10. Goodwill and Other Intangible Assets
We test each of our reporting units for goodwill impairment annually at October 1st, or upon a triggering event, in accordance with ASC Topic 350, “Intangibles – Goodwill and Other.” We performed the 2025, 2024 and 2023 annual assessments as of October 1 and determined that no impairment existed as the estimated fair value of our reporting units was in excess of their carrying value.
As of January 1, 2025, we reorganized our business into four reportable segments (see Note 20 – Segments for further discussion). This changed the composition of our reporting units which resulted in the reallocation of goodwill from our Advisory Services and Global Workplace Solutions reportable segments to our newly created BOE and Project Management reportable segments as of January 1, 2025. Additionally, the change in composition of our reporting units was considered a triggering event requiring an interim goodwill impairment test as of January 1, 2025. We determined that no impairment existed as the estimated fair values of our reporting units were in excess of their respective carrying values, both before and after the reorganization.
The following table summarizes the changes in the carrying amount of goodwill for the years ended December 31, 2025 and 2024 (dollars in millions):

Indefinite-lived intangible assets include management contracts identified as a result of the ING Group N.V. (ING) Real Estate Investment Management (REIM) operations in Europe and Asia, as well as substantially all of Clarion Real Estate Securities (CRES) acquisition in 2011 (collectively referred to as the REIM Acquisitions) relating to relationships with open-end funds, a trademark separately identified as a result of the CBRE Services, Inc. (CBRE Services) in 2001 (the 2001 Acquisition), a trade name separately identified in connection with the REIM Acquisitions and a trademark separately identified as part of the Turner & Townsend transaction.
Customer relationships relate to existing relationships acquired through acquisitions mainly in our BOE segment that are being amortized over useful lives of up to 20 years.
Mortgage servicing rights represent the carrying value of servicing assets in the U.S. in our Advisory Services segment. The mortgage servicing rights are being amortized over the estimated period that net servicing income is expected to be received, which is typically up to 10 years. See Mortgage Servicing Rights discussion within Note 2 – Significant Accounting Policies for additional information.
Amortizable trademarks are primarily from our 2015 acquisition of the Global Workplace Solutions business from Johnson Controls, Inc., which are being amortized over 20 years.
Amortizable management contracts consist primarily of asset management contracts relating to relationships with closed-end funds and separate accounts in the U.S., Europe and Asia that were separately identified as a result of the REIM Acquisitions. These management contracts have been fully amortized.
Other amortizable intangible assets mainly represent upfront transition costs incurred to obtain or fulfill contracts prior to services being rendered which primarily get amortized to cost of revenue over the life of the associated contract. It also includes a backlog and management agreements identified as intangible assets from the Turner & Townsend and Industrious acquisitions.
Amortization expense related to intangible assets, excluding amortization of transition costs, was $393 million, $363 million and $322 million for the years ended December 31, 2025, 2024 and 2023, respectively. The estimated annual amortization expense, excluding amortization of transition costs, for each of the years ending December 31, 2026 through December 31, 2030 and thereafter approximates $376 million, $322 million, $292 million, $260 million, $236 million and $885 million, respectively.
