Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. A summary of the changes in the carrying amount of goodwill, by segment, is shown below:


(in millions)	Automotive			Industrial			Total
Balance as of April 30, 2022	$	105.9		$	127.1		$	233.0
Foreign currency translation		(0.3	)		(1.7	)		(2.0	)
Balance as of October 29, 2022	$	105.6		$	125.4		$	231.0

The Company tests goodwill and indefinite-lived intangible assets for impairment on an annual basis as of the beginning of the fourth quarter each fiscal year. In addition, the Company continuously monitors for events and circumstances that could negatively impact the key assumptions used in determining fair value and therefore require interim goodwill impairment testing, including long-term revenue growth projections, profitability, discount rates, volatility in the Company's market capitalization, and general industry, market and macroeconomic conditions. No impairment indicators were identified in the six months ended October 29, 2022.
