PROXY STATEMENT

FOR THE ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD MAY 9, 2012

We are providing this Proxy Statement to the stockholders of ADTRAN, Inc. in connection with the solicitation of proxies by our Board of Directors to be voted at the 2012 Annual Meeting of Stockholders and at any adjournments of that meeting. The Annual Meeting will be held at ADTRAN’s headquarters, 901 Explorer Boulevard, Huntsville, Alabama, on Wednesday, May 9, 2012, at 10:30 a.m., local time. The meeting will be held in the East Tower on the second floor. When used in this Proxy Statement, the terms “we,” “us,” “our” and “ADTRAN” refer to ADTRAN, Inc.

The approximate date on which this Proxy Statement and form of proxy card are first being sent or given to stockholders is March 30, 2012.

This Proxy Statement, the attached Notice of Annual Meeting and our 2011 Annual Report to Stockholders are available at www.proxyvote.com.

VOTING

General

The securities that can be voted at the Annual Meeting consist of our common stock, $0.01 par value per share, with each share entitling its owner to one vote on each matter submitted to the stockholders. The record date for determining the holders of common stock who are entitled to receive notice of and to vote at the Annual Meeting is March 12, 2012. On the record date, 63,896,853 shares of common stock were outstanding and eligible to be voted at the Annual Meeting.

Quorum and Vote Required

The presence, in person or by proxy, of a majority of the outstanding shares of our common stock is necessary to constitute a quorum at the Annual Meeting. In counting the votes to determine whether a quorum exists at the Annual Meeting, we will use the proposal receiving the greatest number of all votes “for” or “against” and abstentions, including instructions to withhold authority to vote.

In voting with regard to Proposal 1, the election of directors, stockholders may vote in favor of all nominees, withhold their votes as to all nominees or withhold their votes as to specific nominees. The vote required to approve Proposal 1 is governed by the Bylaws of the Company and is a majority of the votes cast by the holders of shares represented and entitled to vote at the Annual Meeting, provided a quorum is present. As a result, abstentions will be considered in determining whether a quorum is present and the number of votes required to obtain the necessary majority vote for the nominees and, therefore, will have the same legal effect as voting against the proposal.

In voting with regard to Proposal 2, an advisory vote to approve the Company’s executive compensation, stockholders may vote in favor of the proposal or against the proposal or may abstain from voting. As the vote is advisory only and not binding there is no required vote. In determining the results of the vote, however, abstentions will have the same legal effect as voting against the proposal.

In voting with regard to Proposal 3, the ratification of the appointment of the independent registered public accounting firm, stockholders may vote in favor of the proposal or against the proposal or may abstain from voting. The vote required to approve Proposal 3 is governed by Delaware law and is the affirmative vote of the holders of a majority of the shares represented and entitled to vote on the proposals at the Annual Meeting, provided a quorum is present. As a result, abstentions will be considered in determining whether a quorum is present and the number of votes required to obtain the necessary majority vote for each proposal and, therefore, will have the same legal effect as voting against the proposal.

Under the rules of the national stock exchanges that govern most domestic stock brokerage firms, member firms that hold shares in street name for beneficial owners may, to the extent that those beneficial owners do not furnish voting instructions with respect to any or all proposals submitted for stockholder action, vote in their discretion upon proposals that are considered “discretionary” proposals under the rules of the exchanges. These votes by brokers are considered as votes cast in determining the outcome of any discretionary proposal. We believe that Proposal 3 is discretionary. Member brokerage firms that have received no instructions from their clients as to “non-discretionary” proposals do not have discretion to vote on these proposals. If the brokerage firm returns a proxy card without voting on a non-discretionary proposal because it received no instructions, this is referred to as a “broker non-vote” on the proposal. “Broker non-votes” are considered in determining whether a quorum exists at the Annual Meeting, but “broker non-votes” are not considered as votes cast in determining the outcome of any proposal. We believe Proposals 1 and 2 are non-discretionary.

As of March 12, 2012, the record date for the Annual Meeting, our directors and executive officers beneficially owned or controlled approximately 1,227,505 shares of our common stock, constituting approximately 1.89% of the outstanding common stock. We believe that these holders will vote all of their shares of common stock in favor of each of the proposals.

Proxies

You should specify your choices with regard to each of the proposals (1) by telephone as directed on the enclosed proxy card, (2) over the Internet as directed on the enclosed proxy card, or (3) on the enclosed proxy card by signing, dating and returning it in the accompanying postage paid envelope. All properly executed proxy cards delivered by stockholders to ADTRAN in time to be voted at the Annual Meeting and not revoked will be voted at the Annual Meeting in accordance with the directions noted on the proxy card. In the absence of such instructions, the shares represented by a signed and dated proxy card will be voted “FOR” the election of all director nominees, “FOR” approval of a shareholder advisory vote on executive compensation and “FOR” the ratification of the appointment of the independent registered public accounting firm. If any other matters properly come before the Annual Meeting, the persons named as proxies will vote upon those matters according to their judgment.

Any stockholder delivering a proxy has the power to revoke it at any time before it is voted by:

•

giving written notice to James E. Matthews, Secretary of ADTRAN, at 901 Explorer Boulevard, Huntsville, Alabama 35806 (for overnight delivery) or at P.O. Box 140000, Huntsville, Alabama 35814-4000 (for mail delivery);

•

executing and delivering to Mr. Matthews a proxy card bearing a later date;

•

voting again prior to the time at which the telephone and Internet voting facilities close by following the procedures applicable to those methods of voting, as directed on the enclosed proxy card; or

•

voting in person at the Annual Meeting.

Please note, however, that under the rules of the national stock exchanges, any beneficial owner of our common stock whose shares are held in street name by a member brokerage firm may revoke his proxy and vote his shares in person at the Annual Meeting only in accordance with applicable rules and procedures of the exchanges, as employed by the beneficial owner’s brokerage firm.

In addition to soliciting proxies through the mail, we may solicit proxies through our directors, officers and employees in person and by telephone or facsimile. We have hired Georgeson Inc. to assist in the solicitation of proxies from stockholders at a fee of approximately $9,000 plus reasonable out-of-pocket expenses. We will pay all expenses incurred in connection with the solicitation of proxies. We may also request that brokerage firms, nominees, custodians and fiduciaries forward proxy materials to the beneficial owners of shares held of record by them. We will also reimburse such brokerage firms and other nominees for their reasonable expenses in forwarding proxy materials to beneficial owners of our common stock.

SHARE OWNERSHIP OF PRINCIPAL STOCKHOLDERS AND MANAGEMENT

The following table sets forth information regarding the beneficial ownership of our common stock as of March 12, 2012, by (1) each of our directors and our director emeritus, (2) each of our executive officers named in the Summary Compensation Table in this Proxy Statement and (3) all of our directors and executive officers as a group, based in each case on information furnished to us by these persons. We believe that each of the named individuals and each director and executive officer included in the group has sole voting and investment power with regard to the shares shown except as otherwise noted.

PROPOSAL 1 – ELECTION OF DIRECTORS

Nominees

The Board of Directors currently consists of seven members. In addition, James L. North, who was a Board member until his resignation in December 2002, currently serves as a director emeritus of ADTRAN. All members of the Board of Directors were elected at the 2011 Annual Meeting.

The Board of Directors has nominated Thomas R. Stanton, H. Fenwick Huss, Ross K. Ireland, William L. Marks, James E. Matthews, Balan Nair and Roy J. Nichols for election as directors at the 2012 Annual Meeting. If elected as a director at the Annual Meeting, each of the nominees would serve a one-year term expiring at the 2013 Annual Meeting of Stockholders and until his successor has been duly elected and qualified. There are no family relationships among the directors, director nominees or the executive officers.

Each of the nominees has consented to serve his term as a director if elected. If any of the nominees should be unavailable to serve for any reason (which is not anticipated), the Board of Directors may designate a substitute nominee or nominees (in which event the persons named on the enclosed proxy card will vote the shares represented by all valid proxies for the election of the substitute nominee or nominees), allow the vacancies to remain open until a suitable candidate or candidates are located, or by resolution provide for a lesser number of directors.

Our products and our success in our markets depend on our ability to stay abreast of and respond to developments in communications and information technologies. We have also grown profitably; in order to protect and enhance our growth and profitability it is important for us to understand the financial environments which impact us and the risks in those environments as well as the tools of corporate finance available to us to navigate and manage those risks. We also have a significant number of employees and numerous locations. In selecting directors we are concerned to have a diverse group of directors so that our board has an effective mix of technical, financial, operating and management experience in our directors. We have a long-standing policy of keeping our board relatively small. We also believe that our Board should be comprised predominantly of independent directors from diverse backgrounds external to the company but should nevertheless include the insight and judgment of our senior management; five of our seven directors are not employees.

