PROXY STATEMENT

May 4, 2005

       This proxy statement, which was first mailed to shareholders on March 29, 2005, is furnished in connection with the solicitation by the Board of Directors of CTS Corporation of proxies to be voted at the Annual Meeting of Shareholders to be held on Wednesday, May 4, 2005. Following is important information in a question-and-answer format regarding the Annual Meeting and this proxy statement.

Q:	What may I vote on?
A:	The election of nominees to serve on the Board of Directors.
Q:	How does the Board recommend I vote?
A:	The Board recommends a vote FOR each of the nominees identified in this proxy statement.
Q:	How will voting on any other business be conducted?
A:	Although we do not know of any business to be considered at the 2005 Annual Meeting other than as described in this proxy statement, if any other business is properly presented at the Annual Meeting, your signed proxy card gives authority to Donald K. Schwanz, CTS’ Chairman, President and Chief Executive Officer, and Richard G. Cutter, CTS’ Vice President, General Counsel and Secretary, to vote on those matters at their discretion.
Q:	How many votes are needed for approval of each item?
A:	Assuming that at least a majority of shares are present, either in person or by proxy, at the Annual Meeting, the nine director-nominees receiving the most votes will be elected. Only votes cast for a nominee will be counted. Your proxy will be voted for the nine nominees unless it contains contrary instructions. Abstentions, broker non-votes and instructions on your proxy to withhold authority to vote for one or more of the nominees will result in those nominees receiving fewer votes.
Q:	Who is entitled to vote?
A:	Shareholders as of the close of business on March 18, 2005, (the “Record Date”) are entitled to vote at the Annual Meeting. As of the Record Date, 36,741,228 shares of CTS common stock were issued and outstanding. Every shareholder of common stock is entitled to one vote for each share of common stock held on the Record Date.
Q:	How do I vote?
A:	Please sign and date each proxy card you receive and return it at your earliest convenience in the prepaid envelope provided. If you return your signed proxy card but do not mark the boxes showing how you wish to vote, your shares will be voted FOR each of the nominees. If you returned your proxy card, you have the right to revoke your proxy or change your vote at any time before the meeting by: notifying CTS’ Secretary; returning a later-dated proxy card; or voting in person at the meeting.

Q.	How can I vote shares of stock that I hold under the CTS Corporation Retirement Savings Plan (the “401(k) Plan”)?
A.	JP Morgan Chase Bank, the 401(k) Plan Trustee (the “Trustee”), will vote the shares in your account according to your instructions. Follow the same procedures described above for voting shares. If you return your signed proxy card but do not mark the boxes showing how you wish to vote, your shares will be voted FOR each of the nominees. You may also change your instructions on how to vote your shares in the manner described above. You may give instructions or change instructions to the Trustee on how to vote your shares up until April 28, 2005. On that date, your instructions will be transmitted to the Trustee and cannot be changed. If you do not instruct the Trustee on how to vote your shares, the Trustee will vote your shares in the same proportion as the shares properly voted by other participants who hold shares under the 401(k) Plan.
Q:	What does it mean if I get more than one proxy card?
A:	It means you hold shares registered in more than one account. Please sign and return all proxy cards you receive to ensure that all your shares are voted.

A:	Georgeson Shareholder Communications, Inc. was hired by CTS to solicit votes for $5,500, plus reasonable expenses.

Q:	Other members of my household and I hold shares of CTS stock in street name and we received only one copy of the proxy statement and annual report. How can we receive additional copies of these materials?
A:	Under the Securities and Exchange Commission’s “householding” rules, a company or broker who provides notice may deliver a single copy of the proxy statement and annual report to shareholders who share an address unless a shareholder submits contrary instructions. If you would prefer to receive separate copies of these documents in the future, you may notify your broker, you may direct a written or oral request to CTS Corporation, Investor Relations, 905 West Boulevard North, Elkhart, Indiana 46514, (574) 293-7511 or you may send an e-mail to shareholder.services@ctscorp.com.

SECTION 16(a) BENEFICIAL

       Section 16(a) of the Securities Exchange Act of 1934 requires CTS’ directors, executive officers and certain persons who beneficially own more than 10% of CTS’ common stock to file with the Securities and Exchange Commission and the New York Stock Exchange initial reports of ownership and reports of changes in ownership of CTS common stock. Executive officers, directors and greater than 10% shareholders are required to furnish CTS with copies of all Section 16(a) reports they file.

