Organization and Description of Business	Organization and Description of Business Zillow Group is reimagining real estate to make it easier to unlock life’s next chapter. As the most visited real estate website in the United States, Zillow and its affiliates offer customers an on-demand experience for selling, buying, renting or financing with transparency and ease. Our portfolio of consumer brands includes Zillow Premier Agent, Zillow Home Loans, our affiliate lender, Zillow Closing Services, Zillow Rentals, Trulia, StreetEasy, HotPads and Out East. In addition, Zillow Group provides a comprehensive suite of marketing software and technology solutions for the real estate industry which include Mortech, New Home Feed and ShowingTime+, which houses ShowingTime, Bridge Interactive, dotloop and interactive floor plans. In the fourth quarter of 2021, we began to wind down the operations of Zillow Offers, our iBuying business which purchased and sold homes directly in markets across the country. The wind down was completed in the third quarter of 2022, and we have presented the financial results of Zillow Offers as discontinued operations in our consolidated financial statements for all periods presented. See Note 3 for additional information. Certain Significant Risks and Uncertainties We operate in a dynamic industry and, accordingly, can be affected by a variety of factors. For example, we believe that changes in any of the following areas could have a significant negative effect on us in terms of our future financial position, results of operations or cash flows: current and future health and stability of the economy, financial conditions, and residential housing market; changes in general economic and financial conditions (including federal monetary policy, interest rates, inflation, home price fluctuations, housing inventory, labor shortages and supply chain issues); our investment of resources to pursue strategies and develop new products and services that may not prove effective or that are not attractive for customers and real estate partners or that do not allow us to compete successfully; our compliance with multiple listing service rules and requirements to access and use listing data, and to maintain or establish relationships with listings and data providers; our ability to obtain or maintain licenses and permits to support our current and future businesses; our ability to operate and grow our mortgage origination business, including the ability to obtain sufficient financing and resell originated mortgages on the secondary market; the duration and impact of natural disasters and other catastrophic events (including public health crises) on our ability to operate, demand for our products or services or general economic conditions; our ability to realize the benefits of our past or future strategic partnerships, acquisitions, joint ventures, capital-raising activities, investments or other corporate transactions or commitments; our ability to manage advertising inventory or pricing; effectivity of our technology and information security systems, or those of third parties on which we rely; changes in laws or government regulation affecting our business; outcomes of legal proceedings; our ability to attract and retain qualified employees and key personnel; protection of customers’ information and other privacy concerns; protection of our brand and intellectual property; and intellectual property infringement and other claims, among other things.
