Intangible Asset, Goodwill and Other [Abstract]

The Company is required to assess goodwill and any indefinite-lived intangible assets for impairment annually, or more frequently if circumstances indicate an impairment may have occurred. The Company performs the annual impairment assessment for each of its reporting units during the third quarter of each year. The reporting unit level is defined at the same level as the Company's operating segments. A company can assess qualitative factors to determine whether it is necessary to perform a quantitative goodwill impairment test. Alternatively, a company may elect to proceed directly to the quantitative goodwill impairment test. In the third quarter of 2025, the Company completed a qualitative impairment assessment and concluded that goodwill was not impaired. As part of its assessment, the Company considered numerous factors, including:

•that the fair value of each reporting unit exceeds its carrying value by a substantial margin based on its most recent quantitative assessment in 2023;

•whether significant acquisitions or dispositions occurred which might alter the fair value of its reporting units;

•macroeconomic conditions and their potential impact on reporting unit fair values;

•actual performance compared with budget and prior projections used in its estimation of reporting unit fair values;

•industry and market conditions; and

•the year-over-year change in the Company’s share price.

Other intangible assets that are not deemed to have an indefinite life are amortized over their estimated lives and assessed for impairment upon the occurrence of certain triggering events in accordance with applicable accounting literature. Based on its assessment, the Company concluded that other intangible assets were not impaired. The Company had no indefinite-lived intangible assets at June 30, 2026 and December 31, 2025.

Changes in the carrying amount of goodwill are as follows:



(In millions)	2026		2025
Balance at January 1,	$	24,337	$	23,306
Goodwill acquired	132		100
Other adjustments (a)	(117)		513
Balance at June 30,	$	24,352	$	23,919

(a)Primarily reflects the impact of foreign exchange.

The goodwill from acquisitions in 2026 and 2025 consists largely of the synergies and economies of scale expected from combining the operations of the Company and the acquired entities and the trained and assembled workforce acquired.

The goodwill acquired in 2026 included approximately $55 million and $51 million in the Risk and Insurance Services and Consulting segments, respectively, which is expected to be deductible for tax purposes.

Goodwill allocated to the Company’s reportable segments at June 30, 2026 is $19.6 billion for Risk and Insurance Services and $4.8 billion for Consulting.

The gross cost and accumulated amortization of other identified intangible assets at June 30, 2026 and December 31, 2025 are as follows:


	June 30, 2026						December 31, 2025
(In millions)	Gross Cost		Accumulated Amortization		Net Carrying Amount		Gross Cost		Accumulated Amortization		Net Carrying Amount
Client relationships	$	7,055	$	2,603	$	4,452	$	7,091	$	2,422	$	4,669
Other (a)	462		409		53		476		399		77
Other intangible assets	$	7,517	$	3,012	$	4,505	$	7,567	$	2,821	$	4,746

(a)Primarily reflects non-compete agreements, trade names and developed technology.

Aggregate amortization expense for the three and six months ended June 30, 2026 was $137 million and $275 million, respectively, compared to $140 million and $279 million, respectively, for the corresponding periods in the prior year.

The estimated future aggregate amortization expense is as follows:


For the Years Ending December 31,
(In millions)	Estimated Expense

2027	507
