Contra Costa County Retiree Health Plan
Analysis of Proposed Retiree Health Benefit Change for United Chief Officers’ Association
(UCOA) for the Contra Costa County Fire Protection District
Dear Ms. Driscoll:
As requested, we have estimated the cost impact of a proposed change to retiree health benefits for
the United Chief Officers’ Association (UCOA). The proposed benefit change would apply to all
UCOA employees and retirees for the Contra Costa County Fire Protection District (“District”). The
purpose of this analysis is to estimate the change in the County’s long-term other postemployment
liability under GASB 45 (comparison of the present value of benefits, actuarial accrued liability,
normal cost, annual required contribution, and projected benefit payments is shown before and after
the proposed change) to comply with California Government Code Section 7507.
Current Plan
Currently, for eligible Fire Management retirees represented by United Chief Officers Association
(UCOA) with bargaining unit code HA, the District will subsidize an amount equal to 80% of the
CalPERS Kaiser Bay Area premium at each coverage level (employee only, employee + one,
employee + two or more) for any region in which the retiree resides, but the District’s subsidy will not
exceed the total premium of a lower cost plan.
For retirees enrolled in a health plan from CalPERS, the District will subsidize 78% of the monthly
dental premium.
For retirees who elect dental coverage without medical coverage, the District will subsidize an
amount toward the monthly dental premium such that the retiree will pay one cent ($0.01) per month
for such coverage.
Proposed Plan
District Premium Subsidy on or after December 1, 2016: For the plan year that begins on January 1,
2017 and each calendar year thereafter, the maximum monthly premium subsidy the District will pay
for each health plan is equal to the actual dollar monthly premium subsidy that is paid by the District
for that plan as of November 30, 2016. In addition, if there is an increase in the monthly premium
charged by a health plan for 2017, the District and the employee will each pay fifty percent (50%) of
that increase. For each plan year thereafter, and for each plan, the District and the employee will
each pay fifty (50%) of the monthly premium increase above the 2016 plan premiums.

Milliman
For eligible retirees from bargaining unit HA enrolled in both a medical and dental plan, for the plan
year that begins on January 1, 2016, the District will pay a monthly premium subsidy for each dental
plan that is equal to the actual dollar monthly premium subsidy that is paid by the District as of
November 30, 2015. In addition, if there is an increase in the monthly premium charged by a dental
plan for 2016, the District and the employee will each pay fifty percent (50%) of that increase. For
each plan year thereafter, the District and the employee will each pay fifty percent (50%) of the
monthly premium increase above the 2015 plan premium.
For eligible retirees from bargaining unit HA enrolled in a dental plan only without health coverage,
beginning on January 1, 2016, the District will pay a monthly dental premium subsidy for each dental
plan that is equal to the actual dollar monthly premium subsidy that is paid by the District for 2015. If
there is an increase in the premium charged by a dental plan for 2016, the District and the employee
will each pay fifty percent (50%) of the increase. For each plan year thereafter, the District and the
employee will each pay fifty percent (50%) of the premium increase that is above the 2015 plan
premium.
Results
The results are estimated as of January 1, 2016. The estimated costs are based on valuation
results as of January 1, 2014, projected to January 1, 2016, and reflect actual health premiums for
2016. Only the liabilities for active and retired UCOA members are shown in the comparison below.

The items shown in the table above are defined as follows:
The Present Value of Benefits is the present value of projected benefits (projected claims less
retiree contributions) discounted at the valuation interest rate (5.70%).
The Actuarial Accrued Liability (AAL) is the present value of benefits that are attributed to past
service only. The portion attributed to future employee service is excluded. For retirees, this is
equal to the present value of benefits. For active employees, this is equal to the present value of
benefits prorated by service to date over service at the expected retirement age.
The Normal Cost is that portion of the District provided benefit attributable to employee service in
the current year. Employees are assumed to have an equal portion of the present value of benefits
attributed to each year of service from date of hire to expected retirement age.
The Annual Required Contribution (ARC) is equal to the Normal Cost plus an amount to amortize
the unfunded AAL as a level dollar amount over a period of 30 years on a “closed” basis starting
January 1, 2008. There are 22 years remaining as of January 1, 2016.
The table below contains a 20 year projection of projected benefit payments under the current and
proposed benefit plans for UCOA members. The projected benefit payments are net of required
retiree contributions, but include the value of the implicit premium rate subsidy for non-Medicare
retirees for whom the same premium rate is charged as for actives. The estimated projected benefit
payments are based on employees and retirees as of the valuation date. Future employees are not
reflected in the table below.

