(1)Represents acquired group life and disability reserves, net, as of May 1, 2018. See Note 3 for additional information. (2)All other incurred is primarily impacted by the level of claim resolutions in the period compared to that which is expected by the reserve assumption. A negative number implies a favorable result where claim resolutions were more favorable than assumed. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the long-term life of the block of claims. It will vary from actual experience in any one period, both favorably and unfavorably. The interest rate assumption used for discounting long-term claim reserves is an important part of the reserving process due to the long benefit period for these claims. Interest accrued on prior years’ reserves has been calculated on the opening reserve balance less one-half of the prior years’ incurred claim payments at our average reserve discount rate. Long-term disability benefits may extend for many years, and claim development schedules do not reflect these longer benefit periods. As a result, we use longer term retrospective runoff studies, experience studies and prospective studies to develop our liability estimates. Long-term disability reserves are discounted using rates ranging from 3.25% to 5%. The discount rates vary by year of claim incurral.
