Table of Contents Property and casualty contracts that are retrospectively rated contain provisions that result in an adjustment to the initial policy premium depending on the contract provisions and loss experience of the insured during the experience period. For such contracts, the Company estimates the amount of ultimate premiums that the Company may earn upon completion of the experience period and recognizes either an asset or a liability for the difference between the initial policy premium and the estimated ultimate premium. The Company adjusts such estimated ultimate premium amounts during the course of the experience period based on actual results to date. The resulting adjustment is recorded as either a reduction of or an increase to the earned premiums for the period. Claim and claim adjustment expense reserves:  Claim and claim adjustment expense reserves, except reserves for structured settlements not associated with A&EP, workers' compensation lifetime claims and long term care claims, are not discounted and are based on i) case basis estimates for losses reported on direct business, adjusted in the aggregate for ultimate loss expectations; ii) estimates of incurred but not reported (IBNR) losses; iii) estimates of losses on assumed reinsurance; iv) estimates of future expenses to be incurred in the settlement of claims; v) estimates of salvage and subrogation recoveries and vi) estimates of amounts due from insureds related to losses under high deductible policies. Management considers current conditions and trends as well as past Company and industry experience in establishing these estimates. The effects of inflation, which can be significant, are implicitly considered in the reserving process and are part of the recorded reserve balance. Ceded claim and claim adjustment expense reserves are reported as a component of Reinsurance receivables on the Consolidated Balance Sheets. Claim and claim adjustment expense reserves are presented net of anticipated amounts due from insureds related to losses under deductible policies of $1.2 billion as of December 31, 2019 and 2018. A significant portion of these amounts are supported by collateral. The Company has an allowance for uncollectible deductible amounts, which is presented as a component of the allowance for doubtful accounts included in Insurance receivables on  the Consolidated Balance Sheets. Structured settlements have been negotiated for certain property and casualty insurance claims. Structured settlements are agreements to provide fixed periodic payments to claimants. The Company's obligations for structured settlements not funded by annuities are included in claim and claim adjustment expense reserves and carried at present values determined using interest rates ranging from 5.5% to 7.6% and 5.5% to 8.0% as of December 31, 2019 and 2018. As of December 31, 2019 and 2018, the discounted reserves for unfunded structured settlements were $497 million and $512 million, net of discount of $724 million and $760 million. For the years ended December 31, 2019, 2018 and 2017, the amount of interest recognized on the discounted reserves of unfunded structured settlements was $36 million, $40 million and $41 million, respectively. This interest accretion is presented as a component of Insurance claims and policyholders’ benefits on the Consolidated Statements of Operations, but is excluded from the Company’s disclosure of prior year loss reserve development. Workers' compensation lifetime claim reserves are calculated using mortality assumptions determined through statutory regulation and economic factors. At December 31, 2019 and 2018, workers' compensation lifetime claim reserves are discounted at a 3.5% interest rate. As of December 31, 2019 and 2018, the discounted reserves for workers’ compensation lifetime claim reserves were $293 million and $343 million, net of discount of $135 million and $168 million. For the years ended December 31, 2019, 2018 and 2017, the amount of interest accretion recognized on the discounted reserves of workers’ compensation lifetime claim reserves was $21 million, $16 million and $19 million, respectively. This interest accretion is presented as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations, but is excluded from the Company's disclosure of prior year loss reserve development. Long term care claim reserves are calculated using mortality and morbidity assumptions based on Company and industry experience. Long term care claim reserves are discounted at a weighted average interest rate of 5.9% and 6.0% as of December 31, 2019 and 2018. As of December 31, 2019 and 2018, such discounted reserves totaled $2.7 billion and $2.6 billion, net of discount of $462 million and $460 million. 61
