Claim and Claim Adjustment Expense Reserves | CNA’s property and casualty insurance claim and claim adjustment expense reserves represent the estimated amounts necessary to resolve all outstanding claims, including claims that are incurred but not reported (“IBNR”) as of the reporting date. CNA’s reserve projections are based primarily on detailed analysis of the facts in each case, CNA’s experience with similar cases and various historical development patterns. Consideration is given to such historical patterns as claim reserving trends and settlement practices, loss payments, pending levels of unpaid claims and product mix, as well as court decisions, economic conditions including inflation and public attitudes. All of these factors can affect the estimation of claim and claim adjustment expense reserves. Establishing claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves for catastrophic events that have occurred, is an estimation process. Many factors can ultimately affect the final settlement of a claim and, therefore, the necessary reserve. Changes in the law, results of litigation, medical costs, the cost of repair materials and labor rates can affect ultimate claim costs. In addition, time can be a critical part of reserving determinations since the longer the span between the incidence of a loss and the payment or settlement of the claim, the more variable the ultimate settlement amount can be. Accordingly, short-tail claims, such as property damage claims, tend to be more reasonably estimable than long-tail claims, such as workers’ compensation, general liability and professional liability claims. Adjustments to prior year reserve estimates, if necessary, are reflected in the results of operations in the period that the need for such adjustments is determined. There can be no assurance that CNA’s ultimate cost for insurance losses will not exceed current estimates. Catastrophes are an inherent risk of the property and casualty insurance business and have contributed to material period-to-period Liability for Unpaid Claim and Claim Adjustment Expenses The following table presents a reconciliation between beginning and ending claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves of Other Insurance Operations. Year Ended December 31 2017 2016 2015 (In millions) Reserves, beginning of year: Gross $ 22,343 $ 22,663 $ 23,271 Ceded 4,094 4,087 4,344 Net reserves, beginning of year 18,249 18,576 18,927 Net incurred claim and claim adjustment expenses: Provision for insured events of current year 5,201 5,025 4,934 Decrease in provision for insured events of prior years (381 ) (342 ) (255) Amortization of discount 179 175 166 Total net incurred (a) 4,999 4,858 4,845 Net payments attributable to: Current year events (975 ) (967 ) (856) Prior year events (4,366 ) (4,167 ) (4,089) Total net payments (5,341 ) (5,134 ) (4,945) Foreign currency translation adjustment and other 163 (51 ) (251) Net reserves, end of year 18,070 18,249 18,576 Ceded reserves, end of year 3,934 4,094 4,087 Gross reserves, end of year $ 22,004 $ 22,343 $ 22,663 (a) Total net incurred above does not agree to Insurance claims and policyholders’ benefits as reflected in the Consolidated Statements of Income due to amounts related to retroactive reinsurance deferred gain accounting, uncollectible reinsurance and loss deductible receivables and benefit expenses related to future policy benefits, which are not reflected in the table above. Reserving Methodology In developing claim and claim adjustment expense (“loss” or “losses”) reserve estimates, CNA’s actuaries perform detailed reserve analyses that are staggered throughout the year. Every reserve group is reviewed at least once during the year. The analyses generally review losses gross of ceded reinsurance and apply the ceded reinsurance terms to the gross estimates to establish estimates net of reinsurance. In addition to the detailed analyses, CNA reviews actual loss emergence for all products each quarter. In developing the loss reserve estimates for property and casualty contracts, CNA generally projects ultimate losses using several common actuarial methods as listed below. CNA reviews the various indications from the various methods and applies judgment to select an actuarial point estimate. The indicated required reserve is the difference between the selected ultimate loss and the inception-to-date • Paid development • Incurred development • Loss ratio • Bornhuetter-Ferguson using premiums and paid loss • Bornhuetter-Ferguson using premiums and incurred loss • Frequency times severity • Stochastic modeling For many exposures, especially those that can be considered long-tail, a particular accident or policy year may not have a sufficient volume of paid losses to produce a statistically reliable estimate of ultimate losses. In such a case, CNA’s actuaries typically assign more weight to the incurred development method than to the paid development method. As claims continue to settle and the volume of paid loss increases, the actuaries may assign additional weight to the paid development method. For most of CNA’s products, even the incurred losses