      CTS Corporation prepares and files Section 16(a) reports on behalf of directors and executive officers. In 2004, however, CTS inadvertently failed to file on time a Form 4 on behalf of George Newhart, an executive officer of the corporation who has subsequently retired. A Form 4 was filed two days following the required two-day reporting period. The Form 4 reported that Mr. Newhart had declined to pay the purchase price for a grant of restricted stock, which would have vested on June 24, 2004, and thereby forfeited his right to the stock.

      Based solely on written representations from reporting persons and on our review of Section 16(a) reports provided by those persons, CTS believes that all other required Section 16(a) filings were completed in a timely manner with respect to 2004.

CERTAIN BUSINESS RELATIONSHIPS

       Jones Day is a law firm which CTS has retained for specific legal services, on a case-by-case basis, for over ten years. The fees paid by CTS to Jones Day during 2004 were approximately .01% of Jones Day’s gross revenues for 2004. Mr. Profusek, a director standing for re-election, is a partner in Jones Day. Mr. Profusek satisfies the independent director criteria under the New York Stock Exchange Corporate Governance Listing Standards and the CTS Corporation Corporate Governance Guidelines.

CTS does not have a formal policy concerning whether the Committee will consider director candidates recommended by shareholders. CTS did not receive any requests for the Committee to consider any director candidate. At this time, the Board of Directors does not believe a formal policy is necessary, because CTS’ bylaws provide a process for nomination of directors and no shareholder nominations for director have been received. The Committee will continue to monitor developments in this area and consider whether to adopt a formal policy on shareholder recommendation of director-nominees.

      The Committee reviews with the Board, on an annual basis, the requisite skills and director characteristics of new Board members as well as the composition of the Board as a whole. This review includes an assessment of whether each non-management director qualifies as independent and consideration of the diversity, age, skills and experience of the directors in the context of the needs of the Board. Although the Committee has not established any specific minimum criteria or qualifications that a candidate must possess, the Committee seeks candidates who possess the experience necessary to make a valuable contribution to the Board.

FURTHER INFORMATION CONCERNING THE BOARD OF DIRECTORS

       During 2004, the Board of Directors had seven meetings. In 2004, all of the directors attended all or substantially all of the meetings of the Board of Directors and the committees of which they were members and all satisfied the 75% attendance threshold specified in Securities and Exchange Commission rules. It is the policy of the Board of Directors that each director endeavor to attend the annual meeting of shareholders, unless exigent circumstances arise. Eight of the nine directors standing for re-election at the 2004 Annual Meeting attended the meeting.

      The Board of Directors has determined that each non-management director is an independent director and has no material relationship with CTS, apart from his or her service as a director. The independent directors are Walter S. Catlow, Lawrence J. Ciancia, Thomas G. Cody, Gerald H. Frieling, Jr., Roger R. Hemminghaus, Michael A. Henning, Robert A. Profusek, and Patricia K. Vincent. The Board of Directors made this determination by reference to the definition of an independent director contained in the New York Stock Exchange Corporate Governance Listing Standards and by reference to the standards set forth in the CTS Corporation Corporate Governance Guidelines. The CTS Corporation Corporate Governance Guidelines provide that an independent director is one who:

	•	Is not an employee of the corporation and has not been an employee of the corporation for at least five years;
	•	Is not an employee or affiliate of the corporation’s present auditing firm or an auditing firm retained by the corporation within the past five years and has not been an employee or affiliate of such a firm for at least five years;
	•	Is not an employee of a company on whose board an executive of the corporation presently serves as a director or has served as a director within the past five years and has not been an employee of such a company for at least five years;
	•	Is not an employee of a company that accounts for at least 2% or $1 million, whichever is greater, of the corporation’s consolidated gross revenues, and has not been an employee of such a company for at least five years;

Table of Contents

	•	Is not an employee of any company for which the corporation accounted for at least 2% or $1 million, whichever is greater, of the company’s consolidated gross revenues; and has not been an employee of such a company for at least five years;
	•	Is not an employee or director of any company that invests in or trades CTS stock or that advises investors concerning CTS stock;
	•	Does not presently receive any direct or material indirect compensation from the corporation other than the standard director’s compensation package;
	•	Has not received more than $100,000 per year in direct compensation from the company, excluding the standard director’s compensation package, during the past five years;
	•	Does not have any other relationship with the corporation or any other entity, including charitable and civic organizations that in the opinion of the Board could be considered to effect the director’s ability to exercise his independent judgment as a director;
	•	Is not an immediate family member of any individual who would fail to meet the criteria for independence set forth above.

