Enterprise Value And Deal Accounting
This conversation was generated using Cook'd AI's career assistant and reviewed by Fallon Han from our editorial team for accuracy.
I'm a senior undergrad in the UK studying economics and I'm applying for middle-market M&A advisory roles that need sponsorship. Please test me on how to explain enterprise value, purchase accounting, and merger synergies clearly. I want follow-up probes too, because I need to defend each assumption under pressure.

Absolutely. I'll keep it technical and push on your assumptions like a real interviewer.
First question: walk me through enterprise value from first principles. Define it, explain why it's used in M&A, and tell me what gets added to equity value to get to EV. Then I will challenge any weak spots.
Enterprise value is the value of the whole operating business, so it reflects the value to all capital providers, not just shareholders. In M&A it's useful because it standardises valuation across targets with different capital structures.
To get from equity value to EV, I would add net debt, meaning debt and debt-like items less cash, and also include minority interest and preferred equity if relevant. I would also adjust for associates if they are material. The core idea is that EV captures the value of the operations before financing effects.

Good start. Now tighten it.
Two follow-ups: first, why do we subtract cash if cash is an asset? Second, when you say debt-like items, give me three examples an interviewer might expect in a live deal. Keep it concise but precise.
We subtract cash because excess cash is not needed to run the operations and can be used to repay debt or distributed to shareholders after closing, so the buyer is not really paying for it as part of core operations.
Examples of debt-like items would be lease liabilities, pension deficits, and unpaid transaction bonuses or accrued management incentives if they are treated as debt-like in the transaction. Depending on the deal, there could also be factoring or litigation provisions if they are sufficiently debt-like.

Better. Now let's move to purchase accounting.
Assume a buyer acquires 100 percent of a target for cash. Explain what happens under purchase accounting on day one. I want you to cover the fair value step-up, goodwill, and why book value usually changes after the deal. Then I will push on deferred tax and intangibles.
Under purchase accounting, the target's assets and liabilities are revalued to fair value on the acquisition date. So if any assets are worth more than their book value, they get stepped up, and liabilities are also recorded at fair value.
The difference between the purchase price and the fair value of net identifiable assets becomes goodwill. Book value changes because accounting is resetting the acquired balance sheet to reflect what the buyer actually paid for the business rather than the target's historical carrying values.
This also creates new depreciation and amortisation charges on the stepped-up assets, which can affect post-deal earnings.

Good. Now defend that more carefully.
Why might deferred tax liabilities appear after a purchase accounting step-up? And what is the practical difference between goodwill and identifiable intangibles such as customer relationships or brand? I am looking for clear logic, not textbook wording.
Deferred tax liabilities can appear because the fair value of certain assets, like intangibles or PP and E, may be higher than their tax base. The accounting step-up creates a temporary difference between book value and tax value, so deferred tax is recorded for the future tax impact.
The practical difference is that identifiable intangibles are assets the buyer can separate or reliably value on day one, such as customer relationships, developed technology, or a brand. Goodwill is the residual amount that captures things you cannot separately identify, like workforce quality, synergies, or the premium paid over fair value net assets.

Last topic: merger synergies.
Explain the difference between revenue and cost synergies, then tell me how you would sanity-check whether they are actually real. I also want you to tell me one reason why an M&A model can overstate synergies if the analyst is sloppy. Assume the interviewer is skeptical and wants you to defend every assumption.
