## Shares with Different Nominal Values
When a company has equity shares of different face values (e.g., some at ₹10 and others at ₹5), they cannot be mixed in WANES directly — each rupee of face value represents a different economic interest.

### Rule under AS 20
Convert all share classes to equivalent shares of a common nominal value before combining.
$$\text{Equivalent Shares} = \text{No. of Shares} \times \frac{\text{This Class's Face Value}}{\text{Common Base Face Value}}$$

### How to Calculate EPS
1. Choose one face value as the common base (typically the dominant class).
2. Convert each class to equivalent shares of that base value.
3. Time-weight each class from its date of issue.
4. Combine to get total WANES.
5. Basic EPS = EAFESH / combined WANES — this EPS is per share of the base face value.
6. EPS per share of another class = Base EPS × (Other Class FV / Base FV).
