Step Acquisition and Remeasurement: Gaining Control in Stages

One of the trickier consolidation scenarios CA students encounter is when a parent company gradually builds its stake in another entity until it crosses the threshold of control. This process—acquiring a subsidiary in stages—is called a step acquisition. Today, let's walk through the accounting logic and see why remeasurement matters.

What Is a Step Acquisition?

Imagine Company A buys 30% of Company B's shares in Year 1 as a passive investment. In Year 2, it buys another 35%. Suddenly, it has 65% and gains control. That transition moment creates a unique accounting event: the prior 30% investment must be remeasured.

A step acquisition happens when control is obtained through multiple purchases over time, rather than a single transaction.

The Core Principle: Remeasurement at Fair Value

Here's the key concept: on the date control is first obtained (the acquisition date), all previously held equity interests in the future subsidiary are remeasured to fair value. This is not optional—it's mandatory under Ind AS 103.

Why remeasure? Because from that moment, the investee becomes a subsidiary and must be consolidated. The old 'passive investment' accounting no longer applies. The parent must recognize any gain or loss on remeasuring the earlier stake to fair value on the acquisition date.

Worked Logic Example

Let's work through a straightforward scenario:

Transaction Timeline:

  • 1 January 20X1: Company P buys 25% of Company S for ₹50 lakhs. Recognized as an investment at cost. No special accounting.
  • 1 July 20X2: Company P buys another 40% of Company S for ₹95 lakhs. Now P holds 65% and gains control.
  • Fair value of P's original 25% stake on 1 July 20X2: ₹58 lakhs.

Accounting Entry on 1 July 20X2 (acquisition date):

Step 1: Remeasure the prior 25% stake from its carrying amount to fair value.

  • Carrying amount of 25% stake: ₹50 lakhs
  • Fair value of 25% stake: ₹58 lakhs
  • Gain on remeasurement: ₹8 lakhs

Journal Entry:

Investment in S (25% stake) Dr. ₹8 lakhs Gain on Remeasurement of Investment Cr. ₹8 lakhs

Step 2: Record the new 40% purchase at cost.

Investment in S (40% stake) Dr. ₹95 lakhs Cash Cr. ₹95 lakhs

Total carrying amount of investment in S (before consolidation): ₹50 lakhs + ₹8 lakhs + ₹95 lakhs = ₹153 lakhs.

This ₹153 lakhs becomes the parent's contribution to the consolidated balance sheet for the subsidiary stake (before goodwill calculation).

Where Does the Remeasurement Gain Appear?

The ₹8 lakhs gain is recognized in the consolidated statement of profit and loss in the year control is gained. It is not added to goodwill. Many students mistakenly try to capitalize it; remember, it is a separate profit or loss item arising from remeasurement.

If the remeasurement had resulted in a loss (fair value of ₹48 lakhs instead of ₹58 lakhs), you would record a loss of ₹2 lakhs, which would also flow through profit and loss.

Goodwill Calculation in a Step Acquisition

Once remeasurement is done, goodwill is calculated using the fair value of consideration transferred plus the fair value of any non-controlling interest, minus the fair value of identifiable net assets.

Simplified formula:

Goodwill = (Fair value of consideration for 40% + Fair value of 25% stake at acq. date + Fair value of NCI % stake) − Fair value of S's net assets

In our example, if the fair value of S's identifiable net assets on 1 July 20X2 is ₹200 lakhs:

Goodwill = (₹95 lakhs + ₹58 lakhs) − (65% × ₹200 lakhs) = ₹153 lakhs − ₹130 lakhs = ₹23 lakhs

Note: The remeasured 25% stake (₹58 lakhs) is already at fair value, so it goes directly into goodwill calculation.

Common Student Mistakes

Mistake 1: Treating the remeasurement gain as part of goodwill. Correction: The gain flows to P&L. Only the fair value of the stake itself contributes to goodwill.

Mistake 2: Using the old carrying amount (₹50 lakhs) in goodwill calculation instead of fair value (₹58 lakhs). Correction: Always use fair value on the acquisition date for consolidation.

Mistake 3: Forgetting to remeasure if the investment was previously held at equity method. Correction: Equity-method investments must also be remeasured to fair value on the date control is obtained.

Step Acquisition vs. Outright Purchase

Why does this matter in practice? When a parent buys control in stages, the acquisition cost (for goodwill purposes) can look different from the total cash paid. The remeasurement ensures that fair values—not historical costs—drive consolidation, giving a truer economic picture on day one of the new parent-subsidiary relationship.

Practical Reminders

  • Remeasurement is mandatory once control is obtained, regardless of whether the earlier stake was negligible or large.
  • Both gains and losses on remeasurement are recognized in profit and loss.
  • The acquisition date is the date control is first obtained, not the date of the final purchase.
  • Always verify the latest Ind AS 103 guidance in your ICAI study material for any nuances on measuring fair value in your specific scenario.

FAQs

Q1: If I bought 25% five years ago and now buy 40% more to gain control, do I still remeasure the old 25%? Yes. No matter how old the earlier investment, the moment you gain control, all prior interests are remeasured to fair value on that acquisition date. This ensures consolidated values reflect current economics.

Q2: What if the fair value of my earlier stake drops below what I paid for it? You record a loss on remeasurement in profit and loss. This is a real economic event—the prior investment is now worth less. The loss is not ignored; it simply flows through the income statement.

Q3: Does remeasurement apply if I already owned an equity-method investment? Yes. If you held an investment using the equity method (recording your share of the investee's profit/loss annually), you must still remeasure it to fair value on the date you gain control.

Step acquisitions test your understanding of consolidation logic and fair value principles. The remeasurement rule ensures that when a parent finally consolidates a subsidiary, the balance sheet reflects the true economic contribution of all prior equity interests. Master this concept, and you've conquered one of CA Intermediate's trickier topics.
