The Rapid-Fire Revision Clinic accelerates ⚡📊 into one of the most time-sensitive calculations on the SOCPA exam: IAS 33.

This session focuses on the shortcuts and decision rules that determine which potential ordinary shares belong in Diluted EPS—and which must be ignored.

Because the biggest time-waster in EPS questions is calculating instruments that turn out to be anti-dilutive.

⸻

Key subjects covered in this session:

• The “Stop” Rule 🛑

If the company reports a Loss Per Share, stop immediately.

No instrument can make a loss per share more negative and therefore dilutive.

Result:

Loss per share → Basic EPS = Diluted EPS

No further calculations required.

⸻

• The “In-the-Money” Hack 💡

For options and warrants, use a quick test with the Average Market Price (AMP).

If:

Market Price > Exercise Price → Dilutive

If:

Market Price ≤ Exercise Price → Anti-dilutive

Why?

No rational investor would exercise an option that costs more than buying shares in the market.

⸻

• Incremental EPS Test 📉

For convertible bonds or convertible preference shares, use the incremental EPS test.

Calculate the additional EPS effect:

EPS = After - tax interest saved/Additional shares

Then compare it to Basic EPS.

• If incremental EPS < Basic EPS → dilutive → include

• If incremental EPS > Basic EPS → anti-dilutive → exclude

The instrument must reduce EPS, not increase it.

⸻

• Treasury Stock Method Simplified 🔄

Options and warrants follow the Treasury Stock Method.

Logic:

1️⃣ Assume options are exercised

2️⃣ Company receives cash from exercise

3️⃣ That cash hypothetically repurchases shares at market price

The difference creates “free shares”.

Only those free shares increase the denominator in Diluted EPS.

⸻

• The Exam Room Checklist 🧠

Before calculating Diluted EPS, filter instruments quickly:

1️⃣ Is EPS already a loss? → stop.

2️⃣ Are options in the money?

3️⃣ For convertibles, apply incremental EPS test.

4️⃣ Exclude any anti-dilutive instruments.

Then calculate diluted EPS using only the surviving instruments.

⸻

Rapid Exam Logic (SOCPA Focus) 🎯

Diluted EPS always follows one rule:

Include only instruments that decrease EPS.

Everything else must be excluded.

If you apply this filter first, most complicated EPS questions become a two-step calculation instead of a full multi-instrument model.

That shortcut alone can save significant time during the exam.