The Board of Directors unanimously recommends that the stockholders vote “FOR” the proposal to elect Thomas R. Stanton, H. Fenwick Huss, Ross K. Ireland, William L. Marks, James E. Matthews, Balan Nair and Roy J. Nichols as directors for a one year term expiring at the 2013 Annual Meeting of Stockholders and until their successors have been duly elected and qualified.

CORPORATE GOVERNANCE

Board Structure – Independent Directors

The Nominating and Corporate Governance Committee and the Board of Directors have determined that Messrs. Ireland, Marks, Nair and Nichols and Dr. Huss do not have any relationships that would interfere with the exercise of independent judgment in carrying out their responsibilities as directors and are independent in accordance with Rule 4200(a)(15) of the NASDAQ Marketplace Rules. The incumbent independent directors also constitute all of the members of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee. Prior to each regularly scheduled Audit Committee meeting, these directors convene and hold a separate executive session as the independent directors of the Board. Mr. Nichols, our independent lead director, presides over these meetings, coordinates the activities of the independent directors and serves as liaison between the independent directors and our Chief Executive Officer and senior management. We believe this structure facilitates the development of a productive relationship with our Chief Executive Officer and ensures effective communication between our Chief Executive Officer and the independent directors.

Mr. Stanton is both our Chief Executive Officer and our Chairman; his predecessor, Mark Smith, one of our founders, also held both of these positions and we believe that having our Chief Executive Officer also holding the position of Chairman is important in underscoring his authority to our customers, our vendors and our employees and in our markets generally. We believe that this structure enhances our day to day operating effectiveness and does not undercut the benefits available to the Board of having separated these functions because we have established a lead director whose role is extensive and who in relationship to the other directors performs many of the functions that might otherwise be performed by a board chairman.

Meetings of the Board of Directors and its Committees

The Board of Directors conducts its business through meetings of the full Board and through committees of the Board, consisting of an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. During the fiscal year ended December 31, 2011, the Board of Directors held eleven meetings, the Audit Committee held eight meetings, the Compensation Committee held six meetings and the Nominating and Corporate Governance Committee held two meetings. No director attended less than 75% of the aggregate of meetings of the Board of Directors and of the committees of which he is a member. Six of the incumbent directors and director emeritus James North, attended the 2011 Annual Meeting of Stockholders on May 4, 2011.

Audit Committee

The Audit Committee is responsible for assisting the Board of Directors in fulfilling its oversight responsibilities with respect to: (1) the financial reports and other financial information provided by us to the public or any governmental body; (2) our compliance with legal and regulatory requirements; (3) our systems of internal controls regarding finance, accounting and legal compliance that have been established by management and the Board; (4) the qualifications and independence of our independent registered public accounting firm; (5) the performance of our internal audit function and the independent registered public accounting firm; and (6) our auditing, accounting and financial reporting processes generally. The Audit Committee has been established in accordance with Section 3(a)(58)(A) of the Exchange Act. In connection with its responsibilities, the Board has delegated to the Audit Committee the authority to select and hire our independent registered public accounting firm and determine their fees and retention terms. The Audit Committee operates under a charter approved by the Board. The charter is posted on our website at www.adtran.com. The Audit Committee is composed of H. Fenwick Huss, Ross K. Ireland, William L. Marks, Balan Nair and Roy J. Nichols, each of whom is independent under NASDAQ listing standards. Dr. Huss is the Chair of the Audit Committee. The Board has determined that Dr. Huss is an audit committee financial expert.

Compensation Committee

The Compensation Committee is responsible for setting the compensation of our Chief Executive Officer and assisting the Board in discharging its responsibilities regarding the compensation of our other executive officers. In addition, the Compensation Committee is responsible for administering our 2006 Employee Stock Incentive Plan, our 2010 Directors Stock Plan, our Variable Incentive Compensation Plan and our Deferred Compensation Plan. The Compensation Committee operates under a charter approved by the Board. The charter is posted on our website at www.adtran.com. The Compensation Committee is composed of H. Fenwick Huss, Ross K. Ireland, William L. Marks, Balan Nair and Roy J. Nichols, each of whom is independent under NASDAQ listing standards. Mr. Marks is the Chair of the Compensation Committee.

Compensation Committee Process

Under our Compensation Committee’s charter, the Committee has the power and duty to discharge our Board’s responsibilities related to compensation of our executive officers, within guidelines established by the Board. Generally, the Compensation Committee reviews and approves all compensation, including base salary, annual incentive awards and equity awards, for the Chief Executive Officer and our other officers. The Compensation Committee also makes recommendations to the Board regarding our incentive compensation plans and equity plans, and approves equity grants. The Committee has authority to review and approve annual performance goals and objectives for our Chief Executive Officer, to evaluate his performance and to set his compensation based on the evaluation. The Committee is also responsible for reviewing and approving executive officers’ compensation and establishing performance goals related to their compensation within 90 days of the beginning of each fiscal year. The Committee oversees our benefit plans and evaluates any proposed new retirement or executive benefit plans. The Committee also advises the Board on trends in compensation programs for non-employee directors. The Compensation Committee has the authority to delegate its duties to subcommittees, but to date has not done so. In accordance with Delaware law, in August 2011 the Compensation Committee also delegated to the Chief Executive Officer the authority to approve individual incentive stock option awards to employees of ADTRAN who are not officers, subject to a maximum aggregate limit of 833,682 stock options, and pre-approved terms and conditions.

At the beginning of each calendar year, our Compensation Committee reviews the variable incentive cash compensation (“VICC”) program results from the prior year and approves any payouts thereunder, establishes the performance goals for the current year, approves any increases in executive salaries or other compensation, recommends plan changes, if any, for submission to our stockholders at the annual meeting, and approves the Compensation Committee’s report for our proxy statement. Mid-year the Compensation Committee generally reviews our compensation programs and makes recommendations to the Board regarding outside director compensation and, as necessary throughout the year, approves any equity awards and/or compensation for newly hired or promoted executives. Our Compensation Committee generally meets in the latter part of each calendar year to determine and approve annual equity awards.

Our Compensation Committee generally receives proposals and information from our Chief Executive Officer for its consideration regarding executive and director compensation. Our Chief Executive Officer makes recommendations regarding salary increases, annual cash incentives and equity awards for all of our executive officers other than himself. In doing so, he consults with our Chief Financial Officer.

Our Compensation Committee has authority to retain and terminate any outside advisors, such as compensation consultants. In 2008, the Board of Directors, the Compensation Committee and senior management undertook a review of our compensation policies and practices, including the levels of the various types of compensation that we use for senior managers. Our Compensation Committee has not historically employed compensation consultants to assist it in designing our compensation programs. In connection with the 2008 review, however, at the request of the Compensation Committee we retained the compensation consulting firm of Towers Watson to provide compensation information and analysis with respect to the telecom industry and to our peer companies within the industry. The information provided by Towers Watson was considered by the Compensation Committee, along with other industry surveys and databases, in connection with the equity awards made in November 2008. In 2009, the Compensation Committee and senior management undertook a review of director compensation and retained the compensation consulting firm of Towers Watson to provide compensation information analysis with respect to the telecom industry and to our peer companies within the industry and recommendations with respect to possible changes in compensation for directors. The information provided by Towers Watson was considered by the Compensation Committee, along with other industry surveys and databases, in connection with the equity awards made in November 2009. The Compensation Committee considered this information, together with other industry surveys, studies and databases, in connection with its compensation decisions in 2011. In 2011, the Compensation Committee again engaged Towers Watson to provide compensation information and analysis with respect to the telecom industry and to our peer companies within the industry and recommendations with respect to possible changes in compensation for officers and directors. The Compensation Committee considered this information in connection with compensation decisions for 2012.

Compensation Committee Interlocks and Insider Participation

None of our executive officers or directors serves as a member of the board of directors or compensation committee of any entity that has one or more of its executive officers serving as a member of our Board of Directors or Compensation Committee.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is responsible for assisting the Board in identifying and attracting highly qualified individuals to serve as directors of ADTRAN, selecting director nominees and recommending them to the Board for election at annual meetings of stockholders. The Nominating and Corporate Governance Committee operates under a charter approved by the Board. The charter is posted on our website at www.adtran.com. The Nominating and Corporate Governance Committee is composed of H. Fenwick Huss, Ross K. Ireland, William L. Marks, Balan Nair and Roy J. Nichols, each of whom is independent under NASDAQ listing standards. Mr. Nair is the Chair of the Nominating and Corporate Governance Committee.

Consideration of Director Nominees

The Nominating and Corporate Governance Committee seeks to create a Board that as a whole is strong in its collective knowledge of, and has a diversity of skills and experience with respect to, accounting and finance, management and leadership, vision and strategy, business operations, business judgment, crisis management, risk assessment, industry knowledge, corporate governance and global markets. When the Committee reviews a potential new candidate, the Committee looks specifically at the candidate’s qualifications in light of the needs of the Board and ADTRAN at that time given the then current mix of director attributes.

