Section 338(h)(10) Valuation: The 'Step-Up' Math

TL;DR: When a company executes a Section 338(h)(10) Election, they are resetting the "Tax Value" of the company to the "Purchase Price." This is called a Step-Up in Basis. It allows the Buyer to take an old, fully depreciated factory (worth $0 on the books) and turn it back into a $10 Million asset for tax purposes. This "Magic Math" creates a Tax Shield that can be worth 20% to 30% of the entire deal value, proving that in the world of M&A, the "Tax Structure" of the deal is just as important as the cash paid.

Introduction: The "Basis" Concept

In tax law, your "Basis" is what you paid for something.

• If you buy a machine for $1,000, your basis is $1,000.
• Every year, you "depreciate" that machine, lowering your taxes.
• After 5 years, your "Basis" is Zero. You get no more tax breaks.

When a Buyer buys that company, they want to "Step-Up" that basis back to $1,000 (or more) so they can start the tax breaks all over again.

The "ADSP" Calculation (The Math of the Sale)

To find the new tax value of the assets, the IRS uses the Aggregate Deemed Sales Price (ADSP) formula. ADSP = G + L + (Tax Liability).

• G: The Grossed-Up price paid for the stock.
• L: The Target company's liabilities (debt) that the Buyer is taking over.

This formula determines the "Fictional" price the Target sold its assets for.

The "Class" Allocation (Where the Money Goes)

The IRS doesn't let you put all the value on whatever you want. You must follow the Residual Method (7 Classes):

• Class I-IV: Cash, Stocks, and Accounts Receivable. (Value = Face Value).
• Class V: Fixed Assets (Land, Factories, Equipment).
• Class VI: Intangible Assets (Patents, Trademarks).
• Class VII: Goodwill.

The Buyer wants to put as much money as possible into Class V and VI because they can depreciate those quickly (5-15 years). Money in Class VII (Goodwill) must be amortized over 15 years, which is slower but still very valuable.

The "Net Present Value" (NPV) of the Election

Why is this worth millions? Imagine a $100 Million deal. A 338(h)(10) election creates a $50 Million "Step-Up" in assets.

• The Tax Rate: 21%.
• The Total Saving: $50M x 0.21 = $10.5 Million in total cash savings over 15 years.
• The NPV: When you account for the "Time Value of Money," that tax shield is worth about $7 Million today.

A smart Buyer will pay $102 Million for a company with a 338(h)(10) election rather than $100 Million for one without it, because the tax math makes it a cheaper deal in the long run.

The "Recapture" Tax (The Seller's Cost)

The math only works if the Seller agrees. Because the IRS treats this as an "Asset Sale," the Seller has to pay Ordinary Income Tax on the "Recapture" of the old depreciation. This is much more expensive than the "Capital Gains Tax" they would pay on a normal stock sale. The Negotiation: The Buyer must "Gross-Up" the Seller's price to cover this extra tax. The election only happens if the Buyer's Saving is bigger than the Seller's Extra Cost.

Conclusion

Section 338(h)(10) Valuation is the "Invisible Profit" of M&A. It proves that in high-stakes capital, a company is not just a collection of employees and products, but a "Tax Asset" that can be optimized for cash flow. By using the Residual Method to re-value a Target's balance sheet, corporate leaders successfully "Recycle" the tax breaks of the past to fund the growth of the future, ultimately proving that in the end, the most powerful math in a merger is the one that happens on the tax return. 引导语：第 338(h)(10) 条估值（Section 338(h)(10) Valuation）是并购中的“无形利润”。它证明了，在风险极高的资本世界中，一家公司不仅仅是员工和产品的集合，更是一个可以针对现金流进行优化的“税务资产”。通过利用剩余法对目标公司的资产负债表进行重新估值，企业领导者成功地“回收”了过去的税收减免，用以资助未来的增长，最终证明，到头来一场合并中最强大的数学是发生在纳税申报单上的那一个。