for accident or policy years that are early in the claim settlement process will not be of sufficient volume to produce a reliable estimate of ultimate losses. In these cases, CNA may not assign any weight to the paid and incurred development methods. CNA may use the loss ratio, Bornhuetter-Ferguson and frequency times severity methods. For short-tail exposures, the paid and incurred development methods can often be relied on sooner, primarily because CNA’s history includes a sufficient number of years to cover the entire period over which paid and incurred losses are expected to change. However, CNA may also use the loss ratio, Bornhuetter-Ferguson and frequency times severity methods for short-tail exposures. For other more complex reserve groups where the above methods may not produce reliable indications, CNA uses additional methods tailored to the characteristics of the specific situation. Future Policy Benefit Reserves Reserves for policyholder benefits for Other Insurance Operations, which primarily includes long term care, are based on actuarial assumptions which include estimates of morbidity, persistency, inclusive of mortality, discount rates, future premium rate increases and expenses over the life of the contracts. Under GAAP, the best estimates of the actuarial assumptions at the date the contract was issued are locked-in locked-in Certain claim liabilities are more difficult to estimate and have differing methodologies and considerations which are described below. Mass Tort and A&EP Reserves CNA’s mass tort and A&EP reserving methodologies are similar as both are based on detailed account reviews of large accounts with estimates based on ultimate payments considering the applicable law and coverage litigation. These reserves are subject to greater inherent variability than is typical of the remainder of CNA’s reserves due to, among other things, a general lack of sufficiently detailed data, expansion of the population being held responsible for these exposures and significant unresolved legal issues such as the existence of coverage and the definition of an occurrence. Property and Casualty Reserve Reviews CNA’s actuarial reserve analyses result in point estimates. Each quarter, the results of detailed reserve reviews are summarized and discussed with CNA’s senior management to determine management’s best estimate of reserves. CNA’s senior management considers many factors in making this decision. The factors include, but are not limited to, the historical pattern and volatility of the actuarial indications, the sensitivity of the actuarial indications to changes in paid and incurred loss patterns, the consistency of claims handling processes, the consistency of case reserving practices, changes in CNA’s pricing and underwriting, pricing and underwriting trends in the insurance market and legal, judicial, social and economic trends. CNA’s recorded reserves reflect its best estimate as of a particular point in time based upon known facts, consideration of the factors cited above and its judgment. The carried reserve differs from the actuarial point estimate as the result of CNA’s consideration of the factors noted above as well as the potential volatility of the projections associated with the specific product being analyzed and other factors affecting claims costs that may not be quantifiable through traditional actuarial analysis. Development Tables The loss reserve development tables presented herein illustrate the change over time of reserves established for claim and allocated claim adjustment expenses arising from short duration insurance contracts for certain lines of business within CNA’s Property and Casualty Operations. Not all lines of business are presented based on their context to CNA’s overall loss reserves, calendar year reserve development, or calendar year net earned premiums. Insurance contracts are considered to be short duration contracts when the contracts are not expected to remain in force for an extended period of time. The Cumulative Net Incurred Claim and Allocated Claim Adjustment Expenses tables, reading across, show the cumulative net incurred claim and allocated claim adjustment expenses relating to each accident year at the end of the stated calendar year. Changes in the cumulative amount across time are the result of CNA’s expanded awareness of additional facts and circumstances that pertain to the unsettled claims. The Cumulative Net Paid Claim and Allocated Claim Adjustment Expenses tables, reading across, show the cumulative amount paid for claims in each accident year as of the end of the stated calendar year. The Net Strengthening or (Releases) of Prior Accident Year Reserves tables, reading across, show the net increase or decrease in the cumulative net incurred accident year claim and allocated claim adjustment expenses during each stated calendar year and indicates whether the reserves for that accident year were strengthened or released. The information in the tables is reported on a net basis after reinsurance and does not include the effects of discounting. The information contained in the years preceding calendar year 2016 