In accordance with NASDAQ listing standards, we ensure that at least a majority of our Board is independent under the NASDAQ definition of independence, and that the members of the Board as a group maintain the requisite qualifications under NASDAQ listing standards for populating the Audit, Compensation and Nominating and Corporate Governance Committees. The Board has adopted Corporate Governance Principles that set forth the principles that guide us and the Board on matters of corporate governance. The Corporate Governance Principles are posted on our website at www.adtran.com.

As provided in its charter, the Nominating and Corporate Governance Committee will consider nominations submitted by stockholders. To recommend a nominee, a stockholder should write to the Nominating and Corporate Governance Committee, care of James E. Matthews, Secretary of ADTRAN, at 901 Explorer Boulevard, Huntsville, Alabama 35806 (for overnight delivery) or at P.O. Box 140000, Huntsville, Alabama 35814-4000 (for mail delivery). Any recommendation must include:

•

the name and address of the candidate;

•

a brief biographical description, including his or her occupation for at least the last ten years, and a statement of the qualifications of the candidate, taking into account the qualification requirements set forth above; and

•

the candidate’s signed consent to be named in the proxy statement if nominated and to serve as a director if elected.

To be considered by the Nominating and Corporate Governance Committee for nomination and inclusion in our proxy statement for the 2013 Annual Meeting, stockholder recommendations for director must be received by us no later than December 1, 2012. Once we receive the recommendation, we will deliver a questionnaire to the candidate that requests additional information about the candidate’s independence, qualifications and other information that would assist the Nominating and Corporate Governance Committee in evaluating the candidate, as well as certain information that must be disclosed about the candidate in the proxy statement, if nominated. Candidates must complete and return the questionnaire within the time frame provided to be considered for nomination by the Committee.

All of the current nominees for director recommended by the Board for election by the stockholders at the 2012 Annual Meeting are current members of the Board. In evaluating candidates for director, the Committee uses the qualifications described above, and evaluates stockholder candidates in the same manner as candidates from all other sources. Based on the Committee’s evaluation of each nominee’s satisfaction of the qualifications described above and his prior performance as a director, the Committee determined to recommend each incumbent director for re-election. The Committee has not received any nominations from stockholders for the 2012 Annual Meeting.

Communications with the Board of Directors

The Board has established a process for stockholders to communicate with members of the Board. If you have any concern, question or complaint regarding any accounting, auditing or internal controls matter, as well as any issues arising under our Code of Business Conduct and Ethics or other matters that you wish to communicate to ADTRAN’s Audit Committee or Board of Directors, you can reach the ADTRAN Board of Directors through our Corporate Governance Hotline by email at hotline@adtran.com, by mail at ADTRAN, Inc. Hotline, P.O. Box 5765, Huntsville, Alabama 35814, or by calling the hotline at 1-888-723-8726 (1-888-7ADTRAN).

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Overview and Philosophy

The goals of our executive compensation program are to:

•

provide competitive compensation that will help attract, retain and reward qualified executives, with a focus on talent from within the telecommunications industry;

•

align management’s interests with our success by making a portion of the executive’s compensation dependent upon corporate performance; and

•

align management’s interests with the interests of stockholders by including long-term equity incentives.

To achieve these goals, we focus on several key points in the design of our executive compensation program. First, retention is a very important consideration in our compensation programs, and internal promotion and retention of key executive talent has been a significant feature of our company. We believe that retention involves two interrelated components – establishment of a working environment that provides intangible benefits to our executives and encourages longevity and overall compensation that is generally competitive within our industry and among companies of comparable size and complexity. Augmenting compensation with a desirable working environment enables us to maintain an overall compensation program that generally provides overall compensation to our executive officers that is roughly average when compared to companies with which we compete for talent, but still remains competitive with those companies.

In 2008, the Board of Directors, the Compensation Committee and senior management undertook a review of our compensation policies and practices, including the levels of the various types of compensation that we use for senior managers. Our Compensation Committee has not historically employed compensation consultants to assist it in designing our compensation programs. In connection with the 2008 review, however, at the request of the Compensation Committee we retained the compensation consulting firm of Towers Watson to provide compensation information and analysis with respect to the telecom industry and to our peer companies within the industry. The review also included information collected by senior management and the Committee from industry and other sources, surveys and databases, including publicly available compensation information of other companies, both those with which we compete and those within our geographic labor market, to gauge the competitiveness of our compensation programs. As a result of the 2008 review of executive compensation, the Compensation Committee determined that our compensation levels for some senior managers were not competitive within the telecom industry or among our peers. The Committee determined further that these compensation levels should be increased toward a more competitive level in multiple steps over a reasonable time period. The Board concurred.

As discussed in previous years, the equity compensation awards made by the Company for senior managers at the end of 2008, 2009 and 2010 reflected these decisions. The compensation decisions made in 2011 for senior managers continue the theme and represent another step toward attaining more competitive levels of compensation. In 2010, the Company revised its VICC program for executives under our Variable Incentive Compensation Plan and adopted a group of VICC programs designed to encourage and reward growth in net income, and in various categories of revenue. We believe the value of this revised program is reflected in our strong financial performance in 2011.

In 2010, the Compensation Committee and senior management undertook a review of the compensation of certain officers and management employees. As a result of this review, the Compensation Committee determined that to better incentivize officers and managers and to attract and retain qualified executives that the Board, among other things, should consider increasing the maximum performance award that may be awarded in a plan year. As a result of this review, the Company adopted the Variable Incentive Compensation Plan (the “Variable Incentive Compensation Plan”) at the 2011 annual meeting and the maximum performance award to any recipient for any plan year was increased to $3,000,000.

The Compensation Committee also seeks to establish and maintain a compensation structure that is internally consistent and provides appropriate compensation for our executives in relation to one another. Consequently, the Compensation Committee does not focus on any particular benchmark to set executive compensation. Instead, we believe that a successful compensation program requires the application of judgment and subjective determinations based on the consideration of a number of factors. These factors include the following:

•

the scope and strategic impact of the executive officer’s responsibilities, including the importance of the job function to our business;

•

our past financial performance and future expectations;

•

the performance and experience of each individual;

•

past salary levels of each individual and of the officers as a group;

•

our need for someone in a particular position; and

•

for each executive officer, other than the Chief Executive Officer, the evaluations and recommendations of our Chief Executive Officer, in consultation with our Chief Financial Officer.

The Compensation Committee does not assign relative weights or rankings to these factors. Our allocation of compensation between cash and equity awards, our two principal forms of compensation, is based upon our historical practice and our evaluation of the cost of equity awards, as discussed in more detail below.

Our Chief Executive Officer works closely with the Compensation Committee to maintain an open dialogue regarding the Compensation Committee’s goals, progress towards achievement of those goals and expectations for future performance. The Chief Executive Officer updates the Compensation Committee regularly on results and compensation issues. Our Chief Executive Officer also provides the Compensation Committee, and in particular, the Committee Chair, with recommendations regarding compensation for our executive officers other than himself. In part because the Chief Executive Officer works closely with the Compensation Committee throughout the year, the Compensation Committee is in a position to evaluate his performance and make its own determinations regarding appropriate levels of compensation for the Chief Executive Officer.

Components of Executive Compensation

Our executive compensation program consists of base salary, commissions for sales executives, an annual VICC program, and long-term equity incentives in the form of stock options and performance-based restricted stock units. Executive officers also are eligible to participate in a nonqualified deferred compensation program (and the Board approved the inclusion of directors in this program beginning in 2010) and in certain benefit programs that are generally available to all of our employees, such as medical insurance programs, life insurance programs and our 401(k) plan. The Compensation Committee of our Board of Directors oversees our executive compensation program.

Base Salary and Commissions. Base salaries are the most basic form of compensation and are integral to any competitive employment arrangement. At the beginning of each fiscal year, the Compensation Committee establishes an annual base salary for our executive officers as well as commission structures for our sales executives, based on recommendations made by our Chief Executive Officer, in consultation with our Chief Financial Officer. Consistent with our compensation objectives and philosophy described above, the Compensation Committee attempts to set base salary compensation, and adjust it when warranted, based on company financial performance, the individual’s position and responsibility within our company and performance in that position, the importance of the executive’s position to our business, and the compensation of other executive officers of ADTRAN with comparable qualifications, experience and responsibilities. The Committee also generally takes into account its perceived range of salaries of executive officers with comparable qualifications, experience and responsibilities at other companies with which we compete for executive talent. In 2008, the Committee engaged Towers Watson to support that effort. In 2009, 2010 and 2011, however, the Committee did not use a compensation consultant with respect to executive compensation, but did use statistics and information received from Towers Watson as well as other industry sources, studies and databases in considering executive compensation.

