Ratification of Ernst & Young LLP as Independent Registered Public Accounting Firm
Our Board recommends that stockholders vote to ratify the Audit Committee's appointment of Ernst & Young LLP, an independent registered public accounting firm, as our Company's independent registered public accounting firm for the fiscal year ending December 31, 2017.
Advisory Vote on Executive Compensation
Our Board recommends that stockholders vote to approve, on an advisory basis, the compensation paid to our Named Executive Officers (" NEOs ") in 2016, as described in this Proxy Statement. At our 2016 Annual Meeting of Stockholders, our stockholders showed strong support for our executive compensation with 99.1% of the shares voted in favor of the advisory vote on executive compensation. Although the results of the "say on pay" vote are advisory and not binding on our Company, our Board or our Compensation Committee, we value the opinions of our stockholders and take the results of the say on pay vote in to account when making decisions regarding the compensation of our NEOs. The Compensation Committee of our Board evaluates our executive compensation program each year in an effort to ensure it is in line with our stockholders' interests.
We encourage stockholders to take into account the significant changes to our executive compensation program that we have made over the last several years in light of the advisory vote including, among other things, designing a new, updated compensation philosophy, transitioning to a three-year business plan for our long-term equity incentive plan, enhancing our executive stock ownership guidelines and our annual stockholder outreach program.

Table of Contents

Advisory Vote on Frequency of Future Advisory Votes on Executive Compensation
Our Board recommends that stockholders vote to approve, on an advisory basis, that we hold future advisory votes on executive compensation on an annual basis. Our Board’s recommendation was influenced by the fact that the compensation of our NEOs is evaluated, adjusted and approved on an annual basis. As part of the annual review process, our Board believes that stockholder sentiment should be a factor that is taken into consideration by our Board and our Compensation Committee in making decisions with respect to executive compensation. By holding an advisory vote on executive compensation on an annual basis, our stockholders will be able to provide us with direct input on our compensation philosophy, policies and practices as disclosed in our proxy statement every year. We understand that our stockholders may have different views as to what is the best approach for Synchronoss, and we look forward to hearing from our stockholders on this agenda item every year. Accordingly, our Board recommends that future advisory votes on executive compensation be held every year.
Fiscal 2016 Compensation
The following material decisions were approved by our Compensation Committee regarding the 2016 compensation of our NEOs:
 	 	
•	Adjustments to Base Salary: In reviewing the base salaries of Messrs. Waldis and Garcia in early 2016, our Compensation Committee approved salary increases to each of them of approximately 3% (representing the median base salary increase). In addition, each of Ms. Rosenberger's and Mr. Prague's base salary was below the competitive range of similarly situated roles at our peer group companies and based on this and other publicly-available information, they received base salary increases of 9% and 6%, respectively. As a result of his promotion to Executive Vice President, Sales in January 2016, Mr. Putnam received a base salary increase of 36% based on our Compensation Committee's review of the base salaries of similarly situated employees at our peer group companies and other publicly-available information.	
 	 	
•	Performance-based Cash Bonus:    Our 2016 Adjusted Non-GAAP revenue and Adjusted Non-GAAP EBITDA were above the target set by our Board for 2016 but below the maximum level. As a result, our NEOs (other than Mr. Putnam) received approximately 113% of their target cash incentive bonus amounts with respect to the corporate goal portion. Messrs. Waldis, Garcia and Prague and Ms. Rosenberger received 100% of their target bonus amounts for the individual component portion. Due to his role as Executive Vice President, Sales, our Compensation Committee determined that Mr. Putnam' cash incentive bonus would be based 100% on certain individual objectives, all of which he met and therefore he received 100% of his target cash incentive bonus.	

•	Performance-based Equity:    As part of the transition to a three-year long term incentive plan in 2015, each NEO received a one-time transition equity award to address the vesting opportunity 'gap' between the old and new plans. Vesting of this transition equity award was contingent upon the achievement of non-GAAP revenue, non-GAAP EBITDA and non-GAAP Cloud revenue goals both in 2015 and 2016. With respect to the portion of the transition equity awards earned with respect to 2016 performance, our 2016 non-GAAP revenue and non-GAAP EBITDA were above the target set by our Board for 2016 but below the maximum performance level. Our 2016 non-GAAP Cloud revenue was above the minimum threshhold level but below target. As a result, our NEOs were issued an aggregate of 35,727 restricted shares of our Common Stock, or 101% of the target number of performance-based restricted shares under the 2015-2016 performance-based restricted stock awards.	
 	 	
•	Time-Based Equity:    Our NEOs were granted (i) an aggregate of 122,463 time-based restricted shares of our Common Stock and (ii) stock options to purchase an aggregate of 299,184 shares of our Common Stock.

Q:	How do I vote at the Annual Meeting?	
 	 	
A:	Stockholder of Record: Shares Registered in Your Name	

If on March 27, 2017 your shares were registered in your name with the Company's transfer agent, American Stock Transfer & Trust Company, then you are a stockholder of record and may vote in person at the Annual Meeting or vote by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy on the Internet or via telephone as instructed below or submit your proxy card, if you have requested one, to ensure your vote is counted.
If you are a stockholder of record, you may vote in person at the Annual Meeting or by one of the following methods:
 	 	
•	By Internet — You may vote by proxy via the Internet at www.proxyvote.com by following the instructions provided in the Notice or, if you requested printed copies of the proxy materials by mail, by following the instructions provided in the proxy card.	
 	 	
•	By Telephone — You may vote by proxy by telephone by following the instructions provided in the Notice or, if you requested printed copies of the proxy materials by mail, by calling the toll free number found on the proxy card.	
 	 	
•	By Mail — If you request printed copies of the proxy materials by mail, you will receive a proxy card and you may vote by proxy by filling out the proxy card and returning it in the envelope provided.	
Please note that the Internet and telephone voting facilities for stockholders of record is available 24 hours a day and will close at 11:59 p.m., Eastern Time on May 15, 2017. The individuals named as proxies will vote your shares in accordance with your instructions.
We provide Internet proxy voting to allow you to vote your shares on-line, with procedures designed to ensure the authenticity and correctness of your proxy vote. However, please be aware that you must bear any costs associated with your
 
Internet access, such as usage charges from Internet access providers and telephone companies.
Beneficial Owner: Shares Registered in the Name of a Broker or Bank
If on March 27, 2017 your shares of Common Stock were held in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in "street name" and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you may direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the Annual Meeting, provided you have proof of your share ownership (such as a brokerage statement showing that you owned shares as of March 27, 2017) and a form of photo identification. However, since you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you request and obtain a valid proxy from your broker or other agent.
If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received instructions for granting proxies with these proxy materials from that organization rather than from the Company. A number of brokers and banks participate in a program provided through Broadridge Financial Services that enables beneficial holders to grant proxies to vote shares via telephone or the Internet. If your shares are held by a broker or bank that participates in the Broadridge program, you may grant a proxy to vote those shares telephonically by calling the telephone number on the instructions received from your broker or bank, or via the Internet at Broadridge's website at  www.proxyvote.com . To vote in person at the Annual Meeting, you must obtain a valid proxy from your broker, bank, or other agent. Follow the instructions from your broker, bank or other agent included with these proxy materials, or contact your broker, bank or other agent to request a proxy form.

Table of Contents

Q.	How many votes do I have?	
 	 	
A.	On each matter to be voted upon, you have one vote for each share of Common Stock you owned as of March 27, 2017.	
 	 	
Q.	What if I do not make specific voting selections?	
 	 	
A.	Stockholder of Record — If you are a stockholder of record and you:	
 	 	
•	Indicate when voting on the Internet or by telephone that you wish to vote as recommended by our Board, or	
 	 	
•	Sign and return a proxy card without giving specific voting instructions,	
then your shares will be voted "For" the election of Thomas J. Hopkins as a member of the Company's Board of Directors, " For " the ratification of Ernst & Young LLP as the Company's independent registered public accounting firm for its fiscal year ending December 31, 2017, " For " the approval of the compensation of the Company's named executive officers and " For " the every " 1 Year " option for the advisory vote on the frequency of future advisory votes on executive compensation. If any other matter is properly presented at the Annual Meeting, your proxy (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.
Beneficial Owner — If you are a beneficial owner of shares of Common Stock held in street name and do not provide the organization that holds your shares with specific voting instructions then, under applicable rules, the organization that holds your shares may generally vote on "routine" matters but cannot vote on "non-routine" matters. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, that organization will inform the inspector of election that it does not have the authority to vote on any matter other than Proposal 2 with respect to your shares. This is generally referred to as a "broker non-vote."

Q.	Can I change my vote after submitting my proxy?	
 	 	
A.	Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of three ways:	
 	 	
•	You may change your vote using the Internet or telephone methods described above prior to 11:59 p.m., Eastern Time on May 15, 2017, in which case only your latest Internet or telephone proxy submitted prior to the Annual Meeting will be counted.	
 	 	
•	You may submit another properly completed timely proxy card with a later date.	
 	 	
•	You may send a written notice that you are revoking your proxy to the Company's Secretary at 200 Crossing Boulevard, Bridgewater, New Jersey 08807.	
 	 	
•	You may attend the Annual Meeting and vote in person. Simply attending the meeting will not, by itself, revoke your previously delivered proxy.	
If you are a beneficial owner of your shares and wish to change or revoke your previously delivered proxy, you must contact the broker, bank or other agent holding your shares and follow their instructions for changing your vote.
 	 	
Q.	Who is paying for this proxy solicitation?	
 	 	
A.	The Company will pay for the entire cost of soliciting proxies for the Annual Meeting. In addition to the proxy materials, our directors and employees may also solicit proxies in person, by telephone or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. The Company may reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials.	
 	 	
Q:	Why did I receive a notice regarding the availability of proxy materials on the Internet instead of a full set of proxy materials?	
 	 	
A:	In accordance with the rules promulgated by the SEC, we have elected to furnish our proxy materials, including this Proxy

Table of Contents

Statement and our annual report to our stockholders, primarily via the Internet. Beginning on or about April 6, 2017, we mailed to our stockholders a "Notice of Internet Availability of Proxy Materials" that contains notice of the Annual Meeting and instructions on how to access our proxy materials on the Internet, how to vote at the meeting and how to request printed copies of the proxy materials and annual report. Stockholders may request to receive all future proxy materials in printed form by mail or electronically by e-mail by following the instructions contained at  http: materials.proxyvote.com/87157B . We encourage stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce the environmental impact of our annual meetings.
 	 	
Q:	What does it mean if multiple members of my household are stockholders but we only received one Notice or full set of proxy materials in the mail?	
 	 	
A:	We have adopted a procedure called "householding," which the SEC has approved. Under this procedure, we deliver a single copy of the Notice and, if applicable, the proxy materials to multiple stockholders who share the same address unless we received contrary instructions from one or more of the stockholders at that address. This procedure reduces our printing costs, mailing costs, and fees. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written request, we will deliver promptly a separate copy of the Notice and, if applicable, the proxy materials to any stockholder at a shared address to which we delivered a single copy of any of these documents. To receive a separate copy of the Notice and, if applicable, the proxy materials, stockholders should send their requests to our principal executive offices, Attention: Secretary. Stockholders who hold shares in street name (as described below) may contact their brokerage firm, bank, broker-dealer, or other similar organization to request information about householding.	

 
Q.    How are votes counted?
 	 	
A.	Each share of Common Stock is entitled to one vote. Votes will be counted by the inspector of election appointed for the Annual Meeting. Prior to the Annual Meeting, the inspector will sign an oath to perform his or her duties in an impartial manner and according to the best of his or her ability. The inspector will determine the number of shares of Common Stock represented at the Annual Meeting and the validity of proxies and ballots, count all votes and ballots and perform certain other duties. The determination of the inspector of elections as to the validity of proxies will be final and binding.	
 	 	
