Purchase Consideration and Payment Methods in Mergers

Updated 11 October 2026 · Fact-checked

Purchase consideration is the total value the acquirer gives to the target's shareholders, in cash, shares or both. To solve a question, add each component at fair value, compare the per-share value with the unaffected market price to get the premium, then find the acquirer's NPV as synergy minus the cost of the deal.

Understand Purchase Consideration and Payment Methods

Purchase consideration is what the acquirer pays to get control of the target. It can be cash, the acquirer's own shares, debt instruments, or a mix. In exams you value every part at its fair value on the deal date, not at face value.

The premium paid is the extra amount over the target's unaffected market price. Acquirers pay it because they expect synergy and control benefits. If the premium is more than the synergy, the acquirer's shareholders lose value.

In a cash deal, target shareholders get a fixed amount and leave. The acquirer keeps all the synergy and carries all the risk. The cost to the acquirer is simply cash paid minus the target's standalone value.

In a stock deal, target shareholders get shares of the acquirer and become part owners of the combined firm. They share in the synergy and also in the risk. The cost is not fixed. It depends on the value of the combined firm after the deal, so you must compute the new share price.

The decision rule is simple. Compute the NPV of the merger to the acquirer's shareholders for each payment method and choose the one with the higher NPV, subject to the target accepting it. Also check whether the premium is fair to the target's shareholders.

Key rules to remember

Purchase consideration: PC = Cash paid + (Shares issued × fair value per share) + fair value of other payments; Use fair value on the deal date. Payments made to the target's shareholders form the consideration.
Shares issued under an exchange ratio: New shares = Target shares × Exchange ratio; Exchange ratio is the number of acquirer shares given per target share.
Premium per share: Premium = Offer value per share − Unaffected market price per share; Use the price before the deal news leaked or was announced.
Premium percentage: Premium % = Premium per share ÷ Unaffected market price × 100; Total premium = premium per share × number of target shares.
Synergy: Synergy = V(combined) − V(acquirer) − V(target); All values are standalone values before the deal. Synergy is the gain from combining.
Cost of a cash offer: Cost = Cash paid − V(target standalone); Cost is the premium over standalone value.
Cost of a stock offer: Cost = (New shares ÷ Total shares after deal) × V(combined) − V(target standalone); Total shares after deal = acquirer's old shares + new shares issued. Combined value includes synergy.
NPV of the merger to acquirer: NPV = Synergy − Cost; Positive NPV means acquirer's shareholders gain.
Goodwill on acquisition (Ind AS 103 style): Goodwill = Consideration − Fair value of net identifiable assets acquired; A negative result is a bargain purchase, which needs separate treatment.

How to solve Purchase Consideration and Payment Methods questions

Use this order for any question on purchase consideration, payment method or premium.

1List the data: shares and market price of both firms, offer terms, synergy, and whether the offer is cash, stock or mixed.
2Compute the standalone value of each firm (shares × price) unless a value is given.
3Work out the purchase consideration: cash plus shares issued at fair value plus any other payment to the target's shareholders.
4Compute the premium per share, the premium percentage and the total premium against the unaffected price.
5For a cash offer, cost = cash paid − target standalone value. For a stock offer, find the new shares, the combined value including synergy, the new share price and the value of the target holders' stake. Cost = that stake − target standalone value.
6Compute NPV = synergy − cost for each option. For stock, you can cross-check by finding the gain in the acquirer holders' own stake.
7Compare options and give a clear recommendation. Mention risk sharing, control dilution and what each side gets.
8If asked, compute goodwill as consideration minus fair value of net identifiable assets.

Quickest way: Premium and NPV shortcut

When to use it: Use when the exam asks for the better payment method or the gain to acquirer shareholders and time is short.

Cash NPV = synergy − (cash paid − target standalone value). Do this in one line.
For stock, compute the combined value and the acquirer holders' ownership share. Their NPV = (their share × combined value) − their old standalone value.
Check that both NPV methods agree if time allows.
Premium % comes straight from offer value per share ÷ unaffected price − 1.
Write the recommendation in one sentence, naming the option with the higher NPV.

Common mistakes in Purchase Consideration and Payment Methods

Measuring the premium against the current price after the announcement.
The market price already includes the expected offer, so it looks like the natural base.
Fix: Use the unaffected price before the news. If the question gives only one price, state your assumption.
Valuing shares issued at face value in the consideration.
Students copy the journal entry habit from accounting.
Fix: For valuation questions use the fair or market value per share. Use face value only to split the amount between share capital and securities premium.
Leaving synergy out of the combined value in a stock deal.
The cash case does not need the combined value, so the step is forgotten.
Fix: Combined value = acquirer + target + synergy. The new share price must be based on it.
Calculating the cost of a stock offer as shares issued × old acquirer price.
It feels the same as a cash deal.
Fix: Target holders receive shares worth the post-deal price. Use the new price, which already carries the synergy.
Assuming stock is always better or always worse than cash.
Students memorise a one-line rule.
Fix: Compare NPVs. Stock costs the acquirer more when synergy is large, since target holders share it. Cash costs more when the synergy is doubtful, since the acquirer carries all the risk.
Mixing per-share and total figures when finding the premium.
Data is given in rupees per share and in crores together.
Fix: Convert everything to one basis before subtracting. Write units next to each number.