For our sales executives, commissions are an important element of cash compensation, because they tie the executive’s pay directly to his success in his area of responsibility. Our sales executives generally receive half of their cash compensation (not including annual VICC, if any) in salary and half in commissions, which is consistent with our historical practice and our understanding of the standard practice in the market for these executives. The Committee also reviews historical salary and commission information for each of the executive officers as part of its analysis in setting base salaries and commission structures. The Committee uses this information to review historical progression of each executive officer’s compensation and to identify variations in compensation levels among the executive officers.

In January, 2011, the Compensation Committee reviewed the base salaries of our executive officers, taking into account the considerations described above. The Committee approved salary increases for each of the named executive officers which are reflected in the following table:

		September 30,		September 30,
Named Executive Officer	2010 Base Salary		2011 Base Salary

Thomas R. Stanton	$	510,000	$	535,000
James E. Matthews	$	300,000	$	309,000
Raymond R. Schansman	$	267,370	$	278,065
James D. Wilson, Jr.	$	266,990	$	280,340
Michael Foliano	$	271,436	$	279,579

Annual Incentive Compensation. We provide our executives the opportunity to earn annual VICC under our Variable Incentive Compensation Plan, which is designed to motivate and reward executives for their contribution to ADTRAN’s performance during the fiscal year. A significant portion of the total cash compensation that our executive officers could receive each year is paid through this program, and thus is dependent upon our corporate performance. VICC available for 2011 was determined by a formula based on designated performance measures for total company net income, total company revenue, total international revenue, total carrier network revenue and for total enterprise network revenue, as described in the narrative following the Summary Compensation Table and the Grants of Plan-Based Awards table. We use these performance measures for our annual incentive awards because we consider them as the most appropriate drivers of stockholder value. Total company net income and total company revenue performance measures required a growth rate of at least 2.5% in that measure over the prior year’s performance for officers to receive any VICC. The Committee does not have the discretion under the Variable Incentive Compensation Plan to grant a VICC award absent attainment of the minimum performance measures. The Committee has the discretion to decrease a VICC payout under the plan even if performance measures are met, but the Committee does not have any discretion under the plan to increase a VICC payout above the amount determined pursuant to the established VICC formula.

For 2011 the Company met, and substantially exceeded, all of the performance measures established for the 2011 program under the Variable Incentive Compensation Plan. Consequently, our executives did earn bonuses for 2011 performance under that plan and we awarded those amounts. These awards were recommended by the Compensation Committee and approved by the Board of Directors at its January 17, 2012 meeting.

As a result, our named executive officers were awarded the following amounts for 2011:

		September 30,
Named Executive Officer	2011 Award

Thomas R. Stanton	$	1,440,000
James E. Matthews	$	350,000
Raymond R. Schansman	$	310,000
James D. Wilson, Jr.	$	310,000
Michael Foliano	$	200,000

Long-Term Incentive Awards. We compensate our executive officers in part with annual grants of stock option awards under our 2006 Employee Stock Incentive Plan, which is described in the narrative following the Summary Compensation Table and the Grants of Plan-Based Awards table. We grant stock options every year because these awards are consistent with our compensation goals of aligning executives’ interests with those of our stockholders in the long term, and because these awards are a standard form of compensation among the companies with which we compete for executive talent. The Compensation Committee believes that stock option awards are an especially valuable tool in linking the personal interests of executives to those of our stockholders, because executives’ compensation under these awards is directly linked to our stock price. These awards give executive officers a significant, long-term interest in ADTRAN’s success. In addition, they can provide beneficial tax treatment that executives value due to the fact that we have typically granted incentive stock options to our executives to the maximum extent permitted under the tax laws. Moreover, the vesting component of our stock option awards provides a valuable retention tool, and retention is a significant consideration in making these awards.

As discussed above under “Overview and Philosophy,” in 2008 the Compensation Committee, based on discussions with the Chief Executive Officer and after considering information received from Towers Watson and other industry surveys and databases, determined to add an additional equity component in the form of performance-based restricted stock units, referred to as “performance shares,” for the Chief Executive Officer and the Senior Vice Presidents. The Committee chose this form of award to further implement our executive compensation goals of better aligning the interests of these executives, who can most directly impact our overall financial performance, with the interests of our stockholders and of our Company by making the awards dependent on corporate performance, and allocated a portion of the long-term incentive awards for these executive officers accordingly. The number of performance shares earned by the executive officers is based on our relative total shareholder return, or “TSR,” against a peer group over a three-year performance period. For 2011, the Compensation Committee selected as a peer group all companies in the NASDAQ Telecommunications Index. The Committee chose this index based on the fact that it contains a significant number of companies and is a broad sample of our industry.

As discussed in more detail below in the narrative following the Grants of Plan-Based Awards table, depending on our relative TSR over the performance period, the executive officers may earn from 0% of the number of target performance shares if the relative TSR performance is not at least equal to the 20^th percentile of the peer group, to 150% of the number of target performance shares if relative TSR performance equals or exceeds the 80th percentile of the peer group. Shares earned are distributed at the end of the three-year performance period. Under the award agreements, a portion of the granted performance shares also vest and become deliverable upon the death or disability of a recipient or upon a change of control of ADTRAN, as discussed in more detail below under the heading “Potential Payments Upon Termination or Change of Control.” The recipients of the performance shares under the award agreements receive dividend credits based on the shares of common stock underlying the performance shares. The dividend credits are paid in cash upon vesting of those shares under the applicable awards.

The 2008 grant of performance shares vested on November 6, 2011 and the Compensation Committee certified during its November 2011 meeting that the TSR relative to its peer group over the performance period was at least 85%. As a result, the recipients earned 150% of the performance shares originally granted and payment, in cash, of the dividend credits accrued on such performance shares.

Our long-term equity incentive awards are timed to occur in the latter part of each year, to coincide with an open trading window under our insider trading policy. In August 2011, the Compensation Committee approved stock option awards to our executive officers that vest over a four year period, with 25% vesting on each anniversary of the grant date. In addition, in November 2011, the Committee approved performance share awards to the Chief Executive Officer and the Senior Vice Presidents, as discussed above. The total awards to the named executive officers in 2011 were as follows, and are described in the narrative below the Grants of Plan-Based Awards table:

		September 30,		September 30,
Named Executive Officer	2011 Stock Option Award		2011 Performance Share Award
Thomas R. Stanton		75,366		13,547
James E. Matthews		21,942		4,000
Raymond R. Schansman		20,034		3,100
James D. Wilson, Jr.		20,034		3,100
Michael Foliano		18,062		3,100

In determining the amount of these incentive equity awards, the Compensation Committee began by deciding on an overall pool amount for the company, taking into account the estimated expense to us of the awards and the earnings per share impact of that expense. We typically establish an internal target for the aggregate expense from company-wide option awards and performance shares, which, based on our review of industry data as discussed above, we believe is at the low end of the expense levels incurred by our competitors. The Committee established a pool of up to 1,016,602 stock options and 26,847 performance shares for the 2011 annual grant, as compared to a pool of up to 907,200 stock options and 24,788 performance shares for the 2010 annual grant. The Committee allocated the pool of options and performance shares among the different functions throughout the company, based on the importance and performance of the function and considerations such as retention and competitive compensation levels. The Compensation Committee then set each executive’s individual award from the amount allocated to the function in which he serves, based on the recommendation of our Chief Executive Officer with input from our Chief Financial Officer. In determining the amount of the options awards and performance shares for the named executive officers, the Committee considered the conclusions of its 2011 compensation review described above.

The Company has not historically included a performance measure as a component of vesting of stock options for executive officers because we believe that performance of the Company is an implicit feature of every stock option and that the option itself provides significant incentive to each employee who receives an option (including our executives) to perform his or her job tasks optimally for the overall performance of his or her group and the Company as a whole. It does include performance as the entire measure for the performance-based restricted stock units (or “performance shares”) program described below at “Grants of Plan-Based Awards in 2011 – Equity Compensation” at page 18.

Other Compensation. We maintain general broad-based employee benefit plans in which our executives participate, such as a health insurance plan and a 401(k) plan. These benefits are provided as part of the basic conditions of employment for all of our employees, and therefore providing them to our executive officers does not represent a significant incremental cost to us. In addition, we believe that providing these basic benefits is necessary for us to attract talented executives. We also maintain a nonqualified deferred compensation plan, which is described under the Nonqualified Deferred Compensation table below. This plan permits executives and directors to voluntarily defer a portion of their income and performance shares and save money for retirement on a tax-deferred basis. Although the plan permits discretionary employer contributions, to date we have not made any contributions to this plan. Therefore, this plan provides a valuable benefit to executives and directors at virtually no cost to us.

As described in more detail under “Potential Payments Upon Termination or Change of Control” below, we provide limited benefits to participants upon a change of control or upon termination of employment for specified reasons (provided, in some cases, that termination must be a “separation from service” as defined in Section 409A of the Internal Revenue Code) including the named executive officers, in our equity incentive plans and our Variable Incentive Compensation Plan. All of these benefits are consistent with the basic benefits provided by the companies with which we compete for executive talent and help us to attract valuable executives. These benefits help to provide additional security that executives may need and reward loyal service in situations that create insecurity and present special challenges for executives. We provide the limited change of control benefits to encourage our executives to seek out and pursue business transactions that could be beneficial to ADTRAN and its stockholders.