Q.	What vote is required to approve each proposal?	
 	 	
•	Our directors are elected by a plurality of the votes cast at an annual meeting of stockholders, meaning the nominee(s) receiving the most "For" votes (among votes properly cast in person or by proxy) will be elected. An instruction to "Withhold" authority to vote for a nominee will result in the nominee receiving fewer votes, but will not count as a vote against the nominee. If you do not instruct your broker how to vote with respect to this proposal, your broker may not vote with respect to this proposal. Abstentions and "broker non-votes" (i.e., shares held by a broker or nominee that are represented at the Annual Meeting, but with respect to which such broker or nominee is not instructed to vote on a particular proposal and does not have discretionary voting power) will have no effect on the election of a nominee.	
 	 	
•	Ratification of the appointment by our Board of Directors of Ernst & Young LLP as the Company's independent registered public accounting firm for our fiscal year ending December 31, 2017, requires a "For" vote from the majority of all of the outstanding shares that are present in person or represented by proxy and cast affirmatively or negatively at the Annual Meeting. Abstentions and broker non-votes will not be counted "For" or "Against" this proposal and will have no effect on this proposal. Because this proposal is a routine matter, a broker or other nominee may

generally vote and therefore no broker non-votes are expected to exist in connection with this proposal.
 	 	
•	The advisory approval of the compensation of the Company's NEOs as described in this Proxy Statement requires a "For" vote from the majority of all of the outstanding shares that are present in person or represented by proxy and cast affirmatively or negatively at the Annual Meeting. Abstentions and broker non-votes will not be counted "For" or "Against" this proposal and will have no effect on this proposal. Even though your vote is advisory and therefore will not be binding on the Company, our Compensation Committee will review the voting results and take them into consideration when making future executive compensation decisions.	
 	 	
•	The advisory vote on the frequency of future advisory votes on the compensation of the Company's NEOs as described in this Proxy Statement requires a "For" vote for one of the three options presented: every "1 Year," "2 Years" or "3 Years". The option receiving the plurality of votes from the outstanding shares that are present in person or represented by proxy and cast affirmatively or negatively at the Annual Meeting will be the option deemed approved by our stockholders. Abstentions and broker non-votes will not be counted "For" or "Against" this proposal and will have no effect on this proposal. Even though your vote is advisory and therefore will not be binding on the Company, our Compensation Committee will review the voting results and take them into consideration when making future determinations about how frequently to ask the Company's stockholders to consider an advisory proposal on executive compensation.	
If there are insufficient votes to approve any of the matters, your proxy may be voted by the persons named in the proxy to adjourn
 
the Annual Meeting in order to solicit additional proxies in favor of the approval of such proposal(s). If the Annual Meeting is adjourned for any reason, at any subsequent reconvening of the meeting, your proxy will be voted in the same manner as it would have been voted at the original Annual Meeting unless you revoke or withdraw your proxy. Your proxy may be voted in this manner even though it may have been voted on the same or any other matter at a previous session of the Annual Meeting.
Q.    Is my vote confidential?
 	 	
A.	Proxies, ballots and voting tabulations are handled on a confidential basis to protect your voting privacy. This information will not be disclosed, except as required by law.	
Q.    What is the quorum requirement?
 	 	
A.	A quorum of stockholders is necessary to hold a valid stockholders meeting. A quorum will be present if a majority of the voting power of all of the Company's outstanding shares is represented by stockholders present at the Annual Meeting in person or by proxy. On the record date, there were 46,372,470 shares of Common Stock outstanding and entitled to vote. Thus, 23,186,236 shares must be represented by stockholders present at the Annual Meeting in person or by proxy to have a quorum. Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other agent) or vote in person at the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement.	
 	 	
Q.	How can I find out the results of the voting at the Annual Meeting?	
 	 	
A.	Preliminary voting results will be announced at the Annual Meeting. Final voting results will be set forth in a Current Report on Form 8-K to be filed by the Company with the SEC no later than four business days after the Annual Meeting.	
IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE
STOCKHOLDER MEETING TO BE HELD ON MAY 16, 2017.

Corporate Governance at Synchronoss	

 	
CORPORATE GOVERNANCE GUIDELINES	
Synchronoss is committed to excellent corporate governance, which we believe helps us to sustain our success and build long-term value for our stockholders. Our Board has adopted Corporate Governance Guidelines (the " Guidelines ") that set forth the framework within which our Board can effectively function and govern our affairs. The Guidelines address, among other things, the composition and responsibilities of our Board, director independence, management succession planning and evaluation, access to information, executive sessions, communication with stockholders, target ownership by and remuneration of our directors, Board committees and selection of new directors. We have also adopted a Code of Business Conduct (the " Code ") that applies to all of our employees, officers (including our principal executive officer, principal financial officer, principal accounting officer, or those serving similar functions) and directors. The Guidelines and Code are available on the Investor Relations section of our website at www.synchronoss.com .
Our Board regularly reviews legal and regulatory requirements, evolving best practices and other developments and may modify, waive, suspend or repeal the Guidelines or Code from time to time as it deems necessary or appropriate in the exercise of our Board's judgment or in the best interests of our stockholders. If we make any substantive amendments to the Guidelines or the Code, we will promptly disclose the nature of the amendment or waiver on our website to the extent required by applicable law or regulations.

BOARD LEADERSHIP STRUCTURE	
Consistent with the Guidelines, our Board believes it is important to retain its flexibility to allocate the responsibilities of our Chief Executive Officer (" CEO ") and Chairman of the Board in any way that is in the best interests of our Company based on the circumstances existing at a particular point in time. Our Board believes that it should periodically assess who should serve these roles and whether the offices should be served independently or jointly, and that our Board should not be restricted by any strict policy directive when making these decisions. In addition, our Board continually evaluates its leadership structure to ensure that the Board is structured to address the best interests of our Company and our stockholders as they evolve over time. 
Currently and effective as of January 19, 2017 when we completed our acquisition of Intralinks, our Board has determined that our Company and our stockholders are best served by having Mr. Waldis, one of our founders, serve as our Executive Chairman of the Board, and Mr. Hovsepian serve as our CEO and a member of our Board. As CEO, Mr. Hovsepian is the individual with primary responsibility for managing our day-to-day operations, setting our overall business strategy, and ensuring the successful growth of our business. Mr. Waldis' in-depth experience as our founder and long-time CEO and Chairman of the Board position him well to serve now as our Executive Chairman of the Board, where he will remain on our Board, managing our funnel for sales of new communication and media products through our transition in 2017, assisting on certain business development activities, and providing other consultative support to the CEO, upon his request

INDEPENDENCE OF OUR BOARD OF DIRECTORS	
Each year, as part of our assessment of director independence, our Nominating/Corporate Governance Committee and our full Board conduct a review of the financial and other relationships between each director, or any of their immediate family members, and our Company, our senior management, companies with whom we have business dealings and our independent registered public accounting firm. Our Board also consults with our legal counsel to ensure that its determinations are consistent with all relevant laws and regulations regarding the definition of independent, including those set forth in pertinent listing standards of the Nasdaq Global Market (" Nasdaq "), as amended from time to time. Consistent with those considerations, after review of all relevant transactions or relationships, our Board has affirmatively determined that all of our directors are independent directors within the meaning of the applicable Nasdaq listing standards except for Stephen G. Waldis, who serves as our Executive Chairman, and Ronald W. Hovsepian, who serves as our CEO. Our independent directors meet in regularly scheduled

executive sessions where only independent directors are present. Mr. Cadogan presides over those sessions. There are no family relationships among any of our directors or executive officers.

BOARD OF DIRECTORS OVERSIGHT OF RISK MANAGEMENT	
Risk is inherent with every business and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our operations, strategic direction and intellectual property as more fully discussed under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 and our other SEC filings. Assessing and managing risk is the responsibility of our management. Our Board oversees management in the execution of its responsibilities and for assessment of our approach to risk management. An overall review and assessment of risk is inherent in our Board's consideration of our business plans, strategies and other significant developments. Additionally, our Board regularly reviews various risks arising out of transactions and other matters that are presented to our Board and when making decisions impacting us. At least annually, our Board also reviews and analyzes the strategic and operational risks and opportunities that face our Company as a whole, as well as those related to specific areas of our business.
Our Board delegates the oversight of certain categories of risk affecting our Company to designated Board committees, who report their findings to our full Board. Our Audit Committee is responsible for overseeing our Board's execution of its risk management oversight responsibility, including discussing guidelines and policies governing the process by which our management assess and manage our exposure to major financial risk exposures and the steps management has taken to monitor and control such exposures, based on consultation with our management and independent auditors. Our Audit Committee also annually reviews the audit plan of management, our information technology risks and mitigation strategies, the domestic and international tax function and treasury operations and conformity with ethics and compliance standards. In addition, our Board has delegated to other Board committees the oversight of risks within their areas of responsibility and expertise. For example, our Compensation Committee oversees the risks associated with our compensation practices, including an annual assessment of our compensation policies and practices for our employees.

BOARD SELF-EVALUATION	
Our Nominating/Corporate Governance Committee oversees a biennial self-evaluation process to analyze and review our Board's performance and the performance of each of the members of our Board. The Nominating/Corporate Governance Committee reviews these results and discusses them with the full Board with the intention of utilizing them to enhance our Board's effectiveness and, if necessary, develop action plans.

STOCKHOLDER COMMUNICATIONS WITH OUR BOARD OF DIRECTORS	
Stockholders may communicate with our management and independent directors by sending a letter to Synchronoss Technologies, Inc., 200 Crossing Boulevard, Bridgewater, New Jersey 08807, Attention: Secretary. Each communication should set forth the (i) name and address of the stockholder as they appear on our books and, if the shares of our Common Stock are held by a broker, bank or other agent, the name and address of the beneficial owner of such shares, and (ii) number of shares of our Common Stock that are owned of record by such record holder and/or beneficially by such beneficial owner. Our Secretary will review all communications from stockholders and has the authority to disregard any inappropriate communications or take other appropriate actions with respect to any inappropriate communications. If deemed an appropriate communication, our Secretary will forward it, depending on the subject matter, to the chairperson of a committee of our Board or a particular director, as appropriate.

Our Audit Committee also discussed with our independent registered public accounting firm the overall scope and plans for their audit and met with them on a regular basis without members of management.

In addition to qualifying as independent under the Nasdaq rules, each member of our Audit Committee can read and has a working understanding and comprehension of fundamental financial statements. Our Board has determined that each of Donnie M. Moore and Thomas J. Hopkins is an audit committee financial expert, as defined by Item 407(d) of Regulation S-K based on a qualitative assessment of each of their level of knowledge and experience based on a number of factors, including their respective formal education and experience. The designation does not impose on either Mr. Moore or Mr. Hopkins any duties, obligations or liability that are greater than are generally imposed on them as a member of our Audit Committee and our Board, and their respective designations as Audit Committee financial experts pursuant to this SEC requirement does not affect the duties, obligations or liability of any other member of our Audit Committee or Board.

In 2016, Deloitte did not perform any services for us other than its services to our Compensation Committee and received no compensation from our Company other than its fees in connection with the firm's retention as our Compensation Committee's compensation consultant. Our Compensation Committee assessed the independence of Deloitte pursuant to applicable SEC rules and Nasdaq listing standards and concluded that the work of Deloitte has not raised any conflict of interest. Our Compensation Committee considers the information provided by Deloitte when making decisions with respect to compensation matters, along with information it receives from management and its own judgment and experience.

