Segment information. Prior to 2016, the Company reported three operating segments: title insurance and related services (title), mortgage services and corporate. Effective in the first quarter 2016, as a result of realigning and streamlining the management of the mortgage services operations, the Company began reporting two operating segments: title and ancillary services and corporate. The centralized title services business, previously included in the mortgage services segment, is now included in the title segment. The remaining operations of the mortgage services segment, principally search and valuation services, are not material, in the aggregate, for separate segment presentation and are now included in the ancillary services and corporate segment. In addition, the Company began allocating the costs of its centralized administrative services departments to the respective operating businesses. The operating segments reflect the current manner that management uses in allocating resources and assessing performance of the Company's businesses.

The title segment provides services needed to transfer title to property in a real estate transaction and includes services such as searching, examining, closing and insuring the condition of the title to the property. In addition, the title segment includes centralized title services, home and personal insurance services and Section 1031 exchanges. The ancillary services and corporate segment historically provided search and valuation services, loan file review, quality control services, government services, document management, recording and call center-related services offered to large mortgage lenders and servicers, mortgage brokers and mortgage investors. Beginning in 2017, the principal offering of ancillary services are search and valuation services. Also included in the ancillary services and corporate segment are expenses of the parent holding company and certain other enterprise-wide overhead costs, net of centralized administrative services costs allocated to respective operating businesses.

In 2015, management determined a goodwill impairment of $35.7 million related to the ancillary services reporting unit and presented as impairment of goodwill in the 2015 consolidated statement of operations and comprehensive loss. As a result of the Company's realignment of its operating segments, as discussed above, an impairment of $1.6 million related to the centralized title services business was subsequently included as part of the title segment.

The Company does not provide asset information by reportable operating segment as it does not routinely evaluate the asset position by segment.
