Acquisition Strategy and Due Diligence for CS Professional

Updated 11 October 2026 · Fact-checked

Acquisition strategy is the plan that links an acquisition to the buyer's goals: why buy, what to buy, how much to pay and how to structure the deal. Due diligence is the buyer's structured check of the target's finances, legal position and business before signing. Together they decide whether, and on what terms, you proceed.

Understand Acquisition Strategy and Due Diligence

An acquisition starts with a strategic reason, not with a target. The buyer asks what it wants: entry into a new market, a product line, technology, capacity, cost savings or removal of a competitor. It then sets criteria for the target, such as size, sector, geography, profitability, and the price it can afford.

Next comes target identification and screening. The buyer builds a long list from industry research, advisers and approaches, and cuts it to a short list using the criteria. It then makes first contact, signs a non-disclosure agreement and often a letter of intent or MOU setting out broad terms. Exclusivity and confidentiality are usually included here.

Due diligence is the investigation that follows. Its purpose is to confirm what the seller says, find hidden liabilities, and test the price. The main types are:

Financial due diligence: quality of earnings, assets, debt, contingent liabilities, working capital, tax position and the reliability of projections.
Legal due diligence: title to assets, incorporation and statutory records, charges, contracts, litigation, licences, and compliance with the Companies Act and other laws.
Commercial due diligence: market position, customers, competition, growth prospects and whether the expected synergies are realistic.
Other reviews: tax, operational, HR and labour, environmental, and IT or data checks, as the deal needs.

Findings feed deal structuring. The buyer chooses between buying shares or buying the business or undertaking, the form of payment (cash, shares or a mix), how to protect itself (price adjustment, warranties, indemnities, escrow, conditions precedent), and how to finance the deal. Findings also affect the valuation and may lead to a lower price or walking away.

For the CS, the angle is compliance and documentation. Check approvals (board, shareholders, regulators, competition law where thresholds apply), and check the buyer's own limits. If the buyer is a company that acquires securities of another body corporate, Section 186 limits apply. Without prior special resolution, the total of loans, guarantees, security and investments cannot exceed the higher of 60% of paid-up share capital, free reserves and securities premium, or 100% of free reserves and securities premium. An acquisition of securities by a holding company in its wholly owned subsidiary is exempt from the special resolution requirement.

Key rules to remember

Section 186(2) investment limit: Limit = higher of (60% × [paid-up share capital + free reserves + securities premium]) and (100% × [free reserves + securities premium]); Covers loans, guarantees, security and acquisition of securities of other bodies corporate. Beyond this limit, a special resolution in general meeting is needed under Section 186(3).
Section 186(3) exemption: Special resolution not needed for loan, guarantee or security to a wholly owned subsidiary or joint venture company, or acquisition of securities of its wholly owned subsidiary by a holding company; Details must still be disclosed in the financial statements under Section 186(4).
Section 186(5) board approval: Board resolution passed at a meeting with the consent of all directors present; Prior approval of the public financial institution is also needed where a term loan is subsisting, subject to the proviso.
Section 186(13) penalty: Company: fine ₹25,000 to ₹5,00,000. Officer in default: up to 2 years' imprisonment and fine ₹25,000 to ₹1,00,000; Applies to contravention of Section 186.
Due diligence types: Financial + Legal + Commercial (+ tax, operational, HR, environmental, IT); A memory frame for answers. Link each type to the risk it covers.

How to solve Acquisition Strategy and Due Diligence questions

For any question on acquisition strategy or due diligence, use this sequence. It gives you provision, analysis and conclusion in a clear order.

1Read the facts and identify the buyer, the target, the deal type (shares or business) and what is asked: strategy, due diligence, structuring or compliance.
2State the strategic objective in a line, such as market entry, synergy or capacity, and the target criteria that follow from it.
3List the due diligence areas that matter for these facts: financial, legal, commercial and any special review such as tax, labour or environment.
4For each area, name the specific checks and the risk each one protects against, using the facts given.
5Link findings to deal structure and protection: price adjustment, warranties and indemnities, escrow, conditions precedent, choice of share or asset purchase.
6Apply the compliance points: board and shareholder approvals, Section 186 limits if the buyer is a company acquiring securities, and other regulatory approvals.
7Conclude with a clear recommendation: proceed, renegotiate or withdraw, and the next documents to draft.

Quickest way: Four-box answer: Why, Who, Check, Protect

When to use it: Use when time is short or the question asks to list or discuss due diligence or acquisition steps.

Why: one line on the strategic objective.
Who: target criteria and how the target is screened.
Check: financial, legal, commercial, plus one special review from the facts, each with one concrete check.
Protect: structure, warranties, indemnity, conditions precedent, approvals including Section 186 if relevant.