Candidates for nomination to our Board typically have been suggested by other members of our Board or by our executive officers. From time to time, our Nominating/Corporate Governance Committee may engage the services of a third-party search firm to identify director candidates. Our Nominating/Corporate Governance Committee also considers candidates proposed in writing by stockholders, provided those proposals meet the eligibility requirements for submitting stockholder proposals under our amended and restated bylaws and are accompanied by certain required information about the candidate in accordance with our amended and restated bylaws and organizational documents. Candidates proposed by stockholders will be evaluated by our Nominating/Corporate Governance Committee using the same criteria as for all other candidates. Stockholders may contact the Secretary at our principal executive offices for a copy of the relevant bylaw provisions regarding the requirements for making stockholder nominations and proposals. For more information pertaining to stockholder proposal, see “ Stockholder Proposals for the Next Annual Meeting .”
In considering nominees for our Board, our Nominating/Corporate Governance Committee considers each candidate's independence, personal and professional integrity, financial literacy or other professional or business experience relevant to an understanding of our business, ability to think and act independently and with sound judgment and ability to serve our stockholders' long-term interests. These factors, along with others considered useful by our Nominating/Corporate Governance Committee, are reviewed in the context of an assessment of the perceived needs of our Board at a particular point in time. As a result, the priorities and emphasis of our Nominating/Corporate Governance Committee and of our Board may change from time to time to take into account changes in our business and other trends and the portfolio of skills and experience of current and prospective directors. Our Nominating/Corporate Governance Committee has not adopted a formal policy regarding the consideration of diversity in identifying director nominees or in searching for new directors.

Our Compensation Committee annually determines a fixed monetary value of equity awards to be granted to our non-employee directors based on their analysis of the competitive range of the equity granted to directors at our peer group companies and other publicly-available information. The actual number of restricted shares and shares underlying stock options is determined based on the grant date fair value of the equity awards. The stock options have an exercise price equal to the closing price reported on Nasdaq of our Common Stock on the grant date. The annual retainer fees are paid to our directors quarterly at the beginning of each quarter. In addition, we currently have a policy of reimbursing directors for travel, lodging and other reasonable expenses incurred in connection with their attendance at our Board and Committee meetings. The following table sets forth all of the compensation awarded to, earned by, or paid to each person who served as a non-employee director during 2016.

DIRECTOR STOCK OWNERSHIP GUIDELINES	
We have established stock ownership guidelines for our directors to retain an equity stake in the Company to more closely align their interests with those of our stockholders. Each director is required to own the number of shares of our Common Stock with a value equal to three times the annual cash retainer for service on our Board. Ownership is calculated annually based on the closing sales price of our Common Stock on Nasdaq for the last trading day in the prior year. Any newly elected director has three years from the date of his or her election to achieve the targeted equity ownership level. As of December 31, 2016, each of our directors owned at least the number of shares of our Common Stock required by these guidelines based on the price of our Common Stock on such date.

LIMITATION OF LIABILITY AND INDEMNIFICATION	
As permitted by Section 145 of the Delaware General Corporation Law, our amended and restated bylaws provide that we are authorized to (i) enter into indemnification agreements with our directors and officers and (ii) purchase directors' and officers' liability insurance, which we currently maintain to cover our directors and executive officers. The form of indemnification agreement with our directors provides that we will indemnify each director against any and all expenses incurred by that director because of his status as one of our directors, to the fullest extent permitted by Delaware law, our restated certificate of incorporation and amended and restated bylaws. In addition, the form agreement provides that, to the fullest extent permitted by Delaware law, but subject to various exceptions, we will advance all expenses incurred by our directors in connection with a legal proceeding. Our restated certificate of incorporation and bylaws contain provisions relating to the limitation of liability and indemnification of directors. The restated certificate of incorporation provides that our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duty as a director, except for liability:
 	 	
•	for any breach of a director's duty in respect of unlawful (i) payments of dividends or (ii) stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law and the breach of a director's duty of loyalty to us or our stockholders;	
 	 	
•	for any transaction from which the director derives any improper personal benefit; and	
 	 	
•	for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law.	
Our restated certificate of incorporation also provides that if Delaware law is amended after the approval by our stockholders of our restated certificate of incorporation to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of our directors will be eliminated or limited to the fullest extent permitted by Delaware law. The foregoing provisions of the restated certificate of incorporation are not intended to limit the liability of directors or officers for any violation of applicable federal securities laws. As permitted by Section 145 of the Delaware General Corporation Law, our restated certificate of incorporation provides that we may indemnify our directors to the fullest extent permitted by Delaware law and the restated certificate of incorporation provisions relating to indemnity may not be retroactively repealed or modified so as to adversely affect the protection of our directors.

RISK MANAGEMENT CONSIDERATIONS	
Each year, our Compensation Committee reviews our compensation practices and policies for all employees, including our NEOs, and assesses whether they have the potential to incentivize employees without taking risks that are reasonably likely to have a material adverse effect on our Company. Since our annual performance-based bonus and equity programs are designed to align our employees' compensation with both our short- and long-term business objectives and performance, and therefore enhance stockholder value, our Compensation Committee believes that our compensation practices and policies discourage behavior that leads to excessive risk-taking. Therefore, our Compensation Committee believes our practices and policies will promote balanced risk management and are not likely to have a material adverse effect on our Company. Set forth below are the key risk-balancing elements of our compensation practices and policies:

 	Financial
Performance
Measures	The ranges set for financial performance measures are designed to reward success without encouraging excessive risk taking. Pursuant to our three-year equity plan, the number of performance-based restricted shares to be issued is based on our financial performance over a three-year period. There are maximum payouts under our cash incentive plan and the performance-based restricted shares, which help mitigate risk.	
 	Equity Vesting Periods	Time-based restricted shares typically vest over three years, while stock options typically vest over four years. The performance-based restricted shares are earned and vest upon determination of the achievement of our three-year business plan. The vesting of the equity awards is designed to reward continued service with us, increases in our stock price and achievement of corporate goals designed to enhance stockholder value.	
 	Equity Retention Guidelines	NEOs are required to acquire within five years of becoming an executive officer, and hold while they are executive officers, shares (vested and unvested) having a value of at least three times, or five times in the case of our CEO, their respective base salaries.	
 	No Hedging	NEOs are not permitted to enter into any transaction designed to hedge, or having the effect of hedging, the economic risk of owning our securities.	
 	Financial Restatement, Recoupment and Related Policies	As part of our Ethics and Business Conduct Policy, we will investigate all reported instances of questionable or unethical behavior of a director, NEO or other employee and, where improper behavior or failure to act is found to have occurred, will take appropriate action up to and including termination. If an investigation uncovers that an individual has committed fraud or other improper acts that causes our financial statements to be restated or otherwise affected, we will take immediate and appropriate disciplinary action with respect to that individual up to and including termination. We also intend to pursue whatever legal remedies are available to prosecute that individual to the fullest extent of the law and seek to recoup or recover any amounts he or she inappropriately received as a result of his or her improper actions, including but not limited to any annual or long term incentives that he or she received to the extent the individual would not have received that amount had the improper action not been taken.

Executive Summary

We believe that the programs foster a performance-oriented culture that aligns our executives' interests with those of our stockholders over the long term. We believe that the compensation of our NEOs is both appropriate for and responsive to the goal of improving shareholder value. Specifically, in 2016, the majority of each NEO's compensation was performance-based.

2016 Compensation Program Highlights
Our executive compensation program is designed to attract, retain and motivate high-quality executives and drive the creation of long-term shareholder value by tying a significant portion of executives' compensation to Company and individual performance. Our compensation philosophy and programs are designed to achieve the following objectives:

Pay for
Performance	Provide a strong relationship of pay to performance through:
• Performance-based cash bonus tied primarily to achievement of corporate short-term financial goals and individual performance.
• Equity awards that deliver value based on the performance of our Common Stock and, in the case of performance-based stock awards, the achievement of pre-determined, objective financial and business goals.	
Emphasis on
Variable
Compensation	• Total compensation is heavily weighted toward incentive compensation (i.e., annual cash bonuses and long-term equity incentives).
• Annual performance-based cash bonuses focus our NEOs on key short-term financial goals.
• Stock options and time-based and performance-based restricted shares incentivize our NEOs to focus on sustainable, long-term stockholder value creation. The value realized by our NEOs depends substantially on our long-term performance, achievement of our strategic goals and the value of our Common Stock, which we believe aligns our NEOs' interests with the long-term interests of our stockholders.	
Fixed
Compensation
Component	• Provide base salary based on our Compensation Committee's general understanding of current competitive compensation practices, corporate achievement, the role in which a NEO serves and the NEO's responsibilities, length of tenure, internal pay equity and individual performance.	
The following highlights some of the key components of our pay for performance policies and practices:

At-Risk Compensation	A majority of the compensation of our CEO and our other NEOs is "at-risk" and tied to Company performance over the short- and/or long-term.	
Incentive Award Metrics	Establish and approve difficult to achieve objective incentive award metrics tied to key Company performance indicators.	
Three-Year Performance Equity Plan	The number of performance-based restricted shares earned is based on our financial performance over a three-year period, aligning our NEOs' interests with the long-term interests of our stockholders.	
Time-Based Equity Vesting	Equity awards subject to time-based vesting vest incrementally over three or four years to promote retention.	
Stock Ownership Guidelines	Maintain stock ownership guidelines to support the alignment of interests between our NEOs and stockholders.	
No Hedging	Prohibition of hedging exposure of, or interest in, our Common Stock.	
Our Compensation Committee oversees the design and administration of the compensation programs for all our employees, with an enhanced focus on the individual compensation of our NEOs. For 2016, our CEO assessed the performance of our NEOs (other than himself), consulted with other members of management and made recommendations to our Compensation Committee regarding the amount and the form of the compensation of our NEOs and other key employees, including the performance goals, weighting of goals, and equity compensation awards of NEOs. Our CEO was not present during discussions regarding his compensation.

2016 Executive Compensation Program

Cash Incentive Compensation
For our NEOs' Annual Cash Incentive Bonuses (other than Mr. Putnam), our Compensation Committee approved the following metrics:
 	 	
•	45% based on the Company's non-GAAP revenue* for 2016;	
 	 	
•	45% based on the Company's non-GAAP EBITDA* for 2016; and	
 	 	
•	10% based on the NEO's individual performance.	
* These financial measures are non-GAAP measures and should not be reviewed in isolation or as substitutes for our financial results as reported in accordance with GAAP. Please see  Appendix A  for an explanation and reconciliation of these non-GAAP financial measures to the applicable GAAP financial measures.
Our Compensation Committee believes that non-GAAP revenue and non-GAAP EBITDA are two metrics that accurately value our Company on both a short- and long-term basis and are targeted to emphasize strong growth on gross revenue and managing expenses. Based on the feedback received as part of our stockholder outreach program, these are also two of the key metrics many of our stockholders use in their valuation of our Company. As such, our NEOs are focused on growing non-GAAP revenue and non-GAAP EBITDA, which we believe is aligned with our stockholder's perspective on our Company's ability to grow and succeed in the short- and long-term.

Since Mr. Putnam is responsible for worldwide sales, our Compensation Committee did not believe it appropriate to tie his target cash incentive bonus to corporate objectives. Instead, his cash incentive bonus was determined based entirely on achievement of individual objectives that were set for him by our Compensation Committee as recommended by our Chief Executive Officer.
Long-term Incentive Compensation
Our Compensation Committee awards time-based restricted shares, stock options and performance-based restricted shares to our NEOs as the long-term incentive compensation component of their compensation, targeting an annual mix of one-third for each of these types of equity awards (based on grant date fair value). The number of stock options, target number of performance-based restricted shares and number of time-based restricted shares granted to our NEOs is based on our Compensation Committee's general understanding of competitive pay practices, our CEO's recommendations (except for his own) and other factors it deemed appropriate.
2016-2018 Performance Shares
Our 2016 long-term equity incentive plan is designed to reward financial and strategic performance during a three-year period from 2016 through 2018, and the restricted shares granted under the 2016 long-term incentive plan (the " 2016-2018 Performance Shares ") are earned and vest based on achievement of pre-determined performance criteria during that period. Our Compensation Committee approved the following performance metrics for the 2016-2018 Performance Shares:
 	 	
•	60% are earned based on three-year average annual non-GAAP revenue* growth of our Company from 2016 to 2018;	
 	 	
•	30% are earned based on three-year average annual non-GAAP EBITDA* from 2016 to 2018; and	
 	 	
•	10% are earned based on three-year annual revenue growth in our Enterprise business from 2016 to 2018.	
* These financial measures are non-GAAP measures and should not be reviewed in isolation or as substitutes for our financial results as reported in accordance with GAAP. Please see  Appendix A  for an explanation and reconciliation of these non-GAAP financial measures to the applicable GAAP financial measures.