Tax Considerations

Section 162(m) of the Internal Revenue Code limits ADTRAN’s tax deduction for compensation over $1,000,000 paid to the Chief Executive Officer or to certain other executive officers. Compensation that meets the requirements for qualified performance-based compensation or certain other exceptions under the Internal Revenue Code is not included in this limit. Generally, the Compensation Committee desires to maintain the tax deductibility of compensation for executive officers to the extent it is feasible and consistent with the objectives of our compensation programs. To that end, our 2006 Employee Stock Incentive Plan and Variable Incentive Compensation Plan were designed to meet the requirements so that awards and annual VICC under those plans will be performance-based compensation for Section 162(m) purposes. However, in the past, our executives’ compensation has not been high enough to make Section 162(m) a critical issue for ADTRAN. Therefore, deductibility under Section 162(m) is only one consideration in determining executive compensation, and the Compensation Committee may approve compensation that is not deductible in order to compensate executive officers in a manner consistent with performance and our need for executive talent.

Risk Assessment

We have evaluated our compensation program and each element of the program to ensure that our policies and practices do not create risks that are reasonably likely to have a material adverse effect on ADTRAN. The Compensation Committee has attempted to create a compensation system that values current goals along with long-term growth. While the use of annual cash incentive opportunities creates the potential for short term risk taking, we believe the risk is more than offset by the fact that an annual cash incentive is only one of three elements of our overall compensation program; and the Compensation Committee has the ability to utilize discretion to reduce the amount of annual cash incentive awards if an executive officer takes unnecessary risks.

We believe the two other elements of our total compensation program – base salaries and long term equity awards – are either risk neutral or help lower risk. The Compensation Committee determines the annual base salaries based on numerous factors, as discussed above. These factors lend themselves to an overall evaluation that emphasizes improvement of ADTRAN and its operations rather than taking risks for short term gain. Our equity incentive awards vest or are earned over several years, so while the potential compensation an executive can receive through equity incentive awards is tied directly to appreciation of our stock price or other performance metrics, taking excessive risk for a short term gain is incompatible with an executive officer maximizing the value of equity incentive awards over the long term.

We believe that the Company’s performance in 2011 is an indication that our risk-benefit considerations with respect to compensation are contributing to the development of long-term shareholder value.

Clawback Policy

The Board has adopted a policy providing that, in the event the Company is required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws, the Company will recover incentive-based compensation paid to current or former executive officers of the Company during the three years prior to the date as of which the accounting restatement is required, to the extent that any of that compensation was based upon the erroneous data that made the restatement necessary. Under this policy, incentive-based compensation includes stock options, performance shares and other monetary or equity-based compensation awards. To implement this policy, the Board has entered into an agreement with each of the named executive officers providing for their agreement to such repayment and, under the policy, will do so at the close of each fiscal year.

Policy Against Hedging Instruments

Under the Company’s Insider Trading Policy, employees and directors of the Company and any designee of any employee or director, are prohibited from purchasing financial instruments (including, but not limited to, prepaid variable forward contracts, equity swaps, collars, exchange funds, and options) that are designed to hedge or offset any decrease in the market value of equity securities held directly or indirectly by the employee or director.

Annual Incentive Awards

We provide our named executive officers with the opportunity to earn annual VICC under our Variable Incentive Compensation Plan. Under the Variable Incentive Compensation Plan, within 90 days of the beginning of each year, our Compensation Committee establishes corporate goals to determine the eligibility for, and amount of, any annual incentive compensation for our executives. The Compensation Committee also determines the eligible individuals to receive awards and establishes the terms and conditions of all awards under the Variable Incentive Compensation Plan.

In January 2011, our Compensation Committee established a group of VICC programs under the Variable Incentive Compensation Plan to determine 2011 amounts and designated each executive as a participant in a particular program. Each program was designed to encourage growth in company net income and company revenue, including international revenue, carrier networks revenue and enterprise networks revenue. VICC was available under each program only if both of certain minimum net income and revenue thresholds were achieved. If these minimum thresholds were achieved, VICC was available in three categories: net income, revenue and international revenue. VICC was scaled depending upon the amount of growth the company experienced in excess of the minimum threshold in any category. In order to measure the value of each possible VICC award, the programs assigned to each participating executive a number identified as the target VICC. VICC available in each category was expressed as percentages of the target VICC and ranged from a small percentage if the required threshold was reached through the possibility of as much as 200% of the target VICC. In no event could any executive receive more than 200% of the target VICC in any combination of VICC awards for all categories. In determining the target VICC for each executive the Compensation Committee considered, among other things, the executive’s responsibilities and opportunity to influence the outcomes in the several categories under which VICC could be earned as well as the executive’s prior contributions to company performance.

Under the program in which Messrs. Stanton, Matthews and Foliano participated, they could earn VICC only if each of total company net income and total company revenue grew by at least 2.5% over the prior year. If these two threshold growth measures were both achieved, they could earn VICC for growth in any one of total company net income, total company revenue or total company international revenue (if total company international revenue grew by at least 7.5%). The maximum amount of VICC was available if total company net income grew by 60%, if total company revenue grew by 44.44%, or if total international revenue grew by 133.33%. At the minimum thresholds Mr. Stanton could earn $81,000 for each of total company revenue growth and total international revenue growth and $72,000 for total company net income growth. At the minimum thresholds Mr. Matthews could earn $19,688 for each of total company revenue growth and total international revenue growth and $17,500 for total company net income growth. At the minimum thresholds Mr. Foliano could earn $11,250 for each of total company revenue growth and total international revenue growth and $10,000 for total company net income growth. In fact, the increases which the Company achieved for the three components were well in excess, in the aggregate, of the amounts that entitled the executive to the maximum award available and each of Messrs. Stanton, Matthews and Foliano earned the maximum amount available as reflected in the table above and in the Summary Compensation Table.

Under the program in which Mr. Schansman participated, he could earn VICC only if each of total company net income and total enterprise networks revenue grew by at least 2.5% over the prior year. If these two threshold growth measures were both achieved, he could earn VICC for growth in any one of total company net income, total enterprise networks revenue or total company international revenue (if total company international revenue grew by at least 7.5%). The maximum amount of VICC was available if total company net income grew by 60%, if total enterprise networks revenue grew by 44.44%, or if total international revenue grew by 133.33%. At the minimum thresholds Mr. Schansman could earn $17,438 for each of total enterprise networks revenue growth and total international revenue growth and $15,500 for each of total company net income growth. In fact, the increases which the Company achieved for the three components were well in excess, in the aggregate, of the amounts that entitled the executive to the maximum award available and Mr. Schansman earned the maximum amount of VICC available as reflected in the table above and in the Summary Compensation Table.

Under the program in which Mr. Wilson participated, he could earn VICC only if each of total company net income and total carrier networks revenue grew by at least 2.5% over the prior year. If these two threshold growth measures were both achieved, he could earn VICC for growth in any one of total company net income, total carrier networks revenue or total company international revenue (if total company international revenue grew by at least 7.5%). The maximum amount of VICC was available if total company net income grew by 60%, if total carrier networks revenue grew by 44.44%, or if total international revenue grew by 133.33%. At the minimum thresholds Mr. Wilson could earn $17,438 for each of total carrier networks revenue growth and total international revenue growth and $15,500 for each of total company net income growth. In fact, the increases which the Company achieved for the three components were well in excess, in the aggregate, of the amounts that entitled the executive to the maximum award available and Mr. Wilson earned the maximum amount of VICC available as reflected in the table above and in the Summary Compensation Table.

Actual VICC amounts awarded to our named executive officers for 2011 under the Variable Incentive Compensation Plan are included in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table above.

Equity Compensation

We granted stock options and performance-based restricted stock units, or “performance shares,” during 2011 to our named executive officers under the ADTRAN, Inc. 2006 Employee Stock Incentive Plan. The Stock Incentive Plan permits awards of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock and restricted stock units. Our Compensation Committee administers the Stock Incentive Plan, determines who will receive awards and establishes the terms and conditions of all awards. The total number of remaining shares authorized for grant for awards other than options under all equity compensation plans at December 31, 2011 was 3,172,420 shares.

The per share exercise price of the options we granted to our named executive officers during 2011 was equal to the fair market value of a share of our common stock on the date of grant. Fair market value is defined in the Stock Incentive Plan as the closing price of our common stock on the business day immediately before the date of grant. The option price may be paid in cash, in shares of our common stock, by broker-assisted cashless exercise (if permitted by applicable laws and regulations), or by any other method permitted by the Committee.

