Goodwill and intangible assets. We allocate the purchase price of acquired businesses to their identifiable tangible assets and liabilities, such as accounts receivable, inventory, property, plant and equipment, accounts payable and accrued liabilities. We also allocate a portion of the purchase price to identifiable intangible assets, such as non-compete agreements, trademarks, trade names, patents, technology and customer relationships. Allocations are based on estimated fair values of assets and liabilities. We use all available information to estimate fair values including quoted market prices, the carrying value of acquired assets, and widely accepted valuation techniques such as discounted cash flows. Certain estimates and judgments are required in the application of the fair value techniques, including estimates of future cash flows, selling prices, replacement costs, economic lives and the selection of a discount rate, as well as the use of “Level 3” measurements as defined in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820 Fair Value Measurements and Disclosure (“ASC 820”). Deferred taxes are recorded for any differences between the assigned values and tax bases of assets and liabilities. Estimated deferred taxes are based on available information concerning the tax bases of assets acquired and liabilities assumed and loss carryforwards at the acquisition date, although such estimates may change in the future as additional information becomes known. Any remaining excess of cost over allocated fair values is recorded as goodwill. We typically engage third-party valuation experts to assist in determining the fair values for both the identifiable tangible and intangible assets. The judgments made in determining the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, could materially impact our results of operations.
Goodwill and intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but are instead tested for impairment at least annually in accordance with the provisions of the ASC 350 Intangibles—Goodwill and Other (“ASC 350”). Intangible assets with estimated useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment in accordance with ASC 350. We assess goodwill for impairment at the reporting unit level, which we have determined to be the same as our operating segments. Each reporting unit has goodwill relating to past acquisitions.
Prior to January 1, 2017, the test for impairment was a two-step process that involved comparing the estimated fair value of each reporting unit to the reporting unit’s carrying value, including goodwill. If the fair value of a reporting unit exceeded its carrying amount, the goodwill of the reporting unit was not considered impaired; therefore, the second step of the impairment test would not be deemed necessary. If the carrying amount of the reporting unit exceeded its fair value, we would then perform the second step to the goodwill impairment test, which involved the determination of the fair value of a reporting unit’s assets and liabilities as if those assets and liabilities had been acquired/assumed in a business combination at the impairment testing date, to measure the amount of goodwill impairment loss to be recorded. However, effective January 1, 2017 we prospectively adopted a new accounting principle that eliminated the second step of the goodwill impairment test. Therefore, for goodwill impairment tests occurring after January 1, 2017, if the carrying value of a reporting unit exceeds its fair value, we measure any goodwill impairment losses as the amount by which the carrying amount of a reporting unit exceeds its fair value, not to exceed the total amount of goodwill allocated to that reporting unit. Our goodwill annual test date is December 1 of each year.
In the third quarter of the year ended December 31, 2017, we determined that there were sufficient indicators to trigger an interim goodwill impairment analysis, primarily due to a 43% decrease in the Company’s stock price during the quarter, market softness and our financial results. This interim goodwill impairment test was prepared as of July 31, 2017. The fair values of the reporting units were determined using a combination of income and market approaches. The income approach was based on discounted cash flow models with estimated cash flows based on internal forecasts of revenue and expenses over a five-year period plus a terminal value period. The income approach estimated fair value by discounting each reporting unit’s estimated future cash flows using a discount rate that approximated our weighted-average cost of capital. Major assumptions applied in an income approach include forecasted growth rates as well as forecasted profitability by reporting unit. Additionally, we considered two market approaches that used multiples, based on observable market data, of a combination of historical and projected financial metrics of our reporting units, to arrive at fair value. We applied weightings to each of the income and the two market approaches. The fair value derived from these approaches, in the aggregate, approximated our market capitalization.
The July 31, 2017 interim goodwill impairment test indicated impairment as the carrying values of the MS and IHT reporting units exceeded their fair values. The carrying value of the MS reporting unit exceeded its fair value by $54.1 million and the carrying value of the IHT reporting unit exceeded its fair value by $21.1 million, resulting in a total impairment loss of $75.2 million. The fair values of the reporting units are “Level 3” measurements as defined in Note 11. The fair value of the Quest Integrity reporting unit significantly exceeded its carrying value.
For our annual goodwill impairment tests as of December 1, 2017 and December 1, 2018, we elected to perform qualitative assessments to determine if it was more likely than not (that is, a likelihood of more than 50 percent) that the fair values of our reporting units were less than their respective carrying values as of the test dates. Our qualitative assessment for the December 1, 2017 test considered relevant events and circumstances occurring since the July 31, 2017 quantitative impairment test date that could affect the fair value or carrying amount of the reporting units, while our qualitative assessment for the December 1, 2018 test considered relevant events and circumstances occurring since the December 1, 2017 qualitative impairment test date. Specifically, we considered changes in the Company’s stock price, industry and market conditions, our internal forecasts of future revenue and expenses, any significant events affecting the Company and actual changes in the carrying value of our net assets. After considering all positive and negative evidence for the assessments as of both of these dates, we concluded that it was not more likely than not that our carrying values exceeded fair values and, as such, no additional impairment was indicated.
There was $281.7 million and $284.8 million of goodwill at December 31, 2018 and 2017, respectively. A summary of goodwill is as follows (in thousands):
