Property and casualty insurance reserves are estimated based on historical experience patterns and current economic trends. Actual loss experience and loss trends are likely to differ from these historical experience patterns and economic conditions. Loss experience and loss trends emerge over several years from the dates of loss inception. The Company monitors such emerging loss trends on a quarterly basis. Changes in such estimates are included in the Condensed Consolidated Statements of Income in the period of change. For the nine months ended September 30, 2015, the Company reduced its property and casualty insurance reserves by $16.3 million to recognize favorable development of loss and LAE reserves from prior accident years. Personal lines insurance loss and LAE reserves developed favorably by $13.5 million, and commercial lines insurance loss and LAE reserves developed favorably by $2.8 million. The commercial lines insurance loss and LAE reserve development included adverse development of $0.7 million from continuing operations and favorable development of $3.5 million from discontinued operations. Personal automobile insurance loss and LAE reserves developed favorably by $5.6 million, homeowners insurance loss and LAE reserves developed favorably by $8.8 million, and other personal lines loss and LAE reserves developed adversely by $0.9 million. Personal lines insurance loss and LAE reserves developed favorably due primarily to the emergence of more favorable loss patterns than expected for the 2013, 2012 and 2011 accident years, partially offset by the emergence of loss patterns that were worse than expected for the 2014 accident year. Note 4 - Property and Casualty Insurance Reserves (continued) For the nine months ended September 30, 2014, the Company reduced its property and casualty insurance reserves by $44.9 million to recognize favorable development of loss and LAE reserves from prior accident years. Personal lines insurance loss and LAE reserves developed favorably by $44.0 million, and commercial lines insurance loss and LAE reserves developed favorably by $0.9 million. The commercial lines insurance loss and LAE reserve development included favorable development of $0.7 million from continuing operations and favorable development of $0.2 million from discontinued operations. Personal automobile insurance loss and LAE reserves developed favorably by $26.9 million, homeowners insurance loss and LAE reserves developed favorably by $13.3 million, and other personal lines loss and LAE reserves developed favorably by $3.8 million. Personal lines insurance loss and LAE reserves developed favorably due primarily to the emergence of loss patterns that were more favorable than expected for the 2013, 2012 and 2011 accident years. The Company cannot predict whether loss and LAE reserves will develop favorably or unfavorably from the amounts reported in the Company’s Condensed Consolidated Financial Statements. The Company believes that any such development will not have a material effect on the Company’s consolidated shareholders’ equity, but could have a material effect on the Company’s consolidated financial results for a given period.
