons attending the Annual Meeting but not voting, shares represented by proxies that reflect abstentions as to a particular proposal and broker “non-votes” will be counted as present for purposes of determining a quorum. A broker “non-vote” occurs when a nominee holding shares for a beneficial owner has not received instructions from the beneficial owner and chooses not to exercise or does not have discretionary authority to vote the shares on a particular matter because the matter is not routine under the New York Stock Exchange (“NYSE”) rules. The election of the Board’s nominees named herein, the proposal to approve, on a non-binding, advisory basis, the compensation of the Company’s named executive officers, and the vote, on a non-binding, advisory basis, on the frequency of future say-on-pay votes are not routine matters under the NYSE rules.

The affirmative vote of a majority of the votes cast at the Annual Meeting at which a quorum is present is required for the election of each director nominee. For purposes of the election of directors, a majority of the votes cast means that the number of votes cast “for” a nominee for election as a director exceeds the number of votes cast “against” that nominee. For purposes of calculating votes cast in the election of directors, abstentions and broker non-votes will not be counted as votes cast and will have no effect on the result of the vote on the election of the directors.

The affirmative vote of a majority of the votes cast at the Annual Meeting at which a quorum is present is required for ratifying the selection of KPMG LLP as our independent registered public accounting firm. For purposes of the vote on ratifying the selection of KPMG LLP as our independent registered public accounting firm, abstentions and broker non-votes will not be counted as votes cast and will have no effect on the result of the vote. The selection of KPMG LLP as our independent registered public accounting firm is a routine matter under the NYSE rules and a nominee holding shares for a beneficial owner will have discretionary authority to vote on this proposal absent instructions from the beneficial owner.

The affirmative vote of a majority of the votes cast at the Annual Meeting at which a quorum is present is required to adopt the resolution approving, on a non-binding, advisory basis, the compensation of our named executive officers. For purposes of the vote on the resolution approving the compensation of our named executive officers, abstentions and broker non-votes will not be counted as votes cast and will have no effect on the result of the vote.

The affirmative vote of a majority of the votes cast at the Annual Meeting at which a quorum is present is required to adopt the resolution approving, on a non-binding, advisory basis, the frequency of future say-on-pay votes (a “say-on-frequency” vote). For purposes of the say-on-frequency vote, the frequency receiving a majority of votes cast (every one, two or three years) will be considered the frequency recommended by stockholders. In the event that no option receives a majority of the votes cast, we will consider the option that receives the most votes to be the option selected by the stockholders. For purposes of the say-on-frequency vote, abstentions and broker non-votes will have no effect on the result of the vote.

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    8

Solicitation of Proxies

We will bear the entire cost of soliciting proxies. We may reimburse banks, brokerage houses, fiduciaries and custodians holding shares of our Common Stock in their names for their expenses incurred in forwarding the solicitation materials to beneficial owners. Solicitation of proxies may be supplemented by telephone, facsimile, electronic mail or personal solicitation by directors, officers or employees of the Company. No additional compensation will be paid to directors, officers or employees for such services.

Attendance at the Annual Meeting

In order to attend the Annual Meeting, you will need proof of ownership of our Common Stock as of the Record Date. If you hold your shares in street name (such as through a bank, broker or other nominee), you should bring your statement showing your beneficial ownership of our Common Stock in order to be admitted to the meeting and you must obtain a proxy issued in your name from such bank, broker or other nominee if you wish to vote in person at the meeting.

NO PERSON IS AUTHORIZED ON BEHALF OF THE COMPANY TO GIVE ANY INFORMATION OR TO MAKE ANY REPRESENTATIONS WITH RESPECT TO THE PROPOSALS OTHER THAN THE INFORMATION AND REPRESENTATIONS CONTAINED IN THIS PROXY STATEMENT, AND, IF GIVEN OR MADE, SUCH INFORMATION AND/OR REPRESENTATIONS MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED. THE DELIVERY OF THIS PROXY STATEMENT SHALL UNDER NO CIRCUMSTANCES CREATE ANY IMPLICATION THAT THERE HAS BEEN NO CHANGE IN THE AFFAIRS OF THE COMPANY SINCE THE DATE HEREOF.

The Company’s principal executive office is located at Four Embarcadero Center, Suite 3200, San Francisco, CA 94111, our telephone number is (415) 738-6500 and our website is www.digitalrealty.com.* References herein to the “Company” refer to Digital Realty Trust, Inc. and its subsidiaries, unless the context otherwise requires.

ITEM 1. Election of Directors

Under the Company’s charter and Sixth Amended and Restated Bylaws (the “Bylaws”), each member of the Board serves until the next annual meeting of stockholders and until his or her successor is duly elected and qualifies or until his or her earlier death, resignation or removal. Vacancies on the Board may be filled only by individuals elected by the affirmative vote of a majority of the remaining directors, even if the remaining directors do not constitute a quorum. A director elected by the Board to fill a vacancy (including a vacancy created by an increase in the size of the Board) will serve for the remainder of the full term of the directorship and until such director’s successor is duly elected and qualifies, or until such director’s earlier death, resignation or removal.

Our Bylaws require that, in order to be elected in an uncontested election, a director receive a majority of votes cast by holders of the shares present in person or represented by proxy with respect to such director at a meeting at which a quorum is present. A majority of the votes cast means that the number of shares voted “for” a director must exceed the number of votes “against” that director. In a contested election (where a determination is made that the number of director nominees is expected to exceed the number of directors to be elected at a meeting), directors will be elected by a plurality of the votes cast, which means the nine nominees who receive the largest number of properly cast votes will be elected as directors.

Any director who fails to be elected by a majority vote shall tender his or her resignation to the Board, subject to acceptance. The Nominating and Corporate Governance Committee will make a recommendation to the Board on whether to accept or reject the resignation, or whether other action should be taken. The Board will then act on the Nominating and Corporate Governance Committee’s recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date of the certification of election results. If the resignation is not accepted, the director will continue to serve until the next annual meeting and until the director’s successor is duly elected and qualifies. The director who tenders his or her resignation will not participate in the Board’s decision regarding whether to accept or reject such director’s resignation.

Each share of Common Stock is entitled to one vote for each of the nine director nominees. Cumulative voting is not permitted. It is the intention of the proxy holders named in the enclosed proxy to vote the proxies received by them for the election of the nominees named below unless instructed otherwise. If any nominee should become unavailable for election prior to the Annual Meeting, an event which currently is not anticipated by the Board, the proxies will be voted for the election of a substitute nominee or nominees proposed by the Board.

Dennis E. Singleton, Laurence A. Chapman, Kathleen Earley, Kevin J. Kennedy, William G. LaPerch, Afshin Mohebbi, Mark R. Patterson, A. William Stein and Robert H. Zerbst are all of our nominees for election to the Board. Each nominee has consented to be named in this Proxy Statement and to serve as a director if elected, and management has no reason to believe that any nominee will be unable to serve. The information below relating to the nominees for election as director has been furnished to the Company by the respective individuals.

Board Governance Documents

The Board maintains charters for all its committees. In addition, the Board has adopted a written set of Corporate Governance Guidelines, as well as a Code of Business Conduct and Ethics that applies to the Company’s employees, officers and directors, including our principal executive officer and principal financial officer. To view the charters of our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee, Corporate Governance Guidelines and Code of Business Conduct and Ethics, please visit our website at www.digitalrealty.com. Each of these documents is also available, free of charge, in print to any stockholder who sends a written request to Joshua A. Mills, Secretary, Digital Realty Trust, Inc., Four Embarcadero Center, Suite 3200, San Francisco, CA 94111.

Independent Directors

NYSE listing standards require NYSE-listed companies to have a majority of independent board members and an audit committee, compensation committee and nominating and corporate governance committee each composed solely of independent directors. Under the NYSE listing standards, no director of a company qualifies as “independent” unless the board of directors of such company affirmatively determines that the director has no material relationship with such company (either directly or as a partner, stockholder or officer of an organization that has a relationship with such company).

In addition, the NYSE listing standards provide that a director is not independent if:

(i)	the director is, or has been within the last three years, an employee of the listed company, or an immediate family member is, or has been within the last three years, an executive officer of the listed company;
(ii)	the director has received, or has an immediate family member who has received, during any twelve-month period within the last three years, more than $120,000 in direct compensation from the listed company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service);
(iii)	(A) the director is a current partner or employee of a firm that is the company’s internal or external auditor;

	(B) the director has an immediate family member who is a current partner of such a firm; (C) the director has an immediate family member who is a current employee of such a firm and personally works on the listed company’s audit; or (D) the director or an immediate family member was within the last three years a partner or employee of such a firm and personally worked on the listed company’s audit within that time;
(iv)	the director or an immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of the listed company’s present executive officers at the same time serves or served on that company’s compensation committee; or
(v)	the director is a current employee, or an immediate family member is a current executive officer, of a company that has made payments to, or received payments from, the listed company for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million or 2% of such other company’s consolidated gross revenues.

The Board by resolution has affirmatively determined that, based on the standards set forth in the NYSE rules and our corporate governance documents, all nominees for election to the Board at the Annual Meeting are independent (the “Independent Directors”).

Board Meetings

The Board held seven meetings and the Independent Directors met in executive session four times during 2016. During 2016, Mr. Singleton, as the Chairman of the Board, served as the presiding director of the executive sessions of the Independent Directors. The number of meetings held during 2016 for each Board committee is set forth below under the heading “Board Committees.” During the year ended December 31, 2016, each of the directors attended at least 75% of the total number of meetings of the Board and of the committees on which he or she served. All of the then-current directors attended the 2016 Annual Meeting, and the Board expects all current directors standing for re-election to the Board to attend the 2017 Annual Meeting barring unforeseen circumstances or irresolvable conflicts.

Board Leadership Structure

We separate the roles of Chief Executive Officer and Chairman of the Board in recognition of the differences between the two roles. The Chief Executive Officer is responsible for setting the strategic direction for the Company and the day-to-day leadership and performance of the Company, while the Chairman of the Board provides guidance to the Chief Executive Officer and sets the agenda for Board meetings and presides over meetings of the full Board and executive sessions of the Independent Directors. This separation of the roles of Chairman and Chief Executive Officer allows for greater oversight of the Company by the Board. In July 2016, the Board approved the appointment of Laurence A. Chapman as Vice Chairman of the Board. The Board has determined that our Board leadership structure is the most appropriate at this time, given the specific characteristics and circumstances of the Company, and the skills and experience of Mr. Singleton, Mr. Chapman and Mr. Stein. As previously announced and as part of succession planning, the Board expects to appoint Mr. Chapman as Chairman of the Board immediately following the 2017 Annual Meeting.

Audit Committee

We have a separately designated standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The function of the Audit Committee is to assist the Board with its oversight responsibilities regarding: (i) the integrity of the Company’s financial statements; (ii) the Company’s compliance with legal and regulatory requirements; (iii) the qualifications, engagement, compensation, and independence of the registered public accounting firm that audits the Company’s financial statements (the “independent auditor”); and (iv) the performance of the Company’s internal audit function and independent auditor. The Audit Committee also prepares the disclosure required by federal securities laws, including Item 407(d)(3)(i) of Regulation S-K, to be included in the Company’s annual Proxy Statement. The Audit Committee is directly responsible and has sole authority for the appointment, compensation, retention, termination, evaluation and oversight of the work of the independent auditor for the purpose of preparing or issuing an audit report or related work or performing other audit, review or attest services for the Company. In addition, the Audit Committee is responsible for reviewing, at least annually, the independence, performance, qualifications and quality control procedures of the independent auditor and the experience and qualifications of the independent auditor’s senior personnel, and is responsible for overseeing the annual audit, quarterly review, and internal audit.

The Audit Committee carries out its responsibilities in accordance with the terms of our Audit Committee Charter, which is located on our website at www.digitalrealty.com and is available in print to any stockholder who requests it by writing to our Secretary, as provided for in “— Board Governance Documents.” Mr. Chapman is Chair and Ms. Earley and Messrs. Mohebbi and Patterson are members of the Audit Committee. Mr. Kennedy also served on the Audit Committee during 2016. The Board has determined that Mr. Chapman is an “audit committee financial expert” as defined by the SEC. The Audit Committee meets the NYSE

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    20

composition requirements, including the requirements dealing with financial literacy and financial sophistication. The Audit Committee is composed of Independent Directors under the current NYSE listing standards. Such directors also satisfy the independence requirements of Section 10A-3(m) of the Exchange Act and Rule 10A-3(b)(i). During 2016, the Audit Committee met five times.

