Description of Business and Summary of Significant Accounting Policies

Description of Business—Redfin Corporation (“Redfin” or the “Company”) was incorporated in October 2002 and is headquartered in Seattle, Washington. The Company operates an online real estate marketplace and provides real estate services, including assisting individuals in the purchase or sale of their residential property. The Company also provides title and settlement services, originates and sells mortgages, and buys and sells residential properties via wholly-owned subsidiaries. The Company has operations located in multiple states nationwide.

Initial Public Offering—On August 2, 2017, the Company completed an initial public offering (the "IPO") whereby 10,615,650 shares of common stock were sold at a price of $15.00 per share, which included 1,384,650 shares pursuant to the underwriters' option to purchase additional shares. The Company received net proceeds of $144,380 after deducting the underwriting discount and offering expenses directly attributable to the IPO. Upon the closing of the IPO, all shares of the outstanding redeemable convertible preferred stock automatically converted into 55,422,002 shares of common stock on a one-for-one basis.

Initial Public Offering Costs—Costs, including legal, accounting and other fees and costs relating to the IPO were accounted for as a reduction in additional paid-in capital. Aggregate offering expenses totaled $3,708.

Basis of Presentation—The consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). The Company had no components of other comprehensive income (loss) during any of the periods presented, as such, a consolidated statement of comprehensive income (loss) is not presented. All amounts are presented in thousands, except share and per share data.

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 the Company's financial position as of June 30, 2018, the Company's results of operations for the three months and six months ended June 30, 2018 and 2017, and the Company's cash flows for the six months ended June 30, 2018 and 2017. The results for the three and six months ended June 30, 2018 are not necessarily indicative of the results to be expected for the year ending December 31, 2018 or for any interim period or for any other future year.

Principles of Consolidation—The unaudited condensed consolidated interim financial statements include the accounts of Redfin and its wholly owned subsidiaries. Intercompany transactions and balances have been eliminated.

Certain Significant Risks and Business Uncertainties—The Company is subject to the risks and challenges associated with companies at a similar stage of development. These include dependence on key individuals, successful development and marketing of its offerings, and competition with larger companies with greater financial, technical, and marketing resources. Further, to achieve substantially higher revenue in order to become profitable, the Company may require additional funds that may not be available or may not be on terms that are acceptable to the Company.

The Company operates in the online real estate marketplace and, accordingly, can be affected by a variety of factors. For example, management of the Company believes that any of the following factors could have a significant negative effect on the Company’s future financial position, results of operations, and cash flows: unanticipated fluctuations in operating results due to seasonality and cyclicality in the real estate industry, changes in home sale prices and transaction volumes, the Company’s ability to increase market share, competition and U.S. economic conditions. Since inception through June 30, 2018, the Company has incurred losses from operations and accumulated a deficit of $162,235, and has been dependent on equity financing to fund operations.

Use of Estimates—The preparation of consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and results of operations during the respective periods. The Company’s more significant estimates include, but are not limited to, valuation of deferred income taxes, stock-based compensation, prior to its conversion on August 2, 2017 the fair value of common stock and redeemable convertible preferred stock, capitalization of website development costs, recoverability of intangible assets with finite lives, and the fair value of reporting units for purposes of evaluating goodwill for impairment. The amounts ultimately realized from the affected assets or ultimately recognized as liabilities will depend on, among other factors, general business conditions and could differ materially in the near term from the carrying amounts reflected in the consolidated financial statements.

Significant Accounting Policies—There have been no material changes to the Company's significant accounting policies and estimates during the six months ended June 30, 2018, from the significant accounting policies included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2017, except as noted below.

Recently Adopted Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board ("FASB") issued a new Accounting Standard Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). This guidance provides 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 Company adopted ASU 2014-09 and its related amendments (collectively known as ASC 606) effective on January 1, 2018, using the modified retrospective adoption methodology. Real estate services, properties and other revenue contain single performance obligations and the Company believes the timing of the satisfaction of the performance obligations, triggering the recognition of revenue, did not differ from the Company's timing for recognizing revenue prior to adopting this pronouncement. Further description of the impact of this pronouncement is included in Note 2: Revenue from Contracts with Customers.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230). This guidance impacts the classification of certain cash receipts and cash payments in the statement of cash flows. The new standard made eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. The Company adopted the new standard on a retrospective basis on January 1, 2018. The adoption of this standard had no impact on the Company’s statement of cash flows.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This guidance impacts the classification and presentation of changes in restricted cash on the statement of cash flows. This guidance is effective 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. The Company early adopted this guidance on October 1, 2017. Upon adoption, the following balances were reclassified: restricted cash to the reconciliation of change in cash, cash equivalents and restricted cash, and other payables related to cash held in escrow on behalf of customers to financing activities. In the Company’s capacity as fiduciary, the cash receipt is a function of providing the customer with a service (title). Therefore, the escrow funds payable are akin to a repayment of debt, a financing activity, whereby the Company in its role as fiduciary is temporarily holding cash in its restricted accounts on behalf of its customers and subsequently releases the cash to settle the customers' contractual obligation. This reclassification will maintain an accurate reflection of the Company's cash flows from operating activities. The reconciliation of amounts previously reported to the revised amounts upon adoption are as follows:



Six Months Ended June 30, 2017	Previously reported			Adjustments			As revised

Operating activities	$	(371	)	$	218		$	(153	)
Financing activities	$	(261	)	$	7,814		$	7,553
Net change in cash, cash equivalents, and restricted cash⁽¹⁾	$	(9,820	)	$	(8,032	)	$	(1,788	)
⁽¹⁾Previously titled: net change in cash and cash equivalents

Recently Issued Accounting Pronouncements—In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This standard requires the recognition of a right-of-use asset and lease liability on the balance sheet for all leases. This standard 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 beginning of the earliest comparative period presented in the financial statements, and early adoption is permitted. The Company expects to adopt this guidance on January 1, 2019. Although the Company is in the process of evaluating the impact of adoption of the ASU on its consolidated financial statements, the Company currently believes the adoption of this guidance will be significant and the changes will be related to the recognition of new right-of-use assets and lease liabilities on the Company's balance sheet for leased facilities.

In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842). This guidance provides an additional (and optional) transition method whereby the new lease standard is applied at the adoption date and recognized as an adjustment to retained earnings. In addition, this ASU provides a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease and instead account for the lease as a single component if both the timing and pattern of transfer of the nonlease component(s) are the same, and if the lease would be classified as an operating lease. These amendments have the same effective date as ASU 2016-02.
