FRIs M&A Asset Deal considered a business combination under IFRS 3?

Hello, Is M&A Asset Deal considered a business combination under IFRS? I the stock deal, recognised tangible and intangible assets are being written up to their FV. Some intangible assets are being recognised at their FV. The diffrence between the consideration and the value of the assets (the written up value) is Goodwill. (The procedure also known as purchase price allocation) My question is what happens in an asset deal. In asset deal ther is no consolidation but rather assets are bein taken onto the balance sheet of the acquirer. Are already recognised assets from the seller's balance sheet being written up? Are seller's internally generated intangible assets being recognised? Thank you.