2016 Say on Pay Vote	
At our 2016 Annual Meeting, approximately 99.1% of the shares voted were cast in favor of the advisory vote on executive compensation. We continuously strive to improve the level of stockholder support for our executive compensation program and, in 2016, met with a majority of our largest stockholders and solicited their feedback on our executive compensation policies. Our Compensation Committee plans to evaluate our executive compensation program each year with the goal of ensuring it is in line with our stockholders' interests. We encourage stockholders to take into account the significant changes to our executive compensation program over the last several years in considering the advisory vote presented below including, among other things, designing a new, updated compensation philosophy, transitioning to a three-year business plan for our long-term equity incentive plan, enhancing our executive stock ownership guidelines and our annual stockholder outreach program.

Compensation Consultant	
Our Compensation Committee's compensation consultant generally attends regular Compensation Committee meetings and meets with our Compensation Committee without management present. When making decisions with respect to compensation matters and in an effort to gain a better understanding of the competitive landscape, our Compensation Committee considers various analyses prepared by its compensation consultant, along with information it receives from management and its own judgment and experience. Since 2013, our compensation consultant has been Deloitte Consulting LLP (" Deloitte ").

Peer Group	
Our Compensation Committee generally reviews executive compensation survey and proxy data from technology companies that have similar software/services business models or operate in the mobile networking space, are of similar financial size and are representative of the organizations with which we compete with for our executive talent. Our Compensation Committee, based in part on advice from Deloitte, identified and approved the following companies that fit some or all of these criteria as our peer group for purposes of 2016 executive compensation decisions:

Blackbaud, Inc.	Interactive Intelligence Group, Inc.	NeuStar, Inc.	
Bottomline Technologies, Inc.	J2 Global, Inc.	Pegasystems, Inc.	
CommVault Systems, Inc.	LogMein, Inc.	Progress Software Corp.	
Cornerstone OnDemand Inc.	Medidata Solutions, Inc.	SolarWinds Inc.	
Fleetmatics Group PLC	Microstrategy, Inc.	The Ultimate Software Group	
Guidewire Software Inc.	 	 	
Our peer group was updated in 2016 to reflect the acquisition of Compuware Corporation in late 2014 and the acquisition of Advent Software, Inc., Aruba Networks, Inc., Digital River, Inc. and Informatica Corporation in 2015. To offset the removal of these five companies, we added Cornerstone OnDemand Inc., Guidewire Software Inc., Interactive Intelligence Group, Inc., Pegasystems, Inc., Progress Software Corp. and SolarWinds Inc. based on the similarities of their business offerings, financial profile, market capitalization and profitability with those of our Company. As a result of these changes, we believe the peer group utilized for purposes of 2016 executive compensation decisions was representative of companies that we compete with for executive talent.
When making compensation decisions for our NEOs, our Compensation Committee also reviews published survey and peer group compensation data for other software/services companies. As we continue to grow as a company, competitive market practices become an increasingly important factor in our Compensation Committee's decision-making process, although the Committee's decisions are not entirely based upon these factors and it is not bound by any target specific compensation levels derived from peer group data. Rather, our Compensation Committee reviews and considers the peer group and other survey data to obtain a general understanding of current competitive compensation practices. Utilization of the peer group and survey data to gain a general understanding of competitive pay practices allows us to accomplish our goal of paying our NEOs what is appropriate and necessary to attract qualified and committed executives while incentivizing achievement of our corporate goals while conserving cash and equity.

Principal Elements of Compensation
Our executive compensation program has the following principal elements: base salary, annual cash incentive bonuses, equity awards and severance and change in control benefits. For base salary, annual cash bonuses and equity awards for our executive officers, generally our Company’s compensation philosophy is to evaluate individual experience and contribution, as well as corporate performance, and then factor in competitive market analysis. The markets we are serving are narrow and highly competitive for large-scale implementations leveraging unique technologies. With respect to all compensation components, we generally target pay to be competitive with the median of our peer group and the markets for which we compete for talent. During the coming transformative years, where we seek to drive our Company to over-perform the market in the long term, we believe that to ensure an appropriate pay-for-performance alignment, it may be appropriate for our Compensation Committee to approve compensation levels for individual executives that may be above or below target pay for similar positions based on experience, individual contribution, corporate performance and competitive analysis. Additionally, our Compensation Committee may exercise discretion to issue one-time equity awards where appropriate to ensure alignment with key strategic business initiatives. The following table sets forth the primary compensation elements used by our Company and the objectives of each element:

Base Salary	Objective:	
​	Our Compensation Committee sets base salaries with the intent to attract and retain executives, reward satisfactory performance and provide a minimum, fixed level of cash compensation to compensate NEOs for their day-to-day responsibilities.	
​	Key Features:	
​	•	 	Executive base salaries are initially determined as a result of negotiation between the executive and our management in consultation with, and subject to the approval of, our Compensation Committee.	
​	•	 	Our Compensation Committee reviews base salaries annually and has discretion to provide increases based on our Compensation Committee's understanding of current competitive pay practices, promotions, our CEO's recommendation (except in the case of his own salary), changes in responsibilities and performance, annual budget for increases, our overall financial and operational results, the general economy, length of tenure and internal pay equity and other factors our Compensation Committee deems appropriate.	
​	Process:	
​	•	 	At the end of each calendar year, our CEO recommends base salaries for executives other than himself for the following calendar year.	
​	•	 	Our Compensation Committee reviews proposed base salary changes with input from its compensation consultant.	
​	•	 	Our Compensation Committee approves base salaries for our NEOs.	
​	•	 	Our Compensation Committee reports base salary determinations to our full Board.

Annual Cash	Objective:	
Incentive Bonus	Annual cash incentive bonuses are awarded under a performance-based compensation program and are designed to align the interests of our NEOs and stockholders by providing compensation based on the achievement of pre-determined corporate and/or business goals and individual performance.	
 	Key Features:	
 	•	Each year, the target bonus for each NEO is set by our Compensation Committee based on the provisions of each NEO's employment agreement, our CEO's recommendation (except in the case of his own target), internal pay equity, our Compensation Committee's general understanding of current competitive pay practices and other factors it deems appropriate.	
 	•	At least 90% of the incentive compensation for our NEOs other than Mr. Putnam is based on achievement of certain objective corporate financial goals established and approved by our Compensation Committee at the start of the year. Because Mr. Putnam is responsible for our worldwide sales, our Compensation Committee determined that his cash incentive bonus would be determined based entirely on achievement of individual objectives.	
 	•	If we achieve results that are below certain threshold levels, these NEOs receive no cash incentive bonus, while results that are above certain threshold levels result in cash incentive bonuses above target levels.	
 	Process:	
 	•	Our Compensation Committee participates in our Board's review of our annual operating plan at the beginning of the year.	
 	•	Our CEO recommends bonus targets as a percentage of base salary for each NEO other than himself.	
 	•	Our management recommends financial and other performance measures, weightings and ranges.	
 	•	Our Compensation Committee reviews proposed bonus targets, performance measures and ranges provided by management and, with input from its compensation consultant, approves bonus targets, performance measures and ranges that it believes establish appropriately challenging goals.	
 	•	After the end of the fiscal year, our management presents the Company's financial results to our Board.	
 	•	Our CEO recommends the individual component award for each of our NEOs other than himself.	
 	•	Our Compensation Committee reviews the results and determines whether to make any adjustments to the recommendations and then approves each NEO's bonus award.	
 	•	Our Compensation Committee reports bonus award determinations to our full Board.	
Equity Awards	Objectives:	
​	Our Compensation Committee structures equity awards to align our NEOs' interests with those of our stockholders, support retention and motivate NEOs to achieve our financial, strategic and operational goals. Equity awards include stock options and time-based and performance-based restricted shares.	
​	Key Features:	
​	•	Our Compensation Committee grants stock options and time-based and performance-based restricted shares to our NEOs with a grant date fair value determined based on our Compensation Committee's general understanding of current competitive pay practices, our CEO's recommendation (except in the case of his own awards), recommendations from our compensation consultant, internal pay equity, evaluation of each NEO's performance, and other factors our Compensation Committee deems appropriate.	

28

Table of Contents

 	 	 	 	
​	•	Long-term incentive awards are allocated, based on grant date fair value, as follows (with vesting terms that generally extend up to four years):	 	
​	​	     o   One-third stock options	 	
​	​	     o   One-third time-based restricted shares	 	
​	​	     o   One-third performance-based restricted shares	 	
​	​	Our Compensation Committee believes this mix provides NEOs with a balanced retention and performance opportunity and serves to closely align our NEOs' long-term objectives with those of our stockholders.	 	
​	•	Each performance-based restricted share award has a target number of shares to be earned following completion of a three-year performance period based on the achievement of certain pre-established Company performance criteria. These performance-based restricted shares will be earned and vest upon the completion of the three-year fiscal period if the relevant performance criteria are achieved.	 	
​	Process:	 	
​	•	In the first fiscal quarter, our CEO recommends grant date fair values of awards for executives other than himself.	 	
​	•	Our Compensation Committee reviews proposed awards with input from its compensation consultant.	 	
​	•	Our Compensation Committee approves the number of time-based shares underlying stock options and the target number of time-based and performance-based restricted shares granted to our NEOs.	 	
​	•	Our Compensation Committee reports equity award determinations to our full Board.	 	
Severance and Change in Control Benefits	Objectives:	 	
 	Severance and change in control benefits are included in each NEO's employment agreement in order to promote stability and continuity of our senior management team in the event of a potential change in control and/or any involuntary termination. Our Compensation Committee believes these provisions help to align our NEOs' interests appropriately with those of our stockholders in these scenarios.	 	
 	Key Features:	 	
 	•	Events triggering payment require a termination of our NEOs' employment by our Company without cause or by the executive for good reason. Executives are entitled to enhanced benefits if the qualifying termination occurs during a specified period following a change in control (i.e., double-trigger).	 	
 	•	Change in Control benefits do not include excise tax gross-ups.	 	
 	•	Our Compensation Committee has determined these termination-related benefits are appropriate to preserve productivity and encourage retention in the face of potentially disruptive circumstances.	 	
 	•	Each NEO will only be eligible to receive severance payments if he or she signs a general release of claims following an eligible termination.

Chief Executive Officer Compensation
As our Chairman and CEO in 2016, Mr. Waldis' responsibilities were much greater than those of our other NEOs, as he was informed and involved in a detailed manner with each department's progress toward our shared Company goals. As a result, his total base salary and his total compensation opportunity are greater than our other NEOs. In addition, his equity holding requirements under our Executive Stock Ownership Guidelines require that he hold equity with a value at least equal to five times his base salary as opposed to three times for our other NEOs. As of December 31, 2016 and April 6, 2017, Mr. Waldis exceeded the minimum holding requirements under these stock ownership guidelines. In our industry, the CEO must be deeply aware of his or her company's strengths and obstacles and he or she must have sharp strategic vision for the company's future, while maintaining the ability to adapt to changing circumstances and prospects quickly and thoughtfully. The successful progress of our research and development programs and success of our customer engagements drove value to our financial performance and our stockholders, and we believe Mr. Waldis' direction in the decisions and actions that drove this progress merited the compensation that he received.
Pay Mix
In keeping with our results-driven culture, our Compensation Committee expects our NEOs to deliver superior performance in a sustained fashion and believes that a substantial portion of their overall compensation should be at-risk and tied to our short-term and long-term performance. As shown below, 77% of our CEO's targeted compensation and 64% of the average targeted compensation of our other NEOs for 2016 was tied to long-term, equity-based incentives.

