Dear Fellow Stockholder:
 
You have now received your proxy materials for the California Water Service Group’s 2010 Annual Meeting of Stockholders.
 
If your shares are held in the name of your brokerage firm, due to a recent change in New York Stock Exchange (NYSE) rules, your broker can no longer vote your shares for the election of directors without instructions from you. If you do not provide voting instructions to your broker, no votes will be cast on your behalf in the election of directors.
 
If your shares are held in the name of your brokerage firm, you should have received with the proxy materials instructions from your broker that you must follow in order for your shares to be voted. We urge you to review the instructions from your broker as soon as possible. If your shares are held in your own name, please follow the voting instructions included on the enclosed proxy card.
 
Your vote is important to us. Thank you for your investment in the California Water Service Group.
 
Sincerely,
 
/s/  Robert W. Foy

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE
STOCKHOLDERS MEETING TO BE HELD ON MAY 25, 2010
 
Electronic copies of the Group’s 10-K, including exhibits, and this Proxy Statement will be available on the Group’s website at: http://www.calwatergroup.com.
 
QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND THE ANNUAL MEETING
 
What am I voting on?
 
  •  Election of nine directors to serve until the 2011 Annual Meeting.
 
  •  Ratification of the Audit Committee’s selection of Deloitte & Touche LLP as the Group’s independent registered public accounting firm for 2010.
 
Those elected to serve as directors of California Water Service Group, which we refer to in this Proxy Statement as the Group, will also serve as the directors of California Water Service Company and CWS Utility Services, two of the Group’s operating subsidiaries.
 
Who may attend the Annual Meeting?
 
All Group stockholders may attend.
 
Who is entitled to vote?
 
Stockholders of record at the close of business on March 31, 2010 (the “Record Date”), or those with a valid proxy from a brokerage firm or another similar organization that held shares on the Record Date.
 
How many votes do I get?
 
Each share of common stock is entitled to one vote. You may also use “cumulative voting” in the election of directors as described below.
 
What is “cumulative voting” and how does it work?
 
You may elect to “cumulate” your vote in the election of directors. Cumulative voting permits you to allocate among the director nominees the total number of votes you may cumulate.
 
If you hold common stock, the total number of votes you may cumulate is determined by multiplying the number of shares you hold by the number of director positions to be filled. For example, if you own 100 shares of common stock, you may distribute 900 “FOR” votes (100 shares x 9 director positions to be filled) among as few or as many of the nine director nominees as you choose.
 
If you wish to cumulate your vote for director nominees, you must follow the special instructions on the proxy card or voting instruction card and vote by mail. If you do not indicate otherwise, the proxies may use their discretion to cumulate votes.
 
How are the directors elected?
 
The nine nominees receiving the highest number of votes are elected to the Board.
 
Who are the Board’s nominees?
 
The nominees are Douglas M. Brown, Robert W. Foy, Edwin A. Guiles, Edward D. Harris, Jr., M.D., Bonnie G. Hill, Richard P. Magnuson, Linda R. Meier, Peter C. Nelson, and George A. Vera. All the nominees are current Board members. See “Proposal No. 1 — Election of Directors” for biographical information and qualifications, including the nominees’ current directorships in other publicly held companies.

What is the required vote for the second proposal to pass?
 
In order for the Board’s selection of Deloitte & Touche LLP as independent registered public accounting firm to be ratified, the proposal must receive the affirmative vote of a majority of the shares present in person or represented by proxy and entitled to vote at the meeting.
 
How do I vote?
 
You may vote on the Internet.
 
You do this by following the “Vote by Internet” instructions on the proxy card. If you vote on the Internet, you do not have to mail in your proxy card.
 
You may vote by telephone.
 
You do this by following the “Vote by Telephone” instructions on the proxy card. If you vote by telephone, you do not have to mail in your proxy card. You must have a Touch-Tone phone to vote by telephone.
 
You may vote by mail.
 
You do this by signing the proxy card and mailing it in the enclosed, prepaid and addressed envelope. If you mark your voting instructions on the proxy card, your shares will be voted as you instruct.
 
You may vote in person at the meeting.
 
We will hand out written ballots to anyone who wants to vote at the meeting. If you hold your shares in street name, you must request a legal proxy from your stockbroker in order to vote at the meeting.
 
If you return a signed card but do not provide voting instructions, your shares will be voted:
 
  •  for the nine named director nominees, and
 
  •  for the ratification of the selection of the independent registered public accounting firm.
 
We have been advised by legal counsel that these telephone and Internet voting procedures comply with Delaware law.
 
What if I change my mind after I return my proxy?
 
You may revoke your proxy any time before the polls close at the meeting. You may do this by:
 
  •  signing another proxy with a later date;
 
  •  voting on the Internet or by telephone (your latest Internet or telephone proxy is counted);
 
  •  voting again at the meeting; or
 
  •  notifying the Corporate Secretary, in writing, that you wish to revoke your previous proxy. We must receive your notice prior to the vote at the Annual Meeting.
 
Will my shares be voted if I do not return my proxy?
 
If you are a stockholder of record (that is, you hold your shares in your own name), and you do not return your proxy, your shares will not be voted unless you attend the meeting and vote in person. Different rules apply if your stockbroker holds your shares for you.
 
What happens if my shares are held by my stockbroker?
 
If you do not return your proxy, then your stockbroker, under certain circumstances, may vote your shares.
 
Stockbrokers must write to you asking how you want your shares voted. If you do not respond, stockbrokers have authority under exchange regulations to vote your uninstructed shares on certain “routine” matters, including ratification of the selection of the independent registered public accounting firm. Effective January 1, 2010,

however, the election of directors is no longer considered a “routine” matter. Thus, if you do not instruct your stockbroker on how to vote in the election of directors, no votes will be cast on your behalf. If you wish to change the voting instructions you gave to your stockbroker, you must ask your stockbroker how to do so.
 
If you do not give your stockbroker voting instructions, the stockbroker may either:
 
  •  proceed to vote your shares on routine matters and refrain from voting on nonroutine matters; or
 
  •  leave your shares entirely unvoted.
 
Shares that your stockbroker does not vote (“stockbroker non-votes”) will count towards the quorum only. We encourage you to provide your voting instructions to your stockbroker. This ensures that your shares will be voted at the meeting.
 
You may have granted to your stockbroker discretionary voting authority over your account. If so, your stockbroker may be able to vote your shares even on nonroutine matters, depending on the terms of the agreement you have with your stockbroker.
 
What happens if I abstain from voting on a proposal?
 
If you abstain from voting on a proposal (other than the election of directors), either by proxy or in person at the Annual Meeting, your shares will be counted in determining whether we have a quorum, but the abstention will have the same effect as a vote against the proposal. Abstentions have no effect on the election of directors.
 
Who will count the vote?
 
Representatives of Broadridge Financial Services, Proxy Services, will serve as the inspector of elections and count the votes.
 
What does it mean if I get more than one proxy card?
 
It means that you have multiple accounts at the transfer agent and/or with stockbrokers. Please sign and return all proxy cards to ensure that all your shares are voted.
 