The options we granted in 2011 to our named executive officers will become exercisable with respect to 25% of the shares on each of the first four anniversaries of the grant date. The options become immediately vested and exercisable upon the executive’s death or disability, and upon a change of control. The options may be exercised for one year after termination due to the executive’s death, disability or retirement, or for 90 days after termination for any other reason other than for cause, in which case the options immediately terminate. In addition, the Compensation Committee, in its discretion, may accelerate the vesting at any time. The provisions regarding acceleration of the options are described in more detail in the section on the Stock Incentive Plan below under the heading entitled “Potential Payments Upon Termination or Change of Control.”

The number of performance shares earned by the executive officers under the 2011 grant is based on our relative total shareholder return, or “TSR,” against a peer group over a three-year performance period. The peer group is set forth above in “Compensation Discussion and Analysis – Components of Executive Compensation – Long-Term Incentive Awards.” Depending on our relative TSR over the performance period, the executive officers may earn shares of common stock on a sliding scale from 0% to 150% of the performance shares granted depending on our relative TSR performance against the peer group, as shown below:

		September 30,
ADTRAN’s TSR Performance Relative to its Peer Group (expressed in a percentile)	Granted Performance Shares Earned (expressed as a percentage)
Less than 20th Percentile		0	%
20th Percentile		25	%
25th Percentile		38	%
30th Percentile		50	%
35th Percentile		63	%
40th Percentile		75	%
45th Percentile		88	%
50th Percentile		100	%
55th Percentile		108	%
60th Percentile		117	%
65th Percentile		125	%
70th Percentile		133	%
75th Percentile		142	%
80th or more Percentile		150	%

Shares earned are distributed at the end of the three-year performance period and after that time there is no additional holding period for the shares. Under the award agreements, a portion of the granted performance shares also vest and become deliverable upon the death or disability of a recipient or upon a change of control of ADTRAN, as discussed in more detail below under the heading “Potential Payments Upon Termination or Change of Control.” The recipients of the performance shares under the award agreements receive dividend credits based on the shares of common stock underlying the performance shares. The dividend credits are vested, earned and distributed in the same manner as the performance shares. Recipients may choose to defer shares under the Deferred Compensation Plan instead of receiving the shares at the time they are entitled to distribution of the shares.

We maintain the ADTRAN Inc. Deferred Compensation Plan. This plan is offered as a supplement to our tax-qualified 401(k) plan and is available to our officers and directors who have been duly appointed or elected by our Board of Directors. The deferred compensation plan allows participants to defer a portion of their salaries and all or a portion of their annual VICC and performance shares, and permits us to make matching contributions on a discretionary basis, without the limitations that apply to the 401(k) plan. To date, we have not made any matching contributions under this plan. All contributions are unfunded and are credited to bookkeeping accounts for the participants, although we have set aside assets in a rabbi trust to pay for the benefits under this plan. Each participant’s account is credited with earnings as if the account were invested as elected by the participant among pre-approved mutual funds. Benefits are usually distributed or begin to be distributed on the 1^st day of the month following the six month anniversary of the participant’s separation from service. Benefits will be paid in a single lump sum cash payment and any deferred stock awards will be paid in whole shares of ADTRAN common stock with fractional shares paid in cash; provided that a participant may, in some cases, elect to receive a portion of his or her benefit in installments paid over 3 or 10 years.

Potential Payments Upon Termination or Change of Control

This section describes the limited benefits that would be provided to our named executive officers under our executive compensation plans upon a change of control of ADTRAN or following termination of employment (provided, in some cases further described below, the termination must be a “separation from service” as defined in Section 409A of the Internal Revenue Code). We also provide a table below showing the potential benefits payable to each of our named executive officers upon a change of control of ADTRAN or following termination of employment as of December 31, 2011.

Variable Incentive Compensation Plan

Under the ADTRAN, Inc. Variable Incentive Compensation Plan, in the event of a change of control of ADTRAN, each executive will receive an immediate lump sum cash payment of the then-applicable annual VICC, but only if the performance measures set by the Compensation Committee for the relevant fiscal year have been attained as of the date of the change of control. The amount of the performance award would be consistent with the minimum, target or maximum level of performance measures actually achieved as of the change of control and would be for a proportionate share of the annualized amount for the part-year period ending on the change of control event. If there had been a change of control of ADTRAN on December 31, 2011, our executive officers would have received a payment under this provision, because the minimum levels required under the 2011 performance measures had been attained.

Under the plan, a change of control would occur if:

(1)

any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) acquires more than 50% of the total fair market value or total voting power of our stock;

(2)

any person or group acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) ownership of 35% or more of the total voting power of our stock;

(3)

a majority of our Board members is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board; or

(4)

any person or group acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) at least 40% of the total gross fair market value of all of our assets.

Deferred Compensation Plan

Under the ADTRAN Inc. Deferred Compensation Plan, participants are entitled to receive their benefits upon termination of employment (provided the termination is a “separation from service” as defined in Section 409A of the Internal Revenue Code). The amount they receive is based on their account balance, which would consist of their contributions to the plan and any earnings as described above in the Nonqualified Deferred Compensation table and its accompanying narrative. Benefits are not payable from the plan until the 1^st day of the month following the six month anniversary of the participant’s separation from service.

2006 Employee Stock Incentive Plan

Under our 2006 Employee Stock Incentive Plan, the options we have granted will become immediately vested and exercisable upon the executive’s death or disability, or upon a change of control. Upon termination of employment for cause, all outstanding options immediately terminate. Options may be exercised for one year upon termination due to the executive’s death, disability or retirement, or for 90 days after termination for any other reason other than for cause. Under the award agreements, with respect to the performance shares granted under our 2006 Employee Stock Incentive Plan, a portion of the performance shares become immediately vested and earned in the event of death, disability, or upon a change of control. The number of such vested performance shares equals 25% of the total performance shares granted multiplied by a fraction, the numerator of which equals the number of days elapsed from the date of grant to the date of the applicable acceleration event and the denominator of which equals the days in the performance period.

Under the 2006 Employee Stock Incentive Plan, change of control is defined as:

(1)

the acquisition of beneficial ownership of 50% or more of either our outstanding shares of common stock or the combined voting power of our securities, except for any acquisition directly from us, any acquisition by us or our affiliates, or any acquisition by any of our employee benefit plans;

(2)

during any 12-month period, a majority of the Board is no longer comprised of individuals who, as of the beginning of that period, constituted our Board and individuals whose nomination for election was approved by the Board;

(3)

a reorganization, merger or consolidation, where substantially all of the owners, respectively, of our outstanding shares of common stock or the combined voting power of our securities immediately before the transaction beneficially own less than 50% of, respectively, the common stock and the combined voting power of the securities of the resulting corporation, in substantially the same proportions as their ownership immediately prior to the transaction; or

(4)

the sale or other disposition of all or substantially all of our assets.

An executive is considered retired under the 2006 Employee Stock Incentive Plan if he terminates employment after age 65. Disability is defined as eligibility to receive long-term disability benefits or, if we do not have a long-term disability plan, an executive’s inability to engage in the essential functions of his or her duties due to a medically-determinable physical or mental impairment, illness or injury, which can be expected to result in death or to be of long-continued and indefinite duration. Cause means the executive’s willful and continued failure to perform his duties within 15 days after receipt of written demand for such performance; unlawful or willful misconduct which is economically injurious to us or our affiliates; conviction of, or a plea of guilty or nolo contendere to, a felony charge (other than a traffic violation); habitual drug or alcohol abuse that impairs the executive’s ability to perform his duties; embezzlement or fraud; competition with our business; or the executive’s breach of his employment contract, if any. Currently, none of our executives have employment contracts.

1996 Employees Incentive Stock Option Plan

Under our 1996 Employees Incentive Stock Option Plan, the options we have granted will become immediately vested and exercisable upon the executive’s death or disability, or upon a change of control. Upon termination of employment for cause, all outstanding options immediately terminate, unless the executive is terminated for cause after a change of control, in which case the options may be exercised for three months after termination. Options may be exercised for one year upon termination due to the executive’s disability or the executive’s death while an employee, or for three months after termination for any reason other than for cause (or the option’s expiration date, if earlier).

Disability under the 1996 plan is defined as total and permanent disability as determined by our Compensation Committee in its sole discretion. Change of control is defined as: (1) the acquisition by a person, group or entity of a sufficient number of shares of our common stock, or securities convertible into our common stock, to hold more than 50% of our common stock; or (2) any sale or other disposition of all or substantially all of our assets. Cause under the 1996 plan means acts by an executive that cause us liability or loss involving: personal dishonesty, incompetence, willful misconduct, moral turpitude, intentional failure to perform stated duties, willful violation of any law, rule or regulation (other than traffic violations or similar offenses), improper use or disclosure of our confidential information or trade secrets, the breach of any contract with ADTRAN, the unlawful trading in securities based on information gained through the performance of services for us, a felony conviction or the failure to contest prosecution for a felony, embezzlement, fraud, deceit or civil rights violations.