2016 Compensation Decisions
In determining the criteria for our NEOs' incentive compensation, our Compensation Committee considers a variety of factors, including alignment of our NEOs' compensation with our stockholders' returns, and from time to time may adjust these factors or performance metrics based on our Company's fundamental transactions. On the corporate level, our Compensation Committee selected non-GAAP revenue and non-GAAP EBITDA, two metrics that the Committee believes appropriately values our Company on both a short- and long-term basis and are targeted to emphasize strong growth on gross revenue while also managing our earnings per share. Based on feedback received as part of our stockholder outreach program, these are also two of the key metrics a majority of our stockholders use in their valuation of our Company. As a result, our NEOs are focused on growing non-GAAP revenue and non-GAAP EBITDA, which we believe is aligned with our stockholders' perspective on our Company's ability to grow and succeed on the short- and long-term.
Base Salary
Base salaries for our NEOs are reviewed and may be adjusted annually. Base salary may also be adjusted during the year upon promotion or based on internal equity or external market conditions. Our Compensation Committee makes these decisions after reviewing the recommendation of our CEO (except as it concerns his own salary) and our Executive Vice President of Human Resources, and consulting with our compensation consultant. Based on this review, the Compensation Committee provided cost of living increases of 3% to Messrs. Waldis and Garcia in 2016. As each of Ms. Rosenberger's and Mr. Prague's base salary was below the competitive range of similarly situated roles at our peer group companies, and based on other publicly-available information, the Compensation Committee approved increases for them of 9% and 6%, respectively, in 2016. In addition, as a result of his promotion to Executive Vice President, Sales in late 2015, Mr. Putnam received a base salary increase of 36% in 2016 based on our Compensation Committee's review of the base salaries of similarly situated employees at our peer group companies and other publicly-available information.
The table below sets forth each of our NEOs' 2016 base salary compared to his or her respective 2015 base salary:

 	2015	2016	
Name	Base Salary	Base Salary	
Stephen G. Waldis	$591,165	$608,900	
Karen L. Rosenberger	$330,000	$360,000	
Robert E. Garcia	$437,091	$450,204	
Christopher S. Putnam	$250,000	$340,000	
Ronald J. Prague	$297,901	$315,000	
2016 Annual Cash Incentive Bonus Compensation
Our Annual Cash Incentive Bonus Compensation Program promotes our pay-for-performance philosophy by providing all executives and other management-level corporate employees with direct financial incentives in the form of annual cash awards for achieving Company, business and individual performance goals.
Target Percentage
Our Compensation Committee sets each NEO's individual target cash incentive amount (expressed as a percentage of base salary) based on its general understanding of competitive pay practices, our CEO's recommendation (except with respect to his own target) and other factors it deems appropriate. Based on its review of these factors, in February 2016, our Compensation Committee kept the target bonus percentage of each of our NEOs (other than Mr. Putnam) at the same level as in 2015. Since Mr. Putnam is responsible for worldwide sales, our Compensation Committee did not believe it appropriate to tie his target cash incentive bonus to achievement of corporate objectives. His cash incentive bonus was instead determined 100% based on achievement of individual objectives. For 2016, his target bonus was equal to 120% of his base salary and his maximum bonus was equal to 140% of his base salary. Our Compensation Committee determined that this was appropriate for Mr. Putnam based, among other things, on the target and maximum bonuses of our other executive officers, his expected senior role at our Company and the Compensation Committee's general understanding of competitive pay practices.

Table of Contents

The target cash incentive and maximum bonus percentages for each of our NEOs for 2016 were as follows:

Name	 Target Incentive
Bonus Percentage	 Maximum
Bonus Percentage	
Stephen G. Waldis	110% of base salary	192.5% of base salary	
Karen L. Rosenberger	60% of base salary	105% of base salary	
Robert E. Garcia	80% of base salary	140% of base salary	
Christopher S. Putnam	120% of base salary	140% of base salary	
Ronald J. Prague	60% of base salary	105% of base salary	
For 2016, the cash incentive bonus for each of our NEOs (other than Mr. Putnam) was determined as follows: (i) 90% based on a corporate component and (ii) 10% based on a discretionary individual performance component. Mr. Putnam's cash incentive bonus was based 100% on his achievement of certain individual objectives.
2016 Corporate Component
Our Compensation Committee established (i) non-GAAP revenue and (ii) non-GAAP EBITDA as the corporate components of our 2016 annual cash incentive bonus program, with each of the components weighted at 50% of the overall corporate component. We utilize these non-GAAP financial measures internally in analyzing our financial results and evaluating our ongoing operational performance because they exclude certain non-cash adjustments required under GAAP. These metrics were also selected because they are two of the key performance metrics shareholders use in evaluating our Company. Our 2016 internal annual operating plan was developed by management and presented by Mr. Waldis, as CEO, and Ms. Rosenberger, as CFO, to our Board for its review and approval. The target performance levels are intended to align with our annual internal operating plan to motivate performance in a manner we believe will increase stockholder value.
Although the expectations shared in our public guidance reflected strong growth in both non-GAAP revenue and non-GAAP EBITDA, our Compensation Committee established the 2016 corporate targets that exceeded our public guidance in order to motivate management to stretch for outstanding performance. In calculating both non-GAAP revenue and non-GAAP EBITDA, we add back stock-based compensation expense, the deferred revenue write-down associated with acquisitions, acquisition-related costs, restructuring charges, changes in the contingent consideration obligation, deferred compensation expense related to earn-outs and amortization of intangibles associated with acquisitions.
Each of the corporate components was assigned a "threshold" level, which is the minimum achievement level that must be satisfied to receive a portion of the applicable bonus amounts, and a "maximum" level, which, if achieved or exceeded, would result in our NEOs receiving 175% of the target amount attributed to that component.
The corporate component of the 2016 cash incentive compensation plan is set forth below:

Corporate Component	Weighting	 Threshold
25% payout	 Target
100% payout	 Maximum
175% payout	
Non-GAAP Revenue*	50	%	637,000,000	
 	695,000,000	
 	750,000,000	
 	
Non-GAAP EBITDA*	50	%	197,500,000	
 	230,100,000	
 	255,000,000	
 	
* These financial measures are non-GAAP measures and should not be reviewed in isolation or as substitutes for our financial results as reported in accordance with GAAP. Please see Appendix A for an explanation of these non-GAAP financial measures to the applicable GAAP financial measures.
During 2016, our Company strategy changed to focus on our enterprise and Cloud businesses, and de-emphasize our activation business. As a result of this change in strategy we (i) divested a significant portion of our activation business to Sequential Technology International, LLC, (ii) entered in to an agreement to acquire Intralinks, which closed in January 2017, and (iii) did not pursue certain non-strategic opportunities for its legacy activation business.  Accordingly, for purposes of determining attainment of the 2016 corporate component objectives, our Compensation Committee determined it was appropriate to adjust our actual performance to reflect these developments that were not anticipated when the performance goals were set. In consultation with Deloitte, our compensation consultant and after reviewing several alternative approaches, each of which rendered similar results, our Compensation Committee, based on Deloitte's recommended approach, in order to reflect a full year of performance, determined actual 2016 performance by taking our actual 2016 non-GAAP revenue and non-GAAP EBITDA from continuing operations and adding to that (i) non-GAAP revenue and non-GAAP EBITDA related to discontinued operations, (ii) forecasted non-

GAAP revenue and non-GAAP EBITDA for the divested business from the date of the transaction in the beginning of December 2016 through the end of the calendar year and (iii) activation-related revenue opportunities that were not pursued as a result of our Company's shift in business strategy relating to our anticipated Intralinks acquisition.

As a result, using the above determinations, we determined an Adjusted Non-GAAP revenue measure of $698.4 million (comprised of $490.2 million from continuing operations, $145.6 million from discontinued operations and $62.6 million from forecasted non-GAAP revenue for the divested business from the date of the transaction in the beginning of December 2016 through the end of the calendar year and the strategic opportunities not pursued, as discussed above), representing 20% growth from 2015, slightly above target. Using the same adjustments, we determined an Adjusted Non-GAAP EBITDA measure of $237.2 million (comprised of $136.5 million from continuing operations, $46.2 million from discontinued operations and $54.6 million from forecasted non-GAAP EBITDA for the divested business from the date of the transaction in the beginning of December 2016 through the end of the calendar year and the strategic opportunities not pursued, as discussed above), representing a 14% growth from 2015, also slightly above target. The level of plan payout that was applied to each of the corporate performance components of the 2016 cash incentive compensation program, which payout percentages were then applied to cash incentive compensation payments to our NEOs, is as set forth in the following table:

Corporate Component	Weighting	Achievement	Plan Payout	
Adjusted Non-GAAP Revenue	50	%	698,400,000	
 	105	%	
Adjusted Non-GAAP EBITDA	50	%	237,200,000	
 	121	%	
2016 Individual Component
In 2016, the individual component of each NEO's annual cash incentive compensation was based upon our Compensation Committee's subjective assessment of his or her individual performance.
Based on the committee's assessment and Mr. Waldis' recommendations (other than with respect to his own incentive compensation), our Compensation Committee approved the following as the individual component of their annual cash incentive compensation:
 	 	
•	Mr. Waldis received 100% of target due to his integral role in leading our Company during the year through our strong growth, spearheading the Openwave and Intralinks acquisitions and leading our overall strategy.	
 	 	
•	Ms. Rosenberger received 100% of target due to her efforts in helping us achieve our continued strong financial performance and arranging and negotiating the financing required for the Intralinks Transaction.	
 	 	
•	Mr. Garcia received 100% of target due to his strong performance in ensuring our operations continued to perform well and, in particular, controlling costs throughout the organization.	
 	 	
•	Mr. Putnam received 100% of target due to his strong performance in leading our worldwide sales effort and leading the negotiations of several key customer deals.	
 	 	
•	Mr. Prague received 100% of target due to his strong performance in leading the negotiations of the Openwave and Intralinks acquisitions, continuing our strong patent program and assisting in the negotiation and closing of several key customer deals.	
Based on the results of the corporate and individual performance components of the annual cash incentive plan, our NEOs were awarded the following amounts under the 2016 cash incentive bonus plan:

2016 Long-Term Equity Incentive Compensation Plan
Our Compensation Committee awards time-based restricted shares, time-based stock options and performance-based restricted shares to our NEOs as the long-term equity incentive component of their compensation, targeting an annual mix of one-third for each of these types of equity awards (based on grant date fair value). The number of shares underlying stock options, the target number of performance-based restricted shares and the number of time-based restricted shares granted to our NEOs is based on our Compensation Committee's general understanding of competitive pay practices, our CEO's recommendation (except with respect to his own awards) and other factors that our Compensation Committee deems appropriate.
Time-Based Restricted Stock and Stock Options
In February 2016, our Compensation Committee granted time-based restricted stock, and time-based options to purchase shares of our Common Stock to our NEOs. The time-based restricted shares vest one-third on each of the first, second and third anniversary of their grant date and the stock options vest one-fourth on the first anniversary of their grant date and in equal monthly installments thereafter over the next thirty-six months. The time-based vesting helps tie our NEOs' variable realizable compensation to our performance and further align their interests with those of our stockholders. See " Description of Awards Granted in 2016 ," below. The number of shares of time-based restricted stock awarded and number of shares subject to the options granted were:

Name	 	 Number of Time-Based
Shares of Restricted Stock	 	 Number of Shares
Subject to Options	
Stephen G. Waldis	 	52,951	 	133,043	
Karen L. Rosenberger	 	12,915	 	32,449	
Robert E. Garcia	 	32,287	 	81,124	
Christopher S. Putnam	 	9,944	 	24,986	
Ronald J. Prague	 	10,978	 	27,582	

Performance-Based Restricted Shares
Transition Performance Shares
In 2015, we transitioned to our new executive long-term incentive compensation program, which includes performance-based restricted shares that are earned based on achievement of three-year targets. As part of this transition, our Compensation Committee recognized that there would be a gap in the equity provided to our NEOs for a two-year transition period during which they would not be eligible to earn any performance-based restricted shares. To address this gap and to provide a retention incentive during the phase-in of the new program, in February 2015, our Compensation Committee approved a one-time grant of performance-based restricted shares (the " 2015-2016 Performance Shares "). One-third of these restricted shares was earned in February 2016 based on our financial results in 2015. Two-third of these restricted shares was to be earned based on our financial results in 2016. The performance metrics applicable to the 2015-2016 Performance Shares for 2016 were:
 	 	
•	60% based on non-GAAP revenue growth of our Company;	
 	 	
•	30% based on our non-GAAP EBITDA; and	
 	 	
•	10% based on non-GAAP Cloud revenue.	

