PART III
Item 11. Executive Compensation
COMPENSATION DISCUSSION AND ANALYSIS
Philosophy
     Our executive compensation program is designed to attract and retain qualified executive management critical to the Company’s growth and long-term success, and reward them for superior performance.
     We believe that the compensation of our Named Executive Officers (as defined below under the heading “Compensation of Executive Officers”) should reflect their success as individuals and as a management team in attaining key operating objectives, such as growth of revenues and growth of operating earnings, and ultimately, in attaining an increased value for our stock. We believe that

Table of Contents

the performance of our Named Executive Officers in managing our company, considered in light of general economic and specific company, industry and competitive conditions, should be the basis for determining their total compensation. In allocating total compensation between cash compensation and equity compensation, we focus on creating incentives geared to both short term and long term performance, with the primary goal being to increase shareholder value over the long term. We seek to align our Named Executive Officers’ compensation with the interest of the Company’s shareholders to create value over the long-term through our stock option program. In setting our Named Executive Officers’ cash and equity compensation, we intend to be competitive with other similarly situated companies in our industry.
     As part of its annual review of executive compensation, our Compensation Committee takes into account each Named Executive Officer’s total compensation package from prior years, as well as information contained in a market survey commissioned by the Company. The market survey analyzes compensation for directors and executive officers at SINA’s peer companies who are determined by reference to market cap and industry. Typically, our CEO makes compensation recommendations to the Compensation Committee with respect to the executive officers who report to him. Such executive officers are not present at the time of these deliberations. In general, the chairman of the Compensation Committee makes compensation recommendations to the Compensation Committee with respect to our CEO, who is absent from that meeting. The Compensation Committee may accept or adjust such recommendations and also makes the sole determination for executive compensation.
Overview of Compensation and Process
     Elements of compensation for our Named Executive Officers include: base salary, incentive cash bonuses, stock option awards, and housing allowance.
     Base Salary. The level of base salary is established primarily on the basis of the individual’s qualifications and relevant experience, the strategic goals for which he or she has responsibility, and the compensation levels at companies which compete with the Company for business and executive talent. In January 2006, we review salaries annually and may adjust them from time to time if needed to reflect individual performance, changes in position or responsibility of the executives or changes in the market conditions and peer company compensation levels. We commissioned a market survey of compensation for directors and executive officers at SINA’s peer companies who are determined by market cap and industry. The market cap peer group consisted of 12 companies with median market capitalization of $1,250,000,000 median sales of $260,000,000 and median net income of $31,500,000, which was roughly equivalent to SINA’s market capitalization, sales and net income. The industry peer group consisted of 10 companies with median market capitalization of $690,000,000, median sales of $67,000,000 and median net income of $$21,000,000. Since SINA’s market capitalization, median sales and net income was roughly equivalent to the 75th percentile of the industry peer group, 75th percentile figures were used for this analysis. The market survey concluded that the compensation level at SINA at the time was below market when compared to the market cap peer group and industry peer group except for long-term incentive compensation for our CEO (and as a result, overall compensation of our CEO), which was above market, and overall compensation for our Chief Operating Officer, which was at market. On June 7, 2006, the Compensation Committee approved an increase to the annual base salaries, effective from June 2006, for Charles Chao, our CEO and President, from $260,000 to RMB2,400,000 (equivalent to $301,102.79 assuming an exchange rate of RMB7.9707 for $1), and Herman Yu, our Acting CFO, from $143,253 to RMB1,320,000 (equivalent to $165,606.53 assuming an exchange rate of RMB7.9707 for $1). Company performance does not play a significant role in the determination of base salary. The base salaries paid to our Named Executive Officers for 2006 are shown in the Summary Compensation Table.
     Incentive Cash Bonuses. Our Named Executive Officers are eligible to receive cash bonuses which are paid on the basis of their success in achieving designated individual goals and the Company’s success in achieving specific company-wide goals. Specifically, our Named Executive Officers were eligible to earn a cash bonus based on 2006 Company performance pursuant to the 2006 Management Bonus Plan (the “2006 Bonus Plan”). Under the 2006 Bonus Plan, a total bonus pool of up to 4% of 2006 pro-forma net income before taxes was established upon the satisfaction of certain performance goals as follows:

