NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q, including Part I, Item 2 (Management’s Discussion and Analysis of Financial Condition and Results of Operations), contains forward-looking statements based on our management’s beliefs and assumptions and on information currently available to our management. Forward-looking statements include all statements that are not historical facts and generally may be identified by terms such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “would,” “project,” “plan,” “expect” or the negative or plural of these words or similar expressions.

These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those risks, uncertainties and assumptions described in Part 1,I, Item 1A (Risk Factors) in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016. 2022, including, but not limited to risks related to:
the current and future health and stability of the economy and United States residential real estate industry, including changes in inflationary conditions, interest rates, housing availability and affordability, labor shortages and supply chain issues;
our ability to manage advertising inventory and pricing and maintain relationships with our real estate partners;
our ability to establish or maintain relationships with listing and data providers, which affects traffic to our mobile applications and websites;
our ability to comply with current and future multiple listing service (“MLS”) rules and requirements;
our ability to continue to innovate and compete successfully to attract customers and real estate partners;
our ability to operate and grow Zillow Home Loans, our mortgage origination business, including the ability to obtain or maintain sufficient financing to fund its origination of mortgages, meet customers’ financing needs with its product offerings, continue to grow the origination business 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 maintain adequate security measures or technology systems, or those of third parties on which we rely, to protect data integrity and the information and privacy of our customers and other third parties;
the impact of pending or future litigation and other disputes or enforcement actions;
our ability to attract and retain a highly skilled workforce;
acquisitions, investments, strategic partnerships, capital-raising activities, or other corporate transactions or commitments by us or our competitors;

our ability to protect and continue using our intellectual property and prevent others from copying, infringing upon, or developing similar intellectual property;
our ability to comply with domestic and international laws, regulations, rules, contractual obligations, policies and other obligations, or to obtain or maintain required licenses to support our business and operations;
our ability to pay debt, settle conversions of our convertible senior notes, or repurchase our convertible senior notes upon a fundamental change;
our ability to raise additional capital or refinance on acceptable terms, or at all;
actual or anticipated fluctuations in quarterly and annual results of operations and financial position;
the assumptions, estimates and internal or third-party data that we use to calculate business, performance and operating metrics; and
volatility of our Class A common stock and Class C capital stock prices.
Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the effect of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements include Zillow Group, Inc. and its wholly-ownedwholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These condensed consolidated financial statements have been prepared in conformity with U.S.United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes included in Zillow Group, Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016,2022, which was filed with the SEC on February 7, 2017.15, 2023. The condensed consolidated balance sheet as of December 31, 2016,2022, included herein, was derived from the audited financial statements of Zillow Group, Inc. as of that date.

The unaudited condensed consolidated interim financial statements, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, necessary to present fairly our financial position as of September 30, 2017,2023 and our results of operations, comprehensive loss, and comprehensive income (loss)shareholders’ equity for the three and nine month periods ended September 30, 20172023 and 2016,2022, and our cash flows for the nine month periods ended September 30, 20172023 and 2016.2022. The results offor the three and nine month periodsmonths ended September 30, 20172023 are not necessarily indicative of the results to be expected for the year ending December 31, 2017 or2023, for any interim period, or for any other future year.

Certain reclassifications of prior period amounts have been made to conform to the current period presentation. Unless indicated otherwise, the information in the Notes to Condensed Consolidated Financial Statements relates to our continuing operations and does not include the results of discontinued operations.

There were no significant changes to the significant accounting policies disclosed in Note 2 in the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, except for the updates noted below. Such updates were made due to our determination that we have a single operating and reportable segment, as well as certain changes to how we disaggregate our revenue into categories, beginning in the first quarter of 2023.
Recoverability of Goodwill
Goodwill is measured as the excess of consideration transferred for an acquired business over the net of the acquisition date fair values of the assets acquired and the liabilities assumed, and is not amortized. We assess the impairment of goodwill at the reporting unit level on an annual basis, in our fourth quarter, or whenever events or changes in circumstances indicate that goodwill may be impaired. In our evaluation of goodwill, we initially perform a qualitative assessment to determine whether the existence of events or circumstances indicates that it is more likely than not that the carrying value of each reporting unit is greater than its fair value. If it is more likely than not that the carrying value of a reporting unit is greater than its fair value, we perform a quantitative assessment and an impairment charge is recorded in our statements of operations if the carrying value of the reporting unit exceeds its fair value.
Beginning in 2023, our chief operating decision maker, who is our chief executive officer, manages our business, makes operating decisions and evaluates operating performance on the basis of the company as a whole, instead of on a segment basis as he did prior to 2023. This aligns to our ongoing growth strategy and our intent to provide integrated customer solutions for all tasks and services related to facilitating real estate transactions. This resulted in revisions to the nature and substance of information regularly provided to and used by the chief operating decision maker. Accordingly, we have realigned our operating structure, resulting in a single operating and reportable segment. In line with this, the nature and substance of the information regularly provided to our segment manager similarly changed, and we determined that we have only one reporting unit. Because the segment change impacted the structure of our reporting units, we performed a qualitative goodwill impairment assessment immediately before and immediately after the change in reporting units. Based on those assessments, we determined it was more likely than not that the fair value of our current and legacy reporting units exceeded their respective carrying values. Therefore, we concluded that it was not necessary to perform a quantitative impairment test.
12

Revenue Recognition
We recognize revenue when or as we satisfy our performance obligations by transferring control of the promised products or services to our customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those products or services.
As a practical expedient, we do not adjust the promised amount of consideration for the effects of a significant financing component as the period between our transfer of a promised product or service to a customer and when the customer pays for that product or service is generally one year or less.
We do not disclose the transaction price related to remaining performance obligations for (i) contracts with an original expected duration of one year or less or (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for performance completed to date. The remaining duration over which we satisfy our performance obligations is generally less than one year.
We disaggregate our revenue into the following categories: Residential, Rentals, Mortgages and Other, described below.
Residential. Residential revenue includes revenue generated by our Premier Agent and new construction marketplaces, as well as revenue from the sale of advertising and business technology solutions for real estate professionals through StreetEasy for-sale product offerings and ShowingTime+.
Our Premier Agent program offers a suite of marketing and technology products and services to help real estate agents and brokers achieve their advertising goals while growing and managing their businesses and brands. All Premier Agent partners receive access to a dashboard portal on our mobile application and website that provides individualized program performance analytics, our customer relationship management tool that captures detailed information about each contact made with a Premier Agent partner through our mobile and web platforms and our account management tools. The marketing and business technology products and services promised to Premier Agent partners are delivered over time, as the customer simultaneously receives and consumes the benefit of the performance obligations.
Premier Agent advertising products, which include the delivery of validated customer connections, or leads, are primarily offered on a share of voice basis. Payment is received prior to the delivery of connections. Connections are delivered when consumer contact information is provided to Premier Agent partners. We do not promise any minimum or maximum number of connections to customers, but instead control when and how many connections to deliver based on a customer’s share of voice. We determine the number of connections to deliver to Premier Agent partners in each zip code using a market-based pricing method in consideration of the total amount spent by Premier Agent partners to purchase connections in the zip code during the month. This results in the delivery of connections over time in proportion to each Premier Agent partners’ share of voice. A Premier Agent partners’ share of voice in a zip code is determined by their proportional monthly prepaid spend in that zip code as a percentage of the total monthly prepaid spend of all Premier Agent partners in that zip code, and determines the proportion of consumer connections a Premier Agent partner receives. The number of connections delivered for a given spend level is dynamic; as demand for advertising in a zip code increases or decreases, the number of connections delivered to a Premier Agent partner in that zip code decreases or increases accordingly.
We primarily recognize revenue related to the Premier Agent products and services based on the monthly prepaid spend recognized on a straight-line basis during the monthly billing period over which the products and services are provided. This methodology best depicts how we satisfy our performance obligations to customers, as we continuously transfer control of the performance obligations to the customer over time. Given a Premier Agent partner typically prepays their monthly spend and the monthly spend is refunded on a pro-rata basis upon cancellation of the contract by a customer, we have determined that Premier Agent partner contracts are effectively daily contracts, and each performance obligation is satisfied over time as each day lapses. We have not allocated the transaction price to each performance obligation within our Premier Agent partner arrangements, as the amounts recognized would be the same irrespective of any allocation.
We also offer a pay for performance pricing model called “Flex” for Premier Agent advertising services in certain markets. Flex is available to select partners alongside our legacy market-based pricing model. With the Flex model, Premier Agent partners are provided with validated leads at no initial cost and pay a performance advertising fee only when a real estate transaction is closed with one of the leads, generally within two years. With this pricing model, the transaction price represents variable consideration, as the amount to which we expect to be entitled varies based on the number of validated leads that convert into real estate transactions and the value of those transactions. We estimate variable consideration and record revenue as performance obligations, or validated leads, are transferred. We do not believe that a significant reversal in the amount of cumulative revenue recognized will occur once the uncertainty related to the number of transactions closed is subsequently resolved. We record a contract asset for our estimate of the consideration to which we will be entitled when the right to the consideration is conditional. When the right to consideration becomes unconditional, upon the close of a real estate transaction, we reclassify amounts to accounts receivable.
13

Our new construction marketing solutions allow home builders to showcase their available inventory to home shoppers. New construction revenue primarily includes revenue generated by advertising sold to builders on a cost per residential community basis whereby we recognize revenue on a straight-line basis during the contractual period over which the communities are advertised on our mobile applications and websites. New construction revenue also includes revenue generated on a cost per impression basis whereby we recognize revenue as impressions are delivered to users interacting with our mobile applications and websites, which is the amount for which we have the right to invoice. Consideration for new construction products is billed in arrears.
StreetEasy for-sale revenue primarily consists of our pay for performance pricing model available in the New York City market for which agents and brokers are provided with leads at no initial cost and pay a performance referral fee only when a real estate purchase transaction is closed with one of the leads. Under the StreetEasy pricing model, the transaction price represents variable consideration, as the amount to which we expect to be entitled varies based on the number of leads that convert into real estate transactions and the value of those transactions. We estimate variable consideration based on the expected number of closed transactions during the period. We do not believe that a significant reversal in the amount of cumulative revenue recognized will occur once the uncertainty related to the number of transactions closed is subsequently resolved. We record a corresponding contract asset for the estimate of variable consideration for StreetEasy Experts when the right to the consideration is conditional. When the right to consideration becomes unconditional upon the close of a real estate transaction, we reclassify amounts to accounts receivable.
Our dotloop real estate transaction management software-as-a-service solution is primarily billed in advance on a monthly basis and revenue is recognized ratably over the contract period which aligns to our satisfaction of performance obligations.
ShowingTime revenue is primarily generated by Appointment Center, a software-as-a-service and call center solution allowing real estate agents, brokerages and multiple listing services to efficiently schedule real estate viewing appointments on behalf of their customers. Appointment Center revenue is primarily billed in advance on a monthly basis and recognized ratably over the contract period which aligns to our satisfaction of performance obligations.
Rentals. Rentals revenue includes the sale of advertising and a suite of tools to rental professionals, landlords and other market participants under the Zillow and StreetEasy brands. Rentals revenue includes revenue generated by advertising sold to property managers, landlords and other rental professionals on a cost per lead, lease, listing or impression basis or for a fixed fee for certain advertising packages. We recognize revenue as leads, clicks and impressions are provided to rental professionals, or as rental listings are published on our mobile applications and websites, which is the amount for which we have the right to invoice. We recognize revenue related to our fixed fee rentals product on a straight-line basis over the contract term as the performance obligations, rental listings on our mobile applications and websites, are satisfied over time based on time elapsed. The number of leases generated through our rentals pay per lease product, Zillow Lease Connect, during the period is accounted for as variable consideration, and we estimate the amount of variable consideration based on the expected number of qualified leases secured during the period. We do not believe that a significant reversal in the amount of cumulative revenue recognized will occur once the uncertainty related to the number of leases secured is subsequently resolved. We record a corresponding contract asset for the estimate of variable consideration for Zillow Lease Connect when the right to the consideration is conditional. When the right to consideration becomes unconditional upon the execution of a lease, we reclassify amounts to accounts receivable. Rentals revenue also includes revenue generated from our rental applications product, through which potential renters can submit applications to multiple properties for a flat service fee. We recognize revenue for the rental applications product on a straight-line basis during the contractual period over which the customer has the right to access and submit the rental application.
Mortgages. Mortgages revenue primarily includes revenue generated by Zillow Home Loans, our affiliated mortgage lender, and marketing products sold to mortgage professionals on a cost per lead basis, including our Custom Quote and Connect services.
Mortgage origination revenue reflects origination fees on purchase or refinance mortgages and the corresponding sale, or expected future sale, of a loan. When an interest rate lock commitment (“IRLC”) is made to a customer, we record the expected gain on sale of the mortgage, plus the estimated earnings from the expected sale of the associated servicing rights, adjusted for a pull-through percentage (which is defined as the likelihood that an interest rate lock commitment will be originated), as revenue. Revenue from loan origination fees is recognized at the time the related purchase or refinance transactions are completed, usually upon the close of escrow and when we fund the purchase or refinance mortgage loans. Once funded, mortgage loans held for sale are recorded at fair value based on either sale commitments or current market quotes and are adjusted for subsequent changes in fair value until the loan is sold. Origination costs associated with originating mortgage loans are recognized as incurred. We sell substantially all of the mortgages we originate and the related servicing rights to third-party purchasers.
14

Mortgage loans are sold with limited recourse provisions, which can result in repurchases of loans previously sold to investors or payments to reimburse investors for loan losses. Based on historical experience, discussions with our mortgage purchasers, analysis of the volume of mortgages we originated and current housing and credit market conditions, we estimate and record a loss reserve for mortgage loans held in our portfolio and mortgage loans held for sale, as well as known and projected mortgage loan repurchase requests. These have historically not been significant to our financial statements.
Zillow Group operates Custom Quote and Connect through its wholly owned subsidiary, Zillow Group Marketplace, Inc., a licensed mortgage broker. For our Connect and Custom Quote cost per lead marketing products, participating qualified mortgage professionals typically make a prepayment to gain access to consumers interested in connecting with mortgage professionals. Mortgage professionals who exhaust their initial prepayment prepay additional funds to continue to participate in the marketplace. In Zillow Group’s Connect platform, consumers answer a series of questions to find a local lender, and mortgage professionals receive consumer contact information, or leads, when the consumer chooses to share their information with a lender. Consumers who request rates for mortgage loans in Custom Quotes are presented with customized quotes from participating mortgage professionals. For our cost per lead mortgages products, we recognize revenue when a user contacts a mortgage professional through our mortgages platform, which is the amount for which we have the right to invoice.
Other. Other revenue primarily includes revenue generated from display products, which consist of graphical mobile and web advertising sold on a cost per thousand impressions or cost per click basis to advertisers promoting their brands on our mobile applications and websites. We recognize display revenue as clicks occur or as impressions are delivered to users interacting with our mobile applications or websites, which is the amount for which we have the right to invoice.
Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. On an ongoing basis, we evaluate our estimates, including those related to the accounting for certain revenue recognition,offerings, restructuring costs, amortization period and recoverability of contract cost assets, website and software development costs, recoverability of long-lived assets and intangible assets, with definite lives, share-based compensation, income taxes, the presentation of discontinued and continuing operations, business combinations and the recoverability of goodwill, among others. To the extent there are material differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected.