Important Notes
Except where noted above, the results in this letter are based on the same data, methods,
assumptions, and plan provisions that are used in the January 1, 2014, actuarial valuation report for
the Contra Costa County (“County”), dated August 8, 2014. Appendices A through C contain a
description of the current provisions assumptions and data used in the valuation report for UCOA
employees and retirees.
In preparing our report, we relied, without audit, on information (some oral and some in writing)
supplied by Contra Costa County’s staff. This information includes but not limited to employee census
data, financial information and plan provisions. While Milliman has not audited the financial and
census data, they have been reviewed for reasonableness and are, in our opinion, sufficient and
reliable for the purposes of our calculations. If any of this information as summarized in this report is
inaccurate or incomplete, the results shown could be materially affected and this report may need to
be revised.
All costs, liabilities, rates of interest, and other factors for the County have been determined on the
basis of actuarial assumptions and methods which are individually reasonable (taking into account the
experience of the County and reasonable expectations); and which, in combination, offer our best
estimate of anticipated experience affecting the County. Further, in our opinion, each actuarial
assumption used is reasonably related to the experience of the Plan and to reasonable expectations
which, in combination, represent our best estimate of anticipated experience for the County.
This analysis is only an estimate of the Plan’s financial condition as of a single date. It can neither
predict the Plan’s future condition nor guarantee future financial soundness. Actuarial valuations do
not affect the ultimate cost of Plan benefits, only the timing of County contributions. While the
valuation is based on an array of individually reasonable assumptions, other assumption sets may
also be reasonable and valuation results based on those assumptions would be different. No one
set of assumptions is uniquely correct. Determining results using alternative assumptions is outside
the scope of our engagement.
The estimates as of January 1, 2016, are based on actual health plan premiums for 2016, but are
based on census data and assumptions specified in the January 1, 2014, actuarial valuation. The
actual valuation results for UCOA as of January 1, 2016, will differ based on changes in census data
form 2014 and assumptions that will be established for the 2016 actuarial valuation. Furthermore,
future actuarial measurements may differ significantly from the current measurements presented in
this report due to such factors as the following: plan experience differing from that anticipated by the
economic or demographic assumptions; changes in economic or demographic assumptions;
increases or decreases expected as part of the natural operation of the methodology used for these
measurements (such as the end of an amortization period); and changes in plan provisions or
applicable law. Due to the limited scope of our assignment, we did not perform an analysis of the
potential range of future measurements. The County has the final decision regarding the
appropriateness of the assumptions and actuarial cost methods.

Appendix B. Actuarial Cost Method and Assumptions
The actuarial cost method used for determining the benefit obligations is the Projected Unit Credit
Cost Method. Under this method, the actuarial present value of projected benefits is the value of
benefits expected to be paid for current actives and eligible retirees and is calculated based on the
assumptions and census data described in this report.
The Actuarial Accrued Liability (AAL) is the actuarial present value of benefits attributed to employee
service rendered prior to the valuation date. The AAL equals the present value of benefits multiplied
by a fraction equal to service to date over service at expected retirement. The Normal Cost is the
actuarial present value of benefits attributed to one year of service. This equals the present value of
benefits divided by service at expected retirement. Since retirees are not accruing any more
service, their normal cost is zero. The actuarial value of assets is equal to the market value of
assets as of the valuation date.
In determining the Annual Required Contribution, the Unfunded AAL is amortized as a level dollar
amount over 30 years on a “closed” basis. There are 22 years remaining in the amortization period
as of January 1, 2016. The actuarial assumptions are summarized below.
Economic Assumptions
Discount Rate (Liabilities) 5.70%
We have used a discount rate of 5.70% in this valuation to reflect the County’s current policy of
partially funding its OPEB liabilities. This rate is derived based on the fund’s investment policy, level
of partial funding, and includes a 2.50% long-term inflation assumption. County OPEB Irrevocable
Trust assets are invested in the Public Agency Retirement Services’ Highmark Portfolio. Based on
the portfolio’s target allocation (shown below), the average return of Trust assets over the next 30
years is expected to be 6.25%, which would be an appropriate discount rate if the County’s annual
contribution is equal to the ARC. If the County were to elect not to fund any amount to a Trust, the
discount rate would be based on the expected return of the County’s general fund (we have
assumed a long term return of 3.50% for the County’s general fund). Since the County is partially
funding the Trust with a contribution of $20 million per year, we used a blended discount rate of
5.70%.

