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 Six Months Ended June 30,
(in millions)	2022		2021
U.S. Operations	$	11.7	$	(0.9)
International Operations	5.2		(1.9)
Run-off Lines	2.8		2.6
Total (favorable) unfavorable prior-year development	$	19.7	$	(0.2)

The following describes the primary factors behind each segment’s prior accident year reserve development for the six months ended June 30, 2022 and 2021:

Six months ended June 30, 2022:

•U.S. Operations: Unfavorable development primarily related to liability, including the impact of large losses, and professional lines, partially offset by favorable development in property and specialty lines.

•International Operations: Unfavorable development primarily related professional and liability losses in our Bermuda insurance operations partially offset by favorable development from Syndicate 1200 property and liability lines.

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

Six months ended June 30, 2021:

•U.S. Operations: Favorable development primarily in specialty lines, partially offset by unfavorable development in liability and professional lines.

•International Operations: Favorable development in property lines, including losses associated with prior year catastrophe losses, partially offset by unfavorable development in Argo Insurance Bermuda due to large claim movements and unfavorable development in our surety business in Europe.

•Run-off Lines: Unfavorable loss reserve development in other run-off lines.

In the opinion of management, 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.