Reclassifications

Note 3. Discontinued Operations

Zillow Offers Wind Down
In November 2016,2021, the FASB issued guidance onBoard of Directors of Zillow Group (the “Board”) made the classificationdetermination to wind down Zillow Offers operations. This decision was made in light of home pricing unpredictability, capacity constraints and presentationother operational challenges faced by Zillow Offers that were exacerbated by an unprecedented housing market, a global pandemic and a difficult labor and supply chain environment, all of changeswhich led us to conclude that, despite its initial promise in restricted cash onearlier quarters, Zillow Offers was unlikely to be a sufficiently stable line of business to meet our goals going forward.
The wind down of Zillow Offers was completed in the statementthird quarter of cash flows. This guidance is effective2022, at which time Zillow Offers met the criteria for interim and annual reporting periods beginning after December 15, 2017, and early adoption is permitted. The adoption of this guidance requires a retrospective transition method to each period presented. We expect to adopt this guidance on January 1, 2018. We do not expectdiscontinued operations. Accordingly, we have presented the adoption of this guidance to have a material impact on our statements of cash flows.

In June 2016, the FASB issued guidance on the measurement of credit losses on financial instruments. This guidance requires the use of an expected loss impairment model for instruments measured at amortized cost. For available-for-sale debt securities, an entity is required to recognize credit losses through an allowance for credit losses rather than as a write-down. This guidance is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018. The adoption of this guidance requires a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We expect to adopt this guidance on January 1, 2020. We have not yet determined the impact the adoption of this guidance will have on our financial position, results of operations, excluding allocation of any general corporate expenses, of Zillow Offers as discontinued operations in our condensed consolidated statements of operations for the three and nine months ended September 30, 2022. No assets or cash flows.

In February 2016,liabilities were classified as discontinued operations as of December 31, 2022.

This guidance also requires more detailed disclosures to enable users of financial statements to understand the amount, timing, and uncertainty of cash flows arising from leases. This guidance is effective for interim and annual reporting periods beginning after December 15, 2018 and should be applied through a modified retrospective transition approach for leases existing at, or entered into after, the beginningline items of the earliest comparative period presenteddiscontinued operations included in the financialcondensed consolidated statements and early adoption is permitted. We expect to adopt this guidance on January 1, 2019. We anticipate this guidance will have a material impact on our financial position, primarily due to our office space operating leases, as we will be required to recognize lease assets and lease liabilities on our consolidated balance sheet. We continue to assess the potential impacts of this guidance, including the impact the adoption of this guidance will have on our results of operations for the periods presented (in millions):

The following table presents significant non-cash items and cash flows, if any.

In January 2016, the FASB issued guidance on the recognition and measurement of financial instruments. This guidance generally requires equity investments, except those accounted for under the equity method of accounting or those that result in consolidationcapital expenditures of the investee, to be measured at fair value with changes in fair value recognized in net income. This guidance also requires the separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017, early adoption is permitted, and the guidance must be applied prospectively to equity investments that exist as of the adoption date. We expect to adopt this guidance on January 1, 2018. We do not expect the adoption of this guidance to have a material impact on our financial position, results ofdiscontinued operations or cash flows.

In May 2014, the FASB issued new guidance on revenue recognition. The guidance states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The effective date of this guidance is for interim and annual reporting periods beginning after December 15, 2017, as the FASB approved an optional one-year deferral of the effective date, and the guidance must be applied retrospectively or modified retrospectively. We will adopt this guidance on January 1, 2018 using the modified retrospective transition approach. This will result in an adjustment to accumulated deficit for the cumulative effect, if any, of applyingnine months ended September 30, 2022 (in millions):

Amortization of debt discount and debt issuance costs$21 
Loss on debt extinguishment21 
Share-based compensation16 
Inventory valuation adjustment
Depreciation and amortization
Settlement of beneficial interests in securitizations(79)
Restructuring
Restructuring costs totaled $14 million for the guidance as of the adoption date. Under this approach, we will not restate the prior financial statements presented. The guidance requires us to provide additional disclosures of the amount by which each financial statement line item is affected in the current reporting period during 2018 as compared to the guidance that was in effect before the change,nine months ended September 30, 2022, and an explanation of the reasons for significant changes, if any. While we continue to assess all potential impacts of this new guidance, we currently expect a significant impactwere related to the accounting for the cost of sales commissions. Under the new guidance, the cost of certain sales commissions will be recorded as an asset and recognized as an operating expense over the period that we expectZillow Offers wind down. Cumulative restructuring charges attributable to recover the costs (the average customer life). Currently we expense the cost of all sales commissions as incurred. We also continue to assess the impact of the guidance on our current product offerings. We continue to implement key control activitiescontinuing operations related to the new guidance, particularly related to evaluating the impactZillow Offers wind down as of the standard on new products or products with more than one performance obligation, the determination of average customer life, and the new disclosure requirements. Further, we have concluded that upon adoption of the new guidance, we will not need to implement new information technology systems. We continue to assess the impact the adoption of this guidance will have on our financial position, results of operations, cash flows and disclosures.

September 30, 2022 totaled $23 million.

Note 3.4. Fair Value Measurements

Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The standards also establish a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Assets and liabilities valued based on observable market data for similar instruments, such as quoted prices for similar assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity; instruments valued based on the best available data, some of which is internally developed, and considers risk premiums that a market participant would require.

We appliedapply the following methods and assumptions in estimating our fair value measurements:

Cash equivalents Cash equivalents are comprised of highly liquid investments, including money market funds and certificates of deposit, with original maturities of three months or less. The fair value measurement of money market funds is based on quoted market prices in active markets and the(Level 1). The fair value measurement of certificatesother cash equivalents is based on observable market-based inputs principally derived from or corroborated by observable market data (Level 2).
Short-term investments — The fair value measurement of depositour short-term investments is based on observable market-based inputs or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Investments — Our investments consistmeans (Level 2).

Mortgage loans held for sale The fair value measurement of thesemortgage loans held for sale is generally calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics (Level 2).
Forward contracts — The fair value of mandatory loan sales commitments and derivative instruments such as forward sales of mortgage-backed securities that are utilized as economic hedging instruments is calculated by reference to quoted prices for similar assets (Level 2).
Interest rate lock commitments — The fair value of IRLCs is calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics. Expired commitments are excluded from the fair value measurement. Since not all IRLCs will become closed loans, we adjust our fair value measurements for the estimated amount of IRLCs that will not close. This adjustment is effected through the pull-through rate, which represents the probability that an IRLC will ultimately result in a closed loan. For IRLCs that are cancelled or expire, any recorded gain or loss is reversed at the end of the commitment period (Level 3).
The pull-through rate is based on observable market-based inputs or inputs thatestimated changes in market conditions, loan stage and historical borrower behavior. Pull-through rates are derived principally from or corroborated by observable market data by correlation or other means.

directly related to the fair value of IRLCs as an increase in the pull-through rate, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the pull-through rate, in isolation, would result in a decrease in the fair value measurement. Changes in the fair value of IRLCs are included within revenue in our condensed consolidated statements of operations. The following table presents the range and weighted-average pull-through rates used in determining the fair value of IRLCs as of the dates presented:

On September 6, 2017,July 31, 2023, Zillow Group acquired Aryeo, Inc. acquired New Home Feed, Inc. (formerly known as Graphic Language, Inc.(“Aryeo”), a California corporation which operates the New Home Feed business, pursuant to an Agreementsoftware company that serves real estate photographers, in exchange for approximately $15 million in cash, net of cash acquired, and Plan380,259 shares of Mergerour Class C capital stock with a value of $20 million, for an immaterial amount. New Home Feed is a listing management technology that allows builders to input, manage and syndicate their listings acrosstotal consideration of $35 million, net of cash acquired. On September 11, 2023, Zillow Group acquired substantially all of the assets and partner sites. Our acquisitionliabilities of New Home Feed hasSpruce Holdings, Inc. and certain affiliated entities (collectively referred to as “Spruce”), a tech-enabled title and escrow platform, in exchange for approximately $19 million in cash, net of cash acquired. The acquisitions of Aryeo and Spruce have been accounted for as a business combination,combinations, and assets acquired and liabilities assumed were recorded at their preliminary estimated fair values. Goodwill represents the expected synergies from combining the acquired assets and the operations of the acquirer as well as intangible assets that do not qualify for separate recognition. Goodwill is measured as the excess of consideration transferred over the net of the fair values of the assets acquired and the liabilities assumed. Goodwill recorded in connection with the acquisition of Aryeo is not deductible for tax purposes, and goodwill recorded in connection with the acquisition of Spruce is deductible for tax purposes.
The total preliminary purchase prices have been allocated to the assets acquired and liabilities assumed, including identifiable intangible assets, based on their respective fair values at the acquisition date, as follows (in millions):

Unaudited pro forma financialearnings information for the acquisition accounted for as a business combination has not been presented as the effects were not material to our condensed consolidated financial statements.

Equity Investments

In June 2017, we purchased an equity interest in a privately held corporation for approximately $10.0 million, which is accounted for as a cost method investment and classified within other assets in the condensed consolidated balance sheet.

In October 2016, we purchased a 10% equity interest in a privately held variable interest entity within the real estate industry for $10.0 million, which is accounted for as a cost method investment and classified within other assets in the condensed consolidated balance sheet. In October 2016, we also entered into an immaterial commercial agreement with this entity. The entity is financed through its business operations. We are not the primary beneficiary of the entity, as we do not direct the activities that most significantly impact the entity’s economic performance. Therefore, we do not consolidate the entity. Our maximum exposure to loss is $10.0 million, the carrying amount of the investment as of September 30, 2017.

As there were no identified events or changes in circumstances that may have a significant adverse effect on the fair values of our cost method investments as of September 30, 2017, and it is not practicable to estimate the fair values of the investments given the fair values of the investments are not readily determinable, an estimate of the fair values of the cost method investments was not performed.

Table of 2.00% Convertible Senior Notes due 2021 (the “2021 Notes”), which amount includes the exercise in full of the $60.0 million over-allotment option, to Citigroup Global Markets Inc. as the initial purchaser of the 2021 Notes in a private offering to the initial purchaser in reliance on the exemption from the registration requirements provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”) for resale to qualified institutional buyers as defined in, and pursuant to, Rule 144A under the Securities Act. Contents
The 2021 Notes bear interest at a fixed rate of 2.00% per year, payable semiannually in arrears on June 1 and December 1 of each year, beginning on June 1, 2017. The 2021 Notes are convertible into cash, shares of our Class C capital stock or a combination thereof, at the Company’s election. The 2021 Notesour election, and may be settled as described below. They will mature on December 1, 2021,their respective maturity dates, unless earlier repurchased, redeemed or converted in accordance with their terms.

Prior tomore than 20 trading days during the close30 consecutive trading days ended September 30, 2023. Accordingly, each series of business on the business day immediately preceding September 1, 2021, the 2021 Notes areis not redeemable or convertible at the option of the holders of the 2021 Notes only under certain conditions, none of which conditions have been satisfied as of September 30, 2017. On or after September 1, 2021, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the 2021 Notes may convert their 2021 Notes at their option at the conversion rate then in effect, irrespective of these conditions. The Company will settle conversions of the 2021 Notes by paying or delivering, as the case may be, cash, shares of Class C capital stock, or a combination of cash and shares of Class C capital stock, at its election. The conversion rate will initially be 19.0985 shares of Class C capital stock per $1,000 principal amount of 2021 Notes (equivalent to an initial conversion price of approximately $52.36 per share of Class C capital stock). The conversion rate is subject to customary adjustments upon the occurrence of certain events. The Company may redeem for cash all or part of the 2021 Notes, at its option, on or after December 6, 2019, under certain circumstances at a redemption price equal to 100% of the principal amount of the 2021 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date (as defined in the indenture governing the 2021 Notes). The conversion option does not meet the criteria for separate accounting as a derivative as it is indexed to our own stock.