Before the Company’s independent auditor is engaged by the Company or its subsidiaries to render audit or non-audit services, the Audit Committee is required to pre-approve the engagement. Audit Committee pre-approval of audit and non-audit services will not be required if the engagement for the services is entered into pursuant to pre-approval policies and procedures established by the Audit Committee regarding the Company’s engagement of the independent auditor, provided the policies and procedures are detailed as to the particular service, the Audit Committee is informed of each service provided and such policies and procedures do not include delegation of the Audit Committee’s responsibilities under the Exchange Act to the Company’s management. Audit Committee pre-approval of non-audit services (other than review and attest services) also will not be required if such services fall within available exceptions established by the SEC. The Audit Committee may delegate to one or more designated members of the Audit Committee the authority to grant pre-approvals, provided such approvals are presented to the Audit Committee at a subsequent meeting. The Audit Committee delegated the authority to grant pre-approvals to Mr. Chapman, the Chair of the Audit Committee.

Information regarding the specific functions performed by the Audit Committee is set forth below in “Audit Matters — Audit Committee Report.”

Compensation Committee

We have a standing Compensation Committee, whose function is to discharge or assist the Board in discharging the Board’s responsibilities relating to compensation of the Company’s executives, including by designing (in consultation with the Company’s management), approving, recommending to the Board for approval, implementing, administering, managing and evaluating the compensation plans, policies and programs of the Company. The Compensation Committee reviews, at least annually, the compensation of our executive officers and approves the compensation of our named executive officers. In addition, the Compensation Committee reviews and approves, at least annually, the corporate goals and objectives relating to the compensation of our Chief Executive Officer and evaluates his performance relative to these goals. The Compensation Committee also prepares the disclosure required by federal securities laws to be included in the Company’s annual Proxy Statement and administers the Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2014 Incentive Award Plan, as amended (the “2014 Plan”), which replaced the First Amended and Restated Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2004 Incentive Award Plan, as amended (the “2004 Plan”).

Our Compensation Committee Charter is located on our website at www.digitalrealty.com and is available in print to any stockholder who requests it by writing to our Secretary, as provided for in “— Board Governance Documents.” Mr. Zerbst is Chair and Ms. Earley and Messrs. Kennedy, Patterson and Singleton are members of the Compensation Committee. All members of the Compensation Committee are Independent Directors. Messrs. Chapman and LaPerch also served on the Compensation Committee during 2016. The Board by resolution also affirmatively determined that none of the members of our Compensation Committee had any relationship to the Company which was material to that director’s ability to be independent from management in connection with the duties of a compensation committee member. Such directors also satisfy the independence requirements of Section 10C(a) of the Exchange Act and Rule 10C-1(b)(1). During 2016, the Compensation Committee met seven times.

The Compensation Committee exercises all powers delegated to it by the Board related to compensation matters, including approval of incentive compensation and oversight of benefit plans for employees of the Company. The Compensation Committee has authority to grant awards under our 2014 Plan. The Compensation Committee is primarily responsible for determining cash and non-cash compensation for our Chief Executive Officer, Chief Financial Officer and other named executive officers.

In fulfilling its responsibilities, the Compensation Committee may delegate any or all of its responsibilities to a subcommittee of the Compensation Committee, except for:

• the review and approval of the corporate goals and objectives relating to the compensation of our Chief Executive Officer and the evaluation of his performance relative to these goals;

• the review and approval of compensation for our Chief Executive Officer, Chief Financial Officer and all other named executive officers;

• the recommendations to the Board with respect to non- CEO compensation, incentive compensation plans and equity-based plans and the review and approval of all executive officers’ employment agreements and severance arrangements;

• the management and review of all annual bonus, long- term incentive compensation, equity compensation and employee benefit plans; and

• any matters that involve executive compensation or any matters where the Compensation Committee has determined such compensation is intended to comply with Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), by virtue of being approved by a committee of “outside directors” or is intended to be exempt from Section 16(b) under the Exchange Act pursuant to Rule 16b-3 by virtue of being approved by a committee of “non-employee directors.”

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    21

To aid the Compensation Committee in making its determinations, management provides recommendations annually to the Compensation Committee regarding the compensation of all named executive officers. Each named executive officer participates in an annual performance review either with the Compensation Committee, with input from the Board, in the case of our Chief Executive Officer, or with our Chief Executive Officer, in the case of all other named executive officers, to obtain input about their contributions to our success for the period being assessed. The performance of our named executive officers is also reviewed annually by the Compensation Committee.

For 2016, the Compensation Committee retained the services of FPL Associates L.P. (“FPL”) to serve as the Compensation Committee’s independent compensation consultant. FPL was engaged to assist the Compensation Committee with a variety of tasks, which included among other things, conducting and presenting the annual review of the total compensation packages for our executive officers, including base salary, cash bonuses, long-term incentives and total direct compensation; reviewing market data on compensation; reviewing and assessing the long-term incentives currently provided to executives and future awards; aligning and testing performance-related pay; reviewing non-employee directors’ compensation; and understanding market trends. The Compensation Committee assessed the independence of FPL pursuant to the rules prescribed by the SEC and the NYSE and concluded that no conflict of interest existed in 2016 that would prevent FPL from serving as an independent consultant to the Compensation Committee.

Nominating and Corporate Governance Committee

We have a standing Nominating and Corporate Governance Committee, whose function is to assist the Board in discharging the Board’s responsibilities regarding (i) the identification of qualified candidates to become Board members; (ii) the selection of nominees for election as directors; (iii) the selection of candidates to fill any vacancies on the Board; (iv) the development and recommendation to the Board of a set of corporate governance guidelines and principles applicable to the Company; and (v) oversight of the evaluation of the Board and management.

Our Nominating and Corporate Governance Committee Charter is located on our website at www.digitalrealty.com and is available in print to any stockholder who requests it by writing to our Secretary, as provided for in “— Board Governance Documents.” Mr. LaPerch is Chair and Messrs. Chapman, Kennedy, Mohebbi and Singleton are members of the Nominating and Corporate Governance Committee. Ms. Earley also served on the Nominating and Corporate Governance Committee during 2016. All members of the Nominating and Corporate Governance Committee are Independent Directors. During 2016, the Nominating and Corporate Governance Committee met five times. Further information regarding the Nominating and Corporate Governance Committee is set forth below in “— Qualifications of Director Nominees,” “— Nominating and Corporate Governance Committee’s Process for Considering Director Nominees” and “— Manner by which Stockholders May Recommend Director Nominees.”

Qualifications of Director Nominees

The Nominating and Corporate Governance Committee has not set forth minimum qualifications for Board nominees. Pursuant to its charter, in identifying candidates to recommend for election to the Board, the Nominating and Corporate Governance Committee considers the following criteria:

(i)	personal and professional integrity, ethics and values;
(ii)	experience in corporate governance including as an officer, board member or senior executive or as a former officer, board member or senior executive of a publicly held company, and a general understanding of marketing, finance and other elements relevant to the success of a publicly traded company in today’s business environment;
(iii)	experience as a board member of another publicly held company;
(iv)	academic, executive and/or operational expertise in an area of the Company’s industry or operations;
(v)	practical and mature business judgment, including ability to make independent analytical inquiries; and
(vi)	ability to work as part of a team.

While the Nominating and Governance Committee does not have a formal policy regarding diversity, the Company’s Corporate Governance Guidelines state that each individual nominee is evaluated in the context of the Board as a whole, with the objective of assembling a group that can best perpetuate the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas. The Committee considers diversity of the Board in identifying director nominees, including diversity in experience, professional background, areas of expertise and industries of the candidate.

Nominating and Corporate Governance Committee’s Process for Considering Director Nominees

The Nominating and Corporate Governance Committee periodically reviews the performance of each current director and considers the results of such evaluation when determining whether to recommend the nomination of such director for an additional term. At an appropriate time prior to each annual meeting at which directors are to be elected or re-elected, the Nominating and Corporate Governance Committee recommends to the Board for nomination by the Board such candidates as the Nominating and Corporate Governance Committee, in the exercise of its judgment, has found to be well qualified and willing and available to serve.

At an appropriate time after a vacancy arises on the Board or a director advises the Board of his or her intention to resign, the Nominating and Corporate Governance Committee recommends to the Board for election by the Board to fill such vacancy, such prospective member of the Board as the Nominating and Corporate Governance Committee, in the exercise of its judgment, has found to be well qualified and willing and available to serve. In determining whether a prospective member is qualified to serve, the Nominating and Corporate Governance Committee will consider the factors listed above in “— Qualifications of Director Nominees.”

The foregoing notwithstanding, if the Company is legally required by contract or otherwise to permit a third party to designate one or more of the director nominees to be elected (for example, pursuant to rights contained in the Articles Supplementary of each class of our outstanding preferred stock, voting together, to elect two directors upon a dividend default), then the nomination or election of such directors will be governed by such requirements. Additionally, recommendations received from stockholders will be considered and are subject to the same criteria as are candidates nominated by the Nominating and Corporate Governance Committee.

Manner by Which Stockholders May Recommend Director Nominees

The Nominating and Corporate Governance Committee will consider director nominees recommended by stockholders of the Company. All recommendations must be directed to William G. LaPerch, Chair of the Nominating and Corporate Governance Committee, care of Joshua A. Mills, Secretary, Digital Realty Trust, Inc., Four Embarcadero Center, Suite 3200, San Francisco, California 94111. Recommendations for director nominees to be considered at the 2018 Annual Meeting must be received in writing not later than 5:00 p.m., Pacific Time, on November 29, 2017 and not earlier than October 30, 2017. In the event that the date of the 2018 Annual Meeting is advanced or delayed by more than 30 days from the first anniversary of the date of the 2017 Annual Meeting, notice by the stockholder must be received not earlier than the 150^th day prior to the date of the meeting and not later than 5:00 p.m., Pacific Time, on the later of the 120^th day prior to the date of the meeting, as originally convened, or the 10^th day following the date of the first public announcement of the meeting. Each stockholder recommending a person as a director candidate must provide the Company with the information specified in our Bylaws, as described under “Other Matters — Stockholder Proposals and Nominations” below. The recommending stockholder must also provide supplemental information that the Nominating and Corporate Governance Committee may request to determine whether the proposed nominee (i) is qualified to serve on the Audit Committee, (ii) meets the standards of an independent director and (iii) satisfies the standards for our directors set forth above in “— Qualifications of Director Nominees.” Further, the proposed nominee must make himself or herself reasonably available to be interviewed by the Nominating and Corporate Governance Committee. Please refer to “Other Matters — Stockholder Proposals and Nominations” below for further information. The Nominating and Corporate Governance Committee will consider all recommended director candidates submitted to it in accordance with these established procedures, though it will only recommend to the Board as potential nominees those candidates it believes are most qualified. However, the Nominating and Corporate Governance Committee will not consider any director candidate if the candidate’s candidacy or, if elected, Board membership, would violate controlling state law or federal law.

Board’s Role in Oversight of Risk

The Board has an active role in overseeing management of the Company’s risks, and the Company’s management regularly provides it with reports highlighting its assessments and recommendations. The Board regularly reviews information from members of senior management regarding the Company’s financial performance, balance sheet, credit profile and liquidity, as well as the risks associated with each. The Board also receives reports from members of management on areas of material risk to the Company, including operational, financial, legal, regulatory, cybersecurity and strategic risks. The Compensation Committee assesses and monitors risks relating to the Company’s executive officer and employee compensation policies and practices. The Audit Committee oversees management of financial reporting and internal controls risks. The Nominating and Corporate Governance Committee is responsible for overseeing the management of risks associated with the independence of the Board and corporate governance.

ITEM 2.  Ratification of Selection of Independent Registered Public Accounting Firm

The Audit Committee of the Board has selected KPMG LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2017 and has further directed that management submit the selection of KPMG LLP for ratification by the stockholders at the Annual Meeting. KPMG LLP has audited the Company’s financial statements since the Company’s inception in 2004. Representatives of KPMG LLP are expected to be present at the Annual Meeting and will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Stockholder ratification of the selection of KPMG LLP as the Company’s independent registered public accounting firm is not required by the Bylaws or otherwise. However, the Board is submitting the selection of KPMG LLP to the stockholders for ratification as a matter of corporate practice. If the stockholders fail to ratify the selection, the Audit Committee may reconsider whether or not to retain KPMG LLP in the future. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interests of the Company.

