Early Assignment In-The-Money Call Haircut
The Formal Definition
The unexpected financial loss incurred by a short call option seller who is assigned early prior to an ex-dividend date, requiring them to deliver physical shares and reimburse the buyer for the gross dividend payment out-of-pocket.
Assignment Haircut = Gross Corporate Dividend per Share ($) × 100 Shares per Contract (Triggered when Remaining Extrinsic Call Value < Dividend Amount)
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Selling covered calls seems safe until dividend week arrives. If your short call is in-the-money and the stock is about to go ex-dividend, the buyer will exercise early to steal the dividend. If you are short that call, you get assigned. You are forced to deliver the shares, and your broker debits your cash balance to pay the buyer their dividend check."

Real-World Example: Scenario Breakdown
Examining the real numbers for: Short 10 In-the-Money Call Options ($90 Strike) on a stock trading at $95 that pays a $2.00 dividend tomorrow (Extrinsic value: $0.40)
| Execution Metric | Dividend-Aware Covered Call Writer | Unaware Covered Call Writer (Early Assignment) |
|---|---|---|
| Fee / Rate | $0.65 fee | $0.65 fee |
| Spread / Buffer | Noticed remaining extrinsic value ($0.40) was less than the dividend ($2.00) | Left in-the-money call positions open overnight into the ex-dividend date |
| Execution / Status | Closed short call contracts for a small profit at 3:55 PM before the ex-dividend date | Counterparty exercised early; shares called away at $90 on the eve of the ex-date |
| Total Cost / Result | Clean options risk management | Suffered a $2,000 loss from an unmanaged early assignment trigger |
How Brokers Weaponize This Term
Discount options brokers omit early assignment warning alerts on options chains, allowing uneducated retail covered-call writers to lose corporate dividend distributions to institutional option exercisers.

Why would an option holder exercise an in-the-money call early?
To capture an upcoming dividend payment; if the dividend is larger than the remaining extrinsic (time) value of the call, exercising early is mathematically optimal.
Can you be assigned early on a short put option?
Yes. Deep in-the-money put options are frequently exercised early when the cost of carry and interest that can be earned on the strike cash exceeds the put's remaining extrinsic value.
