For the three months ended March 31, 2022, refer to the sale of Argo Seguros in Note 1, “Business and Significant Accounting Policies” for additional information.

(2)In connection with the sale of AUA, the Company entered into two retroactive reinsurance agreements with AUA subsidiaries.

(3)Amount represents the change in reserves due to changing our participation in Syndicates 1200 and 1910. For the three months ended March 31, 2023, the balance has been reduced to zero as a result of the sale of AUA.

Reserves for losses and LAE represent the estimated indemnity cost and related adjustment expenses necessary to investigate and settle claims. Such estimates are based upon individual case estimates for reported claims, estimates from ceding companies for reinsurance assumed and actuarial estimates for losses that have been incurred but not yet reported to the insurer. Any change in probable ultimate liabilities is reflected in current operating results.

The impact from the (favorable) unfavorable development of prior accident years’ loss and LAE reserves on each reporting segment is presented below:


	For the Three Months Ended March 31,
(in millions)	2023		2022
U.S. Operations	$	39.7	$	5.0
International Operations	7.8		(3.0)
Run-off Lines	1.1		1.4
Total (favorable) unfavorable prior-year development	$	48.6	$	3.4

The following describes the primary factors behind each segment’s net prior accident year reserve development for the three months ended March 31, 2023 and 2022:

Three months ended March 31, 2023:

•U.S. Operations: Net unfavorable development primarily related to liability and professional lines. The liability lines development was driven by businesses we have exited. The professional lines development was driven by accident years 2019 and prior.

•International Operations: Net unfavorable development primarily related to movements on claims in professional lines in Argo Insurance Bermuda.

•Run-off Lines: Net unfavorable loss reserve development on prior accident years in other run-off lines.

Three months ended March 31, 2022:

•U.S. Operations: Net unfavorable development primarily related to liability lines, including the impact of large losses, partially offset by net favorable development in specialty lines.

•International Operations: Net favorable development primarily related to catastrophe losses and Europe liability losses partially offset by unfavorable development in liability and professional losses from our Bermuda insurance operations.

•Run-off Lines: Net unfavorable loss reserve development on prior accident years in other run-off lines.

Our reserves represent the best estimate of our ultimate liabilities, based on currently known facts, current law, current technology and reasonable assumptions where facts are not known. Due to the significant uncertainties and related management judgments, there can be no assurance that future favorable or unfavorable loss development, which may be material, will not occur.
