Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a business acquisition. Following an acquisition, we perform an analysis to value the acquired company’s tangible and identifiable intangible assets and liabilities. With respect to identifiable intangible assets, we consider backlog, non-compete agreements, client relationships, trade names, patents and other assets. We amortize our intangible assets based on the period over which the contractual or economic benefits of the intangible assets are expected to be realized. We assess the recoverability of the unamortized balance of our intangible assets when indicators of impairment are present based on expected future profitability and undiscounted expected cash flows and their contribution to our overall operations. Should the review indicate that the carrying value is not fully recoverable, the excess of the carrying value over the fair value of the intangible assets would be recognized as an impairment loss. As of the acquisition date, goodwill consisted primarily of synergies resulting from the combination, expected expanded opportunities for growth and production, and savings in corporate overhead costs.

We perform our annual goodwill impairment review during our fourth quarter as of October 1. In addition, we regularly evaluate whether events and circumstances have occurred that may indicate a potential change in recoverability of goodwill. We perform interim goodwill impairment reviews between our annual reviews if certain events and circumstances have occurred, including a deterioration in general economic conditions, an increased competitive environment, a change in management, key personnel, strategy or customers, significant or unusual changes in market capitalization, negative or declining cash flows, or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods. During the three months ended March 31, 2020 we considered the impact of COVID-19 and the resulting economic impact a triggering event and performed a goodwill impairment review.

When assessing goodwill for impairment, the Company may first assess qualitative factors to evaluate whether it is more likely than not that the fair value of a reporting unit is less than it’s carrying amount or elect to bypass such assessment. If it is determined that it is more likely than not that the fair value of a reporting unit is less than it’s carrying value, or the Company elects to bypass such assessment, the Company then determines the fair value of each reporting unit. The estimate of the fair value of each reporting unit is based on a projected discounted cash flow model that includes significant assumptions and estimates including the Company's discount rate, growth rate and future financial performance as well as a market multiple model based upon similar transactions in the market. Assumptions about the discount rate are based on a weighted average cost of capital built up from various interest rate components applicable to the Company. Assumptions about the growth rate and future financial performance of a reporting unit are based on the Company's forecasts, business plans, economic projections and anticipated future cash flows. Market multiples are derived from recent transactions among businesses of a similar size and industry. The fair value of each reporting unit is compared to the carrying amount of the reporting unit. If the carrying value of the reporting unit exceeds the fair value, then an impairment loss is recognized for the difference. For the three months ended March 31, 2020 the Company determined that there is no impairment to goodwill. As of March 31, 2020 and December 31, 2019, the balance of goodwill was $1.7 million. This goodwill is reflected within our Real Estate Services segment
