2. Mercer Human Resource Consulting 2 Background ERCOT and the Public Utilities Commission of Texas (PUCT) asked Mercer to conduct a review of a benchmark sample of jobs to determine the competitive market position of ERCOT’s: – Base pay (annualized hourly wage or salary) – Total cash compensation (base pay plus cash bonus awards) Based on the results of the competitive review, Mercer was also asked to recommend changes to ERCOT’s pay program(s), where appropriate

3. Mercer Human Resource Consulting 3 Process and Methodology To complete the study, Mercer performed the following: Met with ERCOT and PUCT representatives to develop an understanding of ERCOT’s business operations, compensation philosophy and the jobs included in the study Assessed value of ERCOT’s benefits relative to other Texas employers Reviewed ERCOT job documentation to understand job content Obtained data from 22 published survey sources, the Texas State Auditor’s Office, Austin Energy, LCRA, and CPS Adjusted data, as appropriate, to reflect differences in job scope, responsibilities, reporting levels, skill requirements, and a 9/15/05 effective date Researched geographic differential practices for Austin, Texas

4. Mercer Human Resource Consulting 4 Process and Methodology (continued) Additional project steps included: Developed 25th, 50th, and 75th percentile market composite statistics for base pay and total cash compensation for 135 ERCOT benchmark jobs, representing 336 employees or 66% of ERCOT’s workforce Assessed ERCOT’s base pay and total cash compensation relative to the market 50th percentile (median) Combined benefits and compensation competitive assessment findings to develop relative market position for ERCOT’s total remuneration Met with ERCOT and PUCT to review draft findings and discuss warranted revisions and additional reviews Prepared final summary of findings and recommendations

5. Mercer Human Resource Consulting 5 Base Pay Analysis Our assessment of ERCOT’s base pay for the benchmark sample relative to aggregate market practices indicated the following: On average, base pay is approximately 2% above the median of the market In general, base pay tends to exceed the market median for lower level positions and fall below the market median for higher level positions Individual pay levels are widely dispersed – market variances range from 28% below to 49% above the market median, indicating salaries are not administered according to a consistent, market-aligned standard Salary ranges for many jobs are not aligned with market practices 32% of the benchmark employees fall outside a typical market competitive range (+/-15%)

7. Mercer Human Resource Consulting 7 Total Cash Compensation Analysis Our assessment of ERCOT’s target total cash compensation (TCC) for the benchmark sample relative to aggregate market practices indicated the following: On average, TCC (actual base pay plus target bonus award, where eligible) is approximately 1% below the median of the market Bonus eligible employees average target TCC that is 1% above the market median Target TCC is generally less competitive for higher level roles than for lower level roles As with base pay, individual target total cash compensation competitiveness varies widely The absence of bonus awards to lower level employees creates a short- fall when compared to market bonus practices; however, above market base salaries have helped ERCOT remain competitive with regard to TCC

8. Mercer Human Resource Consulting 8 Total Cash Compensation Analysis (continued) The use of variable pay is at all organizational levels is becoming common among employers in all industries:

10. Mercer Human Resource Consulting 10 Recommendations To the extent ERCOT desires to keep base pay and target total cash compensation in line with the median of the market, Mercer recommends the following: Add additional pay ranges to the existing ERCOT structure to ensure market alignment for all jobs Review grade assignments to ensure base pay ranges for all jobs are aligned with market practices Manage individual pay levels consistently within market-based ranges Recognize multiple career levels where consistent with market distinctions Retain existing bonus targets for roles that are currently bonus eligible and consider expanding bonus eligibility (assuming changes are made to ensure market alignment in base pay)
