We adopted this update effective January 1, 2018, </span></div><div style="line-height:120%;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">using the modified retrospective approach. The principle of this update requires an entity to recognize revenue representing the transfer of services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those services, recognized as the performance obligations are satisfied.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">This update is primarily applicable to revenues from our Services segment. This update did not change revenue recognition principles related to our investments and insurance products, which together represented the majority of our total revenue for 2018 and are subject to other GAAP guidance discussed elsewhere within our disclosures.

Although some of our contracts and assignments are recurring in nature, and include repetitive monthly assignments, a portion of our engagements are transactional in nature. Due to the transactional nature of our business, our Services segment revenues may fluctuate from period to period as transactions are commenced or completed. We do not recognize revenue or expense related to amounts advanced by us and subsequently reimbursed by clients for maintenance or repairs, because we do not take control of the service prior to the client taking control. We record an expense if an advance is made by us that is not in accordance with a client contract, and the client is not obligated to reimburse us.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Due to the nature of the services provided, our Services arrangements with customers may include fixed price contracts, and to a lesser extent, percentage-of-sale contracts.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Fixed-Price Contracts.</span><span style="font-family:inherit;font-size:10pt;"> Following the Clayton sale, we use fixed-price contracts in our real estate valuation and asset management business activities, our title and closing services, as well as our services related to single family rental services and contract underwriting. Prior to the Clayton sale, we also used fixed-price contracts in our surveillance business for our servicer oversight services and RMBS surveillance services. Under fixed-price contracts we agree to perform the specified services and deliverables for a pre-determined per-unit or per-file price or day rate. Each service qualifies as a separate performance obligation and revenue is recognized as the service performed is made available to the client.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Percentage-of-Sale Contracts. </span><span style="font-family:inherit;font-size:10pt;">Under percentage-of-sale contracts, we are paid a contractual percentage of the sale proceeds upon the sale of each property. These contracts are only used for a portion of our REO management services and our real estate brokerage services. In addition, through the use of our proprietary technology, property leads are sent to select clients. Revenue attributable to services provided under a percentage-of-sale contract is recognized over time and measured based on the progress to date and typically coincides with the client’s successful closing on the property. The revenue recognized for these transactions is based on a percentage of the sale.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In certain instances, fees are received at the time that an asset is assigned to Radian for management. These fees are recorded as deferred revenue and are recognized over time based on progress to date and the availability to customers.</span></div>

This ASU and the associated subsequent amendments require that financial assets measured at their amortized cost basis be presented at the net amount expected to be collected. Credit losses relating to our available-for-sale debt securities are to be recorded through an allowance for credit losses, rather than a write-down of the asset, with the amount of the allowance limited to the amount by which fair value is less than amortized cost. This allowance method will allow reversals of credit losses if the estimate of credit losses declines. This ASU will also affect certain of our accounts and notes receivable, including premiums receivable, and certain of our other assets, including reinsurance recoverables. However, this ASU is not applicable to the accounting for insurance losses and loss adjustment expenses. Due to the nature of our assets affected by this update, we do not expect it to have a material effect on our financial statements and disclosures. This update is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We will adopt this standard effective January 1, 2020 using the modified retrospective adoption approach. The adoption of this ASU is not expected to have a material effect on the Company’s consolidated financial statements.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In August 2018, the FASB issued ASU 2018-12, Financial Services-Insurance. The new standard: (i) requires that assumptions used to measure the liability for future policy benefits be reviewed at least annually; (ii) defines and simplifies the measurement of market risk benefits; (iii) simplifies the amortization of deferred acquisition costs; and (iv) enhances the required disclosures about long-duration contracts. This update is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact on our financial statements and future disclosures as a result of this update.</span></div><div style="line-height:120%;padding-top:6px;text-align:left;text-indent:30px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In April 2019, the FASB issued ASU 2019-04, Codification Improvements related to Financial Instruments-Credit Losses, Derivatives and Hedging, and Financial Instruments. This update to the accounting standards regarding financial instruments and derivatives and hedging clarifies the accounting treatment for the measurement of credit losses and provides further clarification on previously issued updates. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years.
