GOODWILL AND INTANGIBLE ASSETS
Goodwill The majority of the goodwill recorded as of December 31, 2022 and 2021, related to the April 1, 2015, acquisition of a controlling interest in ARX. During 2022, we performed an impairment test of our goodwill allocated to the ARX reporting unit and recorded an impairment loss of $224.8 million, which is disclosed as a separate line item in our consolidated statements of comprehensive income. The impairment loss was fully allocated to our Property operating segment. There were no previously recorded goodwill impairment losses on any of the outstanding goodwill.
The indicators of impairment primarily related to the magnitude of weather events relative to forecasted expectations during the first half of 2022, as well as other factors impacting our plans to restore our Property business to target profitability in a timely fashion and the subsequent reduced forecasted profitability of ARX.
The quantitative goodwill impairment assessment consisted of comparing the fair value of the reporting unit to its carrying value. To determine the fair value of a reporting unit, we use a discounted cash flow model. The model uses assumptions including, but not limited to, discount rate, forecasted growth, profitability, investment return, and capital requirements. The assumptions and estimates were consistent with those we believe other non-related marketplace participants would use and were based on management’s best estimates at the time of the analysis. The calculated fair value of the ARX reporting unit was below its carrying value at June 30, 2022, which resulted in recording the goodwill impairment. There was no indication of impairment on the remaining $227.9 million of goodwill, of which 98% was attributable to our Personal Lines Agency business and related to the ARX acquisition.
Intangible Assets The following table is a summary of the net carrying amount of other intangible assets as of December 31:

1 Indefinite-lived intangible assets are comprised of state insurance and agent licenses. State insurance licenses were previously subject to amortization under superseded accounting guidance and have $0.6 million of accumulated amortization for both years presented.
Intangible assets subject to amortization for the years ended December 31, consisted of the following:

About Goodwill & Intangibles Disclosures

Goodwill and intangible asset disclosures reveal the premium paid in acquisitions and how management assesses whether that premium retains its value. Since goodwill is no longer amortized under US GAAP, the annual impairment test is the only mechanism that adjusts carrying values downward — making the assumptions behind that test critically important for investors.

Key signals: a history of goodwill impairments suggests management consistently overpays for acquisitions. Watch the gap between reporting unit fair value and carrying amount — when fair value exceeds carrying amount by less than 10-20%, a small decline in business performance could trigger a write-down. For finite-lived intangibles, examine useful life assumptions across customer relationships, technology, and trade names; aggressive estimates inflate near-term earnings. Compare total intangibles-to-total-assets ratios against peers to assess acquisition dependency. Rising goodwill as a percentage of equity can signal balance sheet fragility.