What constitutes a quorum?
 
A majority of the outstanding shares — present at the Annual Meeting or represented by persons holding valid proxies — constitutes a quorum. If you submit a valid proxy card, your shares will be part of the quorum.
 
Without a quorum, no business may be transacted at the Annual Meeting. However, whether or not a quorum exists, a majority of the voting power of those present at the Annual Meeting may adjourn the Annual Meeting to another date, time and place.
 
At the Record Date, there were approximately 2,596 stockholders of record. There were 20,803,738 shares of our common stock outstanding and entitled to vote at the Annual Meeting.
 
What percentage of stock do the directors and executive officers own?
 
Together, they own one percent of our common stock. See “Stock Ownership of Management and Certain Beneficial Owners” for more details.
 
Who are the largest common stockholders?
 
As of April 7, 2010, the largest principal stockholder was BlackRock, Inc, which held 1,195,191 shares of common stock, representing 5.76% of our aggregate outstanding stock. SJW Corp. held 1,099,952 shares of common stock, representing 5.3% of our aggregate outstanding common stock. To the best of our knowledge, no other stockholders held over 5% of our common shares.

What is the deadline for submitting stockholder proposals for the Group’s proxy materials for next year’s Annual Meeting?
 
Any proposals that stockholders intend to submit for inclusion in the Group’s 2011 proxy materials must be received by the Corporate Secretary of the Group by December 9, 2010. A proposal and any supporting statement together may not exceed 500 words. Please submit the proposal to the Corporate Secretary, California Water Service Group, 1720 North First Street, San Jose, California 95112-4598.
 
How can a stockholder propose a nominee for the Board or other business for consideration at a stockholders’ meeting?
 
Any stockholder of record who is entitled to vote at a stockholders’ meeting may propose a nominee for the Board or propose other business for consideration at the meeting. The bylaws contain the requirements for doing so. Contact the Corporate Secretary to request a copy of the full bylaw requirements. Briefly, a stockholder must give timely prior notice of the matter to the Group. The notice must be received by the Corporate Secretary at the Group’s principal place of business by the 150th day before the first anniversary of the prior year’s Annual Meeting. For the 2011 Annual Meeting, to be timely, notice must be received by the Corporate Secretary by December 27, 2010. If we move the date of the meeting by more than thirty days before or more than sixty days after the date of the previous meeting, notice is due by the 150th day before the Annual Meeting or the 10th day after we publicly announce the holding of the meeting. If the Group’s Corporate Secretary receives notice of a matter after the applicable deadline, the notice will be considered untimely, and the persons named as proxies may exercise their discretion in voting with respect to the matter when and if it is raised at the meeting.
 
The bylaws specify what the notice must contain. Stockholders must comply with all requirements of the securities laws with respect to matters submitted in accordance with the bylaws. The bylaws do not affect any stockholder’s right to request inclusion of proposals in the Group’s Proxy Statement under the rules of the Securities and Exchange Commission.
 
How can a stockholder or other interested party contact the independent directors, the director who chairs the Board’s executive sessions or the full Board?
 
Stockholders or other interested parties may address inquiries to any of the Group’s directors, to the director who chairs the Board’s executive sessions, or to the full Board, by writing to the Corporate Secretary, California Water Service Group, 1720 North First Street, San Jose, California 95112-4598. All such communications are sent directly to the intended recipient.
 
Can I make comments and/or ask questions during the Annual Meeting?
 
Yes, most certainly. Stockholders wishing to address the meeting are welcome to do so by adhering to the following guidelines:
 
1. Stockholders may address the meeting when recognized by the Chairman or President and Chief Executive Officer.
 
2. Each stockholder, when recognized, should stand and identify himself or herself.
 
3. Stockholder remarks must be limited to matters before the meeting and may not exceed two minutes in duration per speaker. No cameras, video or recording equipment will be permitted at the meeting.
 
BOARD STRUCTURE
 
This section briefly describes the structure of the Board and the functions of the principal committees of the Board. The Board has adopted Corporate Governance Guidelines that, along with the charters of the Board committees, provide a framework for the governance of the Group. The Corporate Governance Guidelines and the charters for the Audit, Organization and Compensation, Finance and Risk Management, Nominating/Corporate Governance and Executive committees are posted on the Group’s website at http://www.calwatergroup.com. These

Table of Contents

documents are also available in written form upon request to the Corporate Secretary, California Water Service Group, 1720 North First Street, San Jose, California 95112-4598.
 
The Group’s policy is that all directors must be able to devote the required time to carry out director responsibilities and should attend all meetings of the Board and of committees on which they sit.
 
Leadership Structure
 
The role of chairman of the Board and the role of chief executive officer (CEO) are separate pursuant to the Corporate Governance Guidelines. The Corporate Governance Guidelines also provide for an independent lead director to further strengthen the governance structure. Mr. Douglas A. Brown currently serves as lead director. The lead director presides over executive sessions of the non-management and independent directors and has the authority to call executive sessions. The Board believes that this leadership structure fosters clear accountability, effective decision making and helps to ensure proper risk oversight for the Group.
 
Risk Oversight
 
Under the Corporate Governance Guidelines, the full Board oversees the Group’s processes for assessing and managing risk. The Board does not view risk in isolation but considers risk as part of its regular consideration of business decisions and business strategy. The Board exercises its risk oversight function through the Board as a whole and through its committees. Each of the Board committees considers the risks within its areas of responsibility and identified in its charter. The Finance and Risk Management Committee reviews the Group’s major risk exposures and the steps management has taken and proposes to take to monitor and control such exposures. The Audit Committee reviews with management risks related to financial reporting and internal controls. At least annually, the Finance and Risk Management Committee discusses the Group’s risk assessment and risk management with the Audit Committee. The Organization and Compensation Committee reviews enterprise risks to ensure that our compensation plans and programs do not encourage management to take unreasonable risks relating to our business. The Nominating/Corporate Governance Committee oversees risks related to matters of corporate governance, including director independence and board performance.
 
The Group has an Enterprise Risk Management Committee (ERMC) which reports directly to the Finance and Risk Management Committee. The ERMC is not a committee of the Board. The ERMC is chaired by the Group’s chief financial officer, and four other officers from various functions are members. The ERMC identifies and prioritizes key risks and recommends the implementation of appropriate mitigation measures, as needed. The ERMC meets at least semi-annually and reports regularly to the Finance and Risk Management Committee and the CEO. The ERMC reports to the Audit Committee no less frequently than annually. Further review or reporting on risks is conducted as needed or as requested by the Board or committee.
 
Committees:
 
AUDIT:  Reviews the Group’s auditing, accounting, financial reporting and internal audit functions. Also, the Committee is directly responsible for the appointment, compensation and oversight of the independent registered public accounting firm, although stockholders are asked to ratify the Committee’s selection that was adopted by the Board. All members are independent as defined in the listing standards of the New York Stock Exchange and meet the additional independence requirements for audit committee members imposed by the Sarbanes-Oxley Act and the rules of the SEC thereunder.
 
