The Hanover Insurance Group, Inc. ("THG") is a holding company organized as a Delaware corporation in 1995. We trace our roots to as early as 1852, when the Hanover Fire Insurance Company was founded. Our primary business operations are property and casualty insurance products and services. We market our products and services through independent agents and brokers in the United States ("U.S."). Our consolidated financial statements include the accounts of THG; The Hanover Insurance Company ("Hanover Insurance") and Citizens Insurance Company of America ("Citizens"), which are our principal property and casualty subsidiaries; and other insurance and non-insurance subsidiaries. Our results of operations also include the results of our discontinued operations, consisting primarily of our former Chaucer international business, as well as our former accident and health, and life insurance businesses. As discussed further in "Discontinued Operations" below, on December 28, 2018, we completed the sale of Chaucer Holdings Limited, the major portion of our Lloyd's international specialty business, to China Reinsurance (Group) Corporation ("China Re"). We subsequently completed the sale of our Chaucer-related Irish entity on February 14, 2019. The sale of the Australian entities is pending, subject only to local regulatory approval, and is expected to close in the first quarter of 2019.
We conduct our business operations through three operating segments. These segments are Commercial Lines, Personal Lines, and Other. We report interest expense related to our corporate debt separately from the earnings of our operating segments.
Information with respect to each of our segments is included in "Results of Operations - Segments" in Management's Discussion and Analysis of Financial Condition and in Note 14 - "Segment Information" in the Notes to Consolidated Financial Statements.
