Exam-critical pointers

  • Bootstrapping EPS: acquirer with high P/E acquires low P/E target — accounting EPS rises but no real value.
  • Buy-back vs Dividend — tax-efficient distribution in India.
  • SEBI Takeover Code triggers at 25% (open offer for 26%).
  • NCLT scheme of arrangement (Sec 230-232 Companies Act) for mergers.

Elaborative notes

Mergers, Acquisitions & Corporate Restructuring

M&A is AFM's integrative chapter — it stitches valuation, capital structure,

synergy quantification, share-swap mechanics, and SEBI takeover regulation

into a single applied case. Questions are typically case-style with multiple

sub-parts adding to 8–14 marks.

1. Types of M&A

TypeDefinitionStrategic intent
HorizontalSame industry, same stageScale, market share, eliminate competitor
VerticalBuyer / supplier in same value chainControl of inputs (backward) or distribution (forward)
ConglomerateUnrelated industriesDiversification, capital deployment
ConcentricRelated but different industriesCross-selling, shared technology

2. Motives — synergy decomposition

Synergy = Value of combined firm − Sum of standalone values.

Synergy = V(AB) − [V(A) + V(B)]

Four flavours:

  1. Operating synergy (cost) — shared SG&A, plant consolidation, supply

chain integration.

  1. Operating synergy (revenue) — cross-sell, geographic expansion,

bundling.

  1. Financial synergy — lower WACC from combined credit profile, tax

benefits from offset losses, more efficient capital allocation.

  1. Tax synergy — Section 72A IT Act allows brought-forward losses of

an amalgamating company to be carried forward by the amalgamated

company (industrial conditions apply).

3. Valuation in M&A

Standard approaches, applied side-by-side:

ApproachUse
DCFStandalone value, then add PV of synergies
Comparable company multiplesMarket sanity check
Precedent transactionsWhat did similar deals price at?
Asset-basedLower bound (liquidation / book value floor)

The acquirer's offer band: **floor = standalone value of target; ceiling =

standalone + PV of expected synergies.** A topper answer always shows both.

4. Share-swap ratio

When consideration is paid in stock, the swap ratio is the number of

acquirer shares offered per target share.

Swap ratio (EPS-based) = EPS of target / EPS of acquirer

Swap ratio (MPS-based) = MPS of target / MPS of acquirer

ICAI almost always asks for both and the comparison.

5. Post-merger EPS / MPS

Post-merger EPS = (NI_A + NI_B + Synergy_PAT) / (Shares_A + ER × Shares_B)

where ER = exchange ratio.

Post-merger MPS = Post-merger EPS × P/E_AB

EPS accretive = post-merger EPS > acquirer's pre-merger EPS.

EPS dilutive = post-merger EPS < acquirer's pre-merger EPS.

A high-P/E acquirer buying a low-P/E target with stock is typically EPS

accretive even with zero real synergy — this is the bootstrapping trap

that examiners flag. Topper answers state explicitly: "accounting accretion

is not value creation."

6. Maximum exchange ratio acceptable to acquirer

Acquirer's shareholders are not made worse off iff the post-merger MPS ≥

acquirer's pre-merger MPS.

ER_max × Shares_B = (V(AB) − Shares_A × MPS_A_pre) / MPS_A_pre

Algebraically: acquirer can pay up to the full PV of synergies in stock

before shareholders lose.

7. Defence mechanisms (theory questions)

DefenceMechanism
Poison pillExisting shareholders get rights to buy more shares at discount, diluting acquirer
White knightFriendly third-party acquirer rescues target
Crown jewelSell off the most attractive asset before takeover completes
Golden parachuteGenerous severance for executives — raises acquisition cost
Pac-ManTarget turns around and bids for acquirer
GreenmailTarget buys back acquirer's stake at premium

8. Indian regulatory overlay

  • SEBI Takeover Code (SAST Regulations 2011) — triggers an open offer

if acquirer's stake crosses 25%. Open offer must be for at least 26% of

remaining shares.

  • Companies Act 2013 — Sections 230–232 — NCLT scheme of arrangement

for mergers, amalgamations, demergers. Approval requires creditors (75%

by value) and shareholders (75% by value).

  • Section 72A IT Act — carry-forward of losses on amalgamation.
  • Competition Act 2002 — CCI approval required if combined assets

exceed threshold limits.

9. ICAI exam patterns

Question shapeTypical marks
Swap ratio (EPS + MPS) + decision6–8
Synergy quantification + per-share value6
Maximum ER for acquirer4
Post-merger EPS / MPS / gain to each side8
Defence mechanism theory4
SEBI takeover code triggers4
Demerger / spin-off valuation6

M&A appears in most attempts as one full 8-mark question.