The Board has determined that George A. Vera, chair of the Audit Committee, is an audit committee financial expert and is independent as defined in the rules of the SEC and in the listing standards of the New York Stock Exchange. This means that the Board believes Mr. Vera has:
 
(i) an understanding of generally accepted accounting principles and financial statements;
 
(ii) the ability to assess the general application of such principles in connection with the accounting for estimates, accruals and reserves;


6


Table of Contents

(iii) experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the Group’s financial statements, or experience actively supervising one or more persons engaged in such activities;
 
(iv) an understanding of internal control over financial reporting; and
 
(v) an understanding of Audit Committee functions.
 
Designation of a person as an audit committee financial expert does not result in the person being deemed an expert for any purpose, including under Section 11 of the Securities Act of 1933. The designation does not impose on the person any duties, obligations or liability greater than those imposed on any other audit committee member or any other Director and does not affect the duties, obligations or liability of any other member of the Audit Committee or Board of Directors.
 
ORGANIZATION AND COMPENSATION:  Reviews the Group’s executive and director compensation, employee benefit plans and programs, including their establishment, modification and administration. All members are independent as defined in the listing standards of the New York Stock Exchange. In 2009, the Organization and Compensation Committee took steps to analyze the current risk profile of the Group’s executive and broad-based compensation programs. In its evaluation, the Organization and Compensation Committee review took into account the fact that the Group does not provide for cash-based annual incentive compensation and that Group operates in a highly regulated environment and thus maintains strong internal controls, which factors tend to mitigate against undue risk.
 
For a description of the processes and procedures used by the Organization and Compensation Committee for the consideration and determination of executive and director compensation, see “Compensation Discussion & Analysis” elsewhere in this Proxy Statement.
 
FINANCE AND RISK MANAGEMENT:  Assists the Board in reviewing the Group’s financial policies, risk management strategies and capital structure. All members are independent as defined in the listing standards of the New York Stock Exchange.
 
NOMINATING/CORPORATE GOVERNANCE:  Assists the Board by (i) identifying candidates and nominating individuals qualified to become Board members and (ii) developing and recommending a set of corporate governance principles applicable to the Group. All members are independent as defined in the listing standards of the New York Stock Exchange.
 
EXECUTIVE:  Has limited powers to act on behalf of the Board whenever it is not in session. This committee meets only as needed. The committee consists of a majority of independent directors.
 
During 2009, there were eight regular meetings of the Board, five meetings of the Audit Committee, two meetings of the Organization and Compensation Committee, two meetings of the Finance and Risk Management Committee, and two meetings of the Nominating/Corporate Governance Committee. Each of the director-nominees who served on the Board of California Water Service Group in 2009 attended at least 95% of all Board and applicable committee meetings. Collectively, they attended an average of 99% of all of the Board and applicable committee meetings.
 
Independence of Directors
 
As discussed in the Group’s Corporate Governance Guidelines, a substantial majority of the Board is made up of independent directors. Under the listing standards of the New York Stock Exchange, a director is independent if he or she has no material relationship, whether commercial, industrial, banking, consulting, accounting, legal, charitable or familial, with the Group, either directly or indirectly as a partner, stockholder or officer of an entity that has a material relationship with the Group. The Board makes an affirmative determination regarding the independence of each director annually, based on the recommendation of the Nominating/Corporate Governance Committee. The Board has adopted standards to assist it in assessing the independence of directors, which are set

Table of Contents

forth in the Corporate Governance Guidelines. Under these standards, the Board has determined that a director is not independent if:
 
  •  the director has a material relationship (including, among others, commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships) with companies that comprise the Group;
 
  •  the director is, or has been within the last three years, an employee of any company that comprises the Group or an immediate family member is, or has been within the last three years, an executive officer of any company that comprises the Group;
 
  •  the director or any immediate family member has received personally during any twelve-month period within the past three years more than $120,000 in direct compensation from companies that comprise the Group, other than director or committee fees and pension or other forms of deferred compensation for prior service (compensation received by an immediate family member for service as an employee, other than an executive officer, of the Group is not considered for purposes of this standard);
 
  •  the director or an immediate family member is a current partner of the Group’s external auditor; the director is a current employee of such a firm; the director’s immediate family member is a current employee of such a firm who works personally on the Group’s audit or the director or an immediate family member was in the last three years a partner or employee of such a firm and personally worked on the Group’s audit within that time;
 
  •  employment of the director or of an immediate family member within the last three years as an executive officer of a company whose Organization and Compensation Committee includes or included at the same time an executive officer of the Group;
 
  •  being an employee or having an immediate family member who is an executive officer of a customer or vendor or other party that has made payments to or received payments from companies that comprise the Group for property or services in an amount that exceeded the greater of 2% or $1 million of the party’s consolidated gross revenues, in any of the past three years; and
 
  •  the director, or the director’s spouse, is an executive officer of a non-profit organization to which the Group makes, or in the past three years has made, payments that, in any single fiscal year, exceeded the greater of 2% or $1 million of the non-profit organization’s consolidated gross revenues.
 
The Board has determined that none of the following relationships, in itself, is a material relationship that would impair a director’s independence:
 
  •  being a residential customer of any companies that comprise Group;
 
  •  being an executive officer or employee, or being otherwise affiliated with, a commercial customer from which the Group’s consolidated gross revenues in any of the last three years are or were not more than the greater of (i) 1% of the Group’s consolidated gross revenues for the year or (ii) $500,000;
 
  •  being an executive officer or employee of a supplier or vendor that has or had consolidated gross revenues from the Group in any of the last three years of not more than the lesser of (i) 1% of the Group’s consolidated gross revenues for the year or (ii) $500,000;
 
  •  having a 5% or greater ownership interest or similar financial interest in a supplier or vendor that has or had consolidated gross revenues from the Group in any of the last three years of not more than the lesser of (i) 1% of the Group’s consolidated gross revenues for such year or (ii) $500,000; and
 
  •  being a director of any of the Group’s subsidiaries.
 
Director Qualifications and Diversity
 
The Group seeks directors having the following specific qualifications:
 
  •  evidence of leadership in his or her particular field;
 
  •  broad experience and sound business judgment;


8


Table of Contents

 
  •  expertise in an area of importance to the Group and its subsidiaries;
 
  •  the ability to work in a collegial Board environment;
 
  •  high personal and professional ethics and integrity;
 
  •  the ability to devote the required time to carry out director responsibilities;
 
  •  the ability and willingness to contribute special competencies to Board activities, including appointment to Board committees;
 
  •  freedom from conflicts of interest that would interfere with serving and acting in the best interests of the Group and its stockholders;
 
  •  evidence of being a high caliber individual who has achieved a level of prominence in his or her career; for example, a CEO or highest level financial officer of a sizeable organization, a director of a major corporation, a prominent civic or academic leader, etc.
 
Additionally, Section 2.8 of the Group’s bylaws contains requirements that a person must meet to avoid conflicts of interest that would disqualify that person from serving as a director.
 