     Under the 2006 Bonus Plan, Charles Chao, our CEO and President, was eligible to receive up to 30% of the total bonus pool, and Herman Yu, our Acting CFO, was eligible to receive up to 6% of the total bonus pool. The total actual payout under the 2006 Bonus Plan was RMB17.9 million. In February 2007, the Compensation Committee gave the final approval for Mr. Chao to receive RMB4,087,040 and Mr. Yu to receive RMB1,077,408 under the 2006 Bonus Plan. The actual payouts under the 2006 Bonus Plan to our Named Executive Officers are shown in the Summary Compensation Table. The Compensation Committee has established the 2007 Management Bonus Plan (the “2007 Bonus Plan”) that contemplates a total cash bonus pool of up to 4% of 2007 pro-forma net income before taxes based on substantially the same performance goal metrics as the 2006 Bonus Plan:
     Cash bonuses may also be awarded to our Named Executive Officers on a discretionary basis at any time, none of which was rewarded in 2006. While the Compensation Committee has granted discretionary bonuses in the past, it is unlikely to do so going forward due to the adoption of the 2007 Bonus Plan and the expectation that it will continue to adopt similar annual performance bonus plans in the future.
     Stock Option Awards. We grant stock options under our stock option plans to our Named Executive Officers to provide them with an incentive to maximize long-term shareholder values. We believe that stock options that give the recipient a significant equity stake in the Company closely aligns his or her interests with those of the Company’s shareholders. Factors considered in granting stock options to Named Executive Officers, including determining the appropriate size of such grants, include the individual’s position in the Company, his or her performance and responsibilities, and comparability considerations with SINA’s market cap peer group and industry peer group. In 2006, comparability was based on the market survey completed in January of 2006, which concluded that the long-term incentive value for our Named Executive Officers at the time was below market when compared to our market cap peer group and industry peer group, except for our CEO position, whose long-term incentive value was above market when compared to SINA’s industry peer group. Each stock option grant allows the Named Executive Officer to acquire Company ordinary shares at a per share price equal to the closing selling price per share of the Company’s ordinary shares on the Nasdaq National Market on the date of grant over a specified period of time (up to 10 years). The stock options typically vest in periodic installments over a four-year period, contingent upon the Named Executive Officer’s continuous service with the Company or certain affiliates of the Company, although very rarely exceptions may be made when deemed necessary or appropriate. There has been only one exception within the last three years, pursuant to which Charles Chao, our CEO and President, received his 2006 award with a three-year vesting schedule detailed below. Accordingly, a stock option will provide a realizable benefit to the Named Executive Officer only if he or she remains in the Company’s service, and then only if the market price of the Company’s ordinary shares appreciates over the stock option term.
     We have not adopted any specific policy regarding the amount of stock option grants to be awarded to our Named Executive Officers or the timing of such stock option grants. Stock option grants awarded to our Named Executive Officers and other key employees are typically granted annually in conjunction with the review of the individual performance of each of our employees and a review of a market survey commissioned by the Company.
     On June 7, 2006, the Compensation Committee granted stock options to each of the following Named Executive Officers: Charles Chao, our CEO and President, 390,000 shares, Herman Yu, our Acting CFO, 75,000 shares, and Benjamin Tsiang, our Executive Vice President, 60,000 shares, pursuant to the Company’s 1999 Stock Plan, at an exercise price of $24.73 per share, which represents the closing selling
price per share of the Company’s ordinary shares on the Nasdaq National Market on June 7, 2006. These options have a term of 6 years, but are subject to earlier termination in connection with termination of continuous service with the Company or certain affiliates of the Company. The stock option granted to Mr. Chao vests over a three-year term with 1/6th of the shares covered by the option vesting on the 6-month anniversary of the date of the grant and the remaining shares vesting ratably on a monthly basis over the remaining term of the option. The stock option granted to each of Mr. Yu and Mr. Tsiang vests over a four-year term with 12.5% of the shares covered by the option vesting on the 6-month anniversary of the date of the grant and the remaining shares vesting ratably on a monthly basis over the remaining term of the option.