      A copy of the Corporate Governance Guidelines may be obtained free of charge from the CTS Secretary upon request or from CTS’ Web site at http://www.ctscorp.com/governance/guidelines.htm.

      The CTS Corporate Governance Guidelines encourage all directors to participate in director continuing education programs. The corporation reimburses directors for attendance at such programs. In addition, management monitors and reports to the directors regarding significant corporate governance initiatives. The directors also receive a presentation on new developments in corporate governance no less frequently than annually.

      The Board of Directors has adopted CTS stock ownership guidelines that apply to non-employee directors and executives in order to align their interests with those of shareholders and promote enduring shareholder value. The guidelines are administered by the Compensation Committee. A copy of the guidelines may be obtained free of charge from CTS’ Secretary upon request.

      CTS has adopted a Code of Ethics that applies to all of its employees, including its principal executive officer, principal financial officer and principal accounting officer or controller. A copy of CTS Code of Ethics may be obtained free of charge from the CTS Secretary upon request or from CTS’ Web site at www.ctscorp.com/governance/code of ethics.htm.

      It is the policy of the Board of Directors to hold an executive session of non-management directors at each regular scheduled Board of Directors meeting. Chairmanship of the executive sessions is rotated among all non-management directors on an alphabetical basis.

      Shareholders may address written communications to individual directors, including non-management directors, or to the Board of Directors as a whole, in care of the CTS Secretary at CTS’ Corporate Office, 905 West Boulevard North, Elkhart, Indiana, 46514. Such communications must include the name and address of the shareholder, as they appear on the record books of CTS and the name and address of the beneficial owner, if any, on whose behalf the communication is submitted. The Secretary will compile such communications and forward them to the directors on a periodic basis. However, the Secretary has authority to disregard any communication which is primarily an advertisement or solicitation or which is threatening, obscene or similarly inappropriate in nature. Communications that have been disregarded for these reasons may be reviewed by any non-management director upon request.

DIRECTOR COMPENSATION

       Employee directors receive no additional compensation for serving on the Board of Directors or Board Committees. Non-employee directors receive the following fees for their service on the Board: annual board retainer — $24,000; annual retainer for each Audit Committee member — $4,000; annual retainer for each Finance, Nominating and Governance and Compensation Committee Member — $2,500; additional annual retainer for Audit Committee Chairman — $4,000; additional annual retainer for Compensation Committee Chairman — $3,000; additional annual retainer for Finance and Nominating and Governance Chairman — $2,000; meeting fee for each Board or Committee Meeting — $1,500. Effective in 2003, the Board adopted a policy providing that all committee meetings, including special meetings called by the committee chairman, are compensated at the regular meeting fee rate. Special activity by the committee chairman, as well as any special activity by another committee member that is requested or approved by the committee chairman, is also compensated at the regular meeting fee rate. Non-employee directors are reimbursed by the corporation for reasonable travel expenses related to their performance of services and for director education programs.

      In 1990, CTS adopted the CTS Corporation Stock Retirement Plan for Non-Employee Directors. Under that plan, a deferred stock unit account was established for each non-employee director. Through January 2004, 800 common stock units and additional units representing dividends on CTS common stock paid were credited annually to each non-employee director’s account. When a non-employee director retires from the Board, he or she receives one share of CTS common stock for each deferred stock unit credited to his or her account. On December 1, 2004, the Board of Directors amended the plan to preclude crediting any additional units to the deferred stock unit accounts. On December 1, 2004, each non-employee director received a grant of restricted stock units under the CTS Corporation 2004 Omnibus Long-term Incentive Plan equivalent to the number of deferred stock units which would have been credited to the director for 2004 service under the Stock Retirement Plan for Non-Employee Directors. Under the terms of this award, each non-employee director will receive one share of CTS common stock for each restricted stock unit upon retirement from the Board.