Each of the components was separately assigned a "threshold" level, which established the minimum achievement necessary to be satisfied to receive any portion of the applicable bonus amounts, and a "maximum" level, which, if achieved or exceeded, would result in 200% of the target restricted shares being earned with respect to such component as described below.

As Mr. Putnam was not an executive officer in 2015, he did not receive any 2015-2016 Performance Shares.
In February 2015, our Compensation Committee approved the following threshold, target and maximum performance goals for 2016 for the 2015-2016 Performance Shares and, therefore, these performance goals were different than those approved by our Compensation Committee for the corporate component of our NEOs' annual cash incentive cash bonus:

 	Corporate Component	 	 Threshold
50% payout	 	 Target
100% payout	 	 Maximum
200% payout	 	Weighting	
 	Non-GAAP Revenue*	 	$667,100,000	 	$696,100,000	 	$725,100,000	 	60%	
 	Non-GAAP EBITDA as % of Revenue*	 	25%	 	35%	 	45%	 	30%	
 	Non-GAAP Cloud Revenue*	 	$388,400,000	 	$412,200,000	 	$436,000,000	 	10%	
In 2016, using the same calculations as discussed under"2016 Corporate Component - 2016 Annual Cash Incentive Bonus ":
 	 	
•	our Adjusted Non-GAAP revenue was $698.4 million, representing 20% growth from 2015, and above the target attainment, resulting in a 108% payout with respect to this component;	
 	 	
•	our 2016 Adjusted Non-GAAP EBITDA was $237.2 million, or 34% of revenue, representing 14% growth from 2015, and slightly below the target attainment, resulting in a 95% payout with respect to this component; and	
 	 	
•	our 2016 non-GAAP Cloud revenue was $403.4 million, representing 27% growth from 2015, and slightly below the target threshold, resulting in a 81% payout with respect to this component.

 	Non-GAAP Cloud Revenue*	 	$403,381,000	 	81%	 	10%	
* This financial measure is a non-GAAP measures and should not be reviewed in isolation or as substitutes for our financial results as reported in accordance with GAAP. Please see  Appendix A  for an explanation and reconciliation of these non-GAAP financial measures to the applicable GAAP financial measures .

As a result, our NEOs earned 101% of the target number of 2015-2016 Performance Shares based on the Company's 2016 financial performance. All of these 2015-2016 Performance Shares vested upon issuance. The actual number of 2015-2016 Performance Shares awarded based on our 2016 performance is set forth below:

Name	 	Performance
Shares Awarded	
Stephen G. Waldis	 	17,509

2016-2018 Performance Shares
In 2016, our Compensation Committee granted our NEOs the 2016-2018 Performance Shares. The actual number of 2016-2018 Performance Shares earned will depend on our Company's financial performance over the three-year period commencing on January 1, 2016 based on the following criteria: 60% based on non-GAAP revenue, 30% based on non-GAAP EBITDA and 10% based on the non-GAAP revenue from our Enterprise business. Due to our Company's determination in late 2015 to target certain of our products and services to the Enterprise market, our Compensation Committee believed that growth in this business was appropriate to use for our Company's strategic metric. The specific target values for the 2016-2018 Performance Shares were set using aggressive three-year growth targets tied to key corporate financial metrics. However, the targets that were set for the later years of the 2016-2018 plan, which were determined in 2016, were not publicly disclosed at the time of grant and will not be disclosed in this Proxy Statement due to the proprietary nature and competitive sensitivity of that information. The performance targets and achieved results will be fully disclosed after completion of the performance period.
The method used to calculate the 2016-2018 Performance Shares earned will be based on actual performance compared to our Company's targets for the 2016-2018 Performance Shares, as shown below, using straight-line interpolation between points. The determination of what number of shares (if any) have been earned will be made in January 2019 and any earned shares will vest upon issuance. Our NEOs were awarded 2016-2018 Performance Shares that provided the opportunity to earn the following restricted shares based on the performance of our business during the three-year period 2016 - 2018:

Employment Agreements, Other Benefits and Perquisites
Effective January 1, 2015, we entered into three-year employment agreements with each of our NEOs (other than Mr. Putnam) that expire on December 31, 2017. Upon his promotion to Executive Vice President, Sales in January 2016, we entered into an employment agreement with Mr. Putnam that also expires on December 31, 2017. Each of these employment agreements provides for severance payments and benefits upon an involuntary termination of employment and provides for enhanced benefits in the case of involuntary termination following a change in control, which is designed to promote stability and continuity of our senior management. For a description of the terms of the employment agreements, please see " Employment Agreements " below in this Proxy Statement.
Our NEOs are eligible to participate in all of our employee benefit plans (other than our employee stock purchase plan), such as medical, dental, vision, group life and disability insurance and our 401(k) plan, in each case, on the same basis as our other employees. In 2016, we leased an automobile (and paid applicable insurance and gas) for Mr. Waldis and Ms. Rosenberger and provided a car allowance to Mr. Garcia, each to be used primarily for business purposes. There were no other special benefits or perquisites provided to any NEO in 2016.

Financial Restatement, Recoupment and Related Policies
We have a comprehensive Ethics and Business Code of Conduct Policy and ensure that our employees comply with this policy. In accordance with this policy, we investigate all reported instances of questionable or unethical behavior, and where improper behavior is found to have occurred, we take appropriate remedial action up to and including termination. If the results of an investigation establish that one of our employees, officers or directors has committed fraud or engaged in some other improper act that has the result of causing our financial statements for any period to be restated or that otherwise adversely affects those financial statements, we will take immediate and appropriate disciplinary action against the individual, including but not limited to termination. In addition, we intend to pursue whatever legal remedies are available to prosecute the individual to the fullest extent of the law and we intend to seek to clawback or recoup any amounts he or she inappropriately received as a result of the improper action or inaction, including but not limited to any annual or long-term incentives that he or she received but would not have received had such act not been taken.
Executive Officer Stock Ownership Guidelines
We have instituted stock ownership guidelines for our executive officers with the purpose of ensuring they maintain a meaningful equity stake in our Company to further align their interests with those of our stockholders. Each executive officer who is also subject to Section 16 of the Exchange Act or who directly reports to our CEO (which includes all of our NEOs) is required to own, as of the later of January 1, 2020 or five years from the date on which the individual first began reporting to our CEO or first became a Section 16 officer, a number of vested shares of our Common Stock having a value at least equal to (a) in the case of our CEO, five times his then current base salary; (b) for our President and Chief Operating Officer, Chief Financial Officer, General Counsel or the General Manager of any of our divisions, three times that individual's then current base salary; and (c) for other executive officers subject to this policy, one and one-half times the individual's then current base salary. If an executive officer is not compliant at the end of his or her phase-in period, our Compensation Committee may reduce future equity grants to that individual until he or she becomes compliant. Based on share holdings on December 31, 2016, each of our NEOs exceeded his or her applicable minimum holding requirements on that date.

Tax Matters
Section 162(m) of the Internal Revenue Code places a $1,000,000 limit on the amount of compensation that we may deduct in any one year with respect to our CEO and our three other most highly paid NEOs (other than our Chief Financial Officer). To maintain flexibility in compensating NEOs in a manner designed to promote varying corporate goals, our Compensation Committee may, in its judgment, authorize compensation payments that are not deductible when it believes that those payments are appropriate, including when endeavoring to attract and retain highly-qualified executive officers.
Recent Developments
As disclosed on the Current Report on Form 8-K filed with the SEC on January 19, 2017, on January 18, 2017, in connection with the anticipated closing of the Intralinks Transaction, our Board appointed Ronald W. Hovsepian as the Company's Chief Executive Officer and appointed Mr. Hovsepian as a Class III member of our Board, in each case effective upon the closing of the Intralinks Transaction, which occurred on January 19, 2017 .  Effective at the same time, Mr. Waldis resigned as our Chief Executive Officer and was appointed as the Executive Chairman of the Board.

As disclosed on the Current Report on Form 8-K filed with the SEC on February 14, 2017, Karen L. Rosenberger resigned as our Chief Financial Officer, effective February 27, 2017, and her employment with us terminated as of April 1, 2017 (the “ Termination Date ”). In connection with her departure, our Board approved a separation and release agreement with Ms. Rosenberger (the “ Release Agreement ”). Under the Release Agreement, Ms. Rosenberger’s current health coverage will continue until April 30, 2017 and she is eligible to continue her health care coverage beyond that date through COBRA. In exchange for a broad release in favor of the Company, the Release Agreement provides for the following payments to Mrs. Rosenberger: (i) severance in the amount of $1,203,681 (less all applicable withholdings and deductions); (ii) the gross amount of $21,814, which is intended to cover the employer portion of any COBRA payments for a period of eighteen months following the Termination Date; (iii) a transition payment of $200,000 (less all applicable withholdings and deductions), provided Ms. Rosenberger actively participated in providing transition assistance to the Company’s executive team at an acceptable level through the Termination Date; and (iv) an amount of $580,000 (less all applicable withholdings and deductions), provided Ms. Rosenberger, on or before the Termination Date, signs a standard consulting services agreement with the Company to provide services on at least an as-needed basis with a term of no less than three months. As Ms. Rosenberger complied with the above obligations, we paid her the above amounts as part of her severance arrangement. All of Ms. Rosenberger's unvested equity terminated as of the Termination Date.

As disclosed on the Current Report on Form 8-K filed with the SEC on March 2, 2017, effective as of February 27, 2017, our Board appointed John W. Frederick to serve as the Company’s Chief Financial Officer and Treasurer. Pursuant to the terms of his employment agreement with our Company, Mr. Frederick will receive an annual base salary of $425,000 and be eligible to receive an annual performance bonus, with a target amount equal to 80% of his annual base salary, based upon the achievement of certain Company and individual objectives as determined by our Compensation Committee. Mr. Frederick also participates in the Company’s 2017-2019 Executive Long Term Incentive Plan ,  with a target award valued at $1.9 million. This award consists of 50% time-based restricted shares and 50% performance-based restricted shares. One-third of the time-based restricted shares will vest each year and the performance-based award will vest based on the determination by our Board or our Compensation Committee of the achievement of certain pre-determined performance metrics. In addition to these equity awards, the Company also granted Mr. Frederick restricted shares with a grant date fair value of $450,000, 25% of which will vest on the one-year anniversary of the vesting commencement date and 1/12th of the remaining shares will vest on each quarterly anniversary thereafter, subject to Mr. Frederick’s continued service to the Company.

As disclosed on the Current Report on Form 8-K filed with the SEC on March 30, 2017 (as amended on April 3, 2017), our Board (i) approved a base salary for Ronald W. Hovsepian, our Chief Executive Officer, of $609,000 and a target bonus percentage equal to 110% of his base salary; (ii) revised the compensation of Stephen G. Waldis in connection with his appointment as our Executive Chairman, by reducing his base salary to $500,000 and reducing his target bonus percentage to 100% of his base salary to reflect his change in role from Chief Executive Officer; and (iii) increased the base salary of Robert E. Garcia from $450,200 to $475,000 (with no change to his target bonus percentage, which remains at 80% of his base salary).