We also do not maintain any executive retirement programs, such as executive pension plans, deferred compensation plans, or other executive retirement benefits.
     Change of Control and Severance Agreements. Certain of our Named Executive Officers receives cash payments and other benefits upon the occurrence of termination of employment or a change of control of the Company when certain conditions are satisfied. These arrangements are reported below under the heading “Potential Payments upon Termination or Change of Control.”

Potential Payments upon Termination or Change of Control
Terms of Potential Payments — Termination
Charles Chao
     In the event that Mr. Chao’s employment is terminated without cause or if a constructive termination occurs (either event, an “Involuntary Termination”), Mr. Chao shall be entitled to receive payment of severance benefits equal to his regular monthly salary for (i) 18 months if the remaining term of the Employment Agreement (the “Remaining Term”) is more than or equal to 18 months, (ii) the Remaining Term if the Remaining Term is less than 18 months but more than 12 months, or (iii) 12 months if the Remaining Term is equal to or less than 12 months (the “Severance Period”), provided that Mr. Chao executes a release agreement at the time of such termination. An amount equal to 6 months of such severance benefits shall be paid on the 6-month anniversary of the termination date, and the remaining severance benefits shall be paid ratably over the remaining Severance Period in accordance with the Company’s standard payroll schedule. Additionally, upon an Involuntary Termination, Mr. Chao will be entitled to receive any bonus earned as of the date of such termination, which amount shall be paid on the 6-month anniversary of Mr. Chao’s termination date. The Company will also reimburse Mr. Chao over the Severance Period for health insurance benefits with the same coverage provided to Mr. Chao prior to his termination, provided that reimbursement for the first 6 months of the Severance Period shall be paid on the 6-month anniversary of Mr. Chao’s termination date and reimbursement for any remaining health insurance benefits shall be paid on the first day of each month during which Mr. Chao receives such health insurance benefits. Any unvested stock options or shares of restricted stock held by Mr. Chao as of the date of his Involuntary Termination will vest as to that number of shares that Mr. Chao would have vested during the Severance Period if he had continued employment with the Company through such period, and Mr. Chao shall be entitled to exercise any such stock options through the date that is the later of (x) the 15th day of the third month following the date the stock options would otherwise expire, or (y) the end of the calendar year in which the stock options would otherwise expire. Mr. Chao is not eligible for any severance benefits if his employment is terminated voluntarily or if he is terminated for cause.
     In the event that Mr. Chao voluntarily elects to terminate his employment, Mr. Chao will receive payment(s) for all salary and unpaid vacation accrued as of the date of his termination of employment and his benefits will be continued in accordance with our then-existing benefits plans and policies in effect on the date of termination and in accordance with applicable law. In the event that Mr. Chao’s employment is terminated for cause, then he shall not be entitled to receive payment of any severance benefits, but he will receive payment(s) for all salary and unpaid vacation accrued as of the date of such termination and his benefits will be continued in accordance with our then-existing benefits plans and policies in effect on the date of termination and in accordance with applicable law.