The affirmative vote of a majority of the votes cast at the Annual Meeting is required to ratify the selection of KPMG LLP as our independent registered public accounting firm.

Executive Compensation

Compensation Discussion and Analysis

This Compensation Discussion and Analysis section discusses the compensation policies and programs for our named executive officers, as determined under the rules of the SEC, for fiscal year 2016. The following table identifies our named executive officers and their positions in 2016:

Name	Position
A. William Stein	Chief Executive Officer
Andrew P. Power	Chief Financial Officer
Jarrett B. Appleby	Chief Operating Officer
Scott E. Peterson	Chief Investment Officer
Joshua A. Mills	Senior Vice President, General Counsel and Secretary
Matthew J. Miszewski	Former Senior Vice President, Global Sales and Marketing

Mr. Miszewski departed the Company effective as of August 15, 2016.

Executive Summary

The objective of our executive compensation program is to attract, retain and motivate experienced and talented executives who can help maximize stockholder value. We believe that a significant portion of the compensation paid to executive officers should be closely aligned with our performance on both a short-term and long-term basis.

The total compensation opportunity for each of our named executive officers, including targets for performance-based compensation, was set by the Compensation Committee in late 2015 and early 2016. The Compensation Committee utilized the services of FPL Associates L.P. (“FPL”) for this compensation review, which included reviewing compensation information of our peer group.

We maintain a competitive compensation program with the following components:

Component	Link to Program Objectives	Type of Compensation	Description
Base Salary	Fixed level of cash compensation to support attraction and retention of key executive officers in a competitive marketplace	Cash	Determined based on evaluation of individual’s experience and current performance, internal pay equity and a comparison to salaries of similarly-situated executive officers in our peer group
Annual Cash Bonus	Cash incentive opportunity (set as a percentage of base salary) that encourages executive officers to achieve annual Company, business unit and individual goals Assists in retaining, attracting and motivating employees in the near term	Cash	Earned based on the attainment of a combination of corporate/financial and individual performance goals Specific Company performance measures include core FFO per share (measuring earnings), leasing (measuring strategic/portfolio performance), and Adjusted EBITDA margin (measuring profitability) A variety of specific, individual and departmental goals
Long-Term Incentive Program	Focuses executive officers on creating long-term stockholder value and directly aligns interests with that of stockholders Easy to understand and track performance Provides additional retention	Profits Interests Units/Restricted Stock Units	Three-year performance period with actual performance-vesting of units at 0% to 200% of target based entirely on relative total stockholder return over the performance period 50% time-vests upon the conclusion of the performance period and 50% time-vests one year thereafter

2016 Compensation Highlights

The following summarizes key aspects of our compensation policies and programs:

What We Do:
	We Pay for Performance: We pay for performance, and our compensation programs are designed to have direct alignment with total stockholder return performance; salaries comprise a relatively modest portion of each named executive officer’s overall compensation opportunity.
	We Balance Short-Term and Long-Term Incentives: We use multiple performance measures in awarding cash bonuses and granting annual equity awards, which mitigates compensation-related risk; we also measure performance across various performance periods.
	We Maintain Stock Ownership Guidelines: We have robust stock ownership guidelines for our named executive officers and directors.
	We Retain an Independent Compensation Consultant: Our Compensation Committee engages an independent consultant to provide guidance on a variety of compensation matters.

What We Don't Do:
	No Automatic Salary Increases or Guaranteed Bonuses: We do not guarantee annual salary increases or bonuses and none of the employment agreements with our named executive officers contain such provisions.
	We Do Not Allow Uncapped Payouts: We have a defined compensation system that does not allow for uncapped bonus payouts.
	We Do Not Have Tax Gross-Ups: We do not provide tax gross-ups on any severance, change-in-control or other payments.
	We Do Not Allow Hedging: We do not permit executives officers or directors to hedge our securities.
	We Do Not Provide Excessive Perquisites: Our named executive officers receive limited perquisites and benefits.

Our 2016 long-term incentive program aimed to more closely align the interests between our senior management, including our named executive officers, and our stockholders. Additional details of our long-term equity incentive program for 2016 is set forth below:

Feature	2016 Long-term equity incentive plan
Award Composition:	Performance-based(1)
Performance Period:	Three years
Performance Criteria:	Total stockholder return over the performance period measured relative to the MSCI US REIT Index (RMS)
Vesting based on satisfaction of performance condition:	Less than threshold:	0%
	At threshold:	25%
	At target:	50%
	At maximum:	100%
Time vesting of equity awards that performance vest:	50% following the end of the three-year performance period and 50% in the following year

(1) Certain named executive officers received one-time time-based awards in February 2016 in addition to annual performance-based awards. See “Description of Individual Elements of Compensation– 2016 One-Time Transaction Equity Award” below.

Our long-term incentive plan is illustrated below:

Pay for Performance

Pay for performance is an important component of our compensation philosophy. Consistent with this focus, our compensation program includes annual incentive bonuses and long-term equity incentive compensation.

Under our annual incentive bonus program, we measure each named executive officer’s performance based on financial, leasing, profitability and individual goals. In 2016, the financial goals consisted of core funds from operations (“core FFO”) targets, the leasing goals included speculative incremental revenue and annual GAAP signings targets, and the profitability goals were focused on Adjusted EBITDA margin targets. Individual goals were categorized around the following areas: customer focus, growth/product, go to market strategy, profitability and operational excellence and organizational excellence.

We also provide long-term equity incentive awards that are subject to both time-based and performance-based vesting conditions. For performance-based long-term equity incentive awards granted in 2016, the performance-based vesting condition was based on our total stockholder return during the three-year performance period commencing in January 2016, relative to the total stockholder return of the MSCI US REIT Index (RMS) during the applicable performance period. In 2016, the Company’s total return to stockholders was over 34%, and outperformed the RMS by over 26%:

During the past several years, the Company has been focused on growing our operations internally and through strategic acquisitions as well as through improved leasing, asset management and marketing activities, improving our balance sheet, strategically accessing the capital markets and focusing on our organizational development. More recently, the Company has focused on its product strategy, investing in strategic initiatives to complement its existing portfolio in order to attract a wider base of customers, and organizational structuring to support these new strategies and initiatives as well as the continued growth of the Company. Accomplishments in the year ended December 31, 2016 include, among other things, the following:

2016 Advisory Vote on the Compensation of Named Executive Officers

In May 2016, we provided stockholders a non-binding, advisory vote to approve the compensation of our named executive officers (the 2016 say-on-pay vote). At our 2016 Annual Meeting of Stockholders, our stockholders overwhelmingly approved the compensation of our named executive officers, with approximately 95% of the votes cast in favor of the 2016 say-on-pay vote. In evaluating our executive compensation program, the Compensation Committee considered the results of the 2016 say-on-pay vote and numerous other factors as discussed in this Compensation Discussion and Analysis. The Compensation Committee will continue to monitor and assess our executive compensation program and consider the outcome of our say-on-pay votes when making future compensation decisions for our named executive officers.

 

Stockholder Interest Alignment

We believe that our equity award program further enhances long-term stockholder value and encourages long-term performance by providing a strong alignment of interests between our named executive officers and our stockholders. Therefore, equity is a key component of our executive compensation program, with equity awards ranging between 52% and 71% of our named executive officers’ compensation opportunity in 2016. All equity awards granted to our named executive officers in 2016 were in the form of long-term incentive units. These awards put significant value at risk for our named executive officers and are effective as an ownership and retention tool.

Good Governance

In furtherance of our objective of implementing policies and practices that are mindful of the concerns of our stockholders, we have separated the roles of Chief Executive Officer (currently Mr. Stein) and Chairman of the Board (currently Mr. Singleton). Additionally, the Compensation Committee retained FPL, an independent compensation consultant, to assist the Compensation Committee, among other things, in conducting and presenting the annual review of the total compensation packages for our executive officers. FPL was initially selected as the Compensation Committee’s compensation consultant in 2013 in part for its extensive experience in the REIT industry. The Compensation Committee assessed the independence of FPL pursuant to the rules prescribed by the SEC and the NYSE and concluded that no conflict of interest existed in 2016 that would prevent FPL from serving as an independent consultant to the Compensation Committee. In addition, the Compensation Committee considered the independence of outside legal counsel that provides advice to the Compensation Committee, consistent with the rules prescribed by the SEC and the NYSE, and determined that such adviser is independent.

The Compensation Committee consistently reviews our executive compensation program to ensure that it provides competitive pay opportunities. Our compensation programs consist of elements designed to complement each other and reward achievement of short-term and long-term objectives tied to our performance through association with multiple performance metrics. We have chosen the selected metrics to align employee compensation, including compensation for the named executive officers, to our business strategy. The following are a few key 2016 actions and decisions with respect to our compensation program:

• As in past years, the named executive officers were eligible to earn cash incentive compensation based upon achievement of specific financial, operational and organizational objectives for 2016, as approved by the Compensation Committee, that are designed to challenge the named executive officers to high performance.

• A significant portion of our named executive officers’ total cash compensation remains dependent on Company, business unit and individual performance.

• The Compensation Committee determines annual base salaries after reviewing salary survey data of, and the Company’s historical performance relative to, its peer group.

• Our compensation programs encourage employees to build and maintain an ownership interest in the Company. In addition to performance-based vesting, 2016 equity awards granted to our named executive officers are subject to time-based vesting following the end of the applicable three-year performance period.

• In 2016, FPL was retained directly by and reported to the Compensation Committee.  FPL did not have any prior relationship with any of our named executive officers.

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    32

• Base salaries represented 11% to 28% and performance-based equity compensation represented 45% to 65% of the total compensation opportunity for our named executive officers reflecting our philosophy of paying for performance and aligning the interests of our named executive officers with stockholders’ interests.

• Based on the recommendations of management, a review of the Company’s business plan and strategic objectives and the analysis provided by FPL, the Compensation Committee established financial, leasing, profitability and individual goals for each named executive officer for 2016.

Overview of Our Executive Compensation Program

Objectives of Our Executive Compensation Program

The Compensation Committee is responsible for establishing, modifying and approving the compensation program for our executive officers. The objective of our executive compensation program is to attract, retain and motivate experienced and talented executives who can help maximize stockholder value. We believe that a significant portion of the compensation paid to executive officers should be closely aligned with our performance on both a short-term and long-term basis. In order to achieve this objective, in addition to annual base salaries, our executive compensation program uses a combination of annual cash bonus incentives and long-term incentives through equity-based compensation. We use equity-based awards as long-term incentives because ownership of equity in the Company aligns the interests of the executives with long-term creation of stockholder value and we view our company-wide performance and growth as the relevant long-term metric for our equity-based awards, while our annual cash awards are targeted to reward the attainment of narrower, short-term performance objectives. The program is intended to encourage high performance, promote accountability and ensure that the interests of the executives are aligned with the interests of our stockholders by linking a significant portion of executive compensation directly to achievement of corporate goals and increases in stockholder value. We seek to provide total compensation to our executive officers that is competitive with the total compensation paid by comparable REITs and other real estate companies in our peer group, as discussed in more detail below.

The following are our principal objectives in establishing compensation for executive officers:

• Attract and retain individuals with superior ability, managerial talent and leadership capability;

• Ensure that executive officer compensation is aligned with our corporate strategies, business objectives and the long-term interests of our stockholders;

• Incentivize management to achieve key strategic and financial performance measures by linking incentive award opportunities to the achievement of performance goals in these areas; and

• Enhance the executive officers’ incentive to increase our stock price and maximize stockholder value, as well as promote retention of key executives, by providing a portion of total compensation opportunities for senior management in the form of direct ownership in our Company through equity awards, including awards of long-term incentive units in our Operating Partnership which are redeemable for shares of our Common Stock.

