[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.