If the Company undergoes a fundamental change (as defined in the indenture governing the 2021 Notes), holders of the 2021 Notes may require the Company to repurchase for cash all or part of their 2021 Notes at a repurchase price equal to 100% of the principal amount of the 2021 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date (as defined in the indenture governing the 2021 Notes). In addition, if certain fundamental changes occur, the Company may be required in certain circumstances to increase the conversion rate for any 2021 Notes converted in connection with such fundamental changes by a specified number of shares of its Class C capital stock. Certain events are also considered “Events of Default,” which may result in the acceleration of the maturity of the 2021 Notes, as described in the indenture governing the notes. There are no financial covenants associated with the 2021 Notes.

We may not redeem the 2021 Notes prior to December 6, 2019. We may redeem the 2021 Notes for cash, at our option, in whole or in part on or after December 6, 2019, if the last reported sale price per share of our Class C capital stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period.

In accounting for the issuance of the 2021 Notes, the Company separated the 2021 Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component, representing the conversion option, was determined by deducting the fair value of the liability component from the par value of the 2021 Notes. The difference between the principal amount of the 2021 Notes and the liability component represents the debt discount, which is recorded as a direct deduction from the related debt liability in the consolidated balance sheet and amortized to interest expense using the effective interest method over the term of the 2021 Notes. The equity component of the 2021 Notes of approximately $91.4 million is included in additional paid-in capital in the condensed consolidated balance sheet and is not remeasured as long as it continues to meet the conditions for equity classification.

The Company incurred transaction costs of approximately $12.2 million related to the issuance of the 2021 Notes, including approximately $11.5 million in fees to the initial purchaser, which amount was paid out of the gross proceeds from the note offering. In accounting for the transaction costs, the Company allocated the total amount incurred to the liability and equity components using the same proportions as the proceeds from the 2021 Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the related debt liability in the condensed consolidated balance sheet and amortized to interest expense over the term of the 2021 Notes, and transaction costs attributable to the equity component were netted with the equity component in shareholders’ equity.

Interest expense related to the 2021 Notes for the three months ended September 30, 2017 was $6.8 million, which is comprised of approximately $4.5 millionending December 31, 2023.

For additional details related to our convertible senior notes, see Note 13 in the amortization of debt discount and debt issuance costs and $2.3 millionNotes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the contractual coupon interest. Interest expense related to the 2021 Notes for the nine months ended September 30, 2017 was $20.3 million, which is comprised of approximately $13.4 million related to the amortization of debt discount and debt issuance costs and $6.9 million for the contractual coupon interest. Accrued interest related to the 2021 Notes as of September 30, 2017 and December 31, 2016 was $3.1 million and $0.5 million, respectively, and is recorded in accrued expenses and other current liabilities in the condensed consolidated balance sheet.

The following table presents the outstanding principal amount and carrying value of the 2021 Notes as of the dates presented (in thousands):

   Outstanding

December 31, 2016

  $460,000   $(102,733  $357,267 

As of September 30, 2017, the unamortized debt discount and debt issuance costs for the 2021 Notes will be amortized to interest expense over a remaining period of approximately 50 months.

The estimated fair value of the 2021 Notes was $498.1 million and $474.2 million, respectively, as of September 30, 2017 and December 31, 2016. The estimated fair value of the 2021 Notes was determined through consideration of quoted market prices. The fair value is classified as Level 3 due to the limited trading activity for the 2021 Notes.

The Capped Call Confirmations are expected generally to reduce the potential dilution of our Class C capital stock upon any conversion of 2021 Notes and/or offset the cash payments the Company is required to make in excess of the principal amount of the 2021 Notes in the event that the market price of the Class C capital stock is greater than the strike price of the Capped Call Confirmations (which initially corresponds to the initial conversion price of the 2021 Notes and is subject to certain adjustments under the terms of the Capped Call Confirmations), with such reduction and/or offset subject to a cap based on the cap price of the Capped Call Confirmations. The Capped Call Confirmations have an initial cap price of $69.19 per share, which represents a premium of approximately 85% over the closing price of the Company’s Class C capital stock on The NASDAQ Global Select Market on December 6, 2016, and is subject to certain adjustments under the terms of the Capped Call Confirmations. The Capped Call Confirmations will cover, subject to anti-dilution adjustments substantially similar to those applicable to the 2021 Notes, the number of shares of Class C capital stock that will underlie the 2021 Notes. In addition, the Capped Call Confirmations provide for the Company to elect, subject to certain conditions, for the Capped Call Confirmations to remain outstanding (with certain modifications) following its election to redeem the 2021 Notes, notwithstanding any conversions of 2021 Notes in connection with such redemption. The Capped Call Confirmations do not meet the criteria for separate accounting as a derivative as they are indexed to our own stock. The premiums paid for the Capped Call Confirmations have been included as a net reduction to additional paid-in capital within shareholders’ equity.

Trulia’s Convertible Senior Notes due in 2020

In connection with the February 2015 acquisition of Trulia, a portion of the total purchase price was allocated to Trulia’s Convertible Senior Notes due in 2020 (the “2020 Notes”), which are unsecured senior obligations. Pursuant to and in accordance with the Merger Agreement, Zillow Group entered into a supplemental indenture in respect of the 2020 Notes in the aggregate principal amount of $230.0 million, which supplemental indenture provides, among other things, that, at the effective time of the Trulia Merger, (i) each outstanding 2020 Note is no longer convertible into shares of Trulia common stock and is convertible solely into shares of Zillow Group Class A common stock, pursuant to, and in accordance with, the terms of the indenture governing the 2020 Notes, and (ii) Zillow Group guaranteed all of the obligations of Trulia under the 2020 Notes and related indenture. The aggregate principal amount of the 2020 Notes is due on December 15, 2020 if not earlier converted or redeemed. Interest is payable on the 2020 Notes at the rate of 2.75% semi-annually on June 15 and December 15 of each year.

In December 2016, the Company used approximately $370.2 million of the net proceeds from the issuance of the 2021 Notes discussed above to repurchase $219.9 million aggregate principal of the 2020 Notes in privately negotiated transactions. The repurchase of the 2020 Notes was accounted for as a debt extinguishment, and the consideration transferred was allocated between the liability and equity components by determining the intrinsic value of the conversion option immediately prior to the debt extinguishment and allocating that portion of the repurchase price to additional paid-in capital for $127.6 million with the residual repurchase price allocated to the liability component. The partial repurchase of the 2020 Notes resulted in the recognition of a $22.8 million loss on debt extinguishment for thefiscal year ended December 31, 2016.

Holders of the 2020 Notes may convert all or any portion of their notes, in multiples of $1,000 principal amount, at their option at any time prior to the close of business on the business day immediately preceding the maturity date. Regarding the supplemental indenture in respect of the 2020 Notes, the conversion ratio immediately prior to the effective time of the Trulia Merger of 27.8303 shares of Trulia common stock per $1,000 principal amount of notes was adjusted to 12.3567 shares of our Class A common stock per $1,000 principal amount of notes based on the exchange ratio of 0.444 per the Merger Agreement. This was equivalent to an initial conversion price of approximately $80.93 per share of our Class A common stock. Regarding the August 2015 distribution of shares of our Class C capital stock as a dividend to our Class A and Class B common shareholders, the conversion ratio has been further adjusted to 41.4550 shares of Class A common stock per $1,000 principal amount of notes, which is equivalent to a conversion price of approximately $24.12 per share of our Class A common stock. The conversion ratio will be adjusted for certain dilutive events and will be increased in the case of corporate events that constitute a “Make-Whole Fundamental Change” (as defined in the indenture governing the notes). The conversion option of the 2020 Notes has no cash settlement provisions. The conversion option does not meet the criteria for separate accounting as a derivative as it is indexed to our own stock.

The holders of the 2020 Notes will have the ability to require us to repurchase the notes in whole or in part upon the occurrence of an event that constitutes a “Fundamental Change” (as defined in the indenture governing the notes, including such events as a “change in control” or “termination of trading”, subject to certain exceptions). In such case, the repurchase price would be 100% of the principal amount of the 2020 Notes plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change repurchase date. Certain events are also considered “Events of Default,” which may result in the acceleration of the maturity of the 2020 Notes, as described in the indenture governing the notes. There are no financial covenants associated with the 2020 Notes.

The 2020 Notes are redeemable, at our option, in whole or in part on or after December 20, 2018, if the last reported sale price per share of our Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period.

Interest expense related to the 2020 Notes for the three months ended September 30, 2017 and 2016 was $0.1 million and $1.6 million, respectively. Interest expense related to the 2020 Notes for the nine months ended September 30, 2017 and 2016 was $0.2 million and $4.7 million, respectively. Accrued interest related to the 2020 Notes as of September 30, 2017 and December 31, 2016 was not material.

The carrying value of the 2020 Notes was $10.1 million as of September 30, 2017 and December 31, 2016. The estimated fair value of the 2020 Notes was $17.6 million and $17.3 million, respectively, as of September 30, 2017 and December 31, 2016. The estimated fair value of the 2020 Notes was determined through consideration of quoted market prices. The fair value is classified as Level 3 due to the limited trading activity for the 2020 Notes.

Note 10. Income Taxes

We are primarily subject to federal and state income taxes in the United States (federal and in Canada. During the three and nine month periods endedstate), as well as certain foreign jurisdictions. As of September 30, 20172023 and 2016, we did not have a material amount of current taxable income, and we are not projecting a material amount of current taxable income for the year ending December 31, 2017. We2022, we have provided a full valuation allowance against our net deferred tax assets as of September 30, 2017 and December 31, 2016 because,that we believe, based on the weight of available evidence, it isare not more likely than not (a likelihood of more than 50%) that some or all of the deferred tax assets will notto be realized. Therefore, no material current tax liability or expense has been recorded in the condensed consolidated financial statements. We have accumulated federal tax losses of approximately $893.3 million$1.8 billion as of December 31, 2016,2022, which are available to reduce future taxable income. We have accumulated state tax losses of approximately $13.5$63 million (tax effected) as of December 31, 2016.

We recorded an2022.

Our income tax expense or benefit for interim periods is determined using an estimate of $1.4 millionour annual effective tax rate, adjusted for discrete items, if any, that are taken into account for the relevant period. We update our estimate of the annual effective tax rate on a quarterly basis and make year-to-date adjustments to the tax provision or benefit, as applicable. Income tax expense (benefit) for the three and nine months ended September 30, 2023 and the nine months ended September 30, 20162022 was not material. We recorded income tax expense of $3 million for the three months ended September 30, 2022, primarily duerelated to a deferred tax liability generated in connection with Zillow Group’s February 22, 2016 acquisition of Naked Apartments that can be used to realize certain deferred tax assets for which we had previously provided a full allowance.

Note 12. Share-Based Awards

In connection with our February 2015 acquisition of Trulia, we assumed the obligations of Zillow, Inc. and Trulia outstanding under pre-existing stock plans. We intend that future equity grants will be made under Zillow Group’s 2011 Amended and Restated Incentive Plan (as amended and/or restated from time to time, the “2011 Plan”) only (or a successor thereto).

Zillow Group, Inc. Amended and Restated 2011 Incentive Plan

On July 19, 2011, the 2011 Plan became effective and serves as the successor to Zillow, Inc.’s 2005 Equity Incentive Plan (the “2005 Plan”). Shareholders last approved the 2011 Plan on June 15, 2016.

In addition to the share reserve of 18,400,000 shares, the number of shares available for issuanceoption awards and restricted stock units typically granted under the 2011Zillow Group, Inc. 2020 Incentive Plan automatically increases on(the “2020 Plan”) which vest quarterly over four years, during the first dayquarter of each2023, the Compensation Committee of the Board approved option and restricted stock unit awards granted under the 2020 Plan in connection with the 2022 annual review cycle that vest quarterly over three years. The exercisability terms of these equity awards are otherwise consistent with the terms of the option awards and restricted stock units typically granted under the 2020 Plan. For additional information regarding our fiscal years by a

On August 3, 2022, upon the recommendation of (a) 3.5%the Compensation Committee, the Board approved adjustments to the exercise price of ourcertain outstanding Class A common stock, Class B common stock,vested and unvested option awards for eligible employees. The exercise price of eligible option awards was reduced to $38.78, which was the closing market price of our Class C capital stock on a fully diluted basis asAugust 8, 2022. No other changes were made to the terms and conditions of the end of our immediately preceding fiscal year, (b) 10,500,000 shares, and (c) a lesser amount determined by our board of directors; provided, however, that any shares from any increases in previous years that are not actually issued will continue to be availableeligible option awards. We have accounted for issuance under the 2011 Plan. In addition, shares previously available for grant under the 2005 Plan, but not issued or subject to outstanding awards under the 2005 Plan as of July 19, 2011, and shares subject to outstanding awards under the 2005 Plan that subsequently cease to be subject to such awards (other than by reason of exercisereprice of the awards) are available for grant undereligible option awards as an equity modification whereby the 2011 Plan. The 2011 Plan is administered byincremental fair value attributable to the compensation committee of the board of directors. Under the terms of the 2011 Plan, the compensation committee may grant equityrepriced option awards, including incentive stock options, nonqualified stock options, restricted stock, restricted stock units or restricted units to employees, officers, directors, consultants, agents, advisors and independent contractors. The board of directors has also authorized certain senior executive officers to grant equity awards under the 2011 Plan, within limits prescribed by our board of directors. The 2011 Plan provides that in the event of a stock dividend, stock split or similar event, the maximum number and kind of securities available for issuance under the plan will be proportionally adjusted.