Elements of Compensation

The major elements of compensation for our named executive officers are (1) a base salary, intended to provide a stable annual income for each executive officer at a level consistent with such officer’s individual contributions to the Company, (2) annual cash performance bonuses, intended to link each executive officer’s compensation to the Company’s performance and to such officer’s individual performance, and (3) long-term compensation, which includes grants of long-term incentive units in our Operating Partnership, intended to encourage actions to maximize stockholder value. Each of these elements is discussed in more detail below.

The following charts illustrate the allocation of the major elements of compensation for our named executive officers for 2016:

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    33

The percentages reflect the amounts of 2016 base salary and target annual cash bonus and the aggregate grant date fair values of long-term incentive units granted in 2016.

Our named executive officers are also entitled to full vesting of all equity awards (other than certain performance-based vesting equity awards that have not met their performance-based vesting requirement) upon a change in control of the Company and to severance payments and benefits upon certain qualifying terminations of employment (including in connection with a change in control). We provide these benefits to our named executive officers in order to give them the personal security and stability necessary for them to focus on the performance of their duties and responsibilities to us and to encourage retention through a potential change in control. These items are described below under “Executive Compensation — Potential Payments upon Termination or Change in Control.”

We believe that each of these elements plays an important role in our overall executive compensation program and together serve to achieve our compensation objectives. The Compensation Committee allocates total compensation between the cash and equity components based on a review of the practices of our peer group and the performance of the executive officer and the Company, while considering the balance among providing stability, short-term incentives and long-term incentives to align the interests of management with our stockholders. For 2016, the percentage of salary and annual cash bonus paid relative to total compensation ranged from 33% to 51% for our named executive officers (excluding Mr. Miszewski, who received compensation only for the portion of 2016 during which he was employed by us).

Determination of Compensation Awards

The Compensation Committee annually reviews and determines the total compensation to be paid to our named executive officers. Our management, after reviewing competitive market data and advice from a compensation consultant engaged by the Compensation Committee, makes recommendations regarding the compensation packages for our executive officers. The Compensation Committee in its review of these recommendations and in establishing the total compensation for each of our named executive officers considers several factors, including each executive officer’s roles and responsibilities, each executive officer’s performance, any significant accomplishments of the executive officer, our Company’s financial and operational targets and performance, and competitive market data applicable to each executive officer’s position and functional responsibilities.

Competitive Market Data and Compensation Consultant

In November 2015 and February 2016, the Compensation Committee reviewed the salary, bonus and equity compensation paid to our named executive officers. In conducting this review, the Compensation Committee retained the services of FPL as the Compensation Committee’s independent compensation consultant.

For its consulting services, FPL was instructed to review the Company’s existing compensation program, provide current data with regard to industry trends, provide information regarding long-term compensation plans, identify and provide commentary on a peer group and provide cash and equity incentive award information for the peer group and assess and review the long-term incentive program.

Peer Group Review

The Compensation Committee reviews total cash and long-term compensation levels against those of our peer group companies in order to ensure executive compensation is set at levels that will attract and motivate qualified executives while rewarding performance based on corporate objectives. The Compensation Committee determines annual base salaries after reviewing salary survey and other publicly available data of, and the Company’s historical performance relative to, its peer group. The Compensation Committee sets compensation levels for each executive officer on the basis of several factors, including the executive officer’s level of experience, tenure with the Company, competitive market data applicable to the executive officer’s position and functional responsibilities, promoting retention, the performance of the executive officer and our Company’s annual and long-term performance.

In developing a peer group for the Company, the Compensation Committee considers the following key elements:

• Our core operations are focused on data centers and real estate, limiting the number of our direct competitors;

• Our operations are global, with data centers located in twelve countries across four continents; and

• We operate and are classified as a REIT and are one of the very few global technology-based REITs.

Our Compensation Committee utilized company size (using total market capitalization ranging between 0.5x and 2.0x that of the Company), scope and breadth of operations, as well as level of operational focus to determine which companies could reasonably be used to assess competitive pay. Although the REITs in our peer group were among the closest in comparison to us based on these factors, the combination of the size and global nature of our operations and our significant operational focus put us in a unique category. Generally, such companies individually demonstrated relevance in one or two of these categories, but not in all of these categories.

The peer group used to review 2016 base salaries, bonus targets and long-term equity awards consisted of the following eighteen companies, which were selected as our peer group companies in November 2015 by our Compensation Committee, with advice from FPL:

Alexandria Real Estate Equities, Inc	Equinix, Inc.	Prologis, Inc.
AvalonBay Communities, Inc.	Equity Residential	SL Green Realty Corp.
Boston Properties, Inc.	Federal Realty Investment Trust	Ventas, Inc.
Brixmor Property Group Inc.	HCP, Inc.	Vornado Realty Trust
Douglas Emmett, Inc.	Kimco Realty Corporation	W.P. Carey Inc.
Duke Realty Corporation	Macerich Company

In August 2016, the Compensation Committee and management, with advice from FPL, reviewed our peer group taking into consideration our addition to the S&P 500 Index in May 2016. As a result of the Company being amongst the largest publicly traded REITs, the following modifications, as recommended by FPL, were made to the above peer group:

The companies added to our peer group are members of the S&P 500 Index while the companies removed from our peer group are not part of the S&P 500 Index.

After taking into account the above changes, our current peer group consists of the following seventeen companies.

• DuPont Fabros Technology, Inc.

• Equinix, Inc.

• QTS Realty Trust, Inc.

Annual Performance Reviews

To aid the Compensation Committee in setting base salaries, cash incentive targets and long-term equity awards, management provides recommendations annually to the Compensation Committee regarding the compensation of all named executive officers. The Compensation Committee, with input from the Board, annually reviews the performance of our Chief Executive Officer, and our Chief Executive Officer reviews the performance of the remaining named executive officers. All of these reviews are presented to the Compensation Committee to provide input about their contributions to our success for the period being assessed.

Description of Individual Elements of Compensation

During the year ended December 31, 2016, compensation for our named executive officers was composed of base salary, annual performance-based cash bonuses and equity compensation awards. The Compensation Committee approved the following compensation for each of our named executive officers for 2016 (except for Mr. Mills, who was not a named executive officer in 2015), which consists of base salary, annual cash incentive bonus and the grant date fair value of long-term incentive units:

Named Executive Officer	2016 Total Compensation		2015 Total Compensation
A. William Stein	$	8,148,670	$	5,249,989
Andrew P. Power		2,712,509		3,200,989
Jarrett B. Appleby		2,313,307		2,757,857
Scott E. Peterson		2,988,741		2,734,678
Matthew J. Miszewski		1,487,729		1,783,871

Mr. Mills’ 2016 total compensation, consisting of base salary, annual cash incentive bonus and the grant date fair value of long-term incentive units, was $1,626,767.

The 2016 total compensation for each of Messrs. Power and Appleby is lower than their respective 2015 total compensation due to one-time equity grants of long-term incentive units in our Operating Partnership awarded to them in 2015 in connection with the commencement of their employment with us in 2015. Mr. Miszewski received lower compensation during 2016 because he left the Company in August 2016 and did not receive a full year of compensation.

Annual Base Salary

We provide our named executive officers and other employees with base salaries to compensate them for services rendered each year. Base salaries comprise the stable part of the compensation program and are reviewed on an annual basis to remain competitive with our peers. This compensation element is necessary to provide the financial certainty that our executives seek when they are considering whether to join or remain with our Company. The base salaries for each of the named executive officers for 2016 were determined based in part on the analysis by FPL of the compensation practices of companies in our peer group. The Compensation Committee also considered the Company’s historical performance relative to its peer group as well as the performance of each of our named executive officers and their contributions to our overall success. Based on its review, the Compensation Committee increased the salaries of each of our named executive officers. The 2016 salaries for all of our named executive officers are set forth below under the heading “Executive Compensation —Summary Compensation Table.” The following table sets forth the 2016 annual base salary rates and the 2015 annual base salary rates for each named executive officer (excluding Mr. Mills, who was not a named executive officer in 2015). Mr. Mills’ 2016 base salary was $425,028.

Named Executive Officer	2016 Salary		2015 Salary
A. William Stein	$	880,000	$	750,000
Andrew P. Power		500,000		425,000
Jarrett B. Appleby		450,000		425,000
Scott E. Peterson		550,171		525,171
Matthew J. Miszewski		385,000		350,000

Annual Incentive Compensation

Our annual incentive bonus program is structured to reward named executive officers based on our performance and the individual executive officer’s contribution to that performance. Annual incentive bonuses are paid in cash in the following year if and to the extent performance objectives established by the Compensation Committee at the beginning of the applicable year are achieved. The Compensation Committee believes that the payment of the annual incentive bonus in cash provides the incentive necessary to retain executive officers and reward them for short-term Company performance.

Each named executive officer’s annual incentive bonus opportunity for 2016 was established by our Compensation Committee and is described in the “Executive Compensation —Grants of Plan-Based Awards” table. Each named executive officer’s bonus opportunity provides for target and maximum bonus amounts, expressed as a percentage of base salary. In setting these amounts, our Compensation Committee considers, among other factors, each executive officer’s roles and responsibilities within our Company, the total compensation package associated with that position and competitive market data applicable to that position.

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    36

For 2016, the threshold, target and maximum bonus amounts, expressed as a percentage of annual base salary, were as follows:

Named Executive Officer	Threshold			Target			Maximum
A. William Stein		75	%		150	%		225	%
Andrew P. Power		50	%		100	%		150	%
Jarrett B. Appleby		50	%		100	%		150	%
Scott E. Peterson		50	%		100	%		150	%
Joshua A. Mills		40	%		75	%		115	%
Matthew J. Miszewski		50	%		100	%		150	%

The threshold, target and maximum bonus payout percentages for each of the named executive officers, and the differences in such percentages among the named executive officers, were also determined by reference to competitive market data and practices as well as consideration of each named executive officer’s performance, role and responsibilities at our Company.

For 2016, based on the recommendations of management and a review of the Company’s business plan, the Compensation Committee established financial, leasing, profitability and individual goals for each named executive officer. The financial goals consisted of core FFO targets, the leasing goals included speculative incremental revenue and annual GAAP signings targets, and the profitability goals were focused on Adjusted EBITDA margin targets. Individual goals were categorized around the following areas: customer focus, growth/product, go to market strategy, profitability and operational excellence, and organizational excellence.

An overview of the structure of the annual incentive bonuses for the CEO and the other named executive officers is provided below:

 

FFO is used by industry analysts and investors as a supplemental performance measure of a real estate investment trust, or REIT. FFO represents net income (loss) available to common stockholders (computed in accordance with U.S. GAAP), excluding gains (or losses) from sales of property, impairment charges, real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. In excluding real estate related depreciation and amortization and gains and losses from property dispositions, FFO provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. For purposes of determining 2016 cash bonuses, the Compensation Committee determined it was appropriate to use 2016 core FFO per diluted share and unit, which is FFO adjusted to exclude certain items that do not represent core revenue streams or expenses. The Compensation Committee determined that in 2016 core FFO was more indicative of the Company’s performance and gave a more accurate picture of the Company’s annual performance. Core FFO for the year ended December 31, 2016 excluded approximately $33.2 million of termination fees and other non-core revenues, and included approximately $20.5 million of transaction and integration expenses, $1 million in loss from early extinguishment of debt, $10.3 million in issuance costs associated with redeemed preferred stock, $6.3 million in severance, equity acceleration and legal expenses, $3 million in loss on currency forwards, and $0.2 million of other non-core expense adjustments.

For purposes of our 2016 annual cash bonus program, the minimum, target and maximum levels of 2016 core FFO established by the Compensation Committee were $5.45, $5.53 and $5.60 per diluted share and unit, respectively. The minimum, target and maximum amounts were set by the Compensation Committee based on a number of factors, including expectations surrounding acquisitions and leasing assumptions, financing assumptions, earnings growth, general economic conditions, real estate and technology fundamentals and other specific circumstances facing the Company. For the purpose of determining bonuses, the Compensation Committee determined it was appropriate to use core FFO achieved by the Company and exclude certain profits, losses or expenses to give a more accurate picture of the Company’s annual performance. The core FFO achieved by the Company in 2016 was $5.72 per diluted share and unit, which exceeded the maximum core FFO level.

