(2)Amount represents reserves ceded under the reinsurance to close transaction with RiverStone for Lloyd’s years of account 2017 and prior, effective January 1, 2021.

(3)Amount represents the change in reserves due to changing our participation in Syndicates 1200 and 1910.

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)	2022		2021
U.S. Operations	$	5.0	$	(0.4)
International Operations	(3.0)		—
Run-off Lines	1.4		1.4
Total (favorable) unfavorable prior-year development	$	3.4	$	1.0

The following describes the primary factors behind each segment’s prior accident year reserve development for the three months ended March 31, 2022 and 2021:

Three months ended March 31, 2022:

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

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

Three months ended March 31, 2021:

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

•International Operations: Unfavorable development primarily related to a one-time accounting adjustment and large claim movements in Argo Insurance Bermuda, partially offset by favorable development in property lines, including losses associated with prior year catastrophe losses.

•Run-off Lines: Unfavorable loss reserve development on prior accident years in risk management workers compensation, other run-off lines and an individual environmental loss.

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.
