Why do business combinations create deferred tax liabilities, and how does this affect goodwill?

This is genuinely one of the more mind-bending areas of FRA because the DTL and goodwill are interdependent. Let me untangle it.

Why Fair Value Step-Ups Create DTLs

When Meridian acquires Keystone, the consolidated balance sheet reflects Keystone's assets at fair value. But Keystone's TAX basis remains at the old book value (in most acquisitions structured as stock deals).

The $45M DTL represents future taxable income that will arise as these assets are depreciated/amortized (higher book depreciation than tax depreciation creates taxable income when it reverses).

How DTLs Increase Goodwill

The DTL is a liability recognized in the acquisition. Since goodwill = Consideration - Net identifiable assets at FV, adding a liability reduces net assets and increases goodwill.

The DTL increased goodwill by $45M.

The 'Circular' Issue

Students worry about circularity: does the DTL on goodwill create more goodwill, which creates more DTL, and so on?

The answer is NO. Under both US GAAP and IFRS, no deferred tax is recognized on goodwill arising from initial recognition in a business combination. This is the initial recognition exception. It breaks the circularity.

Exception to the Exception:

In an asset acquisition (as opposed to a business combination), the initial recognition exception may not apply, and the analysis differs. But for CFA Level II, focus on business combinations where goodwill DTL is prohibited.

Post-Acquisition Impact

As the stepped-up assets are depreciated/amortized:

• Book depreciation > Tax depreciation → the temporary difference reverses
• The DTL decreases each year
• Income tax expense (book) decreases as the DTL reversal creates a deferred tax benefit

Exam tip: A common question gives you the purchase price, net assets, and fair value adjustments, and asks you to compute goodwill. If you forget to include the acquisition DTL, your goodwill will be too low.