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    37

The leasing goals for 2016 were comprised of speculative incremental revenue and annual GAAP signings metrics. The Company achieved leasing goals below the minimum level in 2016. The profitability objective was measured by specific increases to the Adjusted EBITDA margin. The minimum, target and maximum levels of Adjusted EBITDA margin were 55.3%, 56.3% and 57.3%, respectively. The Adjusted EBITDA margin achieved by the Company in 2016 was 57.3%, which was at the maximum level.

The weightings of the specific financial, leasing, profitability and individual goals for each named executive officer were established by the Compensation Committee based on the named executive officer’s areas of responsibility, as follows:

Named Executive Officer	Core FFO Per Share	Leasing	Profitability	Individual Goals
A. William Stein	55%	10%	10%	25%
Andrew P. Power	40%	10%	10%	40%
Jarrett B. Appleby	40%	10%	10%	40%
Scott E. Peterson	40%	10%	10%	40%
Joshua A. Mills	40%	10%	10%	40%
Matthew J. Miszewski	40%	10%	10%	40%

Individual goals for our named executive officers included performance objectives related to: expanding our partnerships and alliances; growth through strategic acquisitions and organic growth; evolving existing products and launching new products; improving processes related to our customer relationships; financial and operating metrics; and talent retention, cross-functional effectiveness and workforce integration.

The Compensation Committee, based in part on the recommendations of management, determined each named executive officer’s bonus based on the achievement of the established goals. For 2016, the Compensation Committee determined that the Company had met or exceeded each of the 2016 core FFO and 2016 Adjusted EBITDA margin maximum levels established by the Compensation Committee and determined that with respect to the leasing goals, management had achieved certain objectives below minimum in 2016. Consistent with our pay-for-performance philosophy, 2016 bonus payouts did not include amounts related to the 10% allocated to leasing goals due to the achievement of the leasing goals below the minimum level. Also consistent with our compensation philosophy to pay for performance, because the maximum levels of our 2016 core FFO goal and 2016 Adjusted EBITDA margin goals were achieved, and because the core FFO goal is weighted the heaviest, the 2016 performance-based annual incentive cash bonuses for our named executive officers represented 127% to 135% of their respective target bonuses. The following table sets forth the 2016 bonus paid, the 2016 bonus paid as a percentage of the base salary rate for each named executive officer, the 2016 bonus paid as a percentage of the target bonus amount for each named executive officer and the 2016 bonus paid as a percentage of the 2015 bonus paid to each named executive officer (other than Mr. Miszewski, who departed the Company in August 2016 and, accordingly, did not receive a 2016 bonus):

Named Executive Officer	2016 Bonus	Percentage of Eligible 2016 Base Salary	Percentage of 2016 Target Bonus	Percentage of 2015 Bonus
A. William Stein	$ 1,782,000	203%	135%	119%
Andrew P. Power	675,000	135%	135%	109%
Jarrett B. Appleby	517,500	115%	115%	115%
Scott E. Peterson	742,731	135%	135%	103%
Joshua A. Mills	405,902	96%	127%	108%

Equity Incentive Compensation

We have historically granted to our executive officers long-term incentive units in our Operating Partnership under our 2014 Plan. We believe that a significant portion of the compensation paid to executive officers should be closely aligned with our performance on both a short-term and long-term basis. The Compensation Committee believes that, while our annual bonus program provides awards for positive short-term performance, equity participation creates a vital long-term partnership between executive officers and stockholders. The program is intended to encourage high performance, promote accountability and ensure that the interests of the executive officers are aligned with the interests of our stockholders by linking a significant portion of executive compensation directly to increases in stockholder value.

The Compensation Committee allocates annual incentive compensation between the cash components and equity

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    38

compensation based on a review of the practices of our peer group and competitive market data, while considering the balance among providing short-term incentives and long-term incentives to align the interests of management with our stockholders. The Compensation Committee did not utilize a formulaic approach in allocating the cash and equity-based portions of incentive compensation.

2016 Long-Term Incentive Units

The Compensation Committee believes that long-term incentive units are an effective incentive to retain our executive officers and increase their performance and closely align the interests of our executive officers with the long-term interests of our stockholders. Long-term incentive units may be issued to eligible participants for the performance of services to or for the benefit of our Operating Partnership. Long-term incentive units (other than Class C Units and Class D Units that are not performance vested Class D Units in our Operating Partnership), whether vested or not, receive the same quarterly per-unit distributions as common units in our Operating Partnership, which equal the per-share distributions on our Common Stock. Class D Units that are not performance vested Class D Units generally receive quarterly per-unit distributions equal to ten percent of the distributions made with respect to an equivalent number of common units in our Operating Partnership.

Initially, long-term incentive units do not have full parity with common units with respect to liquidating distributions. If such parity is reached, vested long-term incentive units may be converted into an equal number of common units of our Operating Partnership at any time, and thereafter enjoy all the rights of common units of our Operating Partnership, including redemption rights.

In order to achieve full parity with common units, long-term incentive units must be fully vested and the holder’s capital account balance in respect of such long-term incentive units must be equal to the capital account balance of a holder of an equivalent number of common units. The capital account balance attributable to each common unit is generally expected to be the same, in part because of the amount credited to a partner’s capital account upon their contribution of property to the Operating Partnership, and in part because the partnership agreement provides, in most cases, that allocations of income, gain, loss and deduction (which will adjust the partners’ capital accounts) are to be made to the common units on a proportionate basis. As a result, with respect to a number of long-term incentive units, it is possible to determine the capital account balance of an equivalent number of common units by multiplying the number of long-term incentive units by the capital account balance with respect to a common unit.

A partner’s initial capital account balance is equal to the amount the partner paid (or contributed to the Operating Partnership) for its units and is subject to subsequent adjustments, including with respect to the partner’s share of income, gain or loss of the Operating Partnership. Because a holder of long-term incentive units generally will not pay for the long-term incentive units, the initial capital account balance attributable to such long-term incentive units will be zero. However, the Operating Partnership is required to allocate income, gain, loss and deduction to the partners’ capital accounts in accordance with the terms of the partnership agreement, subject to applicable Treasury Regulations. The partnership agreement provides that holders of long-term incentive units will receive special allocations of gain in the event of a sale or “hypothetical sale” of assets of our Operating Partnership prior to the allocation of gain to the Company or other limited partners with respect to their common units. The amount of such allocation will, to the extent of any such gain, be equal to the difference between the capital account balance of a holder of long-term incentive units attributable to such units and the capital account balance attributable to an equivalent number of common units. If and when such gain allocation is fully made, a holder of long-term incentive units will have achieved full parity with holders of common units. To the extent that, upon an actual sale or a “hypothetical sale” of the Operating Partnership’s assets as described above, there is not sufficient gain to allocate to a holder’s capital account with respect to long-term incentive units, or if such sale or “hypothetical sale” does not occur, such units will not achieve parity with common units.

The term “hypothetical sale” refers to circumstances that are not actual sales of the Operating Partnership’s assets but that require certain adjustments to the value of the Operating Partnership’s assets and the partners’ capital account balances. Specifically, the partnership agreement provides that, from time to time, in accordance with applicable Treasury Regulations, the Operating Partnership will adjust the value of its assets to equal their respective fair market values, and adjust the partners’ capital accounts, in accordance with the terms of the partnership agreement, as if the Operating Partnership sold its assets for an amount equal to their value. Times for making such adjustments generally include the liquidation of the Operating Partnership, the acquisition of an additional interest in the Operating Partnership by a new or existing partner in exchange for more than a de minimis capital contribution, the distribution by the Operating Partnership to a partner of more than a de minimis amount of partnership property as consideration for an interest in the Operating Partnership, in connection with the grant of an interest in the Operating Partnership (other than a de minimis interest) as consideration for the performance of services to or for the benefit of the Operating Partnership (including the grant of a long-term incentive unit), the issuance of a non-compensatory option to acquire an interest in the Operating Partnership, the acquisition of an interest in the Operating Partnership upon the exercise of a non-compensatory option to acquire such an interest, and at such other times as may be desirable or required to comply with the Treasury Regulations.

The Compensation Committee approves awards of long-term incentive units on the basis of several factors, including the executive officer’s total compensation package, the executive officer’s roles and responsibilities within our Company, the executive officer’s performance, any significant accomplishments of the executive officer, our Company’s financial and operating performance and competitive market data applicable to each executive officer’s position and functional responsibilities.

2016 Annual Equity Awards

In 2016, the Compensation Committee granted awards of performance-based Class D Units in our Operating Partnership to each of our named executive officers. Our named executive officers’ 2016 equity awards are set forth below in the “Executive Compensation — Grants of Plan-Based Awards” table.

The Class D Units awarded in 2016 are subject to performance-based vesting on a multi-year performance period, subject to the executive officer’s continued service. Based on the recommendations of management and FPL and a review of the Company’s business plan, the performance condition of the Class D Units is based on our total stockholder return over a period of three years commencing in January 2016 or, if earlier, ending on the date on which a change in control of the Company occurs (the “Performance Period”), measured relative to the MSCI US REIT Index (RMS) over the performance period (the “Performance Condition”).

A portion of each award of Class D Units is designated as a number of “base units” with respect to which performance vesting is measured based on the difference between the Company’s total stockholder return (TSR) percentage and the TSR percentage of the MSCI US REIT Index (the “MSCI Index Relative Performance”). In the event that the MSCI Index Relative Performance during the Performance Period is achieved at the “threshold,” “target” or “high” level as set forth below, the award will become performance-vested with respect to the percentage of base units set forth below:

		Threshold	Target	High
MSCI Index Relative Performance	< -300 bps	-300 bps	+ 100 bps	+ 500 bps
Performance Vesting Percentage	0%	25%	50%	100%

In the event that the MSCI Index Relative Performance is achieved at less than the “threshold” level, none of the base units will vest.

If the MSCI Index Relative Performance falls between the levels specified above, the percentage of base units that will performance vest will be determined using straight-line linear interpolation between such levels.

An additional number of Class D Units subject to the award (the “distribution equivalent units”) having a value equal to the dividends declared during the Performance Period in respect of the shares of our Common Stock corresponding to the base units that become performance vested (less any actual distributions made with respect to such units) will vest in full as of the completion of the Performance Period. For purposes of calculating the number of distribution equivalent units, the dividend amount will be adjusted (plus or minus) to reflect the gain or loss on such amount had the dividends been reinvested in shares of our Common Stock on the applicable payment date.

Following the completion of the Performance Period, the plan administrator will determine the number of base units that have become performance-vested and the number of distribution equivalent units. The number of Class D Units that constitute distribution equivalent units plus the number of performance-vested base units are collectively referred to as the “Performance Vested Units.

”Following the completion of the Performance Period, the performance-vested base units are subject to the award’s time vesting condition and become fully vested as follows, subject to the executive’s continued service through each applicable vesting date: 50% on February 27, 2019 and 50% on February 27, 2020. Distribution equivalent units will vest in full as of the completion of the Performance Period and will not be subject to additional time vesting requirements.

In the event of a change in control of the Company, all outstanding Performance Vested Units (including any Class D Units that become Performance Vested Units in connection with the change in control) will vest in full as of the date of the change in control, subject to the executive officer’s continued service until immediately prior to the change in control.

Except as otherwise described below, any Class D Units that have not fully vested as of the date on which an executive officer’s service terminates for any reason will be cancelled and forfeited by the executive officer.

If an executive officer’s service terminates due to death or disability prior to the completion of the Performance Period, the Class D Units will remain outstanding and eligible to become Performance Vested Units in accordance with the performance vesting schedule described above, and any Class D Units that become Performance Vested Units will be fully vested as of the completion of the Performance Period. Any Class D Units that do not become fully vested will be cancelled and forfeited upon the completion of the Performance Period.

If an executive officer’s service is terminated by the Company or an affiliate thereof other than for cause, by the executive officer for good reason, or due to the executive officer’s retirement (each such term as defined in the applicable

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    40

award agreement), in any case, prior to the completion of the Performance Period, the Class D Units will remain outstanding and eligible to become Performance Vested Units in accordance with the performance vesting schedule described above, and the number of such units that vest in full upon the completion of the Performance Period will be determined on a pro rata basis, based on the number of days that the executive officer was employed during the Performance Period. Any Class D Units that do not become fully vested will be cancelled and forfeited upon the completion of the Performance Period.