(1)	Each of our NEOs was granted a non-equity incentive plan award pursuant to our 2016 annual incentive bonus compensation plan. The amounts shown in the "Threshold" column reflect the cash payment that would have been awarded under our 2016 annual incentive bonus plan if we had achieved the threshold payout level for a single corporate objective with the lowest weight. The amounts shown in the "Target" column reflect the target payment level under our 2016 annual incentive bonus plan if we had achieved all of the objectives previously approved by our Compensation Committee at target levels. The amounts shown in the "Maximum" column reflect the maximum payouts under our 2016 annual incentive bonus compensation plan if we had achieved all of the objectives previously approved by our Compensation Committee at or above the maximum level. The corporate and business components of our 2016 annual incentive bonus compensation plan are discussed in greater detail in " Compensation Discussion and Analysis " above. The actual amounts paid to each NEO are shown in the Summary Compensation Table above. The table does not include the individual discretionary component portion of the NEOs' aggregate targeted annual cash incentive bonus amount.	
 	 	
(2)	Reflects 2016-2018 Performance Shares as described in greater detail in "Compensation Discussion and Analysis" above. The amounts shown in the "threshold" column reflect the 2016-2018 Performance Shares that will be earned if certain minimum financial goals are achieved. The amounts shown in the "target" column reflect the number of 2016-2018 Performance Shares that will be earned if all of the 2016-2018 financial goals are achieved at target levels. The amounts shown in the "maximum" column reflect the maximum number of 2016-2018 Performance Shares that can be earned if all of the 2016-2018 financial goals are achieved at or above maximum levels .	
 	 	
(3)	One-third of the restricted shares vested on February 19, 2017 and one-third of the restricted shares vest on each of February 19, 2018 and 2019, provided that the recipient remains continuously employed by our Company through each such date except that with, respect to Mr. Prague's January 27, 2016 grant of restricted shares, one-half of the shares vested on January 27, 2017 and the remaining one-half will vest on January 27, 2018, subject to Mr. Prague's continued service to the Company.

(4)	The options vest over four years from the vesting start date of February 19, 2016, with 25% of the shares vesting after the completion of the first year of service to the Company and the remaining shares vesting in equal monthly installments over an additional 36 months of continuous service to the Company. As a result, the option will be fully exercisable on February 19, 2020.	
 	 	
(5)	The amount in this column reflects the grant date fair value, computed in accordance with FASB ASC Topic No. 718, of stock awards and options granted to our NEOs. See Footnote 2 to the Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 for a discussion of our assumptions in estimating the fair value of our stock and option awards.

The amount shown reflects the maximum award if all of the associated performance metrics were achieved for the fiscal year ended December 31, 2016. The actual number of shares earned was determined in January 2017 and is shown in the table below. These shares became fully vested when that determination was made.

(25) Each NEO employed by our Company on February 19, 2015 was awarded a new business performance-based restricted share award that is earned if our Company establishes a new line of business with a meaningful revenue rate by the end of 2017. The amount shown reflects the maximum award if the performance metrics were achieved. The actual number of shares earned will be determined in January 2018, at which time the shares will be issued and will be fully vested.

______________________________
(1)For option awards, value realized on exercise is based on the fair market value of our Common Stock on the exercise date less the exercise price. For stock awards, value realized on vesting is based on the fair market value of our Common Stock on the vesting date. In neither case do the amounts set forth above necessarily reflect proceeds actually received by the NEO. Our NEOs will only realize value on these awards when the underlying shares are sold, which value may differ from the value shown in the table above as it is dependent on the price at which such shares of Common Stock are actually sold.
Employment Agreements
Effective January 1, 2015, we entered into three-year employment agreements with each of our NEOs (other than Mr. Putnam) that expire on December 31, 2017. Upon his promotion to Executive Vice President, Sales, effective January 1, 2016, we entered into an employment agreement with Mr. Putnam that also expires on December 31, 2017. Each of these employment agreements provides for severance benefits designed to promote stability and continuity of our senior management. Our Compensation Committee believes these agreements enhance our ability to retain the services of our NEOs, including in the event of a threatened or actual change in control, appropriately balancing our interests with those of our stockholders. In addition, our Compensation Committee believes that the events triggering payment are fair hurdles for providing this protection.
As of December 31, 2016, each of our NEOs was eligible to receive severance under his or her respective employment agreement if he or she is subject to an involuntary termination, contingent on the NEO's signing and not revoking a general release of all claims against the Company. Our severance benefits are provided as a temporary source of income in the event of an NEO's involuntary termination of employment.
The employment agreements provide that if prior to, or after 24 months following, the occurrence of a “change in control” (as defined in the employment agreements), any of our NEOs' employment is subject to an “involuntary termination” (as defined in the employment agreements), he or she shall be eligible to receive a lump-sum severance payment equal to (i) one and one-half times the sum of his or her base salary in effect at the time of termination, (ii) his or her average bonus received in the immediately preceding two years (or two times the sum of such base salary and average bonus with respect to Mr. Waldis) plus (iii) an amount equal to 24 times the monthly amount the Company was paying on behalf of the NEO and his or her eligible dependents with respect to the Company’s health insurance plans in which the NEO and his or her eligible dependents were participants as of the date of termination. The amount of these severance benefits shall be reduced by the amount of severance pay or pay in lieu of notice that the NEO receives from the Company under any applicable federal or state statute.
The employment agreements also provide that if an involuntary termination occurs within 24 months following a change in control, the NEOs shall be eligible to receive a lump sum severance payment equal to (i) two times his or her base salary in effect at the time (or 2.99 times such base salary with respect to Mr. Waldis), (ii) two times his or her average bonus received in the immediately preceding two years, plus (iii) an amount equal to 24 times the monthly amount the Company was paying on behalf of the NEO and his or her eligible dependents with respect to the Company’s health insurance plans in which the NEO and his or her eligible dependents were participants as of the date of termination. In addition, his or her outstanding options and restricted shares will vest and become exercisable in full as of the date of such involuntary termination. If an NEO dies, the NEO’s estate will receive an amount equal to his or her target cash

incentive bonus for the fiscal year in which such termination occurs, prorated based on the number of days of employment completed during that fiscal year.
If an NEO’s employment terminates due to “permanent disability” (as defined in the employment agreements), the NEO will be entitled to receive (i) an amount equal to his or her target cash incentive bonus for the fiscal year in which such termination occurs, prorated based on the number of days of employment completed during that fiscal year, plus (ii) a lump sum amount equal to 24 times the monthly amount the Company was paying on behalf of the NEO and his or her eligible dependents with respect to the Company’s health insurance plans in which the NEO and his or her eligible dependents were participants as of the date of termination.
In connection with her resignation as Executive Vice President and Chief Financial Officer on February 27, 2017, we entered into the Release Agreement with Ms. Rosenberger, which provides for certain severance payments and benefits for Ms. Rosenberger. See " Compensation Discussion and Analysis - Recent Developments " above for a description of the Release Agreement and the amounts payable to Ms. Rosenberger thereunder.

Estimated Payments and Benefits
The table below reflects the potential payments and benefits to which the NEOs would be entitled pursuant to their respective employment agreements. There are no agreements, arrangements or plans that entitle executive officers to severance, perquisites, or other enhanced benefits in connection with the termination of their employment other than the employment agreements. The amounts shown in the table below assume that each termination was effective as of December 31, 2016.

(1)	For purposes of valuing cash severance payments in the table above, we used each executive officer's base salary as of December 31, 2016. For purposes of calculating cash severance payments in the table above in the event of an involuntary termination (whether prior to, within 24 months following, or more than 24 months following, a change in control), we used each NEO’s average annual bonuses for 2014 and 2015 and, for purposes of calculating cash severance payments in the table above in the event of a termination due to permanent disability, we used the NEO’s target bonus as of December 31, 2016.

(2)	The value of option acceleration shown in the table above was calculated based on the assumption that the triggering event occurred on December 31, 2016. The value of the vesting acceleration was calculated by multiplying the number of unvested shares subject to each option by the excess of the closing price of our Common Stock on December 30, 2016, the last trading day of the year, over the exercise price of the option.	
 	 	
(3)	The value of restricted stock acceleration shown in the table above was calculated based on the assumption that the triggering event occurred on December 31, 2016. The value of the vesting acceleration was calculated by multiplying the number of unvested shares subject to each restricted stock grant by the closing price of our Common Stock on December 30, 2016, the last trading day of the year.	
 	 	
(4)	Based on each executive officer's base salary in effect and the number of each NEO's accrued but unused vacation days as of December 31, 2016.	
 	 	
(5)	Amounts reflect two times the current cost to us of the individual's health and welfare benefits per year.

Equity Security Ownership of Certain Beneficial Owners and Management
The following table sets forth information as of March 27, 2017 with respect to the beneficial ownership of our Common Stock by persons known to us to own beneficially more than 5% of our Common Stock, each of our directors, our current executive officers and all of our executive officers and directors as a group. We have no other class of equity securities outstanding.
As of March 27, 2017, 46,372,470 shares of our Common Stock were outstanding. The amounts and percentages of our Common Stock beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. The information does not necessarily indicate beneficial ownership for any other purposes. Under the SEC rules, a person is deemed to be a "beneficial owner" of a security if that person has or shares "voting power," which includes the power to vote or direct the voting of such security, or "investment power," which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Under these rules, more than one person may be deemed a beneficial owner of securities as to which such person has no economic interest. Except in cases where community property laws apply or as indicated in the footnotes to this table, we believe that each stockholder identified in the table possesses sole voting and investment power over the shares of our Common Stock shown as beneficially owned by the stockholder.

Certain Related Party Transactions
Transactions, arrangements or relationships in which we were, are or will be a participant and the amount involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest are subject to review, approval or ratification by our Board or a committee composed of members of our Board. Our Audit Committee has the principal responsibility for reviewing related person transactions pursuant to written policies and procedures adopted by our Board, subject to specified exceptions and other than those that involve compensation. In conformance with regulations of the SEC, these policies and procedures define related persons to include our executive officers, our directors and nominees to become a director of our Company, any person who is known to us to be the beneficial owner of more than 5% of any class of our voting securities, any immediate family member of, or person sharing the household with, any of the foregoing persons, and any firm, corporation or other entity in which any of the foregoing persons is employed, is a general partner or in which such person has a 5% or greater beneficial ownership interest. In accordance with our policies and procedures, related person transactions shall be consummated or shall continue only if approved or ratified by our Audit Committee or the disinterested members of our Board and only if the terms of the transaction are determined to be in, or not to be inconsistent with, the best interests of our Company and our stockholders. The approval of our Compensation Committee is required to approve any transaction that involves compensation to our directors and executive officers. This approval process does not apply to any transaction that is available to all of our employees generally.
During 2016, we engaged Meeker Sharkey as our insurance broker for our officers and directors, commercial liability and health benefits insurance. Thomas Sharkey, Jr., a principal of Meeker Sharkey, is the brother in law of James M. McCormick, a member of our Board. During 2016, we paid Meeker Sharkey $366,231. In addition to any value received by Mr. Sharkey, Jr. by virtue of his minority ownership interest in Meeker Sharkey, he received a commission from Meeker Sharkey in connection with our insurance policies. Our Audit Committee approved our engagement of Meeker Sharkey as our insurance broker as a related party transaction.
Other than as described above, there were no other transaction or series of similar transactions to which we were or are a party in which the amount involved exceeded or exceeds $120,000 and in which any of our directors, current executive officers, holders of more than 5% of any class of our voting securities, or any member of the immediate family of any of the foregoing persons, had or will have a direct or indirect material interest, other than compensation arrangements, which are described where required under " Executive Compensation " and " Director Compensation " above.
Section 16(a) Beneficial Ownership Reporting Compliance
We believe that, during the fiscal year ended December 31, 2016, all of our directors, executive officers subject to Section 16 of the Exchange Act and greater than 10% stockholders complied with all applicable Section 16(a) filing requirements. In making these statements, we have relied upon a review of the copies of Section 16(a) reports furnished to us and the written representations of our directors, NEOs and certain of our greater than 10% stockholders.
Other Matters
Our Board does not intend to bring any other business before the meeting, and so far as is known to the Board, no matters are to be brought before the meeting except as specified in the notice of the meeting. In addition to the scheduled items of business, the meeting may consider stockholder proposals that are timely and comply with the provisions of our amended and restated bylaws (including proposals omitted from the Proxy Statement and form of Proxy pursuant to the proxy rules of the SEC) and matters relating to the conduct of the meeting. As to any other business that may properly come before the meeting, it is intended that proxies will be voted in respect thereof in accordance with the judgment of the persons voting such proxies.