Valuation of Retiree Premium Subsidy Due to Active Health Costs
The California PERS (PEMHCA) health plans charge the same premiums for retirees who are not
yet eligible for Medicare as for active employees. Therefore, the retiree premium rates are being
subsidized by the inclusion of active lives in setting rates. (Premiums calculated only based on
retiree health claims experience would have resulted in higher retiree premiums.) GASB 45
requires that the value of this subsidy be recognized as a liability in valuations of OPEB costs. To
account for the fact that per member health costs vary depending on age (higher health costs at
older ages), we calculated equivalent per member per month (PMPM) costs that vary by age based
on the age distribution of covered members, and based on relative cost factors by age. The relative
cost factors were developed from the Milliman Health Cost GuidelinesTM. Based on the carrier
premium rates and relative age cost factors assumptions, we developed age adjusted monthly
PMPM health costs for 2014 to be used in valuing the implicit rate subsidy. The following tables
show the age adjusted expected monthly claims cost for a male participant at age 64 for each health
plan and relative age factors compared to a male age 64.

64 1.000 0.915
Since retirees eligible for Medicare (age 65 and beyond) are enrolled in Medicare supplemental plans,
the premiums for retirees with Medicare are determined without regard to active employee claims
experience and no such subsidy exists for this group for medical cost.

Medical Cost Inflation Assumption
We assumed future increases to the health costs and premiums are based on the “Getzen” model
published by the Society of Actuaries for purposes of evaluating long term medical trend. Under the
Patient Protection and Affordable Care Act of 2010, a Federal excise tax will apply for high cost
health plans beginning in 2018. A margin to reflect the impact of the excise tax in future years is
reflected in the assumed trend. The following table shows the assumed rate increases in future
years for Medical premiums.

Contra Costa County Retiree Health Plan
Analysis of Proposed Retiree Health Benefit Change for International Association of
Firefighters Local 1230 of the Contra Costa County Fire Protection District
Dear Ms. Driscoll:
As requested, we have estimated the cost impact of a proposed change to retiree health benefits for
the International Association of Firefighters Local 1230 (“Local 1230”). The proposed benefit
change would apply to all Local 1230 employees and retirees for the Contra Costa County Fire
Protection District (“District”). The purpose of this analysis is to estimate the change in the District’s
long-term other postemployment liability under GASB 45 (comparison of the present value of
benefits, actuarial accrued liability, normal cost, annual required contribution, and projected benefit
payments is shown before and after the proposed change) to comply with California Government
Code Section 7507.
Current Plan
Currently, for eligible retirees from bargaining unit 4N, the District will pay a subsidy toward the cost
of monthly medical premiums equal to 87% of the CalPERS Bay Area Basic Kaiser premium at
each coverage level, but not more than the actual premium, if less.
For retirees enrolled in a health plan from CalPERS, the District will also subsidize an amount equal
to 78% of the monthly dental premium. For retirees who elect dental coverage without medical
coverage, the District will subsidize an amount toward the monthly dental premium such that the
retiree will pay one cent ($0.01) per month for such coverage.
Proposed Plan
District Premium Subsidy on or after January 1, 2016: For 2016 and each calendar year thereafter,
the prior year’s District subsidy for each medical plan and rate tier will increase by 50% of the actual
premium increase in the medical plan and rate tier in which the member is enrolled.