Options under the 2011 Plan are granted with an exercise price per share not less than 100% of the fair market value of our stockas measured on the date of grant, with the exception of substitutedreprice, will be recognized as additional share-based compensation expense. The reprice impacted 7 million stock option awards, grantedaffected 3,348 employees and was expected to result in connection with acquisitions, and are exercisable at such times and under such conditions as determined by theincremental share-based compensation committee. Under the 2011 Plan, the maximum termexpense of an option is ten years from the date of grant. Any portion of an option that is not vested and exercisable on the date of a participant’s termination of service expires on such date. Employees generally forfeit their rights to exercise vested options after 3 months following their termination of employment or 12 months$66 million in the event of termination by reason of death, disability or retirement. Options granted under the 2011 Plan typically expire seven or 10 years from the grant date and typically vest either 25% after 12 months and ratably thereaftertotal over the next 36 months or quarterly over aremaining requisite service period of four years, though certainthe original awards. The weighted-average total fair value of options have been granted with alternative vesting schedules.

Restricted stock units granted under the 2011 Plan typically vest either 25% after 12 months and quarterly thereafter over the next three years or 12.5% after 6 months and quarterly thereafter for the next 3.5 years. Any portion of a restricted stock unit that is not vested on the date of a participant’s termination of service expires on such date.

In March 2016, Zillow Group established an equity choice program pursuant to which Zillow Group grants restricted stock units and option awards to acquire shares of Class C capital stock to certain employees to retain and recognize their efforts on behalf of Zillow Group.

repriced in August 2022 was $67.58.

Note 13. Net Income (Loss)Loss Per Share

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares (including Class A common stock, Class B common stock and Class C capital stock) outstanding during the period. In the calculation of basic net income (loss) per share, undistributed earnings are allocated assuming all earnings during the period were distributed.

Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares (including Class A common stock, Class B common stock and Class C capital stock) outstanding during the period and potentially dilutive Class A common stock and Class C capital stock equivalents, except in cases where the effect of the Class A common stock or Class C capital stock equivalent would be antidilutive. Potential Class A common stock and Class C capital stock equivalents consist of Class A common stock and Class C capital stock issuable upon exercise of stock options and Class A common stock and Class C capital stock underlying unvested restricted stock units using the treasury stock method. Potential Class A common stock equivalents also include Class A common stock issuable upon conversion of the 2020 Notes using the if-converted method.

Table of the outstanding 2021 Notes in cash, the Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted net income per share, if applicable. The conversion spread of approximately 8.8 million shares will have a dilutive impact on diluted net income per share when the market price of the Company’s Class C capital stock at the end of a period exceeds the conversion price of $52.36 per share for the 2021 Notes.

In the event of liquidation, dissolution, distribution of assets or winding-up of the Company, the holders of all classes of common and capital stock have equal rights to receive all the assets of the Company after the rights of the holders of preferred stock have been satisfied. We have not presented net income (loss) per share under the two-class method for our Class A common stock, Class B common stock and Class C capital stock because it would be the same for each class due to equal dividend and liquidation rights for each class.

Note 14. Commitments and Contingencies

Lease

Commitments

We have entered into various non-cancelable operating lease agreements for certain of our office space and equipment with original lease periods expiring between 2017 and 2024. We are committed to pay a portion of the related operating expenses under certain of these lease agreements. Certain of these arrangements have free rent periods or escalating rent payment provisions, and we recognize rent expense under such arrangements on a straight-line basis. Operating lease expense for

During the three months ended September 30, 2017 and 2016 was $5.7 million and $4.3 million, respectively. Operating lease expense for the nine months ended September 30, 2017 and 2016 was $15.8 million and $12.1 million, respectively.

Purchase Commitments

We have entered into various non-cancelable purchase commitments for content related to our mobile applications and websites. License agreement terms vary by vendor. In some instances, we retain perpetual rights to this information after the contract ends; in other instances, the information and data are licensed only during the fixed term of the agreement. Additionally, certain data license agreements provide for uneven payment amounts throughout the contract term.

We capitalize payments made to third parties for data licenses that we expect to provide future economic benefit through the recovery of the costs of these arrangements via the generation of our revenue and margins. For data license contracts that include uneven payment amounts, we capitalize the payments as they are made as an intangible asset and amortize the total contract value over the estimated useful life. For contracts in which we have perpetual rights2023, there were no material changes to the data and expect to utilizecommitments disclosed in Note 18 in the data beyond the life of the contract, the total contract value is amortized on a straight-line basis over the life of the contract plus two years, which is equivalentNotes to the estimated useful life of the asset. For contractsConsolidated Financial Statements included in which we either do not have access to the data beyond the contractual term or do not expect to utilize the data beyond the life of the contract, the total contract value is amortizedour Annual Report on a straight-line basis over the term of the contract. We evaluate data content contracts for potential capitalization at the inception of the arrangement as well as each time periodic payments to third parties are made.

The amortization periodForm 10-K for the capitalized purchased content is based on our best estimate of the useful life of the asset, which ranges from approximately five to nine years. The capitalized purchased data content is amortized on a straight-line basis as the pattern of delivery of the economic benefits of the data cannot reliably be determined because we do not have the ability to reliably predict future traffic to our mobile applications and websites.

Under certain other data agreements, the underlying data is obtained on a subscription basis with consistent monthly or quarterly recurring payment terms over the contractual period. Upon the expiration of such arrangements, we no longer have the right to access the related data, and therefore, the costs incurred under such contracts are not capitalized and are expensed as payments are made. We would immediately lose rights to data under these arrangements if we were to cancel the subscription and/or cease making payments under the subscription arrangements.

As of September 30, 2017, we had non-cancelable purchase commitments for content related to our mobile applications and websites totaling $144.4 million. The amounts due for this content as of September 30, 2017 are as follows (in thousands):

Letters of Credit

As of September 30, 2017, we have outstanding letters of credit of approximately $5.2 million, $1.8 million, $1.5 million and $1.1 million, respectively, which secure our lease obligations in connection with the operating leases of our San Francisco, Seattle, New York and Denver office spaces. Certain of the letters of credit are unsecured obligations, and certain of the letters of credit are secured by certificates of deposit held as collateral in our name at a financial institution. The secured letters of credit are classified as restricted cash in our consolidated balance sheet.

Surety Bonds

In the course of business, we are required to provide financial commitments in the form of surety bonds to third parties as a guarantee of our performance on and our compliance with certain obligations. If we were to fail to perform or comply with these obligations, any draws upon surety bonds issued on our behalf would then trigger our payment obligation to the surety bond issuer. We have outstanding surety bonds issued for our benefit of approximately $3.7 million and $3.6 million as of September 30, 2017 andfiscal year ended December 31, 2016, respectively.

Legal Proceedings

We are involved in a number of legal proceedings concerning matters arising in connection with the conduct of our business activities, some of which are at preliminary stages and some of which seek an indeterminate amount of damages. We regularly evaluate the status of legal proceedings in which we are involved to assess whether a loss is probable or there is a reasonable possibility that a loss or additional loss may have been incurred to determine if accruals are appropriate. We further evaluate each legal proceeding to assess whether an estimate of possible loss or range of loss can be made if accruals are not appropriate. For certain

cases described below, management is unable to provide a meaningful estimate of the possible loss or range of possible loss because, among other reasons,reasons: (i) the proceedings are in preliminary stages; (ii) specific damages have not been sought; (iii) damages sought are, in our view, unsupported and/or exaggerated; (iv) there is uncertainty as to the outcome of pending appeals or motions; (v) there are significant factual issues to be resolved; and/or (vi) there are novel legal issues or unsettled legal theories presented. For these cases, however, management does not believe, based on currently available information, that the outcomes of these proceedings will have a material effect on our financial position, results of operations or cash flow.

In March 2015, For the Wage and Hour Division of the U.S. Department of Labor (“DOL”) notified the Company that it was initiating a compliance review to determine the Company’s compliance with one or more federal labor laws enforced by the DOL. Asmatters discussed below, on May 5, 2016, Zillow, Inc. agreed to settle a class action lawsuit which alleged, among other things, claims that we failed to provide meal and rest breaks, failed to pay overtime, and failed to keep accurate records of employees’ hours worked. The settlement of the class action lawsuit, which was approved by the court on October 3, 2017, was contingent on Zillow, Inc.’s complete resolution of the DOL compliance review. On November 28, 2016, Zillow, Inc. entered into a settlement agreement with the DOL that resolved the DOL’s compliance review. Under the terms of the settlement agreement, Zillow, Inc. agreed that it will make the voluntary payments contemplated by the class action lawsuit settlement and establish and maintain certain procedures to promote future compliance with the Fair Labor Standards Act. The settlement agreement with the DOL doeshave not require Zillow, Inc. to makerecorded any payments which are in addition to those contemplated by the class action lawsuit settlement. Zillow, Inc. has not admitted liability with respect to either the DOL settlement or the class action lawsuit settlement.

In November 2014, a former employee filed a putative class action lawsuit against us in the United States District Court, Central District of California, with the caption Ian Freeman v. Zillow, Inc. The complaint alleged, among other things, claims that we failed to provide meal and rest breaks, failed to pay overtime, and failed to keep accurate records of employees’ hours worked. After the court granted our two motions to dismiss certain claims, plaintiff filed a second amended complaint that includes claims under the Fair Labor Standards Act. On November 20, 2015, plaintiff filed a motion for class certification. On February 26, 2016, the court granted the plaintiff’s motion for class certification. On May 5, 2016, the parties agreed to settle the lawsuit, which was later memorialized in a settlement agreement executed by the parties on December 2, 2016, with payment by Zillow, Inc. of up to $6.0 million. On June 9, 2016, the Ninth Circuit Court of Appeals granted our petition for permission to appeal the order granting class certification. The settlement does not contain any admission of liability, wrongdoing, or responsibility by any of the parties. On April 10, 2017, the parties executed an amendment to the settlement agreement providing that the settlement class includes all current and former inside sales consultants employed by Zillow, Inc. in (i) its California offices from November 19, 2010 through the date on which the court granted preliminary approval and (ii) its Washington offices from March 1, 2013 through the date on which the court granted preliminary approval. On May 26, 2017, the court granted preliminary approval of the settlement of the class action lawsuit, and on October 3, 2017, the court granted final approval of the settlement of the class action lawsuit. We made the voluntary payments contemplated by the class action settlement agreement in the amount of $6.0 million in October 2017. We have recorded a liability related to the settlement for $6.0 millionmaterial accruals as of September 30, 2017 and2023 or December 31, 2016. We do not believe that any additional loss will be incurred related to this matter given the court granted final approval of the settlement of the class action lawsuit in October 2017.

In July 2015, VHT, Inc. (“VHT”) filed a complaint against us in the U.S. District Court for the Western District of Washington alleging copyright infringement of VHT’s images on the Zillow Digs site. In January 2016, VHT filed an amended complaint alleging copyright infringement of VHT’s images on the Zillow Digs site as well as the Zillow listing site. In December 2016, the court granted a motion for partial summary judgment that dismissed VHT’s claims with respect to the Zillow listing site. A federal jury trial began on January 23, 2017, and on February 9, 2017, the jury returned a verdict finding that the Company had infringed VHT’s copyrights in images displayed or saved to the Digs site. The jury awarded VHT $79,875 in actual damages and approximately $8.2 million in statutory damages. In March 2017, the Company filed motions in the district court seeking judgment for the Company on certain claims that are the subject of the verdict, and for a new trial on others. On June 20, 2017, the judge ruled and granted in part our motions, finding that VHT failed to present sufficient evidence to prove direct copyright infringement for a portion of the images, reducing the total damages to approximately $4.1 million. On October 26, 2017, the Company filed an appeal with the Ninth Circuit Court of Appeals seeking review of the final judgment and certain prior rulings entered by the district court. We did not record an accrual related to this complaint as of December 31, 2016, as we did not believe a loss was probable. We have recorded an estimated liability for approximately $4.1 million as of September 30, 2017, which is classified in general and administrative expenses in our condensed consolidated statement of operations for the nine months ended September 30, 2017. We do not believe there is a reasonable possibility that a material loss in excess of amounts accrued may be incurred.

In April 2017, we received a Civil Investigative Demand from the Consumer Financial Protection Bureau (“CFPB”) requesting information related to our March 2017 response to the CFPB’s February 2017 Notice and Opportunity to Respond and Advise (“NORA”) letter. The NORA letter notified us that the CFPB’s Office of Enforcement was considering whether to recommend that the CFPB take legal action against us, alleging that we violated Section 8 of the Real Estate Settlement Procedures Act (“RESPA”) and Section 1036 of the Consumer Financial Protection Act (“CFPA”). This notice stemmed from an inquiry that commenced in 2015 when we received and responded to an initial Civil Investigative Demand from the CFPB. We continue to cooperate with the CFPB in connection with requests for information. Based on correspondence from the CFPB in August 2017, we understand that it has

concluded its investigation. The CFPB invited us to discuss a possible settlement and indicated that it intends to pursue further action if those discussions do not result in a settlement. We continue to believe that our acts and practices are lawful and that our co-marketing program allows lenders and agents to comply with RESPA, and we will vigorously defend against any allegations to the contrary. Should the CFPB commence an action against us, it may seek restitution, disgorgement, civil monetary penalties, injunctive relief or other corrective action. We cannot provide assurance that the CFPB will not commence a legal action against us in this matter, nor are we able to predict the likely outcome of any such action. As of September 30, 2017, we have recorded an accrual for an immaterial amount in connection with this matter. There is a reasonable possibility that a loss in excess of amounts accrued may be incurred; however, the possible loss or range of loss is not estimable. We did not record an accrual related to this matter as of December 31, 2016 because the possible loss or range of loss was not estimable.