10. The 60+ marks topper convention

  • Lay out the deal in a 3-column table — Acquirer / Target / Combined —

with EPS, P/E, MPS, NI, Shares for each.

  • Compute swap ratios separately by EPS and MPS — show both, then

recommend.

  • Identify the bootstrapping trap explicitly when relevant — "EPS

accretion of X% is purely a P/E differential, not value creation."

  • For acquirer-acceptability questions, state the inequality

Post-merger MPS ≥ Pre-merger MPS — and solve for ER.

  • Cite the SAST trigger and Companies Act section — earns the

authority mark.

  • Box the swap ratio and the verdict.

Worked examples

Worked example — Swap ratio + EPS impact

Acquirer Ltd. plans to take over Target Ltd. on a share-swap basis.

ParticularsAcquirerTarget
EPS (₹)2412
P/E Ratio1812
MPS (₹)432144
Shares (Cr)52
NI (₹ Cr)12024

Synergy gains expected: ₹40 Cr p.a. (PAT). Post-merger P/E expected = 17.

Step 1 — Swap ratios

EPS-based: 12 / 24 = 0.50 acquirer shares per target share

MPS-based: 144 / 432 = 0.333 acquirer shares per target share

Step 2 — Compare and recommend

EPS-based is more favourable to target (acquirer pays more per target

share). MPS-based reflects market reality. **Negotiation band: 0.333 to

0.50.** Most deals settle near MPS-based with a control premium.

Assume the agreed ER = 0.40.

Step 3 — Post-merger figures

Combined NI = 120 + 24 + 40 (synergy) = ₹184 Cr

Combined shares = 5 + 0.40 × 2 = 5.80 Cr

Post-merger EPS = 184 / 5.80 = ₹31.72

Post-merger MPS = 31.72 × 17 = ₹539.20

Step 4 — Gain to each side

Acquirer:

  • Pre-merger MPS = ₹432
  • Post-merger MPS = ₹539.20
  • Gain per share = ₹107.20 (= 24.8% accretion)

Target:

  • Pre-merger: 1 share × ₹144 = ₹144
  • Post-merger: 0.40 shares × ₹539.20 = ₹215.68
  • Gain per target share = ₹71.68 (= 49.8% premium)

Step 5 — Maximum acceptable ER to acquirer

Acquirer not worse off iff post-merger MPS ≥ ₹432.

Post-merger MPS = [(120 + 24 + 40) / (5 + ER × 2)] × 17 ≥ 432

184 × 17 / (5 + 2·ER) ≥ 432

3128 / (5 + 2·ER) ≥ 432

5 + 2·ER ≤ 3128 / 432 = 7.241

ER ≤ **1.12**

Final answer: The negotiated ER of 0.40 is well within the acquirer's

maximum acceptable ratio of 1.12, leaving substantial headroom. Both sides

benefit — recommend proceeding.

Pitfalls examiners flag

Common pitfalls

  1. Conflating swap ratio and exchange ratio. Swap ratio is target →

acquirer (₹x of target for ₹y of acquirer). Exchange ratio (ER) is the

number of acquirer shares per target share. They are the same number when

stated consistently — but students often invert them.

  1. Forgetting synergy in post-merger NI. When synergy is a PAT figure,

add it directly to (NI_A + NI_B). When it's a pre-tax synergy, deduct

tax first.

  1. Using book value for swap ratio. Always market value (MPS) or

earnings (EPS). Book value swap is almost never the right answer in AFM.

  1. **Treating "minimum swap ratio acceptable to target" as same as

"maximum acceptable to acquirer".** They're opposite ends — target wants

higher (more acquirer shares); acquirer wants lower.

  1. Missing the SEBI 26% open-offer rule. Trigger is 25%, but the

offer must be for at least 26% of remaining (not 25%). Students often

write the wrong number.

  1. Confusing demerger and spin-off tax treatment. Demerger under

Section 2(19AA) IT Act has specific tax-neutral conditions; a normal

spin-off does not automatically qualify.

30-second revision card

M&A — 30-second recap

  • Types: horizontal, vertical, conglomerate, concentric
  • Synergy = V(AB) − V(A) − V(B); decompose into cost / revenue / financial / tax
  • Swap ratio: EPS_t / EPS_a OR MPS_t / MPS_a — show both
  • Post-merger EPS = (NI_A + NI_B + Syn) / (Sh_A + ER·Sh_B)
  • Bootstrap trap: high-P/E buys low-P/E with stock = accounting EPS up, no value
  • ER_max = max value of synergy paid in stock without diluting acquirer MPS
  • SEBI SAST trigger at 25% → open offer for 26%
  • Companies Act 230–232 + NCLT scheme; Section 72A for loss carry-forward
