Options Assignment Risk Checklist

An options assignment risk checklist is a pre-expiration review that helps you understand what could happen if a short option is exercised. The goal is not to predict every assignment. The goal is to know the obligation, the capital impact, and the decision points before the position gets noisy.

Quick definition

Assignment means an option holder exercises the contract and the option seller receives the matching obligation. A short call can create an obligation to deliver shares. A short put can create an obligation to buy shares. Index-settled, cash-settled, and futures options can work differently, so the first checklist item is always the actual contract specification.

The assignment rule

Before expiration week, write the contract type, settlement style, strike, expiration, extrinsic value, open risk, buying-power effect, and what you would do if assigned. If the position cannot survive the assignment scenario on paper, it should not be ignored just because the option is still out of the money.

What to check before expiration

Start with moneyness. Is the option in the money, near the money, or moving quickly toward the strike? Then check extrinsic value. Options with very little extrinsic value can carry different exercise incentives than options with meaningful time value. Then check dividends, borrow costs, settlement rules, liquidity, and whether your broker has cut-off times or exercise/assignment procedures you need to understand.

Simple example

Suppose a trader is short one $50 put on a stock. One equity option contract usually represents 100 shares, so assignment could create a 100-share purchase at $50, or $5,000 of stock exposure before fees and margin treatment. If the account only planned for a $300 options risk decision, that assignment scenario is a different problem and needs a written plan.

Mistakes to avoid

Do not treat probability as a substitute for preparation. Do not assume assignment only happens at expiration. Do not ignore cash or buying-power effects. Do not let a small premium position quietly turn into an oversized stock position. And do not rely on generic rules when the actual product has specific settlement terms.