On February 17, 2021, the Ninth Circuit Court of Appeals denied our petition for review of that decision. On October 21, 2022, the parties jointly filed a notice of settlement with the U.S. District Court for the Western District of Washington to inform the court that the parties have reached an agreement to settle this action. On March 31, 2023, the plaintiffs filed a motion seeking preliminary approval of the parties’ proposed settlement, which motion was granted by the court on April 3, 2023. The terms of the parties’ proposed settlement agreement are contained in the settlement documents filed with the court on March 31, 2023. The court approved the settlement terms on August 8, 2023 and the full amount was paid by our insurance carriers under the applicable insurance policy and pursuant to the terms of the settlement.

In addition to the matters discussed above, from time to time, we are involved in litigation and claims that arise in the ordinary course of business. Although we cannot be certain of the outcome of any such litigation or claims, nor the amount of damages and exposure that we could incur, we currently believe that the final disposition of such matters will not have a material effect on our business, financial position, results of operations or cash flow. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

As of September 30, 2023, we had 6,148 employees compared to 5,724 employees as of December 31, 2022.
Health of Housing Market
Our financial performance is impacted by changes in the health of the housing market, which is impacted, in turn, by general economic conditions. Current market factors have been driven by low housing inventory, fewer new for-sale listings, increases and volatility in mortgage professionals maximize business opportunitiesinterest rates, as well as home price fluctuations and connect with millions of consumers. We also own and operateinflationary conditions. These factors may have a negative impact on the number of business brandstransactions consumers complete using our products and services and on demand for our advertising services. According to industry data from the National Association of REALTORS®, total residential real estate rental and mortgage professionals, including Mortech, dotloop, Bridge Interactive and New Home Feed.

Our living database of more than 110 million U.S. homes—including homes for sale, homes for rent and homes not currently on the market—attracts an active and vibrant community of users. Individuals and businesses that use Zillow’s mobile applications and websites have updated information on more than 74 million homes, creating exclusive home profiles not available anywhere else. These profiles include detailed information about homes, including property facts, listing information and purchase and sale data. Using complex, proprietary automated valuation models, we provide current home value estimates, or Zestimates, and current rental price estimates, or Rent Zestimates, on approximately 100 million U.S. homes. We provide this information to our users where, when and how they want it, through our industry-leading mobile applications that enable consumers to access our information when they are curbside, viewing homes, and through our websites. There were approximately 175.2 million average monthly unique users of our mobile applications and websites fortransaction dollars declined 14% during the three months ended September 30, 20172023 as compared to 164.5 million average monthly unique users for the three months ended September 30, 2016, representing year-over-year2022 and more than 20% during the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022. Despite the industry headwinds and total residential real estate transaction value declines, we continue to invest in the execution of our strategy to increase customer transactions and revenue per transaction. We believe this continued investment in our strategic priorities has resulted in year over year Residential revenue results, described below, for the three and nine months ended September 30, 2023 as compared to the same periods in the prior year, that exceeded residential real estate industry performance for the same periods. The extent to which market factors impact our results and financial position will depend on future developments, which are uncertain and difficult to predict.

Acquisitions
On July 31, 2023, we acquired Aryeo, Inc. (“Aryeo”), a software company that serves real estate photographers, in exchange for total consideration of $35 million, net of cash acquired. On September 11, 2023, we acquired substantially all of the assets and liabilities of Spruce Holdings, Inc. and certain affiliated entities (collectively referred to as “Spruce”), a tech-enabled title and escrow platform, in exchange for total consideration of $19 million, net of cash acquired. Acquisition-related costs incurred, which primarily included legal, accounting and other external costs directly related to the acquisition, are included within acquisition-related costs in our condensed consolidated statements of operations and were expensed as incurred.
On October 28, 2023, Zillow, Inc. and Enchant, LLC, d/b/a Follow Up Boss (“Follow Up Boss”), entered into a Membership Interest Purchase Agreement (the “Agreement”), pursuant to which Zillow, Inc. agreed to acquire Follow Up Boss for $400 million in cash, subject to certain adjustments, payable upon closing of the transaction, and up to $100 million in cash payable over a three-year period upon achievement of certain performance metrics contemplated by the Agreement. Follow Up Boss is a customer relationship management system for real estate professionals.
Discontinued Operations
In the fourth quarter of 2021, the Board of Directors of Zillow Group (the “Board”) made the determination to wind down the operations of Zillow Offers, our iBuying business which purchased and sold homes directly in certain markets across the United States. The wind down was completed in the third quarter of 2022 and resulted in approximately a 25% reduction of Zillow Group’s workforce. The financial results of Zillow Offers have been presented in the accompanying condensed

consolidated financial statements as discontinued operations and, therefore, are excluded from the following discussion of the results of our continuing operations. Given the wind down of Zillow Offers and corresponding shift in our strategic plans, financial performance for prior and current periods may not be indicative of future performance. For additional information, see Note 3 in our Notes to the Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q.
August 2022 Equity Award Actions
On August 3, 2022, upon the recommendation of the Compensation Committee of the Board, the Board approved adjustments to the exercise price of certain outstanding vested and unvested option awards for eligible employees. The exercise price of eligible option awards was reduced to $38.78, which was the closing market price of our Class C capital stock on August 8, 2022. No other changes were made to the terms and conditions of the eligible option awards. In addition, the Board approved a supplemental grant of restricted stock units to eligible employees that was granted on August 8, 2022 and vests quarterly over a two-year period beginning in August 2022. The repricing of eligible option awards and the issuance of supplemental restricted stock units (collectively the “August 2022 Equity Award Actions”) has and is expected to continue to result in incremental share-based compensation expense over the remaining requisite service period, which is largely through the third quarter of 2024. For additional information regarding the August 2022 Equity Award Actions, see Note 16 in the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022.
Change in Reportable Segments
Beginning in 2023, our chief operating decision maker manages our business, makes operating decisions, and evaluates operating performance on the basis of the company as a whole, instead of on a segment basis as he did prior to 2023. Accordingly, this change resulted in revisions to the nature and substance of information regularly provided to and used by the chief operating decision maker. This serves to align our reported results with our ongoing growth of 6%.

We generatestrategy and our intent to provide integrated customer solutions for all tasks and services related to facilitating real estate transactions. As a result, we have determined that we have a single operating and reportable segment.

Revenue Overview
Our revenue is classified into four categories: Residential, Rentals, Mortgages and Other. Certain prior period amounts have been revised to reflect these changes.
Residential. Residential revenue includes revenue generated by our Premier Agent and new construction marketplaces, as well as revenue from the sale of advertising services and our suite of marketing software andbusiness technology solutions to businesses and professionals primarily associated with the residentialfor real estate mortgageprofessionals through StreetEasy for-sale product offerings and rental industries. These professionals include real estate, mortgage and rental professionals and brand advertisers. Our two primary revenue categories are marketplace revenue and display revenue.

Premier Agent revenue is generated by the sale of advertising under our Premier Agent and Premier Broker programs, which offer a suite ofservices, as well as marketing and business technology products and services, to help real estate agents and brokers grow and manage their businesses and brands.businesses.

Premier Agent products, which include the delivery of validated customer connections, or leads, are primarily offered on a share of voice basis.

Connections are delivered when customer contact information is provided to Premier Agent partners. Connections are provided as part of our suite of advertising services for Premier Agent partners; we do not charge a separate fee for these customer leads.
We also offer a pay for performance pricing model called “Flex” for Premier Agent advertising productservices in certain markets to select partners. With the Flex model, Premier Agent partners are provided with validated leads at no initial cost and our Premier Brokerpay a performance advertising productfee only when a real estate transaction is closed with one of the leads, generally within two years.

Financial Overview
For the three months ended September 30, 2017,2023 and 2022, we generated total revenue of $281.8$496 million as compared to $224.6and $483 million, in the three months ended September 30, 2016,respectively, an increase of 25%3%. ThisThe increase in total revenue was primarily attributable to the result of a $38.7following:
Rentals revenue increased by $25 million or 24%, increase in Premier Agent revenue, and a $16.0 million, or 55%, increase in other real estate revenue. There were approximately 175.2 million average monthly unique users of our mobile applications and websites for the three months ended September 30, 2017, representing year-over-year growth of 6%. Visits increased 19% to 1,667.1$99 million for the three months ended September 30, 2017 from 1,403.82023 compared to $74 million for the three months ended September 30, 2016.

In September 2017, we acquired New Home Feed. New Home Feed is2022. The increase in Rentals revenue was primarily due to a leading provider of listing management and syndication tools20% increase in quarterly revenue per average monthly rentals unique visitor to $3.30 for the new construction industry. For additional information about the acquisition of New Home Feed, see Note 6 to our condensed consolidated financial statements.

As ofthree months ended September 30, 2017, we had 3,060 full-time employees2023 as compared to 2,776 full-time employees$2.74 for the three months ended September 30, 2022, primarily driven by lower occupancy rates and the corresponding increase in advertising spend from multifamily property managers as well as growth in multifamily property listings. The increase in Rentals revenue was also driven by growth in average monthly rentals unique visitors which increased 11% to 30 million during the three months ended September 30, 2023 from 27 million during the three months ended September 30, 2022.

Residential revenue decreased by $10 million to $362 million for the three months ended September 30, 2023 compared to $372 million for the three months ended September 30, 2022. The decrease in Residential revenue was primarily driven by a 5% decrease in the number of December 31, 2016.

visits for the three months ended September 30, 2023 compared to the three months ended September 30, 2022, due to macro housing market factors including low housing inventory, fewer new for-sale listings, increases and volatility in mortgage interest rates, as well as home price fluctuations. The impact of the decrease in visits was partially offset by a 3% increase in Residential revenue per visit, driven by continued improvement in our ability to connect high-intent customers to agents.

Mortgages revenue decreased by $2 million to $24 million for the three months ended September 30, 2023 compared to $26 million for the three months ended September 30, 2022, driven by an $8 million decrease in revenue from Custom Quote and Connect advertising services due to a decrease in demand for mortgages attributable to the higher interest rate environment as compared to the prior year period. This resulted in a 40% decrease in leads generated from marketing products sold to mortgage professionals. The decrease in revenue from Custom Quote and Connect advertising services was offset by an $8 million increase in mortgage originations revenue, as total loan origination volume increased 69%, primarily driven by continued growth in Zillow Home Loans purchase loan originations.
During the three months ended September 30, 2023 and 2022, we generated gross profit of $386 million and $394 million, respectively, a decrease of 2%.
Key Metrics

Management has identified visits, unique users and visitsthe volume of loans originated through Zillow Home Loans as relevant to investors’ and others’ assessment of our financial condition and results of operations.

Visits
The number of visits is an important metric because it is an indicator of consumers’ level of engagement with our mobile applications, websites and other services. We believe highly engaged consumers are more likely to use our products and services, including Zillow Homes Loans, or be transaction-ready real estate market participants and therefore are more sought-after by our Premier Agent partners.

We define a visit as a group of interactions by users with the Zillow, Trulia and StreetEasy mobile applications and websites. A single visit can contain multiple page views and actions, and a single user can open multiple visits across domains, web browsers, desktop or mobile devices. Visits can occur on the same day, or over several days, weeks or months.
Zillow and StreetEasy measure visits with Google Analytics, and Trulia measures visits with Adobe Analytics. Visits to Trulia end after thirty minutes of user inactivity. Visits to Zillow and StreetEasy end either: (i) after thirty minutes of user inactivity or at midnight; or (ii) through a campaign change. A visit ends through a campaign change if a visitor arrives via one campaign or source (for example, via a search engine or referring link on a third-party website), leaves the mobile application or website, and then returns via another campaign or source.

During the three and nine month periods ended September 30, 2023, visits to our mobile applications and websites decreased by 5% and 6%, respectively, compared to the three and nine month periods ended September 30, 2022. These decreases were primarily driven by macro housing market factors including low housing inventory, fewer new for-sale listings, increases and volatility in mortgage interest rates as well as home price fluctuations.
Unique Users

Measuring unique users is important to us because much of our marketplace revenue depends in part on our ability to enableconnect home buyers and sellers, renters and individuals with or looking for a mortgage to real estate, rental and mortgage professionals, to connect with our users,products and our display revenue depends in part on the number of impressions delivered to our users.services. Growth in consumer traffic to our mobile applications and websites increases the number of impressions, clicks, connections, leads and clicksother events we can monetize to generate revenue. For example, our revenue depends in part on users accessing our marketplacemobile applications and display revenue categories. In addition, our communitywebsites to engage in the sale, purchase and financing of users improves the qualityhomes, including with Zillow Home Loans, and a significant portion of our living databaseResidential revenue, Rentals revenue and Other revenue depend on advertisements being served to users of homes with their contributions, which in turn attracts more users.

our mobile applications and websites.

