Participating Employers
Alameda County and member districts that participate in ACERA’s pension plan are referred to as participating employers. Their employees who work in retirement-eligible positions are members of ACERA and earn retirement and other benefits. Participating employers provide employer retirement contributions to ACERA’s fund and provide the employee demographic and payroll data that allows ACERA to calculate retirement benefits and run the retirement system.
Employer Contribution Rates
Employer contribution rates are recommended annually by the ACERA’s actuary in its actuarial valuation and typically vary from year-to-year. Rates depend on the level of established benefits, rate of return on investments, and the cost of administering benefits.
Members do not benefit from employer contributions until retirement—these contributions are used, along with employee contributions, to fund member retirement benefits. Employer contributions are never refundable—if a member terminates employment and elects to receive a refund of employee retirement contributions, they will not receive employer contributions made on their behalf.
Employer Contribution Rates
These are the average rates employers are paying between September 2022 and September 2023 compared with the previous year’s rates.

Pay Codes
Determine Whether Your Other Pay Codes Are Included in Your Pension Calculation
When members retire, Highest Average Monthly Salary is one of the factors in the pension formula used to calculate pension allowances. Besides gross base pay, some other pay codes—sometimes called footnotes—will be included in the salary calculation in the pension formula. The 2012 Public Employees’ Pension Reform Act (PEPRA) requires ACERA to analyze all types of pay to determine if they will be included in Highest Average Monthly Salary.
How To Use These Pay Code Lists
- Open the PDF pay code list for your employer.
- Find your pay code(s) by number or by name. (Press Ctrl+F to use the Find function to search for numbers or text.)
- Each pay code says yes or no whether it’s included in the Highest Average Monthly Salary calculation, based on your tier.
If you have questions about your pay codes/pay items/footnotes, please consult your employer’s payroll manager, as your employer is best positioned to determine whether any of the pay codes/pay items/footnotes apply to your compensation package.
