Acquisitions, Goodwill, and Intangible Assets Acquisitions, Goodwill, and Intangible Assets
During the nine months ended September 30, 2023, we completed business acquisitions with total purchase consideration of $467 million in cash. Substantially all of the total consideration was allocated to $88 million of intangible assets and $366 million of goodwill. Goodwill generated from these business acquisitions completed was primarily attributable to expected synergies and potential monetization opportunities. The amount of goodwill generated that was deductible for tax purposes was not material. Acquisition-related costs were immaterial and were expensed as incurred. Pro forma historical results of operations related to these business acquisitions have not been presented because they are not significant to our condensed consolidated financial statements, either individually or in aggregate. We have included the financial results of these acquired businesses in our condensed consolidated financial statements from their respective dates of acquisition.

Changes in the carrying amount of goodwill by reportable segment for the nine months ended September 30, 2023 are as follows (in millions):