Board membership should reflect diversity in its broadest sense. The Group seeks directors who represent a diversity of backgrounds and experiences that will enhance the quality of the Board’s deliberations and decisions. The Board, as a whole, should possess a combination of skills, professional experience and backgrounds necessary to oversee the Group’s business.
 
Identification of Director Nominees
 
The Group identifies new director candidates by director recommendations and by the use of search firms selected by the Nominating/Corporate Governance Committee.
 
The Group considers nominees of stockholders in the same manner as all other nominees. The Group will consider director nominees recommended by stockholders who adhere to the procedure described under “Questions and Answers About the Proxy Materials and the Annual Meeting — How can a stockholder propose a nominee for the Board or other business for consideration at a stockholders’ meeting?” elsewhere in this Proxy Statement.
 
Executive Sessions of the Board
 
Under the Group’s Corporate Governance Guidelines, the nonmanagement directors meet at least four times each year in executive session without management present, and the independent directors meet in executive session at least once a year. The lead director, Mr. Douglas M. Brown, chairs these sessions. The lead director performs other responsibilities that are described in the Group’s Corporate Governance Guidelines.

COMPENSATION DISCUSSION AND ANALYSIS
 
The Organization and Compensation Committee (Committee) administers the Group’s compensation plans and programs for board members and executive officers. After a review of compensation levels, the Committee recommends to the full Board of Directors compensation levels, including the equity incentive plan awards for board members and executive officers for the 12-month period beginning January 1st of each year. The Committee starts its planning and review process in September of each year and typically concludes its process in November. The Group’s principal executive officer, principal financial officer, and three other most highly compensated executive officers in a particular year are referred to herein as “executive officers” or “executives.” More information on the committee and related charter can be found at the Group’s website at http://www.calwatergroup.com in the corporate governance section.
 
Compensation Philosophy for Executive Officers
 
The Group’s overall philosophy is to provide compensation that attracts, retains, and motivates talented executives, rewards excellent job performance and overall leadership, and provides for fair, reasonable, and competitive total compensation. The Committee believes that compensating executives using these criteria is a benefit to both stockholders and customers.

Table of Contents

Elements of Compensation
 
The material elements of the Group’s executive compensation program include:
 
  •  Salary
 
  •  Equity Compensation
 
  •  Basic and Supplemental Pension Plan Benefits
 
  •  Deferred Compensation Plan Benefits
 
  •  Limited Perquisites
 
Historically, the Group has not used annual bonuses as a compensation mechanism and did not use annual bonuses for the 2009 fiscal year. The Committee is mindful that as a holding company for a California regulated utility, the Group’s financial performance is to a large extent dependent upon California Public Utilities Commission (CPUC) ratemaking decisions and other factors beyond the control of the executives. Therefore, the Committee’s decisions regarding overall compensation are determined largely by its comparisons with peer groups and evaluation of factors that are within the executives’ control.
 
Salary
 
The Group provides a significant portion of executive officers’ total compensation in the form of base salaries. Base salaries provide a measure of security that enables executive officers to meet daily living expenses and financial commitments. The Committee reviews base salaries for executive officers annually and determines whether or not to recommend adjustments to base salaries. To assist the Committee in this review, the Group’s chief executive officer (CEO) provides an assessment of performance and recommendations regarding base salary adjustments to the Committee for each of the executive officers other than himself based on the competitive data and the other factors described below under “Determining Executive Compensation.”
 
As noted below, under “Determining Executive Compensation,” the Committee targets base salaries for each executive that are within the competitive range (defined as plus or minus 20% from the median compensation level) for the executive’s position as established by reference to the competitive data described below. As noted above, the Group does not pay annual cash incentive compensation. However, because annual incentives are a common component of executive compensation in the surveys included in the competitive data, the Group compares base salary levels for the executives to the actual total cash compensation (base salary plus actual bonus) for similar positions within the competitive data (rather than comparing the executive’s base salaries to the base salaries within the competitive data). Each of the executives’ base salaries for 2009 were within the competitive range of actual total cash compensation, except Mr. Ferraro whose base salary was slightly above the competitive range for his position because of his long tenure with the Group, his unique expertise and continued contributions in regulatory matters, and his corporate development responsibilities, each of which are greater than those usually afforded to executives in his position with other public utilities.
 
In addition to the review of competitive data, the CEO provides a full self-assessment of his own performance and degree of success in meeting the goals set for him by the Committee at the beginning of the year, and this is followed by the Committee’s assessment of the Group’s performance and the CEO’s role in achieving that performance. The CEO’s goals for 2009 were to implement improvements in California regulation, to achieve budgeted earnings per share of $1.96 (the Group’s actual performance resulted in earnings per share of $1.95), and to achieve planned results in other corporate initiatives. The Committee then reviews and discusses the performance of each executive and the competitive data provided by Presidio Pay Advisors (PPA). Once reviewed and agreed

Table of Contents

upon, the Committee recommends to the full Board of Directors the base salaries for the executive officers (including the CEO). The following tables shows the base salaries for each executive for 2008, 2009 and 2010:
 
                         
Executive Officer
  2008 Base Salary     2009 Base Salary     2010 Base Salary  
 
Mr. Nelson
  $ 794,000     $ 875,000     $ 910,000  
Mr. Kropelnicki
  $ 370,000     $ 400,000     $ 425,000  
Mr. Ferraro
  $ 340,000     $ 375,000     $ 381,000  
Mr. Guzzetta
  $ 280,000     $ 295,000     $ 300,000  
Mr. Ekstrom
  $ 235,000     $ 260,000     $ 270,000  
 
Shown in the chart above for both 2009 and 2010, are the base salary increases for senior management approved by the Committee. These increases are intended to maintain base salaries within the competitive range of actual total cash compensation for similar positions within the competitive data.
 
Equity Compensation
 
The purpose of the Group’s long-term equity incentive compensation program has been to align executive compensation with stockholder interests, to create incentives for executive recruiting and retention, to encourage long-term performance by the Group’s executive officers, and to promote stock ownership. As with base salaries, the Committee reviews the competitive range of long-term equity compensation and total direct compensation (long-term equity compensation plus base salary) for similar positions within the competitive data in making decisions regarding long-term equity compensation awards for 2009. However, the Committee also believes that, in the interest of fostering the Group’s “one-team” approach, the annual equity incentive awards granted to each of the Group’s executive officers (other than the CEO) would be the same for each. The Committee recommended awarding the CEO a greater value of equity awards than the other executive officers because of his substantially greater level of responsibility and ability to influence the Group’s operational results. In addition, for both the CEO and the other executives, the grant values for 2009 were increased over the grant values for 2008 as a result of the Committee’s review of the competitive data and its desire to bring long-term equity incentive compensation values within the competitive range for similar positions within the competitive data, while maintaining the Group’s “one-team” approach for executives other than the CEO.
 
Each year the Committee first establishes the total value of the equity compensation awards to be granted to the CEO and the other executive officers. For 2009 these values were $300,000 and $75,000, respectively, vesting over four years. In 2009, we granted annual equity compensation awards to the executive officers in the form of stock-settled stock appreciation rights (SARs) and restricted stock awards (RSAs), with 50% of the total value of the annual equity compensation award allocated to each. The Committee believed this mix of SARs and RSAs creates an effective combination of incentives and retention for those executives who are most responsible for influencing stockholder value.
 