We count a unique user the first time an individual accesses one of our mobile applications using a mobile device during a calendar month and the first time an individual accesses one of our websites using a web browser during a calendar month. If an individual accesses our mobile applications using different mobile devices within a given month, the first instance of access by each such mobile device is counted as a separate unique user. If an individual accesses more than one of our mobile applications within a given month, the first access to each mobile application is counted as a separate unique user. If an individual accesses our websites using different web browsers within a given month, the first access by each such web browser is counted as a separate unique user. If an individual accesses more than one of our websites in a single month, the first access to each website is counted as a separate unique user since unique users are tracked separately for each domain. Zillow, StreetEasy HotPads, Naked Apartments and RealEstate.com (as of June 2017)HotPads measure unique users with Google Analytics, and Trulia measures unique users with Adobe Analytics.
Due to third-party technological limitations, user software settings or user behavior, Google Analytics (formerly called Omniture analytical tools).

Basis of Presentation

Revenue

We generate revenue from the sale of advertising services and our suite of marketing software and technology solutions to businesses and professionals primarily associated with the residential real estate, mortgage and rental industries. These professionals include real estate, mortgage and rental professionals and brand advertisers. Our two primary revenue categories are marketplace revenue and display revenue.

Marketplace Revenue.Marketplace revenue for the three and nine month periods ended September 30, 2017 and 2016 consisted of Premier Agent revenue, other real estate revenue and mortgages revenue.

Premier Agent revenue is derived from our Premier Agent and Premier Broker programs. Our Premier Agent and Premier Broker programs offer a suite of marketing and business technology products and services to help real estate agents and brokers achieve their advertising needs, while growing and managing their businesses and brands. All Premier Agents and Premier Brokers receive access to a dashboard portal on our website that provides individualized program performance analytics, self-service ad buying tools and our free customer relationship management, or CRM, tool that captures detailed information about each contact made with a Premier Agent or Premier Broker through our mobile and web platforms.

We offer our flagship Premier Agent advertising product and our Premier Broker advertising product on a cost per impression basis. Impressions are delivered when a sold advertisement appears on pages viewed by users of our mobile applications and websites. From 2012 through the end of the third quarter of 2016, we had primarily charged customers for our Premier Agent product based on the number of impressions delivered on our buyer’s agent list in zip codes purchased and a contracted maximum cost per impression. Our Premier Agent and Premier Broker products include multiple deliverables which are accounted for as a single unit of accounting, as the delivery or performance of the undelivered elements is based on trafficindividual to our mobile applications and websites. With this pricing method, we recognized revenue related to our impression-based Premier Agent and Premier Broker products basedIn such instances, Google Analytics would count different instances of access by the same individual as separate unique users. Accordingly, reliance on the lessernumber of (i)unique users counted by Google Analytics may overstate the actual number of impressions delivered on our buyer’s agent list during the period multiplied by the contracted maximum cost per impression, or (ii) the contractual maximum spend on a straight-line basis during the contractual period over which the services are delivered, typically over a period of six months or twelve months and then month-to-month thereafter.

In 2016, we began testing and implementation of a new auction-based pricing method for our Premier Agent product by which we determine the cost per impression delivered in each zip code based upon the total amount spent by Premier Agents to purchase impressions in the zip code during the month. The cost per impression that we charge is dynamic – as demand for impressions in a zip code increases or decreases, the cost per impression in that zip code may be increased or decreased. This new auction-based pricing method complements our self-serve account interface, which we introduced to Premier Agents over the course of 2016. The interface includes account management tools that allow agent advertisers to independently control their budgets, impression buys, and the duration of their advertising commitment. We began testing this auction-based pricing method for our Premier Agent product to better align our revenue opportunities with increasing traffic levels to our mobile and web platforms and leveraging increasing demand by real estate agents forunique users who access to home shoppers who use our mobile applications and websites. In the fourth quarter of 2016, we implemented this method broadly for all existing and new agent advertisers, including brokerages and other teams. With this auction-based pricing method, we recognize revenue related to our dynamic impression-based Premier Agent and Premier Broker products based on the contractual maximum spend on a straight-line basis during the contractual period over which the services are delivered. In our history of building our real estate and other information marketplaces and product offerings, we have continually evaluated and utilized various pricing and value delivery strategies in order to better align our revenue opportunities with the growth in usage of our mobile and web platforms.

We continue to support some legacy Trulia Premier Agent products, which are primarily sold on a fixed fee subscription basis for periods that generally range from six months to 12 months. Subscription advertising revenue for Trulia’s products included in Premier Agent revenue is recognized on a straight-line basis during the contractual period over which the services are delivered.

Other real estate revenue primarily includes revenue generated by Zillow Group Rentals, as well as revenue from the sale of various other marketing and business products and services to real estate professionals, including our new construction marketing solutions. Zillow Group Rentals includes our rentals marketplace and suite of tools for rental professionals. Rentals revenue primarily includes revenue generated by advertising sold to property managers and other rental professionals on a cost per lead, cost per lease and cost per click generated basis whereby we recognize revenue as leads are delivered to rental professionals or as qualified leases are confirmed. Our new construction marketing solutions allow homebuilders to showcase their available inventory to home shoppers. New construction revenue primarily includes revenue generated by advertising sold to builders on a cost per residential community basis whereby revenue is recognized based on the contractual spend on a straight-line basis during the contractual period over which the services are delivered.

Mortgages revenue primarily includes marketing products sold to mortgage professionals on a cost per lead basis, including our Long Form and Custom Quote services. Mortgages revenue also includes revenue generated by Mortech, which provides subscription-based mortgage software solutions, including a product and pricing engine and lead management platform, for which we recognize revenue on a straight-line basis during the contractual period over which the services are delivered. For our Long Form and Custom Quote cost per lead mortgage marketing products, generally, participating qualified mortgage professionals make a prepayment to gain access to consumers interested in connecting with mortgage professionals. Through Long Form, consumers answer a series of

questions to find a local lender, and mortgage professionals receive consumer contact information. Consumers who request rates for mortgage loans in Custom Quotes are presented with customized quotes from participating mortgage professionals. We only charge mortgage professionals a fee when users contact mortgage professionals through Long Form or Custom Quotes. Mortgage professionals who exhaust their initial prepayment can then prepay additional funds to continue to participate in the marketplace. We recognize revenue when a user contacts a mortgage professional through Zillow Group’s mortgages platform.

Display Revenue. Display revenue primarily consists of graphical mobile and web advertising sold on a cost per thousand impressions or cost-per-click basis to advertisers promoting their brands on our mobile applications and websites andduring the period.

During the three months ended September 30, 2023, total loan origination volume increased 69% compared to the three months ended September 30, 2022. This increase was primarily driven by the continued growth in Zillow Home Loans purchase loan originations, partially offset by a decrease in refinance loan origination volume, which was impacted by interest rate increases. During the nine months ended September 30, 2023, total loan origination volume decreased 19% compared to the nine months ended September 30, 2022. This decrease was primarily driven by a decrease in refinance loan origination volume which was impacted by interest rate increases, partially offset by the continued growth in Zillow Home Loans purchase loan originations.

Total revenue increased $13 million, or 3%, to $496 million:
Rentals revenue increased $25 million, or 34%. The increase in Rentals revenue was primarily due to a 20% increase in quarterly revenue per average monthly rentals unique visitor to $3.30 for the three months ended September 30, 2023 as compared to $2.74 for the three months ended September 30, 2022, primarily driven by lower occupancy rates and the corresponding increase in advertising spend from multifamily property managers as well as growth in multifamily property listings, which drove a percentage42% increase in multifamily rentals revenue. We calculate quarterly revenue per average monthly rentals unique visitor by dividing total Rentals revenue for the period by the average monthly rentals unique visitors for the period and then dividing by the number of quarters in the period. The increase in Rentals revenue was also driven by growth in average monthly rentals unique visitors which increased 11% to 30 million during the three months ended September 30, 2023 from 27 million during the three months ended September 30, 2022. Average monthly rentals unique visitors are measured with Comscore data, which includes average monthly unique visitors on rental listings on Zillow, Trulia and HotPads mobile apps and websites. We expect Rentals revenue to decrease in absolute dollars during the three months ending December 31, 2023, primarily due to the impact of seasonality on rental property listings and landlord advertising spend.
Residential revenue decreased $10 million, or 3%. The decrease in Residential revenue was primarily driven by a 5% decrease in the number of visits for the three months ended September 30, 2023 compared to the three months ended September 30, 2022 due to macro housing market factors including low housing inventory, fewer new for-sale listings, increases and volatility in mortgage interest rates as well as home price fluctuations. The impact of the decrease in visits was partially offset by a 3% increase in Residential revenue per visit to $0.138 for the three months ended September 30, 2023 from $0.134 for the three months ended September 30, 2022, primarily driven by continued improvement in our ability to connect high-intent customers to agents. We calculate Residential revenue per visit by dividing the revenue generated by our Residential offerings by the number of visits in the period. As a result of the housing market factors described above, Premier Agent revenue decreased 3% during the three months ended September 30, 2023 compared to the three months ended September 30, 2022. We expect Residential revenue to decrease in absolute dollars during the three months ending December 31, 2023, primarily due to continued pressure from the macro housing market factors described above and the impact of seasonality on real estate transaction volumes.

Mortgages revenue decreased $2 million, or 8%, driven by an $8 million decrease in our Custom Quote and Connect advertising services revenue, offset by an $8 million increase in mortgage originations revenue. The decrease in our Custom Quote and Connect advertising revenue was primarily due to a 40% decrease in leads generated from marketing products sold to mortgage professionals. This decrease in leads was driven by a decrease in demand for mortgages attributable to the higher interest rate environment as compared to the prior year period. The decrease in Custom Quote and Connect advertising services revenue was offset by an $8 million increase in mortgage originations revenue, as total revenue:

loan origination volume increased 69% from $271 million for the three months ended September 30, 2022 to $457 million for the three months ended September 30, 2023, primarily driven by continued growth in Zillow Home Loans purchase loan origination volume, partially offset by a decrease in refinance loan origination volume due to the impact of interest rate increases. The increase in mortgage originations revenue was also attributable to a 40% increase in gain on sale margin. Gain on sale margin represents the net gain on sale of mortgage loans divided by total loan origination volume for the period. Net gain on sale of mortgage loans includes all components related to the origination and sale of mortgage loans, including the net gain on sale of loans into the secondary market, loan origination fees, unrealized gains and losses associated with changes in fair value of interest rate lock commitments and mortgage loans held for sale, realized and unrealized gains or losses from derivative financial instruments and the provision for losses relating to representations and warranties.

Nine months ended September 30, 2023 compared to nine months ended September 30, 2022
Total revenue decreased $52 million, or 3%, to $1,471 million:
Residential revenue decreased $79 million, or 7%. This decrease was driven by a 6% decrease in the number of visits for the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022 due to macro housing market factors including low housing inventory, fewer new for-sale listings, increases and volatility in mortgage interest rates as well as home price fluctuations. These factors also resulted in an 8% decrease in Premier Agent revenue during the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022.
Mortgages revenue decreased $27 million, or 27%. This decrease was driven by a decline in our Custom Quote and Connect advertising services revenue. The decrease in our Custom Quote and Connect advertising revenue was primarily due to a 35% decrease in leads generated from marketing products sold to mortgage professionals. This decrease in leads was driven by a decrease in demand for mortgages attributable to the higher interest rate environment as compared to the prior year period.
Rentals revenue increased $58 million, or 28%. The increase in Rentals revenue was primarily due to growth in average monthly rentals unique visitors which increased 15% to 30 million during the nine months ended September 30, 2023 from 26 million during the nine months ended September 30, 2022. The increase in Rentals revenue was also driven by an 11% increase in quarterly revenue per average monthly rentals unique visitor to $2.93 for the nine months ended September 30, 2023 as compared to $2.64 for the nine months ended September 30, 2022, primarily driven by lower occupancy rates and the corresponding increase in advertising spend from multifamily property managers as well as growth in multifamily property listings.

To provide investors with additional information regarding our financial results, we have disclosed Adjusted EBITDA, a non-GAAP financial measure, within this Quarterly Report on Form 10-Q, a non-GAAP financial measure.10-Q. We have provided a reconciliation below of Adjusted EBITDA to net income (loss),loss, the most directly comparable GAAPU.S. generally accepted accounting principle (“GAAP”) financial measure.

We have included Adjusted EBITDA in this Quarterly Report on Form 10-Q becauseas it is a key metric used by our management and board of directorsBoard to measure operating performance and trends and to prepare and approve our annual budget. In particular, the exclusion of certain expenses in calculating Adjusted EBITDA facilitates operating performance comparisons on a period-to-period basis.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider itthis measure in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

Adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments;

Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

Adjusted EBITDA does not reflect the results of discontinued operations;
Adjusted EBITDA does not consider the potentially dilutive impact of share-based compensation;

Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements;expenditures or contractual commitments;

Adjusted EBITDA does not reflect impairment and restructuring costs;
Adjusted EBITDA does not reflect acquisition-related costs;

Adjusted EBITDA does not reflect the gain on divestiture of business;

Adjusted EBITDA does not reflect interest expense or other income;income, net;

Adjusted EBITDA does not reflect income taxes; and

Other companies, including companies in our own industry, may calculate Adjusted EBITDA differently thanfrom the way we do, limiting its usefulness as a comparative measure.

Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including various cash flowcash-flow metrics, net income (loss)loss and our other GAAP results.