Milliman
For eligible retirees from bargaining unit 4N enrolled in both a medical and dental plan, the District
will pay a subsidy equal to 50% of the cost of monthly dental premiums in 2016 and later. For
retirees enrolled only in a dental plan, retirees are required to pay $0.01 per month for dental
coverage. For 2016 and later, the required monthly contribution from retirees would increase each
year by 50% of the dental premium increase.

* For comparison purposes, the liabilities associated with the proposed plan change were
measured based on the 2014 premiums trended to 2015 using the trend assumption stated in
our 2014 actuarial valuation. The actual calendar year 2015 medical and dental premiums may
differ from the trended premiums and the liabilities based on actual 2015 premiums may also
differ than the amounts shown above.
The items shown in the table above are defined as follows:
The Present Value of Benefits is the present value of projected benefits (projected claims less
retiree contributions) discounted at the valuation interest rate (5.70%).
The Actuarial Accrued Liability (AAL) is the present value of benefits that are attributed to past
service only. The portion attributed to future employee service is excluded. For retirees, this is
equal to the present value of benefits. For active employees, this is equal to the present value of
benefits prorated by service to date over service at the expected retirement age.
The Normal Cost is that portion of the District provided benefit attributable to employee service in
the current year. Employees are assumed to have an equal portion of the present value of benefits
attributed to each year of service from date of hire to expected retirement age.

The Annual Required Contribution (ARC) is equal to the Normal Cost plus an amount to amortize

In preparing our report, we relied, without audit, on information (some oral and some in writing)
supplied by Contra Costa County’s staff. This information includes but not limited to employee census
data, financial information and plan provisions. While Milliman has not audited the financial and
census data, they have been reviewed for reasonableness and are, in our opinion, sufficient and
reliable for the purposes of our calculations. If any of this information as summarized in this report is
inaccurate or incomplete, the results shown could be materially affected and this report may need to
be revised.
All costs, liabilities, rates of interest, and other factors for the District have been determined on the
basis of actuarial assumptions and methods which are individually reasonable (taking into account the
experience of the District and reasonable expectations); and which, in combination, offer our best
estimate of anticipated experience affecting the District. Further, in our opinion, each actuarial
assumption used is reasonably related to the experience of the Plan and to reasonable expectations
which, in combination, represent our best estimate of anticipated experience for the District.
This analysis is only an estimate of the Plan’s financial condition as of a single date. It can neither
predict the Plan’s future condition nor guarantee future financial soundness. Actuarial valuations do
not affect the ultimate cost of Plan benefits, only the timing of District contributions. While the
valuation is based on an array of individually reasonable assumptions, other assumption sets may
also be reasonable and valuation results based on those assumptions would be different. No one
set of assumptions is uniquely correct. Determining results using alternative assumptions is outside
the scope of our engagement.
Future actuarial measurements may differ significantly from the current measurements presented in
this report due to such factors as the following: plan experience differing from that anticipated by the
economic or demographic assumptions; changes in economic or demographic assumptions;
increases or decreases expected as part of the natural operation of the methodology used for these
measurements (such as the end of an amortization period); and changes in plan provisions or
applicable law. Due to the limited scope of our assignment, we did not perform an analysis of the
potential range of future measurements. The District has the final decision regarding the
appropriateness of the assumptions and actuarial cost methods.