The Committee has granted equity awards to the executive officers in March of each year following the release of annual financial results. On March 3, 2009, the Committee granted to: (i) the CEO, RSAs covering 3,550 shares and SARs covering 22,000 shares; and (ii) each of the executive officers other than the CEO, RSAs covering 890 shares and SARs covering 5,500 shares. These share numbers were determined based upon the grant date fair value of the awards and the dollar value allocated to each executive officer.
 
Both the SARs and RSAs granted to the executive officers on March 3, 2009, pursuant to the California Water Service Group Equity Incentive Plan (the “Incentive Plan”) vest in monthly installments over 48 months following the date of grant. In addition, the SARs have a ten-year term. The exercise price of the SARs is the closing price for the Group’s common stock on the New York Stock Exchange on the grant date. Neither the SARs nor the RSAs provide for automatic vesting acceleration if there is a change in control or in the ownership of the Group.
 
In November of 2009, the Committee, after reviewing competitive data for each executive, approved the total value of the equity compensation awards to be granted to the CEO and the other executive officers for 2010. These values were $315,000 (CEO) and $75,000 (other executive officers), and were granted on March 2, 2010, in the form of RSAs. The Committee decided to change the form of the 2010 long-term equity incentive compensation from 50% RSAs and 50% SARs to 100% RSAs after observing that companies similar to the Group tend to

Table of Contents

experience steady growth in revenue and profit, but do not always see this value growth reflected in its stock price. As such, the Committee determined that SARs, whose value is primarily driven by market volatility, were not ideal for compensating executives who may be increasing the Group’s value but whose performance is not reflected in the Group’s stock price appreciation. In addition, the Committee observed that the Group records a significant accounting expense each year related to the grants of SARs to the executives, however, few executives have actually gained any economic benefits from those awards.
 
Basic and Supplemental Pension Plan Benefits
 
In addition to the tax-qualified defined benefit plan that covers virtually all union and non-union employees, the Group provides supplemental retirement benefits to executive officers under the Supplemental Executive Retirement Plan (SERP). The plan is an unfunded, unsecured obligation of the Group and is designed to assist in attracting and retaining key executives while providing a competitive, total compensation program. In addition, since we do not provide a significant amount of total compensation in the form of equity incentives, SERP benefits provide executive officers with retirement security. Furthermore, the plan is designed, in part, to make up for limitations imposed by the Internal Revenue Code on allocations and benefits that may be paid to our executive officers under the Group’s tax-qualified plan. Since the tax code restricts benefits under our tax-qualified plan, our executives otherwise would not be eligible to receive the retirement benefits that are proportional to the benefits received by our employees that generally are based on compensation.
 
Deferred Compensation Plan
 
The Group maintains a deferred compensation plan for its directors, officers, and qualified managers. The plan is intended to promote retention by providing eligible employees, including the executive officers, with a long-term savings opportunity on an income tax-deferred basis.
 
401(k) Plan
 
All employees satisfying the eligibility requirements are entitled to participate in our 401(k) plan and receive matching contributions from the Group. Pursuant to the plan, executive officers are entitled to contribute up to the statutory limit set by the Internal Revenue Service and effective January 1, 2010, the Group matches 75 percent for each dollar contributed up to a maximum company match of 6%.
 
Limited Perquisites
 
As part of the Group’s automobile policy, the Group’s executive officers have the use of a company-owned automobile. The Committee believes that the provision of a company-owned automobile allows our executive officers to work more efficiently because many of the geographic areas served by the Group are most effectively reached by automobile as opposed to other forms of mass transportation, such as airlines. Any personal mileage incurred by the executive is taxed as additional compensation in accordance with IRS regulations. Other than this automobile benefit, the Committee’s general philosophy is not to provide perquisites and other personal benefits of substantial value to the Group’s executive officers.
 
Severance Arrangements
 
None of the executive officers is a party to an individual employment agreement with the Group that provides for severance benefits. In addition, we do not provide executive officers with single-triggered change in control benefits.
 
Consistent with the Group’s compensation philosophy, the Committee believes that the interests of stockholders are best served if the interests of senior management are aligned with those of the Group’s stockholders. To this end, the Group provides change in control severance benefits to executive officers under the Group’s Executive Severance Plan to reduce any reluctance of the executive officers to pursue or support potential change in control transactions that would be beneficial to the Group’s stockholders. We adopted the plan in 1998, and its purpose is to promote the continued employment and dedication of our executives without distraction in the face of a potential change in control transaction. The Executive Severance Plan provides severance pay equal to three times base salary

to each of the executive officers if their employment is terminated without good cause or they resign for good reason during the two-year period following a change in control.
 
In addition to the Executive Severance Plan, each executive officer is covered by the Group’s general severance policy stating that each non-union employee of Group whose employment is terminated without cause is entitled to severance pay of either one week’s pay after completing two years of service or two weeks’ pay after completing five or more years of service, provided at least two weeks’ notice is given. Under the Group’s policies, all executive officers are entitled to a pay-out of six weeks of vacation time upon any termination of employment.
 
Determining Executive Compensation
 
Each year the Committee reviews, assesses, and recommends to the Board of Directors all compensation for executive officers after determining that the compensation for these individuals is competitive relative to companies of comparable size, complexity, location and business nature (see below for additional discussion of this comparison). In addition, the Committee approves the retention, fees, and termination of any compensation consultant or compensation consulting firm used to assist in the evaluation of director and executive compensation. With respect to 2009 compensation decisions, the Committee retained the services of an independent compensation consultant, PPA, for investigation into and advice on total compensation for executive officers. The Committee believes that having an independent evaluation of executive officer compensation is a valuable tool for the Committee, the Group and stockholders. PPA is not engaged to perform any additional work for the Group.
 
The Committee retained PPA for a number of purposes, including:
 
  •  Constructing and reviewing compensation comparisons from readily available published survey data; and
 
  •  Performing a competitive assessment of the Group’s compensation programs, practices, and levels for its directors, executive officers and other senior officers.
 
The Committee made a number of compensation recommendations, including those pertaining to the executive officers, that were based on the competitive assessments provided by and through consultation with PPA. The Committee’s recommendations were made, however, entirely by the Committee, using its sole discretion.
 
Total compensation level for executives is based on one or more of the following factors:
 
  •  The individual’s duties and responsibilities within the Group;
 
  •  The individual’s experience and expertise;
 
  •  The compensation levels for the individual’s peers within the Group;
 
  •  Compensation levels for similar positions based on a review of published compensation surveys; and
 
  •  The levels of compensation necessary to recruit, retain, and motivate executives.
 
