Provisions for the impairment of goodwill and/or other intangible assets could arise in a future period due to significant and unanticipated changes in circumstances, such as declines in profitability and cash flow due to long-term deterioration in macroeconomic, industry and market conditions, the loss of key customers, changes in technology or markets, changes in key personnel or litigation, a sustained decrease in share price and/or other events. As of March 30, 2024, the company had no accumulated impairment losses.

The weighted-average amortization periods related to other intangible assets are as follows:


			In Years

The aggregate amortization expense was $6.3 million and $6.9 million for the respective three month periods ended March 30, 2024, and April 1, 2023.