Overall2022

Cost of revenue increased by $57.2$21 million, or 25%24%, primarily driven by increases of $15 million in depreciation and amortization expense due to an increase in website development costs, $3 million in ad serving costs and $3 million in software and hardware costs.
Nine months ended September 30, 2023 compared to nine months ended September 30, 2022
Cost of revenue increased $28 million, or 10%, primarily driven by increases of $22 million in depreciation and amortization expense due to an increase in website development costs, $6 million in ad serving costs, $6 million in software and hardware costs and $4 million in mortgage loan processing costs due to increased purchase loan origination volume. These increases were partially offset by a $7 million decrease in lead acquisition costs as we focus on organic growth of our mortgage origination business and a $2 million decrease in credit card processing fees attributable to the previously mentioned decrease in revenue.

Three months ended September 30, 2023 compared to three months ended September 30, 2022
General and administrative expenses decreased $7 million, or 5%, primarily due to a decrease of $10 million in headcount-related expenses, including share-based compensation expense, primarily driven by the recognition of incremental share-based compensation expense in the three months ended September 30, 20172022 in connection with the repricing of eligible option awards in connection with the August 2022 Equity Award Actions, partially offset by an increase of $2 million in third-party professional service fees.
Nine months ended September 30, 2023 compared to 164.5nine months ended September 30, 2022
General and administrative expenses increased $37 million, average monthly unique usersor 10%, primarily due to increases of $34 million in headcount-related expenses, including share-based compensation expense, primarily driven by an $18 million increase in share-based compensation expense associated with the departures of certain personnel, as well as the impact of the August 2022 Equity Award Actions. The increase in general and administrative expenses was also driven by increases of $3 million in third-party professional service fees and $3 million in software and hardware costs.
Impairment and Restructuring Costs
Impairment and restructuring costs were $1 million and $9 million for the three and nine month periods ended September 30, 2023, respectively. The nine months ended September 30, 2023 include impairment costs of $6 million related to reductions in our right of use assets associated with changes in the use of certain office space in our lease portfolio and employee termination costs of $3 million.
There were no impairment and restructuring costs incurred during the three months ended September 30, 2016, representing year-over-year growth of 6%. This increase in unique users increased the number of impressions2022. Impairment and clicks we monetized in our marketplace and display revenue categories. In connection with the hurricanes that occurred during the summer of 2017, we worked closely with our Premier Agents and other advertisers in affected areas to help manage their advertising budgets. We estimate that relief initiatives, which included billing credits and other forms of advertiser assistance, as well as lost sales, impacted Premier Agent revenue by more than $0.8restructuring costs totaled $14 million for the quarterly period ended September 30, 2017. We expect Premier Agent revenue for

the three months ended December 31, 2017 will be impacted by approximately $1.0 million due to relief initiatives. We also experienced a temporary decline in traffic to our mobile applications and websites from consumers in impacted areas during September 2017, which may have impacted the number of unique users and visits for the threenine months ended September 30, 2017,2022. These costs do not qualify as discontinued operations and may impactwere primarily attributable to employee termination costs associated with the numberwind down of unique usersZillow Offers operations. For additional information regarding these costs, see Note 3 of our Notes to Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

Other Income, net
Other income, net consists primarily of interest income earned on our cash, cash equivalents and visitsinvestments, and fair value adjustments on an outstanding warrant.
Other income, net increased $22 million and $89 million for the three and nine month periods ended September 30, 2023, respectively. The increase in other income, net was primarily driven by increases in returns on investments due to the higher interest rate environment as compared to the prior year period.
Income Taxes
We are primarily subject to income taxes in the United States (federal and state), as well as certain foreign jurisdictions. As of September 30, 2023 and December 31, 2022, we have provided a valuation allowance against our net deferred tax assets that we believe, based on the weight of available evidence, are not more likely than not to be realized. There is a reasonable possibility that within the next several years, sufficient positive evidence will become available to demonstrate that a significant portion of the valuation allowance against our U.S. net deferred tax assets will no longer be required. We have accumulated federal tax losses of approximately $1.8 billion as of December 31, 2022, which are available to reduce future taxable income. We have accumulated state tax losses of approximately $63 million (tax effected) as of December 31, 2022.
Income tax expense (benefit) for the three and nine months ended December 31, 2017.

Marketplace revenue grew to $262.7September 30, 2023 and the nine months ended September 30, 2022 was not material. We recorded income tax expense of $3 million for the three months ended September 30, 2017 from $206.9 million for the three months ended September 30, 2016, an increase of $55.8 million. Marketplace revenue represented 93% of total revenue for the three months ended September 30, 2017 compared to 92% of total revenue for the three months ended September 30, 2016. The increase in marketplace revenue was primarily attributable to the $38.7 million, or 24%, increase in Premier Agent revenue. Premier Agent revenue was positively impacted by an increase in visits. Visits increased 19% to 1,667.1 million for the three months ended September 30, 2017 from 1,403.8 million for the three months ended September 30, 2016. This increase in visits increased the number of impressions we could monetize in our Premier Agent marketplace. Premier Agent revenue per visit increased by 5% to $0.118 for the three months ended September 30, 2017 from $0.113 for the three months ended September 30, 2016. We calculate Premier Agent revenue per visit by dividing the revenue generated by our Premier Agent and Premier Broker programs in the period by the number of visits in the period. We believe Premier Agent revenue was also positively impacted by the full implementation of the new pricing method for our Premier Agent product, which may have increased the demand for our advertising platform. As discussed above, during the year ended December 31, 2016, we began meaningful testing and implementation of a new auction-based pricing method for our Premier Agent product, our flagship advertising product, by which we determine the cost per impression delivered in each zip code in a dynamic way based on demand for impressions in that zip code. We continue to evaluate this pricing method, and in the fourth quarter of 2016, we implemented this method broadly for all existing and new agent advertisers, including brokerages and other teams. We believe the increase in Premier Agent revenue was also due in part to increased advertising sales to current Premier Agents, including brokerages and other teams. Revenue generated from Premier Agent accounts which have advertised with Zillow Group for more than one year grew by 45% for the three months ended September 30, 2017 as compared to the three months ended September 30, 2016.

The increase in marketplace revenue was also attributable to growth in other real estate revenue, which increased by $16.0 million, or 55%, for the three months ended September 30, 2017 compared to the three months ended September 30, 2016. The increase in other real estate revenue was primarily a result of a 56% increase in revenue generated by Zillow Group Rentals. Growth in Zillow Group Rentals revenue was primarily attributable to increases in consumer adoption of our rentals information marketplaces, which in turn increased the likelihood of a lead, lease, or click that we monetize, and advertiser adoption of our cost per lead, cost per lease and cost per click advertising products, as well as enhancements to our marketing products that improve the ways in which consumers and advertisers connect through the Zillow Group Rentals marketplace. Other real estate revenue was also positively impacted by increased advertising sales to new home builders through our New Construction platform.

The increase in marketplace revenue was also attributable to growth in mortgages revenue, which increased by $1.1 million, or 6%, for the three months ended September 30, 2017 compared to the three months ended September 30, 2016. The increase in mortgages revenue was primarily a result of a 31% increase in our average revenue per loan information request for the three months ended September 30, 2017 compared to the three months ended September 30, 2016. The increase in average revenue per loan information request was primarily a result of our flagship mortgage advertising platform, Long Form, which yields higher revenue than our other mortgage advertising products, and increased consumer adoption of Long Form, which was driven by product enhancements that allow us to monetize our mortgages products more efficiently. There were approximately 5.5 million mortgage loan information requests submitted by consumers for the three months ended September 30, 2017 compared to 6.9 million mortgage loan information requests submitted by consumers for the three months ended September 30, 2016, a decrease of 20%. We believe the decrease in the number of loan information requests submitted by consumers is due to our strategic decision to improve loan information request quality by requiring consumers to provide more information before a loan information request is submitted. We believe our mortgage product feature change creates a better experience for consumers and more valuable loan information requests for our lender advertisers.

Display revenue was $19.1 million for the three months ended September 30, 2017 compared to $17.7 million for the three months ended September 30, 2016, an increase of $1.4 million. Display revenue represented 7% of total revenue for the three months ended September 30, 2017 compared to 8% of total revenue for the three months ended September 30, 2016. The increase in display revenue was primarily a result of the increase in unique users, which resulted in a greater number of impressions and clicks we monetized.

The increase in cost of revenue was primarily attributable to a $2.2 million increase in revenue share costs, a $1.4 million increase in data center and connectivity costs, a $0.4 million increase in headcount-related expenses, including share-based compensation expense, and a $0.5 million increase in various miscellaneous expenses. We expect our cost of revenue to increase in absolute dollars in future years as we continue to incur more expenses that are associated with growth in revenue.

The increase in sales and marketing expenses was primarily attributable to increased marketing and advertising expenses of $6.8 million,2022, primarily related to advertising spend during the peak residential real estate transaction period to attract consumers across online and offline channels, which supports our growth initiatives.

In addition to the increases in marketing and advertising, headcount-related expenses increased $5.0 million, including share-based compensation expense, due primarily to significant growth in the sizestate income taxes.

Approximately $13.2 million of the increase related to growth in headcount-related expenses, including share-based compensation expense, as we continue to grow our engineering teams to support current and future product initiatives. In addition, there was a $3.6 million increase in other non-capitalizable data content expense, a $1.4 million increase in the amortization of purchased data content intangible assets, and a $0.7 million increase in various miscellaneous expenses.

Amortization expense included in technology and development for capitalized website development costs and software was $11.2 million and $11.3 million, respectively, for the three months ended September 30, 2017 and 2016. Amortization expense included in technology and development related to intangible assets recorded in connection with acquisitions was $9.8 million and $9.6 million, respectively, for the three months ended September 30, 2017 and 2016.

Overall revenue increased by $175.5 million, or 28%, for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016. Marketplace revenue increased by 31%, and display revenue increased by 3%.

Marketplace revenue grew to $741.6 million for the nine months ended September 30, 2017 from $567.4 million for the nine months ended September 30, 2016, an increase of $174.2 million. Marketplace revenue represented 93% of total revenue for the nine months ended September 30, 2017 compared to 92% of total revenue for the nine months ended September 30, 2016. The increase in marketplace revenue was primarily attributable to the $122.1 million, or 28%, increase in Premier Agent revenue. Premier Agent revenue was positively impacted by an increase in visits. Visits increased 18% to 4,878.8 million for the nine months ended September 30, 2017 from 4,133.5 million for the nine months ended September 30, 2016. This increase in visits increased the number of impressions we could monetize in our Premier Agent marketplace. Premier Agent revenue per visit increased by 8% to $0.115 for the nine months ended September 30, 2017 from $0.106 for the nine months ended September 30, 2016. We believe Premier Agent revenue was also positively impacted by the full implementation of the new pricing method for our Premier Agent product, which may have increased the demand for our advertising platform. As discussed above, during the year ended December 31, 2016, we began meaningful testing and implementation of a new auction-based pricing method for our Premier Agent product, our flagship advertising product, by which we determine the cost per impression delivered in each zip code in a dynamic way based on demand for impressions in that zip code. We continue to evaluate this pricing method, and in the fourth quarter of 2016, we implemented this method broadly for all existing and new agent advertisers, including brokerages and other teams.

The increase in marketplace revenue was also attributable to growth in other real estate revenue, which increased by $44.6 million, or 61%, for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016. The increase in other real estate revenue was primarily a result of a 73% increase in revenue generated by Zillow Group Rentals. Growth in Zillow Group Rentals revenue was primarily attributable to increases in consumer adoption of our rentals information marketplaces, which in turn increased the likelihood of a lead, lease, or click that we monetize, and advertiser adoption of our cost per lead, cost per lease and cost per click advertising products, as well as enhancements to our marketing products that improve the ways in which consumers and advertisers connect through the Zillow Group Rentals marketplace.

The increase in marketplace revenue was also attributable to growth in mortgages revenue, which increased by $7.5 million, or 14%, for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016. The increase in mortgages revenue was primarily a result of a 62% increase in our average revenue per loan information request for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016. The increase in average revenue per loan

information request was primarily a result of our flagship mortgage advertising platform, Long Form, which yields higher revenue than our other mortgage advertising products, and increased consumer adoption of Long Form, which was driven by product enhancements that allow us to monetize our mortgages products more efficiently. There were approximately 17.3 million mortgage loan information requests submitted by consumers for the nine months ended September 30, 2017 compared to 24.8 million mortgage loan information requests submitted by consumers for the nine months ended September 30, 2016, a decrease of 30%.

We believe our mortgage product feature change creates a better experience for consumers and more valuable loan information requests for our lender advertisers.

Display revenue was $52.9 million for the nine months ended September 30, 2017 compared to $51.6 million for the nine months ended September 30, 2016, an increase of $1.3 million. Display revenue represented 6% of total revenue for the nine months ended September 30, 2017 compared to 8% of total revenue for the nine months ended September 30, 2016. The increase in display revenue was primarily a result of the increase in unique users, which resulted in a greater number of impressions and clicks we monetized.

In addition, there was a $30.4 million decrease in professional services fees, primarily as a result of our settlement of litigation with Move, as we incurred $28.8 million in legal costs related to our litigation with Move for the nine months ended September 30, 2016. These decreases were partially offset by a $5.7 million increase in estimated legal liabilities, a $5.6 million increase in building lease-related expenses including rent, utilities and insurance, a $4.5 million increase in headcount-related expenses, including share-based compensation expense, driven primarily by growth in headcount in shared corporate services to support our engineering and other teams, a $4.3 million increase in city and state taxes, a $4.1 million increase in bad debt expense, a $1.5 million increase in software and hardware costs, a $1.3 million increase in the loss on disposal of assets, and a $2.3 million increase in miscellaneous general and administrative expenses.