      In 2002, the Board established a $30,000 annual stock-based compensation target for each non-employee director. Through 2004, this target was achieved by calculating the value of the 800 common stock units to be credited under the CTS Corporation Stock Retirement Plan for Non-Employee Directors based on the closing price of CTS common stock on the New York Stock Exchange on the credit date. If the calculated value of the common stock units was less than $30,000, each non-employee director received a stock option award sufficient to make up the difference between that value and $30,000, based on the closing price of CTS common stock on the New York Stock Exchange on the credit date. For 2005, the stock-based compensation target was achieved by awarding each non-employee director 2,300 restricted stock units under the CTS Corporation 2004 Omnibus Long-term Incentive Plan. The awards were granted on December 1, 2004 and became distributable on January 11, 2005 absent a deferral election by the non-employee director. Upon distribution, one share of CTS common stock for each restricted stock unit is transferred to the non-employee director.

      Employment Agreement With Donald K. Schwanz. Mr. Schwanz has an employment agreement with CTS which provides that for five years beginning on October 1, 2001 (the “Term”), Mr. Schwanz will be employed by CTS as President and Chief Executive Officer, at an initial annual salary of $630,000. During the Term of the agreement, if Mr. Schwanz’s employment is terminated as a result of his death or disability, for good reason (as defined in the agreement) or by CTS without cause (as defined in the agreement), Mr. Schwanz will receive severance benefits equal to his then current annual salary for the remainder of the Term, plus an annual bonus for each year remaining in the Term equal to the largest cash and stock bonus that he received for any year during the Term, but no less than $330,000. In addition, if Mr. Schwanz’s employment is terminated by Mr. Schwanz for good reason or by CTS without cause, Mr. Schwanz may instead receive a lump sum equal to 3 1/3 times the sum of his then current annual salary and the largest cash and stock bonus that he received for any year during the Term, but no less than $330,000. Any payments to Mr. Schwanz upon a change in control are increased to compensate Mr. Schwanz for any excise tax payable by him pursuant to Section 280G of the Internal Revenue Code of 1986, as amended. The payments and benefits to Mr. Schwanz under his employment agreement are reduced automatically by any corresponding payments or benefits under his severance agreement described below.

      Mr. Schwanz’s employment agreement also provides for an enhanced pension benefit under which for every year of service he accrues after June 30, 2002, an extra year will be credited to him for pension calculation purposes.

      Change in Control Severance Agreements. Each of the Named Executive Officers has executed a severance agreement with CTS, which becomes operative only upon a change in control of CTS. The term of each agreement is automatically extended each January 1 unless notice is given otherwise. Severance benefits are provided if within three years of a change in control, a covered executive terminates his employment for good reason (as defined in the agreement) or his employment is terminated for any reason other than cause (as defined in the agreement), disability or death. Severance benefits include: (i) a lump sum equal to three times the sum of the greater of base salary at the time of the change in control or average base salary over the three years prior to termination plus the greater of average incentive pay over the three years prior to the change in control or target incentive pay for the year in which the change in control occurred; (ii) continued participation for 36 months following termination in welfare benefit plans and similar benefit programs; (iii) a lump sum payment equal to the increase in actuarial value of the benefits under CTS’ qualified and supplemental retirement plans that the executive would have received had he remained employed; (iv) a lump sum payment ($105,000 for Mr. Schwanz and $67,500 for the other Named Executive Officers) in lieu of any perquisites the executive would otherwise have been provided; (v) outplacement services; (vi) reimbursement of legal, tax and estate planning expense related to the severance agreement; (vii) reimbursement of relocation expenses incurred during the 36 month period following termination; (viii) a lump sum payment equal to target incentive pay for the year in which the termination occurs, prorated based on actual service during the year; and (ix) accelerated vesting, exercise rights and

STOCK OPTIONS

       The following table reflects information about stock options awarded to the Named Executive Officers in 2004. These stock options are exercisable in four substantially equal annual installments commencing on June 9, 2005, in accordance with the terms set forth in the stock option agreements. Upon termination of employment due to death or total and permanent disability, the option would continue to vest on its schedule and would be exercisable for one year following the termination date. Upon termination of employment due to qualified retirement (as defined in the stock option agreements), the option would continue to vest on its schedule and would be exercisable for one year following the date on which the final installment becomes exercisable. Upon termination of employment for any other reason, the option would be exercisable within the three month period following the termination date, but only to the extent vested as of the termination date.

