Adjusted Options: Reading an OCC Memo

A corporate action can change what an option delivers. The ticker and strike alone are not enough to value an adjusted contract. Read the current OCC information memo, any updates and the broker’s contract description before comparing it with a standard option.

Read these fields separately

• Effective date and symbol: identify when the adjustment applies and which series it affects.
• Contract-count factor: determine how many contracts replace the old position.
• Strike adjustment: identify the new strike or strike divisor.
• Premium / strike dollar multiplier: convert quoted points into cash.
• Deliverable: list the actual shares, cash and any other components received or delivered on exercise.

The word “multiplier” can describe different fields. A two-for-one contract-count adjustment is not the same thing as changing the premium dollar multiplier from 100 to 200.

A real memo: a two-for-one split

OCC memo 59423, dated July 21, 2026, describes the SFBS split effective August 21, 2026. It specifies a contract-count factor of 2, strike divisor of 2, a 100 dollar multiplier and 100 shares per resulting contract. The symbol remains SFBS.

Applying those fields to a teaching position of one $80 call gives two $40 calls. Aggregate exercise cash remains $8,000: initially 1 × $80 × 100 and afterward 2 × $40 × 100. This memo does not imply that every split produces the same adjustment, especially reverse splits or transactions involving cash.

A hypothetical nonstandard deliverable

Suppose a different memo specifies that one adjusted call delivers 25 shares plus $100 cash, while its $20 strike still extends with a 100 multiplier. Exercise costs $2,000. If the stock is $80, the deliverable is worth 25 × $80 + $100 = $2,100, so immediate exercise value is $100 per contract.

Computing ($80 − $20) × 100 would incorrectly produce $6,000. The quoted strike is applied to the specified exercise cash, while the underlying deliverable is valued component by component. A $1.40 premium with a 100 quote multiplier costs $140 even though only 25 shares are delivered.

Check unresolved details

Cash in lieu of fractional shares may be determined later. A merger can accelerate expiration or alter exercise treatment, and updated memos can supersede earlier terms. Record memo numbers and the exact version used. Confirm that spread legs have compatible deliverables; identical displayed strikes do not guarantee matching exposure.

Adjusted series can also have limited trading interest. A correct intrinsic-value calculation is not a guarantee of an executable exit price. Use the memo to establish contract economics and the actual quote to assess execution.
