[1] In establishing property and casualty reserves, the Company initially reserves for losses at the higher end of the reasonable range if no other value within the range is determined to be more probable. Selection of such an initial loss estimate is an attempt by management to give recognition that initial claims information received generally is not conclusive with respect to legal liability, is generally not comprehensive with respect to magnitude of loss and generally, based on historical experience, will develop more adversely as time passes and more information becomes available. However, as a result, the Company generally experiences reserve redundancies when analyzing the development of prior year losses in a current period.

[2] The prior accident year development for other life and health insurance products was primarily due to poor morbidity and mortality. Although the determination of the unfavorable development is subject to variability due to lower volume of other life and health business and therefore a lower credibility of claims, influenza, the usual driver of elevated morbidity and mortality in winter, was significantly higher than in the previous year and ultimately had an unfavorable effect on the Company's loss patterns.
