The following table sets forth the changes in the carrying amount of goodwill:

	(in thousands)
Balance as of December 31, 2021 (1)	$	3,270,192
Acquisitions		66,099
Balance as of June 30, 2022 (1)	$	3,336,291

(1) Goodwill is presented net of accumulated impairment losses of $44.6 million.

In 2022, the change in the carrying amount of goodwill is attributable to the acquisitions completed during the year. As of June 30, 2022, no triggering events have occurred. The amount allocated to goodwill is attributable to the assembled workforce, synergies and expected growth from the expanded product and service offerings of acquisitions. The $66.1 million of goodwill recognized from the current year acquisitions is expected to be deductible for tax purposes and will be amortizable ratably over a 15-year period for tax purposes.
