Description of the Company	Description of the Company We are a leading global property information, analytics and data-enabled services provider operating in North America, Western Europe and Asia Pacific. Our combined data from public, contributory and proprietary sources provides detailed coverage of property, mortgages and other encumbrances, property risk and replacement cost, consumer credit, tenancy, location, hazard risk and related performance information. We have more than one million users who rely on our data and predictive decision analytics to reduce risk, enhance transparency and improve the performance of their businesses. With our data as a foundation, we have built strong analytics capabilities and a variety of value-added business services to meet our clients’ needs for mortgage and automotive credit reporting, property tax, property valuation, tenancy, hazard risk, property risk and replacement cost, flood plain location determination and other geospatial data, analytics and related services. Clients rely on us to help identify and manage growth opportunities, improve performance and mitigate risk. We are also a party to various joint ventures under which we share control of the management of the operations with the other partner. We were originally incorporated in California in 1894, and were reincorporated in Delaware on June 1, 2010 immediately following a transaction that spun-off our financial services businesses, which we refer to as "the Separation" as more fully described below. Before June 1, 2010, we operated as The First American Corporation (“First American” or “FAC”). In connection with the Separation, we changed our name to CoreLogic, Inc. and began trading on the New York Stock Exchange under the symbol “CLGX.” As used herein, the terms "CoreLogic," the Company," "we," "our" and "us" refer to CoreLogic, Inc. and our consolidated subsidiaries, except where it is clear that the terms mean only CoreLogic, Inc. and not our subsidiaries. Reporting Segments In December 2015, we renamed our Data & Analytics segment to Property Intelligence ("PI") to reflect the broad and unique nature of the property-level insights provided by these businesses. Also, we renamed our Technology and Processing Solutions segment to Risk Management and Work Flow ("RMW") in order to reflect the current mix of risk management and underwriting-focused solutions provided by these businesses. In addition, we transferred our multifamily services business from our PI segment to RMW segment and relocated our solutions express business and consolidated our advisory services businesses under our PI segment. The changes above represent changes in our management structure and internal reporting. All segment reporting disclosures presented herein reflect these changes. Separation Transaction On June 1, 2010, we completed the Separation under which we spun-off our financial services businesses into a new, publicly-traded, New York Stock Exchange-listed company called First American Financial Corporation (“FAFC”) through a distribution (the “Distribution”) of all of the outstanding shares of FAFC to the holders of our common shares, par value $1.00 per share, as of May 26, 2010. After the Distribution, we retained the information solutions businesses which we renamed CoreLogic Inc. as noted above. To effect the Separation, we entered into a Separation and Distribution Agreement (the “Separation and Distribution Agreement”) that governs the rights and obligations of the Company and FAFC regarding the Distribution. It also governs the on-going relationship between the Company and FAFC subsequent to the completion of the Separation and provides for the allocation of assets and liabilities between FAFC and the Company. In addition, we also entered into a Tax Sharing Agreement (the “Tax Sharing Agreement”) as described in Note 9 – Income Taxes. While we are a party to the Separation and Distribution Agreement and various other agreements relating to the Separation, we have determined that we have no material continuing involvement in the operations of FAFC.