Common mistakes in Acquisition Strategy and Due Diligence

Writing due diligence as only a financial audit of the target.
Students link due diligence with accounts because numbers feel easier to write about.
Fix: Always cover legal and commercial reviews as well. Add at least one extra review that fits the facts, such as tax, labour or environmental.
Listing types of due diligence without linking them to risks.
Students memorise headings but do not explain why each exists.
Fix: For every type, write what is checked and what loss it prevents, for example title checks prevent buying assets the seller does not own.
Ignoring the buyer's own compliance limits.
Students focus on the target and forget the acquirer is also a company bound by law.
Fix: Check Section 186: the limit on acquiring securities, the special resolution when the limit is crossed, and the board resolution with consent of all directors present.
Stating that Section 186 special resolution is needed for every acquisition of shares.
Students overlook the thresholds and the exemption.
Fix: The special resolution is needed only when the aggregate crosses the Section 186(2) limit. A holding company acquiring securities of its wholly owned subsidiary is exempt from it.
Treating due diligence as a one-time step before signing only.
The textbook sequence puts it before the agreement.
Fix: Explain that findings drive price, structure and conditions, and that confirmatory checks continue until closing.
Giving a generic answer with no conclusion.
Case answers are rushed.
Fix: End with a recommendation tied to the facts: proceed, renegotiate with indemnity or price cut, or withdraw.

Worked examples

Example 1

Aarav Industries Ltd plans to buy 100% shares of Meridian Components Pvt Ltd to enter the auto-parts market. Advise the board on the due diligence it should conduct before signing.

Show the solution

Objective: Aarav wants market entry and capacity, so the review must test whether Meridian's business actually delivers these.
Financial due diligence: verify audited accounts, quality of earnings, debt, contingent liabilities, working capital and tax position. This protects against overpaying for inflated profits or hidden debt.
Legal due diligence: check incorporation and statutory records, share title, charges on assets, material contracts, licences, litigation and compliance with the Companies Act. This protects against defective title and undisclosed claims.
Commercial due diligence: examine customer concentration, competition, order book and realism of synergies. This tests the case for entry.
Special reviews: labour and environmental compliance, because auto-parts manufacturing carries such risks, and IT or data if relevant.
Link to structure: use findings to adjust price, obtain warranties and indemnities, set an escrow for contingent claims, and make key approvals conditions precedent.
Compliance: board resolution with consent of all directors present, and a Section 186 check as Aarav is acquiring securities of another body corporate.

Answer: Aarav should run financial, legal and commercial due diligence, with tax, labour and environmental reviews added, and use the findings to fix price, warranties, indemnity, escrow and conditions precedent, while complying with Section 186 and board approval requirements.

Example 2

Kaveri Ltd has paid-up share capital of ₹40 crore, free reserves of ₹30 crore and securities premium of ₹10 crore. It has no existing loans, guarantees or investments in other bodies corporate. It proposes to acquire 25% of an unrelated company, Lotus Foods Ltd, for ₹55 crore. Is a special resolution under Section 186 needed?

Show the solution

Section 186(2) limit is the higher of two amounts.
First amount: 60% of (paid-up capital + free reserves + securities premium) = 60% × (40 + 30 + 10) = 60% × ₹80 crore = ₹48 crore.
Second amount: 100% of (free reserves + securities premium) = 30 + 10 = ₹40 crore.
The higher is ₹48 crore, so that is the limit.
Aggregate with the proposed acquisition = 0 + ₹55 crore = ₹55 crore, which exceeds ₹48 crore.
Under Section 186(3), the investment needs prior authorisation by a special resolution in general meeting. Lotus Foods is not a wholly owned subsidiary, so the exemption does not apply.
Also, under Section 186(5), the board resolution must be passed at a meeting with the consent of all directors present. Prior approval of a public financial institution is needed if a term loan is subsisting, because the limit is exceeded. Details must be disclosed in the financial statements under Section 186(4).

Answer: Yes. The limit is ₹48 crore, the proposed investment is ₹55 crore, so Kaveri Ltd needs a special resolution in general meeting, in addition to a board resolution with the consent of all directors present.

Exam tips

Structure every case answer as provision, analysis, conclusion. Name the type of due diligence and tie it to a fact in the question.
If the buyer is a company, always test Section 186. Show the two-limb calculation and pick the higher figure.
Mention the practical drafting outputs: NDA, MOU or letter of intent, due diligence report, share purchase or business transfer agreement with warranties and indemnities.
Do not cite section numbers you are unsure of. Use plain words for other approvals, such as regulatory and competition approvals.
Close with a decision: proceed, renegotiate or withdraw, with the reason.