Worked examples

Example 1

Alpha Ltd has 10,00,000 shares at ₹200 each. Beta Ltd has 4,00,000 shares at ₹100 each (unaffected price). Alpha expects synergy with a present value of ₹1,00,00,000. Option 1: Alpha pays cash of ₹120 per Beta share. Option 2: Alpha issues 1 share for every 2 Beta shares. Find the premium under each option, the NPV to Alpha's shareholders under each option, and recommend one.

Show the solution

Standalone values: Alpha = 10,00,000 × ₹200 = ₹20,00,00,000. Beta = 4,00,000 × ₹100 = ₹4,00,00,000.
Option 1 cash: total cash = 4,00,000 × ₹120 = ₹4,80,00,000. Premium = ₹20 per share = 20% on ₹100. Total premium = ₹80,00,000.
Cost of cash offer = ₹4,80,00,000 − ₹4,00,00,000 = ₹80,00,000. NPV = ₹1,00,00,000 − ₹80,00,000 = ₹20,00,000.
Option 2 stock: new shares = 4,00,000 × 1/2 = 2,00,000. Total shares = 12,00,000.
Combined value = 20,00,00,000 + 4,00,00,000 + 1,00,00,000 = ₹25,00,00,000. New price = ₹25,00,00,000 ÷ 12,00,000 = ₹208.33 (approx).
Value received by Beta holders = 2,00,000 × 208.33 = ₹4,16,66,667 (approx). Value per Beta share = ₹104.17, so premium is about 4.17%.
Cost of stock offer = ₹4,16,66,667 − ₹4,00,00,000 = ₹16,66,667. NPV = ₹1,00,00,000 − ₹16,66,667 = ₹83,33,333.
Cross-check: Alpha holders own 10/12 of ₹25,00,00,000 = ₹20,83,33,333, a gain of ₹83,33,333 over ₹20,00,00,000.

Answer: Cash: premium 20%, NPV ₹20,00,000. Stock: premium about 4.17%, NPV about ₹83,33,333. On NPV to Alpha, the stock offer is better. However, the stock offer gives Beta holders a much lower premium, so Beta may not accept it. Cash leaves Alpha with all the synergy risk but a bigger premium to Beta.

Example 2

Xenon Ltd takes over Yield Ltd, which has 1,00,000 equity shares with an unaffected market price of ₹36. Yield's shareholders get 3 Xenon shares for every 5 Yield shares, plus ₹20 cash per Yield share. Xenon's shares have a fair value of ₹40 each. The fair value of Yield's net identifiable assets is ₹40,00,000. Compute the purchase consideration, the premium and the goodwill.

Show the solution

Shares issued = 1,00,000 × 3/5 = 60,000 Xenon shares.
Value of shares = 60,000 × ₹40 = ₹24,00,000.
Cash = 1,00,000 × ₹20 = ₹20,00,000.
Purchase consideration = ₹24,00,000 + ₹20,00,000 = ₹44,00,000.
Value per Yield share = ₹44,00,000 ÷ 1,00,000 = ₹44.
Premium per share = ₹44 − ₹36 = ₹8. Premium % = 8 ÷ 36 × 100 = 22.22% (approx). Total premium = ₹8,00,000.
Goodwill = ₹44,00,000 − ₹40,00,000 = ₹4,00,000.

Answer: Purchase consideration ₹44,00,000; premium ₹8 per share (about 22.22%), total ₹8,00,000; goodwill ₹4,00,000.

Exam tips

Always show the premium against the unaffected price and state which price you used.
In stock deals, write the combined value, total shares and new price on separate lines. Marks are given for each step.
Finish with a recommendation that mentions NPV, risk sharing and the target's likely acceptance.
In the MCQ section, watch for questions that ask for cost, not NPV, or total premium, not per-share premium.
Keep consideration items at fair value and say so in your working.

Purchase Consideration and Payment Methods: frequently asked questions

How do I calculate purchase consideration in an amalgamation?

Add everything paid to the target's shareholders: cash plus shares issued at fair value plus any other agreed payment. Shares issued come from the exchange ratio. Do not include amounts the acquirer pays to outsiders unless the question says they form part of the deal.

Is a cash offer or a stock offer better for the acquirer?

There is no fixed answer. Compute the NPV for each. If synergy is large and certain, cash is usually cheaper for the acquirer because target holders do not share the gain. If the synergy is doubtful or the acquirer's shares look overpriced, stock shifts some risk to the target holders.

What is premium paid in a takeover?

It is the amount by which the offer value per share exceeds the target's unaffected market price. Express it in rupees and as a percentage of that price. Multiply by the number of target shares for the total premium.

How do I find the NPV of a merger cash offer?

First compute synergy as combined value minus the two standalone values. Then compute cost as cash paid minus the target's standalone value. NPV to the acquirer is synergy minus cost.