The following table sets forth the potential benefits payable to our named executive officers pursuant to the arrangements described above, assuming termination of employment or a change of control had occurred on December 31, 2011.

(1)

Amounts represent the potential value of unvested stock options held by the named executive officers under the 2006 Stock Incentive Plan and the 1996 Incentive Stock Option Plan that would have vested upon a change of control or upon termination of employment by reason of death or disability on December 31, 2011, based on a price of $30.16 per share, the closing price of our common stock on December 31, 2011.

(2)

Amounts represent the potential value of unvested performance shares that would have vested upon a change of control or upon termination of employment by reason of death or disability on December 31, 2011, based on a price of $30.16 per share, the closing price of our common stock on December 31, 2011.

(3)	Represents the amount of the annual VICC that would have been payable to each participant upon a change of control on December 31, 2011.

(4)

Represents the amount payable under the Deferred Compensation Plan upon a termination of employment (provided the termination is a “separation from service” as defined in Section 409A of the Internal Revenue Code), including a termination by reason of death or disability, to each participant on December 31, 2011. These amounts equal the account balance of each participant as of December 31, 2011.

(5)	Reflects the sum of (1) the value of accelerated vesting of stock options; (2) the value of shares of common stock received upon partial vesting of unvested performance shares; and (3) amounts payable under the Variable Incentive Compensation Plan, in each case as of December 31, 2011.

(6)	Reflects the sum of (1) the value of accelerated vesting of stock options; (2) the value of shares of common stock received upon partial vesting of unvested performance shares; and (3) amounts payable under the Deferred Compensation Plan, in each case as of December 31, 2011.

(7)	Represents amounts payable to each participant under the Deferred Compensation Plan upon termination of employment for any reason (provided the termination is a “separation from service” as defined in Section 409A of the Internal Revenue Code) on December 31, 2011.

(8)

Amounts represent the sum of the potential value of unvested stock options as described in Footnote 1 above, the potential value of unvested performance shares as described in Footnote 2 above, and the amount of the annual VICC that would have been payable as described in Footnote 3 above as a multiple of the salary and VICC received by each individual for the year ending December 31, 2011 as disclosed at Summary Compensation Table above. The amounts payable under the Deferred Compensation Plan are excluded from this calculation because all amounts included in the Plan are amounts of compensation deferred by the executive and the earnings on such amounts and do not include any Company contributions. Under the Company’s change of control arrangements, there is no salary payable upon a change of control other than salary earned but unpaid to the time of the change of control.

Non-employee directors of ADTRAN, including Mr. North, our director emeritus, were paid an annual fee of $60,000, plus an annual retainer of $5,000 paid to the Nominating and Corporate Governance Committee chairperson, plus an annual retainer of $10,000 paid to the Audit Committee chairperson, plus an annual retainer of $7,500 paid to the Compensation Committee chairperson. In January 2011, the Board approved the payment of an annual fee of $15,000 to the director serving as lead director. This annual fee is in addition to all other fees received for services as a director or as a member or chairman of a committee of the Board. Directors who are employees of ADTRAN receive no directors’ fees. All directors are reimbursed for their reasonable expenses in connection with the performance of their duties.

Our non-employee directors, including our current director emeritus, are entitled to participate in our 2010 Directors Stock Option Plan, which our stockholders approved at the 2010 annual meeting of stockholders on May 5, 2010. As of December 31, 2011, there were a total of 500,000 shares reserved for issuance under the 2010 Directors Stock Option Plan, of which 150,000 shares were subject to outstanding options, 21,828 were issued as restricted stock awards and 328,172 shares were available for future awards. The 2010 Directors Stock Option Plan provides for automatic equity grants to directors who are not otherwise employees of ADTRAN. Under the 2010 Directors Stock Option Plan newly-elected directors may receive an initial grant and an annual grant in the same calendar year. As of December 31, 2011, there were five directors and one director emeritus eligible to participate in the 2010 Directors Stock Option Plan. The 2010 Directors Stock Option Plan is administered by the Compensation Committee. Subject to the terms of the 2010 Directors Stock Option Plan, the Compensation Committee has the authority to determine the terms and provisions of the option agreements, to interpret the provisions of the plan, to prescribe, amend and rescind any rules and regulations relating to the plan, and to make all determinations necessary or advisable for the administration of the plan.

Equity grants (nonqualified stock options, restricted stock or restricted stock units) under the 2010 Directors Stock Option Plan have a fixed dollar value determined by reference to a percentage of the Directors’ total remuneration. The annual equity grant has a value equal to 50% of the Directors’ total remuneration for the calendar year (which includes the award under the 2010 Directors Stock Option Plan and excludes any compensation for serving as a committee chair or lead director or any additional meeting fees), or a lesser amount as determined in the discretion of our Board. In no event shall any annual equity award have a fair market value greater than $120,000. In addition, upon initially joining the Board, a new Director will receive an initial award equal to 50% of the value of the annual grant (detailed above) that was granted in the calendar year prior to the calendar year in which the new Director joins the Board, or a lesser amount as determined in the discretion of our Board. The initial grant will be in addition to any annual grant. Grants under the 2010 Directors Stock Option Plan are in the form of restricted stock, unless our Board (upon recommendation from the Compensation Committee) determines to grant awards in the form of restricted stock units or nonqualified stock options.

Options granted under the 2010 Directors Stock Option Plan (whether in the form of restricted stock, nonqualified stock options or restricted stock units) vest in full on the first anniversary of the grant date, unless the vesting schedule is varied by the Compensation Committee in the Director’s award agreement. Awards vest earlier if there is a change of control of ADTRAN or if the Director terminates service due to death or disability. The term of any nonqualified stock option is ten years from the date of grant. The Compensation Committee is given the discretion under the 2010 Directors Stock Option Plan to extend this exercise period for outstanding options to the extent permitted by Section 409A of the Internal Revenue Code. The purchase price of the common stock underlying each nonqualified stock option granted under the 2010 Directors Stock Option Plan is 100% of the fair market value of the common stock on the date the option is granted. There is no purchase price for an award of restricted stock or restricted stock units.

If a Director’s service with ADTRAN is terminated for cause, all nonqualified stock options will terminate immediately. Upon termination of a Director’s service due to disability, the nonqualified stock options may be exercised for one year. Upon termination of a Director’s service other than due to death, disability or cause, the nonqualified stock options may be exercised for three months. In addition, if a Director dies while his nonqualified stock options remain exercisable, his beneficiary (as determined under the 2010 Directors Stock Option Plan) may exercise the options for up to one year after the date of death. However, in no case will any option remain exercisable beyond its term. Under the 2010 Directors Stock Option Plan, “cause” is defined as an act or acts by an individual involving personal dishonesty, incompetence, willful misconduct, moral turpitude, intentional failure to perform stated duties, willful violation of any law, rule or regulation (other than traffic violations or similar offenses), the use for profit or disclosure to unauthorized persons of our confidential information or trade secrets, the breach of any contract with us, the unlawful trading in our securities or the securities of another corporation based on information gained as a result of the performance of services for us, a felony conviction or the failure to contest prosecution for a felony, embezzlement, fraud, deceit or civil rights violations, any of which acts cause us liability or loss, as determined by the Compensation Committee in its sole discretion. Under the plan, “disability” means the total and permanent disability of an individual as determined by the Compensation Committee in its sole discretion. In addition, if a director dies during service, or during a period following termination of service when his options have not yet terminated as provided above, the director’s beneficiary can exercise the options for up to one year after the date of the director’s death (or the expiration of the option, if earlier). If an individual ceases to be a Director, his rights with regard to all non-vested restricted stock and restricted stock units granted under the 2010 Directors Stock Option Plan cease immediately.

On December 31, 2011, in accordance with the terms of the 2010 Directors Stock Option Plan, 1,989 shares of restricted stock were granted to each of Messrs. Ireland, Marks, Nair, Nichols and North and Dr. Huss.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

James L. North, a partner in the law firm of James L. North & Associates, is our director emeritus and as of December 31, 2011, beneficially owned 119,654 shares of our common stock. We paid James L. North & Associates fees of $110,000 for legal services rendered to us during 2011. All bills for services provided by James L. North & Associates are reviewed and approved by our Chief Financial Officer. We believe that the fees for these services are reasonable and comparable to those charged by other firms for services rendered to us.

Policies and Procedures For Review and Approval of Related Person Transactions

We believe that business decisions and actions taken by our officers, directors and employees should be based on the best interests of ADTRAN, and must not be motivated by personal considerations or relationships. We attempt to analyze all transactions in which ADTRAN participates and in which a related person may have a direct or indirect material interest, both due to the potential for a conflict of interest and to determine whether disclosure of the transaction is required under applicable SEC rules and regulations.

