Workers’ Compensation Unpaid Losses & ALAE 
Executive Summary
City of Chandler
Data evaluated as of June 30, 2025
•
Estimated unpaid losses and allocated loss 
adjustment expense (ALAE) as of June 30, 2025
for accidents occurring between January 1, 2003
and June 30, 2025 at an actuarial central 
estimate and various probability levels
•
Projected ultimate losses and ALAE for policy 
period July 1, 2025 – 2026 at an actuarial central 
estimate and various probability levels
Scope of Analysis
Important Assumptions
Key Findings
•
The unpaid estimate has decreased by approximately 
$359K due to lower-than-expected incurred 
development, particularly in the 7/1/23-24 policy 
period. Decreases in ultimates and payments made 
in prior periods more than offset an additional year 
of exposures, despite a lower level of payments than 
expected. 
•
The forecast for 25/26 has decreased by 1.0% 
relative to the prior forecast; the projected payroll 
increase was more than offset by the decrease to the 
rate per payroll (in response to the decreases in prior 
periods).
•
Actual versus Expected results reflect actual 
incurred changes in the claims from 6/30/24 to 
6/30/25 against the expected change, based on 
assumptions from the prior analysis. The chart 
above does not reflect actual incurred loss 
development of $16K in period 07/08, $29K in 
11/12, -$70K in 15/16, and $309K in 16/17