If an executive officer’s service is terminated due to the executive officer’s death or disability, by the Company or an affiliate thereof other than for cause, by the executive officer for good reason or due to the executive officer’s retirement, in any case, following the completion of the Performance Period, any Performance Vested Units that remain subject to time-based vesting will vest in full upon such termination.

2016 One-Time Transaction Equity Award

In February 2016, in recognition of the successful closing of the acquisition of Telx Holdings, Inc. (the “Telx Acquisition”) in October 2015, the Compensation Committee approved awards of time-based long-term incentive units to Messrs. Stein, Power, Peterson and Mills in lieu of additional 2015 cash bonuses. The time-based long-term incentive units vest in installments of 25% per year over a four-year period, subject to the applicable executive officer’s continued service through the applicable vesting date. From the closing of the Telx Acquisition to December 31, 2016, the Company delivered a total stockholder return of over 47%.

If an executive officer’s service terminates due to death or disability, the long-term incentive units will vest in full upon such termination. Upon an executive officer’s termination of service for any other reason, any then-unvested long-term incentive units will automatically be cancelled and forfeited by the executive.

The number of units subject to the time-based long-term incentive unit awards is set forth below:

Named Executive Officer	Units (#)
A. William Stein	6,219
Andrew P. Power	2,488
Scott E. Peterson	2,488
Joshua A. Mills	1,244

Severance and Change in Control Benefits — Employment Agreements

We have entered into employment agreements with our named executive officers to help provide stability and security and encourage them to remain with us. These employment agreements include severance and change in control benefits, among other things. The terms of these severance and change in control arrangements are described below in more detail under the caption “Executive Compensation — Potential Payments upon Termination or Change in Control.” We provide these benefits to our named executive officers in order to give them the personal security and stability necessary for them to focus on the performance of their duties and responsibilities to us and to encourage retention through a potential change in control.

Perquisites

We generally provide our named executive officers with perquisites and other personal benefits that apply uniformly to all of our employees. The Compensation Committee periodically reviews the levels of perquisites and other personal benefits provided to named executive officers. In 2016, we provided the named executive officers with basic life insurance, medical, dental, vision and disability insurance benefits, for which our named executive officers were charged the same rates as all other employees, 401(k) matching funds, health savings account employer contributions and parking, as applicable. Other than these standard benefits, we do not provide any other perquisites.

Tax and Accounting Considerations

Internal Revenue Code Section 162(m)

When reviewing compensation matters, the Compensation Committee considers the anticipated tax consequences to us (and, when relevant, to our executive officers) of the various payments under our compensation programs. Section 162(m) of the Code disallows a tax deduction for any publicly held corporation for individual compensation of more than $1.0 million in any taxable year to certain executive officers other than compensation that is performance-based under a plan that is approved by the stockholders and that meets certain other technical requirements. We believe that we qualify as a REIT under the Code and generally are not subject to federal income taxes, provided that we distribute to our stockholders at least 100% of our taxable income each year. As a result, we do not expect that the payment of compensation that does not satisfy the requirements of Section 162(m) of the Code will have a material adverse federal income tax consequence to us, provided we continue to distribute at least 100% of our taxable income each year. Consequently, the Compensation Committee does not necessarily limit executive compensation to the amount deductible under Section 162(m) of the Code. In appropriate circumstances, the Compensation Committee may implement programs that recognize a full range of performance criteria important to our success and to ensure that our executive officers are compensated in a manner consistent with our best interests and those of our stockholders, even where the compensation paid under such programs may not be deductible under Section 162(m) of the Code.

ASC Topic 718

Accounting Standards Codification Topic 718, Compensation — Stock Compensation (“ASC Topic 718”) requires us to recognize an expense for the fair value of equity-based compensation awards. Grants of stock-based compensation are accounted for under ASC Topic 718. The Compensation Committee regularly considers the accounting implications of significant compensation decisions, especially in connection with decisions that relate to equity compensation awards. As accounting standards change, we may revise certain programs to appropriately align the cost of our equity awards with our overall executive compensation philosophy and objectives.

Narrative Disclosure to Compensation Tables

Employment Agreements

A. William Stein

On November 23, 2014, in connection with Mr. Stein’s appointment as our Chief Executive Officer, we entered into an amended and restated employment agreement with Mr. Stein, our Chief Executive Officer and then-Chief Financial Officer, which replaced and superseded his prior employment agreement with us. The terms of the amended and restated employment agreement are described below.

The employment agreement has an initial three-year term which continues through November 23, 2017, and will automatically be extended for one additional year upon the expiration of the initial term unless either party provides notice of such party’s intention not to renew the employment agreement not less than 60 days prior to the expiration of the initial term.

Pursuant to the employment agreement, Mr. Stein’s initial annual base salary was $750,000, and is subject to increase, but not decrease, in the discretion of the Compensation Committee. Mr. Stein’s annual base salary as of March 1, 2017 is $1,000,000. Mr. Stein is also eligible to earn an annual cash performance bonus under the Company’s incentive bonus plan based on the satisfaction of performance criteria established in accordance with the terms of such plan. The employment agreement provides that Mr. Stein’s target and maximum annual bonuses will be at least 100% and 150%, respectively, of his base salary. Mr. Stein’s current target and maximum annual bonus levels are 150% and 225%, respectively, of his base salary. Mr. Stein is eligible to participate in all incentive, savings and retirement plans, practices, policies and programs, and medical and other group welfare plan coverage and fringe benefits provided to similarly-situated executive officers.

Mr. Stein’s employment agreement provides that if his employment is terminated by us without “cause” or by Mr. Stein for “good reason” (each as defined in the employment agreement), then, subject to his execution and non-revocation of a general release of claims and his continued compliance with applicable restrictive covenants, he will become eligible for a lump-sum severance payment within 30 days after the date of such termination in an amount equal to the sum of (i) two times the sum of (a) his then-current annual base salary plus (b) the average annual bonus earned by Mr. Stein during the three fiscal years preceding the year of termination (the “average bonus”), (ii) a prorated portion of his target annual bonus for the partial fiscal year in which the termination date occurs (the “stub year bonus”) and (iii) if the termination occurs after a fiscal year-end but before annual bonuses are paid or determined for such preceding fiscal year, an amount equal to such unpaid bonus (if any), if determined, or the target bonus if bonuses have not yet been determined (in either case, the “prior year bonus”), if any. Mr. Stein will also become eligible for continued health insurance coverage at least equal to the coverage that would have been provided to him if his employment had not been terminated, for a period ending on the earlier of the eighteen-month anniversary of such termination or the date on which he becomes eligible to receive comparable health insurance under a subsequent employer’s plan, as well as Company-paid outplacement services for twelve months following his termination. In addition, all outstanding equity-based awards held by Mr. Stein that are subject to vesting based on continued employment or the lapse of time will become fully vested and exercisable.

As used in the employment agreements of our named executive officers, “good reason” shall generally mean the occurrence of any one or more of the following events without the executive officer’s prior written consent, along with our Company’s failure to cure within 30 days after the receipt of notice thereof: (i) assignment of any duties materially inconsistent with the executive officer’s position (including status, offices, titles and reporting requirements), authority, duties or responsibilities as contemplated by the employment agreement, or any other action by our Company which results in a material diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by our Company; (ii) any material reduction of annual base salary or bonus opportunity, each as in effect on the date of the employment agreement or as the same may be increased from time to time; (iii) the relocation of our offices at which the executive officer is principally employed to a location more than 45 miles from such location, or our Company’s requiring the executive officer to be based at a location more than 45 miles from such principal place of employment, except for required travel on company business; or (iv) failure to obtain a satisfactory agreement from any successor to assume and agree to perform our Company’s obligations under the employment agreement. In addition to the above, as used in the employment agreements of Messrs. Power, Peterson, Mills and Miszewski, “good reason” includes requiring the executive officer to report to an officer other than the Chief Executive Officer; or our failure to require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume and agree to perform the employment agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Notwithstanding the foregoing, the executive officer will not be deemed to have resigned for good reason unless the executive officer provides us with notice of the circumstances constituting good reason within 60 days after the initial occurrence or existence of such circumstances, we fail to correct the circumstance so identified within 30 days after the receipt of such notice (if capable of correction), and the termination date occurs no later than 180 days after the initial occurrence of the event constituting good reason.

As used in the employment agreements of our named executive officers, “change in control” means the occurrence of any of the following events:

• a transaction or series of transactions whereby a person or group directly or indirectly acquires beneficial ownership of securities possessing more than 35% of the combined voting power of our then outstanding voting securities, subject to certain exceptions;

• individuals who, as of the date of the 2014 annual meeting of our stockholders, constitute the Board together with any new directors whose election by the Board or nomination for election by our stockholders was approved by a vote of at least a majority of the directors then still in office who either were directors as of the date of the 2014 annual meeting of our stockholders or whose election or nomination for election was previously approved, cease for any reason to constitute a majority of the Board;

• our consummation (whether directly or indirectly through one or more intermediaries) of a merger, consolidation, reorganization or business combination or a sale or other disposition of all or substantially all of our assets or the acquisition of assets or stock of another entity, in each case, other than a transaction:

– which results in our voting securities outstanding immediately before the transaction continuing to represent (either by remaining outstanding or by being converted into voting securities of the company or the person that, as a result of the transaction, controls, directly or indirectly, us or owns, directly or indirectly, all or substantially all of our assets or otherwise succeeds to our business) directly or indirectly, at least a majority of the combined voting power of the successor entity’s outstanding voting securities immediately after the transaction, and

– after which no person or group beneficially owns voting securities representing 35% or more of the combined voting power of the successor entity; or

• approval by our stockholders of our liquidation or dissolution.

Deferred Compensation Plan

The Board adopted the Digital Realty Trust, Inc. Deferred Compensation Plan (the “Deferred Compensation Plan”) on October 22, 2013. Under the Deferred Compensation Plan, as amended, eligible employees, including our named executive officers, are permitted to defer receipt of up to 100% of their base salary, bonus and/or commissions. Eligible employees, including our named executive officers, may only elect to defer compensation earned on or after January 1, 2014 under the Deferred Compensation Plan.

The amounts deferred under each participant’s Deferred Compensation Plan accounts are deemed to be invested in investment alternatives chosen by the participant from a range of choices established by our Compensation Committee, which administers the Deferred Compensation Plan. The balances of participant accounts are adjusted to reflect the gains or losses that would have been obtained if the participant contributions had actually been invested in the applicable investment alternatives.

Participants may elect to defer the distribution of their account balances until the occurrence of a specified future date or event, including: (i) a future year specified by the participant, (ii) the participant’s termination of employment, (iii) the participant’s death or disability, or (iv) a change in control of the Company. Participants may also elect whether to receive distributions of their account balances in a single lump-sum amount or in annual installments to be paid over a period of two to ten years. In addition, if a participant elects to receive a distribution of his or her account balance upon a termination of employment, the participant may elect whether his or her distributions will be made or commence, as applicable, in the second through tenth calendar years following such termination of employment (a “Post-Separation Election”).

Payment of a participant’s account will be made or commence, as applicable, as follows: (i) in the case of a specified year, on the Company’s first regular payroll date to occur during the month of July (the “Payment Date”) of the year specified by the participant, (ii) in the case of a termination of employment, on the Payment Date occurring during the year immediately following such termination of employment or, if the participant has made a Post-Separation Election, on the Payment Date occurring during the second through tenth year (as applicable) following such termination of employment, (iii) in the case of death or disability, on the Payment Date occurring during the year immediately following such death or disability, as applicable, or (iv) in the case of a change in control of the Company, as soon as possible following the change in control. If a participant selects more than one distribution event, payments will be made or commence, as applicable, on the earliest selected distribution event to occur.

The Deferred Compensation Plan is administered by our Compensation Committee, which has the authority to appoint or delegate the administration of the plan to another individual or sub-committee. The Deferred Compensation Plan is an unfunded plan for tax purposes and for purposes of Title I of the Employee Retirement Income Security Act of 1974, as amended. A “rabbi trust” has been established to satisfy our obligations under the Deferred Compensation Plan.

Potential Payments upon Termination or Change in Control

Our named executive officers are entitled to full vesting of all equity awards (other than certain performance-based vesting equity awards that have not met their performance-based vesting requirement) held by them upon a qualifying termination of employment within one year following a change in control. Our named executive officers are also entitled to severance payments upon qualifying terminations of employment pursuant to the terms of their employment agreements, as set forth under “— Narrative Disclosure to Compensation Tables — Employment Agreements” above.