is unaudited. To the extent CNA enters into a commutation, the transaction is reported on a prospective basis. To the extent that CNA enters into a disposition, the effects of the disposition are reported on a retrospective basis by removing the balances associated with it. The amounts reported for the cumulative number of reported claims include direct and assumed open and closed claims by accident year at the claimant level. The number excludes claim counts for claims within a policy deductible where the insured is responsible for payment of losses in the deductible layer. Claim count data for certain assumed reinsurance contracts is unavailable. In the loss reserve development tables, IBNR includes reserves for incurred but not reported losses and expected development on case reserves. The following tables present the gross and net carried reserves: December 31, 2017 Property Other Total (In millions) Gross Case Reserves $ 6,913 $ 4,757 $ 11,670 Gross IBNR Reserves 9,156 1,178 10,334 Total Gross Carried Claim and Claim Adjustment Expense Reserves $ 16,069 $ 5,935 $ 22,004 Net Case Reserves $ 6,343 $ 3,302 $ 9,645 Net IBNR Reserves 8,232 193 8,425 Total Net Carried Claim and Claim Adjustment Expense Reserves $ 14,575 $ 3,495 $ 18,070 December 31, 2016 (In millions) Gross Case Reserves $ 7,164 $ 4,696 $ 11,860 Gross IBNR Reserves 9,207 1,276 10,483 Total Gross Carried Claim and Claim Adjustment Expense Reserves $ 16,371 $ 5,972 $ 22,343 Net Case Reserves $ 6,582 $ 3,045 $ 9,627 Net IBNR Reserves 8,328 294 8,622 Total Net Carried Claim and Claim Adjustment Expense Reserves $ 14,910 $ 3,339 $ 18,249 Net Prior Year Development Changes in estimates of claim and claim adjustment expense reserves and premium accruals, net of reinsurance, for prior years are defined as net prior year development. These changes can be favorable or unfavorable. Favorable net prior year development of $302 million, $316 million and $218 million was recorded for Property and Casualty Operations for the years ended December 31, 2017, 2016 and 2015. Favorable net prior year development of $89 million, $43 million and $50 million was recorded for Other Insurance Operations for the years ended December 31, 2017, 2016 and 2015. The favorable net prior year development for the year ended December 31, 2017 was driven by lower than expected claim severity. Premium development can occur in the Property and Casualty Operations when there is a change in exposure on auditable policies or when premium accruals differ from processed premium. Audits on policies usually occur in a period after the expiration date of the policy. The following table and discussion presents detail of the net prior year claim and claim adjustment expense reserve development in CNA’s Property and Casualty Operations: Year Ended December 31 2017 2016 2015 (In millions) Medical professional liability $ 5 $ (37 ) $ (43) Other professional liability and management liability (131 ) (130 ) Surety (84 ) (63 ) (69) Commercial auto (38 ) (46 ) (22) General liability (28 ) (33) Workers’ compensation (65 ) 150 80 Other 5 (134 ) (123) Total pretax (favorable) unfavorable development $ (308 ) $ (288 ) $ (210) 2017 Unfavorable development in medical professional liability was primarily due to continued higher than expected frequency in aging services and higher than expected severity for hospitals in recent accident years. This was partially offset by favorable development in life sciences and hospitals in prior accident years as well as favorable development related to unallocated claim adjustment expenses. Favorable development in other professional liability and management liability was primarily due to favorable settlements on closed claims and a lower frequency of large losses for accident years 2011 through 2015 for professional and management liability, lower than expected claim frequency in accident years 2012 through 2015 for professional liability and lower than expected severity in accident years 2014 through 2015 for professional liability. Favorable development in surety coverages was primarily due to lower than expected frequency of large losses in accident years 2015 and prior. Favorable development for commercial auto was primarily due to lower than expected severity in accident years 2013 through 2016, as well as a large favorable recovery on a claim in accident year 2012. Favorable development for workers’ compensation was primarily related to decreases in frequency and severity in recent accident years, partially attributable to California reforms impacting medical costs. This was partially offset by unfavorable development related to an adverse arbitration ruling on reinsurance recoverables from older accident years as well as the recognition of loss estimates associated with favorable premium development. Unfavorable development for other coverages was primarily due to higher than expected severity in accident year 2016 and higher than expected large claim frequency in the Hardy Political Risks portfolio relating largely to accident year 2016. This unfavorable development was largely offset by favorable development due to better than