Additional Paid-In Capital (APIC)

Also called APIC

Additional Paid-In Capital is a line under Shareholders’ Equity on the Balance Sheet that represents the amount investors pay for a company’s stock above its par value, reflecting the premium received from issuing shares.

Example

A company issues 1,000,000 shares of common stock with a par value of $0.01 per share at a market price of $10 per share:

Par Value: $0.01 × 1,000,000 = $10,000 → Recorded as "Common Stock" on the balance sheet.

Additional Paid-In Capital: ($10 - $0.01) × 1,000,000 = $9,990,000 → Recorded under APIC.

The shareholders' equity section would look like this:

  • Common Stock: $10,000
  • Additional Paid-In Capital: $9,990,000
  • Total Equity Contribution from Common Stock: $10,000,000

💡 APIC isn’t critical for interviewing but is good to know.

Why Additional Paid-In Capital (APIC) matters in investment banking interviews

APIC is where the real money investors paid actually sits, since par value is nominal. It also grows with stock-based compensation, which is the connection worth knowing.