     In the event that Mr. Chao’s employment with the Company terminates as a result of his death or disability, Mr. Chao’s estate or representative will receive the amount of Mr. Chao’s target bonus for the fiscal year in which the death or disability occurs to the extent that the bonus has been earned as of the date of such death or disability, as determined by the Board of Directors or the Compensation Committee based on the specific corporate and individual performance targets established for such fiscal year. In addition, the change of control agreement between the Company and Mr. Chao, as further described below under “Terms of Potential Payments – Change of Control,” provides that if the termination is by reason of death or disability, Mr. Chao will be entitled to continued payment of his full base salary at the rate then in effect on the date of termination for a period of one year from the date of termination.
     During the term of the Employment Agreement and the Severance Period, if any, Mr. Chao has agreed to certain covenants relating to non-competition and non-solicitation of business. Additionally, during the term of the Employment Agreement and for 12 months thereafter, Mr. Chao has agreed to the non-solicitation of any employees of the Company.
     Under the terms of the Employment Agreement described above, if Mr. Chao had terminated his employment on December 31, 2006, under circumstances where such termination is an Involuntary Termination, it is estimated that he would have received payments of severance benefits in the amount of RMB3,600,000, which is equal to his regular monthly salary for 18 months. Mr. Chao would additionally receive an incentive bonus at approximately RMB4,087,040 if so determined by the Board of Directors or the Compensation Committee pursuant to the Company’s 2006 Management Bonus Plan. Mr. Chao would also be reimbursed for health insurance benefits valued at approximately $14,665. Apart from the above, Mr. Chao would additionally receive benefits valued at approximately $2,841,960, which reflects the expense that would have been recognized for financial statement reporting purposes in accordance with SFAS 123R without regard to estimated forfeitures from the continuous vesting of stock options as to the number of shares that would have vested during 18 months following December 31, 2006 (see note 13 of our 2006 Annual Report on Form 10-K filed on March 1, 2007 for or a more detailed discussion on the valuation model and assumptions used to calculate the fair value of our options).
     If Mr. Chao had terminated his employment on December 31, 2006, under circumstances where such termination is voluntary, for cause or by reason of death or disability, he would have received all salary and unpaid vacation accrued in the amount of $14,615. Mr. Chao would additionally receive the target bonus at approximately RMB4,087,040 and an annual base salary of RMB2,400,000 in the event that his employment had been terminated by reason of death or disability.
Terms of Potential Payments — Change of Control
     On February 1, 2001, the Company entered into a change of control agreement with Charles Chao. Under this change of control agreement, in general, a change of control shall be deemed to occur if (i) any person or entity acquires more than fifty percent or more of the combined voting power of the Company’s outstanding securities, (ii) during any period of two consecutive years there is an unwelcome change in a majority of the members of our board of directors, (iii) we merge or consolidate with another organization (other than a merger where our shareholders continue to own more than fifty percent of the combined voting power and with the power to elect at least a majority of the board of directors), (iv) our shareholders approve a complete liquidation or an agreement for the sale or disposition of all or substantially all of the Company’s assets, (v) there occurs any other event of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A promulgated under the Exchange Act.
     The change of control agreement provides for certain severance benefits in the event of a change of control as well as in the event of an involuntary termination after a change of control. Upon a change of control in which the successor corporation does not assume outstanding options, all such options shall become fully vested and exercisable. In addition, if Mr. Chao’s employment with the Company terminates without cause or if he resigns for good reason (as such terms are defined in the change of control agreements) within 24 months following a change of control, Mr. Chao will receive a pro-rata amount of the full value of any targeted annual bonus for the year in which he terminates, 100% of his annual base salary and 100% of his targeted annual bonus for the year in which he terminates, reimbursement in full of the applicable insurance premiums for him and his eligible dependents for first eighteen months that he and his dependents are eligible for health insurance coverage if a continuance of health insurance benefits are elected, continued D&O insurance coverage for six years after his termination, and an acceleration of all stock awards that are unvested as of his termination date. The change of control agreement also provide for a payment of an amount equal to the full value of the excise tax imposed by Section 4999 of the Internal Revenue Code should the Executive be subject to the excise tax on golden parachute payments under the Internal Revenue Code.

DIRECTOR COMPENSATION
     Our Amended and Restated Articles of Association provide that our directors may be compensated at the discretion of the Board of Directors. Our non-employee directors are eligible to participate in our 1999 Directors’ Stock Option Plan (the “1999 Directors’ Plan”). The 1999 Directors’ Plan provides for the grant to non-employee directors of (1) a nonstatutory share option to purchase 37,500 ordinary shares on the date on which a non-employee becomes a member of our Board of Directors, and (2) an additional nonstatutory share option to purchase 15,000 shares on the date of the annual general meeting for each Board member who has served on the Board of Directors for at least six months prior to such date. The 1999 Directors’ Plan was amended, effective as of June 23, 2006, to provide for, in lieu of the grants described above, the grant to non-employee directors of (1) a nonstatutory share option to purchase 30,000 ordinary shares on the date on which a non-employee becomes a member of our Board of Directors, and (2) an additional nonstatutory share option to purchase 12,000 shares on the date of the annual general meeting for each Board member who has served on the Board of Directors for at least six months prior to such date. In addition, effective as of June 23, 2006, each non-employee director shall receive an annual cash retainer of $20,000, the Chair of the Audit Committee shall receive an additional annual cash retainer of $5,000 and the Chair of the Compensation Committee shall receive an additional annual cash retainer of $3,000.
