Amortization
Amortization is a financing concept describing a form of capital or debt structure used to fund M&A acquisitions.
Full Definition
Amortization in M&A has two related but distinct meanings that come up constantly in deal analysis. The first is debt amortization — the scheduled repayment of principal on acquisition loans over time. The second is intangible asset amortization — the accounting treatment that spreads the cost of acquired intangible assets (customer relationships, non-competes, trade names, patents) across their useful lives on the income statement.
Debt amortization: When a buyer finances an acquisition with a term loan, the loan agreement will specify an amortization schedule — typically quarterly or annual principal payments over the loan's term. SBA 7(a) loans, for example, amortize over 10 years on business acquisitions. The amortization payments reduce the outstanding loan balance over time, building equity. But they also consume cash that could otherwise fund operations or growth — which is why "debt service" is such a critical figure in acquisition cash flow modeling. DSCR (Debt Service Coverage Ratio) divides EBITDA by total debt service (interest + principal) and must typically be 1.25x or higher for lenders to approve the loan.
Intangible asset amortization: In purchase price allocation (PPA), the purchase price is allocated across acquired assets. A significant portion often goes to intangible assets identified in the PPA — customer lists, brand value, technology, non-competes. These intangibles are then amortized (expensed) over their useful lives, typically 5–15 years, running through the income statement as an amortization expense. This is a non-cash charge that reduces reported net income but not cash flow. Goodwill is not amortized under GAAP (it's tested annually for impairment instead); however, for tax purposes under IRC §197, acquired intangibles including goodwill are amortized over 15 years in asset deals — creating a real tax shield.
EBITDA and amortization: The "A" in EBITDA stands for amortization, meaning EBITDA adds back amortization expense to operating income. This is why EBITDA is the preferred metric in acquisition pricing — it removes the noise of post-acquisition intangible amortization, making pre- and post-acquisition financials more comparable.
Seller vs. Buyer Perspective
Amortization primarily affects you as a seller in two ways. First, if your company has prior debt on the books, understand how that amortization schedule interacts with the working capital target set at closing — some of that debt will need to be repaid at close. Second, in an asset sale, the buyer gets to amortize acquired intangibles and goodwill over 15 years for tax purposes. This tax shield has real value to buyers, which is part of why they sometimes pay higher prices in asset deals (where they can step up the tax basis) versus stock deals.
Model both types of amortization in your acquisition underwriting. On debt amortization: calculate your annual principal payments and ensure your projected EBITDA comfortably covers both interest and principal (DSCR ≥ 1.25x, ideally 1.5x+). On intangible amortization: after completing a preliminary PPA estimate, calculate the annual amortization expense to understand the gap between EBITDA and reported net income. This matters for bank covenants that may be tied to net income rather than EBITDA, and for lenders who want to see GAAP financials.
Real-World Example
A buyer acquires a business for $5M in an asset deal. The PPA allocates $1M to customer relationships (10-year life) and $2.5M to goodwill. The buyer amortizes $100K/year of customer relationships through the income statement (GAAP non-cash expense), and deducts $233K/year of goodwill amortization on their tax return (§197, 15-year amortization). The tax deduction generates approximately $82K in annual tax savings at a 35% effective rate — over 15 years, a present value of roughly $650K.
Why It Matters & Common Pitfalls
- !DSCR calculations must include amortization. Lenders define debt service as interest plus required principal payments. Acquisitions that look cash-flow positive before debt amortization can be squeezed after — particularly in years with high amortization payments on shorter-term debt tranches.
- !Purchase price allocation determines amortization amounts. PPA is done by a valuation firm after close, but buyers should estimate it before close to forecast amortization expense and tax shields. Surprises in PPA can affect financial covenants in the first post-close reporting period.
- !Goodwill amortization differs for tax vs. GAAP. Under GAAP, goodwill is not amortized — it's tested for impairment. Under §197 tax rules (asset deals), goodwill is amortized over 15 years. This difference between GAAP income and taxable income confuses first-time acquirers and needs to be modeled explicitly.
- !Balloon payments vs. full amortization. Some acquisition loans don't fully amortize over their term — they have a balloon payment due at maturity. Model the refinancing risk: will you be able to refinance the balloon at maturity, and at what rate?
