6.C. - Page 100 of 196 <br />CITY OF REDWOOD CITY <br />NOTES TO THE BASIC FINANCIAL STATEMENTS <br />For the Fiscal Year Ended June 30, 2020 <br />NOTE 9 — EMPLOYEE BENEFITS (CONTINUED) <br />A. Pension Plan, Continued <br />Contributions — Section 20814(C) of the California Public Employees' Retirement Law requires that the <br />employer contribution rates for all public employers be determined on an annual basis by the actuary and shall <br />be effective on the July 1 following notice of a change in the rate. Funding contributions for both Plans are <br />determined annually on an actuarial basis as of June 30 by Ca1PERS. The actuarially determined rate is the <br />estimated amount necessary to finance the costs of benefits earned by employees during the year, with an <br />additional amount to finance any unfunded accrued liability. The City is required to contribute the difference <br />between the actuarially determined rate and the contribution rate of employees. <br />Net Pension Liability: <br />The City's net pension liability for each Plan is measured as the total pension liability, less the pension plan's <br />fiduciary net position. The net pension liability of each Plan is measured as of June 30, 2019, using an annual <br />actuarial valuation as of June 30, 2018 rolled forward to June 30, 2019 using standard update procedures. A <br />summary of principal assumptions and methods used to determine the net pension liability is shown below. <br />Actuarial Assumptions — The total pension liabilities in the June 30, 2019 actuarial valuation were <br />determined using the following assumptions: <br />Valuation Date <br />Measurement Date <br />Actuarial Cost Method <br />Actuarial Assumptions: <br />Discount Rate <br />Inflation <br />Payroll Growth <br />Salary Increases <br />Investment Rate of Return <br />Mortality <br />Post Retirement Benefit Increase <br />Miscellaneous Safety <br />June 30, 2018 June 30, 2018 <br />June 30, 2019 June 30, 2019 <br />Entry -Age Normal Cost Method <br />7.500% <br />2.500% <br />2.750% <br />7.500% <br />2.500% <br />2.750% <br />Varies by Entry Age and Service <br />7.00%(1) 7.00%(1) <br />Derived using Ca1PERS' Membership Data for all <br />Funds (2). <br />The lesser of contract COLA or 2.50% until <br />Purchasing Power Protection Allowance Floor on <br />Purchasing Power applies, 2.50% thereafter. <br />(1) Net of pension plan investment and administrative expenses, including inflation. <br />(2) The probabilities of mortality are based on the 2017 Ca1PERS Experience Study for the period from <br />1997 to 2015.
