Adjusted Options: Check What the Contract Actually Delivers
Why a familiar strike and ticker can hide a different obligation after a split, merger or distribution.
Worth reading first: What an Option Contract Actually Is
Course catalogue99 lessons
Most equity-option examples assume one contract represents 100 shares. Corporate actions can break that assumption. An adjusted option can deliver a different share quantity, cash, or a basket of securities. A familiar ticker and strike are not enough to establish what you are selling or whether your shares cover it.
Separate premium multiplier, exercise amount and deliverable
The premium multiplier converts the quoted premium into cash. The aggregate exercise amount specifies cash paid or received on exercise. The deliverable specifies what changes hands in exchange. These fields need not scale together after an adjustment.
| Field | Hypothetical adjusted contract | Meaning |
|---|---|---|
| Quoted premium | $1.20 | Quote alone does not identify the deliverable |
| Premium multiplier | 100 | $120 premium per contract |
| Displayed strike | $20 | Check aggregate exercise amount in the memo |
| Aggregate exercise amount | $2,000 | Cash exchanged per exercised contract |
| Deliverable | 10 post-action shares | Not 100 post-action shares |
An illustrative specification, not a live contract. Always obtain the actual adjustment memo.
If those 10 shares trade at $180 each, the deliverable is worth $1,800. Compared with a $2,000 exercise amount, the put has $200 of intrinsic value per contract. If its premium multiplier is 100, that corresponds to $2 of quoted intrinsic value. Comparing the displayed $20 strike directly with the $180 share price would reach the wrong moneyness conclusion.
What can trigger an adjustment?
Splits, mergers, spinoffs and certain distributions can change outstanding contracts. A split does not always preserve the original contract count and change only the strike; the adjustment method depends on the action. Ordinary cash dividends and special distributions also need different treatment. The authoritative answer is the specific clearing memo and its effective date, not a rule inferred from the word “dividend.”
Check the contract before trading or importing it
- Record the complete option symbol and identify the adjustment memo.
- Verify premium multiplier, aggregate exercise amount, each deliverable component and effective date.
- Recalculate intrinsic value from total deliverable value, not a standard share-price shortcut.
- Verify actual coverage, collateral and how the broker handles cash or fractional components.
- Check liquidity in that exact series; a liquid standard chain does not guarantee a liquid adjusted chain.
- Retain the memo with the original fills and corporate-action records for reconciliation.
Do not force an adjusted contract into a tracker as a standard 100-share option merely to obtain a tidy chart. If the application cannot represent the full deliverable, keep a separate reconciliation and flag the limitation. This is especially important when rebuilding historical activity or reconciling broker statements.

Key takeaways
- An adjusted contract may deliver something other than 100 shares.
- Premium multiplier and deliverable quantity are separate fields.
- Determine moneyness from aggregate deliverable value and exercise amount.
- Use the actual memo; do not assume a standard and adjusted option form a matched hedge.
Check your understanding
1. A contract delivers 10 shares worth $180 each for a $2,000 exercise payment. Put intrinsic value per contract?
