Reserves for Losses and Loss Adjustment Expenses | Reserves for Losses and Loss Adjustment Expenses The Company presents its loss development on a consolidated basis; however, it evaluates net ultimate loss and LAE under three sub-categories: multiline solutions, short tail/monoline specialty lines and exited lines. The Company has chosen to disaggregate its short-duration loss disclosures in this manner as to not obscure useful information by otherwise aggregating items with significantly different characteristics. A description of the factors the Company considered in its disaggregation by sub-category is as follows: Short tail/monoline specialty lines Short tail/monoline specialty lines includes those market niches for which the Company serves with monoline solutions which generally have shorter durations for losses to fully develop. Losses for these lines are generally reported within a short period of time from the date of loss, and in most instances, claims are settled and paid within a relatively short timeframe. Short tail/monoline specialty can be impacted by larger losses which can be more complex due to factors such as difficulty determining actual damages, legal and regulatory impediments potentially extending the period of time it takes to settle and pay claims. Multi-line Solutions Multi-line solutions includes those market niches for which the Company provides multiple products most frequently as an integrated solution. The multi-line solution subcategory is made up predominantly of occurrence liability including general liability, excess liability, and commercial auto. Multi-line solutions have a longer duration for losses to fully develop compared to short-tail/monoline specialty lines. Due to the unique claim characteristics of each product and the longer-tail nature of the multi-line solutions, this introduces more uncertainty as over time the claims can be impacted by changes in regulation, inflation and other unforeseen factors. Exited lines Exited lines includes all underwriting divisions which the Company has placed in run-off and are presented separately from lines that it currently underwrites. The reconciliation of unpaid losses and loss adjustment expenses as reported in the consolidated balance sheets for the years ended December 31, 2022 and 2021 is as follows: ($ in thousands) 2022 2021 Reserves for losses and LAE, beginning of period $ 979,549 $ 856,780 Less: reinsurance recoverable on unpaid claims, beginning of period (381,338) (375,178) Reserves for losses and LAE, beginning of period, net of reinsurance 598,211 481,602 Incurred, net of reinsurance, related to: Current period 393,939 338,348 Prior years 14,385 28,000 Total incurred, net of reinsurance 408,324 366,348 Paid, net of reinsurance, related to: Current period 105,928 77,551 Prior years 194,836 172,188 Total paid 300,764 249,739 Net reserves for losses and LAE, end of period 705,771 598,211 Plus: reinsurance recoverable on unpaid claims, end of period 435,986 381,338 Reserves for losses and LAE, end of period $ 1,141,757 $ 979,549 During the year ended December 31, 2022, the Company’s net incurred losses for accident years 2021 and prior developed adversely by $14.4 million which was related to losses subject to the LPT. Within exited lines, adverse development of $14.5 million was from the 2019 accident year primarily driven by increased frequency and severity in general and professional liability. The remaining $8.4 million of net adverse development was from various other accident years. Within multi-line solutions, favorable development of $10.8 million was from the 2020 through 2021 accident years and was primarily driven by a reduction in frequency of claims in commercial auto and general liability. The remaining $2.3 million of net adverse development was from various other accident years. There was no net development in short tail/monoline specialty lines. During the year ended December 31, 2021, the Company’s net incurred losses and LAE for accident years 2020 and prior developed adversely by $28.0 million driven by $28.8 million of adverse development in exited lines and $4.8 million of adverse development in multi-line solutions, partially offset by $5.6 million of favorable development in short tail lines. Within exited lines, the $28.8 million of adverse development was primarily related to the 2013, 2015, and 2018 accident years and was predominantly driven by increases in both frequency and severity of losses in general liability. Within multi-line solutions, adverse development of $4.8 million was primarily related to the 2016 and 2017 accident years and was driven by increased frequency and severity of claims in commercial auto. Partially offsetting the adverse development was favorable development of $5.6 million within short tail lines, primarily related to the 2019 and 2020 accident years, driven by favorable loss emergence relative to actuarial expectations in property and accident & health. Short Duration Contract Disclosures Losses and LAE reserves represent the Company’s best estimate of the ultimate net cost of all reported and unreported losses that are unpaid as of the balance sheet dates. The Company’s estimated reserves for losses and LAE include the accumulation of estimates for claims reported and unpaid prior to the balance sheet dates, estimates (based on projections of relevant historical data) of increases in claims costs for claims already reported, of claims incurred but not reported, and estimates of expenses for investigating and adjusting all incurred and unpaid claims. In determining the cumulative number of reported claims, the Company measures claim counts by incident. The claim counts include all claims reported, even if the Company does not establish a liability for the claim (i.e. reserve for loss and loss adjustment expenses).
