The Company generally places its cash and cash equivalents and short-term investments with high-credit-quality counterparties to make sure the financial institutions are stable when the Company’s deposits exceed Federal Deposit Insurance Corporation limits, and by policy, limit the amount of credit exposure to any one counterparty based on the Company’s analysis of the counterparty’s relative credit standing. The Company maintains its cash accounts with financial institutions where, at times, deposits exceed federal insurance limits.</font></div><div style="line-height:120%;padding-top:1px;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div></div>

The Company’s key revenue components are brokerage revenue, partner revenue, and other revenue. The Company recognizes commission-based brokerage revenue upon closing of a real estate transaction, net of any commission refund or any closing-cost reduction. Partner revenue consists of fees earned by referring customers to partner agents. Partner revenue is earned and recognized when partner agents close a referred transaction, net of any refund provided to customers. Fees and revenue from other services are recognized when the service is provided. Revenue earned from selling homes previously purchased by Redfin Now is recorded at closing on a gross basis, representing the sales price of the home. </font></div><div style="line-height:120%;padding-top:1px;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:125%;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;color:#231f20;">Revenue earned but not received is recorded as accrued revenue on the accompanying consolidated balance sheets, net of an allowance for doubtful accounts.
