Table of Contents Core Logic, Inc. Notes to the Consolidated Financial Statements For the Years Ended December 31, 2020, 2019 and 2018 Property and Equipment Capitalized Data and Database Development Costs, Net Purchase Accounting Goodwill 58 Property and equipment is recorded at cost and includes computer software acquired or developed for internal use and for use with our products. Software development costs include certain payroll-related costs of employees directly associated with developing software and payments to third parties for completed or developing software. We begin capitalizing qualifying software development costs on a project when the preliminary project stage has been completed and management has authorized further funding for completion. Capitalization ends once a project is substantially complete and the software is ready for its intended use. Costs incurred in the planning and post-implementation phases of software developing are expensed as incurred. Depreciation on buildings and on furniture and equipment is computed using the straight-line method over estimated useful lives of 25 to 40, and 3 to 10 years, respectively. Capitalized software costs are amortized using the straight-line method over estimated useful lives of 3 to 20 years. Leasehold improvements are amortized over the lesser of the estimated useful life or the lease term. Capitalized data and database development costs represent our cost to acquire or develop the proprietary databases of information for client use. The costs are capitalized from the time the third-party data is acquired until the information is ready for use, assuming both the preliminary project stage is complete and management has authorized funding for the completion of the data project. Property and eviction data costs are amortized using the straight-line method over estimated useful lives of 5 to 25 years. The carrying value of our flood data zone certification was $55.4 million as of December 31, 2020 and 2019. Because properly maintained flood zone databases have indefinite lives and do not diminish in value with the passage of time, no provision has been made for depreciation or amortization. We periodically analyze our assets for impairment. This analysis includes, but is not limited to, the effects of obsolescence, duplication, demand and other economic factors. See further discussion in  Note 6  –  Capitalized Data and Database Development Costs, Net. The purchase method of accounting requires companies to assign values to assets and liabilities acquired based upon their fair values at the acquisition date. In most instances, there are not readily defined or listed market prices for individual assets and liabilities acquired in connection with a business, including intangible assets. The determination of fair value for assets and liabilities in many instances requires a high degree of estimation. The valuation of intangible assets, in particular, is very subjective. We generally obtain third-party valuations to assist us in estimating fair values. The use of different valuation techniques and assumptions could change the amounts and useful lives assigned to the assets and liabilities acquired and related amortization expense. Every fourth quarter, we perform an annual impairment test for goodwill and other indefinite-lived intangible assets for each reporting unit: Property Intelligence & Risk Management Solutions ("PIRM") and Underwriting & Workflow Solutions ("UWS"). We may also perform an impairment test on an interim basis if an indicator of impairment is present. In assessing the overall carrying value of our goodwill and other intangibles, we could first assess qualitative factors to determine whether the fair value of a reporting unit is less than its carrying amount. Examples of such events or circumstances include the following: cost factors, financial performance, legal and regulatory factors, entity specific events, industry and market factors, macroeconomic conditions and other considerations. For goodwill, if we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then quantitative impairment testing is performed utilizing a combination of the income and market approach. We could also elect to perform a quantitative impairment test without first assessing qualitative factors. If the fair value of a reporting unit exceeds its carrying value, then goodwill is not considered impaired and no additional analysis is required. However, if the book value of a reporting unit is greater than its fair value, an impairment loss is recorded for the excess. Determining the fair value of a reporting unit is judgmental and requires assumptions and estimates of many critical factors, including revenue growth rates, cost of services, selling, general and administrative expenses, market multiples, and discount rates.
