Goodwill as of September 30, 2023	$	614.4	$	1,361.9	$	1,976.3

(1) Goodwill acquired related to the 2023 Acquisitions. We expect substantially all of the recognized goodwill related to the 2023 Acquisitions not to be deductible for income tax purposes.

In connection with the 2023 Acquisitions, we acquired approximately $88 million of identifiable finite-lived intangible assets, which consisted of customer relationships, patented and other developed technology, and trade names and trademarks. We utilized the income approach to estimate the fair values of acquired identifiable intangibles, primarily using Level 3 inputs. We applied significant judgment in determining the fair value of intangible assets, which included our estimates and assumptions with respect to future revenue and related profit margins, customer retention rates, technology migration curves, royalty rates, discount rates and economic lives assigned to the acquired intangible assets.

The table below summarizes the amounts and weighted average useful lives of these intangible assets as of the respective acquisition dates.


	Amount (in millions)		Weighted average amortization period (in years)
Customer relationships	$	64.9	11
Patented and other developed technology	19.7		7
Trade names and trademarks	3.0		6

Amortization expense for all finite-lived intangible assets resulting from business acquisitions, including the 2023 Acquisitions, was $22.1 million and $20.4 million for the three months ended September 30, 2023 and October 1, 2022, respectively, and $64.2 million and $61.5 million for the nine months ended September 30, 2023 and October 1, 2022, respectively.

Estimated future amortization expense related to existing finite-lived intangible assets for the remainder of fiscal year 2023 and for each of the next four fiscal years and thereafter is shown below. These amounts include the impact of the 2023 Acquisitions.
