The Options Clearing Corporation (OCC)

Now that you understand what options contracts are and how they're structured, the next question is: who guarantees that the buyer actually gets what they paid for? That's where the OCC comes in.

Role and Function

The Options Clearing Corporation (OCC) plays three key roles in the options market:

  • Issuer: The OCC issues every listed options contract traded on U.S. exchanges
  • Guarantor: The OCC guarantees performance on every contract. If a writer defaults, the OCC steps in
  • Central counterparty: Once a trade is matched on the exchange, the OCC interposes itself between buyer and seller, becoming the buyer to every seller and the seller to every buyer

This structure eliminates counterparty risk:

  • The buyer does not need to worry about whether the seller can deliver
  • The seller does not need to worry about whether the buyer can pay
  • Both sides deal exclusively with the OCC

The OCC also standardizes contract terms (underlying, strike, expiration, contract size), which makes options fungible: any contract with identical terms is interchangeable, allowing free trading on the secondary market.

Exam Tip: Gotchas

  • The OCC is both the issuer and guarantor of listed options. If the exam asks "Who issues options?", the answer is the OCC, not the exchange, not the buyer, and not the seller. The exchange provides the marketplace; the OCC provides the contract.

Exercise and Assignment

When a holder decides to exercise an option, here's the process:

  1. The holder notifies their broker
  2. The broker notifies the OCC
  3. The OCC randomly assigns the exercise notice to a member firm with a short position in that series
  4. The member firm assigns the notice to one of its customers

Member firms must use one of two assignment methods:

  • Random selection
  • First-in, first-out (FIFO)

The firm must disclose its assignment method to customers in advance.

Key point: The holder chooses whether to exercise, but the writer has no choice. Assignment is involuntary and random.

Exam Tip: Gotchas

  • Assignment is random from OCC to member firm. The firm then uses random or FIFO to assign to a specific customer.
  • The holder controls whether to exercise, but the writer cannot refuse assignment.

The Options Disclosure Document (ODD)

The OCC publishes a document titled "Characteristics and Risks of Standardized Options", commonly known as the Options Disclosure Document (ODD).

  • The ODD must be delivered to a customer at or before the time the account is approved for options trading
  • A hyperlink to the ODD satisfies the delivery requirement
  • The ODD explains the mechanics and risks of options trading, not specific recommendations

Exam Tip: Gotchas

  • The ODD must be delivered at or before account approval, not after. A hyperlink to the document satisfies the delivery requirement.
