Scope of Analysis

* Estimated unpaid losses and allocated loss
adjustment expense (ALAE) as of June 30, 2022
for accidents occurring between January 1, 2003
and June 30, 2022 at an actuarial central
estimate and various probability levels

* Projected ultimate losses and ALAE for policy
period July 1, 2022 — 2023 at an actuarial central
estimate and various probability levels

Important Assumptions

* All estimates are limited to the City’s self-insured
retentions, which increased from $500,000 to
$600,000 per-occurrence effective 7/1/12, to
S1M for police / fire effective 7/1/15, to $1.25M
for police / fire effective 7/1/18, to $750,000 /
$2.25M effective 7/1/20, $1M / $3M effective
7/1/21 and to $1.5M / $3M effective 7/1/22.

Key Findings

* The unpaid estimate has increased by
approximately $50K due to the addition of the
7/1/21-22 policy year (at an increased retention
level, and already with a $1.5M claim), offset by
decreases in prior periods

* The forecast for 22/23 is up 5.7% from the prior
forecast due to increases in payroll and the
retained limits offset by a reduction in our
estimated base rate per payroll.