Option Grants in Last Fiscal Year

(1)

Potential realizable value is determined by assuming an initial value equal to the option price per share, the market closing price for CTS common stock on the date of grant, and applying the stated annual appreciation rate compounded annually for the remaining term of the option, subtracting the exercise price and multiplying the remainder by the number of shares subject to options granted. Actual gains, if any, on stock option exercises are dependent on the future performance of the common stock and overall stock market conditions.

PENSION PLAN

       The following table shows the estimated annualized retirement benefits payable to a covered participant in the CTS Corporation Pension Plan (the “Plan”) who is a salaried employee. The benefit formula is calculated as 1.25% of average monthly pay during the highest three calendar years of a participant’s last ten calendar years of service, multiplied by a participant’s credited service to arrive at the annualized benefit below.

Pension Plan Table

      Covered compensation is essentially equal to the salary and bonus columns in the Summary Compensation Table, together with the cash payments received in connection with the lapse of transfer restrictions on restricted shares as described in footnote (3) to the Summary Compensation Table. These benefits are not subject to any deduction for social security or other offsets. The years of service credited to the Named Executive Officers as of December 31, 2004 are: Donald K. Schwanz — 4.56 years; Vinod M. Khilnani — 3.78 years; Donald R. Schroeder — 32.44 years; James L. Cummins — 27.78 years; and Richard G. Cutter — 5.56 years.

      Section 415 of the Internal Revenue Code of 1986, as amended (the “Code”), generally places a limit of $165,000 on the amount of annual pension benefits that may be paid from the Plan. Section 401(a)(17) of the Code limits the amount of annual compensation that may be taken into account in calculating a benefit under the Plan to $205,000. The Plan includes a supplemental benefit for named participants that allows for payment of benefit amounts, to the extent permitted by the Code in excess of the benefit amounts that would be permitted by those provisions. Each of the Named Executive Officers also participates in an unfunded supplemental retirement plan adopted in 2003 that provides that the participant will receive a benefit equal to the difference between his actual benefit

All members of the Audit Committee are financially literate and independent as defined in the New York Stock Exchange Corporate Governance Listing Standards.

      The Audit Committee has reviewed and discussed with CTS management and PricewaterhouseCoopers LLP (“PwC”), CTS’ independent auditor, the audited consolidated financial statements of the Company for 2004; has discussed with PwC the matters required to be discussed by Statement on Auditing Standards No. 61; has received from the independent auditor the written disclosures and letter required by Independence Standards Board Standard No. 1; and has discussed with the independent auditor the auditor’s independence. Based on the review and discussions described above, the Audit Committee recommended to the Board of Directors that the financial statements be included in CTS’ Annual Report on Form 10-K for the fiscal year ended December 31, 2004, for filing with the Securities and Exchange Commission.

CTS CORPORATION 2004 AUDIT COMMITTEE

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

       PwC is CTS’ independent registered public accounting firm. PwC representatives will attend the Annual Meeting to be available to respond to appropriate questions by shareholders and to have the opportunity to make statements, if they desire.

      The following table presents fees for professional audit services and other services provided by PwC to CTS for the years ended December 31, 2003 and December 31, 2004. The Audit Committee’s policy is to pre-approve all audit and non-audit services provided by the independent registered public accounting firm. The Audit Committee annually reviews audit and non-audit services proposed to be rendered by PwC during the fiscal year. The Audit Committee has delegated authority to the Audit Committee Chairman to grant pre-approval of services by the independent registered public accounting firm, provided that the Chairman reports on any such pre-approval decisions at the next scheduled meeting of the Audit Committee. None of the services rendered by PwC were approved by the Audit Committee after the services were rendered pursuant to the de minimis exception established under the rules of the Securities and Exchange Commission.

COMPENSATION COMMITTEE INTERLOCKS

       Directors Catlow, Cody, Hemminghaus, Profusek and Vincent served as members of the Compensation Committee during 2004. Mr. Profusek is a partner in Jones Day, a law firm which CTS has retained for specific legal services on a case-by-case basis for over ten years. During 2004, no executive officer of CTS served as a director of any other entity for which any CTS director was an executive officer. Each member of the Compensation Committee is an independent director under the New York Stock Exchange Corporate Governance Listing Standards and the CTS Corporation Corporate Governance Guidelines.

REPORT OF THE COMPENSATION COMMITTEE

       The Committee’s Responsibilities: The Compensation Committee of the Board has responsibility for setting and administering CTS’ executive compensation policies. The Committee is composed entirely of independent directors. Reports of the Committee’s actions and decisions are presented to the full Board. The purpose of this report is to summarize the principles, specific program objectives and other factors considered by the Committee in reaching its determinations regarding executive compensation.