The following table sets forth estimates of the payments that would be made to our named executive officers (except for Mr. Miszewski, who departed the Company in August 2016 and whose severance benefits are described below) in the event that a qualifying termination of employment and/or a change in control occurs, assuming that the triggering event took place on December 31, 2016.

(1)	The amounts payable that are reflected in this column with respect to the acceleration of each named executive officer’s equity awards will only be paid once upon the occurrence of a change in control and not again in the event of a subsequent termination of employment.
(2)	Employment agreements with named executive officers also provide for outplacement counseling services for a period of 12-months following a termination without cause or for good reason, which we estimate to be a cost of approximately $16,000 per executive officer.
(3)	Pursuant to the employment agreements or equity award agreements, as applicable, with each of our named executive officers, unvested time-based equity awards will vest upon a qualifying termination of employment within one year following a change in control and unvested performance-based equity awards will vest immediately with respect to the portion of such awards determined to have met the performance condition as of the date of the change of control.

In connection with Mr. Miszewski’s departure from the Company in August 2016, he became eligible to receive certain severance payments and benefits under his amended and restated employment agreement consisting of: (i) a cash payment equal to $1,009,438 representing the sum of (a) his then-current annual base salary, (b) his target annual bonus for 2016 and (c) a prorated portion of his 2016 target annual bonus, (ii) continued health insurance coverage for up to twelve months following termination (valued at approximately $17,818), and (iii) Company-paid outplacement services for twelve months following termination (valued at approximately $16,000). In addition, Mr. Miszewski received full accelerated vesting of all outstanding time-based equity-based awards held by him (valued at approximately $479,000). Mr. Miszewski's outstanding performance-based equity awards remain subject to the terms of the respective award agreements.

2017 Salary

In February 2017, the Compensation Committee set the following base salaries for our named executive officers:

Name	2017 Salary
A. William Stein	$	1,000,000
Andrew P. Power		600,000
Jarrett B. Appleby		460,000
Scott E. Peterson		575,000
Joshua A. Mills		450,000

In reviewing and determining the 2017 base salaries of our named executive officers, the Compensation Committee considered several factors, including the significant growth of our Company, our inclusion in the S&P 500 Index and the strong performance of our Company and our executive team over the past few years, as well as competitive market practices and our pay-for-performance philosophy.

Director Compensation

We use a combination of cash and equity-based incentive compensation to attract and retain qualified non-employee director to serve on our Board. In setting non-employee director compensation, we consider the significant amount of time that directors spend in fulfilling their duties to our Company as well as the skill level we require of members of our Board.

Compensation of Directors

Cash Compensation

On August 10, 2016, the Board approved certain changes to the director compensation program, including the addition of a cash retainer for the position of Vice Chairman of the Board and revised annual fees for service on a committee of the Board. These changes became effective as of May 10, 2016. The following tables show the annual cash retainers and Board committee fees for our non-employee directors under the current and previous director compensation programs:

Annual Cash Retainers for Non-Employee Directors	Current		Previous
Board Member	$	75,000	$	75,000
Chairman of the Board(1)	$	50,000	$	50,000
Vice Chairman of the Board(1)	$	25,000		N/A

(1) In addition to the annual cash base retainer of $75,000.

	Current				Previous
Board Committee Fees	Chairperson		Member		Chairperson		Member
Audit Committee	$	30,000	$	15,000	$	20,000	$	10,000

Nominating and Corporate Governance Committee	$	25,000	$	15,000	$	15,000	$	7,500

Equity Compensation

On August 10, 2016, the Board also approved changes to director equity compensation. The Company’s 2014 Plan currently provides for formulaic grants of long-term incentive units to non-employee directors as follows (changes to equity programs are denoted in parentheses):

• Pro Rata Grant. Commencing as of August 10, 2016, each person who first becomes a non-employee director on a date other than the date of an annual meeting of stockholders will, on the date of such person first becoming a non-employee director, be granted a number of long-term incentive units equal to the product of (A) the quotient obtained by dividing (x) $145,000 ($125,000 under the previous program) by (y) the fair market value of a share of Common Stock on such date, multiplied by (B) the quotient obtained by dividing (x) 12 minus the number of months that have elapsed since the immediately preceding annual meeting of stockholders, by (y) 12. In addition to the foregoing pro-rata grant, if applicable, each person who first becomes the Chairman of the Board on a date other than the date of an annual meeting of stockholders will, on the date of such person first becoming the Chairman of the Board, be granted a number of long-term incentive units equal to the product of (A) the quotient obtained by dividing (x) $100,000 by (y) the fair market value of a share of Common Stock on such date, multiplied by (B) the quotient obtained by dividing (x) 12 minus the number of whole months that have elapsed since the immediately preceding annual meeting of stockholders, by (y) 12. The awards will be fully vested on the date of grant.

• Annual Grant. Commencing as of the first annual meeting of stockholders to occur after the Company’s 2016 annual meeting, each person who first becomes a non-employee director at an annual meeting of stockholders and each person who otherwise continues to be a non-employee director immediately following such annual meeting will, on the date of such annual meeting, be granted a number of long-term incentive units equal to the quotient obtained by dividing (x) $145,000 ($125,000 under the previous program) by (y) the fair market value of a share of Common Stock on the date of such annual meeting. In addition to the foregoing annual grant, each person who first becomes Chairman of the Board at an annual meeting of stockholders or such person who otherwise continues to be the Chairman of the Board immediately following such annual meeting as applicable will, on the date of such annual meeting, be granted a number of

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    58

long-term incentive units equal to the quotient obtained by dividing (x) $100,000 by (y) the fair market value of a share of Common Stock on the date of such annual meeting. A director who is also an employee who subsequently incurs a termination of employment and remains on the Board will not receive a pro-rata grant, but, to the extent such director is otherwise eligible, will receive annual grants after such termination of his status as an employee. The awards will be fully vested on the date of grant.

In addition, the non-employee director may elect in advance to receive in lieu of his or her annual unit award an equivalent number of shares in the form of a stock payment or restricted stock, as applicable, subject to the same vesting schedule (if any) as would have applied to the corresponding grant of long-term incentive units. If a non-employee director does not qualify as an “accredited investor” within the meaning of Regulation D of the Securities Act of 1933, as amended (the “Securities Act”), on the date of any grant of long-term incentive units to such director, then the director will not receive such grant of long-term incentive units, and in lieu thereof will automatically be granted an equivalent number of shares in the form of a stock payment or restricted stock, as applicable, subject to the same vesting schedule (if any) as would have applied to the corresponding grant of long-term incentive units.

The table below summarizes the compensation we paid to directors during the year ended December 31, 2016:

Compensation Risk Assessment

The Company believes that our compensation policies and practices appropriately balance near-term performance with sustainable long-term value creation, and that they do not encourage unnecessary or excessive risk taking. In November 2016, the Company’s management conducted an extensive review of the design and operation of our compensation program and its findings were presented to the Compensation Committee and the Board. The review included an assessment of the level of risk associated with the various elements of compensation. Based on this review and assessment, the Company believes that our compensation policies and practices are not reasonably likely to have a material adverse effect on the Company.

ITEM 3. Advisory Vote on the Compensation of Named Executive Officers (Say-On-Pay)

Background

We are asking stockholders to vote upon a resolution to approve, on a non-binding, advisory basis, the compensation of our named executive officers as reported in this Proxy Statement (a say-on-pay vote).

At our 2011 Annual Meeting of Stockholders, the majority of the votes cast by our stockholders were in favor of holding a say-on-pay vote every year. The Board took into account this strong preference for an annual vote and determined that we will hold a non-binding, advisory vote on the compensation of our named executive officers every year unless the Board modifies its policy following the next non-binding, advisory vote on the frequency of say-on-pay votes (which is being voted on by our stockholders this year — see Item 4 of this Proxy Statement for additional information).

Summary

At our 2016 Annual Meeting of Stockholders, our stockholders overwhelmingly approved the compensation of our named executive officers, with 95% of the votes cast in favor of the say-on-pay proposal. We believe this affirms our stockholders’ support of our approach to executive compensation.

As described more fully in the Compensation Discussion and Analysis, or CD&A, section of this Proxy Statement, the compensation program for our named executive officers is designed to attract, retain and motivate experienced and talented executives who can help achieve short-term and long-term performance goals to maximize stockholder value. The program seeks to align a significant portion of executive compensation with our performance on a short-term and long-term basis through a combination of annual base salaries, annual incentives through cash bonuses and long-term incentives through equity-based compensation. The annual incentive payout for each named executive officer is based on financial and operational goals and organizational development goals established by the Compensation Committee, and each named executive officer’s bonus opportunity provides for target and maximum bonus amounts, expressed as a percentage of base salary. Long-term incentive awards include grants of long-term incentive units in our Operating Partnership intended to encourage actions to maximize stockholder value. We urge our stockholders to review the CD&A section of this Proxy Statement and executive-related compensation tables for more information.

We emphasize pay-for-performance. Our compensation philosophy is to pay for performance, support our business strategies, and offer competitive compensation arrangements. In the CD&A, we have provided stockholders with a description of our compensation programs, including the philosophy and strategy underpinning the programs, the individual elements of the compensation programs, and how our compensation plans are administered.

During the past several years, the Company has been focused on growing our operations internally and through strategic acquisitions as well as through improved leasing, asset management and marketing activities, improving our balance sheet, strategically accessing the capital markets and focusing on our organizational development. More recently, the Company has focused on its product strategy, investing in strategic initiatives to complement its existing portfolio in order to attract a wider base of customers, and organizational structuring to support these new strategies and initiatives as well as the continued growth of the Company. Accomplishments in the year ended December 31, 2016 include, among other things, the following:

• Reported FFO of $5.67 per share and unit for the year ended December 31, 2016. (A reconciliation of FFO to net income is included on page 82 of our Annual Report on Form 10-K for the year ended December 31, 2016.)

• In January 2016, completed the refinancing of our global revolving credit facility and term loan. In conjunction with the refinancing, pricing was tightened by 10 basis points, the maturity date was extended by more than two years and aggregate commitments were expanded by $550 million.

• In July 2016, completed the acquisition of a portfolio of eight high-quality, carrier-neutral data centers in Europe from Equinix in a transaction valued at approximately $819 million.

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    61

• Completed our inaugural Eurobond offering of EUR 600 million aggregate principal amount of Digital Euro Finco, LLC’s 2.625% Guaranteed Notes due 2024.

• Completed acquisitions of four land parcels in Asbhurn, VA, Franklin Park, IL and Garland, TX for a total purchase price of $48 million.

• Completed the sale of six assets in various markets during 2016 for total net proceeds of $364 million.

• Increased the annual dividend on our Common Stock by 3.5% in 2016 from 2015, representing a compound annual growth rate of 12%, since our first full quarter of operations following our initial public offering in 2004.

In 2016, we achieved the maximum level of our FFO goal, which we also achieved in 2015. Annual incentive bonuses earned by our named executive officers (excluding Mr. Miszewski) in 2016 ranged from 115% to 135% of their respective target bonuses.

The long-term incentive awards granted to our named executive officers are subject to performance vesting based on total stockholder return relative to the MSCI US REIT Index, or RMS, over a three-year measurement period and are subject to further time vesting over a one-year period following the conclusion of the measurement period.

We believe that our compensation programs are strongly aligned with the long-term interests of our stockholders. We believe that equity awards serve to align the interests of our named executive officers with those of our stockholders by encouraging long-term performance. As such, equity awards are a key component of our executive compensation program, with equity awards ranging between 52% and 71% of our named executive officers’ compensation opportunity in 2016. The performance-based equity awards granted in 2016 generally time-vest over a one-year period following the end of the applicable three-year performance period.

We are committed to having strong governance standards with respect to our compensation program, procedures and practices. Pursuant to our commitment to strong governance standards, the Compensation Committee is comprised solely of independent directors. The Compensation Committee retained FPL as an independent compensation consultant to provide it with advice and guidance on our executive compensation program design and to evaluate our executive compensation program. The Compensation Committee oversees and periodically assesses the risks associated with our compensation policies and practices company-wide to determine whether such policies and practices encourage unnecessary or excessive risk taking.

