1	Adjustments to preliminary goodwill for Royal Adhesives and Adecol as of September 1, 2018.

As discussed in Note

17,

as of the beginning of fiscal

2018,

we modified our operating segment structure by allocating the Royal Adhesives segment into each of the

five

other segments. This resulted in a change in our reporting units. We allocated goodwill to our reporting units using the relative fair value approach.

Balances of amortizable identifiable intangible assets, excluding goodwill and other non-amortizable intangible assets, are as follows:

	September 1, 2018
Amortizable Intangible Assets	Purchased Technology and Patents			Customer Relationships			All Other			Total
Original cost	$	130,971		$	956,923		$	109,304		$	1,197,198
Accumulated amortization		(35,024	)		(184,777	)		(47,693	)		(267,494	)
Net identifiable intangibles	$	95,947		$	772,146		$	61,611		$	929,704

	December 2, 2017
Amortizable Intangible Assets	Purchased Technology and Patents			Customer Relationships			All Other			Total
Original cost	$	132,495		$	968,060		$	110,576		$	1,211,131

Net identifiable intangibles	$	105,017		$	823,096		$	73,159		$	1,001,272