PROPOSAL 1
ELECTION OF DIRECTOR
Our Board currently consists of six directors divided into three classes with staggered three-year terms. Your proxy cannot be voted for a greater number of persons than the number of nominees named in this proxy statement. The director who is nominated for election to our Board this year, his age as of April 6, 2017, his position and office held with us and certain biographical information are set forth below. The director to be elected will hold office until the 2020 Annual Meeting of Stockholders and until his successor is elected, or until his death, resignation or removal. The nominee listed below is currently a director of our Company who was previously elected by the stockholders. It is our policy to encourage nominees for director to attend the Annual Meeting. All of our directors other than Mr. Moore attended our 2016 Annual Meeting of Stockholders.
Our directors are elected by a plurality of the votes cast at the Annual Meeting, meaning that the nominee receiving the most "For" votes (among votes properly cast in person or by proxy) will be elected. An instruction to "Withhold" authority to vote for a nominee will result in the nominee receiving fewer votes, but will not count as a vote against the nominee. Abstentions and "broker non-votes" (i.e., shares held by a broker or nominee that are represented at the meeting, but with respect to which the broker or nominee is not instructed to vote on a particular proposal and does not have discretionary voting power) will have no effect on the outcome of the election of a candidate for director. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the nominee named below. If the nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by our current Board, if any. The nominee for election has agreed to serve if elected. We have no reason to believe that the nominee will be unable to serve.
BOARD OF DIRECTOR COMPOSITION
The following table includes the name, age, position, class and term expiration year for each of our directors and is current as of the date of this Proxy Statement. Information about the number of shares of common stock beneficially owned by each director, whether held directly or indirectly, as of April 6, 2017, appears below under the heading “ Equity Security Ownership of Certain Beneficial Owners and Management ."

PROPOSAL 2
RATIFICATION OF THE APPOINTMENT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Audit Committee of our Board has appointed Ernst & Young LLP, independent registered public accounting firm, as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2017 and has further directed that management submit the appointment of the independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Ernst & Young LLP has audited the Company's financial statements since its formation in 2000. Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.
Neither the Company's amended and restated by-laws nor other governing documents or law require stockholder ratification of the appointment of Ernst & Young LLP as the Company's independent registered public accounting firm. However, the Board is submitting the appointment of Ernst & Young LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the appointment, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.
To ratify the selection by the Audit Committee of Ernst & Young LLP, as the independent registered public accounting firm of the Company for its fiscal year ended December 31, 2017, the Company must receive a "For" vote from the majority of all the outstanding shares that are present in person or represented by proxy and cast either affirmatively or negatively at the Annual Meeting. Abstentions and broker non-votes will not be counted "For" or "Against" the proposal and will have no effect on the proposal. Because this proposal is a non-routine matter, a broker or other nominee may generally vote and therefore no broker non-votes are expected to exist in connection with this proposal.
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM'S FEES
The following table represents aggregate fees billed to the Company for fiscal years ended December 31, 2016 and December 31, 2015 by Ernst & Young LLP, the Company's principal accountant. All services described below for 2015 and 2016 were approved by the Audit Committee.

 	 	 	Fiscal Year Ended	
 	 	 	2016	 	2015	
 	 	 	(In thousands)	
 	Audit Fees(1)	 	$	3,025

 	Audit Related Fees(2)	 	235	
 	 	2	
 	
 	Total Fees	 	$	3,260	
 	 	$	2,283	
 	
______________________________
 	 	
(1)	For professional services rendered for the audits of annual financial statements, including the audit of annual financial statements and audit of internal control over financial reporting for the years ended December 31, 2016 and 2015. The audit fees also include the review of quarterly financial statements included in the Company's quarterly reports on Form 10-Q, statutory audits of foreign subsidiaries and other regulatory filings or similar engagements.	
 	 	
(2)	Includes fees that are for assurance and related services other than those included in Audit Fees and primarily relate to due diligence services relating to an acquisition.	
PRE-APPROVAL POLICIES AND PROCEDURES
The Audit Committee's policy, subject to certain permitted exceptions for certain de minimis services, is to pre-approve all audit and permissible non-audit services rendered by Ernst & Young LLP, our independent registered public accounting firm. The Audit Committee can pre-approve specified services in defined categories of audit services, audit-related services and tax services up to specified amounts, as part of the Audit Committee's approval of the scope of the engagement of Ernst & Young LLP or on an individual case-by-case basis before Ernst & Young LLP is engaged to provide a service. The Audit Committee has determined that the rendering of the services other than audit services by Ernst & Young LLP is compatible with maintaining the principal accountant's independence. The independent registered public accounting firm and management are required to meet with the audit committee to review and discuss our annual and quarterly financial statements and related disclosures, as well as our critical accounting policies and practices. Additionally, the audit committee is responsible for reviewing the audit plan with the independent registered public accounting firm and members of management responsible for preparing our consolidated financial statements. All of the services of Ernst & Young LLP for 2015 and 2016 described above were pre-approved by the audit committee.

THE BOARD RECOMMENDS A VOTE "FOR" PROPOSAL 2

Table of Contents

PROPOSAL 3
ADVISORY VOTE ON EXECUTIVE COMPENSATION
As required by Section 14A of the Securities Exchange Act of 1934, as amended, we are requesting our stockholders to vote, on an advisory basis, on the compensation of our NEOs as described in the "Compensation of Executive Officers" section of this Proxy Statement. This proposal, commonly known as a "say-on-pay" proposal, gives our stockholders the opportunity to express their views on the compensation of our NEOs.
Compensation Program and Philosophy
Our executive compensation philosophy and programs are designed to attract, retain and motivate high-quality executives who possess the diverse skills and talents required to help us achieve our short and long-term financial and strategic goals. We believe that our executive compensation programs foster a performance-oriented culture that aligns our executives' interests with those of our stockholders over the long term. We believe that the compensation of our executives is both appropriate for and responsive to the goal of improving shareholder value. Specifically, we tie a significant portion of executive compensation to stockholder return in the form of at-risk or variable realizable compensation. The approval, on an advisory basis, of the compensation of the Company's NEOs as requires a "For" vote from the majority of all of the outstanding shares that are present in person or represented by proxy and cast affirmatively or negatively at the Annual Meeting. Abstentions and broker non-votes will not be counted "For" or "Against" this proposal and will have no effect on this proposal.
Compensation Discussion and Analysis
Stockholders are urged to read the "Compensation Discussion and Analysis" section of this Proxy Statement and the tables and narrative discussion that follow for detail about our executive compensation programs, including information about the fiscal year 2016 compensation of our NEOs.
Recommendation
For the above reasons, we are asking our stockholders to indicate their support for the compensation of our named executive officers as described in this Proxy Statement by voting in favor of the following resolution:
 	 	
RESOLVED:	That the stockholders approve, on an advisory non-binding basis, the compensation of the Company's named executive officers as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, related compensation tables, and the accompanying narrative disclosure set forth in the Proxy Statement relating to the Company's 2017 Annual Meeting of Stockholders.	
Even though this say-on-pay vote is advisory and therefore will not be binding, our Compensation Committee and our Board value the opinions of our stockholders. Accordingly, we expect to take into account the outcome of the vote when considering future executive compensation decisions.
THE BOARD RECOMMENDS A VOTE "FOR" PROPOSAL 3

Table of Contents

PROPOSAL 4
ADVISORY VOTE ON FREQUENCY OF FUTURE ADVISORY VOTES ON EXECUTIVE COMPENSATION
Section 14A of the Exchange Act provides that stockholders must be given the opportunity to vote, on a non-binding, advisory basis, for their preference as to how frequently we should seek future non-binding advisory votes to approve the compensation of our NEOs. This proposal, commonly known as a "say-on-pay frequency" proposal is designed to ask our stockholders to provide their input on how often we should conduct advisory "say-on-pay" votes in the future. We are required to conduct this vote at least every six years and we last conducted a "say-on-pay frequency" vote in the proxy statement for our 2011 annual meeting. At that time, we recommended the inclusion of a "say-on-pay" vote on an annual basis and 94.4% of the votes cast by our stockholders at our 2011 annual meeting of stockholders were cast in favor of an annual "say-on-pay" vote. We have conducted "say-on-pay" votes on an annual basis since that annual meeting.

This year, we are once again asking our stockholders to provide their input with regard to "say-on-pay frequency," asking whether the advisory "say-on-pay" vote should occur once every year, every two years or every three years. The advisory approval of the proposal regarding the frequency of future advisory votes on the compensation of the Company's NEOs requires a "For" vote for one of the three options presented: every "1 Year," every "2 Years" or every "3 Years." The option receiving the plurality of votes from the outstanding shares that are present in person or represented by proxy and cast affirmatively or negatively at the Annual Meeting will be the option deemed recommended by our stockholders. Abstentions and broker non-votes will not be counted "For" or "Against" this proposal and will have no effect on this proposal.

Our Board has determined that an annual advisory "say-on-pay" vote is the most appropriate alternative for Synchronoss. Our Board’s determination was influenced by the fact that the compensation of our NEOs is evaluated, adjusted and approved on an annual basis. As part of the annual review process, our Board concluded that stockholder sentiment should be a factor that is taken into consideration by the Board and the Compensation Committee in making decisions with respect to executive compensation.

By providing an advisory vote on executive compensation on an annual basis, our stockholders will be able to provide us with direct input on our compensation philosophy, policies and practices as disclosed in our proxy statement every year. We understand that our stockholders may have different views as to what is the best approach for Synchronoss and we look forward to hearing from our stockholders on this agenda item every year. Accordingly, our Board recommends that the advisory "say-on-pay" vote be held every year.

You may cast your vote on "say-on-pay frequency" by choosing the option of every 1 year, 2 years, or 3 years or you may abstain from voting on this proposal.
Recommendation
Accordingly, we are asking our stockholders to vote on the following resolution at the Annual Meeting:
 	 	
RESOLVED:	That the stockholders approve, on a non-binding, advisory basis, the submission by the Company of a non-binding, advisory say-on-pay resolution pursuant to Section 14A of the Exchange Act every:	
    
one year;

two years; or
    
three years.

The option of 1 year, 2 years or 3 years that receives the highest number of votes cast will be the frequency of the vote on the compensation of our NEOs that has deemed recommended by stockholders.

Even though your vote is advisory and therefore will not be binding on the Company, the Board and the Compensation Committee value the opinions of our stockholders and will consider our stockholders’ vote on this proposal. Nonetheless, the Board may decide that it is in the best interests of our stockholders and Synchronoss to hold an advisory vote on executive compensation more or less frequently than the option recommended by our stockholders.

Appendix A
Reconciliation of Non-GAAP Financial Information
(Unaudited – In thousands, except per share data)
Synchronoss Technologies, Inc. ("Synchronoss") has provided in this proxy statement selected financial information that has not been prepared in accordance with GAAP. This information includes non-GAAP revenues, gross profit, EBITDA and diluted earnings per share. Synchronoss uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to management and investors, as a supplement to GAAP measures, in evaluating Synchronoss' ongoing operational performance. Synchronoss believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends, and in comparing its financial results with other companies in Synchronoss' industry, many of which present similar non-GAAP financial measures to investors. The non-GAAP financial results add back the deferred revenue write-down associated with acquisitions, fair value stock- based compensation expense, acquisition-related costs, changes in the contingent consideration obligation, deferred compensation expense related to earn outs and amortization of intangibles associated with acquisitions.
Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures in the tables below.