We provide competitive pay opportunities. The Compensation Committee consistently reviews our executive compensation program to ensure that it provides competitive pay opportunities. Our compensation programs consist of elements designed to complement each other and reward achievement of short-term and long-term objectives tied to our performance through association with an operating metric. We have chosen the selected metrics to align employee compensation, including compensation for the executive officers named in the Summary Compensation Table of this Proxy Statement, to our business strategy. The following are a few key 2016 actions and decisions with respect to our compensation program:

• As with past years, the named executive officers were eligible to earn cash incentive compensation based upon achievement of specific financial, operational and organizational objectives for 2016, as approved by the Compensation Committee, that are designed to challenge the named executive officers to high performance.

• A significant portion of our named executive officers’ total cash compensation remains dependent on Company, business group and individual performance.

• The Compensation Committee determines annual base salaries after reviewing salary survey data of, and the Company’s historical performance relative to, its peer group.

• Our compensation programs encourage employees to build and maintain an ownership interest in the Company. In addition to performance-based vesting, 2016 annual equity awards granted to our named executive officers are subject to time-based vesting following the end of the applicable three-year performance period.

• In 2016, FPL was retained directly by and reported to the Compensation Committee. FPL did not have any prior relationship with any of our named executive officers.  

• Base salaries represented 11% to 28% and performance-based equity compensation represented 45% to 65% of the total compensation opportunity for our named executive officers reflecting our philosophy of paying for performance and aligning the interests of our named executive officers with stockholders’ interests.

• Based on the recommendations of management, a review of the Company’s business plan and strategic objectives and the analysis provided by FPL, the Compensation Committee established financial, leasing, profitability and individual goals for each named executive officer for 2016.

Recommendation

The Board believes that the information provided above and within the CD&A section of this Proxy Statement demonstrates that our executive compensation program was designed appropriately and is working to ensure that management’s interests are aligned with our stockholders’ interests to support long-term value creation. Further, in taking the Company’s recent stock performance under consideration and awarding longer-term equity awards based on the Company’s stock performance over a three-year period, the Board believes it has further aligned our management’s interests with that of our stockholders.

In accordance with Section 14A of the Exchange Act and the Board’s determination to hold a say-on-pay vote on an annual basis, and as a matter of good corporate governance, we are asking stockholders to approve, on a non-binding, advisory basis, the following resolution at the Annual Meeting:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion of this Proxy Statement, is hereby approved, on a non-binding, advisory basis, by the stockholders of the Company.”

This advisory resolution is non-binding on the Board. Although non-binding, the Board and the Compensation Committee will carefully review and consider the voting results when evaluating our executive compensation program. We are holding an advisory vote this year on the frequency of future say-on-pay votes — see “Item 4. Advisory Vote on Frequency of Say-on-Pay Votes” of this Proxy Statement. Unless the Board modifies its policy on the frequency of future say-on-pay votes following this year’s vote, the next say-on-pay vote will be held at the 2018 Annual Meeting of Stockholders.

The affirmative vote of a majority of the votes cast at the Annual Meeting for the adoption of this resolution is required to approve, on a non-binding, advisory basis, the compensation of the named executive officers disclosed in this Proxy Statement pursuant to Item 402 of Regulation S-K under the Securities Act and the Exchange Act.

 

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    63

ITEM 4. Advisory Vote on the Frequency of Say-On-Pay Votes

Pursuant to Section 14A of the Exchange Act, which was added under the Dodd-Frank Wall Street Reform and Consumer Protection Act, we are asking stockholders to vote on a non-binding, advisory basis as to whether future votes on the compensation of our named executive officers (i.e., future say-on-pay votes) should occur every year, every two years or every three years. We are providing stockholders the option of selecting a frequency of one, two or three years, or abstaining. We last held an advisory vote on frequency of future advisory votes on the compensation of named executive officers in 2011 and the majority of the votes cast by our stockholders were in favor of holding a say-on-pay vote every year. Accordingly, we have held advisory votes on the compensation of named executive officers on an annual basis since 2011.

Summary

After careful consideration, the Board recommends that future advisory votes on the compensation of our named executive officers occur every year (annually). Our Board believes that holding a vote every year is the most appropriate option because it would enable our stockholders to continue to provide us with input regarding the compensation of our named executive officers on a timely basis.

Recommendation

Based on the factors discussed above, the Board has determined to recommend that future advisory votes on executive compensation occur every year until the next frequency advisory vote. The next advisory vote on the frequency of holding a say-on-pay vote (after this year’s vote) will occur no later than the 2023 Annual Meeting of Stockholders.

Stockholders will be able to specify one of four choices for this proposal on the proxy card: one year, two years, three years or abstain. Stockholders are not voting to approve or disapprove the Board’s recommendation, but rather to indicate their choice among these frequency options. Although the Board intends to consider the results of this advisory vote on the frequency of future say-on-pay votes held by the Company, the voting results are non-binding on the Board. Notwithstanding the Board’s recommendation and the outcome of the stockholder vote, the Board may in the future decide to conduct advisory votes on a more or less frequent basis and may vary its practice based on factors such as discussions with stockholders and the adoption of material changes to compensation programs.

In order for any of the three alternative frequencies to be approved, it must receive a majority of the votes cast on this proposal. In the event that no option receives a majority of the votes cast, we will consider the option that receives the most votes to be the option selected by the stockholders.

Indemnification Agreements

We have entered into indemnification agreements with all of our named executive officers and other executive officers and with each of our directors that obligate us to indemnify them to the maximum extent permitted by Maryland law. The indemnification agreements provide that:

•	If a director or executive officer is a party or is threatened to be made a party to any proceeding, other than a proceeding by or in the right of our Company, by reason of such director’s or executive officer’s status as a director, officer or employee of our Company, we must indemnify such director or executive officer for all expenses and liabilities actually and reasonably incurred by him or her, or on his or her behalf, unless it has been established that:
	– the act or omission of the director or executive officer was material to the matter giving rise to the proceeding and was committed in bad faith or was the result of active and deliberate dishonesty;
	– the director or executive officer actually received an improper personal benefit in money, property or other services; or
	– with respect to any criminal action or proceeding, the director or executive officer had reasonable cause to believe that his or her conduct was unlawful.
•	If a director or executive officer is a party or is threatened to be made a party to any proceeding by or in the right of our Company to procure a judgment in our Company’s favor by reason of such director’s or executive officer’s status as a director, officer or employee of our Company, we must indemnify such director or executive officer for all expenses and liabilities actually and reasonably incurred by him or her, or on his or her behalf, unless it has been established that:
	– the act or omission of the director or executive officer was material to the matter giving rise to the proceeding and was committed in bad faith or was the result of active and deliberate dishonesty; or
	– the director or executive officer actually received an improper personal benefit in money, property or services;
	provided, however, that we will have no obligation to indemnify such director or executive officer for all expenses and liabilities actually and reasonably incurred by him or her, or on his or her behalf, if it has been adjudged that such director or executive officer is liable to us with respect to such proceeding.

|  DIGITAL REALTY TRUST, INC.  |  2017 PROXY STATEMENT  |    66

•	Upon application of a director or executive officer of our Company to a court of appropriate jurisdiction, the court may order indemnification of such director or executive officer if:
	–the court determines that such director or executive officer is entitled to indemnification under the applicable section of the Maryland General Corporation Law (the “MGCL”), in which case the director or executive officer shall be entitled to recover from us the expenses of securing such indemnification; or
	– the court determines that such director or executive officer is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, whether or not the director or executive officer has met the standards of conduct set forth in the applicable section of the MGCL or has been adjudged liable for receipt of an improper personal benefit under the applicable section of the MGCL;
	provided, however, that our indemnification obligations to such director or executive officer will be limited to the expenses actually and reasonably incurred by him or her, or on his or her behalf, in connection with any proceeding by or in the right of our Company or in which the officer or director shall have been adjudged liable for receipt of an improper personal benefit under the applicable section of the MGCL.
•	Notwithstanding, and without limiting any other provisions of the agreements, if a director or executive officer is a party or is threatened to be made a party to any proceeding by reason of such director’s or executive officer’s status as a director, officer or employee of our Company, and such director or executive officer is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such proceeding, we must indemnify such director or executive officer for all expenses actually and reasonably incurred by him or her, or on his or her behalf, in connection with each successfully resolved claim, issue or matter, including any claim, issue or matter in such a proceeding that is terminated by dismissal, with or without prejudice.
•	We must pay all indemnifiable expenses in advance of the final disposition of any proceeding if the director or executive officer furnishes us with a written affirmation of the director’s or executive officer’s good faith belief that the standard of conduct necessary for indemnification by our Company has been met and a written undertaking to reimburse us if a court of competent jurisdiction determines that the director or executive officer is not entitled to indemnification.
•	We must pay all indemnifiable expenses to the director or executive officer within 20 calendar days following the date the director or executive officer submits proof of the expenses to us.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Other Matters

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires the Company’s executive officers and directors, and persons who own more than 10% of a registered class of the Company’s equity securities (“Reporting Persons”), to file reports of ownership and changes in ownership with the SEC. Reporting Persons are required by SEC regulations to furnish us with copies of all forms they file pursuant to Section 16(a). Based solely on our review of the copies of such reports received by us, and written representations from certain Reporting Persons that no other reports were required for those persons, we believe that, during the year ended December 31, 2016, the Reporting Persons met all applicable Section 16(a) filing requirements, with the exception of the following: one late Form 4 filing for each of A. William Stein, Scott E. Peterson, Andrew P. Power and Joshua A. Mills covering one transaction each with respect to the Company and the Operating Partnership, and one late Form 4 filing for Edward F. Sham covering one transaction with respect to the Company.

• any beneficial owner of shares of stock of the Company owned of record or beneficially by such stockholder (other than a stockholder that is a depositary) and

• any person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, such stockholder or such Stockholder Associated Person.

The notice must also contain and be accompanied by certain additional information as specified in our Bylaws, including information about the stockholder providing the notice, the proposed nominee and other information as we may reasonably require. Stockholders making nominations must provide, among other things, information regarding each such stockholder’s, any Stockholder Associated Person’s and their affiliates’ ownership of Company securities (beneficially or of record) including any right to acquire additional securities in the future, proxy or voting agreements with respect to the Company securities, holdings of “synthetic equity,” derivatives, hedges or short positions and other material interests and relationships that could influence nominations or proposals and other information that would be required in a proxy statement. Additionally, a stockholder nominating a director candidate is required to disclose the same information about the proposed nominee that would be required if the proposed nominee were submitting a proposal, and the proposed nominee is required to complete a questionnaire and certify that such proposed nominee (i) has not and will not become a party to any agreement, arrangement or understanding with any person or entity other than the Company in connection with service or action as a director that has not been disclosed to the Company and (ii) will serve as director if elected. Such information must be updated and supplemented so as to be accurate. We recommend that any stockholder wishing to nominate a director at an annual meeting review a copy of our Bylaws.

Any director nominations received from stockholders will be evaluated in the same manner that nominees suggested by Board members, management or other parties are evaluated.

You may write to our Secretary at our principal executive office, Four Embarcadero Center, Suite 3200, San Francisco, CA 94111, to deliver the notices discussed above and for a copy of the Bylaws.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (such as banks and brokers) to satisfy the delivery requirements for proxy materials with respect to two or more stockholders sharing the same address by delivering a single copy of the proxy statement, annual report or Notice of Internet Availability of Proxy Materials, as applicable, addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are our stockholders will be householding our proxy materials. A single Notice of Internet Availability of Proxy Materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the impacted stockholders. Once you have received notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive separate proxy materials, please notify your broker, direct your written request to Investor Relations, Digital Realty Trust, Inc., Four Embarcadero Center, Suite 3200, San Francisco, CA 94111, or contact Investor Relations by telephone at (415) 738-6500. Upon written or oral request to Investor Relations, Digital Realty Trust, Inc., Four Embarcadero Center, Suite 3200, San Francisco, CA 94111, or by telephone at (415) 738-6500 from a stockholder at a shared address to which a single copy of the proxy materials was delivered, we will promptly deliver a separate copy of the proxy materials to such requesting stockholder. Stockholders who currently receive multiple copies of proxy materials at their address and would like to request householding of their communications should contact their broker.

By Order of Our Board of Directors,

 

Joshua A. Mills

Secretary
