Amount to be credited to Calls-in Arrears account at the time of forfeiture is:

Looking at the details:

Share details:

• Issue price: ₹100 + 10% premium = ₹110
• Application: ₹40 (including premium)
• Allotment: ₹45
• First and Final call: ₹110 - ₹40 - ₹45 = ₹25

Pro rata allotment calculation:

• Applications received: 50,000 shares
• Applications rejected: 10,000 shares
• Valid applications: 40,000 shares
• Shares to be allotted: 30,000 shares
• Allotment ratio: 30,000:40,000 = 3:4

For the shareholder who applied for 400 shares:

Shares allotted = 400 × $\frac{3}{4}$ = 300 shares

Application money paid = 400 × ₹40 = ₹16,000

Application money required for 300 shares = 300 × ₹40 = ₹12,000

Excess application money = ₹16,000 - ₹12,000 = ₹4,000 (adjusted towards allotment)

Calls in arrears calculation:

Allotment due on 300 shares = 300 × ₹45 = ₹13,500

Less: Excess application adjusted = ₹4,000

Net allotment unpaid = ₹9,500

Call money unpaid = 300 × ₹25 = ₹7,500

Total Calls-in-Arrears = ₹9,500 + ₹7,500 = ₹17,000

At the time of forfeiture, this amount in arrears is written off by crediting the Calls-in-Arrears account (to close it).