In order to determine competitive compensation practices for 2009, the Committee relied, in part, on published compensation data from the following sources:
 
  •  Saje Consulting Group — Investor-Owned Water Utility Compensation and Benefits Survey
 
  •  Watson Wyatt Data Services — Top Management Compensation Survey and Top Management Compensation Calculator
 
  •  Mercer Human Resources Consulting — Executive Compensation Survey
 
PPA utilized the data from these sources (the “competitive data”) to compile the competitive pay information comparing each officer’s compensation to the 25th, 50th, and the 75th percentiles for the executive officer’s position. The Committee is not provided the names of the companies in any of the surveys. With respect to compensation decisions for 2009, the Committee did not review proxy data for individual companies in making compensation decisions and instead focused on competitive data from established published surveys.
 
After consideration of the competitive data, the Committee makes decisions regarding each individual executive’s target total compensation opportunities based on Group and individual performance and the need


20


Table of Contents

to attract, motivate, and retain an experienced and effective management team. The Committee examined the relationship of each executive’s base salary, long-term equity incentives and total compensation (base salary plus long-term equity incentives) to the competitive data at the 25th, 50th, and 75th percentiles for the executive’s position within the competitive data.
 
In making compensation recommendations for the 2009 fiscal year for the executive officers, the Committee’s general objective was to set total compensation within a “competitive range” for each executive’s position based on the competitive data. The Committee considers the “competitive range” to mean that compensation levels are within plus or minus 20% of the median compensation levels as determined by reference to the competitive data. Actual compensation decisions for the executive officers were, however, influenced by a variety of additional factors, including considerations of each individual’s experience, expertise and performance, the Group’s performance, and internal equity among the executive officers.
 
Tax and Other Compensation Policies
 
When designing compensation policies and setting compensation levels, the Group considers the potential tax treatment of the compensation, but the primary factor influencing program design is the support of business objectives. The Committee has reviewed the Group’s compensation structure in light of Section 162(m) of the Internal Revenue Code (“Section 162(m)”), which limits the amount of compensation that the Group may deduct for federal income tax purposes for any year to $1,000,000 for our CEO and each of our three highest compensated officers other than the CEO and CFO. There are certain exceptions to this limit, one of which is for “performance-based compensation,” as defined under Section 162(m). SARs granted by the Group are intended to satisfy the requirements for the “performance-based compensation,” exception, and therefore do not count against the $1,000,000 deductibility limit. RSAs granted by the Group do not qualify as “performance-based compensation,” and thus do count against the $1,000,000 deductibility limit. In 2009, no executive officer’s compensation exceeded the limitation set by Section 162(m), meaning all compensation paid to the executive officers was tax-deductible.
 
Historically, the Committee has not used equity awards as a significant portion of executive compensation. Thus, the Group currently does not have any formal stock ownership guidelines for its executive officers, nor does it require that executive officers own a specific number of shares.

(1) The executive officers were not entitled to receive payments which would be characterized as “bonus” or “non-equity incentive plan compensation” payments for the fiscal year ended December 31, 2009, 2008 and 2007.
 
(2) Amounts reflect the full grant date fair value of RSAs (“Stock Awards” column) and SARs (“Option Grants” column) granted in the years shown, calculated in accordance with FASB Accounting Standards Codification (“ASC”) Topic 718, disregarding estimates for forfeitures. Assumptions used in the calculation of these amounts are included in footnote 13 of Group’s annual report on Form 10-K filed with the Securities and Exchange Commission on March 1, 2010.
 
(3) Amounts in this column reflect the actuarial increase in the present value of the executive officer’s benefits under the Group’s pension plan and Supplemental Executive Retirement Plan (SERP) determined using interest rate and mortality rate assumptions consistent with those used in the Group’s financial statements and includes amounts which the executive officers may not currently be entitled to receive because such amounts are not vested. Earnings on the nonqualified deferred compensation plan are noted on the Nonqualified Deferred Compensation table for those officers participating in the plan. Earnings have been excluded from this table since earnings were not at above market or at preferential rates.
 
(4) All other compensation is comprised of 401(k) matching contributions made by Group on behalf of the executive officer, the personal use of company-provided cars, and any miscellaneous reimbursed expenses that may be taxable. The value attributable to personal use of company-provided cars is included as compensation on the W-2 of each executive officer who receives such benefits. Each such officer is responsible for paying income tax on such amount.

(1) Both the SARs and RSAs granted to the executive officers on March 3, 2009 pursuant to the Incentive Plan vest in monthly installments over 48 months following the date of grant. In addition, the SARs have a ten-year term. The exercise price of the SARs is the closing price for the Group’s common stock on the New York Stock Exchange on the grant date. Neither the SARs nor the RSAs provide for automatic vesting acceleration if there is a change in control or in the ownership of the Group.

The benefits under the Supplemental Executive Retirement Plan (the “SERP”) are obtained by applying the benefit provisions of the California Water Service Pension Plan (the “Pension Plan”), a tax-qualified plan, to all compensation included under the Pension Plan, without regard to these limits, reduced by benefits actually accrued under the Pension Plan. Under the SERP, all eligible officers are fully vested after 15 years of service and at age 60. SERP participants are eligible for early retirement starting at age 55 and would receive a reduced benefit ranging from 74% to 95% of their monthly SERP benefit upon early retirement between the ages of 55 and 60. Under the Pension Plan, all eligible employees, including officers, are fully vested after 35 years of service.
 
The combined maximum benefit payout under the SERP and Pension Plan achievable by an officer is 60% of the average, eligible compensation (including salary, bonus and car allowance) paid over the previous 36 months prior to retirement.

The Deferred Compensation Plan provides specified benefits to select group of management and highly compensated employees who contribute materially to the continued growth, development and future business success of California Water Service Group. The Deferred Compensation Plan permits the Group’s executives and eligible managers to defer up to 50% of their base salary. The Group does not make any contributions to the deferred compensation plan. The Deferred Compensation Plan’s investment options are similar, but not identical, to the Group’s tax-qualified 401(k) plan and are funded by a Rabbi trust created for the funding of such benefits. Benefits under the Deferred Compensation Plan are payable by the Group upon separation from service with the Group either in lump sum at separation, in monthly installments over five years following separation or in lump sum or installments commencing five years following separation.
 
Potential Payments Upon Termination or Change in Control
 
The information below describes certain compensation that would have become payable under existing plans and contractual arrangements assuming a termination of employment, or a change in control and termination of employment had occurred on December 31, 2009, given the executive officers’ compensation and service levels as of such date. In addition to the benefits described below, upon any termination of employment, each of the executive officers would also be entitled to the benefits described in the table of Pension Benefits for Fiscal Year 2009 above and the amount shown in the column labeled “Aggregate Balance at Last FY” of the table of Nonqualified Deferred Compensation for Fiscal Year 2009 above.
 
On December 16, 1998, the Group adopted the Executive Severance Plan. The Executive Severance Plan provides that if within 24 months following a change in control of the Group, the executive officer’s employment is


26


Table of Contents

terminated for any reason other than good cause or by the executive for good reason, the Group will make a cash payment to the executive officer an amount equal to three times such executive officer’s base salary on the date of the change in control or on the date that the officer’s employment terminates, whichever is greater. The payments would be paid in three equal annual installments commencing on the first of the month following the month in which the officer’s employment terminated and payable thereafter on the anniversary of the initial payment date.
 