      Compensation Philosophy: The Committee has implemented executive compensation programs which are intended to:

	•	Encourage strong financial and operational performance of CTS;
	•	Link compensation to the interests of shareholders;
	•	Emphasize performance-based compensation; and
	•	Provide a competitive level of total compensation necessary to attract and retain talented and experienced executives.

18

Table of Contents

      Compensation Methodology: The Committee believes that CTS’ executive compensation programs reflect this philosophy and provide executives with strong incentives to maximize CTS’ performance and enhance shareholder value. The executive compensation programs consist of both annual and long-term components and include performance-based and equity-based components. Historically, the Committee has reviewed market data and assesses CTS’ competitive position in the area of executive compensation. CTS also retains independent compensation and benefits consultants to assist in evaluating executive compensation programs. The Committee uses an independent consultant to provide additional assurance that CTS’ executive compensation programs are reasonable and appropriate.

	•	Base Salary: Annual base salary is designed to compensate CTS executives for their qualifications, responsibilities and performance. The Committee’s objective is to compensate executives at approximately the fiftieth percentile of base salaries paid for similar positions at similarly situated companies.
	•	Annual Incentives: CTS has maintained an annual management incentive plan for a number of years that provides cash compensation incentives based on the financial performance of CTS. The Committee establishes the performance measures and approves the payouts under the plan for each executive officer. Under the 2004 Management Incentive Plan, the committee established specific financial objectives based on CTS’ sales, CTS’ earnings per share (“EPS”) and/or the contribution to EPS of specific business units. For 2004, CTS achieved the established sales and EPS targets and certain business units achieved their established contribution to EPS targets. Each of the executive officers qualified for a bonus under the terms of the 2004 Management Incentive Plan.
	•	Long-Term, Stock-Based Compensation: CTS historically used two forms of long-term, stock-based incentives, restricted stock grants and stock options, under shareholder-approved plans. In 2004, CTS introduced a new form of equity compensation, restricted stock unit grants, under the shareholder-approved CTS Corporation Omnibus Long-term Incentive Plan. The Committee believes that stock ownership and stock-based compensation are valuable tools for motivating employees to improve the long-term performance of CTS. The Committee also believes that they are the best way to tie a significant amount of an executive’s potential income to enhanced shareholder value. CTS’ stock compensation plans have change of control provisions under which, upon a change of control of CTS, benefits thereunder accelerate and vest immediately.

The Committee has generally awarded stock options that provide for a purchase price equal to market value of the stock on the date of the grant and which vest over a four-year period. During 2004, the Committee granted options for a total of 79,400 shares to the Named Executive Officers, as described in the chart entitled “Option Grants in Last Fiscal Year” on page 15 of this proxy statement. In 2004, the Committee began using awards of restricted stock units in place of restricted stock. These awards distribute to the recipient one share of CTS common stock for each unit upon vesting. Most of these awards vest in installments over five years. To recognize significant individual contributions, the Committee may grant individual awards using alternative vesting schedules or distribution options. In 2004, the Committee granted a total of 103,500 restricted stock units to Named Executive Officers, as described in the “Summary Compensation Table” on page 13 of this proxy statement. The Committee has followed the recent debate concerning the equity-linked compensation practices of publicly-traded companies and intends to continue to focus on developments in this area.

      Compensation for the Chief Executive Officer (“CEO”): The Committee annually reviews and makes recommendations to the Board of Directors regarding the CEO’s compensation. Using surveys and other available compensation data, the Committee strives to establish a base salary range for the

      Deductibility of Certain Executive Compensation: Federal income tax law caps at $1,000,000 the deductible compensation per year for each of the Named Executive Officers in the proxy statement, subject to certain exceptions. In developing and implementing executive compensation policies and programs, the Compensation Committee considers whether particular payments and awards are deductible for federal income tax purposes, along with other relevant factors. Consistent with this policy, the Committee has taken what it believes to be appropriate steps to maximize the deductibility of executive compensation. While it is the general intention of the Committee to meet the requirements for deductibility, the Committee may approve payment of non-deductible compensation from time to time if circumstances warrant. The Committee will continue to review and monitor its policy with respect to the deductibility of compensation.
