Recent Accounting Pronouncements	Note 3. Recent Accounting Pronouncements Recently Issued Accounting Pronouncements Financial Instruments – Credit Losses. In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments—Credit Losses changing the way credit losses on accounts receivable are estimated. Under current U.S. GAAP, credit losses on trade accounts receivable are recognized once it is probable that such losses will occur. Under this ASU, the Company will be required to estimate credit losses based on the expected amount of future collections which may result in earlier recognition of allowance for doubtful accounts. This ASU will be effective in the first quarter of 2020 and will be adopted using a modified retrospective approach. The Company has evaluated this new guidance and it will not have a material impact on its Consolidated and Combined Financial Statements and related disclosures. Cloud Computing Arrangements. In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, aligning the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs for internal-use software. This ASU will be effective in the first quarter of 2020 and will be adopted on a prospective basis. The Company has evaluated this new guidance and it will not have a material impact on its Consolidated and Combined Financial Statements and related disclosures. Recently Adopted Accounting Pronouncements Revenue Recognition. The FASB amended the FASB Accounting Standards Codification (“ASC”) and created Topic 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, revenue recognition occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. In addition, ASC 606 requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company’s primary source of revenue is the sale of marketplace subscription advertising to car dealerships, which will continue to be recognized ratably over the contract term as the service is provided to the customer. Effective January 1, 2018, the Company adopted ASC 606 using the modified retrospective method. The adoption did not have a material impact on its Consolidated and Combined Financial Statements and related disclosures. For further information, see Note 5 (Revenue). Leases. In February 2016, the FASB issued ASU 2016-02, Leases (ASU 2016-02) in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under current U.S. GAAP. The new guidance requires a lessee to recognize a liability to make lease payments (the “lease liability”) and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 (including interim periods within those periods) using a modified retrospective approach and early adoption is permitted. The Company adopted ASU 2016-02 in the first quarter of 2019 utilizing the modified retrospective transition approach for leases existing at, or entered into after, the beginning of the first quarter of 2019 and did not recast the comparative periods presented in the Consolidated and Combined Financial Statements upon adoption. The Company elected the ‘package of practical expedients’ and did not reassess its prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the short-term lease recognition exemption for all leases that qualify and did not recognize right-of-use assets or lease liabilities for those leases. The Company’s lease agreements are principally related to real estate. The adoption of ASU 2016-02 resulted in the recognition of operating lease assets of $18.2 million and $35.0 million in operating lease liabilities on its Consolidated Balance Sheets. The difference between the operating lease assets and the operating lease liabilities relates to the derecognition of the Company’s deferred rent obligation, which included the impact of a lease incentive received in 2017 related to the 300 South Riverside Lease in Chicago, Illinois and was already recorded on the Consolidated Balance Sheets at the time of the adoption.