Each officer’s entitlement to the severance payment is conditioned upon execution of a release agreement. Additionally, the executive officer forfeits the right to receive the severance payment if he or she violates the non-solicitation and confidentiality provisions of the Executive Severance Plan.
 
For purposes of the Executive Severance Plan, the term “change in control” means the occurrence of (i) any merger or consolidation of the Group in which the Group is not the surviving organization, a majority of the capital stock of which is not owned by the shareholders of the Group immediately prior to such merger or consolidation; (ii) a transfer of all or substantially all of the assets of the Group; (iii) any other corporate reorganization in which there is a change in ownership of the outstanding shares of the Group wherein thirty percent (30%) or more of the outstanding shares of the Group are transferred to any person; (iv) the acquisition by or transfer to a person (including all affiliates or associates of such person) of beneficial ownership of capital stock of the Group if after such acquisition or transfer such person (and their affiliates or associates ) is entitled to exercise thirty percent (30%) or more of the outstanding voting power of all capital stock of the Group entitled to vote in elections of directors; or (v) the election to the Board of Directors of the Group of candidates who were not recommended for election by the Board of Directors of the Group in office immediately prior to the election, if such candidates constitute a majority of those elected in that particular election.
 
For purposes of the Executive Severance Plan, “good cause” will be deemed to exist if (i) the applicable officer engages in acts or omissions that result in substantial harm to the business or property of the Group and that constitute dishonesty, intentional breach of fiduciary obligation or intentional wrongdoing; or (ii) the applicable officer is convicted of a criminal violation involving fraud or dishonesty.
 
For purposes of the Executive Severance Plan, “good reason” will be deemed to exist if, without the applicable officer’s consent, (i) there is a significant change in the nature or the scope of the applicable officer’s authority or in his or her overall working environment; (ii) the applicable officer is assigned duties materially inconsistent with his or her present duties, responsibilities and status; (iii) there is a reduction in the applicable officer’s rate of base salary or bonus; or (iv) the Group changes by 100 miles or more the principal location in which the applicable officer is required to perform services.
 
Had a change in control occurred during fiscal 2009 and had their employment been terminated on December 31, 2009, either without good cause or by the executive for good reason, the executive officers would have been eligible to receive the payments set forth below.
 
In addition to the Executive Severance Plan, each executive officer is covered by the Group’s general severance policy. Under the severance policy, each non-union employee of Group whose employment is terminated without cause is entitled to severance pay of either one week’s pay after completing two years of service or two weeks’ pay after completing five or more years of service, provided at least two weeks’ notice is given. In addition, all executive officers are entitled to a payout of six weeks of vacation time upon any termination of employment, which may be paid either in lump sum at termination or in installments over six weeks. In the absence of a change in control, had their employment been terminated on December 31, 2009, without cause, the executive officers would have been eligible to receive the payments set forth below.

In addition to the benefits described above, if an executive officer’s employment terminates within one year of a change of control, his or her options continue to vest on the original vesting schedule. Please refer to the table of Outstanding Equity Awards at Fiscal Year-Ended 2009 above for more information regarding these awards.
 
Director Compensation
 
For Fiscal Year Ended 2009
 
The Group’s nonemployee directors receive cash retainers and meeting fees and equity awards for their service.
 
Nonemployee directors receive a $26,500 annual Board retainer, except for the Audit Committee chair who receives $35,500 and the Chairman of the Board who receives $80,000. In addition, each Board member receives $2,200 for each Board meeting attended, and $1,800 for each committee meeting attended. Further, each committee chair receives an additional fee of $1,800 for each committee meeting chaired.
 
Each nonemployee director also receives annual restricted stock grants under the Group’s equity compensation plan. The amount of these awards is determined each year by the Board. These awards are generally granted at the same time as awards are made to the Group’s executive officers and fully vest one year from the grant date. For 2009, each nonemployee director received shares of restricted stock valued at $45,288.
 
In November of 2009, after performing its annual compensation review, the Committee approved increases to the foregoing amounts, effective January 1, 2010, as follows: nonemployee directors will receive a $27,500 annual Board retainer, except for the Chairman of the Board who receives $80,000. The Audit Committee chair receives an additional $9,000 retainer, and the Finance and Risk Management Committee chair receives an additional $2,500 retainer. The chairs of the Nominating/Corporate Governance Committee and Organization and Compensation Committee receive an additional $4,000 retainer, respectively. In addition, each Board member receives $2,300 for each Board meeting attended, and $1,800 for each committee meeting attended. Further, each committee chair will receive an additional fee of $1,800 for each committee meeting chaired.
 
In November of 2009, after performing its annual compensation review the Committee approved grants of restricted stock to each Board member for the 2010 fiscal year valued at $48,670. The grants were made in March of 2010.
 
The Board of Directors strongly encourages stock ownership by directors. Pursuant to the Group’s Corporate Governance Guidelines, available on the Group’s website at http://www.calwatergroup.com, beneficial ownership of an aggregate amount of shares having a value of four times the amount of the annual director retainer is desirable. Directors elected before April 27, 2005, who owned less than the desirable amount were strongly encouraged to increase their holdings to that amount by April 26, 2009. Directors elected on or after April 27, 2005, who own less than the desired amount are strongly encouraged to increase their holdings to four times the annual director retainer level before the end of four years from the date of their election to the Board.
 
Directors may elect to defer cash compensation payable to them under the Group’s deferred compensation plan in the same manner as applicable to the Group’s executive officers as described above.

Table of Contents

In addition, the Group maintains a Director Retirement Plan for the benefit of its nonemployee directors. In December 2005, this plan was closed to new participants, however, each of the nonemployee directors listed in the table below (except for Mr. Guiles) were, at that time, participants in the plan and thus continue to accrue benefits thereunder. Under the Director Retirement Plan, a director who participates in the plan and retires after serving on the Board for a total of five or more years will receive a retirement benefit equivalent to $22,000 per year. This benefit will be paid for the number of years the director served on the Board, up to 10 years. No amounts were paid to directors under this program in fiscal 2009.

Based on our review of and the discussions with management with respect to the Compensation Discussion and Analysis, our Organization and Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement and in the Group’s Annual Report on Form 10-K for the fiscal year ended December 31, 2009, for filing with the SEC.

ORGANIZATION AND COMPENSATION COMMITTEE INTERLOCKS AND INSIDER
PARTICIPATION
 
No member of the Organization and Compensation Committee was an officer or employee of the Group or any of its subsidiaries during 2009, nor was any such member previously an officer of the Group or any of its subsidiaries. No member of the Organization and Compensation Committee had any material interest in a transaction of the Group or a business relationship with, or any indebtedness to the Group, in each case that would require disclosure under “Certain Related Persons Transactions” included elsewhere in this Proxy Statement.
 
None of the executive officers or nonexecutive officers of the Group have served on the Board of Directors or on the Organization and Compensation Committee of any other entity, any of whose officers served either on the Board of Directors or on the Organization and Compensation Committee of the Group.
 