expected frequency in accident years 2014 through 2015, better than expected emergence in Canadian run-off 2016 Favorable development for medical professional liability was primarily due to lower than expected severities for individual health care professionals, allied facilities and hospitals in accident years 2011 and prior and better than expected severity in medical products liability in accident years 2010 through 2015. This was partially offset by unfavorable development in accident years 2012 and 2013 related to higher than expected large loss emergence in hospitals and higher than expected frequency and severity in accident years 2014 and 2015 in the aging services business. Favorable development in other professional liability and management liability was primarily due to favorable settlements on closed claims and lower than expected frequency of claims in accident years 2010 through 2014 related to professional services and financial institutions. This was partially offset by unfavorable development related to a specific financial institutions claim in accident year 2014, higher management liability severities in accident year 2015 and deterioration on credit crises-related claims in accident year 2009. Favorable development in surety coverages was primarily due to lower than expected frequency of large losses in accident years 2014 and prior. Favorable development for commercial auto was primarily due to favorable settlements on claims in accident years 2010 through 2014 and lower than expected severities in accident years 2012 through 2015. Favorable development for general liability was primarily due to better than expected claim settlements in accident years 2012 through 2014 and better than expected severity on umbrella claims in accident years 2010 through 2013. This was partially offset by unfavorable development related to an increase in reported claims prior to the closing of the three year window set forth by the Minnesota Child Victims Act in accident years 2006 and prior. Unfavorable development for workers’ compensation was primarily due to higher than expected severity for Defense Base Act contractors that largely resulted from a reduction of expected future recoveries from the U.S. Department of Labor under the War Hazard Act. Further unfavorable development was due to the impact of recent Florida court rulings for accident years 2008 through 2015. These were partially offset by favorable development related to lower than expected frequencies related to the ongoing Middle Market and Small Business results for accident years 2009 through 2014. Favorable development for other coverages was due to better than expected claim frequency and claim severity in accident years 2010 through 2015, better than expected loss frequency in accident years 2013 through 2015, better than expected severity on the December 2015 United Kingdom floods, better than expected attritional losses and large loss experience on accident years 2013 through 2015 for Hardy business and favorable settlements on claims in accident years 2013 and prior related to CNA’s Canadian package business. Additional favorable development was due to a commutation of exposures in marine run-off 2015 Overall, favorable development for medical professional liability was related to lower than expected severity in accident years 2012 and prior. Unfavorable development was recorded related to increased claim frequency and severity in the aging services business in accident years 2013 and 2014. Favorable development in other professional liability and management liability related to better than expected large loss emergence in financial institutions primarily in accident years 2011 through 2014. Additional favorable development related to lower than expected severity for professional services in accident years 2011 and prior. Unfavorable development was recorded related to increased frequency of large claims on public company management liability in accident years 2012 through 2014. Favorable development for surety coverages was primarily due to lower than expected frequency of large losses in accident years 2013 and prior. Favorable development for commercial auto was primarily due to lower than expected severity in accident years 2009 through 2014. Favorable development for general liability was primarily due to favorable settlements on claims in accident years 2010 through 2013. Unfavorable development for workers’ compensation was primarily due to higher than expected severity related to Defense Base Act contractors in accident years 2008 through 2014. Favorable development for other coverages was due to better than expected claim frequency in accident year 2014, better than expected claim emergence from 2012 and 2014 catastrophe events, better than expected large loss emergence in accident years 2012 and prior and better than expected individual large loss emergence and favorable settlements on large claims in accident years 2013 and 2014. This was partially offset by unfavorable development due to higher than expected large losses in financial institutions and political risk, primarily in accident year 2014.
