Goodwill Amortization | GAAP vs. Tax Accounting Criteria (2024)

Goodwill Accounting Guidelines

Goodwill represents the excess of purchase price over the fair market value of a company’s net assets.

If a businessis simply a collection of assets, why would an acquirer pay morethan the fair market value of thatcollection of assets?

There are two good reasons:

1. The value of a business can be greater than the sum of the fair value of each of its individual assets. For example, Pepsi’s brand is valuable on its own,and is far more valuable when combined withits distribution system.
2. Synergies (cost savings) for strategic deals. (Note that overpayment due to an incorrect estimation of synergies is also a common reason an M&A deal can fail.)

Goodwill Rules: Tax vs. Book Accounting

If you aren’t familiar with the basic calculation of goodwill, please read ourM&A accounting primerbefore moving on.

A challenge of goodwill accounting is that it’s treatedoneway under tax accounting and another under GAAP (“book”) accounting. Below, we lay out the basic differences:

1. Goodwill Tax Accounting

M&A transactions can be structured as either a stock sale or an asset sale/338(h)(10) elections. The structure determines goodwill’s tax implications:

• Asset Sale/338: Any goodwill created in an acquisition structured as an asset sale/338 is tax-deductible and amortizable over 15 years, along with other intangible assets that fall under IRC section 197.
• Stock Sale: Any goodwill created in an acquisition structured as a stock sale is non-tax-deductible and non-amortizable.

At the risk of stating the obvious, tax-deductible goodwill is attractive to an acquirer because it will reduce acquirer taxes going forward after the acquisition. So, all else being equal, acquisitions structured as asset sales/338 elections are more attractive to acquirers.

2. GAAP Book Accounting

Under GAAP (“book”) accounting, goodwill is not amortized but rather tested annually for impairmentregardless of whether the acquisition is an asset/338 or stock sale.

Acaveat is that under GAAP, goodwill amortization is permissible for private companies.The purpose of thisaccommodation is to reduce the costliness of annual impairment testing on private companiesthat lack the internal accounting resources needed to performthe tests. It’s important to note that not all private companiestakethis election because they’d have to restate all of their financialsif they everwent public.