CERTAIN RELATED PERSONS TRANSACTIONS
 
Our wholly-owned subsidiary, CWS Utility Services (CWSUS), provided laboratory services to a subsidiary of San Jose Water Corporation (SJWC), which has ownership of over 5.29% of our common stock outstanding. The contract was cancelled in 2010 by the SJWC subsidiary. The rates charged were comparable to rates charged to other third parties. We received approximately $107,000 from SJW for water sampling. The revenue and income from this activity is not significant to our business. Certain of our properties are in SJWC’s service territory. As a result, we paid SJWC approximately $85,000 for utility water service.
 
Procedures for Approval of Related Persons Transactions
 
The Group does not have a stated policy for considering related-party transactions. Instead, the Board of Directors reviews all related-persons transactions, for officers and directors on a case by case basis and approves all such transactions in accordance with the Delaware general corporation law.

REPORT OF THE AUDIT COMMITTEE
 
The Audit Committee oversees the Group’s financial reporting process on behalf of the Board of Directors. The Committee’s purpose and responsibilities are set forth in the Audit Committee Charter. The current charter is available on the Group’s website at http://www.calwatergroup.com. The Committee consists of five members, each of whom meets the New York Stock Exchange standards for independence and the Sarbanes-Oxley Act independence standards for audit committee membership, and has at least one member meeting the requirements of an audit committee financial expert. During 2009, the Committee met five times.
 
The Group’s management has primary responsibility for preparing the Group’s financial statements and the overall reporting process, including the Group’s system of internal controls. Deloitte & Touche LLP, the Group’s independent registered public accounting firm, audited the financial statements prepared by the Group and expressed their opinion that the financial statements fairly present the Group’s financial position, results of operations and cash flows in conformity with generally accepted accounting principles. Deloitte & Touche LLP also audited that the Group maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009.
 
In connection with the December 31, 2009, financial statements, the Audit Committee:
 
(1) reviewed and discussed the audited financial statements with management and the independent registered public accounting firm;
 
(2) discussed with the independent registered public accounting firm the matters required by Statement on Auditing Standards No. 114, “The auditor’s communication with those charged with governance,” as amended;
 
(3) received from Deloitte & Touche LLP and discussed with the auditor written disclosures required by the “Public Company Accounting Oversight Board,” also discussed with Deloitte & Touche LLP the firm’s independence, and considered whether the firm’s provision of non-audit services and the fees and costs billed for those services are compatible with Deloitte & Touche LLP’s independence; and
 
(4) met privately with the Group’s independent registered public accounting firm and internal auditors, each of whom has unrestricted access to the Audit Committee, without management present, and discussed their evaluations of the Group’s internal controls and overall quality of the Group’s financial reporting and accounting principles used in preparation of financial statements. The Committee also met privately with the Group’s Chairman and the President and CEO, the Chief Financial Officer and the Controller to discuss the same issues.
 
Based upon these reviews and discussions, the Audit Committee recommended to the Board that the audited financial statements be included in the Annual Report on Form 10-K to be filed with the Securities and Exchange Commission.

OTHER MATTERS
 
Adjournment
 
Notice of adjournment need not be given if the date, time and place thereof are announced at the Annual Meeting at which the adjournment is taken. However, if the adjournment is for more than 30 days, or if a new record date is fixed for the adjourned Annual Meeting, a notice of the adjourned Annual Meeting will be given to each stockholder entitled to vote at the Annual Meeting. At adjourned Annual Meetings, any business may be transacted which might have been transacted at the original Annual Meeting.
 
Cost of Proxy Solicitation
 
The Group will bear the entire cost of preparing, assembling, printing and mailing this Proxy Statement, the proxies and any additional materials which may be furnished by the Board to stockholders. The solicitation of proxies will be made by the use of the U.S. postal service and also may be made by telephone, or personally, by directors, officers and regular employees of the Group, who will receive no extra compensation for such services. Morrow & Company, LLC, 470 West Avenue, Stamford, CT 06902 was hired to assist in the distribution of proxy materials and solicitation of votes for $8,500, plus out-of-pocket expenses. The Group will reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to stockholders.
 
Other Matters
 
The Board is not aware of any matters to come before the Annual Meeting other than the proposals for the election of directors and the ratification of the selection of the independent registered public accounting firm. If any other matters should be brought before the meeting or any adjournment thereof, upon which a vote properly may be taken, the proxy holders will vote in their discretion unless otherwise provided in the proxies. The report of the Organization and Compensation Committee, the report of the Audit Committee, and the statement of independence of Audit Committee members referred to under “Board Structure — Committees: Audit” are not to be considered as incorporated by reference into any other filings which the Group makes with the Securities and Exchange Commission under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended. These portions of this Proxy Statement are not a part of any of those filings unless otherwise stated in those filings.
 
Code of Ethics
 
The Group has adopted a written code of ethics that applies to its principal executive officer, principal financial officer and all other officers. The Group has also adopted codes of ethics for its employees and directors. The codes are posted on the Group’s website at http://www.calwatergroup.com. The codes are also available in written form upon request to Corporate Secretary, California Water Service Group, 1720 North First Street, San Jose, California 95112-4598.
 
Stockholders Sharing an Address
 
The SEC allows us to deliver a single proxy statement and annual report to an address shared by two or more of our stockholders. This delivery method, referred to as “householding,” can result in significant cost savings for us. In order to take advantage of this opportunity, banks and brokerage firms that hold shares for stockholders who are the beneficial owners, but not the record holders, of the Group’s shares, have delivered only one proxy statement and annual report to multiple stockholders who share an address unless one or more of the stockholders has provided contrary instructions. For stockholders who are the record holders of the Company’s shares, the Company may follow a similar process absent contrary instructions. The Group will deliver promptly, upon written or oral request, a separate copy of the proxy statement and annual report to a stockholder at a shared address to which a single copy of the documents was delivered. A stockholder who wishes to receive a separate copy of the proxy statement and annual report, now or in the future, may obtain one, without charge, by addressing a request to the Corporate Secretary, California Water Service Group, 1720 North First Street, San Jose, California 95112-4598 or calling (408) 367-8200. Stockholders of record sharing an address who are receiving multiple copies of proxy materials and


33


Table of Contents

annual reports and wish to receive a single copy of such materials in the future should submit their request by contacting us in the same manner. If you are the beneficial owner, but not the record holder, of the Group’s shares and wish to receive only one copy of the proxy statement and annual report in the future, you will need to contact your broker, bank or other nominee to request that only a single copy of each document be mailed to all stockholders at the shared address in the future.
 
Copies of Annual Report on Form 10-K
 
The Group, upon request, will furnish to record and beneficial holders of its common stock, free of charge, a copy of its Annual Report on Form 10-K (including financial statements and schedules but without exhibits) for fiscal year 2009. Copies of exhibits to Form 10-K also will be furnished upon request for a payment of a fee of $0.50 per page. All requests should be directed to Corporate Secretary, California Water Service Group, 1720 North First Street, San Jose, California 95112-4598.
 
Electronic copies of the Group’s 10-K, including exhibits, and this Proxy Statement will be available on the Group’s website at: http://www.calwatergroup.com.