Liquidity and Capital Resources

Our primary sources of liquidity and capital resources are cash flows from operations, debt financing and equity offerings. Our cash requirements consist principally of working capital, general corporate needs and mortgage loan originations. We generally reinvest available cash flows from operations into our business and to service our debt obligations.
Sources of Liquidity
As of September 30, 20172023 and December 31, 2016,2022, we had cash and cash equivalents, investments and restricted cash of $3.3 billion and investments of $682.0 million and $507.5 million,$3.4 billion, respectively. Cash and cash equivalents balances consist of operating cash on deposit with financial institutions and money market funds and certificates of deposit with original maturities of three months or less.funds. Investments as of September 30, 2017 and December 31, 2016 consistedconsist of fixed income securities, which include U.S. government treasury securities, U.S. government agency securities, investment grade corporate notessecurities, and bonds, municipal securities, foreign government securities, commercial paper and certificatespaper. Restricted cash primarily consists of deposit.amounts held in escrow related to funding customer home purchases in our mortgage origination business. Amounts on deposit with third-party financial institutions exceed the Federal Deposit Insurance Corporation (“FDIC”) and the Securities Investor Protection Corporation insurance limits, as applicable. As of September 30, 2023, Zillow Group and its subsidiaries were in compliance with all debt covenants specified in the facilities described below.
We believe that cash from operations and cash and cash equivalents and investment balances will be sufficient to meet our ongoing operating activities, working capital, capital expenditures, strategic acquisitions and investments and other capital requirements for at least the next 12 months.

On February 17, 2015, We believe we acquired Trulia in a stock-for-stock transaction. The total purchase price of Trulia was approximately $2.0 billion. Our February 2015 acquisition of Trulia had a significant impact on our liquidity, financial positionwill meet longer-term expected future cash requirements and results of operations.

Further, as a result of the acquisition, Zillow Group entered into a supplemental indenture in respect of the 2020 Notes in the aggregate principal amount of $230.0 million, which supplemental indenture provides, among other things, that, at the effective time of the Trulia acquisition, (i) each outstanding 2020 Note is no longer convertible into shares of Trulia common stock and is convertible solely into shares of Zillow Group Class A common stock, pursuant to, and in accordance with, the terms of the indenture governing the 2020 Notes, and (ii) Zillow Group guaranteed all of the obligations of Trulia under the 2020 Notes and related indenture. The aggregate principal amount of the 2020 Notes is due on December 15, 2020 if not earlier converted or redeemed. Interest is payable on the 2020 Notes at the rate of 2.75% semi-annually on June 15 and December 15 of each year. In December 2016, the Company used approximately $370.2 million of the net proceeds from the issuance of the 2021 Notes discussed below to repurchase $219.9 million aggregate principal of the 2020 Notes in privately negotiated transactions.

Holders of the 2020 Notes may convert all or any portion of their notes, in multiples of $1,000 principal amount, at their option at any time prior to the close of business on the business day immediately preceding the maturity date. In connection with the supplemental indenture in respect of the 2020 Notes, the conversion ratio immediately prior to the effective time of the Trulia Merger of 27.8303 shares of Trulia common stock per $1,000 principal amount of notes was adjusted to 12.3567 shares of our Class A common stock per $1,000 principal amount of notes based on the exchange ratio of 0.444 per the Merger Agreement. This was equivalent to an initial conversion price of approximately $80.93 per share of our Class A common stock. In connection with the August 2015 distribution of shares of our Class C capital stock as a dividend to our Class A and Class B common shareholders, the conversion ratio has been further adjusted to 41.4550 shares of Class A common stock per $1,000 principal amount of notes, which is equivalent to a conversion price of approximately $24.12 per share of our Class A common stock. The conversion ratio will be adjusted for certain dilutive events and will be increased in the case of corporate events that constitute a “Make-Whole Fundamental Change” (as defined in the indenture governing the notes). The conversion option of the 2020 Notes has no cash settlement provisions. The conversion option does not meet the criteria for separate accounting as a derivative as it is indexed to our own stock.

The 2020 Notes are redeemable, at our option, in whole or in part on or after December 20, 2018, if the last reported sale price per share of our Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period.

For additional information regarding the 2020 Notes, see Note 9 to our condensed consolidated financial statements.

In December 2016, Zillow Group issued $460.0 million aggregate principal amount of 2021 Notes, which amount includes the exercise in full of the $60.0 million over-allotment option, to Citigroup Global Markets Inc. as the initial purchaser of the 2021 Notes in a private offering to the initial purchaser in reliance on the exemption from the registration requirements provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”) for resale to qualified institutional buyers as defined in, and pursuant to, Rule 144A under the Securities Act. The 2021 Notes bear interest at a fixed rate of 2.00% per year, payable semiannually in arrears on June 1 and December 1 of each year, beginning on June 1, 2017. The 2021 Notes are convertible into cash, shares of our Class C capital stock or a combination thereof, at the Company’s election. The 2021 Notes will mature on December 1, 2021, unless earlier repurchased, redeemed, or converted in accordance with their terms. The Company incurred transaction costs of approximately $12.2 million related to the issuance of the 2021 Notes, including approximately $11.5 million in fees to the initial purchaser, which amount was paid out of the gross proceeds from the note offering.

The net proceeds from the issuance of the 2021 Notes were approximately $447.8 million, after deducting fees and expenses. The Company used approximately $370.2 million of the net proceeds from the issuance of the 2021 Notes to repurchase a portion of the outstanding 2020 Notes in privately negotiated transactions. In addition, the Company used approximately $36.6 million of the net proceeds from the issuance of the 2021 Notes to pay the cost of Capped Call Confirmations as discussed in Note 9 to our condensed consolidated financial statements. The Company used the remainder of the net proceeds for general corporate purposes.

Prior to the close of business on the business day immediately preceding September 1, 2021, the 2021 Notes are convertible at the option of the holders of the 2021 Notes only under certain conditions, none of which conditions have been satisfied as of September 30, 2017. On or after September 1, 2021, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the 2021 Notes may convert their 2021 Notes at their option at the conversion rate then in effect, irrespective of these conditions. The Company will settle conversions of the 2021 Notes by paying or delivering, as the case may be, cash, shares of Class C capital stock, orthrough a combination of cash flows from operations, debt financing and sharesequity offerings, as applicable.

Capital Resources
We continue to invest in the development and expansion of our operations. Ongoing investments include, but are not limited to, improvements in our technology platforms, infrastructure and continued investments in sales and marketing. To finance these investments and ongoing operations, and in the event that we require additional funding to support strategic business opportunities, we have issued convertible senior notes. As of September 30, 2023, we have $1.7 billion aggregate principal of convertible senior notes outstanding. The convertible notes are senior unsecured obligations, and interest on the convertible notes is paid semi-annually. The following table summarizes our convertible senior notes as of the periods presented (in millions, except interest rates):

We may from time to time seek to redeem, retire or purchase outstanding debt through cash purchases and/or exchanges for cash, shares of stock or a combination of cash and stock, pursuant to the redemption terms of such debt securities, in open market purchases, privately negotiated transactions or otherwise. In particular, the 2024 Notes and 2026 Notes may be redeemed if the last reported sale price of our Class C capital stock exceeds $56.56 per share for a specified period of trading days. To the extent our Class C capital stock price rises above those levels, we may redeem the 2024 Notes and/or 2026 Notes, in which case, we would expect to settle any conversions in cash up to the principal amount and shares of Class C capital stock for any conversion obligation in excess of the principal amount. Such redemptions, repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved in any such transactions, individually or in the aggregate, may be material. Refer to Note 9 of our Notes to Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q for additional information regarding our convertible senior notes, including conversion rates, conversion and redemption dates and the related capped call transactions.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosures. We evaluate our estimates, judgments and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates, and the health of the real estate market and the broader economy have introduced significant additional uncertainty with respect to estimates, judgments and assumptions, which may materially impact our estimates. For information on our critical accounting policies and estimates, see Part II Item 7 (Management’s Discussion and Analysis of Financial Condition and Results of Operations) of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.2022. There have been no material changes to our critical accounting policies and estimates as previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risks in the ordinary course of our business. These risks primarily consist of fluctuations in interest rates.

Interest Rate Risk

Under our current investment policy, we invest our excess cash in money market funds, certificates of deposit,U.S. government treasury securities, U.S. government agency securities, foreign government securities, municipalinvestment grade corporate securities and corporate notes and bonds.commercial paper. Our current investment policy seeks first to preserve principal,capital, second to provide sufficient liquidity for our operating and capital needs and third to maximize yield without putting our principal at risk.

Our short-term investments are exposed to market risk due to the fluctuation of prevailing interest rates that may reduce the yield on our investments or their fair value. AsFor our investment portfolio, is short-term in nature, we do not believe an immediate 10% increase in interest rates would have a material effect on the fair market value of our portfolio.

As of September 30, 2017,2023, we have outstanding $460.0 millionhad approximately $1.7 billion aggregate principal Convertible Senior Notes due in 2021 (the “2021 Notes”). The 2021 Notes were issued in December 2016 and carry a fixed interest rateamount of 2.00% per year. As ofconvertible senior notes outstanding with maturities ranging from September 30, 2017, we also have2024 through September 2026. All outstanding $10.1 million aggregate principal Convertible Senior Notes due in 2020 (the “2020 Notes”). The 2020 Notes were guaranteed by Zillow Group in connection with our February 2015 acquisition of Trulia, Inc. The 2020 Notes carry a fixed interest rate of 2.75% per year. Since the 2020 Notes and 2021 Notesconvertible senior notes bear interest at fixed rates we have no directof interest and, therefore, do not expose us to financial statement risk associated with changes in interest rates. However, theThe fair values of the 2020 Notes and 2021 Notesconvertible senior notes change primarily when the market price of our stock fluctuates or interest rates change.

For these reasons, we do not expect

We are also subject to market risk which may impact our mortgage loan origination volume and associated revenue and the net interest margin derived from borrowings under our warehouse line of credit and master repurchase agreements that provide capital for Zillow Home Loans. Market risk occurs in periods where changes in short-term interest rates result in mortgage loans being originated with terms that provide a smaller interest rate spread above the financing terms of our warehouse line of credit and master repurchase agreements, which can negatively impact our results of operationsoperations. This risk is primarily mitigated through the expedited sale of our loans. As of September 30, 2023 and December 31, 2022, we had $91 million and $37 million, respectively, of outstanding borrowings on our warehouse line of credit and master repurchase agreements which bear interest either at a floating rate based on Secured Overnight Financing Rate (“SOFR”) plus an applicable margin, as defined by the governing agreements, or cash flows would be materially affectedBloomberg Short-Term Bank Yield Index Rate (“BSBY”) plus an applicable margin, as defined by a suddenthe governing agreements. We manage the interest rate risk associated with our mortgage loan origination services through the use of forward sales of mortgage-backed securities. Assuming no change in market interest rates.

Inflation Risk

We dothe outstanding borrowings on the warehouse line of credit and master repurchase agreements, we estimate that a one percentage point increase in SOFR or BSBY, as applicable, would not believe that inflation has hadhave a material effect on our annual interest expense associated with the warehouse line of credit and master repurchase agreements as of September 30, 2023 and December 31, 2022.

For additional details related to our credit facilities and convertible senior notes, see Note 9 to our Notes to Condensed Consolidated Financial Statements of this Quarterly Report on Form 10-Q.
Inflation Risk
The macroeconomic environment in the United States has experienced, and continues to experience inflationary pressures. While it is difficult to accurately measure the impact of these inflationary pressures on our business, resultswe believe these effects have been pervasive throughout our business during the past several quarters. In response to ongoing inflationary pressures in the United States, the Federal Reserve has implemented a number of operations or financial condition. increases to the federal funds rate in recent quarters. These increases have impacted other market rates derived from this benchmark rate, including mortgage interest rates. The increase in mortgage interest rates across the industry has decreased demand for mortgages overall and, in turn, had an adverse impact on our Mortgages revenue.
If inflationary pressures persist, our costs, were to become subject to significant inflationary pressures,in particular labor, marketing and hosting costs, may increase and we may not be able to fully offset such higher costs through price increases. In addition, uncertain or changing economic and market conditions, including inflation or deflation, may continue to affect demand for our products and services and the housing markets in which we operate. Our inability or failure to do soquickly respond to inflation could harm our business, results of operations and financial condition.

We cannot predict the duration or magnitude of these inflationary pressures, or how they may change over time, but we expect to see continued impacts on the residential real estate industry, our customers and our company. Despite these near-term effects, we do not expect these inflationary pressures to have a material impact on our ability to execute our long-term business strategy.

Foreign Currency Exchange Risk

We do not believe that foreign currency exchange risk has had a material effect on our business, results of operations or financial condition. As we do not maintain a significant balance of foreign currency, we do not believe an immediate 10% increase or decrease in foreign currency exchange rates relative to the U.S. dollar would have a material effect on our business, results of operations or financial condition.

Changes in Internal Control Over Financial Reporting

We implemented this new ERP system to enhance our overall system of internal control over financial reporting through further automation and integration of business processes. The ERP system was not implemented in response to any identified deficiency or material weakness in the Company’s internal control over financial reporting. As a result of this implementation, we have modified the design and documentation of certain internal control processes and procedures relating to the ERP system.