Appendix B. Actuarial Cost Method and Assumptions
The actuarial cost method used for determining the benefit obligations is the Projected Unit Credit
Cost Method. Under this method, the actuarial present value of projected benefits is the value of
benefits expected to be paid for current actives and eligible retirees and is calculated based on the
assumptions and census data described in this report.
The Actuarial Accrued Liability (AAL) is the actuarial present value of benefits attributed to employee
service rendered prior to the valuation date. The AAL equals the present value of benefits multiplied
by a fraction equal to service to date over service at expected retirement. The Normal Cost is the
actuarial present value of benefits attributed to one year of service. This equals the present value of
benefits divided by service at expected retirement. Since retirees are not accruing any more
service, their normal cost is zero. The actuarial value of assets is equal to the market value of
assets as of the valuation date.
In determining the Annual Required Contribution, the Unfunded AAL is amortized as a level dollar
amount over 30 years on a “closed” basis. There are 24 years remaining in the amortization period
as of January 1, 2014. The actuarial assumptions are summarized below.
Economic Assumptions
Discount Rate (Liabilities) 5.70%
We have used a discount rate of 5.70% in this valuation to reflect the County’s current policy of
partially funding its OPEB liabilities. This rate is derived based on the fund’s investment policy, level
of partial funding, and includes a 2.50% long-term inflation assumption. County OPEB Irrevocable
Trust assets are invested in the Public Agency Retirement Services’ Highmark Portfolio. Based on
the portfolio’s target allocation (shown below), the average return of Trust assets over the next 30
years is expected to be 6.25%, which would be an appropriate discount rate if the County’s annual
contribution is equal to the ARC. If the County were to elect not to fund any amount to a Trust, the
discount rate would be based on the expected return of the County’s general fund (we have
assumed a long term return of 3.50% for the County’s general fund). Since the County is partially
funding the Trust with a contribution of $20 million per year, we used a blended discount rate of
5.70%.

Coverage Election Assumptions
Retiree Coverage – We have assumed 90% of new retirees will elect medical and dental coverage at
retirement. For new retirees who were members of certain bargaining units indicated in appendix A
and hired after a certain date indicated (eligible retirees must pay entire cost of premium to maintain
coverage), we have assumed 50% will elect medical and dental coverage at retirement.
Spouse Coverage – We have assumed 50% of new retirees electing coverage will elect spouse
medical and dental coverage at retirement.
Spouse Age – Female spouses are assumed to be three years younger than male spouses.
Dependent Coverage – We have assumed 30% of retirees with no spouse coverage will elect
coverage for a dependent child until age 65, and 50% of retirees with spouse coverage will elect
coverage for a dependent child until age 65.
Health Plan Election – We have assumed that new retirees will remain enrolled in the same plan they
were enrolled in as actives. For actives who waived coverage, we have assumed that they will elect
Kaiser plan coverage.

Valuation of Retiree Premium Subsidy Due to Active Health Costs
The County and California PERS (PEMHCA) health plans charge the same premiums for retirees
who are not yet eligible for Medicare as for active employees. Therefore, the retiree premium rates
are being subsidized by the inclusion of active lives in setting rates. (Premiums calculated only
based on retiree health claims experience would have resulted in higher retiree premiums.) GASB
45 requires that the value of this subsidy be recognized as a liability in valuations of OPEB costs.
To account for the fact that per member health costs vary depending on age (higher health costs at
older ages), we calculated equivalent per member per month (PMPM) costs that vary by age based
on the age distribution of covered members, and based on relative cost factors by age. The relative
cost factors were developed from the Milliman Health Cost GuidelinesTM. Based on the carrier
premium rates and relative age cost factors assumptions, we developed age adjusted monthly
PMPM health costs for 2014 to be used in valuing the implicit rate subsidy. The following tables
show the age adjusted expected monthly claims cost for a male participant at age 64 for each health
plan and relative age factors compared to a male age 64.

60 0.786 0.789
64 1.000 0.915
Since retirees eligible for Medicare (age 65 and beyond) are enrolled in Medicare supplemental plans,
the premiums for retirees with Medicare are determined without regard to active employee claims
experience and no such subsidy exists for this group for medical cost.

Medical Cost Inflation Assumption
We assumed future increases to the health costs and premiums are based on the “Getzen” model
published by the Society of Actuaries for purposes of evaluating long term medical trend. Under the
Patient Protection and Affordable Care Act of 2010, a Federal excise tax will apply for high cost
health plans beginning in 2018. A margin to reflect the impact of the excise tax in future years is
reflected in the assumed trend. The following table shows the assumed rate increases in future
years for Medical premiums.
