Amortization of other intangible assets was $1.6 million and $0.8 million for the three months ended June 30, 2022 and 2021, respectively, and $3.0 million and $1.5 million for the six months ended June 30, 2022 and 2021, respectively.

During the fourth quarter of 2021, the Company reassessed the useful lives of our other intangible assets acquired from recent acquisitions. Given our rebranding efforts, the Company shortened the remaining useful lives of some tradename intangible assets resulting in accelerated amortization prospectively beginning in the fourth quarter of 2021.