Related persons include any of our directors or executive officers, certain of our stockholders and their immediate family members. A conflict of interest occurs when an individual’s private interest interferes, or appears to interfere, in any way with the interests of ADTRAN. Our Code of Business Conduct and Ethics requires all directors, officers and employees who may have a potential or apparent conflict of interest to fully disclose all the relevant facts to either a personnel supervisor, if applicable, or the Director of Internal Audit. Once a personnel supervisor receives notice of a conflict of interest he or she will report the relevant facts to the Director of Internal Audit. The Director of Internal Audit will then generally consult with the Audit Committee and a determination will be made as to whether the activity is permissible. A copy of our Code of Business Conduct and Ethics is available on our website at www.adtran.com under the links “Investor Relations – Corporate Governance –ADTRAN Code of Business Conduct and Ethics.”

In addition to the reporting requirements under the Code of Business Conduct and Ethics, each year our directors and officers complete Directors’ and Officers’ Questionnaires identifying any transactions with us in which the officer or director or their family members have an interest. A list is then maintained by us of all companies known to ADTRAN that are affiliated with a related person. Any potential transactions with such companies or other related party transactions are reviewed by the Chief Financial Officer and brought to the attention of the Audit Committee as appropriate. Our Audit Committee is responsible for reviewing and approving all material transactions with any related person.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act, and regulations of the SEC thereunder, require our directors, officers and persons who own more than 10% of our common stock, as well as certain affiliates of those persons, to file with the SEC initial reports of their ownership of our common stock and subsequent reports of changes in that ownership. Directors, officers and persons owning more than 10% of our common stock are required by SEC regulations to furnish us with copies of all Section 16(a) reports they file. Based solely on our review of the copies of these reports received by us and on information provided by the reporting persons, we believe that, during the fiscal year ended December 31, 2011, our directors, officers and owners of more than 10% of our common stock complied with all applicable filing requirements, except that each of H. Fenwick Huss, Ross K. Ireland, William L. Marks, Balan Nair, Roy J. Nichols and James L. North, each filed a Form 4 report on January 13, 2012 disclosing the acquisition of dividend equivalent rights effective on each of February 17, 2011, May 12, 2011, August 11, 2011 and November 10, 2011 and the settlement of those dividend equivalent rights effective on December 31, 2011 for shares of common stock and cash. The dividend equivalent rights described above accrued on grants of restricted stock granted to each of Messrs. Ireland, Marks, Nair, Nichols and North and Dr. Huss on December 30, 2010 in accordance with the terms of the 2010 Directors Stock Option Plan and should have been reported at the time of each of the four accruals as should the settlement of the dividend equivalent rights, in each case by the filing of a Form 4.

AUDIT COMMITTEE REPORT

The Audit Committee assists the Board of Directors in fulfilling its oversight responsibilities relating to the accuracy and integrity of ADTRAN’s financial reporting. Our Board of Directors has adopted an Audit Committee Charter, which sets forth the responsibilities of the Audit Committee. A copy of the Audit Committee Charter is available on our website at www.adtran.com.

The Audit Committee held eight meetings during the fiscal year ended December 31, 2011. Representatives of PricewaterhouseCoopers LLP, our independent registered public accounting firm, attended each meeting. The Audit Committee reviewed and discussed with management and PricewaterhouseCoopers LLP our audited financial statements for the fiscal year ended December 31, 2011 and our unaudited quarterly financial statements for the quarters ended March 31, June 30 and September 30, 2011. The Audit Committee also discussed with PricewaterhouseCoopers LLP the matters required under Statement on Auditing Standards No. 61 and No. 90 (Codification of Statements on Auditing Standards, AU § 380), as amended or superseded.

In addition to the review of annual and interim financial statements, the Audit Committee continued its focus on functions and risks which could adversely impact ADTRAN’s financial position. Audit Committee meetings included overviews of the status of testing of key internal controls over financial reporting. The Audit Committee has actively reviewed management’s assessment of the effectiveness of ADTRAN’s internal control over financial reporting (including management’s evaluation of identified control deficiencies and management’s program for remediation of those deficiencies) and PricewaterhouseCoopers LLP’s report thereon, both of which are included in the Annual Report on Form 10-K for the year ended December 31, 2011.

The Audit Committee also received the written disclosures and the letter from PricewaterhouseCoopers LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding the communication of PricewaterhouseCoopers LLP with the Audit Committee concerning independence, and has discussed with PricewaterhouseCoopers LLP its independence. The Audit Committee reviewed the audit and non-audit services provided by PricewaterhouseCoopers LLP for the fiscal year ended December 31, 2011 and determined to engage PricewaterhouseCoopers LLP as the independent registered public accounting firm of ADTRAN for the fiscal year ending December 31, 2012.

Based upon the Audit Committee’s review of the audited financial statements and the discussions noted above, the Audit Committee recommended that the Board of Directors include the audited financial statements in our Annual Report on Form 10-K for the year ended December 31, 2011 for filing with the SEC.

PROPOSAL 2 – ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION

We believe that our compensation policies and procedures, which include the pay for performance components that have been described previously in this Proxy Statement, are strongly aligned with the long-term interests of our shareholders. This advisory Shareholder resolution is commonly known as “Say-on-Pay.” At the 2011 Annual Meeting of Stockholders, ADTRAN asked its stockholders to express a preference as to how often the stockholders should consider the Say-on-Pay resolution – every year, every two years or every three years. At the 2011 Annual Meeting, 39,828,172 shares voted in favor of holding the “say on pay” resolution every year, 3,307,603 shares voted in favor of holding the “say on pay” resolution every two years, 7,419,605 shares voted in favor of holding the “say on pay” resolution every three years and 5,229,892 shares expressed no preference. The Board determined to present this resolution for consideration annually. This resolution is included to provide shareholders the opportunity to endorse or not endorse our executive pay program and policies, and the compensation of our named executive officers, through the following advisory proposal:

“RESOLVED, that the shareholders approve the overall executive compensation policies and procedures employed by the Company as well as the compensation of the named executive officers, all as described in the Compensation Discussion and Analysis and the tabular disclosure regarding named executive officer compensation in this Proxy Statement.”

Because your vote is advisory, it will not be binding upon the Board or the Compensation Committee.

The Board of Directors unanimously recommends a vote “For” approval of the “Say-on-Pay” proposal.

PROPOSAL 3 — RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

The Audit Committee of our Board of Directors, in accordance with its charter and authority delegated to it by the Board, has appointed the firm of PricewaterhouseCoopers LLP to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2012, and the Board of Directors has directed that such appointment be submitted to our stockholders for ratification at the Annual Meeting. PricewaterhouseCoopers LLP has served as our independent registered public accounting firm since 1986 and is considered by our Audit Committee to be well qualified. If the stockholders do not ratify the appointment of PricewaterhouseCoopers LLP, the Audit Committee will reconsider the appointment.

Representatives of PricewaterhouseCoopers LLP will be present at the Annual Meeting and will have an opportunity to make a statement if they desire to do so. They also will be available to respond to appropriate questions from stockholders.

The Audit Committee of the Board of Directors and the Board unanimously recommend that the stockholders vote “FOR” the proposal to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm.

PRINCIPAL ACCOUNTANT FEES AND SERVICES

The aggregate fees and expenses included in the Audit category are fees and expenses billed for the fiscal years for the integrated audit of our annual financial statements and review of our interim financial statements and statutory and regulatory filings.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of the Independent Registered Public Accounting Firm

The Audit Committee has adopted a pre-approval policy that provides guidelines for the audit, audit-related, tax and other non-audit services that may be provided to us by PricewaterhouseCoopers LLP. The policy: (1) identifies the guiding principles that must be considered by the Audit Committee in approving services to ensure that PricewaterhouseCoopers LLP’s independence is not impaired; (2) describes the audit, audit-related, tax and other services that may be provided and the non-audit services that may not be performed; and (3) sets forth pre-approval requirements for all permitted services.

Under the policy, a schedule is presented annually to the Audit Committee outlining the types of audit-related, tax and other services (other than audit services) that are likely to be performed during the year. The Audit Committee, based upon the guidelines in the policy, selects the services from that schedule that will be generally pre-approved services and attaches the list as an appendix to the policy. The Audit Committee then sets an annual aggregate fee limitation for all of these generally pre-approved services. For fiscal year 2011, that limit was set at $60,000. Any fees for the generally pre-approved services that exceed this aggregate fee limit must be specifically pre-approved. In addition, any services not on the list of general pre-approved services must be specifically pre-approved.

Each member of the Audit Committee has been delegated the authority to provide any necessary specific pre-approval, in the event that the full Audit Committee is not available. Any member of the Audit Committee who provides specific pre-approval must report such approval to the Audit Committee at its next meeting. To ensure compliance with the policy, a detailed report outlining all fees incurred year-to-date for services provided by PricewaterhouseCoopers LLP is presented to the Audit Committee on a quarterly basis.
