Reclassifications Certain reclassifications have been made to prior period financial information to conform to the current period presentation. In particular, prior period results of operations associated with the Company's Hartford Funds business have been retrospectively reclassified to discontinued operations and assets and liabilities associated with the Hartford Funds business are classified as assets and liabilities held for sale within the Corporate category.
