Unpaid Policy Claims and Claims Adjustment Expense, Policy	Policy Benefits and Claims The Company maintains loss reserves to cover its estimated liability for unpaid losses and loss adjustment expenses, where material, including legal, other fees, and costs not associated with specific claims but related to the claims payment function), for reported and unreported claims incurred as of the end of each accounting period. These loss reserves are based on actuarial assumptions and are maintained at levels that are in accordance with U.S. GAAP. Many factors could affect these reserves, including economic and social conditions, frequency and severity of claims, medical trend resulting from the influences of underlying cost inflation, changes in utilization and demand for medical services, and changes in doctrines of legal liability and damage awards in litigation. Therefore, the Company’s reserves are necessarily based on estimates, assumptions and analysis of historical experience. The Company’s results depend upon the variation between actual claims experience and the assumptions used in determining reserves and pricing products. Reserve assumptions and estimates require significant judgment and, therefore, are inherently uncertain. The Company cannot determine with precision the ultimate amounts that will be paid for actual claims or the timing of those payments. The Company's estimate of loss represents management's best estimate of the Company's liability at the balance sheet date. Policy benefits and claims for the Company’s group disability products are developed using actuarial principles and assumptions that consider, among other things, future offsets and recoveries, elimination periods, interest rates, probability of rehabilitation or mortality, incidence and termination rates based on the Company’s experience. The liability for policy benefits and claims is made up of case reserves, IBNR and reopen reserves and Loss Adjustment Expenses (“LAE”). IBNR and reopen reserves are calculated by a hind-sight study, which takes historical experience and develops the reserve as a percentage of premiums from prior years. The two “primary” assumptions on which group disability reserves are based are: (i) morbidity levels; and (ii) recovery rates. If morbidity levels increase, for example due to an epidemic or a recessionary environment, the Company would increase reserves because there would be more new claims than expected. In regard to the assumed recovery rate, if disabled lives recover more quickly than anticipated then the existing claims reserves would be reduced; if less quickly, the existing claims reserves would be increased. Due to the long-term nature of LTD, in establishing the liability for policy benefits and claims, the Company must make estimates for case reserves, IBNR, and reserves for LAE. Case reserves generally equal the actuarial present value of the liability for future benefits to be paid on claims incurred as of the balance sheet date. The IBNR reserve is established based upon historical trends of existing incurred claims that were reported after the balance sheet date. The LAE reserve is calculated based on an actuarial expense study. There have been no significant changes to methodologies and assumptions from the prior year. *Medical Stop-Loss* Due to the sale of Risk Solutions, the Medical Stop-Loss segment is in run-off. The Company has $2.3 million in reserves at December 31, 2017. Liabilities for policy benefits and claims on medical stop-loss coverage are computed using completion factors and expected Net Loss Ratios derived from actual historical premium and claim data. Policy benefits and claims for medical stop-loss insurance are more volatile in nature than those for specialty health medical insurance. This is primarily due to the excess nature of medical stop-loss, with very high deductibles applying to specific claims on any individual claimant and in the aggregate for a given group. The level of these deductibles makes it more difficult to predict the amount and payment pattern of such claims. Furthermore, these excess claims are highly sensitive to changes in factors such as medical trend, provider contracts and medical treatment protocols, adding to the difficulty in predicting claim values and estimating reserves. Also, because medical stop-loss is in excess of an underlying benefit plan, there is an additional layer of claim reporting and processing that can affect claim payment patterns. Finally, changes in the distribution of business by effective month can affect reserve estimates due to the timing of claim occurrences and the time required to accumulate claims against the stop-loss deductible. Predicting ultimate claims and estimating reserves in Medical Stop-Loss is more complex than specialty health medical and disability business due to the “excess of loss” nature of these products with very high deductibles applying to specific claims on any individual claimant and in the aggregate for a given group. The level of these deductibles makes it more difficult to predict the amount and payment pattern of such claims. Fluctuations in results for specific coverage are primarily due to the severity and frequency of individual claims, whereas fluctuations in aggregate coverage are largely attributable to frequency of underlying claims rather than severity. Liabilities for first dollar medical reserves and disability coverages are computed using completion factors and expected Net Loss Ratios derived from actual historical premium and claim data. Due to the short-term nature of Medical Stop-Loss, redundancies or deficiencies will typically emerge during the course of the following year rather than over a number of years. For Medical Stop-Loss, as noted above, the Company maintains its reserves based on underlying assumptions until it determines that an adjustment is appropriate based on emerging experience from all of its prior underwriting years. Management believes that the Company's methods of estimating the liabilities for policy benefits and claims provided appropriate levels of reserves at December 31, 2017. Changes in the Company's policy benefits and claims estimates are generally recorded through a charge or credit to its earnings. There have been no significant changes to methodologies and assumptions from the prior year.
